Work Text:

~~~~~~~~~~~

The days after what some humans called 'Armageddon' were both chaotic yet anticlimactic for many. It was never supposed to be a war between anyone at all, just the end of the agreement that demons wouldn't roam the Earth.

With the seal finally gone, demons and creatures of all shapes, sizes, and colors came out quite casually; introduced themselves to the heads of the area they emerged into, and thus began their new lives integrating into society.

There was some resistance, of course, but other than the random scuffles and 'crusades' it wasn't particularly effective in stopping anything.

Slowly, buildings of businesses run by the demons began to open across the world. Anything from clothing and accessories to strip clubs and burlesque houses, each one unique and very successful.

This store in particular was especially unique even for demons.

Half 'n' Half coffee was much more than a play on words. You see, the owner was what some would call a 'half breed'. His father, Enji Todoroki, a very powerful and pompous fire demon that usually went by the moniker 'Endeavor', had long ago captured an Ice dragon and had been breeding her until finally Shouto Todoroki was born.

Able to use both fire and ice at once, and shift forms easily between demon to dragon to human and back, had made him the perfect tool for Endeavor's plans to climb the ranks of Hell but...Shouto didn't care to do such things, instead choosing to go out of his way to humiliate his 'Father' in whatever way he could think of.

Which was how this place came to be.

A place where 'lowly' humans and other 'lesser' half breeds could mingle and enjoy the drinks and treats he and his staff made in the front...and a bdsm dream in the back.

Like most shops, this one had a 'Special of the Day' board with drinks mixed with very special naturally made cream, each named after the individual that created it.

With a cup of half coffee, half personal cream, the drinks had become very popular amongst humans and otherwise, though not many knew what exactly they were actually drinking.

With a flip of a switch, a loud hum, and a very strange noise from behind the wall, a large gush of off white colored liquid would come pouring out into the mug before he flipped it back off and mixed the coffee in to serve it piping hot.

Based on the amount that came out, he would know if he was going to end up having to whip up some special desserts later to use up the excess flow.

Not that anyone complained at the end of the day.

You see, every worker that volunteered to be on the 'Special of the day' board was placed in a specially made and very comfy milking chair. Granted it took the first timers a while to get used to sitting on the stimulator rod but he designed it to be flexible enough for maximum comfort. Once seated, strapped in, and situated, they would then have to wear a gag so as to not bother the customers with their noises and a cock ring absolutely covered in his personal magic sigils to hold back the flow till their respective drink is ordered.

Basically, they signed up to be edged for five to eight hours a day with random orgasms depending on the customers.

At the end of the day, he had them release every drop into his special collecting jars for the ever popular baked goods and sweet treats he also sold before making sure each person was treated to some special aftercare either by him or the fellow staff members. 

With all of his calm, calculating, powerful, and dominant aura, one would say he was an alpha demon, but to everyone's shock, and his father's shame, Shouto was actually an Omega prime, able to keep meticulous control on not only every aspect of his nature but also keep order with even the most volatile alphas around him.

Who knew so many alphas craved the 'humiliation' of an omega being the one to Dom?

Still, even with the perverse joy of watching humans drink cum coffee, some days Shouto found himself bored and tried to find ways to entertain himself as the hours passed.

The most popular of the ways was guessing the mix of the half blood customers that came in.

It wasn't particularly a challenge for him, his sense of aura and smell was next to none in accuracy, but it was fun to try and imagine how the mix occurred. How did a merfolk meet a Minotaur? How would they mate? Did they stay together to raise their child or was it like most cases where one left the other parent and child behind? 

He had passed many of his days coming up with silly theories as romantic stories in his head but one day, a customer came in that stumped him.

The first to step in were two half breeds that frequented his cafe quite often; a short blonde incubus/lightning demon with a small black lightning bolt in his hair named Denki and a short pink afro haired, small horned, pink skinned succubus/acid demon named Mina. Then walked in a very tall, slim, black haired, black eyed man with large elbows and an even larger smile that in every way seemed like a plain and ordinary human…

except for how Shouto's senses started to tingle otherwise.

He stared at the newcomer, so lost in thought he didn't even realize the group had approached the counter until pink fingers snapped in front of his eyes and he blinked.

Though startled, his outside demeanor merely turned towards Mina who wore a sly grin and a raised eyebrow as she asked, "Zoned out today, Shouto?"

"Apologies, Mina." The response was automatic but helped his distracted mind slip back into work mode. "What can I get you today? The usuals?"

The way the shorter two licked their lips in response was an answer without words but the pair wouldn't be them if they didn't enthusiastically respond with the usual, "HELL THE FUCK YEAH!"

It honestly made him smile just the tiniest bit at how much energy the two could radiate so easily for something so simple but once his eyes returned to the very tall third of the group, his mind blanked once more, his senses absolutely delighted at the odd feeling the man gave him.

Thank the divines for his years of customer service as his mouth calmly spoke, "And you, sir?"

Before the man could reply, the other two lept up to wrap an arm each around his shoulders to cause him to bend forward a little from the combined weight with a very light, very pleasing laugh.

Did his inner self just purr?

Denki responded first, "This guy is our human friend, Sero! He goes to college with us and we thought it'd be fun to bring him with us to try a drink!"

Mina nodded along as she quickly added, "It's gotta be your best one though cause we promised it would be!" She leaned with a wink, "Not that anything here isn't top notch, of course!"

Both dissolved into giggles as the man, Sero, finally got himself out from their hold to chuckle himself and hold out a hand. "Hey! So you're the one these two can't stop bothering about, eh?"

This entire exchange filled Shouto with confusion as he shook the hand firmly and responded, "I suppose?"

The touch lit up his senses even more fiercely than before and it took a great amount of effort not to grip the hand harder and instead let go.

This man can't be human.

But really it wasn't his business. "What would you like to try today? I have many kinds of baked goods and drinks you could sample but if you have a preference on flavor, I could try and suggest something to the taste."

 

