Diamond Tiara leaned up over the side of one of the many small bridges scattered around Ponyville, staring solemnly down into the creek below. There were many other bridges that cross the small rivers that run through the town, but this one was special to her.

She tended to visit it whenever she was feeling depressed or particularly upset about something going on in her life. It gave her a place to vent her problems and frustrations while not having to worry about being overheard by anypony. This side of town was in was not visited much, and most of the residents who lived in the surrounding houses usually weren't home or remained indoors most of the day.

Ever since patching things up with the Cutie Mark Crusaders, Diamond Tiara had been visiting this little bridge less and less frequently. The CMC listened to her problems without any complaint and, with their help, usually ended up discovering a new way of resolving them. The source of today's problem, however, was a different story. Her current conundrum was not something she was willing to go and tell just anypony about, even her closest friends.

Even after the many years since getting her cutie mark, Diamond Tiara still wore diapers to bed every night. Every morning she would wake up with either a heavily soaked or messy diaper, sometimes even both! Thankfully, she'd been able to keep this a secret from everypony outside of her own parents, even from Silver Spoon. Diamond didn't think she would ever be able to handle the embarrassment that would be brought on should any other ponies ever find out about her embarrassing secret.

Thankfully, her father had always been very supportive, always telling her that she had absolutely nothing to be ashamed of. Filthy even went so far as to purchase her diapers from a special discreet source, ensuring that nopony would ever find out that she was getting them.

Her mother, on the other hand, was the exact opposite of understanding. All Spoiled seemed to care about was how much of a detrimental impact Diamond's secret could have on her precious 'public image', should it ever become public knowledge.

This last week, in particular, had been especially bad. Her father was gone on a very important business trip all the way in Manehattan and likely wouldn't be back in town for a while. Whenever her father wasn't around, Spoiled was usually a lot less willing to put up with Diamond's problem, constantly bringing it up at home to shame her.

But one of the things that bothered her the most about her father being gone was Spoiled's blatant disloyalty to her marriage. Whenever Filthy went away on long trips, it wasn't uncommon for Spoiled to just leave for days at a time. The strange smells and bags of bits that usually followed her made it pretty easy to tell that she'd been messing around with other stallions.

When her mother found out that Diamond knew what she was really doing, Spoiled began making ominous threats when they were alone together.

"It certainly would be unfortunate if your friends were to ever learn about your dirty little secret, now wouldn't it? I suppose we both have some very important secrets that we would both like to keep from reaching certain pony's ears."

Her mother's cold words bounced around inside Diamond Tiara's head like an echo that refused to go away. What she was going to do? She hated living like this.

As Diamond was thinking, a sudden a glint of light in the water caught her eye. She allowed herself to be distracted by the glare, enabling her to take her mind off the worrying thoughts. Below, she spotted something shiny resting at the bottom of the creekbed, hiding among the many small rocks and pebbles.

Squinting, Diamond tried to make out just what the thing was but she couldn't gather anything more than it appeared metallic. Curiosity taking over, she walked off the bridge and trotted up to the water's edge to get a better look. It almost looked like some kind of necklace though most of it was buried beneath the rocks.

'Did somepony drop it into the river by mistake?' She wondered.

Reaching down into the cool stream she was just barely able to loop the exposed portion of the necklace around her hoof and pulled it up to the surface. Taking a better look, it was indeed some kind of jewelry and had a large amulet attached to it. The necklace appeared to be made from silver while the amulet itself was made of some kind of large purple gemstone.

The gemstone had been carved to resemble the shape of a pony's head but it had no mane or particularly detailed features. Two small green gems acted as the eyes of the mystery pony. It certainly didn't look like anypony in town, so there was no telling if it belonged to somepony she knew.

'Weird...' Diamond thought, getting a weird vibe from the object as it rested in her hooves.

