At her Desire's Mercy

Luna awoke with a start and a headache. The buzzing of the crystal walls around her matched what she felt inside her head, and already her memories of the dream were growing muddy. There was one thing she could remember clearly: Shining's eyes staring straight into her soul. She could still feel a burning sensation within her where his gaze had seemed to focus on. Everything else was a blur of sex and pleasure.

She stood up, and in doing so realised her thighs had grown wet, her underwear drenched. With a scoff, she lit her horn and dried herself, although it didn't totally get rid of the smell or the tingling sensation in her nethers. No time to waste. Spike was somewhere in the castle, and she had to go looking for him if she wanted to get any information about what was going on.

She checked a few more rooms. Not all of them reeked of sex, but most did. It became even more clear in her search that a lot of ponies had been living there at some point, just before the place had suddenly and mysteriously grown empty. Maybe they were all just part of Twilight's staff, but their disappearance was still concerning. After a while, she ran into the doors leading to what she remembered being Twilight's throne room, if it could be called that, and she stepped in to have a look.

Immediately she noticed something was different. The multiple thrones that had originally encircled the central map of Equestria were gone, replaced with a much larger one standing tall in front of it, the map effectively rendered a hoofstool for whoever sat on it. And right on top of it, lying asleep before the throne, was Spike. She immediately rushed towards him, but she flinched and slowed down when she heard him moaning in his sleep, still enjoying his dream. He was less tall and well built than he'd been at the start of the dream, but he'd grown since last she'd seen him. Definitely a proper adult by age at this point. She wondered if maybe his recent coming of age was the source of his apparent insecurities.

As she got on top of the map to have a closer look at him, she noticed a letter clutched in his hands. She could see hints of the writing on it, but couldn't make out the words. Trying to pry it from his grasp didn't work, as his hold was as firm as a dragon's could be, and she did not want to risk tearing apart what could be her only solid clue. She knew she should wake Spike and talk to him, but she hesitated, anticipating the awkward conversation that might ensue as a result of his dream. Instead she had a proper look around.

The room smelled of sex rather strongly, but less so than others, if probably just because it was bigger. Nothing else looked out of place aside from the throne itself, until she looked up towards the ceiling. Immediately, it became apparent that the plant-like roots had been entirely covered in glowing blue crystal. The numerous mementos of Twilight's life with her friends were gone as well, replaced with something else. Before she had a chance to get a proper look, however, Luna was distracted by the clear sound of approaching hoofsteps.

She tensed up, but relaxed when she saw who walked in. Starlight Glimmer greeted Luna with a smile. She was fully naked, her large breasts and wet pussy bare for all to see. "I was waiting for you, Luna. I'm glad you have made it." Then, stepping closer to the table, she looked at Spike, a strange glint in her eyes. "We should let him rest. The privilege of keeping our King's palace clean and organised as we wait for his return is a taxing one; he's earned his dreams."

Luna blinked in confusion, though she could not place the source of her puzzlement. Every time she tried, she just came up blank. It was like trying to walk out of a room and ending up right back inside. "What do you mean? Your King? Who is he? What is going on here? We were sent to find Princess Twilight and the rest of the Elements and we have been unable to locate them. What has happened?" The notion of a King briefly made her ponder if Sombra wasn't the one behind everything, but nothing of what she'd seen seemed like his style. Crystals, sure, but his were always black.

"King Shining Armor," Starlight replied in a dreamy, reverent tone. "He's the one who showed us the true way things are meant to be. He brought us happiness. He waits for you in the Empire now, and I know once you've spoken to him, you'll come to agree with him. I'm here to lead you to him."

Luna blinked again. So Shining was the one behind everything, or perhaps he was possessed by the true source of the disappearances? Knowing him it made little sense he would be wilfully involved in anything like that, so maybe he really was possessed by Sombra, or a changeling had taken his place. Regardless, he or whoever for him did not seem to be acting in an overtly hostile manner, so perhaps a diplomatic approach would be the best one. She did not wish to harm anypony, especially not him, and without the Elements her options were limited. Still, she had to make sure everything really was okay. "What about Princess Twilight and her friends? Are they safe?"

"They are with him now." Starlight's expression was a mix of wonder and envy. "They are happy, and you will be too once you have joined them. Shall I lead the way?"

Luna was still struggling to get her thoughts in line. Something was nagging at her, but she couldn't place it. Half-heartedly, she gave a nod. "Yes, please, do lead the way. I will much like to talk with your King, and inquire about the matters at hand."

