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.
There is no better punishment to Amy than teasing her slaves. She enjoys putting her naughty slaves in their cages and putting on sexy lingerie and heels. She enjoys the way they squirm when they see her in a pair of thongs and stockings. She is happy to put her ass in their face. She loves knowing they want to lick her from her feet to her ass. She enjoys putting her high heeled feet in their face and teasing them because they can't get to her.
