“Morning Tom,” I said as I approached the security desk, tucking my travel cup into the crook of my arm to retrieve my ID badge. I held it over the scanner until the light went green.

“Morning Steve,” the balding guard said, rising from his chair and hoisting his trousers up as he did. “Step on the blue dot please sir.”

I did as instructed, straightening my posture and standing still as Tom went over to one of his screens and started typing on the keyboard. The scanner began to warm up, and over the low hum I could hear the news report from the small TV Tom had been watching.

“—raiding the warehouse with little success for the Wardens yesterday afternoon. Witnesses reported to have seen the likes of Icarus and Watcher in the skies moments before Density and the Expando infiltrated the building. Police were quick on the scene thereafter suggesting a joint effort, but as they were cordoning off the area, Icarus and Watcher flew down to meet a disgruntled Density. It seems that the Body Builder is still at large.”

I tried to surpass a snort at the reporter’s terrible pun. It was such an odd name for the scrawny nutjob running around robbing banks and the like by causing random people to grow into muscle men he would control like his own personal army. The bright side was that both the transformation and the mind control were short lived. From the reports I’d heard earlier, the mind control only worked when the subject was under the influence of the Body Builder’s formula, which he would administer with a dart gun. His target would swell up with muscle and mass and then, somehow, they would do as he commanded, be it ripping safe doors off their hinges, knocking down walls or even throwing cars at the Wardens to cover his escape. Fortunately everyone he’d shot had shrunk back to normal afterwards, unharmed if a little shaken and in the need of new clothes.

“All finished,” said Tom, returning to his chair. “Have a good day sir.”

“You too,” I said, toasting him with my coffee.

My steps were almost silent as I walked across the polished marble floors into the labyrinth of Pymm Technics, the lights coming on one by one to illuminate my way. I had become used to walking into an all but deserted facility ever since I’d been assigned to work with Dr Garner who insisted on working these ridiculous hours. He was the earliest of birds and could only work so early in the morning it could be mistaken for the previous night. Because he was the project lead it was my sleep schedule that had to be fucked up, one that would take me months to get back to normal.

ID badge still in hand I swiped it through the card reader and punched in the code to the lab door and waited for the heavy click before opening it.

“I need those samples,” was the gruff greeting I received before I’d got more than one foot in the lab.

“Coming right up” I said, far too use to this behaviour to take it personal.

I set my coffee down at my desk and slipped my coat onto the chair back. I then donned my gloves and got to work. I could hear Dr Garner moving around on the other side of the lab, able to visualise him scurrying from his standing desk to the sequencer on the opposite side. He would remove his glasses to chew on the arms while he read his notes and then put them back on again to read from the screen. Our deadline was fast approaching and we needed some good results or risk losing funding.

Once I had the samples ready, I brought them over to him. He took them without comment which I took as a compliment.

“They’re are progressing well,” he said after he’d inspected them all. “I’m seeing 13% increase in all samples.”

“That’s good isn’t it?”

“Only 2% better than last time,” Garner grunted. “Not enough with our review coming up.”

Before I could offer any words of encouragement, the sound of the lab lock slamming open drew our attention. We both looked over to see Tom the security guard opening the door for a man in a suit. All I noticed of the man was the vibrant green of his suit, my attention snagged on Tom.

Now Tom may have once had a body of peek physique but time had softened his middle almost as much as it had thinned his hair. I was used to seeing the button of his shirt straining over his belly, now however they seemed to be pulled taunt over his chest. His expression was glazed over, mouth opening and closing while his eyes blinked lazily, unable to focus on anything for long, continuously returning to the man in green.

Standing next to Tom, the man looked short, maybe standing at 5’6” and whip thin compared to the guard’s width. He carried a garish cane with a spherical grip he kept caressing as he looked over his shaded glasses to study the lab.

“Forgive my intrusion,” he drawled, slamming his cane on the ground with a sharp crack. “I’m hoping this is the office of Dr Gordon Garner?”

“Yes?” Garner’s response was hesitant. He was focused solely on the man in green, not seeming to have given Tom a second glance. Maybe it was just me unable to stop staring at the (to me) obvious physical differences our regular night guard had gone through. His black trousers hugged his quads, the cuffs of his sleeves were riding up his wrists and bunched where biceps met forearm. There was also an abundance of biceps there that hadn’t been when I walked past him a few hours ago. “Are you…one of the investors? Our presentation isn’t for a few weeks yet. I’m afraid you’ll have to wait until then. I don’t discuss my work without an NDA—”

The man in green just laughed. “Oh, no I’m not an investor. I am invested in your work but have no intention of paying for it.”

Dr Garner seemed to stall at this. “I’m afraid I don’t understand.”

“My apologies, I thought it was quite clear. I’m here to steal your research.”

Shock dropped Garner’s jaw for a beat but he rallied round quick and his cheeks began to flush with rage. “How dare you?! You,” he gestured at Tom, never having learned his name, “do your job! Remove him from my lab at once!”

During the exchange I hadn’t seen any change in Tom’s expression. He would simply stare at the floor, eyes lifting momentarily when the green man spoke but when it was clear he wasn’t the target audience his gaze lowered again. Every now and then he’d fidget though, one hand rising to adjust his crotch or fumble at his tight sleeves, as though trying to resolve some discomfort. He was pawing at his crotch when Garner yelled at him. The words didn’t seem to reach him. When his hand came away, I was almost certain I could see an above average erection travelling down his right leg, throbbing clearly against the material.

“And here I was hoping this wouldn’t get violent,” the man in green sighed. He opened his blazer and withdrew a gun coloured a hideous vibrant neon green and brandished it at Garner and I. “I don’t have time to dally about now. Give me your research or I shoot your assistant and make him make you.”

“Oh shit,” I breathed, finally realising who was robbing us.

The man in green’s eyes lit up over the rim of his glasses, smile broadening at my recognition. “Your assistant seems quicker on the uptake doctor. Perhaps you’d like to enlighten him as to who I am?”

“Guard!” Garner bellowed. “I order you to apprehend this madman!” He then spun on me. “Is this some kind of joke? Who is he, and why does he say you know him?”

“Well… if I’m not mistaken… this is the Body Builder.”

Garner snorted derisively. “Oh please! You have more muscle than him.”

“Rude,” said the Body Builder. “I grant you, maybe I should have chosen a better name for myself, but I find it fits so well with what I do. Perhaps I need to demonstrate.” Slowly he turned the gun on to Tom, aiming for his thigh. Tom’s clouded eyes followed the gun until it stopped moving and then lost interest again. “I only gave him a mild dose to keep his services for longer, but if this will step things up…”

There was a hiss of air as the Body Builder pulled the trigger. Tom gave a low grunt, head dropping to stare at the dart sticking out of his thigh. Curiosity got the better of me and I found myself staring in anticipation rather than running away.

Tom’s thigh began to inflate and ripple under his trousers. It shuddered and swelled, the dart getting dislodged to clatter on the floor. The growth spread outwards, Tom’s trousers getting tighter and tighter, the heads of muscle swelling out and becoming clearer. I could see his dick throb and thicken as well, earning a grunt of discomfort and possibly pleasure from the growing guard. The cuffs of his trousers began to rise and I could see his shoes begin to swell and creak as his feet grew too. His belly began to recede, the mass seeming to move upwards and spread across his chest. He moaned again, straightening up as he appeared to get taller, spreading his arms out as lats stretched out. His pecs ballooned against his dark blue shirt, pulling at the buttons to give a glimpse of his hairy chest. The collar was the first to go as his neck thickened with a deepening growl coming from it. Traps rose up and delts stretched out his frame even more.

Tom’s glazed expression had quickly evolved into one of rapture and awe; his eyes drank in his growing form, watching himself bring an arm up and flex until the sleeve burst off, his chest sending two more buttons flying as they broke free. His shoes came apart with a pop, inseams of his trousers splitting open. The tails of his shirt fluttered around his narrow, chiselled waist, several inches from the waist band which while too wide for his core was struggling over the swell of his quads, glutes and crotch. And speaking of crotch… a wet patch was spreading out from the flaring, clearly defined mushroom head pushing against his trousers, moments before the monster sprang free in a flurry of tattered trousers and spatters of cum. Tom gave a below of relief, feeling his pecs, tugging the strips of shirt off of his arms as they cut into him.

I had to admit I was rock hard myself. I’d always like muscular men and to see Tom swell up to this Titan was pushing buttons I hadn’t known I had. He’d only grown to about 6’11” but his frame was immense. I struggled to think how much muscle he’d packed on, his heaving shoulders easily wider than the door behind him. He looked all the more massive standing next to the diminutive form of the Body Builder, who had pulled out a tissue to wipe off a few splatters of cum from his shoulder.

“Should have known he’d be a gusher” he muttered to himself. “Now, I’m on an ever tighter schedule because of that demonstration so give me your research now or my henchman will break your assistant like a toy. No offence,” he added, giving me a sparing glance. The Body Builder’s posture suddenly stiffened. “Shit.”

With surprising agility, he leapt forward just as a dark figure flew through the wall behind him like a ghost, landing on the spot the man in green had stood moments before. Tom reacted with an immediate swing of his powerful arm, striking the figure and knocking him clear across the room into the empty fridge hard enough to shatter the glass in the door. My scrambling brain tried to discern how this figure had managed to pass through a wall like it wasn’t even there but then take a hit from the pumped up Tom, dent a reinforced fridge and still stand on his own feet. Then I took in the outfit and realisation struck.

“Density,” I breathed.

The real life superhero was in our lab, rolling his bulky shoulder as shards of glass fell off him. His suit was skin tight, showing off every bump, curve and crease of his muscular form. The majority of his suit was a shiny black, with swaths of dark purple running over his chest and shoulders, bands running over the crooks of his elbows and patches on his quads. He also wore a pair or speedos of the same colour. He brought his gloved hand to massage his smooth, chiseled jaw, his black mask over his eyes somehow whiting them out so it was impossible to tell where he was looking. His skin was a dark caramel, hair darker than his suit and swept back to show off his sturdy, furrowed brow.

Despite the situation, I couldn’t help but find myself thinking, not only was he hotter in person, but bigger as well. The stomp of his boots. The way his quads rippled as he shifted his weight was clear to see beneath his suit, he may as well have been naked. Suffice to say, I had the hots for the hero, as the collection of pictures taking up a folder in my phone I would often peruse while waiting on test results in the lab, pulled into my desk to hide my hard-on. Now to have him here, in the flesh, it was almost a dream come true…if not for the danger.

The Body Builder lifted his gun and fired a quick shot, but Density tensed his pecs and the dart bounced off. His power was the ability to alter his mass and density at will; able to become solid enough to stop a car or to become insubstantial enough to pass through solid objects. The hero gave a few extra cocky bounces of his thick chest as a taunt but the villain didn’t fire again. Instead he snapped his fingers.

“Deal with him,” he ordered.

Tom pounced like a jumbo tiger, his first blow meeting Density’s raised hand with the sound of 2 boulders clashing rather than flesh. I was distracted from the fight when the Body Builder spun round in a graceful arc and struck Dr Garner with his staff against his jaw. The doctor fell against me, causing me to lose my balance. I had enough sense to catch him and slowed our decent to the ground, except Garner caught his head on the edge of the counter with a sickening crack. The Body Builder bore down on us, ignoring Density and the ‘roided up henchmen he’d made of Tom.

“Research, now” he demanded simply. When Garner didn’t respond, he jabbed him in the chest with his staff. “I didn’t hit you that hard, stop faking.” After waiting a beat and the doctor still didn’t stir, he sighed in frustration and then turned on me. “Did he have a fucking glass jaw or something? What a wimp.”

Meanwhile one of the blows Density landed against Tom’s chest was so powerful it made the widows rattle. But all the security guard did was grunt and stagger back before following it with a blow of his own. The blow never landed, in fact his whole arm passed harmlessly through Density’s grinning face. The giant staggered forward, unbalanced while the hero stepped out of his back and then swung a well shaped leg to boot his butt and send him head first into the fridge.

The tip of that bloody cane tapped my chin and forced my attention back onto the Body Builder. “Ignore them and focus on yourself. Where does he keep his research files?”

I pointed to his standing desk just as Tom ripped the fridge from the wall and hurled it at Density. The hero crossed his arms in from of him and then flung them apart, the fridge frame bending and buckling even more as he deflected it to cash into the desk and smash the desk, and the computer into pieces. The tray of samples I’d compiled were launched across the room and spilled their contents over the floor in the corner.

“Of course,” the Body Builder sighed as the titans clashed behind him again. “Well, plan B, you’re going to cart the doc out of here so when he wakes up, he can tell me what he knows.”

“No!” I cried, feeling like a deer in the headlights as the villain lifted his gun and aimed it at me. His angular face twisted in a sneer as he pulled the trigger.

Just as he fired, Density hurled a beaker past Tom’s bulk and struck the Body Builder on his shoulder. I heard the gun go off, flinched and frantically searched myself for the dart but felt nothing. It must have missed.

Meanwhile, when Tom twisted to inspect what had caused his master’s distress, Density closed one hand over the other, lifted them both overhead and brought them down swiftly into the back of Tom’s head. The swollen security guard’s eyes lost focus and he tottered to one side. Density quickly followed him with a kick to one of his knees and when Tom toppled forward, Density’s fist was already swinging up to meet it. The force of the blow shook the windows again as Tom was lifted off his feet a few inches and fell back, sprawling across my desk for a beat before it buckled and broke under his weight.

“Fuck,” grumbled the Body Builder, more disgruntled than angry. He eyed me and then Garner’s unconscious form and then finally Tom sprawled out on the lab floor. “Fuck.”

Density, slightly winded from his battle made his slow way to the villain, heavy booted feet crunching glass and plastic debris that littered the floor. “Back up is on the way,” he panted, chest heaving beneath his suit. “Surrender peacefully or—”

“No thanks” snorted the Body Builder and lifted the gun again as he lunged for me. He grabbed me by the shoulder and hauled me up with surprising strength. Dr Garner rolled off my lap, face hitting the floor. Density was already charging towards us, hands outstretched to grab the gun. It went off, I saw it bounce off of his chest again, saw it ricocheted back towards the Body Builder, skim past his arm just before I felt it pierce my neck.

I felt a flush of heat spread from my throat, then the world spun as Density crashed into me, wrenching me from the Body Builder’s grasp and sending us stumbling into the corner of the lab. I felt the bite of glass against my back while the front was getting smothered by the lycra costumed expanse of a superhero’s pecs. Well, if I was going to die at least I would be happy.

Density’s strong arms cradled me as he set me in the recovery position and then hurried after the fleeing figure of the Body Builder. I remembered seeing his purple clad backside swaying before me as he ran, dreamily wishing I could have a piece of that cake.

I’m not sure how much time passed, while I laid there on the floor, still feeling a pulsing heat in my throat coupled with a spreading chill running through my hands like icy pins and needles. I was vaguely aware I was in a puddle of something but couldn’t find the will to move.

“He’s gone,” I heard Density saying, “took off through the window and had one of his hover scooter things waiting.” There was a pause and then he continued aggressively, “Well Icarus had better get his feathered backside moving then! I held him for as long as I could, it shouldn’t have taken them this long to get here.” Another pause. “Just the one. He’s knocked out so should shrink back down soon. I’ve two injured civilians as well in need of medical attention.”

My vision went dark. For a moment I thought I was passing out, until I noticed the purple speedos containing a hefty basket. Density had come to check on me, squatting down with his legs spread. I quickly pulled my gaze away and pushed myself up off the floor.

“Easy there sir,” he said, a supportive hand coming up to help me rise gently. “It’s all right, he’s gone now and medical help is on the way. Can you tell me your name?”

“It’s Steve, and thank you” I said, grateful my words weren’t slurred despite how foggy my head felt. I reached up to rub my neck and brushed the dart out. It fell to the floor with an accusing clatter and I heard Density inhale sharply.

“You got hit” he stated. His white eyes gave nothing away but I think there was a pucker of concern on his lips. He had nice lips, full and just begging for a kiss. This close I could see the fine shadow of stubble starting to grow through.

“Yeah, I saw it bounce off of you and hit me,” I said, touching the hot patch of skin the dart had pierced. The silence that rang from the hero made me rethink my choice of words. “It was an accident, I know, you were trying to save me, I don’t blame y—”

“Why haven’t you grown?” he asked, cutting me off. “His formula is normally nigh instantaneous. How do you feel?”

“Like that Katy Perry song. I’m hot then I’m cold…” I trailed off as I took in more of the hero’s frame. His suit hugged him incredibly well, it was honestly like it was painted on, how tightly it clung to him and showed off every striation of muscle. The speedo was the only part that had enough extra room to leave some mystery. I could see it sag with the weight of the package but there was no visible penis line. “Feeling very hot now.”

I shifted off my hip to sit on my backside, spreading my legs and resting against the wall. I was now shamelessly staring at Density’s body, groping my crotch as I started to get hard. I wanted so bad to reach out and get a handful of those purple pecs, to see what the material felt like, and just how firm his muscles were. I lifted my gaze up that thick neck, seeing the hero bite his lower lip, brow furrowing slightly. There was a twitch from my groin as it pushed against my hand. Suddenly my trousers and underwear were feeling tight.

“What’s…what’s happening?” I asked, a small part of me rising above the horny cloud that had enveloped me. “Why does my dick feel…”

Density and I both looked down. My crotch was twitching and swelling, it had ballooned into an orange sized bulge, considerably bigger than it should have been, and with a start I watched it jump and swell bigger. I could see my balls growing larger, lifting up a thickening, plumping dick to push against the fabric of my trousers. I could feel my cock sliding across my thigh, feeling I was just chubbing up into an erection but it had already surpassed what used to be my full size.

“It’s… it’s just your dick growing,” breathed Density. “I’ve never known his formula to do that.”

“Why is it getting so big?” I asked, trying to stay calm as my package continued to swell, the confines of my clothes becoming restricting, moving from uncomfortable towards painful. “Seriously, how big is it going to get?!”

“I don’t know. How… how big is it normally?”

“Not this big!” I snapped, grunting as the salami and plums continued to grow and grow. My shaft was a clear tube across my lap, reaching over to my left hip while my nuts were pushing against my thighs forcing me to spread them wider.

“We’d better let it out,” said Density, his large hand going for my crotch.

“W-wait!” I sputtered, but when his palm brushed my shudderingly shaft it turned into an embarrassing moan. Just that slight tough sent tingles of pleasure running along the large surface area of my cock. My eyes rolled and toes curled, I thought I was going to cum. I felt a spurt of warm liquid ooze out as Density popped my fly open and tugged on my trousers. I’d picked a pair of bright red boxer briefs, the only splash of colour in my usual black and grey underwear drawer, my cheeks going a similar colour now that such a hottie like Density was seeing them. I lifted my hips to help get my trousers down until we were both staring at my comically straining red boxers trying to contain my growing cock.

There was a hesitancy in the way Density held his hand over my groin, hovering there for a beat before he pulled on the waistband. As though sensing a way out, my cock made a break for freedom, the head shiny with pre, leaving a trail as it slid up to my navel but continued to stretch higher up my stomach. My jaw dropped and I spread my legs, feeling my nuts flop down with a bouncy jiggle. My dick throbbed, still steadily getting bigger, thickening into a coke can cock but promising to get even bigger.

I vaguely heard Tom moan, caught a glimpse in my periphery of him starting to shrink down, but Density only had eyes for the monster of a dick attached to my groin. The hero changed his position, knees going to the floor and resting on his haunches.

“I… I…” he stammered. “Fuck, that is a big dick.”

In response my dick throbbed and swelled a little bit more. Hesitancy tightening his burly shoulders, the hero reached out for my shaft again. He brushed it with his fingers, causing my stomach to flip and making me bite my lip to keep from crying out again. The head flared and oozed a heavy stream of pre onto my shirt, but I didn’t care. Density licked his lips. His hand rested against my shaft, fingers trying to encircle it but finding he couldn’t get his grip all the way around.

“So thick,” he breathed, and then gave a wheeze of a laugh, grinning, “I can feel it pushing against my fingers. It’s still getting bigger.”

I saw his Adam’s Apple bob as he swallowed, again his tongue slipping out to wet his lips. I began to wonder what it would feel like to have those luscious lips wrap around the head of my massive dick. What would it feel like to have his tongue roll over the glands. Density started to lean forward.

“Density!” a sharp voice cracked the moment like a rock through a window. It echoed down the corridor and into the lab and snapped us both out of our stupor. “Where’s the injured civilians?!”

“In here” Density called back, his voice hoarse. He quickly rose to his feet, and I saw his purple speedos tenting over his impressive erection. Well, it was impressive to my normal standards before my cock grew well into double digits. He quickly tried to adjust himself to make the tent less obvious, hunching over to bring his hips in while vigorously rubbing his forearm to try and redirect the blood flow. “We’ve got a bit of a situation,” he called again before a man and woman carrying medical gear came into the lab.

I expected the pair of them to stop and gape at me, but I got the briefest of glances before they descended onto Tom first of all. The man withdrew a blanket that looked like it was made of tin foil, draping it over the guard’s lower body while the woman opened Tom’s eyes to check his pupils and then felt the pulse at his neck. The pair worked like a well-oiled machine; he sprayed something onto Tom’s chest while she prepped a needle, jabbing it in as soon as he’d wiped the skin down. They then began collecting samples, in what I’m not entirely sure was legal without Tom’s consent. The guard was in no position to comment though, still away with the fairies while he was swabbed and checked.

“He’s stable, he’ll be fine,” said the woman. “Best to give him an overnight stay at St Margaret’s just in case but looks like it’s left his system already.”

Then the pair turned their attention to Dr Garner. I’ll admit to feeling a little hurt. I mean, granted I was conscious and perhaps the other two did take priority with possible head trauma, but come on! I was sat there with a dick that had grown to maybe almost two feet with my nuts filling my bright red underwear like I was smuggling a paid of grapefruits in them. Surely I should have garnered a bit of attention? That was when I realised that since their entrance and my distraction, my dick had stopped growing. I snuck a glance over at Density and saw his erection had settled but he was doing his best to look anywhere but at me.

“We’re going to need an ambulance for this one,” the woman said, waving her torch over Garner’s eyes. She pressed the radio on her shoulder and then barked off a series of instructions while her partner checked Garner’s air waves and attached a mask over his face. “Did you say this one was the target?” the woman asked, breaking her string of instructions to fire the question at Density.

“Yeah,” the hero grunted, voice still sounding a little strained. “He was after the doctor’s work but wasn’t successful.”

“Probably best to take him to a secure location” she said before relaying the same thing to the person on the other end of the radio. All she got was a crackly “Copy” in response before she rose up and approached me.

I did not like the way she stood over me, staring at my exposed penis. Despite its size I actually felt it almost shrivel up under that cold grey stare. I was beginning to wish they’d focus on Tom and Garner again.

“Hmph,” she grunted. “Haven’t seen his serum do that before. I assume it wasn’t like that before you got shot?”

I shook my head.

“How big was it before?”

My cock was definitely softening now as with a rush of heat I felt like all the blood in my body was marching to my cheeks. “Erm…about…S-ss-six inches.”

“Hmm, so we’re looking at a 250% increase at a guess. I don’t see any unhealthy swelling or threatening growths, it looks to be just a healthy penis. Admittedly a quite impressively large one. Well, have to run some tests, just to make sure everything is all right. Think you can get it back in your trousers or do you want a blanket?”

“Can I have both?”

“Sure,” she said matter-of-factly. “I’ll arrange transport to Eugene Labs and they’ll—”

“No!” Density blurted, then coughed and covered his mouth. “I mean it would probably be best if he came back to base… for protection and… observation.”

“Why?” asked the woman, her voice dropping a few degrees. It didn’t look like she was used to being contradicted.

“Watcher will want to take a look at him, and his lab equipment will be better than what they have at Eugene Labs.”

“But Watcher isn’t technically a medical Doctor.”

“He can do all the fancy scans anyone would ask for in a blink. Besides he’s the one leading the charge to break the Body Builder’s formula, he’d want to get first look at someone that erm… reacted… like this.”

The woman frowned hard at the hero who despite his greater size and stature seemed to shuffle awkwardly like a little boy caught doing something he knew he shouldn’t. Her icy glare thawed however and she sighed. “It’s your call, on your head be it. But if he’s coming to base we need to bag him.”

The trip to the mysterious base was a disorientating one. Once I’d stuffed my soft, yet still quite larger dick into the leg of my trousers and wrapped myself in their foil blanket, I was escorted to a sturdy looking 4x4, bundled into the back where a black sack was draped over my head. I’d never been car sick before, but without a point of reference every slight turn felt like we’re were hitting every roundabout and doing the loop 3 times. I was relieved when we got to a stop, felt Density’s strong hands help me down from the 4x4, it was however short lived when he stopped me from removing the hood and instead I was put into a different car. I was very aware of Density sitting beside me, the car being much smaller than the 4x4, and the proximity causing my cock to chub up uncomfortably.

There was also the strange sensation in my balls. They felt very sensitive, I could feel the vibrations of the car and it was causing a tingling sensation…which was quite pleasant honestly. I really wanted to touch them, part to try and find a comfortable position and the other just to rub them. They were begging for attention. They felt so full, and tight, like I was a horny teen again that needed to get off just to relieve some of the pressure.

“Are you okay?” Density’s voice was a soft rumble, shoulder bumping mine as I imagine he lowered his head to my ear.

“Yeah,” I said, my voice coming out strained until I cleared my throat. “Everything’s just… tighter than I’m used to.”

“I’ll say.” There was a pause, hanging heavy in the air. “Do…do you need any—”

I flinched when I felt his hand on my lap, started by the sudden contact. Density seemed to pull away from me as much as the car would allow and didn’t speak again until we arrived.

The bag stayed on as I was hustled and jostled about, gripping my blanket tightly around my waist, waddling awkwardly with my cock down one leg. It was a weird sensation, not comfortable in the slightest, yet the constant rubbing was causing blood to flow into the shaft, making it hard, and therefore harder to walk. Mercifully before long they ushered me into a room and the hood was removed.

I blinked against the sudden light, blinded by what felt like over an hour of darkness. I had to blink a few times to get my eyes to work, to take in my surroundings. I’d expected a laboratory, but it looked more like accommodations, like someone’s living room. It was very Spartan, with hardly any decoration and lacked the warmth of it actually being lived in. I’d been placed on a sturdy armchair, the arms and back rest all one curved piece making me feel like I was in a cup. I was still clutching my foil blanket, but my nuts were feeling mashed in me trousers and I wanted nothing more than to let them out to breath.

