Chapter Text
Brendan's life was about to change forever. He was sure of it.
'How could it not?' The young adventurer thought to himself, a wide, eager smile spread across his handsome face as he made his way up the rocky hillside. It was a gorgeous day in the Sword Mountains, clear, blue skies with not a hint of foul weather on the horizon, the last legs of Summer as the season began to drift into Autumn. Birds were singing, the wind blew softly, and everything was just...pleasant. It was this day that Brendan had decided to set out for the underground ruins he had learned of not even a week before, ideas of untouched riches dancing around in his mind. He'd been on the road for a year now, a young man of twenty-two who decided farm life wasn't for him and took to work selling his sword to anyone who needed a hardy hand in defending their town from goblins or tracking down bandits. It had been good, and he had made decent money, but if he wanted to really make a name for himself he needed to get serious about equipping himself for tougher challenges. His fathers old sword was serviceable but old and worn, but his armor and shield weren't quite awe-inspiring. But this would change that. 'If this place is as filled as that old herbalist said, I'll be able to get all new armor. A new shield!' He grunts, hefting himself up over a large rocky ledge, stopping for a moment to take a swig of water from his canteen. 'A horse, even!' The idea of not lugging around everything on his back was propelling him maybe even more than the prospect of a new breastplate or a new longsword. Not as if he couldn't handle it; working all of his life on a farm had blessed him with a strong back, broad shoulders, and a firm, toned chest. Still, having a mount to ease some of the burden wouldn't be too bad, and his mind was filled with ideas of what kind of horse to buy with his new treasures, what name he might give it. So distracted he was that he almost missed the mouth of the cave that he had been told of, berating himself for a moment as he sets up his rope and ground anchors. He had remembered the warning from the old herbalist about the depth and darkness of the cave, of the dangers within. Of the difficulty he would have if he found himself trapped down there. So he went as carefully as he could, making sure to put new anchors in the walls and the ground as he descended from the mouth of the cave into the deep darkness.
It didn't take long before he found himself needing a torch, having to move even more slowly now that one hand was occupied. But eventually he found the bottom, bright green eyes growing wide with wonder at the sight before him. The cave seemed to have led into a cave-in, a portion of this old ruin's roof that had collapsed. He placed his lit torch in a nearby sconce, lighting a second one and leaving the first. A scant bit of light from the surface was shining down, just enough for him to see the rope left in a tidy bundle. If nothing else, he'd know where the exist was once he found it. Using a handy trick a friendly Dwarven miner taught him (an additional thanks for when he helped clear out a giant rat infestation), Brendan began to mark the halls he walked with an arrow of white chalk on the left side, though he soon discovered it might not be as necessary as he though.
Only a few hallways in and the curious adventurer found himself in a large antechamber, staring in amazement at what seemed to be ancient Elven ruins. The murals on the walls had long since faded but still had some color, and while the ornate architecture was old and worn, everything seemed to be holding up quite well. Brendan sighs, looking around for a moment before placing his pack down on the ground, setting his torch a few feet away as he begins to unpack his essentials. If this place was as large as he expected, it'd be a smart idea to leave some of his things here, his bedroll and cooking pot and the like, to make room in his large rucksack to hold whatever treasures he found. It was at this point that his eyes found themselves drawn to something in the corner. A round thing, pale white in color. He took up his torch with one hand, the other moving to the hilt of his sword, stepping to the thing. With each new step it grew clearer, more visible. It was a skull, a humanoid skull. And the back of it was missing. Before the poor would-be spelunker had time to react he felt the energy collide with his body, locking his joints and muscles. He couldn't move, dropping to the ground with a hard thud. His mind was racing, heart hammering in his chest, struggling as best he could to break free from whatever magic was holding him. The sound of heavy footfalls grew closer as a shadow began to grow on the wall in front of him. The last thing he felt before unconsciousness claimed him was a painful shock of energy.
Mey'zathon let out a rather disappointed sounding sigh as the humanoid in front of them dropped to the ground, slender arms crossed in front of their chest as they step around to the front of the person. They looked down at him, studying the things figure before shrugging and waving a hand to lift the human up. 'It will have to do.' they thought to themselves as they casually strode back to their laboratory, navigating the secret passages of the underground ruins all the while making sure not to let the paralyzed body hit anything. They needed this one healthy and uninjured. Humans especially were far more cooperative if treated properly. Once they had reached the entrance to their working chamber Mey'zathon guides the unconscious human to the large bed where the straps had been built, a small tadpole pool at the front of it. With practiced ease they work at stripping this human of its- his armor and outer gear before removing his upper clothing.
