When a scientist at a Genetech laboratory secretly doses his lab assistant with an experimental compound, life will be anything but normal for either of them.


Turning Back the Clock Written by Leo_Todrius Commissioned by JR22

It had been another long day at Genetech, at least for John Ramis, He had been lucky to be accepted as a lab assistant for the prestigious firm, but being a lab tech came with a lot of responsibility and even more grunt work. His days started at four in the morning, making sure equipment was set up and all the test tubes were cleaned... But while it was annoying to get up that early, John rather liked the quiet before the bustle, at the times the only face he would see was his reflection in the glass walls of the laboratory. He wasn't vain, he just liked the calm. Still, he wasn't bad looking either.

John Ramis was twenty two years old with an average build and short cropped brown hair. From time to time he would buzz it just to keep it out of the way of experiments, though it grew out at a fairly decent rate. While he was a fan of relaxed clothing, he wore the same black acid proof shoes, tan slacks, white shirt and white lab coat of all the other Genetech employees. Sometimes it was hard not to feel like just another cog in the machine, but John knew even if that was the case; it was a great machine to be part of. Genetech was on the breaking edge of science, looking into the human potential in every direction. Some experimented with where the genes were going, where as his team was researching where the humans had been. Dormant genes held the keys to fascinating abilities and resiliencies that had been lost by evolution... at least that was the theory.

In many ways Genetech was a glass and steel castle. Most of the laboratories were glass lined, allowing light to pass from one section to the next. Even the test tube holders were transparent, though a heavy plastic rather than glass. Liquids of countless colors and variations filled the racks, holding every attempt that the team had made... all but one. While John was busy cleaning up, Doctor Hugo Weaver stood outside of the lab at the coffee station. He had filled two mugs with hot water, tea bags and sugar... but in his hand he held what he considered to be his best triumph ever, G-320...

Doctor Weaver was fairly young and ambitious, only in his thirties. His hair was just as raven black as it had been as a young student. He'd lived his entire live in the spotlight of an academic achiever. He'd worked his way up through the ranks at Genetech in record time, just as he'd made it through high school and college early... only to come to a dead stop at the snail's pace of the testing process. Rats, sheep, apes, and then man... It was preposterous, especially given the fact that none of those animals had the genes he was targeting. All his life he had done what it took to get to the finish line ahead of everyone else... and he wasn't going to let bureaucratic policy hold him back.

Carefully, Hugo removed the rubber stopper from the top of the vial before he tipped the amber colored liquid in. It plunged into the tea cup, diluting into the water, blending into the color and the consistency. The doctor returned the vial to his pocket, tucking it out of sight before he lifted the glasses and returned to the lab. The doors rumbled open as Hugo approached, allowing him to enter without having to touch the door. John glanced up with a smile.

"Welcome back doctor. I made sure to realign the electron microscope and the genetic sequencer is running diagnostics." John said, hoping to please his superior. Hugo smiled gently, a rarity for him when dealing with Hugo. He had demanded only the best assistants and they had given him John... His background was acceptable, but it was far from exemplary... The experiment was the best way to make the young man useful.

"I thought you could use some tea after all your hard work here John, here, drink up." Hugo grinned. John's eyes sparkled with delight. He'd always felt a bit of a barrier when it came to relating to his boss. This was the first time he had been so approachable.

"Thank you very much Doctor Weaver." John said, accepting the glass. Hugo smiled, lifting his own to sip at it. John lifted his and took a drink, murmuring happily, "Chai, right?" he asked, hoping he got it right.

"Yes, I thought I would mix it up today." Hugo replied. In truth Hugo had guessed it would be the best flavor to mask the G-320's soft spicy flavor, or what he guessed the flavor to be based on the molecular structure. Whatever it was, John hadn't seemed to notice. Hugo watched John drink it with great interest. John took a gulp, then another, though he sipped it near the end. Hugo was more reserved in his drinking, his eyes not letting off of the lab tech. Finally, John sighed after draining the mug.

"Thank you again Doctor, that was really a nice way to end the day." John smiled. Hugo's eyes went wide in surprise.

"End... end the day? I thought you were scheduled for at least another hour..." Hugo said. John looked surprised before he glanced at the doctor's watch and realization dawned on him, shaking his head.

"Doctor, Daylight savings was last night. We sprung forward an hour... and normally I'd stay on after work, but I'm feeling really tired and I have another early start tomorrow." John replied. Hugo glanced up.

"Is your exhaustion a recent feeling, or has it been affecting you for a larger portion of the day?" Hugo asked clinically. John was a bit amused.

"It's just been a long day, it's been gradual. If anything, I think that tea picked me up just a bit. Anyhow, have a good evening doctor. I'll see you tomorrow." John said, moving to the door of the lab and then out into the hall. Hugo turned slowly to watch his lab assistant disappear. He had hoped to monitor him for at least an hour, but if it didn't work he would know by morning... Hugo just wondered how John would react.

****

The many locks to John's apartment clicked and shuddered before the thick door eased open. John hated living in such a crappy neighborhood but it was closer to work, the pay was good and the police were always close by. He just had to adjust to the sounds of sirens, shouting, and the occasional gunshot. Still, it wasn't all bad. He'd been fortunate enough to get a corner apartment in which no crime had been committed and it was still in pretty great shape. The wood floors were solid, the shelves were built into the wall and the building even had an old curved window in the corner. It was aged and hard to open, but it was such an architectural oddity that it gave the place quite a bit of charm.

