First of all, let me say that I love this site. Masturbation, private and public, solo and mutual, has been a big part of my life. I've been meaning to post a story for the longest time, but I never seemed to find the time. Once I did, I had a hard time deciding where to begin.
When I was in 5th grade, I guess that would make me 10 years old, we moved into a new house. It had shower sprayer, which I discovered quite accidentally felt awesome when I sprayed my cock. I had done a few other things up to that time like fucking my pillow, but this was different. This quickly became a daily ritual. While most mothers couldn't get their ten-year-old sons take shower enough, I practically lived in the bathroom.
I still had not discovered 'jacking off' in the traditional sense; that would come later. Plus, I still was not cumming.
About a year after I had discovered the joy of the shower sprayer, I found an old college textbook of my oldest sister's. It was on Human Sexuality. At first, I just wanted to look at the illustrations and photos. Then, like the true nerd I am, I started to read up on different subjects. One that caught my fancy was masturbation. This is the first place I ever heard about the standard method for male masturbation. It was also the first I had heard of something called an orgasm and semen. Still my understanding of these matters was purely academic.
I did, however, warm right up to the idea of jerking off. I remember waiting for the house to be empty and stripping down to nothing and beating off for hours until my cock hurt. Still, all this jerking and all the reading in the world didn't prepare me for the first time I had a wet orgasm. I was enjoying one of my hours-long jerking sessions. I must have been going at it for about 45 minutes, when my legs started to hurt. I sort of freaked out, but within a few seconds hot, runny, cum came squirting out of my little hairless pecker. It was awesome. I knew what had happened, but it still really took me aback. As much as I love cum, I miss those days before when I could going for hours and hours without it.
It would only be a few months before I would get to see someone else cum too, but that's another story?
