Mark’s heart thundered in his exposed chest, his head spinning from the rapid transition. The last thing he remembered was being in David’s lab, fully clothed in his usual wardrobe of gym shorts and muscle shirt. “Fully clothed” may have been a stretch, as the small shorts left the majority of the blonde’s muscled thighs on display, while the loose, open sides of the top did the same for his tanned, sculpted torso, but it was still significantly more coverage than the bright cherry jockstrap he currently wore. And while the fit young man had spent countless hours similarly clad in locker rooms over the years, he wasn’t used to having his stuffed bulge and well-muscled rear so prominently displayed while on the floor of the gym itself.

Yet there he stood, staring at his grinning, nearly-naked reflection in the wall of mirrors while a buff, bustling crowd of bodybuilders lifted around him. Mark didn’t recognize the gym itself, it appeared to be a bare-bones operation in a converted warehouse, nor did he recognize any of the grunting meatheads openly staring at him as he hefted a pair of dumbbells. The unfamiliar men were mammoth mountains of muscle, each of their broad, imposing frames making the fit blonde feel small, a foreign sensation for someone who’d excelled at athletics nearly all of their twenty five years. They were also at least appropriately, if not fully, clothed, with all of them wearing small shorts at a minimum. Mark had never been to a dedicated lifter’s gym like the one he now found himself in, but the rugged environment perfectly complemented its rugged inhabitants. The men’s faces were as burly and meaty as the rest of them, with flat, square features that made the blonde’s sharp, pretty-boy edges look equally out of place.

But, despite the exposed stud’s internal alarm, none of his stunned surprise showed on that handsome face. As he stood and watched his impressive arms inflate with each rep, his tapering washboard tensing as he braced his core, all Mark did was flash his customarily smug grin. He caught himself staring at, and was simultaneously caught staring by, the beefy men around him, but none of them acted as if his bare cheeks or embarrassingly outlined package was at all out of place. If anything, they looked at him like they knew him, like he belonged there, a sensation that was exciting, comforting, and intimidating all at the same time. The longer he stood and hefted the weights, the more Mark began to realize that beneath the shock and surprise were far more pleasant, if confusing, emotions. He wasn’t just eyeing the men out of anxious curiosity, but with desire as well. The sight, smell and sound, their flexing bulk, their musky sweat, their deep grunts; Mark found himself responding on an almost instinctual level. He felt the way he would have if he’d woken up nearly naked in a room full of beautiful women, only now he could barely even conceive of soft, supple flesh, let alone become aroused by it.

His response didn’t make any more sense than his near nudity or his sudden arrival at the odd gym, but that confusion did nothing to mitigate the surging lust when one of the inexplicably handsome hulks lumbered over. The man stood at least six inches taller than Mark’s 5’10” height, with a broad-shouldered wingspan that suggested an ongoing struggle with most standard door frames. His hair was buzzed, his forehead was as imposing as his slab of a chest, and his square features were blunted, but the wide-eyed blonde had never been more attracted to anyone in his life. It was hard to tell how old the other man was, only that he was older, which only added to Mark’s fluttering stomach.

“Lookin’ good, runt,” the man grunted, emphasizing the heft of his arm as he wiped the sweat from his sloping brow. His draping, canary muscle shirt was soaked through, the once-bright fabric turned the color of mustard by the signs of his exertion. The front and back of the slinky top scooped so low as to render it pointless, leaving the meathead’s mammoth pecs and nubby nipples on full display while the open sides exposed the lumpy muscle and ample globes that the front and back ostensibly covered. It was clear from the cut that the shirt was made to emphasize, not obscure, the wearer’s stature, as were the tight, tiny shorts that barely stuck out from beneath the bottom.

