In a private schoolroom, a slave is subjected to extreme humiliation by four Mistresses. He is severely whipped and crushed by their sharp high-heeled shoes. One Mistress defecates on the floor, forcing him to consume it and drink it down with her fresh urine. The Mistresses are unyielding, and the slave is left with no choice but to obey their commands. This is a story of absolute submission and degradation.
