Karen has just graduated and joined a company. This time she went on a business trip with the department head Takeda, a very polite and kind person. However, the Shinkansen train encountered a power system failure, so Karen and the department head had to rent a hotel and stay there. Unable to go home, the business partner kept pouring alcohol for Karen, making her sleepy and having to be taken to the hotel by Takeda. Her boyfriend was very worried and called her, but the person who answered the phone was Takeda, which made him even more anxious. When they arrived at the hotel, Takeda did not leave, and Karen found out that there was only one room left, so she had to share the room with him tonight. Knowing that something was not right, before she could do anything, the department head forced himself on her, ejaculating all his semen into her. After finishing, he did not stop but continued to have sex with her over and over again. The pleasure of being fucked raw, reaching orgasm continuously, being touched in places that her boyfriend could never reach made Karen gradually forget everything. She only thought about Takeda's cock, wanting him to satisfy her sexual craving. That night, they continuously had sex, Takeda ejaculated into her eight times, but Karen still felt unsatisfied...
