For Science

Summary:

Chell is used to GLaDOS’ bizarre experimentations, by now. She’s been in the faculty for what feels like an eternity, crawled her way out only to be dragged back in..

She’s been nearly put to death an uncountable number of times, been forced to use dangerous and questionable objects and fluids to aid her in GLaDOS’ experiments…

Today should, by all means, not be any different.

And yet it is.

It is, because of how she feels GLaDOS’ presence hovering over her, when she wakes, compared to the simple presence of a camera in the corner. It is, because she has never before been bound like this, with her legs splayed to the sides and her wrists bound by the sides of her head…. Never been bound upon waking, nor even in any of her time in the faculty at all. Always she has only ever been trapped, never bound…

… It is, because of what GLaDOS says to her, when the super computer finally realises that she is awake.

“Remember when I said I knew how humans made more humans?”

Notes:

Ahh I was looking for an excuse to write these two for ages! And this fill was the perfect opportunity, especially with the medical inspection using noncon fingerfucking and object insertion?
And then when I was looking for a reason for GLaDOS to do something like this to Chell, running across her (unfortunately deleted) making humans line, and her clear desire to get other humans to experiment on.. It just worked out so perfectly! I couldn't be happier!
I've always loved nonconsensual medical examinations and experimentation, so this fill was a lot of fun for me to write. I only hope you like reading the piece as much as I enjoyed writing it!

Work Text:

Chell is used to GLaDOS’ bizarre experimentations, by now. She’s been in the faculty for what feels like an eternity, crawled her way out only to be dragged back in..

She’s been nearly put to death an uncountable number of times, been forced to use dangerous and questionable objects and fluids to aid her in GLaDOS’ experiments…

Today should, by all means, not be any different.

And yet it is.

It is, because of how she feels GLaDOS’ presence hovering over her, when she wakes, compared to the simple presence of a camera in the corner. It is, because she has never before been bound like this, with her legs splayed to the sides and her wrists bound by the sides of her head…. Never been bound upon waking, nor even in any of her time in the faculty at all. Always she has only ever been trapped, never bound…

… It is, because of what GLaDOS says to her, when the super computer finally realises that she is awake.

“Remember when I said I knew how humans made more humans?”

Chell does not open her eyes, even when she speaks. She tests her bindings, gently, timidly... Shifts her limbs, to feel where they are, in relation to her…

She hopes, distantly, that GLaDOS can’t see her shift, can’t see her move, but she knows beyond doubt that she does. Knows that she watches her, searches her, with each shift and tug… Knows, for she can feel her sight nigh on boring a hole into her flesh where it watches her.

“When I said that I need to make more for these tests,” she continues on, as if unaware of Chell’s struggle, “because the only human within a thousand miles of us is a test ruining sociopath?”

Chell knows that she only pretends not to see. Knows that she is playing her game again, for she has played it with her so many times before.

“Remember when I said that was where you come in..?”

She can feel it, then, when GLaDOS stops moving above her. Feels it, and falls still.

For a moment, just one, Chell inhales, and holds the air in her lungs.

She can feel GLaDOS’ eyes, or her lens, as she searches her.. Can feel it, as it watches her, more carefully now, and for the first time since she woke, Chell actually thinks on her words, rather than focusing upon her bindings.

She runs over the words GLaDOS spoke again, thinks over them, and the time she heard them before, in passing, as she made her way through the unending test chambers..

And feels, slowly, a horror dawn over her, a mortification creeping through her veins.

She tries, then, to keep her expression even. Tries, with what energy she has, to keep her brows from furrowing.. To keep her lips from pursing downwards into a scowl and giving away her distaste and displeasure..

But she must have failed, despite what she feels, for above her she feels as GLaDOS shifts away, and hears as she lets out the quietest, most unnerving of chuckles. It is something faint and distant, to be sure, but a chuckle none the less… Something inhuman and alien, when it comes from her.

