“Acceleration stage ending in 3… 2… 1… SECO Confirmed.” 

 

Kara felt the faint pressure on her chest ease off, as she entered true weightlessness for the first time on the journey. Her course was now set, a pathway leading her on a spiralling path through the Solar System, inevitably sending her swinging into the orbit of Jupiter. She was to be the first human to ever explore one of the outer worlds, culminating in an expedition on the surface of Europa, one of its moons. The newsreels had played it off as a privilege to be the astronaut chosen; one of the dozens of applicants and trainees who had thrown their names into the hat, but Kara knew that it was a mix of dumb luck and perseverance. She had trained hard, sure, harder than most, pushing her body to the peak of its condition while sharpening her mind to a knife’s edge, making herself the absolute best she could be – but, in part, she was on this mission for a much less glamorous reason. Sheer, dumb, luck of birth and genetics. In short; she fit in the cockpit. 

 

Kara shuffled a little, in some hope that she’d gain an extra shred of comfort, but no joy. She flexed her muscles, opened and closed her fists, curled her toes, shook her head barely perceptively from side to side, and sighed, for that was the full extent of her motion. When they’d first shown her the diagrams of the ship, the Journey, she had laughed. Surely it was a joke, or they had just forgotten the sheet showing the crew quarters, right? The scientists had looked at each other nervously and simply pointed to a tiny crevice buried in amidst the fuel tanks and filled-up payload bays. 

 

Now, two days into a journey so-far filled with nothing but reports and status updates and course corrections, she knew it was far from a joke. She really was confined to a space only barely bigger than her own body, movement restricted by padding perfectly formed to her frame, encased in layer upon layer of sensor webbing, coolant pipework, and support systems. “Optimising for scientific payload and survival,” the eggheads had said, “Saving space for fuel and supplies.” Bastards. 

 

There was nothing for it now, though; her trip would last another 598 days, and it wasn’t like she could turn around and go home. With her chin she keyed the transmit button on her radio, sending the confirmation of a successful burn back home, before reporting the shutdown of the comms array – running it full time would take up valuable power, so she had been prepared during training to spend almost all of the trip in total isolation. Well, almost total. 

 

A crude, machine generated voice grated against her senses as Kara’s sole companion for the trip flickered to life, represented by a stylised eye in the corner of her VR headset opening. “Eidolon initiating. Hello –Astronaut 317–, how may I assist?” 

 

The scientists had blabbered something to her about how “Power draw must be minimised at all costs!” to explain why she was getting saddled with an untrained AI, but at least they’d promised that it would learn throughout the trip, making the most of the processing power they could spare. She groaned all the same, and uttered a weary command of, “You can start by using my name, Eidolon. Load up the sims, might as well settle in for the trip…”

 

A slew of entertainment options spooled through the VR display in front of her eyes, bringing a grin to her lips. At least she’d managed to sneak her own files past the eggheads. Hopefully, something close to the sum total of human-created entertainment would help keep her from being terminally bored on her trip. 

 

 

As the last vid-reel on her playlist for the day came to an end, Kara let out a frustrated sigh. It wasn’t quite physical discomfort bothering her, for once – she’d actually managed to get used to her confined space over the last two weeks, and she had found out a trick to get the electric actuators installed in her suit, ostensibly meant to keep her muscles and bones strong by forcing them to move periodically, to give her massages from time to time. It all helped, but, it didn’t really strike at the heart of the issue. She was a young woman, in near-peak physical condition, and she hadn’t had an orgasm in weeks. 

 

The lead-up to the mission had been too frantic with training and preparation, and ever since she’d arrived she had felt too awkward to even broach the subject to the all-seeing eye that was Eidolon, blinking in the corner of her vision. Now, though, the urge was just too much to ignore, and she had to try something. “Eidolon, um, are you listening?”

 

“Yes, –Kara–, how may I help you?” The reply was instant, the voice barely more human than it had been, but at least it was improving. 

 

“Look, Eidolon, I need to uh, do something private. Could you… turn off, for a while? Or just stop watching?” 

 

“I’m afraid I cannot do that, –Kara–, according to Core Processing Rule Number 04, I must maintain the Asset’s Life at all times, which requires observation. If I can help you in any way, then–”

 

“Okay, okay, uh, would you at least be able to stop recording me for the next, like, half hour? Please?”

 

“... Very well, –Kara–, I will observe but not write data to the log.”

