By the time I was 15 I had been jacking off for five years and ejaculating for two. I was at my horniest, and if I could have, I would have jacked off every hour. Saturdays were my big day because I was left alone for four or five hours in the morning.
Saturday morning was my big jack off day when I was 15. As soon as I knew I had the house to myself, I went to my room and stripped naked. First I measured my throbbing hard penis both for length and girth with a tape measure to see if it had grown bigger. It measured in at six inches long and six inches around, not bad. Next I lubed up with Vaseline, went into the bathroom and lay down on a towel placed on the floor. I had visions of my girl friend's size B tits, and jacked away. The first one usually lasted about five minutes, and when I came, I shot juice as high as my chin. After a rest of a few minutes while I had visions of going to the movies with my girl that evening where I could get my fingers in her wet pussy, I started jacking again. This time I could last as long as ten minutes. If I could, I tried to get in another two jacking sessions, but usually had to cut it off at three because my friends started cumming around about ten o'clock, and I didn't want them to catch me jacking off although they did more than once.
