Darkest Fate, Deepest Pleasure
Sombra held the last pastry to Twilight Sparkle’s mouth. She glared at the tantalizing pastry that wanted entry, but Twilight refused its admittance. But Sombra had the means to gain access.
He magically reached for the rod he had implanted into her marehood and pushed it deeper into her, igniting her pleasure centres. As it flared into her it became an unwanted moan.
He did not hesitate pushing the calorie rich pasty tight into her maw. The rich flavour stunned her tongue; the urge to chew was difficult to resist, and knowing what Sombra would do if she dared spit it out she whined in defeat and started chewing down the treat.
The please king warped his powerful arms around her bringing the mare closer to him, Twilight let her head rest onto his bare chest. She chewed it a few times before swallowing the pastry down her gullet and into her bloated stomach.
Sombra rub her stretch belly - rewarding her with another telekinetic push of the rod into her marehood - she let out another moan and Sombra just chuckled, tasting her conflicting emotions within her, “Very good, little one.”
Twilight wasn’t always a slave to Sombra. Before her imprisonment she was a simple studier of magic. Despite her failure to pass the test at Celestia’s school of gifted unicorns, she never lost her interest in magic and what she failed in magical ability she excelled in her knowledge of the arcane lore which earned her a Cutie mark of a singular star; A simple cutie mark for a simple unicorn. Her knowledge would have earned her some recognition, but her lack of magical talent and her low self-esteem, she decided to live a life as a simple librarian in a small village called Ponyville. The simple, peaceful and easy life, but all were in short supply in today’s Equestria.
Over the years the country has been assailed by villains of terrible power: Nightmare moon’s return, Discord’s escape from his stone prison, and the Changeling invasion. Fate was kind enough that all were defeated, but she couldn’t spare anything when it came to the cost of their destruction. Even with the Elements of Harmony, Celestia could only seal Nightmare moon away, inside the mind of her younger sister, Luna which the spirit had possessed so very long ago. However, she must now always wear the Elements or the nightmare will take her again.
Without the elements, Discord could roam almost unopposed. Luckily his own arrogance provided his own undoing as he fell for a trap that sealed him into the pits of Tartarus, alas, his chaotic magic still scars the landscape.
Then there was the changeling invasion in Canterlot, happening at the same time her brother Shining armour’s wedding too. They were beaten back, but not without most of City’s populace being taken, including her brother’s mare-to-be, Cadence.
When the disastrous year finally past, many had hoped that Equestria would’ve had time to lick its wounds and return to peaceful harmony.
Then the Crystal Empire returned, along with its Dark king, Sombra.
Sombra quickly took control of the empire and enslaved the minds of the crystal ponies that lived there. He used them to begin his conquest of Equestria, taking most of the northern territory with little opposition. It was in this invasion that Twilight decided to involve herself in the matters of Equestria, mainly in understanding Sombra’s magic. Her courage to do good was rewarded with her being captured during the siege of Staliongrad and being auctioned off as a slave in the crystal empire days later. It was how she met Sombra - just as she was being sold off - her purple eyes laid upon his own red ones. For whatever reason she caught the tyrant’s interest, and in a deep voice he shouted, “5,000 bits!” Triple the amount another buyer offered.
She was dragged into the crystal castle, she expected to be torture or used in some sacrificial ritual. Becoming a sex slave was down somewhere on her list of “expected fates” but she expected more cruelty, blood and pain. What “agony” she received was an expanded figure and the occasional sore holes. Not great, but it beat being...Beaten to death, for now.
Before her capture, Twilight had a simple small body, but months of eating three full meals a day - along with the occasional desert - later her body would make even a gentle-stallion stare. Her breasts were swollen to double Ds and threaten to go beyond that, her hips and thighs had also expanded, giving her a full and plump figure. Her butt, once a small but dignified shape, now - as well as her cutie mark - oozed out heavily on her flanks. The expanse of her shapely firm buttcheeks pleased the king greatly if his howl was any indication a week ago and it was much smaller back then.
