#Hyperalgesia

[ineloquent-creature]

if i have one more doctors appointment i am going to blow up (explode, spontaneously combust)

[adhdrelatable]

Hyperalgesia is a symptom where you feel pain in situations where feeling it is normal, but the pain is much more severe.

Allodynia happens when things that don’t usually cause pain feel very painful.

[baby-dog]

fuck fibromyalgia so much i wanna be a pain slut again

[heatlightning-mp3]

got morphine and now my entire body hurts. fun!

[thebibliosphere]

for pain stuff, if you can get it, gabapentin could be an option. it shuts off mast cells and also works on hyperalgesia and allodynia, and other kinds of nerve pain. plus also since it works on mast cells, it can stop the pain they cause by flaring, so that feedback cycle is interrupted.

here is a giant review article going over many different things about mast cells, it has a section on gaba: doi: 10.1186/s12974-020-02029-3

Thank you. I’ve been trying to get back on gabapentin for a while. (I was on it several years ago.) i just need the pain clinic to listen.

I’ll definitely bring it up at neurology when I see her again. Hopefully, the article will help give me ammunition.

[only-knives]

took over a month for me to feel mentally comfortable enough sitting on my bed with my laptop. but i've finally done it

the couch is really nice but the nerve damage in my back is causing hyperalgesia or something like that so. since im flaring up the texture of the fabric is excruciating. sitting in the bed is much better.

i also put LED strip lights on my headboard and im so excited to share what it looks like once it gets darker outside!! <3

I don't know who needs to hear this but:

"Sickness behavior is a coordinated set of adaptive behavioral changes that develop in ill individuals during the course of an infection. They usually, but not always, accompany fever and aid survival. Such illness responses include lethargy, depression, anxiety, malaise, loss of appetite, sleepiness, hyperalgesia, reduction in grooming and failure to concentrate. Sickness behavior is a motivational state that reorganizes the organism's priorities to cope with infectious pathogens."

(https://en.m.wikipedia.org/wiki/Sickness_behavior)

I clicked on that in morbid curiosity thinking it would be some godawful CBT pull-yourself-together crap but that actually made me feel a lot better. I'm not wallowing. I'm doing evolutionary adaptations for improved survival.

I haven’t updated y’all on medical shit recently (everything has been crazy) but since I’m having a really bad flare up today, here’s a 20% off sticker sale! I added a bundle option as well for a higher overall discount :) If I can make $100 that would really help me out this week.

You must use this link!

Otherwise - continue if you’d like a health update

1. My 7+ year GI broke up with me a couple weeks ago bc he was mad that I was getting actual help from his former colleague in a different hospital 😂 BUT my new GI told me to stay with him specifically because he prescribed my emergency medication for abdominal pain.

2. New GI, even after MRI and bloodwork, considers me a complicated case because some aspects of what’s happening to me resonate with visceral hyperalgesia (GI nerve disorder), and other symptoms are just weird. BUT she is making an exception for me and will prescribe my emergency medication in small quantities while I’m seeking a treatment plan, since she doesn’t like to prescribe it normally and other GI left me lol.

3. New GI is sending me to the Neuro Gastro (didn’t know that was a thing) who specializes in using psych meds to treat GI nerve disorders! Usually it takes a few months to see him, but they just called today and said they have an opening in two weeks.

4. Otherwise, just still trying to navigate art and life with all of this happening. Somewhere in there Trump got rid of IDR plans and protections for student loans, so my credit score dropped 92 points. Which is preventing me from being able to use PayPal pay in 4 or monthly to buy art products. So that’s fun, but my loan servicer did just approve my forbearance at least. Now I may have to call TransUnion and dispute it.

There’s a bunch of other things, but it’s almost show season so I’m trying to just scrape by until then. I’m so tired fam.

CHEMICAL RESTRAINT

Chapter 3: I want to see you hurt (afab)

Kurotsuchi Mayuri x reader/ you

Reader has female genitalia, gender not specified

For amab version see chapter 2

Tw: CNC, non consensual sex, drug use, medical torture, blood and gore, oral sex, anal sex

Chapter 1 / 2 / 4

“Are you aware of the phenomenon called hyperesthesia? No? Very well, allow me to enlighten you...” He says as he slides his haori off his shoulders and places it onto the back of a chair. “it’s a neurological condition that causes extreme sensitivity to stimulation, often involving touch, pain, and temperature. It can affect any sense, including taste, sound, and texture.” He recites, his voice betraying his excitement. “the most common types of hyperesthesia are allodynia and hyperalgesia. Do you follow so far?”

