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.
