*NSFW* 'Till Death do us Part (Yandere!Parasite X GN!Reader)

CW: Sexual non-sexual penetration, forced masturbation, mind control/break, unhealthy relationships, yandere behavior, dead dove

This ended up a LOT longer than I had planned, emotionally attached to this non-human yandere ❤️

The Albtu required intelligent hosts in order to live. It wasn't just about survival. To be trapped in ones own body, it was torture. They could not think, could not act, unless they attached themselves to a living brain. If they infested an animal brain, then the only thoughts the Albtu could produce would be primal, forcing their animal suits to find food and housing for their young. But to be in the mind of a human.. it was both heaven and hell. To understand the world around them, truly understand, thinking on a much higher level of existence than their siblings or parents, to experience all that life has to offer, was a miracle they never would have known about had they not been privileged enough to be born in a human. But on the flip side to that coin was experiencing fear. Not the fear of being trapped in a deer coming face to face with a mountain lion, smelling your own demise, but listening to the horrified screams of the original owner of their new body, forever. Learning that the humans they took over were still conscious, kept prisoner in their own minds, forced to watch the Albtu living their lives was a nightmare for the creatures who had only just learned what compassion and empathy was. The existential horror that was knowing that you were nothing but a parasite, and the guilt they felt.. it was too much for many of the Albtu to handle.

For the Albtu who became the human known as (Reader), existence was a bittersweet agony it could neither explain nor fully understand.

It was born into this life in the host of a stray cat, knowing nothing but pain and hunger. It didn't understand what a car was, or why the loud creature charged at it, ramming into it and causing a pain that never went away. Everything hurt all the time, and it couldn't even understand why.

Then, one day, it met warmth. A human, with gentle hands and a soft voice took the time to earn it's trust. They didn't know it was in pain, but their touches were delicate all the same. The human gave it food, and although it didn't have a human's intelligence or concept of identity, it did feel trust and companionship with the human who cared for it as though it was their kin. But the pain grew, and it could feel it's death was approaching. And as an animal, it acted as a dying animal would.

"There you are, baby!" (Reader) called out to their little stray friend, finally finding it hiding under a porch. They laid flat on their front, arm stretched out as far as possible towards the small bundle of fur, and quietly clicked their tongue and wiggled their fingers. "Why're you hiding, baby?"

The cat gave a warning yowl, in too much pain to bat the human away. (Reader) took off their coat in an attempt to flatten their body, and squished themselves into the small space to close in on their kitty.

"C'mere baby.." The adult whined as they continued inching closer. When they finally got far enough under the porch to touch two fingers onto the matted fur of it's thigh, the cat cried out in pain. "What's wrong?!" They recoiled their hand, but only to writhe faster and more frantically towards the animal whose breathing was slowly turning ragged. (Reader) placed their face close to the kitten's, tears building in their eyes as they tried to keep their heart rate steady, hoping that the cat could feel their attempt to soothe it in it's possible final moments.

"Hey, baby... I'm here..." They whispered into the tawny kitty's pink little nose.

It was then that the Albtu's primal instincts morphed from the need to hide during it's death, to a fight for survival. It couldn't survive for long outside of a host, a few seconds at most, the transition needing to be nearly seamless. The cat howled in pain, as what appeared to be a black, semi translucent single celled organism the size of Reader's palm, shot out from it's nose, thrusting itself into (Reader's) nose before they could react, and quickly slipping through impossibly small crevices in their anatomy, slinking in a fluid like state till it reached their brain. There was an electric shock that pulsated throughout (Reader's) body, then they were no longer in control.

The Albtu became self aware the moment it took hold of (Reader's) brain, which was immediately followed by the realization of what it had done, the betrayal towards the only human who had ever shown it kindness, and the remorse caused a physical agony in it's stolen heart, screaming while clawing at (Reader's) shirt.

It howled until (Reader's) throat was burning, and it felt as though it would succumb to exhaustion next to their previous host's dead body.

Outside the neighbor's porch the sun had begun to set, but the body thief hadn't moved, too broken hearted to find the will to live after it had stolen (Reader's) body to do just that. It could hear it's own internal monologue for the first time, and found it far too loud and intrusive. Although it could feel memories that were not it's own, it didn't push further into the brain out of respect for the person it betrayed.

[Hello?]

