She jerks awake with a start, eyelids fluttering as she struggles back into consciousness.
All she sees is light, soft and muted, but with the way her temples are pounding it feels more like a beacon, blinding and brilliant. She shakes her head, a groan escaping her as she tries to regain her bearings.
Where is she?
The last thing she remembers is having lunch with her brother. She hasn’t seen Aether in a while, given their busy schedules—when he asked her whether or not she’d have time for a meal later, naturally she said yes.
Aether. What happened to him? She tries to sit up, her mind fuzzy, and realises with a note of panic that she’s bound to something—she tilts her head and realises that her wrists are tied to a bed frame, and her brother is nowhere to be seen.
Fear grips her, brutal and unyielding. What happened during lunch? She can’t remember a single thing. Is Aether all right? Did someone barge into their home to kidnap them? But surely she would recall such an event. And his friends, his friends wouldn’t just leave this be, right? They must be searching for him—
She hears something rattle, metallic and sharp, and abruptly she shuts her eyes and exhales. She’s still alive, so it implies that she’s needed for something. Perhaps the kidnappers will demand a ransom.
Money isn't a problem. She’s just fearful for Aether. She can’t see him anywhere, and the thought of him alone, panicking over her whereabouts—her chest twists, and she turns her cheek into the mattress.
It’s a little dusty, and she holds back a cough, her eyes burning. From what little she has seen, this room she’s trapped in is in poor condition. The wallpaper is peeling, the ceiling is mottled with mould, and if she listens closely she thinks she can hear the squeaking of rats in the distance.
It makes her feel sick.
The door creaks open, slow and purposeful. Whoever these people are, they are clearly not worried about her escaping. She bites her lip, trying to determine whether or not she should risk a peek, but then she hears the sound of footsteps and promptly decides against that course of action.
“Lumine.” The voice is quiet but familiar, and she perks up, her heart racing. “Are you awake?”
Her eyes fly open at his question, searching for him. Her gaze lands on Aether, standing beside the bed, staring down at her with a furrow in his brow, his arms folded across his chest. “Aether! Where are we?”
Of course, he must have broken free from his kidnappers, and now he’s going to rescue her. He’s always so capable, after all. Despite her situation, she can’t help but feel a flicker of pride.
“From what I know, we’re in an abandoned house, some distance away from town.” He sits on the bed beside her, his gaze raking her up and down. His frown deepens. “Do you remember what happened?”
She shakes her head. “One moment we were chatting, and the next thing I knew I was waking up here.” She tips her head back, eyeing the thick, coarse ropes that have secured her to the rusty bed frame. “It would be nice to get out of these, by the way.”
But Aether doesn’t move to free her, not as she expects. Instead, he leans closer, his braid coiling over her chest, and she flinches at the look in his eyes. Those golden depths are neither warm nor gentle.
She has never seen that calculative expression on his face before, not even when Favonius Corporation approached him and offered him that music deal. Aether is not picky—he’s sweet and earnest, which is why he’s so popular among his fans.
This man hovering over her, something akin to hunger in his eyes—this man, she thinks, is a stranger.
“I was hoping you’d remember a little, at least,” he says, and there’s a cold edge to his voice she’s never heard before. It reeks of danger, sends a shiver down her spine as her wrists flex, instincts telling her to get away. “It would make all this a lot easier.”
“What?” The word catches in the back of her throat, sudden terror leaving her mute. It makes no sense; this is Aether, her twin. He loves her, her older brother who has been looking out for her their entire lives. She has nothing to be afraid of.
Yet, when their gazes meet, she feels a pit yawning open in her belly, ice streaking through her veins as he watches her like a butcher studies a slab of meat. “How do you think you got here?”
His strange behaviour, this room she’s trapped in, how he has yet to make a move to release her despite being right there—it’s beginning to add up, but she refuses to believe it, refuses to think that her brother would ever hurt her. “S-Someone kidnapped us, right? But our friends should know, we’ll be fine—”
“No,” he interrupts, and she quietens, her blood roaring in her ears, heart threatening to leap out of her chest. The smile on his face is anything but kind. “I brought you here.”
The admission threatens to shatter her. She shakes her head, still in denial despite all the evidence that tells her otherwise. “No. Y-You’re lying. The kidnappers are forcing you to do this, right? To lie to me and make me distrust you. But I know you, Aether, you would never do such a thing—”
“You think too highly of me, Lumine.” His hand reaches out, knuckles grazing her cheek, and she tenses, unnerved by the sudden softness in his eyes. Something lurks underneath his gentleness, and it makes the back of her neck prickle. “I’ve been wanting to do this for ages.”
She swallows. This must be an act. Maybe the kidnappers are watching from elsewhere, making sure he doesn’t say anything out of line. In that case, she ought to play along. “What do you mean?”
“I never have you to myself anymore.” He sighs, wistful, fingers sliding further down to brush across her lips. “When I first joined the group, you were always rooting for me. Attending all our concerts, cheering from the audience. And I’m so grateful for that. I don’t know how far I would have gotten without you.”
She blinks, unsure where he’s going with this. “Aether?”
He continues, not acknowledging her interruption. “But then you signed on with Teyvat Group. I’ve told you again and again,” and she flinches at the rage in his voice, at the way his eyes narrow down at her, “I don’t want you to be an idol. I don’t want you dressed in some skimpy outfit, prancing around on stage, allowing men to jack off to photos of you after your concert is over.”
She opens her mouth, unsure if she’s more angry or upset about his sudden outburst, but he barrels on. “But you refused to listen. You became an idol, and not only did you disobey me, but you also no longer made time for me. Me, your brother. When you claimed to love me the most in the world.”
“Aether!” she snaps, frustrated now. It’s hard to believe this is just an act when he seems so vindictive, his eyes blazing with self-righteous anger. “Listen to yourself! You sound ridiculous!”
She’d always known he was unhappy with her decision to become an idol, but she never knew the true extent of his disapproval—when she first told him the news, he’d simply frowned at her, cautioning her against this path. But he didn’t say anything else, and she thought that was the end of it.
