Married for five years and with no children... Hibiki is a married woman who works part-time at a factory in the city. On her way home from work, she is called out to by Hajime, a young man who also works part-time at the same factory. "Thank you for your hard work, Otsuki-san." There is a delicate atmosphere between this man and woman, who seem to be on friendly terms, yet somehow seem aloof and shy away from the public eye. A married woman and a university student. A record of an affair in which Hibiki's "desperate uterus" that cannot be satisfied by her kind husband is penetrated by his impressive young man's huge penis...
