Mami takes a long break from work and goes back to her hometown, a public bath, where she helps out. She wants the bathhouse to be as prosperous as it used to be, so she comes up with the idea of using the skills she gained as an adult video actress to help boost it. She uses her G-cup breasts and techniques to soothe the lower halves of the customers, but ends up overdoing it and the bathhouse becomes overcrowded with customers!
