"I wish you would become a girl." The stone glowed and Jon felt his body change. He felt his hair getting longer and his body taking on a more feminine curvature. He helt his ass blow up a bit bigger and rounder. But the thing he noticed the most was his newly formed breasts, which he guessed were at least size C, pushing his shirt outward, making it tighter.
"I can't believe you just did that!" Jon yelled, in his new girl's voice.
Zoe only smiled. Michelle came in and took a look. "You look great as a girl, Jon."
"Huh? Were you spying on us?" Jon asked.
"Sorry. But I sure saw something no one would believe," Michelle said.
Jon was so wrapped up in talking with Michelle, that he didn't notice Zoe making more wishes, until she actually started to say things that diverted his attention.
"I wish that you wouldn't remember your name as Jon Alan Smith, but would remember it as Jenna Ellen Smith."
The stone glowed.
"Now, what's your name?"
Her new sister looked confused. "Jenna."
"Good. Now, Jenna. Take off those boy's clothes and put on some girl's clothes."
"Okay," she said cheerily. She walked over to her closet and began to get undressed. First came off the jeans. She admired her smooth hairless tanned legs. Second thing that came off was the T-shirt Jon was wearing. The shirt was so tight against her breasts that when she pulled it off, they bounced. As they did, she giggled. After she took off the rest of her clothes, she looked through the closet, completely naked.
Zoe and Michelle stared at her. They've seen themselves naked before and other girls in the locker room. But to see their own brother (correction: sister) with a sexy girl's body like that ... well, it was strange.
After looking through her closet, she turned around and said "I don't have anything to wear. These are all boy's clothes." But then she said "I don't know why I said that. Of course, they're boy's clothes. I used to be a boy." But for some reason, it was getting harder to remember that.
