Yandere Kirishima x Reader - Reprimand

Unfortunately, I’m back! Hopefully I’ll get back into a more regular upload schedule from now on. Anyway, here’s part two to this! I know this isn’t great, but I needed to write something to get myself out of this rut. Also this is sort of a Christmas offering to @ikinabi​, if this pleases you then my life is fulfilled. Also I like yandere Kirishima apparently so I might just make this a series or something. Enjoy! xoxo

(Part 1)

TW: Sorta NSFW, yandere, blood, asphyxiation, physical abuse

“So pretty…” 

Your captor mumbled as calloused fingers combed through your locks. It was therapeutic to Eijirou; to tend to your hair every morning before the hero left for work. You were crushed against his firm torso, ensuring you couldn’t slip from his grasp. Your cries and pleas were met with dismissive hums, as he assured you again and again that ‘There’s no need to be scared, princess’. All he wanted was to take care of you, and for you to just let him. Crimson eyes gleamed with childlike anticipation as he twirled you toward the mirror. “What’dya think, babe? Do you like it?” His voice was dripping with excitement, craving your approval like a coveted drug. His efforts, despite being the product of his drowning adoration, did not produce a… refined result. It was established early during your captivity that submission was met with reward; a kiss to remove that damnable gag, an embrace to rid yourself of the burning ropes around your wrist. So you nodded, slowly and hesitantly as tears trickled down your cheeks. A grin, sharp and beaming, cut across his face. That love-drunk gaze, so maniacal in its infatuation, was enough to chill you to the core. It was a routine Eijirou was adamant on maintaining.

It soon proved to be his mistake. 

You stilled your breath in an attempt to make your fingers do the same. The hair-pin in each hand rattled against the lock. Just like they do in the movies, you told yourself over and over, hoping it would somehow cease the shaking of your fingers. Behind that reinforced window, was freedom. Kirishima was attending some mandatory gala event among his fellow heroes, giving you ample time to enact your escape, and the cover of night would prove useful against the subsequent man-hunt that would surely ensue after he found you missing. The promise of breathing air unpolluted by his musk or the intrusive scent of his cologne was utterly tantalizing. That hope, that dream, was made more tangible with each click and slide of the lock mechanism.

“C’mon…” You muttered, the tension against the pins mounting, threatening to snap as they inched further into the lock. Then, slicing through the silence, an almost deafening creak resounded.

The window didn’t budge. You struggled to breathe as it became clear - footsteps, pounding toward you. Trembling hands released their hold on the hair-pins, falling to the floor. It was hard not to scream in frustration, or breakdown in insurmountable terror. The door inched open, an exasperated sigh escaping your captor as he sauntered in. Each step toward you made you wince as they echoed throughout the room. You suppressed a shriek when strong arms coiled around your torso, his nose pressing against the base of your neck. Kirishima inhaled deeply - he had to get his fill after being apart from you for so long. He hummed, pressing his lips gently upon your skin.

“I missed you so much, princess. I wish you could’ve come with me.” He let out a tired chuckle as his chin rested upon your shoulder. “They don’t think you’re real, would you believe it? Saying shit like if you were really my girlfriend you’d be there with me.” A lingered kiss was placed upon your cheek. “But you are real-” Calloused fingertips explored your arms, shoulders, every piece of exposed skin he could relish in. The sound of his breath hitching, it’s warmth invading the nape of your neck, made your heart pound faster - he was getting excited, that much was certain.

“And you’re all mine.” He traced kisses across your neck, quietly reaffirming ‘mine’ between each affection. Gently, he gripped you by the waist and pulled you toward the bed. Slowly sitting himself upon the mattress, he pulled you atop his strong, muscular thighs. “Isn’t that right, princess?”

You swallowed the lump in your throat, nodding frantically. A deep hum resonated from his chest, digits lovingly raking through your hair.

Oh god, your hair. The accessories he’d so carefully placed were now strewn about the floor. Your thoughts grew panicked, nigh incomprehensible. He could notice, he would piece it together, if he found out he’d surely -

“Come on, (Y/n), talk to me.” His tongue clicked in his mouth, rough fingers gripping your chin and turning you to face him as carefully as he could. Seeing his face, his serene smile, was enough to make the words ball in your throat. Your lips quivered, his eyes beaming as he anticipated the sound of your angelic voice.

“I c-could’ve come with you, I-” A fervent kiss silenced you, his hand cupping your cheek to support the exchange. He pulled away, brows clearly furrowed. With a disheartening sigh, Kirishima shook his head.

“You know I can’t do that, babe.” His lips lunged to your neck, imprinting kisses against the tender flesh. “I want to, I really do. I want to show everyone how lucky I am,” His mouth shifted to your shoulder, your eyes widening as you felt his sharp teeth graze your skin. “I want everyone to know who you belong to.” With animalistic ferocity, he sunk his teeth into your flesh. You whimpered in pain, tears pricking your eyes as you felt blood seep from the wound. Kirishima was eager to lap up the warm substance, working and sucking against the imprint. A powerful arm wrapped around you, keeping you from flinching away as he properly marked you. You opted to squeeze your eyes shut; to pretend you were anywhere but here. A smirk pressed against your skin, a satisfied grunt erupting from the hero at your apparent complacency. “Such a good girl for me.”

