Mistress Haruki elegantly entered the restroom, contemplating which seat to occupy first. She approached the chair and eased herself down onto the cleaning slave, ensuring her ass cheeks covered nose and mouth. The slave extended its mouth and nose, eagerly burying its tongue deep into the mistress’s crevices. The mistress sighed in pleasure, acknowledging the slave’s thorough training. The moment of truth had arrived. She had been saving her reward for the shit slave, and now was the time to deliver. Positioned over the square hole, she released a warm, foul-smelling fart, allowing the slave to inhale the potent aroma. The slave opened its mouth wide, eagerly accepting the putrid waste streaming from the mistress’s anus. Her anus expanded, releasing six inches of soft, shapeless, sticky shit into the slave’s mouth. The slave chewed diligently, ensuring no morsel was wasted. The mistress then positioned her shitty anus over the slave’s face, allowing the first slave to clean her thoroughly. Her mission accomplished, Mistress Haruki left, satisfied.
