Loosen Up

Darkness. Uncertain, exciting darkness. Though Rainbow Dash so desperately wanted to open her eyes, she could not. Twilight’s hands covered them. “We’ve been walking forever, Twi. If you’re going to show me a surprise, can I see where I’m going?”

“Ah ah, no peeking, Rainbow. You don’t want to spoil it for yourself, do you?”

“Can I at least get a hint?

Twilight huffed. “Oh fine. It’s something that you said has been on your mind for awhile. A fantasy!”

“Oh c'mon, you know how many fantasies I have. Racing fantasies, food fantasies, fantasy pranks...”

“A sexy fantasy.”

“That doesn’t narrow it down at all.”

Twilight’s guiding step came to an abrupt halt before those gentle hands pulled away from Rainbow’s eyes. “Okay. We’re here. Open your eyes!”

Eager anticipation gave way to confusion as Rainbow Dash looked at a solid oak door before her. A featureless stone hallway surrounded the pair, a far cry from the regal marble and gold of the rest of Canterlot Castle. A window to the outside revealed the sun setting over the horizon, bathing the city below in brilliant gold-orange hues. She looked back at Twilight, bewildered. “Uh… A door?” She smiled politely, expecting some manner of explanation or elaboration on how a door could possibly be surprising or sexy.

“Yes, a door.”

Rainbow sighed. “You’re not going to tell me until I ask why, are you?” After several long moments of silence, and thinking Twilight might explode if she didn’t ask, she caved. “Okay. What’s sexy about a door?”

Twilight bounded towards said door with a giddy spring in her step, stopping just short and turning back to Rainbow. “You know that little fantasy you told me about a few weeks back? The one where you get passed around between ponies like a sex toy?”

“O-oh, uh, that one?” Rainbow asked, a rush of heat rising to her cheeks. “Yeah, I remember.”

“And how you said you wanted to see what bedding Celestia and Luna would be like?”

Rainbow’s body stiffened. “You didn’t…”

“I did!”

“Do they also have…?”

“They do!”

Rainbow simply stared at Twilight for a time. A meeting the princesses definitely explained the purple mare’s attire: a long sleeve black shirt accompanied by a knee-length black skirt. It put her own yellow sleeveless tee and blue athletic shorts to shame. “You told them about… Ah, they probably think I’m some kind of huge perv now!”

“C’mon, Rainbow Dash,” Twilight cooed, gliding over to embrace the embarrassed, disconcerted pegasus. “They don’t think anything less of you. Why do you think I’d bring you here if they said no?” She delivered a swift peck on Rainbow’s cheek and ran a hand through those rainbow locks. “Besides, if anyone in Equestria is a massive perv, it would be either one of them. Or both.”

Shooting Twilight a look, Rainbow sighed and rested her head on her marefriend’s shoulder. “Are you sure this is okay? I mean, aren’t they like your teachers? Or, unless you’re into that kind of thing. Or what if they want to get really kinky and then it gets all weird and --”

“Do you trust me?”

How Twilight held the power to stop her in her tracks with a few simple words, Rainbow never quite grasped. She loved her for that, among other things. With a grin, she returned the kiss and ruffled the alicorn's mane. “Yeah. I trust you. And, uh, thanks for doing this. It means a lot.”

“Of course, you big softie.”

“Shut up.”

As Twilight broke off and moved towards the door, she paused. “Oh, I almost forgot!” The magenta aura of her magic sparked to life and enveloped Rainbow Dash in moments. It swirled around the confused pegasus, crackling and casting her in the magical glow before dissipating as fast as it arrived.

“What was that?” To Rainbow’s surprise, nothing visibly changed.

“Elasticity spell. You’ll thank me later.”

Rainbow opened her mouth to ask the flurry of questions that rushed to her head, but closed it soon after. “Whatever you say, egghead.”

Twilight stuck her tongue out at her beloved company before tapping on the door in quick succession. A moment passed without any change until a corner of the door lit up in a white glow. The other top corner followed suit, followed soon after by the bottom corners. Lines shot from the points of origin to the door’s center, where a circular lock turned with a low, grinding squeak of wood against wood. Once the lock finished its rotation, the lights faded and silence returned. For a moment.

“Oh no, they’re here already? I’m not decent,” came Celestia’s muffled voice from behind the door.

“Then get yourself decent, Sister. Heavens, it is a wonder how you remember to raise the sun.”

Celestia grunted. “We are not having this conversation right now. Just stall them a little, okay?"

Luna’s voice returned after shuffling of feet, loud enough to address the waiting ponies outside. “Do come in.”

With that, Twilight pushed the door open and motioned for Rainbow to step inside. The bland, dreary stone walls gave way to a vibrant array of oranges and yellows. Her feet practically sunk into the fur of a shag carpet, the arrangement recreating a sunrise in a much cozier form. At the end of the room sat a sun-embroidered bed large enough for several ponies to lay in, or perhaps big enough for one greedy enough to hog all the space for herself. Considering how many pillows lined the top, most likely the latter.

