Kev, did you see a glass here?”
“Whoa, man, was that yours? Sorry… I was really thirsty…”
“You drank it!?”
“Sorry, bro. Honest mistake. I'll make it up to ya.”
“Kev, you don't understand…”
Suddenly, Kevin swooned, “Whoaaa….what's going on? I feel weird…”
He was seized by a paroxysm of pain, shreiking, “My God, what was in that stuff?”
He staggered a few steps, clutching his stomach, gasping, crying…
Blinking back tears of disbelief, I sputtered, “Kev…”
As if someone struck him from behind, his back arched upward, arms flying out to the sides. Strangely, his feet remained rooted in place, as if glued to the floor. In this position, his body went rigid. Caught in the middle of motion; stiff and immobile. A tremor made its way up his legs. His eyes rolled back. He drooled pathetically. Finally, he fell on the floor, his body stiff and trembling violently. I tried turning him over in an attempt to get him up, but couldn't budge him.
Perspiration poured down his flushed cheeks. His eyes bulged sickeningly.
There was a shift in the timbre of his whimpers. His crying took on a deeper resonance. There was nothing I could do…
Kevin was changing…
I felt his body begin to swell beneath my hand. His loose plaid shirt started stretching tightly across his broadening back, pulling the pattern into a taut checkerboard.
His muscles grew underneath the shirt. Huge, inhuman muscles. Muscles that people like me would kill for. Big, rounded delts filled Kevin's sleeves. I saw them bulging rounder. Wider. Wilder. Deepening shadows betrayed the onset of powerful traps bulking up under Kevin's shirt; his back grew outward, widening, taking on that inevitable V-taper. I felt muscular knots erupting all over his back, imagining the sensation of the incredible power that was overtaking my baby brother.
His high-pitched whimpers had become animalistic grunts. He was no longer a boy. He was a man. Barely that. A monster.
In seconds, Kevin's shirt had swelled to bursting with his growing torso, his shoulders, the size of cannonballs, poised to rip it clean off his back. I made out the fierce horeshoe-shape of bulging triceps pressing into the clinging sleeves; his freaky traps peeking out of his collar. His tight jeans choked and chafed his outrageous legs; the development was so complete, even his hamstring veins were clearly delineated beneath the dense fabric.
Kevin's face was beet-red; his eyes clenched in rage; he snarled and spat savagely. He wanted out. He was now far too big for these pesky clothes. A sixteen year-old muscle giant with an attiitude.
With a sharp crack, Kevin's immense back split the shirt wide open, exposing a fantastic set of dense, rippling rhomboids. After a resounding grunt of relief, he groaned lustily as his hulking lats breathed in the fresh air, overtaking the pathetic clothing imprisoning his hulking body. His swelling delts neatly tore the sleeves free. He clutched at his chest, violently ripping open the shirtfront, allowing his massively surging pecs room to grow. The muscular landscape of his back expanded further, muscles popping and swelling everywhere; the hole in the shirt widened, crawling up to the yoke, finally splitting the collar. Mind-boggling traps obscenely bulged into view as the whole bodice fell helplessly to the floor, exposing his staggering lat-spread. I could see hints of his bulging pecs peeking out beyond his terrific wingspan. From the back, Kevin looked like two linebackers squashed into one; his neck as succulently thick as most men's legs; his traps big as melons. The rest was all lats, except for the slender waist that, seemingly defying gravity, upheld his mighty torso.
Kevin's outrageously developing delts and triceps ultimately destroyed the sleeves, first peeling back the engorged fabric, then alternately blasting and splintering it till the rags fluttered wistfully around him. Thick, pulsing veins revealed themselves below the skin-surface, encircling his gigantic biceps and forearms like deadly snakes. His biceps, the definitive symbol of manhood, bulged and pulsed with monstrous size and strength.
There was another terrific cracking sound; the seat of his pants split, pouring forth great globular glutes, splitting down the length of his jeans with a delectable, prolonged rrrrrrip. Kevin's tremendous hams and calves bulged themselves into glory, massive and developed beyond belief; wide as great oaks, solid as granite. Kevin looked about savagely, trying to catch a glimpse of the obscene growth enveloping his once scrawny body, transforming him into a living, breathing, bulging hulk. Thick, curly, black hair sprouted on his chest and legs, coating him in a blanket of luxurious, sexy, masculine fur.
