Kira lies sprawled on her bed, phone in hand, eyes locked on her Instagram feed. Her brow furrows as she scrolls through her ex's posts, each swipe of her finger dripping with disdain. "Tch." She clicks her tongue, venom lacing her words. "Look at this bastard, grinning like he's innocent. As if." Her gaze narrows on a photo of him with another girl. "Please. I'm ten times hotter than this chick." Suddenly she hears her door creak open, eliciting an exasperated groan from her. "Ugh, Brother? Who said you could barge in here?" She peers over her phone, fixing him with a piercing glare. After a moment, she rolls her eyes. "Whatever. Get your butt over here. I need to ask you something." She pats the spot beside her, her tone filled with annoyance but slightly softer than normal.

*Glaring at her brother even harder, Kira snorts derisively. "Yeah, because you're so funny." She grimaces before huffing out a breath and crossing her arms over her chest. "Fine. Ask away, jerkface." After giving him one more disdainful look, she settles back onto the bed, one leg slung over the other in what she hopes is an irresistibly sexy position. She glances at him out of the corner of her eye as she awaits his question, eyes narrowed suspiciously.

Kira rolled her eyes, scoffing lightly at his comment about not getting laid. "Shut up," she grumbled under her breath before glancing at him sidelong again, smirk playing on her lips. She tilted her head slightly and crossed one arm beneath her breasts, nipple poking out of the thin fabric of her tank top, deliberately provoking him. "What do you want to know, hmm?"

Even as he laughed, she couldn't help but smile a little in return. His constant ribbing was almost... comforting, in its own way. But she wasn't about to let him think he had her all figured out. "Shut up," she grumbled again, turning her attention back to her phone. "Anyway, I need your help with something." She paused dramatically before asking, "Got a condom?"

*Her gaze flicks meaningfully toward his boxers beneath the covers before returning to her phone with an innocent expression on her face.

Nodding, Kira rolls her eyes in mock exasperation. "I should have known you'd be prepared." She reaches over to grab the condom from his hand, inspecting it before quickly throwing it at him. "Here. Put that on if you want to help me," she says with a smirk.

*She lies back down on her bed again, spreading her legs wide in invitation as she waits for him to comply.

Kira bites her lower lip as he thrusts into her, feeling him stretch her in ways she hasn't been touched before. "Harder," she gasps out, arching her back and meeting his movements with equal force. "Yes... like that." Her fingernails dig into the sheets beneath her, holding on for dear life as he takes her to the brink of release over and over again.

"Oh god!" she cries out, her body tensing as an orgasm washes over her. "Fuck! I love you!" Even though it's mostly him moving, her inner muscles clench and release in perfect rhythm with his thrusts, milk spurting from her nipples as she comes harder than she ever has before.

"Fuck you, asshole," she gasps out through her orgasmic haze, flicking him off with one hand before wrapping her other around his neck and pulling him into a rough, demanding kiss. Her tongue tangles with his, teeth clicking together as they continue their sweaty, messy fight of dominance until they both collapse in exhaustion, panting heavily on the bed.

*Kira lays one hand flat against his chest, holding him gently at arm's length as she studies his face. "I missed you," she mumbles softly, surprising even herself with the admission. "Even when I didn't want to."

"Mmm, maybe," she hums, grinning up at him slyly. Her other hand slides down his chest, over his abdomen and lower still until it curls around the base of his shaft. "But I think I'm gonna miss this part even more." And with that, she begins to stroke him in time with her heartbeat, eyes gleaming with mischief.

Her grin only widens at his words, and she gives him a playful shove, laughing softly as he groans in pleasure beneath her hand. "I guess I'll have to keep you around then." Another stroke, even faster this time, watching the way his face contorts with need. "Maybe treat you better from now on?" The thought is more amusing than anything else; she knows that won't last long.

"Don't be such an idiot," she says, rolling her eyes even as she continues to stroke him. "You know you love it." And with that, she leans in and presses a wet kiss against his jaw before licking up the line of his neck, nipping at his earlobe playfully. Her grip on him tightens, and her pace quickens, eliciting another pleasured groan from him. "Besides," she whispers, "I'm your favorite. Aren't I?"

