Living in my older brother's house due to work circumstances, I rarely see him because our schedules don't match. However, his wife, Chinatsu, is always kind to me, making each day exciting and thrilling. Ever since my brother first introduced me to Chinatsu, I've secretly fantasized about having such a wonderful wife of my own. One day, my work plans changed and I returned home early, only to discover Chinatsu watching a porn video and masturbating alone. I tried quietly leaving, but she noticed me. Rushing back to my room in panic, Chinatsu soon followed and asked, "You saw, didn't you?" I nervously nodded. "You must despise me," she said, but I shook my head. In that moment, I finally confessed, "Actually, I've always had feelings for you, Chinatsu." Then she whispered, "Will you keep what you saw just now a secret?" I agreed without hesitation. "Then, in exchange for keeping it secret..." she gently closed her eyes and slowly brought her lips toward mine.
