PART 1
This is John and Mark. John and Mark have been best buds since they were sophomores in high school. Inseparable, some might say. They’ve grown even closer in recent years. So close, in fact, that Mark seldom leaves John’s side… or sides.
Confused? I would be to. There’s only one man in that picture after all. You see, John turned his friend Mark into a pair of briefs a while back. Turns out that the boys had gotten ahold of a rare bottle of truth serum—the kind that makes everything you say become the truth—and someone got a little too creative.
John promised it wouldn’t be permanent. He promised he would only keep Mark in this humiliating state for a few days. But a few days turned into a few weeks. A few weeks turned into a few months. And now, one year after drinking his first drops of truth serum, Mark isn’t any closer to being human again. After all, he is John’s favorite pair of briefs.
But Mark hasn’t forgotten. Each day he waits, patiently cradling John’s massive package. He waits for an opportunity that he’s not sure will ever come, the opportunity to get revenge.
Fortunately for Mark, that opportunity is about to arrive. The Changing Room still has big plans for these two. All we need is just a few drops of truth, and a few simple words…
Blake already knew the rules. He’d read extensively about the “truth serum” online. He’d heard about the hot games people had played, the hot fantasies that had become reality, he’d read about the hot accidents that became irreversible once the effects wore off.
But Blake wasn’t here to play any games. He knew exactly what he was doing. He knew exactly how much of the serum to take, the exact words to say, and the exact order to say them in. He couldn’t screw up; this plan was foolproof.
And yet, as he stared down at the emerald green liquid, fear gripped at the corners of his mind. What if he wasn’t ready? What if he did screw up? What would that mean for him?
“BLAKE!” He jumped. The voice came from a few inches below him. Great, he thought. It was Stan.
“Man, the gym is pretty crowded today, huh?” Stan said, motioning to the other guys in the locker room. He was right, the little dork. The gym was bustling with post-thanksgiving stragglers, looking to drop those couple of pounds they gained over the week. Only these guys didn’t have “a couple of pounds.” Most of them were fat, old, objectively unattractive (at least to Blake). By and large, the gym wasn’t populated by the most attractive guys. Blake lived on the outskirts of town, and there was a retirement home just a block away from the gym. Blake didn’t consider himself very attractive—average by most standards—and yet he looked like a bodybuilder next to most of these guys.
Stan was a prime example. Stan had been Blake’s lab partner freshman year of high school. They ran into each other at the gym a couple months ago, and Stan had been following him around ever since. It was obvious how attracted to Blake he was, but Stan was not his kind of guy—at all. He was short, pasty, and had a nasally, high picked voice that rang around the locker room like a high pitched bell.
“Blake, did you hear me?”
“What—yes. Sorry, I…” his mind was elsewhere. Blake was thinking about what was waiting for him outside that locker room. He was thinking about what he was going to say to transform him. What were the words again? “It must be thanksgiving, you know.”
“RIGHT!” Stan said with an obnoxious laugh, “it’s that pumpkin pie. I’m telling you. My grandmother makes the greatest pumpkin pie…” as Stan continued to rant about his “epic” thanksgiving dinner, Blake saw a flash of skin from the corner of his eye.
It was him. Alex. God, he looked incredible. Even by the rather lax standards of their gym, Alex was one of the hottest guys on the planet. How he had even ended up training at a dump like theirs was a mystery to Blake, but he didn’t care. He got to be blessed with the glorious sight of Alex’s perfectly toned muscles, his soft cream skin and warm welcoming eyes every Tuesday and Thursday. After all, he was Blake’s personal trainer.
“Blake!” Alex spotted the two from across the room and sauntered over, beaming. “How’s it going bro? How was thanksgiving?”
Blake froze. The words caught in his mouth. The bottle of truth serum gripped tight in his fist. “Good!” was all he was able to get out.
Alex turned to Stan. “And you name was…?”
“STAN!” he said, a little too loud. If he had a crush on Blake, he was absolutely in love with Alex. He grabbed the jock’s hand and shook it. “We’ve met a couple of times. You just probably don’t remember. It’s okay. I forget things too. It’s fine.”
“Right,” Alex said. He turned back to Blake. “See you out there? Ten min? It’s arm day today! Gotta get those biceps nice and big.” He patted Blake’s sad excuse for an arm, and Blake had to hide his blushing face.
“Arm day, yeah. See you out there!”
