Saori, my brother's wife, is a 42-year-old attractive woman. Always carrying herself with grace, she's popular among everyone around her. I've long seen how much my brother adores her, and drawn to her beauty, I always hoped to grow closer to her someday. One day, I suddenly visited my brother's house and caught Saori masturbating in her room. She looked slightly embarrassed, but her allure remained unchanged. That moment struck me with overwhelming intensity.
