Todoroki may be immortal, but there's a smiling redhead who might still be the death of him.

This is both a Spooky Season thread and a /very/ late birthday present for the lovely @/GoldenGirl1016 enjoy https://twitter.com/GoldenGirl1016/status/1314284360892321795?s=19

CW: #nsfw, #todokiri, background bkdk, American College AU, shitpost energy, Todoroki's hair is not canon, dumb boys, fluffy, age gap??, size difference, lots of dialogue, top!Kiri, bottom!Todo, blood (not graphic), cuddles

It took a second; but eventually, it clicked why his eyes were scanning the same paragraph over and over: it was nearly 10 a.m.

"Why does this always happen. You have a timekeeping device. Use it."

Turns out, grumbling to himself wasn't the greatest idea given it drew the attention of a mortal who may or may not be turning into a problem.

"Hey dude! I didn't realize that was you! Why are you wearing a hood? Ashamed of being a redhead or somethin'?"

Kirishima. The embodiment of sunshine.

The irony was not lost on the recluse now being torn from his rather dry reading.

"Hello, Kirishima."

"Stop calling me by my last name, man. It's weird."

"Excuse me. Eijirou."

"There you go! Anyway, what are you up to? I never see you around this early."

"I was actually just leaving. You can have this table if you'd like."

"What? Oh... well, why don't I walk with you!" The look of disappointment may not have lasted very long, but Todoroki didn't want to see it ever again; so he agreed to being followed by the world's largest puppy out of the library.

On their walk, nearly everyone took the time to greet Kirishima while completely ignoring Todoroki. The latter didn't mind that situation in the slightest; but apparently, that wasn't very clear because, by the time they got back to the dorm courtyard, Eijirou was apologizing.

"I doubt they meant anything by it. You're great. It's probably just hard to get to know you when you don't come to any events."

"That is a choice, Kir-- Eijirou. But I appreciate the concern. Now if you'll excuse me."

"No way, man. I said I'd walk with you. Don't make me break my word."

Damn that smile.

"Fine."
'But then you have to get out of here,' he added to himself.

They walked into the lobby of his building to find a mess of limbs and mouths on the couch.

"Gross, Kat! You have a room!"

The blond to whom he was apparently speaking didn't look up before displaying the back of his hand with only the central digit extended. Based on the reaction it got from Kirishima, Shouto assumed it was an insulting gesture.

"Oi, watch it! Move yourself or I'll move you both."

Finally breaking free from the neck of his partner, the blond just sneered: "Why because you're /so strong/? Get the fuck out of here, dude."

The breathless, green-haired man in the blond's lap smacked his lover's chest before speaking up himself: "Sorry, Ei. We just got a little carried away."

'One could certainly say that. Have modern humans no scruples?'

Pulling his partner off the couch, he continued: "But we should actually be getting to my afternoon class. Bye Ei, bye... Ei's friend."

The two left, adjusting clothing and laughing quietly to each other on their way out; and when Shouto looked back to Eijirou, there was something... tender there.

'No. Cease. /Mortal./ Remember what that means?'

Yeah, the internal lecture wasn't working; and Eijirou turning to him again only made the issue worse.

"Ok, I think this is sufficient."

"No way! You're so secretive. I've been dying to see what you're hiding away in there. Worried I'll find a dead body or something?"

"Only yours..." Shouto mumbled, and luckily it was so quiet Eijirou didn't hear.

"Come on!"

'You are a fool,' his mind supplied as they finally arrived and he carefully unlocked his door.
"Ok; so if I let you see my room, you'll leave?"

"Ouch. Am I really that terrible?"

'No. You're an Adonis.'
"No, of course not. I'm tired."

"Tired? It's not even noon. You've got to work on that sleep schedule, dude. I know were college kids, but seriously."

He opened the door and let the beast of a man into his space before following and removing his hoodie over his head.

"Woah."

Shouto spun around, hands covering the part in his hair: "What?!"

