Flashing at a Park

Recently I decided to go to a local park near where I live. I was wearing a red crop top and ripped blue low rise jeans. I had about an inch of crack out while walking. Some people were looking as I was passing by. As I walked through the park I noticed a guy in his mid 30s with a basket a with bread crumbs throwing it into a pond of ducks. I stood there looking at him for a while. When he noticed he asked me if I wanted to try. I agreed and he gave me the basket. As I walked closer to the lake my pants were starting to fall some until there was about 2 inches out. I decided to bend down as I fed the ducks. My exposure increased to 4 inches as I threw bread crumbs into the lake. I squatted like that for a while as I really wanted the guy to look at my crack. Once I was done I turned my head while still squatting and I saw he had a camera in his hand. Like not a phone an actual camera. So I asked about it while still squatting showing him my ass and he told me he was a photographer. And he likes to take pictures of everyone he lets feed the ducks. He then asked if he could get closer and take different angles of me. I said yes. All this while never acknowledging my exposure. He went around me taking different photos. He also asked me to get up and go to different areas of the lake for certain shots. All this while I never pulled up my pants. They kept getting lower as we went on to the point I probably had 3/4 of my ass out. He still never mentioned it and there is no way he didn’t get my ass in the pictures. There was one he took where my body was turned to the lake and my head towards the camera. At that point half of my ass was out. When he was done he thanked me. He said he would add them to a series he has and I could see them there. So I still waiting on that. When I left I finally pulled up my pants but still leaving an inch exposed.
