In this taboo tale, siblings Michelle and her brother find themselves alone, bored, and horny. Michelle retreats to the bathroom, fingers her wet pussy, and strokes her big ass, trying to be discreet. Her brother catches her mid-act, and they argue heatedly. Later, they make amends and decide to masturbate openly in front of each other. Michelle's eyes widen at the sight of her brother's thick, straight, massive cock. She fantasizes about feeling it plunge into her tight cunt, and just as they're about to act on their mutual desire, someone enters, forcing them to abruptly end their erotic encounter.
