Work Text:
Izuku exhaled nervously as he looked around the darkened clearing. The pitch black of the area was offset by the soft glow of the flickering candles. The tiny flames danced about creating shadows that gave off an almost ominous ambiance. The greenette shivered in the cool night air even though it was summer. It was the night of the summer solstice to be precise. Typically a night of celebration, but for Izuku Midoriya…it was a night of opportunity.
See, Izuku is a witch that happens to attend one of the most prestigious schools of magic, Yuuei. There also happens to be a celebration on the solstices, which everyone usually attends, which means Izuku can be here without anyone else seeing him. Which was good. The thing was…Izuku wasn’t the most….talented…of witches. In fact you could say he’s a bit of a disaster.
It is not that he doesn’t understand the course work. No, he completely understands it and is quite intelligent. He has made theory his bitch, okay and he's number one ranked for the academic part of the schooling. Izuku’s problem stems from practical work. From his own magic…so to speak. It’s not that he doesn’t have any…he does and from scale tests he has more than anyone (student and teacher combined) on campus. It's just that anytime he tries to actually use his magic things go…wonky. Well, more like batshit insane.
Once he tried to charm a Tiger Lily to purr like a kitten and somehow ended up changing the flower into a carnivorous part feline part floral beast. It was terrifying and caused a lot of trouble. Another time, he was trying to conjure a simple rain cloud and ended up almost destroying the school with the hurricane he created….in essence he either got something totally different or an exuberant version of what he was trying to actually accomplish and most times…it ended up in troublesome borderline dangerous situations. Then he ended up the school's laughing stock.
Which is why when it came time for familiars to be summoned he wanted complete solitude to do his own summoning. It wasn’t expressly forbidden to do the familiar summoning on your own, but the teachers heavily pressed students to either have a person of staff or a senior student to be with them when they attempted the ritual. But well, the ritual was designed in a way that whatever was summoned couldn't harm the caster and if they did so they would be banished immediately so….Izuku figured his magic couldn’t override the ritual circle the principle himself created for it.
Besides, Kaachan did it by himself and he got a whole freaking dragon. Though it was strange how Kaachan blushed when his familiar got close and clingy. Kirishima had always been extremely friendly with everyone though, which was so at odds with Katsuki's attitude. It was funny that everyone besides Izuku (growing up with the hot head and with their slowly resolving history he's not cowed by his childhood friend…not any more, he was finally getting some friends and could stand by the blond as his equal despite his shitty control over his own abilities) was more scared to approach the blond witch instead of the dragon. That's besides the point…..
Izuku sighed at his addled thoughts. He was stalling the greenette knew. Mind still undecided to go through with this plan…his friends from class wouldn't miss him, believing himself to have fallen sick, while the rest of the school would be glad to not have the Witch of Pandemonium gracing their presence. Oh he may have gained friends and repaired strained relationships but that didn’t mean the bullying stopped. Though the teachers, especially his mentor, interfered as much as possible, it was impossible to catch all the bullying, more so when the majority of the school was doing so.
Again his thoughts were straying….he'd have plenty of time to do his summons alone in solitude…which is what he wanted. Finding his resolve Midoriya picked up the basket that held his offering. Each witch had to come up with a personal offering that would symbolize their oath…their bond. It would be something they were willing to give up to sacrifice for them in return for their devoted companionship and guidance. Izuku also wanted his offerings to represent something as well, to show what kind of relationship he was giving his familiar. Too many times has Izuku seen people trick their familiars in what is little more than a slavery contract by not imbuing their offerings with their magic, but by coating the items in a light layer of their magical essence to give a false pretense of sharing magic. Izuku wanted no part of that sick bit of trickery.
The greenette remembers the stories his mother used to tell him of how sacred the bond between witch and familiar was. He's never met his mom's familiar, he suspected it was why her and Auntie Mitsuki left their coven, but he always enjoyed hearing the stories of her summoned. It disgusted him when he saw how some of his classmates look down on familiars and though he can't interfere, he tries his best to help put the other summons with healing ointments and bandages. The only subject he was good at in practice was potions so he always used his allowance money to buy ingredients to make the ointments and healing potions himself.
