The Twilight Sparkle Scholarship Program
Final Chapter: Bill of Sale
-by Drace Domino

“Mmm...someone’s already well-trained,” Celestia sighed as she stretched out in bed in the early morning, basking in the light of the nearby open window. Just beside her Luna was still sleeping peacefully, a mask over her face, plugs tucked into her ears, and both arms wrapped around a large, comfortable pillow. The younger of the two royal sisters naturally slept in every morning while they were on vacation, and Celestia knew better than to disturb her anytime soon. Still, she was sorely tempted to wake Luna up just for the chance to brag about what was going on underneath the covers - the warm mouth of a hot teenage whore worshipping her perfect cock.

“Anything to make you happy, Princess Celestia~” Twilight Sparkle cooed from her spot under the covers, tilting her head up just enough for the older woman to see her eyes. They were practically shining in obedience and loyalty, and when she looked to Celestia her cheek was pressed flush to the side of the other woman’s cock. Smearing herself with spit, Twilight Sparkle fawned over that member with the attention of a depraved, wanton darling - fingers running up and down it and unable to peel herself away for more than a few seconds without giving it another soft kiss. “Do you want to cum in my mouth, pussy, or ass this morning?”

“All three, Twilight,” Celestia cooed in casual fashion, as if the offer was a standard expectation. After all, if everything went as she had planned, it would be by the time all three of them returned to Equestria. She sighed contently and folded her arms underneath her head, stretching her human legs out and wiggling her toes. The strange new body given to her upon arriving in this dimension was slowly growing on her - although deep down, she was still deeply, deeply curious what it would be like to sink her proper equine cock into her whore once they returned. “Mouth first. And try not to wake Luna up, I don’t want to listen to her complain before breakfast.”

“Yes, Princess Celestia~” Twilight’s voice slipped forward once more, heavy with an adoring, dreamy tone as she went back to work. Her eyes closed and she drug her tongue across the swollen head of Celestia’s cock, swirling it back and forth and collecting the morning precum that was building upon the tip. The more that she tended to the visiting pony the more inclined Celestia was to bask in her whore’s attentions, practically melting against the mattress as she gleefully, shamelessly lost herself in the moment. All that filled the air between the trio was the gentle sound of Luna’s near-snores while she slept and the constant, wet noise of Twilight’s mouth engulfing Princess Celestia’s royal dick. “Slrp...gnnns...mmmssss…”

The first orgasm of the morning came swift, naturally enough. Celestia had woken up rock hard, thanks in part to Twilight’s attention, and it took only a few tender moments of teenage tongue to push her to the edge of her pleasure. She didn’t bother giving the girl any warning that she was about to cum - after all, Twilight would need to learn sooner or later to read her owner’s body and prepare herself for the waves of cum and the squirts of thick, dense cream. As a result, when she finally popped off in Twilight’s mouth it caught the girl by surprise, and underneath the covers Twilight could be heard to cough, gasp, and sputter all while Celestia’s cock throbbed within her grasp.

“Keep at it, Twilight,” Celestia half-soothed, half-warned her whore. Even though Twilight was choking on cum underneath the covers, she still had a job to do. “Don’t you dare stop until you’re sure I’m done cumming.”

Twilight Sparkle obeyed, just as she had been taught to do. Though that pearl-pink member underneath the covers was spasming with a torrent of cum that she wasn’t sure she could properly handle, she did her best - closing her lips around it to fill her cheeks, swallowing down what could be offered every time she had the chance, and shamelessly smearing the rest on her face. She knew that even if she couldn’t gulp down every drop, it would still please Princess Celestia if she wore it on her face by the time the blanket peeled away from her head. As she did her best with Celestia’s first orgasm of the day, Twilight Sparkle continued to pump one hand up and down at the base of the other woman’s massive member, all as the other was cradling Celestia’s sack in a delicate grasp. From time to time she even buried her mouth against the spot where the princess’ balls met her shaft, slurping in a growingly greedy desire as she was showered with spunk.

She was being paid for this job, and yet...it was still a thrill. Princess Celestia had already proven herself as being different from other clients. She was a woman that could make that teenage pussy tremble with delight, and had already forced noises of tremendous excitement from Twilight Sparkle’s throat. There was no faking it with Princess Celestia. Even now in that early morning, basked in the heat of the older woman’s cum and breathing in an almost overwhelmingly musky scent underneath the covers, Twilight Sparkle’s naked young body was raw with excitement. As such, when the blanket finally started to lift and Twilight’s cum-covered face turned upward to gaze at her client, the blush on her cheeks was genuine...as were the words that quivered from her throat.

“...I’d like for you to fuck me now, Princess Celestia,” she practically begged, with ropes of cum dangling from her trembling lower lip, and her large eyes practically shining with a desperate plea. “Please…? My little pussy wants your cock soooooo bad~”

No faking. All sincerity.

And in turn, she was met with sincerity - that of a visiting pony princess that was happy to see just how wanton and hungry her new slut was already becoming.

“Crawl onto my lap,” Celestia cooed, pinching her cock at the base and gently swinging it back and forth, inviting the girl to help herself. “Careful, now. Steer clear of Luna.”

Twilight Sparkle did just that. With a careful eye constantly set on the slumbering younger sister, she brought herself up to her knees and moved to swing one leg over Celestia’s lap. Carefully her hand pressed against the slope of Celestia’s spit-soaked rod, and she kept it perfectly balanced as she brought herself down to squeeze the folds of her pussy right against the tip. With her breathing halted in her throat and goosebumps rising on her purple flesh, the naked teenager with cum coating her face gazed down once more at Princess Celestia, waiting for that tiny nod to give her permission to act. Celestia, with a smug smile on her face and hands still gently tucked behind her head, only delivered it after making Twilight squirm for a few long, delirious moments.

