Night Terror

5. The end of Twilight

Twilight turned over, rolling onto her stomach. The damp sheets underneath her belly felt warm, fluffy… the pillows under her chin soft and inviting. But she couldn’t focus on the comfort which surrounded her. Her psyche was a mess - a confused tornado of despair and excitement, fear and lust, disgust and desire.

“Do you expect me to lower myself to you, child? Raise your body from the bed. Stand.” The order had an amusement to them, a smugness. But the sharp bite at its end affirmed that this was no simple request.

‘I… I sh-shouldn’t… I w-won’t... ‘ Twilight’s eyes throbbed in their sockets. She was exerting every last ounce of mental energy to retain her self, to fight back. Why was it getting so hard? The swirl of her family’s faces as they were transfigured, the burning acrid smell of the slaughter and rape of her hometown, the death of Spike… all the thoughts were so hard to hold on to.

“I said stand.”

Shakily, Twilight’s body rose up from the covers. She could feel the wetness of two rivers of nectar flowing down her inner thigh, could feel the heat emanating from the cleft between her legs as her tail fanned the air. Her muscles shook, already stunned by the overloading influence of all the sexual hormones wafting through the air.

“Yes. Good, good! Now, stick your plot up. UP, child!” Nightmare Moon placed a hoof on the small of Twilight’s back, right between her shoulder blades, and pushed her down, pinning her shoulders to the bed, forcing the mare’s bottom up higher into the air.

‘No! NO! I… can’t… I can’t... ‘ Twilight moaned into the musky sheets, she felt her tail flag up through instinct, proudly displaying her teenage rear, the tight little puckered ponut quivering above her drooling, winking marehood. ‘I can’t… st-stop… stop… th-thinking…’

Twilight’s mind raced, trying to remember her mother’s face, her father’s, her brother’s… but each time she managed to picture them, they faded and melted… turning into that incredible phallus that huge pendulously between Nightmare Moon’s thighs. Gods above her desire yearned for it… burned for it! How could she resist? Why should she resist? What was the point?

“Oh my little broodmare, keep fighting - don’t give in so easily!” Nightmare Moon cackled, as she mounted Twilight.

‘Sh-she’s right! I… no… I can’t… listen to her… I must… res-sist? Or… should I?’

Twilight felt the heavy weight of the larger alicorn as her large hooves clopped down on either side of her head, depressing deep into the softness of the bed top. A wet slap against her own buttocks followed as Nightmare Moon slid forward, pressing her hips against Twilight’s.

“Ahhnnn…. Ff-f-fuck!” Twilight moaned out, her head tilting upward as she did. Her whole body quivered at the feel of hips hitting hers, her back arching and pushing upwards, begging to be rutted, as she twisted her clenching forehooves into the sheets.

“Sensitive little thing - I haven’t even entered you yet and you’re already moaning.” Nightmare Moon clucked her tongue.

It was true. Twilight’s lewdly debauched nervous system couldn’t sense that huge pole of meat inside her… only the slap of hips and the swing of balls had set her off. Nightmare Moon had instead thrust that huge stallionhood between the tops of the globes of her round, pert teenage bottom. Like a heavy, hot log of meat, it had slid up her arching spine, leaving a trail of sticky juice as it slowly ground up her back, the tip finally coming to rest just between her shoulder blades, as the massive pipe lay across its soon to be plumbed target.

‘H-huge… h-heavy!’ Twilight’s mind was churning, swirling, getting lost in the cacophony of instinctive, biological thoughts racing through her synapses, hard-woven in there from millennia of evolutionary need. Her body was shaking from the thought of such a stallion-ly breeding tool on her. The sheer weight of the thing pressed against her back. It pulsed with heat and blood… the flesh that had once been her mother now filled with a singular need to breed.

‘I… I w-won’t it… want it? Won’t… want… what?’ Her mind choked, hiccuping on itself as it tried to maintain a sense of self, a final shell of the ego. ‘I c-can’t… can… be her broodmare… her foal factory… h-her cocksleeve… CAN’T! Why? B-because…. Because…?’

Twilight moaned again, as her mistress began to pull backward, dragging her heavy stiff cock along the small of her spin as she did, sliding her huge black forehooves along Twilight’s body to steady herself, finally gripping behind Twilight’s hips, the hard edge of her hooves digging into the round of her ass.

