One day, my mother-in-law suddenly came to Tokyo while I was living with my wife. - Apparently, she was scouted to become an underwear model and wanted to take on the challenge, so she ran away from her parents' home. - My wife and I decided to let my mother-in-law stay at our house for a week to cool off. - That night, on my way to the bathroom, I heard a noise coming from my mother-in-law's room. - Thinking something, I looked into the room and saw my mother-in-law wearing lingerie. - I couldn't take my eyes off my mother-in-law's bewitching expression and her underwear, which I don't normally see.
