Rough femdom has an even tougher time than rough maledom. Any story with only unremitting negativity towards the sub/slave chills reader reception. You include several 'only mistress being happy matters' statements, but they come across as bad melodrama. You make him come from all the mistreatment; a few will like that. Many find it causes a variety of non erotic emotions.
You need to give her at least some basic concern for his welfare or do better at selling the idea this is a positive experience for him. It is about more than orgasms.
I was not impressed as all that mattered was the Mistress and her friend's happiness. The slave/dog was not given any positive feedback and he was humiliated just to entertain his Mistresses friends. A sub/slave relationship is not all one sided.
