Bored and annoyed, step-siblings Michelle and her brother resort to self-pleasure to pass the time alone. Michelle fingers her wet pussy and big ass, trying to be quiet, but her brother catches her in the bathroom. They argue, but later make amends, openly masturbating in front of each other. Michelle takes in her brother's thick, straight, huge cock as he jerks off, fantasizing about feeling it inside her. Just as they're about to act on their mutual yearning, someone enters, forcing them to abruptly end their erotic encounter.