John shut and locked the door behind him before setting his coat onto a hook on the wall, stretching and yawning a bit. He hated springing forward, it always made him feel late for things and it would likely keep him up past when he wanted to be asleep by, but at least he hadn't stayed at work longer. With luck that would give him enough of a cushion to make the transition, but first he would reward himself with a very nice shower. He'd get all the smells of the lab off of him before bed.

The young man moved into the hall stretching off left of the living room and into the small bathroom, turning on the hot water and pulling the stopper to shift the tub into shower mode. The shower head sputtered before the thick stream came out, though it would take a few moments to get hot enough. John used that time to move into his bathroom, sitting down on the edge of the bed to remove his shoes, his socks and then his slacks, tossing them all into the hamper. He pulled off his shirt as he stood, then stepped out of his underwear. John was just as well groomed below the waist as the head on his hair.

He padded across the carpet before stepping out onto the wood floor, heading back into the bathroom. He dipped his hand into the stream and nodded, glad the water was just reaching the ideal temperature. He stepped under the shower curtain rod without having to duck, letting the water splatter as it hit his chest, washing away the sweat of the day. John shuddered softly as the water pelted his skin. The shower head was old but it had a way of making the water just thick enough and strong enough to massage his skin.

John let the water pelt his front before turning, letting it cascade over his stiff muscles. He reached out one arm, bracing it against the wall. With so much time devoted to work, he hadn't had time to look for that special someone to massage him. The shower head was about the only love he ever got. The water streamed down over his shoulders and back, cascading over his ass cheeks and down his legs. It soaked him well before he turned, running his head under it, the water wetting his hair... but as he lifted his head out of the way, his hand reached to bring the shower head down.

The thick beads of water began to pelt John's cock, stimulating the shaft all over like a deep tissue massage. His eyes clenched shut as he moaned gently, the water stimulating him in excellent ways. It was part of John's regular routine to pleasure himself in the shower, but something felt different this time, something felt... better. The blood rushed into his groin, his cock lifting away from his body as it grew hard in record time. He grunted softly, a tingling filling his body. His cock continued to stretch, reaching its peak erection... and then slowly edging past it.

"Fuck..." John muttered in awe, never having felt so horny before. Blood continued pushing into his cock, causing the flesh to darken and become a reddish purple. He hissed in sensation, it felt so tight... But then suddenly the pressure ebbed a little as the cock found more room to stretch and grow. The shaft began stretching wider and thicker, even at the base. John had been fairly average before, but as his meat widened it was starting to look like a club, a thick and meaty club.

John panted softly, feeling his shaft tug at his groin, extending from him and receiving the water all over it. He felt like reaching out, grabbing it, working it... But at the same time it felt so heavy on its own, so powerful. John began to sway his hips, causing the thick shaft to sway up and down. As gravity took hold and pulled it down, it thwacked against his balls and began to grow more erect again. John suddenly leaned forward with both arms, holding himself up against the wall as the water sprayed all over his head and ran down his cheeks to drip from his chin. Still John thrust.

His cock ached with erection even as it grew longer to make up for the pressure, the flesh extending slowly. John didn't believe his senses, it had to be some sort of lust illusion, but it sure felt good enough to embrace... and finally he did embrace it. John reached down to wrap is hand around his cock, giving it a good squeeze before his hand slid along the length... and then slid a little more. John's eyes snapped open in confusion. He had jerked off countless times in his adult life. It had been the same since he was sixteen years old, but now... there seemed to be a little more to work with.

John's lips curled into a grin slowly. He knew he should have been shocked, should have been concerned... but for some reason the thoughts were draining out of his head. All he could think was that his cock felt good, and he wanted it to keep feeling good. John's eyes closed again and he began to stroke his shaft off with his right hand, his left still holding him up, his shoulders hunched as he leaned forward. His hand slipped up and down the shaft eagerly and soon his hips were thrusting, trying to help out. Each thrust of his hips was like lightning, energizing his system. He felt stronger, more virile... and then a grunt escaped his lips, and John rather liked the sound of the grunt, so he grunted again... and again, with every thrust he let out the beastly noise, his grin growing larger.

The water spilling over his hunched shoulders began to change course, shifting slightly as the muscles beneath his skin began to grow. Centimeters at a time, his shoulders expanded. The muscle thickened, the bones began to throb, even his spine was thickening just a bit. John was none the wiser, working on his cock, feeling it fill his hands so right. It had continued to stretch with each tug, pushing past a foot in length, thickening past the point of a beer bottle. Somewhere in the back of his mind he knew this was strange, but it was also so good. John loved the feeling... and the feeling was still growing.

John tugged at his cock, almost as if trying to extend it himself. He moaned loudly as he passed fourteen inches. He had no idea how long he would be soft, but he had no doubt it would be impressive... but then again all of him was impressive. John slowly stood upright, nearly hitting his head on the shower head, though his shoulders were still a bit hunched. He brought his other hand down to his groin and began to draw it over his shaft, using both hands to explore every contour of his member. He felt the veins, the flesh, the girth. He even ran his fingers around the base of his cock before trailing them through his bush.

