Chapter Text
Your body is riddled with pain all over, far more than you anticipated it to be. You didn’t necessarily realize what you were getting yourself into when your boss asked you to spar with him and you’re heavily facing the repercussions of the poorly made decision. You were just a simple Fatui foot soldier, you thought maybe he was going to help you, teach you so you could get stronger.
Yeah right, what a naive thought that was. If anything you thought maybe he just enjoyed beating you up when you’re already down, but of course, you’ll never voice this.
“Master Childe, please, can’t we take a break?” You ask weakly, breaths coming out short and huffed as he slightly digs his boot further against your back.
“A break? You willingly said you’d spar with me; is it right to assume you can’t take it?” Childe asks with condescension lacing his tone, a small chuckle coming out from under his breath when he notices the way you grind your teeth in frustration.
You didn’t want to give up, but being relentless beaten and thrown around for half an hour isn’t doing any favors for your health.
With a huff of stubbornness and fear of disappointing your superior, you quickly shake your head no. You brace your hands against the floor, attempting to push yourself up despite the heavy boot pressing against your back, but as soon as you even got an inch off the ground Childe roughly pushes you back down, the heel of his boot digging into your spine.
It takes every ounce of your energy to not cry out in pain, digging your nails into your palms in order to help steel your resolve.
“Trying to leave already? That won’t do.” Childe tsks, taking his foot off of your back. He motions his hand upward, and you quickly obey, your legs shaking underneath you as you regain whatever strength you could muster. This isn’t just exhausting, but beginning to be outright humiliating; you’ll never take him up on such an offer again.
Childe cocks his head to the side, waiting patiently for you to try once more. With a slight wobble, you move as fast as your body lets you, swinging your leg to knock him off his feet, but it feels like your leg hits a wall as he grabs your ankle.
”You’re too slow.” Childe chides with a disapproving frown, pulling you toward him with a quick tug on your ankle and as you try to keep your balance he roughly elbows your jaw. The impact made your head jerk to the opposite side, almost instantly falling to the ground limply while black spots appear in your vision.
The dizzying feeling in your head lasts far longer than you want it to, feeling like the training room around you was never going to stop spinning. Childe easily flips your body with a swift kick to the ribs, forcing you to lay back on your frontside.
Childe regards you for a quiet moment while you lay on the floor like a beaten animal, a minuscule quirk of a smile on his lips.
”Giving up on me?” Childe asks with a mischievous grin, crouching down and straddling your backside, his knees resting comfortably at your hips. You didn’t think much of it, knowing this is just another one of his sick ways of keeping you down when you clearly can’t even get up in the first place. You grimace when you feel warmth on your lip, knowing he had busted it; what a brute.
Had he not been your superior there would’ve been crass words and insults thrown at him by now.
“I would never, Master Childe.” You say with a shaken breath, his weight not helping your already worn lungs. This had to be some sick joke. It’s well known that Childe was strong and arrogant, but you never thought he would exert it upon you in such a way.
When you first started you had heard he was actually kinder to his subordinates than any other of the Harbinger’s, but this clearly isn’t kindness if you’ve ever experienced it.
“I suppose I should be a bit easier on you. You fought so well; truly commendable! I’m so proud of you.” Childe says in that playful tone you hated so much. You could tell he didn’t mean his words, after all you never even landed a blow on him, so his sarcastic comment only fuels your indignation.
“Thank you, Master Childe.” The words come out in a soft voice, and you can’t help but to just lay there underneath him at this point. Whether you’d verbally admit it or not, exhaustion is truly getting the better of your weary muscles.
There was an uncomfortable silence that filled the training room, and you turned your head as much as you could over your shoulder to get a look at his expression, not liking how quiet he had become. For someone who’s always talking or making jabs, it’s somewhat frightening to not hear anything at all.
Your gaze is met with a boyish playful one, his lifeless blue eyes staring back at you with mischief. Instead of feeling relaxed at his expression, you felt a chill run deep through your body, every hair standing on end.
You never truly understood why others feared Childe. Every time you were sent to do a task, or had to report to him, he was always pleasant and never commanding in a rude manner; although today’s events tell you that he clearly does have a brutish side to him. Before you weren’t scared of him like you were the other Harbinger’s, at least not nearly as much.
All of this is long forgotten in a matter of seconds as you stare into those lifeless eyes and his unsettling smile. You had never felt your mind surge with such unexplainable fear so quickly.
“Master?” You question weakly, just wanting him to say something, anything .
