I guess I was about 12 and I hadn't really developed. In fact I don't think I had any dark pubes at all, but my cock was getting more mature.
I had a friend whose name was John, and he had a friend whose name was Carl. Carl was a bit older and had a car. One day John and Carl came over to the house and said, "Let's go for a ride." I climbed in the back seat and we drove around a bit. Then John asked me if I ever saw some anyone cum. Being naive, I told him I hadn't, but would like to see it happen.
We went on the dirt road in the backcountry and parked the car. Carl, who was older and more mature, unzipped his fly, before pulling out his cock. It was much bigger than mine! Thicker, longer and had lots of curly pubic hair. His balls were big and hung down in their sac. Next, John unzipped his fly and pulled out his cock. It was smaller in size, not being as thick, but his balls were big. I then took out mine, which was much smaller. I had just started to get some very light pubes, but my cock hadn't really started to mature. My balls were also not as large as the others. We all commented on their differences.
John then started to play with Carl's cock and it got hard in an instant. The head was swollen and pre-cum was oozing from the tip in anticipation. John started to stroke it, grabbing at the very base and pulling the skin up to the ridge. At this point I reached over and started to play with John's hard cock. It too was oozing pre-cum.
John was stroking Carl and playing with his balls. Faster and faster, John stroked until Carl said he had 'the feeling' so not to stop! Meanwhile, I stopped playing with John and just watched in awe. All of a sudden Carl said he was going to cum. Boy did the jism fly out of his cock and all over the place! It was an awesome sight and I couldn't wait until I was able to cum like that. It was then John's turn and he was able to cum too, with our help.
The three of us would go for a ride often. We always ended up jerking off each other. It was a fun innocent time in my life.
