Puberty Kicks In

added by vnixon 2 years ago AP BM S Muscle Hairy

Starting that day, the kid wanted nothing more than to show Jake what a mistake it was to ruin his life. But first, he'd need to get his mobility back. Nothing illustrated this point more than the fact that he couldn't lift his hips off the bed when he was on his back. Try as he might, gritting his teeth with effort, he couldn't get up: his massive, overgrown cock and balls had just gotten too big, too unwieldly. But, that gave him an idea.

He remembered how the beast Jake had turned into roared in that video when he squeezed his own balls. Testosterone fueled his power. And if his were big, well, the kid's were even bigger. Taking his slender, dainty fingers, he grasped at each of the grotesquely overendowed testes in his ballsack, each filled to the brim with an near unending supply of sperm. His fingers could barely encircle even a portion of the surface of those balls. Slowly, he began to knead at the skin, then more insistently as he felt the pleasure spread through his skinny body. He groaned lewdly, his back curling, his eyes shut in pure ecstasy. When, he opened them, he was surprised -- his ass wasn't touching the bed!

"Hell yeah," he whispered before the crushing weight of his expanding package sent him crashing down onto the bed again. He tried a couple more times, his legs and hips feeling like jelly. But all he needed to do was to give his massive balls a big squeeze and it felt like a herd of bulls were stampeding through his veins!

That night, he begged his mom for seconds, then thirds of dinner, his body eager for more nourishment to fuel it. He even asked for her to leave more food for him in the morning.

The next day, he tried again, eating the extra sandwiches his mom had left for him. To his delight, he found that he was able to get his hips up off the bed much easier. And after giving his full, sloshing nuts a hearty squeeze, he erupted, oozing white semen all over his emaciated, thin body like he did every morning, only this time, he had his feet planted on his bed and his lower back off it.

That orgasm sent him into overdrive. Soon, he managed to swing his legs over to the side of the bed. He gulped as he crossed the Rubicon and let his titanic nuts roll off the bed. There was no going back now. If he didn't get stronger, he'd never be able to get himself back on the bed if something were to happen. He gasped as his heavy, bloated scrotum smashed into the floor and he felt the pulse of testosterone course into his veins. All doubt left him and he he just knew he'd be able to do his 'workout.'

The boy was creative, he used his massive balls as weights. At first, he struggled to stand up from his seated position on the side of his bed. Groaning and grunting, he tried his hardest to stand, his weak, atrophied quads unable to produce enough power to do so. Not until he used his feet to press against his nuts against the floor, his body reinvigorated with a flood of male hormones entering his body.

Everyday, he'd beg his mom to make him more food. Everyday, he'd add new, creative exercises to his routine. He'd sit over the edge of his bed and pull his balls upwards in a makeshift bentover row to strengthen his back, grunting with pleasure as he not only squeezed his back at the top, but his huge nuts as well. He'd do tricep dips, resting his giant stones on his lap to add weight. He'd do anything to get stronger.

By the end of the week, his parents were in the kitchen eating dinner when they heard the trudge of what sounded like footsteps. Worried for their son, the kid's dad got up, thinking there must be an intruder. His jaw went slack when he saw the rail-thin body of his son slowly, methodically making his way down the stairs, his skinny body bracing the wall and both hands on the railing.

Leading the way was the kid's enormous fleshtube, but it didn't bother the dad, after all, it wasn't something him or his wife hadn't seen, especially since they often had to clean up after the boy. Rather than be mortified by the boy's indecency, the dad was overjoyed. His kid hadn't been mobile in years, ever since his cock had literally taken over his life. Embraced in a hug, the kid could feel the pride emanating from his parents, causing him to stiffen up. The moment was ruined when the weight of his erect 56" monster pulled at him so much that he fell forward onto the ground, the force enough to cause him to spill his seed all over the foyer.

Vowing to not let that happen again, the kid knew he had to get stronger still. His dad brought up the old weight set from the basement and set it up in his room. He even showed his son some basic movements, to which the kid took to. From the moment he woke up, he'd work out as he worked on his morning wood, often cumming hands-free as he massaged his tender balls between sets. Each time he did, he felt the jolt of testosterone being injected into him.

By the end of the month, his parents were beaming with pride as he had started joining them at the dinner table. He had to sit at the far end opposite to his parents, often because he could get an erection at any moment. He looked like a wiry, athletic boy appropriate for his age. His parents were overjoyed that he was finally 'catching up' to boys his age. Little did they know how far he was willing to take it.

He worked out harder, soon working his way up to needing his dad to order new plates for the equipment in his room. After another month, he was starting to look like a beefy high school wrestler, at least when he had a shirt on. With it off, he was lean and cut like a fitness model's. He was getting stronger and he reveled in it. When his parents were at work, he'd look at himself in the mirror, admiring the stubble on his strong jaw. He'd let his hands roam over his built body, his callused fingers running through the light dusting of body hair that now adorned his body, loving how they coalesced in the deepening grooves on his chest and stomach. And best of all was when his hands met at the base of his ever-growing cock, the monster now a whole inch longer than a couple months before. His constant coaxing of cum and hormones from his balls had sent his body development into overdrive. Hell, if anyone had to ask, they'd probably think he was a high school senior. And it led to his crowning achievement: as he stood in the mirror and flexed for himself, he could hold his erection in hand with confidence that it wouldn't topple him over.

