The main character helps out at a relative's hot spring hotel during winter vacation. One day, he runs into a big-breasted customer in an open-air bath outside of business hours. This is a book about squeezing out the breast milk accumulated on a long trip, drinking breast milk after taking a bath, and enjoying breast milk to the fullest.
