This happened a few years ago.
A few years ago I knew a boy (we'll call him L) through my parents and his parents. L was a year younger than me, and I didn't know him very well. His parents were having a party, and I was the only kid there, other than him. So we went up to his room, and we talked for a while.
Out of the blue, he brought up the subject of masturbation. He told me his dad does it with him all the time, and he wondered if I had ever done it before. I hadn't ever,(I didn't even know what it was).
L pulled me into his walk in closet, and he pulled off his clothes. Just by looking at L, I could tell he hit puberty at an early age. It was something we had in common. He told me to take off my clothes, and without hesitation, I did. L reached over and started fonding my very limp penis. Once I was up, he gripped my penis, and started moving his hands up and down. The sensation was overwhelming! I sunk to the ground in pleasure. I came in about three minutes. I had never felt that kind of pleasure in my life!
L then put his three inch penis in my hand. He then told me to do the same thing to him. I copied him exactly, only it took him longer to cum, and when L came, his cum was much stronger.
I did this many more times with L, and we still do it to this day.
