Found on a dating site: my brother's wife Yuna Ishikawa

Six months ago, my younger brother got married and started living with us in our family home. His wife is cheerful and diligently doing her best as a housewife. However, there was one problem—her underwear kept appearing among the laundry. Every time I found it, I would jerk off picturing her in my mind. Then one day, I discovered her secret... The shock completely shook me to the core.
