“Come on babe, keep going, one more for me” Brian pushed as Rob struggled to lift the bar above him.
“Damn that was hard, but that’s us done for today,” Rob struggled as he pushed the bar up and into the bench slots. He sat up and wiped down the bench.
“Well, I thought we did pretty well that today,” Brian said cheerfully.
“Could’ve been better, I totally messed up up the second set and I think I could have improved other times,” Rob moaned as the pair walked back to the changing rooms.
“Don’t say that you did really well. I think you’re just being too hard on yourself and…”
“I know how you look at Riley, I’ve seen you. He and Brandon are really good at working out, I know and you want to be like them. But they are grunts, their jobs require them to be healthy and fit,” Brian explained.
“Well I suppose that, and he has bouncier butt than you,” joked Rob. Brian laughed, they entered the changing rooms and began getting out towels for a quick shower. But before they could go into the shower area, two smart uniformed men strode into the room. Rob’s gaze quickly swung to the front guy’s perky butt, while Brian looked back knowing his boyfriend was distracted. It was Riley and Brandon, who were just about to start there session. Rob looked down at his bag now, looking impatient like he wanted to try something out.
“Come on babe, let’s go for a shower,” Brian asked, trying to pull Rob away. Rob came, but walked hastily to the showers and hid in a corner.
“What’s going on? First, you can’t control looking at his butt and now you want to hide,”
“I have something that might help us get ahead on working out,” Rob said.
“Oh god, you have a plan? Does it involve sex, again?” Brian joked.
“No, jerk! I was looking for anything to help us work out, but nothing much came up. Then I found this odd website. The site sold weird elixirs and potions…,”
“Oh god really, you were a top student at Uni and now you’re talking about elixirs?” Brian butted in.
“Brian, please listen, just for once,” Rob asked, Brian, nodded.
“One of the elixirs I found says it can give you the strength of anyone you want. All you have to do is wear something of their’s and then drink this elixir. Then it combines the strength of the person with the host. If we got a pair of Riley and Brandon’s spare briefs, we should be able to grow bodies like theirs,” Rob finished, showing off two glass bottles filled with red liquid. Brian pondered for a second. He didn’t really believe any of this would work, but maybe he should do it for Rob, and once it doesn’t work, he would forget about this.
“Ok then Rob, let’s do it,”
“Oh thank you, Brian,” Rob praised.
Rob took a peeked around the corner, the two marines were-almost-done changing. He saw Riley grind on Brandon in his underwear which turned Rob on. The two marines would play gay very often. Which Rob and Brian felt teased by, but they came to realise that it was only a joke. Riley and Brandon often talked about the chicks they banged or were interested in.
He gave a bottle to Brian, and they waited for the other pair to leave for their gym session. The gym was quiet today so they would have plenty of privacy while they grew the additional muscle.
With a loud slap on Brandon’s ass from Riley, the two walked out the door into the gym. Rob and Brian gave it a minute before quickly rushing over and skimming about lightly for a spare pair of undies they could use. Rob picked up a pair of Riley’s, and Brian got some of Brandon’s. They then quickly pulled them up. The briefs had plenty of sweat from each of the guys for them to absorb. Odd that they had multiple sets of sweaty clothing, guess that’s just the marine life.
They quickly returned to the showers, for more privacy. They found a couple of cubicles next to each other and pulled the doors shut on them so they could have some privacy.
“Ok then, On three we down it,” said Rob, Brian agreed, and the counted down, and as agreed they downed the red liquid on three. The liquid tasted bitter and had a disgusting aftertaste to it.
Rob felt his vision go blurry as the liquid seeped into his muscles. He felt as the briefs tightened around his waist and clung to him. He knew it was working now, his body would absorb Riley’s sweat, and he would gain Riley’s incredible muscles and body. He felt a jolt of energy go through him and then warmth spread throughout him. He felt a jolt in his butt, as his globes popped out as he gained the same perky butt like Riley. His legs and arms expanded with meat and muscle. His stomach hardened with muscle and a six-pack while his pecs grew into two boulders. He flexed as his bi’s and tri’s exploded out of his arms. He loved his new muscles and so began to feel them with his new enlarged hands.
The warmth moved up his neck before moving onto his head. Rob was slightly concerned by this, as he didn’t want his head or face to change, but he knew this was a part of the process. Plus, the elixir couldn’t completely change a person, just adjust certain aspects.
“Fuck this feels so good,” Rob moaned, his voice had changed slightly.
