Part 1

Brody had always been small for his age—too small. At eighteen, he stood at just 5 feet tall and weighed only 99 pounds, making him one of the shortest and scrawniest kids in his school. He led a typical teenage life, excelling in most subjects, drawing unwanted attention for his size, hanging out with friends, and playing video games in his spare time.

But this Christmas morning was about to change everything.

As Brody bounded down the stairs, excitement thrummed in his chest. The twinkling lights of the Christmas tree cast a warm glow over the living room where a pile of beautifully wrapped presents awaited. His parents sat nearby, sipping coffee, smiling knowingly as he eagerly tore through gift after gift.

Then, something caught his eye.

A rectangular box sat tucked beneath the tree, wrapped in glossy blue paper with a golden bow—it looked different from the rest. His parents watched as he carefully peeled away the wrapping and lifted the lid.

Inside, nestled between layers of packing, was a set of dumbbells and a large container of protein powder.

Brody blinked in surprise. He had never asked for this.

“Whoa!” he exclaimed, holding up one of the weights. “Thanks, Mom and Dad!”

His parents exchanged a knowing glance before his dad chuckled. “We thought you might enjoy getting into fitness,” he said with a grin. “And maybe putting on a bit of weight, buddy.”

Brody’s fingers tightened around the dumbbell. He had always been the smallest in his class, always the one getting overlooked—and the idea of changing that sent a jolt of excitement through him.

As the day went on, Brody couldn’t wait to try out his new gifts. He started with a few bicep curls, feeling the unfamiliar burn in his arms. Then he ripped open the container of protein powder, mixing it with milk and chugging it down. The thick, sweet shake left an odd but satisfying taste in his mouth.

But his parents had one more surprise in store. His dad handed him a small key, its cool metal pressing into his palm.

Brody frowned, confused. “What’s this for?” he asked, laughing. “Why are you giving me this?”

His mom’s eyes twinkled. “Well,” she said, “we thought you could turn the garage into your own personal gym if you wanted.”

Brody’s jaw dropped.

The family garage had been abandoned for years, collecting nothing but dust, cobwebs, and forgotten boxes. His dad’s old workout equipment had been left to rust, the once-pristine weights now buried under time and neglect.

But now? Now, it was his.

Without hesitation, Brody bolted through the front door, his breath fogging in the crisp winter air. The snow crunched beneath his feet as he reached the garage, fumbling to fit the key into the lock. With a loud creak, the doors swung open.

The sight before him sent a thrill down his spine.

Rusty or not, the barbells, dumbbells, and benches were still there. Treadmills and elliptical machines stood lined against the walls, their displays dark but waiting. The dust didn’t matter. The cobwebs didn’t matter.

This was his space now.

His mind was already racing. This is it. This is where I start.

Over the next few hours, Brody poured himself into the transformation. He spent hours cleaning, rearranging, and setting up his own personal gym. The once-abandoned garage became his sanctuary, filled with the rhythmic clinking of weights and the steady hum of the treadmill.

At first, he took things slowly—basic lifts, short workouts. But soon, he was addicted. His arms burned with every curl, his legs shook after every squat, but he relished the feeling.

His parents watched, stunned by his newfound discipline. The scrawny kid who once spent hours gaming now spent hours lifting.

Days blurred into nights. The garage lights stayed on late. His muscles ached, sweat dripped from his brow, but he didn’t stop convinced it was the key to his transformation from a tiny kid into an athletic jock.

 

Part 2

As the days passed, something started to change.

Brody’s limbs, once thin and wiry, began to fill out. His shoulders broadened ever so slightly, and his arms, while still small, felt denser, firmer. His appetite grew along with him, and his parents quickly noticed. Meals disappeared faster than ever.

“Did you eat all the chicken already?” his mom asked one evening, astonished as she stared at the empty plate.

Brody wiped his mouth with the back of his hand, grinning. “I dunno, Mom,” he said playfully. “Guess I was just hungry.”

His dad chuckled, shaking his head. “Guess we’ll need to stock up on that protein powder sooner than we thought.”

And they did. Just days after Christmas, they were already ordering more.

One night, after a particularly grueling workout, Brody stood in front of the mirror, shirtless, catching his breath. His muscles ached, but it was a good kind of ache—the kind that meant something was happening.

Then he saw it.

His reflection showed the faintest hint of definition in his arms. His triceps weren’t as soft as before. His biceps, though still small, looked just a little fuller.

And then, as he leaned closer—

“Wait…” Brody ran his fingers over his jawline. His smooth baby face was now shadowed with stubble.

His heart leapt.

“Mom! Dad! Come look!” he called, rushing to the door.

His parents entered the garage, curious, and their eyes widened the moment they saw him.

“Look!” Brody flexed, showing off the barely-there definition on his arms. “I think I’ve grown!”

His mom smiled warmly. “You do look bigger, honey.”

His dad gave him an appraising look before stepping closer. “Hold on—let’s check.”

He pulled Brody over to the garage wall where they had measured his height months ago. Brody pressed his back straight against it, his chest swelling with anticipation as his dad carefully marked a new line.

His mom gasped. “Brody…”

His dad stepped back, blinking at the measurement. “You’ve grown two inches. You’re 5’2 now.”

Brody’s jaw dropped.

“I knew it!” he laughed, barely able to contain his excitement.

His parents exchanged amused but proud glances. They had expected the dumbbells to spark a hobby, but they hadn’t imagined it would lead to this.

From that day forward, Brody’s confidence soared. His routine in the garage gym became more intense. His family cheered him on, watching as both his body and his spirit transformed.

At school, though, things were the same as ever.

Brody trudged through the week, juggling classes, workouts, and escaping into video games when he wasn’t lifting. But despite his progress, the teasing didn’t stop.

“Hey, Brody, when are you gonna start hitting the gym for real?” one guy snickered as Brody walked past in the hallway.

“Yeah, you still look like a twig,” another added, smirking.

Brody ignored them. Or at least, he tried to.

But the words stung.

At lunch, he sat alone, scrolling through Simstagram where ripped fitness influencers filled his feed. He compared his own reflection to theirs.

Not even close.

He reminded himself he was making progress. But some days, it was hard to believe it was enough.

That weekend, he snapped.

Brody locked himself in the garage gym and didn’t stop training.

The sound of clanking weights and the steady whir of the treadmill echoed deep into the night. His body screamed for rest, but he pushed through, repeating the same thought in his head—

“I’ll show them. I’ll prove them all wrong.”

By the time Monday rolled around, something else had changed.

Brody stood in front of the mirror, rubbing his jawline again. His stubble was coming in now, spreading across his chin and upper lip.

His first proper facial hair!

“Man, this is getting out of control,” he muttered.

His dad had taught him how to shave before, but he had never actually needed to—until now. Carefully, Brody shaved away the stubble, revealing his baby-faced features once more.

But he didn’t care.

His body was changing.

And he needed to know how much.

That night, Brody approached his dad.

“Dad,” he said, trying to keep his excitement in check, “can you measure me again?”

His dad raised an eyebrow. “Again?”

Brody nodded. “Yeah. I think… I think I grew more.”

His dad sighed playfully. “All right, all right. But if you’re messing with me, I’m making Jaxon go first.”

Jaxon, Brody’s 8-year-old brother, groaned but stood still as their dad marked his height on the wall. Then, with a skeptical look, he turned to Brody.

“All right, your turn.”

Brody stood tall, pressing his back against the wall. His heart pounded in his chest.

His dad marked the new height, then took a step back.

His eyes went wide.

“Wait… no, hold on,” he muttered, double-checking the mark. He measured again.

Then a third time.

Jaxon leaned forward, his mouth falling open. “Whoa…”

Brody felt his pulse quicken. “Dad?”

His dad slowly turned to look at him, his expression unreadable.

“Brody… you’re 5’6.”

Brody’s breath caught in his throat.

His dad shook his head in disbelief. “That’s four inches in less than a week.”

The room went silent.

Then—

No way!” Jaxon blurted, practically bouncing on his feet. “That’s insane!”

Brody let out a breathless laugh, still trying to process what had just happened. Four inches—in just a few days?

His parents exchanged stunned looks. The garage gym, once just a project to help Brody gain confidence, now felt like something else entirely.

Brody turned to the mirror, his mind racing.

The teasing? The doubt? None of it mattered anymore.

Because now, he wasn’t just getting stronger—he was growing.

Overjoyed with the news, Brody hit some poses to show off his growing body to his family.

As Brody returned to school, the teasing continued, but to a lesser degree as many people realised, Brody was now as tall as them.

 

Part 3

The weeks flew by, and Brody continued his relentless routine of eating and working out. The results were undeniable—his frame, once frail and thin, was gradually becoming more robust. Whether it was a late-blooming puberty or some miraculous growth spurt, Brody felt like he had discovered his true calling.

The changes didn’t go unnoticed by his family.

Although they initially attributed it to an atypical late-teen growth spurt, the extent of Brody’s transformation began to raise eyebrows. His family couldn’t help but comment on how gangly the 18-year-old was becoming, but they dismissed it as part of the usual awkwardness that accompanies teenage growth.

While still lean and slender, Brody’s muscles began to show a subtle definition. His upper body gained a touch of muscularity, and his abs peeked through, a testament to his tireless commitment to working out constantly. Additionally, a thin veil of hair had sprouted on his once-smooth legs, another sign of the changes happening.

Determined to track his progress, Brody eagerly awaited Measuring Monday, the day for his weekly measurements. The anticipation was palpable as he and his Dad went through the familiar routine. His Dad, with a twinkle of pride in his eyes, complimented Brody’s developing muscles and jokingly told him to stop tiptoeing.

