Female Student Inseki Sister Oppai Younger Sister

His father's remarriage was suddenly announced without any consultation. As a result, "Kosuke" is suddenly sent to live with his sister-in-law.

The two sisters are very close and have opposite personalities.

One is the bright and mature Kana, who calls herself "big sister" even though she is younger than Kosuke. The other is the reclusive Sayo, who hates men and only shows her grumpy face to Kosuke.

After only a month of living together, her father moves into a new house with his new wife. As a result, Kosuke is left to take care of the two sisters. Fortunately, the two sisters seem to get along well, so Kosuke decides to just take care of the money sent to him and do the housework. He decides to live peacefully.

Then, a few weeks after the three of us were living together, one morning... I wake up in the same bed with one of my sisters-in-law, Kana...
