Bored and irritated with each other, Michelle and her stepbrother retreat to their rooms, only to find themselves drawn to self-pleasure. Michelle's moans escape as she fingers her wet pussy and strokes her big ass, while her stepbrother, overhearing, becomes aroused. Catching her naked in the bathroom, they argue, but later, Michelle propositions him. Naked, they masturbate openly, Michelle's gaze fixed on his thick, straight cock. As they're about to act on their mutual desire, someone enters, forcing them to abruptly stop.
