Chapter Text
Usually, you just sift through your mail quickly. It’s always the same stuff; advertisements, unpaid bills, and sometimes messages from churches.
Today though, it’s different. The letter stands out. It’s in a mint green envelope that’s sealed with red wax on the back. You open it curiously, even the paper feels like it’s expensive.
Inside is a normal piece of white printer paper. The words interest you immediately, your eyes clicking onto digits that read $200,000.
You suck in a sharp breath and begin to actually read it.
Dear Y/n L/n,
We got your information from a job application website and thought you’d be a great fit for us. Here at Mintz Lab, we’re running an experiment with demihumans to further their integration into day to day life. We’re offering a total of $200,000 to those that participate. Though we cannot disclose details, the experiment will last over the length of a year with room and board covered during that time at our facility. If you are interested, please call XXX-XXX-XXXX. From there, we will arrange a meeting with you where we can give you some more information.
We hope to hear from you,
Mintz Lab
You read it over again, $200,000?! Room and board included! It sounds too good to be true. Mintz Lab is a legit organization, and you find their signature stamp on both the top left corner of the printer sheet and on the envelope.
It seems legit, but I’ll have to call the number…
The truth is, you don’t have a job right now. You’ve been on several job application websites, so the fact they referenced it has to mean something.
Am I delusional? 200k for a year long experiment, it could be bad though…
But, you’ve only heard good things about Mintz Labs. They’re a major header in the demihuman integration process. Historically, humans and demihumans didn’t get along. Demihumans, are, well, not human. They do animalistic things. They killed humans, but likewise, humans killed them. So, you think (in your superrr expert opinion) that both sides were in the wrong.
You see them around all the time, but communities are somewhat segregated. Demihumans live with other demihumans.
Mintz, however, has been pushing barriers and trying to integrate the two species together. All over the nation, they’ve been pushing for unity and togetherness. Life isn’t the way it was when you were younger, which was, frequent violence between human and demihumans. But, it isn’t perfectly peaceful either. There’s less attacks on both sides and less fighting too, but you wouldn't say zero.
Yet, you just aren’t the same.
But, $200,000, I mean, that’s totally life changing for me, even if it takes a year to get it.
Without further thought, you dial the number and call.
—
The office is sterile. It almost looks like a lab room with how glowing white everything seems to be. It smells like antiseptic too. You guess those conditions have to stretch everywhere to maintain image.
The secretary brought you here, but soon, someone else arrives. It’s an older, tall woman. She wears a dark pink pencil skirt with a matching blazer. Short blonde hair is chopped into a nice, even bob that reaches her chin. She smiles warmly at you and shakes your hand
“You must be Y/n.”
You nod your head, watching the woman sit down. She introduces herself as “Anne.”
Anne intertwines her hands together on top of the desk. “You’re here about the integration experiment, I assume.”
“Yes, I am, but I didn’t get much information on the phone.”
“Of course.” She nods her head. “It’s quite…private, so we require people to come in for it.”
“I understand.”
She clears her throat. “I’m happy to explain. As you read in the letter, you will receive a sum of $200,000, do keep in mind that that requires you to stay at the facility for an entire year. You’ll need to be closely monitored for safety. This, of course, means you’ll be receiving free housing here along with meals and necessities.” She pauses. You nod your head, cueing her to continue.
“Now, the experiment itself…is quite different. We’ve gathered some demihumans here. Some are here of their own accord, but some are not. All those gathered have exhibited curiosity and interest toward human staff. Our goal is harmony between human and demihuman.” She pauses again, wetting her lips. “So, they’re perfect candidates. You’ll get to know them, help them with their cycles, and give them regular relief visits. And, at the end of the year, if you’re able to bond with some, we’d even give you the option to take one or two home with you. Of course, you’d be paid for such a thing, and that would require monitoring too…” She trails off, tapping her chin.
You’re not so focused on the end part though. “I’m not sure that I’m understanding what this experiment actually is. You just want me to…be friends with them?”
“No, it’s not so simple. Demihumans actually have very…complicated relationships with one another. They don’t like other species, but humans are tolerable to almost all of them. We’re unable to get our hands on…multiple of the same species. So, with your help, they can have a faux mate when they need one.”
“You want me to be their mate then?” You know about mates, everyone does. Additionally, some species of demihumans (specifically harpies and arachnids) are known for swooping up humans and forcing them to be their partners.