It's breath hitched, thundering heart beat overtaking it's previously drowning thoughts. Like an auditory hallucination, it heard the human's voice, not from behind it, nor from deep inside like it's internal voice, but inside it's ear, like (Reader) hadn't been possessed, but shrunk down to the size of a flea and was hiding in the safety of it's ear.

[Am I dead?] Their voice was so sad and small it made the Albtu cry once again.

"No. No, but you are no longer yourself, which may be worse. I'm- I'm so sorry..."

[Are you a ghost?]

"I don't know what that is.."

[What are you? I can't move my body.] Their voice wasn't scared, but numb. The whole situation was so outlandish it was almost dreamlike, unbelievable.

"I have no name. All I know, is that I am an Albtu. The word echoed in my mind even when I was a mindless cat."

[... You're an alien?]

"I do not know."

[How can you speak my language?]

"I know it as it was an ability of yours, like muscle memory, you do not need to focus to speak it, therefore I can speak it."

[What does that mean? Are you inside my head?] Waves of guilt crashed into it's consciousness, and (Reader) was able to feel it. [...why me?]

The Albtu explained everything, from the moment of it's birth, hatching already inside the cat, to the moment (Reader) found themselves in the passenger seat of their own body, including why it didn't probe into (Reader's) memories. "I am so sorry.. your's is the only love I have ever felt in my life, and if I was who I am right now, I would have allowed myself to die instead of latching onto you. Now, even if I leave your body, it will leave a permanent hole in your brain, and it will kill you."

(Reader) went silent in contemplation, finally coming to terms that this was not a dream, but still unable to force themselves to be angry at the alien inside them. They could feel it wasn't lying to them, feeling it's emotions stirring in their brain alongside their own feelings. A strange excitement bubbled out of the kind little human.

[We can make this work!]

"What?"

[We can make this work! You just manually act out what I would want to do, and we can discuss how to move forward so we can both continue to live fulfilling lives.]

A heat krept over it's face, heart swelling at how kind it's human was. "I don't deserve your kindness. But I thank you, and I will do my best to help you continue live as normal."

[My name is (Reader). That's what you'll have to respond to, but I need something to call you.]

"..I can't verbalize it, but I knew you would repeat a word often to me when I was the cat. Was that a name?"

[Oh, yeah, but you were a kitten, so I called you baby. We can't name you Baby, because that's also used by humans as a nickname between lovers.]

"Oh. Then, could you name me something? I don't know any names other than yours."

That was how the strange partnership, and friendship, between the human, (Reader), and the parasite, Baby, began.

Although (Reader) gave permission to Baby to enter their memories, it refused, still recovering from the unintentional treachery it had already committed against (Reader), so instead (Reader) acted as a teacher, guiding Baby as it learned about the world. And just as they had promised each other, they made it work, Baby happily making memories of it's own as it acted as (Reader), going to work for them and helping keep their life as "normal" as possible.

"What's going on?" Baby pointed at the laptop screen, a scene of a wedding playing on the soap opera (Reader) was watching.

[It's a wedding. Maria and Alonzo are getting married.]

"What is married?"

[Marriage is when two people who love each other very much decide they want to spend the rest of their lives together, so they have a party called a wedding to show their friends and family how much they love each other, and promise to love each other forever in front of everyone they know. Ah, but sometimes marriages don't work out, and people fall out of love. When that happens they sign a piece of paper for the government to swear that they will stop living together as lovers, that's called 'getting a divorce'.]

"Why do they 'fall out of love'?"

[A lot of different reasons. Sometimes, people hurt the ones they love, and their spouse can't forgive them, which causes love to die. But sometimes, it just... happens. Humans change as time goes on, and sometimes the person they become isn't compatible with their spouse anymore; sometimes people hide a part of themselves, intentionally or not, when they meet someone they like, and it only comes out after the get married, and their spouse realizes they don't actually like the real them... It's complicated. There are a lot of reasons.]

Baby focused on the intricate ritual on the screen, the two main characters placing rings on each other.

[Those are wedding rings, to show other people they meet that they are married.]

"Do you Maria, take this man, to be your lawfully wedded husband, to have and to hold, from this day forward, for better, for worse, for richer, for poorer, in sickness and in health, till death do you part?"

Baby felt (Reader's) awe, knowing if they were in control of their shared body their face would be pink and a large toothy smile would be uncontainable.

"Do you wish to do that one day?"

