It's been a few years now since Pound and Pumpkin Cake outgrew the need for diapers, and Mr. and Mrs. Cake have found themselves starting to feel the ever so fainting yearnings to be young again. But they've never found the time to truly act on those feelings: Until now.

Upon learning by chance that the twins will be spending the night at a friend's house, and that Pinkie Pie is out of town due to a friendship emergency, the Cakes suddenly find themselves with Sugarcube Corner all to themselves. And Mr. Cake has come up with the perfect way for the old couple to spend the evening.

Since the old bakers can't turn back the clock and aren't willing to experiment with spells, the next best way to feel young again is to act like foals. To that end, Mr. Cake talks his wife into the two of them wearing diapers, and doing all the things foals do. Together, the old couple will see if they can't make themselves feel young again, if only for a single evening.

There's been only a handful of AB/DL stories and AB/DL art featuring the Cakes, and just about all of them have made Mrs. Cake the more active of the two when it comes to just about everything. So I wanted to turn the tables and give Mr. Cake a chance to be more of a leader for a change.

I'm well aware that this could very easily be intrepreted as a clop fic and could probably have easily been written as one. But I have no experience with that genre and do not wish to delve into it, so I will say that this is not meant to be a clop fic, it is meant to be a wholesome romantic fic in the same vein as Raving Rocks or Sun, Stars and Padding.

Turning Back the Clock

The faintest of sighs escaped the lips of Mrs. Cake as she went about the daily task of baking various sweets and goodies to satisfy the sweet tooth of the customers. It was another busy day at Sugarcube Corner, but as busy as it was it still gave the plump baker time to think about things. And there was one thing that, try as she might, she could not stop thinking about. She was thinking about her children, the twins Pound and Pumpkin Cake. Had it really been that long since she'd brought them home from the hospital? Seems like only yesterday they'd been born, yet now they were old enough for school and barely seemed to acknowledge either their mother or their father. Seemed like it would only be a matter of time until they got their cutie marks.

Mr. Cake was working nearby and happened to notice the sigh from his wife, as well as the slight slump in her posture. Naturally, being a married stallion, he was concerned that something was wrong. So he not so secretly made his way closer to his wife, delicately reaching out a hoof to get her attention. "Sugar plum, what's wrong?"

Mrs. Cake spun around and nearly flinched! She tried to recover as best she could. "N-nothing's wrong, honey bun. I'm just... feeling a little sad, that's all. But I'm sure it'll go away."

The lanky stallion didn't seem to be satisfied with Mrs. Cake's reply. "Come now, Cup, you know you can talk to me. What is it that's got you so sad? I promise not to tell anypony else. This'll just be our little secret."

The plump baker sighed once again and bit her lip to keep from groaning. Try as she might, she could not hide her feelings from her husband. So, hesitantly, she confessed. "I was just thinking about Pound and Pumpkin. I know this sounds crazy, but I really miss the way they used to be: All cute and innocent, and always looking up to us. Now, it feels like they hardly even know we exist. They always seem to be in such a rush."

Mr. Cake let out a sigh of his own. "I know what you mean, Cup Cake. I know they couldn't stay as cute little foals forever, they had to grow up and stop being babies sooner or later," He frowned and his lips began to quiver. "But it feels like they're growing up too fast. Has it really been that long since we decided it was time to get them out of diapers? It's like we blinked, and they completely changed before our very eyes."

"I know," Cup Cake lamented as she nevertheless tried to resume her baking. Unhappy as she may be, it was no excuse to neglect her responsibilities to all the hungry customers. Yet even as she threw herself back into preparing the savory sweets, she couldn't help but keep on prattling back to her husband. "Don't get me wrong: I'm glad we did all those things for them. And I'm sure they do still love us. I've no desire to turn them back into foals again, not even just for a day. That wouldn't be right."

Carrot Cake nodded back as he too started baking again. "No it wouldn't, sugar plum. Even Pinkie Pie probably wouldn't want that. Still, thinking about the twins, it really does make you realize we're not getting any younger."

"Yes," Cup Cake unhappily agreed. "If only there were some way to fight that feeling? Some way to feel young again, if only for a day. Preferably, a way that didn't involve magic."

