At her Brother's Command

Twilight awoke to a strange sound coming from the next room over. It was wet, squelching, maybe a bit like water going down a clogged pipe. In her half-asleep state she listened to it until it stopped, then slowly shook herself properly awake. She'd slept in a little. Her dreams had left her sweaty and warm. She'd stayed up reading until she'd passed out the night before, and while she'd been tired enough for that to happen quickly it had still been fairly late.

The book wasn't quite what she'd been expecting, but it was intriguing. She wanted to keep going. Not then though, maybe that night. She pushed herself up and stretched her arms and wings, yawning as she opened the window with her magic to let the sunlight in. Groggily she stood up and made her way to the bathroom, wearing only a loose-fitting T-shirt. It wasn't like anyone would see anything. Perks of being a Princess included a private bathroom, and getting to decide when she'd have breakfast late.

She arrived downstairs in the kitchen a few minutes later, dressed properly and with her mane straightened out. Cadance and Shining were already there, dressed casually like how they'd arrived the day before. "Hey," she greeted them. "Sorry, I woke up late. I must have been tired yesterday." She went towards the stove and opened the cupboards above it. "How did you two sleep? Do you want something?"

"We already ate." Cadance licked her lips.

"We slept well, thank you for asking," Shining said. "Do you know where Starlight is? Sunny gave us a thing for her. We looked around a bit but we didn't see her."

Twilight had begun to make herself a pancake. Being a Princess meant she could decide what to eat too. It also meant she wouldn't get fat from it, something Rarity never failed to bemoan her jealousy of. "I think she's leaving us be. You know, family time and all. She's probably in the laboratory or somewhere around. I can have Sp-... I can go look for her and tell her to come see you later."

"That would be lovely." As Twilight was still turned, Cadance reached out with a hand and rested it between Shining's muscled legs. "Did you have something planned for today?"

"Not really. I didn't have time to really plan anything, unfortunately." Twilight was still focused on her pancake. Spike always made it seem so easy. Was it getting burnt? "But I figured we could just hang out, chat, maybe play some games. You know, casual stuff. I didn't think I'd ever say it, but I've had enough of checklists for the time being. I could do without all this princessy business for a while."

"We can certainly help with that," said Shining. "Say, did you start reading that book we got you? It's one of Cadance's favourites, and she's been dying to know what you think." As he said that, he wrapped an arm around Cadance's bust and groped her tits in an entirely inappropriate way.

Twilight stammered and blushed a little, standing straighter. "I've read a bit of it." She slid the pancake onto her plate. Definitely a little burnt. "It's... interesting. Yeah. I can see why she likes it." She just wasn't sure if it made for a good present yet.

Since Twilight was still turned, Cadance began to stroke her hand down the length of Shining's thigh, and what else was there. "Just wait and see. You'll understand soon."

"I do look forward to reading the rest. Probably later today." Twilight turned and found Cadance and Shining wrapped in a deep kiss. "Oh, you two." She sat down at the table. "Do you ever tone that down?"

Shining broke the kiss. "You'd be surprised. This is already toned down." He gave Cadance another quick peck on the cheek.

"I'm not the Princess of Love for nothing," Cadance added, nuzzling into Shining's shoulder.

Twilight dug greedily into her breakfast. "I suppose." Being a Princess did not mean she could ignore etiquette and speak with her mouth full, but she did it anyway. But she did swallow before continuing. "So, how are things in the Empire nowadays?"

"Wonderful," Cadance said, beaming. "Shining and I have enacted and implemented a few new policies, and our subjects absolutely love the way things are going."

Twilight swallowed another bite. "I'm honestly glad I don't have to do anything like that. I can't imagine having to decide things for so many other ponies. I don't know how Celestia has managed to do it for so long."

"Some of us are more fit for it than others," Shining said. "But I'm sure Celestia would like to take a break from time to time, too. We should invite her to the Empire on vacation at some point."

Cadance was positively radiant at that. "We really should."

"But now we should focus on Twilight," Shining reminded her.

