Izuku had been on his own a bit too long now. He’d been on a job in your city tracking a trail of criminal activity that had led him straight to you.

Wanted posters with your face plastered on them were hung across the walls of his dark and sad rental studio apartment.

He had maps everywhere with leads and sticky notes. Pins and strings were winding across them all in multicolored webs pointing to spots across the city you’d been linked to.

He knew the danger you posed to him especially.

Your quirk was a mind manipulation type. It made you drive men mad with lust. As far as the hero’s knew, you were able to do this through something like a telekinetic ability but to activate it, your whole body would break out into a blush. That was the only things he’d been told about you, other than that you’ve been using your charms to rob and manipulate people across your large city. No one quite knew the range of your powers, or if someone even looking at you through a screen could be affected.

Cursing under his breath he picked up a photograph of you that one of his informants had been able to get him and looked it over. You might have already been a problem for him even without your power.

He looked around the room at all of the other photos of you he’d gathered over the past couple months. The photos hanging by his bed were zoomed in on different body parts of yours; lips, legs, shoulders, fingers, eyes…one where your plaid yellow skirt had almost blown up in the wind.

He pinned the new photo up on his living room wall and put a new red string across to a second pin to mark on the map of where you were last seen.

You’d been starting to put together a crew of other villains that had quirks that could manipulate people, he needed to move in now before you took your crimes to a more grand scale.

Laying down in his bed he stared at the photos of you so close to him…you were so close to him, and he was so close to finally getting to you.

He imagined every night what it would be like to finally confront you, to finally get his hands on you…

The obsession of catching you had started to transform into an obsession of other sorts, and his hand often found his way underneath his boxers at night staring at photos of you. You were everywhere… everywhere in this city it seemed. Everywhere in his apartment as well, and he needed you everywhere around him.

He’d imagine that with your powers you had to have the sweetest pussy that he’d ever felt. He hated that you were out there using that perfect body to steal from people, making them drool over you with your charms. It wasn’t right. He wanted to, needed to teach you a lesson.

He tucked his favorite knife under his pillow, the metallic red hilt of it poked out slightly from his white pillow.

There were ways to reform a villan. He’d seen it happen. A few of his former classmates had told him how they’d taken some villains underneath them to teach them a lesson. He never thought he’d be one to need to do it; but, for you he’d do anything. You could be good, and you could be his.

———

You were standing in line at a small bank you’d planned on getting a bit of free cash from. Nothing huge so you didn’t bring any of your crew you’d usually keep around with you. This was just for some pocket change for dinner.

You were scoping out the tellers and trying to figure out how to make sure you got the cute older man with glasses at the first desk. He was pretty fit for his age and you wouldn’t have minded taking him out for a spin after you’d gotten some cash out of him.

You let someone go in front of you when the wrong desk opened up next for you. impatiently you hoped that he’d hurry up with the customer he was with. You wore your favorite low cut shirt and short skirt that you liked to have on when you were on a job. It was plain, no grand villain costume for you, just something cute and flirty. Men were easy, even without your quirk. sometimes all it took was shoving your tits forward in their face and they’d give you exactly what you wanted.

Finally the coast was clear for you to head forward. You put on your best flirtatious grin, and felt a small pink blush forming on your cheeks as you started to activate your quirk. that would guarantee you’d be the most appealing woman this guy had ever laid eyes on. At least for while you had your quirk activated he’d think so. He’d have no choice. Even after you’d linger in his mind from time to time if he stared too long at the blush on your cheeks and the way it almost swirled hypnotically under your skin. That was your plan at least. To take all you can but leave nothing but memories of you for their jerk off library.

You barely took one step forward before you were stopped frozen in your tracks. you felt the back of your shirt lift slightly by rough fingertips and something cold and sharp touched the skin of your lower back.

“Tell them never mind, we forgot something in our car.” A quiet voice growled from behind you.

Your jaw hung open slightly. You weren’t sure what to do but every instinct in you that wasn’t keeping your knees from buckling was telling you to listen to the command.

“N-never mind, sorry.” You stuttered speaking to the bank teller then walking out of the line.

The mysterious man behind you still held the blade to your back and walked with you.

