Several years ago when I was in my twenties my wife's family and I were at their cottage for the summer. The crew consisted of my wife aged 21, her sister JoAnn aged 19, my wife's mother aged 40 and me.
On this particular weekend JoAnn had invited some friends up to stay with us. When I heard the news I couldn't wait to see these hard bodies. So, on Friday night three of her friends showed up ready to party. The first day was great, I sat in the cottage wanking my meat while watching six women sunbathing. At one point JoAnn came in the cottage and surprised me. I covered up fast and pretended to be watching TV but I wasn't sure if she knew what I was really up to. She just smiled and kept going, got what she needed and left. I then pulled out my cock and jerked it for all it was worth cumming in minutes.
I knew I was busted later in the day when my wife asked me if I was getting a good workout while watching TV. She said that JoAnn had told the rest of the girls and they all laughed and wanted to know more. She told them that she didn't see much this time, but that had previously watched me masturbate in the shower several times at her mother's house. My wife knows that I am an exhibitionist and has actually helped me set up situations where other women caught me wanking. It makes her horny when other women catch me and then she makes me masturbate for her.
So after dinner that night my mother-in-law asks me what I was doing this afternoon in the cottage? Nothing I replied. My wife said that everyone knew what I was doing and that they would like to see me jerk off right now in front of everyone. I agreed and removed my clothes. They asked me to stand on the coffee table so I did. It was a fantasy come true for me. Six beautiful women in bikinis watching me jerk off in front of them. My sister-in-law grabbed me by the balls and gave them a squeeze. Then again and again and then grabbed my cock and started jerking me. She was having a great time showing off for her friends when all of a sudden my mother-in-law moved up and put my cock in her hand and started jacking me off. Wow, it couldn't get any better than this I thought. But it did when JoAnn then took her turn and gave me a mind blowing jack-off, rubbing my cock against her smooth breasts.
For the next several hours the girls took turns jerking me off and playing with my balls. I came three or four more times and was exhausted. They also laughed and giggled as they teased me about my shaved penis and testicles and wished that their boyfriends would shave. This night was my wildest fantasy come true. To this day everyone has kept our little secret.
