Summary: Your neighbors are acting rather obnoxiously, so you decide to have a word with them. (short fem!reader with a super strength Quirk)

Warnings: NSFW, vaginal fingering, light bondage, some cursing, and definitely some sweet talking

Enough was enough. You had tried to be patient with them, but there was only so much that you could take, especially when your walls were currently rattling so hard that all of your hanging picture frames and decorations had fallen off of them. You didn't know why your neighbors were blaring their music so loudly, but it was about time for them to stop. You and Sero had a charity event to attend after he got home from patrolling, and you really didn't need that kind of background music distracting you while you were getting ready.

As the saying goes, you catch more flies with honey than vinegar, so in what was supposed to be a gesture of goodwill towards your neighbors, you filled up a cookie tin with some treats that you had made earlier. After that, you then made your way over to the apartment that was adjacent to yours, whose door was still somehow miraculously hanging on even though it looked like it was literally vibrating because of the loud music playing behind it. With a deep, calming breath to help you center yourself, you plastered the sweetest grin that you could across your face and then rapped your knuckles against the door.

Based on the way that the music didn't stop, you assumed that they hadn't heard you, so you knocked again, slightly harder this time. Still no reply or pause in the music. You had to knock five more times before the music finally lowered (although it wasn't by much), and, seeing as you kept increasing your strength with each consecutive knock, there were now some nice knuckle-shaped dents on the front of the door. Your levels of irritation had increased dramatically in the minutes that it took you to get your neighbors' attention, but you still kept the smile on your face, knowing that Sero would have wanted you to keep this civil.

Of course, when your scowling neighbors finally showed up at the door, yanking it open with a fury that you knew was unjustified, you realized that civility might not be have been on option in the first place.

"What the hell do you want?"

You hadn't seen your neighbors much beforehand; they were relatively new to the apartment complex, and you could see now that they were a relatively young couple, probably about the same age as you and Sero. Maybe in another life you could have been friends with them, but as it was currently, they were going to be lucky if they didn't end up getting the same treatment as their door.

"Hi! I don't think we've met yet, but I'm your next-door neighbor! It's nice to finally meet you, and I brought you some treats as a welcoming gift!"

It physically pained you to keep your voice so steady while you greeted them, but you were hoping that the sight of a small, gentle-spoken woman would make them lighten up a bit. It didn't.

"Right, whatever. Are you just here to fuck around or do you actually have something important to say?"

Maybe if rage hadn't been boiling through your veins, you would have noticed your grip on the cookie tin tightening, but that was obviously not the case as your smile took on a much more manic quality.

"Well, actually, your music is a little loud, and I was wondering if you could turn it down a bit."

Obviously, your neighbors didn't hear the sound of bending metal, either.

"Fat chance of that, Shortstack. Leave us the hell alone."

They slammed the door right in your face, which was definitely not a good idea considering that it was the final straw that made you drop all sense of propriety. The next thing that your neighbors knew, their door had been ripped right off of its hinges and there was crushed cookie tin whirling its way into their apartment. They both paled as they looked back to where the door should have been, your tiny form looking much more terrifying than it had earlier, the chilling look on your face enough to let them know that they should have acted just a bit more politely.

"I'm gonna need you to turn that shit off."

When they didn't move (which, in hindsight, was probably because they were terrified), you decided to help them out by ridding them of whatever music system that they had. However, as you stepped foot into their apartment, a familiar set of arms wrapped themselves around your waist, and you felt yourself being lifted up before you were carried away from the scene.

"Sorry about that! I'll take care of the door later!"

"Damn it, Hanta! Let me at those rude fuckers!"

He did not let you at those rude fuckers, unfortunately, and before you could try to convince him to let you go, he had you back inside your own apartment. He stood between you and the door in an effort to make sure that you didn't go back to the other apartment.

"Y/N…"

The way that he breathed your name, coupled with the soft grin that he gave you, made you turn your head away in embarrassment as a light blush crossed your cheeks. It was an unfair power that he had over you, that gorgeous smile of his able to quell your anger within seconds. It made you embarrassed over how quickly you had lost your temper, and while you would admit that ripping a door off its hinges may have been a bit of an overreaction, those jerks really did deserve to have some fear put in them.