~~~~~

 

Ok, so maybe Sero thought his friends were exaggerating when they told him all about the 'sexiest barista alive' and maybe he thought he was being set up for some mischief for their amusement as was a usual occurrence…

But DAMN if this guy wasn't absolutely beautiful.

Cool, calm, collected, yet obviously had at least a small sense of humor if that tiny smile at his friend's antics meant anything.

Shorter than him by a foot with long two-tone red and white hair braided together down his back, two tall horns on his head, one like an antler made of snow, the other a slightly crooked goat horn, one red eye, one pale blue eye, smooth, pale skin except for a burn on the left side of his face that only seemed to add to his allure…

All in all, waaaay out of his league in every respect.

Seriously, how could a bland human ever even dream to attract this guy?

So, with full understanding it wouldn't go anywhere (even if touching hands left his hand tingling), Sero decided to see if he could at least fluster the guy, 'Shouto' Mina had said, with a little flirting. Maybe they could be friends!

He shifted to read the full menu and his eyes locked on the 'specials' that his friends were so addicted to.

"Usually I'm a citrus guy but walking in here and seeing your beautiful self, I find myself craving the taste of peppermint." Grin wide with mirth, he leaned in a little and winked as his friends snorted with muffled laughter behind him. He knew it was ridiculous and only after he had done it did he realize he could have just made Shouto uncomfortable…

Till a small smirk pulled at the corner of those sinful lips.

Oh fuck, Sero had to fight to keep himself relaxed as he watched the other lean a little closer as well. "Is that so? Well we have lots of peppermint snacks and drinks that could help that sudden craving."

Sero listened intently as Shouto went through the list, more enjoying the voice itself than what was actually being said until Mina piped up, "He'll take the IcyHot special!"

Both guys turned to look at her with a blink before Sero tilted his head. "IcyHot?" He turned to look back at the beautiful barista with a raised brow.

 

~~~~~

 

Ever get that feeling like someone is trying to start some chaos while they drag you into it?

Shouto's eyes studied the pink demon for a moment, very aware something was in the works here that he wasn't catching just yet though admittedly, he was having a little trouble keeping his thoughts in order.

He was used to folks paying him compliments, as that's normal banter at places like this, however this time...his heart actually fluttered a little. 

The casual, relaxed demeanor (which was a sharp contrast to the two live wires of energy behind him) mixed with the ease the flirt was spoken, truly caused him to feel both relaxed and nervous all at once.

"Everyone here has a nickname they go by for marketing reasons and some of our drinks are listed by those names as it is a mix of the desired normal drink mixed with some cream created by the person named."

As he spoke, he moved to get a mug, and walked over to the tap wall that had the name of each drink listed above the respected tap. "For Mina, she has started to favor 'Real Steel' over the others." 

He twisted the tap, the loud hum and noises sounded, then the cream poured before he turned it back off, mixed the drink to it's steaming perfection, and set it on the counter before Mina.

"Denki has been happily rotating through the flavors but anytime we get someone new…" The chosen tap was labeled 'Insomniac'. "...he absolutely must give it a taste."

Both demons paid immediately and took a huge gulp before making the most sinful sounds of delight as Shouto noted Sero reading each of the names.

 

~~~~~

 

A long wall of flavors, each with intriguingly unusual names but…

"I don't see IcyHot listed…" Sero felt his confusion push on his mind as he turned to look at Shouto for answers, unaware the answer was literally right in front of his eyes.

"That's because 'IcyHot' is me."

Well then yes please Sero would like that very much and in the largest cup possible, or a bowl, or a bucket or- "Oh yeah! That makes sense!" Bless his casual autopilot for not giving away his inner gay panic. "Then I'd love to try it! Perhaps as a hot chocolate? I don't drink coffee all that much…" His voice trailed off as he realized the other...was actually blushing! It was the slightest tiny bit but it was definitely a blush! Yus!

He watched as Shouto rang up the purchase before he paused to say, "It will take a few minutes as it's not on tap. Are you ok waiting?"

"Oh! Absolutely! Just builds anticipation." He winked again before paying and sitting with his friends who were drinking happily and who immediately started teasing him.

Yeah, he was attracted, yeah, they were right, and yeah, he wouldn't mind getting to know the guy but…

he's still just a plain human guy.

 

~~~~~

 

Having one of the prep staff man the register, Shouto went to the living quarters of his building, down a flight of stairs to his room.

Normally he would have to really work himself up to be able to produce the cream needed but today...today he was shocked to discover he was already half hard.

There absolutely has to be something mixed in Sero's blood to be calling to his own like that. The scent he couldn't name, the tingling he couldn't explain, the way he felt his aura reaching up to the ceiling in search of the other man. All of it led to something he hadn't been sure he would ever experience in his very long life…

Attraction.

An actual desire to mate.

His inner self purred and crooned softly as he undressed and wrapped a hand around himself, jerking himself off quickly to the most surprisingly powerful climax he had felt since his first heat, all while the image of Sero's flirtatious smile chuckled in his head.

Oh.

He made too much and overflowed the cup.

Oops.

 