Witnessing the awful treatment of this special bond had Izuku thinking long and hard about what to use as his offerings. He thought about what he wanted to give his familiar and chose carefully. What Izuku was offering was more than most witches would ever give as a tribute. Izuku remembered only one person in his grade giving something so vital as a sacrifice and that was Bakugou who also grew up with stories from Inko and his own mother.
Trying to keep his mind clear, Izuku walked over to one of the offering circles connected to the main magic circle. The emerald eyed witch began to chant as he walked…
"On this hour, hear my plea…
I call a creature of Magick to come to thee…
To pledge an oath of fates entwined…
Offered freely, body, soul, and mind…
My first tribute are items of home where care and support are of abundance…"
Izuku placed down two items in the first circle, which was a quilted patchwork blanket that had been on his mother's side in the family, where each child would add a patch once they reach the age of thirteen, as well as some homemade bread he and his mother worked on together. Once the items were put in the middle of the circle and glowed a deep copper red….huh it was supposed to glow silver. Midoriya didn't stop though, he lightly stepped to the second circle.
"For the second tribute I give that will declare my loyalty…
From the moment we bond my family is your family, my life is yours…
Should there be a time of great danger I would do whatever I can in my powers to help you even at the cost of myself…"
Izuku pulled out an ornate dagger, one he bought specifically for this ritual (it wouldn't do to use blood in any other ritual than this), and a silver goblet. Putting the goblet in the center of the second circle, the young witch unsheathed the dagger. Carefully, he cut across his wrist, letting the blood spill into the cup.
Once the goblet was filled about one inch from the bottom he hurriedly wiped the dagger clean on his cloak, sheathed it, put it back in the basket then pulled out a healing potion, and poured the content on his self-inflicted wound. During that time the goblet of blood glowed the same color as before. The freckled boy didn't even clean his arm as he walked over to the third circle. Feeling anticipation well within his stomach he reached in his basket for the last time and pulled out what looked to be a large chunk of some sort of crystal.
This was probably the toughest offering he had gotten. Not to mention he definitely knows he's the only one here that is even offering something like this. After all, most witches would be repulsed at giving a familiar their pure magic. See most witches imbue their tributes with their filtered magic power rather than an undiluted source of it. But Izuku had long since decided if he was going to do this he was going all in. With a little bit of help from his mentor who didn’t ask any questions, and a lot of exhausting pain filled nights, Izuku was able to pull out and condense his pure magical energy which is what formed this crystal.
"For my final offering, is one of Rights…
In standing, you shall be my equal in every way…
Through trials and tribulations, shall we prevail together…
In victory and triumph shall we revel our glory side by side…
This is my proposition…
Sic dictum, sic erit, nunc prodire qui me tenebitur…(So it has been said, so shall it be, now come forth the one who will agree to be bound to me)
Izuku felt the magic in the air swell as he yelled the last of the chant. Adrenaline buzzing, he took little notice of the sound of fireworks as he waited for the signs that the ritual had succeeded. In retrospect, the teen witch would be glad for those fireworks later on. He's not sure why he expected anything he ever tried to go normally, and what had actually happened would've had the attention of the whole campus if not for those fireworks.
There wasn't an instant extinguish of the candle flames, nor was there any silver smoke from the candles that met and condensed into the main circle matrix to form the familiar that chose to enter the bond. What happened instead, was an explosion….in an almost literal sense.
The candles flames erupted high in the air, higher than a hundred and eighty-two centimeters. The once orange color turned a creepy shade of magenta, and sparks shot out from the flames. In the middle of the magical matrix an eggplant colored smoke began to appear and expand. It didn’t come from the flames, nor did it float off like regular smoke…no it seemed to almost condense into a sort of fog that creeped low across the ground while the majority of it swelled at the focal point where it first appeared.
