I secured my slave to the wall, his mouth left agape, and utilized it as a receptacle for my excretory needs. He had no choice in the matter, reduced to a mere human toilet, existing solely to serve my digestive whims or face harsh punishment, even starvation. After the initial sizable log, I compelled him to clean me, only to find myself requiring his services once more. This time, I defecated directly into his mouth, all the while he performed his cleansing duties. Such is the wretched fate of a human slave, subservient to my every bowel movement.
