Gaining Back Control



The day had begin to settle down now, turning towards its evening with the sun slowly lowering itself over the horizon. From the sun’s fading light, stars and dark hues of blues and purples began to cascade the sky. Star lights began to flicker and glow, with the moon beginning to take its place where the sun once was.
The endless cycle that was meant to be, from here on forever more. So why did she feel like that would change? What was this deep… odd feeling that soon, her life will change? Something bad? Something good? SHe could not foresee. 
A sigh left her, which sounded more like a growl as she stepped away from her balcony and down to her room. The large spacious room, build for twenty ponies, carried the glow of mane, casting bright flickering shadows from the various items in her room. From the desk holding her papers and pens, to the odd items she had collected throughout the centuries. Many were given from her beloved worshippers and others… from friends and families. 

She decided that now that the day was done, she was to retire into her bed. But before she could, a sharp knock was heard at her door.

“Who is it?” she asked, half irritated that she was being bothered now. The door opened to reveal her assistant to the throne, Raven, who was not affected by her majesty’s harsh tone.
“Forgive the intrusion, but your sister has asked to meet with you.”
She blinked at that, having not heard nor received any indication that her sister was to come by. Then again… she was always playing the mystery mare.
Nodding and waving her off, she informed her assistant. “Send her in, though once she is in, no more interruptions! I am done for the day!” 
Bowing her head, she headed her words.
“Of course, have a good night.” With that, she left and closed the door. Sighing in less annoyance, she made her way to her wash room to at least freshen up before her sister’s arrival. 


Steam left the wash room, with water quickly burning off her coat. Any that dropped onto the floor evaporated with quick ease at the intense heat radiating from her body. 
“I needed that.” she said outloud.
“You always did make coming out of the shower… steaming, sister.” Came a voice from the shadows.
She suppressed a groan and turned to the blackened corner of her room. A faint blue and purple mist with white stars was bare visible through the black but that wasn’t the shadows themselves.
“Ugh… you and your puns!” The other alicorn hissed with disdain. “If I start making ‘moon’ or ‘star’ puns, you get all moody and act like if I’m targeting you personally!”

There was a soft pout before her sister made her way out of the showers and came into the light. Black fur coat encompassed her body, with draconic slit eyes made the brightest part of her body.
“You know, I’ve had maintained a level of maturity over the last thousand years.”
The white alicorn snorted with grin. 
“Yeah right. And I am ‘pink fluffy unicorn dancing on rainbows’,”
This time her sister snorted. 
“You were pink… once and you did have a full fluff chest hair that was good for snuggling.” Teased the midnight alicorn.
Her sister growled. “Alright, enough games. Why are you here… Nightmare Moon!
The black alicorn grinned. “Why so hostile, Daybreaker? Have a rough day in court?”
The flames on Daybreaker grew brighter as did her anger. “Well what would you do if you had a bunch of nobles complaining at you about useless parliaments and the need for more bits!”
“Simple, I show them their place and that just as easily, it can be removed or they can be removed… permanently.”
Daybreaker scoffed and strode towards her sister.
“Not everypony needs to deal with your dark attitude towards them, sister.”
“And not everypony needs to feel your wrath when they annoy you.” Returned Nightmare. “Last I check, pony ashes stain the carpet.”

Daybreaker growled and finally had enough. “Fine, lets forget my day and your day and get back to the matter at hoof. Why are you here?”
Nightmare gave a smile. “That my sister is the question. The question, but something that cannot be answered immediately or it might…”
“JUST GET TO THE POINT!” Daybreaker roared, flames of pure rage erupted from her body. Nightmare was unfazed by this, though seeing her like that… did bring warmth and affection.

Nightmare cleared her throat and walked towards her sister, despite the radiating heat. “Fine. As you know, we are coming up upon the ‘thousandth year’ since the unification of Equestria. We are also coming upon the return of things good and bad!” She then moved away and studied all the relics in her sister’s room. The heat slowly dissipated from her sister, though her anger still remained. “The Crystal Empire’s return, the possible release of ‘Discord’, and perhaps the return of the Pillars.” She stopped upon an old canvas, magically drawn to hold an almost perfect image of herself, her sister and the Pillars. Back then, she went by Luna and her sister had gone by Celestia.
“Yes, I’m aware of this.” Stated Daybreaker. She watched as emotion was drawn on Nightmare, seeing nostalgia and memory fill her face. She too almost felt it but shook it off. “That does not explain why you are here.”

Nightmare moved away from the image and looked towards her sister.
“I am here because I believe we need to have a contingency plan when those days are upon us. We need to have power and a pony on our side that will help us deal with these situations.”

Daybreak cocked an eyebrow. “Your saying that we need a pony that could help us… in power, to prepare for these events?” Nightmare nodded. Daybreaker wanted to laugh at her sister’s invoice, yet the serious and unaltered face she gave, deterred her from outright laughing.
“Your kidding, right?”
Nightmare snorted. “I have no reason to joke to you sister, especially you.” A smile touched her lips. “At least not in the moment.”

Daybreaker gave a moment before responding. “So, then whom do we acquire for this role and how much power are we giving them?” She calmly walked around her sister, trying to find an angle to understand her. “Somepony that we both trust, somepony that we understand and wouldn’t stab us in the back.”
“No pony as such exist, sister.”
“Then?”
Nightmare flashed her sharp teeth. “We make… a pony, worthy of power. We create a lifeform, something we both will  l have a hoof in and bestow them a piece of our power. Imagine, having the strength and rage of the sun, but have the intelligence and wit of the moon. That pony, would be a god!”
“You calling me stupid?” Her sister challenged.