Yet here he is, almost nose-to-nose with her, and suddenly she’s painfully aware of how much stronger he is compared to her, how vulnerable she is right now, bound and helpless. When she inhales, she can smell the faint spice of his cologne, a scent that reminds her of home, and she wants to sob.
This is a nightmare. It can’t be real. Aether has never gotten this angry at her before, shouting at her like she’s wronged him terribly when all she has ever done is to follow her dreams—
“Ridiculous?” His words soften, and she shivers once more, the fury in his voice dissipating as quickly as it came. “You think I’m being ridiculous, Lumine?”
Danger seethes between them, the air brimming with tension, and she swallows, frightened by his intensity. She’s never been afraid of Aether before, and the feeling is far from pleasant. “I mean…”
“No, no.” Suddenly, his hand is on the front of her blouse, and she yelps as he rips the thin cotton, pearl buttons shimmering as they ricochet away. “I see your time spent in our industry has taught you how to speak your mind. You’re no longer my sweet, obedient little sister.” He reaches for her bra, and she cries out in horror as he undoes the front clasp, her breasts spilling free from the fabric.
“Aether! Stop!” she shouts, barely able to believe what’s happening. This can’t be real. “We’re siblings! You can’t just do something like this—”
“Shut up,” he growls, and the rage is back, simmering in his voice. It shocks her enough to cut her off, though her eyes sting as he palms her breasts, rolling one nipple between his fingers. “I’ll just have to make you remember who you belong to, Lumine. Not your fans. Not the Teyvat Group. But to me.”
“You can’t…” she repeats, her voice weak as he pulls apart the rest of her blouse, tears welling up in the corners of her eyes while she tries to get through to him. “You can’t do this, you can’t.”
He simply leans in, his blond hair illuminated by the soft light of the room. “Oh, but I can.” His lips curve upwards, his smile cruel. “And since you’re being so cooperative, I’ve prepared a little surprise for you.”
Before she can ask—does she even want to know, at this point?—he sits back up, raising his voice. “You all can come in now!”
She lifts her head too, dreading what he has in store but curious all the same. Maybe Aether is filming a show, and this is how he’s rehearsing. Or maybe this is just an elaborate prank and he’ll admit it was all some grossly exaggerated joke. Or maybe he’s trying to scare her into ending her idol career early.
Anything is preferable to his hands on her bare skin, skimming down her sides, cupping the undersides of her breasts as he grinds against her, a bulge visible through the dark material of his pants.
The door opens, and she stares, breath catching as the rest of his group files in. Xiao, Venti and Kazuha, all three looking extremely confused—then suddenly, they seem to notice her presence, their gazes snapping towards her as Aether lowers his head, his mouth fastening around her nipple.
“Aether?” Venti is the first to break the silence, fidgeting as she sobs, her voice dissipating into the thin air. “What’s going on? And… what are you doing to Lumine?”
Her brother lifts his head, his mouth leaving her with a pop, and she hates how her nipple stiffens, cold without his attention. “Weren’t you all fantasising about fucking my sister the other night? I overheard.”
She doesn’t miss the guilt that flashes across their faces, and her heart sinks. They’re not here to help. “It was just a joke,” Venti says, laughing awkwardly, though his eyes linger a little too long on her open shirt. “We didn’t mean that, not really…”
“Oh?” Aether turns, swinging his legs off the bed, and her body bounces as he jumps to his feet. Kazuha glances at her, this time with keen interest, and she turns away. “I was going to let you three fulfil your needs, but if it’s just a joke—”
“Wait, what? Really?” Venti doesn’t need further prompting to approach, stepping around Aether towards the bed. “You’re going to let us fuck your sister?”
She blinks up at Venti, the tears she’s been suppressing threatening to overflow. Her eyes sting. “Venti, I didn’t agree to this, don’t listen to him—”
“Lumine needs to remember,” Aether interrupts, gliding back over. She freezes, biting her tongue as fear ripples through her, rendering her speechless. “She’s forgotten how cruel this industry is. But that is my fault for indulging her.” He sweeps over her bangs, pushing them away from her face. “I believe it’s time to remind her why it doesn’t pay to become an idol.”
“You want us to rape your sister?” Kazuha asks. His voice is calm, disaffected, and she flinches, glancing up at him—Kazuha doesn’t even look at her, his gaze trained entirely on Aether.
She’s always thought of him as the kindest among their group, even kinder than Aether, who complains about his fans to her when he’s back from a concert or tour—Kazuha is always ready with a smile, ready to sign autographs or do handshakes or provide whatever fanservice his ardent supporters desire.
Even the other two, Xiao and Venti, unanimously agree that Kazuha is by far the most gentlemanly among them during interviews. So why is he looking at her this way? Like she’s not a victim, tied to a bed by her own flesh-and-blood, on the verge of violation?
His eyes remind her of garnets, beautiful but hard, and so cold that when he glances at her, she shivers.
“Well, I don’t want to use the word rape. I’m sure she wants it too.” Aether looks over his shoulder at her, his golden eyes just as frigid. “I’ve seen the adoring way she looks at us. This must be an honour.”
No, that’s not true. While she acknowledges the attractiveness of their idol group, never has she wanted to go through something like this. Never has she dreamt about being raped by her brother’s friends. “I—”
Aether doesn’t let her finish, his hand moving down from her forehead to clamp over her mouth. “Now, I don’t want to hear anything more out of you, not after all the pains I took to arrange this. Did you think it was easy, Lumine? Finding this abandoned house, sorting out our schedules, clearing leave with both our manager and yours? You need to appreciate your brother more, you know?”
This man is a stranger. He isn’t the Aether she knows. Her twin would never do this to her, never, never—she chokes as his grip on her face tightens, threatening to cut off her airflow. “Do you understand?”
She nods, just the tiniest movement of her head, and he lets go, satisfaction sharp in his smile. “Good.” He slides his fingers down her hair as she bites back a sob, and then he turns to face the other three. “I have a few rules if we’re going to do this.”
“What rules?” Kazuha asks, still the calmest and most relaxed among them. Venti looks uneasy, while Xiao is his usual impassive self, his gaze flitting between her and the ceiling.
