Tan gooey stuff? Well that's the color I remember my first cum being.
At the age of five I had discovered that it was quite pleasurable to lay on my stomach and gently rock from side to side. Obviously I didn't know at the time but the pleasurable yet tense feeling I would have after a few minutes was an orgasm.
When I was in the sixth grade the teacher had decided to show us a movie and he said we could sit anywhere we wanted but we just needed to be quiet and pay attention. If I remember correctly we watched a movie about World War II.
I ended up lying down in the front of the classroom with several other people watching the movie and as I had innocently done before I began to rock gently back and forth but this time after I tensed up I felt a warm slightly gooey substance filling up my underwear.
I immediately sat up and looked around and nobody noticed me so I walked to the back of the classroom to ask the teacher if I could use the restroom. When I was walking back I remember feeling this goo still pumping into my pants not for a long time but long enough for me especially since I didn't know what was happening.
The teacher let me use the restroom and when I went in I pulled my underwear down and this tan colored goo as I remember it sort of fell out onto my hand. I had no idea what it was and I wasn't sure if I wanted to know, I got some paper towels and stood at the urinal. I was standing at the urinal cleaning up and this younger boy I knew came in trying to talk to me and I was so nervous I yelled at him and told him in a most unkind way to leave me alone and he had a shocked look on his face and left. I later apologized but at that moment I was trying to figure out what happened and it wasn't until sex education started later that same year that I put two and two together.
