The past few months had not been kind to Lightning Dust. It turned out that getting yourself kicked out of the Wonderbolts - however justified it might have been - was somewhat toxic to your other career prospects. She was currently on her fourth shitty minimum-wage no-qualifications-required job - a fucking rent-a-maid. It wasn't quite rock-bottom (that was her very brief stint working at Bed’n’Burgers), but it was still plenty miserable.

At least, she mused as she walked up to her latest employer's address, they didn't make her wear some kind of creepy, fetishy outfit. Didn't stop creepy old stallions from ogling her ass, but it was better than nothing. She knocked on the door to the odd building, styled after a carousel. Who lived in a place like this, anyway? Artsy fartsy types, probably. The kind of pony who made more than she did sticking bowties on a fuckin’ garbage can.

She sighed. Whatever, they didn't pay her to care, just to clean. She dusted herself off and, with infinite resignation, rung the doorbell.

"Now where, oh where, did I put those fabric swatches?" Rarity muttered to herself, digging through a fourth pile of experimental dresses and half-finished projects. "Ick..." She made a face as she pulled out a withered brown lettuce leaf. The remains of yesterday's lunch, no doubt.

Oh, the curse of genius! She was normally so much tidier than this, but a full week of fashionable inspiration had taken its toll on her habits. The enchanted line alone had nearly driven her batty with stress, and it was nearly impossible for one to clean up after oneself when they were 'in the zone'... as it were.

Ding dong! Her ears perked as the doorbell rung. "Oh, thank goodness! The new maid." She practically ran to the door, thanking her lucky stars that past Rarity had had the foresight to hire another pony to help out. Someone to see to her cleaning while she focused on the creating! A more perfect match there could not be.

"Why, hello!" Rarity put on her biggest smile as she answered the door. "You must be, ah..." She cocked her head, eying up the plainly-dressed maidpony she'd hired. "Do forgive me if I'm mistaken," she asked, "but have we met before?"

Dust resisted the urge to cringe. Instead, she awkwardly adjusted her comfortable shorts - mostly hidden behind the practical apron that made up the entirety of her uniform - and picked at the shoulders of her tight-fitting tank top. "I'm Lightning Dust,” she said, dodging the question entirely. “You hired a maid, right?" She decided not to elaborate on who she was or how she knew whatever-her-name-was, one of Rainbow Dash's stupid friends.

"I did, I did!" Rarity pursed her lips, racking her brain to find the right memory. Something about this mare did seem familiar. A former customer, perhaps? A friend of a friend? It wouldn't surprise her if this - rather homely, if she had to be honest - pegasus was an old acquaintance of Rainbow Dash's. But where could they have met before? She didn’t exactly swim - or, ah, fly - in all the same circles Rainbow did.

"Aha!" Suddenly it clicked. "Lightning Dust! I remember,” she said, nodding sagely. “You were the one from the Wonderbolt Academy. I was so sorry to hear you were expelled. Rainbow Dash simply could not heap enough praise on your talents in her letters." She paused for a breath. "But don't let me dominate the conversation, darling! How have you been since then?"

Lightning smiled bitterly. "Yep! That's me. Got kicked out because some dumb civvies decided to fly a fucking hot air balloon into a restricted training zone and almost got themselves killed by a tornado. Dishonourably discharged. Kind of a shitty thing to put on your resume. Spent the past four months or so hopping from shitty minimum wage job to shitty minimum wage job and completely failing to hold any of 'em down. And now I get paid jack-all to get my ass stared at by creepy old fucks while I dust their shelves."

“Oh!" Rarity put her hand to her mouth, a spark of realization flaring in her eyes. "Oh my goodness, how dreadful!”

“Yeah…” This time, Dust did cringe. She'd let bad memories get the better of her and now she was probably going to get fired. Again. "Look, just... point me to what you need cleaned, ma'am," she muttered.

“Of course, dear, but… well, I didn't even realize you’d gone through so much! And all for our mistake. I promise you, I'll do everything - and I do mean everything - I can to make that up to you."

Already, the gears were turning in Rarity's head. What did she have that Lightning Dust would appreciate? A better outfit, certainly! She looked Dust over again, noting the awful, pained grimace on her face, her back hunched in a bored slouch. Being a maid was quite clearly not Lightning Dust's favorite occupation, nor even a tolerable one. She'd have to do something to fix that, too!

