Two Hearts Becoming One

With post-nut clarity taking hold of Twilight she took a moment to rest in her chair, her mind processing the full extent of the changes to her form. The fact that the Sisters were now her cock and balls, and that her coat had changed a bit to reflect Celestia’s merging with her. Within her, she could feel warmth, a mix of arousal and that warmth from thinking about a lover. Deeper though the flame of desire burned within her, a low-level lust and craving for pleasure, something she was certain Cadance always had felt.

Beyond that, she had a craving to do what she had done, or more of what Luna had done to herself with the help of Twilight’s new anatomy. Part of her hungered to consume her citizens and then splatter them as cum against a wall or in some willing vessel. For now, though, her thoughts were clear enough to coherently think.

As she went to address Cadance she saw her sending a letter away with a very brightly blushing guard.

Before Twilight could ask, Cadance spoke. “I’ve already sent for Rarity, and that guard watched the whole thing, poor stallion reeks of arousal.”

Twilight just sat there with a finger up as she processed what Cadance said.

“Anyways, are your thoughts clearer?”

“Yes, I… This will take some getting used to.” Twilight replied. “Wait, why are you sending for Rarity?”

“Well, she's your friend and she lusts for you,” Cadance answered, Twilight knew Rarity had the hots for her on and off over the years. “Two, your wardrobe needs updating.”

“On point two, I can magic clothing for myself.” Twilight frowned.

“As in Illusions or actual conjuring clothing?”

“Yes.”

“Ah, well regardless wouldn’t you enjoy having her do some fitting for you?” Cadance teased.

“Yes, but that will likely devolve into railing Rarity.”

“Which is a good thing.”

“Stop thinking about my sexual needs, I’m a Princess.”

“Queen, actually.”

Twilight sighed, she had been referred to as Queen Twilight for some time now after taking the throne. On reflection of the fact, that she had absorbed only two other ponies with a valid claim to the throne the title of Queen really wasn’t wrong anymore. Nor would Empress, not that Equestria was formally an Empire.

“And what, you’re now Queen Cadance?”

“Queen or Empress, I mean I do rule an Empire.”

“Fair enough. Well while we wait for Rarity to get here maybe you can tell me more about what happened in your Empire?”

“Oh, certainly, which part do you want to know about?” Cadance answered, seemingly unphased by the casual nudity going on, and if Twi didn’t know better, the absentminded masturbation of vestige of her brother.

“Well, how my brother became physically one with you.”

“Oh my, going right for the most erotic of the stories I have to offer. I guess somepony has caught the chronic horny.”

Twilight sputtered and blushed. “What, no, well yes, but that’s not why. I want to know why my brother decided to join you as Celestia and Luna did.”

“Very well, I mean, he always wanted to be as close to me as he could, forever. And now? We are, but I’ll tell you how this came to pass.” Cadance giggled. “Also don’t forget to hydrate, absorbing and transformations take a lot of energy, and you sweated a lot.”

Twilight was now flustered with how casual Cadance was taking this, but summoned a pitcher of water and started rehydrating as her fellow queen started to tell her tale.

Two weeks ago in the Crystal Empire.

“Shining, my love, you seem distracted, what weighs on your mind?” Cadance asked her Prince Consort.

He stood there looking out on the Empire he swore to protect, the Empire his wife ruled. He couldn’t see it directly, the magic corrupting the will of all those who lived here. That reduced their inhibitions and drove them to copulate in more and more debaucherous ways. But he could feel it, between his horn and his loins he could feel that magic as it affected the Empire and himself. A day ago, he was torn between throwing in the towel and joining his subjects in debauchery and fighting this magic. Today he was throwing in the towel, it was far beyond his skill and nobody was really getting hurt. No laws being broken, no issues of consent.

It was more just that everyone was extra horny but still had their sensibilities not just to do it in the street in front of foals. So there was no harm in giving in, though that too was what the magic did to those afflicted by it, made them give in to it and their desires. But again, no harm had come from it, the Empire still was running as smoothly as ever despite the addition of more breaks for those working, because nobody could keep focused for too long anymore. So-called ‘nut breaks’ were now a legal requirement, and break rooms expanded to include a space for workers to evacuate their desires and get back to work.

