I truly believe that many, if not most, women, including married ones, would love to show themselves naked to men other than their husbands, but are too embarrassed to admit it. There are a number of ways that we husbands can make it easier for them to let other men look at their tits and pussies.
One is by getting them to pose for nude photos, all the while assuring them that we would "Never" show them to anyone else. She will know, of course, that you are wanting them to show to other men with the words "look at my wife's Pussy!" but since she doesn't have to admit that, even to herself, she goes along with it.
Another is to let herself get into situations where someone can accidentally see her naked, or be able to spy on her. When other men are in the house, she can leave the bathroom door unlocked and wait for another guy to walk in on her while she is naked, then claim that she was "so embarrassed".
Or, she can undress with the window blinds open, knowing that some neighborhood guy will be outside and can look at her naked body for several minutes.
As the husband of women who have done these things, I know what a turn-on it can be to know that another man has seen my wife naked under these circumstances. In one case, a friend appologized at length for the fact that he had walked in on my wife and "got a look at her". I assured him that I was not angry, and that any normal guy would have taken the chance to "look at her". When he was sure that I was not upset with him, he relaxed and I was able to ask him "So, what did you think?"
He wound-up giving me a detailed description of my own wife's tits and pussy, enthusing over "all that hair on her cunt". He even said he wished that he was able to show His wife naked to Me. He admitted that, like me, he would love for other men to look at his wife's naked body.
Another way to get your wife naked before other men is to take her to a nudist club. you can always use the excuse of wanting to "relax" and get free of the restrictions of clothing. She may not say so, but she will know that you want to show her naked to other men. So, she may indulge you by going along and displaying her naked body for the other men who are there, saying without words "Go ahead and look,, fellows! My husband wants you to look at my tits and pussy!"
I, personally, have had all these experiences and a few more. I even once had a friend who asked me "Can I see your wife naked?" So I went to her and said "I want you to take your clothes off so Joe can look at your tits and pussy!" And would you believe, SHE DID IT!!
