It's said that during the shortest night of the year, Equestria is closest to other planes of existence. Sunburst conjures more than he bargained for, but attempts to bargain all the same.

The Summer Sun celebration is one of Equestria's most beloved and widely celebrated holidays, serving to commemorate Celestia's salvation of the nation as well as marking the summer solstice. However, the solstice holds another meaning for practitioners of spellcraft across the land: it is said that for the short duration of that one night, the world is closest to the other planes of existence, allowing conjurers of talent to draw beings across the pale to study or bind in service.

Sunburst is not a talented conjurer. However, having whiled away his time at Celestia's School for Gifted Unicorns without managing to distinguish himself to another institution or a patron, this could be his final chance to prove himself before his final year is up. Utilizing an ancient site of unicorn power with his own experimental summoning array, though, yields results far beyond his expectations. For the first time in generations, a succubus is drawn into Equestria.

This piece of plot-light smut-heavy fiction was written for Lux Tenebris, for the Summer Sin 2021 story exchange! Lux has a couple stories with some similar themes and content, as well as some longer format plot driven stories too, if you'd like to check them out.

Sunburst sighed to himself as he heard the muffled crack-pop of what must be yet another sparkling, colourful barrage of summertime merriment in the distance. The Summer Sun Celebration might have been the shortest night of the year, but it did its damndest to make up for it by being the loudest. Especially in Canterlot.

It wasn’t that Sunburst didn’t like the holiday. Although he rarely got invited to attend with someone, the festivities were open to all, and the yearly celebration had for years been one of the few much-needed reprieves from his endless cycle of in-depth study, and failed application. If anything, it was disappointing that rather than joining the festivities under the moonlight, he was instead descending into the dark on these poorly-kept stairs in one of the less-visited wings of the School for Gifted Unicorns.

No.

He shook his head, ridding his spectacled vision of his ever-frazzled vermillion mane. Tonight, he had more important things to do. His hooves found the bottom of the staircase, and he looked at the rough-cut stone that was so different from the normal tiles used in the school. The door in front of him had never been locked when he first found it, so he figured it must have been allowed for a student to come down here. For him to enter the labyrinthine under-tunnels that ran beneath Canterlot.

The first time he’d descended into the dark, subterranean passages, he’d been terrified. Only his intellectual curiosity had spurred him on. Now, having made this curious trip many times, the novelty had long since been lost. The ancient unicorns who had cut these passages did so in an orderly, measured manner in their hunt for crystals for ornamentation and spellcraft. All one had to do was recognise the pattern.

Sunburst was good with patterns.

His interest in the tunnels wasn’t chiefly historical, however. In his studies, he had uncovered any number of curiosities the once-users and denizens of this network had left. Most were merely interesting, but the one he was making for now had real applications. Especially tonight.

He paused as the path suddenly widened into a pony-made cavern. It had a domed ceiling perfectly carved from the crystalline walls surrounding them, and no entrance but the path he came along. One less studied on the history of the unicorns who had lived here generations ago could easily dismiss the space as an unimportant room, one inconsequential dead-end among many. Sunburst knew the place for what it was. Although the smooth walls and ceiling were no long polished to a reflective sheen as they once would have been, the structure still functioned: it was a resonance chamber, meant for trapping and amplifying magic cast within.

He had set up his materials in advance of the Summer Sun Celebration and was glad to see they hadn’t been disturbed. The intricate geometric patterns he’d painstakingly marked out on the floor with magically infused charcoal was still in place to the line, circle, and rune. It had taken him a month to memorize the formations so he could mark them out without mistakenly disturbing one line with another. Then it had taken another two to figure out how to plausibly modify it to his needs. His changes to the arcane circle should feed additional power to its aim: reaching through to the next plane and pulling from it a being not native to this world. Normally that change would destabilize the formation, but that was where the resonating chamber came in. He knew the ancient unicorn architecture would keep it stable.

Theoretically, anyway.

He tried not to let that familiar doubt take root as he took the time to light the four candles marking the cardinal directions at the corners of the summoning circle. The thought that unicorns generations upon generations ago had performed this exact step hundreds if not thousands of times in this chamber gave him a strange sense of peace.

With the candles lit, though, came the final and most difficult step. His horn shimmered with golden magic as he began to channel it into the carefully arranged array. The magically infused geometry and runes began to glow in that same colour as they absorbed it like a reservoir. Normally, it would take much more time and effort, possibly necessitating a group of unicorns working in tandem.

