Prismatic Pheromones

This was torture. Sheer, unrelenting torture.

She knew she should have never agreed to it. She knew she would end up regretting it. But there she was; at the Carousel Boutique, perched atop a pedestal, wearing the girliest clothing Rainbow Dash had ever seen while Rarity applied the finishing touches. Only this time it was much weirder, and much worse. So much worse.

As if all the other times Rarity had dolled her up weren't bad enough, today took the proverbial cake. Around her mid section was a black corset that felt like it was squeezing the life out of her, with straps that buckled around her belly, and the tail of it fanning out around her rump. On said rump was a pair of black leather underwear. If you could even call them that, Rainbow had thought. They hardly covered anything! It was just a thin strip of fabric that wedged itself right up her crack. She couldn't so much as stretch without it rubbing against her bits.

To make matters worse still, this was not the first or last thing she had to wear. Piled up on the floor to the side was a mountain of saucy garments she had worn prior. Each one more revealing than the last. All together Rainbow must have had to wear well over thirty different outfits.

"Sweet friggin' Celestia, Rarity how much longer?" Rainbow groaned. "I thought when you said, 'just a few outfits', you meant like, three or four. Not three or four dozen!"

"Now now, Rainbow Dash, just be patient." Rarity chided. "You know you cannot rush this sort of thing. I assure just one more set after this and you'll be free to go, along with my eternal gratitude, of course."

"Ugh. Can I at least get some water or something? I think I'm actually gonna dehydrate wearing all of these stuffy clothes." she said, wiping sweat off her brow.

Rarity bit her lip to stifle a laugh. They both knew perfectly well that these outfits were anything but stuffy.

"But of course, dear. Just sit tight for a moment while I fetch you a drink." the unicorn said cheerily as she pranced off to the kitchen.

'Phew...good. I think she bought it.'

Rainbow sighed. She hadn't gotten nervous sweats like this since the Best Young Flyer's competition, and not since she was a filly before that. But as soon as the first pair of tiny pink panties snapped against her flanks, the perspiration kicked in and never let up. If that weren't bad enough, the smell she was giving off from it was pretty bad. She had honestly been surprised that Rarity wasn't complaining about it. Either way, Rainbow was tired and embarrassed, and she couldn't wait for all of this to be over and done with.

"Geeze, I need to take a load off. My hooves are killing me. I'm a pegasus for crying out loud, not a statue."

Rainbow's legs buckled as she mumbled to herself, landing on her belly and rolling on her side. The position change caused the skimpy undergarment to slide up again, it's smooth texture caressing her marehood and tailhole. She gave a stifled whimper as she felt her clit wink.

'Oh my gosh, could this get any more humiliating?

Rarity made her way back into the main room, glass of water floating next to her.

"Rainbow I-"

Rarity fell silent as her eyes landed on the perfectly sculpted, glistening hindquarters of the athletic speedster. The spotlight shined down on every delicate curve of Rainbow's toned ass, highlighted by the sheen of sweat that had accumulated on her coat.

'Oh...oh my. Keep it together now, Rarity dear. You've gone this long without making a fool of yourself. Even despite positively drowning in that...intoxicating aroma of hers. Just one more outfit and we can call it a day.'

Mentally steeling herself, Rarity cleared her throat.

"Ahem. Here you are, Rainbow darling."

"Thanks, Rarity."

Rarity felt another stir inside her as she met eyes with the pegasus. The flustered look on her face, her shimmering coat, and her frame wrapped up in the risqué ensemble was almost too much for her. She placed the glass at Rainbow Dash's hooves and quickly turned to grab the last ensemble.

Lacking any grace what so ever, Rainbow bit the rim of the glass and tilted her head back, chugging the cool liquid down as fast as she could.

"Alright then, Rainbow Dash. If you would be so kind and stand back up for me."

"Mmhmm." Rainbow abided as she quenched her thirst.

