Mistress Anfisa likes slaves who can handle her. She does not like weak ass slaves. She likes those who are able to endure what she throws their way. But in return, she compensates them handsomely. She rode her new slave like a pony and whipped him from behind. She pulled his hair and abused him to test what he could and could not handle. That was the main determinant of his compensation.
Teodora and Joss wanted to gauge the pain threshold of their slave. They called him to where they were. They were dressed in bikinis and looked sexy. Then they trampled him with their high heels. They wanted to find out what effect looking sexy while trampling him would have on his pain threshold. It was an interesting study and they had lots of fun at the expense of the slave.
Madame Marissa wanted to punish her slave deep in the forest where she knew no one would hear his cries of pain. She took him there and when she reached a place she knew was good for what she wanted to do to him, she made him lie down. She then used her shoes to trample him and punish him cruelly. It was a punishment but it was fun for her.
Mistress Narziss is as cruel as anyone you have ever seen. The only difference to many mistress is that she does not punish a slave for nothing. And she does not use flimsy reasons either. She waits till a slave messes up before she humiliates him and punishes him. When her slave messed up this time round, she whipped him after tying him to the stairs. She left him with his back all red and in pain.
