Cadance has been having dreams. Dreams that leave her yearning, unsatisfied. Flurry knows why, and how to help. It involves a certain unicorn, who's been whispering in her mind for years. They'll all be happy once their King is back to dominate them.

It hadn't been easy. He'd been defeated, destroyed, reduced to something less than living. But he'd found a way. Years and years of slowly, subtly manipulating the Princess' daughter, raising her as his adoring plaything and twisting her body into that of a perfect slave, ever since she'd been just a naive little filly. And finally it would all pay off. All the pieces were in place, and the Empire would be his once more, along with the mare who'd stolen it from him.

Love the Chains that Bind Your Life

Cadance sat at the table, staring at her daughter from above her glass of water, then staring at her own reflection in the glass. Her pink feathers were ruffled and stood askew on her wings, her mane was messy and tangled, and her eyes looked tired and weirdly unfocused. Flurry, on the other hand, seemed mostly fine. She did show some signs of tiredness, but nothing out of the ordinary. And though her nipples did poke through her dress, it was probably only a consequence of the young Princess refusing to wear a bra.

"Is everything alright, mom?" Flurry asked, snapping her out of her train of thoughts.

Cadance shook her head, realising with a tinge of embarrassment how she'd been staring at her daughter's chest. It was somehow bigger than her own, but that wasn't a valid excuse. "I'm fine, yes. Just a bit tired." It would have certainly helped if Flurry's cleavage hadn't been so exposed. She'd been getting bolder in that regard. Or maybe, Cadance thought, she'd just started to notice it more. Either way, they'd need to have a talk about it. Once Shining came back from his mission. That would still take a while, unfortunately, according to his last letters at least.

A set of two maids walked in, both looking even more dishevelled than Cadance herself. Their uniforms seemed to have been thrown on in a rush, and as they removed the empty plates from the table Cadance couldn't fail to notice a hint of frustration in their eyes. A passing glance between the two. A smudge of blue on one's cheek, the same colour as the other's lipstick. How one of them had failed to properly lock her bra, and her nipples were starting to poke through her uniform. And the smell lingering in the air.

"Mom?" Flurry called again, extending a leg under the table to poke her mother's with a hoof. "Are you sure you're alright? You seem worried about something."

Cadance gulped. "I was just... I was thinking about your father. He's been gone for a while and I worry about him." Her thighs quivered, and the alicorn bit her lower lip. She was probably just imagining things. She stared at the maids as they left the room, only to see one of the two slide a hand below the other's skirt just as the door closed. Swallowing again to choke the sound that would have come from her mouth, she stared down at the table. Definitely imagining things. "I think I'll-" Was Flurry playing with her nipples? The Princess shook her head and stood up in a rush. "I need to take a break," she said, walking out of the room.

With a smile on her face, Flurry licked her plump lips, then slowly stood up. Swaying her hips from side to side, she walked behind her mother, distant enough to not be seen. Not that Cadance was likely to notice her in her state. The clacking sounds of her mother's hooves against the crystal floor were easy enough to follow, though she already knew where she was heading. She'd get there first anyway. As she passed by a guard, though, Flurry let her hand wander to the side, to subtly run one of her long nails over the taut fabric covering his crotch. Then she rounded a corner, still making sure her ass jiggled with every step, and disappeared in a flash of light.

Flurry held her breath, as a shiver of pleasure ran through her spine. She was panting, sweating, and just barely able to hold her hands away from her sex. Instead, one of them was on her mouth, curled up in a fist to stop any moan from leaving her lips, while the other roughly toyed with one of her nipples. Her broad wings stood stiff, awkwardly pressing against the confines of the closet she was in, while her thighs ground and rubbed against each other in an attempt to quell the arousal streaming from her sex. Her tail stood raised on its own, exposing the head of the black crystal plug inside her ass, while her mane dropped over her naked shoulders in messy curls.

Outside of the closet, perfectly visible through the slightly ajar door Flurry was staring through, Princess Cadance lay naked on her bed. She was on her back, her wings splayed below her, her thighs spread. One of her hands pinched and twisted one of her ample breasts, while the other was on her sex, fingers plunging in and out of her cunt with reckless abandon as her palm rubbed against her clit. She moaned, but there was a shadow of yearning and dissatisfaction in her voice. It was evident in the desperate look of arousal on her face, in the way her mane lay strewn about and tangled, that the alicorn needed more.

Biting her lip, Cadance looked to the side, then her horn lit up. From below the bed, a box was lifted in the blue glow of her magic, and placed upon the covers where it opened with a click. Out came a dildo of plain black plastic, and Cadance reluctantly brought it to the entrance of her sex. She let go of it with her magic and grabbed it with her hand, then began to pump it in and out of her, the shaft easily sliding thanks to the copious amounts of fluids she was leaking. Her breath grew faster and heavier, but her expression remained coloured by that same need as before. Her eyes frantically raced over her own body, until finally with a shake of her head and a muffled moan she threw away the toy and took a bigger one from the box.

"See?" spoke a deep voice in Flurry's ear, and the mare had to bite down on her fist not to scream in ecstasy at the sound. "It's just like I told you. She can't take it anymore. All she needs is a final push, someone to show her just how good it would feel." Shadowy hands clawed at the Princess' flesh, rolling over her body and disappearing just a second later.

The young mare nodded frantically, still torturing her own nipple. "Yes, Master," she whispered out in breathy tones. Still watching her mother thrust the large toy inside herself, she waited for the right moment. Just as Cadance closed her eyes, Flurry silently stepped out of the closet and began to walk towards the bed.

