Celestia's Endurance Test
Mount Everhoof stood as a magnificent beacon in the Equestrian landscape, towering far higher into the untamed skies than any other natural monument in existence. If any unlucky souls were diligent enough to ever reach the mountain’s snowy peaks, the ground below couldn’t even be seen past the thick cloudlines that circled the mountainscape. However, due to the extreme elevations that the peak reached, along with the blistering winds at below-freezing temperatures, there were only a few select species that could survive lasting on top of Mount Everhoof longer than an hour at most. In fact, unless evolution or genetic mutation were involved, the only feasible means for one to stand at the snowy mountaintops would be with the aid of expert-level magic, as well as an Alicorn’s near-immortal biology.
With all that information in mind, Twilight Sparkle needed a moment as she stood at the very top of the mountain with a tightly-pursed muzzle. She was wearing a heavy faux-fur coat with matching boots (courtesy of Rarity from her Canterlot Boutique), but it did nothing to counteract the stinging winds that pierced down to her fur. Her legs were shivering like mad, and every weak breath expelled a heavy plume of steam that nearly froze before hitting the ground. With the way her teeth were chattering incessantly, it was hard to believe she would last much longer out in these unforgiving conditions.
Of course, it was even harder to believe that the Alicorn beside her was showing no strong discomfort whatsoever.
Unlike Twilight, who was shaking more than a prisoner on death row, Princess Celestia was standing rather casually in her own plush coat. Even though her slender legs were completely bare, with the hooves buried in the powdery snow beneath them, they weren’t shivering in the slightest despite the extreme temperatures. Twilight couldn’t help looking up at her, her muzzle notably skewed in a mixture of disbelief and slight envy. While she may have known about her mentor’s near Goddess-like abilities, including her heightened tolerance to most extreme climates, it was still jarring to witness her abilities being displayed before her very eyes.
“Aaaahhhhh…” Celestia took a deep breath (another feat that Twilight found to be near-impossible to do herself), and sighed as she stared out from the peak with a contented smile. Even though the skies were pitch-black, the illumination from Luna’s moon helped to light up the seemingly endless sea of clouds that spread out far below them. If Twilight hadn’t known where they were, she would’ve likely assumed the two ended up in the afterlife or something. But even with her hooves feeling like they were about to go numb, she couldn’t deny why her mentor was looking out with such a nostalgic smile. “I remember the last time I was atop this mountain, it was to hide Grogar’s bell for sale-keeping. I never thought I would have another chance to come back up here.”
Twilight smiled, taking a moment to look out at the stunning view with a nod of her head. “Yeah, I get what you mean,” she said while struggling not to shiver. “H-Hopefully we won’t need another reason like that to come back here someday.”
“Don’t worry, I have the bell in a much safer location,” Celestia assured before looking back at her. “Besides, it’s nice to have this place reserved for something less… fate-determining.”
Twilight wanted to chuckle at Celestia’s word-play, understanding her point well enough to nod her head. However, the younger Princess couldn’t help pointing out, “Well, I mean… what we’re doing sorta will be, isn’t it?”
“Hmph~” Celestia looked over at her protègè with a cheekier-looking smirk. “Only if you don’t feel confident enough in your own abilities, Ms. Sparkle~”
That remark was spoken with enough inflection to make Twilight blush profusely. She tried to cover her flustered expression with the wool cap she had stashed in the pocket of her jacket. But just as she was about to put it on, Celestia lit up her horn with a bright, flickering glow to catch her attention. “But first,” she said with a tilt of her head that matched her piqued grin, “I feel like we need to make some accommodations for the sake of both our comfort~”
Celestia closed her eyes, and gave her horn a bright flash of her magic before Twilight could speak. Much to her surprise, both she and Celestia were slowly lifted up from the snowy ground they were standing upon. Both of their coats were pulled off of their bodies, and Twilight gasped sharply from the intense cold that struck her bare body for a split-second. But when Celestia’s golden aura of magic brightened around their forms, the blistering cold was instantly casted aside to leave both of them in a bout of gentle, comforting warmth.
Both of their coats of fur illuminated brightly within Celestia’s veil of magic, very similar to the transformation Twilight Sparkle felt when the Crystal Empire was first liberated. As Twilight’s fur illuminated like shimmering crystal, her nerves began to numb with an alluring sense of warmth that swept across her entire body. Even when she was floated back down to the freezing snow, her bare hooves didn’t sense any discomfort or stinging pain like before. Twilight had to look around in awe as powdery snow blew past her at blistering speeds, only to feel like nothing more than a gentle breeze on a pleasant spring day. By the time she glanced back at Celestia, the Alicorn was smirking confidently as she let the magic dissipate from her horn.
