Rieko and Takashi work for a hot spring inn consulting company. The two of us decided to go on a field survey of the new hot spring, but due to a mistake at the inn, there was only one room available and we ended up having to share a room. The benefits of the hot springs in this inn are nourishment, fertility treatment, and sexual desire enhancement. After bathing, Takashi became lustful and attacked Rieko. Takashi's cock is surprisingly strong, and Rieko loses her mind and demands another vaginal cum shot over and over again.
