Madame Marissa and her friend did not like how this girl looked down on them. She felt like she was superior to them and that they were not in her class and did not even deserve to talk to her. They were not interested in doing anything with her except for the fact that she tried to show them that she was superior to them. The mistresses could not let her do it so brazenly in front of their faces so they beat the shit out of her and crushed her tits by trampling and stomping them.
