My sister is always asking me for favors but today she has a real one. Mansion tells me she has a date tonight with a black guy and she is afraid his big dick will hit her tight pussy, I think my sister is playing a trick on me but she was serious. I tell her I could possibly help her out long as she does not tell out parents, I feed my sister my huge cock letting her first suck on it then sliding my cock right in between her big natural tits. I let her ride my cock, but I wanna fuck her till she screams and moans for more than I fill up her tight pussy with my cum and watch it drip right out.
