Master Chief, John-117, dropped his weapon as he reached the Covenant cruiser's mainframe room. His mission, hunt down the derelict Covenant corvette cruiser, dispatch anyone inside who formed any resistance then retrieve any usable technology, was now complete. His right hand moved behind his head, then took the interface chip containing his companion AI, Cortana, from his helmet slot and slid it into the slot on the computers in front of him.
The ship's mainframe computer booted up and the hologram representation of Cortana, a curvaceous purple shaded woman with short hair and eyes that always looked at John with an almost too human fashion, formed itself from the computer's interface. Even John-117 could not deny that the hologram before him was alluring, despite its inhumanity. If she were real she would be quite a catch he thought to himself from time to time.

Her right hand moved up, her pointer and middle finger lightly touching her forehead as terrabytes of information were processed and said "Ok Chief. All relevant Covenant tactical data indexed. No life signs detected on board. What d'ya wanna do with these files?".
The super soldier looked shrugged, the processes going on inside her still a mistery, and said "See if you can find anything of use"
Cortana touched her head once more as her left hand made motions through the air as if to flip the pages of a book that wasn't there..."Junk...junk...junk" she said as she searched through the files. "Nothing we don't already have"

Master Chief sighed in relief before removing his helmet. His mission was now complete, Cortana motioning around to activate the beacon and informed John they now had to wait a few hours for extraction. It was these times of solace when John always contemplated his life's personal goals. Was it these quiet moments what he fought for? Was it for a promotion? He never came to an answer that would satisfy him.

"Here!" exlamed Cortana. Master Chief regained focus and looked at her. "What did you find?" he asked.
"Hmm....the encoding is different. Seems to be a different kind of file...not tactical data. Communications upgrade? Are they finding new ways to transmit tactical information?" she muttered to herself, still trying to decipher the code that rushed in front of her.
"Coms upgrade?" asked the Spartan.
"I dont know..I cant tell unless I execute it and run the processes written. Its very well encrypted" she said.
"Nothing gained..." he said, nodding to himself.
Cortana placed her hand against her forehead once more, then began absorbing the data, eager to see what kind of upgrade the covenant were storing.

She grunted as her head twitched to the side, and immediately, her holographic representation began distorting, and her image disappeared every few seconds as she moaned in pain. The program's code was now mixing with hers. Data being rapidly written onto her coding. New commands and processes were simultaneously being executed, almost overloading her programming in the process. As each individial bit of information executed, Cortana recognized the language it was written in. The data stored in the computer was stolen Forerunner data.

"Are you ok?" asked the Chief, his entire body immediately shifting towards her in concern.

After a few minutes, her image was stable again. No more interruptions. But something was different with her holographic figure. Her skin tone shifted towards a darker purple and the textures displaying her body more defined. Her breasts seemed to jiggle more realistically as she moved around. Her body was now more human. Her breasts had nipples, beneath her pelvis was her slit. Master Chief had not seen a nude female in more years than he could remember. As she moved around, the Spartan noticed her more defined and sexy body. She seemed to be a hologram not that of an AI, but that of a human.
"Woah! W-whats happened to me?" she asked with a fearful voice, inspecting her body as she stumbled around. “I FEEL....different. S-something's wrong John..the program..." she tried to exclaim, her body trembling as her right hand started to move involuntarily down beneath her pelvis and to her pussy.

This was Cortana as John had never imagined he would see her. She was on her knees, rubbing her clit as she moaned in pleasure. She seemed to be completly horny. Was it the upgrade? Master Chief was not displeased and did not voice any concern. He felt himself aroused as he watched his faithful AI pleasure herself.
As Cortana moaned from her self-inflicted pleasure, Master Chief began to remove his armor. This was, by far, the craziest thing he had ever done. Trained a lifetime to be as disciplined as he could and could not believe himself. However, the sight of his secret lust fingering herself and the sound of her moans on the ship's speaker system was overwhelming. He stripped just enough to uncover his erect cock. This was a once in a lifetime chance for him. After all the death and pain he was burdened with, maybe this was his small reward.

Cortana may have been too busy pleasuring hesrelf, but not too much to notice her companion's large cock. Her process systems were affected even more as this simulated her more and more lustful human thoughts. Her pussy was dripping, and her fingers were wet. She began to lick her hand clean as she rubbed her large tits with her other.

Master Chief couldn't help himself anymore. He began rubbing his cock slowly at the base as the "woman" before him moaned in newfound pleasure. She was too excited getting off on him masturbating for her, and she began to dig in a few fingers inside her pussy, letting off a few moans as she penetrated herself. It felt so good to her, and Master Chief was now pumping his cock rapidly as she screamed in ecstasy. She needed more, much more pleasure, and so she used her other hand to insert some fingers inside her new asshole as well. It was too much, and neither of them could control themselves.

Master Chief was stroking his cock as fast as he could, and Cortana's screams of pleasure kept him going, his cock dripping precum. He was gonna cum soon, but not before she did.

Her pussy was dripping, and she was about to give in. Her face seemed to be completely flushed. Her head shifted side to side as her body trembled and her fingers rushed in and out of her.
She yelled so loud as this was her first experience, and she was so horny. It felt so great. Master Chief had not masturbated, ever, so their lust for each other seemed almost equal.

After a long session of pleasure, she couldn't take it anymore. She had given in. She let out a final moan as her pussy began squirting out her juicies. This was her first climax, an experience she only theorized about. There was so much of her juice beneath her. It seemed real, and it was all over her thighs. Her pussy was completely soaked. For the very first time, she felt. And she felt amazing

Master Chief gave in after seeing how much she came. He aimed his cock for the hologram, and let out multiple shots of cum that sped towards her hologram, trespassing her and hitting the mainframe's wall.

They were both tired. Cortana seemed to return to her regular self, but the experience stayed with her, as it did with John. She found herself thinking about the experience, feeling a bit excited again, and her body transformed to her sexy human self again before reverting. And it was then that she learned to control her new “upgrades”. She looked in front of her, the Spartan resting his back against the wall as he nodded off a bit.

She found herself lacking concentration as the Chief rested. No military strategies. No covenant tactics. Nothing that did not have to do with her love and lust. All she could think about....obsess about, was him. John-117. Master Chief.....
