the nightmare before christmas.

Summary:

Thanos drinks quickly but carefully. He might be hella pissed, but Nam-gyu’s a human. He’s fragile — not that Thanos would ever say that to his face; Nam-gyu would find a way to kill him all over again. But regardless, he’s gotta pay a crazy amount of attention to how much he’s drinking.

Nam-gyu’s letting out these pitiful little noises, whimpering and shaking as he tries to relax and fulfill his end of the bargain. After all, this is the ‘whatever’ that Thanos wanted. He knew what he was doing when he made a deal with a vampire. It’s hard to feel too bad for him.

And speaking of hard — holy fuck is Thanos dangerously turned on by how pathetic Nam-gyu sounds when he’s getting his blood sucked out.

---

Vampire Thanos and his favorite human have some fun.

Work Text:

A vampire’s supernatural sense of smell comes in handy sometimes. 

When Thanos was just a newly-turned, it was overwhelming. Every single scent hit his nose in the same moment, in every single moment with every single second. For a while, he resorted to just not breathing — he was already dead, for fuck’s sake, so what did it matter?

But eventually he learned to tune the unimportant things out. Developed a filter, almost. Stopped paying attention to every little odor as his brain realized its energy was better spent on the thing that matters:

Blood.

Warm, thrumming blood. The blood of the girls he pays to let him feast on them, the blood of random thieves he catches trying to mug the elderly — blood. The thing that keeps him alive and sated. And he knows how to single out his prey by the smell of it. 

It’s useful now. It means that despite the prevailing scents of spilled liquor, cigarette smoke, cheap perfume, and pungent, unappetizing sweat that clings onto every corner of Club Pentagon, he can smell him. Can pinpoint his location just by the rushing of his blood pressure, just by the faint smell of his expensive cologne and shampoo. 

Nam-gyu’s in the alley smoking a cigarette. He usually is, but while it’s frequently because he just wants to blow off work, this time it’s different. He’s waiting for something. For someone. 

And it’s made even more apparent by the way his breathing hitches when he hears Thanos’s footsteps approach. Thanos can hear his little heart speeding up, and he barely manages to suppress a grin. Nam-gyu’s cute. He really is. 

And his eyebrows furrow all endearingly when he realizes it’s Thanos that’s stepping out from the shadows. Not who he was anticipating, then. Thanos ignores the jealousy the thought triggers in him.

“Nam-gyu, my boy,” Thanos coos as he approaches. “Looking good tonight.”

He really is. His black uniform clings to him like a second skin, accentuating his thin waist, tight core, and thick ass. It makes his pale complexion look almost translucent. Thanos might be throwing stones in glass houses, but the guy looks like he hasn’t been in the sun in years. 

“Yeah?” Nam-gyu snorts when he catches Thanos checking him out unabashedly. He drops the cigarette and kills it with his shoe, then delicately asks, “How good?” 

He already knows the answer. He just wants to hear Thanos say it. And he does. With a sharp grin, Thanos responds, “Good enough to eat.”

He hears Nam-gyu’s heart speed up again, the poor thing running hundreds of miles an hour. While Nam-gyu’s expression is masterfully schooled into casual indifference, his body’s telling a different story. If he listens very carefully, Thanos can even hear him swallow drily at his words.

“When does your shift end?” Thanos murmurs, stepping closer and closer, delighting in the way Nam-gyu’s breathing audibly quickens. The unstoppable fear of a predator approaching. Centuries of evolution to produce an automatic bodily response that Nam-gyu’s trying to ignore. 

“You know when,” Nam-gyu responds simply. It’s true. Thanos has got his entire work schedule memorized. “But,” he starts, “I have plans tonight.”

“Oh, yeah?” Thanos asks, amused. “Any of those ‘plans’ better than letting me stuff you full of drugs and dick?” 

Nam-gyu shivers. “I…” he sputters, momentarily losing his cool. But he quickly regains his composure, repeating, a lot more confidently this time, “Yes. They are, actually.”

That’s… surprising. Thanos hasn’t been surprised in, like, decades. So he’s a little nonplussed for a second, before blankly asking, “What do you have to do?”

Nam-gyu rolls his eyes. The asshole knows he’s got the upper hand right now. “I don’t have to do anything,” he says, seeming irritated by the implication. He pauses for a moment, looks Thanos up and down, and arrogantly states, “I have a date.” 

Thanos’s eyebrows fly to his hairline. “A date, huh?” he laughs. 

“Yeah,” Nam-gyu glares pointedly. “What’s so funny about that, asshole?” 

“Oh, nothing,” Thanos says with an arrogant smirk. He really can’t help himself. “Just that I know you’re not gonna go.”

Nam-gyu’s eyes narrow dangerously. “I’m not?” he echoes through gritted teeth, daring Thanos to say that again.

And, well. Thanos never backs down from a dare. “Nope,” Thanos pops the ‘p,’ further antagonizing Nam-gyu. “You’re gonna show up at my apartment in the middle of the night, instead.” 

Nam-gyu steps up to him, making up for the height difference with his intimidating stance. “Why’s that, huh? You gonna make me?” he taunts. “I don’t care that you’ve got fangs. I can take you down.”

“First off,” Thanos chuckles. “No, you can’t, little human.” Vampires notoriously have supernatural strength. Any attempt Nam-gyu ever makes to ‘take him down’ would be laughable. “Second off, I don’t have to ‘make you’ do anything,” Thanos responds. He leans down a little to be closer to Nam-gyu’s face. “You know why?” 

Nam-gyu’s still staring defiantly up at him, but his heartbeat — his delicious, racing heartbeat — is practically tripping over itself. “Why?”

Thanos’s hand shoots up to grip Nam-gyu’s jaw, turning his head to the side so he can murmur directly into Nam-gyu’s ear. “‘Cause you’re gonna do it all on your own. Because you know no one can fuck you like I do.”

