My younger sister Eimi and I have a more special relationship than just a brother-sister relationship. One day, while the two were living together and supporting each other, they suddenly received an announcement from the government. It is a strong marriage letter based on the ``Act on Promoting Childbirth.'' Precious Eimi is forced to become a couple with a greasy middle-aged man, and her developing body is played with and he is creampied! ...But before she knew it, she became an expert and started shaking her hips on her own.
