On July 15, Midoriya Izuku was born into the world, screaming bloody murder, covered in blood and fluid discharge, with wrinkly skin.

Just like all babies, basically.

Except, it wasn’t only Izuku who was screaming that day. Nurses almost dropped the baby in shock when the monitor didn’t detect a heartbeat. The doctor yelped and cradled their bleeding fingers after clearing out the liquid in the baby’s mouth.

Later on the staff sighed in relief when they found that the plug for the machines were loose, and that the doctors had nicked their fingers on a nearby scalpel.

Midoriya Inko didn’t bother telling them that neither she nor her husband had red eyes. She didn’t bother calling the nurse when the monitor went dead even as she held the warm, breathing body of her sleeping baby against her chest.

She was busy coddling the cutest child in the world after all.

💧🍷💧🍷💧🍷

A few months in, Izuku had to be put off breastfeeding and switched to drinking milk from baby bottles. At this, the nosy neighbors had gossiped behind Inko’s back, their words of disdain and clicking of tongues fashioned like knives.

Inko wasn’t blind to the disappointed stares that followed her when she did her weekly groceries. Nor was she deaf to the whispers which increased in volume when she walked past.

“And she calls herself a mother?”

She heard and saw them, but she didn’t care. After all, they had no business in knowing about the band-aids that littered her breast, and the minuscule scars on her nipples.

All she cared about was the bundle of sunshine that greeted her with a bubbly squeal of joy after a long day at work, when the babysitter would hand him off to her ready arms.

In this world of quirks and superpowers, she didn’t really bother to think twice over the unique qualities of her son. And even though the usual age for manifestation of quirks was at 4 years old and not minutes old, she shoved the nagging thoughts and doubts aside.

“Izuku, sweetie, I’m home!”

She smiled when bright emerald green eyes greeted her– the red eyes had lasted for a day at most and never showed again.

She doesn’t know what she did to be blessed with an angel.

💧🍷💧🍷💧🍷

“Mama? Why we leave?”

2-year old Izuku looked up at his mother with his big sparkling eyes, confusion and concern etched on his face.

It was a look he’d gotten used to having when it came to his mother. Well, specifically, when it came to his weird things.

Izuku knew he wasn’t like the other kids he met at the park and at school. Not in the way that he was awkward and shy, no.

He was smart.

When their teachers would give them the go-ahead to play with blocks or read some children books full of illustrations, Izuku found out that he was smart. Smart and fast.

Where others would struggle fitting squares into the proper-shaped holes, he would be by the corner, already drawing up architectural plans involving the childish blocks. Where they would giggle over illustrations, he would pore over the numerous kanji characters of literature books.

Of course, the fact that his mind was sharp and fast hadn’t passed over to his body yet. Which is why he still struggled with pronouncing words and names or drawing characters on paper even though he knew how.

But he observed as day-by-day, slowly but faster than most, his body was catching on quick. Just the other day, he’d managed to smoothly draw the characters for his name– in kanji.

To be honest though, there was another reason why Izuku knew he wasn’t like the other kids. It was the reason why he and his mother had gone to the hospital this morning, but promptly ran out right after.

He swallowed and winced both at his dry throat and at the scorching rays of the sun that seemed to make him more thirsty than usual.

That. That was why he wasn’t like the others.

Izuku was always so so thirsty.

He knew he told his mother that he began feeling the itch in his throat and the tingling of his teeth a few weeks ago, but that was a lie.

Since he came to know the word, Midoriya Izuku had been thirsty. And before that, well, the milk helped, that was for sure. Water too, had helped. Drinking especially cold water made the parched feeling dissipate for a while before it came back, rearing its ugly head.

As a smart kid, he thought he could get a handle on it– work out the kinks and find a solution without confiding in his mother or in his teachers.

He should’ve told her sooner.

Inko smiled down at her son, but it was too tight and forced, her eyes bordering on panic and fear. Once they were a good distance away from the hospital, she sat them both down on a shaded park bench.

She saw the relief in Izuku’s body when he got under the shade and couldn’t help but be reminded of the revelation the day gave her.

Though to be honest, she knew this was the nagging thought that had been poking through her mental walls of self-denial since she held the small body against her chest– one that didn’t have a heartbeat but gave her squeals of joy.

Looking around warily, she kneeled before Izuku, holding his hands to give reassurance– both for her son and herself.

“Izuku, my baby, I have something to tell you, okay?”

The greennette cocked his head to the side, obviously confused and budding with questions, but smiled and kept his mouth shut.

Inko took a shuddering breath, momentarily tightening her grip on small hands to stop her own from trembling. In and out, in and out, Inko.

Dark green eyes met with vibrant emerald ones.

“Sweetie, you know how you’ve been thirsty lately? How drinking water or milk doesn’t make the itchiness in your throat go away? And how–“ She hesitated, “When your classmate hurt their finger today and it bled, you couldn’t concentrate and they had you sent home?”

Izuku nodded vigorously, feet swinging back and forth on the bench. He was excited! He knew from the tone his mother was using that she knew something! In his excitement, he didn’t notice the tremors wracking her body and how her smile became wobbly, her eyes shining.

“Oh Izuku, my baby angel, you...” She squeezed his hands, “You’re something we call a vampire.”

He froze in his seat, his feet stopping its swinging.

“Vam–pire?” The word tasted foreign on his tongue, but saying it made something click in his mind– like the word had been one of the playing blocks missing to complete the grid. It was a word he had never encountered but something he knew was right.

“Oh!” Izuku smiled, feet swinging back and forth again, “Is that my quirk, mama? Was papa vampire too? Is that where I from? Oh, but I not 4 yet, mama! Am I an early, uh, planter? That’s what teacher called me when I made really tall tower–“

“No, no, baby, it’s–“ She swallowed, lips trembling, “It’s not your quirk, Izuku.”

His lips downturned, brows furrowing. “No?”

Inko shook her head, and Izuku couldn’t help but wonder why her eyes were so sad. He didn’t like it when his mother was sad.

“It’s just... something you are, Izuku. Sometimes,” She squeezed his hands, green meeting green, “There are people who are born as... something more. They come into the world and they just are, Izuku, like you are. Sometimes it’s because of their parents and sometimes–”

Inko pauses.

“Sometimes it’s completely by surprise.”

Izuku was still frowning, not completely understanding. Not due to lack of his own ability to comprehend, no. But because his mother was speaking in too vague terms that sounded like riddles and reminiscing.

He wants to hound her with the millions of questions that threatened to burst from his lips, but he decides to research on his own instead after noticing the tremble in her hands. For now, he needs to give his mother support!

Izuku jumped from his seat and tackled his mother with a hug, the latter quickly balancing them both on her knees. He looked up at her, a small smile on his face.

“I’m vampire, mama?”

He thinks he sees a sliver of fear cross her face, but it’s gone before he gets to process it. Inko cups her son’s face, cradling it between her hands.

“Yes, my angel, you are. But I need you to promise me, Izuku. Promise me you won’t tell anyone.”

He furrows his brows and pouts again. “Why not? Is bad to tell people what I am?”

