Chapters Holding Fast and Letting Go
I want to stick my tongue in her fat ass.
Dr. Mary Parvotti couldn’t help the intrusive thought. She considered herself a bit of a connoisseur, having had many opportunities over her thirty-one years to sample rear-ends of many different shapes and sizes. But the fantastically plump butt she was looking at now was a work of art, in a class of its own. It was like putting finger paintings up against the oeuvre of Monet.
It wasn’t as if she herself was any slouch in that department, either. She’d often heard her old friends from college call her names like “thicc” and “Pixar mom” when they thought she couldn’t hear, and she always noticed the looks she got when she squeezed herself into the little black dress she was currently rocking, trying to make an impression at formal functions like this one. Her short brown hair and smallish breasts didn’t always do her many favors, but she could always depend on her tight round posterior to draw attention.
In any case, nobody was looking that closely at her tonight, and for good reason. A historic personage was sitting there at the long dining room table alongside a handful of other dignitaries, representing an event without precedent in the long arc of humanity’s existence. As such, it was wholly fitting that the subject of Mary’s fascination was something very different from a human. Different, but not entirely so.
A forkful of tender chicken hovered in the air supported by nothing, floating over to a pale white muzzle which opened to take a delicate bite. Big bright eyes shone with genuine pleasure, and the smile beneath lit up the darkened room. “Wonderful. This dish alone was worth the trip.”
Any way you looked at it, Princess Celestia, otherwise known as the Sun Princess, was a horse. She was at least half again the size of the largest Earth stallions and colored an impossibly brilliant shade of white with prismatic highlights in her coat and eternally flowing mane, but the general form was unmistakable. It had been the first thing the media commented on when she sauntered out of the strange portal, alone, in the middle of Times Square a month prior.
Mary’s gaze went to that heavy rump, perched upon the lucky cushion on the floor. Big, round, and emblazoned with the now-famous sun sigil—or cutie mark , as it was apparently called—her eyes had been drawn to it again and again throughout the dinner. Of course, they couldn’t find a chair that could hold her size and weight, but Celestia had graciously suggested a seat pad to rest her haunches upon, waving aside the protests of nervous government officials about a visitor from another world sitting on the floor like an animal. She was gracious about a lot of things, actually…and hard as stone about others. Mary was sure she’d been in these ambassadorial situations many times before.
One of the uniformed generals to her left chewed thoughtfully on his own rare steak as he blatantly stared at the visitor. “Kind of shocking that you can even eat our food, much less enjoy it. Certainly makes things easier for everyone, but I wouldn’t have bet on it for first contact.”
Mary took a sip of water. “The Princess has been very forthcoming with, ah, access to her person for research purposes. The lab couldn’t ask for a better subject, and we were able to figure out her nutritional needs quickly with her cooperation.” She paused, still marveling at the unreality of the whole situation. Thirty days, and yet the time before Sun Princess Celestia’s arrival in their dimension still felt like another age. “There aren’t many xenobiologists out there, and none of us go into the field expecting much direct application of our knowledge. I consider myself fantastically lucky.”
The woman across from her in the cream-colored formal dress finished her glass of wine to the dregs, then motioned for another, brushing long red curls away from her freckled face as she waved for the waiter’s attention. “I wouldn’t call that luck, really. You worked hard your whole life, and when the time came, they picked you because you’re the best. Not like me, who was just in the right place at the right time.”
Her light Irish brogue was already somewhat slurred, and she took a big swallow of her fresh glass. “Ridiculous, isn’t it? The interview of my career and a Pulitzer in the bag, all because I happened to be doing a damned traffic story when she just traipses in front of the camera out of nowhere, casual as you please. What else what I supposed to do?” She blinked, as if suddenly aware of the state of herself. “Pardon my language, Princess.”
Celestia’s voice was a viola playing the sweetest melody. “Not at all, Ms. Taggart…or, may I call you Erin? I’ve always believed that luck is its own type of magic, possibly even more powerful than my own. It led me here, to both of you, and as a result things have gone much more smoothly than they might have otherwise. Don’t ever discount luck.” The pure white spiral jutting out of her forehead glowed, and her own wine glass lifted into the air.
Mary had spent a good amount of time with Princess Celestia in the past few weeks, but she still needed the occasional reminder that the visitor wasn’t really a horse. She called herself an alicorn , and if you were going to send out an ambassador from a magical realm, using a unicorn crossed with a pegasus seemed like the way to make a strong first impression. Of course, the undersized white wings at her back had to be vestigial; there was no way they could ever carry her considerable weight. Not with their current knowledge of aerodynamics.
With magic, however, everything humanity thought it knew was turned upside down. Celestia had demonstrated many outrageous abilities to the world’s leaders, but even the simple telekinetic manipulations of cutlery fascinated the biologist.
She hadn’t been the only one. Some nations had joined together to push for more access to Celestia’s abilities, and now an impeccably-tailored representative of that bloc raised his steak knife from down-table. “I do hope the relationship between our worlds can grow enough for you to trust us with this ‘magic,’ Princess. Give us a chance to prove ourselves worthy of your secrets. As I’ve said before, I believe we have much to teach each other. Wouldn’t you agree with that, at least in theory?”
Celestia put a gilded hoof to her chin as if in thought, then she looked at Mary. “What do you think, Dr. Parvotti? Could you, yourself, be trusted with magic?”
It felt like a test, and she hesitated before deciding that truth was the simplest approach. “Part of me would love that, Princess, I’ll admit. Something like telekinesis would be like a dream, but…” Mary frowned. “I can’t guarantee that I wouldn’t use it to murder someone someday, on accident or otherwise. I know that about myself.”
She sat back in her seat, fully aware of the Princess’ serene gaze. “But more than that, I think magic should be magical , if that makes sense. When we understand how something works, it becomes technology. It loses its wonder, its ability to inspire. I guess…look, I know it sounds crazy for a scientist to say this, but I don’t need to learn all the ins and outs of spellcraft right now. It would be like waking from a dream.”
Princess Celestia stared at Mary for a few more seconds with an unfathomable expression. She then turned and called for a waiter, who only came up to shoulder height next to the reclining visitor. “A bottle of your cheapest wine, please. No need for anything fancy.”
When it was brought, she levitated the bottle out of the presenting basket as she looked around the table. “As a gesture of sincerity, I shall teach this spell to whoever wishes to learn it. It’s only minor hearth magic, so it shouldn’t be too…disruptive, but you should find it useful. Normally, alicorn magic can only be used by an alicorn, but a new world means new rules, and some of you have potential. Now, watch closely.”
The glow around her horn began to slowly shift through rainbow hues. “This isn’t the flashiest spell, but I’m sure you’ll all appreciate the results.” Mary soon saw the air around the bottle glowing in synch with Celestia’s horn, and she found herself holding her breath in suspense.
After half a minute, the glow faded. Magically popping the cork, Celestia gave the initial pour to the journalist sitting across from her. “As the first human to communicate with a being from another dimension,” the Princess said with a mischievous grin, “you should also be the first to try magically fermented wine. I get the impression that you have an appreciation for such things.”
Erin gasped at the unexpected honor. “I…I don’t know what to say…”
“Don’t say anything,” Mary said with a laugh. “Just take the drink offered in goodwill.” She harbored no jealousy toward the reporter. There would be plenty of firsts to come in the future.
With a bright smile, Erin took a sip. Her eyes instantly widened in wonder. “This is unbelievable. It’s like ambrosia!”
“You may call it that, if you like,” Celestia said as she watched Erin finish her glass with that ageless smile. “This spell can turn even the meanest wine into the finest vintage. It also works on liquor. I’d actually be curious to see the effects on the different spirits of this world, so please, experiment as you like.” Noises of amazement went up and down the long table as the Princess called for more wine to convert and glasses for the others.
While her attention was elsewhere, Mary once again found herself closely examining the Princess’s backside. She didn’t know what the visitor ate in her own world, but it was clear where the calories went. Mary tried to tell herself it was the biologist in her that motivated her urge to reach out and touch the white flesh, and she tried to imagine what she would feel. Would her ass be muscular and unyielding, like the flanks of a workhorse, or would her fingers sink into pleasing softness?
