Chapter 1

Shining Armour awoke, not on his comfy bed, not nuzzled in next to his loving wife. There was no smell of her sweet perfume or the comfort of her warmth. Instead, there was cold stone pressing into the stallions back, the cold stone of a granite slab that he was currently chained down to.

This was most certainly not where he had expected to wake up, but Shining Armour was a Captain, a Captain to the whole army of an empire to which his wife was Queen. He did not panic, fear did not set into his heart and begin to tear him apart.

Instead, he simply let out a soft little grumble, his muscle clad white frame suddenly pulling taunt against the chains that held him in place, seeing if he might be able to pull them free. His muscles flexed roughly and he let out a soft groan, but there was no shifting from the chains, they held tight and kept him tightly chained down.

As a captain, he had to be prepared to deal with things like this, he had expected at some point that he might end up awakening in a spot of bother, captured by an enemy of some kind.

Indeed, his first concerns were not for himself, but instead for his wife. He wanted to know if his wife was safe, as he had certainly gone to bed next to her last night, so not waking up next to her now was a serious concern.

If they had harmed his wife, he would most certainly cut down whoever had done this.

And he did not have to wait long to find out who it was that had carried out these actions against him, as a black robed figure stepped out in front of him. Shining Armours eyes quickly scanned the area around him, looking for anything that he might be able to use to get away.

It seemed that he was currently in a temple of some kind, a temple that he did not recognise in the slightest. Great sandstone pillars rose up to the roof, each of them covered in a number of brightly burning torches that sent flickering orange light dancing around the giant room.

There was a set of stone steps leading down to the granite slab he was currently chained to, and he would have liked to look behind him and see what was there, but that would involve taking his eyes off the black robed figure in front of him, and that would not be smart.

“Who are you, and what have you done with my wife, monster?” He asked. Already questions were buzzing through his head. Who could it be? The changelings? He had fought those foul creatures many times before and they had been wiped out!

Besides them, he could not think of anyone else that would take the time and effort to kidnap him, most of the empire’s other foes would just have killed him in his sleep without worrying about taking him hostage.

The robed figure let out a soft titter from beneath the hood, then threw it backwards to reveal the mulberry fur and two toned mane beneath. It was…

His sister? Twilight Sparkle, Alicorn and future Queen to all of Equestria?

What in Tartarus? The look of confusion on his face must have been easily read, as Twilight let out another soft laugh, a hoof moving up to the mask of a bird she was currently wearing, pressing it up against her mouth as if she was trying to silence her laughter.

The mask only covered the top half of her face, letting her muzzle poke free from beneath it, but wrapping the top half of it in a really long beak that seemed to be based off a crow or other animal.

“Sorry for laughing, Shiny. Your face was priceless and I could just not help but laugh, I’ve never seen you look this helpless before!”

Shining Armour was not happy, and he tried to make this clear by letting a deep frown spread across his face, earning more tittering from Twilight.

“What the hell is going on, let me go this instant! Is Cadance in on this? It’s not funny!” He spluttered, trying his best to keep calm, although if he was being honest this had been quite a scary experience and he could not believe that his sister would do this to him.

“What? Of course Cadance is in on this, she’s right behind you! And I can’t let you up, the chains are there to stop you struggling!”

Shining Armour’s head was spinning at this point, confusion tearing through him as he tried his best to see behind him.

His wife, the bright pink alicorn that he had fallen so deeply in love with, was currently leaned against the inside of a bronze circular bathtub built into the floor, sipping softly at a glass of champagne. Upon seeing her husband was looking at her, she gave him a wide smile and waved a hoof.

“Hey Shiny, surprise!”

Anger flared through Shining Armour, who tried his best to keep his voice calm as he spoke “What in… the ever living fuck is going on here? Why am I chained down?”

Twilight laughed softly “Surely you know, you married Cadance, did you not? Did you not read the conditions for your marriage?”

This did not help Shining calm down in the slightest, and he let out another grumble as he straightened up and attempted to pull away from the chains “What fucking conditions? Let me up, this is not funny any more!” He roared, really not happy with the situation any more.