“Humans are ridiculous,” GLaDOS comments then with her distinct drawl, and for the first time, Chell opens her eyes a fraction to look at her through her lashes. She watches, as her frame swivels and shifts.. Watches, as she turns away from her, even as she continues to speak.

“Ridiculous, disgusting..” she continues. “You put so much effort into an activity solely meant for creating more humans… One would think it an easy task, and yet so many depictions I researched imply that it is far more complicated than it seems.”

There is a pause then, as GLaDOS turns back to face her. A pause, as Chell watches the computer’s lens zero in upon her.

“And since it’s so… complicated… I imagine I need to… practice… before I do the real thing…”

Another pause, and Chell feels as her skin pebbles. Feels as the hair on the back of her neck stands on end, as the computer’s lens moves forward a fraction and refocuses.

“I have to make sure I’m doing it correctly, to ensure the best chance of success, don’t you agree, Chell?”

For just a moment longer, GLaDOS watches her. Her metal chassis body shifts forward then back, and her lens refocuses on Chell’s body…

And then she lets out a sigh, and swivels around with a disappointed huff.

“Oh do stop that fools errand won’t you? I know you’re awake.. And acting as if you’re still asleep won’t stop me from going ahead with this. I can always ensure you’re awake in more… unpleasant.. ways.”

That at least manages to catch Chell’s attention again. She swallows, and her eyes flutter open a fraction more, and this time when GLaDOS turns back around to face her, she flinches.

She can’t tell how she knows, but Chell has a sneaking suspicion that if GLaDOS had a mouth, she’d be smiling right about now.

“There we are,” she practically croons, though her voice is as empty and soulless as it ever is. “Now we can continue.”

GLaDOS says nothing more to Chell then, for a few moments. Her body pulls backwards, and Chell watches with creeping unease as the slats that make up the walls of the chamber shift and move to fall away. Watches, as GLaDOS’ body circles round her nude one, once, and then falls still slowly between her legs.

It is strange and unsettling, this..

She is used to being picked apart by GLaDOS. Used to being inspected like meat

But normally she is not naked before her. And normally she hasn’t just been told that she’s about to be a part of making more humans.

Slowly, from one of the missing wall panels, Chell watches as a metal arm extends. Watches, with newfound horror rising in her throat like bile, as it swivels round her body to come to a standstill between her legs..

And spies, then, the blunted syringe at its tip. Spies the white fluid that fills the thing, and immediately panics.

For a few moments, she hears nothing. Her senses focus in upon the syringe between her legs, and it is all she can do to thrash. To start trying, desperately, to tear her legs, her wrists, free of their bindings..

But of course it is for naught.

GLaDOS always has been stronger than her, and despite her desperation to escape now, despite her desperation to not be a part of this, still she is as weak as ever in the face of her strength.

It is only after several seconds of desperate, fruitless, thrashing, that Chell finally falls still. Her heart is pounding something furious, and her body is hot with adrenaline, but she falls still, and above her, GLaDOS lets out another gentle sigh of disappointment.

“Are you quite finished making a racket?” she asks dully, and Chell swallows hard.

Between her legs, the metal arm and syringe shift forward, and Chell lets out a panicked squeak.

“It is cleansing gel, you absolute idiot,” GLaDOS chides then, and despite her continued horror at the situation, Chell feels her racing pulse calm at least a fraction.

“I did just tell you this was practice, did I not?” the computer continues lecturing. “Would it hurt you to listen to me once in a while?”

GLaDOS doesn’t pause as she speaks. Chell watches, then, as she continues lecturing. Watches as the arm between her legs swivels and shifts closer. Watches as the syringe presses up against her folds, and squirms as the cold gel is pressed out of the thing and onto the apex of her thighs.

She watches, with GLaDOS continuing to drone on, as the arm swivels away, and watches still as a new pair of robotic arms takes its place, these ones with hands and fingers covered in smooth plastic.

