Lady Scarlet did not like how much of a snob this guy was. She did not like it and she had to make sure that the guy learned his lesson and that he changed his ways. So the mistress used her boots to show the guy that she did not like what he did as well as how he did it. And the pain got to him and he changed.
Lady Scarlet does not tolerate lateness from her slaves. And when this slave was late without any apology or without proper cause, she had to punish him and she was swift in doing it. The mistress stripped the guy naked and then went ahead to force him to endure being caned as well as being used as a human pony. He had no choice but to learn the hard way never to be late.
Lady Scarlet wanted to test how much pain her slave was able to endure and so she used her cane to do it. The mistress stripped the slave naked and she caned him all over his body with concentration on his ass. He was in pain and he cried as well as peed as she caned him. She knew he had very low pain tolerance and she stopped as she had gotten her answer.
