“Vox!”
Shoto scrambled into his office carrying a book. It was visibly old but not tattered, leather cover and yellowed pages. Vox could smell that old book smell as soon as he turned in his chair. He looked at Shoto with raised eyebrows. “What is it, my boy?”
Shoto opened up the book to the page he was bookmarking with his finger. He turned it around so the words faced Vox.
“I was doing some reading and I came across this, I’ve never heard of it before. Do you know anything about it?”
Vox took the book from the boy's hands and skimmed over the page. “It’s talking about a bloodlust,” he said after a few moments.
“Yeah, I’ve never even heard of that. What is it?”
“It occurs in a lot of demons, it’s a genetic thing. Once every couple of decades they’ll go through a period of time where they’re.. filled with more malicious intent than usual, we’ll say.” Shoto nodded.
“It’s kinda like an increased prey drive. It comes with heightened senses- and, as the name implies, if they smell blood, they go into this crazy frenzy and do whatever they can to get more of it.” Vox speaks with his hands as he talks, Shoto watching him and listening intently.
“So.. they basically turn into a vampire?”
“Not quite. It’s less, ‘suck your blood for sustenance’ and more ‘tear you apart to satisfy a primal urge’. It’s a really nasty, deadly thing. ..I hate getting it.”
The boy blinks.
“Wait, you- you get these?”
“Yeaahh, my mom has the gene. A true nuisance but ah, can't be helped-“
“Why are you so casual about it!” Shoto looks at him bewildered. “You just said it’s super deadly and it sounds awful, how are you so casual about that??”
Vox looks at him unimpressed. “Relax, my boy. I haven’t had a bloodlust since before you were even a concept. And besides, they don’t last very long anyway- I think mine are only a few days, but the sooner it’s sated the sooner it goes away..
..although,”
“What?”
“That probably means I’m due for one soon.”
————————
Shoto offered to make dinner tonight.
While Vox is usually the cook of the house, Shoto had to admit he just wasn’t looking too hot- a shocker to everyone, really. He was paler than usual, irritable, and had this slightly wild look in his eye. He lacked more coordination than usual, and the slayer doesn’t think putting him in front of a knife or hot stove would be best. Shoto’s a fine cook anyways, so Vox has no problem passing the job to him.
Vox emerged from their shared bedroom and padded into the kitchen. Shoto, cutting vegetables, soon felt a presence to his right and a shimmer of black hair in his peripheral vision. He hummed at Vox in acknowledgement, focused on making these slices even.
“How’s it going?” Vox asked. He sounded soft, but Shoto could feel his body heat from where he was standing. ‘ Is he running a fever?’
“Good,” Shoto said, finally turning to Vox to continue. “I’m prepping these and then I’ll start on the steak.”
Vox’s mouth watered at the idea of a nicely cooked steak. He still had that wild look in his eye, and the idea only made it worse. Though he usually prefers it on the medium side, maybe he could ask Shoto to cook his rare. Blue rare, even-
The demon shook his head to shake the thoughts away. What’s gotten into him? Shoto looked at him with a concerned gaze, slowing the speed he was cutting at to focus on him. “Dude, are you feeling okay? You look a little off.”
“Yeah, I’m fine,” Vox lied. “I think I’m just hungry.” He smiled to reassure the boy. ‘Yeah, just hungry. For a juicy, rare, blood-soaked steak-‘
Oh.
Vox's smile dropped.
Oh.
“Vox?”
“Shoto, I-“
“ Shit! ” Shoto dropped the knife with a haphazard clanging against the cutting board. He was looking at Vox instead of the vegetables he was cutting, and accidentally nicked his finger. The boy held his finger in pain, an obvious red dot forming on the tip of the digit. “I don’t think it’s that deep. Can you hand me a paper towel? ..Vox?”
His vision was tunneling. The demon's eyes were glazed over, transfixed on the sight of Shoto’s finger. The scent coming off it. Subconsciously, Vox licked his teeth underneath his lips, and went to grab the boy's wrist.
“V-Vox?”
“I’ve got it, my boy,” he murmured. He sounded half asleep, lifting Shoto’s finger up to his lips. His mouth watered . “I’ve got it.”
As Vox licked a flat stripe across the wound, it finally clicked in Shoto’s brain that this is the bloodlust he should have been expecting.
Vox groaned, deep and guttural, eyes rolled back in his head at the taste. His grip on Shoto’s wrist got painfully tighter, but before the boy could let out a smidge of protest, the demon's mouth was back on his finger and actively suckling on the wound, desperate to get more of the addicting substance. More of Shoto’s blood.
