Once the pleasure became great enough, Karyn squirted into Jon's vagina.
Trying to catch her breath, while Jon did the same (through his nose), Karyn scooted backwards. She was deeply disgusted by what had just happened. But at least it was over. Her wish was for Jon to feel better and that had been accomplished. She looked down between her legs and saw that her penis was still there. She hoped that it might go away, but unfortunately it didn't. She was apparently stuck with it.
The stone was lying on the floor at that point. She picked it up and looked at it. It looked exactly like the stone Jon had gotten from his grandfather. It was the same stone. It had to be. So why was it doing this? Twisting their wishes into bizarrely erotic outcomes. Okay, maybe Karyn having a penis wasn't too bizarre. Some girls do have them (like transsexuals), but who has a vagina in place of their mouth? That's pretty disturbing, no doubt.
She had to communicate with Jon. But since he had no mouth, he obviously couldn't talk. But, he could still write.
She stood up and walked over to Jon's desk. On the way, her limp penis swung freely. She put her hand on it to steady it, but then immediately took her hand away. Ugh. I can't believe I just touched it, she thought.
She turned back towards Jon. "Jon? Can I ... borrow some underwear?" She never thought she'd ever ask him that.
Jon nodded and Karyn took out a pair of white briefs. Now that her new male member was under control (although, seeing that bulge still made her uncomfortable), she went to Jon's desk and got some paper and a pencil.
Then she sat down next to Jon and gave him the writing supplies.
"What should I do, Jon?"
She watched him take the pencil and start writing something down. Karyn hoped that through this whole ordeal, Jon had thought of a way to fix things. He was good with ideas. Given enough time, he could figure himself out of any situation.
Jon stopped writing and gave the paper to Karyn. It said:
Don't use the stone, Karyn.
"Well, yeah. That's obvious," Karyn said.