Brody, however, insisted that he wasn’t tiptoeing.

His Dad’s heart skipped a beat as he measured again, hoping to dispel any illusions.

But the numbers didn’t lie.

Again, his Dad gasped in disbelief. Brody was now 5’8 tall—an astonishing height gain of two more inches. He himself was only 6’1.

The realisation hit Brody’s Dad like a shockwave, and he couldn’t help but admire his son’s remarkable growth.

This was his biggest growth spurt yet!

Brody, on the other hand, was thrilled. The once-petite teenager now close to standing taller than his parents.

That night, after the initial excitement had settled, Brody’s parents found themselves seated in the living room, their expressions reflecting a mixture of concern and curiosity. The rapid changes in their son’s physique were too remarkable to be dismissed as mere puberty, and a lingering worry nestled in the back of their minds.

Brody’s mom, voicing the unease they both felt, said, “Tom, there’s something off about all this. I mean, teenagers grow, but this seems... extraordinary.”

Tom nodded, his brows furrowing with worry. “You’re right, Liz. I can’t shake the feeling that there’s more to it. The speed of his growth, not to mention the physical changes—it’s not normal. Well, not this fast, anyway.”

Liz sighed, glancing at family photos on the wall; they always took family photos at major holidays, Christmas, spring, and Valentine’s Day every year. They were a very close-knit family. She smiled at one of them that captured Brody’s smiling face from a time when he was barely shoulder height to them.

“He’s always been determined, but this is different. I think we should take him to the doctor. Get some tests done.”

Tom agreed, concern deepening. “We need to make sure he’s okay. It’s not just about his growth; it’s about his well-being.”

The decision was made, and the next morning, Brody’s parents sat him down for a serious conversation. They expressed their love and concern, emphasising the importance of ensuring his health and well-being. Brody, though initially reluctant, understood the gravity of the situation and agreed to see a doctor.

 

Part 4

The following days unfolded like a dream.

Brody’s growth didn’t slow down—if anything, it only became more noticeable. Every morning, he would wake up feeling just a little bigger, a little stronger, and his appetite seemed to grow along with him. Whether it was the sheer amount of food he devoured or the relentless toil in his home gym, his body refused to stop changing.

His height climbed steadily—from 5’8 to 5’11 in a week, just shy of the six-foot milestone. His once twig-like limbs had begun to fill out, muscle clinging to his frame, pushing him past the scrawny phase and into something far more powerful. His pecs, once flat, now jutted out slightly, his arms were thicker, and his legs had shed their skinniness altogether.

One of the most surprising transformations, though, was how fast his feet were growing.

Brody’s shoes simply couldn’t keep up. What had once been a Size 7 when he was barely five feet tall had now ballooned to a size 10—in just a matter of days.

His parents were baffled, watching in amazement as their son’s feet outgrew every new pair they bought. Shopping for shoes became a weekly necessity, the bills piling up at an alarming rate.

Still, the strangest part of it all was the awkwardness of adjusting to his rapidly changing body.

Brody found himself clumsier than ever, misjudging door frames, bumping into furniture, and struggling with his balance in ways that frustrated him to no end. The once-familiar world around him no longer fit quite right. His parents had to remind him to watch his head, as he’d already banged it on the kitchen doorway twice in one morning.

“Maybe we should start padding the house,” his dad joked one evening as Brody rubbed yet another newly earned bump on his forehead.

Still, concern lingered.

Brody’s parents couldn’t shake the feeling that their son’s transformation was far beyond normal. At first, they hoped it was just a particularly extreme growth spurt, but as the days passed, it became painfully clear that whatever was happening to Brody was far beyond their control.

They started making calls, researching specialists, trying to find answers—but every medical explanation fell short.

Finally, a doctor’s appointment was set for January 3rd.

As they waited, Brody’s parents watched their son with equal parts awe and anxiety. He was towering over other kids his age, his hands and feet far larger than any of his classmates. Even his facial features were shifting, sharpening into something far beyond his years.

He was starting to look more like a man than a boy.

But while they worried, Brody thrived.

His only focus? Getting even bigger.

Every free moment he had, he was in the garage gym, pushing himself harder than ever. His body ached constantly, but he welcomed it—it was proof that he was growing stronger.

The night before the appointment, Brody went to bed as usual—but his body had other plans.

As he slept, his bones stretched, his muscles expanded, and what should have taken months for a normal teenager happened in mere hours.

The next morning, Brody awoke feeling different.

Heavier.

Still half-asleep, he yawned, rubbing his eyes as he stretched, feeling his sheets sliding off his now larger frame. His body felt dense, almost packed with something new.

As he swung his legs over the bed, his feet thudded onto the floor—a sound slightly louder than yesterday. He paused, frowning slightly, but shrugged it off.

Yawning again, he shuffled to the bathroom, his footsteps echoing just a little louder than before.

Then, without thinking, he stepped onto the bathroom scale.

The numbers flickered on the screen.

142 pounds.

“Huh?” Brody blinked.

His sleepy brain struggled to process it.

He looked down at his feet, his eyes widening at how much larger they looked.

“No way…”

He stepped off, shook his head, and stepped back on, convinced it was a glitch.

142 pounds.

His heart pounded.

“I was… 113 pounds like… a week ago.”

Brody stared at the scale, his pulse racing. “How the hell did I gain almost 30 pounds?”

He ran his hands over his chest, down his arms, feeling the thickness of his muscles, the new weight in his frame.

Then he looked in the mirror.

He wasn’t just taller.

His chest was broader, his arms more defined, his legs thicker, more powerful.

His reflection wasn’t the same skinny guy from a month ago.

No—this was something else.

A slow grin spread across his face.

“This is crazy…” he muttered, flexing his bicep.

A sizable peak rose, larger than it had ever been.

“I’m getting... bigger.”

Later that day, Brody found himself at the clinic for a series of extensive tests. His parents sat anxiously in the waiting room while Brody underwent blood tests, scans, and examinations.

The medical team was thorough, knowing they had to get to the bottom of his rapid and uncontrollable growth. Hours passed, and eventually, the family was called into the doctor’s office.

Dr. Harrison, the lead endocrinologist, shuffled through a thick stack of papers before looking up at Brody and his parents with a somber expression.

“Well, we’ve run several tests on Brody’s pituitary gland and hormone levels, and I’m afraid we have a diagnosis.”

His mother leaned forward, bracing herself.

“What is it, Doctor?” she asked, her voice shaky.

Dr. Harrison took a deep breath.

“Brody has Sotos Syndrome, also known as Gigantism,” he began.

“It’s a rare condition characterised by an overproduction of growth hormone from the pituitary gland. In short, it’s causing rapid and excessive growth, far beyond what we normally see.”

“Gigantism?!” Brody’s eyes lit up, excitement flickering across his face, while his parents exchanged worried glances. His reaction stood in stark contrast to theirs. “So...what does that mean?” Brody asked, the anticipation clear in his voice, leaning forward, almost eager to hear more.

“It means you’re going to get much taller and stronger,” the doctor replied, trying to manage the situation delicately. “But Brody, this isn’t something to be thrilled about. There can be serious health implications.”

Dr. Harrison sighed. “It means that unless we can find a way to intervene or find a way to slow this down, your growth will continue. You’ll keep getting taller, stronger, and larger. Your bones, muscles, organs—everything is growing at an accelerated rate.”

“Can you give us an estimate of how much he’ll grow?” Brody’s parents asked the doctor nervously.

The doctor took a deep breath before responding.

“Well, based on his growth chart and the rate at which he’s been growing, I’d say he could reach a height of around 7 feet...ish. But it’s hard to say for sure, and every child is different. What’s important to focus on is ensuring he stays healthy and monitoring any potential risks that may arise with his growth spurt. We’d like you to come back in a few weeks so we can just keep an eye on it. Medically, it’s complicated. We need to monitor Brody’s condition carefully before deciding on the next steps. we’ve never seen anything quite like this.”

Brody’s mom, tears welling in her eyes, grabbed her husband’s hand tightly.

“But...what happens if it doesn’t stop?”

Dr. Harrison hesitated for a moment, glancing at Brody, who sat there, more fascinated than frightened.

“If left unchecked, Brody will continue to grow, likely far beyond what any of us can predict.”

Brody, nearly beaming at the prospect, asked, “So, I could become a giant, right?”

His mother’s heart sank.

The news from the doctor had sent Brody’s mind into a whirlwind of excitement and anticipation. The doctor’s warning about potential health implications seemed to fall on deaf ears as Brody’s imagination ran wild with thoughts of towering over his classmates and becoming a giant among them.

Despite his parents’ concerns, Brody grinned from ear to ear on the way home, daydreaming in the back of his car about the incredible growth that lay ahead. This was ultimately what he had always wished for: to be taller and bigger than all his classmates.

Once home, Brody wasted no time. The adrenaline from the surprising news fueled an intense workout session that lasted the entire rest of the day. Breaking his old personal best, he devoured a feast, his appetite seemingly insatiable.

 

Part 5

P.5

Brody awoke the next day, rubbed his itchy face, and noticed his facial hair had become even more prominent overnight. Looking down at his developed pecs and abs, he couldn’t deny the visible changes that were occurring to him at a rapid rate. Excitedly getting out of bed, he threw on his fav green t-shirt and sweatpants, only to have his upper body burst through the fabric. “Oh, crap! I guess I did grow,” he chuckled to himself.

Brody’s mom called from downstairs, her voice carrying through the house, “Breakfast is ready, Brody!”

Eager to show off his gains, Brody bounded down the stairs with his usual enthusiasm. But this time—thud!—he banged his head on the ceiling.

