When this LUST bar is full, you will level up and gain ability points. Ability points are used to buy new lockers, leveling up will make the tentacles increasingly bold and fierce. To a certain extent, when the tentacles are strong enough to do bold things, you will see everything happening inside the drawer.
When you first started messing around at school, there was only one drawer where tentacles were present. But after collecting ability points, you will be able to buy new lockers. When you possess all the lockers in the school, play with all the girls, you will become the Tentacle King.