Ignoring her, she pulled out a vial from her eternal mane. Daybreaker saw the large vial, a bluish liquid with sparkles that reminded her of her sister’s night. “This… dear sister is what will bring us our herald.”
Daybreaker studied the vial with small interest but then had a thought. “How do you propose to create a pony and have them drink this… liquid?”
Nightmare turned a bit red at her next explanation. “This is not for the’ pony’ we are creating, sister. This will help us’ create’ the pony we want.” She then looked her sister in the eyes with direct but straight face, sitll having her tint on her cheeks.
“One of us will drink this and give us the… ‘equipment’ to create a pony. Albeit it will be unorthodox, one of us will be the one to give our essence to the other and they in turn will bare the pony in term.”
Silence reigned between them. Daybreaker was looking at her sister with a gaze that seemed distant yet perplexed. Nightmare remained steady, though her mind was waiting for the inevitable…
“YOU WANT US TO CONSUMMATE A FOAL!?!?!?!?” Daybreaker all but blew up. Her flames expanded to enormous proportions. The heat of the flames lit up the whole room and set everything on fire. Most of the non-flammable materials that were protected with magic, instantly ignited. The fire that left her, could be seen from Ponyville from her room. 
Nightmare had raised a protective shield in time to protect her from her sister’s meltdown. Waiting for her sister to relax, she kept it up, even as the room around her was ablaze.

Outside the room, guards and maids stayed away from her door, though a few quickly changed into the fire protection suits, made usually for firefighters. The staff of the castle had a monthly order come in, with upgrades given. 


Daybreaker finally cooled down long enough to were her room had a breathable atmosphere and the temperature was tolerable. Her eyes however remained wide and glowing with fury at her sister, whom wasn’t really affected by it.

Nightmare’s tongue clicked. “Are you done?”
Daybreaker inhaled deeply and exhaled, finally extinguishing her flames… most of them. 
Realizing that none of this had been a ploy or game from her sister, she remained calm but her voice carried some strain. “Tell me… sister. How is this done again?”
Nightmare rolled her eyes before responding.
“This liquid I had one of my scientists cook up, will give one of us, the tools to breed with any female and impregnate them to bare a perfectly healthy foal with no side effects, but all their power.”
Her sister still seemed apprehensive about the idea or the results that lead to it. “And you want us to… impregnate a female with our essence with the vial and bare a foal?” She prayed she misheard the part where it was the two of them and…
“No we impregnate each other or one of us.” She said evenly. 
Again, the idea was so crazy and farfetched, yet it was so unbelievable and odd. 
“And we both become pregnant or one of us?” 
“Either both of us or one of us…”
“Not it!” Exclaimed Daybreaker, quickly.
Nightmare rolled her eyes and sighed. “Right. Either way, if you want to understand how it works, when one of us…”
“Not it!” Daybreaker exclaimed once more.
“...has to take the serum and become the…”
“Im it!” A shit eating grin was on her white muzzle. 
“... I’m…. not that surprised.” Nightmare wrinkled her muzzle in small annoyance, but clicked her tongue and gave a short exhale. “EIther way, since you want to be the one that… gives the seed, I suggest you prepare yourself and become accustomed with your… equipment.”

“Wait, before we do this. Has there been trials done?” A small snarl escaped her. “I won’t take something that has not been tested!”
Nightmare groaned. “Of course its been tested! I wouldn’t bring something that yields no results! We’ve been through trial and error and all the subjects have survived!”

“Survived?” Daybreaker said appalled and in fear. “What do you mean, survived?”
Nightmare cleared her throat. “It is not that the liquid kills them. Rather… inexperienced females have… gone mad with their newfound equipment and become over stimulated with endorphins. They either pass out due to stimulus overdose, ecstasy overload or the dehydration.” Nightmare then blushed once more. “I’ve… tested it myself and have had no side effects. Our alicorn anatomy prevents any flaws. The increased strength, durability, healing, power, speed and more that we naturally inherit, allow us to function above normal ponies.”
Daybreaker snorted. “Of course, we are demi-goddesses. We surpass mortals in every way.”
“Indeed,” Grinned Nightmare before floating the vital over to her. “If we are to create a god, whom better than the demi-goddesses themselves. The foal will have all of our strengths…”
“And our weaknesses.” stated Daybreaker. “If we create a foal, it will be targeted by those who want to de-throne us. As is, we still have assassins every now and then. Even with our security and advanced magic, we still would have to protect the foal and ourselves.”
“True, but think of the power it could impose. Our strengths alone is not to be trifled with. When you and I combine our powers, we defeated the lights of Discord, Tirek, and other foes. With our powers unite upon a single being, we could create an Alicorn with the power to level the planet!” She cackled. “And… it will be under our control. A foal, with the power of a god, being raised by two demi-goddesses, to strike fear into any who opposed us…”
“But do we want to make it as a weapon? Something that… if in turned against us… could kill us with ease?” She shook her head. “Already I can imagine that if one little slip up, goes into the foals head, anything that gives it a reason to turn against us, everything we have accomplished, anything we have ever done, would be un-done.”
Nightmare blinked and saw reasoning in her sister’s words. If the foal was somehow swayed, in anyway to turn against them, they would be destroyed by their own creation and that could destroy their legacies. 
“What do you suggest? Raise the foal to be aggressive or dark like us?”
“No,” stated Daybreaker. “Not like us, quite the opposite.” Her horn flashed and in a blinding light, her form shifted to that of her original. 
Nightmare was staring at her sister’s former alter-ego of a thousand years ago, Celestia. She was prettier now, her mane waving in her trio of colors of light blue, green, and pink. Her coat was pure snow white and she was shorter than her counterpart.
“We raise the foal… as kind and as caring as any other parent would with their foals.” Her voice had returned to a sweet melody and calm carrying tone. Something that Nightmare wouldn’t dare admit outloud that she loved to hear.

