I am 24 now, and this story took place when I was in 4th grade. I was 11 I think, maybe 12. I had started puberty; my dick was probably about five inches or so and I had some hair around my dick and balls and a little on my armpits. Not bad for a geek in 4th grade, huh?
Anyway, I shared a room with my 9-year-old brother. We had bunkbeds-he had the top bunk and I had the bottom bunk. One night while lying in bed just after we turned the lights out, I began to get really hard. I was remembering what they told us in school not too long ago about puberty and hard-ons and masturbating. 'This must be it,' I thought. So I pulled the covers and my underwear down to my ankles. Using just the moonlight, I saw my dick hard for the first time. I touched the head lightly. It felt great. It was sooo sensitive and felt sooo good.
It only got me harder. I don't remember how, but I began to rub my right thumb on my dick, just below the head. Needless to say, this produced a sensation I had never felt before. I loved it and kept going. Soon I had the most increadible feeling start to build up inside me. It felt soo good I couldn't stop. I kept going and had my very first orgasm. Just with my thumb! I still can't believe it today when I think about it. I had cum on my pubic hair and my stomach. It wasn't much or very thick as I remember, but I came.
I remember thinking to myself, with my softening dick in my hand, how I was a real man now and stuff. I grabbed one of the socks I had just taken off and cleaned up the jizz, pulled my underwear and covers back up, turned around and tried to go to sleep. I remember my dick was feeling really sensitive under the covers, especcially the head.
All I could think of was that I wanted to do it again.
