Full Species Replacement

It's a liberating feeling. Of course it didn't start out as such. Oh no, liberating was the opposite of what I would have called it. The first time your arms and legs are restrained is terrifying. But over time you learn to appreciate it. Once you have managed to let go of that baggage, those instincts, there is freedom. It takes time to build that trust with someone. But once it's done, I found comfort knowing I am always in good hands.

I'm laying on my chest on a specialist medical chair, like something you'd find in an operating room or dentist's office. Arms and legs spread out, as to maximize accessibility to my skin. Head secured towards the floor inside a hole in the matte. I can't see any of my surroundings, but that's not unusual. Like I said, you get used to it. Actually, nowadays I prefer it that way. I don't know why I'm here again but that doesn't phase me particularly. Probably just some maintenance. I don't see the room but I'm already familiar with it. It's a mixture of a surgery room and a laboratory. The bright white ceiling lights can be seen reflected in the glossy smooth floor.

The door slides open and in walks my guide. I can tell just from the footsteps. The frequency and sound characteristics. Not sure what makes them distinct. Consciously I couldn't describe to you an algorithm to detect them.

"Today is your big day sweety"

Big day? What is she planning?

"You've done very well on your personality test. I must say I'm proud of the results. Of both of us! I know we had hard times and believe me, I was suffering with you, but it was all worth it in the end, don't you agree?"

I don't remember what she's talking about. Was there ever a time that was hard for us?

There's not much point in asking. Not like I would be able to anyway. After the throat operation they did on me yesterday I have not been able to talk yet. It's weird to be in that state without any physical gag. That is a new one for me

"And that ending is today."

Personality test? Is she talking about the dream surveys we've been doing lately?

"Your test results were very revealing. Again I'm proud that you want this too. These dreams of yours... they're my dream too. I think the team has found a living arrangement that will make the both of us very happy indeed"

Okay so it was about the dreams. I don't care what it is she is intending. As long as it brings her joy, I am glad to do it. I will always be in service to my beautiful princess. Oh that word again. I don't know where it came from. She's never called herself that. I just associated that word with her one day. Not sure where it came from, but I liked it when it came into my mind so I'm sticking to it. Princess' special little one.

"You will undergo a very new and exciting procedure. This new body is going to change your life forever. Oh I can't wait! Doctor, please, let's begin!"

My guide's, my precious princess' footsteps are drawing closer before I feel a needle injection in my back. Did she do that herself? She always leaves this to the staff. This is truly a special procedure if she is going hands on! Even as little as a needle poke, coming from her, means the world to me and more. A poke from her highness! Although I couldn't feel much before from being restrained, I could still tell that my entire body is getting numb.

I hear some kind of saw or drill for a few seconds. Not sure what that was about. The sound is frightening for sure but I didn't feel them touch me. I see shadows moving on the floor. The shadows cast by my spread out arms are separating out left and right. Did they... remove my arms? Have my arms just been amputated? I couldn't feel anything. I swear they're still there. They must be. I can feel myself opening my hand, can't I?

Something is strongly pushing into both sides of my torso, but far higher than is normal. Something is getting screwed into where my arms used to be. So it is true then. They're plugging my open stump shut. Why was there no blood dripping on the floor?

Whatever they're doing up there, I remain calm. I know that my guide wants this. This is going to fulfill my dreams. Whatever those were... Don't remember any of them but apparently there were many survey tests. It's going to make her so unbelievably happy. Endlessly happy.

The saw again. I can already guess what they're about to do. I couldn't see a shadow this time but trying to wiggle around my butt, I knew the same had just happened to my legs. And there's the screws. Not a minute has passed.

I do wonder what she wants to do with me if I don't have any limbs, but I must admit that I've not been using them much anyway lately. After a few months in the vault you forget that you even have them.

Another injection. And everything went dark

I find myself waking up in darkness, lying on my back. The floor is soft, cushioned and warm. I try to feel around before I remember that I no longer have any hands. I shuffle about with my torso and can hear from the characteristics of the echo that I'm in a really small room. I try to lift my torso, surprisingly that still somewhat worked without legs, and bump my head into the cushioned ceiling just a few centimeters above my head. I shuffle left and right and quickly find the bounds of the box. Back to the box again? A smaller one this time though as I fit into a much smaller footprint. It's a new sensation for me. Lying there unrestrained but still unable to move. Is there more to come or is that it? Not much to do so I slowly drift to sleep.