“Th…thanks,” Mark stammered, an unfamiliar wave of insecurity nearly bringing him to his knees. Being a fit, handsome hunk in his own right, the blushing blonde wasn’t used to feeling anything less than fully confident about his appearance. He was chiseled and hung, with an eye-catching ass, an even better face, and a full head of golden, wavy hair. At the very least, he should have thought of himself as being on the same level as the lumbering stranger, if not on an elevated plane given the other man’s rough exterior. At the moment, however, all Mark felt was small. Weak. Insignificant. Clad in nothing but a jockstrap, his beauty wasn’t on display for all to see; his flaws were. He could feel his cock twitching in the stuffed pouch, but he made no move to cover himself when the man looked down.

“Let’s see how you’re doin,” the stranger said, nodding for Mark to put down the weights. The nervous blonde did as he was told, hesitating for a moment as he struggled with the idea of what was about to happen. He knew what the man wanted him to do; he just couldn’t believe he was about to start flexing for a stranger while tenting a jock in a crowded gym.

But that’s exactly what Mark did. He took a deep breath and broke into a double bicep pose, flexing the piston arms that most men would love to have, and which suddenly seemed woefully inadequate. Mark let out a gasp when the man reached over and gave his solid arms a squeeze, a whole-body shiver running through him on contact. “They’re still pretty small,” he said, uncertain where the words came from. He’d never once thought of or described himself as “small,” especially not to a stranger, but he couldn’t stop himself.

“It’s the effort that counts, champ,” the man barked, his gruff tone dripping with sarcasm. “Keep it up and maybe you’ll get here.” Mark actually whimpered when the man flexed, his aching cock oozing like someone turned on a faucet. He felt it happening, knew there was a growing damp spot, but, while a part of him was absolutely mortified, he couldn’t look away from the piledriver arm or the burly body to which it was attached. “I mean…probably not, but you never know,” the hulk grinned, nodding at the discarded dumbbells. “Pick ‘em up. Let me give you some pointers.”

Mark wanted to argue that he’d been lifting for years and already knew exactly what he was doing, but instead he sheepishly picked up the weights as instructed. His aching cock felt like it was going to shoot off his body when the man draped himself against his back, the musky, sweaty scent making his head spin as the man gripped his forearms to guide him through the curling motion. “What…what’s happening…” Mark finally sputtered, unable to believe it was his own nearly naked reflection he stared at nestled against the mountain of muscle.

“You’re makin’ a mess. Keep curling,” the man grunted. He tugged the jock down before the addled hunk could respond, grinning at the blonde’s surprised gasp and full-body blushing. “Cute little guy,” the stranger purred, giving the oozing organ a few rough tugs that nearly brought Mark to his knees. The stunned stud was mortified at all the reflected faces looking in his direction, and he knew he shouldn’t just be standing there curling dumbbells while a stranger jerked him off in public, but he was increasingly feeling like a passenger in his own body.

“Oh fuck…oh fuck…I’m gonna…” he gasped, erupting after only a few pumps of the rugged stranger’s fist. He told himself it was just the shock of the surreal circumstances, that his normally boundless stamina was still intact, but he didn’t fully believe it. The cracking, guttural howl he let loose was equally out of place, as was the way he’d started pressing back and rooting against the bigger man’s lap with his muscled bubble. Mark knew what he wanted; he just couldn’t bring himself to admit it.

Not that he had to. The mammoth meathead behind him simply grunted and gave his ass a squeeze, flashing another condescending smile. “Little thing’s got a hair trigger,” he chuckled. “How long can this guy last?”

“HHOOOOOOuuUUUHHH!” Mark howled and went up on his toes, dropping the dumbbells when a pair of stubby fingers forced their way into his virgin hole. Even through the shock and embarrassment he still had enough wherewithal to expect pain, and to feel a confused relief when none arrived. Instead, all he felt was an electric ecstasy shooting through him as the strong digits wormed their way deeper.

As he let himself be guided onto a nearby bench, Mark tried not to look at himself in the mirror. He tried not to stare at his slack-jawed, wide-eyed expression, or at the growing crowd that was gathering behind them. He didn’t want to think about what was actually happening, that he was whimpering and moaning and presenting his perky bubble to a roomful of musclebound strangers. And he didn’t want it to stop.