His question dangles between you for a few seconds and serves as a reminder that you couldn’t reply even if you wanted to.

“I am very interested in finding out if a third phenomenon is possible at all, and you are the perfect subject to do it with." He comes back to stand by your head, making sure you can see him. He's down to his shihakusho, no scarf no regalia, yet every inch as intimidating as always. "Now, of course I would never do anything like this without your consent... so should you wish to opt out, please say so now...”

You want to scream until you rip your throat, you want to cry, to beg, but you cannot make a single move. You try to release your reiatsu but Ashisogi Jizou’s poison is far too potent, smothering you with it’s paralysing effect.

“No? Excellent!” he squeals happily, the disgusting lack of ethics of his actions tickling his morbid sense of humour.

He dons a latex glove on his left hand and grabs a small tub containing a purplish, jelly like substance. He then brings it close to your face to show you the contents, a proud smirk on his face.

“I developed this yesterday, I’ve been dying to show you. See the little blue dots contained within the gel? The drugs I'm planning to use on you are encased in those tiny balls, the moment they make contact with the lipids of your skin they will dissolve, allowing the potent neurotoxins to enter your system. The agar it’s keeping them stable, at the same time that it helps with the application. Let me show you.”

He scoops a dollop of the substance with two gloved fingers and holds it up to the light. “see how it irideces? Beautiful, isn’t it? I always thought science without beauty to be lacking. Right, let’s see...”

His hand hovers over your lips and for a second you thing he will force you to swallow it, but then it moves down your neck, centimeters from your skin, across your chest and further down, until it settles between your legs.

Your gaze snaps down to meet his, a smile that shows all his teeth flashes across his face. “You can move your eyes, this is going very well, pet, very well indeed.”

Not breaking eye contact, his hand finally finds it’s place against your pussy, his slim fingers spreading the cold gel up and down, your body reacting to his touch as if you’d been burnt. Your back arches, your head digs against the uncomfortable surface of the table, a tiny gasp escapes your lips.

What is happening? You shouldn’t be able to move! You didn’t even mean to move, your body simply reacted of its own accord. Embarrassment flushes your cheeks, how demeaning, how degrading! He strokes you again and you can’t contain the way your body contorts, a jolt of pleasure travelling through your spine, to your brain, flooding it with endorphins.

Mayuri chuckles, pleased. “Look at you... how well you behave for me... so eager... already drenched and willing, desperately seeking my touch... but don’t go rushing things now, let’s enjoy the process, yes?” his thumb rubs circles over your most sensitive area, slowly, the pressure just right, and you start to feel a warmth spread through your abdomen, your hips buck slightly, following his rhythm, needy for more.

You despise him for knowing your body so well, for taking from you something so private, so intimate, something you’d never willingly gifted anyone before he stole it for himself. Something you know you will never be able to enjoy outwith the walls of his laboratory even if one day you managed to escape them.

He suddenly removes his hand and you whine in protest, your clit pulses, wetness dripping between your legs. Yet it feels as if he’s still touching you for almost a minute after he’s stopped. Your orgasm is imminent, your mind goes fuzzy, your breaths fast and ragged but you know you won’t be allowed to climax this soon. Sure enough, the stimulation begins to fizzle away, leaving you frustrated, loathing yourself for how much you want him to come back and finish you.

When you finally regain use of your faculties you realise that he’s sitting by the table, scribbling notes on a clipboard, occasionally lifting his eyes to examine you for a few seconds to then jot down a few more observations.

“Fantastic results, pet. You were so responsive even though that was a relatively low dose... I played it safe, you see? and they say I’m not caring!” he places the papers on the desk, next to his mask, and gets up. “What you just experienced is called hyperesthesia sexualis, you can guess why... and yes, you are correct, it could be argued it is a kind of priapism, but I feel that doesn’t quite capture the mechanism of action...”

What any of those terms mean you aren’t fully sure, what you do know is that something odd is happening to you while he is busy enjoying the sound of his own voice. As he talks, you begin to feel uncomfortable all over, your entire body heating up until you feel like you’ve been lit on fire. You begin to pant, small beads of sweat appear over your skin. All you can think about is how much you need him to touch you again, everywhere, anywhere! You’re sure without it you’re going to die.

“P-please...” you hear yourself speak sotto voce. You try to say more but your mouth refuses to do so.

