Denial

“Are you sure all of this is necessary?” Twilight asked as she gestured to the sealed entrance to Zecora’s home.

The windows of which had been securely plugged, and the door had been covered with a thick plastic curtain lined with tiny hazard symbols. More unnerving still was the way that despite it only mid-day, the sun hardly seemed to shine upon the small grove Zecora’s house stood at the center of. Though this was partially due to the sheer amount of shade that the large trees gave, it may have also just been the oddly serious, almost oppressive atmosphere that hung over them.

Applejack nodded. “If Zecora thinks this whole get-up is required, then it is. Simple as that.”

“It's not like I don't trust her or anything, this all just seems a bit much though,” Twilight exclaimed.

The farm pony shrugged. “It was real potent stuff that you brought her. Enough to keep her up all night just doing calculations based on what the uh, ‘extract’ was capable of.”

Twilight lifted an eyebrow and eyed the earth pony who stood next to her carefully. “It couldn't have been that powerful, right? I mean it's just well, cum.” Twilight remarked lamely.

Applejack blushed slightly and shook her head. “It's not just that. Luna hasn't well, done it in the physical sense for well over a thousand years, and to top it all off, she's a real powerful alicorn.”

“I suppose that's fair, and that we’ll just have to see how powerful the potion is in a moment,” Twilight murmured, before turning her attention back to the door.

As if on cue, the door handle jiggled, and pushed open, forcing the sheet of plastic to be gently shoved out of the way. All in order to allow a robe, and mask-clad zebra to slowly slip out into the open air, her hoof holding a long, thin flask that was capped with a thick black cork. The bottle itself was bound by a very secure-looking stopper, as well as several cloth bands that kept the lid securely closed and tied tightly.

Once outside, Zecora sealed the door behind her before reaching up and pulling off the bird-beaked mask she wore. “That was quite the job. I feel like I could collapse into a blob.” Zecora remarked tiredly.

Applejack assisted the mare in shedding the rest of her thick, cumbersome clothing before gently setting it a fair distance away. “So did it all work like we thought it would?” Applejack inquired.

“Yes, did it work? I admit I am curious if it's as powerful as Applejack seems to think it is.” Twilight exclaimed.

“You can tell our guest more, for I have one final chore,” Zecora remarked, giving her girlfriend a gentle squeeze and balling up her clothes, trotting away.

Applejack nodded. “Right, well if everything went like we thought it would then that means this stuff is super potent.”

“Just how potent are we talking about?” Twilight asked.

Off to the side, Zecora dumped her mask, and clothes into a small pit before starting to pile leaves and twigs over it.

“Well, our estimates placed its potency really high up there, and Zecora thought it would last quite a while.” Applejack tapped her chin. “I think we guessed that it would last for around two to five days at most, though it would depend on the individual.”

“What like their age or tribe?” Twilight pressed.

“Sorta. It's more like if you get off a whole bunch then it won't last as long.” Applejack replied.

“Okay, so it will last multiple days, and masturbating constantly makes its effects not last quite as long. That makes sense, kind of.” Twilight murmured. “Does it have any effect on stallions?”

“None whatsoever.” Applejack quickly replied.

“You said that with quite a bit of confidence,” Twilight remarked curiously.

Applejack blushed. “Well, I may have offered to help with Big Macintosh’s sex life, not like they needed it though. Turns out it did nothing for him, but everything for her. If you catch my drift.”

“Interesting. How hot and bothered are we talking about here?” Twilight inquired curiously.

“Ready to have sex with anyone, and anything,” Applejack stated, only to purse her lips. “Though it's a good thing it doesn't do anything for stallions, otherwise I’d be bucking all by my lonesome for quite some time.”

Zecora tossed a burning branch onto her clothes, and walked over to the pair, throwing a hoof around Applejack’s shoulder. “To the dogs, you would not be thrown, for you would not be alone,” Zecora exclaimed.

Applejack chuckled and bumped her hips against her partner’s. “I like your enthusiasm, but not even you could replace Big Macintosh.”

