Flashbang

Summary:

Inspired by Devil's Price by whisper2025. Thugs capture Daredevil and try to sell the unmasking to Frank Castle. But instead of waiting patiently for the Punisher to arrive they take advantage of the chained Devil of Hell's Kitchen.

First chapter noncon + rescue oneshot if that's the only part you want to read. Second/third chapters for aftermath/recovery.

Consensual Fratt starts in forth chapter. Additional chapters are entirely Fratt sex-as-a-coping-mechanism smut. Time skips in between with smut-focus. I won’t be exploring a romantic relationship aspect. Starts leaning harder into BDSM around chapter 10. SSC/RACK language, but they're both coming into this with significant prior experience with BDSM so if you're looking for them to be learning about it together, this isn't it.

I won’t mark it as complete since I'll be adding more as I think of something I want them to explore.

Notes:

i was going to leave it at this but setting it at 1/? for potential aftermath and recovery, maybe Fratt as part of it. just sorta grew more than i thought it would. i'll add tags for whatever i add but you could probably treat it like 1/1 for now.

Chapter 1: (noncon/rescue)

Chapter Text

     Matt had tracked a new drug to a warehouse where he could hear four agitated men packing the product. Through their nervous chatter, he picked out two of their names. Leo, wiry and jumpy, was the anxious planner. Vinny, heavier and aggressive, was the blustering muscle. Two other thugs provided distracted, clumsy manpower. A fifth man waited in a side office. He had the calm and professional heartbeat that marked a serious complication.

     Matt neutralized the four amateurs quickly, but the Pro had anticipated him, using a net launcher and a flashbang to overwhelm his senses. Beaten and with a shallow knife wound in his side, Matt was dragged to a support beam, as he spared a thought regretting that he had come out in his black gear tonight instead of his red suit.

     He was forced to his knees then slammed face-first against the cold steel of the support beam. His arms were wrenched up above his head as a heavy chain was looped tightly around his wrists and then around the beam itself, secured with a padlock.

     His left ankle was yanked back and chained to a solid iron ring set directly into the concrete floor. The same was done to his right, splaying his legs apart in a wide, immovable stance.

     He was completely secured, every point of tension locked down. He could only shift minutely, but leaning back to balance his weight onto his spread knees strained the searing knife wound in his side. Leaning forward to relieve the wound made him precariously unbalanced, putting all the stress on his wrists and shoulders.

     As his hearing painfully recalibrated through the taste of blood and the throb of his wounds, he listened to them argue over what to do with him. It was Leo, cradling his broken wrist, who proposed the desperate scheme. To sell the captured Daredevil to the one man who would pay anything to unmask and kill him... Frank Castle, the Punisher. Over the Pro’s silent disapproval, a call was made to a mercenary bar, and the offer was sent.

     Now they waited. Leo paced, Vinny watched Matt with greedy eyes, and the Pro cleaned his gun. Matt focused on the chill of the concrete and the bite of his restraints. They hadn’t called for a buyer. They’d summoned a hurricane, and his only goal was to survive it.

     The waiting stretched, filled only by the rhythmic click of the Pro cleaning his gun and the drip of a distant pipe. Then a new sound cut through. A low, wet sniff, followed by a shifting of heavy boots on concrete. One of the muscle thugs, the bigger one, had taken a few steps closer. Matt could smell the cheap beer and nervous sweat. And underneath it… the thick, pungent scent of arousal.

     A pit of cold dread settled in Matt's stomach.

     "Hey, Leo," the thug rumbled, his voice thick. "We got time to kill. He ain't going nowhere. Any rules against… using the merchandise while we wait?"

     The implication hung in the air, ugly and clear. For a second, there was only the drip of the pipe. Then Matt caught the scent of excitement from the others. From Vinny, a greedy, vicarious thrill. From the other muscle, a furtive curiosity. Even from Leo, a spike of vicious, approving interest. The Pro huffed in annoyance, but the heat radiating off of him betrayed his interest.

     "Rules?" Leo laughed, the sound brittle and high. "We make the rules now, Brick. Knock yourself out."

     Brick walked over to a cluttered toolbox and began rifling through it. He pulled out a heavy steel o-ring, the metal dull and cold. "Tiny, grab something to tie this with." He said to the Other Muscle.

     Tiny moved quickly. He snatched a coil of nylon rope, cut off two strands about the length of his forearm, and knotted the ends securely to the o-ring. Matt felt his heart skip as he recognized it as a crude ring gag.