"Ungh..." John moaned, his head tipping back. Normally his bush was quite well groomed, but it had grown out a bit, the wiry hair thick. He stroked through the hair almost as if petting it, the sensation sending a tingling into his balls. His fingers continued through the pelt to the edges, only to realize his bush was wider than before, spreading across his lap... and new hairs were growing out at the edges, pushing out and curling, growing thick. John panted a bit in surprise, but pride soon filled his heart. He was truly manly.

In his mind, worries about bills and jobs and debts and friends were fading away. All that mattered was pleasure and the pursuit of more of it. His hands continued to wander, finding his balls... His sack seemed bigger, his balls hanging lower... and as he fondled them, he could feel them growing bigger too. He shuddered, letting out another grunt as he fondled them, rolling them around in his hand, feeling how heavy they had gotten. The change was clearly progressing, but with his balls having swelled, new hormones were coursing through his body.

Unable to restrain himself, John soon wrapped both hands around his shaft and resumed working his shaft off, thrusting his hips forward and back. The water spiraled down his legs as the hair grew thicker and darker along them. His body was growing in many ways, but it would need to have new supports if the growth was to continue. In a natural response, John's feet began to throb before they swelled. The water streaming down the slope of the tub broke around his growing heels, casting a wider wake in front of his feet. His toes slipped forward, gripping onto the porcelain every few moments only to surge longer again.

The bones creaked and throbbed, growing thicker as new sheets of muscle washed over them. It was an odd sight to see his feet growing so quickly, or at least it would have been if he was paying attention. So fixated on his cock, John didn't notice his feet surpass size twelve, fourteen, even sixteen. The toes were so thick and long, but most of all... they were starting to become hairy. Soft brown hair began pushing out on the knuckles of his toes, then the top of his feet. It was patchy, but it was clear... and the same change was starting to affect his hands.

Again John grunted as his hands swelled, his fingers lengthening and thickening. His palms widened, taking up more of his shaft. It felt good, but at the same time it threatened his ability to jerk off with both hands. He looked down at how pudgy his fingers had gotten, watching hair grow out of his knuckles and the back of his hand. John grunted more in delight before he rubbed the back of his right hand across the head of his shaft, a thick string of precum connecting the two. He lifted his hand and ran his tongue over the flesh, feeling the thick flesh and the hair, tasting the salty bloom of musk on his tongue.

"Oh yeah, that's the stuff..." John moaned, though he froze in place as he heard his own voice. It wasn't just deeper, it was octaves deeper. John moaned more in surprise, feeling more turned on than ever. He knew he should go get help, to figure out what was happening. It was becoming clear that it wasn't just a dream, but on the other hand he didn't... want to. He was enjoying himself so much, he was proud of how he was starting to look. He didn't want it to end, not over worries about being normal... He wanted to see how far it would go...

John resumed working his shaft with his left hand, working it hard, panting and grunting as the changes continued. With his right hand he felt up his balls, then his abdomen. Beneath his fingers he felt his muscles forming into neat clusters before bulging outwards through the flesh, creating far more than a washboard. It was almost as if he had muscled plating. He fondled the edge of every muscle, caressing his front before he reached up to give his nipples a tweak, though he certainly had to find them through the forest of hair that was growing out across his chest. He eventually found the sausage of a nub, surprised by how thick it was.

"Mmm, yes." He growled, his voice deep enough to rattle the bathroom mirror. He tugged and twisted his nipple as he jerked off his cock, feeling his orgasm looming on the horizon. He wanted to make the pleasure last longer, but he couldn't slow down. All John could do was enjoy the pleasure in the time he had left. He continued exploring his body with his hand, feeling every change. His collar bones were thick, his shoulders were wide, his neck was immense... Everything was bigger and hairier than before, everything but his face. John reached up to see if anything had changed on his head, but a sudden aching filled his head, signaling that such a change was only starting.

John panted softly as the sensation grew, starting as an ache above his eyes. It felt like the worst headache of his life, but as the pain started to die back, the pressure only increased. The bones beneath his eyebrows began to swell, growing larger and thicker, pushing out over his eyes. His eyebrows started to grow longer and denser before new strands pushed out between the two, connecting them loosely. A strange, dangerous look crossed John's expression as his brows pushed out, almost as if he had grown more primal, as if nothing would hold him back... nothing but the pain.

Deeper grunts and moans of discomfort came as John's jaw began to widen, pushing out thicker, changing his facial features more... But even as his jaw changed, the hormones were catching up with him. John reached up to run his huge hands over his jaw, feeling the bones swell, but he also felt the rough scratch of stubble. Thick strands of hair pushed out over his cheeks, darkening them as it thickened. John grunted more and more, starting to pet his beard as it grew. His entire life he'd been unable to grow a beard because of work or parents or rules... But it felt good, it felt damn good.

The hair kept pushing out, the ends dulling, the strands growing longer. At first it came in as thick sideburns, then the chin filled in. Slowly a strip of hair appeared over his upper lip before curling over. His lips disappeared behind the curtain except when he growled in his pleasure, combing his fingers through his beard. It grew inches at a time, stretching out, softening just a bit. The beard was incredibly impressive at first with his short hair, appearing truly long... but as thick brown locks came sliding down into John's field of view, he realized that all of his hair was likely to blend a lot better soon.

