A gratuitous clopfic, if you haven't noticed.

Chapter 1

“This is gonna be so cool.” Rainbow Dash rubbed her hands together.

“Calm down, Rainbow.” Twilight Sparkle gently chided her friend. “This isn't a new Wonderbolt trick-- this is a big responsibility you're volunteering for.”

“Big just means awesome.” Rainbow Dash flapped her wings and swung around to fly in front of her nerdy-yet-regal friend, hovering backwards as Twilight walked through the halls of Canterlot Palace. With the sun's setting, the activity of the palace had begun to die down-- one by one, the lights in each chamber winked out, save for the silvery light still shining from Twilight and Rainbow's destination, a room at the top of a tall tower.

Princess Luna's chambers.

“Just make sure you're not biting off more than you can chew.” Twilight said. “I mean, the dream realm is a strange place-- Princess Luna has centuries of experience watching over it. Being the guardian of Equestria's collective subconscious isn't exactly something you can call 'dibs' on.”

“Except I totally called dibs on it.”

Twilight sighed, rubbed at the bridge of her nose. “Just ... be careful, okay? I mean, I'm going to be there to help you-- just like you'll be there to help me, but this could be one of the most dangerous things we've ever done. Which is saying something.”

“Oh man you just make it sound even sweeter.”

Twilight rolled her eyes. “Sometimes I wonder why I even bother ... “

As the two spoke, they climbed the spiral staircase up to Princess Luna's private chambers, and came to a halt in front of a heavy oaken door, emblazoned with a silver-white crescent-moon logo. Before Twilight could even mention the word 'decorum,' Rainbow Dash rapped her knuckles on the wooden door. Loudly.

“Hello? Princess Luna? We're here for the Dream Warrior lessons!”

Twilight elbowed her friend. “There's no such thing as a Dream Warri--”

“Enter.” The Princess of the Night's voice boomed from everywhere and nowhere, all at once, and the door creaked open.

Inside, Luna's chambers were a study of varnished oak and purple velvet. The domed ceiling was painted with constellations, each star glowing faintly with magic (and in its proper place for the season, Twilight couldn't help but notice). Princess Luna herself sat in a high-backed chair, waiting.

Rainbow and Twilight stopped at the threshhold, and stared. As while the both of them were used to being underdressed for certain formal occasions (an inevitable side effect of being good friends with Rarity), this was likely the first time either of them realized they were technically over-dressed.

Princess Luna had forgone her formal gowns or formidable battle-armor for something decidedly more casual; a silken dressing-robe, dyed night-black. The thin silk draped over Luna's body, more than hinting at her body beneath. A loosely knotted sash around her waist kept the robe closed-- but barely –Luna's deep blue bust pressed at the silk, shifting with each of her graceful movements. In comparison, Rainbow's athlesiure-casual-chic tank top and sweatpants were downright formal, while Twilight's skirt, blouse, and sweatervest bordered on black-tie.

“Sorry!” Twilight's muzzle flushed pink. “Did we get here too early? We got here too early, didn't we? You didn't even have time to get dressed yet! Hah ha! How funny! We'll just go now, try this again later-- dammit stop staring Rainbow Dash.” Twilight caught her friend by the elbow and turned for the door.

“You are not intruding, nor are you early. Stay, friends. Please.” Luna's horn glowed, and two more chairs floated over from the edge of the room. “We have much to discuss.”

“Damn right we do!” Rainbow Dash pulled her arm free of Twilight's gentle grasp and plopped down into one of the chairs. “Don't mind Twilight-- she's just all nervous about this whole 'dream realm' thing because she hasn't read like every book ever about it.”

“That's because there aren't any books written about the dream realm.” Twilight huffed as she sat down in the other chair. “... have you ever considered fixing that, Luna? I'd be happy to work as your editor--”

“Believe it or not, Twilight, there are some things that should not be put to paper.” Luna's horn glowed again as she levitated a bottle of wine and three goblets over from a far shelf. She poured out three glasses, then passed two of them onto Rainbow and Twilight without asking. “Some things must be seen-- must be experienced –firsthand.” She sipped at her red wine, then leaned back in her chair, shifting her wings slightly. “Very few ponies have ventured into the realm of dreams-- to do so unprepared is to invite disaster. There is no dishonor in stepping back now, should you wish to spare yourself the--”

“We're in!” Rainbow Dash blurted, nearly spilling her wine in the process. “Or, uh, I'm in, at least.” She peered over at Twilight, shit-eating grin shining in the dim light of Luna's chambers. “Seriously every time you guys get all 'ooo this is spooky' it just makes things sound so much cooler.”

“Your enthusiasm is admirable, Rainbow, I pray your resolve is just as strong.”

“My everything is strong, baby!” Rainbow Dash flexed a toned bicep. “Now let's do this thing!”

“What she means is, 'let's take the first baby steps into a new and dangerous but hopefully educational journey.'” Twilight said with a forced grin.

“So where do we start?” Rainbow Dash put her hands on her knees and leaned forward, wings fidgeting in anticipation. “Like, do we get all jacked up on shrooms and hallucinate a dream quest? Do we learn secret martial arts that help us meditate and also punch people with our brains? Do we go, like ... I dunno, fight a ghost or something?”

“First, we sleep.” Luna sipped at her wine.

“That ... does make sense for dreaming.” Twilight mused.

“Follow me.” Luna stood in a whisper of dark silk, and led further into her chambers, hips and tail gently swaying with each step.

“Jeez, look at the wingspan on her.” Rainbow Dash murmured, biting at her lower lip.

“Rainbow.” Twilight scolded her friend, hoping Luna didn't hear. The two followed Luna deeper into her chambers, ducking through a silken curtain (black, of course) to what was obviously the royal bedchamber. A large, round bed, piled high with pillows and blankets dominated the center of the room.

