Story: Twilight in Aperture Sciences

Twilight Sparkle found herself in the cold sterile place of Aperture Science Laboratories. How she got there, why she was there, and why is her magic gone was a mystery to her. All she knew was she was in this strange alien white world, having this feminine artificial voice named Gladose just telling her that she was a test subject that needed to solve the tests, even gaining a device that can create these portals to solve them. Twilight was amazed by the device, and intrigued on how it works.

However when twilight asks about the device. Why she was here. Why must she solve the tests? What happened to her magic and why she can't use it? Is there a way to get out? Gladose only answered saying "Don't worry Miss Sparkle. All will be answered at the end of the tests. Besides it is for science and don’t worry, there is cake at the end."

Twilight tried to ask the same questions again, only for Gladose not really answering her questions, only promising all was fine, solve the tests, for science, and the promise of cake. So twilight solves the tests, hoping to that the Gladose will keep her promise, even if Twilight was interested in the science and mystery of the device, Gladose and the place they inhabit.

However, as the tests go on, Twilight was starting to have a burning desire between her legs, whether it was by thinking about something about a sexual desire, or imagining a sexual fantasy, it comes and goes, but was always a distraction, but she always wanted to hide somewhere and relieve herself, but she two things stopped her.

One: She always seemed to be watched, no matter where she goes.

And Two: She wanted to be polite, knowing she was in someone else's "home" and didn't seem like it was appropriate to have some girl fingering herself in someone else's place. She had to hold back her feelings of being amorous.

However, it all changes for this latest test chamber, white panels for the floors and ceiling, with widows revealing the empty dark outside of metal walls, and catwalks. But there was a familiar circular doorway to the next test, and two white panels sticking out from the floor, standing straight up towards the ceiling and very close. Twilight looks around, thinking and plotting to see how to solve the test, only that this test seem, unsolvable, and strange, why the windows? Why is there no buttons or switches, cubes, lasers, or even turrets for that matter, but however why are there two panels facing each other in the middle of the room.

"Now this test will not be testing your intelligence, or problem solving skills." Gladose spoke as twilight was listening hoping to find the purpose of this. "This test is a very import test of being obedience to authority, no matter how strange or obscene it is."

Twilight raised an eyebrow "How obscene is this......test of obedience?" She always obeys the rules and respected the authority when she can, but that didn't stop her from questioning it, especially when the words 'strange' and 'obscene' were used. "What do you mean 'obscene'?"

Gladose responds as coldly as ever. "You will know how obscene it will be as the test progress. However, it is imperative for the success with this test that you obey every command that I give you, then you may go through to the next chamber"

Twilight was frustrated as her questions were never answered and rolled her eyes. "Fine, Gladose, what must I do?"

"That’s the spirit, now miss sparkle you do see the two panels facing each other?"

"Yes, what about them?"

"Shoot the portals upon the portals upon them to make those portals face each other."

Twilight did her job, not really in the mood for games "okay, now what?"

"Here’s where it gets strange and obscene miss sparkle, you must strip bare naked."

Sparkle shot up, wide eyed, not believing what she just heard. ".....ex....excuse me?"

"[Sigh]....I suppose I will repeat what I just said. {Rewinds her whole dialogue.} Here’s where it gets strange and obscene miss sparkle, you must strip bare naked."

".......again.....excuse me?"

"[Sigh].....do I really need to say it again. [She rewinds her dialogue again]"

But Twilight interrupts her. "I heard what you said.....but what is the purpose of this test? I just went through many testing my skills of the mind. This is just.....just....."

"Different I know, it is a test of obedience, as I just mentioned."

Twilight was just perplexed by this, she shakes her head. "....I really have no choice in this do I?"

"Well technically you have many choices." Gladose remarks. "You could obey my every order, or just sit here to do nothing with your life, or try to break the impenetrable glass to try and escape, or do nothing with your life, think about your friends and magic, never seeing them again...."

Twilight was seriously annoyed by Gladose's words. "Fine, I get it, I'll do it." Twilight blushes, stripping the orange jumpsuit and taking off the jump boots, as twilight stood there, cold and in her undergarments, her feet feeling the cold hard floor, as twilight stood there waiting for Gladose's commands.

Gladose obliviously states out. "Miss sparkle, you don't need to hide your body, no one else is watching. Well, except for me. I need to watch this in order for you to proceed. Now Strip naked." Twilight closed her eyes as she strips down, her articles of her clothing on floor, as twilight stood there covering herself, being embarrassed by this situation.

