You will do exactly as I say. Listen to me like your life depends on it. I want you on your knees on the floor begging and pleading with me to take you money. I know you're hard just thinking about the possibility. The only chance you have of cumming is me maxing out all of your credit cards and taking ever cent out of your wallet. So let's begin.
When they get up, they know they will make money. Their slaves know that if they want to get any time alone with their mistresses, they will have to pay for it. If they don't have any money, they are not allowed to come near their mistress and they won't be able to speak until they get the money. When they are able to pay, they are allowed time that corresponds with their money. The more money they have, the more time they get with their mistress.
When Nikki decides to take over a slave financially, she has a soft and sweet way to do it. She hypnotizes them. They are stopped by her beauty and loves to listen to her soothing voice. AS they go under hypnosis, she tells her new slaves they have to pay to be with her. She enjoys having her slaves pay for her lifestyle. She can't find other uses for her slaves.