     "Alright, Daredevil. Let's see that mouth," Brick sneered, turning back to Matt. As Brick tried to shove the o-ring between his lips, Matt strained against every chain, ignoring the protest from his injuries. He clamped his jaw shut, his head twisting away. When Brick's thick fingers pried at his lips, Matt bit down hard, tasting blood and salt.

     Brick roared, yanking his hand back. His other fist drove into Matt's temple. The world dissolved into a fresh wave of static and fuzz, the lingering pain from the flashbang roaring back to life and disorienting him. Through the fog, he felt hands on his face. Tiny's fingers, strong and insistent, pried his jaw open.

     The cold, hard circumference of the steel ring was forced into his mouth. Brick held it there while Tiny worked quickly. The two nylon straps were drawn tight behind Matt's head and knotted securely. The metal pressed cruelly into the tender flesh behind his teeth. The nylon ropes dug into the corners of his mouth and the skin of his cheeks, pulled taut enough to chafe with every strained breath.

     Through the ringing haze in his head, Matt heard Brick’s voice. “I’m going first.” His words were thick with anticipation.

     “Like hell you are,” Vinny cut in, his voice a pained wheeze. “My kneecap’s in my damn chest. I got the worst injury here. I get to go first. Drag that chair over.”

     There was a scraping sound as a chair was pulled across the concrete. Matt heard Vinny’s labored breathing and the uneven thump of his limp as he approached. The sour smell of his sweat and cheap cologne washed over Matt a moment before a hand fisted roughly in the back of his mask, right at the knot that secured it.

     Vinny yanked his head back, forcing Matt’s face upward. “Look at you,” he sneered, his breath hot against Matt’s cheek. “The big, bad Devil of Hell’s Kitchen. Not so scary now, are you? Just a guy in a stupid mask.” He gave the fabric another vicious tug, the pressure sharp against Matt’s skull. “You hear me? You’re just a guy.”

     Matt choked as Vinny shoved into his mouth without further preamble. It was a disjointed violation of sound, smell, and sensation. Vinny’s grunts were loud in Matt’s ear, his breathing ragged and pained from his own injury. The chemical reek of cologne mixed with the sour stench of unwashed skin and beer sweat, a nauseating cloud that filled Matt’s nostrils. Every clumsy, groping touch was an electric jolt of revulsion, a frantic signal his trapped body could not answer.

     His mind retreated as his mouth was used. He focused on the distant drip of the pipe, the groan of the warehouse’s old bones, the cold bite of the steel in his mouth. He parsed the other heartbeats in the room, Leo’s excited flutter, Brick’s impatient thrum, the Pro’s steady, detached rhythm.

     But each time Vinny thrust fully in, his cock brushed the back of Matt’s throat, making him gag and pulling him back from his retreat. Each time his nose was pressed flush with Vinny’s greasy pubic hair, he struggled to breathe. 

     The only, bitter solace was that it was over quickly. Vinny’s movements grew frantic, his rhythm faltering, and he pulled out and finished with a sharp, choked gasp. Hot, wet stickiness spattered across Matt’s cheek and the lower half of his mask.

     A fresh, deeper wave of disgust rolled through him. It wasn’t just the violation of the act, but the lingering, physical claim of it. He would reek of this man for days. No amount of scalding water or harsh soap would scrub the memory of this smell from his skin.

     He felt Vinny scoop some of the mess off his face and rub it into his mask, smearing the mess deeper into the black cotton. The mask, his symbol, his shield, was now fouled, defaced in the most intimate and demeaning way possible. He would have to burn it. He would never wear this one again.

     Matt winced as Vinny pushed the chair back, the legs screeching on the concrete. He slowly stood and limped away, his breathing heavy. “Pathetic,” he spat, though the word seemed aimed more at himself. “Brick. He’s all yours.”

     Brick circled him like a predator, kicking the chair away to loom over Matt. The air was thick with anticipation as Matt tried not to gag in disgust, his jaw aching from the stretch and abuse. He could feel Brick's breath on his face, hot and heavy, before he stepped back.

     "Look at you, taking it like a ~good boy~," Brick mocked. Matt could feel the vibration of his voice, the sarcasm dripping from every syllable. He braced himself as Brick moved closer, the heat of his body radiating off him in waves. "But I think I changed my mind..."

     Matt’s tension didn’t ease. He wasn't sure what was to come, but he was certain it didn't involve mercy. His breath caught as he felt Brick kneel behind him, hands at his waist.

     Brick pushed up the black shirt, undid Matt's pants, and bared Matt's ass quickly. His hands were rough and calloused, tracing Matt's body with a possessive hunger. He grabbed Matt’s ass, spreading his cheeks and exposing his tight hole.

