Living together with my wife and her mother. From one day on, I couldn't take my eyes off my mother-in-law. Her sensual figure, glistening with sweat yet craving pleasure, deeply stirred my heart. One night, when my wife tried to initiate sex, I turned her down, claiming exhaustion. My mother-in-law overheard the conversation, and I ended up confessing that I couldn't get her out of my mind. That moment marked the beginning of unbearable tension and desire.