“I’ll have you know that even though I am slim, I am almost as strong as him,” Zecora stated, the zebra flexing a hoof dramatically, a small smirk on her face.

Applejack rolled her eyes. “Har har.”

“So how much of the stuff were you able to make anyway?” Twilight inquired.

Zecora gestured to her home. “Though I have but the one on me, I have a dozen or more in my tree.”

“Yeah you uh, certainly brought us quite a bit,” Applejack murmured.

Twilight blushed slightly. “Yes, well. Luna was quite… productive.”

“It is also far more potent than the others I’ve brewed. In fact, it makes even Applejack’s release look rather subdued.” Zecora explained.

Applejack blushed and pulled her hat down slightly. “Now why did you have to go and say something like that?”

“Because it's cute when you hide in your hat,” Zecora replied, with a wink.

“So, how potent are we talking about exactly?” Twilight continued. “I don't want it to last forever you know.”

“I assure you this is no curse, rather the effects of it will just be worse,” Zecora exclaimed.

“How bad are we talking about Zecora? I remembered what you were talkin' about the other night, but now that it's actually made surely you got a better idea.” Applejack asked curiously.

“Compared to Sugar Belle, this would be hell,” Zecora stated firmly.

Twilight smirked. “Perfect. This is going to be just what I need.”

“Are you sure about this Twi? That's some real powerful stuff ya got there.” Applejack cautioned.

“Celestia has a will like iron. Trust me when I say that the potency is absolutely necessary to break through that,” Twilight claimed.

Zecora removed her hoof from around Applejack’s neck. “My home will need around a day, I don't suppose you have a place for me to stay?”

Applejack blushed and pawed the ground. “I suppose you could stay at the farm for a little while. Just be wary, Granny Smith doesn't look the type but she does enjoy the odd prank every now and again.”

“Though she may sometimes appear weak, she has quite the mischievous streak,” Zecora exclaimed with a chuckle.

“She does doesn't she?” Applejack mused. “I’m amazed a mare of her age can keep up with us young’uns.”

“I hate to interrupt, but I must be going. Best of luck with the housing situation.” Twilight exclaimed.

Applejack smiled. “Don't you worry none, I’m sure we’ll get it figured it out in no time.”

“Because sleeping out here would be a crime,” Zecora added.

“Thank you again for your assistance Zecora. If there is ever anything you need, don't hesitate to ask.” Twilight added before lighting her horn and beginning to gather magic for a long-distance teleport.

“Don't worry about anything at all, It is worth it to see her fall,” Zecora stated, bowing slightly.

“Give ‘er hell Twi.” Applejack encouraged.

“I will.” Twilight declared before disappearing in a flash of light.

The lavender alicorn stepped into the throne room with a wide smile, having arrived just after the day court had closed. Court recorders, pages, and assistants were still cleaning up the paperwork that would be needed to enact some of the accepted proposals. All the while Celestia stood silently upon her throne, her attention fixed completely on Twilight as she strode towards her.

“Greetings my friend, to what do I owe the pleasure?” Celestia greeted.

My friend, that's relatively new. Twilight thought to herself. “I’ve just come to chat, and test out a new compound provided that you have a moment.”

Celestia paused, no doubt considering her options carefully. “Well I do have some time to myself now, should we retire to my chambers? Or would you prefer a different setting?”

Twilight smiled. “Your chambers would be perfect.”

Celestia nodded slowly. “Then I will meet you there momentarily.”

“Excellent.” Twilight declared before lighting her horn and vanishing in a flash of light.

Sure she could have just walked, it wasn't exactly far, but Twilight was feeling a little excited, and the bottle of arousal poison was weighing heavily on her mind. Would it work, if it did how well would it work? Could Celestia’s incredible will even be beaten? All those questions and more swirled within her mind, bouncing around the inside of her skull without end.

Twilight hopped up onto Celestia’s bed, and sprawled out, getting as comfortable as she could while she waited. Which was something that she didn't have to do for very long, as the door opened only a minute later. A slightly nervous, almost anxious-looking Celestia strode into the room, some of her pride, and confidence having been diminished now that Twilight and her were alone.