~~~~~

 

"Soooooo, ya gunna ask him ooooout?" Teased Mina with a wide grin.

Sero just leaned back in his seat and relaxed while he smiled back. "Nope." He even popped the end of the word for effect.

Instantly his friends pouted and Denki whined. "Awwww come on, man! Why not? We can tell you're attracted, you know?" The blonde pointed to his nose. "We can smell it, even with your barely there scent!"

Shaking his head with a laugh, Sero waved his hand at his friends. "One sided attraction isn't a good reason to make a fool out of myself. He doesn't strike me as a guy to date just anyone and that's perfectly fine. Maybe I'll invite him to read mangas someday or something platonic but that's not something you ask someone you just met."

Both demons tilted their heads and asked, "Why not?", to which Sero rolled his eyes and laughed. Of course sex demons who would bang a person they just walked past wouldn't understand the human way of basic interaction.

Suddenly, the most delicious aroma he had ever smelt in his entire life hit his nostrils and he reflexively inhaled deeply before turning his head every direction to locate the source. "What is that...smell?" 

It was...sweet? Soothing yet spiced? He struggled to really identify it but his entire world had narrowed to locating it.

The confused sounds his friends made were completely ignored as he slowly stood and sniffed.

He felt something inside himself shift, something that made his heart start to beat quicker, his breathing to deepen, and his ears to ring…

Until he heard Shouto's voice call, "Your drink is ready, Sero."

Reality snapped back all around him and made him have to hold his head and the back of a chair as a wave of dizziness hit him. 

"Sero?" Denki's voice was concerned as he placed a hand on his shoulder. "You ok? You sort of zoned out there, buddy!"

Still a little dizzy but somewhat back to normal, Sero turned to his friends and smiled. "Y-yeah, I'm good. Not really sure what happened there but hey, my drink is ready!" He forced himself to stand and walk to the counter to get his drink as he tried to calm himself from what he figured must have just been some sort of panic attack.

 

~~~~~

 

Shouto's senses were screaming that something was off.

He didn't know what had happened while he was...occupied...but in that stretch of time, Sero's energy shifted from a calm, barely there to agitated, confused, and undulating.

"Are you alright? Did something happen while I was gone?" If someone caused this shift, well...it wouldn't be the first time he had to eject some ass for starting shit in his cafe.

But then Sero smiled and laughed. "Oh, yeah no I'm ok! I think I just had a blood sugar dip or something. Nothing a good drink can't fix, right?" He winked as he lifted his tall cup, said, "Thank you for the drink!", and returned to his table.

Eyes still studying the man, Shouto inquired to his front staff for any information but only felt more confused after they told him how the guy had just randomly stood up while looking all around for a few minutes straight before his friend got his attention.

It was shortly after he watched Sero take a large sip that something inside him clicked.

"Well shit. We're closing early today."

 

~~~~~

 

"Really guys, I'll be ok! I guess I didn't eat enough for breakfast or something that's all…" Sero assured as his friends continued to eye him. He really wasn't one to make a scene or make folks worry about him and knowing he had done both made him a little embarrassed. 

At least Shouto hadn't seen what happened.

He turned the cup around between his hands on the table and studied it. It looked like normal hot chocolate and the heat was nice on his fingers but something inside him felt strange.

Restless.

Eh, whatever.

He lifted the drink and took a sip.

Which became a gulp.

Then a larger gulp, till he was practically chugging the drink down without even taking a breath.

Holy fuck it was delicious! The best thing to ever hit his mouth! Honestly something inside mourned the chocolate taste over the other, sweet, thick flavor that had to be Shouto's special cream!

He couldn't get enough of it!

He shoved his face harder against the rim of his cup, crinkling the cardboard like material it was made of as something deep inside of him stirred. His eyes were closed so he couldn't see his friends' shocked faces or the panicked customers being ushered out quickly by staff. His ears were ringing so he couldn't hear the yelling voices all around him or even his own deepening growls. 

All he could smell was the drink.

All he could taste was the drink.

And he felt amazing.

….till the cup was empty.

Only then did his eyes open to reveal they had both turned a solid shiny black, no white at all, his usually perfectly straight teeth aching as they shifted to much sharper fangs. His chest rumbled deep as he locked onto his friends and smiled.

He knew them.

Friends.

But friends smelled...afraid?

He frowned.

How did he know that?

His eyes shifted to see others surrounding them.

He did not know them.

Inside a voice growled 'Danger. Protect.'

Slowly he stood between his friends and the others and loudly let out an odd, very threatening clicking sound.