Alex was gone as soon as he came. Stan made an exaggerated sigh. “Why are all the hot ones straight, know what I mean? Like if only he was gay…”
If only. Blake gave a little laugh. He laughed, not because of how improbable that was, but because by the end of their session, Alex was going to be very gay. More than that, Alex was going to be his boyfriend. It was the truth he had concocted in his mind when he had purchased the serum online. All he needed was a couple of drops and the confidence to say the words out lout. But if there’s anything Blake was sorely lacking, it was arm muscles and confidence.
“Hey, what’s that bottle you got there?” Stan pointed to the serum, “is that a supplement? You know my grandma said those can make your balls fall off.”
Blake pulled it back. “No, it’s… um…” and then an idea started to form. A small, sinister, brilliant idea. “Actually,” Blake said, “it is a supplement. But a very special one. Want me to show you how it works?”
Stan nodded vigorously while Blake looked around for an empty changing stall. There were too many guys around to do this in public, and Blake only had ten minutes.
There’s a lot I can do in ten minutes, he thought to himself, and the two disappeared into the showers.
“Can I get you anything, sir?” The clerk looked up at the large, muscular man as he walked into the store. He was looking around at all the supplements, the vitamins, the protein shakes. But John wasn’t reading any of the labels…
“Yeah,” John said with a charming smile, “I was wondering if I could get a few drops of the… um… ‘special’ shake.”
A flash of confusion across the clerk’s face. Then, recognition. “Right away,” he said, and disappeared into the back. The second he was gone, John stuck a thumb into his sweat pants and pulled them open.
Mark was writhing and squeezing on his junk. John winced. He was starting to get more violent, and if he didn’t put him to rest soon, there would be another grown man standing in the middle of the shop with them.
By the time the clerk returned, John had shrunk a half foot, and his muscle tone was going down. Fast. “Thanks,” John said, grabbing the tiny green shot from the clerk’s hands and throwing it down his throat. He rushed out of the shop, where no one could hear him, and said out loud to himself:
“I am a jacked up muscle god, and Mark is my favorite pair of underwear.”
He felt himself grow taller, the lost muscle mass returning in a matter of seconds. And Mark stopped writhing. He was back to being just another pair of cozy briefs.
John sighed. He had to find out about the hard way: the truth serum’s effects eventually did ware off. It started about a month ago, when he started loosing muscle, and Mark’s reflexes started to return. He had an arrangement with the store owner: just two drops of the truth serum a month. Enough to keep his body hard and Mark at bay.
But this was the second time he had gone this week. Though he puffed out his chest and put a smile on his face, deep down John feared that the effects might ware off altogether, and nothing would be able to stop Mark from being human again, and enacting his revenge…
“What are we doing in here?” Stan asked as Blake closed the shower curtain.
“Take off your clothes,” he ordered. Stan looked taken aback. Then, he blushed.
“Aren’t you afraid someone will see us?” he said as he peeled his shirt off. Blake winced at the sight of his lumpy, pimply chest. He wouldn’t have to look at it for much longer. “Aren’t you going to get naked too?” Stan asked.
But Blake was already unscrewing the cap to the bottle. He knew he needed to save some for Alex’s transformation. All he needed now were a couple drops. He savored their sweet taste as they slivered down his throat.
“Um… Blake?”
Blake grinned. He could almost feel the power pulsing through his veins, the words like fire as they came off of his tongue.
“I really love your chest, Stan,” Blake said.
Stan blushed. “Y—you do?”
“Oh yeah, all that hair, all that muscle. You’re a real daddy, you know that?”
Flattered, but confused, Stan opened his mouth to speak, and that’s when he started to feel it. A soft rumbling under his skin. The prickling of hairs poking out from his pores.
“What’s… what’s… is that my voice?” It was rich, deep. It echoed off the walls of the shower and made Blake’s dick jump in his gym shorts. He stood back to accommodate for Stan, who’s size was increasing by the second.
It was his muscles, mostly. In just under a minute, the young man’s muscles had swelled to bodybuilder proportions. The veins bulged under his skin as hair continued to grow in fields across his chest, over his arms, and down his legs. Blake had to resist the temptation to reach out and rub his thick carpet, to smell his hairy pits, growing ever thick with hair and musk.
“Grrrrrrr…” Stan growled. He brought both colossal arms up over his head and flared out his pecs. As he did, a fresh crop of hair covered them, all grey.
Blake looked to to Stan’s face. Sure enough, he was aging rapidly. The young man who had just turned 22 several months ago was now encroaching on 45. Stan closed his eyes and gave another hearty growl as a silver daddy beard burst through his chiseled chin.
