Late Night Illusions into Bright Morning Hues

Summary:

The forced mermaid au that absolutely no one asked for.

"Half-human, half-fish. Mermaid, the humans called it, he was a mermaid now, or rather, a merman. And not in the sexy, cartoonish ways often portrayed by various types of media he had consumed, oh no. What those films and happy little drawings had failed to mention was how, after his transformation, his human skin had begun changing and mutating, losing its normal colouring in favour of a deep grey, and seemed to have a resistance to being sliced, his blood vessels deeper in the skin than before."

Notes:

Sup fucks, it's me, Raccoon Dante, again, back with another fic, and this time, I don't come alone!
queenofoldvalyria1 gave me a large portion of the ending ideas, and so, I've added them as a co-creator!
Go read their fantastic works!

And as for the gifting, I'm gifting it to you all for the exact same reason. You fueled my egg obsession. So this is both as a thanks and a proof of just how much the idea tormented me. I love you guys, thank you so much.

Special thanks also go to the DanVer Daze server for putting up with me in my egg obsession. You guys all rock and without you, I'd be nothing.

Work Text:

He hadn't expected this at all, just like how he hadn't expected Vergil to win, Dante thought to himself, wincing as Vergil's hips continued to slam into him from behind, the evidence of their previous rounds dripping down his body, just like he hadn't expected Vergil to claim him and then force his demonic form to change.

But of course, Vergil had, somehow, done the impossible, the lucky fucking bastard, and had managed to defeat Mundus, with Dante's help, of course, becoming emperor himself, and claiming Dante as his queen and consort, willingly or not. And Dante most definitely was not willing.

He'd never quite got a straight answer to how Vergil had done this to him, despite how many times he had tried to ask while the transformation was incomplete, when it still terrified him that he had lost use of his legs. Vergil had just smirked and told him he was becoming the queen the demons needed. Not that Vergil was ever that forthcoming anyway.

Nowadays, He mostly just used it as a chance to debauch Dante as much as he could, using the feeding of semen as a chance to use Dante's jaw and mouth, using it as both a way to humiliate Dante further in the court and front of the demons that came to grovel at his brother's feet, a way to claim him in a way all could see and a means of using his own pleasures for Dante's feeding times.

Three times a day, Vergil would order one of the lesser demons that served him, and had enough intelligence to understand commands, to have him moved from his main tank, to his “feeding tank” tank at the base of Vergil’s throne, killing any who dared to spill even a single drop of the precious water inside the feeding tank that kept Dante alive, or even daring to think about harming his precious Dante.

He'd then give some speech about how the demonic realm was stronger now than it had ever been under his leadership and now had a queen to produce a strong line with, blah blah, yadda yadda yadda. Dante had heard it too many times to even care about listening.

He knew Vergil deeply hated him ignoring it, but Vergil had also learned that Dante did whatever the fuck he wanted to, whenever the fuck he wanted to. It was a give and take situation between the two of them. Vergil would give Dante a yard, and Dante would take a mile in return, and nothing Vergil could do would stop it.

No amount of asking or telling him would change it, nor however many fights they had had between them before Vergil changed him, which had most likely been part of what had made Vergil change him and after he had changed, Vergil had quickly learned, and so, the court had come to understand that they both shared the power of the throne, even if it’s queen was only a figurehead.

The demons who came to see his brother still had to bow to him, still had to swear fealty to him, which made some part of him preen that he was being acknowledged as queen, even if he couldn’t give orders out as Vergil could. Dante still held a large portion of the power behind the throne, because Vergil would do anything to keep him happy, or as happy as he could, because Dante, most definitely, most assuredly, was not happy.

Even if Dante knew he didn't hold any of the power that Vergil did, As long as it kept the court happy, believing that even in this form, he was just as powerful as Vergil, and as long as Vergil was with him, he was something close to happy, even if he wasn’t quite there.

Vergil meant the world to him. Dante would endure anything to stay with him, to keep Vergil bound to his side and prevent him from ever having to lose him again, even if that had eventually turned to Vergil forcing a mating bond onto him, and then tricking him into becoming...Whatever he was now. Some kind of fish-human-demon hybrid.

