My Wife Had An Affair With Her Ex Boyfriend

I found out about the affair, two years after we were married. While we were dating we confessed things about our sexual past, kind of like a game when we were drinking one night. She confessed that he was the biggest she had ever been with. 8" and very thick. "S" told me that sex with him hurt her sometimes, but it was a good hurt. Fast forward, two years after our marriage. Her own sister spilled the beans during an argument with us. I was devastated. It took me a while to get over it. Apparently, she had been having sex with him for about four months. They had sex in his truck, in his apartment, and on the beach. My wife even confessed that while they were on the beach together, she begged him to come inside of her. Which apparently, he had been doing many times over the four months. Luckily she didn't get pregnant. That was six years ago. I'm now 45, S is 36, and K is 41. I actually find myself thinking about it pretty often these days. Part of me wishes she would rekindle the affair with him. Have sex with him on the beach again and let him come deep inside of her! I don't know why these urges are there. They just are. S, has no idea if feel this way. And I know K would definitely fuck her again if he had the opportunity. She's a petite blonde, 5 foot tall and 110 pounds. One of the things she admitted is that he loved, taking her from behind. And coming inside of her like that. That's what I frequently find myself thinking about...