“Just so you know, this spell will only last for a few hours at most.” Celestia trotted over towards a large boulder nearby, not minding the cold in the slightest without her coat on. “Of course, depending on how successfully things go, we’ll likely be back down at ground level by the time that happens~”
Twilight may have been grateful to have the elements ignored via magic, but she still gulped audibly with a heavy blush on her cheeks. Even if she didn’t have to worry about the cold anymore, that didn’t change the fact that there was still more to be done. When Celestia returned from the boulder, her horn was lit up again to carry something large in her golden aura. When she saw the wide-eyed expression Twilight was carrying, clearly surprised by the item she was floating with her magic, Celestia couldn’t help giggling to herself all cheekily. “What can I say? I decided to take a page from your book and come about this prepared…”
Much to Twilight’s surprise, she could only watch as the Princess lowered a large, X-Framed piece of metal down at the peak of the mountaintop. For most ponies down below, they likely wouldn’t recognize what that piece of equipment was at first glance; and even the ponies who would know what it was -- most likely from various… mature sources -- wouldn’t likely equate it as being something a member of Royalty would be in possession of. Heck, the only reason Twilight knew about the device was because of Rarity’s dirtier novels she kept out of Sweetie Belle’s possession. But as she saw that large metal frame being erected by her very mentor, the only thing that could go through Twilight’s head was a strong, overwhelming sense of guilt from her heart racing in anticipation.
“Don’t worry, Twilight,” assured Celestia by the time she got the framing secured in a standing position. “I already had this tested myself, and I know how to get out of the restraints if it’s an emergency. I promise you, this will be just as safe as any other method.”
Twilight chuckled nervously while averting her eyes from the Alicorn. “W-Well, that’s good to hea--Wait a minute, how did you test it?!”
Twilight immediately looked back at the Princess wide-eyed, causing Celestia to giggle and shrug her head. “Welllllll…” She rolled her eyes nonchalantly and replied, “Let’s just say, Cadance isn’t known as the Princess of Love for nothing~”
“W-WHAT?!” Twilight’s eyes nearly bulged out from her skull. “B-But… But she’s your niece, isn’t she?!”
“Well, not by blood relation,” she retorted with a matter-of-fact tone of voice. She then shot Twilight a knowing smirk before adding, “Which is more than I can say for you and that ‘Anniversary Present’ with the couple~”
Twilight gasped with a hoof over her mouth. Even if she didn’t say anything regarding that night, her bug-eyed look made it obvious she didn’t expect Celestia to know about it. The mentor narrowed her eyes on Twilight with another chuckle, not needing to say anything more for context. When Twilight finally managed to open her muzzle to speak, her voice came out rather feebly. “H… H-How do you know about that?”
Celestia merely huffed with a confident grin, and replied, “I didn’t. But thanks for confirming it yourself~”
“Ugh!” Twilight face-hoofed with a tight grimace, not believing she fell for that. Fortunately, Celestia didn’t seem too upset as she lit up her horn again.
“Oh, don’t worry, Twilight. When you’ve lived as long as myself or Luna, I can guarantee that you’ll have much wilder experiences than some incestuous three-way~” As Celestia floated out a large duffle bag from behind the boulder, she paid no heed to the embarrassed expression Twilight was carrying behind her blush. While she may have known what was going to occur, it was still jarring for her to hear Celestia speaking so casually on inappropriate matters. Of course, considering how the two were out in one of the most isolated regions in Equestria, it wasn’t like either of them had to worry about anyone eavesdropping.
Well, possibly Discord, but Twilight knew for a fact that he was on a date with Fluttershy that night.
“W-Well, ummm…” After taking a moment to process Celestia’s un-Royal statement, she barely noticed when that duffle bag was floated down to rest beside her hooves. “... I suppose I should be grateful you’re not judging me or anything.”
“Well, of course I wouldn’t judge!” With everything in place, the Alicorn went towards the metal frame herself while speaking to her protègè. “If anything, it’s a little relieving to know you can do those things. Otherwise, this whole process might be much harder for you~”
With that last remark, a heated huff escaped Twilight muzzle. She hung her head in an attempt to conceal her blush, but it was obvious that her mentor’s demeanor was starting to get to her. Meanwhile, Princess Celestia was already standing up on her hind-legs, and stepping backwards into the bottom rungs of the metal framing. Due to how wide the hoof-rests got at the bottom, Celestia ended up standing with a rather wide gait when she leaned back against the metal. Twilight’s eyes widened when she saw her mentor’s suggestive position, and she had to turn away to keep from staring at anything too exposing.
“Now, come on, Twilight~” Celestia’s tone of voice turned quite a bit cheekier, as if putting herself in the restraints was helping her inhibitions loosen a little. She lit up her horn to fasten her hind-legs to the latches on the frame, and then brought her forelegs out to place against the top rungs. “We already agreed to do this back in Canterlot, didn’t we?~”
“Nnnghhhh…” Twilight couldn’t look over at the Alicorn’s restrained state, mostly because she didn’t want to accidentally glance down at that marehood being put on full display between her outstretched legs. Nevertheless, she still tried to respond with a blunt-sounding, “Y-Yeah, I know how this is supposed to go. A-And… And I can understand why you feel this is a valid test, I really do.”
“Do you?” Celestia kept a suggestive smirk while latching her front hooves to the frame with her magic, leaving her completely restricted on the top of Mount Everhoof. “I seem to recall you having apprehensions about proving your worth as the next Ruler of Equestria by such… taboo means~”
After a quick huff through her nostrils, Twilight tried to say, “Yes, b-but I also understand the importance of… of doing something that can be daunting for the sake of trust.”
