Open Question: My little sister is blackmailing me with my foot fetish?

[feedcrawler]

My sister has known I have a foot fetish for a while now. When I was like 9-10 years old and I didnt know it was a sexual thing at all, I would rub my sisters feet, nothing more just rub them. Eventually i decided I could trust her and told her the situation after I figured out I had one. Instead, she threatens to tell my parents, post it on Facebook, put it on YouTube , and tell my friends, if I dont let her play my PS3, or give her money, or do her chores and i'm sick of it! Please someone give me some advice on what to do! I only rubbed her feet when I was 9 years old, Im 13 now and dont do that stuff.
