You laugh boisterously, your dimples sinking into your cheeks as you beam at him, “How else do you want me to say it? Is that not what would be happening?” 

“Yeah but do you gotta use the word spurt? It’s…” he hesitates. 

“Fine. Would you rather me say ‘Katsuki will you please ejaculate all the sperm saved up in your testicles into my vagina so that you can fertilize the egg in my uterus?’” 

“You’re a fucking nightmare ya know that?” 

How long has Katsuki been in love with you? He actually can’t pinpoint it. In fact, he may only be realizing it now as the thought of you wobbling around pregnant with his kid fills his mind and makes him look like one of those sappy in love guys in the romance manga he reads. 

“So is that a yes?” 

He shoots you his signature “I’m bein’ serious” face and you laugh again, filling the room with your joy.

“Oh come on Katsuki. Look I promise, you won't have to do a thing after I get pregnant. I won't ask you for any help or child support or whatever. The kid doesn't even have to know you’re their real dad,” you say now looking serious as you explain.

That gives him pause. Are you saying this because you don’t want to be with him? He wouldn’t force himself in the kids life if he agreed to do this, not if you didn't want him around. That desperation in your eyes though. Why don’t you get it? If you asked him to catapult himself to the moon, he’d fucking do it. 

“I know you’re focused on getting to number one and you're super close and…Katsu I hope you know I would never do anything to get in the way of that but…my window is closing real soon. And I have the opportunity now and obviously I am painfully single right now so…”

Oh. You think he doesn’t want this. You think you’re burdening him. Damn…all this time he’s known you were clueless but for the love of shit you can’t be this clueless. Katsuki hasn’t had a date in…two years? Yeah that’s it. And in those two years he's spent almost every day with you, hangin’ out, goin’ on trips, watching movies, doing mundane life shit. Hell in his mind, the two of you are practically married already. 

But it’s clear you don’t think the same. Maybe you don’t see him that way? Which means… this entire thing could get real real messy. 

Katsuki squints, “You’re serious? Like you're sure you want this?” 

“I’ve never wanted anything more than I want this.” 

He knows that’s the truth. It’s all you ever talk about when you both talk about your goals and dreams. He wants to be number one and you wanna be a mom. But still the question remains, would you wanna be a mom to his kid? 

“And you’re sure you wanna do this…with me?” he asks again.

You shrug nonchalantly, “Why not? You’re my best friend. I trust you with my life. This is just as precious.” 

Goddamn you saying sentimental shit like that so nonchalantly. It’s like your fucking superpower. 

“Yeah but what if…shit gets weird after,” he stammers, raising an eyebrow. 

“Why would it get weird?” you ask with wide eyes.

“Cuz…yannow how weird it gets when two friends start fucking. Look at Sparky and Hanta. It’s been off since they hooked up last month at Mina’s party,” he explains, throwing his hands up in frustration.

“Well I don’t know how you do it, but I wouldnt consider you jacking it into my pussy would qualify as us ‘fucking’”, you say curling your nose up in judgement.

“I'm bein’ serious,” he retorts, bumping your forehead lightly with his palm.. 

“So am I! Look we’ve been through…so much shit together. My mom’s death, All Might’s death, the hero charts, breakdowns during the middle of the night while I try to get my degree, the very very bad break up with the one we do not speak about…none of that got the better of us so I don't see why this would either.”

Katsuki looks away from you now, Eyes dropping to the floor. He almost chokes when your tiny hand curls around his chin lightly and makes him look back at you. You’re wearing that expression again, the “you’re the only one in my universe” expression he’s seen you use as a weapon to bartenders to get you both free booze. 

But this time, there’s no tricks.  

This time, you mean it. 

“Hey, I mean it. You’re my best friend. I’m not gonna  lose anyone else so if you’re completely against it, tell me and I’ll drop it right now,” you assert.

Katsuki sighs and plops a hand on top of your head, rubbing gently to make sure he doesn’t mess up your hair. 

“Gimme some time to think about it alright? It doesn't mean No. It means I gotta…prepare…I guess.”

 Your smile returns, along with your irresistible ass dimples. “That’s totally fine! I won't start ovulating until next month anyway so take all the time you need!” you chirp. 

You both continue down the hallway, your apartments located toward the end of the hall. When you reach his door, you pause before heading a bit farther down the way to your place.

