> POV
The girl herself, past tense

> Starts day one of growth?
Nah, i'd say this starts a day or two before if we want to get technical

>How fast?
Pretty fast at the start? I think? She goes from a flat chested or a B-cupm to J by the end of the school year then jumps from J to O during the summer.
> What struggles?
Growing pains, stretch marks, the constant hunger fueled by her body demanding resources to turn into more glandular and adipose tissue on her breasts. Not to mention outgrowing bras and clothes constantly paired with her disposition for her breasts to grow longer rather than in all directions. There's also the fact that she's a twig outside of her boobs. When her doctor tells her she needs to stop drinking onions milk (and other phytoestrogen rich foods) she has the rough dietary changes to handle too.
> How does the rest of the school react?
She retains one or two friends who don't get envious of her growth. Teachers always give her shit, and rumor goes around that her boobs are so big because she lets everyone massage them. Beyond that I don't know
>Any other fetishes you want to add?
Lactation, obviously, Possibly that it runs in the family when a younger or older sibling starts having the same thing happen.
> Final size?
As far as breast-to-body ratio goes picrel is probably my ideal stopping point, probably when her body decides it's done, or the growth slows down to a reasonable level.
> How would you end the story?
I adore corruption so the idea of a lesbian character warping her to enjoy the growth and what comes with it super nice. Plus, I just like when the person growing enjoys it. She goes all in on consuming the worst things for her condition, once her mind hooks onto the idea of growth being hot, and discovers she somewhat of a masochist. If being turned on by growth making your boobs hurt, or getting off at the idea of being pinned down by her own boob. She eventually comes a vtuber or streamer or something. idk