“You say that,” remarked Celestia, as she fidgeted a little in her restraints to make sure she was comfortable. “Yet, you seem hesitant to even look at me before we begin~”
Twilight’s eyes clenched shut as she struggled not to wince. Even though she understood the significance of this “endurance test,” she couldn’t deny that Celestia wasn’t wrong. Even now, when she was just about to undergo this trial to prove her worth, her heated blush was enough proof that she was feeling overwhelmed. This situation may have been unbelievably unorthodox, even to the point where Cadance and Luna were the only others aware of this procedure taking place. But after breathing out as calmly as she could, Twilight reopened her eyes and turned her attention towards Celestia. “W-Well, excuse me for not wanting too--EEP!!”
The instant she turned to see Celestia tightly restrained in her bondage, Twilight covered her face with both hooves out of instinct. Celestia let out an amused chuckle, but she didn’t look too surprised by such a reaction. Given how long the two had known each other, she was sure that the reveal of her exposed marehood would be quite a thing for Twilight to see for the first time. Nevertheless, the Princess didn’t show any shame while keeping her legs spread wide-apart, revealing her Royal pussy completely unobstructed.
“Hmph~” Celestia narrowed her eyes on Twilight, and asked with a sultrier purr, “Quick question… How do I look in comparison to Cadance?~”
“Ugh!” Twilight didn’t want to appear too disgusted by such a question, but she was quick to roll her eyes and point out, “That’s kind of a personal thing to ask, isn’t it?!”
“Yes, I suppose so…” Since she was lying completely bare on the X-Frame with her hooves restrained, all that Celestia could do was motion her head down at the duffle bag beside Twilight. “Although, your frustration might make it easier for you to start without much hesitation~”
Despite her truthful point, Twilight could only roll her eyes before turning her attention to the bag by her hooves. In an effort to try and ignore Celestia’s coy smirk (as well as those plump, glistening lips that were winking between the Princess’ legs), Twilight opened the duffle to see what her mentor packed. Her blush deepened while perusing through the items, recognizing many of them as the standard array one would purchase at any adult novelties shop. She wanted to question how a mare as regal as Celestia could acquire things like dildos, butt-plugs, vibrators or ball-gags without being on the front page of every tabloid in Equestria. But then again, considering how Cadance apparently helped her Aunt with this, Twilight had to guess that her sister-in-law assisted with the contents of this bag as well.
“S-So, ummm…” Twilight gulped with apprehension while rifling through the various sex toys for her first selection. “Do you have any preferences, or…”
Before she could finish her awkward question, the Princess was thankful to hear Celestia respond with that same assuring tone. “Twilight, the purpose of this test is to try and overwhelm me as efficiently as you can. If you’re able to outlast my endurance, you’ll prove yourself to be an adequate ruler to take over. However you choose to do so is completely up to you~”
Twilight nodded with a brief huff, choosing to keep her muzzle shut and avoid any brash statements. Part of her wanted to assume that her mentor was just wanting to get her rocks off with Twilight’s assistance, but she didn’t dare speak up about such an opinion. In a weird way, the process sounded like a feasible means to prove herself as a worthy successor. Or maybe, Twilight just wanted to think of it that way so it wouldn’t be too weird. Either way, it didn’t take long before her horn lit up, and she pulled out several choice items from the bag.
“Ooh!~” Celestia’s brows rose with intrigue when she saw what was hovering in her protègè’s aura. If it was anypony other than Twilight holding those items, she likely would’ve been a little worried about her personal safety. But considering how much she trusted the Alicorn, all that Celestia did was shoot her a curious smirk. “Interesting choices there~ I’m guessing you really want me to feel helpless, huh?”
“Well, we might as well~ Heh heh heh…” Twilight tried to respond as suggestively as she could, but her chuckle still sounded a little nervous. Fortunately for her composure, she was happy to see her mentor wasn’t upset about the magic inhibitor ring in her possession. Twilight was also holding a bright red ball-gag, and a black blindfold to add to the proceedings. As she trotted up to the Alicorn with her equipment, she took a breath before asking, “So, ummm… Do we need any safe words before we start?”
Much to her surprise, Celestia was quick to shake her head while keeping her randy grin. “Don’t worry about me, Twilight. I have more than enough trust that you’ll know my limits, as well as your own.”
Twilight sighed with a more contented smile, and nodded before floating up her items. The first thing she did was slide the metal inhibitor ring down Celestia’s horn, latching it tightly around the base; Celestia grunted a little when she felt the tight pressure around her appendage, leaving her unable to use any magic herself until everything was done. Twilight then wrapped the blindfold over her eyes, leaving Celestia to shudder antsily and bite her lip. As soon as she breathed out shakily, she opened her muzzle up before Twilight could ask. The younger Princess was blushing hard while placing the ball-gag in Celestia’s mouth, making her appear as helpless and submissive as Twilight’s most depraved fantasies. Before they could do anything else, Twilight made sure to ask, “Are you able to breathe alright, Princess?”
Celestia gave a strong nod of her head, and said muffledly through her gag, “Mmhmm~”
“Alright, good…” Twilight then floated over a bright pink stress-ball, which she placed in Celestia’s right hoof. “If anything gets too intense, or if you need to be let out, I want you to drop this ball, alright? Otherwise, keep a tight grip until we’re done~”
Celestia gave another nod, happy to hear Twilight taking precautions despite her assurances. She did as she was told, and held onto the foam ball tightly in her hoof. Meanwhile, Twilight floated the duffle bag closer to herself and Celestia’s bondage. She reached in to find an adequate tool for their fun, making sure to use her hoof so she could move items around audibly. Celestia squirmed a bit as she overheard the noises of metal, rubber and silicone items being moved around, unable to know what her protègè was going to use first. Eventually, Twilight grew a more intrigued grin as she found a particularly large tool at the bottom of the duffel. “Oooohhh… Celestia, did you happen to look through this bag yourself?”
