1st time taking an older strangers coc in my mouth

The 1st time I got to suck a stranger was when I was young on a family road trip. We stopped off at a gas station off the highway so I could use the restroom. I had just finished peeing and was daydreaming as a guy came into the restroom as I walked up to the sink to wash my hands. I guess I had been standing there at the sink for a while, daydreaming, because the older guy peeing in the urinal next to me, said to me, “the hand towels are right there..” motioning to the towel dispenser on the wall. I grabbed a couple and glanced back over to say “thank you” like my parents taught me to say to adults. As I was wiping my hands on the paper towels I noticed the older gentleman had finished peeing and he was gently stroking his cock as he looked ahead and down at his cock that was beginning to get big & hard. I was immediately mesmerized, I had never seen a grown man stroke his cock in front of me before. I couldn’t take my eyes off of it. I knew, even without him looking at me, that he knew I was watching him stroke his cock, and he was getting turned on by me watching. After starring for some time watching him get almost fully erect, out of nowhere, and to my dismay, I boldly asked him if I could touch it. He looked at me, while still stroking his cock, by this time it was big and hard enough he could wrap his whole fist around it. He stared at me, then glanced at the door. I could tell he, like myself suddenly started thinking about what if someone came in? I motioned him to follow me into the only stall, that was next to the urinal, he did. There was no door on the stall so I knew if someone came in they might still figure out what we were doing but I was so overcome with lust after seeing this older man’s massive cock, I wanted to chance it. With my pants on, I sat on the toilet in the stall, as he entered the vicinity, and I became eye level with his massive cock. I nervously reached my hand out and gently wrapped my small hand around his shaft and began to stroke him. We both were very silent. After stroking him for a bit, I got up the court & asked him if I could put it in my mouth. He gently took the back of my head & guided it down on his cock. It was amazing. And fat, I had to really open my mouth to get his cock to fit. I could tell he was really excited now because he was super hard, he was fully swollen and I could feel the veins in his cock against my tongue. I was really enjoying this. We said nothing to each other as we were trying to be quiet so we could hear if anyone came into the small restroom. I could tell he was super turned on by how hard his cock was & I was super turned on, this guy was my dads age. Finally he said to me-“look up at me..” I slowly gazed my eyes up at him glancing up at him with his cock in my mouth, and that’s all it took, he came instantly, down my throat. He wanted to see my face as he came instantly my mouth. He withdrew his cock & zipped his pants. I figured I’d take this opportunity & asked him if he’d buy me a pack of cigarettes since I wasn’t near old enough to buy them for myself, he seemed a little hesitant but nodded & left the restroom. I stayed in the restroom knowing that if I walked out I would have to get back in the car with my parents & I didn’t want them seeing us taking to one & another. Just as I was sure he had left & decided not to buy my a pack, he came back in, set them down on the sink, as to not actually be handing them to me but to let me know they were for me and walked out. I quickly stashed them in my Jean pocket left and got back into the car with my parents. The hottest part, was as we pulled out of the gas station, I looked back and saw he had 2 sons my age with him in his car.
