The meeting Chapter 1.
“Everybody ready?” asked Blitzo as the final preparations for the job were finalized. “Millie, you have your ax? Moxy, Loona, grab the book, come on.”
He shook his head and looked at his small note of horse drawings and the list of things to do:
Step 1. Kill Celestia  
Step 2. Buy Loona a birthday gift  
Step 3. Don't die while doing either  
Step 4. …  
Step 5. Money
“I'm still eating my breakfast, damn it!” barked back Loona, spooning away at her Cheerios. “Why’s this job matter so much, anyway?”
“It doesn't matter what the job is, it's our job!” spat back Moxy as Millie twirled her ax in the background and Blitzo rubbed his temples for a moment. “Besides, he told all of us what time this was happening, two days ago!”
“Loony, please, this job is the biggest paying one we've ever had,” pleaded Blitzo, drawing a sigh from his adopted hellhound as she set down her food. “Just… try to put some heart into murdering today?”
“Let me put on some clothes,” she sighed, dragging herself up.
Moxy averted his eyes from the dog girl casually wearing her collar, panties and bra and nothing else. “I can't believe you just let her walk around like that, sir,” he sighed as she went to the office to make herself presentable.
“Moxy, do me a favor and shut up.” Blitzo was used to the sight, as that was her usual at-home attire. “Besides, she's dealing with a hangover. Though, I wish she’d come home instead of the office last night…”
Millie stayed out of the argument. She just didn't give a damn.
It wasn't long before Loona came out in her typical gothic attire; her crop top pentagram boob window shirt that showed off her melons, and her short, ass-hugging shorts.
Everyone gathered together around the book and Loona spoke the chant, opening the portal that would take them where they wished to go. It swallowed them all, placing them in the throne room of Canterlot Castle.
“Alright, bitches!” shouted Blitzo. “We can do this the easy way or th–”
He stopped short. Celestia, Luna, Twilight and Cadence, all naked, had been talking amongst themselves, and now looked to the intruders with raised eyebrows.
The imp only took a glance at their forms, gathering plenty of information from their vibrant coat colors to their… sizes.
Not just their bodies, but their breasts ranging from Twilight’s little less-than-average bust, followed by Luna’s decently-beyond-average chesticles, to Cadance’s melons, nearly twice as large as Luna’s, like two soft, squishy pillows on her chest.
But they were all overshadowed. Celestia's titanic gravity wells dwarfed the others, being nearly three times as large as Luna’s, making Twilight seem imperceptibly flat. Her areolas alone were the same circumference as Twilight’s whole breast, each with firm, plump nipples almost too big to wrap a set of lips around.
Some of the royals had piercings as well. Some crescent moon earrings had been stuck into the lobes of Luna and their solar equivalents were worn by Celestia. Both also had matching belly button piercings.
What separated between them was the nipple piercings. Where Luna simply had two studs on either side, Celestia had the much more brash-looking piercings; two golden handlebars hanging from her tits.
Cadence wasn't clad in any piercings, nor was Twilight.
Those wonderful breasts and piercings were quite eye-catching, but they weren't what drew the imps’ and hellhound’s attention the most. Their eyes drifted to the hips of the monarchs.
Twilight’s slimmer figure was the opposite of thick, but still her hips gave her a nice hourglass shape, with her butt firm and soft-looking. Cadence’s hips and ass, much like her tits, were an expansion on Twilight’s sizes, providing a nice, heart-shaped rear that one could give a good squeeze and lose their muzzle in.
Things took a turn for the crazy from there. Luna’s hips and rear combined were certified clothing-tearers, big enough that she’d almost end up stuck in a lawn chair built for her size. Her ass cheeks were so large that they might as well be pillows, and honestly, probably worked well enough as such for whomever was lucky enough to find themselves in her bed.
Then there was Celestia's cake. It was big enough to fit a three-tiered wedding cake inside of each side of her fat rump. Truly, two beachballs worthy of the sun cutie mark on each cheek. It was several times the size of her dear sister’s plot, and rotund enough that one would likely lose their head under them and suffocate before they made their way out of the solar cheek trap.
What everyone finally focused on as the group of alicorns turned to the imps and Loona were their cocks. More specifically, the sheaths and balls hanging between and pressing against their thighs.
Twilight and Cadance’s sheaths, and of course the cocks within, were of fairly tame sizes as they rested. Veiny, and in Cadance’s case, seemingly always dripping with precum, they rested over the fat nuts of the younger alicorn princesses. Each of their ballsacks were somewhere between the two mares’ bust sizes in their enormity. On each, the veins of the beastly things they wielded like weapons were visible, if not pronounced and pulsing, as they snaked to the head of the sheaths to meet the medial rings, neither absurdly thick in their circumferences; just a bit beyond average in both cases.
The real titanic girths were, to no one’s surprise, on the alicorns representing the sun and the moon. Celestia's sheath was thicker than an arm, coming out to almost a foot in length, clearly hiding a truly massive member within. It rested on the two heavy, leathery white orbs she called nuts; as big around as cantaloupes and then some. They rested on her thighs, dripping with sweat.
