After a night of drinking, Rarity wakes up with a rather prominent guest in her bed.

Everyone knows Pinkie Pie throws the best parties. The volume goes up, the drinks go down, and everypony enjoys themselves as they let the fun take over. Even Rarity let's her grace and etiquette slide for a time to party with her friends! But after a few too many the night before, she awakes to find a suitor shares her bed. This guest, however, is far more important than even she had expected.

Another short fic. This was more of a crack pairing at the time of writing! A bit saucy, so read with caution!

By the way, the date this was written was before Season 2 had even truly started. You may have to revert to get into that pre-canon-Luna mindset. XD

Last Night at Pinkie Pie's

Birds chirped excitedly outside as morning light shone into the upper level of the boutique. The soft glow stretched across the floor of the room, creeping silently to the large canopy bed on the far side. As the light spread gently across Rarity's face, her eyes fluttered open.

"Oooh, my head..." The first thing she noticed was the spinning, twisting sensation familiar to the morning after drinking. It wasn't quite the pain of a hangover, but was definitely a sign that she had had too much the previous night. The world before her spun around on a misaligned axis as her eyes adjusted to her hazy senses. "Didn't I say something about never drinking again after the last time?" She had, but she had also promised herself that very same thing before, breaking the vow every instance with enough time between.

The second thing she was aware of was hooves around her sides. The heat of another pony burned intimately at her back. "Oh, dear, not again..." She must have taken somepony to bed last night. Again, it wasn't the first time. Though a rare occurrence, she had awoken with stallions before, but never in her own bed. She made a point, even when intoxicated, to be prudent with whom she allowed into her personal chambers. This pony must have been special to wind up here this morning. She tried to remember what had happened the night before, finding it all still a blur.

She gathered what she could about the pony on her other side without turning. The pony had a rather large build. Perhaps she had finally gotten that coy Big Macintosh to throw off his harness collar for a tryst? Still, the mysterious date seemed too thin to be the workhorse, this pony's features more lithe in comparison. As she analyzed more, she noticed the sensation of wings around her as well. A pegasus? That was new. Rainbow Dash flickered briefly in her mind, causing her to squirm. Perish the thought of her being so intoxicated as to take that pony to bed. Dash was a great friend, without question, but she was far too brash for Rarity's preference. And she could only imagine how she would have to explain that to the others later. Besides, to the best of Rarity's knowledge, she didn't have feelings for Dash, none more than she had for any other mare. Hopefully that ruled her out.

The pony behind her stirred slightly. Rarity was wrapped tightly in both wings and hooves, being pulled closely to the unknown pony. Wonderful warmth radiated over her as she was embraced by the heated body. A gentle nibbling began at her withers, working up her neck on the side, tantalizingly hot breath guiding its path. The teeth found her ear at the peak of their ascent, biting teasingly at the base, before a wet, warm tongue traced along its edge. Shivers shot throughout Rarity, the loving play melting her core. Whoever this pony was, she reflected, they had just earned their keep.

Rarity then noticed one last thing in the room. A mannequin she often used to prepare her outfits for the following days sat beside the window, its silhouette darkened by the white glow through the curtains behind it. It was not bare, as it was supposed to be. Around it on the floor sat four hoofshoes, flared in intricate patterns and shimmering. A large collar sat around its neck, with a large gem glistening in the morning rays. Atop the mannequin sat a small tiara, shining in gold. The more she looked, the more the items seemed familiar to her. She knew they weren't her own, though.

Her eyes widened in shock as she recognized the articles. They were royal attire; the regal outfit of Princess Celestia. She shifted her eyes down to look over herself, trying her best to not reveal she was awake. The white wings and forelegs, and the colorful tail over her hind legs confirmed her suspicions. She had bedded the royal Princess of Equestria!

Her heart shook with panic. How had this happened! How did she end up with Princess Celestia! In bed! This can't be right!

She thought hard, trying to remember the night before.

Dusk had just rolled over, the sky darkening as the sun was laid below the horizon. With the colorful party lights beaming in wild patterns over Sugarcube Corner, however, it was almost hard to tell.

It was a special night for everypony in Ponyville. Though Pinkie was known as "Ponyville's Pink Party Pony," this name didn't stick from the small gatherings she occasionally organized with her close friends. Though those events were great, there was one day that truly cemented her title. One huge celebration to rival the Gala. "Party Day."