“I thought it best to wait here,” said Density, standing on the opposite side of the room, arms crossed causing his purple pecs to bulge and rub against his tight, toned arms. His thick legs were placed firmly apart, like he was ready to lurch into action at the slightest need. Whether it was to lunge towards me or away was unclear. “Watcher and Icarus are still out and rather than wait in the lab I thought… my room might be more comfortable.”

“You live here?” I asked.

A shrug of his shoulders. “Sometimes. When there’s a crisis on or there’s a threat and I need to be close to the action. I have my own place out in the city, that’s where I spend most of my nights when I’m not fighting crime.”

“Cool,” I said, mentally kicking myself as soon as the words left my mouth. People only say cool when they have nothing to say. “Have they caught up with the Body Builder yet?”

“I’m afraid he gave us the slip,” sighed the hero. “But don’t worry, we’ll find a solution for your… pre-dick-ament. How… how does it feel?”

“Right now it feels uncomfortable.” My balls were feeling as tight and full as ever, warm against my inner thigh. It was almost like I had two warm water balloons sloshing about.

“Did you want to… take your trousers… off?” I clutched the blanket tighter. “Just because, I mean, if it’s uncomfortable for you, having it all packed in like that, you can… let it out.”

While he did have a point, there was a small flicker of dignity I was desperately trying to keep hold of. Take my clothes off in front of this hot specimen in spandex? Normally when I got my meat out it was to a picture of him, I was afraid what would happen if I took it out again with the real thing before me. Would the Pavlovian dog rise up and beg for attention? Unfortunately the feeling of discomfort was steadily chipping away at my resolve.

I stood up, releasing my death grip on the blanket and letting it fall to the floor. I could only guess from the tilt of Density’s head, his white eyes betraying nothing, that his gaze had dropped to my groin. I too took a moment to appreciate the thick bulge of my shaft running down one leg, the swell of my nut sack pushing out and weighing my waistband down. I unbuttoned my trousers, stepping out of my shoes as I did. The sensation of my crotch bouncing off my legs, swaying heavily with my movements was a heady, confident boosting experience. I heard Density clear his throat when the head of my cock, which had slithered out of the leg of my boxers, came into view as my trousers pooled at my feet. I stepped out of them, and thinking I’d gone this far, may as well go all the way.

There was another strange, strangled noise from Density as I took my boxers off. It was as though he was about to tell me to stop and nearly bit through his tongue to stop himself. I was distracted by the relief I felt as I shoved my boxers down and my junk swung free. Fuck, it had been so tight in there! My dick flopped about, there just seemed to be soo much of it. Even rested atop my tight balls the head was nearly down to my knees. Had it been growing steadily this whole time still?

I must have been staring so intently at my dick, I didn’t notice Density approaching until I saw the purple of his speedos come into view beside my swollen flesh. I could see his erection tenting the material again. My own dick twitched, a strange feeling of…I don’t know what, pride, smugness, sexual prowess, flooded through me at the difference in size. He had more muscle in one leg than I did in my whole body, but my soft dick could dwarf his hard one with ease.

I lifted my head, he looked taller up close, and looked into his handsome face, his caramel skin begging to be touched, full lips parted slightly. I could feel his eyes on me, even if I couldn’t see them. I wondered what they looked like, what colour they would be. I wanted to see them. Slowly, I lifted my hand towards his face.

Density’s face came down to mine. He pulled me close and kissed me. He’d misread my attempt to unmask him as a desire to kiss him, and believe me, I was not complaining. I gripped onto his solid, broad shoulders, digging my fingers into the hard heads of muscle as his thick tongue probed my mouth. His strong hands fisted in my shirt, steel like arms encircling me and pressing me into his rock hard, pumped body. My fingers were flying over his traps and back, feeling all that muscle rippling beneath the tight spandex. Fuck he was ripped.

Just as suddenly as he’d started, Density pulled his head back and the kiss broke. My racing heart tripped over itself, lungs gasping for air as I wondered what I’d done wrong. Was I a bad kisser? Had I used too much tongue? Not enough? Density wasn’t looking at me though, his head was down and the hands on my shoulders began to push me back.

“I’m sorry,” I started, until I felt it.

I looked down to see the cause of Density’s change in attitude. My dick had chubbed up, rising to slide between the hero’s powerful thighs and lift his own crotch which rested atop my shaft. I could feel my dick throbbing still, getting thicker and harder and realised it was only a semi. Wordlessly, Density lifted his leg to let my dick out. We both watched as it rose up steadily, past his crotch, up his abs, the head just stopping at the underside of his purple pecs. It poked against them and a large bead of pre oozed out.

“Holy shit,” he breathed.

I was in awe too. Because of the height difference, my cock measured further up my chest. I could probably lean forward and kiss the head if I wanted too. The swollen head looked like it would be a mouthful too.

“That’s so hot,” Density said, voice a low, breathy rumble. He was going to grab it, I could see the need in his face, and fuck, did I need him to touch it too.

A shrill beeping shattered the peace and the moment. I saw something flashing on the hero’s wrist.

“For fuck’s sake!” he all but roared, clamping his mouth shut and swallowing hard before activating what I assumed to be earpiece. “Go” he said sharply, his hand catching my wrist to keep me in place in case I’d thought his ire was directed at. His face fell. “But sir I—…Yes it was my call but—… we followed proce—… I felt it was a necessary ri—.” He gave up trying to speak and instead grunted “Affirmative” at regular intervals. Finally he signed off and then grabbed my face and pulled me into a kiss.

“I’m sorry this keeps happening,” he said in a low whisper. “I swear the universe is actively against me on this. Please know that I’m not trying to jerk you around or anything, I will be back, I just have to get my bollocks handed to me, and then I’ll be back to help with yours. I promise.”

And with that he gave me another kiss, this one more gentle and marched out of the room, his gait somewhat stiff. I watched his pert backside vanish around the corner and heard a door open before silence fell and I was left alone.

My cock throbbed, almost angrily at being denied attention yet again. My balls felt like they were actively punishing me for getting riled up but with no release again. I let out a grunt as they physically shuddered and dropped lower, swelling bigger against my legs. I staggered back, cock swaying in the air and my massive nuts bouncing too until I gripped the back of the armchair for support. I swear I could hear the cum sloshing inside my balls as the grew bigger and bigger. It was like all this horny energy was making them produce it, forcing them to swell to accommodate it all. And fuck they were feeling full.

“Wow, no wonder Power Bottom was so desperate to bring you inside.”

I spun and nearly fell over when the weight of my nuts trailing behind shifted my centre of gravity. My cock waved in front of me and I fumbled to push it down with one hand while the other reached for the silver blanket. I tried to cover my hardon as best I could, but the monster kept pushing itself back up, refusing to go down. I just stood there with a tin foil tent dangling before me.

The intruder giggled at me. He was long and lanky, but with well shaped bulges along those long limbs in all the right places. He was in a super suit, a vibrant blue with gloves and boots a darker shade. It had a plunging neckline to show off a set of shapely, pale pecs, and a belt cinched tightly around his waist. It had a large round buckle with a sideways figure 8 like an infinite symbol. It was warped however, designed to look like a rubber band looping around itself.

With a start I realised this was Expando, another member of the Watcher’s heroic squad. His body was essentially like rubber, and he could stretch and expand himself to near limitless dimensions. He normally had an overhead mask on, but right now his face was bare. I’d only ever seen him with that blue cap on his head, but now I could see his tousled curls, straddling the boundaries of brown and blonde to the point I could quite decide which it was. He had a pointed chin with a little dimple. And he was grinning as fair blue eyes shamelessly roved over me.

“I know,” he said, pulling a mock embarrassed face, “you’ve seen my face without my mask on. Secret identify ruined, on no! But, I think I can trust you to keep this quiet, right?” He lowered his head to look at me through his lashes, bringing a finger to his puckered lips to tap them.

When I didn’t respond he moved his hand to pinch his chin in thought, looking me up and down again. Casually he lifted the blanket to peek at my cock, which was refusing to go down and still stood out as hard as steel. He gave a low whistle. “Some people get the best lab accidents.”

“What?” I sputtered.

Expando let the blanket fall and focused on my face, smirking wickedly. “Just a bit of hero humour, Super Dick. You know, the whole origin of powers coming from lab accidents thing. Bet there would be plenty of guys wishing they could get results like this! So, what were you working on? Some sort of steroid Viagra? Or are you the one that keeps sending me those emails about how you can improve my penis size?”

“What? No!”

“Okay, clearly I’m not doing a very good job at relaxing you with humour,” Expando chuckled. “You’re just so tense, I’m just trying to help you relax. Here, will this make you feel better?”

The blue clad hero reached down and undid his belt. It had always been a thought at the back of my mind when it came to superhero suits if they were just a big Lycra onesie or a two-piece made to look like one. When Expando opened his belt I could see at least in his case it was the latter. Another question I’d often thought but never voice was about to be answered. Do superheroes wear underwear?

For Expando, the answer was no.

The rubberised hero rolled the lycra trousers down and pulled his cock out. He’d been completely commando in his suit, and his shaft was already rock hard as he stroked it in his gloved hand. It was a veiny, sturdy uncut 7 incher he was fondling with low hanging balls he let swing between his legs.

“There we go,” he said, still flashing his bright teeth in a cheeky smile, “now both our dicks are out! Well, mostly…”

Expando tugged on the silver blanket and I let out a spluttering moan as the material rubbed my achingly sensitive head. The blanket fell away and my dick bounced up, free from what little weight it had on my still solid shaft. The sensation ran down my dick, pooling in my balls and making them swell against my legs, pushing and forcing me to widen my stance. Expando didn’t seem to notice, he was too busy staring at my exposed dick.

“Super Dick, indeed,” he chuckled darkly. He was rubbing his cock, slowly now as he looked it over. “You know, Density always seems to think he’s the big, nice guy, but looking at this,” he ran a finger up my shaft, catching the trickle of pre that had oozed out, “looks like he’s been giving you a bad case of blue balls. And with balls as big as yours, I bet that can’t be comfortable.”

“It really isn’t,” I panted, my cock and balls aching for a release. My fucking balls felt like they were going to burst they were so full of cum. Seeing Expando shamelessly stroking himself was making me just want to grab mine in both hands and go to town. It would be a two handed job for sure.

“Want me to help?”

“What?” I gasped, struggling to think straight. “What do you mean help?”

“Well,” he said slowly, stepping even closer, my cock bobbing inches away from his chest, “I am a hero after all, and you clearly look to be in distress. And what is it heroes do? Help. Those. In. NEEEEED.”

He lowered his head and took my cock head in his mouth. The sensation of his hot breath rolling over my sensitive head was like nothing I’d ever felt before. It was so intense. And then when his tongue touched my flesh I swear I could feel every one of his tastebuds dancing over my nerves. His lips tightened in a seal over it and his cheeks caved in as he sucked at it. My knees turned to water and I almost collapsed. I heard something creaking, like balloons rubbing together or something, and then felt Expando’s arms quite literally wrap around me. He eased me into the arm chair gently and then withdrew his arms. I felt my bulbous nuts bump against the base of the chair, the hyper sensitivity letting me feel every fibre tickle my sack. I writhed in the chair, loosing utter control as my body forgot how to work, my brain forgot how to think.

Expando was on his knees in front of me, close enough that my nuts rested on his thighs as he expertly worked my shaft. His hands ran up and down the length, rubbing, squeezing and pumping it while his mouth focused solely on the head. I felt his hands stretch to better grip my thick cock, larger hands succeeding in encircling its girth and squeezing it harder. My head was spinning, I was gasping and panting for air as I had what was perhaps the best blow job I’d ever had.

After all these false starts, of getting wound up into a frenzy and then being left hanging all day, I didn’t last very long. My toes curled in their socks and I gripped the arms of the chair as my huge balls clenched and I felt the cum erupt. I closed my eyes as my vision blurred, heart tripping at the intensity of my orgasm, the flood gates well and truly opened as my cum factory balls emptied themselves with glee. I could feel Expando’s lips still round my cock, hands holding tight as he swallowed it all down.

Time lost all meaning, each shot felt like both an eternity and a fleeting second I couldn’t hold onto. I managed to claw myself back into some semblance of control, enough to open my eyes and see that my cock was shrinking. Expando was following it down as it retreated back into my body, mouth taking more of my cock the more manageable it became. Below I could see my balls were getting smaller as well, now no longer so full of cum they could return to a more normal size.

But the smaller my balls got, the bigger Expando’s belly was getting. While he still sucked and worked at my cock, I could see his belly filling up with my cum. His once flat, toned core was filling up like a blue water balloon. It bounced and jiggled as he dropped down lower, his own cock poking at its underside.

Finally my balls ran dry and Expando released my cock with a wet pop and a deep gasp of air. Strings of my jizz still stretched between his lips as he gulped in air, trembling tongue coated in thick cream darting out to lick the remnants from his lips. He leant back, falling onto his butt and sprawling against the low coffee table behind him, resting against it and having to spread his legs to accommodate his bloated belly. I couldn’t take my eyes off of it, the size of it, the way it jiggled with his movements and rippled with his breaths.

“Wow,” he gasped, rubbing his jaw and wiping his chin with the back of his hand. “Wow wow wow. That was a lot of cum, Super Dick. Fuck me,” he laughed, grabbing his cum belly in both hands and feeling it. “Look at this! Hahah!” he jiggled it and caressed it gently. “It looks like that time I swallowed a basketball. It was a dare, don’t ask. And hey, look, this must be your alter ego, Bruce Wang.”

Managing to pull my eyes off of the belly I’d given the giddy superhero, I looked down at my cock. It poked out from the tails of my shirt, shiny with Expando’s saliva and my cum, no longer the monster it was but still bigger than my usual. It was about 8 inches, slowly softening to 6 which had been my max when hard. My balls were no longer grapefruits and resting on the edge of the chair rather than hanging off like they’d been before. I was relieved. Having a big dick sounded all well and good but that had been a bit too big for comfort.

“What the ever-loving fuck!”

“Oh shit,” mumbled Expando, covering his mouth as he burped discreetly and tried to roll onto his feet and pull his trousers up at the same time. “Hey Density!”

Density was standing by the entry way, lips curled back and teeth bared. The tendons in his neck were taunt and rigid. He looked like pissed off personified. Watching Expando wobble onto his feet and struggle to do his belt over his cum gut didn’t cool the purple hero’s temper. In fact it looked more like it was adding fuel to the fire.

“No need to thank me,” Expando said, giving up on his belt and leaving it open. He had at least put his dick away. “I’ve managed to help your little friend here. Turns out he was just pent up!”

Density marched into the room, bearing down on the bloated hero who scuttled back until his claves caught the table, trapping him.

“You grassed on me!” Density growled, looming over Expando, muscles straining against his suit. “You told the Board I brought Steve on site because you knew they would haul me out to tear me a new one so you could slither in here!”

Expando pulled a face, twisting his mouth and quirking his eyebrow in mock confusion. “Huh? Me? Why would I do something like that? I mean, you brought a civilian onto the premises without authorisation, and then left him alone. Should I have kept it quiet? Should I have left him here unsupervised? That wouldn’t be very safe now would it?”

I could feel anger coming off of Density in waves. I discretely pulled at my shirt and crossed my legs, trying to hide my nakedness. The movement caught Density’s attention though and his head spun on me so quick I was surprised he didn’t get whiplash. His stare practically struck me and pined me to my chair. Seeing my startled expression was like a water bomb on his fiery rage and the tension left him instantly.

“I’m so sorry about this” he said and then added through gritted teeth, “he’s right. I should have done things better, and I shouldn’t have left you. And for that I’m sorry.”

“Good, well now that’s settled I’ll just—”

Expando had stretched one of his legs around Density in an attempt to step past him, but the larger hero stopped him with a solid hand to the chest. The stretched leg snapped back to normal as Density encroached further on Expando’s space. He jabbed a finger at the cum belly between them. “The apology was for him, as for you, I’ll deal with you later.”

“Promises, promises,” quipped Expando, though there was a slight waver in his voice. He gave Density a nod and stretched himself round the human blockade and made to leave. “I’ll see you around later Super Dick” he said, giving me a wink and tapping his finger to his head in a salute. “If those balls need emptying again, just give me a—”

His voice trailed off and he stopped in his tracks. He was looking down at his belly, hands coming up to stroke it. I could hear it gurgling from across the room. Expando gave a grunt.

“Are you okay?” I asked, standing up and moving with Density to approach the confused looking hero in blue as he turned back to face us.

“I… I don’t know,” he said, his usually buoyant voice uncharacteristically flat. “My stomach feels…weird.”

“Probably because you’re full of my spunk,” I said.

“While I admit it’s a lot of cum, I’ve seen him fill himself with a swimming pools’ worth of water” said Density. “This shouldn’t be causing you any discomfort Expando.”

“Yeah, well it is!” he snapped, just as his belly gave another load gurgle. He groaned and gripped the squishy tummy. “Ah fuck.”

Suddenly Expando’s belly began to retract. It deflated beneath his hands until his stomach was once again flat. He straightened up, blinking in confusion and running his hand searchingly over his abdomen, as though trying to find where his belly had gone. “Huh. I guess I… digested it?” He snapped his belt back together and then lifted his head to look at us, shrugging his shoulders.

Density began to say something but we both saw something happening to Expando’s chest. His firm chest was filling out, the pecs steadily bulking up within his suit, stretching the low neckline. His shoulders too were starting to thicken and grow, becoming shapelier and more sculpted.

“What are you two staring at?” he asked, his neck thickening and traps rising up like little boulders. He looked down, seeing his chest sticking out more than usual as his arms began to thicken and his biceps and triceps inflated. His eyes widened as well, but in shock rather than growth which was spreading rapidly through the rest of his body. The once lithe hero was now rapidly approaching Density’s level of bulk with no signs of slowing.

“What the fuck?” he breathed, feeling his stomach as abs popped out like little bricks, pushing out against his suit which clung to him and hugged their rising shape. The sound of stretching rubber was becoming louder as Expando continued to grow bigger and bigger.

“Expando,” said Density, “stop messing around.”

“I’m not doing this!” the growing hero squeaked shrilly, his legs rapidly thickening as the heads of his quads rose up into that seductive tear drop shape. His claves bugled and grew thicker as well and not only that but his crotch bulge was joining in on the growth as well. The front of his trousers was now drooping with the weight of his inflating package. I could see the three orbs of his cock and balls getting bigger and bigger, the shaft getting curled up and rising upwards. His quads shuddered thicker and pushed his package out even more.

Expando was becoming incredibly wide now, his whole body just so pumped up with muscle bulging everywhere I looked. His arms were as thick as footballs, pecs a dense shelf of muscles, his nipples looking fat as they poked visibly against his suit. His forearms were easily thicker than Density’s legs now, his lats pushing out against his arms to make them hang at an angle. As much as Expando was growing, it was only affecting his muscles. He wasn’t getting any taller, just amazingly buff and swole. The various muscles were staring to impeded Expando’s movements though, every muscle on his body battling it out for space, determined to take up as much room as possible.

“Oh fuck,” Expando breathed, but he didn’t sound afraid, he sounded…turned on. “Fuck yes, more, more! Keep getting bigger!”

His cock sprang out with a sudden lurch, startling Density and I into taking a step back. I could see his dick getting fatter and thicker, starting to grow a lot quicker than the rest of his body. I could see it growing against his suit which managed to stretch with the growing member and hug it like a second skin. I suppose his suit was designed to match his stretching powers so it was used to matching him no matter what he did. His balls were rapidly inflating as well, dropping down to knee level and swelling into beachballs. I watched, enamoured as his cock began to rise as he started getting hard, it was even bigger than my cock had been.

“You see that?!” Expando laughed, struggling to bend his insanely thick arms to touch his shaft, but the ample pecs bulging out and his wide lats kept his arms out and biceps and forearms were refusing to back down from each other all acted against him. “Guess I’m Super Dick now huh?” he laughed and grunted, bucking his hips to make his cock bob and sway in the air. “Although I’m surprised I can see it at all past these pecs!”

It was true, Expando’s head was almost lost within his pecs and traps, the latter rising like mountains on either side of his head, brushing his ears, while his pecs pressed against his dimpled chin. He was grinning though, eyes alive and sparkling as he struggled to take it all in, look at himself in all his swollen, muscular glory.

“Ah fuck it’s so tight! Fuck I’m so big, so full. Fuck, fuck, fffff-f-f-f-fuuuuuck!”

Expando’s entire body shook and flexed, his balls bouncing as he came. I could see his suit darken around the head of his massive cock, the cum trapped within the suit like a giant condom. With nowhere to go the splooge filled up the already fully packed crotch, the suit no longer hugging the shaft to show off every bump and crease, the layer of cum softening the edges as it sloshed and churned within.

“Oh fuck, oh fuck me!” Expando gasped. “Oh fuck that was amazing. Oh fuck, so much cum, fuuuuuck!”

Density and I were speechless. We could only stare as Expando writhed before us; a muscle blimp packed so full of massive muscles he looked like he could hardly move. And then there was his massive dick jutting out about 4 feet in front of him, and his balls approaching yoga ball size now and almost touching the floor. He had stopped growing at least but was still lost in the euphoria of his orgasm. It was a wonder he hadn’t toppled over, but I guess all that muscle made him sturdy. His breathing slowly returned to normal, pecs tensing together as he tried to get himself back under control. I could practically see the cum sloshing around his dong, probably running down to pool around his balls as well. His cute face, nestled between his traps and pecs had a goofy grin plastered across it, eyes sparkling as he looked over his body.

“So buff,” he moaned. He manage to move his arm, twisting it enough to raise the forearm, wrist bending as though he was flexing. The rest of his arm hardly moved, except the the bicep bulging even bigger, too big for him to bend. “Huh,” he laughed, “might need your guys help if it get an itchy nose. Can’t bend my arms I’m too big.” He tensed and relaxed his arms a bit and then brought them together…or at least tried too, biceps and pecs squashed together, forcing his head back as his thick chest bulged against his chin. “Even then,” he grunted, still flexing, “you’d probably have to climb up these pecs to reach my head!”

“Can’t you just stretch?” I asked, although really I’d quite happily volunteer to climb into that chest.

“Oh yeah,” Expanding chuckled, “I was so distracted my all this fucking muscle I forgot! Bet a few extra inches will give me a bit of mobility back.”

Expando lifted his arm again, finger pointing to his face. He strained and grunted, and for the first time his grin faltered. He opened his hand, shaking and flexing his fingers and then tried again. Still nothing. What little movements the muscle blimp could make were becoming more frantic and he looked in danger of toppling over.

“I can’t stretch!” he cried. “I can’t use my powers!!”

It was still incredible to see how big my cum had made Expando. He was still the same height of about 5’11”, but the width of his shoulders was greater than a door frame. Add to that the width added from his swollen arms hanging at about 45 degrees at his side made him look like wider than he was tall. If he could have walked I doubt he could have used even a double door without maybe going through it at an angle. Even then, it would take a bit of manoeuvring to direct that 4 foot penis jutting out from his hips as well.

The hotness was somewhat marred, however, by the hero’s attempts to stretch his already full body a few inches to allow movement. His pumped up arms were flailing and rubbing against his pecs and lats as the various muscle groups fought for space.

“Be careful!” snapped Density. “You’re going to fall over at this rate. And I’m not sure the floor could take it.”

Expando’s handsome face twisted into a scowl. “Don’t tell me to calm down,” he said, his suit creaking as he flexed and stuck out his dimpled chin. “Right now I bet I could put you through a wall without you needing to phase through.”

“Yeah, maybe if you fell on me.”

Expando swore and tried to take a step forward. He was hampered by… well, quite a lot at a guess. His legs were already spread to accommodate thighs thicker than Density’s chest. He would have needed more than a bodybuilder roll to get one quad over the other. If that wasn’t enough his yoga ball sized nuts resting on top of those titanic thighs made it nigh impossible to take a step forward. Yet Expando was determined to try.

His cock swung and his balls sloshed to the left as he pivoted and managed to lift his right leg. I felt the floor tremor when it landed, but I also saw the look of triumph on Expando’s face turn to one of strain as his cock and balls swung back the other way. I could see all his muscles tense and flex as he tried to hold himself up right. Instinctively I moved forward to help, going under his arm to help him find his balance.

I regretted it immediately.

His arm was so fucking heavy! His biceps alone were as big as my head, adding in the triceps and forearms it felt like a person on its own. His pecs were a strange mix of solid muscle and soft skin beneath the Lycra, his nipple rubbing against my cheek and ear as I tried with all my might to push him back up. I doubt I contributed more than maybe squashing his pec slightly, but thankfully Density came to my rescue again before I pulled something. With a grunt he first pushed with one hand on Expando’s chest and the other barely covering his biceps, then once he was off of me Density ducked in to take my place. I moved out of the way, stepping back and getting the first glimpse of the muscle blimp’s backside.

His back was like an aerial view of a mountain range; the swollen peaks and deep valleys running between them, the way they rippled and flexed as Expando wiggled his arms. His triceps were swollen horseshoes, the swell of his biceps just visible beyond them while his wide lats pushed at them too. I could probably spread my arms and just get my hands over each lat but fuck if I could manage more. And then the way that wide expanse suddenly tapered down, sweeping in to his tight waist. From the front I couldn’t see much of his core, what with his low hanging pecs and the massive cock getting pushed up by his quads and balls, from here I could see just how tight and narrow his waist still was. Then just below that his body swelled out again into the biggest backside I had ever seen. It was like a pert shelf of glutes, thick enough I could probably sit on it, each cheek easily wider than a gripping hand could cover. My still bare cock twitched beneath the tails of my shirt.

“I’m fine, I’m fine,” grumbled Expando. I could see him shuffling his feet to get them into position to better support his weight. “You can let go now.”

I realised I’d missed out on checking Density’s backside, just catching a glimpse of the purple speedo before he vanished in front of Expando. If it wasn’t for their difference in height, I would have lost sight of Density completely. As it was I could see his scowl over the ridge of Expando’s traps.

“So as I expected, you can barely walk.” Exasperated, Density ran a hand through his dark hair, leaving his arm behind his head as he struggled to think of what to do. “Even if you could walk you’d probably get wedged in the hallway, let alone fit through the door.”

“Cos I’m extra thicc,” Expando chuckled. “Bet I could give a little flex and the walls would give way for me anyway.”

“And how do you propose you could get there?”

Expando twisted his head, struggling to see over his traps to look at me. “You going to come round and join the conversation Super Dick or are you going to fuck me or something? Although unless your dick has grown again I doubt you could get past these cheeks.” Showing off his control, Expando made his butt cheeks bounce and ripple enticingly and my cock started to chub up. I tried to tuck it under my shirt, thinking I must be a sight walking around with nothing on my bottom half but my socks and my shirt barely covering my junk.