 “Hey Katsu?” 

“What now?” Katsuki asks exasperated as he pulls out his key. 

When he turns to look at you, you’re staring at him with the big wide serious eye again. You look a little nervous, anxious as you twiddle your fingers in front of you. Geez he’ll never get over how fucking pretty you are. 

 “Thank you. Even if you refuse, thank you, for at least considering it,” you say bowing graciously to him.

His heart thumps in his chest but he shakes it off quickly and bumps your forehead again playfully. “Tsk, dumb ass. You act like I don’t always consider the crazy shit you come up with.” 

The playful jab soothes you again, and just like before the anxiety melts away into glee. 

“Crazy shit?!? Admit it, I make your life fun and exciting. If it weren't for me you’d be at home watching “How It’s Made” videos on Youtube,” you say sticking your tongue out at him as you brush past to onward your apartment.

“Fuck you! That shit is interesting I don't care what you say,” he calls after you as you laugh and skip away. 

 Katsuki watches your swaying hips as you go. He’s definitely got a lot of shit to think about tonight. 

Never have you ever found a ceiling more interesting than right now. 

Ok, it’s not all that interesting but you are surely going to act like it is. Refusing to look Katsuki in the eyes as you lie on your back in his dark ass bedroom, legs spread with the string of your underwear cutting into your plush soft waist is by far the only way to keep this entire situation from becoming more awkward than it already is. 

You suppose the best part of looking at the ceiling is that it’s not your own. You're at Katsuki’s apartment and of all the times you’ve been here, all the nights you’ve spent here you’ve never looked at his ceiling. Your mind wanders as the sound of fabric shifting idly becomes the background noise in your mind. 

“The ceiling that interestin’?” A gruff voice says from the end of the bed. 

God it’s like he’s in your head, which again shouldn’t be a surprise. There’s literally no other person in existence who knows the way your mind works better than Katsuki. He is your best friend after all. 

Your eyes shift to him and immediately you find it to be a mistake. He’s shirtless, the black sweatpants he wears are low on his hips and goddamn…have you really never noticed how tiny his waist is compared to his broad ass shoulders? And… has he always been like… that fit? 

No. Bad. Stop that. That is not where this is supposed to be going. This is a business deal between friends. Nothing more. 

In a desperate attempt to keep the mood humorous, you scoff. 

“Actually ceilings are really sexy so I’m trying to concentrate and get in the mood and you’re ruining it,” you reply, letting your eyes reluctantly fall away from him and return to the ceiling. 

You can practically hear the way he rolls his eyes, “Let’s just hurry and get this shit over with. Sooner we do it, sooner this stops being weird,” he huffs, moving closer to the edge of the bed. 

His anxious tone should make you feel bad but strangely, it’s comforting. It’s good to know you’re both feeling the same way. 

This is a big thing you’re asking of him, and you know he’ss been on the fence about it since you asked. Honestly, you expected him to say no. But when he’d accepted, a few days ago you’d tried to ignore the way his reply of “When have I ever been able to say no to you,” made your stomach do flips. 

“Thanks again Kats. For agreeing to this. I’ll probably spend the rest of my life paying you back for it,” you say gently, still avoiding looking at him. 

He huffs again, but you hear the hesitation, the hitch in his breath at your soft confession. He taps your knee and waits for you to give him your attention again. 

Again it’s a mistake, looking at him, because his expression is soft and tender it makes your lips part in a gasp. 

“Pay it back by bein’ a good mom to the kid,” he mutters quietly. The searing touch of his hand on your knee makes you swallow a lump in your throat. Something about Katsuki referring to you as a mom makes a bubble of emotion rush its way to your tear ducts but you bite back the sob with a smile. 

“I promise.”

“Alright, I’m comin’ to ya. Ya ready?” he asks and slowly you nod. 

With a low groan, Katsuki crawls on the bed between your legs, nudging them more apart so he can fit comfortably between them. With his body hovering over yours it makes this feel more real. 

You are about to do this. You are about to be impregnated by your best friend. 

Katsuki was nice enough to let you change into a shirt of his that’s way bigger on you than a regular shirt. It drapes down over your ass and covers your panties. But while lying on your back  with your legs spread and him between them you can’t help but feel more vulnerable than if you were wearing your own clothes. He’d said it would help you feel “less exposed” but in the back of your mind you wonder if he gets off on seeing girls in his shirt before he fucks them. 