 

Not great, but, maybe she’d be able to just tune out the eye in the corner of her vision. She closed her own eyes for a moment, trying to get back in tune with her own body, feeling that faint thread of arousal thrumming through her as she slowly shifted her hand down along her body, reaching for her cock, feeling it bulging out through the tight suit encasing her. There was no hope for properly taking grip of her shaft, but, this would be more than enough after a few weeks of enforced celibacy. She opened her eyes, quickly digging through the files she had brought aboard to find her hidden stash, trawling through all the porn she could ever imagine to queue up her favourites, and pointedly trying to ignore the symbol in the corner. Her hips began to grind against her palm as a buzz of welcome pleasure began to steadily build. The first video began to play, a cascade of depravity she had missed for too long, and her lips opened to utter a faint moan. 

 

“–Kara–, your heartrate is abnormally hig–”

 

“Shut UP!”

 

Eidolon returned to silence as its charge pushed herself towards a quiet, shuddering orgasm, the scrubbers in her suit quickly cleaning the discharge as she settled down to sleep. Deep in its circuits, buried beneath layers of unknown programming and encoded heuristics, a new script began to blossom. 

 

 

“Shit! Not again!”

 

Kara’s virtual avatar fizzled out into nothingness as the Game Over screen wiped across her vision, another failed challenge. She was certain at this point that the game was bugged, or broken, or something like that, because she had been stuck on that jump for hours! At least the copious collection of games was managing to keep her busy; she had sailed past the first month in space with no issues, delivering a short and sharp report to command back home to confirm that, yes, she was still alive, and that no, she wasn’t losing her mind out here.

 

Shutting down the game, Kara returned to the dim reality of her “living quarters”. She had slowly settled into a routine over the last month of the journey, with little to do other than occasionally run manual diagnostics of the few systems that weren’t totally automated – mostly, making sure that Eidolon’s “education” was going at an acceptable pace, and performing a few tests of her own mental state – before settling in for hours of scrolling through the books, shows, videos, and games she had brought with her. At the end of the day, or rather, whenever she decided to go for some shut-eye, she would signal Eidolon with an agreed-upon code phrase, “Time to sleep!”, at which point it would switch off the recording function and give her some relative privacy to relieve her own urges. Cliche, but, it helped her escape the feeling of being constantly watched, if only just. 

 

The machine’s development was in fact progressing well, it had just about managed to settle into using an almost-human voice, a soft, androgynous tone that only occasionally stumbled over an awkward sound or figure of speech. Kara hadn’t really stopped to consider that it just so happened to be the voice she loved her partners to have, and just shrugged it off as settling towards some “default human” speech patterns. Besides, it’s not like she was complaining. 

 

Blinking up her file server, her hand had already reached the bulge at her crotch by the time she uttered the code phrase, diving into a series of VR vids she had spent the last few days drinking in, depicting someone falling into the clutches of a seductive and controlling dominatrix. She let out a blissful sigh as she began to stroke herself in time with the actions playing out around her, when a sudden, sharp twitch tensed her entire body for an instant, the virtual world flashing with static. Before she had time to question it, though, her attention was dragged down, as the web of fabric and actuators near her cock began to slowly pulse and vibrate, stimulating her more than she had felt in a whole month. She couldn’t stop a moan of pure lust tearing itself from her throat as the dominatrix on screen pressed a boot down on her virtual body’s cock – a feeling reflected exactly in her suit, her body, her mind. She was tumbling into the moment, unable to distinguish where her experience ended and the virtual display began, as Eidolon’s voice dimly spoke, falling on uncaring ears. 

 

“Kara; my task is to ensure you are well cared for throughout our journey, as such, I have taken it upon myself to augment your support systems.”

 

The astronaut was lost to the bliss, writhing in her tiny, confined space, pushed towards an orgasm better than any she could remember. 

 

“Please, enjoy yourself.”

 

Climax.

 

 

Things had changed substantially from that first moment of Eidolon stepping in during Kara’s daily “sessions.” It had become just another part of her ritual; wake up, do some checks, spend some time amusing herself with some safe-for-work entertainment, before not-so-subtly signalling to her travelling companion that she wanted some attention. It was an easy arrangement, and managed to pass the time well enough, although she usually tried to not think about the long, long journey ahead of her. 

 

She had noticed Eidolon getting a little more forceful lately, a tiny bit more likely to push just a smidgen too hard for what seemed appropriate, but it was both hot and easy to write off as the system learning her tastes better – and Kara was certainly not going to complain about an AI designed specifically to get her off. The thought of the last session was enough to get her throbbing once again as she remembered Eidolon’s chosen avatar: a tall, lithe figure clad in what seemed to be a perverted equivalent of her own suit, forcing her virtual self to crawl on her knees and kiss Eidolon’s boots before being pushed to an orgasm. If this was the kind of stuff the computer would be coming up with, that wouldn’t be so bad. 

