Twilight stepped up for Cozy Glow after her attempted coup, volunteering to take the filly in and help her see the light, sparing her from Tartarus, and she does so purely out of the goodness of her own heart... Yep, no other reason what so ever.

As Luna prepared to sentence a foal to Tartarus, Twilight Sparkle stepped forward to offer a different solution.

What Cozy Glow did was wrong, yes, but surely a young filly deserves a second chance, and Twilight would make Cozy's reformation her personal responsibility. After all, doesn't Twilight owe her former best student that much? It's the least she can do for the filly who had helped her so much in the past as her assistant.

There's surely no ulterior motive at work, and what the Princess of Friendship and her new ward do up in that castle all day, away from prying eyes, is nothing but innocent. Why, Twilight's productivity as a princess has only increased, and she seems so much more relaxed.

Cozy must not be causing a lick of trouble, even if Twilight is strangely secretive of just what the two get up to all day.

Ponies trust Twilight Sparkle to handle the situation, but it is hard not to wonder what goes on behind closed doors.

If only they knew...

Content warning: foalcon, fillydom, lesbian sex, and, less obviously, surprise wholesomeness(?).

Cozy Glow is actually an 18+ mare with systemic equine hypoplasia, a condition that stopped her body from physically aging. She's just pulling the wool over Twilight's eyes because she thinks it's fun. Yep, that right, it's definitely not real foalcon. Nothing offensive here, folks.

Fun on the New Royal "Throne"

Twilight enters her castle with a tired sigh. Ever since Cozy Glow nearly drained all magic from Equestria, she's been being hounded by everyone from media to concerned citizens. Mostly because, instead of locking the filly up where she could do no more harm, she she has been living in the Castle of Friendship under Twilight's care. She always said the same thing to their concerns, that Cozy Glow is just a foal who doesn't understand how dire the consequences of her actions would have been and that she simply needs patience and understanding to help her see the error of her ways.

At least in that, Twilight was right.

After going over all the ways that removing magic would destroy Equestria from wild weather to major crop failings and the loss of many magically performed medical procedures, Cozy begrudgingly admitted that her plan to rule Equestria was rash and ill-thought out. It even drove the filly to start studying intensely day in and out. Apparently, despite having an innate genius intellect, the filly lacked many academic resources growing up, and being made aware of just how vast her ignorance was had Cozy devouring Twilight's extensive collection of books. In that regard, Twilight is truly proud of her former assistant, and happy to see the filly focused on bettering herself instead of taking over Equestria.

Well, there's a particular caveat to that latter point as Cozy frequently says her new position of power has become far more satisfying than Empress of a dead land could ever have been. That being-

"Golly, Twilight, are you alright?"

Twilight blinks before blushing and staring down at the filly before her, as cute as ever with her meticulously brushed pink coat and perfectly curled cornflower blue mane. "W-what do you mean?"

"Well, you've been spacing out there for nearly two whole minutes. Even worse, I've been standing here in front of you the whole time, and you haven't given the proper greeting."

"O-oh, I'm sorry Coz-"

"Ahm."

"I'm sorry... Mistress, I just had a lot on my mind."

"I don't know what could be distracting you, considering the only thing that should be on your mind is serving me. Speaking of..."

The filly puts a hoof forward, and with a blush, Twilight slowly kneels down and kisses it. She's so glad she's sent Spike to stay with the Apples so he doesn't have to see this. The excuse that she didn't want Spike around Cozy Glow until she was positive she wasn't dangerous convinced her friends well enough.

"Good girl," Cozy says, a smile clear in her voice. "You know, nearly a month of this, and it still brings back fond memories of school. Back when I was your special assistant helping you... relieve stress." Twilight flinches, but keeps her head lowered and eyes on the hoof before her. "Mmm, good, maybe you don't need remedial training. Rise."

Twilight does as commanded, staring at the filly's smug grin with a tight expression. While she tries to keep her feelings off her face, her other end is another story, and she can feel herself winking against her tail. "Quite a few documents came in while you were gone. How about we head to my office so that I can review them?"

Twilight knows it's not a question. "Yes, Mistress..."