Twilight mewled, wiggling her hips left and right, backward… her body desperate for the sensation of entry that was so close. She knew that the penis must not be far from her cunt now.

‘W-why? Why doesn’t she just… d-do it!?’ Twilight’s mind was boiling, not knowing why she wanted Nightmare Moon to proceed, just knowing that she did.

“Ah… so you do want this, my little pony?” Nightmare Moon hummed nonchalantly. Then pressed slightly forward.

The hot wide tip of her flare pressed against Twilight’s pussy. A small scream from Twilight’s mouth could only be stifled by biting into the sheets of her bed.

It was obscenely large.

The whole flare was pressing against the entirety of her folds, covering the lips with its width entirely, even going so far to touch the insides of her thighs. The dome-like protrusion itself was sliding an inch into her outer lips - beginning the process of spreading her, of mashing into her pink clitoris… like a lover gently pressing his tongue between his mare’s lips before he thrusts the whole thing deep down her throat.

She felt the squirt of her pussy as it sprayed out, meeting the hot cock-kiss with a splatter of welcoming lubrication.

“What a little slut you are, my previous broodmare. Good… good…”

“P-puh...pleasseeee…” Twilight choked out, her eyes blinking in different intervals lazily, tears of pain and pleasure coursing down her cheeks. Her body knew what it needed, what all of this love magic in the air required of her, as she thrust backward in plaintive little humps against the rigid iron behind her.

‘J-just… just l-let it end… let me m-melt away…’ Twilight’s mind despaired, seeking an end to everything, the pain, the sorrow, a complete surrender to Nightmare moon.

“No no no, if you want this Twilight Sparkle… You must ask for it. You. Deep there in your mind.” Nightmare Moon chided. “I told you I would break you, corrupt you… your whole body, mind, and soul. Give it to me… become my broodmare… my cocksleeve. Accept it.”

‘I… c-can’t… m-my family… m-my friends… w-what would they think… th-they’re watching me… I c-can…. Can… can I?’

Nightmare Moon twisted her hips at just the right moment, grinding the edge of her cockhead’s ridge against Twilight’s clitoris, sending a surge of corrupting lust magic coursing through the completely overwhelmed teen.

‘By Celestia… by Luna YES! YES, I WILL BE YOUR BROODMARE. I WANT IT. I WANT YOUR COCK, YES YES YES YES!’

Twilight broke.

Her pupils shifted distinctly, the bright purple irises warping and shifting into two heart-shapes as the last of Twilight Sparkle the student, the daughter, the sister, the librarian was lost for all time, her mind melted and reformed.

Now she was, and would forever be, Twilight the broodmare.

“Good girl.” Nightmare Moon hissed.

Then she thrust.

Twilight’s body spasmed and jerked at first. Under ordinary circumstances, there was no way that a mare could accept such a large horsecock… not even the largest most prolific whorse of Manehattan’s red-light district could even come close. But magic was afoot, and the violence of the Alicorn’s thrust saw to it that those tender, tight, hot-pink lips spread and permitted the huge flare to enter with a POP.

Instantly Twilight orgasmed. Her heart-shaped eyes rolled up into her head, body trembling and shaking as she squirted around the invading cock.

She could feel her vaginal muscles clenching, swirling around the thick, veiny shaft that had been her mother as it slid deeper and deeper into her body, far past anything that she had ever dared to attempt on her own. New parts of her were opening, flowering, exploding as her family entered her, strained her.

“A tight little cunt… It will need some working…” Nightmare Moon gasped as her first thrust slowed. “I shall not be gentle…”

Twilight felt the suction inside her as the cock began to work its way out of her. The huge, plunger-like bulge in her lower abdomen felt like it was dragging her guts back out with the outstroke. As the thickness of the coronal ridge approached her exit Twilight moaned again, shamelessly. The additional pressure of that thickness was pinching into the internal structure of her clit, sending more sparks shooting through her nerves, her orgasm still continuing, unabated.

And then Nightmare Moon thrust back in.

Twilight felt her breath driven from her as the cock slammed back into her, going deeper than before. The girthiness of the shaft below the huge head started to approach and surpass even the flare’s impressive diameter as more of the towering penis was plunged into her, stretching her wider and wider.

