In Part 3 of this erotic story, the young and dominant Mistress continues her relentless abuse of her older, submissive lover in the intimate setting of a toilet. As he kneels before her, awaiting her next command, she casually reaches back and grasps his hair forcing his mouth towards her gaping rectum. "Here boy," she growls, "eat my shit." Her words are a commandment as she begins unloading a massive stream of steaming, liquid turd into his waiting mouth. Her assailant struggles against his bonds, but to no avail. He can't escape the disgusting mixture of feces and saliva that she forces him to ingest. It fills his mouth, coats his tongue, making him choke and gag on the foul taste. Feeling overwhelmed with her lover's struggle, she pulls her mouth away and peers down at him with a sadistic grin. She waits for him to come up for air before continuing her assault. Once he regains some semblance of composure, she forces his face back into her rancid orifice. "Suck it clean, you pathetic piece of shit," she says pushing his head deeper into her rectum. With every ounce of energy he has left, he obeys her command and begins working his tongue around her tight anus, meticulously cleaning every inch of her rim. As he gets more comfortable with the task, he takes in more of her waste and swallows it down. He starts to grow used to the revolting sensation of her shit filling his mouth and the horrid taste begins to fade into a dull ache. As she continues to grind her hips against his face, she releases an enormous turd coated with her anal juices. This time, she doesn't force him to eat it. Instead, she watches as he struggles with the overwhelming urge to gag on the fresh load of excrement. His face is flushed and his eyes filled with humiliation, but he cannot disobey her. Finally, after what feels like an eternity, she pulls her ass away from his face and stands up. She towers over him, a look of satisfaction on her face. He is exhausted, spent from the constant abuse and humiliation, but he knows there is more to come. "Get up, slave," she snarls, "we have more work to do." Despite his weakened state, he finds the strength to stand and follows her out of the bathroom, wondering what twisted torment she has in store for him next.