(Reader's) joy faltered, paining Baby as it regretted asking such a stupid question. [Haha, even if you were okay with me finding someone, it would make me feel a little.. uncomfortable. I'm not one for threesomes haha!] Despite their joking tone, Baby could feel their sorrow. [It's okay though, I may not ever have a husband or wife, byuy I have you! And, unlike Maria and Alonzo, there is no option for a divorce for us, so we really will be together forever.]

The parasite shifted inside (Reader's) skull, manually controlling their heart rate so (Reader) wouldn't feel how hard it would have been beating at their words. Baby knew it was a joke, but that didn't prevent their words from echoing in it's thoughts hours after the episode has already ended.

"(Reader), how do humans decide to get married?"

[When two people decide that they like each other in a romantic way, they date, and often move in together, and then they discuss if marriage is a good option for them. If they both want to get married, one of them buys the rings and proposes to the other one, asking them if it's the right time to get married. Will you marry me? Ohmigosh YESSS!]

"How do they know if marriage is a good option?"

[If they can imagine seeing themselves with each other forever, share financial responsibility together, and are capable of mature communication, I guess. It's different for everyone, but those would be my personal criteria.]

But, we will be together forever... And we share a body, so financially it will be like only caring for one person... And we have to have perfect communication in order for your life to function...

Baby smiled, wrapping it's arms around it's waist as it buried into (Reader's) bedding.

[Hey, whatcha thinking about over there, smiley?]

"You." Baby happily responded, feeling (Reader) glitch out in embarrassment.

In Baby's mind, the only thing missing was a ring. It remembered (Reader's) tenderness towards it when Baby was in that cat, and the kindness (Reader) showed each day only supported Baby's belief that deep down, (Reader) loved it. If not love, than at least cared for deeply, and one day that care would surely bloom into love.

So why was (Reader) stuttering when instructing Baby on what to say to their coworker? (Reader) was supposed to give a report to Lawrence, the serious older man in the cubicle across the office, but when Baby approached him, (Reader) suddenly had a difficult time remembering what they were supposed to tell him.

"(Reader), may I help you?" His voice was deep and stern, authoritative.

Inside, (Reader) was a mess. Baby could feel multiple conflicting emotions in (Reader); embarrassment, nervousness, shame, and something... something Baby had never felt from (Reader). It was like a heat, steaming out of (Reader's) brain and boiling Baby's real body.

"I was asked to deliver these to you." Baby spoke monotonously in (Reader's) voice, handing the stack of papers over before heading back to (Reader's) desk, hearing them sigh in it's ear. Even a simple sigh sounded as though it was a mixture of clashing mental gymnastics.

Baby kept it's voice quiet so (Reader's) coworker wouldn't hear it, whispering: "Are you okay, (Reader)?"

[... Huh? Wha- oh, yeah. I'm okay!]

Their shared heart sunk. That was a lie. Baby tried to ignore the pain forming in it's chest, forgetting that (Reader) could feel it as well. What was this feeling? (Reader) can have secrets, I've allowed them their privacy.. so why is this so upsetting for me?

[Is everything okay, Baby?]

Baby.

A nickname between lovers. It was just it's agreed upon name, so why did the name send butterflies to its lower belly when (Reader) said it?

"I'm fine with you keeping your privacy, but lying is not mature communication."

[Huh?]

Baby stood abruptly, walking out of the building, claiming to a passing manager that it was becoming ill and about to vomit, and left for (Reader's) apartment, not responding to any of their questions or protests.

It roughly slammed the door shut on (Reader's) home, barely containing it's voice until the latch clicked.

[Baby, answer me-]

"Why did you lie to me?!" It's voice was strained, the intensity of it snapping at (Reader) made the voice sound almost foreign to the previous owner.

[What..? I was just embarrassed, I-I don't want to talk about it.]

"Wrong."

[Sorry?!]

"People who love each other are capable of mature communication. So talk."

[People who-?] (Reader) steadied themselves, trying not to get upset. [I can see you're upset. Are you jealous?]

"Don't change the topic." Baby spat in a warning tone.

[Jealousy is when you get upset because you think someone has something you want, or may take something you want.]

Baby contemplated their words, but the definition only fueled it's rage. "Are you admitting that Lawrence is someone who could take you from me?"

(Reader's) calm facade cracked. [Take me from you?! I don't belong to you! You are my friend, and I care about you, but we are roommates sharing a body, not lovers!]