And what was between those glorious cheeks? Mary leaned back a little as she tilted her head, trying to catch a glimpse of what she truly sought…
“Would you like a taste?”
Mary’s head jerked upwards. A floating wine glass full of ambrosia hung there before her, and behind that, an equine face full of amusement.
“I…yes. Thank you.” Mary took the proffered glass with a shaky hand, cursing her sudden timidity. She had no illusions about Celestia’s ability to see right through her, but she was glad the visitor seemed to have a sense of humor. The last thing she needed was to cause an inter-dimensional incident.
Celestia nodded. “I hope it’s to your liking, little pony.” She immediately gasped, then let out an embarrassed chuckle. “Forgive the offense, Dr. Parvotti. I don’t mean to demean you. Some habits are very hard to break.”
Mary shook her head vigorously. “No offense taken, Princess. In fact, go ahead and call me that if it makes you more comfortable.” It seemed like some sort of term of endearment, and the biologist found herself flattered that Celestia had grown comfortable enough with her to use the phrase. In companionable silence, they both watched the dignitaries enjoy their ambrosia with delighted exclamations in various languages.
“I adore this part of the process,” Celestia said at a volume that only Mary could hear. “New relationships, new opportunities. It doesn’t always go this well.” She telekinetically swirled her own glass without taking a drink. “These moments are always so pregnant with potential, but there’s something sweet about the waiting before reaching out to grasp what we seek. I almost don’t want to empty my own glass, so I can linger in this emotion. Isn’t that strange?”
“Not at all,” Mary replied, tasting her own ambrosia. It truly was outstanding, and so strong! “There’s a word for that in one of our tongues. ‘Vorfreude’ is German for ‘the feeling of anticipation before claiming a thing long desired.’ Roughly. I’m afraid I don’t speak the language.”
“Hmm.” Celestia’s eyes were on Erin, the Irish-born journalist with the magical luck, currently finishing her second glass with relish. The Princess’ expression was neutral, but Mary sensed something beneath the placid facade. Not for the first time, she wondered what the real Princess of the Sun was like, away from the generals and politicos and news cameras. What would it take to get close enough to find out?
Abruptly, Celestia rapped a gold-sheathed hoof against the table, calling for silence as she floated her glass to the center of the dining room. “A toast, my new friends. To vorfreude,” she said, glancing over at Mary. “May we all learn to live in the moment before grasping the future.”
Cries of agreement went up around her. However, before Celestia could take a drink, Mary raised her own delicate crystal aloft.
“One more, if you don’t mind.” She’d meant to address the room, but she only had eyes for Celestia as she spoke. “To magic. May we never lose our wonder.”
The Sun Princess met Mary’s gaze as she clinked the biologist’s glass. “To magic, little pony.” And she drained her ambrosia in a single gulp.
Mary opened her eyes into darkness. She lifted her head as she blearily looked around, hearing a soft electronic tinkling sound somewhere to her right, and another soon after.
Familiar forms began to take shape as she remembered where she was. To her left, ocean waves broke against a moonlit beach just outside her bedroom window.
Secret island bases were par for the course for any decent-sized government, and arrangements had quickly been made to house Princess Celestia in comfort and seclusion. More of a hotel than the military installation it actually was, the suite she’d awoken in was as plush as any Hilton. There would be other, better facilities later, but the biologist had found their lodgings more than adequate for such short notice.
Mary sat up on the bed and took stock of herself, seeing that she hadn’t even changed out of her dinner outfit. She put a hand to her forehead, shocked at the fact that she couldn’t remember how she’d made it back to her room. A drunken blackout was a new experience for the biologist.
“Fuck,” she whispered. “God, that wine must have put me on my ass. Tell me I didn’t do anything too unprofessional.” Mary grabbed the provided burner phone from the bedside table, and groaned as she saw 1:20 a.m. on the screen. She was preparing to strip and burrow under the covers until the morning before realizing she hadn’t checked her messages.
She entered her passcode with an uneasy feeling, seeing two unread texts. They had both been sent within the past few minutes, as if timed to her awakening.
The first read, “Come to my room.”
The second read, “Alone.”
The name of the sender was simply, “C.”
Mary stumbled off the bed and into her flats, cursing to herself as she wondered what idiotic actions she now had to answer for. She thought of changing clothes, but something told her that haste was more important than what she was wearing. The bright fluorescent lights of the facility hallway almost blinded her as she left her room, and she headed for the elevator to the top suite as quickly as she could without actually breaking into a run.
Her apprehension only increased riding the lift to Princess Celestia’s floor, and she slowed her pace as she walked down the last hallway toward the interior quarters. Mary didn’t know exactly what she was afraid of, but her stomach was doing somersaults, and the feeling intensified as she went further. She worked through scenario after scenario in her head, trying to figure out what the Princess could want with her at such a late hour, but nothing reasonable came to mind before she finally reached her destination.
She sighed. There was nothing for it, she knew, except to face whatever was coming with as much dignity as she could muster. Steeling herself, she raised her fist to knock, but as she did so she saw the door move slightly.
It was unlocked and unlatched. Beyond, she heard movement and soft voices.
Mary hesitated. Protocol instructed her to not walk in unannounced, but she had been invited. That, and an open door in a place like this was suspicious. If there was a problem, or even some kind of danger, then…
“Princess?” Mary called as she pushed the door open and stepped inside.
The first thing she noticed was the smell. It was more accurate to call it a musk, thick and heavy, a locker-room aroma that assaulted her nose. It was the stink of exertion and bodily fluids, familiar on its surface, but also alien and intriguing. She caught herself taking deep whiffs of the air, wondering at her own reactions.
In the darkness of the suite’s luxurious living room, Mary could just make out a hulking form. It was round, and subtly moving, and from it she could hear strange, sticky noises. One of the voices she’d heard earlier was a little louder now, sounding high-pitched and breathy.
Mary took another step into the entryway. The door behind her closed with a thunk, and she jumped at the sudden sound, but the form in the center of the room did not react. Whatever it was only continued its steady, rhythmic motions.
As her eyes adjusted to the low light, the shadowy outline resolved into a form that made her heart beat faster. Her breath began to come in gasps. She wondered if she were still asleep in her bed, experiencing a dream brought on by too much wine and stimulation, but as the moon came from behind the clouds to illuminate the room through the glass patio door, Mary knew that what she was seeing was as real as the night sky itself.
Celestia’s enormous, white, sun-kissed ass was almost big enough to encompass Mary’s outstretched arms. The alicorn was in a crouch, legs spread for better purchase as the muscles in her wide buttocks strained and roiled. Mary could see the dark anal ring she sought during the dinner clearly now, pulsing and flexing with each desperate shove. She felt herself began to drool, but made no motion to wipe her lips.
There was a loud, feral grunt as Celestia gave a sharp thrust without warning, pushing forward another inch, and the voice underneath her moaned. Her fleshy ass clapped and jiggled as she forced herself inward, and Mary could hear a vulgar sucking sound, like a fist sinking into deep mud.
Another grunt, and Celestia raised her gigantic ass and hips, preparing for another hard pump. Underneath that delectable asshole were two large testicles, each as big as basketballs, swinging lazily between the Princess’ massive thighs. They fairly vibrated with vitality, and Mary could almost hear their contents roiling, preparing for release.
Another shaft of moonlight, and then, there it was.
Princess Celestia’s monstrous cock was a fleshy, pink and black mottled log, at least twelve inches in diameter and pulsing needfully. Wrapped around it was the shaven cunt of a woman on all fours, stretched wider than any human being had ever been stretched while still breathing. Her lower body was raised off the ground, impaled on the nightmarish organ as the Princess drew back further, and Mary could see the outline of the rest of Celestia’s cock deep in the woman’s stomach. Even the wide flare was visible, just underneath what should have been the human’s rib cage.
Stringy red curls hung below the woman’s…no, Erin’s flushed face, dripping with perspiration.
It was impossible. Erin should have been destroyed by such an appendage, but her organs were re-arranging themselves to take the monstrous thing. And far from feeling pain, the moans and gasps Mary heard made it sound like she was experiencing a kind of pleasure never before felt. Not by humankind, in any case.
