My brother is an embarrassing bron

The Misaki family, where her mother passed away two years ago, lived in her father, daughter and son. My father works hard for his family, and his older sister looks at his father's back, and his daughter goes to school and does his housework instead of his mother. However, the older sister has secretly held her feelings more than her younger brother to the younger brother from old days, and it has spent the day killing and masturbating such a thought. However, one day when the father was gone on business trip, he went out of the way to his brother!
