Mistress Nica was paid to get answers from this guy and she had to ensure that she got them all. She did not want to let the guy get away with what he had done and so she used her skills to get him to talk. She fisted him and since he had never been fisted, the pain was out of this world and she got what she wanted from him.
This girl had been lying about mistress Pina and mistress Abby. They did not like it and they had to punish her for it. That is why they went ahead to use their fisting fetish to control and to dominate her. She cried as they did it to her without arousing her first. It was painful and she cried but they did not stop what they were doing to him.
Goddess Nemesi felt that this guy did not take things the way he was supposed to do and so she used her fisting fetish to dominate as well as degrade him. She used her fisting mistress fetish to do it and by the time she was done with him, she had managed to not only pass the info she wanted, but to get his concurrence on what she wanted to be done.