That is another forbidden thought you shouldn’t have. You’re not like the other girls he fucks because he is not “fucking” you. He’s going to jack himself until he gets right to the cusp of orgasm and then insert himself to finish inside you. 

It’s hardly sex. More like… helpful masturbation at this point but still…him being inside you… that’s…something different. 

“Alright uhh… if you’re ready I’m gonna… take it out now,” he stammers nervously,as he stares into your eyes. 

Your eyes flick down to his groin and then back up to his eyes. Another desperate attempt to lighten the mood falls from your lips. 

“With your pants still on? Like this is a quickie?” you say in mock shock. 

Katsuki growls in frustration. His brows pull together and he pouts his lips.  

“I’m doin’ it for you! Plus, I thought it’d be weird if I was butt ass naked jacking my dick over your fully clothed body so shut it!” 

You shake your head in defiance, “Hold on now! First of all, I’m not fully clothed. Second, I told you to do whatever you need to be the most comfortable. That’s why we’re at your place, Katsu. So if ya need to take our pants off, just take ‘em off for christ sake!” you glare back at him trying  not to smile. It’s your typical banter with him. He tries to make you comfortable. You yell at him and tell him to worry about himself. 

Nice to see you two can still fall back into the groove of friendship. Which is why you know after this, the two of you will be ok. 

“Fine! I’ll take em off then! But you gotta take your stupid panties off too. If it’s about my comfort, pullin’ em to the side is annoying as shit,” he yells, moving off the bed to slip his pants down his legs. 

You notice, he’s not wearing underwear and as you lift up to slip your own underwear down your thighs and ball them up to place next to your head, you avert your eyes from Katsuki’s –admittedly impressive–cock. 

When you both are back into position–you on your back with the shirt pulled over your now full out pussy and Katsuki leaning back on his thighs with a pillow over his junk–you’re both breathing heavily. His skin is hot against yours as his thighs brush against your inner thigh. You stop the tremble that starts up your spine and try to focus on the ceiling again as Katsuki’s hand moves between his own legs.  

You hear him clear his throat, and say “I’m startin’ now,” and then inhale as his hand wraps around his cock. 

He closes his eyes, which you appreciate. It means you can look around if you want to and in a second of courage you take the chance to observe his technique. 

Ok so yeah… Katsuki is fucking hung. Not a fact you thought you;d ever know about him. It’s like the two of you don’t swap sex stories but he’s bever gone into detail. He’s hot, you know that and so does he, but you never thought his dick could be another reason why it’s so easy for him to get laid when he wants. 

His waist is enviable and his abs ripple down his torso. He’s got a happy trail of brown hair that gradually grows into a bush of blond coily hair. With his eyes closed you’re also able to get a good look at his dick. Katsuki’s got massive hands and it still looks like he’s  having trouble getting his entire palm around the girth of it. It makes your mouth water–although it shouldn’t. 

And naughtily you believe his may be the thickest you’ve ever taken.  

“Uhh…” he pauses, his eyes are open and yours quickly flit away from his cock and up to his eyes.  He looks worried which is good because it means he didn’t catch you looking at him. 

“What?” you ask breathlessly. 

He raises an eyebrow and then both brows furrow again and the hand that’s not still on his cock drums against his thigh nervously. “You’re breathing is all weird and shit you—“ 

“Just hurry up and jack it Katsuki,” you interrupt wanting to divert the attention away from your dumb ass horny inappropriate thoughts about your best friend. 

He smirks as if he knows what you’re doing but only jokes and says “Heh never thought I'd hear that said to me before.”

“Oh my god, would you just–” You don’t finish because he tips a bit off balance while he’s sitting back on his knees and balancing on his thighs and feet. When he rocks off balance, he grabs your thigh to steady himself and the action makes you gasp in delight. 

The moan that would come after is thankfully trapped in your throat by a wall of disintegrating control. As if he didn’t hear it at all, Katsuki steadies himself, mutters an apology and gets back to it. 

As his hand moves slowly up and down his shaft, you notice it stays a bit boneless in his palm. His eyes are closed again, his face is craned up to the ceiling and his body is shaking as he furiously keeps stroking to get himself there. After about three minutes you cover your eyes and grab his wrist to stop him. 

