Returning home after a long absence, my spouse and I were worried about my mother, who had been depressed since my father's passing. However, the mother we met again was full of energy, and we had a wonderful time together that day. That night, I suddenly woke up and accidentally saw my mother bathing. Her alluring figure deeply stirred my emotions, leaving me unable to sleep. The next day, while shopping, I realized I had forgotten something and returned home—only to discover our familiar sake shop owner passionately kissing my mother as they indulged in a heated encounter. I stood frozen, unable to speak, my groin stiffening as I tightly clenched it.
