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.

Fast forward to the summer of this same year. We have a get together at our house. Keith is there. Everyone is drinking and having fun on the back patio. After awhile it’s just the 3 of us there. I see the opportunity so I fake being sleepy and head to the bedroom. This next part is from her account.
They start talking about old times and how she never gave him a chance. Eventually she gets in his lap and they start making out and his hands are going under her shorts and grabbing her ass as she’s wearing a thong. She grabs his hand and leads him to the guest bedroom. She promises him that I’m passed out and that I won’t know.
He gets her into her thong and bra and lays her on the bed and starts kissing her body. Takes her bra off and then slides her thong off and starts eating her out. By this time, I can hear her moaning. I suck at eating pussy so she’s very happy. She cums and then he lays down on the bed while she starts sucking his 8” dick.
She then climbs on top and starts riding him and I can hear all the noises. Bed creaking and her moaning. He fucks her like that awhile and then puts her on all 4’s and starts fucking her doggy style. I’ve never heard the noises she’s making now at this point. Her screaming and moaning. His body slapping her fat ass. After about 15 minutes I hear him grunt and he explodes inside of her. I cum too as I hear this.

10 minutes later, she comes into our room. He’s gone. She’s still naked. She climbs on top of me and we start kissing and she slides my already hard dick into her and I can feel his cum leaking out onto me. She rides me for a couple minutes and then I cum in her too. Then we fell fast asleep and didn’t discuss until the next day.

Edit: my wife was 28 at the time.