“In a way, yes. Demihumans have needs that we don’t. We want our demihumans to be as comfortable as possible and we also want to foster healthy relationships with humans for them.”
You’re quiet as you stare at her, mulling over all of the information she just gave you. You take a deep breath and then release.
“If I agree, would I be fully moving into the facility for the year? Like, should I stop paying for my apartment?”
“Yes, we’ll send moving trucks to help you. I’d cancel my apartment payments if I were concerned about money. You’ll be able to bring all of your things here, we even allow pets.”
You nod your head. You don’t have any pets, so it wouldn’t have been an issue anyway.
“I’m in.” You state boldly. You don’t think it requires any more thought. Mintz Labs is reputable, it’s $200,000 including a place to stay, and you haven’t interacted with demihumans much, but you think you’ll be fine.
—
It all happens so quickly. You find yourself settled into the facility a week later. Your things are all unpacked. You’ve been here for three days, and it’s really nice.
Your bedroom is huge. It’s not just a room, you get an entire apartment sized place to yourself that’s way bigger than your old apartment. The fridge and pantry are fully stocked, and you were told it’ll be staying stocked.
There’s a huge flatscreen TV in the living room. Your bed is king sized. The bathroom is giant and it has a bathtub and a shower. You can also peruse around the floor above you and the floor below. The rest requires access cards.
The floor above you seems to be some kind of floor that you can just relax on. There’s two TVs on opposite sides of the room, large sofas, fireplaces, snacks, and more. They said there isn’t anyone else at the facility currently, but when there is, that will be a good place to hang out.
The floor below you is sort of split. One half is a pool room. The other is a small gym. There’s also a locker room down there.
It’s awesome, you feel like you’re staying at a hotel. Today, you’ll be talking to Anne again to discuss starting the experiment. Or, you are starting it. You didn’t really understand the phone call very much.
She knocks on your door and then comes in. You don’t get the luxury of locks, they said they need access to you at all times. And, it is an experiment, so you guess you understand.
You follow her into an elevator she badges herself into. Then, you go up several floors, walk for a while to get into a separate wing, and then enter a room that looks like something you’d see at a doctor’s office.
She instructs you to lie down on the bed and you’re swarmed by two nurses shortly after. They check your vital signs, inspect your body, and then instruct you to get into a gown.
You’re surprised by how quick everything happens, you don’t even get the time to ask Anne the questions you wanted to.
You open the door when you’re changed. Anne makes herself comfortable on the chair in the corner. The nurse told you the doctor would be in soon, and soon enough, she is.
She does some of the same stuff the nurse did, listening to your lungs and heart. She feels your spine too and checks your ears and tongue.
Then, the dreaded moment happens, and, to be fair, the nurses did tell you about it. They were just moving and talking really fast. She pulls out some kind of extension of the bed and instructs you to spread your legs on it.
And, you do it. It’s not really any different than what you’re used to at the gynecological office. The only difference is, she takes some measurements and asks several questions about pain while prodding you internally.
It’s over quickly and you’re told to get dressed once again. Anne doesn’t leave the room and you don’t make her. It definitely doesn’t matter after the appointment she just sat through.
“We’d like to send you to our lamia tonight.” She smiles, looking at you. “It’s important that you’re medically examined intermittently during the experimentation.”
“Lamia?” You repeat. You know what those are, but you can't say that you know much about them.
“Yes, lamia, she’s very sweet. She’s exhibited the most interest in humans.” She nods her head as she speaks, smiling at you.
“Um, what else should I know?”
“Do your best not to reject her. She’s not well socialized, so she might hurt you by accident. If you let her know, she’ll stop.”
“Okay, so just…go in and be friendly.
Anne smiles, but it’s the first time you’ve seen it seem insincere.
---
“If you’re feeling nervous, we can give you something to calm down first.” Anne’s hands are on your shoulders as she guides you down the hallway. You’ve been given different clothes; a loose fitting white dress.
The idea is a little tempting, but you refuse it. “What do I do? I mean…I’m sorry but I don’t feel I’ve gotten much instruction.”
“This experiment is more oriented on what the demihumans want, so just go along with it. Our lamia is one of the sweet ones, so don’t be concerned.” She uses her keycard to open a metal sliding door.
