As a boy I was never instructed about sex, our family was very prudish, so when I came for the first time I was totally ignorant about what was happening.
I was sitting on the toilet trying to poop, and as a healthy eleven-year-old, I had matured early and had a good sized penis and quite a bush going, my penis was hard. I was having a hard time doing anything with my hard on and was flexing my ass, the flexing was feeling very good on my penis that was squished between my legs. I swear to this day I had no idea what I was doing only that it felt great.
The more I flexed my leg muscles the more my penis felt good. I adjusted the position my penis was in, leaving only my circumsized head showing from between my legs. Looking down at it the head was purple and throbbing. I flexed my leg muscle faster and faster then all of a sudden the most fantastic feeling came over me and white stuff started to shoot out of my penis. I was scared but fascinated at the same time. I dipped my fingers in the goo and tasted it.
So began a lifetime of masterbating and cum eating. Later that night in my bed I pulled my pyjamas and tighty whiteys down, pushed my hard cock between my legs and duplicated what I had done on the toilet, it was fantastic. I later learned I could do this anytime, anywhere, in class, in the back seat of our family car, cuming in my whiteys but that's another story along with how I shared my new found abilities with all my friends.