The water soaked hair dropped down to his shoulders, his beard growing out almost all the way to his nipples, thickening steadily. Water beaded across the thick brown face pelt, leaving John to massage it in and feel how thick and luxurious it was. John panted hard, his heart racing, his cock throbbing. It felt exquisite in every sense of the word... but he had to see it. John backed up slowly until his back was touching the rear of the shower wall. He turned his head to glance at the mirror, taking a breath.

While the mirror had fogged over, it was still possible to see his vague outline... His mane of hair... his height... and his incredible muscles. John looked like a muscle builder, more than that... He looked like a cave man... And that was when it struck him. John figured it all out... Doctor Weaver, the tea, the 320... He'd been dosed; his past potential had been unlocked. It had been an illegal and immoral test, but it felt so good. John wasn't just a cave man; he was the best cave man, the most manly. John faced the mirror, stroking his beard with one hand while jacking off with the other. He tilted his head back and let out a deep moan before his cock spasmed and thick jets of cum arched across the bathroom, splattering against the mirror before dribbling down into the sink. John sprayed for what seemed like a full minute before he stumbled back into the stream of the water, panting as his chest heaved up and down... but a thick grin crossed his face.

****

The harsh buzz of an alarm clock woke John as he let out a deep grunt of dissatisfaction. One eye hazily opened to see that it was three a.m., the time of morning he had to get up to get to work. John grunted before he brought his fist down to hit the snooze, though as he felt the plastic crack and collapse beneath his fist he sat up slowly. It took John's brain a moment to remember the events of the last night. At first all he remembered was feeling fantastic... and cumming a lot... but then the rest started to come back. John tossed the blanket back, looking down at his body, gasping softly.

While he was no longer the caveman he had become last night, it certainly seemed that many attributes had clung to him. Before his cock had been a mere four inches soft if he was lucky, now his dormant snake was nine inches limp and as thick as the bottle of Tabasco that he usually put on his eggs. His bush was thicker, his leg hair was thicker... and his feet even seemed bigger. John reached up to run his hands over his cheeks, finding a short but dense beard, a bit more than stubble. It would be hard to explain that away at work... Maybe he could shave.

"Oh god, my hair..." John blurted before realizing his voice was still a bit deeper. He reached back, feeling the base of his brown hair. It reached all the way down to the nape of his neck, far longer than before. He slipped out of bed and moved out into the hall, then his bathroom, moving over to the mirror. He leaned in close, trying to get a really good look. The reflection was not one he was used to. His nose was a bit wider, his eyebrows a bit thicker... But if he cut his hair and shaved, it might be passable.

John reached for the drawer and opened it up, looking down at the scissors and trimmers for a long moment... but then he slowly slid the drawer shut. He felt odd, embarrassed... but at the same time he felt proud, he felt manly. If he removed those traits he would just be going back to his old life. If the caveman was a one time thing, he couldn't give up the lingering gifts. He wanted to embrace them. He would just have to learn how to adjust... But he'd have to figure out on the run or he would be late for work.

****

To say that it had been a strange day would have been an understatement. John had gone through the day hunched forward just a bit to try and hide the snake of a cock in his pants. It was longer soft than he had been hard. The downside to hunching was that it made him appear even more like a cave man... and his clothes didn't seem to help matters. His shirt was way too tight, the sleeves clinging to his biceps and triceps, his buttons digging in between his abs and pecs... and his shoes were killing him, feeling several times too small. He'd had to take them off at break time just to get a little relief, but that wasn't to say it had all been bad.

Most of his co-workers hadn't noticed how sudden his hair and beard had grown and had complimented him on it. John puffed up at the compliments, taking great pride in them. He'd also found himself inadvertently flexing around some of the staff, showing off his muscles even more. He'd flustered both male and female co-workers, sending chills of excitement through him... after which he would feel a bit embarrassed about being so physical, so primal. It was a hard balance to manage, but it was even harder when Doctor Weaver showed up.

John knew that Weaver had been watching him all day. How could he not? It was clear the substance had worked, but Weaver had no idea how much. John knew Hugo knew, but how far would he push things? Would Hugo ever try to dissect him? John kept a watchful eye on his employee, his fist always at the ready to club him down. Hugo, however, was oblivious to such a threat to his personal well being. He had the audacity to attempt to disguise his research in the guise of small talk.

"How did you sleep last night John? Good?" Hugo asked, casually running a scan on some of the 320 samples.

"Pretty good." John replied non-comitally.

"Anything interesting happen? Anything out of the ordinary? Some... show or something?" Hugo asked, biting his lip when he wondered if he had been too foreword. John turned away to grab a beaker, rolling his eyes. Even if he was a caveman, he still had some intelligence.

"Didn't catch any TV, showered and went to bed mostly." John replied. Hugo nodded, scratching down the notes on a piece of scratch paper.

"Your beard is coming in nice by the way... When did you start growing it?" Hugo asked. A shiver ran up John's spine. Hugo had stumbled across one of John's weaknesses.

"Pretty recently... But I really want to grow it out... as long as I can... Like a badge of masculinity." John said, almost moaning. The scribbling of the pen brought him back to reality and he winced, "But that isn't very professional regarding work... I know the bosses would never go for it." John sighed. It was Hugo's turn to be uncomfortable. Work policy was standing in the way of his experiment, contaminating his study.

"Well, it isn't like our samples are at high risk for contamination... Why don't you forget that policy for the time being. I'll have a word with the bosses. Too long have we been fettered by rules. Some of the greatest scientists ever let their grooming go whatever way it would. You should feel free to do the same." Hugo grinned. John turned, looking at the doctor for a moment. He knew it was a selfish move of the scientist, but at the same time... he wouldn't have to shave.

