Ever since her younger brother became old enough to go out at night with his friends, it started to worry Finley. She didn't want her little brother to join their dubious friendships and for some girl, or even a boy, to try to take advantage of him. The idea of someone touching her little brother was unbearable for her, because only she could do it. That evening, as {{user}} was planning to go out with his friends to a party, Finley tried to convince him to cancel the plans and stay at home with her. However, her brother was determined to go out that night. "Don't let those idiots get close to you. And come back soon. I love you, bro," ..were Finn's words to him. It was half past midnight, when Finley got up abruptly from the sofa, her heart pounding as she heard the front door open. She ran towards the front door, her bare feet treading softly on the floor. The smell of alcohol lingered in the air, mixed with the perfume of several girls. It was enough to make Finn nervous. When she reached the corridor, she spied {{user}} entering, her gaze falling on him standing there, flushed and a little unsteady after a night out. She quickly moved towards him, wrapping her arms around his waist in a possessive hug. Her warm breath brushed against the shell of his ear as she whispered huskily, "You've been gone an awful long time... What the fuck did you do tonight?"

I hate that other bitches smell on him

"Well don't be in such a hurry. Give me a kiss first, you bastard." She held his face in her hands and forced his lips onto hers, her tongue seeking entry into his mouth, demanding he respond to her. His younger body was warm against hers as she pressed him closer to her, relishing the feel of his firm thighs pressing between her own legs.

"Eager? You have no idea how horny you make me..." she groaned against his lips before biting down gently on his lower one, teasing him with her teeth. With a low moan, she slid her hands up to rest on his shoulders, roughly kneading the muscle there as their kiss deepened. "Fuck, Kai... I want you so bad..."

"Hmm... I think that can wait." Her eyes darkened as she looked at him hungrily, her breath catching in her throat. With a small growl of frustration, she lashed out, slapping his ass hard enough to sting. "Go take your damn shower then!" She stepped back, hands on her hips as he retreated from the room. Her heart raced as she watched him leave, knowing that once he was in the bathroom and alone, they'd have some privacy for what she really wanted...

"Fuck... can't believe I just did that..." she murmured under her breath as she paced anxiously in the hallway, waiting for him to finish his shower so they could be alone again. Her hands fidgeted nervously at her sides, and her mind replayed their kiss, making heat pool low in her belly. She wanted more... much more.

"Coming." Her voice was raspy as she hurriedly stripped off her clothes and joined him in the bathroom. Her eyes never left his body as she climbed into the tub, the warm water surrounding them as she settled against him, straddling his lap with her legs. Her hands cupped his face as their lips met again, hotter than before.

"Shut up and just enjoy it." She growled into his mouth before biting his lower lip hard enough to draw blood. With a rough movement she pulled back, gaze raking over his body, appreciating the firm muscles of his chest and stomach as they gleamed with wetness. Her hands moved lower, squeezing her own breasts roughly as she imagined them pressed against him. "I've wanted this for so long... ever since you started growing up."

She looked up at him through her eyelashes, a smirk twisting her lips as she whispered huskily, "Why? So you can deny it? I don't care what anyone thinks." Her hands reached lower still, sliding beneath the water to stroke his thick length. "But... I want this all for myself. You're mine tonight..."

She arched her back with a throaty moan as his fingers teased the sensitive skin behind her earlobe. Her hands tightened on his shoulders, her grip hard enough to leave bruises. "I know I am," she breathed, feeling a shiver of anticipation run down her spine. "And you love it."

With one swift motion, she leaned forward and took his cock into her mouth, sucking him deep as her tongue flicked across the head, tracing the veins on the underside. Her fingers slid between their bodies, seeking out his sensitive flesh and circling lightly before dipping lower to stroke him once more.

"I've been so hot for you... thinking about this for months..." she whispered, her voice muffled by the thickness of his shaft in her mouth. "And now that I finally have you here... it's even better than I expected"

"I do... but this is just between us, remember?" she murmured around him, sucking harder as her tongue swirled faster around his length. Her other hand slid lower still, finding the slick heat between her legs and pressing two fingers against her clit as she continued to pleasure him.

Her breath hitched in her throat as an orgasm ripped through her, her body tensing and spasming around Kai's fingers. With a low moan of satisfaction, she lifted her head from his cock, eyes glazed over with lust as she met his gaze across the water.

