It's summer vacation, but you're messing around doing absolutely nothing. Suddenly, your grandmother calls and asks you to help manage the student dormitory as a replacement manager.
You agree to this and go to the hostel. Upon arrival, you unexpectedly ran into a childhood friend, kohai from your part-time job, kohai from your former school club and your separated little sister. To top it all off, all these girls are younger than you !!!!
Not only that, but they seem to be asking you (in various ways) and are gradually getting closer to you.
Whether they are childhood friends, or your sister. Sex life with these young girls is just beginning !!!
