Twilight could only whimper as she was teased about needing a change by every maid that passed her on the way back to her room. Sadly once twilight was back in her room she was lifted and set in a large foal bouncer rather than on the changing table. “What?! No you stupid book, change me! Ewww gross, I don’t want to bounce in this mess!”

To Twilights dismay she had no choice as the rope started pulling and bouncing her in her seat causing her to squish on her full diapered rump. The book simply sat there on the table, while twilight squirmed in the bouncing seat. For 20 long minute’s twilight try anything except magic to get out, sadly the bouncer was set in a way only a feat of pure strength would allow her to climb the moving ropes and get out. A feat which twilight was not strong enough to do. Once she finally gave up, and just sat there waiting for the book to decide when it was time to change her. The book decided then to come over and open the front page where normally there was a blank page there where words.

“Want a diaper change little foal?”

Twilight blushed and nodded. “It can communicate? Is some kind of witch or dark mage trapped in the book?”

The words changed on the page. “Feed me.”

Twilight immediately shook her head no glaring at the book.

“Then no lunch and no change until after nap time in 40 minutes.”

Twilight blushed she was already feeling some itching on her rear. Her pride wouldn’t allow it though as she shook her head no again. The book simply went back to the table, and twilight was left to the bouncers mercy. Ten minutes later twilight was regretting her choice as the itching was getting unbearable and she was tired of feeling her but kneed the mess in her diaper. When she started to cry, the book came back.

“Want a diaper change little foal?”

Twilight nodded again though she noted the books repetition which would indicate this was written in the books spell rather than some form of a soul or being trap in the book.

“If there’s no soul fused with it then it probably just feeds on a pony to store magic. There are four pretty quality garnets on the spine. That would hold a huge amount of magic even with how complex this tome must be I doubt it really needs that much magic to run. That’s it it’s a dark magic milking tome its designed to keep a pony trapped while it milks them for their magic for the witch or dark mage to use. But there’s no huge storage for it to deposit the magic if I can fill it full beyond its capacity maybe I can overload the book allowing me to cast freely and escape.”

The book had just been sitting there with the words feed me while twilight was thinking. She grinned and gave the book what it wanted and poured all her regular magic pool into the book and it just took it. She gave it all she had till she was sweating and panting and her body felt nub like when she over practice her magic and couldn’t move. The book just closed up lifted her out of the bouncer and took her to the changing table.

“Guess it wasn’t enough. No matter I just need to outpace the tomes use of magic I can feed it more once I eat and sleep.” Twilight mused while the book undressed her and a strap held her down on the table. Magic floated a lot of wipes over as it started to clean her messy bottom. Twilight shiver each time a new wipe got to work. It was pleasant to feel the itching go away but the wipes where ice cold. Once the wipes finished cleaning her, the used diaper was balled up and dropped into a trash can. A new diaper was laid under twilight’s rear, powder was added, then taped up nice and snug. Twilight was unstrapped from the table carried over to the high chair and set in it. A moment later twilight was being fed some red and white mush that she could only guess from the taste was cherries and peaches. After the mush she was lifted out of the chair and bundled up like she was for bed before, and fed another bottle of cream, though she noticed it wasn’t as sweet.

“Great, that’s why I’ve messed a ton it’s been feeding me laxative in the bottles.” Twilight just groaned as she was set in the bassinet, the mobile wound up, and she was left to finish her bottle before napping.

Back with Princess Celestia and Princess Cadence

Princess Celestia and Princess Cadence where sitting on the bed and watching twilight though the crystal ball spy glass.

“Don’t you think this is a little cruel aunty maybe we can just end it here.” Cadence looked and sounded like she wasn’t having fun anymore.

“I understand you're concern Cadence I really do. This lesson, however cruel would end up losing most, if not all its impact if I let it end here. I’ve learned that one’s lessons must feel like they have a proper conclusion for the lesson to be learned.” Celestia spoke giving a thousand yard star at the crystal ball. While she seemed to enjoy teasing Twilight during the outing, Cadence could see she didn’t enjoy the whole lesson. After Twilight had been laid down for her nap Cadence held out her hoof to Celestia and Celestia clapped her hoof against it. “Tag your in.”

After Twilights nap

Twilight awoke to the feeling of being held against a warm body as she was rocked. As her eyes cleared the grogginess away she saw Cadence looking down at her with a smile.

“Cadence oh thanks you now I can get out of this mess.”

“Awwww there my wittle filly did you enjoy your nap?” Cadence said in a tone you’d use for a foal.

“What? Cadence no you’re an alicorn, your magic should be strong enough to let you see though the perception spell. Unless… I boosted it when I fed the tom, Celestia dame it all!” Twilight squirmed in the bundle as she wished she could just bang her head against a wall.

“Uh oh is someone needing a change after her nap?” Cadence said as she patted Twilight's diaper though the blanket. “hmmm no, oh I know!” Cadence then rested the blushing twilight against her shoulder and started to pat Twilight's back. After a couple of pats twilight let out a small burp nothing that was really bothering twilight, but the fact she was just burped made twilight blush more.

“Ugh! If more blood rushes to my head from sheer embarrassment I swear my head is going to pop. What do I do now? If I keep trying max out the tome Cadence won’t be able to see though the perception spell, but I can’t be sure it will drain fast enough for Cadence to see though it while she’s here.” Twilight contemplated her choices while Cadence unbundled Twilight and set her on the changing table as she dressed Twilight in some pink hoof mittens and a bonnet.