Dante still had the healing capabilities afforded to him by their inhumane pedigree, allowing him to recover from whatever damage was caused to him, even if the smell of his own blood made his new, baser instincts screech at him for daring to allow himself to become vulnerable enough to actually bleed.

Half human, half fish. Mermaid, the humans called it, he was a mermaid now, or rather, a merman. And not in the sexy, cartoonish ways often portrayed by various types of media he had consumed, oh no. What those films and happy little drawings had failed to mention was how, after his transformation, his human skin had begun changing and mutating, losing its normal colouring in favour of a deep grey, and seemed to have a resistance to being sliced, his blood vessels deeper in the skin than before.

He supposed that it would have aided him, if he lived in the ocean. The thicker skin would have made him able to survive at deeper depths than a human, and the blood vessels would have prevented him from being detected by those who smelled, while the colour would have perhaps aided him in blending with the seafloor and escaping predators. Here in the underworld, however, there was only one predator, and his involuntary camouflage and thicker skin did nothing to help hide him from Vergil.

Once Vergil had finished his monologue to the gathered hoards of demons, he'd then turn his attention to Dante, carefully coaxing him out of his hiding place, Vergil would offer him a small smile that he reserved only for him, which would make Dante think that perhaps things really had begun to change.

His twin would dip an elegant hand into the water, as though offering to hold Dante's hand.

Dante knew this show, knew the game too, and still, he played right into Vergil's hands each time.

Vergil would then take the opportunity to grope at Dante's changed body, hands slowly and gently tracing the scales of Dante's tail, carefully brushing over his dorsal fin, making Dante gasp and shudder, smirking all the while, before slowly ghosting his fingers over the darker flap of skin that covered and protected Dante's cloaca, delving his fingertips in only enough to make Dante squirm before pulling them out and cleaning them with his own mouth.

Throughout all of this, Vergil would be stroking his own clothed cock, bringing himself to hardness, before grabbing Dante's neck, covering his gills with his hands and forcing Dante to the surface, gulping down mouthfuls of air and then shoving his hard cock into Dante's mouth with a soft moan.

It was both a chance to feed Dante, binding his twin to his side with the addictiveness of his cum, thanks to the transformation and to also take the chance to fuck his throat at the same time.

Once Vergil had come deep in his throat, filling his stomach with cum, the only food he could handle since his transformation, Vergil would then go back to groping him, using his hands to explore Dante's torso and pressing his fingers into his greyed skin, enjoying the give of it, and listening to Dante’s noises.

Not that Dante had much room to complain. His tank was spacious enough, being fitted in a wide hovel behind the throne, replacing the tacky decor Mundus had once displayed, and contained lovely florets of coral and seagrass decorating it. His tank was essentially its own ecosystem, made just for him, to keep him happy.

Vergil had spared no expense in making him comfortable in his new body and new home, going so far as to fill his tank with tropical fish and even a sea turtle that had its own rock that stood above the water so it could rest and bask in comfort too, to keep him company. Vergil had even been gracious enough to provide him with a tiny saltwater, solar-powered radio that he could listen to music on.

Even though Vergil hated the music he listened to, he never once complained about it coming from the radio, no matter how much he watched Dante laze and swim around on the days the court was less crowded and fewer demons clamoured for his brother's attention, or how loud Dante turned it up, blasting it while he relaxed in the warm water surrounding him.

But it wasn't as if Dante could complain anymore, or even had a voice that worked above the water, thanks to what Vergil had done to him. In addition to all the things the transformation had given him, it had also removed his ability to use his vocal cords above the water, allowing him only the ability to screech and whine like an animal with baser instincts.

Under the water, it was mostly no use to talk. Vergil never listened to him, instead insisting that he spoke a language he didn't yet understand.

It was probably bullshit, knowing Vergil.

But then, had Vergi ever been that good at lying to him? Perhaps things had changed, or perhaps not. Without other humans around to collaborate Vergil's story, Dante would never know.

