My mother-in-law Maiko suddenly arrived at our home after arguing with her husband and leaving because she wanted to become a lingerie model. I was confused, my wife objected, and Maiko refused to back down, so we agreed to let her stay for a week. The next day, after my wife left for work, Maiko approached me while I worked from home and asked me to photograph her in lingerie with a smartphone. When she slipped into the revealing outfit, I could only stare and swallow hard.