"Well, why don't you come in?" she asked, smiling warmly. "I'll show you where you'll be working, and then we'll see if I can't make things up to you somehow."

"Oh.” Dust had not been expecting that reaction. “Okay." She bowed her head meekly, following Rarity inside. "You don't, uh, have to do anything like that. Just don't fire me. I guess."

"No, I insist," Rarity said, quite pointedly. "It's partly my fault that you are where you are now, and as a lady, I consider it my obligation to help you make the most of your current situation." And with that, she took Lightning Dust’s hand, leading her all the way up the stairs.

"You'll see, darling. I used to know some ponies in the cleaning service myself. I know all the do's and don'ts to rake in the bits. Tips to get the tips, you could say!" She snickered as she guided Lightning over to the bedroom. The messy, messy master bedroom. "This is where you'll be starting," she said, clearing a small pile of pajamas out of the closet's way. "But first…” She stuck an arm in through the door, rummaging about for her favorite little project. “First, we'll have to get you out of that stuffy old uniform, and into something much nicer!"

A grin spread across her face as she found it. "Here we are!" The outfit seemed to sparkle, even in the dim bedroom light: a very frilly, very lacy, black and white maid's outfit. The sort worn by royal maids in Canterlot Palace itself. "Here, take it, please! It's quite clear that Rooms and Brooms doesn't care to dress their hard-working maids in the fashion they deserve."

Dust stared blankly at the outfit. It was everything she'd ever feared she would be made to wear. The skirt, black with a white lacey trim, was miniscule. Maybe two or three inches wide. The top was really more of a corset than an actual top, with frilly white shoulder pads. Dust decidedly did not want to wear the thing, but gingerly took it anyway, for fear of angering her current client. She didn't want to lose her job.

Again.

"Um. Thanks. Ma'am. I'll just, uh, put it on? Now?"

"Not just now, of course. I'll be stepping out for a minute to give you your privacy." Rarity's smile flickered as she noted the worried look in Lightning Dust's eyes. "And don't you worry, Lighting - may I call you Lightning? I promise I'll make you do nothing you don't want to. You don't need to wear it, but this is the creme de la creme for uniforms in your profession! I'm sure you'll love it once you try it on." She winked, already halfway out the door. "I can guarantee you that much."

"...Yes, ma'am." She stared after Rarity as she left, eyes lingering on her shapely form. Lightning had never really noticed it before - how could she have, really? - but Rarity was actually… somewhat attractive. The Academy had only ever been full of fit nuts. Ponies who cared more about trimming fat and dropping air resistance than their looks. Rarity, in comparison, was shockingly curvy. Voluptuous, even...

She shook her head. "Right. Better, uh. Better put this thing on? I guess?" She knew that Rarity had said she didn't have to if she didn't want to, and she very much didn't, but every point counted when it came to clients. Maybe, if she could get on Rarity’s good side, she’d finally have something approaching job security. She groaned in irritation - hopefully Rarity wasn't waiting for her outside, or she might have heard - and then undid her apron.

She tossed the apron aside casually, before moving on to her top. Absent a uniform from Rooms and Brooms, she’d chosen a tight tank top, cut to show off her tight, muscular abs - her best feature, as far as she was concerned. Her butt was tight and athletic, her hips slender and aerodynamic... and her chest decidedly not very large. A lifetime of being the very best there was had left her decidedly lacking in feminine allure, but at least her abs were fucking perfect. Dust wriggled her way out of her tank top - her tits were small enough that she didn't need any more support than that - and tossed it in the same direction as her apron, followed shortly by her shorts and panties, leaving her nude.

She picked up the white, frilly panties that came with her new ‘uniform’, holding them up to her eyes. They were decidedly symbolic of the outfit as a whole: frilled and lacey beyond belief, while paradoxically incapable of hiding anything whatsoever. She fiddled briefly with the dangling straps, wondering what purpose they could possibly serve, except to string her up like a ripe, holiday ham.

At least it wasn’t a thong, of all things, but it was still... decidedly translucent. Far more than she was comfortable with, especially considering how revealing the skirt was. Still, it was better than having to find another fucking job. And hopefully Rarity wasn’t particularly inclined to stare at her ass. Because otherwise, she was going to be able to see everything.

The thought sent an erotic tingle down Lightning Dust's spine.