"Wonderful." Starlight turned and began to head out of the castle, swaying her hips and wagging her tail as she walked. As they made their way back towards the train station, they were slowly joined by a small group of mares in various states of undress. Luna spotted eight in total, two ponies of each tribe plus a zebra and a griffon. In particular, she was pretty sure she recognised one of the pegasi as a member of the Wonderbolts. She was about to approach them, but was first approached herself by one of the earth ponies, a middle-aged pink mare with a purple mane and an odd-looking nose.

"A Princess as well, huh?" she said haughtily. Then, turning towards Starlight and nodding towards her own scant clothing, she asked, "Is this indecency really necessary?" Oddly enough, she was unarguably the most dressed out of them all, Luna aside.

Starlight chuckled and spoke to Luna instead. "The King will have a lot of fun with her." Just then, she was approached by the two pegasi, who looked strangely lost.

"We're going to see Dash, right?" the first asked, and Luna finally remembered her name was Spitfire. The other pegasus was likely a Wonderbolt too, judging by what tatters of her uniform she still wore over her light-blue coat and by the way her white mane was styled.

Starlight nodded in reassurance. "Yep." She then turned and called the griffon, a young-looking chick with a mailbag slung over her shoulder, who was lagging behind and looking at a letter in her hands. "Gabby, I already told you someone else will take care of that. Please come along."

Gabby hesitated, blinking slowly, then let the letter and bag both fall to the ground and joined back up with the group.

Starlight smirked as she once more led the way forward. Still speaking to Luna, she explained, "She wasn't originally part of the list, but when I saw her I knew I had to take her along. Griffons are a rare catch after all."

Luna blinked a couple of times in confusion. "I'm sorry, what exactly is the reason they're coming along?"

"Oh, right, I didn't tell you. Silly me." Starlight chuckled. "You see, King Shining Armor keeps tabs on the mares living in his cities, and occasionally he'll pick a few of them and send one of us to fetch them for him. I'm actually kind of jealous." She nodded towards the group. "I wish I could get to experience my first time with him again. I just know they will be so happy with him. And so will you."

Luna did not have time to dwell on that, for at that moment they walked into the train station. Their ride was already waiting for them. Luna was pretty sure the name Crystal Express had always been meant to just indicate the train's destination, but up close it was clear there were actual pieces of glowing crystal making up chunks of the structure. She was distracted from that by the sound of Starlight's voice.

"...Fleetfoot, Sugar Belle, Zecora... Yep, that's all of you. Come along now." She nodded towards the train's open door, and waited beside it to make sure everyone got on board. Luna was one of the first to do so, and quickly found herself a nice, comfortable seat. From the inside, the way crystal seemed to have enveloped portions of the train was even more evident, as was the buzzing sound coming from it. She doubted that would be a concern once they were moving, for the sounds of the train itself would surely cover it.

Once the last pony had boarded, Starlight closed the door, then walked towards the front end of the train. A short bit later, they began to move, leaving Ponyville behind. Luna watched it go from the window. Starlight came back after a bit. The train was strangely empty, just the ten of them as far as Luna had seen.

"Alright, girls," spoke Starlight, addressing all of them. "The train is on its way, everything is in order, and we should be arriving in a few hours. Feel free to relax during the trip, and if you need anything don't hesitate to come to me." She gave a cheerful smile, and then found herself a seat.

Luna figured she didn't need anything, as the persistent sense of something being amiss failed to resolve into anything concrete. Since she knew the trip would take a while, and she had nothing better to do, she figured it was worth trying to head into the dreaming again in search of Twilight and her friends. She did not completely trust Starlight, as friendly as she was, and there was always a chance that so far she'd missed the Element Bearers because they'd been sleeping at odd hours. Lulled into relaxation by Starlight's soft moans, Luna closed her eyes, and once more opened them to the world of dreams.

Dreams work in funny ways. Distance and position are more like suggestions, and what is close or far in the real world seldom means much to what is in the realms of unconsciousness. In Luna's case, the fact that she was travelling towards the Empire, and the fact that she was focused on that fact, meant her dreamworld position was projected ahead, already in the midst of those living within the crystal city.

Or, at least, she was pretty sure that was the case. The dreams around her did look like those of crystal ponies. But she could not see clearly within them from outside. She could not see anything around her clearly, truth be told. It was as if the entire dreamspace was immersed in something thicker than water. It had the consistency of molasses, and just about the same taste. It slowed her movements, and slowed her thoughts, those being one and the same in the world of dreams.