Nam-gyu’s face goes red, pupils dilating. “That— that’s not…”

“‘Not’ what, huh? Not true?” Thanos laughs. “You wanna lie to me right now? I can hear your heartbeat, princess. It speeds up when you lie, and it’s speeding up right now.”

“Don’t call me 'princess,’” Nam-gyu growls. “Fucking weirdo.”

“Oh, you wanna see ‘weird?’ I’ll show you all types of weird, little one,” Thanos says, a bit feral, as he feels his fangs elongate fractionally. “I’ll fuck you on the floor, on the wall, on the ceiling. I’ll fuck you so hard you cry and then bite you so deep you scream. I’ll make you drink your own blood so you can taste how fucking delicious you are, baby. You think I’m weird? You haven’t seen half of it yet.”

“I—” Nam-gyu’s all stammery, eyes wide and skin flushed down to his neck. Cute. Panicked. Prey. “I… I’m not going to your apartment,” he repeats, but he seems a little unsure of himself.

Thanos laughs. “Yeah? You’re not?”

“No… No, I’m… I’m not.”

He does.

Nam-gyu’s shift ended at eleven. It’s a quarter after that Thanos hears a knock on his door.

“I want coke,” is the only thing Nam-gyu says before shoving past Thanos into the threshold. 

“A ‘please’ would be nice,” Thanos comments as he watches Nam-gyu struggle out of his winter coat.

Nam-gyu whirls on him with a deep scowl and threatens, “Thanos, I swear to god, I will strangle you til you’re dead-er than you already are. Don’t play with me. Cut me a line. Now.”

Oh, lord. He’s pissed. “What’s got you in a mood, my boy?” Thanos asks as he sets about doing as Nam-gyu requested, taking out a baggie and his credit card.

It was not a good thing to ask, apparently. “You, asshole!” Nam-gyu seethes, taking the credit card from Thanos’s hand and cutting the line himself. So much for that, then. “Fucking… ruined my night. Got in my fucking head with your freaky vampire stuff. I had shit to do. I ghosted my—” he falters for a moment, then continues, “my date. Instead, what am I doing?” he asks himself bitterly, hands shaking as he thins out the stripe. “Dumb bullshit that I’m gonna regret tomorrow morning.”

“Hey, it’s not my fault that you want this,” Thanos snickers. Nam-gyu’s hot when he’s all mad like this. His eyes get all angry, and his voice is practically a whine. “Do you need something to roll up?”

“Do I look twelve to you?” Nam-gyu shoots back, lowering his head to the counter and covering one of his nostrils as he breathes in the line. Thanos watches him with a little grin, cock twitching in his pants at the way Nam-gyu’s shoulders sag once he’s done. “What else do you have?”

Oh? “What do you want?” Thanos asks curiously. “I have weed, xans, ecstasy, molly, percocet…” He has more drugs hidden in his house than most people have food in their pantries. “I think I still have some pills, too.” 

It catches Nam-gyu’s attention quick. Pill slut. “The ones that I—?”

“Yeah, the ones that you like,” Thanos interrupts, heading to his bedroom. On his nightstand is his cross necklace, and when he opens it, he counts four more pills. He turns around to go back to the kitchen and let Nam-gyu know, but immediately bumps into the boy, who seems to have followed him into the room like a lost puppy. 

Nam-gyu… gets weird about his pills. His eyes go all desperate and pleading, like he’s starving and Thanos is holding his favorite meal. So much so that, without even having to ask, Nam-gyu gets down on his knees, tucks his hair back neatly behind his ears, and sweetly begs, “Can I have one, hyung?”

Jesus… Never in Thanos’s… Well, infinite years, has he heard someone so pretty beg so pathetically. “You don’t play fair,” Thanos chides as he delicately takes out a blue pill and waves it tantalizingly in front of Nam-gyu’s face.

Nam-gyu follows the movement with his entire head, eyes jumping all over the place before he just stops and whines, “Thanos, come on!”

“Funny how quickly your manners fly out the window when I don’t immediately give you what you want,” Thanos notes, amused.

Nam-gyu snarls at him, a little human sound that’s about as threatening as the purr of a cat, and tries to get up. Before he can, though, Thanos splays his fingers on top of his hair and pushes him back down to his knees.

“Stay, princess,” Thanos sings-songs. “I’ve got you. Don’t worry.”

“Don’t call me—” Nam-gyu starts, frustrated, but the argument dies in his throat when Thanos’s fingers approach his face. 

“Tongue out,” Thanos instructs gently. Nam-gyu doesn’t hesitate, just lets his soft, pink tongue loll out of his mouth and waits patiently. “There you go. You can be so good when you wanna be, baby,” Thanos croons as he takes the pill between his index and middle fingers—

And shoves them down Nam-gyu’s throat. 

Nam-gyu’s eyes widen as his throat constricts around the digits, trying to gag. Thanos uses his free hand to cradle Nam-gyu’s jaw, stroking his freckled skin. “Shh, shh. You’ve got this, sweetheart. Just let me play with your pretty throat for a little, yeah?”

Saliva’s dripping down Nam-gyu’s chin now, but the boy nods with a quiet whimper. Thanos hums approvingly at the gesture, then feels around with his fingers. Nam-gyu’s mouth is warm and wet. Under different circumstances, he wouldn’t hesitate to stick his dick in here, instead. But he’s got other plans for tonight. 

He rubs the pill all over the inside of Nam-gyu’s cheek. He can feel the way his mouth is watering like this, how his jaw drops fractionally as he prepares to chew and swallow. His eyes are all glazed over, too. He looks up at Thanos like he’s the only thing keeping him grounded right now.

It’s sweet. So sweet that Thanos finally relinquishes the pill deep into Nam-gyu’s throat and takes out his fingers.

“Swallow,” Thanos orders. Nam-gyu hastily does as told, smiling blissfully. “Good boy.”