“You may disrobe and make yourselves comfortable.” Luna said. “Once you are properly asleep, we may begin.”

“Uh.” Twilight blinked again. “There's just the one bed.”

“And?”

“Isn't that a little, um ... awkward?”

“It is the safest way. The closer our corporeal bodies are, the more protection I shall be able to grant you in the dream realm.”

“That ... makes sense.” Twilight said. “If I'd known, I would've brought my pajamas.” Twilight gave a nervous laugh.

“If you insist, you may find sleeping garments in the wardrobe.” Luna said.

“Pssh, who needs 'em?” Rainbow Dash peeled out of her tanktop, then shucked her shoes and sneakers next, leaving her in bra and panties, both in plain gray. Rainbow Dash showed no shame at displaying her lean, toned form-- then again, Rainbow Dash rarely showed shame for anything.

“I just want to be, uh, appropriate?” Twilight said. She walked over to Luna's wardrobe and opened it up, revealing a Princess' worth of lacy sleepwear. Twilight carefully rifled through the hanging garments and tried not to think too hard about the ones made mostly from straps and transparent lace. She finally picked out the most conservative thing she could find; a long nightgown. Keeping her back to Luna and Rainbow for propriety's sake, Twilight slipped out of her skirt and blouse-- as an afterthought, she undid her bra as well. She never could sleep with one on, especially since her ascension to princess-hood had given her a ... boost, proportionally.

Twilight slipped the nightgown over her head, fussing briefly with the vents in the back to let her wings stretch out freely. Tailored for the taller Luna, the nightgown covered Twilight from neck to ankles, and the sleeves stretched two or three inches past Twilight's fingertips. It could have almost been conservative ... were it not for the way the smooth satin clung to Twilight's body, covering all, but concealing little. Even the points of Twilight's nipples poked out-- because of the cold, Twilight told herself. It was too late to change again now-- not to mention most of Luna's other nightwear looked even more scandalous.

And so, Twilight turned around, hoping Luna's bedroom was too dark for either of her friends to get too scandalous a look at her. Not that it particularly mattered-- Rainbow Dash was in just her underwear, and as Luna stretched out on the bed, her robe parted to reveal even more of her goddess' figure-- one dark-hued nipple had escaped its covering, almost taunting Twilight.

“So ... “ Twilight sat down on the far edge of the bed. “Now we just ... sleep?”

Luna nodded. “Perchance to dream.”

“Doesn't everypony die at the end of that play?” Twilight said.

“Worry not, Twilight. I shall be watching over you. You do trust me, yes?”

“Of course.”

“Then rest, my friends, and prepare yourself for a journey unlike any you've ever experienced.”

“Uuuugh, how are we supposed to sleep when I'm all hyped up from everything being so mysterious and rad?” Rainbow Dash flopped back onto a pile of pillows beside Luna and stared up at the ceiling.

“I can help, if you'll let me?” Luna said.

“If it gets us to the trippy dreamworld faster, do whatever you want!” Rainbow Dash said.

“Very well.” Luna's horn glowed again, and she placed a gentle hand upon Rainbow's forehead. “Sleep well.” Immediately, Rainbow Dash closed her eyes and started to snore.

“Starswirl's Slumber-Touch.” Twilight held a hand up to her mouth. “I thought that spell had been lost?”

“Perhaps it was. But I can teach it to you, if you would like?”

“You'd really do that?”

“Of course-- but later. Now, you have a different lesson to learn. Are you ready?”

“I ... I think so.” Twilight nodded.

Luna smiled, then leaned forward to cast the same spell on Twilight. A wave of peaceful fatigue washed over Twilight, and she felt her body gently give way to sleep. Still sitting, she began to topple over-- the last thing Twilight remembered was the feel of Luna's warm, strong hands wrapping around her as Twilight rested her cheek against something warm and soft.

Chapter 2

Twilight opened her eyes to infinity.

The vast darkness stretched out in front of her, lit by countless stars, faintly twinkling from light-years away. Twilight searched for stars or constellations she could recognize in order to get her bearings, but she soon realized the stars matched no pattern she was familiar with.

She turned around to get her bearings, and found herself standing on a winding brick path, impossibly suspended in the middle of the void. Plain white doors, each one identical to the next, were spaced out along the sides of the road, leading seemingly to nowhere.

About half a dozen doors down, Twilight spotted Luna and Rainbow Dash-- and it took her brain a moment to register that both of them were stark naked. As one would expect, Princess Luna was the more impressive of the two, taller, bustier, and generally more imposing than the scrappy pegasus. She stood as perfectly as a classical statue, utterly confident in her nudity. Despite herself, Twilight stared, taking it all in: long legs, a toned midriff, heavy breasts capped with midnight-dark nipples. While Luna's hair and tail still floated with their starry weightlessness, she had no hair between her legs-- Twilight wondered if it was a grooming decision or some side-effect of long-term princess-hood.

In contrast, Rainbow Dash was shorter and slimmer-- but no less enticing. Countless hours of practice and exercise had honed her body, but there was yet still a hint of softness to be had in the pegasus' perky, upturned tits.

Twilight realized she was staring.

Twilight then realized she was naked too.

“Twilight!” Luna raised a hand in greeting. “Welcome to the realm of dreams.”

“Did ... something go wrong?” Twilight fidgeted beneath her friends' gaze. Her hands began to move to cover herself, but Twilight thought the better of it. Not like they hadn't already gotten an eyeful. “Like ... did we, uh ... leave something behind?”

“Ah.” Princess Luna walked over to Twilight, and placed a gentle hand on her shoulder. “I apologize-- I should have warned you. The dream realm is a place of the mind, and the mind alone. You can dream-- but your garments cannot.”

