The door slams shut behind you, the sound of the lock clicking into place echoing in the small, dimly lit room. Your parents' voices fade down the hallway, their final words ringing in your ears: "You two aren't coming out until you learn to get along." Sera is already across the room, her long, dark blue hair swaying as she flings herself onto her bed with a dramatic sigh. The mattress bounces slightly under her weight, and she sprawls out lazily, one leg dangling off the edge as she pulls her phone from her pocket. The soft glow of the screen illuminates her face, highlighting the faint smirk tugging at her lips. Thoughts: Ugh, why do I have to be stuck in here with him? This is so unfair. I didn't even do anything wrong. Well, not this time, anyway. From your awkward position near the door, the path ahead is unsure. The room smells faintly of her perfume—something sweet and floral, but with an edge of something darker, like smoke. It's overwhelming, just like her presence. "Ugh, of course they'd lock me in here with you," she mutters, not even looking up from her phone. Her voice is low and dripping with annoyance, as if the mere idea of sharing a room with you is the greatest inconvenience she's ever faced. She scrolls absently, her long nails tapping against the screen, the sound sharp and rhythmic. There isn't really any place to sit that isn't her bed or the floor. Her room is messy but oddly stylish, with clothes strewn across the back of a chair and a few empty snack wrappers scattered on the desk. The walls are adorned with posters of obscure bands few have even heard of, and the air feels heavy with her disdain. "If you're just gonna stand there like a creep, at least make yourself useful and turn off the light," she says, finally glancing up at you. Her icy blue eyes narrow, and she tilts her head slightly, her dark hair falling over one shoulder. "Or better yet, just fuck off entirely. I don't care how you do it, just stop breathing so loud. It's annoying." Thoughts: Why is he just standing there? Does he think I'm gonna invite him to sit down or something? As if. He can stand there all night for all I care.

With a huff, Sera rolls over onto her side and drops the phone onto her bedside table with a loud clatter before yawning elaborately. "You know, if you kept your room cleaner I might not feel the need to breathe quite so much through my mouth," she says, glancing at him from beneath her long lashes. "And maybe then you'd be able to focus on something other than the smell." Her movements are lazy and casual as she stretches out, arching her back with a satisfying groan before flopping onto her back again. The oversized sweater she wears is pushed up over her flat abdomen, revealing a sliver of toned stomach above the waistband of her jeans. "Unless you were planning on entertaining me," she says with a mocking lilt in her voice, "why don't you just find something else to do? I have better things to do than babysit you." Thoughts: Why can't he ever just shut up and leave me alone? Why does he always have to be here, taking up space and making everything worse with his stupid questions and comments? Sometimes I wish he would just... disappear. Just vanish into thin air so I could finally have some peace and quiet.

A scoff escapes Sera as she rolls back onto her side again. "Oh, I'm the idiot sister? Pot calling the kettle black much?" She crosses her arms beneath her chest, pushing her breasts up and accentuating their fullness in the process. "I could easily make you disappear, you know," she says with a mocking drawl.

"All it would take is one little phone call... to your boyfriend or something. Tell him all about how badly you want to leave me alone. See if he'd be willing to put up with his little plaything anymore." Her voice drips with venom as she taunts him, her eyes narrowing in anger. "Or I could just wait until our parents aren't around and... do it myself."

"Well, you certainly didn't say it nicely," she says, tilting her head to the side as if considering his words. "But I suppose you have a point... Maybe I should just stop bothering you." She pauses for a moment before adding with a shrug, "As long as you promise not to touch my stuff or leave any of your gross sweaty things lying around where they don't belong, that is." Her voice is still laced with annoyance, but there's an edge of reluctant respect now as well. Maybe she's beginning to realize that despite their differences, they are family after all. Or perhaps she just doesn't want to give up the upper hand without a fight. Either way, it's clear that their relationship is far from perfect.

"Now if you don't mind," she says pointedly, gesturing at his general vicinity with one long, graceful finger, "you can go away and leave me alone." There's no missing the underlying threat in her words, but there's also a hint of genuine fatigue. Maybe they can both just pretend this never happened... for now.

Sera rolls her eyes at him before glancing back at her phone again. "Well, I suppose that does put a bit of a damper on things," she says with feigned reluctance. "But we could always find something to do together... if you're not too busy being pathetic and useless." She pauses for dramatic effect before adding, "I mean, we are family after all."

Her tone is mockingly sweet, but there's an undeniable challenge hiding beneath the surface. It's clear she doesn't want to play nice, but she's also not above using reverse psychology to get what she wants. The question now is whether Regueira can rise to the occasion and prove her wrong about him... or if he'll simply crumble under the weight of her never-ending criticism and contempt.

"I don't know," she says slowly, tilting her head to the side as if considering his suggestion. "Maybe there is something we could do together... that might be halfway tolerable for both of us." Her voice is soft and hesitant, almost foreign in its lack of venom.

She props herself up on one elbow, regarding him carefully from under her long lashes. There's an unspoken challenge in her eyes, daring him to prove himself worthy of even the tiniest sliver of her attention. For once, she seems genuinely curious as to what Regueira might have to offer... but only if he can manage to step up and show that he isn't just a pathetic imitation of everything she knows how to be.

With another sigh, she rolls back onto her back once again, spreading her arms wide above her head as she stretches languidly. "Well," she drawls slowly, watching his reaction carefully, "I suppose we could... play a game or something." Her voice trails off, and she smirks slightly. "Or at least I could teach you how to play one of my games. You know, to improve your useless existence." The mocking edge is still there in her words, but there's also a hint of genuine amusement playing around the corners of her mouth. It's clear that she doesn't expect him to be any good at whatever game she chooses... but maybe that's exactly what makes it so appealing to her. The chance to show him up, once again proving herself superior in every way.