I awake to a bright light that takes up my entire vision. I try to look around but everywhere is the same solid bright white. I'm still lying on the floor. How is it this bright? Slowly the lights dim a bit and I start hearing the subtle quiet rushing of a quaint forest waterfall. Princess always treats me well like this. I rest my head back on the floor. The bright lights quickly shut off, same as the sound, back to total darkness. I guess that was just to wake me up. After a few hours I fade back to sleep.

4 days later

Is this the new living situation she spoke of? Lying in a box all day with no stimulation apart from 2 minutes of waterfall sounds? It's not as mind numbing as the vault but, to be honest, I expected more. This is not her style. More is to come for sure!

9 days later

I wake up in a bed. A bed?? I've not been in a bed for... Uhm.. Have I ever been in a bed? It feels familiar. I've felt beds before, but I can't recall any nights sleeping in them. It's a medium sized bedroom, decorated in an exciting range of style from generic to ordinary. It's quite impressive how featureless a fully furnished room can be.

I sit up from the bed and walk towards the mirror... woah one second! I am walking?! On legs. My legs! And my arms! What the hell is happening here, what did I see those weeks ago? Did I dream all this? Okay back on track. The mirror. Yup, all body parts all there.

I hear the handle of the door. Didn't even notice there was one. In comes princess. Instinctively I step back and kneel, looking down.

"Oh I'm so glad you're well!"

"Please, look up. I want to see your face"

I follow

"Nod if you can see me"

I nod

"How many fingers?"

I try to speak, but to no avail

"That's the right answer"

"Your throat still needs to heal a bit. Please enjoy the rest of the day here. I'll check in with you momentarily"

Right after she closed the door, I'm inspecting myself in the mirror again. I'm feeling my body with my hands, but it's a strange, abnormal sensation. Numb, stubby, not quite how I remember it. But that was long ago. I reach for my face and try to rub my eyes. But it doesn't work. "Ding" "Clack". Why does it sound like that when I touch my face? I'm seeing me touch my face in the mirror so why does it sound like that? Quickly I get tired. Time for a nap. I'll figure it out tomorrow.

I awake back in the dark box to the voice of princess.

"Good morning dear. I have good news. Your transformation is complete! Oh I'm so jealous... A body like this, well it's a miracle. Or at least it will be after a final finishing touch. I spared you the pain from all the operations but I really want you to be awake for this last one."

I feel the box rotating to make me sit upright. The box opens into two half shells, I can finally see the outside. There is princess. She's looking at me with admiration. I observe my surroundings. Both arms and legs are gone again.

"Yesterday must have been weird.

That was just a systems test, it'll get clearer in a second. Let me first give you a tour of your new body!"

A mirror is wheeled in front of me. The creature looking at me sends me into a panic. Is that ME?? What has she done to me?? Is that even human?

"Sshh ssh ssh it's alright. I knew this would be a shock. That's why we had to do a reality replacement for the test yesterday. See, this, what you're seeing and feeling now. This is real life."

"You won't look like this for long. We're calling this form the larvae. We'll add attachments later that will turn you into the beautiful creatures you and I are dreaming of."

I'm still panicking, but princess calms me down a bit. It's what she wants. Even if I can't understand the fleshy cyborg monstrosity in front of me, it's to her design.

"So let's start with your extremities. They're gone for now- but! You'll get really cool new ones! And they'll be even better than those old meat wings you had before. Plug and play accessories! We'll attach your limbs in time don't worry. First we need to seal you in. But I'm jumping ahead, back to the tour."

Princess waves her hand above the mirror reflection like a school teacher presenting to class in front of a whiteboard

"So let's continue with your torso. Everything around this bit. It's looking pretty gross right now I won't lie. But it's all state of the art stuff! Oh I have a list of all the mods, where is it?"

She found it

"Ah there. So, upgraded respiratory system. You don't need to breathe anymore. There's still an opening for oxygen intake but it's much more efficient. It just gets cycled through tiny vents in your chest. You won't even notice. That's to free up your mouth for potentially permanent plugging."

