Kaede and Odagiri worked at the same company and used to date each other, but he married the daughter of the partner's director, so Kaede broke up with him. Some time later, she and Tanizaki got to know each other and planned to get married. Right now, she was assigned to go on a business trip with Odagiri. Even though she didn't want to, because the project was very important to the company, she had to agree. After finishing the negotiations, while planning to return to Tokyo, the train was stopped due to a fire, so Kaede had to spend the night at the hotel. But when she arrived at the hotel, she realized there was only one room, and there was no other way, so she had to stay here. Taking this opportunity, Odagiri put an anesthetic in the water and gave it to Kaede to drink. Without any doubt, she immediately drank the water he gave her and quickly felt different. Her body was aroused, thirsty for love, her mind was empty and only wanted to be sexually satisfied all night long!
