The woman my brother brought home when he got married was a calm and kind-looking lady. I fell for her at first sight. Since then, over the course of more than ten years, I have harbored secret feelings for my sister-in-law Mutsumi. A turning point came for me a few months ago. Due to work circumstances, I ended up staying at my brother's house. My brother's children had already left the nest, and my brother and his wife welcomed me into their home gladly. When I returned home after a night shift, I heard Mutsumi's troubled breathing. She was alone, comforting herself. Seeing Mutsumi in her embarrassing state, I panicked and apologized before rushing back to my room. Later, Mutsumi came to my room looking embarrassed. As she tried to speak, I interrupted her and confessed that I had liked her for a long time. After a long silence while we looked into each other's eyes, Mutsumi took my hand and nodded. We naturally embraced, kissed, and entwined our bodies...
