It's not love.
Any sane person would understand that the connection between you and Reiji is far from romantic. You're not sure vampires could even feel love. That would make them human. Instead, it was something akin to obsession, an unhealthy adoration. Snared by desire for one another—a desire for companionship and safety on your end, a desire for your entire being on his.
His unfeeling heart was a prison from which you couldn't escape. But, anymore, you weren't sure you wanted to.
You sit on a stool in the lab, quietly admiring the intense concentration that pinches between Reiji's eyebrows. Within one of his beakers, he stirs a shimmering red liquid. So deep it's nearly the color of blood. It's hypnotic, the way it swirls within the glass. Your gaze flits between the two. Reiji hadn't told you what his experiment was for today, only that he required you there so he could use your blood. It was never pleasant to be poked and prodded by a vampire as sadistic as him, but he had done it with minimal remarks. Whatever this poison was, it was more important than torturing his favorite lab rat.
Finally, Reiji took the beaker and poured a small amount into a separate vial. "Drink this."
You tense. "What is it?"
"I didn't ask you to speak. I told you to drink." Reiji approaches your stool, the unknown substance in hand. "Besides, telling you now could unconsciously influence the results. I assure you, though, that it shouldn't kill you."
Shouldn't and wouldn't were two very different words. Uneasy, you shift toward the vampire, crossing your ankles around the stool. You expected something like this to happen when he invited you to stay, but it didn't make you like it. Reiji is notorious for his experiments. You've been dosed with countless drugs and poisons—it's a wonder you're still alive. But you also know Reiji wouldn't kill you like this.
That much you're sure of.
Reiji cups your chin, coaxing your jaw to open. You part your lips, allowing him to press the glass to your mouth, and the mysterious liquid trickles in. The taste is peculiar, metallic, and earthy, likely from your blood and various herbs. It's thick and warm from the Bunsen burner but not the worse thing he's put in your mouth. Reiji guides your head back, ensuring you ingest every last drop. His wine-colored eyes peer at you inquisitively. An invisible smirk lines his mouth at your compliance.
The taste lingers on your tongue. You swallow. What you would give for a glass of water ...
Reiji's hand lingers, thumb tracing your jaw. "Tell me: do you feel anything?"
You go through the usual checklist of maladies. Wiggling fingers and toes, checking for signs of paralysis. Your throat doesn't burn, and you feel no sharp pains shooting through your being or fire burning in your muscles. There are no sharp contractions. No itch to peel the flesh from your bones. Nothing to suggest you might keel over and begin to seize. You can still hear, smell, see, feel, and taste.
However, you are far from relaxed.
"No," you say, relieved you can still speak. "Nothing."
Reiji studies you, expression unreadable.
It could be a slow-burn poison that would take several minutes to kick in. It would not be the first time Reiji used such a drug on you. Or, it didn't work at all. You didn't voice this thought, though. Pointing out one of Reiji's failings would result in a harsh whipping later, and you valued the ability to sit down more than smartassery.
You lay your palms flat on your knees, taking slow, measured breaths. Waiting to feel something stir within you.
If you weren't as close to the vampire as you were, you wouldn't have seen any perceivable difference in his demeanor. Reiji was nothing if not the proper gentleman. But as the minutes tick by in silence, you can see his agitation brewing below the surface. Every second you don't display what Reiji expects, his jaw clenches tighter. He scribbles in his notebook intermittently.
Finally, you gather the courage to ask. "Can you tell me now what it was supposed to do?"
Reiji lifts his pen, peering at you over his glasses. "A recipe for an improved aphrodisiac, as requested by Laito. The intended effects would have resulted in a high body temperature and agitation, as well as sensitivity of the skin and enhanced energy." He flips the page. "The basics of the drug mimic your typical aphrodisiac, but I adjusted the formula to involve a more experimental herb. Naturally, this is my first attempt using such a technique, so I suppose it isn't out of the possibility that it would fail. However, I find it rather odd that you're not experiencing any signs of—"
Abruptly, he stops, head snapping toward you. His nostrils flare. The suddenness of his movement made you jump. Sharply, you inhale as you stifle a shout.