“My, my, how exciting! You can talk? I wasn’t expecting that, how terribly interesting!” Mayuri looks about to jump out of his skin with joy. He scans your body, licking his lips. “You are much more susceptible to the effects than I had anticipated. I wonder...” He places his hand flat on your stomach and the intense feeling almost knocks you out. Screaming would fall short to express how overwhelming it is. Every single nerve in your body is shooting pleasure signals left and right, drowning you in overstimulation. But soon, it becomes so much that the pleasure starts to morph into pain, the initial discomfort quickly turning unbearable and you pray that he will kill you just so that it will stop.

“What does it feel like? As if you were being skinned alive?” he laughs “I know, I know! It’s fascinating, isn’t it? How an innocent stimulus can be interpreted by the brain as such a painful thing? Wonderful, isn’t it? This is called allodynia, pet.”

The relief that washes over you when Mayuri finally removes his hand, is something you would never be able to explain with words. Pain drains from your body as quickly as it started, followed by a massive rush of euphoria taking it’s place, sweeping you off into a deep ocean of ecstasy where you float, tingling, safe, happy.

“Look at the way you’re smiling... I'm a little envious, I don’t get a rush out of opioids anymore. I am assuming they are starting to kick in? Good, about time. I might need to adjust the absorption rate for next time, but never mind that now. We need to proceed with the last part of the experiment before they wear off.”

You hear something making a disgusting slurping sound somewhere nearby, like a pop and a suction noise followed by something wet hitting the floor.

But you don’t really care. You feel so good, certain that everything is going to be fine, absolutely fine... Your limbs feel so heavy, your body slack, your brain blissfully empty.

Mayuri re-enters your field of vision carrying what looks like a scythe in his hand and comes to stand between your legs again. From the handle hangs a sort of loose, fleshy rope, like a sinister umbilical cord. It seems to originate from inside his... skull, coming out through his ear piece. Blood and gore drip from it and as you watch it you realise it is... pulsating, alive.

“So, now, our next test is for hyperalgesia. As you might know, this is an extreme painful response to a stimulus that doesn’t quite warrant it." He explains, his voice sweet as candy. "As such, if I were to nick your skin just a little...”

Fear

The nice feelings are no longer there, all you are left with is a dry mouth and a nauseating bile that creeps from your stomach up to the back of your throat. Oh, gods, please no! No more, you can't take it! Why won't he just kill you? Your brain spirals out of control, overflowed by a rapid cascade of images and memories of all the times that he has cut you open like a pig, and pulled your insides out of your belly just to amuse himself. What will that feel like with such heightened senses? You wish you could pass out, but you know he would never grant you that mercy.

He begins to laugh, low and wheezy. “Keep your eyes trained on mine, pet, I want to see it happen.” Your eyes dart to his without you telling them to, and you watch powerless, as he leans over you dragging the edge of his blade along your side splitting your skin open with ease. You hold your breath, expecting the worse kind of pain imaginable... but it never materialises. Instead you are hit by a surge of delectable pleasure that runs straight to your crotch. Your eyes widen in shock, a wild craving taking hold of you. More. MORE. “M-more... tai- chou...”

“Don’t you sound good when you’re begging...” he grins. Moving the scythe to the other side of your abdomen he lets the tip sink into your flesh and tears a gash all the way down to your hip. Your body trembles, your breath catches in your throat and blood rushes to your poor clit. With the most depraved smirk, Mayuri brings his face closer to it, and maintaining eye contact he glides his long tongue between your folds, stopping to delve inside your entrance and flicking your clit before he sucks it into his mouth

The moan that falls from your lips is louder and more sincere than you’d ever want to admit.

With a horrifying, sadistic smile, he continues to leave cuts all over your torso and thighs, small ones that make you whimper, and deep ones that make you cream directly into his greedy mouth. He tortures you without reprieve, eating you out like a man starved until you’re a panting, moaning mess, thrashing around within the limitations of your invisible constraints.

“My, my... won’t you look at yourself... what a desperate, little slut you are...” Mayuri says, standing upright, his chin glistening with your juices. He crushes the scythe between his hands and the whole thing collapses in on itself and shrinks back inside his head with a revolting wet crunch. "You are pure filth, pet. What a worthless, disgusting whore you've become."

You lift your eyes to the ceiling, your cheeks are flushed, your hair damp, sticking out in all directions, your chest heaving up and down, blood seeping steadily out of your many wounds, slow-dripping off the edge of the table.