Still, there were small signs that Vergil did care for him beyond a physical sense. The way he would sigh when watching Dante swim, the way he would stare at Dante's tank with a forlorn look on his face, and occasionally...

Occasionally, on the days when Vergil's temper reached a fever pitch, when the cacophony of voices that vied for his attention became overwhelming to such an extent that watching Dante did nothing to help and even Dante found himself flinched away from the sounds of the uproar coming through the glass in his tank, and he began cowering under a small outcropping of rocks in his tank...

Then and only then, would Vergil order Dante moved into a smaller tank, the demons dragging him by his arms and tail, no matter how hard he tried to protest or fight back, and have him moved to Vergil's own chambers, and follow swiftly alongside as the demons ported Dante, sometimes dipping his hands into the tank to pet Dante's hair, ignoring the attempts Dante made to bite at his fingers as he did so.

Once they were alone in Vergil's royal chambers and the helper demons had left them both to their own devices, Vergil would sigh softly, and speak to Dante in low, mellow tones, apologising for the state of the court and for being unable to prevent Dante being bothered by it, before allowing a lazy arm and hand to delve into the water, calmly coaxing Dante out from the rocks.

It was these days that Vergil allowed Dante to truly feel like his queen and consort. It was one of the few times Vergil was gentle with him and allowed him to feel pleasure too, as much as Dante hated it.

And while Dante was eager for the tenderness those days brought to them both, Dante hated everything Vergil would do to him. But it was his own fault for allowing Vergil to put the bond onto them, incomplete as it was.

He'd gently coax Dante to the surface and pull him into a tender kiss, exploring Dante's mouth and feeling his twin's body shudder against him, as Vergil's hands wandered his body with a reverence that even left Dante breathless.

Vergil would pay special attention to the dorsal fin on Dante's body, the one that stretched from his shoulders to his coccyx, knowing it was sensitive and more often than not, arousing for Dante. Even Dante couldn't control his bodily reactions.

Vergil would then continue to follow the length of Dante's human spine, before coming to rest at a darker patch of scale and press his fingers into it, stretching and preparing Dante for what would come next.

Once Dante's slit had opened fully, releasing his slick, and his body shivering from both the cooling air and the lust burning through him, then, when his very blood was urging his body to mate when his brain was fighting against every moment.

Then, Vergil would gently lay him out on his bed, tearing himself away from that lovely mouth to bite and suck Dante's skin and scales, meandering his way down Dante’s body, feeling the delightful shudders and the way Dante arched into his touch, the fire that lit his eyes, the lingering embers leftover from his demon, the leftover of a time long behind them.

Oh, Vergil knew fully well that Dante had no wish for this relationship, but thanks to both the transformation and several other components that had been tied to his own body. Dante was unable to stop him, unwilling to fight back, even though his mouth was full of tiny knife-like fangs, designed for tearing through flesh and bone, designed to seek out that gland at the base of Vergil’s neck and bind them together. If Dante ever gave himself fully to Vergil anyway.

On the rarest of the rare occasions, Vergil would proceed to eat out his cloaca, leaving Dante a whining, shivering mess of himself before carefully fucking him into the bed.

It was never making love to him, no matter how many times Vergil tried to tell him that it was. There was very little love from Dante's side of his quote on quote relationship.

"We're going to try something different this time, beloved." Vergil spoke quietly, fingers tracing Dante's skin and scales. Dante shivered, and Vergil just hummed softly, dipping his fingers into Dante's cloaca, listening to his sweet twin whine.

If Dante had still had a working voice, he probably would have been pleading with Vergil to leave him alone. He was already overwhelmed from the noises of the court, and from the previous days of Vergil pounding him into the silken sheets of his bed.

The week had been a particularly bad one. The entire demonic world was in an uproar about some shit that went over Dante's head, and he could tell that even Vergil was becoming annoyed by it.

But still, his stomach was empty of the semen his brother forced down his throat, he was hungry, and his stomach had been swelling in the last few days, for reasons he couldn't quite understand.

