There was one thing I was looking forward to in the examinee, Noboru, who was helping my older brother and his wife who moved from the company housing after getting married. It was to be able to live under one roof with a beautiful and busty sister-in-law. And with a word from his older brother, Noboru was taught to study by his sister-in-law. Even though she was my sister-in-law, she was the first woman to enter the room, and I couldn't help but feel my heart pounding when I went up to a private lesson with just the two of us. In such a brother-in-law who reacts obediently in such a mind and body, motherhood and a mischievous heart sprout.