Rob became distracted from his changing body as he felt his average dick pulse with pleasure. He went to feel it through the fabric, with each pulse his dick became engorged, growing out until it was a mighty python that Brian would enjoy.
“Babe, I think we might have gone too far with this,” groaned Brian, in a new deeper voice. They both stepped out of the cubicles to look at each other. Rob was shocked and terrified when he saw Brian. He had completely-changed. His body had grown massively, just like Robs had. Brian’s face was squarer and also a bit duller now, compared to its lively, energetic feel before. His stubble had vanished, replaced with a soft, clean chin. His face looked far duller now too.
But Rob knew he had changed too. He ran to the mirrors and looked himself over, Rob’s face was far rounder and a little younger. His stubble had vanished to, leaving his face feeling smooth, But everything had been re-shaped. He and Brian were unrecognisable now.
“Holy shit, I wasn’t expecting this much change!” Rob cried out.
“We’ve got the bodies now, how do we stop this?” Brian continued.
“I’m not sure, maybe if we…” Rob tried to think, his mind was distracted by his hair changing from dark brown, to nice chestnut brown. He realised then that too much of Riley was being applied to him, the same went for Brian, except he was gaining Brandon’s features.
Rob moved his hand down to try and remove the underwear. But as his hand touched the fabric, his hand was repulsed as if two magnetic sides were repulsing each other. His hands seemingly moved by themselves afterwards. He saw as more of Riley’s features gradually appear on him, taking over and replacing anything of Rob. His mind was racing to fix this, but he didn’t know what to do. Pleasure began to spread from his groin and reach out all over him. His dick was leaking pre-cum and he had the urge to jerk off here and now, or fuck Brian. He shook those ideas off and tried again, but yet again the same ideas crept back in. The more he thought, the hornier he got. Unfortunately, he couldn’t quite get his undies off to jerk his dick or get Brian to help him out, so he tried whatever he could to release the pleasure in his groin. He started by trying to touch his new meat through the fabric.
Horny thoughts began infiltrating all parts of his mind, gradually twisting and removing his memories that he wouldn’t notice. His IQ dropped a little and then shot down. The changes began affecting more recent memories, suddenly he remembered being on a military base, going to strip clubs and being a marine. Rob began noticing the changes to recent memories but wasn’t able to focus as his body was intensely grinding the air. He couldn’t help himself but feel a need to do this, though he started smiling and laughing at his finding rather funny. Unsure as to what was happening he looked to his boyfriend, Brani. He too was humping the air, and looking rather happy at it. Royb wanted to ask him what was happening and why he was losing memory, but he couldn’t verbalise the words, instead, his horny mind began thinking about grinding his brofriend.
As he turned his hips to hump his brobe, Branli did as well. The two began humping each other for a while, but with each hump their attraction and horniness faded, becoming nothing but amusement to each other. The more Ryab looked at Bradli, the less attraction he had to him, instead he felt a great friendship and comradery towards him. His mind began bringing memories of the two in boot camp and becoming best bro’s there. As their attraction, to each other faded, so did their homosexuality. Their buttholes contracted, tightening hard so that no trace that either had ever been penetrated remained or any possibility of it could happen. Obviously, they sucked each other or jerked each other off, but that wasn’t gay, just dude stuff. They laughed more as they humped, thinking this more of a stupid game.
The briefs began to loosen around their waists, and their hands dived into grabbing their new meat. They aggressively began jerking their meat, which drained the remainder of their brains, old lives, and homosexuality, sucking them all into their big bloated balls.
“Can’t wait to get this big dick in some pussy,” Ryan cooed, as new thoughts of chicks projected themselves to the front of his mind, he couldn’t help but think about big boobs and hot chicks.
Ryan and Bradley continued jerking, the lives of the two gays were sucked down into the torrent of cum in their balls. Their minds began flashing before them, new memories setting in and piecing together their new lives. More flashes came in and new memories of fucking cheerleaders in high school and jerking off to hot chicks established their new firm heterosexuality.
Their movements got faster before they moaned…
“YEEEESSSS,” They both instantly came in their briefs, shooting out their old lives mixed with the rest of the potion. Their new lives were now set, though Ryan and Bradley wouldn’t care, as they had good times ahead.
There was a hard slap on Ryan’s new perky butt, and Bradley had an arm come round him as Brandon gave him a kiss on the cheek as a joke. The four laughed before getting changed back into uniform, Ryan and Bradley found that their old clothes and gym stuff had changed, then again they wouldn’t remember. They snapped a post-workout selfie and headed out.
