"I wish I had the body of Karyn."
Jon looked in the mirror and saw a girl with his face. It was feminine, but he could still tell that it was his face. The rest of him (or her) was definitely Karyn's, though. Especially the blond hair and big breasts that she had accidentally wished for earlier.
Jon walked around the bathroom and found it very annoying to have breasts, especially ones so big. Jon now knew why Karyn was so uncomfortable.
A knock on the bathroom door startled him out of his thoughts.
"Jen, can you get out of there. I need to use the bathroom." It was Zoe, Jon's sister.
Did she just call me Jen? Jon thought.