His large hand rested against the back of your head, digits entangling with strands of your hair. You felt him pause, and you could swear your heart did the same. Had he noticed? You had to distract him, he couldn’t be allowed find out.

Against your better judgement, you shifted upon his lap until your body faced his. Hesitantly, your hands met his broad chest, inching toward the collar of his dress shirt. His mouth was slightly agape, his pupils dilated with a cocktail of surprise and excitement. Kirishima couldn’t believe what was happening, you were initiating it. Shaky fingers hooked against his tie, slowly working to undo the tight knot. You didn’t dare meet his gaze, terrified of glimpsing at the lust that swirled among the crimson. “B-babe? What are you doing?” His face flared with an impossible red, his pants growing tighter and more uncomfortable with each passing second.

“I-I want to be good for you, Ei-Eijirou.” You cursed at the transparent fraudulence of your words. Kirishima, however, was too euphoric to care. Unsatisfied with the clumsy pace of your digits, he violently yanked his tie away. He made quick work of his shirt buttons, exposing the powerful mass of muscle hidden beneath. His large hands gripped your wrists tightly, guiding your palms against his sculpted torso. He eased them across the rigid canyons of his abdomen, his blush darkening at your touch. 

“S-so strong…” You rest your palms against his defined chest, leaning into the crook of his neck. The scent of his expensive cologne is overbearing as you imprint a fleeting kiss upon his skin. You feel his heart thump, his breath growing more erratic and unrestrained.

“F-fuck, princess,” Eijirou grits his teeth as you gently knead his flesh, throwing his head back to allow you more leeway. “I-It’s all to protect you, so I can keep you safe.” His muscles tense, affirming the immense power they hold. You pause to breathe, to steady yourself. It’s hard not to feel disgusted, not when that prominent protrusion bucks roughly against you.

But Kirishima is impatient. In an instant, you’re thrown unto your back, Eijirou looming over you with your wrists pinned beside your head. Lips smash against your own, his tongue forcing its way into your mouth. He presses his powerful body atop yours, his deep rumbles of delight sending vibrations across your skin. Shark-like teeth sink into your lips, humming as he savors the delectable metallic taste. Your pained whimpers, your weak gasps for air, they’re all so adorable. His fingers intertwine with your locks, pulling slightly to allow his tongue greater dominion over yours.

At first, you’re relieved when he finally pulls away - desperately trying to fulfill the oxygen debt he so eagerly created. But relief melts into abject terror as the muscles of his brow tense, his eyes squinting in scrutiny. Despite the invasive heat of his heavy pants against your face, you’re frozen. 

“Babe…” Kirishima agonizingly pauses. You wanted to break free from his suffocating gaze, but it was futile - every fiber of your being was utterly petrified. “Where’s your..” He glanced back to the window.

You couldn’t hold it back, the tears trailing down your cheeks. He figured it out, didn’t he? 

“Ei-Eijirou it’s not-”

His head snapped back to you. Fury danced upon the rigidity of his features, his breathing labored from barely restrained rage rather than impassioned lust. That voice, often jovial, was seethed through barred teeth. “Did you…?”

You choked on your frantic words, your sobs indicative of your guilt. “I-I’m sorry! I promise, I-I won’t try it ever -”

“Shut up,” Kirishima growls. His grip on your wrists tighten painfully, eliciting a sharp cry. In an instant, he releases his hold on one arm, slamming a balled fist into the bed mere inches away from your head. Your mouth gapes in terror, his knuckles straining threateningly against the skin. The fingers unfurl, instead quickly snaking around your throat in a vice grip. His thumb hardens, pressing against your windpipe with a crushing force. Hot, angry tears trail down his face, his teeth grinding against each other as he spits a stream of muttered vulgarities. You’re gasping; silently pleading for the respite of air, which only spurs his thumb to drive deeper against your throat.

“Why are you making me do this?!” Eijirou squeezed his eyes shut, heart wrenching in his chest. “I don’t want to hurt you. Why can’t you just let me keep you safe? What if you got hurt out there?” Every word threatens to break, his voice unsteady and pained. “Why couldn’t you just behave?!”

Kirishima’s senses regain when he sees your eyelids dipping, releasing his immovable hold. He cups your cheeks with calloused palms, tears mingling with your own as they drip upon your face. Somehow, his softened expression of apprehension is more terrifying than that of rage.

“I’ve been too lenient, haven’t I?” His hand left your cheek, slowly inching down your arm as he shook his head. Eijirou’s fingers interlocked with yours - and they harden. He isn’t choking you anymore, so why can’t you breathe?

“I’m sorry, princess. I don’t want to do this, but what choice do I have?”

You shake your head frantically, your sobs amplifying. He flashes a weak smile, a deranged attempt at reassurance.

“I-I need to punish you, (Y/n). How else are you going to learn?” A brief, apologetic kiss is placed at the corner of your mouth.

The hardened digits crushingly tighten.

“I just want the best for you. You know that, right?”

Tighter

All that work to earn his praise and leniency - gone. That trust you so meticulously earned was crushed, the bones in your hand threatening to do the same. Kirshima shushed your whimpers and cries of pain as he tightened his grip.

“Please, don’t make this harder than it has to be. Take it like a good girl, for me.”

Tighter

Blinding agony, blurred vision, his voice resounding against your ear.

“I love you,”

Tighter

“So never make me do this again.”
