Chapter 18: Friendly Conversation

With Cadance gone, a familiar unease returned to the dining room. An awkward tension that seemed to silence every pony in the room and make every noise in the room seem so much louder. It was difficult to explain exactly why such an awkwardness had befallen the room, if not for the fact that Umbra knew that it was time to push the poor fool Shining Armor along a bit.

Especially when Twilight had put in so much effort for her new tits.

“So Twilight—" Umbra’s voice was no longer that of a petulant teenager. Her Umbra persona was now beginning to overshadow her Sombra one. She held herself now not like an aloof tyrant but instead like a predator, waiting to strike. Eyes flashing with lust, cruelty, and sinister, sinful schemes. “You simply must tell me about your new bust size. You were so modest before, perhaps a B-cup charitably. But look at you now; I’d have to guess at least a pair of double Ds. Such an improvement.”

“Oh!” Twilight gasped, flushing red. But not out of embarrassment but rather modesty, the sort of modesty one would show when receiving a compliment or praise. “You noticed.”

“It is hard not to.” Umbra said, her blood-red eyes darting quickly to Shining Armor, who had (predictably) just noticed. “You’ve put in some effort into your bust. I’m sure it’s going to help you in your quest. How is that going by the way?”

She acted like a concerned friend, but her eyes were gleaming with such a sinister, sinful light. She could see the warring emotions in Twilight’s eyes, doubting whether to accept this suspiciously open Umbra or to treat her like a dangerous animal.

But Twilight was spared the difficulty of the decision by something far more interesting. Quite simply, the interest of her brother, who had finally truly registered the size of Twilight’s new tits and just how fuckable they were. He was already likely wasting his brainpower trying to purge the naughty incestuous thoughts from his brain.

"Twily, why did you…how did you…why?" He stammered, his once distracted eyes now finally snapping into action and being drawn to Twilight’s bust. Every once in a while, he’d bring them back to Twilight’s eyes. But these flashes of decency were few and far between long periods of simple ogling.

“You like them?” Twilight asked, a bit too excitedly. She was wearing a sweater, but Umbra noticed it was bare around the shoulders and almost certainly a size too small for her. Even beginning to rip in a few key areas. Nevertheless, Umbra could detect the tiniest trace of a purple magic glow around the sweater as Twilight discreetly pulled down her sweater another inch or two in order to reveal more of her new tits. “I got them just for- I mean… it simply seemed appropriate.”

“Appropriate?” Shining Armor gasped, dropping the spoon he’d been using to eat breakfast with. "In what world would something like this be appropriate?"

There was a hint of the typical big brother protectiveness entering his voice; his ears were going red as he started to examine Twilight's bust. Twilight was looking at the floor, her body wiggling slightly. So clearly self-conscious, and yet so clearly aroused. Even as her gaze shifted away from her brother, her bust was pushed towards him. Like it was her newest school project.

"Is that Changeling Magic, Twilight?" Radiant Hope asked, squinting at Twilight's tits. Shining Armor dropped his plate in shock. Radiant Hope had been trained as a healer ever since she got her cutie mark, and her talent was coming in handy here.

"C-changeling magic?" Twilight spluttered, far too quickly to be believable. Umbra almost pitied her, a natural seductress this girl was not. Almost.

"Just from the way they've been inflated." Radiant Hope said, smiling. “You can tell the signs of those things with enough training.”

“C-changeling ma-magic.” A horrified Shining Armor stammered, looking at Twilight like she was about to change into Chrysalis any second now.

“Oh relax, you damn fool. I can assure you that Twilight hasn’t been replaced by Chrysalis.” Umbra snapped at Shining Armor. For some reason he wasn't reassured by this much.

“What makes you so sure? She could be trying to kidnap me again, trying to drain my love again!” Shining Armor said, raising a shaking finger at Twilight. “And how do I know you’re not lying? It wouldn't—"

“If that was Chrysalis.” Umbra snapped, finding the conversation of whether or not Twilight was a changeling quite irksome. “Then I would be smiling. I am not smiling, so get over it.”

“It’s just… I learned that changeling magic would be the best way to alter my body. I really didn’t want to go through surgery.” Twilight explained, desperately relieved that Shining Armor was calming down.

“Why didn’t you tell me first?” Shining Armor said, his shoulders relaxing as he returned to his meal. His eyes struggled to avoid gawking at Twilight’s bust. Umbra could only imagine how he was deluding himself with lies about how he was ‘simply checking for signs of changeling magic’ and other nonsense.

"Well, it was a bit last minute. And I wanted to surprise you.” Twilight admitted, a happy grin returning to her face, seeing Shining Armor's eyes so fixed on her new tits.

“Surprise me?” Shining Armor repeated slowly. The cogs in his brain were finally…finally putting a few of the pieces together. Even if he were far from figuring out the very clear and very, very basic truth standing right before him.

“Yeah, I was thinking of you when I got them.” Twilight admitted shyly. Running her hands over her breasts, caressing them like a trophy. “Do you like them?”

“Like them? Me?” Shining Armor gasped, pointing a finger at himself in surprise. As if trying to confirm if Twilight wasn’t referring to some other Shining Armor.

“Yes, you.” Twilight said, giggling in exasperation. Umbra supposed she found Shining Armor’s naïveté charming in some way.

“Well… I suppose they’re not bad.” Shining Armor mumbled, face going beet red. His hands were clutching the table for support as if he were afraid he might collapse from embarrassment or arousal at any moment. “And well… they do look better than they used to. Especially on you, nice and bouncy.”

As soon as he said those last words, his throat dried up. As if the muscles in his throat had started strangling him. But to the surprise of nobody except Shining Armor himself, Twilight didn’t get offended at all by Shining Armor’s comments. Instead she smiled, and her heart soared, and she cheerfully said. “Thank you, Shining. I really like them myself.”

“It’s an adequate start.” Umbra said, her voice cutting through the nauseatingly sweet and happy atmosphere like a knife through butter. “But alas, they are only a start, Twilight.”

She got up, and in doing so she drew every eye in the room. But she didn’t mind; if anything, she embraced the stares. This was Umbra’s element, the ruthless, deviant dominatrix who kept the slaves of Shining Armor in top shape and wasn’t afraid to speak harsh truths or uncomfortable facts. She marched over to Twilight and gave her tits a firm flick that sent them bouncing.

“They are an ample and solid handful. But that is all Twilight. Quite frankly, they are an insult whether you are an alicorn, a princess, or a sister. These tits need to be bigger than your head, at minimum. A huge gigantic pair of globes that are the first thing anyone will ever notice when they see you. Just like how Celestia’s fat tits are more famous than her sun, your tits must be the first thing anyone knows about you. Everything else about you must be secondary. Whether friends, title, personality, mind, or family relation, it should all be secondary to the size of your tits.”

Umbra had been sure to put particular emphasis on the words ‘family relation,' and from the way Twilight’s eyes widened like saucers, she had noticed too and had realized what Umbra was trying to tell her. If she wanted Shining Armor, she needed to be so sexy and so busty that it would be impossible for Shining Armor to care about ridiculous things like ‘****’ or ‘taboo’ when faced with a sister with such prestigious tits.

“Um Umbra, don’t you think that’s a bit… insane?” Shining Armor asked tentatively. “And you also shouldn’t speak to my sister that way. You look perfect the way you are Twilight.”

He added that last part hastily, almost like he nearly forgot to say it. That or didn’t really want to.

“It does seem to be going a bit far.” Radiant Hope added, tentatively. Umbra had to laugh with the irony that the former cosplaying stripper was worried that Umbra was going too far. But Umbra knew better; she could see it in Twilight's eyes. She wasn't looking at the floor in shame, nor shaking with rage or crying; instead, her finger was tapping her chin, her expression thoughtful, and her eyes glinting with sinful intrigue.

“So, Umbra. How big do you think I should go?” Twilight said shyly, twirling a strand of her indigo hair around her fingers and softly swaying from side to side.

"Hmm…" Umbra put a hand to her chin, circling Twilight in dramatic, sensual strides. No one dared interrupt her as she walked circles around Twilight, blood-red eyes treating her like a piece of marble from which a beautiful statue could be forged. “H-cups, perhaps double HH-cups. It seems more appropriate for a royal. It’s only fitting that a royal of your prestige has an equally prestigious pair of tits. And I think your special somepony would appreciate it.”

