Tony swallowed the "Hot Gay Muscle Stud" powder all in one go. The taste was intense--sweet and pungent at the same time, like jockstrap mixed with fruit punch powder. He pulled a face, but then his jaw dropped as energy raced through his body, making every muscle tingle.
Tony's already fit gym-wrought body shook, his muscles trembling, tensing up under the skin, every separation suddenly showing, the veins rising under the skin, visibly pulsing. He let out a low groan of pain and pleasure as his muscles began to throb, inflating to get larger and larger. "Oh fuckkk..." he groaned, feeling strength surge through him. His shirt became snug around his growing torso, and his arms and shoulders filled the sleeves until they looked ready to burst. His jeans hugged his muscular ass and thick thighs, showing off the shape of his legs.
Ben's jaw dropped just a bit. He'd heard stories about this place, about how it had stuff that could *change* you. But he thought it was all bull. Now, looking at Tony, he knew better.
Ben reached down and picked up the empty packet that Tony had just used. "Hot Gay Muscle Stud" Ben read under his breath, his eyes widening a little. He looked up at Tony again, and saw that his frat bro was walking over to a mirror, admiring the changes the powder had wrought.
Tony turned from side to side, flexing and relaxing, admiring his new body from every angle while his dick slowly plumped in his tight jeans. Tony had always been well-hung, and his eight-incher was making its presence known in his pants. "Fuck this feels good," he announced to the room, as he bounced his pecs several times under the tight shirt. The fabric strained, having trouble keeping his bigger chest contained as it moved. Tony was turned on by his reflection, and eager to explore his body with another man. He turned away from the mirror with some regret, then shot Ben an intense, lust-filled stare, the corner of Tony's mouth turning up into a smirk.
