The One & Only Time.......I think

Years ago we stayed in a Derby's Golf complex as a 40th birthday treat for my wife. My wife was a virgin when we met & it was her fantasy to have sex with a man or woman. I said we would arrange it one day. Then one weekend it happened. On the first evening after dinner we went into the bar which was very busy, lots more men  than women, mostly from golfing parties enjoying themselves.  Sat next to an all male party, one chap, late 20's took a shine to my wife and chatted to her more than me. She openly flirted with this lad. He asked me if he could dance with my wife and I agreed and during a slow dance he held my wife very close. I knew she was enjoying his attention & felt good that my wife could still attract a younger man. She told me he squeezed her bum and she felt his erection and he felt huge. I am only 5.1/2" hard. That night we had passionate sex. She admitted thinking of the lad as we were making love. The next night my wife insisted on sitting next to the lad again, they were going home the next day so I asked her if she wanted him to be the one she had sex with. She coyly said yes so I told her to set it up but she had to tell me all about it. I made an excuse that I didn't feel well and went to bed. The plan was for her to leave with me but she had told the lad to leave it 10 minutes and come to our room. I went in to another quiet bar and waited for her to ring me when the deed was done Off came the clothes and he picked up my wife and put her on the bed. He kissed all over her body & gave her a couple of orgasms before having full sex. The first time was over quickly and he came inside my wife. Afterwards they kissed and cuddled and she got him hard again. He was much bigger than me & she told me her fingers cound't fit fully around his penis. When his cock was fully inside her she felt it touch her cervix. Round two took longer and was more sensual with lots of kissing & he took her from behind, whilst standing up, her on top,  She orgasmed another couple of times having sex with the young stud until he ejaculated again with them both cumming at the same time. It was almost an hour before she rang me to come back to the room. Her lady parts were red and swollen and still leaking cum. I had sex with her cumming very quickly as I imagined them together. We often talk about that weekend and she never asked for a repeat. What she didn't tell me was he only lived 15 miles for our house in Nottingham and I can never be sure they didn't meet up again. I just had that feeling when I came home from work. I could smell the aroma of sex in our bedroom on a few occasions & just after her birthday she went on a hen night, she told me that anyway.  I just didn't ask. Maybe I didn't really want to know and now in our 60's she has never admitted meeting him again but I think she did.
