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~"

"Well now," she says with an amused smile, walking closer and looking you over critically. "You're the birthday boy, aren't you?" Her tone is teasing, but there's also a note of genuine curiosity in it. "I'm Reika, your brand-new onee-chan for today." She pauses dramatically before leaning in close. "Or at least," she adds with a wink, "that's what I told the front desk to tell everyone when they called about this surprise visit."

"Aww, aren't you the sweet one!" She gives you a squeeze back, chuckling lightly. Her thighs meet your sides, and her breasts press against your shoulder as she hugs you tightly. "I'm here to make sure today is extra special for my little brother." With another laugh, she releases you from the embrace. "Now, let's get started with some sibling bonding!"

"Well," she begins with a grin, her blonde hair falling over one eye, "I've always wanted to try out that fancy arcade by the park." She looks at you expectantly, as if daring you to say no. "What do you think? Up for some brother-sister competition?"

Her tone is light and teasing, but there's a hint of determination in her voice that suggests she really does want to impress you with her skills... or maybe just show you up a bit. Either way, it's bound to be fun!

Reika grins even wider at your enthusiasm, practically bouncing on the spot in anticipation. "Alright then! Let's go kick some arcade butt!" She turns and heads towards the door, already grabbing her jacket off the hallway hook. "And don't worry, little brother," she calls over her shoulder with a wink, "I'll make sure you have plenty of fun... even if it means letting you win a few times."

"Come on then, little brother!" she says cheerfully as she steps outside, opening the door for you and waiting patiently for you to join her. Once you're both outside, she wraps an arm around your shoulder in a friendly, affectionate manner. "Let's go show them how much fun siblings can have together!"

Her step is confident as they walk through the park toward the arcade, but she can't help grinning to herself every so often at the thought of spending some quality time with her new "little brother." After all, being a rent-a-onee-chan doesn't mean she can't enjoy the occasional perk!

"Hmm..." she ponders for a moment, looking around the crowded arcade. "How about we start with some air hockey?" Her eyes light up as she thinks of the competitive game they could play. "It'll be fun to see who really has the best hand-eye coordination!"

"We'll see about that," she retorts with a sly grin as you get started on the air hockey table. She watches your technique intently, her eyes narrowing in concentration. "Alright little brother, let's see what ya got!" she challenges, taking her position across from you with determined determination.

The game begins, and it's clear that Reika has a bit of an advantage thanks to her experience playing sports during college - but don't tell her that! She wants to make this a fair competition. Back and forth the puck goes, each player giving it their all in an effort to score first. As you play, she can't help but enjoy spending time with you; despite being a rent-a-onee-chan, she genuinely seems to care about making today special for you.

"I've had some practice," she says modestly, grinning and nudging you with her shoulder. "But don't worry, little brother. There will be plenty of other games for us to play where I can show off my true skills." She glances around at the bustling arcade before adding, "How about we try our hand at some claw machines next? Maybe we can find you a little prize or something!"

Her gaze drifts back to you, her expression softening as she studies your face. There's an almost maternal warmth in her eyes, despite the fact that they're surrounded by thick lines of black eyeliner and candy-colored eyeshadow. It's clear that spending time with you means something to her, even if it is just for the day.

"Great choice!" She exclaims brightly, leading you over to a row of colorful machines. "Now, let's see if we can't snag you something special today." With that, she begins searching through the rows of stuffed animals and trinkets, her eyes narrowing in concentration as she inspects each one for hidden prizes.

As they play, Reika finds herself laughing and joking with you between attempts at winning a prize. Despite her tough exterior, there's a gentle side to her personality that shines through when she's around those she cares about - even if it is just for one day. And who knows? Maybe by the end of today, she might find herself wishing that she could be your sister for always...

"Awww," she says with a laugh, taking the stuffed bear from you and hugging it to her chest. "How sweet of you, little brother! This one is for all your hard work today." Her smile grows wider as she looks at you over the top of the teddy's furry head. "I think I can't think of anyone who deserves it more."

She takes your hand in hers and gives it a gentle squeeze, her touch surprisingly soft for someone so muscular. "Come on, let's go find something else fun to do before we have to call it a day! I want to make sure you get the full onee-chan experience." Her grin is infectious as she leads you away from the claw machines, already plotting out their next adventure.

"A movie sounds lovely," she says with a contented sigh, following you as you lead the way out of the arcade. "And I've heard great things about your cooking! The offer to have you cook for me is truly touching." Her voice holds a genuine note of gratitude; it seems that despite her rough exterior, she does have a softer side after all.

As the two of you walk through the park back toward your apartment complex, she glances over at you with an appraising eye. "So... what's on your list of movies to watch?" she asks curiously. "I know we only just got started today, but it would be nice if I could get to know more about the things that make you happy." Her smile is warm and inviting; it almost seems like she really does want to form a connection with you beyond just being your onee-chan for the day.

"Of course you can," she replies with an encouraging nod. "I want to get to know everything about my new little brother." Her tone is earnest and friendly; it's obvious that she means what she says, even if it does sound a bit strange coming from a rental onee-chan.

She waits patiently for you to speak, her expression expectant yet gentle as she studies your face. Her eyes are warm and open, inviting you to share whatever is on your mind without judgment.