It was Cadence's turn to laugh now “Don’t worry, he’s always like this before he had his first cup of coffee.”

Why was nobody else taking this seriously, he was really starting to get pissed offf off now. He was going to need to have a word with Cadance when he got out of this situation.

Twilight let out a soft sigh, then pulled out a paper from beneath her robe and pulled it open “You did not even read your marriage certificate did you?” She gently moved a hoof down the paper, stopping once she got about half way down the paper, licking her lips softly before speaking calmly.

“Right here, paragraph six, line four:
Upon signing this paper, the party will be married to Cadance until they produce an heir. Upon this condition being met, the marrying party (The husband) may be sacrificed to the Princess of Love, AKA, Princess Cadance.”

Shining armour blinked softly.
“What the fuck. I-I That’s bullshit, what the fuck is this? It’s not funny, let me go!”

Twilight shook her head slowly “Nobody ever reads the small print, it really is amazing.”

Cadance let out a soft sigh as she leaned back against her tub and took another sip of her champagne.
“Can we get on with this, my tub needs more blood in it, it’s really starting to get cold.”
Twilight giggled happily and took out what appeared to be a sacrificial dagger, which was ornately decorated with gold engravings, moving towards Shining with a sadistic grin etched onto her face as she slowly climbed onto the stone slab to stand over Shining, leering down at him.

Shining Armour had reached his limit by this point. This had gone well beyond a joke and he begin to tug and struggle frantically against the chains that were holding him down in a desperate attempt to get away, an attempt that ultimately proved fruitless as they seemed to pull taunter against him, binding him tightly against the cold granite of the slab and leaving him helpless to the dagger that Twilight was now raising high above his head, preparing to plunge straight down into his chest.

“No! Stop, this is not funny!” Shining cried.

Twilight sighed, shaking her head sadly “You’re right, it is not funny. Cadance needs her ration of blood or she starts to shrivel up like a raisin, blood for the blood god and all that stuff.”

Shining’s head spun, he desperately attempted to form words, but the only one that managed to make it passed his lips was a half hearted “What?”, his head spinning as he tried desperately to comprehend what it was that was currently happening to him.

Twilight let out a growl at this point, taking off her mask for a moment to rub at the gap between her eyes in an attempt to remove all the tension that had built up there.

“Don’t you know anything about your wife? You do know she is not a proper Alicorn, right? And you honestly think that someone with a body like her has not got married before?”

“Wha-” Shining babbled, unable to come up with anything more intelligent to add to his speech. Non of this made the slightest lick of sense to him, and he had come to the conclusion that this had to be some kind of nightmare. That was the only way any of this made the slightest lick of sense.

“Celestia, I feel like I’m explaining this to a child. Your wife is a succubus! A fucking sex demon! What else did you expect the Princess of love to be? And in order to not crumble to dust, every hundred years she goes on a rampage for a week, butchering stallions and mares with her sex demon powers in order to use their blood and souls to get thicc and young again.”

Shining Armour was done with this whole situation, he let out a growl and begin to desperately try and pull himself free from the stone slab. It did not work as the chains were far too strong, refusing to budge in the slightest even when faced with his considerable strength!

“Let me go!” He roared, “This joke is sick, you’re all sick!”

Twilight shook her head, her horn glowing to life as a gag suddenly formed in his mouth, made out of the same purple magic that now wrapped around Twilight’s horn.

“I told you he was going to be like this. He’s such a baby. Now Shining, stop struggling, all you need to do is lie there and let me fuck you senseless, breaking your wedding vows and committing incest, then your blood, which will be filled with the sin of lust is spilled from your body, and you just need to lie there and die so that Cadance can use your soul and your blood to complete her transformation. It’s not hard!”

Of course, this did not help ease Shining’s worries in the slightest, and he begin to struggle even harder against the stone slab, earning yet another sigh from Twilight as shuffled back on the stone slab and pressed one of her hooves tentatively forward until it pressed into the base of his cock, starting to calmly rub up and down while Shining screamed and struggled wildly, desperately trying to get free of the stone slab.

