My sister

My sister by
When I was thirteen years old and my sister was 11, we hadn't seen each other naked for many years. One day I came home earlier than expected from school and I found my sister completely naked humping the arm of the couch. She had only really small breasts, mostly nipples, and she was almost hairless. Plus she was really skinny. She was a bit startled and stopped, but I couldn't get her to start again.

I would always try to catch her after that, but was never able to. I did sometimes catch her playing with herself alone in her room, but when she saw me, she would instantly stop. I tried to talk to her about it but she didn't want to say anything. Once she admitted to me that she plays with herself and tells me about her friends masturbating, but I have never seen her masturbate again.
