Biggest Secret Blackmail Fantasy

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 havent told ANYONE. The one youve been harbouring for years.. decades even. The one that could strip your entire life away in an instant if it got out.Thats the one I want, and YOU are going to give it to Me. I always get what I want!