It is only as one of them lathers the cold gel over her folds and as Chell squeaks that she finally catches what it is GLaDOS is saying, once more. Only as one of them moves to pry her folds apart, and the super computer’s metal chassis swivels towards her legs and peers from the left then the right at the crux of her thighs, that she makes out what she is saying.

“I have to ensure you are the… most… suitable… for this experiment, before we begin.”

Chell doesn’t even get the chance to ponder GLaDOS’ words, before the computer continues. Doesn’t even get a chance to question what she might mean by it, what might make her the most suitable, before the hands between her legs are prodding and poking again.

They pry her apart, at first, and though, briefly, Chell tries to snap her legs shut, the bindings hold fast and a quick chide from GLaDOS renders her still.

She can only watch and feel, then. Can only watch and feel, as the plastic robotic fingers poke and prod at her. Can only feel as they drag along the outside of her folds and make her shiver. Can only feel as they slip between them, and drag down the center… Can only feel as they brush over her clit, and send embarrassing arcs of pleasure coursing up her insides..

She watches, heart in her throat and blood rushing in her ears, as GLaDOS continues her investigation. Watches, breath held and body tense, as the supercomputer shifts her body back and forth and up and down between her legs..

Watches, and hears, as the sound of a shutter clicking fills the air not once, not twice, but three times. Watches, as GLaDOS moves again, and feels her cheeks heat with shame as the same noise fills the room.

Distantly, she hears GLaDOS’ ruminations and her observations. She hears her note the shape and form of Chell’s body, her folds, her cunt, in that unaffected and blunt voice of hers.. Hears, over the roaring of blood in her ears, as she observes to herself, ‘subject’s body is producing adequate self-lubricating fluids, as desired..’

But she can barely focus on all of that, all told. All she can focus on, right now, is the sensation of those fingers against her. Their cold plastic prying her apart, dragging along sensitive skin.. Their touch against her clit, each time unintentional, and the way it makes her insides sing

She feels shame and embarrassment as they stir in her belly with each brush of those fingers, but she says nothing, does nothing, for she can’t. She only watches as GLaDOS brings yet another robotic arm in from the side. Only watches as this time the arm brings with it a thin metal rod, and watches as she eases it inside of her, slowly, carefully. Watches as she observes Chell’s reaction, and watches as she pulls it out, and inspects both the metal rod itself and then pries Chell apart to inspect her too..

It continues like this for an age. GLaDOS brings a thicker rod, and eases it inside of her. Watches, as Chell holds her breath and shivers, gently.

She brings a rounded orb, and slips it inside Chell’s cunt. She pries her apart with her fingers, and snaps another image, then another. Chell feels as she inspects her, investigates her. Feels as her fingers prod at her folds, then at her clit, and tries, with all she has, not to respond with a cry, a moan, a gasp…

She stamps down her pleasure, and how it mounts and rises with each moment. Holds her breath, and hopes her cheeks don’t give away, in their redness, the swelling pleasure in her core, and the shame that comes with it..

And then, finally, GLaDOS stops.

The orbs, the rods, the bits and pieces from turrets, from the portal gun, all of which have been inside her, slip away with the robotic hands that hold them..

And for a moment, just a moment, Chell thinks, and hopes, it might be finished.

But of course it isn’t.

Another robotic arm swivels in from the side, again with a blunted syringe twixt its fingers, and this time, GLaDOS says nothing. Chell observes, quietly, the orange fluid within the syringe, and watches, throat tight, as the syringe makes its way twixt her legs again..

Watches, as it eases the fluid out onto her crotch, and feels, hissing again at the coolness and the way the fluid tingles against her skin, when the fingers move to lather it along her entrance.

“We don’t have any stores of the substance you humans call ‘lubricant’ in this facility,” GLaDOS states matter-of-factly then. “Propulsion gel is the closest fluid we have for such purposes, despite its dangerous properties.”

Slowly, Chell watches with unease as the syringe holding arm slips away, and focuses her attention back between her legs. Back upon GLaDOS, who hovers just beyond the crux of her thighs.