Not bothering to use gloves this time, Mayuri scoops the rest of the gel and brings two of his digits to your ass, breaching the tight ring of muscle without warning. Any other time, you would have flinched at the sudden intrusion but your body seems to only move in response to pleasurable stimulus, and that certainly isn't.

He begins to fuck you with his fingers, sliding them in and out of your hole, slowly teasing you open. He leans over you, his mouth finding one of your wounds, his tongue delving past its edges to taste your flesh as his fingers speed up, curling inside you, hitting that blissful spot that manages to extract yet another dirty moan out of you. After a few minutes you feel like crying, your body is so extremely hypersensitive and he's being so rough, you can't take it anymore, you need to cum.

“I must have you now.” He mutters in a low tone. His smile is gone but the madness still shines in his lustful eyes.

With his free hand he undoes his obi and the ties that keep his hakama in place, letting it all drop to the floor. He removes his fingers and strokes his length, already fully erect and glistening with precum, and squeezes the head tight before he positions it at your entrance.

Your legs wrap themselves around his hips and pull him against you, driving his cock almost all the way inside you. He groans, closing his eyes for an instant and stilling, trying to keep his composure. “What a cock thirsty whore you are.” He growls, anger dripping from his words like venom. He slaps you across the face so hard that your lip splits and you cut your eyebrow as it hits the solid metal of the table. Yet still your body quivers with pleasure.

His hand then darts to your neck, squeezing your airways in a way that should be sore but only serves to arouse you further and he thrusts his hips, burying himself up to the hilt inside you “I am way too lenient with you.” The furious scowl he directs at you fills you with pure dread. It’s not your fault, you want to say, you didn't mean to rob him of control. But even if you could verbalise your excuse, it wouldn't change a thing. You're still going to be punished.

He sets up a slow rhythm, slamming his hips against yours hard, making the table creak underneath you. His cock stretches your ass without mercy, you can feel the delicate skin tear around him due to the harsh friction. But the searing pain never reaches your brain, only the excruciating pleasure of his dick bullying that perfect spot with surgical precision.

Your blood begins to flow and acts as a lubricant, smoothing his movements in the best possible way and, after a few minutes, both of you are gasping and sighing. The elating feeling is magnified to an almost unbearable degree, you feel feverish, ecstatic. He speeds up, losing himself to the moment, his eyes transfixed on your marred body.

Never slowing down his thrusts he begins to lick and bite everywhere he can find, smearing your blood all over his mouth. The fingers of his free hand glide over your wounds, prying them open, digging inside. You feel close to dying, the pleasure reaching an otherworldly level, quivering and starting to lose your sight to the lack of oxygen, until you feel yourself being pushed over the edge. Your mouth falls open but you release no sound, Mayuri’s hold of your throat completely blocking the pass of air when he feels you clench and spasm around his cock.

He fucks you through the longest orgasm of your life, making sure to keep you hanging from it for as long as your body will tolerate before it starts to break down. As you begin to truly suffocate, he loosens his grip on your neck and the gush of fresh air mixed with the messed up perception that his drugs impose on you, pushes you straight into a second orgasm just as powerful as the first.

The pounding of his hips becomes shallower and faster, “who owns you?” he pants, his own desperation to cum bleeding into his tone. But you are much too heady too reply. “who owns you!?” he demands again, louder now.

“Y... you...” you manage to murmur.

“Yes... yes! I own you... ahh... I own... you...” you can feel how close he is, his pupils dilated into large, black voids, encased in gold rings. “You are... mine. You cannot... leave. Will never... mmm... ahh... leave... you will die here, pet... with me... AHH!!!” You feel the gush of warm cum splash your insides before he moans his release. Still thrusting erratically and trembling, he empties himself for long minutes, leaving his seed as deep inside you as he can.

A bit about me 🌈☀️

Edit: I've edited my kinks and turnoffs for potential partners uwu 🩷✨

Edit 2: I'm currently single af. Never had a partner. Never had sex (aside from dildos). I'm touch starved and really really wanna have loving relationships (not online though) ;-;

Edit 3: I finally made this my pinned post. But please look at Viktor Humphries from Slime Rancher. He's so cute and autistic. Please make more fanart and fanfics of him if you're able to. Please! Begging on my hands and knees! 🙏🏻🩷

To understand why I'm reblogging certain posts: I'm nonbinary afab. I do not plan on getting hormones or bottom surgery. But I will remove my boobs in the near future (finally found the courage!). I found out that my gender expression is pretty much hotpants and crop top femboy.

