Chapter 1

Twilight rushed into the throne room as fast as her hooves could carry her. “Princess Celestia, Princess Luna!” she called as she ran. “What’s wrong? I came as fast as I could!”

Celestia addressed her gravely. “Princess Twilight, thank you for coming. I fear we may have been lost without you.”

“Indeed,” Luna said. “Love is spreading throughout all of Equestria.”

Twilight slowed to a premature halt. “Wait... Isn’t that a good thing?”

Luna shook her head. “There can always be too much of a good thing.”

With her hoof, Celestia pointed to the back corner of the throne room, a place that hadn’t drawn Twilight’s attention until now. “Cadance has already taken our Royal Guards.”

In that corner was a huge pile of Royal Guards – stallion, mare, and everything in between. A literal fuckpile. It was hard to make sense of it all, through all the awkwardly placed limbs and bodies. The fuckpile leaked all sorts of unspeakable fluids onto the throne room floor, and it still writhed a little from the efforts of the few Guards who still had enough stamina left to keep doggedly going at it.

Twilight gulped. She was no blushing virgin, but she was not accustomed to such indiscriminate debauchery. “Princess Cadance did this? I see...” It only took a moment’s thought to come up with a solution. “I should get my friends! With the power of friendship, we’ll—”

Celestia pressed her hoof on a particular tile of the floor. It depressed like a button, then gave way to an opening trap door, allowing a crystal ball on a pedestal to rise out of the floor. Dreading what she might see, Twilight looked into it.

She needn’t have worried. It was only a view of her castle in Ponyville, currently empty-looking. No motion there.

It did make her scrunch up her face a little, though. “Hey... You can spy on us anytime you want?”

“I only use it for the most noble of purposes,” Celestia assured her. Luna snorted a little, which drew Celestia’s momentary ire. “You have little room to speak concerning the privacy of Equestria’s ponies, oh Princess of Watching Ponies’ Dreams.”

“Shall we instead focus on this more pressing matter?” Luna suggested.

“Yes. Let’s.” Celestia turned back toward the crystal ball. “Now, where are they...?”

“My friends!” Twilight all but shouted. “Are they there? Are they okay?”

Various scenes flashed by in the ball’s depths, but they never showed the ponies Twilight wanted to see. Celestia looked up at her. “This scrying spell is powerful, but it can only be targeted on physical locations, not ponies. Do you know where they would be this time of day?”

Twilight thought for a moment. “The spa! Fluttershy and Rarity always always have their spa day this time of the week. They’ve got to be there!”

The view in the crystal ball shifted. One empty massage room, empty lobby, empty sauna ... hot tub!

“There they are!” Twilight shouted, forgetting herself. “They’re...” Her eyes went wide as she truly realized what they were doing. “Oh... Oh no...”

Rarity and Fluttershy were sitting on the edge of the hot tub, their hind legs dangling into the water as they passionately made out with each other, as if they just couldn't get enough of each other’s lips and tongues, not to mention their hooves roaming all over one another’s bodies. And down below them … there were Aloe and Lotus, present and accounted for: each of them with her muzzle nestled close between one her friend’s legs, making out with their nether lips just as passionately as the kiss above them.

“I take it this is not usual behavior for them?” Celestia prompted.

“No!” Twilight shook her head as if trying to clear the vision, but it stayed there in the crystal ball. “I... I don’t really know about Fluttershy. She’s very private about it. But I know Rarity is straight as straight can be.”

“Much to Applejack’s dismay,” Luna quipped.

Twilight stared at her. “Applejack dreams about Rarity?”

Luna chuffed out a little laugh. “You should see the dreams she has about Rainbow Dash.”

Twilight was already learning far more than she’d ever really wanted to. In a strange way, it made her gain a new respect for the things Luna had to see every night. “Does... Does she dream about me?”

Suddenly, Luna made as if to look entirely noble and regal. “It would not be proper of us to say.”

“Focus!” Celestia insisted. “This is why we three must act quickly and decisively, before even more love spreads and Cadance gains more power. Only alicorns such as ourselves have any chance of resisting Cadance’s love magic.”

Twilight shook her head, rubbing her face with one hoof. “Why would she do this? Are we sure it was her?”

“We observed her vanquishing of the Royal Guard ourselves, before our very eyes.” Luna sounded a little rattled by the experience. “We still have not managed to interest any of them in anything other than … what they are currently doing.”

Celestia nodded. “She was different. Her coat has gone nearly black, and her colors have changed. But it was most certainly her.”

“But...” Twilight’s jaw dropped. “But that sounds like...” She glanced over at Luna. “Um... Never mind.”

“No, you are correct,” Luna insisted quietly. “It reminds me very much of when I was in the clutches of the Nightmare.”

“Nightmare Cadance...” Celestia grimaced with the distaste of those words. “Sadly, it seems that it can happen even to the best of us.”

Twilight firmly refused to think of what ‘Nightmare Twilight’ might look like. She had a feeling that she’d been all too close to finding out on more than one occasion. If it weren’t for the help of her seemingly incorruptible mentor... She shook herself. There was a problem! They needed a solution! “How are we even going to find her? She could be anywhere.”

“She will find us,” Luna said with confidence.

“What? How?”

“My sister is right,” Celestia said firmly. “We are her greatest threat. If we strike against what she holds most dear, she will have no choice but to defend against us.”

“What she holds most dear...” It came to Twilight instantly. “My brother!”

“Exactly,” Luna confirmed. “We must make for the Crystal Empire at once!”

* * *

Things were not any better at the train station.

“She has already been here,” Celestia proclaimed unnecessarily. Twilight herself could see that, given all the trysting ponies surrounding them and, most concerningly, the train conductor busy getting his limp and spent cock sucked by Fleur De Lis. Two more ponies – a mare and a stallion passenger – were going at each other as he licked them both.

“What about the engineers?” Twilight suggested. “They’re the only ones we really need in order to get to the Crystal Empire.”

“Taken as well, I’m afraid.” Luna pointed.

And there they were, two stallions in what was left of railway engineer uniforms, holding each other in a front-to-back position, sixty-nining each other with great enthusiasm.

Twilight tried to ignore the moans and fleshy, squishy sounds of being surrounded by ponies in the throes of erotic passion. It wasn’t easy. She also worked to ignore the slight heat growing under her tail. No – she would not allow herself to be drawn into this! Was all this even necessary? “Can’t we just fly there?”

“It’s too far and too cold.” Celestia gave an involuntary shiver. “It would take weeks. That’s just time we don’t have to spare.”

Luna stared at the train. “I do not suppose that either of you understand how to operate one of these modern contraptions?”

“Sister, we’ve had trains for hundreds of years. They’re hardly modern.”

“Well, I have had trains for less than ten years...” Luna squinted at it. “I still have my suspicions about their use of dark magic.”

“Sister, I told you, they work by burning coal, which in some fashion—”

“I don’t know how to run a train yet,” Twilight said, daring to interrupt the elder alicorn. They couldn’t afford the time a bickering match between the sisters might take. She grinned as she let the suspense build slightly. “But I just happened to spend last summer placing teleportation keys on every book in my library. Hold on a moment...”

She sent her magic touch riffling through the many volumes remotely, found the right target, and brought it to herself with a flash of teleportation.

Celestia picked it up from where it had landed on the platform. Luckily not in one of the many assorted puddles of sexual fluids present there. “Train Driving for Dummies...” She looked over at her sister. “See – I told you Princess Twilight would be must helpful in our quest!”

