Author's Note: Ooh, look what I just put up. More ChellDOS smexy time. The Enrichment Center is not responsible for excessive nosebleeds. That part of this chapter was pretty much from a dream I had.

...

Moving on.

Chell had NO idea what to expect.

GLaDOS had spent most of the day ordering that she wait in her room right after she had cleaned herself up.

So she waited.

And waited.

And waited.

Chell had gotten up from her chair a few times; she paced back and forth in the room, laid down on the floor to stare at the ceiling, tossing a small rubber ball into the air. She tossed the ball into a wall across from her and it came back, hitting her square in the nose. Chell grunted sharply and held her nose with a frustrated curse.

Time seemed to pass entirely too long and she moved from the chair to the floor, pacing around and reading a few old books. She found one entitled "Little Sparrow" and laughed quietly at the title, thinking she could show it to GLaDOS when the AI decided to show up and finish whatever she was doing. She'd probably consider it a horror story. Chell giggled to herself at that. She found all of Aperture's machine life and their fear of feathered creatures to be utterly amusing.

Footsteps approached and Chell turned halfway. "It's about time," she grumbled. "What is so important that..."

She trailed off when she saw GLaDOS standing there in the doorway, dressed in her lab coat and a black blouse. Chell blinked when she noticed the long heels on the AI's feet and the predatory look full of heat that made the book slip from her hands and land onto the floor with a loud slap. The AI found such a sight to be delightfully amusing and approached her. She rested a hand on Chell's shoulder, pushing her backwards to her chair. Chell almost clumsily fell into it and stared up at her with startled, wide eyes.

"Sit." GLaDOS commanded.

"But-"

"Now."

Chell gulped and attempted to make herself comfortable in the chair - it wasn't really too comfortable to begin with - but the look that GLaDOS gave her made her squirm uncontrollably. It left a buzzing in her lower regions that was unbearably aching.

"We're going to perform a test today," GLaDOS told her, backing away a bit when she realized Chell wasn't going to try and leave. Her voice suggested she was up to something. "I've made a few modifications to this body specifically for this test in accordance with my research. I must say, humans are much more creative than I gave them credit for, not to mention indecent in the same sense. But...I'm sure a ravenous beast such as yourself will find pleasure in them."

"W-What kind of test?" Chell asked, hating how nervous her voice sounded.

"I told you I would get you back, didn't I?" GLaDOS purred, leaning forward so that their noses were only inches apart.

Chell's throat bobbed when she swallowed thickly. "Uh..."

"Try syllables and sentences, lunatic."

"How are you planning on doing...that...exactly?" Chell finally managed to ask.

GLaDOS smiled at her, tapping a finger on the human's nose. "All you have to do is sit here."

"But-"

"You either obey, or never again will I allow you to put your monkey hands on me."

That shut her up good and proper - Chell's mouth closed with an audible click. Of course, GLaDOS was lying through her teeth. Chell had activated her euphoria in a manner that couldn't just go on ignored. It was just best to lie to her to get the human to comply. It had worked like a charm because Chell had stopped talking.

GLaDOS actually found it a little nice to be wanted the way that Chell had wanted her. It seemed that the human was rather pleased with being able to grant her euphoria - well, that was a first - so long as GLaDOS herself offered the same benedictions. Well, if that was all it took to get her to perform her tests properly, then she could easily make such arrangements. They put each others lives at risk being in such vulnerable conditions. Either one had something to lose.

Besides, having her test subject in such a state of wanting would definitely be fun. Especially if she dragged it out for a while.

Oh, but where to start?

Her research showed her that humans were particularly fond of teasing one another. Sometimes it became unbearable to the point that once the teasing was done, they ultimately ravaged each other, leaving the satisfaction of their euphoric parameters much more wonderful. Of the human could do that to her after she was finished doing what she wanted... It made GLaDOS' inner circuits tingle with anticipation and her spinal relay clench with warmth. Ooh, that was a thought indeed.

But first, there was something else to attend to.

Making the human beg her for it.

After all, GLaDOS didn't just give away things for free. They had to be properly earned. And to have Chell beg for ANYTHING would be a reward in and of itself. She'd never been successful in getting her to plead to her, so this would be a far more personal victory for the AI.

