Random Tales of Hookups Past #6 (First Gloryhole)

I was at the mall with some cousins and they wanted to get some lunch so I told them I would stay there and get some stuff I needed and so they left. I was real horny that day and took a pair of panties from one of the lingerie stores and took them to the restroom in the corner of the mall by the department stores to try them on. I went in the far stall and started playing with my self when I noticed the hole. Now I knew what a gloryhole was but never saw one live before. It turned me on so much but I doubted anyone would get in the stall next to me while I was in there let alone use the hole. Only a couple mins later the door opened and my heart started racing and unlike what I thought would happen a man went into the stall right next to me. I peaked threw and could see he was at least late 50s or early 60s, had some grey hairs and was fairly overweight. I was already turned on but when he pulled out his cock and started to piss I became rock hard and almost instinctively I put my fingers through the hole and held my breath. To my surprise when I pulled my fingers back he slipped his cock through still dripping piss from the tip and I couldn't believe it was real. I sucked him for about 3 or 4 mins before he blew what must have been at least a few day load straight down my throat and he even finished pissing in my mouth so I swallowed it all down and gave his head a kiss. He zipped up and got out of there real fast without even washing his hands. I just layed there on the floor of the mall restroom my face and shirt damp with piss and cum as I finished myself off quickly. Ive had plenty of gloryhole experiences since then but that was my first and I wonder if he has had any other occurrences with gloryholes or if that was his only time up until then or ever and most of all I wonder if it would turn him on to know the one who sucked him off that day was only 15 at the time.
