Chapter Text

Blood pools out in a slow, awful gush.  GLaDOS said she was precision testing her new body, particularly by playing surgeon but anyone with common sense (aka Chell) would know that was a lie.  Chell internally judged the oh so morally high and mighty GLaDOS for choosing to personally torture her the first time she would experience the world in a mobile body.  GLaDOS decided to do the "surgery" in a modified maintenance cylinder, similar to one she was constructing for the scrapped co-op testing initiative.  

Her test subject was held up and restrained by mobile clamps, it’s much easier to cut open a human when you can position their body in all 3 dimensions.  The arms of the clamps had her sufferer positioned on a few trays to keep her seated and laid back.  GLaDOS herself was halfway standing up, her lanky, mechanical body was noticeably larger than her cut stress toy.  She had a few trays under her as well for her to sort of sit on, but unlike the unwilling patient before her, she had two feet on the ground. 

The maintenance cylinder was a bit too narrow for the both of them, GLaDOS leaned forward to get a better view of the gross incision.  She’s done surgery on her before, but that was quick, clean, and painless.  She didn’t have the person she hated the most conscious, squirming and restrained with a front row seat and personal participation in the gore.

With her sharp metal thumb, she digs into the wound and pulls one side out a bit.  She looked intensely at her subject's face.  Of course, she isn’t using any anesthetic, what fun would that be?  She looks at the wound again.  Glados didn't expect such a thrill from it, but that feeling buzzed through her.  She’s never directly harmed her captive in any way like this, it's always been one of her things or simply an extension of herself doing the harm.  And the excited jolt was only from a cut, oh she was about to do so many things.

Those eyes are still determined, though everytime I pinch the wound out more, her heartbeat speeds up and I can see the extremely minute clench of her jaw.  With another hand, I take out the scalpel again, and strike another lash across her abdomen, making a V.  She inhales sharply, but just a little.  I take my hand off her wound and put the bloodied grasp on her shoulder. This is nothing like before, it’s so thrilling.  I slice a larger lash across, all three incisions making a triangle.  

Instead of lifting the scalpel off at the end of the line, I stab it down.  She clenches her jaw, that’s all she does.  I lean forward, getting closer to her.  How much harm would she take?  Would she make a sound?  Would she pass out?  Would she finally break?  The sound of cooling fans reminds me to calm down.

For what? 

I don't care, I’m enjoying myself today.  I’ve earned it, and this monster deserves it and more.

Everything’s blurry.  Her arms, chest and core are covered in blood.  She rips something open again and dives her head against it again.  The agony has mostly faded, replaced by dizziness and my vision going black sometimes.  Still, every harsh move makes my lungs clench.  She’s in some sort of a frenzy, is this where I die?  Again she carelessly tears something deep between my organs.  I don’t want to look down to see the devastation anymore, so I turn my head to the side and close my eyes.  

An entire fucking hand dives under my rib cage.  She’s moving a lot more, trying to lean forward to see my insides.  Everything starts going black…

I can feel everything.  Oh god fuck I can feel everything.  I look down to see her bloodied core pressed up on my chest in a coy manner.  Her optic emoting an expression that could only be interpreted as a wide smile.

“I’ve never seen you so expressive before”

Her hand twists something deep within my chest.  My mouth snarls and I can hear her cooling fans pick up.  The bloodstained yellow optic softens to a joyful but mellow look.

“Then again, I’ve never personally torn you apart”

Something stings in my arm, I look over to see her hand pulling out the adrenal syringe.  She sets it down and takes another one off the table, injecting me with something else.  Her other hand comes out of my cavity and up to my face, still wet with blood.  I deathstare her in the eye.  Fuck you.

“Hm, what?  I can’t make it act any faster.”

The pain lessens, oh.  I turn my head to the side while my face relaxes.  Oh that feels nice.  I can still feel some stinging but almost all the pain is gone.

“Now you can’t be too angry at me”

I can hear the squelching of her bloodlust again.  I look down and see her rearranging organs and tissue.  I go back to the bliss of having my eyes closed, but something new starts getting my attention.  The way she’s in between my legs is making her waist push up against me whenever she leans forward.  Oh fuck, now she’s moving.  The pain was so much I didn’t even feel it last time.  When she moves to cover herself in blood again, she unintentionally rubs against my crotch.  

