Goddess Kiffa wanted to find out whether this guy was a good lover. So she had to test whether he could lick her and give her multiple orgasms. He had to lick her feet first for her to know that. When she realized that he did not have good licking skills, she had to make him learn but first, he had to endure being ball and dick crushed a little to give him the right motivation.
Goddess Kiffa was mad at her man and she did not want to talk to him. But since he did not know how to pick up clues, she knew she had to do something to him without talking to him. So she went outside and she soiled her bare feet and she got back into the house and she made him lick them clean. And she did not talk to him but rather used that as communication that things were not ok.