The final aspect of his thoroughly-studied plan came in here. It was widely understood that during the summer solstice, their world would be at its closest to the neighbouring plane. With enough magic, one could reach deep and far in search of a being to conjure into the world. Again, theoretically, this should mean it would require less magic to reach into shallower depths. All he needed to prove the efficacy of his theory, of his formation, and the importance of the ancient unicorn chamber it was arrayed in was to grasp even a lesser spirit and draw it into this world. That would be enough to garner the attention of at least an advanced institution. Perhaps it would even garner the attention of a patron in Canterlot with a special interest in summoning magic!

Then, all his restless nights of studies would be worth it.

The faith of his mother would not be misplaced, and she could stop bothering him about his direction in life now that he was a stallion.

He gave a small gasp as the arcane circle reached maximum charge, glimmering momentarily, beautifully sunlight-yellow, filling the room with its glow. Surely, this beat out any of the fireworks that would have been on display in the city streets.

He focused his magic towards the center, finding a sensation like resistance. Then, he pushed, focusing narrower and narrower, and those innermost runes seemed to fold around the distorting space, at once empowering and stabilizing the growing opening between worlds.

“Agh!” Sunburst shouted as, with a crash and pop, a sun-bright flash filled the chamber for a split second. Had he failed after everything? After so much effort and so many lonely nights squinting at old texts in the dark? Even as his vision began to clear, it was already blurring again, the too-familiar hot sting of tears starting at the edge of his vision.

And yet, there was something at the center of his carefully crafted spell. A dark and solid shape, so it couldn’t be a wisp… Could it be an imp? But it seemed too large. Yet, it was so much smaller than the next most common monstrosity he might have snared in his spell.

As his vision finally resolved into the relative clearness his glasses afforded, Sunburst gawked at the silhouette standing in the madly flickering candlelight. It was of equine cast, with four legs and roughly the same proportions as a pony, but the similarities ended there, leaving the likeness uncanny rather than relieving. It had no coat, but instead a smooth black carapace, largely featureless except for a few segments around the midsection and neck. Each of its hooves was marred by irregular holes, and its ears were tattered where they stood off of its head. A pair of leathery wings, bat or dragon-like, flowed from its back, shimmering with an insectoid iridescence, while a pair of horns rose in elegant curves from its head. Its heart-shaped tail flicked as his eyes traced its slender length, only for him to raise his eyes and realise with a jump that its luminous purple eyes were studying him in return.

“For what have you summoned me, mortal?” she asked--as the creature’s voice left Sunburst little doubt that it was a she--with a silken confidence that suggested she already knew the answer. Sunburst found himself wishing he did, as well. He swallowed hard and immediately regretted it, as the creature flashed a smile full of brilliantly white fangs.

“I… That is… You’re…” Sunburst drew a deep breath and adjusted his glasses, as he often did in an attempt to clear his mind as well as his vision. He searched through the vast catalogue of knowledge he’d accrued in his time at the School for Gifted Unicorns. Far from the lesser spirit he’d attempted to conjure, what stood before him now appeared to be every bit as intelligent as a pony, and was aware of her circumstance. Sleek and predatory. The dark, feminine cast of its form. The way it waited and smiled, exuding hunger and lust. “... a succubus.”

She seemed puzzled by this reaction, and that terrible smile faltered for a moment as she glanced at the array of geometric runes surrounding her. When she looked back up at him, though, the vicious grin was restored. Perhaps it was intended to be comforting, though, considering the patient tone with which she answered, “Precisely so, conjurer. Was it not you who summoned me?”

“Well, yes, but…” Sunburst trailed off, his mind racing. This should be impossible. Or at least extremely improbable. A succubus hadn’t been called up in Equestria for more than a millennia, and the last time one had, it had led to the fall of the western reaches of the kingdom, and the birth of the Changeling swarm. Anxiety coiled around his throat, and he couldn’t help but glance towards the creature, and then away again at her expectant look. This was terrible! She was catastrophically dangerous, and it was his fault she was here.

But what magical knowledge could be gleaned from a being so ancient and terrible, to say nothing of what it could mean for his career? Forget being picked up as a teacher for a magic school, with this kind of notoriety he could head his own magic school. Maybe his mother would even stop bothering him about finding a girlfriend. So far, the changeling-like creature had been docile, if not friendly, and if nothing else the runes of binding and sealing around her could contain her.