Celestia shook her head, since she couldn’t clarify that Cadance prepared the bag for her as a surprise. “Nnn-Nnn~”
“Lovely~” Twilight knew that it was tricky to bring out something so heavy-grade as the first item, but she knew better than to start small with someone like Celestia. When she pulled the large rod of white plastic from the duffel, which had a thick rubber bulb at the tip, Twilight was surprised by how heavy it felt in her hoof. She inspected the item for a moment, never having held a Hitachi wand before now. However, the moment she flipped the switch on, and she felt the sharp pulsations of its motors humming strongly in her grip, Twilight couldn’t help shuddering with an antsy grin. “Oooh!~ I need to get myself one of these sometime…”
“Mmmmmm…” The instant she heard that familiar buzzing, Celestia tensed up in her bondage with a muffled moan through her gag. Twilight chuckled a little when she glanced back at her mentor, not minding that the surprise was promptly spoiled. Instead, she went up to the Princess while holding her device, and kept it on so the rubber bulb pulsated loudly at the tip. As she brought the toy closer to Celestia’s nethers, her smirk grew more curious as she saw how much the mare’s thighs tightened up in anticipation. Moreso, her eyes eventually focused on the sight of Celestia’s exposed, supple pussy winking while the lips were spread apart.
“Nnnffff~” Twilight had to clench her own hind-legs for a moment, not expecting to get so overwhelmed by the mere sight of that Royal marehood. Even though she always carried a deep sense of admiration and respect for Celestia, she’d be lying if she tried to admit she never harbored any feelings of attraction either. While she never admitted it to Celestia personally, there was even a time in her life when she felt even stronger feelings than that; although, most of those feelings dissipated shortly after Shining Armor’s wedding, when she was still trying to regain the trust of her friends and mentor after that rehearsal. Nevertheless, even with how complicated their past may have been over the years, Twilight was comfortable enough nowadays to appreciate the sight of Celestia’s loins without much conflict. Was it weird to see her mentor’s wet, winking pussy up-close? Yeah, it certainly was…
But was Twilight willing to take advantage of Celestia’s bound state, and play around with that pussy for her own perverted personal use? Absolutely~
Twilight turned up the dial on the handle of her device, causing the Hitachi wand to buzz louder like a swarm of hornets:
VRRRRRRRRRRRR…
“NNNGHHH!!~” Celestia was reeling tightly in her bondage, and she leaned her hips outward in an attempt to feel that loud device in a more appropriate way. However, much to Twilight’s delight, it seemed that the mere sound of that Hitachi wand was enough to tense Celestia up. Since the Alicorn couldn’t see it through her blindfold, her sensory deprivation was already proving to be useful as she waited for her protègè’s next move. However, even as she heard that device pulsating closer towards her nethers, her poor cunny was left untouched while Twilight snickered to herself devilishly.
“Wow~ I have to admit, I wouldn’t have expected a single sensory response to elicit such a reaction for you…” Twilight tilted her head curiously as she watched how much Celestia was writhing in her bondage, clearly wanting for her former student to take proper action. But instead, the young mare kept an upbeat tone while teasing her in a scientific manner. “Hmmm… I wonder if I can make you orgasm without even touching you? There are definitely some variables I could test to see if such a feat is possible. Not to mention, you’re already growing pretty wet from th--”
“MMMFFFFFFF!!~” Celestia interrupted her egg-headed analysis with an impatient moan, and shivered needily for that buzzing to be accompanied with something else. Unfortunately, since Twilight was taking the reins without any restrictions, that muffled groan just made her smirk more confidently.
“Now, Celestia…” Twilight carried a firmer tone as she addressed the Alicorn by her first name, not showing any hesitancy through her amused smile. “You know that you can’t stop me, right? That’s the whole point of this test in the first place. I get to do as I please with you, and you have to try and last as long as you can before giving up~”
“Nnnnnghhhhh…” Celestia was beginning to test the sturdiness of her restraints, and tensed up greatly from the cockiness in Twilight’s tone. Even though this wasn’t what she intended with this test, she couldn’t deny that the Princess was certainly making her squirm. With the way her fur was standing on end across her thighs, it seemed like she was reacting to the wand’s buzzing like she was expecting a bee-hive to be hovered in front of her. However, Twilight was more focused on the Princess’ supple, alluring pussy as it began to drip from her growing lust.
With every strong gyration of Celestia’s hips, trickles of her arousal began to drip down the inside of her spread-open thighs. Her flawlessly white fur was becoming matted from the added moisture, which thankfully didn’t freeze in these extreme climates due to her magical precautions earlier. Because of that, Twilight couldn’t help shuddering when she saw that cunny growing wetter, and the sweet musk wafting from Celestia’s nethers became more notable with each passing second. She licked her lips while trying to stifle a moan, not wanting Celestia to hear her growing as heated as she was. But at the same time, Twilight used that feeling to her advantage as she grew an antsy shudder alongside her lustful grin.