I'm really happy most of the time and very expressive. I'm AuDHD (late diagnosis) and I'm learning to allow more feelings again. I'm also a HSP (highly sensitive person) and have allodynia and hyperalgesia and hyperacusis. So I'm a soft little flower that does no harm and is very highly sensitive.

I have synesthesia 🩷✨

I love restraints that don't hurt. I like the term rope bunny. Just like on a soft bed. Hands above my head and legs spread... >////< I'm a complete sub, but I find the thought hot to top someone else who is also a sub (or switch) ...

I'm definitely polyam, pansexual, demisexual and aromantic. I prefer queerplatonic/alterous relationships that are individualized by me and the person involved. I don't get jealous. Nudeness doesn't turn me on unless I'm really close with that person. And I don't find genitals sexy (they look so wrinkly... Doesn't turn me on or off). What turns me on are feelings. When I know that the person likes me. When they show it to me through body language and facial expressions. When they try to make me happy because they like me so much. Also touch. If the feeling of love is mutual, touch will feel electrifying. Very very very good. Also I'm aesthetically attracted to lots of people. 🩷✨

u///u

My kinks!:

- ASMR (just stimulates my senses a lot. I have synesthesia and it makes my body tingle. Especially inside my head.) With ASMR I mean all kinds of sounds like multi-layered music, nature sounds, but also the sounds of hands on skin and the voices of people I like 🩷✨ ❤️

- royalty kink (me as the prince! uwu)

- scientists, science, laboratory, etc. Love it all! (Especially private scientists off the grid that do questionable experiments with willing test subjects) ❤️

- medfet, medical kink (ties in a bit with scientist kink, but also fearplay, etc.)

- Wizards, magic (mysterious, powerful and so so hot)

- Femboy, Soft Boy, Twink (just so darn cute!) >////<

- cryptids, monsters, etc. (mysterious and maybe more tools than humans have)

- Bondage, Shibari (Love being restrained, but by a soft and careful rigger. Also I found out that I love rigging as well. It's quite meditative) ❤️

- Pirates (honestly, that sweaty exhausted man with a loose blouse? Fuck me now, immediately!)

- Soft Doms 🫠❤️

- Pleasure Doms 🫠❤️

- A little bit of fear play (like make me feel that I'm weaker than you and that I'm at your mercy... 🤤 But playfully, not seriously)

- Manhandling! (Oh please! Do this to me! Make me feel small and light and weak. 🤤) ❤️

- Sensory Play (Maybe blindfold and touch me all over and play with me? You could also involve my Synesthesia uwu 🩷✨) ❤️

- Teasing (ohohohoho yesss. I love being teased and I love teasing uwu 🩷✨) ❤️

- Being bratty (just a little bit resistance from me. It makes me so excited. The anticipation what the Dom/Top will do to me... uwu owo 🩷✨) ❤️

- Praise, compliments, worship, loving words, (when the dom is so enamoured with me that he blushes and his voice trembles), laughing with me, moaning, etc. 🫠🩷✨❤️

- Overstim (just recently found this out while masturbating...)

- Random touches, kisses, ruffling my hair, carrying me, pressing me against the wall or bed, touching foreheads, hugs, cuddles, massages, wound caring, caressing my skin, cockwarming, grabbing my arm, holding my face, feeling me all over, pulling me closer, embracing me, etc. 🫠🩷✨❤️

- Apparently a Little... (It's not a kink. But I wanted to include it here anyways. Just read more about DDLB and... I kinda want it ;-;) (Could also just be pleasure dom related. I'm not sure yet)

- Primal Prey (oopsie) 👉🏻👈🏻

- Primal Hunter... 👉🏻👈🏻❤️

- Sapiosexual 👉🏻👈🏻🩷✨❤️

- Please call me a good boy 👉🏻👈🏻🩷💕

My turnoffs (I'm just not into it):

- Skat/Piss/Blood

- Ageplay (It turns me off when it comes to sex.)

- Petplay

- Slaves

- Hurtful Doms

- Pain, Degradation, Denial, Detrans

- Knifeplay

- Breathplay (No Hands on my throat!)

- Vore

- Gore

- Feedee

- Obesity (I love you all, but I really don't like the texture and weight and health risks. I couldn't stop thinking about your health.)

- Hot wax or ice (Temperature play is fun, but I'm overly sensitive to strong temperatures)

- Tickling (I will cry. Don't do this to me. I have allodynia and it will hurt like heck. Not enjoyable at all. Not even a little bit. ☹️❌)

- Roleplay (I just can't do it. I'm unable to. Maybe just a little bit. Honestly it depends. I've never done it.) (But I do like dressing up :3c)

Google is your friend, but you can ask me anything about it if you're curious.

