Mistress Megan had not humiliated anyone in a while and she missed it. She set up this guy so that he would do something cruel and then she humiliated him. She used her high heels to do it. He was ordered to lick her bare feet and when he was done, he embarked on her high heels. She warned him to do it well or else he would be crushed and trampled using the heels.
This mistress was tired of how nagging her boss was. She could tell she had power over him and she chose to use it for the first time. The meeting was heading nowhere as he was not coherent. She chose to have fun at his expense so she made him lick her shoes as well as her bare feet and she was surprised with how quickly and how nicely he did it.
