Crystal Prep High School, October 31st; Halloween, 20 Years Ago: 11:50 pm

The two females giggled deviously as they hid away in the school library loft still able to hear the screams and laughs of the students and staff as they scrambled around trying to find the culprits behind the insidious prank that had taken place during the Halloween dance. There was to be a crowning of a king and queen of the dance and as usual with popularity contests it was a race between the most popular boys and girls in school, among the females running there was Cookie Crumble, Spoiled Milk, Twilight Velvet and of course Celestia and everyone had run a fair race as expected however the top runner for King, Filthy Rich had managed to bribe the judges enough to where he and his date Spoiled Milk were the victors and not Celestia and her date Sombra.

However two girls in particular didn't quite like that and so they'd decided if they were going to play tricks and trick those they cared about out of what was rightfully theirs then they'd play a trick to make sure they knew their place and learn their place they had. By the end of it all Filthy Rich had ended up a sniveling mess after being exposed to images of his worst nightmare...all his money burning. And as for spoiled milk? Well let's just say her namesake matches her current situation since during her crowning as she was to bust open the full moon pinata that was supposed to be full of candy but instead got gallons of actual spoiled milk spilling all over her and needless to say the sight was not pretty and the literal spoiled brat was going on a warpath looking for those responsible.

They knew they were safe however, no one knew about this secret area in the loft except for them, Celestia & Sombra. Speaking of those two they wondered how they were handling everything? To ensure there was actual justice they'd also exposed Filthy and Spoiled for cheating via a hidden note to the current principal. It was a special night for them both, they had shared many things, childhood memories both good and bad, they were both the younger sibling to an elder, they both came from a well off family but were seen as 'the black sheep' or the outcasts, they'd both had sex with their elder siblings even...however this day was something special that they shared. A birthday and it was a fact both of them were born at night and on the same night, it was strange that the two were sisters but it felt so however they preferred soulmates.

They'd gotten comfortable on air mattress they'd brought into the room, the only source of light being the pale moonlight of the full moon as it leaked into the room through the circular window that lay in the wall.

"So you think Tia and Sommi are mad?" Luna asked with a toothy grin

"Oh please Lu-Lu we did them a favor; besides that little cunt Spoiled needed to be taught a lesson; though you'd be curious who is really the woman, shes the one on a warpath while her rich boy-toy is sobbing like a wittle baby" Miasma laughed and held her sides still trying to get her giggle-fit to calm down.

"Yeah, I mean did you hear how loud they screamed?! Damn near thought I'd go deaf..." Luna chuckled and shook her head. "Guess I'll have to thank Discord for supplying us with all that spoiled chocolate milk..."

They'd both taken pride and joy in their mischievous little trick and were ready to settle down and have the fun they'd been waiting to have all night aside from causing screams throughout the halls.

"Well while they run around screaming their heads off; how about we make a few screams of our own hm my little moonlight?" Miasma gave Luna a sultry smile and winked at her.

"I'd be delighted...I haven't heard you scream all night long; while I do adore your laugh..." Luna scooted closed and reached her hand to Miasma's crotch and gave a rub and made the inky black skinned woman shudder and coo. "It's your screams I love the most Mia...and now here in the shadows under the pale moonlight as the clock nears the midnight hour..." Luna whispered lustfully in Miasma's ear, grazing her teeth along the skin of her ear teasingly as she rubbed the girls pussy through her one piece leotard that lay behind her black and violet witch cloak. "I intend to make you scream and shout my name to the stars..."

Miasma shuddered and moaned, a tint of pink crept over her shadowy skinned cheeks as her purple painted lips hung open in a 'o' as she moaned and cooed in delight under Luna's icy cold but delicate touch. Her generous double D chest rose and fell as her nipples clearly hardened underneath her clothing. Luna's hand rubbed up and down and she got wetter and wetter and nibbled on her lower lip in a small attempt to hide her moans and screams of pleasure only to tease Luna and make her kick up her efforts so she wouldn't be able to hide them from her. Grinning at this display Luna launched forward, her jet black painted lips colliding with Miasma's purple ones and she snatched at her tongue right away and suckled on it and moaned into her lovers mouth as their breasts docked together. Luna's hands crept around Miasma's middle and crept up to her breasts and let them free of the leotard that had kept them confined and of course her beloved wore no bra.

