Mistress Anna did not like her slave's work ethic. She had to make sure it changed. She did not want him to get used to his poor work ethic. So she changed it by cruelly humiliating him. She made him lick and smell her ass before farting on him and finally shitting on him. She made sure he ate all her shit and swallowed it. She told him she would do it every time till he improved his work ethic. He improved it in record time.
