Hitozuma Koukan Nikki 1

Kouichi feels trapped in his dull marriage to Kanako until his neighbor Kimihiko proposes a thrilling solution: swapping wives. At first hesitant, Kouichi soon surrenders to the forbidden passion of seducing Kimihiko’s willing wife while secretly lusting for his own. As the deception deepens, both couples indulge in raw, heated encounters—moans muffled, bodies entwined—rediscovering desire through stolen pleasure and the tantalizing rush of infidelity.
