Following Celestia's stumbling upon the scene left by her sister after a 'fruitful' night, she gains a curiosity in exactly what makes Luna tick, so to speak.

Celestia has always known her sister to be a strange being. Strange being an understatement. Celestia herself, just as any mare does, has her 'fantasies', but when juxtaposed with what Luna considers enjoyable, the things she considers to be extreme seem like foals play. After seeing what her sister is capable of doing within the realm of reality, Celestia gains a curiosity in what Luna might be able to do within the dreams she weaves.

Reading the Prequel isn't really necessary.

Heed The Darkness, Sister.

Still, the ever so annoying estrus season dragged on. Luckily, however; it was winding down. Most of those away at the coastal resorts and retreats had begun to return, and the male component to the Royal Guard was set to return to active duty within the next week. That was all fine and dandy, but the hormones were still there, especially for Celestia.

Luna had gone off a few nights ago and broken her chastity, and broken quite a few laws while she was at it. The aftermath was quite brutal, but intriguing all at the same time. Celestia shivered as she remembered the poor stallion's body. When one sees things revolting, one is accustomed to turning their eyes away; the opposite happened to Celestia. She couldn't look away from the damage Luna had so lovingly inflicted.

Of Course, Celestia wasn't a barbarian like Luna, and had no desire to do such a thing. She was a civilized mare; her fantasies were of gentle ropes binding limbs, loving taps on the rear, passionate kisses, nibbles, and above all; slow, deep penetration. She failed to comprehend the things that went on in her sister's mind. That said, she didn't condemn the things her sister found... 'attractive', if one could even associate the word 'attractive' with disemboweling one's partner and breaking their neck.

Despite this, Celestia found herself extremely interested in what exactly Luna's fantasies were like. In her old age, it was quite difficult for something to surprise her. When she had discovered Luna sleeping comfortably beside the mangled, blood-soaked corpse of her 'sire', she hadn't truly felt shock, surprise, or even anger. Disappointment? Indeed. Especially since this had been the fourth time she had stumbled upon the unruly aftermath of the events.

Luckily, Luna had discovered a way of fulfilling her needs in the physical realm without causing harm to a truly sentient being with a loving family. The unfortunate bat that had fluttered past her door and unwillingly become subject to a spell turning him into quite the impressive stallion may have had a bat family somewhere out in the world, but at least Celestia didn't have to spend an entire day brainstorming ways to cover up the loss of a poor guard.

"You are strangely quiet this supper, dear sister." observed Luna from the other end of the private dining table, drawing Celestia's eyes up.

"Just... thinking of something."

Luna watched as Celestia's magic stabbed her fork into the salad that accompanied her main course.

"Might I inquire what is on your mind?"

Celestia looked up again, letting out a little groan of reluctance. "Well, I don't quite know if you'd be okay with it."

Luna raised a brow, sitting up straighter. "You have my attention."

Celestia cleared her throat. "So, I know that you have basically 0 interest in ever conducting a dream where you and I are together..."

Luna rolled her eyes. "Whatever you're going to ask-"

"Ah ah, wait; let me explain."

Luna sat back.

"I've been quite interested with the things you find... exciting. While I find it revolting, and I do think as your sister I should at least submit you to some sort of a therapist... I find it intriguing."

Luna remained quiet, her mind clearly working to find out what Celestia's move was.

"So... alright, first off, in your dreams, when you do the things you do... does the other party actually feel pain?"

"I do not know. I have never once brought another into a fantasy with me. My mates are pure projections."

"If you were to do things to me, would it hurt?"

Luna's brow raised, her head cocking to the side. "Are you suggesting that I weave a dream where you are subject to my tastes?"

Celestia rubbed her neck. "Yes, I am."

"I am horribly confused, sister. You have always been quite... condemning of my tastes, and yet now you sit before me asking to be subject to them."

"I know, it's a bit of a flip-flop. I'm just very curious. And, after all, it would be a dream, so at the end, it wouldn't matter!"

"You are totally, one hundred percent sure that you'd like for me to... treat you?"

"I mean, if you don't have any problems with it..."

Celestia's head was aimed down, her gaze going through her brow and her voice held low. Luna hummed in thought.

"Tis far different to have my ways with a stallion of my crafting than my own sister. I... hardly wish to see you sprawled before me..."

