Questioning her married life, she contemplates infidelity, having separated emotionally from her childhood friend husband, now seeking a new relationship. Pressured by their parents to conceive, sex with her husband became joyless, leading to two years of no intimacy. She steps into an affair. Though her tension seemed to ease during the journey, a kiss at the inn makes her stiffen again. Her beautiful, troubled expression turns passionate as her genitals are licked, her breath quickening, desire igniting. As the cock thrusts inside, she moans softly, her slender body writhing with pleasure. At dinner, she actively approaches him, successfully capturing his attention. Aroused, he pounds into her at high speed, her body twisting in ecstasy. The next morning, she initiates a kiss, seduces him again, and enjoys new sex with him in an outdoor hot spring.