“Fuuuuck this feels good,” he said, bringing one hand down to grip his package. The second his hand touched the silky sheen of his underwear, Blake saw the bulge inflate and swell. So much, that he was beginning to see the head of his mature, beer can cock pressed against the soaking fabric. “Fuck, I need to release,” Stan continued, “get down on your fucking knees, boy.”
But Blake was still admiring his creation. Only now, Stan’s transformation had far surpassed the limits of his simple statement: he was looking closer to 55 than 45, many of his hairs turning grey. His skin grew rougher and looser around his muscles, and the veins were no longer visible under the pounds of access fat and flab that he was putting on. He was still muscular, very much so, but he was more sugar daddy than pro-bodybuilder.
Blake shook his head. “I… Sorry… I’ve got…” But Stan was advancing on him, stepping forward with a seductive glint in his eye. Apparently all of his attraction for Blake was still there, and only heightened by the increased testosterone.
“Boy, I said get down,” Stan continued with a stern, fatherly gaze. For Blake, it was insanely hot, and he was just about to drop down and unveil that beast of a dick when he remembered Alex, waiting out on the gym floor. His perfect muscles, his dreamy eyes.
No. He couldn’t get distracted. Not now.
In one swift movement, he slipped past the muscle bear and out the shower door. He didn’t even look back. He booked it out of the locker room and into the gym.
Alex knew he had to be stretching. He knew he had to be getting ready for his training session. He knew he should be doing anything but staring at the guy who just walked into the gym.
And yet he was. Not in a sexual way. Alex was straight as a nail, of course. But there was something about this man, how he just sauntered in and commanded everyone’s undivided attention. Perhaps Alex was just used to being top dog at the gym; we was objectively the hottest guy, and he wasn’t naive about that fact. But when John walked in, with his jacked up muscles and cocky swagger, he put Alex to shame.
Alex was so focused on John lifting on the other side of the room, that he didn’t even notice Blake talking right next to him.
“Alex… Alex?”
“What? Sorry I… sorry. Just thinking.” Alex shook off the image of John and turned to his client. “Now, you ready to get those arms nice and big?”
“Actually,” Blake cleared his throat, “there’s something I wanted to talk to you about.”
“Yeah sure, what up?”
Blake took a deep breath. He was so focused on the image of Alex as his boyfriend, so distracted by the image of Stan transforming in the shower stall, that he didn’t even notice until right then:
The bottle was missing.
He bent down frantically, scanning every conceivable inch of gym mat to see if he dropped it. “Hey Blake?” Alex asked, “bro, is everything okay?”
“Fine I just… sorry… have you seen a little green bottle lying around anywhere?”
Alex cocked his head. “Sorry man. I haven’t. Hey, what was it you were going to tell me?”
Blake looked up. Perhaps there was a chance the serum was still in him. That he could still say anything and have it be the truth…
“I was going to say, how does it feel to be my boyfriend?”
Alex’s stare grew glazed, his mind running wild behind his wandering eyes. And then… he laughed.
“You’re a funny dude,” Alex said, shaking his head. But then he stoped. Blake could see that his eyes were fixed on something—or someone—all the way across the room, over by the lockers. “Who on earth is that?” Alex said. Blake knew instantly: it was Stan.
Everyone gawked as this giant muscle bear, wearing nothing but a skimpy pair of briefs, sauntered out onto the floor, grinning from ear to ear like he was hiding some big secret. Blake could smell the musk coming off of him yards away, and as much as he hated to admit it, it was a huge turn on.
“Morning boys,” Stan said as he approached the two.
Alex searched for recognition in the man’s eyes. Blake thought he saw the slightest hint of genuine attraction. “Do—do I know you from somewhere?” he asked.
“Why of course you do,” Stan said with a sly wink to Blake, “we’ve been going out for almost two years now.”
Blake’s jaw dropped. It was him. Stan must have taken the potion when he dropped it on his way out of the shower. Only he couldn’t, there was no way…
But when Blake turned back to Alex, he knew the change had already begun. It was the slight glint in his eye, the way he caressed Stan’s muscular body with his gaze. But most of all, it was the obvious boner Alex was popping in his shorts.
He was gay as hell now. And gay for Stan, out of all people.
The horny trainer jumped up and embraced his new lover, furiously making out as his hands ran all over the man’s furry muscles. “Whoa,” Stan said with a laugh, “slow down there tiger. Let’s wait ‘till we get back to the house.”
“But I don’t wanna wait,” Alex whined, stroking his daddy bear’s beard. “C’mon, let’s give them a show they’ll never forget.”
Blake was seething as he watched Stan slip a finger down Alex’s shorts and tickle his puckering hole. “Well, I’ve always wanted to do something public…”
“Wait, no. STOP.” They both stared at Blake, who marched up towards them. “Give me back that bottle,” he demanded, “that serum is MINE.”