“We forgot s-something…” You rushed as fast as you could, trying not to make a scene.

The man walked you to his car, a black SUV, a rental by the looks of it. He shoved you forward against the door face first. Your chest was pressed up against the window and your cheek hit the car hard enough to bruise. He then grabbed your arms, those rough and battered fingers digging sharply into your skin with a power you knew you’d never resist. He put them both behind you and slapped a pair of handcuffs on your wrists.

“You are under arrest for theft, and sexual coercion.” He grunted as he secured the metal handcuffs with a click as they locked into the tightest he could get them without cutting off circulation.

You heard the shuffle of his feet moving against the gravel between your own feet. A knee roughly shoved one of your legs aside. even though you had panties on under your skirt you felt exposed there in the parking lot.

You did a quick glance up to see that it was unfortunately a very empty lot and he had you positioned on the side of the car where any passersby might see.

You felt a nauseating chill -and though it was only because you couldn’t help it- you felt excitement in your core as he started to brush the front of himself against you. He was hard.

You opened your mouth to say something but he suddenly and roughly grabbed you by the shoulders and spun your trembling figure around to face him.

His wavy dark hair fell over angry eyes and a terrifying expression. You recognized him instantly. Though he seemed so much different than you’d seen him on television. Instead of his hero’s outfit, he wore casual loose black jeans and a black hoodie with a black baseball cap, likely to try and disguise his appearance.

Pro hero Deku, one of the strongest heros currently in the game. And supposedly a sweetheart, and good man.

The crazed, widened eyes on face in front of you had you questioning if tabloids had done him wrong. With that knife in hand he looked scarier than most villains you’d worked with in the past.

“I’ve been trying to find you for a long time. You really haven’t been behaving.” He held the knife up to your face, scolding you with it like he was wagging a finger at you.

You felt yourself shudder as your body tried to slump away from the knife the best it could without jerking away from him in a way that might set him off more.

He looked you up and down silently, giving you a terrifyingly casual smirk suddenly before commanding you.

“Now get in the car.” shoving you aside and opening the door you’d been in front of before roughly forcing you in.

He drove you back to a small studio apartment in a part of town you knew well. It wasn’t an area you liked being in. It gave you an uneasy feeling out here. The streets were littered with trash and rats and it felt like there was just a thick layer of smog everywhere more than the rest of the city.

You wondered what a pro hero like him was doing here. Even more strange was why he was even taking you here, instead of a police station.

You gulped nervously. Now that you think of it, you hadn’t heard him call your arrest in to anyone at all. Wasn’t that standard to do?

As if reading your mind he spoke from in the front seat.

“The only one that knows you’re here is me…” A trembling, but excited smirk came across his lips, he seemed like he was starting to sweat slightly.

“Sorry, I’m just so nervous” He chuckled. “I’ve never tried rehabilitation before…so it’s like you’re my first!” he grinned a large smile at you.

You had no idea what he was babbling on about. You were only wondering if when he opened the door you could just use your charms to let you make a run for it.

He stepped out for a moment, gathering a few things from the trunk into a black backpack before putting it on and walking over to your door.

The blush came back to your cheeks and your pupils turned into hearts as you activated your quirk fully.

He swung open the door and you met him with the biggest puppy dog eyes you could muster and a pout on your lips.

“Deku…please, I think I just need to go home.” You flirted. “I can give you something sweet before I go if you want.” You winked at him, with no intention to let him have an inch of your body.

He stalled for a moment, looking you up and down. You bent over slightly so that he could stare down your shirt better. You heard a small sharp intake of breath, and his hands twitched at his sides, like he was resisting the urge to reach out and grab you.

You smirked. They always fall for your charms.

Suddenly, Izuku started breaking out into a crazed laughter, throwing his head back and clutching a hand to his stomach with the hand that clutched the knife tightly still. Your expression fell and your body tensed up, suddenly realizing you weren’t safe from this anymore.

“Honey, that’s not going to work on me.” His eyes met yours. “I’ve been attracted to you. For a while.” He leaned forward down to your level, getting close and dragging the knife across your cheek. The feeling of the cold metal made you tremble.