"You've never once fantasized about doing things to me?" inquired Celestia in a hopeful tone.

"Nay, never once."

Suddenly, the little smile Celestia wore curled into a grin. "Has Nightmare Moon ever fantasized about doing things to me?"

Luna's posture stiffened. "She was not real. She did not have her own 'tastes', for she could not have them."

Celestia hummed. "But if she did, she'd probably want to do something to me, right?"

Luna pressed her hoof into her face. "To clarify; you wish for me to craft a dream where I, in the form I do so detest, am allowed to do as I please with your body?"

"Basically."

Luna tapped her chin, her eyes browsing Celestia's figure for a moment. "It would prove to be a very unique experience."

Celestia nodded, giving a hopeful smile. "Indeed, it would! You know well that I enjoy being on the submissive side of things, as well."

"That you do, weakling."

"Weakling, hm? I suppose I would last through twice the punishment you put that poor stallion through a few nights ago."

Luna grinned, raising a brow. "Was that a challenge?"

"Oh, it might have been."

Luna gave a throaty chuckle, narrowing her eyes. "You have accepted a challenge far too grand for your capabilities, sister."

"We'll see tonight, won't we?"

"I think we shall. Do not retire to your chambers; come to mine."

"And... why should I do that?"

"I can ensure you do not scream through your sleep."

The non-joking matter of Luna's speech brought a tinge of worry to Celestia's mind. "Alright, then..."

Through the silence of the night, Celestia's own heartbeat pounded loudly in her ears. She lay on her back, wings spread, in Luna's large blue bed, its new, clean sheets soft against her fur. If she wasn't so nervous she might have been able to find its comfortable nature inviting. She had been lying there for a fair ten minutes and had still not fallen asleep. Luna sat at the other end of the bed, waiting for her bigger sister to slip into sleep's warm embrace so she may too climb in next to her and drift off to her realm of dreams.

"For having been so confident, you are quite nervous." quietly commented Luna, her eyes shut.

"It's hard to fall asleep with you sitting right there. I'm just distracted."

"And nervous."

Celestia sighed in defeat. "And a little nervous."

"Might I put you to sleep?"

Celestia looked over to Luna, her eyes still shut.

"Like, make me go to sleep with a spell?"

Luna nodded.

"It'd be the fastest thing..." shrugged Celestia.

"So be it."

Luna's horn came to life, her eyes finally opening as she gave Celestia a little smile.

