As Jon finished thrusting into Sarah, and climaxed, he started to feel ill.
"Oh my god," he panted, "I can't believe that I just fucked my sister - and that she did me up the ass. I think I'm going to puke."
"Your sister? What the hell? I don't even know you!" replied Sarah.
The strange goth guy looked at her, puzzled.
"I'm Sarah McMillan, hot stuff. And I don't know what happened with me doing you up the ass, but it felt good and my dick is gone. So, thanks for the fuck - now why do I look like a freak?"
Jon was flabbergasted. How could this be Sarah McMillan? He slowly realized that, somehow, Zoe must have swapped bodies with Sarah. And, apparently, all the girls in the school were still begging to have sex with him, even though he was in a different body - and since he had accidentally wished his old body to be a girl, that meant that Sarah was still going to beg to have sex with him.
Now he had to figure out how he could fix this mess. He was stuck in his sister's body, which had transformed to be a guy who looked a lot like him, but a bit younger, and gothic. Sarah was stuck in his old body, which looked like a slightly older version of Zoe, with a magic retractable penis. And Zoe was running around in Sarah McMillan's body. And, since the stone couldn't undo its own wishes, he wasn't sure if they could swap back without some really clever wording.
Jon pulled his panties up under his skirt, and picked up the stone. Thinking carefully, he said "I wish..."
