A sales representative and his superior, Erika Iikura, collaborate on a promotional project to boost sales of a new swimsuit line. Last year's sales plummeted due to freezing temperatures, so this year's success hinges on a flawless presentation. The team had selected a model to showcase their standout swimsuit design, which had already received high praise from staff. However, the model suddenly canceled at the last minute, forcing Department Chief Erika Iikura to step in as the emergency swimsuit model. The presentation concludes successfully, leaving everyone relieved—yet after seeing their boss in a swimsuit, the male employees become deeply aroused, lost in vivid fantasies, consumed by desire.