As I ducked under Expando’s arm and came back to stand in front of him, I could see his lusty eyes staring hungrily at my cock. “Did you enjoy the view?”

“Give over,” grumbled Density, but I caught him staring at my dick too.

“Don’t be jealous, I look fucking amazing.”

“You look like an over blown muscle balloon.”

“Why, thank you.”

“Aren’t you worried about your powers not working?”

Expando snorted, flexing his whole body, pecs bulging against his chin and traps swelling up around his head. “Who cares about stretching, I like this kind of expansion better! Hey Super Dick, want to be my sidekick? Just stick your cock in my mouth and make me swell up over the bad guys!”

“What? You can’t be serious,” Density scoffed incredulously, “you can’t possibly want to get any bigger!”

“Why not? It felt incredible swelling up, and just feeling my muscle rub against each other with the slightest movement is keeping me hard. And speaking of hard, have you seen my dick? What am I saying, of course you have. One, it’s too fucking big to miss and, two, you’re a size queen.”

“We need to get you out of here and down to Watcher’s lab,” said Density, ignoring the blimp’s jibes. “Steve, I’m going to take him from behind—”

“That’ll be a first” mumbled Expando.

“—if you try and keep his dick under control. Shame we can’t shove it in his mouth to keep him quiet.”

“Suppose that is the only downside to this, can’t suck myself up any more.”

I approached the massive 4 foot cock and wondered how best to handle it. It was thick, but when I bent over it and wrapped my arms round it, I found it was possible. Expando gave a quivering moan as my embrace made the cum still trapped in his suit slosh round, not to mention the way my hands rubbed the underside as I tried to find a good grip probably stimulated things as well. With Density’s help to keep his balance and me gripping his cock to keep it from swinging uncontrollably we started the process of turning him around to face the hallway.

Despite myself I couldn’t help but bone up at handling such a massive dick. I’d thought mine was huge not that long ago and now I was comfortably hugging a penis. I think Expando could feel my hardon poking his, the way he was moaning and grunting as our motions made me almost grind against it. It felt really good, so much so I think I stated leaking pre, but I couldn’t take the time to check. Density was determined to keep up momentum.

“Nearly there,” he grunted as he helped Expando lift a leg and take one tiny step forward.

“You’re doing great guys,” Expando giggled, although it turned into a wavering moan as I tried to shift his balls for another step. “You especially Super Dick. It’s so cute the way you just disappear under my pecs like that.”

I looked up from my position, crouched down with the hero’s nuts filling my arms and his cock slung over my shoulder, throbbing warmly against my cheek. His pec shelf completely blocked his face, and when I leant back, I could just see his smirking face looking down at me.

“There you are,” he all but purred and I felt his dick twitching beside me.

“Lift, Steve,” Density barked.

“Sorry,” I mumbled, ignoring the tingling sensation in my nuts as I got back on Expando’s.

After a few more grunts and tugs we’d managed to get Expando to the mouth of the hallway. We took a moment to try and form a plan, but I was beginning to think it was doomed to fail from the start. I was in front, standing the the hallway, Expando’s cock stuck out before me, using it to hide my own erection. I could see Density looking over Expando’s trap, frowning at the close proximity of his mighty chest and the hallway walls. I could hardly see his arms. Meanwhile Expando himself was still grinning from ear to ear, ever so slightly rocking his hips so his dick would rub pleasantly against mine. I found my hand going to rest on his head, rubbing at the underside to tease the glands, making his grin wider and his eyes roll in bliss.

“Let’s give it a go,” said Density, getting into position behind Expando’s back and ready to push. “We’re going to have to go in at an angle, and maybe you will have to break the walls a bit.”

“Fine by me,” smirked Expando. He winked at me. “Tug away, Super Dick.”

I wrapped my arms around his cock again and helped keep it under control as Density pushed and Expando lurched. He stuck his left arm forward, getting it trapped between the wall and his pecs. The plaster crackled and bowed against his bulk. I heard Density grunt as he pushed again, heard the walls creak as Expando’s bulk filled the space.

“Fuck,” Density grunted.

I lost my footing and fell against Expando’s dick, making him cry out in pleasure.

“What is it?” Density asked.

“Nothing,” said Expando quickly, looking down at me and winking. “Just keep pushing and I’ll try and get through.”

Expando rocked his hips, making his dick poke against my groin. I could feel my cock rub against his spongy mushroom head and had to suppress a moan myself. My dick throbbed all the harder, pushing back at the much larger one and begged to rub back. Biting my lip, I gripped Expabdo’s cock head and ground my shaft against his. He nodded, eyes closing as he too tried to keep quiet, grunting as he began to buck his hips more vigorously.

I got knocked into the wall by his thrusts, struggling to cling onto his dick, my grasping only rubbing it more vigorously for him. The fat head of his dick kept pressing against my whole shaft, almost kissing it. It felt soooooooo fucking good, my junk tingling all over with pleasure. With a start I realised that tingling sensation was familiar and looked down.

My dick was growing again. It was shiny and slick with pre as my hips rolled to continue humping myself against the massive Lycra covered cock. A small part of me knew this should be cause of concern…but the sensation just felt so good. I could feel my balls rubbing more and more against my thighs as they too joined in on the growth. It was as though I could feel them filling up with cum, producing more and more of it based on my aroused state. I gripped Expando’s cock head harder, rubbing at it more vigorously, causing Expando to groan out even more.

“What the fuck are you doing?” I could vaguely hear Density complain. “You’re hardly helping at all, Expando, stop bucking your hips and suck in your chest or something.”

“W-w-will do,” Expando stammered. “I’m ssssooo close. So close. Keep doing what you’re doing, Super Dick.”

I could feel my balls swelling up rapidly, slapping against my thighs and Epando’s cock head. My own cock head was now travelling up my torso, slapping against my chest with my motions. It kept swaying close to my face and I found my mouth opening, tongue searching to make contact. It started smacking against my lips and I felt my knees start to shake.

“Oh yes, come on, come on, almost there” chanted Expando. “See if you can aim it this way!” he laughed, opening his mouth wide.

“Aim what? What are you talking ab—Steve, no!!”

I had just lapped at the pre oozing from my slit when a hand grabbed me by my collar and yanked me backwards. I lost my grip on Expando’s cock just as I heard him grunting and crying out.

“Fffffuck!!” he roared.

I didn’t see what was happening but from the noises of bliss I guessed he was cumming. Meanwhile I was splayed out on the floor of the main corridor, my dick throbbing in fury at being denied release again. My balls went painfully tight as they bloated up with unspent cum. I was ready to take my meat in hand and beat it myself to relieve the pressure, when I noticed the figure standing over me.

First I noticed the sturdy, sculpted legs stretching up either side of my head. They were covered in red Lycra, so tight I could see every head of muscle on his thick quads. Then there was the generous bulge at his crotch. Beyond that I could see abs and chest, bare of any super suit covering apart from what looked like a leather harness strapped over his full chest. The skin was a dazzling bronze, almost appearing to glow with its own inner light, with blond hair peppering the abs while coating the chest more vigorously. Looking beyond that chest I could see a chiseled jaw beneath a metallic golden mask which looked like the sun, the wavy sunbeams creating a crown like affect. There was the cascade of luxurious blond hair, it was more like gold and glowed even more so than his skin, and finally a set of crimson wings creating a halo of sorts.

“Who are you?” he demanded, his voice deeper than Density’s and not a glimmer of humour that sparkled Expando’s words. “How did you get in here?”

I couldn’t find my voice as I scrambled to my feet, fumbling with my balls and cock. I tucked my chest high hardon up my shirt in an attempt to keep it out of the way, though I doubted it did anything to improve my appearance. I still had nothing below the waist apart from socks and my nuts were still swinging free around my thighs. “I Erm…I am…erm…my name is Steve,” I said somewhat lamely.

The hero I now recognised as Icarus folded his arms over his powerful chest. He tilted his head to look round me, drawn by the gasping sounds of fading pleasure as Expando revelled in his afterglow. After giving me one more piercing look, Icarus pressed something on his harness and his wings folded in, somehow disappearing behind him. He then moved around me to peer through the doorway. Curiosity got the better of me and I followed to have a look.

Expando was still wedged in the hallway, pecs heaving as he gasped for air after his intense orgasm. Cum had leaked out of his low neckline, the suit around his dick looking bloated with the rest of the cum that was still trapped inside. The material had darkened even more from the abundance of spunk, but still managed to keep it inside. Just over Expando’s swollen trap I could see Density frozen like a deer in the headlights of Icarus’ gaze. Expando recovered first.

“Morning, Icarus,” he panted, still trying to catch his breath. “Could you tell me if there a cute guy with a massive dick under my even bigger dick? He was there a second ago, I can’t feel him and as you can see my vision is somewhat compromised of anything too close.”

Without looking, Icarus grabbed me by the collar and hauled me into view. Expando’s eyes brightened and his grin grew. “There you are, Super Dick. No use trying to hide your cock under your shirt, glad to see you haven’t blown yet. Why don’t you undo a few buttons, come here and shove it in my mouth. I’ll help you out again and you can watch me grow even bigger!”

“Shut up, Expando!” growled Density.

“You did this to him?” Icarus asked me. His voice was oddly cold considering his body seemed to be radiating heat now I was so close to his bare skin. “Your erm…semen caused him to grow?”

“It was the Body Builder, Icarus,” Density cut in. “I think he had some kind of reaction from the formula and now—”

“Come out here Density,” Icarus grunted irritably. “Phase through the walls so I can see you properly.”

“Sorry, am I blocking the way?” Expando giggled. “But come on, I’m a way better vi—ow!”

Density smirked as he disappeared further into the room and then after a few seconds stepped out through the wall and into the corridor. His eyebrows lifted when he saw me with my dick stuffed up my shirt but quickly gave Icarus his full attention.

“Well, at least you’re still in proportion,” Icarus said, giving his colleague the once over with a critical eye. “Anything extra in there or are you just enjoying yourself?”

Density’s cheeks coloured as he put his hands over his crotch, hiding the boner he’d hadn’t quite tucked away properly. “Sorry, Expando was making such a racket and—”

“Oh shut up!” Expando yelled from out of sight. “Just because you kicked my butt doesn’t mean I forgot how much you were fondling it.”

“Enough,” Icarus sighed with a resigned groan. “Why is Expando like that?”

“I blame his parents,” mumbled Density.

“Fuck you!”

“I said enough! Answers, Density. Now. Who is this guy and why is he on site? I’m ignoring the enormous genitalia for now but I will come back to it.”

Once Icarus had been filled in on the situation, I got the full brunt of his stare. My cock twitched guiltily against the confines of my shirt, still rock hard, refusing to go down and oozing pre constantly. Despite the situation, seeing Density in his skintight uniform and Icarus with his bare torso rippling with every motion, I couldn’t help but admire their musculature which kept me hard. I’d always had a thing for muscles, but it had never been this bad where I couldn’t calm myself down. Then again, my dick hadn’t been able to reach my chest before today either.

“This is all a bit beyond me,” said the shirtless hero, stroking his strong jaw in thought. “So it’s clear this guy’s semen caused Expando to bulk up. The fact he was shot with one of the Body Builder’s darts is clearly at the root of this, however I don’t understand how that’s caused his testicles to replicate the bulking formula.”

“Well, Steve, you’re a scientist,” stated Density. “The Body Builder was after your partner, so you must have been working on something he was interested in. Could that have caused you to react in this way?”

I shook my head. “We were working on cancer treatment, hardly something a super villain would be interested.”

“What kind of treatment?”

“It was based around the idea of promoting healthy cell growth to increase recovery.”

“Growth?” Density echoed.

I shattered his ‘eureka’ moment with a shake of my head. “Just because I said ‘growth’ doesn’t mean this is what we were aiming for.” I gestured at my dick still throbbing under my shirt. Part of me was fantasising what it would be like for Density and Icarus to come up either side and grind their great pecs against it. “It was strictly at the cellular level, nothing to effect testosterone production or increase of actual muscle mass.”

“Well, we’ll put the ‘why’ to one side for now,” said Icarus, “perhaps we should look into how to reverse the effects. The Body Builder’s formula has never lasted very long before and yet by the sounds of it Expando’s been like this for a while. Did you say your penis shrank back down after you ejaculated?”

I nodded, remembering how Expando’s lips had felt around my sensitive head. How my dick had shuddered with every shot of cum and shrank down, having emptied my nuts and filled Expando instead. “Yeah, it didn’t go back to normal, for me I mean, but at least it was manageable.”

“Then perhaps we should kill two birds with one stone. Collect a sample of your semen for tests and in doing so reduce your genitalia so they aren’t so… distracting.”

“I can help with that.” Density sounded very eager, shuffling forward in a way that reminded me of an excitable puppy.

“No,” Icarus said sharply. “We can’t risk anyone else ending up like Expando.”

“I’m fine!” the muscle blimp called. “I think I’m getting used to the mass now, I can move a bit better.”

The three of us came back up the doorway, looking in on Expando. He was still wedged in the corridor, cum leaking out around the low neckline of his suit. There was also a few sticky ropes of it on his fingers, as though he’d managed to fish some from his cleavage but had failed to bend his arm enough to get it to his mouth. “See, look,” he said, swinging his hips causing his colossal dick to smack against the walls with wet, meaty thwaks.

“Wait,” Density said, as Icarus made to turn away and ignore the phallic display. “Look at his chest, it’s not as tightly packed against the walls.”

I’d been so wrapped up in the idea of Expando trying to feed himself bigger off his of cum I hadn’t realised that Density had a point. While the rubberised hero was still plenty big and bulgy as ever, he wasn’t filling the corridor as much as he had before. Expando’s cocky expression cracked as he too started to realise he wasn’t as massive as before. “Ah shit.”

“I bet his cumming helped loose some size,” said Density. “Just like it did for Steve and his cock! Maybe if we get him to blow enough times he’ll shrink back down.”

“Do I have to?” Expando all but whined.

“Yes,” says Icarus bluntly. “You can help him out Density, I’ll take…”

“Steve,” I supplied.

“Steve somewhere he can relieve himself in private. It will reduce the risk of his radioactive semen making anyone else blow up.”

“What about Expando’s c… semen?” asked Density.

“Well considering he’s been stewing in it in his suit I think it’ll be fine. Just don’t let him eat it, just in case.”

“Are you sure you can’t sort Expando and I’ll help Steve…” Density’s question withered at the look on Icarus’ face.

“Let’s take you somewhere quiet,” Icarus said, gesturing for me to walk on.

With as much dignity as I could muster, I waddled forward, being mindful of my nuts bumping against my thighs and my cock rubbing against my shirt in a heady mix of discomfort and pleasure. I weighed up the idea of letting it out but thought at least in the shirt it was more out of the way than letting it swing.

“I’m waiting,” I heard Expando say in a sing song voice behind us. “I know you’ve been wanting to ride his dick all morning, why not give mine a go.” I couldn’t hear Density’s reply, but whatever it was it made Expando giggle. “Yeah yeah, put those arms to good use and pump this beast for me.”

The moans of pleasure slowly faded, but not before they put images in my mind of Density wrestling with Expando’s massive dick. How would it feel to have those sculpted arms encircling his shaft, squeezing it and surrounding it with muscle. I really wished I had Density to help with my dick, as nice as it was to see Icarus’s full chest on display bulging against his straps, I doubted he’d be willing to be as hands on as Density would have. I remembered his kiss fondly, sending a jolt of pleasure through my groin and making my balls feel full and heavy.

“Shit,” I moaned, I could see my shirt darken as my cock head flared and a copious amount of pre oozed out. I couldn’t tell if it was my imagination but it was hard to tell if my duck was just throbbing or if it was growing as well.

“Be careful,” said Icarus, eying the floor for any drops of pre I might have left. He looked around and took me by the arm, making me walk faster towards the lift. As we waited, I couldn’t help but eye his nipple which was tantalisingly close. My mouth watered and I had to swallow, tongue longing to roll over it, in spite of the chest hair I’d undoubtably end up having to pick from my teeth. The lift doors opened and he dragged me in.

While he pressed the buttons for a lower level, I caught the first glimpse I’d had of myself after my change.

I looked short next to Icarus, my legs twig like and arse pancake flat compared to his tights clad excellence. But then there was my cock and balls. Both my balls were about the size of a football resting a top my thighs, and the dick up my shirt was so obscene. The tails of my shit just brushed the top of my sack while the shaft pushed at the buttons further up. The cock head looked like it was struggling to break free of my collar, and having it so close to my face was proving to be almost too tempting. I remembered in my youth trying to suck myself off to no success, but now it would be just a case of leaning forward and guiding my cock into my waiting mouth. The slit stared back at me as I looked down at it, licking my lips.

“Hurry up,” Icarus grumbled, jabbing the buttons. Coincidentally they did open and he ushered me out into another corridor, this one a lot darker and colder, causing me to shiver as the air ran up my sack. He grabbed the first door and pulled me into a vacant room.

It had the same layout as Density’s upstairs, if a little smaller and this one completely devoid of furniture. It was even colder in here and Icarus’ footsteps echoed loudly off the bare walls. “There’s a bathroom in there,” he said curtly, “do your business and aim for the tub.”

And with that he shoved me into a tiny bathroom, closing the door promptly behind me. I rubbed at my arms, looking over at the untouched and somewhat dusty surfaces. It was clear these rooms had never been used. My cock gave a painful throb and I decided to stop worrying and have a much needed wank.

I unbuttoned my shirt and chucked it into the basin. I then removed my socks despite the cold because I felt like a twat walking around in noting but them. Once completely naked, I touched my dick.

It was so sensitive. I shuddered from the intense pleasure just stroking the tight skin brought me. It was as though I was being punished for ignoring it for so long. I needed both hands to circle the beast, squeezing it between them and feeling it pulse and throb against my grasp. Despite how pent up I felt, I still took it slow, loving how it felt and wanting to stretch it out just a little bit. My cock was so eager however, it didn’t take long for my head to flair and a copious amount of pre oozed out and dribbled over my fingers.

Remembering I was supposed to be cumming into the bath I turned round and started to push my shaft downwards. I hesitated however, my one eyed trouser snake staring back at me, the idea of giving myself head drifting back to the forefront of my mind. My pre slick fingers glided over the head and I felt my balls lurch and swell with building arousal. My other hand absently reached down to stroke the swollen orbs, looking down at the rest of my skinny body. I began to wonder what I would look like with some extra muscle to go with this massive cock…

I mean, it couldn’t hurt right? Just a mouthful would do. It’s not as though I couldn’t leave a hefty sample with these massive nuts, they’d hardly miss a mouthful.

Before I could change my mind, I wrapped my mouth around my cock head. It was pretty wide, the head alone easily filled my mouth. I gripped the middle of my shaft, holding it close as I tried to take more, but it was a bit thick for my unpracticed throat. I blamed it on not having sucked a cock as big as mine before, which made my balls bulge out that little bit bigger. My dick was bigger than any guy I’d been with, I was so big I could suck myself off and my pre tasted sooooo good. I couldn’t get enough as it filled my pallet and slipped warmly down my throat. I began to stroke my shaft more vigorously, hungry for the real thing, to maybe get big enough muscles to fuck my own pecs! Fuck I wanted to fuck Density’s chest so bad.

A low moan left my throat as my balls clenched. I gripped my shaft tighter and pumped it for all it was worth. I swear I felt that first shot travel up my dick, as hot and fierce as lava erupting from a volcano. The head flared in my mouth and my cheeks bulged with the massive load. I wrapped my lips tightly around it, sucked and swallowed, only managing to get a portion of it down. The next shot came before I could finish the first, filling my mouth again. I gulped, but the next one was already surging. I hadn’t expected there to be so much and for my cum to be so thick! As I swallowed and swallowed, my mouth almost overflowing with cum, I realised I was only supposed to have had one mouthful. I lent over the bath, releasing my cock with a wet plop and then tried to push it down to aim for the tub. It was so hard, both hard to aim my dick and my dick itself so solid it was a struggle to go down. Volleys of spunk spattered on the tiles, coated the taps and pooled on the edge before I managed to get the monster under control.

“Oh shit,” I panted, cum dribbling on my chin as I saw a bit of a roundness to my belly. It wasn’t as prominent as Expando’s had been, just like I had a food baby after a heavy meal. That was more than one mouthful. My last few shots were somewhat marred by a sliver of dread at the thought of how big I was going to get. It wasn’t the growth I was worried about, so much as Icarus would probably be pissed off.

I massaged the last drops of cum from my massive dick, waiting for it and my balls to go down. I was rubbing my hand over my cum slick head, brining my sticky hand to my face to lick them clean. In for a penny, in for a pound, and not as though it would make that much of a difference.

The cum in my belly churned when my cock didn’t start shrinking. When Expando had sucked me off, it had practically shrunk with every shot until it was more normal sized. Now it was still as big as ever. What if it didn’t go down? What if I was stuck like this now? What if—

“Fuck!” I gasped in shock as the most incredible heat washed through my nuts. I groped them, feeling the firm flesh start to push back, expanding bigger and bigger. They swelled between my legs, upsetting my balance as they went from footballs to basketballs and still growing bigger. I grabbed at them, holding them close as though hoping I could somehow stop the growth by pushing them back in, but the cum bags just bulged against my hold, spilling over my hands as they reached beachball size and still kept growing .

“Everything all right in there?” Icarus asked from the other side of the door.

“My balls are growing!” I cried back, turning round to head for the door. My growing nuts sloshed and swayed, unbalancing me. I fell into the side of the bathtub, sitting on the edge as my balls gave a violent lurch and swelled even bigger. My legs splayed out and they dropped past my knees, reaching against my calves as I was forced to man spread. I could do little as I perched on the edge of the tub, watching my nuts swell and drop towards the ground.

A tingling sensation in my dick brought my attention up in time to see it too was joining in on the growth. The shaft throbbed thicker and longer, pointing towards the door. My mouth dropped as it grew across the length of the little bathroom, my head kissing the door while I was sat on the opposite side of the room. I placed a trembling hand on it, head spinning at how little my handspan could cover it, my palm resting comfortably on the top. No way could I grab it, not even with both hands. I could probably only just get my arms round it at the point.

The bathroom was starting to feel a bit cramped as my balls now touched the floor, swelling hotly against my legs and feet while my cock pushed at the door, sliding upwards as it kept getting longer, getting thick enough to rub both the basin and the toilet. I felt the vibrations of the wood as Icarus knocked.

“What was that?” he called from the other side. “What’s wrong with your balls?”

“They… they’ve grown again. My dick too!”

“What? I’m coming in.”

“No, wait!” I called, almost falling in the tub when Icarus pushed at the door. It was a testament to just how hard my dick was that it halted Icarus from opening the door fully. My head slid up the door, but the middle of my shaft pushed against the underside of the basin, keeping it from going anywhere higher and blocking the door way. “Ouch!”

“What’s that?!” Icarus yelled.

“My dick!”

Icarus pushed harder against the door, enough to stick his head in. I saw his eyes widen when they took in the massive, throbbing shaft jutting from my groin. It had to be about 5 feet long to cover the bathroom, bigger than Expando’s had been.

“Super Dick indeed,” Icarus breathed.

Gently, he squeezed an arm in, reaching around to try and push my dick further along to get in. His hand was deliciously warm, unnaturally so. It felt really good on my super-sized and super sensitive cock. The head moved to the edge of the door, getting squeezed between it and the wall. I let out a mingled cry of pain and pleasure, causing Icarus to curse and scramble.

“Sorry,” he grunted, squeezing in through the narrow gap. He managed to get in, almost falling over the toilet as my cock throbbed and pushed the door closed. “Fucking hell,” he breathed, looking along the length of my shaft to me perched on the bathtub. His eyes widened even more when he saw my balls resting on the ground. “How did this happen?”

“I erm… well I may have… accidentally got some cum on me,” I hedged. “It was hard to—I mean difficult to aim my cock.”

“And it only made your genitalia grow,” Icarus stated, taking in the lack of musculature on my skinny frame. His eyes appeared to linger on my bloated belly. He moved a bit closer, heat radiating off of his body in the tiny room as he peered into the tub. “I’m going to assume there was more in there. You forgot to put the plug in.” he said, wafting a hand in front of his face.

Blinking I twisted myself to look down at the slowly draining tub of cum, flowing steadily down the drain I had forgotten to fill in my haste to get off. Well, I was no doubt plummeting in Icarus’ eye even more now. Too stupid to remember to fucking put the fucking plug in.

“So how much did you get on you?” he asked.

“Erm… I don’t know.”

“Did you swallow any?”

“No.” I said, far too quickly to be believable.

“Uh-huh. Well, it’s just I find it odd that you grew this much from just getting your semen on you, when I have seen your python leaking constantly ever since we met. If it can run down the shaft of your penis and have no effect, why had it not caused more growth before now? And yet, a few misfires has caused this?” he patted my dick, his fingers intentionally or not drumming a beat on my meat that made my toes curl. My dick throbbed in excitement, part of it brushing against Icarus’ warm hip. “You drank some, didn’t you.”

It wasn’t a question. I couldn’t look at the glower of disapproval from behind the sun crown and instead lowered my gaze, taking in the sculpted bronze body standing next to my staggering dick. “Yes,” I mumbled.

Icarus pecs rose as he took a deep breath and sighed. “Hoping for a bit of muscle I assume?”

I nodded.

“Well, at least we know it has to be ingested to have any affect, so I don’t have to worry about where I step. That, and if we get you off now and you don’t eat it, we should be able to get you small enough to get you down to the lab.”

“We?” I repeated.

“Just to make sure you don’t feel tempted to have another sample. And,” Icarus jabbed a thumb over his shoulder at the door, “I rather have an easier time with the door.”

And with no further warning, Icarus hugged my dick. His thick, solid arms encircled my shaft, pressing his slabs of pecs against it too, surrounding my shaft in the warmest hug I’d ever had. My balls shuddered and swelled with arousal, my dick fattening up within his grasp as he slowly started stroking it with his upper body.

“Oh fuck,” I breathed, bracing myself against the tub as he worked my dick, almost pulling me from my perch. “Oh fuck! Why… why are you so hot?!” I sputtered.

For the first time, Icarus gave me a genuine smile. “Diet and regular exercise. Sorry, I don’t joke often but you’d be surprised at how often I get that question.” He tensed his chest and flexed his arms as he continued to stroke my massive shaft. “I’m essentially solar powered; hence why I go out with little on as is socially acceptable. I store the suns energy in myself to improve my strength, and it is stored as heat. I can also use that energy to run a bit hotter… like so.”

Icarus released the middle of my shaft, leaning over the toilet to put a hand on the underside of my cock head. He began rubbing it, his palm heating up and gliding teasingly over the tight, sensitive skin. My head was spinning, it felt so good, and I couldn’t believe Icarus was so enthusiastic about it all. Despite his warm skin I’d found his attitude towards me cold and distant. He’d told me to sort myself out before and left me too it, now he was more hands on.

