A young couple living in the suburbs, the husband is tired from his long commute and has no energy at night. One day, the husband's older brother stays over, and the sexually frustrated wife of the younger brother is taken by him at night. The brother, excited by her body, thrusts into the resisting wife. Her body responds, convulsing and stifling her moans as she reaches a intense orgasm next to her husband. From that night on, the brother and sister-in-law secretly seek each other out. Their forbidden intercourse ignites them.
