My daily life living with my mother-in-law and wife took a sudden turn one day, shaking my heart to its core. It all began when I accidentally caught sight of my mother-in-law secretly seeking pleasure on her own. From that moment, she became someone special to me. One night, when my wife finally sought intimacy after a long time, I turned her down, claiming exhaustion. My mother-in-law overheard our conversation, and I honestly confessed my feelings to her. Lowering her gaze, she whispered, "Just tonight, just once," and gently pulled me by the hand toward the bedroom.
