The married woman, unsatisfied with sex with her husband, applied the day after their wedding anniversary. During her school days, she was active in the track team, and it was her past experience with discipline that awakened her masochistic tendencies. She looks strangely pleased on the train, seemingly eager for the training to begin. On the train, she reads a pledge while receiving blowjobs and fondling. In the forest, remote-controlled and exhibitionist training takes place, and at the inn, she happily accepts the man's cock during intense sex scenes. The trip's surreal atmosphere awakens the promiscuous nature hidden deep within her, revealing a new side of her personality.