She shakes her head, eyes looking soft and sad at her son. “No, sweetie, it’s not bad. It’s never bad to show people who you are.”

Inko planted a kiss on his forehead and Izuku giggled at the touch.

“You should never be ashamed of who you are, Izuku. But,” She moves to embrace him in her arms, whispering against his ear, “There are bad people in the world, my baby. Bad people who would do anything to take you away from me if they find out you’re a vampire.”

At the mention, his ears perk up and he whispers, “Bad? Villains, mama? Villains take me away?! No!”

“Shh, Izuku, it’s okay, baby,” She tightens her hold on her son, the light of her life.

“I won’t let them– I won’t let anyone take you away. And no one will, Izuku. As long as you promise me you won’t tell, okay?”

Izuku was conflicted at this point. He wanted to say no because the thought of hiding a vital part of himself felt wrong and constricting, like shackles on his hands and ankles. And he wants to be a hero! A hero doesn’t run away from villains!

But he feels the rain that comes from his mother when she was sad fall on his face and concedes.

Being a hero was important and cool, but his mother was crying and all he could do was nod and hug her tighter as he waited for the rain to stop.

💧🍷💧🍷💧🍷

When Izuku met Bakugou Katsuki, it was the first time he was hit with the reality of his nature– not quirk, he reminds himself.

When he peeks out from behind his mother’s skirt, his eyes lock with vibrant crimson ones and he’s captivated. He clutches at his chest because his heart uncomfortably thumped against his chest.

Then the blonde boy shifts and Izuku freezes.

Green eyes zoom in on the pulsing jugular vein, with occasional beads of sweat running down the small neck. There’s a rushing in his ears, his teeth tingles, and his mouth suddenly fills with a liquid that was way better than water or milk.

Immediately, he swallows and for the first time in his life, his throat wasn’t itchy. Izuku wasn’t sure how he knew it was his blood, but he sets that information aside for later to put in his notebooks. The fact that it was his blood made the itchiness go away, but did nothing to ease the parched feeling.

Izuku’s eyes go back to the boy’s neck and he feels the familiar tingling again. Expecting it, he opens his mouth slightly and runs his tongue across his upper teeth and– oh.

He had fangs!

“-zuku, Izuku! Come on now, sweetie. Introduce yourself! This is Bakugou Mitsuki, they just moved here!"

Inko pushed the shy greennette forward, gently prying his fingers from her skirt.

Still reeling from the revelation of his fangs (oh my god), Izuku didn't forget his manners and spluttered his greetings.

"H-Hello! I'm Midoriya Izuku! N-Nice to m-meet you Bakugou-san."

Mitsuki cooed at the adorableness of the boy, seeing similarities between the two Midoriyas. She gave him a wide smile and her fingers itched to pinch the adorable freckled cheeks that flushed red.

"Nice to meet you too, Izuku! You can just call me Mitsuki-san" She shoved the small blonde boy beside her forwards, "This is my son– oi, brat! Introduce yourself!"

"I don't gotta do shit, hag! Ow!"

"Sorry for him, I don't know where he got that potty mouth from."

"Where else would I get it but from you, ha?!"

Seeing the mother-son duo ready to have another bout, Izuku butted in. He shuffled over until he was standing in front of the blonde boy (whose jugular was still catching attention in the sunlight).

"U-um, h-hello! What's y-your name?"

Crimson eyes shining like jewels swiveled to his, finally acknowledging Izuku’s presence. He scowled and moved to tower over the greennette– which wasn’t admittedly much, but the uneven ground helped.

Izuku, on the other hand, was just trying to stop himself from making a scene with the drool that threatened to spill once he caught a whiff of something sweet and spicy from the blonde boy.

Personally, he couldn’t manage spicy things but this he would definitely like a taste of.

(He thinks he should be concerned about having such thoughts as a 3-year old, but he’s too busy containing his drool and fangs)

The blonde boy puffed his chest, “Bakugou Katsuki. You better remember that, you extra.”

Elated, Izuku tries out the name of his new friend– not meal not meal not meal.

“Kachki?” Oh, that sounded wrong. Frowning, Izuku tries again.

“Kacchiki?”

This is one of the moments where Izuku gets frustrated with the delay in growth his body had in relation to his mind. He knew how to pronounce the name– he even knew the various combinations and meanings from the possible characters!

But his body was still 3 years old and had the verbal capacity of one. Still, he tries again, not noticing the stewing blonde.

“Ka–Kacchan?” Oh, that was better. It was close, not quite right, but not wrong either. Plus–

“WHAT?! YOU SHIT, WHO YOU CALLIN’ KACCHAN?!”

–the blush coloring his new friend’s face down to his enticing neck was worth the mistake.

💧🍷💧🍷💧🍷

They were watching an All Might movie in Katsuki’s house the first time it happened.

Since their first meeting several months ago, Izuku had stuck himself to Katsuki’s side like an adorable puppy. Or, in the blonde’s words: like an annoying blood-sucking leech that won’t take a fucking hint.

The greennette had to beat the juice he choked on from his chest when the comment hit too close to the truth.

Well, not exactly the truth. His eyes strayed from the bright screen to his best friend– particularly, his neck. He gulped when he felt the all-too familiar tingling of his teeth and tightening of his throat.

Izuku hasn’t really, truly, sucked blood yet.

When they came home after having dinner with the Bakugous, he wasted no time in telling his mother about the new revelation. Like with all things related to his.. nature, she went pale with shock before snapping herself out of it.

That week, Inko garnered a lot of weird stares when she left butcher shops carrying bags filled with questionable liquid. When neighbors dared to approach and subtly ask about them, she just gave them a polite smile.

“I heard of a new recipe, so I wanted to try it out!”

And that was that.

If the garbage collector paused when he saw the Midoriya’s bag for recyclables full of empty plastic packets with leftover black-red liquid, he didn’t mull over it. He’s seen worse things in his line of work, after all.

So Izuku hasn’t really, not truly, sucked blood yet. Even when his mother tried making him drink from a pet bunny, he refused for fear of killing it.

Blood packets were controlled, and well, not alive. Compared to the warm and refreshing taste of his own blood, it tasted similar to the stale bread bakers would give him on the way home. It quenched his thirst, yes, with his throat no longer parched for the first time in his life.

“Ha! Did you see that, Deku? The stupid villain actually thought he could sneak up on All Might! Idiot!”

But the thirst always, always came back in full force– like it never went away– when he was with Katsuki.

Like now.

Izuku gulped, tongue absentmindedly going across his lengthening fangs.

Especially when they were alone.

Oh no. This was a bad idea.

Katsuki was still enraptured by the movie playing on the big screen, hands on the floor as he leaned forward on his folded legs. His usual scowl was replaced by a wide grin, his crimson eyes shining with admiration as they followed the characters battling.

Izuku knew he should also be watching the movie. After all, he was the one who picked it after badgering his friend to let him have a pick for their movie night.

He should, he really really should. It would be easy to pull his eyes away from the pulsing jugular vein that seemed to beat as if enticing him.

Bite me. Bite me. Bite me.

