I'm a Woman Now, But I'll Always Be Your Little Slut (Kaori Ojima Debut)

Milky was looking forward to coming home from college and seeing how much his stepsister Kaori had grown. However, when they see each other again, he realizes that the little girl he once met is now a slutty young woman. Entitled and forward with him, Milky decides that Kaori needs a harsh wake-up call. The issue is that, no matter how mean he is to her, Kaori only gets hornier and hornier. Drawn to his discipline, she practically begs him to treat her like a bad girl, getting her pussy wet every time he even frowns at her. Finally, he understands that the only way to talk some sense into her is to fucking her hard like the slut she has become.
