#k.tentacles

!!! thank you for indulging my idea <3 see my earlier ramble on tentacle monster kylar here ! they’re most like an octopus/human hybrid, tho not exactly like it, and some headcanons are based on that!

There’s some differences in what they’re like, depending on their gender. As a girl, she’s larger and stronger than her male counterpart. She’s more dominant during sex, almost becoming rough, since she doesn’t realise just how fragile you are. Sucker marks will be littered all over your skin by the time she’s done with you. Outside of that, she’s also touchier. She doesn’t hesitate to pull you close and try to let you stay a little longer than you want to. However, if you turn the tables on her, she gets so embarrassed she can’t function for a little while. Females of their species are known to try and cannibalise their partners if they’re hungry, but Kylar would never, ever even think of doing such a thing to you!

On the other hand, if male, Kylar is a lot more hesitant. It’s an instinctual thing, the fear that you might become aggressive keeping him from doing everything he wants to. He is constantly looking for your approval, and more likely to show off. Even if he is large compared to you, he still sees you as his mate, and he’ll remain nervous. His tentacles will carefully wrap around your waist and tug you closer, delighted when you don’t hurt him. (Even if you struggle, your teeth and nails aren’t sharp enough to cause pain, let alone cut him.) Around him, it’s common to see some ink leave his mouth and dissolve into the water. A nervous habit. It’ll take longer for him to fuck you, unless you help him, but once he does, he’ll keep at it longer.

Either way, they really, really like you! You’re warm and cute and nice and you keep visiting them! To hold you as long as possible, they’ll move up to the surface and float there. They’ll either let you lay on their chest or prevent you from sinking with one of their tentacles. Their eyes are very sensitive to light, so they have to keep them closed and can’t see your face, but they consider this a worthy sacrifice. Kylar’s skittish, though. They’ve got scars on the ends of their tentacles from when a group of humans caught when they were younger. It’s the reason that, despite their loneliness, they stopped going to the surface. You make them feel safe enough to do so again. Even then- As soon as they hear multiple voices near the water’s edge, they’ll dive back under, taking you with them.

They’re not familiar with human ways of affection, but if you introduce them, they’re never going to forget. Hold their hand? They’ll intertwine their fingers with yours, or curl the tips of their tentacles around them. Kisses? Oh, they love them. Your lips are so soft! They’re always sloppy though, dragging the tip of their tongue over your skin at the end of every kiss. You taste good, they can’t help it. Kylar changes colours when they’re embarrassed, tentacles turning from a deep purple to a pale pink, and your presence never fails to lighten their hue.

The slime on their tentacles have effects days after they touched you. At random intervals, the skin will tingle and turn warm. Once they’ve been inside you however, it gets many times worse. Heat settles underneath your skin and refuses to fade, your thoughts circling back to them and only them, leaving you unable to function. Not your own fingers, nor anything of someone else, is enough to sate the need. You go crawling back to the water every time. And Kylar is more than happy to oblige, stuffing you full as many times as you want them to, to make you forget about everyone except them. They’ve been so pent up for so long that they’ll push you to your limits if you let them. Each time you give in, it gets worse, until you have to stop by daily. Your body starts to change, letting you stay underwater for far longer than should be possible. Their language, clicks and gurgles, whines and mewling, starts to make sense to you.

cw: tentacle monster kylar, weird numbing slime stuff,

You swim through the ruins at the bottom of the lake, searching for treasures to sell. With your increasing debt, you need to keep getting more creative in your ways to make money. Digging through the pot, you halt as you lean over. Something is curled around the bottom of about as thick as your forearm. Hesitating only a moment, you prod it. It's slimy and cold and it twitches at your touch. You suppress a shudder. Your finger tingles. What the hell is that thing?

A noise, distorted underwater, sounds from above. You don't want to look. Maybe if you don't, you can pretend nothing's there. But... Things can never be that easy, can they? As your gaze travels upward, you take note of the slimy thing climbing up the wall. There's more of them, crawling all over the place like otherworldly vines. All leading to the same place. It's too dark to make out where. Then the darkness moves, limbs writhing on rock as it leans forward until its face is close to yours. Emerald eyes pin you into place. Its a humanoid something, the upper half of its body looking like a girl your age, one that looks as surprised as you. She's perched near the top of the wall, practically dangling from the ceiling. The tip of her tentacle sneaks around your ankle. You yell without thinking, and a large bubble of water escapes through your mouth. The monster flinches back, its hold loosening.

cw: body horror (kinda?? mentions transforming to be more monster-like.)

They absolutely get jealous. If there are any marks left on your body, like bruises or hickeys, they’ll want to leave twice, no, thrice as many of their own. Or leave blotches of ink on your skin that are near impossible to remove. Afterwards, they’ll press kisses to the marks while whining out apologies. ...But they can’t have people be confused about whose mate you are! Finding someone else’s cum inside you will distress them. If they were around you all the time, they would fight competitors to keep you as their mate. That’s impossible for them though, they can’t protect you all the time. They won’t get mad at you, they won’t hurt you, but they are scraping out every bit of seed out with their tentacles, which is uncomfortable at best.