He had better self control than most kids his age, after all. Heck, he managed to potty train himself faster than others by a wide margin. And he didn’t give in to the temptation to steal the candy their teacher left on their table! So Izuku prided himself in self-control.

A bead of sweat rolled down Katsuki’s neck. The greennette gulped, mouth hanging slightly open, a hint of his fangs glistening with drool showing.

His rational mind was about to snap him out of it when the AC blew their way, sending a whiff of Katsuki’s unique scent of sugar and spice straight into his nostrils.

Oh dear.

Maybe it was a spur of the moment, Izuku thinks later on. Maybe it was the fact that his mother had trouble getting this week’s worth of blood packets. Maybe it was because they were alone with no adult watching over their shoulders.

Or really, and this is the most likely explanation, maybe it was because it was Kacchan.

Izuku pounced, fangs ready to sink into the tantalizing neck that looked juicier than any katsudon he ever ate.

The greennette was so drunk on the idea that he pounced mindlessly, not noticing his mea– no, friend, friend, friend shifting and turning towards him, crimson eyes widening.

When his mouth met flesh, he bit down.

“WHAT THE FUCK, SHITTY DEKU?!”

Izuku was aware of the hand pushing at his shoulder but the high of the exquisite sweet, sweet blood filling his mouth filled him with unnatural strength. He grasped Katsuki’s wrists away from him, and sucked.

“Wh– Shit– Fuck, D-Deku, you–!”

It was only when Katsuki’s hands and body went slack that Izuku snapped out of it. Horror and dread filled him when he abruptly pulled away, a trail of blood and saliva following him.

Katsuki was leaning against the couch, chest heaving, his crimson eyes hazy and disoriented. There was slight bruising around his wrists, but the worst sight was where Izuku bit him. His shoulder had two punctures where blood was still flowing down, some bruising already showing around the bite.

Izuku didn’t know if he was even allowed to feel disappointed that he missed his best friend's neck.

“K-Kacchan! Oh my god, are you okay?! Oh no, no, no, what did I do? Oh god I wasn’t thinking and now Kacchan’s going to die! Kacchaaaan don’t dieee–“

A pillow hit him in the face.

Flubbing, Izuku rubbed at his nose.

“Christ, I ain’t gonna die, idiot,” Katsuki huffed and glared, but failed with his eyes still hazy and breath still coming hard. The blonde winced when he tried moving his shoulder.

At the action, green eyes focused on the still flowing blood. He licked his lips, almost shuddering at the remaining sweet taste.

Izuku shuffled closer to Katsuki, who glared at him but couldn’t muster the energy to snap at him. With careful hands, he held the blonde’s hands and lifted the bloody arm.

Bright emerald green eyes met crimson red.

“Kacchan, it’s okay, I’ll take care of everything,” His voice sounded surreal, a sort of hypnotic undertone coloring it. Katsuki looked to resist it before his body went lax, eyes fluttering close, his breathing slowing.

Izuku strangely felt a warm feeling in his chest at the show of obedience, but tucked that observation for later.

Now, he had important matters to focus on.

With an almost reverent touch, he lifted Katsuki’s hand– now dripping with blood– and began licking every drop. From his fingers to his wrist and all the way up to the punctures on his shoulder.

Even as his fangs tingled to take another bite of his meal– friend, Izuku wrangled control and opted to lick every drop of Katsuki’s blood until the wounds closed (another thing he needs to jot down for later).

With one last lick, he finally let go and looked up at Katsuki. There was color flooding back in his face and his eyes were no longer in a haze, crimson glaring at the greennette.

Izuku scrambled back, apologies (and maybe bribes) ready to spill.

But all Katsuki did was huff and pinch Izuku’s cheeks really hard before turning back to the movie, hands grabbing for the remote.

The greennette was confused by the reaction but decides not to look a gift horse in the mouth, reluctantly returning to the movie.

Izuku swears he hears Katsuki mutter fuckin weirdo Deku before he’s swept in by All Might’s Detroit Smash on the screen.

💧🍷💧🍷💧🍷

It happens again on Katsuki’s 4th birthday and this time Izuku had permission.

“Uh, wuh?”

In Izuku’s defense, when Katsuki dragged him to his room after the party, he was expecting his friend to show him the new All Might figurine. Or the new poster, maybe.

Definitely not being asked flat-out if Izuku was planning to have another taste of the forbidden fruit (yes, he now dubbed his best friend as that).

Forbidden because when he came down from the high of drinking for the first time, all possible scenarios of what could have gone wrong plagued him for days.

And fruit because, well, no matter how many times Izuku brushed his teeth and drank other blood packets, the saccharine taste of Katsuki’s blood remained on his tongue.

“Oi, shitty Deku! You ignoring me, ha?” Katsuki growled, his palms sparking and crackling.

There was also that development. His best friend got his quirk! It was flashy and cool, and Izuku couldn’t wait to get his!

“Um, er, no, Kacchan! I was just, uh, what?”

Katsuki clicked his tongue and flopped down on his bed, which Izuku noted was covered in a limited-edition Silver Age All Might bedsheet.

“You got over it or somethin?”

“Got... over?”

Katsuki scowled. “Your weird biting thing, Deku! Oi! Don’t tell me you forgot when you almost mauled me!”

“M-mauled..! K-Kacchan! That’s not–“

“Yeah, yeah, whatever. So you got over it, huh.”

If Izuku wasn’t drowning in embarrassment (and maybe guilt) over the reminder of what happened the last time, he might’ve noticed the disappointment in Katsuki’s voice or the slump in his shoulders.

What he did notice was the thrum of excitement crawling under his skin, perpetuated by the tingling of his fangs.

”Ugh, let’s go the fuck back down then, Deku. There’s probably still some ice cream left,” Katsuki huffed and moved to leave the room.

It might’ve been desperation, Izuku thinks. Might’ve been some leftover jealous feelings from when their other classmates swarmed Katsuki with gifts.

He wasn’t entirely sure of the reason why, but he moved– incredibly fast– and blocked Katsuki’s path to the door.

"What the fu–"

"I can? Kacchan?" Izuku grasped Katsuki's wrist, with a firm but gentle hold. "I can bite you again?"

The blonde shivered at the sight of eerily glowing emerald green eyes, but couldn't look away. The look was expectant, predatory, but patient all the same.

Katsuki gulps and green eyes follow the movement.

"Yeah."

Izuku smiled and before Katsuki could process why seeing it made his chest and face feel warm, the greennette went in for the kill.

Instead of his neck or his shoulder, Izuku turned his best friend's wrist over, eyes greedily devouring the sight of stark blue-green veins on pale skin. He brought his face closer and shuddered at the sudden wave of new smells mixing in from Katsuki's quirk.

If before the blonde's scent was a mix of sugar and spice, there was now an added note of burning and smoke, elevating the sweetness to Izuku's heightened senses.

Then he bit down, and he thinks this is what heaven must taste like.

The taste of Katsuki's blood remained the same saccharine taste, with an added spike of burnt sugar that assaulted Izuku's tongue.

He wasn't sure how long he tasted and drank and sucked, but eventually he felt sparks from Katsuki's palm and pulls away before they burn his face.

