Mistress Emily was broke and she was not in the mood to play all nice to her pay slaves so as to get them to give her some money. She had dug up some secrets about a few of them that she knew they would not like exposed and she blackmailed them to pay her to keep quiet. She made more money that way than she makes when they give her willingly.
When this lovely lady has demands, she expects all of them to be completely fulfilled the matter what. Otherwise, a slave had better get ready for quite the humiliation, and even partake in getting kicked by one of her boots. She does not take any crap from a slave and expects nothing but the utmost respect can ever situation no matter how brutal or humiliating it can be from her.