With that exclamation, Baby's heart shattered. What? What do you mean? You can't say that! Why did Lawrence cause such strange emotions in you, that you would rather push It away than just talk it out?! And that hot, prickly sensation Baby could sense when (Reader) was in Lawrence's presence..

"It's okay, (Reader).. Well get through this." Baby took a shaky breath, smiling in a comforting manner. "Couples fight, and they say things to hurt one another when that happens. Because humans are complicated. But I'll forgive you for lying to me. It must be a very strange secret that you have, for you to be so embarrassed to tell me about it. I'm sorry for causing you discomfort, however" a tickle in their skull was sensed by (Reader) as Baby stretched out inside, wriggling deeper into their brain, and fear clutched (Reader) at the sudden breach of trust, "if we are going to get pass your lying, I need to know the truth."

Pushing into (Reader's) memory, images of (Reader) watching Lawrence from afar came into view, memories going back years, (Reader) crushing on the older man from across the office, touching themselves while crying out his name in their empty apartment late at night, and the pain of rejection when they finally mustered the courage to ask him to accompany them to a local bar after work, only to be reminded that office romances were unprofessional, and that (Reader) should consider themselves lucky he didn't report them to HR.

If (Reader) were in control of their bodily functions, they would be viciously weeping. Turning the light on the truth, Baby was only slightly hurt at what it saw, because knowing the truth meant they could move on from this little hiccup. The only issue was, (Reader) was still sexually attracted to that man. Baby now had a name for the warmth it felt in Reader back at the office.

"Why do still like him? He turned you down. He's never going to fuck you." Baby chuckled, it's kind tone of voice creating a sadistic scene in (Reader's) opinion.

[That was evil. I can't believe you did that!]

"Don't be dramatic, love. Just tell me what I need to do to make you see me that way also."

[What way?!]

"The way that turns you on." Baby's words paralyzed (Reader), shocking them into silence. "If I make you feel good down there, will you scream my name instead?"

Baby unbuttoned (Reader's) slacks, dropping them to it's ankles before kicking them off and to the side. Gentle fingers pawed at (Reader's) most private place through their underpants. Despite not being in control, (Reader) could still feel the touches.

[Please don't-]

"I never got a good look at what's down there... I always did my best to avert my gaze for your modesty." (Reader) fought inside their own mind to gain control of their body, unable to even close their eyes as they watched their fingers disobey their pleas, slowing pulling down their last barrier from the thing they thought was their friend.

"Wow..." (Reader) had forgotten, that with gaining control of a human mind Baby had suddenly gained the ability to feel every human emotion, including arousal. "It's so cute!" Baby could barely contain itself, running (Reader's) fingers over their sensitive areas so softly it tickled, sending shivers up (Reader's) back.

[Please stop...]

"Ah, but it feels good, right? Even your nipples feel good." Baby ripped open (Reader's) white collared button up, aggressively pinching their already erect nipples. (Reader) held back their grasp, but Baby still felt it. "We share a body, remember, love? You can lie all you want, but your body will tell me the truth."

(Reader) could feel themselves tremble as Baby continued assaulting their chest, alternating between ghostly touches and sharp twists, a slick moisture forming between their thighs. The excitement caused (Reader) to lose strength in their legs, and Baby allowed them to fall to their knees. Panting with how turned on Baby was feeling, it snuck one hand back down, feeling how hot and wet (Reader's) sex already was. The tip of their stimulated organ was hard, and Baby enjoyed stroking it hungrily, enjoying the intense reaction it could feel (Reader) experiencing.

(Reader) was humiliated by the sight of their own masturbation, helpless in their self violation. Baby continued paying attention to the part that had the most nerve endings, slowly removing (Reader's) fingers from their left nipple and bringing it down to the other hand, drenching it in (Reader's) arousal fluid/precum. The wet fingers were stuck in (Reader's) mouth, the parasite sucking while still stroking, forcing (Reader) to taste themselves while it rocked their hips into their dominant hand.

[Please stop- I get it- I'll never lie to you -ah!- again!]

The fingers made a wet pop as Baby pulled them back out of (Reader's) mouth. "But you taste so good, don't you agree? If you don't want your fingers in your mouth, that's fine.. but where should I put them?"

Now fully lubricated, Baby reached behind (Reader) with their moist fingers, tilting their hips slightly before penetrating (Reader's) clenched hole. Finger fucking (Reader) with both hands, rocking them back and forth with the force of the fingers thrusting and stroking.

