The Squared Circle (Pt.1)

The arena that night was packed with ponies of all shapes and sizes, and from all walks of life. Squashed together in tiny seats, nobles sat unperturbed next to commoners, cheering in unison as brothers and sisters brought together by a single, common goal: To watch two incredibly hot mares beat the stuffing out of each other.

A noble cause, indeed.

Celestia felt queasy; it was an odd feeling to move without actually moving. Similar to teleportation, the feeling of being displaced in the blink of an eye was never a pleasant one. How the hay did Nightmare reshape the dreamscape so quickly? It wasn't something even Luna could pull off easily, and Celestia wondered just how much power Nightmare had gained since their last encounter.

Celestia found herself seated on a stool and wearing a pink satin robe that hugged her body comfortably, while across the ring, her opponent sat draped in Persian-blue. Nightmare rested her head idly on the padded turnbuckle as she watched Celestia with a predatory glare.

They were too far to actually speak to one another, but the sun princess felt a chill down her spine nonetheless. Trying to ignore her gaze, Celestia observed more of her surroundings instead. It took her several seconds to actually begin taking in the changes around her. Everything was certainly...vivid. It was distinctly real compared to her own dreams, or the masterfully crafted ones she was occasionally given by Luna as a gift.

Celestia blinked.

The world around her was just so bright, and loud. Massive spotlights hung above on the ceiling, illuminating the ring and much of the arena. Everything was surreal; from the warmth of the light on Celestia's fur, to the deafening screams and cheers of thousands of ponies, and the odd weight on her hands.

She looked down to find both hands covered by neatly laced-up boxing gloves.

Huh.

"This is her idea of a fight?" Celestia frowned. She had imagined a magical duel, or something of the like, or perhaps even a reenactment of their encounter a thousand years ago. A boxing match was certainly a far cry from anything she could come up with.

Did Nightmare Moon even know how to box?

Celestia didn't love the sport, per se, but she'd watched hundreds of them in her lifetime. Championship bouts usually benefited from her presence in the VIP box alone, especially when charity was involved.

Yet, unarmed combat was not quite Celestia's forte.

When she did have to fight, she'd use magic and blast her foes to giblets or banish them to the moon, depending on her mood. She knew how to handle a sword, too, but bashing her opponents bloody with her fists..? That was more of Luna's thing.

Celestia looked across the ring at Nightmare, who apparently had not once looked away. In fact, she was now menacingly tapping her gloves together in a slow and deliberate motion.

Celestia gulped.

"Ladies and Gentlecolts!" A powerful voice boomed across the arena. The sound resonated up the rafters of the arena, practically shaking the support beams that held the spotlights in place.

"Tonight, I brrrrring you the match to end all matches!!!"

Celestia's body stiffened at the sound of the announcer's opening address. Her mouth was dry, and her heart and mind was racing. The announcer spoke with the clarity and the sheer power of the Royal Canterlot voice, and every dramatically punctuated word shook her to the core. She looked up to see a surprisingly short, pudgy earth pony in a suit two sizes too small, hopping about the ring to rile up the crowd. Needless to say, she was a tad bit disappointed.

Celestia zoned out as the announcer went on a noisy tirade, bringing the crowd to the point of barely contained excitement. She had better things to do than watch the tubby fellow bounce around the ring, anyway.

Like subconsciously trying to bite her nails repeatedly and accidentally punching herself several times in the process.

"In the blue corner, featuring the sexiest mare in all of Equestria; our very own goddess of the night, the harbinger of terrors, the beautiful, the undefeated, Nightmare Moon!"

Nightmare's dream 'fans' yelled in support, and Celestia rolled her eyes in annoyance as she watched several mares in the crowd swoon dramatically. Many of the ponies in the audience were wearing dark blue and purple, while holding signs that bore a crude image of the magnificent crest on Nightmare's ass.

Great, Nightmare had conjured up her own fanclub.

"And herrrrr opponent!"

Celestia's ears flicked, and she perked up.

"With flanks as large as the Sun itself and a waist size spanning the Equator, Princess Celesia!"

There was a round of chuckles.

WHAT.

Now, Celestia knew for certain that she was most definitely NOT fat. She was trim, and any blubbery goodness tended to go into places where they were actually needed, like her curves. Her gorgeous body was something she took great pride in, and nothing could make her think otherwise.

But still.

"Hey!" She yelled angrily. "My flanks are perfect!"

The announcer seemed to not catch that, and continued on.

"Also voted most likely to be knocked out in the first round and be left with a concussion! Ladies and Gentlecolts, will Solestia stand a chance?"

The crowd responded with a resounding 'NO!'

Ooooh, Nightmare, you fucking bitch.

"It's Celestia, damn you!"

"Exactly what I said!"

The announcer finally hopped out the ring, leaving a seething Celestia behind. Maybe she'd knock him out too after she mangled Nightmare. Definitely.

“Alright, Tia…You can do this. Beat her up and you get to go home.” Celestia whispered to herself, eying the pinkish-white boxing gloves she was now wearing. The insignia of the Sun was proudly displayed on both of them, and for a brief moment, she relished at the thought of clocking Nightmare in the nose with them.

She looked up to see Nightmare in her corner, attended by two attractive thestrals as they prepped her for the match. Celestia's eyes widened as one of them began kissing the underside of Nightmare's muzzle, alternating between pecks and small licks as she trailed downwards along her mistress' slender neck.

Celestia narrowed her eyes at the sight. Why couldn't she have one of those?

"Hi Princess!!!"

Bweh.

Celestia was startled from an increasingly heated train of thought by a perky purple pony princess.

"...Twilight?"

Celestia gawked at her student with a befuddled stare. "Is it really you?"

Twilight responded with a sheepish smile and a cute giggle. "I think so? I'm having the weirdest dream right now."

A bit of Twilight's mane promptly sprang from its orderly position, away from the rest of its sisters. It was a relief to have a familiar face to support her, but if Nightmare had trapped Twilight in the dreamscape as well, then the implications were clear.

Celestia fumed on the inside. Nopony touches her student. NOPONY.

"So...boxing, huh." Twilight mentioned casually as she leaned on the turnbuckle, snapping Celestia out of her reverie.

"So it would seem." Celestia looked across the ring silently. "Twilight, would you like to help?"

"Me? But I don't know anything about fighting."

Celestia smirked. "I just need someone to take care of me in between rounds. Do you think you could handle that?"

"I..." Twilight paused, before nodding eagerly. "I''ll be the best assistant you could ask for!"

"My second, Twilight. You're going to be my second."

"Yup!" Twilight giggled, albeit with a touch of creeping insanity that tended to affect her from time to time.

Oh, she is such an adorable munchkin.

Celestia smiled warmly at the beaming princess. "I'm glad you're here."

"So..." Twilight picked up a blue mouthguard and waved it in front of Celestia. "Let's get you ready."

Celestia shut her eyes and parted her lips, but she opened them the moment she felt two soft hands press gently on the side of her cheeks.

"But before that, since this is a completely nonsensical dream and all...Princess, I've always kind of wanted to..."

Twilight pressed her lips against Celestia's own in a feather-soft kiss, much to her surprise. It was a sweet, gentle gesture...

...at first.

Twilight promptly shoved her tongue into Celestia's mouth and began vigorously frenching her.

"Unf!"

Unbidden, Celestia found herself enjoying the insanity. She reached down and cupped her faithful's student's perfect ass-cheeks and squeezed, prompting an adorable squeak from Twilight.

The student had already mapped out half of the insides of Celestia’s mouth, diligently committing it to memory, when Celestia broke the kiss, much to her disappointment.

"Twilight?"

"Hmm?" Twilight panted in response, ready to dive back in.

"I think the MC is waiting for us."

Twilight turned to see the stallion tapping his foot impatiently. He shot an annoyed glare at her, much to her embarrassment.

"Can we continue?" He asked in a frustrated tone, dragging out each word slowly.

"Y-yes..of course! Please do!" Twilight squeaked.

"Good," He turned his nose up snootily. "Ladies! You may disrobe."

"About time." Nightmare grunted.

Celestia rolled her eyes. She grasped the strap on her robe with her gloved fist, and pulled gently. She felt the silk robe loosen around her, and in a familiar motion, she shrugged her shoulders to let the soft silk slide right off her body.

The arena exploded into a cacophony of applause and catcalls.

It was two seconds later that Celestia realized that there was a distinct lack of other garments on her body.

"Eeeeeeek!!!!" Celestia yelped, and her initial reaction was to fold her arms across her full breasts and squeeze her thighs together in an attempt to preserve her dignity.

The crowd laughed once more, as did Nightmare, who casually removed her own robe and tossed it aside, displaying her most glorious assets to her adoring fans.

Celestia whipped her head around, only to see her ever-faithful student throw the crumpled cloth away.

"Oh, ponyfeathers," she muttered, woefully staring at the discarded robe outside the ring.

"Is everything alright, Princess?"

"Nightmare Moon is insane," she mumbled grumpily.

"Err...I think we established that back when she tried to bring about eternal night."

Celestia blinked, but eventually settled for a dull sigh. "Let's...just get this over with."

"Alright then!" Twilight chirped. "You wouldn't want to disappoint all those ponies!"

She gave the solar princess a light shove, pushing her away from the corner. "Good luck!"

Celestia yelped in surprise, but her voice was drowned out by the sound of the bell clanging.

DING DING DING!

"Was this how you fought her a thousand years ago?!" Twilight yelled.

Celestia turned her head. "NO! Goodness, Twilight, what makes you think-"

WHAM

Twilight's jaw dropped.

She never saw Nightmare coming.

Celestia saw stars right after the first punch. A powerful cross rocked her head sideways, whipping her colorful mane wildly and forcing her to take a step back to balance herself. She turned her head back just in time to see Nightmare's glove fly straight into her forehead, just below her horn. She raised her gloves to protect herself, but she was a millisecond too late.

WHAM

Nightmare's fist slid just above Celestia's own as she struggled to raise them, allowing Nightmare to deliver the full force of the blow to her nemesis. Celestia's head snapped back violently again, this time with a loud grunt of pain as the nerves at the base of her horn registered the trauma.

Celestia moved her left foot back to brace herself as she launched a counter-punch at her opponent, but her glove only met with air as the other mare shifted to the side to dodge the blow.

"Too slow." Nightmare taunted before punching Celestia in the gut.

Celestia's eyes bugged out as she felt the air rush from her lungs, causing her to wheeze slightly. Not one to give up so easily, the sun princess jabbed at her opponent, only to meet with Nightmare's purple glove. Casually deflecting the blow aside, Nightmare slammed her other fist right into Celestia's face, sending the other mare tumbling backwards.

Celestia didn't realize how much she had retreated until her back slammed against the turnbuckles. Nightmare grinned, seeing her prey right where she wanted her. Backed into the corner, Celestia was still reeling from the punch. She was breathing heavily, her trembling hands were raised weakly in an attempt to protect her face, and her legs were shaking.

Nightmare gave her little respite and began to furiously rain blows down on her, repeatedly pounding Celestia's unprotected stomach. Every hit was punctuated with a high-pitched cry of pain from the sun princess, reverberating across the arena like music to the Nightmare Moon and the cheering crowd.

Celestia's brain was flooded with the amount of pain she was receiving as it struggled to make sense of everything. Primarily, it was trying to decide how to trigger her natural response to the situation as the adrenaline coursed through her body.

Fight or flight.

Fight.

Fight, damn you!

With as much force as she could muster, she shoved Nightmare back and jumped out of her corner swinging. The crowd cheered as she began to fight back, much to Nightmare's ire. Two quick jabs managed to strike the dark mare on her left cheek, but Nightmare responded with a powerful uppercut that smashed into Celestia's chin. Her head was rocked upwards as the blow dislodged Celestia's mouthguard, sending a spray of saliva visibly flying upwards like a fine mist.

Celestia took another step back, but learning from her previous error, immediately followed up with a side-step to her right. Nightmare's glove sailed right by her, inches away from her muzzle.

Now.

She shifted her body weight to her right foot. Her back and core muscles tensed, and she twisted to launch a powerful hook. Her fist flew in a graceful, horizontal arc and her glove smashed sideways into Nightmare's chin.

For the first time in the match, Nightmare yelped in pain. The blow rattled her jaw, and a numbing pain began to form around the area. She backed off quickly, staying out of Celestia's reach as she raised her glove to shift her maw slightly to check if anything was broken. It seemed alright, but stars above, it hurt.

Celestia readjusted her mouthguard, then raised her fists and began to approach Nightmare in an attempt to press her advantage, but she moved too fast and too recklessly. Nightmare calmly arced her back and reared her head back slightly to dodge the incoming shot, and the golden sun on Celestia's glove stopped mere inches away from Nightmare's face. Celestia's reach was too short and her distance was too far, leaving her open to a counter from her opponent.

Time seemed to move slowly, as if to taunt Celestia's fatal mistake. Her eyes widened, her jaw loosened and her mouth opened ever so slightly as if to say; 'Oh,' as she watched Nightmare's fist approach her in a counter-punch.

Nightmare slammed her fist into Celestia's right eye, eliciting a loud scream from her as her vision went blurry. The sun princess backed off blindly, only to find herself unwillingly pushed back by the elastic of the ring ropes. She bounced back, right back into Nightmare.

With a grin, the dark goddess cocked her fist back and launched a straight punch aimed for Celestia's face, but much to her surprise, her opponent ducked and struck her with a blow to her ribs.

"Urf!"

Nightmare grunted, turning quickly to face her opponent, only to find an empty space where she expected Celestia to be. Another blow came from her left, striking her in her side once more. She winced, but absorbed the blow and recovered quickly. She caught a glimpse of Celesita's rainbow mane, right before another blow sailed towards her cheek. She sidestepped the shot, and prepared to counter.

Celestia grunted in annoyance when she failed to smash Nightmare's pretty face in, but a second later she was yelping loudly as Nightmare unexpectedly latched onto her outstretched arm.

She hooked her own arm around Celestia's until her own glove touched the back of her shoulder, effectively locking her in place. Celestia cried out in surprise and tried to dislodge herself, but Nightmare's grip was firm.

Celestia was busy panicking and trying to dislodge herself when Nightmare's haymaker smashed into her face. Her body rocked backwards, only to be held in place by the impromptu arm-lock. Her shoulder and arm joints were bent painfully from the awkward angle, made even worse when Nightmare forced her forwards so she could strike her again.

Celestia winced, but she forced her body to fight back. With her free arm, she swung repeatedly at Nightmare and succeeded in hitting her several times to repay the punches that were coming her way.

