On the day she left for a trip, I suddenly got a call from Aoi, a junior who had dumped me a long time ago, and visited the dormitory where she lived.Of course, no boys are allowed, but Aoi's friend, Ichika, seduces me because it's summer vacation and the dormitory mother and dormitory students are absent.Aoi, who had heard the voice of the love affair, also approached me.We asked each other like monkeys for three days until she came home.
