My first time masterbating with another boy was when I was thirteen. My friend Jay and I had built a fort in the woods, we were both hot and sweaty. Jay said we should take our clothes off and cool off. Slowly we both undressed and stood clad only in our undies. We looked at each others crotches before we slid our undies down our legs and off. Now we stood naked before each other, sure we had seen each other naked before but this time it felt different.
We then sat down on a log nearby and let the cool breeze cool us off. As we sat there I tried not to look at Jay's crotch, then at one glance I noticed that Jays penis was erect and he was playing with it. I looked at my penis it was erect too. I reached down and took my penis in my hand and slowly started to slide my hand up and down the smooth shaft just like Jay was doing.
Faster and faster we went until we shot our loads of semen all over the ground between our spread legs. After we had finished coming we both commented on how great that felt, it was the beginning of the many times we masterbated back at our fort.
