Her sister was gone. And had been for quite some time. It had hurt Celestia to do that to her, send her away for so long. But she’d had no choice. Still, what little parts of Luna were still, well, Luna, were there. And she tried to find time to visit her sister, in her dreams, since she couldn’t go up to the moon on her own.

Royal Alicorns had the best traits of all types of ponies. The strength of the earth pony, the flight of the pegasus, and the magic of the unicorn. There was one other thing that they had, as well. All of the royal alicorns were herms, as well, with long, thick cocks, and tight, muscled cunts, both as strong as any normal pony’s. It made sexual battles like this one a sight to behold. In the past, in fact, they had been a sight to behold. The citizens of Equestria loved to get the chance to see their royal princesses in battle. But for almost a thousand years, it could only happen here, in Luna’s dreamscape.

For years, it had been all sorts of places. Cities, fields, anywhere Luna could think of. But tonight they stood on the dusty surface of the moon, as they had for over a century, every time Celestia had been able to visit. It was all that Luna knew, now. Or at least all that she cared for. Or perhaps just a way of pulling a joke on her. Very old creatures could hatch very old schemes, and a scheme to kinda tease her sister about living on the moon by making her think it was all she could think of was right up Luna’s playfully-cruel alley.

On Luna’s mental moon, there was air. And while it was cold, it wasn’t so cold that Tia was freezing. It was just chilly enough that her big nipples perked up stiff in the air. There was some light wind, blowing across a should-be-bare lunar plane, the shifting currents choosing to vortex right beneath her spread legs. She looked around her, waiting for her sister to make an entrance. Usually she showed up by now.

The vortex of air swirled faster between her legs, no longer merely eddies of gusting wind, now going from mildly tickling to actually quite arousing. And as the wind blew faster, from arousing, to quite intense. She let out a low groan as the swirling winds managed to spread her cunt and... In a second, a thick, hard cock was filling her! Dark hands grasped her round breasts, and she felt herself being squeezed against her sister’s body. Unusually, her breasts pressed up against Celestia’s shoulderblades. She looked down, and saw the hands on her breasts were a pitch black, and as her foe rolled her hips, that huge shaft dug all the way into her, large and powerful enough that it she felt as if her ab muscles were being spread apart by the size of the cock on her foe’s body. She groaned out, and felt her body being lifted from the force of the other alicorn’s thrust. She was being fucked, but not merely by Luna, but by the beast of a woman known as Nightmare Moon.

“Hello, ‘Sister~’” The monstrous woman mocked, “It’s been a while. Sorry Luna couldn’t come out to play.”

Celestia gasped, squeezing down on that cock as hard as she could. But she hadn’t expected it, hadn’t prepared, and so, the force she could exercise was limited. Instead, she reached up, to grab the back of the neck of her sister’s alter-ego. She gave her a small kiss. “I’m glad to hear it love... Because I’d hate for Luna to feel the beating you’re about to get!” She raised a heel into the other woman’s cunt. Her legs were strong - Her whole body was strong, she looked as much like a muscled bodybuilder as she did a caring princess, with bulging muscles coating every inch of her beautiful form. And her kick struck true, the other woman gasped out. And so she raised the other foot, and stomped on Nightmare Moon’s. She finished the assault by tossing her head back to headbutt her sister. Nightmare Moon stumbled away, and Celestia turned, her hand shooting out to wrap around the giant cock.

Luna was shorter than her sister. Nighmare Moon was taller, her muscles slightly smaller, but every bit as bulging and powerful as Celestia’s. She squeezed down on a cock the size of a can of cider, the muscles of her forearms bulging and shuddering, and she enjoyed the pain on Nightmare Moon’s face. Even if it was Luna playing games with her, Luna knew well not to take this body unless she wanted a true beatdown that would make other ponies squirm in fear of their princess. She jerked that cock, jerking a few drops of pre out roughly, then slapped her sister, turning her head and making her grunt out in pain.