“Yes! It was I who summoned you,” he suddenly announced, with as much pomposity as he could summon. The succubus looked at him and an awkward beat passed, and he was left to wonder just how long he’d been lost in his own thoughts. He cleared his throat and pushed up his glasses, before lifting a hoof to run over the fine red-orange hairs on his chin, as he imagined the great wizards of the past must have. What was next? Right, an important step in communing with and exercising power over otherworldly beings of all types: “What is your name, erm, succubus?”

“Acrasia,” she replied, matter-of-factly. Sunburst was stunned for a moment by how easily and quickly she answered.

“Uh, er, really? Don’t I need to press you for it, or something? Maybe answer a riddle?” He blinked, and she blinked back. “I mean, that’s what I needed to do with all the… Other beings I’ve summoned.”

“So I see,” she answered, and she gave him another one of those terrifying, reassuring smiles that so nicely emphasized the points of her teeth. “I have long grown weary of such trite theatrics. No, I would sooner not waste more of my, and your, precious time. We both know well why you have summoned me, oh conjurer.” The hunger in those bright, intensely purple eyes made his coat crawl and his face heat up. They wandered over him like so fine a meal, leering at his orange and white coat stretched over his self-admittedly scrawny frame as if he were the only stallion in the world. He knew at once what she meant.

“Uh… Haha, actually, you see… I was hoping I could just ask you some questions? That is, I’m…” Sunburst’s mind fumbled momentarily as he watched Acrasia’s tongue run across the smooth dark lines of her lips. It was forked, and luminescent in a shade of purple a touch darker than her eyes. “... I’m interested only in… expanding my knowledge of the arcane.”

“Really?” It was the succubus’s turn to be surprised by this breach of cliche. All the same, after a moment’s thought, she continued on in as silky a voice as ever, “Very well, oh studious disciple of the arcane. I will share with you my knowledge.”

Despite the slight trembling in his legs, Sunburst smiled. Acrasia continued, “But, certainly a summoner of... your talents must know that to sustain a conjuration, a degree of energy must be expended to ground the summon?” She noticed Sunburst’s eyes flicking towards the arcane circle around her feet, and cut in before he could say anything. “The arcane energy expended in the summoning may be enough to sustain a mere wisp or imp for some time, but for one such as I? It might keep me for an hour at most.”

“Right,” Sunburst sighed. He certainly hadn’t been prepared for this possibility, and fell into a sullen silence as he realised this, his greatest magical accomplishment--and indeed among the greatest magical accomplishments in Equestria for the past few hundred years--may fizzle out like a weak flame.

The unicorn once more flipped through the deep encyclopedia that was his mind for an answer, but one was quickly presented in smooth, sultry tones. “It would be so easy a thing, clever magician. I merely need from you the sustenance my kind craves, that we need…”

“Oh. You mean…” the young stallion cleared his throat, his ears burning, and he looked at his hooves lest he look into that voracious purple gaze.

“Do you find my appearance so displeasing?” The disappointment in Acrasia’s voice forced him to look at her.

“What? No, no, I…” His eyes roamed her form momentarily. She was strange, monstrous even, but to call her displeasing also didn’t do. He tracked the slender, feminine flow of her body, thin at the middle before flaring dramatically out into wide, full hips which in turn fed into the shapely buttocks he could only see a hint of given her current stance. Her face, too, was unworldly but undeniably pretty--no, beautiful, with a slender muzzle and deep black lips that made her perfectly white teeth show that much more vividly. “I’ve… Just never… You know…”

“Is that all?” Acrasia answered almost too quickly, and too kindly.

“Well… And, ahem, I suppose the teeth are a bit much.”

“Would it please you for me to change my form?” The creature leaned a bit closer, those large eyes lidding, just-so. “Tell me about a mare you like. Or, a stallion?”

It took him a bit of searching to settle on the answer to that. His struggling studies had left him little time to get to know his fellow students. But there was one, who always seemed to go out of her way to talk a moment to talk to him when she passed, and who invited him to events and parties no matter how many times he’d turned her down. Sometimes when he was lonely and aroused, he would remember her smiling face.