Part of that boggled his mind given how debased some of what happened were, between ponies merging and becoming one, others being reduced to cum only to reform minutes, hours, or days later. Mares and stallions had foals as they desired and that was keeping on track with safe population growth. Then again for purposes of population, those who merged were only a single person, usually, in terms of resources required.

On paper, it should have been an absolute nightmare to resolve and square all this up for number keeping and law, and yet, somehow, it had taken only a couple of days once what was happening was understood. As if the magic infecting everyone willed them to a predetermined solution so everyone could get back to having fun.

That was the part that burned him, as his wife pressed her soft plump chest into his back, her soft stomach present into him all in an effort to comfort him as he looked out on the city. He should be having fun, he and Cadance always were fairly active yet this whole thing had decreased how much they had been enjoying one another, though it had made them try new things out.

“I am squaring some of my issues with everything going on,” Shining replied after a few minutes of introspection and Cadance gently stroked him from behind.

“And how are you going to do that?” Cadance cooed before nuzzling his neck.

Shining’s face was burning with blush as his groin burned with arousal. “Well, I want to… try something more with you.”

“Oh? I thought you wanted to do everything to resist the magic.”

“I… can’t resist it forever, and it seems to have, if anything, made life better. So why keep fighting it? Doing so has just made me frustrated.”

She held him tightly, those large muscles of hers flexing around him as she waited for him to go on.

“I think I want to do what a number of couples have done.”

“Have another foal?” Cadance teased.

Shining shook his head with a chuckle. “No, well yes, I wouldn’t mind seeing you gravid again, it did fill me with a kind of pride.”

“It filled me with something else.”

Shining chuckled at that. “True, but what I want is something else, but it’s hard to put my finger on it.”

“Oh? Well, maybe you can describe what you’re feeling.”

He nodded before turning in Cadance’s arms holding her as she had been holding him. “I love you, I fucking adore you. I can’t stop thinking about you and lovely it is to be pressed against you like this.”

“And?”

“And sometimes I want to know how you feel, not just touch but the sensations you feel.”

Cadance giggled again. “So you want to become my Gleaming Shield instead of my Knight in Shining Armor?” She teased him.

Shining for his part rolled his eyes, the idea of swapping sexes for good was appealing, really appealing actually, something of that notion resonated with him. “Yes but that isn’t it, though maybe it’s more about being your shield instead of your knight.”

“Mmm, a few ideas come to mind about that notion.”

Those ideas he could ponder himself, there were a couple of ponies who were nothing but objects now, though with a bit of magic one could still connect to their mind and chat with them.

Shining kissed Cadance before speaking again. “Well, same, but being yours, absolutely yours, is part of it.”

“More than you are now? It is hard to imagine what that might be.”

That was what Shining was having issues with as well. “I know, but no, I want to… be with you, in a way only this magic will allow.”

“Oh?~”

Something about her answer made Shining realize how much more predatory she had become towards him, how she was touching him, pressing against him, claiming her ownership of him. Though that ownership was going to change, not in that he was going to dominate her, but that he… It was still hard for him to put into words let alone think about it.

“I want to be part of you.”

“Which part, dear?~” She cooed, daring him to answer.

He stammered and questioned himself, what of her did he want to be? Just become with her and feel what she felt, share in her pleasure as they, as one, were pleasured by whoever desired them? Or was it something more focused? The answer dangled just beyond his senses as her touch moved to pleasure him.

“Maybe we should experiment with what parts of mine you enjoy the sensation of.” She cooed into his ear, her fingers moving to his member as her horn touched his and he could feel what she felt.

His groaning stopped as he only felt her side of things, though there was an almost unbearable lust within her heart he now felt. A mighty need to be filled. He let Cadance control him, riding her sensations as she rode him, feeling his own touch on her skin, feeling his exploration of her body as she pleasured him, filling his mind with options of what to be. Deep within himself, he was split between being with her or being like her, the connection was intoxicating making judgment hard on what he wanted. But he knew he wanted this pleasure he felt through her as his own.

