ADN-382 Dear wife, I might have gotten my sister by blood relation pregnant… Hikari Ninomiya.

Film Introduction

Ten years ago, my parents remarried, and I became siblings with Hikari. Even though we're not blood-related, due to the age difference, I had never seen her as a woman. However, after two years of not seeing each other, my stepsister Hikari has become quite refined. Now, I can't help but see her as a woman.
