Her sun had crested the horizon line mere minutes ago, Celestia standing lazily at the fringe of the Canterlot Castle's Observatory Tower, a sizable brass telescope resting on its tripod at her side. A warm breeze gave lift to the Princess's weaving mane and tail, the gently moving air giving her cause to crane her head skywards as her nostrils flared, air rushing into her lungs. With a sighing exhale, her head came back down, gaze diverting back to the dark, mountain dotted landscape before her. The past two days had been a time she, and for that matter, her sister, had waited far too long for.
The Night's Ruler had finally returned; albeit in a body far too young for the graceful mare. Having much of her powers weakened by the magic cast to bring her from the cursed form given to herself, the Lunar Princess appeared to be nothing more than a filly (though her temple still stood as high as a normal ponies would). Such appearances only added to the melting feeling in Celestia's heart when her gaze fell upon her young Sister.
Having gotten most of the celebrations dealt with, the tasks turned from fun to business as those under Celestia's rule worked tirelessly to accommodate the newly returned Luna to life as she would now know it. The past two days had certainly been a drain on Celestia; so much work to be done so quickly. She wondered why she had not worked in the days before her troubled Sister's return to make things right for her, such as preparing her proper quarters; but in retrospect, she knew exactly why. Confidence in her abilities to successfully break the hold on her Sister's heart and mind was something she did not hold. In all reality; she had been right about her own assessment, as Twilight Sparkle and her ensemble of friends had been the ones to harness the Elements of Harmony; not her. Such was the past, however.
Currently, the young Luna was with Canterlot's finest tailors as they worked to measure every inch of the Alicorn's figure; her Royal attire was something that could not simply be procured. Celestia had to give a chuckle at their diligence; she knew fully well that as the months went by Luna's figure would grow, her coat growing darker and her mane returning to the stellar wisps she knew her Sister to hold so many years ago, something that would quickly render their work null. But, at the same time; she couldn't let her Sister be bare of proper attire.
Turning from her place at the balcony edge the Sun's upholder stepped into the equipment-laden Observatory, the finer details of the room being unnoticeable, for a single tri-arm candle by the door was the only thing giving off light. Celestia's maw fell wide as she let out a yawn, her heavy hooves clopping loudly as she made her way towards the door; only a few more things needed her attention, then her retreat to slumber could be made. Celestia paused as a rush of unnaturally chilling air swept across her figure from the balconies way, her gaze peering over her shoulder to the archway.
A sudden breeze of this same cold air whipped through the circular room, its force taking the flame from the three candles, leaving the room nearly pitch black save for the dim castings of moonlight leaking through the balconies archway. Through the inky darkness, Celestia's gaze met with a pair of dimly glowing blue eyes, their sharp angle and slip pupils causing her heart to skip a beat.
"You..." Growled a deep, almost sinister female voice, a blue aura of magic sparking to life from above the pair of eyes.
Celestia's own magic swiftly awoke, her horn casting a deflection spell right as a fiercely powerful bolt of deep blue energy flew at her through the darkness, a strobe of light giving contrast to the room for a mere second as the deflected spell sparked into the floor, Celestia's eyes catching the silhouette a pure black mare, her combative blue armor shining along the contours of her figure and her swept wings unfurled to full length. Her hooves made a quick retreat, carrying Celestia backwards as her mind reeled, mouth agape as her thoughts echoed the same words: 'she's gone, she's gone'. The aura came to life through the darkness once more, Celestia readying the same spell as before, though no retaliations came from the horn. After a second step backwards, Celestia's haunches collided with an invisible force, her gaze not turning from her opponent as she knew well what she had run into.
"My, you seem very unpleased." The voice jested, the clop of hooves filling the room as she paced towards Celestia.
"You... aren't real. L-Luna only created you in her mind..."
A humming laugh rumbled from the evil-spawn's throat, her eyes still piercing into Celestia's, "Well, clearly; that isn't true."