He started to describe her slowly, although he struggled to maintain his description as Acrasia changed shape bit by bit. Smooth chitin turned a creamy white before the coat grew out. She blinked and her eyes showed like a pony’s in glimmering turquoise. Her mane grew as hair filled out her tail, both curly and pink. The cutie mark she now bore showed a trio of blue stars.

The likeness she bore to Twinkleshine was incredible given the vagueness of his description, albeit with the goddess-like body of a succubus and pair of black horns arching above her head. She gave him a pretty smile. Without the shock of those predatory fangs, his heart raced for different reasons, and pulsed harder in different regions.

"This is better?" the succubus slowly asked with a swish of her new tail, and he nodded. "Good. Now come closer, into the circle, and let’s get comfortable, shall we?"

"Into the circle?" Sunburst echoed, and he gave the ring of arcane symbols a glance. He knew it was dangerous to cross the magical boundary that sealed a conjured entity, yet the succubus had been nothing but amiable so far, and with the face of his schoolboy crush, she only seemed all the less intimidating. She had more to lose than gain by lashing out at this point, having already given her name, and he could always call on the safety spells to bind and then banish her.

He stepped nearer, to Acrasia’s clear pleasure, his hoof-falls loud in the still underground chamber. Sunburst paused as he neared her, and began to say, “Alright. Now wh--” before he was abruptly cut off by the taste and heat of Twinkleshine’s--no, Acrasia’s lips on his own. He gasped at the suddenness and aggression of the act. She smelled sweet. Not like a flower or a pastry, but something much more intangible and alluring. He would have to note that in his study.

Any intellectual thoughts were suddenly derailed as he felt his balance suddenly stolen, a flash of magic from the succubus’s horns suddenly lifting and shoving him onto his back. Terror suddenly gripped him as he was rendered into as vulnerable a position as a pony was likely to find themself, his body tensing and trembling as his own conjuration bore down on him. Rather than the sudden piercing and tearing of fangs, though, her lips found his own again. That plush heat pressed to him hungrily, and even as his heart still raced in fright, his own lips pursed and started to kiss her back, clumsily but earnestly.

Her forelegs pressed at the sides of his neck, and his lips momentarily parted from her own with a rasped, “Oh!” as he felt her undercarriage press against his own. The warmth of her fur pressed and slid against his already mostly-erect length, and she shallowly rubbed herself back and forth against him, quickly coaxing him to his full size. Even when she had, she didn’t stop, continuing to grind against him as she deepened their kiss. The brief opening of his lips was taken as an invitation, and with a twist of her head, she locked their muzzles together, knocking his glasses askew.

He felt her tongue press past his lips. Despite her transformation, it was still slender and forked, and it triggered a squirming anxiety in the stallion’s stomach. All the same, as it pressed and stroked against his own tongue, he found himself sucking on it and licking at it in return.

The simple sensation of that intimate, insistent kiss and the continuous push and rub and press of her warm fur and feminine form against him was overwhelming for the inexperienced male. Before he could even begin to grapple with the intensity of the moment, he could feel his pleasure suddenly spiraling higher and higher, beyond his control. He trembled against the succubus, his legs kicking the air as he attempted to buck, but he was only able to awkwardly rub himself back against her. His head spun as he peaked, sudden and hard, feeling the heat of his own seed on his fur before he crashed, and his form went limp. The creature wearing Twinkleshine’s face didn’t seem discouraged, continuing to kiss him and tongue his mouth, and rubbing their bodies together in an increasingly messy fashion, until he finally groaned, spent and overstimulated.

At this, she drew back, giving him one more kiss on the lips as he attempted to sort his spinning, blurry vision. Finally reaching out with his magic to push his glasses back up over his eyes, he found Acrasia smiling down at him. Somehow, her equine facade barely did a thing to conceal the predatory intent behind the expression.

“So soon, my clever morsel?” her voice came, low and sensual and just a touch disappointed.

“S-Sorry, I… I’ve never…” Sunburst was surprised by how out of breath he was.

“Now now, no apologies--this time,” her lovely smile loomed, threatening, like a beautiful dagger. “But you would be wise not to risk wasting your essence next time. Be still now, lest you worsen the situation.”

She moved before he could speak--or more likely, ask--more, lowering her muzzle to his neck and beginning to slowly descend his form, rubbing his still oversensitive length to her short fur as she went. As she neared his chest, he gasped at the sensation of that long tongue pressing in against his fur. In long, hot brushes it traveled along the orange field of his coat, moving not right to its objective but meandering, vivid and sensual lower and lower, leaving quickly cooling saliva in its wake. Finally, he could see her muzzle reaching the first sticky patches of his fur, and there she lingered, that long tongue thoroughly licking up his spent ejaculate to the precious drop.

