Kaede and Odagiri work at the same company and once dated each other, but he ended up marrying the daughter of the director from a partner company, so Kaede broke up with him. Some time later, she started dating Tanizaki and was considering marriage. Just then, she was assigned to work with Odagiri, and although she didn't want to, she had to agree because the project was very important for the company. After finishing the negotiations and intending to return to Tokyo, the train was stopped due to a fire, and Kaede had to stay overnight at a hotel. However, when she arrived at the hotel, she found out that there was only one room available, and with no other choice, she decided to stay. Taking this opportunity, Odagiri put some drugs into a drink and gave it to Kaede. Without a hint of suspicion, she drank the beverage he provided and quickly felt something unusual. Her body was tingling and craving intimacy, her mind was blank and all she wanted was to be sexually satisfied throughout the night!