"Sweet dreams."
~~~
Through the void of the night a pair of turquoise, slit pupil eyes glared at her. A pair of eyes quite familiar, and a pair that, under 'standard' circumstances would have tied a knot in her stomach and brought a cloud of dread over her mind. Now, as she looked back at them, she could hardly feel anxiety or fright. Anticipation was more what she felt. And... maybe a tiny bit of anxiety. The eyes began moving to the side, and Celestia tracked them, their eye contact breaking as that pair of eyes explored Celestia's body. Her night vision must be quite impressive for her to see anything within the void of... whatever room they occupied.

Suddenly, numerous candles around the room came to life, revealing a perfect replica of Luna's private quarters. Celestia looked around at the mildly romantic setting before meeting Nightmare Moon's gaze, her eyebrows raising as she browsed over the black figure before her. What stood a few hoof-lengths away was not the Nightmare Moon she knew, for this being was a stallion. He stood only a bit taller than Celestia, his mane and tail still wispy and astral, yet less lengthy. His body was sculpted finer than any other stallion she had laid eyes upon. His rear legs were thick with muscle, and thick, healthy veins stuck out against his inky coat.

She yelped as his magic lifted her from her hooves, placing her on her back in a blue, cushiony bed. Her rear legs dangled lazily in the air providing him with a totally unobstructed view of the goods between her haunches. Their eyes locked for a second before Celestia looked between Nightmare's legs, a black and pink splotched erection hanging heavily between his legs. Her tongue slithered from her lips, her eyes remaining on the member as he stepped forward, the long shaft gently swishing side to side.

Already, she could feel a heat between her legs. Her body already ached to feel his member within her walls. He put his hooves on either side of Celestia's haunches, craning his head down and pressing his muzzle against her well-developed teats. She shivered as his tongue gently lapped against her hard nipples, little moans slipping past her pursed lips as he circled the little nibs with the very tip of his tongue. He opened his mouth, gently scraping a fang along one of her teats.

She cried out as his fangs dug into the soft flesh of her teat, her body wiggling side to side as the pain of the bite surprised her. His magic took her forelegs and hind legs, holding them still as he increased the pressure of his bite. She clenched her teeth, rolling her head side to side. She could feel his tongue lapping up the blood that had begun to leak from the four little punctures. The fangs came free, causing Celestia to sigh out in relief. She craned her head up, gazing into the slits of his azure orbs. His smile almost made her heart melt.

He moved his head down, pushing his nose into the already wet lips of her marehood. Her body tensed, her breath pausing as she felt his hot tongue grace her lips. His mouth opened wide as he cupped her entire marehood, driving his tongue into her walls. She shivered as she felt his sharp fangs grinding and scratching at the soft skin near her pussy, fear slithering in with pleasure as she anticipated the fangs to puncture her once more. As the seconds flashed by, and his tongue continued working, the fangs never came to bear, only pleasure leaking into her nerves from her crotch.

A gently blue aurora surrounded his horn, an incredibly tingling, almost electric sensation shooting through her body as he toyed with her clitoris, causing her to yelp out in ecstasy. She squirmed gently at the magic binding her limbs, each breath being accompanied with a little gasp or moan. Her entire body felt warm and her vision seemed to swim as incredible pleasure built within. His magic took over, now encompassing her lips and slithering into her walls, only bringing more pleasure.

Her back arched hard as he sent pulses of energy through his castings, her crotch seeming to be on fire with the tingling sensations. His tongue and fangs backed off, his head craning back as he watched his own magic working. His eyes came to hers, their eye-contact barely able to be maintained as Celestia kept rolling her head back, fidgeting and pulling at her restraints. Her gasps had turned to hard, panting exhalations, and her moans had turned to yelps and whinnies of giddy enjoyment.

His magic slithered down her crotch, tickling the little space between her anus and lips before finally moving to her puffy rim, both parts of her marehood now being pleasured by this electric weaving of magic. She was no longer able to keep her head up or her eyes open. Speech was impossible. In fact, she wasn't even able to think of anything other than the burning, ticklish joy roaring through her crotch. With each second she could feel herself coming closer and closer to an orgasm.

Both of his hooves were placed at either sides of her marehood as they began to tenderly massage the soft fur of her inner thighs, his head coming down as he touched his lips to her stomach. He slithered his tongue down her belly to her teats, licking gingerly at the little drips of blood seeping from the four punctures he had inflicted.