That got Mr. Cake to thinking. He started recalling a memory long since passed, but one that had buried itself deep inside his mind and was now resurfacing. At the time, he'd thought nothing of it because it had come and gone so quickly. Now, however, his wife's comments were making him think of it again. Maybe that was the answer to the problem that now presented itself. But could he convince Mrs. Cake to give it a try? More importantly, could they find time to truly test it out? What about the twins? And what about Pinkie Pie? How would he and his wife keep them in the dark and prevent them from finding out?

Well, those were thoughts to keep thinking about. For now, the lanky stallion knew he needed to focus on his baking. What was most important right now was that Sugarcube Corner stay in business. There would be time to experiment and explore such a possibility later. In the meantime, the needs of the hungry customers took priority.

Slowly but surely, the lunch rush at the bakery eased. The crowds died down to a much more manageable level. Things would likely not pick up again, at least not until all the foals came home from school. Pound and Pumpkin were sure to have told all their classmates about how Sugarcube Corner was the best place to go to get something sweet after a long day of classes, homework, and other things that school aged foals always found boring.

Meanwhile, Mr. and Mrs. Cake finally had a chance to rest their weary bodies. Baking for so many ponies was demanding and exhausting work. When they were younger it hadn't seemed like a problem at all. Now, however, even when Pinkie Pie or the twins could help out, it felt like it took everything the earth ponies had just to keep up with the demand.

Neither elderly baker had much time to rest, however, before an all too familiar pink colored blur came whizzing in and out of the bakery! "Sorry, Mr. and Mrs. Cake!" The familiar voice of Pinkie Pie briefly managed to blurt out! "Twilight needs my help: Friendship emergency! Gotta go!" And in the blink of an eye, she had disappeared.

Carrot and Cup weren't bothered in the slightest by Pinkie's sudden declaration. They'd long since gotten used to it and had accepted it. Whether it was a party, a friendship problem, or something else entirely, Pinkie was prone to up and disappearing at a moment's notice. Chances are she wouldn't be back anytime soon.

And about half an hour or so after Pinkie Pie's abrupt departion, Pound and Pumpkin Cake came home. And they too seemed to be in a hurry, quickly dumping off their saddlebags as they said in unison! "Hi Mom, hi Dad! Bye Mom, bye Dad!"

"Where are you two off to in such a hurry?" Mrs. Cake demanded of her children with a slightly impatient tone of voice.

"We've been invited to our first ever sleepover, we're staying the night at a friend's house!" Pound Cake eagerly declared as his wings poofed out to either side of him in excitement!

"Yeah, so there's no time to talk! We already did all our homework. We'll be back first thing in the morning!" Pumpkin Cake nodded as she then turned to her twin brother. "Come on, let's go!"

"You don't have to tell me twice!" Pound Cake chuckled as he and his twin sister raced away together as fast as their hooves would let them.

Mr. Cake smiled even as he sighed ever so slightly. "Those two really do take after Pinkie Pie a lot. No wonder they look up to her so much."

Mrs. Cake chuckled. "I know, but I wouldn't have them any other way. It warms my heart to see them making friends. Pinkie's sure to throw them a party when she finds out."

Carrot Cake nodded, before his thoughts turned to a sudden realization. "Well, I guess that means we'll have Sugarcube Corner all to ourselves for the evening, Cup, my dear."

At that Cup Cake let out a gasp, as if the realization had only now struck her! "Oh my gosh, you're right, Carrot! We should do something special to celebrate, because I can't remember the last time we were this lucky."

The lanky stallion then said as the gears in his head started to turn. "I think I know just the thing, sugar plum. And it should be a way to make us feel young again."

"What are you suggesting, honey bun?" The plump baker questioned with an odd mix of concern and curiosity.

After looking all around to make sure that nopony was around to overheard, the earth pony stallion carefully leaned close and whispered into his wife's ear. "Do you remember the first time Pinkie tried to buy diapers for the twins and how she ordered 'the thickest, most absorbent diapers possible'?"

A blush formed on the earth pony mare with a cobalt blue coat's face. "I thought we threw those away!" She exclaimed even as her tone of voice betrayed her intentions.

Mr. Cake couldn't help but snicker, chuckling not unlike the way a child might do. "Thought I'd hold onto them and donate them. But I couldn't find a way to do it without drawing attention to ourselves, and I didn't want ponies to get the wrong idea about us."

"You really think that those... things are going to help us feel young again?" Mrs. Cake questioned. From the way she was talking it was starting to become clear that she was more excited about the prospect than her questions let on.

