My ex wife was very modest, and very inhibited. One day a good friend of mine came by to swim in our pool. Our pool was private and not visible from the next door neighbors.
I had teased her for years about skinny dipping with guests, and she had always shut me off with a big "no way". I don't know what happened, but this day, when I suggested we skinny dip, she sighed, and said if I really wanted her to she would. I told my friend, and he and I both ******** nude. My wife was very reluctant but slowly removed her one piece conservative bathing suit. She stood in front of us, completely nude, the first time another man had seen her after 8 years of marriage. My friend could not help but stare at her 34D boobs, and furry *****. I was so turned on, and got an immediate erection. We all jumped in the pool. I loved the fact that my friend was seeing my wife naked. We played various pool games including swim through the tunnel. This entailed two people standing in line, with their legs spread and the third person swims through their legs. Then that person stands in front of the first person, and the back person swims to the front of the line between the legs of the other two, on and on. We all had on swim masks, and I knew my friend got a very clear look at my wife's ***** and *** as he swam between her legs.
We did this and other games for several hours, before starting the evening BBQ. I was sure my wife would cover up , but I was thrilled when she stayed nude for the rest of the evening, fixing food in the kitchen, getting drinks, and just hanging with us, all of us still completely nude. I know my friend enjoyed it as he got hard a few times during the evening. He got to see everything in detail. When it was time for him to leave, my wife gave him a long hug and a kiss, and they were front to front, nude, for about 10-15 seconds. When they separated he had a huge erection. She just smiled as he went to the bathroom to dress. As he left my wife was still nude as she showed him to the door. Afterwards we made hot love, and I told her how it turned me on to see her nude in front of him. We did it one more time before we moved out of the area.
