Hey do you think you can write about kirishima and his darling from bitter work? I’m curious about them

W/C: 800+

A/N: Made this a self-insert for readers despite it being a spin-off.

You keep your hand over your mouth to continue to suppress your noises. This wasn’t the first time and it certainly wouldn’t be the last, you weren’t even sure what to feel anymore. Ever since the first time Kirishima forced himself on you, you would always freeze stiff in fear, he kidnapped you and ranks quite high within the pro heroes, you didn’t know what he was capable of, so you simply settled for not doing anything.

Your silence and lack of movement convinced him that you were simply shy in sexual situations, as well as nearly everything else given how little you spoke. The first few times, your mind was too filled with fear and anger at feeling so vulnerable and unable to do anything, because in truth, what could you do? The fear occupied your mind enough to keep you from feeling anything, but as time progressed and he continued to have the same sexual activities with you, you slowly started to grow accustomed to them.

After a while, there was always some reassurance that he never hurt you with anything other than penetration, never hit you, grabbed onto you too hard or verbally abused you. As the fear of your pain increasing dissipated, you were left with nothing to distract you from his movements against your body as well as being unable to deny yourself that he knew what he was doing, he knew exactly how to treat your body to give you immense pleasure. Pleasure that you didn’t want.

A tear manages to leak through your squeezed-shut eyes as you remain on your side, facing toward the blank tv with Kirishima behind you, spooning you with an arm over your waist to keep you against him while thrusting into you at a steady pace on the living room couch. Your eyes roll to the back of your head with your lips parting to let out a muted moan at the next orgasm he forces out of you, your body finding undeniable pleasure in him.

Following your release, you hear the familiar groan coming from behind you before feeling your insides quickly flood in his thick cum as his body relaxes against your trembling frame. You feel him smile as he traces kisses along your shoulder up the side of your neck with your eyes squeezing tighter. “You serious? I sleep on that couch.” You hear another thick voice speak, having your eyes widen.

“Sorry Bakugou, we didn’t make it to the bed.” Your kidnapper apologizes without looking at him or even growing concerned enough to cover your naked body, continuing to smile against your skin instead. Bakugou grunts in return and leaves to his room upstairs, wanting to rest after his hero work, ignoring the look of terror in your eyes.

“I’ll be home soon, okay?” Kirishima assures, cupping your face in his hands while you stare down with slightly wide eyes, always stuck in between your fight or flight instinct whenever he touched you. He moves to press a kiss to your lips to which you subconsciously move back from where you’re standing with him at the doorway. “Aw, there’s no need to be shy.” He looks at you lovingly, obvious to your true feelings.

“They’re not shy, dumbass.” Bakugou says from his spot on the same couch you fucked in earlier without taking his eyes off from his phone, being aware of Kirishima's delusional personality. “What are you talking about?” Kirishima innocently asks after a questioning hum. “Just go to work!” He nearly shouts, still refusing to remove his eyes from the screen. “I love you.” Kirishima’s lips successfully capture yours in his, saying his last goodbye’s before finally leaving for his night shift.

You slowly turn to look through your peripherals and see Bakugou staring longingly at the picture of someone you don’t recognize. The almost sad look on his face quickly disappears with him looking over at you with a scowl, making you quickly look back down and rush up the stairs to your ‘room’.

~.~

After hours of trying to fall asleep, you finally feel your eyes starting to give up on you, feeling half asleep how your body is succumbing to exhaustion despite the fear of your captor’s roommate. You miss the sound of the door opening followed by the quiet footsteps towards the large bed where you lay, a few silent thumps of clothes falling on the floor before the feeling of the space behind you dipping completely wakes you.

A pair of soft lips press behind your ear in a kiss with a familiar set of razor sharp teeth gently biting after, a tongue running over the skin while you take notice of the grinding of the stiff length between your ass cheeks, the tip managing to slip under your shirt to drip its precum on your lower back, warning you of a long night.

Bakugou Katsuki:

Blood poured from your lip and dribbled down your chin. Your jaw ached and your ribs whined with each of your movements as you pushed open the front door, almost collapsing just as you made it inside. 

“YN?” Bakugou’s angered voice thundered from the kitchen. “Where the hell have you been?”

Even speaking was too much effort as your mind fogged, forcing you to slump into the nearest chair. The sofa felt so… so soft. 

Maybe a small nap wouldn’t hurt. 

“YN?” Loud thumps came closer and closer before a blurred form stood in the entryway of the living room. “YN!”

“Katsuki…” You struggled to keep conscious, head lolling to the side every few seconds as Bakugou’s eyes widened. 

Your state was horrific. Body littered in bruises, he couldn’t tell exactly what blood spatters came from where. You looked like you were dead on your feet. “No, no, no! Who did this?”

His teeth grinded as he struggled to caress your cheek as tenderly as possible. Hot, fiery rage lit up the pit of his stomach, almost travelling to his hands before he stopped himself from exploding just next to your face. 

“I’m…” you could barely keep your eyes open, “...so tired. I wanna take a nap.”

“No, YN, stay with me! You’re gonna be fine!” Crimson eyes were aflame with a worry you’d never seen before mixed in with the normal fury you were used to. “I’ll kill whoever did this to you! I swear!”

Bakugou could only watch as you finally gave into exhaustion, head dropping back onto the top of the sofa before your body relaxed completely. 

Angry. Angry at you for getting into this mess. Angry at the man who thought he could live after doing such a thing. And angry at himself for never trusting his gut and locking you away for good. 