“I did not doubt that,” Luna said, peering at the book. “I do, however wonder if it is a slight against our intelligence. Was Train Driving for Intelligent and Popular Princesses not available?”

“As a matter of fact,” Twilight said, “it was not.”

“Come along, you two.” Celestia was already trotting toward the front of the train, carrying the book in her magic.

* * *

“Okay... ‘Chapter Three: Preparing the Engine’.” Twilight sighed. “I still think we could use those first two chapters of safety precautions and introduction...”

Celestia looked pleadingly. “There will be time enough for that when we are in motion. Come now, we already agreed to skip the first two chapters.”

“By two to one vote,” Twilight said sourly. Come on. Celestia had been the one who taught her about doing things by the book. And now she wanted to skip what might very well end up being the most important chapters? She shook her head. Whatever. Time to get reading. “Alright then... Princess Celestia, can you pull that big lever on the left? And Princess Luna, I need you to turn that wheel on the right counterclockwise until the gauge above it moves its needle into the green section.”

“Dark magic,” Luna muttered under her breath as she moved to adjust the wheel.

Steam began to hiss.

“It’s working!” Celestia said with actual glee in her voice. “It’s working!”

Twilight grinned in triumph. “Great! Now we need to shove plenty of coal into the furnace grate there, and check the water level...”

* * *

The three alicorns snuck into the entrance gates of the Crystal Palace … though, honestly, there probably wasn’t much need for stealth. The streets of the Crystal Empire had been little more than a giant orgy, and the Crystal Guards at the palace had been too busy having their way with a lovely group of crystal mares to bother stopping the three of them – or even acknowledging their presence.

It was uncanny, Twilight thought, just how obsessed with sex they’d all become. She steadfastly ignored the effects it was having on her own body. Just a natural reaction to seeing everything around her, of course. Nothing to be concerned about. It wasn’t as if she was suddenly going to just give in and go squeeze herself underneath one of those Crystal Guards just because she felt a little tingling heat under her tail. That would just be ridiculous. She was better than that.

They reached the throne room without incident, without even being noticed. All three of them stopped just outside the massive crystalline doors.

“You think he’s here?” Luna asked, a little dubiously.

Celestia sighed. “He wasn’t anywhere else, not in his quarters, nor any of his other usual haunts. If Nightmare Cadance wanted him kept safe, this would be the safest place.”

“Unless she’s already figured out our plan and hidden him away somewhere,” Twilight added.

“Well, if that is the case, then we may not be able to locate him. We’ll need a new plan. But first, we should check the throne room.”

Luna stepped forward and put her hoof to the door, but did not yet open it. “And if Nightmare Cadance – as you named her – is here … have we a plan?”

Celestia shook her head. “Attempt to subdue her. Do our best to resist her love magic. What else is there to do?”

Staring ahead at the door, Twilight quietly said, “I hope he’s okay...”

“Come,” Celestia said. “Our time is limited.”

Luna opened just one of the two huge doors for them … and the moment they came inside, Twilight just knew something was terribly wrong.

Not that it had taken any great leap of intuition, though. The main thing that clued her in was the sight of Shining Armor. He sat on the throne, his hind legs splayed out in front of him and his cock – Twilight tried not to think about how sumptuously big and perfect it looked – standing straight up in front of him. He stroked it with both hooves, ceaselessly repeating Cadance’s name to himself.

She had hoped that Nightmare Cadance – the name started to seem more and more appropriate now – would have spared her brother at least. But no. It seemed that nopony in Equestria was safe from her.

“Does this seem too easy?” Luna said, carefully approaching the throne.

Celestia was close behind her. “She has gone mad with the power of love. She isn’t thinking clearly.”

Twilight was the last in line behind them. She wasn’t sure how close she wanted to get to her brother when he was like this. She didn’t know what he would do. Worse, the wasn’t sure what she might do. “I have a bad feeling about this,” she muttered. “Almost like it’s...”

The door slammed behind them.

“A trap?” A harsh giggle came from behind.

That voice! It was recognizably Cadance’s, but it was just … off somehow. Unhinged. A twinge of desperation in it.

Slowly, dreading what she might see, she turned.

Barely in time! A love laser already beamed toward her – she barely managed to get a shield in place fast enough.

Cadance’s magic was strong now! Twilight could barely hold against it. Her hasty shield was unrefined, drawing too much magical power from her for the good it was doing. If she was alone, she wouldn’t have been able to hold it.

Thankfully, she wasn’t alone. It was scarcely a moment later before Celestia stepped in front of her, blocking the beam with a new, brightly glowing shield … a type of shielding spell Twilight had never even seen before. Amazing!

Luna came around the other side, launching a counterattack that forced Cadance to cease her beam and put up shields of her own.

It seemed that Cadance was not without her tricks, though. Even as she kept her shielding spell up, a strange new spell twisted its way up her horn. It flashed up from the tip, then began to spread like a wisp of smoke. Only … it didn’t thin as it spread, as it grew to fill the huge throne room.

“What is this?” Luna shouted over the sound of her own magic beams spattering over Cadance’s shield.

“I don’t know,” Celestia shouted back. “But put up the best shields you have!”

Twilight did exactly what her mentor said, enacting practically every shield spell she knew, all at once.

It wasn’t enough. The strange, mist-like magic Cadance had cast suffused right through all the shields, as if slipping through cracks between them. Despite all the countermeasures she tried to enact, a little of it still got through to her.

Most of it had been blocked by the ‘ethereal wind’ spell she’d tried in desperation as the mist was about to touch her. That had worked, but a tiny portion of Nightmare Cadance’s magic had touched her.

Even that little touch! She was nearly overwhelmed by the effects of it. Her fur stood on end, her tail flipped up over her back, and beneath it, her pussy was winking like mad. Drips of wetness ran down her hind legs, and she already felt a deep, yearning emptiness inside her.

If she’d been hit by any more of it, she wasn’t sure she would have been able to resist. As it was, she was keenly aware of Shining Armor’s presence behind her. She could still just barely hear him saying Cadance’s name. Was he … was he looking at her, though? She didn’t dare look away from Nightmare Cadance to check, but she thought she could feel his eyes on her, taking in the sight of her desperately winking pussy.

Oh, she and him had fooled around before, exploring as foals do. But it had never gone beyond a few tentative touches. Was that a regret of hers? Had she wished there had been more? Had he? To think of him back there, stroking himself as the stared at her completely exposed vulva... What if Nightmare Cadance did succeed? Did that mean that Shining and her would be left together, both overwhelmed with love magic and unable to restrain the slightest impulse toward expressing forbidden desire in the most carnal way possible?

No! She had to focus! She couldn’t let that happen – no matter how much her body wanted her to. She had to be strong! For Equestria!

Thankfully, Celestia and Luna seemed to be doing a little better than her. The two of them were sticking very close together now, merging their shields while they launched attacks against Nightmare Cadance. They’d obviously gotten a little of the spell themselves – their tails were up and they were winking – but perhaps they were better able to control themselves with centuries of experience, and the arousal hadn’t crippled them to quite the degree it hat affected Twilight herself.

Emboldened by the other alicorns’ resolve, Twilight redoubled her efforts at control, managing to launch a few counterattacks of her own against Nightmare Cadance. Nothing major, but it would help weaken her shields, and anything that served to distract her as Celestia and Luna advanced on her would be all for the better. She didn’t have to let her buried lusts control her. She could handle this!

The other two alicorns were drawing close now. Nearly close enough to lunge at Nightmare Cadance. “You cannot overpower us with your magic as you have the rest of Equestria,” Celestia said firmly.

