Ichika was married and left her job three years ago, but after her husband lost his employment, she returned to work in the same department. Shimo-kawa, who used to be Ichika's subordinate, is now her superior, reversing their positions. Shimo-kawa had secretly loved Ichika since before her marriage, and now uses his authority to devise a plan: during a business trip, he lures her to a hotel and rapes her. Freshly reinstated and desperate to keep her job for her husband's sake, Ichika is trapped in a private room and subjected to a degrading sexual assault. As it unfolds, her black pantyhose gradually become soaked.
