First, a little backstory. When I was 11, bordering on 12, I was cut. Now, once I recovered it seem puberty hit me like a ton of bricks. I was hit by erections hourly it seemed.
Now I learned to masterbate in a very weird way. It was about 6 months after the op. My friend was over, and for a laugh I typed in 'Nudists' into an image search. We got some really hot pics. I dont know about my friend but I was rock hard.
Some pics where blurry, so I leaned in to get a closer look, as I did, my dick rubbed aganst my trousers, and leather chair. Damn it was good! I slowly slid up and down the chair, my mate didn't notice, and after about 20 minutes a sudden urge to pee hit me. So off I went, yet nothing came out.
It was then I realised I had just jerked myself. I was surprised as I had been told cut kids can't jack. When I tried to do the normal yank it method, nothing happened. Not a single good feeling. Then, I tried to remake the 'rubbing' sensation. I got hard, and pushed my dick agasnt me, and used my hands to rub the bottom of the shaft. Took a bit, but BOOM! Orgasm. I just lay there feeling very relaxed. I noticed that the pressure from my hands prevented any cum comming out.
This combination meant I could jack to porn on the computer without putting my hand down my pants, or taking them off, I could do it through the clothes. This meant when a heard a knock, I could close the window and just look as if nothing happened. It also allowed for jacking at sleepovers, with my friend none the wiser. However as I've aged a bit and I make more cum, when my hands loosen slightly, some does come out. And, if I came really hard, it all seepped through my trousers.
This brings me to my story. My friend was sleeping over, he was a deep sleeper and slept way late. So I thought, better pass the time. Seeing as he was in a sleeping bag, If I put the covers over them he couldn't see jack, even if he did wake up. So, feeling a little extra horny, I stripped down, lay under the covers and jacked my brains out. In a few minutes I hit orgasm and came. As I lie there, I feel this warm spot. Dreading the worst, I look down and small collection of semen is on my stomach.
I looked around for anything to wipe it up, but if I moved the cum would drip everywhere, and my friend might wake up and seem nude with cum on my gut. So, preparing for the feeling, I put my shorts back on and let it absorb it all. So then I had to lie there for another hour in cum encrusted pajama shorts...
Luckily, he was none the wiser!
