You chew on your pen, thinking about what to wish for. You ponder an idea you've had for a long time: a desire to experience life as a girl. And not just a normal one, a sexy one. It could be a lot of fun. Plus, if the note was right, everyone would accept you as having always been a girl, so you wouldn't be in any trouble.
You think about the best way to make this wish work. You're in the middle of class, and you don't want to draw attention to yourself. Maybe the class wouldn't notice, but you don't know the exact way in which you'd change. Maybe there'd be a bright light, or loud noises or something.
Besides, you'd like to savor the transition from male to female. That way you could take your time to get used to the changes. A drawn-out transformation would definitely work best.
Writing as carefully as you can to avoid spelling mistakes or using the wrong words, you create your wish.
"I wish that over the next hour, I will become the incredibly slutty and sexy girl known as 'Candi Cox'. I will have huge tits which everyone will remember me by, a nice butt and the best cock sucking lips in town, along with a nice long tongue. I wish I were a Hooter's waitress full time and that my uniform will be extremely tight, along with my shorts being spandex instead of what they are made of now."
You shake your wrist after writing it, being such a long paragraph. You're glad that it's just the beginning of class so you don't have to stand up and risk your erection being noticed.