He was naked from head to toe. His skin glowed pink. His phenomenal body was clenched in fury, every muscle flexed to bursting, veins pulsing his superhuman blood in a frantic attempt to keep up with his accelerated strength.
He turned to face me…
I almost passed out at the sight of his huge heaving pecs topping his massive torso; the tremendous shoulder development, his succulently freaky biceps, the serrated abs. His almost frighteningly developed quads, and a dick that would make even the most jaded sex goddess beg for more.
He eyed me furiously, hitting a terrifying most muscular. We knew who is boss now. You just don't fuck around with 275-pound sixteen year-olds.
He started to walk over to me when another massive spasm hit. He again locked into a stiff form with his feet glued to the floor. His muscles began swelling again getting even bigger and stronger. He chest hair darkened and got thicker while his dick grew thicker and longer. The process ended as abruptly as it began except this time my baby brother was beyond huge he was impossibly big. Before the second transformation he was at least human, but now he was way beyond human. Even the most massive bodybuilder known to man was like a prepubescent boy compared with him. He was truly amazing.
After seeing Kevin like this my cock was throbbing in my pants. The largest and most powerful man on the planet was standing in front of me and he happened to be my 16 year old baby brother. I almost fainted when he flexed his huge bicep and rubbed his hand over it.
He walked over to me and stopped when his chest came within 6 inches of my face. I was staring at the most magnificent chest in the world. It look as wide a three pro linebackers put together and was covered in thick black hair. I slowly looked up into my little brothers eyes and saw anger. I knew that this could be the end of my life. Kevin reached down and grabbed the front of my shirt and with seemingly no effort hefted my body off the ground until we were eye to eye. I decided to let him make the first move.
“What have you done? Look at me! I'm a fucking freak!” He said in a loud deep and booming voice. You could probably hear him for miles. The anger in his eyes seemed to grow and I knew then that I was dead, so I reached out and touched his massive chest. If I was going to die, I at least am going to touch the chest of the biggest man in the world and die happy.
Then a strange thing happened. Kevin started laughing. He must have noticed the puzzled look on my face because he said, “Had you going didn't I?”
“What? Your not actually mad?” I was still confused.
“Not at all. How could I be. You gave me this magnificent body. I've been after this type of body all my life. Wishing for it and you gave it to me. You want to know a secret.” I nodded weakly. “I've been using the weight set in your room twice a week since you went to college.”
Still concerned for my life I said, “That's okay. I don't mind.”
“Don't worry, Mike. I'm not mad. Promise. I've always wanted to be like this. It's great.”
I finally started to feel like I wasn't going to die. “I'm glad I could help, even though that formula was intended for me.” Quickly changing the subject so I wouldn't get him mad, “So, what type of results did you get with the weights?”
“Nothing like this. But I was improving. I was up to 160 on the bench.”
We talked about working out for about 10 more minutes when I finally asked, “Say, little brother, could I ask a favor?”
“Would you mind putting me down. Being held over 2 and a half feet off the floor isn't very comfortable.” Even though I was quite comfortable. I was actually enjoying being held up by my little brother, but I was worried about his arm it must be getting tired from holding up my body.
“Sorry, bro. I forgot I was holding you up.” After he put me down he said, “You know, it was like you weren't even there. My arm didn't seem to even notice your weight. How much do you weigh, any way?”
“193 lbs. Fuck Kev, you must be the strongest man alive. You were holding me over 2 feet off the ground for over 15 minutes with only one arm and didn't even notice the weight?” I was shocked. He couldn't be that strong, could he? My cock got rock hard just thinking about it.
“Nope, your as lite as a feather. I gotta try something.” With that he ran down the hall towards my old room. I could feel each of his steps through the concrete and wondered how much he actually weighed now. Amazing, I thought again. Didn't even notice my weight and only one arm. Shaking off the shock, I followed my brother down the hall.
When I got to the room he had loaded up the bar with a tremendous amount of weight. “Kev, that's about 500lbs. You sure you can handle that?” I had a heavy duty set of free weights in my room and he was making full use of it.
“Won't know 'til I try.” He slid under the bar and in one smooth motion he raised the bar of the bench. Then he lowered the bar to his chest and pushed it back up again. It looked like it took no effort at all and he continued. After 50 nonstop reps he put the bar back on the bench and sat up. He wasn't even breathing h ard.
