Mistress Zephy did not like bullies. She had been bullied before and she knew how it felt. So she took it upon herself to put an end to bullying wherever she could and when she found out that this guy was a bully, she had to torture him and dominate him. She did not care what he felt. All she was doing was giving him a taste of his own medicine.
Mistress Zephy wanted to try things she had never tried before and that is why she chose to use her trampling to torture and degrade this loser. The mistress went out of her way to make this guy cry and beg her for mercy as she used her high heels to trample him. And the mistress loved the punishment as she knew that it worked well and she could use it anytime.
Mistress Zephy wanted to dominate this guy and she did it after she had flirted with him. She was trying to make him not realize that she was making fun of him and she was taking advantage of him. As he enjoyed how she flirted with him, she was making him lick as well as smell her feet and sitting on his dick. But he could not say anything about it.