 

~~~~~

 

Even through the chaos, Sero's new, nearly overwhelming scent made Shouto's inner self sing to the point he had to struggle to keep himself in check before anyone accidentally destroyed his cafe.

With a great amount of focus, he released his omega prime scent of calm across the room which caused everyone that wasn't wearing a scent blocking mask to melt into their seats or to the floor.

Everyone except Sero.

Instead of sinking to the floor, the ravenette's body turned and obsidian eyes locked onto Shouto as he took large inhales of the scent.

The clicking shifted from angry to soft coaxing as Sero slowly made his way towards him.

The masked emergency staff went to stop him but Shouto raised a hand to stop them. "I will lead him down to the rut room and lock him in. Someone run down there now to make sure there's enough provisions for a long stay as I imagine this is his first time. Do Not Touch Him."

The last words were not intentional but he wasn't going to correct them. If his inner self didn't want Sero touched enough to voice it through him, then he wouldn't be touched.

Luckily for everyone, Sero was still more or less in human form and seemed to be struggling in his movements as he slowly followed the sweet scent through the lobby, the kitchen, down two flights of stairs, and into a gigantic dark room.

Shouto knew he had to be careful. A newly presented alpha was usually predictable and easy to contain but this was such an unusual situation that he wasn't sure that he could depend on that knowledge now.

Especially when his inner self was having such a strong reaction like that.

Slowly he guided Sero to a large pile of comfortable blankets. Not exactly a 'nest' per say but a good enough bed for whatever size his true form was. 

"Sit, Sero." His voice was firm but not fierce, his years of handling Alphas in all states of mentality had long taught him the correct tone to use to instruct but not challenge as he watched the man carefully sit and reach out for him.

"Mate."

Sero's voice was deep and hissed just a tiny bit with clicks crooning out trying to call to him to be closer.

He really wanted to answer that call.

But…

"No, Sero. Stay here."

 He slowly made his way backwards to the door but each step only agitated the other as he slowly rose back to his feet.

"SsssssmMatesssStayss" the clicks got louder as his body struggled and twitched to contain itself enough to follow.

"Stay, Sero." 

He was at the door already and knew by the time the other made it there, the door would already be sealed.

So he turned away to give orders to the others.

Admittedly, that wasn't the smartest thing to do.

Never assume, as they say…

There was only a moment when he felt himself bound around the waist that he could say, "Oh!" before he was yanked into the chamber right before the heavy door sealed shut with a ward that wouldn't allow the door to reopen until they sensed the rut was finished.

Immediately his emergency staff opened the food slot to call inside but were surprised to hear Shouto's normal voice call back, "I'm fine. Take care of the mess upstairs, get all the information on Sero as you can from his friends and prepare proper meals and hydration for us both."

The staff hesitated to leave for just a moment but the repeated assurance that he was fine finally had them scattering to follow his orders.

Then he turned to face Sero who had him pinned to the bed, clicking and rumbling happily as long glowing tendrils extended from his body to float out around them. 

A clawed hand brushed his hair, now free from the braid, out of his face as the clicking voice crooned, "ssPreettyssss"....and ok, maybe Shouto preened a little at the compliment but he needed to keep control.

"Sero, are you still conscious in there at all? If you can hear me, I need you to unbind my waist so I may stand."

 

~~~~~

 

Pretty mate, pretty, smells good, soft, powerful, good mate, yes...

Sero's mind was filled with powerful, loud words and impulses he couldn't fully understand but knew he had to do. This strange presence hadn't been gentle in its takeover of his senses, no, it was as if a dam had burst and the part of him that was held inside threw him aside to take control.

Perhaps it was revenge for being denied for so long.

Still, he could sometimes hear outside words, catch glimpses of outside images, almost everything was... him.

Shouto.

Everything was calmer when he was close. Everything felt better when they touched.

He wondered why…

"Sero?"

His name! Yes! Well...part of his name...for some reason it irritated him to be called that by the other.

He didn't want to hear that name right now.

He wanted to hear…

"Ssss...H...Han...ta...sss"

His voice...was that his voice? Had to be. He felt it in his throat.

What was wrong with him?

His skin felt tight while everything inside felt too hot and wriggling like something wanted to come out, split him at the seams, yet none of it was painful.

Quite the opposite in fact.

The energy that thrummed through him was...liberating.

Powerful.

Borderline euphoric.

No drug he had ever taken had brought him so high.

A touch to his face, cool and comforting, brought his mind back to focus a little.

His mate was talking.

Mate?

The happy thrum in his mind agreed.

"Did you say...Hanta?"

His name! His actual name! The pure bliss of joy was nearly orgasmic all on its own!

He must have made a happy sound as his very pretty mate smiled a tiny bit. Mate is pleased with him...mmmm gooood wait…

"Hanta." Ahh how he could listen to that voice say his name 'fiveever' as friend would say...friend? He meant Denki. "Focus on me. I need you to unbind my waist and other arm for me, ok? Will you do that for me?"

Mate wants something...unbind?

His eyes slowly lowered to really look at the man below him and wanted to blush. He really had mate pinned down, didn't he? He should really let him up n-

A powerful surge of angry refusal slammed into his senses and he cried out in pain.

OUR MATE! NO RELEASE! OURS!

He lifted his hands to grip his head tightly, unaware of how his body jerked up and backwards as he screamed and struggled on the ground.

STOP! PLEASE! he tried to yell but his mouth refused to form sounds beyond his clicking shrieks. Tears poured out of his eyes as he fought against the attack, his arms and legs suddenly grabbed tight and pulled into a dark swirl inside. HELP ME! PLEASE HELP ME!

