Three months after moving into her husband's family home, the aging house required urgent maintenance. Tired of her husband's clumsiness, wife Misato decided to ask her skilled and assertive superior, Sagawa, for help. With Sagawa's assistance, the house was quickly restored, and Misato felt relieved. However, her husband was injured during the work and rushed to the hospital. Seizing the opportunity, Sagawa, who had secretly desired Misato, forcefully overpowered her. Unable to resist his persistent and lewd advances—so different from her husband—her body eventually succumbed, climaxing against her will.
