When my client ties me up I think many different things, like what I should eat later, should I buy those shoes tomorrow, what my mom is doing, if she's okay.

For the past couple of months I have a customer, who is disable. He likes to be tied up and hanged upside down. And he wants me to torture him really hard. He loves to pretend to be dead. It scares me. I don't know how hard I should kick him? Or how tight I should tie up. You know he is so fragile. I don't want to kill him. I don't want to get trouble.
