Between the chaos that came with the revival of Itadori Yuuji, as well as Satoru’s more-than-usual amount of missions during this period, somehow, he’d forgotten to feed.

It’s fine (until it’s not.)

After giving his mission report, the familiar prickles of an excruciating headache start to run down the back of his skull, signaling one thing, and one thing only—he’s low on blood.

He endures and endures, but, as he takes the familiar roads back home, the need to replenish his energy reserves automatically slots itself as his top priority, and he throws all logic and caution to the wind, following his pure, vampiric instincts as prey appears, and then he’s lunging for the kill—

Ah. He messed up.

Humans stood no chance against cursed beings in the first place, much less a vampire as strong as Satoru. Which was why he was now in the middle of cleaning up a big, bloody mess, instead of nourishing himself. 

“Shit,” Satoru mutters, staring at the woman he just accidentally killed. He wipes his mouth roughly, grimacing at the bitter taste of her blood. “Why’d you have to struggle so much? If you hadn’t, I wouldn’t have needed to be so rough…”

Even if the woman’s blood isn’t his ideal meal at all (too greasy and thick, no doubt from an unhealthy lifestyle), it should have been enough for him to get home. With nothing at all to satiate his hunger, he can feel his vision start to blur slightly at the edges—he needs to feed, and he needs to feed, fast. Could any part of the body be salvaged? He prods a pale, limp arm with his shoe, and tsks when he sees that the majority of the woman’s blood has already bled out, staining the pavement beneath. 

“...God damn it,” Satoru grumbles. 

His thumb hovers over Ijichi’s number—usually, he’d just obliterate any evidence of his feeding, but, today, Satoru just didn’t have enough energy. 

This is part of why he really didn’t like feeding on humans. 

Not only were they fragile, so he could only feed on them once, the guilt that comes with killing what you are supposed to save, as well as the vile feeling of lying to someone who trusts and respects you (he especially thinks of Yuuji’s kind, hazel eyes, always gazing up at Satoru with fondness and affection)...it eats at you from within.

“...So much for being able to feed on the way home,” he sighs. Now, he’d either have to go all the way to Shoko for blood bag, and she’d no doubt laugh at him, or, he’d just have to find another—

“S-Sensei…?”

Satoru’s entire body freezes. 

No. It couldn’t be.

But...Yuuji’s been going on night strolls. And Satoru could never not recognize the sound of Yuuji’s beautiful voice.

Satoru turns around, slowly, his jaw tightening when he smells the familiar scent of Yuuji’s blood, so sweet, so tantalizing, so delicious—

“S-Sensei...you—you’re—” Yuuji’s voice trembles as he takes a step backwards. 

Away from Satoru. It’s a detail that prevents Satoru from surging forwards and immediately sinking his fangs into the supple, enticing flesh of Yuuji’s neck.

“...Yuuji,” Satoru says gently , taking a slow, careful step forward. His hand twitches slightly when Yuuji swallows and takes another step back, one arm raised in front of him defensively.

The sight affects Satoru more than it should, and he feels a low, buzzing panic well up in his stomach. 

Even at the most violent, most terrifying displays of power from his sensei, Yuuji was never one to shy away. He always stayed close to Satoru. 

But, now, there is only fear and betrayal in those golden eyes—eyes that Satoru holds dear and loves so much—as Yuuji stares at the mangled, still-bleeding out corpse on the ground, and Satoru opens his mouth to speak, to explain— 

Sukuna’s mouth opens in a cruel, mocking smirk, right on the side of Yuuji’s face.

“Heh, would you look at that, brat. I told you so. Everyone at the school’s just a bunch of filthy hypocrites. Saving others? No, no, they’re no different from me—at the end of the day, they all kill.” 

“Yuuji,” Satoru tries again, more firmly this time, reaching a hand towards his favorite student. Yuuji wasn’t afraid of him. He couldn’t possibly be. Because, after all, why would he need to be? Satoru will never hurt him. 

He wants nothing more than to see Yuuji safe, to see him grow and smile—in their bleak, dreary world, Yuuji is the closest thing to the sun. And, despite being a vampire, Satoru would do anything to be close to this particular sun.

But Yuuji turns and runs, full-on sprints, and the sight of his retreating back hurts Satoru more than he thought it would.

“Yuuji—wait!” He calls out, mustering all of his strength to levitate his body into the air. He doesn’t even stop to wipe the blood on his face as he follows Yuuji from the sky, chasing after him with a feral sort of desperation, until Yuuji runs back to Satoru’s (their) home, slamming the door hard behind him. Satoru’s breathless by the time he arrives (really, Yuuji runs so fast), and he inhales deeply, tracing the scent of Yuuji’s blood until he reaches the basement door.

Before Satoru even gets his fingers around the door handle, his head throbs, once, twice, and he slumps forwards, exhausted and delirious from hunger.

“Yuuji,” Satoru says, tone desperate and pleading. “Please, open the door. Let me...let me explain.” 

He hopes he doesn’t sound too strained.

“Sensei...I...I didn’t know you fed on people,” Yuuji’s voice is muffled and sad, and Satoru can tell that Yuuji’s leaning against the door, can almost feel him from where his scent is the strongest. 

“...I try not to,” Satoru says weakly. 

I try not to because of you, he doesn’t say. 

“Did you...did you kill her?” Yuuji sounds so broken, and something inside of Satoru breaks too.

“...Yuuji, I—,” Satoru cuts off his sentence with a groan, grimacing as his head throbs in pain once more.

The door flings open, and Yuuji looks at him warily, distrust and betrayal in his pretty hazel eyes. There are unshed tears in between his eyelashes, and even though Yuuji looks so hurt, the pain in his expression softens into worry for Satoru’s condition, and something in Satoru’s chest—maybe his cold, icy heart—clenches.

“Yuuji, I promise you, I don’t usually—“ 

"Sensei. Did you kill her?” Yuuji’s eyes are burning, daring Satoru to say otherwise. He stares back, helpless, absolutely powerless in front of those depths of molten amber.

“...Yes,” Satoru says, and for the first time in his life, he doesn’t feel proud of his power. Of who and what he is on the inside. He doesn’t want Yuuji to see him like this.

“Oh, god,” Yuuji says shakily. His face crumples. “I…I can’t believe...”

“I have to drink blood to keep going, Yuuji. It might not look like it, but sensei is actually very hungry and weak right now,” Satoru tries his best to give Yuuji his usual grin, but it doesn’t reach his eyes. “Usually, Shoko has blood bags for me, but, today...there was no other way. If I left this house in my current state, I’d probably do it all over again.”

