All Tomorrow's Birthdays: After School Special

Sonata Dusk had made an exciting discovery: Most students at Canterlot High didn’t seem to recognize her.

When she told Adagio about it, Adagio said something about humans being oblivious idiots. Aria said it was probably because Sonata was so forgettable. Sonata thought maybe it had to do with the Friendship Games that the CHS students often yammered about. Apparently, they had been so amazing that no one remembered the battle of the bands that had happened in the months before. Except for maybe RD and her friends.

Still, as long as Sonata was careful to avoid that group, she could sneak in and get the discounted late lunches the school offered for anyone doing after-school activities. They didn’t even check for ID!

Canterlot High also had a pool, but not a swim team. Sonata could get a nearly free snack and then go for a swim right after, usually alone. It pleased her Siren nature just to lay back and float, though it made her human legs cramp for some reason.

“There you are! Ugh, you look like a whale,” Aria called from the edge of the pool.

Sonata opened her eyes and waved, which upended her floating and made her spend some time thrashing upright. She paddled to the edge afterwards, coughing. “H-Hi, Aria.”

Aria made a face and crossed her arms. “Adagio has been looking for you. She says she has something for us. Something impor—augh!” She hastily stepped back to avoid the splash of water Sonata made with her hands.

Sonata giggled. “It’s just water! Why not swim before we go? You remember swimming, don’t you?”

“If I go in there, it’ll be to strangle you.”

Sonata grinned and in a sing-songed, “You’d have to get weeeeet first!” She splashed towards Aria again.

Aria had stopped looking towards Sonata, her attention suddenly drawn to the doorway to the locker rooms. When Sonata’s splash soaked her boots, she gritted her teeth. “Could you stop being stupid for one second?” She paused, realizing the scope of what she asked for and amended, “Just… shut up. Something's going on in there.”

The air felt charged in a strange, yet familiar way. As the two sirens waited, the feeling grew into a tingle that had both of them gasping.

“Aria! Your ears!” cried Sonata before she felt at herself. “My ears too!” She bubbled as she went under when both her hands went up to her head.

Aria reached up to check herself and looked back to Sonata. “Hurry and get dressed! It must be something to do with Equestrian magic.”

Even without a soccer ball being kicked between them, the Rainbows kept up their competition.

A competition that had them barreling into the showers locked in a heady kiss.

RD fumbled over undressing Rainbow, helping her Equestrian self out of her shirt with hands.

Rainbow repaid the favor with her wings, using the flexible tips to fling away articles of clothing.

It surprised RD that Rainbow could pick apart a sport bra with just her wings, though the amazement was cut short when Rainbow rubbed the knuckles of her fist against RD’s bare tit.

“Ow! You better get used to using fingers before we do anything more!”

Rainbow paused and looked at her hand. “Sorry, I keep forgetting.”

RD chuckled. “It’s alright. Here, let me show you.” She led Rainbow the rest of the way to showers, turned on the tap and lathered up her hands with some soap from the dispenser.

Once thoroughly sudsy, RD reached for Rainbow’s front. “Better this way, yeah?” She demonstrated with a thumb around her twin’s breasts, turning her soaping into a caress around the peaks.

Rainbow at first only watched RD work before the touch had her pony ears perking as well as her nipples themselves. “Hmm... that does feel kinda nice,” admitted Rainbow. She took a cue from her human double and imitated the soapy fondle.

RD shivered at the handling of her breasts. Inwardly, she'd always been a little self-conscious, though with a partner of exactly the same size, it was almost... comfortable. She peeked an eye up at Rainbow. “Guess I can teach you something after all.”

Rainbow snorted. “Gonna let me score this time?”

“That’s as bad of a pun from Pinkie.”

Both Rainbows fell silent as their hands wandered and touched each other. There was a kind of kinkiness in being pressed up against a mirror image one could feel. What started as mutual washing soon grew into more as one Rainbow would cross a nipple or pet over a curve. The other Rainbow would up the ante with an even bolder touch, bringing their teasing to the forefront.

Finally, Rainbow leaned close and nuzzled RD’s ear. “I got something I can show you, though.” She moved her arms around RD’s waist and brought her wings low in a scooping motion.

RD flailed as she was lifted. She quickly put arms around Rainbow’s neck and her legs around their waist as she found herself carried. “Whoa! They are that strong? Like, they don’t tear?”

