Princess Jessie doesn't keep lazy whores in her slave stable. If you are her property then you are expected to carry yourself like a slave at all times, including greeting her properly when she comes home and slavishly licking her shoes to show how grateful you are to be her pet. Lick the soles of her dirty shoes like you mean it, or risk being banned forever from her presence. A slave should be proud of his black tongue, it's a sign that he is properly licking her shoes clean.
