Michelle and her stepbrother, annoyed with each other, retreat to their rooms. Michelle, frustrated, starts masturbating, her moans escaping her lips. Her stepbrother, hearing her, bursts in, catching her naked and vulnerable. They argue, but the tension is palpable. Later, Michelle finds him masturbating in the bathroom. She joins him, their eyes meeting in the mirror. He slides into her from behind, her tight pussy enveloping his thick cock. They fuck hard and fast, their bodies slapping together, until they collapse, spent and panting.
