Alright, so my lil sis sometimes locks her bedroom door. I asked her why and she says "for privacy" but I didn't know what she was exactly doing in there. It would last about 10 minutes and then she would come out. Sometimes I would hear the bed move and her breathing really heavily. One time I heard her fall of the bed. Keep in mind that she's 12. There were times when I heard her moan. Yesterday she forgot to lock the door. I came in and she was lying down on her bed in this weird position. Her hands were tied together and she was rolling her eyes for dramatic effect. Her legs were in this x position. I'm assuming that she was fucking herself. When she saw me she fell off and pretended that it was nothing. She was like "I told you to not interrupt my session. I was too afraid to ask her but I just accidentally found out her secret. Now I can't look at her in the same way again.
