In a quiet house, Michelle and her stepbrother, Mason, find themselves alone and bored. Michelle retreats to the bathroom, masturbating softly, her fingers dancing on her wet pussy while she strokes her big ass. Mason bursts in, catching her mid-act. They argue, but later, they decide to masturbate openly in front of each other. Michelle's eyes widen as she sees Mason's thick, straight cock. Fantasizing about it inside her, she's about to act on her desire when someone enters, forcing them to stop.