He let go of her back legs, letting them shiver hard as she neared an orgasm. He pushed his magic further, penetrating deeper into her anus and pussy. Her hind legs clamped against the sides of his chest as she cried out, back arching, entire body shivering as she climaxed. He only pushed harder, increasing the intensity of his magic and moving deeper, causing her to yell out louder. Her cry deteriorated into a mixture of whines and pants as he pushed her over the edge, the burning pleasure from her orgasm turning almost painful as he relentlessly massaged her marehood.

Her body seemed to scream at her, her mind wishing for the pleasure to finally stop, but it kept coming. Finally the onslaught stopped, causing her body to fall limp, her chest heaving as she gasped for air. Moans leaked past her heavy breaths as the once intense fire of sex burned down to a simmer, her head finally lifting from the bed as her eyes met his. He stepped forward, bringing their muzzles close, but not delivering a kiss. He took her bottom lip with a fang, only holding it with enough pressure to keep her from slipping free.

She flinched, whining as his sharp fangs pierced into the velvety flesh, drawing a little bit of blood. He released her lip, her head recoiling back as she pressed at the wound with her tongue in an attempt to quell the pain from the little puncture, a copper taste filling her mouth. Lovingly, he placed a kiss on her bloodied lips, Celestia returning this kiss. She felt his magic encompass her horn, holding her head firmly in place as he broke the kiss, staring at her for a moment before moving down, clamping his maw around the higher part of her throat.

She shivered, feeling the sharp tips of his teeth poking at her flesh. Slowly, the pressure of his bite increased, Celestia wincing as she felt his fangs finally poke into her skin. She clenched her teeth, drawing in a sharp breath as she resisted the urge to squirm or yell out. With his fangs still dug into her neck, he crouched down, lying on top of her and pressing his hot erection between their bellies. He began twisting his head, pulling and gnawing at the flesh in his mouth, eliciting little cries from Celestia. She could hear her own skin tearing and popping, pain stinging through her nerves as he destroyed the once pristine flesh of her neck.

Her back legs kicked in retaliation, her body wiggling beneath his as she struggled in futility to free herself. His rod throbbed against her stomach as her movements rubbed his cock against her, causing it to pulse periodically. She yelped as he pulled his head back, bringing her neck with it as he tore more and more of her skin. He released his fangs from her, causing her to gasp as she felt a hot wetness leaking down her neck. He shot her a little grin before beginning to lap up the blood pouring profusely from the wounds he inflicted, causing her to whimper at the painful sensation of his tongue dragging along the mangled flesh.

His head came up, his aggressive lips contacted with her reluctant lips, his head turning to the side and his tongue forcing her mouth open. He forced her into a passionate engagement, the taste of his saliva and her blood mixing on her tongue as he toyed around inside, the tip of his tongue tickling the roof of her mouth. She struggled to pull her head back, the aurora firmly grasping her horn never budging, keeping her in place as he continued feeling around.

Finally, he broke the engagement, his magic working to clamp her mouth shut to hold the mixture of saliva and blood within. Hastily, he stood up, rotating around and yanking her head down, aligning her mouth and throat. His erect, pink and black member hung before her muzzle, her eyes locked with its flared, throbbing tip. In a quick, fluid motion, he forced her mouth wide open, pushing his tip into her wet, warm mouth, keeping the mix of fluids inside. Her eyes began watering as he thrust forward, pushing his huge tip to the back of her throat, causing her to gag. The blood and saliva in her mouth too pushed at the furthest part of her throat, making breathing impossible. Her chest convulsed as she failed to pull in air through her nostrils, each second his member pushing further and further.

His hard, huffing breaths filled the air as he moved with haste, the vibrations of her gagging tingling his shaft as it slid through her warm, soaking throat. He took a little pause, preparing himself as he gave one hard thrust, his cock totally filling her throat, causing it to bulge out. The act brought forth a loud groan of ecstasy as his flared tip stretched her throat, still cutting off any air from passing through. Still, she tried to resist the magic holding her limbs. She thrashed at her restraints, her body wiggling side to side, and her head trying to free itself from the aurora holding it in place. Her actions only caused more gagging as his member followed the curve of her throat anytime she moved.

Her body screamed to be free. Her mind was covered by a blanket of fear, a horrendous ache writhing in her chest. Keeping her eyes open had become too much of a labor, and tears now freely streamed down her cheeks. Suddenly, a force took hold of her neck, constricting her throat with great pressure as he thrust faster, his magic pressing her flesh around his cock. The force increased in pressure, his movements increasing in speed as his cock pulsed with each push, any little bit of oxygen once making its way to her brain now gone.

