I molested my best friend's little sister when she was 5, I was about 13. I'm 34 now, she's 26 and we've been together for about a year.

Sometimes I touch her in the same way I did when she was 5 and she gets super horny but she doesn't understand why. I guess she has just forgotten that I molested her.

For example, one time when she was 5 we were in my best friend's living room. We were watching TV and my friend got a call from their parents that he needed to run to the store and buy something. So he left me alone with her little sister. We were watching TV, I was sitting in the sofa and she was standing in front of it. She was wearing a skirt and I couldn't help myself. I lifted it up, pulled her panties to the sides and fingered her asshole while I touched myself. I think she was more surprised than anything, she squired a bit but I told her to stay still. Which she did. I fingered her ass until I came. I did this every time I got the chance and she started to like it.

Fast forward 20 years and we were off to a family gathering. She was wearing a skirt and I couldn't help myself. I sat down and told her to come over and turn around. Which she did. I lifted up her skir, pulled her panties to the side and started fingering her asshole. She really liked it but she almost came when I told her to stand still.

I've tried a couple of other things I did to her as a child and the result is still the same, she cums almost instantly. Moral of the story, always molest your friend's little sisters.
