Incestuous siblings' forbidden lust

Bored siblings, Michelle and her stepbrother, find themselves alone and horny. Michelle retreats to the bathroom, fingers her wet pussy, and strokes her big ass, trying to be discreet. Her stepbrother bursts in, catching her bare. They argue, and later, Michelle asks him to fuck her, leading to a heated, open masturbation session. Just as they're about to engage, someone enters, forcing them to abruptly stop.
