Diamond Tiara's Padded Secret

A Diamond In Training

Previous ChapterNext Chapter

Diamond Tiara continued to sob into Randolph’s chest. Normally she would hate to let anypony see her in such a weakened state, but this was a situation under which she could do nothing but cry. All those precautions she’d taken, all the efforts she’d made to keep her secret a secret, and yet a careless mistake on her part was all it took to ruin it.

Now her reputation was sure to be in shambles. Randolph was certainly going to tell her parents who would certainly not approve of such an interest. And her relationship with Randolph would never be the same again.

But much to the magenta coated filly’s surprise, minutes ticked past and yet even as her sobs diminished Randolph had not moved an inch. Neither had he spoken a word. He had just been gently rubbing her back, like he used to do when she was an actual foal and not dressing up like one. Against her better judgement the filly slowly ceased her crying, dried her eyes, and looked the old buttler firmly in the eyes. “You’re…not going to say anything about this?”

Randolph nodded as he offered his young charge a tissue to blow her nose. “Mistress Diamond, how long have you known me?”

“Since I was two, I think.” Diamond commented before she stopped to blow her nose.

“And in all the years I’ve known you, did I ever once betray you or otherwise turn my back on you?” Randolph inquired.

Tiara slowly replied with a shake of her head. “N-no, I guess not. I remember you cared for me a lot, more than Mother or Father did. You gave me bottles, held me in your lap, even changed my diapers. And even after I made you do all those acrobatics, you still supported me.”

Randolph nodded again. “Exactly, Diamond Tiara. From the day you were brought home from the hospital, I have always felt a personal attachment to you. A bond that goes beyond just the simple obligations of my job here,” And he smiled. “Seeing you like this certainly brings back memories. May I ask what brought all of this on?”

Diamond gulped. The filly wasn’t sure if she wanted to tell anypony about why she did this, let alone the pony who could easily turn around and blab to either of her parents if he so chose. But he seemed to have a sincere smile on his face. It didn’t seem like he had any intention of telling anypony about this. And she supposed there were worse ponies who could’ve seen her like this (she shuddered at what might’ve happened had one of her friends walked in on her like this. She especially feared the teasing remarks from Apple Bloom and Scootaloo who she’d used to bully).

“If you don’t wish to tell me, that’s fine. I shall depart and leave you to the privacy of whatever it is you like to do in this current state,” Randolph informed the filly as he stood up. “I assure you that not a word of this shall leave my lips. It will just be our little secret. After all, everypony has them.” He gave a knowing wink.

But before the butler could take even five steps towards the door (which was thankfully locked), something took hold of the filly and she reluctantly blurted out. “I guess I just like being a foal. I like to feel young and carefree, like I don’t have any big pony responsibilities to worry about. It’s an entire process,” She sighed. “I don’t know exactly what brought it on. All I can remember is that one day, all of a sudden, I looked at baby ponies and something inside me started wishing I could be like them. I saved up my allowance and bought all the supplies in secret.”

“Even the diapers?” Randolph inquired, having no concerns using the term.

Diamond shook her head. “The local foal store doesn’t sell diapers in my size, and I couldn’t risk buying from Barnyard Bargains,” She reluctantly admitted as a raging blush formed on her cheeks. “I bribed Pipsqueak to let me borrow some of his, since I kind of found out he was a bedwetter. They’re really intended more for a colt, but they’re the best I could do.”

“You could've snuck into Barnyard Bagains with a disguise. With the right amount of effort, nopony would've norlticed it was you.” Randolph suggested.

Diamond Tiara shook her little head and replied back with. “No, it's not that easy and it was way too risky… I'm not really great with disguises, Scootaloo and Apple Bloom seem to be, but I'm too afraid to ask them.”

“Ah, I see.” Randolph nodded but said nothing more.

The pink coated filly tried hard not to gulp. “I’m sorry you had to find out about… all of this, Randolph. This is definitely not something a rich pony like myself should be indulging in, as I’m sure my mother would be saying right about now.”

It was then Randolph adopted a most unexpected expression. He seemed to adopt an almost fatherly smile as he approached his still padded charge. “But Mistress Spoiled isn’t here now, is she?” When Diamond shook her head he added in a tone that sounded more like a parent than an old buttler. “And don’t all foals need a mommy or a daddy to care for them?”

It didn’t take a genius for Tiara to realize what Randolph was implying. “You want to be my… my…” She paused and trailed off, almost unable to bring herself to say what came next. “...Daddy?”