Nightmare moon slapped her right back. The force of the blow sent her staggering, only stopped from going too far when a powerful hand gripped her cock, starting to jerk her right back. Both women tried to crush the other’s cock, as their hands slid across each-other’s throbbing shafts. Celestia could feel she was gaining some ground, her foe’s cock getting slick, when she was assaulted again. This time, by an obsidian fist smashing into her. She felt the huge muscles of her abs shrink from the assault, and coughed in pain. Another one, now into her neck, left her gasping for air and resting against her muscular sister’s body, too tired and out of breath to keep at it, forcing her to allow her sister free reign over her shaft. Nightmare Moon’s agile, equine lips pressed to her neck, starting to suckle at it in addition to the jerking, and Celestia groaned. Her arousal was growing, she would need to get herself under control if she was going to win this. Her sister’s hand continued rocketing up her arousal, her breath came heavier against Nightmare Moon’s chest. She had to pull away if she wanted to last, she had to regroup, and come out strong after her sister’s dark side. Pre flecked from the tip of her cock with each rough pull on the bulging shaft, establishing the younger but larger sister as the more powerful, as flex of fluid splashed on Nightmare Moon’s thighs.

She needed to escape, before more than pre was falling on her sister’s long and lovely legs. She jerked back, only to be stopped with a firm hand cupping her tightly muscled ass. She was slammed back to her sister’s body, and now they were melded together. Nightmare Moon continued working over the princess’s cum-filled cock. With the two of them this close together, Tia’s shaft was pressed up to Moony’s muscled abs. Cruel draconic eyes stared into hers, and Celestia knew that, at least for now, she was trapped against the black bodied, marked only by the moon on her flank, and, quickly, starlike flecks of pre on her stomach. Celestia’s primary task right now was to stop the stars from becoming a nebula splashed across her. Still not near orgasm, but needing to be concerned of that strength. Whatever she did, she would need to make sure it was quick and hard. Her arousal was growing dangerously fast. Their breasts mushroomed together as the dominant mare worked her over, making the royal cock her plaything. She gritted her teeth to try to outlast the pleasure that Nightmare Moon pumped into her. Her cock twitched against the other alicorn’s abs. Moony sneered, and Celestia groaned. The other alicorn seemed to be thinking of something, and Tia knew it would be nothing pleasant for her. Her sister’s dark side loved to do more than just beat the good alicorn, she wanted her humiliated. And if Moony was here, even in a dream, Celestia was in danger of a mentally shattering defeat, if not a deadly one. She had to escape.

She tried to strike, but Moony struck first. The hand on her cock dropped, only to smash her abs before she could savor the safety. She fell on the monster again, and felt those massive arms wrap around her back. In an instant, she was hiked up, her cock pressed to the black abdominal muscles, arms around her back. Her sister rolled her waist and hips like a belly dancer, and Tia’s cock rubbed on the dancing muscles. The hot rocks of her abs were an arousing and slightly frightening display. There was just enough give that they didn’t bleed, and the hard muscles had just enough covering from her sleek black coat to keep this arousing, not grating. Her shaft reached nearly to those round, black breasts.

“Mmm, enjoying, sister?” She asked, but a quick squeeze to drive the air out of Tia’s body prevented the white mare from answering, only able to give a groan of pain as the breath left her. Nightmare Moon laughed, lifted her up, and slammed her down... Still in the crushing bearhug, Nightmare Moon slammed Celestia down on her bulging cock! The ivory princess cried out as that cock dug deep in her cunt again, her muscles spreading around the rock-hard shaft. Her eyes rolled back and she gasped as she was filled up with that giant cock. She summoned all the strength that she could, hoping that it would be enough to at least slow her defeat, and SQUEEZED down with her hot core muscles.

