With a feat of strength that surprised both of them a bit Karyn pulled Jon onto the bed and rolled on top of him. The look of surprise on Jon's face made Karyn hesitate for a moment. Then he said, "Do it. I love you Karyn. Fuck me, I want to feel you inside of me." Karyn didn't need any more encouragement than that. She thrust her penis toward Jon's naked crotch, prepared to deflower her best friend and bring both of them untold pleasures.
Jon felt it a Karyn's penis slid between his borrowed labia and gasped in pleasure as he felt her sliding her penis up and down searching for the entrance to his vagina.
Karyn blamed her lack of experience and unfamiliarity with her new equipment for her not immediately impaling Jon with her penis; but, as the second passed and she still had no success she was beginning to think that something may be wrong. Just as she was about to pull back and take a new approach she felt something give and her penis slid into Jon.
"Ow, Ow ow! Get out of my ass! I didn't want you to put it there!" Jon screamed in pain and embarrassment.
Karyn had just pulled back and was about to push back in when he screamed. She pushed herself up on her hands and looked down at where their bodies met to see that she was indeed in Jon's ass. Confused since it had seemed to be the only opening she could find, she pulled out and sat up.
"Why did you stick it in my ass? I thought we were going to have regular sex?" Jon said his face turning red from a mix of embarrassment and anger.
"I'm sorry. I must have missed or something, it won't happen again let me just go wash this thing off and we'll try again. Okay?"
"Yeah ok, just be quick I can feel my arousal waning with each passing second."
"Well 'big boy' why don't you play with that cute little clitty of yours while I'm gone? Try it out, see what feels good. By the time our week is up you will be more familiar with what makes a woman's body feel good than any man on earth."
Karyn then slipped out the door hurrying to the bathroom just down the hall. She did her best to quickly clean off her burrowed penis before returning to Jon's room to find him laying on the bed, legs spread wide, hand buried in his crotch and with a look of puzzlement and concern on his face.
Jon looked up at Karyn as she came back in and asked her "Could you take a look at this? I may not have much experience with girls but I think there may be something wrong."
As Karyn climbed on the bed Jon pulled his hands away from his crotch so he wouldn't obstruct her view. She bent closer and looked at the genitals that had been her's less than an hour before, it was strange to see them from this angle to say the least. As far as she could tell just by looking at them they looked fine, but when she touched them and spread the labia she discovered something. She discovered why she had been having trouble finding Jon's vagina: he didn't have one. He obviously had her labia, her clitoris and he had obviously been quite wet earlier but it seemed that he didn't have a vagina.
Realizing what this probably meant Karyn lay back on the bed and spreading her legs reached down to feel around her groin. She quickly discovered that right between the base of her scrotum and her anus she still had an opening that could only be her vagina.
Jon saw what she was doing and was as surprised as she was that she still had a vagina and he didn't. "What the hell happened? I thought the wish would swap everything, why didn't it?"
"I don't know. Unless the stone used the narrowest definition of genitals to mean only the external reproductive organs, and even then I would think that would have included my vagina."
"That's just great, how are we going to have sex now?"
"Well I could do you up the ass again." Karyn said with a sadistic smile.
"Not a chance in hell girlfriend." Jon shot back.
"Then I guess there is only one thing to do." Karyn got off the bed and walked over to the pile of their discarded clothes, searching through them until she found the stone which she then held up in triumph. "We'll just fix this mess the same way it was created."
"Of course! I'm had this thing for over a week and still I sometimes forget about it."
"That's what I'm here for since I'll never forget it." She said hefting one of her wish enhanced breasts. "Now lets fix this and get the party started right this time. I wish..."
