Chains Of Love

Summary:

When Tzuyu breaks up with her out of nowhere, Sana realizes how tightly she had been bound.

Vampire AU.

Notes:

In this Vampire AU, vampires and humans can form chosen bonds. A vampire may select a human partner and build a relationship that is both emotional and physical. Feeding and love often intertwine. The bond is mutual rather than purely predatory. Or at least, that is what they tell themselves.

(See the end of the work for more notes.)

Work Text:

Sana had been in Tzuyu’s room before.

 

Once. At least. 

 

Back then, she had asked to use the bathroom, offering a quiet excuse about needing a moment alone. Tzuyu had let her go without a second thought, unaware of what she truly was.

 

That night, Sana had moved slowly, as though any sudden gesture might disturb something sacred. Her fingers brushed the edge of the bed first, tracing the seam of the mattress, pressing lightly into the place where Tzuyu’s body had rested moments before.

 

Even then, she had known she was acting a little too unhinged over just a human. Smoothing her palm across the sheets, tracing the faint crease left behind by sleep. Lifting the shirt abandoned on the chair and pressing it to her face, breathing in what little scent remained. All those things were kind of obsessive.

 

That memory felt distant, almost faded. Strange, for someone to whom time meant very little.



Tonight, she was here again.

 

Uninvited.

 

All because the past few hours had been unbearable. Every minute since she left had stretched painfully, refusing to dull, unwilling to disappear…

 

It was ridiculous to think about it.

 

After centuries, she should have been immune to that kind of impatience.

 

But she wasn’t.

 

And Tzuyu had left her no other choice.

 

Thus, if the door would not open, then the window would.

 

Sana knew exactly what that made her.

 

A dark predatory creature slipping into a bedroom uninvited.

 

Well.

 

That part, at least, was accurate.

 

“I want to break up…”

 

The words echoed in her head, over and over, like a game designed to hurt her.

 

Humans did not usually break up with her, and the words sounded almost misplaced coming from Tzuyu’s mouth, because for centuries she had been the one deciding when things ended. She collected them, kept them close for as long as they entertained her, and discarded them when boredom set in. They rarely left first.

 

When she met this pretty girl months ago, she had assumed it would follow the same pattern, just another diversion to pass the time that stretched endlessly before her. Eternity had a way of making even the most vivid things fade into monotony, and she had believed Tzuyu would be no exception.

 

But she had miscalculated.

 

She liked this girl more than she had intended to, more than was safe, to the point that she could not even tolerate the thought of another vampire noticing her, wanting her, tasting her blood. Because they would. That was what her kind did. They took what they desired and called it a day.

 

She knew them because she knew herself.

 

And the idea of leaving Tzuyu behind was unbearable enough—but the thought of Tzuyu choosing to leave her, of walking away on her own terms, was worse.

 

With those thoughts weighing on her, she remained where she was, watching.

 

The clock signaled it was past midnight by the time she realized how long she had been standing there.

 

Only then did she register the stillness of the moonlight stretching across the floor, climbing the edge of the bed, brushing faintly over Tzuyu’s face. The blanket had slipped slightly, exposing the curve of her shoulder, and her breathing remained slow and even, untouched by the presence hovering in the dark

 

Nevertheless, Sana stepped closer, the restraint she had carried for weeks had thinned to something laughable as she leaned over the bed, hovering above the human, close enough that their breaths mingled.

 

It hurt.

 

For a second she closed her eyes.

 

The scent was stronger this close.

 

So tempting, her fingers lifted slowly, cool against the warmth of Tzuyu’s skin, comijg to rest at her shoulder. From there they moved without hurry, tracing the line of her neck and back again, remembering the shape through touch instead of memory. Eventually, her hand drifted lower, following the curve of her waist as she shifted closer, settling herself around Tzuyu’s hips with intent, hovering above her throat.

 

“I thought I could forget this…”

 

She whispered, lowering herself further, letting the tip of her nose trace the warmth of Tzuyu’s cheek, gliding along the softness of her skin toward her jaw.

 

“But I can’t.” Her thumb pressed lightly against the pulse beneath her skin.

 

Blood tears welled up around her almond-shaped eyes as the tips of her silky, chocolate-colored hair grazed the human’s face. She didn’t want to hurt her. All she had ever wanted to keep her safe—from this curse.

