Lady Kacy was trying to do a project with this guy but she was pissed that he was irrational and she did not want such a thing to happen again. That is why she chose to use her fist to do it. He was in pain as he had never had such a thing done to him. In fact, he had never had anything up his butt before and it was torture.
Lady Kacy Kisha did not like how this patient made her work difficult and spoiled her mood. It affected how she related with other patients and that is why she liked to see him last. But she did not want it to continue so she fisted him in the ass and he screamed out in pain but she gagged him so that no one heard his cries. He never made her work difficult again.
Lady Kacy Kisha and her friend used their fisting fetish to achieve what they wanted. This guy was being difficult and they had no choice but to torture him. He had to learn his lesson painfully and in a hard way. He did not know what they had in store for him but when he saw it, he cried and begged for mercy but none was shown to him. He had to face the music.