“What serum?” Alex said, toying with Stan’s nipple as the burly man gave a hearty laugh.
“I don’t know what he’s talking about,” he said with a scoff, “he’s just a dumb horny twink. Isn’t that right Blake?”
Blake shook his head. No. This couldn’t be happening. But he was already stating to feel himself shrink down. His skin grew softer as he lost about two years, and his voice grew high pitched as he pleaded: “Stop… no… please…”
“Oh yeah,” Stan said with a sick grin, “you’re a stupid daddy chaser with a giant ass and an insatiable need to get fucked. But I ain’t gonna fuck you. Alex, would you fuck him?”
Alex cocked his head, “eh, he’s a little skinny for me. LOVE that ass though.”
Ass? Blake thought. And then he felt himself swat, instinctively, letting his bulbous butt explode out of his gym shorts and jiggle up and down as a tingling feeling overtook his now tiny body.
“No… stop… fuuuuuuuuuck.” People from all over the gym were beginning to stare. Blake needed to get out of there. Fast. He ducked his eyes down and rushed back into the locker room. As he ran, his butt grew even larger, forcing him to waddle rather than walk.
The second he had a shower to himself, he slammed the door and shoved two fingers up his ass. “OH,” he moaned, violently pawing at his throbbing boy pussy as the need to be fucked grew like a primal urge inside of him. It was like being stranded in a desert without water, and his two, skinny twink fingers just weren’t cutting it.
Blake rubbed his ass up against the tile wall. Fuck, he thought, this is humiliating. Here he was, a stupid horny twink, resorting to twerking up against a shower wall because no one would fuck him. And oh how he needed to be fucked. And not just by any dick. Stan was very specific with his wording; Blake wouldn’t be satisfied until he had a massive bodybuilder dick shoved up his pulsing asshole. And where on earth was he going to find one of those?
“Need some help?” came a voice from Blake’s right. He turned to see one of the single most gorgeous guys he had ever laid eyes on standing right there, rubbing his cock through his blue briefs.
“My name is John,” the man said, “looks like you might need some help with that.” Blake wanted to say no. He wanted to find that bottle of truth serum and wreak havoc on Stan and his new boyfriend.
But he also needed to be fucked. And he was the most gorgeous specimen on the planet offering to pound him silly. How could he refuse?
Blake turned around and bent his back, sticking his bubble but straight in the air and flashing his hole. “Fuck me daddy,” escaped his lips, and he didn’t even have time to process those words before John took off his briefs, threw them aside, and reared up behind his victim.
He was already hard as a rock. Seeing Blake transform into a hungry bottom slut was one of the hotter things he’d ever seen. Now, he was ready to give that ass the pounding it deserved.
“FUUUUUCK!” Blake screamed as John’s 9 inch cock slid into his ass. There was a moment of brief pain before Blake felt his muscles relax, his sphincter clutching the veiny dick as it slid in and out, in and out, each time with more ferocity than before.
“Yeah, you like that boy?” John said, giving the jiggling piece of meat a hearty slap. Blake let out another moan. At this point, he was practically grinding down on the John’s cock. Both of them were so enamored, they didn’t even notice the fact that John was getting thinner, his hair getting darker and shaggier, or that his underwear had vanished from outside…
Blake closed his eyes and gritted his teeth. Cum was spewing from his dick, but the orgasm wasn’t even close to being over. If anything being fucked put him in a place of perpetual orgasm, wherein the pleasure was so intense, that the world around him vanished into a whirlwind of color and sound. Nothing mattered but the dick slamming into his ass, and there was no way for him to notice that the guy who was fucking him was no longer a jocked up meat head, but an average college guy named…
“Hello John,” Mark said from the doorway. John spun around to see his friend, human once again, and twirling a small green bottle in-between his fingers. The spell had worn off. It was official.
Panicked, John made to move when Mark said, “oh no, you won’t stop fucking him. You’re going to keep going until I say ‘stop.’” Sure enough, John continued to pound the hungry twink’s ass, despite him being oblivious to the entire situation.
His voice was shaking as he pleaded with his former friend. “Mark, please, just let me go. I’m sorry, you won’t ever have to see me again.”
“Oh I’ll be seeing you for a long time,” Mark said with a sly smile, “why would I give you up? After all, you are my favorite dildo.”
