Work Text:

The hotel lobby reeked of manufactured citrus and desperate, low-budget fame. Girls hovered near the velvet ropes, hearts thudding, thighs clenched, hoping to catch even a flicker of those molten red eyes. They didn’t call him King ExplosionHard for nothing, Katsuki Bakugou, TikTok’s most insufferably hot fuckboy, had millions wrapped around his ringed fingers, and he knew it.

Videos of him shirtless, tongue dragging over split knuckles, always paired with some bass-heavy track. Always with that cocky fucking smirk like he already had your taste on his lips. He didn't do dances. He did dominance. Fangs-baring thirst traps. Close-ups of his belt buckle loosening. Comments full of soaked confessions and “ruin me daddy” typed out like prayers.

And tonight was his first fan meet of the year.

He strutted in late, sunglasses still on, phone already recording, streaming for his rabid little following. One by one, he leaned in too close, signed bras instead of posters, growled into girls’ ears till they stuttered and came from proximity. The line got shorter. The crowd got wetter.

And then there was her.

Small hands. Big eyes. Nervous as hell. A green-haired, freckled little thing wrapped in oversized flannel, like someone’s girlfriend dragged to the event. But she was alone. Alone and gorgeous in that dumb, doe-eyed way that made Katsuki's cock twitch behind his jeans. The stream was long shut off.

“Izumi, huh?” he read off her name tag, lips barely brushing her ear. She shivered.

“Y-Yeah.”

“Cute name. You local?”

“No, I- uh, I came down from Musutafu.”

He cocked his head, tongue clicking. “Damn. All that way... just for me?”

Her cheeks flared, and her thighs squeezed together. Her hand went to the lanyard around her neck like she needed something to ground her.

“My boyfriend thinks I’m at a study group.”

Bakugou's grin was slow, feral. “Does your boyfriend make you wet like I do?”

“Wha-?”

He was already gripping her wrist, dragging her past security with a wave. They knew better than to question him when he was like this, on the prowl. That specific kind of look in his eye like he was going to destroy something beautiful.

They barely made it to the elevator. She was already moaning.

 


 

The hotel suite door slammed shut behind them, locking the world out. Katsuki backed her against it with a predatory slowness, his big hand splayed over her hip, thumb grazing the seam of her jeans.

“You nervous, princess?”

“I-I don’t usually-” she started.

He kissed her. Hard. No waiting. No warning. His tongue shoved past her lips like it owned her mouth, his fingers already sliding under her shirt to stroke the small of her back. She gasped into him, melted instantly, and when she felt his cock grind lazily against her belly, fuck, thick, even through the denim, her knees wobbled.

“You got a safe word?” he muttered against her mouth.

“I… yeah. ‘Red.’”

“Good girl.”

He didn’t rush. He peeled her out of those clothes, lips brushing along every inch of revealed skin like she was dessert and he was tasting for sweetness. Her bra unclasped with a flick. Her nipples hardened under his hot breath. But when his hands hooked into her waistband and he dropped to his knees, she froze.

“W-Wait. You’re gonna-”

“Eat your pussy?” he smirked up at her, eyes glowing with wicked hunger. “Fucking right I am.”

“My boyfriend… he says that’s gross. He never-”

He growled. Growled.

“Yeah? Well, your boyfriend’s a fucking idiot.”

She barely managed to whisper his name before he shoved her thighs apart and buried his face between them.

The first lick was slow. Wide. Broad. From her fluttering hole to her clit. She cried out and slapped a hand over her mouth. Katsuki gripped her ass, pulled her closer, grunted against her heat like it made him high.

“Sweet little pussy,” he muttered, already drunk on her slick. “Taste better than any fuckin’ dessert I’ve had.”

His tongue flicked fast now, then slow again, just to keep her off balance. He traced lazy circles around her clit, then sucked it, then teased it with the barest flicks until her legs buckled and he had to hold her up by the thighs.

Izumi moaned, high and helpless.

“Oh my god- fuck, Katsu-”

She’d never been touched like this. Her whole body was thrumming. Her toes curled. Her fingers twisted in his spiky hair, trying to push him away but pulling him deeper all at once. He slid one finger in, then two, curling them up just right while he sucked harder on her clit.