“How’s it feel,” one of the other brutes asked. He was a shirtless slab of freckled, ginger meat, with a dimpled face that could have been cute on someone more appropriately sized.

“Feel for yourself,” Mark’s most recent friend said, pulling his hand free.

The blonde groaned and arched his back when the other man’s fingers slipped inside, his spent cock already preparing to blow again. Mark didn’t understand how it was possible, how he could be enjoying the invading appendages so much when he’d never even thought about being penetrated before. He’d never even fooled around with another man, let alone wanted to be taken by a crowd of them, and, even on the rare occurrences when he’d considered crossing that line with a guy, he’d always envisioned himself being on top.

Now, being on top was the last thing he wanted, unless he was on top of one of the strangers’ laps with their undoubtedly thick log splitting him wide. Mark was mortified at the group’s laughter when the second man’s invading fingers made him cum again, but the embarrassing emotion only lasted for a moment before he had other concerns. “Fuuuuuuuuuuuuuck,” he cried, his sturdy arms giving out and sending him face-first into the bench when one of the men entered him with something other than their fingers. The man pressed down against his back, keeping him pinned and unable to even see who it was, though ultimately it didn’t matter. It wasn’t like Mark actually knew who any of them were, so it didn’t make any real difference which of their dicks was inside him, just as long as one of them was.

Mark was caught off guard by his ravenous desires, by the way he actually wanted to submit and be taken by each and every one of them. He started to hate the fact that he couldn’t see the gorgeous brutes as they slammed into him, and he was thrilled when that was finally rectified. By the time they flipped him over onto his back and hefted his legs into the air, Mark didn’t care how or why any of this was happening. As he gazed up at the naked slabs of muscle with their equally imposing cocks pointing in his direction, he felt a kind of contentment like he’d never experienced. As the men watched and stroked themselves while one of their peers pummeled his battered rear, Mark relished the sensation of their warm eruptions splashing all over him. He could only imagine how he must look, his sculpted frame and handsome face increasingly covered by the seemingly ceaseless, sticky rain, but he didn’t care. He could figure out the details later. No one he knew was there to witness his debasement, and he didn’t have to say a word about this after it was all over.

The prone, penetrated pretty-boy lost track of how long he lay there, of just how many men entered him or erupted all over him. It all blurred into a lustful haze of sweaty, sticky muscle, deep grunts, and bright bolts of bliss. The brawny brutes seemed to have endless stamina, and Mark was somewhat surprised that even his own suddenly eager rod kept popping over and over again. He knew that he should have been running out of steam, but it felt as if he could have kept going forever.

“Wow. This really is immersive.”

The combination of a familiar voice speaking an actual sentence, not merely grunting, pulled Mark out of his haze. He finally noticed that the shoulders his thighs rested on didn’t feel nearly as broad, that the furry skin wasn’t as smooth against the bottoms of his legs, and that the cock plunging in and out of him wasn’t one of the imposing clubs. “Da…David?! What…what the fuck is happening,” he cried, torn between a fresh wave of humiliation and a burning desire for the other man to keep going. Though he wasn’t one of the oversized hulks, the dark-haired scientist had a fit, impressively strapping frame for someone pushing forty. It wasn’t as sculpted or honed as his own, but Mark quickly realized he no longer actually cared what another man looked like, as they’d all become equally attractive to his overloaded brain. When they’d first met, he’d thought that the older scientist was handsome in a distinguished way, but he hadn’t actually been turned on by him the way he was now. “Oh…oh fuck…oh fuck…fuuuuuuck,” Mark groaned, now acutely aware of just how cum-slick he’d become when he blasted all over himself again. “What…what am I doing? How did I get here? The last thing I remember is being in your lab! Then I was here…doing this…” he sputtered.

“Oh! Uh oh,” David said, his own meaty frame taking on a rosy hue as he blushed. “This is unexpected.” He slowed the pace of his thrusting and started to pull back, but stopped when Mark let out a whimper.

“No! Don’t…don’t stop…just…one more,” the sticky blonde begged, his unquenched desire no match for his need for answers.