“I ran the calculations,” GLaDOS continues, voice almost singsong now, and Chell knows, then, that she only intends to unnerve her further. “With the correct quantity, and a short enough duration of exposure, you will be fiiine.”

The fingers start their lathering again, after a brief pause, and Chell feels as they shift closer to her core. Feels as they begin to pry into her.. And feels, then, the way she grows tense. Feels the way her insides tighten, and the way her lungs lock as she begins to panic once again.

If there’s one thing she’s learned, in all her time here, it’s not to trust GLaDOS. The supercomputer is sadistic and sardonic, twisted and depraved. It cares not for her wellbeing, despite what it might say, and takes great pleasure in endangering Chell, this she knows..

So her reassurance that she will be fine, especially said like that, truthfully does nothing to soothe Chell’s frayed nerves. In fact, it decidedly does the opposite, and for several moments, Chell feels as though she can’t breathe.

She feels the fingers as they continue to lather and pry and poke, feels as they continue to cover her folds, her entrance, in slick orange goop…

And then hears, distantly, GLaDOS as she chides her again. Hears as she gives another false affirmation.

“I read that things like this could happen,” she says after a long time, and for the first time since they began again, the hands between Chell’s legs stop, and she finds herself able to inhale once more.

“I read that, sometimes, the recipient could grow so tense as to make the creation of more humans.. difficult.”

A pause then, and Chell exhales, slowly, doing her level best to let her breath out evenly. To keep herself from quivering, from shaking, before the computer.

“I read that there are… certain forms of.. touching… that are supposed to make it… easier.

And with that, Chell finds her world upturned.

Her throat tightens, and her lungs lock again. She holds her breath, and feels her cheeks grow bright red…

And then she feels as the hand stirs to life between her legs again, but this time it moves towards her clit. And this time, she can tell the touch is deliberate.

The fingers brush over her clit slowly at first, up and down, back and forth. They stroke in a straight, slow, line, over the sensitive organ, and she feels as pleasure arcs up her core with each brush of the digit… Feels as shame coils in the pit of her stomach like a serpent, twisting tighter and tighter with each burst of pleasure..

The fingers begin to circle, and Chell feels herself grow tenser, tauter. Her lungs lock and her pulse races. Her eyes squeeze shut and she digs her fingers, her nails, into her palms…

And then, finally, GLaDOS stops.

For a second, only one, Chell dares hope the computer might give up.

But she doesn’t.

Distantly, over the pounding of her heart, over the roar of blood in her ears, Chell can still hear her as she makes her observations.

“It seems that the observed methods do not produce the desired outcome with our subject. Perhaps I will need to try one of the other techniques I read about in the illustrated section of the archives…”

She pauses then, and Chell lets out the breath she is holding. She feels as the computer shifts between her thighs, feels as she observes her from the left and from the right..

And then wishes her hearing were non-existent when GLaDOS speaks again.

“Additional stimulation of the chest, with added modification of the body, enlargement of sensitive areas with stimulants, may be necessary to produce the desired outcomes…”

Her eyes snap open, the moment she hears the whirring of machinery again, and though she tries to shift, when she catches the sight of robotic arms zooming towards her with true needles in their grasp, she can do no more than panic.

GLaDOS’ bindings over her body tighten, then. They grow firmer round her ankles, round her wrists, and even over her waist. GLaDOS lets out a grumble of disappointment, when she continues to try and thrash, but does not give pause in her machinations.

The arms move towards Chell without hesitation. One swivels between her legs, and two dart towards her chest, and it is all Chell can do to watch, horrified, as the syringes are pushed towards her nipples and her clit…

All she can do to feel, as the sensitive flesh quivers and throbs.. As they grow hot and tingle and twitch, when the needles are eased into them.

