Hi trash boy,

Since you had been a devoted slave, I've got a special Christmas gift for you: my ex slave collar.

Do you know that, before becoming Miss Urbex, I used to be a slave?
So now you have the honour to wear this item and I recommend you to obey me, or you'll be punished with a whip.

Since I'd been a slave, I know your mind and weaknesses perfectly, so you can't lie and escape!
