This guy misquoted mistress Sofi so badly that she could not let it go. She had to punish him so that he learned to quote people properly. He had sort of ruined her reputation because of how badly he had done it. It gave people a very wrong impression of her and she was not impressed by it. So she slapped the shit out of him to make him be careful next time.
No matter what mistress Sofi did, this guy did not respect her. She tried to ignore him but she felt that he was too much and she had to sort him out. She chose to use her faceslapping femdom to torture him. So she forced him to lie down and she slapped the crap out of him. His face was hot, red and in a lot of pain. And he never disrespected her again.
Mistress Sofi is the kind of person you do not want to mess with as this guy came to learn. And that is why she had to make sure things changed. The mistress faceslapped him after she had facesat on him because she felt that facesitting on him had not done what she had intended for it to do to him. But after the slap, she knew he had gotten the message.
When mistress Sofi and her boyfriend agreed to spice up their love life, she found the chance to try something she had been dying to try for a long time. The mistress wanted to try BDSM and especially the pain part of it. She chose to slap him and she tried to make it as sexy as she could. It was painful for him but she was surprised at how he appeared turned on.
