A small family-run inn located in a hot spring town. At this inn, 48-year-old proprietress Misato runs the daily operations with warm and gentle charm. One night, when her husband is away, she becomes the target of a man's advances. With elegant features and a graceful aura, her slightly soft, supple body boasts well-rounded, squeezable buttocks. When she's asked to give a massage, he seizes the opportunity to tease her body. She whispers, "No... I can't...", yet beneath her words, her body instinctively reacts. Late at night, he sneaks into her room and quietly lifts her yukata without waking her. Her slightly darkened, sensitive nipples become visible—when touched with fingers, they quickly grow hard. Her lower body reveals mature, well-shaped buttocks that respond truthfully even in sleep as he caresses them with his palms. Unable to resist, he presses his cock into her mouth, and reflexively, she takes it in deeply, proving her pent-up desire. Juices leak from her pussy as he stirs them with his fingers. The proprietress wakes, murmuring, "Sir, what are you doing... this isn't right..."—but her voice no longer carries resistance. Though she keeps saying, "No... no...", she can't resist the long-forgotten sensation, pleasure spreading throughout her body. She swallows his cock deep into her throat, confessing, "I've wanted this..." and can't stop. Her soaked pussy spreads wide as she takes his cock inside, grinding her hips on her own, climaxing intensely again and again.
