Yukari lives with her daughter and son-in-law, doing her best to maintain harmony between the couple. Lately, however, she's been troubled by her daughter's increasingly harsh attitude toward her husband. One evening, after her son-in-law compliments Yukari's cooking, her daughter becomes upset, leaving an awkward tension in the air. Late at night, Yukari finds her son-in-law sitting alone in the kitchen, visibly distressed. When she asks, he reveals a deeper issue—his sexless marriage with her daughter. Moved by his pain, Yukari whispers, "I'm sorry for my daughter. Just tonight, I'll make it special for you," and gently strokes his cock. A few days later, Yukari asks her daughter about having children, but the question is quickly avoided. Later, while delivering laundry to the couple's bedroom, Yukari sees her son-in-law lying down and turns to leave—only for him to suddenly pull her into a tight embrace from behind. "No, that time was an exception," she protests, but he silences her with a deep kiss and begins caressing her body. Though she resists, her body responds, her panties dampening visibly. As he spreads her legs and thrusts inside, she feels a surge of pleasure—just as her daughter calls out for him from afar. Relieved, Yukari catches her breath, yet realizes her body still aches, unsatisfied.
