Filthy Taboo - Casca Akashova

I have been having a hard time in school, in better terms, I was failing. I knew I could never let my Dad know I would never hear the end of it from him and his wife. I was trying to be on my best behavior but my Stepmom Casca realized and knew I was up to something. I had to admit to her that I was failing, she lost it on me and kept yelling at me. I need her to promise not to tell my father, she agrees but only if I do one thing for her... fuck her...