Luna was right there with her, beginning to grin slightly. Yes! They were winning! “Surrender now, Cadance, and we will be merciful!”

Nightmare Cadance, however, didn’t look worried in the slightest. She practically gloated over them as if she’d already won. “Oh, did you think I would be depending on your mercy?” She let out another shrill little cackle. “No … I don’t think so. I think I’d rather have your love instead!”

She charged up another magical attack, flinging it toward the sisters, but it deflected off their shields easily. Twilight used the moment of distraction to launch a piercing attack of her own – one that very nearly succeeded in tearing through Nightmare Cadance’s shields.

“You will not have our love!” Celestia shouted in near-triumph. “Together, we’re too powerful for you!”

“Don’t you think I planned for that?” The mirth in Nightmare Cadance’s voice gave all of them pause. She smiled sweetly and then stepped on a particular spot on the floor.

An opening in the crystal appeared beneath Celestia and Luna – right where Nightmare Cadance had lured them to. Unprepared for a non-magical attack like this, both sisters suddenly dropped down through the trap door, neither of them able to bring their wings to bear before the door slammed shut again above them.

“Celestia! Luna!” Twilight shouted, running for the spot. But the door was closed, and there was no sign of the other princesses. She spun toward Cadance, raising renewed shields, and she snarled. “What have you done to them?”

“I’ve only given them what each of them has needed for hundreds of years now. Trust me, they’ll thank me for it later.”

Twilight took one menacing step closer. At least she hoped it would be menacing. The way her tail was raised high behind her back may have ruined the effect. “I want them back right now, do you hear me?”

“Oh, you’ll get them back soon enough. First, though, I have my own plans for you.”

“Not on your life!” Twilight darted forward, lunging to take Nightmare Cadance off-guard.

She only stepped slightly to the side, though … onto another hidden panel in the floor. Twilight’s lunge carried her straight down a deep shaft. She only just barely unfurled her wings fast enough to avoid crashing into the floor below. And just as she began to fly back upward … the door slammed shut.

Chapter 2

Even though Twilight knew it was futile, she indulged in a little pounding on the door above, yelling at Nightmare Cadance to let her out. It was, of course, completely ineffective … but she just really needed to work off a bit of the stress.

After that, she finally allowed herself to glide back down the long shaft, past the featureless crystal walls, and into the cell below.

Because that’s what it was. A prison cell. It may have been appointed with luxuriant drapes on the walls, soft carpeting, and plush pillows scattered tastefully around … but there was only one door, and it was locked tight, without any sort of doorknob or handle on the inside. It was just barely translucent enough to sort of see through … but all there seemed to be on the other side was darkness.

She of course tried the obvious: lock picking spells, trying to manipulate the outer latch telekinetically, blasting it with magic … but nothing worked. It certainly was true that Nightmare Cadance wasn’t thinking clearly, but it did seem that she was capable of designing a cell capable of holding an alicorn.

So … what did Nightmare Cadance have in mind for her, then? Was she just going to be left in here to rot? That didn’t sound like something Cadance would do. Not in her state. Surely it would be something love-related, right? So then why the delay? Was Nightmare Cadance focusing on Celestia and Luna’s romantic torment first? Was that it? Even though she’d have to admit the wisdom of dealing with the elder alicorns first, she couldn’t help but to feel slighted a little bit.

Or was that feeling disappointment? Her body raged from the inside out, her pussy still winking insistently. Oh, how she longed for whatever kind of love Nightmare Cadance had in store for her! She’d accept it, take it, anything to cease this—

No! Shaking her head, she fired off cleansing spell after cleansing spell, trying to free herself from the effects of the curse. But it was no use. Cadance’s spell had only activated her own body. The spell was long gone, and all the lingering effects were just Twilight’s own body betraying her.

If only she’d had centuries to master the art of self-control like Celestia and Luna had! She’d bet that they weren’t in their cell pining for Nightmare Cadance to send some lover to satisfy them! Surely they’d already mastered themselves and were working on an escape plan. As she herself should be. Only...

“Ugh!” She groaned, flopping down onto one of the pillows. Maybe if she just clopped herself very quickly, then she’d be able to think clearly enough to actually get out of here!

That wasn’t simple, though. As soon as she started touching herself, images of her brother’s cock came to mind, of him stroking it. No! She scolded herself. No, she couldn’t have that. She never could, not in the past and not in the future. If she could only stop thinking about it!

Think about Flash Sentry instead! She forced herself to think of the young man she’d met in her trip through the mirror into the human world … but it just wasn’t doing it for her. She’d never seen him naked, never seen him like that, stroking himself while staring right at her. And besides, those human bodies were just... Well, they were okay, but the proportions were all gangly and wrong. And Pinkie had shown her some of that world’s pornography while she was there. Human cocks were just … just tiny really, and strange-looking. She could imagine what Flash’s cock might look like for a few moments, but every time she really began getting into it, she’d find herself imagining a big, hard horsecock instead … and before she knew it, that was her brother’s cock, and then it would be on her brother, looking at her as he stroked it, as she stroked it, as—

No! She stopped herself, yanking her hoof out from between her hind legs and standing up again. Come on! Why couldn’t she just keep it together? Why couldn’t she control herself? The effects of Cadance’s spell were over! She should be able to get on top of this!

No! No again! She blocked out the mental image of her getting on top of Shining’s cock as he kept on stroking it just like she’d seen... No. She had to stay focused! Focused on—

High above her, the door opened again. She looked up, already unfurling her wings, ready to fly to freedom. Just in time to see Shining Armor hurtling down toward her, screaming all the way.

Instead of taking flight, she lit her horn, managing to catch him and slow his descent just quick enough. He still landed on one of the pillows rather heavily, but not hard enough to hurt anything.

And by the time she looked up again, the door above slammed shut.

“Shining!” she said, turning to her brother. “Are you okay? Did you—”

“I’m fine,” he said, picking himself up out of the pillow’s fluff. It had burst a little when he landed. He looked at her. “Oh thank goodness you’re here, Twiley – Cadance has gone crazy!”

“You’re … you’re you again!” Overjoyed, Twilight ran to him, wrapping her hooves around him and holding him close.

He hugged her back, holding her very close. So strong and snug... Despite her efforts to ignore his warmth and his stallioney scent, Twilight felt her tail rising even higher.

She tried to pull away from him, but he held her tightly. “Please,” he said. “Please don’t leave me alone. I don’t want to be under that spell again.”

Giving up her efforts to leave, Twilight hugged him again, nuzzling her face along the side of his neck just as she had when she was a foal. “I won’t leave you. Not ever.”

“Love you, Twiley.”

Why did that have to send such warmth coursing through her body? It was completely innocent! He’d said the same things so many times before. It shouldn’t be getting her excited now. If only her body would cooperate! “Love you too, BBBFF,” she said in return. Just the same kind of innocent thing she’d always say to him. No other meaning. No other meaning.

They pulled back a little, still holding each other, but now looking into each other’s eyes with a warm smile.

Shining leaned down closer, kissed her on her lips.

For a brief moment, she melted into it, her body rejoicing at the intimate touch of a stallion, especially one who felt so familiar and safe. Only a moment though.

When it finally got into her head what she was doing, just who she was kissing, she leapt backward. “Shining! No! Wh-what was that?”

He took a step toward her, looking genuinely hurt. “Twiley...”

She wanted to go back to him. Oh how badly she wanted it! She wanted to hold him, to comfort him, to stroke— No! She stopped herself again. No! And that’s when she saw it. The slight pink gleam of the love spell in his eyes.

