Boredom drives Michelle and her stepbrother to mutual masturbation, their session cut short by a sudden intrusion. Michelle's fingers dance over her clit and ass, her moans echoing through the bathroom. Her stepbrother, catching her mid-act, joins in, stroking his massive cock. They debate, argue, then make amends, deciding to openly pleasure themselves. Michelle's eyes widen at the sight of his throbbing erection, imagining it inside her. Just as they're about to connect, an unexpected visitor forces them to halt their steamy encounter.