"Well, think of it as being in a play," Mr. Cake proposed. "We'll put on the..." He whispered again. "Diapers, and act like little foals. We'll do everything the twins used to do when they were in diapers. And since we'll have Sugarcube Corner all to ourselves, nopony but us will ever know what we did."

Cup Cake somewhat nervously asked in reply. "Does that mean we'll have to actually..." She coughed into a hoof. "... You know?"

Carrot Cake just vaguely replied. "We'll cross that bridge when we come to it, sugar plum. But that's what the twins used to do before we potty trained them. If we could survive that, I'm sure we can handle using our diapers for a bathroom. We'll just need to be careful about getting rid of the evidence afterwards. Wouldn't want anypony finding out."

"Y-yes," Cup Cake nodded back, struggling to suppress a guilty smile. The thought of having a secret that only her and her husband knew about was so exciting, so alluring. "Don't know how we'd even begin to explain such a thing, especially not to the twins."

"Which is why it's a good thing they're not going to be here," Mr. Cake whispered back. "So whaddya say, Cup Cake? Interested?"

The plump baker did not hesitate to reply. "Oh, you could sweet talk me into anything, honey bun," She teased with a wave of her hoof and a swish of her tail. "Just remember that this was your idea, not mine."

The lanky stallion snickered and grinned. "I'll remember, dear. But let's save this talk for later, like say after we've closed up shop for the night."

Mrs. Cake was delighted to agree. "Okay, Carrot Cake." And then she and her husband went back to baking, preparing themselves for the rush of little ponies they knew would be coming by the bakery at any minute.

Perhaps because the two elderly earth ponies now had something to look forward to, something that was equal parts exciting and concerning, work seemed to fly by for them. Before they knew it, Sugarcube Corner was ready to be closed down for the rest of the evening. And once it was locked up tight, the fun and excitement were ready to begin!

Mr. Cake took his wife by the hoof after his eyes scanned his surroundings, making sure there was nothing they were forgetting about and that nopony was around to see what they were about to do. Above all else, he wanted this to stay a secret between the two of them. He knew from experience how fast gossip traveled even in a town like Ponyville: Once a secret was found out, it didn't stay secret for very long.

The two now off-duty bakers gingerly made their way upstairs, until finally they arrived in their bedroom. There, Mr. Cake closed the door behind him. He knew he didn't really need to, but the extra layer of security added to the mood and the allure of having this secret to share with the pony he so loved and trusted. Once that was taken care of, he carefully poked his head under the bed that he and his wife shared, and slowly pulled out a very large box. Printed on it in large letters were the words: Silly Filly Super Deluxe Adult Diapers: For the biggest of big foals

Mrs. Cake gasped in spite of herself! She could still remember when that box had been delivered all those years ago, and how embarrassed Pinkie Pie had been to find out she'd ordered such a brand of the padded undergarments by mistake. Fortunately, it had all been resolved before anypony else had the chance to find out. Yet now, here was that same box again, still unopened. It was a bit dusty, and the lettering was faded a little. Otherwise, it was in the same overall condition it had been in when it had been delivered.

Mr. Cake carefully opened the box, exposing the diapers inside. Despite the years, they still retained their pristine white color. And there was no mistaking them, they were clearly intended for ponies the same size as Mr. and Mrs. Cake. There was simply no way you could've gotten these to fit onto a normal foal without having them be completely engulfed by the padding.

"Shall we?" Carrot Cake proposed as he held out a diaper in one hoof and with another hoof ran over the soft, crinkly surface, delighting in how it felt.

Cup Cake nodded. "Better let me put a diaper on you first, honey bun," She replied with a tease and a knowing wink. "If memory serves, your first time trying to put diapers on a pony went very poorly."

"As if you were any better, sugar plum!" Carrot Cake playfully teased, yet he still cooperated. He lay down on the bedroom floor and spread his legs apart. This was it, his wife was about to diaper him. And then he was going to do the same thing to her.

The earth pony mare with a curly mane and tail the same coloring as cupcake frosting approached her husband, taking full possession of the diaper he'd previously been holding onto. Even though it had been years since she touched (let alone changed) a diaper, it all seemed to come flooding back to her in an instant. In a matter of seconds, she had the diaper fastened around her husband's rump and had it taped up securely.