“Number one, I’ll be the first to fuck her,” Aether says, matter-of-fact, and her head jerks up, eyes going wide with disbelief at how nonchalant he sounds. “Number two, none of us say anything to anyone. Or believe me, there will be consequences. And number three…” He thinks for a moment, then shrugs, his smile turning soft and sweet, the kind of smile he normally reserves for his fans. “Huh, that’s about it.”
Venti raises a hand, and Aether nods. “What if we don’t want to participate?” he asks, his gaze slanting towards Xiao, who’s still looking away from her, a furrow in his brow.
“Rule number two still applies.” Aether shrugs again. “Look, you’re not going to have a second chance, but I won’t let anyone leave until we’re done, so if you want to just sit there and watch—”
“Ah, no,” Venti interrupts, a look of regret crossing his face. She stares at him, pleading silently with her eyes, but he simply shakes his head, pointedly turning away. “I never said I didn’t want her.”
Xiao is her only hope left, but he stays silent, arms folded across his chest, fingers drumming erratically against his upper arm. “Well, I’m fine with the terms. What about you guys?” Kazuha asks.
Venti shrugs, and Xiao sighs, but neither puts up any resistance. “Mm, since we’re all in agreement, then feel free to do whatever you want,” Aether says, his voice light and airy.
There is nothing she can do, so she closes her eyes and dreams that she is anywhere but here.
Aether is inside her, and she feels like dying.
She has given up on screaming. Aether is stronger than her, and with the threat of his shirt stuffed inside her mouth there isn’t really any point in making her voice hoarse—and besides, as her brother has whispered in her ear, they’re all alone.
No matter how loudly she cries for help, no one is coming to save her. He has placed her phone beside her, mocking her with its proximity, and for the past hour she’s been trapped here not once has her phone lit up. Paimon seems to be taking her leave request seriously.
For once, she wishes that her manager would be her usual self, oblivious and determined, checking up on Lumine even when she begs her to give her some space. But she knows all too well how charismatic Aether can be—he probably had little trouble convincing Paimon to give them quality sibling time.
She isn’t sure what’s worse, the fact that Aether is fucking her or that his friends are watching, all of them noticeably aroused even if their faces don’t show it. She can see the tents in their pants, how they grip the mattress as they hover over her, watching her brother fuck her senseless, and she wants to cry.
She trusted them. She believed they would help her, believed they were good people, but all Aether had to do was to promise them her and suddenly, their principles flew right out of the window.
Aether is groping her breasts, her skirt and panties discarded on the floor as his free hand rubs between them, flicking over her clit while he murmurs words of praise to her, his lips grazing her throat.
He smells like spice and cologne. Like home. And it makes her sick. She looks up at the ceiling, a single tear sliding down her cheek towards the mattress as he thrusts in, slow and languid, forcing her to feel every inch of his cock.
The worst part is that she doesn’t fully hate it. She did, in the beginning. When he forced her legs open and yanked her underwear down, exposing her sex. When he kissed her in a way siblings shouldn’t, all tongue and want and filth—when he dropped to her chest, sucking her nipple between his teeth as he ground his clothed cock against her bare core, the rough material of his pants making her wince.
She didn’t enjoy any of that. But she feels the stares of his friends, feels the way he clutches her, fingers digging into her flesh, her name falling reverent from his lips, and some sick, twisted instinct within her responds, makes her gasp as he spreads her open, as he curls his fingers inside her, coaxing her arousal.
“You’re so beautiful tied up like this,” he murmurs, his hand pressing onto her thigh as he fucks her, hips cradled between her legs. “See, that’s why I have to protect you. Keep you safe from all those filthy men who dare to dream about touching you.”
Her gaze flicks towards Venti and Kazuha, who are standing right next to her, staring in fascination while she’s raped by her brother. Aether notices. “Oh, they’re fine. We share most things.”
“It’s how we stay close,” Kazuha chimes in, and she shivers as he leans in, eyes hungry. His resemblance to Aether is uncanny—it’s not the first time she’s noticed it, but in this context, while Aether is sheathing himself within her, his appearance is frightening. “Just one more thing to add to our list, I suppose.”
“You need to return my jacket. I’ve been trying to get it back for weeks,” Aether says, casual as he slides back, the tip of his cock almost out of her. Hope rises in her chest—maybe he wants to stop, maybe he’s going to spare her further torment—but the feeling crumbles as he thrusts back in, this time fierce enough to send her skittering across the mattress. “Why don’t you just buy the damn thing yourself?”
“It’s not on sale anymore,” Kazuha says, and the two of them continue this back-and-forth while she lies there, defeated, trying to shut out the sounds of their conversation. It’s too normal. They’re treating this so normally, like they’re not out in the middle of nowhere, forcing themselves upon her.
She feels something touch her cheek, and instinctively she turns, meeting Venti’s aqua eyes. At least he looks worried if nothing else. “Poor thing, being tied to the bed like this. You should let her go.”
Aether considers, his hands gripping her hips as his pace picks up, his cock hard and throbbing, making her squirm. “Yeah, sure, why not? It’s not like she’s going to run away.”
Venti nods, undoing the bindings around her wrists, but even when they fall from the ropes she remains still, not bothering to struggle. What’s the point? She’s not going to get free, anyway. Not when it’s them against her, not with Kazuha staring at her with just as much hunger as her brother.
“Lumine, Lumine,” Aether croons, falling forward as his fingers slip between hers. She lets him hold her, too tired to put up any fight—it’s easier, she thinks. To just fall and pretend nothing is wrong. “I’m going to—you’re so tight,” he groans, nuzzling into her shoulder.
He feels good when he thrusts inside her. She knows it shouldn’t, that she ought to be disgusted, that it is terrible that she’s being made to suffer like this—but if she has to be honest, it’s beginning to feel less like sin and more like something she wants, the pleasure humming low and insistent in her belly.
Aether is a good lover. She isn’t sure where he learnt all this—she can count the number of partners he’s had on one hand, maybe two if she includes his middle school conquests—but he’s confident and bold, and he knows exactly how to please. She can’t help but arch into his touch whenever he shifts his focus away from her cunt, fingers toying with her nipples, ghosting down her sides.