This was magic. Harder and more raw, but just as real as any of the other wondrous things she’d seen.
And Princess Celestia wanted her to see it.
With another grunt, the alicorn jammed her cock further into the wet, clasping hole underneath. Erin screamed, but Celestia did not stop. Her giant ass strained and flexed with effort, and Mary watched as the outline of that horsecock slowly traveled a few more agonizing inches into the journalist’s torso.
Erin began to speak in tongues as she came, and her green eyes rolled into the back of her head while cream splattered onto the carpeted floor under their conjoined bodies. The contractions sent the Princess over the edge, causing Celestia’s balls to quiver and pulse. With a loud, throaty moan, she achieved her release.
The tiny belly underneath had no chance to contain even a small part of the Princess’s load, and the splatter of come was like a garden hose in the quiet suite, covering their lower bodies and soaking their legs. Celestia’s cock pulsed again and again, forcing out its contents, and her wide ass quivered and clapped, thrusting in quick, intense motions as she took her pleasure. Her orgasm took a good minute, and when it was done, the carpet underneath was saturated with creamy white fluid.
Mary barely felt her knees hit the tile floor of the entryway. Her hand went to her black-pantied crotch, and her fingers slipped deep into her own drenched cunt as she watched the display, overwhelmed by the sights and sounds. She thought about running away, about going back to her room to forget about everything she’d seen up to now, but the urge was fleeting. Something else was in control now, something more base and primal.
And it wanted to see more.
After a few tense moments, Celestia stirred. Her cock was still sensitive, and she hissed as she began to draw herself out of the prime pussy she was buried in. The poor reporter whined as the oversized tool dragged across all the sensitive parts of her invaded channel, and excess semen dripped and squicked from her hole with every inch the Princess extracted. Five…ten…twenty…at least three feet of sticky, come-covered horsecock revealed itself, hot and steaming in the musty air. The wide flare required a rough tug from Celestia to lodge it free from that tightness, and at last Erin collapsed face-down with her ass raised high, shuddering and moaning in delicious agony.
Mary could have slipped both arms into the dark hole that was the woman’s destroyed cunt, immersing her hands into the endless wash of thick white seed flowing from those reddened insides. The sight was both horrifying and fascinating at once. If magic could allow a human being to take Princess cock, then it could fix that wide-stretched pussy, but this was not just a physical distortion. There was no way she could ever be the same again…even if she wanted to.
Celestia let out a languorous sigh, then she turned her head, meeting Mary’s gaze across the darkened suite. Her face was that of a nun being fucked on an altar, holy yet obscene. Seeing the action of Mary’s fingers, her lips turned up in a soft, knowing smile, and a long pink tongue wet her chops.
She rose to her full standing height, moving to face Mary while taking deep breaths, enjoying the extra nuances that the newcomer’s excited aromas brought to the room’s bouquet. She held Mary’s eyes fast as she prowled to the entryway, stalking more like a panther on the hunt than the herbivorous horse she resembled.
Her sticky cock had not softened in the slightest after her orgasm, and dollops of pre drooled out of the wide open tip. The fat fucker slapped against the alicorn’s soft white underbelly with each throb of her pulse, and the swinging balls behind rumbled, already generating a new load. Mary dug three, then four fingers deeper into her own overheated cunt as she watched the Princess approach.
Celestia stopped at the tile entrance, sitting down on her haunches not a foot from where Mary was desperately churning her fuckhole. The visitor displayed her ridiculously thick, three foot long royal cock proudly, and it looked even bigger and more intimidating up close, more fearsome than any weapon. Her muzzle was open slightly, and she breathed in a steady, measured rhythm as she looked down at her prey with lidded eyes.
Seeing the messy puddle underneath Mary’s knees, Celestia began to thrust her own hips, slowly fucking the air as she smelled that spicy essence. She grunted, and a jet of cloudy come spurted from her cock head, streaking Mary’s face and soaking the front of her black dress with a messy offering that would have been twice a human’s full load.
Mary touched her cheek with her free hand, rolling the tacky substance around on her fingers in wonder. The concentrated smell of pure sex made her eyes flutter, and her plunging fingers worked faster and faster. The biologist in her immediately knew what Celestia was doing.
She was marking her bitch.
Without warning, Mary’s own hips began to thrust, fucking up at nothing as streams of come began to squirt from her red-lipped, wide-open cunt. Over and over again, she came, clenching her core almost painfully with each contraction, and the streamers of fragrant liquid covered Princess Celestia’s chest and thick cock in loving tribute. It was the strongest orgasm that she had ever experienced in her thirty-one years of life, and it left her trembling with violent aftershocks.
Celestia watched the whole display without changing her expression, only flexing and thrusting her own haunches in sympathy. She waited until Mary was finally still, though the human couldn’t keep her fingers out of her creamy twat while she fought to get her breathing under control.
“Did that take the edge off?”
Mary was as shocked as if she’d just heard a dog speak. Clearly, Celestia was still in control of herself, though her achingly hard fucktool and panting mouth implied that it was taking some effort to stay that way. Not knowing quite how else to respond, Mary gave a slight nod.
“Good.”
Celestia closed her eyes as her thrusting slowed, then stopped. She opened her eyes again, and Mary saw that the barely restrained hunger in her expression had lessened, but not entirely disappeared. The mask of calm that she wore was still there, yet cracks were showing.
“Vorfreude.” The Sun Princess took a deep breath, letting the sound of the word linger. “I think…I think I have a better appreciation of that term now. I…”
Celestia’s breathing hitched, and another strong gout of sticky come exploded from her loins, landing on Mary’s upper thigh. It felt like fire, and she resisted the urge to touch the mess on her skin.
“I’m going to fuck you, little pony.”
The Princess said the words with a deep, guttural intensity that went all the way to Mary’s womb. “I’m going to squeeze my fat Princess cock into your…tight little fuckhole and stretch you so wide, you’ll be ruined for anyone else. I won’t stop until I bury myself balls deep, then I’m going to destroy your little human cunny.”
She let out another spurt of cream. “And…and after that, I’m going to fill you with so much spunk, it’ll be leaking out of your sloppy gash for the rest of your life. I know that’s what you want, isn’t it? Isn’t it, dirty horsefucker?”
Hearing the Sun Princess refer to herself as a base animal sent another jolt of arousal into Mary’s brain. It was as if she’d seen the biologist’s deepest, most private fantasies. She tried to respond, but her body wouldn’t follow her directions. “I…but…but I’m not a…”
“Yes, you are. I’m going to do all of those things to you, Dr. Parvotti…but not yet.” Celestia’s mask was still on, a little tighter than before, but only just. “First, you need to better understand your place. You need to give yourself to me.”
Holding Fast and Letting Go
Princess Celestia bent down, taking one of Mary’s dress straps in her teeth and dragging her forward through the mess she’d made on the tile floor by her scruff.
Mary felt a brief spasm of fear. Celestia’s teeth were large, white and likely razor-sharp, and Mary was sure that the alicorn would have no trouble biting her head clean off if she’d been so inclined.
Of course, Celestia could have also levitated her easily, which meant that this was a clear display of strength. Of dominance.
Celestia tugged the unresisting Mary across the threshold of the entryway. Then, with an impatient jerk of her head, she tossed the human the rest of the way into the room, causing her to tumble and slide across the soggy carpet. With a squish, she came to a stop near Erin’s insensate form, and her face ended up almost directly underneath the reporter’s upturned ass.
Mary tried to look about in a panic, but the yawning mess of Erin’s cunt encompassed her entire field of vision. The dripping entrance had shrunk some—Celestia’s magical protection was still working to keep the woman in a vaguely human shape, it seemed—but it still looked like she’d given birth to a bowling ball. A viscous drizzle of come oozed out of her depths, landing on the biologist’s forehead and down to the bridge of her nose, still hot, still brimming with the sun’s energy.
Princess Celestia took a seat on the floor against a wall, across from the two. She lay on her back with her massive thighs spread indolently, and she began to stroke her thick meat with soft, unhurried strokes of her hoof. Her wide, white ass gently bounced against the ground with steady movements as she regarded her new playmate.