"Next is a very similar rework of your digestive system. We were really able to compress your torso by getting rid of that! You'll still be fed some nutrients and other stuff through tubes regularly. We placed it where your belly button used to be. That's a personal touch of mine, isn't it cute? I would have liked to get rid of that system altogether but the specialists said it's not possible.... So yeah, again, all to free up your mouth"

"Artificial heart pump... and a few other things but yeah that's pretty much the gist of it. You'll be far less maintenance than you used to be. Remember the regular work that had to be done to you during vault time? None of that is necessary any more! No blood-clot prevention massages, none of that. With this core system you could stay in the vault permanently, given you're plugged in of course. But I'm not sure how much you're going to be in storage with your fun new body."

"Let's get to your head. I see you tried to touch your face yesterday and were a bit surprised by what you felt. That was the reality replacement not quite matching reality. So this is what you actually look like"

I now understand the sounds

"So yeah not a pretty sight right now but it's built to be modular and expandable!"

I agree with the first bit

"Hardly anything biological left up there. Now you won't look like this most of the time. We'll try some attachments later. But let's see what we have available without those. Two front-facing cameras act as eyes. They're very hard to see. This is all function over form so they don't look too stunning. Don't worry we have some beautiful eyes prepared for us to get lost in! Nose has been removed, quite useless that thing. Between where the eyes used to be is now a big data link plug for the attachments. This special plug reaches deep into your brain to connect the attachment systems with all the brain implants. And obviously the mouth... well it's more of a hole isn't it? Void? Without attachments it's just an empty space. There's no need for air or food to flow down into your torso which lets us compress the neck quite a bit as well. The neck is only a few centimeters thick to connect the nervous system. That uhh... neck, or wire I guess is more accurate, has also been extended. Its length can reach up to a meter. Now it's set to about human neck length. In larvae form we have to add some constraints to stop it from snapping so it appears a bit thicker now. But yeah.. mouth-wise it's pretty much nonexistent. There's just some supports to hold up the brain. Any bit of your vocal chors is also gone, but I think that's hardly a shocker. No worries though! We can still synthesize sounds for you to express yourself. Or even better, some of the attachments have organs that can create sounds naturally! I felt with all this artificiality I wanted to at least keep your voice biological when possible"

She isn't kidding. My entire head is completely unrecognisable! She's underselling this hard. I can see through my head! There's a slab of brain, then a thin wire and finally my shoulders.

My brain is encased in a translucent plexiglass shell. I can see microchips and wires attached on the inside

"Okay let's finally talk neuroaugments. You already experienced full reality replacement yesterday. When replacing eyes, a computer is needed to translate the raw camera signal into one that your brain can understand. So anything going into that can be altered and we can run live visual effects in real time as a pre-processor to alter your vision. In the future you will learn to adapt those effects as you wish so you can change what you see and how you see it. If you wish to see real life, I'll be very happy. But given how drastic these changes were, I felt it was fair to let you escape reality if it becomes too difficult."

Reality replacement? So yestersay when I was standing in that room in front of the mirror, that was all fake? I was just programmed to see that?

"Oh I almost forgot! Of course, your private parts. Well as you can see they're gone just like your mouth. Everything down there has been removed and replaced with what we call the Primary Port. The nerve lines are still intact and can be connected to your new attachments"

I must have not looked down there yet, or maybe my mind intentionally blanked it out. But she is right. My sexual organs are entirely removed. What's left is a giant hole, an absence of anything. Just like my mouth, it merely serves as an attachment point now.

"The primary and secondary port, which is your mouth, I forgot to say that, had to be eroded to the absolute limit. Through attachments we can shrink or grow them to whatever shape and size you, and I, could imagine!"

I think I understand now. This form, this abomination of what used to be human, is just the minimal body that can be expanded to take any shape we want. It's the minimum amount of body necessary for me to live. My head has already been shrunk to the size of a small pillow. My neck is essentially a thin wire. And my torso is more like the bottom end of a vacuum cleaner that you just pull around with you to house all the internals.

"Okay that should really be it. We will now seal your torso into the shell. Once that is done there will be nothing biological visible on the surface. It'll also be impossible to open back up again. I'm afraid decompression will cause instant death"

"Your head is already fully transformed. We just need to seal up the body. It will be squeezed and shrunken down to about 60% of its current circumference. The smaller footprint is going to open up so many exciting new possibilities!"

