In the village of Ruri Kyonyu, where depopulation is advancing due to low birth rates, a campaign to revitalize the village through internal fertilization activities was initiated. Four single girls with G-cup breasts or larger in the village, known for their large breasts, engage in impregnation sex to welcome prospective grooms! The village maidens, all boasting G-cup breasts or larger, serve their ample bosoms, exciting the men to the peak! The maidens' wombs are filled repeatedly until the men's sperm is exhausted! Will this ensure the village's lineage?