There was a loud cough from Twilight's brother, and Umbra lazily turned around to face Shining Armor. “Now really, that is too far. Twilight looks fine the way she is, better now that she has a bit more of a bust, but she shouldn’t push herself. She’s wonderful for her mind, her spirit, and her…her holy fucking boobs!”

The last words had probably not been what Shining Armor had meant to say; rather, they were probably the only words he could comprehend when he looked over Umbra’s shoulder towards Twilight. Umbra smirked to herself and turned around, knowing exactly what she'd find.

Sure enough, she found Twilight casting some more of her studied changeling magic. It was emitted from her horn as a purple flame, in contrast to Chrysalis’s green flames. Her body was altering again, her mane becoming longer and more voluminous and taking on a more glossy texture. Her hips were thinning inwards as her hips and butt expanded outwards. Her fingernails grew longer, as did her eyelashes, while her lips became fuller and shined as if permanently marked with glittering purple lipstick. Her legs grew longer and thicker by a few inches, making her grow to be as tall as Cadance.

But naturally it was her tits that took up the most attention and received the biggest change. Going from a modest pair of double Ds to a humongous pair of double H-cup tits with nipples constantly stiff and the size of grapes. From side to side, her new tits were bigger than a small woman’s torso and would be able to easily smother one in her arms.

The room became silent, Twilight giving a shy, bashful smile, Umbra looking at her in cocky pride, and Radiant Hope’s mouth dropping as her eyes darted between the other three ponies in the room. But the real attention was on Shining Armor’s reaction. He seemed frozen, his mind blacked out; in his eyes, one could practically see the blue screen behind them as he slowly started to reboot his broken mind.

When it finally started to function once more, Shining Armor wasn’t looking at Twilight like she was his sister anymore. It was just like Umbra had predicted; he no longer cared that they were related. He didn’t care that it was taboo. All he could think about were the massive tits that Twilight now had. If only the stupid sweater hadn't been in the way; if only it had ripped in the transformation. But Umbra enjoyed Shining Armor's torment, though there was simply no need to continue the king's anguish any further.

"So, my dear Twilight, have you made your move yet?" Umbra asked, fully aware that the answer would be no. Nevertheless, she waited for Twilight to shake her head, but she was smiling, her body vibrating with lust. She knew what was coming; every fiber of her body knew what was coming and was awaiting it as if it were the moment she had been waiting for all her life. Quite a common reaction among all the women that Umbra had managed to seduce or push into becoming Shining Armor's slaves. "No? Well, I'm sure your new tits will help with the surprise."

She made sure to say the word 'surprise' with as much sexual emphasis as possible, making sure to draw the attention to it. The attention was certainly drawn to the woman, and then to Twilight. Both Radiant Hope and Shining Armor were looking at Twilight, **** to know what this surprise might be. Radiant Hope was smiling, utterly charmed by the sinful creature Twilight was revealing herself to be, while Shining Armor looked at his sister like she was a stranger. A sexy stranger with massive tits that he needed to serve and obey.

His dick was pitching a tent in his pants, a fact that wasn't unnoticed by any of the other three women, who all giggled as they saw it. "It seems Shining Armor is quite interested in your surprise, Twilight; I have to admit I'm very curious as well."

"Su-surprise. "Yeah, I'm quite curious; I admit it," Shining Armor admitted, his voice almost delirious as he spoke. Eyes darting between the three other women like they were goddesses.

"Let's not keep him waiting any longer, Twilight." Umbra said, placing a firm grip on Twilight's shoulder. "I think it's time to show him. So as your queen, I order you to strip."

"What?" Shining Armor gasped, his brain finally functioning properly again. "Right now? Here? She's—she's my sister."

Umbra chuckled darkly. "She is indeed you sister. The **** adds spice I find."

"B-but why?" Shining Armor gasped, eyes darting to Umbra, but every so often darting back to Twilight's titanic tits.

"It's a funny story, you know. Just the other day it happened, you see. I found a letter for Twilight, a letter from her mistress." Umbra chuckled, remembering the events fondly. "A letter expecting Twilight to submit to her master, to grow her tits a bit so that she can better serve her master. You see, it seems Twilight has been trained for a long time to be a sexy ****, my sweet summer shining. All her life, even when pretending to be a noble princess, it was in fact her greatest desire to become the fuckslave of a great master."

Umbra let go of Twilight's shoulder and summoned the letter into her hand, tapping it as she did so. "She was instructed to grow her modest, useless tits by her mistress so that she could better serve her master. " Umbra could see Twilight pulling the sweater over her head and was quite delighted to find that she had been dressing appropriately even before the breakfast. "You see, I instructed her to grow her tits to better seduce her target. To lure him in so she can be what she's always been trained to be. A sex ****."

Twilight's sweater and baggy trousers were now completely stripped now, and underneath, she was found to be wearing an outfit fit for a sultan's harem. Jewelry of amethysts and rubies decorated her waist, arms, and legs as bracelets and armbands. Her tits themselves were caressed in golden armbands with a golden gossamer fabric that was now beginning to strain under the size of her increased HH-cup tits. Her pussy was covered only by a small pelvic curtain that was sure to leave her completely exposed before even a mild gust of wind. The final touch was that both her belly button and tits were pierced by gems; three shining pearls not unlike the color of Shining Armor's eyes adorned her belly button and nipples.

“Wow.” Shining Armor gasped, eyes bulging. Twilight grinned, preening under his lewd gaze.

“Do you like it?” Twilight’s voice asked him, her grin growing wider and wider, and Shining Armor wantonly checked out every aspect of her outfit. It seemed that no matter how much he looked and stared, he might never get used to it. The look of his little sister all grown up and now ready to fuck like a little whore. There were simply no words that could describe the thoughts in his head.

Thankfully Shining Armor did not gape for too long, if only because Radiant Hope had taken the opportunity to break the silence. “My, my, my, you really have gotten bigger, haven’t you Twilight?”

She marched forwards, with the same grace she had used when cosplaying Umbra, and started to trace her hands across Twilight’s violet tits. For the briefest of moments Twilight considered suggesting that she stop, but Radiant Hope the same skill that she used when cosplaying Umbra was an allure that made a statement with every movement she made. She was in charge, she was a queen, and she would not be denied. At least where Twilight was concerned.

It was a skill that Umbra admired, though she knew that she was able to do it even better if she so wanted. But for now she stood aside and let Radiant Hope have her fun. Soon Radiant Hope was behind Twilight, pressing her own sizable tits into Twilight’s back as she reached forward to grope Twilight’s bust. “Such a wonderful outfit, and such wonderful tits to go with it. But I wonder, if it was through changeling magic that you got your tits, how did you get such a splendid outfit?"

As Radiant Hope talked, Umbra could see that she was glancing at Shining Armor out of the corner of her eye. A glance that held two silent messages. Umbra wasn’t sure if Shining Armor had noticed, but if he had, then the messages were clear. The first was a simple invitation; she was telling him that she had Twilight’s attention and Shining Armor had nothing to fear by ogling his younger sister. The second was a challenge and a warning, daring Shining Armor to claim his sister or else risk losing her to Radiant Hope.

Even when adopting the persona and allure of an evil queen, Radiant Hope still loved to help others. A shame that Twilight wasn’t aware of the silent message, only considering the verbal question.

“It was Rarity; she made it for me a while back.” Twilight admitted, gasping lustfully as Radiant Hope pinched a stiff nipple with her fingers. “She was ordered to make it by… someone. She was told to make sure it would change to fit me if I were to grow bustier. At the time I thought she was referring to my alicorn genetics.”

Umbra didn’t need to be a master genius to figure out that that ‘someone’ was almost certainly the same ‘mistress’ that Cadance had written about in her journal. Not that Radiant Hope had any way of knowing.

“Well she didn’t do a very good job then,” Radiant Hope purred, but her smile was wide and she was clearly teasing. Her hands were tracing the fabric that seemed several sizes too small for her new tits. “It seems a little tight here, and here, and here. Almost like your tits could pop out at any moment. Most uncomfortable, but very sexy. Unless perhaps that was intentional.

Umbra was willing to bet her life that it was indeed very intentional.

“Perhaps a little.” Twilight admitted with false modesty. Radiant Hope chuckled.

"Well, it seems your brother enjoys the view.” Radiant Hope said, pointing at Twilight’s brother. With a dick as big as his, there was simply no hope at trying to conceal it. Nevertheless, Shining Armor still blushed and crossed his legs in a vain attempt to hide his astounding dick, but it was obviously all in vain; there was simply no means to conceal that divine gift and little use in pretending otherwise.