So that's what she meant by decompression. What is she planning? What will I become??

"This might hurt a little bit initially but I'm told once the seal is complete and pressurized you will not feel anything down there any more. At least nothing you don't want to feel"

I like the sound of that but the compression still sounds dangerous.

"Okay tell me when you're ready. Nod once if you understand and are ready to proceed. We can also do this without your consciousness active so if it's too much, just shake your head. The compression will happen regardless though, no way around that"

After everything she has done to-- for me. After all that I have survived. Yes I am ready to face it. I want to see this

I nod.

"I am so proud of you"

Princess hugs my torso, strokes my visibly-exposed brain and kisses me 3 times, from head to torso to... down there.

The two shell parts are brought towards my left and right. I see glimpses of their outer shell in the reflection. It's a white shiny kind of expensive looking plastic with pretty metal inclusions. The two shells form a perfect, snugly fitting cylinder-like shape around me. They snap shut mechanically, like injection molded plastic pieces that are impossible to get apart once fitted together. The fit is incredible. You cannot see any seams.

"Okay the shell is placed. Time to fuse the shell to your organs"

Immense pain fills my entire being as what feels like a thousand harpoons penetrate the core of my body. The shell is hooking into my body, connecting its systems with the exterior ports of my organs. The feeding tube and ventilation system finish with a satisfying click and hiss as the seal is made. The bottom of the shell molds around snugly just above my "Primary Port", leaving no visible panel gap between the shell and the port's metal rim.

"Good all connected. It's time to compress. Three, two, one..."

The pain is indescribable. The relentless torment shudders throughout all over and deep inside my body. My mind tries to scream but it's a hopeless effort. I have no organs left to voice my suffering. No arms to wave for help. No legs to at least struggle. Nothing is left. The shell, this corset from hell, is physically crushing me into the size of a handbag. And just as quickly as the pain came, it fades.

"That's it. You are complete"

I look in the mirror. This creation in front of me. It resembles a human no longer. It's a robot, a DIY creation platform for synthetic animals. The bare essentials. A vessel for human meat to be kept perfectly alive in an unimaginable biological state of being more machine than man. What's left of me, my original me, is a mere brain, nervous system and some bits of inner organs that could not be replaced despite everything else.

But now that the transformation is complete, and I see princesses' wide grin, one so wide and cheerful that I have never seen before, what I see isn't an abomination, it's the beginning of my new life. My new life as being anything princess can imagine. And as has just been confirmed once more, her imagination knows no bounds.

"Congratulations dear. Oh I'm so jealous! You're the world's first ever trans-species polyhuman! You, my love, are no longer human, not even transhuman. You are everything."

I've been shrunk to the size of a handbag, or perhaps a large basketball. There's mechanical ports available to attach any peripherals imaginable. There's ports for attaching arms and legs, a socket for the belly-button feeding tube, tiny vents for breathing with attachment points for rerouting. Empty gaps at my primary and secondary ports for endless fun. I have carry handles positioned at convenient spots which are sunken down into my core.

Did she say polyhuman? Yeah that describes it well.

"Okay let's not beat around the bush, I want to attach something!"

Princess grabs me by a handle that is apparently placed on my back, carrying me around effortlessly like a handbag

"Oh wow, not as heavy as I thought! Haha wow I can really just pick you up and carry you around like this!"

It feels like I'm flying. Suspended from above with nothing below me. It's a surreal feeling. She puts me down on a desk, facing a wall full of attachments.

The selection is immense. Cat-heads, dog tails, horse legs... The whole lot of animal parts are present in all kinds of styles. Some bits embrace the synthetic nature while others look eerily realistic as if it was taxidermy. Human bits are represented as well. Full bodies into which a polyhuman like I could be inserted. But as an ominously labelled box "Experimental" reveals, that's not the end of the selection.

"I should probably give you a human body first but I'm getting impatient! Let's do my favourite right away! I just hope you'll get to enjoy the others in time because I've been looking forward to this since I met you."

Princess brings the box and begins attaching all the bits to me. She starts with the torso skin. It's a soft and shiny latex-like material that fits to my shell. The white color's shade is as pure as clouds. On the outside the material is a fascinating fluffy substance. Not quite hair, but almost like a plushy. It's an indescribable material but by all means a beautiful skin, both artificial and natural looking and feeling.