Izuku looks up and almost preens at the hazy look in the blonde's eyes, his body swaying back and forth as if a simple gust of wind would topple him over.

Izuku leans down to lick the wounds close, glowing green eyes locked with crimson.

"Thank you, Kacchan. Happy Birthday," He whispers against the healed wrist.

Katsuki scowls but doesn't pull away, still relishing in the weird energy thrumming along his skin just like last time.

"Whatever, nerd."

Izuku smiles, wide eyes crinkling at the corners, "Will you let me again, Kacchan? Bite you? Please?"

There was that hypnotic note to the greennette's voice again that snuck onto Katsuki's mind like a viper, itching to strike. His instinct was screaming at him to fight it, but the buzz overpowered everything else.

"Whatever, weirdo."

Izuku's bright smile was just a bonus.

💧🍷💧🍷💧🍷

The months after that, Izuku came over often. At first, they'll play with action figures or fight about the heroes that debuted and if they could catch up to All Might (no one could).

Then Katsuki would glance at the greennette and the same would follow.

Izuku still drank from the animal blood packets that his mother brought home everyday, but he didn't go through as many as before. When his mother noticed, Izuku beamed at her.

"I solved it, mama! Everything's fine now!"

Inko was unsure and suspicious of the vague answer, but she folded at how healthy and alive her baby angel looked. She thought as well that Izuku must've figured out his.. nature on his own. After all, he was a smart kid.

And if she noticed how often Izuku was going over to the Bakugous (almost everyday!), she figured that her son was simply making friends and couldn't help but be happy for him.

Inko was so elated that she failed to notice the subtle glow in Izuku's emerald green eyes whenever he got back from the Bakugous, or the splatters of dark liquid on the sleeves and collar of his shirts.

💀 ⚡ 💀 ⚡ 💀 ⚡

Izuku's 4 years old when the doctor tells him he doesn't have a quirk.

It's been years since he was taken to one, but after months of showing no quirk like pulling objects or breathing fire, Inko begrudingly brought him to the hospital.

He cries. He watches the All Might video clip of saving a hundred people and cries. He clutches at the All Might figurine Katsuki gave him for his birthday and cries.

When Inko sees him, she runs and hugs him and there's rain falling again from her eyes.

That day he finds out that the rain were tears and that the world was unfair.

And when Katsuki shoves him away the next time they meet, disgust painted across his features, Izuku mourns for the first time.

He mourns for the blood he'll never taste again.

💀 ⚡ 💀 ⚡ 💀 ⚡

Middle school was...

It was something he didn't want to repeat, that's all. Izuku doesn't regret meeting All Might and being chosen as his successor. He doesn't regret the grueling training he was put through to be able to handle at least 1% of the power he was given.

What he regrets was Katsuki, his former best friend.

For a couple years after being declared quirkless, he still clung onto the title. Even with the shoving and the bullying, he got back up and ran after the blonde.

Middle school was...

It was different. Things escalated a bit further. The shoves and bullying became worse, and sometimes Izuku's mocked by the smell of burnt sugar before there's an explosion by the side of his face.

He knew he was fully capable of getting away. After years of testing out his nature, he knew he was mentally and physically superior to most humans.

But he could never raise a hand against Katsuki. Because when night comes and he slips into an exhaustion-led sleep, Izuku's dreams are plagued by the phantom taste of saccharine blood and the smell of burnt sugar and spice.

He regrets, during the small moments between dawn as he wakes, of ever drinking Katsuki's blood.

💧🍷💧🍷💧🍷

"-ya, Midoriya. Problem child, are you done daydreaming?"

Izuku jolted out from his thoughts, his face flushed as his other classmates snickered. He opened his mouth to apologize, but promptly shut it when Aizawa glared.

"If you're done, why don't you explain why the Hero Commission remains as a private enterprise despite the call for legislation to transform it into a government agency in 2100?”

“Though the legislation was in the works to be passed then, numerous hero agencies and freelance heroes had no desire to be labeled as government workers resulting in the biggest pull-out of membership since the Hero Commission was founded,” Izuku fiddled with his pen, mind racing to recall the material.

“But that’s not all. Another reason the legislation fell through was due to the controversial proposal to include a provision that barred non-‘humans’ or at least non-humanoids from registering with the commission should it be made into a government agency.”

Aizawa raised a brow, crossing his arms, “You’re sure it was a controversial proposal?”

Izuku frowned, pondering the question. “It was and it wasn’t, sir. In 2097, there were still segregation sentiments against the non-humanoid quirk users, but at the same time, the movement for equal treatment was gaining traction.”

The greennette gulped when black eyes bore down on him, the pressure seemingly deafening with the sudden silence of the class.

Just as Izuku was planning to haul himself out of the window (he’s a vampire, he’ll survive... he thinks), Aizawa clicks his tongue and walks back to the front of the classroom.

“You’re at the top of the class, problem child. Don’t let me catch you daydreaming again.”

“Y-yes, Aizawa-sensei! U-understood!”

Aizawa grunts and glares at the rest of the class who were, most if not all, slack-jawed at Izuku’s spitfire answer.

“Oi, why aren’t you taking notes?”

There was a scramble of papers and the scratching of pens, but Izuku’s attention was on the person in front of him, just as it was a couple minutes ago before Aizawa outed him.

In his defense... Katsuki’s neck was looking so so pretty today.

When the blonde had entered earlier, Izuku swears he almost had a heart attack (which would be a whole new level of concern considering his heart wasn’t even beating).

There must’ve been an explanation on why Katsuki’s wild, spiky hair suddenly changed into a clean-shaven undercut with the top fluffed up.

If there was, Izuku’s sure his subconscious heard it because he wasn’t sure his mind could process anything else besides scattered thoughts of hair, fluff, neck, yum, bed, fuck, pull, yum

So! If it wasn’t for Katsuki’s very very pretty and delicious-looking neck, Izuku wouldn’t have been singled out! Honestly, he should demand retribution for this.

Yes. Definitely.

Green eyes roamed the expanse of Katsuki’s neck, swallowing the drool gathering in his mouth. He followed as a bead of sweat trailed from the newly-shaven area down to the base of Katsuki’s skull until it disappeared into the uniform’s collar.

Izuku’s considering if he should file a proposal to get rid of school collars. Maybe.

He gets a whiff of Katsuki’s perfume, the musky scent mixing in with the familiar sweet scent of sugar and spice.

Izuku looks down at his notebook and sees a rough draft of the proposal, complete with pros and cons. Though, he needs to fix it up because he’s pretty sure Principal Nedzu wouldn’t accept the reason of ‘so I can see more of Bakugou Katsuki’s pretty neck and maybe bite it if I trip’

His phone buzzes in his pocket.

Glancing at Aizawa, whose new victim was a sleeping Kaminari, he opens it and almost dies.

Kacchan: stop staring you dumb fuck. I can feel your eyes drilling into me, fuckface.

Izuku dies because his mind is assaulted by Katsuki being drilled by not his eyes but something thicker, longer, and would feel so so good as he took a handful of the tuft of blonde hair–

“Alright, that’s the end of class. It’s lunch time for you and nap time for me,” Aizawa snapped the book shut, giving one last glare to the class before skulking out.

