Goddess Mia was angry at her slave as he had not been on his best behavior lately. She had to warn him and she did it with her socks. The mistress used her sneakers as well as her socks to threaten him. He was told he would be made to lick her socks and her sneakers and she would also trample him. He got scared of that and he changed.
This mistress had a new slave and she wanted to instruct him and to find out how well he took instructions. So she asked him to lick her stinky socks. She was also checking for his obedience. She then gave him instructions on how she wanted her socks licked and she was glad he did everything her way so she did not need to torture or punish him any further.
