Goddess Gabriella wanted to use this guy as her human foot rug. He had been pissing her off and she wanted the perfect way to demonstrate to him that she was not happy with him. She felt that using him as her foot rug was the best way to do it. So she did it and she made him feel pain and humiliation in equal measure. He never messed with her again.
Goddess Gabriella and her friends Cleo and Scarlet wanted this guy punished for stealing their secrets. They did not want to wait for someone else to go and do it for them. That is why they chose to do it themselves with their high heels. The mistresses used the heels to send a strong warning and message to him which he understood immediately because of the pain that he felt.
