Mistress Valeria and mistress Selena were enjoying themselves when this girl slave tried to join in on the action. They were making out and she wanted to join them and have a threesome with them. But they were not quite ready for her yet and so they made her lick their feet as they made out. She had to earn the spot on having any kind of sex with them.
These mistresses came to understand that their friend had been behind their string of misfortunes because of her loud mouth. They had to take care of her and make sure it never happened again and that is why the mistresses chose to trample her and kick her besides stomping her. She was in the pain of her life but the good thing was that she learned her lesson and was never a loudmouth again.