“Are you…like…okay?” you ask, shielding your eyes to respect his privacy. 

Katsuki groans, “It's harder than it looks!” he spits in annoyance. 

In an attempt to quickly soothe him you put both hands up in surrender and forget the reason you were shielding your eyes in the first place . 

“Hey I’m not saying it’s not! I Get it alright I just…” your words trickle off as you stare at him again, propped up on your elbows.

This time he doesn’t cover himself which is odd. And what’s even odder is you don’t shield your eyes again. He’s got that “i’ve got an idea” look but it’s paired with a guilt only you’re able to recognize. 

“Do you want me to help?” you ask in a whisper. 

Katsuki’s eyes widen, his cheeks blush red and you can tell for a split second he contemplates saying yes before he sputters out  “…no! I don't need any damn help.” 

You smirk, “You hesitated.” 

He shakes his head roughly, the spiky hair on top of his head shaking like leaves on a tree caught in a storm. “No no just shut the fuck up and let me focus. And cover your eyes back up.” 

“I could…take the shirt off or something if that will help?” you suggest. 

This time he does visibly hesitate and think about your suggestion. He probably thinks since you brought it up, it’s more acceptable to agree. 

Plus…you know your strengths and your rack is definitely one of them.  

Finally he relents, “…fine.” 

The shirt is off and over your head in seconds, leaving you Winnie the Pooh-ing it in a black bra.. He looks away, trying not to look at your pussy but you notice the quick glances and the way his dick twitches at the sight even more. This time, you cover your eyes, electing to give Katsuki a chance to look at you and get himself going.

As it turns out, not being able to see him but being able to hear him proves to be even more sexually stimulating. Katsuki’s hand sounds wetter now, making lewd noises as his hand rubs up and down his dick. His breathing is different too, it’s heavier, littered with more sharp inhales and hissing. You even think you hear him mutter to himself. 

You lick your lips, is the difference just because he can see your tits now? Or maybe he’s not even looking at your tits. You are pussy out right now. Maybe he’s looking at your cunt. Maybe he’s fantasizing about when he will get to put it i–

“Look I uhh… I hate ta ask but can I uhh…” his voice pulls you out of the spiral of thoughts plaguing you. 

You peek at him through a sliver between your fingers, “Can you what?” you inquire.

“Can I touch you?” he asks quietly, the blush spreading over his cheeks again. 

You’re a little confused. Why wouldn’t he touch you? How does he expect to like… do the whole “impregnate” thing without touching you. You’re sure you already gave him the consent. But as you watch him nibble on the dead skin of his bottom lip and his eyes flit to the sheets and sneak glances at your tits, you understand what he means. 

“Oh! Ohhh. Umm yeah…yeah whatever helps,” you say brightly, trying to encourage him you’re ok with it. 

“I'll stop as soon as you say,” he relents. 

“Ok.” 

His hand hovers nervously over your tit, he flexes his fingers as he readies himself. You become hyper aware of your budding nipples in the chill air of the apartment. They poke through the fabric of your bra and you’ll admit you want him to just get it over with and grab it already. 

When he does, his hand is so warm it shocks you and you intake a sharp inhale. Immediately he tears his hand away

“What?! What did I hurt ya or—“ His eyes are wide and he almost leaps off the bed in worry. 

You shake your head, “No no! I just…nothing, it's fine. Just keep going,”you assure him. 

How the hell do you tell him that felt way too good? Way too good for your best friend to simply grab your tits. You won’t. That’;s a dirty little secret you’ll keep to yourself. But when he goes to grab them both and massages them deeply you realize our body might be more of a tell than you thought. 

There’s a moan yo-yoing in your throat. A fierce visceral moan that begs to be released, especially when Katsuki hums and starts to stroke himself again. Setting a nice pace of grinding his fingers into the plum flush of your tits, flicking your nipple to elicit light gasps from you, and stroking his now noticeably pre glistened cock, you try your best not to let a peep come from you. 

The last thing he needs is to feel even more awkward after having to ask to touch your boobs for help in getting it up. 

It worked though. He’s definitely up. And damn… was it always that mouth watering to look at when you first saw it? 

Mouth-watering is not the best word to describe your best friend’s cock if you’re trying to avoid catching any complicated feelings. 