Okay, no. No! She had to get out of here! Rushing to the door, she tried her whole litany of spells again. Of course nothing worked. But there just had to be a way! Because if she was trapped in here with him much longer, she just might...

No. No. She wouldn’t even think about it.

Shining was sure thinking about it, though. He came up behind her. “Twiley,” he whispered softly, “I need you.”

Her pussy winked hard at that, but she forced her tail to clamp down over it. Instantly she felt the wetness against the underside of her dock. “We need to get out of here!” she insisted. “Before... Before, um...” She clamped her tail down again – it had started to stubbornly rise. “We need to get out as soon as we can!”

“Twiley...” He rubbed his head over the top of her rump, his cheeks rubbing against her curves.

There was just no stopping it, not with that kind of warm and tender feeling, that kind of implicit invitation.

She couldn’t even bring herself to do anything when he pressed his chest against her from behind. The feeling of his warm chest fluff against her needy pussy was just heavenly. And when he slid up over her, grasping his forelegs around her, he just felt so powerful, so sure of himself. She could just melt against him, just let it happen. Oh she wanted it so much! When he nudged his hips forward, when the tip of his hot cock met just the perfect place, instantly plunging slightly inside her … that was when she finally woke up.

“Shining, no!” She darted out from under him, letting him slip back down to the floor. Her pussy winked like crazy underneath her tail, betraying her need.

He looked at her pleadingly. “Twiley, please...”

Oh that look on his face... The love spell must have been taking such a terrible toll on him. And he just looked so cute begging her like that. And after all, it wasn’t as if they’d never fooled around before. Maybe if she could just satisfy him a little bit...

“Look,” she said. She gulped and licked her lips. “Um... Will you be able to get your mind back in the game and help me open this door if I...” Deep breath. “if I just suck you off really quick?”

“You’d do that?” He rushed to her, hugging her again. The warmest, most genuine hug she’d ever felt. “You are the best sister ever!”

“Okay...” She slipped back down to the floor and nuzzled him a little. “Just make this quick, alright? We still need to get out of here.”

He nuzzled the back of her neck as she began to lower herself down underneath his belly. “Oh Twiley... You feel so nice...”

She hadn’t even touched him yet! Well, not the part that mattered, anyway. And that part that mattered … well, there it was. Right in front of her face now, throbbing and thumping up against his belly. Oh, he must have been so turned on! It wouldn’t be bad to just give him a little help, right? It didn’t matter that she was winking like mad under her raised tail, or that the feeling of him nuzzling his way down her back made her breath come short, or the way looking at his slightly upward-curved length made her legs feel weak.

Of course, it was only for his sake that she went to it so quickly, dipping her head down and taking his tip into her mouth. She just needed to get his mind off this. And maybe, well, get her own mind off it. His thick tip filled her nicely. So warm, so firm, and yet the skin was so delicate and soft. She slid her tongue along the bottom of his shaft, beginning to bob her head down lower on him.

Shining moaned softly. “Oh Twilight … so much better than the last time...”

The last time was when she’d just been a curious foal and – without knowing why at the time – wanted to find out what he tasted like. Oh, now that she’d had a little experience behind her, she could do so much better! She’d really show him how it was done, and she’d have him getting off in no time! There was some pressing reason for that, but it escaped her at the moment. What was driving her on at that time was the prospect of a big, heavy mouthful of her brother’s cum. She wasn’t sure why she was craving that so much, but it seemed like that would just hit the spot perfectly … and then maybe she could clear her head, too.

Soon, she was taking almost his entire length, sliding up and down slowly and luxuriantly. She’d taken smaller stallions down to the hilt before, kissing the sheath … but Shining Armor was a little on the bigger side. She couldn’t quite make it.

He didn’t seem to mind her missing the base of his cock, though. Groaning with satisfaction, he explored her body with one forehoof, sliding it over her back, around under her belly to tease her teats … and, of course, down around the curve of her ass.

Twilight let out a little moan of her own, squeezing it out around the girth of his shaft. Shining hadn’t hesitated at all to reach right under her tail and rub her pussy lips. How did it feel so good? She’d been touched before … why had it never felt like this before? The tingling pleasure shot through her whole body, emanating from under her tail but coursing through every part of her from hoof to horn. And it felt so wet and slippery back there. She’d only ever felt like this after using too much lube or something.

“Oh Twiley,” Shining said softly from above and behind her. “Why did I never realize how sexy you are?”

She wasn’t exactly in a good position to respond – her mouth was full. She gave him another little moan, though, pressing herself as deep as she could go on his cock, letting it slide far up her throat. The tender way he was petting her pussy made her want to get him deeper, want to please him as well as she could.

And it was working. She felt the bulge growing in her throat, his flare beginning to spread and choke her. She didn’t stop, though, even when her eyes watered and even when she couldn’t breathe anymore. She knew he was close. And his orgasm – now the only goal in the world she could think about – would be only moments away. She could do it. She could give it to him.

“Twiley!” Shining moaned deeply, pressing his hoof against her pussy and rump to push her deeper.

She let him, and she let him hold her there. Her pussy winked against his insistently pushing hoof, and just a little more of his length squeezed down into her mouth.

And then it throbbed. Twilight swallowed greedily, gulping down thick wads of her brother’s cum as fast as he could pump them into her. She could feel the thick tube along the underside of his cock pulsing with warmth, and she could see his beautiful, bountiful balls clenching right in front of her as they unloaded into her mouth.

She wasn’t done yet, though. Overpowering his push from her rear, she pulled back most of the way off of him, his still-pulsing cock glistening with her spittle. Just in time to catch the last few small spurts of it on her tongue, to taste his musky, salty flavor. Her pussy winked hard against his hoof, as if begging him to push it inside her.

But instead, he collapsed down onto one of the pillows, belly up and breathing hard. “Oh Twiley... Oh fuck... You’re so ... so... Mmmm...”

Her pussy winked again. She ached inside. A muzzy fog filled her head... She just had to get herself off if she was going to even have a chance of thinking clearly!

And oh, look... There was Shining Armor right there. His cock laid wet and limp against his thigh, but he could still help her in other ways...

Without putting any further thought into it, she climbed the pillow he’d collapsed on, swung her hind leg over him, and mounted his face.

“Mmm!” Shining said, his mouth full of sopping-wet sisterly pussy.

Twilight reached down and grabbed his horn, using it to hold his muzzle against her burning need. “I need this, Shining.” She moaned a little as his lips began to move against her slit. “And … and you owe me one.”

He didn’t put up any further fuss, opening his mouth and venturing his tongue slightly inside her, letting her juices slowly flow down into his mouth.

She rubbed herself on his face greedily, holding him steady with his horn, guiding him exactly where she wanted him … even though that wasn’t totally clear, even to her. She wanted his lips on her clit! She wanted his cute snuffly little nose rubbing along the outside of her pussy lips! She wanted his tongue plunged deep, deep inside her. It wasn’t deep enough! She had an aching need so far inside, right down at her core, and he just couldn’t reach it!

And that only made her ride his face all the more desperately. She needed more, so much more! Yes, she could get off like this – she already felt close – but it wasn’t touching that deep core of pent-up lust deep inside her. It wasn’t getting where she needed it! The only thing that could would be ... would be...

She glanced behind herself. Yes! Oh thank heavens yes!

Apparently, Shining had enjoyed being fed a hearty helping of his sister’s pussy, because his cock had grown again, emerging back out of his sheath to something quite nearly full mast.

She licked her lips. It didn’t require any thought, any consideration of the possible consequences. All that mattered was sating that deep need inside herself.

