A man walking through a quiet hot spring town in the rain is searching for a place to stay. By chance, he meets a beautiful woman who turns out to be the proprietress of a small nearby inn. Due to the rainy weather and lack of guests, she offers him a room for the night. The inn is run by her family, but her husband works in Tokyo during off-seasons and is currently away, while her son lives in a dormitory at school in Tokyo—leaving her to manage everything alone. Moved by her lonely struggle, the man becomes determined to have her. Back in his room, he asks her for a massage, but she refuses, saying services aren't available. Undeterred, he pleads, "I don't mind if you're bad at it—just please give me one." Hesitant, she finally agrees, muttering, "If you really don't mind me being bad..." During the massage, he starts teasing her, whispering, "No one will know if you don't tell," but she resists, saying, "This is wrong! Stop it!" and quickly leaves the room. Unsatisfied, the man sneaks into her bedroom while she sleeps and begins massaging her again. Unaware at first, she gradually wakes to find her thighs and crotch being touched, already too far gone to resist. Overwhelmed by pleasure, she begins to give in. Though she protests, "My husband will be angry..." she cannot fight the sensations, and soon starts responding to his advances.
