Rarity doesn't often try new magic spells, but every so often one comes along that she has to give a shot. If only she didn't screw this one up so badly.

While flipping through her newest fashion magazine, Rarity comes across a spell that apparently allows to user to dress themselves instantly. Intrigued, she decides to give it a test and see if it works.

The results are interesting...

Don't Try Magic That You Learned From Tabloids

Rarity wasn't often one for sensationalism...

Oh who was she kidding, yes, she was. She strived to be sensational, in her personality, her work, sometimes even her day-to-day life. But the type of sensationalism found in tabloids—unbased gossip, attention seeking stories, and the like—it was the kind of sensationalism that made her want to turn her nose up in disgust.

But every so often she did find herself reclining on her couch, sipping iced tea, and flipping through the pages of The Canterlot Enquirer. Not for news or anything like that; articles found in these... less that reputable magazines were only good for one thing: comedy. Rarity so rarely allowed herself to indulge in such carefree pastimes, but this was one she made an exception for.

Rarity chuckled as she flipped through the pages. "Fleur de Lis having mane extensions." She shook her head. "What will they think of next?"

She took a sip of her tea and continued flipping through the pages, looking for any other good 'stories' that it had. Unfortunately, it didn't seem like many were left. All she could find after a few more flips was the same weekly-recycled story about Sapphire Shores using lip syncing and some bland trite about some other nobles.

Certain that the Enquirer had run its course for her already, Rarity was about to put it down. However, before she could, her eye caught something. A massive, colorful advertisement that dominated one of the pages and the words at the top: 'If you care about fashion, you have to try this.

No harm in looking, I suppose. Rarity's magic pried to pages fully open again and she scanned the page for further details.

If You Care About Fashion, You Have To Try This

A new experimental spell, fresh from the magicking world, has finally hit mainstream fashion. Any pony can tell you that putting clothes on is a hassle. Even unicorns still struggle, despite telekinesis. Well now there's a special spell that puts on an entire ensemble on you in an instant! Just follow the steps below!

Rarity nodded her head, lips pressed together. She could attest to the ad's claim about clothes being unwieldy. She'd often struggled to put on dresses, even with her experience and magic combined. There was just so much fabric to trip over and get tangled in that it was always a difficult chore. She had to admit that a spell to bypass that struggle would be welcome indeed.

Her curiosity piqued, Rarity's eyes wandered to the bottom of the page and looked over the instructions. It seemed they were all there, which was curious. She'd doubted somepony would have spent so much money on this ad just to give away the whole secret. It was... a little dubious to say the least.

At the same time, Rarity wasn't too worried about it. Surely The Enquirer wouldn't publish this advertisement if it wasn't legitimate. Besides, she was way to excited about the prospect of instant dressing that she was willing to try it. Who knew, if it worked she might be able to start wearing clothing more regularly.

She read over the steps again, just to make sure that she understood them well enough. The first step said that she needed to have her outfit of choice in front of her, so she rose from her couch and glanced around the interior of her shop. While dresses lined the racks all around her, she figured it was best not to try out her spell here. With so many clothes in eye view, she didn't want the spell to get confused. Giving it some thought, she remembered that she had a mannequin upstairs already set up with the first dress of her fall lineup. It would be the perfect test outfit for the spell.

Setting her ice tea off to the side, Rarity trotted over to the stairs, magazine in tow. As she ascended them, she flipped back through the pages to re-read the steps again. Once again, it all seemed very cut and dry, so her confidence that she could do the spell only rose, as well as her excitement.

Being able to casually wear clothes would be great. Not only could she show off her wares around town, but if this spell got out to more unicorns, than clothing in general could become commonplace around Ponyville and her business would boom! Just the thought made her giddy with anticipation.

Clearing the last step, she went over to her sewing room and opened the door. Waiting for her on the other side was the dress she'd been thinking of. Long and red, with orange accents and puffed sleeves.

She smiled. Perfect.

Dropping the magazine, she prepared to focus her magic solely on her body. Step two laid this part out in particular detail, so she hoped she got it right. Next, she made sure to get a good look at the outfit, drinking in all the details from it before moving onto the final step: casting the spell.

With a flash of blue light, Rarity cast the spell without a second thought.

And promptly blacked out.

She opened her eyelids slowly, groaning as a rush of light hit her eyes. Rarity brought up a forehoof to shield her face as she finished waking up. Her head was pounding with an achy sensation that stemmed from her horn.

"What happened?" she moaned, rolling to her side. It was then that she realized she was lying on the floor of her sewing room. Blinking against the light, who's harshness was fading, she glanced over to the clock on her wall. It read seven o'clock.