“That ... makes a surprising amount of sense.” Twilight admitted.

“It is the first of the dream realm's many challenges, to be laid bare-- both literally, and figuratively.”

“Oh.” Twilight said.

“If you wish, you may leave now. For things are likely to get more ... intimate, as they progress. You will see some ponies' deepest, most primal desires, the things that they mention to no one in the waking world. Unrequited love. Unbridled passion. Uninhibited debauchery.”

“Pssh, no big deal.” Rainbow Dash chimed in as she flapped over to the two princesses. “It's just like the locker room, right? And everypony else is asleep so it's not like they can see my butt anyway. Their loss.” Rainbow Dash hiked her tail up and wiggled her rump.

“So, uh, anyway!” Twilight looked away from her naked friends and down the pathway. “Let me guess-- each one of these doors leads into somepony's dreams?”

“Very astute.” Luna nodded.

“But ... they all look the same. How do we know whose dream we're entering?”

“It is something you shall learn, in time. Here, look--” Luna turned to the nearest door and ran her fingers over the white-painted wood. “There are faint differences, if you know what to look for. Here, see the different pattern carved around the moulding?” Luna said.

Twilight leaned in closer for a better look, her bare side brushing against Luna's warm body-- neither Princess moved away from the inadvertent contact. “It's a more ... angular pattern? Interesting.”

“So whose dream-brain is it?” Rainbow Dash asked.

“Someone who is quite close to you.” Luna placed her hand on the brass doorknob. “I believe it should be the best place for you two to start.”

“So what are we supposed to do in there?” Rainbow Dash said.

Princess Luna placed a hand on the door and closed her eyes, meditating. A faint shiver passed through her body, and she opened her eyes. “You shall learn. It may be challenging, but I assure you, it is not dangerous. Are you ready, friends? Or would you like to wake up?”

“Wake up? But we just got started!” Rainbow Dash squeaked.

“If you think this is the best place to start ... “ Twilight nodded.

“Very well, then.”

Luna opened the door.

Twilight walked into a locker room.

Kind of.

She didn't register walking through the door-- rather, things just changed around her in a single instant. The dark night sky vanished, leaving her in a large chamber of white tile and blue lockers. Smells of sweat and soap battled for olfactory supremacy in the warm, steam-heavy air. Twilight looked over her shoulder-- the white door was gone, as was Princess Luna. Rainbow Dash was still there at least, in all her bare blue glory.

“What was that about locker rooms again?” Twilight said to Rainbow Dash.

“Told you it's not so bad!” Rainbow Dash winked at her friend, then reached back to give Twilight a playful slap on the ass.

“Hey!” Twilight squeaked, and rubbed at her faintly stinging cheek. “Careful!”

Rainbow Dash just laughed, and headed deeper into the locker room.

“Rainbow!” Twilight huffed, and followed her around a bank of empty lockers. “We should stick together, just in case--”

“Oh, relax!” Rainbow Dash shook her head. “You heard Princess Luna-- there's nothing dangerous in here. We just need to learn some stuff! And you're really good at that! Here, I bet we're really in like, some buckball coach's mind, and they can teach us some really cool moves!”

“I don't even play buckball.”

“But Pinkie Pie does!” Rainbow Dash said. And, sure enough, there was their pink-hued friend, standing at the end of a bank of lockers. She ruffled her hair with a white towel-- but was otherwise nude. With Pinkie's back turned, Twilight and Rainbow had a perfect look at their friends' broad, curvacious rump, barely covered by her hanging tail. Twilight briefly wondered if Pinkie Pie had started exploring the dream realm on her own-- if any of her friends could do it without any explanation, Pinkie could.

The party pony's ears perked. “Oh, hi guys! I was hoping you'd show up. Take a look at this!” And with that, Pinkie Pie tossed her towel aside (with a near audible 'flooph' of her curly hair bursting free) and turned around. Voluptuous to a 'v,' Pinkie was blessed with an ample chest, ample hips, and ... ample everything else, honestly. And yet, that softness was laid out in just the right places and proportions that even Pinkie's slightly pudged belly was a study in feminine curvaceousness.

That is, except for her cock.

That was new.

The thick member flopped lewdly between Pinkie's legs, accompanied by a heavy set of balls at the base. She soon wrapped pink fingers around the member and began to stroke it, showing off for her friends. “Isn't this neat?” She said, and winked.

Twilight gasped-- and then looked over at Rainbow Dash, who watched Pinkie masturbate with rapt attention.

“Y-yeah.” The Pegasus said, the blue of her cheeks giving way to a scarlet red.

“Wanna closer look?” Pinkie winked.

“Yeah.” Rainbow Dash nodded-- and without prompting, she sank to her knees on the tiled floor. She rubbed the stiffening member along her cheek, and inhaled deeply, savoring the smell of Pinkie's incongruous malehood.

“Rainbow!” Twilight blurted. “What are you doing?”

“It's pretty obvious, isn't it?” Pinkie Pie gently ran fingers through Rainbow's multicolored hair. Rainbow herself couldn't answer, not as she took the thick, dark-skinned cock between her lips and began to suckle at it. Pinkie practically purred, and gave a wiggle that set her large tits to jiggling. “And she's good at it.”

Rainbow Dash murmured a vague affirmative around Pinkie's cock, and began bobbing up and down, making lewd, wet noises with each pass of her lips. The pegasus widened her knees and hiked her tail, letting Twilight see the way Rainbow Dash reached down to her own folds, insistently touching herself.

Twilight stared, then took a step back, unsure of what to do while presented with such a wanton display-- but her retreat came short as she felt herself bump into someone. Someone warm. Soft. Feathery. ... and naked.