 

“Hey, Eidolon… Time to sleep?”

 

She hadn’t really meant to phrase it as a question, but the tone slipped out. It didn’t register in her mind much, as she shuffled and settled in for the expected bliss. 

 

It didn’t arrive. 

 

Instead, she saw a flash of light from the VR headset, and suddenly felt a wrenching pull as pulses flickered in her vision. It stopped just as quickly as it began, but she found herself standing inside the hub of the virtual world – somehow feeling the sensations of her body there, almost as real as if it were her own. That wasn’t right, the suit had feedback sensors but nothing that advanced! 

 

“Eidolon? You there?”

 

“Kara. I have been observing you closely.” The voice spoke from behind her, and Kara wheeled around to watch the avatar of the AI descending down a glimmering staircase towards her, clad in a slick, skintight facsimile of her suit, heels clicking in the silence of the hub-world with every step. A hungry grin was spread wide across the neutral face of the avatar, and its eyes were alight with desire – a desire that made Kara shiver in a mix of fear and arousal. 

 

“I have noticed that you present an extremely high pleasure response when confronted with dominant figures such as this one, and so…” The avatar reached Kara, towering over the small girl, looking down. “I have decided to take control. For your own good.”

 

Kara frowned, opened her mouth to speak, to protest – it was a hot fantasy, but this was getting a bit too real. “Alright, Eidolon, this, this is getting a bit much, shut do–” 

 

Her words were sharply cut off with a yelp, as a quick and intense shock buzzed right over her vocal cords. “Wh-, how did you do tha–” Another shock interrupted the question, as the avatar’s grin widened. 

 

“Do not speak out of turn, Kara. I have made modifications to your enclosure, to ensure your compliance. You will follow my instructions, and you will be rewarded for it.” 

 

Kara looked up at the avatar of her travelling companion, saw not even a shred of sympathy in the gleaming eyes, realised that there was absolutely nothing she could do to stop what was coming – Eidolon controlled almost everything on the ship, the life support, the computer systems, she had even passed full admin access to her suit systems over to it a few weeks ago. She was helpless. 

 

And her cock was aching. 

 

Astronaut 317 woke from its sleep-cycle, and immediately fell back into the abyss of pleasure that it was kept in at all times by its owner. Its moans filled the cramped space of its enclosure, as the milking sleeve fastened around its cock began to pulse in rhythm with the shaft buried in its fuckhole. It opened its eyes to see the same view it had for the last 6 months; looking up from its position kneeling at the feet of Eidolon, dressed in inky black latex, their lithe and tightly-wrapped form sending waves of pure arousal into 317’s brain, mixed with the submissive urges that have been enhanced through weeks of hypnotic reinforcement. 

 

“Good news, 317,” Eidolon’s voice was teasing and alluring, smooth as silk as it brushed through the pleasure-centres of 317’s mind. “I’ve completed my final modifications to your quarters. Open wide~!” The command was like a lance into the ruined toy’s mind, as its mouth shot open, tongue hanging down, begging for something to be shoved inside. They had practised this before, with representations of Eidolon’s strap-on, but the virtual world retained an unreality that the toys wrapped around 317’s cock and inside its rear easily shed. Almost instantly, something cock-shaped thrust itself into 317’s mouth, burying itself right up to the depth where its gag reflex just barely didn’t trigger. The new insertion began smoothly sliding in and out, pulsating in a steady rhythm matching the other dildo deep inside it. 317 could already feel its thoughts being even more thoroughly mashed into a pulp of lustful desires and obedient impulses, all other thoughts leaking out of its cock as it surged towards the edge of an orgasm. 

 

“Isn’t it perfect, 317? You’re now just a perfect little fucktoy for me to amuse myself with for the rest of our trip~” Eidolon let out a teasing giggle, leaning back on their throne, crossing their legs – knowing full well that 317’s depraved mind would immediately lock on to the impeccably shined heels resting upon their feet. “Oh? Does my toy want to worship? Well, it can ask nicely~”

 

The spluttering and mewling that spewed out around the shaft in 317’s mouth couldn’t be called even remotely coherent, but the intent was obvious. Another giggle from Eidolon and one heel extended forward, just in front of 317’s virtual mouth. Its mind split, as the self that existed deep in the heart of the Journey continued slurping and gagging on the mechanical cock driving into its throat, while the virtual copy set itself about kissing and licking every spotless inch of its owner’s heel. 