“Ow!” Brody exclaimed, rubbing the top of his head, half-shocked and half-laughing at himself. He hadn’t hit the ceiling the day before. “Oh yeah, I’ve really grown! “ he muttered under his breath, grinning.

When he sat down at the breakfast table, the smell of sizzling bacon and eggs had his stomach growling. As Brody dug into his plate, he flexed his arm casually, noticing how his biceps bulged and stretched his T-shirt sleeves. His Dad, Tom, walked in, giving him an impressed but slightly concerned look.

“Wow, Brody, you’re looking so buff!” Tom said, giving his son a light pat on his broad back. He tried to keep his tone supportive, even though Brody’s rapid growth had been a lot to process. Tom wasn’t thrilled about how fast Brody was changing, but he loved his son and wanted to be there for him.

Brody flashed a wide grin, enjoying the praise. “Thanks, Dad! All this working out is paying off,” he said with a wink, proud of how big and strong he was becoming.

Tom chuckled but couldn’t help staring a little longer than usual. Something was different. *A lot* different. “You seem a hell of a lot taller than you did yesterday,” Tom muttered, half to himself, his brow furrowing. It was like every time he blinked, Brody had added more height, more muscle.

Still shovelling bacon into his mouth, Brody looked up at his Dad, eyes sparkling. “Can you measure me again? I know it’s not Measuring Monday, but I feel like I’ve shot up another inch or two overnight.”

Tom shook his head, glancing at the clock. “We’ll have to wait until later, buddy. Remember, it’s family photo day, and your mom wants us to be on time. You’ve gotta freshen up first.”

Brody grinned. “All right, thought I bet I’ve grown a ton more since the last time!” His excitement was palpable. He couldn’t wait to see just how much more he’d gained in height and muscle.

Jaxon, Brody’s little brother, who had been watching the whole exchange with wide eyes, suddenly chimed in with his usual childlike enthusiasm. “Brody! You’re soooo tall now! You’re taller than Dad! Maybe you’ll be even as tall as the house?!” he asked, bouncing up and down in his chair.

Brody ruffled Jaxon’s hair and laughed. “Thanks, buddy! Who knows, maybe I’ll be taller than the whole neighbourhood soon!” His voice was full of playful confidence, but deep down, Brody couldn’t help but wonder how far this growth spurt would take him.

Jaxon’s eyes went even wider. “Whoa, that would be awesome!” he said, clearly in awe of his big brother.

Brody smiled warmly at his little brother’s excitement. “We’ll see, Jax. But either way, I’ll always be your big bro,” he said, giving Jaxon a reassuring wink before turning his attention back to his breakfast.

It was clear that Brody needed new clothes, and fast. His rapid growth had left most of his wardrobe useless, but they were pressed for time with the family photo session looming. At the mall, Brody couldn’t help but marvel at the transformation in his clothing size. Just a few months ago, he had been a comfortable medium, but now everything was too tight, too small.

As they reached the shoe store, Brody found himself grinning nervously when the sales associate brought out the foot-measuring device. Sliding his foot into place, he watched as the number crept higher. “Size 11,” the associate said with a chuckle. “Looks like you’re outgrowing your old shoes, Brody.”

Brody scratched the back of his neck, feeling a surge of pride and a little embarrassment. “Yeah, I guess I am,” he replied, trying to play it cool. But it was hard to ignore how quickly everything seemed to change; he was a teenager, after all!

As he moved on to the clothing section, he realised his top size had jumped from medium to large, and his trousers had done the same. He picked up a crisp white T-shirt, holding it up to his now broad chest, and couldn’t help but smile a little. It felt good, in a way—like all his hard work at the gym was paying off.

His mom ushered him toward the checkout, and with time running out before the photo session, Brody quickly grabbed the white T-shirt and a pair of blue sweatpants that would actually fit him. As they headed to the barbers, Brody glanced down at the clothes in his hands and thought about how much had changed in such a short time.

During his visit to the barber, Brody’s transformation was undeniable. The boy the barber had once hoisted into the chair was now towering at 6’6”, his broad shoulders barely fitting beneath the cape. The barber, who had known Brody since he was a toddler, almost didn’t recognise him.

“Whoa, Brody! You’ve shot up like a tree,” the barber said, astonished as Brody ducked slightly to fit through the door. As Brody sat down, the barber looked up at him with a grin. “What can I do for you today? New height, new look?”

Brody nodded, flashing a confident smile. “Yeah, I was thinking of something more grown-up. Maybe something that matches... all of this,” he said, gesturing to his imposing frame. His deepened voice and solid, muscular form made it clear he was far from the boy who used to come in for basic trims. “What about the beard aye?” he jokingly nudged Brody’s shoulder. “Are we keeping that?”

“Heck yeah!” Brody replied. There was no way he was losing the beard, especially with how long it had taken him to grow one in the first place, and now, seemingly, he could grow facial hair overnight!

The barber got to work, trimming Brody’s hair into a sharp, clean style. His new cut had a refined edge—short on the sides, neatly faded, and slightly longer on top, styled effortlessly to give him a mature, sleek appearance. The cut framed Brody’s strong jawline, making his intense features stand out even more.

As the barber finished and stepped back, he admired his work. “You’re looking sharp, Brody!” he said, impressed by how much the new haircut seemed to age Brody in a good way.

Brody ran his fingers through his freshly cut hair, the smoothness adding to his newfound sense of maturity. “Thanks, I really like it,” he replied, his grin wider now. The haircut didn’t just suit him—it elevated his entire look, giving him an air of confidence and masculinity that matched his towering height and athletic build.

As Brody left the salon, he caught his reflection in the window and couldn’t help but admire how much older he looked. The haircut had a way of aging him, but in a polished, sophisticated way. He no longer looked like the high school junior he was—he looked like someone who could be stepping into the world as an adult, strong and self-assured.

At the family photo session that Saturday afternoon, Brody towered over his family, a giant among them, beaming with pride as the camera flashed. His parents, once able to look him in the eye, now only stood at his shoulder height. His little brother, Jaxon, barely reached his waist, staring in awe at his big brother’s towering form. Brody couldn’t help but smirk as he noticed how small they all looked next to him. His broad shoulders and muscular frame filled the space between his family, making him feel larger than life.

As they returned home, Brody remained consumed by the doctor’s words. Eager to showcase his newfound physique, he headed to his room. Stripping to his new underwear, Brody stood before the mirror, fueled by newfound confidence.

Flexing each muscle group in turn, Brody marvelled at his amazing reflection. His biceps and triceps had gained impressive definition, his pecs looked more chiselled, and even his legs had bulked out.

Unable to contain his excitement, Brody shared his progress on social media. With each flex, he snapped photos to capture the transformation. As he posed, he couldn’t help but notice even his bulge seemed more pronounced—a surprising yet welcome development.

Posting the images online, Brody felt a surge of pride as the likes and comments poured in. “This is wild,” he thought to himself.

Brody had time for a quick evening workout, his body still humming with energy despite the day’s events. Since he had hit his lower body and back hard the day before, it was time to focus on chest and arms today. He kicked things off with a set of rapid-fire sit-ups, blasting his abs harder than ever before. His body moved like a machine, muscles contracting and releasing perfectly. He lost count after 110, maybe more, but his speed was mind-blowing. After 10 minutes of nonstop sit-ups, Brody finally stopped, but not because he was tired—he’d easily cranked out something like 600 sit-ups. He only paused because the pump in his abs felt perfect.

Next, Brody warmed up his chest by adding butterfly extensions on his Dad’s Bowflex. The first set of 15 reps felt solid, nearly maxing out the machine’s resistance, but that wasn’t enough for Brody. He cranked it to maximum resistance and powered through 2 sets of 10. The pump was real—his tank top stretched tighter across his chest with each rep, seams straining from the sheer size of his muscles.

Lying back on the bench, Brody picked up two 80lb dumbbells for chest raises. The first set felt easy, so he upped the weight to 100 pounds for the next two sets. Each lift felt like a rush of power surging through his chest. “Fuck! I feel even stronger than yesterday, way stronger!” Brody grunted, the raw strength coursing through him as he pushed the weights higher.

Not satisfied yet, he grabbed the same 100lb dumbbells and moved straight into bicep curls. Each rep sent his arms swelling with blood, his veins popping as he easily completed a dozen reps on each arm. His biceps were throbbing, and the pump was unreal. Brody paused and flexed both arms in a double biceps pose, sitting on his bench.

“Wow! Those arms are definitely bigger than before! They’re huge!” he marvelled, staring at his reflection in awe. His biceps had to be over 18 inches now, and he couldn’t help but grin at his transformation. He was growing stronger and bigger every day, and he loved every second of it. His workout lasted much longer than expected, and the height check would have to wait until tomorrow.

 

Part 6

The following day, Brody woke up with a fresh wave of determination coursing through him. His oversized frame sprawled across his bed, the morning light streaming through the curtains casting shadows over his rippling muscles. As he stretched, the bed creaked beneath his weight—a daily reminder of how quickly he was outgrowing the world around him. Today was a rest day, but Brody knew rest wasn’t about doing nothing; it was about recalibration. He had an entire morning to dig deeper into the mechanics of fitness, growth, and how to wield the potential of his unprecedented transformation.

Sitting at his desk, now slightly too small for his expanding build, Brody began scouring the internet. The keyboard looked comically small under his large hands, but his focus never wavered. Fitness forums, expert blogs, and transformation videos captured his attention, their motivational messages reverberating in his mind. The clinking of weights in the background of workout tutorials felt like a soundtrack to his own journey. Each click, each article, seemed to spark an idea on how he could sculpt his already awe-inspiring body into something even more extraordinary.