Meanwhile, Rarity had run off to her dressing room for something more... comfortable. The public Rarity always dressed sharply - the finest in designer clothes, always - but while at work, Rarity kept it simple. Functional. A white tee and jeans hardly made for a glamorous combination, but it was easy to put on and practical enough for creation. "Lightning Dust?" She rapped gently against the bedroom door. "Are you done changing?"

"Eep!" Dust flailed in surprise, broken out of her reverie by Rarity's knock, tossing the panties in the air. "No! Uh, just a moment, I'll be out in a second!" Ideally, Rarity would not assume that she was having trouble putting on the corset-like top and barge in, but luck wasn’t on her side and never had been, so she decided to work fast. She deftly caught the falling panties and quickly slipped them on, before grabbing the skirt and attempting to put it on equally quickly - but, in her haste, she stumbled and fell face-first onto the bed, letting out a muffled cry and leaving her ass up in the air, pointed directly at the still-closed door.

"Oh, dear!" Rarity gasped. “Is everything alright in there?” She quickly checked herself over, magically smoothing out the wrinkles in her shirt to make it more presentable. Whatever she was wearing, Rarity took pride in her appearance - a lesson she hoped to pass on to Lightning Dust. She noted with pride the way even her simple white shirt brought out the best in her own personal curve. It had been just a hair too large when she'd first bought it, but a little time in the wash, and her dabbling experiments in growth magic, had made it almost form-fitting. She'd miss it quite dearly, after this was all over...

But oh, yes. Lightning Dust. "I'm coming in!" she called, opening the door up. A hot blush formed instantly on her cheeks as she saw Lightning's sculpted turquoise rear aimed right at her. "Oh..." Up went an eyebrow, a smile creasing up at the edge of her lips. That pegasus did know how to make that outfit work, after all. "Lightning Dust! I'm very... um, flattered!"

The panties were, Dust ruefully noted far too late, just slightly too small for her. They dug into her athletic ass and boyish hips in a manner more commonly seen on significantly more voluptuous mares. And she was so fucking horny all of a sudden. It wasn't much, but the panties were already slightly transparent, which in combination with her sexual fluids gave Rarity a view on everything.

"No! Um! I mean, uh- I just tripped! Is all!" She blushed furiously in her own right, clumsily pushing herself to her feet, leaving the skirt awkwardly lying on the floor beneath her. "Sorry. I'll, um, be dressed in a moment." Fuck. Well, at least Rarity hadn't taken advantage of her compromised position, the way she was certain some of her other clients almost certainly would have. As it was, though, Rarity almost certainly had the mental image of her juicy cunt stored away for a rainy day. "I'm, uh, just having trouble figuring out how this whole thing works."

"I understand completely," Rarity said, the blush still obvious on her face. Her nostrils flared as her other senses finally caught up with sight. Goodness, it had gotten steamy in her bedroom. The air was thicker and warmer than it had any right to be, laced with a sensual undertone of what had to be Lightning's arousal. She clenched her fists, heart pitter-pattering in her chest. Well, half the outfit's enchantment seemed to be working very efficiently. She could barely hide her grin at that much. And now for the other half. She picked the skirt up in her magic and laid it gently in Lightning Dust's arms. "If you could just finish up, though... Quickly, please?"

Dust blushed. "Yeah. Uh. One moment." She put the skirt on - this time at a less rushed pace, so as to not fall over again. The skirt was also very slightly too tight. Not enough to cause anything more than very mild discomfort, but still she struggled to get it over her ass and hips. "Ngh, hold on... guh. There. Now, uh..." She held up the next piece of the outfit - the corset. "Now, um. How do I put this on?"

The tingling subtly intensified, and though Dust’s body squirmed and fidgeted, her conscious mind hadn’t noticed.

Yet.

"Here," Rarity took the corset up in her magic, using it to adjust the lacing and her hands to direct Dust's arms. "Allow me." Slipping a corset on an uncertain customer was more or less second nature to her by now. A basic formality that left her attention free to focus on the most important details. She could feel Dust's arms expanding slowly, subtly beneath her fingers, slipping with every second over a fine sheen of sweat as Dust inched upward and outward.