“Now. Eat what I’ve given you. I made it all for you, little pony. You’ve been trying to fight it, but there’s no reason to go against your own instincts, is there? All you need to do is what comes naturally.” A steady flow of slippery come leaked from her tip of her giant shaft, and she groaned as she worked the cream along the length, increasing her own pleasure as she stared Mary down. “Go ahead, doctor . Lick up all my come, right out of her blown-out cunt. Do it.”
Mary slowly sat up, intending to say or do something to try to make sense of the surreal situation, but as she did so, a drop of Celestia’s essence dripped across her full lips and into her open mouth.
It tasted like vanilla. And strawberries. And daydreams, and love, and prostitution, and bondage. It tasted like the cock-saturated breath of a bride fucked an hour before the wedding, or the milky nipples of the MILF down the street taking her son’s college friends three at a time.
It was pure, lotus-eating hedonism, raw and unapologetic. And she couldn't get enough.
Mary slid her hands over her face, capturing as much of the sticky cream as she could before shoveling the mess into her mouth, making noises of rapture. She looked over at Erin’s cunt, awash with more flowing come, and she put her hands underneath the slimy gash like a traveller dipping into a mountain stream. She collected more of the delicious juices before bringing her palms to her lips, swallowing with messy abandon. Then she did it again. And again.
A sheen of sticky wetness covered Mary’s face and chest. Somewhere in her frenzy, her little black dress had bunched down to her waist, revealing her B-cup tits and nipples, and now clumps of Celestia’s musky jizz stained her bare skin, but the enraptured human was past caring. When she finally extracted all the come from Erin’s messy pussy, she put her tongue to the carpet, slurping as much as she could out of the honey-colored fibers.
Princess Celestia’s hoof moved faster against her thrumming cock. “Oh, you are so fucked up, aren’t you? I’ve never seen anyone respond with such need. Drink it all down, little pony, that’s it. Fill your belly with my love.”
Eventually, Mary could no longer taste Celestia on any surface around her. She leaned back and closed her eyes, smacking her lips as she reveled in the delectable flavor still coating her mouth.
Upon opening her eyes and seeing Princess Celestia getting herself off to her actions, Mary groaned as understanding hit her. Celestia had wanted her to see what an alicorn on the edge of control looked like, and in return, she’d demanded the same from Mary. Was there something in that royal semen that was doing this to her? She had to keep a better hold on herself.
“What did…what did you do to…”
Celestia’s hoof started to stroke a little faster, and her wide hips began to jerk. “Let me tell you a secret. It’s not my come driving you crazy. If you put it under a microscope, you’d find we’re not that different.”
Mary wished she remembered what had happened at the dinner after the toast. There must have been something that had drawn the Sun Princess’ attention to her. God, that wine was…
“The wine,” Mary slurred, trying to focus on the Princess jerking her meat in front of her.
“Ordinary table red,” Princess Celestia said as she began to pant. “A little more…ah, fuck…alcohol content from the spell, that’s all. But make no mistake. You’re still addicted.”
Mary was about to deny the Princess’ words before she looked down at herself. Her black panties were hanging off her ankle, and she was plunging four fingers inside her own needy, gooey cunt with a slow cadence, making the stickiest, sexiest sounds imaginable. Gradually, watching her hand as if it belonged to someone else, she made a fist before plunging in to the wrist, and she moaned as her clasping walls squeezed and contracted.
The Princess let out a throaty laugh. “Yes, you’re addicted. Not to my come or my wine, but to me . You need my magic to make you feel whole. You saw what I did to her , and you want in, don’t you?”
Celestia matched her own strokes to Mary’s thrusting pace. “I can give you what you want. I can let you experience that magic, but doctor …you’re not Erin. You can take so much more, and give so much more. You can match even my hunger. I can tell. Because you see, I’m addicted too.”
Her heavy cock leaned back toward her body, unable to stand completely upright under its own weight. The constantly leaking tip was pointed directly at Celestia’s own drooling maw, and she gasped, as if seeing it for the first time. She seemed hypnotized by the oversized organ.
“I’ve…lived a long time, Mary. I’ve beheld so many wonders, and fought through so many hardships. The only thing I’ve been able to count on across all those years is my own body’s lust. I…I get lost in it. I’m a slave to my body, doctor. And I can’t…get…enough.”
Celestia’s thrusting stopped, but not her movement. Her hips hunched steadily upward, bringing the spongy head of her tool closer and closer to her mouth. Her long tongue snaked out almost shyly, touching the cloudy precome dripping from the side of the flare, and she whined at the taste.
“I’m a slave to the thick spunk churning in my balls,” she whispered. “To my sweat. To my smell. To my glorious ass, and the needy hole within. To…to my…”
With a loud groan, Princess Celestia bent almost double, sliding her fat cock into her own wide-open jaws. She sputtered and choked as she shoved, roughly pushing past the entrance of her gullet and sinking her royal fuckstick deep into her slender neck. Mary looked on in wonder as Celestia swallowed her own meat, watching the unmistakable shape deform the alicorn’s soft-furred throat.
Mary was not inexperienced when it came to sex. She’d had more partners than most, and she’d found herself in many situations that others might call kinky, or even bizarre. But watching Sun Princess Celestia, visitor from another dimension and magical representative of an entire species, deep-throat her own two-foot-long cock like she needed it to live…it made her feel like a trembling virgin.
This was, by far, the filthiest sight she’d ever seen.
It was the look of utter abandon. The way Celestia gratified herself without shame or inhibition, as if she were the only being in the world, was something she’d never seen in another human. Mary plunged her fist into her own messy cunt over and over again, unconsciously reaching for that lack of restraint.
Celestia choked and glucked as she fucked her own throat, swallowing cupfuls of pre while her stomach rumbled for the main course. Mary thought she might bruise her own nose with the power she was using, but if there was any discomfort, the alicorn gave no sign. Her eyes were unfocused, seeing nothing but the enormous balls slamming against her face over and over again.
With her hand still buried deep in her pussy, Mary began to awkwardly crawl forward on her hands and knees. In the frantic rolling of Celestia’s massive rump, raised up high with her contortions, Mary saw what she had been seeking all along: that mouth-watering asshole, dark and flexing with each hard jab. Despite the Princess’s size, it looked tight and inviting, and as she crawled closer to those wondrously thick cheeks, she decided she would not deny herself the satisfaction she sought.
When Mary touched that ass, Celestia slowed her face-fucking, as if waiting to see what would happen. The alicorn’s legs were opened wide, with her rear hooves around her head, leaving her round white asscheeks spread and her anal ring at the perfect height for the kneeling human.
With a moan of contentment, Mary pushed her face into that winking taint, licking and biting the black rubbery ring before tasting deep inside. As she’d expected, Celestia’s asshole was incredibly tight, clasping on her searching tongue, and the taste…she didn’t know what she’d expected, but it was like licking pure arousal. She shoved her face deeper into that royal ass, trying to make the most of the fulfillment of her fantasy and taking everything the Princess had to give.
Celestia’s hunching sped up, growing more urgent. Her clenching asshole was pulsing wildly against Mary’s face, and she thrust her cock as far as she could down her throat to maximize the surface area of her tight esophagus around the monstrous weapon. Hilting herself to the base, she licked her oversized balls gently, trying to coax out the creamy reward within.
All at once, Celestia’s anus began to flutter and twitch, and Mary thrilled as she awaited what was about to happen. Her tongue was forced out by the strong convulsions, but she kept her mouth around the outside, biting and licking the flexing hole as the Princess’ balls contracted.
With an audible spurting sound, Celestia blew her load directly into her own stomach. The cock sunk deep within her maw throbbed and pulsed with each jet of heated come, and her midsection noticeably bloated as she took in her meal. Even the Sun Princess could not hold so much at once, and after the first few surges, the remainder spewed from around her mouth, running down her regal face and splashing her chest. She didn’t even close her eyes against the flood.