“Wow…” he moaned softly at the erotic mixture of sensations, and at the sight of her so diligently cleaning him. She tongued the head of his member for good measure, gathering up the last few drops there, before lifting her head again.

“Mmmmh… While your endurance lacks, you are all the same most potent. Yes, you will do nicely,” the succubus cooed. From this position, with her forelegs bent low and her back following up into her raised rear half, he could swear she looked all the larger and more shapely.

“Haaa, ah… Thanks, I guess?” he replied, having to pry his eyes away from the luscious silhouette of her ass to find her face again. “Wait, do nicely for… what exactly?”

“For restoring my strength of course, sweet treat,” she answered him easily. “Then, I shall impart on you the knowledge that you seek.”

“Oh… I... Don’t really recall agreeing to exactly that,” Sunburst replied, still out of breath, but with his head momentarily cleared of the thick fog of pleasure and attraction. “Just that I’d sustain you long enough to learn from you. Maybe after I’ve got an idea of what secrets you possess, we could discuss more?… And, aha, anyway, whew, I think I’m done for a while anyway.”

Despite his best attempts to remain affable even turning down the conjured being’s demand, he could see a clear tension growing in her form. Somehow, the vivid displeasure on her face seemed even more unsettling when signaled by his schoolmate’s normally cheerful face.

Acrasia smiled after a moment, though there was a cold sharpness in those pretty turquoise eyes. “Done so soon?” the succubus spoke. “Yet your body seems more than eager to continue.” Her horns glowed not the blue of the one that possessed her borrowed features, but the deep, devilish purple of her eyes and tongue.

He gave a start as he felt her taking hold of him again, and attempted to roll back over, but her front hooves pressed at his sides, her forelegs bending around his legs to lock him in place. That glow enveloped his stallionhood, lifting it away from his body to aim roughly at her face, and he realised then that he was already hard again. That masculine flesh twitched a bit in time with his quickening pulse.

“And you still have so much yet to give.” The creature’s monstrous tongue touched him again, its slick heat this time coiling around his balls. It practically slithered in its motions, constricting those soft orbs with surprising delicateness--after all, their contents were precious.

“Huh, hold on, I, uhh…” Sunburst again found his focus clouded, not by the loss of his glasses, but by an even heavier swell of lust and arousal than previous. His entire body trembled and tensed as she guided her tongue, pressing and squeezing up the length of his erect cock to its head. Suddenly, he was engulfed in the pressing hot and wet of her mouth. The succubus gave a single, long and intense suck around his crown, and he responded with a single shallow buck as what might have been a small spurt of pre-ejaculate suddenly intensified into a single intense rope of his cum. It wasn’t a complete orgasm, but the suddenness with which it struck him left his eyes spinning.

Acrasia was all too happy to capitalize while he was stunned, those luscious lips sliding smoothly down his length, while that firm suction continued unabated. Just as Sunburst was beginning to recover, her lips met his lap and her eyes met his own, cold and cruel and confident. He realised without a beat that the crushingly tight, velvety vice currently strangling the last several inches of his cock could only be her throat. She gave him several long squeezes and his legs trembled, pleasure once more spiking, but this time he clenched as hard as he could manage, barely managing to hold out.

Had she always been this large? When he’d summoned her, he was sure she’d been almost perfectly at eye level with him. But, even bent as she between his hind legs, it felt like she was looming over her. Those protruding horns were longer, and her proportions fuller still. She really was getting more imposing and more powerful by the moment! Panic gripped him. If he didn’t do something, she would continue feeding from him until she was strong enough to overpower him and the wards keeping her in place.

“Ac… Acrasiaaauhhh…” Sunburst's voice quavered as his length twitched in the suffocating embrace of that demonic throat. The welling pleasure was overwhelming, and the incantation he was reaching for to activate the binding runes surrounding them slipped from the forefront of his mind in favour of the shaking orgasm she finally pulled for him with one last, terrible suck. Again his body rocked out of his control, and he could feel with near-painful intensity her successive swallows. In the relative silence of the room, each gulp seemed so loud. Nearly loud enough to overcome his heart pounding in his ears and his breath rasping on the sex-scented air.

