Shaken in the hot spring, shaken in love, a married woman's heart and body. The whole person goes on a hot spring trip together──Due to pressure from parents, she had been diligently having sex for procreation, but they both stopped enjoying it, and for the past two years, there has been none. A married woman who had doubts about marrying her childhood friend husband embarks on an affair journey. Midway through the trip, the married woman thought her tension had eased, but when kissed at the inn, she stiffened with tension again. Even as her beautiful body is fondled, the married woman looks troubled, but when her genitals are licked, her breathing grows ragged. When penetrated, she lets out restrained moans and writhes her slender body. From consultations during dinner, the married woman practices being proactive towards her husband by making the first move. Once the man is in the mood, he thrusts rapidly, causing her to writhe. The next morning, the married woman also kisses the man to seduce him, having sex in the open-air hot spring.
