At Murakami Clinic, a urology practice, young resident doctors temporarily lodge with Dr. Murakami Ryouko, a lewd older woman with big tits who runs the "Lewd Old Lady’s Boarding House." As daily medical routines intertwine with chaotic shared living, the residents and patients become entangled in erotic, depraved affairs. Amid an unsettling atmosphere, aggressive seductions, intense sexual encounters, and female ejaculation unfold. The solemnity of medical practice starkly contrasts with the unruly, lust-driven household, creating a provocative clash of discipline and desire.