Nightmare actually liked her sister in this form. She looked pleasant and beautiful. A smile on her that did not cause fear or agony, but rather a warm feeling in your heart. A long forgotten memory until now.
“Why?” was all Nightmare asked.
“If we want to create a foal that will be our better but not grow up resenting us in anyway, but can still be something our enemies fear, why not raise it with the kind loving care of parents as well as the respect of ponies?” She strutted flawlessly to her sister, until she stood same height with her. “No weakness to exploit us if she loves her parents…”
“And no doubts placed in her mind, if she is influenced in anyway.” Nightmare finished easily. Daybreak… Celestia nodded. 
“What better way than give it a beginning that would ensure us the perfect outcome that we want?”
Nightmare didn’t respond. Instead, her horn lit in a bright blue flash that engulfed her. After the flash disappeared a navy blue mare stood. A moon with a black spot rested on her flanks along with an eternal mane that looked like midnight skies adorned with stars, while being almost a head smaller than her sister.
“So…” Began the sweet voice of Luna. “We treat and raise a foal with kindness and love.” It was a question but came more of a statement. “We raise a foal…” 
“Our foal,” corrected Celestia. “We raise her together and make sure her upbringing is wonderful. She will carry no doubts, no hatred or malice for her parents. We share her equally and with adoration.”
“Her?” asked Luna. “You… think it would be female?”
Celestia chuckled. “Two female alicorns trying to produce a single foal together? The chances of a male are slim to none.”
Her younger sister nodded lightly. “That would make sense.” She looked at the vial in front of her. “So… you wish to be the male and I… carry the foal to term.”
“I think you would make an excellent mother, Lulu.” It was a tease she would tell her way back when they were younger. After they altered their forms, that name was forsaken. Yet, hearing it in so long, it sounded… nice to Luna’s ears.
Celestia grabbed the vial in her own magical golden aura. “If anything, you would still look stunning as a pregnant mare.” She opened the cork on top and inhaled the contents. A distinct smell of sweet lavender, vanilla and a heavy musk of male odor lingered. “What is in this?”
Luna blushed and shook her head. “If you knew, you would reject it. Its best you swallow it whole and let it do its magic.” She paused. “You really think I would still look stunning if I was pregnant?” She asked.
Celestia nodded, giving her a warm smile. “You will remain beautiful, not just to me but to anypony who saw you.” She then pulled the vial close to her mouth. “Bottom’s up.” She tilted the vial up and let it hit her tongue, splashing it with its thick fluid and finishing the vial in a few seconds.
Once the last drop fell, Celestia looked at the vial, smacking her lips at the taste before looking at Luna. “It is… sweet and salty?”
Luna nodded shyly. “Some… male essence was required to create this potion.” She then rubbed her fetlocks against her other leg. “I… had to make sure that it would provide the seed and fluids to deliver it directly and properly to a womb.”
Celestia nodded and waited. “How long does it take.... Oh!”
She felt her body glow and her body spasm, with odd tingles running up and down her spine. She felt her lower abdomen and neithers twitch and stretch. 

Luna watched in wide eyed interest as her sister began to change her form. From between her legs, growth formed as genitals belonging to a stallion formed. A sack of white flesh began to form just above where her clitoris and vulva was. The flesh wrinkled and began to take an almost oval shape albeit with flesh wrinkles. Final it formed to a sheathe were it would hold the ‘tool’ needed for their creation.

Just behind the sheathe but still in front of Celestia’s vulva, lumps heavy with seed began to form and drop in a sack as white as her coat but gray towards the bottom. Her clit had merged with the testicles and with every movement of the swaying nads, sent shrivels of pleasure up and down her spine. Her own marehood also began to slowly tingle with the new addition on her body.

“This… this feel odd, Luna.”
Luna only stared at her sister’s large and new well endowed genitalia. Despite not being aroused… yet, she was quite big with her sheathe probably holding the true size of her new equipment.
“Yes,” she said a bit hazily, still looking at the pair of massive nads her sister held. “It...it takes a bit… to… accustomed to… and…” she trailed off as she saw that just like her own testing, they were swollen and heavy with seed. 
“They feel… tingly and heavy.” she somewhat groaned, shifting on her legs. Her balls swayed and Luna swore she could hear the seed splashing inside of her.
“Luna?” The younger sibling finally snapped out of her lusty haze and focused on her sister. “Sorry, I just… never knew they could be so mesmerizing.”

Celestia raised an eyebrow, seeing that her sister was still focused on her stallion parts. “I thought you said you have tried it before.”
Luna looked away, focusing on her sister’s eyes. “I have. But the mares I have tried them on, were all willing participates already infatuated with me. I thought seeing me male genitalia was just proving me to be the goddess they worshipped.”
Celestia shook her before sighing.
“So then… what happens now?”