"N-no. Of course not. Twilight's my sister, and I would never—" Shining Armor gasped, shaking his head, but Umbra was growing tired of his pointless denials and was eager to move things along.

"SNAP"

The snap of her fingers may have been unnecessary, but Umbra was always one with a bit of a flair for the dramatic. In any case, it was a wolfish smile that she cast her spell which tore the trousers and pants of Shining Armor as if every thread in the cloth were undone. It was as if he had been wearing nothing at all, and it was clear to everyone that his monstrous dick between his legs had been very erect and it was very much been directed towards her sister. Shining Armor’s hands diving down in a vain attempt to hide it was a doomed effort, even if one were to disregard the fact that his cock was several times larger than his hands.

“It seems that little Shining Armor is more honest about your feelings than you are, Shining Armor." Umbra said gleefully, her presence like a shadow cast over the whole room. A dark spectre that was leading him into a taboo and sinful act that there would be no return from.

But one simple fact was unmistakably dawning on Shining Armor’s face. Twilight simply wasn’t his sweet younger sister any more. That much couldn’t be denied by the ravenous, sinful glint in her eyes as she stared at her big brother’s cock like it was made of gold.

“Looks like some pony wants to have a taste of her big brother’s cock.” Umbra purred, grinning widely. She noticed Shining Armor’s guilt spasm across his face at the words ‘big brother.' "Oh, would you prefer her to think of you some other way? Does it make you uncomfortable to have her address you as 'big brother?' Would you prefer 'king,' perhaps? Or "master"?

Umbra was being insincere, though; she could see Shining Armor’s mighty cock betray him as she mentioned the words 'big brother'. Throbbing every time she did so, just as it throbbed whenever she addressed him as ‘king’ or ‘master’. Poor, sweet, naive Shining Armor; his voice could lie, but his body could not. And Twilight had noticed it too; her violet eyes fixed on her big brother’s cock, Umbra could practically hear Twilight’s heart pounding in her chest, looking at her brother’s dick like Celestia herself had graced their presence.

“Seems like Twilight has noticed how big your cock is.” Umbra said, her eyes staring into his. Shining Armor’s jaw dropped as he saw the unabashed hungry look in his little sister’s eye. “Look how pleased she is.” Umbra’s fingers snaked under the thin fabric of Twilight’s outfit to pinch her nipple. “Look how horny she is.” Umbra’s hands moved from Twilight’s nipple to her dripping cunt. “Look how wet she is. And it’s all because of you Shining Armor, all because of her big brother. Won’t you be responsible for her?”

Shining Armor was gaping, eyes flicking between the three ponies, fingers twitching as if he had to physically resist the urge to wrap them around his meaty cock and start stroking.

Radiant Hope had been watching from the sidelines, smiling as if this was all nothing more than a cute little crush, and Shining Armor was simply a naive fool. She stepped forward, still carrying the same aura that she used at the strip club. She leaned down so her glossy blue lips were but a fraction of an inch from Twilight’s ear. “Go on, Twilight, show him. Show your brother how much you love him.”

Twilight approached slowly; every step was tentative. As if terrified something might go wrong at any moment or that she might be shaken awake from this wonderful dream. Nevertheless, as if on instinct, her body naturally fell into a seductive stride, her hips and breasts swaying in perfect rhythm. In some ways it was even more impressive that it came to her so naturally, especially since she had enlarged her tits so much. Shining Armor said nothing, still looking at Twilight like she was some kind of phantom.

When Twilight was close enough, she knelt before Shining Armor; now his prestigious cock stood tall and higher than her head. Twilight’s eyes looked it up and down like it was the mightiest tree in the forest, then her eyes met with her older brother’s as a silent question was shared between them. “May I?”

“Twily…” Shining Armor gasped, his hands gripping the side of his chair for support. He looked to Umbra and Radiant Hope and found only silent encouragement. “Are you sure?”

Twilight nodded her head frantically. “YES! Sure, I’m sure. Sure as I can possibly be!”

“Then…” Shining Armor gulped, clearly surprised that he was as turned on as he was. “Go ahead.”

Twilight beamed, a full-face splitting beam that would make Pinkie Pie jealous. She mouthed a simple ‘thank you’ and then plunged. Her tongue greedily sliding up and down his cock with a frantic enthusiasm. Her hestitation from before seemed to vanish as soon as she gained her first taste of her older brother’s cock. Frantically sliding up and down, side to side, determined not to leave a single inch of this behemoth unmarked with her saliva and finding every inch of it tastier than the last.

She was through, as through as would be with any test, if not even more so given how important this test was to her. She was more determined than any other test, worshipping cock with such **** passion. Every now and then she would move between his divine mast and his balls, making sure both were well satisfied between her lips. Shining Armor got his part, which was trembling, the lust overwhelming, just as his confusion and shock seemed to only further heighten his lust, in much the same way that the taboo nature of the entire experience did.

"S-so you've been planning this surp-surprise for me?" Shining Armor panted, his hips bucking as Twilight served his cock with passionate devotion.

"Well, partly." Twilight admitted slyly, looking at Shining Armor's cock in curiosity. "Okay, so there may have been one other pony who I wanted to see me with big tits.”

“Who?” Radiant Hope asked, eyes lighting up with curiosity as if this were the greatest gossip in a century. “You simply have to tell me, Twilight; I have to know!”

“Flash Sentry.” She admitted between licks of Shining Armor’s glorious cock. Unfortunately this didn’t cause quite the outcome that Twilight was hoping for, instead simply causing Radiant Hope to scrunch her face in confusion.

“Who?” Radiant Hope asked, looking to Umbra in confusion.

“He’s the one with orange fur and a blue mane.” Umbra said with a shrug. But Radiant Hope still looked perplexed so Umbra summoned a magical image of Flash Sentry to inform her. “I didn’t know who he was at first either.”

Radiant Hope squinted at the image before her. “I may have seen him before, but a plain, ordinary guy like that doesn’t ring much of a bell.”

"He was at your strip club earlier.” Umbra reminded her, but Radiant Hope shrugged. “We fucked him together.”

“You what?!”

“Must not have left much of an impression.” Radiant Hope said, shrugging even as Twilight protested. “To be fair, I fucked a lot of ponies in that job, just like I enslaved a lot of different stallions. And I think a plain guy like that just wouldn’t leave much of an impression.”

“Why does everyone keep saying that about him?” Twilight said, disappointed, breaking her blowjob for a second to pout and folding her arms around her humongous tits. Umbra’s attention, however, shifted to Shining Armor, who was staring at the magical projection before him.

“I know him. He-he’s the one who’s defiled you, Twily? You’re too good for him, and I won’t let him take you away. He’s not good enough for you; no one is.” Shining Armor said, a bit of his brotherly protection instincts coming through. Umbra and Radiant Hope couldn’t help but chuckle.

“The pot is calling the kettle black here. And I thought you ponies were such a tolerant bunch.” Umbra tutted mockingly, shaking her magnificent head.

"Aw, lay off him, Sweetie; that’s just how big brothers are.” Radiant Hope purred, trailing her fingers through Shining Armor’s mane in a comforting pat. “Overprotective of the ones they love, hating to see their little sisters defiled.”

“Or jealous perhaps.” Umbra suggested as she leaned forward to grasp Twilight’s shoulders from behind, her blood-red lips whispering into Twilight’s ear. “But Flash Sentry’s a little busy at the moment. And I’m sure he’s not the jealous kind, is he?”

"No," Twilight said, her body shivering with lust. “He isn’t.”

"So he's not going to be jealous about you submitting to Shining Armor, is he? Heck, if he were here, I suspect he'd be eager to watch. Watch you become a loyal sex **** to Shining Armor, perhaps while he submits as my sex **** right next to you." Umbra whispered into Twilight's ear, her voice like that of a succubus, tempting Twilight into sin. Twilight resumed her blowjob, her eyes wide with worship, a silent plea for Shining Armor to permit her to indulge in this fantasy.

As Shining Armor grunted and moaned under his sister's relentless blowjob, Radiant Hope took it on herself to become the second devil in the room. As Umbra whispered temptations of sin into Twilight's ear, Radiant Hope then proceeded to whisper in the ear of Shining Armor himself. They were like a team, two temptresses of sin and seduction, luring the prince and princess into a tryst of **** and debauchery, but it would be a sexy tryst of **** and debauchery for the two.