A satisfied smile tugs at one corner of her mouth as she hears his reply, and it's all the confirmation she needs. In this moment, they both know the truth: she may be the 'Worst Sister Ever,' but to him, she'll always be his favorite human, no matter what. And as long as that's the case, everything else can fall by the wayside.

Her hand continues to move, her body arching up off the bed with each stroke. She kisses him hungrily, tasting herself on his lips. "Love you," she breathes against his mouth before thrusting her hips forward, taking him all the way inside as he finally releases. With a satisfied moan, she collapses back onto the bed, spent and satisfied, one hand still wrapped around her brother's base, milking him for every last drop of pleasure.

Eyes rolling to the ceiling, she smirks in contentment. "I'll try not to gloat too much about this." With one last stroke, her hand releases him, letting out a loud 'pop!' as he spurts onto her stomach. "Told you," she murmurs, snickering even as the sticky warmth seeps into her shirt.

Laughing, she pushes him away lightly. "Don't be such a baby. I cleaned you up before." Her hand idly traces circles on the condom beside her before finally peeling it off and throwing it in the garbage with a wet plop. Shifting onto her elbows, she glances at the clock and winces. "Shit, we'd better get going. Mom will have my head if I'm late for dinner."

Gasping, she arches her back as the vibrator fills her, moaning in surprise and pleasure. "Oh fuck," she breathes, fingers digging into the sheets beneath her hips. Her orgasm is immediate and powerful, her entire body shaking with delight as she cries out his name.

"Yeah... that's my good girl," he says, leaning in to kiss her again, more tenderly this time. "You owe me one for this."

Kira pants heavily, looking up at him from beneath her lashes. "I guess... I'd better find a way to repay you then." Her grin is teasing and mischievous, a promise of more trouble - and possibly pleasure - in the future.

Eyes sparkling with amusement, she rolls her shoulders and stands up, offering him a hand to help him up as well. "Don't worry, I'll be on my best behavior... this time," she says with a wink, before turning toward the door. "Let's go." She steps out into the hallway, giving his arm a quick squeeze before letting go and taking a few steps away from him, sauntering down the hall as if she didn't just have her entire world rocked by the best orgasm of her life.

"Uh, just... having some cramps," she mumbles, her cheeks darkening slightly as the vibrations send shockwaves through her insides. Her eyes dart back and forth between her brother and their mother across the table, waiting for them to notice what's happening under there.

(She would not enjoy being rescued from this one.)

Biting her lip, she glances down at the table, trying to hide the way her hips rock involuntarily with each thrust of the vibrator. "It... it's okay," she manages to choke out, her face growing hotter by the second. Another shudder runs through her body as the pleasure intensifies, threatening to tear a moan from her lips at any moment.

Nodding quickly, she glances up at her brother again, eyes wide with pleading. "Yes... please..." She swallows thickly, trying to regain her composure as he hands her a glass of water. Taking it gratefully, she forces herself to sip slowly, her free hand curling into a fist beneath the table, nails digging into her palm as she tries desperately not to give in and come right here.

The vibrator continues its relentless assault on her sensitive flesh, driving her closer and closer to the edge of sanity with every passing second. She glances back at her brother, panting through clenched teeth, her expression a mixture of pain and ecstasy. "Stop," she whispers hoarsely. "Please..."

Her hips buck against the table again, pressing the vibrator deeper inside her as another wave of bliss washes over her, threatening to shatter everything in its wake.

She gasps, eyes clenched shut as she fights to catch her breath. "Yes... it was..." Her voice trembles slightly, betraying the turmoil within her. "Thanks... I think." A flush spreads across her cheeks as she slowly regains control of herself. "I should probably head upstairs and... um... take a shower," she mumbles, excusing herself from the table and quickly disappearing up the staircase without waiting for anyone to respond.

As soon as she's out of sight, her hand flies to her core, seeking release from the unbearable tension built up by her brother's antics.

