Goddess Nemesi needed to scare this guy and she did it in the way in which she wanted. That is why she chose to use her spit fetish to teach him a lesson and it had to be a lesson that no one ever taught him. He could not believe how it all went down but he knew that her word was law and that her wishes had to be his command literally.
Goddess Nemesi wanted to choke this guy and she was also interested in turning him into a spit slave. She did this without thinking twice about it. She had to make sure that he learned his lesson the hard way and that is exactly what she did to him. He cried and he begged her for mercy but she ignored him and did not show him any. He had to toe the line.
Mistress Nemesi wanted to correct this guy but she could not because he did not like being corrected. She had to punish him for it and she ensured that he learned his lesson in a painful and humiliating way. The mistress did this by having the guy kneel down and she spat on his face. The poor guy did not see it coming and she loved everything that he did.