Next is the primary port. It features a large fleshy, round hole. The material looks like fleshy silicone. Once it's attached I am able to start moving around some bits down there, clearly built to stimulate men of impressive caliber. An alternative attachment in the box features an extremity built for the joy of the opposite sex. Presumably its size can be adjusted by me in real time when worn.

The legs are next. All four of my ports are used as legs in this configuration, forcing me into walking on all fours. Stunning pieces. They're elegant horse-legs with a sexy girly touch. Curvy and graceful with female design, ending in golden stumps, about 3 centimeters tall. After the fourth one is attached, I stand up and feel the hooves. The feet end in a small stiletto-like stump and I'm able to curve the ankles forward to stand quite securely on sharp pointed tips. This is my favourite so far.

"Oh you're looking so cute already! Just the head!"

She pulls out the head and attaches it to my primary port and over my brain. The connections click shut and I can finally see out of the head's own cameras.

"And done! Oh I could kiss you already a thousand times but you should get a look first! Here, walk to the mirror!"

I take steps towards the mirror on my right. The pointed tips of my new golden hooves clack against the floor tiles in a way that's at once regal and graceful but also slightly menacing.

I see myself in the mirror finally. I'm a unicorn. A real unicorn. Fluffy, girly, beautiful. My white skin is fading pink patterns in satisfying and slow motions, like a pretty screen saver. I think I might be able to change the color of my skin. I concentrate and manage to fade my head into a light magenta.

"Oh look at that you already figured out the full color skin!"

I shift back to white but keep slightly flush cheeks. It feels right. My eyes are beautiful shining pearls. Not quite human but also more detailed than real horse eyes. A large black pupil is surrounded by a tasteful small golden and pink ring. I have pink eyes!

I have a horn too! Its size is perfect. Not too long, not too short. Slightly nubby and cute but also still a proud horn. I open my mouth and discover an endless void, looking very similar to what my primary port feels like. It's slightly startling and unnatural but in the mirror I see my tail wagging. I have a tail!! It's just as cute and perfectly pink and golden-accented as the rest.

Princess has immense taste. No this is my taste. I dreamt of this! I remember now! The dream-surveys. All those nights! This is what I dreamt of! I dreamt of being a beautiful fluffy unicorn! A little puppy! A cute cat! I always dreamt of being someone's real, loved little pet. Not a human pretending to be a pet. A real one!

"Oh come here you! Look at you! We did it! You did it! You're my perfect little unicorn! Exactly how I dreamt it! I just had to make you want it too!"

Princess is cuddling me intensely. I can no longer feel the pain of the compression from earlier. All I feel now is princesses' sweet love.

Did she say she made me want to be like this? Did she brainwash me to dream of becoming a cybernetic abomination so she can have a pony?

...

I scream

THANK YOU PRINCESS!

But out only comes horse-voice

I LOVE YOU PRINCESS!

"Awww no thank you! I can understand you don't worry. Only I can."

THANK YOU FOR TURNING ME INTO A PERFECT UNICORN! THANK YOU FOR MAKING ME POLYHUMAN!

Princess hugs my neck and whispers

"Shhh.. little one. Princess you say? But that's not me my dear. It's you!"

Princess picks up one last thing from the box.

"You're my precious little princess. You are... you're everything I want to be."

Prin- no. I- I am...

I'm the princess? A unicorn princess?

My prin- no, my guide places a golden delicate tiara onto my head. It attaches to ports on the top of my skull and snaps firmly in place. Its design is immaculate. Solid and proud but still fine-grained and detailed. It sits proudly atop my head, completing me.

"I always wanted to be a princess growing up. And this. This is all I ever dreamt of."

The wonder inside me at the sight of this tiara completes my life. At once, I remember all the procedures. I remember all the time I spent in the vault. Everything, all the years of my life I devoted to her. All the mind-altering. It was all for this.

I am filled with endless bliss, joy, love, gratefulness and lust. In tears I lie in her lap and let her stroke my mayne and permanently attached tiara.

"We will try out other forms in time, but let's take some time to enjoy this one"

She draws closer, whispering into my ears

"And a little secret: Now that your procedure was a resounding success, tomorrow I am going to go under the knife as well. I will become a beautiful princess just like you"
