He's Got Potential, ch. 4 (Patreon)

Kaleb braced himself when the doorknob turned, the quiet rattle shattering the silence like a gunshot.  It was the moment he’d been dreading.  He’d wanted to run, but the instructions from Daniels made it clear he was to stay put.  There was still more they needed to learn, the message had read, and if he ran they were going to come after Tom as punishment anyway.  And, as much as it pained him to accept, Kaleb knew he didn’t actually have many other options since none of his or Tom’s clothes came anywhere close to fitting him anymore.  

In the few hours since lumbering from the chaos of the locker room he’d continued to grow, piling on bulky muscle at an impossible pace.  He’d stood frozen in front of the mirror, watching himself inflate like a balloon in slow motion.  His body puffed and expanded, his chest growing plump and heavy between a pair of shoulders that had officially swallowed most of his neck.  He was developing the kind of torso that guys would spend years trying to build in a gym, but all Kaleb felt was humiliated as he watched his formerly flat, ripped abs push outwards in a round, wide muscle gut.  He kept turning to look at his profile, trying to suck the solid beach ball in and make it as flat as he could.  It was a wasted effort.  There was no hiding the protruding stomach anymore than there was the large, round globes that counterbalanced it where his small, perky bubble should have been.  Nor was there any way to conceal his tree-trunk thighs or the nearly foot-long girder that throbbed out from between them.  

Kaleb knew exactly what was going to happen when Tom walked through the door.  He’d been able, barely, to run from the swim team, but he didn’t think he’d be able to control himself for long in front of his roommate.  Just thinking the other man’s name brought an avalanche of memories.  Every time Kaleb had seen Tom’s athletic frame naked after a shower, or lounging in his underwear, raced through his mind until his cock started oozing like a broken watermane.  Kaleb was well aware of how far he’d fallen, how when all this started he’d wanted nothing more than to spare his friend from being involved, but how now all he wanted was to feel the handsome jock’s smooth skin against his widened paws.  After what happened with his teammates Kaleb had a good idea of how things would end for Tom; he just couldn’t do anything about it.  He bit back a whimper when the door swung open, his mouth already watering.  

“Whoa!”  Tom jumped, startled by the naked hulk sitting in the dark on Kaleb’s bed.  “Jesus, dude, you scared the fuck outta me.  Can I help you with something?  I think you might be lost,” he laughed awkwardly.  “Little early to start...drinking…bud...” his laughter died off, his voice catching in his throat as his eyes adjusted to the dim light.  “Ka...Kaleb?  Is that you?”  The wall of muscle slowly lifted his head, revealing a face that, though bearded and fuller, unmistakably belonged to his roommate.  

“I think?  I don’t really know anymore,” the large man rumbled, his deep voice echoing off the walls.  

Tom gasped and took an instinctive step back when his impossibly inflated friend lurched upright.  Kaleb didn’t appear much taller, but the formerly lean swimmer was at least twice as broad, if not moreso, and covered in a dense layer of hair from head to toe.  He’d thought Kaleb looked hairier than normal earlier, but at least then he’d been the right size.  

The two of them should have been evenly sized, with similarly smooth, athletic builds, not a mismatched pair with one of them looming over the other like a hairy mountain.   Yet, somehow, Kaleb had gone from tight and tapering to a lumpy, beefy hulk who could have picked Tom up and swallowed him whole.  Even more shocking, though, was the thick, rigid club that jutted out beneath the other man’s newly protruding gut like a third arm.  He’d seen Kaleb naked enough to understand how his friend was so comfortable walking around in nothing but a speedo, but he didn’t think it was possible for anyone to be endowed with the kind of equipment he saw leaking onto the floor of their room.  

Tom blushed as his eyes locked on the bobbing monster between Kaleb’s meaty new thighs.  

“How did...I mean...what the fuck happened to you, man?”  

“You wouldn’t believe me if I told you,” Kaleb said, one hand running through the carpet on his slab of a chest while the other rested on his expanded stomach.  Still embarrassed by its size, he instinctively tried to suck it in while Tom stared in open-mouthed shock.  