Hoping to catch the sinister being off-guard, Celestia's deflection spell ceased as she instantly let loose a crackling bolt, the energy simply bouncing from Nightmare's armored peytral with a flash. Strafing sideways to distance herself from Nightmare, adrenaline began pumping through her veins as her mind reeled over her options. A blinding flash of energy caused Celestia to flinch, her own magic just being able to ricochet the assault. A stinging pain struck her right flank, Nightmare's magic skillfully bouncing a bolt from the curved ceiling behind and above Celestia to maneuver around her opponent's magical shield.
With a yelp, Celestia's figure rotated from the force of the impact, her horn's casting only ceasing for a moment, that moment being just enough for Nightmare's horn to magically connect with Celestia's, a crack bursting the room's air as she cut the Goddess of the Sun's magic from her abilities. Her legs collapsing from beneath her, Celestia fell sideways, her figure being caught by a cushioning force moments before colliding with the marble floor. Through blurry vision, Celestia's gaze locked with the seemingly floating pair of azure eyes, the aura above them cutting as Nightmare Moon let her incapacitated victim drop to the floor. Her ears ringing and head throbbing, Celestia's mouth fell open, her potential words being silenced as a spell from the being forcefully closed her mouth.
"Yes, yes, I know you're scared, and wondering how it's possible for me to be here," Nightmare grumbled, seeming annoyed, "That should be the least of your concerns, my dearest little Sun."
Celestia's eyes remained locked with Nightmare's as the fiend crouched down, "If you dare lay a hoof upon my Sister, I swear upon my own name that I-"
"I don't have any grievances with her; you of all ponies should know that."
Suddenly, a large, moist tongue licked its way across Celestia's muzzle, the sensation causing her head to recoil back from the jarring experience, "However, I do have a grievance with you..." Growled Nightmare, her brow furrowed.
The tongue pressed against her muzzle once more, Celestia's retreat being stopped as her neck was taken by Nightmare's aura. Seemingly as punishment, the tongue returned, this time gingerly passing across Celestia's unwilling lips, a short whimper escaping from her. After a moment's silence, Nightmare's horn came to life as it cast a faint blue glow, the light being enough to show her the confused and terrified Princess at her hooves.
"I know you well, and death is something you fear not. Tell me, Celestia," Nightmare's head craned down, her glowing eyes squinting, "What do you fear?"
A wince came to Celestia's expression as a strange pressure took over her temples, Nightmare's aura growing more intense as her eyelids fell closed. Gasping breaths escaped the Princess's lips as the pain within her head became horribly intense; her jaw falling open.
"G-Get out of my head!" She shouted, her body wiggling in Nightmare's magical restraints.
A Midnight blue aura took Celestia's muzzle once again, clamping it shut as the Princess let out a muffled scream. Nightmare's eyes re-opened, a small grin taking her expression as Celestia's pained eyes gazed into hers. Nightmare's spell finally ceased, Celestia's body fell limp, eyes darting around the nearly pitch black room as her chest heaved.
"I expected something far more complex from you, Celestia. However, I have no problem with what you've told me."
Mind reeling as to exactly what the fiend meant, a few mumbles came from her shut muzzle.
"What foalish question do you wish to ask?" Condescended Nightmare upon releasing her hold.
"W-What did I... 'tell' you?" Returned Celestia's quivering voice at an almost whisper.
A short gasp of surprise left her lips as a force took each of her legs, rotating her body to where she lay upon her back, her rear legs being left held in the air while her forelegs were pressed firmly at her chest.
"Let me explain..." Sneered Nightmare as she stood, her horn's glow giving just enough light to cause the mare's two razor-like fangs to gleam.
Watching as her assailant stepped to tower over her, a shudder of fear worked its way through Celestia's spine as the mare's hoof gingerly graced her soft stomach.
"Unfurl those wings of yours," Coaxed Nightmare in a venomous tone.
