"Would you like to abstain for one month before the trip?" It was supposed to be a hot spring trip without family water, but I was asked to take advantage of it and have a child with my wife. As a result of abstinence until the day of the trip as I was told, my body ached so much that my erection did not subside, and I headed to the hot spring to calm my desires ... I accidentally entered the women's bath, and by chance I witnessed my mother-in-law's glossy bathing appearance.