“...But, you didn’t have to kill her,” Yuuji grits out, wiping his eyes with his sleeve. 

Like this, he looks so small, so vulnerable, and Satoru wants to hold him close until both their pains mold together into one.

 “You can feed without killing...I...I thought you were good. Why couldn’t someone get it for you? I would have gotten it for you, why didn’t you—“

“It’s not that simple,” Satoru sighs, taking a step forward. He doesn’t miss the way that Yuuji flinches, and Satoru grimaces. It hurt him to see Yuuji like this. 

It would hurt you even more, if you knew what everyone else did, too.

“Tell me, then, so that I can understand,” Yuuji pleads, his eyes turning shiny with tears. “I know sensei wouldn’t just...just…”

“...Sensei was busy with missions recently, and…” Satoru trails off, taking a deep breath before he continues. He’s laying out a lot of vulnerabilities here. It’s probably the hunger getting to him. “...Yuuji being revived distracted me from my own problems. I was so happy, and I forgot. It crept up on me. I don’t feed every day, just once a week, sometimes two, and—”

Satoru flinches as another sharp stab of pain resonates throughout his head, and Yuuji automatically steps forward to steady him. Their skin brushes against each other, and the very human, very inviting heat of Yuuji’s palm almost makes Satoru lose control right then and there. 

“And?” 

“...I didn’t realize I needed to until it was too late.” Satoru finishes, smiling down at Yuuji sadly. 

“But—” Yuuji starts, “When you...feed on people, you...don’t kill them each time, right? She’s...she’s just the first one?”

Yuuji sounds so hopeful, and Satoru takes a deep breath before bursting that bubble.

“...Unfortunately, she is not. The venom from my bite...it...it makes them bleed out.”

“But, I try to be gentle,” Satoru adds hastily, when Yuuji doesn’t respond.

It’s half a lie. He’s not gentle at all, but he can not, will not tell Yuuji that before the younger man came into Satoru’s life, Satoru was ripping out throats left and right, was feeding whenever and however he wanted—

“...Oh.”

At his words, Yuuji visibly deflates, and Satoru watches silently as Yuuji shrinks into himself and takes a step backwards, the distance between them feeling like a wide, open chasm, similar to the one he felt in his heart when he heard that Yuuji died.

“Yuuji. Are you afraid of me?”

Do you still think I’m good?

“...A little,” Yuuji answers him honestly, and Satoru steps forward into the room, almost moaning as his senses are utterly bombarded by the scent of Yuuji’s blood. Under the warm glow of the lights, Yuuji’s neck looks absolutely divine, just begging for Satoru to sink his fangs into, but he can’t do it—not to Yuuji.

“...Don’t be. I would never hurt you, Yuuji. You’re...you’re precious to me.” 

He steps closer, eyes silently asking for permission, and Yuuji pads over hesitantly, standing in front of Satoru with a bashful expression.

“...I know you won’t,” Yuuji whispers, “but...other people…”

He hangs his head, and Satoru reaches forward to cradle his face, sliding his palms gently over the apple of Yuuji’s cheeks. His breath hitches when Yuuji closes his eyes and leans into the touch, nuzzling against Satoru’s palms.

It’s so trusting, so raw and intimate, that Satoru feels his chest tighten again.  

“...Cold,” Yuuji murmurs, shivering as Satoru caresses his eyelids with his thumbs. “Sensei, you’re so cold…”

“...And you’re warm,” Satoru smiles, moving to pull away. “I’m sorry, but I don’t have much longer. I’ll be back later. I need to...feed. I hope you understand.”

His hands slip off Yuuji’s face reluctantly, but Yuuji reaches up and entwines their fingers, refusing to let go even when Satoru tugs. 

“...Yuuji,” Satoru warns, “My self-control is wearing thin. If you won’t let go, then…”

“You have blood on your face,” Yuuji murmurs, one hand letting go of Satoru’s. He raises a hand to his mouth, and Satoru’s eyes immediately flick down, watching helplessly as Yuuji’s tongue darts out to slide wetly over a thumb.

“...Sensei,” Yuuji says, reaching to wipe the blood off Satoru’s cheek, “what if...you fed on me?”

It happens in a blur. 

Before he even registers his own actions, Satoru has Yuuji in his arms and is blinking them to his bedroom. He sets Yuuji carefully on the edge of his bed, watching as Yuuji tilts his head up slowly, staring straight into Satoru’s unwavering gaze.

“Yuuji. You’re sure about this,” Satoru says, clenching his fists at his side. He’s trying his hardest not to sound too desperate, like he hasn’t been wishing for this to happen. 

“You could get hurt.”

And Yuuji getting hurt was the last thing that Satoru wanted. He wanted to protect Yuuji from the world of curses, maybe even from Satoru himself, but…

“Yes, Sensei. I’m sure—I...I don’t want anyone else to die,” Yuuji says, voice laced with determination, but Satoru watches as his body begins to tremble with nervousness all the same. 

“And, um, since Sukuna is...a part of me, I think it makes me immune to poison. So, I’ll be fine. I think.”

“But you’re still—” 

“And if I bleed too much, we’ll just make Sukuna heal me,” Yuuji interrupts, beaming and sounding proud of himself. He’s too bright and radiant for someone offering themselves to a vampire, especially one with an appetite like Satoru’s, and Satoru sighs.

He doesn’t deserve Yuuji. No one does. 

“...I’m sorry that you have to do this, Yuuji-kun,” Satoru murmurs, moving to sit next to him. 

He leans against Yuuji’s shoulder and inhales, mouth watering at finally having the chance to taste the blood of his dreams, the one running through Yuuji’s veins.

“Is there somewhere specific you want me to bite?” 

“Uh, not really,” Yuuji flushes, turning his head to the side. The action has Satoru staring up at the smooth column of Yuuji’s throat, and his body pulsates with need. “Um...just...where you would get the most blood to drink? I know sensei’s really hungry, so…”

His sweet little Yuuji, always, always thinking about Satoru first, even in a situation like this.

“Then...sensei is going to bite your neck, okay?” Satoru smiles, reassuringly. 

“U-Um, okay,” Yuuji blushes, cheeks turning pink as Satoru scoots closer and places his palm gently on Yuuji’s nape.

“...Relax, Yuuji. Try not to be too tense.”

“R-Right,” Yuuji stammers, shivering as Satoru’s hand gently traces down the side of his neck. Satoru slips his fingers into Yuuji’s shirt collar, marveling at the warm, sun-kissed skin beneath his fingers. 