It wasn’t enough. It was like trying to grasp onto a rock with a slippery glove. She felt the muscles in her sister’s arms slide up her back higher, to get maximum leverage, and then Nightmare Moon showed her what a squeeze could really feel like. She was pressed up to a body carved out of pure volcanic stone. The muscles in the arms squishing the life out of the sun princess were digging diamond-shaped imprints into her back, a fitting shape, considering how hard they were, crushing anything that stood in their way. Her ribs compressed in Nightmare Moon’s cruel grasp, a tiny fraction of an inch more and they’d snap. Celestia tried to fight back, by spreading her white wings against the black pillars crushing her, but there was no way to move. There was no way to fight that kind of strength. Nor was there any way for her to fight the cock that was buried so deep in her it felt like it might come out her throat. Nightmare Moon began a quick, rough rhythm of lifting and dropping, taking Celestia into the air, and dropping her down to the hilt of her shaft. Her cunt scrambled to grip at the cock, but only found its muscles easily overridden. Once more, she felt the compression beginning, threatening to take her ribs out, now. It might not carry over into the waking world, though one could be surprised what the body will do to emulate its dreams. That wouldn’t matter, though, because the threat of a beating at the hands of nightmare moon was just as scary as its after-effects. Desperate to save herself from being squeezed into paste, she flexed her wing muscles harder. She had to save her ribs from being shattered in that grasp. White wings fought black arms to protect the princess’s body.

Inevitably, the arms won. She was strong, but she didn’t have a fraction of the leverage or muscle-power necessary to fight Nightmare Moon like this. It had been a last hope for protection, and it had only made things worse. Now not only were her ribs broken, but her wings as well, cut into by the mechanical vice of her own sister’s arms. She coughed once more, blood dripping from her mouth, a result of the internal damage her sister forced on her with her sadistic squeezing. Nightmare Moon’s shaft continued to dig into her, and despite all her efforts, her pussy was responding, dripping sexual juices as her sister resumed the task of bouncing her, lifting her, and dropping her down to the hilt of that cock. These lifts and drops were even harder on the poor princess, for now, each one of them forced her to suffer the torment of her shattered wings being ground to dust in Nightmare Moon’s arms, of her ribs being pounded once more despite having already ceased to fight the force being inflicted on them. She considered herself a mare of honor. In fights with normal ponies, even unicorns, she would never dream of using her magical powers. A body-to-body contest was only worthy as long as only bodies were doing the contesting. Others could fight magical duels. Now, though, Celestia had no choice, if she wanted to avoid her body breaking down. She only hoped that Luna had been kind enough to allow her to still draw sun from sunlight reflecting off the moon. Staring into the sun, the only pony capable of doing so without risking blindness, Celestia focused on drawing its power. Her horn began to glow.

She closed her eyes, taking in the power of the sun. Trying to focus only on that, to draw as much of the energy as she could. The warmth filled her body, driving out and calming the pain that her sister had inflicted. She was so focused on this, that she didn’t even notice the hand gripping onto her horn until it was almost too late. But notice she did, as Nightmare Moon’s black hand gripped her horn, and twisted. She forced out all the power into Nightmare Moon, making her sister gasp out in a mix of pain and pleasure. Magic didn’t much care if you were a masochist. If a spell said that it felt like pleasurable fire, it did. And she knew that Moony right now felt like she’d slammed her fist into an inferno of ecstasy. Nightmare Moon’s hand shot away from her horn, and a second later, Celestia felt herself dropped in a heap of snow-white muscle on the ground. She looked up at her target, the blue inner muscles of Nightmare Moon’s hot, dark cunt. They were both massive bitches, powerful women who the average stallion would run and hide from if he knew they were coming after him. That is, if he didn’t cum himself thinking of the hot, dark hole that Celestia was looking up at.

Celestia didn’t have much choice. She wasn’t going to be able to sit this one out, to try to wait for a better chance. Nightmare Moon was in erotic pain from her horn burning her hand, and Celestia had to capitalize. She thrust forward, sheathing her horn in the dripping blue cunt of her dark sister. Nightmare Moon gasped in pleasure, Celestia did the same. The horn of an alicorn was an incredibly erotic thing, it felt like the perfect dildo if you wanted it to. When doing magic, it warmed and vibrated. But it was every bit as sensitive as a thick cock, if not more so. And those inner muscles were built to milk cocks.

