All Tomorrow's Birthdays

Sunset looked towards Sparkle and focused on her. As off the rails as her plan to surprise and seduce Sparkle had gone, the fact was that she was here ready for a kiss.

“Sunny,” Sparkle murmured when Sunset leaned forward. There was a moment of hesitation in Sunset before she finally she held her breath and put her lips to Sparkle. It was a gentler kiss than the one she had given Twilight. Filled with uncertainty at first in both girls before they relaxed to each other. When they finally parted, Sunset found it hard not to smile.

“Now give her some tongue,” instructed Twilight.

Sunset's ears perked as she was reminded of watchful eyes. “Hey! We are tryin—mmnf.”

The instruction hadn't been for Sunset.

Sparkle seized that opening of Sunset's indignation to press her back and nudge her tongue firm and square into Sunset's mouth. Sunset’s emotions spun away from pique to passion. Being Prench kissed in so many minutes, by so many Twilights! She couldn’t deny liking it, as guilty of a pleasure as it might be.

Sunset led a stroke along Sparkle's side, and her wings opened. Sunset laughed, Sparkle giggled, and they were off, tipped onto the bedsheets in a playful roll of bodies.

Sparkle eventually let herself fall to her back, with her wings spread like a natural blanket. The feathers added a plush comfort to the weight of having Sunset settled on her.

Sunset moved a thigh in close in-between Sparkle's and grinned when she heard the 'Mmf!' come out of her at the touch. The kiss broke a second time with a panting on both sides. “Gotcha there, Sparkles.” After being teased by two Twilights, Sunset was ready to take any victory she could get! She began rocking against Sparkle, riding thigh against her groin.

Sparkle was too far flushed and squirming to give much of a response. Instead wedging her face underneath Sunset's chin to let out a few moans into the front of her throat. She then turned her head to nip at Sunset's shoulder.

That riled Sunset up all the more, getting her tail to flick with the hip motion. She felt herself start to ache at her own loins, but she kept the swaying pace. She wanted to feel her Sparkle shake with the pleasure of an orgasm and made sure of it with a drag of her leg along Sparkle’s sex, favoring the sensitive bump of a clit with each pass.

Sunset's tail swung a few times before she felt it lifting on its own. Soon after a sudden warmth pressed against her cunny. A glance back over her shoulder showed her Twilight with one hoof on her sun cutie’d flank while sparing a hoof for rubbing herself between the thighs.

Sunset couldn't see Twilight's smile over her sun-stamped curves but felt the mouth all the same. As well as the goading pinch that made her jerk in place. The darting press of tongue and the play of snout and nose teasing her clit had Sunset shaking until Sparkle clopped at Sunset’s chest with a huffy whine.

Thus spurred, Sunset started rocking again, with the heat of two different, yet similar lips on each end of her swing.

It wasn't long before all three were moaning their pleasures.

“Wherever do you think they went? It’s not much a party without the partiers,” asked Rarity as she began folding a tablecloth into a neat square with her horn magic. With the cider barrel drained and the party favors exploded there was the un-celebratory job of cleanup.

It was a job that fell onto Applejack, Rarity and Fluttershy's shoulders more often than not. Rarity snorted in annoyance at the dozing Rainbow Dash sprawled out on a table. A sharp yank at the tablecloth had Rainbow up and scattering the empty cups around her with a few surprised flaps before tumbling to the floor. “Hey!”

Applejack chuckled at the antics before sharing a glance with Rarity. “Ah can think of one thing at least two of them are doin',” she said with a coy tip of her head and hat.

Rarity looked puzzled before she suddenly leapt back to avoid being hit by a wagging pink hoof that stuck out from under the table.

“Oh! Oh! I know!” Pinkie exclaimed nudging forward through the pile of cups on the floor. “They are bee you cee kay aye en gee!” Pinkie somehow looked as bright-eyed as ever, despite technically being the one drunk under the table.

Fluttershy's eyes widened as she heard. “OH!...oh.” Her hooves going up to cover her mouth.

