After graduating high school, Miku moved to Tokyo and began working as a "Piss Home Delivery Lady," initially shy and timid. At first, she felt extremely embarrassed urinating in front of customers, but seeing the men's excited reactions awakened a hidden perverted side within her. Gradually, she begins to feel this is her true calling, becoming deeply absorbed in her work. A variety of piss play unfolds—direct drinking, facial bukkake, pissing on clothed bodies—and delivering fresh urine becomes her daily routine. Once again today, as she steps into men's homes, Miku feels immense satisfaction in her job.
