Goddess Suzy needed to scare the shit out of this guy and that is exactly what she did. The mistress had to make sure that she dominated as well as tortured the guy so that he would learn to fear her. She made sure that he was in pain as she crushed him and he cried as she did her thing. He never tried messing with her as he knew what she would do to him.
Mistress Suzy could not comprehend why her slave was arrogant to her. She was good to him and she tried her best to forge a good relationship with him but he did not reciprocate.

So the mistress went for his neck because that would scare the shit out of him. It did and the punishment worked as she wanted it to as she got the info.