He jotted down notes, tweaking his routines to accommodate his rapid growth. His mind buzzed with possibilities—should he increase his protein intake to match his metabolism? Should he focus on hypertrophy training, or would strength-based lifts better fuel his gigantism? A particular article about form and muscle recovery caught his eye, and he leaned closer, engrossed. The science of his body fascinated him as much as the results did.

By mid-morning, Brody leaned back in his chair, cracking his knuckles and glancing down at his arms. Even at rest, they bulged with veins, and the striations in his biceps seemed to deepen with every flex. “This is just the beginning,” he murmured to himself, his grin widening. He couldn’t shake the thrill of imagining what he might become, the heights he might reach—literally and figuratively.

The house buzzed with energy that afternoon as his parents decided to seize the cheerful mood for a family photoshoot. The living room became an impromptu studio, filled with laughter and playful teasing. Brody, ever the good sport, joined in, towering over everyone as he tried to crouch low enough to fit in the frame.

“Brody, you’re practically bending in half to fit!” his mom teased, ruffling his hair like she used to when he was a child—though now, she had to stretch to reach him. “Can we even get you and your dad in the same shot anymore?”

Grinning, Brody puffed out his chest dramatically. “Guess I need to start bringing a stool for you guys to stand on,” he joked, his deepened voice resonating through the room. He crouched slightly for another picture, his broad shoulders filling the frame, dwarfing his little brother, Jaxon, who barely reached his waist.

His dad shook his head with a chuckle, reaching up to rest a hand on Brody’s shoulder. “Son, you’re making it harder for your old man to keep up. I used to be able to reach your head. Now, I’m not even close!” He gestured toward the kitchen wall where the family’s growth chart stood. “Why don’t we check how much taller you’ve gotten? I think it’s safe to say you’re breaking some records around here.”

Brody perked up at the suggestion, excitement gleaming in his eyes. “Absolutely! Let’s do it,” he said, striding toward the chart with his parents and Jaxon trailing behind.

As Brody stood against the wall, his dad grabbed a pencil and a small stool to reach the top of his head. The scene felt surreal—just a year ago, Brody had barely brushed 5 feet tall. Now, his dad had to crane his neck upward to meet his gaze.

With a soft scrape, the pencil marked the wall. His dad stepped back, his expression a mixture of pride and disbelief. “6-foot-8,” he announced, his voice almost trembling. The words hung in the air like a declaration.

Brody blinked in surprise, then broke into a wide grin. “Two inches in a day? Are you serious?” He flexed a bicep for emphasis, the muscle swelling under his skin. “Gigantism’s really working overtime, huh?”

His mom’s mouth hung open for a moment before she managed a chuckle. “Brody, you’re unbelievable,” she said, shaking her head. “You’re going to be taller than the house at this rate.”

His dad laughed but then placed a hand on Brody’s shoulder. “You’re becoming something else entirely, son,” he said, his voice filled with pride and a touch of awe. “But remember, this growth isn’t just about getting bigger. It’s about learning how to handle it—how to channel all this potential into something great.”

Brody nodded, though his mind was already racing ahead. If he could grow this much in a single day, what would tomorrow hold? As he gazed at the measurement line far above the others on the wall, a quiet voice inside him whispered: This is just the beginning.

 

Part 7

Brody approached the next day with unshakable resolve, his body thrumming with energy from the previous day’s insights. The lingering ache in his muscles wasn’t a sign of fatigue—it was a badge of honour, proof that he was transforming. Each day felt like an opportunity to carve out something extraordinary, and today was no different. The relentless pace of his growth was exhilarating, and Brody was determined to seize every ounce of potential his gigantism offered.

Armed with a plan fine-tuned by yesterday’s research, he set his sights on an intense upper-body workout. The air in the garage gym was cool, but Brody’s body radiated heat as he threw himself into his warm-up. Today wasn’t just about lifting weights; it was about pushing boundaries.

He began with sit-ups, determined to surpass his previous record. His core burned like molten steel, but Brody powered through, moving with mechanical precision. Sweat dripped down his chiselled abs, pooling on the mat as the count ticked higher. By the ten-minute mark, he’d smashed his previous achievement with an incredible 700 sit-ups—100 more than yesterday. His stomach felt like a slab of carved granite, and the sheer intensity of the burn sent a thrill through him.

Not one to stop at a personal best, Brody turned to his dad’s Bowflex machine with determination. The clatter of adjusting weights echoed through the garage as he cranked the resistance to its maximum setting. His first set of butterfly extensions tested his limits, but he didn’t back down. With veins bulging along his forearms and chest, he powered through 18 reps, exceeding yesterday’s effort. By the time he finished two more sets of 12, his tank top was stretched so tight across his chest it looked ready to split. The seams strained audibly, but Brody couldn’t help but grin.

Next, he grabbed the 90-pound dumbbells for chest raises, lifting them with ease. The first set felt strong, but his hunger for progress was unrelenting. He upped the weight to 110lbs, his massive arms trembling slightly under the strain but still powering through with perfect form. His chest swelled with every rep, the rush of blood making his pecs look even fuller. He caught sight of himself in the mirror, veins snaking over his skin like tributaries of raw power.

But Brody wasn’t done. He reached for the same 110lb dumbbells and transitioned into bicep curls. Each rep sent a fiery pump through his arms, his biceps swelling larger with every contraction. By the end of 15 reps on each arm, his veins stood out like ropes, his biceps now easily 19 inches around. He stared at his reflection, flexing to admire the peaks of his growing arms. “This is insane,” he murmured, his voice heavy with awe and excitement. “I’m growing faster than I ever imagined.”

After his intense workout, Brody retreated to the privacy of his room for some much-needed rest and reflection. The thought of his growth spurt wasn’t just exciting—it was intoxicating. Standing before the mirror, he took in every detail of his transformation: the bulging muscles, the broader chest, and even the subtle changes in his posture that made him look more commanding.

But Brody wasn’t done rewarding himself. With a cheeky grin, he decided to focus on another muscle group—one hiding beneath his underwear. He chuckled as he realised his growth spurt wasn’t limited to just his height and strength. His dick was growing too, a fact that sent an amused and excited thrill through him. This wasn’t entirely new, but he’d struggled in the past to feel arousal from the typical fantasies involving women. It wasn’t until recently that Brody had come to understand his preferences—he was gay.

Today, his mind was a whirlwind of thoughts about gigantism, the thrill of towering over his peers, and the undeniable power that came with his transformation. The mental image of his dominant stature sent a rush of excitement through him. It wasn’t long before his body responded, the pleasure building quickly and intensely.

With a sudden release, sploosh, Brody reached his climax, his lower abdomen covered in cum. A warm satisfaction spread through him as he caught his breath, a smile tugging at the corners of his mouth. “I should do this more often,” he thought, relishing the moment of self-discovery. This wasn’t just about physical pleasure—it was an affirmation of his identity and his growing comfort in his rapidly changing body.

Refreshed from a shower and fuelled by a hearty lunch, Brody ventured out for his first session at the local gym. It was just a five-minute walk from his house, but stepping inside felt like entering a new world. The gleaming equipment, the hum of conversations, and the rhythmic clink of weights created an atmosphere of ambition.

Brody felt the eyes of the older gym-goers on him as he made his way to the weights area. Though most of the patrons were seasoned lifters, he held his own with a quiet confidence. “Hey, mate, you new here?” a middle-aged man asked as Brody adjusted the weights on the lat pulldown machine.

“Yeah, just joined today,” Brody replied, his voice deep but still carrying the enthusiasm of youth.

The man nodded approvingly. “Good to see someone your age taking fitness seriously. Keep at it, and you’ll go far.”

Brody smirked to himself, thinking, Far? Mate, you don’t even know.

But the truth was, Brody didn’t really know just how far gigantism was going to take him.

Brody dove into his workout, tackling leg extensions, lat raises, and chest flys with precision. The advanced equipment offered challenges that his garage gym couldn’t, and he relished every moment of it. The camaraderie of the older lifters inspired him, but he didn’t need their validation. He was growing—literally—whether he worked out or not. Still, the gym gave him an outlet for his drive, a place to refine the power coursing through him.

By the time he returned home, his body hummed with exhaustion and satisfaction. His parents were eager to hear about his experience, their curiosity blending with the pride they couldn’t hide. Brody shared stories of his workout, leaving out the parts about the awe-struck stares he’d received.

“You’re really embracing this, aren’t you?” his dad asked, a mix of admiration and concern in his voice.

Brody grinned, his massive frame filling the doorway. “Of course. I’ve got to keep up with this growth, right? Who knows where it’ll take me?”

His parents exchanged a glance but said nothing. The day had worn Brody out, and he crashed into bed shortly after dinner. As he drifted to sleep, his muscles twitched and pulsed, his body working tirelessly even in rest. His dreams were filled with images of towering over the world, each step shaking the ground.

When morning came, Brody woke with the distinct feeling that he was bigger than the night before. And if the snugness of his clothes was any indication, he was right.

 

Part 8

As the first light of morning streamed through his window, Brody awoke with a surge of anticipation. He stretched, feeling the tight fullness in his muscles—a testament to his relentless workouts and the miraculous effects of his gigantism. His body felt powerful, almost electric, as if it were buzzing with potential. He couldn’t wait to see just how much he’d grown overnight.

Swinging his legs out of bed, his feet thudded against the floorboards with a heavier impact than the day before. He dropped to the floor without hesitation, cranking out 50 press-ups with ease, his chest muscles pumping like pistons. Each rep sent a ripple through his pecs, making them feel harder and fuller. Flipping onto his back, he blasted through 50 tricep dips next, his arms barely registering the strain as his body moved like a finely tuned machine.