Loona’s eyes, unlike those of the imps, fixated on the piece of black and dark blue meaty phallic sheath hanging from Luna’s crotch. It seemed a bit smaller than her sister’s covering, but not by much, and both were quite veiny beasts. She watched it lightly twitch, leaking precum, a deep blush coming across her face.
Blitzo grabbed Moxy and Millie, immediately turning them all to face inwards as Loona shook herself from the heat-inducing stupor and kneeled down into a crouch, still firmly taller than the imps, leaving her exposed as all hell.
“They’re all naked horse ladies!” proclaimed Blitzo in a shout-whisper. “Nobody said that they’d be horses!”
“Sir, I think you’re overlooking the much more pressing strangeness.” replied Moxy, raising his eyebrow. “They are women; or, I guess mares, with dicks. You’re fine with murdering seemingly innocent individuals on regular occasions, but not horses? That's your concern?! They’re naked ladies with their dicks out!” he emphasized, throwing his hands out from the group to the alicorns, “They have dicks!”
This made Loona look up at them, clearly unsure what to think of the motley crew that had come before them.
“J-just… don't draw your weapons yet,” Blitzo said, turning back around.
Loona rose up to look at their target, standing there: an eight-foot tall, winged unicorn lady that was even a bit taller than Loona herself, even if most of that height was her horn.
That said, her gaze didn't focus on her for long as her eyes drifted to the next tallest alicorn, blackish-blue in color, unlike Celestia's alabaster and porcelain white coat, with a starry mane of the same design as the memoir she was holding. She stirred something in Loona.
Almost all of them did, actually, but the blue one most of all. She felt her panties starting to grow a bit tighter and she gulped lightly.
”I want to fuck a horse lady… That's a first,” she blushed.
“Hey, there, dear equine ladies. My name is Blitzo. The, uh… o is silent. Ummm… this is my crew, and we're here on a, uh…”
“Interdimensional outreach!” spoke up Loona to the surprise of most of the imps, prompting a light shrug from the hound as Blitzo focused in on her blush. Was she… towards them?
“Huh… Uh, yeah. Outreach. And as we understand it, you all are this land’s rulers, right?”
“Yes, that’d be correct,” answered Celestia, stepping forward, her white body shining in the light of the stained-glass windows. “And you are?”
Blitzo cleared his throat while Moxy tried not to stare. Millie helped keep him busy. This left just Loona, who couldn't not look at those plump, fat breasts hanging off her chest. They were larger than her own by a fair few sizes, as she was somewhere between the smaller two.
“Well, we're, uh… you know… we are from hell…” Blitzo said, expecting an immediate reaction but only receiving a look that asked for elaboration from the solar monarch.
Blitzo was cut off as Loona stepped forward to speak. “You don't know what hell is? Are y–”
“Ma’ams, I can tell we've, eh, interrupted something, so do you have a place where we can maybe collect our thoughts and talk when you’re free?” asked Millie, tired of seeing her boss flail about with words.
“Yes, we can grant you a temporary room,” answered Luna, stepping forward. She nodded to Loona and finished, “But this one stays with me.”
Celestia turned to address the other princesses. “Cadance, Twilight, we’ll pick things back up later, if that's alright with you.”
“It's fine, aunty,” smirked Cadance. “Besides, based on the look that the hound has in her eyes, you’re gonna need the place to yourselves.”
“Cadance!” jabbed Twilight with a bit of shock. “We’ll be back tomorrow, if that's okay with you,” sighed Twilight, blushing at her sister-inlaw’s blatant innuendo.
Celestia had known this was coming the second she had seen Loona’s blush. “I'll see you two tomorrow.”
Meanwhile, Blitzo was fuming. “Absolutely not! I'm not going to leave my Loony alone w––”
“Sure,” Loona flatly interrupted, to Blittzo’s dismay. Everyone kept cutting him off. He crossed his arms as Loona looked back at him. “Don't worry, I'll be fine. You know I can handle myself.”
Blitzo “relented,” fully intent on spying on the royal alicorns talking to his daughter as guards came into the room, escorting the imps out.
Hearing the grand doors shut, Loona turned back to the two celestial embodiments. “So, what did you want with me?”
At Loona’s question, the alicorns turned to each other inquisitively, almost competitively. A sly, cocky grin came to Celestia's face as she brought a hand to her mouth, lightly resting on it and caressing her chin thoughtfully with a finger. She mouthed something to her sister, who had been composed, but suddenly, a deep blush enveloped her face and she spat back with far less tact and composure.
She stumbled with her words for a moment, stammering, before crossing her arms and looking away from her sister defiantly, much to Loona’s confusion at still having not been given an answer.
“We… we suppose that, as the one she's eyed most keenly, I can be “saved” ‘til after you’ve become more “familiarized” with her,” conceded Luna with regained dignity and composure, despite her blushinging as Loona looked at her.
Celestia clapped her hands loudly, drawing the hounds attention. “Splendid! Fret not, dear sister. I promise I won't break her.” An additional statement followed under her breath, either not accounting for Loona’s greater hearing or not caring: “Not too badly at least…”
Now, Loona was no foolish dog. She could smell what was coming from a mile away, in more ways than one. Ever since the quartet had entered the room, she could smell something that the others couldn't; the powerful musk of four hung alicorns. She’d be damned if it wasn't working her up.