“Oookay,” David said with an awkward laugh, resuming his thrusting. “We clearly need to take a better look at these uploads…this much of someone’s core identity shouldn’t still be intact…haven’t seen it with anyone else, but that doesn’t mean it can’t…happen…” he said to himself. He stopped talking when he saw the blonde’s confused expression and focused on the task at hand, still blushing as he hammered out a sizeable load. “That better,” David asked, gently guiding Mark’s legs back to the bench.

The blonde laid in silence for several moments, dizzy from the overwhelming experience and the still-smoldering pit of lust at his core. He went purple when he finally sat up and saw his cum-matted hair and dripping frame in the mirror, the now-naked mountains of muscle turning their attentions to each other. “What the fuck, man,” he finally spat with a short laugh.

David reached over and put a hand on Mark’s broad back. “How much do you remember,” he asked, looking uncomfortable as he sat naked amongst the rutting crowd.

Mark’s cock twitched as he thought about it, the older man’s hand on his back sending slight shivers through him. “I remember getting to your lab, and you setting me up to do the scan…but then all of a sudden I was here! I just…I opened my eyes and I’m lifting weights wearing nothing but a jock strap, and then these guys just…they just…” he trailed off and looked down at his crusty pecs, his expression like a deer in headlights. “Where even are we?!”

David took a deep breath, trying to be careful in his word choices. “Do you remember what the scan was for?”

Mark nodded. “Yeah, you were going to use my brain waves or whatever to help program an AI or something. Like a fancy OnlyFriends, right?”

“Exactly. Instead of having to rely on an actual person, we found a way to copy someone’s thoughts and memories…their whole personalities…making for a much more realistic VR experience than a simple AI bot. With the way things work now, with people actually experiencing physical sensations from a virtual world, we’re trying to make the interactions as realistic as possible. Volunteers like you give us the template to build the more realistic models from. That’s why you look exactly like Mark, and why you’re seeing my naked body the way it looks in the real world. Our brains fill in the gaps to make it all digestible instead of…”

“What do you mean ‘why I look like Mark’,” the blonde interrupted. “Who else would I look like?”

“That’s what I was getting at,” David said, motioning around the room. “You’re not actually here. There IS no ‘here’. This is all a pre-programmed scenario, a meathead gang-bang with a buff pretty-boy. We’re not really in a gym, and you’re not really Mark.”

“What?! No! That’s…that’s crazy,” the blonde stammered, the color draining from his face. “Of course I’m me!”

David shook his head. “Mark is out there in the real world, just like I am. You’re made up of Mark’s thoughts, memories, and impulses, but you’re not…” he trailed off and took a deep breath, motioning to the orgy unfolding around them. “Was ‘Mark’ ever so turned on by other guys? Was ‘Mark’ ever so desperate to get fucked by another man? That was all part of the scenario, details that were added to Mark’s brain waves to create this specific version of you for the audience. That’s how this all works. People can watch, or they can participate. Right now that audience is just me since I was testing the latest scans, but…”

“But what?!” Mark cried. “What happens to me now?! How do I get out of here?”

“You don’t,” David said, his bushy brows furrowing. “Once the sequence is turned off…”

“WHAT?!” The blonde hopped to his feet, desperately trying to refute what he’d heard. It would have been easier if it all hadn’t made such sickening sense. The new impulses raging within him, the confusing desires, the gaps in his memory; they all pointed to David telling the truth, as much as he wished otherwise. “So that’s it, then? I just…go away?”

“Normally, yes,” David sighed, burying his face in his hands. He laughed when he pulled them away and looked down at himself, shaking his head. “Really didn’t think I’d be untangling ethical dilemmas with my dick out,” he chuckled, his expression softening as he looked at the stricken blonde. “You’re the first one of the uploads to express any sort of awareness. I don’t know if it’s something specific to Mark’s brain, or if it was a glitch in the system, or what. But, knowing what we now know, I can’t just turn you off.”

“What CAN you do, then,” Mark asked, afraid of the answer.