A hallway to the right saw the color from bright and rich tones shift to far darker shades. In this hallway, Luna soon appeared after casting a glance over her shoulder. She wore a grey shirt depicting a cat sitting comfortably on the edge of a crescent moon. This and a pair of nylon running pants gave the Princess of the Night an uncharacteristically casual air. “Hurry, Sister. This is what you get for waiting until the last second.” She offered the newcomers an apologetic smile and bowed. “Apologies, Twilight Sparkle and Rainbow Dash. My sister is not the most punctual of ponies when it comes to… Personal meetings.” Noting the look she received both both parties, she looked down at her attire. “What? Is one not allowed to relax in the adorable modern wear?”

Before either pony could answer, Celestia burst into the room. “Sorry, you two. I thought I’d have a bit more time to pick something out. But hopefully this should suffice.” She wore barely anything at all. A yellow polkadot bikini top struggled to hold back her ample breasts -- a dam liable to burst at any moment. Her shorts, or excuse for a pair, came down just enough to cover her cutie mark, depicting a manner of unorthodox eclipse on her thighs.

Princess Luna looked her sister over and sighed. “You would pick that.”

“The dressing room is much harder to navigate when I have no time to decide.” Celestia strode over to the bed and sat down with a huff, flopping onto her back.

Luna did the same, though made up for her sister’s lack of class by sitting up straight and crossing her legs. “You may as well have worn nothing at all.” She paired he quip with a sideways grin.

Celestia let out a wry chuckle. “It’s not like we’ll have these on for long, anyway.” She sat up, adjusting the tight band around her cleavage so as to stave off breaking a bit longer. “But I’m getting ahead of myself.” Patting the space on the bed next to her, she motioned to her two guests. “Welcome, both of you. Don’t be shy. Sit down and let’s chat.”

Both ponies took heed, sitting on the edge of the bed between their hostesses.

“So Rainbow Dash,” Celestia began, reaching over to the bedside nightstand and opening the drawer, pulling out a bottle of chardonnay. A wave of her finger and spark of her horn materialized a glass, which she filled and promptly downed. “Twilight tells me you have some interest in getting down and dirty with Luna and I?”

Rainbow Dash hesitated, more so from hearing Princess Celestia of all ponies speak in such an unprofessional manner. “You could say that, yeah.”

“No need to be modest.” Celestia poured herself another glass and took a more reserved sip. She licked her grinning lips before continuing. “She went into great detail.”

“She did?” Rainbow cast a look Twilight’s way. When her marefriend nodded, she cleared her throat and scratched the back of her neck. “That’s not bad, right?”

“On the contrary,” replied Luna, recrossing her legs in the opposite position. “It is not often we find mares willing engage in such acts, let alone ones who are open to partake in them with both of us.”

After a pause, Rainbow motioned to the bottle of chardonnay. A filled glass floated over to her and she brought it to her lips. A bitter flavor with overtones of pineapple and a hint of vanilla graced her tongue. Not bad, she thought. A little liquid courage might go a long way, given her position. “So, since you know everything, how did you want to start?”

Celestia levitated the bottle and glass back to the nightstand and looked over to Rainbow with a furrowed brow. “Not everything, exactly. There are a few more things we’ll need to know before we get into any lewd activities. You have a safe word with Twilight, yes?”

“Antiquing.”

“Good choice, good choice. I doubt even Twilight would go antiquing unless forced to.” An irksome glare from Twilight made her mentor giggle even harder. “And what about you, specifically? What is it that you like? Any fantasies or desires you wish to explore?”

“Um… I’m not into anything too fancy, I guess. Just standard stuff. Honestly whatever you think works’ll be fine.” Celestia’s brow straightened and a small frown graced her face. “Is that the wrong answer?”

“No,” Celestia assured, though she regarded the pegasus with a skeptical eye. “It isn’t wrong, but if the intent was just to sate the wants of Twilight, my sister and I, would you really be here?” When she received no immediate reply, she pursed her lips and leaned back, crossing her legs as though a lecture sat on the tip of her tongue. “I’ve been around long enough to know the innermost wants and needs of many of ponies. But do you know how I came to know these things?”

Putting her hand to her chin, Rainbow pondered. “Magic?”

Celestia smiled. “No. It’s because they told me. As gifted in magic as alicorns are, Rainbow Dash, we cannot read minds. Yours included.” She shot a glance Twilight’s way. “She knows what you want, but hearing it from her is one thing. The rest has to come from you. If this is to be an experience we’ll all enjoy, we need to ensure that you will also enjoy it.”

A pit formed in the depths of Rainbow’s stomach. The words verged on the tip of her tongue, on the brink of release, yet she couldn’t say them. Every syllable caught in her throat and she was left a mare struggling to form even an acknowledgement.

“Would you care to reconsider, Rainbow Dash? There is no shame in doing so,” Luna said.