She screamed. No control. Just pleasure cracking her apart at the seams.

“You ever cum from this before, princess?” he rasped, lips slick, chin shiny with her arousal.

“N-No- nobody ever-”

“Then you’re fuckin’ welcome.”

He dove back in. Determined. Devoted. Tongue swirling with obscene skill, matching every moan and twitch of her hips with a shift of pressure. Like he was learning her, syncing to her every nerve ending.

And when she came, she shattered. Full-body quake. Her back slammed into the door. Her hands scrabbled uselessly at the frame. Her voice was hoarse and broken and full of his name, and her thighs clamped hard around his head like she didn’t ever want him to stop.

Katsuki didn’t stop. He licked her through it, then licked more. Addicted now. Groaning like it hurt to pull away.

When he finally stood up, his chin was wet, lips swollen, and his jeans were tenting painfully.

He didn’t even let her stand up straight. As soon as she tried to find her legs, Katsuki scooped her up with those fucking thick arms and tossed her onto the bed like she weighed nothing.

Fwump.

Her back hit the sheets, hair spilling out around her head like a halo, skin flushed, lips parted, thighs glistening. Katsuki stalked over her, eyes blazing like a predator mid-hunt. Every inch of muscle under his shirt was tight, flexing with intent. His cock strained behind denim like it was trying to claw its way out.

He crawled over her, slow and deliberate, hips low, heat radiating between them like a goddamn fever. His lips crashed down on hers again, not messy now, not greedy, but skilled. Precise. Every motion practiced, every tilt of his tongue pulling moans from her lungs and slick from her core. He kissed her like he was memorizing the shape of her mouth. Like he wanted to live there.

His hand snaked between her legs, fingers already soaked from earlier, and he wasted no time. Two thick digits pushed inside, slow but firm, curling up deep and pressing right against that perfect little spot. Izumi arched off the bed, gasping into his mouth, fingers clawing at his biceps.

“O-Oh f-fuck- Katsuki-!”

“That’s it, baby,” he growled against her lips. “You feel that? Right fuckin’ there?”

He pressed again. Rubbed slow circles with his thumb against her clit while his fingers worked inside, stretching her open, teasing her to the brink. Her hips rocked against him desperately, needy, raw. Nothing like she was before. All that shy nervousness was gone. Now she was just drenched and babbling.

“My boyfriend- he never- he just- he never touched me like this-”

Katsuki froze. His fingers still deep inside her, he pulled back just enough to glare down at her, eyes dark and vicious.

“You let some useless fuck stick it in without even makin’ you cum first?”

Izumi whimpered.

“He used to just… I’d suck him off, he’d fuck me real quick, then fall asleep. Said it wasn’t a big deal. Said girls don’t really need it.”

Bakugou clicked his tongue. Shook his head slowly. “Fucking disgraceful.”

He kissed her again, softer this time. A flick of tongue. A drag of teeth. Then he moved down her body, lips ghosting over her collarbone, his voice low and dirty and electric.

“Lemme show you how it’s supposed to be, yeah?”

His mouth found her tits.

First one, he licked the soft curve like he was savoring a rare treat, then latched onto the nipple, sucking it into his hot mouth with a low moan. His tongue lashed it. Swirled around it. Then he grazed it with his teeth just enough to make her twitch.

Izumi cried out, head thrown back, hands flying to his hair again as he switched to the other breast and gave it the same treatment, wet, obscene, appreciative.

He worshipped her like he meant it.

He flicked the tip of his tongue right over the sensitive peak until she was gasping, panting, rubbing against his hand like a needy little mess. His fingers never stopped moving, pressing in and out, stretching her slowly, curling into her G-spot like it owed him money.

“Bet you thought that little quickie shit was normal, huh?” he murmured against her nipple, voice sticky and hot. “Bet you didn’t even know how fuckin’ sensitive you are.”

“I- I didn’t- fuck- I didn’t know it could feel like this-”

“You’re fuckin’ gorgeous like this,” he groaned. “Soaked. Open. Mine for the night.”

