Michelle, frustrated, begins to masturbate in the bathroom, her fingers plunging into her wet pussy. Her brother, overhearing her pleasure, bursts in, catching her naked and vulnerable. They argue, but the tension between them is palpable. Later, they make amends, masturbating openly in front of each other. Michelle's eyes widen as she takes in her brother's thick, straight cock, fantasizing about feeling it inside her. Just as they're about to give in to their mutual desire, someone enters, forcing them to abruptly end their erotic encounter.