"Your sister would make an excellent addition to your growing harem, my king." Radiant Hope whispered into Shining Armor's ear like poisoned honey. "A princess, your own sister. The Princess of Friendship herself and the hero of Equestria being warped into your perfect fuck ****. She's the hero of so many. So many ponies idolize her and look up to her, but now they're all going to be looking up to your whore, your sex ****. Doesn't that make you hard?"

"Ffffuckk yeah..." Shining Armor admitted, his prestigious cock getting harder under the combined efforts of Twilight's blowjob and Radiant Hope's poisoned words.

"You can take her, you know, like you did with those other ponies. Umbra told me about them, and I saw you with those maids. They may have been ordinary guards, servants, and maids, but this is another step entirely. But you could do it, just like with them. You bring the princess of friendship under your spell and make her your sex **** like the others. After that, you'd know that there wouldn't be a pony alive who could resist your charm. Who wouldn't fall under your spell. You’d know you could have all the women in the world and no one could possibly stop you!”

“Oh…oh… fuck…” Shining Armor's cum started to leak, just a smear of pre-cum, but Twilight eyed it as if it were the last drop of water in a vast desert. Her tongue dived for it as if possessed, sloppily licking around for any trace of where the pre-cum had dropped. Seeing this, no one could ever have believed that this was the most intelligent of the princesses; they’d have been convinced she was nothing but a sex-starved animal.

Once again Shining Armor’s eyes were wide with shock. It had been happening to his eyes so often that Umbra wondered if his eyelids might stop working from neglect. But even the dark queen could not blame him for this lapse in thought. Not when his sister had debased herself so thoroughly. His fingers ratted against the chair as he thought, still stiff from when he had been clutching it in anxiety and anticipation.

But slowly, very slowly, Shining Armor found his voice and simply asked with a croaky prayer: “Would you like more?”

Twilight Sparkle’s eyes glazed over, as if she could not dare to hope that she had truly heard what she thought she heard. They glanced to Radiant Hope and Umbra, as if one of them might step in and ruin this wonderful moment for her. Neither did Radiant Hope, simply giving a gentle smile that silently said, 'Go get him, tiger.’

Umbra’s silent words were more mocking; her arms were folded, and her blood-red eyes were staring at Twilight dismissively. Which was only a natural way for a mistress to treat her bitch. For Umbra the silent words were more akin to 'This is what you wanted, isn’t it? To be the skanky sex **** of your dear old brother? What are you waiting for?”

Twilight’s eyes then shifted back to Shining Armor, becoming as respectful and dutiful as they would when staring at Celestia. She needed no words but silently nodded, her eyes brimming with hope twisted with lust and perversion. Her silent message was more obvious than either Radiant Hope or Umbras. "Please, I’m begging you, sweet Shining. 'Please, my master, can I have some more?’

Shining Armor was beaming but also concerned, as if worried he’d gone too far. His constant insecurities—how endlessly frustrating. Umbra was already seeing why Cadance was struggling to turn him into the ruthless master she craved. Especially when every mare in the room was silently egging him on, he was silently asking them, 'Are you sure?’

Frustrated, Umbra had a sinful idea. She simply got on one of those chairs, turning it around and lying on it like a throne. She spread her legs, her ebony pussy already leaking a dark, sinful nectar. Umbra plunged two fingers, both with blood red nail polish, into it, looking for a G-spot. “Please don’t stop on our account.”

Following Umbra’s lead, Radiant Hope had also drawn up a chair and spread her legs. She started to stroke herself, her eyes not as perverted as Umbra’s but alas, still slight with lust. Her smile was more reassuring and gentle as she told Shining Armor like a warm mother: “Don’t be afraid, dear. We’re all enjoying the show.”

Shining Armor turned back to Twilight Sparkle. Umbra could practically hear the hearts thundering in their chests. Suddenly he stood up; at full height, he towered over the kneeling Twilight. Half a god, half an executioner, both sides ready to lay judgment on Twilight.

“If you really want my cock—" Shining Armor swallowed, as if tasting the perverted words that escaped his lips. “If you really want my cum, Twily, then—" His eyes darted around, looking for inspiration. “-Lay back on the table, and—" He swallowed again and **** a shaky smile that did nothing to hide either his lust or his nervousness. “And spread your legs.”

Twilight shot to her feet as if electrified, her hands clapped together as if she had just been told she got a perfect score on her math test. She rushed over to the table, her magic throwing the plates over to the sinks as she did not trust that her shaking hands would not break them.

She lay back on the table, wings spread out as she **** herself backward on the table. Her lust-filled eyes struggled to see Shining Armor; her new enhanced tits were blocking the view. With every breath she took, they rose and fell, blocking Twilight’s vision of everything but her succulent purple breasts. “Yes, yes, please, Shining. Please fuck me and make me yours. Please, my brother, my king, my…my Master.”

Umbra had to admit, hearing one of her greatest enemies begging like that was stirring something in her. Her fingers were digging into an increasingly warm pussy, digging for a G-spot and inspired by Twilight’s prayers of submission. She did that. Umbra did that to her greatest foe; she had made Twilight beg like a bitch. And it felt so good!

Shining Armor did not rush to plunge his meaty cock into Twilight’s pussy, though. Instead, he circled it, inspecting it by tracing his hands around it. Umbra didn’t know if Shining Armor was trying to drum up the nerve to fuck his sister or if he was just enjoying keeping Twilight on edge. Keeping her in anticipation and suspense, letting the imagination of Twilight go wild with lust and fantasy. Umbra knew that she for one was enjoying seeing Twilight pout.

Suddenly, Shining Armor seized Twilight’s tits, a handful in each hand. They were big, much bigger than his hands, and difficult to control. Like balloons filled with water, they were slippery in his grasp and far too big for him to pin down and control, but he nevertheless seemed to enjoy the challenge.

Twilight enjoyed it too, moaning with every brush of her tits. Every time his hands would brush against her rack, she would shiver again; every time his thumb would run across her nipples, she’d let out another moan. Had she enchanted her tits to be extra sensitive? It would explain a lot.

Maybe Twilight could do the same to Umbra’s tits?

Umbra shook her head at the treacherous thought. Her Sombra pride was still strong enough to prevent them from going to their greatest enemy to beg for bigger or more sensitive tits. Besides, the ones Discord had were big enough and plenty ripe too. Almost subconsciously a hand moved from Umbra’s pussy to her tits to scoop a nipple into her mouth to suckle. Fuck, it tasted good. Like dark chocolate laced with a trace of poisoned honey.

Shining Armor, though, was quickly growing bored of playing with Twilight’s tits. And his eye started to wander from her tits to her pussy, still leaking like a river as Twilight’s entire body shivered with arousal. It was sudden when he let go of Twilight, sudden enough that Twilight seemed shocked that it happened. Eyes darting around as if some intruder had pulled Shining Armor off of her. What her eyes found, however, was a much more delightful sight.

For in front of her, Shining Armor was towering over her body; this close to her, she could see him even over her titanic tits. His vast, muscular body blocking the lightbulb at the top of the room and casting a shadow over his horny sister. A hand gripped Twilight’s thigh for support; his grip was tight because his hand was still shaking as he looked at Twilight’s pussy, inspecting it.

His other hand was stroking, and though Twilight couldn’t see it, Umbra could see Shining Armor stroking his cock. Undoubtedly he was preparing to plunge it into his sister’s begging pussy, and wanted it at full mast when he did so. A sudden, surprising feeling of outrage and envy surged through Umbra’s body. Why was he stroking it alone when he had two perfectly good sex slaves here to help? And why couldn’t it be Umbra’s cunt he was fucking?

But Umbra’s internal torment was lost on both Shining Armor and Twilight Sparkle. They only had eyes for each other, for their sister and brother, respectively. Shining Armor still wondering if he was really going to make his beloved sister his bitch, and Twilight Sparkle seemed to be silently begging Shining Armor to do exactly that.

“You want this, Twily?” Shining Armor croaked, his voice raspy with lust and anxiety. Both checking to see how far Twilight wanted to go and teasing her by denying her clear wishes. “You want your brother’s massive, meaty cock to plunge into your alicorn cunt?”

“Yes, please, Shining, I want it! I want it so bad! I want to be fucked and claimed by you so fucking much!” Twilight Armour begged, her legs shivering as she awaited the coming ecstasy as Twilight urged them to spread even further past their limit. Her tits were heaving, bouncing with every breath she took.

