Set in Hakone Onsen, SOD's new graduate female employee Eri Kataoka of the first-year production department takes on a famous project for her new hire training: entering the men's bath with just a towel. Her missions are to 'lick all over the male customers' bodies' and to 'have male customers rub their penises all over her body.' What was supposed to be just a camera check turns into a chaos as general male customers barge in, surrounding her with their penises! Will she complete the mission? Even insertion!?