Rarity scoffed, “That's just ridiculous.” Her voice then dropped to a gossiping whisper, “Do you think so? With… herself?”

Applejack prodded Rarity on the shoulder. “Come now. Ya gonna tell me all them hours doing up your mane in the mirror you never want to give yourself a smooch.” She was grinning as she added, “Never felt a little generous for yourself?”

Rarity took on a fierce blush then sputtered a few halfhearted denials before puffing out her cheeks, staring daggers at the laughing Applejack.

“It's fun! Especially when you know everything that you like!” Pinkie confirmed cheerfully.

“Wait... what are we talking about again?” asked Rainbow Dash sluggishly, finally sitting up from her place on the floor.

Pinkie Pie merrily went on to describe the many ways she used the duplicating pool to provide a personal party for herself before charitably sending them out to Ponyville.

Rarity and Fluttershy turned competing shades of pink. Rainbow sobered up and had more than a headache to groan over. Applejack looked the least perturbed, likely owing to her farmer's experience.

Slowly, one by one, they looked towards the mirror in the room with speculative glances.

“Well, it doesn't sound… awful. Sunset did tell me of their respect for fashion,” Rarity ventured into the silence.

“I always wanted to try a double rainboom,” murmured Rainbow with eyes darting.

“…” Fluttershy didn't say, before quietly asking, “H-How do we know they would want it too?”

“I expect if they are us, they'd have the same sort of idea,” said Applejack, recalling her conversation with Sunset. With a small snort, she added, “Twilight went off on her own over there what… three times now?”

“Four! If you count her coming over here!” Pinkie Pie corrected with a big grin and bob of her head towards the hallway. She did love it when a party resulted in something special.

Sunset felt oddly divided by both arousal and jealousy. Twilight and Sparkle held each other with their muzzles locked in a heavy kiss. Like their wordless conversation before there was a kind of non-speaking intensity in their movements with each other. Could Sunset ever hope to match that kind of passion?

One of the Twilights opened an eye and smirked with the corner of her mouth at her. Sunset flushed, realizing just whose flavor they were sharing. The second Twilight now looked at her staring and giggled, breaking the kiss. With a conspiratorial glance to her twin, their horns lit in unison. The same shade of purple magic overlaid and pulled Sunset forward until she settled in-between the alicorns.

“You know this is totally not fair on me,” said Sunset as she looked at the two coy purple ponies. Having since long lost track of which one was which. All differences aside they were both equal when it came to teasing.

“Isn't it? You're getting served double by us,” said Left Twilight.

“You should have a two-hundred percent satisfaction rate,” said Right Twilight.

Sunset peered suspiciously at the pony to her right and started to turn towards her.

Sparkle on the left gave Sunset a clopping spank on the cutie. “Gotcha, Sunny!” she said with a giggle, putting her nose on Sunset's shoulder.

“Is this my life now? Toy to a pair of purple princesses?” Sunset sighed dramatically.

Sparkle perked at that particular mention. “Twilight, do you have toys?” She wondered with a contemplative look in her eyes. She had seen ponies use plastics and rubber but was stuck to ask further on what kind of adult sex industry Equestria had.

Twilight nodded at her counterpart. “Applejack could show you every aspect of Earth pony ingenuity when it comes to mechanical analogues, but I prefer magic.” Now turning to Sunset, Twilight grinned. “And I know just the pony to use it on.”

Sunset couldn't tell if Twilight was more excited for her or a chance at using a spell. “Use what on?” When Twilight's horn started to glow Sunset had precious few seconds to read the spell forms, and her eyes grew wide. “Wha— w-wait...!”

The spell wasn't painful when it struck if anything it felt like a tide of heat and dancing tickles running along Sunset’s flanks. Enough to make her legs kick at the air as she groaned.

Sparkle gasped in surprise, “Sunny! You... you have... a... oh…!”

Sunset stared at herself then at Twilight. “When did you learn this?”

Twilight looked immensely pleased with her work. “I got the idea during a magic duel I had a while back. I twiddled with it after I saw that it was less of a challenge to do only bits of the spell. I only added what mattered in any case. How does it feel, Sunset?”