Luna blinked. Yes, what did happen now? She just… willy nilly let her sister mount her and fill her with see? Then a year passes and she brings forth their foal? That sounded simple, right?
“I’m… not sure. To be honest, I didn’t plan ahead.” Her nose then scrunched in distaste. She looked down at her body, looking it over. “In truth, being in this form makes me feel less confident and weak.”
Celestia shrugged. “If we want our foal to grow up…”
“At least until we get near its birth,” retorted Luna. “That I remain in my real form.” A quick flash of magic and she returned to her Nightmare Moon look. “I also can’t have any of my subjects thinking I am going weak just because I will carry a foal.” Her deep and powerful voice returned. 
Celestia sighed and she too returned to her normal form with a flash of magic. “I think that ship has passed sister.” Returned Daybreaker’s snarkiness. “If you already had asked your scientist and a few mares to test this elixir to allow motherhood, the idea that they will still fear you has dwindled.”
Nightmare snorted. “My shaman has assured me that while I will be pregnant for the near year, my form will remain cloaked in magic to keep the illusion that remain untouched by carrying a foal.” SHe paused with hesitancy. “They believe I am trying to find a perfect mare worthy of carrying my seed and give me an heir.”

Daybreaker hated the idea of being pregnant, let alone turning soft. That did beg the question.
“Why are you not fighting me on this?” Daybreaker asked. “Why are you not begging that I…” she shuttered lightly at the next words. “Be the one to carry the foal?”
Nightmare swallowed and looked away from her sister.
“I… have wanted a foal now, for decades. After my last blessing that I had for new parents, it was at that moment I had my scientist and shaman cook up something that would give me the foal I wanted.”
Any other time Daybreaker would have heard her sister talk like this, she would have laughed and taunt her sister of her insecurities or petty wants. But since her own flesh and blood came to her, made her switch her forms and back, along with getting all deep and sentimental, perhaps there is a heart worth trying to bring out.
“Why not ask some stallion to mount your and conceded your foal?” She asked, trying to avoid the most obvious answers. 
“Why allow a mortal touch my body and taint it with useless seed that yield no results?”

Daybreaker’s eyes widen. “You… You have courted before?” 
Nightmare snorted. “And you haven’t?”

Daybreaker didn’t answer. Nightmare looked at her and a slow grin began to form on her muzzle. Daybreaker gave her a glare. “Don’t you dare!” She warned. Nightmare flashed her fangs but held her teasing. Clearing her throat, she spoke evenly, though smug dripped from her fangs. 
“I have courted on numerous attempts but no stallion has given me a foal. Our biology is to grand for their simple seed to work.” She used her magic mane to create a visual representation. In it, sperm cells were created using stars while a pale circular planetoid represented the egg. “Ponies… stallions in specific have the potential to impregnate us on a biological scale. The magical aspect however is near impossible.” The sperm cells made their way to the egg and pushed inside. “Now you and I are the most powerful beings on Equss. But it would take powerful magic to impregnate us.” She turned to her sister and held an even stare. “We only have few males that are anywhere near our levels or beyond them.”
Celestia shuttered. “Augh… The goody four shoes, Sombra!”

Nightmare nodded. “He won’t be any use for us until the crystal empire returns. Then there is Discord, Tirek, Grogar, and the others that disappeared are completely out. So that left us… each other.”
“And it… does not bother you that we are sisters?”
Nightmare flashed a grin. “When us that stopped us when we were younger?”
Daybreaker blushed. “We were young, arrogant… and crazy filled alicorns with hormones that wanted to rut every stallion that we could find, including” She shuttered, “Starswirl.”
Nightmare cackled. “You!” she pointed her hoof at her. “Wanted him. “I would have settled for Flash Magnus or Rockhoof! But I also would have wanted Meadowbrook, Somnambula and Mistmane… if she were younger.” She shook her head. “Either way, the matter comes full circle. You and I will consummate and I will bare the foal.”
Daybreaker wanted to avoid yet, the need for her sister to have a foal played at her heart. Their love was on par of that of normal siblings, if you count that they fight with pony lives on hoof, can control the heaves, run their empires through fear or power, normal siblings.
They screamed and yelled at each other, sometimes launch powerful attacks that 
may or may not put pony lives at risk or work with each other on how to kill or destroy their enemies. In the end, they would find someway to communicate peacefully and love each other, without saying the words specifically. After all, a thousand years is to long to be alone.  
“Well then… how should we begin?” asked Daybreaker.

Nightmare blinked and realized she hadn’t prepared her part. “Oh, I have to go into heat and then we can consumate.” 
Silence passed between them and a glare left Daybreaker.
“Well?”
“Well what?”
“Aren’t you going to drink some potion or something to go into heat?”
Nightmare balked. “Why would I drink a vial to go into heat when I can wait until it naturally occurs?”
Daybreaker was beginning to fume at her sister’s words.
“So why did I drink the stupid vial if you were going to go in heat!?” she half roared. 
Nightmare growled in return. “Why did you drink it if I didn’t tell you when we should do it?”
“You practically said that you wanted to gain a foal!”
“I only had the vial in case you said yes! I never said right now! Not to mention the fact that you went all… ‘sentimental’ and reverted back to your ‘prissy’ and ‘nice’ form!”

Daybreaker’s mane and tail fires began to grow. “Ugh! This is so like you to get all moody and the you expect sympathy from everypony around!”
“And it is your fault for not listening to what anypony has to say and judging or taking action before jumping straight head on and blaming others for your mistakes!” Nightmare’s own mane and tail began to create icicles around her body.

Soon both sisters were close to butting head their forms nearly an inch apart and glaring at one another.


Once more outside the doors, maids and servants were preparing themselves for a fight. Though a few had doubts about surviving since the Ice Queen was involved as well.


“To my family, I’m sorry but I don’t think I will make it. The two sisters are going at it and with both of their powers, I might not survive. Please know that I loved you all with my heart and pray that these two psychotic bitches kill each other so that you can live a happier, saver life. Signed, Raven Inkwell.”