“Everything okay?” He asks, as Yuuji flinches from the cold. 

“Y-Yes.”

Satoru swallows as he tugs the shirt collar down to reveal a smooth collarbone, as well as the delicious curve of Yuuji’s neck. He leans in and inhales deeply, breathing in the scent of Yuuji’s blood as well as the natural scent that the younger man carried with him—citrus and peaches, ripe for the taking, and for someone to bite into them.

“It gets messy sometimes, so you should take this off.”

Satoru barely can keep his voice level, he’s absolutely famished. The second Yuuji’s shirt is off, Satoru gets an arm around his waist and lowers him gently into his lap.

Immediately, his hand is back on Yuuji’s nape, gently pulling backwards so that Yuuji bares his throat.

“S-Sensei…please feed quickly, I don’t want you to—”

“...Don’t worry about me. Stay still, so I can prepare your neck. You’re going to feel numb,” Satoru grits out, fighting the urge to bite into Yuuji hard and rough.

He calms down and slides his tongue against Yuuji’s skin, licking a thick, wet stripe just above Yuuji’s jugular. He repeats the motion, letting the venom from his saliva seep into Yuuji’s skin.

“A-Ah…” Yuuji gasps at the sensation, flinching slightly when Satoru slides his lips and tongue lower to mouth against Yuuji’s collarbone. “Sensei...that’s not—”

“You smell so good, Yuuji,” Satoru murmurs, feeling his fangs begin to elongate and sharpen as Yuuji’s neck glistens wetly before him. “Just relax...don’t be afraid...”

He gives Yuuji’s entire neck another lick before leaning back, watching as a soft red flush begins to run down Yuuji’s skin from his neck to his chest. 

“I’m sorry, but I can’t control myself any longer,” Satoru pants, his fangs at their full length now. “Yuuji, I’m—I’m going to bite now, okay?” 

“O-Okay,” Yuuji breathes.

His entire body is tense as he bares his neck obediently for Satoru, showing the smooth column of his throat. His eyes are squeezed shut, and Satoru can tell that Yuuji is absolutely petrified, can even smell it through his skin. 

“Shh, sensei will take care of you,” Satoru whispers, looming over Yuuji’s trembling form. 

“I-I know. I...I trust sensei.”

It’s the fond and affectionate tone in Yuuji’s voice that rips the last of Satoru’s restraint away. He lets himself go and falls into the abyss that is hunger, eyes growing feral and wild as he feels his fingers curl around Yuuji’s nape, tugging and squeezing around his neck, exposing more and more of his throat. 

He smells so good, so sweet, so ripe—

Satoru sinks his fangs into Yuuji’s skin, remembering to bite down as gently as possible at the very last second, but even then, Yuuji cries out in pain immediately. 

“A-Ah—uhn—“ Yuuji whimpers as Satoru increases the force of the bite, his body going limp as Satoru’s venom begins to enter his bloodstream.

The effect is instantaneous, and Satoru almost moans in pleasure as Yuuji’s blood begins to gush into his mouth. 

There is no going back after this. In fact, there will never be anything after this—nothing will ever compare to the first saccharine drop of Yuuji’s blood hitting his tongue.

He’s never had something so perfectly sweet, so rich in flavor. Yuuji’s blood floods Satoru’s mouth, coating over his teeth, his lips—

It runs down the back of his throat, hot and inviting, warming his entire body up, and this time, Satoru does groan from it, gripping into Yuuji’s arms tighter as he drinks what he imagines to be blood that’s fit even for the gods.

Without a doubt, Yuuji is the best thing Satoru has tasted—ever. And he knows he won’t be drinking from anyone else after this, won’t share with anyone else after this.

No one else even has the right. Yuuji’s blood will be for Gojo Satoru, and Gojo Satoru only, for he is the strongest.

“Ah—s-sensei,” Yuuji gasps as Satoru begins to suck, wanting more of that liquid gold inside him. He can’t help it as he sinks his fangs in a little deeper and bites little rougher, letting his lips close around Yuuji’s skin, and Yuuji shivers in his arms, a desperate, needy moan leaving his mouth.

“S-Sensei—hngh—“

His breathing is becoming more and more ragged now, and Satoru notices that the skin beneath his palms is heating up too quickly for it to be a normal reaction—Yuuji’s temperature climbs and climbs, reaching the point of being feverish. 

“S-Sensei—“ Yuuji whimpers, high-pitched and breathy, and Satoru forces himself to pull off Yuuji’s neck, concerned. “S-Sensei—I’m—”

“Yuuji, what’s wrong? Are you alrig—“

He freezes when he sees the state that Yuuji is in—his entire body is trembling, flushed with a soft, rosy pink, his pupils dilated and breathing erratic. 

Blood trickles down from the incisions that Satoru left and he watches as the droplets begin sliding down Yuuji’s skin, lower, and lower, trailing through the supple skin of his chest—

“S-Sensei—my b-body, it’s—it feels hot,” Yuuji whimpers, unshed tears beginning to fill his eyes. “P-Please, help me—“

Yuuji shivers and presses closer to Satoru, losing his balance in the process, a soft whine slipping out of his mouth when Satoru places a hand on his waist to steady him.

Yuuji shifts his hips and clenches his thighs together, and Satoru’s eyes flick down to his lower body, where Yuuji’s arousal is already evident, straining through the fabric of his pants. 

Satoru has an idea of what it could be, but...he’s never encountered this with any of his previous meals before. Did Yuuji’s immunity to his venom simply reduce its effects to that of a very potent aphrodisiac? 

“Yuuji, look at me,” Satoru presses a gentle palm against Yuuji’s forehead, and his concern grows when Yuuji whines, craning upwards immediately into his palm.

“Gojo-sensei, p-please,” Yuuji begs, slumping forwards against Satoru’s chest. “H-Help me cool down, it’s—it’s too hot—”

Satoru swallows, watching as more blood trickles out of Yuuji’s wound, his lucidity slowly slipping away as the scent and sight before him beckons his vampire instincts forward like a siren’s song.

“Yuuji, you don’t know what you’re asking for—this is sensei’s fault, I should’ve—”

Warm hands fist into his collar, and Satoru’s eyes widen as Yuuji tugs him down, tilting his head upwards to slant their mouths together in a clumsy kiss. 

“P-Please, sensei, I—I want—I need you—” Yuuji begs, the gold of his eyes almost completely swallowed by the black of his pupils. 

Satoru shouldn’t. He really shouldn’t, especially when he was the one that caused this in the first place. 

