For us it is quite simple:
My wife told me that most men compliment her on her smooth shaved pussy.
She: "And I often tell them that it is your job to give them that pleasure, to give them that honor. You like I tell them, don't you?"
Indeed, I keep her pussy baby smooth for her. No, it is my wife who wants it.
After such a treatment she checks that I have done my job well.
As she strokes my hair, she sometimes tells me how happy the men will be with what I have done.
Sometimes she tells me how much she loves it when I shave her pussy to please other men.
But almost always I have to lick her to an orgasm afterwards.
Then she loves to give me instructions to give me a very good impression of what other men are doing.
I think there are very few men in "our" club who don't suck her pussy.
Sometimes she tells them that he is an expert. Loud enough for me to hear.
She never says another man is better than me.
After months she dared to tell me "the best I have ever had".
That doesn't make me jealous.
On the contrary, I like hearing that another man is obviously better than me because it encourages her to keep discovering.