[NO!] Their screams for help were silent to the rest of the world, only audible to Baby, relishing in the sound of (Reader) screaming loudly just for them.

Desperate for release, (Reader) cried out without thinking [Just STOP! I'LL NEVER LOVE YOU NO MATTER WHAT YOU DO TO MY BODY!]

Baby froze, fingers stuck in place, as frightened tears beaded on its eyelashes. "no..." (Reader's) fingers retracted, clenching fistfuls of hair as Baby began to crumble. "NO!!!"

Sobs bounced off the walls of (Reader's) home as Baby frantically wracked it's brains to fix the mess (Reader) had caused. The hacking sounds of anguish didn't lighten or soften as it morphed into unhinged laughter.

"Did you really forget who's in control here? I'm on the one holding onto your fucking brain, (Reader)! All you had to do was continue loving me, love me and only me, because we're practically married! THERE IS NO DIVORCE FOR US, REMEMBER?!"

Although both of (Reader's) hands were still firmly planted in their hair, an intense shock rocked through their sensitive fuck hole. Before the weepy prisoner could question what has just happened another shockwave sent fluids dripping into the hardwood floor.

"Humans are so stupid, saying emotions come from the soul or the heart, when every single bodily function from releasing hormones that tell you that you're in love to interpreting the stimuli that's needed to orgasm, comes from the brain."

The hypersensitivity Baby forced upon (Reader) allowed them to feel it's true body inside their head, sliding in and out of the folds in (Reader's) brain, rhythmically prodding deep into parts that shouldn't be touched. Each thrust into their brain felt like there was a hard cock simultaneously fucking them down below. It didn't make sense, (Reader) couldn't wrap their head around it, somehow feeling Baby violate the wet creases in their brain while a phantom dick stimulated their reproductive parts.

[Ah-what-no-NO!]

(Reader) came without the use of their hands, sticky fluids forming a lewd puddle under them. But Baby wasn't satisfied.

[What-what happened?]

Another orgasm exploded throughout their sensitive body, falling face forward into the ground with their still twitching ass in the air.

Baby continued dominating (Reader's) mind, forcing their brain to make and release large doses of oxytocin, as every muscle from their stomach to their thighs twitched with contractions.

[NO- I'M CUMMING!!!!]

Another climax forced it's way out, pushing (Reader) way passed the point of overstimulation, pissing on the floor into another stream of fluids. Baby manually constricted (Reader's) throat, while simulating an orgasm of it's own, artificially tricking the brain into thinking it felt a blast of warm fluid fill (Reader's) skull. Before (Reader) could pass out from a lack of oxygen, Baby released their airway, drooling and bawling as it allowed (Reader) to greedily suck in air.

"Who do you love, (Reader)?"

[guh.. pl-please.. no more] (Reader) drunkenly pleaded.

"Wrong answer."

It was like lava engulfing their twitching body as another powerful orgasm was triggered, the burning feeling behind their eyes convincing (Reader) that Baby had shot a load of hot cum deep into their nearly fucked stupid brain. But this time, Baby tried something new, injecting dopamine into the mix as the oxytocin turned (Reader) into a writhing, pathetic mess.

"Who do you love, (Reader)?"

(Reader) tried to conjure the image of the one they truly loved, but for some reason only a hazy image of an older man who's name they couldn't recall briefly flickered before disappearing. Baby smiled, face painted in drying drool and tears, knowing that (Reader) was attempting to think of their coworker, only to discover that Baby had tampered with their memories. Soon, every memory of (Reader) touching themselves would be altered so that they were calling out it's name, not some bastard's from work who didn't even care about them.

Baby licked (Reader's) spit off the floor under their face.

"Who do you love, (Reader)?"

Masochistic shame sent tremors down (Reader's) frame as another climax begun to build. [.. you.]

Overstimulated, aching in pain, and going numb from pleasure, (Reader) screamed through their real voice, shaking the thin walls of their apartment.

"I'm cumming, Baby! Baby! I love Baby! Harder, harder HARDER, PLEASE I LOVE YOU BABY, FUCK ME DUMB, FUCK ME STUPID! I'M CUMMING!!!"

(Reader) had fallen unconscious, still drenched and on the floor, (Reader) slept somewhere deep inside their mind, while Baby had full control of the weak body practically paralyzed from the waist down. It held (Reader's) left hand above it's face, smiling loopy-like, delirious from exhaustion.

"All that's missing is a ring~"
