Mark fingers her roughly against the wall, her damp panties pushed just far enough to the side to fit his hand.  His own pants are pooled around his thighs, cock straining in its restrictive metal cage.  He rubs it right between the juncture of Helly’s thighs, hard metal pushing against her clit in time with every thrust of his fingers.  It's a weird sensation to dry hump metal instead of the softer, warmer skin of his cock that she’s used to, but she can't say she hates it.  Helly's so wet she's dripping in between the slots of the cage, slick reaching his restrained cock.

Mark buries his face in her neck as he keeps her pinned, mouthing at her shoulder and nipping the tender skin of her throat between his teeth.  For a second, Helly wonders if he’s keeping his head down to stop from kissing her.  She shuts the thought down just as fast as it occurs to her.

Helly groans out as his fingers curl inside of her, rubbing at the spot he’s long learned makes her moan.  She closes her eyes and imagines his cock in place of his fingers, even though it's been so long she can hardly remember what it felt like to have him inside of her.  

If she knew this was gonna happen, that he'd be caged like an animal and prevented from ever coming again, she would've fucked him way more than two times.  Helly should've pulled him aside with her for every bathroom break, for quickies in the storage room and kitchenette and out in the halls whenever they were alone.  If his outie was gonna find out anyway, they shouldn't have given a fuck about who saw them and when and where they got to touch each other.

She waited too long, scared of making a move, scared of ruining their tentative, occasional "arrangement", and now they’re both paying the price.  The thought that they could only ever be together twice, and might not get to ever again, makes her heart ache.  The thought of all of their lost, wasted time makes her sick to her stomach.

It doesn't feel right to cum when he can’t, when every time he gets aroused, metal bites into his flesh and he can't even be touched directly, let alone have an orgasm.  She doesn't want to touch herself ever again without him.  But Mark had insisted.

“I don't care if I can't cum,” Mark had said.  “It doesn't feel anywhere near as good as when I watch you do it.”

She’d tried to argue with him, to tell him it felt the same for her, too, but he wouldn’t listen.

“He's taking everything from me,” Mark had practically begged her.  “You can't let him take this too.  Please, let me show him that he can cage me like an animal and try to take away my pleasure, but he can't stop me from touching you.  Let me show that jackass he doesn't own me, that he can't stop me from living my life.  If I'm only allowed to be alive for eight hours every day, I want to live every minute how I choose.”

So Helly had let him.  Let him pin her against the bathroom wall.  Let him push her soaked panties to the side, let him push one of the last unrestrained parts of himself inside of her.  His outie could take his cock, but he'd never be able to keep her from his mouth or these hands.  No matter what he tried, they'd always find a way around it.

And Helly had insisted on undoing his belt, shoving his pants to his thighs, lining his caged cock up with her slick pussy to grind against it as he touched her.  Even with every sensation dulled and trapped, she still wanted to find a way to make him feel good, too.     

“I want you inside of me,” Helly gasps out before she can think twice about it.

Mark fucks his fingers inside of her a little harder.  He slams them into her as deep as they can possibly go, until the lips of her cunt wrap around his knuckles and slick drips into his palm.

"I am inside of you," he breathes.  His eyes find hers, and something is pleading within his gaze.  "I'll fuck you as hard as you want."

Helly shakes her head, a lump forming in her throat.  "Inside of me.  I mean really inside of me."

She angles her hips forward, rubbing her pussy against the thick, blunt tip of his cage until he gets the point.

Mark lets out a dry laugh, gesturing below them to where the hard lines of metal meet her slick entrance.  “Helly, you know I would love to but—”

“I know, I know,” she soothes.  “You're in that cage.  But... what if we tried it anyway?”

He raises his eyebrows, mouth parted a little as he stares at her.  Waiting for her to back out, waiting for her to admit that she's joking.

“You can't possibly mean…”

“You fuck me with that cage on?”  Helly finishes boldly, heat rising through her cheeks at the mere thought of it.  It's not just embarrassment.  The more she thinks about it, the more she's sure she wants that metal-lined cock inside of her.  "Yes, I do.”

“Helly, we can’t.”

“Why not?”  She says stubbornly.  “It's shaped like your cock, you know.  It's not like you're trying to shove the MDR orientation booklet up my pussy.”

“But it's…” Mark waves his hand helplessly.  “Thick?  Metal?  It can’t possibly fit inside you.”

“So what?  I like a challenge.”  Helly grins wildly, refusing to drop her daring gaze from Mark's eyes.  He sighs, shoulders drooping, but he should know her well enough by now to understand when she’s not fucking around.  Helly’s gaze drops past the sad arch of his body to his belly.  A thick dusting of dark hair peeks out under his scrunched-up dress shirt, leading to the thick, titanium ring wrapped around his shaft and balls.  As awful as the cage is for Mark, she’ll never get sick of the sight.  There’s something about his hard cock, straining helplessly against the metal cage as precum leaks from the hole at the tip, that sends heat straight to her cunt.

