Michelle and her stepbrother, both bored and annoyed, resort to self-pleasure when left alone together. Michelle fingers her wet pussy and big ass in the bathroom, trying to be quiet. But her stepbrother catches her, and they argue heatedly. Later, they make amends and masturbate openly in front of each other, Michelle taking in her stepbrother's thick, straight, huge cock. She fantasizes about feeling that massive dick plunging into her tight cunt, just as someone enters, forcing them to abruptly end their erotic encounter.