 

As she looked down at that beautiful face resting so innocently beneath her, all the years collapsed into this moment.

 

Tzuyu stirred at the contact, a faint crease forming between her brows as her sleep began to thin.

 

And before Sana could gather the will to disappear, those beautiful eyes opened, seeing her clearly.

 

At that moment, one of her hands rested over Tzuyu’s heart, and she felt it accelerate beneath her palm as awareness settled into that confused gaze.

 

Sana understood the image she must present. Waking to a figure hovering above the bed, fangs visible, blood tears still marking her face—there was nothing gentle about it.

 

Whatever beauty she possessed had no weight against the sight of it.

 

But she did not have the will to leave and allow Tzuyu to dismiss this as a nightmare.

 

So she remained there.

 

Against judgment.

 

In response, Tzuyu did more than stir; she moved abruptly,  rising her hands to press against Sana’s shoulders as she tried to push her away. The confusion in her eyes sharpened into alarm, struggling to sit up.


Before any sound could break the silence of the house, Sana made her choice, and in doing so, crossed the line of force she had sworn not to approach, holding the human
in place, not gently but firmly.  As someone immortal there was no real contest between them. Tzuyu, fully aware of what she was, understood that too, and after a brief struggle she stopped resisting.

 

But surrendering physically did not soften what followed.

 

“What are you doing here?” she asked, her voice steadier than her pulse. “Should I retract my invitation?”

 

All Tzuyu had to do was say the words, and Sana would have no choice but to leave. The same invitation that once allowed her inside could be undone just as easily, and her body would obey without argument, forced to withdraw whether she wanted to or not.


She had only seconds before the decision was made, before she was pushed out of the room.

 

And in those seconds, she found herself grappling with something far more humiliating than physical resistance.

 

Why did this human want her gone?

 

Why was she the one being dismissed?

 

“I can’t stop wanting you and it’s ruining me,” she said quickly, bracketing Tzuyu’s hips with her own as her fingers closed around her wrists.

 

She wasn’t being overtly forceful, but the hold left no doubt that she wasn’t moving.

 

Still, all she received in return was that tired, almost indifferent look as their noses brushed in the tight space between them.

 

“Wanting me,” Tzuyu asked quietly, “or my blood?”

 

The question was brutal in its clarity.

 

Sana felt something in her falter, and her grip loosened slightly as dark red tears streamed down her face, spotting the human’s cheek with warmth.

 

Vampire tears were not beautiful, and she was painfully aware of that. It wasn’t the first time Tzuyu had seen her like this.

 

Yet it wasn’t  as if Tzuyu herself hadn’t caused them before, and that made the shame settle deeper than usual.

 

“You really think that’s it?” Sana said, quieter now as she wiped the tears away with the back of her hand, dragging the red across her cheekbones without caring how it looked.

 

“For someone who’s been alive that long… you take things very personally.” Tzuyu said, earning an indignant look from the vampire. After a second, she added, quieter, “It doesn’t matter. It’s done.”

 

“Why?” Sana insisted, her hands moving restlessly along Tzuyu’s neck and jaw, brushing her cheek as if touch alone could anchor her.

 

Anyone else in Tzuyu’s position might have withdrawn the invitation by now. A vampire pressed this close, clinging instead of retreating, was rarely a safe presence. It often ended with someone drained.

 

But Tzuyu did not look afraid of her blood-streaked ex.

 

Instead, she let her palm settle against Sana’s lower back and slowly draw upward, her fingers threading into the hair at the nape of her neck. Their noses touched. Their mouths hovered a breath apart.

 

“We both know how this ends,” Tzuyu murmured. “I’ll age. You won’t. And you don’t want me like you.”

 

“Why would I?” Sana cut in, almost sharply. “I love you as you are.”

 

As she spoke, her touch turned more deliberate, thumbs brushing over Tzuyu’s lips, framing her face, smoothing her cheeks, pushing loose strands of hair aside. There was something obsessive in the way she handled her, protective and possessive all at once, as though preserving her from something—perhaps even from herself.

 

“You’re meant to stay like this, precious, innocent,” she said more quietly. “You shouldn’t lose that.”

 

This time, it was Tzuyu who answered with a look. She rolled her eyes faintly and turned her face to the side, defiant in the smallest of ways.

