First time story

It happened the summer after I turned 13.  I had been getting more and more curious about girls, and girls bodies, and noticing girls in bathing suits with nice boobs and such.  My cock had grown, and I was getting hard ons pretty regularly but I just didn't know what to do about that!  I had heard boys at school joking about this thing they called beating off or jerking off and I knew it had something to do with rubbing your cock but at that point I didn't know what the result of that activity was.  I had seen a few porn magazines by that time but didn't yet realize the main reason guys looked at them was for masturbation.

 This all changed when I discovered my older brother's sizeable porn magazine stash in his closet.  He must have had 40 or 50 magazines.  Being curious, one evening when my parents were picking up my brother from an activity a couple towns away, I knew I'd have the house to myself for at least an hour, so I snuck a few porn magazines into my room.  I propped myself up on the bed and began to flip through them.  The pictures were amazing and I quickly got very excited and grew an enormous hard on. When I slipped my shorts off and started experimenting with ways to touch my cock I gasped it felt so good.

I was determined to do this beating off thing and trying it while looking at the magazines made it all the more exciting.  I took the rest of my clothes off and as I looked at the magazines, the movements of my hand along the shaft of my cock became more urgent.  My heart raced.  I didn't realize what was happening but I knew I didn't want to stop.  Then this overwhelming sensation of pleasure hit me, and my body convulsed in its first orgasm, and although I was nearly passing out from the intensity of it, I felt the warm jets of cum spraying all over my chest and stomach.  I had clenched my eyes shut in that moment of extreme pleasure and I opened them to see my hand pumping the last spasms of cum from the tip of my cock.  Between the intensity of the ogasm and the amount of cum I had released, I was pretty much in shock.  Several of the magazines had fallen on the floor due to all my writhing around on the bed.  I had at least 10 sizeable gobs of cum to deal with and nothing to clean it up with other than an old t shirt.

I instantly realized that I had discovered how to jerk off and that jerking off led to this incredible feeling and that I had to be better prepared to deal with all the semen.  Just to make sure what I had experienced was real, a short while later, I masturbated again, with equally spectacular results.  Needless to say, that old t shirt was caked with cum within a couple days of my discovery.  I quickly became very adept at beating myself off and pursued  solo sex with a fever-like passion all through my teen years and beyond.  But I'll always remember that first time, on a warm summer evening at home alone and the wonder of that discovery at the age of 13.