This one was, as they had learned from reading human literature, quite attractive by human standards. The mans face was young, no beard or mustache, with a head of thick and curly brown hair. Tall, only a couple of inches shorter than the illithid, and well built. Muscular arms and broad shoulders, but not like a hulking brute, and his form was mostly smooth and free from body hairs. The muscles on his chest were large, though they were quick to determine that it was simply well developed muscle and not fat like the female humans had. A bit of humor found its way into the creatures thoughts as they observed that this human was built quite like a working animal, muscle and fat tissues both where they were needed and in the right amounts. They found themselves trailing a long, slender finger down from the humans collar to his pectoral, giving it a curious squeeze and finding that maybe a male would be just as suitable for their needs. The thought lingers for a moment before the illithid goes to work preparing the specimen for what was to come, securing the straps and bindings before heading over to finish their own preparations.
Brendans body woke before his mind, back arching and hips bucking as he sucks down a deep lungful of air. His eyes open wide and he looks around, head moving as best as he could make it. The first thing he noticed was that he was bound to some kind of...bed? Stripped to his trousers with some kind of thick leather holding his limbs out by their wrists and ankles. The second thing he noticed was that he was in some kind of underground...something. It was foreign to him, this architecture. It looked Elven but not quite. There was ample lighting thanks to a large chandelier and a fireplace against one wall, seemingly venting to the outside, and there was an odd painting above it. A few more seconds passed before it clicked that this must be Drow dwellings, realizing at the same time why the ruins must have been left untouched. He wasted no time in struggling, tugging against the bindings.
"Please stop. This will only tire you and I need you in fit condition."
Brendan's eyes snap open wide, quickly searching for the source of the odd voice. It was...not human. It had an odd cadence, like it was not used to speaking Common.
"Hm, enough intelligence to obey commands. This is good. Very good. Human, do you have a name?"
The fighter tenses up, growing more concerned that he couldn't find the source of the odd voice. There's a moment of hesitation before he speaks. "...Brendan. Where am I? Why have you captured me?"
At first there is no response, no voice to meet his own. Then he hears footsteps, and sees the light of a candle approaching. And then he sees what he immediately understands to be his captor.
A Mind Flayer, an illithid. A creature of the Underdark, spoken of in tense tones by seasoned adventurers. Tall, over six feet, with a slender indigo toned and muscular body that had a vaguely masculine shape. Oddly, it was also nude save for some thin flowing garments on its lower half. The illithid stares at him, large deep green eyes fixated on the human, its facial tendrils covering its wicked beak.
"Brendan...Brendan..." It was as if the thing was testing out his name, a few clicking sounds following its speech. "Human names are so...odd."
The man on the bed swallows nervously, dread filling him as he watches the terrifying being step closer, the candle held up to illuminate its face. He didn't know the process, but he knew what happened to people who were captured by mind flayers. Most never came back. This sense of fear seemed to be present on his face, Mey'zathon 'chuckling' as they step even closer, now standing beside the bed.
"No doubt you have heard of my kind? Know of what we do?" The fearful nod from the human was enough confirmation for them. Mey'zathon sets the candle down on a small table beside the bed, content to stare at their specimen for the time being. "Good, good. Your intelligence pleases me. Though in this situation I fear that your knowledge of my kind might be..." There's a pause, the illithid beginning to slowly walk around the front of the bed. "Less pertinent."
Brendan swallows, fear filling his senses as the monster toys with him, confused as to why it was being so...polite? He knew from the stories they were wicked smart but "good conversationalist" generally wasn't part of the description. Mey'zathon seemed to sense this, stopping once they were on the other side of the bed, staring down at the man. "You are wondering why I am speaking to you?"
Brendan stares up at the other, nervously nodding.
"You can speak, can you not? Or do you know only those few words?"
The question genuinely surprised him, the shirtless human blinking a few times before speaking. "I...I can speak, yes."
Mey'zathon smiles, or does as close as an illithid can to it. They clasp their hands together and nods. "Good, good. Speaking is good. Now, human. You currently wear a rare badge of honor. You see-" The mind flayer begins to walk again, gesturing around their laboratory as they slowly circle the bed. "I am...let us use the phrase 'outcast'. I am separated from my kind, though not entirely by my own choice. I study you creatures. Humans, elves, dwarves, orcs. I study how you work, your physiology, your insides and outsides. I find it all...fascinating. Fascinating in ways that many of my kind do not, and indeed many of my kind dislike my fascinations." The tall illithid stops at the foot of the bed, staring down at the human, watching how he breathed. How he moved. Their eyes following a bead of sweat trailing down Brendans body. "You might say I am something of a scientist in this regard."