"While nature preservation is not without merit, we must make use of all of our kingdom's resources if we wish to maintain our edge over the Minotaur Kingdom, who's industrial advancements in recent decades have put them well on their way to overtaking us as the world's most influential nation," Cozy says as she lays on her back. "Mmph, and that's why I, Princess Twilight Sparkle, rule in favor of Mine Shaft over Green Deal in this dispute over land holdings. However, Green Deal will be overseeing Mine Shaft's operations to ensure they are performed with the minimum amount of damage possible to the surrounding environment while still producing the resources our Kingdom needs to remain at the forefront of the world's economic stage. "

As she finishes, Cozy suppresses a shudder, watching the quill and parchment held in magenta magic ink out her words while Twilight works between the filly's hind legs. The young princess never thought her skills in multitasking would be put to use like this. "Oh, golly yes, that's it. You're getting really good at this, you alicorn slut," Cozy comments as her thighs squeeze around Twilight's head and her winking fillyhood spasms. Twilight instinctively seals her lips completely around the small pussy just in time to swallow down the squirt of sweet, peach-flavored nectar before it could spill unto her mistress' desk.

AKA her own royal bed.

"That should do for that document, I think," Cozy says as if she didn't just orgasm into a princess' mouth. "Just put your signature on it and send it off, and we can get to work on the next one." Twilight pulls her head up, muzzle wet with Cozy's fluids, and brings the document closer, checking over her spelling to make sure she didn't make any mistakes dictating for her mistress. Once she's satisfied, she signs her signature and sends the letter away with a pop of short ranged teleportation. Spike will send it via dragon fire to the correct place.

"You know, you should feel lucky," Cozy says as she pants lightly and lays her head back against the pillow. "I handle all of that pesky thinking that made ruling so stressful for you, and all you've got to do is what I tell you to. I'm almost envious. Aren't you grateful?"

"Of course, Mistress."

"Tell me," Cozy suddenly says, voice taking on a commanding edge. "Tell me how much you love being my slave."

"I... I love it so much, Mistress."

"What do you love about it?"

Twilight's face turns red as she squirms where she lays at the base of the bed, wings ruffling at her sides. "I love... not having to think of ways to turn down all those ridiculous requests from nobles. You always know just how to say no without actually sounding like you're denying them. I love how you've taught me how to cook for you; I still can't believe how much trouble I used to have around a stove before you made things seem so obvious. I... l love that I get to service you." She swallows as a hoof comes to rub gently on Cozy's inner thigh. "Your body is so perfect and sweet. Your smell, a-and taste."

"Golly, you sure know how to butter a filly up," Cozy says with a sweet giggle and light blush of her own. "You're such an honest mare. Applejack would be proud. Maybe we should tell her?"

Twilight's shoulders tense, but she gives a shallow nod all the same. "If that's what you want, Mistress."

Cozy stares at her for a few seconds, then grins. "Good, Slave. You've just earned yourself a reward."

Twilight's heart begins to thunder in her chest, her wings extending partway. "D-do you mean...?"

"Yes, come up here and lay back."

Twilight has to fight the urge to scramble into place, instead waiting while Cozy moves aside at a leisurely pace and gestures for the alicorn to take her place, which she does with barely contained excitement. Her tail flags as she shimmies forward on her belly, and she yelps as she feels a sharp tug that pulls loose a few strands. Looking back, Cozy is grinning wickedly around the hair between her teeth as she eyes the sopping wet, purple pussy revealed to her, strands of thick arousal stretched between her tail and her winking folds.

Spitting the tail from her mouth, Cozy says with a giggle,"Gee, Twilight, I haven't even touched you, and look, you're dripping like a faucet, or a broken fire hydrant. And all just from servicing lil' old me. You're quite the degenerate filly fiddler, aren't you?"

Twilight winces, but nods. "I... I am."

"Yes, you are," Cozy agrees. "Now lay back and spread your legs like the whore that you are."

"Yes, Mistress," Twilight says, no longer caring about the excitement in her voice as rolls onto her back. Spreading her hindlegs, Cozy languidly moves into place, seeming to take her time just to make Twilight wait. Once plopped into position, Cozy runs a hoof along Twilight's inner thigh, causing the alicorn to shudder and squirm impatiently as the hoof stops an inch from her winking sex. Then another hoof is against her other thigh and drifting towards Twilight's teats, the nipples stiff with arousal, only to again stop and Twilight whines.