Celestia's terrified expression remained unchanged, her wings failing to leave her sides. The previously gentle hoof quickly moved to her crotch, pressing at her pelvis with great force, "Unfurl your wings," Snarled the black mare, her head craning to drill her gaze into Celestia's now misty eyes.
A shuddering sigh left the Sun Princess's nostrils as she turned her head from Nightmare Moon, eyes squeezing shut as she offered her compliance, the two white-feathered wings at her sides slowly extending to their full birth. Taking her hoof from between her victim's haunches, Nightmare corrected her position and crouched upon Celestia's figure, her magic spreading both her back and forelegs to allow her a comfortable position. Celestia's expression became more fearful as she felt a warm object between their bellies, her words stuttering for a moment.
"W-What's between us?" She stammered, seeing Nightmare's toothy grin return.
"You hadn't noticed as I paced around you?" Returned the black mare indirectly, standing from her captive Princess.
Celestia's head was allowed to crane upwards, her eyes falling upon the pure black, fully erect stallionhood hanging from between Nightmare's haunches. Her head fell back to the marble floor, a tear rolling down her cheek as her mind sped through ways to get herself out of the coming moments. A realization clicked in Celestia's mind; the horrible throb in her head had mostly subsided, and the sting at the base of her horn too was diminishing. Her powers were returning... slowly. If she was to have a way out of this, she'd have to stall.
"I have some humility, Celestia," As Nightmare once more brought her figure to rest upon the now struggling Princess, her aura took control of Celestia's left wing, bringing it from the floor to an upright position, "I wouldn't skip a little foreplay, as I'm sure you would."
Nightmare brought her face to Celestia's wing, the Princess wincing as the mare's fangs plucked a single long feather. A second feather painfully left her wing, Celestia's chest shuddering as tears slowly worked their way down her cheeks. It was clear Nightmare wished to enjoy herself with her new toy; Celestia began thinking how she could drag out this 'foreplay' of as long as possible before the inevitable happened. With another stab of pain as another of her feathers came loose, the Princess let out a groan of discomfort. Showing Nightmare more displeasure might make her want to toy around longer.
Bringing her head away from her victim's wing, Nightmare brought her face close to Celestia's, her sorrowful expression and fear-ridden eyes bringing a pleasured, yet sinister grin to the black mare's lips. Without a word, her saliva-coated tongue rolled from her fanged maw, sliding along Celestia's fuzzy cheek to lap up her salty tears.
"Get... get off of me," Celestia grumbled, her lower portion wiggling as she struggled at Nightmare's aura, her movement grinding the large member between their stomachs.
A short whinny of pleasure left Nightmare as she craned back down to Celestia's face, "Keep doing that..."
Celestia's dread-ridden eyes remained locked with her lustful, yet seemingly agitated capture, her lower body pausing in reluctance. As Nightmare's expression turned to a scowl, Celestia reminded herself of the plan. She didn't have much of a choice, and this, if anything, was far better than what the future held. A fresh tear made its way down her pure cheek as her lower body awkwardly and slowly slid side to side, the stallionhood at her belly giving a few throbs.
"You should be excited, dear Celestia. I'm sure it's been a fair time since you last had a mate..." Nightmare spoke, pressing her muzzle to Celestia's, "Am I not adequate for you?" She continued, her low voice holding a grumble.
Celestia's expression took a scowl as she turned to disconnect their muzzles, "What do you think?" She replied with venom.
A force surrounded her horn, holding her head in place as Nightmare's maw fell open, the two fangs hanging from the roof of her mouth stabbing into the meat of Celestia's neck. A loud yell left the Princess as the stinging pain caused her body to squirm, the motions of her haunches bringing a pleasured moan from Nightmare's throat, her bite clamping harder.
Now simply whining, Celestia continued to thrash at her magical restraints, the action making the horrid sting at her neck worsen as her neck moved around Nightmare's fangs. A short shiver moved through Celestia as the black mare's tongue pressed at her fangs, moving the flesh they dug into ever so slightly. Finally, Nightmare's teeth came free, her long tongue caressing the two fangs as she watched Celestia's eyes, hate burning through her pupils. Somewhat lovingly, the tongue came to the dripping punctures in Celestia's neck, the two streams of red being cleaned from her fur.