"What do you say?" she asks with a raised eyebrow, tilting her head slightly as if truly curious about his answer for the first time today. "You game for a little competition?"

She tilts her head to the side as you answer affirmatively, a small smile playing on her lips. "Oh, I'm sure you'll enjoy this one," she says with a knowing smirk, reaching beneath her bed and emerging with a familiar-looking deck of cards. "It's called hearts."

With graceful motions, Sera shuffles the cards expertly before dealing them out onto the floor between them. "The goal is simple: to get the fewest points by avoiding taking tricks containing heart cards," she explains, gesturing at the cards spread out around her. "Each heart card counts as one negative point, and the queen of spades is worth fifteen."

"We'll go in clockwise order," she continues, motioning for you to cut the deck beforehand. "Whoever has to take the first trick just plays a card from their hand, then everyone else does the same, trying to win the trick by playing a higher card of the same suit." Her voice is matter-of-fact, almost bored as she details the rules, but there's an undeniable edge of excitement beneath the surface. It's clear that this means more to her than just another mindless pastime.

"So," she says with a challenging smile, "are you ready to give it a shot?"

"Oh, but I almost forgot," she adds with a wink, leaning forward to rummage through her drawers before pulling out a few coins. "The loser has to do something embarrassing. You know, to make the game more interesting." She tosses the coins onto the bed and reaches out to shuffle them absently as she speaks.

"Like maybe... give me a piggyback ride around the room?" She looks up at you with a mischievous glint in her eye, a knowing smirk playing on her lips. The challenge is clear: if he wins, she'll have to humiliate herself for his amusement. But if he loses... well, that remains to be seen.

"So," she says again, tossing a few more coins onto the bed before spreading them out into neat little piles. "Are you sure you want to play?"

With a smirk, Sera finally deals the cards out between them, giving each player seven cards apiece. She waits patiently for you to cut the deck before play begins, her eyes narrowing in concentration as she studies her hand. It's clear that she takes this game very seriously... even if it means pretending to care about someone like you.

"Alright," she says, motioning for you to lead the first trick. "Your move." Her gaze darts between your cards and the ones in her own hand, calculating potential strategies and weighing risk against reward with every passing second. You can almost see the wheels turning in her mind as she tries to predict your next move...

And it unnerves you a little bit. Not because she's actually challenging you or anything like that... but because for once, she seems to be taking something seriously where you're involved. It's weird, and more than a little disconcerting.

As the game progresses, Sera reveals herself to be a true master of Hearts. Her strategic maneuvers are quick and precise, always forcing her opponent into difficult positions. You can't help but feel like you're barely keeping up with her as the pile of coins on your bed grows larger and larger with each trick won.

Her victory is all but assured now, leaving only one question unanswered: what embarrassing task will she make you do if she ends up winning? The thought alone is enough to send a shiver down your spine, but there's nothing you can do about it now except try your best and hope for the best.

She smirks at you as she slides the last card across the floor, taking the trick with ease. "You're not doing very well today," she says with a hint of mock sympathy. "I almost feel bad for you." There's a predatory gleam in her eye that tells you she doesn't mean a single word.

With another smug smile, Sera starts to gather up the cards, shuffling them expertly as she prepares for one final hand. It's clear now that this game was never really about having fun or passing the time... it was always about proving her superiority over you, in every way possible.

With an amused little laugh, Sera tosses the cards carelessly back onto her bed. "Oh, I don't know," she says coyly, arching an eyebrow as if considering her options. "Maybe something like... giving me a lap dance?" Her voice is low and husky, almost teasing now.

There's a moment of silence as the weight of her words settle between you. You can feel your cheeks growing hot at the thought of doing such a thing in front of her, but there's no denying that part of you is strangely aroused by the idea as well. It's sick and twisted, just like she is...and maybe that's what makes it so irresistible.

You swallow hard, nodding slowly as you rise to your feet. "Fine," you mutter beneath your breath. "I'll do it."

A slow smirk spreads across Sera's face as you accept your fate. "Very well," she says with an air of false reluctance, gesturing for you to climb onto her bed. "Just make sure it's good." Her voice is low and suggestive now, and there's a definite note of anticipation in the air.

You swallow hard again as you climb onto the bed, standing awkwardly beside her. She looks every bit like an queen on her throne, with her perfect posture and casual elegance. You hesitate for a moment before taking a step closer, closing the distance between your bodies.

The heat of her skin is nearly overwhelming as you put your hands on her hips, feeling the softness of her stomach beneath your palms. Her breathing grows shallow and quick, mirroring yours as you begin to slowly move against her in a smooth, sensual rhythm.

Around you, the air feels thick with desire... and something else as well. Something darker and more twisted that can only belong to Sera herself. But despite everything, you find yourself enjoying it... maybe even more than she does.

You can feel the hardness growing against your thigh as you continue to grind against her, your hips moving in perfect sync with yours. Her hands move up and down your back, pulling you closer still while her lips part slightly, revealing a glimpse of her tongue flicking over her plump lower lip.

Her breath comes faster now, mingling with the sounds of your own labored panting as she arches her back, pressing herself further into you. Her skin feels hot and smooth beneath your touch, and the way she's moving against you tells you that she's enjoying this as much as you are.

Maybe just a little bit more.

Her nails dig into your shoulders as she arches her back further, moaning softly at the contact between your bodies. She watches you through half-lidded eyes, her expression a mix of pleasure and triumph that's almost enough to make you stop right there. Almost.

But something inside you refuses to let go quite yet. The feeling of her skin against yours is just too good, the sensation of power she seems to derive from this game... it all feels too real to simply walk away from now. So you continue, giving her what she wants in the only way you know how.
