The first time I [M] got cucked

My wife and I had been married a couple years before it happened. I had a dream one night that I caught her in bed with another man and I woke up hard. I told her about this dream and she seemed intrigued but didn’t think anything of it. Over the next few months, I became fascinated with it and began to explore the idea. I bought her an 8” dildo and she loved it. Began to use it all the time. I’m 5” so 8” could do way more. My wife is 5’3 140lbs with a flat tummy,slim waist, and a big jiggly ass.

One drunken night, she confessed to me that she regretted not sleeping with this one mutual friend of ours, named Keith. Keith was a known player so she wasn’t interested when he tried to sweet talk her, before I came along. She knew he just wanted to sleep with her and nothing else. She later found out that he was very well endowed. I found this hot and told her we should name her dildo “Keith”. So she agreed to it. And so when I was using it on her or she would use it in front of me, she would moan his name and I’d cum so fast. I told her that if she ever got the chance I’d be okay with her sleeping with the actual Keith or at least letting him eat her out.
