I am a writer little one, and I know from experience that the task at hand is far beyond reasonable, it is impossible. Even Stephen King himself at his wordiest could not accomplish this task. You need to take a look at how much you really want to be with a Dom who is going to be this unreasonable. A true and caring Dom/me cares about the welfare of their sub, something he clearly does not take into account. A D/s relationship is not only for the enjoyment of the Dom/me, but for the sub as well. Punishments are not supposed to be made so impossible that one is despondent and you are hitting that from the sound of your post. You really need to weigh the pros and cons of what is going on in your relationship.
I wish you the best no matter what your decision.
