Creeping through the shadows Synth scanned the dark corridor for any sign of life. So far the place seemed deserted and she assumed the crew were out enjoying the spaceport’s amenities, but best not to take any chances.
The upper levels of the ship were impressively sleek, but down here in the bowels it was far less refined. Pipes and valves creaked and hissed as she passed by, and the luxurious bedchambers she had glimpsed up top had been replaced by rooms packed with ageing control panels.
Still, compared to what awaited her outside, the ship’s dingy underbelly was a welcome relief. Life on the streets of Larin spaceport was never easy, but sooner or later you made enemies you couldn’t appease and in those cases the only hope for survival was escape. Synth hadn’t cared what ship she boarded so long as she managed to stow away before being spotted by the thugs sent to bring her in. Fortunately the ship’s guts provided plenty of hiding places, so all she had to do now was find one secluded enough to conceal her for the voyage.
Across the corridor a door stood ajar. When she scurried over to peek through the gap she was faced with a rusty room. Most of the walls were lined with ancient screens and dials, while an equally antiquated control panel stood off to one side. But it was the door on the opposite wall that caught Synth’s attention. It looked like it hadn’t been opened in years, which meant that nobody was likely to find her inside. With any luck it led to some kind of disused storage room.
Daring to believe she might have found her hiding place, Synth slipped through the door and zipped across the room.

‘Well, well, well. What do we have here?’
The purple-haired woman had been concealed by the hefty control panel. As she rose she unclipped a toolbelt, dumped it atop the panel and wiped a few smears of oil from her fingers onto a rag.
Shock hit Synth so hard she couldn’t formulate a reply. All she could do was stare at the beautiful crew member with bulging eyes, mouth hinging uselessly as all her hope evaporated at once. Despite the patch lashed over her left eye the woman’s stare bored into Synth’s soul. With her vibrant hair flipped over to one side she wore large platform boots that ascended almost to her knees, while the remainder of her person was encased completely in form-fitting latex. Much of her stomach was visible through a transparent portion intersected by lines of red, with more crimson accents decorating the latex over her thighs, breasts and shoulders. What was left was all black and boasted her lithe figure proudly.
Coming around to lean against the front of the panel the woman laughed at Synth’s stunned expression. ‘A stowaway, by my reckoning. You’ve got some nerve boarding us, girl. Most folks won’t come within two blocks of the Lady Sinister.’
Shit. How had she missed that? The Lady Sinister was the fear of most self-respecting men in the galaxy and the pride of the Mistress Order’s fleet, an organisation of the most brutal and sadistic hedonists, dominatrices and fetishists in the entire galaxy. Those who crossed them did not come off lightly. Of all the ships I could pick, why the fuck did it have to be this one?!
Clearly savouring the horror on Synth’s face the woman only grinned all the wider. ‘You don’t need to worry nothing, hot stuff, we won’t hurt you. Think yourself lucky you ain’t a male stowaway; you don’t want to know what we do to those.’
Synth wasn’t the slightest bit reassured. ‘So, what are you going to do to me?’

Twisting around, the woman retrieved something from the top of the control panel. Synth’s stomach dropped when she realised it was a gun. As she spoke she span the barrel and cycled through the weapon’s settings as casually as if flipping through the ancient magazines Synth had seen in museums.
‘Well, the way I see it, if you board our ship then you live by our rules. And rule number one on the Lady Sinister is that only members of the Mistress Order and their slaves are allowed onboard. So that means you have two possible options: join us or submit to us. Now, if you’d been caught by one of my crewmates then they would almost certainly have drained your brains until you were a giddy little fucktoy. But me, I’ve always enjoyed letting fate decide.’
With that she swung the gun up and aimed it squarely at Synth’s chest. ‘This is a nanite gun – you know what that means, right?’ Synth nodded: the rounds of nanite guns burst on impact, showering the target with millions of microscopic bots that would then proceed to follow their coding, which typically involved transforming their new host in one way or another. ‘I thought you might. Well, I’ve just coded half the rounds to turn you into a brainless sub and the other half to make you a fully-fledged Domme of the Mistress Order.’ The woman’s grin was raw mania as she gave Synth a wink. ‘Good luck.’