Luna would use her mouth to keep Miasma's open so that her moans couldn't be hidden and she made them louder by pinching and tugging at the girls nipple making her squeal in a mixture of pleasure and pain but clearly there was more of the latter than the former. Grinning a vixen like grin she'd release her nipple and cease her kiss and look her beloved in her violet purple eyes.

"Naughty girl; no bra today?" Luna teased flicking her nipple

"Hmhm when is that different from any other day? I tolerate those uniforms so I think not wearing those chest chokers is justified..."

"And no panties either? My, my my just itching to be as close to your birthday suit as possible aren't you Mia?"

"I don't see you complaining; mmmm in fact I can smell you from here"

"Well I think it's time we got to one of us screaming our heads off...who got the most screams this time?" Luna asked

"Me; remember how many of those freshman I made cry? Yeah the screams came first..." Miasma grinned darkly

"Ooooh and screams of the children are worth 20 points each and that was an entire room...dammit all" Luna pouted a little

"Hehehe better luck next year...now be a good girl-"

"You know I'm anything but-" Luna grinned deviously

"Oh how silly of me yes; be a very bad girl...and take your medicine; I want my screams to shatter these crystal walls." Her eyes flashed a shadowy purple light as she handed Luna a vile with a purplish black liquid in it. "This is a very special batch; I've been experimenting more with more fertile subjects...the girls have brought me so much good nectar to work with." Miasma said with a sinister smile.

"Well...here's to the night..." Luna uncapped the vile with her teeth and slammed the entire thing back. Licking her lips of any that dripped down her lips she'd shudder and groan feeling a heated feeling in her chest and her crotch. Her skin turned black, her eyes turned dragon like, her teeth sharpened and her hair took on an ethereal starry shade. Her chest grew a cup size now comparable to tits found on a milf, and between her legs from her pussy would sprout an iron hard erection but her pussy remained and this made Miasma lick her lips in anticipation.

"Mmm much bigger than the last time; true what they say isn't it? Black is best..." She giggled and extended her foot forward, her stockings were black and purple stripped and were made of silk. Rubbing her foot on Luna's cock up and down she'd extend her other foot and stroke it with both her feet and grin savagely at Luna. She loved to play with and tease her, to see that pretty little face contort with pleasure as she worked her magic. "So my little nightmare...ready to make me scream now?" She asked in a haughty tone.

Luna was gone, there was only The nightmare now; her nightmare; Nightmare Moon. She advanced on Miasma throwing the woman to the bed on her back making her squeal and yelp in delight with how forceful her lover was being only out of excitement since she was always like this when she took her medicine. She felt her ice cold hands grab at her breasts and squeeze and caress them, and her eyes would flutter and her thoughts would go hazy as she prepared for her nightmare to take her into a world of lust and screams and when the clock neared midnight with only a few seconds to spare Luna whispered in Miasma's ear.

"Scream for me..." Luna leaned down and bit her ear roughly and drew blood and thrust her hips forward sheathing her dick in her lovers cave and it was then she heard her ear piercing screams of pleasure and they were screams that echoed throughout the walls of the Crystal Prep library and they were the only screams that could be told from the screams of terror coming from the rest of the school.

"Such a lovely scene isn't it Luna? So happy we both we're...until you abandoned our dream..."

Miasma's voice rang from the ether as Luna watched the scene before her, this old memory, a dream that Luna had often...a time before things had gone wrong, a time before her beloved had fallen too far into the shadows, a time when she would have willingly followed her to the depths a Hell if it meant she could feel loved and accepted.

"This...That...That isn't me anymore Mia; please...s-stop this madness" Luna whimpered in her dreamscape as in the real world her body could do nothing to stop Miasma's touch nor her enchantments.

"Stop? Tsk, tsk, tsk; sorry Luna but you know once the ritual beings there is no stopping...you and your sister only delayed it...but it will continue...and tonight? It'll be all the stronger! I've even inspired a new generation of Shadowbolts to be my followers; it took some coaxing but they trembled before my magic and joined....of course I made sure they all had a blissful experience before I allowed them a proper rebirth..."

"Y-You still torment innocence even in death?"

"Oh please those girls I claimed were far from innocent, they were absolutely FILTHY with darkness; I was impressed to say the least and how deliciously ironic that these girls are all related to our original club members; just goes to show you this is destined to happen!"

