I had been jacking off regularly 3 or 4 times a week since I learned how good it felt. I was very curious to know if other boys my age (age 13) were also jacking off. I knew it was something that you just did not want to ask other guys. My best friend Nate was is my grade in school and we did all the boyhood things together like playing sports and riding dirt bikes.
One rainy Saturday Nate and I were in his bedroom playing cards. Being curious if Nate had discovered the joys of masturbation I suggested that we play strip poker. Nate to my surprise agreed without hesitation and my cock immediately began to get hard. Nate and I soon were both down to only our underwear, both of us were sitting trying to hide our boners that were trying to escape the confines of our underwear. Nate lost the next hand and had to remove his underwear. I was so excited about seeing his cock that my cock was beginning to spasm on its own. Nate turned his back to me and lowered his underwear and slowly turned back to face me. Nate had the most beautiful shaped boner. It bent slightly and sloped perfectly towards the sky. My boner mostly stuck straight out in front of me. Like me Nate was hairless and about the same length.
As Nate sat down to continue our game I asked him if he jacked off. Nate said that he had been jacking off regularly for about six months, but had only been 'shooting his load' the last couple of months. He said that prior to that it felt really good, but nothing compared to when he started cumming. Nate told me he learned about jacking off when he saw his 18 year old brother standing in front of the bathroom mirror and sink with his hand moving up and down on his cock. Nate said then his bother started moaning and he groaned loudly as he shot his load into the sink. Our game continued and I lost the next hand and stood to remove my underwear. My hard on was ready to be released and not only from my underwear. Now that both of us were without clothes we looked at each other and began to jack off. It was not long before I was ready to cum so I grabbed my underwear and proceeded to cum into my underwear. I left the head of my cock exposed as I was cumming so Nate could watch. This pushed Nate over the edge as he grabbed his underwear and gave me a show as his cock exploded with stream after stream of cum into his underwear.
