She one told me she always crazy about sex, even from a early age. That was the reason for me have born when she was only 15yo. With time her sexual desire didn't change. I was raised by my grand-parents until I was 20, then I started to work and went to live with my mother and during the first year I was there, I got used to see her getting fucked every night by a different guy she brought home. Until one night she came home alone, she came in to my bedroom and said: "I was thinking about this for a long time and tonight is the night". This was 4 years ago, we still fuck like rabbits almost every night and she stop bringing guys home.