The thought of wasting Twilight’s given opportunity spurred the fountain of words to flow. “What? Nah, I’m good, I swear. We can start whenever you guys are ready.”

Celestia looked to Twilight again, and the following shrug did little to dispel the trouble on her brow. “If you do wish to start, then we will. But before we do, I will need to know where your line is. What you not into, as it were?”

“Do I have to say all of them out loud?”

“Some of the more extreme ones I consider lines unless specified.”

“Thanks.” Rainbow breathed a sigh of relief. The rest came far easier. “So the obvious ones, and nothing, ya know” - she gave her ass a quick tap - “back there. That’s reserved.” A resurgence of blazing heat rose to her cheeks as she gave Twilight a thumbs up. “Let’s see… No bondage stuff, nothing overly mean, and… That’s all I can think of.”

“All very understandable limits. And certainly limits we can abide by, right Luna?” The Princess of the Night nodded. “And you as well, Twilight?”

“Of course.”

“Good. Now, are you sure you’re ready, Rainbow Dash?” Celestia asked. A steely-eyed look and a firm nod was all the answer she needed. “Very well. Then you may start things off. Maybe get out of those clothes first, if you’re so inclined?” Her smiled turned devilish.

Rainbow’s breathing quickened. Every heartbeat rang in her ears like cannon fire, drowning out the instinctual thoughts to run, fly, or both. Her hands gripped the sides of her shirt before pulling it over her head after some hesitation. She sucked in a breath as her bare nipples met the air. The world didn’t end and nothing exploded, so she relished the small victory. She cupped her breasts easily, as not much was there to grab. Her drive to please and impress pushed her forward through the hard wall of apprehension.

“A lovely set, Rainbow Dash,” Luna remarked in a warm, seductive purr. In her seated position, she shimmied her pants down to her ankles, revealing a pair of black lace panties underneath.

“Th-thanks.” Rainbow stumbled over such a simple word as the familiar pinpricks of tension crossed over her skin. It did little to impede her movement, however as her hands trailed down her toned abdomen and around her hips, thumbs hooking into the sides of her athletic shorts. By now, her wings stood at full attention, outstretched and aching. A moment later, her pussy and ass lay exposed and her heart threatened to break from her chest. She tried to think of something else in a desperate attempt to ease the internal cacophony. Her trained gaze on the other ponies found an encouraging distraction. Three princesses, three bulges.

Score.

“You should have asked us about a romp sooner, Twilight. You picked a keeper for sure,” Celestia said. She beckoned Rainbow closer before pulling on the front of her bikini. The poor thing broke after a second of additional strain, letting the princess’ large breasts bounce free. Once within arm's reach of the pegasus, she took a soft handful of blue-furred ass. “Now then, my little pony. What say we work up from the shallow end, hm?”

Celestia motioned to the open spot between her and Twilight, where Rainbow promptly sat. “Twilight, you don’t mind giving Luna and I a demonstration of your technique, do you?”

“Not just a demonstration." Twilight brushed over the delicate feathers of her lover, trailing her fingertips to rest on the connected musculature. "We’ll give you both a nice show. Won’t we, Dashie?”

That name. Twilight’s nickname tripped a trigger in Rainbow’s mind -- akin to a switch. It was a lovely name given by a lovelier mare, a name that guaranteed protection, safety and comfort in the warm arms of her lover. All she had to do in return was provide service in any manner desired of her. If nothing else, her element helped fulfill such services.

Anxiety persisted, but Twilight, as always, kept much of it at bay.

“Let’s get these down for you,” Twilight cooed. Her hands worked such wonders on Rainbow’s wings on the regular, as evident by the tension’s slow but sure release from those sensitive limbs. She was her temptress, her siren, and in such times of uncertainty, her rock. Her breathing steadied as the pair of skilled hands worked along her wings. “Who’s my good girl?”

Rainbow dawned a sheepish smile. Even in the company of Equestria’s rulers, she could not resist such praise. “I am…”

“Of course you are. Your wings feeling better?” Rainbow nodded and gave the appendages a stretch. “Good. Now, roll over for me, would you?”

Rainbow obeyed, adjusting her wings as to avoid any further discomfort. Looking up at Twilight, she soon saw the reason for her rearrangement. A pair of purple thighs straddled her head, a darker colored cock she’d become well acquainted with rising to attention between them. As it rested on her nose, the intoxicating scent of her marefriend’s musk wafted to her nostrils. Her body responded in kind, squirming with anticipation of what was to come.

“Be still, Dashie. You’ll get your treat, but you know how to get it.”

As Rainbow reached up to take hold of her awaiting prize, Twilight’s hand stayed her. “Only your tongue.”

A firm order, and one Rainbow could not resist following. Her tongue dragged along the hot, pulsing flesh of Twilight’s cock, her body ablaze in the dueling flames of embarrassment and lust. She knew these sensations all too well; she chased every opportunity she could. Twilight typically wore no panties in public, so if an itch ever needed to be scratched, to have that throbbing cock slipped into a more-than-willing throat, they snuck away to some secluded place to indulge. Corners, alleyways, bathrooms, it never matter. Every drop of seed she swallowed served as a fitting token of appreciation.

