Tension boils between step-siblings Michelle and her brother as they're stuck home alone. In separate rooms, they each seek relief, Michelle's fingers plunging into her wet pussy, her brother's hand stroking his thick, hard cock. Caught in the act, they argue, but later, Michelle approaches him, hungry for more. Naked, she takes in his massive cock, fantasizing about feeling it inside her. Just as they're about to give in, a voice echoes, 'What are you two doing?', forcing them apart.