Pressing a shaky kiss to your cheek, Bakugou rose from his crouch at your side and glanced toward the door. He knew what he had to do. 

The next day, you were in the hospital being treated for your wounds. Of course, they asked what happened and who did this to you, even daring to flash Bakugou a suspicious look as he stood at your side with a glare. 

There was no point in looking for the man who hurt you. He was gone. His body--or, rather what remained--was littered around the nearby forest, already being feasted upon by local wildlife. The charred bits of his existence served as a reminder that Bakugou never turned down a fight when it came to you. 

Because no one touched you and got away with it. No one.

Todoroki Shouto:

He can only watch, shell-shocked, as you stumbled into the house, leg limping and cheek a dark purple. 

“YN.” In an instant, he’s on his feet, right hand stretching out to soothe your bruise. A sigh leaves you at the feeling of cold on your burning cheek, leaning more into your boyfriend’s hold as he directs you to the couch. 

After five minutes of him checking every inch of your body for more damage, he finally leaves and returns with a cup of steaming something. 

“Drink this,” he mumbles, concerned eyes watching your every move as you gulp down the tea. 

When you set down the mug, he returns his hand to your face, running his fingers over the marking that has finally stopped swelling. 

Todoroki struggles to meet your gaze as he runs his other hand along your thigh down to your wounded knee. “Who… who did this to you?”

“It’s just part of the job, Shouto-”

“No,” he grits out, setting both hands on your cheeks to keep you facing him. “Who did this to you? Where is he?”

“The cops already arrested him, Shouto.” You reach a hand up to grasp his wrist, running a thumb along the skin. A smile works its way onto your face. “Trust me, I gave more than I got.”

A muscle twitches in his jaw before he finally nods, pulling away and standing up. “Okay. Fine. I’ll let it go. But please be more careful next time.”

Tension leaves your body at his willingness to give in and the grin on your face grows. “I will. Now what’s for dinner?”

That night, Todoroki lies on his back and stares at the ceiling, too uneasy to sleep even with you curled into his side. The cops have him. He’s detained.

But he hurt her.

Somebody hurt the love of his life and got away with it. Not for long. 

Ever so slowly, he slipped away from your hold and left his pillow in his place, stopping in his tracks just for a second to watch as you hugged the pillow tighter to your chest. 

Somebody hurt you, YN. Surely you know I can’t let him get away with that. 

Getting into the precinct was easy, but it was even easier to bribe the cops to let him see the arrests of the night. Specifically ones with bruised fists. 

“Sir, we can’t just let you-” Todoroki flashed his gaze to the fumbling cop. 

“How much?”

“W-what?”

“Give this guy to me,” he nodded toward the criminal cowering in the corner of the cell, “and you could be set for life.”

“Sir…”

The deal was made and the cop turned a blind eye as Todoroki walked out with a more-than reluctant criminal in his grasp. 

“Please, I’m sorry! I screwed up! Just take me back! Please!”

The whining never bothered Todoroki; instead, he was annoyed at just how loud it got as soon as his punishment was dealt. 

It became a question of whether the man died of burns or frostbite--either way, Todoroki knew the man was feast for the fishes as he dropped the charred remains off the bridge and into the river below. 

When he finally returned home, you didn’t even stir once as he showered off the scumbag’s touch and returned to his place in your arms with dripping hair. 

“Shouto…?”

“Shh, go back to sleep, YN.” And you did, ever so safe with Todoroki at your side. 

Because with him, nobody would dare to hurt you again. 

Kirishima Eijiro:

The second you walk through the door, Kirishima’s at your side, ushering you into the bathroom. With a washcloth, he wipes the dirt from your face and neck, stopping every few seconds to stare at the finger-shaped bruises on the skin. 

You knew it the instant you looked into his eyes. “Eijiro… don’t. You know it wasn’t your fault.” 

Guilt covered his face like a veil, draping over his entire body until it appeared as though he had let the world down in some way. 

“I should have been there, YN.” His teeth grit in frustration and his hands ball up into fists. “I should have kept you safe.”

“You can’t be there every second of every day, Eijiro.” You place a hand over his and caress the skin. “I don’t blame you for this. It wasn’t your fault.”

He shakes his head. “You’re wrong, YN. I should have been there. It’s my responsibility to keep you safe.”

Your heart warmed at his declaration. He was always so kind, but sometimes it was a pain that he would take on so much in your stead. 

“I could have protected you…”

No words you could say could bring him out of this now. All you could do was stay by his side to ensure that you were still alive and safe until he got over his guilt. 

“Let’s go.” You stood with a small smile, offering a hand to him.

Hesitantly, he accepted the offer and rose to his feet, confusion taking over his features.

“What are we doing?”

“Let’s spend the day together, inside. Just the two of us. No distractions. No outside world. Just me and you.”

The thought lit up his face in an instant and before you knew it, you were being lifted into his arms and hauled out to the kitchen. “All right, but only if you let me do all the work. You just sit and rest.”

That night, Kirishima stroked the skin of your cheek, grinning as you slept so peacefully in his arms. You were safe. You were okay. You were with him. 

He wanted you like this forever. 

Forever. That could work. The window just behind your back would need to be locked and blacked out so nobody could see you inside. The doors would need to be chained and bolted with keys only Kirishima had so he could make sure you were in his presence. No leaving without him. No going out without him at your side. Nothing.

You would be safe and in his arms forever. How… perfect.

Kirishima hummed blissfully at the thought. If today said anything about how you felt, then surely you would agree to this too. 

With this plan, you and Kirishima could be by one another’s sides forever, safe and in love. 

Just perfect.