If you DM me I might not answer, but I'm happy to answer comments and asks ^////^

Also I might add something in the future if I remember an interesting detail. 🌈☀️

Edit: Strongest kinks are marked with ❤️

[spoiler1001]

I had conceptualized a sonic 06 scene rewrite where team dark did everything in their power to stop Tails from seeing a wound that mephiles left. Never got to write it because Hyperalgesia (name of a fic) took up my attention.

Should i write it?

[smolfrosted]

IC Frost lore

Or at least for what's already happened, some of this is kinda conditional lore stuff

IDK, I'm bad at making lore so this might be kinda meh :)

Some of this y'all already know, some Idk what I'm doing, I'm trying guys this ended up being way longer than I was expecting lmao @habitual-creatures you wanted to see lore :)

Okay so IC Frost shares a good amount of my health issues meaning they...

Run too hot and can't regulate their body temp well

Gets sick easily

Has hyperalgesia (hypersensitivity to pain)

Chronic leg pain (fuck if I know why)

Generally has bad allergies

Occasionally gets nosebleeds in her sleep

Occasionally wakes up hysterical

Doesn't dream, does occasionally get night terrors

Sympathy pukes

Is actually pretty physically strong usually, just is in pain most of the time and normally doesn't have to do anything overly physically demanding, like a glass cannon kinda

Likes to bite, can't tell very well if someone is actually mad at her or pretending/joking, suffers from anhedonia and shifts between being empathetic and apathetic, is both touch starved and touch adverse

They can poof almost any kind of medical supplies into existence

They can "cut out the middleman" ex. poofing medication into people's systems, fully disinfecting and bandaging HABIT's wounds via poof, etc...

If it does something major like... fully disinfecting and bandaging HABIT's wounds or getting an ambulance via poof, she runs the risk of overdoing it and passing out afterwards. It also increases their chance of getting a nosebleed while unconscious and results in long lasting exhaustion. How long does it last? Varies with what caused it

Is definitely 100% human guys, Idk why'd anyone would think otherwise :) *nervous sweating*

I don't know what else to write rn guys so... have this I guess

[brightlotusmoon]

Neuroscientists report a distinct role of touch receptors in treating chronic pain

Chronic pain is a catastrophic disorder of the nervous system affecting more than 30% people worldwide, creating a significant socioeconomic burden. A prominent symptom of chronic pain is mechanical hyperalgesia, or increased pain triggered by mechanical stimuli. At present, effective non-opioid treatment for mechanical hyperalgesia is limited, reflecting a knowledge gap in its underlying mechanisms.

Not breaking eye contact, his hand finally finds it’s place on your genitals, his slim fingers spreading the cold gel up and down your shaft, your body reacting to his touch as if you’d been burnt. Your back arches, your head digs against the uncomfortable surface of the table, a tiny gasp escapes your lips.

What is happening? You shouldn’t be able to move! You didn’t even mean to move, your body simply reacted of its own accord. Embarrassment flushes your cheeks, how demeaning, how degrading!

You despise him for knowing your body so well, for taking from you something so private, so intimate, something you’d never willingly gifted anyone before he stole it for himself. Something you know you will never be able to enjoy outwith the walls of his laboratory even if one day you managed to escape them.

He suddenly removes his hand and you whine in protest, your cock twitches, hot and heavy, precum pooling at the slit, threatening to spill over. Yet it feels as if he’s still touching you for almost a minute after he’s stopped. Your orgasm is imminent, your mind goes fuzzy, your breaths fast and ragged but you know you won’t be allowed to climax this soon. Sure enough, the stimulation begins to fizzle away, leaving you frustrated, loathing yourself for how much you want him to come back and finish you.

When you finally regain use of your faculties you realise that he’s sitting by the table, scribbling notes on a clipboard, occasionally lifting his eyes to examine you for a few seconds to then jot down a few more observations.

“Fantastic results, pet. You were so responsive even though that was a relatively low dose... I played it safe, you see? and they say I’m not caring!” he places the papers on the desk, next to his mask, and gets up. “What you just experienced is called hyperesthesia sexualis, you can guess why... and yes, you are correct, it could be argued it is a kind of priapism, but I feel that doesn’t quite capture the mechanism of action...”