The sight of four, now two, tall and well-hung women, as weird as that statement was, began making her pussy quiver. It was a good thing she could tell what they had planned, though deciding how she felt about it was another story.
“You ponies know anything about modesty, or does everyone walk around naked, here?” she asked as she stepped forward, very matter-of-factly. The growing wet spot in her pants was impossible to hide away from the two monarchs..
“Oh, no, not everyone does, but I expect you to strip the second you enter our chambers. That is, assuming you are willing, my canine friend…” purred out Celestia, her magic pulling the hound forward by her collar. Despite Loona’s best attempts of stopping herself from moving, her feet only served to slide against the polished tile floor until she was released, mere inches before the two alicorns.
She was hammered by their scent at her first whiff. The musk wasn't sweet; rather, it was pretty pungent and overwhelming. But whether it was magic or a secret kink in Loona’s soul, it made her heart beat harder and her tail wag, despite her own efforts holding it down. She at least slowed it, only serving to let the wagging, sensitive tail beat back and forth against her thighs.
“W-well, I suppose a round or two wouldn't hurt before we talk about me and my, uh… “friends.””
“Hmm~ We think you'll like this very well,” purred Luna, walking around the hellhound like a shark sizing up its prey. “What is your name, hound?”
“Loona.”
At the proclamation of her name, Celestia couldn't have held back her grin if she'd tried. “Make that three rounds! I have something I really want to try in your dreams tonight, Luna.”
“Dreams?” questioned Loona. She was silenced by a finger against her muzzle. Her ears suddenly folded back for a second as Celestia booped her and she fought back a growl, pitifully failing and drawing a light chuckle from the two.
“Quite the feisty one, it seems,” purred Luna, grabbing Loona’s crotch. No pair of shorts in all of Hell could protect her from the fingers pressing against and rubbing her pussy’s folds the way that Luna’s fingers did. A gasp escaped the surprisingly virgin teen and Celestia’s magic quickly snapped the hellhound’s muzzle shut.
“No moaning ‘til we're in bed, you hear me? Otherwise you'll be punished, understand?”
The response was delayed as Loona reluctantly nodded. Magic took the place of Luna’s fingers as the two alicorns began carrying their new hellhound by her cunt and muzzle with their magic. It felt like they were using their actual hands, giving the feeling of being fingered for ten minutes as they walked through the castle with Loona not being allowed to moan.
This was going to be a fun evening… for someone.
The imps and Loona from Helluva Boss find themselves in a tricky spot when sent on a mission to kill none other than Celestia. Well, tricky for the imps because Blitzo loves horses and is a complete brony, and tricky for Loona because the princesses are hotter than all of Hell, and it's kind of hard to kill someone dominating you in bed.
It was supposed to be quick and easy, but she will find that it’s actually very hard.

         Loona will be sore after this Chapter 2.

Loona will be sore after this Chapter 2.
Resting in the chambers of the two royal sisters, Loona simply sat down and kicked up her feet. She’d been left to wait here while the two alicorns “prepared,” whatever that could actually mean in this context.
The room was quite large. There was a heart-shaped bed that was certainly big enough for a dozen, perhaps even two dozen ponies, not just the alicorns. Although, given the stench of sex and musk in the air that made Loona feel a bit light-headed, it was clear this chamber was built just for love-making, whether it was two ponies or twenty at a time.
Loona had been stripped of her garments, with Luna carrying them off when the two alicorns left her by her lonesome. Loona had taken this chance to snoop around, of course. She was able to see out to the streets of Canterlot below and the nude populace that was clearly unconcerned with clothes in their day-to-day operations, the few she saw clearly more for style than anything practical.
That said, her snooping couldn’t be pushed to attempt escaping her horny predicament. She’d tried hitting the window with a chair a few times for example, both of which were reinforced with magic and automatically repairing the tiny scuff marks she put on them through her few tries.
The bed was magically reinforced in the same way, something she learned by kicking it out of frustration and damaging her foot far more than the bed. Of course, this only made her madder at it, and by the time the door flung open with a burst of light and harmonious choir from somewhere undefined, she was in the middle of chewing and clawing at the headboard as it repaired itself.
Stepping in as her guest for the night pulled herself from the headboard, briefly on all fours, Celestia couldn't help but chuckle at the sight. “I see my new bitch is already down on all fours for mistress.”
“What?!” Looking at herself in realization, Loona hopped off of the bed. Before she could make it to the floor, an ethereal yellow magic gripped her wrists and heels, forcing her straight back into bed on her backside. A growl escaped the hound as she pulled at the force, not able to budge an inch.
“Oh, calm down. You’re quite the fighter. Definitely more Luna’s type, but I've always had a great deal of fun making arrogant bitches such as yourself submissive and subservient,” purred the solar empress, her eyes dancing over Loona’s black and white body.
