Um…um, oh dear. Oh dear oh dear oh dear. There’s a tentacle growing out of me! That’s not normal! I’m not even transformed! It’s just all wiggly and slippery and coated in ink! And it’s filling me…

I reach between my legs and run my fingers along it. I can feel it wanting to come out. I can feel it trying to escape. My panties are being totally stained by them…shiny black stains of dark fluid, how will I wash that out? I’ve got my sheets, too! Oh dear, oh dear oh dear oh dear…

I don’t know what to do! I want to birth a tentacle! I want to ink! I want to masturbate! I want to see what happens, but I don’t think it’s a good idea, and –

“Hey, Shiorin! Are you enjoying your new toy?”

N-not the best wording, nee-chan! I haven’t even touched my Iron Valiant yet! I don’t wanna cover my new model in ink! I-if I showed my tentacle to my sister, even she would think I was the Astral Queen Maledicta that the news is saying so many horrible things about! What do I do?!

“Everything okay in there, sis? Heh, or do you need your big sister’s help with your homework or something?”

S-s-shiori Panic!

I have to get away! I can’t be caught with this! My sister will know I’m the prophesised leaderess of the forces of evil and that would just be absolutely awful! I’ll have to go take up the bathroom or something! I’ll just have to run! I hop off the bed and rush to the door and –

oh

As my sister slides the door open, I don’t have time to move out of the way! I crash right into her chest! And it’s crazy soft but I can’t think about that right now, I have to –

“Shiorin? What’s that against my leg?”

H-huh?

Oh no.

Oh no oh no oh no oh no oh no! Hikari has noticed my tentacle! She’s seen it! She’s seen how it’s dripping with ink! She can feel it writhing around her and trying to reach for warmth right now! There’s no way I can hide this! I’m going to be locked up in some kind of asylum for supervillains! I’m going to be put on ice! I’m going to be dissected and minced and made into takoyaki!

Hikari pushes me away, and slides the door back closed, and she’s got this huge grin on her face, and –

“Oh, my little sister is growing up, huh?”

Wait, what?

“What is that thing you have there? Go on, show me!”

“W-what? I don’t have anything!” My sister looks…um, not mad? She looks like she does when she’s pulling a prank or something! “I don’t –”

and then it falls out.

An ink-coated tentacle, writhing on the floor, which my sister picks up with her hand, looking at it like it’s…well, not ordinary exactly, but like it’s not an abyssal tentacle from the deepest depths of the ocean!

“Where’d you get one of these? Wait, no, don’t tell me. If you told me I’d have to tell mom and dad.”

Um.

“Jeez. I know Zumi-chan told me these were really realistic, but this is something else.”

Uh.

“It’s all writhing and warm and shit! Seriously! Heh, she was super drunk when she was telling me about all the weird soft robotics sex toys they have over in Southern Sun, and she was surprised I didn’t have one of my own. Like, really, do they think everyone in Japan constantly thinks about tentacle porn or something? I guess someone must be if you could get your hands on this, though. Whoever gave this to you is a real degenerate.”

Um.

“Ah, how nostalgic~ Don’t worry, sis, this’ll be our little secret. But I need to borrow this so I can rub it in Zumi-chan’s face.”

What?

“…sure?”

I say it before I even realize it, and for a moment I think this is when it’s all going to break! This isn’t good, right? I can’t let my sister have a hold of this thing! It’s proof I’m the Astral Queen Maledicta! Even if she doesn’t know right away, she’ll definitely find out later, right?

“Great!” Hikari says, winking at me. “Eheh. I’ll make it up to you. Just lemme know what you want and I’ll buy it for you. Just don’t tell mom, yeah?”

I can’t just let her walk out with it in her hand, writhing inside it, and let her go off to the guest room to do who knows what with it! Like she did just now!

…

…

…ah, it’s no good, I can feel more of them growing inside me 🖤 I can feel my soul burning and I pull down my panties, pull off all my clothes, just so they won’t rip as more tentacles emerge from me! I hop right back into my bed and spread my legs open so I can feel them birthing from me! Aah, isn’t this supposed to hurt?! It’s supposed to hurt when something pushes from your womb, is birthed from you, but all I can feel is the lovely, perfect sensation of the bulge in my belly and the tendrils wrapping around my legs, my arms, pulling away my bra so I can pinch and tug at my nipples, mmf 🖤

My sister, my precious older sister, took one of my tentacles and is none the wiser! If she gets much more drunk, there’s no way she won’t put it inside her! I get to fill her with my tentacle by proxy! It’s absolutely delicious to imagine, and I know I should stop, but I can’t resist! I want to ink!

I can feel my tentacles sucking on my nipples, and I have to bite down to keep from moaning! Another tentacle is pushing against m-my ass, and my ink is coating my anus, it’s pushing through! It’s so delicious! I can even kiss my tentacle and swallow its ink 🖤

Oh dear, I’m not supposed to be evil, but it feels too good to stop! I can feel my consciousness expanding through space! A cosmic glow! M-my pleasure, my ideal future, lies over the rainbow! L-love is the pulse of the stars! I’m going to ink 🖤

Spraying between my legs, my tentacles go haywire and ink me all over 🖤 I’m going to be utterly coated in it! Yes, please coat me, please tighten over me, please kiss me, my beloved tentacles, my magic, my power!

I can’t resist. I can’t resist inking, I can’t resist coming. My sister, my precious sister, is going to become just as addicted to tentacles as I am! And soon, soon, I’m sure I’ll get to ink inside her, too, and she’ll learn the joy of the deep just as I do…!

I’m coming…!

…

…

…oh, that felt so good. Oh, I’m so sorry, everyone, but I hope even if I don’t become a leaderess of evil, I can still show everyone the pleasure I can bring them –

Oh, um. Oh dear I’m going to need to change these sheets, aren’t I. They’re absolutely soaked. Coated in shiny black! My panties and bra, too! I don’t know how you get dark fluid out of things! A-and I’m definitely going to need to take a bath, too…

A-at least I can conspire with Hikari, but maybe she’ll be upset if she gets ink places she shouldn’t?

Oh well.

Shiori’s parasites can now be attached to other girls as well as herself. Getting parasites attached has an addictive effect, though the parasites read as kajiu-like.

I’m sure it’ll be fine.