"You've stopped squirming..." Nightmare Moon stated, pressing her lower body into Celestia's, "I don't think I gave permission for you to stop." She growled, her brow furrowing as she pressed a hoof at the Princess's throat.
"W-Why this... why did you have to choose this...?" Celestia whimpered at a near whisper, offering no compliance as her lower body remained still.
The hoof at her throat pressed down, her inhalation turning sharp and rough. Nightmare brought her face close to Celestia's, anger at her toy's disobedience showing in her gaze.
"In retrospect, I fail to understand why I gave you any ounce of authority," Professed the black mare as she lifted her figure from Celestia.
Nightmare stood straight for several full seconds, a sniffle coming from her nose as a single drop of unknown liquid landed upon Celestia's chest, the Princess craning her head upwards to see a single droplet of blood had splashed to her fur. Her previous horror-filled expression changed to one of confusion as she watched Nightmare move her head to the side, her wing unfurling as it was used as a handkerchief.
"Are you bleeding...?" Cautiously approached Celestia, taking serious note of the weakness Nightmare may have just shown.
"Yes," She sniffled once more, bringing her hooves from their positions at Celestia's sides as she began pacing around her restrained toy.
Trying her best to not let a smile through, Celestia's thoughts came to life as she had an epiphany. Nightmare's abilities must be severely weakened from the events that transpired only a mere two days ago. It only made sense; if she were able to take a physical form outside of Luna's body, it would have taken a bit of power to do so. Celestia could only guess, but she found it safe to assume that Nightmare's powers had been fairly weak during their initial engagement; she had just put all of her might into it. All of that, combined with her constant need to restrain Celestia's movements, was probably giving her quite the headache.
Her own horn could most likely do little more than open a heavy door without causing her to pass out, but seeing Nightmare Moon's own weakness made the glimmer of hope she could avoid what hung between that spawn of Tartarus's legs shine a little brighter. Celestia's head rolled back, her eyes meeting with Nightmare's as the towering mare had stopped her pacing and now stood above her, the silhouette of her half-erect rod drawing her sight. Minutes; that's all she would need.
"You're weak, aren't you?" Probed Celestia.
Her words seemed to take a moment to register with the black mare, "Not as weak as you,"
Minutes might be excessive. Suddenly, Celestia's body was moved to where she no longer lay flat, but at an angle, the spell-cast restraints at her forelegs forcefully bringing her limbs to a straight position, pulling each limb around her half-furled wings to where they were pressed to her back instead of her chest. Nightmare's hoof was brought from the floor as it gently traced along Celestia's long horn, a yellow spark of energy leaving the horn's tip as her blue metallic shoe disconnected.
The simple act brought their gazes together, Celestia's eyes widening as Nightmare's narrowed, realization striking them both. In perfect anticipation, Nightmare's hoof forcefully struck the side of Celestia's head as a bolt of magic leapt from Celestia's horn, a crackle breaking the air of the room as the bolt collided with the ceiling instead of its intended target. Celestia let out a yell of agony as Nightmare re-cast the spell to disable her horn, the spell being held for quite some time as the air crackled with magic.
"I... I thought I got rid of that!" Barked Nightmare, her head throbbing fiercely and figure beginning to wobble as her horn's glow began diminishing, the restraints at Celestia's limbs becoming weaker.
Noting the lightening grip, Celestia's rear legs gave a strong kick, the aura surrounding her hooves simply vanishing. A pained grunt escaped Nightmare as her horn's light came back to its full brightness, her aura re-securing Celestia's freed legs.
"No! No... I got this far... you aren't getting away that easily!" Nightmare exclaimed, her rage-filled eyes dug into Celestia's.
