When Haruna's husband collapses, he is admitted to the hospital where she works as a nurse. Already exhausted from balancing her shifts with caring for him, she learns that Fujisaki, her former teacher, will share his room. Seeing how mature and attractive Haruna has become, the sexually frustrated Fujisaki can no longer suppress his erection and pushes her down. Years of loneliness have left him insatiable, and one assault is nowhere near enough as he continues demanding her body until pleasure breaks down her resistance and leaves her completely obedient.
