Bored and alone, Michelle and her stepbrother resort to masturbation to pass the time. Michelle fingers her wet pussy and strokes her big ass, trying to remain quiet. Caught off guard by her stepbrother bursting into the bathroom, they argue heatedly. Later, they make amends and masturbate openly in front of each other. 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 someone enters, forcing them to abruptly end their erotic encounter.
