"Ono-san, can you go without having sex for a month before our trip?" Suddenly, my father-in-law asked me. It was supposed to be a family vacation at an onsen resort, but he wanted to use it as an excuse to have sex with his wife. As requested, I abstained until the day of the trip, but I couldn't help feeling restless... When I finally arrived at the hot spring, I accidentally entered the women's bath and saw my mother-in-law's alluring naked figure soaking in the water.
