This is a true story that just happened.
I had just finished work and decided to go to a local gay bar for a quick beer. I had heard that sometimes one might find some fun downstairs, so beer in hand, I went into the basement to take a look.
There were a few guys down there, most in their 40's and 50's. I went to the toilets at the back and in a cubicle found there was a glory hole. When I saw a finger slid through the hole, beckoning me, I couldn't resist and I slid my cock through.
The guy on the other side of the glory hole was doing a really good job sucking my cock so I was thoroughly enjoying myself, when suddenly the door to my cubicle popped open. I assume I must not have locked properly. In any event, there stood a guy in his late 60's, maybe even early 70's, looking at me, my pants down at my ankles and my cock inserted into a glory hole.
He stepped into the cubicle and locked the door. Ordinarily I won't play with a guy so much older than my age, but I really didn't want to move as the guy sucking me was doing an amazing job, but when the older guy reached his hand between my legs and played with my balls, and after a minute or so, went down on his knees and began rimming my hole, I wasn't about to object. Moreover, the rim job he was giving my ass was amazing, and I went along with him when he produced some lube and pushed it into my ass.
At some point the guy who had been sucking me left off, but not to worry, another guy readily went down on me, even if, truth be told, he wasn't quite as good as the original sucker.