“So… do you wanna at least try it?”  Helly prompts.  His cock twitches almost violently against the metal bars in response, and she grins.  She doesn’t even have to look up to know his answer.

Instead of immediately pushing the tip of the cage into her cunt, Mark continues to tease her entrance with his fingers.  Helly gasps as his third finger presses into the slick ring of muscle, sliding in to join the other two already inside of her. 

“It’s bigger than I am,” he explains.  “I need to stretch you out first if I’ll have any hope of fucking you with that thing.”

She’s only ever had two of his fingers in her at once, which usually feels like the right, comfortable amount.  But with his thick ring finger added, she’s almost uncomfortably full.  He rubs his thumb over her clit, sliding it down to dip just slightly into her entrance, and she gasps as he stretches apart the muscles of her cunt.  Mark scissors his fingers inside of her, stretching them out and pressing against each wall of her pussy.  Each rough thrust of his fingers is almost too fast, but she’d never admit that.  She doesn’t want him to second-guess her offer for a second.

Helly wiggles her hips impatiently against his fingers.  “C’mon, fuck me already,” she cajoles, appealing to the desperation she can already sense running through him.  Being edged for weeks would break anyone’s patience.  “I’m ready for you.  I need you inside of me.”

She can see his self-control waver.  “Okay, um…” Mark scans the room, the wall they’re pressed against.  “Should we lie on the ground?  That might make things easier.” 

Helly nods, immediately moving to lie back on the tiled floor.  She hikes her skirt up to her waist, sliding her panties down her legs so Mark has more room to settle between them.  He reaches in between her thighs as he kneels on the floor, lifting her hips onto his lap to meet his cock.  The first brush of the cage against her cunt sends a wave of heat through her.  She’s already had his cock inside of her.  She’s just about had four of his fingers.  This can’t be much worse.

As the hard, blunt force of titanium pushes into the sensitive flesh of her cunt, Helly suddenly realizes how completely wrong she is.

The unmalleable feeling of hard metal slowly entering her is something she’s never quite felt before.  She can feel each thick ring individually as it sinks into her pussy, filling her up completely, rubbing against her ridges in a way that’s not entirely unpleasant.  Helly lets out little, frantic, overwhelmed breaths as Mark pushes into her, and hopes he thinks she’s just moaning.  Once the tip is inside of her, he slowly lowers himself over her body, letting gravity push his cock deeper in.

After a moment, it’s too much.  “Wait,” Helly breathes, stretching around the metal cock, letting her cunt adjust to the thicker length.

Mark pauses for a few seconds.  Then, almost unintentionally, his hips buck forward the slightest bit.  Helly gasps, caught between the pleasing feeling of fullness and the ache of being stretched more than she can bear.

“Sorry,” he offers, unable to look her in the eye.  “It- it felt really good.  You feel really good.”

Helly’s cunt clenches around him at the praise.  Heat fills her chest with the thought that even now, she can still bring him pleasure.

This time, she's not sure if her pussy sucks him in or if he's bucking against her, but his cage slides in another inch.  It hurts and it's amazing and it's too much and not enough and fuck it, she decides.  If this makes him feel good, she'll deal with the consequences later.  Helly links her hands around the back of his neck, pulling him in closer.

“Fuck me,” she whispers directly into his ear, suggestively bucking her hips back up as much as she can.  “Fuck me like you want to.  Fill me up with your cock.”

Mark whimpers, control starting to slip.  He slides his caged cock into her completely with one thrust, hard flesh and harder metal sinking to the hilt inside of her.  The new stretch makes her burn, the ache of it radiating between her hips even as her clit twitches for more.  

Helly cries out at the feeling, some new sound between a cry and a moan.  Her head lifts, and before she knows it, she's biting down on Mark's shoulder, trying to find some way to distribute the pain.  She must be biting him hard, too, because Mark responds with his own pained groan.  He can't stay still inside of her as she stretches around him, drawing back from her in tiny thrusts as he tries to escape her teeth.

“Fuck, Helly,” he grits out, pulling his body away from her sharp mouth.

“Sorry,” she gasps.  The word comes out cracked, shaky.  Helly realizes she's shaking under him, too, every bit of her skin drenched in sweat and rippling with waves of both pleasure and pain.

“Are you okay?  I don't want to hurt you–” Mark starts, words strained.  It sounds unconvincing even to her.  She's sure he doesn't want to hurt her, as much as he's always taken care of her.  She's also sure that, right now, it'd take a miracle to pull him out of her pussy.  That this is the closest thing he's felt to unrestrained pleasure in weeks, and it'd be the hardest thing in the world for him to give it up.

