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 or flight.

Fight or flight.

Fight.

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.