 

~~~~~

 

To say Shouto was surprised at the sudden display of agony would be the very least way to describe the emotions pumping through him.

The sharp change from happy content Alpha to painful distress brought his inner self to the forefront of his mind in dizzying speed.

Alpha hurts! Must help!

And as he heard a softly whimpered "...h-el...p.." through the other noise, he knew he absolutely agreed.

Using the tiniest trace of fire magic he could, he burnt through the bindings himself and carefully approached the other.

He would have done so much sooner but the risk of provoking the Alpha was too great, especially with how at odds the two sides seemed to be.

With hands on either side of Sero-no, Hanta's temples that were drenched with sweat, he focused his scent to calm as he spoke softly but clearly, "Hanta...Alpha...calm…"

He watched the man struggle and thrash about, eyes wide and unseeing in panic, mouth openly displaying how all his straight teeth had turned to razor sharp fangs, the glowing tendrils lashing out every direction yet somehow never once near enough to harm him.

He leaned down and pressed their foreheads together, using his magic to try and reach inside. "Hanta…"

Inside was understandably chaotic.

Swirls of black, white, yellow, and purple all colliding and twisting around as he carefully flowed through to where the life force was strongest.

There he saw Hanta strung up naked in what looked to be a web! Arms stretched out to the sides, head hung limp, and legs wrapped together like he was hung on a cross, all the while a massive, multi-legged form scuttled about in the shadows.

Also Hanta had one of the longest dicks he had ever seen but he couldn't let himself be distracted by that just yet.

Well now Shouto knew one answer, at least, though he had never known a spider demon to act so aggressively outside it's own territory.

Then again, they are known to be quite possessive and if the demon consciousness considered him to be their Mate, well...perhaps the aggression wasn't so surprising after all.

With the natural calm he was born with, he slowly approached Hanta's form, confident he wouldn't be harmed by the other in doing so. In fact, his very presence there seemed to calm some of the demon's agitation though the clicking was still angry. "Hanta? Can you hear me?"

The slight groan was honestly a relief to hear. "Sh-Shouto?" The normal black human eyes opened as his head lifted to look at him. "Fuck, man...what's going on?" The poor guy's head turned to take in the swirling energies around them. "What was in that drink?"

With his hot and cold hands, Shouto took hold of the other's face and locked eyes. "Hanta. Focus and answer me clearly. Did you know you have demon blood?"

Confused black eyes blinked at him. "Uh...no? I'm just a human, dude. Human parents with zero demons in the line. I mean, yeah, I'm the tallest of the family but I eat my veggies and drink milk." All of this was said in confused humor that was honestly impressive, given the circumstances.

Ever the guy for bluntness, Shouto shrugged. "Well it would seem someone has lied to you. Otherwise you wouldn't have reacted to my drink that way nor would we be here right now." He turned to gesture with one hand to the colorful void and the moving shadow. "For whatever reason, your spider demon blood had remained completely dormant and probably would have your whole human life if you hadn't ingested any magic born essence."

"Essence?" Hanta, though still confused, looked like he was keeping up with the information though still obviously processing. Perhaps he would have denied it more if the proof of Shouto's words weren't literally all around them.

Blue/grey eyes locked back onto black. "Specifically, my cum. You drank an omega prime's cum and it triggered not only your demon blood to surface but your very first rut."

The black haired man's face turned many shades of red before he practically glowed. "You! You-you….your CUM?" Hanta's thoughts raced. Should he be mad about this? Shouldn't he be? Yeah the drink tasted like a gift from God but holy shit that's...ok maybe that's actually kind of hot...fucking hell. And demon blood? Him? Mr. Average Joe? None of it made any sense but he's never been one to deny facts that are literally before his eyes. Yeah, it was against all logic but…

He closed his eyes, took a deep breath, and opened them with a slightly strained smile. "Ok. So that happened and now I'm a demon. What happens next?"

The look of surprise on the usually unfazed face of the other made his strained smile turn more real and wide.

Shouto was expecting a lot more reaction from the other. Denial, anger, panic, some sort of dramatic 'I can not believe!' schtick but Hanta seemed to just...accept this as it is. Honestly he appreciated that. Makes things a lot easier for them both. "Well technically you're apparently half demon, half human. The usual process for any half breed is when they first present, as in their second selves make themselves known, it triggers a type of breeding reflex. Heat, rut, or just extreme levels of horny all depending on the bloodline and second gender. Are you familiar with any of that?"

Hanta leveled him with a deadpan look. "Two of my closest friends are sex demons. I know waaaaaay more than I ever wanted to know about all that."

The two stared at one another a moment before Hanta snorted with laughter and Shouto shared his amusement with a slight smile.

"Well...true...then I'll skip the basics." Taking a step back, he opened his arms wide and gestured around. "During the first rut, your two sides often will come together to either align or dominate the other depending on the mix. As a human, your demon's side easily overwhelmed you and brought you here to more or less absorb you but as I have interfered, I'm able to help you align with your other half instead...if you want my help, that is?"

Eyes wide and skin pale, Hanta nodded rapidly. "Yes, please! I'd really prefer to not be absorbed so help away!"

Stepping closer, Shouto leaned in very close, his eyes scanning the other with a serious stare. "You will have to trust me completely with your very life. No matter what we do, you must let me guide you through this and follow my instructions exactly as I tell you. Can you do that?"

Did he really have a choice? Not really but...it was nice he was asked...and really, he didn't have a reason not to trust him. Who better to guide him than a half blood as well? Especially one that seemed to be powerful enough to keep his other half at bay. So...he nodded. "I can do that. Tell me what to do and I'll do it...though…" He tugged his bound arms a bit. "I may not be able to do much like this…"

