Shiori is a married woman who lives a peaceful life with her husband Kenichi. Although she is living a happy married life, her husband and I have been having less and less sex lately, and she has been feeling unfulfilled. One day, while out with Kenichi, she happens to meet Kenichi's junior colleague, Takao Yamaguchi. Later, when the three of them were eating hotpot together, they found out that Yamaguchi was working as a dispatched masseuse. "If you don't mind, I'd like to give it a try?" The massage started out light, but every time Yamaguchi's big, warm hands touched her skin, her body gradually began to heat up. From that night onwards, Shiori couldn't stop thinking about Yamaguchi's fingers. Before she knew it, she was calling Yamaguchi without her husband's knowledge, and secretly requesting him to come to her for a massage... "It was supposed to be a massage, so why...?" During the treatment, every time Yamaguchi's skillful fingers traced over her sensitive areas, Shiori's body reacted involuntarily. Before long, her addiction to the massages turned into a longing for Yamaguchi.