As Twilight Sparkle sunk onto Princess Celestia’s cock, her eyes went large and her lips parted in a sudden gasp. The cum that had been clinging to her cheeks by that point had dripped down to her modest teenage bust, and those lovely purple breasts danced briefly as she squeezed herself down to a comfortable kneeling position. The glorious, thick inches of the older woman filled her with a ruthless presence, stretching that warm, wet entrance and probing deep within her. Once Twilight was kneeling in place, her hands slowly moved out to brace themselves against Celestia’s shoulders, and she took several long, deep breaths to steel herself for what was to come. It was such a strange experience being with the older woman - Celestia wasn’t even doing anything other than laying flat and letting Twilight ride her incredible cock, and yet the young whore was absolutely livid with joy.

“S...So...so good, Princess Celestia, you’re...you’re so…” she shuddered violently, hips convulsing as she rode that gigantic cock. When she felt the urge to moan push against the back of her throat she swiftly allowed her hands to clap around her mouth, gazing warily to where Luna was slumbering just beside them on the bed. Even if she didn’t speak any more for fear of waking her, the sentiment was clear - Princess Celestia’s dick was magnificent, and the teenage prostitute was glad to ride it. She began doing just that with slow, methodic grinds of her hips, careful not to go so fast that they displaced Luna, and always making sure to keep Celestia as deep within her as she could manage.

The older woman simply smirked as she stretched back, savoring the attention from Twilight Sparkle. Her massive cock was gripped in a snug, inviting hole that couldn’t stop squeezing and trying to milk her, and she was treated to the sight of Twilight’s beautiful body bouncing softly up and down atop her. Those plump purple tits, those tresses of sleep-tangled hair, and those glossy eyes that were already lost in the heat of the moment. While Twilight worked at giving the older woman controlled and well-measured thrusts, Celestia just smacked her lips together in self-satisfaction and spoke in a thoughtful voice.

“I think when we return to Equestria, I’m going to use my magic to keep you in this form for a bit longer,” she mused, quirking her brow as she studied the other girl. As Twilight bounced and whimpered, Celestia just chuckled in satisfaction. “I want to see how this little human body handles my pony cock...and maybe Luna’s, too, if I decide to allow it.”

“Y...Yes, Princess Celestia…” Twilight nodded, swallowing a surge of pleasure as her nethers squeezed at the other woman’s shaft. Her hips swivelled from side to side and her palms pressed flat to Celestia’s belly, keeping her balanced as she picked up the pace. “W...Whatever form you...you want me in…”

“Oh, I’m sure eventually I’ll turn you into a proper pony,” Celestia mused, smacking her lips together and chuckling idly. The breath she took in was one of absolute confidence and dominance - letting the flavor of heated air set on her tongue, her senses basking in the musky air that clung to the bed after their marathon sessions and morning affections. “But before I do...I just need to know how far I can push this adorable form of yours until it breaks.”

Twilight Sparkle eagerly nodded her head, grunting and gasping and gulping down excited breaths while she rode. It was right then and there, with the threat of Celestia keeping her as a human in Equestria purely for the purpose of packing her with pony cock, that the young woman found her own first orgasm of the morning. Her pussy clenched and convulsed, her moan broke past her lips so loud that she was certain to wake Luna, and her fingers sunk deep against Celestia’s flesh as she held on for dear life. She was quivering, spasming, almost violently shaking as she rode Celestia’s unit to a shameful peak - and she was rewarded in doing so by the climax of the older woman, as well. Once again, Celestia didn’t bother announcing her orgasm to the girl before it arrived, and by the time Twilight was at the apex of her peak that surging, hot white spunk was jetting into her with reckless vigor.

“Mmm...that’s it, take every last drop of it, you little whore…” Princess Celestia beamed, her hands finally stretching from back behind her head so she could press her palms to Twilight’s slender hips. With her grip intensifying she held the girl firmly down on her rod, making sure that it was plunged down to the deepest region she could reach as she unleashed squirt after squirt of cum once more. While she pumped Twilight full with her second burst of the morning, she utterly delighted in watching the blushing slut squirm - from the cum still clinging to Twilight’s cheeks and breasts, to the heavy blush riding her face, to the fact that the girl was inexplicably, undeniably spasming in release. She was certainly a receptive little tramp, once someone was able to fuck her to that breaking point.

“Y...Yes...thank you, P...Princess Celestia...thank you for your cum…” Twilight Sparkle suddenly collapsed forward, only able to catch herself at the last second by slipping her hands to Celestia’s shoulders. With her back arched and her hair dangling down to dust against the older woman’s cheeks, Twilight was a bit of a wreck already. Sweat clinging to her figure, nethers still quivering around a shaft that was quite content to stay inside, and her belly still warm from the load she had gulped down. Celestia wasn’t even awake for a half hour yet, and already she had managed to give Twilight a creampie in two of her holes, and no doubt had designs on the third. “...it...it feels so...so warm...so good...I can’t wait to be your pet back in Equestria…”

“Hmph. Really, sister?” The voice of stern judgement came from right beside the pair, and Celestia groaned as she looked over to the side. Sure enough, Luna was laying there with her elbow on the mattress and her cheek in her palm, the ear plugs removed and the eye mask now bridges across her forehead. Her hair was a tangled and knotted mess as it always was in the morning, and her attitude could only be described as grumpy. The usual Luna in the dawning hours of the day. “You’re really going through with it, taking this one home with us?”

“You heard her, Luna,” Celestia cooed as she stretched out a hand, fingers moving to caress fondly over Twilight’s cheek. The girl responded by grinding back into the older woman’s touch, nuzzling her with a purr escaping the back of her throat. “She wants nothing more than to sit at the base of the throne worshipping my dick. Isn’t that right, Twilight?”