Brendan was terribly confused, not sure of how to process any of this information. Why was this creature, this monster of legend, speaking to him as if he expected him to retain any of this? Wasn't it just going to eat his brain?
Mey'zathon pauses, seeing the look of confusion on the humans handsome face. "No doubt you are aware of what my kind usually does to our captured prey. We have our 'nickname' for a reason, after all. But do not worry, human. This will not be happening to you." A strange desire to laugh fills the illithid at the quite obvious look of relief on their human specimens face, allowing him this moment before continuing to speak. "Human, Brendan. Are you aware of how illithids breed?"
Any sense of relief that the young man felt at learning that his brain wasn't to be eaten immediately vanishes. Fear grips him, body tensing up as his green eyes widen and lock on to his captor. Mey'zathon waves a hand, stepping closer to him now, walking up to stand beside the front of the bed. "Ceremorphosis. Our tadpoles, which we lay clutches of only a small few times in our life, are put inside the head of a humanoid. They burrow in, through the ears or the nose or the eye, and devour the brain while taking the place of it. As you can imagine, this is terribly inefficient. Not only is it not guaranteed to work but it requires us to capture a host for every single one! Can you imagine the work involved?"
Brendan, in fact, could not. He couldn't imagine much of anything right now, mind simply too focused on the fear he felt. Dying was one thing, but...being turned into one of those things? He had gone pale, wetness growing around his eyes, trying his best not to let his terror overtake him. If Mey'zathon noticed any of this they didn't acknowledge it, simply continuing with their explanation as they slip closer, leaning over the bed to reach a hand out to stroke the fearful humans forehead. "However...I have endeavored to find another way. As I've said, the process of ceremorphosis is terribly inefficient. Why go so slowly? Why take so much time?"
Even in his fear, Brendan found himself confused. Confused at the way the mind flayer spoke to him, confused by the way it was touching him. And having seen it walking around the bed, he was growing more confused at the way it walked. As if there was something wrong with it.
The illithid strokes the humans forehead, a finger trailing down his cheek, their eyes locking with the mans. "I decided...why not study how the creatures we use do things instead? You humans in particular are exemplary breeders, very efficient! Why, you seem to do it for fun!" Mey'zathon lets Brendans face go, striding over to a large desk covered in books and scrolls, picking one up to show what was clearly an illustration of a pair of humans making love. "And the speed at which your young grows to maturity is far better than many others. So, as I studied your breeding habits I realized something wonderful. We could use you to breed young that wouldn't need a separate host! Imagine the possibilities!"
As the illithid explained all of this their human captive slowly grew from experiencing the terror of death and transformation to another concern entirely. This thing was talking about not putting some kind of slug in his head to take over his brain, it was talking about sex. Sex, Brendan realized, with him.
Mey'zathon was quite pleased with themselves, setting the book to the side to pick up a few scrolls containing medical diagrams. "I have spent decades studying this. It is why I was forced to leave my kind, they rejected my ideas. Called them 'barbaric' and 'grotesque'. They are small minded I say, limited themselves to only what we know to work and never thinking of what could work. It took considerable testing, finding ways to make this happen. I have...changed myself, my body. Equipped my biology with the necessary means to carry this theory out." Brendans eyes go wide as they watch the mind flayer undo their garments, letting them fall to the floor to reveal their lower half. Between the things legs was some kind of slit, the illithids hand reaching down to gently tease it, coaxing out a...
"Cock..." The word left the humans lips as a soft, fearful whisper, his green eyes transfixed on the steadily emerging organ. It wasn't like his own; it was slender, dripping fluid, with a tapered point for a tip instead of a wide head. And it was long. And moving. The illithid seemed to 'grin' from behind its tendrils, stroking their squirming shaft as they grunt, shuddering some before a second, more 'human' cock emerges as well.
"Obviously there were difficulties as first-" Mey'zathon grunts again as they begin to walk back to the bed, stroking both of their organs to bring them to their full size. "I tried simply laying my clutch inside of a specimen at first. It ended poorly. Then I had to find ways to encourage my body to produce more clutches, so that I may test more. You are the eight specimen I have obtained for this, and I believe you will be the first of many successes. The difficulty, as I discovered, was that the tadpoles were not absorbing the necessary nutrients from the brain. They would grow inside of the specimen just fine, but nothing would come of it. But I believe I have settled upon a solution..." The illithid slips up onto the bed, kneeling between Brendans legs as their hands move to his thighs, taking in the humans form before looking into his eyes. "The brain will still need to be part of it."