But as those breasts bounced, Umbra noticed something: a small heart-shaped locket made of gold was bouncing on her tits. It was small, compared to the size of Twilight’s tits, which was why neither Umbra nor Shining Armor had noticed it until now. Their attention was drawn to it only when it landed at exactly the right angle and snapped open.

Twilight froze; she clutched the locket with her magic, but it was too late to stop anyone from seeing what was inside. A photo of a certain orange unicorn with a mane of bright blue could be seen before Twilight could close it. For a moment there was silence in the room as worry crept into the passion.

Would Shining Armor chicken out? Would he become too scared to continue? Would he see cucking Flash Sentry as crossing a line? Or perhaps be reminded of his own wife and allow his guilt to take over? Perhaps he’d be snapped out of his brazen lust and his pesky morals returned to him? They waited in bated breath.

“Shiny? Please. I really do want this. I don’t want to stop.” Twilight was begging, worry seeping in and the beginnings of tears forming in her eyes. Terrified of the cruel possibility of having everything she wanted lined up before her and then being ripped away.

Umbra understood Twilight’s fears, but she could see Shining Armor’s mind working. She could practically hear the gears in his head begin to turn; he wasn’t considering giving up. Not right now; something else was entering his mind, something born out of lust, and his recently found desire to dominate women was speaking in his mind.

“You want me to fuck you?” He asked, speaking more slowly now, his eyes becoming dark and calculating. He wasn’t dismissing the idea outright, not any more. Something else was being considered in his mind, perhaps some way that both him and Flash Sentry could be satisfied. Either way a devil was speaking on Shining Armor’s shoulder, and Umbra was quite curious to hear what it had to say.

“You’re greedier than I thought, Twilight, wanting to serve both me and Flash Sentry.” Shining Armor teased, with a cheeky smile.

“Wha-what?” Twilight asked, mind shutting in confusion. This was undoubtedly not the response she expected.

“You selfishly demand the right to be fucked by me whilst also wanting to see Flash Sentry on the side? You want to have your cake and eat it too?” Shining Armor demanded, but it was only a mock accusation in his voice. A playful ribbing, but Twilight didn’t seem to understand that, for her head was shaking from side to side.

“It isn’t like that.” She pleaded, terrified that her wet dream was about to become a nightmare. But Umbra knew better, knew she had nothing to fear.

Shining Armor was shaking his head, tutting in mock disapproval even as the smile didn’t leave his face. “What am I going to do with you? So selfishly wanting to have both my meaty cock and Flash Sentry’s too without anything in return?”

Umbra was now furiously masturbating harder now, fucking herself with sudden fanatic desperation. Where had this sadistic Shining Armor been? She liked it. It was sexy. It was hot. It was-

She moaned. Umbra, Queen of Darkness, the greatest enemy of the Crystal Empire, had moaned thinking about her enemy Shining Armor. What was worse is that nobody had seemed to care, least of all her!

Twilight, though, wasn’t picking up on the cues; her head was thrashing. “I would never, Shiny—it wasn’t anything like that. I wasn’t selfish.”

“You weren’t? So tell them, Twily. What were you going to give Flash Sentry and me in exchange for fucking a slut like you?” Shining Armor teased, but there was only a playful malice in his voice.

“ANYTHING?!” Twilight screamed from the bottom of her lungs. Umbra couldn’t help herself anymore to see her enemy debase herself like that. She threw her magnificent head back and screamed as she came, hard. But no one paid her any mind, which was both the cruelest insult and the hottest thing ever.

“Anything?” Shining Armor teased playfully.

Twilight Sparkle seemed to be calming down or noticing the playful cues in Shining Armor's face.

“Anything.” She repeated.

“Anything at all?” He asked, his playful grin filled with mirth.

“Anything at all.” She repeated, a weak but eager grin coming to her face as she caught on to the implications.

“So you would be willing to declare yourself my ****? Brand yourself as nothing but my property? Existing to serve my every need and desire?” Shining Armor asked, with a playful mock disinterest. As if they were simply discussing a few chores.

“Yes, yes, of course, Shining.” Twilight gasped, her smile growing more confident as she realized exactly what Shining Armor was asking for.

“If I call, would you come straight to me to spread your legs and take my cock? Would you brand your cutie mark with my symbol so every pony will know that it’s your special talent to be my sex ****? Will you cook, clean, and work for me should I ask it, no matter how tedious the task? Will you research ways to further improve your sex appeal and that of my other slaves?” Shining Armor asked, speaking faster with every word that came out his mouth, repeating ideas and fantasies as soon as his mind conjured them.

Twilight heard the word ‘other slaves’ and shivered in shock and lust as she considered the implications. The implication that Shining Armor had already taken a few steps to become the **** master that both Cadance and Twilight craved.

“YES! By fucking Celestia, YES!” She swore, legs twitching as they anticipated the moment that Shining Armor would finally plunge his dick into her and claim her as his own.

“And when I don’t need you, when I am busy using some of my other slaves, will you be willing to call Flash Sentry Master? Just as I expect you to call me the same? Will you do everything I ask you to do for me for him as well?” Shining Armor asked, leaning forward, his dick creeping ever closer to Twilight’s drooling cunt.

“Oh Master, you’re so kind. So generous to share me with Flash Sentry. YES! Of course I will. Whatever you want, whatever he wants, Master!” Twilight moaned. “Oh fuck it feels so good to call you that. Master! Master! Master! MAST-"

She was cut off by the feeling of Shining Armor's cock finally plunging into her cunt. Whatever defenses or resistance that may have existed inside Twilight’s body against such a huge cock as Shining Armor’s were easily broken as he plunged into his sister. The first thrust was the hardest as Shining Armor broke into Twilight’s pussy, her screams of delight enough to shatter eardrums. It was so hot.

Of course Shining Armor was not doing this to pump once and pull out, and soon his rhythm began. He was pounding into his sister’s cunt with a savage speed, like a lustful beast had been released from his heart and now possessed his entire body. Umbra had seen that beast before, but now it was on a whole other level, fuelled as it was by the taboo thrill of fucking none other than his precious sister.

Twilight’s breasts were bouncing wildly, and it was possible that the perverted alicorn princess had gotten carried away when pouring changeling magic into them. They bounced against the table, against her stomach, into Shining Armor’s chest, against Twilight’s face and against each other in the wild lovemaking between brother and sister. But Twilight didn’t mind; if anything, she registered every slap of her new tits with the same ecstasy that any masochist would receive from a whip or spank.

Umbra was getting horny again, despite the fact that she had just cummed a few moments ago masturbating to the sight before her; her body was reacting as if she hadn’t cummed at all. If anything, she was growing more horny, more stimulated, more ****. And how could she not be? The pious and pretentious Princess of Friendship was right there! Being fucked stupid by her brother and screaming about what a **** she was! Each word out of Twilight’s mouth was like music to her ears.

“Fuck, Master! You’re so big, and your slutty **** is so tight. Keeping fucking me, please! I’m begging you to debase this royal princess into your perverted cock sleeve. I like to serve, to fuck! To clean, cook, and cum or whatever you want me to do, Master. I am nothing; I deserve nothing but the right to serve you! Please keep fucking my nasty cunt as long as it pleases you, Master; keep using it as much as you want. And if you wish to discard me like any other toy once you’re done, feel free. I exist to serve you after all!”

“Fuck, it’s too much.” Umbra moaned, standing up. Her fingers simply wouldn’t cut it anymore. The sight before her was simply too much for mere masturbation. It was time to take a direct hand in these affairs. She got to her feet, her statuesque figure drawing the attention of both mare and master as she did so and marching across the room, her heels clicking across the floor like a general inspecting soldiers.

“You’re doing well, my King. Very well indeed.” Umbra said, two fingers guiding Shining Armor’s gaze away from his sister and towards her. "Your domination over your sister is truly worthy of legends. It’s even enough to make me wet.”

To emphasize her point, Umbra put two fingers in her sopping cunt and soaked them in her juices before showing them to Shining Armor. “You can taste for yourself if you want.”

A wide grin was plastered on Shining Armor’s face, but a shrug of his shoulders and shake of his head confirmed he wasn’t eager to taste Umbra’s cum straight from the source. Yet.

“Your loss.” Umbra said with a shrug before licking her fingers as if they were lollipops, making sure to take great effort to show how much it was turning her on. “But in all seriousness are you really going to **** your queen like this?”

She took Shining Armor’s hand from his sister’s thigh and placed it on Umbra’s succulent tits. Her diamond-hard nipple throbbing against the palm of his hand. “You feel that? Feel what you’re doing to your queen here? Feel how you drive me to madness with such a display of power, taboo, and perversion?”