“OH… y-YE-s-Shhshhhhh….” Twilight’s coughing exhortation followed after she managed to catch her breath from being winded.

The head of her lover’s cock slammed up against her fornix, scarcely 14 inches deep into her body. Almost half of the monstrous stallionhood was still outside her, and she had already been filled to the limit of what her small pony biology had been designed to handle.

“I am not yet done.” Nightmare Moon hissed, continuing to press forward with her hips on this second thrust.

“Oooogfhhfffmmmnnnn.,...” Twilight’s mouth hung open in a rapturous groan. The battering ram of a penis was pressing against her womb, pushing it up and into her abdominal cavity, forcing her tight, twisting vaginal tunnel to accept more of the impossibly huge cock inside her.

‘It h-hurts… s-so… GOoOooOooood…..’

Through the intense sensations, Twilight felt her labia sting with sharpness. A new, wider hurdle was forcing itself into them, stuffing into her body. The huge, dark-grey medial ring pressed into the straining pink flesh, which strained and stretched, threatening to tear under the immense pressures of being wrenched open so violently… until… inexorably…

*POP*

The donut slid into her, wedging itself just inside the gates of her marehood.

A second burst of fluid ejaculation wracked through Twilight’s body, making her hips twist and pivot with insistence, doing their best to wedge more cock into her, while also expelling the lubricating honey as best it could.

But the seal was too tight, leading instead to a gushing explosion from all around where the dark-grey mare-cock met her hot-pink fillyflesh, released in a single liquid explosion, like a water balloon popping on a pin.

“Mmngggm-moreee….” Twilight grunted, her tongue difficult to work as it hung lifelessly out of her mouth, her drool slicking the pillow her head lay against. Her whole body was one thing now - one element. All of her purpose was to be bred, rutted, fucked by this tremendous stallion… to cum around that marvelous cock and coax it to release its glorious seed deep inside her fertile womb, so she could bear her stud’s foals.

She could feel that domed tip slip ever so slightly through her cervix, its burbling cockslit shooting a small squirt of potent aphrodisia-laced clear fluid into her uterus, her womb, the center of her femininity. Her mother was slipping into her most secret recess… her brother and father were leaking into her… her mistress was taking her, claiming her.

All of her belonged to that incredible cock now...

‘F-fuck… y-y-es… m-my… YES!’ She wanted more, wanted to lose herself to it. Become it. Worship it.

And back out again it came. It’s huge knobby ridges pressing into her velvety cunt-walls, straining her pelvic muscles outward as it passed, raking into the nerves embedded in that throbbing tunnel. Twilight could feel a bulge poking out in her lower belly as Nightmare Moon withdrew from her, inch by devastating inch.

“H-harder! D-deeper!” Twilight gasped.

*WHAP*

A stinging bite shot through her left flank - a bitter slap from her mistress’s hoof that left a painful welt over her cutiemark. The tremor of pain against the pleasant sensation of being stretched, against the saddening feel of being emptied as her lover’s cock withdrew… the mixture sent a tremor through Twilight, a gush of creamy marecum splattering in response to the new treatment.

“Patience, my little cocksleeve.” Came the grunting reply.

Twilight groaned again, eyes flickering. She could hear the lust in Nightmare Moon’s voice, the satisfaction. The feralness. She was so happy she was pleasing her stud, was drawing this out of her.

“I’m going to rut you good and hard little filly. Don’t make me break you.”

“P-pleasee….”

“These stallionly urges would have me shred you in an instant to slake my lust. Don’t. Tempt. Me.”

“PLEASE!”

‘Oh, Luna I want to be fucked so hard… I want to hurt… I want your big bucking cock to split me in half… oh, fuck oh fuck fuckfuckfuckfuck….’

“Graaaargh!” Nightmare Moon let out a snorting whinny, stamping one of her rear hooves.

Then she bucked forward.

This was no mere thrust, not like before. Now she was driving into her, impaling her.

The huge battering ram slammed up through her pussy, cramming itself immediately against her cervix… which could only hold it back for the briefest of moments before it popped through with a painful *PLAP*. It was like a guitar chord had been plucked through her entire body. She felt her muscles spasm and give out, losing any semblance of centralized control as it went limp.

