Dead tired from a long day, our petite, skinny teacher, Siri, crawls into the hotel bed of her client, Vincent, for a nap. Unaware of her new step-dad's presence, she's startled awake by his touch. Pretending to be a naughty student, Vincent teases her, and Siri plays along, their taboo roleplay heating up. She resists at first, but Vincent's persistence and her own growing desire win out. In the dim hotel room, they explore each other's bodies, their step-family fantasies becoming a reality.