The temptation to swap bodies was strong, the temptation to have Cadance swap one of her sexes with him and make him as sensitive as her, more elastic, and just as horny was powerful. Part of him longed to just be fucked stupid endlessly, day after day. To be nothing more than a tool of pleasure.

That last part stuck with him though, he could feel everything Cadance felt if he was one with her. And as such he would be with her forever, fulfilling a deep desire he had to not leave her alone in her alicorn life. But also being a tool of pleasure resounded deeply with him, what better than to become one with his wife as a part of her meant, for one thing, pleasure. Given the times he had let her swap their sexes to feel her side of things he knew she would enjoy having a cock, so what better thing to do than to give up his flesh to become her cock, her rod of pleasure, while sharing every sensation she felt from now on? The thought was, again, intoxicating. And it was something only this strange lewd magic could allow.

“I want to become your cock.” He answered, feeling the embarrassment, and then let out a yelp as she kissed his neck and squeezed him with her strong arms, reminding him of her nature as not only the lovely mother of their foal but also just as built as he was. Plush and Pumped were a very lovely combination after all.

“Well~ Now I believe that can be arranged. Though I already have one, I guess you can add to it~” She purred into his ear. “But not here, I think something like this deserves some ceremony. It isn’t every day the Prince Consort becomes truly one with his Queen~”

He had to agree with that, and his body was excited at the prospect, he had seen a few stallions do what he desired to do, to become their mare’s cock. To be part of them for good, and not just any part, but part of that brought her deep pleasure and joy. Forever would he be there to pleasure her.

“Now then, I feel the Heart chamber will be a good place for this~ It should only be a few hours, until then, let me help you relax because soon we’re going to have issues doing it like this, because soon it will just be a quick wank session for us”

Those words stuck in Shining’s head, that she had long ago considered this to be his eventual fate. There would be no way back, and that prospect excited him deeply and made him feel a pleasure beyond any orgasm before.

The Next Day

It had taken more than a few hours and there was something about the idea of doing it at dusk that was exciting and felt correct to them. As such plans were put in motion and the decorations set up. Though to call them decorations was pushing the term, most of it was stands for those watching and stockades for those desiring to be used during the ceremony. Of those who ‘sacrificed’ themselves for the crowd were Celestia and Luna, who had in the past two days given in to the magic and allowed for the citizens of the Empire to use them endlessly. If Cadance had to guess the more magically inclined someone was the more susceptible they were to this wonderful lewd magic. Given both of the Sister's bodies had changed a little, namely the size of their sacks and cocks they had ‘snacked’ on a few ponies. This wasn’t a surprise when it came to Celestia, she always liked overdoing it with her food, as evident by that bit of motherly pudge she always had.

But the sight of the two having fed their cocks some willing ponies gave her an idea of what to do to fill the time getting used to the soon-to-happen changes. And an idea of what to do once this second honeymoon was over. Twilight would be easy prey, and oh how cute the noises she always made when Cadance spent some alone time with her. And what better way to turn her to loving this magic than by making her indulge in it? Regardless of future plans, the curtains were drawn around the Heart Chamber, with the sunset colors refracting through the crystal structure illuminating the chamber in warm hues of dusk.

Pleasured moans filled the air as Cadance stood there in her full glory, basking in the attention of her people at her figure, her form. She knew no small part of the audience was pleasuring themselves to the thought of being with her right now. Between her impressive alicorn cock, her motherly body, and her status she knew there was something for everyone here to enjoy with her body. Plus there was a small part of her that wanted them to come down and just as a group fuck her until the end of the week. But that was not something to start with. No, Shining’s desire came first.

For his part, Shining was used to being naked, for what reason Cadance was uncertain. But he didn’t hide or shrink away from the eyes of their subjects. His stallionhood was on full display, partially erect knowing soon what was to take place, and his member was nothing to sneer at. A great cock on a wonderful stallion. She could taste his desire for what they were about to do, and that just whetted her appetite even more.