David hopped off the bench and squeezed the younger man’s hand. “I guess we’ll have to figure that out together.”

**********

Mark let out a contented sigh as he kneaded David’s furry pecs, his fingers drifting through the cum-matted hair. He’d already launched several loads onto the older man’s chest, and each twist of his hips brought him closer to another one. “You feel fuckin’ great today,” he grinned, loving the sensation of David’s cock lighting him up from the inside.

“Someone’s in a good mood,” the older man said, squeezing the blonde’s muscled thighs as they straddled his lap.

“I just love it when you come to visit,” Mark shrugged, motioning to the opulent bedroom around them. A sandy beach could be seen through the windows on one side, while a bustling metropolis loomed outside the other. “I get to repay you for building all of this for me.”

“Least I could do,” David said. “So everything’s still going okay in here?”

Mark nodded, looking sheepish. “It’s amazing. It’s all so…real. Even knowing what I know, I still get embarrassed walking around town in nothing but a jockstrap…or, you know…less,” he said, blushing.

“Sorry about that. It’s what you were originally programmed with, and since we still don’t know exactly how you became aware, I don’t want to poke around too much in there. I’ve tried to throw in a mix of people, but I can make everyone naked if you…”

“No, it’s fine,” Mark interrupted. “It’s actually kind of fun. And I like having guys I can undress, you know?” He blushed as he said it, still unaccustomed to his altered desires. Like his permanently limited wardrobe, since he’d been created as an insatiably horny power bottom, that’s how he remained. It left a discrepancy between “Mark’s” memories and current reality, but it was one that he was quickly getting used to. It helped that David had built a world where anything goes, where a walk to the coffee shop could turn into him getting fucked in the middle of a crowded cafe and no one batted an eye. The older man had also populated that world with various other “uploads”, meaning that most of the people Mark encountered weren’t the one-dimensional caricatures he’d encountered in the gym, though the meatheads were still around. The end result was a world so vivid and realistic that Mark could almost forget that none of it was real. “It’s, uh, really hot being the only one without anything on,” the blonde admitted with a bashful grin.

“I’ll be sure to remember that,” David purred. “Anything else you want me to add?”

Mark shook his head. “Not at the moment. You’ve already given me an ocean-front mansion and my own personal city to play with. I mean…you COULD come and see me more often,” he grunted, the pressure building. “I like it when we’re both naked out there.”

“That’s…certainly…something,” David said, his stubble-covered cheeks going crimson. The world he’d built seemed just as real to him when he was in it, making their naked strolls through the city an exhilaratingly embarrassing experience for the relatively modest man.

“Look at you blushing,” Mark teased. “That model of you at the club isn’t nearly as shy.”

“I’m glad you…enjoy that…” David groaned, rapidly nearing the edge. Mark had asked him for a go-go boy version of himself, and he’d grudgingly agreed. The older man was both mortified and flattered at the thought of his doppelganger stripping and dancing at a club, but he had a hard time saying no to the handsome hunk. It wasn’t an official upload, Mark wanted to keep David as the real thing, but the younger man wasn’t above a toy version he could play with.

“Gonna enjoy it even more when we go there after this,” the blonde said, increasing the speed of his writhing. “He’s a better dancer, but you’re more…authentic.”

David groaned and arched his back, erupting into the younger man as he thought about their last trip to the virtual club. Mark had made him wear a pair of gold bikini briefs that he’d been forced to flaunt as he’d awkwardly shimmied and swayed on the dancefloor, moving his meaty frame with no more coordination than he did in the real world. David found the experience equally mortifying and liberating, a common occurrence whenever he visited the virtual stud. “And what are you going to make me wear this time,” he finally asked when he’d caught his breath and Mark had blasted all over him yet again.

“Absolutely nothing,” the blonde said. He slid off the older man’s lap and pulled him to his feet, giving David’s hairy, meaty globes a slap. “I mean, nothing other than me. We haven’t actually played with your other self as a pair, and I really, really want to give that a try.”

David blushed but didn’t argue as Mark pulled them into the shower.