Still panting and sweating, Cadance shook her head and reopened her eyes, clearly unsatisfied even by the new toy. It took her a moment to actually register Flurry's presence through the haze of her arousal, and one more to speak after the shock of seeing her daughter naked and clearly aroused. When she finally regained enough self-control to speak, she stammered out, "F-Flurry, wh-what are you- Ahhhhh..." Her words were cut off as the other alicorn pinched her nipples in her magic.

"Shh," Flurry replied, getting on to the bed. She placed a hand over one of Cadance's ample breasts, and straddled the mare, placing her knees just below her mother's wings. "I know it's hard. I know what the problem is. I'm here to help you."

"Flurry, what- Ohhhh," Cadance tried to protest, but was once again interrupted, this time by her daughter taking hold of the toy with her magic and beginning to thrust it inside her.

"You're having trouble cumming, aren't you?" Flurry asked, placing a finger over her mother's large lips to stop her from replying. "You've been having trouble with it for a while, right? Every day you wake up feeling a bit more horny, and you never manage to feel satisfied. I know all about it."

It was only natural that she would know. It was her fault, after all. While her connection to the Crystal Heart wasn't as strong as her mother's, it was still strong enough to corrupt it a little, and she'd been working on it for months, and preparing for years. Soon Cadance would see just how much better life could be when serving her Master, and the Empire would follow.

Cadance weakly struggled, but couldn't deny her daughter's words. "I... You shouldn't see me like this, this isn't- This isn't right!" she tried to protest through the thick curtain of foggy arousal clouding her brain.

"What's wrong with it?" Flurry teasingly asked, grabbing her mother's breasts and rubbing her thumbs over her nipples. "It doesn't feel wrong, does it?" She leaned down and planted a sloppy kiss on Cadance's lips.

The older alicorn was too overwhelmed with sensation to reply, and simply shook her head. It was all going too fast for her, she didn't have time to think things through, to focus on what exactly was happening.

"I know about the dreams you've been having," Flurry continued. "I've been having them too." Only half-true, to her they were visions her Master gave, and much more vivid. But then, every crystal mare in the empire had been having similar ones. "Don't you wish you could make those dreams reality? I can help you with that."

Cadance looked to the side. "Flurry, you should... Go away, I- Ahhhh... If only, if only Shining was he- Eeeeeeehhhh-"

But Shining wasn't there. He hadn't been there for more than a week, and he wouldn't be back for even more, not until his diplomatic mission to the Dragonlands was complete. They had chosen carefully when to enact their plan. Right when Cadance would be left alone with nothing but her toys to quell the insatiable heat they would put her through, and with no prospect of things getting better anytime soon. Not that Shining coming back would be a problem, if things went as planned.

"Would it really matter if daddy was here?" Flurry teased her mother, flicking one of her nipples. "You weren't even thinking about him anyway, were you?"

Cadance bit her lip, but instead of replying she looked to the side once again. Despite her efforts, her arousal was clearly getting the better of her, and clouding her senses just enough for her not to notice the subtle hits of green light in Flurry's eyes, or the barely visible tendrils of shadow crawling over her body.

Flurry lowered herself, crushing her own voluptuous chest against her mother's, and began to whisper seductively in Cadance's ear, while still thrusting the toy inside her. "You were thinking about those dreams, weren't you? Admit it. They just make you so so horny, you can't even get excited if you try to think about something else. Even when daddy was still here, you were already thinking about them while you had sex with him, weren't you?"

Flurry lifted herself and looked down at the other mare. Her eyes were glazed over with lust, and a line of drool fell from her half-open lips. There was a hint of guilt on her face, but her struggles to deny the way Flurry's words affected her were getting weaker and weaker. Her daughter pressed on, "That's right, isn't it? Those dreams are the only thing that can get you off anymore. Dreams of a strong stallion who comes from the shadows to take you and make whatever he wants of you. You dream of being his slave, his plaything, you dream of being used."

Cadance gave a deep, throaty moan, and Flurry continued. "But dreams are not enough. You need to feel it. You need to live it. You lie and tell yourself that things would be different if Shining was here, that you just have to hold on. But we both know that isn't true. We both know you'd already realised how he wasn't enough for you before he left, how already you were having trouble cumming, how you needed to think about those dreams to feel anything while he held you. We both know he can't satisfy you, not anymore, not after you've had a taste of what real pleasure is like. You can wait for him if you want, but he will never give you what you need."

Cadance tensed, and a look of terror overtook her face, giving her the appearance of a doe petrified by fear. Poor thing. She hadn't had an orgasm in days, and the prospect of never getting to feel one again terrified her, especially with the way her arousal had been rising in the previous days. She was stuck there, kept unnaturally horny by her connection to the Crystal Heart and to the hints of corruption Flurry had planted in it, kept on the edge of orgasm by her daughter's teasing, and yet permanently unable to satisfy the burning need inside her. She was just as they needed her to be.

"But I can help you," said Flurry, in a tone so sweet it may as well have been coated in honey. She lovingly stroked her mother's cheek, while her other hand began to pump two fingers in and out of her own sex at the sight of the thin black tentacles that began to crawl along it, unseen to Cadance. The green glow in her eyes intensified, as the other's gaze snapped towards her in a desperate cry for help, a desperate need to be released from her prison of ecstasy and denial. "I can give you what you need. Don't you want that, mommy?"