He has never been more thankful for the lunch bell.

💧🍷💧🍷💧🍷

“Soo... Deku-kun, that was something, earlier, huh?”

Izuku stopped mid-bite into his katsudon, looking up to see the knowing grin on Uraraka’s face.

“Uh...”

“Come on, Deku!” She grinned, her brown eyes glowing hazel for a moment. “I know you weren’t daydreaming at all. Now, come on! Spill the tea! This spirit needs some gossip!”

“T-There’s nothing to g-gossip about!”

“Deku, that’s exactly what people say when there is something to gossip about.”

“She’s right-kero. I can literally taste your guilt across the table, Midochan.”

“Ugh, not you too Tsu-san!” Izuku groaned when she just grinned and fist-bumped with Uraraka. He turned to Iida, eyes pleading.

The stern-faced member of the Dekusquad™ just adjusted his glasses. “I apologize, Midoriya-kun, but I have to agree with them. You really do reek with guilt and, if I may say, a great amount of sexual frustration.”

Izuku gaped, torn between blushing out of embarrassment and wanting to drown himself in Todoroki’s soba.

Somehow sensing the threat to his meal, the red and white haired boy beside him shuffled away with an arm placed around the bowl protectively.

Todoroki stared at him with a deadpan look. “Izuku, don’t drag me into this. It’s your fault for fantasizing about the human in the middle of a class filled with supernatural creatures.”

Izuku pouted, but couldn’t refute it.

The moment he walked into 1-A’s classroom back in first year, he just knew. And the same went for the rest of them.

The first couple weeks, they skitted around each other, no one really bringing up the elephant in the room. That was until Kaminari tripped in the changing room and turned into a freakin’ bird before he fell on his face.

After that, Izuku got introduced, day-by-day, to what each of his classmates were.

There were some who proudly announced what they were to the whole class after the Bird Incident™; Kirishima introduced himself as a samebito, Ashido and Tokoyami as night demons from distant branches, and of course, Kaminari as a thunderbird.

Others took a longer time, Izuku included, since each of them either had a pretty rough history or were taught (like Izuku) to never reveal themselves.

When they moved into the dorms, though, most became lax. One day, Izuku walked in the bathroom and almost had a heart attack when Sero’s neck stretched and popped off. It turned out that Mineta, a gnome, planned the prank which he deemed a success.

If a success meant that Izuku squealed like a little girl and almost fainted on the bathroom floor.

Others’ revelation were mixed into the conversation; Uraraka and Jiro were chatting about the wind currents of the day and the gossip the latter heard, Aoyama mentioning a cousin named Raphael, Yaoyorozu warning Izuku to watch out for corners just as he bumped into Katsuki.

There were others that Izuku had to guess from observation alone as he never found the time to talk to them about it; Koda was an easy guess when he sprouted a couple of branches to weave bird nests, Ojiro’s single tail sometimes split into 3, 6, or 9, depending on his mood, and Iida almost killed him (not that he could die) when Izuku shook him awake and got spiky wings in his face.

The ones that took particularly long were those that were unusually tight-lipped about their natures, but Izuku was nothing if not determined (and nosy as fuck as Katsuki would like to say).

In the case of Sato, it was pure coincidence– or fate, according to Yaoyorozu. It was one of the nights when Izuku was plagued with nightmares of distorted faces and gas masks. When he jolted awake, the very very last thing he expected to see was Sato looming over him, looking to be chewing black smoke coming from Izuku’s head.

The greennette was kind of proud for not screaming or following the impulse to punch his classmate in the face.

Todoroki and Asui were by pure coincidence as well. Izuku had just finished training in the forest near Ground Gamma, when he sensed their presence nearby. Curious (of course he was), he followed their scent.

Once again (and why was this becoming a trend), Izuku saw his life flash before his eyes when a crazed Asui lunged to tear his throat out. In a blink, she was encased in an ice cage, the temperature making her drowsy.

Todoroki rarely showed emotion most of the time, but Izuku felt completely chastised under the disappointed stare of his friend.

Izuku was one of the last ones to spill the beans to the class, with Hagakure and Shoji admitting that their quirks made up for the deficiencies of their natures.

On record, Izuku admits that he was manipulated and that he had to be bribed a lot of All Might merchandise to stop him from sulking weeks after.

Why? It was because during one of their il(legal) dorm parties, someone spiked Izuku’s drink, bringing his defenses down from his instincts.

Instincts that were honed into one thing and one thing only: Bakugou Katsuki.

He was pretty sure there was a betting pool on what kind of creature he was, but Izuku’s proud that they didn’t expect to see him attempting to feel up and publicly molest their resident explosive human. Ha! Take that!

The proud feeling stuck by him even as he woke up with a hangover, the collar of his shirt singed, and one of his fangs missing.

Izuku groaned and thumped his head on the table, the katsudon set aside and forgotten.

“Ochakooo, what should I dooo?” He whined, emerald green eyes zoning in on the familiar tuft of blonde hair.

“It’s the hair isn’t it?”

The resounding thump on the table gave her the answer.

“Mhm, it’s a good look-kero. Mina said it makes–“

“Kacchan’s neck seem like a meal from the gods that’s meant to be worshipped and prayed to before it’s dived into and devoured?”

“Um... I’m pretty sure Ashido-san said it makes Bakugou's ‘eyes pop’, but, uh, yeah, what you said, Midoriya-kun,” Iida coughed into his hand with the other two girls giggling.

Izuku groaned, head shifting on the table to get a better view of Katsuki. Gods, if Izuku didn’t know better, he’d have thought his childhood friend was the reincarnation of a god.

The blonde sat at Bakusquad’s™ table, his trademark scowl on his face. But the universe must be mocking Izuku today, because Katsuki’s back was to one of the windows and the greennette had to watch as rays of sunlight caressed golden locks and the very bare neck that haunted his dreams.

The sight made him remember those dreams– the innocent ones where he’d be swaddled in Katsuki’s warmth and scent of sugar and spice, soft and lazy kisses exchanged in between the sheets.

Then there were the not-so-actually-not-at-all-innocent ones. Dreams where soft and lazy kisses led to rough, deep, and dirty ones, with Katsuki’s tongue fucking Izuku’s mouth with a heated fervour. And the vampire would return the favor by littering the writhing body underneath him with nips and deep bites, leaving Katsuki to be a beautiful, breathtaking sight covered in blood, all helpless and his.

Katsuki shifted in his seat and the angle made the sun hit the fluffy tuft of hair and Izuku’s hands itch to run his hands through them, gently. At first.

Then he’d grab a fistful and pull, swallowing the keening sound from Katsuki’s mouth as his free hand caresses and squeezes the blonde’s neck, relishing in the bruises that would blossom beautifully.

Todoroki sighed, setting down his chopsticks. “Izuku, you’re doing it again.”

“Ah... he’d look so pretty covered in bites, hm?”

“Oh my god, just fuck him already.”

💧🍷💧🍷💧🍷

Bakugou Katsuki was the only human in their class.

