All Tomorrow's Birthdays: After School Special

Twilight watched the rest of the girls get into the rhythm of their get togethers with mixed feelings. She hadn't planned on any of this, but she couldn’t argue with results. Pinkie Pie’s party, for all its chaos, seemed to have worked out as usual… somehow.

Personally, Twilight preferred more structure to her sexual explorations.

Adagio started to get up but was stopped by Twilight’s hand pressing a palm on her forehead.

Frowning, Adagio pushed against that hand but only succeeded in wobbling on the ground. She cried, “How are you doing that?!”

“Center of gravity. It’s a quirk of human anatomical motion,” Twilight explained with a wink. “I studied up on it after a day of flailing about.”

Adagio tried to scoot back only to find Twilight’s hand gripping her instead. Like Twilight’s earlier punch the grasp was unexpectedly strong.

“Though the alicorn strength helps too,” Twilight continued to explain.

“Ali—what? I thought you were a pony?” Adagio asked while reaching up to pull on Twilight’s wrist.

Twilight blinked and raised her other hand to her chin while Adagio continued to squirm. “Yes I am, but… you don’t know about alicorns? Ah, that’s right! It was Starswirl who banished you, before the sisters even.”

With a shrug, Twilight turned towards Adagio and unfurled her wings. “Well then! I guess I should introduce myself properly. I'm Princess Twilight Sparkle.”

Adagio finally stopped struggling and just stared up at her. “Really,” she deadpanned. “A princess? You?”

“For realsies,” Twilight said with a genuine grin. “One of the four Rulers of Equestria and the Element of Magic. Though I’m known more for being the Princess of Friendship.” After a small beat, she added, “I even have a castle.”

Adagio mouth worked, struck speechless and unnerved by Twilight’s apparent honesty. Eventually, she stammered, “Y-You are serious. You’re actually serious.”

Twilight turned her grip on Adagio into a gentle petting along the cheek. “Absolutely. I fix relationship problems and those with problems.” Her fingers trailed along Adagio’s jaw as she admired the siren’s full lips.

“Umm,” Adagio said, briefly looking away at the cheek touch and unsure before glancing back to Twilight. “What are yo—” her sentence was interrupted by the sight of Twilight undressing.

Twilight sighed as she stepped out of her pants. They were better than the panties and skirts, but still not made with ponygirls in mind. Teasing Adagio had left her feeling chafed, and she now bobbed freely out in the open.

Adagio looked on with wide eyes. “Are all alicorns like… that?”

“Oh, kind of... alicorns embody all the traits and magic of ponykind,” said Twilight before giggling. “As for this… well… it’s more fun than getting blasted with magic again, hmm?”

That shook Adagio out of her intimidated state, and she couldn’t help a groan openly. “That’s a terrible joke. You’re terr— hmmph!”

Twilight made a pleased snort as she quieted Adagio with guiding touch on the head and a thrust of her hip forward. “They also call me the Princess of Lecturing. Maybe they are right? Enough talking, we both need to save our breath… especially you.”

Adagio mumbled around her mouthful, eyes rolling until Twilight goaded her with another half-thrust.

“Remember, you have to stay positive if you want to transform. Work with me, Adagio.” Twilight reminded.

This experiment in domination was becoming fun.

After some adjustments in Twilight’s position and Adagio’s posture, Twilight started to build a rhythm. As she suspected, Adagio was a bully, but like most bullies, a firm hoof put them in their place. A good thing too, as Twilight lost some of her objectivity as she indulged.

Twilight first thought to move slow, well aware of the tight press of her ponified shaft past those sucking lips. She ought not to have bothered, as she found Adagio lifting her head readily to meet the push of Twilight’s flesh and swallow the extra inches without a hitch.

Hmph, she’s a singer and a siren. I guess she really does have good breath control.

Twilight peeked down, and Adagio looked back plainly. She knelt with her back straight, hands folded in her lap, the very picture of an obedient girl with a book-on-her-head posture. Twilight caught the challenging gleam in those raspberry eyes and the smirk on the lips around her shaft’s middle.

Well if you're going to play it like that…

Twilight coaxed a few fingers into that great mass of hair, before digging in a good grip and rocketing up the pace and depth of her thrusts.

Adagio’s eyes went wide then squinted shut as she swallowed hard while pushing up her tongue against the underside of Twilight’s shaft. The threat of a gag fluttered through her throat, but she quelled the reflex. It allowed Twilight to slip in deep until Adagio’s lips were nearly at her cock’s root.

