Returning home to my parents' house during the Obon holiday, where my older brother and his wife were living together, I was greeted warmly by my sister-in-law. Seeing me after so long, she seemed genuinely happy, immediately striking up a conversation. "This room doesn't have air conditioning, so it must be so hot," she said, bringing me drinks and gently wiping the sweat from my body. Her kindness, however, stemmed from a growing desire for her young brother-in-law after so long apart. With nothing to do in the rural countryside, my sister-in-law found herself with too much free time, staying up late into the night. Eventually, she whispered seductively, "Would I... not be okay?" pressing her damp body against mine as she initiated something forbidden. Overwhelmed by her warmth and sweetness, my heart began to race.
