Lady Krasaviza wanted her slave to clean her sneakers. She had expected to find them clean and now that they were not, she had to both punish him as well as force him to lick the soles of her high heels. That way, she would have the sneakers clean and she would also humiliate and punish him. He was also ordered to smell her sneakers besides licking the soles of the sneakers.
Mistress Catherine knew how clean her slave was and she wanted to use that fact to humiliate him and to make him pissed. She used her dirty sneakers to step on the white carpet and knew that she would make it dirty. The mistress then let him see what he had done and she laughed and was happy at how he was angered. But he could do nothing about it however angry he was.
Princess Kitty had gone for a long walk. She was exercising as well as clearing her mind. And since she had a lot of time on her hands, she went for a long walk. And when she came back, her feet were sweaty and her shoes were stinky. And in that state, she used them to humiliate and to degrade her slave for not following the instructions she had given him earlier.
Mistress Cassandra knew this guy had never been dominated with sneakers before and she was ready to give him a taste of it. The naughty mistress laughed at the guy as he made faces while licking the soles of her sneakers. She knew the punishment was effective and she had a great time administering it. Mistress Cassandra then let him go having accomplished what she had set out to achieve.
