He’d been so focused on his bicep curls, that his six pack had already disappeared by the time he set down the weight, and went to flex at himself in the mirror. He realized the reflection seemed off, but it took him a moment, and another ten pounds gained, before he realized what was happening, lifted up his shirt, and nearly screamed in the middle of the gym floor.
What the fuck was happening to him? He grabbed the flab in his hands, just to see if it was real, and discovered that…he could feel it growing and expanding. He looked around in a panic, unable to understand how something like this could even be happening, and then he ran for the locker room. He had to get to a doctor or something, he had to figure out what was wrong with him!
But by the time he got to the locker room, his clothes no longer fit. The changes had accelerated, and he pulled on his jeans just in time to have the seams ripped apart my his expanding ass. He stared at his new, hairy body in the mirror hanging over the sink, disgusted with himself, when he noticed someone watching him with a smirk…someone…he thought he should be able to recognize.
It wasn’t until he was bent over the sink, the stranger’s cock buried in his fat ass, holding his hair back, filming the video to post later, and he realized it was Ian, a massively obese guy he’d bullied for years in college, now looking slim and trim after transferring all of his fat to his old bully, and taking his muscles for himself. He was nice enough to leave him some 4XL clothes once he was finished, but for his old bully, getting clothed was only the beginning of his problems. His hole was still itching for a cock…and if he didn’t find something to plug up there, he felt like he was going to go insane.
“Who’s the fat ass faggot now?” was all Ian said as he left the locker room, and the ex-jock to his new life.