Shining let out a plaintive little whimper at first as she slid down off his face, but as she kept working her way down his body, as she neared his cock, that turned into a gasp of awe.

“Twiley,” he said desperately. “We... We’ve never...”

Twilight rubbed her soaking entrance against the tip of his cock. “We did, actually. Just a few moments ago. Don’t you remember? When you got up on my back and tried to put it in? Some of it did go in.”

“But … but that wasn’t—”

She pressed herself a little way down on him, her pussy lips opening around the tip of his cock and letting him get inside her just about as far as he had before.

“Oh... Oh Twiley.” He stared up at her adoringly. “You feel so good.”

“Just give me what I need.” With one long, sensual push, she slid down his shaft, letting it gradually slide up into her. It filled that yawing emptiness inside her, filled her perfectly. She didn’t stop until her pussy lips pressed down against her brother’s sheath. That’s where she paused, holding him there as deep as he could possibly be inside her.

His cock throbbed and moved a little inside her. His forehooves stroked up and down the curves of her body. His lips opened in a state of pure overwhelmed bliss. But he still seemed to understand just what was going on. “Twiley... I love you, but … but we’ve never done anything like this before. Are you sure it’s...”

Moaning, Twilight began to move back and forth on her brother’s lap. “I’ve never been more sure of anything in my whole life!”

At that point, Shining must have either agreed with her or just given in to the pleasure, because he flopped his head down against the pillow, groaning as she moved on top of him. He kept his hooves on her hips, though, squeezing the softness of her as she moved.

For Twilight, it was a truly transformative experience. Never before had she felt such a need inside of her, and never before had she felt it so fulfilled. She could feel every last little bit of her brother’s cock inside her: the blunt tip of it teasing her cervix, the medial ring squeezing back and forth across her inner walls, the thickly veined base of it rubbing her entrance in just the right ways.

She braced her forehooves against the pillow on either side of him, quickly beginning to move faster and faster on top of him, constantly yearning for just a little more of that sweet satisfaction she was finally getting. Her inner walls tightened around him, increasing the sensation even more.

Yes! Oh she was getting so close! Just a little more and...

“Twiley! Gonna … gonna cum! I can’t hold it!”

Already? It couldn't be! But she was already so close! “No!” she cried. “Just a little more!”

“Can’t...”

Could she keep going? Despite all the contraceptive spells in Equestria, she’d never actually let a stallion finish inside her before. Could she really let her brother be the first?

Did she have any other choice? She needed this! Once again, she started moving on top of him, his thick cock churning inside her.

“Twiley!” shining said desperately, now trying to push her up with his forehooves.

He wasn’t able to. From above, she had the advantage of her weight helping her … that, and she had a slight suspicion that he didn’t really want her to get off of him. And she sure wasn’t about to give up what she needed so badly! Already, her legs were tensing up to the point where they hurt. Her pussy was squeezing. Just a moment until...

Shining let out a desperate moan, his body jerking as his cum surged into her, coating her womb for the very first time.

The throbbing of his cock – and the knowledge of what it meant – finally set Twilight off as well. Her pussy clenched down hard around his shaft, milking it out of him, filling herself with his sweet warmth. And the orgasmic bliss exploding inside her sent that warmth coursing through her whole body. She had always been so close with Shining, but now, for the first time, she finally felt like she was one with him. The two of them were joined in an ecstasy that seemed to just keep coming and coming, each of them triggering aftershocks of it in the other.

Eventually, though, there were limits to what the flesh could provide. Even though he still gasped and trembled, Shining’s cock began to subside, growing soft inside her. And even though Twilight still shuddered and moaned, her tired inner muscles finally gave in to the fatigue. Shining’s cock slipped out of her, flopping limply against his leg again. This time, a small wave of cum fell from her pussy along with it. She shuddered again as she felt the warmth of it drip down her inner thighs along the side of Shining’s body.

She looked down at him. He looked back up at her. The two of them gazed into each other’s eyes as both of them breathed deeply, desperately.

And behind her, there was a slight sound. Crystal sliding against Crystal.

It felt wrong to tear her eyes away from Shining’s, but she couldn’t help but look.

The door was open! She stared at it, her jaw dropping. Then she realized what had triggered it.

“A door that’s unlocked by mutual orgasm...” She shook her head, beginning to pick herself up off her brother. “Only Cadance could think of something like that.”

“Cadance!” Shining yelped, suddenly leaping up off the pillow. “Is she going to be okay? Where is she? What if she—?” He just happened to glance down under Twilight’s tail, where she still winked a little as she dripped his cum. “Oh... Oh no. What if she finds out about what we did? She’ll … she’ll...”

“She’ll be fine with it, I’m sure. She was the one who threw you down in here with me, isn’t she?”

He nodded slowly.

“She must have planned all this out in advance. Come on. We’ve got to find Celestia and Luna. Maybe with all four of us working together, we can finally do something to stop her!”

Chapter 3

Locating Celestia and Luna turned out to not be terribly difficult. Once Twilight left her own prison cell, she entered a tiny hallway, just long enough for one more door and an opening into a long stairwell upward. The other door looked exactly like the one that had just been locking her inside. She would have known it was Celestia and Luna’s cell even if she hadn’t heard their voices screaming from the other side.

“Shining!” She yelled. “Help me open this door – they’re being tortured in there!”

There were no door handles or visible latches on the outside of the door, either. And to his credit, Shining Armor tried a few spells of his own – mostly amateurish stuff compared to the powerful spells of unlocking and opening she was trying … but of course, none of that was effective.

The voices inside reached a fever pitch just as Shining exhausted his limited vocabulary of spells. He listened at the door. “Uh, Twiley … I don’t think that’s actually torture you’re hearing...”

“But what else could they—?”

The door opened on its own, revealing Celestia and Luna – both sweaty and panting – on their way out.

When they spotted Twilight and Shining Armor, they stopped short, Celestia first and then Luna a scant moment later.

Luna was the first to wipe her lips and muzzle into some semblance of cleanliness, though. She cleared her throat and jabbed her sister in the side, which led to Celestia hastily doing the same.

Celestia cleared her throat once her muzzle at least wasn’t dripping anymore. “Hmm... What do you say … we won’t inquire as to how you opened your door if you do not inquire as to how we opened ours?”

Twilight glanced over at Shining. She held her tail close down against herself, hoping she wouldn't drip any more cum … at least not where Celestia and Luna could see it. “Sure. That sounds fair.”

“Now...” Luna looked toward the stairwell. “Let us seek out Nightmare Cadance once more and end this!”

* * *

This time in the throne room, Nightmare Cadance awaited them without subterfuge. She sat on her crystal throne with her hind legs crossed in front of her, and she smiled sweetly when the three princesses – and her husband – ran inside, horns already blazing with defensive spells.

Cadance, however, didn’t move. She smiled at them all and nodded politely. “Welcome back, everypony! I’m glad to see you all together.”

“Stand down, Cadance,” Celestia said, “or we will end this.”

Cadance only shrugged. “What? You want this to end? Has your trip to my lungeon not changed your minds?”

For a moment, Celestia was taken aback. “… Lungeon?”

Luna sighed and rolled her eyes. “It is a portmanteau, Sister. Love dungeon.”

“Finally!” Nightmare Cadance grinned. “Somepony gets it! Let me tell you – it took quite a few workers to convert the old trap dungeons from Sombra’s reign into something more suitable for my own purposes, and none of them ever understood that without asking. Bravo!”

Twilight shook her head. “None of this matters! Cadance, you have to stop this now, or we’re going to make you stop.”

