This guy was such a poor listener that lady Despina felt that she needed to humiliate him. And she did not hesitate to do it because she felt that it was important to punish him so as to change him. He was therefore turned into a spit slave and he had to lick her saliva as well as endure the domination and humiliation that came with it. He knew it was easier to be a good listener than to be humiliated.