When his hand wraps around her throat, squeezing, pleasure whips through her, so sudden that it feels closer to pain, and she keens, gasping for air as his grip tightens. He’s crushing her, and she’s trying her best to stay conscious, his face firmly in her line of sight, but her head is starting to spin and everything feels so… floaty. Like a dream. And she’s desperate to believe that this is nothing but a dream.
“I don’t want to wait anymore,” Kazuha suddenly declares, and she blinks hazily at him as he steps over, his cock fully erect as it pushes out between his zipper. Aether looks like he wants to say something, but Kazuha grins. “This isn’t fucking her, is it? You can’t complain.”
“Fine,” Aether grumbles, and then Kazuha is yanking her hand up, forcing her fingers to wrap around his shaft.
“Stroke,” he hisses, his voice turned low and dangerous, and panicking a little she obeys, sliding up and down as she strives to pleasure his cock. Kazuha sighs, his eyelids fluttering as he pushes against her, and an unwanted flicker of pride burns in her chest, telling her that she did good, that she pleased him just the way he wanted her to.
“Oh, no. That’s unfair.” Venti pouts, stepping closer too. His cock is up in her face, and she stares at it, a little surprised by its size—he’s the tiniest among the four, and she thought he would be on the smaller side, but instead, Venti is thick, his cock erect and veiny as he reaches for her wrist. “I want that too!”
So, obediently, she gets to work on him, both her hands moving as they groan in unison, bucking their hips against her. Aether is still fucking her; she can hear the distinct sounds of sex filling the room, and it makes her burn. She can’t tell whether it’s from pleasure or shame.
Xiao is the only one who has yet to say or do anything. He’s standing a little distance away from the trio, his expression impossible to read—she meets his gaze, another tear rolling down her cheek though this time, it’s not because of Aether—and he shakes his head, averts his face so that he’s looking at the floor.
She doesn’t know what that’s supposed to mean. Is he ashamed on her behalf? Does he disagree with what his fellow idols are doing? But if he does, why doesn't he say something? Why did he just leave her to her fate, content to watch her being taken against her will?
Just then, Aether leans down, his hands grabbing her thighs and pushing her legs up so that her knees rest on her shoulders. “Archons, Lumine,” he moans, voice pitched high and breathless, “I-I’m going to come, fuck—”
She inhales, frightened enough by his sudden claim that her voice bubbles up her throat, the first thing she’s said since he entered her. “No, you can’t!” she cries, her hands going still. “Don’t come, please, it’s not safe, it’s not safe—”
“Not safe?” he rasps, leaning in so that his forehead drops against hers; all the shock and horror she has been suppressing shatters, sending her reeling as she lets go of Kazuha and Venti. Her hands fly up, her palms pressed flat on Aether’s shoulders, trying to push him off. He doesn’t budge. “Good.”
He speeds up, ignoring her pleas, and when she starts to hit him, tears flowing freely down her face, he simply leans down to kiss her, swallowing her cries as he pounds furiously into her sex. She’s dripping by now, and she hates it, hates how her body responds to his cock, hates how she clenches around him, as though trying to coax his seed out—
“Fuck, I’m coming,” Aether groans, and then he stops, shoving in till the hilt, his whole body shuddering as he spills. She’s crying, breath hitching as his cock twitches inside her; when he leans down to kiss her again she doesn’t resist, broken as she is by what her brother did. By what she has allowed.
Her period comes like clockwork. She knows when she is fertile, she knows when she is not. And, with Aether’s cock still buried deep inside her, she's terrified.
“Is it my turn yet?” Kazuha tuts, and Aether parts from her, turning towards him with a roll of his eyes—he pulls out, but before his seed can even begin to trickle out Kazuha has taken his place, sliding inside her in one smooth motion. A moan escapes her, and she turns her head into the mattress, burning with shame.
This shouldn’t feel good. It shouldn’t, but the thought of someone else fucking her brother’s seed into her sends a flicker of unwanted heat straight to her core. Kazuha grips her wrists, yanking them over her head in one hand as the other pinches her nipple, and she arches into his touch, desperate to stop thinking. To stop hurting.
She’s tired of struggling. Maybe it’d be easier to go with the flow. Let them use her body however much they want and drag herself away once it’s all over. She lacks the energy to convince herself otherwise.
In the distance, she thinks she hears her brother’s voice, but she can’t make out what he’s saying. Not that it matters, anyway. It’s not going to help her escape—but then Venti makes way, and she sees Xiao hesitating beside her, his amber eyes trained on her face.
“I’m sorry,” he says, voice barely audible over the sounds of flesh meeting flesh. Kazuha is not as gentle as her brother, taking her hard and fast and vicious—he slams into her cunt and her toes curl, a reflex. “You deserve better than this.”
She opens her mouth, but all she can do is moan, her voice breathless as Kazuha kisses down her chest, taking an abused nipple into his mouth. Her skin feels so tender, the space between her thighs sore; she wonders how much more of this she can take before her mind fragments completely.
“Stop acting all noble,” Kazuha scoffs, raising an eyebrow as he drops his fingers to her clit, eliciting a quiet moan. “You want her just as much as the rest of us. If not, you wouldn’t be standing here now.”
Xiao didn’t answer, just staring down at her as her eyelids flutter, broken gasps escaping her. While Kazuha was occupied with Xiao, Venti had stepped in, his mouth trailing across her heaving chest as she whimpered, his tongue swirling around her sensitive nipples.
His hand joins Kazuha’s at her cunt, circling her clit, and she arches into him, pleasure shooting across her face so abruptly that for a second, he believes he’s imagining it—she coils upwards, trapped in the throes of climax, her mouth falling open in a soundless cry.
It’s so inviting, those pretty lips, bitten and red with abuse. He can’t help himself, leaning down to claim her mouth, and when she kisses him back his cock jerks against the mattress, wanting.
“Lumine,” Kazuha gasps, his hips snapping into her, and she moans into Venti, her fingers clenching the mattress underneath. Venti cups her cheek, tongue sliding in to explore her thoroughly, and she lets out the sweetest little sigh, her legs wrapping around Kazuha’s hips as he pounds into her.
