This story takes place when I had just barely turned 13. I have two brothers and one sister. Each of my brothers get there own room and I have to share one with my sister. I was 13, I had about 32b boobs, blonde hair, a nice figure, and a nice little bush of pubic hair. My sister was 16 at the time she had blonde hair, a nice figure and her boobs were bigger than mine obviously. Our room was kind of big and it had two level beds. One for me and one for my sister. At night I would realize my sister was panting and breathing hard under the covers. During the day I would look at the sheets and see that there were some stains that you could see if you looked close enough. I didn't know what she was doing or what the stains were. This continued for about a month. She would do it every single night. I told my mom that she was doing weird things at night and that there was stains on her sheets and she said 'Sometimes a girl needs to relieve herself.' I asked her what that meant and she said that I should ask my sister. My mom did not tell me anything about it so I still did not know what she was doing and I did not want to ask my sister.
It took me about a week to build up enough courage to ask my sister what she was doing. One night while she was breathing hard and panting (the usual) I asked her what she was doing. She at first said nothing, but I really wanted to know so I asked again and then she said that she would show me. She took the sheets off of her and she had her pj t-shirt pulled up over her breasts and her bottoms pulled down to her knees. She said 'take your clothes off.' I was a bit hesitant but I did. She turned a small lamp on in the room so now we could see a little better.
Then she sat down naked on her bed and I sat naked next to her. She opened her legs and showed me her nice pussy. She was fully developed, and I was still growing. She said to follow what she was doing. She placed two of her fingers inside of her vagina and started to move them in and out. I still did not know what this did, but I did as she did. I began to move my fingers in and out of my pussy. I was getting wetter and wetter and I said to her that I was scared. So then she just starts to finger me. She said it was supposed to feel good and that I was supposed to get wet. She repeated the process on me for about five minutes until I said I was about to pee. She said that that was normal and I was not going to pee. All of the sudden I felt this wave of pleasure come over my body and I started breathing hard and squirming. My sister said 'That was an orgasm. That's what happens when you finish.'
I was so happy to learn what masturbation was. I did it practically everyday since that day. I even showed one of my brothers how to do it.
