Chapter 13

Dante really thought that he was an extremely experienced person when it came to sex, although that wasn't something he did as often as he used to. As a teenager, when he had the opportunity to have his first sexual partners, Dante certainly took advantage of the good looks inherited from his parents and had taken countless people to bed.

That gave him experiences: few were good, some were average, many were bad. Even in the good experiences, sex was never something astonishing for Dante; therefore, to release his inner tension, he always preferred a good fight with a lot of blood and demonic power on display over a casual fuck, and perhaps that preference was due his demonic nature. He never thought much about it, continuing to have sex when the opportunity arose, but without the same enthusiasm always declared by others.

However, now that he finally crossed that line with Vergil, he understood why people described sex as such a wonderful activity: It was simply breathtaking, and Vergil was the sexiest thing on Earth in Dante's eye. Perhaps the fact that Vergil was a hybrid like Dante was the cause of this immense connection they had in bed activities, or perhaps it was a result of their bonding... Dante wasn't sure of anything, all he knew was that sex with Vergil was incomparable to anything he once experienced with another being, and he couldn't believe how he spent forty years of his life without experiencing ecstasy in its purest form.

Vergil had been much more receptive in bed than Dante could have dreamed, and at the present moment he was facedown, with his rear up and receiving everything Dante had to give him without complaining about pain or asking to stop (something that often happened during sex with his past human partners). Vergil moaned softly, keeping his voice as down as he could, perhaps out of fear of Nero hearing, or in shame of being carried away by his instincts in front of another. Dante, however, wanted Vergil to let it out, because his voice sounded increasingly intoxicating, as did the image he made: Vergil's hair was damp with sweat, and his usual hairstyle was a mess with strands covering his forehead and eyes; Dante could still see the bluish demonic glow of his twin's iris and the dilated elongated pupils staring at him behind the unruly strands of hair; and all that, combined with the feelings he got from Vergil's inner spasms, made him feel goosebumps.

When Dante made a particularly hard thrust into Vergil's body and lowered his face to sniff his sweet pheromones directly by the omega's nape, he saw the satisfied smirk Vergil gave him, showing his elongated canines and making it clear that he was increasingly lost in pleasure as well and that his feral side allowed more demonic traits to escape and tarnish his human form.

Dante loved it, and that was something new. He realized that, even though he never had a desire for the sexuality of demons, he was wrong when he considered that he preferred humans. No, certainly not. He clearly preferred hybrids. Actually, he preferred a specific hybrid...

"Fuck! You're squeezing me so tightly..." Dante practically snarled against Vergil's ear, biting his earlobe when his brother decided to resume his movements and roll under his body in a sensual way.

Vergil was the type of lover that demanded and got what he wanted no matter what, even if he had to fuck himself over Dante's dick. That's why Vergil responded his praise by quickly rotating his body and facing Dante, forcing him to face his rapt and demonic gaze before kissing him lasciviously as he wrapped his legs around Dante's thighs and pulled his penis inside himself again.

"More!" Vergil ordered in a hiss of pleasure against Dante's lips; it was indeed an order, because Vergil was not the type of person to plea. He ordered, and Dante could do nothing but obey his command.

So, Dante resumed his vigorous hip's movements, being greeted by Vergil with the same enthusiasm. He could barely look at his brother in that state without losing his mind: the way he moved beneath him, how he seemed delirious with pleasure at each thrust, the way his body squirmed, how he could see a shadow of his own penis on Vergil's belly, clearly showing that he could take it all without complaining.

Nobody could ever take it all in the past. Nobody. But Vergil could. Because he was made form him! It was all too much to contain his excitement. He couldn't... Dante was losing it!

"V-verg , s-stop! I will -..." He tried to get away, because he still had a little bit of rationality to remember that if Vergil was in heat, he could get pregnant. Getting to orgasm inside Vergil was certainly not a good idea, and his brother would probably kill him if it resulted in yet another unwanted pregnancy at this point of his life.

