Michelle and her brother, isolated and bored, turn to self-pleasure to pass the time. Michelle fingers her wet pussy, trying to be quiet, but her brother catches her in the bathroom. They argue heatedly, but later, they make amends and decide to masturbate openly in front of each other. Naked, Michelle takes in her brother'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 someone enters, forcing them to abruptly end their erotic encounter.
