Rieko and Takashi work for a hot spring house consulting company. The two of us decided to survey the new hot spring field, but due to the confusion at the inn, there was only one empty room and we eventually had to live in the same room. The benefit of this hot spring is nutritious, treating fertility and enhancing libido. After bathing, Takashi got lustful and attacked Rieko. Takashi's dick was so unexpectedly strong, and Rieko lost his mind and asked for another sperm shot to another vagina from time to time.