Oh, music also set the proper tone for things such as these. So GLaDOS gathered a CD from her coat and placed it into Chell's radio. Immediately, a soft Jazz beat filled the air and Chell's eyes dilated at the familiar sound of it. GLaDOS smirked at her.

Let the testing begin.

O

She started off slow, allowing the human only the smallest display of her body as she moved perfectly to the rhythm of the music. Chell's fingers dug into the armrests of the chair and she squirmed, moving in tune with the AI. GLaDOS chuckled inwardly when she turned away and Chell made a frustrated sound. It was particularly adorable when she attempted to keep it quiet.

Poor thing.

Under normal conditions, GLaDOS would not have been thrilled with the concept of being put on display for a human in the way she was right now. But this was under her terms and a test of her design. Actually, from the look of Chell's earnest expressions and blushing skin, GLaDOS really had no complaints. She was still maintaining control of this test and Chell was still being the obedient test subject she wanted her to be.

She drew closer to the human before setting herself directly on top of her with her legs on either side of Chell's hips. Chell swallowed thickly, watching the AI like a tethered animal being tormented with the promise of food. Well, that comparison was almost close enough to the real thing anyway. GLaDOS just continued to smile before slowly moving her hips in a grind against the human's lap.

Chell sucked in a sharp breath, jerking a little. If she could, those armrests would have had dents in them by now.

The sound she made also rewarded the supercomputer as she felt a spike of raw heat through her circuits and in between her legs. Hm, these alterations she had made to this body were certainly serving their use right now. It actually felt rather pleasant when Chell's hips jerked against hers.

Chell's fingers twitched to grab GLaDOS by the waist, but the AI could see that temptation in her eyes as they flicked downward. She immediately took the test subject's wrists in both of her hands and held them down to the chair. The grip was firm enough that she meant business, but not enough to break the fragile bones. She really could if she wanted to, but that would have been counterproductive. Plus, she didn't want to interrupt her test to repair any damages made to her test subject.

"Ah-ah-ah, no touching, remember?" she crooned.

Chell growled with frustration, squirming against GLaDOS' body. Well, that didn't help matters having her chest rasping against the AI's. Wait...she actually had breasts? Chell looked down and noticed a distinct cleavage showing from the black blouse.

Whoa... the human thought, glad she actually didn't say that out loud. That would have been embarrassing.

Her thoughts derailed when GLaDOS leaned forward and slipped one of her hands into her singlet. Her touch was surprisingly warm against her skin and she jumped when that damnable touch traveled to her breast. It wasn't her fault, really; GLaDOS just had really good hands.

Really good hands.

"You're doing quite well," GLaDOS crooned in her ear, her hand caressing her beneath her shirt. "I should note your compliance on your permanent record, [Subject Name Here]."

Chell pursed her lips with a shudder. "Quit screwing around with me, GLaDOS!"

"I thought that was the idea."

Oh, that sneaky little computer. It was difficult to retort to that when she felt that synthetic tongue as it lathed the skin of her neck, weaving a scorching trail in its wake. It was the perfect distraction while the AI lifted Chell's singlet up to expose her breasts. When Chell finally regained some sense, she felt lips close around one of her nipples. The sensation of stabbing heat flowed from that spot all the way to the place between her legs and she arched up with a soft cry.

The sounds she made sent a flood of delicious feedback through GLaDOS' circuits. She vocalized a quiet murmur of pleasure, quite delighted to have her human continue making those noises.

When GLaDOS looked up at Chell, the human almost melted in the heat of that stare. "My sensors can detect the hormones in your body," she purred, in a near playful manner that almost seemed borderline mocking. "You must really want your euphoric parameters satisfied."

Chell groaned in protest. "Come on, GLaDOS..."

"All you have to do is ask," GLaDOS continued, trailing a finger down the human's exposed abdomen. Moving lower at at agonizingly slow pace...

Oh. I see what you're doing! Chell thought with a growl in her throat, If you think I'm going to beg you for -

All of her thoughts were cut off when that deliciously long finger slipped beneath the hem of her jumpsuit, teasingly slow. "Just one little question," the AI crooned. "That's all."

Damnitdamnitdamnit! Chell cursed inwardly, Stupid body. Stop responding!

