Bored and frustrated teen siblings, Michelle and her stepbrother, find themselves alone together. Michelle retreats to the bathroom, fingers her wet pussy, and strokes her big ass, trying to be quiet. Her stepbrother walks in, catching her naked and vulnerable. They argue, but later, they decide to masturbate openly in front of each other. Michelle's eyes widen as she takes in her stepbrother's thick, straight, huge cock. She fantasizes about feeling it inside her tight cunt. Just as they're about to act on their mutual yearning, someone enters, forcing them to abruptly end their erotic encounter.
