Twilight's diaper change.

After a magical mishap involving Princess Twilight Sparkle, Princess Celestia decides to see how she is doing. While listening to Twilight explaining the issues regarding her recent problems Celestia soon realizes she needs her help elsewhere. A diaper change ensues.

This is a commission written by TheVClaw aka Troius Clawston on Sofurry.


Celestia couldn't help biting her lip in uncertainty while standing outside Twilight Sparkle's door, despite the vast level of experience she had under her belt from her near-immortal lifespan. It's been less than a month since the... incident that involved her former student-turned Princess; but judging by the irritated groans the Alicorn could overhear through the door, it seemed that Twilight was just as upset about the results now as she was when it first occurred. And within that short amount of time, it seemed that all the time spent trying to console her among her friends was almost fruitless. But alas, even with Spike and Starlight Glimmer out of the castle (per Celestia's request), the Princess was determined to talk with her protegè as she knocked gently on the door.

"EEP!!" Even in her frustrated mindset, it seemed that Twilight hadn't realized anypony was outside her bedroom when she jolted in response. "W-Who is it?!"

"It's me, Twilight," answered Celestia in an audible, but still kind tone of voice. "I sent Spike and Starlight off to Canterlot for the weekend, and I... I figured you and I could talk privately."

Meanwhile inside of the messy bedroom, Twilight could only wrinkle her muzzle while standing beside the door in apprehension. Due to her isolation and depression, her once immaculate bedroom was as cluttered and disheveled as Rarity's workshop. Spike was usually the one to assist her in cleaning, but the young Princess was adamant about him and Starlight keeping their distances after that event a month ago. Of course, despite being grateful Celestia had them leave the castle for the weekend, Twilight hoped that the two weren't blaming themselves for her own predicament.

"Did... Did Spike write to you about me?" she asked timidly as she leaned beside the wall by the door, and used her hoof to rub her foreleg awkwardly.

"Well... yes, he did," answered Celestia in a more truthful-sounding tone. "He and Starlight were worried about how you were reacting to those support groups, so I... I figured a more personal conversation might suit you better."

Twilight sighed with her eyes tightly closed in annoyance, not wanting to even think about those "support groups." While she didn't want to offend Celestia in the slightest about her reactions to them (especially since the Princess arranged them herself), Twilight was sure her former mentor could overhear her frustrated grimace through the door. Nevertheless, her own anxieties weren't taxing enough to make her overlook Celestia's other statement. And despite feeling hesitant, Twilight would've been lying if she said she wouldn't appreciate a personal talk with her.

But alas, the weary Alicorn still felt compelled to ask in paranoia, "Is... is it just you outside, Princess?"

"Yes, it's only me," Celestia said warmly from the other side of the door. "You know I would never lie to you, Twilight. I just want to talk, so can you please open the door?"

After a brief bout of silence, Twilight sighed before floating out her robe. "Alright, fine," she said with an almost defeated-sounding tone of voice. "Just lemme do some things..."

With her horn brightly lit, Twilight was able to rearrange her bedroom into a more presentable state for Celestia. The bed may have been unmade, and a few books may have been left on the floor, but that was fairly standard for Twilight on a good day. Unfortunately, the Alicorn's magic proved to be fruitless when it came to trying to cover herself with her bathrobe. Despite how long the thick felt ran across her back, there didn't seem to be enough material to hide the thick, poofy padding that was tightly strapped around her waist and rump. Nor was that robe able to hide the distinct yellow tint the white garment carried while slightly sagging between Twilight's legs.

Regardless, Twilight knew better than to try and remove it on her own as she waddled to the doorway. After the multiple mishaps she had in the first couple weeks since that magic mishap, the Princess was willing to face the slight embarrassment of being seen in a wet diaper as opposed to another puddle on the floor. And while she had gotten fairly good at changing them herself, she didn't want to risk being caught in an awkward position if Celestia were to walk in halfway during. So even with the uncomfortable squishes she could feel with each step in her soggy padding, Twilight took a reassuring breath before opening the door.

"Ummmm... H-Hey, Celestia," uttered Twilight meekly as she poked her head through the open doorway with a small blush. She tried to keep the rest of her body hidden behind the door for obvious reasons while struggling to give a weak smile. "I... I'm not exactly looking my best right now."

"If I were to be frank, Twilight," replied Celestia with a coy shrug and a comforting smile, "I'm fairly certain I've seen you in more discomforting circumstances before this."