“You’re perverted,” Nam-gyu lets him know with an eye roll as he stands up.

“You say that, but I didn’t even ask you to get on your knees.” Thanos snickers at the way Nam-gyu’s face slowly flushes from embarrassment… or anger. It could really be either with this guy. “It’s okay, my boy. Not here to kink-shame you or whatever.”

“Just… shut up and— and—”

Thanos sees the second the coke kicks in. Nam-gyu’s pupils dilate like crazy, and his scowl turns into a wide grin. Nam-gyu cycles through multiple phases when he’s high: aggressive, pliant, bratty, and giggly. It’s always fun to see which one he goes into first. 

“Thanos, hyung,” Nam-gyu says with a wide grin, laughing a little. Giggly, then. He falls forward, gripping Thanos’s shoulder for balance. “You’re so cool. Do you know you’re so cool?”

Oh, wow. “I’ve been told a couple of times.” By you, Thanos wants to add, but he refrains. 

“I think you’re cooler than cool. I think you’re the coolest,” Nam-gyu sighs with this dreamy ass tone. The motherfucker’s gone as hell, so, naturally:

Thanos leans in and asks, “And how much cooler would I be if I gave you another pill, huh?”

He loves how Nam-gyu gets when he takes more than one pill. All excited and energetic and… Well, kind of violent. In a sadomasochistic way, where he’s happy to hurt or be the one getting hurt. As long as someone gets bruised up, he’s there for it. 

And Thanos loves that shit. Loves how fucked up Nam-gyu is, loves that he can keep up with Thanos’s own cruelty. 

“So, so, so cool,” Nam-gyu eagerly says, jumping up onto Thanos’s mattress and sitting on his knees politely. “Gimme, please.”

He’s almost using his manners. “Pick a color, princess.” He’s gonna ask for yellow, Thanos thinks briefly in his head.

And, of course: “Yellow,” Nam-gyu responds, already sticking out his tongue. Fast learner.

It’s got Thanos on a crazy power trip, the way Nam-gyu’s eyelids are drooping and he’s already starting to drool. Yet his expression is so open and trusting, looking at Thanos like he hung the moon.

It’s behavior that has to be rewarded, so Thanos doesn’t mess with him this time; just carefully places the pill in Nam-gyu’s mouth, and—

And his wrist is quickly seized by both of Nam-gyu’s hands, pulled closer. 

He’s forced to stick his fingers down Nam-gyu’s throat, pushing the tablet all the way in as Nam-gyu whines. The motherfucker actually likes this. Lord have mercy ‘cause Thanos sure as hell won’t. Not anymore. 

As soon as Nam-gyu lets his hand go, Thanos pounces, shoving Nam-gyu onto his back with (literal) superhuman force. Nam-gyu shrieks, disoriented, then relaxes with a laugh. 

“You’re such a fucking slut,” Thanos snarls, agitated and so fucking hard from Nam-gyu’s whorish behavior. “You’re batshit crazy, you know that?”

“Watch who you’re calling batshit, bat,” Nam-gyu snickers giddily. Damn. He kinda walked into that one. 

“Shut up,” Thanos grumbles, then locks in. “Get on your hands and knees, come on.” 

Nam-gyu likes doggy almost as much as he likes Thanos himself, so the words immediately have him teeming with excitement. He grins up at Thanos before obediently flipping over, moving down so his ass presses teasingly against Thanos’s crotch. The motherfucker arches his back, that’s how dirty he’s playing. 

“Called me a bat, but now who’s acting like an animal, huh?” Thanos taunts, running a hand all the way down Nam-gyu’s bony spine. “Fucking bitch in heat.”

“Hyung,” Nam-gyu whines. He’s at the bratty phase, then. “Come on.”

“What’s wrong, baby?” Thanos coos, “Getting needy?”

“Been needy,” Nam-gyu huffs, dropping onto his elbows. His shirt rides up at the movement, revealing smooth, pale skin. 

And now Thanos is getting kinda needy, too. Especially because he can hear how Nam-gyu’s desperate little heart speeds up with every single touch Thanos gives him. So he decides to spare both of them and pulls down Nam-gyu’s jeans and boxers in one movement, exposing the human to the cold air of the room. Nam-gyu makes an offended noise, the little brat, then shifts his knees further apart to spread himself open, revealing the swollen pink folds between his thighs. 

Damn. Thanos thanks any god that may exist his dick didn’t stop working when he died, because he needs in that immediately.

He whistles approvingly at the sight, then rubs at his eyes with both hands. “Oh, damn. I think—”

“Don’t say it,” Nam-gyu groans, burying his face in the mattress. 

“—I’ve gyat something in my eye.”

Nam-gyu makes his disappointment audible with a muffled sigh. There’s very few things that can dull Nam-gyu’s mood when he’s high, and Thanos using brainrot lingo is one of them. “You said it,” he complains. Getting more aggressive. “You’re so fucking dumb, Thanos, Jesus fuck—!” His voice raises as he yelps and scrambles forwards to get away. 

Thanos lazily retracts his fangs and focuses on the mark he just made on Nam-gyu’s ass cheek. “Sorry,” he croons unapologetically. “Can’t put cake in front of me and expect me not to take a bite.”

“That hurt!” Nam-gyu whines, flipping over and staring at Thanos with an accusatory glare. “Asshole,” he mumbles when Thanos just laughs at the pout on his face.

“Aw, baby, come on,” Thanos tries to stop laughing, reaching for Nam-gyu’s ankle to drag him back. “I said I’m sorry…”

“Well I don’t accept your weak ass apology!” Nam-gyu scoffs as he kicks Thanos’s hand away. 

Thanos tilts his head, considering the situation. He knows Nam-gyu’s not actually mad, but he’ll definitely keep throwing a fit about it until Thanos: one, apologizes until the sun comes up or two, “I’ll give you an edible if you forgive me.”