“Such pretty lips.” Childe states absentmindedly, and you could feel the feathery touch of his thumb on your bottom lip, smearing your blood. You weren’t sure what to do or say, your body going stock still with shock.
Before you attempt to say anything, there is a blinding light that flashes for just a moment, and the weight on your backside is far more apparent. Your eyes immediately move to the clawed metal fingers that rest beside your head, a more daunting presence on top of you.
”You should see how pathetic you look underneath me. So small, fragile, and weak . It’s truly a wonder how you even got into the Fatui being as meek as you are.” Childe’s voice is now graveled and deep, but you can still hear that irritating teasing tone.
”Are you going to belittle me or continue to spar with me?” You question, feeling anger rise up within your chest at his harsh words, but you quickly regret talking to your superior in such a way. “Master Childe.” You add on quickly, attempting to salvage your unwise choice of words.
Without a word or a witty quip to respond to you, he roughly grabs your jaw, his sharp metallic fingers digging into your skin with ease. Childe forcefully pulls your chin up to face him, craning your neck uncomfortably.
You wince as he tightens his hold, his fingertips digging into the flesh of your face without mercy or care, blood starting to slowly drip from each little pinpoint.
”Such a beautiful color on you.” Childe states with a low rumble escaping from his chest, slacking his jaw to reveal a long blue tongue that licks the blood dripping from your cheeks.
You flinch as soon as it happens, your eyes widening in disbelief and confusion, but his grip remains tight and successfully holds your head in place. You have no idea what has taken over him; this is such a stark contrast to the man you’ve come to know. Never once has he even remotely suggested or hinted at anything toward you, so your mind simply can’t catch up with this newfound behavior.
”Had I known I’d get so aroused from seeing you so disheveled, I would’ve asked you to spar much sooner.” Childe says with a soft groan, savoring the taste of your blood. He’s always kept a closer eye on you than he’d care to admit, wanting nothing more for a long while than to see your skin battered in blood and bruises.
As if your body couldn’t get any more taut with tension, you’re proven otherwise, muscles aching even further. Aroused?
It becomes almost painfully obvious what he’s referring to when his hips involuntarily twitch, causing his hardened erection to grind against the plush of your ass.
You could practically feel your mind going hazy, your heart starting to beat wildly in your chest because of the situation. Panic begins to ensue despite the effort to force it back down. You wondered how it got to this point, but it’s not like you were necessarily against it. Even if you were, what could you do? He’s a Harbinger, you’re just a mere grunt. If you were to deny him of what he clearly wants, he’d probably do something much worse just from the displeasure of your disobedience.
The realization that you’re trapped only causes an anxious ache in your heart, chest tight with worry and doubt. Would he kill you if you deny him? Would he take you anyways without a care for what you have to say?
You truly didn’t know what to do, and you’ve never felt more helpless. You’ve put your body through rigorous training for months just to prepare yourself for whatever this path might have for you, but this is not something that even remotely crossed your mind. Why would it?
”I can’t.” You say quickly out of fear, realizing that if he is going to ravage your body, there’s no way you could take him in this form; he is clearly much larger than a human’s body is meant to take. You squirm underneath him, basically clawing at the floor to leverage yourself, but the moment you moved Childe grabs both of your wrists in one hand.
”You will.” Childe demands breathily next to your ear, his long tongue licking from the exposed part of your shoulder up to your neck, groaning when he feels your pulse thumping rapidly underneath the skin.
You think for a moment that he’s lost his mind and is incapable of rational thought, but you knew whether you were prepared or not, this is clearly going to happen. With that thought you let out a shaken exhale, trying to force your body to relax. It wouldn’t do you any good and only cause you more pain if you remained as tense as you were, you know that much.
With his free hand, Childe pointedly moves a finger to the back of your neck, hooking under your uniform and pulling down. The fabric tears with ease, but a sharp hiss from pain escapes your throat, feeling your back burn as blood begins to erupt from the fresh scratch.
You look over your shoulder to glare at him, knowing that he didn’t have to dig into your skin to rip your clothing off. Childe doesn’t apologize, instead opting to lick the blood from your back, cleaning the relatively deep wound he had made.
”I did a number on you.” Childe husks with a chuckle, and it felt as if a knife was tracing over the expanse of your back when he drags his index finger against the blue and purple skin.
”That hurts.” You mutter quietly, scared of making him displeased, but also of how far he’d go if you didn’t say something. You didn’t know your limits of communication here, but trying is better than doing nothing at all.