He should get Yuuji to Shoko, or some medicine at least—

But Yuuji’s asking so nicely, and Satoru won’t deny that he feels something deeper for Yuuji, won’t deny the longing that lodges itself in his throat when it comes to this beautiful boy with a bleeding heart.

He longs for the warmth of Yuuji’s smile, the crinkles of Yuuji’s eyes when he laughs. He wants to stay with Yuuji, so that he can feel human again. 

Because Yuuji is, and will always be, Satoru’s sun.

And who was Satoru to deny the sun, especially when he was absolutely powerless in front of it? 

“I’m here. What do you want me to do, Yuuji?” Satoru murmurs, watching intently as Yuuji tilts his head back and bares his throat, looking up at Satoru with a desperate, needy expression. 

“B-Bite me again, sensei—h-hold me, touch me, anything, as long as it’s you—“

Yuuji’s absolutely begging for it, and Satoru’s willpower crumbles. No one but him will be able to have Yuuji like this.

“...Fuck,” Satoru grits out, and it’s the last of his self control. 

Any sort of restraint he still holds is ripped away from him, and he snarls, surging forward to press Yuuji into the bed. He begins lapping at the blood that's trailing down Yuuji’s chest, chasing after the droplets, dipping his tongue into Yuuji’s collarbone, then his navel, before finally licking back up to circle around a hardening nipple.

“S-Sensei—ah—uhn— “

Yuuji moans and whines, high-pitched and breathy, and Satoru drags a hand through the blood on Yuuji’s skin, admiring the beautiful ruby color of it before smearing it across his chest.

It’s wet and sticky, and he feels his own breathing become ragged as he trails his fingers down Yuuji’s side to leave a bloody handprint on his hip.

“S-Sensei—please—d-down there—f-feels empty, I need you—”

Satoru groans softly—those sinful words sound so pretty coming out of Yuuji’s sweet little mouth.

“Oh, don’t worry, Yuuji—I’ll be filling you up soon,” Satoru says, voice low, tone possessive, and Yuuji’s entire body trembles in response.  

“Y-Yes, sensei,” Yuuji gasps, the sound desperate and breathy as Satoru’s thumb traces over his hip bone.

“You look so pretty like this, Yuuji…all flushed and panting, so eager for me...”

The scent and sight of that blood—Yuuji’s blood, the blood that Satoru has been wanting to drink since he first smelled the boy on that rooftop—has Satoru experiencing arousal so intense that he’s ripping and shoving his own clothes off, before reaching down to tear off the rest of Yuuji’s clothes.

He hasn’t felt this way in years, hasn’t had a body so warm and alive beneath him in years. He didn’t even know he could feel desire inside him again. 

No one wanted to sleep with an icicle, and even if they did, Satoru didn’t even know if he could get hard properly, would probably end up ripping their throat out anyways before anything even happened.

But, this…

This is different.

Maybe it’s because of Yuuji. Maybe it’s because of Yuuji’s blood inside him. Whatever it is, it’s igniting a fire within Satoru, pushing him to consume, to claim, to possess—

Satoru presses his palm against the wound on Yuuji’s neck, coating his hand with a thin layer of blood.

“Your skin is so smooth, so perfect…”

He leaves faint handprints all over Yuuji’s skin as he takes in the entirety of the younger man’s naked body below him, watching Yuuji writhe on the sheets with each of his touches.

It’s an obscene, crazy thought, but Satoru wants to make him bleed some more, wants to cover the canvas that is Yuuji’s body with bruises and bites, wants to mark that sun-kissed skin all over with red, sticky handprints—a masterpiece made by Satoru, for no one but himself.

He can already picture it—Yuuji looked the best in red, after all.

But first, he’s still hungry. 

“Oh—ah—sensei, Gojo-sensei—” Yuuji’s practically crying as Satoru settles between his thighs and pushes his legs apart, mouthing and licking at his inner thighs. 

“A-Ah—!”

Satoru bites into the softest part of Yuuji’s muscular thighs, groaning in pleasure as that deliciously warm blood rushes into his mouth again, and Yuuji cries out when Satoru begins sucking on the sensitive skin. He drinks his fill slowly, savoring each drop of Yuuji’s blood that flows through his mouth.

He digs his fingers into Yuuji’s thigh and feels the muscle flex beneath hands, feels the shiver that wracks through Yuuji’s body as Satoru slides his hands beneath to slip his fingers into the cleft of Yuuji’s ass.

“Hngh—s-sensei…” 

Satoru pulls off, licking at the wound until there’s only a trickle of red, nuzzling into Yuuji’s inner thigh and looking up at his face the whole time, burning the needy, teary look on the younger man’s face into his memory.

The new bite from Satoru has Yuuji shaking and trembling even more as a new dose of venom courses through his veins, clouding his senses thoroughly and making him sensitive to even the slightest touch from Satoru.

“S-Sensei—“ Yuuji whimpers, digging his heels into Satoru’s upper back, trying to get Satoru’s mouth and hands back on him. “P-Please—touch me more, I—I’m burning up—“

Satoru obliges, wrapping his fingers around Yuuji’s hard, leaking cock, and the guttural moan that he gets in response is one that he’ll never forget.

“How’s this, Yuuji? Is sensei making you feel better?”

“Ah—so cold, feels good—“ The words tumble out of Yuuji’s mouth, and when Satoru squeezes and gives him a firm upstroke, Yuuji keens, bucking his hips up into Satoru’s fist desperately.

“Hngh—ah—“ Yuuji chases Satoru’s grip, his eyes squeezed shut and head thrown back in pleasure as Satoru jerks him rough and fast, increasing the pace when Yuuji’s moans get more and more breathless, more broken—

“That’s it, you’re doing so well, Yuuji...sensei’s going to help you cool down, just like this...“

He swipes a thumb over Yuuji’s slit, smearing the leaking pre-come all over, and Yuuji mewls, crying out when Satoru does it again, and again, faster, harder—

“S-Sensei, I’m—“ Yuuji sobs, his body arching upwards on a broken cry as he comes, his warm spend splattering all over Satoru’s hand. “Hngh…”

His body goes limp and pliant, but his cock’s still achingly hard, and Satoru slides his fingers along the underside of it, cooing when Yuuji shivers and arches into the touch.

“...Yuuji-kun, just look at you,” Satoru purrs, bringing his hand to his face to lick Yuuji’s come off. “I think my venom ended up being an aphrodisiac for you, but...who knew it’d affect you this much…”

Satoru presses close, letting his body envelop Yuuji’s, reveling in the soft, satisfied sigh that Yuuji makes when he slides against the coldness of Satoru’s skin.

