"Okay," said Jon, "you beat me. Now let's figure out how to fix this before you have to go home."
Karyn laughed. "Look at the two of us. Here we are, plotting against the biggest assholes and bitches in the school, and all we've managed is to confuse our genitals."
"Your genitals may be confused," said Jon, "but I'm pretty sure I'm just a homely girl at this point."
"I wouldn't say homely," said Karyn. "You look kinda sexy to me..."
She moved towards Jon and gently fondled one of his nipples. She lowered her mouth onto his breast and sucked gently on his tit. Jon gasped as he felt a wave of pleasure run through his body, and his new pussy started to feel a little warm and moist.
Karyn reached down and gently pulled the tampon out of Jon's vagina. She looked at it and said "it doesn't look like you're bleeding right now... since I'm feeling horny, and I'm already wearing a condom, want to mess around before we set things straight?"
Jon answered by putting his hand up Karyn's shirt and fondling her boobs. Karyn smiled and started to stroke Jon's clit.
Jon found the experience strange but very pleasant. It was odd, moving around with the pendulous weight of breasts shifting on his chest, but Karyn seemed to know a few tricks that sent fire through his nipples and down to his crotch. His clitoris felt kind of like a tiny penis, only far more sensitive, and the feeling when Karyn shoved her warm, hard rod up inside him was like nothing he ever imagined.
Karyn was more turned on than she expected by Jon's pussy and tits. The contrast between these extremely feminine endowments and his otherwise masculine body was strangely erotic. She noticed that her new penis had taken the place of her clitoris, but otherwise her anatomy was the same. It was strange to have so much erotic feeling concentrated in one organ, but the release as she orgasmed was literally breathtaking. She fingered herself furiously as she rammed her cock into Jon again and again, and after she pulled her softening shaft out of him she was surprised at how much white, sticky semen was collected in the tip of her condom. She noticed that Jon wasn't finished as she pulled the wet latex off her dick, so she sucked his nipples and gently teased his clit until he came in a great, shuddering orgasm.
Jon and Karyn lay on his bed cuddling for a while before Karyn broached the subject of returning themselves to normal. Karyn was worried that her tampons and her birth control pills wouldn't remove her cock, since she still had a vagina, but ensuring that the switch was set to replace the equivalent items seemed to do the trick.
Jon's pussy was trickier, as putting the condoms through the funnel only returned his penis, but left him ball-less and with a very female vagina underneath. Digging out one of his old jock straps, however, did the trick. Jon thought his new cock was a bit bigger than before, but he didn't complain.
Jon's boobs were a different matter. Neither Jon nor Karyn could figure out what would replace the huge tits with a manly chest. Jon was starting to panic when Karyn decided to raid his sister, Zoe's room for an old training bra. This left Jon with tiny breast buds and a narrower chest than he would have liked, but at least he looked like a guy again, especially with a shirt on. Karyn took the opportunity to borrow one of Zoe's more recent bras, reducing her tremendous E-cups to a more familiar B-cup. Jon was disappointed with this, but chose not to comment, especially as he was still very aware of his sensitive female nipples.
