You didn't know it but this position with your beautiful black wife is called "Yourself On A Shelf", who knew.
Anyway, she lovingly has her arms around you as you're holding her up with your cock drilling her pussy. Your friend Carl comes up from behind, you stop to keep your wife still so Carl can slide his dick into her ass. She even reaches around to make sure he goes in gently. Carl spreads her ass cheeks apart so both cocks have an unobstructed entrance and get the timing going, before both cocks unload their Caucasian Cum.