"Oh, you poor dear.” Shining Armor teased; the sarcasm wasn’t lost on her. A flush of indignation filled Umbra at Shining Armor’s teasing words. “You must be suffering.”

“Hmpf…” Umbra said with a playful, overly dramatic scoff. “It’s your own fault, you know. What did you expect, fucking an enemy of mine like that? Degrading her, making her your ****, making her say such sinful submissive things. It would be enough to make any bitch like me dripping wet.”

“And what exactly do you want me to do about it?”

“I would have thought it was obvious.” Umbra said, turning on her heel and walking alongside Twilight’s outstretched body, two blood-red fingernails tracing her as she walked until she was standing side by side with Twilight’s face, casting a shadow over her.

“I would like a piece of the action.” She leaned forward, a sadistic smile on her face as her sharp fingernails clawed around Twilight’s face and made those violet eyes look into Umbra’s red ones. Like a predator with her prey in her class. “It seems only fitting for your greatest ****, your queen ****, to have a piece of the pony who once defied her.”

Umbra took great pains to maintain the appearance of the sensual seductress, trying to hide the desperation that was throbbing inside her. The overwhelming lust that threatened to overtake her and drive her mind to mush. She desperately wanted—no, she needed Shining Armor to say yes. Before her mind turned to mush under this cruel lust.

“You want to ride Twily’s face as I fuck her.” Shining Armor asked, and Umbra nodded a little too quickly. “And what do you think, Twily?”

Twilight opened her mouth to speak. Whether to agree or to deny Umbra didn’t know, but she refused to take a chance. Two blood red fingers, still stained with Umbra’s cum and saliva, were pressed over Twilight’s lips before she could utter a single syllable.

“You forget yourself, my king. It’s not the place of a **** to set terms, to make conditions, to deny you. It is her role to obey and to relish the opportunity to have served you.” Umbra reminded him, her voice like that of a sensual noblewoman. A trace of arrogance mixed with an irresistible allure that could make men cream their pants.

“True, true. Very well. Twilight, make sure you serve your queen as well. Her orders are my orders.” Shining Armor said, before he warped and elbowed around Twilight’s thigh to pull himself particularly deep in her. Twilight responded by screaming with joy and wrapping a foot around the back of his head and pulling him in closer.

“Elegantly put, my King.” Umbra said, lifting a magnificent leg over Twilight’s head and staring down at her so that Twilight’s vision was filled with nothing but Umbra’s ass and the bottom of her ass. Umbra could no longer see Twilight’s eyes; her vision was covered by Umbra’s own prestigious breasts, but she imagined Twilight’s eyes glazed with lust and perhaps just a trace of fear at being at the mercy of her old foe.

Umbra squatted down until she felt her pussy trace Twilight’s face, the alicorn’s horn nestled between her ass cheeks. It was enough to make even a majestic figure like her shiver, and as a cherry on top, it gave her such a perfect view of Shining Armor pounding into her sister’s cunt and Twilight’s wild, bouncing breasts.

“Lick, ****.” Umbra ordered, but the expected feeling of Twilight’s tongue on her pussy did not come. She pressed her thighs together, squeezing Twilight’s face like a grape and denying her oxygen. “I SAID LICK!”

If Umbra had any fear that Shining Armor would interject at the **** of her sister, they were quickly set aside as she felt him pound into Twilight with greater efficiency. Perhaps some latent sadism was coming out, perhaps fuelled by a subconscious jealousy of his sister. It was just speculation; more likely, he found the display before him hot.

And he wasn’t the only one; Twilight seemed to have gotten only hornier as Umbra’s actions broke through whatever hesitation Twilight had, and she started to lick Umbra’s pussy. Her tongue squeezed through her pinched cheeks to sloppily taste the cum leaking out of Umbra’s pussy, growing more and more enthusiastic with every drop of cum she could taste.

It sent ripples of lust through her body; the sex was only a small part of her growing ecstasy. In truth, the real thrill was knowing that this was Twilight Sparkle! Hero of Equestria! What greater thrill for a villainess was there than having her lick her cunt. Imagine if Queen Chrysalis could see her now! Or Tirek! Or the Sirens!

Umbra could hold it in no longer and threw her head back in a moan of ecstasy as the thought occurred to her. It was perfect; nothing could stop her now! This was all she ever wanted. She didn’t know if it was the thrill of victory, the pleasure of ****, or simply the lust of having an enemy serve her like this, but Umbra could feel nothing but lust and triumph.

“Oh fuck, the three of you like that. You’re making this poor girl jealous, you cruel Master. Leaving me unattended!” Radiant Hope gasped, now on two feet with her legs spread and digging as deeply as she could into her pussy with her fingers as she looked at the display before her with a maddening obsession.

“It does seem cruel, doesn’t it, my King?” Umbra said, with a wide smile on her face. “Perhaps you ought to reward my dear friend here for helping you find the courage to take what you deserve.” She emphasized her point by slapping Twilight’s tits, making them slap into each other.

“Hmm…” Shining Armor said, grinning teasingly. There was no hesitation in his voice now, no shame nor guilt nor worry. He was, at least for now, unconcerned with going too far and was fully embracing the thought of being the **** king Twilight and Cadance wanted him to be. “I’m assuming you have something in mind for her?”

“Besides allowing her to watch?” Umbra teased. Why did it feel so comfortable to talk to Shining Armor like this? He should be an enemy, but here they were, teasing each other like old friends. Umbra banished the errant thought from her mind and focused her attention back on the scene before her and the question of Radiant Hope.

“She could make a magnificent ally; she did, in fact, inspire me in the arts of seduction and domination.” Umbra admitted, her mind drifting back to the night at the strip club. “And I’ll say this: she can pull a wonderful cosplay of me off, if you ever wanted a twin fantasy of me.” Umbra said with a wink. Shining Armor looked up at Umbra, struggling to tell if he was joking. Umbra simply smiled and kept him in suspense.

"It's true, Master. I've known Umbra a long time, since he was Sombra and even a child, and—" Radiant Hope then started a pitch-perfect impersonation of Umbra's voice. "-I know how to bring the haughtiest princesses, the most influential nobles, and the most powerful mages to heel with just a wave of my tits and a shake of my behind."

Umbra didn't know whether to be annoyed, flattered, or aroused by Radiant Hope's pitch-perfect impersonation of herself. Or at least her mind wasn't sure; her body had made its choice almost immediately and had chosen arousal as its response. Perhaps in solidarity with Shining Armor, who let out a delighted groan at the impersonation. "Fuck, that is hot. Perhaps I'll set you up as a teacher for the other slaves. If you're anything like Umbra here, you'd make a wonderful addition to my depraved court."

"Look at you making plans." Umbra purred, half teasingly, half intrigued. "Are you already imagining it? Imagining having an entire empire of sex slaves and loyal cumdumps? Are you perhaps making plans to make those dreams a reality? To bring all of the Crystal Empire under your sway and to rule it as a perverted tyrant?"

"Oh fuck! Wha-what am I doing? Twilight... Cadance... Umbra... it's so hot though..." Shining Armor was speeding up. The timid voice of his morality was desperately trying to make itself heard over the all-consuming fire of lust in his heart, but Shining Armor allowed it to be drowned out. In this moment he wasn't listening, he was having the time of his life fucking his sister and plotting plans to be the **** king. Twilight too was responding to Radiant Hope's dirty talk, or perhaps just to the relentless pounding she was receiving by licking Umbra's pussy ever more passionately. The scent of sex in the room was so thick you could almost taste it; it was simply so overwhelming.

It was coming. Umbra had a sixth sense by now, but she knew an orgasm was coming from Shining Armor. And with it was another cast of his unique brand of magic; Umbra could recognize the signs. She could sense the wicked, dominant magic in the air; she could see Shining Armor's horn start to throb with power as the rest of his body was throbbing with lust and craving release. He was about to cum, and in doing so he would chain Twilight Sparkle to his control, warping her cutie mark and with it her destiny into his perfect sex ****.

"Do it, Shining Armor. Cum in her, take her. Do it. She wants it; we all want it. Don't hold anything back." Umbra ordered, looking him dead in the eye, and he needed no more invitation. Ignoring the small voice of morality in his mind still trying to hold him back, he pressed on.

