Goddess Lena was out to humiliate this guy and she did it in a cruel manner. The mistress forced the guy to lick her smelly feet while she smoked. But when he was done, he was also turned into a human ashtray and he had to feel the cruelty and pain of the mistress' cigarette. In addition, the mistress blew smoke on his face and he nearly choked on it.
Goddess Lena does not like to postpone punishments because she believes that whoever is in need of the punishment might forget why he or she is being punished and do that mistake again. So she used her shoes to dominate her slave and she made sure they were smelly. Then he had to sniff them and also lick them according to her instructions. He did it to avoid further punishment.