"Come on twilight, show your body, there is no reason to hide your natural beauty." Gladose teases, as Twilight lowers her arms, gripping her hands, as her arms are besides her body. "There, that wasn't so bad dear miss sparkle, it wasn't that bad at all, well except for the fact your butt is fat, your breasts are small, and somehow you are a purple horse girl with wings, and as hard phallic object adore your head, you weird purple penile head."

Twilight was never fond of others from her youth making fun of her horn saying it was a penis upon her head, this was no different. "You are reeeeeallly enjoying this aren’t you?"

"Well of course, anything for science, and besides, you may actually enjoy this, I assure you." Twilight didn’t really believe Gladose, as the artificial disembodied voice rub twilight the wrong way, like she has other intentions. Besides Twilight gives off heat of embarrassment emitting from her body being naked and all.

Gladose soon catches twilight her off guard. "Now miss sparkle, crawl into one of portals, where your butt is hanging out, and your face looks upon your butt, as if you could kiss it."

Twilight does so going in, amazed by the infinite looping effect of the portals, as if you have two mirrors facing each other, making this weird world within the infinite space.

But as soon as twilight was positioned herself on her hands and knees, as she stares upon her ass, she couldn't believe that she was staring upon her ass in such an angle, getting a good view of her plot, she had to admit, staring at her own crotch, looking upon her pussy as if there was another mare infront of her was kinda hot, and the heat of her arousal was emitting from those juicy wet li"Miss twilight Sparkle did you not hear me?"

Twilight snapped back into reality. "Huh what? Yes Gladose? What is it?"

"It is Pronounced GLaDOS. As you stared deeply into your own nether regions, as if you wanted to kiss it, you dirty sicko."

Twilight blushed by the remark.

"I was saying that you needed to kiss your own butt."

Twilight blushed. She goes in for the kiss.

"Oh, and make it meaningful, I don't mean a peck, I mean a nice tender loving kiss, as if you kissing the buttocks of your lover." Twilight blushed looking upon her ass, she closes her eyes, thinking of a particular pony in her mind, as she goes in pursing her lips, closing in for the kiss upon her buttocks.

"Well get on with it miss sparkle, I can't believe it takes you this long to kiss your own ass." Twilight slams her fist on the ground, glaring up at the ceiling.

"I'M Doing It! By Fucking Celestia's ASS! Keep Your Panties On!"

"Twilight..... I’m an Artificial Intelligence. I have no real need for panties."

Twilight Scowled, Rolling her purple eyes. She proceeded to close in, her lips tenderly kisses her own ass, such a weird feeling of her hands upon her own hips, her lips upon buttocks in such an angle that not easily achieved without the portals help. She lifts her lips off her but, getting shivers down her spine.

"I bet you like that, you little pervert." GLaDOS Remarked, Twilight was glaring at the ceiling. "Now kiss your ass, kiss all over it. Like the dirty little slut."

Twilight got out of the portals getting her clothes.

"What are you doing? I did not instruct you to stop."

"I’m sick of this, you are making fun of me." Twilight lowered her head, tearing, her stomach hurts, and her body shakes. "I'm not making fun of you miss sparkle. I’m evaluating your performance of this test."

"Calling Me a Pervert Every Time I Obey Your Stupid Perverted Commands! Insulting me! You Are the Pervert Here! Not Me! You're Getting Off on This! Your Stupid Sick Fantasy!"

GLaDOSE gave a short Pause "Miss Twilight Sparkle, this is just a test of obedience, I did not just make this up on the fly just for my amusement, you think I'm capable of just designing tests just to amuse myself as time goes on, this is for science! So why are you getting upset with these words."

Twilight whispered to herself. " 'For science', my ass, if this is for science, a scientist might as well be a bunch of perverts with weird fascinations." Twilight hugged herself.

"Well aren't you enjoying this experiment? Aren't you getting off on this?"

Twilight teared up, hugging herself tightly by the half-truth of the remark.

GLaDOS was silent for awhile before speaking again. "Tell you what miss twilight, I will keep my evaluation remarks to myself till the end of the test. Just to make it easier on you, besides, just as you said, you have no choice in the matter, you have to pass this test in order to proceed. Though to be honest wouldn't you want the challenge?"

Twilight just stood there, still angered by GLaDOS’es Remarks.

"I guess you want the easier way out then, very well just get into position when you are done feeling self-pity.