These changes weren’t some luck in genes however. Sombra - be it his own ability or magic - morphed her body into a form of his desire while keeping other areas mostly untouched. Her face remained unscathed of any fat, the same goes for her arms, and if her stomach wasn’t so bloated she only had the “right” amount of flab for Sombra to play with. She had the ideal body that any lust-hungry stallion, and maybe a mare or two, would want to feast on.
His magic had other side-effects, though: her horn looked as if Sombra had sucked it raw with how red it was but it lacked the curved clawed-shape like he has. Her lavender pelt became a darker violet, and her mane had went from a deep purple to almost becoming black with her streaks now just two different shades of red and her cutie mark also went from a pink to now a red star.
The changes of herself also change the way Sombra treated her. At first, he was content for the mare as somepony to share his bed with and administer any of his needs. Twilight struggle doing the latter; lacking any experience in hand-jobs and sucking a stallion's shaft as well as not wanting to pleasure him, but Sombra only needed to threaten to enthral her mind to make the poor pony comply. Twilight hated doing it, but it was better than suffering the same fate as his other prisoners when he takes control over their minds and shatters them as if their willpower was made of glass. She had to settle for what little resistance the king tolerated, but with him feeding her; plumping her; pleasuring her; her defiance eroded away like water against stone. Sombra will cut through eventually, but she will not make it easy, even if it is a futile effort.
She suddenly let out a gasp as the rod lodged deep within her was pull out of her. The magically created rod dangled in front of her, wet with her juices, shame crawled within her. It was one of the newest additions from Sombra, an appetizer to what is to come, once she finishes her deserts, and what she just wolfed down was her last.
The magically created rod began to dissolve away back into nothingness until it was needed again. Sombra adjusted himself on the bed; his stallionhood stroking Twilight, earning him a worried murmur from her, making him even more eager for tonight.
“What shall we do tonight, little one? Sombra asked staring down at Twilight, his voice husky with lust but his tone remained even. Twilight’s response was just another groan as she dug her face into his naked chest, but muscle was not easy to dig into, she closed her eyes tightly; giving her a grouchy look about her and her bat like ears were downtrodden.
She was both uninterested to play with her jailer tonight, hoping he would allow her to sleep. Sombra tsk at such rebelliousness, he batted her distant belly and said, “Come now, little one.” - Sombra knew her actual name; it was the first thing he asked when they entered the throne room on the day he bought her, but he instead used this nickname for reasons she didn’t care - “This resistance is pointless. You might as well tell me what you want.”
“No,” she answered in a weak groan
His first response was the contact of his warmth wet tongue on her horn gasping as it went upward in a slow shudder inducing lick, “Are you sure?”
“Don’t” she groaned out, again. Tiredness or the wine from earlier dulled her mind that finding words was like finding a daring doo volume I book in its original print.
Sombra chuckled at the display, “my poor little one, she is unable to articulate properly.”
She ignored the taunt, she just wants to sleep, let her sleep, please.
It was clear to Sombra that Twilight won’t play with him tonight, but that won’t stop him. He again began to poke and prod her body - feeling her thighs, squeezing her breast - and began listing what he wanted to do for tonight, “we could do top and bottom again...hm, but that would be boring, wouldn’t it?” he licked Twilight’s horn again, making her shiver.
“Perhaps thee should suck my spear and jewels” he chuckled darkly adding a touch of old equestrian. Twilight’s response was another throaty whinging of disapproval.
“You’re right, only one of us will be in bliss… hm,”- he began to rub her buttcheeks - “It has been a while since we played with these, it would nice to watch them jiggle while I rut you…” Seconds past, Twilight guessed he has decided it would be butt play tonight as he moved her forward to get her into position.
But then he felt his breath so very close to her left ear and said “Actually, let’s do top and bottom again... only this time you’ll be on top.” The response shocked her eyes open and she stared at his gleeful expression.
His face remained unchanged, her heart beating with fear as she realises he wasn’t joking.
“N-no I can’t-”
Sombra cut her off, “you had your chance to decide, my silly little one, or would you rather I be more… forceful?” His eyes began to glow along with his horn, smokes of black and green billowing out from it.
Twilight immediately knew what he meant and with a soul-crushing sigh, she accepted his demand.
