I remember the first time I saw my wife having sex with another man. First, let me give you an idea what she looked like and how much she loved showing off her body. She is 5'5" 120lbs. Blonde hair, perfect white teeth. 38D - 29 - 34 measurements. She had a boob job just before I met her. They were just stunning!
She always loved to dress in very revealing and sexy outfits and bikinis. Every vacation we went on she would dress even sluttier, which I loved! Her favorite thing to wear out were short, bodycon dresses. To add to the thrill, she usually did not wear a bra or panties.
A few years later, we split up. But we still saw each other weekly for sex. I drove over one night to stop by our house (I moved to an apartment) for a booty call. But there was another truck in the driveway. The house was on a large lot without neighbors on one side and fenced around the backyard and pool. I parked a mile away and walked to the back fence and peeked through a gap.
There she was in her tiniest thong bikini and was walking back and forth trying to get the spa jets working. I recognized the guy that was sitting down watching her prance around. He owned a restaurant we went to often. When she got the jets working, she took off her top and then her bottoms and asked him if he was getting in. He jumped up and took off his shorts. He was already hard. (mine was and is bigger I noticed happily!)
I was incredibly surprised that I was not angry. I found myself extremely excited to watch her! They sat on the edge of deck with just their feet in the spa. Immediately started kissing as I watched his hands feel every part of that body. Soon she got on her knees and started giving him a blow job. Between the pool and deck lights, I could see everything. Over the next 20-30 minutes they fucked and towards the end they were on the deck. She was on all fours and facing right at me. I was hard as a rock! I was carefully stroking my cock the whole time. He started moaning and going faster, I knew he was about to cum in her. I started cumming about the same time he did in my wife!