For Rainbow, keeping herself restrained never got easier. Still, the prospect of misbehaving and being branded a “bad girl” was not one she wished to entertain. Not in the presence of such important company, anyway. She gripped the bedspread, anything to keep herself from disobeying.

“Don’t forget these.” Twilight reared back on her legs, letting her pair of heavy balls rest where her cock had been.

Rainbow took a moment to let the cashmere-soft skin of Twilight’s balls rub against her face. The blissful heat of said sack complimented the burning in her own cheeks, each giving the other with the same gift in kind. After a tender kiss to each lovely orb, she provided a similar treatment as she had before. Licking, kissing, sucking the pair and taking in more of the heavenly aroma surrounding her.

“Mmm, good girl, Dashie.”

Twilight took to dragging her sack along Rainbow’s face, giggling as she did so. “You like that? My big ol’ balls all over your face?”

“Y-yes.” Responding proved difficult for Rainbow due to her inability to fully speak through such a pair of nuts.

“I know you do, my dirty little pony.” Twilight brought herself to her hands and knees over Rainbow, her face inches from the pegasai’s glistening slit. “Does that mean you're ready for the next step?” Her chuckle took on a dark edge after the vigorous nod she received in response. “Good. Open wide. Three taps to stop.” After a few moments of adjusting her alignment, she pushed the head of her cock past the awaiting pair of lips.

With just the tip in, Rainbow flicked her tongue at the opening slit and lapped up the gathered precum. Delectable, as always. No amount of preparation could prepare her for the shock of Twilight’s tongue against her own slit. More of her Mistress’ cock gradually slid into her mouth and she accommodated as she could. While not an unfamiliar position to the two, they did not engage in it often.

Rainbow whimpered, fistfuls of bedspread tight at her sides. In and out, in and out. Slow, controlled movements from Twilight brought the blissful catharsis of feeling the mare’s cock in her mouth. She closed her eyes, jerked back to reality every few strokes with a teasing lick at her folds. Such relaxation and rising tension from the teasing coexisted chaotically, no force fully in control. Time held no meaning, only the spaces between the licks at her pussy and constant, quickening thrusts down her throat.

“How's it taste, Dashie?”

Rainbow lifted her hand and put up her thumb.

“Wonderful. Mmm, I think I’m getting close.” With her downward thrusts, her balls practically smacked against the pegasai’s nose, though not enough to cause any real harm.

Knowing the inevitable drew closer, Rainbow braced herself. The loud slapping of Twilight’s balls smacking against her coupled with their shared moaning delivered a sweet ring to her ears, the musk from her marefriend long since driving her into a wild high. Pressure built in her loins to a fever pitch. The teasing foreplay worked far too well, as it always did. She needed to taste it, to feel the hot rush of seed spill down her throat. Swallow it all. Every drop.

Her hopes were dashed when Twilight pulled herself out before her rightful treat could be given. Before Rainbow could ask what the big idea was, her found her head turned to her right and someone else forced themselves between her lips. Shock and bewilderment snuffed away euphoria as she looked into the eyes of Luna.

“While I do enjoy the performance, Twilight Sparkle, I am only so keen on using my hand for relief.”

“It’s quite alright, Luna. Besides, I’m sure Dashie wouldn’t mind both of us on her at the same time, would she?” She got off the bed and spread Rainbow’s legs. As she pressed herself against the wet, awaiting folds, she awaited reassurance from the mare below.

The pegasus practically squealed in delight, but Luna’s cock in her mouth prevented much of the sound from escaping. She surveyed the now-nude Princess of the Night in all her splendor. The tell-tale lines of a toned musculature traveled along her thighs, abdomen and arms, sketching the figure of a warrior more so than an athlete. How she’d never noticed the princess bared a comparable physique to her own, she wasn’t sure. A longer life left a lot more time to train.

Both mares claimed her at the same moment, sending Rainbow reeling. She’d never been with anyone but Twilight, so having another pony thrusting into her mouth provided enough shock to jar her senses. Luna’s cock was thicker than Twilight’s, though not near as warm. The softness made the jack-hammering far more tolerable -- pleasant, even. A rich, flavorful precum mixed with her saliva and dripped down the side of her mouth to stain the bedspread below.

“I can see why you like this one, Twilight,” Luna uttered through heavy breaths. Her hands passed through Rainbow’s locks, tugging fistfuls of hair to gain greater leverage on the subservient mare.

Rainbow struggled to keep her eyes open. Luna’s scent, while foreign, still kept her on the brink of sanity. An overlying aroma of blueberries with just a hint of raspberry replaced the undertones of magical ozone and lavender. Her thoughts drifted, overtaken as the cloud of lust thickened. The slapping of Twilight’s balls against her taint persisted as a fitting background track to the imagery dancing across her mind’s eye. One thing did persist among the joyous bliss of being taken by the two mares: fear.