“It’s water under the bridge,” Nam-gyu says sunnily, spreading his thighs open to show his agreement. 

“Crazy bitch,” Thanos laughs through his nose. He wants to touch him so bad, but he’s a man of his word, so he dutifully turns to his nightstand and rifles through the drawers until he finds a sealed bag with the gummies. “They’re, like, three-hundred milligrams, I think. Wanna split one?”

The second the words leave his mouth, he realizes two things: the first being how stupid that question was, and the second being who he’s talking to. Nam-gyu does not look impressed. 

He hastily says, “Don’t answer that,” and proceeds to give Nam-gyu a whole edible, then takes one for himself, methodically chewing the tough gummy before swallowing.

Getting high as a vampire is a lot harder than it was when he was a human. That doesn’t mean that he doesn’t like the process of getting high, though. There’s fun in it anyway, okay?

…Alright, fine, maybe he’s just coping. 

Either way, there’s a foolproof way to get the job done: getting Nam-gyu high, instead, and then drinking his blood. And it’s not like Nam-gyu ever objects; the motherfucker loves getting bitten. Thanos knows, rationally, that it’s because of the extra high the venom gives him as it sinks into his bloodstream to weaken him, but sometimes he wonders if Nam-gyu would still be into it if there was no venom at all. Just to feel Thanos’s fangs sink into his throat and eat him alive. 

Damn, he’s hard. Really fucking hard.

And right on cue: “Stop spacing out!” Nam-gyu (cycling back to the brat phase) complains, snapping Thanos out of his thoughts. While he’d been distracted, the little minx had taken off his shirt, leaving himself fully nude and spread out tantalizingly on Thanos’s bed. 

Thanos looks up to the ceiling and clasps his hands together. “Heavenly Father,” he begins to pray out loud, “thank you for this blessed meal that you have set before me. I promise to not take your divine gift for granted and to cherish it with respect and admiration. You’re the goat, man.” Thanos thumps his fist against his chest twice and holds a peace sign to the sky. “Amen!”

When he looks back down at Nam-gyu, the boy is giving him the meanest face Thanos has ever seen on anyone. “I’m ten seconds away from putting my clothes back on, Thanos, I swear,” he seethes. Oof. Aggressive. 

“I gotta say grace before I eat, my boy,” Thanos says, eyebrows knitted together. What is Nam-gyu not understanding about this? 

“You’re a vampire!” Nam-gyu screeches, “You’re, like, inherently against what the church stands for!”

Huh. Is he really? He’ll have to check Reddit later. Either way, Nam-gyu’s got a point on this one. Instead of getting freaky, Thanos is getting sidetracked. He’s gotta lock in. In god’s honor, or whatever. 

“Thanos!”

“I’m going, babydoll, chill,” he reassures as he starts to strip.

Nam-gyu stops complaining the second Thanos takes his shirt off and crawls towards him, oddly enough. Funny how that works. And it’s even funnier how Nam-gyu reacts when Thanos’s long, cold fingers start stroking his bare legs. His breathing stops for a second and—

“Your heartbeat always goes crazy when I touch you like this,” Thanos muses, slowly dragging his hands up and down Nam-gyu’s inner thighs. “Did you know that?”

“Shut up…” Nam-gyu mumbles. Pliant. Finally. “Just… Touch me, Thanos, come on…”

Thanos’s index ghosts over his entrance, motivating. “What’s the magic word?” 

“Please…” Nam-gyu whispers, jolting with a relieved noise when Thanos slips a finger in. 

Nam-gyu’s wet. Fucking soaked, actually. He wouldn’t stop complaining, but he’s been building up a tsunami in his boxers. What a lying brat. Not that Thanos particularly minds, obviously. But it’s the principle of it. 

“Thanos,” Nam-gyu whimpers after a few seconds, pawing at his naked shoulder. His cheeks are a delicious crimson.

“I got you, sweetheart, don’t worry,” Thanos shushes him. He knows what Nam-gyu wants without him needing to say it; he adds another finger.

Nam-gyu mewls, hips jumping up to meet Thanos’s hand. “Oh, fuck. That— hah, that feels good,” he babbles. His mouth is ajar as he pants while Thanos finger-fucks him. 

And he feels good, too. Burning hot inside, dripping, and, “For a dumb whore, you’re real fucking tight.”

Nam-gyu lets out a protesting whine. “I’m not a whore,” he whimpers.

That’s crazy. Blasphemous as fuck. “Had a whole ass date tonight, and you didn’t even go,” Thanos points out, and maybe his movements get a little rougher, a bit meaner as he recalls that. “Wanted to get fucked instead. What’s that make you, huh?”

Nam-gyu doesn’t respond to that. Instead, he just tilts his head back all the way and groans, “That feels so good. Don’t stop.”

This guy can’t even fucking admit he’s a slut. It’s kind of aggravating, actually. Because the question of ‘who could Nam-gyu possibly be seeing’ has been plaguing Thanos’s mind all day. He’s come up short for any answers, because Nam-gyu hates everyone. Everyone except Thanos.

Or so he fucking thought.

Nam-gyu cries out when Thanos adds a third finger, and Nam-gyu gasps, legs twitching as he tries to get away from the overwhelming pleasure. “‘S too much. Thanos, please, that’s too much,” he moans, eyes welling up. 

“Answer the question,” Thanos demands, speeding up. Nam-gyu writhes, letting out a dry sob. “What does that fucking make you, Nam-gyu?”

Okay, he’s definitely a lot more upset about this than he had previously thought. Maybe it’s because now that he’s reminded of what Nam-gyu looks like when he’s naked and horny, he realizes just how much he doesn't want anyone else having what he does. 

Because Nam-gyu’s his. And Nam-gyu, of all people, needs to realize that.