Something wasn't quite right, Cadance could tell, but it was becoming harder and harder to care about it. She was so horny, so desperate for release. What harm was there in listening to what her daughter had to say? Her daughter, her daughter who was plunging a toy in and out of her cunt and making her feel so good and- "Ahhhhhhhh," Cadance broke out in a moan, still staring at Flurry. She couldn't think straight, couldn't possibly control herself in that state. She needed to cum. She needed to cum and that was all she could think about. Frantically, she nodded her assent.

"That's right mommy," Flurry answered, moaning into her words as her nethers clamped around her fingers. "It's going to feel so good, mommy. Think about those dreams you had," she continued. The shadowy tendrils moved from her arm to Cadance's head, entering through her mouth, eyes, ears and horn. "Think about how good you felt in those dreams. So good. So good you could just let go of everything else, so good that you would want to be like that forever. It felt better than everything. Nothing matters more than that."

"Nothing else matters," Cadance muttered out, barely aware that she'd even spoken. Her head was foggy, and it was getting hard to think. It was so much easier to just listen. Listen to her daughter, listen to the voice in her head. They said it would feel good. She wanted to feel good. She needed to feel good. Feeling good was all that mattered. A subtle green light began to shine in her eyes.

"That's right," Flurry continued, arching her back as she furiously masturbated over her mother's body. "That's right, mommy. You want to feel good. You want those dreams to be real. There's a way to make them real, and you can do it. All you need to do is listen to me, and I'll tell you what to do. You want that, right, mommy?" The green light in her eyes shone brighter, and drool began to leak from her mouth. The tips of her nipples rubbed against her mother's, as she swayed her heavy breasts back and forth.

Cadance just nodded, unable to let anything other than moans leave her mouth. It felt like a dream, like none of it was real. One more of those dreams she'd been having, the ones that had her wake up to a puddle of drool on her pillow and her fingers jammed in her cunt. Just like that. Her own daughter fucking her, and then her Master would come for her, and make her feel so good. She just had to go along with it. She just had to feel good.

Flurry bit down on her lips to hold in a scream, as clawed hands of pure shadow wrapped around her breasts and pinched her nipples. "She's ours now," her Master's voice spoke in her ear. "She'll do anything we tell her to. It's time."

Flurry was left a panting, sweaty mess, a stream of arousal leaking down her thighs. She looked down at her mother, and moaned as she saw her empty gaze. She'd waited so long, so long for that day. For years, after her Master had found her. And now he would finally return. He would finally take her as his, finally give her that pleasure she'd been dreaming of ever since she'd devoted herself to him. Finally the whole Empire would know what their true purpose was. Already, the connection between Cadance and the Heart was affecting it, she could feel it. It only made her more horny, more eager to finally feel her Master's touch.

With agonizing difficulty, the alicorn pulled herself away from her mother's body and stood up. "C-Come with me," she said, removing the dildo from Cadance's dripping wet sex.

Spurred by the sudden emptiness inside her, Cadance stood up on wobbly legs, and began to finger herself as she walked behind her daughter. It was all so surreal, it couldn't possibly be the truth. The voice in her head told her not to worry. The voice told her she just had to feel good. She liked feeling good. They walked out of the room and into the corridor, both naked, both masturbating. From her position she could see Flurry's plug behind her raised tail. Her daughter was such a slut, and it turned her on so much. There was no need to worry about anything. It was like a dream, and all that mattered was feeling good.

They passed by other crystal ponies on their way to their destination, all clearly aroused. At the sight of her, a maid completely lost control and began to plunge her duster in and out of her nethers, howling in pleasure. Another maid they found bent over a table, her skirt raised over her back, as a guard railed her from behind and another took her mouth. How had she not seen it before? This was what her subjects wanted as well. To feel good. To feel pleasure. Only pleasure mattered, nothing else.

The two finally arrived at the bottom of the palace, and stepped out into the streets of the Empire. The Crystal Heart was in front of them, and Flurry stepped up to it, standing at its side as she turned back to her mother. There was a hint of something else in the polished crystal. Like a worm, or an insect, something dark wriggling inside it. A sliver of corruption gnawing at the magic artefact, slowly feeding on its power and corrupting its essence. And at Flurry's side stood a shadow, barely visible in the light of day. Cadance's own heart almost stopped as she saw it.

She knew what she needed to do, even without the voice in her head reminding her about it. She stepped forward on shaky legs, still vigorously masturbating, as a line of drool leaked from the corner of her mouth. Her dreams would come true. All of them. He would come for her, and she would feel so good. Somewhere deep inside her mind, buried under the mountain of lust and pent-up arousal filling her thoughts, she distantly decided it really had to be all a dream. It couldn't possibly be real. So what she was about to do didn't matter. All that mattered was how good she would feel afterwards.

What was she even doing, exactly? The spell flowing from her horn wasn't one she'd ever studied or read about. Yet her body perfectly knew what to do. Just like a dream, she just had to watch herself play her part. Power flowed from her and around the Crystal Heart, and the jewel began to darken, as deep purple mist started to rise around it. It was a dark spell, one she wouldn't have found in any but the most closely guarded of archives. It hurt a little, to use it. But she was too distant, she didn't feel the pain, only know it was there.

She felt a part of herself change, shift in unnatural ways. Some deep and intimate aspect of her nature being twisted. The same was happening to the Heart. What had been much like a worm inside it grew, and expanded. It mutated into something greater, stronger. Something that slowly began to overtake the Heart itself. Like a spider, crawling inside the crystal and eating away at it, changing it, repurposing it. Making it into something else as it took control of it. The bright light-blue turned to black and red and purple, as piece by piece the thing inside the Heart became the Heart itself.