"Thanks doc." John said before he got back to work, taking his victories where he could. He still felt the sea of conflict in him. He'd been dosed against his will, but it still felt so good... John wasn't sure what to do about it, at least not yet.

****

Amber liquid poured into the glass pitcher sitting before John as white foam bubbled up to the top, cresting at the rim before the bartender moved off once again, amazed by John's stamina. John was fairly amazed himself. He'd barely ever had alcohol before and he had been a bit of a light weight, at least before the 320... Now he was on his second pitcher of beer and didn't really feel much of a difference. He'd hoped it would help him come to a decision about Weaver but no insights had appeared at the bottom of the mug and he doubted any would be at the bottom of the next.

What had kept John drinking, however, was a most incidental of side effects. The feel of the foam in his mustache and the tang of the beer seemed to exhilarate him. Feeling it slide down his throat, feeling the mighty heft of the pitcher in his hand, it fed right back into the feeling of primal masculinity that was feeding him. He tipped the pitcher back and started to gulp the beer down, feeling his cock grow firm and stretch out against the confines of his pants. It was a good feeling, one John relished... but all too soon the pitcher had been drained, the last of the golden drops flowing into his mouth and down his throat.

He knew he would have to deal with Weaver eventually, but he wasn't going to find his answers in a bar and he still had to walk home. John pulled out his wallet and put money down onto the bar before he stood up, returned his wallet to his pocket and moved for the door. He navigated through the thick number of patrons before moving out of the establishment. The door jangled to a shut behind him, then jangled back open as two men emerged, then a third. John continued walking, though he could hear their foot steps behind him.

John thought back to the bar, of the people near him. He thought of the table of skin heads that had downed a few already. He wondered if they had followed him out in the hopes that the beer had impaired him and made him sluggish. A glance to the store front window proved it was the men he was thinking of after all, garbed in their black leather with their shiny skulls and their thick goatees. Like the prey of a mighty beast, John's eyes surveyed the surroundings. They were approaching an alleyway between shops. That would be where they struck if he let them... A small smile crossed John's lips.

He knew he had the upper hand if they did, though he wasn't going to provoke anything. Perhaps it was a coincidence; perhaps his caveman instincts were paranoid. He would just have to see. As John approached the alley, it seemed that his instincts weren't far off. The footsteps behind him picked up before one of the men circled around in front of him, another moving to stand between John and the street. John came to a stop, not looking particular phased by being encircled. No doubt they assumed it was the beer. They couldn't have been more wrong.

"Let me pass." John said, looking to the man before him.

"Easy peasy bud, but you gotta pay the toll. Give us all the cash in your wallet." The thug grinned. John smirked.

"You do realize we're becoming a cashless society, right?" John asked.

"Very funny smart alec, but we know you paid in the bar." The thug behind John said.

"You're right, I did... So I don't see why I need to pay here." John said, moving to push past the skin head. They moved, shoving John into the alleyway. John spotted the arm coming out of the corner of his eye and tightened his abdomen. The fist hit the tightened muscle and shot back in pain.

"Fuck, man!" The skin head winced. Another thug went for John's head but he caught the hand and started to squeeze. The man yelped in pain before his legs started to grow weak. He reached to clutch at John's hand to try and free himself but was making little success. The other two tried to punch John, the first hitting his chest, his stomach, his arms, but none of it was working. One of the thugs took a swing, connecting with John's jaw. John's head turned to the side before he used his free hand to reach out and grab the man's neck, squeezing and lifting.

Slowly John hoisted the thug off the ground by his neck, forcing him to clutch at his throat, trying in vain to pry the fingers from him. They both dangled in fear from the man, true fear racing through their hearts where there had only been malice and pride before. John could feel the adrenaline coursing through his mind, knowing he had turned their bravery into cowardice. He was feeling fairly confident about himself until the glass beer bottle smashed across his head. John dropped the two men, stumbling further into the alleyway, his hair falling over his face. As he came to a stop and reached out to steady himself on the wall with one arm, he could taste the alkaline iron tang of his blood; feel the hot wet dripping down his cheek and into his beard.

Slowly John lifted his head, gazing through his curtain of hair at the three thugs. His chest rose with every breath, but it didn't shrink back down. His pecs and abs hardened, his ribs spread apart, his shoulders hunched. A deep, guttural growl began to pass from John's lips as they thickened, his nose widened and his eyebrows began pushing forward. His eyes disappeared into the shadow cast by the thick bone, though enough light reached them to make them almost glow, seeming more amber than brown.

"What the fuck?" One of the thugs muttered.

"It's a trick..." The other whispered.

"Come and try me, assholes..." John said, his voice deepening with every word. His hands thickened and widened, his shoes strained as the laces popped and the leather splayed, revealing the tops of his thick and hairy feet. As his shoulders spread wider and his chest thickened, the buttons on his shirt started to pop until they pulled apart, revealing the thick forest of brown hair on his chest, his very large chest. His arms throbbed, growing longer, his hands sliding down towards his knees.