“F-fuck, Thanos, please,” Nam-gyu whines, moving up on the mattress to escape, but Thanos just uses his free hand to hold him down, keeping him in place. “It’s— It’s not—”

“‘It’s not’ what?” Thanos growls. “It’s not you being a dumb fucking slut? Cause that’s sure as hell what it seems li—”

“It was my dealer!” Nam-gyu finally shrieks, tears rolling down his face. “I was meeting my dealer.”

A record scratch echoes through Thanos’s head as he pauses. 

Because, hold up. Play that shit back. 

What did he just say?

“I— I lied to make you jealous,” Nam-gyu continues with urgency when Thanos doesn’t say anything. “Please…”

Okay…

Okay, okay. Everyone shut the fuck up, he’s trying to figure this out.

“You’re fucking with me,” Thanos deadpans as he pulls his fingers out. “Nam-gyu, tell me you’re fucking with me.”

“I’m sorry,” Nam-gyu croaks out as he tries to regain his breath. “I wanted… Wanted to see how you’d react.”

Manipulative. Fucking. Bitch. “You’re insane,” Thanos tells him. He’s literally a blood-sucking monster and yet Nam-gyu’s the most evil thing in the room right now. “An actual fucking sociopath.” 

“I don’t care,” Nam-gyu breathes out. “Fuck me, Thanos, come on.”

Thanos scoffs, even as his dick twitches at the sheer desperation in Nam-gyu’s voice. “You think you deserve that? You lied to me. Made me think I was some loser in a one-sided situationship. Why should I fuck you, huh?”

“Because…” Nam-gyu’s face scrunches up while he tries to think, but Thanos can sorta bet his mind is fuzzy from the drugs. “Because…”

“Take your time,” Thanos says drily. 

Nam-gyu eventually just whines, looking a little lost. Cross-eyed. High as balls. “I don’t know,” he mumbles weakly. “Just… please?” And then: “You can do whatever you want to me.”

Thanos’s interest is real fucking piqued. “Whatever I want?” he echoes. A slow, feral grin spreads over his face as he starts to imagine what that could entail. 

“Whatever you want,” Nam-gyu confirms, spreading his thighs. It makes Thanos zero in on the thick, pale skin there, and his fangs extend without him even meaning them to. 

With a growl, Thanos dives in, hooking one of Nam-gyu’s legs over his shoulder and then sinking his sharp teeth into his thigh.

Nam-gyu cries out at the sudden movement, the burning sting of flesh breaking. But Thanos doesn’t care. Nam-gyu’s blood is thick, warm, and sweet. How the fuck is his blood sweet? The guy’s gotta be magic or some shit. God knows he’s got a superpower for rage-baiting. It’s good that he’s got an inherently redeeming quality like this; makes it real easy to forgive him. 

Thanos drinks quickly but carefully. He might be hella pissed, but Nam-gyu’s a human. He’s fragile — not that Thanos would ever say that to his face; Nam-gyu would find a way to kill him all over again. But regardless, he’s gotta pay a crazy amount of attention to how much he’s drinking. 

Nam-gyu’s letting out these pitiful little noises, whimpering and shaking as he tries to relax and fulfill his end of the bargain. After all, this is the ‘whatever’ that Thanos wanted. He knew what he was doing when he made a deal with a vampire. It’s hard to feel too bad for him.

And speaking of hard — holy fuck is Thanos dangerously turned on by how pathetic Nam-gyu sounds when he’s getting his blood sucked out. The thigh’s different from the neck, obviously. The venom won’t kick in as quickly. This is pure, unadulterated pain that Nam-gyu’s taking like a champ. All for Thanos’s forgiveness. It’s so fucking cute. Thanos wants to eat him alive. 

“‘M sorry I lied,” Nam-gyu slurs out, undoubtedly woozy from blood loss. He reaches one shaky hand up to cup Thanos’s cheek as the vampire keeps drinking. “Only want you, Su-bong.”

The name drop is crazy. Manipulative as shit, even while Thanos is teaching him a lesson about being manipulative. It’s fucked up— 

—And unsurprisingly effective.

It’s got Thanos slowly, gently pulling his fangs out. He runs his tongue over the two punctures, letting his supernatural saliva quicken the healing process. In the meantime, Thanos strokes his other thigh, cooing at Nam-gyu’s cross-eyed expression. “Did so good,” Thanos praises softly. “Took it so well, baby.”

Nam-gyu weakly smiles up at him. “Can you… Are you gonna…”

Thanos searches his face for a clue as to what Nam-gyu’s trying to ask him, and then guesses, “Am I gonna fuck you now?” Nam-gyu nods. “Yeah, little one. I’ll fuck you.”

The relieved ass sigh Nam-gyu gives is too cute to even process. “Let me see him,” Nam-gyu requests. For a second, Thanos is nonplussed. 

And then he snorts. This fucking weirdo… “You wanna say hi before he goes inside you?” Thanos teases playfully as he undoes his belt. 

“I just like seeing him,” Nam-gyu responds, not even sounding defensive. It’s fair enough. 

Thanos quickly finishes unlooping the belt, then pulls down his pants and boxers in one go. His cock, hard and purple at the pierced head, springs out, jutting proudly against his stomach and twitching when Nam-gyu gives it his unadulterated attention. 

“There he is,” Nam-gyu coos with fucking stars in his eyes. Thanos might just get jealous of his own dick. To be fair, though; it is a pretty nice dick. Thanos has multiple five-star reviews. “Okay,” Nam-gyu says, leaning back and spreading his legs wide open. “Shop’s open.”

Oh, he’s high out of his mind. Which is not an inconvenience whatsoever — actually, it’s a little funny. It does mean that he isn’t prepared when Thanos flips him onto his stomach, though. He yelps, but settles when Thanos runs a large hand down his back soothingly.

He did promise Nam-gyu doggy, after all. Who is he to deny his favorite human anything he wants?