The purple mist around the altar swirled and darkened, obscuring the Crystal Heart. Cadance fell to her knees, and a dry scream came from her throat. Pain and pleasure both coursed through her body, too great for her to process in her barely aware state. Her frame was wracked by violent shivers, and tears involuntary began to stream down her face as she stared at the expanding mass of black mist and shadow in front of her. Still plunging her fingers into her sex, while her other hand toyed with her nipples, she threw one look at her daughter, who was masturbating just as vigorously and throwing her head back in pleasure. Then everything went white in her mind, and she passed out for a moment.

A second later, the pink alicorn came back to her senses. She felt like she was about to vomit. She was shivering, cold and sweaty, her horn ached and her head pulsed. Her muscles hurt like they'd been strained, and a bitter aftertaste was left in her mouth. She pushed herself up from the cold crystal floor, realising she was naked, and covering herself up with her wings she stared towards the Heart. An avalanche of sensations and memories hit her mind, and she almost threw up, falling back to her knees. She was slowly realising what she'd done, and was both disgusted in herself and furious towards the one responsible for it.

In the mass of black mist below the tower, covering the altar where the Crystal Heart had been, a silhouette began to take form. As the darkness condensed more and more, he stepped forward, letting the residual shadow form into a mantle behind him. He was naked except for that, and on his chest could be seen the blackened, hardened and corrupted crystal which had once protected the Empire from him. His body seemed to be made out of chiselled stone, his muscles powerful and defined, and energy crackled around his horn.

He appeared to radiate a softly glowing aura of dark power with his mere presence, and Flurry dropped to her knees as she saw him, worshipfully kissing his hooves and sticking her ass in the air, her tail lifted to expose her nethers. His piercing eyes studied the place, then set on Cadance. He smiled, baring his fangs, and began to advance towards the alicorn still lying on the ground, while her daughter trailed behind him and licked the ground he walked on. "It's been a while, hasn't it?" he growled in a deep tone.

Just in that moment, a group of four guards arrived through the palace's door, two mares and two stallions. They seemed relatively aware of their condition, if a little messy, and had probably been waked out of their trance by the sudden magic impulse in the same way Cadance had. Sombra just smirked and rolled his eyes at the sight, equally amused and annoyed. The stallions charged forward, but their spears shattered and splintered into red sparks before they even touched the unicorn. With a flick of his horn, he knocked them out cold.

Then he focused on the mares. One single look was then enough to have them fall on their knees, moaning as they fingered themselves, their eyes glowing green. In seconds the two had thrown away their armour, and were clawing at each other's clothes, exchanging sloppy kisses and grinding their nethers against each other. One had taken her sword and started to rub the pommel over her sex, after using the blade to cut off her underwear, while the other was pinching and biting her own nipples.

Turmoil raged in Cadance's mind at the sight. She was disgusted with herself, with what her daughter and her subjects were being made to do, and with the monster who was behind it all. Ashamed of having fallen for his trick, worried about the safety of her ponies, and deeply horrified at what Flurry had been turned into. And she was angry. She was furious, and the rage consuming her pushed everything else to the back of her mind. The only thought she had was that of stopping Sombra. "You worm!" she hissed back towards the unicorn, preparing her magic as she stood to face him.

Sombra clicked his tongue in disappointment. "Oh, Cadance, Cadance. That's not how you welcome your King at all. Why can't you be a bit more like your daughter, huh?" He looked back for a moment and pressed a hoof over Flurry's head, forcing her face against the ground and making her squeal in ecstasy. "See?" he asked, turning back to Cadance. "Now that's proper behaviour when dealing with your better. You should learn from her." He returned to walking towards the pink alicorn. "You know, I really have to thank Flurry. It's thanks to her if I'm back."

A part of Cadance wanted to ask Sombra what precisely he'd done to her daughter, or to the Heart. A much bigger one simply wanted to blast him as hard as possible. She could always ask questions once she had him beaten and on the ground, and if she ended up destroying him it wouldn't be a big loss. She adjusted her position slightly, studying her opponent as he moved closer to her. The risk of damaging the Heart was there, but it was worth taking, and the Crystal could be repaired. She needed to be careful though, she'd just exerted herself with his spell and was still tired by it.

Sombra smiled, running his eyes over the curves of her body, hidden behind her wings. "Well? Are you going to shoot or not?" he asked in mocking tones. Still moving forward, he continued, "Not that it would matter. You're a fool if you think you can hurt me now, Cadance." He was at a short distance from her, and finally he stopped. "But if you're really determined to do it, go right ahead, you have a free shot." He opened his arms and stood still in front of the mare.

Cadance bit her lip. Was he planning something? He must have been. Or was he really that confident in himself? That wouldn't have been out of character for him, either. He couldn't possibly be strong enough to actually survive an attack from her, could he? She found herself looking at his body, studying him and trying to determine if he really could have become strong enough. That aura of power around him, those bulging muscles, those perfectly defined abs, that regal and imposing posture and-

"Something the matter?" Sombra asked with a smile.

