Chad make a high pitched squeak. He felt Jim's slimy tight rosebud opening to admit his body. He felt it close tightly around his neck. Chad squirmed but he was solid rubber now, all he could do was squirm. Jim laughed. He stood in front of his bathroom mirror watching his naked body change. His hair was changing. It was getting curly and blonder, just like Chad's. He watched his face broaden and grow into a familar grinning face. He was Chad now! As long as Chad was trapped in his butt, he was Chad. He had the school rock star jock's life now. He could fuck any girl or guy in the school now.
"Everyone wants Chad inside them," he giggled in Chad's voice, "But I've got him inside me."
Chad was aware. He felt Jim's anus shifting around him. He feel the butt cheeks growing more muscular around his head. Suddenly, he was seeing through Jim's eyes. He could feel he was still trapped between the powerful butt cheeks, but he could see Jim's body reshaping into his own body. Weird, he was now trapped between his own butt cheeks.
Jim put on Chad's clothes that he had stolen, and headed to Chad's house.
"Where were you, Chad?" his mother asked.
"Spent the night at a friend's hope you don't mind," Jim said.
"Just call next time. I've kept your breakfast warm in the oven," she said, "And be sure to drink your orange juice. I already packed your suitcase, the coach wants you at the bus by 11 AM."
"11 AM, right?" Jim said. He narrowed his eyes and concentrated. He picked the right memories from Chad's brain. Aha, he said, "Yeah, the State Champions Awards Banquet in Capital City." He popped a boner, he'd get to share a room with some other football studs. Maybe tonight would be the night he'd get some action? Probably too soon.
He helped himself to waffles, eggs, and bacon that Chad's mother had prepared. He drank his orange juice like a dutiful son, and trotted upstairs. He changed into Chad's suit and tie, and brushed his teeth with Chad's toothbrush. That grossed Chad out, even if Jim's teeth were his now.
Then alone in Chad's bathroom, Jim dropped trou, and pulled Chad out. He watched as his clothing suddenly sagged around him. He walked over to the sink and washed Chad off. Then he sat down on Chad's toilet and took a stinky dump. Chad peered over the edge of the sink watching, but he couldn't raise his arms to pull himself out. He jumped up and down on his rubber feet. He really was in his own bathroom. If only his parents or brothers knew, they could help him. He made meeping noises, until Jim cranked Chad's phone's tunes to mask the noise. He cleaned himself up, and stood there with his pants down. He searched Chad's bathroom cupboard and medicine chest, and then selected a bottle of gel with which to lube Chad's body up, and then plunged him back between his butt cheeks. Chad was sputtering on the gel, as he returned to his new role as Jim's butt plug.
Jim enjoyed basking in Chad's glory, as he boarded and rode the bus to Capital City. He did find it a bit exhausting to keep clenching his butt to concentrate and extract Chad's memories. Rick was Rick, but Bill was Chunk, and there were so many other nicknames. He didn't realize Weasel the waterboy's sister was the hot cheerleader Meagan, but now he knew. He enjoyed the steak, peas and mash potato dinner, and graciously accepted Chad's award. He and the boys celebrated with beers afterward, and he staggered back to the hotel, and pass out naked in bed. His hand reached for his cock, and he jerked off thinking about the four other athletes in the suite, Chad was sharing a suite with Rick, Logan, and Tyrone.
The warm cum trickled down between his thighs and wells beneath his buttocks. Chad could taste it. He felt energized. He could move mofre. H pushed himself out of Jim's sleeping butt hole. The butt cheeks softened and flattened as Chad freed himself. Jim was now naked in Chad's bed. Chad needed to get help, but how? He was an eeping foot tall puppet boy now? Wait, he communicated with Jim when he was inside him. He would have to go inside one of his teammates for help.