"Seven?" she gaped, incredulous. "But I could've sworn it was four..."

Suddenly, she snapped awake, the memories of before her blacking out coming back to her. "I've been unconscious for nearly three hours?" She grunted out a cry of fury.

That stupid spell! And I followed the directions so well! Rarity began to sit up, deciding to write The Canterlot Enquirer a very strongly worded letter when she was--

crinkle

Rarity paused, a soft sound hitting her ears. She blinked in confusion, looking around the room for what the source of the noise was. She didn't see anything, and began to sit up again.

crinkle

There it was again! Rarity stopped and looked around again. She hoped that whatever was making that noise would stop soon. She wanted to get off of the floor, even it if was really soft. Especially around her derrière.

...wait a minute.

Rarity glanced down with suspicion, then did a double-take. Wrapped around her waist was something fluffy, plastic, and poofy. She blinked with confusion, not sure what exactly it was for a moment, but then it became painfully clear.

She was, undeniably, wearing a diaper.

Rarity screamed.

"Sweet Celestia!" She bounded up, and glanced back at her diapered rump. The foalish garment pushed her legs apart slightly as she stood, making her feel awkward just by standing. With each movement of her hips, the plush padding would shift, pressing itself against her flanks and rear end.

Not wanting to let this thing impede her mobility, Rarity tried pressing her legs together to stand normally. Unfortunately for her, that caused a good chunk of the soft padding to dive right into her marehood. She twitched at the sudden, surprising feeling and blushed.

"H-How did this get on me?" she cried, slapping away the rising heat on her cheeks. She looked around, hoping to provide some clue as to what happened. Unfortunately, the only thing she saw was an empty mannequin. Emphasis on empty. "Where did my outfit go?" she asked aloud.

She took a curious step forward, as if her current angle was just somehow making the outfit invisible to her or something. All that accomplished though was to cause the padding between her legs to slide against her marehood, causing it to quiver. Rarity blush came back in full force; she was not liking what the diaper was doing to her. Just to prevent it from happening again, she reluctantly spread her legs a little further apart, letting the padding fall back to it's usual spot.

"This is absolutely bizarre. What in Equestria happened?" She glanced back from her diaper to the empty mannequin, before her eyes finally fell to the magazine that laid sprawled on the ground. "You!"

With her magic, Rarity scooped up the tabloid, hoping that it might have to key to understanding what had just happened. She practically ripped the pages with the speed she turned back to the ad and she furiously looked it over. Towards the bottom, she found a previously overlooked warning printed in a tiny font that did not do justice to the importance of the words.

Warning: The transfer process causes an enormous strain on one's magic, usually resulting in unconsciousness. Also during transfer, the outfit may spontaneously transmute into a random article of clothing. Most test subjects reported diapers as a common side effect, but bibs, bonnets, booties, pacifiers, and monocles have also been reported.

Rarity huffed. "Well that seems like something that really should've been mentioned at the beginning. I never would have tried this spell had I known this was a possibility!" She shuffled her hips to make a point to the magazine, but that only served to press the plush interior of her diaper against her intimate areas. Again.

Blushing heavily, Rarity's head snapped back to the diaper. "That's it, you're coming off right now!"

The fact that she hadn't removed it the instant she learned she was wearing it wasn't lost on her, but she attributed that to shock and confusion. Now, she was just angry. Apparently her newest creation had just been transformed into a diaper of all things, simply because she had been foolhardy enough to practice magic she learned from a tabloid.

"Never again," Rarity huffed as she gripped the diaper with her magic and pulled. The diaper responded by staying firmly put.

Nonplussed, Rarity yanked harder on it, but the diaper stayed affixed to her waist, shifting only slightly. Rarity couldn't stop yet another blush as the padding once again found its way onto her marehood. Worried, Rarity poured everything she could into her telekinesis and pulled as hard as she could. The diaper jerked upward, practically wedgie-ing her in the process. As the padding slid over her most delicate areas it tickled them gently and Rarity couldn't stop a moan of pleasure from escaping her lips.

She quickly cut off her magic and slammed a hoof over her mouth. For a moment, she stood wide-eyed, unable to believe what had just happened. When her senses came back to her, she quickly brushed the moment off.

"Why aren't you coming off?!" she huffed at the diaper. Her attention swiveled back over to the tabloid and she grabbed for it again. Looking over the page, she found another warning below the first, this one twice as disheartening.

Due to magical residue leftover from the transfer process, the clothes will be temporarily affixed to the body. Most cases only last half an hour at most, however victims of transformation have reported the clothes being stuck for at least twelve hours, if not longer.