“Fuck this dick is incredible,” I heard the hot hero mutter, pressing more of his body against it as he tried to get closer to the head. I could feel his crotch rubbing against my shaft. “Can’t believe how big it is, how great it looks, how it smells. Makes me wonder how it tastes, your cum? Was it good?”

I could only nod and make noises of agreement. I could feel his rough chest hair and the straps of his harness rub against me, a heady contrast to his soft, warm hands gliding over the head. He was trying to get to the head, practically going under my dick and trying to push me back so he could get between it and the door. I was hating how small this fucking bathroom was, pressing myself against the wall, balancing over the tub as much as I could while my nuts still rested heavily against the floor. I was trying to think of another position when Icarus managed to lap his tongue against my glands.

“Fuck!” I moaned, slipping and falling into the tub, legs going in the air, my nuts slamming against the side and getting pulled painfully. Icarus quickly took advantage as my cock slid back, to jump up, wrap his lips around as much of the head as he could and start lapping hungrily at the pre flowing. The strain on my nuts was too much for me, so I lifted myself back out of the tub, my cock almost smothering Icarus’ face. He in turn was pushed back against door, getting wedged in the corner of the room, my dick stuck over his mouth. His hot hands pawed at my shaft to try and push it off but it was only turning me on more. I felt my balls tremble, swell up tighter with cum just before I was pushed over the edge.

Fuuuuuck!” I roared as my massive nuts started to empty. Hot cum fired from my dick, flooding into Icarus’ mouth, perfectly positioned at the slit, who had no choice but to gulp it down. It was too much for him to take, cum leaking out of the sides of his mouth, dribbling down his chin onto his chest. He was soon slick with it, making his grasping attempts to push me off futile as he just kept sliding off. A small part knew I should have moved back, let him free, but his mouth felt soooo good. It wasn’t until my dick began to shrink down that Icarus managed to push himself free.

Tiny sticky threads of my cum still conducted his lips as he opened his mouth in a hungry gasp for air, eyes wide while he half-heartedly pushed my still jerking cock out of the way, even as the ensuing volleys rained down on him. My cock twitched and throbbed in the fading throws of my orgasm, each shot causing it to shrink as well. My nuts began to rise from the floor as they too began to empty. When I had finally stopped cumming, I’d only lost about half of my size, my 2 and a half foot cock drooping forward, almost touching the large puddles of cum on the floor.

The only sounds were mine and Icarus’ heavy breathing with a few wet splats as my cum fell from the walls and ceiling. And Icarus I guess. The front of his tights were darkened with cum, making them cling to a hefty looking dick. I actually blinked at the thickness of the monster the hot hero was smuggling, until my eyes travelled slightly higher.

Despite the difficult he’d had with taking my cock, Icarus’ abs were distended with the amount of cum he’d swallowed. His previous flat, tight core had swelled into a bit of a gut, the muscles somehow still there giving it the appearance of an armoured tortoise shell. Icarus brushed his cum slick hair back, looking down at his cum filled belly in shock before his terrified eyes found mine.

“What did you do to me?”

Almost falling in his haste, Icarus wrenched the door open and fled back into the room. His footsteps squelched as he left cum covered footprints on the floorboards. Not sure what else to do, I followed after him, after taking a futile second to cast my eyes over the bathroom for something to cover myself with. Even if there had been towels to hand, they would have been drenched in cum. I couldn’t even see my clothes, no doubt buried under the cum.

I found Icarus by the window, staring at his distended belly bathing in the sunlight. When he heard me approach, his head whipped round and his hand lashed out with an accusatory finger. “You stay there!” he snapped, scowling when he noticed cum was dripping from his pointing finger.

I froze, my dick swinging between my legs. It was still 2 and a half feet long, my nuts having shrunk to a pair of manageable grapefruits resting warmly against my thighs.

Satisfied I wasn’t going to come any closer, Icarus returned his attention to his distended belly. It gave me a funny feeling, seeing that I’d filled this chiselled hero with so much cum I’d bloated him up. Until today it had never been something I’d ever thought about, now I’d done it twice. Expando’s belly hand been bigger, had looked squishier than Icarus’s almost roid gut of bulging abs. If Icarus hadn’t pushed my dick away, if he had drunk everything my massive nuts produced…how big would his belly have been? Then of course, there was the growth still yet to come.

“What’s going on? What happened?”

Density and Expando jogged into the room. Well… Density jogged, Expando had a sort of staggered gait. He was back to his normal size, the smell of cum rapidly filling the room. He gingerly adjusted himself, presumably after all that wanking his cock was undoubtably a bit sensitive. His eyes first went to my dick, tongue darting out for a fraction of a second before lifting his gaze to my face to give me his trademark smirk. Then he caught sight of Icarus and did a double take.

“No way!” he laughed incredulously. “You were giving Density and me all that shit and as soon as you get Super Dick alone you guzzle his cum yourself?! Hypocrite.”

“Shut up!” Icarus barked, jabbing a finger at me. “He did this to me!”

“What?!” I sputtered. “I don’t recall forcing my dick into your mouth! You seemed quite eager to do that yourself!”

Icarus made to take a step towards me and then at the last second changed his mind and instead stepped back. “He drank his own semen, made his penis almost fill the bathroom so that I had to come in to help. He then nudged the door closed with his dick, essentially trapping me in there.”

“And what, your mouth was open shouting ‘no, stop cumming’ and you accidentally swallowed some?” Expando quipped. His arm stretched across the room, his powers clearly back, to poke at Icarus’s cum gut. “You must have had your mouth opened a long time.”

“Fuck off!” Icarus smacked at Expando’s hand until the rubber hero retracted it. “When I was in there with him, my head got all… cloudy. I… I started… I started touching his cock and…and—”

Icarus let out a low moan, clutching his belly. I could almost hear it rumble, see his skin tremble as my cum began to take effect. Slowly his stomach began to recede, retreating back until his core was flat once more. As it contracted, his chest was already expanding, plumping up and pushing against his harness. His pecs swelled bigger and thicker, bulging against the harness to make the leather creak. His arms began to ripple and bulge, forearms twitching as he clenched and relaxed his hands.

“Ooooh…” Icarus stammered, chest rising and falling with his increasing breaths, going up with each breathe but never going down as much with the exhale. “Oh fuck…ahhhh oh shit.”

The front of his tights were rapidly filling, his crotch ballooning out faster than his thighs were thickening. The heads of muscle of his quads were rising out even more prominently than before, rapidly surpassing my waist in thickness. They were somewhat overshadowed, quiet literally, by his bulging crotch that swelled out, the basket sagging with the increasing weight. What was more impressive was the thickness of his shaft that was pressing clearly against the material. I could see the head of his dick, his shaft narrowing just at its base before bulging out again down towards his groin.

“Fucking hell,” Expando breathed. “That’s a fat dick you’ve got there, Icarus.”

Icarus hands quickly went down to try and cover himself. The motion made his pecs bulge out, spilling out even more against his constricting harness. His hands groped his inflating crotch bulge, pawing at the thick meat straining against his tights, failing to cover it as it just swelled thicker and thicker. His spreading lats pushed against his thickening arms, biceps blowing up and triceps expanding, all that muscle starting to battle against each other for space. His fumbling fingers were being pried apart, by his swelling junk and his muscles forcing him to move his arms out.

Unlike Expando’s super suit, it was clear Icarus’s wasn’t as stretchy as his rubber colleague. The seams of his tights began to spilt open, showing off the solid bronze flesh of his ripped quads. His heavy basket was drawing the waistline down, showing off the base of his shaft as it threatened to swell out. His movements were becoming more frantic as he huffed and moaned, trying to keep his tights together even as more splits and tears began opening all over. Calves rose like melons from the back of his legs, his quads surpassing his own waist in thickness and the middle of his fat dick spilling out while the head curved in, still covered. That is until the waist snapped and out it sprang.

“Whoa—!” said Density, Expando and I.

Icarus’s dick was a monster. It swelled out from the base of his groin, thickest at the middle before tapering down to the head again, it was so thick it’s weight forced it down, almost touching the floor already, his balls trapped beneath it pinned to his thighs that were pressed so tightly together he was in danger of pinching his sack if he wasn’t careful.

“Getting… too big,” Icarus wheezed, his harness cutting into his meaty chest. With a grunt one of the straps snapped, the separated ends cracking like whips as they were flung back by his swelling chest. What remained still dug into his shoulders, the sheer width of his arms would make it impossible to pull them off that way, trapped at the narrowest part of his underarm with no hope of movement. “Make it stop!”

Purely by coincidence his growth did taper to a stop, leaving Icarus flailing as a pumped up muscle blimp, with his torn harness and tattered tights. He wasn’t as big as Expando had been, he was able to waddle on his own power, spinning in a circle as he tried to look at the muscle expanse his body had become. His dick bobbing and swaying in the wake of his movements, the head just a few inches shy of the floor.

“That’s hot,” Expando purred, rubbing his crotch. “Fuck, I miss being that big.”

“Would you shut the fuck up!” Icarus bellowed, advancing on Expando like a moving wall of muscle, his dick leading the charge. It flopped and swayed, getting jostled by those shifting quads and the waddle of his gait. Expando just giggled, opening his arms and catching the monster cock as it pushed into him. “Get off!” Icarus growled, struggling and failing to reach Expando. His dick was just that bit longer than his arms, adding that to the fact his pecs limited the reach of his arms too meant that Icarus couldn’t get his hands on his stretchy tormentor. Expando had no difficulty get his hands all over Icarus’s dick though.

“Hey, I’m just helping you out,” Expando giggled, easily avoiding Icarus’s clumsy swipes at him. “You want to get back to normal don’t you? Gonna have to milk this python.”

“I can—nrgh—do it—rah—myself!” Icarus grumbled, grunting with every failed reach.

“You can’t even reach me mate, how you gonna pump this beast if you can’t even do that?” Expando lazily dodged Icarus’s next swipe then leant in and kissed the flaring cock head that filledhis hands.

Icarus’s movements faltered, “Fffuuuck” he moaned, muscles twitching and his cock throbbing.

“I know what I’m doing mate,” Expando cooed soothingly, moving his hand in teasing circles over Icarus’s sensitive head. “You two just gonna stand there with boners or you gonna help?”

Density sheepishly came forward, his purple speedos tenting with his erection. He tentatively watched Icarus for any objection before placing his hand on the thick shaft. “It’s such a thick beast,” he breathed, his hand barely able to cover a fraction of its girth. It was almost as thick as my cock had been at 5 feet, and this was only about 3. I can’t believe I was saying a dick was ‘only’ 3 feet, my sense of dick size had forever been altered now.

I felt a pang of jealousy as Expando and Density began rubbing and kissing Icarus’s bare beast, his pecs jumping as he panted and gasped in pleasure. The way his fingers were twitching and how his arms kept bending, it looked like he was trying to join in, to feel his own dick, but his massive bulk kept getting in the way. No, it wasn’t his dick he was trying to reach.

Silently, I approached the trio. They were all so wrapped up they didn’t pay me any mind. Expando and Density were kissing each other with Icarus’s huge cock head between them, Density rubbing against it with his chest while Expando’s arms were stretched to stroke the shaft and fondle those colossal nuts. Icarus’s massive arms were still flexing and bulging as he tried to reach for his nipples, which due to the sheer mass of his pecs were pointing almost straight down. His muscles kept him from performing the simple movement, so I thought I’d help him out.

As soon as I touched his pert nipple he let out a gasp of surprise and pleasure. Over his pec shelf I could see him watching me, his mouth twisting into a scowl, the words to tell me to go forming on his lips before the pleasure of my fondling chased them away. I leant in and took the nipple in my mouth, nuzzling his huge chest as I sucked and lightly nipped at it.

“Oooooh…ffffffuck,” Icarus stammered.

His biceps bulged against my shoulder, an indication I took that he wanted me to continue. I happily obliged, groping his heavy chest in my hands, squeezing and kneading at the meaty flesh. They were so dense and felt so heavy, but still squeezable until he flexed, in which they swelled and hardened. I rubbed my hip against the base of his shaft, trying to stretch over it to reach his other nipple too, squeezing and tugging on it with my fingers.

“Ugh… aaaah!”

Icarus’s body shook as his cock erupted, spraying cum over Density and Expando, the force of the first shot driving them back with a gasp and sputter. Density stayed back, wiping the cum from his face while Expando moved back in, his mouth stretching wide with his powers to catch as much as the firing cum as he could. I kept sucking and teasing Icarus’s nipples even as he began to shrink back down.

After a few seconds his cock stopped firing, twitching every now and then as the last shots of cum oozed out. Expando stayed attached to the slightly smaller dick, sucking on the last drop before releasing it with a wet pop. He straitened up, grinning with cum dripping from his chin and patting his swollen cum gut.

“Delicious!” he giggled, licking his lips. “Although I think I might have burnt my tongue, that shit was hot!”

Icarus, having shrunken down enough to regain some mobility, took a few waddling steps away from us. He pulled a few tattered remains of his tights off of himself and then looked over his body. He was still bigger than any conventional bodybuilder, and his monster of a dick was not going to be contained by underwear anytime soon, but he could at least move with less restrictions now. He admired his arms, felt his hefty chest, stroked the base of his dick which throbbed in response, the head weighted down to point at the floor resting over his beachball nuts.

“Your help was appreciated,” he said, a little breathlessly. “I think I can deal with the rest from here alone.”

“But I didn’t get—” Density started, “—I mean, we don’t mind helping.”

“Jealous, Density?” Expando teased, grabbing his gut and shaking it in the purple hero’s direction. “Don’t worry, you can watch me swell up nice and big again after this starts working.”

“Why are you so obsessed with looking like this?!” Icarus spluttered incredulously. He spread his arms, displaying his mass in a way I think was a counter argument to his cause. He was a godly specimen of muscle and strength. I think Density, Expando and my dicks all gave a little jump.

“Because it’s fucking hot, that’s why. Just all that power, all that strength filling your body up, so swollen and massive—”

“And practically immobile!”

“So what? If I really wanted to move I’d ask Super Dick to give me another blast and just grow where I want to go. Why walk when I could be everywhere!” Expando caressed his cum gut affectionately, his mischievous eyes aglow with excitement. “Gonna get so big.”

“Well,” I hedged, hating to burst his bubble even as hearing him voice his hunger for more size was making my cock throb all the more. “I erm… don’t think you’re going to grow from Icarus’s cum.”

Expando’s hand stilled on the crest of his gut. “Come again?”

“It’s just… you drank some of your cum, right?”

“I told you not too!” Icarus snapped, bearing down on the bloated blue hero. Expando did look a bit flustered at being called out but quickly recovered.

“It was only a teeeeeeeny tiny bit. Oh don’t look at me like that,” he scoffed at Density, “my suit was full of the stuff, still is, was hardly difficult to sneak some past you. Admittedly it was hard to tell if I grew at all but I thought it was just because I’d not had a lot.”

Density cleared his throat. “I guess if we’re being honest…I tried some too.”

“Of for fuck’s sake,” Icarus grumbled, going to put his face in his hand but having trouble when his biceps and pecs got in the way.

Expando however was sputtering with laughter. “Cheeky git, you should have just said and then we could have both guzzled and grown!”

“I wasn’t sure it would work,” Density said with a shrug of his shoulder. “I only had a bit too but nothing felt bigger.” He groped his crotch. “I was so hard at the thought of it though.”

“Well you can have a bigger hit straight from the tap when I start growing,” said Expando, slapping his gut like a drum. “It’s bound to happen right about…”

We waited. Expando watched his gut expectantly, waiting for it to recede and the rest of him to start growing. The seconds dragged on, turning into minutes and still nothing happened. After almost five minutes of just waiting, Expando’s eager grin was faltering.

“I think it’s just my cum that causes growth,” I said quietly. “I don’t think I can pass it on.”

“Shit,” Expando sighed, hefting his gut and making it wobble. “Are you sure?”

“While the evidence seems to speak for itself, perhaps I could take a look?”

The new voice was a deep rumble, a ring of amusement softening the words. We all looked to the doorway to find a tall figure in a skintight green super suit, a mask that covered his head concealing all but his eyes which twinkled with an otherworldly green glow. It was the last member of the Wardens. Watcher.

Under normal circumstances, Watcher was the biggest of the team. He stood at about 6’6” with an impressive body, wrapped tightly in his green suit, darker around his arms, edges of his core and his legs with a bright section over his chest and abs. Nestled between his pecs was a rhombus with an eye symbol at its centre, and as he walked into the room his cape billowed majestically behind him. His green eyes swept over us all; Density looking bashful, Expando with his distended cum gut, Icarus naked and still pumped up to impossible proportions, and me, also naked with my unimpressive body and oversized cock dangling between my legs. We must have been quite the sight.

“I hear the Body Builder has been experimenting,” said Watcher in that low voice of his. “It appears he wasn’t the only one.” He approached me, offering me his large hand. “You’re Steven, correct?”

I took the offered hand, watching as the big, black hand squeezed mine in a firm handshake. He then reached up and pressed something at the back of his head, causing his mask to… fold away, revealing a chiseled but kind looking face behind those powerful green eyes. “Since you already seem to have seen everyone’s face already it seems silly to keep mine on. I’d still rather you call me Watcher however.”

“Yeah, of course,” I said swallowing hard. He was just so tall, his eyes were… intense to say the least. I knew he had a lot of vision based powers, it certainly felt like he was taking in every molecule of my being.

“Very interesting,” he said, leaning back and then looking at the rest of his team. “I’ve not had a full briefing but from what I gather, Steve here has had a unique reaction to the Body Builder’s formula. Who wants to tell me how this—” He waved to the pumped up Icarus to the bloated Expando. “—happened?”

“Perhaps Density should fill you in,” said Icarus. “I’d very much like to… take care of things.”

“I going to need a bit more than that Icarus. What does that mean?”

“It means he wants to spank the monkey to get smaller again” said Expando, brash as ever.

Watcher didn’t react so he was clearly used to these sorts of outbursts. “I see. I take it Icarus was bigger before you kindly took on some of his burden?”

“He was hoping to get bigger again himself,” said Icarus. I noticed his cheeks were flush, probably from having his teammate tell everyone he was wanting to slip away for a wank. If he was attempting to try and drop Expando in it and make him feel guilty for getting caught out too, the blue ball gut showed no signs of remorse though.

“You should have seen me Watcher, I was immense! Bigger than sunshine easily. Although I will admit his dick might have been a liiiiiiitle bit thicker, but just look at that monster!”

“You’re unreal,” grumbled Icarus, twisting away in a futile attempt to hide his huge sausage.

“All that aside,” said Watcher with patience, “how did this happen? With no disrespect Steven, and I don’t blame you for this, why is he even here? He should have gone to Eugene labs for observation, not sauntering around our base naked and blowing my team up.”

I really wished I had something to cover up my dick. There wasn’t even any furniture in the room I could shuffle behind to even try at modesty. My discomfort paled however compared to Density who was almost dwindling under the combined scrutiny of the rest of his teammates. The colour was draining from his face as he raised his hand.

“That would have been my fault,” he said, voice low and heavy with guilt. “The Board has already wrapped my knuckles for it. I… I just thought that…” he huffed in frustration. “I don’t know what I was thinking, okay? I’d just seen his dick suddenly grow, he was on the floor looking helpless and hot with it all hanging out and… and I…”

“Ah hah!”

Icarus suddenly surged forward, his heavy footfalls echoing around the barren room and cock flopping around as it bounced off his powerful thighs. “You see, he does something to us!”

“We noticed, big guy,” said Expando, bumping Icarus’s cock with his gut.

Without looking, Icarus gave Expando a little shove, almost unbalancing him and sending him waddling and wobbling into Density. His attention was fixed solely on me with the intensity of the sun. “When I was in the bathroom alone with him I could feel myself being drawn to him. My head was all cloudy and all I could think about was what it would feel like to get his cock in my mouth, to taste it.” Despite the anger curling off his words like smoke, his dick twitched, chubbing up as though he was getting turned on at the memory of it. “He’s probably been working for the Body Builder and is using some of his mind control tech to… seduce us until we’re all immobile muscle blimps so he can take over the city!”

I wanted to laugh. I was sure Expando would make a joke at how ridiculous the whole idea sounded, but when Icarus’ accusation was met only with silence, my throat suddenly felt very dry.

“I’m not a spy,” I said, knowing it was a pathetic rebuke. Icarus snorted dismissively and the rest of the squad now had a glimmer of suspicion in their eyes. “Please, you have to believe me, I’m not a spy, and I’ve not done any of this on purpose!”

“It might be best if we detain him,” said Watcher slowly. “Just as a precaution until we know more. We’ll have to run a background check as well as a few tests on your… predicament.”

“No.”

Hope swelled my heart as Density stepped forward, coming between me and the rest of his squad. It would be an understatement to say that having his broad back before me, a barrier against the accusatory stares of these heroes, gave me great comfort. I immediately felt safer, knowing he was willing to protect me.

“I admit I made an error bringing him here, but it was my idea. He didn’t suggest it or manipulate the situation, I just…I just had a feeling that it would be safer for him here.”

“Mind control can be subtle,” said Watcher, his tone like iron. “I can see his physiology has been drastically altered, he could be producing pheromones that have influenced your decisions. It’s obvious you’re feeling very… protective towards him, and that could be a result of—”

“No, I’m protective of him because that’s what I do, what we are supposed to do!” He cast a look at me over his shoulder, his eyes still white behind his mask, the only one in the room still wearing one. “We protect those in need. He may have been changed, been given abilities he doesn’t understand, but that’s no reason to treat him with suspicion. I would have thought you of all people would understand that, Watcher.”

“Ooooh,” Expando cooed, before Icarus cuffed him and he went quiet with a pout.

Watcher didn’t pay them any attention; his intense green eyes were for Density alone. After what felt like an eternity, those broad green shoulders loosened and he seemed to relax. “Okay, he can stay. We’ll get a room set up for you, and then I’d like to take some semen samples from all of you. Now Steve, I ask that you refrain from blowing up my guys any more so keep your samples in containers.”

“I’d make a good container,” Expando pipped up, caressing his cum gut.


So I didn’t have to walk around their base naked, they gave me some clothes. They were too big for me but at least it gave my dick plenty of room. I was grateful for the extra space, even after my dick shrank down after filling a few containers for Watcher, it didn’t seem to take long for it to start growing again. It was so easy for me to get aroused, then again I was surrounded by all these muscular studs in spandex or less.

It also didn’t help with Icarus moaning away as he gave his sample next door, then come out in nothing but a robe. It was open to show off his pecs, which while not as huge as they had been, they had a sheen of sweat to them. He nodded to one of the lab techs, his cheeks flushing when the technician’s nose crinkled. Before I could even wonder why I caught a whiff of the hot musk of his cum escaping the room. Considering when he’d went in he’d had to turn sideways to get through the doorway, struggling to keep his thick dick down as well, he must have cummed quite a lot to lose all that mass.

When Icarus had stepped aside to let the technician in, he’d looked up and seen me watching him. His lips pursed together and eyes narrowed and I felt blame shoot from that glare like a laser. He clutched his robe tighter to himself and stalked off towards the showers.

Expando had been a lot more jovial. When he’d given his sample and shucked his cum cover suit, he bounced over to me. He was back to his lithe self, having lost his cum gut and in a robe of his own.

“Don’t ask,” he said, following my gaze to his now flat tummy. “Let’s just say I’ve been asked to fill myself with a lot more water than that and help put out a fire.”

It took a minute for me to get what he was talking about until I remembered the news story from a few years back. There had been a terrible fire at an abandoned tenement building, the fire brigade was struggling to get there so the heroes had stepped in. I remembered Expando had been this huge, blue ball, about the size of a bouncy castle, getting rolled into place by Density and Icarus. His arms and legs had been lost in his bloated torso, head only just peeping out of his squishy neck and chest. He’d then spat out the water with enough force to reach the top-storey windows. After that, a little cum gut would have been easy to remove.

“Have you given your sample yet?” he’d asked. “I can help if you want.”

He sidled up closer, hand going to my crotch to feel the already noticeable bulge that had started rising while I’d been thinking how big Expando had been. Imagining if I’d turned him into that same round ball, this time filled with my cum, and how much bigger he’d have grown after that. Expando’s expression was an irresistible mix of mischief and hunger.

Watcher had swooped down on us though and shooed Expando away. “Don’t encourage him,” he’d grumbled, although I wasn’t sure which of us he’d been talking to. He stood over me for a moment, eyes on my crotch. “Have you been keeping track of its growth rate?”

I’d stammered and blushed, feeling flustered that he was using his X-ray vision to check on my junk. Looking back though, I didn’t think he’d actually needed any super vision to see what I was packing at that point. “N-not really.”

“Well, it’s just considering you just master-bated not long ago, it seems to have grown considerably in a short time.”

“Yeah, maybe a bit.” I was suddenly very aware of the hot feel of my shaft against my thigh. I might have been imagining it but I could have sworn I felt it growing down my thigh slowly but surely.

“Hopefully some rest will help. I imagine it’s been quite a day for you. I’ve prepared a room for you, I’ll take you there. Now…I don’t want it to seem like a prison, but I ask that you not leave there. I’ll come get you in the morning. I’m also not letting the rest of the team know so as to…prevent any late night visits?”

So that was how I ended up, alone, in one of the slightly better furnished accommodation rooms, trying to get some sleep. My dick was refusing to settle, steadily getting bigger and filling my head with horny thoughts. An endless barrage of all the incredible things I’d see that day, Expando and Icarus growing, kissing Density, Watcher’s arse, Icarus’s heaving pecs, Expando and his cum gut and giant dick… fuck me.

Giving up, I rolled onto my back and threw the covers off. I looked down at my spread legs, knees in the air and the impossible tent in my borrowed briefs. My cock was throbbing, straining against the material, the base visible with the waist band stretched away from my stomach and even leaving a gap at the legs as well. I could see my balls bulging out either side, smushed up in the briefs as well. It looked hot as fuck, but the uncomfortable levels were outweighing the aesthetics.

Reaching down, I lifted my butt off the bed and tried to pull the briefs down. Despite the fact I was trying to free it, my dick was making it more difficult than it needed to be. Just as I was about to fold the stretched waistband over the head, a shadow moved in the doorway.

“Need a hand?”

I gave a squeak of shock that turned into a grunt when my cock sprang free and slapped me in the chest. I tried to get to my feet, but my briefs were still part way down my legs, so I ended up rolling off the bed. The floor met my back hard enough to wind me and my cock slapped me again to squeeze out what little air I had left.

