I expect my slaves to address me formally. It shows respect and underlines the power dynamic. PMST has been a permanent part of my slave stable for several years now. He very rarely fails to use the correct form of address when speaking to me. Today, however, it happened to him. Twice, right in a row. My slaves have to stay in character at all times. Misconduct is always punished, and in this case, that means 10 strokes with the cane - cold caning!