A now steady drip of blood left Nightmare's nostrils as she spread her legs, steadying her figure.
"You are very lucky... if I had stalled you for just another minute, there'd be a lot more blood than that coming from your nose." Snarled Celestia, pained cries shuddering her chest as her hate filled eyes glared at Nightmare, who's expression held a wince of pain.
Nightmare let out a growling exclamation of both anger and pain as her hoof struck Celestia's temple, a short yelp coming from the Princess at the sudden blow.
"Enough! You... You've had enough talking." Fumed Nightmare as she took a step forward, her figure coming over Celestia's as she placed her armored hooves at each of her victim's haunches.
A gentle tickle came from the tip of Nightmare's half-hard stallionhood as it gently brushed Celestia's lips, the member giving it a pulse from the sensation. An aura took the upper portion of Celestia's neck to hold her head still as Nightmare gave a thrust, the somewhat limp tip of her member simply bumping at her toy's firmly shut lips.
"Lick it." Nightmare stated blandly, her words bringing zero response from Celestia.
A moment went by without any movement from the Princess. An agitated scowl took Nightmare's expression as she craned her head down, her magic bringing Celestia's left leg to her open mouth as she firmly clamped her two huge fangs, along with the other razor-like teeth in her maw, into the flesh just above her hoof. A pained yelp left Celestia as Nightmare's gnaw increased in strength, a fresh copper-taste taking over the taste already in her mouth from the blood that leaked from her nostrils.
"O-Okay! Stop! I... I'll lick it... j-just stop biting me!" Celestia pleaded, her words shuddering as tears worked their way down her cheeks.
The teeth exited her flesh, the two large punctures and two lines of smaller marks beginning to leak red, "Good." Spat Nightmare, enmity dripping from her words.
With much reluctance, Celestia's tongue left her lips and slid along a portion of the stallionhood, no indication of pleasure coming from the mare above her. Another lick brought forth a pulse, Nightmare shifting her body back a tiny bit to where the tip of her rod lay at Celestia's lips.
"I'll be kind and warn you... you need to be more active." Nightmare explained with venom, her words bringing an almost instant compliance from Celestia as her mouth opened to accept the tip.
Her tongue gently pressed at the member held by her lips, a quiet groan leaving Nightmare as her stallionhood gradually became more erect. A whimper came from the Princess as her assailant stepped forward, the now fully hardened mass pushing into her unwilling mouth. The aura which once held her neck moved upwards, taking her jaw and forcedly opening it to the maximum as Nightmare gave a hard thrust, her warm, thick rod pushing into Celestia's throat. Muffled chokes escaped the Princess as the black mare steadily began thrusting in and out, Celestia's quick breaths shaky as a mix of terror and agony took her emotions. Groans of ecstasy left Nightmare upon giving a single hard movement, the Princess gagging loudly as the rod pushed fully into her throat.
"You're good at this..." Mumbled Nightmare as she simply held her position, the vibrations of her toy's choking tickling her girth.
Celestia's eyes squeezed closed, pained tears streaming from her eyes as the thrusting continued, the rod deep in her throat causing breathing to be a chore. A muffled yell of agony came from the Princess as fangs were brought to bear on her other rear limb, the bite digging into the meat above her knee joint. Through her fangs came a grumble of pleasure as the vibrations and tongue movements caused by Celestia's cries sent waved of ecstasy through her body. A little twist of her head brought another yell, Nightmare's eyes closing as she gave a hard thrust, her tip pushing at the back of Celestia's moist tunnel.
Feeling a strong burning of pleasure, the black mare took a step back as her rod's long length was brought from Celestia' throat, her tip remaining within the Princess's mouth. The fangs dug into her toy's leg came loose as Nightmare groaned loudly, her stallionhood throbbing as she reached a somewhat quick climax. Four strong pulses filled the unwilling mouth of the Princess to it's maximum, Nightmare shuddering from the feeling as she stepped back, her magic forcefully holding Celestia's cum-filled mouth shut upon the exit of her stallionhood's tip.