The hunger made him whine in response to Vergil.

Vergil, if he was honest with himself, did miss Dante's voice, annoying as it was. He deeply missed the moments that the brat's resistance would turn from stopping him to slowly encouraging him to keep going and the sounds and words of pleasure his sweet twin would give off in waves as Vergil's seeking fingers delved deeper into his body, torturing his prostate was heavenly.

The silence, however, was much easier on his sanity, and it meant that he no longer had to listen to Dante begging him to stop - stop what exactly, he hadn't found out.

But even without a voice, Dante still tried to fight back, squirming and thrashing in Vergil's grip, but he was so much weaker than Vergil now, his attacks with his claw-line nails didn't even scratch Vergil, and the tail thrashing was more of a nuisance than a cause for concern.

But he still tried to fight back, and that's when Vergil's "Unlimited Patience" Capital U, Capital P, would snap, and Vergil would summon one of his spectral swords and slam it through Dante's lower spine, severing it clean through, and stopping Dante's lower body from being able to fight back.

It also made the pain of Vergi entering him non-existent, and had the added effect of making him loose enough that Vergil slid in easily without having to prepare him much.

Once Vergil was firmly inside Dante's body, he would dismiss the sword, and start fucking him, allowing Dante's body a chance to accept him without the pain of him entering.

Thankfully, Dante's spine healed back together after only a few thrusts from Vergil, and Dante whined, the pleasure blanking his mind as Vergil fucked him into the soft bed with long, hard strokes of his cock deep inside him. But he still struggled, he had to stop this madness. He had to-

"You're still tight," Vergil moaned hot and breathily, next to Dante's ear, "Even after all this time." Dante continued to struggle under him, his tail whipping back and forth between Vergil's legs as Vergil continued to fuck him, still trying to escape while Vergil rutted into him. "Even after the innumerable times I've made love to you."

Hearing the words made Dante sick, but he swallowed back the nausea, and instead whined as one of Vergil's thrusts made him see stars. Vergil, ever the bastard that he was, only chuckled and made sure that each other one of his thrusts struck that one position. “If you behave, I’ll let you come first, little brother.”

Once Dante had settled, forcing his body to become pliant under Vergil, letting his elder twin fuck him into the mattress, and not “make love to him” as Vergil, dared claim, Vergil kept hammering at that one sensitive spot inside him, causing Dante’s whines to increase in frequency and noise. Dante quickly came first, spilling his essence all over Vergil’s eggshell blue bed sheets.

Vergil somehow was always able to fight back his own impending orgasm to torture Dante with more mindless pleasure, even as Dante’s body clamped down around him, trying to milk him for all it was worth. But even Vergil couldn't last forever.

Eventually, when Vergil was done, spilling himself deep into his twin's body with a low groan on his lips, and his hand wrapped around Dante's cock, pumping him to yet another completion too, and wrapped his sweet twin in his arms, kissing at Dante's neck softly, and his other hand gently caressing the swell of Dante's abdomen gently, when their hearts were once again in sync with each other, that's when Vergil chuckled.

Breaking the oh-so warm afterglow that Dante didn’t want in the first place, with the noise.

Dante shot him a heated scowl, but Vergil only brushed a loving kiss to those plush, silken lips, his stained hand coming to rub small soothing circles into Dante's stomach and abdomen. "Already, your body begins to accept my claim upon you," Vergil whispered, moving his head so that he could press minute butterfly kisses to one of Dante's ears instead. "You're finally ready to be mine, brother."

Dante hissed, the toxic spines on his tail bristling at Vergil's words. He hadn't wanted any of this in the first place and now Vergil was forcing him to belong to him? No. Dante wouldn't allow it. Vergil's hands continued to circle his abdomen slowly, as the elder gently scraped his teeth against the soft skin at the hollow of Dante's throat, causing Dante to shiver once more, seemingly unaware of Dante's internal strife. Vergil gave a small sigh, and Dante felt as Vergil's mouth twisted into a smile. "I can sense the life swelling within you."