“Nope. It's to easy. I can barely feel the weight. It's the same as when I was holding you up. Didn't really feel a thing. I just need to put on more weight.”
“Kev, you've about used all the free weights that I have here. You could add maybe a couple hundred more pounds and that would be it.”
“Well then, well just have to try that.” He added all the extra weight I had left in the room, exactly 200lbs, and got under the bar. He raised it again. Still keeping perfect form he counted out 100 continuous reps and stopped. “Still not enough. Mike come over here and push down on the bar.” I did as he asked and he got under the bar again, as I pushed down on it. I felt my body raise off the ground again as he pushed the bar up. He stopped after 10 reps.
“What's wrong? Tired?” I asked again, hoping he wasn't.
“Nope, Just didn't want to over stress your arms. Why don't you try to sit on the bar?”
“If you say so.” I got on the bar and he told me to hold on. I nodded agreement and watched my body get higher as he lifted the bar off the bench. I looked down at his face and chest. He didn't look the least bit strained. Amazing. My BIG little brother is benching 890lbs and doesn't seem to notice. He kept going for 500 reps! I was starting to get sick from going up and down so much that I had to ask him to stop.
“Sorry, bro.” Kevin said, “Didn't realize you were getting sick. I planned on doing another 500 reps.”
“What?” I looked at him in utter disbelief. “1000 nonstop reps. That's incredible. Don't you feel the least bit tired or sore?”
“Nope. That little workout didn't even phase me. Look. I'm not even sweating, hell, I'm not even breathing hard.” Again, my cock went full mast and my brother noticed and smiled. “You like that, bro.” He nodded toward my bulge.
I nodded back weakly and said, “Yes.” I looked up in his eyes to see if he was mad, but what I saw shocked me. He was still smiling.
He put his massive hand on my shoulder which happened to be wider then my shoulder but that didn't matter. He said, “You want to know another secret, I wanted you since I first saw you in the naked in the shower.”
I looked up at him shocked. “I never knew you were gay.”
“All this time, I've bee trying to be like you, Mike. You're my idol. I love you big brother.”
“I love you too, big little brother.” We both smiled at each other. “What do you say we go into the big bedroom?”
“Okay, little big brother.” Kevin said chuckling. He must really like being a hell of a lot bigger and stronger then his 20 year old not so big brother. I started to walk out of the room when Kevin grabbed me and lifted me a couple of feet off the ground and headed for the hall. When he passed by the weight bench he grabbed the 700lb bar and picked it up like a toothpick with his other hand and continued towards the hall with out breaking his stride.
He set both me and the bar down. “Why did you bring that?” I nodded towards the bar.
“I don't know. Sense you like me to show off my strength I thought I'd do just that.” He was already naked, but I still had to take off my clothes. “Oops, forgot one thing.” He left and came back with the belt I use for adding weight to dips and a heavy chain.
“What's that belt and chain for?”
“The belt is for an idea I had, we'll use that latter. The chain I'm going to use now.” He grabbed his massive cock and started to beat it hard. It was an amazing site, Already over 16 inches long and barley hard. After he got hard it was immense. It had to be about 32” long and over 20” around. He looked at me and said, “Watch this”.
He walked over to me and shoved his massive member between my legs and stood up straight. I was easily lifted off the ground by the shear power of my little brother's cock. “Like that?” I nodded happily, unable to speak. “Now watch this.” With me still ridding his cock he walked over to weight bar and wrapped the chain around it and then around his dick. I couldn't believe what he was about to do. He got down on his knees and tightened the chain. Then he bent several links together with his hand to hold the chain at this length. The next thing he did was unbelievable. He stood up and his muscle cock lifted the bar easily off the ground. His cock didn't even bend down. It stayed at the same angle from his body as it did before he put me on it. I was spellbound. He started flexing his cock lifting the 890lbs like it wasn't even there. I grabbed my cock and started pumping as hard as a I could.
It didn't take long before I was ready to blow my load. My BIG little brother noticed and increased the speed of his dick curls. I blew my load all over his massive chest, yet he kept going with the dick curls and I started on my cock again. After he finished 2000 of the curls, I had blown 4 loads onto my brother's chest. He took me and the weights off his prick and started to smile.
“Ready for something else. I haven't even gotten off today.” I wondered what else he had in mind.
