The latest installment of the popular series features exclusive star Meguri, portraying the daily life of a childless married couple. Under pressure from her father-in-law and stressed by work, her husband has developed a habit of frequent smoking. Taking advantage of the husband's smoking breaks, the father-in-law suddenly steps in under the guise of helping with fertility efforts—launching straight into quick, no-foreplay creampie sessions. Those five minutes when the husband steps out for a smoke become the father-in-law's creampie time! A total of ten creampie loads are delivered in rapid succession, all aimed at ensuring pregnancy. Unaware at first, the wife gradually gets drawn into the father-in-law's repeated creampie encounters.