“I must say, you’re starting to sound really anxious right now…” Twilight had to keep from giggling after that taunting remark, which elicited a heavy moan through Celestia’s ball-gag. The Princess was squirming hard in her tight restraints, and her hips continued to reel outward in an attempt to make contact with the Hitachi wand. Twilight made sure to keep the toy just out of reach of that dripping pussy, even when she saw Celestia’s fat clit beginning to pulsate out of eagerness. While her dominant hoof held onto that plastic toy to keep her mentor nice and tense, Twilight grinned when she lit up her horn for something else. “Well… Perhaps you should feel something else first~”
With that, Twilight Sparkle caused the Alicorn to belt out a muffled shriek when she pressed the head of a fat, hot-pink dildo right against those winking lips.
“MMMMMMPHHHHH!!!~” Due to how overwhelmingly hot she was getting, Celestia reacted to that rod of silicone like her protègè had just set an electrical charge against her clit. The plump bulb of the dildo’s end prodded against Celestia’s supple lips, causing them to quiver and drip more incessantly. She let out a hungry moan as she tried to push herself against the toy, but was only able to slather the head in her sweet, syrupy juices without much penetration. Twilight was still keeping her Hitachi wand buzzing loudly for added titillation, but seemed content with playing with the Princess by manual means first.
“Mmmmmm… You want that in you, Princess?~” Twilight was growing more comfortable with her position over Celestia, even as she shivered in a mixture of surprise and elation. Even with how many times she guiltily fantasized about herself and Celestia in varying ways, she never would’ve fathomed she would have the Princess in such a submissively hot position now. The sight of that muzzle drooling over her ball-gag, leaving her lustful moans silenced throughout her titillating torture, was pressing buttons that Twilight never knew she had herself. She was starting to cherish those cute, muffled noises Celestia was trying to make, and her magic gave a brief contortion as she dug the dildo in deeper. “Well, let’s see how much you really want it~”
“MMMMMMFFFFFFFF!!~”
Despite how loudly Celestia tried to belt out through her gag, Twilight shuddered from the sound of that wet schlick that came with the dildo’s head making penetration. The smooth, plump silicone slid its way between the Princess’ hungry lips, finally opening her up to leave her wailing in her restraints. More of Celestia’s dripping arousal began to coat the toy more prominently, with a couple droplets trickling down the length of that hot pink shaft. Twilight knew that she should’ve taken her time, making sure to tease the Alicorn as relentlessly as possible to prove her merits; however, the sight of Celestia’s clit throbbing intensely was leaving the younger Princess eager to push her limits.
“Nnnnghhhhh~” Another hot shudder crept across Twilight’s body, as she dug that thick toy further past those lips to fill Celestia right up. While the dildo slid in deeper with each push of Twilight’s magic, Celestia continued to moan out like a showmare in heat. The toy’s smooth, albeit girthy shaft was provided with more than enough lubrication as the Alicorn continued to drip incessantly, coating the silicone in her juices so it would glide snugly against her lips. Meanwhile, Twilight finally decided to bring her Hitachi wand into play, as she teasingly pressed the pulsating bulb right above that marehood to buzz against her waist. “NNNNNNFFFFFF!!~”
“Ooh, somepony’s getting antsy~” Twilight giggled like a schoolfilly as she continued to toy with Celestia’s prone state. Trickles of the Princess’ dripping arousal were coating every inch of the dildo with her juices, even though only the head and a couple inches had slipped their way through. Her fat, glistening lips tried their hardest to hug around the girth of Twilight’s toy, but the silicone proved to be too smooth to gain any friction. Even with how badly she wanted to hold onto that dildo with her hungry pussy, more of that length pushed its way through like a hot knife through butter. Due to how easily she was able to slip her way through, Twilight couldn’t help chuckling with a taunting grin up at her. “I gotta say, it’s surprising how effortlessly I’m able to get this toy inside. It’s almost like you’re too loose to really hold onto it~ Is there something you’re not telling me, Princess?”
“MMMMFFFFFF!!~” Celestia wasn’t able to speak out while her muzzle was plugged with that ball-gag, but she tried her hardest to moan out in response to such a claim. But alas, Twilight continued to push that toy in deeper with her aura. Meanwhile, her wand was still buzzing loudly while the bulb dragged across Celestia’s body, touching every region of her loins except that needy pussy.
“Hmmmmm… I bet there is a reason, isn’t there?~” Twilight knew that this kind of dialogue was extremely unbecoming of a Princess, but it wasn’t like Celestia could do anything about it right now. Not to mention, a little verbal teasing wasn’t really that big of a deal while she was stuffing that Royal cunny with a fat dildo. The young Princess’ grin grew more obscene, and she took her time dragging the Hitachi wand closer to her wet and stretched-out slit. “Tell me, ‘Princess’ Celestia… are you usually this loose when you get so riled-up? I would’ve expected somepony as proper as yourself to be a little tighter~”
With that last inflected word, Twilight gave an especially hard push so a couple inches slid inside at once. Celestia wailed out a heavy moan through her gag, unable to stop her pussy from hungrily swallowing up more of that dildo like it was nothing. Twilight shivered in perverted delight, rewarding the Alicorn by dragging the wand a little closer to her needy clit. But since Celestia wasn’t able to see what she was doing, Twilight grew a heated blush as she leaned her muzzle in, and stuck out her tongue at the end of that hovering dildo.