Brendan, having been too locked between fear and confusion to really respond to any of this, immediately realizes the implication. He begins to squirm, shaking his head and trying as best as he could to free his arms or legs as he begins whine. Mey'zathon makes a soft clicking sound, shaking their head as they slip up to straddle the humans lap, their dual cocks laying on his toned midsection. "Do not worry, human. I need you alive and healthy for the breeding process. I just need to make you more...malleable."
The scared human watches as the mind flayer reaches out, hands slipping up to either side of his head. He could do nothing, stop nothing. He stammers out requests for mercy, shaking his head and trying to pull it back. "Please no, please, just let me go, just let me-"
Everything goes blank for a second. Like his mind went dark before waking back up. A strange sensation fills him, fills his head. Like water in the ear but...more. He was dizzy, vision fuzzy. Everything felt...odd. But not bad.
Mey'zathon's hands stay beside the humans head as the magic does its work. His mind needed to relax, in more than one way. Brendan didn't know how long things went this way but eventually he felt his senses mostly return to him, blinking and looking around with a heavy head. It still felt like he had water in the ear, but that sensation encompassed his entire head now. "Wh...what..?" The word came out mostly slurred, a bit of drool dripping from his bottom lip. The illithid looked pleased, clapping their hands again before slipping off and kneeling beside the humans head.
"Good! It seems to have worked. I will not bore you with the details- mostly because I do not believe that you are capable of understanding them at this point, but-" The illithid gently places a hand on the other side of Brendans head, holding it in place as they ready themselves. He feels a warm, wet touch on his right ear, fluid gushing out to coat it, a sensation of something pushing at the small hole following right after. "I assure you, this will feel...good.
Pressure. Gentle but firm pressure. Constant. Pushing at his ear. Pushing to get in. And then...pop. A wet, squelching sound as the illithid works their slender ovipositor into the humans ear. Into his head. There's a chittering cooing sound from Mey'zathon as they slowly push in, the wet, squirming organ making its way inside with surprising ease. Brendan gives a weak gasp, eyes fluttering and body shuddering as his head is truly, literally fucked. There was some strange creatures cock in his ear. In his head. And...it felt good? He was swimming in a fuzzy fog of abstract pleasure, unaware that his eyes were rolling back and that his mouth was open and drooling. Or that his own cock was hard. The feeling was strange, like he shouldn't be experiencing anything. But he was.
The illithid grunts and continues to push in, steadily going until their hips were pressed to the side of the humans head. They move a hand to gently pet the moaning mans cheek, a finger slipping into his mouth. "Good human. See? This is good. You like this, don't you?" The weak, mindless moan from the man sent an unexpected sensation through the illithid, their cock throbbing above Brendan's face. Truth be told this was...not what they were expecting. This was the first real test of their theory and they were quite pleased at how much they were enjoying the novel sensations.
The words were entirely lost on Brendan. The poor human was experiencing things that the human body wasn't quite designed to experience. Every squirming wriggle from the slick ovipositor sent electric pleasure through his body, the mind flayers spell having created not only the suitable habitat for their tadpoles to grow in but also a web of over-active pleasure centers. He groans around the finger in his mouth, tongue mindlessly licking at it. This drew a curious feeling from the illithid as they stared down at their specimen. Technically nothing else was required of them, simply needing to wait until they laid the first of their clutch. But...well. They studied human breeding, right? They knew what it mostly comprised of. So, with a gentle grip on the humans head, they drew back and thrust in.
Brendan came. He cried out loudly in pleasure he never knew he could experience, eyes glazed over and fluttering as his hips bucked and cock gushed. Mey'zathon was shocked, eyes widening as they watched the hot seed gushing out through the mans trousers, their own shaft throbbing in kind. Their finger gently thrusts in and out of the mans mouth, playing with his tongue, stopping when they feel the mind-fucked human under him begin to suckle on the long digit. Mey'zathon pauses, not expecting to feel such...elation, at this. At the needy, submissive act. Now, more than any other time they had attempted to mate with a human, they felt lust. And that provocation of lust would not go unrewarded.