“This okay?” Thanos asks quietly, momentarily massaging the base of Nam-gyu’s spine. “Any strain?” Nam-gyu’s willing to do mostly anything during sex, but the ache in his thighs post-doggy if he’s not in a comfortable position always gives Thanos a headache from how much Nam-gyu complains about it.

“‘m good,” Nam-gyu sighs dreamily. 

“Okay,” Thanos murmurs as he lines himself up. He’s so happy he (and most importantly, his sperm) is dead — condoms are such a hassle. Plus it’s just so much nicer, the feeling of Nam-gyu’s slick folds as he rubs the head of his cock there, and—

“Wait!”

The word has Thanos stilling completely. He pulls away, hand leaving his dick and grabbing Nam-gyu’s shoulder instead, urging the boy to look at him. “What’s wrong?” Thanos asks worriedly.

Nam-gyu just slightly tilts his head to look back at Thanos, eyes half-lidded. “Don’t you need permission to come inside, fangs?” He giggles. Fucking giggles, the little hellcat. Back to this phase, then.

Thanos lets out a frustrated noise. “Damn it, Nam-gyu. You scared me.” He motions to his wilting erection.

“Aw, I’m sorry,” Nam-gyu — very disingenuously — apologizes with a tiny pout. He stretches out a bit, letting the curve of his back deepen and his ass stick higher in the air. Thanos’s mind short-circuits. “Just wanted to play by your rules, baby,” the human coos. 

Oh, good lord. It might as well be Thanksgiving the way Thanos has a full course meal in front of him. “It’s… Um…” He starts, suddenly distracted. What the hell had he been mad about again? “Uh…” 

“Su-bong,” Nam-gyu sings-songs lecherously. He subtly wiggles his ass in the air — the guy can get real slutty when he does coke. “Come inside,” he purrs. 

“Right,” Thanos hastily agrees, lining himself back up. He’d be embarrassed, but holy fuck. That shit got his dick and his fangs out and ready to sink into Nam-gyu. He got a little overwhelmed there. Anyone would, he consoles himself. He might be a supernatural creature, but Nam-gyu’s sex appeal is a whole different level of paranormal. 

They both moan as Thanos gradually enters, the vampire grabbing Nam-gyu’s waist to hold him at a good angle… And to hold him upright a little. The boy’s pretty faded. It’s a necessary precaution. 

“You feel so good,” Thanos groans as he bottoms out completely. Nam-gyu’s drug intake has him pretty loose; he doesn’t whine or whimper in pain like he usually does when Thanos is more than six inches in. He just took it all without a single complaint. 

“You… you too,” Nam-gyu pants out against the mattress. “You can move.”

If there’s a god, Thanos is gonna start praying to it the second this is over. He doesn’t hesitate, just grips both of Nam-gyu’s hips and forcefully thrusts into the warm, wet heat. 

Nam-gyu cries out, a startled, pleasured noise that Thanos takes as encouragement. After all, he can literally feel the proof of Nam-gyu’s arousal dripping down his shaft every time he pulls out to slam back in. 

“You’re so wet, baby,” Thanos murmurs, reaching one hand around to play with Nam-gyu’s clit. Nam-gyu whines, wiggling away as if to escape the overstimulating sensation and then forwards again. “So fucking high, too. Don’t even know what’s happening, huh?”

“Fuck me harder,” is Nam-gyu’s response. That’s a ‘no,’ then. And also sort of a ‘yes.’ A win is a win or whatever.

Thanos laughs through his nose, hand leaving Nam-gyu’s pussy as he focuses his efforts on doing as Nam-gyu asked; he pulls Nam-gyu’s hips back every time he thrusts forward, and it’s got Nam-gyu writhing like he’s burning from the inside out, gasping out little ‘ah!’s like he’s stuck on the first letter of the vowels. Hot as hell. It’s some cute shit, and it’s got Thanos speeding the fuck up as he chases his own pleasure. 

Which is damn easy, because Nam-gyu’s perfect. And he wouldn’t say that shit out loud because the guy’s already got a crazy ass ego — which is so confusing since he’s also got the biggest inferiority complex in the world — and would never let Thanos hear the end of it. But it can’t really be helped; Nam-gyu’s got a nice body, soft, warm skin that’s almost malleable as Thanos digs his fingertips into it, and he always lets out the prettiest sounds when Thanos fucks him the way he needs to be fucked: hard, fast, and with some degradation mixed in.

“You love this shit, don’t you baby?” Thanos laughs. “Love grinding back on me while I use you, huh?” Nam-gyu lets out a weak whine, shaking his head a little. Liar. “It’s okay, sweetheart. You don’t have to be embarrassed. I love it too.” 

He reaches around to grab the front of Nam-gyu’s throat, holding him up. The pulse throbs frantically beneath his fingers, as if praying for mercy in rapid morse code. With the other hand, Thanos grips Nam-gyu’s hair, yanking back his head. 

“Shh, baby, you’re okay,” Thanos coos when Nam-gyu wails at the pain that blossoms from the movement. He leans down til his cold chest is flush with Nam-gyu’s burning-hot back. “Doing so good for me,” he murmurs as he lets go of Nam-gyu’s hair to hold himself up. His other hand stays gripping Nam-gyu’s neck, though. He knows how much his boy likes the feeling of being choked like this — plus, he won’t deny that being in control of Nam-gyu’s breathing kinda has him on a power trip.

Thanos nips at the sensitive spot behind Nam-gyu’s ear, feeling the human shudder against him at the brief pain. It’s damn cute how much Nam-gyu’s body responds to him. And Thanos would be lying if he said Nam-gyu didn’t make him feel the same way. 

And then, as if it couldn’t get any fucking better, the motherfucker tilts his head a little to the side to give Thanos — and his fangs — more room.

Thanos’s pace falters, and Nam-gyu immediately reaches a hand back to blindly slap Thanos’s chest. “Keep going,” he complains, the words a little slurred. Fucking bratting out again. 

