In the Edo period, women who provided services such as scrubbing bodies at bathhouses were called "Yuna." Over time, however, this occupation gradually shifted toward offering sexual services, eventually leading to repeated government bans. This film presents a unique visual experience: mature women revived in modern times, gently yet provocatively washing men's bodies with meticulous care. The charm lies in the milfs' delicate attentiveness, the beauty of their mature, sensual figures, and their lewd, skillful hip movements. They handle the male body thoroughly and boldly, as if cleansing it with deep affection and devotion.
