A small village is depopulating and on the verge of disappearing. Faced with the reality that no children are being born, the villagers make the choice to recruit "collaborators" from the outside. The one chosen is Fumika, the young wife of a powerful man. She has never left the village and is truly naive. Having lived naturally within the village's values, her judgment of things is slightly skewed from the norm. A few days after the recruitment ad is posted, a young man visits the village. After the details of the job (having raw creampie sex with the wife to provide seed) are explained, Fumika mates with the man. Though confused at first, once she accepts his raw cock, emotions she has never tasted before begin to sprout. From that day on, she does everything she can to stimulate his sexual desire and encourage erections, begging for impregnation sex. While she initially faced the village's "way of doing things" with confusion but sincerity, before long, Fumika began spreading her legs for the sake of pleasure, transcending her role.