Their jealousy is the worst during winter. Obviously, because of the low temperatures, you can’t go in the water with them like normal. There won’t be any iceskating that year. Kylar keeps breaking all the ice in frustration, occasionally cutting themselves on the sharp edges. Members of the Temple will whisper to each other about a wailing coming from the direction of the forest at night. Suffice it to say, they miss you. This is the case even if you continue to visit them. Having you sit on the beach, as close to the water as possible, and chatting to them while stroking one of their tentacles alleviates the worst of it, but not all. They’d never force you into the water, however. Maybe it’s still smart to invest in a really good wetsuit. 

bff’s people have an intricate mating ritual that’s long, exhausting and possibly damaging for both parties involved. there are so many limbs to keep track of. while it will never fade out of their society completely, it cannot be denied they have been looking for more… convenient options for ridding themselves of (unnecessary) eggs. but it’s still an intimate, bordering on sacred, act.

so when she takes you back, the perfect little breeding creature, you are treated with the utmost care. worshipped, almost. given the finest food, clothing and housing. all to ensure you’ll take their eggs well. you won’t have to do anything on your own! if they let you walk on your own, you’re lucky. they’ll feed you, bathe you, dress you, carry you, entertain you- eager to listen to your every command. you’re so, so precious.

they don’t immediately breed you. no, no, of course not! bff is all over the place, getting everything together. getting them to take forms that are less terrifying. teaching you and the others some basic worss in each other’s languages. placing triggers in your mind that will have you forcibly relax upon hearing them. the usual!

they’ll get to it eventually, though. (and bff always gets to watch. if one of them doesn’t treat you gently / isn’t pleasuring you enough, she’ll send them out for you. …unless you communicate a different preference, of course.) you’ll be stuffed full by creature after creature until you’re swollen and a sobbing mess, leaking cum. no matter how much they coo at you, the stretch is unnatural. and they make you cum so hard it almost hurts. but, most of the time, all you can do is relax and let them take care of you.

anon thank you for sending me one of the best asks ever. terrifying crossover. male kylar for clarity's sake,, using those makes it clear who is being referred to the whole time <3

cw: tentacles, implied mind control (slightly, on BFF's part), overstimulation

Good luck! Just. Good luck!!

You're going to have to fuck in some body of water, because Cyan and Kylar can't last long outside one. There's... Going to be a lot of bickering going on. Kylar is horrified at the fact that some of Cyan's tendrils can harm you, and it's enough for him to want to keep the jellyfish out of it entirely. Especially with how nonchalant they seem to be about it. (They just don't understand pain!)

Honestly, he doesn't want to share at all. Unsurprisingly. They listen to Kylar and only intend to use specific ones after, but BFF uses her hypnotic powers to confuse them. Makes them think they're reaching out with the right one, when they aren't.

BFF sets these two up to clash, and ends up having the most fun there. While they're busy arguing (more like Kylar freaking out and Cyan trying to tell them they'll watch out, really, they will!), she's actually getting her tentacles wet already. Clicking her tongue and shaking her head before giggling. They really are neglecting you... Poor thing. You're lucky she's here! Before wrapping a tentacle around your legs and starting to touch you. Kylar is the first one to notice. He temporarily forgets about Cyan, latching on to you even more, insistent on making you feel better. BFF keeps 'coaxing' you into singing her praises, while he snaps at her to quit controlling you. She just sticks her tongue out at him.

Then it's Cyan's time to shine. They've got the thinnest tentacles out of any of them, and since they're using the right ones, they can just slip right underneath the others and touch you too. Firstly, they curl two around your nipples to twist and turn. It's an obvious first pick to them! They lack the things you have on your chest, so they're just curious how they feel. It grabs the attention of the other two once you start to squirm.

Kylar is completely done at this point. He has to touch you. Has to prove you how he loves you more than those other two. He's drawing hearts on your skin using his ink with one tentacle, and already spreading you open with the other. It's too quick of a stretch, which has him immediately flinching and feeling terrible. BFF whines out a no fair, and that he should feel bad, you're not even feeling good right now! Kylar has no choice but to sit by and watch as she cooes at you to make your muscles fully relax. The pain ebbs away. She lets him kiss you and apologise and sob while fucking you, but not without slithering one of her own tentacles inside you. (Don't let her bring up the subject of eggs. Kylar's already on edge enough.)

Cyan is likely the one getting the most stimulation next to you, having slithered many of their tentacles around Kylar's and BFF's. They're getting squished in between the two, rubbed everywhere. It leaves them too out of it to do much claiming, just floating with a dazed smile on their face. (Until they accidentally put in one 'bad' tentacle, and it has all of you crying out.)

Oh la la~

gonna give this idea a bit of a spin <3 cw: hypnosis/maybe more light mind control?, dubcon, tentacles, overstimulation

She's discovered porn since coming to Earth and while none of it's applicable to her, it is interesting! (And definitely gives her some skewed ideas on what normal sex looks like.) What exactly is appealing about glory holes to her? Well, the idea of her taking you without you even knowing is so lewd...! She can have some fun, and you won't find out about her true nature, so she can observe you some more! BFF places the desire in your mind. Day by day, the desire to visit one grows stronger, until it's irresistible. There's no way she'll let anyone else but her fuck you, though.

Imagine what a shock it'd be when, instead of a cock or literally any other human appendage, a bunch of thin tendrils sliter through. Enveloping your clit, massaging every little bit of it at once. BFF has no clue just how sensitive it is. But, luckily for you, the ones curled around your legs pack enough strength to carry you as your knees buckle. If you weren't busy losing your mind, you could easily hear her giggling behind the wall. All your noises are soooo adorable~! Your pussy is already drooling so much, and she just has to feel it...! Her penetration doesn't involve thrusts. (None of the ones she can do that with fit through such a small hole :(! ) Instead, it's a tendril that branches out into an incredible amount of tiny feelers that touch every inch of your walls.
