Goddess Kiffa was trying to explain certain things to this guy but he was slow and he did not grab the concepts. The mistress did not like that very much. She had to make him learn to do things differently and so she used her forced foot worship fetish to dominate him. He was in pain and he realized that he was not trying hard enough. He resorted to change that immediately.
Goddess Kiffa had walked along the street in her bare feet and then she got back home and she asked her slave to lick her feet clean as she did not want to go to the bathroom to clean up. And when he did not do it as well as she wanted, she would slap him in between her eating chicken wings and drinking her wine. He licked them her way after the slaps.