It was a mutual handicap, with Nightmare's left hand unusable as it held Celestia's right locked in place, but it failed to stop both mares from delivering fast and furious blows in any way they could. The shouts and screams of the audience were punctuated by Celesita and Nightmare's own as they pummeled one another with reckless abandon. Every dull thud and wet smack was met with a loud cry of rage and pain as each mare attempted to out-punch the other.

Nightmare was able to sneak more blows in, and eventually, she was beginning to tire out her opponent. Another powerful jab managed to send Celestia reeling, and at last, Nightmare released her hold.

Taking two steps back, she prepared to launch a killer straight to knock her opponent right off her feet, but she hadn't expected Celestia to dash forwards in desperation to catch her in a clinch. Throwing her arms around her sides, Celestia caught hold of the other mare weakly to prevent her from punching back.

The feeling was electric as their sweat-matted fur came into contact, brushing firmly against each other. One fighter could hear the labored breathing of the other, and feel the furious thumping of excited hearts as it beat in tandem.

"Aww...is my little sun cunt tired?" Nightmare recovered quickly and began to tease, squeezing her arms a little tighter to hug her opponent closer.

The feeling of Celestia's breasts against her own was certainly an interesting one, and she began to slowly shift from side to side causing their teats to harden as they rubbed against each other. Celestia bit back a moan, shutting her eyes as she tried to ignore her growing arousal.

"You know, you'd make a half-decent sex slave."

"S..Shut up." Celestia pushed back angrily. "I can fucking do this all night long, bitch."

"I was hoping you'd say that." Nightmare let loose a sinister laugh, sending shivers down Celestia's spine. "Let go, so I can break you."

Celestia managed to catch her breath and shake the dizziness away during that short time, and with another small surge of determination, prepared to continue the fight. Nightmare felt Celestia's arms loosen around her, and with a grin, she loosened her own grip in turn.

Celestia steeled herself, and took one deep breath to prepare-

DING!

The bell clanged, signaling the end of the first round.

"Tch." Nightmare grunted in frustration.

Both mares shoved each other roughly, putting some distance between them.

"Fighters, return to your corners!"

Celestia didn't move, at first, as if exposing her back to her opponent would invite a beatdown. Nightmare snarled at her and turned around to return to the corner.

Perhaps that was a wise decision.

Celestia herself trudged back to her corner with her face and stomach covered in light bruises. Her cheek was beginning to swell slightly, and her entire body ached from the intense burst of physical exertion.

She wished she had laid off all the cake, but it was far too late to think of that.

Celestia jumped ever so slightly when she felt a freezing sensation numb her cheek.

"Sorry..." Twilight said in a quiet voice as she pressed the ice pack firmly against the swelling.

Celestia shot a glance at the smaller princess. "Twilight, are you alright?"

"How can I be?! You...You're hurt!"

"It's boxing, Twilight. Somepony is bound to get hurt."

Twilight's demeanor had largely changed, from gleeful to downtrodden.

"I don't like seeing you get hurt." She muttered, as she moved the icepack to Celestia's other cheek.

There was a brief pause as Celestia sat in relative silence while Twilight tended to her.

"Twilight...do you know why you're here?" Celestia asked in a soft, comforting tone she would use back when Twilight was a filly.

"No. I just want to wake up now." Twilight's voice cracked, and her shoulders slumped miserably.

"But you can't."

Twilight reached up to pinch herself on the cheek. "I can try."

"Twilight." Celestia sighed in frustration. "We're under a hex."

"...What?" Twilight's eyes widened. "You...mean...it's really, really you?"

Celestia nodded grimly.

"Nightmare trapped me in a dream."

Twilight's mental fortitude began to crumble ever so slightly.

"Then that means..."

"She's trapped you here too."

Oh.

So the dream was a construct of Nightmare Moon, and didn't quite belong to her. In a sense, that explained why everything was so violent. It also explained why it hadn't quite devolved into a hot and messy threesome in the ring yet.

There was a brief moment of silence before Twilight piped up nervously.

"About that kiss..."

"We'll have time to discuss that over tea sometime, Twilight."

There was a another awkward silence as she reached up to wipe a bit of sweat from Celestia's forehead.

"So...what happens if you...umm...lose?"

"We'll be asleep for an eternity or so while Equestria is plunged into eternal night."

Twilight grimaced.

Mother Faust, this was serious.

"Round Two, ladies and gentlecolts!"

“Good luck, Princess!”

The bell clanged again, and this time, both mares left their corners to meet in the middle of the ring, ready to exchange another flurry of blows. As Celestia stepped closer to the center of the ring, the odd, bubbling sensation in her chest only intensified. It began to well up the moment she opened her eyes in the arena, and she was getting more and more excited as she neared her opponent.

It was a feeling something she had not felt in hundreds of years.

Fire coursed through her entire body, giving her a heightened sense of clarity that could never be felt in a stuffy meeting room or her royal court. Her heart was thumping hard in her chest, beating in-sync with her footsteps and the chanting of the crowd.

She wanted more.

She needed more.

And Nightmare Moon was just the pony to give her what she needed.

Gone was Celestia’s fear, replaced with powerful confidence. A sudden dash caught Nightmare off-guard. Celestia closed the distance between them quickly, and quite eagerly began to pepper her opponent with swift jabs and powerful straights.

She felt alive.

Celestia followed up with a cross and jab combination which managed to begin pushing Nightmare backwards from the center of the ring. Her opponent immediately went on the defensive, guarding against the oncoming blows and looking for an opportunity to counter.

Celestia’s punches were hitting Nightmare's forearms more and more often, thumping flatly against toned flesh and hard bone. Nightmare winced from the punishment, and arms were getting numb from the constant barrage.

Her sun-themed opponent was picking up surprisingly quickly, and her punches were getting faster and more powerful. She struck hard, successfully nailing Nightmare's forehead with a stinging jab. Years of spectating had certainly thought Celestia a thing or two, or so she hoped. Nightmare dropped her guard for a millisecond to jab repeatedly at Celestia, but the sun princess began to bob and weave, avoiding the blows that were coming her way to present a smaller target for Nightmare to hit.

“Who’s slow now?!” Celestia taunted, barely missing an incoming shot and punching back in return.

Nightmare hissed as another blow thumped dully against her aching forearms.

Celestia’s mind and body was now working as one, putting her in the figurative ‘zone’ as she met Nightmare once more. Now, she was beginning to dominate the round.

But not for long.

Nightmare’s patience was wearing dangerously thin as Celestia grew cockier.

The bitch needs to put in her place.

Nightmare Moon was not a defensive fighter by nature, nor was she ever. When she fought, she aimed to destroy, and when she ended somepony, she made sure it hurt. Celestia didn’t seem to be horribly crippled in agony yet, and that was unacceptable.

Nightmare bided her time, dodging and guarding against Celestia’s onslaught patiently, occasionally grunting in pain when a shot or two slipped through. However, it wasn’t long before she found the opportunity to get back into the game.

Celestia misjudged a poweful hook, causing her arm to swing wildly off target.

“Fhh-Ahh!!!”

Nightmare’s glove hit her like a missile, nailing the sun mare painfully in the ribs. Celestia groaned as a sharp twinge of pain exploded in her side. Her ribs rattled from the blow, and a nasty bruise began to form where Nightmare had hit her. She dodged a second blow, but failed to see the uppercut coming.

Nightmare’s fist rocketed right between Celestia’s heaving breasts, cleaving and parting the two luscious melons aside to create a path that ended at Celestia’s chin. The punch sent her reeling back dizzily, but Nightmare took a step back instead of following her to take a breath and to recover from her earlier beating. Both mares took another step backwards and immediately raised their arms; guards held high and ready.

“Tired?” Nightmare huffed.

"That was…just a warm up." Celestia shook her head to clear it, and then tapped her gloves together.

“Go Princess!” Twilight shouted in support, and the crowd joined in.

“Come on.” Celestia waggled her glove tauntingly.

Nightmare grinned and accepted the invitation, returning to within striking distance.

The short breather was exactly what she needed, and Nightmare was back to being quick on her feet; moving with light grace but striking with the vicious ferocity of a manticore. She launched two jabs with a right and a hook with her left arm, smacking against Celestia’s own gloves and grazing her cheek as she tried to deliver her own blows as well.

Celestia grunted in pain as her stomach absorbed a blow from her opponent's fist, followed by a nasty left hook that twisted her head to the side. Her arms instinctively reached down to clutch her stomach, leaving her wide open. Then, Nightmare struck her on the cheek with what felt like the force of an oncoming freight train.

Celestia’s mouthguard was sent flying out of the ring, deftly smacking Twilight between the eyes before she could duck.

“Ew?”

The blow split her bottom lip, leaving a long trail of blood that ran down the side of her mouth and chin, in addition to throwing her off balance and forcing her to backpedal blindly in an attempt to stay on her feet.

Celestia remained standing while Nightmare had half expected her to topple over from the blow, much to her surprise. Shooting her opponent a death glare, Celestia spat onto the canvas, staining it red with her blood.

"Is that all, bitch?"

Nightmare furrowed her brows in anger at the taunt.

“We’re only getting started!”

Both mares went at it again; matching each other blow-for-blow, fueled by adrenaline and a healthy dose of mutual hatred. Every punch was returned in kind as both fighters angrily beat the living daylights out of each other, leaving nasty red welts and dark blue bruises whenever their gloves came into contact with flesh.

Lightly toned muscles rippled with effort under a sheen of sweat and tears as each mare pushed her body to the very limit; moving, striking and absorbing countless blows as the round dragged on.

They clinched once more when exhaustion claimed them, holding onto to each other and slamming their foreheads together with a loud clunk. One hand rested on the back of the head of the other, leaving their other hand free to throw punches into the lower body.

As they remained stationary, both found the opportunity to sneak in some extra burns.

It started off softly, at first.

Taunts and hissing insults were traded between the two in hushed tones and through gritted teeth as they exchanged hateful words and stomach punches like love letters.

Then, it got louder.

And louder.

A furious Celestia raised her voice to the point that the audience could hear her every word. Not willing to be outdone, Nightmare yelled back for the entire arena to hear, and soon, the Royal Canterlot voice was now being used to trade insults, much to the delight of the crowd.

"You were always the useless one." Nightmare shouted bitterly, slamming her fist into Celestia's belly, sinking deep into her stomach.

"Unfffgh!" Celestia groaned. "And you were always a miserable excuse for a villain!" Celestia repaid Nightmare with her own punch to the stomach.

"Ahhnn!" Nightmare clenched her eyes shut at the pain. "You don't have the guts to do anything but sit on that fat ass of yours and fuck your own guards!"

"At least I don’t stuff my vagina full with moon rocks!"

Nightmare's cheeks actually flushed at that one, and the crowd laughed at her reaction.

"How dare you!" She hissed.

Celestia grinned in satisfaction, despite the pain from her aching gut.

“At least I didn’t bore Sombra to death, prude.”

Celestia’s eyes widened for a split second, and then her lips curled into an angry snarl.

“Bitch! Sombra was mine!"

Nightmare finally smirked in triumph.

"Face it, princess. Sombra was never yours.”

Celestia narrowed her eyes dangerously.

“I fucked him better than you ever could.”

"TOO MUCH INFORMATION!" Twilight yelled in anguish in the background. She curled up into a little ball, and her tail sympathetically wrapped itself around her body for her to pet. "Too much...I need bleach…please…somepony!"

Her words went unheard as the two fighters continued their little shouting match.

"Fat-flanks!"

"Sociopath!"

"Royal slut!"

“Moon whorse!”

Celestia had just enough of Nightmare’s taunting, and decided it was time to really piss her off.

“I bet Nightmare Rarity would stand a better chance against me.”

The crowd ‘ooh-ed’ at that one.

Nightmare was shaking with rage so white-hot it could have ignited Tartarus twice-over and killed all of its inhabitants.

“Raaaagggghhh!”

Somewhere else in the dreamscape, Rarity was seated comfortably with a potential client at an upscale Canterlot eatery. She had just begun to munch on an exquisite watercress salad when her nose twitched several times.

“As I was saying, five dresses would be,” the pony paused and adjusted his monocle slightly. “I say, Miss Rarity, are you quite alright?”

“Y-Yes, of course, Fancy! Perfectly fi- BLARGHCHEW!”

Rarity sneezed the sneeze of a lifetime, and a spew of half-chewed leaves and saliva smacked into the pony sitting opposite her, killing the mood and the business opportunity.

Now, enraging a dark eldritch goddess was never usually a smart thing to do, even if it was to lure her into an elaborate set-up. A momentary lapse of good judgement on Celestia's part caused her to successfully infuriate Nightmare, but there was no follow-up plan on how to deal with the consequences.

WHUMP

“Daaarrgh!”

Nightmare began to put everything into her gut-busting punches, and Celestia was really beginning to feel the effects. Her gut was sore, and the heavy bruising just below her ribs was making it very hard to breathe. The unrelenting beating continued, and every blow smashed into Celestia's stomach like a jackhammer. Every hate-filled punch was an immensely satisfying one to Nightmare, as if vengeance for a thousand-year exile could be grasped in her clenched fist and driven deep into her opponent's bowels.

Celestia was damned sure Nightmare's glove would rip her in two and stick out her back like a scene from a gory horror flick if she didn't do something, quickly.

Another blow struck her hard, causing her to double over in agony.

She gurgled, holding her glove to her mouth in panic when she tasted the sourish, bitter flavor of bile. She was going to lose her dinner if Nightmare kept this up. Unable to match Nightmare's ferocity, Celestia began to desperately find a way to escape before her guts were reduced to mush.

She threw her fist again, this time aiming for a different target.

A quick jab to the throat caught Nightmare off guard, causing her to gasp in shock. Her eyes shot wide open as she reached up to grasp at her neck, allowing Celestia shove her away and put some distance between them.

Celestia began to slowly retreat to her corner in growing panic when the bell ended second round ended with a loud clang like a lifesaver.

Nightmare Moon was still clutching her throat painfully when the bell sounded, and she took the opportunity to shamble back to her corner, but not after threatening Celestia with vicious reprisal in the next round.

"Water...please..." Celestia groaned as she slumped weakly against the turnbuckles.

Twilight lifted a bottle to Celestia’s lips and squeezed gently. The stream of ice-cold water stung her cut lips, but the numbing sensation afterwards was worth it. Streams of excess water ran down Celestia’s chin and neck, and down her glistening bosom, prompting a shiver.

Across the ring, the two mares were already working away on Nightmare Moon; their soft, petite hands rubbing away the ebbing pain from various parts of her body. Twilight did her best, but was met with a violent twitch from Celestia every time she touched one of the many bruises that marked her body.

“Princess, I think I can see a pattern in the way Nightmare moves.”