As the chamber lit up with hues of passion from the diffraction of sunlight, with a little bit of coercing from Celestia for this fine moment, the time was right. Words slipped from Cadence’s lips while her mind focused on letting the lewd magic that permeated her Empire fill her. The words were only put to voice the desires of those around her and as such only were to whet the desires around her, amplifying the magic of love and lust.

Shining felt himself grow erect, his need building as his wife announced what was to happen. For them to couple one last time, in front of their empire, and become one. To fill the Crystal Heart with true love and the depths of its magical power. To fulfill their purpose as its rulers and spread love to the rest of the world in time. He knew that the magic would take time to flow out of the Empire into the rest of the world. But he knew this was the right thing to do, for him and the world. This love would bring change, change that he saw what it would do and found comfort in.

The Heart as if sensing their intent lifted higher than usual, the palace itself bending to it to make space for them below it. As the two held one another they paused in reflection, the gentle hum of the Heart above them. Their excitement rubbed between them as they embraced.

“Are you ready, my love?” Cadance asked him, knowing the answer.

“I am, let us, as our vows said so long ago, become one,” Shining replied, to which Cadance smiled softly as his words made her heart warm and flutter a little.

“Good thing you can still say such sweet things to me once we are one. Otherwise, I would deeply miss your way with words.”

To that Shining blushed before kissing his wife. In return, Cadance summoned a bed of crystal from the dais below them for the deed to be done. As they embraced and sank to the table she connected her horn to his and let her senses start to bleed into him, and his into hers.

For Shining there was no turning back as he began to take his wife one last time before he was one with her. Feeling every inch of her body as she did the same to him, their lust overflowing into one another through their bridged feelings. His mind felt at home with this shared experience as he penetrated her, feeling himself being penetrated as if they had swapped places. Slow but firmly he began to let his passion fuel their pleasure.

Their lips parted and their moans of pleasure and lust filled the air, joined by a choir around them. Shining could feel himself lost in the shared sensations, uncertain at points if Cadance was controlling his body or not. It didn’t matter, it felt too good to stop, and he didn’t care if she did, they were one, if not in body then in soul and mind. Part of him let go of the desire to control himself, letting the firm passionate mating change to more lustful rutting as he lost himself in feeling both sides of the sensation of fucking and being fucked. The overflow of sensations washed away his sense of self.

There was no more Shining and Cadance, there was only Cadance, of two bodies pleasuring herself for her Empire to watch. And watch they did, filled with lust and using one another to feel some of the pleasure they saw unfolding in front of them. The birth of their Queen.

As Cadance rode Shining, bouncing on his lap, her cock slapping his chest with a meaty thud over and over, playing out across the enhanced acoustics of the Heart Chamber, mixing with their pleasured moans and needy desire and in return a chorus of pleasured moans and gasps from their audience. Lust and love burned equally around them, and the magic that had taken hold of the Empire grew empowered almost as if by ritual with every minute that passed.

Shining noticed it while Cadance was enraptured in pleasure, her cock was having a harder and harder time peeling back off of his chest as it leaked precum onto him. His thoughts fluttered and fizzled between the twinned pleasure of himself and his wife. The sensations were confusing and overwhelming driving him into the white bliss of a full-body orgasm. As he came again he felt her cock thump on his chest but fail to come off even as she kept riding his cock. Then he felt the change start.

It was like a faint tingle at first, running from chest to groin, feeling her cock and balls bonding with his own body. Maybe she realized this, moving to grind on his pelvis, swirling his cockhead within her passage. As Shining came for the first time he curled his hooves his thigh and calves tensing up and then failing to separate. His hands moved from his wife’s thighs to her cock, rubbing it before sticking to it. He could see them starting to become one with her, and it excited him, he gasped for air before pressing his muzzle against her cockhead, kissing it, lapping up her pre, wanting to taste her one last time.

Cadance after her second orgasm was watching, greedily drinking in the shared pleasure as she grind on Shining’s cock, enjoying feeling him so deep in her and filling her in front of their subjects. She watched as his features began to melt but it didn’t stop him from pleasuring her, slowly though her cock started to sink into him, she altered the bed they were on, letting his legs dangle off the new edge of it. She looked behind herself lifting her tail and watching as his legs curled in pleasure and began to melt together.

