Last summer I visited Morfa Dyffryn nude beach as I'd passed my driving test and was curious about being naked in public. I was 19 at the time and didn't have much sexual experience. I'd read about stuff happening in the dunes above the beach but it was quite quiet on the day I went. When I first got undressed I got an erection straight away but it did go down and I just sunbathed for a while. I then decided to go up into the dunes and walked for a bit. My dick was soft at the start but then I saw a man walking in my direction some distance away. As he got a bit closer I could see he had a hardon. This turned me on and I got an instant boner. I was nervous but excited and carried on walking towards him with my hard cock leading the way. The path was narrow so he waited for me to pass. I couldn't help take a look at his nice fat dick. I was pretty sure I was gay but hadn't done that much. He said hi and that it was a nice day and I agreed. He then said it looked like we were both enjoying our walk. he asked me how old I was and I told him I was 19. Both of us still had full boners. He then asked if he could touch my dick, I was nervous but I nodded. It felt good to have his hand wrap around my rock hard shaft and gently stroke it. I'm not sure how old he was but he looked about my dads age so maybe early 50s. I found it pretty hot that I was being wanked off by an older man I'd only just met. I took hold of his dick, it felt different to mine and was shorter but a lot thicker. He then moved behind me and pressed his body against mine, I could feel his dick against my arse cheeks which felt hot. I thought for a second he was going to fuck me which I wasn't ready for but he just rubbed against me while stroking me fast. I could feel myself getting close and said 'I think I'm gonna cum soon', he just said 'good lad, shoot your load for me'. About 10 seconds later I started spunking, it felt like it went on for ever and it felt amazing. He then got in front of me and wanked himself. I just stared at his dick and then he came on the sand. One shot actually got on my toes and his hot cum felt pretty nice on my skin. He said 'that was fun lad' and then we went our separate ways. When I got home I often used to wank off thinking about that experience, it was hot.
