A work centered on diaper usage and feelings of shame, comprehensively documenting every step—from putting on diapers to real-life usage scenarios and changing procedures—in a manual-style format. Features numerous realistic situations such as accidentally leaking during a live stream or urinating while sharing an elevator with others. Offers detailed multi-angle views of excretions inside the diaper. All performers wear transparent diapers, and this installment includes diaper change scenes starting from baby wipes. Packed with humiliation and fetish elements, this title is a must-watch for diaper enthusiasts. Four performers appear, including a girl live-streaming online who wears a diaper and continuously urinates, then defecates while pretending to remain composed. Scenes shift to diaper changes, where careful attention is given and their expressions gradually return to normal. A husky-voiced girl tests defecating in a stalled elevator, personally demonstrating the diaper's effectiveness, while awkwardly laughing through this rare experience. Beautiful Misaki also appears, demonstrating soiling while sitting in traditional Japanese style. Due to loose fitting, holy water drips from the side, and she comments, "My poop is floating in my pee," as she releases an extremely thick log. The main performer of the Excretion House also appears on camera.
