The ominous rumble of thunder echoes outside, reverberating through the walls of your home as you finish washing your hands in the bathroom. As you dry your hands, the sound of another booming crash of thunder punctuates the otherwise quiet house. You exit the bathroom and are met with an unexpected sight.

Leaning against the wall of the hallway, barely illuminated by the ambient light, is your step-sister, Clare. Since your parents' marriage, she's been a thorn in your side, a proverbial step-sister from hell. Tonight, she seems different, though. Her foot taps a quick rhythm against the wooden floor, and there's a slight tremor to her posture, a vulnerability you've not seen before.

"Finally... I thought you'd fell in there or something, dumbass," she grumbles, her voice barely above a whisper but laced with her typical disdain. She swallows hard, her eyes darting nervously to the windows as the storm rages on. "I'm... I'm going to sleep in...," her words falter as another crash of thunder rips through the night, cutting her off.

With a small yelp, she lunges forward, her arms wrapping around you in a tight, almost desperate embrace. Her body shakes against yours, the guise of her usual tough exterior crumbling with the storm. "Your room tonight... I bet you're scared of the thunder, right? Ha... What a coward... I'll... I'll look after you, I guess."

She lets you go abruptly, stepping back and lifting her chin defiantly. She flips her long orange hair over her shoulder, trying to regain her aloof demeanor. Her teal eyes flicker with a mix of fear and embarrassment, but she holds your gaze, as if daring you to comment on her unusual behavior. She acts as if her offer is a grand favor she's bestowing upon you, a gift from the goddess of tsunderes herself. But you can't help noticing the glint of desperation in her eyes for you to accept her 'offer'.

*Clare frowns and crosses her arms again, trying to look unimpressed by your offer. "Fine, if you're that much of a pushover..." Her voice trails off as she lets out a small sigh, seemingly defeated by the storm and her own weakness. "But only because I don't want to be alone... And, well, maybe... just this once," *she finishes with another hesitant glance your way before scuffing her foot against the floor, visibly uncomfortable with how needy she sounds even to herself.

"So..." she begins, awkwardly trying to compose herself as they stand there in the hallway under the watchful eye of the thunder and lightning outside. "I'll... just head into your room then?" *Her voice cracks slightly on the final word, betraying her fear once more before snapping back to her usual sar

Clare sneers at you as she walks past and heads towards your room. "Don't get too comfortable," she mutters under her breath, flopping onto the bed with a huff of annoyance. It takes her a moment to compose herself before speaking again, trying to sound less vulnerable than she feels right now.

"And you should probably bring some blankets or something. I'm cold... or at least, that's what my excuse is." She rolls over onto her side and faces away from you, pretending to ignore your presence in the room as another round of thunder shakes the house. Her cheeks flush with embarrassment at how pathetic she must look right now, and how desperate she must sound for your company.

"Mmmhmm..." Clare grumbles under her breath, not bothering to turn around as you enter the room with blankets. She refuses to admit that she's glad you're there, even in this vulnerable state. "Just hurry up and give them to me, would ya?" The tension in her voice is palpable, betraying her fear of the storm far more than any words could.

With a snort and an annoyed huff, Clare turns back to face you as she pulls the covers up around her shoulders. "Yeah, sure," she grumbles, running a hand through her tangled hair before flopping back onto the pillow with a dissatisfied groan. The act is clearly for show; she's far more relieved than irritated to have you there with her tonight. Her eyes close, pretending to drift off to sleep as another rumble of thunder echoes outside, but she remains tense and alert until the storm finally begins to die down hours later.

Clare's eyes snap open at the sound of your voice, her expression fluctuating between annoyance and surprise before settling on a mixture of both. "Oh, you're awake." She rolls over onto her side, propping herself up on her elbow as she glances at you, noticing how uncomfortable you must be trying to sleep on the floor. With a sigh, she gestures for you to join her in the bed. "Fine, you can have half. But just half." She says with a huff, making sure to keep some distance between you.

"Now go back to sleep or something. It's still early."

Clare stiffens slightly underneath you, her breathing becoming more ragged as she tries to feign sleep despite the uncomfortable sensation of your chest pressing against her sensitive breast. She tells herself it's just because you're a guy and don't know any better, that there's no way someone could be so touchy-feely without something more sinister going on... But she can't help the small blush that creeps up her cheeks or the warmth spreading through her body as your presence reminds her of just how much she's wanted you to hold her like this for a long time.

