“Yuta, could you abstain for the month before our trip?” My parents-in-law's sudden request left me confused. What was supposed to be a family hot-spring getaway had become a plan for me and my wife to conceive. I abstained until the trip as requested, only for my wife to turn me down. Unable to contain the desire that had built up, I headed for the baths to cool off but accidentally entered the women's side. There, I caught sight of my mother-in-law's alluring naked body in the water.