"My sister stopped you last time...you will be stopped this time too" Luna trembled as she tried to remain strong.

"Oh really? And who is going to stop me now hm? Those rainbow color freaks you've all got running around? Hahaha! Don't make me laugh, they're no match for me...they've only faced rouge magic of their own creation and a couple of sirens...they've NEVER faced anything like me...remember around me all light dies...all hope fades away...all that is warm turns cold...and by the end of the night you'll all drown in your nightmares and embrace the darkness with me and then everyone will be able to embrace their dreams just like we always wanted!"

"So as long as the sun shines and there are dreamer of the day...the darkness will always fade in fear of the light" Luna said almost sage like and simply chuckled.

"I'm going to enjoy breaking you again...it seems 20 years has made you forget your place!"

**************************************

Celestia's Office

"Enjoying the show Celly? Hm you look a little tense Tia; whats wrong? Ooze got your mouth?"

"L-Leave Tia...a-alone..." Luna tried her best to say and not moan.

"Oh now that would just be rude Lu-Lu; why would I want to leave poor Tia out of our fun? After all my big brother isn't here to pleasure her...Oh and he says Hello from Hell by the way Tia..."

"What are you talking abo-"

"I set my brother free; had a few errands to run before coming to see all of you...this all started with him after all..."

"You've truly become a demon!"

"I know right? Amazing isn't it? Now Tia...just how should we take care of you...hm choice, choice...lets see....I could fuck Luna right in front of you but you've seen that before, forcing you to rape her wouldn't be any fun since you'd just be sickeningly comforting...hm...AH HA! I know...wodahsreov la poessia!"

Miasma spoke the incantation and her astral form would leave the body she'd previously taken which then fell to the ground dead, its life force completely drained and the corpse left a withered husk. Her phantom form was a inky black shadow that bore the girls likeness and she grinned at Luna.

"Impressive no? I can overshadow the bodies of mortals and make their forms my own however as you can see doing it for too long kills whoever I am attached to...and now you're body is mi-aaaaaargh!" Miasma hissed as she tried take over Luna's body but was blocked by a glowing blue light that came from the pendant around her neck. "So that enchantment is still there hm? Clever girl Celestia...and what an annoyance that little bitch still is; still defying me even long after being dead! Hmph, no matter it may sting but I will have you! You won't stop me this time!" Miasma used her magic to lift the pendant from around the neck of the corpse she'd just had and it glowed a black and purple light and the shining blue light on Luna would fade as it was sucked into the amulet.

"There we go...not all of it is gone but is just dark enough in you now that I can make myself comfy...just like old times!" Miasma shot forward and crept her way into luna chest between her breasts and Luna's body became coated in a purple and black aura and when she came out she'd grown longer hair, her eyes were that of stars and pure shadow, her pitch black skin also had ancient magic symbols of a purple shade along her arms, a cresent moon symbol right above her breasts, and her entire aura had become cold like the darkness that had now taken her...her costume was now who she was on the outside again...Nightmare Moon was reborn.

Looking over herself she'd grin and laugh devilishly and throw her head back in evil glee.

"This darkness...this body...it feels so good; so embracing, so familiar after 20 long years of rest! Hmhmh whats the matter Tia? You look as if you'd just seen a ghost...oh wait, thats right!" She shot an evil look at Celestia and licked her lips. "Now time for fun...I can see it's been quite some time for you both, according to Lu-Lu's memories you haven't gotten any cock since Sombra? Awwww how sweet of you to somewhat honor my big brothers memory...well how about I help remind you of him? You may remember this little spell from you're 16th birthday, after all that was the day you let Sombra finally plow that sunshine ass of yours; Oooo your screams that day were just delightful...Lets see how well I measure up..."

Miasma spoke through Luna, their voices mixed together to form a new one that had a balanced level of malice, seduction and pure evil; her mere aura sent the entire room cold, her eyes bore into Celestia's soul and when she reached down and cupped Celestia's face with her hand, her touch made Celestia feel like death was actually touching her and she'd only ever come close to death once and that was the last time she'd been faced with Miasma. As she caressed her face she tore off the goo that kept her mouth shut causing Celestia to gasp for air and cough. Celestia hadn't even noticed Miasma chug down a vile of that purple and black goo or the iron hard dick that sprout in place of her pussy since she was too busy coughing her lungs up but when she finally looked up her eyes went wide with fear and Miasma was relishing in it.