Midoriya realized by this point that his plan had gone, as he's used to, absolutely out of control. He should go get help…he should absolutely leave and get someone more experienced because whatever he managed to bring here was definitely not a creature of simple magical guidance. The young witch was stuck though, watching the proverbial train wreck as the mass of purple fog grow more and more.
Suddenly the fires from the candles went out…because the candles themselves were no longer there, just scorch marks were all that remained. The wind blew around the clearing, roughly jostling Izuku’s cloak before going absolutely still. No sounds were made. No other noises were heard beyond Midoriya’s heartbeat pounding in his own ears. Still, he could not tear his gaze from the fog.
The urge to blink was growing by the second, yet, the boy stayed frozen solid. Just as he was about to give in to the urge, is when something stared back. They were red and glowing, but what was even more terrifying was the fact that there wasn't just one set of eyes…there were two!
It was as the fog began to lift that Izuku’s eyes widened in a mix of shock and oh fuck. The…the creature was humanoid in shape, which was unheard of for familiars. Sure some could talk but they were always in the form of animals. That being said, the shape is the only thing human about it. Two huge spiraling midnight horns protruded from the side of its head that was framed with long inky black hair. Its mouth pulled back in a snarling smile that showed off wicked fangs that filled the orifice. The creature's skin was pale purple with darker purple markings that seemed almost runic tattooed all over.
Midoriya took in the large leathery wings and lazily tail flicking behind the being, but his attention was pulled in by how the skin faded into black scales at the elbows and knees where the hands and feet were adorned with claws almost like talons. As the young witch took in the creature it took him a minute for his horrific awe to die down for him to realize two things. Face set ablaze, Izuku noticed how…how tall and…muscled the entity was. Not only was it tall and muscled, but it was a hundred and seventy-eight centimeters of naked muscles and….holy shit!
Covering his emerald eyes with his hands he let out a quiet whimper as Izuku’s blush deepened. The thing was very…well endowed and nothing of its…package…was remotely human either. Why did that make his own dick twitch in interest?! He only moved his hands when he flinched as a husky chuckle filled the area.
"So you're the one that summoned me?" The dark voice murmured. It sent shivers down Izuku’s spine as he looked back up to those four crimson eyes.
Izuku couldn’t help the spew of words that had burst forth, "I…I am s-so sorry! I didn't mean to summon you…well I don't even know what you are but obviously not an animal, even a talking one! Way to go Izuku, you did it again, managed to screw up something that should be simple! What's the use of all this magic if I can't even use it properly!"
"What exactly were you trying to summon anyway?" The creature asked in an amused manner. It gave Izuku a sly smirk when he caught the greenette's gaze trying to glance down, which in turn distracted the witch when the being cocked his hip to the side and lent back slightly.
"I…I.." Midoriya shook his head to break his attention away from the…distraction…"I was trying to summon a familiar, but obviously the ritual for it went sideways as usual when I try to perform any kind of spell!" In a fit of defeat Izuku plopped down onto the ground, pulling his legs up to wrap his arms around them in a fetal position.
The teen witch was going to just wallow in his failure, contemplating what the school would say when it came out that he screwed up once again…but it seemed that whatever he brought forth wasn't going to let him. Though what the entity said did peak his curiosity.
"Well, no wonder…from this type of circle I'm guessing the majority of the witches here have light magic, your magic isn't compatible with these types of spells, rituals, or castings." The being….he really ought to get its name…said looking down at the circle matrix.
Izuku furrowed his brow, "What do you mean my magic isn't compatible and what is this about light magic?"
The creature stopped as it looked at the offerings then tilted his head to the side as he looked back at the witch in contemplation. Finally, as if he came to some sort of conclusion, he…definitely a he…gave a smirk, "You have no idea, none whatsoever about what you are? Hmm, how to explain this…" following Izuku’s example, the being sat down on the ground, but leaned back on an arm and spraying his right leg to the side while his other rested straight giving the freckled witch an…unhindered view of…well the entity's uncovered appendage.