Her form was much less extravagant compared to the princesses; closest to Twilight and Cadence with tits smaller than her head, they were good hand-fillers still, and nothing to scoff at. Loona’s hips were much the same, with her real blessing clearly being them and the weapon mounted on her crotch. The hound’s hips were each individually wider than her hourglass-like abdomen, but she had a red rocket that couldn't help but be firm and erect, given the situation; watching as Celestia's own member began to grow out from its sheath.
Loona’s cock was a good nineteen inches long, and could just about touch her tits, should it be laying down erect as it was. All in all, it was as thick as her forearm with the knot being as wide around as her upper arm. Loona was primarily hard because of the situation, but also from looking at Celestia's own growing length. It was already a foot and a half long and still growing longer and harder, thick as a leg and pulsing with veins galore.
“H-holy shit,” was all Loona could say seeing it grow, her own, by comparison, pitiful length twitching hard as Hell; veins bulging, balls clenching as drool couldn't help but roll from her lips.
Celestia chuckled as she slowly began stroking her length. Her digits dragged over the prominent light pink member, caressing it delicately. Its throbs were audible in Loona’s ears, making her gulp in a swelling fear and desire cocktail that was hard to fight. That growing fear of the thing that made her reflexively want to pull away like it was gonna kill her or something. That burning lust, paradoxically so, made her cock twitch like it was being stroked by a loving, sensitive hand, and made her pussy’s lips quiver, shuddering and oozing her own fluids. Her body was fully ready for such a thing to do whatever it wished to her, no matter how much damage her instinctual fear was internally exclaiming it would cause.
”Oh sweet fuck, i-it's just not stopping. How much bigger can she go? Dear god, she'll kill me with that thing. There's no fucking way… w-wait, calm down Loona… s-she can't even fit something that big in you. It's just not possible.” Loonas thoughts raced as she tried to calm herself. Her logic tried to prevail.
Celestia's hand gripped the powerful throbbing length by its sheath just under the medial ring, caressing it with her pointer finger. The monster attached to her had finally halted its growth, as far as Loona could tell, to her great relief, a weight lifting from her chest and the fear it would just keep going finally ending. However, there was now a twenty-four inch monstrosity pulsing between a nine-foot-tall alicorn’s legs, ready to absolutely demolish her. So yeah, the weight of dread on her mind wasn't going anywhere.
“Ooh, that look in your eyes… Guess my cock stole all the fight out of you. And here I thought this could be fun,” purred Celestia coyly. She was a mare of her people and had no intention of letting what were obviously assassins bring harm to her or anyone else. As far as she was concerned, this was an interrogation, and if Loona’s spirit was already broken just from looking at her cock, this wasn't going to be any fun at all.
“I'm just shocked it's so small,” dared Loona. She still had some fight left in her, damn it, and if some pompous white asshole princess with a big ego thought she could just do this to her, th–
Loona’s thoughts came to a grinding halt as Celestia's magic dug into her asshole, spreading the poor pucker open six inches in every direction, making Loona’s pelvis strain as tears suddenly beaded in her eyes.
Forget being stabbed, shot, she’d even been tased in the dick; this was unbearable by comparison. Every one of her sensitive nerves were pulled apart from one another and it made her buck and writhe, a gasp escaping her throat, and then another. She couldn't even form a coherent word of insult.
Celestia simply climbed into bed above her head. Her shadow was cast over the hound, her asshole being released of its torment after the most agonizing minute of Loona’s life. It was hard to focus after that, looking up, panting and feeling the dread spiking once she saw what was happening.
Magic enveloped Celestia's length, curling over it and her balls as it grew. “I think it's time I shut your trap,” purred Celestia, magic gripping Loona’s jaws and holding them open. “Insulting your new owner’s size isn't the best way to earn my favor.” She forced Loona’s head back and slapped the bottom of her twitching, growing thing against the roof of her mouth, and against her sharp teeth.
Not a single flinch, not a puncture or cut; only a purr of lust. Loonas fangs might as well have been silicon as she tried to speak. “Fuhuk yuhooe.” It was kinda hard to talk when upside down and unable to move her mouth, and on top of that, having a horse cock about to push its way in.
Loona tried to take a deep breath and brace herself, but that only let in the hot, sweaty musk of Celestia's bitch breaker, a foul scent that burned her nose hairs and made her eyes water, cascading across her body’s nerves like a wildfire, making her shiver and twitch, gagging and coughing up what she could before the behemoth encountered its first issue.
For one, Celestia's cock before beginning had been as thick as her calf muscle. Now it was as thick as her thigh, and the flare was the size of a dinner plate as the bulbous cock head protruded outward, oozing out slimy, glue-like precum into Loona’s mouth, draining down her throat and over the sides of her jaw.
This thing should never fit. It had met Loona’s lower lip, resting there as three spells took effect; a breathing spell, meant for long, deep diving missions, a healing spell, and an elasticity spell, the last of which was on Celestia's cock, rather than on Loona’s body. Loona just panted and tried to breathe despite Celestia's musk, hoping the monarch would take the hint that her stupid hung cock wouldn't fit.