Celestia was too dazed to pay attention.

“Princess? Princess?”

Twilight squeezed her mentor’s cheeks together. She swore she could hear a little squeaky noise somewhere as she did, but was distracted when Celestia coughed right in her face.

“Bleah!”

“Sorry Twilight.” Celestia groaned, moving a little and wincing at the little jolts of pain from different parts of her body.

Twilight wiped a little blood from her nose. “It’s okay…Let’s get you fixed up.”

She reached up with a soaked towel to dab gently at Celestia's lips, prompting another twitch from her mentor.

"So, how do I look?"

"Pretty horrible."

Celestia groaned. Two rounds in and she looked and felt like a bedraggled punching-bag. She shut her eyes tightly, trying to get rid of the fuzzy feeling that was beginning to cloud her, and waited for the next round to start.

Twilight watched her mentor in silent contemplation as she tossed a blood-soaked piece of gauze aside. Her mind replayed the previous two rounds with vivid accuracy, and she was nearly done processing the information in her head. There was one way she could help, but she just needed to make sure...

The bell clanged again, and round three began.

They met in the center of the ring again, furiously going at it once more. Their bare bodies were now covered in blood and bruises, glistening with sweat under the sizzling heat of the spotlights as they exchanged blows and frustrated cries. Twilight watched the unfolding carnage in rapt attention. She was getting little wet (a mild distraction), but her analytical mind continued to observe every movement of Celestia's opponent.

It had taken two rounds, but she was beginning to see a pattern in the way Nightmare moved. A swing, a jab, a duck. She watched how Nightmare delivered her blows and dodged incoming ones. Twilight did the math, and devised every possible outcome of the brawl.

If she had predicted right, Nightmare would throw a hook.

Wham.

Celestia's cheek took the full brunt of the blow, snapping her head to the right.

Correct.

She'd probably throw another one with her left.

Wham.

Celestia's head rocked to the side violently, but she recovered quickly and repaid Nightmare with a body blow.

Nightmare was going to jab.

Wham.

Twilight winced.

Correct.

Grabbing onto the ropes to balance herself, Twilight jumped up and shouted as loud as she could.

"Princess, break left!"

Celestia's ear twitched slightly as she picked up Twilight's distinct yell, and subconsciously, she sidestepped to the left. Nightmare's cross sailed past her, and the successful dodge left her wide open. Taking the opportunity, she slammed her fist into her opponent's unprotected cheek with a stinging jab.

"Duck!!!"

She ducked, and much to her (and Nightmare's) surprise, the punch flew right over her head. Celestia responded with a hook Nightmare below her breasts, knocking the wind out of her. Both fighters were moving fast, trading blows and muttering angry curses under their breath.

"And uhh...break right, right!"

Celesita awkwardly tried to sidestep the incoming blow, but it was far too slow and predictable. She paid the price with a nasty uppercut that rocked her chin and sprayed spit and blood onto the two fighters.

“Fffhhhhh!!!!”

"Sorry! …Crap. ..Crap." Twilight trembled, lifting a towel to wipe her forehead nervously as panic began to set in.

“Some help she is!” Nightmare taunted, dodging another blow.

Celestia growled and swung hard, knocking Nightmare’s head to the side. Undaunted, Nightmare launched a lightning quick counter.
Celestia raised her arms to protect her face, but Nightmare threw a hook aimed a tad bit lower, slamming her glove into her right breast. The impact was an incredibly satisfying one, and she revelled in the dull thump and the feeling of her clenched fist on the soft, yielding pillow.

“AAAAAAAHH!!!” Celestia screeched loudly, but in an incredible feat of resolve, hit back.

Nightmare’s guard was raised a tad bit too high as she didn’t expect Celestia to return the favor with interest.

It was a regrettable decision.

Celestia simultaneously smashed both her fists upwards into Nightmare's unprotected breasts in revenge. The gloves collided with two perfect, firm breasts, flattening the melons against her ribcage, knocking the air right out of her lungs.

"AHHHRRGH!" She exhaled violently with a loud scream.

Instinctively, both of Nightmare’s gloves reached downwards to cup her injured twin-prides.

“You did not just fucking punch me in the tits,” Celestia roared and launched a devastating cross, hitting Nightmare with enough force to splatter dewdrops of blood everywhere, coating much of Celestia’s face and chest fur. Nightmare reeled and wobbled, but more importantly, her arms dropped limply to her sides.

With a ferocious battlecry, Celestia launched a massive barrage against the punch-drunk mare. She began to pummel her violently, launching powerful hooks that snapped her head left, right, left and right again, followed by several straights that actually managed to leave her cross-eyed.

The twin suns on Celestia's gloves were dyed red with Nightmare's blood, dripping down in thick, heavy droplets. She heaved for air, gasping loudly as the increasingly bloodthirsty crowd urged her to continue.

She did not disappoint.

With another near-animalistic cry of rage, she delivered a vicious uppercut that sent Nightmare flying into the ropes. The queen of darkness hooked two arms around the top rope desperately, clinging on for dear life as her legs gave out underneath her.

Celestia rushed her quickly, tenderizing her vulnerable stomach with a barrage of uppercuts that forced Nightmare up on her tip-toes. When one hand loosened her grip on the rope to protect her body, Celestia began wrecking her pretty face instead.

She lost track of how many times she had struck Nightmare on the ropes. All she could hear was the dull thumps of leather on flesh, and the ringing cries of pain from the mare on the receiving end. Her lungs and muscles burned from the rapid loss of oxygen, and she was beginning to tremble from exertion as she continued to pummel her opponent.

With one last killer punch to Nightmare's gut, she backed off to recover by taking two steps back. Celestia put her arms up in preparation for another bout as Nightmare finally released her weakening grip on the ropes, pushing herself away as she did. Nightmare raised her arms slightly, but by the time they reached chest-level, she shuddered violently.

The crowd suddenly went silent, and the atmosphere was still.

Then there was an audible, wet gurgle, and a torrent of spit and blood spewed from Nightmare’s mouth. Her mouthguard, now stained red as well, dropped onto the canvas with a wet thump. Nightmare Moon slumped over groggily, and she dropped onto one knee.

There was a tense moment, with Celestia's guard still up, before the rest of Nightmare's body fell forwards. She had to resort to using an outstretched arm to prevent herself from completely falling flat onto the canvas, but she was down.

Celestia's eyes widened, and she felt a surge of triumph well up in her chest.

This was it! She did it!

"Way to go, Princess!!!"

Celestia turned to see Twilight with a huge, beaming smile filled with pride for her mentor.

"We did it, Twilight! We did it!!!"

Celestia faced Nightmare again, this time with the intention of a round of well-deserved gloating. She had just opened her mouth to sneer at her opponent when-

WHUMP

-there was a wet smack, and Celestia's facial expression twisted into one of unspeakable agony. Her mouth remained open, but her throat constricted and no sound could escape to tell the world of her horrific pain.

“Low blow!!!” Someone in the crowd gleefully shouted, and suddenly everyone was wooping.

Nightmare's glove had parted Celestia's glistening lips, impacting wetly with her delicate cunt. It smashed into her vaginal lips and swollen clit, sandwiching the ultra-sensitive organ between her hard fist and Celestia's even harder pubic bone.

With a soundless scream, she collapsed onto the canvas with her gloves clutching her groin.

The crowd went wild, cheering madly in approval of the low-blow.

A million things were rushing through Celestia's mind, but through the haze of addled thoughts and intense pain, she could only focus on one thing; the tiny voice that reverberated angrily in her head over and over again.

Fuck, fuck, fuck, fuck, fuck...!

Celestia curled up into a fetal position slowly, breathing harshly through gritted teeth.

"HEY!!! T...That's not fair!!! Where the hay is the ref?!" Twilight yelled.

"There is no referee." Nightmare stated as if it was the most obvious thing in the world.

Gracefully rising to her feet, she wiped the back of her glove along her cut lips and bleeding nose.

"One!" A booming voice echoed through the arena, followed by a round of cheers.

The count had begun.

"Oh no, oh no, oh no...!" Twilight whimpered.

"No." Nightmare ordered, and the announcer made a zipping motion with his fingers across his lips.

She began to walk slow circles around the downed sun princess.

"Get up, bitch."

Celestia replied with a quiet whimper.

"I said, get up!!!" Nightmare kicked her hard in the ribs, knocking the wind from Celestia's lungs and causing her to gasp in pain.

"I'm going to destroy you, nice and slow." Nightmare grasped onto Celestia’s thick rainbow mane and pulled harshly, forcing her to stand on her wobbly feet. "And I wouldn't mind having a crippled sex-slave either."

Celestia bit back the pain and soldiered on, unwillingly guided by Nightmare’s firm grip on her mane. Her scalp burned, but she was more concerned to find out she had trouble walking. For a moment, she was worried if Nightmare had fractured her pelvis. Once they were back the middle of the ring, Nightmare loosened her grip and shoved her away.

Celestia wobbled a little, and her knees nearly failed her, but she steeled herself once again. She raised her guard cautiously, focusing all her effort in trying to remain standing. Nightmare didn’t even bother to do the same; instead, she began walking in a slow circle around Celestia.

“I don’t mean to crush your hopes about winning,” Nightmare began, but paused mid-sentence. “Oh, what am I saying? Of course I do.”

“Stop yapping and fight me, bitch.” Celestia snarled wearily, clinging to whatever bravado she could muster in her current state.

Nightmare narrowed her eyes angrily and raised her guard, approaching Celestia.

Celestia’s heart was thumping so hard and fast it hurt, and every step Nightmare took increased chance that it would skip a beat out of fear. She gulped.

"It’s your deathwish.” Nightmare grinned, and her visage was made all the more terrifying by the blood running down her nose and lips.

Celestia's eyes widened.

WHAM

Nightmare thrust her entire body forward, moving with a speed that would have made even Rainbow Dash turn green with envy.

Celestia jabbed wildly, barely grazing her opponent.

On the other hand, Nightmare moved like lightning, delivering two, three, six, ten... Twilight gasped in horror, mentally counting the blows Celestia was forced to take. Fourteen punches hit Celestia, hard, alternating between her bloodied face and bruised body. She managed to guard and dodge two or three, but many of the hits succeeded in winding and dizzying her.

In a fancy display of showboating, Nightmare Moon didn’t even land the killing blow. Instead of a punch, she simply shoved Celestia back into her corner roughly like an opponent unworthy of an honorable knockout.

Celestia hit the turnbuckle of her own corner with a loud thud and a cry just as the bell rang. She arched her back as her entire body exploded in pain, and she slumped down onto the canvas before Twilight could even ready her stool.

Nightmare contemplated ignoring the bell to continue wrecking Celestia to finish her once and for all, but she was too exhausted to do so. She had put on an air of pride and confidence, but her body was not immune to the brutality it was subject to either.

She was going to drop, if she kept pushing herself, but she was skilled in not showing it. With one last glance and a satisfied huff, she returned to her corner.

"Princess!" Twilight yelped. Panic began to set in as she looked at the badly beaten-up alicorn.

Dark blue patches began to show as bruises marked her pristine white fur, now matted and messy with sweat and hints of blood from her bleeding muzzle.

"Princess...Princess, please talk to me."

The glazed look in Celestia’s eyes only exacerbated Twilight’s panic. She began to smack her mentor’s cheek lightly, eventually rousing her from her daze.

"There's no way..." Celestia weakly gasped. "I can't win this."

"Yes, you can!" Twilight cried. "You have to!"

“You know...maybe…maybe eternal night isn’t such a bad thing!” Celestia’s voice began to crack.

Twilight slapped her again, this time much harder.

There was a long, sullen silence.

“Twilight.” Celestia took a long, deep breath.

“…Yes?”

“Thank you.”

The pair sat in quiet despair.

"...Twilight?"

"Yes, princess?"

"I can't feel my legs."

"I know. I don't think I would, too, if she hit me like that."

She winced a little when she looked at Celestia’s slit. Her cunt lips were beginning to swell, and there was a nasty bruise around her clit. It was wet and glistening, too, making the organ all the more sensitive to touch.

“How bad?”

“It’s bruised and swollen, but no bleeding.”

Celestia breathed a sigh of relief, but there was still the matter of the crippling throbbing between her legs.

Twilight plucked the ice pack she was using earlier, looked at it, and then back to Celestia's slit with some hesitation. Celesita let out a long, tired sigh.

"Do it."

Twilihgt looked away and pressed the ice firmly against her mentor's cooch. ...Not exactly something she'd ever expect to do in her life, but...

"Graaaaahh, ffffff....!" Celestia bit her lower lip. No words could describe the feeling, but if curiosity needed to be satisfied, it was not very pleasant at all. "Damn it!"

"Are you alright?"

"No, Twilight, I am definitely not alright!" Celestia whined.

"Power through it!" Twilight snapped, much to Celestia's surprise.

"Sorry...sorry." Twilight winced. In a softer, more hushed tone, she continued. "I think I have a way to beat her."

"You do?"

"Yes...and I need you to listen very, very carefully."

Admittedly, it took Celestia a while to grasp the impromptu lecture, especially after the multiple shots to the head.

But the lesson was sound, and it was Celestia's only hope. She nodded slowly as she looked over Twilight and across the ring at Nightmare, and silently, she prayed to whatever deity that watched over fights.

Tartarus was only beginning.

Part 1 of 2

I'm so tired right now. :facehoof:
Who are you rooting for?

Prologue

The hallways of Canterlot Castle were bathed in the light of the evening sun bearing down from across the horizon. Massive windows that lined the side passages of the great castle filtered the rays to a more delicate, softer tone, allowing the viewer to peer out into the rest of the magnificent city below without being blinded.

Princess Celestia would have taken a moment, like on so many other days, to appreciate the view, but she was far too frustrated and walking far too fast.

"Sister, I must insist that you listen to-" a voice piped up from behind her, but she did not turn to look.

"Luna, please," Celestia cut her off. "You've said it yourself, she is still far too weak to pose an actual threat."

"Yes but..." The footsteps behind her stopped.

Celestia was tempted to continue walking, but with a tired sigh, she stopped and turned around. "But...?"

"Tia, this is Nightmare Moon we speak of. She is not a mare to be underestimated." Luna pleaded.

"I know, Luna. I know..." Celestia sighed wearily. "I just...I doubt that she could breach the castle, or our own defenses."

Memories of being blindsided by Nightmare Moon on the day of Luna's return from exile flooded Celestia's thoughts.

"Not this time, at least," she continued, watching a contingent from the Lunar Guard patrol the courtyards below.

"But-" Luna started.

"We will not be having this argument, Luna." Celestia stood firm.