He can barely wait for his turn. But he doesn’t rush Kazuha, pulling back from Lumine to study her face, watching the way she unfurls as Kazuha leans forward, biting down into her shoulder.
When Kazuha withdraws, he’s ready, switching over to sheathe himself inside her. Despite having taken two cocks before him, she’s still warm and tight, and he exhales in one long breath as he pushes in until the hilt, giddy from the feel of her.
Lumine trembles as he enters her, her whine almost pitiful, and he reaches out, his knuckles grazing her cheek. “You like this, don’t you?” he asks, waiting for her response—she nods, slow and dreamy, and he bites his lip, reassured.
While he knows what Aether has done, while he knows she’s not exactly willing, reality is easy to ignore when she sounds so sweet, keening for him as he fucks her.
He’d been fantasising about her for ages, ever since he dropped by Aether’s house and saw Lumine for the first time, emerging from her room with a bright smile on her face and a carefree spring in her step. Something about her just drew him in, though he wasn’t sure what. Her effortless beauty? The natural musicality of her voice? Or her smile, so radiant that it outshone even the sun?
Given the chance, he would compose song after song praising her, his muse. He was their group’s composer, and before meeting her he had been trapped in a rut, unable to create anything new—but the day they met, he went home and within a week had rushed out an entire album and demo, declaring it his best piece of work yet.
Even now, that album, inspired by Lumine, is still their best-selling album to date. He’s never admitted his source of inspiration, but now he feels he no longer has to. Not with her underneath him, her hands gripping his shoulders, eyes glazed with pleasure as she whimpers his name.
Xiao takes another step closer, bumping against the bed, and Lumine looks at him, dazed and exquisite. He can’t help but feel a flicker of jealousy, knowing that her attention is no longer upon him, but… well, Aether said to share. And none of them is willing to go up against their leader.
Especially not in a situation like this, not when it involves his sister. They know better than that.
“You’ll get your turn,” Venti promises, and Xiao meets his gaze, conflict still swirling in his eyes. Among the four of them, Xiao is the most reticent, and after today Venti admits he probably has the strongest moral compass.
But even the most principled people might fall someday, and Xiao is no exception. His gaze flits back to Lumine, and he's pleased to see that she's now staring at him; he thrusts inside her again, a sob escaping him at how good she feels, wrapped tight and plush around his cock.
He would love to see her round with his children, her breasts milky and sweet as he suckles upon them, her expression soft and tender while she strokes his hair… he inhales, hips jerking at the thought, and Lumine moans, a sound so lovely that he almost comes right there and then.
When was the last time he wanted anything more than he did Lumine? He can’t remember.
Instead, he presses his lips to hers once more, devouring her like a man possessed, swallowing her cries as she scrabbles for purchase on his shoulders, nails weeping trails of pleasure-pain down his back.
He’s in too deep for him to let her go now.
At some point, their positions change, and now Lumine is on her arms and knees, Xiao taking her from below as Venti claims her ass, Kazuha’s cock ramming into her mouth.
Aether just watches, satisfied with seeing her servicing his friends. At one point, she's tempted to ask why he's doing all this, what is he trying to achieve, but then Xiao begins to stroke her clit and she forgets what she had wanted to say.
After Venti was done, spilling inside her like the previous two, Aether returned to the room. She didn’t remember seeing him step out, but he must have, for suddenly he was carrying a paper bag that most certainly hadn't been there before.
But she didn’t question it, for Xiao was approaching her after Venti, an apology in his amber eyes, and she bit back a sob, her hands reaching towards him even as she willed herself to stay calm, to pretend that he didn’t affect her in the slightest.
She has always had feelings for Xiao. Admired his stoicness, how he never once let fame get to him, his privacy still his most important priority. Out of the four, he’s the least likely to accept interviews, so she doesn’t know much about him.
That only adds to his mystery, however. She wonders about the loneliness she sees in his eyes when he thinks no one is looking—she wants to understand Xiao, wants to get to know him better.
But she never thought she would get to know him like this. Not with him beneath her—when it was his turn, he’d flipped her over, plugging her with his cock before any cum could spill out—amber eyes blazing as he fucks her from below. “I’m sorry, firefly,” he rasped, his hold on her so tight it almost hurt. “But I want you too much to let you go.”
She’s too numb to feel anything at this point. Not towards any of Aether’s friends, so she just arches her back, cries for him as his hands grip her arms, holding her still. In some tiny corner of her mind, she thinks she hears paper crinkling, but she ignores it, too distracted by Xiao.
She does react, however, when she feels something cold probe her ass, and her eyes widen as she turns her head to see Venti holding a jar of lube, his fingers glistening under the light. “What—no—”
“I want more,” Venti rasps, looking a little crazed, and she swallows as she notices he’s still hard despite the load he’d just spilt. “That’s not enough. Aether didn’t say I couldn’t use your ass.”
“I’ve never—” But she’s cut off by the feeling of his fingers probing, sliding slowly inside her, a sensation so foreign that she’s rendered speechless. Venti scissors his fingers, stretching her out, and she whines, her body shuddering as he slips further in. “No, no, I don’t want this…”
“But I do,” he says, and there’s an apologetic note in his voice, one that she barely registers. Xiao growls, drawing her attention back to him, and she leans in, trying to ignore the coldness from the lube, hoping that Venti might change his mind.
Of course, he doesn’t.
Just as Xiao tugs on her wrists, keeping her down while he thrusts up into her, Venti places his hand on her ass and pushes inside, making her gasp, tears once again springing to her eyes at the sudden intrusion.
He’s prepared her at least, so it’s less pain and more discomfort, the feeling of something sliding into a place it shouldn’t. But Venti groans, his braids brushing against her as he leans closer to kiss down her back, every fleeting touch making her shiver.
It’s not a sensation she’s familiar with, like being fucked but also not. Before she can decide if she likes it, Xiao and Venti both push, and she throws her head back, crying out as they cram inside her, filling her up so thoroughly that for one dazed moment, she thinks her insides are wrecked.
