vedio for curious wife

I have been trying for years to get my wife to cuck me.The closest we have come is role playing I try to take it any further she gets pissed. She has recently read a erotic book where they used porn to spice up there marriage,so she wants to try this I want to use this as an opportunity for her to view wives enjoying other men. Can anyone suggest a video that has a hot wife hooking up with another man that a women would enjoy.She prefers white so if possible a white bull with no offense just a husband watching his wife make love to another man????