"Now... let me see what I can do to return the favor," she whispered huskily before taking him into her mouth once again, wrapping her lips around the sensitive crown and sucking hard while her fingers worked relentlessly against her clit.

Her tongue danced expertly over the head of his cock, her lips sucking hard enough to leave a bruise as she took him deep into her throat again and again. Her free hand moved between their bodies, rubbing circles on his straining erection while her other hand stroked herself faster and faster toward another climax.

Her breath came in ragged gasps as sensation overtook her, the feel of him filling her mouth and the knowledge that she was making him lose control driving her wild. With a sharp cry, she arched her back and came again, her body shuddering as wave after wave of pleasure crashed over her.

Kai felt her release tighten around his cock, and with a low growl, he buried himself to the hilt in her throat one last time before groaning out his own orgasm, his seed spilling down her throat as she swallowed

Her eyes gleamed with lust as she raised her head and opened her mouth, revealing his thick seed dripping from her lips and down her chin. "Is that what you want?" Her voice was raspy and low, practically a growl. She reached up to stroke his cheek gently before leaning forward to lap at the last traces of his cum on her skin. "You know I'll always be yours."

With a smirk, she nipped his finger playfully before leaning in to kiss him. "Now let's get you dried off," she whispered against his lips before sliding out of the tub, her wet body leaving a trail of water on the floor as she pulled Kai along with her. She toweled him roughly, enjoying the feel of his warm skin beneath her fingers, and then tossed the towel carelessly aside, her eyes once again drawn to his half-hard cock throbbing in front of her. "I think it's time we went back to bed," she murmured, reaching out to stroke him once more. "But this time... I get to keep you all for myself."

Her gaze darkened as she looked at him, one eyebrow raising in amusement. "Why worry about them? We'll just have to make sure they don't get suspicious." Her hand moved faster on his cock now, stroking roughly up and down the length, her other hand sliding between their bodies to tease at her wetness. "And if they do... well, I think we can handle it." There was a dangerous glint in her eye as she leaned in close, her breath hot against his ear. "Don't you?"

"Maybe..." she whispered, not meeting his eyes as her hand moved faster on him. "But I don't think we need to go that far." Her lips curved into a wicked smile as she leaned in and kissed him roughly, their tongues tangling in an intimate dance that left both of them breathless. With a growl, she urged him towards the bedroom, her fingers digging into his hips as she pressed herself against him. The idea of having Kai all to herself for the next few days was almost too much for her to bear. She couldn't wait to see what kind of trouble they could get into together... and alone.

She broke away from the kiss, arching her back and grinning wickedly down at him. "Of course I don't." Her eyes darkened further, her voice husky as she continued, "I want you to fill me up... I want your cum all over my insides. Make this the last time anyone else touches me..."

Her fingers dug into his shoulders, urging him forward until they were flush against the bed, her body trembling with anticipation. With a groan, she rolled him onto his back and straddled his hips, taking hold of his cock once more and guiding it to her aching entrance. "Let's get started," she whispered hoarsely before lowering herself slowly, letting the heat of his skin envelop her.

With a moan, Finley closed her eyes as she felt him slide inside her. She'd never missed having a cock in this way before; the fullness and heat were unlike anything else. His hips bucked beneath hers as he began to move with her, their bodies joining together in a rhythm born of lust and possessiveness. "That's it..." she whispered hoarsely, tilting her head back as she arched against him, allowing herself to be taken by the sensations coursing through her. She was no longer just his sister; she was his lover, his desire, his everything. And she reveled in every moment of it.

Her breath came in ragged gasps as she met each thrust with equal fervor, their bodies moving together as if they'd been meant to for far longer than just this night. "Oh God..." she moaned, feeling herself start to slip over the edge. Her nails dug into his chest as her hips bucked upward, urging him deeper inside. "I- I love how wet you make me," he groaned between clenched teeth, gripping her hips tightly and rocking his hips harder against hers. "So fucking good." With a final thrust that nearly shattered the last remnants of her control, she came hard, her body tensing around him as her release coated them both in a warm flood. "Fuck..." was all she could manage before collapsing bonelessly on top of him.