The lanky stallion slowly rose to his hooves. He initially struggled to get used to the added weight hugging his rear and how it pushed his legs even further apart. "Of course," He thought to himself. "They're the extra absorbent kind. They're meant to be bigger and poofier." Fortunately, after waddling clumsily around for a little bit, he had mastered the art of moving around in diapers to an extent that satisfied him. He then carefully helped his wife to lay down on the bedroom floor and diapered her, repeating the motions he'd seen her use on him. His motions were not as delicate, not as precise. But he didn't seem to care.

Like her husband, Mrs. Cake at first found the weight of the diaper to be difficult to get used to. But after waddling around for a while in a much more delicate manner than her husband, she felt that she had the movements down pat. However, there was something nagging at the back of her mind. "Hold on a minute," She pondered aloud. "Aren't we forgetting something, Carrot, darling?"

"Forgetting?" Carrot blinked. Whether he was actually confused or just pretending to be was impossible to tell. As he tried to think, he stuck a hoof into his mouth and started to suckle on it. He expected to be grossed out at doing such a thing, to yank his hoof right out of his mouth and dry it off. But something in the back of his mind prevented him from doing so, something in the back of his mind told him it was acceptable to do such a thing.

Cup pretended not to be annoyed by her husband's inability to give her a satisfying answer. So she just giggled instead. "You must be really out of practice if you've forgotten already, my dear. We need to add the baby powder." She trotted over to a cabinet at the other side of the room, bending down and exposing her padded plot that swished and swayed as she slowly pulled open a drawer. Inside rested all the diaper changing supplies from when Pound and Pumpkin Cake were still in diapers.

Carrot Cake pulled his hoof out of his mouth as he asked his wife. "I thought you threw out all that baby stuff once we got the twins fully potty trained."

Cup Cake adopted the most guilty face possible, almost like she was a little filly who'd been caught with her hoof in the cookie jar. "There were just too many memories attached to them for me to throw them away. I held onto them in case we ever decided to have more foals," She sheepishly admitted. "Guess it's a good thing I did. Now we'll be all set for if we have to actually..." She coughed into a hoof. "Well, you know." Then she pulled back her own diaper, held the bottle of foal powder aloft, and sprinkled in a generous helping. She delighted in the infantile scent it gave off.

Mr. Cake playfully pouted, folding his hooves across his chest and pretending to look annoyed.

Mrs. Cake cheerfully trotted over, still holding onto the bottle of foal powder. "Don't worry, Carrot, there's more than enough for both of us." She soon sprinkled in a generous helping for her husband. Too generous, in fact, because the powder spilled out through the leg guards and got on the floor. Oh well, that was easily fixable and could be cleaned up later. After all, when little ones made messes they didn't know how to clean them up.

"And let me guess," Carrot said with a playful grin as he eyed his wife. "You didn't actually donate those old toys the twins used to play with, did you?"

Cup's smile brightened. "I thought you were gonna do it, dear." She replied in a voice most unconvincing.

Carrot played along. "Wait, was that supposed to be me? I thought you agreed to do it when I was the one who threw out the diapers?" He dramatically put a hoof to his forehead. "Now what shall we do? We've got all those old toys just laying around somewhere. Nopony's gonna want to play with them now."

The plump baker playfully retorted. "How about us, honey bun? I'd say those toys are just right for ponies of our size now. It would be a shame to let them go to waste, wouldn't you agree?"

The lanky stallion nodded back. "Oh yes, we wouldn't want that, now would we?" He briefly broke from character, sweetly whispering to his wife. "I knew you'd have fun with this, sugar plum."

"Don't thank me, it was your idea," Mrs. Cake waved a hoof and tried not to blush. "Besides, the night is young and we are not."

Mr. Cake giggled back. "Speak for yourself, I'm already feeling at least fifty years younger. Who would've thought diapers could have that kind of magic?" Then he watched as his wife opened up another drawer in the cabinet, revealing well worn toys that the twins had long ago outgrown. They were your typical toys for foals: Rattles, squeaky toys, stuffed animals, alphabet blocks, you name it. Some of them looked a bit dusty, and a few of the stuffed animals were missing an eye or looked like they were barely holding together. Yet that didn't matter to the two diapered earth ponies as they took possession of them.

Time itself seemed to slow to a crawl, figuratively and literally. The Cakes grabbed whatever toys caught their interest, and left the rest scattered about the bedroom floor. They wished more than anything the nursery from the twins' baby years was still intact. But alas, that had been torn down the day it had outlived its usefulness.