Mary was not spared from the deluge, taking gush after gush of the Princess’s load on her own head. She raised her face, taking the libation like a sacrement, moving her head back and forth to receive the shower while scrambling to shove as much come into her ravenous mouth as possible. The smell of Celestia’s massive load combined with the aroma and taste of her delicious asshole made Mary’s cunt clench tightly against an invisible cock, and she came hard, spurting and gushing her silky cream underneath that glorious ass. She had never had an orgasm without touching herself, but then, she’d never squirted before, either. The night was full of firsts.
Celestia slowly drew her fat cock from her gullet, still moaning as she enjoyed the sensations of her throat around her length. With a wet pop, she freed her flare from her mouth.
The Princess blinked, coming back to herself after her climax. Gasping with exertion, she grinned at the tip of the organ that had given her so much pleasure, planting a chaste kiss on the wide slit and receiving one last burst of come against her right eye as a reward for her devotion.
Celestia lowered her ass to the carpeted floor, careful not to crush the human underneath. She kept her legs spread without a care, and her slimy Princess cock, finally gone soft, lay quiescent against the mess of her chest.
“I’m glad you took the initiative, little pony. That was lovely. I haven’t had anyone so…enthusiastic about my tight asshole in many years. I hope you enjoyed yourself, too.”
There was no response. Celestia peered down between her thighs. “Doctor?”
Mary was staring at the Princess’ fat ass while clutching her cunt with one hand, as if she could hold back the cream still dripping down her thighs. She rose to her feet on shaky legs and touched Celestia’s left buttock, feeling its heft, its softness.
Moaning with need, Mary embraced the sun-emblazoned rump with her whole body. As Celestia watched in amusement, she began to hump her enflamed pussy against the insignia like an animal in heat, rubbing her juices against the pliant flank. Her mouth was gaping, her tongue lolling, as she tried desperately to scratch an itch she didn’t know existed until tonight.
“You seem frustrated, doctor. Unsatisfied.” Celestia wore a wry smile as she allowed Mary to fuck herself on her ass cheek. “Is there something else you want? Something you need? Speak your desire, and I’ll grant your wish. But you have to tell me true.”
Mary’s breathing was shaky as she slid her reddened cunt lips up and down against the very symbol of Celestia’s power and authority. “I can’t…oh god, I want to…” She began to move her hips faster, her eyes fixed on the alicorn’s musky anus.
Teasingly, Celestia spread herself wide, the better to show off the delectable hole within. Mary began to whimper, reaching out one hand to stroke the dark ring as her thrusting became deeper and more insistent. It was as if she was trying to…
The Princess ahhed with new understanding. “I see. You want to mount your pretty horse, don’t you?” Her voice was low and sensual. “If only you had a cock, hm? If only you had a big fuckstick like mine to shove into a warm hole so you can get off for real. I’ll bet it could be anyone. You’d probably fuck Erin over there if she was in front of you-“
“No!” Mary shouted in-between grunts. “I want you. I…I have to fuck your ass. Please. I have to feel it.” Her fingers sank into Celestia’s clenching anus, and the sensation caused the alicorn to hiss with her own need. “I want to know what it’s like when you…take someone. Let me get off in your asshole. Please.”
Mary’s desperate begging caused Celestia’s cockmeat to twitch, and she licked her lips as she responded to the human’s pleas. “All right, shhh, it’s okay, little pony. I’ll give you what you need…what we both need.”
The Princess’ horn glowed with brilliant pink energy, and Mary stumbled backwards as she felt a strange sensation in her crotch. The pinky-sized nub of her clit, already big for a human, began to expand and lengthen to the size of a normal prick before growing far beyond. Soon it could no longer be confused for a human cock, with a flared tip and pink mottled skin similar to Celestia’s.
Mary touched the tender surface of her new equipment with trembling fingers. It was scorching hot, too big around to fit both of her hands, and almost as long as the Princess’ monstrous cock. She stroked along its length tentatively, and the weird new feelings almost made her collapse in ecstasy. If she didn’t stick her new fucktool into a sticky pussy or tight asshole soon, she thought she might die from want.
Celestia turned around in place, sinking to her knees and lowering her head, raising her massive buttocks to place herself in the age-old fucking position. Legs wide, she flexed her thighs, clapping her ass cheeks in a mate-attracting display of submission.
“Come and take what you want, doctor. Fuck your mare in the ass, stretch me out with that magic cock, and don’t stop until you’ve made a mess of my bowels. You want to understand what it’s like to be me? Go ahead. Feel what I feel.”
There was no hesitation. Mary launched herself at the offered hole, clambering upon Celestia’s lower back like her ancestors climbed trees. She slid her shaft against the soft crease of the Princess’ plump butt, almost crying at the divine warmth, but that was not her goal. Guiding it with a shaking hand, she pressed the tip of her new cock against the alicorn’s tight rosebud, causing both of them to gasp and moan.
Mary pushed and shoved, grunting with exertion as she forced the wide tip into that sucking anus. With a wet pop, the head entered Celestia’s clutching hole, and inch by inch, the human sank her twitching rod into the Princess’ upturned rear entrance.
“Fuck, that’s…bigger than I expected,” Celestia gasped. “Yes, get your pleasure from my ass, that’s it. Force me to take your…ohhh…your giant cock in my tight little hole. Do it, horsefucker. Take your mare like a stallion.”
True to Celestia’s instructions, Mary snorted like the animal she resembled as she drove her sorcerous organ deeper into the alicorn’s guts. She wasn’t trying to make her partner feel good, and there was no affection in her actions. This was ass-fucking, pure and simple, with the express goal of getting her own rocks off. There was nothing else in her head, nothing but the sights, sounds and smells of a big cock plunging into a warm hole.
All she wanted was to come. More than her Ph.D, more than her career, more than anything else in her life, she just wanted to come!
Princess Celestia was not a passive participant in this obscenity. She spread her thighs and worked her fat ass up and down in time with Mary’s short, jerking thrusts, doing what she could to ease the massive invasion into her colon. There was no in-and-out pumping into that squeezing tunnel, no hip-shaking, stomach-rocking clapping of cheeks. Only an unstoppable slide into those dark depths, one agonizing inch at a time.
Demonstrating her skills further, the alicorn worked her rippling interior muscles around the horsecock in her ass, caressing Mary’s flesh with sticky anal sweetness. The human wailed at the blissful currents flowing around her invader, and her thrusts became shakier and less controlled.
With lust-hooded eyes, Princess Celestia looked back at Mary’s body, splayed out on her twin suns and shaking in absolute pleasure while her lower body jerked and shoved, as if she were trying to immerse her entire self into that perfect asshole. The biologist’s teeth chattered as she grasped at the fleeting tatters of her own rationality, only barely able to think amidst anus-destroying bliss.
“God…oh, god…my cock, you’re sucking my fucking cock with your asshole! It’s better than I dreamed…fuck, too good, I can’t…how? Princess…Princess, how do you stay sane?”
Celestia said nothing right away, only increasing the rippling pulses of her deep, dark hole, watching the play of emotions on Mary’s face as she worked the human toward her conclusion.
“I’ll admit…ahh…I’ve cheated a bit, doctor. I’ve had a long time…ah, fuck…a long time to learn how to give anal satisfaction. Though, in a way, I’m jealous. I’ll never feel what it’s like to fuck an ass as…mmm, perfect as mine, so I guess you’ve come out ahead.”
Mary scarcely heard Celestia’s words. All her attention was on her cock, and the rapidly rising tide of her magical orgasm. It felt as if she were being turned inside out, with all of her senses focused on the slab of meat immersed in the Princess’ heated chamber. Foreign muscles twitched and squeezed, causing roiling waves of pleasure to travel from her fat fucktool right to her addled brain.
Deeper, hotter, juicier…and then, joy.
Celestia had not granted Mary any testicles, not even human-sized ones, let alone the same mammoth nuts that swung between the Princess’ thick thighs. As such, there was no explosion of hot come into the alicorn’s welcoming backside, no belly-bulging deluge of cream soaking her large intestine. But as Mary locked eyes with Celestia in the midst of that shattering climax, she thought she finally had a deeper understanding of the ravenous urges that the Sun Princess narrowly kept at bay.
