Kaede, along with the department head and a few colleagues, went to Nagano to negotiate business with a partner. They stayed at a hot spring inn nearby. Kaede is a new employee of the company, she is energetic, hardworking, and very beautiful. While resting in the room, Kaede texted the department head and wanted to have a drink with him. The department head agreed, and from then on he discovered the true nature of Kaede, a very lustful person, always wanting to extract every last drop of sperm from men. And the days spent here were the most tiring but also the most enjoyable days for the lucky department head, as Kaede always went to his room and demanded sexual satisfaction from him until the business trip ended.