You shrink on the stool. Reiji's unblinking stare is ... unnerving.
"What is it?"
Reiji furrows his brow. "Your scent. It's ..." He advances. But his movement is hesitant, a far cry from his usual self-assuredness. "Strange."
In a flash, Reiji grips your wrist and pulls it to his nose, inhaling deeply. His grip hurts. It grinds against your delicate joints, threatening to crush them. Yelping, you fight your instinct to push back.
"Rei-Reiji!"
"This fragrance ... The scent of your blood is overwhelming. Especially here, where your skin is thinnest. As if it's calling for me." Reiji's lips ghost over your flesh. A whisper of a kiss. His mouth parts and he traces the web of veins with the tip of his tongue. "It's maddening."
"Reiji," you try again, "You're hurting me."
He chuckles. "Hm, is that so? Then let me hurt you more."
Reiji spreads his mouth wide and sinks his fangs into your inner wrist. They slice through the skin like two white hot stakes. You can practically feel them throbbing as he pierces you. You choke on a scream, gripping the edge of his table until your knuckles blanch. The instant your blood touches his tongue, something changes in him. Reiji pulls you closer, splaying his free hand on the small of your back as he hunches over. It's a far cry from his usual composed demeanor. His breathing is ragged—gasping in between gulps as if he were dying of thirst.
He drags his tongue over the garish puncture wounds, kissing his way up your forearm. You shudder. Something's wrong. Sweat beads along Reiji's hairline and his cheeks are flushed. You try to push him back in vain to be a voice of reason in this scenario. But, as soon as your hand touches his bicep, you're struck by how hot he's become. He's practically boiling alive.
"Reiji, please listen to me—! Your drug, I think it's done something to you." It's the most logical explanation. Only after you drank the aphrodisiac did he begin reacting strangely. "You're burning up—where's the antidote?"
He growls at your pathetic attempt to free yourself. "There is no antidote, you fool. It's an aphrodisiac, not a poison. Gnnn—!" Reiji buries his face in the crook of your neck, scraping his teeth against you. "Haa ... Your blood has never been so enticing. The drugs ... they must have amplified your scent. I wouldn't be surprised if the whole damn house could smell you by now. I need more. Give me every last drop; let your master drain you."
Reiji sinks his fangs into your neck, fisting the back of your shirt like you were the only thing anchoring him to the Earth. Heat rushed through you toward the wound. The tips of your fingers tingled as the blood loss set in. You held on tight, embracing him with shaking arms.
If what Reiji said was true, then his experiment must have backfired. Instead of arousing the drinker, it turned their blood into catnip for vampires. And if that were the case, what would stop Reiji's brothers from busting down the door ...
Oh, God, this was not good.
Reiji bit you again, lower. Then a third time. A fourth. A fifth. There was no rhyme or reason—he hardly sucked the new punctures. It seemed that all he wanted was to see you saturated red. Finally, when there was nowhere else for him to mark, Reiji used his leverage against your shirt to rip it in two. Unobstructed, blood dribbled down your collarbone, over your breasts, and below your navel. Reiji chased every drop, lapping, nipping, and sucking every bit of you he could reach.
Suddenly, Reiji grabbed the back of your thighs and hauled you onto the table. His terrible grip hardened on your thighs. You'll undoubtedly be left with a ring of bruises in the shape of his hands later. Your cheeks warmed at the thought, knowing you would be marked so thoroughly by him.
Reiji yanks you forward, leaning over your torso as he licks up your spilled blood. Your head falls back; eyes squeezed shut. It feels so ... so good. As if, for the first time, his careless eyes saw you. Wanted you. Uninhibited by decorum or sadistic propriety. It was a ferocity Reiji seemed to assign to his brutish brothers.
"Mmm ... Haaah ... I wonder what you feel when I suck your blood? It's being transferred into my body, becoming my blood and flesh. So hot it burns my throat ... flowing through my body ... haah ... quenching this horrible thirst. Before, it was delicious, but now? It's positively maddening. Gaa—it's not enough. I need more. Something as simple as sucking your blood will not satisfy me tonight. I have to feel all of you. Ah, damnit."
