Mistress Zephy had a landlord who wanted to have a relationship with her in exchange for not paying rent. She felt insulted by that and she had to put him in his place which she did with her high heel boots. The mistress made him lick the soles of her boots and she kicked him in the nuts before she chased him from her house as it was still hers until she stopped living there and as long as she paid rent.
Mistress Zephy wanted to try high heels femdom as she had never tried it before and her friends had told her that it was a lot of fun. So the mistress did what she does best and she tried it. But she waited until she had a loser to try it on. The mistress enjoyed how she was able to have fun and humiliate the slave at the same time.
Mistress Zephy wanted her slave to learn never to piss her off and she had to scare him to get that kind of reaction from him. So the mistress went out of her way to use her high heels to do the scaring. He was so pissed and he was so scared that by the time she was done with him, he feared her more than she expected he would.