She moved her hands to rub Shining, groaning in pleasure as she felt as if she was jerking herself off. Feeling his chest having softened bone joining muscle in becoming her massive cock. A squeal of pleasure escaped her lis as she felt his climax again and again as more of what he was to become one massive sexual organ. Her sexual organ. Grinning between gasps and thunderous Canterlot voice-empowered moans she continued to pleasure herself and him.

Shining’s face started to smoothen, his jawline becoming the new edge of her massive marecock, she could feel the intense weight of her new balls that once were his powerful legs. Now they were powerful reproductive tools and muscles to push that life-making concoction forth.

For Shining he felt more than saw, knowing he couldn’t even mouth the words he wished to say he tried anyways. From his lips he could feel the flow of her cum, it tasted heavenly to him, a taste of the pleasure he got to enjoy forever and that prospect excited him beyond imagination. His entire being throbbed with need, his thoughts singular, and his desire burned. He needed to cum, he needed to spill the contents of what was now his guts, which were her sack. A shiver ran through him as he felt Cadance pleasuring his body, no, her cock.

Shining attempted to mouth something but only pre came from what remained of his lips, she knew he was close, to his last separate orgasm, and close to becoming one with her forever. The thought of it made her chest warm and fuzzy. She deeply desired to keep him close forever, and now she could, and she could share with him every pleasure she felt. Every dirty thought and wet dream. It was more than she could have ever hoped for.

She hugged her new improved cock, kissing the head as she rubbed it with her tits and arms before feeling three orgasms at once. As if sensing the importance of this moment and responding to the three orgasms she just felt her sack feel incredibly heavy. The need to cum, to ejaculate grew as the orgasms rolled through her. Such pleasure made her vision turn white as her mind became drunk with pleasure.

From her cock she released a fountain of cum, easily hitting the crystal heart only a short height above her horn, showering herself with a prodigious amount of virile cum. Her marehood squeezed what last remained of shining, milking his final climax into her, she was uncertain if he’d conceived another child with her in his last moments as a separate person.

But now she felt complete, as did Shining as they stood there as one perfect union. Whatever desire they had down the line they knew they could make happen with this intoxicating love magic that had been bestowed upon them and their empire.

The crowd at this point was beyond saving having given into the rapturous throws of pleasure, drunk on the magic spilling out from Cadance filling them and in turn the Heart, the sky itself reflecting this with the strange warm hues of love magic overloaded with lust. Celestia and Luna were no better off than the rest, given the size of their sacks and stomachs they were perfect examples of what this magic could do.

Smiling she looked down at her magnificent body and the changes her husband had made to her, seeing his cutiemark sitting above and to the left of her massive cock, a forever reminder he was part of her, and exactly what part forever emblazoned on her body. Something she’d make certain to keep visible from now on, what he did for her was worthy of forever being known by everyone who saw her.

Present

“And that’s how I spent probably about a week in a constant orgy with myself in front of a crowd of crystal ponies and the Sisters.” Cadance finished as if it was nothing at all.

Twilight was having a hard time keeping her arousal at the story from showing. Though Celestia was betraying her by standing erect as Twilight’s cock.

“Are you alright, Twilight?” Cadance purred, already knowing the answer.

For her part Twilight was having memories of the Sisters of the week of debauchery up north fill her head causing far more than the usual amount of blood to rush from her head to her loins at every recalled sensation. She even let out a cute moan as she was made to relive the pleasures of others.

“Ah, that would be a yes. Well, hopefully, Rarity shows up soon, as much as I’d love to ride you again I think you need someone more long-term to take care of your needs.” Cadance teased the overwhelmed Twilight.

And then Cadance heard a squeak of embarrassed arousal that came from a just arriving Rarity. “Oh dear, what is going on in here?” Rarity asked, her refined voice maintaining while her demeanor was slipping.

“Well, it looks like it is time for you to do your duty as Twilight’s subject.” Cadance purred, licking her lips in anticipation of the show that was to come.
