Mistress Bastienne set out to give this guy the experience of a lifetime. She felt that he needed to be dominated and she did not hesitate to do it. The mistress used her scat fetish to do what she needed to do to him and that is why she not only shit on him, but she had a dildo on his balls. He cried and begged her to stop but she did not.
This mistress was out to torture this guy and teach him a lesson he had never been taught before. That is why she opted to use her shit as butter and she made the guy eat it. He was shocked by the extent of her cruelty but she was moved by his pleas. He had to do all that she asked him to do and that is how he learned his lesson.
When this man proved to be a pain in the ass, mistress Bastienne had to make him regret his choice and he did after she dipped his face in her ass. He was shocked as he did not expect that. And it had never happened in his life. The mistress laughed as she humiliated him and she knew that he had gotten the message and that he would not mess with her again.
This guy came too early. He had premature ejaculation and she was pissed at him and she felt that he had to learn to control his cum so that he did not cum too early or too late. He had to learn how to satisfy his sexual partner and so she used her shit to pass the message and to make sure that he had a reason to make the required changes.