"Oh how I adore that look! I bet that's how you looked at Sombra's dick the first time you saw it; what do you think? I'm bigger aren't I? Fun fact I killed him while fucking him, gotta say he hasn't lost his touch in these 20 long years, his semen was so rich, I used it to make this very special batch and the best part? I finally managed to make a batch that enables fertility, so if you don't die after this; you'll have to live with the shame of baring your sisters demonic baby cause we both know you don't have it in you to abort...no you'd just give them up, that's what you did what your first born isn't it Tia? Hmph have to say the little brat was lucky!"

If there was one thing Celestia hated for anyone to mention even by accident it was the mentioning of her daughter. Her little girl that she had to give away when she was only 18 years old after having gotten frisky with Sombra one too many times. She never wanted to give her away, she never wanted to abandon her only child but with the situation as it was back then she had no other choice and had to give the girl up for adoption and hoped and prayed every single day that she was in a good home and was leading a better life...it helped somewhat that in a roundabout sort of way...her daughter was not that far away and she knew in her heart of hearts that if anyone was going to be the one to stop Miasma and her darkness...it was her because she had the one thing Miasma didn't...friendship. A semblance of a smile crept onto Celestia's face and she could see how that visibly angered Miasma as she knew she hated when her 'victims' weren't afraid or intimidated.

"You're right...she is lucky because...and I know she and her friends will be the ones to stop you....so do as you wish...I've not lost my touch over these 20 years either...You won't break me Miasma" Celestia spat and uttered the woman's name with disdain.

The woman chuckled and grabbed Celestia by her hair and shoved her iron hard cock against her cheek and slapped her with it and grinned a devious sneer.

"No 'sister' I am not Miasma...nor am I your precious little Luna...no...our union is at last as it should be and as it always should have been...we are now truly one with each other; at last my precious moonlight has embraced the shadow as she long should have and together we will shall bring blissful nightmares to ALL of Canterlot City..." The woman sneered evilly at Celestia, her voice dripping with lustful evil intent.

"W-What are you talking about? W-What have you done?!" Celestia barked but then felt her face slapped again but the throbbing appendage.

"I've simply had my children of the night put in place the instruments of my revenge...soon all of their screams and the nightmares to come will ensure my reign!"

"W-What...are you?!" Celestia was beginning to feel the fear, a yellow mist leaking from her body and gathering into the woman's amulet around her neck and she began to glow.

She grinned a toothy grin continued to rub her cock on the side of Celestia's face. "Me? Why I'm your worst nightmare of course! I...Am Nightmare Nebula! And tonight, I eclipse the sun so that my night...and all its blissful nightmares shall last FOREVER! Now...ordinarily I'd ask you to scream for me...put you've run your mouth off too me one too many times Celly and you always had quite a bit to say about us when we were young...so I think it's time we put that cake and cock loving mouth of yours to good use!"

Her evil and seductive sneer persisted and she thrust her hips forward sheathing her cock in the tightness and warm of Celestia's mouth and made her take it to the hilt and she relished in seeing Celestia's eyes go wide with fear, pain, pleasure and surprise. Having fused with Luna and already knowing what she knew about Celestia she knew that Celestia loved a few things from cake to teaching...but on the kinkier side of things Celestia was a size queen and liked her men dark and the only man that fit that profile was Miasma's big brother Sombra Shade, Celestia's childhood friend and high school and college sweetheart, the relationship having ended in their senior year of college, it wasn't exactly pretty but years later they'd long since gotten passed it and had thought to invite him to this party tonight however it would seem Celestia now knew the real reason why he wasn't answering her calls...rest in peace beloved.

Celestia's tears leaked tears as Nebula continued to fuck her face, gripping her hair roughly she thrust forward and she clutched Celestia's right breast with the other hand. It wasn't like she wasn't used to rough treatment, the way Sombra was often rough with her in bed was proof of that, Hell even how Luna would be when they had their romps in bed in high school and she would get rough she'd enjoyed it; however Miasma...She wasn't the same girl that Celestia and Luna knew in their youth; before the dark phase began, Celestia tried her best to remember the once kind and innocent ink skinned girl with purple hair and eyes and a smile that shined like the evening stars but all she saw now was a monster and all she felt was forced pleasure and an aching pain in her heart.