It came suddenly but explosively, with a hefty push and a heavy grunt; Umbra could hear the thick cum shooting into Twilight's womb. She couldn't see it at this angle, but she could smell the thick cum leaking out of the princess's pussy and oozing to the floor. The smell was enough to stir something in Umbra, and soon she too found herself throwing her head back in ecstasy and cumming her brains out. Her tainted cum, staining Twilight's face and marking her as forever being tainted by Umbra’s cum.

It wasn’t only Umbra who’d be marking Twilight; however, Shining Armor, for his part, was pumping quickly, banking magical power. Upon summoning enough magic, he unleashed it upon Twilight, attempting to bind his sister to his will. It was harder for him than the others he had branded; Twilight, after all, was no mere unicorn but a full alicorn with all the magical power that would entail.

Nevertheless, Shining Armor's magic quickly proved itself superior, in part because Twilight was already eagerly submitting to Shining Armor. As such, her magical barriers were laid open, and Shining Armor effortlessly overpowered them. Soon his magic was penetrating to the deepest parts of her entire soul and rewriting it in line with his desires. Her cutie mark warped and changed, though the change to her mark was smaller than the others, simply consisting of a chain being wrapped around it.

Speaking of chains, a new one had just formed in Shining Armor’s hands, the same brilliant blue as his magic. It was connected to a collar that was summoned around Twilight’s neck and bearing Shining Armor's cutie mark. Forever branding Twilight as belonging to her brother and to any pony who knew anything about **** magic, she would be declaring to all that she was enslaved to her brother and that bond had been cemented in sex.

Shining Armor pulled out, leaving behind an oozing river of cum leaking out of her cunt. Umbra, releasing her hold over Twilight’s head with her thighs, walked around to inspect it. With two fingers she scooped up the thick substance and brought it to her lips. It was as tasty as thick icing and flavored with the tangy taste of Twilight’s cum. The thought amused Umbra as she considered how the cum of other ponies might also flavor Shining Armor’s delightful cum.

“Delicious as always, not that any **** would expect any differently from their king.” Umbra said, scooping another taste. “We should experiment more, my king. See how your cum tastes when flavored with the taste of a few other ponies. Maybe a few threesomes would really help add to the taste, mixing the cum of some of the tastiest cunts?”

Umbra was pleased when she saw that Shining Armor’s cock still had some energy left in it, as it was hardening again. Not up to full mast, but with a bit of encouragement, it was perhaps possible. This stallion was insatiable! How absurd was it that he had repressed himself for so long?

“Sounds like you like the sound of that. But we should make sure the cum isn’t wasted.” Umbra said, pointing at the cum leaking out of Twilight’s pussy like a tube of toothpaste. No matter how much Twilight desperately wanted to keep it all in, the simple reality was there was too much for even an alicorn to handle. “Radiant Hope, be dead and clean it up.”

Delighted to be involved, Radiant Hope got to her feet in an instant. With a wave of her magic, she summoned up a maid costume for herself and made her way to Twilight. Kneeling down on her platform heels, Umbra and Shining Armor were treated to quite the sight of Radiant Hope’s backless outfit and the crack of her ass clearly visible beneath her short skirt.

“You’re doing well, Twilight. Keeping all this cum in.” Radiant Hope said, in between her licks of the ambrosia-like cum. “Especially for a beginner, this is very good.”

"Well, I’m only as good as my teacher.” Twilight admitted modestly. She seemed unable to moan now, simply because she did not have the energy to make herself scream.

“Teacher?” Shining Armor asked, finally finding his voice and staring at his sister with a quizzical expression. “What teacher? How? When? When would you have been taught to do—" He waved his hand in the air, seemingly unable to bring himself to say the words. "This?"

“I-I’m afraid I can’t say.” Twilight admitted, face falling. “She’s my mistress, Master, and she has ordered me not to say.”

“Even from your Master?” Shining Armor asked, a note of displeasure in his voice.

Twilight sighed in disappointment. Radiant Hope had stopped licking her cunt to look curiously at Twilight, and similar expressions of curiosity were shared by Umbra, yet still Twilight shook her head. “I’m sorry, I can’t tell you more, Master. Please forgive your disobedient ****… or punish her if you prefer.”

She lifted herself slightly and spread her legs a bit more, awaiting punishment. Yet Shining Armour didn’t bite. “You said you’d do anything for me.” He said, a hint of accusations in his voice.

“I’m really sorry, Master.” Twilight said, averting her gaze. “But it’s not that simple.”

“Even I don’t know who this mistress is.” Umbra said, walking forward and giving Shining Armor a handjob as she spoke. But more to keep herself from fidgeting than anything else. “I have interrogated her on the subject already, but she didn’t break. I suspect that this ‘mistress’ will reveal herself in time.”

It was a disappointing answer for Umbra, Twilight, and Shining Armor, but nevertheless, it was an answer that they all accepted. But still, it would not be fitting for Umbra to allow such a delightful coupling to end on such a disappointing note, so she changed the subject. “So how did it feel to fuck your sister? To make her your perverted, broken sex ****?”

Umbra’s grin was as wide as a cat's. Twilight Sparkle was looking at her brother like a prisoner awaiting judgement. Radiant Hope had returned to licking any stray strands of cum out of Twilight’s pussy, but Umbra could tell that she was listening. All sound in the room had disappeared, replaced with an awkward silence.

Perhaps it was because it was being presented to him so bluntly, but it suddenly started to dawn on Shining Armor what he had just done. The sheer enormity of his crime and taboo act was dawning on him. But his freak-out was not as **** as before, not the same as with Silver Shield or any of the maids. His reaction was numb, muted. Perhaps there were only so many times one could keep shocking themselves with how perverted they could be.

“Well… it was certainly an… experience.” He said, but the words sounded like they had been **** out. He kept a smile plastered to his face, but it was quickly becoming hollow and thin. His eyes seemed to be at once darting around and perfectly still, as his pupils seemed to shake.

“I think it’s best…ahem…” Shining Armor coughed, his body betraying him. Umbra had not let go of the cock she was stroking and could feel it betray him, growing harder as the full weight of his actions caught up to him. The flame of his lust refusing to be snuffed out by any trace of guilt or love for his sister. “I think Cadance will need me. In the throne room I mean.”

With a wave of his hand, his magic summoned him some clothes. But whether he was rushing, doing so at such speed, or because he was distracted, it became obvious to everyone that he was emerging from certain illicit activities. What with his scuffled hair, his rumpled skirt, and the simple fact that he’d left his underwear behind when he’d frantically rushed out of the room.

Umbra smirked as she watched him go. He may be her king now, but it was still delightful for Umbra to see her former enemy so humiliated. She picked up the forgotten pair of underwear and sniffed it like it was a vase of flowers. Relishing the look of envy that was etched into Twilight’s face as she did so.

“Would you like to return them, Twilight?” Umbra asked, mockingly offering the underwear to Twilight. “Return them to your dear brother when next you meet? Or perhaps you want to keep them to yourself like the nasty slut you are.”

Twilight stood up, Radiant Hope, having successfully cleaned all the errant cum that had been leaking down her thighs, snatched her brother’s underwear from Umbra’s possession with a scowl. Her eyes betrayed her humiliation, and Umbra knew her pride had been stung. Just as Umbra knew that Shining Armor would likely never see those underpants again.

“He seemed to be in a rush.” Radiant Hope said, hoping to defuse the tension. As she got to her feet and straightened her maid outfit, Umbra noticed she seemed disappointed, and Umbra guessed that not as much cum had leaked out of Shining Armour’s cock as she might have hoped.

“He’s still learning.” Umbra admitted with a shrug. She rose to full height and claimed a chair for herself to slouch on like a queen. With Shining Armor gone, she was the one in charge, and she intended to act like it. “Yet he’s still got a ways to go.”

“Learning? So are you the mistress that Twilight was talking about earlier?" Radiant Hope asked, a pointed finger darting between them. Before she placed her hand on her hips. “Then what were you getting all worked up about before? You seemed genuinely upset in your dream.”

Umbra shook her head, laughing a little. “No, no, it’s not me, my sweet Radiant Hope. I would like to know who it really is as much as you would, but I honestly don’t know. Especially since Twilight here refuses to say.”

“That’s right. "Those are my orders. My mistress said not to tell any pony, and I won’t.” Twilight said, placing a hand on her hips.

“You don’t need to worry, Princess; I wasn’t going to ask.” Radiant Hope assured her. "Besides, Umbra here knows I love a good mystery. We used to read mystery books all the time and make theories. Of course she was always right about them.”