 

The movement only drew Sana closer.

 

Her mouth followed the line of Tzuyu’s throat, placing slow, unhurried kisses along the visible tendon there, lips brushing warm skin.

 

Tzuyu kept her composure despite the sensation, her breathing controlled, her gaze fixed somewhere past Sana’s shoulder.

 

“Not so innocent when you’re the one hovering like that,” she replied at last, her tone steady. “Or is this just about feeding?”

 

Sana exhaled softly, the sound almost tender, almost at odds with what she was.

 

“You know it’s not that simple,” she said, her mouth still close to Tzuyu’s throat. “If it were only hunger, I wouldn’t be here.”

 

Her fingers traced absent patterns along Tzuyu’s waist as she spoke.

 

And she wasn’t lying.

 

When a bond ran that deep, it stopped being casual. It wasn’t something you did just because you were thirsty. In her kind, thirst and desire were often tied together. Feeding and sex—sometimes one, sometimes both—were treated the same when it involved the person a vampire chose to be with.

 

And that was what made the thought unbearable.

 

Not just Tzuyu with another vampire—

 

But Tzuyu letting someone else take from her like that.

 

“Then drink,” Tzuyu said at last, her tone almost careless, though the defiance beneath it was obvious.

 

Sana noticed. That was exactly why she kept her fangs where they were despite the ache pressing against her gums.

 

“I should,” she replied, her voice tightening as her hand closed in Tzuyu’s shirt, curling into the fabric. “I really should.”

 

“Then do it,” Tzuyu replied, and this time she turned her head back toward her.

 

Their lips brushed in the movement, breath mingling in the narrow space between them.

 

Sana’s grip faltered for a second.

 

“You’re testing me,” she said, quieter now.

 

No reply came from Tzuyu, and they remained suspended in that narrow space longer than either of them had intended.



That distance, despite how little there was, felt unbearable.

 

She hated how right Tzuyu was. For a creature who had endured hunger, exile, and the slow erosion of time itself, she was inexplicably fragile when it came to this. She could endure all those. But not this—this constant unraveling over a single human.

 

Was this the price for refusing to turn her?

 

Was this what she earned for preserving the one thing that would eventually take her away?

 

Another dark tear slipped free and traced the curve of her cheek before falling against Tzuyu’s lips.

 

Its sight left her voiceless for a moment before she straightened abruptly, pulling back as she no longer trusted herself to speak. She turned toward the window she had come through, putting distance between them before she could undo everything she had just held together.

 

Obviously, coming here had been a mistake. She couldn’t—wouldn’t—give Tzuyu something so irreversible. Immortality was not the gift humans imagined.

 

If she could spare her from that, from the isolation and the endlessness, she would.

 

Even if it meant stepping away.

 

“Sana.”

 

The sound of her name in that voice was was enough to make her pause. She always did when it was her calling. Tzuyu knew that, which was why the human didn’t rush. Instead, She rose and crossed the room at an unhurried pace, closing the distance between them.

 

The action tempted her to turn; however, she resisted the pull and, instead of facing the human, she kept her hand resting against the window frame as she waited.

 

Eventually, Tzuyu closed the distance herself, reaching up to cup her face and guiding her gently to turn. For a brief second their eyes met, and Sana almost spoke—almost said something reckless—but the words never formed, because Tzuyu lowered herself to her height and pressed her warm lips against the damp skin of her cheek where the blood from her tears still lingered.

 

For a moment, the contact could have stolen her breath if air was needed.

 

Tzuyu rarely initiated touch, and precisely for that reason it carried weight when she did. This time was no exception. As her tongue moved slowly along Sana’s cheek, wiping away the dark stain, the gesture left no room for misinterpretation.

 

“I hate seeing you like that.”

 

The taller girl said, pulling her closer as she whispered.

 

“You’re the one who keeps putting me there,” Sana murmured, though the edge in her voice failed to carry the accusation she intended, her hands tightening instinctively in her lover’s pajamas as if the fabric were the only thing keeping her from unraveling again.

 

Instead of answering, Tzuyu persisted with her task, brushing her tongue carefully along the corner of Sana’s eye and gathering the last dark trace that lingered against her skin, as though removing it were more important than any reply she could have given.

