Karyn's senses slowly come back to her as she realizes that she is holding the stone in her hands. Her eyes widen.
But since Karyn was part of Jon, Jon felt her excitement grow and knew that she was about to make a wish.
"I wish that.." She began.
"Karyn didn't mind being my hand!" Jon butted in. The rock glowed and the wish was granted. Even though Karyn started off the wish, she was part of Jon, so it could easily be considered that Jon both began and finished the wish.
Karyn grew mad, and Jon felt it. Using his "hand", Karyn threw the rock to the corner of the room so there couldn't be any accidents. "WHY DID YOU WISH THAT?" Jon's hand yelled at him. Karyn could remember her wish and knew that she didn't want that wish anymore, but she was still mad at Jon because he had stopped her.
"Karyn, you know wishes are permenant" cooed Jon. He came close to her and began to kiss her. "We may as well enjoy it." Jon felt her become arroused again.
Karyn knew that she should argue. She could argue that they could find some loophole. They could work their way around it, but she found that she didn't want to. It was nice the way it was. She could just relax and have Jon deal with her body while she still felt the pleasure.