Twilight blushed. "This isn't just about me. It's about all of us." She looked at them and smiled. "I've missed you two." They smiled back at her, and she looked down at her empty plate. "Well, I'll go find Starlight first, and then we can see about the rest of the day." She stood up.

"The gift is in our room. Tell her to come there," Shining said.

Twilight nodded. "Be right back. Don't chew each other out too much while I'm gone." She walked to the door and left the room, oblivious to the way Cadance slowly slid off her chair and reached for the hem of Shining's pants as she did.

Starlight scratched at her horn. Something was bothering her. She'd been just about to run a proper test, but Twilight had called her before she could start. She wondered if it was the castle acting up in some way. Ambient magic wasn't unheard of, and it was even expected in a place like that, but she wasn't so sure. Whatever it was it felt different. The possibility of someone attacking the castle while both Twilight and Cadance were there was entirely real, even if she may have been a touch too paranoid about it.

She shook her head. That could wait. She stood in front of the door to the guestroom, hesitant. Sunny had sent something for her, apparently. She swallowed. She hadn't heard from her friend since... Well, since the news of her name change, and all that went with it. Starlight was happy for her, of course she was, but she was also worried. She always worried. It was why she'd been avoiding Shining and Cadance. Maybe she should stop worrying so much.

She reached out, and knocked on the door. For a moment nothing happened. Then the door slid open. The room behind it looked a little dark, like the window and blinds were closed, but also lit by a strange light. A magical one, perhaps. Blinking, curious, Starlight took a step forward. Then stars exploded in her vision and she passed out.

Twilight was back in the kitchen. There was a leftover piece of doughnut Cadance hadn't finished, glazed white and a little soggy. She'd told herself she'd be cleaning the table after sending Starlight to the guestroom, but hadn't gotten around to it yet. Part of it was just laziness, but she was also distracted. She'd gone and picked up the book from her nightstand, and it was lying before her besides the plate. She was looking at it. She wasn't opening it yet. She wanted to, and at the same time she was nervous about it. She wasn't sure her memories of the previous night were accurate, but the possibility that they could be was making her heart beat fast and her cheeks flush. She absentmindedly took the doughnut chunk in her mouth. It tasted a little odd, but good.

The air in the room felt hot and stuffy, and it smelled weird. She got up and went to the window, and looked to the sky outside as she opened it. There were a few stray clouds, thin and white. She wondered how Rainbow Dash was doing. She should have Rainbow Dash come over. Rainbow Dash might enjoy talking with Shining.

Twilight shook her head. She felt like she'd dozed off for a moment. She looked back to the table. Right. Her book. Taking a deep breath of the fresh morning air and enjoying the little breeze coming in from outside, she grabbed the old tome in her telekinesis and opened it again. She scanned over the page and her breath grew hot and heavy, memories of the previous night coming into clear focus. It was scandalous. Completely inappropriate. But she couldn't turn away.

She read on avidly as the Warrior Queen went to strike the King of the Wildlands with her blade, only for him to easily catch her arm at the wrist and halt her blow. The author had spared no lurid detail in describing how the Queen's clothes barely contained her huge chest, how her fat tits bounced with her motions, or how the King's chiseled abs glistened with sweat as he overpowered the mare and forced her first to drop her weapon, then to bend down to her knees before him. Eye level with the scant covering hanging over his crotch. Close enough to smell his-

Twilight turned away and slammed the book shut. She was breathing heavily, feeling heated up despite being right next to the window. It was then she properly realised anyone outside would be able to see her clearly, and a different kind of blush came to her cheeks. Her first instinct was to scamper off, but something held her. She looked back to the book. It had been a present, after all. And surely Cadance and Shining would tell her when they were done chatting with Starlight.

Slowly, carefully, Twilight sank down to sit on the ground beneath the window, with her back against the wall and even the tip of her horn hidden from view. She shivered for a moment, then forced herself to open the book again and continue reading. The Queen had tried to strike with her free hand, but again the King had caught her, and he'd pushed her to the ground on her back. He had her pinned down there, as the amulet hanging from his neck dangled right before her eyes. Twilight took a deep, hot, shaking breath. Cleaning the table could wait another minute or two.

