My wife is aware of my desire to share her with other men. I can tell that the idea of her having sex with another man, or being in a MMF with me and another man turns her on, but she won't admit to liking the idea.
Any time I bring up the idea, she giggles, and tells me that I certainly don't mean it and that it must simply be fantasy for me.
If you live in Bavaria (southern Germany), are at least 45 years old, and think you could successfully seduce my wife. Drop me a line.
