With those boobs, the chick can only think about the balls in the nigger's pants and when he starts fucking her. For her, wiggling from underneath and taking her cheek is her life's work. Who wouldn't use a body like that, Boss? That's why he keeps her in front of his phallus.
Well, he fucked his sister in the mouth, as it should be, and by the looks of it, it's not the first time.