When the door closed, and they were truly alone, Twilight cleared her throat. “Is something wrong Celestia?” Asked the princess of friendship.

Celestia shook her head. “It's nothing, Luna seems to be enjoying her toy is all.” She grunted suddenly. “And Cadance is as well.”

Twilight chuckled. “I guess they read my mind.”

“Oh? What do you mean?” Celestia inquired.

“It's nothing.” Twilight quickly replied, before casting a quick spell and recalling the potion from her extra-dimensional space. “Now then, let's get onto the reason I’m here in Canterlot in the first place.”

“Which is what exactly?” Celestia asked, the alicorn switching from hoof to hoof occasionally as she eyed the bottle floating before her.

“This is a new potion I’ve been working on, one that I do believe we will get quite a bit of enjoyment out of.” Twilight declared.

Celestia frowned. “We as in you and I or we as in you, Luna, and Cadance?”

Twilight smirked. “Yes.”

The elder alicorn sighed and tried her best to hide the smallest of smiles from the edge of her face. “Fine then, what would you have me do?” She asked.

“Stick out your tongue please,” Twilight commanded, her magic unscrewing the top of the bottle and retrieving from it a single drop of the swirling blue and black liquid contained within.

The potent scent of arousal mixed with an almost acidic smell which wafted from the bottle, prompting both Twilight and Celestia to squeeze their nostrils shut. Despite the disgusting smell, Celestia did as she was told, sticking out her tongue and bracing herself for contact. Twilight deposited the drop on Celestia’s tongue and took a step back, partially in order to better watch the alicorn’s reaction, but also out of fear.

Celestia smacked her lips and rolled the flavor around her mouth as if she were unsure if she liked it or not. “It almost tastes like Luna, but also like sulfur and dark chocolate at the same time,” Celestia remarked. “It's very strange.”

“Oh, and do you feel any different, by chance?” Twilight inquired, a clipboard, quill, and ink pot flashing into existence.

Celestia paused as she watched Twilight wet her quill and get ready to take notes. “You know, doing stuff like that doesn't exactly fill me with confidence.” She pointed out.

“Well, you are the first person to try it after it's been refined, and has had the base recipe altered slightly.” Twilight pointed out while tapping her clipboard. “So if you could describe the changes as they are happening that would be most appreciated.”

“I’ll try.” Muttered Celestia before suddenly shuddering, and letting out a confused moan. “Oh wow that is… quite intense.”

“Is it a pleasurable experience or perhaps that was an uncomfortable shudder?” Twilight offered, peering intently at the other mare while her face began to screw up into a strange mask of confusion and arousal.

“Intense heat, like I’m burning up from the inside out, but not uncomfortable, just like I said, intense,” Celestia murmured, wincing slightly as she bit her lip. “Why exactly are we doing this again?”

“The compound may be capable of overcoming the denial spell,” Twilight explained, leaving out the part that such a possibility was incredibly unlikely if it was even possible in the first place. “Which is why you shouldn't cast the poison purge spell I can feel you trying to start.”

“R-right.” Celestia stuttered the wisps of magic that had been gathering at her horn dying in an instant. “Are you sure this stuff is safe though?”

“I have no idea, which is why we are testing it on you,” Twilight remarked.

Celestia shuddered again, this time falling to her knees as her body struggled to adapt to the sheer amount of heat coursing through it. “Oh gods, it feels like my first time all over again. Like every heat I’ve ever suppressed is coming back all at once.” Celestia exclaimed before moaning loudly and suddenly.

Twilight raised an eyebrow when she heard something splash against the ground and glancing between Celestia’s legs Twilight found out just what that was when she saw the puddle Celestia had just produced. The smell that wafted from it was intense, almost as if the potion had somehow managed to make the other mare’s juices more concentrated, even though such a thing should be impossible. Peering intently a moment longer, Twilight was able to notice that her former teacher had also begun to suffer some other, less obvious side effects.