Celestia was in no place to appreciate that fact, though. She had more important things to think about. Like winning this match against her wicked bitch of a sister. She concentrated, as she had before, and sent another pure blast of magic right up into Luna’s pussy. It felt incredible for both of them, but judging by the “Gayayyayyaaaaaaa!” coming from above her, Luna clearly was getting the worse of it. She pulled back, and thrust again, and blasted the magic once more. Drops of pre-cum fell on her back and her neck. She reared her head back, focused, and blasted a third time. Obsidian muscles spasmed in pleasure over her, and feminine juices flooded over her head and back. She had Nightmare Moon on the run, here. Or at least, she had her struggling. She couldn’t see the look on her face from down here, she could only look at her carved calves, and the way the muscles twitched. She had to hope that was enough, and pulled back.

Nightmare Moon fell to her back, Celestia’s pleasure had done even better than she hoped. Her pussy may not have been spasming with cum, but it was spasming nonetheless, its owner groaning like a wounded animal. Tia looked up at her, on her hands and knees, panting. Fortunately, at least now, her sister was as tired as she was, or close to it. Both big, beautiful bodies, one snow-white and one coal-black, heaved as the pair of princesses recovered from that last attack. Celestia managed to get back first, and lunged forward, burying her muzzle between those gorgeous thighs, and lapping at it. Her broad equine tongue rolled up against Nightmare Moon’s clenching cunt, tasting the slick juices that slipped from her inner muscles. The blue walls tasted no different than any other mare’s, but the inner muscles that Nightmare Moon possessed made the experience more like that of licking a rock after a rainstorm, than pleasuring a princess. She sealed around the other royal cunt with her agile lips, and started to suckle like she would a cock. She pulled at her cunt, suckling the flesh into her mouth. Nightmare Moon arched her back, and cried out in ecstasy. Celestia had had many years to learn every inch of a mare’s body, and the millenia-old-mare gave no quarter to her equally old, but less experienced, opponent. The flesh of Moony’s folds pressed to Tia’s mouth, her outer lips dripping, it was less like the normal act of cunnilingus, and more like making out with a woman who had just finished the act. The juices drooled into Celestia’s mouth, and she lapped more, licking out what she could. She looked up from between her legs, looking up over the landscape of her muscled body, to try to get a handle on how horny she’d made Nightmare through her lapping. How much strength was still left in that body.

Despite the rolling of hips and the heaving of her chest in pleasure, Nightmare Moon was looking down at her with a confident, if lust-drenched smile. Their eyes locked, and in an instant, Celestia was wrapped up between those tree-trunk like thighs. The striations of nightmare moon’s calf dug into the back of her neck, forcing her muzzle deeper into the wet pussy of the dark princess. She gasped, releasing Moony’s flesh, and a second after, she felt Nightmare Moon’s inner hole clench in on her. The muscles lining her walls pulled her tongue deeper into the dark blue pussy of the midnight mare. She tried to pull her head back, but Moony’s calf was an iron restraint, forcing her to just lie there and take it, as her head was squeezed up close. Cunnilingus with another horny mare was erotically dangerous, the scent of her pussy could drive any cock wild, and Celestia’s was no exception as it pressed on the dark moonrock. She squirmed, but there was no release, and no respite. She could barely breathe, and the little she could only filled her lungs with the juices, making her shaft dampen the fine moon dust with alicorn pre. She sealed her lips, and began to suckle again, trying to pull the flesh of nightmare moon’s pussy into her mouth so she could once again chew down on it, but those muscled walls were flexing and milking her tongue as if it was a stallion’s aching cock, and it was her duty to relieve it of its creamy tension.

The sensation was overwhelming. Even her tongue was being fucked. Unconsciously, she began to grind her cock up against the dust of the moon. To her shock, her cock was soon enveloped by a hot, dripping hole. Every bit as hot and powerful as the cunt squeezing on her cock. She looked up at Nightmare Moon, who just laughed at the poor alicorn princess, who was now stuck fucking the moon with her dripping cock, as a magically created cunt suckled on her creamy shaft.

