Sister taught me to masterbate
My older sister taught me how to masterbate. When I was about 8 or 9 years old, she was always grabbing my little pecker and playing with it. One night, she came into my bedroom and woke me up. She climbed into bed with me and grabbed my little cock and started stroking it. It got big and hard and it felt really good. I noticed she was rubbing herself between her legs while she stroked my cock, and I asked her what she was doing. She said it's called masterbation, and that boys and girls can both do it, but brothers and sisters shouldn't do it together so I had to promise not to tell anyone. We played with ourselves and each other nearly every might after that first time. We had some great orgasms together, and progressed to giving each other oral sex, but she never would let me put it in her vagina.
