Goddess Lena wanted this slave to feel the pain of her boots on his body. She knew how painful it was but he did not because it had never happened to him. The mistress knew that for it to be worthwhile, she had to make sure he was naked. So she stripped him naked and she cruelly trampled him. It was brutal but it served its purpose like it was intended.
Mistress Kira wanted this loser to stop taking her for granted. So she plotted a befitting punishment which she then meted out on him. He was taken out in the snow while only wearing his boxers. Then he was made to lick her snowy boots before she used the same boots to crush and stomp on his bare back. He was in pain and it was extremely cold. He learned his mistake.