"Swallow." She stated simply, Celestia once more not offering her compliance.
After a moment of glaring at the Princess, Nightmare brought her face close to Celestia's, "Swallow..." She enunciated slowly, Celestia's blood-shot eyes locking on the two fangs within Nightmare's maw as she spoke.
The Princess closed her eyes, her throat not giving its compliance as she continued to hold the load in her cheeks.
"You swallow or I bite." Nightmare grumbed through gritted teeth.
A quiet, shuddering whimper came through Celestia's sealed lips as a few fresh tears made their way down her cheeks. With much reluctance, a single gulp brought the still warm cum down her throat, her compliance bringing a closed-mouth laugh from Nightmare.
"I don't understand what you gain through your disobedience."
After speaking, the aura holding Celestia's lips was released, the Princess instantly turning her head as she spit repeatedly to try and clear the aftertaste of Nightmare's liquids from her mouth. Nightmare, upon giving off a loud sniffle to pull what blood leaked from her nose back in, sat down on her haunches above Celestia, the spell-cast restraints at her victim's limbs coming undone except for a single band of magic tightly grasping her throat. Her magic needed a rest; constantly suppressing Celestia's struggles combined with the energy it took to maintain her stallionhood's functionality was beginning to take a serious toll on her over-worked horn. Nightmare's sight wandered to Celestia's, seeing that the Princess's teary eyes were locked with the dripping rod lying lazily along the marble floor between her haunches.
"You've been awfully quiet, little Sun. I miss that sweet voice of yours." Taunted Nightmare in a falsely loving tone.
Celestia offered no words, simply closing her eyes as she tried to use Nightmare's break as time to prepare herself mentally for what was sure to be next. A choking grunt left Celestia's lips as the aura at her throat suddenly tightened, her eyes going wide as Nightmare lifted her from the marble and spun her so they were face to face. After being forced to her haunches, Celestia's eyes darted from Nightmare's aggressive expression to the phallus between her legs, a midnight blue aura of magic steadily stroking back and forth along its length.
A horrible grin took the normal scowl upon the deviant's face as she continued pleasuring herself, Celestia's throat emitting a dry choke as the spell gripped tighter and tighter. Her tear-blurred vision began to lose some of its fidelity as her neck crushed beneath the aura, fresh tears rolling from her cheeks as air failed to make it through her windpipe. The ring of magic pleasuring Nightmare moved down her shaft past her medial ring, its speed increasing as the sensation of her victim's throat in her magic provided an oddly satisfying pleasure.
Celestia's hooves slid against the smooth marble as she made a futile attempt to escape, her thoughts being consumed by terror. A mumble of pleasure came from Nightmare, her sinister gaze remaining locked with Celestia's still wide eyes as she pulled the Princess close, their chests colliding. Celestia weakly brought up her hoof, hitting Nightmare at her temple through her helmet, the action giving zero response from Nightmare as her horn continued stroking her throbbing length.
Their gazes remained locked, Celestia's eyelids beginning to droop as no sound came from her horribly constricted throat, her sight now being nothing more than heavily blurred colors as her limbs lost their strength to be held up. Nightmare's spell-cast grip forcefully brought the nearly asphyxiated Celestia onto her side, the spell squeezing her neck pulling her head to the marble as Nightmare moved forward, her haunches lifting a short distance from the floor, bringing the bobbing tip of her self-pleasured stallionhood a short distance from her so far unresponsive toy's face.
The flesh and fur of the Princess's neck moved inward further as Nightmare's grip tightened even more, her expression holding a pleasured grin as her rod tingled in hot ecstasy. A sporadic kick came from one of Celestia's bloodied back legs, Nightmare watching the limb's strong movement slow to a steady tremble. Her grip loosened somewhat, the only response from the action being a twitch from the Princess's lazily open jaw.