Rarity's horn lit up and began the process of undressing the pegasus. The sweat drenched fabric was audible as it was peeled away. Rainbow pinned her ears down, trying to block out the embarrassing sounds as Rarity struggled with her own uneasiness. Every layer removed brought with it a waft of the athlete's pungent aroma, sending the unicorn's heart racing. But it wasn't until the panties were removed did she get hit with a humid wave of Rainbow's feminine musk, nearly causing her to lose composure. After a bit more awkward fumbling, Rainbow at long last sported the new attire and the last outfit she would have to suffer.

"Rarity?! What the hay did you do to me?!"

The blush on Rainbow's cheeks glowed through her fur like a lighthouse beacon as she looked at herself in the mirror. On all four hooves were opaque white stockings with ruffled lace trim, the back pair stopping just below her butt. That same pair was supported by four garter straps leading up two what Rainbow guessed was supposed to be a pastel pink skirt. But it was so incredibly tiny she honestly wasn't sure. Underneath the skirt was a pair of matching pink panties, complete with a heart-shaped opening that framed her anus and vulva.

"It's the crown jewel of the entire line, if I do say so myself!" the fashionista announced proudly. "Simple, but alluring and...accessible." The last word ringing flirtatiously.

"Uh...Um..."

"Oh don't worry, darling. You shan't be in it long. After I add a few accessories I'll simply need you to strike some poses for me to make sure everything holds correctly."

"Fine, whatever. Can I ask you something though?"

"What is it, dear?"

"Are you like, making these for comfort horses?"

"Really now, Rainbow Dash." Rarity said, taking slight offense. "I'm merely expanding my work to include lingerie. Plenty of couples love having something to spice things up in the bedroom."

"And why me again exactly? Fluttershy's the one with the body to model this kind of stuff."

"Fluttershy has unfortunately been preoccupied with a new litter of baby rabbits." Rarity said as she pulled out a box of small bows from a nearby drawer. "But to be perfectly honest, Rainbow Dash, your figure is much more suited to these sorts of garments. I know you don't like to hear it, but you have a gorgeous physique that is the envy of many a mare."

Rainbow still with her ever-present blush turned her head and grumbled. "Lucky me. But...thanks, I guess."

"Honestly, I'll never understand why it's so difficult for you to embrace your feminine side." Rarity huffed. "Anyway, back straight please. This shouldn't take long at all."

As instructed, Rainbow straightened up, holding still while Rarity worked her magic. Letting her eyes wonder, she took notice of the unicorn's intense focus. Every minute detail was sewn with a swift finesse as she immersed herself in her craft. Sure, all the girly fashion junk never appealed to Rainbow herself. But she couldn't help but admire the fact that Rarity had passion. She also couldn't help but notice that Rarity made some cute faces while she worked.

*Plip...plip*

Rarity blinked as two drops of liquid dripped onto her snout. She glanced up as a few more fell from Dash's undercarriage. Rainbow quickly glanced away.

"Uh...s-sorry about that, Rares." Rainbow said nervously.

"Oh, it's...quite alright, dear." Rarity tried to assure her as she brushed the moisture off. She finished the last stitch and took several hoofsteps back, trying to ignore the fire in her loins.

"Alright, Rainbow. Now just strike a few poses for me so I can make sure everything holds. Perhaps start with the downward dog position?"

With a defeated groan, Rainbow Dash did as she was told, lowering her front half with her exposed ass up in the air. Rarity circled around her a few times. While she was indeed making sure her latest work was structurally sound, she couldn't help but take in the sight of the tomcolt in such an erotic display.

*Squelch*

Rarity's ears perked up and had just barely seen the pegasus' feminine folds give a very audible wink before her tail whipped back down.

"Alright! I'm done! Sorry, Rarity but I've had all I can take."

Rarity sighed, but conceded. "Very well. I really do appreciate all the help you've given me."

"Yeah, sure. Can we pleeaaase get me out of this now?" Rainbow begged. With some quick horn work and her own urgent need to end this as well, Rarity had the pegasus undressed in the blink of an eye. "Awesome, great! Hate to cut and run on ya but, uh, I...I just gotta go see ya!"

