Genkei, the bald slave, chuckled as they placed the mouth expander on him. His opinion was all that mattered, as he was a reliable human toilet. The mistress sat on Genkei’s mouth, releasing a lengthy, foul-smelling fart, which tasted divine to him. The mistress had been drinking and her stomach was upset. Her noisy turd plopped out, and she had difficulty getting it all out in one piece. Half of it landed on Genkei’s chest, making him grin as he missed it with his mouth. His mouth was full of chewed-up poop, with a brown exterior and yellow, fibrous insides. The delightful shit tasted bitter and sweet, and Genkei craved more of the soft and sticky feces. The mistress used tongs to play with the poop in Genkei’s mouth, making him giggle as the tongs crushed and twisted the feces, releasing even more foul flavors. It was an excellent day to be a human toilet.