He slides his hands up your hips and strokes your bare waist before attacking the button on your linen trousers. The last thread of his sanity keeps him from tearing them to shreds, as he did your shirt. Instead, Reiji shoves them down your thighs, letting them fall into a careless heap on the floor. His bestial instincts had taken over.
You gasp. "What if someone comes in?"
"Let them see," he snarls. "Then they'll learn this prey is mine and mine alone."
The changes weren't only in his behavior. His eyes seemingly glowed in the dim light like two ruby beacons. They pierced your soul, hypnotic and pulsating as he drank in the sight of your naked flesh. The lower half of his face was smeared with your blood, and you swear his fangs seemed longer than usual.
You squirm, embers of arousal exploding in your core. You shouldn't want it. Reiji's not himself; his visage would have terrified any sane person. But sanity had kissed you goodbye when you stepped foot in the Sakamaki household.
Cruelly, Reiji chuckled. "Poor little human, trying so desperately to squirm away. Don't you understand there is no point? You can't break free."
"Reiji, please."
"Yes ... Say my name. Beg for your master."
You shiver. "Kiss me."
If Reiji were himself, he wouldn't have accepted your demands. But he surged forward, eager to claim your mouth as he had the rest of you. His mouth was hot. Practically scorching, and you wondered if it was from the drug or an effect of your blood. His tongue invaded your cavern, seducing yours into submission. He curled his hand around your neck, eliminating what little space was left. You wrap your legs around him, silently accepting what would come. His arousal throbbed on your thigh. The simplest touch had him growling.
Frantically, Reiji removed his belt. You came to the assist, unbuttoning his shirt. The fabric was drenched in blood and sweat, no doubt ruined. Reiji would surely be upset about that once he came to his senses, but he only cared about removing as many layers as possible before he snapped.
Reiji rutted against your clothed cunt, bearing his fangs. "Who knew my fangs would have such a perverse effect on you? I can feel your want for me soaking through your underwear. Such a good little servant that your body shows such devotion to its master."
With a flick of the wrist, he tore your underwear away as if it were mere tissue paper. You lurch forward again, crushing your mouth to his. What a devoted servant indeed. You know in your heart that you'll do anything to appease him. But right now, all you need is his cock.
Reiji hooked his finger around the gusset of your panties. You could hear the sound of your slick as he rubbed two knuckles against your weeping slit. His thumb traced the engorged outline of your clit, hissing as your hips stuttered upwards into his touch.
"Have you debased yourself so much that you no longer feel shame? You've made a mess down here, and all because I took your blood. Who knew prey such as yourself would enjoy being devoured ... it doesn't displease me." Reiji spreads his fingers across your pussy lips, displaying your needy hole. "Tch—your stench has invaded this room. Soon the entire house will know what a slave you are to my fangs. Even still ... I cannot help it. I must sample every part of my servant. I must taste..."
Reiji lowered his face to your exposed cunt, and feasted.
You slam a hand over your mouth, stifling a wail that rivaled that of professional pornstars. Reiji ... Reiji was ...!
"Ah!"
He lapped up your desire. Relentlessly thrusting his tongue in your cunt, swallowing as much of the slick as he could before switching targets to your clit. Stars explode before your eyes, and you cannot catch your breath.
Reiji took hold of your legs, lifting your lower half off the table so he could stand at his full height. The angle restricts your breathing more than before, and his iron grip made it nearly impossible to jerk away.
"Ngh ... Haah! Rei-Reiji! Reiji, oh—fuck."
His open palm collides with the fat of your ass in a flash, filling the room with a resounding crack. You bite your palm to prevent any more slip-ups. Even in this crazed state, it seems he expects you to behave like a proper lady. Yet, he doesn't have the strength to reprimand you, as that would mean parting from your cunt.
Perhaps the drug needs time to kick in. Or, perhaps you merely fed off Reiji's lascivious energy. You craved the pain only he could deliver, the feeling of his fangs ripping you open, the stretch of his cock in your depths. He had ruined you for anyone else—human and vampire alike.
