Biggest Secret Blackmail Fantasy Task

Description: Handing over identifying information is one thing... but handing over something so personal and so secretive is a whole other ball game. i want the secret that you haven't told anyone. the one you've been harbouring for years.. decades even. the one that could strip your entire life away in an instant if it got out. that's the one i want, and you are going to give it to me. i always get what i want!