A slowly growing smile spread across the other's face that knocked the wind out of him. It wasn't fair how beautiful he was. It really wasn't.

"Thank you, Hanta. I'm honored by your trust and will do everything I can to help you." A sweet scent surrounded them that made both Hanta and the shadows hum. "I will be truthful, I feel an attraction towards you, Hanta. Granted I would have preferred to try all this in a different setting but I will not lie and say I'm not feeling...excited."

Of all the things said thus far, that was probably the most unbelievable. Maybe he had died. Maybe this was his heaven? Or hell?

As he felt the other's hand touch his chest and travel down to cup his surprisingly rock hard cock, his mind blanked a moment, and his hips lurched forward with a hiss…before he turned bright red and looked down in shock. "How long have I been naked? Holy fuck have I been bare assed and hard this whole time?" The colors around them started to move quickly again in agitation.

"Easy…" the dual haired man whispered, his hand still resting on the cock. "Take a deep breath and try not to think about that. Focus instead on how you feel. Let go of all other thoughts and let the pleasure take you both." Slowly the hand started to wrap around a pump.

Though he wanted to say it was easier said than done, Hanta couldn't deny how it definitely felt amazing. He felt so exposed but it actually felt good to be. He was more sensitive. More open. And with his arms and legs bound, he felt...submissive.

Though part of him wanted to watch, the sight of his crush doing this to him was just too embarrassing for him so he closed his eyes and tried to let himself just enjoy it. Such a soft hand. Long fingers working him over with almost expert precision. Slowly he felt himself start to moan, his hips rocking into the touch automatically as he also heard the distant clicking turn to rumbling purrs.

"That's it, Hanta. Relax yourself into my touch. Feel your body rock and shift in pleasure, the heat of arousal grow inside…" The sight of the black haired man completely melting into his hand was affecting Shouto rather intensely. Smelling his own aroused scent from outside in this place was completely unexpected but it certainly helped make this process easier. After all, the demon was rut brained so what better way to align two sides than by making the human rut brained as well? The fact the aroused scent of the alpha demon was starting to affect him as well was less of a surprise, considering his initial attraction to the guy however the way his other self was trying to take the lead was highly unusual.

This was going to be a very unique experience for them both.

He shifted himself a bit to properly use both hands, the mixed temperature an extra thrill of pleasure to his Alpha- he paused only a moment in surprise before quickly resuming his actions. 'His' alpha? His other self had never claimed such a thing on any partner prior. Was it just the situation or…?

Hanta's moaning voice started to click and trill, the shadows swirling and slipping into his body as the two finally began to merge...and grow.

Very slowly, Shouto pulled himself out of Hanta's spirit and back to the real world before working quickly to remove the other's pants and resume his massage to the newly freed cock.

The glowing tendrils of energy slowly started to wrap around Hanta's body, completely phasing through Shouto as they covered the human body in a strange type of energy cocoon until suddenly his eyes shot open wide. Waves of black energy poured out of them, filling the inside of the cocoon with it, forcing Shouto to release him and back up.

The energy cocoon lifted high up into the air before growing and shifting until a bright burst of light filled the room, causing Shoto to shield his eyes.

Then the floor shook with a loud thud.

There in the middle of the room now stood a very, very tall Spidertaur. Black, sleek, powerful, with six onyx black eyes, golden yellow circles on his elbows, a white waving stripe across where the humanoid body met arachnid, and white bands around his upper arms, he was… "Beautiful…" Truly, Shouto was in awe...and absolutely soaked in arousal...but he needed to check that things went well. He must keep control here. So with a quick clearing of his throat, he called out. "Hanta? Can you speak?"

There were only rapid clicks and hisses at first until finally the spider demon lifted his hands to touch his face and body. "Wh...what..sssskah..am I?" He looked like he was struggling with his new mouth but the fact he answered at all sent a massive wave of relief though the other.

The first stage was done.

"You are in your true demon form, a very handsome spidertaur. You will feel slightly disoriented from the changes but don't worry, you'll be back in your human form once the rut is over. For now, we still have much to do." He walked over and reached a hand up to take hold of the now ridged and smooth textured cock that was steadily dripping pre down onto the floor.

The touch sent the spider body into a full shudder that nearly made all eight legs collapse. "I'm sure your instincts are already telling you what you need. Listen to your other self. What does he say?"

Once again it takes time for the words to form but this time the voice is full of power. "Mate. Breed. Claim." The shining black eyes zero in completely on Shouto before he's snatched up, lifted to eye level, and sniffed deeply. "Mmm...aroused Omega...mine"

Every word spoken in Alpha voice made the inner omega keen in pleasure. The strength, the scent, the desire, all absolutely delicious...and damn well difficult to contain. "Hanta. I know you can hear me. Don't fight your instincts but try to control them. YOU are the alpha."

Hanta hears him.

He hears and understands.

But everything feels like he's moving underwater.

The power and energy racing through his system like a drug feels amazing but the second voice in his mind is giving him a headache. 

Like, shit dude, maybe relax a bit?

Mate! Breed!

Look, we can't do that without permission, ya know? That's wrong!

Our Omega aroused! Mate!

Aroused isn't consent, dude. We are going to ASK first. IF he says yes, then we'll mate or whatever but if he says NO, then we back off, ok?

Mate!

DO YOU WANT TO HURT HIM?

No.

DO YOU WANT THE OMEGA UPSET?

...no.

THEN GET CONSENT FIRST, OK?

………….ok. Then breed.

If he says yes.

For the first time, he felt in full control.