There was a blush across the taller man's face, but that didn't really indicate if there was actually a crisis or if he had just made a bigger fool of himself by acting like there was.

"Uhhh... Sorry that was... Your... shirt rode up and... well I've never seen you in the gym so it just surprised me how ripped you are, man."

Todoroki wasn't sure what 'ripped' meant in this context, but it sounded like a compliment.

"Thank... you?"

"Oh man, sorry if I made it weird," that massive hand was combing through the spikes on his head in nervousness; and the situation was becoming more critical by the second. "That was actually one of the things I wanted to ask you: what's your deal man?"

'Damn it. You should've been more careful. Your behavior unnerves the--'

He was broken out of his self-criticism by Eijirou's clarification: "Like, are you single? Got a girlfriend? Boyfriend?"

'Oh.'

"Uhhhh... I guess single would be the most accurate description. Why?"

"Well, I'm glad I haven't been as obvious as I thought. I want to ask you out."

'Oh no.'

"Shouto?"

"I do not think that's a good idea."

"Oh, shit. Are you straight? I'm sorry. I guess I shouldn't have assumed based on how often you dye your hair."

He laughed, embarrassed; but Shouto was focused on that last part.

"Dye my hair?"

"Yeah. I mean, you don't vary much from white and red; but you must spend a ton on hair dye, dude."

'This is... Not good. How careless have you been??'

"Fuck. I'm making it weird. I'm sorry. I'll leave you alone and just tuck myself into my grave."

Shouto's alarm at the last comment must have been apparent in his face because Kirishima rushed to clarify, "It's a joke! Don't worry: I'll recover. I just feel like an ass."

That pained face was back and it made him do something stupid: "I don't dye my hair."
'IDIOT!'

"What? So you have an evil twin or something?"

'DON'T ANSWER THAT!'
"Not exactly."
'MORON.'

"Care to elaborate?" His earlier embarrassment was still simmering under the surface, but that smirk was drowning out Todoroki's internal shouting expertly.

"Well, I would; but then you might kill me."

"There you go. Now you're getting a sense of humor."

'It's not a jest, you glorious specimen.'
"I'm also not sure what you meant by straight."

"Ok, that's enough jokes. You've got to quit while you're ahead, dude."

"I'm not joking."

"Huh. Ok, then sorry about that. It's a little hard to tell when you don't change your expression or tone much." There was a beat before the crimson blush returned and he frantically added, "Not that it's a bad thing! It's one of the things I like about you, actually."

Unsure of how to respond, Todoroki just waited for him to define the unknown term; but Kirishima didn't speak until he'd started closing the gap between them.

"If you aren't sure what straight is, we could test it."

Mildly confused but interested, Shouto nodded.

Kirishima leaned down close enough that his breath played over the smaller man's cheeks that were surely reddened if the heat behind them was any indication.

So much for trying to stay detached enough to keep his inner voice from stabbing him.

"I never noticed: your eyes are different colors. That's beautiful."

"Thanks."

"Can I kiss you?" the question was breathless in a way that indicated this wasn't an everyday thing for the other man either. At least, he hoped it wasn't.

After a moment of consideration, his mind acquiesced albeit begrudgingly: 'Why not. We have to move again anyway.'
"Yes please."

It had been a while since he allowed himself this form of connection, and he honestly just hoped he didn't ruin it with his lack of practice.

Based on the fact the strong hands now on his hips tightened slightly, he couldn't be that bad. Right?

"Ok." Kirishima breathed against his lips, "Chances are, you aren't straight."

"If you say so," Shouto whispered back. "Does that mean the experiment is over?"

Neither pulled back in the silence that followed, but there was an added tension there as they each tried to read the other's mind.

"It can be. But if you'd prefer it continued, we might need to remove that turtleneck. Otherwise, I can't be held accountable for damages."

Remembering why he had to wear higher collars in the first place, Shouto tried to remain calm as he responded: "Understandable. Allow me a moment first."

At that, they finally broke apart. Kirishima stood patiently as Todoroki grabbed one of his dark bottles from his fridge and darted to his little bathroom.