Twilight's muzzle pursed shut as she looked away with an embarrassed scowl, despite knowing that the Princess wasn't technically wrong. But before she could try and retort, the younger Alicorn yelped in surprise as she felt Celestia's magic wrap around her and open the door fully. Her soaked diaper may have been seen in full-view, but it seemed that Celestia paid no heed to it while hugging her tightly. "It's alright, Twilight. You can hug me back."

Despite her surprise, it didn't take long for Twilight to take her up on that offer. Of course, that may have been because of how often she had kept herself isolated in regards to her condition. And considering how accepting Celestia was being towards her, she felt a lot better being around somepony who wasn't taking notice of her diaper with uncomfortable stares or... other looks. So with all of her feelings finally having the chance to expel, it wasn't too surprising that Twilight's hug with Celestia lasted almost a full minute.

By the time the two Princesses pulled away, the padded Alicorn had to cover her muzzle with a hoof and sniffle a couple times. Fortunately, Celestia had enough life-experience to keep from bringing any attention towards that. Instead, she just walked over to Twilight's bed, while her horn remained lit to close the bedroom door behind them. After sitting down on the unmade mattress, Celestia patted the empty space beside her with a hoof to motion her protegè. "Come on, Twilight. Let's talk."

Seeing the warm and courteous smile on her face, Twilight felt compelled to go towards the bed with a smile of her own. Even when each waddling step caused that squishy padding to press against her nethers, Twilight was able to hide her embarrassment from Celestia. Although, the younger Princess still shivered uneasily when she sat down on her mattress, which made her wet diaper crinkle and squish audibly. But once again, Celestia didn't even bat an eye as she asked, "So... can you tell me what happened at your support group meeting?"

Even with such a kind mentor by her side, Twilight still huffed bitterly at that reminder. "Ugh..." She shook her head faintly while looking away from Celestia with disdain. "It was just... I dunno..."

"Well, I don't know either," replied the Princess rather bluntly behind her cheeky smile. "That's why I came by, after all."

Twilight closed her eyes and tried to sigh sharply and calm her nerves. "Sorry, I know I should explain," she replied apologetically. "I know you pulled a lot of strings to get me into that Incontinence Group, and I really do appreciate that."

"Well, given how that failed age-reduction spell affected your body, I didn't want to leave you feeling embarrassed or alone." Celestia knew there were a lot of things she could've said to her former student in regards to trying a spell that risky without supervision. However, given how badly it de-aged the Alicorn's sensory nerves to leave her incontinent, and possibly permanently at that, she knew that Twilight was dealing with enough grief to add any more of her own. So instead, she merely exhaled before adding, "Plus, I figured those ponies would appreciate seeing a Princess in a similar predicament."

"I know that," Twilight said while giving Celestia a courteous look of understanding, "and believe me, that is a noble thing to try. But it just..." Despite not wanting Celestia to feel her efforts were wasted, Twilight huffed and looked away again. "As I was hearing all of them asking what happened to me, and then hearing all of their stories in response, it just... it felt so disingenuous."

Celestia's brows rose in surprise at hearing that. "Disingenuous? What do you mean?"

"I just mean, like..." Twilight seemed to ignore her wet diaper as she hopped off the bed, and began to pace around the room while Celestia sat and watched. Even with each crinkly, squishy waddle she made, Twilight began to rant just as she did before her incident. "All of them were talking about their stories about being incontinent, and how they've gotten diaper changes in weird places, and it just... it felt like they were showing off or something! Or like... bragging about things that didn't even happen!"

"Oh, Twilight!" Celestia involuntarily scoffed as she got off the bed. "You really can't be assuming such things!"

"I know I shouldn't but YOU weren't there!" After pointing at Celestia insistently with that remark, Twilight went back to her pacing while ranting in frustration. "I mean, with the way some of those ponies were acting, it... it almost felt like they weren't really incontinent! Like, maybe they were, but the way they were talking about their stories made it seem like they were exaggerating for... for pleasure or something! It was... It was almost like they saw wearing diapers in public as somefetish or something! And don't try to tell me it isn't, because I did enough research to know it is!"

"Trust me Twilight, I probably know of more fetishes than you," replied Celestia with an honest sigh. "But... do you really think ponies would make up stories like that for your sake?"

