It's been a while since my mother-in-law and I have been living together with our family of three. We've been getting along well, but today, my mother-in-law suddenly expressed her desire to become a lingerie model. It seems she had secretly applied for it without telling my wife and me. My wife is firmly against the idea, feeling embarrassed about her mother posing in lingerie. I was bewildered, unable to fully understand the situation, but that night, I accidentally witnessed my mother-in-law's lingerie-clad figure through a gap in the room. Instantly, my gaze was captivated by her beautiful lingerie.
