Bored and annoyed, an amateur step-siblings duo, Michelle and her brother, find themselves alone together. Michelle retreats to the bathroom, her fingers exploring her wet pussy and big ass, trying to be quiet. Caught in the act by her brother, they argue heatedly, but later, they make amends and openly masturbate in front of each other. Michelle's eyes widen at the sight of her brother's thick, straight, huge cock. Fantasizing about feeling it inside her, they're about to act on their mutual desire when someone enters, forcing them to abruptly stop.