"Are you kidding?! I swear, a couple of them were staring at me like I was on a centerfold or something!" Upon recalling the stare one pegasus was giving her, Twilight shuddered with a strong grimace. "Ugh! I... I know you had the best intentions, but... but that group just felt wrong to me! Like... Like they were trying to one-up each other with fake stories and insane claims for attention, or... or sexual gratitude! It was just really weird and uncomfortable."

Even though she wasn't sure how to process such a bold assumption from her former student, Celestia could tell from her frustration that she wasn't making up how she felt. So after taking a pained breath, the Alicorn walked up to Twilight to make her stop pacing around the bedroom. Without hesitation, the Princess hugged her tightly once more while her chin rested atop Twilight's head. "Oh, Twilight... I'm so sorry that happened. All I wanted to do was help you feel more accepted, and I... I wish I--"

"I-It's okay, Celestia," assured Twilight as she hugged her back, even though her voice almost sounded strained a couple times due to her emotions still feeling raw. "You didn't do anything wrong, I just... I think I need to find my own way. But... But, ummmm..."

Even though she blushed a little, Twilight kept a more timid smile on her face as she said within Celestia's embrace, "I... I can at least say I don't feel too lonely right now. Heh heh heh--NNNGHH!!"

Halfway through her attempt to be friendly with the fellow Princess, Twilight gasped the instant she felt a very familiar sensation churning in her stomach. Her heart began to race, and her face winced in utter dread. Since she was being held by Celestia, all that Twilight could do was breathe rapidly and struggle not to lose control. Despite knowing how fruitless it'd be, the Alicorn tried to desperately clench her bowels as tightly as her eyes. "Ohno... noooooo, nonononono...."

Celestia's eyes widened while hugging her protegè, not needing to be near-immortal to know what may have been the cause for Twilight's reaction. Of all the of the changes she had to endure since her mishap, Twilight's lack of bowel control was hooves-down the most notable and unpleasant. However, Celestia also knew that it was something her former student had no way of counteracting aside from her diapers. So instead of growing any worried expression, the Princess sighed calmly and kept her hold onto the incontinent mare. "Twilight, it's okay... If you need to go, I won't judge you, alright? I know it's something you need to--"

"N-NO!!" Twilight winced even harder as her hind-legs tensed up, and her breaths turned shaky and strained. She didn't want to interrupt Celestia so rudely, but her fear of being in such an awkward moment prompted her to try and speak between groans, "I... I--Nnnnghhhh... I... I think I can... hhhhhhhold it..."

Unfortunately, the Princess could feel her tail preemptively lifting up out of instinct, knowing what was bound to occur. Of course, it seemed that Celestia knew the same as she said firmly, "Twilight, we both know you can hurt yourself if you try to hold it in. Do you remember the last time you tried?"

Twilight grunted with her bottom lip tightly bit, not wanting to be reminded of that painful night of gastrointestinal distress. But despite how numb her bowels felt, and hearing that distinct crackling muffled by her diaper, she tried to speak up in defense. "I... IthinkIcandoit..."

"Twilight, I don't want you to try doing that," stated the older Alicorn in a stern and authoritative tone. "Now, I don't want to make that a Royal Order, but I'm not afraid to do so if you don't stop trying to hold it in. Do you understand?"

Even though she could hear the seriousness in her mentor's voice clear as day, Twilight could only groan in a mix of dread and overwhelming embarrassment. She wasn't even pushing, but she could already feel that all-too-familiar loosening within her diaper as something warm began to seep within it. The feeling was never pleasant, and the fact that Celestia was holding her while she did so made that feel even worse. She wanted to cry, or just teleport out of the room to soil herself in solitude; however, Twilight was able to remain within Celestia's grasp while hearing her say, "Ssssshhhhh... I promise you it's alright. If you need to go, then just go..."

The very last thing Twilight wanted to do was mess her diaper again, even though she had done so quite regularly for the past month. However, most of those times were while she was alone, and never while being hugged by someone so close to her. But as she stood in her sagging diaper, the feel of Celestia's warm and comforting embrace soon began to override the feeling of her mess dribbling down her covered rear. Just as she clenched her eyes shut with a pained wince, Twilight felt the weakened dams break when her mentor whispered assuredly into her ear, "It's alright, Twilight... Just let go..."