“I figured the best way to get immune to your charms was no different than building up a tolerance to poison.” He spat out that last word at you, glaring at you as his eyes flicked from yours to your lips and back. He was mere inches away now, and still holding the knife to your skin.

“I’d cum to you every night, sometimes many times a day, just so when I finally got you that you wouldn’t have any affect on me.” The look he gave was unashamed, though what he said had you hanging your jaw open.

He what?

You weren’t blind to the idea that often the men you enchanted would need to go home and take care of themselves later. But, this man you’d never met, this hero no less…thinking of you that way, that often. You gulped and felt it hard to swallow.

He stepped back from the car, grabbing you by your arm and dragging you into the building.

You did try and struggle against him as he pulled you into his apartment, but it was never going to be any use. Your strength matched with his was an absolute joke, and you knew the knife wasn’t the only threat that he had here. Waving around the knife seemed to be more of a show for himself than anything. It didn’t make it less threatening though.

With your hands still behind your back he pushed you forward and you stumbled inside his apartment. He gave you a few more heavy shoves as you clumsily tripped over your own feet and landed stomach down onto his bed.

Your skirt fell up as you landed, your bare ass cheeks now exposed to him on the bed. You heard a sinful and desperate moan from behind you.

You quickly tried to cover yourself back up the best you could, a real blush forming on your cheeks slightly.

Izuku practically growled at seeing the flash of skin you’d accidentally given. He jumped on you and straddled you, sitting on the back of your thighs so that your ass was directly in front of his clothed erection.

You gasped and tried to squirm forward to release yourself from being pinned. Useless and hopeless of course.

This felt so wrong. You weren’t a saint yourself, but this man was supposed to be a top pro hero. A good guy.

You’d seen him on posters and always thought he was such a pretty man. One you’d love to ruin. Of course you’d thought of it. Who doesn’t fantasize about a pro hero from time to time. Not like this though…

Gone was anything resembling a hero. He was just an insane looking man with a knife in his hand and a devilish smirk on his face as he lifted the skirt up further.

“Fuck.” He hissed out. His hands shooting to massage at the plump cheeks. You whimpered out in protest at the feeling.

“Deku…please…what are you doing.” You sputtered your words out against the gray blanket on his bed your face was now buried in.

He grabbed your hair in the back roughly and turned your head so that you got a good visual of what was plastered all over his wall.

You felt cold ice in every limb at the sight. All of the photos of you on display right where he’d been sleeping…every night. You were repulsed and terrified. This wasn’t a normal investigation for him. He wasn’t just tracking down a villain, this had become something more for him. You’d had your own stalker and hadn’t even realized.

It hurt where he was still pulling at your hair. You didn’t dare struggle against him though. With the hand not holding your head down, you knew he still had that knife close and ready to use.

He lowered his face down next to yours, his cheek just ever so slightly brushing against your skin. You flinched away and that seemed to set him off.

“You’re going to have to get used to me little slut.” He then brought his lips to yours and sloppily kissed you. Again you tried to flinch away but he held you right to him in an uncomfortable attack.

You felt his hips starting to press deeply into you and grind against your ass. His hard cock was aching to be set free.

He needed this so badly. He’d been waiting for too long to have you beneath him like this. He told himself this was the perfect time to teach you a lesson. You deserved to be taught a lesson.

He pulled away from you and sat up again to get a good visual of the way he had you in front of him.

“Don’t. Move.” He spoke quietly, but in such a chilling tone that you instantly froze up and obeyed.

He then took the knife and put it to the back of your neck. Slowly he trailed it down, not enough to cut through the fabric of your shirt, but enough for you to feel the tickle of the blade against you.

It sent a shudder across your body and at that your stomach flipped, hoping you hadn’t twitched at all and made him cut you.

“You’re shaking little slut.” He chuckled breathily the knife stalling at your lower back.

His other hand grabbed tight to your hip and he pressed down holding you still to the bed.

“Don’t move.” He repeated hastily and excitedly in a raspy voice.

His hand left your hip and he pulled at your panties.

He took the knife and cut along the fabric of your underwear right over your crotch. You sucked in a tight breath as he was trailing dangerously close from your clit to your asshole. He then set the knife down on the bed next to you. Taking your panties between both hands and ripping it further leaving everything exposed in front of him.