Inside is a huge glass enclosure. There's a small room tucked into a corner with computers in it. Two people sit in there, typing away.
The enclosure is filled with shrubbery. It looks like the outdoors, but it’s artificial. Though, those do look like real plants.
But the enclosure really isn’t the most interesting part. The lamia you’ve heard about has pressed herself against the glass. Her snake tail is wagging slightly, like she’s a dog. She smiles at the sight of you, rubbing her face against the glass.
“This is her? This is her!” She sounds excited, she is excited, and it sort of sends a shiver down your spine.
The lamia wears a dress that’s pretty similar to yours. Her long white hair reaches down her back and she has sharp, golden colored eyes. Her tail is magnificent, a long white color that's looped behind her covered in shimmering scales.
Wordlessly, Anne takes you to the door of the enclosure and swipes her card. She pushes you in a bit harshly and you whirl around, surprised, but the doors already shut. Then, she waves and she goes to the control room with the others.
You stare at the glass, stunned. The lamia’s on you immediately, coiling her long tail around you right away.
You grimace, feeling anxious and constricted from it.
“What’s your name?” Her hand grabs your face as she pulls you against her chest. You don’t think you’ve ever actually seen a lamia before, nevermind being this close to one.
“It’s Y/n.”
“Pretty human.” She replies, rubbing your head softly. “Lilura.” She speaks what you assume is her own name.
Then, she uncoils from you, only for her arms to grab you and hoist you up as she begins moving deeper into the enclosure.
There’s a small area in the corner that looks like where she stays. Blankets are laid down there, and it looks like where she sleeps. There’s little else, and you wonder if this is the right care for her. They’re smart, like humans, so why doesn’t she stay in a place like mine?
She sets you down onto the blankets and then leans down so her face is right in front of yours. She looks at you with widened eyes, turning your head this way and that way as she looks at you. She sticks a forked tongue out, letting it briefly run over your skin.
And, you decide to just stay still, letting her move you around as she so pleases. Soon, she appears satisfied and pulls away.
Her tongue flicks out at nothing as she looks at you. “Little human.” She says passively. Compared to her size, she’s not wrong. Lamias are known to be pretty big though, but most demihumans are.
She extends her arm, placing her hands under your armpits and pulling you to her. From there, she sets you onto her lap, your body straddling hers. Her tail coils only slightly, she seems more confident you won’t be going anywhere now.
She pulls you tighter, making your head rest on her shoulder. You don’t say anything about it. The bottom half of her body feels kind of cold, but the upper half is warm, more reminiscent of a human. The scales have a sort of strange texture, but they’re actually softer than you imagined they would be.
Her hands rub your back soothingly and you find yourself quickly relaxing. If this is what this year will be like…I don’t mind it at all. Really, it’s more of a vacation…
She rubs her head against yours, split tongue not so subtly flicking out to touch your skin again.
You stay like that for a long time, so long, in fact, you find your eyes closing and your body beginning to feel heavy. This is…nice, actually.
You’re pretty sure you fall asleep for a little bit, but you’re jolted awake by your back hitting the ground. Your eyes open, a bit groggy. The lamia hovers over you, tongue sticking out and then returning to her mouth. It seems to do that a lot, like a real life snake, and she is part snake.
“Lilura?”
“Yes, Y/n?” She boxes you in, hands on either side of your face.
You look up at her eyes. They’re a nice, albeit odd golden color. “What are you doing?”
She smiles down at you, and you see her sharp canines this time. You hadn’t even noticed them before.
“Sorry, you were…so relaxed.” Her tail moves, coiling around your leg, but with how close she is, you feel it rubbing between your legs. When you look up and see that kind of smile, you know it’s intentional.
Anne said…’relief’ and ‘faux mate,’ so I shouldn’t be surprised. For $200,000…I’ll be whatever I’m supposed to be.
You actually find yourself a bit curious of the lamia. You think she’s curious of you too.
Her hand grabs the bottom of your dress and lifts it. You sit up, aiding in the process and even taking it off for her.
She beams, smiling down at you. Her hands quickly begin scanning over you, feeling you pretty much everywhere. She begins at the top, running her digits from your shoulders down to your abdomen.
“It’s…the same as me up here.” She comments, hands rubbing your waists.
“I think so.” You agree.