     "You'll do nicely," he growled, his voice a low rumble that sent shivers down Matt's spine. He pulled out his dick, already hard and eager, and spat on it. He pumped himself a few times to spread the spit, and shoved into Matt all at once.

     Matt SCREAMED. The sudden intrusion was a sharp burning pain that radiated out from his core. He could feel every inch of Brick's cock as it stretched him, could feel the way it twitched and pulsed with the man's arousal. Matt's own cock gave a traitorous twitch as Brick's dick brushed against his prostate, but it quickly flagged with the pain.

     Brick didn't hold back. He pounded into Matt with a relentless rhythm, his hands gripping Matt's hips hard enough to leave bruises. He was chasing his own pleasure, his own release, and he used Matt's body like a tool to get there. Matt could feel the sweat dripping down Brick’s body, could smell the musk of his arousal, could hear the harsh, ragged sound of his breath.

    Without warning, Tiny’s cock pressed against his lips, hot and hard. Matt could smell the musk of his arousal, the salty tang of pre-come. He gagged as Tiny thrust into his mouth, the sudden intrusion painful. Tiny was not tiny. His jaw ached, his lips stretched tight around the thick girth.

     As Brick continued his assault on Matt's ass, Tiny fucked Matt's face viciously, his hips slamming forward with every thrust. Matt could feel the wetness of his own saliva, the slick slide of Tiny's cock against his tongue. The taste was overwhelming, the musk of his arousal mixed with the metallic tang of blood from where Matt had bitten Brick earlier.

     Matt's breath came in ragged gasps, his chest heaving with the effort of trying to breathe through his nose. His jaw ached, his lips numb from the stretch. He could feel every vein, every ridge of Tiny's cock as it slid against his tongue, the slight saltiness of his pre-come making him gag.

     Brick pulled out suddenly, leaving Matt feeling aching and sore. He could hear the sound of conversation behind him, but couldn’t make out the words. Before he could process what was happening, Brick was slamming back into him, but this time he was shifted to the side, with someone else next to him. Leo, holding his own dick with his unbroken hand, pushed into him alongside Brick.

     Matt screamed around Tiny’s cock, making the man groan. Matt’s body tensed as he was stretched even further, the burning pain intensifying as Leo pushed against his internal walls. He could feel the way his body was being forced to accommodate, could feel the way his muscles were being torn and stretched, the way Leo’s push was made easier by the blood beginning to trickle from Matt’s rim.

     Matt panted, his body trembling. They didn't give him time to adjust, pulling him back as they thrust forward, driving deeper, harder. Matt cried out, his body clenching, his breath coming in ragged gasps. They continued to pound into Matt, the tandem penetration a relentless assault on Matt's senses. Matt could feel the way his body was being used, could feel the way Brick and Leo were chasing their own pleasure, their own release.

    Tiny's hands tightened on his mask, his grip painful as it caught some of the hair beneath. He pulled Matt's head further onto his cock, forcing it deeper into his throat. Matt choked, his body convulsing as he struggled to breathe. Tears began to well in the corners of his eyes, his nose beginning to run from the effort.

     "Fuck," Tiny groaned his voice a low growl. "Such a good little slut." Matt could feel the vibrations of his voice, the mocking taunt humiliating him further. "Jackson, you got to try him," he said to the Pro. "You want next?"

     Matt had lost where the Pro--Jackson--was in the chaos of the assault, finally sensing him as he stood next to Tiny. His scent finally joined the others in arousal, his dick already in his quickly pumping fist.

     "No."

     Matt was relieved that there was at least one he would be spared.

     "I want to see how much the Devil can take."

     Matt gasped in a lungful of air as Tiny pulled out, lightheaded with the rush of oxygen. He prepared to have Jackson try to shove in next to Tiny, not sure how they'd both fit within the o-ring. Maybe they would take it out and Matt would finally be able to snap at them and show them what the Devil could do.

     But Jackson sat down next to Matt and began to slide under him, threading his legs through Matt’s, tangling between Brick and Leo’s. Jackson positioned himself at Matt's entrance, his cock hard and demanding. Matt cried out as best he could around Tiny's dick, his body tensing as Jackson shoved his way in alongside Brick and Leo.

     The world shrank to a single, impossible point of pressure. The violation was a burning stretch, a line crossed into raw, tearing agony. 

     Jackson's cock shifted against the other two already tearing him, the pressure overwhelming, the pain sharp and biting. Matt's body protested, the tearing spreading and making his breath hitch as blood began to stream down his legs.

     The conceptual walls between inside and outside, between self and other, began to collapse. He was not a man being assaulted. He was a site. A space being filled beyond its design. The integrity of his own form was dissolving under a force that did not recognize its limits.