Which you are so you whisper a silent scold to your brain to get it together. 

Katsuki’s hands on you make it so very difficult to keep up this ruse of not being completely and totally tuned on. Your eyes are squeezed shut, your bottom lip is tucked between your teeth and your fingers are digging into the mattress at your sides. 

You think he’s caught on to your act when he stops again.  

“Alright what’s the deal? What's with the face and the noises?” he growls. 

You shake your head, “Just keep going! It's fine!” 

To your dismay he doesn’t budge, “It don't look fine ta me!”

God why can’t he just take the hint and keep going! 

“I'm just trying not to make this all awkward ok?!?

“It’s already awkward!”he insists.

“Yeah well I'm trying not to make it even more awkward! Like you're doing now! Maybe that should be your superpower, the ability to make something awkward even more awkward.” 

“Shut up! Look you can't not tell me what's going on with ya. You need ta talk to me if we’re doin this. I can't tell if you’re uncomfortable or whatever if you don't say someth—

You can’t believe this is happening right now.  Katsuki is literally sitting with his dick out arguing with you. God do you really have to say it to him? 

“I'm not uncomfortable! I'm just trying not to moan Katsuki!” you shout at him, blowing an exasperated and embarrassed sigh that makes your lips push out in defeat.

 He blinks and jolts back as if surprised. “What?” 

Defeated and now basking in the pure shame and guilt of the moment you groan, “You’re standing over me jacking your dick and fondling my tits! It’s…erotic. And this is not supposed to be an erotic encounter so for the love of pete just keep going so we can get this ov–” 

“Don’t…don’t be silent…” he says now with an expression that is dangerous. Very very dangerous because that is not the way you’d look at your best friend you’re only trying to impregnate as a favor. He’s looking at you like… like he wants you. 

Now it’s your turn to blink in confusion. “What?” 

Katsuki huffs, this entire ordeal finally getting to him, “Look you want me to fucking jack it, right? Listening to moans helps so…ya don't gotta be quiet.” 

He reaches out and lets a finger trace your nipple and you arch up into his touch and let out a breathless sigh that sounds like…heaven. He nods, muttering a sexy “mm hmm that’s it” to himself as your back straightens again. 

Oh fuck is this so much easier when you have the ok to let loose. When he touches you now all the hesitation is gone, between your legs slick dripples from our cunt and as Katsuki’s pace on his cock quickens your moans get louder.  

You don’t even have to tell him he can touch your bare chest, he just shuffles one of your straps down to expose your tit and palms it as he moans.  

“My hand cold?” He asks when you jolt at his touch.

“N…no…it’s…so warm…” you pant. You have to bite your lip to stop yourself from begging him not to stop. Not only are his hands warm, they’re surprisingly soft. A bit calloused from the hero work but soft as he handles your tits with care. 

He smirks, “Good.” 

Your sounds of pleasure fill the room now, mixed with the lewd wet noises of Katsuki’s hand on his cock, you’re sure it probably sound like you two actually are fucking. Espeially when he leans over to gently blow on your nipple. The tip of his tongue flicks it for just a second, only giving himself a tiny sample of you without taking it to far. 

He knows you like it because your moans become gentle coaxes of his name, “Mmm…ah…I…umm Katsu…I Uhh…” 

His name dribbling from your lips seem to be the catalyst because his breath hitches again and he finally announces, “I’m getting close…I’m getting close I—I should put it in now” 

He’s leaking from the tip of his cock and he has the goddamn nerve to rub the head through your folds and tap your clit before he lines himself up. He’s gotten too comfortable or maybe..he’s a little lost in the sauce right now. When you glance up to look at him, his eyes are already on you. 

In fact his stare is hot, piercing as he locks eyes with you. Your lips part again and he bites his own. Is it insane to think about kissing him right now? Slowly he enters you, pushing past that first ring of muscle in your pussy and fucking hell you were right about him being the thickest you’ve ever had. You feel yourself open up and part around him as he slides in.  You’re so full you swear you can feel him in your stomach and it’s absolutely slutty of you to arch your back and dip your hips forward so he’s embedded even deeper. 

