Nao and her husband inherited the tradition of bathing together from their parents' house from their old father-in-law. However, the two of them were very busy, the couple's time was running out, and life just passed them by. One day, just before the shop closed, the usual Takahashi, who always came, worked in a public bath. Nao stayed close because she spent more time with him than her husband because she was lonely. Her body, remembering the pleasures of lovemaking while feeling guilty, leaked out a gasp every time he thrust his meat stick in the large communal bath.
