Kazuo was a little jumpy when Cha, his mistress, stepped into the bathroom. With her undies down, he could see the flawless arc of her butt, and her taut asshole, which he licked and cleaned daily. Squatting slightly to get a better aim, her release began with a musty fart that covered the entire bathroom. The warm air was strangely erotic as she sat down and made sure that her anus blossomed in front of the Kazuo, whose mouth was already as open as it can be. Her shit flowed out in a slim column, and snaked down his tongue. She tasted bitter and fetid, but he kept gobbling her shit up like a maniac. Today was a good day to be a human toilet.
