Melvin frowned as he picked up the naked tanned bodysuit. There was no zipper or other visible opening. He pried open Chad's empty mouth and looked inside the empty suit. He flipped Chad over and spread Chad's butt cheeks.
"Hm?" Melvin said, as he stretched Chad's hole wider and wider first with fingers, and then hands. He grinned, and shoved his hands, arms and head between Chad's butt cheeks.
Oh, fuck no! thought Chad screaming in agony. This wasn't possible. He felt one of Melvin's shoulders and then the other. Melvin was climbing inside him.
Oh, crap, a naked nerd was climbing inside him.
Snap. Chad's hole closed up as Melvin's foot disappeared inside the suit.
Ow, ow, ow, ow, ow, ow,, moaned Chad silently as Melvin peered out of his eyes and walked with his feet in Chad's shins. He stopped in front of the mirror. He adjusted Chad until his toes tucked into Chad's toes. Chad's legs were all wrinkled like a rhino's or something. His belly sagged, as Melvin worked his penis inside of Chad's empty hose. He started jacking off to make his cock fit better.
"Oops!" said Melvin as he inadvertently blew his load. Instantly, the skin tightened around Melvin or rather Melvin grew to fit inside the Chad suit.
"Holy fuck, I look -" Melvin said, and added as he heard his voice change, "and sound just like Chad. I am Chad! It worked." He looked down at his leaking cock or rather at Chad's.
"Okay, so that's how I activate the suit. I wonder if that's how I deactivate the suit too? That could be a problem, if I blow my load and suddenly shrink out of Chad. I mean he's got a rep of fucking anything with boobs, and I was planning on carrying on that tradition. But, if-" Melvin was talking to himself, while feeling his - or rather Chad's- new muscles. It was fucking great to be a head taller. It all felt like him. He ran his fingers through his new curly blond hair. Eventually, he started to feel a chill, so he started to put on his clothes. He laughed at how ridiculous he looked with Melvin's clothes hanging awkwardly on Chad's body. He put on Chad's clothes, and grinned. Chad's smart phone chimed. He had a text.