Her temples throbbed with pressure, her chest feeling as if an entire house sat upon it. Her struggling had stopped entirely, her limbs had become a little limp in their restraints, and her chest no longer convulsed in a poor attempt to bring in air. His grunts had become distant and quiet, the pain throughout her body seeming to fall away a little. Still, he moved on, each push causing his balls to slap against her muzzle, leaving them with a healthy bit of saliva coating them, as the fluid now dripped steadily from her lips with each thrust. Her hooves began to tingle, every one of her limbs now going totally limp, along with her head. Relentlessly, he pounded on, the wet sounds caused by his member violating her throat no longer audible to her ears.

A loud rumble was all that filled her ears, and her cheeks and temples felt as if they would burst from some strange, internal pressure. The tingle that had started at her hooves now encompassed each of her legs entirely, her wings now too feeling that all-encompassing sensation. Thinking had become difficult, and pain seemed entirely gone, what little aches she did feel being pin pricks compared to moments ago. Her black vision began filling with silver, dancing shapes and dots, the fear and anguish screaming in her thoughts no longer able to bring themselves up. She could barely even feel his cock pressing through her neck, or the magic pressing her soft flesh inward.

It felt as if she were falling asleep. That moment of half-consciousness right before the mind shuts itself off for the night. Moving was impossible, and her mind could only think to try and stay awake for a little longer. That thought quickly disappeared, the flashing dots of silver in her vision too fading away as she drifted off to sleep, her body feeling warm and happy.

Then, her eyes fluttered open as a horrific pain stabbed through her horn. Quickly, her eyes opened wide, her chest rising quickly as she drew in a hard breath, a mixture of cum, saliva, and fresh blood pouring into her lungs as opposed to air. She coughed violently, her body shaking and chest heaving as the thick, stringy liquids filling her mouth and throat were rejected, most of it leaving with only enough force to drip down her muzzle onto her cheeks. As sense flooded back so did pain; her chest, stomach, neck, and horn screaming at her as if they were set ablaze. Her eyes began to resume their function, and she could see she now lay sideways on the floor near the bed, her head pressed firmly to the floor. She could see his black, fetlocked hooves a short distance from her face, one of them tainted by blood.

A white object clinked to the hard floor before her face, her eyes widening and lips quivering as she instantly recognized the object. There sat her long horn, blood seeping from its shattered end. She let out a hoarse scream, trying to push herself away only to be held firmly by his spells.

"I-I w-want to wake up!!" she screamed, shutting her eyes, her tears being lost in the mix of other fluids on her cheeks.

He knelt down, dragging his tongue through the tears, cum, and saliva on her face. She shivered, her sobs thrashing her body and heaving her chest.

"You gave your mind to me. This world is mine, and mine only." returned his regal, deep voice, his tone having a throaty rumble to it. "You rested in my bed. Your mind holds no leverage over what may occur here."

His head moved down to the blood leaking from the chew marks in her neck, his lips pursing as he drew the crimson into his mouth, twirling his tongue around on the smooth, ripped flesh.

"You shall wake once blood has been truly let. In death, you shall know waking."

Celestia clenched her teeth, her body still shaking as she cried. She could feel the warm blood leaking down the side of her head from where her horn had once been, her eyes opening for a split second to again meet with the removed spire. His aurora retrieved the horn, holding its point below her chin and beginning to push. The spell holding her head in place increased in strength as he forced her horn through the soft flesh of her upper throat, her eyes opening wide as she whined a stifled yell of pain. The horn kept on going, giving one final push as it broke through entirely, tickling the bottom of Celestia's tongue.

An ear-shattering scream left her throat as unimaginable pain seared from the wound, the horn coming free and blood beginning to pour down her neck and into her mouth. Her thrashing only got worse, her body struggling as hard as it possibly could to be free. With her horn still held in his magic, he got up, bringing Celestia back onto the bed, her limply spread wings like white sheets as they lay out from her sides on the blue, soft cushion. Her scream had turned into a periodic moan of agony, each exhalation letting the sound lose. Her struggling had faded into an uncomfortable wiggle, tears still streaming down her cheeks.

She yelped as something stabbed into her stomach. She tried to look up, but his magic held her head in place. She gasped as an electric sensation washed over her entire body, and as it faded, it brought her pain with it. She felt as if she were floating, her limbs tingling and totally lacking of sensation. Her breathing instantly began calming, her eyelids lowering as he allowed her head to drop to the bed. What she could still feel, however; was the trickles of blood running down her neck, chin, and cheeks. Her tongue curiously poked at the hole in the bottom of her mouth, a fresher, more potent flavor of blood returning to her tongue. The exposed muscle and flesh was extremely soft and smooth, and she found herself almost unable to stop from probing at the hole.

