He taught me.
I was fourteen or fifteen at the time, I had a dog and I always took him down to the park for a run. Over the months I became friends with a guy, he was about 35, he also had a dog and he was a nice guy to talk to.
One day I just went down the park to see him, it was a little bit cold and he had a coat on. When I sat next to him on the bench we talked for a little while and he then opened up his coat and I saw he was masterbating himself. I was fascinated looking at this massive erection and him slowly moving his hand up and down. I couldn't talk I was speechless. He asked me if I masterbated, I said, no I didn't, and he asked me if I would like him to show me how, as if I needed any teaching.
I said ok. He asked me to grab his dick and just do what he had been doing. I did this, I remember how big it was and how great it felt in my small hand, it was massive. Thinking back it seemed to be about ten inches long. I stroked it and pulled it harder and harder until he told me to stop. He said it was my turn. We then went into an alcove at the school nearby, he took my pants off and out popped my five inch little thing ready for what ever he was going to do to me.
He played with my penis for what seemed for ever, being very careful not to make me come, it was heaven. During this time he stripped me off naked and he took off all his clothes and we laid on his coat in a 69 position, he then started to really work on my dick and my arse hole with his fingers. I can still remember the feeling, lying there completely naked, 14 years old being pulled off by a guy old enough to be my father. His dick was massive as he brought me to orgasm, he timed it beautifully, he sat up and came all over me I was drenched. He then used his sperm to lubricate my dick and arsehole and the feeling was fantastic. He pumped my dick and my arsehole with his fingers very fast and hard, the feeling was unbelievable. I came on him as he was lying naked beneath me and I was standing above his face. He loved the taste of my come. I saw him many nights after that but that, as they say, is another story.