“Not here.” A finger hooks into the line of your underwear.
“No.” You agree again. Lilura looks at you briefly before resuming her exploration. She pulls her finger away, letting the clothing remain on as she pulls back so she can examine your thighs.
One hand grabs each one as she runs them down. Her hands are warm, at least, but you wonder if that heat comes from you. You let her continue all the way down to your feet, which she examines with interest.
You wonder how she’s lived up until now. Humans are half of the population, the other half is an assortment of different types of demihumans. So, the point there is that she really should have seen one of you enough that she wouldn’t be this curious.
Her curiosity is sated soon enough and you watch her passively, not really caring too much about what she’s doing.
Until you do.
Lilura pulls her loose dress off. Beneath it, she’s chubby and curvy. She doesn’t wear a bra, so you see her soft, round breasts. The scales of her tail slowly fade into a human kind of skin. You examine her with some level of curiosity, looking her up and down, but she kind of looks the way you anticipated that she would.
Where you think would be your own reproductive anatomy, she has a long slit. You think that’s actually the outside of it, but you can’t really tell and you feel creepy looking at her like that.
She tilts her head, watching your own curiosity before reaching forward to remove your undergarments. You just sit there, shimmying slightly to help her remove your underwear.
Now, she examines you with fascination. Her hands grip your breasts, squeezing softly. But, ultimately, Lilura doesn’t find they’re much different from hers.
Then, her hands are on your thighs and the force she pulls upwards with causes your upper body to hit the blankets beneath you.
Her fingers are touching you instantly, circling the outer folds. She moves her face close, tongue flitting out with a slight noise. She doesn’t lick you, only seeming to let it have curious contact.
Then, without any kind of warning, she pushes a finger into your opening. A sharp noise leaves your throat, and she pauses to look at you, eyebrows furrowed. She pushes it in as deep as she can, and you don’t complain because you’re getting paid to let her.
She pulls her finger out, eyes focused on you as she leans down to press her body against yours.
“You can be my mate then.” She states, staring intently at you.
And, you aren’t sure how she came to that conclusion, nor why she said it. Your eyebrows knit together in confusion. Before you can ask why, she’s kissing you sweetly. It’s gentle and soft, forked tongue poking at your lips for permission before pushing it further. You open your mouth to her, accepting it. It feels strange when it mingles against yours, but nice in an odd way too.
She grinds her…hips? (Does she have those? You can’t quite tell, at the very least, they’re not the same as yours).
She pulls away from the kiss, lowering her body. You feel her tail moving, coiling, lowering down your leg, but not removing.
Soon, she’s pressed flush against you, and her body feels especially heavy where her chest presses against your own smaller one. Her tongue flicks out again before retreating into her mouth. You can’t help but think that she seems to do that a lot.
She uncoils her tail completely from you slowly. It’s insanely long when you look at it, but when she was ‘standing’ earlier, some was on the ground and some was holding her up. So, it sort of gave the illusion it wasn’t so long.
She rubs her lower body against yours, humming contentedly when she does it. Her eyes find yours, hands moving down your body to feel up your waist.
She kisses you again, and it’s gentle and sweet. It’s not bad at all. This is easy. I can’t believe they’re gonna pay me and cover my living expenses.
“Ah!” You yelp at a sudden feeling, craning your neck to try and look down. At first, you were sure she shifted her tail up to poke at your slit, but when you look away from her and see her tail is behind her, you know it’s not the case.
Lilura tilts her head at your reaction. “Do you want to see?”
“Yeah.” You answer.
She moves close, kissing you on the forehead before sitting up. You sit up too. There, you find the source. From the slit that you saw either is an erection of some kind. You know it’s her dick, but it doesn’t quite look like a human one. It’s longer (bigger too) and the base is scaled, matching the white scales of her tail. It fades in the way that her tail to waist does, but the rest is the same flesh color as her skin. The tip is a weird shade of pink you’ve never seen on a cock before.
Lilura looks away from you, appearing a bit flustered. She bites down on her lip, avoiding her gaze. “I can mate you this way.”
“That won’t fit.” You state.
“Oh…” She trails off, still refusing to meet your gaze. “It doesn’t have to go in…all the way.”
You only reply by lying back down on the blankets. From your position, you’re able to see her grin at your compliance. She returns to the position the two of you were in before. She bends slightly so that she can keep her face over yours. Another gentle kiss is planted before her cock is pressing against you.
