Discovered Wife’s Lust After Marriage

First it was about a year in when she had been away and when she got home we were all over each other. She was very wet and I was sure I wasn’t going to last long so I used a cucumber on her. She never batted an eye when I went for it. I have a tiny bit of girth but not a lot of length, this thin was more than an inch thicker than me and she orgasmed twice before I got on her sloppy pussy.
Then about a year goes by and a friend comes to visit. Bingo, she was obviously attracted to him and vice versa. We did some partying that stormy night and she had been crotch watching him all night. She started putting her tits on him and in just 30 seconds or so she had his jeans down exposing his semi erect at least I was hoping. It was bobbing up and down as she reached for it. They went at it all weekend and not long after he was back in town visiting a sick relative. They were at it again and once he moved back they had sex for over a year. He moved again and suddenly passed.
Our marriage goes on to this day. I knew after the first night it wasn’t going to stop, I couldn’t come close to taking her like he did. She was never difficult to orgasm but she could orgasm on him one after the other. The first night he came in her and he just kept fucking her until he came again.
