Michelle and her stepbrother find themselves alone, bored, and horny. She retreats to the bathroom, fingers her wet pussy, and strokes her big ass, trying to be quiet. He bursts in, catching her naked and vulnerable. They argue, but the tension's palpable. Later, they masturbate openly in front of each other, Michelle's eyes locked on his thick, straight cock. She fantasizes about feeling it inside her. Just as they're about to act on their mutual desire, someone enters, forcing them to abruptly end their intense encounter.