Dante froze as the words washed over him, his tail stilling and spines flattening as his mind pulled apart the words. Life, Inside him? How could this have happened without his knowledge and most importantly Why had Vergil allowed it to continue?

Vergil chuckled again, pulling his head back from Dante's throat to stare down at him, his smile seemingly soft and tender. How could Vergil look at him like that, when he knew Dante didn't love him in the way Vergil wanted him to? "I can hear your mind racing, my brother, my mate."

Vergil, so deeply in love with Dante that he didn't even notice Dante wasn't in love with him.

Dante scowled at Vergil, but Vergil ignored him, instead choosing to press an insistent kiss to his cold lips, before pulling back once more. "You are wondering how your body could possibly sustain life, when you are so obviously male, am I not correct?" Vergil's voice was low, almost comforting, were it not for the panic flooding Dante's mind.

"The answer is a simple one, beloved." Vergil slowly released Dante's abdomen, and moved his hands to his twin's hips, slowly forcing Dante to gyrate against him, a shuddering moan escaping Vergil as he did so, the moan brushing Dante's throat and causing Dante to give off a low noise of his own. "With your transformation, I took certain liberties to insure your devotion to me, my heart."

As Vergil forced Dante to grind against him, he could feel Vergi becoming hard again, and another shudder warped its way through him as he tried his best to maintain his anger at his twin, trying to swallow down the arousal that Vergil was forced onto him, but the pleasure that came with it made it so difficult to keep his mind straight. His own cock was slowly revealing itself against his will with each movement of his hips against Vergil's own..

If Vergil cared about Dante's feelings, he showed no awareness, only forcing his twin to continue to use his existence for his own pleasure. "Your body has taken on some qualities, not unlike certain fish." Vergil moved one of his hands on Dante'ships to slowly glide over his twin's blooming erection as he continued to speak in the same low tones into Dante's ear holes. "Your body now anticipates my seed resting inside you and has adjusted to it."

With each word, Vergil punctuated it with a stroke to Dante's emerging cock, paying no mind to the slime coating it, enjoying the feeling of his sweet other half shivering in his touch.

"Your internal organs are now that of a female, brother mine." As he continued to speak, stroking Dante with each word, he attempted to press a small, tender kiss to Dante's lips, but Dante denied him, turning his head away, so Vergil instead pressed it to his earhole, a small chuckle leaving him, as if he were amused rather than annoyed at Dante's action. "I have designed it to bind us together and to produce our young, even now, my seed quickens inside your womb."

Dante's mouth fell open, unable to stop the rising ocean of pleasure building inside him as his eyes rolled back, him now fully fucking himself into Vergil's fist, Vergil no longer guiding his movements, though Dante didn't notice, his building pleasure causing more slime to soak his cock, it dripping off of him, readying his body to release his own spawn and milt into Vergil's fist, too lost in his own pleasure to notice Vergil guiding his cock into a fabric-lined jar, still encouraging him to rut into it.

Dante's breath sped up as Vergil slowly pressed two fingers back into Dante's colada, gently fingerfucking his opening, causing Dante to squirm, trying to force them deeper inside of him, which Vergil refused to do, instead opting to watch as Dante bit his lip, his entire body going taut as he released into the jar with a high pitched whine.

As he came down from his orgasm, panting and squirming against the fingers inside him that only served to push him into hypersensitivity, he heard the sound of a small glass object being put on the bedside table, but chose to ignore it. What Vergil did with Dante's own eggs was Vergil's business. He'd heard the term "Wealthy caviar" mentioned before.

As Dante's breathing stabilised, he realised Vergil was still talking, and bit his lip, trying to make Vergil fingerfuck him again as he listened. His body craved more pleasure from his twin, and he hated it as much as he craved it.

"...So you see, brother mine, you are now oviparous, like a shark. Your eggs get fertilised internally, and the embryonic development occurs afterwards." If Vergil knew he hadn't been listening, he showed no sign, only gently rocking his fingers deeper into his twin's body, smirking all the while.

