Yoshie's tutor, Ibuki

There was one thing to look forward to when I was married and moved from the company house to help my older brother and wife carry their cargo. It was to live under one roof with a beautiful woman and a big breasted sister-in-law, Kaoru. Then, in the words of my brother and sister-in-law, I learned to study. She was the first woman to enter my room, even though she was my sister-in-law, and I couldn't help but clamoring for a private class with only two people. My brother-in-law, who reacts honestly to both my mind and body, has a motherhood and jealousy.