“Mmm, yes, Princess~” the fawning response followed, and Twilight Sparkle bumped her hips forward to grind against Celestia’s cock anew. She was splitting her attention now, however, with a hand moving out to slip under the covers, creeping towards Luna’s body. The navy-skinned woman’s eyes lifted considerably as soon as a pair of warm teenage fingers found their way around her morning erection, squeezing softly just as Twilight whispered in an alluring, doting tone. “Princess Luna…? Can I please help you this morning, too? All I want is to make the royal sisters happy…”

Celestia just watched with a smug smile as her sister squirmed underneath the attention. For all of her attitude, for all of the chiding that she offered her big sister, there was no way she could deny the offer of getting off with their shared slut this early. Luna didn’t speak up as she rolled herself up to her knees, but the sight of her large, dark-skinned member was evidence that she would accept the invitation. Her eyes darted from Twilight’s hips where she was still mounted on her older sister all the way up to those pretty lips, smiling at her with a tongue lashing out to coax her up to her mouth. Luna very nearly stood up on the bed to feed Twilight her dick just then and there, but before she could Celestia spoke up with a lazy chuckle, and her hands glided down to caress Twilight’s backside while she did so.

“Luna? I think it’s time we show our little whore what it’s like to be truly stuffed with royalty,” she pulled Twilight forward with that, careful so that her cock remained firmly planted inside that trembling purple pussy. As she lurched the younger woman against her she held Twilight to a point where her cockhead and an extra two inches were still stuffed inside her cum-filled cunt, and yet still angling her so that some of the pink of her fuckable hole was still visible. Celestia purred as she tossed a glance at her sister - in particular, that throbbing, dark length that desperately needed a place to go. “Join me inside of her pussy, won’t you?”

It was hard to tell which between the two of them looked more shocked at the offer, but considering that Twilight’s surprise soon melted into excitement it seemed like any hesitation was quickly pushed aside. The young woman even giggled as she braced her hands on Celestia’s shoulders, looking over to Luna with a heady gaze and a sensual, teasing nibble on her bottom lip.

“That’s a wonderful idea, Princess Luna…” she groaned, and took a deep, bracing breath to prepare herself. Even one of the two sisters sported a cock too big for most girls, but both of them at the same time? As obscene and depraved as it sounded, there was a part of the teenage hooker that was thrilling at the prospect. It seemed like that was par for course when it came to Princess Celestia - that magnificent visiting pony was able to force Twilight into passion she had never felt with any client ever before. “Please? Please share me with your sister? She already filled me up, but my little cunt can still hold you both! I’ll do my best to show you what a good cocksleeve I’ll be in Equestria!”

Luna, even with her irritations at her sister and her gentle concern for the younger woman, couldn’t resist any longer. With her typical irate grunt she moved to oblige, bringing herself to kneel just behind Twilight Sparkle, her legs tenting around her sister’s own as she did so. The soft slap of her dark-skinned length falling to Twilight’s backside hit the air, and as she pushed herself slowly into position Twilight tilted her head downward, staring into the eyes of the older woman that seemed so firmly intent on breaking her. Celestia merely lifted a hand and pressed a finger to Twilight’s cheek - collecting some of that leftover cum and ushering it to the girl’s lips. As Twilight suckled on Celestia’s digit, swirling her tongue around and swallowing down that note of flavor, the visiting ruler of Equestria offered a hungry whisper, her voice heavy with desire, domination, and pride.

“When it’s time to leave, you’ll be so eager to get my pony cock inside of you that you won’t even want to say goodbye to your friends and family,” she hissed, low enough that Luna couldn’t quite hear while she focused on positioning herself. Celestia drew in close, whispering to the girl’s ear as Twilight suckled her finger. “You belong to me, Twilight Sparkle. And I’m the only one you love now.”

“Y...Yessssss…” Agreement rumbled from the depths of Twilight’s throat as Luna started to push herself forward, unwittingly playing a part in this moment of shattering Twilight’s defenses. That big, blue unit was pushing into an already overstuffed pussy, and as she did so her length was left grinding against her sister’s own, swimming in the creampie that Celestia already filled Twilight with. To think that this was only the morning of the first of their last two days together was enough to make Twilight lose herself completely - she was already being double-stuffed and swearing her complete devotion, already little more than a mindless cocksleeve to be shared between two glorious women and their equally glorious cocks. As Luna squeezed inside, as Twilight’s tiny teenage fuckhole struggled to hold them both within, the young woman’s entire body bucked and convulsed, and she gazed down at Princess Celestia with the glazed look of an adoring sex slave in her eyes. Loyal. Obedient. Enamoured with her new owner. “I...I belong...to you...Princess…”

Luna was too focused on forcing her cock into that impossibly tight entrance to chide her big sister, and as such she merely held her hands against Twilight Sparkle’s backside while edging deeper and deeper. As she pushed, she ended up carrying Celestia’s cock right alongside her, and by the time she managed to hilt herself within the girl’s tender entrance she could still feel Celestia’s tip tribbing against her own. Within the depths of the young whore they could feel each other’s pulse through the steady throbbing of their cocks, squeezed fiercely tight together by Twilight’s walls wringing against them with every passing second. The girl was soft, warm, wet, and inviting - and the creampie that Celestia had already deposited ensured that they’d have all the lubrication they needed to make sure that Twilight enjoyed her double penetration. Once Luna collected herself and came to terms with the pleasure of being so tightly gripped alongside her sister, the woman lifted her head and gazed down - past the back of Twilight’s head to where Celestia lay with a smug smile plastered on her face.

“Sister…” Luna finally found the strength to offer her a voice if slight disapproval, but said nothing more as the pleasure of the moment started to overwhelm her. Thanks to the unusual position, the priority for movement was entirely on Luna herself - little Twilight could hardly move considering how packed she was, and if Celestia dared to thrust she ran the risk of forcing both of their cocks free of that purple cunt. It was entirely up to that dark-skinned member to grind back and forth, pull out to near the point of slipping free, only to plunge right back in again and fuck Twilight down to her core. Luna braced her hands to Twilight’s rump as she started to do just that, her head swimming in the early morning haze and just how quickly she was yanked into this new brand of lewd madness.