Celestia's grunts and groans of resistance, her gagging and the sloppy, nasty and undignified sounds she made as her meat rod thrust in and out of her mouth roughly, the look of fear in her eyes, the way her body paint make up ran as her tears fell; all of it was pure bliss to Nebula, it fed it, it empowered it, the lust, the power, the fear; all of it was making her stronger and she wanted more, needed more!

"Such a good little cock sucker aren't you? Did my brother face fuck you like this? Huh? Did he shove his big hard black dick deep in your whore mouth? Hm? Did he Sun-Butt?! Don't worry, don't be afraid; in fact no...be afraid...be very afraid! Because I'm gonna make you crave me! Make you want me! Your sister is mine and I know you want her back; want her Celly? Hm? Do you want us sister?" Nebula snarled as she continued to fuck Celestia's face only hearing Celestia's grunts and gargles as her response. Grinning she'd rip her cock from her mouth and slap her with it again. "Speak up sister; do you want us?"

"G-Give...m-me back...my...Luna...." Celestia said in a whimper as she coughed. "I want my Luna back..."

"Be a good little girl and come and get her then; if you think you still have it in you! You've aged Celly de-mmmmmmmmm my my my eager to have your sweet luna back a-aren't yo-oooooooh fuck!" Nebula gasped and shuddered in delight almost letting out a small scream as Celestia licked her cock from bottom to the tip and swirled her tongue around the tip and then took the entire thing into her mouth, she was a full 10 inches and Celestia managed to take every damn inch and this time she didn't gag. When she finally came back up for air she'd swirl her tongue on the tip again and she'd look up at Nebula in defiance and Nebula found this exciting and infuriating.

"I-I'm not scared of you...I WILL have my sister back and if I means I have to fuck you out of her...so be it..." Celestia eyed the woman with lustful disdain as she stroked her cock roughly with a hand, it didn't seem she could feel much pain and if she did she was getting off on it; she'd need to be careful, this was still Luna's body and that's the only thing that made this tolerable by any means. Celestia continued to think to herself.

'Sister, if you are in there, keep the light close dear sister...Tia is right here, the rest after this will be up for harmony to decide'

Celestia said nothing else and simply let her libido take her where it hadn't taken her in over 20 years. She remembered those days back at Crystal Prep, while she was a model student and among the most popular if not the most popular...who was she kidding she was the most popular girl in school and she didn't need to be an elite bitch like the rest of the girls in school. Celestia was kind, caring, loving, understanding, smart, graceful and well respected by everyone for the most part in some way and they all had a level of fear for her because Sombra was her boyfriend and Sombra by looks alone was enough to strike fear into the hearts of children; Luna never liked him but in vise versa Celestia never really liked his little sister but they all tolerated each other because they had similar roles; Celestia and Sombra being the elder siblings and Luna & Miasma being the younger siblings.

Celestia and Sombra had begun just as friends when they all had met when they were about six years old and Celestia had quickly developed a crush on Sombra and had even effectively asked him out by the time they reached 7th grade. She will admit to having given her virginity to him when they got to their freshmen year in high school but hey teenagers will be teenagers and Celestia loved Sombra and him only so it wasn't like she was a slut or anything sleeping around with whomever she wished unlike his sister. However Celestia did get hot and heavy with Sombra A LOT and they'd had sex in school more than once, Hell she even remembers fucking him in the principals office once when she got in trouble for one of Luna and Miasma's pranks and Sombra had to bail her out.

The facesets of pleasure and kink weren't unknown to Celestia; she'd explored quite a bit with Sombra and Luna; she'd even had a few swings with Ms.Cheerilee, Harshwhinny and even Mrs.Mash in her college days; Luna wasn't around in those days and thus she only had comfort in Sombra and friends she managed to make around campus and of course as college kids are bound to do she'd gotten in her fun, which was one of the reasons why she and Sombra broke up, the other reason being he was taking the whole 'being the king of the school' thing way to far. She remembered how she used to pleasure him, how she used to pleasure her sister, how she'd pleasured those other women in college(I may or may not invite Mrs. Mash to my office sometimes for 'Meetings about her sons behavior') and she'd use these to give this...this thing, the pleasure and sensation needed to bleed whatever light she could into her so that her sister would remain for the rainboom's to save.