She couldn’t sink to the bed though - her whole body was held up by the alicorn’s massive cock, like a pony being spit-roasted on some obscene flesh pole.

Twilight’s rear hooves kicked idly at the air, twitching and paddling unconsciously like a puppy held above a body of water.

Once inside her womb, the massive cockhead streaked through the delicate uterus, quickly embedding itself on the far side of her wall, pressing into the sensitive lining as it bulged a hoof-sized lump just above Twilight’s belly button.

Her body was never designed to take such a thing inside of it - not even close! It would be like asking a chihuahua bitch to be bred by a great dane - the biology just couldn’t work. Shouldn’t work. Yet she wanted it. Needed it to.

She could feel her guts - her intestines and stomach, deforming and displacing, making way for the huge cock as it embedded itself into her diaphragm, making it difficult for her to breathe. Her whole body had now made its purpose accommodating her beloved stud, this marvelous stallioncock. The priority of getting more of it inside of her superseding anything else - even the functions needed to keep Twilight alive.

“Blergh… breeghh….” Twilight felt herself vomiting into her throat, driven there by the plunging action of the huge organ inside her. The bitter taste of her bile was mixed with the wonderfully complex and heady ambrosia of the alicorn love-power laced pre-ejaculate she’d swallowed earlier.

“Bleh… y-yes!” She grunted, swallowing back down the gurgling backwash.

“You little whorse… little gutterslut! I’ll destroy you with my… n-n-nEIEEIIIIGHHH!” Nightmare Moon’s knicker shook the ceiling, her royal canterlot voice rattling the furniture in the throes of her passion.

She began to piston in and out now. Short, brutal strokes that pounded against Twilight’s body.

‘She’s… bb-ucking me! Yes! YES!’ Twilight could sense the chaotic nature of the thrusts now, no longer the measured and calm plan of the masterful corruptor. Nightmare Moon was losing her own mind to the burning lust energy throbbing through her new, difficult to control, male organs. ‘Break me! BREED ME!’

All she heard from Nightmare Moon were snorts and clacking teeth. All she felt was the stinging pain of harder and harder bucks, each more and more brutal.

Her pussy was a gaping drooling mess. The fattest part of Nightmare Moon’s base was now beginning to slide into her. Only a few inches… four, perhaps five remained outside of her on each thrust. Each time she bottomed out, Twilight could feel the swollen throbbing vessels of the immensely girthy base pressing into her very hip bones. Her fat clitoris was completely mashed into the wall of her labia, grinding with considerable force against the top of the mother-cock’s upper shaft.

Each thrust came with a splattering shot of clear pre-cum, a boiling hot, magmatic spray of lubrication inside her that barely prevented her from being torn asunder, that filled her with her lover’s essence… drove her chemical reactions to new heights - refueled her biological, neurochemical meltdown.

“AHahhahhhhHHhhnnnnnnGGHH!” Twilight convulsed, her brain freezing in a mini-stroke. She’d never stopped her first orgasmic contractions, but now something secondary, more powerful, dangerous exploded through her. A fresh wave of dopamine and endorphins coursed through her system, sending her into a small seizure.

All she was in that moment was sensation - just an input receptacle. There was no signal processing, no comprehension. Just pain and pleasure. Stretching and pounding. Melting and breaking.

Her pussy muscles fired wildly in every way, some fibers clenching, others relaxing. The twitching and swirling milking rhythms wracking through her entire body, as if the individual parts of her knew that they needed to take over for the absent central nervous system… needed to coax their mistress to unload in her… else they would be destroyed.

“N-N-NIEIIIIIIIIGHHHH!” A second, stong knicker came from Nightmare Moon at the new reaction of her victim, who had now truly become nothing more than a writhing mass of flesh containing her cock.

A crackle of black energy-filled Nightmare Moon’s horn and she gripped the thrashing teenaged unicorn’s purple tail in her mouth. With a hard yank, she pulled the hair tight, yanking the quivering dock upright as she did so. She hooked her hooves into Twilight’s hipbones, pistoned back as far as she could… then in one motion, released all of her energy - both magical and physical.

