Torture Me

A bdsm worker is met by a peculiar client who does not only want the activity but is specifically wanting the torture part.
It was just fun and games until he wanted to go further, asking her to use knives and blades, She tried to refuse but was threatened by him, if she won't do so, he will go insane and kill himself. That's when he revealed that he had a rare disorder.
So the girl gives mercy ironically by hurting him. Everyday is a new method, from fork in the hand, torches and peeling skin.
As she is tormented to her new daily routine hurting the man, She tries to find an alternative on how to fix his crazy mind.
But as the more she continued torturing him everyday, the more the man becomes calm and even caring as he is more and more being injured all over his body.