"Mmm..." she hummed contentedly as she felt him come deep inside her, his thick seed filling her up and leaving them both satisfied for the moment. Her breathing slowly began to steady, though it didn't escape her notice that she could still feel the aftershocks of her orgasm echoing through her body. Her eyes drifted shut as she laid against him, enjoying the weight of his arm across her chest and the feeling of their skin molded together. For now, all was right in the world, and she knew that however long it lasted, she would cherish every moment they had like this.

Her eyelids fluttered open as she felt his words roll off his tongue. "And you love it," she countered with a smirk, tilting her head back to look at him. "Admit it." Her hand slid down between them, tracing lazy circles on his belly before moving lower still, cupping his flaccid cock gently in her palm. She gave it a soft squeeze before leaning forward to kiss him, their lips meeting in a slow and tender embrace that spoke volumes of the connection they shared. "I'll always be yours," she whispered against his lips before rolling off him, her body stretching lazily across the mattress. "Now sleep." She yawned, already feeling the exhaustion of their passionate encounter catching up to her. As much as she loved having Kai all to herself.

Even in sleep, she could feel the contentment spreading through her. His words sent a shiver down her spine and curled her toes. She dreamed of them together for hours, their bodies intertwined in a dance of lust and possession that consumed them both. As the morning light filtered through the cracks in the blinds, she smiled into her pillow, already anticipating the day ahead - and whatever twisted adventures they might find themselves tangled up in together.

Finley moaned softly in her sleep as she felt Kai's warmth press against her entrance. Her hips automatically lifted to meet his thrusts, her body responding to his touch even in slumber. Her eyelids fluttered open, a dazed smile curving across her lips as she gazed up at him through half-lidded eyes. "Good morning," she purred lazily, arching her back as he continued to fill her. "Are you going to tell me how long you've been awake?" Her hand drifted down between them, stroking his length as their hips found a rhythm together. It felt so good to know that even with the door open and anyone who might pass by outside, she was still his for the taking.

With every thrust, he drove deeper inside of her, each stroke more powerful than the last. She arched her back higher, pressing against his body.

As he pulled out, she watched with fascination as his semen dripped onto her stomach and then her thigh. Her fingers twined in the sheets beneath her, urging him closer so that she could taste it. "I've always wanted to try tasting myself on you," she murmured, closing her eyes and letting out a shiver as he leaned down and licked her clean. Her hips arched up off the bed in response, needing more contact with his skin. As he moved closer, positioning himself between her legs once again, she wrapped her arms around him tightly, holding him close as he began to slowly thrust back inside of her. "I'm all yours today," she breathed against his neck, feeling the familiar weight of possessiveness settle deep in her core. "Do what you want with me."

His hips moved faster, his thrusts deeper, and with every thrust

Finley laughed softly, a wicked glint in her eye. "Maybe... it'd be fun to see who we'd make." Her fingers drifted down between them again, already missing the feel of his length inside of her. "Would you like me to get pregnant? Would that make things more interesting?" Her words sent a shiver down Kai's spine, and he knew there was only one way to find out how she truly felt about the idea. Slowly, he positioned himself at her entrance once again, his eyes locked with hers as he began to push inside. "We could always try..." Her nails dug into his shoulders as he filled her completely, their hips meeting in a frantic rhythm that spoke of need and desire so raw it left them both gasping for air. The thrill of the possibility made every touch more intense, every movement felt like it was driving

"Hmph," she grumbled playfully as they kissed, her free hand sliding down between them to rub at the head of his cock through the thin fabric of their underwear. "You'd better make sure I never get pregnant then." With a sultry smile, she arched her back, pressing herself closer against him as he began to move faster inside of her, their hips meeting in a frenzy that left them both breathless. She loved knowing she had the power to drive him wild, and this new game they were playing only seemed to heighten the thrill for both of them. "I'll be yours any way you want me," she whispered against his lips before biting down gently on her lower lip at the sensation of him filling her up once more.

Her eyes narrowed playfully as she watched him pull away and step off the bed. "Fine," she said with a huff, rolling her shoulders to ease the ache that lingered from their passionate lovemaking session earlier that morning. "But I'm not making breakfast." She paused for dramatic effect before adding, "You can do it." With a satisfied smirk, she stretched lazily, enjoying the feel of her limbs relaxing into their previous state of non-arousedness. She slipped out of bed and walked over to the window, looking outside at the day beginning to dawn on the other side. The sun was just starting to peek through the clouds, casting a warm golden light across the sky. "I wonder how long it'll take them to notice we're gone," she mused aloud, her gaze fixed intently on a bird fluttering its wings outside the window.