“Stop being such a baby, it’s only being stabbed to death and sacrificed to a sex demon.”

Cadance tittered softly “He’s always been a wuss, he did not even want to try anal in the bedroom!”

Twilight chuckled and begin to rub his cock faster, the poor stallion trying his best not to get aroused. But no matter how hard he tried to fight his urges, his cock slowly begin to fill with his rich lifeblood, swelling to life against his sister’s hoof.

Shining Armour was practically having a heart attack at this point. He had always had feelings for his sister, yet he had always done well at hiding them. Even with the crippling fear of the fact he was about to be stabbed to death, his penis did not care in the slightest, cock twitching to life against the soft hoof of his sister, the warm frog of her hoof was wrapped so lovingly against his cock.

He desperately wanted to not be aroused by this situation, but there was every little he could do to prevent his body from doing so, his member was soon throbbing frantically against their hoof, his back arching against the stone slab he was strapped down to as he let out a cry of pleasure into the gag that had formed within his mouth.

Cadance let out a cruel and almost mocking giggle upon hearing his moans of pleasure “He seems to really like that Twily, he’s such an incest loving slut, isn’t he? I bet he’s spent ages thinking about doing this.”

Twilight did not respond, her hoof frantically rubbing uup and down his length as the purple unicorn gave a large grin beneath her hood, her hoof beginning to rub faster up and down his tentatively throbbing length as he desperately and hopelessly tried to contain his urges.

There was no fighting it however, his natural urges were far too strong for him to ever hope to fight, and he was soon thrusting madly up into the hoof of his sister, desperately trying to breed her like his instincts were telling him, but unable to do so because of the restraints holding him back.

He was still very scared, that much was still as true as ever, but now that fear was slowly being eroded away by the lust that was tearing through him. He was certainly not enjoying the situation however, his arousal flaring higher and higher as tears begin to streak their way down his cheeks.

Shining knew that fighting was hopeless, but still he hated this. He hated the fact that his sister was raping him, he hated the fact that this whole situation seemed to be a terrible nightmare that he was unable to awaken from.

And non of the females in the room seemed to care, Twilight even giving a soft giggle as she leaned down, the scent of her lavender perfume strong against his nostrils as her hoof kept so skilfully molesting his cock, her rubbing getting faster and faster as his eyes fluttered and he rolled his hips against the soft flesh of her frog.

She extended her tongue forward slowly and pressed it to the base of his cheek, gathering up the first of those salty tears, then slowly dragged it upwards, following the damp trail that it had left in its wake all the way up to the base of his eyeball, her foul sticky tongue leaving a trail of saliva in its wake as its rough surface slowly dragged along his cheek.

And despite all of this, his member still throbbed within the grasp of her hoof and let loose its first thick blog of pre, which dribbled all the way down his length and onto the purple mare’s hoof.

His sister was not sensitive to his plight in the slightest, and right before he managed to obtain the climax he had so desperately been building towards, she pulled her hoof back, cutting off the stimulation and leaving his length throbbing madly against the open air as the pain of a failed orgasm tore through him, forcing him to roughly writhe against his bindings as he let out a cry into the gag,

“Oh no Shiny, you don’t get to cum just yet,” She slid the dagger from before out of her sleeve and showed it to him, chuckling darkly “And when you do cum, I’m going to stab this straight into your chest. But don’t worry, there’s no need to be scared, as your life ebbs and fades, you will be helping towards something… Beautiful something beyond either of our comprehensions.”

Shining realized that this was not his sister, not really. There was something dark and almost rapturous about her state of mind, something that he had never seen in his sister before, and something that had certainly not been brought on by anything natural.

Had he been able to, he likely would have appealed to his sister, tried to bring her back to her senses, but he was wearing a gag, so there was nothing that he could do but lie there and sob softly as tears streamed down his cheeks and his sister prepared to plunge the sacrificial dagger deep into his chest.

And Cadance was no help either, her hoof had moved down and was now beginning to rub frantically at her pussy. Shining knew this despite not being able to see it because of the loud noises that were coming from her direction, and if there were any doubts about it, then the exceptionally loud moans that he knew all too well dashed them within moments.