”Don’t complain.” Childe murmurs, grabbing your left hip and digging his claws into the fattened area. You clench your teeth in pain, but it’s forgotten in seconds when he juts his clothed erection against you backside once more. Worry settles in your mind again at the feel of him, hoping that he wasn’t going to just brute force his way into your body.
Without a word Childe scoots back, moving off of you and instead behind you. He releases your wrists much to your liking, both hands slowly dragging down your sides and to your hips, fingers digging painfully into the flesh while he angles your ass upward. If his nails didn’t hurt your thoughts would be more preoccupied on just how large his hands are compared to your body.
While the thought of his cock bullying its way into your body truly frightens you due to its obvious size — the threat of probably tearing ever present — the fact that he’s overall larger than you in this form causes a small spike of excitement.
The sound of fabric shredded once more tears you away from your thoughts, warmth spreading throughout your face when Childe forces your cunt on full display for him. While you weren’t a blushing virgin, being in the Fatui has definitely made the ability to get around much harder than it already was.
”You may be shy, but your body clearly isn’t. Your pussy is drenched.” Childe coos with a raspy laugh, and you didn’t know whether or not he was making fun of you or pleased with the reaction your body is giving.
You twitch when you feel his hands move from your hips to your ass, thumbs spreading you apart. What only furthers your current embarrassment, is the fact that the small excitement you felt moments ago caused a bodily reaction you weren’t proud of. The undeniable sound of wetness from your cunt when he spreads you apart is humiliating in ways you never knew you could feel.
You jolt forward as soon as a cold touch of metal brushes against your slit, letting out a frightened cry, afraid he was going to cut you. ”D-Don’t, your fingers are too sharp.” You exclaim in panic, reaching your right arm back behind you to push his hand away. Childe sighs at this, frustrated with your apprehension.
”Would you prefer I go in without any preparation? Be grateful for my patience.” Childe responds gruffly, and you could hear the annoyance in his deep and gravelly voice. You stay silent, not knowing what to say to him and afraid of angering him further. Childe lets out a long sigh, and moments later you hear him shifting behind you.
“Tongue it is.” Childe says with a shrug, and he flips you around easily, hooking his arms underneath your thighs and his cold claws rest against your back.
A small gasp of surprise is all that you manage to do while Childe lifts you into the air with ease, positioning you above his head, his monstrous face against your loins. Your hands hold tightly onto what you assume is Childe’s hair, fearing that his arms were going to get tired and eventually he’d drop you.
”Master Childe, please-.” A choked moan erupts from your throat when you feel Childe’s tongue lick your clit, slightly curling around the bundle of nerves. Childe doesn’t keep his attention on your clit for long though, moving his tongue to your hole and swirling the outside for the a moment, groaning at your taste. There had been nights where he dreamed of how divine you’d taste, and now that he’s getting to experience it only furthers his eagerness.
Your hips grind forward, but it’s difficult with the way he was holding you so firmly, his biceps flexing underneath your thighs.
To reprimand you for moving too much, Childe turns his head slightly to the right and roughly bites your thigh, causing you to cry out in pain as you desperately try to pull him away by his hair. Childe doesn’t let up, and his teeth were so sharp the pain is akin to a burning, searing sensation.
”Stay still.” Childe commands, licking up the blood that’s spilling down your thigh from the deep indents. You wanted to curse at him for being so rough because the wound stung like a bitch, but instead you choose obedience.
”I will.” Your voice warbles with a quick nod, tears brimming your eyes at the unexpected pain. Childe notices this and shifts your hips more toward him, immediately plunging his long, thick tongue in your wet cunt to take your mind off of it.
While you could still feel the pain, the way he’s lapping at your insides overrides the searing feeling on your thigh. You could feel his tongue deep inside you, your lower stomach tingling at the intense sensation, and you can’t help yourself when you writhe in pleasure. This is something you’ve never felt before and probably never will again, it’s like he was truly trying to force his way into your cervix.
You bite your bottom lip to silence a soft whimper, your thighs twitching to close, but Childe is sturdy when keeping you open for him. Childe continues to feast on you, the big blue eye closed in what you can only assume is satisfaction. Even if you’re furious with him for all of the moments that lead up to this situation, your body greedily accepted the pleasure.
It’s only when your cunt squeezes tensely around his tongue that Childe decides to pull away, much to your dismay. ”I can’t wait any longer, you’re just going to have to deal with it.” Childe rasps, panting like a wild dog before moving over to the wall in the blink of an eye. He holds you against the wall securely with one arm while he the other hastily moves to his pants to free his throbbing cock.
