Bored siblings Michelle and her brother, both horny and fed up with each other, decide to masturbate together, thinking they're alone. Michelle fingers her wet pussy, trying to be quiet, but her brother catches her. They argue, but later, they make amends and masturbate openly in front of each other. Michelle, seeing her brother's thick cock, fantasizes about it inside her. Just as they're about to act, someone enters, forcing them to stop.
