This summer vacation, I ended up staying at my wife's parents' house. Her family home is an old-fashioned Japanese-style house, exuding a nostalgic atmosphere. Welcoming my wife, who was happy to return home after a long time, was my mother-in-law, Kaname. She mentioned she had just been cooling off with a quick rinse due to the heat, her hair still damp. Seeing her like that stirred uncontrollable desire within me. Earlier, I had accidentally caught sight of my mother-in-law bathing, and couldn't help but stare intently at her alluring body. That image deeply moved me, and my excitement continued to grow.