Randolph cooed as he trotted towards the diapered filly. “Of course. If that’s alright with you, my little Diamond.”

“You’d really be okay with all of this?” Tiara asked the old buttler. “You’d treat me like a foal? Even play with me, feed me, and…” She gulped. “Change my diapers?”

“If and when it comes to that, yes. After all, that’s why you have all those changing supplies, is it not?” Randolph inquired.

Tiara reluctantly admitted. “I have kind of used them once or twice. Only for number one of course, number two would be way too much of a hassle.” She made a gag face to indicate her displeasure.

“Then I suppose that’s where the line shall be drawn,” Randolph replied as he scooped the filly up. “But while you’re in my care I expect you to tell me when you need something. After all, you’re a foal now and foals are too little to care for themselves.”


Diamond was soon smiling as she felt Randolph inspect her padding with a hoof, finding it dry. She was a good little foal, she didn’t wet herself uncontrollably. And because she was so good at staying dry, that meant her pajamas got to be zipped up before she was placed down on the floor. Of course the bulge in the back of her pyjamas indicated that her diaper was still there. And the crinkles it gave off with every step she took also reminded her of its presence, no way was she going to forget.

Randolph was content to play the part of an observer for the time being, letting his young charge explore her surroundings to her heart’s content. It really made him feel as if he’d stepped into a time machine and traveled back several years. “I’ve almost forgotten how adorable the young mistress used to look in her diapers and pyjamas,” He thought with a smile. “Guess I’m just a sucker for a cute face. Especially when it’s attached to such an adorable body.

Tiara soon opted to slow her movements right down to a crawl, largely because her diaper pushed her legs apart considerably. Such was the trade-off for having such thick diapers, but then again thick diapers meant poofy diapers. Lots of padding to protect her and hug her rear for warmth. Besides, crawling made her feel even more infantile. Especially with that pacifier she had now popped back into her mouth.

Feeling safe under Randolph’s watchful eye, Diamond crouched down beneath her bed and pulled out a huge assortment of carefully concealed foal toys. Rattles, alphabet blocks, plastic tools that squeaked when you hit them against something, even those shaped blocks that went into different holes.

The pink coated filly alternated between her toys, often coming back to the brightly colored rattle. The store clerk had told her it was magical, intended to calm even the fussiest of foals. Diamond had brushed off the comments, but now it was easy to see that the clerk hadn’t been lying. Shaking the rattle always produced a calming effect, like all her worries melted away. She probably would’ve been drooling a little if not for the pacifier.

But whenever she could manage to set the rattle aside, Tiara would crawl as slowly as she could to whatever toy attracted her interest. After a while she began to arrange some of her alphabet blocks and when she was finished she took the pacifier out of her mouth to call to Randolph. “Look, Daddy!” She called as she adopted the best foalish sounding tone she could manage. “I spelled out your name!”

Randolph looked at the carefully arranged blocks and smiled. They didn’t spell out his name, but they did spell out from left to right “D A D D Y” and that was good enough for him. Like a parent rewarding their child for their first words he cooed in exaggerated fashion. “Oh splendid, splendid!” He clapped his hooves. “What a smart little foal I have!” He trotted over and picked her up, tickling her little hooves as he cooed. “Who’s a smart little filly? You are! Yes you are! Yes you are!” He even opted to briefly blow a raspberry into the foal’s exposed tummy, watching her kick her hooves in delight.

Tiara howled with laughter. “Stop!” She pleaded with fake worry when in fact she wanted nothing more than for the tickling sensation to continue. It felt so nice to feel loved and cared for, she didn’t want the affection to ever stop.

Unfortunately, just as the tickling drew to a close (so that Diamond could catch her breath) the filly became aware of an all too familiar need. It was faint for the time being but it was growing by the minute. There was no mistaking it. The subtle twinge in her bladder. The filly remembered that she’d polished off an entire juice box at lunch and it had been a few hours since then. And now it seemed to be on its way out. She groaned and bit her lip as her face became scrunched up.

Randolph knew from experience what that face meant. “Does my little foal need to go pee pee?” He commented in exaggerated fashion.

Diamond removed her pacifier, her cheeks blushing anew. “You want me to use my diaper?”

“Only if you really want to, Diamond. I wouldn’t want to make you uncomfortable,” Randolph offered. “The lavatory is just down the hall. I’m sure we could probably make it in time if we hurried. Though it may not be wise to hold it in for that long.”

