What are you doing?

The intense sensation cause Jon to snap back to reality. "Hey wait a second..."
"What's the matter?" Karyn asked innocently.
"You cheat. You made a wish when I wasn't paying attention. When we're relaxing I can't seem to disagree with anything you say or do, but that fades when I'm excited or mad. That's wrong. I can't believe you did this. I'm not some toy for you, when you can stop trying to manipulate me like one I'll be back." Jon got up and walked out of the room.
"Fine. I was just trying to have some fun with all that mochoism getting in the way. I really wish those ovaries of yours would hurry up and make the rest of you female so you can be more reasonable. Some times I just don't get men. The differance of a dick and some balls seems to make them into a completely alien race that only another dick can understand."
Karyn stopped glareing at the doorway and looked down at the dildo in her hand.
"Hmm, maybe I can gain some insights into men after all." Karyn held the dildo against her like it was the real thing and soon it merged into her body and was the real thing. "Oh this is weird, it feel so different. It's all out there, nothing hidden, just straight forward and in control." Karyn started to feel guilty about abusing Jon the way she had. What she had so calmly dismissed as machoism was his free will.
"Karyn!" Jon was screaming down the hall.
Karyn tried pulling the new appendage off but it wouldn't budge. She couldn't find a hidden catch or button to get it off. Then she remembered that when it was removed from Jon's crotch there had been that small mole on Jon that must have acted like the release switch. And it was still on Jon.
"Do you think this is funny?" He yelled from Just outside the door.
"Oh, he's already pissed. He'll absolutely kill me. I wish this thing would just disappear and I was back to myself." And suddenly her hands were empty. Karyn was now aware of the feeling of a hard lump under her back, and tried to think of what she might have done to Jon that made him this angry.
Jon Burst in the door and Karyn realised that not only had his genitals not returned to him but that he was now entirely female, with no signs of male in him anymore. She realised that she had wished he'd hurry up and become more female and it had happened but what was worse was she had wished away his genitals. Her breath caught as she realised the lump under her back was the stone.
"It was an accident Jon. I can fix it. Here's the stone I was lying on it and made a comment about not understanding because you weren't a girl. I'll fix it. I wish..."