Even as his eyes crossed and he fell limp amidst the arcane formations designed to seal and ward, he could feel her mouth and throat already working again. Forget the danger of her continuing to gain power, she was determined to drain him until he was a trembling husk!

“Acr--asia,” his voice was quiet even in his own ears, but he forged on with the last strength and resistance he could muster. “By… By your true name, I bind thee!” His arcane command was more of a wheeze at this point, but all the same, the succubus suddenly froze as the coiling symbols around her shone in the dim room. She strained against the arcane forces keeping her still violently enough that he could see her trembling--and what was more, could feel her neck violently wringing him--but she was stuck fast. Fury shone in those usually-kind blue eyes.

“By the, huuh, laws, celestial and lunar, I… I strip you of your powers--” Her changeling magic was stripped suddenly, revealing the monster beneath. Without the guise, she was truly imposing by now, if not terrifying. The span of her glinting leathery wings was larger than a griffon’s, and her horns towered and twisted over her head like a primeval crown. Her beauty, though, was not diminished. Her curvaceous body was a temple to fertility in itself, her facial features now fine enough to resemble a goddess relief chiseled from black marble. The breath was stolen from him at the wondrous, terrible sight: a dark and twisted likeness of an alicorn all clad in the black carapace armour of a changeling. A succubus in her true glory.

She suddenly threw her head back, releasing his length. The magic already struggling to contain her powerful form broke with a sound like glass chains being smashed. Her wings flared wide and furious, and she loomed over Sunburst as his lips moved through the final incantation, but no sound came forth. He shakily moved to roll and right himself, but one of those dark, twisted hooves suddenly pressed down on his chest, hard, pinning him and pushing the rest of the air from his lungs.

“Imbecile,” she hissed, her long, graceful neck bending to bring her face a bit closer to his own as she peered down into his eyes. “Was it not you who summoned me? Was it not you who entered this compact of your own will, seeking power? How fickle you are, mortal, to try to cast me out now, your pleasure taken.”

“No, I… I didn’t mean… You were…” Sunburst's lips tried to offer all of the possible excuses his brain could conjure at once.

“Cease your babbling.” She pressed down on his chest, pushing him roughly against the floor. “You are fortunate, my foolish morsel, that I am in a gracious mood, owing to your previous offerings… And the potential I have seen therein. Apologise--beg!--and I may forgive you yet, and allow you to continue serving me, with all the benefits, with all the knowledge and the pleasure and the power that comes with doing so.”

“I’m… I’m sorry…” With Acrasia’s powerful form and those intense, cruel eyes boring into his soul the words tumbled out without a second thought.

“I’m sorry--” the succubus prompted.

Sunburst had lived in Canterlot long enough to know what she was prompting him for, but not exactly what she wanted. He tried, “I’m sorry… mistress?..”

The edge of her hoof digging into his ribcage informed him this was not the desired title, and he groaned. Couldn’t she just tell him? No, judging by the dangerous, jagged grin she was watching him with, she was enjoying this. “I’m sorry, my lady?...” Another crushing step, but it was less intense than the last, or at least he thought so.

“I’m sorry my Queen!” He blurted as soon as it occurred to him. “I’m, I’m sorry… I was just afraid but please… Please let me serve you faithfully from now on.”

Acrasia eased the pressure on his underside and gave a brief laugh that echoed in the chamber. “See? You’re learning already.” That peculiar, hole-marked limb ran up his neck to stroke under his chin at the light tuft of hair growing there. It was a small but demeaning gesture, the sort of physical praise one might give a pet, and yet he felt blissfully thankful for it following her show of strength over him. “Now you shall perform your penance.”

“A-Anything,” he swallowed. “As you wish, my Queen…” All the fight had been throttled--or perhaps sucked--out of him by this point. What else could he do? He could attempt to teleport, perhaps, but with his concentration as shaky as it was, and her bonds all but undone, he was more afraid of how she would punish him again than he was of his current circumstance. The unicorn tried to convince the feral terror stampeding in his chest that his contract with the succubus, however informal it seemed, meant she wouldn’t harm him.

She suddenly shifted her position, rounding with a single graceful movement, and as she stepped over him her intent became perfectly clear. Even before she began to lower her hind half, he felt a single hot drop of demonic arousal hit his muzzle, sizable enough to leave a small splash over one of the lenses of his glasses, giving him a partial blindspot. However, he would hardly even need his glasses with the dark silhouette of that alicornesque ass descending around him, to say nothing of the sight of her sex.