John could feel it coming, the sinking feeling that not only had he failed and would spend the rest of his life paying for it, but that his entire body was collapsing into itself. He felt his insides compress and turn to hard silicone. He felt his hands and feet disappear into his shrinking rubber body. He tried to let out one more scream before his face was swept up into the twink’s steaming hot hole, where it would fulfill itself as the penis head to Mark’s favorite sex toy.
The very last thing he saw was Mark’s proud face, and then everything went black. Just as it did, he felt a rush of pleasure overcome him, an orgasm unlike anything a human body could experience. He screamed internally with extreme pleasure as the walls of Blake’s ass enveloped him, and within seconds, John’s body was frozen solid. Nothing but hard rubber slathered with sweat and cum.
“FUUUUUCK!” Blake let out one final shout as the last bit of cum erupted from his dick and coated the shower floor. He pulled the dildo out of his ass and looked at it, confused. That’s when he noticed Mark standing there in the shower door, smirking.
“It’s a shame,” Blake said, “I thought he was really cute.”
“Yeah,” Mark said, “but he’s always been kind of a dick.” He winked, taking the dildo from Blake’s hands and replacing it with the green bottle. “I think this belongs to you.”
Blake looked down at the truth serum. Mercifully, Mark had only taken a few drops, and though Stan had drunken two thirds of the bottle, there was enough to do a number on him—and possibly get Alex back.
“Wait,” Blake said, “where are you going?” Mark was already halfway to the exit.
He turned back. “I’ve been gone for almost a year now. I have to let everyone know I’m okay.”
“Sure… but…” Blake held up the bottle with a grin. “Don’t you wanna have some fun first? There’s enough in here for two.”
Slowly, Mark began to walk forward. “What did you have in mind.”
“The same thing as you,” Blake smiled. “Revenge.”
PART 2
“Well, how do I look?”
Blake might have been too modest to say it, but he had done an incredible job transforming Mark. The two had decided to have a little fun with the truth serum before going back out to punish Stan. Blake had started by turning Mark into the best version of himself, which meant perfect hair, perfect muscles, and the perfect dick. He hadn’t seen it yet, but he desperately wanted too. He was still a cock-hungry bottom slut after all.
“Still horny?” Mark said, taking the words right out of his head. Blake nodded. He didn’t want to say anything out-loud in case the truth serum was still in effect. If there was anything Blake had learned today, it was to be extremely careful with this powerful elixir. Just one sip, and anything you said became the truth. Anything.
“Here,” Mark reached out a hand, “I’ll turn you into something good. Not this twink bullshit.”
“Really?” Blake said, relieved.
“Of course!” Mark said, “it’s the least I could do. You’re the reason I’ve got this incredible body instead of being wrapped around John’s disgusting ass.” He laughed as he gave a little flex, sending a fresh blush across Blake’s face.
He handed the bottle to Mark, who popped open the cap and took a couple of drops. Blake felt a pang of fear as he saw the contents of the bottle: there were only a couple of small sips left.
“Alright,” Mark said, “who’s your favorite actor?”
“Sorry?”
“Actor, celebrity, ANYONE! Someone you find hot. Someone you’ve always wanted to be.”
The question stubbed Blake. Who wouldn’t he want to be? Anyone but the flimsy, fat-assed daddy chaser he was now.
“Can it be an athlete?” Blake asked.
“Anyone,” Mark said.
The image of him had crossed his mind briefly, before sticking and growing into swarm of fantasies that were now swirling around his head. They were about to become a reality.
“Well… I’ve always thought Gus Kenworthy was really hot.”
Mark gained. “Well today’s your lucky day, because you ARE Gus Kenworthy. Pro Olympic Skier, social justice champion, and handsome, hairy, and huge piece of man meat.”
The words felt like candy to Blake’s ears. Immediately, he felt a warmth overtake him, flooding his veins like adrenaline. This was nothing like the last transformation, which felt cold, humiliating. At that moment, Blake felt like he could fly.
“Ooooohhhh…” the young man moaned. His body shivered as the flab from his over-sized bottom ass vanished, transforming into solid muscle with the perfect amount of fat. The muscle ran down his thighs, bulking them to ham-size and pressing them against his formally loose briefs. Now, the fabric highlighted every curve of his astonishingly toned lower half, hardened and chiseled from years of skiing on the slopes of Colorado.
“Is… is that my ass?” Blake stuttered.
Mark laughed, “I think the real question you should be asking is: are those your abs?”
Blake looked down. The flood of adrenaline had made its way up to his torso, where he could feel his chest tighten into a solid rack of abs, his obliques turning to hard lines leading down to his crotch.