It had been Pinkie's idea ever since the fiasco at the Grand Galloping Gala a year ago. After their return to Ponyville, Pinkie entered a small slump. What she had always regarded as the best party in all Equestria hadn't been much of a party at all. She seemed so distraught, even taking time off from baking. Finally, the idea came to her. If the Gala wasn't the best party of all, then she would just have to throw one herself. Nopony knows where she got all of the soda or punch, or how she had made so many sweets and snacks in private, or even how she had gotten Vinyl Scratch to DJ on such short notice, but she did. Oh, she did. The huge celebration sprawled over half of Ponyville, taking up Sugarcube Corner, spreading into the Market District, and even into the Town Square a street away. The first year's festivity was so lively that the next day, Mayor Mare, though still tipsy from the party, announced that it would be a regular holiday. Tonight was the second annual Party Day, contending well against the first before it had even started. Bass blasted in heavy, booming notes as Vinyl turned up the volume from her outdoor booth. Large spotlights flashed colors and shapes onto huge screens and into the sky around the bakery. Hundreds of ponies had arrived for the event. Though children weren't prohibited, many parents were cautious of letting them run free in the pulsing crowd of partygoers. Some ponies from out of town had even shown, telling of stories they had heard about Party Day last year.

Rarity had been running slightly later than she had hoped, having stayed behind in her shop to finish out one final gown. She pressed her way through the active crowd of sweaty, lathered ponies raving in the streets, making her way to the shop at the heart of the event.

Pinkie met her at the door, almost as if she predicted the unicorn's arrival. "Rarity! You made it!"

She smiled back to the pink party-master. "I wouldn't miss it for the world, darling. Though, I must say, I didn't expect this kind of a turn out!"

Pinkie was all too excited over the numbers. "I KNOW! Isn't it great! There are some ponies from Manehatten, and some ponies from Fillydelphia, and even some ponies from Canterlot! Canterlot! Guess their silly little Gala wasn't enough, huh?" She giggled in her bubbly excitement, moving aside to let Rarity enter.

Inside, the shop was a bit more calm than the madness in the streets. Ponies found small circles to chat in, some played party games, and even more enjoyed the almost endless snacks and refreshments available.

Rarity looked around the busy store. "You've outdone yourself again this year, Pinkie Pie. Great work!"

"Thanks!" the party pony chimed. "But the best part is getting to spend time with you girls! The others are right this way." She bounced over to a corner of the room, leading the way through the crowd.

Sure enough, Twilight, Applejack, Rainbow Dash, Fluttershy, and even Spike were gathered at a small table. The group greeted the late unicorn, continuing their banter with her now attending.

Not long afterwards, the music outside suddenly ceased, being replaced instead by hushed gasps and expressions of awe. Every pony inside the storefront turned to look as the doors to the bakery opened. In its frame stood the very Princesses of Equestria, Celestia and Luna.

A stillness Rarity wouldn't have imagined possible just a moment before befell the entire setting. No pony dared make a noise.

Celestia laughed softly. "Why'd everypony stop? We came here to enjoy the party!"

Pinkie leapt behind the two royal mares, putting her forehooves around their necks. "You heard 'em, everypony! They're here to PAR-TAY! And that's a royal order!"

Instantly, the party was alive again, bursting with an electric energy.

Rarity racked her mind for more information as to the previous night. How had she ended up with a Princess in her bed!

The mare behind her leaned forward, whispering softly in her ear. "Good morning, my little pony."

Rarity tensed, unsure of how to respond. How should one respond to royalty in a situation like this?

Celestia chuckled. "There's no need to be so nervous, Rarity." She kissed the unicorn on the cheek.

A blush instantly filled Rarity's face at the touch of the soft lips. The mare definitely knew she was awake now. She had to respond. "G-good morning, P-Princess Celestia."

Again the alicorn giggled. "You know you don't have to call me 'Princess.'" She moved her muzzle to beside Rarity's ear, her breath hot against the delicate tissue. In a husky voice, she added, "Unless you want to, that is."

Rarity couldn't fight the sudden tremble that ran through her, born from a mix of fear, nervousness, and sheer desire. 'No!' she thought. 'No, Rarity! This is the Princess, remember! Whatever happened last night, it was obviously some sort of mistake!'

It certainly didn't feel like a mistake. A stray hoof slipped around her, pressing into the coat of her chest, making small circles in the bristled fur. Again, she felt teeth tugging affectionately at her neck, a flick of tongue following each pinch. She tried to protest. Her voice betrayed her, only managing to weakly utter her intents. "P-p-p-prin-c-cess..." she called, finding no other words would follow its lead.