And then she pulled the trigger…

Synth was an hour into testing her new project when the stowaway was dragged into her lab. Reclined in the padded leather seat with her fat tits jiggling as her blank-faced drone tirelessly fucked her dripping sex, she took several seconds to notice she had company.
‘Found this one trying to hide among the oxygen generators,’ said Nyx, shoving the scrawny young man to his knees. ‘Figured you’d be able to make something useful out of him.’
The beautiful Domme was dressed in an iridescent latex catsuit that shimmered like a trapped galaxy, though Synth barely noticed her crewmate’s orgasmic attire. No matter what Nyx wore, Synth only ever saw the image of her aiming the nanite gun and grinning – the last thing she had ever seen before the weapon transformed her into a member of the Mistress Order. Even though her fate had been entirely down to chance, in the months since Synth had spent many long nights thanking Nyx for letting her join the crew of the Lady Sinister.
The miserable stowaway clearly didn’t know where to look. No doubt he had expected Synth to stop fucking her drone, but when she didn’t he tried his best to look away. Unfortunately for him since her transformation she had tinkered with her nanites, and now they emitted a constant cocktail of pheromones that made it impossible not to stare at her deliciously voluptuous body. As such even though he tried to stare at the floor, he frequently found himself glancing up against his will to watch the continuing depravity.
‘Oh, Nyx, you’re a lifesaver. He’s just what I need. I’ve already burned through all the test subjects I picked up at port.’ Both Dommes knew that when Synth said ‘test subjects’, what she really meant was the small army of men she had lured onto the ship with her irresistible pheromones. Mostly they were thugs and miscreants – the kind of guys nobody would miss – but when those were in short supply she was perfectly willing to seduce any man who crossed her path. Indeed, the drone currently fucking her was once a spaceport guard before she ensnared his mind and sapped away his brains to leave him empty and obedient.
Raising a brow, Nyx gave Synth a fiendish smirk. ‘Well, if you’re in the mood to really show me how grateful you are, you know where my cabin is.’ With that she turned on her heel and left the unfortunate young man at Synth’s mercy.
Perhaps in her old life Synth would have felt sorry for him. She knew a street urchin when she saw one, and she knew that when he stowed away he’d dared to believe the ship might carry him to a better life. But any empathy she used to have had been eaten up during her transformation and now all she could think was how adorable his helplessness was.
Still, she couldn’t deny being a little impressed.
‘You know I think you’ve set a record. We haven’t made port in almost three weeks and you’ve gone undetected all that time. No stowaway has ever lasted that long. Hell, I didn’t even last a day before they found me.’
The man looked up sharply. ‘You were a stowaway?’
‘Sure. Lucky for me Nyx gave me the chance to join the crew rather than serve it. The Mistress Order is always looking for extra members if you’re interested?’
The man recoiled. ‘Never.’
Even through the euphoric pleasure of her drone’s pumping cock, Synth managed to roll her eyes with exasperation rather than ecstasy. ‘No surprises there. I make that offer to every test subject and not a single one has accepted yet. Still, it’s your loss. Fortunately I have plenty of other uses for you.’
‘So, what are you going to do to me?’ Apprehension was written over the man’s dirty features, as well as a flash of regret as if he was second-guessing his choice to reject Synth’s offer.
For a few seconds Synth did not respond. Instead she took the chance to relish the wicked path the Lady Sinister had led her down. A few months earlier she had asked the exact same question while the cold fear of the answer roiled in her gut. Back then Nyx had seemed like the most terrifying creature in the whole universe.
Now she had come full circle, only this time she was the monster and he was her prey. And it seemed only fitting that she give him the same answer Nyx had once given her.
‘Well, the way I see it, if you board our ship then you live by our rules. And rule number one on the Lady Sinister is that only members of the Mistress Order and their slaves are allowed onboard. Since you’ve already declined joining our ranks, I’m afraid that means you’re now our plaything.’
‘No. Please, stars, no!’
Suddenly animated, the man sprang up and threw himself at the door. It didn’t budge. Only after several more attempts did he notice the palm scanner on the wall. Realising he could not escape without a recognised palmprint, he ran to the nearest workbench and snatched up the heftiest tool he could see. Or at least, he tried to. Yet to his horror his fingers simply passed straight through as if swiping at a hologram. Increasingly desperate he attempted the same with several other tools, all to no avail.