You grunted at the force of the wall hitting your back, but there’s no time to voice your complaints when your throat goes dry as you glance down at a blue, ribbed, large cock that’s nearing your sopping hole. He couldn’t possibly think that thing is going to fit inside of you with such ill preparation.
You noticed that it was blue like his tongue, each ribbed detail from the tip getting bigger toward the base. All of these were futile compared to just the sheer size of his cock; it had to at least be as big as your forearm. From what was once pleasure filling every fiber of you being quickly turns into sheer panic.
”Wait-.” Before you can utter anything else he shoves his tongue down your throat in order to silence you, causing you to gag and choke while he inches his cock closer, nudging his tip against your entrance. Only when you repeatedly pound your fist against his bicep does Childe remove his tongue from your mouth, licking the tears that now fall down your cheeks.
“You’ll be okay, be quiet.” In what is attempted as one swift motion Childe thrusts up into you, the resistance of your tight walls squeezing him at the brash intrusion and immediately stopping him just barely past the tip. You throw your head back against the wall, feeling like the air had been completely sucked out of your lungs, your chest heaving as you quiver and cry out.
It hurts far worse than you expected even given how wet you are and the fact that he had speared you open with his tongue moments ago. You put your hands against his chest, trying to push him away, but Childe doesn’t relent and keeps trying to force his cock inch by inch inside of you.
”Damnit, you’re too tight.” Childe hisses, enjoying the way your cunt clamps around him like a vice, but he could barely get halfway in and wanted nothing more than to sink himself into you.
”Big- too big, please.” You heave out while weakly beating closed fists against his broad chest, feeling nothing but a painful, intense stretch of your insides each time he attempts to sink you further on his cock.
”It’ll fit if you relax for me, beautiful.” Childe hushes dismissively, using a free hand to gently and very carefully grind his palm up against your clit. He wanted to be inside you so badly, but he knew with your body being so taut the endeavor is pointless. Childe looks down, a low hiss soon escaping while his jaw slacks, enjoying the sight of seeing your hole spread open on him.
You whine pitifully when he’s able to shove himself just a little further, his ministrations on your clit willing your body to relax into the clutches of pleasure. When realizing that your body is beginning to give, Childe doesn’t waste a second to thrust into you without a care for your comfort, the force making you bounce upward in his arms.
Despite the deep gravel this form causes his voice to have, you swore you heard a low whimper when he’s able to finally sheathe himself inside of you. You look down in horror to see your stomach budge up where he’s nestled inside, unable to take anything other than quick fistfuls of air into your lungs; it was far too much.
There’s an eagerness behind each thrust to quickly get back into you, as if he couldn’t handle the small second when he pulls out to only dive back in. You felt like he was impaling you, and with each painful thrust you could see your lower stomach bulge any time he was all the way in. Eventually, even though it’s still uncomfortably painful, your cunt tries to adjust to his sheer size, slowly inviting the intrusion back in with welcome.
Childe roughly squeezed your ass, mouth salivating while he stares down at the lovely sight of his cock covered in your juices each time he nearly pulled out and thrusted back in, his claws digging into you while he essentially used you like a toy.
”Too much .” You whimper, your voice coming out in such a hoarse whisper you doubted he heard you. Unfortunately to your blushing shame your voice isn’t the only thing that’s ragged; the disheveled look on your face and drool slowly running from your lip was enough to rile Childe up further.
”You feel just as good as I imagined.” Childe states with a grunt, his head falling back as he tries to ignore the exhaustion and pain that is taking over him from being in his Foul Legacy form for too long. You blink through your tears, your lashes clinging together while you dig your nails into his shoulders, your body growing taut with the threat of an oncoming orgasm that was stolen from you earlier.
Before you can even prepare for your impending orgasm, your body comes undone with a violent shudder, legs spasming against his arms while your walls squeeze him so tightly that it causes him to shudder with a stilted thrust.
Childe pants, his jaw agape while his long blue tongue lolls out of his mouth when you milk his cock for all it’s worth, abruptly causing his own orgasm. Childe’s thrust became sputtered, sloppy while he ruts his hips up against you, trying to nudge himself as deep as he can inside of you.
After a short moment of silence, Childe pulls out slowly, each ridge rubbing against your sensitive insides causes you to groan from overstimulation. There’s a loud squelching pop when he finally pulls his cock out of you, his seed dripping from your used hole and onto the floor.
He came an absurd amount due to his size, so he wasn’t surprised, but he did frown at the wasteful mess. Childe transforms back out of his Foul Legacy form with a tired sigh, but despite the exhaustion that hits him, he makes sure to keep a tight hold on you so you don’t fall to the floor.