Luna's neutral features slowly developed into a small scowl. Crossing her arms, she looked away and huffed.

"Fine."

Celestia's stance softened.

"Listen," she said in a whisper, extending her wings to engulf the smaller mare in a cocoon of warmth. "We'll be fine, alright? If she comes...we'll be ready for her. Every one of us."

Luna was caught by surprise, and her body stiffened for a moment before melting into her sister's embrace. Celestia had a point. With Luna's return, and the subsequent return of the Thestrals to the ranks of the royal guard, Canterlot Castle had become a bastion of security around the clock.

"I promise, Luna."

Her efforts rewarded her with a ghost of a smile from the night princess, and that was more than enough for her.

"Hm...I suppose we will. We..." Luna paused. "...I...will keep you safe as well, sister."

"Mirabilis es." She pecked her on the forehead. "Good night, Luna."

"Good night, sister."

With that, Luna turned in the opposite direction to conduct her nightly court, and Celestia continued on her way.

Princess Celestia sighed as she finally set the sun below the horizon. The streams of vibrant gold that entered through the balcony windows of her chambers dimmed and were replaced with beautiful silver hues of light that signaled the arrival of the moon. She had practically slumped over the moment her doors shut, feeling the weight on her shoulders lessen. Now, in the privacy of her chambers, she was free to do whatever the hay she wanted, which was exactly what she did.

She tugged on a cleverly placed string on the inside of her lavender dress, causing the silken work of art to gracefully slide off her curvaceous body and onto the floor in a heap. Next was a velvet corset that was practically ripped off in frustration, followed by a contented moan as her ample breasts popped free from their restraints.

Kicking off her high heels, she finished with a giggle as she slid off a daring strip of black fabric that was wedged between her sumptuous ass and her toned legs, wondering how the aristocracy would have reacted if they ever found out that their infallible Princess wore thongs to court.

By the time she had stripped off her garments and slipped on a pink lace nightie, the weight of the day truly began to take its toll on her. A mundane day, at best, but the workload had been steadily increasing as the holiday season neared.

After sitting through six grueling presentations and heated discussions on tax reforms, budget allocation and a debate on the need for more confectioneries for next month’s upcoming gala (Pinkie was there too!), saying she was exhausted was an understatement.

Her large, four-post bed beckoned to her as she removed her crown and necklace and levitated the golden regalia onto a stand. Sliding under the purple silk sheets, she let out another barely suppressed moan when she fell against the plush pillows and let her body yield itself to the soft, heavenly bedding. After a particularly loud yawn and stretch, she settled in, and drifted off into slumber…

It was an absolutely delightful two seconds of well-deserved rest before she was jolted awake. She opened her eyes in shock, but she was not greeted with the usual sight of the tastefully painted picture of Twilight Sparkle in a...questionable...pose that was stapled to the roof of her bed canopy. Rather, and rather remarkably, she found herself in an upright position, standing in the middle of nowhere.

There was darkness all around her, save for a bright light from above that was directly on her. She regained control of her body movements, moving her head from side to side and clenching her fists as a quick check.

She thought back…no, she had just turned in for the night, and no one had triggered her magical ward which would have woken her up the moment somepony stepped into her chambers. The other ward on her door would have been overridden itself and unlocked with a loud, audible bang, and her two door guards would have burst in within seconds.

There was no wind, no scent or sound, just an empty expanse of darkness beyond the small patch of light she was standing in.

Celestia presumed that she was in the dreamscape. It was a gut feeling, but she placed a lot of trust in her sixth sense. Having been dreaming for millennia, she had come to form a connection with the dreamscape just as much as her sister Luna had, despite her weaker affinity towards the ever changing dimension. That way, she could walk the world just as her sister could, but not shape it precisely to her desires.

But, she could think of something, and little effort on her part would set the dream in motion while the rest would come as a surprise.

Time for some fun.

She closed her eyes and stuck her tongue out the side of her lips in concentration, imagining herself in her throne room. She imagined herself seated comfortably on her plush, royal throne, free of responsibilities and the ever-scornful gaze of her courtiers. For that matter, she was also free of clothes.

She was stretching back lazily; her head against an overstuffed pillow, and her legs dangling lazily on the armrest of her throne. To her sides, bare chested stallions from her own personal guard waved large palm leaves and fed her cake, while in the center of her throne stood the centerpiece of her dream. Twilight Sparkle, all dressed up in frilly lingerie, danced next to a long, metal pole. Gyrating her hips to the slow beat of music played in the background, she shot Celestia a saucy grin as she pressed her crotch against the pole.

"Does this please you, Princess?"

Oh, yes.

With a delightful shiver, Celestia opened her eyes with a gleeful smile to greet her despicably naughty student, but her grin died the moment she was met with the same empty expanse of void.

It was then she took note of that the darkness surrounding her. Now, it seemed unnatural, and foreboding. It swirled with an odd movement that was disturbingly visceral, and it radiated an aura of malice. She had dreamed of darkness before, forlorn nightmares that haunted her as a filly, but certainly nothing like this.

She felt a chill run down her spine, and she realized just how terrified she was. There was one, and only one pony she would call on in a situation like this.

At last, she could resist no longer.

“Luna?!” She cried out into the darkness.

There was a brief pause, but then the world around her shifted in response. The inky blackness parted like a veil of water, moving aside and letting in much needed light. A loud noise echoed in the distance, like a heavy door slamming shut, and the telltale tap-tap-tap of slow footsteps made it clear that she was not necessarily alone.

The retreating darkness allows Celestia to see a little more, and in particular, a figure that was approaching her in the distance. She squinted to see properly, but once her vision adjusted to the sudden change in brightness, she could make out the pony that had stopped just a few feet away from her.

A creeping dread washed over her, sending a terrified shiver through her entire body. She gasped.

“Oh Goddess…”

“Why, hello, Celestia." Her voice was smooth and sweet like fine aged honey, albeit laced with venom.

Celestia's eyes went as wide as dinner plates and the mouth hung open, desperately trying to form a response as she watched the other mare begin to walk in a predatory circle around her.

"N...N...nuh...n..." Celestia blurted.

"Cat got your tongue?" The mare tsked. "I'm disappointed. You're usually quite the orator."

"Nightmare...Moon...." Celestia spoke in a barely audible tone.

The mare responded with a smirk. There stood Nightmare Moon, in all her terrifying and sensual glory. Celestia recognized her by her wispy, starry mane that drifted in an ethereal breeze, along with her draconic arctic-blue eyes, accented by the purple eye-shadow she used.

She had forgone her iconic crystalline armor and helmet completely, opting for a shimmering black dress that hugged her curves and taut, slender body. The dress parted along her hips to display her firm thighs and long legs, and similarly, a narrow opening just above the chest displayed her prominent cleavage through the near transparent material.

It sent a rather daunting message to Celestia that she wasn't the only sex goddess in Equestria.

"We bid thee welcome to thine worst nightmare." Nightmare quipped, mockingly curtseying to the sun princess and snapping her out of her stupor.

“ W..What do you want? W have you done with Luna?! If you hurt her again I swear-...”

“I've not hurt my beloved Luna," Nightmare sneered. "So fret not."

Celestia's eyes only narrowed in response. "Then why am I here?"

"There is the matter of something that needs to be settled between you and I."

"Ahh, petty revenge, now is it?" Celestia growled. Her horn began to glow as she charged her magic. "You forget, I have spells that can let me leave the dreamscape as I please. I'll be awake before..."

There was a pop, and a little fizzle of sparks, signaling a failed spell.

“Try again.” Nightmare smirked as she urged Celestia on.

“I…” Celestia closed her eyes and focused on her magic, only to find it completely unresponsive to her.

Crap.

Nightmare laughed wickedly. “Is there something wrong, Celestia?”

"What..did...you...do...?" She replied through clenched teeth.

"Foal," Nightmare gestured around her with her hand, eventually pointing upwards above her. "There is no magic in this domain. Only a ward."

True enough, a massive round glyph glowed green and purple, surrounded by rings of light and markings written in ancient Equestrian. Celestia blinked, flabbergasted as to how she had missed it in the first place.

Celestia snarled, her patience wearing thin. “Then what is the condition to break it?”

Nightmare still wore her grin. “Simple…This dreamscape will collapse upon itself and you will be freed if...you defeat me mare-to-mare.”

Celestia hmphed haughtily.

“What? Afraid to get physical with me in the real world, Nightmare?” Celestia taunted.

"Oh, perish the thought, Celestia. You are in my domain now, and..." Nightmare shot a sideways glance at her nemesis. "I can sense your fear."

It was true, to say the least. Celestia's legs trembled slightly, and she struggled to maintain the confidence in her posture and voice. She wondered how long she could last before her body did something she would regret.

"Now...should you emerge victorious, you will awaken." Nightmare turned to face Celestia directly. With a wicked grin, she continued. "Should you be defeated, you will remain here for all eternity, and not even Luna will be able to break you free."

“…No….” Celestia’s eyes widened in fear.

Nightmare began a slow and steady saunter towards her prey.

“Yes. There is no other choice, Celestia! Fight me, or be tormented forever!”

The dark mare had reached within striking distance of Celestia. One more step, and Celestia gasped the moment Nightmare pressed herself against her counterpart in a display of pride and confidence. Bountiful breasts were first to push against each other, and in the dangerously close proximity they were in, both mares found themselves getting moist as they strained against one another.

"Your choice." Nightmare whispered.

Celestia stifled a moan, but in a show of defiance, balled her fists angrily. There was no way in Tartarus that little moon whorse was going to trap her in a damned coma.

"I accept your challenge, Nightmare Moon!” There was too much on the line here to back down, both for Equestria and her own pride.

Nightmare grinned, and she licked one of her razor sharp canines in anticipation.

"Good."

She snapped her fingers, and the world went dark once again.

The Squared Circle (Pt.2)

The spotlights of the arena were beating down on both fighters as much as they beat down each other at this point, and not even the large amounts of ice Twilight was applying was of much help. Celestia huffed as she wiped another heavy bead of sweat from her forehead before it could irritate her eyes. The other droplets simply dripped from under her muzzle, landing and trailing along the perfect, round contours of her shapely breasts down the rest of her bruised, aching body.

She wasn’t out for the count just yet, though.

"Round four, ladies and gentlecolts!"

The announcer’s call was followed by the clanging of the bell resounding across the arena, and there was a thunderous boom of cheers as the two fighters met in the middle once more. Celestia had stumbled out of her corner on wobbly legs, still reeling from the after-effects of Nightmare's low blow, but she did so with a fire was still burning strong in her chest. She set herself up in a good stance, and was more than ready to beat the snot out of her opponent.

She could do this. She was going to win this. The fiery confidence only got hotter when-

“AAAAAAAAHHHHH!!!!!!”

It grew too hot for Celestia to handle. Nightmare aimed low, and Celestia’s chest exploded in pain as a shiny purple glove plowed into her right tit like a speeding train. The blow flattened the soft, plushy breast against her ribcage and knocked her entire body sideways, throwing her off balance.

One hand reached down to cup her chest, leaving her open again. Before Celestia could curse at her instinctive reaction, Nightmare had already thrown the second punch, cuffing her on the upper-right side of her head. Her ear was harshly twisted from the blow, causing her to squeal in pain.

She bent her body low, but held her guard up, saving her face from the full brunt of another uppercut. Nightmare seemed to swing with uncanny power, sending Celestia reeling backwards and leaving her with aching arms. The sun princess took a step back to center herself, and her stance allowed her to absorb another powerful cross from Nightmare.

She rolled with the punch, snapping back to put some distance between herself and Nightmare, before coming back with a devastating straight of her own. The blow slammed hard into Nightmare’s sensitive snout, splitting her lower lip, snapping her head back and leaving a sticky trail of spit and blood on Celestia’s glove when she pulled back.

Nightmare blinked away the pain and took a step back to cock her fist back for another powerful blow, growling angrily as she did, only to receive a lightning-fast jab to her wounded snout again. She yelped loudly when the stinging blow impacted, and she lost her focus. Celestia, having disrupted the incoming punch, followed up with another fast pair of left-right jabs, hitting Nightmare in both cheeks and causing her head to twist right and left.

With a grunt, Nightmare took another step back. She was retreating! Celestia, both eager and desperate for the opportunity, rushed the other mare and closed the distance quickly. She moved a little too quickly and wobbled in her stance, and Nightmare grinned like a frightening Cheshire cat. Celestia had walked right into her trap. Nightmare had the millisecond opportunity to center herself when she retreated, and was more than ready to strike at her overbalanced opponent.

Celestia was met with two blistering jabs that struck her below the right eye and left cheek, causing her to cry out and reel backwards. Before her foot even touched the mat, however, Nightmare shocked her with a terrific uppercut right below her breasts. The glove thumped hard into her aptly-named solar plexus, knocking the wind out of her and causing her to double over.

Nightmare followed up with another uppercut, this time smacking Celestia square in the face. The blow impacted hard, lifting her head and entire body back upright and sending a nasty gush of blood into the air.

“Urrrggghh!!” Celestia groaned, dizzily stumbling to the left in an attempt to get away from Nightmare. The dark mare followed, like a bloodthirsty predator with the opportunity to rip her prey to shreds.

Desperately, Celestia swung low, attempting to cripple Nightmare with a shot to the groin, but the other mare stepped aside quickly to avoid it.

“You want to play like me, Princess?” Nightmare cooed, pursing her lips as she mocked her nemesis. “Does your overused twat still hurt, whorse?”

“No, but yours will!” Celestia yelled angrily, rushing forwards and slamming her fist into Nightmare’s lower body. The glove smacked hard into firm flesh, and the momentum carried the weight and power of the blow all the way to the back of Nightmare’s body.

“Ahhhrrrgghh!!!” Nightmare screamed as white-hot pain ripped through nether regions. Her foal-makers took the full brunt of Celestia’s glove, causing her legs to buckle violently in reaction. The shocking blow to her ovaries also forced her to double over in shocked anguish, leaving her wide open for Celestia to continue wailing on her.

Celestia clenched her fists together and raised them high above her head like an executioner ready to swing an axe. She jumped high, and with a little help from gravity, hammered her fists simultaneously as hard as she could right in the back of Nightmare’s head. There was a dull thud, but no sharp crack because of her gloves, much to Celestia’s disappointment.

Nightmare tried to rise from the canvas groggily, but Celestia would be having none of that. The dark mare had just about to balance herself on all fours when, in an unexpected move, Celestia raised her leg up high above Nightmare. She shifted her body weight, and put everything into a stomp that would have annihilated every insect within a ten foot radius because of the shockwave alone.