“What’s the matter, sister?” Nightmare Moon taunted her, “Did you forget that I have the power here? If I want your cock to squirt out, it will. You’re powerless to stop that, and if you think a magical blast can change it, you’re as stupid as you are weak. I’m the mistress of dreams, bitch, if I want you to get fucked by the moon, you’re getting fucked by the moon.” She laughed, and wrenched her hips.

Celestia screamed in pain, agony shooting through her body starting at her neck. Her muscles turned against her will, manipulated by the massive mare clenching her between muscled thighs. The created cunt suckling on her shaft did nothing to make things easier, wetly suckling on an aroused cock, Celestia could barely contain herself. She was struggling just to keep from seeding the moon, but worse, the clenching cunt kept her from rolling with the attacks, and as those powerful hips twisted once again, Celestia cried out, her neck muscles on the verge of tearing at their mistreatment by Moony’s powerful thighs.

Finally, desperately, she bit down on the flesh trapped in her mouth. The musclemare cried out in erotic torment, as she chewed on the powerful flesh. Blood seeped from her injured pussy, and the lunar fuckhole surrounding her cock spasmed like it was cumming for her. Celestia could see that the two were related, raised her hips, and thrust. Her cock pumped into the moon, and juices splashed on her muzzle. She chewed and thrust, being given two different cunts to work with, and her dark bitch of an opponent was reeling from her two-pronged assault. Finally, the legs around her head unwrapped, and Nightmare Moon tried to slip away. She kept her cunt clenched between her teeth as long as she could, before releasing the bloody, battered hole from her grasp. Nightmare Moon backed off, and Celestia ground herself on the cunt her foe had created in the moon, allowing it to pleasure her, payment for her continuing to pleasure her wicked sister, before extracting herself from its lustful grasp. Finally, sweat dripping from both their bodies, juices drooling from hungry cunts, pre falling from powerful cocks, the two mares faced each-other. Celestia hoped she looked stronger than she truly was, for all she had struck back, she still suffered from broken bones and battered muscles, while her sadistic enemy stared her down. Not all the blood dripping from Celestia’s lips came from Nightmare Moon’s torn pussy. This game was as much mental as it was physical. She feigned confidence, raising her hands above her head, as much as it burned her aching body to do so, she pressed them on the back of her head.

“You think I’m scared of you, sister?” She asked, and looked between her legs. “Go on. Suck my cock. I won’t stop you.”

Nightmare Moon watched her suspiciously, but after a few seconds, gave a confident smile, approaching, and looking Celestia in the eye. The pitch-black princess approached slowly, and the two fuckwarriors stared each-other down. Nightmare Moon was bigger, stronger, taller, and looked in perfect shape, while Celestia’s white flesh was marred by purple bruises. Moony watched for any hint of fear, but there was none from the white alicorn. Celestia was unsure, certainly. But she knew this was it, and dared the black mare to do her worst. Finally, Nightmare moon sank to her knees.

Celestia kept her face as passionless as a statue, as Nightmare Moon dragged her longue tongue up her thick cock. Despite her best efforts, a glob of pre formed at the tip. The dark mare sealed her lips around it, and sucked. Tia gasped at the teasing of her sensitive tip. Nightmare Moon laughed. Gritting her teeth, Celestia grabbed the pitch-black mare by the back of the head, and slammed forward, forcing her foe to deep-throat her before she was ready.

Nightmare Moon gasped and gagged as Tia rammed her cock into her full throat. Juices fell from Moony’s mouth as she tried to expel the unwanted invader, but Celestia held her firm, choking her foe on her thick bitchbreaker. She coughed and spluttered, saliva falling wildly from her mouth. Tia held firm, it was working. She was choking the black mare on her cock, choking the musclebound bitch. Cum churned in her balls, eager to spurt down the cruel bitch’s throat, but she gritted her teeth and held on as black hands pushed weakly on snow-white thighs.