Starlight's eyes blinked themselves open once, twice, three times, then finally her vision came into focus. She was in the guestroom, that much she could tell even in the strange blueish glow that filled the otherwise dark room. What she could also tell, despite not being able to see it, was that she was tied to a wall with her hooves spread slightly apart and her arms bent, her wrists level with her head. She was gagged too, judging by the stuffy feeling in her mouth. She tried to use her magic, and found it blocked, just as she'd expected. She wondered if it was a ring or a suppression circle, or something else.

She was prepared to see changelings before her, or cultists, or any other manner of villainous thing. She was not prepared for Shining to step into view while holding a collared Cadance up by her legs, her knees against his shoulder and her back against his chest, with his cock deep in her ass while her pussy gushed out over his fat balls and her mouth did the same over her pierced tits. That was deeply wrong, and entirely inappropriate for any evildoer. She would have known.

Shining noticed she was awake first, since Cadance didn't look capable of noticing anything in her state. "Ah, Starlight. I see you're finally awake." He dropped Cadance, but made sure to catch her with his magic so her swollen belly wouldn't hit the floor. Slowly he pulled back from her stretched asshole, revealing a thick cock that was longer than Starlight would have anticipated, and as his wife shook herself back to some semblance of mental coherence he stepped closer to the wall. "You know, we could have done this while you were passed out. But where's the fun in that?" He slapped Starlight's face, hard, but in doing so removed her gag as well.

Starlight resisted the urge to retch at realising she'd had her mouth stuffed with a pair of boxers, and instead threw Shining a piercing glare. "What's this about? Who are you?"

Shining just slapped her on the other side of the face in response, chuckling. That did, however, push Starlight's gaze to land on a large chunk of crystal lying on a desk, the source of the eerie blue light that filled the room. Shining spoke again. "You're smart, for a mare at least. I'm sure you can figure it out."

Starlight slowly turned back to him. Right then, she noticed a strange ethereal strand between his horn and Cadance's, but ignored it for the time being. "A catalyst for a continuous spell, resonating with the castle itself to affect the whole interior. So that's what I was feeling."

Shining laughed, and turned to Cadance. "See? I told you we were right to start with her."

Cadance leaned into Shining to caress and lick his naked chest, then turned to Starlight. "Do you know what kind of spell it is, too?"

Starlight swallowed. There was something off about Cadance's eyes, but it was hard to see. "I know you cast it, based on the colour." Her brain worked overtime to try and figure out what the fuck was happening, adrenaline suddenly kicking in. What Shining and Cadance were doing made no sense, if it even was them, but the aura meant it was the real Cadance, and... Wait. "Mind alteration." She began to think aloud. "But it wasn't targeted at me, I wouldn't have felt it otherwise. So that means..." Her eyes went wide. "Twilight."

"Bingo," Shining said. "Or close enough, at least." He went and pinched one of Cadance's nipples.

"It's a perception filter," Cadance explained. "Subtle, continuous, and pervasive. It's slowly filing down her thoughts as we speak, and it'll keep doing so until all it takes is a little push."

"But why?" Starlight's mind still failed to come up with an explanation for their actions, or to even understand what exactly they were doing. "What do you want? What has your sister done?" If he even was the real Shining.

He gave something between a grunt and a laugh. His horn glowed for a moment. The connection between it and Cadance's grew brighter, and Cadance wailed in pleasure as magic visibly flowed out of her and into him. "Twilight is an alicorn," he explained. "That makes her worth keeping as part of my harem. It makes her worth breeding. It makes her power worth consuming. By the rightful order of things, she's meant to be mine."

Starlight started to hyperventilate, eyes darting between Shining's feral expression and Cadance's quivering body. "You're insane. You're fucking mad. I don't know what the fuck has gotten into you to go after your sister like that, or, or to do any of this, or..." Her words stopped coming and she just kept breathing, overwhelmed by the situation as her worry and anxiety spiked.

