On this business trip, Riri had to go with the person she hated the most, the head of the department, Kita. He still has a bad reputation, specializing in sexual harassment of female employees, and of course he will not spare a beautiful person like Riri. When he arrived at the hostel, he found that there was only one room. The manager said that this was the company's opinion, Riri wanted to call to check but now no one answered the phone. She also couldn't find another place, so she had to endure sharing a room with him. While Riri was taking a shower, the head of the department put anesthesia into her alcohol and repeatedly forced her to drink. And while Riri was fast asleep, he invaded her perfect body. When she woke up, being threatened by the head of the department to tell everyone, including her boyfriend, about tonight's incident made Riri have to listen to him. And all that night, he fucked her countless times. Riri was given the peak of pleasure by the head of the department's cock for one night. She herself couldn't believe it. Although she was restrained, her pussy felt crazy every time the big cock of the head of the department clicked deep into the uterus. And by sunrise, sexual pleasure had spread throughout Riri's body. The next morning, when the train had not yet departed, the head of the department wanted to fuck her again. And this time Riri was more proactive, she wanted to enjoy the pleasure of being fucked by the head of the department. He fucked her while calling her boyfriend. She also made a decision, when she returned, she would talk to her boyfriend about the future of the two. As for the head of the department, she wants to be fucked by him more, even after returning to Tokyo...