     His consciousness began to drift. He allowed it to happen. He abandoned the burning, tearing map of his body and retreated into the sensations of the world beyond. He became the grit on the concrete beneath his knees. He was the precise, slow rust-flake drifting from the beam above.

     He was the steady chill of the steel in his mouth, the exact frequency of the buzzing fluorescent light two blocks away, the rhythmic lap of water against the pilings in the Hudson. He was anything, everything, that was not the fragile, breaking vessel anchored to this spot.

     He was the warehouse. He was the city. He was not here.

     Matt was dragged back to reality by one of them grabbing Matt’s cock, pumping him, trying to get him to come undone as he was being assaulted and further add to his humiliation. Matt was almost glad that the pain was too much, relieved when the hand eventually gave up when he remained flaccid.

    But his dissociation had broken. He could feel every inch of the cock burying into his throat, and the three tearing into his hole. Every ridge, every vein, every relentless thrust, and every moan of how tight he was or how good he felt around their cocks. The room was filled with the slap of skin against skin, harsh breaths and groans, and the wet squelch of each invasions sliding in and out of him.

     Matt could feel Tiny's cock twitching in his mouth, the slight pulse of his veins as he neared his climax. He braced himself as Tiny's grip tightened, his hips slamming forward with every thrust.

     He finally tipped over the edge, his cock pulsing in Matt's mouth. Matt could feel the hot splash of his come against his tongue, the salty taste overwhelming. He swallowed reflexively around the sudden influx before closing off his throat and trying to force the come out of his mouth.

     Tiny finally pulled out of his mouth, his cock sliding free with a wet pop. The come that Matt had tried to push out finally flowed free, dripping past his lips and down his chin.

     Matt gasped for breath, his chest heaving as he struggled to catch his breath. He choked on some of the come that hadn't escaped his mouth yet, pulled back into his throat as Matt tried to pull in air. The oxygen made him dizzy and felt cool on his lips, his skin stinging where Tiny had gripped him.

     Tiny stepped back, his presence fading. Matt could hear the rustle of clothing, smell the faint scent of sweat and the musk of arousal fading as Tiny stepped away, the faint sound of laughter following him.

     One by one, the thrusts of the other three grew erratic, their breaths coming in soft short gasps. Matt could feel their cocks pulsing and twitching, their bodies tensing as they neared their own climaxes. One by one, they gave a final push, riding out their climaxes as they spilled their seed deep inside Matt, filling him with their come.

    The final, crushing weight eventually withdrew. The hands vanished. The ragged breathing and coarse laughter receded, leaving only the heavy, satisfied silence of the spent.

     Matt hung limply in his bindings. His body was a single, exposed nerve, screaming a constant, static report of violation. Every pulse of his heart sent a fresh throb of raw agony through torn, burning tissues. The cold air of the warehouse was a searing scrape against skin that felt flayed. The rough fabric of his pants, still tangled around his knees, was an unbearable abrasion.

     The world was a smear of overwhelming input. The chemical reek of sweat and sex and blood was a solid thing in his throat, thick enough to choke on. The distant drip of the pipe was a hammer blow against his skull. The low thrum of the city outside was a physical pressure.

     His mask sat askew, one side of it damp and stiff with drying filth, but was at least still on. But it no longer felt like a part of him. It was just another piece of debris littering the violated landscape of his body.

     They did not touch him again. No one offered a cruel cleanup, not even the mockery of restoring his dignity. He was left exactly as they had finished with him. Broken open, exposed, a ruined testament to their passing. A product awaiting its buyer.

     In the echoing stillness, broken only by their shifting feet and low murmurs, Matt drifted in the tide of his own pain. He was an anchor sunk into an ocean of hurt. He did not plan. He did not strategize. He simply endured, a raw, aching consciousness waiting for the world to change shape once more.

    Finally, a new presence entered the periphery of Matt's shattered senses. It was a heartbeat. A slow, powerful, and controlled rhythm. It came from just outside the warehouse, positioned near a window. It was one that wouldn't offer a view of Matt's support beam, but would grant a clear line of sight on Leo, Vinny, and the others as they lounged by the packing tables. A tactical assessment point.

     A grim relief pierced Matt’s haze, a small part of him glad that his current state was shielded from Frank's gaze. At least his dignity would be spared for a little longer.

     The heartbeat moved to the front door just as Vinny grumbled, "...should’ve been here by now."

     When Leo replied that Frank would come because he wanted this more than they wanted the money, Matt heard Frank's soft sardonic huff. Acknowledgment. Judgment.