“Shit, shit, sorry it’s me, it’s me!”

Dazed and choking for breath I was then blinded as the intruder flicked the light on and bathed the room in brightness. I managed to sit up and slump against the side of the bed, the figure coming up behind me, thudding on the floor as gentle hands rubbed my back and stroked my shoulders. I took desperate gulps of air, causing me to give a few body racking coughs from my haste.

“Easy now,” he soothed, holding me like he was keeping me together. I felt comfort in his arms, despite the fact that he’d scared me into this state. Once I had some air in my lungs and oxygen was getting to my brain, I knew who had come for a visit. No longer scared, I leant back, a little surprised to feel the soft touch of a bare chest behind me rather than the slick toughness of his super-suit.

“You could have knocked,” I said, although it came out more of a croak and I had to clear my throat afterwards.

I felt Density shrug his shoulders. “I didn’t know which room you were in. I’ve been phasing through walls searching for you.”

“Why?” I asked, very aware of my cock draped over my thigh starting to throb and come back to life now my body was no longer fighting for breath.

“Is it weird that I… don’t really know? Just that I… wanted to check up on you?”

“Must be my hypnotic powers at work.”

“If Watcher catches us then I might just use that as an excuse. Joking, that would only get you in trouble and this is all me.”

Density’s hand slid down my side, resting on my hip before dipping down between my legs. His breath tickled my neck as his fingers brushed the base of my shaft which throbbed at his touch, visibly getting a little bit bigger as well. “Think he might have had something to do with it,” I said dryly.

“Maybe. I just thought…I still owed you when you first got here, before the great Expando snuck past me and—” His teeth clacked as he stopped himself. “—anyway. I know this has caused you a lot of grief and I wanted to help you with it.”

“And maybe get a bit bigger as well?”

“My motives are completely chivalrous, I promise.”

“Chivalrous? Is that your ‘sword’ I feel at my back then?”

“No, I’m just pleased to see you.”

Sighing, I sat up, shuffling away so I could turn round and face Density properly. My words faltered when I saw him though. I’d already known he wasn’t in his super-suit, but I was startled to see him in nothing but a pair of tented pyjama trousers, his tight, toned torso completely on show, and his face for once completely unmasked. His eyes were beautiful. They were a brown so dark they were almost black, but they smouldered with this inner fire. His left eyebrow had also been shaved to break off a little triangle from the main brown. It was… cute. He waited, letting me take him all in, then he lifted his hand and offered it to me.

“You may know me as Density. But you can call my Jacob.”

“Jacob.” Density had told me his name. Although I’d seen everyone else’s face and a majority of the team’s junk as well, none had revealed their names. It felt… good, that he’d wanted to open, to share his identity with me.

“Yup,” said Den… Jacob, giving me a smile. “Sorry if it’s a bit basic.”

“Yeah, because Steven is so exotic?”

“Fair point.”

I shuffled, my butt having gone to sleep from sitting on the hard floor. Den… Jacob, noticed and gave me a smile. “Why don’t we move to a more comfortable position.”

He helped me up, perching me on the edge of the bed while he stayed kneeling before me. The mattress sank as he put a hand either side of me, leaning up towards me. I brought my head to meet his and let his tongue into my mouth. Fuck he was a good kisser. Despite getting sucked off by two other heroes today, just kissing Jacob was turning me on a lot more. Which wasn’t necessarily a good thing.

Jacob pulled back, looking down and smirking. “What’s so funny?” I asked, my voice a bit breathy.

He just arched his trimmed eyebrow at me and gestures to something lower. My cock was poking his core, leaking pre on his abs and starting to bend as it tried to grow between us. My balls were rabidly filling up my lap, nearing the edge of the bed. My feet shuffled as I spread my legs a bit more to give them some more room, but I could actually see them swelling up still.

“You’re growing faster now,” whispered Jacob, his voice low. Still on his knees, he straightened his torso, taking my cock in hand. “Wow, it’s heavy. Getting so thick I doubt it could stand on its own. Think I have a way to help.” He lifted it up, the head of my dick resting comfortably on his chest. Those dark eyes blazed with wicked intentions as he gave his pecs a little flex, the muscle fibres rubbing my sensitive head. “Better?”

I couldn’t speak, the best I managed was a noise of affirmation.

“I’ll take that as a yes,” he chuckled, knocking my cock from one side to the other by bouncing his pecs. He was drinking in my pleasure, teasing me with his chest and showing off his control. Then when he leant down and kissed the head of my dick, those marvellous lips sent my head spinning. My cock lurched with a shuddering growth spurt, pushing past his lips and swelling in his mouth. He coughed and laughed, pulling back and wiping the pre that cosated his lips, unable to do anything about the rest that ran down his pecs. “Okay, guess I deserved that.”

He took a moment, looking at my cock, fingers gently caressing it. “I was hoping to try and ride this but… might be a bit big for me to handle… for now…”

“Wh… what?” I stammered.

“Think I’ve been teasing you enough,” he said, ignoring my question. “Can feel this monster getting bigger.”

Gone were the gentle caresses and butterfly light kisses. Jacob took my cock firmly in two hands, opened his mouth wide and shoved as much of my cock in his mouth as he could. He worked the shaft with his arms, bucking against it to let it run his chest, while he sucked and gagged on the massive head. I cried out, feeling my dick getting bigger in his already tight throat, forcing him to lean back and just work the head as it grew thicker and wider. There was so much pre it dribbled down his lips when he took a gasp of air, splattering on his chest and causing my dick to slide over it more freely. His tongue lapped and rolled around and around the head, furiously pumping away at my shaft. My balls gave a shudder as they suddenly swelled between my thighs.

“I’m gonna cum!” I cried, in both ecstasy and warning.

Jacob braced himself even as he continued to pump my shaft. When the first shot came it spilled out of his mouth, he hadn’t made a good enough seal. It spurted over his face and into his hair, some splattering the wall behind him. With more determination Jacob took a firmer grip on my cock just as the next shot came, his cheeks ballooning with the load. He managed to gulp and chug at least three more before he had to come up for air, earning another shot to the face before he could get his mouth over it again. I watched him work, leaning closer and closer as my cock shrank with every load, the smaller it got, the more manageable my loads became. Jacob kept sucking until my cock had nothing more to give and then sat back, looking content.

“Fucking hell,” he panted, looking almost drunk, eyes hazy and a goofy grin on his face. He whipped his chin with the back of his hand… and then flicked the excess off. “So good” he moaned. “Wish I hadn’t waited so long. Here, try some.”

“Wait—” I sputtered, but Jacob smeared his cum covered hands on my lips and then kissed me. I could taste my own cum on his tongue as it invaded my mouth, making sure I drank it down. He pulled back, still with those lustful, heavy lidded eyes, smirking and licking his lips.

“Surprised you’ve not tried some of it yourself,” Jacob said, rocking onto his feet and standing up. I was momentarily taken aback by the new swell to his belly. No one had managed to beat Expando at cum guzzling yet, but Jacob still looked noticeably bloated from my load.

“I erm… I did,” I managed to stammer once I could tear my gaze off the tent poking just beneath Jacob’s tummy. “It didn’t make me grow, just made my dick grow bigger.”

“Really?!” The excitement was hard to miss in Jacob’s cry. “Well, that’s good, means I’ll have to help you get off again to… get it back… down again. Whoa… I… I can feel it already.”

Jacob started rubbing his body, his torso slick and glistening from the coating of pre and cum. His pecs were steadily inflating, pushing out thicker, traps rising up against his neck. He grinned, flexing his arm, watching the peak of his biceps rise, fall and then rise higher again, forearms rippling as they bulked up too. He gave a grunt, whole body shuddering as his shoulders not only ballooned out but also began stretching further apart as he grew wider. He lifted his arms, letting his lats flare, thick wings of muscle that swept down to his comparatively narrow core. His abs were becoming tighter and tighter, bulging against his skin, his Adonis belt becoming chiseled as though from stone it was so well cut. The tent in his trousers was stretching out further, the legs steadily filling as the growth spread.

“Oh, fuck yeah!” he moaned, grabbing his dick and stroking it. “Fuck, it’s throbbing against my hand! Fuck it, I can’t wait.”

He gripped the waistband of the trousers, his arms bulging as he gripped it tight and then tore them apart. His cock fell out, swaying as it swung free, curving up and twitching as it grew and grew. He tried to push his trousers down but his quads were getting too thick. He had to shuffle his feet on the floor, to widen his stance as his inner thighs began rubbing together.

“Come here,” he all but growled, taking my hand and pulling me up against his body. “You need to feel this, feel how big I’m getting.”

He wrapped his thick arms around me, pressing me into his chest even as it inflated and pushed out against me. It was such a heady experience, feeling his muscles ripple, flex and grow bigger and bigger and bigger. His arms were getting heavier on my shoulders, I was almost sinking into the chasm of his pecs as they grew, his eyes drinking my reaction in and watching as he threatened to overwhelm me with his sheer size. “Fuck yes, so big,” he whispered, leaning in to kiss me, softly. Our dicks were rubbing together, although his was starting to overtake mine in size, feeling it thicken and slide against mine as it grew. It was also getting harder to kiss him the way his pecs were ballooning, soon our lips were unable to meet over the shelf he was developing.

“Ssssshit,” he breathed, while body tensing, “gotta be careful or I’ll cream myself already.”

He let me go, taking a wobbly step back and bumping into the cum spattered wall behind him. He was so blown up now his movements were becoming more difficult. His arms were fighting a loosing battle against pecs and lats, forcing them to hang out at his sides. His legs were pushing out his bowling ball size nuts while his cock throbbed towards the 3-foot mark.

“No, not yet, don’t stop yet!”

Atop all this massive muscle, Jacob’s bottom lip was out in a pout, his brow puckered as his growth ground to a halt. He hadn’t grown as big as Icarus or Expando, something I think Jacob was less than pleased about. He was looking so crestfallen it tugged at my heartstrings. He quickly rallied round though.

“Give me more!”

He took me by the hand and waddled to the foot of the bed. He then let me go and backed himself up to the edge and tried to slowly lower himself down. As soon as he bent however, unused to his new size, and perhaps the weight of his ample chest, he nearly tipped forward and would have ploughed straight into me. And probably through the wall too. Thankfully he managed to recover quickly, but he overcompensated and he ended up tipping backwards instead. It was like watching a particularly thick tree fall. The whole room shook and the bed almost crumbled under him as he landed spread eagled.

“Fuck,” Jacob grunted. He was too pumped and too heavy to get in a good position to roll over, and despite his chiseled core he lacked the strength or mobility to even sit up. It was like a tortoise trapped on its back. He tried for a while, grunting, straining and cursing to move before he leant back with a sigh.

“What are you trying to do?” I asked once he’d got his breath back.

“I wanted you to fuck me bigger! But I can’t get in a better position.” He lifted his head, struggling to see me over his chest. “You’ll have to do it like this. Think you can lift my legs?”

My eyebrows rose as I looked down at his legs, his calves alone looking thicker than my waist. With a grunt he managed to lift his legs up but it was obvious they were heavy. I found myself approaching the thick legs framing the ample backside of a superhero waiting patiently for my needy cock. Despite the fact I’d just cum a fair amount to get Jacob this big it was already swelling up again to stretch over a foot long. I had to crouch to get my shoulders under his legs, knees shaking a little from their weight as I essentially did a squat press with them to stand up.

“Please,” Jacob moaned, “please fuck me. I want to be bigger, fill me up and make me grow again.”

He was practically trembling before me with need, his glutes clenching and relaxing, begging for my cock to slide inside. I moved closer, spreading his incredibly firm cheeks and then sliding my dick, already slick with spit, cum and fresh pre, inside. Those massive glutes of his squeezed my cock deliciously as I got into position, the sheer pleasure making my dick tingle and throb. I adjusted one of his legs, gripping them for balance as I started fucking him.

“Oh yes, oh fuck yes!” Jacob panted. The difference in size and sheer density of him meant my thrusts hardly moved a hair on his head, it didn’t matter to him though. The room was filled with his pants and moans coupled with the meaty slap of flesh on flesh. It felt so good fucking such a thickly muscled arsed, it was gloriously tight and… felt like it was getting tighter.

“Shit, I think you’re… growing inside me! Oh yes, yes! Get bigger and then you’ll cum so much and make me grow even more!”

His legs tensed, holding me close and trapping me against him, not that I had any intention of leaving. It felt so good because my cock was growing, and my cock was growing because it felt so good! My balls were filling up as well, slapping heavier and heavier against my thighs with every thrust.

“Fuck you’re getting so big! Oh shit, oh shit, I’m gonna… I’m gonna blow. Please, please cum in me, make me grow before I lose any size by cumming!”

Fortunately I was well on the way. My body shook and I nearly collapsed under the weight of Jacob’s legs and my pleasure as I erupted. Jacob whimpered, he actually whimpered with need as he fought to keep from blowing, not wanting to loose an ounce of mass until he’d grown more. I kept thrusting, even as my knees turned to water, wanting to give him more, wanting to make him as big as possible. Turn him into my own muscle blimp.

When I’d finished, I practically collapsed, folding out from under Jacob’s legs and sprawling across the floor. I looked down to see my cock had shrunk again, but the sight of Jacob’s huge arse and titanic legs above me made it throb and promise it would start growing again. Soon.

“Steve? Steve where are you?”

“I’m here,” I panted, patting Jacob’s shin and pulling on it to get myself up. I crawled up, climbing past his cock until I was straddling his waist, hands on his chest, greeting his hungry grin with a smile of my own. He gave me a wink, flexing his pecs to make me rock from side to side.

“Bet you’d like to fuck these pecs even more now huh?” he asked. I nodded. “Well just wait, they’re gonna get so fucking huge in a second.” He strained his neck, tilting his head to the side to spy down the deep groove between his pecs as though searching for something. “Might want to make your cock a bit bigger too huh? Then it’ll feel real good, fill this gully and let your hot cum funnel down into my mouth yeah?”

“You’re really hungry for my cum aren’t you?” I laughed, feeling turned on and… weirdly powerful. Jacob was a fucking superhero, an icon of mine and now he was huge too. And yet he wanted… needed my cock, needed me to feed him cum to make him even bigger. I rubbed my cock, collecting the cum that was coating it and squeezing a few more drops out too. I let him see the cum on my hand, then slowly licked it from my palm.

“Yes” he growled, licking his own lips. His fingers brushed against my legs, his huge arms preventing him from getting any closer.

I rubbed my cock again, trying to milk out a few more drops when I felt it swell within my grasp. It fattened up to fill my grip, pushing my slick fingers apart. A fat drop oozed from the thickening head and I caught it and brought it hungrily to my lips. I gave my swelling balls a grope and managed to get another helping before Jacob’s whole body trembled beneath me.

“Oh yeas here it comes. Grow… grow… grow!”

Jacob’s traps began swelling up around his head, lifting his head off the mattress as his back thickened beneath him. His pecs swelled up thicker and fuller, pushing against my hands. His shoulders began to creep towards the edge of the bed, growing wider and wider, arms already falling off the edge, kept up from the sheer size of his triceps while they and his biceps grew too big to allow him to bend his arms. His forearms ballooned, his wrist and hands getting buried in the steady avalanche of size spreading out. Behind me I could feel his cock growing rapidly, sliding up my back and threatening to grow past my head. It was a pulsing rod of throbbing heat. I reached back to stroke it, leaning against it and feeling it push back! It was gonna be thick and hard enough to take my weight before long! And still he was growing.

“Bigger… bigger… bigger,” Jacob moaned again and again, eyes rolling in bliss and his grew and grew. I could feel myself rising as the sheer girth of him lifted me up, his abs feeling as hard as steel beneath me, pecs rolling out toward my dick. I rocked my hips, rubbing my back against his cock while shoving my own into his cleavage. My balls were swelling and lifting my dick up as they filled with more cum.

“Can’t… can’t hold it back… anymore,” Jacob grunted. “I’m… I’m gonna…”

Grinning, I twisted myself round, throwing my leg over his chest as I spun 180 degrees to face his dick instead. It was so big now, practically as thick around as I was, beanbag sized balls sprawled across his massive quads. I wrapped my arms around it, kissing the soft, slick head and squeezing it as best I could.

The bed buckled and collapsed under Jacob’s weight, but I didn’t stop making out with his dick. I ground my own cock against his, mine throbbing and swelling as through trying to grow to match this glorious hot monster. I stuck my face into his slit, tongue digging around inside and—

I was nearly knocked out by the first blast of Jacob’s cum. My head snapped back from the blow, his shot hitting the ceiling and then raining down. Dazed and dizzy, foolishly I put my mouth around as much as I could and started drinking.

There was. So. Much. Cum.

I shouldn’t have been able to drink it all. I should have drowned or chocked on it all. But it tasted so good, I was like a starving man getting his first meal in weeks. I NEEDED his cum. Even as my belly began to fill and bulge against the shaft, I kept drinking and drinking. Some part of me registered that my belly was getting so big I was having to lean more to reach the continually firing cock, but not enough to care. Jacob cried out in ecstasy, hardly speaking words anymore just making noises of pleasure. Those cries of pleasure soon changed when he realised he was shrinking, loosing mass with every shot. I couldn’t stop though… I needed MORE!

Jacob could do nothing as I drank up his size, as my body ballooned out with his load. My middle soon grew beyond a yoga ball in size and still I kept drinking, gut swelling. When Jacob had shrank to regain some mobility, he could barely do more than feebly lift a hand to brush against my ample side. Even though he was shrinking, he was still having the most intense orgasm of his life, the pleasure sparking through his body rendering him completely helpless. When he was back to normal and his cock had no more to give, I finally came out of my daze.

“Wha… what?” I gasped sitting up… struggling when I realised I was almost beached on my bloated belly.

What the fuck!?”

My belly was huge. Looking down it was all I could see. I gripped it, by fingers unable to meet each other as I hefted it’s incredible weight, wobbling and waddling to get off of Jacob. I could feel my dick getting pushed down by the sheer size and weight of it, my head rubbing against the tight skin. When I got to my feet, I had to practically rest if on my thighs, unable to stand straight comfortably with it hanging so heavily.

“Whoa… that’s a lot of cum,” I said, absently rubbing it. “You filled me up real good Jacob… Jacob?”

Jacob was out cold. He was sprawled across the broken bed, naked and back to normal size, the corners of his mouth pulled up in a satiated smirk. I bent down to give him a shake, my heart racing, but the sudden movement made me go dizzy. The weight oy my belly pulled me down and I fell onto the bed again. Jacob mumbled something, his arm coming up to hold me while my head rested on his chest.

“Jacob, wake up,” I said, feebly as a wave of exhaustion crashed over me. My limbs felt like lead, my gut felt like a lorry of lead. I’d need Jacob’s help to get up, but since he was having a nap, what would be the harm if I just shut my eyes too? Just for a minute.

My lips were dry and my tongue felt like sandpaper as I drifted out of sleep. My hip joined in with the queue of complaints, feeling stiff from staying in one position too long. Smacking my lips and trying to swallow, I made an attempt to roll over, but something was pinning me on my side. Grumbling, burying my face into the drool covered, hard pillow I’d fallen asleep on, which suddenly pushed up against me.

A low rumble vibrated in my ear before a low, croaky moan was voiced above me. I wasn’t alone.

The realisation was like a cold slap. The fog of sleep was blasted away and the events of last night came rushing back. I pushed myself up with my arms, the weight of my belly keeping me on the bed as I looked down at the sexy hero laying beside me. I hastily wiped the drool I’d left on his chest as Jacob’s eyebrows puckered in confusion, one eye opening while the other scrunched up in the light. He looked round the room with one eye, the other opening gradually and blinking blearily until he found me. Then those dark eyes sparkled and he gave me a smirk.

“Morning,” he said, voice husky from sleep. His shoulders shifted as he shuffled up, frowning again when he saw my huge belly resting on top of his thighs. When the realisation hit though, his eyebrows shot up so fast I thought they were going to fly off. “Whoa…did you tackle a whole buffet while I was out?”

“No,” I said, putting a hand over the bump as though it could possibly conceal it. “You sort of…filled me up.”

“Oh yeah!” Jacob looked down at what I considered a perfect body, but the shadow that flickered across his expression suggested he wasn’t as satisfied. Gently he lifted my gut off his leg, helping me to sit up and then sitting beside me on the edge of the bed. My eyes were drawn to his package as it bounced freely between his thighs, which he spread to let his sack rest on the sheets. “Well you filled me up first so I guess I returned the favour. But…why aren’t you…bigger? Or rather buffer, this thing is pretty big I’ll give you that.”

He poked the firm orb and I giggled in surprise. Smacking his hand away I covered the embarrassing noise by clearing my throat. “Because it’s my cum that causes growth. Yours doesn’t do anything except fatten me up like when Expando sucked off Icarus.”

“True. Any idea what you’re gonna do with it? Expando’s body’s not exactly normal so he could expel the cum no problem. But you…apart from your growing dick and balls and the fantastic cum you make, are you able to…do anything with your gut?”

“How should I know?! This is all new to me you know, my body was perfectly average before yesterday. Sure I used to think it would be nice if my dick was a bit bigger but now it just constantly grows all the time until I…”

I trailed off, suddenly realising something. For so long yesterday my dick had been in a continuous state of arousal. It may not have been hard all the time, just in a perpetual chubbed up sensation; feeling like I was on the way to getting a boner as it grew gradually until I blew my load. But now, even after being unconscious for a few hours, it felt normal. I looked down, my view instantly blocked my new gut, but the fact I couldn’t see it was evidence in of itself.

“My dick isn’t growing,” I said.

“Huh?” grunted Jacob.

“My dick,” I repeated. “My dick hasn’t grown since we passed out last night!”

“And that’s…good?” I narrowed my eyes at the naked hero beside me, he at least had the decency to look a bit sheepish. “Sorry. I just mean, do you think this means it’s been worked out of your system or something? You’re…back to normal now?”

“Maybe…?”

“Well, shit, that’s not what I wanted to hear,” said a new voice.

Jacob and I jumped, or more precisely Jacob jumped up to his feet at the new voice while I just sort of bounced on the spot. I wasn’t strong enough to get up and lift my new gut without a bit more effort. I could still twist around to see the familiar figure in his blue costume standing in the bedroom doorway.

“What are you doing here?!” Jacob all but roared, thudding towards Expando, who took a few hasty steps back. “You’re not supposed to be anywhere near Steve.”

“Yeah, but none of us are—and yet here you are,” Expando shot back. He shamelessly stared at Jacob’s swinging bait and tackle and took in my bulbous gut. “Did you two do it the wrong way round or something? Made the poor guy suck your cock all night to get those little chickpeas to fill him that much?”

Jacob took a swipe at Expando but his torso elongated, twisting out of the way. “Just saying, there are bigger sets around here.” Giggling, Expando stretched out of reach of Jacob, sticking his thumb in his mouth and puffing his cheeks out. At the same time his crotch swelled, filling out like a balloon. He cupped the ample package and gave it a shake in my direction. “See what I mean?”

“Nothing but hot air, as usual,” Jacob grumbled, folding his arms and blocking the doorway. “How did you find us anyway?”

The cocky grin faltered on Expando’s face for a second. He released his crotch as well as he took a more relaxed pose. “You know I can do a bit of detective work too,” he said, somewhat defensively. “I’m not as dumb as you make me out to be.”

“Past experience says otherwise.”

“Stop bickering, you too,” I said, pushing myself to my feet. Fuck, this gut felt weird. My centre of gravity was way off and I swore I could feel the gallons of cum sloshing inside.

Expando didn’t seem to hear me, though. His carefree expression was now hardened in a way I’d never seen before. “Oh, really? Well, shall we see how the golden boy looks when I let Watcher know you went against his orders to sniff out Super Dick?”

“Think you can get past me?” Jacob shifted his stance, still blocking the doorway, arms at his sides, curling into fists. He wasn’t perturbed by his lack of clothing either, standing as strong and bold as though he were in his super suit.

A bit of the old Expando returned, his eyes lightening in a twinkle of his usual mischief. “Think we both know how well I can get you all worked up.”

Suddenly he lurched forward. Jacob spread his arms as though to catch him, but the rubberised hero squashed himself down, coiling on the ground and then like a released spring flung himself through Jacob’s legs and through the door. Too slow, Jacob tried to close his thick thighs in an attempt to trap him, but he barely brushed the dark blue of Expando’s boot. Growling in frustration, Jacob dove after him, phasing through the wall like a ghost. I heard a crash and a scuffle before a door banged open.

“Hey!” I cried, waddling after them. When I got to the door though, my gut bounced off the frame and I nearly fell back. Grumbling and rubbing where I’d caught the door, I lumbered after them again, wishing I was stronger to carry this extra weight.

Lurching I got into the hallway, I looked up and down to see if there was any sign of which way they’d gone. One of the paintings that hung on the walls at regular intervals had been knocked to the floor and there was a crack in the plaster just a bit further on. Guess they went that way.

I followed the few subtle hints of pursuit, my steps getting more and more sure as I got used to the heft and swing of my gut. My thighs were burning as I climbed the stairs, relieved when I came to a door that had been splintered off its hinges. I wasn’t as exhausted as I thought I would have been, this being far more activity than I normally would have done. I could hear Jacob and Expando cursing at each other, following the sounds of their voices until I found them on the floor in… well, they looked like they were in a knot.

Jacob was rolling about the floor, one of Expando’s arms wrapped round his, gripping the wrist tightly in his fist. His other arm was pinned to his side with what looked like Expando’s torso wrapped round him twice. His crotch was covered by what could have been one of Expando’s legs. Meanwhile Expando’s head was waving in the air on a stretched out neck like a serpent, spitting curse words while his other arm stretched down the corridor towards a door on the far side.

“Stop it, both of you!” I yelled, waddling over to the pair.

Jacob’s cock suddenly became more pronounced, pressing against whatever part of Expando was covering it as the rubbery hero tightened his grip. A grunt of surprise escaped Jacob’s curled lips and then—twang. Jacob phased and Expando snapped free, bouncing and unfurling up and onto his feet. He fell back into shape, hitting the ground running to escape before Jacob could recover. The naked hero flopped on the ground, making a swipe for Expando’s foot.

“Got you!”

Ignoring the trapped foot, Expando hopped down the corridor, his leg stretching out even as Jacob tried to pull on his foot, hands reaching to grab more of his elongated ankle. I could only watch, flummoxed as Jacob pulled to no effect on Expando’s leg, enough to almost have a coil of his calf before him, until Expando’s foot wobbled up to kick him feebly on the thigh.

