The Night To Last Forever

I: Bad End

The cold air of the gutted castle lingered, as Twilight stared ahead at her nemesis. Nightmare Moon was stood atop a plinth in the centre of the hall, laughing maniacally as she lowered her gaze to meet Twilight’s. Her laughter trailed off, as a smug smile crept across her lips. Twilight was stood with her head down, getting ready to charge. The Mare in the Moon stared down, dumbstruck. “You’re kidding. You’re kidding, right?”

“YAAAARRRGH!” Twilight screamed as she ran forwards towards the Princess, her horn sparking violently as she charged a particularly lethal spell. Small flecks of light flew forth as sparks jumped outwards, dissipating in the air. As she approached Nightmare Moon she threw her head to her side and back again, launching a bolt of intense purple energy directly at Nightmare’s face. But the bolt merely froze in mid-air. Twilight skidded to a halt, tripping over her hooves as she hurriedly stopped. She couldn’t believe it. With as little effort as a flick of the hoof, Nightmare Moon had stopped the bolt in its tracks. It hovered just a few inches in front of her face - pulsating and twitching sporadically – as Nightmare Moon grinned down at the shocked unicorn. Her wide, toothy grin was bathed in a warm purple light as it emanated from the bolt. And just as easily as she’d held it in the air, she launched it back at Twilight. It crashed into her chest in an explosion of pure energy as Twilight was flung backwards across the castle. She collided with the cold brick of the far wall, and slid down into a crumpled mess on the floor.

In a heavy daze, she couldn’t comprehend what had just happened. She’d been shown a huge variety of permutations of magic spells during her studies in Canterlot. She’d been taught the different types of offensive magic, the art of levitation, the intricacies of magical manipulation. The full works. But magic was unique to each unicorn. As Celestia had told her, “When you cast a spell, that resulting magic is as unique to you as your cutie mark is. It cannot be influenced by any other unicorn. It cannot be changed, it cannot be stopped. Your spells are your own, so you must be careful. You won’t be getting…” Twilight’s memory of Magic Class slowly evaporated as she drifted back to reality. She could hear the sound of hooves on stone, as someone sauntered towards her.

“Now, young girl, you don’t have any idea what you’re doing here, do you? You waltz into my castle with your idiotic friends, thinking you could take on the world and win. But look at you.” She gestured down at Twilight’s prone form, laughing at just how pathetic the unicorn looked. She had burrowed her head down in between her fore-legs, like a young filly hiding from thunder. “You’re an embarrassment. You and your friends. Disgusting parasites upon this, my rightful kingdom.” She threw her hooves apart grandly and waited there, as if expectant of a round of applause from an imaginary audience. She looked back at Twilight, who still lay prone with her head in her hooves. Nightmare Moon rolled her eyes, before stamping her hoof on the floor. The sound echoed around the room, overlapping itself as it slowly faded away. “LOOK AT ME!” Her quiet, aloof tone had been replaced by one of pure wrath.

Letting out a short yelp of fear, Twilight lifted her head from her hooves and stared up at her attacker. “I’m… sorry. Please let me go.” The anger was immediately gone from Nightmare Moon’s face, as her lips again curled upwards. A short snicker escaped her as her horn began to glow a dark blue, casting a dull light upon the room. Being the dead of night, there was little natural brightness in the air, other than the slight, pale illumination of the moonlight. The light from her horn quickly snapped away as she finished casting her spell. She had produced a dark leather collar. Attached to the collar was a short, chunky leash. But this leash was odd, different from the ones Twilight had seen the dog-walkers carrying back in Canterlot. At one end was a clasp as usual, but at the other end there was another clasp, instead of the more normal handle. It was as if it was a leash designed to attach two dogs to one another. What on earth was this devil planning with it?

“Here you go, precious. Put this on, and you’ll feel so much more like your proper self.” Nightmare Moon slowly levitated the collar down and around Twilight’s neck, before clicking the buckle shut. She did it slowly, making sure the leather nicked and pulled at Twilight’s fur as it wrapped around her neck. She wanted Twilight to feel everything. “Now, young one, that harlot Celestia has probably told you quite a bit about me. You obviously felt that you knew everything you needed to, or else you wouldn’t have rushed into a mission so,” she paused, choosing her words very carefully. “…deeply regrettable for you.” Twilight squirmed underneath Nightmare Moon’s legs, trying desperately to escape. But it was no use. Nightmare Moon’s magic held the leash firmly in place, leaving Twilight immobile beneath her adversary.
“Here this, I have something to tell you that Celestia probably failed to mention. You see, I’ve been rather dishonest with you. I’ve been hiding something. But as you ponies teach, one should love and tolerate everypony on this forsaken husk of a world. So I’m going to show you what I’ve been hiding.”

