We target naive young ladies who have just come to the big city of Tokyo for the first time, and have them do some super-erotic work that shouldn't even be part of their job. They thought it would be an easy job at a health spa, but the tasks they were given one after another were so embarrassing that they couldn't even talk about them... They were supposed to be doing a back wash in the mixed bathing service, but when they noticed, they were also doing dicks!? But girls who don't know the city will believe it!
