Would you let a man fuck your ass for your wife to watch?y

he has never expressed any attraction to men. He has done it solely for my enjoyment. He will get down there with me and kiss it and suck on it with me. But if move away he will too and not do it alone. Cum is no issue for him either as we love to cum kiss . I feel like him taking anal is a bridge too far for him. Although I would be ecstatic if he would.
He just needs to know how much it turns you on and you want it, and you want him to want it. The sound of you cumming while he is interacting with another guy will get him there.
