This mistress took a giant doll and crushed it till it became a tiny one. She had used her ass to do all that. But she was not done. She continued with her humiliation and by the time she was done with it, the doll could hardly be seen. It was so tiny. She was practicing for when she was going to crush and shrink her slaves and humiliate them.
This mistress loves to humiliate. And she does it for financial gain. She knows that her slaves are loaded. So instead of asking them for money, she just makes the pay pigs to be tiny men. She uses her vore fetish to transform them and then pretends to leave them in that state. The little men are always afraid and humiliated. They suggest that they will pay her to transform them back and she agrees.