The secretary quickly used her magic to send the letter. She sighed and then slipped on her fireproof uniform and heavy visor. Turning behind her, she saw other maids and servants all visibly shaking. Swallowing, she spoke shakily. 
“Whatever happens from here, just know that its been an honor serving alongside you brave mares and stallions.” She raised her hoof to her heart. “May Faust send these whorses to Tartarus and bless us with kinder rulers.” Everypony raised their own hooves to their hearts and agreed with her prayer. Nodding, she moved on with her tasks as well as the others.

Back at the room, the temperature in the room was in the extremes between freezing and melting, as both sister tried to stare down one another.
Finally, Daybreaker relented and eased her flames.
“Fine, lets agree that we agree that we are both at fault and let the matter drop, fair?” Her hoof stuck out in shake. 
Nightmare saw the hoof and allowed her mood to brighten.     
“Agreed.” She struck her sister’s hoof.
They shook.

“Good, now that that is settled, if we are to wait until you are to be in heat, when will this elixir and this… stallionhood last?”
Nightmare bobbed her head left to right. “Twenty four hours… if you don’t use it. Less than that if you use it at a consist rate.” She then added with a small grin. “If you want, we can extinguish that spell by tonight if you choose.”
Somehow, that did make her stallion hood twitch and her lips almost wink in excitement.
“And… you wish for us to fuck each other now… even when you are not in heat?”
“The potion is extremely potent and concentrated. Chances are I won’t need to go into heat in order to be pregnant.”
Daybreaker once more almost fumed, seeing the grin in her sister’s face. “And you didn’t think to mention that before I went off on you?” she asked venomously. 
Nightmare kept her grin but turned away from her sister, walking towards her sister’s bed, while flipping her tail up to reveal a moist and winking pussy. “Who's to say that you getting angry doesn't turn me on?” Secretions fell from her pussy lips, dripping onto the hard concrete floor, leaving a small trail as she made her way to her bed. She got halfway on the bed with her front hooves on it while leaving her lower half standing, giving her sister a great and unprotected view of her pussy.

The reaction had Daybreaker almost red but heavily aroused, as her cock practically popped out of her protective sheath and began to quickly rise. Along with her stallionhood beginning to flare, as did her own cunt, winking and dripping her honey. It wasn’t only until the room had settled with temperature that Daybreaker realized, her sister smelled strongly of heat. Not just that but judging by the heavy winking and juices running down her cunt and thighs, that Nightmare had been aroused for quite a bit and her heat had been going for a bit.
“You… You've planned for this? All of it? You have planned for this since the beginning?” she growled. 
Nightmare had never lost her grin. “Oh… so I may have been leading you on… just to see what you would do.” She shakes her rump at her sister, making her juices swing and fling across the floor. “So… now that you know my plan… my goals. What, dear beloved sister of mine, do you plan to do?”

Daybreaker’s cock was now fully erect, with her cock head fully flared and ready. Her balls swayed with heavy seed and need for release. Her own pussy was gaping for a wanting cock of its own but would have to suffer without it.
Her cock reached up to near her chest, enough to break any normal mare in two. But this cock wasn’t meant for a normal mare, it was meant for her sister, a demi-goddess. A true mare, with lips meant for her cock and to be filled to the brim with her seed without the fear of killing.
She shakily made her way to her sister, each step a stomp, sending vibrations to the floor towards her sister, who cooed and moaned at her sister’s approach. Her cock and balls swayed with each step, eager to be used for the first time, while her own cunt dripped with fluids down her thighs and legs.


Finally Daybreaker’s head was near her sister’s hindlegs, seeing the wide winking puss of her sister, inhaling the deep lavender and earthly smells she naturally secreted. “So…” she began, deeply but calm voice. “This was all a ploy to get me to lose my temper and turn you on?”
Nightmare moaned, feeling the heat of her sister’s breath near her neithers. “Yesssss…” she hissed. 
Daybreaker took a deep inhale, trying to bring in as much of her sister’s smell into her lungs, taking it in and re-memorizing the smell she secretly enjoyed. “You knew… that I would take the vial and swallow it… filled and mixed with stallion cum and… whatever else was in there?”
“Yesssss….” Nightmare moaned as her sister brushed her snout upon her flanks. Daybreaker’s breath teased her sister’s neithers, causing her pussy to wink fast, flare wider and more secretions to fall upon the floor near her bed, creating a puddle.
“You also knew that I might get sentimental, turn back to my old form and make you feel pretty.”
“Hmmm not that far, but it still turned me on when you said I would look beautiful if I was pregnant.” 
Daybreaker growled loudly at her sister’s cunt, the deep growl sending vibrations to the air and making contact with her sister’s lips. “Oooohhhh!”

Daybreaker then pushed her snout on her sister’s lips, finally making contact and feeling heat radiating from her sister’s neithers while feeling her fluids and scent cover her nose and mouth. “And finally,” she moved her mouth through her pussy and making her sister moan loudly at each word. “You wanted for me to finally admitttt…” She emphasied the ‘t’ in the word, sending Nightmare into a shivering state. “That I was at fault and to admit equal?” 
“YESSSSSS!!!!” Nightmare yelled, her vulva almost spewing her honey upon her sister’s face. Daybreaker allowed her sister to squirt her fluids onto her muzzle, flooding her nostrils and mouth with her tasty juices. 
Liquid lavender mint with earthly tones and a hint of sweet, filled her maw with them, while inhaling directly the juices that went into her nostrils and into her lungs, permanently making her sister’s pussy scent the only thing that mattered to her. Her status as a demi-god allowed her to breathe in the fluids without fear of drowning, just mild discomfort.

