Yuta, a young man who was fired from the company and kicked out of his house, was allowed to stay at his brother's and his wife's house until he found a new job. However, there is no place for me in my brother's and his wife's house, and every day I am taunted by my brother, saying, "It's a pathetic man who is a virgin even at the age of 30." Yuta, who wants to gain confidence, offered his lifelong wish to take his virginity to his brother-in-law, Kana. - Kana, who sympathizes with Yuta, forgives her body for a little, but she is attacked by a numbing pleasure "the moment she inserts it".
