Hiroyuki, a young man who was fired from his 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 cursed by my brother, saying, "I'm a pathetic man who is a virgin even at the age of 30." Hiroyuki, who wants to gain confidence at all costs, offers his lifelong wish to take his virginity from his brother-in-law, Ai. Ai, who sympathizes with Hiroyuki, forgives her body for a little, but she is attacked by a numbing pleasure "the moment she inserts it".
