Saki’s historic hot-spring inn was once among the finest in town, but its glory has faded. Travel-agency president Kita proposes reviving it by using the beautiful proprietress’s magnificent body to satisfy male guests and earn five stars. Shocked but out of alternatives, Saki accepts. A powerful local customer may decide the inn’s fate, so the young proprietress pours everything into erotic hospitality, healing both heart and crotch with premium full-body service.
