Princess Serena was not happy about what her slave was doing. She had to get him to change before he got used to the bad habit. She used her smelly feet and her stinky socks to make him change. She choked him using the feet and the socks and by the time she was through with him, she was sure he had changed. And true to what she thought, he changed.
Princess Serena caught her slave doing what she had told him not to do. She was surprised at how disobedient he was and she had to punish him there and then. She did this by trampling him with her high heels. She forced him to lick her bare feet which were dirty and she made him do all the nasty things she wanted him to do. She knew he had learned his lesson.