Shoto squirmed at the slight pain, but also the lewd scene playing before him. The Vox Akuma, Top Extraordinaire, was suckling on his fingers like he was prepping to suck his cock. He whined, a blush crawling to his cheeks and the tips of his ears. Vox pulled back, panting like he had come up out of the ocean for air.
“You taste so sweet, Shoto,” he said. He sounded wrecked, voice gritty and breathless. The wild look in his eye had only gotten worse, and Shoto would be lying if he said, despite the very present fear, it wasn’t making his dick twitch. “I need more of you. Won't you give it to me, hmm?”
Vox was giving him that sickly sweet smile, the one he gave him in bed to lure him into a false sense of security before splitting him open. A very scared voice in Shoto’s head screamed at him that this time, “splitting him open” was not a metaphor. Vox was looking to quite literally devour Shoto whole. The realization hit him like a truck, and a pang of fear went straight down his spine. His eyes went wide as saucers, and he tried to pull away from his boyfriend with little luck.
“V-Vox, hey-“ Shoto began, still attempting to free his wrist with little success. “This, t-this is that bloodlust you told me about, we- w-we gotta snap you out of it-“
The demon pulled him closer by the wrist, their legs slotting together. The heat radiating off Vox was unbearable at this point, and as the boy tried to squirm away again, Vox’s other hand found Shoto’s face, thumb and index finger on either of his cheeks. He left the boy nowhere to look but directly into that predatory gaze, and the sickly smile never left his face as he spoke. “Come now, Shoto. Won't you give me what I need?”
Shoto’s head filled with honey. The demons voice powers trickled into his brain and made it sticky, slowing his thoughts one by one. He whined in protest, but stopped pulling his wrist. Vox grinned at the slight submission. “That’s it, my boy. Sink niiice and deep for me, nice and pliant.”
His eyelids drooped. He left out a soft noise, his voice making his head warm and pleasurably empty. He put his weight on the hand holding his face, much too heavy to hold it up all by himself. With the position of Vox’s leg, there’s no way the demon can miss how Shoto’s dick twitches at the pleasurable buzz. His lewd, subconscious interest in the situation at hand, despite his beating heart giving way to his fear.
“Oh? Are you enjoying this? You like being my little prey, hmm?”
“N-no-!” He starts weakly, a sliver of fight in him still. His words are slurred, fighting but very much losing. “I didn’t, you-“
“You can’t hide your desire from me, boy.” He pulls the slayer impossibly closer. He smells divine , and now, Vox knows the perfect way to get him to give in.
“Be a good boy for me. Give me more of your blood, and I’ll give you exactly what you want, understand?” Vox asked, pressing his leg against Shoto’s half hard cock, sharp nails digging into Shoto’s forearm with the intent to puncture. The boy's eyes fluttered, his resolve unraveling. He gives a small roll of his hips against the friction, chasing the pleasure and eagerly swallowing down the taste of what’s to come. “Y..yes,” he whispered, too weak to speak any louder. “Wan’.. wanna be a, a g-good boy..”
Deep, red crescent moons formed on Shoto’s arm. Vox sighed in satisfaction, lapping up his prize.
“You are. You will be.”
—————
How many times had he been edged? Shoto couldn’t remember. He wasn’t even being controlled by Vox’s voice for the most part, he was just so overcome with pleasure and the need to cum. As he lay with his back arched, face smooshed into tear-stained pillows, all he could do was buck his hips back and beg Vox for more.
The pattern was simple. Vox would find a new, clean patch of skin to sink his teeth into. He would leave a deep, painful bite, maybe a scratch if he wanted to switch it up, suckling the blood out of the wound like a calf. All Shoto had to do was stay still and take it like a good boy, and Vox would finger him through it. Gentle, deep strokes into his aching hole, generously grazing his prostate to keep him sated. When Shoto’s platelids kicked in and closed the wound- faster than normal, thanks to his blessing- Vox would pull out his fingers, coincidentally stopping just short of the boy's orgasm. Rinse and repeat.
And rinse and repeat the demon did, for what felt like hours. Shoto had been able to be obedient for a while, but now his patience was running thin. His body was taught like a livewire, he needed something more and he needed it now.
“Vox,” he whined, wriggling his hips in an attempt to entice him. “More, please..-AH-“
Vox flipped him over with no warning, and the sight of him sent ice down Shoto’s spine. Red splotches spattered across his lips and chin, pupils the size of planets leaving only a thin gold ring to pierce through Shoto’s soul. Shoto caught a glimpse of his teeth, sharp and stained and licked over with an equally soiled tongue. In a way he absolutely shouldn’t be, Vox was the picture of pure sin.
