After my father-in-law died, three months have passed since my mother-in-law and I lived together. Today, her mother-in-law suddenly said that she wanted to be an underwear model. It seems that he had applied without telling us, and his wife, who was informed of the fact after passing, took a firm stance of opposition and ended the discussion. I had a strong feeling of bewilderment, but that night I witnessed my mother-in-law's lingerie that I couldn't give up from the gap in the room. I was immediately fascinated by the expression and appearance of my mother-in-law, who I had never seen.