“Are you okay?  Does it...hurt?”  Tom felt like he should be asking more questions, or at least be doing something other than gawking at his now-massive roommate, but he was having a hard time getting his thoughts to gel.  It wasn’t just Kaleb’s impossible expansion.  He’d seen powerlifters at the gym, and he was friends with guys on the university’s football team who were large in their own right, but he’d never seen anyone built like Kaleb.  When he moved, the other man’s hairy biceps inflated to the size of Tom’s head, and his thighs were practically as big as the stunned brunette’s waist.  “I just saw you earlier when you were getting ready for practice.  How could you possibly...wait...does this have anything to do with the rumors about the swim team getting sick?  I heard some crazy shit went down in the locker room.”  

“You could say that,” Kaleb grunted.  He rolled his head on his missing neck and shrugged his bowling ball shoulders, his plump pecs rising and falling rapidly as Tom stepped close.  “Don’t get too close...I don’t think I can help it…” 

“What?  Are you like, contagious or something?”  Ignoring Kaleb’s warning, Tom stepped within arm’s reach, putting a tentative hand against his friend’s furry torso.  Despite the rounded appearance and extra bulk, the flesh underneath the curly forest was like granite.  “Shit man, you’re jacked under all that hair, aren’t you?” he said, a distant look falling over his eyes as his hand squeezed the solid mound.  

“NNnn...Tom...I’m...sorruuunnnnNNNNN!”  Tom heard Kaleb grunting, but he was too focused on the volcanic eruption splashing against him to pay attention to what was being said.  The warm, sticky fluid soaked through his thin t-shirt and coated his arms, splashing up against his face and into his shocked, open mouth.  

“Is this...did you just cum all over me?” Tom sputtered.  He had no doubt what it was, but like the other man’s size, the amount seemed impossible, as did the force with which the bursts slammed into him.  He staggered back, squirming and pawing at himself when he felt the fluid not just begin to dry, but to seemingly leech into his skin.  Staring at his coated arms, he could see it vanishing, not hardening into the sticky residue like it normally did.  He should have been disgusted, but instead he gave a short laugh and stared back and forth between the naked beefcake and his soaked clothes.  “Okay...you really need to tellluuunnn...me whaaaaauugnnn...what’s...happuuunnn...happening…” 

Tom was confused by Kaleb’s sad look as the bigger man watched him squirm and tense.  “I tried to keep you out of it.  I really did.  But they wouldn’t let me leave,” Kaleb said, a pleading look on his face.  “If I did they were going to come anyway.  I’m sorry.”  

“For whaahhh...what?”  Tom followed Kaleb’s eyes to his lower half, surprised to find his shorts so soaked.  His friend’s eruption had hit his upper body, and he didn’t think enough had dripped down to make such a mess, though he quickly saw that he was correct when his spasming, solid cock unleashed another load in his shorts while he watched.  “Oh fuck...what the fuck was that…” he stammered drunkenly, pawing his fly open.  

Tom was still aware enough to know that he should have been embarrassed when his thick rod sprang free and returned the favor, spraying all over Kaleb’s hairy stomach.  He knew something strange and impossible was happening, that he should get out and go for help, but he was rooted in place as he writhed in front of the hirsute giant.  

Before Tom even realized he was stripping he had his shorts and underwear off and the sopping t-shirt pulled up over his shoulders, feeling like a child as he suddenly threw himself at Kaleb.  It was a reflex, an instinctive impulse that happened without conscious thought.  The smooth skin and sculpted muscle that he was normally so proud of seemed pitiful and feminine compared to his friend’s overwhelming masculinity.  He didn’t think of his handsome features and eager member as something to be proud of anymore, but as a source of shame.  He wasn’t a well-versed stud, but a boy pretending to be a man.  

The confusing thoughts flashed through his head in an instant.  By the time he’d stripped down and felt Kaleb’s soft, dense hair against his body there wasn’t room for anything other than the surge of desperate, aching lust.  

**********

“How...how we...doin’...?”  

“Don’t...don’t stop!  Fuuuuuckkkk…that feels...gooo...good…” Tom moaned, writhing in Kaleb’s bearish embrace.  His beefy friend was draped over his back, the soft layer of fur on the bigger man’s torso making him shiver as it pressed against him.  

Kaleb laced his fingers through the hair on Tom’s pecs and pulled the other man upright, loving the sight of his bulky torso and fat cock bouncing as he slammed into him.  “Whatever you...say…” he grunted, smiling at the loud moans pouring out of Tom’s ecstatic, slack-jawed mouth.  