Her pussy clenched tight around his fingers when he said that and he chuckled darkly, dragging his tongue back up to her neck, sucking another bruise into the soft skin just under her jaw.

Then, slow and deliberate, he pulled his fingers out and raised them to her mouth. Shiny. Slick. Fucking messy.

“Taste yourself, princess.”

She obeyed like she was born for it, lips parting, tongue flicking out to lick his fingers clean while he watched, hips grinding down against her thigh to ease the throb in his cock.

“Fuck,” he hissed. “I’m gonna ruin you.”

 

His shirt hit the floor with a grunt, and holy fuck, he looked carved from violence and sex, broad shoulders, every inch of him hard muscle and arrogance. Tattoos flexing over his arms, veins bulging down to his wrists, his body was built for fucking and breaking hearts.

Then his belt came undone. Zipper slow. Deliberate.

The moment his cock sprang free, Izumi gasped. Her eyes went wide, pupils dilated like she’d seen god. Or a weapon. Because that’s what it fucking was, a weapon. Ten full inches of thick, veiny cock, flushed red and twitching at the tip, already wet and drooling. Heavy. Proud. Fucking obscene.

“Holy shit-” she breathed.

He smirked, crawling back over her like a predator cornering prey.

“Yeah. Didn’t think I’d be packin’ this much, huh?”

His hips dropped, cock nestling right between her soaked folds, not pressing in yet, just grinding along them. Skin on skin. Vein dragging over her clit. That swollen head catching at her entrance with every slow rock forward. He watched her squirm, felt her hips twitch up toward him, begging without words.

“Fuckin’ wet for it,” he murmured. “So fuckin’ ready.”

He didn’t slide in. Not yet. Just kept rubbing that heavy shaft against her, letting her feel every inch, every goddamn inch, without giving her the relief she needed. Precum smeared slick across her pussy lips, mixing with her arousal, making the grind even dirtier. Wetter. Louder.

Then his mouth was back on her. Sucking hard into the tender spot beneath her ear, hard enough to bruise, to mark. His tongue licked the sting away before his lips dragged down her throat, biting at her collarbone, nipping a path to her tits again. He latched onto one, sucked deep, tongue flicking fast while his cock dragged slow over her clit.

“Hnn- Katsu- please-”

“You beg so fuckin’ pretty,” he growled into her chest, dragging his teeth over the already-sensitive nipple before sucking it back into his mouth. “Bet he never even looked at your tits long enough to get you whining.”

“He didn’t- fuck, he just came and went to sleep-”

Katsuki snarled, lips still locked around her nipple. His hips thrust, not inside, but enough to make that fat cock slap right along her clit, hard and perfect. She screamed, body jerking off the bed like it’d shocked her.

“That’s fuckin’ disrespect,” he growled, voice low and ragged. “This pussy? This body? You should be worshiped. Fucked slow. Fucked deep. Licked till you cry.”

He switched tits, lips swollen, tongue lashing at her nipple like he was trying to taste her heartbeat. His hands gripped her thighs, spread her wider, cock dragging even lower now, the fat tip dipping right to her entrance before pulling back again.

Just a taste. Just a tease. Enough to make her ache.

“Want it?” he whispered, right against her throat.

“Yes, god yes, please, Katsuki-”

“Say it.”

“I want your cock,” she whimpered. “I want it inside- fuck, I need it, please-”

“Say it louder.”

“FUCK ME, KATSUKI!”

He chuckled, dark, filthy, low.

“That’s more like it.”

Katsuki braced himself on one hand, the other wrapped tight around the base of his cock, lining it up with her fluttering, soaked entrance. He watched her face, her jaw slack, chest heaving, pupils blown wide as she felt the weight of him pressing against her hole.

“Gonna go slow,” he muttered, voice gravel, hips nudging forward. “Let that pretty pussy get used to me.”

And he did, oh fuck, he did. The first push was enough to make Izumi moan out loud, the thick head of his cock forcing her open, stretching her with a pressure that was deliciously obscene. Her walls clenched, fluttered, trying to suck him in while she gasped for air.

