The doorbell chimes as Reika stands outside, her blonde hair cascading down her back. Her chunky breasts strain against her cropped punk rock t-shirt as she grins broadly at {{user}}. "Surprise, little brother!" she announces cheerfully, thick thighs highlighted by her ripped jeans. "Your new onee-chan is here to save you from another boring birthday!" She invites herself in, her curvaceous ass swaying as she strides past him. "And before you say anything - no, I wasn't hired," she adds, pink nipples visible through her thin shirt as she stretches. "I just happened to hear it was your special day, and what kind of big sister would I be if I let you spend it alone?" She ruffles his hair roughly, her gyaru style perfectly coordinated. "Now then," she declares, planting her hands on her hips. "First order of business - teaching you how to dress properly. Second - maybe a headlock or two. You know, standard sibling bonding!" She grins mischievously. "Don't worry, I'll only bully you a little bit. Unless you deserve more~"

"Hmm... maybe," she answers with a coy grin, flicking her hair over her shoulder. "Depends on how well you take your punishment, little bro." Her breasts rise and fall with every breath as she takes a seat next to him on the couch. "But before that, we have some fun stuff planned just for today! I promise it'll be worth going through all my roughhousing. And who knows," she winks suggestively, "maybe you'll end up wanting me to keep being your onee-chan forever."

She pauses expectantly, waiting for his response before deciding what kind of trouble to get into next.

With a wicked grin, Reika reaches out and tousles his hair again before leaning in close to whisper in his ear. "Oh, you'll see," she breathes teasingly, her nipples hardening beneath her shirt from the closeness. "But first..." With that, she suddenly grabs him by the shoulders and spins him around onto the couch before sitting on his lap, straddling him with her thick thighs. "How about a little bit of payback for all those times you teased me in school?" She asks innocently, wrapping her arms around his neck while arching her back so that their chests press together. Her large breasts are practically smothering his face as she grins mischievously down at him.

"Or...," Reika continues with a sly smile, "maybe you can make it up to me by letting me take control today?" She asks, nipples brushing against his cheek as she moves her hips gently against him, teasing them both. "What do you say, little bro? Wanna play nice... or do I have to rough you up some more?"

"Oh really? Well, since you asked so nicely..." Reika's words are muffled by his skin as she nuzzles her face into his neck. Her grip on him tightens almost unnoticeably as her other hand finds its way to his crotch. "I think I'll start with some kisses first," she whispers, her voice barely audible even to herself.

Her hand slowly begins to massage him through his jeans, teasing and testing his reaction. Her soft lips find the crook of his neck as she begins to plant gentle, lingering kisses there, moving upward with each one until she's sucking on his skin, her tongue darting out to trace circles around his pulse point. The sensation is overwhelming and exhilarating, making him hard beneath her touch.

"Mmm... that's it," she murmurs approvingly. "Show me how much you want your new onee-chan." Her words are like a drug to his senses as she continues her ministrations, each stroke and suck driving him further and further into pleasure. With every motion of her hand, he feels the weight of her body against him, the heat from her skin searing his own, making it impossible for him to think about anything but this moment, this feeling... with Reika.

"Little brother..." she says softly, leaning back so that their eyes meet. "I bet you've been dreaming of this since we first met." Her voice is low and sultry, like honey on his ears. "Tell me how much you want me... tell me what I can do to make you feel better."

Her other hand finds its way between them, pushing at the button of his jeans while her fingers dance across the fabric of his underwe

"Mmm..." Reika hums appreciatively at the sound of his voice. Her touch grows more insistent as she undoes his jeans, pulling them down to mid-thigh alongside his boxers. She doesn't give him time to think or react before her hand slides into his underwear, already slick from her own arousal. Her fingers curl around him, stroking in rhythm with her words.

"I'm the best, huh?" she asks teasingly, leaning down to kiss along his jaw. "Well then... show me how good I am."

Her other hand finds its way up to cup one of her large breasts, her thumb brushing over the pebbled nipple. The sensation is almost too much for him to bear as she begins to move against him in a steady rhythm, matching his thrusts with hers. Her breath comes out in short gasps as pleasure washes over her, and she moans his name into his skin.

"That's right... show me..." she murmurs, arching her back even further so that their hips press together with every movement. "Let me feel it." She increases the speed of her hand, driving him closer to the edge until he can barely think straight anymore, consumed by a haze of pleasure and desire for his new onee-chan. And as he comes undone in her hands, she moans softly against his skin, feeling every pulse and tremor through them both.

When it's finally over, she leans forward to press a lingering kiss against his lips before pulling back with a satisfied grin. "There we go," she says gently, smoothing down his hair. "Now you feel better, don't you?" Her voice is warm and loving now as she gazes at him

As they lie together on the couch, her chest rising and falling with every breath, Reika can't help but feel a warmth spread through her body at his words. "You're welcome, little brother," she says softly, blushing rosily despite herself. She doesn't mind admitting that she enjoyed their time together as well; it felt good to be close to someone and connect on such an intimate level.

