One time I accidentally walked in my mother-in-law while she was changing. It was in our house and it was in our bedroom. The door wasn't locked so I just walked in and found her in a fully nude state. I quickly left and she was pissed off I just walked in without knocking. I told her she should lock the door next time. She still thought it was my fault and said she would make me pay for it. Even my wife agreed with me but her mother said it is extremely embarrassing knowing I had seen her naked. I said it was only for a few seconds and not to worry. She said I wasn't the one exposed and I even offered to get naked for her. She then asked if being seen naked would bother me. I said it wouldn't and asked again if she wanted to see me naked. She said it wouldn't be appropriate but they asked again if I truly wouldn't mind being seen naked. I told her again it wouldn't and asked if she wanted to see me. She said maybe sometime but not now and told me to remember what I said. I told her I would remember and for her to let me know if she changed her mind.
A few months went by and she called to remind me how I said I wouldn't mind being seen naked; well now was the time for me to prove I meant it. I asked her where she wanted me to undress for her. She told me I already had and asked me to check my email. There was an email from her that had a link to a website. I clicked on the link which took me to pictures of me naked and even a video. She had planted a hidden camera in her bathroom and caught me changing into my swimsuit. The pictures captured pretty well ever inch on me including a semi-erection. I called her back and asked her to remove them. She said I told her I didn't mind being seen naked so now I was being seen naked by maybe a few people and they would probably only see me for a few seconds before looking at someone else. I told her I didn't mean having pictures of me put out on the internet. She replied it was my fault for not being clear on what I meant but for now they were staying up there. I told my wife and she thought it was funny and told me to not worry and let her have her way so we can get over this whole thing. The pictures got quite a few hits the first couple of days and soon hardly anyone was looking at them so I let it go.
I figured she was doing this because she was really embarrassed I saw her and it was her way of getting back at me. I sent her an email with some pictures of me in the nude but these were more graphic in nature to show I wasn't that embarrassed and just to get back at her and to annoy her. That didn't work out too well because she won that battle. I didn't expect her to do anything with the pictures but she posted them up on the website with the others and now everyone was seeing me showing off and doing some rather intimate things. My wife thought it was completely hilarious and she told me her mother always wins so I better just accept it. The hits on my pictures increased at the website and some wanted a video on me masturbating. My mother-in-law as joke asked me to send one so she could post it. She did add that she knew I wouldn't do it. I was getting pissed off at her and decided to push this battle with her so I recorded myself masturbating and sent it to her. She send me an email back and said she never expected I would do that. She said she couldn't bring herself to post it but then thought she had to give the people what they wanted. She told me check out the comments I received. I looked and she had put it up there. It was embarrassing realizing what I did but there were many comments that made me feel at ease and turned me on that I actually wanted to do more. When my wife found out I did this I didn't know how she would react. She found this even more hilarious and didn't seem to mind at all.
I began to realize I was a bit of an exhibitionist and if I did it through my mother-in-law my wife didn't seem to mind. I think she was getting off on showing her naked husband pictures and video to her friends.
We decided we would end this whole thing and my mother-in-law agreed. She did admit seeing me naked and doing what I did was very entertaining and it came in handy during her alone hours.