Despite the fact he was trying to intimidate the thugs, the pleasure was becoming stronger in his body. His huge cock hardened, snaking down his legs, making enough of an outline to make some horses jealous at how well hung he was... but most of all, John's hair was growing. His beard pushed out of his face, his hair grew longer from his head. He was muscle, he was hair, he was male. John relished in the change before he turned to the side. At first the thugs weren't sure what John was doing until he grabbed a full garbage can with one hand, lifted it up and hurtled it. One thug took off running but the other two were so stunned that it caught them square in the shoulders, knocking both to the ground as the garbage spilled all over them.

They scrambled to get up, dripping with coffee grounds and banana peels. They glanced back only to see the hulking caveman moving toward them, his huge hands outstretched. The skinheads scrambled to their feet before running off, disappearing from sight. John grinned at his physical prowess, feeling the adrenaline rush through his veins. He moaned in delight before he reached down, running his palm all over his groin, groping his cock through his slacks. He panted hard, his eyes rolling into the back of his head. The pleasure throbbed and soon a wet spot formed in his pants.

John glanced around before noticing a partially out of sight spot behind a support column outside the building whose trash can he had stolen. John swaggered over, his posture far more ape like before he moved behind the column. He reached down to pop the button of his slacks and unzip, letting his thick cock slip free of the confines of his clothes. He had simply been too large to fit into his pants or shoes with any manner of undergarments or socks... but the only thing on John's mind was his huge shaft.

Once more his hands wrapped around his cock, squeezing tightly. He worked his shaft up and down, his hands gripping tighter and tighter, thrusting his hips into it. He grunted, bearing his thick teeth, the wind blowing through his thick head of hair and beard. John rolled his shoulders, getting a feel for how wide and thick they were. It truly was magnificent. John thought of how strong he had been, how scared they had been. He had bested three fully grown men, but that was because he was more than man, he was cave man, made of the rock of the earth.

Drool leaked out of the corner of John's thick lips as he jerked his cock off with all his might. Thoughts slowly drained from his head as he focused only on his cock. He worked himself off hard before he felt his massive balls seize up. John tipped his head back and let out a deep guttural moan, then a howl. His huge cock pulsed before thick jets of sperm launched from his shaft, showering all over the alley. Seconds passed, then a minute, then almost another half a minute passed before his load finally subsided. The constant rush of the muscles and the steady flow of cum saturated his brain with endorphins, leaving him drunk with pleasure and very satiated. Obscured in the shadows of the alley, the caveman fondly rubbed his cock, admiring how shiny the flesh was, the thick musky scent filling the alley.

John suddenly awoke, his eyes snapping open. He had been awoken by a deep rumbling sound, only to realize from the pressure at the back of his throat that he had been snoring. John stirred gently before he gasped in pleasure, feeling his beard brushing across his chest hair. He reached up to feel the hair flowing from his face, dropping down from his chin several inches to where the base tangled with the curls across his muscles. John growled happily, stroking his beard slowly, feeling his cock wake up from its slumber. The flesh snaked across his leg as it hardened, slowly lifting up the blanket into a tent. John sighed happily, trying to put together the memories of the night before.

It was harder to get to the memories than before, possibly because of the beer, but then he remembered; the skinheads, the thugs, his physical prowess. John grinned in pride, lifting one arm to flex it, watching the muscles bulge. He'd been such a man. John was very happy with himself until he realized that there was light coming from the windows, the sun was starting to rise... He was several hours late to work. John snapped his eyes to the clock, the clock he had crushed the morning before.

John grunted, deciding since he was already late that being a little more so wouldn't hurt him. He swung his legs out of bed, his feet sinking into the carpet. He slowly hoisted himself upwards, swaggering toward the door frame, ducking beneath it just a bit before he turned the corner and moved into the bathroom. John turned on the sink, cupped water in his hands before he brought them over his face. His fingers worked at the grime and sweat and blood, washing them off before he blinked and looked at his reflection.

More of the change had stuck around again. His eyebrows had grown together into a unibrow, his beard and hair were longer, his jaw was fuller, his nose was thicker, and he seemed to be a fair bit taller than before, by several inches. John looked down at his huge cock, his huge legs, and the rest of his huge body. He had been trying to debate how to go about everything with Weaver for days, but it was clear. He was clear. There was no hiding what he was anymore and he didn't want to. They couldn't punish him for what Hugo did, but John could confront him.

It was true in many ways John was glad that he had changed, he felt so amazing, so wonderful. He didn't want to punish Hugo for changing him, but he wanted to make sure he got justice. He needed a raise, a clothing allotment, a... steak stipend. John licked his lips as he thought of the delicious red meat dripping with juices as he bit into it... But then he brought his thoughts back to Hugo. If Hugo wanted to study him, fine, but it would be on his terms. John left the bathroom behind, moving to the closet. He opened it wide, looking for any clothes that would even remotely fit, policies be damned.

Hugo murmured softly as he watched the steaming hot stream of brown coffee spiral into his cup, sloshing and settling. He lifted up the tap and brought the cup to his lips, tipping it back. He could scarcely get a drop without burning his tongue but even that helped to wake him up a bit. He had been working up in his office through the night and into morning, catching an hour or two of sleep before returning back downstairs. He greatly regretted that he had missed daylight savings and an hour of study. He even debated going to John's home to break in and get samples while he was working, but perhaps their day of observation would give better results.

