I was on my way home from a few towns over from mine at night and i heard on the news on the radio there was an accident ahead and the highway is closed, i was close to a friend of mines so figured let me call and see if hes home i can grab us a bottle of wine and we can hang out a bit. He mentioned hes home with his wife they were going to have a night in the hot tub i can join them. I get there and realize i have no swim trunks, my friend is a lot chubbier than me so none he have will fit. He mentioned he has some older gym shorts that i can tighten the waist they should be good. I wore a pair and they were perfect. We went through the bottle of wine within an hour and chatted. I got up and asked to use the washroom i was sitting right in front of them both. With the wet gym shorts and nothing else under they were tightly attached to my bulge i have a decent size when soft. He was staring at it with his eyes open like he couldnt believe it, she didnt notice and pointed and explained where the washroom was and i went. When i came back i noticed that both of their bathing suits were hanging over the side and they said to me that its a nice night we should all try skinny dipping. I said sure that the gym shorts were uncomfortable when wet anyways and pulled them down and stood up to go in. They both were staring at it. He made a comment that he couldnt believe how large i was and he hadnt noticed until that day. I got back in and we continued to chat for a bit. After a while he asked his wife if she wanted to try something larger than his. She said she didnt know and was nervous. He said how about she compares our sizes and then sees how she feels. She said that sounds erotic. We both stood up in front of her and she held us side by side, i was semi erect probably 6.5inches or so and he was fully hard probably around 3 inches. She made a comment that im over twice his size and im not fully hard yet. She said lets do it. We went to their room and i fucked her for a few hours while he watched. We’re still friends today never told anyone else in our group and we have done it again quite a few times since always with the skinny dipping and size comparing in the hot tub.