Celestia giggled again, her face nuzzling next to Rarity's own. She was blushing as well, the heat burning like the sun off her cheeks. "Did you like the sunrise, Rarity? I made sure it wasn't shining too brightly for you." The Princess went back to teasing the unicorn's neck with small, loving bites.

Rarity couldn't help but reply to the royal mare's treatment. "It... was beautiful." She felt herself slipping away in the warmth and sensation surrounding her. Soft fur at her back, feathers sensually tickling her sides, and those soft, magical lips working wonders on her neck. Rarity snapped herself away from her senses, falling back into her logical mind. "Princess, did we... last night..."

"Wasn't it wonderful?" the alicorn whispered in her ear.

So they had? "Oh, Celestia..."

The Princess giggled behind her. "Yes?"

Rarity realized too late how her exclamation of frustration failed to carry the same meaning in this situation. As Celestia snuggled closer to her again, the unicorn tried her best to remember how she had ended up with the Princess last night.

The night continued well after the Princesses had arrived. Rarity and her friend had found the company quite entertaining after the initial start of having the royal sisters joining their company. Luna had come out of her shell as the conversations ran on, the group finding more common ground than they had imagined. Even with hazy memory, Rarity recalled how much Luna reminded her of Fluttershy, both in her shyness and girly demeanor.

"It is so good to get out of that stuffy old palace and just have fun!" Princess Celestia spoke in a rather loud voice, taking a sip of fruit punch. "When I heard about this party last year, I was quite disappointed to have missed it. But when I discovered you were throwing another this year, I just had to be here! And of course I had to bring Luna with!"

Luna took a drink of her own cup, also filled with the sugary drink. "You say that like you had to make me show up! I wanted to be here just as much as you did!" She giggled at her older sibling.

As the empty punch cups filled on the table, Rarity found herself a bit parched herself. She excused herself from her friends, walking over to the punch bowl. "Does anypony want a drink while I'm up?"

Princess Celestia quickly quaffed the remaining drink in the cup she held with her magic. She turned to the unicorn. "HAY YEAH!" A soft chuckle rose from all ponies around. None had expected the Princess to be so laid back!

Rarity took the cups by her magic, filling them from the bowl and trotting back towards the table. As she approached, she took a small sip from her own cup. She almost tripped as the sting of alcohol burned in her throat.

Somepony had spiked the punch! "Spiked" wasn't even the right word! It was more liquor than fruit by the taste of it! She immediately knew whose hoof had mixed the concoction. She'd recognize a "Pinkie Pie Special" any day. It also explained the Princesses' behavior quite nicely. Still, Rarity was never the pony to turn down a civil drink or two, especially not at a party. She took another sip as she passed the other to the Princess.

Rarity's recollection was cut off abruptly as a rather adventurous hoof found its way far lower on her body than she had anticipated. A sharp gasp escaped from her, invoking a lustful moan from the alicorn that held her.

"That was some party, wasn't it?" Celestia whispered seductively in Rarity's ear. "And I don't just mean Pinkie's," she concluded with a laugh.

Rarity couldn't even respond, the subtle touch of her bedmate gripping her thoughts like a vice. Her heart again thumped wildly in her chest, caught between feelings of apprehension and desire. The older mare was certainly experienced, hitting just the right spots to make her writhe in ecstasy.

'Rarity! You know this isn't right!' Her thoughts fought her, reminding her of the score. 'This is Princess Celestia! You can't be doing this with Princess Celestia!'

She was right. She reached down, stopping the altruistic hoof with her own. She turned her head, finally looking to the alicorn. She blushed at the sight, having never seen the Princess without her royal jewelry before. She was far more lovely than Rarity had prepared herself for. Perhaps she felt more for mares than she thought.

Finally, she was able to speak. "Prin-" Oh, what was the point of holding formalities by this point? "Celestia, please, we need to discuss las-"

Her words were cut off by the intervention of lips, an intrusive tongue parting her mouth open to coil in slippery motions inside. As much as her mind wanted to fight the sensation, her body couldn't help but follow suit, rolling her own tongue blissfully over the royal pony's in a battle of wetness and warmth. She turned her body in full to the Princess's, pressing her chest tightly against the alicorn's. It was wrong, yes, but it felt so right.

Celestia pulled back from the kiss, a small thread of saliva still connecting their tongues. Her delicate cheeks lit with a blush. "Last night was amazing, Rarity."

"Last night?" Rarity cringed. She couldn't even remember. She couldn't remember how she had ended up with her first mare partner, but more importantly, it was Celestia! How could she not remember that!