Trying to keep from ogling at the damn thing, Izuku focused his sight on the creature's face. He seemed to know exactly what he was doing by the smug expression. "There is more than one type of magic. While there are many nuances and subtypes there are three main branches of magic that they all fall under. Light, Natural, and Dark. Now, full blooded humans have light magic…which explains why only light magic is taught here…but you, my little promised one, do not have any light magic at all. Which is why your attempts of the magic taught here would malfunction."
Confusion overriding the attraction Izuku felt, he spoke, "If I don't have light magic then what type do I have? And how do I have a different type of magic if humans have light? Why did the ritual summon you?"
"An inquisitive mind, that's an attractive trait in a promised one." The being purred which interrupted Izuku’s questions. He blushed furiously at the complement and stayed silent until the other began to speak again, "This type of ritual…for light magic users, they need the complexity of the matrix to call forth a guide. Their magic isn't dense enough nor in great amount to call forth a guide, so they use this to basically broadcast and amplify their own magic to do so. For dark and natural magic users though…if they need a familiar it doesn't need such a complex process, just simple meditation while releasing your magic will do the trick." Izuku made an excited hum at the information taking little notice when the being slowly leaned forward.
The entity continued on as he got on his hands and knees, he began to stalk ahead, "It is very rare to find a human with natural or dark magic, simply because that means the human in question isn't fully human at all. All humans that have a different type of magic besides light can find traces of non-human races in their ancestry. Depending on how much magic the witch has depends on how close the relation the creature in question is. For you…well you definitely have dark magic and I would say you're a first generation hybrid at that with how powerful your magic is. One of your parents had to have been non-human."
Izuku felt his jaw drop, "W-what…but…my mom…" but he paused…he knew nothing of his father. Anytime he asked his mother all she would talk about….would be her familiar…could it be? If his father wasn't human though and his mother was then how did she summon his dad? Was there a way light witches could summon other beings of different magic? More and more questions began to pop up, but those were put aside as the entity purred again.
Izuku’s eyes widened once more as he saw the creature had left the circle, something that should not be possible until a familial bond had been put in place. Before the young witch could say anything though the entity licked his lips making Izuku gulp. It was long and just like his markings a deep purple, though his saliva dripping off was a voracious toxic green color. "Hmmm, yes if not your mother then your father perhaps. It doesn't really matter though, for Dark and Natural magic users this type of ritual is used for only one thing. To bind together two souls, and from your tributes you're offering so much more." The entity was now in Izuku’s space who was trembling in a mix of emotions. Confusion, lust, anxiety, adrenaline, fear….anticipation…
Obviously his own dick figured to just do its own thing despite…or maybe because of…Midoriya’s emotions, as it stood erect. The tent in his slacks was in plain view to the creature's pleasure as it hissed, "Yes, your proposal was quite enticing. I'd have been a fool to turn down such an exquisite mate."
By this point he was in Izuku’s space, and had placed its clawed hands on the teen’s upper thighs while nuzzling his erection. Panting as his head swimmed as what little blood in his brain went straight to his dick, Izuku plopped down on his back. "I don't even know who you are….or what you are!" Was all the boy could think to say. No where in his mind did it occur to Izuku to deny the creature, to stop what was happening.
The greenette looked down and felt his breath catch at the hungry gaze of the creature. "I…" the entity paused to use it's claws to rip his slacks and underwear to shreds, baring Izuku’s twitching cock to the cool air, before continuing to hiss, "...am Aizawa Shouta, as well as the devil lord of the ninth level of hell. And you will be my mate and consort…" Then he extended his tongue.
Izuku watched as the appendage wrapped around his cock causing him to moan and tremble as it went straight to work. It pumped him. "O…oh….th..that….Sho…." Izuku tried to speak, but with the only experience he's ever had being his own hands, this was overriding his motor functions and all the witch could do was hang on for the ride. His hands gripped the newly dubbed Shouta's horns when the thin tip of the…holy shit a devil…devil's tongue probed at the slit of his penis where a good amount of precome had begun to bead up.
"Oh my god!" Izuku exclaimed in a gasp as the tongue did a little twisty motion. The chuckle of response from the devil had his hot breath wash over his member which amplified the sensation, and had his toes curling.