Nightmare Cadance looked positively hurt by that … in a condescending, melodramatic way. “Oh come now. Did the experience teach you nothing?”

“Well...” Celestia glanced at the other two princesses before leveling her gaze at Nightmare Cadance again. “I suppose we all have discovered some new things about ourselves...” She shook her head slowly. “But Cadance, this must stop. You’re bringing Equestria to a grinding halt! Ponies can’t do anything but have intercourse with each other all the time. We cannot survive like this!”

Twilight took a deep breath. This was going to be hard to say, especially in front of the other princesses. She hoped they wouldn’t think her a traitor for it. “Honestly, I’m not totally sure I want this to stop entirely...”

“But please,” Luna added, “be more reasonable about it – let ponies take a break to eat, sleep … maybe even work and seek to better themselves.”

“You would want ponies to sleep, wouldn’t you?” Nightmare Cadance said with a sigh.

“We all do,” Twilight insisted. “Equestria is going to fall apart if ponies can’t sleep … or do everything else they need to. Can’t you see that? What’s happened to you, Cadance?”

“What’s happened to me? I’ve seen the light, that’s what’s happened to me! These moments of passion are the best parts of any pony’s life. Surely you’ve seen that now, surely you know! You would not have been able to leave your cells if you had not discovered it for yourselves. Why shouldn’t ponies enjoy such perfect moments as much as possible? I’m turning Equestria into the most wonderful place in the world! A place of constant ecstasy! But if I let you three have your way, Equestria will be nothing but a—”

“Cadance,” Celestia said, he strong voice cutting through Nightmare Cadance’s rant. “I have a proposition for you.”

Nightmare Cadance seemed a little taken aback to be interrupted in her own throne room, but she leaned forward. “Yes?”

“If we promise to stop trying to vanquish you, will you promise to make sure your love spreading doesn’t harm anypony?”

Twilight looked at her, gaping. “You … you can’t be serious!”

“I’m entirely serious,” Celestia said, the tone of her voice proving it as much as it was possible to be proved. She kept looking straight ahead. “Cadance?”

Nightmare Cadance squinted down at Celestia. “How do I know this isn’t a ruse? That you won’t go behind my back and try to defeat me once my guard is down?”

“What?” Luna’s voice squeaked with indignation. “Do you no longer trust us? The most upstanding ponies in all the land? What do you want, a contract signed in blood?”

Grinning, Nightmare Cadance looked down at them all. “No, not in blood. In something more powerful – more primal.”

“So you’ll accept the truce?” Celestia asked, stepping forward to draw Nightmare Cadance’s attention back to herself. “So long as we sign the contract to your liking?”

After giving all three other princesses a long, piercing look, Nightmare Cadance nodded slowly. “Yes. Yes I will. Are you prepared to sign? All of you?”

Celestia nodded first, followed by Luna … but Twilight wasn’t quite so sure. “What exactly are we going to be signing with?” she asked.

Nightmare Cadance chuffed out a little laugh. “Well, I suppose I might as well demonstrate it on myself first...” Her horn glowed brightly, with a distinctly odd pattern to it. It was love magic, certainly, but the way it curled back down her horn and ran along her body in curving lines was just bizarre. Almost like some strange combination of love magic and transformation magic.

All those glowing, curving lines wound their way around her body in unexpected ways, all following their original curve unerringly … and yet, they all seemed to find their way down between her legs.

And she graciously spread those legs for them, so there would be no ambiguity at all about what was happening. Twilight could see everything her sister-in-law had to offer down there – teats, vulva, everything. Soon, though, the list of what she could see grew rather more extensive. In the space between her teats and her pussy lips sprouted a glowing sheath and pair of balls … quite sizable ones. And as the glow faded, leaving real flesh-and-blood organs in its wake, Nightmare Cadance’s cock began to emerge from her sheath, quickly rising to a very impressive size.

“Oh,” Twilight said simply.

“You’ll do it?”

Twilight nodded. She’d heard of such magic, but she’d never been able to see it in real life before. This was actually … well, she wouldn't admit it to anypony, but it would actually be kind of exciting to try it out.

“Wonderful.” As Nightmare Cadance sent her special magic spiraling out around all three of the other alicorns at once, she turned to her husband. “Shining, honey... Write up that contract for us, won’t you dear? You heard the terms.”

Shining Armor saluted and rushed to the royal secretary’s desk, already pulling out paper. Was he still under Cadance’s spell, or was he still just that loyal to her? Twilight had no real way to tell.

Soon, though, she had more important things to think about. Primarily, the strange new feelings coursing through her body. There was a curiously heavy sort of tingling down between her hind legs. She craned her head around just in time to see the glow fade, leaving behind a thick sheath and a very healthy set of light purple balls.

By the time she looked back up – it was an intensely interesting view, after all – she was also beginning to slip out of her sheath … and Nightmare Cadance was already off of her throne, walking toward the three of them.

“Now,” she said, “while he’s busy writing up the terms, you three had better dip your pens in an inkwell...” She grinned lasciviously, turning to present her hindquarters to them with tail raised. “If you know what I mean.”

Having paid more attention to Cadance during their own transformations, Celestia and Luna were the first to reach her. At almost the same time. Celestia glanced over at her sister. “Well, you are Princess of the Moon, are you not?”

“Despite rumors to the contrary, Sister, that does not imply anything about my erotic proclivities.”

“But...” Celestia raised her eyebrows.

Luna rolled her eyes. “But that does not mean I object to such an arrangement.”

Smiling, Celestia used her magic to pick Cadance up and lay her down on her side, right there on the throne room floor. She took her place kneeling behind Cadance, her already-hard cock getting lined up with her niece’s pussy.

Luna, meanwhile, had also managed to get fully erect – just from the anticipation? – and she laid right behind Cadance, in a sort of spooning position, her own cock nudging up toward Cadance’s tail hole.

And that left Twilight with only one option: she quickly trotted around in front of Cadance, kneeling down much like Celestia. Her new cock – purple, mottled, and huge – laid down across Cadance’s face. Truth be told, after doing this for her brother only a little while ago, she was eager to find out just what it felt like.

As it turned out, she wasn’t the only eager one. Even as the first entry of Celestia’s and Luna’s cocks made Cadance moan, she tilted her head toward Twilight’s cock, expertly taking it in her mouth.

It was then that Twilight learned just how outclassed she was in the blowjob department. Shining must have liked it from her just because it was her doing it … because compared to what he was used to with Cadance, she just was not up to par. Not only did Cadance manage to swallow Twilight’s enormous new cock all the way to the hilt in one easy motion despite all the distractions she was getting from behind, she managed to do so with style. She twisted herself a little as she did it, running her tongue along Twilight’s length in a teasing but yet oh-so-satisfying way. Twilight could feel it right through the root of her cock all the way through her whole body. And when Cadance pressed herself just hard enough against the sheath, she could stretch out her tongue and manage to lick Twilight’s balls a little at the very same time.

Twilight moaned in the sudden bliss … and she wasn’t alone in that. Both Celestia and Luna sure seemed to be enjoying their respective holes, judging from the well-satisfied sounds they made. Did being the Princess of Love imbibe even her pussy and asshole with special ability on par with her mouth? Twilight couldn’t imagine it … but she couldn’t discount the possibility, either.

The four princesses quickly got into the swing of things, building up a complex rhythm between them all. Luna was the slowest, taking it easy with Cadance’s ass. And yet, she kept things in perfect sync with her sister by giving exactly one thrust for each two of Celestia’s. Twilight herself let Cadance mostly set the pace for her, plunging her throat freely down onto Twilight’s cock. What could be better than the Princess of Love’s expertly chosen pace, after all?