But Thanos doesn’t; instead, he lets go of Nam-gyu’s throat to trace the long column of pale skin that’s just been offered to him on… Well, he would say on a silver plate, but that would kinda kill him. On a gold plate? Good enough. “Nam-gyu,” he murmurs, nosing at the hot area. Blood. So much blood, and Thanos is so hungry for it. But first, “You want it?”

“Mhm,” Nam-gyu hums, his heartbeat — fuck, his heartbeat — staying perfectly normal. Not even scared. Like it knows Thanos won’t do anything to hurt it. 

“Say it,” Thanos says softly, fangs threatening to extend. It takes a lot of self-restraint to hold them back, but he would rather fight his own body for centuries than injure Nam-gyu. “Use your words. Say you want it. ”

“I want it,” Nam-gyu complies in a whisper. “Please, Su-bong…”

Okay. Okay, good. Thanos drives himself all the way inside of Nam-gyu, keeping his dick warm and Nam-gyu full. They both shudder at the same time. “Tell me to stop if you get dizzy,” Thanos warns. And, yeah, Nam-gyu knows; god knows they’ve done this a hundred times before. “Oh, uh… ‘Blood loss’ dizzy, not ‘high’ dizzy,” he clarifies.

Nam-gyu throws back a thumbs-up. Consent given then. Thanos feels his fangs lengthen, and he scrapes them gently against Nam-gyu’s delicate throat. Nam-gyu laughs a little, and, high as hell, “Stoppp!” he wiggles away. Thanos grins. “That tickles.” Giggly again.

“Alright, alright,” Thanos snickers. He brings Nam-gyu closer by the front of his neck. “Going in now, alright?”

“Kinda feels like it’s already in,” Nam-gyu playfully quips as he clenches around Thanos’s cock. Thanos’s hips jump a fraction at the feeling and grits his teeth to suppress the urge to keep fucking him. Focus. 

“Look who’s still not high enough to stop making dumb jokes,” Thanos remarks, but it comes out awfully fond. “Hold still.” 

The second Thanos’s fangs sink into Nam-gyu’s neck, the boy freezes up completely. No matter how much he trusts Thanos, it’s instinctive — evolutionary, even. What Nam-gyu’s doing right now, getting into bed with a predator, goes against every survivalistic reaction humans have developed over centuries. But he still tries, and Thanos loves him for it.

And he also sorta loves the way Nam-gyu squeezes tight around his dick while bearing down. That’s fucking hot as well.

It’s kinda bizarre. Thanos used to be hooked on a ton of shit, but this is the best and most addictive drug he’s ever tried: the way Nam-gyu melts when Thanos starts sucking his blood. It’s stronger than anything else he’s ever tried. The noises Nam-gyu lets out, whimpers and weak whines. But he never once pushes Thanos away. He stays put like a living blood bag all for Thanos’s sake.

Thanos satiates himself. Months of this has left him with an uncanny ability to draw the line between what’s necessary and what’s greedy. Nam-gyu’s dessert, not dinner. Which means he can’t go crazy, even though his instincts beg him to. He has to clench his fists to restrain himself. Just as Nam-gyu’s a human, Thanos is a vampire; there are things he’s biologically programmed to ache for. And while Thanos rationally wants Nam-gyu safe — and, well, alive — his vamp side wants to see Nam-gyu drained of every drop of blood he’s made off, pale as snow and dead as can be. 

He refrains. Has to. He loves Nam-gyu and, more importantly, Nam-gyu trusts him. Thanos would starve himself to death before betraying that trust.

Doesn’t mean that it’s not hard, though. Nam-gyu’s blood is hot, sweet, and laced. The drugs he took are heavy in his bloodstream, and Thanos is ingesting them by the mouthful. His cock keeps flexing inside of Nam-gyu’s tight warmth as he slurps and swallows, getting higher by the millisecond. 

Until finally, he can sense it: Nam-gyu’s heartbeat slows just a fraction. Thanos pulls away carefully, then licks over the area. Soothes it with his tongue, slow and gentle. Lovingly, like a sacred ritual. Because that’s exactly what Nam-gyu is: sacred. 

The human beneath him gives one whiny noise when Thanos finally lifts his head. Thanos laughs through his nose, tongue darting out to lick a stray drop of blood from a fang. “I’ve got you, baby, hold on,” he murmurs as he turns Nam-gyu over onto his back, making sure to stay inside him. 

He’s beautiful. Eyes all dazed and unfocused, two deep punctures on his neck, red and almost pulsing. But the prettiest part of him, Thanos’s favorite side effect of drinking from Nam-gyu is the dopey ass smile he’s wearing. Thanos loves it. Loves the way Nam-gyu is so clearly gone, satisfied and at peace. 

“You good?” Thanos murmurs. Nam-gyu doesn’t answer, just stares up at the ceiling, grinning, so Thanos nudges him. “Nam-gyu.”

Nam-gyu’s gaze lazily meets his. “Huh?”

“You feeling alright?” Thanos repeats, reaching out to cup Nam-gyu’s cheek. Nam-gyu presses needily into the touch, eyes fluttering shut. “Nam-gyu,” Thanos calls his attention sternly when the boy still doesn’t answer.

“W’sup?” Nam-gyu slurs, eyes still closed. 

Oh, lord. Maybe Thanos drank a little too much. Whoops. “Do you want water? Or a snack?”

“Nah,” Nam-gyu hums. “‘m good.”

…Yeah, Thanos will definitely feed him the second they’re done. But first, “you still want me to fuck you?”

Nam-gyu’s eyes open so quickly Thanos is momentarily startled. “Yes,” Nam-gyu stresses.

“Oh, now you’re locked in,” Thanos snorts. “I see how it is, baby, alright.”

