Empress Kira wanted answers which this guy had but he had refused to give them to her. She was not going to beg the answers from him and that is why she took the step to punish him and make sure that the pain made him talk. She cruelly forced the guy to talk using her foot domination. He did and regretted why he had refused to give her the info.
When mistress Dorimills and mistress Jucy realized that they were dealing with an insincere girl, they had to teach her not to be insincere again. They took her to the woods and had a great time torturing her for their own fun and to make her see some sense and change for the better. She was made to kneel down and had to lick their sneakers which were dirty and muddy.
Mistress Kira and mistress Sofi found this guy staring at them and they knew he was interested in them. So they told him that they had a fetish for feet and easily got turned on when their feet got licked and the guy was interested although he did not say a thing. They sweetened the deal by offering to pay him and he licked their feet despite the fact that they had spat on them.
Mistress Kira wanted this guy to learn his lesson the hard way and that is why she chose to do some crazy things to him. She wanted him never to forget that she can be cruel when she means to and so she used her sneakers to crush his head and pump some sense into his brain. He was in pain but he tried his best not to cry as she was afraid of pissing her off further.
Princess Kira and mistress Sofi did not like how their slave behaved. They wanted him to change so that he became what they wanted him to become and to behave how they expected him to behave. So they used foot domination to show him that if he did not change, he would have it rough and he would have to endure a lot of pain as well as humiliation. He chose to behave like it was expected of him.
