I was at that age where I was hard all the time and didn't know what to do about it until I met Joey. His family lived next door to my grandparents and became a playmate of mine when I visited them.
One day we were in his room looking at comic books when he asked me if I ever 'jacked off'. That was the popular term for masturbation then. I told him I did not know what that meant. He said,' You know when you stroke your cock'. Again I said,' I don't know what you are talking about'. Annoyed he said 'your cock gets hard doesn't it'? My face got red and I replied, 'Yes'.
He got up and went to a table beside his bed and took out a small comic book. He brought it over to me and said 'take a look'. I opened the book and found pictures of comic book characters drawn naked with large cocks and breasts. They were in all kinds of positions and doing all kinds of things. I immediately started to get hard. This is what porn looked like back then.
Joey saw that I was hard and told me to drop my pants while he was dropping his. I didn't say a word but let my shorts drop.
A couple of years older than me, he had a very hard seven inch cock with plenty of pubic hair. I, on the other hand, had very little pubic hair and my cock was only about five inches but it was rock hard.
Joey told me to lie back on the bed and he would show me how to' jack off'. He took my cock in his hands and began to stroke it. It felt like nothing I had felt before. He kept stroking me and playing with my balls until I felt the most wonderful feeling I had ever felt. I shot what I found out later was called 'cum' all over his hand and my stomach. After a few seconds Joey said 'now that you know how to 'jack off' you can do me'.
I did and we did many times that summer when I first learned what pleasure was.
