Lila went from being an ugly duckling to a fully-developed beauty over the summer. Her stepbrother, Allen, has noticed this and constantly tries to see more of her. But Lila is also getting attention from Allen's friends and, like a good stepbrother, is a bit weary of all these boys sniffing around. She confides in him that guys that used to make fun of her are now being super nice, but she doesn't know why. Allen tells her she has to learn that boys only want one thing - sex. Lila starts to suspect that her stepbrother wants the same thing, and maybe, she wants the same thing from him, too!