“They are like hands, but better! You really should use yours more.” Rainbow emphasized her point with a squeeze to RD’s rump with those cupping feathers. RD squirmed from the extra limb’s touch.

Rainbow pressed on, propping RD up against the tile wall of the shower and moved in to aggressively kiss.

RD's quietly moaned, with the water coming on them both she was trapped between taking her breath mid-kiss from her twin. Rainbow looked to have had the upper hand, or in this case, wing.

Not gonna let her win this one without a fight!

RD fumbled behind her and aimed the shower head at Rainbow’s face.

Rainbow broke the kiss and sputtered, her wings letting go of RD to shield herself from the water. “That’s a bad trick!” Rainbow complained.

RD grabbed at Rainbow, spinning her about to come at her from behind in a spooning hug. “All’s fair in love and war and all that. Heh, lemme show you what fingers can really do.”

As she spoke, RD put a hand under Rainbow’s arm to feel at her breast while at the same time drawing her other hand around Rainbow’s hip to run fingers through her multi-colored muff.

Rainbow fidgeted after this table flipping, unable to flap with her wings pressed flat by RD’s warm body against her back. RD perched her head on Rainbow’s shoulder and grinned at her.

“I think you’ll like it, though,” RD replied as her fingers played a slow massage around Rainbow’s sexual hood.

Rainbow tried to bite at RD’s ear, but couldn't reach the ponified location on the top of RD's head.

RD repaid the attempt with a firm pinch on the nipple that had Rainbow exclaim and stiffen up.

Eventually, RD's circular strokes melted her double's fiesty struggles and Rainbow’s hips started rolling to match RD’s palming.

“You… are… pretty good at this,” panted Rainbow, begrudgingly. “Who… before? Applejack?”

RD slowed briefly as she chuckled. “Nah, not her. Fluttershy, mostly.”

Rainbow blinked at that, almost taken out of the mood with the surprise.

“You’re tensing up just like she does. Just relax,” RD murmured while calming with a kiss alongside Rainbow’s neck.

The hot water and general closeness were starting to make the shower steamy. The warmth of it combined with RD’s steady finger work eventually brought a coziness that made Rainbow sigh and close her eyes.

A tickle of feathers prompted Rainbow to open her eyes again. RD had brought her wings around and used them to hug at Rainbow’s breasts while her hands played below.

“Quick learner! I guess...ngh... I can let you win... this one,” muttered Rainbow, flustered with both the admission and building arousal.

RD chuffed at that and amped up her rhythm, working a finger in a curl into Rainbow’s tunnel.

Rainbow expected it and widened her stance to better ride RD’s hand. Though for all her efforts at trying to keep it cool, Rainbow’s legs started to tremble.

RD zeroed in on that spot in her and coaxed fingers across it while also leaning against Rainbow’s back. Their identical bodies made the spooning a snug fit.

Rainbow in the past had only felt tongues get as close to the spot the fingers now danced across. Her new appreciation for them came out in a loud moan and a sharp bucking her hip. The pangs of pleasure turning into a tumbling orgasm.

RD pressed in close, letting Rainbow’s provoked rocking continue to rub herself out on RD’s wrist. Though she couldn’t help herself a nibble on Rainbow’s ear and a smug whisper, “I got the goal this time.”

Rainbow groaned.

When it seemed like the Rainbows were winding down, Aria grabbed Sonata’s wrist and pulled her away from their hiding spot in the locker room.

Sonata made a quiet yelp at the tug and stumbled behind Aria as she was reluctantly dragged down the hallway.

Aria turned to her once they were far enough away to not be overheard. “Did you see that?! That was Rainbow Dash with her Equestrian double!”

“Yeah!” exclaimed Sonata with wide eyes.

Aria paced as she mused, “They came through the portal, somehow, but it couldn’t have opened again so soon, could it?”

“Yeah,” agreed Sonata now with a furrow at the brow.

“But… she’s here, and she brought magic with her. We've got a chance to get it again! We just have to do what they did.”

“Yeah?” asked Sonata, doubtfully.

“We have to hurry, there might be a time limit, as soon as possi—umph!” Aria was interrupted by Sonata’s sudden, full-on kiss.

Aria’s shock lasted a few seconds before she glared. “What. Are. You. Doing?” she spoke each word slow and carefully into Sonata’s mouth still pressed to hers.

“Yuh sahd tuh dooh wah teh dideh,” mumbled Sonata, her enthusiastic smile wilting. Aria was going to yell at her, she just knew it.

