Cream snapped out of her trance once she heard her mother's voice. "Oh, hey Mom." She sighed. "I'm okay. Just...thinking about some things..." She looked back at her figure in the mirror. It was obvious something was bothering her. But she didn't want her mother to worry for her. Cheese floated beside her, patting her shoulder.
Vanilla walked in and sat on the edge of her bed, looking at their reflections in the mirror with a worried expression. She folded her hands and looked up at her daughter, who had grown quite tall in a year's time. Not quite on her level yet, but almost. "And...what things would those be?"
"...It's just...my body." Cream sighed while rubbing her hands over her hips. "I was hoping I'd be much bigger by now. Bigger than you, even! But...it feels like my growth spurts have been slowing down lately."
Vanilla knew that's what the answer would be. After the years she spent trying to help Cream maximize her growth, she too had hoped that Cream would surpass her. And in some ways she did, in fact by the time she was 14, Cream's butt was already larger than hers. But her bosom hadn't quite reached that same level of extreme proportions.
Mind you, Cream was by no means small, she was close to reaching the size of bowling balls for her chest, which was far larger than an average female her age. But compared to her, and not to mention Amy, whose boobs had inflated to a point where she was somewhere in between her and Cream in size, she was still not very big up top in comparison. The vast majority of her growth had been focused on her butt, with each cheek at least as big as her head, if not close to being more.
Her boobs, unfortunately, had not kept up the pace. Cream was still undoubtedly growing quickly, but it was slowing down a bit. And the fact that Vanilla's boobs kept raising the bar that Cream had to reach didn't help matters. "Honey you're as big as I was 2 and a half years ago, that technically means you made it to my size!"
"I guess...but I want to be as big as you are NOW!" Cream said with her fists clenched. "In fact, I wanna be gigantic! Humongous! I want to be big enough to be visible from space!" She went on, clearly getting excited over the prospect of reaching such sizes, before deflating back down to her previous state of mind. "But I'm not sure how much more my body is capable of growing. If only there was some way I could just make my body grow as big as I want anytime I want."

Another year has passed, and Cream's growth is continuing...but she's not content, she wants more, she wants so much MORE! And she expresses these thoughts to her loving mother, who herself is still becoming bustier. You can read the full story HERE.