The best part though is watching him as he presses his hips forward. He throws his head back and groans loudly. And the sigh of pure contentment and pleasure that bubbles in his chest is to die for. It’s like…he’s been waiting years to feel this, instead of the frenzied horny dazed minutes of him fucking his own fist.

“Holy shit you’re tight. How come you feel so…oh fuck…” he moans wantonly, his question caught in his throat. His gravelly tone is littered with soft desperate little whimpers you're sure have never breached his lips before. 

Your legs are shaking. 

Unbelievable. 

He’s only just bottomed out, hasn’t moved an inch and your legs are fucking shaking. Every sensitive little nerve in your pussy is firing off messages of pleasure and ecstasy and completely tuned into the cock stuffed inside you right now. 

How can he feel this good? Is it just because the meds to trigger your ovulation make you more sensitive? Somehow you don’t think that’s the case. There’s electricity shooting up all your limbs as Katsuki’s hands settle on the sides of your waist.

Your lips tingle and you truly believe the only way to stop it is to have his lips on yours. He shifts a bit, leaning over you and trying to angle himself in a way that has your head spinning and your eyes fluttering like a slot machine. 

The tip of his cock brushes lightly against your cervix as if giving it a tiny gentle kiss as a warning for the load he will give you. The thought makes all your limbs tighten, makes a knot in your belly constrict and then snap loose as you clench around him and tumble off a cliff and into pure ecstasy.

Your fingers dig into the sheets at your side, and like lightning he grabs your wrist and pulls them up above your head, intertwining his finger with yours. His body completely covers yours now as his breath washes over your face. He’s staring at you, watching your eyes flutter with a goofy grin and then…

“Oh…oh fuck Katsu—“ 

His lips crash into yours as you speak, his tongue invades, licking and twirling around yours as you hungrily taste him. The tingling in your lips only subsides when he takes your bottom lip between his teeth and nibbles. You find your legs wrapping around his waist, his tiny enviable waist you’d admired only a few minutes ago and nudge him forward with the heel of your foot. 

“Squeezin’ that tight I’m gonna fucking cu–” again he stops himself midsentence as his hips grind into you. He can’t bear to pull out to pound into you, obsessed with the way you’re wrapped around him. So he grinds against the soft warm walls of your cunt, letting you massage his cock before he cums with a roar followed by whispered sweet words in your ear. 

The only thing keeping you from passing out right now, is the occasional twitching of his cock as he fills you. It almost feels unstoppable, he’s growling, whimpering, moaning and mumbling like a drunk man as he kisses your shoulder and as you come down now from your orgasm you wrap your arms around his back and card your fingers through the undercut at the base of his neck. 

The two of you stay that way, wrapped up in each other for what seems like forever before he pulls back to look at you with an expression that makes you roll your eyes in annoyance. 

He’s smirking, giddy like a boy who’s just seen a titty for the first time. He doesn’t even have to say anything for you to know what he’s thinking. 

“Stop it,” you pout with pursed lips and a raised eyebrow. 

Katsuki chuckles, the mischievous proud grin only growing wider. “Stop what?” he tries to ask innocently. 

You try to push him away a bit, putting your palms on his chest but of course he doesn’t budge. “Stop giving me the ‘I just made you cum’ face,” you retort. 

The grin widens even further, if you can believe it. 

He chuckles, “But I did, didn't I? And based on the way you're still shakin’ I’d bet I was a pretty good one.” unbelievably he nuzzles his nose against your cheek. 

“Yeah well I made you cum too and you don't see me smirking.” 

“Maybe ya should.” 

“We should not be having this conversation while your dick is still in me twitching so just shut up and wait a few minutes before you pull out,” you grumble. 

In a slightly uncomfortable but tender moment, Katsuki lies his head on your chest and listens to your heart. He traces a series of moles down the valley of your cleavage absently. 

Your face heats and he laughs again. “So much for it not being weird,” you sigh. 

“Knew it would be,” he mutters.

“And you still agreed?” 

“Puffs, if you thought I was gonna pump a baby in ya and then leave ya to raise it without me, then maybe I should think about gettin’ a new best friend cuz my best friend woulda known I could never do some shit like that. Eijiro is in the running for your spot. He knew,” he explains.

That shouldn't make you emotional, deep down you knew he wouldn’t just abandon you. Especially if the kid is his but–

“But what about Number One and–” 

“Can’t I do both? You’re the one who made it an either or thing,” he says shrugging. 

