To eat as much cake as she wants and send it to her ass.

Peach loved cake. She loved it. The soft, spongy texture, the creamy frosting, all the sweet add-ons like fruits and candies. It was most of the reason she liked baking them so much. But cake was incredibly sugary, and she had to watch her figure. She only baked them when she planned on sharing. She didn't want to get fat. She had her pretty looks to maintain, after all.

At least, she didn't want to get fat in most areas. But there was one particular part of her body she wouldn't mind getting bigger. True to her name in some sense, Peach loved butts. She had to watch herself when hanging out with her female friends, lest they caught her staring at that part of their anatomy. She believed the bigger, the better, and hers was no exception. While it wasn't small, it wasn't big, either. It was round and tight, and while some girls would be happy with an ass like that, Peach wanted more. She wanted a big, jiggly butt that wobbled with every step. She wanted a real shelf behind her.

And now, she had a solution to both problems. She could turn her cake into cake. "Hmmm~, I wish I could eat all the cake I wanted without getting full, and that all the cake I ate only made my butt bigger and fatter!" The wand glowed, but Peach didn't feel any different. Then again, there really wasn't any reason why she should feel different, but still, she would have expected there to be something.

Now was time to test her little wish. She looked to her counter at a cake she had completed earlier, covered in white frosting and sweet little strawberries. She had planned to give it to the Toads staffing her castle, as a thank you treat. They'd live without it, though. It was time to dig in.

She grabbed a knife and cut a perfect slice out of it. Replacing the wand in her hand with a fork, she took a bite, giving a delighted "mmmm" as she chewed. It was heavenly, as always. Years of practice had perfected her cake-crafting skills, and when she didn't accidentally leave them in the oven too long, her goods always came out amazingly delicious. The cake was perfectly moist, and the frosting melted on her tongue. It wasn't long until her plate had been completely cleaned. She ate another slice, then another. Eventually she gave up bothering to slice it and just ate off the whole cake. She was in pure bliss. It was rare for her to indulge her sweet tooth like this.

Where there once was an entire cake, now there was nothing but crumbs and little piles of frosting. Peach licked her pink lips and rubbed her belly. Downing a whole cake in one go was an impressive feat for her, and yet she didn't feel the least bit full. She could go for another. Looking over the pieces of her current cake in progress, she picked up the want and stated, "I wish my second cake was already complete and decorated." The separated layers faded from their pans, and next to the remains of the first cake appeared a chocolate cake, three layers high, completely covered in rich frosting, decorated with even more chocolate pieces and flakes. It looked just how she had intended to make it.

She began chowing down on this second cake, savoring each chocolatey bite. As she worked through it, she noticed her dress felt funny around her rear, like it was suddenly. She looked back at her butt, mouth still full and deep brown crumbs decorating her lips. Her skirt was, in fact, looking tight. Swallowing, she reached a dainty hand down and gave one cheek a squeeze. Sure enough, it was a bit larger than it used to be. She smiled and squealed in joy. Her wish was working! She gave her hips a little wiggle, and her ass, in turn, gave a little jiggle.

Peach could almost jump for joy. She returned to eating the cake with greater speed and vigor. The rest of it disappeared in no time, and Peach stumbled back into a chair, sighing in content. While she still wasn't any fuller than before, there was still a satisfaction to eating a whole chocolate cake. She expectantly looked down at her ass, but frowned in confusion. It wasn't any bigger than when she had last checked it. She stood up, lifting both cheeks with her hands to make sure. Nope, not even a little more heft.

Peach was about to get mad, when she felt a slight rumbling in her butt. Then she saw it, her ass cheeks pushing out bit by bit as her panties tightened and her dress rose. And it stopped. It seemed like it took some time for what she ate to make it to her ass.

She slapped her ass, watching it recoil a little from the ****. It was a start, but not much of one. Her butt was more cushion-y than when she started her day, but it still wasn't what she'd call big. It looked like she'd need to eat a lot of cake if she wanted to make any significant progress on it.