Rainbow Dash was nearly out the door on the last word before taking flight. A stunned Rarity sat in silence for several seconds before she realized she was finally alone. She bolted to the door and locked it up, doing the same with the windows and throwing the curtains shut.

"SWEET MERCIFUL CELESTIA!"

The unicorn's cry carried throughout the boutique as she slumped to the floor. Breathing heavily, she looked down between her legs at her feminine juices pooling on the floor.

"Goodness, what kind of a lady am I?" Rarity said as she brought a shaky hoof down on her pussy. "Hah...and over that coltish...brash...hah...f-fragrant..."

She let her eyes flutter closed as she lost herself in thought. Visions of Rainbow Dash bent over, dripping wet, her musk overpowering every other smell in the air. How utterly devine the prismatic mare's holes looked wreathed in the heart shaped window of those undergarments that formed oh so delightfully around those perfectly sculpted blue flanks.

The sounds of Rarity's hoof obscenely playing with her pussy rang out in the quiet boutique. Image after image of Rainbow Dash in her outfits flooded her mind until she couldn't stand it any longer.

"Hnngh. No...no this simply will not do."

Rarity trotted over to a set of drawers on the other side of the room. Her horn lit up and opened the bottom left drawer, revealing a modestly sized glass dildo that she pulled out with haste. Just as she was about to head to her bedroom, Rarity's snout caught the scent of the aromatic wardrobe as she passed it by. She whimpered, staring at the mound, glass phallus floating next to her.

'I...I really shouldn't.' Rarity thought. It would be such an invasion of Rainbow Dash's privacy...and it's horribly deviant! Oh, but it is just me here, now...'

Heart pounding, Rarity rummaged through the pile before pulling up one of the stockings from earlier. It was still damp from Rainbow's heavy sweating. She brought the garment up to her nose ever so slowly, giving it the faintest sniff. The sour smell filled the fashionista's nostrils, and with it withered the last of her resolve.

*SNNNNNNNNFFFFFFF*

The aroma took hold of her body completely, leaving her desperately wanting more. Dropping the sock, she frantically searched through the pile again, until she happened upon the black sodden thong. Her reservations about what she was doing totally eradicated, Rarity shoved the dirty panties into her face, huffing the arousing stench of Rainbow Dash's horny pussy and musky asshole off them.

"Ahhh! Good heaven's, yes!" the unicorn cried passionately. The floating dildo zipped around to her backside. Quickly lining herself up, the glass toy torpedoed forward, burrowing itself into into her burning depths.

"NNGH!"

Landing at the entrance of the Carousel Boutique, Rainbow Dash beat on the locked door.

"Rarity, open up! One of your stupid bows was stuck to my tail!" she shouted. No response. Rainbow growled angrily to herself.

"Grrrr! I don't have time for this! If I don't get home and flick my bean soon I'm gonna lose it."

Doing her best to ignore her aching nethers, Rainbow scanned the outside of the shop until she spotted an open window on the second story.

"Bingo."

The nimble pegasus leaped up and flew right through, landing in an unlit room. Making her way downstairs, she picked up on the sound of grunting coming from the main room. Rainbow chuckled, conjuring up a silly image of Rarity having gotten tangled up in several yards of fabric. That thought was quickly dismissed however when she rounded the corner and saw the sight before her.

There was Rarity. The most prissy pony Rainbow Dash had ever met, on her back in a small mountain of dirty clothes with a glass horsecock drilling her pussy. The most shocking part of the entire display were all the pairs of underwear that Rainbow had worn covering the unicorns face. Loud, shameless huffing could be heard through the layers of fabric as Rarity pleasured herself.

"Rarity?!"

The unicorn nearly jumped out of her skin, shrieking at the top of her lungs and covering herself.

"RAINBOW DASH?!" Rarity panicked as she locked eyes with the pony who's scent she had been masturbating to, slowly walking up to her.