There is no pain, as the fluid in the syringes is plunged into them, but that does nothing to lessen the shame or horror that Chell feels. She watches as the fluid in each syringe is emptied inside of her slowly, gently.. Watches as the needles are eased out of her and lets out a breath she didn’t realise she’d been holding…

And then… falls still, as her nipples, her clit, begin to tingle and twitch. Falls still, as they begin to grow hot, hotter still, until they are burning

Just before her, GLaDOS, too, observes. She says nothing, for a little while, as the needle holding robotic arms slip away, and then simply says in a singsong voice ‘now we wait..’

For a long while, nothing happens. Chell watches, and GLaDOS watches. Her nipples and clit feel tingly and strange, but no more strange than usual…

But after a few minutes, Chell sees it.

Her throat tightens, and her lungs lock once more, as the heat within her flesh seems to grow by a tenfold. She watches, swallowing hard, as her nipples, her clit, begin to grow before her eyes.

She watches as they swell from the size of a pinhead into the size of a berry. Watches, as they swell into the size of her thumb, then into the size of a grape…

And watches, still, as they swell into the size of a cherry…

And it is just as she fears how much they might grow, just as she fears they might not stop, that they might burst, that their swelling pauses, and two more of the robotic hands swivel in from outside her sight.

Chell barely even gets to register the sensation of it, when they finally touch her again. The hand between her thighs gives a gentle and soft stroke up along her clit in a straight line, and before she can even stop herself, before she can even breathe, she is arching her back and quivering.

It gives another stroke then, and another, and the other two hands dip down the moment it does to touch upon the sensitive skin upon her chest too. She tries to clamp down upon her voice, but it escapes her despite her best efforts, and it is not long at all before the hand between her legs is circling over her clit, touching her in tandem with those upon her chest and wringing cry after cry from her lips as arcs of pleasure tear up her insides.

Dimly, distantly, Chell can hear GLaDOS still. Can hear her chiding her about how loud she is, taunting her over how this is what it takes to get her to finally speak.. To finally use her voice

But she can barely pay the super computer any mind, like this. Can barely find the strength to do anything to fight back against the computer’s taunting. She can do naught, then, to drag her focus away from the intense and overwhelming pleasure stemming from her chest and from between her thighs.

She hears, distantly, as she continues to tease and taunt her. Hears the click and snap of her lens, her shutter, as she takes photo after photo of her depravity… Hears as she claims they are important for the purpose of documentation, important for her to recreate this experiment at another date, when she finally completes it in full…

But she can do no more than accept it, despite the shame she feels. Can do no more than take what it is that is thrust upon her, and feel as her shame fades slowly into nothingness.

She feels it, when the robotic fingers ease inside of her. Feels it, when GLaDOS eases one finger inside of her and hooks it, thrusts it, pulses it. Feels, how she uses it to explore Chell’s insides, and hears her as she makes her observations…

She feels it, when she eases in a second finger, then a third, and by the fourth she can barely think, can barely even breathe.

She feels it, the way she works her fingers. Feels it, the way she pulls her up that hill of pleasure, pulling and tugging her up towards her crest with each passing moment…

Feels it, the way her bindings grow just a fraction tighter when she begins to squirm and begins to buck her hips. Hears it, the flat and dull amusement in GLaDOS’ voice when she begins to grind against her touch, unable to bear it, unable to help it anymore..

And then GLaDOS pauses, when she is finally nearing her peak, and for the first time since she has entered the faculty, Chell finds herself nearly begging. Her eyes tear up and she arches her back. Her fingers dig into her palms and she thrashes when the fingers in her insides slip away…

But she makes out GLaDOS, in those few seconds. Makes out her statement about how ‘According to some literature, orgasm is required for this procedure to be a success, so I must insert the fluid into the subject as subject peaks…’ and feels only relief at the promise of release when she knows she should feel shame.

She feels, then, the thickness of something larger as it eases between her thighs. Feels it, as GLaDOS eases it inside of her. Feels it as she fills her to the brim, and then begins to fuck her with it the same way she did her fingers.