While at first, it had seemed a bit creepy, there was also a strange... allure at the same time. Without much hesitation, Diamond shrugged and allowed the necklace to fall around her neck, the amulet hanging from it coming to rest right over her chest. For some reason, just from having this thing on, it made her feel more... confident. Holding up the amulet with a hoof, she flipped it over to reveal some kind of carved text that was inscribed in small lettering on the back.

'That gent 'r the lady who is't wears this charm shall beest able to bendeth the shall of oth'rs'. She read, bewildered by the strange words and hornwriting.

She couldn't quite understand what the words meant as many seemed like they had been written in an entirely different language. It gave her the distinct impression that the necklace must've been pretty old. She let the amulet drop back against her chest.

Looking up, Diamond realized that it was starting to get late as the sun rapidly approached the horizon. She would have to get home fast, lest she has to face her mother's wrath.

As the troubled filly wandered back towards home, she failed to notice the faint green glow that was now coming from the amulet's eyes...

Diamond Tiara sighed as she walked through the large gates that surrounded her father's mansion. The Rich residence stood out quite a bit from the rest of Ponyville as most houses around town were made purely from wood and straw. They didn't have any actual butlers or maids, much to her mother's annoyance, but they didn't really need them anyway.

"I'm back," Diamond called as she walked in through the front door, pausing to peer into the living room where her mother lay back in a chair.

She was drinking from a glass of wine, and from the smell, Diamond was able to deduce that it had come directly from Filthy's special collection. The kind that was normally reserved for very special occasions.

"Hmph! About time you got back. I have another meeting in a few minutes that I must attend and I fully expect you to remain in your room while I am gone." her mother said, not even turning to look at her.

'No doubt another stallion for her to 'satisfy'...' Diamond Tiara inwardly groaned.

"What were you even doing, running around out there? You'd better have been up at that pigstye of an apple farm, playing with those awful blank flanks that you seem so fond of now.

"No mother, I was looking for Silver Spoon... but she wasn't able to play with me today." Diamond lied, making her way towards the stairs. The last thing she wanted was for her mother to find out about her only private sanctuary.

"Well, I can't say I blame the girl for not wanting to see you, especially if she were to ever find out about that disgusting little defect of yours." Her mother scowled, taking another sip of wine.

Diamond Tiara hated it when her mother called it that. It made her feel like she was inherently flawed from birth or something, which was probably exactly how Spoiled actually saw her anyway. Her mother hadn't always been this bad, but ever since Diamond Tiara stood up to her at school, she was absolutely merciless.

"Now, get up to your room young lady, and I better not find out that you tried leaving the house while I'm gone!" She warned, turning around to glare at her daughter. "And get rid of that tacky-looking necklace you're wearing. I'm sure you found it in some dumpster next to that horrid boutique at the edge of town. No daughter of mine will be seen wearing anything of the sort!"

A sudden surge of anger ignited within Diamond Tiara, the glowing amulet's eyes intensifying.

"No, I won't!" Diamond shouted back at her mother. "Its probably worth more than you anyway!"

There was a fire in her mother's eyes as she got up from her chair, clearly outraged that she dared to talk back.

"How dare you speak back to me like that you disrespectful little tramp! Don't you forget who is in charge while your father is away!" Her mother scolded, storming over.

Diamond Tiara could feel a rage boiling inside of her that grew with each passing second.

"You may have been able to pull that little stunt at your school, but I will not tolerate that kind of attitude in my house!" Spoiled yelled, slamming her hoof down.

A surge of foreign magical energy, fueled by her anger, flowed into Diamond Tiara from the amulet around her neck, drawing Spoiled's eyes down towards it.

"Und'r mine own controleth!"

A demonic chant seemed to force it's way from Diamond's mouth, a spark of green energy flashing behind her eyes. Two beams of green energy shot from her pupils, slamming into her mother who had been watching the light show with wide eyes concerned eyes.