Contrary to all his expectations, Vergil dangerously growled as he stared furiously at Dante, narrowing his eyes dangerously and wrapping his legs closer around his brother's body, forcing him to keep inside. Dante tried to move away once again, but Vergil simply roared without forming a comprehensive word, showing his teeth in a predatorily way that promised death if Dante tried once again to end their connection.

And then Vergil's tail (which until that specific moment had only participated in sex as an interesting adornment for Dante's new discovery in his 'hybrids kink'), quickly wrapped itself around Dante's neck and pulled him down with enough force to choke him if he tried to get away.

"No! Mine!" Vergil growled against his lips, without even blinking or letting his rigid gaze soften; he was clearly affected by his omega self, "Inside me, Alpha!"

And then Dante, who had been trying for a few minutes to keep himself from reaching orgasm, realized that all his attempts were in vain: the lascivious way Vergil moved below him, rolling his hips as if he owned the world (well, he sure were the owner of Dante's world at that moment) and the way he ordered him around was too much for Dante to handle: he bit Vergil in the neck hard enough to make it bleed and came hard inside the omega, savoring the way Vergil's ass were milking him, hungry for all the cum he had to offer. He vaguely felt his abdomen get wetter for the moisturize to be considered only sweat, and from the way Vergil arched his back and let a pleasant noise escape his throat, it was clear the he wasn't the only one reaching an orgasm.

After they stopped moving, it took them a while gasping for air to catch their breath. When they did, they exchange an intense stare for a few seconds, and surprising every cell in Dante's body, Vergil smiled: he truly smiled, with joy and happiness shining in every millimeter of his face. Dante wasn't able to form words to respond that marvelous outcome. He was so happy, smiling with the same intensity as his brother, so he just inclined himself for a sweet kiss against the pouty lips he loved to taste.

At that moment, Dante concluded that if there was ever a possibility to of having a sex life with another person, that became something impossible after that night he spent between his brother's legs.

And being quite honest, he was more than satisfied with his fate.

When Vergil woke up after a wonderful slumber without nightmares, all the events of the previous night came to mind at once. A mixture of sadness and joy mingled in his feelings, and at the same time that he was happy to have shared such an intimate moment with Dante (with his brother full consent to do so), he still felt guilty for not having revealed the whole truth to him. To make things worse, Nero were still suffering from his disappointment and resentment, and the dread of hurting his cub more became intense. He didn't know what to do now that a new day has raised; all he knew is that reality would come back to haunt him. He had his moment of pleasure and happiness, now it's time to pay the price.

Even so, he has chosen, once again, to postpone the reality. It was inevitable not to do so, not after he noticed Dante's soft caresses in his hair, as well as his calm and contented breath at the back of his neck. Dante hugged him from behind, without purrs this time, indicating that they were both in their purely human form. Dante was awake, taking advantage of Vergil's sleeping moment to engage a soft petting.

Postpone. Yes. And, for that, Vergil decided to pretend to be asleep.

He just wasn't ready to face reality; he would never be (but the reality, sooner or later, always comes to end the dream).

"If you like to get affection so much, you just have to ask, babe. No need to pretend that you're sleeping to be pampered." Dante whispered softly against his ear, making Vergil take a deep breath and turn over on their nest to face him. The two exchanged tired looks from those who had just woken up, but Dante still had a beaming smile on his lip.

Vergil, on the other hand, just frowned.

"Don't call me 'babe', you energumen dimwit." he protested, but he couldn't deny that the pet name gave him butterflies.

"Why not? Do you prefer that I call you 'omega'?"

Vergil felt his face heat in shame. Dante was teasing him because he lost it a little bit and called him "alpha" during mating process.

"Cease this imbecility."

"Your wish is my command, honey." Dante had the audacity to smirk, clearly in a very good humor that morning.

Vergil tsked and averted his eyes, and Dante couldn't contain himself: he just kissed the tip of Vergil's nose (Dante was sure he never saw someone blush so cutely) and waited for a reaction. He noticed that he wasn't the only twin in flirty mode that morning, because Vergil just grabbed Dante's jaw, felt his stubble scratch his bare fingers, and brought their faces together to give a long greeting kiss.

