Vaginae

"I wish that I had two vaginae, and that Jon was the right one and Karyn the left!" The stone glowed brightly, blinding Jon momentarily. His entire body went numb, and he passed out...
When he came to, he felt wrong. He felt like he was just a mouth, but without a jaw, tongue, or teeth, and positioned vertically. He remembered Sarah's wish, and realized to his horror that he must be her vagina! He tried to move, but only succeeded in wriggling his "lips".
"Ooh, feels like Jon just woke up!" came Sarah's booming voice, sounding far and distant. He saw a giant hand reach down and remove the garment that was obstructing his view, which turned out to be a pair of white cotton panties and a mini-skirt. He now had a clear view of Sarah's legs and below them, the ground. He wondered why he was slightly off-center, then realized that Karyn must be to his right. He winced, realizing she must be feeling just as terrified as himself.
"I bet you're wondering what you look like, aren't you? Well, let me show you!" Jon's viewpoint changed as Sarah plopped down onto her bed and spread her legs. She held up a small compact mirror so that Jon could see his new form. Reflected in the mirror was a woman's crotch, but with two vaginae next to one another. Above each was a patch of pubic hair; Jon surmised that the blonde one was Karyn, while the brown one was him. It was particularly degrading to see it right here in front of him; here he was, reduced to being part of someone else's body, particularly such an intimate one. He flexed his lips; the vagina in the mirror did the same. He and Karyn were truly together now, closer than any two people ever were, but they may as well have been millions of miles apart, for they could never speak. If he had eyes, Jon would have cried.