     The door swung open with a deafening creak that tore through the warehouse’s tense silence. Every head snapped toward the sound. Backlit, Frank filled the doorway, his silhouette a mountain of shadow holding a heavy military duffel bag in one fist like it weighed nothing at all.

    Frank's gaze passes over the thugs, lingering on Jackson by the office door. Then his eyes found Daredevil.

     Chained. Exposed. Mask twisted and stained. A ring gag still in his mouth with come dripping off his face and chin, and legs chained spread to reveal a mess of blood and come.

     Frank’s expression didn’t change. Not a muscle twitched. But inside, a silent fury ignited, a forge-blast of pure rage. The duffel bag hit the concrete with a thud.

     "Castle. You... you made it," Leo squeaked, trying to sound in control.

     Frank gave a slow nod, his eyes never leaving Matt’s bound and broken form.

     Vinny limped a step forward. “So. You got the money?” A leer twisted his face. "We’ll even give you an hour alone with him. You wanna take a turn, it’s on the house. Consider it a... gesture of goodwill."

     Brick chuckled, a low ugly sound. "Hell, I’ll even watch. Long as I get to see you peel that mask off. If you’re into that."

     Frank saw red. His foot hooked under the duffel bag's strap and kicked it spinning across the floor as a distraction. His hand went under his jacket and came out holding a M1911.

     Jackson was fast, his own hand already moving. But Frank was already aiming. Jackson dropped, a neat, dark hole drilled between his widened eyes.

     Brick and Tiny fumbled for the pistols at their hips. Frank’s barrel shifted. A second shot. Brick clutched at his throat, a wet, choking sound bubbling from him as he collapsed. Tiny brought his gun up in time for Frank to shoot his hand, the weapon clattering away. A third shot took him in the jaw, dropping him with a gurgled scream to thrash on the floor.

     Vinny tried to scramble backwards, his hand clawing at the pistol in his waistband. He was too slow. Frank closed the distance in two strides. He didn’t speak. The muzzle pressed against Vinny’s temple and roared.

     Frank turned. Leo was on his knees, hands raised, words of pleading tumbling from his lips in a desperate, incoherent stream. "Please, no, we had a deal, we’ll just go, please--"

     Frank shot him. Leo’s body jerked and then lay still beside his partner.

     Internally Matt recoiled at the executions. But he silenced his usual speech. He didn’t plead for mercy for them. Partly because he knew Frank Castle was not a man to be reasoned with in this state. Partly because another part of him, a raw and furious part he would never acknowledge, felt nothing but a cold satisfaction.

    Frank moved toward him, his steps deliberate and slow. On his way, he bent and scooped up a heavy pair of bolt cutters from the clutter on the floor.

     He stopped a few feet away, his voice low and flat. "I’m going to touch you. Get that thing out of your mouth."

     Matt managed a small stiff nod.

     Frank's hands were impersonal, efficient. He worked at the tight knot behind Matt’s head, the pressure on the sore spots of his scalp making Matt hiss. Once the nylon was loose, Frank carefully pried the cold steel ring from his mouth, slick with saliva and come. Matt heard it clatter and skitter across the concrete as Frank tossed it aside.

     "Hands next?" Frank asked, his voice still that same careful monotone.

     "Yes," Matt gasped. His voice was raw with abuse. A loud snap, and the terrible tension on his shoulders and wrists vanished. Matt’s arms dropped, and he slumped forward, catching himself on his hands with a grunt of pain. He stayed there for a moment, head bowed, just breathing, letting the blood flow back into his screaming muscles.

     Frank gave him that moment.

     With trembling, clumsy hands, Matt reached down and pulled his pants up and fastening them, reclaiming of a shred of decency.

     "Ankles," Frank stated. He moved down, and two more snaps of the bolt cutters freed Matt’s legs from the iron rings.

     Frank stood, dropping the cutters. He’d planned to just leave the medkit he brought in the duffel bag. Let him patch himself up and get himself home, if he could. But looking at the hunched, shaking figure on the concrete, seeing the mask stained and twisted, he couldn’t.

     "Can I help you up?" Frank asked.

     Matt chafed at this level of care that the Punisher had never before shown Daredevil. But this was also a new situation, one that he thinks Frank may have seen the aftermath of one too many times. After a beat, Matt gave another weak nod. "Yeah."

     Only then did Frank step in. He ducked under Matt’s arm, his own shoulder a support. He took Matt’s weight easily, hauling him to his feet. Matt bit back a cry as his injuries shrieked in protest, his legs buckling. Frank adjusted his grip, bearing most of the load.

     Together, they made a slow, limping procession through the warehouse, past the cooling bodies, toward the open door and the van waiting in the alley beyond.
