A young wife named Yuki, who is leading a happy married life with her husband. Her husband's superior, who takes him out every night saying "drinking is also part of the job," is a sales manager. One evening, while Yuki is confiding her dissatisfaction with this sales approach to her husband, she is overheard by her husband's superior. Frustrated by this unreasonable situation, the superior forcefully violates Yuki. From then on, regardless of whether her husband is present or not, Yuki continues to be violated, and eventually, as her body is developed, she is unable to resist and becomes dominated by her husband's superior.
