I grew up in a small farming community and experienced the following. One afternoon, I was at a friend's house and we were sitting around outside. I was 11 and he was 12 years old. All of a sudden, he asked me 'do you ever jack off?' I said 'yes' and he said 'well, maybe we can do it together sometime.' I said that would be OK with me.
Nothing more was said until a couple of weeks later and we were riding our bicycles. He said let's go somewhere and jack off. I said OK, 'where?' He said let's go to the woods which were behind his house. So, we went there, lay on the ground, pulled down our pants and underwear, and took out our dicks and began playing. I think mine was about 5 inches by that time, and his was a bit longer than mine, and curved upward. We were both uncircumcised. I could climax, but was a bit too young to produce semen. My friend could, and before long we had both reached climax, and he shot some semen onto his belly. He was only the second person I had seen shoot some cum (the other was another friend). We said we'll have to do it again sometime.
A few months afterwards, my friend asked me to spend the night with him and I did. By now, I was 12 years old, my dick was a bit longer, and I jacked off 2-4 times every day. I knew that it wouldn't be long before I too could produce some semen, and was eager for that happy day to arrive. When we went to bed together, we made small talk about school and friends and of course, girls. He wanted to know if my dick was hard, I said yes so he asked if he could feel it. I said sure go ahead, so he took it in his hand and I did the same for him. We stroked each other a few times and then he asked if I had ever taken a dick in the butt, and could he do that to me. I said I had never done that and 'you're too big' and nothing more was said about that.
We continued jacking each other off, and it felt great with his hand on my dick. All of a sudden, he spurted some cum out onto my hand and I felt my climax about to arrive. I thought it would be the usual 'dry' climax, but this time it was different. I felt the warm ooze of my first semen begin to come out, and my friend felt it also. I said 'I think I just had some cum!' My friend said 'let's see' so he got up and turned on the light, and sure enough, there was the wet stuff I had waited so long to produce. It felt so good, and I was so proud of myself.
That was the last time my friend and I ever jacked off together, but I continued to do it 2-4 times a day. I fantasized many times about that mutual session. I had several jack off experiences with other friends after this one, and will write about some of those in the future.