Celestia smiled, seeming to read Mary’s thoughts. “You feel it. The drive to fuck and breed and dominate…pony or human, it’s universal. Magic only enhances that state. Think of it as the perfect…mmm…aphrodisiac.”
A force multiplier. That’s what magic was at the root, growing exponentially stronger depending on the user’s personal strength and…proclivities. Even a weak human like Mary had almost lost her mind after experiencing her new cock’s mystical pleasure, entirely due to her own dark, bestial fantasies. And even then, she’d managed to hold onto her sanity.
For someone like Celestia, an existence swirling with magic, with powers and experiences that humanity could only dream of, the urge to indulge in her lusts to the exclusion of anything else would have been overwhelming. It was a testament to the Princess’ towering willpower that she managed to keep her fat fucking cock from spreading out the cunts and asses of every creature that crossed her path.
And even then…Mary’s thoughts went to Erin behind her, disassembled body and soul by Celestia’s thick pussy splitter. Sometimes, that willpower failed, leaving behind a ruined fuckhole.
Mary wanted to be ruined, too.
The realization sent her into another spasming orgasm, just as strong as the first. Celestia gave the human an impressed chuckle as she felt the imposing length throb inside her ass. She rode it out with her lover, cooing and shaking her sun-kissed flank as she felt Mary peak, then come down the other side, groaning in tired satisfaction.
Mary drew her length out of Celestia’s ass gingerly, trying not to set herself off again, lest she die of exhaustion. It took a good minute, but Celestia helped her along, wriggling her anal muscles to help extract the thick tool from her enflamed asshole. The swampy, sucking sound was overly loud in the quiet room.
When she’d pulled herself free, Mary bonelessly slid down the curve of Celestia’s massive rump, stumbling backward a few steps before landing with a squish onto her own bubbly butt. Her giant rod flopped against her chest and tits, soft and spent, then it began to glow with pink radiance. With a flash that momentarily blinded her, the magic cock vanished, leaving only her own hairy fuckhole. She was still so drenched, so creamy.
The biologist collapsed onto her back, her arms outspread, the tatters of her black cocktail dress still bunched around her narrow waist. She was covered in sweat and breathing hard, unused to such sexual exertion, yet she watched closely as Celestia rose to her hooves and came about.
Three feet of thick Princess cock appeared before Mary once again, titanium hard and ready for action, thumping impatiently against the alicorn’s barrel and flinging sticky precome across the carpet in front of her with every jerk. Oversized balls rumbled, preparing gallons of scalding spunk for Celestia’s next conquest.
Holding Fast and Letting Go
The Princess regarded Mary, splayed on the ground like a martyr. The human in turn looked up into Celestia’s diamond-bright eyes, knowing what was coming, and accepting her fate. She would accept anything that was given to her this night, without reservation, without hesitation. She would take it all.
“Why me?” She whispered the only question that remained.
Celestia’s entire body vibrated like a taut string as she looked down at the piece of human fuckmeat writhing on the floor, and she showed her teeth like a beast as she took in the scent of overheated pussy. “Vorfreude. Vorfreude. You want to know why I turned you out?”
The alicorn shuddered. “I could tell you it’s because you appreciate magic for the beauty and passion that it represents. I could also say you have a shockingly high compatibility with sorcery, higher than any human I’ve seen yet, and I want to convince you to become my pupil. By fucking you. I’m fairly persuasive in that way.”
Princess Celestia took a half step closer. “But those reasons are secondary. The truth is, I saw the want behind your eyes. The fucked-up fantasies unfulfilled, the holding back of your real self in the face of ridicule.”
She took another step. “You’re a filthy horsefucking anal slut, Dr. Mary Parvotti. I wanted to experience that part of you for myself. And now that I have, I need to possess all of you. I’m afraid I can’t hold myself back any longer, little pony.”
Celestia’s horn glowed a soft white, and Mary heard a thunk as the lock on the front door disengaged.
The Princess was panting now, and her hips were thrusting subtly, her fat fucker searching for a wet hole. “This is your last chance. You have no idea what it’s costing me to keep from…oh, Mary…you need to hurry. If this isn’t what you want, run. Even if a relationship between our people becomes impossible, I want to give you a choice. Now, make it. Before it’s too late.”
No hesitation.
Mary spread her legs in a wide V-shape, tilting her hips upward as she presented her steaming cunt to the predator above. Her feet hiked into the air, with her sleek black panties inexplicably still hanging onto one slim ankle.
“It’s already too late, Princess,” she moaned. “It was over when I first saw you…you and your goddamn big ass. I never really had a choice at all, and neither did you.”
Mary reached down and spread her slippery pussy lips with both hands, revealing her frothy, cream-filled core. She tried to remember the feel of her untainted hole, resigned to the fact that it would soon become unrecognizable.
“It’s all right. I’m glad it happened this way. Now, hurry and fuck me. You don’t have to think about anything else tonight, just do what makes you feel good. Use my body to drain your fat nuts.”
Her voice was silk soaked in cunt juice. “Set yourself free, Celestia.”
A curious sound came from deep within the Princess’ pure white throat. Mary didn’t figure out what it was until the alicorn was almost on top of her, her muzzle right in her face and drool dripping onto her cheek, when the answer became disturbingly clear.
She had never heard a horse growl. She didn’t even know it was possible. Hearing a majestic specimen like Celestia make such a base sound was like seeing the Queen of England get on her knees and start barking like a dog…which wasn’t too far from the truth. But the nation she represented was the last thing on the Princess’ mind at the moment.
Looking down between her spread legs, Mary watched with pleading eyes as Celestia kissed that inhumanly wide flare to her very human cunt, starting a slow but insistent pressure. The entire length of her cock pulsed at it spurted a jet of precome into the dripping slot, merging with the creamy juices already there to form a lubricating ambrosia that leaked out around the tip, as heady as any wine. Mary couldn’t take her eyes off the unreal sight.
“Princess.” She said it more insistently as the force increased. “Princess. You’re gonna wreck my little pussy.” It was a simple statement of fact. When Celestia ignored her pleas, Mary felt something give inside her, and splashes of urine joined the frothy mixture gushing out of her cunt. “Princess!”
There was nothing left to discuss.
Celestia almost looked pained as she worked her broad tip into Mary’s narrow hole. “Fuck…all you humans are so fucking tight…let me in, little pony. Open up your pussy and take this Princess cock. You’ll take it one way or the other, so don’t fight it, just let it happen.” As she gave another hard shove she growled again, a deeper and more dangerous sound than before. “I said, open up your pussy! Open up your womb !”
Mary felt an unnatural sensation as her messy cunt stretched wider and wider, preparing to admit that big flare. She knew something was about to happen…something strange, something magical. Her wandering hands, sticky with sex juices, grasped the wide edges of Celestia’s cock tip, pulling inward with all the meager strength she could still muster in an ineffective attempt to speed things along.
“I’m trying! I know I have a tiny little twat, but I wanna take it all! I wanna be a good little fuckhole for you, but I have to…you have to fuck me up first.” She began to babble as Celestia’s thick tip worked itself into her narrow tunnel. “Oh, fuck! Oh, god, make me take it! You’re the Princess, you can do whatever you want! You can fuck whoever you want! Princess cock can break anything, so break this weak little human. You’re royalty, so fucking act like it! ”
That last outburst made Celestia snort in anger. With one more determined push, she squeezed her gem-hard fucktool into Mary’s clinging cunt, making both lovers scream each other’s name as they connected themselves at last.
Celestia was panting and blowing as if she were running a marathon, working her broad hips and ass to squeeze every bit of herself into Mary’s newly elastic hole. “Mary…I never knew…so tight…so wet…what are you doing to me? Is this magic? I need more, I need…I need you …I can’t stop!”
The Princess pulled her hips back and crashed forward, plunging her massive tool deeper into Mary’s accepting cunt. She did it again, harder, faster, and then she was fucking, slamming her fat hindquarters into that silky wet pussy again and again, going deeper and deeper with each thrust.