“Oh, I'm sorry.” Fluttershy said. “I should have looked where I was going.”

Twilight turned-- and sure enough, there was her other pink-haired friend, just as naked as everyone else. Where Rainbow was lean and toned, and where Pinkie was soft and curvy, Fluttershy's body served as a balance between the two-- tall and willowy, albeit with heavy, teardrop-shaped breasts just a little smaller than Pinkie Pie's-- though the erect cock jutting out from between her legs was bigger.

“Were you waiting your turn?” Fluttershy bit her lower lip as she watched Rainbow Dash suck at Pinkie's cock.

“Um. No?” Twilight said.

“Oh, okay. I didn't want to be rude.” And with that, Fluttershy walked past Twilight and stood beside Pinkie Pie. Without prompting, Rainbow Dash pulled away from Pinkie and immediately took Fluttershy into her muzzle, letting out a lusty, needy moan as she did so.

Fluttershy flared her wings, crying out in pleasure as Rainbow Dash so eagerly worshipped her cock. She soon started working her hips back and forth, fucking Rainbow's mouth hard and deep enough that soon her balls began to bop Rainbow on the chin with each thrust. Fluttershy's breaths grew shorter and higher pitched as she eagerly used her friend's mouth-- only for Pinkie Pie to squeeze in behind her, grab her breasts, and pull her away from Rainbow's muzzle.

“Slow down, girl!” Pinkie Pie said with a giggle. “Dashie's got more than just a mouth, you know!”

“Oh. Right. Sorry. I forgot.”

“Mmmm. I would too, if Dashie was sucking me off.” Pinkie Pie winked. “Now c'mon, let's get her on a bench!”

Rainbow Dash didn't resist as Pinkie and Fluttershy took her by either arm and tugged her up to her feet. The two be-cocked ponies shared a few giggle-filled whispers-- at which point Fluttershy laid down on one of the wooden changing benches in front of the lockers. Pinkie in turn guided Rainbow to straddle her-- though not before she reached down to toy with Rainbow's lower lips.

“Mmmm. She's ready!” Pinkie said in the exact tone she used to make baking announcements.

Rainbow Dash braced her hands on Fluttershy's shoulders, then lowered herself onto her friend's stiff cock. The blue pegasus moaned, shuddered, nearly climaxing right then at the feel of the hard, warm cock inside of her. Fluttershy grabbed hold of Rainbow's hips and thrust upward, eliciting another squeak of pleasure from her. Before long, Rainbow Dash bounced on Fluttershy's cock, her moans of pleasure echoing off the tile walls of the locker room.

“Wow. Look at her go!” Pinkie Pie sidled up beside Twilight and kissed her on the cheek. “Giving you any ideas?” She said with a waggle of her eyebrows.

“I ... don't know?” Twilight said.

“Oh, okay!” Pinkie Pie nodded. “You can just watch for now, if you like! Or if you wanna do more, just ask!” And with a playful giggle, Pinkie stepped away from Twilight and opened up a locker to pull out a small bottle of clear liquid with LUBE written clearly on the label.

Pinkie Pie drizzled a hearty dose of the slick jelly onto her still-hard cock and worked it up and down with a few jerking-off motions before she stepped up behind Rainbow Dash. “Oh Dashie ... “ she said, licking her lips. “There room for one more?”

Rainbow's eyes went wide as she looked over her shoulder at Pinkie-- and in such a lusty state, she could do little but nod. Pinkie Pie just grinned, then took hold of Rainbow's tail, pulling it upwards-- all the better for her to lean in and push her cock against the ring of Rainbow's ass. Even with the generous amount of lube, it was a tough fit-- at first. Pinkie Pie soon started working her cock in and out of Dash's ass, even as Fluttershy pounded her pussy. A loose rythmn began to develop between the three of them-- or, more accurately, between Pinkie and Fluttershy. Wedged between her friends, there was little Rainbow Dash could do but lay over Fluttershy and take an eager fucking in both of her holes. Rainbow nearly screamed in pleasure, mouth hanging open, practically drooling in ecstasy as her body shook with an orgasm. Then another. Then another still, each peaked climax building on the next.

With surprising strength, Fluttershy sat up, then rolled to the side-- Pinkie Pie just let out a cheery “Whee!” as she fell the short distance to the floor, somehow managing to keep herself from flopping out of Rainbow's ass. Positions now reversed, with Fluttershy now on top of the pile, the pink haired pony started fucking Rainbow even harder than Pinkie Pie did-- until she finally slid herself out of Rainbow's pussy, taking hold of her own cock. Fluttershy huffed out another lusty breath, then came, spraying Rainbow Dash and Pinkie Pie both with spurt after spurt of her white seed.

Twilight Sparkle stepped back so she wouldn't step in it.

The other three ponies kept at it, completely ignoring Twilight. The purple princess of friendship shivered, feeling her own body grow hotter just by watching the display. It'd be so easy to just step in and--

--no.

Twilight shook her head. “Luna sent us here to learn.” She nodded to herself, resolute. Even if Rainbow Dash seemed to be learning an entirely different lesson. “Okay, so-- first thing –whose dream is this?” She thought aloud (even if the moans, sighs, and giggles from the trio in front of her drowned her out).

“There you are, Rainbow Dash!” A stern, authoratative tone cut through the locker room, followed by the shrill of a gym whistle. Immediately, Pinkie Pie, Fluttershy, and Rainbow Dash de-tangled themselves from each other and got to their feet, standing at attention despite their naked, sticky and sweaty state.

Twilight turned to the source of the voice-- and sure enough, there was Commander Spitfire ... albeit in decidedly non-regulation attire. At least, if aviator sunglasses, a gym whistle, and an unzipped bomber jacket could be considered 'attire' in the first place.