As she looked around in confusion, if not yet worry, something caught her attention. A brighter light than anything she'd ever seen in a dream, a strange and unprecedented phenomenon she struggled to make heads or tails of for a moment. Three different, separate dreams seemed to have fused together into a single, shared entity. Shared dreams were not unheard of, but they existed only by her hand. A naturally occurring one was extraordinary, and the possibility that someone else had caused it was dreadfully worrying. She swam closer, curious.

Her curiosity grew exponentially once she was close enough to distinguish who the dream belonged to. While still blurred, there was no mistaking that Rarity, Applejack, and Rainbow Dash were the three ponies whose dreams had been welded together. Swimming faster, beating her wings and reaching out with her hand, Luna made the last stretch of the way and finally touched the surface of the dream. It sucked her in, but she was prepared, and her landing was graceful.

The scene around her was familiar. Roughly the same throne room as Spike's dream, if subtly different in the way memories and fantasies of the same place are never the same, much less across different ponies. Shining was there again on his throne, though he looked largely the same, sculpted physique and massive cock and all. He was still almost completely naked, although this time he did wear a series of somewhat extravagant ornaments on his shaft, made of gold and six unusually large, different-coloured gems.

She focused instead on the three dreamers, finding them a short distance from the throne, and just as naked as Shining was. Luna was no expert on how ponies looked, always used to seeing the mutable appearances they took within dreams, but she could not help think that the three seemed a decent bit more sexualised than last she'd seen them. Applejack's butt was unnaturally round, and Rarity's tits definitely weren't that big last time she'd spoken with the unicorn. Rainbow Dash was still as small-breasted as ever, though. She chalked it up to how they imagined themselves in a sexual kind of dream, and shifted her focus to who else was there.

The three mares were joined by their three younger sisters, even if in Rainbow Dash's case the bond wasn't born of blood. Only, it obviously couldn't really be the three fillies, as their naked bodies were far older than they should have been in the real world. They had to be projections of the dream, imagined versions of the three fillies grown up. And my, how they had grown. If Luna was to judge them honestly, each one outshone her older sibling in terms of beauty, at least as far as her tastes were concerned.

The three older mares, with blissful smiles on their faces and a glow in their eyes, seemed to be urging the younger ones towards the throne. It looked almost like an offer, befitting the worshipful aura that permeated the scene. Apple Bloom stepped forth first. Her body was a match of her sister's, hardened and sculpted by a life of hard work but still rather sexy, sporting sizeable breasts and a rather large ass. She had perhaps a bit more fat to her than Applejack, but Luna had to admit she liked that about her. She knelt before the throne, and spoke. "I offer my body to you, my King. May my fertile hips bear as many of your children as you will wish to bless me with."

King Shining openly smiled at that, his huge cock throbbed lewdly, and he nodded along. Sweetie Belle came next, urged on by Rarity. Her soft white body was supple in all the right places, and what thickness showed on her stomach was more than made up by what else she had to offer. Her thighs were meaty and her ass was as nice as Rarity's, but her tits were the real stars of the show, fat and heavy and wobbling with her steps. She kneeled beside Apple Bloom with a reverent, elaborate bow, and spoke to her King. "I offer my body to you, my King. May my soft and ample curves delight you and bring pleasure to your divine cock, as you deserve to experience."

Again, the King looked pleased, and he nodded for the next one with his head as much as with his shaft. Scootaloo was next, and she briskly trotted forward, helped along with a spank to her behind by Rainbow Dash. She looked like the older pegasus in many ways, lithe and muscled and flat as a board, but her ass was something to behold. It was large and perfectly round, and attached to a pair of hips that matched even Applejack's. She didn't kneel as the other two had as she spoke, and her tone was far more casual than theirs. "I can take a bit of punishment, my King. In fact, I like it rough. Feel free to fuck me as hard as you want and take out any frustrations you might have on me."

Shining looked just a little bit bothered by her behaviour, though his look of mild annoyance seemed directed more at Rainbow Dash than at Scootaloo. Still, his shaft did throb with desire at the sight of the lithe pegasus offering herself up for him to use, and in the end his expression melted back into a happy, if sinister smile. He licked his lips, then finally spoke, and again Luna had the impression that his voice could not possibly belong to a mere mortal pony. "I accept your offers, and welcome you as my slaves. You may begin to serve your King, as is your right and duty and destiny."