So by virtue of a serious talk (which was honestly just their separate group chat), the class decided to reveal themselves to their explosive human. It was only right after all, to be come clean to a future coworker.

They thought it’d be easy since the class wasn’t exactly subtle about hiding their natures, their guard going lax with the knowledge of being in other creatures’ presence.

Plus, it was Bakugou, you know? He was an observant asshole.

Oh my god, they were so wrong.

“Hey, Bakubro!” Kirishima grinned, flashing his shark teeth.

“Shut the fuck up and go away.” The blonde grumbled, plugging in his earphones.

“Hey, hey, come on, man! I got something to tell you!”

Katsuki looked at him with a deadpan stare that rivaled Todoroki’s.

“Is this another one of those shitty dad jokes? Because if I hear another as bad as How do you weigh millenials– in Instagrams I will fucking explode your ass to the goddamn moon.”

Kirishima snorted, “You gotta admit, that one was gold.”

“You know what else is gonna be gold, shitty hair? Your fucking tombstone.”

Kirishima opened his mouth, ready to retort, but shook his head. He had a mission to do!

“Come on, Bakubro! I swear this isn’t a joke. It’s uh,” He scratched the back of his head, “It’s kinda serious?”

Katsuki stared at him, hands hovering above his earphones. With a huff, he threw them aside.

“Alright, spill it out, bitch.”

“Uh, okay, so...” Kirishima cleared his throat and looked at the blonde dead in the eyes, “I’m a demon.”

The redhead went through classes that day with a black eye and Izuku could only pat him on the back consolingly.

💧🍷💧🍷💧🍷

If telling Katsuki, a human, that supernatural creatures existed was proving to be impossible (and dangerous, judging from Todoroki’s singed hair), there was another thing that was proving to be impossible in their class:

Quenching Midoriya Izuku’s thirsty ass.

Or, more accurately, his thirsting for Bakugou’s ass.

Another sigh escaped the vampire’s lips as he longingly– Sero gagged and Shoji looked like he wanted to stab his only eye– stared at the human.

Some that had a keen strong sense of smell, looked ready to jump out the window as Izuku continued to reek with conflicting feelings– sadness, longing, guilt, love, lust (the last one in particular growing strong whenever Katsuki bent over to pick something up).

Everyone could literally see, since day one, how the vampire was smitten, head over heels, in love– whatever the term was for this sickening display of a kicked puppy.

And they weren’t blind to see the same expression on their resident human, who looks over his shoulder just as the greennette would duck down to take notes.

Which was every few minutes.

The pining, longing looks, and the unresolved sexual tension between the two made even Yaoyorozu want to just kidnap them and shove them in a closet together.

(The plan was actually deliberated upon once, before it was shut down after the Kamino incident)

So here the class was, 3 years in, with a horny pining vampire and an equally horny pining human, both skitting around each other but never crossing the line.

Uraraka wants to crash a wrecking ball through that goddamn line.

18 creatures locked eyes across the room and exchanged solemn, determined nods.

If their two resident idiots wouldn’t move their asses, they’d do it for them.

💧🍷💧🍷💧🍷

Izuku’s phone pinged as he got out of the shower. Putting on a simple All Might tee and shorts, he dried his hair as he swiped the device open.

Urasylph: Deku-kun! Hey!! It’s movie night! Momo got a hold of that All Might movie you wanted

Urasylph sent a photo.

The vampire couldn’t help but squeal at the sight of the Golden Age film that only a few fans got a hold off because it was only released in the US.

Sending a quick affirmative to Uraraka, Izuku bounced on his feet as he waited by the elevator.

Ohh, I wonder what the plot for this one is! There were talks in the forums about a love interest introduced, but that’s so unlike All Might’s other movies. I wonder if they’ll talk about his new moves–

The elevator dinged.

And all thoughts about All Might were crushed into dust by the onslaught of sugar, spice, and smoke that assaulted Izuku. He stumbled into the metal box, mind hazy and disoriented.

It was only when the elevator dinged and the doors closed that he realized where exactly he was and who exactly was with him.

In an enclosed space. With Katsuki.

Izuku dug his fingers into his arms and shifted away from the blonde, stopping himself from getting any closer to the tantalizing temptation that was his childhood friend.

Yes, Izuku, remember, childhood friend.

Yup, childhood friend, childhood friend.

Childhood friend whose blood you’ve tasted.

Yes, yes, childhood friend who had the most addicting blood and made the most delicious and hypnotizing sounds when Izuku sunk his fangs in and sucked–

“Jesus fuck, Deku, stop with the fucking staring,” Katsuki growled, crimson eyes glaring at the vampire. “And shut your stupid muttering, shitty nerd.”

Izuku gulped, licking his dry lips. “Uh, sorry, Kacchan.”

The blonde was looking at him weirdly, making Izuku shift against the side of the elevator, tension crackling between them.

He tried (really, he did) to keep his eyes on the numbers that counted down, but before he knew it, his traitorous eyes were back on Katsuki.

And Katsuki’s eyes were on him.

Izuku trembled under the gaze of those pretty, dangerous eyes that shone so much like pools of blood. He felt his fangs tingle and his mouth dropped slightly, tongue flicking out to his dry lips.

Crimson eyes followed the movement before locking with emerald green eyes that looked to glow for a second.

Katsuki gulped and Izuku took a step forward.

The elevator dinged.

Katsuki shook his head and shoved past Izuku, hightailing it the fuck out of there.

There was that weird feeling thrumming just under his skin again whenever he felt the greennette’s eyes on him.

As if he was a meal worth devouring, bit by bit. He wasn’t sure if the feeling in the pit of his stomach was relief or disappointment when he walked out.

It took Izuku a couple moments after Katsuki stormed out of the elevator to snap out of it, stepping out quickly before the doors shut.

Though honestly he wanted to stay right there in the metal box to have a serious talk with his vampire side. Like, hey how about not wanting to attack his childhood friend every time he was in sight, hm?

And then maybe he’ll move on to an intervention for his dick that refuses to recognize the situation of movie night with friends and that it shouldn’t be up and awake.

Alas, he did promise to show up and Izuku’s nothing if not a good friend who keeps his promises.

💧🍷💧🍷💧🍷

His friends were assholes and he regrets not staying to talk to his dick in the elevator.

“Aww, we’re sorry, Deku-kun! We didn’t think everyone would come tonight.”

There was an apologetic tone to her voice that Izuku would’ve bought if it wasn’t for the wide grin on Uraraka’s face.

The vampire sighed, “It’s fine, I can just sit on the floor–“

The spot where Izuku was headed to melted.

“Oh sorry!” Mina grinned, looking not sorry at all. “My hand slipped.”

Izuku opened his mouth, ready to launch into an hour long lecture as to how that wasn’t an accident at all, but Katsuki just grabbed his arm and dragged him.

“Fucking Deku, just sit your ass down so we can start already, Christ.”

The blonde shoved him on the beanbag– the only unoccupied cushion in the whole room that was placed in the darkest corner of the room. The whole thing reeked ‘sus’ but before he could think more about it, there was a weight on the seat and–

Oh shit, shit, shit.