"Nnnnnnnghhhh!" Like the flip of a switch, Celestia's comforting words and tight hug were just enough to make Twilight relax and give in. As she let out a weak and shaky breath, the Princess' entire body shuddered as she felt her bowels working on their own accord. Even when muffled under that thick material, the familiar sounds of gas and excrement being released were heard clear as day among Twilight's shameful whimpers. Her already dirtied diaper quickly began to sag even more, as a strong torrent of her filth expelled out of her to fill that thick and absorbent padding. Underneath her raised and twitching tail, a faint hue of brown started to fade in among the white and yellowed plastic, which also bulged out lumpily.

The embarrassing ordeal only lasted a moment or so, but it felt long enough to make Twilight press her face in tightly against Celestia's neck and struggle not to cry. Meanwhile, Celestia kept a kindly content smile while petting her protegè's back tenderly. "Therrrrrrre we go," she whispered in a loving and supportive tone of voice. "I told you it was going to be okay. That wasn't so bad, was it?~"

"Mmmngh..." Twilight couldn't say much, but her wrinkled muzzle made it clear she wasn't comfortable with having done such a crude thing before Royalty. However, despite her apprehensions, the younger Princess still huffed hesitantly before muttering, "I... I guess not..."

"Alright then," said Celestia with a prideful smile as she pulled Twilight's head from her chest. After lighting her horn to lock the bedroom door, the mentor floated out the diaper-changing kit Twilight kept by her bed for convenience. "If it's not too uncomfortable to ask, would it be alright if I helped you into a clean diaper? I mean, I did have you use your old one, so it seems only fair."

That question made the Alicorn's eyes nearly bulge out of her skull. "W-WHAT?!" she asked in genuine shock. "You... Y-You mean like... c-c-changing me?"

Even with Twilight's blush looking so apparent, Celestia kept her reassuring smile as she nodded her head. "It really wouldn't be a big deal for me. I am an older sister, after all. If I can change Luna's diapers when we were still mortal, I think I can change yours with no problem."

As Twilight's blush deepened, it was unclear whether the Alicorn's request was being received negatively or positively. She could tell that Celestia wasn't being disingenuous one bit, despite how unorthodox the moment may have felt. Even though she instinctively wanted to refuse the Princess' offer, Twilight couldn't deny that it was difficult to change herself (especially after soiling it so thoroughly). Maybe it was due to already having done so much in front of her, but Twilight couldn't put up much resistance before lowering her head and sighing in acceptance. "If... If it's not a problem for you, then... Th-Then I'd appreciate it."

"That's my girl," Celestia cooed as she hugged Twilight soundly with a smile. While her forelegs were wrapped around the Princess' back, one of her hooves reached down to stretch out the waistband of Twilight's padding. The younger Alicorn yelped a little in surprise, but didn't move much while Celestia inspected the inside of her diaper from above. "And judging by how messy you got, it seems like you really need a change~"

"C-Celestiaaaaa...." Twilight's blush practically exploded across her face in overwhelming embarrassment. "Y-You don't need to tease me about it!"

"I'm not teasing you," she stated in a much firmer tone after pulling away to lock eyes on Twilight. "I would never tease you about this." After a quick breath, Celestia's warm smile returned as she added kindly, "I just want to make you feel more comfortable with someone you trust."

Twilight took a calming breath as she processed that answer, but was unable to reply before she felt Celestia's magic wrap around her body and lift her off the ground. "And if you ask me," said Celestia in an almost cheeky-sounding tone, "I think the fact that a friend is willing to change your diaper as an adult is a pretty good sign of trust, is it not?"

As she was floated off the ground, the diapered Princess blushed with her lips pursed timidly. Meanwhile, Celestia laid the rubber changing mat atop Twilight's bed to avoid any accidental spills or stains. She then floated Twilight down gently, resting her on her back on top of the changing mat. After floating out the other essential items needed for the Alicorn's diaper-change, Celestia paused briefly to ask with a smile, "Are you ready, Twilight?"

Even with her heart racing in overwhelming nervousness, Twilight was able to exhale pertly before nodding her head with a blush. "I... I think so..."

Celestia nodded back with an approving smile, and used her magic to pull Twilight's hind-legs up and spread them apart. Another aura of the Princess' magic effortlessly pulled away the tapes that held the front of Twilight's diaper to its sides, ensuring that the padding could be opened without any problem. And due to how heavily soiled and soaked it had become, the weight of the padding made it so gravity opened the diaper before Celestia's magic could. The overbearing stench of Twilight's excrement was unmistakably rich and fetid, and caused both Princesses to wrinkle their muzzles in unison.