A distinct, unmistakable scent of maleness began to seep into the room, the fabric of Dust's panties protesting silently down below. Rarity could feel her skin flushing, nipples hardening in her bra, a tingling, maddening itch in her crotch that needed to be scratched. Ooh, this enchantment was working perfectly. "Almost done, dear," she half-whispered, still manipulating Dust's arms like a mannequin... even as that mannequin was nearing a foot taller than herself. "Just the cap and stockings left. How are you feeling?"

"Kind of, um..." Lightning Dust inhaled deeply and exhaled slowly, her blush deepening. "Kinda hot?" She adjusted the cups of the corset in a futile attempt to make them dig in less. The fact that even the corset was slightly too small for her was almost baffling, considering how relatively flat she was. And that tingling was even more intense than ever before - stronger and stronger, until she could barely think of anything but. “Is that just me, or is your AC broken?”

"The air conditioning's working perfectly, darling," Rarity said, wiping the sweat from her brow. Truth be told, it was working perfectly. The ambient heat from an increasingly massive and horny pegasus pony, however, was just a little more than the ventilation could manage. “Perhaps it’s just you.”

"Oh. Well. I, uh. I'm fine, then. Just lemme put on the head thing and, uh." She grabbed the headpiece, frilly and lacy and perfectly white, and placed it on her head. "Um... and could you help me put these on?" She held up the stockings - hopefully this would distract her from her mounting arousal. Highly unprofessional of her to get so horny in front of a customer, as amazingly beautiful as she was.

"Goodness, do you need help with your stockings, too?" Rarity giggled, perfectly aware of Dust's... distractions. "I may have more to teach you than I'd thought!" Descending to Dust's nigh-loglike legs, she set about lacing up the thigh-highs. Good that Dust had decided to handle the cap herself. The pegasus’s head had nearly slipped out of arm's reach! "There we are!” She clapped encouragingly as Dust finished off with the headpiece. “Now,” she purred, “why don't you turn around? I'm sure you look positively stunning!"

Dust obediently twirled around, slowly and wordlessly, giving Rarity a good look at her still-growing body. The two mares had started out at around the same height, but now Rarity barely reached the pegasus's navel - and yet somehow the maid costume was still just slightly too small for her body. And what a body! Her tits, each easily the size of her head (and growing!) strained against the cups of the corset, each one just barely covering her fat nipples. The skirt dig tightly into her colossal hips, flesh bulging deliciously over its hem. The stockings, long enough to leave only a fraction of an inch of fur visible between their end and the hem of the skirt, clung tightly to her supple legs, showing off the delicate curves of her muscles. The silky panties were entirely consumed by her enormous, plush ass in the rear, but the real star was the view from the front.

There was no bulge. It was too big for that. The panties were stretched to their limit, barely a thread lining the divide between Dust's colossal teal balls, each one almost as large as her tits. Her cock jutted up proudly and erectly, long and thick and dark blue-green. It was long enough to easily nestle between her breasts, but sheer weight pulled it forward, the massive pole of flesh angled forward towards Rarity, drooling precum in a constant flow.

Lightning Dust stood straightly, almost elegantly. Professional enough to hide that her body was constantly quivering with a barely contained arousal. Still, one of her hands had drifted to her hefty sac, gently cupping it, just barely resisting the urge to fucking -squeeze-.

"What do you think, ma'am? Does it suit me?"

"Fits like a glove, darling," Rarity purred. "And it brings out all your best qualities!" She dabbed a finger ever so gently against the drooling tip of Lightning's cock, a long, sticky strand of pre trailing off along with it. She giggled as Lightning shuddered, even the lightest touch sending a ripple of pleasure up the pegasus's body.

Tentatively, she licked at her finger, her eyes widening as an electric tingle ran down her own spine. Salty, musky, and brimming with virility. If she hadn't been wet and raring to go before, she certainly was now. "Mm!" She sighed, resisting another taste. "I said we'd start you off in the bedroom, Lightning, but I think conditions may be a little too... cramped, for your comfort. Why don't we try the living room instead?"

She led the foggy-eyed Lightning Dust out the bedroom door, magic pushing her neck down just low enough to squeeze her through. "And there's no need to be so stiff and formal with me, Lightning. I may be your employer, but there's no need to call me ma'am, of all things!” She grinned. “Mistress Rarity will do perfectly well."

Once again, based on a lewd RP between myself and unideal, which seems to be a winning formula. Don't worry, we'll get to the good bits next time, I promise.