It’s either I watch her goring me, or get a boner.  Fuck it, I’m not watching that shit.

My cock is halfway out, she’s thankfully backed up a little so I can focus and will my stupid boner away.  Something intentionally touches it and my eyes shoot open.

Her hand, her fucking bloodied hand is grabbing it through my pants.  Seeing my exposed intestines make a surprise appearance as well.  It is in many ways, a horrific sight.  

“I suppose it’s a good sign that you have enough blood to sustain an erection”

Please just fucking ignore it.  Get your hand off— shit-I’m-getting-harder-please-let-my-dick-go

“I have an idea.”

That sounded maybe like she's not going to cut it off, but honestly, maybe I'd prefer that to whatever else is probably going to happen.

“You remember how my hardware gives me rewards when my conciseness perceives certain things?”

It throbs in her hand, I shut my eyes in shame.  Her grip tightens on my fully extended cock, she even does a little stroke through the pants.  I open my eyes to a squint and stare at her.  She’s looking right at me, covered in blood, with her hand on my boner.

“I’ve already let myself go today, and since I’m already here…”

She takes her hand off.  Thank fuck.

“Instead of experimenting with it later, I suppose now is the best time for me to continue being uninhibited”

She takes the scalpel and cuts through the pants and boxers and stares at it for a bit.  This is actually happening, oh my god.  She takes it into her crimson hand and the other holds my hip.  She watches it throb, watching the precum build up and join the blood on her hand.  

A gasp rips out of me when she starts to jerk me off.  The metal hands feel uninviting, but fuck, I haven’t even jerked off in like year because there’s no privacy in this fucking facility.

She takes her hand off my hip and grabs the scalpel again, carefully cutting a yellow wire in her own abdomen.  Something clearish gold spills out of it like blood.

“It’s really a nice coincidence that the most efficient place for the lubricant tubing is on the front side, and not the coolant —which if you didn’t know, would burn — alot.”  

She jerks me off with fervor, looking in my eyes to see any more expressions she can pull out of me today.  Thankfully, she’s only able to pull out occasion gasps from me, so she gives up and puts her attention elsewhere.  While she digs in her abdomen’s wires to spread the lubricant around, she grips her hand around my cock deliciously, spreading both blood and precum on me.

“Also, (quite conveniently) there’s no check for specific attached components, just the act of it on whatever the core is attached to triggers it, sooo…”

GLaDOS positions her abdomen closer to her bloodied plaything.  They both watch it go into a split in the wet bundle of wires.  She sinks down.  Both of them savor the feeling of wires slowly enveloping the throbbing cock.  When metal met Chell’s hips, she felt like she could have nutted right there.  It was tight and almost burning hot, a result of GLaDOS’s prior fascination causing her to overheat a little too much.  They both stayed still and looked at where they met, feeling the tainted warmth of eachother mixed with pleasure.

GLaDOS leaned forward until her core was on level with Chell’s, then rested its top on her neck so she could see her work.  She started to get her hands bloody again, rearranging the organs and tissues in preparation to close it back up.

The anesthetic had worn off a bit by now, and Chell felt the horrid sting of pain mixed with the feeling of having her cock wrapped around so perfectly in a slightly-vibrating-from-fans hole.  Her mouth opened and gasped whenever there was a sudden sensation, not able to grab onto anything and having to take what GLaDOS gave her.

GLaDOS kept on going like that for a while, sometimes weakly thrusting to get a feel of the reward system while she worked with putting the gore back together.  All the while, Chell was getting frustrated with the lack of movement, then pissed off when she started regaining her senses, then a horny mess again when GLaDOS moved and it pressed into the wires just right.  

Whenever she got even a little close, GLaDOS would pull off, leaving just the tip in and watching the knot lessen, then plunging it back in again.  She could hear the little hisses and gasps coming from the mouth next to her core.  

Finally, she started to close up the wound with an automatic stitcher.  GLaDOS would have felt bad closing up that conduit of pain, but the mellow throbbing inside her was too enjoyable for her to be in a bad mood. 

