Lewd Fashion Modeling with Twilight

>Be Anon
>Because of the fact that you constantly wore clothes, Rararara had taken a very real interest in you
>The unicorn thought it was wonderful that a species wore clothing casually, though she did think it was a little silly when you told her some people wear "clothes" when sleeping
>"There's wonderful and there's trying too hard, dear" she had told you
>Because of this, Rarity thought you were some expert on clothing
>You weren't; not even a little bit
>You even told the mare more than once
>She didn't seem to listen though
>Because of her, you had landed yourself a job as a clothing consultor
>Some clothing designs were tossed your way, you looked at them, pointed something that caught your eye, and Rarity would go ahead and start working
>It really wasn't too hard, more sitting around waiting for the mare to have a flash of inspiration
>A few of your picks were best sellers oddly enough
>Probably had something to do with that "alien stamp of approval" thing Sassy Saddles was pushing
>Not that you really cared though
>You liked helping your buddies, especially when they paid you way too much for stupid jobs
>At that moment, you were at one such job
>Rarity had called you just after 1 am, demanding you come over
>She had some up with some new designs, she had said, something for the upcoming fall season
>The mare seemed so excited about the whole thing you hadn't been able to get a word in edgewise

>So there you found yourself, half-asleep, splayed out on one of her fancy couches while she was working in the other room
>Somehow, she had gotten some pony to come here to help model whatever the outfit was
>"There we go! Now hold still dear. Just a few more stitches and... AH-HUH! Wonderful! Marvelous! Easily some of my best work!"
>You heard a slightly maniac giggle, which was follow by Rarity herself stepping into the room
>The mare had three different measuring ropes around her neck
>A little cotton ball filled with pins and needles sat on her back, and a marker was stuck behind her ear
>The unicorn looked tired, but happy as she pushed her red-rimmed glasses up her muzzle
>"Anonymous, darling, I would grab something if I were you, because I daresay this might just blow your socks off."
>She looked down at your feet, her muzzle scrunching in disgust
>"Though, those abominations could use a good blowing right into a fire."
>You yawned
"You made these socks, Rares," you pointed out.
>"To my utter shame," the mare said, placing a hoof against her head. "They look as if a novice made them. Truly that was a different time."
"You made them last week."
>"As I said, ages ago," Rarity replied with a flick of her tail. "But your ghastly socks can wait for another day. Twilight? Could you come here please?"
>A few moments passed before Twilight Sparkle, the biggest purple book horse that you knew, stepped into the room
>The alicorn looked tired, bags under her eyes and her wings drooping slightly
>"Eve--"
>She yawned
>"Evening, Anon."

>You yawned back
"Evening, Twi. So Rarity managed to rope you into this, huh?"
>The alicorn smiled
>"I'm happy to help a friend," she said, covering her mouth with a hoof as she let out another yawn
>"And what wonderful help you've been, darling," Rarity said, patting the mare's shoulder. "Now Anon, sit up. Up! You must see this."
>You did as you were told, sitting up as Rarity walked Twilight over toward you
>The alicorn was wearing black, see-through stockings
>They reached up to the mare's rump, displacing some of the flesh near the top, as it seemed that Rarity had made it a size too small
>Twilight also seemed to be wearing a pair of panties, made out of the same shiny black fabric
>They seemed well-made, though just like the stockings were a bit too small
>They strained against Twilight's big bottom
"A big small, huh?"you said
>"Well, yes. I must admit that they're a bit... snug," Rarity said. "I had made these with a... smaller mare in mind."
>Twilight's ear flattened against the sides of her skull
>Rarity noticed this, her eyes widening
>"Not to imply that you're FAT, dear, anything but, but I had not made those with an alicorn's figure in mind."
>Twilight looked back at her outfit, then over at you
>You responded with a smile
"You look great, Twilight. Pinkie promise," you said
>That seemed to brighten her mood
>She smiled, standing a little straighter
>"Thanks, Anon.

>Rarity coughed into a hoof
>"Yes, well, how does it look, Anon?"
>Twilight turned around, exposing her rump to you
>She even arched her back, really sticking it out there
>The fabric covering her marehood visibly tightened, swallowed between her cheeks
>You found yourself quite a bit more awake that you were a second ago
"I really like the frills," you said, reaching out
>You grabbed Twilight by the hips, pulling her back
>The mare flicked her tail, lightly smacking your nose as she sucked in a breath
"What material did you make these out of?"
>"The finest silk that I could find of course," Rarity said, puffing her chest out. "It's so fine that it simply kisses the skin. I'm going to be using the same fabric for a few more designs for this new line. It's going to be called "Kissed by an Angel"."
>You ran a hand across the underwear
>They felt really, really silky
>So smooth that you swore your fingers tingled
>Grabbing the top of the panties, you gave them a little tug
>Twilight tensed as the fabric further rode up, giving her a wedge
>With another tug you nestled the fabric between the lips of her marehood
>She let out a shaky breath, wings quivering as you traced the outline of her tailhole with your thumb
"Okay. So what's the gimmick for this one? Other than the cloth?"
>"A sensational one if I do say so myself," Rarity said. "This and the other articles of clothing I hope to make soon will help both mares and stallions alike relieve themselves while they are busy out and about!"
>Twilight flapped her wings as you continued to tug and yank at her panties
>The mare had always enjoyed your hands, even more than Bonbon, and you could already tell they were having an effect on her

>A noticeable wetness was collecting at the near the mare's groin each time your fingers brushed near it
>You noticed, however, that it wasn't staining the panties
"You do something to keep the underwear from getting soaked?" you asked, pulling Twilight a bit closer
>"Oh, you noticed? Yes, I managed to create a very special charm. It helps wick away any moisture. It should be able to handle a very sizeable load without any seepage."
"Where's the moisture go?"
>"Into another dimension, as far as I can tell."
>You stopped molesting the princess to give Rarity a deadpan stare
"Really? All that for some underwear?"you asked while Twilight let out a moan, grinding her rump against your knee
>"Nothing is too much for fashion, darling," Rarity replied, turning her attention toward Twilight. "So how does it feel, Twilight?"
>Twilight bucked her hips, eyes becoming hazy
"I-It feels... g-great,"she said with a wiggle. "Gonna cum soooooOOOOO--"
>She tensed, wings flapping as she stomped a hoof
>You placed a hand under her, helping keep her upright as she rode out her orgasm
>Twilight was usually a fast cummer--at least for you anyways--but her orgasm seemed to last shockingly long
>Maybe it was an alicorn thing?
>Twilight took a step back, then another
>Panting, she hopped into your lap, legs twitching and jerking as she continued to cum
>She turned her head to the side, licking your cheek as her hips bucked again and she let out a scream
>You rested your head on her shoulder
>Not able to help yourself, you slipped a hand into the still clean panties, slipping two fingers into the alicorn

>That had her thrashing, her marehood milking your digits
>You pumped them in and out of her, until Twilight went limp against you, tongue hanging out of her mouth
>Your hand was soaked, but the panties were still dry
>Twilight let out a groan as you pulled your fingers out of her, her hips rolling
"You know what, Rarity? I think these might be a big hit," you said, licking fingers your clean
>Rarity nodded, looking very pleased with herself
>"Wonderful! Now you simply must take a look at the male undergarments I've designed as well. Big Mac? Could you be a dear and come in here?"
>...
>Oh no
"Oh no."