Nightmare Moon closed her eyes as she concentrated. Her horn bathed the room in the same blue hue as before, as this time her whole body was slowly engulfed in the light. Twilight shielded her eyes, almost blinded at such close proximity. The light vanished, leaving Nightmare Moon stood before Twilight again. But now though, there was something new. Something horrific. Twilight wretched.

Hanging between Nightmare Moon’s legs was a gargantuan set of male genitalia. It wasn’t just big, it was… freakish in its size. The twitching cock hung down limply, but even flaccid its head was rubbing against the castle floor. At the base of her cock was something strange. Just before the skin of her sheath, a large metal shackle was clamped around her member. It was clearly too small for a cock of that magnitude, if it was even designed to go around a cock at all. It dug into the flesh, pushing out the veins around it, causing the whole cock to bulge and pulsate in a strange, almost alien way. As Twilight's eyes moved backwards along the shaft, her mind settled on Nightmare Moon’s ballsack. It was a disgusting sight. To say they were oversized was an understatement. The monstrous testes were so swollen, any normal pony would’ve needed a cart in order to move them around.

Nightmare Moon caught Twilight staring, her mouth hanging open slightly. She yanked on the lead, pulling Twilight right up against her urgent, purple member, forcing Twilight’s face against its head. A hot streak of pre-cum smeared across Twilight’s cheek. It smelt odd. Not unpleasant, just strange.

“Do you like them, my dear girl? Let me explain. 1000 years ago my sister banishes me to the moon. 1000 years I am trapped up there, with no one to talk to, no one to play with. And she knew that. So the last thing she did before banishing me was bestow this gift unto me.” She pushed Twilight’s muzzle deep into the steaming flesh of her scrotum, holding her amongst the warm, musky folds of skin. Twilight gagged, as she was forced to take a deep breath of the pungent smell. She pulled herself away, shuddering in horror as a niggling part of her mind wished it was still devouring that scent.

“But not content with giving me this mighty cock - and no whore to break with it - she gave me the full prisoner treatment.” She shook her cock from side to side - rattling her shackles - smacking Twilight to the floor with her member in the process. No sooner had she hit the floor Nightmare Moon tugged her to her feet again. She continued. “She threw me into these shackles, before casting a spell on me for good measure. As long as I remained on the moon, I would be eternally hard and unable to escape my heat, leaving me in constant lustful agony. No matter how many times I beat the seed out of me, the lust just came back, clawing at my mind. 1000 years needing to breed, and no one to do it with. I could feel myself swelling, churning, desperate to pump my seed into some needy bitch. But now that I’m back in Equestria those spells no longer affect me, so I just need to find someone to sate my needs. And that’s where you come in.”

Twilight desperately jerked on the leash that bound her, trying to break free, to no avail. She could do nothing but sit there as Nightmare Moon lined up her cock with her mouth. The smell she had gotten used to, but she could never get used to the size. And that was just looking at it. She grimaced as she felt Nightmare Moon pushing her flared, rock hard shaft against her lips. She tried to move away, but she had been pushed up against the castle wall. She was practically pinned in place by this shaft. There was nowhere she could go. And there was only one place that cock could go.

And it did.

Nightmare Moon broke her way past Twilight’s defences, and slowly forced her cock into her newest subject. She was overjoyed. 1000 years of waiting for a lucky mare to be her special cum-dump, and she had found that mare. And she had turned out to be none other than the Princess’ protégé. How perfect that was. Now all she had to do was break the slut.

Twilight hacked and spluttered as the massive slab of meat slowly slid further and further inside of her. Nightmare Moon inched forwards at an agonisingly slow pace, lingering in the joy of her prisoner’s warm innards. She stopped - only about a third of her length inside the unicorn – as she watched Twilight’s throat bulge profusely, stretching grossly in an effort to accommodate the vast member that was lodged within her. Twilight looked up at her assailant, her eyes full of desperation and fear. She shook her head as much as she could - what with the spear holding her head in place – and lifted her hooves in a praying motion. Tears were rolling down her cheeks, mixing slightly with the pre-cum that had already begun to drip from the corners of her mouth.

“Oh, Twilight, what are you trying to say? You want me to stop? You BEG me to stop? Well, considering you are a little busy to talk, I’ll just have to guess what you want. And I’m guessing… you want to be my cock-whore?”