Deep rooted, hard to shake, one she knew even before her relationship with Twilight escalated. Hiding it was easy most of the time -- just charge in with enough bravado and the fear wouldn't stick around. But times such as this, where she couldn’t approach matters with her usual reckless abandon and found herself at the mercy of others, it remained at the forefront. It only excited her further. Her wings shifted and twitched against the bed; though she seldom admitted such things, her body did not hold such reservations.

Twilight locked eyes with Rainbow and thrusted inside to the base, her moan a harbinger of her coming reward.

A warmth splashed across Rainbow’s inner walls and the look the two mares shared only intensified the moment. The numerous spurts of thick mare seed filled her to the brim, remnants oozing out from around the makeshift plug within. Twilight leaned against her form, breathing heavily enough to disturb the frazzled strands of purple hair about her face.

The sight and the intimate closeness of Twilight sent Rainbow over her own peak. Heavy throws of ecstasy shook her to the core. Her eyes shut tight, the discomfort keeping her grounded enough to restrain her spasming muscles. She grabbed onto her lover in a desperate bout to ride out her release. Her nails dug into the mare’s shoulders and legs locked around her hips to keep her close. For a time, she reached a calm the likes of which she rarely knew outside such intense pleasure.

“Good girl.” Twilight’s voice came out strained in light of the painful clawing of her marefriend, but she held on to her warm demeanor, nonetheless. She pulled out with a lewd pop and took her seat next Celestia who watched the display with an amused smile.

“Heavens… I could cum just from watching that.” Luna smoothed back Rainbow’s hair before giving her a pat. “You are indeed well behaved for a pet, but do not think that you shall receive special treatment from me for your obedience to her.” She pulled her slickened cock from its warm, wet sheathe and rested the tip on the pegasai’s forehead. “You earned her reward. Earn mine.”

As Luna moved back and sat on the bed, legs spread, Rainbow cast a glance back at Twilight. What did she seek? Approval? Reassurance? Something.

“Go on, Dashie. Work your magic.” She leaned in and planted a smooch on Rainbow's cheek.

It took Rainbow some time to work herself to a suitable position; her hands struggled to support her as the weight of an impressive afterglow remained heavy. Even in such a compromised state, Rainbow knew what to do. She lurched forward and rubbed her cheek against Luna’s length. She breathed in the scent of her princess once again to keep the aromatic high aloft. Soft, pleading moans left her as she trailed from base to tip with tender kisses.

“Perfect.” Luna’s voice starkly contrasted from Twilight’s. While Twilight put on airs of a seductive temptress -- something she learned how to do from several debaucherous books -- Luna held it firm. It was her voice.

The way Luna’s grip kept hold of her hair, the way she drew her in with only a few well-chosen words and exuded such an aura of power and control shook Rainbow to the core. The Princess of the Night, a master of her craft, knew exactly how to handle a mare.

“Next step -- erm, Dashie.” Almost exactly.

Rainbow’s skilled lips sealed around the tip of Luna’s rod and elicited a pleasant response. The hand on the back of her head pushed her down further. She struggled to adjust and keep her breaths from catching as she was made to take the full length in rapid succession. Hefty balls smacking against her chin, coupled with moans from the pony they belonged to, overpowered her own meager vocalizations.

“You are quite the suitable cocksleeve, are you not?” Luna laughed after receiving a single tap on the thigh and what appeared to be a nod as she kept up her pace. “Mmmf, such an obedient one, too. You wouldn’t dare spill a drop of my seed, would you?” Before any manner of answer could be given, she pulled herself from Rainbow’s mouth. “I do not wish for this to be over so quickly. No. I have a better idea.”

Luna laid back, hooking her arms under her legs and pulling upward. With her tail moved to the side, she revealed her puckered hole just below her balls. “You know what to do, I assume?”

No further instruction was needed. Rainbow dove in, her tongue licking and circling the outer ring of Luna’s asshole. With the princess’ ballsack resting on her nose, the rousing scent of musk sent her into a renewed tizzy. As the muscles she tasted began to relax, she pushed her slippery appendage inside. Though a depraved act, a tingling giddiness spread across her at the thought of providing such unadulterated satisfaction.

Luna grabbed the back of Rainbow’s head and pushed her deeper, resting her feet on the pegasai’s lower back. “Right there, girl. That’s it…” Her grip remained firm, though she snuck in a scratch or two behind the ears for good measure. She kept her thighs spread as she could to give better access to the pony below.

Rainbow kept up her efforts, sticking her tongue in as deep as she could and exploring Luna’s depths. A subtle tug of the hair brought her upward, away from the well-loved hole. She refocused her tongue on those heavy balls, worshiping them and generously coating them in saliva. Upon another tug of insistence, she brought one into her mouth and caressed it with her lips. The other soon followed before rainbow pressed her nose into the base of the midnight blue cock.