Twilight murmured, “There’s a good hippocampus.” She laughed when the use of that olden name provoked a surprised snuffle from Adagio against her belly. “That’s right. I know all about you,” Twilight said to Adagio’s unasked question. “But show me that you fit that legend.”

The warm squeeze of cheek and throat muscle that pressed around her cock next made Twilight’s wings flare out with pleasure. While below her shaft thumped with the uptick of her pulse, twitching hotly in Adagio’s throat. She rewarded Adagio with another thrust that rocked her sack in a sound slap against Adagio’s chin.

To Adagio's credit, she maintained her poise and position incredibly well, though her hands did eventually rise from her lap and grip tight onto Twilight's thighs to keep herself steady, eventually climbing higher to grip Twilight's bottom and give it a firm squeeze.

Twilight’s wings flapped and she worked a firm, hearty thrust that smooshed Adagio’s face flat against her lap. She held the posture, grinding with her sack pushed flush to the siren’s face. When she started to pull back, Adagio made a groan and squeezed hard with lips, throat, and press of tongue.

“Hmmf. If… you… nghh…think...” Twilight’s voice trailed off, interrupted by her loins panging with pleasure in both her shaft and in the link with her clit. Candle twice as bright, half as long. She thought giddily before the finish came with the flare in her shaft’s glans, the hoist of her balls and the rush of cum thudding along that dick.

Adagio gave an ‘uph!’ noise underneath, her eyes squinting as she tried to keep up, only to have cummy excess spill from the corner of her lips. The expression of her preemptive flinch changing instead to a confused look as her tongue savoured the actual taste of Twilight.

Twilight laughed between her panting. “Hah...ah… I hope you have a sweet tooth...”

Sunset looked about the active gathering with a measure of wonder. “All of this, just because it was my birthday… what, two days ago?”

Sparkle giggled. “Hey, I didn’t set this part up. I just wanted us to visit Equestria for cake.”

“Everyone and everypony are getting a slice of something alright,” Sunset noted with a silly grin. With so many of the girls from both worlds in alternating throes of pleasure, the air hung heavy with surges of Equestrian magic. All of their ponified features had become more pronounced as well as their sensitivity to touches, smells, and general attitudes. Sunset wondered if that had to do with a pony’s communal herd instincts compared to humans.

Though, Sunset was already disinclined to analyze too deep into pony/human psychology. Not just because she wasn’t a Twilight Sparkle, but because her Sparkles had a hand busy working the length of her shaft. They had kept to themselves, for the most part, playing voyeur to the rest, and that suited Sunset just fine.

There was something lewdly romantic about being fondled at a slow and steady pace. A simmering kind of intimacy that Sunset repaid with a gentle fingering at Sparkle’s muff.

Sparkle shifted and straightened up slightly. “You know… you should go over to her.”

“Mmm?” Sunset peeked and smiled to herself. She was starting to be able to tell when Sparkle felt a little wild.

Sparkle gave Sunset’s cock a firmer tug before pointing with it to draw Sunset’s eye to where Twilight and Adagio were.

At a distance she saw that Adagio had sprouted her ears and fins again, but was still legged. Twilight looked to be marshaling her into a doggie-style position.

Sparkle grinned and bumped Sunset. “Twilight. She isn’t looking behind her. You can go right up.”

Sunset snorted a laugh. “Bit of a surprise for her, eh?”

“She did it to you in Equestria. Turnabout’s fair play.”

“And what about you?”

“I’ll watch.”

Sunset didn’t bother denying her interest in the idea, not with Sparkle’s hand on her dick being the ultimate truth-telling gauge. After sharing a glance and a brief kiss with one Sparkle, she stood up and headed towards the second.

Twilight was focused on gripping Adagio’s hips and lining herself up. Sunset smirked at the sight and waited until Twilight leaned forward.

From behind, Sunset followed Twilight’s lean with one of her own, slipping a hand under Twilight’s arm to take hold of her breast from the side. With her other hand, she aimed her shaft and tucked in the cockhead and several inches into Twilight’s sex.

That earned Sunset a faceful of feathers as Twilight’s wings spread on reflex. “S-Sunset?” she gasped.

Sunset wiggled her nose, holding back a sneeze. “Gotcha, princess.”

Twilight rocked from one foot to the other, bouncing on tiptoes —and on Sunset’s cocktip— before she relaxed and slowly let Sunset pull her into a standing spoon.