Oh well, the bedroom was more than suitable enough as an imaginary nursery. Mr. and Mrs. Cake delighted in sitting down to play with the toys, distracted only briefly by the clouds of foal powder that billowed up from their diapers. At least they wouldn't have to worry about a rash (neither had any idea how they would explain such a thing to anypony).

Mr. Cake only occasionally stopped playing to suckle on his hoof again. "If only I had a pacifier that could fit my mouth," He thought. "Then I'd really look the part." But there was no way they made pacifiers big enough for full grown ponies like him and his wife. And he wasn't about to take an old pacifier and have it be enlarged via magic, that was a surefire way of attracting unwanted attention.

Mrs. Cake mostly occupied herself with the stuffed animals. Each one had scents that she associated with memories of the twins from their fledgling years. Oh how long ago they seemed. Yet every time she held one of the stuffed animals close and closed her eyes, she could picture the memories as if they had just happened yesterday.

Eventually, however, the plump earth pony mare grew bored of playing with the stuffed animals. And since her husband seemed to be in no real rush to play with them either, she decided to just leave them where they were. Maybe she'd come back to them later. For now, however, she grabbed some of the squeaky toys and started absentmindedly banging them over and over again on the bedroom floor. The noise created from doing so seemed to echo everywhere, but she didn't care. She was having the time of her life.

The earth pony stallion was delighted as he watched his wife play to her heart's content. His idea seemed to be working out well so far. Was this all that was needed to make them feel young at heart?

Carrot's thoughts were interrupted, however, as a faint but familiar sensation made itself known. It was a slight tingle in his bladder. Come to think of it, he couldn't recall having gone to the bathroom since before lunch time. He briefly stood up, eyeing the bedroom door. "I really should take care of this problem before it gets worse. Celestia knows I've probably been holding it in for long enough anyway." He thought to himself. It would be so easy to just trot to the bathroom and relieve himself the same way he'd taught his kids to do.

But Mr. Cake decided that he didn't want to do that. "Why waste a perfectly good diaper?" Then a more mischievous, dare he say naughty idea entered his mind. "Besides, these diapers are supposed to be really absorbent. Even more absorbent than ordinary diapers. Why not test them out?" So then and there he uncrossed his legs (only now realizing he'd been subconsciously crossing them as he'd weighed his options), and the stallion relaxed as he sat back down.

Unfortunately for the lanky stallion, his bladder didn't seem to want to cooperate. His potty training was so ingrained into him that his body simply refused to let go unless he was using a toilet. He tried hard to override such thinking, mentally straining himself in the process. Yet the best he could manage was a faint drop that was easily and readily absorbed by his diaper. He knew that wasn't enough, his bladder was nowhere close to being empty.

Mrs. Cake by chance happened to see the strained look on her husband's face, and seemed to know by instinct what was the problem. She stopped playing with the squeaky toys, sat up, and waddled over to her husband to check on him. "Something wrong, Carrot, sweetie?" She asked even though she was certain she knew what was going on.

Mr. Cake weakly nodded. "I really need to empty my bladder, but my body just doesn't want to cooperate."

The plump mare placed a hoof over her husband's body and instructed to him. "Close your eyes:" When her husband did so, she instructed. "Just try to picture running water: Like a stream, or a faucet."

"A-alright." Carrot Cake replied and did as his wife told him to. He sighed, taking a deep breath as he tried to conjure up the mental image. For what felt like several minutes, nothing happened. But his efforts were eventually rewarded when he heard a faintly audible hissing sound. Opening his eyes, he could see his diaper swelling up as a dark, damp patch slowly appeared and spread across the seat. Slowly but surely, his bladder emptied itself fully, causing his diaper to feel much warmer. A sigh of relief escaped his lips.

Cup Cake smiled in satisfaction. "That always helped with the twins. Feeling better now, sweetie?"

Carrot nodded. "You bet I am! Thanks, Cup."

Cup just took her hoof off her husband's body. "Any time, dear. Now excuse me." She subsequently spread her legs as she stood there, then closed her eyes as she appeared to be deep in concentration. Soon, the same hissing sound that had accompanied her husband's diaper wetting filled the air. Like with Carrot, her diaper slowly swelled up as a damp patch spread across it. And when she was finished, she opened her eyes and let out the same sigh of relief that her husband had made. Yet she had made the whole process seem so much easier.