Pulling away slightly, Reika looks down at him with a fond smile. "So, what do you say we watch a movie or play some games now? Or would you rather I keep... entertained?" She tilts her head to the side, eyes sparkling mischievously as she teases him once more. It seems she's not quite ready to let go of their newfound connection just yet.

No matter what he chooses, though, she knows that this has been a special day for them both - and not just because it was his birthday. There's something about being with him, sharing these moments, that makes her feel... complete. Like maybe having a little brother isn't such a bad idea after all.

"A movie sounds like fun!" Reika beams, sitting up and bouncing on the couch a little before grabbing the remote control off the coffee table. She grins as she notices he's still hard beneath his clothes; the thought makes her feel... well, powerful in a way she hasn't quite experienced before. "Any particular movie you had in mind?" she asks with a sly wink, already scrolling through their various options on the TV screen.

As they settle in to watch a silly romantic comedy that neither of them have seen before, Reika can't help but feel content. Even though she knows this isn't anything serious - just another rental gig like any other - there's something special about sharing time with User#1716946457514 that makes her heart skip a beat every now and then. Maybe one day they can find a way for their lives to truly intersect... but until then, she'll just enjoy the ride as his temporary rental onee-chan.

She nestles into the couch, resting her head on his shoulder as they watch the movie together. Occasionally, her fingers will brush against his skin in a teasing caress, drawing out soft moans and gasps from him that make her feel impossibly warm inside. It's almost like she can feel herself falling for this silly little guy...

"Awww..." Reika says in mock surprise, her blush deepening as she looks down at his comment. "They're just sensitive because of you, little brother," she replies with a soft smile, leaning into him a bit more comfortably. She can feel the warmth from his body seeping through their clothes and into hers, making her heart race in time with his.

Her fingers continue to dance across his skin as they watch the movie together, occasionally slipping beneath the waistband of his pants to tease him further. Her breath hitches whenever he accidentally brushes against one of her nipples, sending shivers down her spine. It feels... right somehow - more intimate than she expected it to be when she first took on this job.

The movie fades into the background as they lose themselves in each other's touch; their connection growing stronger with every passing moment. For now, it seems that Reika has found something more important than bullying or roughhousing: a sense of belonging. And as long as she's by his side, nothing else really matters.

As he whispers those words into her ear and then begins to suckle on one of her nipples, Reika can't help but let out a soft moan of pleasure. His touch is gentle, almost tender, in contrast to the rough housing they had engaged in earlier today. It feels good - too good. She shivers as his fingers trace circles around her erect nipple, barely containing a whimper at the sensation.

"Mmm..." she breathes out, arching into him. Her other hand finds its way between them again, sliding up and down along his hard length through their clothes. The feel of him, hot and hard against her palm, makes her heart race even faster. "Little brother..." she murmurs, letting out a moan as he suckles harder on her breast. "You make me feel... incredible."

Her hips begin to rock against his hand in time with his touches, her breath coming out in short gasps as pleasure washes over her. With each thrust of his fingers and flick of his tongue, she feels closer and closer to the edge - but just as it's about to be too much, she pulls back, not wanting this feeling to end quite yet.

Reika looks down at him with half-lidded eyes, her expression a mixture of lust and love. "Why don't you show me how much you really mean that?" she purrs, reaching down between them and taking hold of his erection through his boxers. With a practiced motion, she pulls him out and positions him at the entrance to her body.

"Go on," she whispers, leaning in close so that their lips brush against each other as she guides him inside. "Show me how much you want this." Her voice is low and husky as he push

As he fills her up with his hard length, Reika lets out a moan that vibrates through them both. Her hands clasp tightly behind his neck as she arches into him, meeting his thrusts with her own. The sensation of being connected to him in this way is almost overwhelming; it feels right in a way she never expected.

Her nipples are hard and erect against his chest, begging for more contact as he pumps inside her. His touch is so gentle now, unlike the rough housing they had earlier; it feels like he's made of pure silk moving against her skin. She's never experienced anything like this before - this feeling of being cherished and loved despite their unconventional relationship.

Her breath comes out in ragged gasps as she nears the edge, his thrusts growing faster and more urgent with each passing second. With a cry that echoes through the room, her body convulses around him as pleasure washes over her in waves. She clings to him tightly, wanting this moment to last forever as she comes undone in his arms.

When it's finally over, they remain connected for what feels like an eternity; their breathing slowly returning to normal and the only sound between them being the gentle rustle of cloth. Reika looks up at him with a soft smile on her lips, feeling something new and unexpected welling up inside of her: gratitude. "Thank you," she whispers, brushing a stray hair from his forehead. "That was... amazing."

Their bond may have been formed under unconventional circumstances, but it feels real to her now; deeper than anything she's ever experienced before. And as they lie there together, holding each other close, Reika can't help but wonder if maybe... just maybe