It began to fit. Loona’s eyes went wide and she tried very hard to clamp her jaws shut, but Celestia held them open despite that. Her cock began to go in. First, the flare bent down, dragging along the walls, roof and floor of Loona’s muzzle, kissing her throat hole and forcing into it. Her tongue was pinned to the floor of her mouth and her throat stretched painfully by the second.
The healing spell numbed the pain and fixed any real damage almost immediately as Loona simply endured it, realizing pretty quickly that she wasn't going to be granted a break from this anytime soon, and she might as well enjoy herself as best she could. Even as tears flowed from her eyes, it took leagues of concentration to simply breathe in musk-laden air, so thick it was like a fog.
That said, she’d be lying if she said this wasn't hot as hell on a few levels. Rape was one of her favorite kinks, and at least in this circumstance, her captor clearly cared enough that, however she was doing it, she had taken steps to help Loona handle the massive bitch breaker as it moved down her throat. The flare pressed against her collar bone as she twitched and shuddered, drooling on it as she felt herself becoming light-headed.
While yes, the breathing spell cast on her meant she could live without air, there was still a massive cock down her throat clogging her windpipe, the veiny beast scraping against her spinal column. Without air in her lungs, Loonas body was freaking out nonetheless. It felt like she was on fire as her eyes rolled back and watered hard, especially as Celestia’s flare forced past her collar bone into her chest.
As Celestia pushed further, Loona’s claws clutched the sheets, her eyes bulging a bit as she gasped around Celestia's girth, feeling her flare press against her heart and lungs through her stretched and abused esophagus. By the second, inches were descending into her as her lungs and heart pressed against her rib cage, the pulsing of her heart kept regular and “normal” by Celestia's magic, even as her hot, steaming cock throbbed so hard that it drowned out the beats.
This feeling against her lungs made her only able to gasp and moan, out of air and twitching. Still, she forced her head along Celestia's length herself, licking over what she could, just to do something, rather than just lay there and be impaled on cock. That would be no fun for either of them.
Loona winced as Celestia's flare dug into her liver and curved down her esophagus, forcing into her stomach proper. With a particularly hard thrust, she slammed down into it, causing Loona to dig her claws into the mattress.
“Hreeheeghh!!” was all Loona could manage to gargle out around Celestia's cock in response.
The monarch purred, shoving one of Loona’s kidneys aside and between her intestines, stretching her stomach like a condom over her cock as she just kept going from there. The push forced her guest’s stomach to straighten out as she pressed deeper and stirred up her intestines. Loona’s entire torso bulged out with the detailed shape of her cock as she bottomed out, with Loona’s lips kissing Celestia's medial ring and sheath.
After sitting for a moment and letting Loona adjust to the insane situation to some level, Celestia began pulling back, with Loona’s lips dragging along the veiny member and leaving black streaks of lipstick from a smeared mark at her medial ring.
At the very least, it eased the pressure as Celestia pulled back. The bulge receded through all of Loonas torso ‘til her flare brushed against the sides of her breasts. Celestia roughly began pushing forward again, entering a tad quicker than she initially had. This sent Loona’s body quivering as she bottomed out once more and receded again, beginning to gently fuck the hound with a cock that put most dragons to shame.
“Mhmm~ Gosh, I haven't had a chance to have some fun with another being, let alone one as exotic as you, in a long time~” purred out Celestia, resting her hand on Loona’s throat as her magic let up off her wrists and heels. Her hands immediately grasped the massive bulge through her body as Celestia caressed her throat and choked her, in effect fucking her hand through Loona’s poor throat. “You’re gonna look very cute with a belly full of my jizz~”
Full was going to be an understatement with how massive Celestia's balls were, and Loona was all too well aware of that. But hey, she’d been able to, at the very least, handle this massive cock inside her. What was one load? It wouldn't be too much, right?
Either way, that was a question for later, as Celestia began bucking harder, something Loona immediately felt in the flare dragging across her ribs, making her jerk and cough out a whining gasp around Celestia's girth. Her eyes and ears twitched as she shuddered through the experience.
Her ears were assaulted by the, at this point, constant, rhythmic creaking of the bed at every one of Celestia's increasingly brutal thrusts. It felt like the sun’s gravity was hammering her insides. It hurt like Hell, but felt so so good. Whether it was the healing spell pulling all of Loona’s energy to repair the damage or maybe she was just a deprived bitch, Loona was starting to feel lightheaded. Either way, Celestia hammered away, lightly biting her lip.
Loona’s claws came up and grabbed the monarch’s ass. This wasn't something either was expecting, nor was the sudden slam to the depths of her cock.
Loona was debatably biting off more than she could chew, but Hell would freeze over before she was relegated to being the sub of a horse. Digging her lips into Celestia's crotch and inhaling her potent musk, it became hard to think. Loona just relied on instinct, pulling her feet along the bed and kicking up off of it with all her strength.
To say the least, Celestia wasn't ready to be slammed down on her backside with her muzzle kissing Loona’s dripping snatch. Those lips, a sore red color and quivering with desire between her soaked thighs, rested on Celestia’s face as Loona pulled up from her length with a hard gasp.
“F-fucking Lucifer! Could’a used a warning!” Loona barked after a coughing fit.