A new, wonderful sensation was allowed to shoot through her body; the feeling of his soaking, hard tip pushing at her lips. She groaned, weakly lifting her head, their gazes meeting as he slowly penetrated her willing marehood. He offered a gentle, almost loving smile, one that seemed to tell her that things would be better from now on. She broke their eye contact, looking down her body to see a hole in her stomach, blood slowly trickling down her fur from the wound he had caused with her own horn. She looked further, barely able to make out his stallionhood as it pushed into her walls.

She gasped as he thrust hard, his balls slapping space between her pussy and anus and his tip hitting the very far end of her walls. She let her head fall back again, her limbs limp in his magical restraints as he pounded away, his speed allowed by the mixture of fluids already coating his member and the fact she had been soaking from the start. She closed her eyes, focusing on the pleasure and letting her fears subside, tingles of ecstasy zapping through her numbed body. She bit her lip as his steady, quick pace continued, rocking her body on the bed. To her surprise, the magic holding her front hooves to her chest and rear legs in the air disappeared, her legs lazily flopping to his sides. She moved her forelegs a bit, enjoyed the freedom he had offered, but she didn't try escaping. He knew she wouldn't. Judging by her pleasured moans and lip biting, he could safely assume she was enjoying herself.

His pace changed, slowing a bit as he drew his rod back to where only the tip remained penetrated, then driving all the way forward to the deepest point he could possibly reach. Each of his long, hard thrusts brought a loud groan of pure enjoyment from Celestia, her lips curled into a wide smile and her bloodied mouth hung open. She shivered as one of his hooves came up to push and massage the blood-soaked fur of her stomach, his loving gesture causing her to let out a stifled giggle.

Again, he adjusted his movements, pausing for only a moment as he wrapped both front legs around her body, their chests connecting as he resumed. The gentle friction between their bodies and the warmth of his embrace bringing her more excitement. His tongue lovingly dragged along the bloody fur on her neck, the lick starting at her collar and working all the way up to the hole in her throat. Celestia moved her head, bringing his lips to hers as she engaged him in a passionate kiss. Their heads twisted to the side, tongues dancing together in the place between their lips.

Through their kiss sang moans of pleasure from both parties, her crotch burning with sexual enjoyment as he continued to hit that far end of her soaked pussy. He broke the kiss, moaning and giving one final thrust as he climaxed, Celestia feeling his warmth spread into her walls with each strong pulse. Little thrusts accompanied his squirts as he filled her to the brim, warm cum spilling down her cheeks and to the bed below. He released her body from his hooves, planting them firmly on the bed as he backed up, pulling out, the exit of his tip sending a healthy flow of sticky fluid down Celestia's rear. He huffed out an exhausted breath, his head hung low. Celestia clamped his sides between her hind legs, causing him to look up at her. They shared a smile, Celestia's chest heaving with exhaustion, as well.

She suddenly remembered the circumstances of her existence. She remembered his words, and she remembered the odd fact her sister's mind was what drove the impressive stallion of the night before her. A tinge of dread flowed through her as she looked away from his gaze, drawing a breath in.

"Sister..." she began, somewhat shaky. "you can end this now. I-I don't need to see... everything."

He craned his head down, glaring at her. "How are you so sure your sister is here?"

"I-I know you are."

He hummed. "It matters not if I am truly your sister or a figment of your mind's creation. What matters is this shall end how it always ends." He leaned close, their muzzles nearly touching. "There is never an alternate ending. As life itself ends in death; so shall this night."

Celestia shivered as his tongue slithered along her muzzle, eventually dragging up to the base of her broken horn as he began lapping up the blood that leaked from the shattered spire. She yelped as his tongue contacted the exposed and horribly sensitive material within the broken base of her horn, her forelegs coming up and pushing at his chest to try and remove him. Suddenly, she realized how weak she was becoming. Her hooves tingled as they were moved from her chest, and what force she could apply to him was barely enough to move his large figure. He brought his head back, looking at her for a moment before stepping back, her entire body becoming surrounded with an aurora of magic as she was placed on her stomach, her forelegs and hind leg tucked comfortably beneath her.

Upon being upright, her head began getting lighter and little stars started to twinkle around in her sight. Her blood-leaking wounds were beginning to take their toll. His magic forced her head down to the bed, turning it to where she was able to look back and see him standing above her, her neck being turned in a fashion that restricted her breathing quite a bit. His magic brought up her bloodied horn, her eyes following it as it was floated point-down above her neck. Before she could scream at him, the horn came down, stabbing entirely through her throat, impaling itself firmly in her flesh. Her eyes went wide, her mouth opening as she let out a raspy cry of fear. Blood began filling her mouth from her throat, causing her to cough and gag. Her chest heaved as she tried to pull in air, barely any making it through.

