When her father-in-law's health declines, Kanna moves into her husband's family home to care for him. She devotedly helps him eat and cleans his body, but being touched by a young, beautiful woman—even as part of his care—gradually restores his vitality and lust. The moment his son looks away, he spreads Kanna's legs, buries his face in her pussy, and laps up her flowing juices. As she stifles her voice and trembles with pleasure, he uses his newly revived cock to rape her.