Muscle mass filled his pecs like two sand bags, and the sudden addition of weight to his frail frame caused Blake to stumble back. By now, his whole body had gone numb. He couldn’t feel himself fall to the floor, he couldn’t even hear himself moaning and screaming in intense pleasure. He could only feel the heat and the testosterone as it continued to shape and expand his muscles, broaden his frame, and cover his skin with a fresh layer of dusty blonde hair and tattoos.
“FFFFFFUUUUUCCCCCKKKKKK.” His hands were running wild across his body. His arms had just finished packing on lean muscle when the final muscle began its long awaited transformation. Blake had never seen Gus’ dick. He could only imagine the meat that guy was packing under all those snow clothes. But when Mark had said “huge piece of man meat,” he wasn’t just talking about his body…
It started out like the beginning of an orgasm. All the muscles around the base of his dick tense, all the blood went from his muscles down towards his crotch, sending fresh shivers throughout the rest of his body.
His head jerked. His mouth dropped. And Blake—or rather Gus—let out one final moan before firing his load off into his underwear. As he did, his dick grew by a full four inches, almost bursting the seams of the wet boxers as his tiny twink cock transformed into a true Olympic penis.
It was a full minute before Gus’ eyesight returned. The intensity of the orgasm was such that he could barely see anything. When he finally did, the first thing he saw was Mark, his gorgeous jock body hovering over him. He reached out a hand, helping Gus to his feet.
“Here,” he said, handing him a bottle of water, “you need to replenish.”
Gus took a big sip, and handed the bottle back to Mark. He caught a glimpse of himself in the mirror, his sweaty, bulging muscles sending a fresh rush of lust through his newly transformed body. He couldn’t stop looking at himself, admiring his olympian form, his handsome scruff, his irresistible smile.
“Fuck man… I’m hot as hell!”
“You must be,” Mark said, “neither John or me ever came like that when we transformed. As a matter of fact… we never came at all.”
“Well,” Gus said, “I guess it must have been how you said it.” He leaned in to give his new friend a kiss…
…But he pulled back. “Um… sorry.” Mark gave a nervous laugh. “I’m straight, actually. I’ve got a girlfriend. Well, I had a girlfriend a year ago. God knows where she is now.”
“I’m sorry.” Gus said, visibly disappointed.
Mark gave a weary smile, “I just don’t feel that way about guys, you know?”
A light went off in Gus’ head. “Do you want to?”
“Sorry?”
“Be gay. Or bi. I mean… wouldn’t it be nice to broaden your horizons?”
“I mean sure but, I can’t just choose to be gay.” At the same time, they both looked down at the truth serum, then back up at each other.
“You’re not suggesting—“
“—It would be totally up to you!” Gus said, defensive. “I know you were forced to change in the past. I don’t want to force you to do anything now.”
Mark looked into Gus’—or Blake’s—eyes. He saw a man who he admired, even if he wasn’t attracted to him per-sea. But deep down, he knew that he wanted to be.
“Sure,” he smiled, handing Gus back the bottle, “why not?”
No one in the gym ever used the sauna. It was relatively tiny, tucked away in the back of the locker rooms, and the temperature controls never really worked. However, this made it the perfect spot for a late night hookup, which was exactly what Gus anticipated would happen.
He closed the door behind Mark. He paced around in eager anticipation. “Did you drink it?”
Gus nodded as he held up the bottle. “There’s enough for one more sip after this,” he said with an air of gloom. After a moment of silence, Gus smiled cleared his throat. “Well, by order of the truth serum, I hereby declare you, Mark, bisexual.”
Silence. Mark looked around the room, then down at himself. “Did it work?”
“I don’t know,” Gus said, “that’s a question only you can answer.”
But Mark didn’t feel any different. He always thought changing his sexuality would come with fireworks, images of big wet dicks flooding his mind, but none of that was the case. Instead, he found himself taking notice of different things. About Gus. The way his muscles got all sweaty and glistening in the heat of the sauna, the way his pecs heaved up and down as he breathed in the hot air, the way his trail of hair pointed down from his six pack abs to his…
“Oh—“ Mark stumbled back onto the bench. His dick was hard as steel, fighting to get out of his underwear. He looked up at Gus, almost as if for approval. He smiled, nodded, and Mark got to removing his briefs.
It was the first time Gus got to see the dick he had created. It flopped out of the black fabric, a tiny bit of pre cum flicking out onto Mark’s sweaty chest, and waved in the air, unbalanced by its own weight. And as he watched Mark start to play around with it, he felt his hand instinctively move down towards his crotch, where his own dick was starting to awaken.
