I had my first orgasm when I was 12. I did not know anything of this before. Sometimes I rubbed my dick and he became hard but nothing happened then.
I think I needed at that time an example.
One day I was alone at home and very bored. I looked out of the window but there was nothing exciting happening outside. So I looked into the windows of the other people across the street and I saw this nice young man. He was new to the neighborhood and I did not know him. I think he was in his early twenties. He looked very good and somehow I became a bit horny.
He lay on his bed and he began stroking his chest. After a little while he took off his T-Shirt and I could see his nice chest. He glided across his chest and his stomach into his jeans. I could see that he softly rubbed his dick and he was enjoying it and he began to smile. I became hornier and hornier and I felt my cock swell in my jeans.
Softly I began to stroke him through my jeans. During that time the young man opened his belt and then his jeans. He wore white boxers and I could see a big bulge in his boxers. By now I was so horny I took off my trousers and my briefs (I also had a bulge) and rubbed my dick with more intensity. The man stroked his dick through his boxers and became faster and faster. Then he took his boxers off and I could see his big cock. Wow, this was so hot! He began to massage his balls, and I could see that he was moaning. He enjoyed himself so much.
But suddenly he stroked so fast till he came. He shot his cum on his chest and his face and looked very exhausted but also very, very satisfied. Then he began to take his cum into his mouth and I think it tasted good to him. But for me this was too much I shot my load in four ropes out onto my briefs and my jeans. It was the greatest feeling I ever had and I knew from that point on that I was no longer a boy but now a man.