The beanbag sank with both their weights and Izuku was conflicted between strangling and hugging the one who made physics.

Because now Katsuki was glued to the vampire’s side, with his bare legs almost tangled with Izuku’s, arms sticky with sweat flush against him.

The movie starts and the lights turn off, enveloping the room in darkness, save for the light of the screen.

Was he being tested? Maybe. Was this punishment? Maybe. Was Izuku still breathing? He brings a hand to his face and feels a gust of air. Yup, still breathing.

Now, if Izuku’s heart was working he knows it would’ve stopped by now because ohmyfuckinggodimtouchingkacchan. And then he looks at his hands and agonize over how awkward they look just sitting there, clasped together on his lap.

So he tries moving them around– resting on his legs, interlaced on his chest (that was stupid and reminded him of Dracula). He was going to try stretching his arms and folding them behind his head, but he felt a sharp pain by his side.

“Relax, shitty nerd. You’re moving too fucking much,” Katsuki grumbled, eyes on the screen. “Just enjoy the movie, dipshit.”

As if by command, Izuku feels his body relax and eventually thoughts of their position gets pushed back in his mind with the movie starting the action scenes.

After All Might delivers a new move– the Arizona Chokehold– Izuku gushes and turns to the side to point it out to Katsuki and–

Oh.

Katsuki’s face was rid of his trademark scowl, his crimson eyes relaxed and shining with excitement as it followed the movement on the screen. Some blonde locks fell over the human’s eyes, making them pop out in the darkness. Izuku’s eyes trailed over the blonde’s face, lingering on Katsuki’s upper lip that shone with sweat despite the blast of the AC.

Green eyes followed the drop of sweat fall from blonde locks to the newly-shaven undercut, down down towards the familiar jugular.

And Izuku’s assaulted by this deep, deep, primal hunger as his eyes zoned in on the beat of the vein that beckoned to him like a sultry dancer.

Bite me. Suck me. Own me.

The vampire’s nostrils flared, green eyes darkening at the heavy scent of Katsuki’s musk mixed with the smell of shampoo that failed to mask sugar and spice from permeating.

No, no, Izuku. Control yourself.

Izuku took a shuddering breath and unclenched his hands, wincing at the crescent marks that remained. He could feel his fangs elongated, drool threatening to spill from the corners of his mouth.

The greennette tries shuffling away from the blonde to try and clear his head from the incessant mantra of bite bite suck suck filling his head. After all, he prides himself in his restraint and self-control.

Then Katsuki moves and Izuku thinks he sees his self-control flying out the window.

The blonde was now half lying on the greennette, his leg tangled between Izuku’s, the rest of his upper body leaning against the vampire’s chest.

And Katsuki’s neck is in front of him, the long expanse of skin bare and covered in a thin sheen of sweat that glowed under the light of the TV screen.

He spends exactly one second to think of the repercussions and the setting of the whole situation before his rational mind just throws its hands up and leaves.

Izuku breathes and his body shudders from the heavy cloak of Katsuki’s scent covering him.

Leaning forward, he stops before dip between the blonde’s neck and shoulder and plants a soft kiss. Katsuki tenses, and Izuku freezes, mind running through every excuse in the book (and maybe planning out how to migrate to America).

Katsuki shifts and suddenly, he’s on Izuku’s lap, head inclined slightly to the side, as if hesitant.

Izuku’s still frozen, mind at a halt at the sight before him– Katsuki, the silly beautiful human offering himself like a delicious little thing to the vampire.

Katsuki grumbles and moves, grinding his ass down on Izuku’s dick.

Izuku snaps.

He grabs a fistful of blonde hair and pulls roughly, lunging at the expanse of skin, feeling the blood pumping through it like a siren’s song. He scrapes his fangs along the juncture and preens when Katsuki whimpers and melts into the greennette.

Izuku peppers the blonde’s neck with soft kisses mixed with harsh sucks and nips, not deep enough to draw blood but almost. His other hand sneaks up Katsuki’s tank, fingers brushing against perky nipples.

The motion draws out a moan from the blonde, and Izuku nips at the spot below the human’s ear harshly as a warning.

Looking up from Katsuki’s neck, he sees the movie still playing, the dark figures of their classmates still lounging and facing away from them.

“You’ll keep quiet for me, won’t you, Kacchan?” Izuku murmurs and blows lightly on the human’s ears, earning the vampire a delicious shudder that went through Katsuki’s body.

“You–“ Katsuki’s growl turned into a mewl that went straight to Izuku’s dick when the greennette twisted one of the blonde’s nipples as he gave a harsh suck at the jugular.

“Shh, Kacchan.” Izuku pulls at another nipple, this time giving a harsh bite near Katsuki’s shoulder, groaning as the blonde moaned and grinded down on his cock.

He let go of Katsuki’s hair, and uses it to grip the blonde’s hip as he thrust up. Izuku muffles his moan into Katsuki’s neck, fangs dripping with drool onto the warm skin, the spark of pleasure spiking through him as he thrust against the tight fabric of their clothes.

And Katsuki, the beautiful human, moved against the vampire in turn– grinding down as Izuku thrusts, mewling and clutching at the seat beneath them when the greennette’s nips and kisses turn into harsh sucks and deepening bites.

Izuku aches, aches to sink his fangs deep into the sweat-covered neck, to fill his mouth again with the saccharine blood that haunts his dreams, to suck and bite and see his human covered in blood and marks.

There was this primal itch deep in Izuku’s soul to mark his human, his Katsuki– to see crimson eyes glazed and pupils blown as Izuku sucked and thrust into the warmth over and over until only his name spilled from the blonde’s lips.

But he forces himself to slow down, to pepper kisses and licks across the expanse of Katsuki’s neck. His hands roam the rest of Katsuki’s body, mapping the well-formed muscles of his back and chest. His fingers brush teasingly at the perky nipples, Katsuki’s annoyed growl shifting into whimpers.

“You– ha, you shit.” Katsuki bites back a moan as Izuku moves his hands down to the blonde’s ass, giving the tight globes a squeeze.

“St–stop, teasin– ah!” Katsuki goes lax against vampire as Izuku spreads the human’s ass and gives a harsh thrust against the crease.

“Kacchan, Kacchan,” Izuku pants in Katsuki’s ear, tongue lapping at the lobe. “Can I bite you? Please? You’ll let me, won’t you, Kacchan?”

He thrusts up again at the question, nipping along the dip in Katsuki’s neck. Katsuki’s head swam as waves of pleasure and pain overrode his senses with every nip, every suck timed with a pinch and a twist of his nipples, followed by a strong thrust of Izuku’s clothed dick against his ass. He feels close, so, so close and he inches his hands towards his straining dick, wanting to reach that climax.

But then everything stops.

Katsuki couldn’t stop the whine crawling its way from his throat as his body chases the sensations wrenched away from him. Scarred hands hold his wrists down to the side, and he feels Izuku’s breath along his ear, sending shivers down his body.

“You didn’t answer me, Kacchan.” The vampire licks a long stripe from Katsuki’s shoulder to his jugular, giving the point a strong suck.

“Can I bite you, Kacchan?”

