Mistress Palina found out that her slave had been using her stuff without her permission. She did not like it as she felt he was crossing boundaries that did not need to be crossed. She remembered she had instructed him not to touch her stuff without express authority. He did and she had to punish him, which she did using her ball torture cbt fetish. The pain got to him and changed him.
This mistress was angry at her slave for not cleaning her sneakers well. She did not want him to do that again so she punished him. And she did it as cruelly as she could. She chose to make him lick them as well as kick him using them. He did not see that coming and he was shocked but he had no powers to stop her from punishing him.
