First time I saw a uncircumcised, non-white penis was when this asian or asian looking kid needed to take a leak bad enough that he hid behind some bushes and peed on a window that I happened to be looking through.
I was working as a janitor about 10 years ago and I was cleaning a small insurance office building and from the outside of the building if you were to look at the windows you would only see your reflection but from the inside you could see what was going on outside.
The building had these long vertical windows that went up almost the entire height of the building which was only one story.
I had been cleaning one night in the hall and when I came into the one of the offices I was startled to find a person at one of the windows. I realized it was an Asian kid, spikey haired, skater type about 14 he was behind the bushes but in front of the window. I walked up to tap on the window to scare him away, when he unzipped his pants and started peeing. I couldn't believe what I was seeing which was a full view of his uncircumcised asian cock which was darker than the rest of his body and his few short black pubes and urine gushing onto the window. For about 30 seconds I was inches away from his entire package and he didn't even know it. When he was gone I went around outside and tasted a small drop of the urine and then jacked off and felt like a creep for being so turned on but a few weeks later I saw the same kid skate boarding near the office and was turned on all over again not at him but at the event that had taken place weeks earlier.
