When I first discovered how to masturbate, I was thrilled. It was the most enjoyable thing of my life as a teen, and I still believe it is for me today. I think I was close to 13 or 14. When I was growing up, there were four of us. My mother, two sisters, and myself. Each child three years apart, me being the youngest. Since we were all girls, we really did not have a problem seeing each other naked, but we weren't really nudist. But we would do things like walk from the shower to our room naked, and sleep naked. We were clothed when we were around the house.
Although we were fine with each other nude, there was really no topic of masturbation. So I tried to keep it secret because I never knew my mothers opinion on it.
One day I think when I was 15, I was really horny for some reason. It was just me and my mom in the house, because my older sister was at college, and the middle one was on a date or something. So I was alone in my room, and I decided that I was going to masturbate. I laid on my bed, spread my legs, and began to rub my pussy. I was doing this for a while until I heard my mom knock on the door. I I got up and answered it and she said she wanted my dirty clothes. I gave her my hamper and she left. So I laid back on my bed and continued my business. I could tell that I was getting close to an orgasm when I heard the door open again. It was my mom returning the empty hamper. She saw me masturbating, and said sorry and walked away.
I was scared because I thought she was mad, and I did not know if I should approach her or not. But I didn't and I just went to sleep because I was mad.
The next morning I went down to breakfast and she told me that she was sorry about last night and she said that it was okay if I masturbate. She also added that she will knock every time. I was kind of happy that she was not mad, but still very embarrassed.
