When I was in school I wrote "Carmela's Property" on my toys to let everyone know that the best toys were mine and that no one would ever be able to use them without my permission. Today, you will be my little toy. I want you to write on your body that you are Mistress Carmela's property, so while you masturbate in front of the mirror, you will have in mind that your pleasure is controlled by me and that everything you do, you do it under my will and my permission.
