So this happened some time back but I still touch myself thinking about it. I am a regular in my neighborhoods r4r page but I didn’t realize people would recognize me in public as I don’t post my face. I had announced I’ll be going to a nude beach in the neighborhood but I guess people could tell from my ootd. There is a small hike to go to the beach. I was wearing a skirt with no panties and a crop top. While on a hike, there were multiple older people resting on the way down to the beach. As I was hiking down, I heard someone say my name and I was like who knows me here. I turned and saw an older man sitting on a rock. I went to say hi and he mentioned he was trying to talk to me and meet me for some time. As I went to him, he was very respectful and held me by my waist and mentioned I was pretty. It made me feel good. He slowly put his hands under my skirt and gave my buttcheek a soft touch. He asked if it was ok and I smiled at him. He had really big hands and my entire asscheek was in his hand. He started feeling my ass and I could feel his grip getting harder. He was fully groping me at this time. People were still walking past us but his hand was in my skirt. His fingers were now on my butthole and I could feel him pushing it in my ass. I was like omg his fingers are fat. He fingered me for sometime and I was leaking. There was a moment when his finger was in my ass while he had a full blown conversation with a passersby. I still regret not being able to share contacts with him. I got nervous and walked away. I still touch myself thinking about him.
