It's been a year since I married my wife and started living with her mother, Yumi. While my wife insists we start having children, I find myself completely obsessed with the perfect charm of my stepmother Yumi. Even though I try my best to avoid looking, my eyes are always drawn to her. One day, I went to the bathroom and saw Yumi's discarded underwear in the laundry basket. Unable to resist the temptation, I reached out and grabbed them.