The doctor moved down the hall to the lab and pushed the door open, moving in towards his work station... and then he stopped in the middle of the room. He didn't see John anywhere. He looked to his left, then his right. As he studied the room, the door eased shut behind him and suddenly the glass walls polarized, shifting from clear to frosted white. Hugo spun around and let out a soft yelp when he saw the man standing by the switch.

John stood at seven feet tall with his hair down to his shoulders and a beard to his collar bone. His knuckles were hairy, his arms long, his muscles huge and his shoulders a bit slumped. It seemed like his teeth were a little too big for his mouth, pushing his lips foreword and his brow was thick, jutting over his eyes... But he wasn't fully caveman. Every change brought him closer permanently and it seemed he was very close indeed. With the windows polarized, none could see into the laboratory.

"John, what happened to you?" Hugo gasped. John snarled, striding over before he shoved the doctor, knocking him back into a chair that rolled into the cabinets. John lifted a large foot and set it on Hugo's chest, pinning him in place. Hugo wheezed as the air was knocked out of his lungs, first from the shove and then the foot. John held him trapped where he was, pinning him. The foot stretched all the way from his navel to his collar bone.

"You know exactly what happened to me, you gave me the G-320, you experimented on me without consent, without permission... You weren't authorissssed to do human trials for a year!" John shouted, though it seemed he had a hard time pronouncing z with his modified mouth. Hugo squirmed.

"John, I would never..." Hugo panted. John's thick brow lowered.

"You would never what? Bring me tea unless it was to your advantage? Do you even realize how hard I've worked for you? I did the chemical analysis to determine the most likely taste because the marketing department wanted to know. You knew what to hide it in because of me!" John growled. Hugo trembled a bit before his eyes widened.

"But... but it worked John, look at you... You've got your mind still, but you've got the body of a cave man... Resilient, strong, masculine..." Hugo said.

"And I would be lying if I said there wasn't some benefit, but you didn't do this with my permission, you didn't ask me... What if it had killed me?" John asked.

"But it didn't kill, you just look-" Hugo was cut off as thick toes pressed into his neck.

"What if I had killed someone else? I came close, you know... Three skin heads." John said. Hugo couldn't speak but his eyes begged to know more. John rolled his eyes, taking his foot off the scientist, "You're terrible at this Doctor... You care more about it than your own life." John muttered.

"Did you feel any urges? Any instincts? How did you cope?" Hugo asked in wonder. John shook his head. Weaver was too stupid to value the danger he was in. John was so bemused he figured he would cut the doctor a little slack.

"There are triggers... I don't just progress like you have seen; I go all the way and then come back." John said. Hugo went still, staring at the man in awe.

"So it's... cumulative? The more times you change, the further you progress?" Hugo asked softly, licking his lips almost nervously, "What are the triggers?" he asked. John shook his head.

"This experiment is over, doctor, unless you give me what I want... You're going to pay my living expenses; rent, food, clothes... Then you get your answers." John replied.

"You're just a lab tech..." Hugo scoffed. John spun around and grabbed the scientist by the neck, pulling him out of the chair and slamming his back against the cabinets.

"You can't turn back the clock, doc. That isn't what I am anymore... I'm your experiment, I'm your curse. You can pick... Do you want my cooperation or my wrath?" John snarled, his teeth coated in saliva, his eyes burning with rage. Hugo gazed into the man's eyes for a long moment. John was confused by the expression, knowing it wasn't fear... and then he felt it, a hand on his groin... squeezing him through the fabric of his pants. John hissed in disgust before he dropped the man and slid back. Hugo crumbled to the floor before getting up onto all fours with an almost wild look in his eyes.

"That's it, isn't it? One of the triggers? Arousal? What else would matter to a primitive?" Hugo asked.

"ANGER!" John shouted in frustration. Hugo moved to make another pass but John grabbed him by the shoulders and tossed him. Hugo slammed into the wall, dropping to the desk before rolling onto the floor. Hugo panted, his body aching, but he had to trigger John to change more, he had to get him angry or horny. John shook his head, realizing there was going to be no way to negotiate with the man. Even as Hugo moved to get up, John stepped on his chest to pin him to the floor, pulling a vial of 320 out of the fridge. He removed the topper and gazed at the liquid.

"What are you doing?" Hugo wheezed gently, gazing up in shock. John suddenly pushed down on Hugo's chest, causing the doctor to call out. As he did, John tipped most of the vial back, the liquid splattering into Hugo's mouth. Hugo tried to spit it out but it ran down his throat, tingling as it went. Hugo squirmed and grunted beneath John, his eyes wide as he gazed upwards. Soon his fingers started to clutch and dig at the carpet, his heart racing.

"I'm turning your clock back. If the company wants to dissect anyone, I'm going to make sure it is you." John replied. Hugo's eyes went wide at the thought before he grunted, his eyes rolling into the back of his head. His fingers throbbed and ached as they started to stretch out longer and then thicker. The bones of his palm pressed out wider, stretching the meat and then his wrists got thicker. John slowly lifted his foot off of Hugo's chest and watched it grow. The bones increased in width and pushed apart, but it wasn't nearly as dramatic as John's case had been.

"What... what's the trigger?" Hugo grunted, his voice starting to deepen just a little as his cheeks grew dark with stubble. John crouched down, looking at the man.

