My wife is always willing to give me a blow job. Years ago she read a woman's magazine where they were discussing sex. It mentioned that a lot of men enjoyed their asshole being played with while getting a blow job. She tried it and it did feel better. Over many months it slowly progressed to her sliding a finger in me, to two fingers, to a tiny dildo and finally to a full sized dildo.. it just got better and better. One time after using a dildo on me she said the real thing would feel better. After much discussion with her telling me she would not mind it if I let a guy fuck me I decided to do it. She was right. It was more enjoyable. Much more. When I told her about it she wanted to hear all the details. She asked me if I had sucked his dick I replied I had not. She was greatly surprised and asked why not. I told her I was so interested in getting his dick into my ass I never thought about it. She told me I should try it, that I would probably enjoy that also. A week later I got together with the guy who fucked me and sucked his dick. At first it was strange but I quickly got into it. I did a lot like my wife does to me. I could tell when he was ready to cum and when he did I was hooked. I enjoyed the feeling of him cumming in my mouth and the taste was good. My wife was right again. When I told my wife she didn't say "I told you so", but did have a smug look on her face. She asked me if I was going to continue to have sex with my friend I said only if you don't mind. She doesn't so I have continued. My wife and I still have sex several times a week and I have sex with my friend at least once a week. She doesn't mind and refers to him as my boyfriend. Life is great.
