Me and my wife went on vacation and we spent some time on a clothing optional beach. She only went topless but I actually took everything off. When we came back she talked to one of her friends about out trip and mentioned the clothing optional beach. Her friend was surprised we did that but was very surprised that I went fully nude on the beach. I was a little embarrassed with my wife mentioning it to her friend but figured that would be the end of it and seemed to be.

It was about a month and a half later when my wife had the computer on and was logged into her email. I saw some emails that were sent just after our trip between her and her friend. I probably shouldn't have been reading them but when I saw the subject line say "nude beach pics" it caught my attention. It was her friend and my wife talking about me on the beach. Her friend was making comments about my body and asking about things like how often I got waxed. There were even more comments and questions about me and even one specifically asking how big I was when I was hard. My wife's reply was that she had never measured it but I was at least average or slightly above average. She then said she wished she had a pic of me hard where she could see for herself. I then saw more emails with attachments that were pictures of me on the beach naked. In these emails my wife did say to just keep these to herself because I would kill her if I ever found out. Her friend replied she will because her husband would kill her if he ever knew she sent his pics to her last year. I started searching and found what she was talking about. Her friend had sent my wife pictures of their vacation last year and her husband was naked in them and to my pleasant surprise her friend was in one and she was naked too.

I didn't know how to best handle what I found so I confronted my wife about it. The next time her friend was over my wife told her what I found including what she sent my wife. She begged me not to tell her husband and I agreed not to if she stripped naked. She asked if I was serious and I didn't respond. She could tell I was and my wife called me an ass for asking her to do it. Her friend told my wife not to bother arguing with me as it was only fair I got to see her and she began to undress. My wife decided she would undress along with her. I wasn't complaining especially when I ended up with 2 naked women in front of me. My wife said if I was a man I would get undressed too so I did. There were the 3 of us naked. My wife was pissed at first but then suddenly began to laugh at what we just did which set all of us off laughing. We all got very playful and began to show off for each other. Soon it turned into a little more until the 3 of us were having sex. Once all was done we realized we may have gotten carried away. I think it wasn't sitting too well with my wife that I had put my cock into her friend but under the circumstances she said she would live with it. I guess her friend did get to see me with a hard on and also got to feel it inside her too.
