Discovering the pleasure of frotting and cock suck

I was always been attracted to cocks, not men really, just sucking their cocks. But I hadn't had any experience until I was in my 40's, when I finally decided to seek out an understall rub as a first anon attempt at finding a cock to suck, after years of masturbating to understall and frotting videos. I had read about a washroom near my office, that was reported to be very active, I went on a Thursday afternoon. I wasn't misinformed I clearly walked in on a few guys sharing stalls. Unfortunately I got nervous, pretended to pee, tough when your cock is rock hard and left. I beat off a lot to that close experience - I realized I had to do it, so I went back on a Tuesday after lunch - very quiet, I hadn't thought about the time. Sat down in a stall, nervous with a lump of excitement in my throat. Eventually someone came in, used the sink I was convinced nothing was going to happen and was about to leave - the guy sat in the neighboring stall. I didn't really know how to proceed or signal, so I made sure my pants were noticeably low and stretched out my legs to suggest I wasn't using the facility. He put his foot practically into my stall, my cock jumped and before I could turn completely, there was a magnificent cock under the stall. Slide our heads together, moving closer together his rod slide against and twitched against my balls, was amazing - I thought I might explode at any moment. Then he stopped, stood up and left his stall. Knock knock, on my door, I opened it up and our cocks meet we toke turns manipulating our cocks. As they rubbed together I held and rubbed his balls, I was so hard I couldn't believe it - better than anything in the past and then I bent down and took his cock in my mouth. His cock twitched and grew as my tongue explored his beautiful mushroom head; the more his cock reacted in my mouth the hard and more pre-cum dripped from my cock. He pulled out and shot his load on my cock which he quickly bent down and sucked off, this caused me to cum harder than I had up to that point. We meet a few more times, at more private locations and each time my experiences expanded and grew in pleasure. I have ventured a little further in M2M, but nothing gets me more excited than feeling another cock pressed against mine. From that day, I still enjoy the anticipation of a cock being unveiled in front of my face and its first touch on my lips.
