Goddess Ellyah needed to teach this guy a lesson that no one had ever taught him. That is why she did what she had to do and by the time she was done with the guy, he had learned his lesson and he had done things the best way he knew how. He licked her smelly socks and he had to suck her toes and do other degrading things as well.
When mistress Andreea and mistress Samariel realized that they were dealing with a loser who did not want to do things the right way, they had to punish him and they did it with their foot worship fetish. He was cruelly turned into a foot slave and he had to lick their feet and do other humiliating things. He tried to beg for mercy but the mistresses did not let him off the hook.