While she was doubly fucked, Twilight Sparkle simply did her best to keep her wits about her...with mixed results. She was stretched further than she ever remembered being before, fucked deeper than her teenaged figure could recall, packed with more cock than she would’ve been in a whole night’s worth of work with any other clients. Her fingers were white-knuckled as she gripped Celestia’s shoulders, and with her eyes closed and lips parted to unleash a torrent of squeaks and gasps, Twilight was raw and exposed - vulnerable like never before to the words of the dominant visiting pony that was taking such delight in sharing her with her sister. Each word spoken by Celestia in that moment hit Twilight Sparkle particularly hard, keeping her constantly at the edge of yet another spasming orgasm, no matter how much she wished to resist the impulse.

“You’re so tight...so sensitive...so slutty…” Celestia cooed, her overbearing dominance slightly dulled by the sweetness in her voice. She gave Twilight Sparkle moments of gentle affection while shamelessly splitting her alongside another dick, making sure that the discomfort of being so utterly packed was given a sharp counter in the form of tenderness. Hands massaged Twilight’s modest bust, rubbing the excess cum against her nipples. Lips drifted up and down Twilight’s face for a few soft and delicate kisses, even including the slow drag of the older woman’s teeth across her bare, purple shoulder. Her breath, sweet and sincere, was cascading over Twilight’s sensitive figure even while her cock trembled in glee - words kind enough that it was almost strange to realize that the same source of such affection was the same one that brought Twilight to this tenuously-stretched state. “You’re the perfect pet, Twilight Sparkle. The perfect lover. The perfect...student.”

Twilight Sparkle groaned and convulsed upon hearing it, her head bucking to the point that her forehead nuzzled Celestia’s throat and her nethers squeezed harder on those two throbbing dicks within her. As Luna continued to plunge her, as the cum within her overfilled pussy churned and coated both lengths, Twilight was left breathing heavy and desperately, clinging to the older woman as waves of shame, pleasure, and pride swept over her. She was very near the apex of yet another thrashing orgasm, and it was hard to tell which was pushing her there quicker - the members claiming her in tandem, the gentle notes of affection from Princess Celestia, or the mere knowledge that she was, in no uncertain terms, the perfect student.

In so many ways, that was everything Twilight Sparkle ever wanted, and she had it there trapped between two visiting Equestrian princesses. Packed with cum and left sweaty and exhausted between them, Twilight Sparkle slumped forward onto the pearl-pink body of Princess Celestia, nearly melting into her embrace.

“Two more days, dear…” Princess Celestia cooed at the corner of Twilight’s ear, just as her cock started to twitch yet again. “...two more days, and the only clothing you’ll ever wear again is a leash and collar.”

***

It was undeniable that Celestia was eager to get Twilight Sparkle back to Equestria to get her suited into her new life, and the only reason she didn’t push for that was the insistence of her little sister. Luna was clearly the voice of reason between the two women, and because that voice was so particularly sharp and unshy about putting Celestia in her place, there was no way the older of the two ponies could ignore it. There was still plenty for Luna to see in the human world and she’d be damned if she missed out on it - from the restaurants with strange cuisine that wasn’t hay-based to the horse and buggy ride around town which both of the princesses felt...oddly conflicted about. The early afternoon was filled with self-appointed Luna time, with Celestia dragging her heels behind her and Twilight Sparkle close at hand.

There was a shift in their group dynamic, though - specifically, how it involved the young whore that was in their service. When her time with Luna and Celestia had first begun, Twilight Sparkle was deeply engaged in what Luna wanted to do. She shared the experiences with her, often getting deep into the history of her town and thrilling in learning new things. The two of them were insufferable at a museum just a few days ago, and now? Now, Twilight Sparkle barely blinked, and didn’t say anything unless it was words of fawning adoration to the older of the two sisters. Twilight Sparkle remained close at Celestia’s side as the princess held an arm around her, nodding gently when Celestia whispered against her ear and barely even acknowledging anyone else. It would’ve been awkward were it not for Luna’s ability to self-motivate and feel engaged in her tourism, though even in the midst of her delight she still every now and again glanced at her big sister and the slut, nibbling her lower lip in concern.

“Sister, not here!” Luna hissed while the two were at a fine restaurant, nestled in one of the back rooms. She was holding her silverware with a white-knuckled grasp, eyes narrow as she looked at Celestia. “We are in public! You don’t want to get in trouble with the authorities of this dimension, do you?!”

“Relax, Luna, you always worry so much,” Celestia cooed, stretching back with her arms over the edge of the booth and her posture lazy and relaxed. From just above the edge of the table, the back of Twilight Sparkle’s head could be seen dipping up and down, along with a steady slurping noise that filled the air. “Besides, you heard her. I asked what she wanted for lunch, and -- what was it you said again, Twilight?”

Twilight Sparkle lifted her head from Celestia’s cock, face slathered with spit and wearing a bright, wide smile on her face. With glazed eyes and foggy glasses she looked from Luna to Celestia, and spoke up in a voice nearly loud enough to alert the couple dining a few tables over.

“I just want your cum, Princess Celestia!”

It went on like that throughout the entire day. When Celestia wasn’t feeding Twilight Sparkle her cock at a restaurant or during a movie, she was fingering the young woman while they rode the horse and buggy, even going so far as to make Twilight flash her purple teenage pussy to passing people on the road. While Twilight Sparkle had gone off the deep end of worshipping the older woman, Celestia, too was falling deep into her most profane impulses. She was reckless. Ravenous. Constantly bulging the front of her pants and almost always either waiting to recharge or mere seconds from yanking her dick out once more. When the girls went to a small fashion show at CHS performed for their benefit by Rarity, they were barely three dresses in before Celestia stood up with Twilight in hand, giving herself a small nod as she excused herself.

