Karyn thought of all the girls she knew.
There was Angie on the track team. She had nice muscle tone and good running form. Karyn thought about the few times she and Jon sat and watched the track team practice after school. Angie wasn't the fastest runner, but she seemed to love running like a cheetah. Even Jon pointed her out the first time, which is why Karyn had convinced him to watch them again and again.
Then there was Susie in Karyn's homeroom. She wasn't a particularly bright girl, but she had a body that Karyn would love to get acquainted with. Curves in all the right places, a pretty nice fashion sense for showing off her best features, and even Jon had commented about these things to Karyn once or twice. Karyn felt a twitch of arousal, but shook it off and continued to consider.
And of course, there was Jordan. After Jon had mentioned how Jordan had... "Wait a minute!"
Karyn realized that she kept coming back to Jon. "But he's a guy. As much as I like him, he has one of those... those things in his pants. Yuck."
"I'll be down in a few minutes, Karyn!"
Karyn picked up the note and re-read the warnings. "If he was a girl, I would sooo want him as my girlfriend. He's smart, funny, has beautiful eyes..."
She continued to think about Jon and then made a decision. Reality would change so that he's always been a girl, and it's not like being a girl is a bad thing. And since he'd be a lesbian and they were already good friends, he would... no, SHE would definitely want to be Karyn's girlfriend.
Jon spoke just then, startling Karyn. "So, what's up?" She hadn't heard him come downstairs while she was lost in thought, and she nearly jumped out of her skin.
"H-huh?"
"What's with you waking me up today?"
Karyn stood up and faced him. "Um..." She was suddenly torn. She wanted a little more time to think about what changes to make, besides his gender of course, but she had a perfect opportunity to do it right now.