Cadance jolted at attention, like a misstep in a dream had woken her up again. She must have been more tired by the spell than she'd realised, and... Was that drool running from her mouth? She brought a hand to her cheek and promptly sealed her lips. What was happening to her? She couldn't get distracted, not by Sombra's deep eyes or by his beautifully curved horn, or by Flurry kneeling beside him like a good whore, or by the impressive length of the shaft she lustfully eyed, so big and thick and-

Sombra took a step forward. "Are you having trouble focusing, dear?"

Cadance heart jumped and she fell to her knees. Her nethers were throbbing, dripping with arousal. She brought a hand to her forehead, trying to stop the world from spinning all around her. Where was she? What was happening? There was that stallion, the one from her dreams, and she was naked. He was going to take her, and fuck her, and make her feel so good... Flurry was there- He would fuck her too! He was- He was Sombra, she had to stop him, she had to...

The pink alicorn looked up, running her eyes on the black unicorn standing over her. His muscles gleamed in the light, and the blackened crystal on his chest radiated power. He'd corrupted her daughter. He'd twisted her mind, and made her into a whore. He'd tainted the Crystal Heart, and used her connection to it to infiltrate her mind. He'd brought dreams of lust and submission to all ponies in the Empire, filled them with desire that couldn't be quelled to manipulate them. He'd come to her in her weakness, manipulated her, and used her to return fully among the living. He was a monster.

But he was there now. The stallion she'd dreamed of for so long, even if he'd been the one to make her dream of him. He was so strong, so powerful. So beautiful. She'd submitted so many times to him in her dreams. It always felt so good. It would feel even better. Desire was burning inside her, impossible to ignore. All the memories of her visions returned to her, more clear, more defined. It was always Sombra, always him, taking her, dominating her. She had to submit to him, she had to give in. Her mind told her that. Her body told her that. Her very being told her that.

But no! No no no! She wouldn't fall like that, she wouldn't allow him to win like that. She couldn't allow it! No matter what he'd done, no matter what she felt. It was not how things were meant to be, and she wouldn't submit to him. Gritting her teeth, Cadance began to once more gather up her magic in her horn. It didn't matter if she wasn't strong enough, it didn't matter if her body tried to betray her. She would not give in! She wouldn't surrender to the monster who'd done that to her daughter. She was better than that.

Sombra lowered himself, and looked at the alicorn's eyes. He took in all her hatred, all her will to still defy him despite all he'd done to take control of her. All the determination the Princess still showed, even after being humiliated so far. And it didn't matter. He cupped her chin, forcefully holding her mouth closed, and slowly turned her a bit to the side. He moved his mouth to her ear, and breathed in it, almost whispering something. A thread of deep black smoke slithered out of his mouth and into Cadance's head, and a moment later clouds of it billowed out from the alicorn's mouth, eyes, nose and ears.

Something inside Cadance broke. Her magic fizzled away, and she slowly turned back towards Sombra as he stood back up. Her eyes roamed over his perfect body, the most beautiful thing she'd ever seen. What had she been thinking? She'd been so foolish, so absurdly wrong in thinking she could ever oppose a God like him. But now she saw the truth. All the resistance inside her had been made to wither away, and it allowed her to finally comprehend how utterly magnificent her King was. How wonderfully perfect it was to be his.

Still kneeling, the mare inched forward, hesitantly extending an arm towards the unicorn's thigh. He took another step forward, and forced her to touch him. Despite being startled by his motion, she did not draw back, and instead began to run her hand over his muscled leg. His shaft was mere inches from her face, and its smell began to enter her nose. Unable to stop herself, the motion almost instinctual at that point, she dove forward and began to run her tongue over its length. The taste was delicious, and she started to lap up more and more, using a hand to bring his tip up to her lips and wrapping them around it.

Submission had become ingrained in her after countless nights going through the same dreams, and even without her utter and willing submission she couldn't have fought against her body's reflexes anymore, not to mention how her very soul was being tainted by its connection to the Heart. Carnal submission to Sombra was a part of her own nature at that point, one she could no longer hold off. She needed to serve the unicorn, to please him. Sex and obedience were replacing everything else in her mind. Her dreams were becoming her truth. She was the horny slut ready to serve her Master's every desire, it was her very purpose to please him.

Softly pushing her plump lips around the top of Sombra's hardening shaft, she started to bob her head back and forth, tasting the first drops of his arousal on her tongue. She moved faster and faster, trying to take him deeper and deeper. As the unicorn's cock hit the back of her throat, she began to gag, and struggled to push through. So she looked up at her King with pleading eyes, still running her tongue on the underside of his member and whorishly stretching her lips forward in an attempt to take as much of him as she could inside her mouth.

Understanding her request, Sombra lowered his hands to her. One wrapped around her horn, while the other pressed against the back of her head. With one swift, strong push of his muscled arms, he drove her forward and pushed his cock into her throat up to the hilt, letting her face press against his crotch. Cadance let out a sound that should have likely been a moan, gargled and warped by the hunk of flesh filling her throat. As spit, drool and precum dribbled down from both her nose and the corners of her mouth, she smiled and began to fondle the King's large balls with a hand, lustfully stroking his muscled thigh with the other.

Sombra held the alicorn there for a few seconds, simply moving her back and forth a short amount and listening at the gurgling sounds of her obstructed throat. One of her hands had left his thigh and plunged into her nethers, while the other was still massaging his testicles, moving between one and the other as they were too big for her to hold both together. One alone already more than filled her delicate palm, and she very carefully scratched their taut skin with her long, polished nails, clearly dreaming about the contents those balls would unleash inside her.