“I need to...use the restroom,” she whispered to her little sister, who simply rolled her eyes. Moments later she was gone with the hooker in tow, leaving Princess Luna sitting there in the audience while Rarity’s next model switched outfits. Casually, she leaned back against the chairs and tilted her head to the woman beside her - none other than Vice-Principal Luna, who was regarding her with a sympathetic look.

“So…” Princess Luna whispered, curiously. “...is your Celestia a horny idiot, too?”

Horny idiot or no, Celestia was having fun. She didn’t even make it to her intended destination of the restroom, stopping in the hallway just outside the auditorium and pushing Twilight Sparkle suddenly against the lockers. The girl was dressed to be fucked in a shortened version of her pleated schoolgirl skirt and an absolute lack of panties, and when Celestia wedged her against the wall she gave a tiny gasp as the older woman’s hands slithered underneath her to grasp fiercely at her ass. Riding against Celestia’s lap, Twilight lifted her feet off the ground and relied on the pressure of the visiting princess to keep her up, whimpering as the older woman bared down against her.

“P...Princess...Ce...Celestia…” she whined, wriggled, and hooked her heels behind Celestia’s backside. Her arms were looping over her shoulders and she could feel Celestia grind harder against her, split seconds before she dipped down to start unleashing her cock. “F...fuck me, please...please...my little pussy wants your cuuuuum~”

“You’ll get all you want, whore,” Celestia whispered in return, chuckling as she finally squeezed her tip against that quivering purple entrance. While she worked herself inside Twilight Sparkle’s face scrunched up in discomfort melting swiftly into delight - the older woman’s girth was downright enormous as she prepared to fuck her on the other side of a packed auditorium. Twilight’s head was hazy and her pussy was stretched as Celestia started to rock forward, fucking her right up against the lockers and ushering her breath in a wet heat to the girl’s throat. “Maybe when I’m done I’ll make you go out on the catwalk...show all your little classmates the creampie leaking down your thighs. It’s not like you’ll ever see them again once you leave with me, cunt!”

“Y...yes...anything...anything for...you…”

Princess Celestia squeezed inside of Twilight Sparkle yet again, pushing herself down to the hilt. As she did so, her breasts wedged fiercely to Twilight’s chest and kept her fiercely pinned, enough so that Celestia could merely buck her hips back and forth while keeping Twilight balanced between herself and the wall. With that positioned locked the visiting pony rushed herself back and forth with the same reckless zeal that she had already relished in during her time with Twilight, pounding her hard, wet, and fast and stretching that tender pussy as much as she had ever managed. Though her girth was enormous by human standards it still paled in comparison to what she’d be like as a pony, ensuring that when the time came and Twilight was left trapped in her human form in Equestria, she’d need to endure something much, much bigger. And while she fucked the teenage whore just a wall away from all of her friends, Celestia buried her mouth against Twilight’s ear, reminding her of just where she stood between them.

“Tight little thing, aren’t you?” she murmured, grinning. “I can feel your pussy trying to milk my cock. Desperate for it. I can’t believe that you ever charged for sex, considering what a depraved slut you are. Or maybe...maybe you just needed someone that finally knew how to fuck you properly.”

Twilight Sparkle didn’t respond, simply because she was too busy cumming. Again. Something about this version of Celestia made her fire on all cylinders, her body spasming and her pussy quivering while it was banged so rough and wet. She clutched at Celestia and worshipped the other woman’s throat with her lips and tongue, suckling against her in pathetic, helpless, wanton glee while she was reamed. Her nethers were aching with desire as they squeezed Celestia in a hopeful bid to milk her of even more delicious cum, and she cared nothing for the people that passed her vision in the distant hallway. Ditzy Doo, Maud Pie, even Principal Celestia herself...so many people casually walked by only to see her getting fucked. The shame of it all just made her groan all the harder.

When Princess Celestia finally came, she made good on her promise to give it to Twilight as deep as she could muster. While the girl’s purple legs were still hitched around her waist, celestia unloaded her massive creampie into Twilight’s pussy, packing it nice and deep while the girl squirmed and whimpered. She’d be dripping it all the way back to her seat at the fashion show considering she didn’t have any panties, and though she didn’t realize it yet, Celestia was planning on having her flash that cum-filled pussy to every model on the catwalk - especially Rarity herself. As she pressed against Twilight with cum oozing from the girl’s pussy, the teenage prostitute simply melted to Celestia’s form, whispering to her throat as her thighs were still left spasming.

“I...I belong...to you, Princess…”

“I know you do, whore,” Celestia whispered, stirring Twilight’s pussy with a slow swing of her hips. “Let’s go watch the rest of the show, while I think of what to do to you next.”

***

From the fashion show straight to the hotel, Twilight Sparkle was still carrying Celestia’s creampie by the time the older woman got her fingers inside of her again. It was during the cab ride back, with Luna awkwardly sitting behind the driver while her big sister shamelessly pawed at and teased the young woman beside her. On more than one occasion Luna exchanged glances with the driver in the rear view mirror, and when they were finally dropped off she made sure to tip him extra - as well as grumbling under her breath that she was sorry for the squirting orgasm the girl had in the backseat.

“...my sister is a horny idiot,” the younger princess murmured, as she slipped an actual, genuine ruby into the cabbie’s hand. “This should cover getting the seat cleaned.” By the time she looked up from paying the tab, Celestia was already carrying Twilight Sparkle in her arms to the hotel door, and Luna just gave a sigh as she rolled her eyes. It was going to be a long night.

A long night, at least, that Luna was able to engage in. She had behaved herself all day long, at least after she and Celestia double-stuffed Twilight Sparkle in the morning. Once the hotel room door was closed once more and the mayhem began again, Luna was finally allowed to let her hair down to experience some of the more carnal benefits of their arrangement. With a collected expression and calm demeanor she locked the door behind them, only to turn around and see that Twilight Sparkle was already laying flat against the bed, her head dangling over the edge while Celestia was facefucking her.