It shouldn’t have been possible without pain. Mary should have been terrified at what Celestia’s magic was doing to her body, but there wasn’t the least hint of fear. Even as the bulge of the Princess’ impossibly thick horsecock, still spewing precome, moved past her stomach and into the space between her breasts, she trusted her partner to keep her safe, more or less. Of course, nothing was guaranteed, but the thought of Celestia doing something unspeakable to her while lost in her own pleasure only made her squeal harder.
“Look! Look, I’m taking it!” Mary screamed. “I’m a good girl, Princess! Wrap me around your cock, use me like a jizz rag! Make me remember what you did to me!”
Then, she felt it. A steady beat, right around the center of her back, pulsing rapidly with her exertion. It was regular and loud in her ears; whump-whump, whump-whump. It sounded familiar.
The space between her breasts…?
Mary looked at her chest, taking in the shattering sight of Celestia’s fat tool distorting her skin. Where her heart, lungs, and other organs should have been, there was only 18 inches of grade-A, cunt-breaking horsecock taking up far more space than was physically possible. She could feel the drumming of her racing heart in her back, just below her neck.
Magic. Sun Princess Celestia had indeed molded her body to fit her exclusive use, making her into a perfect little royal cock socket. Her organs had been shifted haphazardly, unimportant in the face of the Princess’s carnal urges. Mary knew it had to happen that way: nobody, not even ponies, could take Princess cock and live without magical flexibility. But she ignored the objections of Dr. Parvotti. Only one thing truly mattered.
“Thank you!” Mary shrieked, tears rolling down her shaking cheeks. “Thank you for making me your fuckhole! Thank you for destroying me! Thank you, Celestia! Thank you for using my sloppy cunt!”
The Princess continued to fuck. Her mouth was slathered in foam like a rabid wolf, eyes gone white in their sockets. She knew nothing except the desire to dump her load into her bitch. Mary saw that there was still a good few inches of thick cock left outside her sticky, creaming cunt, and she despaired for Celestia, seeing how much not being able to hilt herself frustrated her.
She raised her jerking arms toward Celestia’s head, touching the side of the Sun Princess’s muzzle tenderly. Her fur was so soft, more comfortable than the highest quality cashmere, and her flowing mane was a riot of color above the Princess’ straining form.
Then she grasped Celestia’s horn, tentatively stroking it with both hands. The Princess grunted in surprise, increasing the pace of her jostling ass, and as Mary caressed that white spear faster, the sound of Celestia’s pendulous balls slapping the human’s ample butt grew louder and faster.
Mary cooed like a mother as she tried to get Celestia to look at her, wondering if she still remembered the person named Mary existed, except as an incidental existence attached to a cock holster. “Princess? Come back to me. Look, look at what’s happening. You’re missing all this pleasure. Don’t just let one side of yourself have all the fun.”
She tenderly ran her fingers across the alicorn’s opened mouth, feeling her scalding hot breath on her sweat-soaked skin. Mary touched Celestia's lolling tongue, the inside of her cheek, and even the edges of her ultra-sharp teeth, and every moment of contact was full of love.
“I want you here, with me. Please, Celestia.”
The Sun Princess’s giant pumping ass slowed, then stopped. Mary felt her lover’s tongue almost timidly returning her fingertip’s caresses, and the human held her breath as Celestia blinked, her eyes returning to their original brilliant hue. The Princess looked down at Mary, and a plain look of shock was on her face. It was a true reaction from a being who made hiding her emotions into an art form, and Mary rejoiced as they once again recognized each other.
Holding Celestia’s gaze as if afraid to lose it again, Mary grasped the sides of her equine head with both hands. With the last of the strength in her tired arms, she drew that large muzzle toward her own opened mouth. Allowing herself to be led, Celestia’s long tongue snaked out, and Mary captured it between her own ravenous lips, sucking on it as if it were a delicious candy.
Mary truly felt like a horsefucker now. The two delighted in each other’s tastes and touches. Joyful ripples went though the biologist’s invaded channel, massaging the Princess’ resting cock, but Mary knew her thirsty cunt would not come yet. Not until Celestia had taken her pleasure.
They both stared at Mary’s hands as the human reached down, touching the inches of cold hard cock still left. She couldn’t even begin to reach all the way around with ten fingers, but soon that would not be a problem. As one, they looked up into each other’s eyes, shocked as they saw each other’s sex-crazed expressions, but then the moment passed, replaced with an instinct so urgent that the end of the world would not have drawn them away from each other.
At last, Mary knew Celestia’s true intentions. Putting her soft lips to the alicorn’s flicking ear, she quietly gave a very simple command, the only command she could possibly give a Sun Princess.
“Breed your little pony.”
With an incoherent roar, Celestia planted her back legs on the ground and reared up, pulling Mary along with her, still impaled on that spire of pulsing fuckmeat. Still on her hind hooves, the Princess crossed the room in an instant, slamming Mary’s back against the reinforced glass patio door leading out to the rooftop, and the human felt a loud, rattling bang that took her breath away. Celestia placed her forelegs on both sides of Mary’s head as she continued to fuck—no, to rut—and the savage motions made the vestigial wings on her back flap with an unforeseen vigor.
In the corner of her eye, Mary saw the small, winking lights of the facility outside, with only the dark, unforgiving ocean beyond.
The whole world sometimes felt dark. There was light, yes, but that could be difficult to remember in the depths of the starless void which had been her existence at various points in her life. She craved that elusive brilliance, like a junkie craved a fix, and the moments of illuminated joy had been enough to keep her going, to keep her sane.
But as Celestia grunted deeply over and over again, struggling to force her juice-slick cock the rest of the way into Mary’s changed body, the human began to realize that the meager light she was used to was like a candle against the majesty of the Sun. She no longer wished to be without the Princess’ dazzling radiance, knowing that wherever Celestia went, there also went magic, and strength, and love, and lust…so much lust, complete and total, making her misaligned heart sing.
“Don’t let me wake up from this dream,” Mary whispered as she was pounded, not knowing that Celestia’s sensitive ears easily detected her words.” “Please, don’t let me wake up. Show me your sunlight, fuck away my night. You’re a buttslut whore who can’t keep her big fucking cock out of trouble, but nobody can stop you. So show the world…ah, God, Princess…show the world your power!”
Princess Celestia’s small wings began to flap quicker, though Mary would swear that they were now bigger than before. Her massive white ass churned as her frenzy increased, occasionally revealing the puffy, wildly fluttering asshole in-between jiggling claps. Mary felt no pain, only deep pressure and increasing heat, but the bulletproof window at her back was not even close to proof against alicorn might. She heard a series of sharp splinters and cracks, and spider-web fractures spread from the glass behind their conjoined bodies.
With a final bellow of triumph, Celestia gave one more massive shove, burying all three feet of fat Princess cock deep into the holster that was Dr. Mary Parvotti. At the same time, the patio door shattered, and squared-off shards of glass swirled about both their bodies as Celestia kept fucking, stepping out into the cold night air, exposing herself to anyone that happened to look in their direction.
“I’m a cock-sleeve!” Mary screamed into the night, though it seemed to be growing lighter despite the still late hour. “I’m a cock-sleeve, I’m a cock-sleeve, I’m a cock-sleeve, I’m a…” She repeated the phrase like a mantra, feeling Celestia’s thick hips touching her own with nothing in between. Only Celestia’s mysterious power kept that massive, throbbing tool from coming out her other end.
The Princess was still on her back legs, thrusting up into the waning night, and hearing the human’s delirious confession made her balls begin to rumble ominously. She spread her pale wings, now definitely bigger and longer, proudly displaying her latest conquest wriggling on divine Princess cock as she stomped around the rooftop, crunching glass underneath her gold-shod hooves.
“She’s belongs to me!” Celestia snarled to the heavens as the sun rose above the watery horizon, acting as a fiery witness to their consummation. “This is what you wanted, little pony. This is what you asked for, so take it! Fuck, my nuts ache…but this pussy…this sticky cunt hole, it’s not fair…drink all my come, little pony. Drink it with your womb and bear my-“
She never finished. Her balls drew closer to her cock, and before she could say another word, Mary heard the creamy, splattering sound of lovely come bathing her from the inside out. Those massive nuts flexed, and her wings trembled, now large enough to cover the surface of the roof in shadow. But the sun came out, and Princess Celestia began to glow too, banishing the rest of the night’s darkness.
