Rule 1. The mirror will be kept spotless except for one intentional blemish. Every week when you clean it (and you will clean it weekly) you will leave a lipstick kiss print on it. Not in the middle where it could obstruct view but off to the side. Change the location weekly and ideally use a few different colors. It needs to be a bright, obvious kiss print. You may remove it should you have guests but the kiss print goes back up as soon as possible. You are not allowed to masturbate or even see porn without a kiss on your sissy mirror. Ideally you will have a cute pink cleaning rag dedicated to your sissy mirror. Cleaning is such an important sissy task, after all.