“S-Sensei, closer—it’s still—I’m still burning,” Yuuji pants, looking up at Satoru with half-lidded eyes. “I-It’s too hot...c-cool me down, please...from the inside...“

“...Anything for you, Yuuji-kun,” Satoru croons, one hand fisting into Yuuji’s nape to pull his head back, admiring the set of incisions his fangs left on the boy’s throat. “I’ll fuck that heat out of you, don’t worry. But, just one last bite...”

“Ah—angh—sensei— “ 

He sinks his teeth into the side of Yuuji’s neck once more, drinking and taking until he’s satisfied. He’s never felt so full, so sated, his body vibrating with energy as Yuuji’s blood rejuvenates Satoru from within.

He wants more. He wants all of it. 

Snarling, he sinks his fangs deeper, one hand fisting around Yuuji’s cock, ignoring the pained, high-pitched cry that Yuuji makes when Satoru closes his eyes and puts more force into the bite—

“S-Sensei, I...” Yuuji’s arms wind over Satoru’s shoulders, his legs wrapping around Satoru’s waist desperately as his blood continues to be drained. “I’m getting dizzy…”

Satoru feels Yuuji’s grip around him start to weaken, and he lets go of Yuuji’s length, eyes flying open at the sudden spike in cursed energy.

“Well, well, well—Six Eyes, aren’t you taking a bit too much? You’re gonna suck the brat dry at this rate,” Sukuna’s voice comes out from where Yuuji’s palm is pressed against Satoru’s shoulder. 

“You planning to kill him or what? How ironic, considering how he feels about you,” Sukuna mocks, laughing cruelly at the weak slap that Yuuji gives him.

If Sukuna continues talking, Satoru doesn't hear the rest, he’s too hung up on the second half of Sukuna’s sentence. How Yuuji feels about him—it’s something that he wasn’t sure if he ever wanted to be confirmed, but now...

Satoru pulls off Yuuji’s neck, casting a heavy glance over Yuuji’s pale, clammy face. He won’t admit it, but he knows he’s taken too much from Yuuji, knows he’s taking advantage of Yuuji’s kindness.

Of his feelings.

But Sukuna’s appearance promises Yuuji’s recovery, as well as an infinite supply of blood. He’ll allow the curse’s intrusion in his time with Yuuji, just this once.

As long as Sukuna doesn’t test Satoru’s patience here, things will be fine. Satoru just doesn’t like sharing what’s rightfully his.

It makes the cruel possessiveness in his body roar to life, but it’s okay—he’ll make it up to Yuuji later.

“...Then why don’t you pump some blood into him, Sukuna?” Satoru pulls Yuuji’s arm off his shoulders to look the curse in the eye. 

“...And why should I do that? I’m not on your side. I could care less if a mongrel like you goes hungry—“

“Oh, but Yuuji-kun’s so tasty, and I can’t control myself. And since you won’t heal him, I guess you’ll die too, slowly, as I drain you both dry. A pitiful ending for the King of Curses, don’t you think?” 

“Why, you—“

“Times running out, King of Curses,” Satoru chuckles, squeezing around Yuuji’s wrist where he knows Sukuna can feel it. “Go on, heal him.”

Silence fills the room, to the point where Satoru can hear Yuuji’s decreasing heartbeat. If Sukuna truly refuses, then it’ll work out in Satoru’s favor either way. He’ll just have to do the unspeakable and bring Yuuji back to life, as a vampire—

“...You’re both ingrates. Making me, the King of Curses, turn my vessel into some shitty vampire’s endless meal...Six Eyes, when I take over this body, I’m gonna kill you first—“

Now that he knows Yuuji’s going to be fine, Satoru’s tired of the curse’s low, annoying drawl. He muffles the curse with a soft smack, leaving a bloody stain along Yuuji’s cheek. 

“Sorry, Yuuji-kun,” Satoru murmurs, leaning in to lick at the mark, feeling the familiar rush of blood and life underneath Yuuji’s skin again. 

“S-Sensei,” Yuuji breathes, sighing softly as Satoru’s tongue traces up to the shell of his ear. “Cold…” 

Yuuji’s cheeks are back in all of their rosy splendor and Satoru kisses one tenderly, before moving his lips up to Yuuji’s temple. 

“Yuuji. What I said to Sukuna earlier—I didn’t mean it towards you, okay? I’d never want you to die.” 

“...I know. 

Yuuji nods, eyes fluttering shut as Satoru’s kisses brush over his eyelid, his nose, the corner of his mouth—

“You’re still burning up,” Satoru murmurs, pressing his forehead against Yuuji’s. “Sukuna can’t heal that, huh?”

“Y-Yeah—b-but, sensei’s body is helping me feel better,” Yuuji’s hand hesitantly presses against Satoru’s chest, his expression turning shy as he traces over Satoru’s muscles. 

“But the inside...the inside still burns—sensei, down there, I’m—“

“Shhh, Yuuji,” Satoru whispers, breath hitching at the scorching warmth of Yuuji’s hand, “I know. Let sensei help you, as thanks for your delicious blood.”

“Am I...tasty?” Yuuji asks, blushing, and Satoru blinks at him before his mouth curls upwards into a fond smile. 

Leave it to Yuuji to ask the most endearing of questions, even when they were in a situation like this.

“More than tasty. Yours is the best I've ever had.”

At his words, Yuuji’s cheeks bloom scarlet.

“...Oh. I’m...I’m glad? What do I taste like?” Yuuji’s eyes are big and wide as he cocks his head to side, considering. “Oh, wait. Blood probably tastes different for you, huh?”

Satoru chuckles.

“...Sweet. You taste sweet, like honey for the gods.”

“Oh.” Yuuji blushes, averting his gaze. “I...that’s…”

“You wanna try?” 

Before Yuuji can respond, Satoru tilts his head down to lap at Yuuji’s bleeding neck before slotting their mouths together, sliding his tongue alongside Yuuji’s, swallowing down the soft whimpers that slip past Yuuji’s lips.

“Blegh. Tastes like metal,” Yuuji mutters, grimacing after they part for air. 

“Well, blood contains iron, Yuuji. But to me, yours is the best,” Satoru whispers, licking a wet stripe down the front of Yuuji’s throat and feeling somewhat disappointed that Yuuji didn’t comment on the kiss. 

Undeterred, he curls his fingers around Yuuji’s cock once more, smiling as Yuuji’s breath immediately hitches.