“You’re done for now,” Expando panted as he hopped, looking over his shoulder and grinning in triumph. He was too busy looking behind him he didn’t notice Icarus stepping out into the corridor, no doubt drawn by the noise. He was out of his uniform, in a pair of jeans and a loose shirt with a few buttons on the top undone. His expression started off frowning until his eyebrows shot up and Expando cannoned into him.

Instinctively, the rubberised hero wrapped his arms around Icarus’s neck, causing him to stagger and grip his colleague in support. Expando’s hopping foot bent unnaturally at the ankle,, and suddenly the tension in his stretched leg started pulling him back. Icarus was dragged forward at the same time Jacob skidded across the floor, his bare cheeks squeaking along the floor. The three of them met with a crash and chorus of grunts, ending in a crumpled pile of waggling limbs.

“What the fuck, Travis?!” Icarus yelled, untangling himself forcefully and standing to his feet. He brushed off his jeans, scowling at the torn buttons on his shirt until his eyes fell on me. “I should have known.”

I became very aware how naked I was. I clasped my hands beneath my gut, covering my junk, which fortunately was still a manageable size and therefore coverable. Jacob and Expando…Travis I guess, got to their feet, the former keeping a tight grip on the latter. Icarus arched an eyebrow at Jacob’s cock slapping and swinging between his thighs but made no comment.

Turning his attention to Expando, Icarus sighed. “Considering these two are naked, I assume you caught them at it while you were trying to get some action yourself?”

“I was just doing a perimeter check,” said Expando, his tone fooling no one. “Then I heard something coming from one of the rooms. I investigated and found Density here going against Watcher’s orders with Super Di… I mean Steve.”

“You’re so full of shit,” grumbled Jacob.

“Speaking of being full,” Icarus cut in over Expando’s spluttered retort, “what happened to him?”

“I can speak for myself.” I was getting tired of everyone talking around me as though I wasn’t there. No longer trying to curl in on myself, I put my shoulders back, straightened up and stuck my gut out.

Unimpressed, Icarus arched a brow. “Well…if you can speak, speak. Since you’re not walking around with a penis bigger than you are I’m assuming one of these two are the ‘father’ of that cum baby. And I also assume it means you made one of them grow enough to give you such a filling.”

My flicker of confidence quickly died. I’d put my foot in it now, I’d have to admit that Jacob had snuck into my room, that we’d fooled around and after making him grow he’d emptied his massive balls into me. Then again, it was obvious what had happened anyway.

So I told my tale, Jacob chiming in as well, taking a step closer to me to show he was with me in this. When it came to Expando walking in on us, the rubberised hero rolled his eyes and admitted he’d been looking to “score some of that magic cum” as well. He didn’t exactly come stand with us on a united front, but he was no longer trying to throw Jacob under the bus.

It was impossible to read Icarus’s face, set like a piece of stone as he was once again listening to stories of our sexual exploits; two of us naked this time. When we’d finished, he gestured for us to follow.

“We best update Watcher on this too,” he said, approaching the door Expando had been intent on reaching. “I admit I was experiencing some…cravings as well in the night. I managed to resist, however it does support my theory that there is something about you and your semen that has an alluring quality. Expando may be a horn dog most of the time but I know Density has a good head on his shoulders. Usually anyway.”

“Meh, can’t deny it,” said Expando with a shrug. “At least I got dressed though.”

“You could always stretch yourself into some speedos again,” Jacob muttered, leaning in close to the shorter hero and giving him a playful nudge.

“Rather you face the boss in all your glory.”

Icarus only sighed, opening the door into a high ceilinged laboratory. The machinery and equipment inside put Dr Garner’s stuff to shame, he may as well have been a kid with a ‘my first science kit’. I could only name a few of the machinery in sight, the rest was way beyond me. The other three were used to the lab, walking through the counters without glancing at anything, all making a beeline for something near the back of the lab. However, when we walked round what I assumed to be some sort of cryo chamber, they all stopped and in nearly bumped into Jacob.

“No. Fucking. Way,” Expando laughed. “Look who we caught with his hand in the cookie jar. Or the cum pot I guess.”

“Don’t make a big deal out of it,” Watcher chuckled, licking the corner of his mouth to catch a bit of cum. “It’s all part of my experiment.”

Watcher was… well, he was… huge. His 6’6” frame was absolutely packed with mass and muscle. His pecs made a huge shelf in front of him, reaching a good two feet or more. His traps rose up either side like mountains, brushing his ears and threatening to just swallow his head in brawn. Arms thicker than a normal person’s waist hung at angles at his side, his super suit like a green skin it was stretched so taunt over every bump, curve and bulge. I could even see the veins sticking out clear as day. His back swelled out behind him, not as far as his chest in front but still a far side more than even the biggest bodybuilder could manage. His lats battled his arms for space and his core was all but lost beneath his pecs.

Another thing concealing his core was his crotch. Getting pushed up by a massive set of well shaped balls, Watcher’s cock was draped over them like an anaconda lounging over yoga balls. How his suit was still intact was a mystery, unless his was made of a similar material to Expando’s. It cupped his balls together in a cradle while his cock stretched out that bit further. I could see the ridge of the flared head poking out from the top, the tip of the head pressing clearly against his darker trunks while the rest of the material stretched out from tip to nuts. This beautiful package rested on legs that were columns of muscle, his knees all but lost beneath the heads of muscle of his quads. His calves were like bowling balls on the back of his legs and his pert backside made another shelf behind him, albeit smaller than the superior scaffolding of his pecs.

He looked so dense, so thick with muscle, it almost defied logic that he was still standing. So when this massive mountain of a man suddenly turned towards us, cock swinging like a lance to point the way I nearly took a step back in shock. I looked down and saw his feet hovering a few inches of the ground as he slowly began to drift towards us.

“I see you might be ahead of me,” said Watcher, chatting happily as though he weren’t a massive slab of sex and muscle. Expando was tenting his suit, Jacob was giving him a standing ovation, and even Icarus seemed to be aroused by the sight, though perhaps not as evident in his jeans. “You’ve ingested someone’s enhanced cum I take it?”

Watcher tried to point to my gut, his thick arm rippling like an ocean of strength as he lifted the massive limb. Biceps battled with pectorals for space with the motion, and his cock twitched and throbbed within his trunks.

“Erm…yeah,” I said, a bit lost for words, trying to take all of him in and failing. He was just so wide! “Jacob and I… I, erm, made him grow and I… drank his cum.”

“And has it caused any other changes in you? Aside from that belly of yours,” another tidal wave of muscle rippled as he made a gesture with his massive arm.

“Erm…not really. Just that my cock has stopped growing, at least.”

“As I suspected.” Watcher gave a grunt, trying to reach for his crotch but unable to reach it. His cock throbbed and his trunks darkened as a copious amount of pre leaked out of the massive head. “Forgive me,” he said, a bit breathlessly, “this has made me horny as well as huge.”

“Yeah, about that,” said Expando, adjusting himself. “I thought you said we weren’t to have any of Super Dick’s cum, and then you go and…” he opened his arms, a feeble gesture to try and encompass all of Watcher’s mass.

Watcher just chuckled, his pecs tensing together, just bulging out even thicker, the thick cables of muscle straining pout against his suit. “Like I said, it was all part of my experiment…”


Watcher stroked his chin, deep in thought as he examined the samples in front of him. A small part of him almost missed the days he used to need a microscope to do such investigations—now it was simply a case of concentrating. His eyes gave off a faint green glow as he zoomed into the sample of Steve’s cum. It was brimming with testosterone, way more than was humanly possible. He could also detect an odd arrangement of proteins and enzymes, not to mention a few chemical traces similar to the Body Builder’s concoction.

He switched his attention to a sample of Icarus’. The testosterone levels were high, though not as off the charts as Steve’s. The chemical imbalance of the growth formula was evident too, broken down amongst the enzymes but still active in some way. Nothing Watcher could see gave any indication what such an action it would cause.

The sample he’d taken from Expando had only the faintest traces of the formula. In his past investigations of the Bodybuilder’s previous victims, the formula had broken down considerably more, although admittedly the samples he’d investigated had been blood and saliva, never semen.

Just for the sake of being thorough he’d taken a sample of Density’s cum as well, even though he’d not been exposed to any of Steve’s cum. He had admitted to taking some of Expando’s, not that there was any evidence of it in his system. For all intense and purposes Density’s load looked healthy, if not as in such high quantity as the other samples he’d taken.

Watcher looked over at the rest of the samples. Icarus had the largest tub, having been the biggest when it came to making a deposit. Steve’s was the next although Watcher had only taken a portion of that. Thinking to himself, Watcher walked over and opened the container. As before, when he’d opened the tub, the aroma that came out caused a stirring within the hero. The longer he left the tub open, the feeling intensified, his crotch plumping up into a semi as he became aroused.

“Icarus may have been right,” Watcher said aloud, adjusting himself. There was something about the cum that…drew you in. Watcher hadn’t been with many men before, and those he had he didn’t recall wanting to lap up their cum, yet right now he was actively contemplating lifting the tub and taking a swig.

Coming to a decision, Watcher picked up the tub and carried it towards the back of the lab. He set up some recording equipment, while not as good as his eyes he hoped they would pick up something he could study. Then, taking a deep breath, he lifted the tub to his lips and began to drink.

The sample was thick, and almost…creamy if still as salty as normal cum. He drank it down, his groin tingling already in excitement, so much so he almost struggled to stop himself from drinking it all. He set the tub back down, whipped his mouth with the back of his hand…and then proceeded to lick off what was there. He was acting like a starving man with his first meal in weeks, desperate to get as much as he could and not waste a drop.

“There is definitely an addictive quality to the substance,” Watcher said aloud, studying his hand to both marvel at his actions in licking it clean as well as checking for anything he might have missed. “It’s almost as though it releases pheromones to draw people in to drink it. Perhaps even Steve himself produces the pheromones as well, which could explain Icarus’s behaviour. This suggests some sort of…genetic necessity to spread the formula to others?”

“We know that when others drink Steve’s cum they grow, differently to the Bodybuilder’s original formula, not gaining height but only increasing in muscle mass and genital size. When he drinks it however, it only causes genital growth, as though it causes his testes to produce more of the formula. That does beg the question; why aren’t his muscles affected by the formula? And for that matter how is his body able to reproduce the formula in the first place? Previous evidence has always pointed to the formula being man-made, concocted in a lab rather than having some more organic origin. There must be something about Steve that caused these changes to—”

Watcher’s words trailed off into a moan. His cock throbbed and swelled within his trunks, tingling with pleasure, making his knees quiver. He could feel his balls swell up as well, rubbing against his thighs. He gripped the edge of counter, watching as his forearms rippled and tensed, the muscles jumping out like thickening cables. He lifted his arm, watching the growth flow down into his biceps and triceps, both swelling out in different directions, gaining a few inches, the peak of his biceps splitting into two mounds of power. He relaxed the flex and the heads of muscle on his shoulder rippled and bunched together as they grew thicker too.

Behind him his back began to broaden, the range of bumps and swells of sculpted muscle rising higher, stretching wider into a mountainous range beneath his cape. His chest was heaving with his heavy breaths, swelling with every gulp of air but never going down as far as his pecs became thicker and thicker. He moaned deeply as his core tightened, his six pack developing into an eight pack, the slabs of muscle crunching tightly together at the same time his quads began to thicken. They pushed his crotch out, making his hardon that bit more pronounced.

Struggling to concentrate with the rising euphoria flowing through him, Watcher tried to focus his vision, to see the effects coursing through him. He was pleased to see his powers still worked and managed to delve into his own body, seeing beneath his stretching suit, his writhing muscle tissue, to see what was causing them to swell up so.

The formula was exciting the fibres; rapidly stretching, breaking and repairing them. It was contrary to the pleasure he was feeling, seeing what should have been agony but only feeling ecstasy. It felt so good he couldn’t keep up his concentration, his vision blurring until it returned to normal and he could see his body filling up with more and more muscle.

He had to shuffle his feet across the floor, widening his stance as his quads thickened and rubbed against each other. His whole body felt hot, hard and heavy. Looking down he could see his chest filling out, pecs pumping up like balloons beneath his suit, stretching out fuller and blocking his vision of what was going on below. He grabbed his chest, feeling the give of his thick pecs as he squeezed them, the soft flesh turning to hard stone that pushed back against his grip when he flexed. He was so strong! He lifted an arm, tensing the biceps and watching the peak rise and then fall with every flex. His suit was like a second skin over the rock hard muscles, getting so tight he could see a few veins becoming pushing out visibly.

“Incredible,” he panted, his hand leaving his bicep to feel his very tight trunks. His eyes widened when he felt the new and enlarged organ throb against his caressing fingers. His chin stuck his chest as he looked down, just able to see a rise beneath his pec shelf at what he was packing now. He ran his thumb over the flaring head and let out a low moan.

Too soon he could feel the effects fading, his growth starting to slow. He rubbed his cock through his suit, feeling it stretching over his hip, rubbing against one of the heads of muscle on his titanic quads. He didn’t want it to stop just yet…he wanted to get even bigger.

He grabbed the tub of Steve’s cum and drank the rest of it down, then quickly started scooping out the rest with his fingers and licking them clean. Smacking his lips, realisation came slowly to Watcher as a moment of clarity rang once the tub was empty.

“Interesting,” he mused. “I probably should have taken the time to undress and maybe collect a sample of my own before I got much…b-bigger but…I might be…too late.” Watcher moaned as his growth started to pick up speed again. “Strange, there’s normally a d-delay before the g-growing effects start. Maybe it was close enough to the initial reaction to jump on the-fuck-…flows of the first.”

Watcher started rubbing his cock more vigorously; the slab of meat thickening in his grasp and stretching out in front of him. He could feel his balls trembling as they swelled like balloons, the formula upping his testosterone production immensely. He absently rubbed them with his other hand before bring it to the base of his shaft instead, his dick having grown so big and thick he couldn’t get one hand around it anymore. He could already feel his arms, lats and pecs bulging and rubbing against each other, all of them growing thicker and thicker and demanding more space. He wasn’t sure how much longer he could keep this up.

Breath whistled through his teeth as Watcher teetered on the brink of orgasm, edging himself closer and closer, his muscles feeling like they were cumming as they grew and grew. He could feel his traps coming up either side of his head, his chest stretching out in front of him to take up most of his view. His arms were pushed out, feebly reaching for his throbbing cock, denied by the sheer mass of his arms, lats and pecs. Although he couldn’t touch his cock, the sensation of all his bulk rubbing and bulging against each other was pleasurable in and of itself. He could feel his balls getting ridiculously huge, weighing down on his powerful thighs, hanging full and heavy with cum.

“So…much,” he panted. “Must be…a reason it causes such an…exponential growth.” Despite the sheer depth of his pecs jutting out two feet in front of him, he could see the end of his cock straining his trunks beyond. It twitched and he shuddered, wanting to touch it but too pumped to reach. “Hmm, suppose it’s good I only brought a sample of Steve’s cum rather than the full thing. Although…I imagine the size I’d have reached then would have been…spectacular.”

With difficulty, Watcher lifted a foot and tried to take a step forward. It was difficult; the way he had to roll his thick thighs over each other, the way he had to push against his heavy balls and how they sloshed from side to side, hindering his balance even more. He was also very much aware of his increased weight as well; despite his increased strength, he still felt fucking heavy! He only managed a handful of steps before he had to stop.

He huffed and panted. “Definitely lucky I didn’t get any more, I’d have been completely immobile. Hmm, my vision powers still worked and I still have my cape on…so…”

Concentrating, Watcher activated his cloak. A gift from a grateful sorcerer, it gave him the ability to fly. He felt it billow behind him as though caught in a breeze and slowly he felt his feet lift off the ground. The sorcerer had never mentioned a weight limit, he’d never had any difficult before even when the times he’d had to carry Density or civilians. His current weight however did seem to be putting a bit of strain on his cape, only allowing him to levitate off the ground. Even his movements were somewhat slowed, he had the feeling he was like a muscle balloon bobbing in the breeze.

“So my powers are still active,” he mused aloud, drifting slowly back towards the back of the lab. “Expando is the only one to say he lost his powers after growing. Icarus admittedly never tried to use his, he outgrew his harness so couldn’t use his wings but never tried any of his other abilities. Hmm, potentially it could have been because Expando was already stretched in a different way and therefore couldn’t go beyond his new frame.”

Absently Watcher reached for the tub that had held Steve’s sample. He had to lift it up to see past his pecs to inspect the inside, just on the off chance he’d missed any more. The motion made his biceps rub pleasantly against his chest, pushing the right pec up higher in the process. He smirked, thinking that even if there had been anything left, getting it into his mouth would have proven difficult. As it was, he was sincerely hoping he wouldn’t get an itchy nose.

A shrill squeal broke him out of his idle thoughts. It was the compounds alarm system.

“Disturbance detected on western staircase.”

“Shit,” muttered Watcher, looking down at his swollen and restricting form. He was in no shape to handle any sort of assault…unless the targets stood still and let him sit on them. “Show me the surveillance,” he commanded and started hovering towards one of the large minorities.

The screen came to life, showing something long and blue waving down the middle of the stairway while a naked figure wrestled with it. It only took a moment for Watcher to recognise his colleagues Density and Expando fighting on the stairway; the latter trying to get away while the former harried and hindered him. They eventually spilled out onto the same floor as his lab…


“—Which I guess we can continue now that you’re all here,” continued Watcher. “I’m gonna need help getting back down to a more manageable size.” He wiggled his arms at his sides, trying to reach his cock to no avail.

“Fine by me,” said Expando, marching forward eagerly. Jacob looked to me first before following, as though checking I was alright with him going. Icarus seemed to be having an internal struggle, visibly swaying between joining in and wanting to recoil. Eventually he threw up his arms and began taking his shirt off, muttering about not wanting to get it dirty.

While the heroes flocked to surround the muscle blimp of their leader, I watched, holding my already full cum gut and wondering what to do. I mean, I wanted to join in, my cock was rock hard at the sight of Watcher, and his cock was practically calling to me…but I didn’t know if I was welcome, it looked like a—

“Steve,” said Watcher, his voice a low purr that turned into a moan as the others started to touch and rub his body, Expando wasting no time and going straight for the cock. “I want to see…oooh wow…I want you to…fuck yes harder! Wait, I…I need Steve to…sweet fucking yeah just there, just th-wait! Steve, you’ve got to drink my cum when I blow!”

“I do?” I asked, waddling forward, desperate to join in. Icarus and Jacob were both groping Watchers arms, the pair of them practically grinding against limbs as almost as thick as their waists. Icarus occasionally reached out to squeeze Watcher’s chest, still in his jeans as his groin rubbed along the deep groves of Watcher’s forearms. Expando was on his knees in front, arms wrapped double around Watcher’s cock, pumping it while he made out with the head that was bigger than his actual head, all the while his blue bubble butt rippling as he humped those massive balls.

“Yes,” Watcher hissed through gritted teeth in barely contained bliss. “You need to take it, I want you to take it. There’s more to this reaction, n-need to test, to see. You’ve had some already but…more must be needed. Oh fuck…please, please, suck my dick, drink my cum, I need to blow so much, feels so fucking good.”

I knelt down next to Expando, the rubberised hero moving over to make space for me, giving me a goofy grin before giving me a kiss. His tongue was already salty and slick with Watcher’s pre leaking through his trunks. I lapped it up, kissing Expando harder and lapping at his chin. He moaned. Once I’d had a taste, I needed the real thing. I looked into the massive, flaring head of Watcher’s cock, and got to work

It was surreal, kissing a cock head that rivalled my own head in size. To press my face into the soft, spongy flesh and feeling the hot pre oozing out, my tongue lashing out to catch as much as possible. Watcher’s trunks were already soaked with the stuff, I wanted so bad to get at his cock proper, although I wasn’t sure how I could achieve it. His suit was stretched so tight as it was, straining taunt over the vast expanse his body had swelled into, I didn’t think any of us would be able to get a grip on it, to stretch it it that bit more to get it off him.

Watcher didn’t seem to mind the wall of material in the way. The level and volumes of his moans was more than enough of an indication he was enjoying himself. He was looking at the heroes hanging on his arms, Icarus squeezing the bulbous biceps while a naked Jacob was grinding his cock against the tight horseshoe of his triceps. Watcher grinned, curling one arm to make the biceps swell against Icarus’ grip, lifting his feet from the floor as he curled his weight easily. Icarus moaned and kissed the split peak of brawn. With the other arm Watcher twisted and straitened it, flexing the triceps for Jacob who picked up the pace of his grinding, his cock sliding into the groove the muscles made just above the elbow.

“Fuck my muscles,” Watcher purred, his low voice vibrating in that deep chest of his. “Worship my mass.”

Expando rubbed up against me as he started kissing Watcher’s cock with me, his rubbery arms still stretched to wrap around the shaft far too thick for a hand to grab. He pumped it with his arms, rolling his hips to grind against his colossal balls in front of us. They were a sight to behold, so big, round and firm. My belly, filled up from earlier by Jacob, was practically eclipsed by the huge orbs, and it felt so good feeling them rub together. I wanted them to unload into me, wanted to get filled up by them so bad.

“Mmm, yeas!” moaned Watcher as I became more eager in my attentions. I was practically pushing Expando out of the way to get my tongue and nose buried into the slit, gripping the head in my hands and rubbing the sensitive glands to make the muscle blimp shudder. “Yes more, more Steve, make me cum, I want you to have it, to drink it all!”

Icarus was practically climbing onto Watcher, scrambling from his arm to sprawl across his chest. Watcher grunted slightly, taking Icarus’ weight as the jeans clad hero planted his feet on Watcher’s titanic quads. The rattle of Icarus’ belt buckle coupled with his heavy breathing as he opened his jeans and shoved them down. His pert backside was on display, the firm glutes rippling as he started fucking Watcher’s chest, gripping onto his mountainous traps to keep his balance.

“Yes,” chuckled Watcher, tensing his huge pecs to almost swallow Icarus’ cock in a sea of muscle. “Harder!” He tried to reach for Icarus with his hand, but his biceps and pecs couldn’t let him reach, the dense muscles bulging against each other, neither giving and inch.

Jacob had his arms wrapped around Watcher’s, groping biceps and forearms, still thrusting his cock against the tight triceps. He kissed the solid, multi-headed delt, bitting into it as his body tensed and he came, his grip tightening on the massive arm as his legs turned to jelly at the intensity of his orgasm.

“Yes cum on me! Cum from my muscles!”

Watcher flexed his whole body, his already huge muscles pumping up that much bigger. Jacob lost his grip, falling back into the floor, ropes of cum still firing to rain down on himself. Icarus’ thrust slowed when Watcher’s pecs gripped his cock even tighter. Expando was humping those massive balls, frantically pumping the shaft as fast as he could. I had my face practically buried in his slit, squeezing and rubbing the head in my hands.

Fuck!” Watcher roared. His head flared, his whole cock thickening even harder, his balls tensing in. “I’m gonna cum!!”

I braced myself, gripping the cock head tight even as it flared against my grasp. The first shot hit me like a train. The load firing out of such a colossal monster cock was too much for my normal mouth so most of it spurted up and out and everywhere. I felt the hot seed splash down my chest, over my face, heard it splatter on the floor even over Watcher’s cries of bliss. I’d barely swallowed the meagre portion of the first load before Watcher rocked and the next one came, just as thick and fast as the first.

I didn’t get a good seal on his cock until the fourth or fifth volley, in that time Icarus found his climax above and all but collapsed on top of Watcher’s pec shelf. I could hear Watcher’s moans become muffled as Icarus began kissing him, still grinding his leaking cock into Watcher’s pecs.

Once I had a lock on his cock, a feeling familiar to when I’d suck Jacob off began to flow through me. I drank down every shot, letting its warmth course through me and pool in my gut. I could feel it expand and swell with every swallow, making me feel tight and full but I still wanted more. I became aware Watcher was starting to shrink when I could feel his cock almost drawing away from me as it deflated, emphasised somewhat by my gut inflating and almost pushing me away. It had grown so big it rested on the floor, covering my thighs as I knelt on the floor. I had to shuffle and push it forward to keep close to Watcher’s cock as he shrank back down.

I was so focused getting on as much cum as possible I didn’t notice when Icarus climbed down from Watcher once he wasn’t big enough to rest on. It wasn’t until Watcher brushed my cum slick hair back that I realised that he was back to normal and I had his cock almost completely in my mouth. I drew back, releasing his cock, still covered by his trunks, his suit hanging a little loosely on his body after being stretched so much. I realised everyone was looking at me, all in varying degrees of clothing and cum covering. I looked down and nearly passed out.

My gut was huge. I was resting on it, this massive orb, tight as a drum jutting out from me, leant forward slightly, partially standing as it lifted me too high to kneel and was too heavy for me to lift to even try and stand. My arms couldn’t reach all the way around it it was so wide.

“Oh my god,” I breathed, making a feeble attempt to stand only to give up when I realised it was impossible. “What…how is this possible?” I asked, sputtering as I craned my head back to look up at Watcher.

“How can you make us all cum obsessed muscle blimps?” Watcher retorted.

I felt my stomach drop with dread. Had this been Watcher’s plan? To turn me into a fucking cum balloon? To be too big to move on my own as a way to incapacitate me? I tried again to stand, my feet struggling to find purchase, my cock and balls flopping and slapping against my gut. All my flailing achieved was to roll and wobble in place.

“Hey, easy, easy now Steve,” said Watcher gently, putting his hands on my gut so I didn’t roll over and get pinned under it. God just the thought of having all that weight on me… “I was only meaning that your body has gone through a significant change so you’re going to have to adjust your expectations of reality a bit.”

“You’re in good company for that,” said Expando, for once sounding sincere rather than joking around. It was marred somewhat by him stroking his hardon under his suit. “We’ve all experienced things like this.”

“Now the reason I made you ingest all my cum is that I think you’re body needed it to develop itself further,” Watcher continued. His eyes were glowing green as they roved over me, his head nodding ever so slightly. “Your cock was continually growing from your first exposure, but once you had some of Density’s cum that stopped. Now you’ve had some of mine, hopefully that will mean—”

Gah!”

I cried out, gripping my gut as it suddenly cramped up. I felt it pulse and tighten beneath me, Watcher and Jacob coming up on either side to hold me as I shook in place, keeping me from rolling over. My stomach felt so full, so tight, I thought I was gonna burst.

As quickly as the pain had come on it faded off just as fast, leaving me panting. It wobbled and rose and fell with my breathing, slowly noticing that I was gradually going down. My gut was deflating, although where all the cum was going I had no idea. Then I remembered that first time Expando had drank my cum, his basketball belly had suddenly deflated, and then he’d grown. Was that going to happen to me? Was I gonna get huge next?

