ADN-382 — Dear Wife, I Might Have Impregnated My Unrelated Sister... Hikari Ninomiya

Ten years ago, my parents remarried and Hikari and I became siblings. Although we weren't related by b**, I never saw her as a member of the opposite sex, probably because of the age difference. However, in the two years we hadn't seen each other, my step-sister Hikari had grown up a lot. Now, I see her as a woman.