"R-Rainbow, I-I can explain! I-"

Rainbow cut her off. "Really? You're gonna explain how you were about to cream yourself while sniffing a bunch of dirty panties?"

Rarity closed her eyes in defeat. She could feel the shame along with her tears about to overtake her, until she felt herself pushed back onto the mound and something wet slither into her mouth. Her eyes popped open to see their lips pressed together. Rainbow broke the kiss for a moment and looked down at her pervy friend.

"You are sooo lucky I'm horny right now." Rainbow snarled before going back in for seconds.

Rarity couldn't believe her luck, but she wasn't about to look a gift horse in the mouth and threw her hooves around the pegasus on top of her. The two wasted no time grinding into each other as their tongues explored one another's. Every breath they shared was tinged with the powerful aroma of the speedster's musk, driving them to a heated frenzy.

"Hah...heheh...geeze, Rares, I can really smell myself on you. Hngh...Did you dive in as soon as I left or what?"

Rarity winced. "Hnnf...Rainbow darling, please. You make me-ohCelestiarightthere!...you make me sound like a wild dog."

"You really gonna...ngh...try and keep up the prim and proper schtick now?" Rainbow grunted. She quickly got up off Rarity. The poor unicorn thought she had somehow offended her friend, until she laid eyes on the pegasus' dripping wet backside.

"Let's see you try to act all prissy with this on your face!" Rainbow Dash said as she dropped her ass right on Rarity's snout, wriggling her rump into place. "Ngh, How's that? Bet the source is way better than some dirty underwear."

Rarity locked her hooves around Rainbow Dash's flanks and pulled her ass onto her face as hard as possible.

"Woah!"

The fashionista couldn't have wished to be in a more desirable position. Sophistication be damned, Rarity was going to indulge herself in Rainbow's fragrant bouquet as much as she possibly could.

"Down bad for the Dash, eh Rares? Guess even a snooty pony like yourself c-can't...resist...ohmygosh!"

The wildly flailing tongue deep between her folds turned the prideful pegasus into a quivering mess. She would have never guessed that Rarity of all ponies could eat pussy the way she was doing right then. She couldn't help but grind onto her, fucking her friends muzzle without any restraint.

Rarity was totally lost in Rainbow's flesh. She had a divine taste that she could only describe as tangy and tart at the same time, with an ever so slight kick to it. The air she breathed was dominated by the mixture of aroused pussy and sweaty asshole that sent her brain into high gear. Rarity couldn't lie to herself. This was heaven. Only one thing could make it better.

*Slurp*..."Hah...hah...Rainbow, dear? If you'd be...ever so kind?" Rarity pleaded, spreading her legs wide.

Taking the hint, Rainbow Dash laid down on top of Rarity again, this time to her own helping of pussy. Hugging Rarity's bottom half, Rainbow returned the favor and sealed her lips around her friends winking clit. Rarity gasped as Rainbow firmly sucked on her love button. She greedily locked her legs around Rainbow's head as she ramped up her own tongue work. The twitching, dark blue ponut in front of her had been teasing her for far two long. Rarity freed her tongue from Rainbow's quivering snatch and immediately inserted into the donut shaped hole, the ripe anal flavor exploding across her tongue.

Rainbow moaned in pleasure, mouth still full of clit as her tailhole was invaded. She couldn't believe that Rarity was actually sticking her tongue up her asshole. Who even was this mare? Dash wondered. Was this the same pony who would faint from a spot of mud on her coat? She couldn't wonder long, as Rarity's skillful tongue twisted and turned inside of her rectum.

Both mares redoubled their efforts, losing themselves in each other's bodies and racing towards their inevitable climaxes. Rainbow Dash was able to make quick work of Rarity with her unyielding clitoral assault, though Rarity hadn't exactly been putting up a fight. Letting herself go, Rarity felt the rapturous surge overcome her, and blasted her spontaneous lover in her juices with the force of a geyser. She squeezed Rainbow Dash with all her strength as she came, her tongue reaching new depths in her dear friend's asshole.