Izuku whimpered when the tongue moved off for Aizawa to speak, "There is no god here, little mate. If you must call out something then my name will suffice."
Izuku would have made a sassy comment. Really, he would have shown a bit more of that back bone he's grown, but just as he had something on the the tip of his tongue, his dick was encased in a wet, hot, suction. "S-shhooutaaaa!" Izuku squealed. He squirmed as the demon above him moved his hands to grip his hips and began moving him back and forth in his mouth. The greenette could feel the other’s drool and his own precome making a mess of his thighs and began dripping down passed his balls to his opening.
Within minutes Izuku could feel the lust in his gut tightening. He was almost there at the edge, just a little more and he'd orgasm. But just as he tensed up, just as he was about to fall over into bliss that…that damned tongue quickly wrapped around the base of his cock tightly. "N..no, no please, please let me come…please Shouta!" Izuku cried at the denial of his pleasure.
His body wracked with shivers, though it took a moment for his mind to clear enough to realize that the demon was petting his thighs to sooth him and that his mouth was no longer attached to his lower extremities. "Shh, Shh my little mate, it's okay. You'll get your release I promise, but I need your help with something."
"W…what…" Izuku panted out as he looked up at the four glowing eyes.
His gaze was diverted to Shouta’s hand as he gently used one to grab Izuku’s right hand and brought it down lower and lower until his fingers brushed against his own hole. "I can't open you with my claws, so I'll need you to stretch yourself for me. Can you do that for me, my little mate?" Izuku nodded his head in a daze as he began to rub and prod at his anus. He wondered if Aizawa was just going to watch him but that question was answered when the devil muttered, "What a good boy, I have another way to help though…"
At first, Midoriya was confused but that confusion was cleared up but a moment later when the horned head bent down and…oh that was definitely his tongue licking at his hole around his fingers.
"Sh…oooh…ah, ah…f..fuck…" Izuku felt drool slip down his chin as one of his fingers sunk in…hub typically it takes a bit more time for him to relax enough to fit a finger…maybe Shouta’s saliva had magical properties…his thoughts stopped when a clawed hand pushed his hand forward causing his finger to sink deeper inside himself. Hips humping down on the finger, Izuku earnestly began to pump his finger in and out. The witch's hole spasmed after a few thrusts when Aizawa began to also insert his tongue beside Izuku’s finger. What an euphoric sensation he was receiving. A pinch to his thigh reminded Izuku why he was fingering himself, before he could get too lost in pleasuring himself, and so he added another finger.
After a few pumps of his fingers, Izuku added a third finger but was surprised when Shouta shoved more of his tongue in forcefully. "Nnnnaaaaaahhhhhhh……"Izuku moaned when the slick appendage pressed on his prostate. The teen tried to move his hand but the tongue kept hitting his g-spot which had liquid fire race down his spine. Finally having enough of the teasing, Izuku removed his fingers to grab at the devil's horns and yank his head up. "Inside me, get inside me now Shouta!" Izuku demanded. His demand earned him a fanged Cheshire grin.
Shouta slithered up, and in a quick movement that made Izuku’s head spin, flipped the boy on his hands and knees. One clawed hand pushed his upper body to the ground causing his cloak and shirt to pool up at his shoulders, while the other had a tight grip on his hip. Izuku felt a little disappointed at not being able to face the demon, but was comforted when Aizawa's tail wrapped around his upper left thigh. Izuku felt his heart skip a beat when something hot and heavy rested against his loosened opening. The something that he had kept staring at since Shouta had been summoned. Oh…he was about to have a devil's cock take his virginity.
Izuku didn't feel an ounce of regret for it. Not one bit, because all he could feel was an intense pressure then sudden heavy fullness as his ass was penetrated. Izuku trembled as he could feel every ridge, and bump…the tiny barbs that lined the underside of Shouta’s cock sent particularly intense bolts of thrill through his nervous system. By the time Aizawa was fully seated inside Izuku, the teen swore he could feel the devil in his throat. Tilting his head down, the greenette moaned, "Ohhh…oh fuck Shouta…yo…your cock…"
Right there just underneath his belly button was a small bulge where Aizawa's dick was making room. Too big to even fit properly inside Izuku. It should hurt, Izuku shouldn't be feeling any type of pleasure, but pain was the furthest thing from Midoriya’s mind as his thoughts were muted with a rapturous haze.