Twilight moved off him and Sombra settled himself lower onto the bed, resting his head on the pillows. Even completely flat the length of the half circle-shaped bed had room to spare for not just the two of them but another 2 - maybe even 3 - like pairs, perfect for an orgy of couples...or just one harem for him.
Twilight looked at him, most unicorns would normally have a small stature compare to the other tribes, - especially the earth ponies - although they can build strong physiques like her brother and the royal guard have, but Sombra’s would make even the strongest unicron look like a weak colt in comparison. He wasn't a chiselled mass of pure muscles and abs, but his tight abdomen, his powerful arms and strong legs made him more than a match against Royal guards and earth ponies.
It made her ponder if this was common with whatever his sub-race he is from. He could possibly be a cross breed of the tribes or-
“I’m getting soft~, little one” the annoyed yet teasing voice of Sombra reminded Twilight what body part she of his body she should be focused on.
Again, Sombra did not share the unicorn tribes’ ‘modesty’ when it came to his shafts size and length; its intimidating half-a-leg height would bring even an experience mare down to a twitching wreck if his girth didn’t already bring them to orgasm.
Twilight already had it inside her many times from both ends; stretching the walls; its length seemingly endless, she always wonders how she could have survived that monster of a shaft; it’s a wonder she could even still talk given how many times she had to deep throat it.
Normally, Sombra started it and guide her in what to do. Now she has to start it. And that gave her an idea. She may not be capable of fighting him directly, but there were other ways of resisting.
He watched her move into position, he could see her nervousness from her shaking form, and giving the amount of time she was taking, she got cold feet as well.
“Litt-” before Sombra could even utter a word he felt his tip of his shat being enveloped, only to feel the rushing motion of her ramming down right onto the base of his pelvis with a force of a wrecking ball.
Sombra coughed like he was choking and breathed shakingly as Twilight's butt teased his balls a little too hard.
Should have held her Sombra wheezing mind realized.
He opened his eyes to look at Twilight. She fared no better if the tightness of her face was anything to go by. The only pleasant scene from this disastrous start was her mammaries sloshing up and down and he couldn’t even enjoy the view at this painful moment.
“S-sorry,” she apologized, showing off her best sad puppy dog eyes and equally sad ears look.
Sombra just sighed, “It’s fine... just go a little slow-” Twilight suddenly rose herself again and went down just as quick, she gleefully enjoyed his yelp from another painful attack which she quickly responded with another 2 painful piston motions on his shaft.
“Little one,” he said with a growing anger inside his throat, “you’re doing it too fast, here, let me show you how it’s done” he reached for Twilight’s sides, but she moved again
“Sorry, master” Twilight said in an obviously sarcastic way, “I told you I didn’t want this,” she rammed into him again, “I just don’t have the strength to go down any slower than this!” she explained- bouncing up and down on his “poor” abused shaft.
Her playful tone ringed into his ears. He growled, this game was going on for far too long and his nerves - as well as his shaft - were drilling at him to take control.
He spoke again with added anger this time, “Then let me show you-AH!!” Twilight slammed into him again.
Twilight wasn’t exactly enjoying the abuse she was doing on her marehood, but it was worth seeing Sombra being uncomfortable “Don’t worry,” she spoke “I-I’ll get the hang of it” - she rose again - “I just. need. A little. practice!” She attacked again, but the thrill she was having was drowned into an ocean of dread.
“Enough!” Sombra roared. Not just of pain, but with both fury and patience lost. Twilight froze in stunned silence, she stared at him and he was staring back at her with his furious and now glowing green eyes that had purple smoke emerging out of them, but the red irises still watched her.
“I-I’m Sorry,” fear flooded her voice, “I-I did-didn’t mean to-”
“Too late for that,” Sombra suddenly grabbed her by the sides and flung her to the other side of the massive bed; the bed creaking at the sudden change of positions of the two ponies. Sombra was on top now, the mare below was visibly trembling, fearful at what he was about to do and Sombra wanted answers: truthful ones. He charged his magic- an aura of red surrounded his curved horn at first, then sparks of purple, followed by flames of greens and black that devoured the red aura like a kindle to flame.
