You decide to add size to her boobs as well as give her more.
First you wished that she had 4 rows of 2 boobs that were all rr size, you also wish that these new additions would not hinder her in any way but that she that they just randomly grew and she does not not know why.
While you watch here closely for any sign of a reaction, you quickly wish, that when she was a secret nudist and that she always took her clothes off when she came home.
As what you said in the wish, she started taking her clothes off once she got in the house, it was when she got down to bra and pantie level, she noticed that three rows of nipples and areolas below her boobs coupled with small bumps underneath everyone on them, rather shocked, she quickly unhooked her bra and slid off her panties as the bumps and her original breasts grew bigger and bigger, before all eight of her breasts reached absolutely epic proportions and looked ridiculously heavy, if you didn't have a boner beforehand, you did now.
After about a minute of standing in shock, she smiled, presumably trying to think how this happened while massaging the boobs, you look rather surprised but you decide to do more.