He closed his eyes and groaned lewdly, basking in the overwhelming sensation of orgasm. Every nerve in his body was on fire, from his toes to his temples. Pure power flowed through him as he reached down and grasped at his gargantuan balls, sending his orgasm to further heights. He swore he could almost feel his whole body growing with the effort it took to keep his cock up and firing at the mirror!

His transformation into a muscled hunk only continued as he really began to lift heavier and heavier over the coming months. His changes were so rapid that one day his mother screamed when she came home to see a half-naked, stubbled and heavily muscled man in her kitchen, only to look south to see the heavy endowment attached to his groin leaking a profuse amount of pre-seed all over her kitchen floor. It was just her son looking like a college lifter.

His dad on the other hand was beside himself. He was finally getting the strapping, strong son he'd always wanted. The beefy kid inhaled all the supplements his dad bought, strained himself harder with all the new equipment he had set up for him in the basement, even building his boy a new room there so that he just needed to roll out of his now-king sized bed to get to 'work.' Not to mention, the drainage was much better down there.

Eat. Lift. Eat. Lift. Cum. The kid's mundane routine had completely transformed thanks to the power his massive endowment had given him. Now when he woke to his insistent morning wood, he marveled at how heavy his chest was, how the cool air of the basement brushed against his sensitive downturned nipples. All it took was a gentle squeeze and his megalith of a cock would stand at attention, reaching over halfway to the basement's ceiling.

It had been a year since his discovery of Jake's leaked private stream. The beastly 15 year old straddled the new bed his parents had gotten him, his feet dangling off the far end, the musclebound hunk having gotten too tall for it. Puberty had treated him well, gifting him with extra inches all around, shooting him up to 6'6".

Thinking he'd mark the anniversary of his apotheosis with a quick wank, he took his old laptop and propped it against the hairy cliff of his expansive chest, rumbling as his chest hair scratched against his dense beard as he struggled to peer down, his vision swallowed up mostly by his titantic pec shelf. He struggled to get his callused, thick fingers to hit the right keys, but he found what he was looking for. Just as he suspected, there was a new video that got leaked from Jake's private streams, and just his luck, it was from just the other week.

His hands went down to stroke at his massive tool, feeling it thicken as blood flooded into his lengthening rod. His hands worked slowly as he watched a now even bigger Jake slowly worship a year's worth of growth for the most hung, powerful bodybuilder on the planet. Jake's hands danced around pecs that casted heavy shadows onto his tight 10-pack, his serrati completed the look on his powerful torso. The big college-aged beast of a man brought his bloated, oiled arm up and gave it a flex.

"That's what a 30" bicep on a 6'4" giant looks like, boys," Jake rumbled his voice having gotten even deeper. The kid's eyes lit up. Did he just say his arms were 30"? He tensed his own arms and brought one hand up around his titanic chest so that he could see his arm. His dad had proudly measured his giant arms last night and the tape measure read 31"! Could he really have bigger arms than Jake?! That sent a jolt through his crotch and dick grew even stiffer to a mighty 58".

"Mmmf, yeah, it's rock hard, you little boys. My big cock and balls keep making me bigger." Big Jake grunted as he stroked his cock and gave his balls a good squeeze. "Oooh, it feels like I'm constantly GROOOWING," he moaned. He really got into it, massaging himself and yanking at his dick and balls even harder. "I'm already, ughhhh, 460 pounds, the biggest fuckin' MAN on the planet!" The kid was stroking himself harder too now. 460 pounds? That was it, that was what he was trying to beat?! He'd done that ages ago. He hit 600 pounds last night. Even accounting for what must've been 100 pounds of dick and balls, he was already bigger, stronger, more powerful than Jake! The thought that he'd achieved what he'd wanted in just a year made his dick grow even harder, pushing out of his crotch another inch.

"Oooooh, and this DICK... Aw fuck, you little boys and your dicklets can't even imagine what it must be like to be my size... and have your dick STILL growing! Ooooh, yes!" Jake roared as his self-pleasure was brought to a fever-pitch. "I've got a 20" cock and there's no signs that it'll stop getting even bigger!" The kid tilted his head back, enjoying the way the sinewy strands of his head-flanking traps brushed up against his ears. He was grinning from ear to ear now. If Jake thought 20" was big, then how about 60"?! He stroked himself faster and faster, his cock now painfully hard...

Oh fuck, but why stop there?! The kid felt his whole body spasm. He was bigger than Jake in every way. Stroke. Stroke. Stroke. He could feel the tension building, new strands of muscle fibers forming as he flexed harder and harder. He screamed as his bones cracked and as the blood forced his cock even larger.

"I'm a fucking GOD!" he bellowed, shaking the empty house.
