The locker rattled and opened. Matt saw a hand reach in and grab him quickly. The zipper on his back was quickly drawn down to his buttcrack and Matt felt a breeze blow through him. He was held up by his shoulders and his head fell onto his chest. Matt couldn't see the face of the person who owned him, but he could see this guy, who he guessed was Sam, is naked. He was excited that he is finally going to be worn by someone well endowed. This guy manscapes too.
Matt heard a phone go off and he was dropped to the floor. "What? Yea I'll be there soon, wait for me. K. OK. Alright see you soon", Sam said as he hung up his phone. Matt's head was buried in his own thighs when he was hastily picked up. He saw the world upside down for a moment before he was shaken around, clearing the dust off his cloth body. As this guy started climbing into his zentai suit, Matt noticed he was doing it upside down. He felt hands enter his feet, and feet stretching out his arms. Matt was tickled as Sam put his head into his crotch, rubbing against his sensitive spandex. He had a sinister thought.
"Aww crap, how did I put it on upside down?" Sam exclaimed. "It's these stupid mittens." Matt got mad at the insult, and directed all his anger to the zipper, forcing it to zip all the way closed in an instant. "What the-" Sam started speaking, and fell over in confusion.
Matt could feel himself taking control of the suit while being worn. He outstretched his legs and arms and took a deep breath in. He tilted his neck left and right and reach up to rub his body. His face felt so good to touch. His fingers traced his lips, nose and hair that was slightly poking through the fabric. He reached down and touched his crotch, rubbing his hands over his newly formed cock and bulge.
Sam felt dizzy. He didn't know why everything looked upside down. He felt like his head was tucked inside a warm hoodie and he was drooling slightly. There was a salty taste on his tongue and his vision was obscured by a checkered pattern. He felt hands rubbing his cock through the fabric. He heard a moan that wasn't his and tried to look up and what made the noise. He felt blood flush his face, and when he peered hard through the fabric he finally saw the top half of his body inside the zentai suit rubbing it's own head. Sam realized he was his own cock! A hand reached down and started massaging him over the fabric.
Matt wondered if it was him controlling this body or something else. He was enjoying the feeling of being worn and thought it was him, but now he was moving without wanting to. He just wanted to continue to lay on the floor rubbing himself, but a jarring movement made him sit up. Matt continued to enjoy being filled by this entity and it stood up and put on Sam's cloths overtop of him. Matt shivered as he felt clothes cover his body, and wondered if he could ever bring Sam back by putting him on upside down...
Sam was terrified when his body stood up, but he couldn't help but wonder where it was going. His world was cast in darkness when his pants were pulled over his face. He could feel his heat filling the zentai underneath and this made him semi hard. A hand readjusted him and tucked him between his balls. He rubbed side to side as his body walked out of the locker room and into the world.