“You have been a good pony, Rainbow Dash. For that, you’ve earned your reward.”

No sooner had Luna said this than Rainbow found that meaty rod shoved into her maw. She barely caught her breath before the grip on her tightened, forcing her to bob on the pulsing slab.

“Oh yes, take it all! Heavens, I’m so close…”

Such a wonderful promise did not fall on deaf ears. Rainbow moaned in anticipation, relaxing her muscles so as to give Luna more freedom to use her as she pleased. The resounding plaps of every slap to her chin filled the room. Her back arched, her entire being ready for the delicious meal she would soon receive. She waited with bated breath as time froze around her.

With a final push inward, Luna cried out in ecstasy as she finally reached her climax. A stream of hot, potent seed spilled into Rainbow’s mouth and down her throat, much to both ponys’ delights.

“My my my, drinking it all down so easily?” Luna asked, struggling to catch her own breath.

Rainbow licked idly around the flared head in her mouth as she swallowed her prize. The taste drastically differed from Twilight’s cum, but it in no way dampened the enjoyable flavor. Luna’s hand released her hair, but she remained in her spot, suckling and lavishing the shrinking flare until she was sure no leftover cum remained. With the haze subsiding, a rather odd sensation made itself known. As big as Luna’s load had been, she’d never felt such a fullness. A hand moved down to her stomach but quickly retracted. How long had the small bulge been there?

“How are you holding up, Rainbow Dash?” Celestia asked.

Pulling herself free from the cock in her mouth, Rainbow barely kept herself up. “Me? I’m great!” Her chest rose and fell in rapid succession, the throbbing muscles and breathless exhaustion akin to the post-Wonderbolt's routine fatigue.

“You certainly responded well to my sister’s more forceful approach. Would you say that is something you like? Or, something we can provide?”

Working herself into a sitting position, Rainbow bit her lip. As embarrassing as such desires were, she trusted Twilight enough to tell her. Would trusting Celestia and Luna pose any more risk? Besides, the cat broke out of the bag and scurried off long before. “Uh, yeah. Yes. I like that kinda thing. A lot.” Weight lifting off her shoulders, the tension in her wings melted away and left them hanging by her sides.

A cheeky grin turned up the corner of Celestia’s mouth. “Ah, so you do like things. I was beginning to think you were here because you felt obligated.” She took one of the limp blue wings in a ginger hold and ran her hand over the rows of various feathers. “Is there anything else you’d like to mention before we venture further?”

The spark set by her previous admission lit the kindling in Rainbow’s chest. “While being a slut makes me fell, y’know, slutty, it’s kinda nice. Like, I don’t have to worry or care about anything else. I can just let someone else take the lead and follow them. Do what they want me to do.” With Twilight on her opposite side, she gave the bookish mare a light shoulder check. “How’s that for Element of Loyalty?”

Twilight rolled her eyes and kissed Rainbow on the cheek. “You’re the most loyal pet I could ask for. And the dorkiest.” She laughed as the other mare stuck out her tongue.

Looking down at her minor inflation, and considering Twilight’s spell, a plan hatched in Rainbow’s head. “But, there was something I wanted to try. If you’re up for it.” She tucked her wings back in and lay on her back. “I think I can go another time or two, and I want to get as much in me as I can. Mouth or down there, doesn’t matter. Fill me up!”

Celestia looked over at Twilight, who offered a reassuring nod. “You are sure you are ready? Would you like some water, perhaps?”

“Nah, I’m good.” Rainbow waved a dismissive hand and adjusted to a more comfortable position with closed her eyes, her breathing steadying. Though she herself only performed so much, fatigue began to set in. Her limbs grew stiff, but her spirit burned for more. “I can take dick like a champ.”

A brief silence fell upon the room.

“Is that so?” Celestia’s tone darkened and a mischievous edge lined her words.

Something solid smacked against Rainbow’s gut with a heavy thud, practically knocking the wind out of her. When she opened her eyes, her blood ran cold. The biggest dick she’d ever seen lay across her midsection. Celestia’s dick. Looking up, the evil glint in the eyes of the princess brought the twinges of fear and excitement rising back to her consciousness. “I, uh… Maybe water isn’t such a bad idea.”

“Of course.” The bottle of chardonnay and glass levitated over once again, but as the liquid passed through the spout of the bottle, it transitioned from wine into water.

Rainbow sat up and took the glass as though she did not witness the transmutation of one liquid into another. “I’m not even going to ask.”

“It’s a fun prank to play on nobles at parties,” Luna remarked.

After downing the water, Rainbow directed her attention back to the elephant in the room. “That’s… I mean holy...”

“You are not the first to react like that.” Twilight looked away with heated cheeks as Celestia shot her a wink.