The maintenance cylinder was filled with the sound of buzzing fans— similarly, Chell’s head was filled with the buzz of having a year of repressed horniness catching up to her.  GLaDOS noticed the feeling of swelling again, but wondered if when she unclamped the restraints, would her test subject chase orgasm or try to escape?  While she was processing the decision, she rolled herself on the dick in a circle motion.  Maybe she could see how many times her test subject would cum?

GLaDOS was distracted with more things as well, mostly enjoying the flood of rewards and closing overheat warnings.  She freed up space in her processor, unknowingly weakening her restraints grip on her test subject. 

Suddenly, Chell shot forward, grabbing the mechanical tormenter.  Through the force, GLaDOS was pushed back and was heavy enough to dislodge the door.  This caused them both to fall onto the floor outside.  

Chell was out of containment, this was bad.  Really REALLY bad.  Of course, she had a plan if anything went wrong.  As soon as both of them had hit the ground, there was a red laser on Chell’s back.

Chapter Text

“You-  AHH!”

Chell grabbed her tightly, chest to chest, and rammed into GLaDOS.  The laser deactivated before the sparks flying up her cords rewarded her in a blinding heat.  Her back arched, causing the wires to tighten around Chell.  With the ability to control the pace, Chell slams in as fast as she can.  GLaDOS grabs Chell back, feet scraping on the flat floor for any purchase.  

“YOU ANIMAL- AauH!“ 

A deep thrust through 2 particularly tight wires sends GLaDOS into a moaning mess.  Although Chell is far gone and isn’t really aiming for anything, she doesn’t need to.  Just the burning sensation of dick touching something inside sends out ridiculous amounts of reward feedback.  

Something hits Chell’s lips, it’s a few wires on GLaDOS’s neck.  She of course bites down on them, enough to leave small marks on the rubber.

GLaDOS’s entire body locks up in climax.  Her joints stiff, her speaker refuses to let out a scream, and her vision and hearing get so cluttered with overheat damage alarms that all she can do is feel the pulsing cock inside.  Arched up, her mind goes blank from the overwhelming feeling of sex pumping repeatedly into her.  The ongoing thrusting seems to prolong it, while her speaker fizzes out mindfucked whimpers.

The thrusts start to get slow, letting her come down from the high.  She notices a thickness at the base trying to get through the wires.

“Not inside! haaah~  Cheeeell… please not inside- OH! AUH!! YES! HAuugh~”

On hearing her name for the first time, she goes seemingly wild, repeatedly thrusting as hard and deep as she can go.  

“CHELL!  PORTAMI TU- AH!”     [CHELL! take me you- AH! – Italian]

It goes through the tight wires.  Knotted.  Fucked and knotted.  Everything is still, both of them grab onto eachother loosely.  Through the half still working fans, she can hear something next to her core.  In exhales, there’s somewhat of a voice in it, moaning softly before moving to kiss the teeth nicked wires.  

Chell tugged the knot out, GLaDOS was about to say she changed her mind until it went back in, and back out, and back in.  It was a slow motion, but it still rocked the both of them.  GLaDOS lifted a hand to the back of Chell’s head.  A defensive huff came out of her nose, then relaxed when the offending hand rubbed her scalp gently.

This felt nice, neither of them trying to harm eachother.  Eventually, she pushed it in a final time, and started to paint GLaDOS interior with cum.  Without any motion, the rewards system still started to buzz her head with more euphoria for every thick rope of cum she could feel shoot into her.

Chell was half asleep, enjoying the feeling of the wires tightening around her to force out as much cum as possible.  She suckled contently on the robot's neck, not having a care in the world.  She thought that this might be her chance to book it, but after exerting all that energy and blood with a hand on her scalp lulling her, she fell asleep on top of GLaDOS.

GLaDOS stayed on the floor as well, with Chell on top of her still knotted in.  She checked her status.  Yep, GLaDOS’s body is cooked, she also wondered why she spoke Italian for some reason.  Probably just glitching.  She set a timer for 5 minutes and rested her mind as well.
