While staying overnight at a ryokan with her husband, he falls asleep early. Beside him, the wife begins receiving a massage. Nervous at first, she's told it's part of fertility treatment. The massage starts around her buttocks and the area near her slit, provoking sensitive reactions. Gradually, fingers slip inside her. Unable to resist the explanation that her entire body needs massaging, she finally accepts the masseur's cock. With her husband sleeping right beside her, the intense treatment continues, culminating in a creampie guaranteed to result in pregnancy.
