By the time I was 13, I had been masturbating for over four years, but I didn't start to ejaculate until I was half way through my 12th year.
This happened on a Saturday morning when I knew I'd have the house to myself for four or five hours. I began by stripping naked, putting a towel on my bed, getting the vaseline out on the night table, and working up to a high horny state with porn magazines. When my dick was so hard it began to hurt, I took a gob of vaseline and spread it over my dick from top to bottom amd began a slow rhythmic stroke. When I felt the first twitch of an orgasm, I stopped, and watched my raging hard now red dick bounce up and down as kept pace with my heart beat. When I felt my hard begin to slack, I started jacking again, and repeated the edging two more times. When I began the fourth jacking, I felt my dick flex, and suddenly it was noticeably longer than before. This time I kept jacking until I was past the point of no return, and had a huge orgasm which felt as if it would never end. Later that day before I began the third session, I meassured my dick and found it to be six inches long. It had grown half an inch suddenly. If this has happened to anyone else, I'd like to hear about it.