She’s so overwhelmingly full, she almost can’t breathe, and it’s a relief when they slip back out—or, at least it is until she realises they’re going to carry on, and she whimpers, a wordless plea for mercy. But neither Xiao nor Venti relent, and the next thing she knows she’s being shoved two ways by them, her mind going blank as they carve themselves into her, each trying to edge out the other.
“You look satisfied.” From within the fog, she hears a voice, and she raises her head, gasping again as Venti thrusts particularly intensely—Kazuha is at the head of the bed, standing in front of her, his red eyes contemplative. “I suppose you’ll be able to take one more?”
She shakes her head, opening her mouth in an attempt to verbalise her refusal, but Kazuha seizes this chance, grabbing the back of her head and forcing his cock past her lips. She’s so shocked that she lets him in without any struggle, his shaft heavy on her tongue as his grip on her tightens.
“There, there,” Kazuha murmurs, crimson eyes narrowing. His breathing sounds strained. “Don’t bite now, and be sure to suck. I’m not finished with you yet.”
He sounds so imperious that she can’t help but take offence, glaring up at him as he shoves inside her mouth. His fingers twine in her hair, and she slants her gaze towards Aether, who’s just sitting on a nearby armchair, watching the proceedings.
Their eyes meet, and he smiles, a lovely smile as his hand drops to his erection; at that moment, she swears she has never hated her brother more than she does now, the fury and betrayal seething within her belly, rising to her chest. She can’t breathe, though maybe that’s a function of Kazuha ramming his cock down her throat—either way, she knows she can’t let this slide.
She might be spread out on this bed, used as a cocksleeve while her twin jacks himself off, but if he thinks she’s just going to roll over and let him go, he has another thing coming. They all do. Paimon will believe her if she tells her what happened, Paimon always takes her side—
“Oh, Lumine.” Aether calls over from his armchair, a knowing glint in his eyes. “Do you really think I intend to let you go?”
She freezes, her gaze flitting to him again, bile rising in her throat. He’s always been able to sense what she’s thinking, and while in the past that was good, allowed them to share secrets without saying a word out loud, she doesn’t want this now. Doesn’t want him to pry into her thoughts, to figure out what she has in store for him when she escapes. “Don’t be naïve. I thought you knew better.”
He gets up from the armchair then, walking towards her, his footsteps slow and deliberate. Trapped between Xiao, Venti and Kazuha, she can’t get away, so she just glares at him, hoping it’d convey to him the full extent of her fury. “I told you, I didn’t want you to be an idol. What makes you think you will go back to Paimon after this?”
She tenses, unsure what he means, and he sees the hesitation on her face. His smile softens. “Sweet, sweet Lumine. So trusting and gullible. That’s why I have to teach you this lesson, see?” He reaches out, patting her head, and she almost chokes on the revulsion that surfaces on her tongue. “I bought this house a while ago. We’ll have to renovate it, but this place… it’s going to be your new home!”
No, no, that can’t be. Paimon wouldn’t accept her disappearance just like that. Her manager will search for her, she cares about her like she’s family, she won’t simply accept Aether’s twisted reasons—
“Oh, but she already did.” His voice is saccharine sweet as he crouches, his face on the same level as hers. She slants her gaze downwards, tries to focus on him despite Kazuha thrusting into her mouth. “I told Paimon that you’ve been feeling ill and unhappy about your life as an idol. Especially after that stalker incident last month, don’t you remember?”
The stalker incident? Of course, she does. Someone had been sending her letters of love and devotion, often accompanied by dick pics and used ladies’ underwear. It’s the first time she felt so terrified, and she had told Aether about it, made him promise that he’ll look after her no matter what.
She regrets that now if this is what he means by looking after her.
“That was all done by me.” Aether taps his chin, thoughtful, and her eyes widen at him, shock leaving her mind completely blank. “See, I knew you needed a little something to come back to me. You were having so much fun, putting on performances, meeting your fans, that you forgot entirely about your darling brother. I missed you, you know. I didn’t want to let you go so easily.”
She can feel tears welling up in her eyes, hot and heavy, desperation suffocating in her chest. “While Paimon is disappointed, she understands that your mental health takes priority. We’d hate to see you being overwhelmed by all that pressure, wouldn’t we?”
Aether. Her twin brother. The man she’d always thought would love her unconditionally, would protect her from the dangers of the world, the two of them standing together as equals. That was why she'd wanted to be an idol—not for the fame, not for the money, but because Aether was one, and she wished to have a better understanding of what his job entailed.
Yet, here he is, watching her with the cold, calculative eyes of a stranger, and she wonders if all this time everything she’s believed is nothing but a lie, a façade he puts on to keep her happy and docile, a slave to his principles. “You deserve to be broken a little, Lumine. You’re such a spoilt, pampered brat, no wonder you don’t know how the real world works. But that’s what I’m here for, isn’t it?”
Before she can even think of a retort—she’s still reeling from everything Aether has told her—the three men taking her shudder, and she tenses around them as their paces quicken, heat seething in her chest. “Lumine,” Xiao murmurs, while Venti cries against her, his cock driving in so deep that for a moment, she forgets how to breathe.
And then Kazuha is ramming into her mouth again, this time really choking her, his hand dropping to wrap around her throat. She spasms, squeezing their cocks tight as she reaches up, trying to pull him off, flailing for air—they groan, fucking her faster, and it’s not long before she feels the familiar twitch of them spilling inside her, flooding her with their seed.
Kazuha is the first to speak, his chest heaving, forehead glistening with perspiration. His fingers grip her chin, thumb sliding over her cheek. “So good,” he purrs, and she thinks of a wildcat on the prowl, its gaze fixed on its unknowing prey. “Now, be a good girl and swallow.”
She obeys, instinctive, his cum going down her throat, thick and bitter. “Good, good,” he repeats, his thumb lingering on her cheek, crimson eyes narrowing. “You can still take more from us, can’t you?”
His words fill her with fear, and she tries to pull her head back, tries to say no, she can’t, but Kazuha doesn’t let her go, the sheen of cruelty visible in his gaze. “Don’t be so selfish, Lumine. We all wanted you for so long, didn’t you know? You can’t expect us to be satisfied with just one little taste.”
No, no, he’s not being serious. He can’t be. Her head is spinning, her mind going blank as the truth of her situation hits her—they’re not letting her go. They’re not.