Rainbow picked up the presented flaccid length, marveling at its weight without even a hint of stiffness. As her ministrations continued, the soft, malleable flesh firmed out, bringing with it an incredible warmth. She brought it to her cheek to relish in such heat, like the sun itself had taken on a phallic form and sat in her hands. Given who it belonged to, the analogy made sense.

Placing kisses along the dark-colored rod, she breathed in the scent of the solar princess. Peaches -- overwhelmingly akin to peaches, with just a hint of banana and the unmistakable musk of marecock. While an odd combination, it grew on her the more she breathed it in. She reached the base after a time and let out her tongue to lap at the pair of hoofball-sized balls below. The urge to ask how she kept such a set hidden during the day arose, but she snuffed out the question. Magic. It was always magic.

“Enjoying yourself?” Celestia asked with a giggle. She took a soft grip of the pegasai’s ear and worked it between her fingers which elicited a soft purr. “I take that as a yes. You’ve already progressed farther than most when they see what I have to offer.”

Rainbow smirked; even with no competition to speak of, she still won. She flashed Celestia a similar grin before taking the tip into her mouth. Her hands grabbed hold of the shaft as she went down, not fully meeting around the hot slab. As precum coated her tongue once again, she struggled to keep any from leaking from between her lips. It did not take long for her jaw to stiffen despite her persistence in sucking the princess off. She must not have hid the discomfort well, as a gentle hand rested on her cheek to stop her futile endeavor.

“Don’t hurt yourself, dear.”

Though Rainbow hated to admit it, all the confidence in the world couldn’t help her fit the huge thing down her throat. Breathing remained a need, after all. Before she could protest, Celestia pulled out and laid back on the bed, her slickened cock at full-mast.

“I think you’ll find sitting on it far more enjoyable.”

She didn’t need to be told twice. As she moved to straddle Celestia, Rainbow kept in mind the reassurances that such a beast would fit inside her. As much as she wanted to believe it wholeheartedly, the seed of doubt persisted, especially after her failure to suck it. In such uncertain times, she tried to imagine what Twilight might say -- something smart.

Sitting on a tree trunk is far easier than trying to eat it.

Close enough.

A renewed fire sparked inside Rainbow as she reached down to guide Celestia’s dick to her entrance. As she pushed back and let the flat head push past her lower lips, she moaned as though she were slipping into a warm bath. The entry proved easier than she thought, though sliding further down, she was surprised to find little increased difficulty. Once she reached the medial ring, a new sensation brought her to a stop. Twilight’s cock could typically reach this point inside her at the hilt, so she wondered if any more could fit. Thinking back to the spell cast on her and the lack of concern from any princess, she pushed onward. Once past that point, a wave of unbelievable pleasure overcame her.

A previously unpenetrated barrier within her gave way, stretching snuggly around the tip of Celestia’s cock. New, unexplored territory met the hot caress of cock, much to both pony’s surprise and liking. Before long, she’d finally worked her way down to the base. She sat at the bottom to catch her breath.

“Feel free to move at your leisure. Even with the spell, it’s probably a lot to take in.” Celestia smiled up at Rainbow understandingly. Her hands moved behind the pony on top of her and grabbed handfuls of plush, muscular rump.

Rainbow moaned and set her hands on the massive pair of breasts below for support. Go time, she thought. She raised her hips, the pleasant burn leaving her tubes and exiting her cervix before she brought herself back down, slamming it inside again. The suddenness rocked every nerve in her body, making her fur stand on end and her wings tremble. Once in a rhythm of slow, controlled movements, she let her hands travel across the soft, malleable mounds of flesh that supported her.

“Mmm, you like them?” Celestia asked before giving Rainbow’s ass a firm tap.

A sharp whinny escaped the pegasus, her body lurching forward as she struggled to hold herself up. The muscles in her thighs burned and her bounces spaced apart. As much as she struggled to stay above, to not fall onto Princess Celestia of all ponies, her body betrayed her. Her arms and legs gave way and she fell face first into the pillowy rack. Not a bad landing. Panting, she looked into the princess' eyes, trying to gauge her reaction.

The matronly princess simply smiled. “We’ll take it from here, Rainbow. You relax and… Enjoy yourself.”

We?

Another cock poked Rainbow from behind. Luna. “Ready for another?” Luna asked while pressing her length against the hole her sister already filled and continued to stretch.

For a moment, Rainbow thought of refusing and not taking the chance of reaching the spell’s limit. How could she pass up the chance to take two dicks at once?

"Go for it!"

“Splendid!”

Not a moment later, Rainbow cried out as Luna shoved herself in alongside her sister. The pair of cocks began to pump into her, both passing her cervix and into her their own respective canal as deep as they could go. Her breathing quickened, spurred on by the force of the two alicorns and her pussy stretched in a desperate attempt to accommodate. She buried her face in Celestia’s boobs and used the makeshift pillows to muffle her mewling moans.

“Such a tight snatch, Rainbow. Hopefully this won’t ruin it,” Celestia said with a giggle as she gave one of the blue-furred ears above a nip.