“Fuuuuuck man,” Mark said as he continued to beat off. He closed his eyes, focusing on the pleasure while Gus removed his underwear and got on his knees. He didn’t notice the olympic athlete’s mouth above his cock until he felt something hot and wet swallow all 8 inches of his salty stick.
He opened his eyes. Gus Kenworthy was on all fours, chocking on his dick like a pro. Mark gasped. The image alone was enough to send him over the edge, but with the intuition of someone who’d been doing this a long time, Gus took the cock out of his mouth and stroked it, slowly.
“I got you pretty close, didn’t I?” Gus said, a little bit of cum dripping from his smiling mouth.
Mark could only nod. “I… I didn’t know liking guys could be this much fun.”
“Oh and it only get better,” Gus said. He grabbed Mark’s ass and flipped him over. Mark gasped. The strength with with Gus was able to maneuver him around was so hot, that he found himself flashing his hole even before Gus reared up behind him.
The heat was so intense, both from the sauna and from inside of him, that he found himself saying and doing things that he never thought. “Fuck me,” Mark whispered, shoving his ass up against Gus, and twitching as he felt the weight of his meat slap on his exposed hole.
But Gus wanted him to enjoy this. Instead of shoving it right in, he grinded his cock up against Mark’s crack, feeling the warmth in-between his cheeks, and letting his sweat and pre cum lube up his continually flashing hole.
This drove Mark nuts. Within moments, he was moaning, loudly, begging for Gus’ cock. So much so, that Gus was scared someone would walk in at that very second. He leaned down and whispered to Mark, “you ready for this dick?”
“Yes… yes…” Mark said in-between groans. Gus smiled, leaned back, and slid himself inside.
Mark screamed. He was tight as hell, which was to be expected. He’d never had anything up his ass before, but when the sharp feeling of pain had passed, a euphoria unlike anything he had ever experience swept over his body. Gus’ dick was so long, it went straight for his prostate. With every thrust, Mark felt himself grow hotter and hotter, the sweat coming off his his muscles in sheets.
“FUCK!” He was cumming. Already. They had been fucking for less than as minute when Mark’s cock started to spew seed all over the bench bellow. It just kept coming, the cum, and the sheer image of Mark creaming over his dick was more than enough to send Gus over the edge as well.
“Fuck I’m… I’m… UGGGGHHHHH!” Gus thrust forward, freezing as his body tensed and shot yet another load, this time straight down Mark’s formally straight hole. Mark could feel Gus tense and writhe behind him, his body slammed up against his ass and hamstrings, sending more warmth throughout his ever scorching body.
The orgasms lasted longer than the actual fucking, but once both boys were done, they flopped down on the bench, panting hard.
“Better than straight sex?” Gus asked.
Mark laughed. “I’ll tell you next time I see my girlfriend,” he said, and patted Gus on the leg. “Thank you,” he looked into his eyes, “for everything.”
Gus smiled, nodding to the door. “Want to watch me turn Stan into something crazy?”
“Oh yes.”
Frank checked his watch for the third time in an hour. The hands on the little metal face seemed to be crawling towards the “12:00,” and he knew when they did, he would finally be able to close the gym. Normally, most of the people left by 8:00, and he would get to close early, go out drinking with his friends, and relax at home with some Netflix. But tonight was different. Tonight, he had to stay ‘till the very last second because, remarkably, the gym wasn’t empty. Remarkably, Stan—or the aging bodybuilder who referred to himself as “Stan”—and Alex were still there, pounding out reps at the benches, feeling each other’s hot, sweaty muscles and exchanging long, impassioned kisses in between sets.
“Can we go home now?” Alex whimpered like a little girl. When he heard this, Frank sat up in his seat. Was this finally it?
“Just a few more sets,” Stan said patting his boyfriend, each one landing on Alex’s thick chest with a loud *thud. “I wanted that ass pumped and plump by the time we get to bed.” He slapped Alex’s butt. Frank rolled his eyes, leaning back in his chair and preparing for another half hour of gay smooching.
And that’s when he heard a voice come from the locker rooms. “HEY!” someone called. Frank looked up to see two new guys standing out overlooking the mat, eyes glued on Stan with righteous fury. Frank didn’t recognize either of them, and all he could think as they walked forward was: how the hell did they get in here?
Stan threw up his arms. “You boys wanna join the party?” he said with a jolly smile. But Blake—or Gus rather—was not smiling.
“Oh come on Stan,” Gus said, “don’t tell me you don’t recognize your own freshman year lab partner.”
Stan’s brain worked like molasses as he put all the pieces together. First Blake, then Gus, and now… the truth serum. He frantically patted around his pockets for the small green bottle, but then he realized he didn’t have any pockets; he was wearing nothing but a skimpy pair of briefs.