"Maybe somewhere deep down in there you have a bit of fear after all. It isn't just lust and anger, its fear... The motivators of life. Maybe you're imagining what they might do to you? Lock you up in a box, run their little tests, send your hair samples off to other labs... I think you should have been scared a lot more before now, but now your fear is going to cost you your humanity." John smiled. Hugo stared up at him before he panted suddenly. His button up shirt grew tight as his pectorals and abdomen pushed out, then his biceps and triceps. With his torso getting so thick, soon Hugo's waist began to expand.

John moved over and sat down in a chair across from Hugo before he reached to unzip his pants. He curled his fingers around his log of a cock, starting to stroke it off, murmuring in delight at how strong and big his hands were. John grunted happily, feeling the blood course through him before he looked over at Hugo and how pathetic he was. Even as the doctor's dark hair grew out around his head and his jaw started to swell, it was clear that he was going to be an inferior specimen.

"You see doc, this is what real man is made of." John gloated, stroking himself off more and more, panting hard as his own changes were triggered. Once more John felt his chest expanding and his ribs spreading, but the changes weren't all that much. John had become so caveman like already, the changes were becoming subtle. His spine stretched just a bit, his feet grew, his ears rounded more... but all in all he was the man he had become. He was a caveman, a very manly caveman.

Hugo, however, had quite a bit of changing to do. The doctor writhed and stretched on the ground as his vertebrae pushed apart, expanded and then resettled again. His body ached and throbbed more than he had growing up. His shoulders creaked and his neck veins bulged as they all grew. In a desperate attempt to change the nature of his stimulus, Hugo tried to reach up his shirt to tweak his nipples, but the fabric had grown so tight he couldn't make progress and soon his hands fell at his sides, spasming.

John continued to watch his boss change, remarking on the changes. It was clear he was becoming a caveman, certainly, but his suspicions had been right about Hugo making an inferior specimen. His muscles weren't much larger than a Venice Beach muscle builder, he only had gained six or seven inches in height... but something was changing, something was changing indeed. Hugo thrashed against the carpet, grunting out as his jaw swelled, his teeth grew and his tongue thickened... and then it started; the brow growth.

Beneath the shade of the long black hair cascading out of his head, Hugo's forehead started to bulge. His eyebrows grew together but the bone beneath pushed forward, sloping the forehead and forming a bony sort of shelf. The protrusion of the bones shielded the light from his eyes, making them seem sunken, but in a way they almost looked glassy. Hugo suddenly rolled over onto his side before he pushed himself up, looking at John.

"Please... help. John help Hugo, John good... good John..." Hugo grunted softly. John let out of soft moan of early orgasm as he was caught off guard, only spurting a few streaks of cum before he leaned forward.

"Doctor Weaver?" John asked, but Hugo didn't respond, his eyes gazing around the room slowly. John swallowed a bit, "Hugo?" he asked. Hugo turned, giving John a toothy smile as his beard stretched out of his face. Hugo shuddered a bit happily as it reached six inches, his muscles pulsing. John took a deep breath, thankful that his change had gone in a very different direction... a different direction indeed.

****

A harsh buzzing woke John from his slumber and he let out a deep reverberating growl before he reached over to slam his fist across the alarm clock. His hand came down on a steel reinforced alarm clock, the buzzer turning off. He rolled over and looked at the time, a smile crossing his bearded face. Nine a.m. He hadn't had to wake up early in over a month. John slipped his hairy legs out of bed, his huge feet coming down onto soft carpet. He stood up to his towering height of seven foot two and stretched his arms out to either side, his massive hairy chest filling with air before he let out a yawn loud enough to rattle the windows.

John left his bedroom and walked past the bathroom, moving out into the living room. A lot had changed in the last month. His entertainment center was state of the art with blu-ray, streaming, and a plasma television screen as large as his bed. A stack of beer kegs sat by the window, always ready to fill a pitcher anytime John wanted it, though there was also medical equipment littered around; blood pressure monitors, blood sample kits, and a massive dry erase board filled with information...

Despite his physical changes, John still had his faculties. Sure, he had caveman impulses to fuck and beat and eat. He had a hundred dollars of steak in his fridge alone, not to mention the freezer, but with Hugo Weaver's unfortunate slip into a caveman mentality, John was Genetech's foremost expert on the G-320. He was valuable as a mind and as a research subject. He had refused to live in some lab at Genetech, wanting his freedom. To his surprise, Genetech had bought his apartment building. He lived there rent free and his neighbors were the doctors that studied him and worked with him.

John opened his fridge and pulled out two steaks, tossing them onto the pan on his stove. He drizzled seasoning across them and turned the stove on before he moved over to his couch and flopped down, spreading his legs wide. His thick cock sprung up and slapped across his hard stomach, throbbing with need. John chuckled to himself before he turned on some streaming pornography and sat back, starting to stroke his cock, knowing he was getting paid to wank himself.... It was hard to imagine life getting much better.

John ran his hand up and down, adding pressure and picking up the pace, moaning louder and louder before he slapped his other hand on there, squeezing his cock wild. As he tipped his head back onto the top of the couch, John started to fantasize about the people that would take 320, knowing that it took lust to bring them to their superior forms... Maybe he'd request helping them with that, showing them what a real male could do... After all, he was the alpha caveman. Hugo was a far cry from what a real specimen was like. Despite being in the middle of his jerk session, John took one hand off his cock and held it out, looking at his arm as he flexed. The muscle bulged tight beneath his hairy flesh. John grunted loudly as his cock started to spray out like a fountain. Life was good.