“Shhh, baby. Breathe. Let me in.”

He kissed her again, softly. Tongue sliding against hers, fingers threading through hers above her head as he eased deeper. One inch. Then another. Her thighs trembled, toes curling, nails dragging along his forearms as he kept sliding inside.

She was soaking wet. Clenching. Fucking tight.

“F-Fuck- you’re big- Katsuki-”

“I know, baby. You’re takin’ it so good. So tight around me, shit, your pussy was made for this cock.”

Halfway in, and she was already moaning broken sounds, eyes rolling as he filled her in ways that stupid boyfriend of hers never could. He bottomed out slow, balls pressed to her ass, hips flush. Her whole body arched, a guttural little cry ripping from her throat.

“There it is,” he groaned. “All fuckin’ in. Feel that? That’s ten fuckin’ inches rearranging your guts.”

He held still for a moment. Let her pulse around him. Her legs wrapped around his waist, trying to pull him deeper, as if her body was already addicted.

Then he started moving.

Slow at first. Deep. Grinding his hips down each time he thrust in, dragging that thick shaft against every sweet spot inside her. His thumb returned to her clit, pressing in little circles, coaxing her higher as he fucked her with deliberate, loving cruelty.

Izumi was gone. Moaning. Writhing. Sweat slicking her skin, eyes unfocused.

Her pussy clung to him like it never wanted to let go.

“I’ve never- fuck, Katsuki- I didn’t know it could feel this good- please-”

“You’re gonna cum on this cock, sweetheart,” he growled into her ear. “You’re gonna soak it, make a mess. And then I’m gonna really fuck you.”

She came. Loud. Wet. Legs locking tight around his back as her whole body shuddered through the climax, nails digging into his skin. He groaned, deep and filthy, feeling her tighten around him like a velvet vice.

“Fuck, baby, just like that-”

He kissed her again, hard. Then pulled out, grabbed her waist, and flipped her over like she weighed nothing.

“Now I’m done bein’ nice.”

He grabbed her hips, yanked her ass up high, pressed his cock back to her dripping hole, and this time, slammed it in. Balls to ass in a single, savage thrust.

Izumi screamed into the pillows, her voice ragged.

“THAT’S it,” he snarled, hips pistoning, hands gripping her waist so hard he’d leave bruises. “That’s what a real man does. Not that weak-ass cum-and-pass-out bullshit.”

Her back arched, tits bouncing with every thrust, her voice a chorus of shameless, sobbing moans.

“Katsuki Katsuki KATSU-!”

“That’s it,” he panted, fucking her harder, faster, the sound of skin slapping filling the room. “Say my fuckin’ name. Forget his. He doesn’t fuckin’ matter.”

He reached down, grabbed her throat, pulled her back against him so her back hit his chest. His cock still buried deep, pounding up into her from below as he whispered against her ear:

“Who’s pussy is this, Izumi?”

“Yours!”

“Say it louder.”

“IT’S YOURS! IT’S YOUR COCK- FUCK- I’M YOURS-”

He groaned, bit her neck, and fucked her so hard the headboard slammed the wall.

Her walls clenched violently around him, a second orgasm already bubbling to the surface, too fast, too hard, overstimulated, body trembling from the brutal rhythm of his thrusts. Katsuki’s pace never slowed. If anything, it got rougher, slamming into her with the full force of his hips, cock battering her insides like he was trying to fuck his name into her cervix.

Her voice was wrecked, nothing but desperate, hiccuping moans.

“Katsu- Katsuki, fuck, gonna cum again-”

“That’s right,” he growled into her ear, breath hot and ragged. “Cum on this fuckin’ cock while I fill you up. You’re gonna take it, Izumi. Gonna take every fuckin’ drop.”

She choked on a sobbing moan, back arching like a bow, and she shattered, again.

This time it hit her hard. Her pussy spasmed around him in desperate little pulses, sucking his cock even deeper. Her thighs trembled. Eyes rolled. And she came so violently she went limp, forehead dropping to the pillow with a broken little cry of his name.