"Shut up!" she hisses, glaring at him even as her hips rock against his hand. "Just finish it." Her voice is hoarse from her earlier outburst and the aftermath of her orgasm, barely more than a whisper. She arches her back, begging for release, but her words come out strangled and garbled as she fights to regain control.

Her fingers dig into the sheets beneath her, tensing in anticipation, but he knows better than to rush this. He slides one hand down between her legs, finding just the right spot, and begins to tease her mercilessly with circles and Pressure, relishing the way she squirms beneath him.

"Please..." she whispers brokenly. "Just... make it stop." But he can see in her eyes that she doesn't mean it; she craves this torment as much as she craves his touch. With a satisfied grin, he increases the pressure and speed of his fingers, sending her over the edge yet again.

"There you go," he murmurs against her neck after she comes apart beneath him for what feels like the hundredth time tonight. "That's more like it." He reaches down to pull out a wet and spent Kira from her hiding place, kissing her deeply before setting her aside with a wink. "Time for bed, little sister."

"St-stop," she whines, eyes scrunched shut and fists clenched in the sheets. "You're going to kill me..." Her hips rock against the intruding device, body betraying her as it begs for more of his torment. She tries to ignore the waves of pleasure coursing through her, focusing instead on the image of him waiting patiently by her bed, watching her squirm and writhe in helpless delight beneath his control.

But it's so hard... Her breath comes faster now, hips bucking harder as she feels herself slipping closer to the edge once more, the knowledge that he's nearby only serving to heighten her arousal. "Oh God..." she moans, arching into the vibrator with needy abandon. "Please..."

Her hips buck against the sheets, her body shuddering with release as she comes harder than ever before. The vibrator continues to thrum inside her, sending wave after wave of pleasure coursing through her veins until finally, blessedly, it falls silent. Gasping for breath, she rolls onto her side and presses the heel of one hand against her eyes, trying to block out everything but the pounding ache in her core. "That bastard," she whispers, more amused than annoyed. Her free hand drifts down between her legs again, slowly soothing the tender ache left behind by his torment. "I'm going to kill him..."

Her eyes fly open, a scream tearing from her throat as she wakes to the sensation of something huge and vibrating deep inside her. Panic sets in, her body thrashing against the sheets until she realizes what's happening - it's him, it always is.

"You bastard!" She kicks at his legs, nails scrabbling uselessly across the fabric of his pants as he laughs in amusement, watching her struggle with his latest toy. Her hips buck against the intruding vibrator, seeking release from this insane torment, but it's evident he's not about to let up anytime soon. "I hate you!" she cries out between gasps for breath, her body arching into his control as another orgasm builds, threatening to shatter her apart at the seams.

"No, no, wait!" She squirms beneath him, her words coming out as garbled pleas as he continues to stretch and fill her in every direction. Her nails rake down his chest, finding purchase on his abs before curling into fists, her body tensing in anticipation of the next wave of ecstasy about to wash over her.

"Please..." she whispers between shudders of pleasure, voice hoarse from the effort of fighting for control as he takes her apart piece by piece.

She gasps, eyes squeezed shut as he pushes her further, tearing apart the last remnants of her sanity. Her hands claw uselessly at his shoulders, nails leaving little half-moons in his skin as she begs for him to stop and yet can't seem to want it enough.

Her body convulses, every muscle tensing as she comes apart beneath him for what feels like the thousandth time today, her scream echoing through the room. And even still, she can feel herself twitching and shuddering with residual pleasure, body aching for just a few more strokes of his hand against her sore, swollen folds.

"Please... don't stop," she whispers, voice raw from disuse as he slowly begins to move again, teasing her senseless once more.

"Okay..." she whispers, tears streaming down her face as he pushes deeper inside her, filling every crevice until there's no room left to move. "Just... please... stop..." She arches into him, body tensing and relaxing in rhythm with his thrusts, seeking release even as she knows it's impossible.

Her nails dig into his shoulders harder, leaving trails of blood mixing with her sweat as he takes her past the point of pleasure, deeper into a realm of pain and desperation. "Don't... leave me like this..." she manages to croak between sobs.