You squirmed harder at this. He gave your ass a hard smack, causing it to redden instantly. You knew how hard he was capable of hitting. the fact that you knew that was probably the most reserved he was capable of being made you feel like death might be easier than what was about to come here.

“Deku…please don’t.” Without many other options to stop this, you tried to turn your quirk on again and woo him into letting you at least have it more gently

Your whole body covered in a slight blush for a moment as you activated it.

To no avail though. Izuku gave your ass an even harder smack. You yelled out at the sharp sting and your eyes squeezed tightly shut. It felt like that one already was developing into a bruise.

You could hear a snicker from behind you.

“It’s not gonna work, naughty girl. Like I said..” he pointed to the pictures of you on the wall.

You looked again through tear blurred eyes again to see the one in particular of your skirt almost flying up.

“I got off to you all the time. I'm immune to your charms.” He started to unbuckle his pants. “At least enough to do this my way.” He grunted as he took his thick and throbbing length out from his pants.

You hoped that the power he extended through the rest of him didn’t reach there, but you knew that’d be reaching for too much luck.

He was huge, and veiny and angry and dead set on being inside of you.

“I am going to teach you what happens to naughty girls like you that whore themselves out to commit crimes. Making good people cum in their pants over you, even if they don’t want to?” He spat at you.

You felt his plump head pressing against your entrance.

He tried to tease you slightly but he saw that you weren’t at all ready for him.

You were going to be reluctant it seemed. But, he didn’t care. He moved back and angrily shoved your legs further apart in one motion, using his knees, and went to enter again. This time with more force, not wanting to have to try again.

“It’s about time you learned what it feels like to be forced to...” he lost his words as he sucked in a sharp breath. The feeling of your walls sucking him inside so tightly had his eyes already rolling back. His lower half shuddered and he realized he was right, you had the most perfect pussy he’d ever been inside.

His hands gripped into your hips so tightly you were scared he’d forget what he was doing and snap you in half.

His head was hung back and he’d stalled for a moment, before starting to move himself slowly.

You hated how he was filling you up so completely. Every time he pushed himself all the way in your body was betraying you with a moan falling out reflexively from your lips.

He seemed pleased at this and continued to give you deep thrusts, his hips pounding against your ass. His breath hitched in his throat when he locked on to the way your ass was jiggling and rippling each time he smacked against it.

“Fuck you’re so good…” he moaned, grabbing the handcuffs by the chain between them. He used the motion to pull you up, making you arch your back and making him slide even deeper inside of you, kissing painfully against your cervix.

You let out a small scream as he started to pound into you roughly like this.

He didn’t seem to mind your protest though. In fact he might have even liked it.

“Guess you don’t make all the men you trick fuck you like this Hm?” He slammed up into you in one rough and painful movement. “Gonna have to show you why it’s a bad idea to go around offering yourself to everyone like a slut.” He grabbed your head again and shoved you back down onto the bed, pressing your face into the blankets but lifting your hips up into doggystyle.

“Please…stop…” you sobbed, hating the filled up feeling of his cock sliding in and out of your walls. He filled you up in a way that was making your pussy throb all over.

You couldn’t help it though. You couldn’t stop your body from enjoying the feeling.

With each unwanted movement, you also were overwhelmed with the reality that he was good with what he was doing. It wasn’t fair.

With no warning the blade of the knife was back against your ass.

You could feel the tip cut slightly against your skin. Not very deep, but enough that you knew he’d broken skin.

“FUCK” you screamed, “What the fuck!”

You heard chuckling from behind you, a raspy and breathy series of laughs. He was so far gone in the moment he might have lost his original plot of trying to rehabilitate you.

He wasn’t sure what lesson he really wanted to teach you at this point. Now that you were here all he really wanted was to never let you leave. Maybe that’s all this ever was about.

You looked so good in person, everything he’d ever dreamed of in a girl. You felt even better. It was just a shame you were a dirty slutty villain. He realized that was the real reason he needed to rehabilitate you.

He’d make you his. His good girl instead of the dirty criminal that you were.

That required a lot of hard lessons though.

“Please…” you sobbed

A trickle of blood ran down your ass cheek from the cut, he wiped it off with the sleeve of his hoodie in awe. he never realized how pretty blood could be until he saw it on you. He’d been around it plenty, but this felt like something else.

