[Chinese]MIAA-057 If it's found out that you were a bitch before marriage, wouldn't the engagement be called off? I threatened my reluctant sister and made her cum with incestuous rape! Sumire Kurokawa

Although bullied by my beautiful but former delinquent and strong-willed sister, I, her brother, have always harbored sexual excitement. She seems to be getting married, but I know about my sister's past as a slutty delinquent who engaged in perverted play. I'll use this information to blackmail her and force myself on her! I've been secretly filming and peeping at her sex with men, researching how to make my sister feel intense orgasms. It's time to show the results…! I'm going to give her a taste of her own medicine!