"Oh? What was that I heard? Is somepony anxious?" Cozy asks. "Why, we can't have you getting uppity and demanding. Perhaps I shouldn't do this after all."

"No!" Twilight yells, then covers her mouth with both hooves, eyes wide as Cozy stares at her with a pout.

"Oh, I see how it is. How's the old adage go? Give them an inch and they'll take a mile? I offer to reward my slave for good behavior, and she suddenly thinks she's not my pet anymore. I guess I shouldn't do this, after all."

"Please..." Twilight says hooves falling away as her voice wobbles. "I-I'm so, so sorry, Mistress. I'll be good, I promise. B-but please, I... I need this so badly."

"Oh? And what do you need, exactly?"

"I... I need you to pleasure me," she says with a gulp. "I haven't masturbated all week just like you told me. I've been waiting for my reward like a good pet until you thought I earned it. Please don't make me wait any longer."

Cozy sighs and rolls her eyes. "Golly, Twilight, you're not even trying to hide the fact that you're a desperate, degenerate filly fiddler slave anymore, are you?"

"No," Twilight says without hesitation. "I'm yours, Mistress Glow, from now on and for always... I've never been happier since you've claimed me as yours."

That actually seemed to have surprised the filly as she stares wide-eyed, but eventually she smirks and scoots forward. Without a word, and catching Twilight completely off guard, Cozy leans in and runs her tongue up Twilight's puffy labia. The alicorn's back arches instantly in response, forehooves twisting up in the sheets of the bed as her pussy releases a potent jet of marecum over the filly's muzzle just before she goes limp and is left panting.

Cozy pulls back, letting Twilight catch her breath after the miniature orgasm she just experienced, smirking as she wipes the slick, sticky fluid from her face with a giggle. "You weren't joking, huh? You really do need this." She looks at her hoof and the long strand of juice stretching down, and Twilight watches, mesmerized as Cozy sensually brings her tongue underneath the shimmering string and follows it all the way up to then lick her hoof clean.

"Honestly, I think I was starting to forget this flavor," Cozy says conversationally, smacking her lips. "I haven't had a taste since a day before my attempt to drain Equestria of its magic. Remember? When you called me to your office and had me under your desk, eating you out for 'extra friendship credit' while you graded essays? With how much extra credit you had me do back then, I must have been an A+++ student."

Twilight, head clearing, looks abashed, but nods. "Y-you were my best student. I loved reading your friendship essays. I loved how you helped with paperwork, and helped other students who struggled understanding course material-"

"But you loved my tongue between your folds most of all," Cozy cuts off with a smirk as she lowers herself once more, hooking her forehooves around the older mare's ankles. She edged closer and closer until, even though Cozy's face is half hidden from Twilight by her teats so only her smoldering red eyes are visible, the mare can feel the filly's heated breath on her sex. "All that other stuff didn't matter at all to you, did it? I could have been dumb as a sack of apples, and you'd have dragged me under your desk all the same. It must have been hard for you, all the those years in Ponyville, surrounded by tender young fillies, but too afraid to touch them. Tell me, how often did you fantasize about your friends' little sisters?"

"I-"

"And don't lie to me, Pet, or else this-" Cozy's tongue flicks out to brush Twilight, causing her to shudder minutely. "Ends here."

Twilight gulps, and answers in a whisper, "So, so many times. I imagined tasting Apple Bloom out in the orchard while her older siblings were busy with chores. Taking Sweetie behind a changing curtain while Rarity was making tea for us to chat over. One time, Scootaloo scraped her knee, and I brought her inside the library bathroom to clean and bandage it. H-her little, underaged teats were right there as I worked. I was so tempted to just... touch them..."

"But Rainbow Dash would have dropped you off of the highest cloud she could find," Cozy says, punctuating the statement with another playful lick. "Applejack would have bucked your teeth in. Rarity would have sewn your eyes shut." Twilight winces, both due to pleasure and the stinging truth of the words. "It was true with all of them. Every little filly in town had family close by that would destroy you if you touched them, so you had to content yourself with only looking and rubbing yourself raw in private. I wonder how many pointless errands you sent Spike on just to get a bit of alone time to pleasure yourself?" Cozy muses, merely speculating, yet still so right.

