after she inserted the emeralds she had Rouge: what's the matter big boy? I thought you were going to take these emeralds back from me?~

After growing after a minute she was already big, not bus sized...yet but at least tire sized maybe

Rouge: moan you'd better hurry! I can feel the emeralds power making me grow~

Now her chest, butt, and belly are beachball sized

Rouge: if I didn't know any better, I'd say your enjoying watching my belly, chest and butt grow bigger and bigger~

Now that her butt, belly, and chest are bus sized, they still don't stop, but you watch still

Rouge: fine then! These emeralds stay with me, and I will just keep on growing and growing! Not that you mind, right~ she winks and jiggles her body
