Sitting on Useless Skinny Sub

Description: I am exhausted and my room is a mess. i call in my skinny submissive, frank, and demand he gets to work picking up. i quickly realize how helpless he is at cleaning - and cooking - and massaging - and even just being a foot stool. what am i to do with such a useless skinny man? i humiliate and degrade him every step of the way before finally laying him down to just simply be my chair. can he even do that right? maybe i just need to keep sitting on him until he learns. lots of verbal humiliation.
