I was always very straitlaced when I was younger but in my mid 40s I started wondering about gay sex. I'd had a few experiences in cinemas and things where I realised afterwards that the guy had been sounding me out but I just hadn't realised at the time. I'd think about them and get hard and wonder if I was gay. I was able to find out quite a bit about the whole gay lifestyle online, and I discovered cottaging and gay cruising areas - at the time I was so naive I didn't know such things happened, I just hadn't thought about it I suppose. Anyway, I found out that there was a cruising area that was on my daily commute, I hummed and hah'ed about taking a look, but eventually went, nervous as hell, not sure what I should do or what the etiquette was. There was just a load of shifty looking men wandering about in the bushes as far as I could see. It was a wooded area, and there were some huge rhododendron bushes, thick foliage but with a hollow middle, I noticed there were a load of guys standing round one edge of a bush, so I edged closer for a look. They were at the entrance to the hollow part, in which i could see a guy bent over, trousers down, with another guy pumping him from behind, there were a couple of other men in there, they had their cocks out wanking and they were muttering at the couple fucking . I got a bit closer and noticed that all the others outside the bush were also wanking, some with their cocks out, others inside their trousers. I got so hard and my heart was pounding, but was so turned on I started kneading my own cock through my trousers. One of the guys saw me and whispered to me to show him my cock. I thought what the hell so I got my cock out and started wanking in front of him. He smiled and said nice cock and that was it, I started cumming like no tomorrow, practically turned my balls inside out, think I actually staggered a bit. When my heart got back to normal I got the post orgasm shame feelings, so i buttoned up and shot off as quickly as I could.