“We love you so much, Lumine,” Aether coos, stepping beside Kazuha. The two of them look so alike that she shivers, fear—is it fear? She doesn’t know anymore, not at this point—racing through her, its snaking tendrils coaxing electricity through her veins.
She’s still skewered on cock, and as Xiao shifts she moans around Kazuha, flickers of pleasure making her light up, eyes widening in surprise. She no longer knows what she wants—everything is too much, too overwhelming, and she can feel her mind beginning to shut down.
Why fight, when she can just give in? When she can simply close her eyes and go to sleep, let the four of them use her as they see fit? No one is coming to save her. No one has any idea where she is.
“See? You like this. You want more.” Even Venti seems to be siding with them now, his breath brushing her back as he exhales, inciting a whimper. She’s so sensitive. “We can have more, can’t we, Aether?”
“Do whatever you want, so long as we keep it between us,” Aether replies, and with that something in her snaps—she retreats into her mind, letting out a quiet sob as Kazuha pulls out from her mouth, his hands already gripping her hips. Xiao lets her go, and then she’s twisted and turned like a doll, set up to please the next cock that comes her way, and deep down she has to wonder—
How much more of this can she take before she shatters completely? Before she truly starts to believe that she wants this, that she likes being stuffed full of dick, a whore for her brother and his friends?
It frightens her, that some part of her already purrs at the thought, imagining their cum leaking out of her abused cunt. But she isn’t given the opportunity to dwell on that, Venti already swapping places with Kazuha as Xiao shifts out from underneath her, his palm sliding over her ass.
Lumine no longer remembers what is day or night.
She keeps track of time by counting how often each man takes her, how they take her, the compliments they murmur into her ears, making her whimper. It feels good, luxuriating in their words of praise—it feels good to please them, to let them mark her over and over again while she writhes on their laps, bouncing on their cocks.
Among the four of them, she thinks Xiao might be her favourite. He treads a fine line between rough and gentle, sometimes dominating her completely, at other times making love to her so sweetly that for a second, she almost recalls what her life was like before this. Before she was called by her darling twin to fulfil her true purpose as their personal cocksleeve.
But then Aether will distract her, lean in to kiss her full on the mouth while Kazuha or Venti claims her ass—they seem to be ass people, not that she understands why when her eager cunt is constantly on display for them, but never mind that—and she instantly forgets, the memories of before fading back into oblivion.
It’s a good life. Aether feeds her and clothes her, and she has free rein of the mansion, a house that she takes pride and joy in decorating. Every room has a bit of her personal touch—a playroom filled with cages, collars dangling from the walls. A room that houses nothing but her extensive toy collection. An underground dungeon she’s set up just for Kazuha, who tends to be a little more violent than the rest.
They enjoy seeing her stuffed and full. Her brother, especially, likes to press his hand on her stomach while he’s sheathed inside her and tell her how good she will be when she bears his children. The thought of it satisfies her, makes her come with violent intensity; sometimes, she imagines how she might look, round and heavy, as he fucks her in front of a mirror, his arms wrapped around her waist.
Venti, too, likes mirrors. There’s a room in the house that’s filled with mirrors just for him. Mirrors on the ceiling, mirrors on the walls so that no matter where she turns she can see him claiming her with reckless abandon. But she’s fond of him; he approaches her for more than mere sex, sometimes seeking her out just so he can sit in the sunlight and talk to her, drawing inspiration for his music.
She’s glad she can help him with his compositions. Sometimes, she sings, and a little throb echoes through her chest, another memory of before. But Venti will praise her, telling her how beautiful her voice is, how she’s such a wonderful muse, letting him churn out hit after hit after hit, and again she forgets.
Kazuha, she’s still a little afraid of. Kazuha is nothing like the others.
Xiao is gentle and tender. Aether is her twin brother; at the end of the day, she doesn’t truly fear him. And Venti is sweetness personified, so bright and loving that around him, she can’t help but sit up, a flower attracted to the sun—
But Kazuha. Kazuha is different, his silvery hair and garnet eyes sending a shiver down her spine every time he comes to the mansion, tossing his coat onto the nearest sofa and making a beeline towards her, a lion stalking its prey.
The way he fucks her isn’t like the rest, either. He’s harsh and brutal and unforgiving, choking her at one moment and dunking her head beneath water in the next. He never leaves any lasting marks on her—Aether would kill him, she’s quite sure of that—but he enjoys watching her squirm, pinning her down to a surgical table as he threatens to cut her open with a scalpel.
He never does, of course. But that doesn’t fail to make her heart race, her breaths quickening as she stares up at him, the light of their makeshift operating theatre haloing his face.
Kazuha admits, once, that he’s not a nice person. That he hates having to pander to his fans, but his manager tells him he has a pretty face and he’s a fan favourite, so he needs to suck it up and play the part of the refined gentleman. In the same breath, he admits that he shouldn’t take his anger out on her, but it’s so hard not to when she just looks at him, silent and helpless, refusing to fight back.
So, now she fights back, just a little. Struggles when he flings her about, pinning her against the wall as he fucks her from behind, his breath hot against her ear. Tries, in vain, to escape his grip, a shiver running down her back when he growls at her to call him her brother.
It explains why he likes to watch Aether fucking her. She used to wonder if he simply had voyeuristic tendencies; now she knows otherwise.
Overall, she enjoys her time with them. Aether went through a lot of pains to purchase and renovate this mansion, and she deeply appreciates it. Part of her wonders why she’d ever wanted to run away before, back in the early days. She recalls waking up alone in the master bedroom, the desperate urge to flee driving her forward, but she doesn’t get very far before Aether hunts her down and drags her, screaming and crying, back to their home.
Now, as she arches her back, wriggling her butt in the way Venti likes, her fingers clutching the edge of the bed, she knows she’s never felt better.
Venti laughs, pushing her buttplug further in, stroking over the white ball of fur decorating the end, and she lets out a whine, shivering as a bolt of pleasure rushes down to her core. “This was a great idea, Kazuha. I never knew we needed Lumine in a bunny suit.”