The need was absolutely there, as was his new soul neighbor or whatever, but he was able to move without feeling like he was fighting to do so.

"Hanta?"

His eyes landed on the man still held in his hand and he smiled at him. "I'm here. Just had a very...interesting conversation with...myself? And uh...considering the situation I really need to ask, are you actually ok with this? I mean, I remember you saying you're...attracted but that isn't a reason to just have sex, right? I mean, if you're cool with, I'm absolutely down for it but if you're not, that's cool too just say the word and I'll back off completely even if I have to strangle hold myself-"

He was rambling and absolutely could not help it. This was not how he had ever dreamed his day, let alone his life, would go. The only plan of the day was to not look like a total buffoon in front of the sexy cafe cashier and now he was a demon and trying to ask him if he would like to have massive sex with him. What even is his life anymore?

Blessedly, he was cut off. "Hanta." The voice held a hint of amusement and it immediately made him relax. "I am absolutely consenting to having sex with you as long as we lay out some rules."

The enthusiastic nodding of a giant spidertaur shouldn't have looked as cute as it did but Hanta's eagerness to please bled through his power and was making Shouto's blood thicken with desire.

"No permanent mating bites. That means no biting here." He gestured to the glands on his neck. "You may lick and suck there but not bite. We'll talk that through when this is over."

The Black eyes flashed a moment before he nodded. "Other me is upset but we agreed it should be discussed later."

"Good Alpha." Shouto grinned seeing Hanta's eyes roll back with a quiver and waited for his focus to return on him. "You do as I say. I am a Prime. Your Alpha voice won't work in ordering me around so don't even try. If there's something you're uncomfortable with doing, just speak up and I'll adjust the order but NO ordering me." He reached a hand out to grab a handful of long back hair and yanked Hanta's face close. " I am in charge in this nest."

This time the legs all folded in as the spider demon's body convulsed with the shock of pleasure that shot through him. He's powerful, huge, and the ALPHA but...holy crap does the thought of submitting to this beautiful Prime make his cock throb.

What surprised all of them was his answer of "Yes, Omega."

Apparently his other half was into it too.

Sweet!

All thought left the second he felt lips on his own in a deep kiss before Shouto pulled back. "Set me down, Alpha."

The next while was spent setting up a proper nest with Hanta sitting to the side obediently with his hands tied behind his back with some of his own web silk. The whole room was getting thick with the smell of their mixed arousal as Shouto pumped it out towards him to watch his shiny black and dripping cock throb.

Oh yes, this big boy was going to satisfy every deep craving he had ever felt and then some.

Once the nest was ready he turned and pointed beside him. "Lay here, Alpha."

Mouth open and slightly panting already, Hanta crawled over and lowered his body as low to the ground as he comfortably could. The scent and need of it all had finally shifted his mind to full rut. He needed to mate. Needed it more than air. And finally his omega would let him.

The knowledge that he didn't even need to command his alpha to watch him as he undressed was an immediate rush to Shouto's system. He liked the attention. He liked the power he held over him. Every piece of clothing off his body had those black eyes drinking him in with crooning clicks. He knew Hanta was so deep in desire that he couldn't control those sounds and it made his inner self wiggle with delight.

Nothing was a more potent aphrodisiac than knowing someone you want wants you desperately.

Fully naked, he approached his alpha and ran his hands up and down the black toned chest, each slide down getting closer and closer to the absolutely swollen cock. "Such a big strong Alpha being a good boy just for me. Going to fill me up all full over and over again, make my stomach nice and round…"

The whole time the Alpha just nodded dumbly, his crooning clicks turning more like moaning till his hands finally took a hold of the dick that had needed both hands to fully encircle. "Omegaaa...Shoutooo...please…"

Normally he would tell the alpha to hush and not to speak till given permission but this was already overwhelming for the new demon so he let it go...this time. "Shh, I've got you, Hanta." His hands went to work, stroking, teasing, and lifting the cock till a particularly large glob of pre pearled on the tip.

He couldn't help himself.

The deep moan above him vibrated the room as he wrapped his lips around the pointed head of the cock and sucked, licking and drinking the thick liquid down till he felt the tip flex against his tongue. "Someone's already close...you're not going to waste this cum are you? Don't you want to wait till you're balls deep inside me?" His words were directed up but his eyes stayed locked on the expanding and contracting hole on the cock tip, waiting to see what would happen. He could tell Hanta was on the edge and could very well not be able to stop himself at this point but with a long hiss, the alpha managed to hold himself back.

"I...want it...please...let me...inside you...oh fuck...please please please…"

Oh no. How is he supposed to hold himself back if his Alpha was already begging like that?

Hanta's head lowered to catch Shouto's gaze with pleading eyes. "Use me, Omega Prime. Ride this Alpha till both you and your other self are full and satisfied. Let me be your good boy, please!"

The next moment was a bit of a blur for Shouto as he felt something inside him flood his system and the next thing he knew he was on the floor presenting with his ass held high in the air and waiting.

He heard his alpha stop breathing…but didn't move.

He was waiting for permission and it made Shouto purr. "Goooood Alpha...push inside Omega now."

With zero hesitation, Hanta used his front spindle legs to pull the Omega back to meet his thrust forward, splitting his hole wide open in one solid motion till he bottomed out.

The stretch burned sooooo good that Shouto couldn't contain his own whimpered moan at the sudden fullness. Oh fuck how long had it been since he felt this good? He couldn't remember. He felt every ridge, line, and vein against his clenching inner walls and was so lost in the feeling of it all that it took him several minutes to realize Hanta had stopped once he was fully inside and was panting heavily above him. Why did he...OH!