Twilight knew what he was about to do, she tried to move but his weight held her legs while her arms were stretched to the sides like a t-shape cross and Sombra’s hands held them in at a vice-like-grip around her wrists. “Sombra, p-please, not that,” she pleaded, but Sombra ignored her as the spell was ready to be cast.
With an exhale Sombra unleashed the spell- wisps of shadow emerged from his horn and swam straight into both of Twilight’s ears.
She let out a terrible shriek as she felt the magic worm inside her and reached into her mind.
The magic felt like icy needles that injected themselves onto her will and soul, ready to pierce into her psyche and string her to his will. She remembered the last time this happened, it wasn’t easy to forget: she tried to flee from him the first day they met, and she felt first hand what many victims had suffered. The needles nearly rupturing her very sanity as he ordered her to stop, he had to carry her back into his bedroom because she was an immobile sobbing wreck for that entire day.
She never wanted to feel that pain again, and now her little act had doomed her.
At least she believed it did, but the needles - while gully pierce her mind - didn’t go any deeper, they were just a hand; holding onto her head, but one wrong move, or answer, the hand will crush everything that made her Twilight.
Sombra watched her squirm as the last wisp went into her ears. She stopped moving and open her sad looking eyes, green, the same as his, she is enthralled to his will now.
With a sigh Sombra released his grip off her wrist, but still stared down at her. Twilight laid there as if she were a corpse.
Finally he spoke, “Now, little one,” - Twilight looked at him with no emotion - “you were never so bold to the point that you would actually…” he paused for a moment, finding the right word to express his discomfort, “irritate me in such a way that it would end you up in this situation.”
“What changed?” he asked.
She felt the needles press down ever so slightly, threatening her if she does not tell him the truth.
She turned, facing to the right. Sombra looked at what she was staring at: an empty wine bottle.
He chuckled slightly, “Liquid courage, eh?” In a blink of an eye, he brought himself dangerously close to her; nose to nose. “I know it’s more than that, I can sense it. So start explaining, or else,” he said, tightening the needles grip.
“I didn’t want to” she answered
“Little one-”
She interrupted “You always wanted it, always claimed me. I never wanted it; shouldn’t want it; couldn’t want it” she admitted.
Sombra was puzzled for a moment...then he realised what she meant.
“Of course” - he chuckled at the simplicity of it -”I always “claimed you” told you what I “wanted,”” he rose, his anger replaced with amusement, “You clever girl, reasoning for your own sanity, that deep inside you enjoyed this, until I gave you this little independence, you had to take some action.”
Sombra applauded her, “I must say, little one, most mares I’ve conquered would have given in by now, your will is most impressive.”
Tears started to form in her eyes, but Sombra “comfort” her, “aww, don’t be sad, my little pony, I won’t punish you. In fact, tell me what else ails you and I shall put your heart at ease.”
Twilight answered “M-my stomach.”
Sombra look down at the bloated belly, its red tautness did made it look unpleasantly sore. Sombra looked at Twilight with a smile on his face “Yes I’ll settle it down, but first-” Sombra snapped his fingers and just like that the Icy needles faded away and her eyes return to their normal colour save for her still slightly red irises, “- there, now for your sore tummy” He teased.
“Why?” She asked
“Huh?”
“J-just why don’t you end it?” the little drops of tears from earlier now became a flood over her face, staining the quilt below, “Why don’t you just take my mind; make me your slave; why do you keep playing these games?!”
Sombra remained silent.
“What d-do y-you th-think I know?!” she was choking in hysteria, not caring what she said, “That I’m some spy, some prized prisoner to parley with, That I’m valuable?!” She sobbed uncontrollably, “Y-you might as well make me into a mindless whore because, I. HAVE. NOTHING!” she hiccupped, defeat had wrapped its cold hands around her soul, “I am nothing.”
The silence lingered, Twilight having drained out all her years of misery in front of the tyrant’s eyes. Sombra remained silent, he wanted this to happen, have her explode, but this was not the results he wanted. Time for a new approach, and maybe a little truth as well.
“I could do that: make you into nothing but an obedient slave to pleasure me.” He admitted. She believed what that answer meant and closed her eyes, awaiting her fate.