“Aaaagggghh!!!!” Nightmare screamed as Celestia’s white boot smashed into her back, digging in brutally between her wing joints. She was practically trampled onto the mat, and her pained cry only got louder when her breasts were flattened against the hard surface. The more Celestia stomped, the more Nightmare howled in agony, body jolting violently from the impact.

Celestia stomped hard again, only to cry out in surprise when her laced boot struck the mat. Nightmare had rolled over to the side and rose to one knee quickly. She cocked her fist back all the way, and just as Celestia turned to face her, foot raised high for another kick, Nightmare launched her fist upwards right into the plump, fuzzy white mound between Celestia’s legs.

The blow actually lifted her off her feet, and for a moment, the sun princess was hanging above the mat with Nightmare’s glove buried deep within her glistening folds, juices dripping and sliding along the shiny purple glove. Nightmare held the tortured goddess in that position, holding Celestia upright with her single glove. Her lightly toned bicep strained with immense effort for a few agonizing seconds, before she let Celestia go.

The few seconds were like several lifetimes of horrific agony for Celestia. She couldn’t scream. Nothing would come out, and all she could do was gaze into blank space with glassy eyes. Part of her brain froze from the sheer amounts of pain overloading her system, practically paralyzing her as she dropped onto her knees, clutching her privates for the second time that night. She gasped for air, and her chest heaved from the effort. Nightmare was treated to the incredibly titillating sight of Celestia’s luscious tits bouncing up and down, made only better with the little whines of pain she made when she exhaled.

Nightmare swung her now-slick, sticky glove hard, smashing into the side of Celestia’s cheek and knocking the sun princess flat onto the canvas.

"One!" The announcer yelled, but Nightmare waved him off again, prompting an annoyed huff from him.

"Ending this match so soon would be a waste." Nightmare tsked as she strut around the ring tauntingly, waiting for her opponent to rise.
She took her sweet time riling up the crowd as she raised her arms triumphantly, and seeing that Celestia was unlikely to get up anytime soon, she left her whimpering on the ground. Nightmare rested her back on the ropes to take a breather, and a smug smile formed on the lips as she relaxed her tense body, letting the ropes take her weight as the crowd continued to cheer. For now, she was content to watch Celestia writhe on the ground in agony.

Celestia would have already gone past the ten-count, had it not been called off, and she considered herself lucky that Nightmare's cockiness gave her precious time to recover. The pain from the throbbing bruise on her cheek was nothing compared to the agony between her legs.
Her knees were like jelly, and any attempt to move her legs resulted in a surge of white-hot pain that paralyzed the rest of her body.

But ever so slowly, she began to crawl pitifully towards the ropes, one glove after the other. She grit her teeth in sheer effort as she dragged herself across the ring. Her arms burned with effort, made only even worse by the need to lift her upper body up as well to prevent her breasts from rubbing against the rough canvas.

Nightmare yawned by the time Celestia slumped onto the bottom rope and dragged herself up, just in time for the bell to ring. The round was over, and Nightmare, despite the punishment she had taken, had absolutely dominated it.

Twilight was yelling from the corner, urging Celestia to return, but there was one thing she needed to do first. She, of all ponies, knew her body best and to what extent of Tartarus it could be put through. There was no way she could take any more of Nightmare’s powerful blows. Her head throbbed, blurring her vision every time her heart sent another rush of blood and adrenaline through her body, and she was damned sure another shot to the head would knock her out cold. Her body was already sluggish and weak from exertion.

She pulled herself as far out of the ring as the ropes would let her, and she waved the announcer over with growing desperation. With a curious look, he made his way over to Celestia, who the whispered in his flickering ear as Nightmare looked on with mild interest. His eyes widened, and he turned to Celestia in surprise. Celestia didn’t say anything more, and only nodded her head resolutely.

There was a brief pause, before he sprang to action, scrambling for the mike.

"Ladies and Gentlecolts, I have an announcement to make!"

Nightmare Moon brushed her seconds aside and gave Celestia a cocky grin. "Giving up, Princess?"

Celestia ignored her and pointedly began mentally preparing herself for what was to come. She'd have to sacrifice one part of her body, for the sake of the more important bits, and as the announcer’s voice continued to reverberate around the arena, she painfully made her way back to her corner.

"Princess Celestia has issued Nightmare Moon a formal challenge!"

The crowd oohed in surprise, and Nightmare narrowed her eyes in suspicion. What was Celestia playing at…?

The sun princess made it to her corner, and Twilight got to work in dressing the bleeding cuts across her face from the savage beatdown. It was getting harder to wipe the blood away from her pristine white coat, but Twilight was able to clear up what she could with cold water and a towel.

She was just about to begin help with her mentor’s slightly swelling cheek when the announcer boomed again.

"For the next round, only blows to the chest region will be allowed!"

There was a low murmur in the crowd, and Twilight’s ears twitched slightly. She looked right at Celestia, who opted to look away instead.

Unsatisfied by the reaction he was getting, the stallion continued dramatically. "…which means both mares will be putting their most bountiful assets on the line!"

More silence.

The stallion groaned.

"Tit-blows only!"

The crowd cheered. The prospect of two busty mares putting their tits on the line was certainly a titillating one, and the audience roared in approval. Nightmare's jaw dropped a little, as did Twilight's.

"Princess, have you gone mad?!?!?" Twilight yelled, shaking Celestia so violently her mane whipped back and forth. “What the hay are you thinking?!”

It was the sacrifice of the ages, but Celestia needed the precious time to recover from the brutal shots she had taken to the head and rest of her aching body. She crossed her arms over her bountiful tits, wincing as she felt the light bruises there.

“Twilight…” Celestia griped.

“One condition.” Nightmare’s own amplified voice resounded from across the ring, catching the attention of everypony. With a nasty grin, continued. “No blocking. Take it like a mare.”

Celestia gulped, but nodded nonetheless, much to Twilight’s dismay. Celestia ignored her student’s panicked gibbering for the time being, so she could narrow her eyes threateningly at the other mare, slamming her gloves together as she stared her down. No going back.

DING!

Both mares approached each other in a flurry of wild punches. Offense had become the only form of defense now as they ripped into each other with lightning-fast jabs, not wanting to waste precious time preparing more powerful swings and straights. Celestia’s gamble had saved her head and lower body for the time being, but she soon found herself wondering if she had made the right decision as her tits were furiously peppered by harsh, unforgiving jabs from Nightmare’s fists.

She gasped at the abuse her bust was taking, but she was able to give back just as much as she was receiving. Their tits bounced up and down as they were smacked around, leaving both mares wincing and teary eyed with every stinging blow. Celestia launched a one-two combination to strike Nightmare’s chest, which was left wide open for her from the earlier agreement. Nightmare, however, switched tactics.

She slowed down on her offensive and began swishing around the ring, deftly avoiding many of Celestia’s jabs, and when her punches did connect, they merely grazed Nightmare’s succulent mounds.

Nightmare was too fast, and Celestia began chasing down a foe that was gradually sapping at her strength. She desperately needed something to throw her opponent off to give her time to really slam her fists into those two meatsacks Nightmare called tits. She braced herself and waited for an opening. Both fighters continued their little dance, jabbing and retreating, rinsing and repeating until Celestia found her opportunity.

Celestia feinted, tempting Nightmare to dig her heels in and launch a powerful straight to counter the blow that never arrived. She swung, hard, and Celestia sidestepped the punch in one smooth motion, before she launched herself at Nightmare. She slammed her tits into Nightmare’s own pair, causing both of them to cry out at the sudden jolt of pain and pleasure.

Nightmare was caught off guard by the Celestia’s boldness, even more so when the sun princess shoved her backwards. She stumbled and lost her stance, and that was all Celestia needed. She took her time to power her swings, and soon she was delivering explosive lefts and rights into Nightmare’s assets.

The dark mare howled in pain at the sudden increase in ferocity of Celestia's punches, but responded in kind with her own fiery blows. The sun princess had made a terrible mistake in trying to outpunch Nightmare, and she was paying the price bit-by-bit as she was forced backwards from the barrage of angry punches.

"You're a foal, Celestia!" Nightmare snarled as she pummeled the sun princess' melons with vicious fervor.

To add to her torment, Nightmare started twisting her glove just as she landed her blows, eliciting even louder loud screams from the sun princess. She hit her again and again, pounding the royal tits with the kind of force that would have ruptured punching bags. She mixed quick jabs and powerful uppercuts, forming a solid, unstoppable barrage hell-bent on destruction.

Finally, Celestia’s tits could take no more, and when Nightmare swung a terrible haymaker to the side of her right breast, her swollen teat released a long stream of fluid across the ring upon impact on the tender flesh.

Celestia screeched and backed away like a wounded animal, clutching her wounded breast in her gloves protectively. She groaned in agony, cupping the rapidly swelling right tit in her gloves and trying to nurse it gently.

"Oho! What's this...?" Nightmare stopped her assault to laugh snidely as she inspected her rather wet glove.

From outside the ring, Twilight watched in bewilderment as part of her face was drenched in white liquid. A tongue tentatively moved from Twilight's lips to the tip of her muzzle, tasting the warm...milk?

“Woah.”

Milk was dribbling from her right nipple after the last punch, contrasting against the color of Celestia’s bright pink teat. Crotch torture aside, the shots hurt Celestia more than anything she had felt in her incredibly long-lived existence, both physically and mentally.

“Here’s what’s going to happen, Princess.” Nightmare snapped Celestia back to attention by thumping her gloves together loudly.

"First, I'm going to tenderize those udders," She hissed as she stormed her way towards Celestia with her fists up, "-and then, I'm going to milk them dry."

Celestia couldn't help but shudder at the threat. She didn't lie to herself; it was terrifying. But she'd faced a lot of terrifying things in her long, long life. A dark goddess hardly made it that high on the list.

Another blow slammed into her already leaking right tit, causing Celestia to scream. Nightmare was moving up that list pretty fast. She dodged a second incoming missile, watching it whistle past her just inches away from her chest. Nightmare tsked and tried to launch a third shot, but Celestia managed to counter with an uppercut that nailed her right between her breasts. The blow smacked hard, but it only enraged the other mare even more.

Celestia was desperately wishing she had her armor on, especially the enchanted breastplate. Especially. The. Breastplate. She’d been into countless battles, yes, but certainly never without any armor, or clothes, for that matter. Wishing did little good when Nightmare struck her again, making sure her gloves smashed as far as they could through the melons and then viciously twisting her fists left and right in an attempt to really destroy Celestia’s tits.

The blows were beginning to impact her breastbone and ribcage as well, leaving her in wheezing and sending her into coughing fits every time she was hit. She was in excruciating pain, and all that she could think of now was trying to get away from the bloodthirsty mare that was out to crush her melons.

Nightmare backed Celestia into the ropes and continued a good, long minute of smashing into her tits and making her scream until her voice went hoarse. Finally, with one last thundering smash into Celestia’s bruised tits, she backed off to inspect her work.

Celestia looked down groggily at her gorgeous breasts, now heavily bruised and lactating. The fur on her chest was matted, curled, and stained red with blood and her own milk. She sight horrified her, and she would have fell onto her knees had she not been hanging onto the ropes for dear life.

Nightmare found the sight both amusing and arousing. Already exhausted from the beating she had inflicted on Celestia, she switched tactics and immediately began fondling Celestia's breasts with her gloves instead.

The sun mare jolted and gasped in shock, to which Nightmare grinned. She made sure to squeeze them both tightly and brush the rough laces uncomfortably against the other mare's hardening nipples, deriving her of any pleasure from the act. Celestia bit back a pained cry, shaking her head from side to side in disbelief. Trying to move her arms was futile, and she would have collapsed onto the mat if she let go of the ropes.

Despite her arousing need for wanton destruction, Nightmare’s own sense of curiosity prompted her to bend over and give Celestia’s tits a long, lavacious lick with her tongue as she continued to squeeze them.

“NNnnnhhh!!!” Celestia bit back a squeal at the wet, warm sensation on her teats. The pain and burning sensation did not give way to arousal, making Nightmare’s ministrations only painfully unpleasant to bear.

Nightmare was focusing on Celestia’s right tit, pinching the rock-hard nub between her front teeth, while her gloved hand wrapped around both breasts and squeezed firmly. She was rewarded with a long spurt of Celestia's mare-milk, not unlike a burst of painfully held-back stallion jizz that shot straight into her waiting mouth.

It was sweet to the taste, with a rich, creamy texture and had very pleasant warmth. Nightmare Moon swirled the ambrosia around her mouth appraisingly before swallowing with a hearty gulp.

She’d compare it to fine wine, and it was certainly…something. Her ears perked ever so slightly, and she licked her lips. Milk straight from the tits of a goddess was certainly not something that even she was privy to taste.

"Not bad at all, milkmare." Nightmare sneered as she continued to suck greedily from alternating breasts, occasionally pausing to lap at Celestia's extremely stiff, throbbing nipples.

"Ahhnnn...!" Celestia moaned loudly, and Twilight whined from afar, desperately wishing to be in Nightmare’s position.

When Nightmare had her fill, she pulled away from Celestia’s teat, but not before making sure to scrape alongside the entire bright pink nub with her teeth as she did, causing Celestia to yelp loudly.

Nightmare flipped her around and slammed her hard into the ropes, pressing her throat against the top rope. She then twisted Celestia’s arms back, entwining them with the elastic ropes and keeping her trapped there. Her globes were sticking out from between the ropes like a sacrificial offering to the dark goddess. And they were.

As Celestia remained suspended by the ropes, Nightmare snaked her hands around from behind and began to grope and fondle her tits roughly. She squeezed each shapely melon as hard as much her gloves allowed her to, which was followed by vicious twisting and tugging. All the while, Celestia was moaning and yelping in a confusing mix of agony and arousal.

“That was delicious…but it would be terrible of me to not share this bounty with my subjects, no?” Nightmare whispered in Celestia’s ear.

“What..? Wait…No…No please..! Noooo!!!!!”

Nightmare ignored her pleas and squeezed even harder, to the point that the lovely alabaster globes turned to a nasty shade of blue and purple, with just enough applied pressure to send two long jets of milk flying out of the ring and onto the spectators beyond the barriers.

The spray of Celestia's warm milk was met with a variety of reactions from the front row as it rained down on the audience. A few tried to get a once-in-a-lifetime taste of the milk of a goddess (they were not disappointed), others winced, but the reaction was largely in favour of the madness. Some began to chant Nightmare's name loudly, prompting her to squeeze Celestia's tits even harder to reward her adoring fans with another shower of delicious cream.