He didn't seem to blame you, though, and that smile of his never left as he leaned down to press his face against your neck. His hands also went to rest on your hips, and the apartment was quiet as Sero took a moment to breathe in your scent before placing a light kiss at the juncture of your neck and shoulder.

"I won't lie, I kind of figured this would happen. I ran into them a few weeks ago, and I just knew it was only a matter of time before their attitudes got them in trouble with you. I didn't expect you to tear their door down, though."

"Hmph."

"Aw, are you still mad, Y/N?"

"A little."

"Mm, that's alright."

Sero followed his statement with a few more hot kisses to your neck, lingering with them for a moment to make sure that they gave you chills. His hands also started to wonder, moving to caress your thighs as they were exposed by the dress that you were wearing.

"We can't have you mad while you're at the charity, now can we? I guess I'll have to take care of you."

He briefly pulled away from you to check the time on his phone, making a disappointed 'tsk' when he saw how late it was.

"Hm, we don't have a lot of time, though…Well, I can work with it."

Before you could question what he was talking about, Sero dipped back down, this time pressing his lips against your own. It was such a gentle kiss, but it was still enough to keep you distracted as Sero took both of your arms, holding them above your head and spinning you around until you were pressed against the wall. His hold on you momentarily disappeared, but then you heard the ripping of tape, and as Sero finally ended the tender kiss, he taped your hands against the wall.

"Keep these here for me, alright?"

You couldn't even properly reply to him before his lips were working against yours again, still gentle in their movements, matching perfectly to the light trailing of his fingers against your inner thigh. That tender touch climbed higher and higher, until Sero's hand finally reached your clothed mound and he stroked you along the outside of your underwear.

"You shouldn't let people like that get to you, you know?"

As Sero slid his hand into your panties, he moved his head back to your shoulder, leaning it there and turning his face towards your neck so that you could practically feel his words against your skin. He teased you for a moment, barely tracing his fingers against your outer labia as you tensed up with anticipation.

"They don't deserve your time or effort."

He finally pressed further into you, humming at the warm slickness that his fingers met before he continued to caress your womanhood.

"Hanta, please just-"

"Shhh. I told you that I'd take care of you, right? Just be a little patient."

His touch against you was soothing in nature, but it did little to actually calm you. You needed more from him, and you tried to buck your hips against his hand to get the friction that you craved, but you could only move so far since you were pinned against the wall. You could feel his smile get bigger against your neck, and he finally brought his fingers up to your clit, lightly circling them over the engorged bud and causing you to gasp.

"See? All you had to do was trust me."

You almost groaned when he took his fingers away from you, but before you could get the noise out, he was sliding two of his long digits into your waiting entrance, his thumb moving to press against your clit. You did end up groaning after that, but it was sound of relief instead of frustration.

"You're so amazing, Y/N. You have so much strength hidden in that beautiful body of yours, and it never fails to amaze me."

You couldn't reply to him, not through the moan that you let out when he started to pump his fingers in and out of you, ever so slightly curling them forward so they could pass over that sweet spot inside of you. He was also putting his thumb to work, slowly working it around your clit as your legs started to tremble from all of the stimulation.

"I feel so lucky to have you, to see you smile every day, to kiss you, to touch you, to make you feel this good."

His words only fueled the fire that was growing in your belly, and your body grew taut as your climax crept closer and closer to fruition. You couldn't help but chant his name like a prayer as he continued to work you, the last verse being shouted as your orgasm burned through your body. Your hips stuttered against your lover's hand, and he pulled it away from you as you started to whimper from his overbearing touch, settling to just stroke your outer folds again as you finally started to relax. Once your breathing evened out, he pulled his hand away from you completely, and moved to where he was leaning his forehead against yours.

"Better?"

"Mhm."

"That's good. We still have a few minutes to clean up before we have to head out, if you still want to go."

"Kind of hard to skip out on a charity. I just need a minute. And Hanta?"

"Hm?"

"Thanks."

"Any time, babe."