Brendan mewls weakly as they suck on the finger, mouth opening wide as a second one slips inside. He was barely cognizant of anything else as the creature beside him steadily fucks his ear, his head. His mind. With each thrust he was growing more and more calm. More at ease. Happier. Pleasured. Eventually he was reduced to drooling around the gently thrusting fingers, an expression of blissful, joyful stupidity spread across his handsome face.
Mey'zathon never did more than shallow thrusts, simply desiring to reward their specimen at this point. But it wouldn't last long. They could feel their clutch. Their brood. They stroked the humans face, pushing themselves in to the base as Brendan moans. Without another word they shudder and let out a chittering grunt, the base of their ovipositor swelling out as the first small tadpole begins to move down it. The humans eyes widen, feeling the pressure, almost as if they realized what was happening until it pushed inside. He shudders again, eyes going glassy and unfocused as the illithids special brood was deposited in his mind. Not all of it, of course. Only a few, less than half a dozen. And they wouldn't stay permanently, just long enough to absorb what they needed. To take their fill of this humans psychic energy while their small bodies adapted to their temporary home. After that they would become the catalyst for the proper breeding.
After the fifth tiny spawn Mey'zathon pulled their ovipositor out with a wet squelching sound, shuddering as it gently flopped down onto the humans face. "And now the...initial insemination..." They were beside themself, not expecting to take so much pleasure in the act. Their other hand moved to wrap around their cock, lowering it to the freshly emptied ear. For a moment they expected things to work on their own, forgetting in the moment that stimulus is required for this. They move their hand to their shaft, stroking it a few times, pressing the tapered head against the wet ear hole. It felt...good. Pleasure. Physical pleasure filled them. And then the human moaned.
Mey'zathon stopped, looking down at the human. At his mind-fucked expression of dumb joy. At the way their face twitched from the activity in their head. The illithid gently takes hold of their specimens head, holding it in place as they begin to push their cockhead at the wet ear. Watching as Brendan's eyes widen, mouth forming a wide O as the mind flayers cock pushes into his ear. Mey'zathon gives an unexpected groan, the tight, wet hole gripping them firmly. They shudder, taking a moment to adjust before beginning to thrust in. The human squeals out a loud, mindless moan as his ear is fucked, gasping and panting as the cock pushes in and out. Deeper and deeper. Thrusts growing firmer. Soon several inches were pushing in and out of his head, truly fucking his mind. And oddly...everything was fine. Whatever spell that had been done to his head had seemingly made his malleable enough to allow for the inexperienced fucking.
This wasn't the first time they had done the act, but it was the first time that the illithid had done it because they were enjoying it. Because they wanted to feel the pleasure. It was alien to them, and like any alien knowledge presented to them, they had to know it. Had to feel it. Their thrusts growing quicker, more eager. Wet squelching filling the room as they fuck their hard shaft in and out, fingers stuffing back into the humans mouth. The mouth was...intriguing. Hot and wet and soft. The sensation on their fingers was...enjoyable. "I must...experiment with this hole later..."
Brendan barely reacted to the words. Everything was fuzzy. All sensations were pleasure. He drooled around the fingers, his cock throbbing and as he mindlessly orgasms. Everything that his brain could focus on was being replaced by the cock thrusting into it. Fucking it. Mating with it. And then he felt it. Felt the thrusting stop, the cock swell. Vaguely heard the mind flayer growl out before he felt the rush of hot, thick seed. It filled his head, soaked into his mind. Flooded his thoughts. At first it was only physical, the illithids release large enough to fill his head after only a few gushes, the sticky, viscous purple cum seeping out of his ears first and then from his nose and the corners of his eyes. And then it began to truly overtake his thoughts. He could feel his mind relaxing, floating on a cloud of pleasure. With each gush of hot, sticky mind flayer cum Brendan's intelligence drained, washed away with pleasure. He didn't need to think. Thinking wasn't worth it, anyways. Look where thinking got him. He just needed to feel good.
Mey'zathon grunts and shudders, holding themselves inside of the humans head for the majority of their orgasm before pulling out and, acting purely on instinct, pushing back in to the mans mouth. They groan in pleasure at the sensation of the hot, wet hole around their cock, unloading a few more gushes of seed into the mans mouth and then his throat. They pull back, panting softly as they watch the handsome human gurgle and moan, thick purple sperm dripping out of every hole on his head. A new sensation filled the creature, renewed lust filling them as they watch their seed and spawn sap the humans mental clarity. This step would take time, an hour or so for the first part depending on the humans raw intelligence. And then they would begin the proper breeding.