“But you’re wrong, Twilight.” Twilight heart missed a beat, her eyes open, filled with shock not just for his response but also saying her name that she believed he had long forgotten.
“You are not some useless mare, in fact” - he drew closer again, but his face was gentle and somehow...kind, “You are more valuable than you realise.”
“How- “she was about to ask but Sombra interrupted her with a deep kiss, making her heart miss another beat. They’ve kissed before, but this was tender compare to the usual feral roughness he would normally play on her lips and tongue. It was a moment, but it was pleasing warmness she hadn’t felt for so long that she let out a sad whine when it ended.
Sombra went on, “when I first set my eyes upon you I sense something, it was only when I could examine you in the throne room did I see the vast power you held within you,” he went on,
“For whatever reason, you’ve never unlocked your potential and it remained hidden from you.”
Sombra circled a finger around her breast while he revealed the truth to her, “It’s why I’ve been bedding you, not just for my own pleasure, but it’s in-fact a ritual to give you the energy needed to ignite your own power, why do you think your pelt is changing or why you haven’t become pregnant yet?”
The pit of doubt was endless for Twilight, “There must have been a simpler way to corrupt me.”
“There is,” he admitted, “But believe me, words cannot describe the agony you would have felt if I did that ritual”
Twilight shuddered at the thought, “why not tell me then?”
Sombra scoffed at the question, “Would you honestly accept my offer of power, the same power that I would likely use against Equestria?”
Twilight nodded, she would never betray Equestria just to awaken her potential,
at least not at fi- Twilight banished those thoughts with another question “Why humiliate me then?”
Sombra sighed, moving to the right side of her and rubbed her side affectionately before he spoke. “A mistake in my part,” he went on, “Dark magic is powered by negative emotions; anger being the most potent. I believed that humiliating you along with my….’forcefulness’ on you, you would eventually lash out and awaken your power. But instead you wanted to play the long game: Holding out until help arrives or I grow bored of you.”
Although, you did find your own “opportunities” to hurt me but I wouldn’t punish you dearly for”- he rubbed his crotch remembering the unpleasant event from earlier - “normally.”
Twilight asked her last question, blushing as she spoke, “then fattening me up was also part of the humiliation or to help power your ritual?”
Sombra chuckled and he grabbed her ample buttcheek, earning him an adorable yelp from Twilight, “I just like thick mares and you wear it all quite nicely”
Twilight wasn’t amused by the compliment. “So… what are you going to do now?”
Sombra listed his ultimatums, “You have two choices: we continue on and try to unlock your hidden power, it will still involve me mating with you, but I promise you it will be the greatest of pleasures, if that doesn’t persuade you, then you can leave.”
Twilight couldn’t believe the second choice “Really?”
“Yes, leave my kingdom if you wish and journey back home,” Sombra said.
“Why not imprison me,” Her inner self slapped at her stupidity.
“That could be your third option if you are that noble, though that would’ve made option one even more appealing, wouldn't it,” She nodded, “So, Twilight-” He wrapped his arms around her; their cheeks brushing together; she could feel his lower mass twitch in anticipation, “-What will you choose?”
She should pick the second choice, if he is being truthful at all, then she could be home again...But.
She remembered the moments, situations that if she had any power she wouldn’t be so helpless against tricksters like that Trixie who made her float helplessly in the air for just asking how she manage to beat an Ursa Major, able to help against the changeling invasion and save Cadence, or not be in her current predicament.
Other thoughts plagued her, she knows that Sombra has been spending more time on her than his other slaves, if she leaves then he will take out his frustration on them, there was also the fact that the choice she is about to make was influenced by Sombra’s twisted magic inside her.
She turned around to face him, their noses touched. If he wasn’t such a monster, she might have fallen for him.
she might have done just that.
“I’ll stay, aand you can “take” me.” His eyes shrank at her acceptance. He chuckled, but not in a twisted way.
“Twilight, you never cease to amaze me.”
