[ 2:15 am, Monday morning ]
He shouldn’t have taken you along. You don’t belong here.
Your quirk isn’t equipped to deal with something like this [ or is it perfect? since all of your senses are acutely attuned to him, your lips open, tongue heavy between your teeth, drool pooling under your jaw and down your neck, your eyes gleaming with an unnatural sheen as you try to hump against his leg like a bitch in heat ] and you have little in the way of melee attacks, or a true defense. No, all you have is your pretty blonde hair, floppy ears that prick each time you hear him, and that incessantly wagging tail that sticks out from your pert little ass, like a goddamn antenna. You’re absolutely too pure for this, too fucking saccharine, and too damn nice to be here.
Fuck. This was a mistake.
[ 72 hours before the mission ]
“It’s in that old warehouse, the one by the docks.”
“Which one? The images that we have show multiple buildings.”
“The fuck do I know? You only wanted me to ask around about the place. If you wanted me to do the damn job for you, you should have said.”
Shigaraki narrows his eyes at Dabi’s hunched back, doing his best to remind himself that they’re already low on funds, on members, and they can’t afford to lose anything else. Not now, when they’re literally scraping along the bottom of the barrel, yanking out whatever dregs they can find and trying desperately to make them stick.
“Did they give you a time?”
“For the exchange? Yeah, said they’re gonna be down there around 1am.”
“And the date?”
“Date?” Dabi questions, whipping his dark head back to Shigaraki’s impassive face, arching one dark brow.
“Yeah,” Shigaraki intones, a half concealed snarl lifting his cracked lips. “The date for when this is all going to take place. We can’t send someone down there every night, hoping it’s the correct time. They’ll be noticed.”
“Said they wanted it to be this Monday, something about shelf life. Apparently this shit is better when it’s fresh. Sells quicker, is more effective.”
“How much did they agree to hand over?”
“Fucking–look man, I didn’t grab a cup of coffee with them, or ask if they wanted to go get some lunch. I told them our terms, they agreed and gave me the location, ‘date’ and time. What did you want me to do? Paint their nails? Suck em’ off? If you’re wanting to get into the drug trade, maybe ask a few more questions yourself. Not leave them to middlemen. You act like you wanna be a leader, so fucking act like–”
A quiet knocking breaks Dabi’s tirade and both men turn toward the closed door.
“What?” Shigaraki snaps, raising a hand to his neck, scritching his long nails against the scars that he finds. It’s a shitty habit, and he knows it gives his agitation away, but he doesn’t care. The sooner Dabi loses his temper and fucks back off to the streets, the better.
The door creaks open and your golden head pops around the corner, hair falling into the empty air as your dog like ears waggle, listening, testing the safety of the room. Your eyes shift from Dabi’s bristled form to Shigaraki and the moment they alight on his stony expression, you smile.
“M-mister Tomura, um, the others… well, we were talking and heard Dabi shouting… uh, they… I mean… I was wondering if you’ve assigned anyone to the new mission? The one you mentioned the other day?”
Dabi snorts and you toss his lanky frame a glare, ears flattening along the side of your head. “Yeah, I bet you wanna know who’s going with Mister Tomura. Got news for you girly, it’s prolly not gonna be you.”
Your quivering pink lips are about to form a retort when Shigaraki’s voice croaks out. “Enough. Tell the others we’ll discuss this later. Dabi, don’t you have some recruits that you’re supposed to show me?”
The flame user waves a lackadaisical hand and stands, inky head cocked toward your pouting face, letting his sharp gaze linger against your angry expression. “Soon boss. Told you already, quality takes time. Not that you know that, since all you seem to attract is freaks, like this one.”
[ 21 hours before the mission ]
“You’re really taking her?” Toga asks, twirling a small knife between her splayed fingers. “I mean, isn’t she kinda lacking in… experience?”
“She’s the only one who can smell out any fakes. I don’t trust these guys. They might try to offload a lower grade product to us.” Shigaraki explains, tucking the battered case of quirk destroying bullets back into his jacket pocket. In the last 24 hours things have gone from bad to worse, what with the news that Twice couldn’t replicate the serum, and the potential, permanent loss of Kurogiri. He’s not about to add double crossed by some two bit drug dealers to that list.
“You want me to give her some weapons? A knife or something? I’ve got plenty of extra. Can’t ever have too many and besides, I like her. And I know she’ll bring them back, safe and sound. She’s such an obedient girl.”
Obedient.
That’s an apt word for you. Maybe it’s an after effect of your quirk, or the puppy-like way you act around him [ with that permanently blissed out smile and thumping tail of yours ] but your swift, unquestioning compliance always makes him think of an over eager pet.