Panic engulfing him the man’s rational mind shut down and he did all he could think to do: curl up tight in the corner of the room.

During his hysterics, Synth had calmly shifted positions. Her drone was now sat naked on the padded seat, his grey-green jumpsuit abandoned on the floor. Synth had further disrobed too, and though her wet-look catsuit still clung to her legs and forearms her torso was entirely exposed. The net result was that the stowaway was forced to watch her tits bounce hypnotically as the drone drove up into her from below.
When she spoke, she had the same nonchalant tone as Nyx all those months ago.
‘Sorry, but you’re not the first subject who tried to escape. That’s why I keep all my tools out of phase. They only become solid in the presence of my touch, nobody else.’ One hand descending to toy with her clit she used the other to brace herself against the drone’s broad chest as she rolled her hips to take him deep. ‘Look, I know this isn’t what you had planned when you stowed away, but you should think yourself lucky. Before I arrived any male caught onboard was locked up in the Domination Chamber. Whenever any Domme felt the urge to unleash her wrath, she would disappear into the chamber and wouldn’t come out again until the screams of her slaves echoed from one end of the ship to the other.’
Synth’s lids fluttered as she continued, her voice slightly breathy under the pleasure of her obediently pumping drone.
‘But I’ve made a few changes since I arrived. See I’ve always had a mind for invention, and though back home I had to make do with scrap and garbage, the Mistress Order can afford anything I could possibly desire. Now there’s no need for the Domination Chamber because I’ve designed an entirely new breed of slave. They never complain, they never try to escape, and their only purpose is to satisfy the desires of their goddesses.’
Leaning to one side, she gestured to the drone. He was utterly oblivious to the stowaway’s presence, his gaze instead fixed on Synth. Despite his blank features, in his eyes burned a lust so fierce it was clear he had utterly lost his mind to it.
‘Isn’t he perfect?’ Synth cooed, caressing his cheek with the back of her fingers and leaving twinkling trails of pussy nectar on the skin. ‘He was my first success. I burned through dozens of test subjects before him, but he made all the failures worth it. I actually managed to rewrite his psyche from the foundations up. Now not only does he follow every command without question but he actually enjoys it too. Just the act of obeying feels as intense as the peak of orgasm – and since he only exists to obey, he is locked in a permanent state of ecstasy. Sure, his true psyche has no doubt been torn to shreds by now, but if you ask me it’s still better than a life in the Domination Chamber. And the other Dommes seem to agree – almost every crew member has at least half a dozen drones of their own, from sissies to sluts to bulls to bimbos, all manufactured here in this lab.’
Without warning a manic glee lit up Synth’s pretty face. ‘And now you get to join their ranks! Just think of it: a life of endless pleasure. Every second of serving the Mistress Order will be like all your fantasies made into reality. Better yet, you’ve already met your new owner: Nyx!’ The stowaway blanched but Synth simply chuckled. ‘She’s been a little cautious about trying out my drones – says she prefers ruining her subs the old-fashioned way – but I’ve managed to talk her round. She’s even made a request of what type of slave she wants. Isn’t that exciting?’
Still unable to tear his eyes from Synth’s undulating body, the stowaway looked like little more than a heap of rags. While she spoke the fight had visibly drained from his limbs and even his shaking had stopped as the numbness of hopeless resignation set in. Even so, some morbidly curious part of his mind needed him to ask the question.
‘What slave does she want?’
Synth’s smile was one of childish delight even as her answer made the stowaway’s heart drop. ‘A futa one. I’ve never made one before, but the nanites I use to transform my subjects are perfectly capable of doing it. She says she wants a slave who can satisfying any possible craving, so who better to do that than a drone with a cock, a cunt, a deliciously spankable ass and a pair of big fat tits to complete the package.’
Slowing her bucking hips, she beamed down at her captive with an expression that was almost affectionate. ‘You’re going to be my finest creation,’ she sighed. ‘And you know what they say: no time like the present.’ And with that she destroyed the stowaway’s world with a snap of her fingers.