“Ohh... Oh god, yes, choke on it” she panted, the pleasure partially overtaking her, but only partially. She pounded Nightmare Moon’s muzzle with her hips, humping the midnight mare as she struggled to keep her own orgasm in check. The splutters and spasms of her sister’s tight, wet throat around her cock, the humiliation of the larger woman looking up at her as she was forced to choke on a gargantuan shaft, didn’t make that easy. Red-hot lightning strikes of pain shot through her tormented body, as broken bones ground together from the struggles to keep the wicked mare under control. It was all she could do not to scream in pain, but there was time left. She needed to not just make Moony choke, she needed to make her break. Her opponent’s pulls, attempts to slip away from the thick royal shaft, grew faster and harder, as Celestia cut off her air with her cock.

Soon, the desperate pulls of trying to get off, grew weaker. More rapid, but less strong. Quicker, but unscientific, as the lack of air got to the wicked woman’s head. Celestia finally let her off, letting the dark-coated mare pull away, and fall to her hands and knees, drooling both pre and her own saliva after Celestia’s assault of her mouth. It had been hard not to just give up and cum right there, that gagging, dripping mouth was a tempting place to unload a lot of seed. Moony’s chest heaved as she spluttered, and Celestia fell on her, almost literally. Her muscled arms wrapped around the thick, powerful torso of the wicked woman, her black head near Celestia’s hip. She gave a single, vicious squeeze and lift to Nightmare Moon’s dark midsection, driving any air still remaining from her lungs, then reached down to grip that hard cock, and jerk it. It was as stiff a pillar as her own, her fighting back had been effective, though the splintered bones of her back and body attested still to her sister’s earlier brutality. But Moony’s pre-dripping cock had just as much falling from its tip as her own did. The battle, as difficult as it was, was within reach. She needed to keep herself under control, keep her orgasm from staining her opponent, and Nightmare Moon had to do the same. It was, despite the early assault, a dead heat, as Celestia roughly jerked the full length of the wicked mare’s shaft.

They had fought long and hard, and for both overworked mares, mistakes were coming. Perhaps Nightmare Moon should have been able to get herself under control and milk those balls dry, rather than gagging on her powerful shaft. Perhaps, but now, Celestia was the one who’d made a mistake, taking advantage of the situation too eagerly, forgetting to secure the position. Nightmare Moon’s fist smashed between her legs, battering her balls and cunt, and making the princess scream with erotic agony at being sexually battered. A twist of the midsection, and Nightmare Moon’s head slammed her cutie mark like a club. The cutie mark was a sensitive target, the magical energies all pooled in one place on a pony’s flank, and it hurt like hell to be smacked in it. She collapsed on Midnight Moon’s back, arms still draped around her torso, as the dark mare grasped her shaft and started jerking it between her legs. A low moan escaped Celestia’s lips, held back as long as it could, but finally forced out by the pleasure. She was too exhausted to deny how good it felt, despite her shattered ribs and wings, to feel those dark and strong hands massage her cock. She was too tired even to try to escape from the non-hold, she had to just take what she was given for a few seconds, let her twisted sister pump pleasure into her shaft, tease the cum to spurt from her cock.

“I... Hate you...” She panted lowly, as Nightmare Moon milked at her.

“I know.”

