[Chinese]ROYD-020 During the five days my parents were away on a trip, my sister who had just gotten engaged kept inseminating me until she got pregnant. Shinogawa Aina

From way back, the younger brother had been having sex with his sister repeatedly. If he could stay in this relationship forever... But finally, he faced the reality he had always feared—his sister's marriage. Up until now, they had avoided pregnancy by using contraception, but that was no longer necessary. And during the five days spent alone with his sister, they craved each other more intensely than ever before, drowning in sex. The sister said she would pass off any resulting pregnancy as her husband's child and for the first time received her brother's semen inside her. The more they had sex, the more inseparable their hearts and bodies became.
