The life of the Yukihira couple was very happy until one day the husband was suddenly transferred to a distant place for work, meaning he could only come home once a month and Yukihira would have to live in a state of severe emotional deprivation. Not long after being apart, a major incident occurred in the house. It was a fateful night, a thief sneaked into the house to search for valuable items, but the most valuable thing he saw was Yukihira - a girl sleeping with a plump body, which aroused desire inside the thief. He quickly tied her up and threatened her not to scream or he would punish her. Too scared, she could only lie still and let him do whatever he wanted. After that night of rape, Yukihira was haunted by the thief, fearful but also unable to deny the pleasure in the act because she had not had sexual relations for a long time. Not long after, he broke into Yukihira's house again, this time bringing two accomplices. They continued to approach her to commit perverse acts, but this time Yukihira did not resist but instead lay still enjoying the pleasure that the three strange men brought.