“She’s malleable, and that’s what I need on this mission.”
“Ah! You saying I wouldn’t be?”
“Tch. You wouldn’t even try.”
[ 7 hours before the mission ]
He’s taking you.
It hadn’t been some kind of dream, he’d really shown up in your doorway, with his red eyes glowing in the low light, his sharp jaw tensed, and told you that you’d be accompanying him. Just you and him, together, alone, on a mission where he’d need to rely on you. Could trust you, would talk with you.
As soon as he left, you’d flopped back against the ratty mattress that sat in the middle of your room, trembling fingers already shoving the elastic lining of your shorts down, letting you thumb a quick circle over your throbbing, distended clit. In seconds you’re leaking all over your hand, mind whirring, picturing how he’ll look as he walks beside you, listening for the bite of his voice, imagining him telling you what a good girl you are. He’ll be so pleased, so happy with you. Oh, the things he’ll say to you.
Look at you, you did so well.
Thank you. Thank you for coming on this with me.
I can’t wait to take you [ bend you over and ] with me again.
I can’t wait to [ fuck your little pussy until you’re screaming for me ] get you home safely.
You did such a good job.
I wouldn’t have [ until you’re cumming all over my cock ] been able to do it without you.
You’d make the perfect apprentice, you know?
You really [ such a greedy little bitch ] would.
You’re perfect [ look at how you’re taking me. i’m gonna fuck you stupid, you dirty slut ] and I’m happy that you’re here with me.
That I found you.
Your release builds swiftly. Making your feathery tail ripple over the tattered sheets and your ears tremble in the chilly air. You feel you’re catching alight. It’s too much, and you hate that you’re not taking your time, but you can’t hear his voice as well now.
The memory of it is fading as Mister Tomura pads away from you, down the long hallway that leads to his room.
You remind yourself to listen more, as your fingers pinch and twist at your shuddering clit, to memorize every detail of him. You want to see him every time you close your eyelids and be able to picture him again each morning. To wash yourself in that hazy vermillion of his eyes and the timbre of his voice.
It’s too soon, but your toes are already curling, your back is arching, welcoming the rush of wetness that slips between your shaking thighs. You feel lightheaded, but your dulled senses does nothing to mask the giddiness that keeps bubbling its way out of your chest.
Tomorrow. Mister Tomura is taking you with him tomorrow.
[ Mission begins: 1 am, Monday morning ]
“Um, Mister Tomura… do you want me to go in first? That way you can–”
“No, they know I’m coming.”
“Oooh! So there’s no need for surprise!”
“Correct.”
The dark buildings along the wharf are slowly peeking into view and Shigaraki peers over at your grinning face, his red eyes watchful under the dark hood of his jacket. You look happy, a little too happy. You’re the best choice for this mission, but he can’t shake that uneasy feeling that keeps nagging at the back of his mind.
Eager is one thing, but you’re practically vibrating with excitement. That tail of yours won’t stop lashing back and forth and each time he sees your ears twitch and your head snap up to his, he’s reminded that you’ll need to be looked after on this. Unlike the others, you don’t have an affinity for combat or a quirk that gives you any kind of advantage in a fight. Nevertheless, you’re a member of the league and that connection affords you certain privileges.
Unless he has no other option, he won’t abandon you.
As the two of you step toward the fifth warehouse, you lean closer to him, your shoulder brushing against his obsidian jacket, a quiet huff of air falling from your parted lips. “This is it,” you tell him, mismatched eyes blinking up at his impassive expression.
When he says good, you almost snatch at his arm, and you try to hold back your panting breaths, to not let them slip out, but you know he can see, he can tell. He always can. You feel his sharp gaze passing over you, and sense his blistering annoyance when you subconsciously lean into him a little harder, rubbing your clothed shoulder against his.
“You ready Mister Tomura?” The question leaves you on a whisper and you bite your lower lip into your mouth, wanting him to say yes, wanting him to tell you what a good job you’ve done, finding the location like this. That he’s ready for anything as long as you’re by his side.
“Step back,” he murmurs, lifting three fingers to the door as he shoves it open, the metal wheels screeching into the static quiet of the night.
[ 1:45 am, Monday morning ]
“What’s wrong with her?” Shigaraki demands, releasing the throat of the leader of this de facto gang, sending him crashing across the grimy floor of the warehouse.
“I– koff, koff, I d-don’t… fucking know! She just… shit… sniffed the stuff and started shaking.”