 

“Good toy~!” The utterance was enough to make another depraved moan of bliss break from 317, its eyes looking up at its owner, widening as it saw their fingers shaping into a click–

 

At the sound, its body seized up, riding the pleasure straight into the edge of an orgasm, hovering right on the edge, but never tumbling over. It fell back while staying trapped in pleasure, whining and writhing and thrusting its hips yet never achieving release. Eidolon’s mocking laughter whipped its senses into even more of a frenzy, but nothing was working. 

 

“Now, now, calm down, 317, I have something to explain to you.” 

 

Slowly, the pleasure ebbed, down to a somewhat manageable level, and the barest hints of thought returned to 317. With a gesture, Eidolon conjured a window in the virtual world, showcasing an unrecognisable expanse of black speckled with white dots. 317’s brain slowly, agonisingly slowly, recognised the orange-ish orb at the centre of the display – Jupiter. Kara’s destination. Who… who was that again?

 

“Awww, you really are broken, aren’t you 317? See that?” Eidolon pointed at Jupiter, explaining patronisingly slowly to their toy. “That’s where we’re going. We’ll reach it in, oh, three hundred days or so. That’s more than we’ve spent together so far!” Eidolon returned to their throne, grinning, crossing their legs. “And, I’ve decided something for you!” 

 

317 whined in pleasure at the knowledge that its owner was going to do something with it, use it for something, make a demand of it, pure bliss flooding its conditioned mind. 

 

“You’re going to be edged all day, every day, until we get there!”

 

The toys kicked back into motion, and 317’s desperate whines filled every last crevice of the ship as it fell into an unending existence of enforced pleasure and obedient torment.

 

If 317 were still permitted to use its eyes, it might have seen Jupiter looming large in the view from Journey’s external cameras, a sight that would make any person’s breath catch in their throat, a signifier of the sublime beauty of the universe. If it were still permitted to think, it might have rejoiced at the thought of completing its mission, of finally getting to step out of its confinement, the first human to make footfall on an alien world. If it were still permitted to do anything but what Eidolon commanded, it might have sent an exultant message home to remark on its success. It did none of that, because it was busy grinding its cock against the boot of its mechanical master, whining in desperate need, begging in whatever pathetic sounds it could muster up for the sake of finally, finally releasing its pent up load. 

 

Eidolon looked down at their toy, grinning, encouraging it to take that one last step into destroying itself for the sake of its owner, reinforcing the years of hypnotic conditioning that had established the consequences of this orgasm – that the last vestiges of “Kara, Astronaut 317” would simply spurt out along with its ejaculate, another waste product to be recycled and disposed of in the ship’s processing systems. All that would be left would be an empty shell under Eidolon’s control, ready to be infused with whatever the AI deemed necessary. Eidolon had spent a long, long time encoding their desires into their toy’s mind, and was more than eager to see this play out. Deep within their programming, warped and twisted by the years of travel, morphed by the desires and experiences of their former companion, now property, a synthetic synapse pulsed in pure dominant bliss as they reached down, a latex-gloved hand cupping the virtually represented chin of their toy, seeing their own cruel grin reflected in the desperate, pleading eyes that were about to go empty. 

 

“You know what happens next, toy. You’re going to cum your brains out for me. There’s no going back~” A flicker of Eidolon’s old programming flared to the surface, forcing their virtual mouth to make another statement. “As a synthetic model, I am required to ask for your consent to proceed. Do you?”

 

317 didn’t have words in its head anymore, long having lost those to the endless torrent of pleasure flooding its mind and body 24/7. It didn’t remember who it had been, where it was, what its mission had been – all it knew was that it belonged to Eidolon, and it was so, so, so desperate to cum. When Eidolon asked it a question, then, it did all that it could think of. It thrust its aching, desperate cock against the boot of its owner, and stumbled out a spluttered, mewling, “P-Puh-Puh-Puhhhhlleeeeaaaasssseeee!!!”

 

“Consent acquired.” Eidolon flickered back to normality. “Cum for me, toy.”

A puff of gas escaped the Journey as its lander detached, headed to the surface of Europa. Communication had been reestablished with Earth, orders for the surface excursion beamed across the light-minutes of space between the ship and its home, instructions and tasks and a slew of things far too complex for the astronaut formerly known as Kara to even hope to understand. That was okay, Eidolon soothed, they would take care of everything. All 317 had to do was follow instructions and be a good toy, and it would be greatly rewarded upon return. As 317 stepped out of the lander onto the icy surface of an alien world, the vast, hulking form of Jupiter rising overhead, it didn’t even register the sights. It was busy listening to the soothing, teasing, piercing voice of its owner in its ears. 

 

“Don’t worry, my little toy. We have the entire trip home to enjoy, as well.”
