A few summers ago, my first wife and I would have her sister and boyfriend over for a cookout and pool party almost every week-end. Eventually, we would all get into the pool and start to play around and have fun. One night, my wife just took off her bathing suit top and dared her younger sister to take hers off also. Her sister quickly took her top off and to up the stakes a bit, removed her bottoms also. My wife was soon bottomless too.
Both of the girls now were daring the both of us guys to take off our bathing suits. Since I was enjoying seeing my wife and her sister naked, needless to say, my dick was very hard. I looked over at my sister in laws boyfriend, Greg, and saw that he was enjoying the show also. We both looked at each other and nodded and took off our bathing suits.
Now both of the girls were putting on a show for us by splashing around and telling us how good the water felt on their bare skin. My wife told me and Greg to sit on the edge of the pool so that she and her sister could compare our cocks and to see who was getting more excited. As I sat on the pool edge, I noticed that Greg had a very hard dick, that was standing straight up. Mine was also very hard, but was also dripping precum. Both of the girls sat on the other side of the pool and proceded to slowly rub thier nipples and to spread thier legs to give Greg and I a show. They told us to not touch ourselves, but just to watch. Their is a 5 year difference between my wife and her younger sister, but both of their titties look the same, with large brown nipples the size of small plates. Each of them were pinching their nipples and rubbing thier clits slowly. Both Greg and I were about ready to explode. I suggested to Greg that we needed to return the favor to the two girls and asked him if he would mind if I touched his cock. He grinned and nodded yes. I slowly started to stroke his hardon and both of the girls' eyes lite up.
My sister in law reached over and started to rub my wifes nipples as my wife suggested that perhaps a contest to see who came the quickest would be in order. She suggested that each of us could not masturbate ourshelves, but had to have the person next to them to it for them.
My cock quickly got even harder than it was and I could feel Greg's cock stiffen in my hand. Watching my wife and her sister fingering each other was one of the most exciting things I have ever seen. The fact that Greg and I were stroking each other off, only added to the excitement.
I could feel that Greg's cock was about to explode, with mine very close behind. He gushed a huge glob of cum, that went flying a few feet in the air. My cock quickly shot off also, and cum ran down Greg's hand. As I shoot off, both my wife and her sister were cumming at the same time, their fingers sliding furiously in each others cunts. Both of them just collapsed into each other, each of them panting like race horses at the end of a race.
All of us slid back into the cool pool water to rinse off. All of us felt like children who had just had the most intense fun of our lives, and started to make plans for this to be part of every week-end during the summer.