With a smirk and a sudden push, the unicorn threw Cadance forward, separating her from his shaft and making her land on her back. He stepped forward, and before she had a chance to move placed a hoof over her neck, forcing her down. Staring at her eyes, filled with lust and desire, he pulled back his leg and knelt in front of her, holding her down with his magic instead. He placed his cock over the entrance to her sex, rubbing it back and forth, and spanked her tits with the back of his hand. "Do you want this, slut?"

Cadance's whole body was on fire. Her marehood was burning with arousal as Sombra teased it with his member, her skin stung in delightful pain where the unicorn had hit her, and her thighs quivered with uncontrollable arousal. She was breathing hard, her cheeks were flushed, and the only reason her wings weren't fully opened and stiff was because Sombra was holding them still with his magic. The taste of his sex still lingered in her mouth, leaving it a salivating, buzzing mess, and her brain was only focused enough for her to nod her agreement towards him.

Sombra didn't wait for any further invitation, not that he would have waited anyway. In a second, he lifted the mare's legs to rest one of her hooves over each of his shoulders, giving a slap to her full ass in the process, then dove forward. As her legs slid up his shoulders, leading her knees to hook on them, the head of his cock spread the alicorn's nethers wide open as he drove it into her all the way to the base. He remained there for a moment, enjoying the sensation of the alicorn's marehood around his new body, and stared right into her eyes.

A chocked cry left Cadance's lips, and she lifted her arms towards the unicorn's to try to bring him even deeper inside her, doing the same with her legs as far as she was able to. Her mind was in shambles, unable to process anything beside how good she was feeling. How right everything felt. It was like finding what her cutie mark had been. It was like finding her purpose anew, like she was finally doing what she was supposed to. She'd spent so many nights dreaming of Sombra taking her like that, so many hours of her days trying to replicate it and always coming short. And now that the Crystal Heart was Sombra's, so was she. It was her purpose.

And then Sombra began to thrust. If Cadance had had trouble focusing a moment before, it became downright impossible the second he did. Her whole world was swept away, and all her attention focused on the single point between her legs, where her King's shaft restlessly plunged in and out of her at blinding speed and with a strength that would have broken a lesser pony's bones. Every time Sombra's cock entered her her insides were spread wider than ever before again, and in a few thrusts her ass had turned red from the impacts with the unicorn's body.

The unicorn kept her pressed down, and moved his mouth over her neck. He bit down on it, passionately but not hard enough to pierce her skin, then moved higher and did the same with her lips. The red and plump pillows of flesh were caught and toyed with by his fangs, before he forced them open and plunged his tongue between them, dominating hers. His curved horn slid against Cadance's straight and spiralling one, sending red sparks flying through the air and lighting a fire in the alicorn's mind. His hands moved to her wings and began to knead through them, making the mare moan into his kiss.

Every time Sombra's cock hit the deepest parts of her Cadance's whole body quivered, and her nipples stood painfully stiff. Sweat ran down her breasts and back and thighs, and drool coated her neck and chin, dripping from the corners of her mouth as her sloppy, slobbering kiss with the unicorn continued on. Her eyes almost rolled back into her head, and she only fought back against it so she could see more of her King's perfect new body. He was a spectacle to behold, so magnificent the mere sight of it could make a mare shake with lust and desire. And he owned her, mind, body and soul.

Sombra's mouth left hers, and his thrusts became less frequent, though faster and even stronger than before. As he pulled back, Cadance got a chance to look at herself, and noticed how the bulge his shaft made in her whenever he pushed forward was visible even behind the heavy slopes of her breasts. She bit her lower lip and moaned at the realisation, spraying her juices over his thighs. She could feel his cock throbbing inside her, slowly growing hotter as its head began to flare out. With a howl of pleasure, she searched for his eyes and begged, "Cum inside your whore, please, my King!"

Sombra moved his hands to her neck, trapping her legs between his chest and his elbows. He began to choke her, right below her chin, as his thrusts became even less frequent and even stronger. The crystalline ground below them began to crack under the intensity of his motions, and the entire underside of Cadance's thighs was soon as red as his horn. "Do you want it, bitch?" he asked, baring his fangs, and when the alicorn's reply came as frantic nods and chocked sounds from her throat he slammed into her one last time, hilting his shaft in her insides and creating a small crater below them with the impact.

Cadance threw her head back, as far as Sombra's grip allowed her to, and let out a garbled sound that would have been a scream of ecstasy had she been able to breathe. Despite the lack of air, the unicorn's thrusts had easily kept her awareness intact, each one a new shot of sensations pumped directly in her veins. The last ones had almost knocked her out though, she'd never experienced something so strong during sex. Never something so rough, so amazing. She'd been spraying her orgasms over Sombra's chest for a while, and yet her climax didn't seem to end.

Then, finally, as he rammed inside her one last time with enough power to shatter the ground around them and make it collapse, Sombra began to cum. It felt like nothing she'd ever experienced before. It was beyond simple physical pleasure. It was like the happiness she felt when she used her talent to mend relationships between ponies, only a thousand times stronger and more intense. A blissful, mind-wiping feeling of belonging, of righteousness. Like she needed nothing else, like she had no desire for anything more. Like she'd found her true purpose, her true place in the world.

Not to say that there wasn't any physical pleasure involved. All the pent up arousal of weeks of denied release was flaring out in her mind, all at once. On top of that, Sombra was nothing like any mortal stallion or mare she'd ever bedded, Shining came nowhere close and not even the magically enhanced cocks she'd had inside her in her life could compare. His seed was like fire spreading inside her, like smoke forcing its way into her very being, worming its way into her body and changing her further. She felt it in her womb, she felt it in her breasts, she felt it in her heart and coursing through her veins.

