Isolated siblings, Michelle and her brother, find themselves alone and horny. Michelle retreats to the bathroom, her fingers dancing over her clit, her mind filled with dirty thoughts. Her brother, overhearing her stifled moans, bursts in, catching her mid-act. They clash, but later, Michelle's curiosity gets the better of her. She watches him stroke his massive cock, her pussy throbbing with desire. "Fuck me," she begs, but a sudden noise forces them to abort their sinful encounter, leaving them breathless and aching.
