My wife Cindys first gangbang

My wife Cindy is one of the most gorgeous women you can imagine. I met her when she was 17 and I was 24. She is petite barely five foot tall has dark brown hair a beautiful figure, and incredible sexy brown eyes. Everyone always thinks she is so innocent, and in fact she was a virgin when I met her, and until the events I am about to describe I was the first and only. She does however love anal sex although I doubt she would admit to it, usually she puts me there after long and heated sex when she is completely turned on. We had been together 7 years and had two children, when all this happened and part of me still is shocked. At the time I was working for the local university for a division that rents houses and apartments to college students, this job required me to be available on the weekends for maintenance calls.
Anyway after 4 years of child raising we were ready for a break and when my Mother asked if she could keep the kids for a week in July we were quite agreeable. We dropped off the kids on a Thursday and came home showered and then shaved each other’s pubic hair off. I love the feeling of hairless sex and we spent the rest of the evening having plenty. We took a break on Friday and made plans for a wild evening on Saturday. We spent Friday evening talking about our fantasies. I asked Cindy if she ever thought about sex with someone else and finally she admitted she did. I told her how I thought it would be hot. She told me there was no way I was having sex with another woman. Saturday morning I had to do some work and didn’t get home ‘til about 1PM and just as I put my arms around my wife the phone rang. It was work, one of the tenants had lost electrical power. Cindy suggested she just go with me so we could spend more time together. When we arrived at the house there seemed to be a party going on with about 7 or 8 guys hanging out drinking. They offered us drinks and I declined though Cindy immediately accepted a margarita. It took me about 1 hour in the basement to figure out the problem. By the time I got back upstairs Cindy was working on a third drink and flirting with all these 20 something year old boys in a way I never imagined, she seemed particularly fond of this one guy Trey who had dark skin hair and eyes.