“Aww who’s a cute filly.” Cadence mused as she then blew raspberries on Twilights tummy causing her to giggles and squeal. Once Cadence stop and Twilight still didn’t look happy Cadence carried her over to a blanket and set her down. “Twilight let see if I can teach you my favorite Hoof shake hmm.” Twilights looked at Cadence as she bent down. Twilight knew full well what Cadence wanted she had already taught her this and at the same time she couldn’t help herself as she mirrored Cadence.

“Sunshine sunshine ladybugs awake clap your hoofs and do a little shake.” Cadence sang as Twilight copied though her word were lisped thanks to the pacifier, although judging from the smile Twilight now had, she didn’t care even as she shook her diaper but at Cadence.

“Even when she’s treating me like a foal she knows how to cheer me up. Ok there’s no point in back tracking now if I’m going to max the book out, this just means I’ve got to push a little more, and I think I can take this if Cadence is taking care of me.” With her mind made up she looked for the tome in the room. It was sitting right on the table like before Twilight grabbed it with levitation and once she felt the book grab hold she dumped all she had into the book. She was now back to feeling exhausted, though as she sat down with her magic pool empty she noticed something different. Her diaper felt thicker and her pacifier now seemed to fill her mouth completely.

Cadence simply giggled. "Oh my, did you want me to read you a story Twilight I think I can find something better than some big old tome."

Twilight just sat there her nose scrunched up as she thought. "It’s unloading some of the magic into my clothing it must already be getting close to full if it has to do that. Good one or two more times and I should be free to cast magic and escape.”

Twilight was lifted by Cadences magic as she was then set in the pink princesses lap and a childish looking picture book was held in front of her while Cadence hugged Twilight. Twilight for once didn’t mind she still blushed but only because she remembered doing this back when she was young enough that it was normal, though then she wasn’t in diapers. Twilight look down at the book and read the title.

To Stop a Cute-Ceañera

“That’s odd why would anyone want to stop a cute-ceañera and why would that be a children picture book?” Twilight thought as Cadence opened the book.

“Look Twilight this little filly just got her cutie mark.” Cadence said as she showed Twilight the first page. There was a little white filly that looked like Twilight back when she did her yes dance. Cadence then turned the page.

“It seems the filly’s parents are planning the filly’s Cute-Ceañera.” The next page showed the parents looking at party supplies. But the next picture showed the same parents informing the filly of the new chores and responsibility’s the filly would have when she grew up. After Cadence explained the next page to twilight she flipped the page.

“Oh my, it seems the little filly didn’t like the idea of having more work and now doesn’t think growing up is all that cool anymore.” Cadence giggled as the next pic showed the filly trying to wash off her cute mark. Then trying to paint over it, and finally resorting to staple a piece of paper over it, with comedic effect. Cadence turned the page once more.

“Look Twilight it seems the filly found some diapers and other foal stuff.” Cadence giggled more as these pages showed the filly finding everything, getting an idea, putting on the diapers, foal attire, and then getting happy as the diapers covered her cutie mark. “Seems the little filly thinks she can stop growing up by acting like you Twilight.”

This comment made twilight blush again which grew to her whole head as she suddenly felt herself trickling into her own diaper without control. “What!! No stop I didn’t want to…why… the book it had to of done something, used the extra magic to make me incontinent or something, I didn’t even feels the need to go… I hope it’s not permanent.” At the pace she felt herself wetting she take ten maybe fifth teen minutes to finish peeing.

“Oh look Twilight seem she’s really serious about not growing up she’s using the diaper.” Cadence said pulling Twilight's attention away from her predicament as she saw the pages. The filly was holding a rattle now and the pictures showed her diaper getting slightly more yellow. The final picture was the parents finding the filly in the soggy diaper.

Cadence turned the page once more showing the parents talking with the filly about her cute-ceañera, but this time the filly was asking them to stop it. The next picture was the parents trying to tell her to still go through with it, that she’d love growing up. “It seems the filly’s rather stubborn Twily.” Cadence said as the last picture was the filly stomping her hoof and demanding no cute-ceañera and the parent just face hoofing.

Twilight finally relaxed as her body finished soaking her diaper at the slow pace. Cadence turned the page showing the parent laying the filly down to change her diaper and trying once more to convince her to let the party happen. They bartered with the filly saying that it won’t be a cute-ceañera just a party for her and her friends. This got the filly to agree saying how she could warn them of growing up and too go back to diapers.

Twilight suddenly felt a hoof peek its way into her diaper leg cuff. “Seems like the filly in the story is not the only soggy one.” Cadences picked Twilight up and carried her over to the changing table. Twilight on the other hoof while it was a children’s picture book still wanted to know what would happen. The one thing she hated was stopping in the middle of a book, especially stopping on a cliffhanger.

“Come now twilight you need a change and its din din time.” Cadence said as she strapped the squirming Twilight to the changing table. Twilight stopped and whimpered as she got changed into a fresh diaper.

“Oh don’t cry Twilight I’ll finish reading you the book when I come back tomorrow OK. I’ve busy princess things to do so I need to let the maid feed you and put you to bed.” Cadence set Twilight in her high chair and buckled her in then started for the door.

“NOOOOO!!! Finish it finish it, if you leave you’ll forget about this and possibly never finish reading it to me!!!!!!!” Sadly Twilight couldn’t say any of that from the big binky in her mouth and could only slump down as Cadence left. For the first time she cried like a foal as the book made up her mushy dinner.

Back in Princess Celestia room

“Are you honestly sure that was necessary. You know Twilight loves books, and even for a silly foalish book it broke my heart seeing her break down from being left on a cliff hanger like that.” Cadence said the moment she closed the door from returning.

“Yes my niece, it’s all part of my conclusion.” Celestia sipped from her tea as she floated a second cup to Cadence.

“And which part is that?” Cadence took a seat on the bed.

“The healing part.”