“I don't care,” Helly says firmly.  “And I don't want you to care.”  She's starting to get adjusted to the thick length inside of her, the uncomfortable press of metal against muscle.  The pain’s not gone completely.  But she's learning to adapt to it, like everything else in this godforsaken place.  It's not like this is the ideal way for them to fuck, or the way she would've chosen it, but when has Helly ever gotten to choose something in her life?  She takes what she can get and makes the most of it.

“Fuck me, Mark,” she pleads.  “I want you to use me.  I don't want you to care about hurting me, as long as you can use my pussy to make yourself cum.”  

Something inside of him snaps as he completely loses control.  Mark pounds into her ruthlessly, hips bottoming out inside of her again with one thrust.  Helly's lips part at the overwhelming feeling of being stuffed full of flesh and metal.  When he fucks her, it’s with both the base instinct of an uninhibited, feral animal and the relentless drive of an unstoppable machine.

Mark starts to chase the orgasm that’s been denied from him for weeks with no regard for her pleasure.  Every time they’d fucked for the past two weeks, he’d been using his mouth and fingers, focusing solely on getting her off.  Neither of them thought there’d ever be any alternative.  But now, Helly’s grateful she can return the favor.

Helly cries out.  It fucking hurts, and her heart pounds with adrenaline, and it's the most alive she's ever felt.

“Fuck me, fuck me, fuck me,” she chants, in time with each rough thrust of his metal-lined cock, spurring him to rut into her even harder, until the only sound that can leave her mouth is a whimper.

Even without the pain, Helly can’t quite decide if she likes being fucked with his cage or not.  It's certainly like nothing she's ever felt before.  It feels less like sex and more like having a metal pole rammed into her over and over.  The friction’s not quite right for him to fuck her, so he humps her in small, rough movements instead of properly thrusting, and the angle's off, too. The downward curve of the cage, designed to follow the lines of his flaccid cock, pushes into her at all the wrong angles.  He rubs against the back wall of her pussy with every thrust, pressing against her ass more than her G-spot.  Oddly enough, she doesn't hate the feeling.  Helly shelves the thought for later.

With him directly on top of her, his pelvis is perfectly angled to grind against her pulsing clit with each hard thrust.  The jolt of pure pleasure every time Mark rubs against it is almost enough to make up for the feeling of her cunt being practically torn apart.

He fucks her harder, and harder, using her permission to pound her, chasing something he can't quite seem to find.  Helly screws her eyes shut, buries her face in his shoulder, loses herself in the overwhelming sensation, and all but screams.  She's being loud and she can't help herself.  Helly’s sure everybody in—and out—of MDR can hear her shriek at the top of her lungs, but she couldn’t give less of a fuck right now.

Mark leans in after a particularly loud groan, and for a second, she's not sure if he's going to kiss her.  His lips brush against her mouth, and her heart all but stops.  But he's not kissing her, not exactly.  Mark bites down on her bottom lip, swallowing up her screams as he pounds into her, smothering the sound as much as he can.  She's grateful for it.  The sharp stinging pain of his canines helps to distract Helly from the blunt, pulsing pain between her legs.  Somehow, he always knows what she needs.

“Are you in pain?” Mark manages to grunt out through his own heavy moans.

“Yes,” Helly pants, too fucked through to even think about lying.  “Fuck, yes.”

It's all fucked.  It's fucked that he’s hurting her and he’s not even thinking about stopping, and it's fucked that Helly doesn’t care in the slightest.  It's fucked that her words only seem to spur him on to fuck her harder, and, most of all, it's fucked how much she wants it.

“Is that all you’ve got?”  She dares.  “Harder.”

Mark howls, and gives her exactly what she’s asking for.  It’s starting to hurt a lot more than the initial stretch.  She feels like his metal cock is tearing her cunt open.  Helly knows she's gonna feel it tomorrow, and the day after; a soreness between her legs, and a constant reminder of how hard she was fucked.  She knows that when her outie steps out of the elevator tonight, she's going to ache with a memory she wasn't present for.  And Helly wants it, wants to be marked with the knowledge of what Mark’s body can do to hers.  

Eventually, Mark growls, a long, uninhibited snarl of frustration.

“I– I can't,” he groans, words coming out sharp between pointed teeth.  “I can't cum with this fucking thing trapping me.”

Helly runs a soothing hand down his back, a surprisingly gentle gesture in the wake of his bruising thrusts.  Even in his frustration, he doesn't stop pounding into her, chasing the remnants of a long-forgotten feeling.

“It’s okay,” she murmurs, pressing against his tailbone with one hand.  “I’ve got you, and I want you to cum in me.”

Helly grabs a rough handful of his ass, pushing him deeper into her, and a sudden thought occurs to her when he groans out.  She decides to test it out.  She slides a hand between his cheeks, pulling them apart, and taps right over his hole.  The simple touch is enough to make Mark buck against her wildly.  She grins, starting to rub the tight ring of muscle in little circles, and he whimpers with every slight brush of her fingers.  It makes sense—his ass is one of the only parts of him left that his outie hasn’t restrained, where he can still feel pleasure like he’s supposed to.  Helly can definitely work with this.