He left the horn impaled within her as he turned his attention to her back, his hoof coming up from the bed as he worked a spell to grant himself a gleaming, long blade built onto the side of a blue steel shoe. She winced as the blade punctured her upper back, right next to her spine. Viciously, he began sawing and pulling to drag the blade down her back, Celestia unable to move from the horrifying sensation of the long blade going through her flesh. He finally stopped a short distance from her tail, blood pouring at an incredible rate from the cut that spanned from the base of her wings to her very lower back. The blade disappeared, his now nude hoof being joined by the other as they were planted on either side of the huge slice. He pushed down with great force, spreading the cut open, exposing her bloody spine and the softer meat within.

He brought his head down, turning it to the side as he tried to get at her spine with his fangs. Celestia's teeth clenched, tears flowing from her tightly shut eyes as he worked to free more of her spine from her flesh. She felt his fangs clamp and gnaw at her raw spine as he was finally able to separate it from her back, her eyes unable to move away as she watched him pull and twist, her entire body pulling with his movements. He pressed firmly at her back one last time, holding her down as he put all his might into one hard yank, her spine breaking in two with an audible pop as nerves and cartilage separated, eliciting a scream of terror from Celestia. Now, she tried to escape; she tried pulling herself away or standing up, but nothing came from her rear end. She could only wiggle her forelegs and struggle against the magic that held her head in place, not a single sensation or movement came from her back legs.

Her breaths were quick and heavy, her stifled struggles becoming more fearful and sporadic. She could still feel his teeth grinding and chewing at the exposed bone hanging from her back, her entire top side warm and ticklish from the streams of blood leaking down her fur. More and more he pulled on what part of her spine was still attached to her upper body, cracks and snaps ringing through her body to her ears as bone and nerve separated. He finally removed enough of her spine to reach the beginning of the cut at the base of her now useless wings. They hung limply from her sides, her once pure white feathers tarnished with crimson. He finally let go of her spine, letting the length of raw, wet bone drop back into the blood-filled cavern of her back. His magic encompassed her once more, rolling her useless body to the side, her stiff back legs remaining involuntarily tucked to her underside.

Their eyes met for a single moment as he stepped forward, Celestia looking away as she whimpered out a sob. What parts of her body she could feel were tingly and lightweight from blood loss, and her vision was nearly as useless as her back legs. Her mouth continued to fill with hot blood from within her throat, but she could barely find the strength to cough and spit to remove the liquid. Her breathing was stifled and quick, little snorts or gurgles occasionally coming from her mouth as air struggled to pass the blood and horn filling her throat. Again, with futility, she tried moving her back legs. The only thing she could truly feel anymore was the terrified shaking of her upper body, her forelegs, and her left wing, which occasionally fluttered in an uncontrolled spasm. She opened her heavy eyelids, looking back to see that her stomach had been splayed open, the reds and yellows of her intestines dimly shining in the candle light.

Unable to look away, she watched as he turned his head down, viciously pulling more and more of her gut free from her body, her flesh beginning to sag inwards. She closed her eyes again, sobbing quietly and shaking as she listened to the wetness of her own innards falling to the floor beside the bed. She didn't bother opening her eyes as she was rolled onto her back, zero sensation coming from her rear as he began to rut her again, her body gently rocking back and forth as he thrust away. A spell yanked her head upright, causing her to wince as the horn still stabbed through her throat twisted and turned within. Her gaze met with his sneering grin, his blood-soaked mouth and fangs forming a smile as he thrust his hard rod through the tight, bloody walls of her anus, his tip entering the gutless cavity at the end of his long, hard pumps. She looked down, watching in mute terror as his pink and black flared tip appeared through what little tunnel remained of her intestines.

Her body was surrounded by a magical aurora, the weaving of magic he had cast to numb her body coming undone, instantly eliciting a jagged, gurgling scream from Celestia as burning, unthinkable pain shot through what nerves remained connected. The little shreds of strength she still possessed were used in a useless attempt to free herself from him, his magic not bothering to hold any other part of her body but her head as he never ceased his assault on her. Her ears were filled with the wet sounds of sex along with his grunts and moans, his movements quickening as he neared an orgasm. Their eyes locked again as an aurora of magic surrounded the white horn impaling her neck, giving it a hard twist to widen the huge hole in her throat. Her eyes shot wide, her tongue sticking out a tiny bit as he continued twisting, the loud rips and cracks of flesh and muscle being torn echoing through her senses.

