My first time was a long time ago. I had just turned 18 in 1966 and had never done anything with men or women other than jerking myself off. I had for some years however been aware that in the washroom at the city hall there were lots of notices written on the stalls and walls asking for or offering blow jobs.
I went to the washroom one Saturday afternoon. That wasn't unusual because all the city buses were centred at the city hall parking area. When I got down the stairs to the john my heart started beating faster as it had for the several months whenever I got there. When I went in there were 3 men in the room which stunk of piss and smoke. I went to a urinal and proceeded to take a piss while trying to see what was going on without being obvious.
An older guy, probably about 45 took the urinal beside me and as I pissed it was obvious he was looking at my cock. Not sure what to do I just remained where I was and then noticed that he was actually stroking his cock. I looked at him and saw that he had seen me looking at his cock. He turned a little towards me so I could see him better and continued slowly stroking his now half hard cock.
My own cock started to stiffen all on it's own and I know I was blushing like crazy so I hurriedly stuffed it back into my pants and zipped up. I left the bathroom and went back up to the bus stop area.
The guy who had been beside me also came up out of the bathroom and walked over to me. He asked if I was heading to the south side of town as that was where the bus came for that area. I said yes and he offered me a ride. At that time hitch hiking was very common and so although I was pretty sure he wanted more than to just give me a ride I agreed to go with him.
