Madame Marissa did not like what her boyfriend had done to her friend. He had spoken rudely to her friend and she did not like that. She wanted him to treat her friends better so she punished him. She made him smell and even chew her smelly and sweaty socks. She trampled his face with her dirty feet and made him apologize to her friend. Then she warned him never to do it again.
Mistress Cindy wanted to humiliate her new slave. She did not want to go nuclear on him given how new he was. She wanted something light that would send a message to him not to get too comfortable. She made him lick and smell her sweaty and smelly feet and told him not to mess with her as she was capable of worse things than having her feet and her socks smelled.
