An intimate encounter between a mature married woman and a young physical therapist during a private stay at a hot spring inn. Eleven years into a childless marriage, Namidae (fake name) is exhausted by her dissatisfaction with her husband and seeks new excitement through travel. The relationship with the man she initially accepted for her husband's sake gradually deepens as they passionately indulge their desires. She welcomes kisses from this stranger, passionately sucks his erect cock with her long tongue, and opens her mouth wide as she repeatedly reaches climax with his rock-hard erection thrust deep inside her. For a woman whose marital sex life had dwindled to just a few times a month, this trip becomes the beginning of a new world of pleasure.