“Kinda stiff actually,” replied Sunset sardonically. A curious bump by Sparkle's hoof had her shiver. “Ah!”

Sparkle prodded a few times. “Are they all that big?” She marveled.

“Like I said before. We're all pony here,” chuffled Sunset. A touch by Twilight's lips had her perk. “Ah!”

Twilight stroked her nose in a line along Sunset's endowment. “It appears that you're just as sensitive. Maybe even more so,” she murmured into Sunset's lap.

Sunset quaked some from the sensation until Sparkle leaning on her side settled her body’s trembles, though not the needy throb in her loins. “It would be nice to be able to feel you like that, Sparkles,” admitted Sunset with a newfound empathy for colts everywhere. She looked down at the princess between her legs. “Would it work like a normal one too?”

“The spell imitates and translates feelings when it can. So, it should react like—” Twilight paused and moved in to put a warm kiss on the crown of Sunset's shaft. For Sunset, the pleasure was felt in a strange duality, like having her clit teased at the same time as her newly grown cockhead. It made both parts of her ache, and her thighs hugged around Twilight’s neck as she gasped from it.

“—mmm. Like that,” Twilight finished with a small laugh.

“I would like to try,” Sparkle said with the suddenness of someone deciding to dive into a pool. She clambered over Sunset and clumsily set herself astraddle her, forehooves on Sunset's chest. “Hey, you were on top the last time,” she added when Sunset grunted under her weight.

“I’m not complaining,” Sunset said before just looking up at Sparkle. The smile to her muzzle came easy and genuine. For all the zaniness of the situation, she was reminded again that Sparkle was here and she desired her. If unrequited love was the great sadness songs were written about, then love returned was just as powerful. Sunset reached and stroked over Sparkle's cheek, and she turned to nuzzle it fondly.

“Good,” Sparkle murmured though soon started to hesitate as she poised herself. “You're going to be my first,” she admitted with a nervous smile.

Sunset laughed then and sat up to put a fresh kiss to Sparkle's quivering lip. “And you're going to be my first too, like this,” Sunset replied before a shiver came over her then when she felt the warm squeeze of magic cradling her maleness. The magic lifted and held her shaft upright against Sparkle's lowering mound.

Twilight leaned against her counterpart's back, horn aglow with her helping touch. From Sunset's point of view, it looked like the princess was a perverse kind of athletic spotter. “Easy now. I'll guide you. Don't rush! It’ll pinch, but only for a bit.” Her tone was so professional it was almost as if she weren't talking about guiding her mirror-universe self onto a magically summoned penis.

Sunset was soon thankful for the support as her senses melted under the warmth of Sparkle's body. It was strange to think the grown stallionhood apart of her, but it soon became all Sunset could think about. The shaft was not quite as sensitive as her actual clit, but that made the friction and direct stroke a bit more pleasurable than raw.

There was a need to buck upward, and Sunset struggled against it, she didn’t want to rush Sparkle, but oh how she wanted to thrust! How she so very needed to!

“Su... Sun... Sunny!” Sparkle gasped and then shrieked when Twilight let her drop the rest of the way unaided. Star-spangled rump landed on Sun-dappled hips in a full sit with that flesh in-between them. For a few shared heartbeats, they locked eyes and took each other’s measure. At first it only took the barest of movements to have them both freeze with the intensity, but eventually, they could move just a bit without trembling.

One pump, then another and another after that. If Sunset didn't think about it, she could fall into a rhythm, bucking naturally at bouncing the moaning Sparkle on her thighs and hips. Sunset relished every press forward from the expectant clench at the sex to the squeeze of Sparkle's legs around her middle.

Sparkle reached for her with her forehooves and Sunset hooked hers around in the pony equivalent of holding hands. With a silly grin on her face, Sunset pulled Sparkle forward until she was close enough for a kiss at the ear.

“I love you,” Sunset happily sighed into it, blinking quickly to clear her watering eyes. Funny how something that had taken her over a year and two worlds to say came out now. Easy as silk.