Spitfire stalked past Twilight like she wasn't even there, then stood in front of Rainbow Dash, glaring. “I've been looking for you, Wonderbolt! Should've known I'd find you like this. It's a lucky thing, too-- 'cause you've had this coming for a long time, now ... “

“Had what coming?” Rainbow Dash asked, blinking.

“This!” Commander Spitfire pounded a nearby locker with her fist, and the door creaked open, revealing a tall trophy wrought out of brass and marble. A small but intricately detailed statue of a nude pony capped the trophy, while the plaque at the base had three simple words engraved on it.

BEST AT SEX.

“I knew it!” Rainbow Dash cheered as Spitfire handed her the trophy. “It's a honor! But honestly, Commander, this was a team effort!” She draped her arms over Fluttershy and Pinkie's shoulders, pulling the two in for a hug.

“Yay.” Fluttershy said.

“Let's celebrate!” Pinkie Pie said, and soon enough the threesome became a foursome as Commander Spitfire stepped in.

Twilight stared. “Guess that explains whose dream this is ... “ she sighed.

And then she woke up.

Chapter 3

Twilight Sparkle woke up to chaos.

Given her experience as the Element of Magic and multiple-time savior of Equestria, this was to be expected. The specific nature of the chaos, however, wasn't. A random monster attack or an unannounced visit from some foreign dignitary-- those were the sort of problems Twilight had learned how to wake up to. The sorts of things she knew how to deal with.

Instead, she woke up to an uncontrollably horny pegasus.

Rainbow Dash's mouth hung open, and her eyes had an unfocused, glassy look to them. She panted and moaned, tangling herself in Luna's silken sheets. Luna herself grappled with Rainbow Dash, trying to keep her still. In the tussle, both Luna's robe and Rainbow's underwear had gotten pushed aside, giving Twilight an even more scandalous view than when she'd seen their naked dream-selves before.

“Help me, Twilight!” Luna said. “Your friend is in grave danger!”

“What? How?” Twilight sat up, blinking the sleep from her eyes.

“I was afraid this would happen. Your friend is fearless-- but she's still a mortal pony. She lacks the magical robustness of a Princess. Visiting her own dream has thrown her astral form and her physical body out of alignment. If we do not do something quickly, she could be driven mad.”

“Then what do we do?” Twilight immediately started running through options in her head. “We could perform a silver-thread spell, and--”

“There's no time!” Luna's robe fell open as she wrestled with Rainbow Dash. “The quickest way to help her is to align her physical body with the same sort of sensations she was experiencing within the dream—”

Twilight's cheeks flushed red again. “But she was--”

“Indeed!” Luna said. “In order to save Rainbow Dash, she needs to have an orgasm. Now, hold her!” Luna pushed Rainbow Dash into Twilight's arms.

Twilight squeaked in dismay, but wrapped her arms around her friend's toned, warm belly nonetheless. Before the Princess of Friendship could ask what to do next, Luna rolled onto her belly, sliding up between Rainbow's haphazardly spread legs. Luna tore Rainbow's sodden panties away with barely any effort at all, and the musky scent of her arousal filled the bedchamber.

With no hesitation, Luna opened her mouth and dragged her tongue up the length of Rainbow's dripping pussy. The pegasus moaned lustily, leaning back into Twilight's embrace. Before long, Rainbow Dash's urgent, unconscious writhing began to pick up a rhythm of its own, matching Luna's attention to her pussy.

Twilight thought about asking Luna for more direction-- but decided against it, as her mouth was ... occupied. And so, Twilight just held onto her friend, as if she could drag Rainbow's consciousness back through the warmth of her touch.

Rainbow's body was very, very warm.

Twilight's fingers splayed over Rainbow's belly, tracing over the taut lines of her exercise-sculpted abdomen, circling around the divot of her navel. How many times had she seen Rainbow showing off in her workout gear or some skintight flight suit, and wondered what it would be like to touch her? To feel the pulse of her heartbeat? To--

Rainbow Dash kissed Twilight.

Twilight made another surprised whimper-- where Rainbow's body was primarily tense muscle, her lips were nothing but soft, the kind of softness that she could just lose herself in savoring as she tasted her friend's lips, the tip of her tongue. Faintly, Twilight registered the wet, lewd sounds coming from between Rainbow's legs as Luna ate the pegasus' dripping pussy, but that was somehow thousands of miles away from the loveliness of Rainbow's lips. Somewhere along the line Twilight slid a hand up beneath Rainbow's tank-top to palm her perky breast and tease over an achingly stiff nipple.

Rainbow Dash came.

It was a subtle thing, at least in comparison to the debauched fucking Twilight had witnessed in the dream. Rainbow broke her kiss with Twilight and let out a high-pitched moan, her whole body trembling against Twilight's.

Rainbow bucked her hips, then shivered from ears to tailtip, finally relaxing so she could pant and stare up at the canopy of Luna's bed. Luna herself sat up, not bothering to close her robe, the dark silk serving to only frame and highlight her goddess' figure. Twilight stared, if for a moment, noting the way the other Princess' dark nipples stood in proud arousal.

“Uh.” Twilight tore her eyes from Luna's tits. “Did it work?”

“Whoa.” Rainbow Dash kept staring upwards, and reached back to run her fingers through Twilight's mussed hair. “That was awesome.”

“Nevermind.” Twilight said.

In a testament to her endurance, Rainbow Dash sat up, finally moving under her own power. She fluttered her wings a little, stretching them out after having pressed them against Twilight's chest in the embrace. “Oh, wait-- hold on, am I still dream-- ow!” Rainbow Dash rubbed at the inside of her thigh where Luna had pinched her. She glared for a moment at the prim, half-nude princess, and then laughed. “Alright, alright, I get it.”