The anatomy was roughly equivalent to a pony mare, possessing pretty folds tucked between a plush outer labia, leading logically down to a large, pronounced clit. The colour, though, was vibrant, a purple like her tongue flesh, following and fading through several different shades and intensity of bioluminescence as his eyes followed its contours. Her clitoris winked as it neared his face, glowing intensely for a moment. It pressed, humid and hot, against his muzzle as he found his head squeezed and pinned in the claustrophobic embrace of those dark thighs and that vast posterior.

“Come now, plaything. Do not keep me waiting,” her voice came, seemingly from somewhere distant. “Taste me… Immerse yourself. Lose yourself in your worship of me…”

The young stallion who had not so much as kissed a mare before tonight had no clue how to approach pleasing an ancient sex demon. Yet her words and that sweet scent, so much more intense now, coaxed him in. His tongue found her flesh, experimentally running up along one of her lips. She was hot to the touch, hotter than he’d been expecting, and her taste was not as sweet as she smelled but a subtler and stranger taste, almost floral with just a touch of spiciness that tickled his tongue. Whatever it was, though, it coaxed his appetite in a new and intense way. It stoked the familiar flame of lust that had been with him as he grew into a stallion to a new, overwhelming intensity, and after a few more exploratory licks he dove right in, burying his muzzle between the slick, soaked folds grinding against his face.

Acrasia’s laugh came again as she allowed her weight to settle back against the now-eager stallion’s pressing tongue and sucking lips. “Mmmh… You stallions are such admirably simple creatures. Give you a little taste of what you want, and you’ll pursue it relentlessly… Recklessly…”

A heated sigh escaped her lips. The magician’s technique--if it could be called that--was lacking, but now that he had submitted himself to his place beneath her, he was all the same earnest and energetic. Even as moments stretched to minutes, and in those minutes trapped between thighs and beneath ass oxygen must have dwindled, he didn’t struggle, only forging on, his mouth messily probing every inch it could reach. She ran the frog of her forehoof along the length of his cock, and it twitched vigorously at the slightest touch.

Without warning, Acrasia rose once more, and Sunburst gasped, deep and desperate. Dizzy and lightheaded from the lack of air, and with his glasses completely wetted and fogged from his extended stay buried in the demonic mound, he was only vaguely aware of where she moved away from him. It took him another minute or two to catch his breath enough to even start to move, but by then the swelling urgency between his legs had taken precedence over his other mental faculties. At long last he rolled onto his side, and then gradually found his footing, straightening up on shaky legs to look around for his Queen.

She wasn’t far. A mere few paces away, she’d lowered her imposing frame to rest on her front, with the brightly glowing petals of her sex painting a vivid and enticing target from behind. Her head was turned to look at him just so, and although she said not a word, the lust and hunger on those beautiful features told him exactly what was expected of him. Exactly what his purpose was.

A distant tiny corner of his mind reminded him he had found his footing at last. That there was space between them. That he could still call on his magic.

He stepped up behind his monarch, and without another thought slid his forelegs up over the swell of those fertile hips. Positioning himself was awkward, but instinct spurred him, and he shuffled closer. Despite her presenting herself to him, he knew all the way to the core of his being who was still in control. Her size, her posture, even the look in her eyes all spoke to her power. He felt that long, thin tail against the side of his neck, and then around it, squeezing but not constricting.

“Good, my treat,” she encouraged, her voice crackling with the heat of her lust. “Now, let us complete our compact. Claim what you so badly need, and I will claim from you in turn what I desire.”

Sunburst didn’t need to be told at this point. He pressed forward suddenly, those beautiful purple folds spreading before the thrust of his head and the shaft that followed. He groaned at once, suddenly engulfed in a heat unlike even the voracious demon’s gripping, sucking maw earlier. She was so wet, her interior so welcoming, that he hardly met an ounce of resistance before he felt his balls pressing up against her, and felt the bright beacon of her clit winking against them as he instinctually ground against that luscious posterior. His breath caught as he felt her suddenly squeeze down around him, her passage seeming to grip to conform to him, making the easy fit suddenly snug. His withdrawal, as such, was even more wonderful than that initial thrust, each inch of her walls gripping at his shaft, sucking around his corona.