Finally, her tongue stuck out, lapping at her sister’s quivering lips, drinking and swallowing the cascading fluids that ran from her cunt. Nightmare moaned to the heavens, feeling her sister’s tongue breach her lips and taste her inner core. Her legs shook with delight, almost failing her as pleasure ran through her body like a bolt of lightning. 
Daybreaker’s eyes were closed, as she drank from her sister’s cunt. Her stallionhood begged for it to be inside of those pair of lips. Her own lips twitched and winked at the attention her sister was receiving. The mind was on a high unlike any other, feeling nothing but ecstasy and numb, mostly due to the lack of air, but it was incredibly breathtaking.
Finally,  Daybreaker had enough and pulled away. Her face was drenched in her sister’s pussy juices, dripping onto the large puddle that was on the floor.
“All that… all of this…” she tried to say but came out a bit gargled do to the fluids that inhabited her mouth. She paused talking, closing her mouth and swirling and swishing her sister’s cunt juice in her mouth, enjoying the wonderful flavor before swallowing. “Was so you can get your older sister to fuck your needy little cunt and have a inbred foal?”
“YES!” Nightmare yelled. “What more do you want? I want you to get mad! I want you to growl and yell! But I want you to fuck me hard and knock me up! I want you to fuck me hard and give me a fucking baby!” Daybreaker watched in amusement as her sister talked like a common whorse or a needy slut. Her own neithers were begging for attention, especially her flaring cock, that has been dripping large amounts of pre-cum onto the floor and adding to the puddle.

With a flare of her wings, she jumped her front legs and mounted her sister. The added weight finally sent Nightmare all the way down to her knees on the bed, her head laying on the mattress. Her hind legs shook to keep the added weight, albeit struggling as her sister’s cock was scrapping her ass.

Daybreaker’s dripping face was near Nightmare’s, smearing her own fluids on her face. Nightmare moaned though it came out strained as her sister gently rubbed her cock near her entrance. Daybreaker licked her sister’s face, adding more of her own pussy juice and creating strands of saliva and secretions all over her. She continued this, want Nightmare to be covered, just liker herself.
She teased her sister with her large cock, allowing the tip to gently part the lips before pulling away, earning her a groan in disappointment. Meanwhile she continued to smear her soaked face onto her sister, letting her mouth taste her own juices.
“Know this… little sister!” She gave a long lick from the tip of her snout to her mouth and up to her right eye, forcing it shut with the fluids. “I am very upset that you did all this! I am beyond furious that you made me feel weak” She once more pushed her cock on her lips and spread them, pushing it in, but only about an inch before pulling out, making her sister neigh in dismay and moan in pain. She needed her sister’s cock!
“I am however delighted… to know that I get to be the one that brings a foal into this world with you!” SHe kissed her sister on her side lips, earning a small moan. “Something so wonderful, so amazing… but something so taboo, so vile… what would mother think?”
Nightmare shuttered at the mention of mother, a chill running up her spine. “She would disown us...but I don’t care! As long as I have you, our ponies and a foal to conquer the world with us, I care not!” Daybreaker grinned.
“Oh… playing dangerous… Well then sister. I hope you are ready to suffer! I hope that all this is worth it! Because until that foal comes flying out your cunt, I will fuck you everyday for a year! I fuck you hard, I will fill your cunt, I will make you beg for this cock, every time until the foal is out. And once its out… I fuck another one in you. Again, and again, and again for a thousand years!”

Those words finally sent Nightmare into a orgasmic bliss and she cried out in ecstasy as she came hard. Her pussy spasmed in gushes of cum, covering her sister’s cock in fluids and making it easier for her to slip in. Ceasing the moment of her sister’s orgasm, Daybreaker finally shoved her cock deep into her cunt, cutting off the spray of secretions. Nightmare screamed in delight and finally being penetrated. Her sister didn’t do it slow, she shoved her entire length inside of her cunt, filling her to the brim and fitting all of her cunt all the way up into her womb.  
Her walls clamped tight around her sister’s giant organ, feeling the heartbeat from her. Daybreaker moaned, feeling the tightness of her sister’s tunnel, wrapping around her shaft. It was so hot, enough to match her own pussy. Speaking of, her own pussy also had a micro orgasm as she had shoved her cock into her own sister. 
The taboo, the forbidden fruit and the total and completely alien but welcoming feeling of having a cock, was cosmic levels of ecstasy that no mortal being would be able to handle.

The two stayed there panting, feeling their organs merged and the warmth that radiated from their bodies. Lust filled their minds but love was there as well. Daybreaker never knew she could ever love her evil but intelligent sister more than ever. Nightmare was in the heavens after finally wanting to merge her heart with her sister for a millennium. Something even dreams could come close too.

After a moment of adjusting to their play, Daybreaker pulled out her cock halfway, before shoving it back in hard, earning a grunt and a moan from her sister beneath. Her cock flared and rubbed every inch of her sister’s walls as she pulled back once more, pulling nearly all the way out until she forced it back in. Nightmare jumped at the feeling of cock pushing her forward. Her mouth drooled in delight and her face caked in her own fluids. Her sister just focused on fucking her hard and rough.
Daybreaker repeated the motion, trying to enjoy the wonderful feeling of a shaft inside of a pussy. The thrusts were slow but rough, as she tried to keep a steady feeling of flesh in flesh. She herself moaned, now understanding fully while stallions loved to have their cocks sucked or surrounded by warm holes. Whether it be a pussy hole or an arse hole, it felt wonderful. Her sister may have had suitors or concubines, but her pussy felt extremely tight, meaning no stallion or mare, has fully stretched her sister’s snatch.