Twilight continued to stare upwards, her sadness turning to cold, dark fear. She watched, helpless, as the other end of the leash levitated into the air. Nightmare Moon positioned the second clasp against her shackle, and hooked it into place upon one of the dangling chain-links. Twilight shuddered.

“Now, young lady, this cock is a part of you now. So long as we are attached, it’s not going anywhere. It can’t.”

Nightmare Moon lurched backwards, as if in an effort to remove her penis from her slave. As she tried to move away the leash went taught, and the air filled with a loud crack of leather. Twilight was pulled forwards from her back onto her knees, but the cock didn’t go anywhere.
“I’m stuck inside of you, until I’m soft enough that I can work my way out. And I’m not going to go soft until you pleasure me. What else will you do? Wait it out?” Nightmare Moon laughed cruelly as she slammed her hips forwards, burying her cock deep in Twilight’s insides. It was now the turn of her stomach to bulge violently, looking as if it was threatening to burst. “You can’t wait it out. I’ve been hard for a 1000 years, you think it might suddenly go down by some miracle? Ha. There are no miracles for you now.”

As Nightmare Moon bucked into her, Twilight’s muzzle butted painfully against the cold, jagged steel of Nightmare Moon’s shackle. Twilight spluttered violently, as cum shot from her mouth and nostrils. She couldn’t believe what was happening. She looked around for some sign that this was all a horrid dream, but there was no release for her. She could only accept it as Nightmare Moon began to piston her member back and forth into Twilight’s mouth. She screamed against the flesh that filled her, punching her hooves against Nightmare Moon’s underbelly. She scoffed.

“Please, Twilight, don’t pretend to be something you’re not. I’ve watched you from the moon. I’ve seen your dreams. I know what you got up to as you grew up. I know what Celestia made you do when you were a filly in her class. I’m surprised you survived your time with her. Your little asshole must have been raw. And I know what you did with your Dad when you graduated. Sure, his cock down your throat is timid and laughable compared to mine, but you aren’t a stranger to the rough stuff. We both know you love it.”

Twilight twitched and shuffled from side to side as the hulk of purple, corrupt meat slammed into her again and again. She could feel a warmth to her very core as it spat heavy dollops of pre-cum into her belly, sloshing around audibly inside of her. The motions of her captor were becoming faster and faster as she pumped her length in and out, gasping as Twilight’s throat contracted around her length. Twilight’s struggles for freedom had begun to subside. She slowly slumped on her haunches, accepting that – like it or not – there was no way she could break free. There was little she could do but retreat amongst her own thoughts, as her belly began to swell slightly with the volume of pre building up inside her.

“This is so disgusting!” She thought to herself. “Where are my friends? Where is the Princess? Can’t anybody help me?”

“… But why would I want help?”

Twilight’s eyes widened with fear as she realised what she had just thought. No, surely not? She couldn’t let Nightmare Moon corrupt her! She couldn’t fall at such a humiliating hurdle. She had to stay strong! But the thoughts were there. A tiny, niggling voice in the back of her mind that was gagging for Nightmare Moon. A voice that revelled in the delight of choking on her enormous cock, which continued to thrust its way in and out of her throat. A voice that wanted Nightmare Moon to break her - destroy the Twilight that once was - and transform her into nothing but a cock-addicted baby factory.

She had to fight it.

Nightmare Moon grinned. She knew what the unicorn was thinking. And she knew the unicorn would lose. But perhaps a little extra incentive was needed to tip the balance.

Nightmare ceased her thrusting, giving Twilight a joyous moment of recovery from the onslaught. Looking down past Nightmare’s cock and balls, Twilight could see Nightmare Moon's tail beginning to drift slowly towards her. It was forming into that mysterious mist that Twilight had seen Nightmare Moon transform into beforehand. But this mist looked odd. Different, more… solid. First the tip, then a longer stretch of her tail formed into a solid, writhing mass. It looked like a powerful vine that would’ve hung from the trees in the Everfree forest. But unlike a vine, this mass moved with purpose. It was like it was alive.

This new form slithered towards Twilight from underneath Nightmare Moon. It rose slowly into Twilight’s vision, hovering there for a second. She stared at this monstrosity as it slowly brushed itself against her face, leaving a trail of an odd, mucous-like substance on her fur. She sniffed at it cautiously as the ‘tentacle’ sank back down towards the floor. The aroma of this mucous was incredibly powerful, but it was not a smell she could put her hoof on.