FUCK his alpha was too Perfect!

"Fuck me, Alpha. Fuck me now."

Instantly the motion resumed.

At a rapid pace.

It was absolutely wrecking his insides. He could feel it moving when he placed his hand on his stomach, he could see the bulge when he looked, and the knowledge unlocked a shattering orgasm.

His eyes rolled back, a scream of pleasure echoed around the room, and he squirted a large amount of slick along with a spray of cum out his dick.

Still the Alpha fucked into him and he heard himself start to beg. He didn't know what he was begging for but still he pleaded, whimpered, and sobbed as his body was thrown into another climax.

Large hands grabbed around his waist and lifted him into the air, his body flopped like a doll as the motion triggered his third orgasm.

So good, so good, so DAMN GOOD

It wasn't till his near tenth orgasm that he heard Hanta's voice in his ear, "please please please please let me cum, Omega, please oh fuck please I cant please need I need to cum Shouto please please" as lips kissed and drooled all over his neck.

Well that's a first. He was so blissed out he forgot.

With a biggest breath he could take, he commanded,

"CUM, ALPHA."

The grip around his body would have crushed him if not for his dragon density and strength. The roar above him rang as he was slammed down one more time and filled with so much cum it almost came out his mouth.

His stomach swelled to the max, teeth scraped his shoulder but didn't bite, and he somehow came again...

And blacked out.

 

Coming too was a very slow process.

He was floating, full, purring, and being licked clean by a deliciously long tongue. Oh he was so sensitive all over and it made no sense! How was he the one that felt so wrecked when it was his Alpha that was the one being controlled?

Another long lick and he moaned, eyes opening to see her was on Hanta's stomach high up in a web hammock with a dripping cock in his face.

What a delightful way to stay up!

Right as he felt the tongue slide back inside him, he immediately stuck out his own long tongue to wrap around the cock and bring it closer for him to suck.

The response was enthusiastic and though the licking was originally to clean, they both were quickly a mess once again before they napped together.

 

The week passed in a haze of kinky sex, small moments of food and water, sleep, and feral sex until finally Shouto was woken up by a high pitched chime.

The runes sensed the rut had ended.

He slowly turned his body to snuggle with his alpha a little longer and was surprised to feel normal skin. The soft warmth as pleasant and welcome as the fuzzy scales.

Sadly, the peace has to end sometime. 

"Shouto?"

Didn't mean he had to open his eyes though. "Hmm?"

"I'm human again."

"Mhm."

"Does that mean...it's over?"

"Mhm."

"Oh…"

It was the tone mixed with the sudden scent of sadness that had him opening his eyes and sitting up. "What's wrong?"

Hanta's eyes stared up at the ceiling. "Nothing just...nothing…" His black eyes closed hard for a moment before he took a deep breath, sat up, opened them, and smiled at the other. "Thank you for your help. I'm sorry to have caused so much trouble. I'll be sure to ask my parents about this since I'm sure there's going to be some changes in my life from this but I'll make sure to get a handle on this. I also apologize for more or less kidnapping you into this. I hope no one gets upset at you for being missing but if they do, just blame me."

One of the more difficult things to adjust to when you first present is how to control your scent. Hanta was smiling and trying to show his usual relaxed demeanor but...the scent of deep sadness and pain was so thick Shouto almost choked on it. Why? Why was he so upset? Was being part demon really so bad?

His other self started to whine inside in distress.

"Hanta? Are you-"

"Oh, sure! Don't worry about it! I'm sure there's lots of important stuff waiting for you so you go ahead while I clean up here. If there's a bill, I'll make sure to pay it before I leave, just let me know and...I completely understand if you'd rather I didn't come back…"

Shouto was very confused. "Hanta, I-"

"No really! I've got it! I-"

"ALPHA."

Finally Hanta's mouth slammed shut.

"I frankly don't care about any of that. I have a very capable staff that can run things when I'm not there and I've been due to take a heat break anyway so this actually helped me out quite a bit. Accidents happen, you're not the first to have triggered a rut or heat after a drink, that's why these rooms exist. It's a complimentary service we provide should it happen. You are the first to share such a thing with me but I'm not at all complaining.

Like I said at the beginning, I'm attracted to you. Even more so now after having your demon dick but I'd like the chance to know the person a bit more before asking to try the human dick next. That all depends on you, of course, but, to quote you, 'if you're cool with it, I'm absolutely down.'"

Pure shock would best describe the look on Hanta's face in that moment and it would have been hilarious if the situation wasn't so serious.

Slowly the scent changed to something lighter, happier, and Shouto mentally sighed in relief.

"I...I...I am absolutely cool with it, totally down, um absolutely, completely, yes, uh, please!" 

The previous smiles were nothing compared to the one absolutely beaming at him in that moment. "Good. For now, I am going to cuddle with you while there's still time to do so and afterwards we will work out the wheres and whens for our date before I walk you home to chat with your parents with you. I'm sure there will be questions and having someone with you to answer them might be beneficial as long as you don't mind me meeting your parents so soon. I'm not the most socially aware but the manga I've read has often indicated meeting the family doesn't happen till at least five successful dates…"

Hanta sat there listening to Shouto ramble on and on, every shared detail another reason to fall more for this guy and he couldn't believe the most beautiful man on this planet actually wanted to date him.

"-and of course I don't know your plans for the future yet but we'll get the details figured eventually, no rushing these things, I know, still-Mhf!!"

The surprise kiss caught Shouto off guard but he quickly reciprocated, happily and with enthusiasm.

 

Denki and Mina never let him let him live any of this down and proclaimed themselves the godparents of any future children as they insist it was because of them that the new lovers met and banged like rabbits.
