Michelle and her stepbrother find themselves alone and horny, their arguments replaced by mutual desire. She fingers her wet pussy, trying to be quiet, but he catches her bare and vulnerable in the bathroom. They argue heatedly, Michelle calling their mother in anger, but later they make amends and decide to masturbate openly in front of each other. Naked, Michelle takes in her stepbrother's thick, straight, huge cock as he jerks off lustfully. Soon, 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.