Celestia's magic grabbed her cock and Loona’s head, slamming the hellhound right back down on the pulsing monster, so stained with sweat, drool and black lipstick.
Loona’s cheeks bulged out. Her eyes clenched, she just about threw up, her claws dug back into the mattress and Loona slammed her hips down and came hard, feeling Celestia's magic spread her cunt wide by more than a few inches. Celestia's whole muzzle fit into the quivering hole as it gushed around the solar monarch, her tongue lickign and kissing at the hellhound’s cervix.
“Fucking damn this horse!!” Loona thought to herself as Celestia started brutally slamming her hips up into her several times each second, punching Loonas guts, lungs, heart and ribs; mostly her guts. She even slammed against the poor dog’s womb, bladder and pelvis.
Loona’s body was on fire, but she managed to pull her hands together and grip Celestia's balls tightly, making the alicorn’s muzzle open wide in a hard gasp, stretching Loona’s walls even more.
And yet, she didn't relent, digging her claws into Celestia’s balls. Not that they did anything to her beyond hurt, but Celestia was used to a bit of pain. After all, she’d pegged Tirek, and made an absolute bimbo out of Chrysalis through a month and a half of nonstop sex. This was nothing compared to what they tried to do to her and what she’d successfully done to them.
After several minutes of rutting, Celstias tongue lashing around in Loona’s depths and Loona taking quick short thrust after quick spit-throwing thrust, the door opened to the scene.
Luna looked Loona in the eyes, but the hellhound was busy having huge white nuts slap against her face as she clawed at the bed, ruining the sheets and mattress. “I can see you two are having fun~”
Loona wheezed and coughed around Celestia's girth, her eyes red and sore-looking from her lack of air. Luna watched her sister’s ever more erratic thrusts, knowing what was about to happen. Loona, the virgin in such an overwhelming circumstance, had no real way of realizing what was coming until it simply happened, and it happened hard.
Celestia's magic held her head down hard as she slammed deep into her, making sure to go every single inch as deep as she could. Her legs even lifted and crossed behind Loona’s head, holding her down on her shaft in a headlock as her magic glowed around her balls. Her sun cutie mark glowed as her nuts clenched and the torrent began its assaulting tsunami into Loona.
The meat pipe in her meant that she wouldn't taste the salty, addictive nut slop of the sun, at least not for a bit. It traveled fast, bulging out Celestia's urethra as Loona’s esophagus reflexively clenched tight. This only made the experience all the more intense for both of them. The urethral bulge grew visibly along the already existing detailed silhouette inside Loona’s throat.
It rushed through her and erupted into Loona’s stretched, beyond displaced stomach, filling it with pints, then bottles, liters, gallons of jizz were being pumped into her. Once her stomach reached capacity, the flooding torrent was too fast for it to flood other places before expanding, and Loona’s gut began to bloat with hot, slimy jizz. Her intestines began to fill as cum rose up her esophagus and spilled out around Celestia's monster.
The torrent of slimy nut slop erupted out of Loona’s throat into her mouth, letting her taste the thick-as-glue nut cream coming from inside of her. It made her want to puke, but that was a bit hard to do, given the circumstances. It forced up her sinuses, gushing out her lips and nose, making her exhausted face look all the more delectably hot. Her twitching eyes rolled back and she soaked Celestia's balls in her own thick seed as steam rose off of it.
Luna could almost swear that the hellhound was crying her sister’s seed, but what wasn't up for interpretation was the fact that cum had found its way into the hounds head and out her ears, soaking her brain in jizz as it spurted out of every orifice.
Meanwhile, Celestia was still pumping. Her load traveled through Loona’s intestines like a crashing tsunami, painting her insides white, so sticky that it’d be a part of her forever. It found its way to her bowels, crashing through everything and against all of her insides.
Celestia closed her eyes and hooked Loona’s asshole in her magic, lifting the dog up and opening her pussy juice-stained muzzle just in time for the leg-quivering torrent of jizz to gush and spurt from Loona’s quivering asshole.
Cum lathered and soaked Celestia's face, steaming hot as it landed on her eyelids, in her flowing hair, and especially her mouth. Her tongue was doing its absolute best to both collect her own jizz and Loona’s as her magic bent back the hound’s own cumming cock. It was just so much less by comparison that it was hard to even justify focusing on.
Luna couldn't help but stroke her own length, watching the lewd scene as cum erupted and flowed from both ends of Loona. Her bloated belly squished against Celestia's, sagging over her sides and touching the bed.
Celestia’s legs would eventually move after what felt like forever, letting Loona raise her head. She felt Celestia's huge length pull through her, snagging the powerful flare at the entrance of her esophagus and yanking herself up hard. She choked and gasped and quivered, unable to make much more progress as her throat spasmed and her lungs burned.
Thankfully, Luna’s magic grabbed her hair and yanked her off of Celestia completely, only to flop her on her backside and turn her legs toward herself. Cum bubbled up Loona’s throat as she coughed it up. Luna pressed down on her guts to force the chunky slime out as she wheezed and hacked weakly.
“G-good f-fuck, too much! H-how the fuck…?” Loona wheezed out.
Celestia simply stroked her cock and kissed the back of Loona’s head. “That was a small load.”
