Mistress Lilli knows how to faceslap and she is good at it. She wanted to show her sister how it was done and so she had to make sure that she dominated this loser as her sister watched. She did it while the guy was tied up and after she had slapped him severally, she asked her sister to also give it a try and she did. She loved it.
Mistress Lilli wanted to interview this guy but he did not want to talk to her and she did not like it. She had to punish him for it and she used her faceslapping fetish to make him agree to the interview. He was tied up and slapped cruelly and he realized that it was easier to do the interview than to be slapped and humiliated the way she was doing to him.
