Mistress Karina likes to do things her way. She, however, had a slave who liked to do things his way too. They clashed and she had to show him that it was her house and that he was her slave. She reminded him this by making him lick her smelly socks and her bare feet too. She kept the stinky socks to use in punishing people who pissed her off.
Mistress Nata was bored in the house but even in her boredom, she did not want to leave the house. That meant that whatever she did for fun had to be indoors. With nothing better to do, she chose to turn her slave into an object to have fun with. She turned him into a foot slave and got him to lick her dirty feet and smell her stinky socks. In addition, she used his mouth as a human ashtray. She did it slowly so as to pass time.
