Danny dragged Jeff back home. Jeff was stunned at what had happened to him. "It's okay, Jeff!" Danny told him. "It's not THAT bad."
Jeff intended to refuse to shower or use the bathroom, but soon had to pee so bad his bladder was threatening to burst. He was forced to unzip the badly fitting jeans and look at his new penis: Danny's penis. It was normal, thank God, but a little shorter and thicker than his previous penis. He finished pissing and then managed to look into the mirror. Danny's face stared back at him. He hated Danny's face, Danny's fat belly, Danny's thick thighs, and Danny's height, but he was stuck with all of it.
A year later, Jeff had mostly gotten used to being trapped in Danny's body. He was starting to grow a bit of a mustache, which he shaved off. His big belly and man-boobs were disgusting at first, but as he got used to it, he realized it was easier to not have to worry about being healthy or fit. He could eat as much pasta and fried food as he wanted. He felt far more horny in Danny's body than he had previously, and he loved rubbing his thick foreskin over his fat stubby knob until it burst hot cum all over his big belly.
It didn't make a lot of sense, what Madame Illusia did. As a narrative it was fractured and confusing. But Jeff was glad she did. Spending the last year as a clone of Danny was the best thing that had ever happened to him.
