"I wish that I can reverse this wish."
"I wish that I'm a girl but I still have the same personality I do as a guy."
With a flash Jon transformed.
Jon knew he was a girl now, and that her name was now Jonnie. She felt her chest expand, and realized she was wearing a bra... she'd have to wear one just as a matter of comfort. Jonnie reached to her head and half expected to feel long blonde hair, but of course she didn't have that. For one thing, her hair wasn't blonde and she hadn't wished for it to change. For another thing, since her personality didn't change, she wouldn't want long hair anyway. Looking around her room, she saw mostly the same things. There were a few dresses in the closet, but she obviously didn't wear them most of the time. The winter jacket Jon had gotten as a birthday gift last week, and left aside (since it wasn't time to use it yet) now had a tube of lipstick that also wasn't used--Jon nie had guessed that someone had tried to give her the lipstick and she had put it aside with the jacket.
Family pictures were slightly different, though not much--girls could wear jeans and T-shirts, after all. Jonnie went to her porn mags hidden under the bed--and they were still the same. She supposed she was a lesbian now.
Walking into the bathroom, Jonnie locked the door, and stripped in front of the mirror. It was Jon's body, but with a softer face, breasts, nicer curves, and female sex organs. She waved her hand and the naked girl in the mirror moved her hand.
What else would be different, thought Jonnie as she used the toiler sitting down? Well, though she had the same personality, people would treat her differently. For all she knew she could have a lesbian girlfriend. Perhaps when she worked washing dishes as a part time job last summer, she had been a waitress instead--not because her personality was different, but because a girl would be offered a different job. A few minutes later, Jonnie flushed the toilet and returned to her room to finish a video game--the saved game was exactly the same as before except she had named the character with a girl's name instead of a guy's. There wasn't much to do tonight, anyway; she'd see what was different tomorrow, with school and meals and talking to family and friends.
