Marina and Uchimura, who work in the same office, have a double affair relationship in which they seek their bodies while holding a family with each other. The two people who piled up Aise while avoiding the eyes had the same desire. "I want to forget everything at once and spend all my time in SEX." An affair trip called a business trip planned to make such a dream come true. Then, on the day of the meeting, the two met at the station, changed from suits to plain clothes, boarded the limited express train, and as soon as they arrived at a remote inn, they scrambled for their lips.