“I love you too,” Sparkle replied without hesitation, her own eyes already wet. Sunset panted, her heart swelling at the sight as well as... something else. Her hooves jerked, and the building pleasure took shape in her loins building at her shaft’s very tip!

Twilight aimed a careful nudge of magic, spurring Sunset right on the cutie. Sunset bucked as hard as she could, but Sparkle was already spasming around her lost in her own climax.

It was all too much for Sunset and drove her over the edge she hadn't even known was there. The exquisite peek and the spurt thumping through her cock. The tingle both strange, alien and yet immensely satisfying all at once. Sparkle gasped and squirmed on her, prompting a hug from Sunset to cling and ride the afterglow together.

“Pretty good spell as I say so myself,” Twilight remarked, for once not at all sorry to be boastful.

“She… came... inside... me?” asked Sparkle while trying to piece her thoughts through the breathless haze.

“Don't worry, the mess is more for the fun of it than the functional part,” replied Twilight guessing Sparkle's worry.

Sunset started to relax and sighed as the tension too faded from her erection, she’d felt like she had galloped a track. “That's a relief.”

Twilight's horn lit as she continued explaining, “But for the solid bits, those can be refreshed. Instantly, in fact.”

“Mmmhmm that’s nice, wait… what?” Sunset mumbled then cried as Twilight’s bolt of magic struck her. All at once she was eyes open and hooves flailing when stiffness returned with a sudden, aching vengeance. Sparkle rode her a few more strokes before easing herself off and having Twilight taking her place.

Sparkle giggled as she put a hoof across Sunset’s chest and leaned her head on her shoulder. “I need the break, but you don't, apparently.”

Twilight leaned to bump her nose on Sunset’s and murmured, “It’s only your after-birthday party for a few more hours yet. Why spend it sleeping?”

Sunset thought about telling the princess that she was a little bit heavier than her counterpart, but then Twilight was turning and giving her a view of where exactly those extra pounds went.

Twilight peeked under her own body to spy at Sunset’s twitching shaft. “See you agree with me! Part of you, anyway.”

Sunset leaned forward then and clopped her hooves over that broad purple haunch. She pulled Twilight back, ready to charge right in. There was only so much teasing a pony could take!

Twilight rolled her hips and angled herself just right to let Sunset slip in with barely a missed beat. She puffed out happily. “There you go! Good, Sunset.”

Sunset was surprised, but the hot welcome was nice and Twilight breaking into a moan was doubly encouraging as was the swat of her tail against Sunset’s flank to coax her on.

Taking the hint, Sunset squeezed Twilight’s bottom with her hooves and drove upward. It was different with Twilight than it had been with Sparkle. Sunset supposed that was the benefit of experience. Experience, excitement or Twilight having enough foresight to lube herself.

Whichever the reason, Sunset let the second push carry her to the hilt and let out a rowdy snort. Twilight gave her this thing, and Sunset was going to give it back hard! She put her hooves in another squeeze of that purple behind and spanked the side of that Star-cutie with a forehoof.

Twilight’s wings floofed out, and she rolled her hips in a sashay under the spank. She moaned back over her shoulder at Sunset, tail giving a sharp flick backward. Sunset got teased by the tickle of that tail under her nose, and she took a mouthful of it in a firm bite.

With the tough hairs held in her flat teeth, Sunset doubled up on her thrusts. Arching her back and carrying Twilight into the air on every bounce. Making time when she fell back down on her hips all the more succulent. A naughty squish of the shaft driving through and her balls cozy and flush to Twilight’s entrance thrilled Sunset.

Sunset started to feel the familiar build up thumping along that shaft, her pleasure beginning to rise and feeding into her workout thrusts. As Sunset bounced the princess in her lap, Sparkle was intently watching the action with her hoof between her own legs and rubbing at herself. She spotted Sunset looking and put a kiss on the side of Sunset’s tail-full mouth.

The sweetness spurred Sunset on to give another few energetic pumps until she felt Twilight seize upon her in a flutter. Her horn lit and Sunset felt herself held fast inside.

“Now, Sunset!” Twilight exclaimed, horn magic flickering as her concentration wavered.

