In a cramped, dimly lit bathroom, siblings Michelle and James find themselves in a taboo situation. Michelle, the older sister, has a secret. She's been selling her body for money, and now, she's brought a john home. James, innocent and unaware, walks in on the transaction, catching Michelle mid-negotiation. Money exchanges hands, and the john leaves, but not before asking James if he wants a turn with his "whore" of a sister. Michelle, livid and humiliated, lashes out at James, but the seed of curiosity has been planted. Later that night, after their parents have gone to bed, Michelle and James find themselves alone together. The tension is palpable, and the forbidden fruit of incest looms large in their minds.