Neither dared speak for ruining the moment. Nightmare just allowed her sister to fuck her cunt like a whorse, while Daybreaker treated her like one. Each and every time her cock slipped in and out of Nightmare, was a pleasure reserved for the gods of ponies. The feeling of unfathomable desire that would destroy a normal brain, unable to handle the ecstasy and adrenaline.

Their demi-goddess status, allowed them to enjoy the high ecstasy without the fear of damage in anyway. Their stamina meant they would go on for quite awhile, even after climax. Their strength and durability allowed them to enjoy powerful movements and thrusts that would break normal pony spines. Their healing allowed them to endure pain but turn it into pleasure as they would push beyond normal limits. Their heightened minds allowed them push past normal endorphins and enjoy hours of ecstasy.

Daybreaker was enjoying herself, using her sister’s cunt to satisfy her cock. She wanted to carry this out as long as she could, slowly filling her inside with pre-cum. Nightmare fluids continued to drip out of her cunt, through what little space there was between the thickness of her sister’s organ and the tightening walls.
For roughly ten minutes, Daybreaker and Nightmare fucked in a slow but firm session. They carried it because again, no normal mortals would be able to enjoy this amount of ecstasy and live. The test subjects Nightmare had tried this own either passed out or nearly died from ecstasy overload. If they did survive, they went mad for they became needy sluts and begged for cock. Some had to be locked away for assaulting any males they came in visual contact with. 
Nightmare had never came inside the mare, nor did she fully fuck them for nearly tearing them up inside. The few times she had cum, was when they used hooves, mouth or magic, spraying them with thick amounts of seed. She dared not have any carrying her seed and bringing forth many unwanted foals. Just because normal ponies couldn’t impregnate alicorns, didn’t mean alicorns could impregnate ponies. Chances were high.
Which is why this was the point of amazement. For Nightmare was achieving a dream and a fantasy in one. The dream of finally being pleasured by her sister and the fantasy of becoming a mother.
Her sister would be the father-like figure, while she would carry the wonderful foal in her womb for months. Her teats would fill with milk, almost growing twice the size they are now. Daybreaker would suck on them until the foal came out and then it would suck on her tits, maybe alongside her sister.

The image of herself becoming big got her to release another orgasm, spraying thick squirts of mare cum through the spaces of cock and walls. The edge of the bed was drenched with fluids, almost completely filled and soaked with juices. Daybreaker was puffing now, for she too had came from her own pussy, squirting her cum onto her floors. 
Beneath them both, a layer of fluids had formed and was spreading rapidly across a five foot area. Neither of them cared as their passion and pleasure was all that mattered.

Another ten minutes pass with steady fucking from Daybreaker. She kept slowing down to prevent cumming. Typical stallions want to get quick releases when possible and disregard the pleasure of their significant other, but Daybreaker liked the idea of being on edge. The idea of knowing that if she wanted, she could cum anytime and flood her sister with her fertile seed and impregnate her. But she wanted her sister to suffer. She wanted her to know that she was the oldest, that she was the greatest and that she would always be the one to gain back control!

Nightmare was still not feeling her sister’s seed splash her womb yet. She knew that she was being lead on, to feel some suffering.
“P-P-Please sister! Fill me! I-I-I want your seed!”
Daybreaker growled. “You are n-no one to tell m-me what to do!” She shuddered as her balls began to hurt, knowing that she was dragging this on way longer than needed. “I-I’m in c-control here! Not-t you! You g-get my seed when you admit that-t I’m your b-better! That I-I will always be in c-control! That I am y-your superior! Ugh!” Her balls tighten, her climax was approaching and she was about to bust hard. “I-If you want me s-seed… then beg! B-Beg for it like a-a common whorse! B-Beg for it l-like a starving s-slut! And yell to everypony, f-from my empire to yours! WHO IS IN CONTROL!!!!”

Nightmare yelled to the heavens, using the Royal Canterlot Voice! “You are in control! You are the superior! I'm below you! I am you needy slut! Please fill my cunt with your seed! I want your foals! I want them!”
Crackling with manically, Daybreaker wrapped her fore legs around her sister’s barrel and began to trust like a mad-mare. “You are my sister and you will have my seed! You will bare a god for us all! You will carry as many foals as I want you to! Now… take it ALL!!!!!” Daybreaker roared as she began to piston her cock inside of her sister’s pussy wildly.
Nightmare’s moans turned ecstatic as her pussy clamped and continued to squirt juices in any and all openings around her sister’s hammering cock. Her legs gave out but Daybreaker was quick to use her magic and hold them up, to keep her thrusts deep and fast.
She laughed loudly but growled in delight as her orgasm tore through her cock and began to fire deeply into her sister’s womb. Thick and hot shots of cum fired from her flared tip, the blasts hitting the edge of the womb and began to fill the chamber with seed in seconds.

Nightmare tossed and spasmed as her sister quickly began to fill her body. “Yes! Yes! Please don’t pull out! I want it all!” Daybreaker listened but stayed inside for her own sake, not her sister. She was higher in pleasure right now. Her cock was shooting cum inside her sister while her own pussy was squirting streams of cum and flying out to the floor. She kept her cock jammed inside of her sister, feeling each and every squirt wrack her body.
The sheer amount of alicorn cum began to finally do its job, inflating her sister’s womb and expanding it. Her belly slowly but surely grew in size. Most stallions could claim that they could expand the belly of a mare… or in some cases other stallions, but none would dare boaster what an alicorn cock could do. 
Soon Nightmare already looked like she was pregnant, as her belly grew in size. Daybreaker’s stamina allowed her to keep firing while her ball size allowed a large supply of stallion seed to be fired out. Her balls were shrinking but at this rate they would flood her sister’s womb before emptying out.