Aria quelled the urge to bite and turned her head. “I meant the portal! We have to find it and go through it. Let’s go tell Adagio.”

“Oh… okay,” said Sonata, somewhat disappointed.

“And if you tell Adagio about this, I really will strangle you!” Aria warned, finally shoving Sonata away with her cheeks burning a furious shade of purple.

The ‘Scientific Measuring’ had gone as well as expected.

Sunset complained about the judge’s impartiality though Sparkle pointed out that the difference in p-value between the two was relatively minor.

“I can’t believe you can say that bit of statistics with a straight face,” said Sunset, her eyes rolling.

“Oh come on, that was a good one,” argued Twilight in defense of a fellow math nerd.

“I was being serious,” Sparkle said after some glasses adjusting. “Mostly serious. You're easier for me to try oral with, Sunny.” She smiled and added. “Besides, I want to.”

After the contest, or rather ‘study’, Sunset kept sitting on the edge of the tub while Sparkle knelt on the bath rug. Twilight helped her Earth self out of her clothing and took a position behind her afterward. They moved wordlessly, as if they had planned it out beforehand somehow.

“I used to think I needed to be a big sis protector around you, but I’m starting to think you’re far more adventurous and kinkier than you let on,” noted Sunset, watching the two Twilights settle in and embrace.

Sparkle shared a kiss with Twilight over her shoulder before breaking it at Sunset’s statement. “Kinky how?” Her tone was genuine, even as she moved forward and laid her cheek against Sunset’s thigh.

Sunset looked at the two and then scratched her own cheek. “Ooh... nevermind.” Having Sparkle’s face there in her lap, looking up with those big rimmed glasses. She looked tremendously cute and her body reacted accordingly.

“Well, okay. I have a hypothesis about you too, Sunny.” Carefully, she reached to hold Sunset’s shaft and after a moment kissed the tip. “You like kinky.”

After a small shiver and even bigger twitch, Sunset was about to answer when she looked up to Twilight. Twilight had taken hold of Sparkle’s hips and drawn her body close. The warm sigh in Sunset’s lap made her realize why Twilight was so focused and quiet.

Had it been anyone else Sunset supposed she might have felt a little jealous, but something was thrilling about the idea of one Twilight fucking the other. Figures I’d not only have a Twilight Sparkle fetish, but a Twilight on Sparkle one too.

Even though Sunset didn’t voice the thought, there was plenty of evidence for it now standing upright in her lap. Sparkle nuzzled the side of Sunset’s stiffness, “Bet I’m right, Sunny.”

“You want a cookie, Sparkles?”

“Maybe something a little sweeter,” said Sparkle before touching her tongue to the tip.

“That’s not sweet…” Sunset huffed.

Twilight slowed her thrusting to comment, “Actually, the flavor was one of the first things I changed with the spell.”

Sunset stared at Twilight who smiled broadly back for a response. Sparkle meanwhile drew down and took in several inches of Sunset into her mouth.

For Sunset, owning a penis still felt strange. It seemed to have its own mood, wants and desires. How much of it was magical wire crossing? How much of it was just a dick being a dick?

The separation of sensation helped in some ways when Sparkle started sucking, she was clumsy and rough. Had she done that to Sunset’s clit directly, it’d have made her yelp.

Sunset put a gentle stroke of her fingers against Sparkle’s cheek. “Umm. I’ve found when you’re with a guy, it’s less about the actual sucking and more about moving your tongue around.”

Sparkle gave her a look.

“Hey, I didn’t name it! You aren't even supposed to blow.”

A change came to the tempo, Sparkle becoming more methodical in drawing her tongue around Sunset’s glans. First outlining the shape and beginning a slow stroke along the bottom. Her eyes asked a new question.

“B-Better,” replied Sunset as the tongue motion coaxed her hips into lifting on their own.

Sparkle smiled and closed her eyes, puckering lips and began bobbing her head. She made sure to use her tongue to apply pressure from below with every suck.

Sunset shivered and for a while let Sparkle tease and work her up. Sunset’s hands came to feel and play with Sparkle’s hair, a surge of happiness tingled alongside her building lust. Her Sparkle, there.

Twilight leaned forward then with her own lips raised. Sunset felt a blush come to her cheeks and hesitated.

Sparkle was in an excellent place to feel the slightest change in Sunset’s body tension. She peeked up and winked at her.