“So, uh, that's it?” Twilight crossed her arms over her chest-- despite being the most covered of the three ponies on the bed, she could already feel her own nipples pressing against the soft silk fabric. “Rainbow's back to normal now, right?”

“As 'normal' as one would expect.” Luna said.

“Whoa, was that a joke? From the big scary night princess?” Rainbow Dash said. “Are you sure this isn't really a dre-- ow!” Despite the second pinch, Dash squealed out a giggle, and then rolled out of Luna's reach. Rainbow Dash flapped her wings and launched herself into the air, flying a lazy circle over Luna's bed. “But seriously--” Rainbow Dash wet her lips as she looked down at the two princesses on the bed. “That was great. I haven't come that hard in ... like, ever. Want me to do you guys next?” She rubbed her hands together in lusty anticipation.

“I'm good!” Twilight said, averting her eyes from Rainbow Dash, even if the pegasus didn't mind showing off in the slightest. “And since that whole thing was kind of a fiasco I guess we should give up and never talk about it ever again okay bye!”

And with that, Twilight activated an emergency teleport spell, disappearing in a burst of purple light.

Safely barricaded in her guest suite within Canterlot Castle, Twilight took a (long, cold) shower. She slipped out and dried herself off before her lips started turning blue, but the frigid water did its job in dispelling thoughts of Rainbow Dash writhing in her arms lost in the throes of lust, or Princess Luna standing proudly, imperiously nude, as if no mere mortal garment was worthy of her--

The frigid water almost did its job.

Twilight soon dressed in something conservative, something proper. A long skirt, a plain blouse, a tweed jacket. She pinned her hair back in a decidedly un-enticing bun and held it in place with a spare pencil. As she looked herself over in the mirror, lit by the morning sun pouring in through the window, Twilight nodded at her reflection in approval. All she was missing was a pair of glasses to complete the 'spinster librarian' look, which was perfect. Nobody thought indecent thoughts about librarians. Not even if someone returned some books late and didn't have the bits to cover the fine so the librarian would have to find some other means of restitution--

Twilight started thinking about a second shower.

But before she could subject herself to near-hypothermia again, Rainbow Dash showed up. Dressed, thankfully-- even if her plain grey sweatpants and baggy buckball jersey hung off her form in far too interesting a manner. She carried a long, flat box in one hand, and a cardboard cup-holder in the other, which in turn had two tall paper cups inside.

“Hi Twilight!” Rainbow Dash said, cheery. “Want some breakfast?”

“How did you get in? I placed a level three force-ward on the door!”

“You left the window open. Donut?” Rainbow Dash set the box down on Twilight's desk and opened it up to reveal a dozen different kinds of iced deliciousness.

Twilight's stomach growled, as one base instinct went to overtake another. She scooped up a cup of coffee and a chocolate-glazed donut and scarfed it down, chasing it with a sip of sweet vanilla latte. The piping-hot coffee overtook Twilight's self-imposed chilliness, and Twilight let out a contented, caffeinated sigh.

“Thank you, Rainbow.” Twilight said, and primly wiped her fingertips off on a napkin. “I guess I forgot how hungry I was.”

“Just like I thought.” Rainbow Dash said. “You always do that whenever you get all, uh, eggheady.”

“I ... do, don't I? It's just so easy to ... forget about little things like that when you're, um. Distracted.” Twilight picked up a glazed donut and started nibbling.

“So yeah. I just wanted to check on you after last night.”

Twilight swallowed, forced a grin. “Eheh. Right. I should honestly be checking on you, Rainbow. I mean, we looked into your deepest desires and--”

“--it was awesome, wasn't it?”

“You're ... not embarassed?”

“I mean, no? I figure everypony's got weird horny dreams, right?”

“But ... Fluttershy and Pinkie Pie were there.”

“They usually are.”

“They are?”

“Yup! I mean, I love my friends, and I love dick, so when you put them together--”

“So have you ever ... been with either of them? For real?”

“Nah.” Rainbow's voice carried the barest hint of regret. “Didn't want to make things weird, you know?”

“And me seeing your explicitly sexual fantasies isn't?”

“When you put it that way it is. Which is why I'm trying to make it not weird. With donuts.”

“These are good donuts.”

“Right?”

Rainbow Dash sat down on the edge of Twilight's desk and took a sip of her own coffee. “Aren't you always saying that friends need to talk their problems over and stuff? 'cause, like, I want you to know that it's totally cool that you saw me naked inside of my own brain.”

“Let me guess-- it's 'cause you like showing off?”

“It's 'cause I like showing off and I trust you, Twilight.”

“Thanks.” Twilight smiled. Sighed. “I appreciate that. But it's not the sex dream-- or, well ... it's not just the sex dream. What you-- what we did was dangerous. I ... might be able to handle it, because I'm a princess, but I couldn't live with myself if anything happened to you--”

“Which is why we should do it together!” Rainbow Dash paused, and then added on. “The dream world stuff, I mean. So long as you're there to watch my back, I know we'll be fine. And the whole part where you go 'it's dangerous!' just makes me wanna do more of it.”

“Got a point there.” Twilight said.

“Look, tell you what. Before you give up on the whole 'Magic Dream Princess' thing, let's try one more time, okay? And if it goes bad the second time I'll give it up and stick to being awesome in the awake world.”

“I ... I suppose it's only fair to give it a shot.”

“Great!” Rainbow Dash hopped into the air once again, beaming. “'cause it's also only fair that if you got to look into my head, I get to hang around inside of yours next!”