Katsuki feels something sharp– something dangerous scrape along the most vulnerable point in his body and his breath hitches. He turns his head and meets glowing emerald green eyes, with red bleeding through them.

He licks his lips and Izuku’s eyes follow, hunger evident in the green orbs. In a smooth motion, Katsuki grabs a hold of green locks and shoves the vampire’s face in his neck, grinding down at the same time on the thick, straining cock beneath him.

“Got your fucking answer, shitty Deku?”

Katsuki feels smug at feeling Izuku’s cock twitch, but the feeling was shortlived when he feels the sharp canines at his neck again. Izuku chuckles, the sound dark and deep and went straight to Katsuki’s cock.

“Thank you, Kacchan.”

That was the blonde’s only warning before Izuku sunk his fangs in Katsuki’s jugular, blood filling his mouth, the saccharine taste mixed with spice and smoke overwhelming the greennette.

Katsuki gasps and shudders, body going lax and crashing against the firm chest. Hands snaked beneath his shirt and palmed the wet spot at the front of his shorts.

The blonde was reminded of the haze that wrapped around his mind, his eyes half-open, mouth gasping softly with every suck. He absently noticed the blood that dripped and pooled down his tank, the liquid raining down like a waterfall.

Katsuki didn’t notice, his mind and body caught in the sweet spot between the constant crashes of pleasure and pain with every suck, every thrust against him, every tweak and pull of his nipples.

Izuku’s hand snuck into Katsuki’s shorts and the human jolted and moaned as cold hands started a rough pace, with every stroke of his cock accentuated with a sharp thrust beneath him. Katsuki’s head lolled to the side, resting against Izuku’s shoulder, hooded crimson eyes glazed over as he rode along the motions.

There was a sharp pain on his neck, then the blonde whimpered at the tongue that lapped soothingly, licking up the trails of blood and the wound until it closed.

“Kacchan, Kacchan,” The vampire moaned and grunted in Katsuki’s ear as he grasped at the human’s hips and thrust with fervour, his other hand getting rougher with the blonde’s cock. He pushes his thumb against the leaking head and Katsuki moans, panting and thrusting into Izuku’s hand.

Izuku swipes against the head again, gathering the precum, and moves towards along Katsuki’s length to his balls, and his finger circles the tight ring of muscle.

“Kacchan,” He murmurs in the human’s ear, mouthing along his neck, “Come for me, Katsuki.”

With another bite, he pushes a slick finger in and curls it. Katsuki’s eyes snap open and moans, hips riding Izuku’s finger until he feels his balls tighten and he comes, his cock spurting the white liquid into his shorts.

When he finishes, Katsuki slumps back down, breath going hard. Even as Izuku pulls his finger out and fixes them both up, crimson eyes blearily watch, the haze still cocooned around his mind.

Katsuki sees emerald green eyes look down at him lovingly and a warm kiss against the corner of his lips, before he succumbs to the darkness.

💧🍷💧🍷💧🍷

“Holy shit.”

“That was...”

“The hottest thing I’ve ever seen?”

“The equivalent of one of those forbidden wet dreams?”

Everyone looked at Todoroki who shrugs and peruses the stack of DVDs on the table.

Iida clears his throat. “Well! I declare this a mission success for operation ‘Izuku’s Thirsty Ass’!”

Then he frowns, “I can’t believe that’s a sentence I would have to say in my life.”

Asui patted him on the back. Sero entered the room with a tied up Uraraka and Jiro in tow, both pouting at not being able to eavesdrop on the two that just left.

“So, uh, I’ll turn in early, guys! I have to uh–“

“Dude, almost everyone here is going to rub one out too. Don’t even bother with the excuses.”

“... It was pretty hot.”

Everyone averted their eyes from each other, Kirishima and Ojiro adjusting their shorts, with Yaoyorozu crossing her legs.

Their dreams were going to be interesting that night.

💧🍷💧🍷💧🍷

Katsuki blinked his eyes open and frowned. He was back in his room, if the scorch mark on the ceiling was any indication.

He groaned and moved to scream into his pillow because what the fuck was that another dream fucking hell–

“Oh, Kacchan! You’re awake!”

Katsuki’s eyes jolted open and flipped over, facing Izuku who sat by the foot of his bed. The greennette’s hair looked wilder than usual, looking like someone purposely ruffled and pulled at it.

Oh, right. That someone was him.

Right, they should probably talk about it.

“What the fuck, Deku?”

Nice one, Katsuki.

Instead of a whimpering mess that the blonde expected, Izuku just gave him a lazy grin (shut up, he wasn’t blushing) and moved closer.

He fingers one of the loose threads on Katsuki’s boxers (making him realize he was cleaned up, and no that didn’t make his heart flutter, assholes).

“Mhm, sorry, Kacchan. We didn’t really get to the fucking part.”

The way Izuku said the word ‘fucking’ sent heat spiking to Katsuki’s dick and he scrambles to get a hold of the situation before he ends up as fucking putty in the nerd’s hands again.

He huffs and crosses his arms. “Stop changing the subject, fucker. I knew you had a weird oral fixation and biting thing when we were kids, but what the fuck?”

Katsuki brings a hand up to his neck and shivers at how sensitive the whole area feels. He catches Izuku staring at his hand, a predatory look in his eyes.

Izuku stares for a few more moments before shaking his head and smiling.

“Oh, yeah,” He scratches his head, “I’m a vampire, Kacchan.”

Katsuki blinks. Once. Twice.

Then he lets of an explosion at Izuku’s face, which the fucker avoided. Fuck, the asshole even had the gall to pout at him– pout!

“That wasn’t nice, Kacchan.”

“Lying ain’t nice either, Deku.”

Izuku sighed exasperatedly. He leaned forward and Katsuki flinched at how close he was, scarred arms caging him in against the headboard.

“The obliviousness was cute at first, Kacchan. But...” The vampire smiles, flashing his fangs that glinted menacingly. “It’s getting tiring being doubted, little human.”

Katsuki gulped and shifted on the bed, trying to hide his growing erection. Glowing green eyes flitted down and red bled into them, the heat of the gaze making the human’s heart thunder in his chest.

Izuku shifted onto the bed and between the blonde’s legs that easily parted. He lifted a hand and cupped Katsuki’s face, crimson eyes fluttering close at the touch. He leaned in and gave him a soft kiss, gentle and slow.

The greennette broke away to breathe and crimson eyes fluttered open. “Wha–“

“I like you, Kacchan,” He gave another quick kiss and grinned. “Go out with me?”

Izuku loved seeing Katsuki covered in blood and his marks. But what the vampire loved more was seeing his human blush from head to toe, curses spilling from his swollen lips.

”Go fuck yourself, you bloodsucker.”

“Mhm, I’d rather fuck you, though,” Izuku nuzzled Katsuki’s neck, blowing against his ear. “Katsuki.”

The blonde shivered and moaned as Izuku nipped at his ear, grounding his hard cock against Katsuki’s.

Izuku kisses the blonde hard, finally tasting blood from those lips where beautiful moans and sounds came from. He pulls back and licks the blood from his lips.

“I’m still thirsty, Kacchan.”