Sombra sat on top of her again as he rubbed his red aura infused hands on her stuffed stomach, melting away the food and adding it to her expanding frame. He touched all the right places which earned him erotic moans from the mare as her taut belly shrank back to its almost flat self, just a small layer of softness for curious hands like himself to play around with.
She could feel the changes: haunches thickening to rival that of Celestia’s, thick, mouth-wateringly thighs and rear, her hips grew as well to that of a mother's figure after bearing children. He’s leaving my breasts alone at least- upon thinking that thought she eeped in surprise as her breast bounced forth into the impossible E cup size. She blushed as they jiggled on top of her like bloated water balloons, Sombra grabbed them to settle them, only to squeeze them gently but with enough pressure that the tingling sensations assault the poor mares’ nerves. She tried to hold back her moans, but her whimpering only encourage him continue the massage.
Sombra grinned at the display. He tenderised them for a few moments - Twilight moaning with each sensation - then he descended to one of those glorious mounds and he gave an erect nibble a playful lick, once, twice then he enveloped it into his mouth and began sucking it.
Twilight howled, but he continued drinking the milk that poured out. He motioned his body as he continued to suckle her teat, grinding his body lightly on hers.
Countless times he drank with his last being the longest and with a pop he ended his attack on her breast. He had his appetizer, now was it time for the main course.
Sombra grabbed her legs, pushing them aside and expose her marehood. His teasing had made her wet; a natural lubricant for his shaft to enter her more smoothly. He began pushing the head in gently, in most nights like this he wouldn’t care about Twilight’s comfort when he began mating with her, but this time she’ll scream in pleasure rather than in pain.
He pushed in, only getting half in when he halted, hearing Twilight’s groaning discomfort.
she sighed happily as he pulled out only to gasp as he slides in again, deeper this time.
In and out again and again - deeper and deeper his shaft drilled in pushing through the walls, its muscles buckling from his constant ramming into her.
Thump, thump, thump, a steady rhythm along with lewd sounds between them; Sombra groaning, Twilight moaning.
With one powerful push, he at last entered her uterus- Twilight’s back arched slightly upward at the entrance.
Naughty thoughts persuaded Sombra to play around for a little, he agreed and he started rotating his shaft around like it was a tongue; licking around as if he was having a lollipop. She squirmed, unhappy with his teasing.
She tried to push and pull away to continue the sex, but all she could do was give him a show of her breasts bouncing and her butt kissing his swollen balls as she squirmed helplessly at him.
Sombra rewarded her futile efforts with a playful smack on her buttcheeks, she yelped and gave him an angry glare, not at all amused with his teasing. Sombra did relent, especially when she used her merger magic and started squeezing her balls a little too tightly, reminding him that he should have put on the nullifier ring after all
Disappointed at the sudden end of his teasing he did reginite his original routine with no less enthusiasm, he even craned down to her - still pumping in and out of - until his snout was just a hairs touch from her small one.
Twilight did wonder what he was planning now, tried to, but his constant assault in her marehood mangled her brain as it filled up with hormones and feral emotions. He could see it on her face: the heated blush on her face, the glazing eyes and the near constant panting and occasional moaning, she was getting lost in an ocean of pleasure, a pleasure that was nearing its final release if her flooding marehood and vice grip walls around his cock were ever a better hint than anything else.
But Sombra wasn’t finished yet.
He went for a deep kiss, Twilight welcomed it hungerly; even his tongue as it went for hers. His arms where between her head now so his weight doesn’t crush her, but Twilight had let her feral instinct take over, as she grab him with both arms and legs closing the tiniest gaps, fully feeling the grinding weight of both on top and underneath themselves. Sombra felt the vibration squeal of ecstasy as the two were still locked into a kiss.
She was getting close; the stream filling the dam inside her, each pounding adding more and more pressure until it couldn’t hold no more and release her climax into the river that is her marehood.
She should’ve cum in some previous strokes, but she paid no heed as she wondered why Sombra suddenly halted outside of her. She was about to whine at the emptiness only to screamed instead as he slammed into her with indescribable force, her eyes rolling back as the impact shattered her dam and her climax poured forth.
Except it didn’t.
It should have; she felt her inner mechanism pushing the lever and releasing the river, but nothing came.