Ignoring the fact the mirror reflected nothing but the wall, he guessed he had already started showing signs of white at the roots of his hair.

'Better safe than sorry. Drink it. Even if just for his sake.'

He hated it. It was always hideously bitter when cold, but he didn't exactly have another option. Opening the bottle, he drank half of it before taking a breath. At least that way the taste didn't kick in until the last minute.

Kirishima must have heard him retch and cough because he was knocking at the door.

"Hey man, you ok? I'm sorry if I went too far. I can just go if you want me to."

"No, it's ok; just give me a second." His voice sounded foreign and thick as he tried to regain his composure.

He opened the door after a moment to a paler Kirishima. "My apologies if I worried you. I just had to take my medication, and it is incredibly unpleasant."

That seemed to comfort him slightly as his body relaxed. "Oh ok. I didn't realize you took medication. Are you ok?"

"Yeah, I'll be fine. I should give you a heads up though, there's a mark on my neck. Just do your best to ignore it."

Eijirou made a face that made Shouto want to laugh even though he wasn't exactly sure why.

"Kinky." When the only response he got was a raised eyebrow, he backpedaled: "Nevermind. Sorry. Sounds good. Does that mean... the turtleneck is coming off?"

"You are shameless, sir."

"I don't take full responsibility. I now know what's under there so..." he retorted, trailing off in favor of a shrug.

Shouto rolled his eyes; and feeling 20 again (well, /actually/ 20), he noticed the heat increase in his face again as he pulled the shirt over his head.

"I'll be damned..."

'Probably.'

"...You're really hot, dude."

"I thought you already had come to that conclusion. Which is why you followed me here in the first place."

"Okay, you didn't have to expose me like that."

"I haven't exposed anyone but myself."

Eijirou laughed at that, and Shouto was fairly certain he had missed something. Why must language continue to evolve? Especially the bastard that was English. He could never keep up with it.

That train of thought didn't last long, however, given that the embodiment of the perfect male figure was now removing his own clothing.

"How far should I go?" that stupid smirk was back, and Shouto was reminded how terrible of an idea this was.

"I guess we'll just have to find out."

In his haste to kiss the other man again, Shouto knocked them both into the bed causing Kirishima to fall into a sitting position to keep from toppling completely.

"Sorry... I haven't done this in a while."

"That's ok, man. You being so eager is flattering." And once again the room was dazzled by those perfect teeth.

Luckily Kirishima reached up to him to preserve the mood because Shouto was always a little disoriented after one of those smiles.

And then their lips were connecting once again. It was... sensual. Both of them seemed a little nervous to take it too far but also desperate to continue.

Shouto let his fingers trail over what was essentially a brick wall underneath him, and Eijirou's hands took that as an invitation to roam as well. When they made it from his cheek to where his neck met his shoulder, Shouto hissed.

Eijirou pulled back to see why and chuckled: "There's that mark then. Get a little carried away in someone else's bedroom?"

"No! I--"

"Dude. You don't have to tell me, it's fine. It was just a joke. Looks like you had fun though. Good for you."

Shouto grumbled a bit at that but dropped it. Despite the fact that there was something about this redhead that made him want to spill all his secrets, he wouldn't.

For example, he /wouldn't/ tell him that the year 1874 contained the worst day of his life. He also, /definitely/ wouldn't admit he had not been intimate with anyone since 1967.

The mortals had had a bit of a sexual awakening that decade, to say the least, and he wasn't /completely/ invulnerable.

Not to everything at least. And top of the "weaknesses" list was currently this ridiculously popular college boy.

"I will try to avoid it though if it's sensitive," Kirishima assured, rubbing the smaller man's arm to punctuate the sentiment his face was already communicating.

Realizing someone was talking to him again, Shouto was broken from his self-deprecating musings. He nodded and went back to admiring all of the hard work Kirishima had done in the gym.

"You're making me blush. Looking at me like I'm a whole meal."

"Excuse me?"
'Do NOT eat him, you bastard. You have already caused enough problems.'

