Locked in the bathroom, Michelle turns the shower on, her hand slipping beneath her panties to stroke her clit. She leans against the wall, her breath hitching as she feels her orgasm building. Suddenly, the door bursts open, and her stepbrother stands there, shocked and aroused. He watches her, his cock tenting his shorts, as she tries to cover herself. Michelle, angry and embarrassed, yells at him, but the tension between them is palpable. Later, they find themselves alone again, the encounter lingering in their minds. Michelle, her pussy still throbbing, decides to masturbate openly, wanting her stepbrother to see her. He watches, his cock hard, as she fingers herself, her moans filling the room. Just as they're about to cross the line, a noise from outside startles them, breaking the moment.