She draws back, sliding two of her fingers into his mouth as they fuck, and Mark seems to get her point almost immediately.  He sucks her in greedily, wet warmth of his mouth enveloping her hand, tongue lapping at the pads of her fingers.

It’s good, but it’s not nearly enough to fuck him with.  Helly pulls her fingers out, cupping her hand under his chin.

“Spit,” she commands.  He does it immediately.

Helly collects his saliva on her hand and then spits into it, too, for a little extra liquid.  Some of the blood from her stinging lip drips into her hand along with the spit, staining her fingers red.  Their joint saliva mixes together in her palm, and her improvised lube is the closest they’ve ever gotten to kissing.

Helly brings her wet fingers to the soft curve of his ass, rubbing his sensitive hole as he thrusts into her.  It’s easier this time with the combination of their spit and her blood.  She presses the tip of her slick middle finger into his tight hole, and he clenches around her immediately.  Mark bucks wildly between her thighs, legs shaking from the slight touch against his ass.  Helly pushes in a little deeper, fucking him way gentler than he’s currently fucking her.  She finds the spot—or at least, she’s pretty sure—because a shudder runs through his whole body instantly.  Mark whines and she adds a second, spit-slick finger, pushing hard against his prostate.

“I'm gonna… holy shit, I’m so close,” Mark gasps suddenly, sounding absolutely wrecked and almost in disbelief at his own words.  “Fuck, Helly, I'm gonna—”

“Cum in me,” Helly finishes for him, arcing her hips up to grind against his pelvis.  She wants it so bad.  To give him the relief he's been on the edge of for weeks, to know that she's the result of his pleasure.  “I want you to finish in me.  I want you to fill my pussy up with your cum until it’s dripping out of me.  Fuck, Mark, give it to me,” she pleads, as he whimpers and his thrusts start to falter in her.  “I want you to give me everything you’ve got.  Breed my hole, like you own it, like you own me, like I’m yours and yours alone.  Fuck your cum into me, and mark me as your bitch.”

Mark cries out suddenly, a high, wretched whimper of pure uninhibited pleasure, that slowly turns into a long, drawn-out moan.  Something wet and warm and real, a direct contrast to the unfeeling metal cage trapped inside of her, floods through her body.

As much as she enjoys watching him finish, Helly doesn’t think she can manage it herself right now.  She’s not close enough yet, and this feeling is completely overwhelming, almost too distracting for her to have an orgasm.

But when she feels Mark cum in her, the knowledge that she still can make him feel good despite all of this, every bit of logic about not being close enough and being in too much pain or too uncomfortable flies out of her.

Her body wants her to cum with him, to share this moment.  And she does.

Helly cums with a sudden urgency almost bordering on violence, practically screaming as waves of pleasure explode out of her.  Her clit throbs against his stomach, legs shaking helplessly, cunt milking his locked-up cock as she pulses through her orgasm.  Her pussy clenches tightly around the cage inside of her, reaching the flesh of his dick beneath the metal rings with each pulse of her muscles.  Mark shakes on top of her, still breathlessly rutting through the last of his orgasm as her pussy drains every drop of cum from him.

He pulls out before he can completely collapse on top of her, still straining in his cage as his cock softens.  Through her hazy, half-lidded gaze, she can see the metal’s still wet with their fluids.  Cum dribbles out of the hole at his tip, combining with the slick of her pussy, and a wet line connects his cockhead to her cunt as he pulls back.

Helly wants to be done.  She wants to revel in the joy of their joint orgasms, in the satisfaction that she’d managed to make Mark cum against all odds.  She knows this isn’t her moment, that she’s supposed to focus on Mark and his pleasure today.

But she can’t stop the insistent pull of arousal within her aching cunt.  She feels insatiable today.

“Can we try something else?” Helly’s voice comes out rough and low, still breathless from her last orgasm.  “I had an idea.”

It feels a little hopeless now that he's already had an orgasm and is going soft inside the cage.  He probably wants to stop.  But to her surprise, Mark nods instantly.  As absolutely wrecked as he looks, he still wants to please her.  She really should know by now that Mark will give her anything she’s brave enough to ask for.

“Anything.  What is it?”

“Can you fuck me from behind?”  Helly asks, almost shyly.  “I think it might feel really good, with the angles.”

The hard curve of his cage reminds her of his fingers, when they're curled inside of her to press against the most sensitive spot of her cunt.  When he’d been on top of her, the unnatural curve of his cage had been angled all wrong.  But, Helly thinks, if she were to turn over…

They’ve never done this before.  She’s sat on his lap while refining, then later bent over her desk.  But he’s never pounded into her on the ground, while she’s on her hands and knees.  He’s never fucked her on all fours like an animal.