Gathering what saliva she could in her mouth she spat on the long black appendage as if disgusted with it and lubed it further than it already was and forced Nebula against the nearby wall with a thud and kept a firm grip on her dick and stroked it still, keeping fiery determined eyes on Nebula and Nebula looked down on her with a haughty smile.

"That's good Celly; just like old times hm? Is it good? Hm? You like it right Tia? The way you're jacking it I bet you just can't stop thinking about my brothers dick! The look on his face when I came to his door was euphoric, I could swear I saw his soul leave his body! His fear was so delicious I just sucked him dry of it...just like your about to do now right? Hm you little cockgobbling slut?!"

"Fuck you; your not my sister, your not my fallen king; I'm doing this for those I love...not because I love you..." Celestia said and going against her own advice, put the woman's member in her mouth which then caused Nebula to throw her head back and release a loud but shuddering moan and scream of delight as Celestia deepthroated her like she loved the dick that was in her mouth, gobbling and guzzling it down her throat without struggle, breathing through her nose as she bobbed her head up and down, back and forth, slobbering all over it; bubbles of her saliva pooling around her lips as she gave long deep strokes and sucks and switched between deep and short throat.

"F-Fu-oh Fucking Hell! C-Could've fooled us! Ooooo look at you go! Cocklestia still has it in her I see! hahahahahahahah! Mmmm I see where Lu-Lu got her talent fro-oooommmmmmm! Oh shit that's the stuff! Y-Yes! Oooooh yes! I-It's been so long since we've felt this feeling, this rush! OOoooh my fucking g-good glorious shadows! That right bitch! Take it!" Nebula roared as she kept in time thrusting as Celestia gave her the most soul shaking blowjob of her existence, Luna was fantastic as using her mouth and she'd felt the pleasure of a blowjob before thanks to her magic however never before had she felt it like this; all those sluts from around school, Luna...none of them compared to Celestia, her lips were like the purest velvet, her throat was a long, warm, wet tunnel and Celestia had zero gag reflex, and she was skilled with her tongue in a way she'd only thought possible of that weird Pink girl she'd seen at the party earlier.

After giving her cock the greatest mouth washing of its life she'd rip it from her mouth and spit on it again and grinned up at Nebula, sneering a false pleasant smile that was no doubt smug too. Celestia then freed her breasts from her costume, a very healthy set of 40 DD's sat upon her chest and she wrapped Nebula's cock between them and squished it between them and began to stroke up and down slowly and swirl her tongue upon the tip as she sandwiched her meat stick between her hefty chest.

"F-F-F-F-F-OH-OH FU-FU-FU-OH FUCKING HELL YOU LITTLE SLUT YES Y-YOU'RE GO-GONNA MAKE ME-!" Nebula couldn't even finish her sentence before she felt her climax shoot through her like a bullet and she pumped her cock between Celestia's tits and screamed when Celestia took the tip in her mouth and snaked her tongue into her urethra and swirled it around making her howl as her load blasted into her mouth, making her cheeks puff up like she was a chipmunk and when Nebula felt she was full, she'd rip her cock from her mouth and jerk her cock off vigorously in Celestia's face shooting the rest of her creamy hot load in the woman's face and all over her large breasts making quite the sloppy mess of her.

Celestia took everything she could swallow and kept it in her mouth and took what she was given to the face and chest, looking up at Nebula she'd see the woman sneering deviously at her.

"Swallow your treat Tia; you always did like the frosting most on the cake didn't you?"

Scowling at her Celestia complied still and chewed the cum in her mouth, opening and closing her mouth and gargling the sloppy white goo in her mouth for Nebula to see and then she swallowed every last drop. Her hands rested on her chest and smeared the cum along them as the rest that missed her chest dripped to the floor.

"That's a good little cum-slut cocklestia; you certainly haven't lost your touch...but now it's time to really hear you scream..."

Grinning she'd grab Celestia and prop her on the desk and leaned over her, their breasts pillowing together as Nebula grabbed her cock and lined up with Celestia's waiting cunt, bumping the head against clit to make her squeal and jump.

"Now...Do me a favor Tia dear sister?..." Nebula leaned in and whispered savagely in Celestia's ear. "SCREAM FOR ME!"

