Yousei Shidou ~Lolita Shoujo no Choukyou Jugyou~

The girls, who start out crying and hating everything you do -- but soon the pain and resistance turns into pleasure and joy...

When the change occurs, thus begins the next part of the training...

And the ending as you reach the end of the training? You'll just have to play and see...

How it goes is all up to the player (main character)!
