"Ken-kun, can you abstain for a month before 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 even if I invite her. When I went to the hot spring to calm the desire that had accumulated in the pool after abstinence, I accidentally entered the women's bath and happened to witness my mother-in-law's bathing appearance.
