I was left alone on Saturdays from eleven onwards for five or more hours. I got in my best jacking then.
By the time I was eleven, I had been jacking off for about two years. I couldn't ejaculate, didn't have pubic hair, did have good forceful orgasms, and my pecker had grown from a three inch hard to four and a half inches. On Saturday mornings, I could take my time with peter pulling, and spent five minutes or so admiring it before I got around to the serious business of jacking off.
As soon as I knew I was alone, I went to my room, stripped naked, stared at myself in the mirror on the inside of the door to my closet, and watched my hard dick begin to bounce up and down. During these preliminaries, my horniness went from hot to explosive, and I went from standing before the mirror to my bed. I lay down on my back, lubed up with baby oil, grasped the throbbing shaft in my fist, and began a slow stroke from the base up to and over the head. At first my grip was loose, my hand slid over my shaft and head without dragging the skin along with it.
After about five minutes, my penis began to get pink and the head red. As I got more excited, I'd fantasize about my after school sessions with my friend Alan, and the instruction I got from my older cousin who could ejaculate. By the ten minute mark, my penis was bright red, my balls retracted, and I was breathing heavily and beginning to sweat. My grip was now tight, the skin was being dragged along, and the foreskin being pulled over the rear of the head. I soon began to feel the start of an orgasm when I felt slight contractions in my pubic mound.
They got stronger and closer together, suddenly the sensation was so intense, I couldn't stop even if I had wanted to. Then I felt the first real spasm, then another, and they were followed by what felt like continuous ecstacy. I kept jacking with my butt off the bed, hips thrusting, until I couldn't stand it any more. and had to release my tingling dick. As I calmed down, I watched my firery dick begin to soften, even as it kept contracting with ever lessening spasms until I could relax and breathe normally. After a rest of 15 minutes, I did it again.