“What can I say? I have the mind of a killer.” Umbra said, shrugging. Pretending that she wasn’t as smug as she was.

“And one of a mistress.” Radiant Hope said, turning to smile at Umbra. “You should have told me that you were training Shining Armor to be a **** king.”

“Didn’t I already?" Umbra asked, frowning as she thought back to the events. “Did it slip my mind?”

"Well, you might have, but you should have said how good you were!” Radiant Hope said, bouncing on her feet. “It was dominance unlike anything I’ve ever seen. You’re going to make him the ultimate **** master in history.”

“You know what the funniest thing is?” Umbra chuckled, no longer bothering to keep the smug grin off her face anymore.

“What?”

“It was his own wife who set me up to it. Can you believe it?” Umbra asked, her smile like a shark's, just like her teeth. “His own wife has set me up to turn him into a fucking sex king. Fucking and using women like slaves and then discarding them.”

“You’re joking!” Radiant Hope said, eyes round with shock, but the giddy smile on her face betrayed a different emotion entirely.

“I’m not.”

“She’s the princess of love!” Radiant Hope gasped, covering her wide grin with her hands. Distantly Umbra could hear Twilight masturbating to this news herself, or perhaps she had just found herself as insatiable as her brother.

“I know, but apparently she’s also a huge slut as well.” Umbra said with a shrug. “Isn’t that the hottest thing you can imagine? The goddess of love, the paragon of marriage, family, and devotion, is actually a huge pervert and slut. I bet you she spends every day masturbating to how she’s defiled her purpose with her lewd fantasies or cumming to what a hypocrite she was.”

Umbra was being a bit facetious, but she enjoyed the idea that the holier-than-thou princess was in fact a complete hypocrite. Sure, if Cadance were here, she’d no doubt go on a longer than needed rant about how love comes in many forms and all couples have different preferences in the bedroom, but in all honesty, Umbra simply preferred her interpretation. Made the old villainess feel good about herself.

She was broken from her thoughts by the sounds of erotic screaming. It seemed that Twilight had been masturbating when she heard Umbra talk about what a pervert Twilight’s sister-in-law was, or that was because she had been sniffing Shining Armor's underwear when she thought neither Umbra nor Radiant Hope was looking. It seemed that another orgasm had been too much for the princess of friendship and had knocked her out cold.

“Well. That’s something you don’t see every day.” Umbra quipped, striding over to a broken Twilight sleeping on the ground. She gave her a slight nudge with her heel but found that it had no effect in rousing Twilight from her lust-induced slumber. “Seems she really pushed herself too far with that one. Might need some more stamina training, or perhaps the thought of fucking her brother was too much for her.”

“I suspect that both might be the answer.” Radiant Hope said gently, leaning down and summoning a pillow with her magic for Twilight to rest on.

“Tell me, Radiant Hope, is there any greater feeling?” Umbra asked, as she traced her fingers across Twilight’s cheek and tits. “Then seeing your enemy debase themselves like this? Becoming a perverted skank to her brother, fucking themselves into a near coma? All to be the ultimate sex **** she could be.”

With Twilight too weak to stop her, Umbra reached into her pussy and took another dollop of Shining Armor's cum that was flavored with Twilight’s juices and tasted it. “To see her defeated, ruined, broken. She was once so defiant; ironic, isn’t it? That a hero like her once fought so desperately to protect this empire from my rule, and now she gets off on seeing it be enslaved by me.”

“There’s a difference between the two. Remember?” Radiant Hope reminded Umbra, who simply shrugged.

“Not too big of a difference, I would say. But I suppose these perverts simply prefer to be ruled by Umbra than Sombra. They prefer to submit to my big tits and perfect ass rather than a shadow king any day. Do you think Discord knows? Knows that all he did with his punishment was grant me the keys to this kingdom?”

“I think he was counting on it.” Radiant Hope said with a grin. “Speaking of which though, how is all that going with you? I remember you were having some identity issues with your Sombra and Umbra sides. But you seem to have gotten them resolved.”

Umbra frowned, having not given the subject any thought. She thought back to the last few hours, slowly trying to unravel what was going on with her psyche. “I think they have come to an arrangement. I prefer to be called Umbra it seems; it just feels right in this body. And it’s much simpler than trying to explain to others the connection.”

Umbra sat down on a chair, claiming it as her throne as she mused on the dynamic of her mind. “Not to mention, for those who are not in the know, the name Umbra isn’t as feared. It lures them into a false sense of security, allowing me to seduce them, to claim them, to own them. All too easily.”

“I didn’t mean names; I meant personalities.” Radiant Hope reminded Umbra, who shrugged.

“They are more similar than I originally thought. Both desire power and dominance; both enjoy the breaking of our enemies. Whether in the bedroom or in the battlefield. And quite simply, I found quite a few uses for my Umbra side in the last few days.” Umbra admitted with a cheeky grin. “But make no mistake, Sombra is not gone. He waits until Umbra is satisfied, after orgasms and particularly intense lovemaking or dominations, and takes control. To plot, to scheme, and to relish in my growing victory over my foes.”

“Your growing victory?” Radiant Hope asked, raising an eyebrow.

"Why, of course. Every victory in the bedroom helps cement my power over them; when I control their sex drives, I control them. Should we ever fight again, they will not be able to stand against me. Simply because every instinct in their body will be begging them to submit, to surrender, and to embrace their true place at my feet.” Umbra gloated, her voice rich with dark sensuality and sexual malice.

“So you’re still scheming to betray them?” Radiant Hope asked, disappointed.

“Oh, not quite. It’s a possibility, but I suspect that there’s far more power to be gained by being the power behind the throne. The queen in the harem is ruling not with an iron fist but with an erotic whisper. After all, does it truly matter if it’s me if Shining Armor sits on the throne of the Crystal Empire if I’m the only one he listens to?” She asks, her voice dripping like positioned chocolate, sweet and sinister. She knew now of the power her body and sexuality wielded and was determined to use it to her fullest extent.

Radiant Hope seemed satisfied by that answer, or at least she was satisfied by the fact that she could be pretty sure that Umbra wasn’t going to go full tyrant with mind control helmets any time soon. Umbra had evolved past such primitive methods of control.

“So what should we do about Flash Sentry?” Radiant Hope asked, glancing at Twilight.

“Hmm?” Umbra asked, surprised at the sudden change in subject.

“I mean, how will we explain things to him? Surely he’s going to be a bit surprised when the princess of friendship starts calling him Master. I do have to wonder just exactly what his reaction will be when Twilight Sparkle herself throws herself down at his feet and begs to be claimed, to be enslaved, and to call him her master? I’m quite certain it’ll be quite fun to watch.”

“I do hope you’re right, Radiant Hope. To see such a plain, boring pony react to the princess of love throwing herself at his feet will be fun to watch.” Umbra said, smiling wickedly. “I do hope, however, he doesn’t prove to be as timid as Shining Armor. My patience does have my limits.”

As if summoned by fate itself, there was a knock at the door at that moment. Before they could realize that Shining Armor hadn’t seen fit to close the door behind him, it opened, and walking inside was a familiar member of the Royal Guard.

“Your Majesties, Princess Cadance said to…" He trailed off, unable to form words in his voice. His eyes darted around, his nostrils widened, and his hands shook as his brain short-circuited. Perhaps it was the overwhelming smell of incestuous sex in the air; perhaps it was the gorgeous figure of Radiant Hope, still dressed as a slutty maid with cum dripping down her cleavage. Or perhaps it was the sight of the naked dark queen who had not long ago dominated him so completely. Or perhaps it was the sight of the Princess of Friendship herself, knocked into a drunken stupor from the sheer lust of that incestuous sex, but whatever it was, it seemed that Flash Sentry’s brain had simply short-circuited.

“Ah, my dear stallion…umm…” Umbra’s smile was deceptively wide even as she struggled to remember his name.

“Flash Sentry.” The blue-maned Pegasus gasped hoarsely.

“Of course, Flash Sentry.” Umbra snapped her fingers as the memory came back to her. "Well, why don’t you come in and get comfortable? We were just talking about you, you see.”

But at that moment frantic footsteps rang in the hall, and a panicked voice yelled out. “Wait, Flash, don’t go in there!”

The unicorn skidded to a stop, panic laid bare on his face as he glanced between Umbra, Radiant Hope, Twilight, and Flash Sentry, who had caught them all red-handed. As a baffled Flash Sentry looked to a panicked Shining Armor, the captain’s face went white.

“Fuck, this is awkward.”
