Goddess Lena had a new slave and she did not wait for him to mess up for her to punish him. She just did it so that she would send a message to him about the kind of person she was and why he needed to be careful about what he did so as not to piss her off since there was no telling what she could do to him.
Goddess Lena did not like how rude her slave was and she had to put an end to that shit that very day. So she used her riding boots to teach him a lesson that she hoped would serve him for a long time to come. The mistress dominated him and made sure that he learned his lesson the hard way. The mistress not only trampled him, but she also made him lick her dirty soles.
