This is my first story. It's a true story from a little over 20 years ago and I've had more experience since. I still get hard when I remember it happening. I hope you enjoy.

I think I must have been around 23/24 at the time. I'd had a long-term girlfriend I'd recently broken up with and had been spending a lot of time watching porn online. I became more and more interested in looking at the guys than the girls and started jacking off a lot to gay porn. Especially gay porn with fit older men in it. I was (and still am) really into watching guys in their 60s and above.
I discovered online that a beach not too far from me was used by naturists. One sunny Saturday I packed some stuff in a bag and headed there. My heart was racing at the thought of catching a glimpse of a nice old cock or two. I was only going to look though. I'd never fooled around with a guy and didn't really want to, I thought.
Anyway, I got there and went to the section I'd read was used by naturists and started walking through the dunes. It was pretty quiet. I only saw a handful of people (all men, mostly much older than me) hidden in the dunes. I couldn't get a good look at any of them apart from one very overweight guy who walked past me groping his cock and looking at me expectantly. I just said 'hi' and kept walking.
Eventually I thought 'this isn't as exciting as I thought it'd be' and found a quiet spot in the dunes far away from anyone else I'd seen, laid down my towel, stripped off and thought 'I'll just enjoy the sun on my naked body' and read for a while.
I must have fallen asleep because I was woken up by hearing someone say, 'that's a pretty sight'. Confused and not really sure where I was, I opened my eyes and saw a guy who I'd guess was in his mid-sixties standing a couple of metres from me. Apart from a baseball cap he was naked. I suddenly realised I had woken up with an erection, got flustered and tried to cover myself up. He just laughed and said, 'don't worry, I've seen plenty of those'.
