Now, I may not be the brightest spoon in the drawer, and it seems I had to work this out step by step.
Picture the scene, I am 14 (at the time) and staying away from home with friends of my parents. For some time now, I have been conscious of my cock hardening and it feeling pretty damn good, but up until then, I hadn't touched myself.
Now, this particular night, I had been wrestling with my pathetic knowledge of 'girls bits' and thought the following.
'Hmm seems to me girls have this hole.'
'You stick your cock in there.'
(Grabbed hold of my erection at this point.)
'Then you move in and out.' (Moved hand back and forward to be greeted almost immediately with a desperate need to pee... or so I thought.
After a pause to let things calm down, I did it again. Yet again this tremendous feeling welled up...yet again, I let it subside. I had no idea that what I was really doing was building up something amazing.
Finally, third time around, I thought I would just carry on moving my hand up and down on my cock and see if I could 'work through' the feeling. I managed to hold on until the very moment, I thought it was subsiding, then I let go of my cock. The explosion was amazing, spurt after spurt after spurt. I knew something had come out of me, yet in a scene from 'Something about Mary' damned if I could find it. I looked on my PJ's, on the sheet, on the duvet (Inside AND out) Nothing. I even stripped the bed down and felt all over... STILL not a damn thing.
Scratching my head in puzzlement, I made the bed up again. THEN I saw the wall above the headboard.
If you have ever tried to clean a wall, in an old house with micro thin walls and the owners of the house on the other side you have NEVER lived. As I cleaned up my sperm, of course, the wallpaper which was every bit as old as the house started to yield up years of dirt, and by the end of the hour or so it took to make absolutely sure I had it all, there were eight bright, gleaming clean marks on an otherwise grubby wall.
Well, that was my first cum. Not the shining success of some on here, but interesting, nonetheless.