"Good morning, sunshine." Dante said after the kiss ended with a wet smack.

But flirty mode don't last forever: after Dante's audacity, Vergil decided to answer with a fierce stare and spectral swords.

(***)

When Trish opened the door to Devil May Cry, she knew that something bad had happened the night before: she found Nero sitting in Dante's chair, with both legs above the table and looking at Eva's picture with his arms crossed and a grumpy expression plastered in his face, accompanied by big, deep dark circles under his eyes; the boy was clearly distressed, and even someone that wasn't used of being empathic could notice that.

But since Trish was still learning how to act as a human and share warm words to those who were suffering, she just closed the door with a loud noise and put her hand on her waist, tossing her hair to the side as if she expected Nero to get up from the chair and greets her cordially. This, obviously, didn't happen: the boy just looked at her briefly and then stared at the wall behind her like it was the most important think in the room.

"Bad night?" she asked, not caring much about what answer she would receive as she walked over to the pool table and started arranging the balls to initiate a solo game.

"Dante and Vergil were fighting all night." Nero signed, "They're growling and grunting until sunrise. Neither me nor Kyrie could sleep. She just started sleeping a few minutes ago and I had to open the fucking shop, since Dante is a lazy ass and hadn't get up yet." they soon heard a noise of things breaking upstairs, and Nero rolled his eyes, "See? They're doing it again!"

"Typical." she said, as she adjusted the game and grabbed one of the pool cues. "Didn't you try to stop them?"

Trish wasn't stupid. She knew that Vergil was getting closer and closer to a full heat, probably that would happen in a maximum of two days or so. Dante was enduring a long battle with his own nature in a much fierce way than she once imagined, but everyone has their limits. Vergil must've taken advantage of Dante's inner demon; they weren't fighting, they were mating. At least that was the last day of the deal she had made with Vergil, and if the bastard didn't tell Dante the truth, she would have to open up to Dante before dawn.

Feeling a little sorry for Dante, knowing that he always felt terrible after he gave in to his demonic side without his human side consent, Trish took the first shot at the cue white ball and managed to pocket three balls at once. Nero watched her shot, and answered her question so low that even with her demonic hearing she almost didn't get it.

"I don't want to look at Vergil's face anymore." Nero murmured, showing in his tune the sadness he felt, it was so clear that even someone with as little empathy as Trish was able to realize that the boy was indeed miserable.

Trish stopped playing and leaned on the pool table to stare at the boy a little more. She was briefly curious about his apparent melancholy, since she thought that Nero would be better today after his discussion with Vergil. After all, there wasn't rational to be saddened after learning that Vergil was his parent in a slightly 'different way' than he had previously imagined. As it seems, humans could be particularly sensitive and hybrids apparently took that characteristic to themselves.

"I suppose it was not only Dante and Vergil who fought yesterday, right?" It was a rhetorical question, because it was evident that Nero and Vergil had also had a disagreement.

The boy didn't answer as he kept averting Trish's eyes; she was sure he was trying not to cry, because Nero's eyes shined with unshattered tears, and maybe if he look at her, he would lose this battle.

It appears that all the Sparda boys see me as Eva, intentional or not.

That thought was something that Trish despised, but this time she wasn't angry about it. Indeed, she was really mad when V opened his heart to her, probably because she has the twins' mother face and that made him trust her to the point of feeling comfortable around her. She didn't want to be Eva's replacement, specially to V (or Vergil, as she had learned at that exact moment who were his real identity), but it was inevitable. Dante also had this kind of behavior around her sometimes. Maybe something in Sparda's DNA made them all see her like Eva, and Nero trembling lip and evident show of emotional weakness was proof enough that he also saw her as such – since he wouldn't cry in front of someone that wasn't his family.

This conclusion made her feel cared for and appreciated.

I can't be the grandmother he wants and deserves, but I can be a friend.

"Come on, Nero. Let me help." She asked in the sweetest tone she could muster as she approached the table.

Nero finally stared at her eyes and started to blink fast, trying to suppress his tears. He managed to do that, but the wet shine in his blue eyes were still caught up by Trish.