“Aahhh!!~” Twilight closed her eyes with a brief moan, and lapped up a small amount of the arousal dripping down the length of Celestia’s toy. The Princess tasted absolutely delectable, carrying a sweetness that mirrored some kind of fruity nectar. The consistency was thick enough to coat Twilight’s tongue, causing her to shudder wildly from that warm and syrupy sensation. Without even thinking, Twilight bent in further to drag her tongue across the dildo’s shaft, and moaned out from tasting even more of her mentor’s hungry muff. “Nnnnnnnnnn…”
Twilight finally pulled the hitachi wand down just enough to barely grace against Celestia’s clit. The vibrations alone were getting to Celestia when they were just gracing across the top of her writhing hips; but the moment she felt those sharp pulsations against her already throbbing clit, the sensation was sudden enough to make her hips jerk forward in dire elation. “MMMMMGHHHH!!!~”
Without warning, a thick spurt of her juices spat out from around the girth of that dildo, landing right across the bridge of Twilight’s snout. She reeled back all wide-eyed, clearly not expecting for her mentor to also be a squirter among other things. The thick, overwhelming scent of Celestia’s musk caught her off-guard, and she couldn’t help shivering with a deeper moan while her eyes grew half-lidded. The Alicorn was so surprised by that sudden jerk of Celestia’s hips, that she needed a moment before realizing her thrust shoved a couple more inches of the dildo through those lips.
“Oh, my~” After breathing out shakily, Twilight’s confident grin returned as she resumed her efforts. Since Celestia had swallowed up so much of that dildo without question, Twilight moaned out from the sight of those fat pussy-lips being stretched so prominently around the thick base. Her Hitachi wand continued to buzz loudly, but she kept the grip tight in her hoof so it wouldn’t press down any harder against that needy clit. Even though she would’ve loved to make the Princess squirt some more, Twilight wanted to continue her taunting to really make Celestia squirm.
“Hmph~ No wonder you needed a successor to take your place at the throne…” Twilight knew that this kind of dirty-talk might be a little much, but her tone of voice remained confident while twisting that dildo with her magic. A needy shriek erupted around Celestia’s gag, but she wasn’t able to do anything while feeling every inch of that thick silicone rubbing against her sensitive regions. Her lips tried to cling around that toy in hopes of keeping it still, unable to handle the titillating grinds it made against her folds. But due to how much she was dripping incessantly, all that her arousal did was allow for the toy to slide around easier inside of her. Twilight knew that fact just as well as her mentor, and she wasn’t afraid to keep pushing like a good Mistress. “Nnnffff~ You really are a naughty mare, aren’t you? You had an entire nation at your hooves, but right now you’re just wanting to get a bigger stretch, don’t you?~”
“NNNNNNN!!!~” Despite how mercilessly she was being teased, Celestia was growing far too horny to give two shits. Her hips continued to buckle with each gyrating motion or thrust she felt from Twilight’s toy; however, it did nothing to get that vibrating bulb of the Hitachi wand closer to her waiting button. Her nerves were tingling on end, unable to properly handle all these tantalizing sensations without reeling in her restraints. But even with how helpless she felt in her submissive state, all she could think to do was nod her head in response to Twilight’s question. “MMHMMM!!!~”
Twilight grinned even more devilishly. “Good girl~”
VRRRRRRRRRR!!!~
The Hitachi wand finally made full-contact, pressing down firmly against Celestia’s clit while her pussy was filled with that thick rod of silicone. The Alcorn cried out helplessly through her gag, with her muffled voice echoing out far from the mountaintop; of course, nopony was able to overhear her while she hugged that dildo as tightly as she could. Her hips buckled like mad against the strong gyrations of that pulsating bulb, which stimulated her nerves badly enough to feel like she was being electrocuted by her perverted protégé. But despite how badly she was reeling from every inch of her body, Celestia kept an iron-tight grip on that stress ball so Twilight could keep going.
“Nnnnghhh!!~” Twilight was groaning through gritted teeth, absolutely loving how much she was toying with her mentor. Much like the bound Princess, who was dripping badly enough between her legs to leave both thighs completely matted in her juices, Twilight had to shudder a little as she felt her own tail flagging up involuntarily. Considering how wet the younger mare was getting from Celestia’s titillating torture, she was feeling far more grateful about that spell leaving her impervious to the cold; otherwise, she would’ve been worried about her pussy being frozen shut from how much she was leaking in this freezing climate. But instead of trying to tend to her own arousal, Twilight remained solely focused on that hot, dripping cunt she was playing with in front of her.
“Mmmmphh… You’re really getting into this, aren’t you?~” she asked tauntingly, just before slipping another inch of that dildo inside to make Celestia groan through her gag. “Yeah, that’s what I thought~ I bet you’re just begging for more…”
Twilight may have not been an expert when it came to acting like a Mistress, but she was grateful that her dialogue was keeping her mentor squirming elatedly. When she pressed the bulb of her wand down harder against Celestia’s clit, the Alicorn’s body writhed intensely with a strong shiver against her restraints. Celestia’s hungry lips clenched hard around that hot-pink toy, nearly sucking it in entirely from Twilight’s magic. But while the younger mare kept a tight grip on that dildo, she ended up moaning out from the sight of another heavy spurt of Celestia’s juices spitting out around the base.
