Every weekend I go for an early morning bicycle ride. I am out the door by 5:00am and am out for at least a couple of hours. I take a break at the mid point in an area that is pretty quiet and relaxing that is right by a lake. I have never seen anyone when I take my breaks but was surprised by an older woman one morning. She was in her early 60's and was just taking some early morning pictures with her camera. We began to talk and she asked if she could take some pictures of me by the lake. I normally don't like having my picture taken but she seemed like a sweet old lady and I saw no harm in it. I was just in my bicycle shorts and letting her take pictures of me. After about 10 minutes she asked for me to remove my shorts so we could do, as she put it, some more natural pictures. I told her I wasn't wearing underwear and replied that it wasn't an issues as she wanted everything off. I told her I didn't feel comfortable being photographed naked. She asked if it was because I didn't want my cock and balls exposed or was it my ass or both. I told her it was more my cock and balls. She asked if I would allow my bare ass to be photographed. I told her no one had ever asked and I was still unsure. She began to give me a talk about the human body and how it is used in art because it is so close to nature and there is nothing to be ashamed of exposing it. One thing led to another and I agreed to have my bare ass photographed. She promised to only photograph me from behind so I took off my shorts. She did get a peek at all of me but had me go out to the edge of the lake and look out as she took pictures of me from behind. She then had me lay face down on the sand and took more of me that way. I wasn't as uncomfortable as I thought I would be having her photograph me. She then asked for me to roll over and let her photograph my front. I hesitated for a few seconds but actually did it. I was now letting her get a full frontal of me. She then had me stand up and go out into the water all the while taking pictures. She then had me walk towards her as she photographed me more and was getting more full frontals. She had me lay back down on the sand face up and asked for me to grab myself. I did as she asked. She told me to relax and to slowly stroke myself. I was doing this as well and she asked for me to speed up the pace. I did and was getting close to something happening and she must have known because she told me to not stop or hold back and to just let it happen. There I was now cumming in front of her with her camera capturing it all. When I was done she thanked me for allowing her to photograph me and told me she better go. There I was thinking about what I had done and how someone had photos of me nude and masturbating.
I saw her the following week and asked what she did with the photos. She told me she showed some of her girlfriends. I asked for her to destroy them but all she did was laugh and told me she wasn't going to destroy anything where she had a guy naked and convinced him to cum for her. I asked how she would like it if someone photographed her naked doing that. She laughed again and said she wouldn't be stupid enough to do that. She left and said she won't forget what I did and will keep the pictures forever.
