KINKTOBER DAY 17 - TENTACLE SEX (Omeluum/Reader)
Summary: Omeluum comes to you with a peculiar request. You decide to humor it.

“You want to do what exactly?”
It had been almost two years since you joined the Society of Brilliance. In the years since you joined, you had become close friends with a mindflayer by the name of Omeluum. Just the very idea of befriending an illithid was something you had previously thought to be impossible. And now what it was proposing seemed more impossible.
“I’m asking you if you would like to help me research the sexual functions of illithids. I understand if you are hesitant or even disgusted by the matter, but I can think of no one else who would aid me in testing my theory,” Omeluum states.
“No disgust, just confusion. Do illithids even have any sexual function? You reproduce asexually. You have no sexual organs,” you ramble.
“That is our current understanding, yes. My kin will always multiply using tadpoles. But my theory is that we can still have…sexual gratification. Even if we do not often crave it,” it says.
You sense a little bit of nervousness behind the Mind Flayer’s tone. It seems stiffer than usual as it sits across from you. Your fingers lightly drum on the wooden table separating the two of you as you think.
“So, let me make sure I have this straight. Your theory is that mind flayers can experience sexual pleasure. And to test this theory you’re asking me to have sex with you,” you say.
“Yes,” it nods.
“Out of curiosity, have you proposed this theory to anyone else?” you question.
“I have. Blurg knows of my theory. To be honest, I asked him first. But he is…shy. I do not wish to bother him with the topic,” it says.
“I see, I see.” You tap on the table again, lost in thought. It was an interesting theory, that was for certain. Every day Omeluum proves all of your preconceived notions of mind flayers wrong. It was an outsider amongst the illithids. Although it would come off as cold and analytical sometimes, the illithid would be caring and even empathetic at other times which was something many people would have told you was an impossibility.
But it was possible. So maybe Omeluum’s theory was also possible.
“Okay. I’m not opposed to the idea. Yes, I’ll do it,” you say after a moment.
The illithid’s eyes widen a bit at your response as if it didn’t expect you to agree.
“Good. I am…glad. I think it is best that we wait for the others to retire to their rooms for the night. I will come to your chambers later,” it says.
“Sounds like a plan.”
After a few hours, the Lodge grows quiet. The last of your colleagues turns into their rooms and you do as well.
A wave of nervousness washes over you as you sit on your bed, reading a book. You can hardly focus on the words on the page. Your eyes see the words but your brain doesn’t retain any of them, too busy thinking about Omeluum and its theory.
When it finally comes into your room, you set your book down on your nightstand. Omeluum shuts the door behind it and hovers over the ground to the edge of your bed, looking down at you.
“If you are having second thoughts, I understand. Please know that we can stop at any time for any reason,” it says.
“Thank you, Omeluum. But truth be told, I’m kind of…excited. At least I think I am. I can feel my heart pounding in my chest,” you say, feeling your chest. The muscle thumps and you can feel it against your hand, rapidly beating. It only increases when Omeluum sits beside you.
“I think your excitement will only help this…experiment. Even if my theory is false, it will please me to know that you at least enjoy yourself,” it says.
“Well, I hope your theory is correct. You deserve pleasure, Omeluum,” you say.
You lean closer to it, hand lifting towards the Mind Flayer’s robes.
“May I remove these?” you ask.
“Allow me.”
It moves to remove its robes and in turn, you remove your own, undressing at the same pace as Omeluum until both of you sit bare before the other.
As expected, Omeluum has no genitalia. Between its legs is a mound of flesh, no slit or appendage. Its body is the same light purple tone all over, with thick ridges running down the length of its body.
You reach towards it slowly, fingers grazing against the ridges. Omeluum’s skin is cold, unlike your own. It feels soft, slick, and almost wet. You place your entire palm against its chest, getting used to the sensation.
“You’re so cold. I think this is my first time actually touching you. I don’t think I’ve even shaken your hand before,” you mumble softly as you move your hand down its chest.
“I do realize this is a jump. But it is a welcome one. The things we do to better our understanding of the world around us…” Omeluum trails off as curiosity takes hold of it, touching you as well. Its long fingers touch your face, caressing your cheek.
“Interesting,” it says as its hand moves down, cupping your breast in its hand.
“Find something you like?” you joke.
“Maybe,” it mumbles.
It squeezes the supple flesh experimentally, humming to itself. Sighing at the contact, you move your hand from its chest, an idea popping into your head. You reach towards its tentacles, taking one into your hand.
They’re slightly slimy but not unpleasant to the touch. They curl and move on their own, reaching for your body.
Your hand slides up, stroking it softly before leading it towards your mouth, placing a kiss on the soft tissue. A small sound comes from Omeluum, almost reminiscent of a sigh.
“Did you…like that?” you ask.
It blinks slowly as the tentacle in your hand curls around your wrist.
“I’m not sure. Please…continue,” it urges.
You smile and bring the tentacle back up to your mouth. You kiss it again as Omeluum kneads at your breast, almost methodically. The Mind Flayer hums and you’re not sure if it’s out of fascination, pleasure, or both. To test your own theory, you bring the tip of its tentacle into your mouth and suck. Omeluum makes the sound again and you smile around the tentacle before letting it pop out of your mouth.