Both of them trembled slightly from the join, Twilight from the stiffness inside and Sunset from the feel of that very royal backside fitted snugly in her lap.

Twilight’s eyes drifted over to her voyeuristic counterpart. “I wonder who put you up to this. Though to be fair, I did do this to you in—” Twilight made gasped again as Sunset pinched at her nipple. “—and you know that twice over, right.”

Sunset grinned. “I’m getting used to having two of you being this intimate and open.”

Twilight rolled her eyes but smiled. “Anyway, I guess I should lean forward and let you push...”

Adagio squirmed, still on her hands and knees. “Do I get any say in this? I’ve been waiting forev— ah!”

Twilight’s hand came down hard on the side of that rumpcheek, giving Adagio a full palm’s worth of a spank that left the siren-girl fluttering her fins.

“No,” Twilight informed her.

Adagio’s face blushed as red as her bottom, but she kept quiet. She still squirmed, however, when Twilight tugged the spiked hairband out of her hair and nuzzled in.

Sunset followed the motion forward, settling against Twilight’s feathered shoulders. With both of them transformed, Sunset didn’t have any qualms about holding back. Twilight’s previous orgasm made it an easy press, and Sunset soon murmured her pleasure into Twilight's shoulder at the hugging warmth.

Twilight rolled her body underneath Sunset’s, carrying the thrust into Adagio below her. Her own satisfaction coming when she felt Adagio tremble and clench in response.

It wasn’t long before a rhythm started to develop with Sunset and Twilight moving in tandem for the start of the swing while Adagio took the brunt of it. A solid, ‘wump’ accompanied each thrust as Sunset’s thighs met Twilight’s curvy rear while Twilight herself bounced off Adagio’s more perky behind.

Twilight finally navigated enough of that orange hair to find the back of Adagio’s neck, placing a kiss there, and smiling when she felt Adagio’s fins rustle in response.

Adagio lifted her head to look at Twilight over her shoulder, hesitant, until a few more thrusts battered down her resistance and softened her haughty expression. Twilight brought her own face in close before she could shy away.

Navigating the siren’s mouth was like her personality. Prickly at first with the threat of those fangs, but once she had passed them, it didn't take much to coax Adagio's tongue into sharing the kiss. Twilight relaxed her hips and let Sunset drive her forward, keeping the tempo throughout the kiss. Eventually, Adagio trembled and moaned outright into Twilight’s mouth.

Sensing victory, Twilight clenched on Sunset and took over for thrusting, pressing her advantage in both the literal and figurative sense. Feeling Adagio shiver beneath her was unexpectedly pleasant, and while the domination play had started off as an experiment, Twilight found the feeling of control quite enjoyable.

Hmph. One more fetish for the list.

Sunset was happy enough to fall into the role of support. It was thrilling enough to watch Twilight and Adagio progress from a kiss to a full-fledged make out. The warm sway of Twilight’s body underneath her and the increase in tension as the girls got excited brought Sunset her own tactile pleasure. That and knowledge that Sparkle watched them encouraged her to widen up her stance, and make sure she gave a blatant show by swinging her hips high like a pendulum. Each succulent thrust forward gave her a squeeze around her shaft and a loud slap of her hip against Twilight’s raised rear. Oh, Sparkles. You’ve turned me into an exhibitionist! Sunset thought giddily.

Adagio never could have imagined at the start of her day that she’d be ending it being piled on by two pony-girls. Shifting in posture, pushing her weight one way, thrusting the other. It made a quirky feeling of being trapped, yet… handled. The absolute attention pleased her diva sensibilities, while the deep touch of Twilight’s ponified shaft scratched an aching itch of her lost natural shape. Is… is this why Aria likes to submit? Oh… abyss, am I a sub-?.

The worried thought was interrupted by a hard lurch forward by Twilight, her mouth breaking away from Adagio’s to groan out. Adagio choked back her own gasp when she felt that full, final stroke. Her clit getting pressed down and rubbed on by the girthy as it slotted into her followed by the pillowed swat of balls going flush. A moment later there was a secondary bounce when Sunset hilted in Twilight. The familiar surge of Equestrian magic started to spread moments before the hot, physical flush of cum bubbling away.

“Oah-oohah!” Adagio sang as she orgasmed, her voice becoming a melodic warble that had her pendant flaring in brilliance. The sound brought a feeling of euphoria that had Twilight and Sunset peaking and having an encore to their duet.

By the time Twilight walked over to the pegasus’ corner, both Fluttershies had ponied up with their wings. She had trouble picking out which Fluttershy or Rainbow was which as they had arranged themselves in a communal four-way square.