Namely, the fact that the other mare’s clit had become so engorged that it was no longer winking, rather it stood prominently on display for anyone and everyone to see. It was an amusing sight, but Twilight tempered her good humor, and made a few notes on her clipboard, trying to keep up the air of professionalism. Something that became increasingly hard to do as she watched Celestia try to stand only to fail to do so several times.

Laying breathlessly on her stomach, Celestia’s legs twitched and her chest heaved, unable to fill her lungs. “You didn't say that, it would work that fast,” Celestia exclaimed between gulps of much-needed air.

Twilight shrugged. “I wasn't sure if it would work as fast as I assumed it would. You are the guinea pig after all.” She pointed out.

Celestia’s groan of irritation morphed into a confused moan, and the alicorn fell to her side, body still twitching as she lay on the cold floor. Twilight made a few more notes, making sure to keep her attention focused on the more clinical aspects of things. After all, she did have a genuine scientific interest in the potion, though that interest was starting to get beaten down by her own budding arousal.

“Stars above,” Celestia murmured. “I can't believe you made something this strong.”

Twilight smiled. “Don't worry princess. Like you told me, a good pussy should always be hot, wet, and ready for her betters to use at their leisure.” She quipped.

Celestia tried to shoot her junior a glare, only for her eyes to roll into the back of her head and her body to shake violently. Twilight could tell the signs of an orgasm quite well at this point, and for a moment she wondered if the potion really did break the spell. Only for Celestia to suddenly stop moving just before the orgasm was about to actually hit her, leaving the alicorn as aroused as she was disappointed.

“You know, I think we should test things a little more thoroughly,” Twilight exclaimed, the mare scratching out a quick letter which she burnt with her magic.

The solar princesses’ hooves scrambled to grab the edge of the bed, but she found herself unable to find purchase on the soft satin sheets. Her back legs refused to follow her instructions, and after nearly a minute of fruitless scrabbling, she gave up and lay back down on the floor. Her mouth hung open, her tongue laying against the ground as her entire body continued to convulse only for that to stop as suddenly as it began a moment later.

“And now, we wait. Hopefully not for long though.” Twilight murmured half under her breath.

“Wait for what?” Celestia demanded before collapsing back to the ground and writhing in pleasure. “Oh gods, she’s taking me so deep.”

Twilight snickered to herself. “You’ll see.”

Glancing to the other mare’s back end Twilight found herself grinning from ear to ear at the sight. Namely, the way Luna was really going at it, evidently using some manner of dildo to really plow the Celestia toy she had been given. The white alicorn’s love tunnel twisted, convulsed, and dripped constantly, adding to the small pool that now formed near the pony’s back end.

A sudden flash revealed a piece of parchment that had been rolled up and stamped with a simple pink heart. “Ahh good, she got back to me before she had her fill of you,” Twilight murmured.

Pulling open the scroll, Twilight paroused its contents before giggling to herself and disintegrating the missive using a quick spell. “That mare. Sometimes I wonder how my brother isn't wheelchair-bound by now.” Twilight mused to herself.

Celestia was confused by the statement until all of a sudden her cock appeared between her legs, now absolutely soaked in another mare’s juices. The scent of Cadance’s arousal was potent and almost managed to mask the smell of Celestia’s veritable lake of girl cum. Evidently, the pink alicorn had been enjoying herself quite a bit, and after it reappeared, Celestia found herself able to breathe for the first time in what felt like forever.

“That was… unbelievable.” She murmured breathlessly.

“Well, I wouldn't say that quite yet. I did return it for a reason after all.” Twilight stated.

Celestia glanced at her former student with a look of trepidation. “Should I be afraid?” She asked, only to shudder.

“Perhaps. Perhaps not. Either way, I’m going to do something I’ve always wanted to do.” Twilight declared with a smile.