I sat back on the floor once my gut had shrunk back to a more normal size, Jacob coming up behind me as support, dark eyes wide as he watched my gut recede. Once it was completely gone and I was back to normal, I put a shaky hand to it. As far as I was aware it felt normal. I looked down at my arms, my cock, my legs, everything looked normal, and by that I meant small when surrounded by all these huge heroes. Feeling self-conscious I crossed my legs and covered my groin with my hands.

“So…” I hedged, “am I…back to normal now? Has the serum worked through my system?”

Watcher squatted down in front of me, shaking his head. “I’m afraid not Steve, it’s still in your system, albeit a bit different than before. I wonder…could you…would you be able to sort of…imagine yourself getting bigger?” My face must have been a picture the way Expando laughed and Watcher smirked. “I know, it sounds odd but if you could try?”

“I don’t know how to though?” I sighed, looking down at my arms, my skinny arms and trying to imagine them swelling up. When nothing happened I threw my arms in the air and got up off from the floor. “Nothing happened.”

“Hey, it’s okay,” said Jacob gently, putting a supportive hand on my shoulder. “Take a breath for me first of all. Now, when I use my powers, I sort of, tense up, flex my body so my body becomes hard. Maybe if you concentrate like that, flex your body and that might help you concentrate better?”

Jacob ran his large hand down my arm, easing it up and bending it like I was gonna flex my biceps. His hand easily encompassed my skinny limb, it looked down right twig like next to his branch of an arm.

“Biceps should be easy,” he explained, “just bend your arm, flex and concentrate on it. Try imagining it blowing up, like a balloon.”

“Or like you made us blow up!” chuckled Expando.

Icarus snorted. He’d drifted away from the group, awkwardly putting his cock away and searching for his shirt. Despite his apparent disinterest, the show he was putting on of grumbling about the cum on his abs felt forced. It was as though he was doing his best to be looking anywhere but at us. The rest of the heroes were giving me their full attention; Watcher with a scholarly gaze, Jacob in support and Expando in… hornyness.

I closed my eyes, trying to ignore them as I took another deep breath. I then opened my eyes and focused on my bent arm, at the bump that was my biceps. I curled my fingers in to make a fist, tensed my arm and tried to visualise it getting bigger, to imagine it getting as big as Expando’s. He was the less built of the team, still easily outsizing me by a few inches, but at least felt like a more achievable goal.

When I tensed my arm, there was a twitch of movement, compared to the biceps I’d seen in the past few days, some getting bigger than my head, it was a disappointment to see. Jacob’s reassuring presence kept me going though, I focused and concentrated, imagining the fibres of muscle under the skin and picturing them getting thicker.

A tickling sensation on my stomach broke my concentration. Surprise made me gasp and shudder. “Ugh, sorry, I don’t think it’s going to work.”

“Maybe you need more cum,” suggested Expando. “I volunteer to fill you up, once you grow me first of course.”

“Hang on,” said Watcher, waving for Expando to calm down. “I think it did work. Look.”

Following Watcher’s intense green stare, I looked over my body. After a few seconds of not noticing anything, I looked back up at him. “What am I looking at? I don’t have your eyesight.”

Watcher chuckled. “Fair point. I can definitely see increased musculature. Did you feel something? It looked like you shuddered at one point?”

“Yeah I just felt this…it was a bit like when your stomach drops but not as intense?”

“Try again, but this time keep going.”

Swallowing, I got back into position, studying my arm. I still couldn’t see what Watcher apparently could, my body still looked the same to me. Maybe a bit of a shadow to suggest more mass? If I squinted and hoped. Negative thoughts aside, I tried again, concentrating.

Once again my stomach did a little flip. This time I didn’t break my concentration, just kept focusing. The tickle eased and I felt a…flow. Something like energy began to creep through my body, making my body tingle with an almost electric sensation. It spread out from my core, pooling in my groin in a very pleasant way before pulsing out in waves through the rest of my body.

“Keep going,” encouraged Jacob behind me, hand rubbing my back, “you’re doing it!”

A grin spread across my face when I could see Jacob was right. My arm was getting thicker. I could see the fibres of muscle writhing under my skin, tensing and relaxing, getting bigger with every pulse. My skinny arms were now becoming thicker, looking like someone who had a more physical lifestyle.

I checked the rest of my body; my chest was a bit firmer and better shaped, my core was tighter, a faint line running down the middle, legs looking thicker and more sturdy. Encouraged by my success I tried to pump myself even more.

“Wow, look at you grow,” Expando chuckled.

I couldn’t help but grin wider as I flexed my body, watching it becoming more built. The energy coursed through me with an almost euphoric edge to it, my body feeling stronger and more powerful with every second. My cock was chubbing into a semi and I could feel my balls starting to swell and tingle. My junk seemed to be getting more of a boost than what was flowing through my body, as by the time I’d reached the lithe, sculpted form or a swimmer my cock was considerably bigger and balls heavier by comparison. Expando’s arm stretched to snake around Watcher so he could cup my balls fondly.

“Leave him alone,” Jacob grumbled, even though his hand had been rubbing my rippling back the whole time. It had started to slide down lower, fingers brushing the rise of my pert backside. I shifted my stance and felt his cock poke my hamstrings. Feeling daring I slipped a hand behind me to grip it, earning as low moan and a rush of breath on the back of my neck. I then concentrated and made my balls go from egg sized to a pair of full oranges in Expando’s grasp.

“Shit!” he laughed, my nuts practically spilling out of his grasp. He fondled and felt the heft of my sack while I leant back against Jacob, twisting my head to his face and kiss him.

“Steady now,” said Watcher, though his voice was a bit breathy. “No need to start…anything too…” He trailed off, Expando stepping up next to him and nodding down at the tent in his cum soaked trunks.

“You were saying? Why don’t you take that suit off and we can start cleaning you up.”

With remarkable willpower, Watcher shook his head. “Steve, you need to stop this. Try and rein in your pheromones.”

I was only half paying attention to him, resting in Jacob’s arms, kissing him and stroking his cock behind me. It wasn’t comfortable, it felt good, just awkwardly twisting my arm to rub his hardening dick. I really wanted to get it inside my butt, let him feel how hard and firm the cheeks were now. I felt my glutes swell out a little bit more, becoming even tighter and more rounded. Jacob growled his approval, arms around me squeezing me tighter.

“Steve,” panted Watcher, even as Expando began groping his green trunks, “you need…need to…st…make us bigger again.”

“Yes, grow us again,” Jacob panted, breaking the kiss to breath those words, heavy with need before kissing me again. “Make me bigger, grow me huge.”

“Grow these balls for us,” Expando chimed in, still fondling my nuts. “Make them huge so you can make us titanic. Make us immobile muscle blimps, just make me the biggest.”

“No, make me bigger.”

“I want to be the biggest.”

The three of them closed in on me, kissing and touching my body, stroking my cock. It started growing in its own, plumping up thicker and thicker, balls swelling like heavy water balloons. I didn’t even have to concentrate on them, the frenzy of the moment was making them grow on their own. I thought about making myself a bit bigger, felt the energy flow but it was shaky, hard to maintain, so I gave up. Feeling my cock and balls grown felt so much better though.

“Enough!”

A thick, cold substance splattered against my thigh and groin, sending a jolt of shock through me. Watcher, Expando and Jacob cried out around me too and we bumped and crashed into each other as we instinctively shied away from the cold foam being sprayed onto us. We tried to separate, Jacob and I slipping barefoot to land in a pile while Watcher hovered out of the way and Expando managed to keep his balance.

Icarus was holding a fire extinguisher aimed at us, giving it a shake to dislodge the last of the foam before setting it down in the floor. He folded his arms, his usual scowl of disapproval aimed at me.

“Good idea, Icarus,” panted Watcher, brushing the foam off of his chest.

“Not the white stuff I was hoping to get covered in,” grouched Expando.

“I wouldn’t have needed to do that if you all listened to me. He’s making us all horny crazed idiots!” Icarus looked like he wanted to march up to me but was doing his utmost to keep me at a distance. He only glared as Jacob helped me up, the pair of us naked and covered in clumps of foam. Parts of it were drying already and it felt very uncomfortable.

“While your quick thinking is appreciated your snark isn’t,” said Watcher, his words clipped and his eyes hard. “Steve isn’t at fault, he is experiencing new abilities and doesn’t have full control yet. You think we should lock him up, put him in isolation until he somehow learns how to use his abilities?”

“Better that than have something go wrong and we can’t help because we can barely move from muscle and cock! I’ve still not repaired my wings from when he made my pecs swell out and snap my harness.”

“Then perhaps your time would be best spent in the workshop while we help Steve.”

The chill in Watcher’s voice made me half expect to see my own breath. Even Icarus seemed somewhat taken aback. He quickly recovered, knocking the fire extinguisher over as he stalked past us.

“It’s our job to help people Icarus.” said Watcher.

Icarus stopped in the doorway, the muscles in his back knotting as he fought to keep from turning around. “Hope your next orgy doesn’t get you so big you break through the floor.” he finally said before leaving and slamming the door behind him.

Watcher let out a long sigh. “I’ll have to talk with him later. Preferably after I’ve showered.”

“He’ll be fine,” said Expando with a flick of his hand. “He just needs to swap that stick up his ass for a dick. Think you can show Mr Sunshine to have some fun Super Dick?”

Jacob groaned and rolled his eyes behind me. I looked down at my dick, hanging at half mast a good few inches out in front of me, I’d guess at a foot and a half with my ample sized balled resting on my shapely thighs. Super Dick indeed.

“I’m sorry about this,” I said, gesturing at my dick, Jacob in his nakedness, Watcher in his cum covered suit and the foam splattered over the lab. “I get what Icarus is saying, I am causing a bit of havoc.”

“Not on purpose though,” said Jacob kindly. “You didn’t ask to get these powers.”

“And like I said; you’re still learning,” offered Watcher. “You’ll learn to get a handle on your pheromones, I know who we can call in to help with that.”

Jacob and Expando groaned. “Do you have to call him?” groused Expando.

“Do you know anyone else with a similar power?”

Expando scrunched his face in true thought, grinding his teeth until his shoulders slumped. “Okay fine, guess he’s the only real option, I still don’t like it though.”

“Duly noted. I’ll make a call, last I heard he was in the area.”

“Who are you calling?” I asked.

“Tom Alley.”

A figure in black spandex sprang to mind. His suit clung tightly to a fit body; broad shoulders, narrow waist and perhaps the most pert and shapely backside on the planet. Whenever there was a picture of him from behind, those globes instantly drew the eyes. On the rare occasion there was a picture from the front, it was his hairy chest that would be noticed first, peeking out of the low neckline of his shiny suit. Once you could lift your eyes up, you were struck by a cocky smirk framed by rough stubble, mischievous eyes peeking under messy dark hair. He had that “just rolled out of bed” look down to an art. Unbidden, the thought of him kneeling before me, shoulders lifted to let me look down his suit as he opened his mouth eagerly for my cock began to form in my mind and my cock reacted.

I felt Jacob tense beside me. “Damn,” he grunted, slowly taking a step back. “I really want to jump you right now.”

“Sorry,” I said, widening the distance between us and pushing my dick down as though that would help. I focused on it, trying to imagine it getting smaller, willing it to a more manageable size, but it just bobbed and swayed in front of me, here to stay. “Guess I can’t make it go down.”

“Can you make your body shrink down?” asked Watcher. “Just to see the extent of your control.”

I didn’t really want to shrink my body, I kind of liked looking fitter, especially being surrounded by all these hunks in super suits that clung to sculpted forms. Watcher’s request was reasonable though, merely tinged with curiosity to see what I could do, was hard to not want to go along with what he asked. I took a breath, closed my eyes and found that pol of energy within me.

I imagined drawing that energy out of my body. The sensation started off cold, my muscles feeling tight and strained for a fleeting second, before I felt a bloom of heat and pleasure in my groin. I opened my eyes in surprise, in time to see my cock throb bigger and my balls swell fuller.

“Shit,” I cursed. “Well, I can shrink my muscles down, but it goes straight to my junk.”

“Bet you’ll have to cum to get that to go down,” said Expando, rubbing his chin in mock thoughtfulness and eyeing me like a mechanic at a pricy fix up and trying not to look to eager. “Guess I’ll have to help with that.”

“No,” said Watcher simply. “We don’t need to test that part any more today.”

“Tomorrow then?”

Watcher just laughed. He went over to one of the large computer screens and tapped at the keyboard. “There; I’ve messaged Tom, hopefully he’ll get back to me and…” he trailed off, something in the screen catching his attention. He tapped and clocked a few things until a message came up. “Shit.”

“What’s up?” asked Jacob.

“We need to move. Everybody wash up and suit up.” Watcher came over to me but stopped before getting to close. “I need you to go back to your room, do you remember the way?”

“Yeah I do,” I stammered. “What’s happened?”

Watcher hesitated for a second. “I’m afraid there was a break in at one of our secure hospitals and…and I’m afraid your boss Dr Garner has been… taken by the Body Builder.”

Density felt bad about leaving Steve behind, he’d looked so crestfallen when he found out about Dr Garner. It didn’t help that Density felt guilty, as though he’d let Steve down. They were supposed to have been protecting him from the Body Builder, they’d taken Dr Garner to somewhere that was supposed to be safe, and instead they’d let him get taken.

The Body Builder had been uncharacteristically subtle with the kidnapping; his usual MO was to barge in with some poor bystanders as his tank, get what he wanted and then grow a few more people as a distraction to slip away. This time he’d entered by some unknown means and it wasn’t until one of the cleaners came across a nurse in tattered scrubs unconscious in one of their supply closest with a naked guard that anyone realised something had happened. After the hospital had done a security sweep, they found that Dr Garner was gone.

Icarus and Expando were searching the perimeter, seeing if there was a trail they could follow; hopefully he’d used a larger than average guy to help him carry Dr Garner out. Expando had thought it more likely he would have shot the doc up and ordered him to walk himself out. It was a potential lead however and deserved a look.

Density had joined Watcher, examining first the scene where the nurse and guard were found as well as interviewing them. The pair had no memory of what happened while they were under the influence, but both seemed shy and embarrassed when asked about the other. There was damage to the shelves and walls in the supply cupboard and a lot of cum splattered about the place. Density wasn’t sure if it was his own filthy mind but he had a feeling the pair might have been instructed to wait in the cupboard until the serum wore off, and had probably fucked while they waited. Once injected by the serum, the victims often gave into simple base desires, and their libido had been known to skyrocket when in such an enlarged state.

Just thinking ‘enlarged state’ made Density think back to last night, when he’d been on his back, so pumped with muscle he could barely move while Steve fucked him with his massive cock. Then when Steve came and he’d grown even bigger…it was such an indescribable sensation to feel so big, so fucking strong, to feel all of his muscles bulging and rubbing against each other, and yet with all that power, he was practically pinned by it, made weaker by his incredible strength.

To chase away his rising dick, Density pushed all thoughts of Steve and being filled with his cum out of his mind. He searched the door they assumed that the Body Builder had left out of and then retraced the most likely path he would have taken from Dr Garner’s room. Despite the heavy level of security in the facility, there were a lot of blind spots the Body Builder seemed to know to take advantage of.

Once back in Garner’s room, he found Watcher examining a spot by the window. His eyes glowed an intense green which faded as he pulled back and drew himself up. Density found himself looking over his teammate’s body; his suit fresh and clean after this morning’s escapades, but still tight and revealing. He felt he could see the outline of Watcher’s cock more than normal and began to wonder if his thighs had always been that thick…

“Density?”

With a shake of his head, Density pulled out of his horny thoughts and brought himself back to the hospital room. “Yes, sorry I was…just thinking this was an inside job.”

“I think you’re right,” said Watcher, ignoring his teammate’s ogling and obvious boner. “How he could have known Garner was here let alone what room he was in. Someone must be in his pocket. This could be advantageous to us though.”

“How?”

“We’ve often wondered how the Body Builder could access the chemicals for his formula, perhaps one of his sources is here.”

“Which could hopefully lead us to his base if we find his contact.”

The door opened and one of the doctors poked his head in. “You asked to see me?”

Watcher waved him in. He shuffled in, looking a bit nervous. Density guessed he was in his late 50’s, thinning hair and an expanding middle, he was a few inches shorter than the heroes and even seemed to shrink back in their presence. “You were one of the doctors overseeing Garner?”

“Y-yes,” he said, adjusting his lab coat and fidgeting. “I saw him last night when I started shift and then noticed him missing this morning before I could—before I left.”

“Did no one check on him in the night?” asked Density.

“I had rounds elsewhere. It was Clark’s shift last night, he’s the nurse I believe you found in the supply cupboard. You’d be best checking with our Matron to see what time he was due to come in here.”

“How was Garner’s overall health?” queried Watcher.

“He erm…had a mild concussion. I understand he was struck during the original attack.”

“Did he ever regain consciousness?”

“Y-yes, but not until the evening.”

“Did he say anything? Was he aware of where he was?”

“I managed to m-make him aware of his situation, he seemed to t-take the information in. He was m-mostly concerned about his w-work.”

Density frowned. The doctor was being oddly nervous. On the one hand it could be understandable nerves after having a supposedly secure facility being so easily broken into and having one of his patients kidnapped. However, the way the doctor couldn’t seem to stand still; the constant shuffling of his polished shoes, the way he fiddled with the expensive watch rotating it around and around his wrist…

“What did he ask about?” Watcher pressed. It was hard to tell if Watcher had noticed the doctor’s discomfort or not, but it wasn’t just his X-ray vision that made Density avoid playing poker with him.

“J-just that he was…concerned about the b-break in and everything.”

“Did you run any tests on him?”

Density watched as the colour slowly began to drain from the doctor’s face. He had to swallow twice before he could speak. “Y-yes we did a few r-r-routine checks on him as standard. W-we we’re going to do some m-more today b-but obviously not anymore.” He gave a nervous laugh, a bit too loud to have been genuine.

Watcher merely nodded. “Did he ask for any tests at all?”

“W-w-what do you m-mean? We of c-course ran s-simple tests t-to check his overall h-health,” he repeated.

“How were his genitalia?”

Density moved to block the door just as the doctor began to back away. Although he didn’t really need to, he tensed his body, his muscles hardening to be stronger that steel. When the doctor bumped into him, Density didn’t even sway.

“He made me do it,” blurted the doctor. “I had to do what he said otherwise he would… Please, I had no choice!”

“Why don’t you tell us what happened,” said Watcher calmly, not having moved and waiting patiently for answers.

The doctor turned his head, looking up at Density from the corner of his eye, who simply folded his arms, pushing up his purple pecs and making his arms bulge against his suit, it creaked with the strain. The doctor swallowed.

“Everything I said was true… except…while he was unconscious, his…genitalia was growing. No one had really noticed, even I thought it was just his bed sheets rumpled in a suggestive way. I suppose it was fortunate he was in a gown and hadn’t outgrown his underwear. It was like a third leg, almost reaching the foot or the bed.

“He woke up while I was…well I was gawking to be quite honest. I managed to get him to focus on me, informed him where he was and what had happened. As soon as I’d mentioned the attack, he’d looked down. I’d not quite put the sheets back properly, so he could see the head of his member poking out, a massive python. He then started blabbing about his work and how it had all gone wrong.

“I managed to calm him down, promising to get a sample of his semen he was insisting on testing himself. How he expected to do anything with that ridiculous…Any way, I reassured him, got him to stay in bed and made sure no one else went in to see him. I…I then contacted…him.”

“You have a direct link to the Body Builder?” gasped Density. Surely they couldn’t be that lucky?

The doctor proved him right by shaking his head. “Not exactly. I have a way of sending an alert when…when I have access to materials he needs and used that to let him know where Garner was. I…I didn’t expect him to be so rapid in his actions.

“I’d gone back to Garner’s room, a sample pot for him to keep him placated and found…well, I didn’t expect with his member that size that he could get an erection, but when I walked in… it was nearly at the ceiling! He’d kicked the bedsheets off and I actually saw his testicles growing, they were like water balloons connected to a hose, except they were getting as big as basket balls. He was stroking himself, pawing at the nearly person sized member saying his balls started growing while he was trying to get off. He started moaning that he felt like he was cumming but it just made his balls grow bigger, as though they were swelling from the production!”

Density ever so slightly shifted to try and adjust his own chubbing dick. Thankfully the doctor was stood in front of him, although with Watcher that was hardly an obstacle. Speaking of Watcher, the green clad hero discreetly tugged his cape over his leg, not before Density saw those bright green trunks hugging against a throbbing semi. It seemed they were both getting turned on by the doctor’s story.

“He was…he was so swept up in his lust, he begged me to help him, said it was so big he couldn’t touch enough of it. He started hugging it, wrapped his arms round it like another person! I… I was so overwhelmed I started coming towards him. I felt…drawn to him, like I wanted nothing more than to help him find release. Before I could reach him though, that was when Clark came in.

“I panicked, thinking I’d been caught and you would find out about his change, but then I noticed how tight Clark’s scrubs were. The sleeves were digging into this arms, there was more of his neck and chest poking out of his collar and…and I could see the outline of his package more than usual. That was when I noticed the Body Builder coming up behind him. He barely took notice of me, eyes only for Garner’s member.”

“Did he say anything?” asked Watcher.

“I just heard him sort of talk to himself and say ‘So that’s what you did aye?’. But before he could say any more, Garner started to cum at the same time one of the guards came by the door.”

“The guard couldn’t do more than gasp before Clark dragged him into the room and shut the door behind him. The guard stumbled into the foot of the bed, falling face first into Garner’s balls. That made him cry out in pleasure and the cum started flowing.

“It struck the ceiling and rained down on the guard. That first volley just costed his head and shoulders, driving him back into Garner’s balls again. It splattered on the floor and he slipped and fell. He started frantically wiping it from his face, gasping for breath. The Body Builder made a gesture to Clark and he put his hands on the guards cum covered shoulders.

“And then the guard started growing.”

The doctor took a breath. “He sort of just…leant back, he would have sprawled across the floor if Clark hadn’t been there. Instead, the guard just melted into his arms and I saw his chest swelling rapidly against his shirt. He started moaning and writhing on the floor, groping his crotch as it too began to swell like he had a balloon stuffed down there. His thighs were stretching his trousers, biceps growing against his sleeves and then buttons started popping off his shirt. All the while Garner was still cumming, his cum drenching the bed and pooling on the floor. The Body Builder smacked me with his stick and told me to get back, barking at Clark to get the guard away from the pool.”

“He must have thought the contact was causing the growth,” said Density, trying to will his boner away to no avail. “The guard must have swallowed some.”

Watcher stroked his chin. “But the growth came on a lot more rapidly than…what we’ve witnessed.”

The doctor looked between Watcher and Density, confused. “No, it was defiantly contact that caused the growth, Clark started growing once he got his hands on the guard’s cum covered shoulders.”


My cock was getting easier to aim after the third shot, once it had started shrinking down to a more manageable size. I’d been testing out my new…powers I guess (feels weird even just thinking that)…and how much I could change my body. It was becoming easier to change my body, easiest of all was adding size to my muscles, bulking myself up. I had to concentrate to make myself more defined, like a bodybuilder draining any excess fluid to make the muscles more pronounced. I found I could even make myself more vascular as well if I wanted.

While Density and everyone had gone off in search of Dr Garner and the Body Builder, I’d been left to my own devices back in the room I’d been given. I decided to get some practice and testing what I could do. Making myself taller however was even harder. I really had to concentrate and almost strain myself to creep up a few inches. The effort had left me a little breathless and I’d had to take a break for a minute. I wondered if I’d had anything to do with what my cum did to others; the fact it mainly focused on their muscles, not really making them any taller just turning them into immobile muscle blimps. Perhaps because of that limit I could only affect my muscles too.

All my playing about with muscles, vascularity and height though had made my dick and balls grow disproportionately larger. Every time I made my body grow a portion of that growth went there, and then any time I went to shrink back down, the mass I’d gained seemed to go straight to my groin. So when I went from a hulking bodybuilder sized version of me, and then decided to shrink back down to more of a well shaped gymnast, it left me with a cock nearly 4 feet long and balls hanging like beanbag chairs from my groin. I almost bulked up my legs to help with the weight but that would have only made them grow even more.

Hence why I was currently shooting my load into the bathroom, standing outside the doorway because my balls were too wide to fit comfortably through the door and my cock was too hard for me to aim properly. Most of my shots ended up oozing down the walls to puddle on the floor, only a few globs making it into the basin or the bath. It was nice seeing the new muscular version of me pumping my ridiculously massive shaft in the mirror, at least until it too got caught in the splash zone and rivulets of cum began to cover it.

Once I was done cumming, I walked in, ignoring the squelch of my hot cum underfoot and wiped the mirror clean…ish. Through the cum streaks I smiled at the new me, my still normal face atop someone else’s body. It was weird seeing my neck thicker, the swell of traps either side when none had never existed before. My clavicle was no longer the bony protrusion but now was a swell of muscle. I didn’t know how to bounce them so just put my fist under one of them, pushing the soft muscle up and then letting it fall with a jiggle. It was a weird sensation, feeling that weight on my chest and the heft behind it. I tensed the muscles, making them hard and solid. It felt good.

“Well, you must be the new kid.”

I managed not to slip on the pools of splooge at my feet as I spun around at the new voice. It was a rugged voice, a rough purr like a distant avalanche that promised to sweep me up. Before I could even attempt to hide my nakedness however I was awestruck with the owner of that voice.

Tom Alley was leaning against the doorway in his shiny black suit. He was sex in latex. He was giving me such a confident, cocky smirk beneath his tousled hair I felt my knees go weak. I would do anything for him.

My eyes ran down his tight body, the hairy chest visible through his open zip, his narrow waist, his ample crotch shinning in the light. His hand slid silently up his thigh, giving that bulge a rub and squeeze, hefting its weight suggestively. I felt myself being drawn towards him, ready to kneel before him and let him use me for his pleasure.

Suddenly my head was clear again and I found myself blinking stupidly. I was halfway down to kneeling in front of Tom and nearly fell over, not remembering when I’d moved to get in this position in the first place. I straightened up, shaking my head to try and clear it, all they while Tom still smirking down at me.

“That,” he purred in his low voice, “was your first lesson.”

My mind was still reeling, struggling to take in the stunningly handsome man in the tight black latex suit leaning so casually in the doorway of a bathroom I had just coated in cum to get my once 4 foot long cock down to a more normal size. I vaguely remembered wanting nothing more than to kneel before him and suck his cock before cognitive thinking kicked back into gear. The stranger, Tom Alley, was kind enough to give me a few seconds to regain my composure, watching my eyes intently until he gave a nod when he saw I was back to my senses.

“How…how did you get in?” I asked, words a bit slurred so I sounded stupid.

“The door.”