“Now, let’s get to cooling you down...”

“O-Oh—“ Yuuji immediately begins moaning, arching upwards as Satoru’s hand strokes him hard and fast, his mouth falling open in a silent cry. 

Satoru rubs a thumb over the slit again, and Yuuji’s knuckles turn white as they fist into the bedsheets. He tightens his fingers around Yuuji’s length, milking the spurts of pre-come that begin flowing from the tip, as well as more cute sounds from his mouth. 

“Why don’t you get these wet for me, Yuuji-kun?” Satoru slides his fingers into Yuuji’s mouth, his own cock throbbing with arousal as he watches him part his mouth wide, obediently working his tongue over Satoru’s fingers.

Satoru enjoys the view more than he should, unable to tear his eyes away from the red flush of Yuuji’s body, of the wetness in the corner of his eyes as he fucks up into Satoru’s fist.

“Ungh—hgh—“ Yuuji makes a breathy whine as Satoru strokes him faster and shoves his fingers in deeper, fixated on the way that Yuuji doesn’t even gag once.

He could watch his fingers disappear into the wet, warm heat of Yuuji’s mouth forever, but right now, he wants to watch his fingers sink into somewhere else.

“...I think that’s enough,” Satoru murmurs, removing both his hands from Yuuji, gently shushing him when he whimpers at the loss of Satoru’s touch.

“Shh, I’ll take care of you even better now, okay?” Satoru soothes, leaning back and pushing Yuuji’s legs apart to settle between them.

The still-oozing bite marks on Yuuji’s inner thigh awaken a deep, primal need inside Satoru, and despite being full, he wants to bite into Yuuji again, wants to feel the clench of Yuuji’s thighs around him as he feeds.

But Satoru’s taken enough from Yuuji today. It’s about time he returned the favor.

“Does it still feel hot?”

“Y-Yes,” Yuuji whimpers, tears beginning to gather up in his eyes. “N-Now that you’re not touching me, i-it hurts—“

Another pang of arousal resonates through Satoru’s body, and he lets out a shaky breath. The vampire side of him wants to hold Yuuji down and fuck into him, rough, fast, hard, wants to make it bloody, make it hurt—

But his human side (or, what’s left of it, knows that Yuuji deserves better.)

Satoru hasn’t fucked anyone since he turned, doesn’t even know if he remembers how it feels to be inside someone, or to have someone inside him. His vampire side never craved any intimacy, deeming it a weakness.

But he’ll try. For Yuuji. 

“Relax for me, okay?”

His finger traces over Yuuji’s rim, before pushing in, slowly, to the first knuckle. Even with one finger, Yuuji’s tight, and warm, his inner walls clinging around Satoru like they never want him to pull out.

“Hngh—ah—s-sensei,” Yuuji responds immediately, fisting into the sheets as Satoru continues to push deeper. 

“Everything okay?” 

“Y-Yes—j-just need m-more,” Yuuji whimpers, wiggling his hips. “M-More, sensei—oh—ah—ahn—“

Yuuji’s voice breaks as Satoru adds another finger, pushing both to the last knuckle, feeling around inside Yuuji until he finds a particularly warm spot and presses.

“Ah—!” Yuuji mewls, a shudder wracking through his body. 

“Oh, you liked that, didn't you?” 

Satoru curls his fingers and presses into Yuuji again, harder, and Yuuji rewards him with a beautiful, broken moan, his body arching off the bed.

“S-Sensei—please,” Yuuji pleads, covering his face with a trembling forearm. “I’m—I can’t, I feel like I’m going crazy—“

“It’s okay,” Satoru murmurs, slowly starting to fuck his fingers in and out of Yuuji’s hole. “Go crazy. Sensei will take care of you.”

He drills his fingers against Yuuji’s prostate, scissoring them wide and curling them just so, watching as Yuuji falls apart with each thrust, until he’s drooling and panting into the bedsheets.

There’s a small droplet of blood sliding down Yuuji’s neck from where Satoru bit him twice, and Satoru closes his lips around it just as it pools in the divot of Yuuji’s collarbone, sucking a bruise into the skin there.

“S-Sensei—sensei—“ Yuuji keens, his walls clenching and fluttering around Satoru’s fingers on a particularly deep thrust, and when Satoru wraps a hand around hid leaking cock, all it takes is three wet, sloppy strokes before Yuuji’s coming with a sob, his head falling onto the bed like a ragdoll.

Satoru milks the cock in his hand some more, watching the rise and fall of Yuuji’s chest. Yuuji’s body is so limp, so pliant, and Satoru runs the back of his hand against Yuuji’s forehead, relieved to find his temperature a bit cooler than before.

“You look better,” Satoru murmurs, watching fixedly as Yuuji’s amber eyes flutter open again. He slides the hand on Yuuji’s forehead down to cradle Yuuji’s cheek.

“Still burning?”

“...Not as much,” Yuuji sighs, a soft, breathy noise leaving his mouth when Satoru’s hand gently fists into his nape again. 

“...Heh. Are you hungry again, sensei?” Yuuji gives him a tired smile, baring his throat for Satoru once more.

“No, I’m pleasantly full,” Satoru grins, tugging Yuuji’s head back some more. He leans close, his lips closing around the skin just below Yuuji’s ear. “I just like seeing you like this, like you were made to be bitten by me…”

He slides his tongue down Yuuji’s neck, over the bite marks, lapping up the beads of blood from the wounds like they were remains of his favorite dessert.

“...Yuuji,” He leans back, staring into Yuuji’s eyes. “Tell me. About what Sukuna said earlier—about how you feel about me—”

Yuuji’s furious blush tells Satoru more than he needs to know, and he chuckles.

“...Don’t laugh,” Yuuji pouts, turning his head to the side. “I just...I like being with sensei, okay?”

“And I like being with Yuuji-kun, too.”

“...I don’t think it’s the same ‘like’ as mine,” Yuuji says, voice barely a whisper. 

“Then what type of ‘like’ is Yuuji-kun talking about?”

“It...it’s the kind of ‘like’, where I like it when I can help you, and take care of you,” Yuuji explains, his cheeks turning pink. He swallows before continuing. “It’s...the kind of ‘like’ where I want to be bitten by you, where I want to kiss you, where I still want you to…”

Yuuji trails off, face flaming.

“...Where I want you, to f-fill me up,” he finishes, voice small, eyes absolutely refusing to look in Satoru’s direction. 