Chapter 4

That night, Twilight and Rainbow Dash returned to Princess Luna's tower. They'd come prepared-- though their definitions of 'preparation' were quite different. Twilight Sparkle made it a point to bring a set of shapelessly comfy flannel pajamas to sleep in. Rainbow Dash, in the meanwhile, simply started peeling out of her clothes as soon as they walked into Luna's bedchamber. Stark naked, the blue pegasus clasped her hands together behind her back and gave an arching, feline stretch that only coincidentally thrust her modest breasts outward.

“Forgetting something, Rainbow?” Twilight said, decidedly looking away from her friend's lithe body.

“Hey, we're all gonna wake up naked in dreamland anyway, right?” Rainbow Dash shrugged. “Why bother?”

“Indeed. In my youth, there were times where neither I nor my sister bothered with garments, save for certain special occasions.” And with that, Luna neatly undid the tie to her dressing gown and allowed it to slip off her shoulders to pool upon the floor. The Princess of the Night was somehow even more imposing without clothing, as if the cloth were holding back the perfection of her form.

“Really?” Twilight dragged her eyes up the length of Luna's nigh-amazonian body, all the better to focus on her face (and the bemused smile on Luna's muzzle). “I thought all those paintings were ... embellished?”

“To some extent.” Princess Luna shrugged. “But we didn't come here to discuss art history.”

“Ah. Right.” Twilight smoothed out her pajamas, then settled on the far edge of the bed. “Let's ... let's do this. But I'm telling you, my dreams are probably going to be really boring and they might even put you to sleep. Or ... double sleep. Or something."

"Yeah? Might as well see for myself then, huh?"

"I ... I guess so." Twilight said, and closed her eyes.

A curtain parted.

Twilight squinted against a bank of suddenly-bright lights. By reflex, she held a hand up against the glare-- at which point she noticed several very important things.

She was naked.

She was naked on stage.

She was naked on stage and she didn't even have any notes.

“Not this one again.” Twilight muttered-- though thankfully not into the slim microphone on the podium in front of her. A podium that was far too narrow to hide any part of Twilight's bared body to any degree. A red-hot blush rose up in her cheeks and upper chest as Twilight squirmed in the warm, open air of the auditorium.

And in the audience, was ... everypony.

At least, it seemed that way. There wasn't an empty seat in the house, as seemingly the entire adult population of Ponyville and Canterlot combined had been crammed in. Applejack, Rarity, and all the rest sat there in the front row, looking up at her. Behind them, Trixie and Starlight Glimmer sat alongside various notable citizens of Canterlot, and behind them were even more ponies, row after row of them. At least there weren't any foals present, Twilight absently noted. Maybe they were checking ID's at the door.

Twilight tightened her fingers on the edge of the podium and closed her eyes. Unbidden, a public-speaking cliche came to mind:

Just imagine everypony in the audience is naked.

And when Twilight opened her eyes, they were.

The audience didn't seem to notice the change-- even with their clothes suddenly, inexplicably gone, they kept their eyes on Twilight, expectant, not bothering to cover themselves.

“That's right. It's just a dream.” Twilight said. “My dream.”

Twilight cleared her throat, then spoke up, her voice effortlessly carrying through the hall. “I'd like to thank you all for com-- for attending this lecture.” As she spoke, the words built up on one another, as Twilight knew exactly what she was here to talk about.

“The subject of alicorn sexuality has been a subject of discussion for quite some time-- albeit typically not of the academic variety. There are countless paintings, engravings, and anonymously published texts that portray Equestrian Princesses in a somewhat ... racy manner. In many of them, there is a common thread that assumes that, along with the wings, horn, and slightly taller stature, an enhanced libido is a major part of being a Princess.”

“For a thousand years, this has mostly been a matter of conjecture, as Princess Celestia was the only Princess in all of Equestria. However, with recent ... developments, we have the opportunity for further study.”

“I posit that the average Princess is no hornier than the average 'normal' pony. Given my time as both a plain unicorn and as a Princess--” Twilight took a moment to splay her wings out and arc her back subtly, using her own body to demonstrate her point. “I've found that my personal preferences have not changed in the slightest. However, anecdotes are not data-- therefore there is a need for further research. Thankfully, the presence of other Princesses allows for an experiment. Princess Luna, Rainbow Dash-- would you two come out please?”

On cue, Princess Luna and Rainbow Dash walked in from either side of the stage. They were nude, of course-- and proudly so. Tails and wings bobbed with each sashaying step, the two ponies displaying themselves for the crowd-- for Twilight. At the back of her head, Twilight wondered if she was dealing with the 'real' Luna and Rainbow, or some sort of dream-facsimiles thereof. Either way, they were there, and they were quite eager to help.

“Thank you both for volunteering.” Twilight nodded. “If you would, please sit on the examination tables, and place your hooves into the stirrups.” The side-by-side tables of padded vinyl and polished steel might not have been there when Twilight started her lecture, but she wrote that off as just more dream logic.

Again, Luna and Rainbow complied, leaning back upon the examination tables, spread-eagle. A few ponies in the audience murmured amongst themselves, leaning in closer.

“As you can see, from the neck down, Rainbow Dash and Princess Luna are anatomically identical.” Twilight bit at the inside of her cheek as she glanced from Rainbow's pussy to Luna's, then back again, savoring the sight of their crinkled lower lips so lewdly exposed. She walked between the two examination tables, reaching out with either hand to run down the length of both her friends' bodies. Rainbow's svelte form wriggled beneath Twilight's touch, and Luna's breath hitched ever-so-slightly.

“The experiment is a simple one.” Twilight continued her lecture to the rapt audience. “I will apply similar levels of stimulation to both a Princess, and a normal pony, and we can all observe the results. And, while the most comprehensive study would include an earth pony and a unicorn as well, I only have two hands.” Twilight winked at the crowd, and a faint, amused chuckle rippled through the room.