A rock-hard shoulder drove into Celestia’s waist, and she was thrown from Nightmare Moon’s back, to the ground. Her damaged wing-bones crunched and shattered under the weight of her muscles crunching down on them. She screamed out in agony, and her sister rose above her like a vision of torment. She was too tired, and in too much pain, to escape. Nightmare Moon raised her foot, and Celestia gritted her teeth, preparing for the attack. Moony stomped on her shaft, compressing the powerful cock beneath her full weight, leaning on Celestia’s waist. Pre juices dripped from nightmare moon’s cock and cunt, but Celestia’s shaft was jumping and bucking, flexing, the princess knew she was going to lose control, soon, unless she could do something about her dark sister grinding in on her shaft. Nightmare Moon slid her foot along Celestia’s cock, leaning forward, her hands on one knee as she dominated her. It was utterly humiliating, the earlier brutality had broken her body, and now her sadistic sister wanted to break her spirit as well, by forcing her to stain her foot with her juices. It was working, her balls bounced, and pumped cum into the shaft of her cock. It was all she could do now not to submit her cum and pride to her cruel sister. But she gritted her teeth and held on, desperate to preserve her cum and pride, even as her cum-filled cock twitched against the foot that milked it. Her head rolled back and she moaned low as she contemplated her situation, and how to escape.

“What’s the matter, sister? Are you... Struggling?” Lust drenched Nightmare Moon’s voice as well as Celestia’s as she taunted her. “Are you aware of... How useless... Your resistance is?” She sounded confident, but her voice was cut off by loud panting. Not that it mattered, as Celestia was about to blow. In one last, desperate assault, she raised her foot to her sadistic sister, slamming it into her cunt! She booted her hard from the ground, and was met with a gratifying gasp, as the musclemare fell to the ground. Celestia was in little position to capitalize, rolling onto her side, and staring at the form of her midnight black opponent. Even freed of her attack, her cock was twitching, and she was nearly cumming even without the contact. She reached between her legs and clutched her bucking shaft, her knees drawn up protectively, her hips pumping without control. But the sadistic bitch got off on feeling pain as well as giving it, a mean little masochist who deserved all the pain she got off on. Celestia’s whimpers as she struggled not to cum, the pleasure in her straining cock drowning out the agony her beating had given her, were likely making things at least horribly erotic. For now, though, Celestia was too paralyzed by fighting to prevent an orgasm that had already started from bursting forth, bucking her hips and biting her teeth, to fight more. She prayed with all she had that her sister was as tired as she was, as her cheek rested on the ground, dark eyes glaring at her.

“You’re already cumming, sister... You powerless bitch.”

“Sh-shut up...” She gasped out through clenched teeth.

“You’re fooling... Yourself if you... Think you c-”

The white princess snarled, and a blast of golden magic shot from her horn, smashing her sister across the face. Harder than she’d expected, the black mare’s head rocked to the side, and when she looked back her face was swollen. Celestia enveloped herself in an envelope of her own magic, prepared for the attack. When Moony leaped at her, snarling like a furious beast, Celestia used her own telekinesis to counter. She slid downwards, her broken wings raking the ground, mangled on the lunar surface, so she could position her head perfectly. As Moony’s thick cock came down, her open mouth was under it, to take it to the hilt like a sword-swallower. It expanded between her lips, the powerful shaft swelling in her. She suckled hard, enveloping it with her throat-muscles swallowing, and bathing it with her saliva and tongue. Nightmare moon cried out like she’d been shot, grabbing her head and pushing at it, but Celestia held on like a lamprey, magically binding them together so her oral assault could continue, and both hands were free to hold back the creamy tide. The pre got saltier, the bitch was about to blow.

Finally, Nightmare Moon happened on a solution, and grabbed Tia’s magic-enveloped horn. The white mare gasped, the pleasure almost short-circuited her mind. Instantly, she used the last blast of magic she had to knock Nightmare Moon to the side. Both mares fell away from each-other. Celestia rolled, her cock clenched tight in one hand, like she could crush back down the flow. She saw Moony was doing the same, her draconic eyes blazing as they glared at each-other.

“You... Bitch... You’ve... Gah...” She didn’t need to say too much. Celestia knew exactly what she’d done. The bitch was in the same state, cum filling her shaft. She growled at her. It was time for the pair of them to finish this. A wordless agreement reach, they leaped at each-other, arms outstretched.

