I suspected as much, even if it could have been exclusive to Rosy. But then, it was just a suggestion based on the logic of the game. If that's not possible, I'm not going to ask for more.About the Rosy Potion
Such a potion probably wouldnt be added for 2 reasons; 1) it takes away the fun of knocking her up so she makes milk, 2) If he adds a milk producing (potentially tit growing) potion then using it on 1 girl feels like a waste of a potion & people would beg for other girls to get the same treatment (be comparable with the potion). This si because they have been asking for a potion or spell to change tit size for a long time & it's been denied based soley on how much work would have to go I to changing EVERY scene to have smaller & larger versions of the girls....
Rosy is already fine the way she is ^^
