I ended up staying at my brother's house for about a week, and due to work circumstances, I spent a lot of time alone with my sister-in-law, Manami. She appeared gentle and had a calm, kind personality—seeming like the perfect woman. However, she had an unexpected side: an obscure fetish of always being naked when no one else was around. Witnessing her like that, I became completely entranced, gradually drawn into her daily life. It was as if she could only express herself through that naked form. Captivated by her allure, those brief seven days brought about a profound change within me.
