Mistress Medea knew this guy was not gullible but it was her intention to make him one. And she did it by teasing him with her hot body and the way she was seductively dressed. He could not resist her and that is how he fell for her trap. She managed to make him humiliate himself for her sake and she had a great time watching him do it without any clue that he was not turning her on but rather humiliating himself.