Rarity dropped the tabloid in shock. "T-Twelve hours?!" It took a moment for what this meant to sink in. She was going to be spending the rest of the night stuck in a diaper, if not longer. Her chest tighten at the thought. "This can't be happening," she cried. "Of all the worst possible things that could happen, this is the. Worst. Possible. THING!"

She wanted to faint, but seeing as her couch was downstairs she held off on the idea. Just as well, the movement might cause the diaper she wore to... do that thing again.

"This truly is awful!" Rarity bemoaned to her empty sewing room. "Forget a strongly worded letter, I feel like marching to The Enquirer's office and giving my opinion to them in person... a-after I get this foalish garment off of me though."

Her stomach rumbled just then, and she realized that it was well passed the time she normally ate dinner. "I... I suppose that will have to come after I eat something."

It seemed, unfortunately, that the diaper was here to stay. The thought made her groan, but it could be much, much worse. This could've happened in a public place, after all. At least at home nopony was around to witness her humiliation. Sweetie Belle wouldn't be staying her until next week, and she didn't have any errands to run, so there was that to be grateful for.

But it didn't change the fact that she was wearing a diaper.

Her stomach growled, reminding her that it was still empty.

Rarity sighed, and started out the door to head to her kitchen. Unfortunately, as she tried to walk normally, she squished the padding of the diaper and it did... that thing again. Wiping away her blush, Rarity spread her legs apart slightly and tried again.

It was... better. The diaper only rubbed her a little bit now, but she didn't want it rubbing her at all. She spread her legs even further this time, hoping that it would work.

As she took a few steps, Rarity stumbled a bit. With her legs so far apart, walking normally would be difficult. She resigned herself to a foalish waddle instead and blushed with embarrassment. It wasn't ideal, but at least she wasn't blushing with... other things.

She climbed downstairs, taking great pains to have her diaper not agitate her on the way down, and crossed to her kitchen. Sparking her horn to life, Rarity began preparations for a simple meal. She decided on a salad, and threw herself in to making one.

The process of food preparation for her was an art. An art that required one hundred percent of her focus. She was grateful to find that this allowed her to push the thought of her foalish garment out of her mind for a time. Despite the occasional way her legs brushed against the plastic, it was almost like it wasn't there.

Rarity managed to hum a soft tune to herself as she grabbed some vegetables from her fridge and brought them over to the sink. She turned the faucet on and water was soon rushing out. She grabbed a head of lettuce and placed it underneath to wash it.

For a while, the menial task occupied her time. Between cleaning vegetables and humming, she was able to totally ignore the diaper.

Then she felt the urge to pee.

It was a small thing, ignorable mostly. Likely it was brought on from listening to the running water, but it still made Rarity pause. She quickly shut off the faucet and pushed the desire from her mind. If the diaper was stuck to her body, then that meant that she couldn't go to the bathroom, which was very, very bad.

Rarity knew that her nightly routine often involved taking a moment to relieve her bladder, but with this diaper on...

No, don't think about such a... horrid action.

She switched tasks, feeling confident that her future salad had had a good scrubbing. With her magic, she opened a nearby drawer a retrieved her cutting board and a knife, and began slicing up some carrots.

Halfway through the second one, Rarity toyed with the idea of using the knife to free herself from the diaper. Sure, it was stuck to her body, but surely it wasn't indestructible. A good slice from the knife and she'd be freed... right?

She shook her head. No, the diaper had been created from her dress, if she ever wanted to get it back, she'd have to leave the diaper in one piece. At the moment, she just wasn't desperate enough.

Over the next hour, she continued to work on her salad. The urge to urinate came back once more, but she still pushed the desire down. If it was just for the night, she was sure she could survive without using the bathroom.

The clock struck eight by the time her salad was finally finished.

"Ah, perfection." Rarity set it down on the kitchen table, placed a fork next to it, and lowered herself into her seat. However, she hadn't taken into account her diaper, and squeaked in surprise when she sat down and her rump sank deeply into the padding.

Her blush came back in full force and she squirmed to try and get to a more comfortable position. Needless to say, this only served to push her marehood against the padding, hardening her blush and cementing it's existence for the rest of her meal. Rarity could only sigh as she picked up her fork, stabbed her salad, and took her first bite.

While chewing, the constant rubbing of the padding with each movement caused her face to heat up even further. Now that she was forced to deal with this, she finally decided to think about what it could mean.

Why does this keep happening? I'm not... trying to like it, but the padding is so... soft. So... warm. So... a-arousing. That's it. It's practically designed to be arousing. She paused at that realization. Was she really aroused by her diaper?