The white alicorn’s curiosity wasn't satiated by the response, and apparently, neither was Luna’s lust as Celestia began to quiver, her forelegs clutching uselessly at her pussy. Which continued to be played with by not only the ancient mare’s sister but also a new player, which she guessed was Cadance. Either way, Celestia didn't have long to consider that small change, as Twilight suddenly used a new spell, this one creating a familiar-looking portal directly before her.

A second later a familiar pillar of horsecock rose out of it and vanished from between Celestia’s legs. For a moment the alicorn wondered if her ex-student was going to use it in the same manner that Cadance had just done, but that changed when Twilight began to move behind her. Celestia watched in confusion, and then surprise as Twilight began to angle Celestia’s cock towards the alicorn’s own pussy.

“Wait, stop-” Celestia tried to shout, only for Twilight to merely grin and keep going despite her former mentor’s cries of protest.

The huge pillar of mare meat was then rammed unceremoniously inside of herself, leaving Celestia in a bizarre state of revulsion, and complete and utter euphoria. To feel her own cock enter her so deeply, and so suddenly inside of herself made her brain stop for a moment, the organ too perplexed to properly deal with the stimuli it was receiving. And then all at once she felt herself orgasm, or at least her body tried to anyway, as the spell stopped it at the last second.

Twilight snickered to herself. “Well Celestia, you did it, you successfully went and fucked yourself.”

“N-n-not f-f-funny.” Celestia stuttered between confused moans.

“Now now, let's not get too angry, this is in the name of science after all.” Twilight retorted. “In fact, why don't we take things a little further still. Let's see if orgasming a ton of times can break the spell. You already have one princess' permission after all.”

Celestia’s eyes became wider still, and she raised her hooves defensively. “N-no wait. Please, we can talk about this.”

“Like how we ‘talked’ about me getting released from the spell all those times?” Twilight replied, glaring intently at the alicorn who continued to twitch on the floor.

Celestia glared back for several seconds before finally sighing in defeat. “I suppose you’re right there. Fine, do with me as you will.” Celestia murmured weakly.

Twilight snorted and shook her head. “You know just how to rob me of my revenge boner. Oh well, I guess I’ll just use yours then.”

Grabbing hold of Celestia’s cock in her magic, Twilight pulled it out of the depths of the mare’s own pussy before plunging it right back inside. She had given the other pony no time to adapt, no time to gradually stretch, and she didn't feel like changing that now. It also seemed as though Luna had stopped playing with her Celestia toy, as the white alicorn wasn't moaning quite as much as she had been a minute ago.

Twilight smiled to herself, the lavender alicorn able to tell that her former mentor was doing everything in her power to resist the pleasure that assaulted her. It was a futile task, Twilight knew, but the fact that she was at least trying, spurned something in the princess of friendship. Beating her here would be a small, insignificant win, but it would feel nice to reduce the solar princess to a quivering pile of pleasure and cum.

Lighting her horn, Twilight put a little bit of extra magic into her telekinesis spell, pumping Celestia’s cock faster and faster into her own pussy. Twilight watched as Celestia’s cock repeatedly made her own stomach bulge ever so slightly, its tip visible through the white alicorn’s belly. It made Twilight grin wolfishly and get a little turned on by the sight of Celestia being forced to fuck herself so deep and so hard that anyone could see.

As this was happening, Celestia began to moan louder and louder, her legendary iron will faltering under the tidal wave of pleasure which pounded at the back of her mind. It was such a bizarre mix of the captivating sensations that it was almost disarming in a way, as Celestia didn't know how to gird herself against it. Thus as time passed she grew increasingly more animated, until she was actively pushing herself back against each one of Twilight’s thrusts.

Twilight grinned from ear to ear, silently relishing the tiny victory she had just achieved. A small part of her couldn't help but almost be disappointed that she was doing this to her former mentor, but the rest of her was in complete agreement. After all, Celestia may have coerced Twilight into agreeing to sex on numerous occasions at least mostly of her own free will but… Actually now that Twilight thought about it, she didn't exactly need any other justifications, that was more than enough.

