I realized I was gay at the tender age of 18. Strange how it happened, I had never thought about it or had any desires until one day.
My family lived in a decent part of town near a big city park. The end farthest from us was a busy amusement park with pool, tennis courts, basketball courts and all kind of things to do. It was an old park and probably a bit too large for the smallish city to maintain it all, so it had been decided several years before to let the west end return to a more natural state. That is where I loved to ride my bike.
After a while, I needed to pee and instead of riding home or all the way to the other end of the park, I remembered an old restroom I had seen on a trail I didn't go down often, so I headed that way. I rolled up and dropped my bike and ran into the restroom as I needed to pee really bad.
I stood at the urinal ripped open my jeans, pull my cock out and let piss fly. I really didn't realize how much I was moaning and carrying on until I heard it echo a bit, and laughed to myself. I hadn't heard anyone else come in, but suddenly there was a tall black man at the urinal next to me even though there were two more available. He moved in close and unzipped while I was still peeing, but for some reason, I was getting hard, so I stepped closer too so he wouldn't see.
I heard his piss hit the bottom of the urinal, and it sounded like a gusher, I figured he must have had to pee as badly as I did, and just about the time I glanced over to take a peek, he stepped back, and his huge cock came into view.
My eyes must have popped open wide and my jaw dropped! I can remember it like it was yesterday, that image is burned into my mind!
Suddenly it felt almost as if someone had kicked me in the balls, I know I grunted loud because I heard it echo off the tiled walls of the restroom, an orgasm of previously unknown force hit me suddenly, and I staggered back a step just in time to shoot a huge stream of cum onto the wall in front of me above the urinal! It was soon followed by a couple of more jets of equal force, but less volume!!
I heard him whistle and say, "Holy shit, that's a huge orgasm for a small guy! Were you jacking that thing?"
I couldn't talk, I could barely stand and just shook my head no. "You must have really liked seeing my big ol' dick then huh boy?" Still not able to talk, I shook my head and shrugged my shoulders as I damn near passed out!
The big man grabbed my shoulders as I started to crumble and kept me from hitting the floor. He led me toward one of the stalls and sat me down on the toilet and told me to take a couple of long, slow deep breaths.
I did as he said, and when my eyes focused again I realized that his huge black cock was still dangling out of his fly, and was swinging back and forth as he moved. Suddenly it was like I was hypnotized! I couldn't take my eyes off of it!
He reached out and ruffled my hair and said, "I think you are going to be alright now..." He turned to walk away and I managed my first word, "Wait!"
When he turned back toward me with his cock still swinging in the breeze he got a big wide grin on his face, "You want to touch it, boy?"
I slowly nodded my head yes and he moved his huge cock right in front of my face and I reached out my hand and gingerly touched his cock. Not only had I never seen a black cock before, I had never seen a cock that was uncut. I was curious, amazed and so fucking turned on and hard that my young dick hurt!
Over the next few minutes I had reached out and touched the huge dangling cock and he told me how to touch it to make it feel good. I was literally panting and for the first time in my life, I was so turned on, I felt precum dripping off my balls without touching my own cock.