"O-Oh, my!" exclaimed Celestia with a chuckle as she pointed her muzzle away from Twilight's opened diaper, and waved her hoof a few inches from her snout. Not surprisingly, the inside of the Alicorn's padding was full with the lumpy, almost chowder-like consistency of brown mess that coated a large majority of Twilight's rump and nethers. While she knew it wasn't her worst outcome of a poopy diaper, Twilight still cringed in embarrassment that Celestia had to see something so unbecoming of her. Fortunately, the older Princess didn't seem too fazed after she fanned a good portion of the smell away from her muzzle. "Whoo! That's a smell I never thought I'd encounter again! But I must say, it looks like you did a very good job, Twilight~"

Twilight was understandably embarrassed, but she still smiled a little from that praise while blushing heavily. Given how heavy her diaper felt when she finished, she didn't need to look down to know Celestia probably saw a lot. But like a true professional, Celestia kept her composure as she floated over the package of Twilight's wet-wipes. She then used her magic to grasp the front flap of Twilight's diaper, and used it as an impromptu wipe to push the majority of the Alicorn's mess into the back of her soiled garment.

As she laid back with an awkward wrinkle of her muzzle, Twilight shivered a little at the feeling of somepony else's magic wiping her moist padding against her most sensitive region. While she was grateful to feel so much of her filth being cleaned off of her fur, the fact that Celestia herself was wiping her marehood made the moment feel unbelievably surreal. By the time her legs lere lifted even higher, prompting the Princess' rump to be fully lifted off the bedding, Twilight involuntarily tensed up as she felt her garment wiping against the mess caked on her cheeks.

"Therrrrrrre we go," said Celestia with a satisfied smile before folding the soiled front of Twilight's diaper inward inside the garment. The Alicorn's fur was still messily matted in a lot of places (particularly around the back of her thighs), but that preemptive wipe ensured that there wasn't too much mess for the wet-naps to handle. Celestia pulled out a couple of the damp, sterile-scented cloths with her hoof as she began to wipe between Twilight's legs first. "Hmmm... I'm surprised you're using one of the non-scented wipes for changes. Didn't I get you the kind with lavender?"

"Ummm..." Twilight wanted to be weirded-out about having a conversation with Celestia during her diaper-change, but she sheepishly shrugged before replying, "W-Well, uhhh... The smell was really strong, and it kinda made my sinuses flare up."

"What, more than the scents you made in this?" noted Celestia playfully. Upon seeing the sharp pout the Princess gave in response, Celestia paused her wiping to add, "Again, I'm not making fun of you. It's just--"

"Yeah, I know, I know..." Twilight sighed and laid her head back briefly. After a couple seconds, Twilight huffed with a light smile and chuckled to herself. "Y-Yeah, I... I didn't realize the irony of that statement until you said that."

"Well, I suppose I can understand how an artificial scent could be unflattering as well. I'll be sure to remember that next time I buy you supplies." Even as her wet-wipes graced along the sensitive lips of Twilight's marehood, Celestia showed no signs of discomfort or awkwardness while cleaning the Princess' matted fur. Meanwhile, Twilight had to bite her lip to keep from uttering any accidental noises in response to such a feeling. Fortunately, she was able to stay silent enough to ensure Celestia kept her warm and maternal smile while diligently wiping lower. "Are you feeling alright, Twilight?" she asked with a confirming gaze up towards Twilight.

"Y-Yes," blurted the Princess as she blushed and tried not to squirm too much within Celestia's magic. While she didn't want to worry or upset her mentor, she couldn't deny that Celestia's diaper change felt much less uncomfortable as she would've imagined.

In fact, it felt surprisingly nice.

"I just, ummm..." Twilight bit her bottom lip for another second, and breathed out in an attempt to calm herself down and speak somewhat honestly. "I'm just, uhhh... I'm really grateful you've been doing so much for me this past month. I mean, I wasn't sure what would happen after... after this all started."

"Well, what did you expect me to do?" asked Celestia with a coy raise of her brow. "Twilight, after all you've done to help me, my sister, and all of Equestria as a whole, I don't think it's saying too much to have me return the favor."

"Y-Yeah, but still..." Twilight couldn't help re-adjusting herself in Celestia's magic, even though her hind-end was fully suspended while the Alicorn wiped her cheeks with a clean wet-nap. She felt bad for still feeling apprehensive, but couldn't help saying with a shrug, "It just... It's not every day I have a Princess changing my diaper like I'm a foal."