A small laugh came from Twilight as all four pega-girls startled like a flock of birds with four pairs of wings ruffling up. “Sorry! I didn’t mean to interrupt. I just wanted to bring you one reformed siren.”

“Reformed?” Adagio asked dubiously, she had regained her finned mer-form and Twilight pulled her floating self along like a kite. Adagio felt little giddy from the transformation, though this label sobered her some.

Twilight eyed her. “Are you going to need even more work?”

“N-No,” Adagio said with a nervous look.

Twilight waited, brow slightly arched.

“No, princess.”

Twilight smiled and turned back towards the Fluttershies. “Good! You should have no trouble apologizing, then. I also want you to just spend some time with them too. All my friends are wonderful. Is that alright with you, Fluttershy? Erm...both of you?"

Fluttershy shared a glance with Flutter then gave Adagio an appraising look. “If she promises to be nice.”

“Cross my heart?” Adagio suggested, making the motion with her free hand, though Twilight kept a hold on her other wrist and stopped her from crossing fingers.

Flutter giggled. “Good enough for me.”

Meanwhile, the Rainbows had been peeking at Twilight and conspiring amongst each other in low whispers before RD plainly said, out loud, “But jeez she’s hung like a horse! Or pony, whatever.”

Twilight perked an ear and looked over at the two. “There a problem over there?”

Rainbow snorted to RD. “Don’t be a wimp,” she said before turning to Twilight with a smile. “We couldn’t help noticing you walking around with a little extra.”

Twilight shifted her stance, resting a hand on her hip as she presented herself in a showy jut. “Careful about teasing me, Rainbow. There might be… consequences.”

RD whistled in admiration. “Wow, our Sparkle over here is kinda shy by comparison.”

Rainbow rolled her eyes. “Eggheads amirite?”

Twilight raised her brow. She was getting a lot of mileage in borrowing Applejack expressions today.

Rainbow tried to think of a good way to ask before she simply shrugged. “Let’s try doing it in the air, Twi.”

Twilight blinked. “Pardon?”

RD made an impish grin. “You got the wings and uhh, cock for it. Nothing quite like that over here.”

Rainbow continued. “Yeah, and it’d be like… double the fun. Isn’t that a princess saying?”

Twilight’s skeptical expression turned into a contemplative one as she tapped her chin. “Sure you two have the stamina for that?”

The Rainbows shared another look, and with a twin grin, came up on either side of Twilight to grab her arms. With a yelp from the princess, the trio took off into the air, leaving Adagio and the Fluttershies staring after the ascending girls.

“Did...did I just get traded for a pair of Rainbows?” Adagio asked, unsure if she should feel indignant at the turn of events or the exchange rate.

Fluttershy leaned over and placed a gentle finger on Adagio’s lips. She looked apologetic. “Umm… pets don’t talk,” she murmured. Meanwhile, Flutters touched over Adagio’s backfins and set the siren to squirming in place, her face reddening.

Her first impulse was to protest or give them both a glare. Her, Adagio Dazzle, a pet? The thought was enough to rankle, but then Fluttershy began finger-combing Adagio’s loose hair, and Flutter’s hands kneaded their way down to her mer-tail. Compared to all the action Twilight gave her before, the Fluttershies were so… soft and gentle.

Seductive.

Adagio blinked with that realization, and she flexed her lower half under Flutter’s massage. Begrudgingly she looked to Fluttershy with admiration. “You… are surprisingly good at this—”

“Shhhhh,” Fluttershy said, leaning in close before replacing her hushing finger with her lips. She continued her hair stroking, running fingers around Adagio’s upright ears while her tongue began to work. Adagio just looked back into those open, seemingly innocent eyes, a small purr, coaxed by the pegasus pair, escaping her throat.

“You know, we live interesting lives,” Sunset remarked as she cuddled with Sparkle at the edge of the stage.

Sparkle lifted her head enough to rub her hair bun against Sunset’s chin. “I suppose we don’t have to worry about what our friends think of us. Not after this.”

You think?” Sunset answered, wryly. “Nothing like an interdimensional party to put things in perspective.” After a moment, she leaned down to kiss Sparkle on the lips. “Thanks for putting up with me being dense, Sparkles.”

Sparkle giggled and raised up to kiss Sunset. “Thanks for coaxing me out of my insecurities, Sunny.”

Sunset smiled at her before a thought made her brow furrow.

“Who’s going to clean all of this up?”
