-18XX AD. During the war, the Mara Empire was suffering from a serious shortage of personnel. Therefore, the government implemented a policy of forcefully impregnating young women. Under such circumstances, I finally received a warrant. The target is his younger sister Haruka. She is a kind and gentle sister who takes care of me when I am sick. The younger sister, who has no choice but to comply with the government's orders, begins interbreeding with her siblings under the supervision of military personnel. Haruka moves as instructed. The instructions given by military personnel trained in mating guidance are accurate and of the highest quality so that more capable sperm can be produced. Unknowingly, I ended up cumming with my younger sister.
