ぱいんハウス ～おにいちゃん教えて!～

There is a dorm called "Pine House," filled with dropouts who need to be straightened out before they return to regular academic activities. Unlike previous years, the dorm is now filled with lots of cute girls! 

You are hired as a tutor for the students at Pine House. The girls start to call you "Bro" as you become close to them. Not only that, it seems they really like you a lot! Will you be able to hold out on these flirtatious babes?
This is an ADV+SIM game, in which you'll have to discipline girls who have taken wrong turns. First, you'll try to talk with them and make good impressions. Once they start calling you "Bro," take their virginity away and train them to become your sex slaves!