As you thrash your head from side to side, you glimpse Reiji's cock. It hangs heavy on his body, bobbing as he eats you. The tip is painfully red, beads of pre dripping from his slit. Your being aches, pussy fluttering at the sight. Fuck, you need it.
"P-Please," you whine. Reiji's gaze meets yours, kneading your thigh between his fingers as he delved his tongue deeper into your channel. "I need—Master! Ah—I need my master inside me ... Haah ... I need to feel you!"
In a flash, Reiji speared you with his cock, tangling his tongue in yours. The taste of your pussy mixed with your blood coats his mouth, though you're too far gone to care. Over and over, he pounded into you. Digging your nails into his back, you shout his name over and over as if it were a prayer, and he, your God. Reiji fucked you like the world would end any moment. The rest of the room melted away, and you were no longer in the mansion, no longer at risk of his brothers. The only thing in your universe was Reiji, just like it should be.
It's not love, you remind yourself. But what is love to a vampire? What is it, if not obsession, pain, and ownership over someone? You were Reiji's through and through: body, mind, blood, and soul. As he wrecked your being, you realize that this is what you were made for. If such a thing existed, it was your fate to be his property. To be ruined by Reiji Sakamaki.
Reiji mars your body with his fangs. Each bite is his brand, your blood, his life. The knot of arousal tightens in your cunt, begging to snap. Tears prick your eyes, and you embrace him harder.
This secret forces you to speak:
"I feel you."
Reiji removes himself from your latest wound, chest heaving. "Ah—What did you say?"
"You asked me—nhh—asked me before what I feel when you drink me." You embrace him harder, arching up. "I feel you. You surround me, entrap me, and I never want it to end. I ... haah ... I want to fill my master. P-Please, suck me more."
Reiji swears in a language you do not understand. He takes your chin and forces you to stare into his eyes.
"Then—let my fangs give you the pleasure you so desperately crave."
A high-pitched ringing sounds in your ears, and you cannot look away. Reiji holds your gaze as he lowers himself to your chest and sinks his fangs into the swell of your breast.
From out of nowhere, an orgasm crashes over you. Your cunt seizes around Reiji, spasming on his length as Reiji digs his fangs deeper and deeper into your body. Your body shakes as wave after wave of pleasure rolls over you, hips jerking, clit tingling. It's like a never-ending orgasm, and you can't stop.
Only when Reiji shuts his eyes and removes his teeth do you finally stop cumming. Your body falls limp under him. Did he just...?
He did.
Only once before had Reiji used hypnosis on you, but it was early in your relationship and not for something like that. The feeling of his claws sunk into your brain, overriding your autonomy, awoke a previously unknown desire within you. You want to feel it again. No, you need it.
"Ahaha—that face. It's not an unpleasant sight." Reiji grins, flashing his blood-stained teeth. "Good servants obey their masters; it's only natural that you would enjoy submitting to me ... Haah ... the feeling of you coming apart over my fangs ... it does something to a vampire such as myself. Perhaps I should—ah—train you to respond in such a way. I can already picture it: your pathetic expression lit with shock as you succumb to my bite, untouched. Nfufu—you are lucky I feel generous right now. Your benevolent master demands to see you do it again."
Your mind is putty in his hands. The ringing returns in your ears as your body braces itself for his bite. Reiji is cruel this time. He bites hard—the sort of bite that would usually blind you with pain, but the signal gets scrambled in your brain, and you cum, hard. It's something beyond euphoria, and your vision goes white.
You are everything and nothing at the same time. Your body is heavy yet weightless. Pain and pleasure intermingle, switching roles, becoming one, and dissolving into meaningless warmth.
You're on the edge of consciousness as Reiji cums as well. Amazingly, the feeling disrupts the blanket of nothingness. It's so hot that you feel you're burning alive from the inside out. And you understand what Reiji means when he drinks your blood. He is now as much a part of you as you are to him.
The last thing you hear is Reiji's voice—a strangled moan, bleeding into a murmur of your name—before being consumed by the abyss.
