Foster couldn't stop himself from returning to the gym. It felt like he could only live in its atmosphere, the sound machines running, weights hitting the racks, the smell of sweat-drenched clothes. He wanted to constantly soak it all in ever since the day he found the jock.
He could never take it off, the straps wrapping around his ass drenched in his sweat. It had appeared in the back of his locker one day, and something in the back of his mind forced him to try it on. Since then it was always around him. That's the only thing he seemed to remember right, everything else seeming to change afterwards. Something was happening, but he couldn't tell what.
Each time he looked into the mirror, Foster would expect to see something different, but it was always the same. He was older, the once full head of hair he was certain he had deserted and bald. It seemed to have moved down to the rest of his body, a thick beard dropping from his chin while a blanket of dark curls took over the rest. They covered faded tattoos he never remembered getting, his thick chest adorned with two rings through his nips.
The only thing that was constant was the faded jock wrapping his waist, his bulge growing larger from seeing himself in the mirror. Just like that his mind would fade as blood drained from it to his crotch, returning his focus to the workout he needed to do to further his transformation.