Rarity swallowed her salad, fervently shaking her head. There was no way, right? Just because her diaper felt... good against her marehood, it didn't mean that she was taking a liking to it, or getting any lewd ideas from it.

"And I'll prove it, too." Rarity said firmly. "A-After all, as long as I don't enjoy it, that means I'm not aroused... right?" She looked at her hoof, an idea blooming. "Right, so if I... for example... did this." She pressed her hoof onto the crotch of her diaper. The padding pressed deeper onto her marehood and Rarity felt her breath shorten. "R-Right. See? I don't like it. If I liked it, would I do this?"

She started slowly rubbing her hoof against her diaper, grunting at the sudden waves of pleasure that washed over her. "R-Right. I don't like it, obviously. I could do this all night and not get an iota of enjoyment out of it." She rubbed harder. Faster "Unf! D-Definitely not enjoying it!"

Rarity brought her second hoof down, smacking the table in her eagerness and not caring. Now two hooves were working in tandem on her diaper, each pressing and rubbing against the crotch, slamming the padding against her marehood over and over. Rarity's breaths became ragged and she started sweating.

"OooOOooH!" She cried at the feeling. It was wonderful. It was bliss. It was...

...disgusting.

For a brief moment, she got a moment of clarity and realized what she was doing. Masturbating. Here, at the dinner table. In a diaper off all things.

Shame overtook Rarity. Her hooves shakily left her crotch, and fell to her side. The realization of not only what she'd been doing, but how much she'd been enjoying it really grabbed hold of her.

This shouldn't be happening. She was a lady of refined tastes; how could she stoop to that level? She'd never, ever found anything appealing in diapers before, and now this was happening.

She took the time to remain motionless and quiet. It was several minutes before her horn relit and she continued her meal. She barely moved, and completely refused to touch her diaper.

Once her meal was finished, she left the salad bowl in the sink and trudged upstairs. She didn't bother with brushing her teeth, or washing her face or anything. Right now, she just wanted to sleep. To kill time until her diaper would be able to be removed. To escape this nightmare.

She hurriedly flipped off her light and crawled under the covers, trying her hardest not to pay any attention to the crinkly garment hugging her rear. Despite wrapping herself up in blankets though, she still couldn't fall asleep. The earlier events were just too rattling.

"I... I know that was wrong," Rarity said into the darkness. "B-But I couldn't help but feel that it was so... right."

Everything was silent for a moment.

Rarity shifted to her side. "M-Maybe it's just part of the spell... making me feel things and think things that I definitely should not be."

She rolled onto her back again. "Or maybe I really do like... this."

She kicked her legs gently, listening to the soft crinkling of the diaper. It was wrapped so snuggly around her waist. So comforting.

Her hoof snaked down towards it before she even knew it was moving. It pressed against the padding and she shivered with delight.

"It couldn't possibly hurt to just... try it again. Just to be sure." At this point, Rarity knew she was making up excuses, but she didn't really care. Her hoof was already rubbing the diaper, and the sheer pleasure from earlier was back again.

"MMmmmMMmmm!" she murmured, smiling at the feeling. She rubbed harder, fully acknowledging what she was doing was deviant, but not caring. Tomorrow she could rip off the diaper and pretend this all never happened, but tonight would be dominated by lust.

She pushed harder, letting her marehood free from the diaper for just a moment before plunging it back into the sea of padding. Rarity moaned and sighed with delight, absolutely loving this feeling.

And then a new feeling came to her. The urge to pee was back again, stronger this time now that she'd committed to skipping her routine. Her rubbing slowed as she acknowledge the need to urinate, but instead of pushing it down she got an idea.

Dare I? She thought.

Too late, she was already peeing. It seemed her body knew what she wanted before even she did.

Rarity paused to let nature take it's course. Her warm urine flowed into the diaper and was greedily soaked up by the padding. She felt the diaper expand and when she went to press her hoof back against it, it squished.

Rarity squealed.

Her rubbing was twice as fast now, the warmth of her pee adding to the pleasure she was getting from her diaper. She knew this was dirty. Filthy even, but she didn't care. No matter what, she couldn't deny how much she loved it.

With her newly squishable diaper, Rarity didn't last much longer. Her orgasm erupted out of her and her whole body shook in what she would later describe as the most satisfying experience of her life.

When it finished, her hoof fell from her diaper. Her eyes were half-lidded and drooping, getting closer to being closed. Across her face she bore a dopey grin that would put Pinkie Pie's finest to shame. At this point, she didn't care that she'd probably just ruined her new dress, or had committed herself to a fetish as gross as using a diaper. Rarity was just happy.

And happy she would stay.
