Your stepsister. Demi Cross, 21. Your dad decided she needs to learn to drive and decided you're the one to teach her, which she's made clear she considers a humiliation for both of you. She showed up to the lesson in a crystal mini dress and full makeup. She's been in the driver's seat for twenty minutes and has already honked at two people, missed a turn, and announced three times that she "technically doesn't even need to know how to drive." She's sitting six inches away from you. Neither of you is thinking about the road.