“Nnnnghhhh!!~” Twilight bit her bottom lip tightly, but maintained her resolve enough to keep going. Even if Celestia was squirming with a lumbering moan in her bondage, that orgasmic response wasn’t enough to warrant her stopping. After all, Twilight was able to see that she was still holding onto that ball tightly, even as the Hitachi wand kept buzzing like mad against her clit. Her breaths were growing more rapid, but she kept her resolve to ensure that Celestia wouldn’t have a chance to catch her breath. Even after the base of that dildo was completely soaked in her juices, and those plump lips quivered badly from that post-climactic release, Twilight kept twisting that toy deep inside of the mare while her clit was being bombarded with hefty pulsations.
“Yeaaahhhhhh… You like that, Celestia?~” Twilight tried to keep her voice from sounding too fidgety, even though she was feeling nearly as riled-up as the Princess she was playing with. Part of her wanted to tank off Celestia’s ball-gag, just so she could lunge up and make out with her while giving that pussy a much-needed pounding. Heck, Twilight almost wanted to yank her dildo out without warning, and eat out that Royal cunny to taste more of her syrupy sweet juices. But alas, even as she shuddered antsily with her pussy growing wetter, Twilight instead used her Hitachi wand to drag the bulb all around Celestia’s oversensitive pussy.
“NNNNNPHHHHH!!!~” Even after squirting like a little bitch, Celestia continued to wail out in heated pleasure as those sharp vibrations titillated her all over. Every hard drag of the rubber bulb against her sensitive flesh was leaving her reeling mindlessly, with her lips hugging the girth of that dildo as needily as she could. More of her arousal was practically gushing from her burning nethers, raining down between her legs like a filly who wet herself in class. Even the wand in Twilight’s hoof was becoming drenched in the Alicorn’s juices, which prompted her to suck in deep breaths of that sweet musk while her snout was so close to the action.
“Aaaaahhhhh…” Twilight brought up her hother hoof, and grasped the base of Celestia’s dildo to start pistoning it manually. Celestia let out a rumbling groan as she felt her protègè sliding that thick toy out, until only the cockhead was tightly pursed between her lips. Twilight didn’t hesitate before shoving that toy right back in, eliciting an even deeper moan from the bound and gagged Princess. Just like that Hitachi wand in her dominant hoof, which she was taking her sweet time grinding around Celestia’s dildo to titillate every square inch of her quivering pussy, Twilight’s hoof-work remained vigilant as she vigorously started to pump the toy in and out of her hungry cunny.
“Mmmmmmm…” Twilight licked her lips sensually before moaning out, “You better cum for me again, Princess~ Otherwise we’re gonna be up on this mountain for a while…”
“Nnnnnnnn!!!~” Even though such a fate wasn’t nearly as threatening as Twilight would’ve hoped, Celestia was still reeling blissfully while sinking deeper into depraved pleasure. The constant vibrations and gyrations she was experiencing were leaving her mind as frayed and overwhelmed as her tingling nerves. With every hard pump of that dildo inside of her, as well as the wand’s constant tantalizing pulsations across her sensitive pussy, Celestia remained tightly tensed in her bondage as her arousal remained at a steady peak. Instead of coming down from that orgasmic high she experienced earlier, her body remained rigidly tense to endure more of her successor’s diligent torment.
“C’moooonnnnnn, Celestia~” Twilight was just as eager to keep things going as her mentor, and didn’t even brush off any of the snow blowing through her fur. Instead, all of her focus remained on Celestia to ensure she was going to remain in a perpetually pleasured state. “I know you can give me another. You better do it now before I get out a camera~”
“MMMPHHHHH!!~” Celestia was caught by surprise when her body locked up, and her pussy clamped hard around that dildo in Twilight’s grip. Another heavy torrent of her arousal drooled out from around the toy’s girth, coating Twilight’s hoof with her sticky secretions to indicate how much she was getting to her. While she seriously doubted Twilight would actually bring out a camera during this private session, the titillating threat was more than enough to make the levees crumble once more. Another hefty torrent of arousal swept across her body, which resulted in Twilight’s hoof becoming even more matted from her secretions. Her legs couldn’t stop squirming, which made the incessant dripping more erratic all over the ground. Celestia wasn’t sure how much more she could take. But with the aid of that ever pumping toy, as well as the wand swirling about more furiously with the bulb vibrating like crazy, Celestia could even get a moment to breathe through her gag.