That was all Dash could take before she too gave the surprisingly capricious unicorn her own helping of hot mare cum.

"NNNGH...HNGGAHH! B-Bucking swallow it!!!"

Rarity slid her mouth down and swallowed as much of the fluids as she could. She coughed, spitting some up back against Dash's already messy holes. The sound of Rarity choking on her squirt only made the pegasus push against her harder. After coming down from the intense orgasm, Rainbow rolled off of Rarity, relishing in her much needed relief.

"Holy cow, Rarity! I had no idea you had such a freaky side!" Dash chuckled, slightly winded.

Rarity sat up, not fully listening to anything Dash was saying.

"Gosh, I can't remember the last time somepony ate me out like that. I still can't believe you stuck your tongue in my bu–"

Rainbow's rambling was halted as Rarity leaned in close and dragged her tongue from her mouth up to her snout. The unicorn smacked her lips, savoring the taste of herself.

That...was a little weird. Granted, everything about that day had been weird, but with the need to get off extinguished, it was a lot more obvious how bizarre it was for Rarity to be acting the way she was.

"Ooookaaay...Uh, this is Rarity I'm talking to, right? Please tell me I didn't just bang a changeling."

Not getting a response fast enough, Rainbow grabbed the cum-drunk unicorn and gave her a good shake.
"HELLO! EQUESTRIA TO RARITY!"

Rarity snapped to her senses and looked at her friend with the same wide eyed stare she had when Dash first caught her. Her eyes teared up, her bottom lip quivered, and then the flood gates opened.

"Ohh Rainbow Da-ash! Can you ever forgive me-ee-ee!" The unicorn sobbed, pulling her bewildered friend into a hug.

Rainbow awkwardly patted her on the back, not exactly used to somepony breaking down crying after sex. But she did her best to comfort her.

"Hey, if this about me finding you going full pervert earlier, don't worry about it. I mean yeah, it was pretty weird to see at first, but I think you've already made up for it."

Rarity sniffled, trying to regain her composure. "I-It's just been so long since I've, been with somepony. I really threw myself into this latest fashion line-up, trying to distract myself. But after watching you model them, and picking up on your...oh good heavens forgive me...your scent as well. Oh Rainbow Dash, darling I simply couldn't help myself!" The distraught unicorn choked back another sob.

"Yo! Rarity! It's cool, WE are cool. I promise, no hard feelings, okay?" Dash said assuredly.

"Y-You, you mean you're not angry with me?"

"Kind of hard to be mad after a sweet nut like that, heh. Boy, imagine the looks on the girls faces if they knew you could eat a-"

"OUT of the question!" Rarity shouted. "No pony can EVER find out I behaved in such a manner. Why I'd be ruined! Reduced to nothing more than a pervert! A shameful harlot!"

"Take it easy! I won't mention it to anypony, you can count on it." Rainbow reassured her. "Buuut...you are kind of a pervert. Heheh...panty sniffer."

"Rainbow Dash!"

The pegasus laughed as she propelled herself into the air. "Sorry Rares! I know you're dirty little secret now. But hey, if you ever want to get up close and personal again, you can stuff that pretty face between my flanks anytime." she said with a wink before heading back upstairs. "But for now, I gotta split."

"Where in Equestria are you going?" Rarity asked. "The front door is that way."

"About that, you should really make sure all your windows are locked if you don't wanna get caught next time. Later! Hahah!" Rainbow cackled before speeding off.

Rarity could have kicked herself for that, but she couldn't complain with how things turned out. She got up and went to the nearby mirror and looked herself over. Her hair was a disaster and her coat was heavily matted with sweat and...other fluids. She looked at the wardrobe pile that lay in disarray, equally as sullied as she was.

"Goodness, what a mess we've made." she said to herself and smiled. "Though I must admit, it certainly was fun making it."