Things moved in a blur, in the way things move and happen within dreams. Shining was fucking the three young mares, pounding into each of them and all of them, without rhyme or reason between what he did one moment and what he was doing the next yet with a constant, encompassing theme all throughout. He was not merely fucking them. He was dominating them, completely and utterly, their bodies submitting entirely to his strength. Their minds were not far behind, as they moaned and howled in pleasure while he used them for his own. Slaves had been the right term, for no stallion would ever treat a free pony that way, and no mare who could consider herself free would ever rejoice so completely at being used like that.

Scootaloo got every bit of the rough treatment she'd asked for. Pressed against a wall with her knees hooked over Shining's shoulders, she let her tongue loll out the side of her mouth as he hammered himself into her, reddening her fat ass with the strength of his hips crashing into it. Her flat chest slid against the floor as Shining pounded her rear, spreading her backdoor wide with his cock. "Take it, bitch!" he hissed. Tears from her puffy red eyes streaked her cheeks as he slammed her throat into his cock and then pulled her back over and over. Luna's breath caught in her throat. She vanished her panties in a flash of magic, then the rest of her clothes as well. With one hand up her cunt and one twisting her nipples, she watched the scene unfold before her with utmost attention.

Apple Bloom had her wish more than granted as Shining unloaded a flood of cum bigger than every orgasm Luna had ever witnessed combined into the depths of her pussy, the outline of his cock visible in her belly before disappearing within the bulge of her cum-stuffed womb. "This is what you wanted, you whore!" he barked, slapping her fat tits and causing milk to leak out of them as he bounced her on his lap and stretched her suddenly empty insides with his cock, just to flood it again a moment later. Cum coated her mane as she jerked him off with both hands, before he hit the side of her head with his shaft. Luna was on her knees, fingers moving faster as her thumb circled around her clit.

Shining's cock slid between Sweetie's fat tits, and she purred, licking the tip when it moved close enough to her mouth. "You like this, don't you, you slut?" he mocked her, pulling roughly on her mane as he hilted in her ass, fat balls slapping against her pussy and making it spray arousal all over them. Her voice sang her pleasure in heavenly tones as he spread her nethers with his strong, thick fingers while resting his nuts over her eyes, filling her vision and lungs with his virility. Luna's mouth silently mouthed a yes, as image after image of Shining's utter domination over the three young mares flashed before her eyes.

King Shining nodded towards his other three slaves. Gleefully they joined in the depravity, aiding their younger siblings in pleasuring their Master. Shining's tongue wrestled Scootaloo's into submission within her mouth as he pistoned in and out of Rainbow's pussy, while the younger pegasus kept her fat ass pressed over her sister's face. His dick left Sweetie's ass and plunged into Rarity's mouth while the former lapped at the latter's pussy. "This is all you're good for!" he growled as he forced both Applejack and Apple Bloom to slurp on the sides of his cock while his magic spread their pussies wide. And Luna nodded, feeling her heart beat faster and faster, her skin growing hotter as her own marehood spilled her arousal to the crystal floor.

Shining had his cock deep in one of the three mares while fingering the other two at her sides, and all six mares were in all three positions. "Weakling," he commented as he easily held Apple Bloom's back against his chest, stretching her muscled belly with his cock as Applejack lapped at his balls from behind, and Luna moaned. "You're the one who asked for this!" he said as he groped Rarity's tits with one hand and her ass with the other, while forcing Sweetie Belle to eat his cum out of her sister's pussy and stretching her own with his shaft. Luna felt her head spin and she could only repeat the same yes, over and over. "This is why you came here," he grunted as his cock thrust between Scootaloo's and Rainbow's asses, while his fingers thrust into their mouths. Luna breathed faster and faster, so close to the edge. "You know this is what you deserve, don't you?"

Luna blinked, suddenly shocked by the way the words had sounded so clear in her ears. The flashing images before her crystallised into a single one. Shining, standing tall and imposing before her as his slaves dutifully worshipped his cock and his muscled body, staring straight at her. He spoke again, and he was talking to her. "Do you understand the price of the pleasure you crave?" Luna felt frozen, pinned on the spot. Dreams were supposed to be her domain, and yet she felt completely trapped, all control taken away. Shining was the one in control. An indescribable shiver raced down her spine. Her lips quivered as her mouth opened, to scream or to answer she didn't know.

Then the whole world lurched forwards, and Luna's eyes snapped open as the train came to a stop within the Crystal Empire's train station. "We're here!" Starlight called cheerfully as she stood, nipples stiff and thighs wet. Her voice was met with a chorus of pleased sounds and moans from the rest of the carriage. Luna groggily blinked herself fully awake, feeling like she was waking up after a night of heavy drinking.
