Growing up, I lived in an all girl family. I had a brother named John, and a sister named Elizabeth. John was two years older than me, and Elizabeth was two years younger. My mother was a nurse, and she was always gone long hours. I have been masturbating ever since I was 10 years old, and I knew that my younger sister masturbated when she was about 13 because I shared a room with her.
But anyway, there was one day during summer break that my mother was gone the whole day with my younger sister, and I was supposed to be at my grandmothers. I was 14 at the time and my brother was 16. But in the morning, my grandmother called and told me that I could not come over because she was sick and she did not want me to catch anything. So I stayed home for the day, but my brother was unaware. I went back to sleep and woke up to the sound of the shower running, so I knew that my brother was in the shower.
I went downstairs to get some breakfast, and then I came right back up. As I was coming around the corner in the hallway, I saw my brother naked coming from the shower. She jumped and tried to cover himself, but I had already seen everything.
