An old inn in a town he visited on a business trip. It was an inn where the custom of "night companions," which had developed the town during the Showa era, still remains. A boss has his nipples and glans licked dry by the busty mature proprietress. Meanwhile, a subordinate has his glans relentlessly licked by the proprietress with beautiful breasts and a beautiful figure, and is fucked hard. As the subordinate falls asleep, the two proprietresses burst in to rape him, licking him dry before thrusting him hard and cumming inside him! And the story has a shocking ending!
