My wife and I are approaching our sixties although we’re told we don’t look anywhere near, and neither of us are in that bad shape. I work out quite regularly and she performs burlesque. We have been married for approaching forty years. I was a Virgin before I met her, and she had had sex just the once before she met me. Neither of us have ever been unfaithful in all our time together.

This year we went on holiday to a Greek island.

We like to go to nudist beaches for an overall tan and almost our first visit we had a beach walker (they parade the shoreline with semi erections to try and pick up partners), thinking he was hidden from us behind a boulder masturbate himself to orgasm while watching my wife practice her routines.

Half an hour later on the same beach, just around the other side of a large boulder where we were sun bathing, I saw from the sea a different beach walker was having sex with a woman while her partner sat at the side of them masturbating. People further down the beach were looking their way so it wasn’t a very private spectacle.

We left the beach and returned to the hotel where we had very hot sex ourselves.

My confession is that I would have loved for it to have been my wife who was being fucked. Now I find it hard to get this out of my head. While we have sex I love to watch her face, to see the pleasure build and overwhelm her, the effect her arousal has on her body. I find watching her masturbate an incredibly arousing experience. But the idea of someone else having sex with her simply blows my mind.

My wife though isn’t interested, although the fantasy does turn her on, she thinks some things should be left as a fantasy.

While I know she is right, the idea of someone seducing her after a burlesque show so that she has sex with them while I watch is my greatest fantasy which I have no hope of ever achieving.