“I think your tentacles might be the answer to your theory. Have you ever touched them on your own? To masturbate, I mean,” you ask.
“No, but now I can’t help but wonder how sensitive they are. I do feel something, but I want to test further,” Omeluum says.
“Of course. Do you want me to do anything specific?” you ask.
It pulls its hand away from your breast and moves across the bed, sitting on its knees in front of you.
“I would like to do something. May you lie down?” it asks.
You nod, lying back against the bed, propping your head up on a pillow. Omeluum’s hands move, resting on your knees and spreading your legs apart, revealing your cunt to him.
It leans down and its voice wraps around your brain, as it always does, but this time its tone is different than usual. It sounds softer as it speaks. Still clinical in nature but softer nonetheless.
“The warmth of your mouth stirred something inside of me. It makes me wonder if other areas of your body would garner the same response or maybe even a stronger response. One that I can determine as pleasurable. I don’t have a tongue or a cock but I presume that these might suffice,” it says, tentacles moving as it stares at your body.
The prospect of having Omeluum inside of you makes a warm feeling pool in the lower part of your belly. The feeling is familiar, although it is the first time an illithid has made you feel any amount of arousal.
One of its tentacles slides up and down your cunt, getting the flesh wet from your folds before slipping into your hole. You moan and to your surprise so does Omeluum. The tentacle wiggles inside of you as Omeluum collects itself, taken aback by its own response.
“Omeluum, are you okay?” you ask.
“Yes, I—umm—I’m okay. It’s just….you’re so warm. So wet. I didn’t think my tentacles could feel at such an intense level,” it says, a hint of shock in its voice.
“Does this mean your theory is right? Does it feel good?”
“I believe so. And to be honest, I don’t think I want to stop even though we have an answer,” it says.
“I don’t want you to stop either,” you say.
Omeluum nods its head. Its face is always hard to read but there is something behind its eyes that’s different than usual. You didn’t know how likely it was for an illithid to experience lust but in that moment you could have sworn that’s what it was.
Its tentacle moves inside of you, sliding in and out at a slow rhythm. It buries deep, curling inside all the way up to the entrance of your womb.
It feels different than an average human cock. It flexes and flows in you like it has a mind of its own, dragging against your inner walls and swirling around until it is as wet as your cunt.
Omeluum’s other tentacles move up your body. Two wrap around either of your breasts, squeezing and massaging them with the slippery appendages. The fourth and final one slips into your mouth. You accept it graciously, allowing your tongue to swirl around it before sucking it.
Omeluum, being an illithid, can still speak freely as it occupies inside of you with its tentacles.
“This is…good. You feel good. The way you’re wrapped around them, the way you tighten against them. This is better than I could’ve imagined,” it moans, voice dancing in your mind.
You can’t speak but you moan in response around its tentacles which seem to make it feel even better, a whimper coming from it as it feels the vibrations from your mouth.
Omeluum thrusts into you faster, and as your own pleasure builds you can’t help but wonder how it feels for the Mind Flayer. It's clearly enjoying itself to some degree. But what did it feel like exactly? Knowing Omeluum, you were sure you’d get in-depth research notes shortly after the encounter. Your own questions would be answered soon enough.
You can feel yourself contracting around the illithid, your pussy clenching with every thrust as it fucks you with its tentacles. Not only can you feel how soaked you are but you can hear it as well, wet squelches echoing throughout the room as Omeluum’s tentacles work inside you.
At the pace it's going, it doesn’t take long for your climax to hit you. Your cunt tightens around its tentacle which curls inside you, fucking you a tad bit slower. The tentacle in your mouth slips out, letting you gasp for air as a broken moan escapes your lips.
Omeluum keeps thrusting inside of you and its body appears to shudder. It moans as well, squeezing its eyes shut. Its brain on either side of its temple throbs as pleasure washes over it. You realize Omeluum is having an orgasm, or at least whatever the illithid equivalent of one is.
When the feeling appears to subside, it pulls its tentacle out of you slowly.
“That was more pleasurable than I expected it to be. My theory appears to be correct. More so than previously believed,” Omeluum says.
“It appears so,” you say as you catch your breath.
“I enjoyed myself. I hope you did as well,” it says as it lies beside you.
“I did. I really did actually,” you say.
“Good. That’s very good. Maybe another theory will lead us to the same place one day in the future,” it says.
“Omeluum, if you want to have sex with me again you only have to ask. You don’t have to attach research to it as an excuse,” you say.
“I can’t believe I’m saying this but I am glad that you said that. I must admit, I would like to explore this more. Research or not, being this close to you is something I enjoy. I seem to…like it,” Omeluum says.
“I like it too. I like you, Omeluum,” you say.
“I am pleased to hear it. I’m not sure how far I can reciprocate feelings of lust or love. It’s not something I am used to. But if I can form friendships, maybe I can form something deeper. Maybe. I’d like to try it with you. And I promise, it won’t be a research project. Unless you want it to be,” it says.
You smile as you turn on your side, giving Omeluum a swift kiss on the cheek.
“I would love to explore this with you, Omeluum.”