Kaleb hated how much he was enjoying himself.  He knew he wasn’t truly to blame for anything that happened since he was just as much a victim in everything as Tom, but he still felt like he was taking advantage of the other man’s condition.  Like the swim team, as soon as Kaleb’s copious cum made contact Tom was driven wild, and like he’d predicted, Kaleb couldn’t help himself either.  When his friend had thrown himself at him that first night he was just as overcome, unable to do anything other than return Tom’s frenzied affection.   

However, unlike the swim team, more than Tom’s behavior was affected.  Like when he’d been injected, Kaleb started to notice the changes in his friend that first night.  When they’d finally managed to pull away from each other and Tom had collapsed in a spent, sticky heap on his bed, there were already prickly hairs starting to push up through his normally smooth skin.  The slumbering man’s changing body didn’t seem to mind the new addition as, like himself, Kaleb watched Tom’s now-insatiable cock spring to life while the other man slept, spraying out load after load of its own accord.  

Kaleb had sent a flurry of panicked messages to Daniels when Tom began changing, but his handler was as unhelpful as ever.  He told them to stay in the room and “ride it out,” saying that he’d be by to check on them “in a while.”  This was all part of the process, Daniels said.  They needed to see what exposure, specifically repeated exposure, to a mature batch of the formula did to someone, and Tom was a perfect candidate.  He wasn’t a genetic match the way Kaleb was, but if everything went according to plan the chiseled stud should undergo a similar metamorphosis.  Kaleb did his best not to think about how if things didn’t go according to plan, he’d potentially just turned his friend into a mindless, hairy cum factory.  

That concern grew when Tom woke up and immediately wanted to pick up where they’d left off, seemingly unbothered by his new look.  The formerly smooth man only grinned when he ran one hand over the soft fuzz coating his torso and wrapped the other around his widened cock, more concerned with getting those hands back on Kaleb’s body than with anything happening to his own.  

Tom was infatuated, constantly staring at his burly friend with wide, hungry eyes while they went at each other.  Even when he’d finally managed to take Kaleb’s massive organ in his tight, virgin rear, he kept looking back over his shoulder, his face a twisting mask of pain and ecstasy.  And as much as he hated to admit it, Kaleb was equally enthralled.  Where Tom seemed desperate to please, willing to do anything and everything, Kaleb felt a confusing sense of pride and ownership wash over him.  Watching Tom’s perky little rear sprout its own wiry coating as it grew plump and round filled him with a kind of satisfaction he’d never felt before, and the feelings grew in time with his friend’s changing body.  

Kaleb quickly lost track of how long they were at it, unsure if it had been hours or days.  Though he had more lucid moments than Tom they were as brief as they were rare, and each one left him feeling like he was looking at a stranger.  Each thirsty guzzle or soaking shower brought a similar round of alterations to his quickly inflating friend.  The chocolate-haired hunk started with a patch of dusky brown fur on his pecs that gradually snaked its way over his vanishing abs before flowing down his thighs, only to reverse course and drift back up, covering Tom’s rear.  The fur didn’t grow in as thick or as dense on his roommate, but his carpeted pecs and forested thighs were a far cry from the smooth skin he used to have.  

The same went for his friend’s expanding muscle.  Like Kaleb’s formerly lean frame, Tom’s shredded definition was a thing of the past, replaced with the same firm, round bulk covering the former swimmer, and when the changes finally stopped, the pair was almost back to being as evenly matched as when they’d first met.  The stunned, giddy Tom was left looking like a miniature version of Kaleb, thick and beefy, though not as large overall, with a coating of hair that wasn’t as complete but was no less impressive.  And while Kaleb’s club of a cock still had Tom beat, the other man’s fattened, nine-inch pole was just as eager.  

Things were blurry after that.  Just as they were finally winding down after who knows how long, Kaleb remembered Daniels suddenly being in the musky, cum-covered room with them.  Then there was a pinch, followed by a hazy stream of disjointed images.  Kaleb saw his bulky, furry new body stretched out on a table while Tom was trussed up in similar fashion across from him.  He recognized the lab, but could only grasp snippets of what was being said.  He kept hearing the word “success” over and over, hoping for the best as the world went black around him.  

And then it was over.  In a replay of his original abduction, he and Tom woke up in a dorm that had gone from a biohazard to sparkling and spotless.  There were even piles of new, larger clothes neatly folded next to each of them.  A look at his phone told him four days had passed since he’d fled from the swim team, though how much of that had been spent fucking Tom’s brains out and how much was spent in a lab, he had no idea.  

