Angry With Dad

Dad is divorces and after a while he started other women, it didn't bother until i knew he was sleeping with them i could hear them having sex in the next bedroom, they were not quiet about it, lots of four letter words, i was angry and very wet between my legs, i realised i wanted to be his girlfriend, at the same time i was disgusted with myself for wanting dad in a sexual way i wanted to take mums place in bed, i know its not normal, i told my best friend about it and she said i was a nut job,