Mr. Cake was utterly astounded! This whole thing had been his idea. And yet now his wife seemed to be taking charge. As delighted as he was to see that she was settling into the act, a part of him couldn't help but feel jealous despite having him literally zero reason to feel that way.

Just then, the stomachs of both diaper wearing earth ponies gurgled and grumbled quite audibly. However long it had been since the two had last eaten, it was clear to the old couple now that it had been long enough. Their bellies were empty and needed to be filled. That meant it was to eat.

Mrs. Cake giggled anew. "Guess it's feeding time, huh, honey bun?"

Mr. Cake giggled back. "It sure is, sugar plum," He immediately asked her. "You didn't actually keep all that food we used to feed Pound and Pumpkin Cake, did you?"

The plump baker shook her head from side to side. "Don't be ridiculous! How could I have justified it when nopony else would ever even touch that stuff? As soon as the twins were old enough for solid food, I threw that stuff away first chance I got. And I don't regret it!"

"And we don't have any high chairs or bibs," The lanky stallion sighed. "Oh well, I guess we'll just have to improvise, my dear."

"Enough talk, let's go get some num nums!" Cup Cake insisted as she and her husband both rose to their hooves. Their diapers now weighed considerably more than they had when they were clean, and the warm feeling was starting to fade. Still, they managed to clumsy waddle their way out of the bedroom and make their way downstairs to the kitchen.

The two elderly bakers opened the fridge together, eyeing its contents carefully as they tried to think of what to make for themselves. They knew they could have literally anything they might want, nopony was going to tell them otherwise. And there were all sorts of tasty, tempting desserts that made their mouths water just by looking at them.

In the end, however, Carrot and Cup decided that the sweets could wait, at least until after they'd had a proper meal. So they took turns picking vegetables that were then chopped up and cut up into little pieces, placed onto two separate plates.

"Gotta make sure we get our nutrition, right, Cup Cake?" Mr. Cake teasingly asked his wife as they took their seats at table.

"Oh, you're no fun!" Mrs. Cake teased right back as she and her husband sat down. They briefly worried that more foal powder might spill out or billow up. But thankfully, it had all seemed to settle in now, nothing came out.

The two diaper wearing earth ponies began eating the cut up vegetables in silence, pretending to be very reluctant to touch them and consume them. Slowly but surely, their plates were emptied. But neither of them felt anywhere close to full just yet.

Luckily, with a knowing wink, both Mr. and Mrs. Cake got up and retrieved the most tasty dessert they had laid eyes on: A huge bowl of chocolate pudding. They of course had to wait for it to thaw out, which in turn gave their stomachs time to settle. Once the pudding was thawed completely, they took the bowl to the table and set it between them. There was no need for spoons, they just ate with their hooves, the two padded ponies scooping up as much chocolate pudding as they could in one grasp and gobbling it all down quick as a flash. It didn't seem to matter to them how much of it they were smearing across their cheeks and faces, the pudding was too good to resist!

In the blink of an eye, the old couple had devoured the entire bowl of pudding. They leaned back in their chairs, licking the last bits of chocolate pudding from their hooves before patting their stomachs which now felt nice and full.

Mr. Cake couldn't resist letting out a big belch, his cheeks turning a faint shade of pink afterward. "Excuse me!" He babbled in the most childish sounding voice he could muster up.

"Good one, honey bun!" Mrs. Cake teased as her tail swished. Then she inhaled as she took a deep breath, before unleashing an even bigger belch from herself! "Oh, that felt SO good!" She exclaimed with wide eyed wonder!

Carrot Cake chuckled. "Oh yeah? Just get a load of this!" He proclaimed as he took the biggest breath he possibly could! Then, with hooves slammed down onto the table, he belched a belch so big and so loud he was surprised he had it in him! It was loud enough to make the whole ground shake, and he felt very relieved when no windows broke as a result. "Oh my, I think I overdid it a little." The stallion remarked as he couldn't stop himself from blushing.

Cup Cake grinned. "Oh my goodness! I don't think I could possibly top a burp like that! I guess you win this round, Carrot, my dear."

The lanky stallion flashed a toothy smile. "I didn't even know this was a contest. But I'll take the win all the same." Then he and his wife rose from the table.

The plump earth pony mare looked down at her diaper afterward and somewhat nervously asked her husband. "Do you think we should get changed?"

