Hello Chica,
Thank you for your inquirery about this matter. I applaud your interest in the subject.
I had an older brother who used to hide some rather innocent Playboy type magazines in his closet. Of course, being six years younger and age 10 or 11, I was just becoming aware of the feeling of excitement looking at a nude female. I would get a slight erection from the visual stimuli when I was bold enough to look at his wares when he was in school but I was at home. I would rub my penis a bit, but it did not go beyond that.
It was not until five years later, sitting in my room watching a sexy show of some sort on broadcast TV that something happened. I had no actual knowledge of what was about to occur, but as I became more excited at the girl in a miniskirt or bikini I was watching, and with my pants unzipped, and my dick out, I was getting stiffer, and oozing more clear slick fluid from my pee hole. I was amazed at how slippery it was.
I used the juice I was making to cover my penis with my thumb and index finger of my right hand making a circle and slide it up and down slowly. As I did so, I felt a very strange yet pleasurable tightening of the muscles between my balls and asshole. It was not maintaining, yet only getting stronger.
I continued this, aided by the view of the females on TV, for a while until the tightening became very, very intense. And then, moments later, contractions began and to my amazement, the creamiest whitest and biggest load I have ever experienced up to now came rushing out of my cock. It poured down around my fingers, and I was so alarmed at what I saw, I was almost scared. I wasn't sure what had happened. Although it felt very very good, I did not realize what I had done. I wasn't sure if I had hurt myself somehow or what this all meant. But I recalled other boys talking about orgasms and describing that juice comes out of your dick. I thought my oozing of the lube fluid was what they were talking about. In a little while, I realized finally what they had talked about was what had just happened to me.
I cannot recall how I cleaned myself up or if I left any evidence around that perhaps my mother would have seen. But I knew I had reached a milestone in my life. Now, so many years later, I only wish I could live that day again. And, without a doubt, I wish you, Chica, had been there with me.