As she continued to squeeze and twist Celestia's melons with increasing fervor, Nightmare began to thrust her powerful hips into her opponent’s wonderfully cushy plot and mound as well. Her solid lower abdominal muscles slapped hard against Celestia's perky ass-cheeks and glistening marehood in a similar way a stallion would take a mare from behind. She slammed into her, hard, as if she were rutting the living daylights out of her, adding to the humiliation.

Celestia screamed as she was rocked forwards repeatedly, until her knees wobbled and her voice cracked. After several minutes of the humiliating torture, she began to sob. She hung her head low and her rainbow mane covered much of her face as she endured the pain and embarrassment she was being put through.

Eventually, Nightmare grew bored, and her hips were beginning to tire. She twisted Celestia's arms just as painfully to unwind her from the ropes, and then flipped her around again. Nightmare shoved Celestia back against her ropes again so she was facing her directly. With a grin, she cupped the underside of Celestia's swollen, bruised tits and proceeded to angle them upwards before squeezing hard, causing two geysers of her own hot milk to hit Celestia in the face.

"Noo..." Celestia groaned, only to be interrupted by a splatter of cream that caused her to start sputtering. She blinked harshly shook her head from side to side to clear her vision, sending droplets of sweat and milk around her. Nightmare continued to grope Celestia's tits, alternating between rough twisting and squeezing.

"Ahhhhnn!!!" Celestia let out a loud, throaty moan. Weakly, she grasped at Nightmare's pawing gloves, attempting to push them away.

"Slut...you like this, don't you?" She hissed, viciously twisting Celestia's tits as she did.

“No…!”

“Stop lying.” Nightmare reared back and began slamming her fists into Celestia’s abused tits again. She was rewarded with an agonizing scream from the sun princess, much to her satisfaction.

The force of the blows pushed Celestia against the ropes, and the elasticity shoved her forwards and onto her knees, mercifully removing Nightmare’s two targets from her line of sight. Celestia groaned, latching her hands around Nightmare’s curvy waist and hugging her tightly like a buoy to stop herself from collapsing onto the mat.

Nightmare, in all her arrogance and ego, lifted Celestia back up and shoved her own marvelous pair of tits in her face. “Remember these well, Princess.” She mocked as she rubbed herself against Celestia’s snout. “Soon, they will be the only greatest pair in Equestria!”

“Over…my…dead…body!” Celestia snarled under the weight of Nightmare’s melons, and she wasn’t very happy at the prospect of having her annual ‘Best Tits’ title being taken from her. With a surge of strength and rage, she opened her maw wide, and chomped down as hard as she could.

"Aaaarrggghhh!!!!" Nightmare howled and tried to pull away, only to find herself still trapped in Celestia’s arms. She began to rip into Nightmare’s breasts like a wild animal, repeatedly biting and scraping them with her teeth, leaving long trails of scratches and bite marks before shoving her away.

Nightmare looked down in horror to see a mish-mash of angry red marks on her breasts, along with a streak of blood run down her swollen left tit. Celestia took advantage of Nightmare’s dazed state and prepared to launch a counter-barrage while Nightmare was still off guard.
It was risky to expend so much energy in such a short time, but she was willing to take the chance. After a deep breath of air, Celestia crouched, ever so slightly, and she yelled, letting loose a volley of powerful swings and jabs that hit her disoriented opponent point-blank in the knockers multiple times.

Nightmare yelped at the sudden onslaught, and her vision was begun to blur. She tried to move back and sidestep, furiously blinking as she did, in an attempt to clear her tear-filled eyes. Celestia was having none of that, and she swooped in like a hawk after her prey.

She slammed both fists into the sides of Nightmare's breasts simultaneously, causing them to meet in the middle mash against each other and jut out from the pressure. Nightmare screeched bloody murder at the pain, but Celestia was only getting started. She kept her hands where they were, and proceeded to push down harder and harder, to the point that little pearly beads of milk began to form at the tips of her opponent's dark purple nipples.

"Stop...!" Nightmare squirmed under Celestia’s brutal hold and tried to retreat even further.

Payback time.

An insanely powerful cross smashed into Nightmare's left tit, resulting in a messy explosion of sweat and milk that splattered onto both mares. Before she could even scream, a second straight slammed into her other tit to compliment the other, with the same wet and painful conclusion.

Nightmare's natural black fur could not do much to hide the dark purple bruises that were beginning to form on her tits, and Celestia was quick to slam her fists into them repeatedly. Celestia made sure that Nightmare's tits took the full brunt of the blows by digging her gloves in as deep as she possibly could into her opponent, and, having learned from Nightmare, twisted her fists in upon impact as well.

It wasn’t long before Nightmare’s gaze drifted over past Celestia to the point that she was lazily staring into blank space. Her jaw hung open loosely, and the rest of her body teetered back and forth groggily.

Twilight cheered. Finally, the tide was turning!

Celestia grinned at the sight, and seeing that Nightmare was no longer a threat to her, she went ahead and cupped both opponents her tits with her gloves, and began squeezing until a soft spurt of milk erupted from both her purple nubs. Then, she leaned down to take a lick, followed by a long, loud and messy slurp.

Nightmare simply looked down in utter disbelief at the sun goddess that was suckling on her teat. Celestia shut her eyes thoughtfully as she sucked and lapped away. It was a lighter in taste, not as full and creamy as her own (Oh, she knew), but it possessed a delicate sweetness in its own right. Nightmare just stared at her in utter disbelief when she pulled back with milk dribbling down the side of her mouth.

Celestia smacked her wet lips, and then shrugged indifferently. “Meh. Not so great.”

And then, with a disturbingly feral grin, she proceeded to continue pounding the fuck out of Nightmare's tits.

By the time Celestia was really done with her, Nightmare was sprawled on the mat, moaning in agony. Her proud breasts were now swollen, bruised and battered punching bags. Her two engorged, purple nipples were leaking milk like a broken faucet. Rising on all fours, she began crawling towards the ropes to help herself up when Celestia triumphantly sat on her back, much to her disbelief.

Without another word, she bent down and snaked her hands around Nightmare’s battered chest. Nightmare had only one second to squeak before Celestia began to squeeze her opponent's tits for all that they were worth, milking her like a cow in front of hundreds of spectators. Nightmare moaned helplessly as spurt after spurt of her milk hit the canvas, but her aroused moans slowly turned into pained yelps and cries as Celestia began to squeeze her harder and harder.

Celestia continued to milk her in that position, and after several minutes of pinching, squeezing and screaming, the sound of milk spurting onto the growing pool on the mat stopped. Celestia piqued in curiosity, looking down at the pool and back at Nightmare's tits. Little droplets of milk were dripping out from her swollen teats, but that was it. She frowned and squeezed them hard, prompting a shrill cry from the dark goddess. Nothing was added to the pool of tit-milk.

Eventually, the perky nubs on Nightmare's melons could give no more, despite Celestia's insistence. She pinched them hard and squeezed roughly again, forcing a long, drawn-out scream of pain from Nightmare. After a minute of even more abuse, Nightmare sobbed. Celestia had milked her dry.

She let go of Nightmare's drained milkbags, tugging hard as she did. Then, she began to rock her hips. Nightmare whimpered, and the motion caused her to lose her grip on the canvas. Her gloves slid across the wet mat, causing her to fall onto her tits and face, with all the weight of the sun behind her. There was a loud whap and splash that sent milk and tears across much of the ring.

"Is that all you have in those sacks of meat?" Celestia sneered, and Nightmare replied with a whine.

Wow, it felt good to play rough, Celestia surmised. She wasn't just done yet, and she flipped Nightmare onto her back. She lifted Nightmare’s head up, and forced her snout right into her own alabaster tits.

"Since you loved it so much..." Celestia snarled. "Have some more!"

Nightmare opened her mouth to protest when Celestia shoved her teat all the way in and squeezed.

“Glrrk…!”

Nightmare let out a strangled gargle and tried to push away weakly. Celestia continued to squeeze, sending another long spray of warm, creamy milk down her opponent’s throat. She hooked her other arm around the back of Nightmare’s head and used her now free hand roughly clamp onto her snout instead, preventing her from breathing.

Nightmare began to panic, desperately swallowing what she could until her lungs burned. It was not long later that, she choked and gagged as the unwelcome fluid went down the wrong passageway, causing it to dribble messily out of her nose and mouth.

“Nncckk…..ngghh….! Gllrrhhkk….”

She was practically drowning in Celestia’s breast milk when the bell saved her, ending the round with a loud clang. Satisfied, Celestia pulled away and left Nightmare on the wet floor, coughing and sputtering as she gasped for precious, precious air. Celestia rose victoriously and strut back to her corner in time to the cheers of the crowd, but not before kicking the downed Nightmare in the flank nastily just because she could.

The rest period was uneventful, save for the particularly loud yelps from both corners of the ring as Celestia and Nightmare were tended to with a mountain of ice packs. Somepony had to climb into the ring with a mop to clean up that particularly large puddle of milk in the middle and the rest of the mess that turned it into a slippery deathtrap. Other than that, the swelling had gone down, the rules were back to normal, and both mares prepared themselves for another round of hell.

"Let's give it up for round six, ladies and gentlecolts!!!

The bell clanged again to start the sixth round of the match, and a very, very angry Nightmare immediately rushed Celestia before she could even reach the middle of the ring, catching her off guard with a cross and uppercut combination. Celestia half-expected to take advantage of Nightmare’s rage and play a little game of cat and mouse, but she found herself trying to deal with a vicious tigress that didn’t stop trying to maim her.

Celestia deflected the first punch easily enough, using her raised forearms to take the blow and moving her body so she could redirect it, but the uppercut smacked her hard in the ribs, leaving a nasty bruise that was visible on her white fur. The sun princess responded with a jab to Nightmare’s head that connected with a thump, hitting her hard right in the kisser, but Nightmare hit back with a jab that flew right into Celestia’s right eye.

The blow jolted her slightly, but it was enough to leave a nasty cut above her eyebrow. Celestia whined and tried to nail her opponent with a haymaker, but Nightmare was faster. She punched her in the right eye again, but this time, she twisted her hand ever so slightly to allow the thumb of her glove to jab Celestia.

“Ahhhhoww!!”

She shrieked and twisted her head away. Her magenta iris became increasingly surrounded by reddish-pink as her eye watered in response to the poke. She blinked furiously in an attempt to regain her vision, and luckily, she could still see despite the stinging pain.

She looked back just in time to see Nightmare back away a distance from her, guard still up, but this time, with a sly smile on her bloodied face. Nightmare spread her long, gorgeous wings and flapped them lightly to warm them up, before the powerful wing muscles shifted and thrust downwards in a single, fluid motion, sent her rocketing her forward with blinding speed. The ring ropes moved from the back-blast of wind, and in a spectacular display of overkill, she rushed Celestia and plowed her outstretched arm into her stomach.

The disemboweling punch practically gutted the sun princess, causing her to double over in a bout of bloody, hacking coughs. Celestia was thankful that she hadn’t expelled anything else, but it was short lived when Nightmare followed up with an uppercut into Celestia’s ribs again. Celestia’s chest tightened uncomfortably to the point that she couldn’t breathe properly, and she knew she was in serious danger.

In a frantic move, she lunged forward to clinch with Nightmare, but this time, her hands went straight for Nightmare’s head. The sun princess clasped Nightmare's cheeks tightly with her gloves, much to her confusion.

“What are you…”

Celestia then reared her head back as far as it could go, and promptly delivered a goddess-damned headbutt.

CRACK

"Oh sweet mother Faust." Twilight gasped.

Nightmare’s head rocked back violently, but was forced back into place by Celestia. Her aim was a bit off, causing them to meet head-on. Celestia had gotten the better of the two, and a stream of blood dripped from Nightmare’s forehead and down her muzzle as both mares trembled dizzily. Celestia yelled and proceeded to headbutt her again, this time adjusting her aim to smash her solid forehead into Nightmare’s tender snout.

CRACK

Nightmare reeled backwards, with her hands covering her busted maw, and she panicked when she felt warm streams of blood run down her muzzle from her nose and lips. She backed herself into a corner, trapping herself in the process. The headbutt had really did a number on her, and by the time Celestia reached her, her legs gave out and she was forced to grab onto the ropes. She tried to drag herself up, only to have Celestia’s glove smash and dig into the firm flesh of her toned stomach.

“Uurrggk!”

Nightmare winced in agony before slumping against the corner groggily. She lost her grip on the ropes, causing her to fall flat on her butt. Her back was still propped up against her ring post, so she had a good view of Celestia as she tapped her gloves together in preparation for a beatdown. Nightmare’s ears fell flat against her skull as Celestia closed the distance.

It was a tad anticlimactic when Celestia stopped, and did something else that nopony expected. Granted, a few had hoped for it, but it was still pretty shocking to watch. She turned around, and promptly launched herself ass-first against Nightmare's face.

Whump.

The crowd hooted.

"Kiss my royal flank, cunt!"

"Nnnnggghh!!!" Nightmare hissed as Celestia rubbed her bountiful ass against her face. The sun goddess shook her plot from side-to-side, taking Nightmare’s head with her as she pressed harder, occasionally sandwiching her nemesis between her ass-cheeks as she moved about. Nightmare seethed angrily under the all-encompassing greatness of Celestia's cinammony-scented butt, and there was little she could do with her gloved hands as she helplessly tried to push the weight of the sun off her.

Celestia was getting into a comfortable routine, moving her plot up, down and side-to-side with increasing fervor when she felt a sharp, stinging sensation on her rump. This was followed by a horrible stab of pain that ran all the way down her thighs.

"AHHHH!!!"

Celestia practically jumped off; tumbling forward clumsily.

She looked over to her tush to find two puncture marks right in the middle of the sun that rested on her ass-cheek. A trail of blood seeped from the two small wounds, matting the soft, golden fur around her cutie mark with a red tint.

"You bit me!" She yelled incredulously.

Nightmare grinned toothily, showing off the fresh red stains on her sharp canines. Celestia screamed in fury as she attempted to pummel her arrogant opponent once more. The fur on the back of Nightmare’s neck stood as the angry sun princess charged her. She was still backed into a corner, and worse, she was still sprawled on the mat and defenseless.

It didn’t matter.

Celestia charged with her fists at the ready, only to have the toe of Nightmare’s dark-blue boot embed itself into her cunt. The sun goddess doubled over and screeched, which was cut short when Nightmare pulled her boot back and smashed it into her face instead. Celestia was sent flying a distance backwards, and she landed near the middle of the ring with a loud thud.

“Not again….Oh, merciful mother whyyyy….” Celestia groaned on the canvas. Light from the spotlights above filled her vision, like multiple small suns in the sky.

She was beginning to get succumb to the gut-wrenching pain when lo, a great lunar eclipse blocked out much of the light. Celestia's eyes bugged out in panic.

