#i gotta say i didn't expect to be outed as a monster-fucker this early in my tumblr career

Nomu-Sitting

request: This is kinda kinky... but the reader has been desperately horny for a while but Shigaraki has been too busy, so the reader takes matters into her own hands and has a nomu screw her. Shigaraki walks in about half way through and ends up taking a seat to enjoy the show. (Feel free to ignore this, I won't be offended! But like, thank you so much if you do ♡!)

i changed up some things, instead dabi asks reader to look after the nomu he’s supposed to be watching since he has better things to do

warnings: 18+, monster-fucking, dub-con/non-con, voyeurism, degradation, cheating (?)

He… it… the nomu stares at you, unblinking. Well, you’re not sure if it’s staring at you. The tiny black pinpricks of its irises seem to almost go in separate directions. It definitely took notice when you had entered the room, if its low growl and sniffing at the air were any indication – but had no other reaction once you were standing a few feet in front of it. You tilt your head to the side to test your theory and to your childish delight it copies the action, huffing out a breath at your laugh.

With broad shoulders and biceps bigger than your head, the hulking behemoth makes an imposing figure. Even hunched over the way it is, the difference in height between you two isn’t easy to ignore. Dabi’s words of warning ring in the back of your mind: ‘Whatever you do, don’t get too close to it. Not grabbing distance, anyway.’

But the docile giant in front of you is nowhere near as scary as it was made out to seem.

You take a step forward and tentatively reach out a hand to pet the side of its face, just shy of its chin. It responds with a pleased rumble that vibrates up your arm, and cranes its neck to get closer.

What was Dabi even worried about, you wonder, smiling to yourself. The nomu is almost like a puppy. A massive, deformed puppy with the strength to crush a truck with its bare hands but… it’s cute, in its own way - exposed brain matter and all.

The sense of security you tricked yourself into is immediately shattered when you feel a hand grip your waist – so massive in size it easily dwarfs you. Trying not to panic, you attempt to take a step back. “Alright big guy, I think that’s enough for now,” you say, voice light.

You pray it can’t smell fear.

Of course, it doesn’t listen and instead pulls you closer with way too much ease, pressing you right up against its bare chest. Its body is almost uncomfortably warm and you’re not sure if it’s the radiating heat or the threat of harm that has you sweating.

You’re openly trembling now, biting your lip to keep your whimpers in. You don’t want to scare or upset it with any sudden noises; the nomu is strong enough to squish your head like a grape and you’d prefer to stay alive.

This is fine, you desperately try to convince yourself. It’s just curious. It’s not going to hurt you.

…right?

You can’t hold back the whimper when the nomu presses its beaklike mouth against your neck, tongue slithering out to lave against your neck. The muscle is big, slimy with saliva that quickly coats your neck and jaw, dripping thickly to drench the collar of your shirt. You shudder.

Too preoccupied with trying to not dry heave at the feeling of monster spit all over you, you fail to realize the reason it grabbed you. Pulling you a bit closer, it brazenly begins humping you, the movements of its hips becoming progressively more frantic and aggressive. You’re shocked into stillness by the heavy weight of its hard cock rubbing up against your stomach. Even through the layers of clothing, you can tell that it’s much bigger than anything you’ve ever taken.  This is so fucked… a distant voice in your head echoes.

You nearly jump out of your skin when it suddenly lets out a guttural growl, clearly becoming frustrated with the lack of proper stimulation.

“Shh… It’s ok,” you say, voice lowered into what you hope is a soothing tone.

You try to pry yourself away but the nomu responds with a snarl, grip tightening to the point of pain. You wince and immediately give up on moving. It’s obvious that you’re not going anywhere anytime soon.

Despite your reservations, your eyes find themselves shifting towards the tent in the monster’s pants. You gulp, looking around the empty room guiltily. You’d be lying if you said you weren’t just a little curious…

Shaky hands reach down to unbutton the monster’s pants, a feat considering what little space there is between you two. The movement of its hips drag the khakis down until they fall into a heap at its feet. What is revealed has your eyes going wide and your jaw slackening in shock. The veiny column of flesh is massive – almost as thick as your wrist and topped with a large, bulbous head steadily leaking sticky precum that is smeared against your hip with every thrust.

Almost without even thinking, you grab ahold of its dick and begin stroking. The generous amount of precum makes the slide easy, almost slippery. This placates the beast for a short time – enough to at least let you out of its vice-like hold – but soon it’s made clear that your hand is not enough.

Without much preamble, you’re lifted off your feet and turned around, now facing the gray walls of the nomu’s containment room. You let out a surprised squeak and cast a nervous glance downwards to see the head of its dick peeking out between the plushness of your thighs. 

