During a family getaway to a hot spring resort with his in-laws and wife Yu Shinoda’s husband Daisuke is finally hoping to rekindle their spark. Despite Yu's apparent lack of interest in sex lately—and the parents' eagerness to meet their future grandchild—they agree that an intimate vacation is the perfect catalyst. However, Yu sets strict ground rules: Daisuke must abstain from intercourse for a full month *and* refrain from masturbating! As the deadline nears its end and Daisuke reaches peak arousal levels after returning to their room without immediate gratification,
he finds himself utterly frustrated when Yu initially refuses him. On the verge of giving up and heading to soak in the hot springs alone, Daisuke mistakenly enters the women's bathing area. Seeing Yu bathed and exposed before him sends him into a state of near delirium; he rushes towards her, desperate to claim her body! Though he manages to pull back from what feels like an impulsive mistake, later that evening, even when granted permission by his wife, his mind remains fixed on his stunning mother-in-law. He declines his wife and heads straight for Yu one more time.
Unable to control his desires any longer, Daisuke tackles the beautiful Yu in the privacy of the bathhouse, unleashing a torrent of accumulated semen deep inside her womb. Despite her initial resistance, Yu succumbs entirely to his hard, massive cock. She begins taking charge, matching his rhythm while secretly deceiving her husband and daughter so they can enjoy private moments with their son-in-law. Soon after this passionate encounter, much to everyone’s surprise—and confusion—Yu is found pregnant!
