My younger sister Emi and I have feelings that are more special than just a brother-sister relationship. One day, while we were living together and supporting each other, we suddenly received a notice from the government. It was a letter of forced marriage due to the "Childbirth Promotion Act"... My precious Emi was forced to become a married couple with a greasy middle-aged man, and her developing body was played with and creampied over and over again! ...But before I knew it, she had fallen for his skilled techniques, and she was shaking her hips and begging for a creampie from the man she should have hated!! I... my beloved sister was cuckolded...
