Three months had passed since my wife's mother began living with us following her husband's death. One day, she suddenly announced she wanted to become a lingerie model. It turned out she had secretly applied without telling my wife, and when my wife found out she’d been accepted, she fiercely opposed it and refused to discuss it further. Confused and unsure how to react, I remained paralyzed. That night, my stepmother revealed herself in lingerie through a crack in the door, and I was completely captivated. Her expression and demeanor were unlike anything I'd ever seen in her before, and I found myself breathless with desire.