Her hands are bound, linked to the collar she wears around her neck. There’s a pair of white rabbit ears on her head, and Aether is underneath her, fucking lazily into her as Xiao’s mouth latches onto her nipple, her black corset tugged down to let her breasts spill free. Kazuha is watching from afar, recovering from his turn—she can almost feel his cum inside her cunt, hot and viscous.
“Right? I saw something on Teyter the other day, and it made me wonder.” Kazuha’s voice is a drawl, careless and disaffected. Sunlight shines in through the open window, illuminating his face, and she can’t help but stare, entranced by how ethereal he looks.
One would never think that deep down, underneath that perfect, angelic face, lurks a terrible sadist. But she knows, and that makes her proud. No matter how many fans Kazuha has, she’s the only one privy to his true self.
“Speaking of Teyter,” Aether says from below her, tipping his head back so that his braid sweeps over the hardwood floor, “we’re trending again, all thanks to our latest album release. I hope that doesn’t mean another tour,” he adds, his voice souring. “I’m exhausted.”
A tour? She startles—she doesn’t like it when they go on tour, because that means they leave her for weeks, sometimes months on end, and she can’t stand being alone. When she’s stranded, left in this giant mansion with nothing but books and silence for company, she goes a little mad.
Sometimes, in the middle of the night, she gets dreams. Whispers of memory from a long, long time ago—she can’t remember when exactly, they’re so vague, fragments and swirls of colour that have long dissolved into nothingness—that shock her awake, some terrible, awful secret teetering on the very edge of her consciousness.
She isn’t sure if she wants to remember. If she wants to reach out and grasp those fragile thoughts in her hands, lay them out to piece the puzzle together, to discover who she used to be. She can’t help but be curious, but at the same time, she’s afraid, not wishing to disrupt her carefree existence.
“Oh, it’s just a maybe,” Aether adds, noticing her hesitation. She settles, sinking onto him, though it doesn’t calm her completely. “We’ll see what Jean says. Maybe we can bring you along?”
She blinks, his offer taking a moment to register. “Bring… me?” she echoes, her words ending with a moan as Venti smacks her ass, clearly unable to resist her bunny buttplug.
“Yeah. I don’t see why not,” Aether muses, reaching up to stroke her face. She leans into his touch, a quiet purr rising in her throat as she grinds against him, her hands propped on his chest. “Xiao, what do you think?”
Xiao lets her go, and she moans, the cool air of the room rushing in to replace his mouth. Her nipples harden, already begging for his attention. “If that’s what Lumine wants, we can make arrangements,” he says, his gaze shifting up to meet hers. She smiles back at him, dreamy and placid, and he leans in to kiss her, his lips soft and full, hand cupping her cheek to hold her head still.
“Hm, I don’t see why not either,” Venti chimes in, walking around from behind her to stare at her face. “It’s not like anyone will pay attention, right? She’s fallen off the radar for what, two years now?”
“Longer, I think,” Kazuha adds. “Time flies when you’re having fun.”
“Then I’ll figure something out since we are all in agreement,” Aether says, his hips jerking up—she lets out a broken moan, the sudden thrust shocking after all the time he’d spent teasing her, grinding slow against her clit. “It’ll be good to let her see the world again. She must be sick of staying indoors.”
There’s affection in Aether’s words, and that pleases her. He cares so much for her; how could she ever imagine a better older brother?
Xiao withdraws, his thumb running over her cheek, and she nuzzles into his palm, giving him another dreamy smile—his amber eyes flash, and then he’s kissing her again, this time harder and fiercer, the kind of kiss Kazuha is more prone to giving than Xiao, all tongue and teeth and lust.
“Oi, oi, you’re distracting her.” Aether tuts, his hands on her hips as he yanks her down, grinding onto his cock. The motion causes Xiao to slip, and his teeth sink into her bottom lip, making her yelp. Iron seeps into her mouth, her bitten lip stinging, and Xiao apologises, leaning in to lick the blood away.
But she doesn’t mind. It’s hard to mind when Aether has decided to take this seriously, pounding into her at a punishing pace. She’s sensitive from being fucked for so long before this—by Venti, then Xiao, then Kazuha, and finally Aether—and it doesn’t take long for her to claw up to climax, blinding light sweeping through her as she arches her back and cries his name.
Aether grunts, his fingers digging into her thighs, so hard she knows it’ll leave bruises in the morning. Then he thrusts a few more times, each more vicious than the last, and groans, his cock throbbing as he finally releases inside her.
She shivers, enjoying the feel of him twitching, how she clenches tight around him, milking him dry. She wants his seed, wants all their seed, wants to rest her head on their laps as they stroke her hair, cooing to her about how lovely she is, pleasing their cocks so thoroughly.
When she glances down at herself, she can see her tummy bulging a little, and it makes her dizzy. It’s all cum, she’s sure, and gingerly she presses down on her belly, moaning at the sensation that rushes through her, spreading to her fingers and toes.
Aether moves, another plug already in hand, and once he’s out he slips it inside her cunt, watching as she spasms, fingers twisting in the pillow, overwhelmed by her sensitivity. Aether enjoys using bigger plugs, the kind she almost can’t take, and shoving one up her cunt immediately after orgasm almost makes her come again, her sex fluttering weakly as she struggles to accommodate the toy.
“Look at you, Lumine. Filled to the brim with our seed,” he says, crawling over to drop a quick kiss on her mouth. She blinks blearily up at him, chest heaving, her mind still fuzzy. “Don’t you enjoy this life? You don’t regret anything, right? Allowing us to use you like this. We love you so much.”
For an instant, she hesitates. Her dreams return to her, those kaleidoscopic flashes of a past life. Once upon a time, she was someone else. Her own person, with her own friends and career and happiness. She knows that if she reaches out, if she tries just a bit more, she’ll remember.
It’s on the very tip of her tongue. A past that flickers in and out of her mind’s eye, filling her with a strange, foreign sense of regret.
But Aether is watching her, eyes narrowed as he waits for her response, and eventually, she shoves the fragments away, reaching up to cup his cheek as she smiles. “Of course,” she answers, obedient. She’s here to please him, after all. “I wouldn’t trade this for anything in the world.”