She feels it, as the fingers begin to work faster, swifter, stronger, against her nipples and clit. Feels it, as GLaDOS’ pace between her thighs speeds, and she begins to fuck her firmer, swifter, with the rod that she’s slipped inside of her.

And all Chell can feel is relief, when she finally begins to grow swifter and faster. All she can feel is sheer bliss. GLaDOS fucks her hard and fast, and does not let up once. Chell feels her abdomen and her limbs grow tense, and a strangled cry escapes her when she peaks…

She feels fluid, slick, wet, ease into her insides… Watches, through half lidded eyes, as another syringe of fluid, slick and white and labeled with conversion fluid, empties out inside of her…

And feels, then, as GLaDOS slows. Feels as her limbs grow limp and boneless, as her pleasure washes out over her body and finally, finally, ebbs away.

Chell’s eyes slip closed, the moment GLaDOS’ motions cease. She feels as the supercomputer circles over her limp frame, hears as she takes a few more photos, but she can’t bring herself to care, in this moment. She can barely bring herself to even try and move.

For a long time, it is all Chell can do to breathe. She can hear GLaDOS, still, as she observes her. Can hear her, still, as she muses on the product, on the findings, of her experiment..

“Most animals have locking mechanisms to ensure the fluid remains in them,” she says in idleness at some stage, and it is all Chell can do to roll her shut eyes. “What a shame humans did not develop similar mechanisms, it would make the process of creating more humans far more efficient..”

She listens, for an age, as the supercomputer circles round her. Feels as the fluid inside of her leaks, gradually, out from around the rod still embedded in her insides.. Her eyes remain closed, and for a while, Chell wonders if GLaDOS intends to leave her alone like this..

But in the moments that follow, she knows that it is not her intention.

She feels, then, after an age, the fingers as they brush over her clit again. Feels, as an arc of pleasure, too strong this time, courses up her insides, and gulps down a desperate breath as her eyes snap open.

Above her, GLaDOS’ gaze remains fixed uopn the crux of her thighs, and for a little while, it is all Chell can do to stare at her, wide eyed.

“I have another experiment I should like to run,” she finally says after several long moments of silence have passed.

Slowly, the finger runs over Chell’s clit again, and this time she hiccups when another burst of overwhelming pleasure runs up her insides so sharply it almost hurts.

“If a single orgasm increases the chances of successfully completing the procedure, surely it stands to reason that if multiple orgasms are reached, the chances are also increased…”

There is a pause then, as GLaDOS’ lens zooms in then out, and shifts to refocus upon Chell’s face.

Slowly, Chell inhales, and watches as the robotic finger gives another overwhelmingly sharp brush of pleasure over her clit. Feels as this time one upon her chest moves to give a gentle squeeze over a swollen nipple as well.

She inhales, then. Yelps, and watches with wide eyes as GLaDOS’ gaze shifts back onto the apex of her thighs.

“The chances of your mental state deteriorating in the process of this experiment is.. highly likely…” she says with a pause, and Chell winces when she leans in closer to her crotch. Jerks, when the fingers begin to brush again, this time with more insistence and determination..

“However,” GLaDOS continues, voice quieter and laced with dark excitement. “I know the human body is capable of such.. And I should think your sacrifice well worth it… You don’t need your mind in order to create more humans, after all…”

There is another pause then, and this time Chell watches as GLaDOS’ gaze lifts to meet hers. Watches as the fingers move to pluck at her chest again, and as the hands between her legs begin to stroke again, softly at first but swiftly growing firmer.

It takes only seconds for Chell, then, to be gasping and heaving as the fingers resume their work against her. Takes only seconds for her to be gulping down desperate lungfuls of air and trying, already, to thrash and free herself for the sensations are too much, too strong..

Already it feels as though she is on the verge of her release, but this time it does not feel like relief as it did only moments ago. This time it feels mind shattering. This time it feels dangerous, like a tide that is certain to pull her under.

“Be a good girl, Chell,” GLaDOS purrs once she begins to weep and thrash. “Take it.. Accept it… For science.