"I just don't understand how he could leave me." he explained in a saddened tone, "Kyrie is pregnant and I don't think she could ever leave our baby. How could he?"

"As far as I know, this isn't new information, but you didn't seem so sad about it in the past. Is there a reason for this to be a problem now?"

"He..." Nero swallowed and breathed hard, but that didn't help his voice to sound broken as he spoke, "He spent months pregnant of me and still abandoned me. Kyrie wouldn't do it to our kid, she would find a way. I know she would."

"Ah, the human fairytale about pregnancy and love that conquers everything. Got it."

She had read something about it. Humans overestimate pregnancy and motherhood, they think it's the woman obligation to love their kids no matter what, and the father's love are often described as something lesser than mother's love.

"No, that's...-." Nero tried to explain, but couldn't. Because that was exactly what he was thinking about, even if he wouldn't admit outloud, "Look, all I'm saying is that he made a completely rational choice. How could he not be driven by emotion after all he had to go through during pregnancy?"

She hummed, thinking about Vergil and the choices he had made in the past. Nero was wrong, and she would prove him that.

"To tell you the truth, you're lucky that Nelo Angelo didn't try to kill you when you were born."

"What?!"

Well, if he was waiting for sugar coated words from her, he was going to be disappointed. Trish was direct and effective, and that's the only way she could help him.

"If Mundus had found you before Dante defeated him, you'd be screwed." she shrugged, since it was obvious that Nero as a kid had no choice against the Prince of Darkness, "And by that I'm not saying that he could just kill you. It probably would be worse: he could use your power against the twins and only after that kill you in front of their eyes. That's why Nelo Angelo used his heart in this choice when he left you in Fortuna, because killing you before Mundus got you would be the easiest route to go. It would be safer for him and Dante if he did that. Therefore, he didn't choose the safer option. His heart didn't let him choose the safer option."

That was the first time Nero considered that Vergil had a third opinion: he could stay with him and risk Mundus finding them, he could leave and hope for the best for his cub's life, and he could've killed him to avoid any tragic fate that could've happened if he didn't. The third option were the rational one: if he wanted, Vergil could have another cub in the future after he destroyed Mundus (since that was his plan all along), and Mundus wouldn't be able to take Sparda's power in any form because there wouldn't be an offspring to be used.

This new scenario made him stop talking and think for a while.

Does Vergil really feel something for me?

"Maybe you should have a little more empathy, Nero." Trish said after it became clear that Nero didn't have any words to respond her, "You suffered the abandonment, I understand that. But as hard as it is to believe, I think Nelo Angelo suffered a lot too."

Nero frowned.

"Are you defending him? I thought you hated him."

"Just a little bit." She winked, and that made Nero show a small smirk, as if he could understand what was like to hate Vergil 'a little bit', "I just have to be fair here: Even if I hated Nelo Angelo with all my heart, I wouldn't be able to lie to you and say that he doesn't have any feelings towards you; I heard your name escape his lips so many times that it would be stupid to consider otherwise."

Nero showed confusion in his body expression, dragging the chair and transforming his posture into a more rigid one.

"What are you talking about?" he asked, afraid of what kind of revelations Trish would give him. Because he knew that he would learn stuff about Vergil's past that maybe would be hard to comprehend.

"Haven't they ever told you? I was part of Mundus' torture against the eldest son of Sparda." She said casually, and ignored the way Nero's eyes expanded in completely surprise, "Why do you think I look like Eva? Mundus created me like that and used my appearance to torture him. During his mental delusions, he repeated 'Nero' more than he repeated the names of Dante, Sparda and Eva, but in such a lingering way that it was difficult to understand what he was talking about. It sounded like 'Nelo' many times, and that's why Mundus named him Nelo Angelo. It's a really cruel thing to do, naming someone after a person that was important in your life. Mundus thought 'Nelo' was some lover that Vergil had in the past... It never crossed his mind that he could be a cub named Nero. His body didn't show he had had a litter."

Litter?

"Wha-...?!"

But Trish didn't stop talking, and whatever Nero wanted to ask was simply ignored.