 

Only when there was no visible trace left of what had just passed between them did their mouths finally meet. At first it was nothing more than a brush—an exchange of breath, a quiet recognition—almost restrained, almost careful. But neither of them had the patience to linger in half-measures, and the kiss deepened naturally, their lips pressing together with a familiarity that made hesitation feel unnecessary.

 

Sana could taste the faint trace of her own tears on Tzuyu’s tongue, and she answered by sliding hers against it, slow and intentional, until the rhythm between them erased the space that had separated them moments before. Their mouths moved in sync, seamless, until it became impossible to tell who had leaned in further or who had yielded first.

 

As desire sharpened, Sana’s fangs emerged as they always did when aroused, brushing lightly along the inner curve of Tzuyu’s lips. They had been together long enough to know exactly how to move without drawing blood—how to angle a kiss, how to press without piercing—unless one of them intended otherwise.

 

At times, Sana let the edge of a fang graze just enough to remind her of what she was, but not enough to harm. Meanwhile, Tzuyu’s hand slid higher along her neck, holding her there, firm and unafraid.

 

They remained locked together longer than either should have, but eventually breath demanded its place. Tzuyu’s pulse had begun to quicken beneath Sana’s palm, a  reminder of the difference between them, and so she pulled back before it passed the point of safety.

 

Her fangs were still visible when she pulled back. Some humans, even the ones willing to offer their necks without protest, preferred not to look at the very thing that would pierce their skin. The sight made it real in a way they couldn’t romanticize, she supposed. But that had never been Tzuyu’s case. If anything, her eyes settled there with a kind of curiosity that bordered on want.

 

It was no surprise, then, that after a few breaths she leaned in again and resumed their kissing, as though the interruption had only intensified what was already there.

 

In reward, Sana kissed her back, deeper this time, her arms sliding around her neck before lifting herself and wrapping her legs around Tzuyu’s waist with familiarity.

 

She had always favored taller partners since her creation; it was a personal indulgence she never denied. Being held like that—suspended and yet in control—satisfied something in her that had nothing to do with blood.

 

And having a tall girl who could meet her intensity without retreating, who could look composed one moment and melt the next when she pressed just enough, was a pleasure she embraced fully.

 

With those thoughts, she whispered near Tzuyu’s ear “Bed.”

 

They met the mattress together, the movement seamless, mouths still joined as hands worked at fabric, clothing loosening and falling aside without a word.

 

“Good girl,” she murmured, letting the human remain poised over her a moment longer, savoring the steady pressure of a strong thigh nestled between her legs.

 

The praise drew a hungry kiss in return—almost sharp enough to split Tzuyu’s mouth—but Sana eased away at the last second. She had no desire to damage what she cherished, and those lips were far too beautiful to mark.

 

Instead, she focused on unclasping the bra, guiding the taller girl’s bare chest flush against her own.

 

A quiet breath escaped from her throat as heat flooded her senses. Night-born as she was, warmth like that felt intoxicating. Humans carried it so effortlessly in their skin, in their pulse. She could drink from it, feed from it… claim it. And with her beloved, she could have everything at once.

 

As their kissing dragged on, the noise between them grew unabashed—wet mouths meeting, breath spilling into breath—while loose strands of hair slid across their cheeks and lips, snagging briefly between teeth before being pushed aside, careless, consumed.

 

Gradually, Tzuyu’s mouth left her lips and began to wander, tracing a slow, deliberate path over her jaw and down the length of her throat. She lingered there, teeth pressing into the pale curve of her neck, drawing the skin between them and sucking hard enough to leave proof behind.

 

Sometimes they blurred the lines like this, she’d let Tzuyu take that  role. And perhaps Sana indulged her a little too much in that fantasy until a small disagreement spiraled into a breakup neither of them had truly wanted.

 

She didn’t find that amusing.

 

So she allowed it only for a moment  before her fingers slid into Tzuyu’s hair in a quiet but firm correction, guiding her down the center of her body, away from her neck. Tzuyu’s mouth dragged over her collarbones instead, nibbling there before moving lower. When she reached her breast, she embraced one nipple with her lips, sucking more carefully this time.

 

Sana arched, a broken sound spilling from her throat as she offered her chest more openly, fingers sliding into the human’s hair.

 

The warmth of her tongue circling the areola made her dizzy.

