My first love is my stepsister "Mizuki." Innocent yet highly intelligent, she carries a certain sensual charm. From the moment we met, she completely captured my heart. One day, she was humiliated and lost her virginity. Seeing my sister crying in the dim evening light, my heart ached. I held her tightly in my arms, comforting her, feeling her soft, warm body against mine. In that moment, I resolved to act on the feelings I had long kept hidden. Special bonus footage is included in both the DVD and Blu-ray editions.