“Of course, but…” Mark chuckles, a little awkwardly.  “I don’t think I can cum again,” he admits. “Or even get hard.  You kind of fucked the wind out of me.”

Helly grins at him, allowing a brief moment of pride to rush through her.

“That doesn’t matter with your cage, does it?  It’s not like you’ll slip out of me,” she says slyly. “The metal can't get soft.”

Mark considers her words for a moment, eyes growing dark with arousal.  In lieu of a response, he wraps one strong hand around her hip.  Helly yelps as he flips her over onto her stomach, barely managing to brace herself on her forearms before she slams into the hard ground.

“On your hands and knees, bitch,” he growls.  Helly moans at the nickname, twitching with need before he's even touched her.  He's a fast learner.

Mark’s usual kind, gentle personality, which she’s well accustomed to, has been replaced again with this new, domineering asshole.  It scares her how quickly he can switch between roles.  It makes her wet enough to drip down her thighs.

She scrambles to get on all fours, and Mark grips both sides of her hips to roughly push her into position.  Helly spreads her thighs, waiting for him to fuck her again, abused cunt pulsing with her desire for him.  She's so thoroughly slick this time, cunt gaping wide with the memory of his thick cock stretching her open.  Gravity pulls the evidence of his orgasm from her, and cum dribbles out from her pussy, leaking between her legs onto the tiled floor.

Mark bunches her skirt up to her hips again as he gets into position behind her.  He slaps her ass experimentally and Helly groans.  He smoothes out the sensation of his stinging hand by rubbing her cheek, gentle for a moment before his nails start to dig into the soft fat of her ass.  Helly shivers against him as he spanks her again, this time on the other cheek.

She pushes back into his bruising grip, lifting her ass into the air and tempting him to fuck her, already.  He doesn't take the hint.  

“Mark, please,” Helly whines, wiggling her hips back.  “I need you.  I need to feel your cock in me again.”

He chuckles, and it's a low, sadistic sound.  “You said you were mine, right?"

His words go straight to her cunt.  Helly’s whole body pulses with arousal and she finds herself frantically nodding.  “Yes, yes, I am.”

Mark smacks her ass roughly again, and she jolts in his grip.  She's not sure if she wants to escape or get closer to him.

“Say it,” he says firmly.  “Say I own you.”

A part of her wants to be a brat.  Helly wants to pull away from him, to sarcastically point out that he's probably just doing this to procrastinate fucking her again as he comes down from his orgasm, to tell him she only belongs to herself and that he should fuck off.

But another part of her really likes seeing this new side of him.

“I'm yours,” Helly pants, and he rewards her with another harsh slap to her ass cheek.  “Fuck, I’m yours.  You own me, Mark.”

“You're mine,” he affirms, and smacks her other red, stinging cheek.  “And that means I get to use you however I want, because your body belongs to me.  I get to fuck you whenever I choose to.”  He presses one finger below her cheeks, rubbing her wrecked cunt directly and she whines.  “And I'll use this tight hole whenever I want to.  Isn't that right, bitch?”

Slick dribbles out of her at his words, cunt clenching at the thought of being his.

“Yes, boss.” The name leaves her mouth before she can think, but it feels right in this moment. “Yes, sir.”

It seems to be working on Mark, too.  “Good girl,” he breathes, sounding absolutely awed.  “You're fucking perfect.”

The strange mixture of praise and degradation thrums through her whole body.  Mark smacks her ass again, one harsh slap for each side, and her cheeks are starting to hurt with the imprint of his palms.

“Who does this ass belong to, bitch?”

“It's yours, Mark,” she gasps.  “It’s all yours.”

“Hm, I don't think that's my name,” he teases.  Mark doesn't slap her ass harder as punishment; instead, he pulls back and leaves her void of any contact.  Helly groans at the loss, wishing for pain more than pleasure, begging for anything that'll make him touch her again.  “Why don't you try that again, whore?”

“My ass is yours, sir, I’m yours,” she offers breathlessly.  

“Mm, that's right.”  He sounds entirely too smug for Helly’s taste.  Mark leans down for a moment, chest brushing against her back, and grabs a rough handful of her tits through her shirt.

“And, whose tits are these?”

“Yours, sir.”

He hums with approval.  “Good girl.”

Mark pushes apart her thighs, spreading her ass cheeks apart, and she flushes as he stares directly at her spread hole and the dripping pussy underneath it.  He draws his hand back, but instead of spanking her ass again, he slaps her directly on her cunt.  Helly cries out at the sudden mixture of pleasure and pain, shaking against his touch.  Her oversensitive cunt sings with the new sensation.

“You're such a fucking whore,” Mark breathes.  Somehow, even now, his words sound reverent.  “You want me so bad you don't even care if I hurt you, don't you?”

“Yes,” Helly cries, pushing her pussy back into his hand.  “Yes, sir, give it to me.”