“Well, yes but…how did you get into the Warden’s base though? Density said they were locking it down while they were out.”

“I’m very good at getting into tight spaces. Case in point.” Tom gestured at his suit, which was so tight it looked painted on in places. He was nowhere near as bulky and brawny as Density or Watcher, closer in size and build to Expando, if a bit more aesthetically pleasing. He turned his back on me, showing off his perfect backside as he swayed his hips way more than was necessary. “Watcher said you needed a teacher and I thought I’d come over whilst I was nearby.”

“He said you wouldn’t be here until tomorrow,” I said, frantically following after him whilst simultaneously looking for something to cover myself with. For the past few days I’d been naked more than I’d been in my entire adult life and I was getting pretty sick of it. Perhaps no one was taking me seriously because my dick was constantly flopping in the breeze. “And Expando had laughed and said—”

“—only if we’re lucky?” Tom finished with a deep chuckle. He sighed. “What can I say? I wasn’t really doing anything, I was a little bored to be honest, so I thought I’d nip on by. I didn’t expect to find everybody out and I was hardly just going to trek all the way back once I’d got here. So, I let myself in. We’ll call it me testing their security systems.”

Tom Alley sauntered into the sitting room, making a beeline for the armchair and collapsing into it, sinking down and spreading his legs suggestively. I followed after him, going for the settee opposite and snatching one of the overstuffed cushions to cover myself as I did. “And how exactly did you find me?”

Tom tapped his nose. “Just followed the smell. Your scent has practically permeated the whole building so it smells like a frat house after a two day long orgy. I half expected to find cum oozing out the walls like a horror film or something. Instead I just find you coating a bathroom. No disrespect, that’s still quite the feat I’ll grant you.”

“Yeah…well…” I floundered, not really knowing what to say but wanting to say something. “Most of it was eaten. Drank…eaten? Whatever!”

Tom chuckled again, grinning to show off some pearly whites with distinctively sharp canines. “Oh, let me guess; you had your own personal condom by the name of Expando? He must have loved that, what with that story of his dad and the radioactive Johnny he’s always telling.”

“I didn’t use… wait, radioactive condom?!”

“That’s the way he tells it. His dad found a condom while he was working at a nuclear reactor, used it on Expando’s mum and next thing you know she’s pregnant with a rubber baby.” Tom snorted loudly. “I’m about 90% sure he’s lying, since his skin can’t actually be cut so how could the condom have torn enough to have failed on conception anyway to then give him rubberised powers? You’re looking at me like I’m crazy. In my defence, I have had a lot of time to think about this, probably more than I should have. It’s his story though, I’m just repeating and disbelieving”

Once I realised my mouth was open, I closed it. That wasn’t how I’d heard about Expando’s origin story went. Then again; I could see why perhaps he wouldn’t want that to get out as well. Radioactive condom…

Tom snapped his fingers, bringing me back. “Anyway, we’re supposed to be talking about you. You’ve got some high-powered pheromones you’re kicking off and they are practically screaming for anyone within smelling distance to suck your dick. It’s not as strong as it was, so I assume since you’ve gotten off it might have…alleviated the pressure if you will.” With a creak from his suit, Tom sat up, going from lounging sex in a suit to a more attentive teacher. “First thing’s first; I want you to hold your breath for me.”

“Hold…hold my breath?”

“No need to repeat, just do. Take a breath, fill those titties of yours and hold it.”

Twisting my lips I covered my bare pecs, maybe a bit embarrassed now they’d been pointed out like that. Had seemed like a good idea to try and fill out a bit so I didn’t feel like a plank of wood next to everyone else in the building. Tom just smirked at me, waiting.

As instructed, I took a deep breath, my stomach going in and my chest going up. Once my lungs were full Tom held up a finger. I looked from him to it, waiting for him to drop it to signal I could let my breath out. I waited. And waited. The seconds ticked by, crawling into a minute and still he kept his finger up, wanting me to keep it held. I was starting to feel the strain. Probably someone who had worked to gain the body I’d given myself might have had an easier time, having had better endurance from exercising and the like. Since all I’d done was willed it and sucked cock, I didn’t seem to have any of the stamina the body should have given me. Or bigger pecs didn’t necessarily mean larger lung capacity.

I deflated as I let the air out and took a hungry gasp of breath back in. Glaring at Tom I panted “Are you…trying to… kill me?”

Unperturbed Tom waited until I had my breath back before speaking. “I was asking you to hold your breath, I wasn’t doing anything to stop you from letting it go. Hardly a risk of death. Now, let’s try again.”

“What for?”

“Training purposes.”

Tom made me hold my breath again and again, all the time holding the bloody finger up and never letting it drop before I had to give up. Every time I got angry enough to say I was going to do it this time, that I was going to outlast him. Every time I was proved wrong. After what felt like several tries, just as I was starting to get a bit dizzy, Tom gestured for me to relax while he settled back in his chair as well.

“Not a bad start.”

“What exactly was that in aid of? What has holding my breath got to do with holding my pheromones in? Surely it’s other people who would need to hold their breath to stop it affecting them.”

“It might help them a little—not in the long run, though, as you’ve shown.”

“So what was that for, then?!”

“Calm down. It was an exercise on control and containment. Like holding your breath, I’m trying to show you how to hold your more alluring pheromones in. I just wanted to get you used to that sensation, that bodily control of something that your body does naturally. You’re not gong to be able to do it indefinitely; you can’t keep focus on it all the time and it doesn’t take much of a slip to lose your hold on them. It will at least let you be in a room with the others without them doing this!”

Tom gave me such an intense look I felt my breath leave my body and my head float a way as well. In seconds I was covering the distance between us, the cushion falling off my lap forgotten as I straddled his waist, cupped his face in my hands to kiss him. His stubble was rough on my hands but his lips were so warm and soft. His hands grabbed my backside, kneading at my new firm glutes like dough, pulling me closer so my cock rubbed against his core. He also started grinding his own crotch against my taint, growling a chuckle against my lips before my tongue found its way into his mouth.

I broke the kiss, panting before diving back down, kissing my way down his throat, feeling his prominent Adam’s Apple bob as he swallowed. My lips trailed down his collar, dancing over his chest peeking out of his suit. I shuffled back off the chair, going to the floor so I could better burry my face in his hair chest, unzipping his suit to get more of it. I shoved one hand in, grabbing at his meaty chest and giving it a squeeze. A small part of my brain, somewhere far at the back said that Jacob’s were far better, much bigger and grope able, it didn’t stop me squeezing harder nor stop my enjoyment. My mouth moved lower, kissing every hairy ab as I went lower and lower. His zip went straight down, rising over the bump of his cock which was now pulsing visibly hard, stretched out to one side. The zip came all the way down and out his cock and balls fell.

“Easy now,” crooned Tom, hands running through my hair, holding the back of my head. “Didn’t think you’d start smelling so good once I had you going. Let’s settle down some shall we?”

“I want your cock so bad,” I moaned, taking it in my hands and squeezing it. Tom’s abs tensed as he gave a sharp intake of breath. “I can make it bigger if you want, make it fill my hands.”

This time Tom’s chuckle was darker, more wicked. “Never had someone under the influence say that to me before. Normally I’m perfect.”

“You are…but…bigger is…better.”

“Size queen. Come on now, up you get.”

Reluctantly I released Tom’s cock and stood up. My cock was rock hard, and with a throb it swelled a bit bigger. Tom’s dark brows rose a fraction at the sight of it, his hand twitching as though wanting to reach out for it and stopping himself at the last second.

“Potent stuff,” he said, physically showing signs of resistance even though his eyes couldn’t leave my cock. “See if you can reign that in…” Tom’s tongue wet his lips and he swallowed.

It was hard, not just my cock, trying to fight the urge to carry on. I wanted nothing more than to see my cum dripping from Tom’s mouth, his suit filled to his limits as he swelled and grew into a muscle blimp. A little pay back for the breathing exercises, to test his limits, to see how much he could take, how much I could fill him…

I held my breath. I focused on holding my core, of holding myself in. Unlike holding my breath, this felt like what I was trying to hold in was actually fighting against me. It didn’t want to be contained, it wanted to be free, it wanted to make things bigger!

“Good for a first attempt.”

I blinked. Tom was no longer on the chair before me. I spun. Somehow he’d managed to slip past me and was standing on the other side of the room, his suit back up to his chest again. His hard on was still obviously throbbing though.

He gestured for me to sit down, waiting until I sank into the cushions before he came closer. “You had a fairly decent hold on it there, a few more tries and you should be fine. Maybe getting you worked up first might not have been the best idea.”

“Am I still sending out ‘suck my dick vibes’?”

“Yes, they did stop for a bit, only while you were concentrating. Came back quite strong afterwards though. We can work on that more though. Try it again now.”

For the next few hours, Tom had me practice and practice and practice controlling my pheromones. He helped show me how to keep them contained so at least if I was in a room with the Wardens again, things wouldn’t get too out of hand. He also showed me how to use my pheromones to my advantage, to potentially gain a little influence over others. My goal became to try and compel Tom to tell me a secret about himself.

“You’re definitely improving,” he said, after taking a few steps back. “There was a bit more compulsion to that last one, although I still wanted to suck your dick rather than tell you anything.”

“So if I let you suck my dick you’d tell me maybe?” I asked, trying to sound like I was joking whilst skipping in a little subtle manipulation.

Tom just chuckled, adjusting his stiff cock. “Better, that was a better attempt. Bearing in mind I’m a little more adapt at fighting these kinds of things, you’ll find it easier on others I’m sure. You’ll get the likes of Expando on his knees no problem.”

“That won’t be through any sort of mind manipulation though,” said a familiar voice.

“Knew you’d take the bait.”

Expando bounded into the room, his mask off and his hair all mussed. He ran a hair though it, trying to get a bit of volume back to his loose curls. He shot me an appreciative smile, eying my new body up and down and clearly liking what he was seeing. “You been teaching Super Dick here some bad habits I bet,” he quipped, still checking me out.

“Nothing worse than what you’ve been getting up to, from what I hear. I’m at least the same size I was when I walked in.”

“Losing your touch there, you alley cat. Can’t even entice this horn dog to want you.”

“Everybody wants me,” Tom purred, and I sensed him start kicking out his own pheromones. Having felt him work his influence on me a few times over the last few hours I’d learned how to feel when he was doing it.

Expando closed his eyes veered closer towards me. “Nope, nope you’re not gonna make me fall for that. Quick, protect me Steve!”

I laughed as Expando wrapped his arms around me, literally, and held himself close. His rubbery arms encircled me, trapping my arms at my sides while he buried his face in my neck. I became very aware of how naked I still was and quickly put a dampener on my pheromones. From the way Expando was grinding his crotch against my leg though, it didn’t make much of a difference on him.

“Not gonna leave me out, are you?” asked Tom, pouting a little.

A shiver went through me as I started getting swept up in his allure as well. Expando’s arms tightened around me for a beat, then relaxed and began to unfurl. He plodded over to Tom and started kissing him, the hero in black smirking and giving Expando’s rump an affectionate spank.

“Damn it,” Expando grumbled, stretching his neck back and away even though his body stayed close and personal with Tom.

“Where are the others?” I asked, trying really hard not to go over and join them while at the same time keeping my dick from getting any bigger. The last part was the hardest, any feeling of arousal was like a trigger for my growth powers to start swelling my junk with size. Even with me concentrating I felt my balls quiver and inflate a little.

“They’re following a lead,” said Expando, still enraptured by Tom. “We found one of the Body Builder’s suppliers and Watcher thinks we’ve found a potential base for him. We’re moving now so he doesn’t have the chance to slip away again. I’m supposed to be meeting them there but wanted to swing by to see…” Expando managed to pry his intent gaze off of Tom to look at me, “…you. Make sure you were all right.”

“Does that mean you found Dr Garner?”

Expando hesitated for a second before nodding. “Yeah, we’re pretty sure he’s there too. Don’t worry, we’ll get him back.”

“I want to go with you.”

“What?” said Tom and Expando together.

“I want to go with you,” I repeated. “I want to help.”

“But… it’s dangerous,” said Expando. “Steve, I know I call you Super Dick but…but you’re not a hero. You’ve not had any training and your powers aren’t…they’re not exactly built for combat. What are you gonna do; whip your dick out, crack one off and hope that your target swallows enough to get too big to move?”

“Well…”

“Not to mention it takes a few seconds for your cum to actually make someone grow. You’d be overwhelmed before they’d even get a little tingly. No, it’s too dangerous.”

That responsible, serious tone sounded almost strange coming from the bouncy, impulsive Expando I’d come to know. I guess even with all his joking around he was, at his core, a good guy, a superhero after all, not just a horn ball, and he did take that role seriously. Tom silently watched our exchange, no longer funnelling pheromones into the air purposely which might explain Expando’s return to reason.

Maybe I could test the resolve.

I relaxed my hold, my shoulders dropping in what I hoped would appear as an outward sign of acceptance. I let my will slough off of me and focused it on Expando. Tom instantly knew what I was doing and narrowed his eyes. He didn’t say anything though.

“Could you tell me where you’re going, at least?”

There was only a brief pause, Expando blinked, and then he gave me the address. I brought myself back under control, sending out one final pulse before closing it off completely. “You’d probably better go catch up with them. Don’t want to keep them waiting.”

Looking a bit dazed, Expando nodded. “You’re right. I just wanted to check on you first and let you know what was happening. Can’t hang about though.” He began to brighten up, becoming more like his usual self. “We’ll be back before you know it. Then we can have some fun,” he wiggled his eyebrows and winked at me.

Once he’d gone, Tom looked me up and down, a wary caution now in his gaze. “You do pick things up quick.”

I shrugged. “You said Expando was easy to compel.”

“Hmm,” Tom mused, his face becoming unreadable. “You’re going to the base.” It wasn’t a question, so I didn’t answer. “Well, I can’t let you go alone, as competent as you appear to be. You do realise you could be more of a hindrance than an asset, though?”

“I’m tired of standing around. I need to do something, and if I can help Dr Garner then all the better. And maybe…maybe I can get more information on why the Body Builder’s formula did…this to me.”

Tom let out a long sigh. “Fine, I tried to dissuade you. Before we go, though… do you have any clothes? You’ve not made one move to get dressed since I came in.”

My heart was racing. What had I been thinking?!? I spend a few days surrounded by superheroes and now I thought I was one? I should have stayed in their base where it was safe. Instead I was clutching a coffee in trembling hands in a café across from the building I was going to be breaking into. My ‘partner’ was out of sight, doing a discrete check while I was supposed to be observing the main entrance. I was too flustered though to pay attention, constantly checking my watch so I wasn’t late for the rendezvous.

It also didn’t help that the clothes I was wearing felt so tight. Tom Alley had probably done it on purpose when he’d picked them out for me, finding the thinnest, tightest T-shirt he could and a pair of skinny jeans that no guy with quads my size should even attempt to wear. There had been a lot of jumping about and grunting when I’d pulled them on, and now I felt tingles in my feet from poor circulation. I was going to have to be cut out of them. I felt conscious of everybody looking at me, especially the way my nipples poked out whenever I felt a breeze brush past them.

I left the café five minutes early because I felt so self-conscious, marching out into the encroaching dusk and into the alley Tom had instructed me to meet him at. I moved into a doorway to hide from sight and waited.

“Get a little impatient?”

I failed to hide my surprise at Tom’s arrival. I knew he would drop in quietly and had been waiting for him to scare the shit out of me. My nerves were too frayed though to completely hide my surprise.

“What did you find out?” I hissed.

Brows puckering at my hushed voice, Tom spoke normally. “Child’s play really, found about 16 ways I could get in and out with no problem.”

“That’s good then, plenty for us to choose from .”

“I said any I could get into. Not so many for you. I did find the Wardens, though, they’re bickering over on the opposite side. My guess is they’ll use Density to phase in and open a door for the rest, they’re just not sure where it would be best to enter.”

“Shit,” I breathed. I’d been so focused on getting in I hadn’t even thought about the real heroes also mounting a rescue mission. What was I doing?! I should just leave things to them, I was in over my head.

“Settle down, you’re starting to grow.”

I looked down in time to see my pecs visibly pushing outwards. They stopped once I noticed though, my shirt now stretched to its very limits. One deep breath or bend and something was going to pop. I didn’t bother trying to shrink down, the front of my jeans couldn’t have taken the trade-off.

“Good boy. Now, I think the best way we can get you in is by a little side entrance on the South side. There’s one guard in a little booth, hardly has any foot traffic, so you can just go in there, put on a bit of charm and get inside.”

“Wh-what should I say?”

“Just let your body do the talking.” Tom winked. “I’ll be right behind you, so don’t panic.”

Easier said than done.

The walk out of the alley and towards the entrance felt both far too long and instantaneous. The dread at what I was doing making me switch from wanting to getting it over with now and begging for more time to prepare. I tried to go over what I was going to say in my head, only ever getting as far as ‘hello’ before my brain just short circuited and I began to panic. I think I gained a few more pounds on the way, a cold breeze brushing my inner thigh as a seam gave up.

Unable to hear anything but the thudding of my heart and the blood it sent pounding through my ears, I approached the door, waving to the guard through the little window. I hoped my smile wasn’t as tight and manic as it felt.

The guard frowned at me for a second, then pressed something on his desk. There was a buzz, the lock disengaged, I opened the door and stepped inside.

I entered into a corridor, the guard watching me from his booth divided from me by a window with a hole at the base for things to be passed through. Opposite was a set of double doors, normal looking though to my mind’s eye they could have been a 5 foot thick titanium slab with bars and chains keeping it in place. I jumped when the door behind me closed and the lock slid in with a very final thunk.

Swallowing, I approached the guard. He was skinny, skinnier than I had been even, with a dark goatee with a few streaks of grey under his lip, bushy brows furrowed as he looked me over. His frown seemed to deepen when he came into my nipples.

“You’re early,” he grunted. “Interview isn’t for another half hour.”

Interview?

“Sorry,” I said, trying to think what to say. “Traffic was better than I expected. Am I all right to… wait inside?”

I knew I’d said the wrong thing the way his eyes hardened. “Son, I can’t just let you walk in to a secure facility like this. You’re gonna have to wait until Mr Chambers comes and gets you. Did you not read the instructions before coming down here?”

“Sorry,” I chuckled nervously. “Just… flustered is all.” My obvious nerves helped show that part at least was true.

The guard grunted and shook his head. “Hiring meatheads,” he mumbled, then said, “I suggest you go over your application again and come back at the proper time.”

“Yeah,” I hedged, trying to think of something. I didn’t want to leave, but didn’t know how to get him to let me in. Unless… “Do you mind if I stay here?”

The guard sighed heavily. “Son…”

“I’ll make it worth your while.” Come on pheromones, do your thing already! My jeans were starting to feel tight around my crotch, my dick stirring to life. I unbuttoned my jeans with a barely contained sigh of relief.

“Just what the hell to you think… you’re… doing?” A pause. A breath. “You’re… you’ve got quite the piece of equipment there.”

I smiled, rolling my tight shirt up my abs. I tugged the front of my jeans open, the zipper sliding down, revealing the ample bulge in my underwear. “Yeah, it’s so hard keeping it contained. Need to let it out every now and then. Is that okay?”

The guard swallowed and nodded, transfixed.

“He’s a grower too,” I said nanchalantly.

“Fuck… really?”

“Yeah.”

“No… not it can’t be real… is it?”

“Have a feel?”

Hesitantly at first, the guard put a hand through the slot, fingers brushing the head of my shaft, gentle enough to make me shiver. He squeezed it, daintily with his fingers, moving down the shaft to see how far it went. I’d intended to make it grow for him, his touch felt so good I lost control for a second and it thickened more than I’d intended.

“Fuuuuck,” he gaped, recoiling in shock at the surge in size my dick swelled. “Unreal.”

“So tight,” I winced, my balls still trapped in my skinny jeans. With a shove I managed to shift them and my underwear down a few inches, gasping in relief as my balls tumbled. As though sensing the extra space they shuddered and ballooned that bit bigger before I could get them to stop. “Oh shit, oh shit. I need to…I need to…”

“I need it,” the guard moaned, reaching through the gap to grab my cock. He pulled and I shuffled forward, bumping against the edge of his desk, his hands groping as much of my cock as his could. The slot in the window became a glory hole as he started stroking it, squeezing it, and then lowering his mouth to take my head.

“Oh shit,” I panted, my plan getting away from me. I’d only wanted to work him up to get him to do what I wanted, now I’d lost control. I tried to reign it back in, but my dick felt so good in his mouth I didn’t want to stop.

Maybe I could still make this work.

I let my dick grow, taking off some of my muscles slowly and channeling it to my dick, making it longer. The guard gagged a bit, my head poking the back of his throat and forcing him to step back too. His eyes goggled at my cock, his pawing and attention never slacking though. His lips left my cock with a wet pop, letting him take a breath enough to say “What a cock,” before diving back on it.

Next, I focused on my balls. If my plan was going to work, I’d need to give him a lot of cum. With an almost audible sound of sloshing and stretching, my balls swelled bigger and bigger, ballooning to oranges, then to cantaloupes, and still I made them bigger.

“Need more,” I panted, “need to make more. Fuck, it’s getting too big.”

My concentration was slipping again and my dick joined in on the growth, getting thicker and thicker. When I felt the edges of the gap digging in I managed to stop myself. By then my cock was huge! The guard couldn’t fit the head in his mouth any more, he could only just suckle on the very tip, tongue probing the slit while his hands slid up and down my glands. Fuck there was so much pre trickling onto him and over his hands, making him slip and slide so sensationally.

I couldn’t hold it back any more.

I had to bite the heel of my hand to keep from crying out. The first volley came out like from a cannon. The guard’s cheeks bulged with the sheer volume and I wouldn’t have been surprised if the excess squirted out of his ears. He gripped my cock tight though, holding on as he swallowed as much of it down as he could. The next shot came, and the next, and I could visibly see his skinny frame bloating out with my load. His belly pushed out against his shirt, lifting it out of his trousers, pulling the buttons taunt.

As my cock shuddered with the last shot I felt it start to shrink back down, the guard falling back into his chair, arms falling to his sides as he gasped for air. Ropes of cum still connected his lips and some dribbled out of his chin. He quickly started collecting it all though, licking it up and then using his hands to scoop up whatever he could. He then sat there, still panting, rubbing his big cum belly that rested on his skinny thighs using those twig like arms.

“Fuck!” I panted, gingerly putting my cock away, shuddering at its sensitivity so soon after blowing. “You were really good at that!”

“Never done that before,” he gasped, covering his mouth when he hiccoughed. “Never knew cum could taste so good.” His eyes landed on his bloated gut. “Fuck me, I’m so stuffed.”

“Do you think you could let me in now?” I asked, conscious of my time slipping away.

“Huh?” the guard grunted, still caressing the curve of his tight stomach.

“Can you open the doors to let me in?”

“Oh…sure.”

He moved forward, grunting when his gut caught his desk. He giggled. He ended up having to swivel his chair to come at it sideways, finding the butting he needed and then the door buzzed.

“Thanks,” I said, hurrying to the door and opening it before the buzzing stopped.

“No problem, that was such a… hey… what’s… what’s happening?”

With a low gurgle, the guard’s stomach began to recede. He watched wide eyed, hands feeling it as his belly deflated and he shrank back to his usual skinny frame, shirt hanging loosely on his lap after being stretched.

“Oh… I kinda liked that.”

“Just wait for it,” I said, knowing I should be moving on but wanting to see the next part even more.

The guard started to rise, then stopped. He sank back down, pushing back into the chair as he let out a low moan. I could see the front of his trousers visibly swell, his bulge rising up beneath his shirt. His mouth dropped, gaping at his crotch as it grew and grew, straining against his groin. That was when he noticed his whittled legs begin to pulse and thicken. Muscles began to tense and flex beneath the material, the various heads writhing and mashing together as they fought for space. He spread his legs as muscle, cock and balls began expanding outwards.

His mouth was knocked closed as his chest suddenly surged, pecs pumping out like airbags. His name tag fell off, clattering on the floor as his pecs stretched his shirt to its limit. Thick, powerfully arms swelled out either side, the sleeves digging in tighter the bigger they got, the guard marvelling at them, lifting them and tentatively flexing his rising biceps. He wasn’t even fully flexing, just bending his arms was enough to make the ball of muscle pump up bigger, and thicker. When he actually took a second to properly flex, his sleeve shredded and the flesh began to peek though.

“I’m so big,” he gasped, “I’m getting so big!”

He pushed himself out of his chair, grabbing his shirt and tearing it off, his chest heaving out in the open and revealing the tight, chiseled core that sheltered beneath them. He tugged and pulled at the last of the threads and then grabbed the waistband of his trousers. His triceps ballooned thickly as he heaved and the material came away like wet tissue paper, his briefs visibly bouncing with the full basket still packed tightly inside. The remains on his thighs and calves split and fell away, remains clinging around his knees and ankles even as his shoes burst as his feet broke free.

“Fuck me, I’m so fucking big! I’m huge!!” the guard cried out gleefully, flexing and groping himself. “And I’m still growing too! How is this…wait…wait how do I stop it?”

His groping was losing some of its fever as he was finding his movements getting restricted. All the muscles that were piling up on his body were starting to get in the way of each other. His arms were getting so thick he could hardly bend them, his pecs pushing up against his chin while his traps rose up against his ears. He staggered and struggled to move his legs as they just got heavier and heavier.

“Wait stop, stop, please I’m getting… I’m getting too big!”

His briefs snapped off and his cock flopped out, surging forward in a rapid burst of growth. It slammed onto his desk, knocking his computer and everything else to either scatter on the floor or be crushed. He was rapidly filling his increasingly cramped booth, pecs pressing against the window, cock draped over the desk and snaking to one side. I couldn’t see how big his balls were at this point, just most of his torso and his dick bulging out above his desk. His arms were out at his sides, almost in a T pose, nothing but muscle bulging in every which way, his hands unable to more than flap and flail.

“Help, help it’s too much!”

His words were becoming muffled as I lost sight of his head, getting swallowed by his pecs and traps. How much had I given him? I was sure I’d given the heroes more than that back at their base. Had I lost that much concentration when I’d been making my balls grow and overdone it? Or…or was my cum more potent now?

A large crack appeared in the glass and I took a step back. Shit, what had I done?

Holding my breath I waited a few extra seconds, waiting to see if the window would hold. With a sigh of relief I realised he’d stopped growing, his muscles only rippling with his breathing and his frantic attempts to move. He was calling for help, muffled by his bulk so no one was likely to overhear him.

I hadn’t quite planned him to get that big. I’d only wanted to immobilise him for a bit so I could get in without alerting anyone. Looking up I saw a security camera blinking at me accusingly.

Well, shit.