 

She burned everywhere Tzuyu touched. Her nails scraped lightly along the back of the girl’s neck, not to hurt, just to keep her there.

 

“So gentle for me,” Sana murmured, voice softer now, threaded with praise. “But don’t wander too far from me…”

 

Tzuyu hummed against her, and the vibration rolled straight through Sana’s chest, pulling another helpless moan from her as she tipped her head back. For a second she could almost lose herself, but the ache behind her fangs kept pulsing, reminding her that the pleasure blooming in her chest wasn’t simple. Thirst and desire had braided themselves too tightly to separate.

 

When the human pulled another long suck from her nipple, leaving it red and tender between her lips, Sana’s fingers tightened in her hair — not to push her away, but to claim control. In one smooth motion she shifted their weight, rolling them over without breaking contact, rising above her with effortless strength.

 

The mattress dipped beneath Tzuyu’s back as Sana settled over her hips, her thighs bracketing the human’s waist.

 

Their mouths met again, but only for a fleeting second before Sana shifted, trailing to the side as if she couldn’t stay still. She caught the corner of Tzuyu’s lips between her own, sucking there gently before dragging lower, over the sharp line of her jaw and down to her neck.

 

The pulse beneath that soft skin was impossible to ignore.

 

It throbbed steadily, warm and alive, and the sound of it filled her head until she nearly gasped. The scent alone was enough to make her dizzy. Sweet. Inviting. Far too tempting.

 

How embarrassing.

 

So many years walking this earth, mastering restraint, perfecting control—and here she was trembling like some fledgling who had never tasted blood before.

 

Inviting her to do just that, Tzuyu tilted her head to the side and slid her fingers into her hair, pressing her closer until Sana’s mouth hovered at the strongest point of her pulse.

 

And Sana went still.

 

For a moment she did nothing—just breathed against the exposed skin, feeling the rise and fall of Tzuyu’s chest beneath her hands.

 

Her fingers tightened instinctively, grounding herself.

 

The invitation had been clear.

 

And to honor it, Sana lowered her mouth fully to the offered skin, letting her tongue drag slowly from the base of Tzuyu’s throat up toward her jawline, tasting the heat there instead of breaking it.

 

“Why are you hesitating?” The human murmured. Her thumb brushed lightly against Sana’s scalp as she tilted her chin a little higher. “You were so confident a second ago.”

 

”Shhh” Sana let her fingers drift upward until the pads of them brushed Tzuyu’s mouth, pressing lightly against her lower lip as if to quiet her for being too mouthy. She hovered there for a moment, suspended between control and surrender, breathing in the sweetness of warm human skin while her fangs rested delicately against the curve of her throat, as though giving herself one final second to decide whether she would remain gentle or give in to what her body demanded.

 

To test the human, she drew a soft pull first, gathering it between her lips, then pressed down, breaking it slowly, tenderly. The flesh opened beneath her small dainty fangs and blood welled at once—not in a violent rush, but in a soft flow that met her tongue the moment she drew in.

 

It spread warm across her mouth as she swallowed.

 

Tzuyu’s fingers tightened in her hair as it happened, firm but not panicked, and Sana felt the shift beneath her—the quickened rhythm of her lover’s pulse, the rush of adrenaline that always followed the bite. No matter how many times they had done this, the contact never lost its edge.

 

With every heartbeat striking harder against her lips, Sana softened her pull. She took only small mouthfuls, barely drawing more than she needed while Tzuyu’s breathing gradually evened out, slipping her arms around Sana’s waist, allowing her to remain pressed to her skin and continue feeding without resistance.

 

She kept the moment stretched, letting warmth seep into her cold body while the thirst dulled and deepened at once. Relief tangled with craving inside her.

 

It was impossible not to want more.

 

Especially when those soft, breathless gasps kept slipping from her with every subtle shift of Sana’s mouth. Especially when her fangs pressed a fraction deeper into warm flesh—never enough to harm, only enough to feel the delicate give of skin yielding to her.

A quiet tremor rippled through the body beneath her, and another strong pulse throbbed insistently against her tongue—steady, alive, urging her to take more.

 

So sweet. What a precious girl she had, Sana thought. 

 

After a moment, though every instinct in her urged her to stay right where she was, Sana drew her fangs out with the care the moment required. Desire still burned through her, but she held it back; this was only the beginning, and she refused to rush what she intended to savor.