He let out a long moan, his thrusting slowing as he climaxed, forcing Celestia to watch as his member throbbed within her anus, squirting strings of cum into the bloody puddle within her stomach cavity. His entire body shivered, pleasure coursing through him as each little thrust caused another pulse, and each pulse throwing more ejaculate into her. His magic released her, letting her head fall limp to the bed, as she no longer held the strength to keep her neck taught. Her eyelids were half open, blood now pouring from the wide tears in her throat and gurgling up through her mouth. He slid his member free from her ruined anus, huffing a pleasured breath before stepping up on the bed, standing over her and lowering his head to hers. He gave her a little grin as his magic encompassed her head for the last time, twisting and pulling hard to break her neck.

Celestia jolted awake within Luna's embrace, her sister's grip instantly tightening to restrain her. Luna tucked her chin into the crook of Celestia's neck, shushing as the much larger Alicorn's struggles ceased, her mind finally crashing to reality.

"You are fine, sister. Calm down; t'was a dream." Luna cooed calmly, causing Celestia's head to droop as she huffed out a breath.

"I'm awake... I'm awake..." she looked to her hind legs, moving them about in relief. She pulled a hoof from beneath Luna's hug, quickly tapping it along her neck and up to her horn. "I'm... awake."

Celestia's breath shuddered, her entire body still shivering with terror as she whimpered a stifled cry, causing Luna to gently rock her side to side.

"W-Why didn't you w-wake me up?"

"T'was your idea."

"B-But... I-I told you! I said I didn't want to see everything!"

"I was not there to hear your words, sister."

Celestia pulled herself forward, looking at Luna. "W-What? But... you were the one..."

"Nay. She was a projection of my mind into yours. I had no control over her. I... could not bring myself to act upon you myself. My apologies."

Celestia stammered in confusion. "Wha- she?! There was a stallion! A... a male Nightmare Moon!"

Luna cocked her head. "I cast a mare, yet you saw a stallion?"

"Y-Yes!" Celestia wiggled herself free, taking a deep breath as she scooted away from Luna on the bed. "It was a male Nightmare Moon."

"You saw a stallion..." Luna tapped her chin. "This is extremely interesting. Your mind altered the projections I cast to... fit preference? This is something I did not foresee happening. This is all quite new to me, sister."

Celestia sighed, rubbing her face with her hooves. "Well, it's going to stay new, because this is the last time. Keep this in your dreams. Don't ever do this to another living being. Ever. Do you understand me?"

"Aye; my intent is with your wish." Luna looked over her still terrified sister for a moment, remembering the little checks she had done upon waking. "Exactly what did he do to you, Celestia? As I stated, I was not within your mind to see."

Celestia's jaw quivered, her eyes falling and posture slouching. "Must I tell you?"

"It would be helpful. Your mind seemed to have a lot of influence on the projection."

Celestia sighed. "He... broke my horn, a-and stabbed it into my neck. He, uh... he ripped out my s-spine... and disemboweled me."

"That is all?"

"N-No... there was a lot more. That... was just the worst of it."

"Did he show compassion? Was the intercourse loving?"

Celestia could almost see the notebook and pen in Luna's mind jotting down notes. "Yes... even when he was, well, tearing my body apart... he was loving, I suppose."

"He capitalized on your greatest fears; loss of body function and loss of magic. I know well you fear losing your horn the most."

"You can add having my own horn driven into my throat to that list."

Luna hummed. "Creative. Certainly something I myself have never done."

"You're so... horribly casual about this."

"Tis my own desires, albeit very altered and distorted from their origins. Besides, there is much to study and learn from this experience. By facing your fears in the world of sleep, you can far better prepare yourself for not if, but when they happen in the land of the waking."

Celestia stared at her sister for a time, seeing the truth in her wisdom. She chuckled nervously, standing up from the bed and giving her wings a little flutter.

"I suppose, in that aspect, you're right. But... I think I'll wait a while before I subject myself to that again."

"Pain is commonplace. It is unavoidable. It will happen no matter how hard we avoid it. There is no use in running from it. Welcome it, and learn how to turn it into pleasure." Luna smiled. "Hard to torture somepony if they enjoy the torture."

Celestia blinked. "You're weird."

"Indeed."

She sighed, looking out the window of Luna's bedroom. "It's morning, isn't it?"

"Indeed."

"Well, then I'm going off to start the day."

"And I shall be off to bed soon."

There was a little pause as they shared a look, Celestia huffing as she went for the door.

"Have a good sleep, Luna."

"I always do."
