In a moment of unsupervised togetherness, a brother and sister, both teens, find themselves drawn to each other's bodies. She fingers her wet pussy, he strokes his thick cock, their eyes locked in mutual desire. Caught in the act, they argue, but soon, their lust overrides their anger. Naked, they masturbate openly, Michelle taking in her brother's massive cock, fantasizing about it inside her. Just as they're about to act on their urge, a sudden intrusion forces them apart.