Satoru groans. He’s so hard that he could very well lose it with just the smallest hints of friction against his cock, and while he wants nothing more than to fuck into Yuuji’s tight, inviting heat, but he didn’t want to if Yuuji’s mind was clouded with the effects of his venom.

But, now...with Yuuji’s confession in the air between them…

“Yuuji,” Satoru slides a finger under his chin, beckoning Yuuji to look at him, “I don’t remember saying I didn’t want to do any of those things. Besides, we’ve already kissed, and I’ve already fingered you open—“

“...!” Yuuji’s eyes widen, a rosy blush tingeing his cheeks. “S-Sensei—!”

Satoru chuckles.

“I think that Yuuji is the first person in a long time to get sensei to feel like this,” Satoru gestures down to his achingly hard cock. It would be comical if he wasn’t trying to confess. “So, don’t you think that sensei’s ‘like’ is probably similar to yours?”

“...B-But, I’m not—” 

Satoru leans forward, pressing a chaste kiss against Yuuji’s lips. 

“Don’t think too hard. I’m just saying that I like Yuuji-kun,” Satoru says, smiling as Yuuji stammers and flushes cutely. “Your blood is tasty, and one else spoils me like you do~” 

“S-Sensei—” 

Satoru kisses him again, fisting his hand into Yuuji’s nape, feeling a tendril of possessiveness curl inside of him when Yuuji melts into the touch, a soft and pliant expression on his face once more.

“So, if our ‘like’ is the same, then I think the last thing I haven’t done yet, is fill you up,” Satoru smiles, innocently, climbing over Yuuji until he has the younger man’s wrists pinned down into the bed.

“So, let’s cross that off the list, shall we?”

Satoru exhales shakily as Yuuji’s lips close over the head of his cock, his warm, wet tongue gently lapping at his length until a low fire ignites in his belly, fueled by the heat from Yuuji’s mouth.

“You’re doing so well, Yuuji,” Satoru croons, sliding his palm against the bite wounds on Yuuji’s neck. With the same hand, he reaches to cradle Yuuji’s face, eyes growing half-lidded as he smears a thin layer of blood across his cheek. 

“Yes, just like that—I know you can take me deeper,” Satoru shudders, pushing further into Yuuji’s mouth. 

Yuuji makes a muffled noise around his cock, and the vibrations from his throat has Satoru groaning in pleasure. 

He begins to fuck Yuuji’s mouth slowly, letting him take a little more each time, watching as Yuuji’s eyes become glassy and glaze over with pleasure, adoration, something that could even be love—

The tip of his cock hits the back of Yuuji’s throat, and Yuuji doesn’t even flinch, just takes it like his mouth was made to warm Satoru’s cock.

“F-Fuck,” Satoru grits out, eyes flicking down to the unshed tears in Yuuji’s eyelashes. “Yuuji, you’re doing so well—I bet you could cum, just like this, with my cock down your throat—”

“Mmm,” Yuuji moans around him, and Satoru begins to fuck in and out a little faster, a little rougher—

“Oh, god—” Satoru groans, feeling the pleasure in his body spike, before pulling Yuuji off his cock, watching intently as a string of spit and pre-come dribbles out of Yuuji’s lips.

“You always were a fast learner, Yuuji-kun,” Satoru pants, splaying one hand against Yuuji’s chest to push him back onto the bed. “Now, let sensei reward you for your efforts.”

“S-Sensei, p-please—I need—” Yuuji pleads, parting his legs wide for Satoru to settle between them. 

“I know,” Satoru soothes, fingers curling around the soft skin behind Yuuji’s knee to hoist a lean, muscular leg over his shoulder. “Don’t worry, I know…”

From this angle, he can see the bite marks that he left earlier on Yuuji’s inner thigh again, and the urge to bite washes over him again.

“Yuuji. You want this,” Satoru says rather than asks the question, lining his cock up with Yuuji’s twitching hole. He traces his hand over it, feeling it flutter beneath his fingertips.

“...Yes,” Yuuji pleads, digging his heel into Satoru’s back. “Yes—s-sensei, please—it’s so empty, I’ve waited this entire time, I want to feel you inside—“

“...Alright.”

And then, Satoru’s pushing in, groaning in tandem along with Yuuji as the tight heat of Yuuji’s hole surrounds his length immediately, squeezing and sliding sinfully against every inch of his cock. 

If Yuuji’s skin was burning, then his insides are absolutely scorching—it feels like sinking into something akin to rapture, and Satoru moans as he bottoms out, sheathed inside Yuuji to the hilt, letting wave after wave of heat and pleasure wash over him as Yuuji’s walls clench and flutter around his cock.

“Yuuji,” Satoru groans, digging his fingers into Yuuji’s hips, turning his head to mouth along the skin of Yuuji’s lean, irresistible calf. “God, Yuuji...you’re so tight…”

“...S-Sensei—y-you’re so deep,” Yuuji whimpers, tears finally spilling from his eyes as Satoru scrapes his fangs against his ankle. “I-I can feel the coldness inside...i-it feels good…”

They stay like that for a moment, Satoru letting Yuuji adjust to his size, before he starts to move. 

The first smooth slide of his cock within the perfect, inviting heat of Yuuji’s hole is something short of heaven, and Satoru almost comes right then and there.

He fucks him slowly and tenderly, letting his cock slip in and out of Yuuji’s hole at a languid pace, angling his thrusts so that he can grind against the area of Yuuji’s prostate each time.

“Hngh—a-ah—s-sensei,” Yuuji cries out, tightening his arms around Satoru’s shoulders. 

It’s entirely too intimate for Satoru, especially the unconditional warmth of Yuuji’s skin, but he clings to it in return, tucking his face into the crook of Yuuji’s shoulder and gently lapping at the beads of blood that are still trickling down the side of his neck.

“A-Agh—s-sensei…” 

Halfway through, Yuuji’s eyes flutter shut as tears begin to flow freely from his eyes, and Satoru commits the sight to memory, wanting to physically keep each whimper and moan that falls from Yuuji’s lips.

He wants to keep this moment between them in his mind forever, wants to preserve and stay within the rose-tinted lenses that they’re viewing their current situation through.

Because in the end, Yuuji’s still human, and Satoru’s long forgotten what that feels like.

But, even if the mind forgets, the body still remembers—it’s something that Satoru knows now to be true, especially as he lets some muscle memory from years ago take over as he fucks into Yuuji’s tight heat, losing himself when Yuuji’s soft, amber eyes finally flutter open again, looking into Satoru’s with adoration and love—

It sends a pang of longing through his heart (or what’s left of it), and for some reason, his vampire side roars to life in a fit of fury, overtaken by some sort of raw, feral emotion, and something inside him suddenly snaps.