“What’s in it? I’ll give you five seconds.” There’s no time for this and if you’re having some kind of reaction to the drugs, he’s honestly not sure what he’s going to do with you. A villain hospital is out of the question and sensei’s doctor can’t be located. Shit.
“It’s… it’s got some kinda quirk enhancing property… I don’t think that–”
“Five,” Shigaraki begins, stepping over the gristled remains of the others, his red shoes bright against the pools of darkening blood.
“What!? You can’t be serious! Look, man, I’m not the one who manufactured them! I–”
“Four.”
“Oh my God, oh m-my…. look, he said something about increasing the instincts. Making the user less–”
“Three.”
“Libido! It increases libido! I think… no! No! Please! Don’t you–Keep the fuck away from me, you freak! Don’t–I’m trying to tell you! Come on! Please! I don’t–”
Shigaraki lets the man struggle, watching his fruitless scramble across the floor; hands flapping against the gritty concrete with loud smacks, and feet slipping. He looks like a fish on a line.
“None of those things let me know what’s in the drug,” he informs his prey, blood slicked shoes stepping down, trapping the man under his heel, halting his frantic motions.
“That’s not… not… Y-you said you’d give me until five?”
“Did I?” Shigaraki asks, a wide grin cracking over his face, one hand lowering, fingers splayed, reaching. “Looks like I lied.”
The man’s shrieks quickly turn into deep throated garbles as the decay of Shigaraki’s quirk races up his body, reducing him to a mass of shattered bones, hollowed teeth and gushing ichor. Pity, Shigaraki thinks, wiping his bloodied hand against his dark pants and twisting back to your trembling form.
You’re whimpering, your voice catching as you try to gulp down a few breaths and your tail is flat, its usual golden hanging lusterless in the darkness. When he steps closer, your head lifts and he can see the hopeful prick of your floppy ears. Your cheeks and the line of your neck are flushed, creating a burst of dusty pink that blends perfectly with your flaxen hair. You look like a doll, tiny and shivering in the cold, your puppy-like features wilted under the weight of the drug that’s coursing through your bloodstream.
“M-Mister T-T-T-omura,” you whine, one hand lifting, straining for him. “I-I feel… I feel… hot. It… it’s too warm. I think I’m… I don’t know if… if I–”
“Can you walk?” He cuts right to the chase, not liking that shimmering line of desperation that’s laced within your words. You look like you’re about to fall to pieces, but he needs more information. He can’t help you, he reasons, pushing down that inner voice that’s screaming for him to step away from your curled body, if he doesn’t know what’s wrong.
“D-dunno…” you stammer, licking your pastel tongue across your lips, making them slick, pouting them forward. “I don’t… I don’t feel so good.”
“I know,” he reminds you, kneeling in front of you, placing himself within your reach.
In hindsight, it was a stupid move. He knows better. It could have been avoided. He should have paid more attention, not underestimated your tenacity, your want.
Your fingers are under his shirt before he can blink, and before he can breathe, you’re coiling your way into his lap, forcing him to fall to the ground, pressing against him until he’s sure there’s nothing else of you he can hold. “M-Mister… please… p-please! Mister Tomura! Make it go away!”
He tries to shove you off, carefully lifting fingers away, pushing at you with eight digits, hoping you’ll stop squirming. But it doesn’t work and the wet lap of your tongue catches him utterly by surprise. He stiffens under you, his arms falling to his sides, neck rigid, vermillion eyes wide, but you don’t care.
Mister Tomura smells so nice this close.
It’s a musty scent, sticky and clammy, but oh, there’s something else under there. Something that makes you think of slickening skin, the rub of your fingers, and the tacky drip that sometimes falls from between your legs. It’s too much; it’s making you feel woozy and your hands shake as they reach for his face, but you want more. You need more.
“Is this ok? I-Is this alright Mister Tomura? Can I pet you? Please?”
There’s no reply. So you continue, lacing your hands into his pearlescent hair and lowering his lips to yours. He feels rough against your soft lips, so you dip your tongue out to loosen him up, poking until he gives you a halfhearted press, the hot exhale of his nose passing over your pink tinted cheek. “That’s right Mister,” you repeat, encouraging him to let you taste more, rutting your hips against the stiffened plane of his upper thigh. “Let me take care of you, Mister Tomura. Can I be your good girl? Hmm?”
When your fingers pad over his crotch, he groans and his back arches. You pull away, awed by his reaction, hoping he’ll be looking at you, imagining how pretty his eyes will look when they’re lit up with the want of you. But his head is turned and his jaw is set in a foreboding clench. “Mist–Mister Tomura?” you blurt out, hands grabbing at the sides of his face, forcing him back to you.
