This is Gunma’s “Child-Treasure Miracle Hot Spring.” The story of three couples who visited this famous spring. Right beside the husband who has fallen asleep, the therapist gives an ultimate massage hitting the pressure point closest to the uterus. The more they endure, the more the wives writhe and burn! A lewd closed-room drama of wives twisting to endure the swell of pleasure, husbands sleeping while their beloved wives are taken, and a therapist who precisely attacks a woman’s weak spots with his whole body.
