Mistress Gaia did not like the bad behaviors that this guy had and for that, he had to be taught a lesson and he had to be punished. That is why the mistress felt that the best thing to do to him was to invite her friend and get her to help her in fisting the guy. He was shocked at what they did to him but he was powerless to do anything about it.
Mistress Minky did business with this guy and she trusted him and did everything in good faith but she later came to find out that he was conning her. She was so pissed that he could do such a thing and she punished him so that he would not feel the need to do such a thing again. She made him bend over and she ass fisted him before ass fucking him with a strapon.
Mistress Jennifer wanted to send a strong message to this loser. She did it using her fisting femdom. She turned him into a fist slave and she forced him to bend over and take her fist in his ass. It was excruciatingly painful but she got what she wanted out of it. She was able to send a message to him and she knew he had gotten it and would not piss her off again.