Carrot eyed his diaper and his wife's, and waved a hoof to dismiss the concern. "Nah, they look like they can hold a lot more. And we used plenty of powder, so we should be good for a little while longer. Besides, why change now when we're probably gonna have to do it again soon afterward?"

"Oh, right, what comes in must come out." Cup replied, her face flushing as she thought about the prospect. Yes, it was what little ones did, but that didn't mean it was something to look forward to. But she'd come this far already, why should that be the one thing off limits?

"We'll worry about 'cleaning up' later," Carrot Cake then insisted as he waddled his way over to his wife. "Let's go back upstairs and play, okay?"

Cup Cake nodded. "Whatever you say, Carrot. Lead the way." And she let him take her hoof into hers as they both waddled back upstairs to their bedroom.

Once back in the safety of their bedroom, the two elderly earth ponies briefly occupied themselves playing with the same toys as before. But they quickly grew bored of that, so while Mrs. Cake decided to spend her time playing with the alphabet blocks, Mr. Cake decided to "borrow" the stuffed animals and use them for something he'd always wanted to do: An imaginary tea party.

Minutes ticked by slowly once again as the now sodden diapers reminded the Cakes of their presence with audible crinkles. Yet they continued to play in blissful happiness and innocence, lost in their own little worlds.

Both Carrot and Cup were only snapped back to reality when they heard and subsequently felt an ominous rumble in their stomachs that made them clench. Pressure started to build up in their rears as their bodies were giving off very obvious signs of the need to relieve.

Mrs. Cake tried to ignore the feeling and concentrate solely on the blocks. She was so close to stacking the last one on top! She could hold it in until then, couldn't she?

Mr. Cake, for his part, had stopped playing pretend and turned to his wife. He could see her deep in concentration, standing on the tips of her hooves. He thought about sneaking up to her and distracting her, making her spill the blocks onto the bedroom floor. But he decided against it, instead opting to waddle off to a corner of the bedroom and wait for her.

Cup Cake groaned and moaned as the rumbles in her stomach grew louder, and the pressure built up to a point where it started to hurt. "Come on! Come on!" She muttered to herself as she tried desperately to fight the signals her body was giving off. Shutting her eyes and leaning forward ever so slightly, she placed her last block as best she could. Then she sat down, immediately crossing her hooves and trying to hold in what wanted so badly to come out! Upon opening her eyes, she saw that her efforts had paid off: Her block tower was complete, and not a moment too soon! "I did it, Carrot! I did it!" She applauded, taking great pride in her accomplishment!

Carrot Cake clapped his hooves, showering his wife with exaggerated praise! "Good job, sugar plum! You were amazing! I could never have stacked the blocks up as high as you did!"

"So now we're even! You had the bigger belch, I built the bigger block tower!" Mrs. Cake insisted with a swish of her tail. But then she groaned anew as the pressure and pain rocked her body. "Oh, Carrot! I really, REALLY have to go!"

Mr. Cake waddled close to his wife. "I do too, honey. Guess we shouldn't have eaten that chocolate pudding so soon after having those vegetables."

"I don't even think I could make it to the bathroom if I tried!" The plump earth pony mare nervously remarked as a bead of sweat trickled its way down her face! "But... what if it leaks?!"

The lanky stallion reassured his wife. "It won't. These diapers were meant for full grown ponies like you and I," He grabbed his wife's hoof and said to her. "We'll do it on three, okay? I'm sure we'll feel much better once we let it out."

Cup whimpered a bit, still understandably hesitant. Yet she managed to force out. "A-alright..." She quickly counted down. "One, two, three!" And taking a deep breath, she grunted and pushed as hard as she could! She was certain her husband was doing the same.

The diapered earth ponies were soon rewarded for their efforts, as their tails were raised upwards. Soon, an overpowering stench of manure and methane began to permeate the area. The diapers sagged heavily under the weight as a bulge built up in the back of both of them.

Thankfully, the whole process took only a minute or so. And the pressure had eased, both elderly bakers did feel just the slightest bit better.

"Oh goodness!" Mrs. Cake remarked as she fanned a hoof across her nose in only slightly exaggerated fashion. "I'd forgotten how bad it was when the twins used to do this. I don't know how Pinkie Pie could put up with it."

Mr. Cake just replied as he tried to breath through his mouth and not his nose. "W-well, at least this makes us feel younger, right, Cup Cake?"

