I see my wife having sex with young men and I like her

We met in 2001. We fell madly in love and were married 14 months later. During the honeymoon in Paris, I suggested that we go to a club that was only for married couples who slept with another married couple. It was always my dream! I was married before, but my ex-wife never considered it an option, and the woman I now have, thankfully, agreed.

First we put in a rule: We wouldn't touch anyone and vice versa. We'd just watch and let them see us. This went on for years until we found ourselves in the sex of three.

One night, we met a handsome young man, he was 20 years younger than we were. At first, he just wanted to talk. During the evening, I was with my wife on the pillow when she came to sit next to us. After a while, my wife surprised me by saying that she would like a threesome of it.

I was shocked, but I was thrilled at the same time. He offered her the most amazing orgasm she ever had. I realized he needed someone younger than me for a strong body that could give him what I couldn't.

Since then, we've met a lot of young men in a sex club. Sometimes during this moment I'm next to her, shake her hand or kiss her. Most of the time, I like to see it. I don't know what to think, but I know that I often get so excited when I see it with others.

Our relationship is even better because of this. We're closer than before and I love to see him get this kind of pleasure. This means nothing to anyone, but for us.