Almost instantly she froze in place, a vacant and emotionless expression washing over her as a strange hum hung in the air. After a few moments, Spoiled blinked a few times and looked around. Shaking her head, she looked down seemed surprised to find Diamond Tiara standing in front of her, still glaring angrily as the green light faded from her eyes.

"Why, Diamond honey, whatever is the matter? Tell me, Is there anything I could do that would make you feel better? Anything at all?" She asked, sounding surprisingly sincere.

The anger Diamond Tiara had been feeling drained away as she rose an eyebrow to her mother's strange words, her anger quickly being replaced by confusion.

'Why is she acting so concerned all of the sudden? Is she just being sarcastic?'

But before she could inquire, a green shimmer of light drew Diamond's eye's downwards. She gasped upon discovering that her amulet had changed shape. Instead of a dark maneless pony, it now looked just like her, complete with her signature tiara and everything! Just about the only thing that was different was the eye color which remained dark green.

'What in Equestria?!'

"Diamond? Are you feeling alright, honey?" Her mother asked again, sounding genuinely concerned.

"Huh? Uh, yeah, I'm... fine... What were you saying?" Diamond asked, utterly bewildered.

'She's never called me 'honey' before... what in Equestria is going on?'

"I asked if there was anything you would like me to do for you. I want to ensure that you feel happy after all."

'...What...'

"Why are you acting so nice?!" Diamond demanded, wary of this all being some kind of trick.

"Well, because you're my master, of course." Spoiled replied, as that were a perfectly normal thing to say.

"W-what!? What do you mean master?"

"It is my utmost desire to attend to your every want and need, my daughter. I am your personal slave to command" She explained.

"S-slave?!"

"Why, of course. I would do anything if it pleased you," She said with a nod, dipping into a low bow in front of her.

Diamond Tiara was at complete a lost for words. One minute her mother had been yelling and arguing and the next she was now bowing and claiming to have become her own personal slave? Diamond's eyes widened in realization and she looked down at the amulet hanging around her neck. Her likeness's eyes pulsed with a strange glowing green energy.

'Did you do this?'

Looking back up, her mother was still waiting patiently, a strange almost sensual look in her eyes that Diamond had never seen on her before.

"I want you to... go into the kitchen and make me a peanut butter and jelly sandwich." Diamond commanded nervously.

If this all this was some kind of trick then this would surely reveal it. Spoiled Rich, for whatever reason, had always despised simple foods like that, apparently believing that they should only be eaten by the 'lower class peasant ponies' while she only ate the highest quality meals available. Yet that didn't seem to be of any concern to her now.

"Of course." Spoiled replied, trotting past Diamond Tiara and making her way down the hall towards the kitchen.

Bewildered, Diamond followed behind her, eager to see if she was really going to fulfill her request. There was something else Diamond had thought to have her do, but if this was real, PB&J was a good first test. She didn't want to overdo it, just in case the spell, enchantment, or whatever the amulet placed on her was to break somehow.

As she followed behind her mother, Diamond blushed upon noticing something else that was abnormal about her behavior. Spoiled's tail was being raised high in the air, fully exposing her smooth marehood and puffy ponut that was normally hidden underneath. If nothing else, this confirmed the legitimacy of the amulet's influence. Her mother sheltered that area of her body like it was her life savings.

That is, of course, as long there wasn't another rich stallion around for her to mooch off of. While it wasnt completely uncommon to catch glances of another pony's privates, seeing her mother exposing herself like this was pretty jarring. An odd tingle ran down Diamond's back as she found herself stealing more and more glances at her mother's ample flanks.

'...Must be why father puts up with her all the time...'

Diamond Tiara sat in the same chair that Spoiled had been sitting in only a few minutes ago, enjoying a pristine plate of various snacks, all prepared perfectly. So far, her mother had done every little thing she'd asked her to do and was currently fetching her some juice from the fridge. As Diamond Tiara took a big bite out of her PBJ sandwich, she considered what this recent turn of events could mean.