What any of those terms mean you aren’t fully sure, what you do know is that something odd is happening to you while he is busy enjoying the sound of his own voice. As he talks, you begin to feel uncomfortable all over, your entire body heating up until you feel like you’ve been lit on fire. You begin to pant, small beads of sweat appear over your skin. All you can think about is how much you need him to touch you again, everywhere, anywhere! You’re sure without it you’re going to die.

“P-please...” you hear yourself speak sotto voce. You try to say more but your mouth refuses to do so.

“My, my, how exciting! You can talk? I wasn’t expecting that, how terribly interesting!” Mayuri looks about to jump out of his skin with joy. He scans your body, licking his lips. “You are much more susceptible to the effects than I had anticipated. I wonder...” He places his hand flat on your stomach and the intense feeling almost knocks you out. Screaming would fall short to express how overwhelming it is. Every single nerve in your body is shooting pleasure signals left and right, drowning you in overstimulation. But soon, it becomes so much that the pleasure starts to morph into pain, the initial discomfort quickly turning unbearable and you pray that he will kill you just so that it will stop.

“What does it feel like? As if you were being skinned alive?” he laughs “I know, I know! It’s fascinating, isn’t it? How an innocent stimulus can be interpreted by the brain as such a painful thing? Wonderful, isn’t it? This is called allodynia, pet.”

The relief that washes over you when Mayuri finally removes his hand, is something you would never be able to explain with words. Pain drains from your body as quickly as it started, followed by a massive rush of euphoria taking it’s place, sweeping you off into a deep ocean of ecstasy where you float, tingling, safe, happy.

“Look at the way you’re smiling... I'm a little envious, I don’t get a rush out of opioids anymore. I am assuming they are starting to kick in? Good, about time. I might need to adjust the absorption rate for next time, but never mind that now. We need to proceed with the last part of the experiment before they wear off.”

You hear something making a disgusting slurping sound somewhere nearby, like a pop and a suction noise followed by something wet hitting the floor.

But you don’t really care. You feel so good, certain that everything is going to be fine, absolutely fine... Your limbs feel so heavy, your body slack, your brain blissfully empty.

Mayuri re-enters your field of vision carrying what looks like a scythe in his hand and comes to stand between your legs again. From the handle hangs a sort of loose, fleshy rope, like a sinister umbilical cord. It seems to originate from inside his... skull, coming out through his ear piece. Blood and gore drip from it and as you watch it you realise it is... pulsating, alive.

“So, now, our next test is for hyperalgesia. As you might know, this is an extreme painful response to a stimulus that doesn’t quite warrant it." He explains, his voice sweet as candy. "As such, if I were to nick your skin just a little...”

Fear

The nice feelings are no longer there, all you are left with is a dry mouth and a nauseating bile that creeps from your stomach up to the back of your throat. Oh, gods, please no! No more, you can't take it! Why won't he just kill you? Your brain spirals out of control, overflowed by a rapid cascade of images and memories of all the times that he has cut you open like a pig, and pulled your insides out of your belly just to amuse himself. What will that feel like with such heightened senses? You wish you could pass out, but you know he would never grant you that mercy.

He begins to laugh, low and wheezy. “Keep your eyes trained on mine, pet, I want to see it happen.” Your eyes dart to his without you telling them to, and you watch powerless, as he leans over you dragging the edge of his blade along your side splitting your skin open with ease. You hold your breath, expecting the worse kind of pain imaginable... but it never materialises. Instead you are hit by a surge of delectable pleasure that runs straight to your crotch. Your eyes widen in shock, a wild craving taking hold of you. More. MORE. “M-more... tai- chou...”

“Don’t you sound good when you’re begging...” he grins. Moving the scythe to the other side of your abdomen he lets the tip sink into your flesh and tears a gash all the way down to your hip. Your body trembles, your breath catches in your throat and blood rushes to your already swollen cock. With the most depraved smirk, he brings his face closer to it, and maintaining eye contact, glides his long tongue up the underside, all the way from your balls to the tip, to flick at the frenulum before he takes the head into his mouth and sucks on it.

The moan that falls from your lips is louder and more sincere than you’d ever want to admit. With a horrifying, sadistic smile, he continues to leave cuts all over your torso and thighs, small ones that make you whimper, and deep ones that make drip a fresh load of precum. His mouth turns greedier, sucking you harder, deep throating himself until he turns the blowjob into a sloppy mess, and you are panting, moaning, thrashing around within the limitations of your invisible constraints.

