Taboo siblings' hidden closet tryst

Bored and frustrated, a teen sister and brother turn to self-pleasure to pass the time alone. Michelle fingers her wet pussy and strokes her big ass, trying to be quiet. Caught in the act, they argue, but later 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. Just as they're about to act on their mutual yearning, someone enters, forcing them to abruptly end their erotic encounter.