"Oh no. No, no, no, no, nooooo-MMMMF!"

Nightmare dropped herself onto Celestia, ass first, and planted her twin moons right on top of Celestia's face in sweet, sweet vengeance. With her mouth-guard still in place, and her mouth firmly wedged between Nightmare's ass-cheeks, Celestia could only wish that she could bite her opponent. Worse, she couldn't breathe.

Celestia smacked at Nightmare's ass and hips, but from her awkward position, she could not put enough force in to actually hurt the dark goddess. She began to kick her legs wildly, occasionally managing to hit the mare on top of her. Nightmare raised her fist and brought it down straight into Celestia's stomach, eliciting a muffled groan and knocking the wind out from her chest. Her legs went limp, and her struggles began to weaken.

Shifting a bit to position herself more comfortably on her makeshift throne, Nightmare crossed her legs and signaled the announcer with a victorious smile.

"Count."

"I can't."

"WHAT?"

"You're...umm... still sitting on her."

Nightmare narrowed her eyes.

"I said count, foal!"

"Nope, no can do!"

Her own dream construct was arguing with her. A mindless drone, refusing its mistress.

That only meant one thing.

Somepony was messing with the dream. Who it was, and to what extent the dream was being manipulated, she did not know. But... it was just enough to give her asphyxiating opponent a slim chance.

That would not do. Nightmare scanned the crowd for something, anything. Nightmare scanned the crowd, and the hundreds of faces were indistinguishable from one another…except for one. Most of the ponies in the audience had risen to their feet, jumping and loudly cheering, save for one mare that remained seated. Her long, curvaceous leg was crossed over the other as she relaxed, while her head remained partly hidden under a ragged old hoodie.

Luna.

She had invited herself to the little dream Nightmare had set up, and was enjoying the show. The moon goddess winked and stuck her tongue out at Nightmare Moon. It was clear which side she was supporting.

"Such a waste, Lulu." Nightmare sneered, shifting her luscious tush from side to side. "Your precious sister is done for, anyway."

"Mmfff...! Mmfff...." Celestia's struggling began to weaken, and bruised cheeks were turning into an even darker shade of blue.

Desperately, Celestia wrapped her glove around Nightmare's starry tail that was whipping about excitedly. Her lungs were screaming in agony from the lack of air, as did her brain and the rest of her body. Her eyes began to roll up into the back of her skull, and she was losing her vision. Moments away from completely shutting down, she put the last of her reserves in a desperate, powerful tug.

Nightmare screamed bloody murder at the white-hot pain that seared into her dock. It ran up her spine, locking her in place as she fought the pain. She lurched forward, attempting to slip her tail out of Celestia's grip, only to find that it was still firmly entwined around her glove. Her momentum added to that and made the experience all the more unpleasant.

Another loud wail pierced the noise of the arena, followed by a round of angry expletives. Nightmare had finally disentangled herself from Celestia's grip, but the time she took allowed her opponent to take large gulps of precious air.

As she began to crawl away, Celestia went in for the kill. She grabbed onto Nightmare's tail again and lifted it out of the way to reveal the prize underneath: a thin, dark blue slit between her opponent's legs.

She raised her other arm, and much like swinging a bowling ball, she launched a killer uppercut into Nightmare's twat.

There was a horrific scream as the punch landed. The blow was devastating; lifting the dark goddess' lower body several inches off the ground and sending her slamming back into the canvas. Celestia then punched her again, and again, and for the hell of it, again as payback for everything Nightmare had done to her.

By the time she was done, Nightmare lay motionless on the canvas, paralyzed and gasping for air like a fish out of water. Hot tears streaked down the cheeks, pooling underneath her head as she writhed in agony.

Celesita struggled to her feet and was upright just in time for the count.

“ONE!”

“TWO!”

“THREE!”

Nightmare was still cupping her privates as she struggled to move her legs in an excruciating attempt to stand.

“FOUR!”

She used one hand to push herself up, lifting her up to her side.

“FIVE!”

“SIX!”

Nightmare grit her teeth, and forced herself to stand despite her shaking knees. She’d beaten the count, much to Celestia’s frustration. The sun princess narrowed her eyes, and opted in going straight back in to finish her off.

Celestia hit Nightmare before she could recover, smacking her with a haymaker that collided hard with her jaw, knocking her head sideways. That was the second time her sculpted lower muzzle had taken such a hard hit, leaving her with a dull, throbbing pain that left her jaw numb. Celestia was sure that another hit would send Nightmare right back down on the mat, but the dark goddess unexpectedly twisted her body and sent her elbow into Celestia's muzzle instead, impacting with a loud and nasty crack.

"AHHHHGGGH!!!!" Celestia screamed as a long stream of blood gushed from her nose.

Nightmare ducked when Celestia threw a wild, disoriented swing. From her low stance, she replied with a devastating punch below Celestia’s breasts, forcing her entire body to lurch forwards as it drove the air out of her burning lungs. Celestia was desperately trying to straighten herself when Nightmare followed up by a shocking gut punch that drove the sun princess to her knees.

Wasting no time, one glove latched onto Celestia’s mane, the other onto her tail, and then Nightmare dashed towards the corner post with all the strength she could possibly muster. Celestia was taken along for the ride, screeching all the way. When they were a few feet away, Nightmare threw Celestia into the corner with an enraged cry. Celestia hit the corner-post head first, causing the post to actually shake upon impact, which nearly knocked her out from the force alone.

"T..Twilight?" Celestia groaned as she groggily rose to her feet, gripping onto the turnbuckles tightly for support.

Twilight scrambled towards Celestia. "Princess, you're going to be fine. The round is going to end in a few more seconds an-"

"AAAAHHNNN!!!!!!!"

Celestia screamed when Nightmare's gloved fists impacted her back, striking her right in the kidneys. Her body arched in sheer agony, but Nightmare gave her little respite as she continued to pound her.

"Stop! Stop!!!" Twilight screamed.

To add to the torture, Nightmare slipped a glove under Celestia's chin and yanked back as far as she could go, forcing her back to bend painfully. Her other hand fondled Celestia's plump ass roughly, before she reared back and slammed her fist as hard as she could right into the small of Celestia's back.

Celestia's eyes widened as her mind crashed, having been hit with a blow that would have snapped her spine in two, had she been a lesser pony. Her entire body froze, and all she could hear was Twilight's horrified scream before her eyes rolled up into the back of her head.
Twilight watched Celestia slump to the ground like a ragdoll, and she was now sure that Nightmare had crippled her mentor.

"NNNOOOOOOO!!!!!!" Twilight screamed, and that was all she could remember.

She didn’t know what happened next, or what she did, but when she did finally come to her senses, she found herself standing in the ring.
Her knuckles were bruised throbbing painfully, and stood face to face with a stunned Nightmare, who was holding her bruised cheek.
Nightmare's features narrowed to a terrifying snarl.

"You dare!"

Twilight contemplated everything she had done in her twenty-or-so long years of life that led right up to that very moment. Well, it was worth it. Twilight, having incurred the insurmountable wrath of a goddess, now quaked as her life flashed before her eyes and her impending doom approached.

Twilight shut her eyes, waiting for the inevitable blow that was to come...and it did. She heard the whistle of Nightmare's glove sailing through the air, and the sound and feeling of the impact caused her eyes to open as wide dinner-plates. Her mouth opened in shock and she looked down slowly, trembling as she did. Nightmare's glove had buried itself deep into Twlight's soft belly, to the point that the knuckles were no longer visible. It was a microsecond later that her body reacted to the blow, forcing all the air to rush out of her lungs and causing her to start coughing and dry-heaving.

"Bleereggghh!!!" She half-gasped, half-cried as she doubled over in agony.

Twilight, being the bookworm she was, had never been punched like that, ever. Not even the scraps she'd been into during her many adventures had ever hurt her as much as Nightmare had. She choked back a tiny sob.

Nightmare then pulled Twilight into the center of the ring, much to her horror. She stepped back and tried to get away, but Nightmare closed the distance fast and clocked her with a jab that impacted painfully with her nose.

"Nuuow!" Twilight cried breathlessly and backed up even more.

Nightmare laughed and threw another nasty right hook that collided with Twilight's cheek, sending her entire body spinning and then sprawling against the ropes. Twilight saw stars, and tried to pull herself up a little more so she could slide through the ropes and make a run for it.

Nightmare was on her in an instant, putting her body weight on the smaller pony which prevented her from moving. Twilight had just begun to squirm in panic when Nightmare began to tug and paw at her shirt, lifting them up over her perky purple breasts and darker toned nipples. Her other glove slapped firmly against Twilight's ass and she squeezed roughly, earning her a cute little whine. "I see why Celestia likes to keep you around."

"W-what?" Twilight gasped.

"You heard me, you little piece of flank." Nightmare sneered, right before she started tugging down on the waistband of Twilight's short shorts. "You're just a juicy piece of meat just waiting to be used and tossed aside by your Princess."

"No...it's not true, the Princess would never..." Twilight shook her head vehemently as she spoke, only to be cut short when Nightmare began to bite her neck roughly, nearly drawing blood as she scraped hard. She alternated between rough licks and sensual kissing, causing Twilight to cry out. "No...please...!"

Twilight felt horrible. Her body was sending mixed signals to her brain, which was making a grave error by causing her to feel hot and aroused. She was getting increasingly desperate as she looked for a way to escape when the weight on her back was suddenly pulled away. Nightmare's eyes widened in shock as she was pulled off and turned around to face an extremely pissed off sun goddess.

"Impossibl-" She saw a flash of reddish-pink, and WHAM, a moment later she was looking up at the blinding spotlights as her head was rocked backwards from the devastating cross.

“Nopony…touches…Twilight…Sparkle!!!” Celestia roared as she launched a dizzying barrage of punches aimed straight for Nightmare’s face.

Nightmare's head snapped back multiple times from lightning-quick punches. She moved her hands upwards to protect her battered face, only for Celestia to redirect them to her unprotected body. Powerful blows continued to rock the other mare as Celestia furiously continued her blitz.

"RAAAAGGHH!!!!!" Celestia screamed again and began to pound Nightmare with even more powerful punches, who by then had rallied back and responded with a battle cry of her own. Nightmare swung back desperately, managing to slip in several nasty blows that smashed into Celestia.

Twilight scrambled to safety away from the dueling alicorns, ducking and squeaking in fear every time a wild swing from either Celestia or Nightmare nearly hit her. She looked back as she dashed towards her corner, and gasped in shock. Both mares were practically tearing into each other at this point, and there was no way one would be left standing at this point.

Contrasting gloves slammed into firm and soft flesh alike, hurting each mare dearly as they went on an offensive like never before. Celestia was running on pure rage alone, pummeling her opponent with as much force as she could possibly muster. She was putting everything she had left into her punches, but Nightmare was a stubborn opponent who just couldn't go down.

Her bloody mouthguard had been knocked loose, but she kept going, beating her opponent senseless and knocking her mouthguard out as well. The slugfest was violent and bloodthirsty as each fighter sought to overwhelm the other with devastating hate-filled punches to anywhere that could be punched.

Celestia expelled a mix of bile and saliva with a nasty lurch as Nightmare sunk her fist deep into her stomach, but she responded by launching an uppercut hit Nightmare so hard that her head snapped back with an audible crack. Nightmare sprayed out a gush of blood and spit from her mouth, along with something else that was sent flying. Her eyes had nearly rolled up into the back of her head, and her entire body keeled backwards.

"Urrrgghhh...."

That was it.

Nightmare groaned and fell flat on her back, and a formerly shiny white canine, now stained red, dropped beside her head with a little thump. She strained to get up, only to cough more blood and slam right back down onto the mat.

"ONE!" The announcer shouted, and the audience chanted with him.

"TWO!"

Celestia grinned. Nightmare had rolled onto her side weakly, and her eyes widened in horror at the sight of her sharp fang sitting in a pool of blood next to her on the mat. Her gloves reached to cover her mouth as her tongue moved to feel the area around her lost fang as angry tears streaked down her cheeks.

“THREE!”

“FOUR!”

“That’s for biting me.” Celestia taunted from above. There was a chance that Nightmare would get back up again, and Celestia would be ready to meet her with raised fists.

“FIVE!”

“SIX!”

“SEVEN!”

Nightmare growled and tried to stand up, or at least get back on her knees. She strained and moaned, but finally, with a pitiful whine, Nightmare dropped back onto the mat and weakly curled up into a fetal position on her side.

"EIGHT!"

"NINE!"

"Almost there...almost there…!” Twilight bit her lips anxiously as the countdown neared the climax.

"TEN! That's it, she's out!"

"Yeeeessss!!!!! Yeeesssss!!!!" Twilight squealed, hopping up and down on the ring apron.

Celestia breathed a sigh of intense relief. Her head was pounding, and her heart was beating so fast she was sure she would collapse. There was one last thing left, and as much as she wanted to crawl back to her corner and into Twilight's embrace, she felt that it had to be done.

She took one more deep breath, and with a winning smile, she raised both arms high into the air in triumph. The crowd erupted into applause and cheers, lovingly showering the spectacular sun princess with applause for her hard-earned victory.

Celestia was so caught up in the fanfare that she never noticed the battered and bleeding Nightmare that was on the ground, down, but not out for the count. The dark goddess had pulled off her gloves discreetly, and was slowly making her way towards the sun princess from behind. Celestia was just about to start bouncing to drive the crowd even wilder when Twilight screamed loudly.

"Princess, behind you!"

Princess Celestia hadn’t even turned her head to see what was going on when she felt something enter her sopping twat.

“Oh buck.” She whimpered.

Nightmare plunged her manicured fingers as deep as equinely possible into Celestia's unguarded marehood. The sun princess' breath hitched violently at the sudden intrusion, and her entire body froze. With Nightmare's fingers so deep inside her, Celestia was at the mercy of the dark goddess. There were many things; nasty, nasty things that went through Celestia's mind, the foremost being a tiny sense of pleading hope that Nightmare wouldn't start clawing her.

Nightmare slid her slick fingers out ever so slightly, moving them about as she did to teasingly massage the inner walls for a moment, before proceeding to plunge them in again with twice the speed and force.

"Nggaaaah!!!" Celestia exhaled with a loud moan as pleasure rocked her body. She went up onto her tip-toes as ecstasy coursed through her mind.

Then Nightmare pulled out once more, slammed into Celestia, then pulled out again, rinsing and repeating to settle with a furious thrusting motion. Celestia’s howled and mewled, then her legs buckled, sending her onto all fours as Nightmare continued to ram her fingers into her like a piston. She began to crawl away in panic, only to have Nightmare grab her tail and drag her back painfully to be finger-fucked into oblivion.