Well, it certainly didn't help when that damned hand of hers started moving south, brushing up against quite sensitive parts of her. And it certainly didn't help that she was obviously horny. But that couldn't be helped either considering she had a drop dead sexy woman on top of her, touching her everywhere with uncanny skill for someone who hadn't been in a human form for a while. When she felt a fingertip slowly start to enter her, she bucked her hips toward it, but GLaDOS pulled away, teasing.

Oh, goddammit.

"Okay, fine! I want you to fuck me!" Chell shouted with frustration, probably loud enough to be heard by the cores. "You happy now?"

GLaDOS grinned at her and leaned forward, their lips just an inch away. "You have an absolutely foul mouth, [Subject Name Here]," she hissed. "But I'll accept that response."

Before Chell could snap back at her, that finger slipped into her and she let out a heated cry and tossed her head back - to hell with her shame right now. The way GLaDOS moved her hand, she couldn't care less about anything else right now.

GLaDOS was watching her with fascinated awe. It seemed like every little thrust of her fingers brought forth delicious sounds from her test subject. When she thought to add another finger, Chell really started making noises, writhing about on her hand and moving in time with her motions. This was quite fascinated and left her own inner thighs trembling and aching. Of course, it would have had something to do with the alterations she had made to this body to comply with human elements.

It would be interesting to see just how it would work for her.

"Oh, will you look at that," the AI purred. "It seems humans are equipped with buttons of their own. I've found two. Let's see what they do when I push them, shall we?"

When she hit those "buttons" the reaction was a sharp cry from the human, followed by a stream of desperate pleas that GLaDOS absolutely relished. Her sensors told her that Chell was close to climax, so she intensified her motions the same way the human had for her.

It only took a few minutes before Chell finally emitted that same wounded sound she had heard before, arching up and convulsing around GLaDOS' fingers. She panted rather noisily, slouching back in her chair with her eyes closed. A bright flush touched most of her body. The sight fascinated the AI further, but it definitely required more research later as her testing parameters were all but scratching at her at this point. She shook the mess from her fingers away. When Chell had finally managed to catch her breath enough to look up at the AI, GLaDOS spoke, barely able to hide her own need in her voice.

"Now you may touch me." she said.

Chell grinned at her. Oh, she was going to.

GLaDOS watched her with rapt attentiveness when Chell began to unbutton her blouse. Oh, so she was curious about these alterations she made. Well, she should be. After all, she had made them specifically for this test, so the human had to be grateful for it.

Chell was indeed grateful.

Wow. Those looked quite realistic.

She even had nipples.

Chell gave the AI a smirk. "You did extensive research, huh?" she teased.

GLaDOS nodded her head rather sternly. "Of course I did. Science takes no shortcuts in - Oh!" She let out a soft gasp when Chell's lips closed around one of her nipples. "Oh, I can - hm - see why humans enjoy this so much. It's quite interesting." GLaDOS squirmed a little.

She sounded genuinely surprised and Chell had to hold back her giggling. She continued to suck on that nipple in her mouth while feeling GLaDOS shift above her. Her other hand smoothed along her leg, traveling up her skirt. A crazy idea came to mind. If she had made alterations to her body, and if she claimed that science took no shortcuts...

"You know, I do hope your planning on completing this test," GLaDOS said, with warning, "because I will not have myself - AH!"

Chell grinned broadly when she slipped a hand between her legs. Oh, so she did make alterations to that. She even felt wet. Chell didn't know just what kind of technology was involved in that, but she didn't want to frustrate GLaDOS any more than she probably was and just continued to rub her fingers over the artificial work of anatomy.

Quite thoroughly.

GLaDOS looked quite surprised, leaning forward to steady herself with her hands on Chell's shoulders. The surprise melted away into pleasure and her eyes fluttered. "Oh! That's quite - hmm - good. I didn't expect it to be that good." she breathed, "Your chubby fingers are much more - ah -skilled than I thought."

"Chubby fingers, huh?" Chell laughed, pressing harder against her.

GLaDOS let out a startled sound when she did, arching her hips up.

"I guess I'm not the only one who gets pretty wet around here." Chell continued to tease. She rather enjoyed the AI's stunned noises, laced with unintelligible cries of approval.

