Bored siblings, Michelle and her brother, find themselves alone and horny. Michelle retreats to the bathroom, her fingers exploring her wet pussy, big ass shaking with each stroke. Her brother, overhearing, bursts in, catching her bare. They argue, but later, they decide to masturbate together. Michelle takes in her brother's thick, straight cock, fantasizing about it filling her tight cunt. Just as they're about to act, someone enters, forcing them to stop.
