過疎化が進み、消滅寸前の小さな村。子どもが生まれない現実に直面した村民は、外部から‘協力者’を募るという選択をとる。選ばれたのは権力者の若い嫁・ふみか。彼女は村を出たことがなく、本当の世間知らず。村の価値観の中で自然に生きてきたため、物事の判断基準が一般とは少しズレていた。募集広告を出して数日、一人の若い男が村を訪ねる。仕事の詳細（嫁に生中出しセックスをして子種を与える）を説明して、ふみかはその男とまぐわう。最初は戸惑いながらも、生の肉棒を受け入れると今まで味わったことのない感情が芽生える。その日から彼の性欲を掻き立てるためにありとあらゆることで勃起を促し、孕ませ性交を懇願する。最初は村の‘やり方’に戸惑いつつも真面目に向き合っていたが、いつしか役割を超えて快感のために股を開くふみかだった。

A small village, on the verge of extinction due to depopulation, faces the reality of a lack of ********. The villagers decide to recruit an 'assistant' from the outside. The chosen one is Fumika, the young wife of a powerful man. She has never left the village and is truly naive about the outside world. Having lived naturally within the village's values, her standards of judgment are slightly different from those of the general public. A few days after the recruitment advertisement is posted, a young man visits the village. After explaining the details of the job (to have unprotected sex with the wife and give her his seed), Fumika has sex with him. At first, she is hesitant, but once she accepts his raw penis, feelings she has never experienced before begin to sprout within her. From that day on, she does everything she can to stimulate his libido, and begs him to have sex with her to get her pregnant. At first, she is confused by the village's 'way of doing things' but tries to deal with it seriously, but before long, Fumika opens her legs for pleasure, going beyond her role.
