Princess Serena was not going to let her slave disrespect her. She is the kind of person who does not take disrespect from anyone. So she wore her pink high heels and her hotpants which she normally uses to flirt with guys she wants to financially dominate and she used them to humiliate him. She then got the loser to lick her heels as she warned him never to disrespect her if he did not want his balls and his cock to be trampled by her heels.
Mistress Felicia came from the gym and she found that her slave had not prepared the juice that she had instructed him to make for her. She was mad about it as he did not have much to do besides that. She had to make sure he learned his lesson and never ignored her instructions again. So she made him lick her sweaty feet as well as her smelly socks.