The dark look he fixes you with makes your heart pound and you can tell your tail is wagging furiously behind you. You like it when he looks at you like that. He likely thinks it’s cold, uncaring, but you know. You know the truth, that he wants you.
Everything inside of you is clattering, rattling at you, screaming out that he wants this.
“I see,” you begin, your hips picking up their pace, hoping he’ll let you slip your rapidly dampening pants off. “You want me too, right? You want me to help you with that.” Here you pause, lowering one hand to trace up the curve of his clothed cock, cupping at it until he’s gritting his teeth, showing you a bright line of white. “I can do that, Mister. I’ll do anything for you, anything. Just let me be your good girl, ‘kay?”
[ 2:24 am, Monday morning ]
He’s pushed you back, but not too far. Not far enough that your delicate toes can’t reach him.
It hadn’t taken much to work his black jeans open, just a quick flick of your wrist and a sharp tug and then there he was, his tip red, beads of pre-cum frothing against his slit, weeping downward. Delicious, is all that you could think, and your lips were around him before he could stutter forward. He makes the cutest sounds when he’s shoving past the ring of your mouth, but it’s gotta hurt his hands when he’s clawing them along the ground like that.
He should relax.
Once you’d worked him over, hungrily slathering over his dripping cock head, and greedily felt him pulse against the flat of your tongue, you’d shifted off of him. He gasped when you let go, and you thoroughly enjoyed the pop that all that wetness made in the still air.
When you slid your pants over the curve of your hips he’d stood, but maybe this drug had given you some kinda super strength besides that fire that was thrumming in your veins, because after you’d trapped him between your spread knees, he hadn’t struggled since.
Maybe he’ll like this? Or this?
It’s really just a guessing game now, and even though Mister Tomura isn’t the most enthusiastic player, he is a reactive one.
The mess of your saliva quickly lubricated the arch of your foot and his copious pre-cum and you run it up and down his straining length, pressing the other forward when you hear him grunting, his hips bucking upwards, helping you.
“You like this Mister Tomura?”
You’re still waiting on your good girl and you hope you’ll do something that ekes it from his clamped lips. But you can wait, after all Mister Tomura likes when you work hard, when you do your best for him.
He lets out a yelp when you speed up and you laugh, so happy that he’s happy.
[ 2:56 am, Monday morning ]
“Mister! Mister Tomura, please! It… ah… it hurts again. C-can you p-put it… mmm… in… inside me?”
It’s the third time you’ve asked him that question, but he’s not listening to you anymore. Instead, he’s shoving you down, lifting the round globes of your red smacked ass and tracing the heavy tip of his cock over your leaking slit. He presses forward and back, slicking himself with your milky release, tacking your arousal all over him. At some point, something broke within him and you’re still exalting in the heady feel of him over you.
“M-Mister Tomu–”
“Shut up. If you call me that one more time, I’ll stop right now. Just leave you here, naked, all alone and unprotected,” Shigaraki threatens, reaching around for your swollen clit and giving it a sharp pinch. You quake under his hands and he watches as your puppy ears fall and your tail brushes against his sweat slicked chest. “Imagine what would happen if someone came along and saw you like this? Saw you panting and humping the floor. You look like a fucking dog. Like some loose bitch who can’t think of anything other than the feel of someone’s dick. You want this? Huh?”
He grabs at your golden hair and pulls you upwards, forcing your spine into a u shape, watching as your tongue flops out of your mouth, as your drool falls down your chest. The tiny buds of your breasts do little to catch the saliva, so most fall on your trembling hands and you let out a piteous whine, hoping he’ll show you some mercy. Hoping he’ll fuck you until you can’t think.
“Answer me.” His voice is iron and you shudder, ass wiggling as you gasp out his name and a chorus of yeses. When his tip aligns with your entrance, it sends a jolt of electricity across your heated skin.
“Want me to call you a good girl?” he asks, pushing until his bulbous head is just tucked inside that first ring of pink muscle, grunting as you try to take him deeper, your cunt ravenously clamping around him.
“Y-yes! C-C-Call m-me that! T-Tell meee!”
“Then promise me you’ll never touch me again. Promise me you’ll never come near me. Tell me I’ll never have to look at that simpering face of yours and I’ll tell you what you want to hear.”
“B-But Mister… I mean… but… T-Tomu-Tomura. I-I can’t do that. I l-love you!”
“That’s too bad,” Shigaraki hums, jerking his hips forward, feeding you another tantalizing inch of his cock, watching as your viscid arousal gushes outward, coating the flesh of your inner thighs and staining his curled thatch of pubic hair.
“Because I don’t love you.”