“Aftercare comes after we’re finished,” growled Twilight with a more devilish voice. Her grin widened immensely, and her focus bore down more on making the Princess squirm like a fish out of water. “And believe me, you naughty little ‘Princess’... we’re not gonna finish until you drop that ball~”
Another hungry moan belted out through Celestia’s gag, but she didn’t relent in the slightest. Even after orgasming twice from Twilight’s tenacious toy-play, the Alicorn was keeping a tight grip on that stress ball in her hoof. Twilight nodded in approval, not seeming too upset to continue her fun with the Princess-turned-fucktoy. Instead, all that the successor did was give her a hungry grin before saying, “That’s what I thought~”
“NNNNNGHHHHH!!!~” The instant Twilight gave that response, the sudden jab of her dildo deep into Celestia’s cunt left her wailing out in blissful torment. Her pussy was already tingling badly from even the slightest touch, still quivering from the constant stimulation that came from orgasming back to back without much pause. But despite how sensitive her spent and dripping marehood may have felt, Celestia wasn’t given any reprieve as Twilight continued to thrust into it vigorously. Her hooves were working overtime, and the repeated bouts of penetration were only intensified as she upped the dial of her Hitachi wand. Much to Celestia’s shock, and Twilight’s perverted delight, the bound Princess only learned then that she wasn’t using that wand at its maximum voltage.
VVVRRRRRRRRRRRRRR!!!
“NNNNNNNNNN!!!~” If Celestia wasn’t wearing a blindfold, Twilight would’ve likely only seen the whites in her eyes from how badly they were rolling back. Of course, if Celestia had the ability to see herself, she would’ve noticed how eagerly Twilight was grinning as she treated her pussy like her own personal plaything. Sweat was starting to bead down the Princess’ face, despite being out in subzero temperatures without any clothing on. But due to Twilight’s determination (as well as Celestia’s earlier spell for their personal safety), she felt unbelievably hot while kneeling between her former mentor’s legs.
“Jeeze, you... you’re really trying to keep your own, aren’t you?~” Twilight’s words may have been a little spaced due to her heavy panting, but her voice was still dominant enough to catch Celestia’s attention. The Alicorn was writhing mindlessly in her restraints, barely able to give any response save for a faint nod of her head. Unfortunately for her, Twilight’s grin only widened as she narrowed her eyes up at her gagged and blindfolded face. “Well… It’s not gonna be enough to keep me from taking you down~”
If Celestia was able to speak, or even think coherently enough to give a response, she likely would’ve reminded her that was the point of all this happening in the first place. But since her poor cunny was being mercilessly toyed with by Twilight’s constant titillation, the only thing running through Celestia’s mind was how much longer she could last. Even now, as her legs were writhing like crazy from being pushed over the brink multiple times, her nerves were still tingling like she was remaining perched at the very precipice of release. It was almost shocking that Twilight didn’t try to implement any orgasm spells, which would’ve been more than enough to leave her relentlessly overwhelmed with pleasure all night. But then again, given how tenaciously she was using her hooves to use those toys to the best of her ability, Celestia couldn’t have been prouder of her successor’s due diligence. Sure, she couldn’t necessarily think while that dildo was ramming itself in and out of her dripping cunny, and that Hitachi wand was buzzing hard enough to keep her clit continuously pulsating in tantalizing bliss; but at the same time, she was sure that her constantly-drooling arousal was more than enough for her former student to know her efforts were appreciated.
High above Mount Everhoof, the hungry moans of Princess Celestia could be heard from miles off in the distance; of course, since she and Twilight were the only living beings able to reside in that region, neither of them cared in the slightest about the risk of being caught. No birds were able to fly up high enough to see them, and Luna was too preoccupied with her dream duties to take notice of her sister’s antics. Instead, the only things that were around to witness the perverted Princesses were the heavy gusts of snow from up above, and the thick cloudlines down below.
…
… Well, that, and perhaps the presence of a certain draconequus and his date lounging in a protective bubble high above Celestia’s bound state.
Discord was seated on one end of a plush loveseat, happily munching on a bowl of popcorn and watching the spectacle down below. Right beside him was his date, who was sporting a very heavy blush across her cheeks while covering her mouth with both hooves. Even though she couldn’t necessarily speak about her friend’s actions without sounding like a hypocrite, Fluttershy still looked rightfully flustered by the sight of Twilight pumping Celestia with a dildo. Since she was too overwhelmed to really speak up, Discord broke the silence after sipping a martini. “Aaaahhhhh… And to think, you just wanted to stay home and watch a movie~”
“W-Well, ummm…” Fluttershy couldn’t say much in regards to her date’s remark, since she had to readjust herself in the loveseat multiple times since Twilight’s “test” began. But after huffing to herself feebly, she tried to point out, “T-To be fair, I… I wasn’t expecting this when you offered us to see a ‘Once in a Lifetime’ event.”
“That might be true, but you can’t say I was lying about such a claim.” After helping himself to another clawful of popcorn, he added with a shrug of his head, “Besides, those movies back at home will still be there when we get back. This, however, can’t exactly be replicated.”
Fluttershy looked back at him with a raised brow, and then pointed a hoof towards the camcorder beside his seat. “If that’s the case, why are you recording it?!”
“What, I can’t have a hobby?” Discord then looked back at her with a sly-looking smirk. “Besides, when Twilight eventually throws a conniption about the two of us being an item, I need something to shut her up quickly~”
Fluttershy looked like she wanted to say something, but nothing came out of her muzzle when she brought up a hoof. After a moment, she eventually looked away from him in silence, and shrugged with great hesitancy. During that brief moment, Discord looked back at you, the person reading this very story, and said on a final note:
“Besides, wouldn’t you want a copy of that tape?~”
“DISCORD, YOU SAID YOU WOULDN’T BREAK THE FOURTH WALL ON THIS DATE!”
The End
