I appreciate the Hypnosis reference, but it's a shame that we can't use hypnosis to grow the girl who actually wants to get bigger.
I am sure Nunu is tired of me posting the same video time after time, so I will just include a link to a post about Alex and what it would look like if she kept expanding hers boobs. https://itch.io/post/11764570 if you see the video, you will see why we can't keep growing her boobs.
Well *clears throat* as Nunu would put it
If you want a more practical answer, then as cool as this function might seem to you, it would be difficult for Nunu to pull it off. Every increase to Alex's boobs would mean a lot of new images. With each increase a new design would need to be made for her model, and each size means a brand new set of images. Her images are at 224 at the moment and each BE is another 224 images. It even would reach the point of just being an image of boobs on her scenes and nothing else, if she is talking to someone you wouldn't be able to see them. Every scene she has that is supposed to make the player feel a certain emotion would be ruined due to the fact that all you see is boobs and not who they are attached to.