She didn't know anymore if she'd had any sort of seals against pregnancy before. If they'd deactivated once the spell had drained her, if she'd turned them off without realising it, if they were still up. It didn't matter at all. If the unicorn cumming inside her wanted her pregnant, no magic force or spell would possibly oppose him. It was all up to whether he wanted it or not then, and she was perfectly happy with it. Her body was his property, and he had the right to let her carry his lineage if he wished.

With a deep, long sigh, Sombra let go of the alicorn's throat and slowly pulled back, though he kept her legs pressed against her shoulders. He stood and took a step back, looking over Cadance's dishevelled state, and smiled to himself. Then he turned his head back, and gave a nod. "Come here, pet. You did a good job, and it's time for your reward." As Flurry crawled to be in front of him, he grabbed hold of her mane and shoved his still hard cock down her eager mouth, then slowly pulled back, letting her clean his shaft of his and her mother's juices as she pressed her lips around it.

Once her mouth left her Master's cock, Flurry's head was turned and thrown forward, bringing her face only inches from Cadance's nethers. Meanwhile, on her backside, she lifted her large, jiggling ass up like a good slut, to give her King easy access to her holes. Face down and ass up, her large breasts crushed against the cold crystal floor, the younger alicorn let the smell of sex coming from her mother's abused marehood drift up to her nose, and quickly began to copiously leak her own arousal from both sets of lips, as her eyes rolled back and a moan escaped her throat.

Sombra slapped his hand against the white mare's ample behind, with enough strength to peel away the skin of a normal pony, and watched her flesh ripple with a smirk as a reddened imprint appeared where he'd struck her. Fully moving her tail out of the way, he plunged a couple of fingers in her dripping wet sex, then removed them and began to draw circles around the entrance of her ass with a claw. Forcing the alicorn's stiffened wings against her back with his magic, to get a good look at both her and her mother, he said, "Feel free to eat what's left of my cum out of her."

Cadance had been slowly coming back to her senses, and the first true sign of her being aware again was the yell of pleasure that left her lips once she felt her daughter's tongue digging into her folds. She looked down to see Flurry bent over, licking her sex, while Sombra stood behind her, dragging his shaft back and forth over his first pet's marehood, and a gush of juices sprayed from her nethers onto her daughter's face at the sight. Cadance chose to simply hold her legs against her shoulders, lifted and spread, as she lost herself to the pleasure of her own child digging into her pussy to lick out more of their Master's cum.

Sombra looked once more over Cadance's body. The red, stinging marks of his hands on her neck and of his thighs on hers still gleamed in the light, and her face was twisted into a mask of pleasure. Satisfied, he returned to focusing on the younger alicorn. He took hold of her black crystal buttplug, still stroking the top of his cock against her sex, and pulled it out of her. Once the still relatively long, vaguely egg-shaped jewel was outside her, it morphed in his hand into a larger, longer shaft, with something resembling a hook near the base. After taking a look at it, the unicorn wasted no time and shoved it into Flurry's marehood, letting the protruding piece stick out to rest against her clit.

He paid no heed to the howls of pleasure the mare let out as he did so, nor to the even louder screams of bliss that left her once the newly enhanced toy began to vibrate and crackle with magic, sending sparks of energy into her nethers and clitoris. Instead, he simply pulled his shaft back, gave another loud smack against Flurry's jiggling ass, and lined himself up to push his cock into her remaining hole. With a small, tentative push, the head of his stallionhood found its way into the mare's magically lubricated and eagerly awaiting hole, and a moment later he slammed fully into her, sending her moans to an even higher pitch.

Seconds later, he was thrusting into her with the same pace and intensity he'd had while fucking her mother. The flesh of her ass rippled with each slam of his hips, and her thighs quickly reddened under the strength of the impacts. Flurry's face was pressed against Cadance's cum-soaked pussy, as she became unable to keep eating her out and barely managed to hold herself up with her arms. The younger alicorn moaned into her mother's sex, and the elder moaned back at the sight of her daughter being fucked like that. Then, Flurry's head was pulled back and her back forced to arch, as Sombra took hold of her mane.

Repeatedly slamming into his slave's ass, the unicorn continued to slap and spank her quickly reddening backside with a hand, while he gathered her mane in the other and pulled back on it. Flurry was left resting more on her chest and tits than on her arms, as her hooves left the ground with every thrust of Sombra's hips, the only thing truly holding her up being his shaft speared inside her. Sombra ran his eyes over the white alicorn's body with a delighted smirk, occasionally throwing a glance at her mother fingering her pussy as well.

Flurry's eyes rolled back into her head and drool leaked past her pillowy lips onto her heavy tits. Between the magic stimulation of the toy in her cunt sending her senses haywire and Sombra's large, throbbing cock plunging into her ass she'd been practically cumming non-stop for minutes, spraying jets of her arousal down her thighs. The smell and taste of sex on Cadance's body didn't help in the least, and only made her brain fog up with more lust. And what little she'd gotten to eat of Sombra's cum had made her desperate for more, the thick black strands had set her tongue on fire and made her throat feel like it was the inside of her sex.