A solid minute of cumming from both mares and Nightmare groaned at being filled to the brim as her belly made her look ten months pregnant. Her cunt could not longer take her sister’s seed and was pooling out on tot\ the bed and the floor. 
The white alicorn was moaning as she was coming but realized she ran out of room. Pulling out her cock with quick eased, she had opened the flood gates and allowed all her come to pour out of Nightmare’s pussy. She continued to fire shots of cum across her sister’s flank and tail. She tried to aim for her asshole. Seeing as she never had done it there, even when she tried experimentation, she pushed her cock at her sister’s anus and used her spewing cum as lubricant to gain access.

Nightmare cried in surprised. “Wha-!”
Daybreaker grunted and shoved her spewing cock inside the tail hole, spreading it and flooding the extremely tight cave. She moaned in heavy delight for this was tighter than her sister’s pussy. She pushed deep, allowing more and more come to fill her sister’s secondary hole.
Nightmare’s ecstasy exceeded the discomfort and pain in her rectum. Her sister’s cum still continued to spew her seed, albeit it was slowing down now. 
Daybreaker managed to shove have her cock in her sister’s ass, delivering final thick shots of seed into her ass, adding more weight and size to her belly before her cock dribbled the last amounts of cum from her balls.

Nightmare felt the magic of her sister lift her legs up and pull them on bed. Daybreaker slowly gave a final push into her sister’s ass, earning a grunt from her sister’ before she fell on top of her sister and resting her. The weight helped pushed and shoot the seed out of her sister more, with only the tail hold leaving small trails down.

The two rested on one another, none of them speaking for they were enjoying the aftermath. Daybreaker had gone into a habit of licking at her sister’s face. Nightmare allowed and focused her taint muscles to try and squeeze out any remaining seed from her sister.
Daybreaker’s cock began to weaken and began to shrink back to its hiding area, allowing some seed to seep out of Nightmare’s asshole and add to the matted mattress. Nightmare’s belly finally shrunk enough to look passable, thought she wished she could have had a plug to keep all that wonderful seed inside of her belly.

Half an hour of silence passes between the two, with Daybreaker stopped cleaning her face and Nightmare feeling normal again. Daybreaker rested her head on top of her sister’s. She reached over and began to rub her belly.
“So it is assured then?” she asked quietly.
Nightmare sighed. “It is. I am… pregnant. You gave me your see and I will bare a foal. In a few months, I will grow with life in me.”
Daybreaker rubbed her face on her sister.
“This has truly been your want for a long time now, hasn’t?”

Nightmare closed her eyes, trying to push herself as close as she could to her sister.
“For so long, you and I fought. We always made up but we never said ‘I love you’ to one another. Not since… we took on our new forms.”
“We didn’t want our ponies to look at us with weakness.”
“But why did that stop us from saying ‘I love you’ for almost a thousand years?” Nightmare asked, sadness filling her voice.
Daybreaker didn’t answer. She was afraid too. She was afraid that saying those words to her sister would allow some villain or enemy to exploit it and target her. She was afraid that if anyone saw them loving each other, that they would utilize them and blackmail them. She was afraid that if she allowed her heart to follow her sister’s and allow the taboo to fully come full circle, then she would not be able to lead her ponies.
“I was… afraid.” 
Nightmare wasn’t surprised. She could enter dreams and nightmares. She could see into a pony’s past and know them better than themselves. She knew her sister was afraid for many reasons, but to hear her say it out loud, it finally dawned on her that her sister will always love her. They would always have room in their hearts for each other. No matter their squabbles, no matter their physical need to hit each other.
They would love each other to the very end and this foal, this usual union of flesh and blood, sealed the deal. Her older sister had impregnated her and in almost a year, she would bare her sister’s foal. And they will raise that foal, with love and care that they dared not show to anypony else.
“I… am afraid too.” Nightmare responded. “I was afraid that you would say no. That you would not give me what I wanted. That after a thousand years, me and you doing… anything close to this would disgust you. That you would finally tear at my heart and reject me as your sister.”
Daybreaker tightened her hug on her sister. She kissed her muzzle side. “Not in a thousand years, could I reject you. Not in the next thousand years, would I remotely dislike you.” She then grinned which Nightmare could feel on her snout. “I could call you ‘emo’ or ‘lulu’ or any other name to get you made, but I will always in my heart call you ‘sister’. I wish you and I can say ‘I love you’ more often.”
“After today?” Nightmare asked.

Daybreaker looked at her sister from her eye next to hers. Lifting her head so both of her eys focused on her sister, she gave a pleasant smile. In her Celestia voice, she spoke. “After today, I would wish to call you… lover. I would wish to call you… Luna.” She gave her another kiss on the cheek. “IF you would allow me..”
Nightmare let loose a tear and her Luna voice, she smiled. “I want nothing more.” she sniffed. “I want you there for our foal. To be there and never leave me more than a day and night just with her and I.”

“Never.” spoke Daybreaker. “Faust herself couldn’t keep me away and I will fight and kill any who try it.”

The sister’s finally settled down now, with Daybreaker and Nightmare laying close to one another. Night time was Nightmare’s domain so she remained awake while her sister went to sleep. She looked out her window to see her moon raising high into the sky, all the while she rubbed her belly where she knew that in due time, life would begin and foal would come to the world. A future uncertain with a unique twist, Nightmare Moon knew that her and her sister’s empires would soon merge under a united god… one that would control the very fabric of the world.
