I suppose the best place to start is when I discovered public masturbation.
When I was a much younger man, I would head to a ball field that was a short bike ride from my home. It was on the edge of town and there weren’t many people that used it. It was surrounded by a wooded area that had some hiking paths that led down to a creek. Most days, I had the whole park to myself. I’d take my bat and a few balls and just take swings for awhile. Sometimes I’d head out on the trail and just sit by the creek for a bit. It was great because there was always someone at my house and I loved having a place that I could get a little privacy. There was an afternoon toward the end of summer while the water was still fairly warm that I ventured out into the creek. I had taken off my shirt while I was walking down and kicked off my shoes and socks before I went in. I was standing in the knee-high water when this feeling washed over me. I was just out in this creek in my shorts and underwear and wondered how it would feel to just be naked out there. No sooner than that thought had rushed in did I start to feel my dick stiffen. I made my way back to the bank and took a really hard look around. I hadn’t seen anyone the whole time I had been there and it was getting close to dinner time for most people. My heart was racing, my head was spinning from the adrenaline and my dick was harder than I had ever felt it before. After another paranoid scan of the area, I gulped and dropped my shorts and undies to my ankles. I was overcome with how good it felt and how excited I was. I stood there for a minute or two still paranoid that someone may emerge from the trail and catch me. But, as the time started to pass I got a little braver. I stepped out of my clothes and started to walk back toward the creek. The further I got from my clothes the more my head would swim with fear and excitement. Before long, I was out in the middle of the creek, completely naked, with the hardest boner I’d ever had. I could actually see my pulse in my dick. The idea that there was no logical explanation for why I was out in the middle of the creek with no clothes on and a raging hard-on had turned me on so much. I couldn’t resist pushing it a bit further. My hand made its way down to my shaft and I started stroking myself. My eyes darted around looking for any sign that someone was out there while I stood there stroking myself. It all felt so amazing. The fear and embarrassment of what would happen if I was to be caught was mixed up with the pleasure and hormones raging through me. It didn’t take long for the orgasm to start building up. My balls tightened and my legs started to tense. I tried to keep my eye on the banks, make sure I wasn’t about to be caught but the feeling started to wash over me. I knew I was only a stroke or two away from exploding. The paranoia snuck in at that moment and the sound of a twig snapping out in the woods somewhere almost snapped me back into reality but as I pulled my hand away the first rope of semen shot from my dick and it didn’t matter to me if I was about to caught. I latched back on to my dick and felt the greatest pleasure I had known up to that point. It felt like I couldn’t stop cumming. Each pulse of my orgasm made me moan. Every shot of cum felt like the first. It was amazing. I barely even registered that it had brought me to my knees. The cool water was gently washing the last few drops of cum off the tip of my cock. It took me a minute to gather myself and realize where I was and the fact that I was still naked out here. Fear rushed back in and I ran for the bank. I quickly got my clothes back on and started to search the area. It had probably been an animal that I’d heard earlier but I was convinced for a bit that I’d been caught. I made my way back to the field and never saw anyone. It wasn’t until I was back home that I’d managed to convince myself that I’d gotten away with it. I masturbated again in the shower just from thinking about how exciting it had been. I wondered if I could get away with it again. I also wondered what would have happened if someone had caught me. Would they have screamed, yelled at me? What if it was a cute girl? All of this started me thinking that, maybe next time, I might see how long I can get away with it. I might like getting caught.