Katsuki lost it.

“FUCK-”

He slammed in once, twice, and then buried himself to the hilt, cock throbbing, twitching deep inside her. His hips jerked. He groaned, loud and filthy, and spilled hot, thick ropes of cum straight into her womb.

It wasn’t one little spurt. It was loads.

The kind that made her eyes flutter from the heat. The kind that dripped out around the base of his cock even while he stayed deep inside. Her pussy was already stuffed, but he didn’t stop. Let it leak. Let it fill her. Let her body know what it was like to be claimed properly.

He kept her folded under him, hips flush, his cock still twitching, throbbing with the aftershocks of release while her cunt milked him for more.

“Fuck,” he groaned, voice raw. “That’s it, princess. All fuckin’ mine now.”

Izumi whimpered beneath him, legs spread, ruined, bred.

He stayed like that, still inside, his palm stroking her back, breath slowing as he leaned down and whispered into her ear:

“You feel full, baby?”

She nodded weakly, voice nearly gone. “S-So full…”

He chuckled, low and smug.

“Good. Gonna keep you like that. Let it stay in. Want you leaking my cum all the way home.”

 


 

Izumi was limp, lying on her back. Her limbs splayed across the bed, her chest still heaving, stuffed and dripping, thighs twitching from overstimulation. Katsuki didn’t pull out right away, savoring that wet, sticky heat. His cock softening inside her, twitching with the aftershocks of orgasm, still nudging her womb, plugging her full.

When he did finally ease out, slow, deliberate, she whimpered.

And then she felt it: his cum spilling down her slit, warm and thick, sliding in lazy rivulets onto the sheets.

“Oh fuck…” she mumbled, shivering. “That’s so much…”

Katsuki slid down the bed without a word. Gripped her thighs. Spread them wide again.

“Wh-What are you-”

She froze.

Because he was looking. Staring. At the mess he’d made inside her. His cum bubbling at her entrance, thick and white, leaking from her swollen pussy. And not with disgust. Not with shame.

With hunger.

“You think I’m gonna let that go to waste?” he muttered, voice hoarse, eyes glowing.

“Katsuki- oh my god- no way-”

But he already had his tongue out.

And when he licked up the mess between her thighs, slow and deliberate, dragging it up her slit and circling her clit, she fucking ascended.

“KATSUKI- fuck-”

He licked again. Deeper. Scooping his own cum from her still-quivering hole with his tongue and moaning at the taste like she was ambrosia. He gripped her hips, holding her down as she squirmed, overwhelmed, tears pricking at her eyes from overstimulation and shock.

She couldn’t breathe. Couldn’t think. Her mind short-circuited.

Because her boyfriend- he wouldn’t even kiss her after she went down on him. Would roll over, leave her wet and aching while he snored.

But this? Katsuki?

He was tongue-deep in her pussy, licking out his own cum like it was whipped cream off a spoon. No hesitation. No shame. Just groaning like he needed to taste her mixed with him. Like he wanted to own her from the inside out.

“Your boyfriend’s a fuckin’ idiot,” he growled into her heat, sucking her clit back into his mouth while his tongue swept through the slick mess. “You taste like a goddamn drug.”

Izumi was shaking now. Moaning helplessly, toes curled, face flushed and blotchy from overstimulation, but he didn’t stop. He pushed two fingers back inside her, massaging the cum deeper, working her open while his mouth ravaged her clit.

She sobbed. Back arching. Every nerve raw.

“Katsu- Katsuki please- I can’t- I’m gonna cum again, fuck I’m gonna-”

He grinned against her pussy. Sucked harder.

And she came again, sobbing. Her whole body locking, pussy clenching around nothing, slick and cum squirting into his mouth as she broke apart completely.

Katsuki didn’t stop. He ate it all. Swallowed her moans. Swallowed his cum. Swallowed every last trace of her shame, her hesitation, her memory of anyone else before him.

When he finally came up for air, chin soaked, hair wild, eyes glowing with victory, he looked down at her limp, twitching, cum-leaking body and smirked.

“Now that’s how you treat a pussy.”