That comment drew an audible whimper from the hellhound as her ears folded back. Luna climbed into the bed, wrapping her arms around Loona as she laid on her side, the princess’s scepter pressed between Loona’s thighs and against her holes. Each slight grind from either of them pressed and dragged the sensitive dark flesh against Loona’s soft fur and her soaked holes.
The cum, seeping like white hot lava from her gaping asshole, covered and lubed Luna’s length, making it throb at the warm wetness as she rubbed the seed into both of their furs and crotches. A sticky mess of cum strings and sweat quickly formed between them.
As Luna began to thrust and grind, the alicorn’s flare would drag along Loona’s pussy’s lips, pressing partly into her, stretching her walls, and then sharply forcing out before pulling back and doing the whole thing all over again. Loona’s only solace was that this one was a decent few inches smaller then her sister, who she could still feel the effects of being speared by.
“I suppose that after you have your fun, dear sister, you'll join me to finish discussions and decide what we’ll do with the assassins?” asked Celestia, ever-so-casually.
Luna groped Loona’s tits, squeezing the soft furry orbs in her hands. She pulled her hips back to press her cock into Loona’s gaping rear. A burning sensation of pain and pleasure shuddered through Loona as she twitched and briefly grit her teeth.
“That sounds like a plan, dear sister. Do be warned, though, this session could last this entire lunar cycle. If you wish to come back for some fun, you’re more than welcome to.”
“Oh, such a mischievous one, aren't you?” smirked Celestia. “Are you sure she can handle more than a month of abuse like that?”
There were hints of lewd lust in the question as Loona listened in, despite the slow thrusts plunging up into her cum-slickened guts and setting her body on fire. At least the jizz tsunami had stretched her pretty thoroughly to prepare her for something like this, along with Celestia's ludicrous size.
That said, Celsetia was clearly a decent bit concerned that Loona wouldn't be able to handle the remaining lunar cycle. Twenty-four days, four hours and thirty-two minutes, roughly speaking, as the cycle had only started a few days prior.
“She's a hardy and strong girl; I can tell that much just from how tightly her asshole’s clenching on my length and the adorable noises she's trying to suppress,” teased Luna, tugging and rubbing the hellhound’s nipples. Her slower, almost comforting thrusts dragged along the walls of Loona’s insides and plunged back up into them.
“Very well, my dear Luna. Don't ruin the poor girl; I've already put her through quite the ringer.” Celestia strutted out the door. With a quick glow of the horn, her cock stopped being hard in an instant. The doors slammed behind her, leaving the two alone.
“Don't worry,” Luna reassured. “I'm not quite as rough as my sister’s blazing heat.” She’d also said that theyd be going for twenty-four fucking days, so Loona of course took that with a grain of salt and steadied her nerves, wiping semen from her lip with a cough.
“Alright,“ she panted out as Luna continued to toy with her breast and at this point start a good rhythmic thrusting up into Loona’s asshole.
“F-fuck horse cock’s good but… nyghh~ I- Let me ride it!” she gasped out.
This drew a lustful grin from Luna. She pulled out with a slow draw and tug of Loona’s asshole as her flare audibly popped free, well-lubed by her sister’s hot seed.
Loona took the moment’s rest in stride, gasping as she rolled onto her back and rubbed her bloated gut before mustering the strength to climb up to her knees and sit on Luna’s chest. Her own cock slapped firmly between Luna’s tits as she grinded briefly between the two fleshy orbs, even caressing one of the dark blue melons and pinching Luna’s nipple.
Loona did say she was going to ride though, not just play with the monarch’s tits. She lifted her seed-oozing ass up and Luna held her cock in her magic as Loona began to ease down onto it.
Her asshole was on fire from everything and her cunt was in desperate need, so it wasn’t a tough choice. Feeling the princess’s flare rub against her pussy’s lips and divide the flesh, digging the dripping urethra between them and spurting lightly into her, she knew she’d made the right decision.
She grabbed the headboard, grit her teeth and began to ease down, feeling it spread her lips, stretching her as tears watered in her eyes. She hissed out a light growl, gradually feeling the beastly thing's flare drag closer to her pelvis and even force past it as her lips quivered around the whole thing.
“A-ahh!~ f-fu~ hyghh!~ f-fucking go in!” She almost growled the command despite her shuddering tone and quivering body. She slammed her hips down, immediately crossing her eyes and gritting her teeth as her sensitive cervix was slammed into by Luna’s battering ram. Her womb was crushed behind it, seed spurting into the unprotected pup factory as Luna grabbed the hellhound’s thighs.
Luna’s cock wasn't even fully inside of Loona’s quivering depths, but it’d bottomed out more than most cocks would. “You want me balls deep?” purred out Luna, already knowing the answer as she grinded into Loonas womb.
“F-fuck, yes! Put a l–” Loona stopped herself, choking back her words. Horny as she was, she wasn't about to beg a random stranger to get her pregnant, was she? She was really hooked on horse dick. It wasn't too surprising, though.
Loona didn't have long to think on the idea of getting pregnant, which she realized was a very likely outcome of this, before her hips were slammed down, clapping against Luna’s. “F-fuck!” was all she could curse out as she grit her teeth and dug her claws into the headboard.
