Lady Scarlet realized that this guy was a conniving bastard and she did not want any part of it. She wanted to deal with someone who was straightforward and this guy was not. So he had to be punished. The mistress used her hard slaps on him after she had caged him. He was had cramped muscles and could not defend himself against her hard and cruel slaps. He stopped that habit.
Lady Scarlet was so angry at this guy that she slapped him sadistically. She did not care what he felt as she punished him and she went as far as torturing him like never before. He tried to plead with her for leniency but she ignored it and she humiliated him with more slaps and she spat on him. The guy knelt down as she humiliated him and slapped him.
Lady Scarlet wanted her slaves to learn about pain management. That is why she chose to slap them everyday until she realized they were able to take the pain without flinching. The mistress would normally tie them up so that they would not block her slaps. And after a few weeks, she realized that their pain threshold had gotten higher and they did not respond to her slaps with fear like they used to.
Lady Scarlet was dying to send a message to this loser. This is because he did not listen to her and she was not going to let a slave do that to her. So she used her slap fetish to dominate him. As she landed hot slaps on his face, he realized that she was serious in wanting him to change and reform himself. He got the message loud and clear.
Lady Scarlet did not like how fast her lover came as she did not get satisfied with his sex. She was so pissed at him that she decided to do something about it. The mistress chose to tie him and facesit on him both as a punishment and also as foreplay. She would also rub her clit and her pussy on his face until she came. It had the added advantage if sending him a message.
