Even though I’m bi, I don’t have a lot of experience with men (the older I get, the more I find myself leaning more toward men than women), but I’ve always been attracted to guys with dark hair and eyes. Needless to say, Latino men often fall into this category. 
One summer day about a year and a half ago, I was taking a walk in my local park. I live in Florida and it was about 90 degrees and breezy. I had my shirt off and decided to sit in one of the pavilions to rest. There were two guys at two other tables, a middle-aged white guy and a Latino guy a few years older than me (I was 30). I remember catching a glimpse of the Latino guy earlier and thinking he was kinda cute, but was trying not to stare. The middle-aged guy left a few minutes later after finishing his cigarette. Once he was gone, the Latino guy introduced himself and asked me my name. We shook hands. That’s when I got a good look at him. He was VERY handsome. He had brown eyes with a hint of gold, black hair and a neatly trimmed goatee and really nice smile with white teeth. He stood about 5’9” with a light to medium brown complexion and was thinner but with some decent muscle on him, particularly in his arms and chest. We made small talk from our respective tables before going back to looking at our phones. I kept noticing him stopping to look at me out of the corner of my eye. I kept doing the same to him. I could feel my dick getting gradually harder in my shorts, although there was not yet an obvious bulge.
After a few minutes, he got up to use the bathroom. I watched him walked toward the bathroom, checking out his cute buns. I waited a minute or two and realized that I had to take piss myself. I walked over to the restroom and open the door to find him standing shirtless in front of the mirror, stretching. He was smooth with a tiny patch of hair in the center of his pecs. His shoulders were broad and he was glistening with sweat.
Not wanting to miss this show but not wanting to be obvious, I quickly went to the urinal (which was in a tiny alcove and not visible from the sink) and went to wash my hands. He was standing right in front of the sink and stepped aside so I could get through. As I turned around, he said “Man, I just came from the gym and I think I pulled something in my shoulder ‘cause it’s sore right here.” He pointed to a spot near his right shoulder blade. I asked if he was okay, resisting the urge to rub his injury. He said he was fine and we went back to the pavilion. 
We continued the whole “staring at each other while isn’t looking” game for another twenty minutes or so. He never did put his shirt back on, so I got a nice long view of his sexy body. My dick was rock hard and trapped uncomfortably in my Speedo-style athletic briefs, which were soaked in sweat and precum. The tip of my foreskin, still damp with piss and precum, rubbed against my underwear. The friction was so intense at one point that I thought I was gonna cream my shorts. Finally, his phone finished charging and he said goodbye to me, giving me a fist bump before riding away on his bicycle. When I was sure he was gone, I pulled my shorts down slightly to look at my boner. There was a tiny puddle of precum welling in my foreskin. I immediately raced to the men’s room and went to the urinal. There was absolutely no one in the park at the time, so I dropped my shorts and briefs down to my ankles.
My dick was nearly 7 inches and my balls were tight. I immediately thought back to a little while earlier when he was flexing in the mirror. I imagined him working out at the gym and in the gym shower and began stroking. I wondered what his sweaty jockstrap smelled like. I thought about his his cute ass and switched from stroking to fucking my fist while cupping my aching nuts with my free hand. It only took about five minutes before I shot a couple of massive loads into the urinal, coating it with my man milk. Knowing no one else was around, I let out a satisfied “Oh, fuck yeah!” as my balls continued releasing my seed. When I finally could relax, I cleaned up and left.
I’ve seen the guy only twice after that. I work as a cashier and he came in twice to buy a soda (based on his work uniform, he looks like he does construction, which explains the sexy physique). Both times it was slow and he was the only customer. He remembered my name and fist bumped me both time, flashing that shy but sexy smile. 
TL/DR: I saw a hot Latino guy at the park, got blue balls, and jerked off in the men’s room when he left. Lol
