Kaede and Odagiri work for the same company and used to date each other, but he married the director's daughter on his partner's side, so Kaede broke up with him. Some time later, she and Tanizaki got to know each other and planned to get married. At this moment, she was assigned to work with Odagiri, although she didn't want to, but because the project was very important to the company, she had to agree. After the end of the negotiations, he was about to return to Tokyo when the train was stopped due to a fire, and Kaede had to spend the night at the hotel. But when she arrived at the hotel, she knew that there was only one room, and there was no other way, so she had to stay here. Taking this opportunity, Odagiri put the anesthesia into the water and gave it to Kaede to drink. Without the slightest doubt, she immediately drank the water he gave her and quickly felt strange. Her body was burning, her thirst for love, her mind was blank and she just wanted sexual satisfaction all night!