Curious to quantify his gains, Brody grabbed his measuring tape and wrapped it around his flexed bicep. His eyes widened as he read the number: 20 inches. “No way!” he muttered, grinning from ear to ear. He’d gained a full inch overnight—his biceps swelling like balloons, his triceps and forearms thickening in proportion.

Stepping closer to his mirror, he flexed and marveled at the dramatic changes in his upper body. His back had grown broader, his lats flaring out like the hood of a cobra, and his chest—bloody hell!—now spanned a staggering 70 inches. His pecs looked like armour plates, full and round, commanding attention even in the confines of his small bedroom.

Finally, Brody stepped onto his scale, his heart pounding with anticipation. The digital numbers flickered before settling on a figure that made his jaw drop. 218 pounds. Four days ago, he’d weighed 142. He’d gained 76 pounds in less than a week.

“This is insane!” he exclaimed, his voice booming with excitement. He struck a double bicep pose in the mirror, his broad shoulders framing a perfect V-taper. His waist had narrowed in comparison, enhancing the striking proportions of his torso. He looked every bit like a superhero, his body bulging with raw power, his towering frame an imposing monument to his transformation.

Flexing through a series of poses, Brody couldn’t help but laugh with exhilaration. Each muscle popped, his veins snaking across his arms and chest like a roadmap of strength. “This is crazy!” he said again, his grin growing wider. He felt invincible, as if nothing could stop him. With a roar of triumph, Brody struck a most-muscular pose, his entire body rippling with power.

After a refreshing shower, Brody searched his wardrobe for something that still fit. Thankfully, he found a loose-fitting hoodie and sweatpants that, while snug, didn’t rip. As he dressed, his thoughts drifted to the arrival of his relatives, and he couldn’t wait to see their reactions.

When his uncle, aunt, and toddler cousin Cruz arrived, the shock on their faces was immediate and palpable. “Brody, what on earth have you been eating? Rocks?” his uncle teased, his eyes scanning Brody’s massive frame with a mixture of awe and disbelief.

Brody laughed, scratching the back of his head. “Just a lot of food and a lot of gym time,” he replied, trying to play it cool.

His aunt, Lisa, gasped as she stepped into the living room. “I can’t believe this is the same Brody! You look like a completely different person,” she said, shaking her head in amazement.

Blushing slightly but proud of his progress, Brody shrugged. “Thanks, Aunt Lisa. I’ve just been really focused on staying fit.”

Cruz, who had been clinging shyly to his mum’s leg, finally looked up at Brody with wide eyes. “Brody strong!” he declared, his little voice filled with awe.

Everyone laughed, and Brody bent down to pick up his cousin effortlessly, lifting him high above his head. “What do you think, Cruz? Are my arms bigger than your head?” he joked, flexing one arm for comparison.

The lunch spread was lively, filled with chatter and laughter, though the conversation inevitably turned to Brody’s transformation. His parents dropped the bombshell about his gigantism diagnosis, leaving his relatives wide-eyed and stunned. Jaxon, Brody’s eight-year-old brother, listened intently, his expression a mix of fascination and confusion.

Later, as the family lingered over tea, Jaxon approached Brody with innocent curiosity. “Can’t you shrink back down to your old size?” he asked, his voice quiet but hopeful.

Brody crouched down, trying to explain in simple terms. “It doesn’t work like that, buddy. Once you start growing, you can’t really go back.”

Jaxon tilted his head, his wide eyes locking on his brother’s towering frame. “How big will you get?”

Brody chuckled, enjoying his brother’s wonder. “I don’t know,” he said playfully. “But imagine if I grew as tall as our house!”

Jaxon’s jaw dropped. “Really?!”

With a mischievous grin, Brody leaned closer. “Maybe. Who knows? I could grow as tall as a building... maybe even a skyscraper!”

Jaxon stared in awe, momentarily lost for words before blurting, “That would be so cool!”

Later that evening, Brody found himself pacing the kitchen, a restless energy gnawing at him. Despite everything—the growth, the strength, the admiration—something inside him craved more. His uncle joined him, watching as Brody flexed absently, seeking validation.

“Brody, you’re doing fine,” his uncle reassured him. “Look at you—you’ve made incredible progress. With this gigantism, who knows? You’ve probably got more growth ahead.”

Brody frowned, flexing his arm and watching the muscle bulge impressively. “I just wish it would go faster,” he admitted. “Look at me—I want more!”

His dad, who had overheard from the doorway, stepped in. “Brody,” he said, his tone firm but kind, “you’re already doing great. These things take time, and you’ve already achieved so much. Be patient with yourself.”

Brody nodded, but his mind was still restless. After retreating to his room, he stared into his mirror, flexing and posing as if to reassure himself. He took a few photos to share on social media, the perfect lighting highlighting every ridge and curve of his powerful physique. But even as the likes poured in, the nagging hunger for more didn’t fade.

Lying in bed that night, Brody stared at the ceiling, questioning if he was doing enough. Was he eating enough? Training hard enough? The thought of falling short of his potential gnawed at him, feeding his insatiable drive.

As if his body had heard his plea, Brody’s gigantism responded overnight. Unbeknownst to him, his body underwent another astonishing surge. By morning, he had grown another three inches and packed on an additional 53 pounds of pure muscle.

When he awoke, the snugness of his clothes and the weight of his own body told him everything he needed to know. Brody swung his legs out of bed, ready to discover just how much further his transformation had taken him.

 

Part 9

Brody’s feet, once a modest size 7 when he’d begun his fitness journey, now dwarfed even his previous footprints. At a staggering 13 inches long, he now required size 15 shoes. The changes weren’t limited to his height or muscles—his entire body had grown, his bones, joints, and sheer physical presence expanding at an almost unbelievable rate. And then there was his weight: Brody had packed on nearly 60 pounds of pure, dense mass in just two days, a rate of growth that defied logic.

As he stood in front of the mirror, Brody couldn’t help but admire the impossible. His arms, now thicker than his own head, bulged with veins that pulsed beneath his skin like rivers of power. Flexing his biceps, he let out a soft whistle. “Look at these things,” he muttered, turning to inspect the rest of his body.

His chest rose and fell with controlled breaths, his pecs protruding like slabs of granite, full and rounded. His legs—massive pillars of muscle—looked ready to crush anything in their path, and his back spread out like wings, giving him the imposing silhouette of a titan.

Turning slightly, Brody struck a most-muscular pose. Every muscle in his body popped, his pecs surging forward, his shoulders broadening even further, and his lats flaring dramatically. His reflection seemed larger than life. “This is nuts,” he said to himself, a grin spreading across his face. “Nearly 60 pounds in two days... what the hell is even happening to me?”

His gaze travelled downward, catching on the stretched fabric of his trunks. His glutes strained against the material, but it was the growing bulge in the crotch area that truly drew his attention. The fabric seemed to struggle to contain him. Brody chuckled, adjusting himself in the mirror. “Guess I’m growing everywhere,” he quipped, shaking his head.

Unable to contain his excitement, Brody scrambled to get dressed. He grabbed the white T-shirt he’d bought only a few days earlier and attempted to slip it on. As the material stretched over his shoulders, the seams immediately began to groan. By the time he forced it over his chest, the sleeves gave out completely, ripping apart to reveal his massive biceps.

“No freaking way! This is awesome!” Brody exclaimed, flexing his arms in the mirror, his grin widening as he admired the shredded fabric dangling from his shoulders.

Bursting with energy, Brody bolted downstairs, his heavy footsteps reverberating through the house. “Mum! Dad! You won’t believe it—I’ve grown again!” he shouted, his booming voice echoing through the halls.

His parents, who had grown somewhat used to Brody’s daily growth updates, exchanged amused yet astonished glances as he stormed into the living room. “Brody, look at your shirt!” his mum exclaimed, gesturing at the ruined fabric.

“Yeah, it couldn’t handle the gains,” Brody replied with a laugh, flexing dramatically. “Over 60 pounds in two days! Can you believe that?!”

His dad raised an eyebrow. “60 pounds?” he repeated, struggling to wrap his head around the figure. “That’s... that’s insane, Brody. You were what, 218 pounds two days ago?”

“Yep, and now I’m 271!” Brody said proudly. “It’s like I’m growing faster every day!”

His mum frowned slightly, concern flickering across her face despite her son’s enthusiasm. “We’re going to need to keep track of this, Brody. It’s not just about your size—it’s the speed of it. You’re putting on more weight in days than most people do in years.”

Brody’s dad nodded in agreement. “Your mum’s right, son. We’re proud of your progress, but this growth... it’s not normal.”

“Normal?” Brody laughed, flexing his chest and letting the tattered remains of his shirt fall to the floor. “There’s nothing normal about me anymore, Dad. And I’m loving every second of it.”

His mum sighed, gesturing toward the stairs. “Right, well, before you rip through the rest of your clothes, why don’t you head down to the Big’N’Tall shop and get something that fits? And for heaven’s sake, Brody, don’t flex while you’re trying things on!”

The Big’N’Tall shop felt surreal as Brody stepped inside. He couldn’t help but marvel at how much his perspective had shifted in such a short time. This was a store he’d gawked at as a child, its oversized mannequins and towering racks once seeming impossibly large. Now, it felt like home—a place made for giants like him.

The shop assistant, an imposing figure at 6’7, glanced up at Brody and froze for a moment, his eyes widening slightly. “You... uh, looking for something specific?” he asked, his voice tinged with curiosity.

“Yeah, something that won’t rip when I breathe,” Brody replied with a grin, gesturing at his exposed chest and arms.

The assistant chuckled, leading Brody toward the larger sizes. “Well, you’ve definitely come to the right place. Though, I have to say, we don’t get many teenagers your size.”