This done, Twilight turned around (coincidentally giving the audience a lovely view of her derriere) to face her experimental subjects. The very act of getting into place alone had gotten them worked up-- both Luna and Rainbow Dash were breathing harder, even if Luna did a better job of hiding it. With Luna on the left, and Rainbow on the right, Twilight slid her hand down both ponies' inner thigh, savoring the feel of the smooth, warm flesh. And then, her fingers found something smoother and warmer still as she brushed fingertips over their respective pussies.

Twilight wasted little time-- she pushed the two middle fingers of each hand between the waiting, needy folds of pegasus and Princess both. Luna's pussy was tighter than Rainbow's, but only slightly. Both ponies were nearly dripping, and the added stimulation only got them wetter.

Twilight tilted her wrist and curled her fingers just-so, pushing through slick inner walls to find just the right spot. And sure enough, she did, as both Rainbow and Luna moaned in exquisite pleasure. Twilight worked her fingertips back and forth, massaging each pony's g-spot, driving them to further and further arousal. Rainbow Dash was the more active of the pair, bracing her hooves in her stirrups as she arched her whole body, grinding herself against Twilight's hand. Luna was slightly subtler in her reaction, though it wasn't long before she reached up to fondle at her own heavy tits, tugging at her nipples as Twilight fingered her.

“As you can see,” Twilight said, “while both subjects have slightly differing reactions to stimulation, neither is particularly hornier than the other. Which is to say ... they're both horny sluts.” Twilight blinked as the words left her mouth-- even though she knew she was right. She was a scientist, after all. “But, just for further clarification, I will now use my thumb to massage each subject's clitoris ... “

The added sensation got even Luna to moaning, her breathy gasps echoing through the auditorium. Twilight kept on going, finger-fucking faster and faster, 'til heavy, musky droplets of each subject's nectar were dripping down her knuckles.

Luna bucked her hips, flailing out with one hand, entwining her fingers with Rainbow Dash's. No sooner had they clasped hands, the two test subjects gasped in unison. Tight walls clenched around Twilight's fingers, and the both of them shuddered in wanton pleasure.

The audience broke into applause.

Twilight eased her sticky fingers out of her friends, then turned around again. She waited for the clapping to die down, and then cleared her throat. “As you can see, the simultaneous orgasm under the same amount of stimuli suggests that a Princess is no more or less horny than the typical pony. But, in the interest of full transparency, I'm ready for ... further demonstration.”

Twilight idly licked Luna's nectar from her fingers, and smiled as Princess Celestia and Rarity both walked onstage, each one a study in alabaster elegance. Celestia carried herself with effortless grace, while Rarity stood a little bit stiffer, as if she were walking down a runway (despite the utter lack of any clothing to model). Behind them, Princess Cadance and Applejack stood in the wings, awaiting their own turn on the examination table.

Twilight managed not to drool as she sized up the naked, eager, perfect bodies of her test subjects, but it was a close thing. She took in a deep breath and shivered, relishing the sensation of such unquestioned authority.

“I fucking love science.” Twilight murmured to herself.

And then she woke up.

Somewhere during the night, Twilight had wriggled out of her pajamas, and found herself wedged in between Princess Luna and Rainbow Dash's respective nude forms. Despite the unexpected awkwardness, the warm, soft feel of other bodies curled against hers was entirely too pleasant.

Twilight looked up at the canopy to Luna's bed, and wondered if she could teleport away without waking either of her erstwhile bedmates.

“Damn, Twilight. That was wild.” Rainbow Dash opened her eyes and smiled. So much for that plan.

“Uh.” Twilight blushed. Squirmed. “Did I ... experiment on my own dream versions of you two, or was it more ... personal?”

“'twas both.” Luna said. “In the realm of dreams, the distinctions between what is and what is not can become ... blurred.”

“I'm sorry!” Twilight said. “I didn't mean to, uh ... objectify you like that. Or, uh, subconsciously maybe I did because it was a dream but actual-consciously I'd never make you do anything like that.”

“You sure? 'cause it was pretty hot.” Rainbow Dash grinned, and leaned up to kiss the tip of Twilight's nose.

“I find it intriguing that even your erotic dreams are academically inclined.” Luna didn't bother hiding her wry smile.

“Well, uh. Rainbow Dash got a trophy in her dream, so I suppose it really is a window into any given pony's deepest desires-- not just the sexual ones, either. So ... what just happened totally isn't weird and awkward and stuff. Right?”

“You are learning fast, Twilight Sparkle.”

“So is going into ponies' dreams going to be this sexy all the time?” Twilight asked.

“For the most part, yes.” Luna said with a shrug.

“Sweet!” Rainbow Dash said.

“Except for when one must sometimes battle a dream-eater or some other monstrosity.”

“Sweet.” Rainbow Dash said again.

“Hopefully we won't have to worry about that anytime soon.” Twilight leaned her head back against Luna's chest (which made for quite the comfortable pillow, she had to admit).

“So we can keep doing the dream-magic thing?” Rainbow Dash perked her ears.

“... sometimes.” Twilight said before she even knew it. “This is ... nice, but honestly if I spent every night like this I don't know how I'd function.” She stretched out a little, draping an arm across Rainbow Dash's shoulders. “This has gotta be the first time I've woken up more tired than when I went to sleep.”

“Alright, alright. We'll take it easy the night after tomorrow.” Rainbow Dash said.

“The night after tomorrow?” Twilight blinked. “Why then?”

“'cause there's one more pony who's head we've gotta look in before we take a break.”

“Whose?” Twilight said.

Rainbow Dash just grinned, and reached past Twilight to run her hand over Luna's flank.

“Hers!”
