Bored and alone, step-siblings Michelle and her brother resort to self-pleasure. Michelle's fingers dance on her wet pussy, her big ass jiggling with each thrust. Her brother, catching her in the act, joins in. They argue, but the tension turns into mutual masturbation. Michelle's eyes widen as she takes in her brother's thick, huge cock. She fantasizes about it filling her tight cunt, and just as they're about to act, someone enters, forcing them to abruptly halt their steamy encounter.
