Yui lives with her husband in an old apartment complex. Next door resides an elderly man, Takuro, who lives alone. Having always been close to elderly people, Yui actively takes care of him. One day, while cooking together, Takuro suddenly embraces her, saying she resembles his late wife. He spreads her legs, pressing his face into her crotch. Though Yui desperately resists, her body begins to respond to Takuro's skilled tongue. Unable to restrain himself even in front of her husband, Takuro's supposedly lifeless manhood stirs back to life, pulling Yui deeper into his grasp.
