Rieko and Takashi work for a hot spring inn consulting company. The two of us decided to go on a field survey of the renewed hot spring, but due to a mistake at the inn, only one room was available and we ended up staying in a shared room. The benefits of this inn's hot springs are nourishment tonic, fertility treatment, and libido enhancement. After taking a bath, Takashi gets lustful and attacks Rieko. Takashi's cock is unexpectedly too strong, and Rieko loses her reason and asks for another vaginal cum shot over and over again.