In his haze, Shoto failed to realize what the demon was actually planning until he saw his leg over Vox’s shoulder, his mouth licking from the knee to his inner thigh. “Patience, boy,” he murmured. The full extent of his power was absent in his command, but it still lulled Shoto into lying pliant, even if just for a moment more.
Even as Vox was getting higher and higher on his leg, drawing closer and closer to his innermost thigh, grinning wider and wider as he finally located his femoral artery, where a puncture to it would surely be fatal wait hold on a second-
Shoto’s body worked quicker than his brain, the leg over Vox’s shoulder reeling back before kicking him away. Adrenaline sparked through his nerves, suddenly very desperate to live and keep his blood safely tucked away in his body where it should be. With nowhere to really go, though, Vox was quick to regain a hold of him, hands feeling a little too much like claws digging into his wrists.
Vox was silent for a moment, expression unrecognizable. Shoto was expecting unbridled anger, classic demon rage resulting in a painful death for his disobedient outburst. He tensed in anticipation, grimacing and turning his head away with eyes shut tight and fists closed even tighter-
But all that came was a laugh. Low, at first, but eventually leaving the demon's shoulders shaking with heavy, loud laughter.
“Oh, my sweet, sweet thing,” he cooed, releasing one of Shoto’s wrists to drag an eerily soft thumb over the boy's heart. If they both squinted, they could see Vox’s thumb jump as it lay atop the pulsing skin. Even with his wrist freed, the boy didn’t dare to move it, frozen with fear as he slowly opened his eyes again. His eyes met Vox’s, wet with unshed tears. “What’s wrong, hmm? You’re like a little rabbit, heart beating all too fast.”
His wandering thumb traveled back down to the thigh he was so close to devouring. Shoto tensed once more, squeezing his eyes shut again and turning beet red at the squeak of fear that slips out. Vox’s eyes glimmer, smirk widening. “Ooohh, is this it?” He asked, thumb nail poking directly over the artery. He can smell the sweet blood from under the slayer’s skin, the bloodlust controlling him begging, screaming at him to clamp down on the supple skin and not let go. To make him so weak he can’t move, can’t notice his life being drained away-
“Are you scared I’ll suck you dry? That I’ll kill you, my little rabbit?”
“NnO- pLEASE-“ Shoto blurted out, voice shaking just as much as his body. Trembling like a leaf under Vox’s presence, mouth running a mile a minute to convince the demon to spare him. “Please d-don’t kill me, Vox, I’ll do anything, a-anything please I know this isn’t you, p-please pleasedontkillme-“
Vox had to admit, the boy knows how to put on a good show. The way he squirms, his eyes shut so tight he’s probably seeing stars behind his eyelids, his incessant pleas for the demon to let him live- it gives him a full body shudder, a guttural groan escaping Vox’s lips at the power trip. It shuts Shoto up almost immediately, his eyes fluttering open to cautiously look his predator in the eye.
“Ohh, Shoto, you beg so sweetly for me, you know that?” He coos, nuzzling his nose to the crook of Shoto’s neck as if he was trying to scent him. He can hear Shoto’s panting, heaving in big gulps of air like they’re the last ones he’ll take. After another chuckle, “Dear boy, you’re right. You’re much too cute for me to kill,” and seals his lips to Shoto’s.
A guttural noise of fear escapes Shoto at the contact, but he goes lax just as quickly as the kiss envelops him. Vox is hungry, passionate, all tongue and teeth, but there’s still a sense of him in the way he kisses, and the familiarity sends blood straight to Shoto’s cock. It bobs against Vox’s leg, and the slight friction makes him keen, whining high into Vox’s mouth. The demon swallows every noise with the same fervor as he did to his blood. He pulls back to admire Shoto, and the boy doesn’t even realize Vox bit his tongue until he sees Vox licking up red, a slight pleasurable sting in his mouth.
“V-Vox, I, hngh.. ”
“Tell me what you want, my boy,” the demon persuades, watching another drop of precum trickle out of Shoto’s cock at the use of his voice powers. “You’ve been neglected for so long- I’ll reward you any way you want.”
“P-please,” Shoto gasps, Vox’s voice filling his head again and making it hard to think. All he knows is Vox, all he needs-
“W-want, wan’ you.. need your cock, p-please..”