Twilight felt the energy coursing through her crackling through her whole body. She wasn’t sure if it physically rearranged her - made her capable somehow of accepting more of her mistress by expanding organs or bones… or if it was some magical deviousness - cramming more space-time into an equivalent area of realspace. All she knew was that she was now taking all of Nightmare Moon.

All of her mother.

The feel of those final inches slipping into her. The feel of that immense, dinner-plate wide girth breaking open her once-tight fillyhood. The Feel of the massive, pipe-like bulge expanding through her entire body. The feel of the smashing cock-end pummeling her womb.

Nightmare Moon had hilted her.

*THWAP*

The heavy strike of Nightmare Moon’s hips against hers filled the bedroom for the first time. Twilight’s head shot up, craning up reflexively under the immense sensational overload.

*PLAP*

Then, half a moment later - the feel of two heavy, wet impacts against her small, teenage teats.

‘D-d-dad! Shiney!’ Twilight’s mind blinked back into life. Her brother and father were now slapping against her with each stroke! Swinging up from where they hung pendulously beneath Twilight Velvet to smack into her teats and lower belly. It was as if they were reaching up to touch her, to remind her they were there with her! ‘Y-yy-yeshhh… I love you…’

Then, sadly, they swung away. Nightmare Moon was wrenching the whole incredible organ back out of her. A sucking, vacuum-like pressure followed its exit, drawing her body back in against itself as all those veiny ridges, rings and veins slid back out against her clenching cuntmuscles.

Her dripping, pink, labia quelched and sucked against the veiny cock being drawn from her. Each ridge and vein bumping against her clitoris at it did so, dredging sticky, burbling, mare nectar as it did. With a stunning *POP*, the steaming grey cockhead came free from her vagina, leaving devastation in its wake.

Her tight slit was a gaping, writhing chasm, her pink-insides squirmingly visible to any who may have looked.

“UNnnggh!” Twilight moaned, pushing her upper body back up off the bed and thrusting herself backward, desperate to stick that huge thing back into her body.

A blasting snort of boiling air poured over her upper shoulders, a stamping buck coming from behind her. Her stud was in rut now - wild and untamable, her boiling marecock menacingly quivering in the relatively cooler air, forming clouds of lusty perspiration in the heated area between their two nethers.

A stiff hoof found the back of her head, roughing gripping her mane, jerking it… then slamming her back into the pillow, muffling her wanton cry.

A moment later, her beloved gargantuan, monstrous, domination stallioncock was back. Back into her once-tight furrow.

Slamming into her.

An obscene squelching queef splattered out of her body as the cock quickly filled the void inside her, driving any trapped air out of the tight junction between cock and labia with a rippling vibration.

Inward she plunged, tearing through her pussy with abandon, rending her, smashing all the way into her again with her hips, hard enough to make her feel the Alicorn’s bones through the pert teenage buttocks being smashed under her fervent bucking.

*THWAP*

Then that heavy impact of those balls, swinging up and thudding against her teats, her belly… like a pair of shotput balls in a leg sock, smacking her with great momentum.

*PLAP*

There was no pause this time, no savoring of the feeling of fullness, of being completely hilted, of being bulged out. Her mare-stud no longer had time for that. As soon as the heavy balls had finished their swing forward, the dark princess was already pulling back, preparing for her next stroke.

A second hoof joined the first, pressing her head deeper into the covers, forcing her to raise her bottom up even higher in the classical face down - plot up style. This time Nightmare Moon only withdrew to the limits of her cockhead, not actually fully withdrawing… before slamming all the way back in.

*THWAP*

*PLAP*

Twilight’s face was being ground down in the soaked, stinking sheets, her nostrils her only source of oxygen as she struggled to gasp for air, her body completely overpowered by her lover’s superior strength. The wild stallion was increasing speed now, working up into a maddening rhythm.

*THWAP*

*PLAP*

Each thudding impact seemed to come harder and faster than the last, like the pistons of a great locomotive, slowly building strength as the boiler reached a steam-whistle emitting pressure.

*THWAP*

*PLAP*

*THWAP*

*PLAP*

*THWAP*

*PLAP*

It was a jackhammer now, thudding into her harder and harder and harder. She could feel the ancient wood of the royal bed bending, cracking under each thrust, as Nightmare Moon fucked her straight down, dropping all of her weight and power through her, slamming her tremendous cock into her body.