Nightmare plunged her fingers in and out of Celestia's increasingly drenched pussy, relishing in the wet shlicking noise and Celestia's moaning. Celestia's body was becoming more and more responsive to Nightmare, causing her inner walls to constrict and try to squeeze at Nightmare's fingers, making the passage all the more tighter and sensitive.

"No...no...nhhhh...!" She groaned, shutting her eyes as tightly as she could.

"You like that, sunslut? Hmm?" Nightmare mocked from behind.

With an angry growl, Celestia lifted her leg and kicked as hard as she could. The sole of her boot collided with Nightmare's face, sending her flying backwards and allowing Celestia to drag herself away. The fighting had become wild and, at extreme close-quarters, Celestia found herself without the swinging space to properly land her punches. In anticipation for grappling, she began to desperately paw at her gloves, trying to remove them.

"Use your teeth, Princess!" Twilight screamed from the corner.

Celestia bit down into the laces, tugging and pulling like a wild animal until they came loose.

"Yes!" Celestia squealed, tugging her glove off and using her now freed hand to undo the other to toss aside as well.

Nightmare was down, having taken the blow hard, but with a primal scream of rage she forced herself back up, burning with determination to finish Celestia once and for all. As she rose up to her knees, she only had a half-second to react when Celestia turned around and slammed into her with her entire body, sending both mares tumbling back onto the canvas.

They wrestled around, grunting and straining their weary bodies against each other before Celestia finally managed to lift herself upright on her knees. With one hand, she grabbed onto Nightmare's starry mane roughly and pulled her up to meet her. The dark mare responded in kind, reaching around and grabbing a handful of Celestia's rainbow-hued hair.

Both mares were face to face, breasts pressed tightly against each other as they gasped for air. Their eyes bore hatefully into each other as they breathed hard, waiting for the other mare to make her move. It was then Celestia jammed her fingers up her knuckles into Nightmare's wet marehood, causing her to gasp at the violation. She pushed hard and deep before curling them inside Nightmare and waggling a bit in a challenging manner. Nightmare half-moaned, half-growled and responded in kind, shoving her own fingers into Celestia.

Twilight’s jaw dropped.

There was a dead silence in the arena for a tense few second, and then, as if on cue, both mares began to furiously thrust into each other with everything they had. They clung onto one another for support as their legs went weak, viciously latching onto their manes to prevent the other from escaping.

Locked in a hateful embrace, both mares were frantically thrusting their fingers into one another, moaning and whimpering despite trying not to. The feeling was absolutely maddening to each mare; both loathing the fact that she was being violently pleasured by her most hated foe.

Nightmare slipped more fingers between Celestia's folds, adding to the intense pleasure that was flooding her body, and Celestia was hard pressed to respond as her moans became even higher in pitch and volume. The sun princess used her free thumb to begin pressing and flicking at Nightmare’s throbbing clit, earning her a long, sultry moan her opponent.

The once ravenous crowd had remained silent; mesmerized by the different kind of fight that was taking place in the ring. The loud shlicking noise of fingers pulsing in and out of wet pussy, along with the increasingly loud cries of both mares were the only sounds of in the arena.

It started off as a soft drip-drip-drip; the soft pitter-patter of droplets of her sweet nectar onto the canvas. Nightmare bit her bottom lip, but her jaw eventually loosened to the point that her tongue lolled out of her mouth, leaving trails of messy drool down the sides of the chin.

"Nhhh......." She was whimpering loudly, her pitch high and feminine.

Celestia was spurred on by her opponent's horny moaning, and she began to groan in time to Nightmare's pulsing fingers. She was faring no better, and a fiery welling in her nethers warned her of an impending orgasm. Celestia’s eyelids began to flutter, as did Nightmare’s, and the aroused screams of the alicorns had reached a frightening crescendo as the climax of the entire ordeal neared.

Nightmare Moon stopped fingering Celestia …and then the arena was graced with the sound of Nightmare's screaming as she came. The dam had burst; and a furious torrent of mare-cum flooded the mat below in a series of squirts and wet, wet spillage. She had finally reached her breaking point, arching her back and throwing her head backwards to release a loud, primal scream.

"AHHHHHHNNNNNNN!!!!!"

Her back arched backwards and her body trashed violently in Celestia's unloving embrace, who prolonged her orgasm by continuing to furiously thrust her fingers into the squirting mess below.

"Ahh, ahhhhh, ahhh.....!" Nightmare continued to let out a series of particularly high-pitched moans; body spasming in time with the contraction of her inner walls and the thrusting of Celestia's fingers.

There was a thick, nectarous pool of female cum beneath Nightmare by the time her body gave out and finally slumped against a triumphant Celestia. Her own weak fingers slid out of Celestia's still-throbbing pussy, and her arm drooped limply to her side as her entire body went limp. With a quiet moan, Nightmare Moon mewled softly like a lover basking in the afterglow of sex.

Celestia nonchalantly shoved her off, causing her to fall flat on her back.

"Well then,” she hummed, rising to her feet and approaching the downed fighter. The crowd had begun to chant Celestia’s name as she took her time to lick and suck each of her fingers that were covered in a slick layer of Nightmare’s wetness.

"Neigh, neigh, no more…" Nightmare moaned under Celestia’s shadow as she towered above. "P..Please!"

Celestia ignored the pleading and knelt, straddling her arch-nemesis to promptly shove her bruised, glistening pussy right in her face. Nightmare blanched and shook her head in panic, moving her head to avoid the inevitable.

"I'm not leaving this stupid dream without compensation for all the crap you've put me through!" Celestia hissed. "Lick!"

Exhausted, Nightmare shut her eyes in shame and stuck her tongue out to lap at Celestia's folds. The taste of salt and a tangy sweetness hit her refined tastebuds, and it reminded her distressingly of vanilla; how she hated that.

"Tia! Tia! Tia!" The crowd yelled even louder. Nightmare contemplated biting the solar bitch, but that would have likely prompted another beatdown she was in no position to take.

"Faster. Harder." Celestia moaned loudly. She tightened her grip on Nightmare's starry mane and began to tug violently.

Nightmare complied, making longer strokes and pressing her tongue as far as it could possibly go within Celestia’s folds, lapping at the silky inner walls, desperately trying to finish Celestia off before she died from sheer humiliation. She had taken her fair share of mares before, and she went straight for Celestia's bruised clit. She kissed Celestia's love button, forming a tight seal with her lips. As she suckled, her tongue lashed harshly against the perky nub, prompting short, sharp gasps of pleasure from Celestia.

"Ahhnn, yes..! Buck, that's goood..."

A sly grin formed on Celestia’s face, and she spat on Nightmare's horn, causing the dark mare to wince at the wet, slick feeling of saliva trailing down her long, spiraled horn.

"You're a disgusting whorse." Nightmare paused her licking to grunt angrily from below.

"Says the mare licking my slit." Celestia sneered in response and began bucking her hips again to get Nightmare back to work. She mumbled something in response that was muffled by Celestia's snatch, and the vibrations only served to make the experience more pleasant for the sun goddess.

"Now, I think you deserve a reward, slut." Celestia cooed as she continued to hump Nightmare’s snout.

Nightmare only grunted, and from the sound of it, she was getting quite pissed.

"Oh no, no need to thank me, my dear." Celestia bucked her hips again, purring in approval. "It's just in my benevolent, generous nature to reward those beneath me."

By then, Nightmare was seriously contemplating tearing into Celestia's puffy vaginal lips with her remaining canine when she felt a rush of pleasure paralyze her.

"Mmmmmpphhh!!!!" Her eyes shot open and her attention was ripped away from the warm slit in front of her. She rolled her eyes up to see what in Tartarus was going on; and she gaped at the sight of Celestia’s hand tightly wrapped around her horn.

The lengthy, impressive spire of obsidian was then treated to a hornjob from the sun goddess, causing Nightmare to squeal and her hips to buck upwards. Celestia’s hand moved up and down the long spire in a slow, sensual pace, from the very tip right down to the base where it met her forehead, causing Nightmare’s head to bob in time to the motion.

Shlick. Shlick. Shlick.

She squirmed under Celestia’s weight, causing her muzzle to rub even deeper into Celestia’s pussy, much to the Princess’ delight. She picked up the pace and really clopped the horn hard, furiously sliding her hand up and down in a way that would have caused any stallion to explode. Nightmare was plunged deeper and deeper into intoxicating lust, and her eyelids were fluttering in sheer pleasure from the royal treatment.

Celestia's battered body finally shivered, and with unbridled pleasure, a loud and delirious scream, and a proud display of her glorious wings, she came, hard. Her orgasm sent juices gushing between her thighs like a fountain, forcing Nightmare to either start swallowing her nectar or to drown in it.

Being the compassionate mare that she was, she continued to jack her opponent off, prompting Nightmare's own horngasm. Brightly colored liquid magic exploded from the tip of her horn like boiling water and steam from geyser, hitting Celestia in the face and breasts and coating her alabaster fur in a layer of sparkling blue goop. A loud scream erupted from Nightmare's throat, but she was met with another gush of Celestia’s cum that choked her.

Wave after wave of paralyzing pleasure hit Celestia, practically soaking the mare beneath her, but at last, her orgasmic high ended. Celestia groaned, and tumbled sideways off Nightmare. With a dreamy smile, she lay flat on her back, body twitching and legs spread wide open as she stared up at the bright spotlights on the arena ceiling. All she could hear now was the wild cheers and delighted screams, and Nightmare coughing and hacking Celestia’s salty-sweet arousal from her lungs.

"Whorse...." She heard Nightmare weakly groan, "This isn't over..."

It was finished. Celestia shut her eyes and waited to awaken from the dream. She could already see the sun rising in her mind, and smell and taste the fresh dew of the morning. She waited...and waited....and waited...

Nothing.

The crowd was still cheering, but all Celestia could really hear was the heavy breathing of Nightmare and herself.

There was one last thing to do, then.

Weakly, she struggled to rise to all fours, and began her slow crawl towards the fallen goddess.

She straddled her, but Nightmare offered little resistance.

"Time to end this once and for all." Celestia said grimly, preparing to finish off her opponent once and for all. The crowd began to hush, and Twilight was practically shaking in fear of what Celestia would do.

Nightmare snarled weakly. "...Go ahead and try, bitch."

"But before that!" Celesitia dropped her cold façade and grinned cheekily "Who's the best mare?"

Nightmare gaped, before she growled angrily. "Kiss my flank, whorse!"

There was a horrible crack, followed by a burst of intense pain as Celestia smashed her fist into the side of Nightmare’s muzzle.

"Nnnnggghhh!!!!"

Nightmare’s eyes widened in shock, and a trail of blood spewed out from between her lips.

"Wrong answer," Celestia replied as she grabbed a thick handful of Nightmare's starry mane. "I'm going to ask you again."

"WHO'S THE BEST MARE?!"

"Fuck y-"

CRACK

"Still wrong."

This time, she was sure she had dislodged a few teeth. Nightmare screamed, feeling her jaw nearly snap from the force of the blow.
Celestia leaned in very, very closely and hissed in a dangerous, threatening tone she reserved specially for stubborn dignitaries.

"...Who?"

Nightmare tried to speak, only to choke and spit out a mix of blood and another tooth as she coughed violently. She choked back a quiet sob, and shut her eyes tightly.

Celestia waited patiently, and finally, in a tiny voice, a teary-eyed Nightmare answered.

"...You are..."

"Louder."

"Y..You are!!!"

"LOUDER!"

"YOU ARE!!!!!!" Nightmare screamed to the heavens, and the world seemed to acknowledge her cries as the ponies in the crowd yelled their agreement.

"Yes, yes I am." Celestia huffed in satisfaction before cocking her fist back one last time. "Don't you ever forget that."

WHAM

Celestia's knuckles hit her square in the face, and that was it. Nightmare gurgled, and her eyes rolled up into the back of her head. Her entire body shuddered under Celestia for a moment, before going limp as she was finally knocked unconscious.

"Fucking finally." She groaned, and immediately, the dream world began to shift. With a smile, she let herself rest, and her eyelids grew heavy. Celestia let out an intense sigh of relief, and her entire body slumped over backwards with a thud.

The dream began to wear itself down, and the world around her rippled like the surface of disturbed water. The lights of the arena dimmed, and the loud chanting in the crowd softened to a dull thumping noise in the background, gradually decreasing in volume until everything was replaced with silence and darkness.

Celestia's smug grin only widened as exhaustion finally took her and the last thing she saw was the runic circle on the ceiling glow brightly for a moment before shattering into a million pieces.

Phew. ("-_-)

Epilogue

--- Epilogue ---

Princess Celestia opened her eyes groggily to find her entire body covered in a sheen of sweat. Her muscles strained and ached as she tried to sit up on the wet bed-sheets that were soaked with arousal to the point that it was beyond salvaging. However, and quite importantly, she was awake. She blinked the sleep away, pinching herself as well just to make sure, and charged her horn. The darkness in her room was blasted away by an intense golden glow, and Celestia laid her head back onto her pillow with a contented sigh as the first rays of the morning sun entered her room through the glass balcony doors.

The dream crumbled away just as Princess Luna stepped out of the arena and into the starlit landscape outside. Purple skies were framed by dark blue constellations and silvery nebulous systems of crisscrossing pathways that let Luna walk the world of dreams. She shut the door of the building with a loud slam, and was about to demolish the cursed thing with her magic when she decided she was just too tired to deal with it at the moment. With a loud and exhausted sigh, she sat on the grassy field below and lay down lazily. Never mind the clean-up process, the crisis had been averted, and all was well and good again. She had her cake-hogging sister back, and she congratulated herself on a job well done.

Nightmare Moon retreated to a relatively obscure part of the Dreamscape, tending to her bruises. A spell or two had fixed most of everything, save her wounded pride. Hatred welled up within her chest, and she smashed a solid hardwood table clean in half with a clenched fist.

"CURSES!" She screamed, unheard by anypony.

In the privacy of her chambers; which she had practically torn apart, she vented her frustrations. The room, illuminated by moonlight and the soft glow of crystals, served as refuge from pesky dreamwalkers that scouted the void between dreams on behalf of Princess Luna.

Granted, she would have built a giant, imposing castle of doom (and screwed with everypony's dreams) as any good villainess should, but she was lacking a tad bit on magical powers. The bout itself had taken much of her reserves, and her simple room would have to suffice while she bided until it was time to strike…again.

Twilight Sparkle found herself in complete darkness just as the doors to the arena slammed shut and the last pony stepped out.

“…Hello?”

Her voice reverberated around the empty building, and a chill ran down her spine when it echoed spookily.

She whined.

“Aww buck.”

The End