Mary came. She clenched upon Celestia’s spurting meat, instinctively using her orgasm to work the precious seed from those mighty balls and that pulsing shaft. Thick cream splattered at their feet, while cunt juice and urine spewed helplessly out her ruined hole and down the crack of her ass, but Celestia kept coming until Mary’s stomach was bloated enough to be mistaken for a third-trimester delivery.
And still the Princess kept coming, giving everything she had to give to Mary, just like they’d both wanted. As she was throughly bred, she watched the ecstasy on the alicorn’s face. It was similar to the look of abandon Mary had seen when she’d first walked into the suite, but…better, more vibrant. The Sun Princess Celestia’s face was filled with light, the same as her own, and even as the impossible sunrise happened behind her, everything still felt right. Like magic.
Erin was back in her own room, none the worse for wear — physically, anyway — though at the very least, she'd have some kinky flashbacks for the rest of her life. As Mary figured, Princess cock was a dangerous thing. It would change you forever, and even if the flesh forgot, the mind would not.
The window was fixed as good as new, and the skies beyond were colored gray in the Atlantic morning. Mary felt a weird sensation as she looked out into the second early dawn, as if she’d slept an entire day away.
It seemed that adjusting an accidental sunrise took much less work than repairing a human’s splintered mind, and even Sun Princess Celestia was abashed at her lack of control.
“That’s never happened before,” Celestia was saying as she rested on her back, with Mary draped across the Alicorn’s large, soft-furred barrel. The human gently ran the fingers of one hand through that luxurious pelt, while the other stroked the Princess’ beautiful cock, now soft and draped next to her, curving to the right, with the flat, spongy head next to her nose. On a whim, she kissed the coin-sized hole on that cocktip, and a light drizzle of come slowly oozed onto Celestia’s still sticky chest. Though the Princess could have magicked them clean, they both found something incredibly hot about lazing around covered in their own bodily fluids.
“Bet that’s a new sentence for you,” Mary said in a sexy voice, causing them both to laugh, though Mary was almost too tired to move her diaphragm beyond the necessities of breathing.
“Indeed,” Celestia said, still grinning. Her right hoof stroked Mary’s head as the human continued to run her lips against the tool that made her, the cock that she loved, and that loved her in return.
Celestia’s smile wavered. “But truly, I have a lot of work to do to fix what I did. Resetting the orbit of the sun is the easy part, compared to what I did to Erin. I may have gone a little overboard, little pony.”
Mary chuckled. “You didn’t even make it to the bed, did you? Did she really get you so hot you had to fuck her in the living room?”
Celestia wore that serene expression again, but now it seemed like a genuine look of peace and contentment, instead of a mask. “I didn’t know if you would show up. It was 1 in the morning, and I needed to get my rocks off. I was pretending she was you the whole time, although-“
Her spent cock shuddered and lengthened an inch, spurting a cloudy jet past Mary’s shoulder. “It wasn’t even close to the real thing.”
Mary reached up to touch Celestia’s muzzle, seeing no lie in the alicorn’s words. She tried to think of an appropriate response, before chastising herself for her own foolishness. The truth had worked so far, so there was no reason to change her approach.
“You wanted to breed me,” Mary said quietly.
For the first time since they’d met, Celestia turned away in what looked amazingly like embarrassment. Mary found this adorable, and she went on with amusement, glad to have the Sun Princess on the back-foot for once. She couldn’t imagine how rare the experience was.
“I said, ‘wanted to,’ but of course, you went ahead and did it. I mean, nobody throws around Princess cock like that unless they want a bitch well and truly knocked up. When were you going to tell me?”
Princess Celestia kept her eyes averted. “If that’s not what you want, I can-“
“Did I say that?”
Celestia turned to face Mary with a start. Fear, thankfulness and shame fought each other across her regal countenance. The biologist’s heart, now back in its proper place, almost broke at the sight.
“I think…I guess I only have one question,” Mary said. She instinctively wanted to put the Princess at ease, but she had to know. “How much of your visit is really diplomatic, and how much involves spraying your come across the planet? How much is it ever?”
It was a fair question, and Princess Celestia knew it. She replied with only a slight hesitation.
“The diplomacy is genuine. I wasn’t lying when I said how much I enjoyed meeting new species. I’m a scientist, too, in my own way, and I have just as much interest in xenobiology as anyone would in my position. It’s only a quirk of fate that I’m in a position to indulge my hobbies.”
“Lucky you,” Mary said, tapping the tip of the Princess’ cock playfully. Celestia hissed as her cock grew a bit thicker.
“Speaking of indulging." The two shared a laugh at the Princess’ hair trigger.
“I know, I know. It’s just…what you have to understand is…” She turned her eyes away again, and this time it wasn’t embarrassment in her gentle face.
Mary gripped Celestia’s muzzle and pulled her back, forcing the Sun Princess to accept her gaze. “It’s okay.”
Celestia sighed in resignation. “It’s just that…alicorn spunk isn’t nearly as potent as you might think. Maybe once in a long generation does a pony birth another alicorn, and lately not even that often. I have lots of children running around, and I love them all, but until recently none of them were like me.”
The Princess was pensive as she spoke. “I was the last. We’d almost resigned ourselves to losing my magic, when we discovered mystic portals.”
Mary nodded, following her thread. “Crossbreeding.”
“I was as surprised as anyone,” Celestia said, smiling at the memory. “The chances are still low, one in a thousand, but it might as well be guaranteed compared to what it was. And all of my little alien children become alicorns. Every single one.”
“Ugh. I hope I don’t get something bursting out of my chest.”
“Don’t worry,” Celestia said, laughing openly, sweetly. “You’ll have the best medical care on both sides of the portal, I guarantee it. But you can scream ‘Get away from her, you bitch’ while you come on my cock if that's what gets you off.” Mary tried her best not to laugh at this image, and she failed miserably.
Yet Celestia hesitated again. “You would bear my child? Knowing my motivations?”
“One hundred percent,” Mary said with conviction.
“And you’re not…weirded out, or…”
“Are you serious?” Mary said incredulously. “No. I’m not weirded out. If I can bring someone like you into the world, I’ll take Princess cock as many times as it takes. Just bend me over and do it, whenever you get the urge.”
Mary felt a low rumble deep within Princess Celestia’s barrel, and she looked on in amusement as that fat breeding tool raised and lengthened, now approaching its full size.
“Don’t make promises your sloppy cunt can’t cash,” Princess Celestia said roughly as she pawed at Mary’s body possessively.
“Try me. But I’m not talking about my pussy right now,” Mary said with a challenging glare, slurping up the leaking cream now dripping down Celestia’s fat shaft.
The Princess gave a shuddering moan. “I don’t…mmm…think it works that way.”
“Bullshit,” Mary said, continuing to lick as she pawed at her own drenched cunt. “You shoved my heart into my spine. I think you can make a pregnancy happen through my throat if you wanted. Or my ass, for that matter.
Celestia’s hips began to lurch. “Be careful,” she said with menace, not entirely playful. “I might lose it and shove my thick fuckstick right through your body.”
Mary stroked and sucked with increasing passion. “Then you can fix me,” she said, lips smacking against that massive tool. “You can do whatever you want with me. I trust you, Celestia. But we only have an hour before we need to head to the next briefing. Are you up to it?”
“Now who’s slinging bullshit?” The Princess grunted thickly as she grasped the back of Mary’s head against her hoof, drawing the biologist’s drooling mouth closer to the tip of her royal cock. They ended up reasonably prepared for the next event, but only just, and Mary found herself administering the important meeting with a belly full of alicorn spunk. She found she liked the way she looked paunched with come, imagining a very different type of bump, though she didn’t know how she’d explain her possible future pregnancy to the higher-ups. Well...they’d figure something out. Sun Princess Celestia was a deft hoof at diplomacy, after all.
Dr. Mary Parvotti never expected to be a mother, especially with a dimensional traveler’s foal. But the night was full of firsts.