Sunset squirmed furiously, teetering on the edge of pleasure, yearning for another clench from Twilight’s loins before falling entirely over on the side of release. Sunset groaned, and her head fell back into pillows as she felt the pressure leave her in spurts into that massaging tunnel.

It was Twilight’s turn to climb off with a happy sigh and fall into the bed beside Sunset. The birthday mare had about a half minute of rest with a Twilight in each hoof before Sparkle got up and poised herself.

“Let’s try it pony style!” quipped Sparkle with a waggle of her flanks.

Sunset looked over to Twilight who was already lighting their horn. “I’m moving, I’m moving!” She stumbled out of bed, woozy on her hooves. Celestia help her if she started seeing double, four Twilights would be the end of her.

Dutifully, Sunset approached Sparkle from behind, gently plying at her haunch with a hoof. She leaned in to nuzzle at Sparkle’s muff to kiss and draw a tongue across her cunnylips. This at least she could do without magical aid.

Sparkle swayed on all fours before bracing her hooves. “Nngh! Oh, Sunny. I want you to fuck me!”

Sunset puffed out against Sparkle’s mound, first in surprise from the profanity and then again when Twilight’s spell zapped her into frizzy-maned, hard-dicked readiness. She took time to stick her tongue out at the princess over her shoulder before putting it to the not-princess in front. “Mph! I thought you were worried about being a nerd. When did you become such a sex kitten?”

Sparkle shivered under the tickle and blushed. “I still have desires, even if I'm antisocial. I just didn’t have a person to share them with, until you.”

Sunset smiled at her and put a kiss to the small of Sparkle’s back which coaxed a giggle from her. She continued kissing, making a trail until she was nuzzling the back of Sparkle’s neck. “Still plenty romantic when you want to be, Sparkles.”

Sparkle returned the smile before gasping when Sunset pressed forward and then inside. She quivered on her hooves, nearly stumbling before locking her legs and taking Sunset’s weight.

Sunset puffed a sigh of pleasure in feeling her lover settle around her shaft again. A kinky part of Sunset enjoyed the raunchiness of dipping into Sparkle’s sex still juicy from their previous orgasm. The drizzle of cum made their join all the more heated, and Sunset lingered there, grinding her hips.

Sparkle quivered with the act of being mounted and closed her eyes to revel in the drag of weight on her back. After a few minutes of slow grinding, she peeked back and wiggled her bottom encouragingly. “Mmh, Sunny… giddup?”

Sunset snorted into Sparkle’s mane and nipped her nape for that. “I want to! I’m just finding out that guys who brag about having two girls leave out the exhausting parts,” she admitted.

Sparkle’s brow furrowed before she asked, “Twilight, could you—”

“—already on it!” Twilight answered.

Sunset chuffed. “Your spell already got me plenty stiff. I don’t see how another will do any—hnngh!” Her words were cut short when she was reminded of her femininity all at once. Twilight had hit her not with a spell, but with forward push of her own.

Twilight leaned in and bit at Sunset’s ear to keep her steady, sounding out a muffled grunt when she rocked into place. She had lubed her stalk, and it claimed inches of Sunset’s body in a rush right down to a slap of purple scrotum at the hilt.

For Sunset it was a return of that duality only in the opposite way. The conjured shaft she was using gave sensations, but they were distant and remote when compared to her actual flesh being parted and stroked. How could she have ever forgotten she was a mare?

Sparkle meanwhile cried and suddenly slouched forward, her head between her hooves as she had to take on double the weight on her back.

Sunset hastily braced herself to ease up some of the weight though she was still thoroughly pressed against the back by Twilight and up against the chest and hips by Sparkle underneath. Sunset panted from the new exertion but was aroused by the closeness. Sandwiched between girls! Maybe those braggart guys were onto something after all.

Twilight rolled her hips and started to pump into Sunset’s sex. At first, Sunset took it, rising on her tip-hooves as she felt herself spread open. She tightened on that cock, and the throb inside her tunnel provoked a hard kick from her own shaft inside Sparkle. Apparently, the spell could keep up with switching pleasure in both directions.