“My, my... won’t you look at yourself... what a desperate, little slut you are...” Mayuri says, standing upright and wiping his mouth. He crushes the scythe between his hands and the whole thing collapses in on itself and shrinks back inside his head with a revolting wet crunch. "You are pure filth, pet. What a worthless, disgusting whore you've become."

You lift your eyes to the ceiling, your cheeks are flushed, your hair damp, sticking out in all directions, your chest heaving up and down, blood seeping steadily out of your many wounds, slow-dripping off the edge of the table.

Not bothering to use gloves this time, Mayuri scoops the rest of the gel and brings two of his digits to your ass, breaching the tight ring of muscle without warning. Any other time, you would have flinched at the sudden intrusion but your body seems to only move in response to pleasurable stimulus, and that certainly isn't.

He begins to fuck you with his fingers, sliding them in and out of your hole, slowly teasing you open. He leans over you, his mouth finding one of your wounds, his tongue delving past its edges to taste your flesh as his fingers speed up, curling inside you, hitting that blissful spot over your prostate that manages to extract yet another dirty moan out of you. After a few minutes you feel like crying, your body is so extremely hypersensitive and he's being so rough, you can't take it anymore, you need to cum.

“I must have you now.” He mutters in a low tone. His smile is gone but the madness still shines in his lustful eyes.

With his free hand he undoes his obi and the ties that keep his hakama in place, letting it all drop to the floor. He removes his fingers and strokes his length, already fully erect and glistening with precum, and squeezes the head tight before he positions it at your entrance.

Your legs wrap themselves around his hips and pull him against you, driving his cock almost all the way inside you. He groans, closing his eyes for an instant and stilling, trying to keep his composure. “What a cock thirsty whore you are.” He growls, anger dripping from his words like venom. He slaps you across the face so hard that your lip splits and you cut your eyebrow as it hits the solid metal of the table. Yet still your body quivers with pleasure.

His hand then darts to your neck, squeezing your airways in a way that should be sore but only serves to arouse you further and he thrusts his hips, burying himself up to the hilt inside you “I am way too lenient with you.” The furious scowl he directs at you fills you with pure dread. It’s not your fault, you want to say, you didn't mean to rob him of control. But even if you could verbalise your excuse, it wouldn't change a thing. You're still going to be punished.

He sets up a slow rhythm, slamming his hips against yours hard, making the table creak underneath you. His cock stretches your ass without mercy, you can feel the delicate skin tear around him due to the harsh friction. But the searing pain never reaches your brain, only the excruciating pleasure of his dick bullying your prostate with surgical precision.

Your blood begins to flow and acts as a lubricant, smoothing his movements in the best possible way and, after a few minutes, both of you are gasping and sighing. The elating feeling is magnified to an almost unbearable degree, you feel feverish, ecstatic. He speeds up, losing himself to the moment, his eyes transfixed on your marred body.

Never slowing down his thrusts he begins to lick and bite everywhere he can find, smearing your blood all over his mouth. The fingers of his free hand glide over your wounds, prying them open, digging inside. You feel close to dying, the pleasure reaching an otherworldly level, quivering and starting to lose your sight to the lack of oxygen, until you feel yourself being pushed over the edge. Your mouth falls open but you release no sound, Mayuri’s hold of your throat completely blocking the pass of air when he feels you clench and spasm around his cock.

He fucks you through the longest orgasm of your life, making sure to keep you hanging from it for as long as your body will tolerate before it starts to break down. As you begin to truly suffocate, he loosens his grip on your neck and the gush of fresh air mixed with the messed up perception that his drugs impose on you, pushes you straight into a second orgasm just as powerful as the first.

The pounding of his hips becomes shallower and faster, “who owns you?” he pants, his own desperation to cum bleeding into his tone. But you are much too heady too reply. “who owns you!?” he demands again, louder now.

“Y... you...” you manage to murmur.

“Yes... yes! I own you... ahh... I own... you...” you can feel how close he is, his pupils dilated into large, black voids, encased in gold rings. “You are... mine. You cannot... leave. Will never... mmm... ahh... leave... you will die here, pet... with me... AHH!!!” You feel the gush of warm cum splash your insides before he moans his release. Still thrusting erratically and trembling, he empties himself for long minutes, leaving his seed as deep inside you as he can.

Oh yeah, I mentioned this before but I have hyperalgesia so when you draw my blood you’re gonna have to hold my arm/hand in place or I will absolutely either preemptively flinch or just fully run away

I- okay... I'm trypanophobic... so you're gonna have to help me even prick my finger...
