Lady Sandy caught her slave watching porn on his phone and she was disgusted. She had warned him not to do so and since he had disobeyed her, he had to pay the price. That is why the mistress took the phone from him and she crushed it with her high heels. He had to learn his lesson. He never masturbated again as he knew what would happen to him.
Lady Sandy wanted to spite her boyfriend because she knew he was a clean freak. So she took a banana and she crushed it on the floor of the house and she left it there. She then rested her feet on the couch without cleaning them first. He was so pissed that he got a migraine just by seeing what she had done. And that is how she achieved her aim.
