Mistress Saskia did not want to deal with this guy because she felt that he lacked discipline. She had give him a chance but he disappointed her. That is when it dawned on her that he needed to be punished and she had to do it the best way she knew how. He cried and thought that she would be moved by it but she was not moved at all.
Mistress Saskia did not like how this guy had challenged her. He thought he was better, smarter and stronger than her but she knew he was not. So she agreed to the arm challenge and she won it. After she did, she had to make sure that she dominated as well as degraded him and this was done by ballbusting him. He never forgot it and learned his lesson the hard way.