“But do you even…like me…like that?” you ask, blushing again. Ridiculous, you sound like a middle schooler or something. 

“My dick is literally still in you right now and I just told you I’d raise a kid with you. How many other ways do I need to say it, idiot?” He replies incredulously. 

“I mean… An ‘I like you and wanna date you’ wouldn’t hurt,” you say sheepishly. 

Katsuki groans, “For the love of…” and then he takes your face between his fingers and makes you look into his eyes and replies,

“I like you and I wanna start a damn family with you. There. That good enough?”

you could feel the graze of his teeth, and the roughness of his horns as they rub against you, his tongue swirling circles, leaving trails of warm saliva over skin that he swells by suckling hard. “B—Belph…!” you gasp, tilting your head back to try and look towards the gated exit. it must’ve been charmed by magic you didn’t understand, because once you’d managed to get inside, you couldn’t get back out. your DDD lay just on the other side, though, and you could see Lucifer’s stoic expression every time the phone lit up with another call. “I-I need to…” your arms could fit through the bars, if he wasn’t pinning them down. your hands make fists, and then uncurl, as if you were trying to grab for it, and bite your lip as you stare at the screen. you could imagine Lucifer was robocalling you, unable to find you in the manor.

“Don’t worry, he won’t even think to look here.” Belphegor elicits a breathy moan, pressing his body to yours. his eyes flickered up to the DDD, too, and he allows a lazy smirk to stretch his lips as he presses them in a seal against your collarbone. he shifts his grip, taking your weak wrists together in one palm to push them above your head. this new position freed one hand that he then slipped under the waistband of your jeans, regardless of your gurgled protest. he didn’t even have to unbutton them, digging underneath the fabric of them and your panties to cup your warm sex. you whimper, pushing your back off the floor at the sensation— it’s greedy and uncouth, the tips of his digits hooking underneath your netherlips to anchor his hand there. your thighs clamp together, legs trying to rub and kick between your bodies, but his hand was already between your hips, and there was no pushing him out now. “You’re such a good girl, my brother wouldn’t suspect you’d break his rules, come exploring the attic even though he told you not to. You’re safely here with me, and I don’t have to let you go.” he whispers each syllable, signing his name over your chest with his tongue as if to claim you as his.

“I’ve been waiting… watching for so long… I’ve needed this. I’ve needed you.”

“W—wait,” you breathe out, bucking your hips, squeezing your fists and pushing against his strength. it was no use, you were much, much weaker than him, but you tried to show as much resistance as you could muster, “d-don’t touch… Belphie, Lucifer will eventually find me! I don’t want you to get in more trouble…” you were panting, now, be it from fear or the pleasurable strokes as he rubs his finger pads between your folds, feeling all of your slick, vulnerable sex. you didn’t want to show that it felt good, being played with against your will, but you couldn’t help it if he felt the heat from your blushing cheeks, or the way your cunt trembled under his fingertips. “J—just help me reach my DDD, yeah..??” you bite down, harshly on your lip when he lets out a bestial snort, using his horns and hooking them through your top and bra. with a shake of his head, like a mad bull, he’s shredded your clothes, and nuzzles his face into your breasts, smothering himself with them. your eyelids flutter when he nips at one, delicate bud; it hardens between his teeth, a pleased growl rumbling in the back of his throat. “L—Lucifer might reward you for h-helping, I could even… maybe I can ask him to let y-you out—!” you try to add, but his middle finger slips into your clenching hole, and it spasms in protest as he sets a brutal pace. “B-Belphegor..!! D—don’t..!!”

“You’re so stupid, it’s kinda cute, even.” Belphegor teases, his gaze burning into yours as he rolls your nipple between his teeth, before clamping his mouth down around it, sucking. he makes a loud, smacking sound as drool leaks out of the corners of his mouth, as if he were feeding from you as desperately as a starved animal. he moans, his ring finger joining the middle one to stretch you open further. they pump, knuckle deep, inside of you, and you can feel every subtle curl as he searches for a sweet spot. you mewl his name, pathetic tears in the corners of your eyes. he was rough, but you didn’t think that he was trying to hurt you.

he was just so damn desperate— and you could see a wildfire of hunger burning in his eyes. he couldn’t be gentle, even if he wanted to.