Sparkle jolted at having Sunset ticking away inside, with a shaky voice somewhat muffled by her hooves. “H-Hurry, Sunny!”

Sunset got a tweak from Twilight’s lips still holding on her ear, and Sunset passed it along as a kiss on Sparkle’s neck. Afterwards, Sunset relaxed and let Twilight’s strokes carry her forward.

Twilight began humping in earnest. It wasn’t long before her thrusts were hilting on the downstroke with enough force to have her purple sack clap against Sunset’s spread sexlips. The tingle of those balls swatting her clit spurred Sunset forward to drive likewise into Sparkle.

Sparkle responded by rolling her hips upward and bringing the fullness of that wonderfully cushy ass into Sunset’s lap. Bouncing her thighs off those rumpcheeks lifted Sunset enough to set her up for Twilight’s next stroke.

Sunset felt like a part in some wonderfully sensual machine and she closed her eyes. Letting herself fall into the immersion of being rubbed on either side, inside and around by her twin lovers.

It had Sunset in a dreamy state, swinging like a pendulum and barely aware of when Twilight let her ear go and dipped her nose over her shoulder.

“Ngh. Hah… Hah… Almost there, get ready on her,” said Twilight.

Sparkle trembled and nodded, headtop brushing against Sunset’s chin as she replied to her other, “R-Ready!”

Sunset only had a few more beats to have it dawn on her, but by then Twilight was shoving her forward, driving to the very root. It had Sunset gasp and squeeze out of sheer reflex. Her hips jerked and tried to move, but Sparkle was tightening her own loins, keeping Sunset held and trapped. Sunset moaned at being caught and if she still had toes she would be curling them.

Twilight voiced a groan and her shaft inside Sunset bucked as all at once there was a rush of bubbliness. Sunset’s breath caught, once Twilight came inside her, it lit her own fuse. Sunset's cunny milked that spurting shaft while the magical rebound had her release her own pent load in Sparkle underneath.

Eventually, the three of them collapsed, held together like stacked spoons.

“I don't expect anypony to hang around, but they left such a mess,” said Twilight , oblivious to how ruffled and disheveled she herself looked when the three returned to the library.

Sunset grinned and thought she could finally tell her apart now from Sparkle. Although Sparkle was making it easy with how she was keeping herself pressed against Sunset's flank as they walked.

The shameless affection was flattering, but when the mirror came into view, Sunset sighed.

“Something the matter?” Sparkle asked.

“Just thinking how we might have to act on the other side of that. I’m going to miss being able to be sweet on you,” replied Sunset wistfully.

Sparkle eyed the mirror with her, her brow furrowing before she replied, “It doesn’t have to be any different.”

That had Sunset’s ears perk as she looked over. “It’ll be rough you know, people like to whisper...you don’t have to—”

Sparkle interrupted her with a firm kiss before breaking away with a small blush coloring her cheeks. “If something I observed being over here is that if you get too worked up on the what-if, you miss out. Trusting in your friends and opening up with your feelings brings great... experiences.”

As Sunset and Sparkle hugged each other, Twilight smiled. “Another friendship problem solved! If the others were still around I’m sure they’d wish you two well.”

“Well it wasn't fair on them to have us all run off without a word,” said Sparkle pragmatically while giving Sunset a pointed bump with her hoof and making her 'oof' theatrically.

“Not that I think of them as maids or anything, but they— “ Twilight's voice halted when she magically lifted a pile of party favors to reveal a sheet of paper on the table.

Immediately all the objects fell to the floor and Twilight looked pale. “You have to go! We have to go!” she exclaimed.

Sunset and Sparkle shared a nervous glance.

“Is it some kind of magical threat?” asked Sparkle.

“No! Worse!” Twilight cried, raising the paper and turning it for them to see.

Sunset squinted at Pinkie's obvious balloon word mouthwriting. “It’s an invitation to a... a... after after birthday party—” she sucked in a breath, her eyes going to pinpricks as she read the next words. “—at Canterlot High!”
