Mistress April did not want an assistant who did not know how to do his work properly. And when she tried to correct him, he did not seem to like it and would even take offense. She was so pissed at that sort of behavior that she used her shit to make him drop it. The mistress also added a little whipping while her assistant was naked. It worked wonders.
This guy was a con and he thought that because of his advanced age, no one was going to do anything to him. He was wrong and when he conned mistress April, he regretted it as the mistress used her shit and her pee to punish him. He had never received such a punishment and that is how he knew his conning days were over as he could not stand such a punishment again.
