Im a 14 year ild girl living with a divorced mother. My dad just up and left us one day. About two months ago my mom came home from work about a hour early. She walked in to find me in middle of the living room stark naked except a pair of pantyhise with the crotch ripped out, on my hands and knees with our German shepherd dog on my back knotted inside me. She wasnt mad or even upset. Shicked at first we both wete but she sat on the couch right beside me and spoke very calmly abiut my activities. During this I told her ive been foing it a while and that I just decided to try it one day and liked it. She told me that I looked very beautiful and seemed natural. She also stated that it didnt look sick or perverted but very erotic to see me like this. By then the dog had pulled out of me and she gasp at his size. After some more talking, she told me she never wants me to hide this again and to do it openly whenever I wanted to. She loves the dirty stuff I say and says stuff herself as she watches and masturbates. Her and I have started to fool around more and more. It started with some open mouth kissing while I was getting it from the dog but has quickly turned to full blown sex.