"You see, demon's intimacies are fragile and don't regenerate like the rest of their bodies, so it's easy to identify a demon that has already given birth. Nelo Angelo must have done something very painful to keep you from birthing by conventional methods, and he did it to not leave any trace of your existence if Mundus captured him. He was a tough guy, I must confess. He was strong, he never showed weakness other than the mental torture that Mundus did. Physical torture and rape never made him even sigh in pain."

Nero felt like fainting. He simply opened his eyes wide and stared at Trish for long seconds, pale, not sure what to say after receiving all that revelation. He knew Mundus had done something to Vergil, but he didn't know all the details and had even considered that it had gone to that extend... Oh, he was sick just to think about it.

Trish, realizing by Nero's reaction that she had probably crossed the line when she touched that particular topic, prepared to try to soften the situation a little bit. Maybe Dante had his reasons to not tell all that to Nero. Maybe that was something that should be sugar coated? Oh, it's so hard to understand human morals!

But before she could repair any damage she had done, Devil May Cry's front door busted open.

(***)

"You just have no sense of humor." Dante nagged as he massages his ribs that were almost healing from the wounds done in the latest fight.

Nothing like a morning combat to start the day in the right track. – He thought, smiling to himself. Oh, how he missed being able to fight Vergil over nothing, just to fluster him! And, on top of that, now he could give him little pecks when he got the upper hand (which resulted in more and more punches, but that's beyond the point).

"Your definition of 'humor' lacks refinement, brother." Vergil scoffed, laying down onto the bed once again as Dante sat right next to him in an aloof manner.

"Yeah, yeah. Right." The younger rolled his eyes, but soon enough adopted a serious posture, staring intently at Vergil, "So... Even if you do show happiness in your own way, I noticed you are a little rusted. Thinking too much, aren't you?" He asked as he slid his hand over Vergil's thigh that were now (unfortunately) covered by his pajamas' pants.

"Yes. You should do it sometimes, if your brain is able of doing a mental exercise." Vergil grumbled, smacking Dante's hand away.

"You hurt my feelings, sweetheart..." Dante pouted, waiting for another fight that never came. Finding the lack of reaction strange, he looked more closely at Vergil's thinking expression, and asked in a concerned voice, "Do you regret what we did...?"

Vergil, not quite sure how to answer that question with words, just pulled his brother back to lying down position and intertwined his legs against Dante's, while proceeding to rest his head in the fold of his brother's neck and chest. Dante gave a low, satisfied giggle, and returned the closeness by pulling Vergil's body closer to him in a loving hug.

"I think that's your way of saying you don't."

"Hm."

Dante knew this was as close as he would get to Vergil's positive answer and, satisfied with the way he seemed more receptive to affection that morning, just kissed his messy hair and allowed himself to enjoy the embrace for a few minutes of silence.

But, surprising his brother, Vergil interrupted his daydreams.

"Do you regret it?" Vergil questioned, after almost ten minutes of silence.

"No." Dante replied without thinking, because it was absurd to think otherwise. He pulled Vergil's face away to look him in the eye: he still looked tense, his eyes were slightly widen, as if he were afraid of every word Dante might say; "What's the problem?"

"You wanted to get away from me and I didn't let you." He said in a cold voice, probably judging himself and his past actions.

Dante just smiled, satisfied that Vergil was concerned with his well-being. He didn't have to be, though... Dante loved every moment of it.

"Ah, yes. It was fucking hot!" he winked, loving the way Vergil's eyes bugged even more in surprise, "Do that more often, spank me if I am being naughty and disobey your command, master."

"Dante!" He censored, and Dante felt giddy that he was able to embarrass his mate again. It was refreshing to be the one able of doing that (since Vergil was the one embarrassing him every time until a couple of hours ago). "I'm being serious! I don't want to force you of doing something you don't want to do."

"Hey, chill out, Verg. I wanted to get away in the end because you're in heat and, well, we didn't use protection. But if I really wanted to leave you, I would have been much more reluctant. You know I didn't even use my real strength."

