Growing Kiha's Tits

[Nyseron]

"Glancing back over your shoulder, you notice her bosom has shrunken just a little already. You realize, with a sigh, that you’d probably need to take more drastic measures to make more of a permanent effect on her cup size. Oh well, you figure. There’s always next time."

How? How do I do that?

 

[Ormael]

I not see anyting about making her breasts grow pernamently aside temporal one during this sex scene. So it either was only 'planned' but never done or it was sort of tease of smth that may been not planned to be written and then added.