Somehow, he held on for long enough to draw back far enough that he could thrust in again… And then again, and once more. Every thrust felt like it would be the last for sure, but he held fast. But, why? Was it not what his Queen wanted that he fill her, that he complete this final offering to her? Did he not wish to disappoint her with his stamina? Perhaps even impress her?

“That’s it,” Acrasia cooed to him, venomous, intoxicating. Sunburst could see her lips moving but her voice sounded far away, especially over the repeated, raucous impacts of his body to her own. “Give in… Lose yourself entirely. This is what you were made for, is it not?”

He struggled to find the breath to speak, but managed, “Yes--yes Queen.”

“Good!” The monster laughed, her long tongue running the length of her lips. “Rut yourself senseless--rut yourself raw! Give your Queen your everything, your very essence, and forget everything else. Come, restore me to the height of my power. Sire a thousand demons that I may again reign supreme!”

Coming through the haze of pleasure and lust that hung in a hot, humid curtain over the landscape of his mind, those words drew forth his small knowledge of the succubi, what they had done in the past, and what they were capable of. Even the constant gripping-squeezing-pulling of that heavenly, hellish pussy could not dissuade this thought once it had taken root. What would it mean for Equestria if he gave in now?

His pace suddenly slowed, and then stopped. “W-Wait… I… I can’t,” his voice trembled, as did his exhausted body. He attempted to draw away, but his forelegs just twitched as he tried to move them from their place on those wide, wide hips.

“Resisting, now? I’m impressed,” Acrasia replied, although she hardly sounded it as she watched the male weakly struggle to disentangle himself. “It is far too late, oh conjurer. Our contract is all but complete. All it will take is a touch… more… pressure.”

Sunburst’s eyes rolled and his vision spun as she suddenly squeezed around him, tighter even than before. His twitching member was already at its very limit, his aching balls already drawing taut. Every muscle of his body was tense in preparation for him to carry through with what instinct demanded. He could feel his sweat running down from his mane, and feel the demon’s own intensely warm fluids dripping down over his lap. “Nonono… I’ve… This is… Enough… Equestria… Can’t.”

“Oh, but I know you can,” the dread Queen answered. Those dextrous internal muscles twisted around him, and pulled, not all at once, but instead gradually sucking, pressing, sucking. She watched him closely, he knew, that terrifying razor grin of hers saying it all. She was amused to watch his every twitch, hear his every fading moan as he attempted to resist.

Finally, he gave. His voice cried out briefly in dismay, and then in bliss as pleasure overwhelmed even the terror of what his inevitable loss of self-control could mean. Pleasure spread from the messy point of contact between their forms out through his whole form. His face against her back as he could feel himself drooling openly against her, and even as he wheezed and shivered in exhaustion his hips renewed their motion on pure instinct, attempting to drive his seed deeper into his infernal mate. Even after he’d spent five ropes, and then ten, her damnable body kept relentlessness working him, pushing and pulling him far past the normal limits of a stallion. Yet all the while as his molten, pent cum flooded her more and more and more, not a single precious drop of that essence spilled.

Her own pleasure, her own triumph was announced only in a low moan and a flaring of those monstrous wings, and a look of utter satisfaction that spread over her imperious features. The sight of that monster beaming back at him so brightly, so terrifying and beautiful, as she relentlessly drained him was the last thing Sunburst could recall before his consciousness slipped away.

He certainly had been an interesting one. So compliant and manipulatable, yet maintaining some shred of resistance and self right up to the end. His endurance hadn’t been anything great, but he had plenty of essence to offer her. He had potential.

With her powers fully restored, it was a trifle for the towering succubus to blend in with the crowd. She was just another pastel face and mane among multitudes in the early-morning dark of Canterlot. Even after these hundreds of years, the equines still did love their garish festivals, didn’t they?

Colourful sparks shimmered from above, brighter than the stars or the moon, and some of the ponies around her gasped in awe. How awed would they be to see her, in all her splendor, she wondered? A thousand firework displays could never compare.

But now was not the time for that. There was much yet to be done before her full grandeur could be admired. Soon, the sun would rise over Canterlot, and by then she would be gone, off to distant corners to quietly begin her true ascent. To lay the groundwork of her conquest, of her Queendom.

She wondered where that young mage would be, then. Certainly, she would seek him out. After all, their compact had been fulfilled even to her satisfaction, and she had much more yet to teach him.
