Daisuke, 56 Years Old, Head Groundskeeper (FOR A LITTLE MORE MYSTERY, OR TO SKIP SOME MENTIONS OF ENEMAS AND THE SMELL OF BOWEL MOVEMENTS, SKIP THIS CHAPTER USING THE OPTION BELOW!)

Daisuke nods to the headmistress on her way out. She smiles a wry smile, and nods back.

Five minutes later, using his master key, he unlocks the door to the her office. He gives the windows and clear surfaces a quick wipe, and then heads to the only other door in the room - to her private en-suite.

Inside, a welcome and familiar sight greets him. A naked butt, sticking out of a perfectly sealed hole in the bathroom wall. Beneath it, two similarly trapped ankles and feet. The Japanese characters for the words 'Filthy' and 'Stinker' have been inked on the sizeable buttcheeks, along with a biohazard symbol. It is surrounded by various chemicals and cleaning equipment.

"Time to clean the toilets... and give you your daily enema." Daisuke says to the butt, knowing full well that it can't hear him.

He looks at the photo of the face pinned to the tiles above the pronounced posterior.

He doubts the woman in that photo still has that calm expression on her face.

"It should count itself lucky." He again speaks into the silence. "At least it can still eat with its hands."

Removing the sinkhole-plug-themed buttplug that's been filling the butt up all day, he replaces it with the enema nozzle. While its belly fills up with the soapy solution, he wipes the ass down with the cloth resting on the top, and uses the spraybottle of cleaning fluids sitting on the other side to clean the actual toilet opposite it, and to sanitize all the urine that it's pissed out onto the floor over the course of the day.

Pinned to the wall to it left, a lab coat, blouse, skirt and panties remain pinned up, as they have all week. As usual, he can't resist whipping out his cock, and rubbing it up and down on the fabric, letting just the tiniest amount of precum stain the clothes. Not enough to properly leave his scent in the room, but enough to make him feel like he's left his mark of ownership on them.

Next, once the enema is complete, the nozzle is removed, and replaced with a large hollow plug. This plug has an in-built tube, which runs through a hole in the wall. He watches with glee as moments later, the butt's disgusting daily bowel movement makes its way down the tube and through the hole, where it flows into some guttering that runs along the inside of the concrete prison, just outside of arm's reach. Some of it will flow all the way through to the drain at the other end, but most will remain in the guttering, filling the small space with its stench.

"I'll be back in the morning to flush it all down with water, as normal." Daisuke once again speaks to the unhearing butt. "Until then, enjoy the smell of your own farts."

Once the butt has finished involuntarily expelling its enema, Daisuke replaces the original butt plug. Finally, he checks that the tubes providing fresh water and a nutritious sludge are still operating correctly, and that the supply levels have gone down by about the expected amount.

"Meat Toilet One is still fully functional." He says to himself, before turning off the light and leaving for the night.
