My wife and our close friends spent the weekend camping on the beach in separate cabanas. The park is public and very busy. There is a family area for cabins and an adults area with cabins, not a nude park. We had a long day on the water and returned to our cabin area to grill up dinner. After dinner, we just sat outside and talked, drank and enjoyed the warm evening. Our friends wife suggested that we play strip Uno and we all nervously agreed. We all started with the same amount of items on our bodies, but luck was on the girls side. If you win the hand, you get to choose who loses clothes. It was back and forth on losing clothing, more so against us husbands. My friend was down to his briefs after a number of hands, and lost them next hand. So, he takes a trip around the table and he’s naked sitting at the bench table across from me. The girls had lost their bottoms but both still had tops on and I had my bathing suit trunks. So, next hand, they target me. I lose and off comes my shorts and now I’m naked. If you get totally naked, you have to run a circle around the table for all to see. So there I go with my dick flopping all over the place. They wanted to call the game at that point and declare victory. I was dead set on winning one more hand and getting to see their tits. They were like you don’t have anything left to gamble with. I told everyone that even though I can’t get any more naked, there is however one thing I can do with a certain part of my body. For another round, I bet them that I would get an erection in front of them and let them watch me. Silence and awe is only how I can explain the moment. My friend was like what, and my wife and his wife didn’t believe I would. So I stood up from the table, my cock right in front of everyone and said my wager again. I couldn’t believe I suggested it. They agreed, and I wasn’t sure they would have, so it was like a dare now. I lost the next hand! Fuck! So they are all looking at me now and didn’t think I would do anything. I stood up, took a few shots, walked around to the side of the table where the ladies were sitting. The excitement was already making me hard, and I started rubbing and stroking myself. Everyone was just staring at me in amazement that I was even doing it. My friends wife said that she and my wife would take off their tops and show us their tits if her husband did the same. He’s pretty lit, so he stands up and comes over next to me. So there we are, naked and dicks in hand. He whispers to me that he wants to stun the ladies so he reaches down and grabs my cock. I did not expect that! He begins stroking me so I reach down and grab his cock and do the same. We were both rock hard in a matter of seconds and released each other. Two hard cocks sticking straight up in front of our wives. Man was it exhilarating. The girls are just staring at us, and we were looking at each other also. I really got pretty excited looking at and touching his cock. The girls jump up on the bench and off come their tops. Four gorgeous boobs and naked asses bouncing around in front of our boners was too much. I was about to come soon so I just jerked my cock and came right there in front of everyone. My friend did the same immediately after. We were all stunned at what had just taken place. I felt awesome! Never done anything remotely daring as that. We all looked at each other and sat back down and continued drinking. It was crazy and I still dream about that evening! My wife and I are really close to the other wife to this day - her husband was a jerk and divorced a few years later. We still visit each other when we’re near and talk about that night. I would love to be naked in front of them again and jerk off, or better yet, have them jerk me off. Good times…