“It smells quite nice…” The voice piped up in her head again.

Twilight concentrated as she tried to shut it out.

“Imagine that beast sliding down my throat. Oh, the things it could do to me. I wonder if I could take her bloated horsecock and her tail in my mouth at the same time. Perhaps I should practice, it would please her so!” In desperation, Twilight smacked the side of her head with her hoof. The voice was suddenly gone again.

Back in the room, Twilight could see what this mass was actually trying to do. She began to wail uselessly against Nightmare Moon’s cock as the tentacle pushed inquisitively at her pussy. She snapped her legs shut, crushing the tentacles head between her thighs. Now it was Nightmare Moon’s turn to let out a yelp, caught off guard by her slut’s insubordination.

“You insignificant wretch! What in Tartarus do you think you’re doing?” Her horn lit up as two pools of magical energy gripped Twilight’s thighs and thrust them apart, smacking her legs back down onto the cold stones beneath her. “And to think I even considered treating you gently,” she sneered to herself. Twilight clenched her muscles desperately, but she knew it was useless. She could feel the rounded tip of Nightmare Moon’s tail slithering into her moist hole with minimal effort. It continued to push its way further and further into the unicorn, constantly lubricating itself as it continued to emit that same mucous-like substance from its tip. Twilight squeezed her eyes tight as she could feel her belly bulging to accommodate this additional beast in her tight interior, alongside the member that bulged her throat out so distressingly. It finally stopped travelling, coming to rest deep inside her mid, before starting to thrust slowly and methodically in and out.

As it did, Twilight could feel the cock moving in her throat again. She kept her eyes pressed tightly closed, desperately begging to anyone beyond that may have been listening.

She hated every second of this cruel abuse, but especially hated how it was starting to feel good.

Suddenly, she felt the urge to open her eyes again, and face her captor head on. Her eyelids crept upwards, as the cock before her came into focus. Eyes now wide, Twilight realised. Nightmare Moon wasn’t thrusting against her face.

Twilight was the one doing all the work, sliding her head back and forth along the shaft that occupied her throat. Nightmare Moon was just stood over her. Other than her tail thrashing madly at Twilight’s nether region, she stood motionless. She wore a grotesque smile across her face, mad with lust and power. Her eyes were sharp, alert, and staring deep into Twilight’s very soul. A drop of drool that had built upon her fangs dropped towards the floor, bursting against Twilight’s muzzle as she worked the cock before her. Her lips slowly parted as she spoke.

“Ha…ha, it’s happening. It’s really happening! Oh, how long it has been! Twilight, dearest, you REALLY didn’t know what you were getting yourself into by coming here. I once had the entirety of this nation at my hooves. Stallions and mares alike were desperate to guzzle down my seed, to breed me and one day have the honour of birthing my foals. The only thing that brought those ponies pleasure -once they bore me said foals – was the hope their children would inherit tools as mighty as mine so they could be fucked senseless by them too. My magic is far more potent than your Princess would have had you believe. Potent enough to break the mind of even the strongest pony that faced me. And you are no different. My essence has been deep within you this whole time.” She motioned vaguely at the tentacle that continued to thrust aggressively into Twilight’s battered vagina, leaking cum from her ballooning belly onto the floor. “And my essence has twisted your mind and body alike. It has touched your very soul, and turned it black. Your body is obviously completely under my spell already, but I wonder if your mind is too?” She stared closely at Twilight’s face and gasped with delight as she saw a single tear rolling down her new cock-whore’s face. “Ha! You are still in there! Oh, you must be loving this! The knowledge that your body is dedicated to me, and there is nothing you can do but scream internally.”

Twilight could only watch herself as she lunged forwards and back, drawing huge gulps of cum deep into her belly as she swallowed Nightmare Moon’s member eagerly. She sobbed as she felt one of her hooves lifting itself up to the base of this disgusting, euphoric shaft and begin to caress and massage it. It ran its way along her skin, manipulating the flesh as it settled on the shackle that was still locked firmly in place.

The corrupted voice within arose again, louder and stronger than before. “Come on, this is so great! Why would I ever want to deny this? I would be the perfect slut for this beautiful goddess! Just imagine what I could do if I completely submit? Oh, what I would give to feel that angelic cock force its way into my anus! To feel that rock hard slab pushing into me, manipulating my useless little body to accommodate itself! I want to feel myself be stretched and bent around her, so she can use me as the meagre fuck-toy that I am! And imagine the babies she could pump into me!”

