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 quiet. Her stepbrother bursts in, catching her mid-act. They argue, but later, they masturbate openly in front of each other, Michelle fantasizing about his thick, straight cock. Just as they're about to act on their mutual desire, someone enters, abruptly ending their intense encounter.
