One day, my mother-in-law suddenly came to Tokyo to our home, where my wife and I live. It seems she was scouted as a lingerie model and left her hometown to take on the challenge. My wife and I decided to let her stay with us for just one week to give her some time to cool off. That night, as I was heading to the bathroom, I heard a noise coming from the room where my mother-in-law was. Curious, I peeked into the room and saw my mother-in-law, still attached to her past, wearing lingerie. I couldn't take my eyes off my mother-in-law's enchanting expression and her lingerie-clad figure, which I normally wouldn't see.
