Connor wandered around the department store for a while, until he found the underwear section. He decided that it would be fun to become a pair of underwear for a while. He noticed that there was a manikin in the men's fitting room, that wasn't wearing anything. Connor decided to become the mannequin. He grabbed the mannequin and put it in one of the rooms. He found an out of order sign behind the stand and put it by the door, so no one would disturb him during his transformation. He walked over to the stand, took his clothes off and placed his hand on the mannequin and felt the tingling feeling. He stood up on the stand and felt the changes begin.
It started with his feet. His toes seemed to harden and tan to be the perfect golden color. His toes began to form themselves into one appendage, though they still appeared to be separate. Connor felt his body hollow. His internal organs seemed to just disappear, although Connor was still alive. He realized he wasn't breathing, and then realized he no longer needed to.
Connor's legs began to harden and grow into muscular legs, which became plastic and hard. Connor watched as his member and his testicles flattened against his body. He groaned with pleasure as his penis grew into a large lump. Connor felt it with his hands, and felt a wave of pleasure. Connor's chest hardened. His nipples disappeared, and his pecs pushed out defining themselves. Connor looked down and saw that he had an eight pack. He was becoming one hot mannequin. Connor's arms formed into muscular model-like arms. His hair sucked into his body. Connor's face hardened into plastic. His eyes smoothed over, but somehow he could still see. His nose smoothed over, no longer having holes to breathe with. His mouth shut and sealed itself, his lips forming a smile. Connor's mannequin body tanned. The last traces of human skin were covered by his new plastic shell.