“Luna, what are you waiting for?” Celestia grinned, waving her little sister over. She pointed to Twilight’s lap, where the girl was laying with knees bent and thighs spread, a hand underneath her skirt so she could paw at her purple pussy. “Twilight’s been wanting to fuck you all day, and you’ve been a real stick in the mud!”

“Sister, I did not come to this dimension purely to have sex with Twilight!” Luna persisted, even though her hands were already at her belt. She was stripping down while making her way to the bed, crawling forward and allowing that big, blue cock to suddenly flop forward onto Twilight’s lap. Despite her protests, it was clear the long day of watching Twilight and Celestia go at it took its toll on her - she was engorged, thick, and drooling precum. She simply had the self-control to keep herself in check until that moment. Even now, as she slipped her cocktip forward against Twilight’s overflowing pussy, Luna pointed a finger straight at her big sister’s nose while she admonished her. “We only have one day left in this dimension, and I don’t want to waste all of it apologizing to people for the stains the two of you left in their businesses!”

“Oh, don’t worry, Luna,” Celestia chirped, hilt-deep in Twilight’s mouth and making the girl’s purple throat bulge. Twilight was gagging and groaning and drooling, but neither of the sisters paid her any head once they began to spitroast her. “We’re not leaving the hotel room at all tomorrow.”

“...that is not what I meant, Sister, I--” Luna paused, just as she felt Twilight’s pussy squeezing her cock, encouraging her to thrust deeper. The young woman’s legs even stretched out to hook her heels behind Luna’s backside, pulling her forward much as she did to her big sister just a little bit ago. With a heavy blush crossing her face, Luna finally gave a tiny grunt, leaning forward to start pumping into Twilight. “Well. Perhaps it would be nice to...take it easy before we return to Equestria.”

As the two visiting ponies began to thrust inside of Twilight Sparkle, the young woman shivered in absolute glee. She was their obedient and loyal cocksleeve at that point, happy to be used again and again and again. And though neither woman asked what she thought of the matter, she was thrilled to be their slut for the next full day. Pumped with cum, stretched with cock, and shown off for the yowling, depraved slut she never knew she could be.

Twilight Sparkle was learning a lot about herself that week. Specifically, how quickly she could lose herself in the fun of being a whore...so long as the sex was good enough.

***

The next day felt like ages, and within that twenty-four hour span of time Celestia and Luna gave her more orgasms than she had in her entire life up to that point combined. She woke up stretched around Celestia’s cock, the first flavor of the morning to greet her lips the taste of Luna’s precum. Left weary and sore from the long day before, Twilight Sparkle was nonetheless the prey of the two visiting princess from the very second she was forced awake, and no matter how weary and exhausted she was, no matter how much her head was spinning or her muscles ached, she was delighted to be their whore.

The hotel bedroom didn’t quite have the same public thrill of getting fucked at restaurants and fashion shows, but what it lacked in exhibition it more than made up for in allowing the two sisters to truly unleash themselves upon her. Celestia was controlling the narrative from the very beginning, constantly keeping her throbbing dick pressed against or inside of Twilight’s slender teenage body, ensuring that every waking moment the girl had she was reminded of just what joys it could force upon her. And besides...there was still plenty of time to show Twilight’s sluttiness off to strangers, like when Celestia called for room service to deliver their breakfast while she and Luna were fucking Twilight in her pussy and ass, respectively. Twilight would have been embarrassed when the delivery girl held out a receipt for Celestia to sign, but she couldn’t think past the thrashing, intense orgasms that were rocking through her.

“W...Wow, ma’am, thank you very much!” the delivery girl gasped as she looked at the receipt, mere inches away from where a young hooker was getting pounded in both her holes. “That’s a very generous tip!” Celestia just smirked from her spot laying flat on the bed, her hands drifting down to Twilight’s hips and holding the girl in place as she bucked forward from below.

“I’m in a pretty good mood, as you can probably tell,” she smirked, and gestured towards the door for the delivery girl. “That’s all we need, thank you.”

She wouldn’t be the last hotel employee to see Twilight Sparkle in a compromising position. Hell, she wouldn’t even be the last to see her like that before lunch. With neither of the three women leaving anytime soon, they had to rely on the staff to bring them meals...and not for a single one of them did the trio stop their antics. Even Luna, usually so reserved and demure about such matters, found herself losing her senses in the heat of pleasure to the point that when the lunch delivery came she was sitting naked side by side with her sister while Twilight Sparkle was crouching in front of them, sucking their cocks in alternating bits of attention.

The day was shameless. Tireless. A celebration of all of the lusty training that Celestia had put Twilight Sparkle under - and a full culmination of her hard, dutiful work. She was training the young woman for something very special, outfitting her for a future of working up and down her equine cock back home, and Twilight was already proving herself to be every bit the overachiever that her pony self was. The only difference was that while Princess Twilight excelled at magic and study, this one was untouchable when it came to using her body to squeeze every last drop of cum out of the royal sisters, all while remaining utterly insatiable.

From morning to afternoon, from afternoon to evening, and from evening to night - Twilight Sparkle could barely remember a handful of minutes throughout the day when she wasn’t being violated by one of the two. Luna was more tender while fucking the student slut, rutting her from above while Celestia took her morning shower or gently coaxing the girl to rim her ass as her big sister ate lunch. Celestia, on the other hand, was as demanding as she’d ever been. Countless toys were wedged into Twilight Sparkle that day, from plugs to vibrators to a horse tail that she was made to swish around from side to side as she pranced naked for her new owners. When the dinner delivery came, Twilight Sparkle was the one to answer the door while stuffed with toys - her naked body wearing nothing more than buzzing clips on her nipples, a string of beads inside of her ass, and an eggshell vibrator taped against the hood of her pussy. She opened the door with cum on her blushing face and drool that smeared over her cheeks and across her goggles, addressing the delivery girl with a smile.

