Joan made her way back up stairs, as fast as she could without drawing attention to herself, cringing at the bouncing sensation in her chest with each step. When she got to her room she closed the door and locked it.
First she pulled out a box from the back of her wardrobe where she kept all her hidden stuff. She opened it and found that her stash of porn had changed from hot naked women to muscle men with huge cocks. She balked at the thought of it and then even more so at the pink dildo that was also there. Quickly she just grabbed the wishing stone and threw the box back in the cupboard.
Good, she thought, I've got the stone, but I don't want to make another mistake.
She looked at the clock next to her bed, School was over now and that means Karyn will be coming round soon, so Joan decided to put the stone on her desk and wait.
A few minutes later the door bell went and Joan was about to run downstairs when she realized that is was Mikey's... Michelle's ...friends, Peter and Tommy.
She waited another 15 minutes and was about to go phone Karyn when she heard a knock on the door. This time it was her.
"So you're a girl now." she said once she was in her room, "You've turned out quite pretty you know... More attractive than me, at least."
"Karyn! It was the wishing stone that done this!"
"What? You wished to be a girl?!"
"No! I wished for something interesting to happen and now I'm a girl!! It was an accident!"
Karyn staired for a moment and then started laughing.
