Alex found himself walking past a strange store he'd never seen before, 'Tagged' displayed across the entrance. It seemed to be an adult store, filled with clothes and items that bordered on kink. He couldn't help but find himself drawn in. As he looked over the items he managed to find some shirt that seemed to call to him, and shortly found himself in the fitting room changing into it.
As he let it drape over his shoulders he felt a strange tick at the back of his neck when it settled into place. He reached back, finding a tag there that he was sure hadn't been on the shirt. That was when he felt it in his skin. He pulled, the tag pulling his surface, and he began to panic. He turned around, seeing it with his own eyes attached to him.
Almost immediately he began to relax. It was almost like he'd been influenced, his emotions suddenly calm. He tried make sense of it, only to find those thoughts plucked from his mind leaving him struggling to remember what he'd just been thinking about. As he looked at himself in the mirror though, something else distracted him entirely.
He watched as his shoulders broadened, filling out his shirt. In moments his body quickly grew defined, his bulk increasing immensely as muscles filled out across his body. He struggled to comprehend the changes, watching his body swell in size and mass, his pants quickly ripping off as his lower half exploded in volume, leaving his thickened ass exposed wrapped in his jockstrap.
Despite his sudden increase in apparent strength, he realized he could no longer step back as if he no longer had control over his legs. His muscle felt like concrete set around him, trapping him, as if they weren't his. He struggled to raise his arms, bracing himself against the wall in hopes he could push himself away, but the second they were raised he found he could no longer move them either. That's when he felt the changes start in his head.
He stared at himself in the mirror, feeling bits and pieces of him pulled away from his memory. In moments he no longer recognized the face that stared back at him, watching its eyes slowly drain of any individuality. A droning buzz began to fill the void in his head, drowning out any thoughts he could have had with an oppressive stream. His mind fell silent, completely empty and receptive.
The door to the room unlocked behind him, followed by an employee with their supervisor. The employee looked at the tag, reading out 'muscle drone' from the description. The supervisor nodded, ordering their new product to the back to wait for a potential owner willing to buy.