Cup Cake struggled to answer. "I... guess it does. But right now I really just want to get changed!"

"Yeah, I kind of feel the same way," Carrot Cake agreed and gulped a bit. "S-since this was my idea, I suppose I'll wait and be changed second."

"Already on it!" The earth pony mare with a cobalt blue coat declared as she very slowly waddled across the room, grateful that as full as her diaper felt it showed no signs of leaking. Quick as a flash, she retrieved the wet wipes, the rash cream, and the foal powder, as well as two fresh diapers. She brought them over to her husband, who took possession of them all while she reluctantly lay down.

Sighing and taking a deep breath, Mr. Cake mentally prepared himself for the task that was to come. With his hooves trembling, he undid the tapes and let the diaper full from his wife's rump to the floor. He quickly balled it up, ready for disposal later. Then he grabbed the wipes and went to work. It felt like it took a long time to clean every trace of the "mess" his wife had, but he didn't want even the faintest reminder to linger on her coat. Once he was satisfied he'd done a good enough job, he sprinkled in a heaping helping of foal powder and worked in some rash cream, before fastening a new diaper to his wife's rump.

Mrs. Cake stood up very slowly and briefly walked around. "Not bad, dear," She said to her husband. "Now it's your turn. Ready?" When he nodded, she had him lie down on the floor. Quick as a flash, she had the old diaper undone and balled up, before going right to work with the wet wipes. She was much faster and much more precise with her movements, it took her considerably less time to finish, moving on to the powder and the rash cream, before finishing with a spotless diaper.

Now the only thing left to do was take care of the evidence. Mr. Cake quickly dashed off, returning shortly with a trash bag that the old diapers were tossed into without fanfare, alongside the used changing supplies. "I'll make sure to bury this with the rest of the trash so nopony ever finds out." He told his wife.

Cup Cake breathed a much needed sigh of relief. "With how much trash we'll be putting out tonight, I doubt anypony will notice anyway. But thank you for the offer, Carrot."

Carrot Cake was as good as his word. He had the trash bag with the dirty diapers inside it tossed out back and well hidden in the blink of an eye. Then he made sure to wash his hooves, confident his wife had waddled off to do the same. Then and only then did he slowly make his way back upstairs to their bedroom. Just from glancing outside while he was running the trash bag out, he could tell that it was getting pretty late. Even if Pinkie and the twins weren't likely to be coming back anytime soon, it would still be wise to clean up and call it a night.

Sure enough, the plump earth pony mare let out a sigh and yawned in spite of herself. "Don't know about you, Carrot Cake, but I'm ready to go to bed."

"Well, let's take care of that mess we left behind downstairs, then we can both get some rest," Mr. Cake nodded as he too yawned. And he and his wife slowly made their way back downstairs to do just that, taking great care to make sure everything was the way it had been prior tonight. It was highly important that nopony ever suspect a thing. In the midst of all the cleaning, he turned to his wife and asked her. "So, sugar plum, be honest. Was this able to work as I intended? Do you think it made us feel young again?"

Mrs. Cake was hesitant, deep in thought for a while. But eventually, she managed to reply. "I suppose it did. There were certainly some parts that were... unpleasant," The grimace she made made it clear what she was referring to. "If we ever were to do this again, I'd prefer to have somepony to take care of such things so we don't have to. And, ideally, I'd like to at least have the option of not having to actually use my diapers for a bathroom."

The lanky stallion managed to nod back. "I agree, Cup. If we ever do this again, and I don't see us getting this lucky again anytime soon, we should probably get somepony to be our..." He paused, trying to think of what word would work best. He ultimately settled for. "Well, I suppose 'caretaker' will have to do."

The plump earth pony mare giggled. "Do you think Pinkie would agree to that role if we asked her?"

Carrot Cake giggled back. "Probably not. She sees us as family, and I wouldn't want to complicate that. Besides, as much as she might have enjoyed foalsitting the twins, I can't imagine she'd want to come back to it again. I'm sure we'll think of somepony else who'll be perfect for the job."

The elderly earth pony couple then finished cleaning the last of the dishes, and thoroughly inspected the kitchen, the stairs, and their bedroom for any signs of anything they might have forgotten about. They found nothing. And so they waddled back upstairs, still diapered, and climbed into bed. Tonight had certainly been a night to remember.