Sunset chuckled softly, and she thought she could get used to being apart of this wordless twin dynamic. She moved forward to meet Twilight’s lips with her own.

Even though she had kissed both Twilights in Equestria, kissing them again as a human brought a familiar yet new experience. It also gave Sunset particular joy to be able to finally out-skill Twilight at something as she could run literal circles with her tongue around Twilight’s.

Though despite being able to tip Twilight’s head back with a well-timed press of tongue, Sunset was the one who gasped. Sparkle below had turned her head and found a good angle on Sunset to ramp her sucking pace, her cheek puffing out cutely on the side as her lips squeezed tight.

Sunset’s hands reached again to feel along Sparkle’s hair bun. Petting turned into a grab as the buildup skyrocketed. It was another difference between the human and pony, the sudden desperate need to thrust and get as many thrusts in before the climax.

“Ahh!” Sunset cried, hips lifting and the immediate pleasure as she came, her shaft throbbing out as she spurted. She squeezed and rode the joy of that quivering tightness until the realization struck her that she’d jabbed herself into Sparkle’s mouth and throat.

Sparkle stared up at her, eyes wide and glasses lopsided with her hair bun messy and undone.

“Oh… honey, s-sorry.” With the intensity of the moment now past Sunset felt shameful for grabbing without warning.

Sparkle eyes squinted, and her throat bobbed.

“Wait! You don’t have to do that!” Sunset exclaimed. A new blush rose along with a fresh pang of guilt.

Sparkle pulled off at last and coughed. “Aren’t you supposed to? I didn’t want to spit and make you think—”

Sunset groaned. “Don’t feel that way, that’s just something that guys like to put over girls.”

Sparkle made a shaky smile. “It wasn’t so terrible. It was still, umm… sweet.”

Twilight moved her head in close to Sparkle’s. “It still worked here? Let me have a taste.”

Sunset held her burning face in her hands as the two Twilights shared an another, now messy, kiss.

Eventually, Sunset peeked between her fingers.

Gonna make you smile and brighten up your day—

Spike shoved his muzzle under a pillow. It was the third time he’d heard that song. The first time it didn’t wake him until the last lyric. The second time he’d held out hope that Twilight would answer it at some point. Now that it started up again it left him little choice but to amble off the bed and over to the dresser.

Once he got to the ringing phone, Spike looked between his dog paws and the flat rectangle of glass. He couldn’t quite remember when the humans stopped putting buttons on these things but found it damned annoying.

A few swipes with his paw knocked the phone off the dresser, but it still sang Pinkie’s song. He tried with his nose to press on the screen but ended up pushing the phone underneath the table instead.

All I really need’s a smile, smile, smile

Spike barked his frustration. Just where was Twilight anyway?

Twilight started to stand and pull herself free.

Sparkle took a breath at the feeling of that shaft’s withdrawal before looking back. “W-Wait, you didn’t finish...”

Twilight inclined her head, and with Sparkle, both took a look at the purple erection still jutting forward.

From Sunset’s perspective, it looked like they were working out a math problem.

Sparkle smiled after a moment and suggested, “Could try it a bit rougher?”

“Ha! I knew you’d say that,” Twilight said, happily.

Sparkle giggled then looked at Sunset. “Sunny, hold me while she goes for it?”

“Umm… sure,” said Sunset as she laid back and hugged Sparkle around her middle. “Rough, eh?”

“If you kept notes, you'd be less surprised,” said Sparkle with a grin that looked rather wild. The expression helped by her askew glasses and tousled hair sprung around her hair bun.

Sunset reached to straighten Sparkle’s glasses for her. “I guess you really do have to watch out for the quiet, nerdy ones.

Twilight briefly went to the countertop to fetch the bottle of lube. Her approach with her flesh glistening had Sparkle shiver and turn to tuck her face against Sunset’s throat.

“You seem pretty experienced with that,” Sunset said to Twilight over Sparkle’s shoulder. “I wasn’t the first you tried that spell on?”

“I wouldn’t use magic on somepony that I hadn’t thoroughly tested on myself first,” said Twilight before she laughed, realizing how apt that statement was now.

Sparkle chuffled at the wordplay and wagged her bottom under Twilight’s poised stiffness.

Twilight swatted the side of that swaying backside and then held it with a squeeze, holding Sparkle ready for the forward press.

True to Twilight’s word the second penetration was a strong push that soon had Sparkle crying out. “Ngh!” She shook, threatening to fall to one side until Sunset held her hands, lacing fingers in a tight clutch to keep her on top.

