This mistress loves to scare and that is what she did to this loser today. She felt that it was important to teach this guy a lesson and she did so in a way that he would never forget. She loved how the guy cried and begged her for mercy but she was not moved by any of what he did. She had to have her fun at his expense and to scare him.
Mistress Cassie felt that her ex needed to stop the nonsense he was used to doing. She was not ok with how he did things and she felt that she had to teach him how to act. The mistress also needed him to stop contacting her and that is why she chose to make sure that he watched her take a shit. As he did, he saw a side of her he had never seen before and he changed.
Mistress Cassie had a jealous classmate and she did not like that about him. She felt that it was important to deal with him because they were not competing for anything. He had to learn to do things the way she wanted and that is why she went out of her way to shit on him and make sure it was so disgusting that he would have no choice but to change.
