Religious siblings' forbidden, cramped lust

Bored and annoyed with each other, a sister and brother resort to self-pleasure to pass the time alone together. Michelle fingers her wet pussy while stroking her big ass, trying to be quiet. Her stepbrother catches her and they argue heatedly, but later they make amends and 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. Soon, she fantasizes about feeling that massive dick plunging into her tight cunt. Just as they're about to act on their mutual yearning, someone enters, forcing them to abruptly end their erotic encounter.