Nebula shouted as she thrust her hips forward sheathing her cock in the tightness of Celestia's pussy; while Miasma would hate to admit it, Celestia's pussy was almost better than Luna's; it was so warm, almost hot, it was so tight even for having given birth to a child, it was incredibly wet which made for ease entry and Celestia; every time she would pant moan or scream; she got tighter and it felt like her pussy was strangling her cock in a vice and didn't want to let Nebula go almost as if she were trying to suck the soul out of her. Celestia felt it, the fullness, the stretching, the rough feeling of getting plowed; it'd been 20 years since she'd had anything remotely this big that was real, the last real man she'd slept with was Sombra and since then had only used toys or had women for weekends when school wasn't her priority.

Her brain nearly short circuited from the raw rushes of pleasure and pain she felt, she didn't want to make it look like she was enjoy this because on the surface she wasn't...but deep, deep down...she was and she would be eternally ashamed of herself. She continued to imagine it was Luna or Sombra that was fucking her right now so that it would make it more pleasurable however it was difficult because for her part Nebula looked equal parts Sombra, Miasma and Luna just entirely female. Celestia was trying to not scream, not give in and crack; but the pleasure was too much, too great; the way she thrust and gyrated her hips, the way she played with her clit as she fucked her, the way she fondled gripped and slapped her tits while she went to town; all of it was sending Celestia into a frenzy of lust she wasn't sure she could...or wanted to escape.

She'd howl, scream, holler, wail, shout & moan in ecstasy fueled bliss as Nebula continued to hammer away at her pussy without mercy or relent and it was the sweetest music to Nebula's ears.

"That's right bitch! Scream! Scream and shout your pleasures to the rooftops! Let the cosmos hear your cries of bliss; awaken the dead with your wails of pleasure! You love it don't you? You love how much I fuck your cunt don't you Celly? You love getting this precious little flower of yours destroyed by this big black dick don't you?!" When she saw Celestia wasn't speaking up she'd slap her across the face and grip her cheeks roughly digging her nails into her face. "ANSWER ME!"

All her thoughts swirled, her emotions swelled, her lust was in control, she was lost now; she'd have to simply wait for the rainbow to shine through and set her sister free now but she knew that at the very least she could help them along. She knew her method of stopping Miasma that worked last time might not work this time but it was worth a try. The sun shaped amulet around her own neck shined a faint glow and it coursed through her body and gathered at her core. Her trap was set and now all that was needed was to spring it. She'd comply with Nebula's words and answer her.

"Y-ES YES! I LOVE IT! FUCK ME MORE! FILL MY PUSSY WITH THAT BIG DARK ROD! G-GIVE IT TOO ME! F-FUCK ME SISTER! FUCK ME!"

Nebula would comply, her lust having taken over as well, her eyes flooded with a purple light as she pounded away at Celestia's pussy without stopping. She felt her load churning again and she'd continue to look Celestia in the face as she fucked her, relishing in the thought that she'd broken her and now she'd finish things and move on to exact her revenge, by the time the clock struck midnight she'd reign as goddess of the night forever! Her thrusts got harder and deeper and when she located Celestia's G-spot and she unleashed the loudest scream to date it was like a shot of pure Ecstasy through her sister as she hammered her hips so hard she brought about her climax without any warning and unleashed a torrent of cum inside Celestia's pussy, the light gathered at the woman's stomach fading when she did so and lightly flashing not Nebula's stomach but Nebula had't noticed, literally blind with lust.

"There we are...now your one with the shadows; welcome to the dark side Tia...we've been waiting for you..."

Nebula said in a whisper that was almost sweet as she kissed Celestia on the lips and ripped her cock from her pussy and allowed the cum that didn't shoot into her womb to leak and ooze out onto the desk and floor. With a wave of her magic, Nebula conjured up her costume again and put her hood on and moved to leave the room and glanced a look back at Celestia.

"Now if you'll excuse me Celly; the night is young and we've got many more screams to make...and don't think your little 'rainbows' can stop me, my children of the night are going to show them true bliss...and they too will soon know the power of the shadows"

Miasma walked out of the room, now having a physical body she didn't have to walk through walls or anything anymore bu she could if she wanted to but she felt a level of satisfaction walking out and leaving Celestia a cum stained mess like she'd always dreamed of doing. Now that she'd exacted the second part of her revenge, it was time to carry out the final stages; her children of the night would turn the rainbow dark and she'd rule over all as Mistress of the Night.

Magic has been in the human world longer than Celestia and Luna have lead their students to believe and now it falls to the elements of harmony to repeat history and save Luna and the world from a fate worse than death.