With a gleeful smile, Twilight gripped Celestia’s cock even tighter and used her magic to violently fuck the white alicorn into the floor. Tongue falling out of her mouth, Celestia panted and moaned in whorish abandon, giving up all attempts to thrust back. It was simply too much, and the alicorn of the sun lay there as she was being violated, her massive, overfull balls pulsing needfully as they readied themselves for imminent release.

The two large white orbs were absolutely packed with seed, to the point that Twilight was fairly certain she could hear them slosh around with each thrust. The sound made the lavender mare grin even wider, already imagining just how much cum Celestia was seconds from pumping into herself. Still, the elder alicorn pretended to hold out for at least a little while longer, that was until the head of her cock pressed against the entrance to her womb.

An experience that should have been painful was made incredibly arousing by the odd angle hitting her just right. Celestia’s moan grew so loud that Twilight would have worried about the guards hearing them, provided that she cared about something like that in the first place. As it stood now though, Twilight didn't even think about something like that, as her entire being was focused completely on just fucking Celestia into a puddle of her own cum.

Something that didn't take long, as Celestia’s legs suddenly shot out in all directions, and her wings flapped uselessly at her side. “I’m cumming!” She cried, her voice rising a few octaves.

Her balls churned, and Twilight could visibly see the first shot of seed travel up the futa mare’s shaft. In response to this, Twilight rammed Celestia’s dick as deep and as hard as she could manage, ensuring every last inch of the mare’s throbbing mare cock was inside of herself. An action that made Celestia moan even louder, and writhe even harder, her titanic orgasm exploding inside of herself.

At that point Twilight was dripping a steady stream of arousal onto the floor, the debauched sight alone sending a bolt of electricity down her spine. Years of being treated like a toy by her own mentor suddenly didn't feel quite as bad as they did a moment ago. Plus if Twilight was being honest with herself, watching Celestia fill herself with her own cum also kind of turned the lavender mare on. It certainly wasn't something she wanted to try with herself, but it was something she planned on doing to Celestia every chance she got.

Cum splattered onto the ground, the white, hot seed all but erupting from Celestia’s overfull pussy. More and more of the stuff quickly followed the first spurt, Celestia’s overfull balls eager to empty themselves into anything, even if it was back into Celestia herself. The alicorn in question continued to writhe and moan, confused, aroused, and more than a little unnerved by the entire encounter.

On and on it went, each throb sending more and more of the piping hot cum directly into the mare’s own body. Until her belly began to bloat, and the tip of Celestia’s flared head vanished entirely, no longer visible due to the pudge Celestia now sported. Most cum slipped past the head of her cock, however, filling her love canal with stallion cream before splattering over the floor.

By the end of it all, there was a small ocean of the stuff between Celestia’s legs, which added to the lake of juices that had already been there. Her fur was stained, her pride tarnished, and as she lay on the floor, Celestia looked down, unable to meet her former student’s gaze. This was mostly in part to the fact that she was incredibly aroused, however, and Celestia didn't want anyone to know just how much this had turned her on.

Not like she needed to bother though, as Twilight saw right through her attempts to save face and preserve her pride.

“You know, one of the spells I had cooked up for you made you quite virile and I’m not sure I remember which one I ended up casting on you,” Twilight remarked with an air of exaggerated confusion.

“Y-you didn't,” Celestia murmured, gazing up at Twilight with a fearful expression.

“Oh yes, you may have just knocked yourself up,” Twilight claimed. “Or maybe not and I’m just teasing you? I guess only time will tell.”

Celestia gaped. “Thats-”

“Impossible, unlikely, something you would do?” Twilight finished, the mare leaning down and smirking at the prone alicorn.

Celestia bit back the urge to reply with how she truly felt. “Strange.” She muttered bitterly.

“I guess so. But let’s up the ante even more shall we?” Twilight offered.

Celestia grimaced. “Can we not?”

“Aww come on, you don't even know what I had in mind.” Twilight pouted.

Celestia frowned and she held a hoof against her bloated belly while slowly crawling into her bed. “Fine, I’ll bite. What did you have in mind?” She asked.