At no point during his time in the lab has the young man thought to look up. If he had, he would have found the ceiling festooned with shifting pipes and cables, like a bed of snakes slithering across the roof. Given how many of her subjects tried to escape at first, Synth had quickly learned that it was much easier to let her machines do the work than trying to wrestle them into submission herself. As such she had designed the pipes so that they could reach anywhere in the lab at her command.
Now one of those pipes came hissing down towards the stowaway. Rather than solid material it was instead formed of an iridescent black goo which is what allowed it to stretch to even the furthest corners of the room, and it was tipped with a glistening sphere of the same material about the size of a fist. As it descended the sphere unfurled like a blossoming flower bud.

The stowaway barely had time to register the pipe before it struck him. Latching onto his head the petals folded around it, stretching and spreading until they had completely engulfed his skull. A heartbeat later and the gooey mask was flooded with pre-coded nanites that immediately set to work corrupting him into the newest slave of the Mistress Order.
As his body writhed and his muffled screams filled the lab, Synth was reminded just how erotic she found the chance to watch her creations take shape. The sight of the stowaway’s transforming body sent her arousal through the roof and all at once she was possessed by the urge to ride her drone harder than her present position would allow.
Rising up briefly, she quickly pivoted around and sank onto the drone’s waiting cock once more. ‘Fuck yes,’ she groaned as he pumped up into her waiting hole. Her tits bounced against his face and she gripped his shoulders hard. ‘Oh fuck yes! Don’t stop. Pound me until I’m howling.’
Just before mania overcame her Synth gave a last glance over her shoulder. Already the nanites had eaten away the stowaway’s clothes and a pair of plump breasts were swelling up from his bare chest. ‘Don’t mind me, I’m just going to put my drone through his paces for a while. It can take a few hours for the transformation to complete, so we’ve got plenty of time to kill. Don’t go anywhere.’
Then, giggling at her own joke, Synth turned her back on her latest experiment and proceeded to let orgasmia consume her as the stowaway’s delightful screams drew a slutty smile over her face…
Thanks for reading!
There are a few things to say about this one.
First off, just a quick note to highlight the images I used for the first half of this piece. The model in those images is Octokuro. At the time I released the original version of this on Tumblr, Octokuro was a model who did not partake in pornographic content. As mentioned many times before, my ethics in how I choose the images I include in my stories have evolved over time, and so under normal circumstances I would never have reused her content now. However, in the time since the original, Octokuro has shifted into explicit sexual content. Granted the images used here were taken before that transition, but overall I felt comfortable to reuse them not only due to the change in the nature of her contemporary content, but also because this story does not use her images to support an outright explicit scene. Instead, that task is left to Karlee Grey, whose work I have used many times on this blog and will doubtless do so again.
The more important note for me personally is that, as emphasised in the tags, this story is a reader request – and a very overdue one at that. Back in 2023 I received a comment from one gapril2063 asking me to update and expand on this story from my Tumblr portfolio. At the time I hadn’t revisited any of those Tumblr pieces and to be honest I didn’t really think there was that much reason to do so.
Of course, that all changed once I started rewriting those stories for this blog, at which point I knew I had to revisit this one. Not just because I was interested in exploring a sci-fi theme, which doesn’t often crop up on my blog, but also because I wanted to write this as a thank you to gapril2063.
Truth be told, I don’t even know if gapril is still reading my work. They used to be a regular commenter, yet the last comment they left is approaching two years old so for all I know they have moved on. If that is the case, then I genuinely wish them the very best in all they do. But either way, I also want them to know how very grateful I am for their support of my work over the years.
Arguably gapril has played a more defining role on this blog than any other individual reader. They inspired my first reader requested story, which subsequently developed into the A Neighbourly Favour miniseries, a storyline I still love to this day. Their own username contributed to the development of my now-annual Gaypril slate, which was almost scheduled in for May or August under frankly far worse titles. And for me the most meaningful thing is that they were the first person to ever comment on my blog. I genuinely appreciate the presence of everybody who supports me by reading my smutty musings, but I think I probably speak for all writers when I say that hearing our readers put that support into words in the comments is a buzz unlike any other. The fact that gapril2063 was the first person to give me that buzz so soon after I first started this deviant journey – and that they followed along on that journey for so long – will always be important to me, and so this piece is dedicated to them.
So, to put it very simply: thank you gapril2063. And if you are still here after all these years, I truly hope it was worth the wait.