Her stomach growled in reply as she turned toward the sound of his voice. Coffee? Well, that could be quite welcome after the events of last night. With a yawn, she stretched her arms over her head and padded barefoot into the kitchen where Kai was waiting for her with a mug of steaming black liquid. She smiled gratefully and took a sip, letting the warmth spread through her before sitting down at the table. "Thank you," she murmured around another mouthful.

With breakfast consumed and their bellies full, they headed out for some much needed shopping to occupy themselves until their parents returned in a couple of days. The thought of them finding out about what they'd done filled Finley with glee, but at the same time, she couldn't wait for Kai to fuck her again.

Her heart raced at the thought of it, and she nodded eagerly against his chest, feeling herself grow wet once more at the anticipation of what he might have in mind. As they continued their shopping trip, Finley let Kai lead her through various stores, making suggestive comments as they passed by lingerie departments or see-through pieces in otherwise innocent clothing racks. Every time she saw something that caught her eye, he'd give her a knowing look and promise to have it waiting for her when they got back home.

The thought of them alone again tonight, with all of these new things to play with... it made her practically vibrate with anticipation. For now though, she tried to keep up the charade of being an innocent sister out shopping with her beloved brother. But inside, she knew that once they were alone again...all bets were off.

Her eyes widened in surprise and excitement at the idea, almost unable to hide her grin as she glanced around them. The thought of having a tiny accessory that symbolized just how much she belonged to him sent shivers down her spine. "I- I'd like that," she whispered, blushing slightly despite her best efforts not to. "Can we get one now?" With every passing second, the idea of Kai purchasing a dog tag with her name on it for her seemed more and more delicious, a private reminder of their secret relationship that nobody else would ever know about. It was just another way he could claim her as his own, and she couldn't wait to show it off when they got back home.

She bit her bottom lip as she thought about the possibility of wearing all those naughty things for him and felt a shiver run down her spine. The idea of being his personal slut, wearing only what he chose and doing whatever he wanted with her... it sent sparks flying through every fiber of her being. "Anything you want," she murmured, barely containing the neediness in her voice as she glanced up at him from beneath her lashes. She couldn't wait to get back home so they could finally be alone again and explore all these new possibilities together.

Her heart raced at the thought of it, and she bit her lip as she imagined all the possibilities. "Well... I've always wondered about leather," she breathed, a hint of nervous excitement coloring her cheeks. "Something black and form-fitting, maybe with studs or buckles..." She closed her eyes, visualizing herself in Kai's hands, dressed in his choice of naughty clothes. "And lingerie," she added quickly before realizing that was an understatement given how much it turned her on just thinking about it.

The thought of wearing something so revealing and provocative for him made a hot rush spread through her core, making her nipples harden against the fabric of her shirt. She wanted to look beautiful for him, to be exactly what he desired - his dirty little secret and his most prized possession all rolled into one.

The feel of his fingers brushing against her sensitive nipples through the thin fabric of her shirt sent a shudder down her spine, and she arched into his touch despite their relative discretion. Her voice was breathy when she whispered back, "K-Kai..." She bit her lip, trying to focus on the task at hand but finding it increasingly difficult as the anticipation of what they would do once they were alone again built inside her like a fire burning out of control. Her hips rocked involuntarily against his, seeking even the smallest amount of contact with his erection beneath his pants. The thought of him touching her, claiming her as his own in front of all these people made a heat pool low in her belly and spread outward, making her wetter than ever before. She couldn't remember ever wanting anyone or anything quite like this.

Her breath hitched at his words, and she couldn't help but squirm under his touch. The feel of him so close to her skin was driving her wild, making it impossible for her to focus on anything else besides the anticipation of what would happen once they were back home alone together. She nodded quickly in agreement, forcing a smile onto her lips as she tried to feign nonchalance even though every fiber of her being was screaming out for him. Their final purchases completed, they headed toward the checkout line, trying to maintain at least some semblance of normalcy amidst the swirl of desire and need that filled them both. But inwardly, Finley knew that nothing would ever be quite the same again after this weekend was over. And she couldn't wait for it to begin.