“Hello,” she offered fondly, gesturing to the center of the room. “You can put the food there. Don’t mind the smell - my princesses have been fucking my worthless whore body all day.”

It was the way the entire night went, and it culminated with Celestia and Twilight Sparkle all alone in the dead of night. Luna finally passed out from the long day of passion, dozing peacefully at the edge of the bed with her cock limp and a line of spit dangling from the corner of her lips, falling to the mattress below. Beside her, Twilight Sparkle was flat on her back as Celestia claimed her from above, steadily pumping in and out of the young woman with their faces near and their breathing shared. The older woman was practically beaming as she jammed her cock deep into Twilight’s ass - each time making her struggle and spasm, and squeeze a little of her overflowing creampie out of a trembling pussy.

“Y...yes...please...please more...more, you’re...you’re so good…” Twilight Sparkle’s head was cloudy, and there wasn’t a single lie in her voice. Over the past week, if there was one thing she had learned it was that Princess Celestia was, beyond a shadow of a doubt, the best lover she ever had. That day alone she had cum so much that she needed to slip into the shower to collect her thoughts, scrubbing herself down and even gently crying tears of overwhelmed delight. The things that Princess Celestia made Twilight Sparkle’s body do were...unbelievable! More than any client. More than Sugarcoat. More than any of her greatest fantasies. Even now, with her tender, well-used ass sore, she was gleefully happy to hang on Celestia’s shoulders and gaze fondly up into her eyes. “...I’m...I’m so happy to be your slut…”

Princess Celestia didn’t respond beyond lunging forward one last time and giving Twilight the cum she craved, depositing that last load deep, deep within Twilight’s ass. The girl whined and whimpered, her entire body trembled in yet another fit of climax, and by the time her legs slumped off of Celestia’s hips she was already starting to drift to sleep. That exhausted, purple body of the teenage whore had finally been given enough cum to keep her satiated, and by the time she fell asleep Celestia was still inside of her ass and her lithe frame was left sweaty and pumped full of warm, creamy delight.

Gently, Princess Celestia walked her fingers across Twilight Sparkle’s belly, chuckling as she offered a tiny whisper.

“I...am going to enjoy keeping you on a leash, Twilight,” she cooed, moments before drifting off to bed herself, with dreams of a long future ahead of them wherein Twilight Sparkle remained firmly within her clutches. She’d always wanted a Twilight Sparkle of her very own, after all.

The next morning, Twilight Sparkle stepped out of the shower, fully dressed in her school uniform once more. Her hair was neatly tied into a bun at the back of her head, her clothes were fresh and clean thanks to the hotel’s laundry service, and she had brushed her teeth free of the taste of Princess Celestia’s cum (since the older woman demanded that morning blowjob.) As she stepped out into the main portion of their hotel room with her glasses perched perfectly on her nose, she turned towards Celestia and Luna with a small nod of her head, greeting the pair politely.

“Princess Celestia. Princess Luna.” Twilight Sparkle regarded both visiting ponies - each one of them already dressed and with a small bag of luggage close at hand. “Did you enjoy your visit to my dimension?”

“It was wonderful, Twilight!” Princess Luna beamed, and Twilight could immediately tell that her voice was genuine - and not merely born from the fun they had having sex. “There’s still so much I want to see! Perhaps when we return for a visit, we can further explore some of the sights we didn’t have time to witness.”

“Maybe we’ll return.” Princess Celestia chirped up with a grin, looking as smug and dominant as ever. After all, she was about to head back to Equestria with her whore in tow - primed to turn Twilight Sparkle into a wanton, depraved cocksleeve. “But I don’t know why we’d need to, considering we’re taking the best thing here with us.”

Twilight Sparkle paused, tilted her head towards Princess Celestia, and calmly adjusted her glasses.

“I’m sorry, Princess Celestia, but I have zero intention of going with you,” her words were objectively blunt, without a trace of hesitation or a single pause in her statement. She casually walked over to the edge of the bed where her bookbag was sitting, continuing to speak as she fished around in it for her tablet. “I was simply putting on a performance for the benefit of your enjoyment. It seemed like the fantasy of taking me back to Equestria with you was deeply connected to your satisfaction, and so I leaned into that roleplay. Let’s settle up the tab now, yes?”

The reactions between the two sisters were mixed. At first, both of them were looking at Twilight Sparkle with wide and surprised eyes, their faces showcasing disbelief at the girl’s blunt statements. As early as that very morning, Twilight was still fawning over Celestia’s cock and speaking of how desperately she wanted to return with them to be their pet, and now...now, she was tapping away on her tablet, sorting out what she was owed. As the shock wore off, Celestia’s look of disbelief turned into one of eye-twitching disappointment, the color draining from her face and a tiny squeak escaping from the back of her throat.

Luna, on the other hand, could only hold back a smirk for a few precious seconds before breaking out into heavy, desperate laughter.

“Haaaaaaa ha haaaaaaa! This is glorious fun!” Luna slapped her knee, pointing at Twilight, and then Celestia, and then back again. “Sister, you really thought...and she was pretending...and you...oh, how marvelous! I’ll be laughing about this for days, dear sister!”

While Luna continued to have herself a hearty laugh, Twilight Sparkle finally sauntered close to Celestia, who was still standing there with one eye twitching and her mouth agape. Ignoring the older woman’s stunned status, Twilight held the tablet out within Celestia’s eyeline, pointing out the bits and pieces of what was an increasingly large bill.