The memories were far too disjointed for her to clearly recall much of anything, only coming to her as random images and scenes. She remembered finishing her fifth cup of the volatile punch, chasing it with a wedge of lime and some salt she had taken from the snack table. Her friends cheered her on, each feeling the effects of the beverage. Twilight had let Spike have a small sip, the dragon quickly rejecting the brew. He had finally given up trying to understand what had overcome his friends, running off to play with the Cutie Mark Crusaders. At some point, the punch gave way to undisguised bottles of alcohol. Fluttershy, encouraged by her friends and the drink respectively, had taken a body shot off of Luna's belly, the Princess giggling bashfully the whole time. Rarity remembered having climbed onto the table with Celestia, the two of them singing "Equestria Girls" into bottles they levitated before themselves like microphones. Pinkie made out with two random colts and a filly, which were only the ones Rarity had seen. Knowing how Pinkie gets after a few drinks, there had probably been more. The more she reflected on it, the more Rarity thought the mare may have been Cheerilee. That was about the time Vinyl joined them, letting the music play without her at the booth. There, the memories were even fuzzier. Flashes of mixed drinks and glowsticks. They must have ventured out of the shop and into the seething crowd. She seemed to remember Rainbow Dash breaking open a few glowsticks and coloring her mane and tail appropriately with the liquid light inside. She saw Applejack kissing Caramel, the colt's face red from the sudden and surprising affection. Twilight and Vinyl had made a game of each holding a different drink in their mouths, mixing them with a deep kiss. Hadn't Fluttershy joined in too? Just how much had they drank?!

Celestia lovingly nipped at Rarity's collar. The small pinch was exhilarating, causing the unicorn to arc back into the protective wings around her. The alicorn rolled Rarity onto her back, her larger body resting over the white pony's. Again she kissed the smaller mare, hot breath exchanged between them. Parting slowly, the larger mare began to trail pecked kisses down the unicorn's chest, moving lower with each.

Rarity knew she had to say something, but the words left her. All desire to protest had abandoned her in the wonderful sensations. Finally, as the soft pecking kisses reached the sensitive reaches below her belly, her body reacted without her. She darted out from beneath Celestia, sitting up at the head of the large bed. "Princess?!"

Celestia returned a quizzical glance to the startled pony. "Is there something the matter, Rarity?"

She couldn't deny it anymore. "Princess Celestia, I... I don't remember what happened last night. I had far too much to drink. I don't even remember how we ended up together!" She closed her eyes, bracing herself. Maybe the moon is nice this time of year.

Celestia laughed. "I didn't think you had had that much!" She moved closer to Rarity again, her face brushing the white unicorn's softly. She nibbled on Rarity's ear. "I guess I'll just have to show you what happened."

A war raged inside Rarity. She had always thought of herself as deserving royalty, but this was not at all what she imagined! She was just a fashion designer, not even a Canterlot resident! Perhaps she had just been a one night fling for the Princess? The very thought struck her with a cold, bitter feeling. What if Celestia did love her? Did she love the alicorn in return? Had she felt anything the night before, or was it just the substance taking control? She had never even thought of mares like that! And if she did return the feelings, could she even act on them? This was a Princess! Blueblood was little more than a high noble, but this mare was the pony that acted as the sole ruler of Equestria for the past 1000 years! For every part of Rarity that wanted more, equal forces fought against the desire.

"Rarity," the alicorn asked, moving away from her. "Are you okay? There's something bothering you, isn't there?"

Where could she begin to explain this? Should she, even? There was no clear answer. She just had to go for it. "Princess, just what did we do last night?"

"Do you have to ask?" Celestia responded, a warm blush growing at the edges of her smile.

Rarity had feared that much. "Princess, I-"

"What happened to just calling me 'Celestia?'" the royal mare asked. "You act like I'm going to send you to the moon if you don't!" She laughed again.

The jovial chuckling faded away, Rarity's nervous face providing an unspoken reply. Celestia seemed to put the pieces together. "You... you're scared of me?"

"Nonono!" Rarity quickly responded "It's not that, just..." But that was it. She was scared. She was scared of what she had done, and what the Princess might do. She was scared of the pony she had shared a bed with.

Hurt spread over the alicorn's features. "I... I see." She moved off of the bed, walking to the small collection of golden wear on the mannequin.

Rarity felt an emptiness eating at her inside. What had she just done? "Princess, please..."

