Michelle, a curious and horny teen, is left alone with her stepbrother. Boredom leads to curiosity, and she starts touching herself, unaware he's watching. Caught in the act, she's embarrassed but aroused. They argue, but the tension's palpable. Later, she joins him in his room, and they openly masturbate, their eyes locked on each other's intimate parts. Just as they're about to cross the line, a knock at the door breaks the spell.
