When I was nine years old, I used to play around with my brother's penis. He was 12 and I caught him jerking off in the bathroom. He tried to hide what he was doing but I called him out by threatening to tell on him. He confessed that he was jerking off. I asked him why and he said he needed to. Curious, I asked if I could touch it. He said OK but only if I could keep it a secret. He showed me how to stroke it and rubbed my pussy with his fingers. It made me wet and then before I knew it he was on top of me. He started fucking me with his huge cock. I found out later it was 10" long. It felt like it was splitting me apart. He pulled it out and shot streams of white hot gooey liquid all over my stomach and chest. I found out what it was later on. He asked me if I liked it and I said yes.