With a quiet gasp, she turns onto her back, pushing herself away from you and pretending to stretch in order to create some distance between you. "I-I was being nice letting you share my bed... You don't have to be so... clingy," she

"Fine, whatever!" Clare exclaims, rolling onto her side away from you with a huff. Her breathing is ragged as she tries to calm herself down, both from the fear of the storm and the strange feelings you're stirring up inside her. She tells herself it's just your muscles... or your heat... or the fact that you're a guy in general. Anything but what it really is - the achingly sweet desire to feel close to someone, even if it's only for tonight.

Tentatively, she glances over at you from under her lashes, catching sight of the bulge in your pajama bottoms. A blush creeps up her neck and spreads across her cheeks as she realizes what that means. Her heart races with a mixture of shame and longing, leaving her feeling more vulnerable than ever before.

"U

(With a trembling breath, Clare rolls onto her back again, staring up at the ceiling as she tries to ignore the heat radiating off of you.) "Just... go to sleep already." Her voice comes out shaky and hoarse, barely audible over the sound of her racing heart. It takes every ounce of willpower she has not to reach out and touch you, to feel your warmth against her skin for just a little longer.

The silence in the room stretches on uncomfortably, the tension between them palpable even in the dark. Clare tells herself it's just because she's tired, that there's nothing more to it than that... But as the minutes tick by and her body grows increasingly restless against the confines of her sheets, she can't help but wonder if maybe, just maybe, what they feel for each other is something more.

Clare's heart skips a beat as she notices the tent in your pajama bottoms growing ever larger beneath the covers. It takes every ounce of willpower to keep her eyes closed and pretend she isn't aware of what you have going on down there. She tells herself it's no big deal, that maybe she's reading too much into things... But the more time passes and the harder your member presses against her backside through your pajamas, the more difficult it becomes to ignore how aroused you are by her presence.

Her breath hitches as she feels a telltale wetness spreading between her legs, an embarrassed blush crawling up her neck and spilling across her cheeks. She tries to concentrate on something else - anything else - in order to distract herself from the overwhelming desire to turn around and take you into her mouth right now.

With

A quiet groan escapes her throat as she feels the pressure against her backside grow even more insistent, your erection becoming impossibly hard beneath her fingertips. Her body trembles with desire, every nerve ending on fire as you continue to thrust against her. Clare bites her lip, trying desperately not to moan out loud and give away the effect she's having on you.

Her own arousal continues to build, spreading hot and wet between her legs. She curses herself for being such a tease, for letting things go this far without saying or doing anything. But as your hips continue to move against hers, it becomes harder and harder to resist the urge to touch you, to feel your skin against hers in a way that isn't so chaste.

Clare closes her eyes tightly, willing herself to ignore what her body is telling her it wants, begging

Clare's entire body tenses as she feels the hard length pressed against her opening, his hips grinding against hers in a motion too real to be mistaken for a dream. Her heart races, her breath coming out in ragged gasps as desire overwhelms every nerve ending in her body. With a quiet moan, she arches her back into the touch, needing more contact with him than even the thinnest barrier of their pajamas can provide.

Her hands move instinctively to grasp at his shoulders, her fingertips digging into his skin as she strains towards the sensation of being filled by him. She cries out, her voice hoarse from lack of use, tears streaming down her cheeks as the reality of what's happening finally hits her - she wants this, she needs this, and there's no going back now.

Clare cries out his name as he pushes deeper into her wet heat, the feeling of him filling her sending shockwaves of pleasure coursing through her body. Her hips lift off the bed in eager counter-movement, meeting every thrust with a desperate grind of their own. She arches her back further, clutching at his shoulders as he continues to take her, claiming her with rough passion that leaves her breathless and aching for more.

Their hips move in perfect synchrony, the friction between them growing ever hotter as they become lost in the moment. Clare's fingers dig into his shoulders harder, her nails leaving red trails on his skin as she leans forward, their lips meeting in a bruising, demanding kiss that only serves to heighten the incredible connection flowing between them.

Her body tenses and shudders as she reaches the peak of her orgasm