“And I thought your throat was a lovely cocksleeve. Your nethers are just divine!” Luna’s hand came down hard on Rainbow’s rump to add to the debaucherous chorus.

Such lewd comments about her drove Rainbow wild, not to mention the sensations of being used in such a way. Being a cumdump for the most powerful ponies in Equestria, to have them use her as they may and fulfill their desires brought with it a tingling unlike any other.

As she continued to let the mind-numbing bliss of her position take over her senses, she found herself pulled from the comfort of Celestia’s cleavage and her mouth full of cock once again.

“Come on, Dashie. Give it all you got!” Twilight began to rock herself back and forth, her movements far slower than the other two princesses.

Rainbow refocused her attention on her marefriend, suckling and licking the shaft still wet with her own saliva and juices from before. Caution faded to the wind, walls fell and the cloud of lust overshadowed her thoughts. From the frenzied grunts and speed of the two fucking her pussy, it wouldn’t be long before she was filled to the absolute limit. She herself neared her own climax as the heat of the moment and the marecocks filling her holes overwhelmed her.

The first rush of white-hot warmth to shoot inside Rainbow sent her mind reeling. Her hands balled into fists as she resisted every urge to give in to fatigue or the ecstasy. Her inner walls could barely hold the sheer amount pumping into her, and she herself could no longer hold back her release.

Luna climaxed as she did, another load of spunk flooded her insides as her muscles spasmed and her soul shook. Every nerve ending numbed for a mere moment, taken by the clarity only an orgasm could provide, returning sharply to reality not long after. The warmth traveled down between her thighs, a mixture of the princess' cum, along with her own ejaculate.

Rainbow eluded passing out by a thread, holding on to consciousness only through Twilight’s quicker thrusts into her mouth and the urgent whispers.

“Oh yes, Dashie. I’m so close…”

Delicious, nourishing seed spurted onto her tongue after a time. How long? She could no longer tell. Rainbow relished the flavor and savored every drop she could before exhaustion won out. Her eyes closed, and the last thing her mind registered was the soft caress of Twilight.

“Good girl, Dashie.”

Rainbow Dash awoke to a beam of sunlight assaulting her eyes. With a pained groan, she rolled over. She opened her groggy eyes once safe from the rude intrusion. The familiar form of Twilight lay next to her, snoring as she always did yet would never admit to. One of the few quirks she had to get used to with her lovely egghead.

Realization struck her like an angry storm cloud. Her breath caught in her throat and she shot up. She felt her stomach. No bulge. She felt between her legs. No mess.

“Hey, uh, Twi?”

With a snort, Twilight woke and opened her eyes to meet her lover. “Oh, g’morning Rainbow.” Her mane, while majestic as ever, bared the tell-tale raggedness of a tossing sleep. Another sleeping habit she would not admit to.

“You didn’t happen to have a dream about a foursome with Celestia and Luna, did you?”

Twilight grinned. “Oh that wasn’t a dream, hun. It totally happened. And you were amazing, by the way.” She sat up and draped her arms around Rainbow’s shoulders, pulling her into an embrace before falling back onto the bed with her. “You weren’t kidding when you said you could take dick like a champ.”

Rainbow smirked. “Thanks, but that spell really helped, though. I mean, they were packing!”

Both of them laughed and both fell silent for a time after.

“Say, Rainbow…”

“Yeah, Twi?”

“Why didn’t you tell them right away what you wanted? They could have easily given you that kind of romp from the beginning if you wanted.”

Rainbow smiled before resting her forehead against Twilight’s. “Do you really want me to get into that? Have me start talking about my feelings and stuff?”

“Of course!”

With a huff, Rainbow got on top of Twilight kissed her on the nose. “How long have you known them, Twi?”

“Since I was just a filly. Why?”

“And how long have you known me?”

“Several years, now. Just a little longer than you’ve known them, though.”

“But do you think I know them as well as you do?”

Twilight paused. Her mouth sat agape in surprise and her hands came to rest on Rainbow’s back. “I… Guess I never thought about that.”

Rainbow tucked some stray strands of hair behind her ear and kissed Twilight again, holding the lip-lock for a longer time. “I knew them, but not enough to tell them that kind of personal stuff. Right away, anyway. You think I go around telling everypony I like to take it up the ass and get called a ‘good girl’?”

Twilight smiled the dorkiest smile imaginable. “It’s always weird when you’re right about something.”

“Hey! I’m right more times than you wanna admit.”

“Does that mean I can call you an egghead, too?” Twilight snickered before pulling the pegasus into a warm hug and kissing her cheek.

“Nice try, egghead.” A yawn interrupted Rainbow’s fit of giggles. “Ask me again after I’ve gotten more sleep. I’m still beat.”

“Love you, Dashie.”

“Love you, too, Twi.”

As Rainbow closed her eyes and let the soft stroking hand of her marefriend lull her back to sleep, she couldn’t help but smile.

Darkness. Blissful, calming darkness.