 

The wound closed gently around the absence of her fangs, yet a thin line of blood slipped free, tracing down as their eyes lifted and locked.

 

Sana lifted her hand to wipe the trace away, but Tzuyu was quicker, brushing softly over her lower lip with her thumb and gathering the remaining warmth before it could fall, her touch familiar and intimate, as if cleaning her were simply part of the ritual itself.

 

“Feeling better?” Tzuyu asked softly, her hand rising to cup the back of Sana’s neck and draw her closer.

 

The vampire’s palm rested against her breast, kneading gently as she felt the steady, fervent rhythm beneath—an intimate pulse that never failed to captivate her, no matter how many times she listened to it.

 

Sana gave a small nod before lowering her lips, scattering dark, blood-tinged kisses along warm skin, a low hum vibrating in her throat. Her hands slid down to Tzuyu’s thighs—firm, yet careful—guiding them apart as she continued her slow descent.

 

Tzuyu’s stomach tightened under her mouth, muscle flexing every time Sana’s lips pressed or her teeth grazed lightly. She stayed there longer than she had to, licking over the lines of her abs, feeling them tense and release while her fingers hooked into the waistband of her panties.

 

God. So warm. So alive.

 

If she’d had a heartbeat, it would’ve been racing.

 

Tzuyu arched slowly beneath her, offering more of herself without forcing anything. She never rushed her. She let Sana take what she wanted—let her mouth wander, let her teeth catch softly around her navel, let her breathe her in.

 

Still, the heat further down kept calling to her, and once her mouth reached the human’s sweet flower, she began by peppering its petals with soft, lingering kisses as if she hadn’t already tasted her before.

 

Tzuyu’s fingers tangled tighter in Sana’s hair, gripping at the roots, and that was all the encouragement she needed as she dragged her tongue over the swollen nub, slower at first, then faster—flat, strokes that made it throb harder against her mouth. She let her lips close around it, sucking just enough to draw a broken sound from Tzuyu’s throat before releasing and flicking back over it with quick, teasing.

 

Tzuyu’s moan came out rougher, fuller, her hips shifting as Sana pressed in closer, burying her face between her thighs. She alternated between sharp flicks and deep, messy sucks, letting her tongue circle, press, and tease until Tzuyu’s thighs began to clamp around her head, tightening with every wet, relentless lap of her tongue.

 

However, the human didn’t stop her—didn’t try to guide or rush her.

 

Taking it as trust, as approval, Sana slid one hand slowly up Tzuyu’s body, leaving her mouth where it was. Her fingers trailed over her hip, up the curve of her waist, searching until they found the girls hand resting on her stomach.

 

Their fingers laced together there, pressing palm to palm.

 

Tzuyu squeezed first.

 

Sana held on tighter in return, anchoring herself to her while she continued.

 

Moans thickened the air, blending with the heavy scent of sex. Sana was soaked herself—she had been ever since Tzuyu’s blood first hit her tongue, now tangled with the slick, salty sweetness spreading beneath her mouth.

 

It drove her feral.

 

She shoved her face in harder, nose grinding between Tzuyu’s folds, dragging through the wet heat. Her lips were already slick, chin shining, breath hot as she inhaled her scent like it was something she could live on.

 

She was both thirsty and aroused, the need curling tight in her stomach. After one last slow, deliberate suck to the clit, she dragged her mouth away and shifted lower, to the inside of Tzuyu’s thigh—so close to her sex that the heat of it brushed her lips. And then she bit.

 

The human swallowed a gasp, fingers tensing but never pushing her away. The fangs sank in near the most sensitive place, intimate and dangerous, yet she didn’t interfere. It wasn’t as though Sana hadn’t fed from her before.

 

Despite the bite being filthy in its placement, Sana kept her mouth pressed to the wound, tongue resting over the split skin as the first spill of heat touched her.

 

Only then did she pull. Then deeper and harder, drawing straight from the pulse beating under her lips. The blood came sweet and hot, flooding her mouth in consistent waves.

 

She groaned against Tzuyu’s cunt, pressing her hips into the mattress as she swallowed again, greedy. The mix of blood and sex was overwhelming.

 

She felt dizzy with it, close to fainting despite the fact that she wasn’t even human.

