I think it's not about anything other than an inferior white male showing that he knows his place as an inferior... The point is use him or not... you are the superior Man, if you don't want to humiliate him that way there are a lot of other options, MAKE him clean her used pussy when you are done, Tell him to hand wash and wax your car while you take his wife, Go out with both of them and make him walk behind you and her, kissing and fondling her all night in front off him for the world to see...