And, despite what she said earlier, she pushes forward as far as possible. The feeling leaves you writhing underneath her, audibly complaining.
Anne says to try and do what she wants, but holy shit.
“U-ugh, ow, fuck, ow.” The complaints leave your throat. And, it hasn’t even really started yet, but tears are already prickling at your eyes. She feels strangely wet inside of you, but you didn’t see that when you were looking at her.
Lilura is stuck in her own pleasure, moaning softly above you, complimenting you. She moves upwards. The tears that were building start falling down your cheeks.
She rests her head higher, this way, her neck is completely covering your face.
Then, slowly, she begins to thrust into you. Each movement is accompanied by a moan from her and a cry from you.
“Not so deep.” You’re quick to complain, tears sliding down your face alarmingly. You're sure you can feel her pressing against your womb.
Though Lilura seemed concerned about your wellbeing before, she doesn’t have that sentiment anymore. She thrusts deeply, but slowly, eventually settling into a rhythm that she seems to enjoy. Her hips thrum rather than thrust, so she doesn’t even pull back all that much.
Your complaints are muffled by her soft skin as she continues pounding her throbbing appendage into your tight opening happily. Sounds of pleasure leave her throat and various compliments are thrown in your direction. Her voice is soft, undemanding, but her body is the opposite.
Soon, the sensations begin to culminate. For you, it’s far too much and your hands press against her body, pushing, but she doesn’t go anywhere at all. Lilura quickens her pace, arms wrapping around you tightly to stop your useless struggle.
“Take it all, take it all…” She whispers the words out above you. Your walls twitch around her, or, perhaps, she’s the one twitching.
It all happens at once, a loud, whining sort of moan leaves her throat, her appendage twitches violently, and almost searing hot liquid leaves her. You cry out in reply, human cum is not that hot. It doesn’t burn, but it comes as a shock. Your back arches, walls convulsing around her.
She relaxes on top of you, pressing her weight down. Your struggles are muffled against her. She’s way too heavy to be doing that. You swear you hear your back pop before she lifts herself up, seeming to realize she shouldn’t have done that. She pulls her now flaccid cock from your cunt slowly. You feel the liquid that rushes out drip down onto your skin and presumably onto the blankets below.
“Mhm…” She huffs, pulling down to be face to face with your tear streaked expression. Her tongue flicks out with intention this time, licking up the tears that have been left behind.
“It’s really good, I’m sorry.” She nuzzles her face against yours. “Sorry, sorry…” She mumbles, continuing to nuzzle into you. “I have to…do it again.”
You bite down on your lip in distaste. “You don’t…have to.”
“Yes, yes…” She hums, voice mellow. “I don’t want you to go, and they’ll take you, so I have to. Can’t…”
Her cock hardens again, you feel it on your leg. She returns to the same position she was in before, with your face pressed into her neck.
“Gentle, Lilura, please be gentle this time.”
“I am gentle.” She actually hisses, the only show of aggression you’ve seen from her. Her tail snaps around your legs, coiling tightly. Her arms are quickly around you again. This time, she stays as close as possible. It feels like she’s destroying your insides with each thrust, but all you find yourself able to do is whine into her skin.
—
You find yourself completely wrapped up by her when you awake in the morning. Almost her entire tail is coiled tightly around the bottom half of your body. Her arms hold onto you tightly, and her head is nuzzled snugly into the crook of your neck.
Furthermore, your body hurts terribly. Lilura didn’t stop. You don’t know how many times she did it because you really aren’t sure yourself. Strangely, she rested between almost every round, shutting her eyes and coiling around you for around half an hour each time (you estimate) before getting up and going again.
You keep your mind focused on the prize, the $200,000 you’ll get at the end. It’s hard, it was really hard last night and you found yourself asking- no, begging her to stop.
Her personality seemed sweet, but you’re not sure that she actually is. Anne referred to her as ‘one of the sweet ones,’ so you find yourself way more nervous for whatever comes next.
One year…$200,000, no bills to worry about, no rent to worry about.
Even though the soft flesh of your womb is stinging painfully and your thighs are beyond sore from Lilura’s prodding and pulling, with the awareness of what you’ll get in the end, you can soldier on.
