From the day married woman Kaori steps into the soapland, the manager begins personally training her in various techniques. Tasks like scrubbing with a brush, vaginal douching, sitting on special chairs, and using periscope devices may appear to be mere cleaning duties at first glance, but gradually Kaori finds her senses stirred. What seems like work soon feels more like a place to satisfy her own desires. Further experiences await her—full-body lotion massages on the mat, intense sex, and even ménage à trois encounters. Before long, Kaori's mind and body are completely consumed by the world of the soapland.