Twilight pressed a hoof down into his chest to keep him pinned against the cold and unforgiving stone, sitting against his legs as she got into a cow-girl position, her soaking wet cunt pressing against his leg telling him just how turned on she was, even if he was not able to see it beneath the pitch black cloak that she was wearing.

He desperately tried to beg, desperately tried to struggle and push his sister from atop him, but she refused to budge, grinning down at him in a needy fashion as she slid her cunt forward and pressed the warm snatch against his balls, a wide, toothy grin clearly etched onto her face.

“You’re going to cum deep inside me big brother, you’re going to pound your thick fertile cum straight into my baby maker, and then I’m going to put my dagger deep inside your heart and you’re going to bleed out while looking into my eyes and knowing that you just knocked me up… How do you like the sound of that?”

Shining really did not seem to like the thought of that, tears once again streaking down his cheeks as he realized just how helpless he was to his urges.

He realized how helpless he was to his lust. In that moment, his mind seemed to snap, shattering apart like so many shards of glass that tore deep into his remaining thoughts and made pain tear through him, loud sobbing tearing into the gag as Twilight kept rubbing her cunt up and down his length, causing it to throb softly, dribbling pre down it as he bucked his hips hard against her, giving into his urges.

At this point he had given up on getting out of this situation. His life was over by this point, no amount of begging or fighting was going to save him, so he may as well give into his urges.

It was almost like some demonic force was affecting him as he begin to frantically buck his hips against her, attempting to sink his length into the mare.

Twilight looked down into his eyes, seeming to stare straight into his eyes and deep into his soul, realizing just how bad he wanted to plough his thick cock straight into her snatch.

And she was not going to make it easy for him, pulling her hips back and letting out a soft, mocking laugh as she watched him frantically attempt to sink his member into her snatch.

“I think I broke him Cadance… Just a few seconds ago he was a sobbing wreck, and now look at him! He’s so desperate to fuck me.”

Cadance let out a soft cry of pleasure, currently busy ploughing her hoof desperately into her snatch as she looked over to watch Twilight frantically teasing her former husband, ready to brutally murder him under her orders!

It was so hot, and once she did finally turn back into a demon, she was going to kill so many people, but for now she was simply excited to watch the life of her husband drain from out of him.

Shining Armour was also now looking forward to having the life drain out of him, his little sister finally moving her snatch so that it was in ploughing distance for her brother, the dripping entrance to her cunt kissing against the head of his member as he let out a soft raspy moan, looking up into her eyes before needily bucking hips forward like some kind of needy animal.

The large head of his cock, driven by the powerful muscles of the stallion that controlled them had no trouble at all in spreading her snatch wide, slipping inside of her as he let out a needy cry, forcing his hips forward with all the might that came from a lifetime of being a guard.

Naturally he had no trouble at all in sinking the whole of his length into her thirsty cunt, letting out a sharp cry of pleasure as he arched his back hard.

SMACK. The sound filled the temple around them, seeming to echo off the walls as his hips met those of his sister, impacting against each other with a brutal amount of force that made Twilight scream in pleasure, her eyes rolling back in her head slightly as she felt the large length of her brother enter her.

The impact, followed by the wave of pleasure that filled her was almost enough to make her drop the dagger she had been so desperately wanting to stab straight into his heart, leaving him for dead on the stone slab and letting his blood spill free to fuel the transformation of his wife.

She did not let it happen however, her fingers curling tightly around the blade as she forced her eyes to focus, rolling them back into place and then panning them down to look into the needy eyes of her brother.

Twilight did not even need to do any of the work by this point, Shining Armour let out a needy moan into the gag that was jammed into his maw, then begin to desperately pump his hips back and forth, roughly slamming his length in and out of her velvety cunt, which roughly convulsed around the length, trying to pull it deeper into her even though her brother had already given her everything he had.

His breathing was heavy, and by this point Twilight was not even doing any of the work, Shining Armour was doing it all on his own, roughly beginning to slam his length in and out of her like he was trying his very best to pump a foal into his sister’s baby factory.

