Boredom turns into desire as a brother and sister find themselves alone in the house. She fingers her wet pussy, her ass bouncing as she brings herself to the brink. He catches her, and instead of anger, they share a look of lust. Soon, they're naked, her eyes wide as she takes in his thick, straight cock. She asks him to fuck her, to fuck her hard, and he obliges, plunging into her tight cunt just as someone enters the room, forcing them to abruptly end their passionate encounter.
