FPRE-034 Deceive the rebellious big-breasted little sister whose body has grown into an adult! Taking advantage of her lack of sexual knowledge, punish her with pleasure control! ～Nonoe Mitsuha～

Due to my parents' remarriage, I, a college student, gained a stepsister. She's Mitsuha from the J-system, in her rebellious phase and seems to despise me. She's insolent and infuriating, but physically she has firm, large breasts and is very feminine. However, this sister often shows panties or exposes too much skin, seemingly lacking sexual knowledge... Using my age and cunning, I plan to deceive Mitsuha and control her pleasure to make her my SEX doll! 'Damn brother, can we really do this?' 'Mitsuha, sex is amazing!'