He screamed in pleasure, his fingers curling against the cold stone of the sacrificial slab that he was chained down to, trying his best to keep pounding his incest stick in and out of his sister’s hole, all wedding vows and sense of deficiency forgotten in the face of overwhelming pleasure.

Nothing else mattered to him, nothing else besides giving everything he had to pounding a load deep within the depths of his sister. Already his cock was throbbing, dribbling thick ropes of pre already, his face screwing up and looking ready to burst as made animalistic noises.

Twilight would have normally poked fun at this, she would have mentioned just how easy it had been to break her brother, how he was now nothing more then an animal. Unfortunately it was currently impossible for her to do so as she had his cock roughly slamming in and out of her cunt with a brutal amount of force, his powerful hips smacking straight into her clit as she let out loud squeals of pleasure, feeling like at any moment her own heart was going to burst.

She had seen how big her brother was before he had sank his length into her, and sure he was big, but now he was inside of her, he felt even bigger. His powerful muscles were driving his hips back and forth with a mind numbing amount of force that was doing just that, her mind so scattered that it was impossible for her to even come close to thinking straight as her fingers curled even tighter around the handle of the dagger.

Where was she? Who was she? All of these were questions that tried to make their way into her skull before being wiped away by the waves of pleasure, like sand castle before a tidal wave they were all wiped away, leaving only the blank sand behind.

She could tell that she was approaching a climax, she could feel it building within her, and she could feel her brother was also getting close as his length was starting to throb softly inside of her, bubbling pre like a fountain as his eyes begin to flutter, getting closer and closer to blasting his load within his sister.

The purple pony reached a hoof down and begin to rub at the area above her cunt. She could feel his cock through her flesh, pounding away her willpower and forcing her closer and closer to an orgasm, screams of pleasure tearing from her lips as she felt the orgasm getting closer and closer.

Twilight was sure that she should have orgasmed already, her eyes rolling back in her head once more as her free hoof reached down and begin to needily rub at her clit. She wanted her brother to blow his load deep inside of her, to blast it deep within her womb.

Images of her getting knocked up, filled with his incestuous foals flooded her mind and sent her even closer to an orgasm. Her hoof reached down and pressed against her clit, starting to frantically rub it in a desperate attempted to send her over the edge.

She should have already orgasmed, but for some reason it was just out of her reach. Shining Armour let out a loud cry of pleasure, his cock throbbing rapidly within her cunt, giving a roar of pleasure before he bucked his hips forward hard, hilting deep within her as his cock begin to throb rapidly.

Twilight then felt thick ropes of cum deep within her snatch. She felt the warm cum coat her inner walls, which begin to convulse hard around his cock in a desperate attempt to milk him.

The moment she felt the first rope splatter into her cunt, she let out a loud howl of pleasure and swung the dagger down, stabbing deep into his chest as she screamed in pleasure.

The dagger sank deep into his chest, his eyes flying wide as he stared up into her eyes, mouth hanging open as shock filled his eyes, his whole body starting to convulse beneath her as his cock kept spraying his seed inside of her, before he let out a soft rasp, eyes rolling back in his head as he begin to die beneath her.

Twilight had never felt such pleasure in her life, screaming out as her whole mind seemed to shatter from the pleasure that was tearing through her mind. The purple mare felt multiple orgasms tearing through her. Blood splattered onto her chest and she begin to brutally stab her brother several more times.

He tried to scream into his gag as his hips kept bucking his hips back and forth roughly, gagging and crying out as blood begin to spill and bubble from out of his chest.

Twilight fell backwards off the stone slab, gasping softly as her brother’s length ripped from within her walls, leaving her with a terrible empty feeling as she fell gently to the ground.

Shining Armour was not in a good state at all, the purple pony was still splattered with warm life blood, and Shining Armour was still producing more of it, letting out a panicked scream into his gag as he thrashed about against the cold stone.

Blood was bubbling out of his chest in an unnatural fashion, flowing down the sides of the large stone slab, flowing from out of his chest and then down onto the gutter that led to the tub Cadance was currently busy rubbing herself within.

Once it reached her, all hell was going to break loose.