Shining ignored her, and reduced the drain on Cadance's magic back to a barely visible level. "But Twilight is an alicorn, and an Element. She's smart. Her magic is great." It looked like what he was saying was making him actively angry. "She may resist if we simply try to overpower her, and even if we succeeded the Elements might intervene." He advanced on Starlight, and his expression shifted to something more pleased. "So we're going to wear her down, slowly, and take care of the Elements and any other problems along the way. Starting with you. Not that you were ever going to be a challenge, but the others don't stand a chance once you're down." He grabbed her blouse and tore it apart, baring her chest, then ripped off her bra.

Starlight began to thrash in her bonds, trying desperately to break free, pulling on her magic reservoirs with all her might in the vain hope of overpowering the suppression. "You're insane! You're never going to succeed! The Elements will stop you! The Princesses will-"

"The Princesses won't be able to do shit once Twilight's power is mine." Shining slapped her tits hard, then drew back. "Insane? I am a God. And as for you, well..." He chuckled. "We can't risk trying to use brute force against Twilight, but you? You're no match for an alicorn."

Only then did Starlight notice Cadance's face just besides her own, horn aglow. She tried to scream, but her lips were sealed by a kiss from the alicorn's own, the salty taste of Shining's sweat and virility invading her mouth alongside Cadance's tongue. Starlight only had a moment to notice the faintly glowing heart shapes within Cadance's eyes, then her psyche was split open and her mind was flooded with alien memories of pleasure and submission.

The table was still messy. Twilight's clothes were too. She hadn't taken them off, but she'd done some rubbing through them, and some even beneath them. She'd had to stop before she got carried away too far and started being louder than the whimpers she'd already been letting out. The book lay beside her, still open, a decent amount of pages deeper in. The mental images it had conjured hung in her head, but she shook herself and forced her breath to slow. It was not the right time. Cadance and Shining could be back at any moment.

"Hey, Twilight!"

Twilight jumped up at that, wings spread, a very unprincesslike squeal leaving her throat. She turned towards the window, where the voice had come from. "Rainbow?"

Rainbow Dash was there, hovering in the air with her back towards the ground and her head looking upside down at Twilight. Her legs were still outside, but everything past her waist was inside the building, displaying her complete lack of understanding of privacy and personal space. "Yeah. I came by, like you asked me to." She rolled onto a prone position in the air, and the golden necklace wrapped around her neck with the red lighting bolt jewel embedded in it became clear to see. "What were you doing on the floor?"

Twilight had several questions, not last of which how Rainbow managed to consistently display worse manners than even ponies who had actually been raised in a barn, but at Rainbow's question and seeing the pegasus look down something more akin to survival instinct took over. She quickly shut the book with her magic and pulled it back behind herself. "Oh, you know. Just some boring studying you wouldn't like." She awkwardly cleared her throat, and tried to calm down. "Shining and Cadance are having a chat with Starlight, and I was waiting for them."

Rainbow fully pulled herself in, and touched down on the floor. "Speaking of. You said he wanted to see me, yeah? Sorry, it took me a bit to tell everyone and go grab mine. Which way to their room?" She began to head past Twilight without waiting for a response. "I'm supposed to meet up with Spitfire later and I might have to help with weather duty after that, I don't have much time."

Twilight watched Rainbow walk out of the room, still confused. Only after her friend had disappeared past the corner did she remember to answer her question. "They're in the guestroom. Right next to my room."

"Thanks." Rainbow's voice grew distant, and was barely audible as she asked, "Why do they want to see the Elements anyway?" Her steps picked up speed, then were replaced by the sound of her beating wings. Twilight put a hand to her head. Something felt wrong, but for whatever reason trying to pinpoint what just resulted in her getting a headache. It was like someone had spilled ink about halfway down her mental list of things, and looking at it hurt.

So she looked to the sky outside instead, to clear her thoughts. Then she blinked, and looked again. Was the Sun really on the other side already?