To test it he stopped his movements and gave another small cut to the other cheek.

“NO!” You screamed out. He simply smirked at that, letting his thumb run over the cut this time smearing the crimson red across your skin as he picked back up his torturous pace.

The power surging from him being inside you was something you could practically feel. His quirk was something terrifying when he wasn’t being a hero.

It also started to feel like a slight bit of static inside of you along with every pump, he was directing a bit of his power to his entire pelvic area. Whether on purpose or accident you couldn’t tell, but the pace was like nothing you’d ever felt before.

You felt your stomach tightening and you started to clench around his dick.

“Deku…stop…don’t wanna…c-cum” you whined with tears flooding down your face now.

His face lit up at this.

“You’re gonna cum? Shit..” he reached around between your legs and found your clit with two of his fingers. He flicked the swollen area between his middle and index quickly.

“N-no! Please no!” You cried out, though it was useless. His attack on your clit continued, flicking and massaging it with just the right amount of pressure.

It sent you fully over the edge. You shivered as the waves of guilty euphoria were pulsing throughout you. Tears were pouring as well, any makeup you had on was down your face with the wetness as you were sobbing at your body’s betrayal.

Izuku looked down at the way your messy face was pressed ruined against the mattress. All for him. All his now. He’d give you all the lessons you needed. Show you how you’re all his and you don’t need to go around being a slut anymore.

“Tell me this pussy belongs to me now.” He hissed out at you as he was smacking his hips relentlessly against your ass.

“W-wha” you blubbered out.

“You heard me whore.” He grunted as something he did seemed to feel particularly good. “Say it.”

You whimpered, not wanting to give him this, but knowing you didn’t have much choice.

“My pussy is yours now Deku.” You cried out.

He seemed pleased at this, and started fucking into with an even wilder pace. Lots of ‘fuck’s and ‘damn’s were being repeated and you could feel yourself sore with the feeling of his brutal pace.

“Deku it hurtssss” you whined. Something in that seemed to set him off, his eyes widened and he let out an animalistic growl.

“Oh my goddd I can’t keep it in…” he mumbled, slowing his pace and becoming more uneven with his thrusting.

“Gonna cum!” he let out a hoarse cry as he collapsed on top of you, bucking his hips over and over clumsily as he spilled inside of you, letting out a series of ‘oh my god’s.

He pulled out and instantly put himself back inside his pants. You were sat still dripping and full of the cum he’d left there.

“Absolutely disgusting.” He chuckled. “Villains are absolutely disgusting.”

He shook his head at you before shoving you over onto your side.

“I might’ve gotten a bit carried away. But I guess I have to work up more of a resistance to your quirk than I thought. You really do bring out people’s inner animal with that.” He glared at you. “It’s dangerous. Too dangerous even to put you in prison. You’ll just manipulate the guards.”

You now saw that he was moving towards a spot on the bed you hadn’t noticed, a sturdy metal bar with another set of handcuffs on it.

He forced your arm to it and hooked you in to the new handcuffs. Taking the old ones off and tossing them aside.

“I think it’s safer for everyone if you just stay here with me.”

The terror must’ve shown on your face because he gave you a small kiss on your forehead.

“It’s alright. I won’t need to be mean to you once you’re rehabilitated.”

You realized he’d picked the knife back up at some point, as it was being waved around in your face.

He then walked away to his kitchen that was still in the eyeline of his bed, to get himself something to drink.

“I’ll figure out a way to get out of here. you’re no different than me for this Deku” you spat that last bit. “You’re a villain now too.”

He ran back over to you, jumping on the bed in a crouch like an animal and grabbing your face roughly.

“No sweetie, that’s not true. You’re the villain here, and I’m the one teaching you a lesson. Just like it’s always been.” He gave another menacing smirk as he saw you shaking slightly. “Anyways, it’s your fault. You brought it out in me, flaunting it around all over the place.”

You had a feeling you’d flown too close to the sun with your quirk. How could you be so stupid to not realize it would eventually get the wrong hero too riled up.

He had become a feral animal when it came to you.

“So, like you said, you’re mine now.”