“Looking for this?” the guy next to Blake said, holding up the small bottle. Stan lunged forward and grabbed it out of his hand. He uncorked the top and put it to his lips. Nothing. He shook the bottle. It was empty.
“Look’s like your luck has run out Stan,” Gus said, “I took the last sip.”
Stan reached over and grabbed Alex’s wrist. “C’mon, let’s get out of here. Right now.” But Alex was transfixed on Gus’ body, lust burning at the corners of his gaze. “ALEX!”
“Alex,” Gus said, “don’t listen to that cranky old man. He’s not your boyfriend. I AM.”
In an instant, Alex pulled out of Stan’s vice grip and huddled behind Gus, feeling up his toned muscles and staring at Stan in fear and confusion. Suddenly, he was alone.
Stan dropped to his knees. “Please,” he pleaded with Gus, “just turn me back to normal. Please, I’ll be ugly again, I’m so sorry. Just make me normal.”
“I you will be normal,” Gus said, “in a few days, all of this will be just a strange bad dream. But until then, I think you’ve got to spend some time thinking about what you’ve done. And since you were so obsessed with getting into Alex’s pants, that’s where you’re going to spend it.”
Stan gasped. The air sucked right out of his lungs. He looked down to his chest to see that he was getting thinner. Flatter. He looked back up at Gus, a silent plea to reverse the transformation, but it was too late. He was shrinking down his face hollowing out and becoming white and silky.
His arms turned back and elastic, his legs sucking back up into his chest to form two large holes, and his back ballooning out into the shape of an ass, only to grow hollow and airy, just like the rest of him. By the time Alex removed his clothes and walked over to Stan, he was nothing but a pair of briefs, which Alex took and slid up his muscular legs.
Though he couldn’t express it verbally, Stan felt an inward feeling of euphoria as Alex’s cock filled up his face, as his pumped up ass pressed against his fabric. Though he knew it was only temporary, he also wouldn’t have minded becoming the hot personal trainer’s underwear. Permanently.
“How do I look?” Alex said, flexing and showing off to Gus, “I’ll let you do whatever you want with his body when we get home.”
Even as Gus imagined how amazing that would be, he knew exactly what he had to do. “Thanks Alex,” he said with a weary smile, “but I can’t. You’re going to go home. You’re going to go to bed, and you’re going to forget this day ever happened. I’ll see you for our training session next week.”
And with that, Alex put his clothes back on, and left.
Mark turned to Gus, mouth agape. “You just let him go?”
Gus picked up the empty bottle from the ground, fiddling with it in his hand. “I can’t have this much power,” he finally said, “nobody can. It’s not fair. It’s fun while it lasts, but you know better than anyone how dangerous it can be.”
Mark shuttered as he remembered all those months plastered onto John’s big sweaty body. “I suspect I’d enjoy it now that I like guys,” Mark said with a laugh, “but I get what you mean.”
They shared a moment of silence. After a minute or two, Gus said, “Alex is going to be pretty surprised when Stan randomly pops out of his drawers in a few days.”
“Yeah,” Mark laughed, “that’ll be something.”
“EXCUSE ME??” Frank called from behind the counter, “DO YOU SEE THAT CLOCK? 12:15. TIME. TO. LEAVE.”
As the two men made their way to the door, Mark turned to Gus and asked: “what are you going to do now?”
“Well, with a body this nice, I suspect anything I want. It shouldn’t be hard finding a real boyfriend at this rate.”
“Well maybe…” Mark stepped closer to him, “maybe you don’t have to.”
Gus looked confused. Then, he realized. “Don’t you have to find your girlfriend?”
Mark shrugged. “She’s probably found some other guy anyway. I know I have.” He smiled, and leaned in to kiss him. It was so passionate, so hot, that Gus could feel his dick sprinting up in his shorts. “Wow,” Mark said, feeling the Olympian’s dick through his pants, “someone’s excited.”
Gus winked. He took Mark’s hand, and they walked off together into the night.
“HELLO?” Frank called, “Anyone here?”
Mercifully, the locker room was empty. Finally, he thought, I can go home.
But just as he was walking out past the showers, he tripped on something. “Jesus!” he yelped, “what the fuck?” He looked down.
“These gay guys, I swear…” he reached town tenderly and picked up the long silicone dildo with two fingers. It wobbled seductively in his pinched grip.
Frank double checked to make sure the room was empty. When he was sure, he slipped it into his bag and rushed out of the room. No one needs to know, he thought.
Besides, it’s not like I’m going to actually use it… right?