Dash blinked. Her head felt foggy, like she was halfway through a night of heavy drinking. She felt hot and sweaty like after a training session, and she felt good. The room was dark, barely lit by a strange light blue glow that seemed to buzz in her vision like it was trying to burrow its way into her brain. She felt good. There were sounds in the room, unfocused and hard to tell apart. She tried to concentrate on them. One kind stood out among the rest. Moans.

Her eyes snapped fully open, colours and shapes coming into focus in front of her with more clear definition. On the bed, Starlight was on her knees, her chest pressed low onto the crumpled messy sheets. Her tongue was lolling out and her eyes were rolled halfway back into her head. She was moaning from deep within her throat, and her body shook powerfully at a fast, brutal pace. Rainbow looked a bit past her and saw Shining kneeling behind her, forcing his hips against her own over and over as he held her tail with one hand. His chest was bare, but a hint of gold and red shone on his neck, bouncing along with his motions.

Rainbow was naked too. One of her hands shot to her neck, feeling her bare skin. Something felt wrong. She had to focus on something, but she couldn't remember what. Her thoughts were being smothered by a thick weight and thinking was like trying to move through honey with weights on. She tried. She squinted her eyes, breathing deeply in an attempt to understand what her mind wanted to tell her. Then a spike of pleasure drove through her, and her thoughts shattered again. She arched her back and moaned, suddenly aware of how sensitive her cunt was and of the tongue probing into it.

She looked down to see Cadance bent down onto her crotch, lapping expertly at her pussy while her hands held Rainbow's toned thighs spread apart. Her horn was glowing the same blue as the colour filling the room. It was so pretty. Rainbow watched the point of light bob up and down, losing any interest in anything else. It felt so good. She was starting to remember. She thrust her hips upwards to meet Cadance's mouth.

Shining and Cadance had invited her in for a threesome. Or was it a foursome? Her eyes went to Starlight's completely cockdrunk expression for a moment, then right back to Cadance's horn. Didn't matter. The details didn't matter. The pleasure did. She brought a hand to her small tits to pinch her nipples. She'd agreed, of course. She wasn't about to pass up a chance to score with an alicorn. And Shining... She wasn't into stallions, but she... She wasn't... Shining... Shining's cock... The glow of Cadance's magic filled her vision. Image after image of Shining's thick, long, absolutely amazing cock flashed before her mind. Rainbow growled, and came all over Cadance's face.

Twilight sat in bed. On top of the covers, but with her windows closed. That was why it was so hot. Yes. She couldn't open the window, though. Ponies outside might hear. They might see. She moaned quietly, bucking her hips into her hand, as the book quivered in the air within her magical grip.

She hadn't seen Rainbow leave. She hadn't seen Starlight again. That was okay. She'd seen Shining again at dinner, and everything was okay. Starlight was probably back to her experiments, and Rainbow had other things to do; surely she'd gone straight away after meeting with Shining. Twilight's eyes raced over a line after the other, drinking in the contents of the book like water after a trek through the desert. There were sounds coming from Shining's room. Slaps. Moans.

That was okay. It was okay that her brother had only been with her a little before rushing to his room, where Cadance waited for him. There was nothing wrong with couples enjoying themselves, even during a pregnancy, especially on a vacation away from responsibilities. She trusted them to be careful. More importantly, at that moment she couldn't give a fuck. Her middle finger wiggled, buried within her cunt, as her palm ground against her clit. She was so close. Just an orgasm and then she would go to sleep. Just to relieve the tension she felt. Just a little more.

The sounds coming from the guestroom, the sounds of her own moaning and laboured breathing, everything faded as she focused her attention wholly on the book. The King had his newest conquest, a haughty sorceress convinced she could best him and overtake his mind, bent down beneath him on the throne room's floor.

He was pounding into her. Hammering his fat cock into her wet cunt as his hand held her head down against the cold floor. Every thrust reddening her asscheeks as they were hit by his abs. His swinging balls striking her clit hard with every motion. Utterly overwhelming her mind with his sheer virile strength until Twilight shrieked and arched her back and came, stars exploding in her vision. The book fell from her magical grip and she lay panting and dizzy in the dark, listening to the moans and wet slurping sounds coming in from the other room.
