JUL-211 Living dangerously sweet with my boss's woman. 'If you touch me, I'll be killed by my boss?' Nao Kamiya

I was living a dull life with no dreams or hopes when my older brother and his girlfriend, Nao, suddenly showed up at my place. The most violent man I know is him—my older brother. Even in my own home, they had sex without caring about my presence. One day, my older brother suddenly disappeared, and I started living alone with Nao. For the next five months, we went shopping together, did laundry and cleaned together... like lovers. I gradually became attracted to this woman whom I absolutely should not touch.
