Mistress Gaia loves her high heels because they are more than just a fashion accessory. She likes the heels because she can use them as a weapon to defend herself or one to punish someone with. Today she used the heels as a tool for punishment. She made this loser lick her high heels and threatened to crush him and trample him with the same heels if he did not lick them well.
Goddess Nika is not your average mistress. She is hot and she loves naughty things. But what differentiates her from most is the fact that she loves and she enjoys it when she inflicts pain on other people. She is a sadist and loves using her high heels to crush people's head and their balls. She does not care about the kind of pain she inflicts as long as she has fun.
This mistress was not happy with the state of affairs in her house. She had to make things change and she did it by humiliating her slave. She forced him to do what she wanted and he did it against his wish. She had had enough and so she forced her slave to lick her feet which were sweaty and smelly and she also had him do the same to her heels.