Vergil seemed a little confused over this answer, but soon enough he must've concluded that Dante was just an idiot, because he rolled his eyes and shook his head in denial.

"I thought you knew hybrids don't get human's sexual diseases."

"No, no! Of course I know that! What I mean is... Uh...Nero is already a little big to play with a little baby brother, right?" Dante explained, now feeling a little shy.

That made Vergil stop moving for a second, as if he was processing something really difficult to understand. After that, he just said in a weak tune:

"Oh." he signed deeply and closed his eyes, as if protecting himself over something, "This is an impossible outcome. Don't worry."

"What do you mean?"

"I cannot provide another offspring to Sparda's lineage."

Dante frowned.

"Now you are being stupid. Trish used to say that we should be sterile because we are hybrids, but I think the fact that Nero exists isn't due to a 'divine miracle'. And even if you act like a crooked old man, your biology is responding like a quite fertile omega."

"That's not it, Dante." Vergil answered in a neutral tone that made the younger suspect that something was being kept from him, "I was able to have cubs before, Nero is the proof of that. But after everything that happened... I'm now incompetent as an omega in this aspect."

These words hit Dante like a bomb: he knew that something bad must've happened to Vergil and he was just acting like nothing was a problem. Vergil tend to do that: put on a poker face when he was feeling hurt or sad, using an ice tune to hide his feelings and fears. Even if Dante couldn't feel Vergil's emotion like he did with Nero, he could see that something was off.

"Vergil... What happened?" His voice sounded frightened, because he wasn't sure if he wanted to know the truth.

"I do not want to engage such meanness conversations about past inconveniences that cannot be changed."

Oh, fuck, now I do want to know what the fuck happened!

But before he could demand that Vergil spit it out, the bedroom door was forced open by and angry kick. Suddenly the twins weren't alone anymore, and neither Nero, nor Trish, was the identity of the invader.

... To be continued...

Omegaverse observations so far:

Demons spawn only one demon per pregnancy. The twins were born in the same gestation and that was something atypical, but it was only possible because their mother was human.

Demons are either omegas or alphas, and this definition does not depend on the demon's gender (female, male or intersex). Regardless of their gender, omegas can become pregnant.

Omegas are usually subjugated and enslaved by alphas' power. The omega who tries to break this cycle, usually end up killed by the alphas.

Alphas fight with each other for territories' domination and to court omegas. The omega's heat affects the alpha as well, causing these alphas to become especially energetic when they are close to omegas in heat, to protect them and supply them with energy.

Omegas, during their heat, lose a lot of energy and need physical contact from an alpha so that the two can balance their energy levels. The exchange of energies' speed are intensified with the carnal contact, but the corporal approach is enough for this exchange to slowly happen.

Omegas that cannot obtain the energy of others during their heat dies.

As a consequence of this energy's need for survival, omegas are able to charm humans so that they can obtain energy in the absence of alphas to supply this need. Such power apply only against humans, which created the legend of succubus and incubus in the human world. (Observation: that means Vergil was able to charm Dante in the cemetery scene because Dante is a hybrid, so hybrids are also susceptible to this power because they are part-human. He cannot enchant a pure demon, though, and Dante seems to be less affected by his enchant by each chapter).

Hybrids have dynamics slightly different from pure demons: they acquire their needs from the demonic nature after their first devil trigger. Dante, however, only started to feel the effects of his alpha side only after acquiring his sin devil trigger (at least that is what it seems up to that point in the fanfic). The reason for this and more details about the difference in puberty moments between the three hybrids will be clarified in future chapters.

In a demon pregnancy, the pregnant omega/human need to obtain energy by someone, usually his alpha mate, to generate a heathy cub. In case they don't get the energy, the omega/human will be weakened and the pregnancy may suffer some… complications.

Regardless of being an omega or alpha, a dying demon has two options: become a devil arm and submit his power to the one who conquered him or, if his will and pride is strong enough, be reborn in the Underworld, but in a weaker form without the power he previously possessed. This is what happened to Vergil after Dante killed him in his Nelo Angelo form.

Any doubts? Let me know!