Tom didn’t remember anything.  His friend was understandably horrified when he awoke to find his smooth, sculpted body replaced by something bulky and furry, but he seemed to settle with an unnatural speed.  At first Kaleb just thought it was shock, but in the days that followed he noticed Tom’s whole demeanor had changed.  He wasn’t the drooling, cumming idiot Kaleb feared, but he was significantly more laid back, seeming content with whatever happened as long as he was near his hulking roommate.  And while Kaleb was still humiliated at the way his body, and gut in particular, strained against all of his clothing, his hair tufting out from underneath, Tom would cheerfully march down the hall in nothing but a tented jock.  His friend’s grades took a hit, but whether this was due to a change in his brain power or just an increased focus on his new interests Kaleb didn’t know, and Tom couldn’t have cared less.    

Of course people noticed the changes, but to Kaleb’s surprise they were almost as quick as Tom to adapt.  Everyone simply came up with their own explanation.  They were a pair of young jocks, so the going theories of steroids and growth hormones, or a late surge of puberty, weren’t a stretch for most people to accept.  And after the changes to the swim team became increasingly apparent, a pair of beefy guys were hardly the most exciting news on campus.   

Rumors about the coach were the first to spread.  He’d quit his job, but the middle-aged stud apparently hadn’t gone far as he was spotted stripping at a local bar, and it wasn’t long before pictures of the coach’s former swimmers following suit began to surface.  The ones who hadn’t dropped out quit the team, though they were still frequently seen wearing nothing but their speedos as they sauntered across campus, hopping from the bed of one confused jock to the other.  They had an allure over even the straightest of men, a power they wielded with wild abandon.  In the weeks that followed, Kaleb had both seen, and taken advantage of, the ripple effect as a growing crowd of confused young men sought to quell their strange new urges.  For the ones fortunate enough to make their way into his bed, there was no going back.  Unless they came returned for repeat visits they weren’t changed like Tom, but it didn’t take long before other big, hairy guys started showing up all over campus.  

Kaleb still heard from Daniels on occasion.  The mysterious agent wouldn’t divulge if the experiment had truly worked or what the ultimate goals were, but he made it clear they’d always be watching.  If Tom or Kaleb tried to go public with what they knew it would almost certainly end with them strapped to a milking machine.  Or worse.  

“Oh fuck...oh fuck...oh fuck…” Tom’s whimpering pulled Kaleb’s attention back to the present.  His friend was bouncing and squirming in his grip, his beefy frame bucking in time with the pounding he received.  “Gonna...cum...gonna cum…” he grunted, his full cheeks puffing as he heaved for breath and tried to hold back.  It was a futile effort.  With a final moan Tom tensed and froze, his inflated cock nearly punching a hole in the plaster with the force of his release.  He gasped and shuddered while the massive organ unleashed its torrent before pulling off of Kaleb and stretching out on their joined beds as soon as the endless flow began to ebb.  “Come on...give it to me…” he panted excitedly.  

Kaleb didn’t say anything as he grabbed his thick pole and started pumping furiously.  He unloaded all over his prone friend second later, wondering if the former lady’s man ever pictured himself gleefully smearing another man’s cum all over his hairy body.  He still felt a twinge of guilt every time, but Tom absolutely loved it.  

“That...what you...wanted…” Kaleb gasped, shaking his head and grinning down at Tom.  

“It’s just so good,” Tom sighed, running his hands along his slick, matted gut.  “And your face is real cute when you cum.”  

Kaleb felt his face go red beneath his beard as he draped himself over Tom, their hairy torsos mingling.  “Says the screamer,” he laughed, mimicking Tom’s desperate whimpering until the other man cut him off with a deep, forceful kiss.  He returned the gesture, their heavy bodies making the bed frames strain and squeak as they writhed together.  

Kaleb still didn’t know if Daniels had been telling him the truth when he said a body like this was always in his future.  He didn’t know what to believe when it came to anything the ominous agent said, but Kaleb knew what he felt.  He was still far from accepting of his new look and the future that had been forced on him.  He’d never have chosen such a fate willingly, nor would he have inflicted it on people the way he’d been used and forced to do so.  But with Tom’s brawny body still feeling small in his giant arms, gazing up at him with longing eyes, Kaleb wasn’t so sure it was such a nightmare after all.
