"Shinichi-kun, please, can you abstain for a month until the trip?" my father-in-law suddenly asked, and I was confused. It was supposed to be a hot spring trip without family water, but I took advantage of it and was asked to make a child with my wife. However, my wife is not interested in making children and refuses no matter how many times I invite her. When I was wandering around the inn in the middle of the night to calm the desire that had accumulated in the pool after abstinence, I happened to witness my mother-in-law's glossy bathing appearance.