“Mmm, of course.” And Vox is quick to undo his zipper and belt, tossed out of sight and out of mind. Shoto wasn’t the only one so affected by the scene- Vox was hard and heavy in his own hand, red and leaking. He brings Shoto’s leg over his shoulder again, but the boy makes no move to pull away. Instead he spreads his legs wider, inviting his boyfriend, this demon, this predator , inside him.
And oh, does Vox accept. With a lewd squelch, he strokes himself once, twice, before plunging into Shoto’s hole in one fell swoop.
Shoto screams. It’s too much, it’s too deep, he’s never felt so full in his life- he’s scrambling for purchase on the sheets, trying to catch his breath as Vox starts a cruel pace. He’s being absolutely railed within an inch of his life, each thrust punching the air out of his lungs. With all of the edging from before he’s terribly sensitive, and with the way Vox pistons into him with reckless abandon, there’s no way he’s going to last.
“Mmn, VVox, Vox please- hnn-“
“You’re so- nngh , so tight- you like being my little toy that much?”
Shoto can only let out a broken moan as a reply, frantically nodding his head as words begin to fail him. All he knows his Vox’s cock fucking him so hard, so deep it might as well be in his throat. Vox shifts him in a way that has his cock hitting straight into Shoto’s prostate, and Shoto’s orgasm hits him fast and hard. “VOX-“
Shoto’s vision goes white, ropes of cum splattering across his stomach and chest. He’s a mess of gasps and sobs, so lost in his own head from the pleasure. The adrenaline returns in full force, but different than what he felt before, he’s not scrambling to get away from Vox- no, this is just what he needs. As he fucks him through his high, every nerve ending on fire in the best way possible. Lewd slaps and squelches fill the room, Shoto’s pretty noises almost get drowned out. The fire in his nerves remains as the pleasure turns into overstimulation, and Shoto can feel his mind chip away.
“Mmf, Vvvox please, t-too much- “
“You can take it, Shoto.” Vox grunts, never letting his pace falter even as the boy squeezes his cock with every thrust, as if he was trying to milk him. “Take it like the good- hhhngh, pliant bitch you are.”
Vox is starting to lose the malicious edge to his words, gaze softening only slightly. It’s a shame Shoto doesn’t get to see it, eyes rolled so far back in his head as his mind is broken- piece by piece, thrust by thrust. Gasps and whimpers are all that leave his mouth, far too gone for anything else. Vox wishes he could see himself- infamous demon slayer splayed out on their bed, covered in his own cum, littered in deep bruises, claw marks, and bite marks. Small, red rivulets down his shoulder, splotches of drool and spit mixing with his own sweat making his skin glisten in the evening light.
Perfection .
“Fuck, Shoto-“
Vox cants his hips once, twice more, before slamming as deep as he can, burying himself inside his lover and filling him with his cum. The last thing Shoto remembers is the feeling of painting his stomach white again before his consciousness slips away.
——————————
“Remind me to call Shu later and thank him for these,” Vox says before downing two white, glistening pills, almost radiating in the demon's hand. They’re no larger than typical ibuprofen, but Vox still grimaces as he swallows them down, gripping the arm of the couch he was currently sitting on.
“Are they really that bad?” Shoto asks. He’s sat on Vox’s lap, watching him chase the pills down with water. “What are they, anyway?”
“They’re kinda like a suppressant,” Vox replies. “It’s got holy water and other blessed stuff in it, so it’ll keep the urge to mangle anything at bay, but it also adds a bit of a burn.” He traces a painted fingernail around a bite mark on Shoto’s tummy. With the boy in nothing but those damned short shorts, Vox can’t help but ogle just a little bit. “Though, I doubt I’d get an urge even without the pills- I did a number on you.. I feel a little bad, almost.”
“Don’t be. We’ll just be more cautious next time, yeah?” He reassured Vox, a chaste kiss to the corner of his lips as a cherry on top. The demon smiled, humming in acknowledgement.
“Alright, you,” he began. “Turn around, there’s a bunch of bites on your back I gotta get.” Vox helped Shoto get up and turn so he was facing the TV, letting him rewind the episode of the show he was watching- both to distract from the slight ache, and to keep him from moving or getting bored. Vox grabbed the healing balm from where he’d placed it on the couch next to him.
The pattern was simple. He gathered a small amount from the tin on his finger before smoothing it over a bite mark on Shotos body- this one in particular was on his shoulder blade. He worked it into the worried skin, and as long as Shoto stayed still like a good boy, Vox gave him a kiss on the surrounding skin as a reward and a means of thanks. Rinse and repeat.
And rinse and repeat Vox did.