Nightmare's head lowered as a low groan left her throat, burning pleasure flowing through her body as she began to climax, her raised haunches lightly thrusting as a hard throb sent a steady squirt of warm cum onto Celestia's face. Nightmare's aura continued moving in long strokes, pump after pump splashing her toy's face, a puddle forming on the marble from the excess. The magical clamp at Celestia's throat pulled her close, her completely limp body sliding a tiny bit from the movement as Nightmare quickly pushed her tip into Celestia's slackjawed mouth, two final squirts completely filling her cheeks.
The glow from Nightmare's horn stopped entirely, her haunches hitting the floor with a thump as she let out a long, sighing moan. Having had all pressure taking from her throat, Celestia's chest finally began to move, her legs moving in an uncoordinated manner as her blood-starved mind regained function. Nightmare's hooves pushed to the marble as she moved back, the tip of her exhausted stallionhood lazily sliding free of Celestia's dripping mouth, gasps of air now making their way past the liquid. The midnight blue aura came back to life, forcing Celestia's lips shut as Nightmare craned her head down, looking into the Princess's now open and scared eyes.
"Swallow." She spoke with a fang-ridden grin, Celestia's hooves shaking as she quickly complied.
Upon being released, Celestia's mouth fell open as she resumed gasping, tears flowing down her cheeks as her entire body shivered in both pain and terror. She couldn't pull air in fast enough, her vision still somewhat fuzzy as her sight darted around the dark room. Her ears seemed to rumble from the pounding ache in her temples, the place where Nightmare's magic had crushed her neck beginning to burn with pain as sense returned. Her chest shuddered, eyes closing as the combined pain and fear broke her ability to not fully sob before her capture, raspy whimpers leaving her lips.
The horrible feeling of Nightmare's tongue dragging across her cum-soaked cheek caused Celestia to yelp, her eyes coming open and front hooves sliding against the marble as she moved from beneath the black mare crouched over her. Nightmare's magic took Celestia's horn, pulling her face back close to hers as she glared at the Princess. Celestia winced as the warm tongue returned, Nightmare lapping her own fluids from the white fur of her toy's face, somewhat enjoying the taste. Having cleaned Celestia's right cheek, Nightmare moved to her muzzle, licking all the way from her chin to her horn.
"G-Get away from me!" Snapped Celestia, her front hooves managing to land a square hit at Nightmare's chest just below her armored peytral.
The resistance from her toy only strengthened the spell holding Celestia's horn, an aura taking each of her four hooves and holding them in place as she went on cleaning, most of Celestia's face now wet with saliva. One last drag of the tongue took Nightmare's cum completely from the Princess's fur, her wet lips planting a quick kiss upon Celestia's.
"Please... Please get off of me! I... I'm sorry!"
The cry from Celestia froze Nightmare, her eyes locking with the Princess's, "Do you really think 'sorry' repairs anything?"
"I know it doesn't... b-but what do you want from me? Luna has returned, the ponies of Equestria no longer shun the night away... and you... you have a physical body!" Celestia sniffled, "What do you want from me?"
Celestia's rear hooves were lifted by Nightmare's aura, bringing her rear end high from the marble, "I want revenge."
Celestia's hanging hind quarters were brought back, her body sliding along the floor as Nightmare placed chin at Celestia's crotch, her glowing eyes biting into the Princess's. A humming chuckle came from Nightmare as she brought her head down, licking at Celestia's unwilling marehood. A shiver went through her body as Nightmare continued to tongue her, the unwanted pleasure causing her to give restrained moans. Nightmare's mouth opened completely, her tongue forcing through Celestia's lips as she cupped the marehood in her mouth, her two fangs gently poking Celestia's crotch.
