Shinjin 22-sai no Onee-chan Ura Mono AV Debut!! Saitou Hanako

Saito Hanako is a talented fourth-year university student and the pride of her family. Her younger brother harbors secret lustful feelings toward her. When Hanako becomes trapped in a debt crisis—her ex-boyfriend scammed her out of 5 million yen—the siblings consider an unconventional solution: making an amateur adult film to repay the debt. Unable to film with his sister directly, the protagonist recruits Kaneda, an otaku friend, as the male lead. What unfolds is a story of financial desperation, family taboo, and unexpected passion as the characters navigate the production.