She could have Spoiled admit everything she has done to her Filthy when he got home... but that felt like such a waste. She wanted to have her do something more, but what exactly?

As if on cue, her mother trotted back from the kitchen, carrying a cool glass of orange juice in one hoof. Diamond ad instinctively thanked her for each thing she did, but every time her mother would insist that the thank yous were not necessary.

"Hey, Mom?"

"Yes, honey? Is there something else you would like me to do for you?"

"Yea actually... Can you tell me what you were really planning to do later today?" She asked curiously.

"Why of course. I was going to meet with a rich and handsome stallion I met about a year ago. I've been having a secret affair with him for a while now." She explained calmly, outright admitting to her adultery.

'I knew it!'

"However, I will no longer be doing that as I will instead remain here to serve you, my beloved daughter. After all, you are far more important to me."

It felt nice hearing her mother tell the truth about her hidden activities for once. Still, Diamond felt like she wanted at least a little laugh at her mother's expense. And in fact, she knew just what to have her do first. If she was remembering right, there was a package of adult diapers sitting in her closet. A few weeks ago one of her secret diaper shipments had included a pack of them by mistake and they hadn't gotten rid of them yet.

"Alright mom, next, I want you to go upstairs to my room and put on one of those adult diapers that are in my closet!" Diamond commanded, chuckling from the mental image of her mother wearing a diaper.

'Ha! This'll be good!'

"Right away master." Her mother replied, turning and heading upstairs.

'That whole 'master' thing does feel a bit weird though...'

Diamond Tiara watched anxiously as her mother cleaned the living room, all the while wearing a thickly padded diaper around her flanks. She was expecting to find this funny or at the very least embarrassing for Spoiled, but for some reason, she didn't. Instead, the sight of her mother wearing a diaper made Diamond feel... weird. It might have had something to do with her being magically okay with it, but there was something else that was contributing...

"Master?" Her mother suddenly called from across the room, waking Diamond from her thoughts.

"Huh? What is it, mom?"

'That's weird, she hasn't asked me anything before."

Spoiled seemed almost unsure of herself, fiddling with the feather duster between her hooves as if she were scared to say something.

"I-i have an outfit hidden away upstairs that may fit well with the task you've given me. If you don't mind, I'd like to go put it on?"

Diamond was surprised by how flustered Spoiled was about her request. Paired with the diaper she had on... it was kinda cute.

"Uhh, sure, why not."

"Thank you so much master!" Her mother sighed in relief, bowing once before rushing back upstairs. As she passed by, the crinkling sounds of her diaper aroused more strange feelings in Diamond Tiara. It was fuzzy odd, uncomfortable, feeling in her stomach, not unlike how she sometimes felt around a few colts at school...

"So, w-what do you think?" Spoiled nervously asked a slackjawed Diamond Tiara.

Her mother was wearing a full-fledged black and white maid costume, complete with a little hat. She still had on the diaper too which was easily visible from the side and behind.

"I lov- I mean, I guess it looks pretty... nice" Diamond said, unsure how she really felt about seeing her mother in such an outfit.

"Thank you, master, I'll get to work right away!"

Her mother bowed again, beaming as if she had just been complimented by Celestia herself. She then grabbed the feather duster and got back to work dusting the entire room from top to bottom. All the while, Diamond couldn't keep her eyes away from her mother's diapered behind.

'Why is this bothering me so much? I should be laughing at how ridiculous she looks, not thinking about how nice it looks on her.'

A few minutes passed as she continued to watch her mother clean a majority of the furniture in the living room. Every time she bent down, Diamond found herself unable to look away. It was really bothering her now.

She was just about to have her Spoiled take the diaper off and do something else when she heard a faint hissing sound. Her mother had stopped dusting and wore a very relaxed and relieved expression on her face. The source of the sound became evident as her diaper slowly started to expand, absorbing the liquid streaming into it.