"You /really/ don't understand slang, do you."

"...no."

"Alright, I'll work on that then. I just meant you're looking at me like I'm the most attractive thing you've ever seen. It's flattering, but it's making me blush."

'Why not just say that then? Meal already has a meaning.'
Trying to quiet his internal grumblings about the fickle nature of linguistic expression, Shouto attempted to flirt in return: "Maybe I like it when you blush."

It must have worked because Eijirou was humming against his lips in a kiss and pulling him down into the bed.

They were then laughing into each other's mouths as they situated their limbs. They eventually got into a comfortable position: Shouto kneeling above Eijirou and straddling his core; and rough hands snaked into the red hair falling in short curtains around his lover's face.

"I hope you aren't ashamed of your scars. I actually think they're great. Shows you've survived."

Shouto wasn't sure why Kirishima was so much more talkative than his previous suitors had been, but it was... nice.

At least, his /mind/ thought so. His dick, not so much.

"How is it that you can look like that," he shifted his weight to lift one hand and gestured at the defined muscle moving with each breath, "and still be so sweet? Everyone loves you, and I can't tell if it's because of the first reason or the second."

"Probably boff," Kirishima managed to admit despite being cut off by cool lips against his own. That was probably a pretty good indication of Shouto's impatience, and Eijirou was happy to oblige.

He flipped the both of them and, after a questioning glance that Shouto answered with a quick nod, worked Shouto's jeans down his legs.

"These too?"

Another nod, and the boxers came down too. There was a slight whistle from the man above him that Shouto was pretty sure was meant as a compliment, so he blushed.

"Wait... You've done this before right? I don't take V-Cards like this."

"Proper English, please."

"Have you had sex?"

"Yes. But it's been... a while."

His laughter echoed around the room before he responded, "It couldn't be that long ago dude. You're like 19."

'Ok sure, warmth personified. You keep thinking that.'
"Regardless, I'm rusty."

"That's fine. And last question: are you a bo-- do you prefer to be..." Eijirou hesitated, clearly trying to avoid the wording he had been about to use; but now his face was twisted in an awkward smile as he rubbed the back of his neck.

He took a breath before continuing, "Who's... penetrating."

"That's a valid question. You can decide. I don't have a preference."

"A fellow man of versatility, I see. I'll enter you then, sir."

'Are we being mocked?'
"Hey! It's not my fault I don't know all your nonsensical words!"

"I'm kidding! It's cute. Oh come on, don't pout. Do you have condoms and /lubricant/?"

When he heard the dramatic way Kirishima pronounced the final word, Shouto hit him with his leg.

"Ok ok I'm sorry," he laughed before kissing the smaller man beneath him. "But honestly, do you have stuff."

"Third drawer," Shouto indicated.

Kirishima got up and opened it before laughing again. "Wow. /Fancy./"

Not that it mattered at this point, but he had completely forgotten his oils were in an ornate glass bottle.

"I don't see any condoms. Can I just promise I'm clean instead?"

"Yeah, that's fine."
'It isn't like your illnesses would infect me, anyway.'

Eijirou walked back toward the bed, opening the bottle on the way. He then closed it again and set it aside after realizing he was still wearing clothing.

Shouto now understood the whistle from earlier, because he nearly mimicked it when shorts and underwear hit his floor.

He was glorious, and Shouto had plenty of time to contemplate that fact while he climbed back onto the bed and reached for the bottle he had set on the side table: muscles flexed and relaxed in waves.

By the time the oil was being poured onto thick fingers, Shouto was embarrassingly desperate. That apparently came across /very/ clear in his response to Kirishima's "Ready?" because the bastard was laughing again.

"Ok, then relax. I know what you mean by liking my blush though. Red looks good on you."

Shouto may have whined at that point, but he couldn't be sure because that was when Eijirou pressed the pads of his fingers against his entrance.

No thoughts were had at that point. Only pleasure, and he hadn't even /done/ anything yet.

"We should do this more often."