 

Blood bound them too thoroughly. As it slid down her throat, Sana swore she could feel what Tzuyu felt. They had both tasted each other; the connection ran both ways. It was intimate in a way that went beyond sex, beyond hunger.

For a fractured, breathless moment, it felt as though they were no longer two bodies pressed together but a single current running through borrowed flesh—one pulse, one pleasure, one body.

 

A chain forged in blood, wrapped around their souls and threaded quietly through their veins.

The force of it left her shattered and split open, yet somehow whole at the same time. Something inside her cracked, revealing its truest shape.

Immersed in it, a tear of diluted red slipped from the corner of Sana’s eye as a violent wave tore through her. It struck at the exact second Tzuyu reached her own peak—back arching, breath breaking, her body tightening around the overwhelming pull.

 

Sana forced herself to stop sucking. If she didn’t, she wouldn’t stop at all.

 

The moment her mouth left the wound, she lifted her gaze—and the sight of Tzuyu coming apart in front of her, flushed and trembling, dragged her right back under.

 

For a split second, doubt flickered. Had Tzuyu felt it too? Or had the connection existed only inside her own starving mind?

 

She didn’t let herself linger on it. Instead, she leaned down and sealed the wound with her tongue, watching the bleeding stop.

 

Then she lifted herself over her again, bracing on her elbows, searching Tzuyu’s eyes..

 

She looked for any haze, any weakness—any sign she had been too greedy.

 

“Don’t go far from me…” Sana whispered.

 

In answer, those eyes focused on her. The sight leaving her both relieved and satisfied.

 

After all that, an earned quiet followed.

 

Tzuyu’s breathing deepened, soft and even. Sana listened in silence, her cheek resting near her shoulder, her hand spread over her toned stomach, watching the slow rise and fall beneath her palm.

 

The bed sheets were stained with cooling sweat, slick, and blood—faint rust-colored marks near both bites. The dampness along their thighs was mostly Tzuyu’s, as Sana did not answer desire in the same way.

 

Still, what she had felt had been pleasure all the same—just drawn from a different place.

 

“So we’re back together, I guess…” Sana murmured, tracing lazy circles around Tzuyu’s navel with the tip of her index finger.

 

At that, the human shifted onto her side and buried her face against Sana’s neck, avoiding the question entirely—as if the words she’d spoken hours ago no longer carried the same weight.

 

Sana hummed softly, fingers resuming their slow pattern but in the head. “You can’t just hide like that,” she said under her breath, pressing a small kiss into Tzuyu’s hair. “Talk to me.”

 

“I’m tired…” the human replied, voice muffled against her neck.

 

Sana almost smiled.

 

Hiding again, she thought. Behind that shy, harmless act she usually found so endearing—just not now.

 

“You weren’t too tired a minute ago,” she said quietly, not unkindly.

 

Tzuyu shifted but didn’t lift her head. “That’s different.”

 

“Is it?” Sana’s hand slid from her hair to the curve of her shoulder.

 

“You just drank from me,” she reminded her quietly. “More than usual.”

 

Sana paused.

 

…Fair point.

 

“Are you keeping up with your supplements?” she asked after a second.

 

And as practical as it might have sounded, it unsettled her to know she had taken that much from her beloved.

 

Over time, they had found a balance—a careful middle ground when it came to feeding. A point where hunger was eased without leaving Tzuyu drained. But there were moments, like tonight, when she felt herself leaning closer to the edge than she meant to.

 

“You have to eat properly too,” Sana added, softer now. “Don’t pretend you forget.”

 

The concern lingered with her longer than she let show.

 

In response, Tzuyu only gave a quiet hum and shifted higher against her, draping herself fully over Sana as if she could cover her entirely—like a blanket made of warmth and living weight.

 

And while she could allow the subject to rest for tonight, the explanation would have to arrive tomorrow.

 

She only hoped it wasn’t Tzuyu considering replacing her with someone willing to do the job faster than she intended.

 

Or worse, with a human too confident for their own good.

Notes:

Little did TWICE know I walked out of their concert two nights ago with a dangerous little idea. I’ve always wanted to try something like this, and honestly, with this freezing weather, I figured it was time to warm things up a little.

Did you like it?
Should I make a MinaYeon vampire au version?