She really did know Twilight. She knew the alicorn better than she herself did. Cozy continues, "What must have gone through your head when you saw me, your youngest new student, so eager to please? How long did it take for you to dig up my application personally, I wonder? How excited you must have been to see I had no relatives who'd beat you up once you violated their little filly. Honestly, I'm surprised it took you a whole month before you made a move. Tell me, Slave, how eager were you when we first met?"

Twilight gulps. "I... I thought you were the most beautiful pony I'd ever seen. Before, I had only ever felt lust at most for other fillies, but I was infatuated with you from the start. You were adorable, sexy, smart... When I heard you say 'golly' for the first time, I had to excuse myself to jill off in the bathroom."

Cozy is grinning so wide that the corners of her mouth are visible behind Twilight's mound. "Disgusting," she says almost giddily, causing Twilight's heart to flutter. "Gross, depraved grown up. How did a freak like you ever become Princess of Friendship?"

It hurts, and yet, Twilight winks at the harsh words. "I don't know," she whispers in response. "It should have been you, Mistress."

"You're just saying that so I'll start licking again," Cozy accuses playfully, but Twilight shakes her head vigorously.

"No! It's true! You're so amazing! Twice the mare I am at less than half my age. If I could, I'd give you my throne, but other ponies wouldn't see what I do. Even before you tried to get rid of magic, they'd never accept a foal as their ruler. And now, they'd think you tricked me, or I was under mind control instead of seeing the truth of just how special you are."

Twilight doesn't notice the tear roll down her cheek as she thinks of the horrible things she's heard ponies say about her mistress, most behind her back, and some to her face. "Even so, sometimes I imagine what it would be like if I just came out and let the world know how much I love you. What it would be like to... to marry you, make you my wife, my princess, my mistress forever."

Twilight jerks, her reverie shattered by a rush of pleasure, the mare biting her lip as Cozy dives into her sex, licking, suckling, and slurping the resulting rush of fluid like a pony dying of her thirst. Eyes screwed shut and grip tight on Twilight's legs as she pulls herself into the older mare, it's almost as if Cozy is trying to get deeper despite being muzzle deep already.

Twilight can hardly form coherent thoughts as Cozy eats her out with a gusto for thirty seconds straight. Finally, mercifully, the filly pulls back to gasp for air, muzzle soaked and fur matted across her face. Twilight is barely given a respite from the carnal onslaught, however, as, after two big gulps of oxygen, the filly clamps her lips around the mare's swollen clitoris, grazing her teeth gently over the sensitive nub, tongue lulling over the nerve-dense tissue.

Twilight quickly approaches another orgasm, and just as she reaches the brink, Cozy bites down, not terribly hard, but enough to send a surge of pain and pleasure up her spine, catapulting her over the edge. Vision going white, Twilight is hardly aware of the filly shifting her mouth once again to encapsulate as much of the alicorn's spasming, squirting marehood as she can. Unlike when Twilight did the same for her, however, Cozy's smaller mouth has no chance to encompass it all, so her face and the sheets below are drenched as she nevertheless gulps down the product of Twilight's orgasm to the best of her ability.

Twilight is left seeing spots, extremities numb as her core from her sex to her horn buzzes and shakes with the after effects of her climax. Cozy merely smiles, face glazed and one eye shut underneath the sexual fluids that splattered over it. Twilight, chest heaving, body limp, mind fogged over, is almost disbelieving of just how world shattering that orgasm had been. Never before in her office at the School of Friendship had her mistress made her feel this amazing.

Her labored breath hitches a moment as Cozy, having begun to pull herself up over the mare, takes a moment to lick and kiss one of the hardened nipples of her teats before continuing her ascent. Once she reaches Twilight's barrel, she lays chest-to-chest with the mare as Twilight instinctively wraps her forelegs and wings around her mistress. Cozy wipes a fetlock across her eyes to open them fully and says, "Golly, Slave, you sure did make a mess of your mistress, huh? And these sheets may never be clean again."

"I'm sorry, Mistress, I'll see them burned and new ones ordered right away."

Cozy chuckles. "See that you do," she responds. "You really should be grateful for me defiling my palate with your disgusting flavor. Here, taste yourself and say you're sorry."

Cozy leans forward and captures Twilight's mouth, her tongue not even having to ask for permission as the alicorn parts her lips to grant her entry. Two slick muscles dance for several seconds, the smaller taking the lead as the larger follows obediently, and Twilight's mouth is flooded with the flavors of lavender and musk. As soon as they part, she responds, "Utterly foul. I'm so sorry you had to force yourself to bare with it for my sake, Mistress. Thank you."

