Our parents left for the day leaving you alone with your big boobilicious sister, who is looking sexier than ever. She notices you staring at her and to your surprise she seems into it. She catches you with a boner and invites you into her room…..the sex is so fucking hot but your sister pauses to tell you she has to pee, the passion is too hot to stop she lifts up off your cock to squirt her delicious pee all over your cock and continues to ride you, stopping at times to pee and squirt more of her yumminess all over you til finally she begs for a cream pie.
