This is not about sentence structure but a grammar question none the less.

When is master,mistress capitalized?
I've heard that it should be capital M when refering to a specific individual, such as "Please Master, not in the face."
But when talking about the position or relationship it should be a small m.
The mistresses gathered around the coral. It was always fun to watch a master break the ponies.
Is this the rule? It certainly makes a writers life a little harder. Maybe I should have taken up historic romance novels.