After a moment's pause, Aizawa suddenly pulled back and began thrusting in rough and deep movements. Each movement rubbed that delicious cock over Izuku’s prostate making white light dance along his eyes. Chanting the demon's name nonstop, Izuku blindly reached a hand back to grip once more at the other's horn, needing something to hold onto as he was jolted forward from the harsh thrusts.
Emerald eyes rolled back when he felt a warm nose nuzzle the back of his neck, before that long tongue extended to wrap around his throat….like a claim…like a collar.
"Fuck…Shou…Shouta….so good….more…please…faster…need it faster." Izuku sobbed. He felt more than heard the inhumane snarl that Shouta released before his pace began to pick up. It shouldn't have been possible, his body shouldn't have been able to handle a fucking quite like this, especially with it being his first time, but Izuku knew that he'd never be able to have anything else but this from now on. He was getting addicted to the feeling. No normal human cock could ever please him like this.
He tried his best to rock back on the scorching member, but his legs were quivering so bad that he had to stop just so he wouldn't face plant into the ground. The tongue around his throat sensually unwrapped itself, licking up and around the shell of his ear as it pulled back, and it took him a few seconds to realize it was because Shouta was talking.
"...ats right, just take it. Just like that take my cock like you were meant to, my beautiful little mate. Just think we'll do this every single night, I'll pose as your familiar and all the while you're learning about your magic I'll have you seated on your rightful place on my cock. Would you like that, my little mate? Sitting on my dick while in class, I can cast an illusion. No one would know that you were getting railed by a demon such as me while in class…mmm…" and he just kept going and going.
Izuku could picture it too. Him bent over on his desk with his pants down at his ankles….or better yet, if he clipped his cloak closed he would even need to wear any pants. He could go bare ready and waiting for Shouta to take him whenever in class, while the rest of his classmates and teachers remained unawares.
"Yeeeeessssss…." Izuku hissed, "...want it….whatever, whenever….I'll give it to you…please just don't stop." Izuku felt the other's thrust falter then picked back up even faster
A guttural chuckle caressed his ears, "Oh, whatever and whenever…that's a dangerous promise my little mate…one I will be gladly taking advantage of…"
Izuku just cut him off by turning his head as far as he could and pulled the devil's head forward. They connected in a kiss as best they could in the position they were in. Izuku couldn’t take it anymore. He went hurtling over the edge, his orgasm ripping through his causing him to seize and spasm on the dick still pumping inside him. The tongue down his throat muffled his whines, and when he could no longer hold himself up he slumped forward.
Shouta continued to fuck into him, chasing his own pleasure as static filled Izuku’s brain. He still could feel jolts of sensations whenever his prostate was hit, but was too blissed out to move much. It was strange, he should be getting too oversensitized, but it was like as long as Aizawa wasn't finished his body stayed in a state of blissful pleasure.
Soon enough though, Shouta’s pumps faltered once more, becoming harsher as he grinded deeper and deeper before a roar sounded in the air. Then a sharp bite to the back of Izuku’s neck breaking skin had euphoria to rupture through him once more, and more intense than ever. It was like every fiber of his being was exploding then being reformed once again into something new…something….more, before his mind went blank.
Midoriya didn't notice when Aizawa pulled out after he came inside the witch. Nor did he twitch as semen began leak out. Izuku was on cloud nine, and not even when he was turned around on his back brought him out of that blissful haze.
He was exhausted though, as his body began to naturally shut down to get some rest he vaguely felt his legs being pulled wide and something large and heavy once more pushed inside him.
Just before he fell into unconsciousness he heard a heady purr whisper to him, "Just rest my beautiful little mate, this will be the first of many you'll sleep and wake with what's rightfully yours inside you. My lovely wonderful little witch."