He slaps her pussy again, this time, making sure to smack her roughly right over her twitching clit.  A full-body groan passes through her, and Helly keens forward, mouth dropping open.  Her lips part at the sensation, and she can’t stop some drool from dripping past her lips in her fucked-through state.  She’s slowly losing control, becoming nothing more than a worthless slut for him to abuse.  It’s terrifying to completely give over her body like this, but Mark steadily keeps her on the edge of overwhelmed without breaking her completely.  There’s no one in the world she’d rather trust with this.  

“Last question, slut.  Whose pussy is this?”

Helly can hardly find the words.  But Mark is waiting for her answer.  And if she’s really his, she doesn't want to let him down.

“Yours, sir,” Helly gasps.  “My pussy belongs to you, sir, I belong to you.”

She can't take it anymore.  She's starting to ache with the lack of anything inside of her.  Helly needs to cum so bad she can feel the sick, desperate heat of it throughout her body, pumping every inch of her veins full of pure want.  She knows Mark said he'd fuck her at his own pace, whenever he's ready, and deep down, she feels a little bad for pushing him so hard when he's still learning how to use his caged cock.  But selfishly, she doesn't care about any of that.  Helly needs him to fuck her hard, and she needs him to fuck her now, and she might just explode out of desperation if he teases her for any longer.

“Sir, can you fuck me already?”  Helly whines desperately.  “I want you to fill me up, I need to have you in my pussy again.”

She turns her head back just enough to see him tilt his head and consider it.  She doesn’t wait for his answer.  Impatiently, Helly slams her hips back onto his cage, grinding her pussy against the hard metal to get any sort of contact.

Mark stills her hips with a tight grip of his hand.  “Bad girl,” he admonishes.  “You’re such a needy slut.  Do you think you get to call the shots around here?”

“No,” she whimpers.  “But—”

“No, what?”

“No, sir,” Helly amends.  “I'm- I’m sorry.”

He grins at her, entirely wicked.  “I'll fuck you… but only if you beg for it.”

Helly's too far gone to care about how humiliating this is.  “Please, sir,” she babbles, giving in to his command immediately.  “Please, I need you to fuck me.  I want you to use my cunt, I want you to fill me up with your cage again, I want to cum around your cock.  I want you to claim me, I want you to make me your bitch.  I'm your worthless whore, and I want you to show me that nothing I do matters except being your personal toy to fuck and cum dumpster to fill up whenever you want.  Please, sir, fuck me and prove that I'm nothing more than a warm hole for you to breed.”

Her words work on him.  Helly turns her head, just in time to watch him line his caged cock up to her cum-slick entrance and slam into her pussy.

Mark ruthlessly slides back into her twitching hole, pushing the cum that’s started to leak out of her back into her pussy.  Helly’s so wet, dripping arousal down both of their legs, that she welcomes his cock back into her with ease this time.  It still hurts, metal rings still roughly stretching her cunt out, but she’s gotten used to the ache.  She’s starting to crave it.

Helly was right.  The hard, unrelenting press of titanium fills her up in all the right ways, downward curve of the cage aggressively hammering into her G-spot with every thrust.  Her mouth hangs open as he pounds into her, eyes rolling back as drool drips from her lips.  Helly drops from her position on her hands down to her forearms, then falls even further flat onto her chest.  She only manages to keep her ass up and angled at Mark’s hips as he pounds into her, the rest of her body growing pliant and useless.

As good as it feels for her, Mark can’t keep his stamina up forever.  He whimpers behind her, harsh thrusts growing weaker and more erratic.  Helly’s suddenly reminded that he’s already cum, and that fucking her so roughly must be incredibly overstimulating for his caged cock.  She loves that even though he's grown soft, the hard lines of the cage stay the same.  She can use him like this to get herself off, any time of the day, whenever she wants it.

Helly grinds her hips back into him when he stills for a moment, trying to catch his breath in between shaky pants for air.  Her ass slaps against his thighs with every thrust, filling the air of the bathroom with a lewd noise.  She can feel his whole body shiver behind her, completely overwhelmed, but he doesn't try to pull her off of him.

“Fuck yourself,” Mark commands.  “Fuck yourself on my cock until you cum on it.”

Helly doesn't need to be told twice.  She fucks back into him like he's a toy, some kind of fuck machine for her to use.  Mark’s play at dominance seems to drain from him as she envelopes his oversensitive cock in her wet cunt again.

He had talked a lot of big game when he was spanking her ass.  But now that she's actually fucking him, Mark can't do anything but helplessly whimper.  He's not really thrusting into her anymore, doesn't have the energy left to do anything but slowly twitch his hips forward, but he allows her to draw out her own orgasm using his body.

Helly knows she belongs to him.  But Mark belongs to her, too.