“Hngh—agh—! S-Sensei, n-no—”

Yuuji cries out as Satoru’s fangs sink into his calf, biting hard, not even caring to drink the blood that leaks out. 

“A-Agh—if you bite again, then I’m gonna—a-ah—!”  

A desperate wail is ripped from Yuuji’s throat as Satoru begins to fuck into him, setting a burtally rough pace, completely different from the soft, gentle thrusts he was giving Yuuji earlier.

Satoru doesn’t know why he’s lost control, it’s like the vampire in him has taken over completely—he feels as if he’s watching himself from another person’s perspective as he watches himself slide his hand through the bloody mess on Yuuji’s calf, before smearing it all over his body.

“Hngh—ah—s-sensei—!” 

He curls a hand around Yuuji’s wrist and tugs, grimacing at but also craving more of his sobs as he bites down into the soft skin of Yuuji’s forearm.

“Agh—o-ow, s-sensei—“ 

Again, he doesn’t even drink, just coats his hands with Yuuji’s blood and marks him all over, leaving handprints on his thighs, his hips, his neck, his face, right over his rapidly beating heart—

Satoru can see the exact moment where Yuuji’s mind becomes clouded with the effects of the venom again, can see it in the way his bright, hazel eyes glaze over and become misty with lust instead.

“G-Gojo-sensei—“ Yuuji rasps, his voice dripping with need as he places a shaky hand atop of Satoru’s, lacing their fingers together, a connection formed using Yuuji’s blood. 

“S-Sensei, please…take me...”

Satoru’s vampire side seethes at their emotional display, and Satoru swallows and grips into Yuuji’s hand tightly as he begins fucking into Yuuji even harder, ignoring the absolutely bloody mess they’re making of the bed as well as their bodies.

“A-Ah—ah—s-sensei, s-so deep,” Yuuji moans, his voice turning desperate and pupils dilating from the effects of Satoru’s venom once more. “O-Oh, g-god—y-yes—harder—more— ”

“F-Fuck, Yuuji—“ Satoru grunts, hands gripping into Yuuji’s hips to lift Yuuji’s lower body off the bed. He pulls his cock out until just the tip is inside Yuuji, before slamming it back in, over and over. 

Satoru continues fucking wildly into Yuuji’s tight heat, can’t control the loud, animalistic snarls that are leaving his mouth as he fails to tamper down his vampiric instincts, and he’s fueled to go even faster with each wet slap of Yuuji’s ass against his hips. 

“S-Sens—G-Gojo-sensei—ah—ah—“ Yuuji moans, his eyes going hazy as Satoru’s venom clouds his senses, “Fill me up, p-please—o-oh—a-ah—mmn—“

“Look at you, Yuuji,” Satoru groans, staring down at him with wild, feral eyes, watching as Yuuji’s body jolts violently with each brutal thrust of his cock. “You’re so drunk off of me—off my venom, off my cock—“

“Y-Yes—hngh, I-I’m yours, sensei—“ Yuuji sobs, his moans growing higher and higher pitched until he’s moaning deliriously, voice breaking into a silent scream when Satoru gives him a particularly rough and deep thrust to the point where Yuuji’s body lifts off the bed.

“Mmmnn—agh—“ Yuuji cries out as Satoru continues slamming in deeply with his brutal thrusts, grinding the head of his cock against Yuuji’s prostate, chasing that hot, white pleasure, fucking into Yuuji as if he were disposable—

“Hngh—s-sensei, I’m gonna—a-ah —AH— “ Yuuji keens, arching up and wrapping his arms around Satoru’s back as he comes, his nails scratching deep, red lines down—

“F-Fuck—” Satoru can’t help the moan that slips at the feeling of Yuuji’s clenching and unclenching walls around him, the almost painful warmth of Yuuji’s fluttering insides, clinging to his cock, like he was made to be inside of him, like they were molding together—

“Yuuji—Yuuji— ” 

Satoru’s vision goes white as he comes, his body trembling as he empties himself inside Yuuji, and he fists a hand into Yuuji’s nape to crash their lips together in a rough, bloody kiss. 

“You’re mine, until the end of time,” Satoru snarls in between the slide of their mouth and tongues, “Even if you die, I’ll bring you back—gonna make you mine forever, as a vampire—“

“Y-Yes—s-sensei, I, I want to,” Yuuji whimpers, and before Satoru knows it, he’s hard, again, his arousal coming back even more intense than before, and he pushes Yuuji back into the bed, looking down with crazed, feral eyes.

His vampire side is acting up inside of him again, but instead of fury, this time it’s growing possessive, almost sentimental, reluctant but also pushing Satoru to press closer to Yuuji—

“S-Sensei—“ Yuuji swallows, eyes growing half-lidded as Satoru parts those smooth, sun-kissed thighs and lines his cock up with Yuuji’s twitching hole again, “I-Inside me, p-please—I wanna feel you—“

“Anything for you, Yuuji,” Satoru purrs, and slides into that tight, beautiful heat again in one fluid motion.

They continue fucking until Satoru’s venom fizzles out inside Yuuji—some rounds at a slow, tender pace, some more desperate and heated. 

Later, when they’re both sated, and Yuuji’s truly, truly cooled down, his eyes fluttering shut as fatigue finally takes over, Satoru allows his mind to wander.

Initially, Satoru figured that their soft, tender, intimacy presented itself to his vampiric instincts as a sign of weakness. Of fear.

Of being more human. 

It lashed out, wanting to drag Yuuji down, wanting to dirty and defile and ruin all the bright, brimming goodness inside of him 

But then...

“I know what this is now,” Satoru realizes, caressing the apple of Yuuji’s cheek with the back of his hand. “My vampire side...it’s never acted up like this before…who would’ve known...”

Who would’ve known that after taking Yuuji’s blood—his innocence— that Yuuji’s fondness for Satoru only increased, to the point that even Satoru’s vampire self became powerless to his unconditional affections. 

He chuckles, because, ironically, it now wants Yuuji as his mate.

It’s not something that’s possible at the moment, with Sukuna’s powers making Yuuji immune to any and all types of vampire venom, but...it’s something Satoru will figure out later.

He smiles to himself as he slowly mouths over all the blood and teeth marks he’d left, making sure to lick every inch of Yuuji’s beautiful skin clean.

With time, the bruises and bites will fade, but Satoru will renew them each time he feeds.

One way, or another, Yuuji will become his, for all of eternity.