“So, as per the terms of our agreement, I added surcharges for various services that I rendered during your stay,” everything was itemized, and she had their sexual exploits chronicled over the past week down to the orgasm. “You’ll see the public sex charges are on a sliding scale depending on the risk associated with being caught, and the various people that witnessed us engaging in our transaction. Then of course there’s the charges for fucking me with oversized toys, the extra fees associated with double penetration, spitroasting, and the double-stuffing you gave me yesterday morning. Let’s see...there’s the cost to cover my massage session I’m going to need today to work out how sore you left me, the cost of the panties you threw out the window of the cab, and this part at the very end is the extra cost for this morning’s blowjob.”

She paused, adjusted her glasses, and offered Celestia an almost consoling smile.

“I didn’t charge you extra for making me swallow your cum on that one,” she patted Celestia’s shoulder, kindly. “Consider that on the house.”

While Luna continued to howl with laughter, Celestia’s eyes darted across the tablet with the long, itemized bill laid out before her. When she finally had a chance to take it all in and see just how much she owed for all this madness, she had just one question that squeaked from the back of her throat.

“Did...did you really have those orgasms?”

In response, Twilight Sparkle remained nebulous, quirking her brow as she folded her hands behind her back.

“Any pleasure I did or did not have is completely irrelevant, Princess Celestia,” she responded sharply and simply. “This is purely business.”

***

It was a long, long weekend of rest and relaxation for Twilight Sparkle after sending the princesses back home. A good weekend to be sure - mostly spent getting tended to with massages and lovely food, all while counting her boundless riches upon the conclusion of the biggest job she’d ever complete. After spending a full week as the personal sex slave of a pair of actual pony princesses, she deserved the chance to treat herself, after all!

It was Monday evening after school that she was walking alongside her girlfriend, both of them staying true to form. They weren’t holding hands as so many girls might have been, but were instead both looking at their phone or their tablet, pouring over information of their newfound wealth and making future plans. Business was booming for the pair like never before, and even if they’d never see a payday as big as the royal sisters...there was still plenty for them to work with.

“Sugarcoat?” Twilight Sparkle spoke, fingers moving across her tablet. The two were walking a familiar path towards a familiar building - the same building where this all started so long ago. “I’m starting to think it’s time to change the end goal of our business plan. I...don’t think it’s prudent for us to go to college anymore.”

“Me neither,” Sugarcoat was quick to respond. “Even before your time with the princesses, we were already making much more than is generally predicted even for an eight year doctorate. Provided our looks continue to maintain until our mid-twenties, I see no reason why we couldn’t retire by twenty-six to pursue private passions.”

“Agreed,” Twilight nodded, lifting her head to regard her girlfriend. “Although...it wouldn’t hurt to make contingency plans, just in case we’d like to retire even earlier. We don’t need to go to college to be financially successful, but...it might still be fun. And I certainly don’t want to stop learning anytime soon.”

“We can sort out our long term plans soon, Twilight,” Sugarcoat smiled, shut off her phone, and held out a hand for her girlfriend. At long last Twilight finally slipped her palm into that of the other’s, just as they neared the front door of a certain sex shop - where a certain glory hole was where their relationship first began. “But I think we’re going to be just fine. We clearly don’t have any limit on how much money we can earn with our bodies.”

Twilight Sparkle’s hand tightened within the grasp of Sugarcoat’s, and the two slipped inside the sex shop, turning their attention to where the owner was still lounging against the wall. Tempest Shadow grunted at the pair with a slightly raised brow, her arms folded across her chest and a mild scowl tugging at her lips.

“What do you two sluts want?” she grumbled. “Haven’t seen you in months. Bitches forgot all about me once you went big time.”

“Sorry, Tempest, you simply couldn’t afford us,” Twilight explained simply, before lifting her joined hand with Sugarcoat. “Would you mind if we visited our old hole today, though? We thought it would be a nice way to...relax. Unwind.”

Granted, sucking cock for twenty dollars and getting fucked for forty was a massive, massive pay cut by the day’s standards...but what could Twilight say? She was feeling romantic. And rich. Incredibly, incredibly rich.

“Hmph. Fine, knock yourselves out,” Tempest grunted, before looking the pair up and down. Judging from the fact she already had a hand in her pocket to fish out some money, it was clear that she’d be one of their first customers once they were settled. “The new cocksucker’s already in there, though, so you’ll have to kick ‘em out.”

At that, Sugarcoat and Twilight Sparkle exchanged casual glances, but went ahead regardless. As they walked, Twilight took a deep breath as she took in the familiar sights and sounds of their old whorish stomping ground - the place where her plan to pay for college with her mouth and pussy first manifested. There was an idea already brewing within her that she and Sugarcoat could discuss later, but...surely, Tempest Shadow wouldn’t mind selling the sex shop, if a nice enough offer was made.

“Sugarcoat?” Twilight Sparkle spoke casually, standing by the old door leading to the cocksucking booth. Judging from the sign on the door, both sides were currently in use - someone was cashing in a blowjob from the new mouth for hire. Pausing at the door, Twilight squeezed her girlfriend’s hands, and leaned forward to give her a gentle kiss on the corner of her lips. “Thank you for engaging in this rewarding business with me. There is no one I would rather be partners with.”

“...I love you too,” Sugarcoat grumbled in shy response, and nudged Twilight towards the door. “C’mon. Whoever’s in there, we can definitely do a better job than her.”

With a giggle, the pair invited themselves into the same room they first did business, only to find that it wasn’t a “her” behind the door at all.

As a big, red cock was sticking through the hole, Flash Sentry’s head turned back to look at the opening door. Threads of cum were connecting his shocked lips to the tip of that glistening crimson unit, and he offered a squeal of surprise upon being caught.

“Twilight!”

Twilight Sparkle and Sugarcoat just stood side-by-side and hand-in-hand, each regarding Flash Sentry finish up his work with the same look of bemused interest. Twilight’s eyes in particular flashed with opportunistic delight, and she licked her lips in pointed fashion before speaking.

“Flash?” She gazed at the cocksucking young man, gesturing to the cum on his face and the pile of twenties scattered around his knees. “Would you like to work for us?”