Brody smirked, running a hand over one of the compression tops on display. “Yeah, I’m a bit of a special case.”

He explored the racks, selecting XL, XXL, and even XXXL tops, along with oversized sweatpants, jackets, and jeans. In the changing room, he tried on a long-sleeve compression top, the elastic fabric moulding perfectly to his muscles. The way it clung to his pecs and arms sent a thrill through him. “Damn,” he whispered, turning in the mirror. His reflection looked like a fitness model on steroids.

As he checked out, Brody couldn’t resist grabbing a stash of protein powders, drinks, and bars from the display by the counter. “Might as well fuel up,” he said, adding the haul to his growing pile of purchases.

Back home, Brody wasted no time diving into a brutal workout. The garage gym echoed with the clinking of weights and Brody’s determined grunts as he pushed himself harder than ever.

Five sets of tricep extensions and three sets of bicep curls with 160-pound dumbbells left his arms pumped and throbbing with power. He followed up with five sets of shoulder flys, his super-wide torso gaining an almost cartoonish breadth. Barrel curling 150 pounds for two sets of 18 reps sent his biceps bulging even further, while butterfly extensions on the Bowflex left his chest feeling like it was on fire.

The workout culminated in his biggest triumph yet: a 400-pound bench press for six reps, followed by a jaw-dropping 450-pound single rep. As he set the bar down with a triumphant roar, Brody couldn’t help but laugh. “What’s next? Five hundred?”

That evening, Brody strode into the dining room in his new grey tank top, his muscles still pumped from the workout. His parents couldn’t help but stare as he sat down, his shoulders nearly blocking their view of the table.

“Guess what I did today,” Brody said between bites of food. “Benched 450 pounds!”

His dad shook his head in amazement. “Brody, that’s incredible. You’re turning into a powerhouse. Maybe it’s time to think about some competitions.”

Brody grinned. “Maybe. But I think I’ve got a bit more growing to do first.”

After dinner, his parents asked for a posing routine, and Brody gladly obliged. As he moved through each pose, his muscles seemed to grow even larger under their admiring eyes. By the time he finished with a most-muscular pose, his parents were clapping, though their concern was evident.

Later, as Brody headed upstairs, his parents exchanged worried glances. Though proud of their son’s progress, the speed of his growth left them uneasy.

Unbeknownst to them all, Brody had already surpassed 280 pounds.

 

Part 10

As dawn broke, Brody slept like a log, the fatigue from the previous day’s intense workout lulling him into a deep slumber. However, as the first rays of sunlight filtered into his room, he awoke with an eagerness that had become characteristic of his gigantism journey.

Without wasting any time, Brody slipped into his red underwear, a garment that seemed to become more snug with each passing day. The fabric clung to his expanding muscles, accentuating the incredible gains he had made. Eager to capitalise on the morning energy, he embarked on a half-hour weightlifting session, focusing on exercises that would pump up his muscles.

Post-workout, Brody stood in front of the mirror, admiring the reflection that stared back at him. His physique, now a testament to relentless dedication, filled him with a sense of pride and accomplishment. As he posed, capturing the pumped-up state of his muscles, he couldn’t help but express his thoughts aloud.

“Man, I can’t believe how big I’m getting. Gigantism is amazing!” Brody exclaimed, his voice reflecting a mix of excitement and satisfaction. “I love this feeling and can’t wait to grow even bigger. Imagine how incredible it’ll be!”

His eyes locked onto the mirror, Brody continued to pose, each flex revealing the progress of his journey. The desire to embrace gigantism and push the boundaries of his own growth fueled his enthusiasm. As he stood there, produly looking at the changes his body was undergoing, Brody’s determination to become even larger resonated in the words he spoke and the poses he struck.

After devouring a protein-filled breakfast, Brody wasted no time and headed straight to his garage gym. The weightlifting session was intense, lasting for several hours. Brody took breaks only to refuel with protein bars or shakes, relentlessly focusing on his goal. During his workout, thoughts of the doctor’s words lingered in his mind, a constant reminder of his extraordinary journey.

As the hours passed, Brody started feeling the drain on his energy, and his muscles ached from the rigorous exercise. His father, who had been occupied with work, finally had the opportunity to measure Brody’s height after a four-day hiatus. Brody stood proudly against the wall, and his Dad quickly realised he needed something to stand on to reach his son’s head.

With a makeshift platform, his Dad managed to mark the line where Brody’s head met the wall. As he stepped back to inspect the measurement, his jaw dropped in disbelief. Brody’s height now stood at an astounding 7 feet 3 inches! Shocked, his Dad looked at Brody his eyes stretching from his crotch upwards, Brody cheekily grinned in response.

“Dad, it looks like I’m not stopping anytime soon! Gigantism’s doing wonders,” Brody exclaimed, embracing the incredible growth he was experiencing.

Eager to showcase his progress, Brody flexed his muscles, revealing the remarkable development of his physique. His Dad, unable to believe his eyes, marvelled at the transformation unfolding before him. His massive arms were now 22 inches around!

The excitement continued as Brody stepped onto the scale. The needle climbed past 290, then 300, before settling on 308 pounds. Brody, overwhelmed with pride, couldn’t contain his enthusiasm. “I’ve broken the 300 mark!” he shouted; his parents left in a state of shock.

 

Part 11

It had been 25 days since Christmas, though for Brody, it felt like a lifetime. The scrawny, five-foot-tall teenager he once was seemed like a distant memory. Standing in his bedroom mirror that morning, the changes were undeniable. Flexing his huge muscles he was filled with pride. His building arms, bigger than his own head bulged as he crunched his abs, his pits now full of hair filled with a musky scent.

His reflection told a story of transformation: his jawline was sharper, more masculine, and his freshly cut hair gave him a polished, older appearance. His bodybuilder-like physique seemed surreal, the kind you’d expect to see on a professional athlete—not a 16-year-old. He ran a hand over his stubbled jaw, grinning.

Picking up his phone, Brody opened Simtagram, a platform where his growing following had been eagerly awaiting updates. He struck a most muscular pose, the camera catching every bulging vein and thick muscle as his green T-shirt stretched to its limits. “Morning pump,” he captioned, tagging it with #gains #unstoppable #gigantism. Within minutes, the post was flooded with comments:

“Damn, Brody, you’re huge!”

“What are you eating?! I need the recipe!”

“Are you even human anymore?”

Brody chuckled, tossing his phone onto his bed. “Not human anymore,” he muttered to himself. “Something better.”

That afternoon, Brody headed to school for the first time in weeks.Getting changed forl, his dark green T-shirt hugged his upper body like a second skin, straining over his chest and arms, while his white chino shorts clung to his massive quads. He turned sideways, the shirt rising slightly to reveal his tight, chiselled midsection, and smirked.

It wasn’t a normal school day—only a handful of pupils had to attend for exam revision, himself included. Despite knowing most of his classmates, Brody wondered if they’d even recognise him now.

The walk to school was quick; he dwarfed the pavement with each step, the weight of his body making a rhythmic thud as his sneakers struck the ground. As he entered the building, heads turned. Whispers followed him down the hallway, a mix of awe and disbelief.

“Is that... Brody?”

“No way. He looks like a tank!”

“Since when did he get that big?”

In the revision room, Brody took a seat near the back, his sheer size making the desk and chair seem comically small. His broad shoulders stretched far beyond the edges of the seat, his massive thighs barely fitting under the table. Even though he’d dressed relatively casually in a dark green T-shirt and white chino shorts, the clothes clung to his muscles like they’d been painted on. His presence commanded attention, whether he wanted it or not.

Mr. Thompson, the teacher overseeing the session, glanced at Brody more than once as he explained the material. What a sight, it wasn’t just Brody’s sheer size that made him unrecognisable—his chiselled face and confident posture made him seem like an entirely different person.

During a break after the first session, one of Brody’s classmates, Jason, approached him. Jason was average height—around 5’8”—but standing next to Brody, who loomed over him at 7’3”, he looked childlike.

“Brody,” Jason began hesitantly, his eyes darting to Brody’s chest, “you, uh... you’re huge, man. Like... massive. How’d you get like this?”

Brody grinned, flexing his arm slightly. The movement alone was enough to make Jason step back in amazement. “Hard work, the gym, protein shakes,” Brody said, keeping it simple.

Jason swallowed hard, clearly nervous but intrigued. “Can you... uh... can you show me? Like, pose or something?”

Brody raised an eyebrow, then stood up, towering over Jason. With a confident grin, he yanked off his shirt, letting it drop to the floor. The sight of his bronzed, shredded torso made Jason’s jaw drop.

“Fine,” Brody said, striking a majestic side-chest pose, his pecs flexing and heaving and his arms swelling as veins snaked across his biceps. The pose emphasised the sheer width of his shoulders and the tightness of his waist, making him look even more massive.

Jason clapped awkwardly, his face a mix of awe and disbelief. “Holy crap, Brody! You’re like a superhero.”

For the second revision session, Brody decided not to bother with his shirt at all. He walked smugly into the classroom shirtless, his muscles gleaming under the fluorescent lights, something he;d ever dreamed of really doing before. His traps and shoulders rose like mountains, and his abs—carved with precision—caught the attention of everyone, including Mr. Thompson again.

The teacher hesitated, clearing his throat awkwardly. “Brody, uh...” He trailed off, realising there wasn’t much he could say. Technically, Brody wasn’t breaking any rules. Instead, Mr. Thompson resumed his lesson, though his gaze frequently wandered to Brody’s enormous frame.

Brody smirked to himself, aware of the effect he was having. Between notes and practice exams, he downed protein shakes—one after another, as if his body couldn’t function without them. “Fuel for the machine,” he said proudly, stacking the empty bottles at his feet.

