Wani no Yu is a public bath located in the downtown area, a little away from the entertainment area. Wani no Yu was loved by many people after the war, but now that houses with baths have become commonplace, the number of users has rapidly decreased. Meanwhile, the shop owner hires his married wife, Hitomi, and starts ``Akasuri'' in the men's bath to attract customers. Hitomi shamefully licks herself in the men's bath full of cocks, but she gradually becomes frustrated.
