We're a shy couple working at a factory. On my girlfriend's 19th birthday, I bought a cake and we had a quiet overnight date at home. When I finally undressed her, I discovered her slender beautiful body was that of a dirty sex monster... Kanna Amane
My relationship with my quiet and kind coworker at the factory grew deeper each day, and we both secretly harbored feelings for each other. One day, she confessed to me, and we began dating. Both of us are homebodies who share a love for games and manga—an introverted couple through and through. Today is her 19th birthday. Since neither of us enjoys big events, we decided to keep things simple: buying ingredients and a cake from the supermarket to celebrate quietly at home. In this peaceful setting, our warm feelings for each other will shine, making it a truly special day.