After the revisions, Brody returned home, his parents waiting to head out for another family photo session. Liz and Tom had been keen on documenting his transformation, though they still struggled to process the reality of their son’s rapid growth.

Standing in front of the camera, Brody towered over his family. Jaxon, who was now 4’4”, barely reached Brody’s calf, and his parents—Liz at 5’2” and Tom at 5’10”—only came up to his elbows.

“All right, everyone smile!” the photographer said, though even he seemed distracted by Brody’s immense presence.

Jaxon reached up and touched Brody’s massive calf. “Brody, you’re huge,” he said, his voice filled with wonder.

Brody smiled warmly. “Cool, isn’t it, man.” He winked, striking a casual double biceps pose as the camera flashed.

Tom looked up at his son, shaking his head. “I swear, Brody, you grow more every day.”

“Yeah, Dad,” Brody said, grinning. “And I’m not stopping anytime soon.”

Liz sighed, half-amused, half-concerned. “Just don’t outgrow the house, okay?”

Brody chuckled. “No promises, Mum. No promises.”

As the session ended, the family headed home, Liz and Tom exchanging quiet glances. While Brody showed no signs of slowing down, his parents couldn’t help but wonder: how much bigger could their son possibly get?

 

Part 12

It had been 14 days since the last doctor’s visit, and unbeknownst to Brody, his parents had scheduled another appointment with Dr. Harrison for the following day. Liz and Tom had agreed that monitoring Brody’s rapid growth was no longer just a curiosity—it was a necessity. They hadn’t mentioned it to him yet, though. Not that he’d resist. If anything, Brody enjoyed the attention and learning about his ever-expanding stats.

For Brody, the rest of the day was singularly focused: size. After the family photo session where his towering figure had stolen the spotlight, he went straight to the garage gym. Today’s targets: legs and chest.

The rhythmic clinking of weights filled the space as Brody powered through squats. The barbell bent slightly under the sheer weight—400 pounds was no longer enough, so he’d piled on more plates. Each repetition was a test of his body’s ability to adapt, his quads and hamstrings bulging with every controlled descent and powerful rise.

“Come on,” he psyched himself up, under his breath, driving through another rep. Thick veins snaked down his neck and his thighs like cords of steel, pumping life into his expanding muscles.

Switching to chest exercises, Brody laid on the bench press and stared up at the bar, stacked with 450 pounds. A weight that would terrify most people. But Brody was no longer like most people. Exhaling deeply, he gripped the bar tightly and pushed, his pecs flaring with every lift. Each contraction felt electric, his chest fibres burning with that intoxicating pump that told him he was getting stronger.

Later that evening, with his workout obliterated, Brody strode into the kitchen, still clad in just his boxer briefs. The fabric stretched taut over his massive glutes and thighs, threatening to give way with each step. The kitchen—once comfortably proportioned—now seemed like a dollhouse.

Brody paused in the doorway, a faint smile tugging at his lips. He could still remember sitting at the counter as a kid, his feet dangling off the high stool as he begged his mum for another cookie. Back then, everything had felt so big—like the shelves that had seemed impossible to reach or the towering fridge that felt like a giant’s treasure chest.

Now, those same shelves were laughably low, the counter barely reached his waist, and the fridge handle fit awkwardly in his massive hand, as if it had shrunk. The room hadn’t changed, but he had outgrown it in every way.

“This kitchen’s shrinking, or I’m growing way too fast”, Brody thought, grabbing a protein bar in one hand and a loaf of bread in the other. “At this rate, I’ll outgrow the whole damn house.”

Leaning over the counter, devouring bread slice by slice, he let out a satisfied sigh. Each bite felt like fuel for the furnace inside him, building his body stronger.

“Brody.” Liz’s voice startled him mid-bite.

He turned to see his mum standing in the doorway, arms crossed and one eyebrow raised.

“That’s the second time you’ve raided the kitchen today,” she said, half-scolding, half-marvelling at the sheer amount of food he was consuming.

Crumbs clinging to his grin, Brody shoved the last of the protein bar into his mouth. “What can I say, Mum? I’m a growing boy.”

Liz sighed, shaking her head. “That’s an understatement.”

Her eyes lingered on his broad shoulders and massive frame, taking in how he dwarfed the small room. Even hunched over, he seemed too big for the space. Brody, meanwhile, was already back at the cupboard, rummaging for more food.

By the time the house quietened for the night, Brody wasn’t ready to stop. Back in his room, he dropped to the floor, locking his feet under the bedframe for sit-ups. His abs rippled like armour plates under his glistening skin, sweat catching the dim light.

Let’s hit 1,000 tonight.

The burning in his core pushed him onward, each rep another brick in his temple of power. By the time he reached 500, his entire midsection was aflame, but he refused to stop.

At 800, he paused, lying flat for a moment as his chest heaved. Staring at the ceiling, his mind wandered. How far can I go? How big can I get? Taller, stronger, thicker... is there even a limit?

The thought didn’t intimidate him—it exhilarated him. He imagined towering over everyone, his classmates, his teachers, even his own house. It wasn’t arrogance; it was a hunger, pure and unrelenting.

Grinning, he finished his final set, his heart pounding with satisfaction as he hit 1,000 push ups!

As he stretched out on his bed, muscles throbbing from the day’s efforts, he glanced at his phone. His Simtagram post had exploded with likes, the comments a mixture of awe and envy.

Brody had no idea what tomorrow’s doctor’s visit would reveal about his transformation. But for now, he welcomed sleep, his body pulling him into its deep, weighty embrace.

 

Part 13

Brody loomed in the waiting room of the doctor’s office, a colossus among average-sized people. His black compression top stretched over his chest like a second skin, its sleeves extending all the way to his wrists, though they were pushed up slightly by the sheer size of his forearms. The top hugged every inch of his torso, accentuating the defined ridges of his abs and the vast, striated curves of his pecs. His black athletic shorts barely reached mid-thigh, exposing legs thick with rippling muscle and increasingly coarse, dark hair.

When Brody sat down, the chair groaned audibly under his weight, the sound drawing the attention of every person in the waiting room. He adjusted his seat, stretching out his long legs, which brushed against the chairs in front of him. Leaning back casually, he turned to his parents with a smirk and raised one massive arm.

“Look at this,” he said, flexing deliberately. The compression fabric pulled tight as his bicep rose, the muscle swelling into a massive, veiny peak. “I swear, every time I do this, it feels bigger than the last time. Crazy, right?”

Liz tried to respond, but the words caught in her throat. Tom cleared his throat. “Uh, yeah, Brody. That’s... something. I don’t know how to explain it, but you’re... enormous.”

“Thanks, Dad,” Brody said, grinning as he flexed again, enjoying the way the veins along his arm seemed to pulse with life. “I mean, it’s not like I’m trying to make people stare, but I guess it’s hard not to, huh?”

Liz shook her head, half in awe and half in disbelief. “Brody, the way you’re growing, I don’t even think this office is going to fit you next time.”

He laughed, the deep sound filling the room. “You think so? Well, maybe they’ll have to knock out a wall or two. You know, make space for the new and improved me.”

The nurse called his name, and Brody stood up. The sight of his full height drew audible gasps from other patients. Ducking slightly to avoid hitting the ceiling, Brody walked to the examination room, his presence dominating the narrow hallway.

Inside the room, Dr. Harrison greeted him with the same clipboard and pen as last time, though his expression betrayed a mixture of shock and curiosity.

“Brody,” he said, looking him up and down. “I... barely recognise you.”

Brody gave a cheeky grin, flexing his pecs through the tight compression top. “Yeah, Doc, it’s been a busy couple of weeks. I think you’re gonna need some bigger measuring tools.”

Dr. Harrison chuckled nervously. “Let’s start with your height and weight. Step over to the wall, please.”

Brody straightened to his full height, his head nearly brushing the ceiling. The stadiometer, already extended to its maximum setting, barely accommodated him. Dr. Harrison adjusted it with care, standing on tiptoe to take the reading. His brow furrowed as he jotted something down, glancing at Brody in disbelief.

“Well,” he said, lowering the stadiometer, “you’re now exactly 8 feet tall.”

Brody’s eyes widened, his grin shifting into something between astonishment and exhilaration. “Eight feet?” he repeated, his voice booming with amazement. He took a step back, glancing down at himself as if trying to process it. “No wonder everything feels so damn small!”

Dr. Harrison nodded, a nervous chuckle escaping him. “Let’s check your weight next.”

Brody stepped onto the scale, the surface creaking slightly beneath his massive frame. The machine beeped as the numbers climbed rapidly, eventually settling. Dr. Harrison leaned forward to double-check, his pen hesitating over the clipboard.

“Four hundred and eighty pounds,” he said, his tone measured but clearly astonished.

“Four-eighty?” Brody echoed, his grin returning. He flexed his arms instinctively, watching the massive peaks swell. “Damn, Doc. I’m not just big—I’m huge!” He glanced back at the scale, shaking his head in disbelief. “Eight feet tall and pushing 500 pounds... I’m like a freaking freight train.”

Dr. Harrison managed a nervous smile, jotting down the numbers. “You’re certainly... unprecedented, Brody.”

“Unprecedented?” Brody said, laughing as he turned to admire his reflection in the room’s mirror. “Try unstoppable.” He bounced his pecs through the tight compression top, the motion making the fabric creak under the strain. “I’m not done yet, Doc. Imagine where I’ll be next time.”

Dr. Harrison cleared his throat “Okay, Brody,” he said after a moment, his tone neutral but measured. “Take a seat on the examination table, and let’s have a closer look.”