Twilight flinched from the remark, she just stood there just adjusting her feelings, even with the heavy weight of emotions pulling her insides, she got into position, ready to enjoy this degrading situation. Twilight was not doing this completely to get out of the test, even if she is trying to escape. She was enjoying this weird and wondrous experience, it was such a unique experience, she has tasted a mare's vagina, the sweet taste of her delicious nectar, as thoughts of her own experience of getting eaten out was amazing, but here, her eating her own self, is something she can't deny as a weird and amazing experience, she can't just pass this up.

"Good choice miss sparkle. Now where were we? [Rewinds entire dialogue yet again] "..ow kiss your ass, kiss all over it. Like the dir[BEEEEEEEEEEEEE]"

Twilight shot up, startled by the sudden high pitch sound. "Sorry about that, now tenderly kiss your own buttocks. Kiss it all over." Twilight stared at the ceiling, then her nice plump buttocks, she takes a breath, closes her eyes, leaning close as she plants loving kisses over her buttock as if she is giving kisses to her love and joy back at her home of Equestria.

"Good job. You [white noise.]....... Sorry, I am making an attempt to keep my opinions to myself."

Twilight rolled her eyes, shaking her head.

"Now, bite upon your ass, make a nice bite mark."

Twilight was shocked by this.

"Go on, don't be shy, you[white noise]My apologies, I really need to try harder."

Twilight had a moment, looking upon her ass, staring upon it, she closes her eyes, gently bites her ass.

"harder."

Twilight pauses.

"harder."

Twilight bites harder.

"Harder."

She Does.

"Harder!"

She Does!

"HARDER!"

Twilight bites into her Flesh, she squeals as pain shoots across her body. Her eyes shut tight from her biting herself. She hasn't noticed but her wings are unfurled by her own arousal and from the pain she inflicted upon herself.

"Okay now stop!"

Twilight lets go of her bite, panting, looking upon her bite make, as a blood tickles against her leg as it trails down, looking at the feeling her ass being bitten by her.

"You're doing well miss sparkle, very well."

Twilight blushes from the remark.

"Now, I think you may enjoy this, you need to please yourself by licking your vaginal entrance till you experience a sexual climax, or cumming as others call it."

Twilight blushes as she stares intensely upon her pussy lips, her heart pounding loudly, she tastes the sweat of her lips, as she leans her head, sticking out her tongue, time somehow slowing down, her mind racing. 'come on twilight, don't back down, all you need to do is lick yourself, you eaten pussy before, why is this....' Her tongue is upon her pussy, her body shivers, as she tastes her own pussy, as she starts feeling herself lapping up her own vagina, her own vagina, her eyes shut, lapping up those juices pleasing herself, she couldn't believe it, she was performing cunnilingus upon herself, and she is enjoying it! It was as if time was slowing down as she, moaning and groaning as she eats herself, enjoying this act of perversion. And she is loving it! She does this for several minutes, waves of pleasure washing over, controlling her body, as Twilight moans cumming upon her face, spraying her own face. She pants, head lowered, so turned on, wanting more as she reaches up for a second round.

"Good job Twilight Sparkle, get ready for your next task."

Twilight was alittle frustrated, panting wanting to taste herself, awaiting for GLaDOS's next command.

"Now take your long horn attach your head, and shove it into your vaginal entrance."

Twilight was in complete shock, she has never really done this, having her horn shoved into anyone's hole before, and there was obliviously naughty stories about it, but she never really see the appeal of it, soon twilight lowered her head she positioned her horn, her head was close enough to shove her entire horn into her nether regions, twilight gulped, as she rubs the tip against the pussy lips, she waves of shivers goes up and down her body. As she slowly shoves her horn in, she quickly goes in, her eyes shot open, her pussy clamped down on the horn, her body feels filled by this horn she stares at the ground, paralyzed by the sheer pleasure coursing through. she closes her eyes, moving her head back and forth as she starts head butting her own love tunnel as the horn starts stretching out the canal, twilight moaning by her devious act, her body shaking as her back bends moving her buttocks to slap her head, her left hand stabling herself, as her right hand reaches down to her groin, as she starts rubbing her citreous, twilight moaning, getting rougher, slamming her ass harder, her head harder, she was moaning in lust and desire, picturing herself, her horn deep in her cooch, her hand between her legs, seeing herself in the infinite loop, it was kinda funny how this experiment turned out, she slams harder and moans, She closes her eyes screaming as her nethers grasps her shaft, twitching, convulsing, pulsating. The assault of Twilight's climax weakens the limbs supporting her, she was still standing, she just stood there all four, as the afterglow of her climax washes over her, as GLaDOS chimes in.