Dante gave a quiet sob, his hips undulating against Vergil's hand as he thought about his words, He was pregnant with their children. Dante hadn't wanted this. It was too much. "You will give birth to live young, and I will be there to support you and see them grow." Dante sobbed again, trying to make Vergil's fingers go deeper into his body, but Vergil refused, instead teasing him further into arousal.

Dante didn’t notice as Vergil pulled the jar closer to him again, his dexterous fingers quickly popping the lid and drew Dante into a kiss, before pulling away and shoving his fingers into Dante’s mouth, and quickly covering his mouth and nose, forcing Dante to swallow.

Whatever it was rolled down his throat, slimy and yet juicy, like grapes but smaller. Vergil’s chuckle darkened as he repeated the action, forcing Dante to swallow a small handful this time, and Dante pulled away from Vergil’s grip, a faint, broken hiss leaving him, his tail bristling once more, before his eyes noticed the jar, or rather, the contents of the jar.

Inside, safely encased with the glass were a small pile of his own eggs, softly glowing a dim orange, with red stripes of a swirling essence inside them, all covered by his own milt, and Vergil laughed once more. “Are you so desperate, brother mine, that you would eat your own essence?” Dante shuddered in response as Vergil plucked more from the jar, forcing them into Dante’s mouth. “Eating these will give you energy for our young, beloved.” Once he was certain Dante had swallowed again, he plucked another small handful and shovelled them into his own mouth, swallowing them down without a fuss, before chuckling once more, and moving away, to place the jar on the bedside cabinet and returning to Dante’s body. “You will be so beautiful, so full of us both.” Vergil’s breath quickened slightly.

"We will be a family once more, my mate, my soul." Vergil whispered, his other hand coming to cup Dante's chin and pull it to face his own, "we will be together as one." As he spoke, Vergil moved forward, brushing a slow, gentle kiss to Dante's lips, before pulling back.

"Our young will ensure our legacy, brother mine. You are to be the mother to our empire and army." Vergil muttered, watching with rapt attention as Dante's face once again twisted to agonising pleasure, his cloaca spasming in a mockery of a vaginal orgasm, and Vergil moaned lowly as it spasmed around his fingers, collecting as much of Dante's slick as he could first, before pulling his fingers out to lick and clean them himself.

Dante was captivated, watching Vergil swirl his tongue around those coated fingers, and wishing that Vergil put that wicked tongue to good use, before Dante caught himself and whined as Vergil pulled Dante flush to him, lining himself back up with Dante, and thrusting into him once more, groaning at the soft, liquidy depths of Dante's body.

"You will come to crave my seed as our children grow inside you." Vergil groaned deeply once more, hips stuttering in their thrusts as he grew closer to orgasm, Dante whining with each thrust into him, his own orgasm close to completion. "Your blood and my seed will make them strong, my love, my mate."

Vergil roared once more as he came deep into Dante, before his fangs manifested and he sunk them into Dante's neck, breaking the skin and sinking into that precious glad that bound his half of their soul together. It was an unfinished bond, but Vergil still attempted to coerce Dante into completing it.

Dante shuddered as his own orgasm finally snapped, his mouth falling open, his own fangs itching in his gums, and before he could stop himself, before he could stop the instinct urging him on, he flung his head forward, sinking his own sharp teeth into his elder twin's neck, and deeper still, into the gland. Binding them together.

He had completed the mating bond, as Vergil had known he would, given the right pleasure. Did that mean that Dante had, in fact, came to love Vergil too, in his own way?

It didn't matter. It was too late to change it. He could feel the bond settling in his own body, feel the way Vergil's smugness overrode his own despair.

There was nothing Dante could do.

He was fucked, no matter what happened after, they were bound now, for eternity, or for as long as they both lived.

This was Vergil's true victory.

Vergil had won.

 

 

 

Notes:

This fic was originally going to be called "Appel de la Mer" but in the end, I chose not to call it that while I was searching for information on the sexual reproduction of fish. Did you know that Milt is the term for fish semen? You do now!
