Boredom turns to tension as stepsiblings Michelle and her brother find themselves alone. Michelle retreats to the bathroom, fingers her wet pussy, and strokes her big ass, trying to be quiet.

Fantasy takes over, and she imagines it plunging into her tight cunt. Just as they're about to act on their mutual desire, someone enters, forcing them to abruptly stop.
