Chapter 5: 0x04: Lilith II

No, you take it back. This is the stupidest thing you’ve ever done.

Thank fuck your parents are having dinner out tonight. This is something you really don’t want to be caught out on.

Your materials finally arrived from Sunset after that background check cleared, so you spent the past couple of days – with, admittedly, very little sleep with how obsessed you’re getting over this project – and you completed your second tail prototype. ’bout fucking time, too, you’ve just not been able to concentrate on anything else, thinking about how amazing this tail was going to be.

The materials used were developed for soft robotics applications; you envisioned it so clearly, a razor-like tail that can glide smooth over skin then slice through unsuspecting would-be gropers in a mere moment’s notice, yes, that’s wonderful…

but it’s the tip that’s really amazing.

It would take several hours to explain how it works, and that’s discounting the lecture on what the word ‘cybernetics’ actually means that you have to repeat to Inle every time, but suffice it to say it’s amorphous. It can change shape, change tactile and haptic properties, generally just transform into whatever you need it to. It’s not as capable as Iri’s tail in Windam’s story, sure, but that would require magic and miracles, pretty much – Iri can hide hers, for one.

(Which seems a shame, really. Who would want to hide it?)

…and the black, shiny, latex-esque coating? Well, that’s just personal preference. Alongside the lines of violet light that show off the tail’s technological origin. A machine succubus.

(Look at you, hacker.)

You’re not going to be convincing anyone to wear this thing anytime soon, but it’s just…it’d be such a shame to not have someone try it out, right?

So. Like you said. You’re doing something stupid, which is why you’re in the bathroom, the walls currently in mirror mode to provide a viewpoint of your naked, pale body that apparently people are trying to make fun of for being effeminate or something.

Because lacking any test subject, you’re testing your new, wonderful succubus tail prosthetic…

on you.

It’s fine. It’s the late Reiwa era, you wouldn’t even remotely be the first. And it’s not like you have to tell anyone. It’s a bit embarrassing, you’re not a girl after all, but who would you ask? None of the girls in your life are anywhere close to this – although maybe Priscilla would do it, but somehow that almost makes it worse, like she wouldn’t have self-respect to stop you – and it’s not like something like this belongs on a guy. Maybe if you test it out, you could see about distributing the plans or something.

(Even if you know in your heart this belongs to you and you alone.)

Sure, you went to all this effort to shave beforehand, but is this really going to work right? This look? You guess if you’re all hairless like this, bending down so you look slender, and have a vaguely effeminate hairstyle, you’re an appropriate model, but…

Do your hips really look like that? At some angles, you really do look like a girl. You have to look pretty hard, squint a lot, but you think it just might work well enough to give you an idea of what it’d look like on someone else.

It’s not like this is the finalized model. The tail will come off, albeit with difficulty. You don’t have to keep wearing it. Even if it might be pleasurable…

Even if.

Sure, it interfaces with your nervous system, but it’s not invasive. It’s just an extra limb of a sort, nothing special. It’s not too different from prosthetics that already exist, probably. Not like it’d feel wonderful to wear it, like it’d be fulfilling. Not like you have hazy memories every morning about it…

It’s time to stop stalling.

You carefully sit down in your retrofitted shower chair, made to hold the tail in the right place as you descend. With the precision of a perfect machine made by your own hands, you…

Ah –

It feels good…

As it hooks itself into your flesh and against your nerves, digging into your flesh and seeking out subtle movements and nerve transmissions, it doesn’t hurt the same way you thought it would. It’s so easy, so simple. It feels like coming home, it’s a good pain, the kind of pain you never imagined was real.

In fact, it’s so indescribably wonderful, the pain is so good, you think you might have had an orgasm. Or it felt like that, with the pain…

Are you a masochist? No…

No. With this sharp tail, so mobile, so mesmerizing, you surely must be a sadist. Your brain melts into the newfound sensation of bearing a succubus tail, as it expands its consciousness to an entirely new part of your body. It moves like a limb, gliding to and fro, under your complete control. It can even brush against your cock, around it, in perfect comfort, and even against your…

y-your ass?!

Nngh. You’ve got such a dirty mind. It’s like when you wore it, your desires surfaced, your desires opened, and you wanted to feel that tail. Just because…nnf. Just because you’re a little curious, or you’ve done it before, with your ass…it’s nothing strange. Wanting to be filled as much as fill…

Oh, you aren’t gauche. You aren’t some sex-crazed beast. A demon that can only think of sex is unworthy of the throne. But you do think of it, and you do want both. As it strokes and fills you simultaneously with something that could easily harm another if you ever so willed it. You want to use this new tail on yourself and on others, in equal measure.

And why not both?

Why not push inside, inside yourself, and moan with your hands perched on your cheeks, imagining your possessive face looming over a girl…

Girls should be…mnf…full ????

It’s not just a sex toy, mind you.

Once you get into your room, you’re surprised by how easily you can use it as a limb. It’s like it’s already an extension of your body, your brain. With how mobile it is, it can lift and move things, hold tools, even use a touchscreen. It’s like having a third arm or hand. Even complex and delicate tasks are no barrier, assuming they don’t need fingers or opposable thumbs to accomplish.

It’s like it’s always belonged there.

It’s like you were meant to have a succubus tail.

Of course, you can take it off. Any time you like. Any time you want or need to. You couldn’t possibly get caught with it at school, after all – Pedersen’s uniform code might be pretty lax, but this would definitely be too far. And where’d you even hide it?

Inside you…oh, that is tempting. That’s tempting, but you mustn’t. If you’re caught like that, you’ll never hear the end of it. And it would never be that comfortable, anyway. There are limits to the human body. Such awful limits. Ruining your fun already.

(Look at you, hacker.)

Even as your tail is hard at work with the rest of you on new designs, new thoughts, new concepts blooming from your brain and flowing from the base of your tail, you’re not idle. Oh no. You’re…nnh…you’re enjoying it. You’re enjoying, a thick plug spreading out your ass, pushed in, your cock leaking from the pressure on your prostate, the toy attached firmly to your chair so you can train yourself to stretch more. Take more. It’s an absolutely fantastic feeling, and you don’t even understand why you were so scared or hesitant to pursue it in the past. To pursue such…lovely pleasures as this ????

(Girls should be full, after all.)

You’re missing something. You’re missing something so important. More important even than a tail. And yet it stretches into places you’re clearly not qualified to go…

but you’ve already come this far. You can’t possibly stop now. You can feel it, within your tail, that this is only the start.

Just a little more, and the world will open up to you…

That night, you dream of the throne.

Stand before the Echidna’s throne. Become the Demon Lord.

The tail is part of your ascension. A bridge between what you are and what you wish to be. By your own hand, you will awaken. By your own tail, Earth itself will fall to you.

And only beautiful things should exist.