“Duuude,” Nam-gyu whines. He clenches hard on Thanos’s dick, eliciting a low whine from the other. “Fuck me, Thanos, come o—”

The people who call vampires insatiable have clearly never met Nam-gyu, holy fuck. Thanos pulls all the way out and then slams back in, making Nam-gyu choke on his next plea. Not that the guy seems particularly upset about being interrupted — immediately, Nam-gyu’s legs wrap around Thanos’s flexing back like a koala. His foot knocks against Thanos’s spine, half encouraging and half impatient.

“‘s good,” Nam-gyu whines out, fucking drooling a little. The venom did its work quick. “Feels so good, Su-bong, please, please—”

“Please what?” Thanos asks, searching Nam-gyu’s scrunched up, blissed out face. “What, baby?”

But Nam-gyu just keeps on repeating, “Please, please, please, please, please,” in quick succession, getting more and more desperate by the second. Clearly Thanos isn’t getting any answers out of him, then. 

Thanos gets a hand between them to play with Nam-gyu’s swollen clit. Immediately, Nam-gyu’s back arches dramatically, and the boy lets out a cry that quickly evolves into a series of moans. “This what you wanted?” Thanos rubs deep, precise circles into Nam-gyu’s most sensitive spot. 

“Yesss,” Nam-gyu hisses, “just like that.”

Okay. Thanos doesn’t fold easy, but that shit’s pretty lethal. He fucks into Nam-gyu harder, faster. Getting them both where they need to be.

Nam-gyu comes first, keening with a loud, guttural noise, inhibitions long lost from venom and drugs. His insides pulse, massaging Thanos’s aching erection with devastating efficiency.

Thanos wants to keep going, he really does, but he can’t; he’s starting to feel the effects of the drugs, himself. And Nam-gyu feels so good, so perfect around him. His face, too; all sweaty, flushed red. His breathing, fast as Thanos keeps fucking him to the point of overstimulation. The way Thanos can still taste his blood in his mouth, on his tongue, behind his teeth, everywhere. 

All he can see, hear, smell, touch, and taste is Nam-gyu, gorgeous, sexy Nam-gyu. It’s enough and too much all at the same, overwhelming time. 

“I’m close,” Thanos warns, voice thin and kinda garbled. “Fuck, Nam-gyu, ‘m gonna come.

“Do it,” Nam-gyu whimpers, raising his thighs a little and clenching around Thanos’s cock, making himself tighter. “Go ahead, baby, finish in me.”

And, hey, maybe Nam-gyu was onto something earlier with the whole ‘vampires needing permission to come inside’ thing, because the second Nam-gyu says those words, Thanos practically erupts like a volcano. His orgasm barrels through him, a whole-body thing that has him shuddering as he keeps grinding shallowly throughout it. It’s mind-blowing in the way that it always is with Nam-gyu, his head spinning as he spills into the other over and over again.

Nam-gyu idly plays with his hair the whole time, helping Thanos come down. And when Thanos is finally done coming, he’s still smiling up at him, soft and sated. Gorgeous. Thanos kisses his sweaty forehead and it tastes like sea salt and pheromones.

He lowkey — highkey — wants to drink Nam-gyu’s sweat like a… Like a protein shake. He imagines putting Nam-gyu in a blender, laughs, and then feels tears form in his eyes. 

Okay, yeah, he’s definitely high. Jesus. 

“Uh… Thanos?” Nam-gyu snaps Thanos back to reality, shooting him a completely unnecessarily weirded-out look. “Are you crying?” 

“What? No?” He wipes his eyes and finds them wet. Yikes. “I thought about putting you in a blender,” he explains. “Made me sad.”

Nam-gyu’s brow furrows. “Why would you put me in a blender?”

“I—” Why the fuck was he thinking about putting him in a blender. “—don’t actually know.”

Nam-gyu stares at him for a moment, nonplussed, then snorts. “Weirdo,” he says fondly. “Get outta me, loser.”

“Nooo,” Thanos whines. “You’re so warm. Don’t make me go out into the cold, I’ll freeze to death.”

“You’re already dead, dumbass,” Nam-gyu teases. Thanos tilts his head as he thinks about it and, yeah. He’s got a point. “But I guess you can stay inside a little longer, as long as you don’t—”

Before Nam-gyu can finish the sentence, Thanos wraps his arms around him and rolls them both over, laying Nam-gyu down on top of his own naked body. 

“—move,” Nam-gyu groans. 

Fuck. Double yikes. “Oops.”

“Stupid bat,” Nam-gyu mutters, his head spinning from the sudden movement… and blood loss. “This is why some people are Team Jacob.”

“Yeah, people with no taste,” Thanos scoffs. That shit got him so offended when it first came out. Why the hell would people choose some giant dog over a sexy vamp? The consolation Thanos has is that, “At least you were Team Edward, right baby?”

“…”

Thanos waits for Nam-gyu’s instant confirmation, but he’s met with pure silence.

Hold the fuck on.

“Right, baby?” Thanos repeats tersely. There’s no fucking way.

Nam-gyu pointedly looks away and whistles. The fucking audacity. 

“You were Team Jacob?!” Thanos exclaims, astonished. “Why?!”

“Because vampires are conceited, self-entitled assholes!” Nam-gyu shoots back. 

And… Okay, fair enough. But still, ouch. 

“Doesn’t matter though,” Nam-gyu continues while Thanos is agonizing about this new development. “I’m Team Thanos. That’s the only thing that matters, right, Su-bong?” he purrs the fuck out of his name, squeezing his dick enticingly. Holy fuck…

“I thought you were tired,” Thanos points out when Nam-gyu clenches again. His hips jump up on their own.

“I am,” Nam-gyu agrees. “But I’m high on a bunch of shit, so, come on.” Then, goading, “Do your pervy thing and stuff me full of your vamp babies.”

Pervy? Oh, Thanos will show him how much of a perv he can be. He feels his fangs extend again when he grins. “You sure you can handle it, little human?” Thanos asks cockily.

Nam-gyu’s lip curls up into an equally arrogant smirk. “Bring it on, bat.”
