I got caught being a pervert
There is a place near where we live called Rooster Rock, it has a nude beach on the far end. I was sneaking away from my wife of a dozen years to check out the nude women, I especially like the far end where there are trees and bushes, nearly without fail a couple would be there, the wife with her legs wide open showing off.
My own wife is rather reserved, so while I would love it if she did something like that, I didn't have the courage to bring it up.
But then a girl friend of hers saw me out there, I didn't see her, but she told the wife. I got home and she began asking me what I was doing out there, so I was busted and I just told her I was sorry and wouldn't do that any more.
She floored me when she asked me why I never took her out there!
So, after some talk, we went as a couple, and out in the bushes alongside one of the trails, she stripped naked and spread her legs so that dozens of people saw her.
Now in the Summer we go out there several times, and my gal is quickly turning into a blatant exhibitionist. We have met several couples with like minds, and have had a few pretty wild parties at home.
In public, she is still reserved, but around friends and out there on the beach she is completely different.
We have never swapped or done anything other than dance with others while naked, which is a real kick. But I have a feeling we will swap one day if we find the right couple.