The position they were in left Twilight right across Cadance’s body from Celestia, and once their eyes caught each other, it brought a devious idea to Twilight’s head. Well, why shouldn’t she indulge a little? She’d already broken so many boundaries today, and it wasn’t as if a little kissing was any more intimate than rutting the Princess of Love from both sides at once, now was it?

When Twilight leaned far forward over Cadance’s rhythmically moving body, Celestia reciprocated by leaning closer herself. The touch of her mentor’s lips was electrifying to Twilight. Without even thinking about it, she pressed her cock more deeply into Cadance’s throat … which Nightmare Cadance took without the slightest complaint. Unfortunately, though, the kiss was doomed to be short-lived. Just as Twilight first dared to slip Celestia a little tongue, Luna’s voice cut in.

“Oh Sister... Might I have another taste of you?”

Celestia pulled away from the most incredible kiss of Twilight’s life to bend low and to the side instead, where Luna raised her head to meet her, the two of them joining in a sloppy, passionate, incestuous kiss. The two of them didn’t falter in their rhythm inside of Cadance in the slightest.

Twilight might have felt a tad left out … if Cadance hadn’t seen to it that she was taken care of in other ways. The Love Princess’s horn glowed, and Twilight felt the tingling, coruscating touch of Equestria’s finest love magic against her pussy lips.

And it didn’t stay on just her lips for long. After teasing her for just a moment, it plunged inward, suddenly surging to fill Twilight’s entire inner depths. It didn’t stretch her with warm girth like Shining’s cock had. In fact, it took up hardly any room inside her at all. But that didn’t stop it from perfectly massaging every bit of her inner walls, all at once.

Overwhelmed, Twilight lost her balance. She fell over sideways, her cock still inside Nightmare Cadance’s mouth.

Somehow, though, Cadance seemed prepared for that. She got one foreleg out of Twilight’s way just in time, so that she was able to wrap it around her body once she fell. And then with a grip around both sides of her, she drew Twilight closer, down along her own belly.

And that was how Twilight came face-to-face with Cadance’s as-yet-untouched cock.

She took a deep breath. Not because she had any real trepidation about doing what Cadance so obviously wanted her to do with it. And not even because of the incredible job Cadance was doing on Twilight’s own cock. No … Twilight was just worried that her own efforts would pale in comparison to what Cadance was doing. How could she possibly keep up with that?

Well, she wasn’t going to manage it by just lying here, was she? She had to at least make the attempt.

When Twilight took Nightmare Cadance’s coal-gray cock into her mouth, she did her best to emulate the Princess of Love’s smooth, sensuous technique. And she was, of course, only marginally successful. She’d read plenty on the subject, of course, but her practical experience was woefully inadequate compared to Cadance’s. She knew her tongue work was sloppy, and she wasn’t able to get nearly the entire length of Cadance’s oversized cock inside her mouth. It was a wonder that she managed to get any of it all, given the great thickness of it. But she did her best. That was all anypony could ask for.

Celestia and Luna, meanwhile, were having a wonderful time, if the way they kept moaning into each other’s mouths was any indication. They held each other, Celestia stroking her hoof through Luna’s mane while Luna caressed along the side of Celestia’s neck, and even as they kissed each other with more passion than Twilight had ever seen in either of them, they still kept up their harmonizing rhythm inside Nightmare Cadance perfectly.

“Sister,” Celestia said, “I can feel you – I can feel you moving inside of her!”

“And I as well,” Luna replied with a sweet smile before kissing her again.

Twilight may have felt a tiny pang of jealousy. That short kiss she’d shared with Celestia had been wonderful … but it hadn’t been anything like that.

Luckily for her, she had plenty of distraction available – distraction in the form of a big gray cock that very much needed attention. Nightmare Cadance was already beginning to flare a little, not that it slowed her down at all in sucking Twilight’s cock. But being filled by meaty princess cock in all three holes was obviously doing a number on her. Twilight would have liked to think it was her own blowjob skills that were bringing Nightmare Cadance to a boil so quickly, but she knew the feelings on her own cock were far more sensational than anything she was able to give in return.

Still, though, it was enough. Certainly when combined with the efforts of the other two princesses. Nightmare Cadance’s flaring tip quickly became too much for Twilight’s throat, forcing her to pull off of her and start licking along her shaft instead. She hoped it would be enough.

It was. After mere moments, Cadance’s big gray cock flared to its utmost against Twilight’s chest fluff as she lovingly tongued the base. Despite the way Nightmare Cadance’s body stiffened and trembled, the first splash of heavy warm wetness against her fur was a surprise. The second caught her along the side of her neck, but she managed to get into position and catch the third on her tongue, pressing her mouth against the tip of Cadance’s cock just as the next thick stream of it came.

Twilight swallowed greedily, taking the thick, gooey cum down as fast as Nightmare Cadance could pump it to her. Such a rich and creamy load! It lingered as it slid down her throat, tingling a little as she swallowed it down.

And, incredibly, Cadance didn’t neglect her own blowjob duties even through the throes of her own orgasm. She sucked Twilight just as sensually and perfectly as ever, not faltering even for a moment.

Cadance didn’t even pause when she used her magic to float the freshly inked contract over to herself.

Though it was a struggle to think straight given everything Cadance’s mouth was doing to her cock and everything Cadance’s magic was doing with her pussy, Twilight forced herself to concentrate, helping to hold the document steady as Nightmare Cadance used a little more of her magic to move her still-dribbling cock. The tip of it smeared across one signature line, glowed briefly, then instantly dried into a yellowish stain on the paper.

And as good as Nightmare Cadance’s blowjob skills were, it seemed that the distraction of trying to help her with the contract had set Twilight a little behind in the race toward orgasm.

After all, the moans of the other two princesses had grown so deep and needy sounding as the two of them pushed each other harder and harder into Nightmare Cadance’s body.

“Are... Are you flaring already, Sister?” Celestia asked, breathless and unbelieving.

“You can feel it?” Luna gave her sister a deep, passionate kiss as they moved into Cadance together again. “She grips me so tightly – I cannot help but reach my fullest. And...” Luna’s eyes went a little wider. “And Sister! You as well?”

“Yes... I must admit, I … I enjoy feeling you through her.” Celestia actually blushed a little – Twilight had never seen Celestia blush before! “Shall we … together?”

Luna nodded. “Together.”

It didn’t take long. Only a few more strokes of Cadance’s supremely talented tongue. Twilight remained right where she was, her view dominated by Nightmare Cadance’s now-limp cock, lying in a sticky puddle of the corrupted Love Princess’s cum, with even more of it still inside her belly. She’d never felt so invigorated and soothed at the same time in her life!

Celestia and Luna truly did manage to cum together. Somehow. They were just that in tune with each other, perhaps? Twilight couldn’t help but feel a little envious of that closeness as both of them groaned as one, their voices blending together, as both of them came at once. Even their bodies jerked in almost perfect synchronization. Twilight could only imagine the twin streams of alicorn cum jetting in parallel into Nightmare Cadance’s pussy and ass simultaneously.

Had Nightmare Cadance used any sort of protection spell? Or was Celestia about to become a father … or mother? It was so confusing … and so hot. Twilight felt herself finally beginning to flare inside Cadance’s throat as the two sisters pulled their cocks out, each of them spewing the last little spurts directly onto the parchment, where they again glowed and dried, binding them to the agreement.