She imagines sliding onto his caged cock whenever she wants, forcing it inside of her whether he's aroused or not.  Feeling it get hard inside of her, until his flesh is pushing against the unrelenting metal.  Fucking him after he cums, until she's had a second, third, fourth orgasm pulsing around his metal cage.  Riding him, until he whimpers and begs for it to stop, even though she knows he really wants her to drain every last drop of pleasure from his body, and then some.  Pressing the weight of her thighs against his body so he can't pull her off.  Watching him gasp and shake as he fills her up over and over and over again.

Just the idea of it, every way he’d talked about using her, every thought she has about using him, is enough to bring her to the verge of an orgasm in record speed.

Helly grunts with each thrust, volume building up in her lungs again.  The sound of her moans, combined with Mark’s overwhelmed little whimpers, reverberate against the walls of the bathroom.  At this angle, he can’t bite down on her lip to swallow up her screams again.  So Mark does the second-best thing and pushes his fingers into her mouth.  She takes them in gratefully, sucking in his digits as he roughly presses them against her tongue.  She imagines the thick weight of his fingers to be his unrestrained cock, thrusting down her throat and coming in her mouth.

The metal cage pushes into her abdomen as she slams her hips back into his pelvis, leaving a bulge through her tummy every time he fills her up.  He presses into her G-spot, her bladder, every ridge inside of her cunt, stretching her hole out with the intense feeling of him.

When Helly finally cums, she can't hold back.  She screams around Mark’s fingers, closing her lips around his hand and biting down on the hard arches of his knuckles.  He doesn’t pull his hand back as the sharp imprints of her teeth mark his fingers, even as the rich, metallic taste of his blood starts to flood her mouth.  Mark fucks her through it, finally finding the energy for a few, final rough thrusts into her cunt.  Helly slams her hips back into him, chasing the feeling, meeting him halfway as she grinds out every pulse of pleasure from his cock.  Liquid sprays between her legs as she cums, wetting both of their thighs.  Helly shudders as she comes down from her second orgasm.  

When every last wave of pleasure has flooded its way through her body, she tries to pull away.  To her surprise, Mark holds her hips steady against him.  She can feel his body start to shake behind her.  She’d thought he’d be too overstimulated, that he’d fucked her purely as a favor to her.  But Mark slams his hips into her twice more, the feeling of his caged cock overwhelming her as her cunt twitches with the aftershocks of her orgasm, and then he’s coming again.

Twice.  She’s made him cum twice, even with his dick wrapped tip-to-balls in thick metal, even when he’s been almost completely cut off from all sensations of pleasure.  The thought is enough to send a wave of warmth through Helly, and her lips curve up into a self-satisfied grin.

Mark whimpers as he fills her up.  He’s not loud, like last time.  His moans are slight, high-pitched, utterly wrecked and entirely needy.  He sounds less like he’s having an orgasm and more like he’s been stabbed in the chest.  He twitches inside of her as a warmth dribbles out of his cockhead, less than the first time, just a slight drip of wetness that joins the slick mess inside of her cunt.  He holds himself deep inside of her for just a moment, pushing the new streaks of his cum deeper into her pussy. 

Then, finally, he pulls out for good.  Helly lets herself go flat on the tiled ground, gratefully pressing the side of her face into the cool tile.  Every single part of her aches with pain and exhaustion, from her split lip to her stinging asscheeks to the radiating pain between her legs.  Mark joins her on the ground, looking similarly destroyed.

She grins at the fucked-through sight of both of them as they lie next to each other on the tiled bathroom floor.  His wrinkled shirt and pants bunched around his knees, leaving only his dripping cage and wet thighs visible; her skirt, still pulled up to her waist, cum leaking between her legs.

There’s still so much dripping out of her.  Helly curiously presses a hand between her legs to gather up some of the liquid, and her fingers return red.

Her heart pounds.  She knew he was fucking her hard, but she didn't know she was bleeding.

“Shit,” Helly murmurs, staring at the streaks of blood on her skin.

Mark catches her gaze, eyes instantly growing wide with the realization.

“Helly, I'm so sorry,” he gasps, pushing himself up on one forearm.  “I didn’t mean…”

“Don't be,” she says lightly, brushing it off.  “I told you to use me, didn't I?  I told you to fuck me as hard as you wanted.”

“I know, but—” Mark shakes his head remorsefully.  “I asked you if it hurt and you said yes.”

He rests his trembling hands on her thighs, rubbing soothing circles into her skin without looking up.

“And I didn't stop,” he whispers, like it's almost too much to bear.  Mark sounds absolutely destroyed at the thought of wanting to hurt her, but her pussy clenches with the recent memory.

“Hey.”  Helly lifts his chin up with one hand, forcing him to make eye contact with her.  “Did I tell you to stop?”

“No, but…”

“I'm a big girl, Mark.  I can make my own choices,” Helly says firmly.  “And I chose to let you fuck me that roughly, because I wanted you to.”

He’s quiet for a few moments, absorbing her words, eyes still trained on the slight leak of blood between her thighs.

