A Dominant woman taught me this rule. This rule applies to all of us, single or taken. Vanilla, submissive, or slave - all. I liked it.
Rule #1: Always take care of Master’s property.
You have a responsibility to take care of yourself. Mentally, physically, emotionally, in every way. You must always take very good care of yourself, and your body, for the person who is meant to love you.
Basic needs like eating well, getting enough sleep (kitten is currently failing at this), being productive, and working hard. Taking care of your body, as it does not belong to you. In all things you should give thought to what they would want for you, and be proud of yourself.
Even if you are single.
Negative thoughts, self-harm, unhealthy habits - things your Master would not want for you, work on them.
Toxic or abusive relationships are part of this rule. Your Daddy or Dominant would not want you to suffer without consent, or in a relationship that is bad for you, even with another Master. No one has a right to abuse what is ultimately theirs. Including you. Be brave and recognize when you are being abused.
Sometimes walking away is taking care of Master’s property too.
Even if you haven’t met them yet.