'My mom, the infamous Spoiled Rich, is wetting a diaper, right in front of me...' Diamond Tiara realized in stunned silence.

Unable to say anything or to take her eyes off the now slightly yellowed diaper, one of Diamond Tiara's hooves began to slowly drift downwards of its own volition, approaching her nether regions. Eventually, the hissing sound began to die down as the lower portion of her mother's diaper sagged between her legs. After a relieved sigh Spoiled seemed to finally notice that she was being watched and her cheeks turned red.

"P-please, forgive me, master! I-i just felt the n-need to go so I-" She stammered, shaking as if she were a little filly that had done something bad.

"D-don't worry about it, just... keep cleaning." Diamond quickly commanded, a determined tone in her voice as she openly began rubbing a hoof over her marehood.

"Y-yes master, right away!" Her mother said with a bright blush as she immediately got back to cleaning. The diaper audibly squishing as she squeezed the wet padding between her thighs.

'W-why...why is this turning me on?!' Diamond shouted in her mind, shocked as she realized just what she was doing. 'Why I am getting off to my own mom peeing herself in a maid outfit!?'

Yet despite this bizarre realization, she only sped up her movements. Diamond's eyes suddenly clamped shut as a spike of pleasure rippled through her whole body, a moan forcing itself from her mouth as she rode the wave.

"D-diamond?" She heard her mother say, causing Diamond's eyes to shoot open again.

"I'm sorr-"

But she was abruptly cut off as her mother's lips suddenly made contact with her own. A wide-eyed Diamond Tiara held up a hoof to push her mother away but then all resistance to the unexpected kiss melted away as their tongues started to intermingle with each other. She felt Spoiled's hoof make contact with her wet little marehood, stroking up and down. Unable to last very long from the combination of stimuli, Diamond climaxed, moaning loudly into her mother's mouth as her whole body shook. Her legs shuddered and spasmed from the crash of pleasure.

After almost a full minute, they finally broke apart, a long string of saliva connecting them as they both panted breathlessly.

"M-mom?"

"I-i'm so very sorry, my master, but I simply couldn't resist you any longer, please forgive me!" She begged, looking down with a shameful expression.

"No, its... fine, that was... very nice," Diamond panted, almost delirious in disbelief of what had just happened.

"Thank you, dear. I always do my very best to please you."

*Grumble*

"Urgt" Spoiled suddenly grunted, reaching down to hold her stomach.

"Sorry, my master, but I'm afraid I'm feeling a rather urgent need to relieve my bowels. I know that I've have asked a lot from you, but would you mind if I did so in my diaper?"

"N-no, I don't mind! Just... turn around so I can watch."

"Of course, master." She said, turning around so that the still soaked diaper was now facing her daughter.

Face skewed, Spoiled grunted as she started to push.

*Pwwfffrprpt* She gasped as a loud and very wet fart ripped out of her.

Diamond watched intently as after a few moments a bulge appeared in the diaper as her mother pushed out her load. The diaper grew larger as more and more of mess came out, quickly filling up the inside of Spoiled's diaper. Reaching out with a hoof, Diamond pressed it up against the center of the padding, feeling the content smushing against her mother's sensitive privates.

"Ohh!~" Spoiled moaned.

She was quick to climax from the rubbing and spreading of her messy load. As she was bathing in pure extasy, her legs gave in, causing her to collapse in a heap in front of Diamond's chair, very messy diaper sticking straight up in the air.

'...Maybe I won't have you tell father what you've done...not yet anyway. I think I have a much butt punishment in mind, one that both of us will enjoy...'

The amulet around Diamond's neck continued to glow brightly, her own eyes now glowing as well...

The rest of the week was very good for Diamond Tiara. She didn't feel troubled anymore and her mother was tending to her every need and desire. And as an added bonus, she was no longer wetting the bed! At least by accident anyway...not that she would need to tell her father about that. Still, she wanted to make sure that once he did return from his trip, he would come back to the loving wife he truly deserved...
