Bored siblings, Michelle and her brother, find themselves alone and horny. Michelle retreats to the bathroom, fingers her pussy, and strokes her big ass, trying to keep quiet. Her brother catches her, they argue, but later, they decide to masturbate openly in front of each other. Michelle takes in her brother's thick, straight, huge cock as he jerks off lustfully. She fantasizes about feeling that massive dick plunging into her tight cunt. Just as they're about to act on their mutual yearning, someone enters, forcing them to abruptly end their erotic encounter.