Cozy merely chuckles and leans in, pushing her head underneath the mares chin. "I'm chilly," she states simply, and Twilight instantly tightens her grip and ruffles her feathers to warm her. Humming, the filly runs a hoof through the small tuft of fur on Twilight's chest, the two laying together and basking in the afterglow of their sexual escapades. Eventually, Cozy breaks the silence with, "So, marriage, huh? How do you think that'd work out with a filly?"

Twilight flinches, face blushing, but she doesn't let her embarrassment stop her from answering. "It... it probably wouldn't... until you're older, at least, and even then, there would be plenty of questions. I wouldn't care though, as long as I was yours and we were together."

Cozy doesn't respond right aware, still snuggled up under Twilight's chin, and when she does, her voice is small and so unlike her usual bravado. "When I'm older? Would you still love me then? Don't pretend a filly fiddler like you would still be interested in me once I'd outgrown your tastes."

Twilight feels a surge of desperation as she reaches down and gently, but firmly lifts the filly's chin up to meet her gaze with Cozy's. "No! That's not true at all! I... I love you, deeply and truly, Cozy Glow!" Twilight tells her, knowing she's overstepping her bounds, but overwhelmed with the need to make the filly understand. She gulps, breaking eye contact as she explains, "It's true, that your... size is part of the reason I was initially attracted to you, but it's so much more than that now. You're perfect in my eyes, and no amount of time will change how I see you."

Twilight's blush deepens, hoof falling away from the filly's chin as she goes on to admit a musing that's been on her mind for a while. "A-and besides, I asked Celestia about my own growth, since I'm an alicorn now, and she confirmed that, over the next decade or so, I'm going to continue to grow, most likely to rival, or even surpass her. That means that, even as you grow up, I'll be doing the same, so in a way, you'll still sort of be filly-sized compared to me when you're an adult... which is kind of hot to think about."

Cozy is stunned as Twilight says all of this, but then smiles gently and mimics Twilight's earlier gesture, tilting the mare's head back up with a hoof under the chin. Then she leans forward and kisses the alicorn once more, but this time with far more tenderness and love, tilting her head to the side as she lets Twilight deepen the kiss, accepting the older mare's tongue into her mouth.

Twilight runs her hooves up the filly's body, from her perky behind, her lean sides, to the bundle of muscles between her wings, before running through her blue curls to pull her closer. The two break apart, eyes lidded, cheeks flush and smiling tenderly, before Cozy smacks Twilight across the face and says, "That's for yanking my head up like that, Slave! Remember your place next time, or it's timeout in the basement and I'll get the riding crop out!"

"Sorry, Mistress!" Twilight quickly replies, even as her marehood winks at the thought of wearing the spreader bar and having rump whipped by her mistress.

"Hmph! I'm going to take a bath," Cozy declares, breaking out of Twilight's embrace to jump off of the bed and walk towards the bathroom with her nose up. "Clean up this mess and have lunch waiting for me when I'm done. A chia seed, strawberry, and banana smoothie for both of us. It's good for restoring electrolytes."

Twilight watches Cozy go with a smile, both for the care hidden behind her stern demands, and at the sight of the filly's tail drenched and stuck to one leg, an indication of just how much Cozy enjoyed 'rewarding' her slave.

She's tempted to follow her mistress into the bath to try and continue the fun, but she knows she can't disobey orders like that, no matter how much they would both enjoy it. Plus, she's feeling pretty dehydrated after all of that, and that smoothie is sounding wonderful just about now.

She might add a couple extra ingredients, though. Peach for her own, and some lavender in Cozy's. Sometimes it's better to ask for forgiveness than permission, and if she ends up in the basement as a result, well, that's a risk she's willing to take.

Author's Note

I started writing this a long time ago when I saw the image, and finally decided to finish it. Sure, it might be 90% porn with 10% plot, but hey, Cozy is Cozy, and she needs every bit of fiction she can get.

While not a foalcon writer usually, I figured I'd try my hand, and I'm proud of how this turned. I wanted to do something to set it apart from the norm, part of that being why Cozy is the one in charge, and my attempt at surprise wholesomeness at the end.
