This was a few years ago, the wife and I went to Disney with another couple. Disney is a lot of fun with no kids to entertain.
After a full day of drinking and a really nice dinner we decided to hit the pool. It was slow to 10 at night so it was empty. We had a few more beers while we were hanging out. Both wives were wearing skimpy suits, and I caught myself staring at his wife and wondering what her small breasts would feel like.
My wife was a beautiful women with pretty good sized breasts, his wife was smaller with an athletic build.
At the end of the night both wives were sitting on laps and all of us were ready for some quality time. We headed back to the room, ( we were sharing a room) I made the joke about this reminding me of being in college.
It didn’t take long and we were both having having sex. I looked over and was watching his wife riding him. He was quick and I heard him say he was cumming.