The tongue paused its dance as Nightmare brought her gaze to Celestia's, the fear-stricken Princess shivering as Nightmare brought her mouth from her saliva-coated marehood. She stood from her haunches, the aura holding Celestia's rear legs spreading the two limbs as Nightmare stepped over Celestia's figure, her dripping erection pressing to her crotch. Upon placing her front hooves firmly at Celestia's sides, an aura surrounded the hungering stallionhood between her legs, the large tip pressing through her victim's tight, puffy lips with a thrust. Celestia simply shut her eyes as the rod drove fully into her marehood, its length seeming to go on forever. She let out a surprised gasp, Nightmare beginning to thrust deep and hard, her large stallionhood stretching the deepest walls of Celestia's tunnel. Unwanted pleasure brought small moans and grunts from the Princess, tears once more beginning to work their way down her cheeks.
"Having fun?" Nightmare grunted through her moans.
"N-No..."
Much to Celestia's surprise, Nightmare slowed her hard thrusts, pausing all movements as her eyes were drawn to Celestia's, "Neither am I. You aren't screaming..."
Grinning as Celestia's eyes widened, Nightmare pulled her hard member from the tight walls of her toy's marehood, a spell taking her tip as she aligned with the ungiving and tight hole below Celestia's tail, a panicked expression coming to her face as she realized what was about to happen. No words came from the Princess as the tip of Nightmare's stallionhood forced its way into her extremely tight anus, a shuddering moan coming from the pure black mare as she slowly pushed her way inside.
"O-Oh... that is amazing... why didn't I start off like this?"
Gasps and groans of pain came from Celestia as the rod continued pushing, the painful sensation in her gut paralyzing her usual struggles. Fully hilted, Nightmare hastefully drew hew haunches back, a yell leaving Celestia as the member left her tight anus half-way before thrusting back in. A somewhat quick rhythm was picked up, each hard thrust causing her to yelp, chest heaving as she cried. The pained expression on her victim's face gave Nightmare a grin, her thrusts now at a steady pound, pleasure tingling her entire being from the incredible feeling of Celestia's tight, gripping walls. She was getting close to a third orgasm; her mind thinking to slow down to prolong the experience, but her body chose to only continue at the current pace.
Soft grunts now came from Celestia as she did her best to suppress her whimpering sobs, her gut aching and anus stinging as Nightmare's hard thrusts continued. The restraints holding Celestia's front hooves pulled upward, bringing her body completely off the floor as her chest met with Nightmare's, her front legs coming from the floor and wrapping around her toy as she continued thrusting, her head lowering to Celestia's; tongue sliding from her lips to taste at the teary stream running down her toy's cheek. A yelp of pain came from Celestia as Nightmare's maw opened wide, clamping her fangs to where her victim's head and neck met. A single, hard thrust drove Nightmare's entire member deep inside, the act bringing a second yell from Celestia.
Shudders drove through Nightmare's, her rod throbbing hard as her thick juice filled Celestias's walls. A loud moan flowed from the clamped maw of Nightmare, her orgasm completely pausing her movements as her member pumped several times more. Her fangs pulled from their wounds, Celestia gasping through her hard sobs as Nightmare's hooves went back to the ground, stepping back to pull her spent Stallionhood from the tight hole. Upon flopping free, a healthy stream of cum ran from the slightly agape hole, Nightmare's horn completely ceasing, dropping her toy to the marble with a loud thud, Celestia's fear-paralized figure remaining still as her chest heaved with heavy sobs.
"I...I-I hate you..." Celestia whined, her head shaking side to side.
"I don't hate you. You see; hate it a fairly strong term. Normally; when you hate something, you want it gone," Returned Nightmare, panting lightly, "I don't want you gone. You're simply too much fun."
As she began towards the door, a quick flash came from between Nightmare's legs, the flopping, black member vanishing as her marehood returned.
"Goodnight, my dearest little Sun. I should like to see anypony around the castle believe you when you try explaining what happened this night," The swept, pure black wings at Nightmare's sides unfurled, her head craning to Celestia's to meet her gaze with the blood-shot eyes of her victim, "It won't be long til we see one another again."
Through her own cries, Celestia could hear the clop of Nightmare Moon's hooves grow distant, the flap of large wings filling the air as the black mare took off from the open balcony.