“Well, I was thinking that we really need to make sure we test the furthest limits of this little forced heat potion. After all, there is a chance, however small, that it could actually break the denial enchantment.” Twilight began, striding up to the bed and looking down on Celestia. “Which is why you will be allowed to cum as much as you want until Luna or Cadance say otherwise.”

“Really now? What's the catch?” Celestia asked while reaching between her legs.

Twilight swatted away the mare’s hoof. “For one, you are not allowed to remove your cock from inside of yourself.”

Celestia frowned, but reluctantly moved her hoof away, while at the same time keeping one limb placed against the bulge in her midsection. “And the second catch? Or are there more than just two?” Celestia asked, her voice tinged with a bit of venom, but also a hint of curiosity.

“The other half of our little experiment will be the activation of every single Celestia toy in Equestria.” Twilight proclaimed. “All thirty thousand or so.”

The color drained from Celestia’s face and she looked up at Twilight with fear in her eyes. “Please no.”

“I’m sorry, but toys don't get to make decisions,” Twilight replied with mock pity.

Before Celestia could do anything Twilight had cast her first spell, sealing Celestia’s cock firmly inside of herself. Next, the lavender mare cast a second spell, this one opening up Celestia to all the many, many toys which were tied to her cunt. In an instant, Celestia was lost in an endless sea of forced pleasure, her body ragdolling as she fell back to the bed, magic sparking uselessly.

Her resistance was gone, and any attempt at articulating a response was as well. Her entire body trembled, and spasmed violently, her balls already beginning to produce and ready more sperm to be shot into the alicorn’s already full womb. Twilight knew that alicorns were as durable as they were stretchy though, so she had no concerns that Celestia may accidentally injure herself in the process.

That was put to the test a second later though, when Celestia came again, pouring another heaping helping of cum inside of herself. The orgasm was so sudden, and so surprising that Twilight was actually taken aback by the entire event. She reacted quickly though, smirking as she watched Celestia pump herself full of more hot alicorn spunk.

It was a sight she was growing to enjoy more and more every time she saw it.

“Well, it seems like you are too occupied to describe what you’re feeling. Though I wonder if Luna would enjoy seeing you like this.” Twilight mused.

Celestia’s garbled moans grew more frantic, and for a moment it almost seemed like she was going to be able to utter a response of some kind. Only for another orgasm to reduce her to a quivering mess, her cock pulsing so hard that she temporarily forgot how to speak. Prompting Twilight to snicker as she watched her former mentor fill herself even more, Celestia’s stomach visibly growing with each spurt of cum that was shot inside of her.

“I’m sure she would rather enjoy this. Cadance might as well now that I think about it.” Twilight tapped her chin. “We should make an evening of it sometime soon and invite all the girls down in order to enjoy your body fully.”

Celestia gurgled, spit dribbling down her chin as the mare’s eyes rolled into the back of her head.

“I bet you would like that though, wouldn't you? Being passed around like the cheap, worthless whore that you are.” Twilight spat.

The white alicorn couldn't utter a response, though the flicker of recognition in her eye told Twilight that she had at least heard her.

Smirking to herself, Twilight rose back to her full height and sniffed the air. “I’ll have to send in the maids at some point in the evening. Though I guess I’ll leave that for later so you can get used to what you’ll be smelling like from now on.”

Celestia’s wings flapped, and her twitching hoof knocked a pillow from her bed, body arching as she pumped yet another load into herself. Cum shot out of her overfull love canal, adding to a growing pool which had begun to form into the bed. The stained sheets would have normally bothered Twilight, but the lavender mare knew that Celestia had spared no expense with her linens.

“What, nothing to say?” Twilight giggled to herself and shook her head. “I suppose this is goodbye for now. Make sure to pleasure Luna well and she may just stop the spell.”

Twilight trotted to the door and stopped just as her hoof reached the knob. “Though if I were her, I’d leave you for a few hours or so.”

Celestia twitched and reached out with a shaky hoof.

The lavender mare shrugged. “Have fun.”
