Her stepbrother walks in on her, catching her in a compromising position. They argue, but eventually, they decide to masturbate openly in front of each other. Bare and vulnerable, Michelle watches her stepbrother stroke his thick, straight cock. She fantasizes about feeling it inside her, but their moment is cut short when someone enters, forcing them to abruptly stop.