Shouto had said it to himself after finally getting his bearings, but Kirishima chuckled like it was for him as he pressed one finger deeper.

The smaller body jolted as another embarrassing noise slipped from his open mouth.

Worried for a moment he was being selfish, Shouto tilted his head to look up: Eijirou was enjoying himself just fine, his erection was proof of that.

"You really /haven't/ gotten any action if one finger is doing this much," he teased before pressing a second one in along side the first.

Shouto would have protested if Kirishima weren't right, but there wasn't much of an argument. His moans just continued as Eijirou continued to prepare him for what pleasure was to come.

Then Shouto remembered he had hands and reached up to grab at the man who was too far away for his liking. The following laughter vibrated his ribcage as their chests connected and lips trailed down his jaw.

He may have been turned into a mess, but Shouto was certainly not complaining.

Their cocks brushed against each other and that broke what little control Kirishima had managed to maintain through their build-up.

"Alright. Ready?" it came out in a breathless whisper, and Shouto was pretty sure he had never heard anything so beautiful.

But it didn't compare to the noise that followed: he had nodded and almost immediately Kirishima left him empty to exchange his fingers for his cock. As soon as the warm head slipped past Shouto's rim of muscle, Eijirou nearly crushed him as his arms struggled to keep him up.

And then that /groan./

It almost made Shouto want to turn him just so he could hear it forever.

Luckily, he was more than a little distracted with the pleasant stretching that accompanied Kirishima bottoming out.

"Fuck. Sho." whatever he had wanted to say after that being swallowed up by a deep kiss as arms wrapped around his broad shoulders.

"Please move."

"Oh, right."

It was slow, but that was probably for the best considering the risks of Shouto losing control.

As the speed built slightly, so did that previously forgotten sensation of pressure in his abdomen. Kirishima's breathing picked up in time and his grunts told Shouto what he needed to know before he even spoke: "I'm... shit, you're tight... I'm gunna... FUCK!"

There was a pulsing within him, and Shouto bit down on his own arm to prevent the alternative as his eyes rolled back and he followed suit, dirtying his own chest with his release.

Uncaring of the mess, Eijirou crushed Shouto in an attempt to gain his breath.

Unable to breathe himself, Shouto gently hit at the arm caging him in.

That was when Kirishima noticed the blood.

"Holy shit, dude! What happened!"

"What? Oh... I think I bit myself?"

"Good God, then your teeth must be even sharper than mine. Are you ok? Do you want help cleaning up?"

"No that's ok. Just... don't go."

At that, Kirishima made a gesture with his hands that Shouto hoped meant he would stay; and now slightly assured, he made his way to his bathroom on shaking limbs.

After taking a moment to clean both his legs and arm, he came back out to find Kirishima curled up in his bed. He was uncertain of how to proceed until one red eye opened, and a large hand indicated the spot next to him under the blanket.

"That was great," he mumbled into damp hair as Shouto curled into him, dwarfed by the man now trying to stay awake.

"I agree. But like I said, I'm very tired. Want to just sleep here for a bit?"

"I'd love that."

Few words were exchanged after that as they let themselves enjoy the haze that came after encounters like this. It almost made Shouto forget he would have to be packing soon.

Unfortunately, Kirishima's first comment as they finished their nap reminded him: "Did you... get up while I was asleep to dye your roots white??"

'Look what you've done.'
"Uhhhh... No. It just... changes."

There was a pause that Shouto was very uncomfortable with until Kirishima responded brightly: "Cool! Want to go get some food?"

'Huh. Maybe relocating won't be a requirement after all...'
"I'd love that."

[AN: These silly boys are so fun to write. I hope you enjoyed their banter this thread took itself in a different direction than I outlined, but I'm still happy with how it turned out.]

Happy Halloween, treat a writer to some attention or American currency http://Ko-fi.com/princesa_incognita0864

Also, if you're curious about the hair thing: basically the concept is it turns white (starting at the roots) if he doesn't consume enough blood. He's a full-on redhead if he stays on top of it tho