Twilight tried to fight this alien presence in her mind, but she simply couldn’t. It was too powerful now. Besides, perhaps the voice was right? After all, the sensations of the cock in her mouth and tentacle in her pussy had both filled her with a sense of shame and self-loathing initially, but now… she welcomed them. She hadn’t realised it, but she loved the feeling of Nightmare Moon’s huge, corrupted form inside her tight, pathetic little body. Why had she ever tried to deny it?

Returning to the matter at hand, she began to work her cock even faster, wrapping her tongue sensually around every pulsating vein she could find, rubbing the meat she couldn’t hold in her throat slowly and deliberately with her hooves. She caressed the gigantic, churning balls that hung down below Nightmare Moon’s hind quarters, blind with excitement for the moment she would be drowned in the royal cum within. She also shifted on her hooves, manoeuvring herself so that she now straddled the tentacle that was buried deep within her desperate, hungry womb. She slammed her hips down against the floor, forcing the entire mass into herself in one swift motion. Nightmare Moon stumbled on her hooves, almost overwhelmed by the heavenly feeling it generated within her.

Twilight was now in her element, her throat and belly stretching and shrinking as the two huge masses inside her butted against her walls. Her mind was awash with thoughts of her future with her new Princess, how exciting it would be. She rose and fell onto the tentacle at her pussy, pounding it relentlessly. It slid in and out of her with ease, now lubricated with the vast amounts of excess pre-cum that it had already sprayed into its willing victim. Twilight looked up into the eyes of her mistress. Nightmare Moon’s eyes were looked oddly vacant, as every muscle in her body had begun to shake and twitch with anticipation.

Suddenly Nightmare flung her weight forwards, crashing her fore-hooves into the wall that Twilight leant on, sending cracks radiating out over the brickwork. She had hilted herself in Twilight’s throat again, cracking Twilight’s nose against her rusted shackle. The tentacle, too, forced itself as deep into Twilight as it could possibly go, before beginning to spasm wildly. Nightmare Moon was cumming.

The wave of cum was like nothing Twilight had ever seen, or felt. The loads she had been given in the past by her mentor and by her father were immediately forgotten as 1000 years of lust fired into her stomach and womb. It shot down her throat with incredible velocity, bulging and stretching her stomach profusely. It ballooned out with wild speed, smacking into the cobble below and continuing to expand. As it did she could feel her womb filling with the same euphoric heat, as the tentacle pumped vast quantities of spunk into her slathering twat. She was being filled from both ends, her body stretching and gurgling as it continued to fill at an alarming rate. By the time the flow finally ceased, she looked like she had had a baby dragon pumped into her lucky womb.

She could feel the tentacle slowly dissipating, as it transformed from the solid mass back into the same celestial essence it had always been. The absence left her pussy feeling tragically empty, as it gaped around the member that had once been there. She also felt her mistress slowly going soft in her mouth. Her cock shrank inch by inch, as it reverted back into its sheath. With a slow and audible pop, it withdrew from Twilight’s raw throat and pulled itself out past her lips. As it continued to shrink Twilight wrapped her hooves around Nightmare Moon’s now flaccid cock, rubbing and pulling at it, desperate to bring it to full mast again.

Nightmare Moon looked down at her slave inquisitively, before slowly releasing the leash that bound the two together. Twilight flopped to the floor, exhausted, wallowing in a deep pool of semen that surrounded her. But she didn’t try to run. Nightmare Moon knew she had her on her side.

“Good girl, Twilight. 1000 years I waited for someone to pleasure me, and then you come along. You, with your kindness of heart, your good intentions, your sweet little mouth. All mine now. I think you deserve to be a part of my brood. You’ll be giving birth to the first of my empire soon, and then you get the pleasure of raising them to be a proud member of my army. Strong in body, mind and seed.”

Her victory speech was cut off by the sound of multiple ponies galloping towards them down the castle corridor.

“Ah saw her gettin’ teleported in here by that spell! We gotta find her!”

“Don’t worry Twilight, we’re coming to save you!”

Nightmare Moon pulled Twilight to her hooves by her side, and turned her to face the doorway. “Now, I hope you’re ready, young one. We are going to have to introduce your friends to our little brood. First these five, and then all of Equestria.”

She looked up to the decrepit castle window, the moon lingering above them in the dark night sky. “Those pathetic little ponies will tremble at my hooves once more, as I claim my rightful place on the throne, with my breeders by my side. I hope you are ready for me, Celestia.”