"It's all right, Rarity. I understand. You don't want to be with me."

"It's not like that, Princess!"

"Yes, it is," Celestia responded flatly, placing her hooves in the decorative shoes. "I'm a Princess. I'm untouchable." She levitated the large collar over her head, lowering it around her neck. "I'm more familiar with this than you think. After last night, I thought that maybe I had found somepony who could see me, and not a crown." She used her magic to place the golden diadem on her brow. "And, maybe I got too ahead of myself." She turned to Rarity, dressed as the Princess the unicorn had always known. Her eyes beamed of sorrow. "I'm sorry." She turned to walk to the door.

Rarity knew she had made a mistake. A trembling pain tore through her. "Princess, wait!"

The alicorn continued to move to the door.

"Please! Princess, we need to talk!"

The mare never faltered in her exit.

Rarity felt tears biting at her eyes. "Celestia! Stop!"

The Princess stopped mid-step, her hoof placed on the door. She turned to the unicorn. "You... you called me 'Celestia.'"

She had. She hadn't meant it, but she couldn't bear to see the alicorn leave. A warmth fluttered in her heart. There were definitely feelings below the surface for the regal mare, ones far deeper than admiration alone.

"Celestia, please," she begged. "I... I don't remember last night, no. But I know it couldn't have been an accident. Somehow, we ended up in each other's hooves." Her heart continued to beat at a furious pace. "And, maybe I want to remember. Maybe, I do want more. Can we talk about it?"

Celestia smiled warmly. "Well, if you want to know, you made the first move."

"I did?" It wasn't like her to do that. Normally, she played the bait, letting the colts come to her.

Celesta giggled, her face turning red in turn. "You asked me if I wanted to 'make a dress' with you."

Rarity suddenly remembered the final moments of the night. The dispersing crowd, the starry sky above the town. She remembered the emotions that overcame her.

"So, Celestia," the bold unicorn asked, trying her best to mask her drunkenness. "Why didn't you tell us you were a pony who enjoyed her soirées?"

Rarity and the Princess both lied in the field beside Ponyville, staring up at the stars. The party had expanded much further than last year's, the grassy hillside littered with plastic cups and depleted glowsticks.

Celestia laughed, obviously just as tipsy. "Well, the palace life doesn't allow for much freedom like this. Trust me, I can party with the best of them! I have many millennia of experience."

The two gazed at the cosmic play above, the sky speckled with twinkling starlight and the swaths of distant galaxies. It was simply breathtaking.

"Beautiful, isn't it?" Celestia asked. "My sister made all of that. Ponies give me credit for what I do, but how many really appreciate her work?"

Rarity turned her head, looking to the royal pony. "It really is a sight, but-hic!" She hiccuped lightly, blushing and covering her mouth with a hoof before continuing. "But I've always loved the sunrise."

"Oh?" Celestia caught the flirty comment, returning the unicorn's gaze.

"Have you seen my dresses? They are simply divine."

"Other than those at the Gala, I can't say I have."

"Let's go peruse my boutique, shall we? Maybe we'll make a dress ourselves?" She let out a bubbly giggle, moving closer to place a small kiss on Celestia's nose.

The two found their hooves, with only a few drunken stumbles, and walked off towards Carousel Boutique.

The heated memories flushed over the white unicorn, powerful emotions burning in her again. With her inhibition at the time, she had gotten over the royal mare's title, seeing her for the fun pony she was. Before her, Celestia was no different from last night. It was only herself that had changed, sobriety reinstating the status that preceded the alicorn. Looking into those pink eyes, the emotions flooded her again. Princess or no, Rarity knew it was love burning in her.

"Celestia," she began. Using her magic, she lifted the crown from the alicorn's head, levitating it back onto the mannequin. "Please come back to bed, darling. It's far too early still, and I'd love the company."

Celestia chuckled softly. "Of course, my dear." Stepping out of her vestments again, she moved back to the bed, snuggling beside the unicorn.

Wrapping her large wings again around the pony, she spoke. "If you think it was awkward for you, just imagine your friends' reaction today."

Rarity cuddled against the mare's neck, her hooves, gently rubbing into the fur. "Whatever do you mean?"

"Well," Celestia explained, "Luna went home with Twilight last night. And so did Fluttershy." Both ponies laughed, letting their imaginations play with the fun situation playing out just down the street.

"Celestia?"

"Hmm?"

"Thank you for coming back."

"Thank you for letting me."

At last, Rarity let her eyes close, falling peacefully asleep in the hold of her partner.