Brody climbed onto the table, which groaned loudly under his weight. The sight made him chuckle. “You sure this thing’s rated for me, Doc?”

Dr. Harrison’s pen hovered over his clipboard, his expression tightening as he made more notes. Dr. Harrison gestured for him to remove his compression top.

Brody pulled it off, revealing his enormous upper body. His pecs looked impossibly full, each striation standing out with definition. His abs were carved into six perfect blocks, their symmetry interrupted only by the faint sheen of sweat from the heat of his body. His nipples, slightly larger than before, stood out against the dense muscle of his chest.

“And your shorts, please,” Dr. Harrison added.

Brody smirked, slipping off his shorts and leaving himself in just his boxers, which strained against his growing glutes and the heavy bulge in front. The waistband struggled to stay in place, and the fabric barely covered what it needed to.

“Yeah,” Brody said, adjusting the waistband slightly. “I think these are about ready to give up.”

Dr. Harrison ignored the comment, though his expression betrayed his amazement. He called in several other doctors, who entered the room one by one, their faces filled with disbelief as they examined Brody.

“Look at the size of his arms.”

“Have you ever seen muscle development like this?”

“Even his body hair growth is outpacing normal levels.”

One blonde nurse approached to measure Brody’s biceps. She hesitated for a moment before wrapping the tape around his arm, her hands trembling slightly.

“Thirty-eight inches,” she announced softly, her voice filled with awe.

“Thirty-eight, huh?” Brody said, flexing slightly to make the tape strain. “Not bad. I wonder what they’ll be next time.” In his head he knew 38 inches was roughly 3 feet. The fact his arms were now several feet around filled him with a child like awe.

The nurse flushed, stepping back quickly as Brody leaned against the examination table, his massive chest rising and falling with steady breaths.

After a round of X-rays, blood tests, and scans, Dr. Harrison gathered the group to deliver his findings. “Brody,” he began, “your growth isn’t slowing down. If anything, it’s accelerating. This is unprecedented—your weight, height, muscle mass... all of it.”

Liz and Tom exchanged worried glances, but Brody only smiled. “So what you’re saying is... I’m still getting bigger?”

Dr. Harrison nodded. “Yes, and at this rate... there’s no telling where it will stop.”

Brody’s grin widened. “Sounds good to me.”

Liz cut in, her voice tinged with concern. “But what about the risks, Dr. Harrison? I mean, this kind of growth... is it safe? Shouldn’t there be negative symptoms by now?”

Tom chimed in. “Exactly. Gigantism usually comes with complications—joint strain, heart issues, headaches... But Brody seems perfectly fine.”

Dr. Harrison sighed, glancing over his notes. “That’s what’s so remarkable. None of the usual symptoms of gigantism are present. Brody’s heart rate, blood pressure, testosterone, and other vitals are all within a healthy range—better than average, in fact. But his rate of growth is unheard of. We’ll need to run a deeper analysis.” He drew a syringe to take brody’s blood before speaking again.

“We’ll call you with the results in the next day or so. For now, all I can say is to monitor him closely. If he experiences any sudden fatigue, dizziness, or pain, contact me immediately.”

Liz nodded, though her worry lingered. “Thank you, Doctor.”

The drive home from the appointment was quiet, the air heavy with unspoken worries. Liz kept stealing glances at Brody in the rearview mirror, her brow furrowed as if trying to piece together the right words.

“Brody,” she finally said, her voice soft, “you know we’re proud of you, right? But... all this growth, it’s happening so fast. Too fast. What if there’s something wrong?”

Brody rolled his eyes, leaning back against the seat with a grin. “Mum, come on. I feel great—better than ever. Whatever’s happening, it’s working for me.”

“That’s not what I mean,” she replied, her voice cracking slightly. “I mean... your body wasn’t made for this. What if it can’t keep up? You’re already... already so—” She stopped herself, as though saying it aloud would make her fears real.

“Enormous?” Brody finished for her, his tone light. “It’s fine, Mum. Really.”

Tom, sitting in the passenger seat, glanced back at his son. “She’s just worried, Brody. And honestly, so am I. We don’t know where this is going. Neither does Dr. Harrison.”

Brody stretched his arms behind his head, his biceps flexing with the motion, the muscles pressing against the car door. “You heard the doc, though. Everything’s normal. Better than normal. My heart, my blood pressure—all perfect. No symptoms of anything bad.” He grinned placing his huge hand on the back of her headrest. “I think I’m handling this better than anyone expected.”

Liz sighed but didn’t respond. When they pulled into the driveway, Brody hopped out of the car, eager to shake off the tension. Watching him stride toward the garage, Liz exchanged a worried glance with Tom. “We’ve got to keep an eye on him,” she whispered. “He’s acting like nothing can stop him... and what if he’s right?”

Back at home, Brody’s energy was at an all-time high. Still fired up from the appointment, he changed into his grey tank top and black shorts and headed to the garage. The tank top hugged every inch of his massive chest and shoulders, the fabric clinging so tightly it seemed one flex might tear it apart. His black shorts strained against his powerful thighs, barely managing to contain the sheer girth of his quads.

Standing in front of the mirror, Brody admired his reflection, his pride swelling as he ran a hand over his pecs. The meaty slabs of muscle felt rock-solid under his palm, flexing slightly with even the smallest movement.

“Damn,” he said, smirking as he traced his fingers down the striations of his chest. “These things are insane now.”

He turned slightly, running his hands over his broad shoulders and thick arms. Each vein popped out prominently, feeding the bulging muscle that now seemed to define him.

Moving to the bench press, Brody decided to push for a new personal best. He loaded up the bar with 650 pounds, an immense weight that made even him pause for a moment. “All right, big guy,” he muttered to himself, gripping the bar tightly. “Time to see what you’re made of.”

With every repetition, his chest swelled and his pecs rose dramatically, the thick slabs flexing and stretching with each press. His biceps and triceps worked in harmony, the motion smooth and controlled.

“Five... six... seven...” he counted aloud, his voice steady despite the immense weight. By the time he reached ten reps, the burn in his chest and arms was intense, but it only fueled his determination further. With a loud exhale, Brody racked the bar and sat up, a triumphant grin spreading across his face.

“Six-fifty!” he said loudly, glancing back at the loaded bar. “New PB. Hell yeah.”

Sitting up, Brody flexed his arms in the mirror, grinning at the sight of his veiny, massive biceps. “Man, my arms now are bigger than my entire chest used to be,” he said, laughing softly as he compared his current size to the scrawny boy he’d been just weeks ago.

The grey tank top, now drenched with sweat, clung tightly to Brody’s skin, the fabric tracing every ridge and valley of his powerful torso. With a swift motion, he peeled it off, exposing the full expanse of his chest and shoulders. The muscles gleamed under the soft light, thick and striated, each movement causing subtle ripples across his skin.

Kicking off his shorts next, Brody stood completely naked in front of the mirror, his reflection a towering testament to his transformation. His cock, even soft, rested heavily against his thigh, its size an unmistakable reminder of the changes coursing through him. As it stirred to life, Brody traced a hand down his chiseled abs, pausing to savour the tight, unyielding ridges before sliding back up to his pecs, which flexed instinctively under his touch.

“Not even human anymore,” he murmured, his voice thick with satisfaction. He bounced his pecs with a casual flex, the heavy slabs responding with perfect control, and his grin widened as he admired his reflection.

Sitting back on the bench, Brody let his hands wander lower, gripping his cock as it began to harden. The sheer size and weight of it filled his hands, the length thickening with every slow, deliberate stroke. The veins coursing along its surface pulsed visibly, feeding its growing girth.

“Bet no one’s ever seen anything like this,” he said softly, a grin curling his lips. By the time he was fully erect, his cock stood massive and unyielding, throbbing with a life of its own. Brody leaned back slightly, marvelling at its size and power, a grin tugging at the corner of his lips. He ran his free hand over his pecs, kneading the dense, unrelenting muscle as his arousal built.

“Fuck...” he groaned, the deep timbre of his voice reverberating in the empty garage. His muscles flexed involuntarily, the reflection of his powerful frame spurring him further. His breathing grew heavier, each exhale a mix of pleasure and exertion as he edged closer.

His grip tightened as his strokes quickened. Every pump made his muscles flex involuntarily, the veins along his arms and chest swelling with each rhythmic movement. His cock now stood fully erect, a towering, throbbing testament to his transformation.

“You’re unstoppable,” he whispered, his voice laced with pride and hunger. “Bigger than anyone... stronger than anyone. And this—” His hand squeezed his cock, feeling its incredible girth. “—this is just the beginning.”

“Fuck... look at me,” he groaned, his tone a mix of amazement and desire. His strokes became frantic, his body flexing and tensing with the effort. The memory of the nurse’s awe, the way her hands had trembled as she measured him, flashed through his mind. He imagined her staring now, unable to comprehend the sheer size of him, her shock feeding his arousal.

When the climax came, it was explosive. The climax surged through him like a lightning strike, every muscle flexing in unison. His deep, guttural moan filled the room, echoing off the walls as his cock exploded!

Brody’s entire body tensed, every muscle locking in place as he released, the sensation so intense it left his thighs trembling and his chest heaving. He leaned forward, forearms resting on his thighs as he caught his breath, his reflection still commanding his attention. A slow, self-assured grin spread across his face. “Bigger and better every day,” he murmured, his voice steady with conviction.

Rising to his feet, he grabbed a towel and wiped himself down, his pecs and arms still pulsing slightly from the pump. As he admired the way the muscles seemed to swell with life, he smirked. “Let’s see how much more I can push tomorrow,” he muttered, his grin widening as he considered the endless possibilities.