Tia went high. Moony went low. Moony won, her mouth wrapped around that huge cock, stopping the other alicorn dead in her tracks. No longer protected by her hands, her huge cock was easy prey to the skilled mouth of the other princess. Celestia grabbed her ears, the rest of her body out of her control, she fucked her face, head rolled back. Tears fell from her eyes, as she struggled to hold back an already started orgasm in the face of one of the most skilled cocksuckers in the world. It was a fool’s errand, but she did it all the same, praying that the one or two extra seconds she could buy would be the difference between a victory and defeat. She doubted it, weeping as she pleaded softly

“Cum... Just cum... Just cum...” Her efforts to hold back were being battered away by the second, with each thrust she gave into that hungry mouth. Still, she held back, until Moony seemed to spontaneously hit upon the answer. She practically screamed around her cock, and Celestia’s shaft gave in. Tormented for too long, it gave up what it had been trying to store in its balls for so long, and shot a burst of seed so deep into the wicked woman’s mouth that the cum rolled out the side and down her cheeks. She had held back longer than any mortal could, longer than most immortals could. Her fight was over, and she just ground her foes face to her shaft, enjoying what she could of the orgasm. Her cum spurted more and more, pumping out what her sister had wanted so badly. She held Luna’s face to her hips, smothering her with her womanly form, as she gave up what she’d been holding back so long. On and on her orgasm went, splashing out on her hips, waterfalling off Nightmare Moon’s chin, onto the ground. She still held her by the ears, even after she came, even as her muscles began to relax, as if doing so would keep the match from being over, save her from the defeat, until she felt Moony’s hand on her hips, and remembered what she was doing.

She fell back, exhausted and crying, her cum all over her lower body. She couldn’t bring herself to even look at her conqueror, as she stared into the sky. She felt a strong arm wrap around her chest, a warm body press to her side.

“Fine... You win... Do what you want.”

“Actually...” The voice was higher, and she turned to see her younger sister, cum dripping from her lips, “I came a couple seconds before. Why did you think I screamed like that?”

Celestia laughed, “You did? I thought.”

“Well, you thought wrong. And unlike my evil side, I’m gonna be honest about it.” Her isster snuggled up close to her. “Soo.... What do you want of me?”

Tia gave a girlish laugh, though not too much of one, as even that hurt her broken ribs. Her sister winced. “Sorry...”

Tia shook her head. “It’s fine. And I think I’ve gotten all I could want of you.” She nuzzled her nose, feeling her own cum dripping from Luna’s muzzle. Luna laughed. “I’ll see you soon, Sister.”

Tia nodded, “Will you?” She asked.

“Of course. Time to wake up.”

The massive mare rolled over in bed. The pain was gone, but the memory of it still made her tread delicately, as she rolled to her side, eyes squinched shut, as if shutting them tighter would make herself go back to sleep. After a second or so of that, something fell, and bounced off her cheek. She gave a groan that, maybe, had been intended in some way to form words, but had ultimately been just a random sound, as she grabbed it.

It was a scroll. Great. It took a couple tries to undo the seal, and when she finally did, she was met with illegible scribbling. She shook her head, trying to get enough clarity to read the words on the page. It took some time, before she finally made them out.

“My Dearest Teacher,

My continuing studies of pony magic have led me to discover that we are on the brink of disaster.”

“Only time Susan Fourmanes was any good,” she mumbled not sure if the joke landed or, indeed, was accurate.

“For you see, the mythical Mare in the Moon is, in fact, Nightmare Moon, and she’s about to return to Equestria, and bring with her eternal night! Something must be done to make sure this terrible prophecy does not come true.

I await your quick response.

Your Faithful Student,

Twilight Sparkle.”

She grumbled, grabbed a pencil and paper, and scratched out an answer. After a few false starts, she finally settled on.

“Dear Spike,

Tell Twilight to stop fucking around and get out of my mane. How about this. Help them set up the thing in the nudist colony. Ponyville. Whatever. Girl needs to get laid. Or at least make some friends. But, you know. Make it sound all fancy. Too tired. Going back to sleep.

Your Princess,

~Princess Celestia”

There. Oughta fix that. She looked out the window, and smiled.

“See you soon, sister.”