✞
You come to some time later. It could have been minutes or hours. Time is irrelevant in this place, anyhow. You're sat on Reiji's bed, stark naked and alone. Your body has been cleaned, but you know Reiji wouldn't dare lay you on his sheets if you were still dirty. He wouldn't risk you ruining anything else of his.
"Hm? You're awake."
Shakily, you push yourself upright. Nausea rolls in your stomach; your head swims from blood loss. Reiji sits at his desk. He appears freshly showered, the ends of his hair still damp. He wears another of his button-down shirts, though it's only half done, revealing the pale expanse of his chest.
"It was rather rude of you to keep me waiting for so long. Although, given the circumstances, I suppose I will allow it. It's not often that one of my experiments goes awry, but such is the nature of science. You'll find a glass of water and iron supplements on the bedside table. Take them."
You follow his direction, draining the glass of water in seconds. It's far from ladylike, and you can see the displeasure on Reiji's face, though. Thankfully, he says nothing.
"How are you feeling?" you ask softly.
"I am myself again. You need not worry." Wryly, he smiles. "I shall not pounce on you as you are, even if it is tempting. I have no intention of killing you yet."
This, you know. Still ... "I'm sorry the drug didn't work how you hoped."
"Yes, well ... I do not consider it a complete waste. I'm sure I will find a suitable use for such a drug and save it for further experimentation. I have finished my notes on the ... experiment, and would appreciate you giving me your feedback as well, as an active participant."
If more blood were in your veins, you're sure it would rush to your cheeks. But, as it was, you could only muster a nod and drop your gaze.
"Of course."
"But only when you've been suitably washed. At the moment, your stench is an unwelcome distraction that should be dealt with immediately. I took care of the basics, but as you can see, I have been quite occupied."
"I understand. I'll get to it." As soon as I can feel my legs.
Gingerly, you swing your feet over the side of the bed and gather your bearings. You catch sight of your image in the mirror and flinch. Your skin is mottled with bruises and bites. You look like a chew toy that has been put through the wringer. Although, that might not be an inaccurate description ...
Most of the wounds have been sealed over by Reiji and are in varying stages of healing. You've learned in your time here that a vampire's saliva has healing properties, which are useful for treating ragged bites to prevent further bleeding or death. Unfortunately, it doesn't conceal the bruises their teeth leave behind. As you skim your thumb across a particularly gnarly bruise, a new problem arises.
"Say, Reiji...?"
"What is it?"
"Do you think—that is to say if you don't mind—I can borrow something of yours to cover up with?"
Reiji pushes his glasses further up his nose. "Why should you? It's nothing I haven't seen before, or have you fallen victim to a sudden onset of amnesia?"
"Well, I don't have any clothes, and I would rather not walk through the hallway exposed like this for anyone to see."
He exhales a one-note chuckle. "There will be no need for that."
"But, you told me to clean up...?"
"Which you can do in my en suite." Reiji gestures behind him to his bathroom. "Escaping from me is, regrettably, not in the cards for you this evening, my dear."
"That's not what I..." You shake your head. "I didn't want to assume."
"Is that so." Reiji stands from his desk and makes his way to where you sit. He places two fingers below your chin and tilts it up, maroon eyes glinting sadistically. "Oh my ... it seems one of your injuries has reopened. Allow me."
In one swift motion, Reiji ducks his head to the crook of your neck and licks the bite in question. His tongue drags over your skin methodically, circling the torn edges of the puncture wound in a motion that could only be seductive. You bite your lip, fighting the urge to shiver. It reminds you of how he teased your clit as he ravaged your cunt...
Reiji sighs, skimming his lips over your jaw before settling beside your ear. "Have you forgotten already?"
"I ..."
"Hmm. I seem to recall a certain reaction you had to the use of hypnotic suggestions. How your blood heated ... sweetened, moments after you realized what I had done."
You swallow hard. No. You certainly hadn't forgotten that.
"I'm curious to see how far this interest of yours goes ... How much it will take to break you. Oh? Oh, dear, you're trembling." Reiji pulls back, standing to his full height. "You needn't worry. As I said before, I have no intention of killing you tonight. The bath will come first. I won't act until you have recovered a suitable amount of strength. Only then will I break you."