Tiara still blushed. “But I’ve never used my diaper in front of another pony before, not even accidentally,” She paused and tried to think, which was hard when her bladder kept reminding her of its need to be emptied soon. “I mean, I have plenty of diapers and it would be a shame not to use them. But… I’m not sure I can just go. The times I’ve tried it’s taken me a while to actually do it. Guess years of potty training can be thanked for that, not that I regret them. Can’t stay in diapers forever.”

“Well,” Randolph suggested as he held his young charge. “Maybe there’s a way we can make it easier, if you’re sure you want to use your diaper.”

Reluctantly, Tiara commented. “You’re my daddy in all of this. Daddy knows what’s best for his foal.”

Randolph nodded. “Very well then. Let’s give my idea a whirl.”


A short time later, the old butler had effortlessly carried Diamond (still in her pyjamas) to the bathroom. So as to give her privacy he had locked the door behind her.

The old buttler stripped his young charge down to nothing but her diaper, setting her pyjamas aside for later. Then he lifted up the lid of the toilet and carefully placed Tiara on the seat, letting her legs dangle as her diapered rear was planted firmly over the bowl. “Since you’re so used to using the potty, perhaps it will be easier for you to do what you need to do if you’re sitting on it,” He explained. “It’ll be just like using the bathroom as normal, except your diaper will obviously be the destination and not the porcelain throne itself.”

Tiara sighed even as her blush refused to go away. Now she really felt little, like she was in potty training and her mom was forcing her to sit on the potty until she did her business. This time was different, or at least it felt different. So why couldn’t she bring herself to do it? Why was her body still fighting against her? She was on the toilet, sitting just like a normal pony did. Her body should’ve been able to determine that. Was it really so hard for her to use her diaper, even with Randolph’s encouragement?

The stallion got an idea as he noticed his padded charge still struggling to go. He leaned over to the nearby sink, turning on the tap and letting the water flow from the faucet. “Concentrate on the flowing water. Think about it and not your diaper,” He encouraged. “I’ll even look away if it makes you feel better, just let me know when you’re done.”

Diamond sighed, took a deep breath, and closed her eyes. She tried to envision a flowing stream, like the river near Ponyville that Sweetie Belle’s father often frequented to fish. She concentrated on this vision and blocked out all distracting thoughts to the best of her ability. It took a while but her efforts were eventually rewarded as she could just make out an ever so faint hiss amidst the continuing flow of tap water. She didn’t try to hold back, she tried to let it happen naturally as her thirsty padding eagerly absorbed the waiting drops as they slowly cascaded out.

But after only a little bit and much sooner than she would’ve liked it, it all ended. Tiara was quite displeased. She knew there was more than that. Her bladder was nowhere close to being empty. Yet no matter what she tried to do it seemed like she just couldn’t bring herself to fully let loose. Reluctantly, she sighed. “I...I’m done.” She admitted, sounding much more like a potty training toddler who hadn’t even tinkled than a filly trying her hardest to use her diaper.

Randolph turned off the tap and inspected the padding from afar. “Seems like you hardly went. Are you sure you’re not holding back?” He questioned his charge. “It’s not good to be doing so, you could get an infection.”

“I’m trying, Daddy,” Tiara profusely apologized. “I don’t know why nothing’s working. I guess maybe my potty training is too instilled me in for me to go against it.” But just as soon as she finished saying that, her bladder finally stopped holding back. The floodgates opened and an audible hiss could be heard as her padding start to soak up the steadily flowing drops. Diamond blushed as Randolph quickly turned his head to give her privacy.

After only a minute or so (but to Diamond the process had felt like hours) the hissing stopped. Diamond’s bladder was completely drained and no longer ached. Her padding had acted like a sponge, greedily sucking up the whole soaking. And yet on the outside, aside from the faded hearts it was impossible to tell that anything was different about it.

“Are you done, sweetie?” Randolph cooed. His voice sounding much more like a parent asking their potty training toddler.

Tiara reluctantly nodded. “Y-yeah, I guess I am.” She didn’t dare to move (not that she really could’ve), still trying to process what she’d just intentionally done. She was still thinking about it as Randolph picked her up.

“My goodness, you completely drenched this one!” Randolph exclaimed in only partial exaggeration. “These diapers are clearly of the utmost quality if they can hold up after a soak like that! We’d better get you changed right away before you get a nasty rash.”
