Yuichi, a young man who was fired from his company and kicked out of his house, ends up staying with his brother and his wife until he can find a new job. However, he doesn't have a place in his brother's house, and every day he receives insults from his brother, saying, ``You're a pathetic man who's still a virgin even at 30 years old.'' Wanting to gain more confidence, Yuichi makes his lifelong wish to his brother's wife, Yuki, to take her virginity. Yuki sympathizes with Yuichi and forgives him for just a little bit, but ``the moment he inserts it,'' he is attacked by a numbing pleasure.