Now that Twilight was the only one left, Nightmare Cadance was giving her all of her attention. Of course Twilight’s flare deep inside Cadance’s throat wasn’t slowing her down in the slightest. Twilight wouldn’t have expected anything less from the Princess of Love.

That was hardly the extent of Cadance’s talents, though. Not only did she put even more care into her sensual blowjob, the working of her magic increased as well. Now it not only swirled and tingled deep inside Twilight’s pussy, it teased her winking clit as well. It played across her aching, ready-for-release balls, tickled her nipples, and even brushed around the ring of her asshole, spreading its tingling touch to every last intimate spot Twilight had.

She didn’t last long after that kind of assault. Scarcely a moment later, Twilight had met her match. Her cock spewed forth deep inside Cadance’s throat, throbbing in time with the Love Princess’s swallowing. It just felt so good to finally reach that release, to empty herself inside Cadance, that Twilight completely forgot about the contract.

Luckily, Cadance hadn’t forgotten, though. She happily swallowed down most of Twilight’s coursing torrent of cum, but just as Twilight had reached her limit and began to subside, she quickly pulled herself completely off, taking the last little dribble on her tongue … which she then carefully carried over to Twilight, planting it on her horn with a careful lick.

“Go ahead, Twilight,” Nightmare Cadance said. “It’s your turn.”

At that moment, Twilight was reminded strongly of her old foalsitter … a bizarre way to think about the mare who had just swallowed so much of her cum. But Twilight didn’t let that distract her. She slowly and steadily moved herself close enough to the paper to touch it with her horn, making sure that last precious drop didn’t fall off … at least not until it dripped right down onto the final signature line.

When that drop glowed and dried, the whole parchment glowed with magical light, suddenly splitting into four copies.

“We are now bound to our word,” Cadance proclaimed. “One and all.”

Celestia was just now catching her breath. “So … you will immediately begin lessening the effects of your love spells? Such that the ponies of Equestria can still function through their daily lives?”

Nightmare Cadance put on a coy smile. “Well, maybe not immediately...” She looked over at Shining Armor.

He was absolutely pathetic at the moment, sitting on his haunches with his ardently hard cock bouncing under his belly. He stared them all, his mouth watering from the show he’d just been given.

Nightmare Cadance smiled sweetly at him. “I think there’s someone I had better take care of before I lessen this spell.”

Twilight picked herself up and tried to shake some of the cum off of her fur. “Um... Can I help?”

Cadance smiled down at her as well. “I wouldn't have it any other way.”

Soon – shockingly soon, the two of them had Shining Armor sitting on the throne, taking turns deepthroating his cock.

“Try to swirl your tongue a little,” Cadance said helpfully, holding Twilight’s mane out of the way. “Oh nice, yes! Look up at him just like that. Just look how much he likes it.” She pulled Twilight off of him for a moment. “Here, let me show you how to use your tongue.”

Shining groaned in pleasure as Cadance took him all the way down again, her tongue flicking around the base of his sheath.

And as Twilight watched her work, trying to pick up a little of her technique, she just happened to overhear Celestia and Luna.

“Shall we go, Sister?” Luna asked, managing to make it sound entirely serious.

Celestia was more in a mood to play, though. “My room or yours?”

Luna laughed … just a sweet little giggle. “I was thinking more along the lines of on the train home...”

Celestia sighed and embraced her sister. “Why did we wait so long?”

“Come! Let us not wait any longer! If we hurry, we may still be able to use the gifts Cadance has given us before the spell terminates!”

Epilogue

Twilight slumped down into her throne in the Castle of Friendship, looking around at her five best friends, trying to judge their expressions. “And, well, that’s how we made peace with Nightmare Cadance … and that’s why you’re still at least a little bit under her spell.” She’d left out the part about Shining Armor, of course, substituting in a random Crystal Guard pony from her own imagination … but she wasn’t entirely certain they’d believed her.

Rarity was the first to respond: “But I don’t understand, Twilight. What ever was it that made you think that we were under Cadance’s control?”

“Yeah!” Rainbow Dash shouted, darting up into the air above the map table. “She was way too scared to show her pink butt in Ponyville!”

“Hey!” Pinkie shouted back. “There’s noting wrong with having a pink butt!”

“Actually, her butt is gray now,” Twilight corrected.

Rainbow did a quick – very quick – loop around the room. “We would’ve power of friendshipped her and kicked her tail right back to the Crystal Empire if she dared come around here!”

Applejack cut in, trying to settle the others down. “Seriously, Twilight. Why’d you think Cadance had already gone and hornified Ponyville?”

“Well, it’s a little um...” Twilight shook her head. “Well, in the spirit of honesty, I suppose I had better just say it.”

Applejack nodded approvingly.

“We – the princesses and I – looked into a crystal ball in the throne room. We used it to look for everypony in Ponyville... And it needed a specific location. The only ponies who I really knew where they would be were Rarity and Fluttershy. Yesterday was their spa day.”

“Oh dear,” Fluttershy said quietly. Rarity just gulped and shrank down a little bit in her throne.

“I saw... Well, I saw Rarity and Fluttershy, um … kissing.”

“Well that’s no big deal!” Pinkie interrupted. “Friends can kiss all the time, just because they like each other and it’s fun, see?” She leapt over and kissed Twilight – quite wetly – on the cheek.

Twilight held her at hoof’s length. “Yes, they were kissing … and the two spa ponies were, um, eating them out at the same time. Both of them.”

Both Rarity and Fluttershy were blushing furiously at this point, trying to make themselves quite small and unnoticeable, despite the way everypony was looking at them, obviously noticing them.

Rainbow, though, zoomed back down into her throne … possibly just because she wanted to pound her forehooves dramatically on the map table. “What? I specifically asked them, and they said they didn’t do extras! They’ve been holding out on me!”

“You go to the spa?” Applejack sniggered.

“No!” Rainbow planted herself back in her throne, crossing her hooves in front of her and looking away … with a huge blush on her face.

“It’s erm...” Rarity sighed. “Well, I suppose the secret is out anyway. It’s a service they only provide to platinum plus members.”

Rainbow’s jaw dropped. “There’s a platinum plus membership?”

Applejack laughed again.

“Shut up, Applejack!” Rainbow was getting positively red in the face now.

Applejack just looked over at her smugly. “Make me.”

“Wait!” Twilight shouted, using her magic to separate Applejack and Rainbow. Whether they were about to fight or fuck, she wasn’t at all sure … but either way it would be too much commotion for her tastes right now. “So let me get this straight, Rarity. You two do that … every week?”

“Not every week,” Fluttershy said softly.

Rarity nodded. “Yes. Sometimes we bring a stallion friend.”

That pulled Applejack’s attention away from Rainbow. “Y’all had better not be talkin’ about my brother.”

“Don’t be ridiculous, darling. We haven’t invited him since his wedding!”

Applejack squinted. “And what about before he was married?”

Rarity kept a tight-lipped poker face, but Fluttershy – still blushing hotly – gave a slight nod.

The revelation of her brother’s involvement sent Applejack into a fuming, stomping fit around the throne room. She kept counting to ten for some reason.

But Twilight took the opportunity to speak to Rarity before Applejack got over the shock. “Um... Do you think I could come along next week?”

Rarity leaned in close. “I don’t know why we’d need to wait a whole week.” She glanced over at Applejack. “In fact, I think I would much rather be there right now, if you catch my meaning.”

Twilight smiled. “I’ll distract Applejack. You get Fluttershy and your favorite stallion friend, then meet me at the spa.” She was already thinking about future visits and a certain very close friend of her own she might like to invite to their next spa day...