"Well didn't you have fun, too bad for me I never get to fantasize such a sexual act, Then again I'm an Artificial Intelligence in a robotic body, I really don't know how it feels to have a humanoid body such as yours. How does it feel?"

Twilight tirelessly stares, panting from this experience, only one word flashes through her mind, panting wording it out in a low silent voice as. ".........." As if a word fully describes this feeling.

"Your next task is alittle difficult, but I highly doubt you would fail this one, are you ready Miss Sparkle"

Twilight stood there then weakly nodded, wincing as her horn rubs inside the vagina.

"Alright, you must pleasure yourself till I tell you to stop, you may stay there and ultimately keep cumming till I say stop. Are you ready?"

Twilight smiled, nodding, as her horn rubs her gspot.

"Alright then begin"

And for what seemed like hours Twilight pleased herself, horn fucking herself, flicking her clit, grabbing her breasts, eating her pussy, her ass, fingering both, going absolutely insane with it, pleasing herself, even lapping up the skin and blood, kissing and biting down on her ass, cumming so many times she lost count, not even caring, as the last thing she remembers, she had her tongue deep in her rectum, eating it, as her fingers slam harder inside her cooch, moaning loudly, enjoying the sensations, until finally she cums her last, moaning into her hole, falling down, slamming it to the ground, her hard tits pressed against the ground, panting and moaning her entire body sprawled out, her head between her legs, her rectum clamping down, her pussy twitches, spraying everywhere, as twilight lays there, panting, convulsing as darkness engulfs her.

The next thing she heard was the upbeat music that she heard when she was here in the first place, she awakes in this bed she was in, she lifts up the covers falling over her naked body, looking over she finds an orange jumpsuit all folded up in a neat stack with other types of clothing, her jump boots and portal gun besides it. The room was walled off glass room, with an orange portal as a door way, there was a shower right outside, Twilight got up and went through, she took her shower, washing all of the sweat and sex juices off, though she did not know why she was here.

"Hello twilight." Twilight was startle by GLaDOS's voice as twilight was enjoying her shower. "You passed out while you were doing your test. I didn't tell you to stop."

Twilight gulped realizing what happened. "GLaDOS I can explain."

"No need, you passed the test." Twilight stood there processing what she just heard. "I noticed that you were aroused while you tested, it distracted you, you never went to the bathrooms that provided for you to relieve yourself, I never understood why, and however it got me thinking, then designing, then experimenting, then wanting to find out something. How much you really wanted to be out of here."

Twilight blushed. "You stripped naked, sexually stimulated yourself, including almost endangering yourself, ever thought what would happen if those portals suddenly disappeared?"

Twilight gave it a quick thought, if those portals did, she would've been sliced in halve in theory, the portals closing on her, in huge amounts of pain, her organs spewed out, blood everywhere, her dying either frantically and desperately trying to put herself together, only being an impossible task without proper medical tools or even magic, or just realizing the impossible passing out, slowly dying as her face was buried into her own ass. Waves of fear wash over her as she kneels, but why would just portals just disappear? Could GLaDOS have that power and would kill her? Would she ever?

GLaDOS interrupts. "Besides that, I just wanted to make a creative scenario using portals, to create this act, and what I found was that you are indeed a pervert."

Twilight looks up, hurt and slowly getting angry.

"You intentions of getting out were not an issue, however as the test progressed you slowly enjoyed yourself, further degrading yourself in such an animistic behavior, and too be honest."

Twilight grinds her teeth.

"That is not a bad thing, you just went through your own desires and enjoyed your experience, and that in itself is not a bad thing. Besides how could you be hurt by a word that describes yourself perfectly?"

Twilight was shook her head. Not believing what she heard. "Because it's not that simple, Pervert means you are this....this....deviant who goes through this......sexual....fantasy.....in the most shameless act as possible."

"And why is that a bad thing? Why is something so good, feels so incredible such an evil thing?"

"It's not like that, you need to control your desires, so that you don't hurt yourself or others, our desires may end up controlling you if you let them run rampant. And besides it not a word you like to be labeled by, it is embarrassing"

"I suppose, then again, I really don't have such desires."

Twilight scowled, not believing the A.I. at all.

"get dressed when you are ready, there is still more testing to do miss sparkle, and so little time to waste, if only you were an insomniac, maybe we would get these tests to go by faster, just head to the elevator when ready. All dressed, it is improper to just run around naked, and you do need that portal gun after all."

Twilight was slightly angry, being insulted, called a pervert, knowing that maybe she had a point as she washed up, gets dressed, and heads out for more test, for more science, supposedly.