That’s when she heard his eerie chuckling, fear swelling inside her as she gazed his green and red filled eyes.
“Payback.”- He shoved himself in again and she cried out both in pain and pleasure - “oh, don’t worry, I’ll let you cum, just the same moment when I do and I have about...” - another hard push into her - “Four more to go” He laughed.
Twilight was in an ocean of ecstasy, but pangs of pain started to emerge from having been denied her climax. she was bursting for release, but the cruel stallion was denying her for four more- he rammed in again - three more bucking goes.
It wasn’t just the pressure pulsing painfully inside her, there was something else...a burning sensation in her heart. She felt it a few poundings ago, but she thought it was her conscious making her feel shame for agreeing with this, but it is something else, something dangerous, and the burning is becoming an inferno around her skin
Another push, she felt the fire flare up and another stabbing pulse of painful orgasm denial.
She had to tell Sombra before it's too late, “S-Sombra s-s-s-stop-AAAH!” another push, only one to go.
“Just o-o-one more, Twily, ha,” He slurred out, his mind giving in to his feral urges, wanting - no - needing to finish this last attack, “It’s going to be a big one!”
Her pleas where distant echoes to him now.
Twilight begged and begged, but his shaft moving back for one final push, she tried to move away but he had her on a vice grip. He smiled, reassuring her that this will be an experience she wouldn’t forget, never realising her pleas where not of pain, but warnings of the fire inside her that was about to exploded out of her. He didn’t even notice her eyes were becoming blinding white light.
She tried one last time, “Som-” she never got the chance as He rammed inside her, breaking his seal gate that prevented her from climaxing.
A second of silence was like an eternity until Sombra roared, ejaculating his load, but he never got to enjoying it as Twilight’s own climax made her screech like a banshee and the supernova light that enveloped both and the room.
Celestia looked northward.
“Princess?” a guard asked, “is something wrong?”
The regal alicorn looked as if a tragedy had just happened before her eyes. She whispered to herself, “It can’t be…”
The light finally abated, but the spots in his eyes remained a nuisance, “well,” - he hissed - “not a bang I had in mind, eh, Twilight?”
He looked down, he was beginning to see again but his vision was still blurred. “Twilight?... heh, guess it was too much for you, little on-” He could make her out now, but he couldn’t believe it.
Twilight’s body had burned off the fat she had accumulated over the months returning her back to her modest self, but that wasn’t what shocked - although a smidge of annoyance at the loss of all that plumpness - the King.
“Y-you’re a-” he couldn’t believe what he was seeing, nor could he stop staring at those feathery wings. “-an-an Alicorn.”
He was laying on-top of a former unconscious unicorn now-turned alicorn. She has the catalyst, A very rare gift in some ponies enabling them to ascend to alicornhood, but to unlock it was even rarer than those who had it. And here he awoke one just by mating with her.
Fate had one strange humour.
He looked at her with more clarity and grinned at her other changes: near blacked pelt, an onyx mane with blood red streaks, her equally red and curved horn, and for some reason her bloodstar now had five white ones around it.
Not only did she accept an ascension she also let the dark magic change her into an umbral pony. This presented several opportunities for him, and none proved hopeful for Equestria.
“Oh Twilight, you are just full of surprises,” He laughed. A laughed filled with cruel and mad intent, that echoed throughout the crystal halls of the citadel, it even made the enthralled minds shudder in fear. But it was short lived as he noticed some wrong with her wings.
They were dissolving away. He growled, he could kindle the ascension, but lacked the right fuel to keep it lit. It likely meant her umbral form was temporary as well.
He would need to solve this, but his yawning mouth told him that tonight was over. The disappointment will have to be solved later, it was time for sleep. He went off the bed and levitated the still unconscious pony above it. He pulled the covers off the massive bed and settled Twilight back down, then he settled in, resting next to her on his side. With a flick of his finger the many layers of sheets and the bed quilt wrap around them. He rotated Twilight to face him. Twilight murmured and nuzzled his chest and then went back to her sex and accession induced coma. She’ll likely not remember any of this, Sombra guessed. Another yawn escaped his lips, “Sleep well, my princess-to-be.”
