Mistress Gaia was not happy with how she lost money on the advice of this guy. She was pissed and she had to make him pay back her money. She forced him to lick her feet which she made sure were sweaty and smelly and then she told him she wanted her money back and that if she would not get it, he should be prepared for something worse than what she had done to him.
Goddess Ice Era knows that her slave is a loser and she wanted to make sure he grew out of it. She did not want a loser for a slave anymore so she humiliated him everyday to make him strive to be better and to be different. Se forced him to lick her socks and smell them. She would even choke him by inserting her foot into his open mouth.