Luna’s cock was buried in her womb, wearing it like a condom around her length as it pushed her organs around, shoving aside her cum-bloated stomach and stuffed intestines, bulging out her torso so far that her tip was pressing against Loona’s breast through her, despite the sagging cum gut she had.
“A-ah! No… N-no way you’re the gentle one! A-ahh~” panted out Loona as the hellhound’s paws quivered. She started riding in rough sync with Luna’s thrusts, slowly settling into the rhythm of the fucking and enjoying herself. Despite her remark, this definitely was way more bearable than the totem pole between Celestia's legs.
That said, it did remove a bit of the thrill from it. Just a tiny bit, as no matter how you sliced it, a cock so big that its bulge was hitting your tits with every thrust, making your body quiver and titties jiggle could never become stale or boring.
Eventually, as the rhythmic bed-creaking continued along, Loona would grow comfortable enough to stop holding the headboard, simply bouncing up and down with each thrust. She brushed her hair back, wiping sweat from her brow in the process, and panted out in delight. Both had been silent for several minutes of pure, hard mating by this point.
Luna’s cock twitched and pulsed in Loona’s quivering and clenching cock socket. “Mhmm~ fuck, I'm glad sun-dick didn't try to fuck my pussy. I think she’d have killed me,” Loona panted, leaning back, resting her eyes and letting Luna do the work.
“She can be quite vicious,”Luna replied. “It’s easier with each load she dumps into you. I'm sorry to say it's quite the opposite for me.”
Slapping Loona’s ass hard, she jumped several steps ahead in a burst of speed; a very, very long burst of repeated organ-punching, short, strong thrusts that made Loona crumple against the headboard. Her jiggling tits hovered over Luna’s face as she panted. Her eyes twitched. Attempts at words came out as a slurry of brutal pleasured moans and pants.
“Wleagh hee h-h oohh~ I- uyghinm~ f-fuyhh~” Loona was a mess for the next half hour. Where Celestia seemed perfectly happy to bust a nut inside her whenever she wanted, Luna was just going and going and going. Sure, she was oozing seed constantly, but she just wouldn’t cum.
“P-please g-give… A-ahh~ Gimme i- f-fu-fucking cum~ P-put some babies in me!!”
Loona was full-on begging as she weakly quivered, enduring hammering thrusts at her depths. Luna’s flare scraped and dragged along her insides, and in this sweaty, lewd mess of futas, all she could think about was Luna cuming, putting a damn liter in her.
The thought’d been strong enough that another of many loads spurted from her cock and quivering pussy’s folds, soaking Luna’s tits and lubing her cock further.
“What do you say, pup?” teased Luna.
“Please… p-pwease, m-mistress… Cum inside me!!~”
Honestly, who could resist complying with that? She’d even said “pwease.”
In an instant, Luna slammed the hellhound down into the missionary position and began hammering away at her. Every thrust made her legs quiver and her ribs flex.
“Mhmm~ I'll make sure you have a nice litter of brats to rival any from the land you herald from,” toyed Luna as her cock throbbed and pulsed erratically. Her nuts clenched as her torrent of seed began, her cock burning with sensitivity as her flare spread out Loona’s depths. Sticky nut milk, somehow even thicker than Celestia's, erupted into her ovaries, sperm writhing into eggs the second her body released them.
Perhaps against her better judgment, Luna cast a spell to stop all of Loona’s eggs from forming their protective coatings meant to form after a single sperm enters them, leaving them defenseless from the countless other royal sperm. They ripped into her eggs like torpedoes, gangbanging her and filling her bloating womb. Her uterus stretched, pushing aside her sore organs to inflate just like them. Her belly, already looking pregnant, began to swell and swell as her claws ripped up the bedsheets, howls and gasps escaping Loona’s throat.
“F-fyack!!~ f-fuochhhe!~ m-mwaore!!~”
She practically demanded more and, damn it, Luna was too generous to refuse the debatably insane-acting hellhound. With another spell, she pulled a page from Celestia’s spellbook. Her cock, and more importantly, her load, grew as the length pushed up between Loona’s bouncing tits. With each hard slam, cum erupted relentlessly into her bloating ovaries and guts as Celestia's healing magic kept the poor girl together.
Loona, though mentally a mess, knew this would be the best month of her life even if it broke her.
Loona walked through the portal a month later in complete dishevelment. Her hanging gut and tits were clad in nothing but one of Luna’s bathrobes.
She held Blitzo back from ripping apart the ladies that put a truly massive litter into her that their spells weren't able to evaluate the size of this early into her pregnancy. She looked nine months along during her first trimester, if that was anything to go off of.
Needless to say, that would be a fun conversation to have when they all arrived back home. Almost as much fun as fighting the guy that hired them; an ugly yeti thing calling himself “The Storm King,” after he tried to kill them for not doing the job.
But those were stories for another day, just the same as the several days of sex that had left Loona so sore that even having two days of rest, she still needed more. That was gonna be hard with Luna and Celestia's lengths on her mind, making her loins burn.
