Kei was confined securely under the tiles, eagerly waiting for his mistress or one of her friends to arrive and reward him for his hard work. Soon enough, his mistress arrives, pulling down her soiled underwear and aiming her putrid anus towards Kei’s mouth. She takes pleasure in defecating on this human toilet, especially when she hears Kei chew and swallow her feces. She has been holding her excrement for two days, and the dark brown feces has hardened and molded to her colon. The small flaps every few centimeters emit a powerful stench, reminiscent of rotting meat with a hint of acidic fruit. Kei closes his eyes and opens his mouth wide, allowing the large feces to fall perfectly into his mouth, resting wetly on his tongue. She squeezes and cuts the feces, but not before a large section of it plops lazily to one side. Kei chews vigorously, tasting the bitter, rotting excrement and remnants of undigested fruit. His mistress’s feces are highly acidic, and Kei feels fortunate to have received such a valuable feces so early in the day. After relieving herself, his mistress lowers her buttocks and genitals, cleaning herself using Kei’s nose and mouth. Small bits of excrement and some genital fluid smear Kei’s face, and he struggles to keep quiet as his throbbing erection punishes him from beneath the tiles.
