Five soapland girls on a hot spring trip. They encounter boys having a club activity sleepover at the inn. The girls, in high spirits, expose their naked bodies to the boys who are cleaning the open-air bath. The boys can't hide their excitement at the sight of the girls' naked bodies. The girls further tease and seduce them (extreme close contact, let them touch their breasts), and the boys eagerly caress their breasts, causing the girls to unexpectedly become aroused! Unsatisfied, the girls plan to bring down the boys using soapland techniques‥