It ruts into the warmth of your clasped thighs for a while before angling upwards, immediately becoming annoyed with yet another barrier- this time it’s your clothing in its way. Large hands begin groping at your pants before tearing into them as if they were made of paper. The flimsy material of your underwear doesn’t stand a chance against the hulking behemoth and they soon join your shorts on the floor in tattered shreds.

You cry out. “Wai- wait, no! Stop! Stop, let me just--”

Your words are cut off when the nomu rears its hips back before pushing forward. The first few thrusts miss their mark, bumping up against your sensitive clit instead, but on the fourth attempt the head of it’s cock catches on the rim of your entrance and that alone has your breath catching and your mind going blank. The feeling of it pushing in soon snaps you out of your daze and you begin struggling anew. You reach a desperate hand behind you but pushing against the monster’s chest felt like pushing against a solid brick wall – utterly pointless.

Even with you struggling and flailing limbs, it manages to work its cockhead past the ring of twitching muscle, and you feel like you’re being split in half with just the tip in.

It’s too much. It’s too much and you need to get away.

But the nomu keeps going, forcing inch after agonizing inch into your tight, (barely) wet heat.

You let out a broken gasp when it bottoms out, cunt clenching down hard on the too-large intrusion and body going slack in its hold. Even with the unnaturally copious amounts of precum it’s producing, the stretch is uncomfortable.

The head of its cock is shoved up against the mouth of your cervix with every push and you’re not sure whether you love or hate it, but it’s definitely a feeling you won’t be forgetting anytime soon. It’s hard to ignore how good the mindless fucking is starting to feel and after two consecutive orgasms, you’re wet enough that the slide of its dick is much easier. Wet slaps echo off the walls of the large, barren room. And for a while it’s the only sound, overlaid by the monster’s grunts and pants and your own high-pitched whining and moans, until the door is opened.

The grating of heavy metal against concrete brings you out of your haze, raspy, like the voice of the person opening the door.

“Do you have any idea how long I’ve been looking for you? I had to ask Dabi if he knew where you were sulking. Are you done being a bi—”

Shigaraki stops mid-sentence, eyes wide. The lewd scene playing out before him robs the words right out of his mouth. It’s not every day you see your half-naked girlfriend getting fucked silly by a nomu, after all.

He stares.

You stare right back, mortification quickly overpowering your arousal.

This interruption goes completely ignored by the nomu, who continues to rut into you from behind.

“Tomura! I can— ah!” You try to come up with an excuse but at that exact moment the nomu gives a particularly rough thrust that has you seeing stars, powerless to keep your eyes from rolling in your head.

Shigaraki curses under his breath, unable to tear his eyes away. He should be angry. Furious, that not only would you fuck someone else but a mindless nomu of all things. The thought alone should have his blood boiling. But the blissed-out look on your face as you’re handled as nothing more than a fucktoy by a creature twice your size has his blood instead rushing to his cock.

Without a word, Shigaraki closes and locks the door behind him, before advancing towards you, face dark and unreadable. He grasps your face in one hand, pinky lifted, squishing your cheeks, and jerking your head up so that you’re forced to look him directly in the eyes.

“You filthy fucking whore,” he laughs, chapped lips spread in a mean grin. “That desperate to be fucked you couldn’t even wait?”

The harsh words have your eyes watering, tears just on the edge of falling, but they do nothing to dampen your arousal.

You moan in reply, eyes half-lidded and unfocused. “T-tomura…”

Shigaraki sneers, letting go of you to reach down and pull out his own half-hard dick, giving his palm a long lick, and begins to stroke himself. “Be careful what you wish for, huh?” he grunts, giving the head a squeeze. “Now look at you. Stuffed with so much cock you don’t even know what to do with all of it.”

He continues to berate you as he jerks himself off, taking delight in your embarrassment.

It’s a relief when the nomu finally cums with a roar, holding your ass right up against its stilled hips. The huge cock twitches and pulses inside of you, unloading what feels like gallons of hot cum right into your womb. You groan out a few unintelligible noises, brain turned to mush, as one last orgasm is pulled from you, thankfully much weaker than the previous ones. You’re so out of it you don’t even notice when Shigaraki steps closer, hand on his dick speeding up until he’s groaning and painting your face with his cum.

Panting heavily, you wearily glance up at Shigaraki, a plea to not share a word of what just happened to anyone already on your tongue. He doesn’t say anything as he tucks himself back into his pants but just by the look in his eyes and the barely concealed smirk, you can tell you’re never going to hear the end of this.