That was what she'd been moulded into, over years and years. It had become her purpose, her true nature. Even her cutie mark, marking her connection with the Crystal Heart, had been nothing but the consequence of Sombra's wonderful plan for her. He'd found her, when she was still young and he was still weak. And he'd shown her how wonderful the world could be under his control. From that moment, all her life she'd been training, reshaping herself both mentally and physically to serve her King, to aid in his return and be his worshipful, eager and obedient toy afterwards.

The magic she'd used on herself would have disgusted and terrified her parents had they known about it. Sombra had created it himself to better the slaves under his control, and she'd been exposed to it ever since her young age. Moulded through the course of her whole life into being the perfect fucktoy for her King. Her tits, her ass, her lips, her face, her mouth, her thighs, her waist, her legs, every part of her had been infused with magic, twisted and modified to serve no purpose other than serving Sombra's pleasure. And finally, finally she was allowed to carry out what had become the sole reason for her existence.

Sombra suddenly let go of the alicorn's mane, letting her head fall back forward. He grabbed her thighs with both hands, and lifted her back up in the air, then began to pound harder and faster into her ass. The head of his shaft began to flare, and Flurry once more screamed in pleasure as her face was pressed into her mother's nethers. With a shift of his hips and a pull from his arms, Sombra brought the mare to rest vertically over his cock, her wings pressed against his chest. His arms hooked below her knees, his hands met behind her neck, and he held her there as he thrust his cock upwards into her.

Cadance, violently fingering herself and roughly toying with one of her nipples, watched the scene before her with shameless arousal. Flurry's body was a display of depravity, fully exposed. Her face was a distorted mask of pleasure, her mouth half open in a moan leaking drool past her plump lips and onto her huge bouncing breasts. Her thick thighs were spread wide, and the bulge the giant dildo plunged into her created on her belly was evident, along with the constant jets of liquid arousal she shot out from her sex.

Sombra kept thrusting into the mare, as his large balls flapped up and down with each jerk of his hips. His cock flared to its full size, and he kept plunging in and out of her as shot after shot of cum began to spray into her. He'd magically perverted her body and her holes to be always tight, but never too much so, and it was exactly as wonderful as he'd hoped it would be. Flurry was without a doubt his greatest achievement besides himself, and now that he'd come back he'd get to twist and pump her body full of dark magic even further.

As the unicorn pulled out of her, he let go of Flurry, and she fell forward on the ground. The last shots of his cum landed on her back, and the black droplets seeped into her flesh, burning what felt like holes in her body and making her cry out in pleasure again. She slowly got up, as her insides absorbed the considerable load Sombra had ejaculated inside her, spreading that same blissfully burning sensation through her back and belly. Then she fell to her knees and scream once more, feeling the familiar sting of her King's power piercing her flesh and twisting her body.

Sombra began to walk away back into the palace, while the shadows around him morphed into a regal set of clothes, black and crimson red with fur trimmings and silver linings. Flurry stood up behind him on shaky legs, still struggling against the pleasure the toy inside her marehood brought her, and began to follow, though she shortly after fell to her knees and chose to simply keep crawling. Cadance chose to do the same, getting on all fours behind her and fingering herself to the sight of her daughter's abused nethers as she went on.

If anyone noticed how the pink alicorn's cutie mark had switched to a red and black colour scheme, no one made mention of it. Not the naked mares joining the line of slaves crawling behind Sombra, not the guards kneeling at his passage and bowing their heads low. If any of them still had some resistance left, it was gone by the time their King reached them. The doors to the throne room opened wide as they welcomed the stallion who'd twice before claimed the place as his own, if only briefly the second time, and black crystals sprouted all around the room at his passage.

Sombra sat down on his throne, and Flurry knelt at his side, a hazy and lust-dazed look on her eyes. He scanned the room, and the many mares looking up at him in adoration as they fingered themselves and toyed with their breasts. Then his gaze set on the one before him, offering her old crown and staring at him with pure worship in her eyes. With a smirk, the unicorn took the crown and crushed it within his fist. As a new one formed on his head out of the shadows surrounding him, the piece of metal in his palm twisted and bent into a thin circular strap, with a now bright red gem in the middle.

Cadance saw it, and she understood. Trembling with excitement, she pulled back her mane and pushed forward her neck, the signs left by Sombra's hands still visible on it. The collar clicked around her throat, not too tight but still enough for her to notice it, then her King cupped her chin and made her look up at him. He was perfect, the most beautiful creature she'd ever seen. The most powerful pony she'd ever met. Magnificent, and worthy to rule over her. It filled her with joy to know herself his property.

She looked at her daughter, cumming her brains out at his side. She had much to thank her for. And she was such a beautiful creature, oh how she hoped her King would twist her own body like he'd perfected hers. Then, she was made to turn and stare at the assembly of adoring mares in the room, all playing with themselves and moaning in bliss. With a wide smile on her lips, the alicorn bent forward, and lifted her heart-shaped ass up in the air. "Please," she begged, "I am worthless before you, but please, use your slave's body as you desire, my King."

Author's Note

If that part made someone uncomfortable, I do not believe Sombra did anything akin to sexual abuse or rape with Flurry when she was young. He was a shadow barely strong enough to whisper to her, he couldn't have either way. What and when he did is up to interpretation, but it was never my intention to give the impression that he fucked a child. I'll gladly expand on what exactly I think he did in the comments if asked.

Also, I'm planning a non-commissioned sequel to this about what exactly Shining was doing in his trip (spoilers: making it so it should be called her trip, for one). It won't come soon, I have JC and other commissions to work on, but it will come eventually. Force me to write it if it doesn't.
