My first blowjob

I stopped at a parking lot for a short break and went to the restroom to pee. I was just about to finish when another man came inside, stood next to me, pulled out his dick and waited. At first I thought he had problems to pee so I said "takes time, huh?". He said "no, I am not here to pee, I am here for dick watching". How dares he, I thought, and said "okay, then I'll do the same" and looked provokingly at his dick. He was stroking it and it grew thicker and the glans was almost fully swallen. I could not help myself saying "it looks good". I was startled by my own comment and realized that my voice was shaking. I had never had any sexual contact to man before, not even talked to a man like that before. I did not know what to do. Thank God, at that moment the door opened and another man entered. We both left the restroom and I started heading towards my car, when I saw that the man turned around the corner, entered into a single toilett box next door and left the door a bit open. What can I say, I was drawn towards that door and without further thinking for one second I entered. The room was dirty and there was a strong urine smell... Too late to think, he locked the door, his dick was already exposed, larger and harder than before. I was hypnotised by this view, fell on my knees, and without the slightest hesitation started to lick and suck his cock! It just felt so great. I forgot everything around me. The first time I tasted a cock with my mouth and tongue. I sucked him until he exploded in my mouth. It was so warm and soft that I could not stop licking the wet glans. Eventually he pulled his cock away, pulled out a tissue, wiped the remaining cum from my lips and we left. He waved me a good bye, looking puzzeled, obviously still astonished about what had just happened. I was high for several hours afterwards...