GLaDOS pursed her lips and glared down at her, though it wasn't as effective when she began to sound breathless and look as sexually stimulated as she did. Well, what could be compared to sexual stimulation for a machine anyway. "The Enrichment Center would like to remind you that you have quite a foul - mmm - mouth," she growled. "and if you don't finish what you started, punishment will involve - ahh - ohhhhh..."

The rest of her threat was lost at the fault of Chell's fingers.

They slid against her before delving inside just the slightest and she registered a delicious pressure that almost disappeared immediately when Chell pulled them away. GLaDOS glared down at her again, eyes flashing with indignation and hunger.

"If you don't slide them in, I will murder you!" she spat, spiteful in her need.

Chell let out a laugh and slid two fingers into her. GLaDOS cried out and pushed herself against that hand, trying to get the most out of the sensations. This was definitely a better manner to test than what they had done before. Humans really did take advantage of the things that they were equipped with. She had no idea if it was supposed to feel as intense as it did right now, but she didn't really care. All that mattered what this wonderful, wonderful euphoria.

They found their rhythm not long after and the intense heat began to spread into an inferno. The sensory receptors beneath her synthetic flesh tingled and burned in a manner quite pleasant. The sounds she made were probably quite unbecoming though. Chell didn't seem to mind them though and GLaDOS noticed when they met gazes, the human actually smiled. Something about it made her chest feel as if it was being engulfed with flames, but she was too lost in the haze of euphoria to really think about it.

O

Chell smiled at the sounds GLaDOS made. They were musical and quite beautiful to her ears, especially since she sounded like she was going to reach her own climax quite soon. It was quite something seeing the supercomputer like this, lost in her own pleasure.

"Yes, like that!" the AI groaned. "Just like that!"

She didn't last too long either; her body seized in Chell's lap and she let out a beautiful cry before slumping forward into the human's arms. Whether or not it was intended, Chell couldn't complain. She just smiled, slowly removing her fingers from between GLaDOS' legs and carefully sliding her arms around her. GLaDOS tensed a little, her lips closed to Chell's ear.

"Well." she said, her voice calm once more.

Chell chuckled. "Well. " she repeated.

"That was...quite something." GLaDOS seemed a little bit shy in her post coitus condition.

Chell leaned her head on her shoulder. "I liked it too." She felt a slow rumble of amusement from the AI's chest and a smile against her ear. "So, did I pass your test?"

GLaDOS murmured softly before raising herself up and buttoning her blouse. She smoothed herself back into a proper appearance before climbing off of the test subject. "You passed the test." she said, with a small, pleased smirk on her face that she tried to hide. "I hope this will become quite a habit - you testing when I tell you to test and not leaving or stopping in the middle."

Chell laughed. "With testing like that? I think it might have to be."

GLaDOS' grin was actually pleasant when there wasn't malicious intent behind it. "Well then. I'll hold you to that, [Subject Name Here]." she said.

She turned and walked out of the room.

But Chell was amused when she caught a slight stumble in the AI's step.

She leaned back in her chair and crossed her arms behind her head, pleased and refreshed after what had happened between the two of them. It took a little while, but there was a whispering doubt in the back of her mind about all of it; maybe it was because of the strange fact that they were no longer enemies. They engaged in the most personal of acts that a human being could ever share with another - er, android - but she chose to ignore the doubts after a while of thinking. It was best not to ruin it.

Not after that.

GLaDOS observed the humans through the security footage.

A man and a woman with dark hair. The woman had slightly olive-toned skin. They were both wearing heavy jackets.

They were wandering toward the facility, carrying something in their arms that was bundled up in an orange jumpsuit. She narrowed her yellow optic with vague interest and enhanced the footage, watching the dark-haired humans as they placed it near the main entrance through the parking lot.

The male knocked on the door and started tugging the woman's arm. The woman seemed reluctant to leave and tugged on her mate's hand, but he forcefully pulled her away and they quickly left the parking lot. GLaDOS observed their progress as they drove away in a small red vehicle. That was the last time she had seen them.

It wasn't long before a security guard had come outside. He was apparently stunned to see the child there and picked her up. He seemed to talk to the small human for a moment before walking inside.

GLaDOS' optic narrowed.

What had just happened under her watch?