“Besides, if you're feeling that bad about it, I know how you can make it up to me,” Helly grins.

Mark looks up, hopeful, dark puppy-dog eyes practically pleading for a way for him to absolve his guilt.

“Please,” Mark begs.  “Whatever you want.  I’ll do anything for you.”

Helly gestures to her dripping pussy, still wet with a mixture of their cum and traces of her blood.

“Lick it off of me,” she commands.  “Clean my pussy up.”

It doesn’t seem like he takes even a second to consider her words.  Mark just obeys her without a second thought.  He shifts himself over her legs instantly, making himself comfortable as he settles his head in between her thighs.

“Yes, ma'am,” Mark breathes, a note of arousal making its way through his reverent obedience, and starts to lick the blood from her cunt.

He'd done this once before, a week ago, when he had just started figuring out how to get her off in spite of his cage.

Mark had gone down on her, telling her she tasted saltier, stronger than usual.  There was no disgust in his words or hint of humiliation.  If anything, he seemed to appreciate her stronger scent.  Wanted to swallow her whole, for her to smother the taste of her cunt all over his face and leave the scent lingering in his facial hair.

Neither of them were smart enough to figure out that why Helly tasted stronger than usual was because she'd started her period halfway through.  If he noticed the new, coppery taste flood his mouth, he hadn't stopped to complain.  She'd only noticed the trails of her blood, leaking down Mark’s lips and chin and tip of his nose, staining his tongue and his canines with crimson after he was already done. The sight had turned her on so much she’d asked for a second round, and he’d buried himself back in between her dripping thighs without pause.

But this kind of blood, as equally attractive as it is to see smeared all over Mark’s face, isn't a natural bodily function.  These trails of blood have been ripped out of her harshly, through pain and desperation. 

One of Mark’s hands gently caresses her stomach as his tongue brushes her thighs.  She looks down at it, wincing as she notices the angry, red teeth marks lacing his fingers and the light smears of blood over his knuckles.  They've both been unimaginably cruel to each other today. Helly takes his bloody hand in hers, lacing their fingers together, and squeezes it slightly.  They can be unimaginably kind to each other, too.

Mark presses the slightest, tenderest kiss to her swollen cunt, and the brush of his lips sends a full-body jolt through her.  He'd pounded her within an inch of her life and she'd taken it all with gritted teeth, but his gentleness is what her body can't stand.  Mark soothes the inflamed skin of her lips with his tongue, lapping gently at her pussy, and the cool drip of saliva over her flesh makes her sigh.

Mark picks up on her little groan of pleasure.  He catches her gaze, dark eyes trained on her turquoise ones, and spits on her.  It doesn't feel aggressive or demeaning in the slightest.  He keeps eye contact with her as he parts his lips, letting saliva slowly drip from his mouth onto her aching cunt.  The cool liquid pools onto her twitching pussy and Helly groans again, fully sinking into the feeling of relief.  Her pussy stings with every light brush against her cuts, but the slight insistence of pain is nothing in comparison to the soothing heat of his mouth on her.

Mark uses the tip of his tongue to spread his spit around, over her puffy lips and swollen clit and hole that clenches in time with each of his licks.  Helly doesn't think she can cum again, not after the beating her cunt had taken, not when he's barely giving her any contact.  Mark’s not even licking her to get her off—he's genuinely trying to clean her up, with slow, methodical brushes of his tongue.  But he kisses every cut and droplet of blood around her pussy clean, and her cunt throbs with need again.

Mark licks over her entrance, lapping up the cum from his last two orgasms that are still spilling from it.  His tongue pushes in deeper with each lick as he sucks his own cum out of her pussy. Mark goes slowly, gently, taking care not to overstimulate her abused cunt even as it pulses for more.  His tongue flicks over her clit, for just a second, but that’s all she needs.

Helly doesn’t scream this time.  She breathes through her orgasm, voice wavering on a helpless moan.  This orgasm doesn’t break her apart with ecstasy.  If anything, the slow, steady pulse of pleasure as Mark gently licks at her, dark eyes never leaving hers, forms her back together. 

At the end of the day, Helly cums twice from his roughness and once from his kindness.  In her eyes, they're all equally loving.

Eventually, they clean each other up to get back to work.  Mark tenderly wipes the last remnants wetness between her thighs with a wet paper towel, sliding her panties back on and straightening out her skirt.  Helly tucks his caged cock back into his pants, the metal still dripping with slick and cum and a few smears of her blood.

Helly watches a large, damp spot form over his boxers, outlining the exact curve of his dick with the mixture of their cum.  She wants his outie to undress their body later and discover that he can't control Mark, no matter what he tries.  She wants him to know that Mark is more capable of pleasure while caged and trapped inside a building than a free man who can exist wherever he wants in the world.  That, with her, Mark is capable of more happiness than his outie will ever be.