Twilight blushed even deeper at saying such a thing out-loud, and her face grew much hotter when she overheard Celestia chuckle in response to it. "Yes, I suppose so," replied Celestia with an honest tilt of her head while wiping, "but there's nothing wrong with feeling embarrassed about it. Incontinent or not, you're still an outstanding mare who deserves the utmost respect. You might not be able to control your bowels, but you can control how you interpret that inability. Just like how you can interpret this diaper change as feeling good or bad."

Given Celestia's long life-span and worldly experience, it shouldn't have been a surprise that she could sense Twilight's flustered feelings. However, Twilight was able to take another breath in response while thinking that fact over. Fortunately, with the mess inside of her poopy diaper being covered with several wet-naps, the smell wasn't as strong to make her breaths feel forced or strained. Because of that, Twilight was eventually able to smile by the time Celestia wiped the last of the mess from around the dock of her tail. "Well, I... I can't really say this diaper change feels bad..."

After hearing Twilight's meek and honest reply, Celestia smiled warmly while standing before her laid-out form. "Well, I'm very happy to hear that, Twilight." She then used her magic to pull Twilight's poopy diaper out from underneath her, and begin folding it up with the tapes. Twilight wasn't able to see much, but she did notice her mentor slipping something inside of the soiled garment before it was rolled and taped shut. Celestia then pulled out a fresh, clean diaper to unfold and lay out beneath the waiting Alicorn.

"And, just a little powder first..." Before she could lay Twilight down into the plush padding, Ceelstia made sure to give her cleaned rear several good spritzes from the foal powder container. After Twilight's butt was properly dusted to avoid any rashes, her tail was slipped in through the small elastic hole just below the back of the waistband. "Andddddd in the front as well..." Celestia kept a studious smile as she lowered her former student into that poofy, clean diaper, and gave a good dusting of foal powder between her legs from the front.

Not only was Twilight impressed at the quality Celestia's diaper change felt, but also from how quickly she did it. When it was just by herself, it'd take at least five or ten minutes to get herself properly cleaned and re-padded. But as she felt the Alicorn folding up the front of her diaper and applying the tapes, it felt like the whole process went by in an instant. Of course, Celestia didn't seem to notice Twilight's surprised expression by the time she taped her diaper up securely, and gave the front of her dry padding a confirming pat of her hoof. "There we are~ One special diaper change for Royalty, by Royalty~"

Twilight giggled with a hoof over her mouth, not expecting Celestia to make such a corny joke. "W-Wow! I... I really don't know what to say to that."

"You don't have to say anything, Twilight." With a kind and motherly smile, Celestia pulled Twilight back up so she was sitting on top of her mat in her fresh diaper. She then said with a sincere and reassuring tone, "And just so you know, if there's anything you need help with, you know Luna and I would be more than happy to help. Even if it's another diaper change~"

Twilight's blush intensified in an instant, and she huffed in surprise while looking away from her embarrassedly. "O-Oh! Ummm... W-Well, I..."

She wanted to say something respectful, like how that kind of offer wasn't necessary. Even though that diaper change felt great, she couldn't fathom asking her or Luna for another. But after a brief exhale, the Princess' mouth opened on her own to reply involuntarily, "I really would like that~ EEP!"

While Twilight gasped and covered her mouth with both hooves, Celestia just laughed kindly and nodded her head. "Well, as long as I can fit it into my schedule, I can see what we can do until your incontinence issue is fixed."

Twilight bit her lip as she looked away and feebly nodded, even though she felt frazzled by such an offer. Considering how her incontinence might be permanent, that assurance from Celestia felt nothing short of significant. However, even as her mind was racing with various thoughts and feelings, they were temporarily paused when she saw her used diaper being floated to the nearby trashcan. Upon recalling what Celestia did earlier, she felt prompted to ask, "W-Wait, ummm... I... did you put something in that diaper before you rolled it shut?"

"Hmm? Oh, that..." Celestia kept a casual smile as she shrugged her head and tossed that diaper into the bin. "I bought Luna's birthday present recently, and I didn't want her to find the receipt. She might be good at snooping around, but I figured she wouldn't go rooting around in that."

All that Twilight could do was shake her head with a sigh, and smile while rolling her eyes in response. "Wow. I honestly thought I was the only one who did that."