The added grip helped keep Sparkle on target and have each time she rocked forward to drag her breasts in a sliding and steady rub over Sunset’s own bust. Their nipples perked and aching under the constant glancing touch.

Twilight for her part murmured and stroked fingers along Sparkle’s back. Scientific and sexual curiosity had long since overpowered any sense of weirdness of having sex with her mirror twin. There was also a strange kind of vanity and smug satisfaction in admiring Sparkle’s plush bottom when it shored up against Twilight’s hip.

Being in control also added a kind of spice. Feeling her other self’s body react with little moans here, a tremble of body there. It fueled Twilight’s enthusiasm for the next thrust, and then the next one after. She was eager to hear Sparkle catch her breath and be pleasured by her shaft. To know that she was in command, so thoroughly, well... Twilight thought she could get used to being a dom.

When Sparkle’s tunnel gave a short, clenching spasm around Twilight’s shaft, it banished the rest of any thoughtful musings. Twilight leaned forward and threw her weight behind her thrusts, feeling that building, urgent sensation gathering at her cockhead.

Sparkle pushed her face underneath Sunset’s chin, and her trembles grew. “Ah… ahh! Su-Sunny, I… sh… she’s going to cum… oh! She’s coming!” Sparkle’s dreamy look changed to a wide-eyed surprise and then a shriek. “She’s coming!?!”

Sunset had been enjoying the act vicariously through the steady body on body contact with Sparkle. With her eyes closed, Sunset could just about feel Sparkle’s excited heartbeat pound in her chest. Sunset felt oh-so-hot all over from the intimacy of it all… at least she did until that cry had her open her eyes.

A pair of ponified human faces stared back.

“Wha—” Sunset started to say before she felt her own ear twitch. Her now pony ear. “—oh… oh! Sparkles, are you okay?”

Sparkle gave a small, restrained nod. “As… as long as she... d-doesn’t move. It doesn’t hurt. Just... surprising—”

Twilight took measured breaths and spoke in between them. “—and tight! B-but, look at yourself, Sunset.”

Sunset glanced over at the mirror and blinked. She’d ponied up plenty of times before, but this time her hair flowed in a very Celestia-like drift and what she had taken for sexual warmth had actually been the glowing traces of light around her shoulders and forehead. As she watched, the radiant effects faded and she returned to her usual ponygirl self instead of her angelic version.

“You are so beautiful, Sunny,” Sparkle murmured.

Sunset reached to tickle Sparkle’s floofed out wings. “So are you, sweetie.”

“Hmm, I guess it had something to do with our…err, moment together, “ Twilight said with a small waggle of her wings.

Sparkle made a likewise waggle of her bottom still wed to Twilight’s lap. “But only Sunny became more than just a pony? I didn’t… turn into…that nightmare...”

Sunset leaned in to nuzzle at Sparkle’s shoulder. “Maybe positive energy makes a difference?” She speculated on the idea briefly before pausing to look in between them. “Are… are you two stuck together?”

“She’s still too hard!”

“She’s still too tight!”

Twilight and Sparkle both flustered as their reply to Sunset came simultaneously. “Well you are!” They echoed next before making identical tongue sticks at each other.

Sunset giggled.

A voice called from the other side of the bathroom door. “Hey, Twilight! The phone’s ringing!”

The interruption had the trio turn still like statues.

Sparkle recognized the voice and answered, “Let it go to voicemail, Spike! I’m in the bathroom.”

“Well okay, but it’s from Pinkie, and it already rang twice.”

There was a pause followed by a scratching sound as canine Spike pawed at the door. “Rwfnf?… is there someone else in there?”

“Just me and Twilight in here, Spike,” Sunset said after a nervous glance passed between them. It wasn’t a lie, not exactly.

“Oh! Hi, Sunset! Uhh… why are you both in there?”

Sparkle stared with amazement as Sunset’s ponified shaft started to lift and erect. She looked up and mouthed. ‘Really?’

Sunset made an embarrassed shrug, looking less angelic with every throbbing heartbeat. “Umm... Girl Stuff!” she called back to Spike.

Twilight clapped both hands over her mouth and shook with contained laughter.

“Rrr-Okay. But you better not complain about the phone if it fell off the dresser or something. I’ve been trying to nap.” Spike grumbled.

The sound of departing pawsteps had the three sagging in relief... most parts of them anyway.
