Write a story about a woman named NAME_1 and her boyfriend NAME_2. She is dominant and talks in a mean way to him sometimes. One evening in bed she suddenly undresses and starts to defecate on the floor. Then she commands him to take off his clothes and sit on her pile of shit. He does what she says. He sits down on her shit. Some of the shit is entering his asshole. He starts to press more and more of her shit into his own ass. That feeling was so perverted that he had several orgasms. Use direct speech.
