I am married too, to a wonderful wife. I just made a confession on 5-21-15 about the things my wife and I are into. Go up and read it. I want to tongue fuck her ass while she rides a big thick cock. I could never tell her this, but if that cock happened to pop out of her pussy, and into my mouth all covered with her juices, I'm afraid that I would have to finish it off for him. She might freak if she heard this, but it sounds like fun.
You only live once dude.
Don't downgrade your dreams to match your reality. Upgrade your faith to match your destiny.
I have told my wife. Shes OK with it the idea. But not into it. So the whole experience is lost. But I think I'm going to try this next month.
