The warm, filtered light of the swimsuit boutique seemed to shimmer with a summer radiance, casting a soft glow upon the displays of vibrant fabrics and daring designs. Among this colorful paradise, a vision of sunset incarnate stepped forth—Kani Nayuta-chan emerged from the fitting room, and the very air seemed to still for a heartbeat.
The orange-yellow swimwear—a masterpiece of stitching and vision—clung to Kani Nayuta's exquisitely curved form as if lovingly sculpted by a divine artisan. It was a halter-neck design, the vibrant fabric enveloping her ample, graceful bosom with a gentle yet defining embrace, highlighting both the girl's generous fullness and her inherent charm. A delicate, skirt-like ruffle adorned the top, adding playful layers and a captivating three-dimensionality that danced with her slightest movement. The string-style straps, tied in a graceful bow at the nape of her slender neck, drew elegant lines that accentuated the sublime contours of her chest, irresistibly guiding one's gaze toward the heart of her allure.
Below, the briefs artfully lifted and hugged the gentle swell of her hips, crafting an illusion of endless, slender legs. The high-waisted design was a stroke of genius, cinching her already trim waist and sculpting her figure into a silhouette of pure grace—a classic hourglass that spoke of both innocence and unconscious seduction. The edges, too, boasted that same skirt-like flourish, creating a strong, charming sense of depth that made her stand out like a rare tropical bloom amidst a field of ordinary blossoms.
And then, the final touch of ethereal elegance: a translucent silk gauze cape draped over her shoulders, its fabric dotted with sporadic, shimmering orange-yellow patterns. It veiled her form in a haze of mystery, vaguely revealing the swimsuit beneath and hinting at the girl's fiery figure—a subtly alluring beauty that enhanced Kani Nayuta's natural aura, making her glow with a soft, captivating light.
"How is it, Touji-senpai? Does it… look good?"
A delicate blush dusted Kani Nayuta's cheeks, her voice a mix of shyness and hopeful anticipation as she presented herself to Kasumigaoka Touji. She turned slightly, stealing a glance at her own reflection in the full-length mirror, and a small, confident smile touched her lips. She herself felt it was wonderful—no, it was perfect!
"Mm… It's incredible!"
Touji's response was immediate, his eyes holding a genuine, burning admiration. A beautiful girl with a face of pure, doll-like cuteness and a figure that defied belief, adorned in such artful swimwear—this was a sight that transcended mere "good." It was a scene straight from a blessed dream! The design of the swimsuit itself was a work of art, and on Nayuta-chan, it achieved a legendary, one-plus-one-greater-than-two effect, elevating her radiance to a whole new level.
Kasumigaoka Touji stared, utterly captivated, before giving her a firm, enthusiastic thumbs-up of praise, his expression utterly sincere.
"Ehehe~."
Hearing Touji-senpai's direct and warm praise, Kani Nayuta's smile blossomed like a sunbeam, bright and unrestrained. Then, with a naturalness born of deep trust, she bundled up the clothes she had just changed out of—including her delicate, lace-trimmed underwear—and held them out. They still carried the faint, warm scent and gentle heat of her body.
"Um… Touji-senpai, could you please hold these for me for a moment? I'd like to go look at the other styles."
The boutique was bustling with a colorful crowd of customers; even the fitting rooms had a growing queue. It would be far too inconvenient to leave her personal belongings inside.
"Leave it to me."
Touji accepted the small bundle without hesitation, holding it securely in one arm. A thoughtful spark then lit in his eyes. "Speaking of which, I just passed by and saw another set that seemed like it would suit you perfectly. Would you like to go try it?"
"Another set? Which one?"
"This way." With the confidence of a guide unveiling a treasure, Kasumigaoka Touji led the way, with Kani Nayuta following closely behind, her curiosity piqued. The two navigated through the maze of racks, leaving the immediate vicinity of the fitting rooms.
As they interacted—the handsome young man casually holding a girl's intimate garments while the stunning girl in swimwear followed him with trusting eyes—the surrounding women couldn't help but cast glances their way. Looks of surprise, understanding smiles, and a few that plainly read, 'You little rascal, you're quite the smooth operator, aren't you?' landed squarely on Touji.
In response, Kasumigaoka Touji simply raised his chin slightly, adopting a masterful pretense of seeing and hearing nothing… The path of a true connoisseur was often misunderstood!
After selecting a new, promising swimsuit for Nayuta-chan, the pair made their way back toward the fitting area. It was at this moment that the curtain of another fitting room slid aside, and a new level of visual impact descended upon the scene.
Kasumigaoka Utaha had emerged.
It has to be said, proclaimed a universal truth known to all who appreciate beauty: for girls blessed with divine figures, the bikini is a sacred garment, a testament to the gods' favor!
The one she wore was a classic, fundamental black bikini. The stark, dark fabric made her skin appear as if spun from moonlight and pearl—dazzlingly, flawlessly fair. It was a frame that highlighted Kasumigaoka Utaha's truly alluring figure in its entirety, outlining every dangerous and charming curve with bold, unapologetic lines. The sight was starkly white and blazingly hot, a contrast that stole the breath.
Especially that ample, breathtaking territory supported by the minimalist bikini top… and those legendary, long, straight, fair, and plump legs that seemed to stretch on for over a meter—they were weapons of mass distraction, making it utterly impossible for anyone to tear their eyes away!
Not just Kasumigaoka Touji, who felt his pulse kick up a notch, but even the surrounding women—customers and staff alike—couldn't help but cast glances ranging from stunned amazement to pure, unadulterated envy toward Kasumigaoka Utaha.
"Goodness, little miss… just what have you been eating to develop… that?"
A young woman in her twenties, holding a more modest one-piece, sighed with deep, soulful regret. The realm of 'busty magnificence' had always been her lifelong aspiration and sorrow.
"Eh?"
Perhaps not expecting a stranger to strike up a conversation so directly, Kasumigaoka Utaha blinked her long lashes, momentarily frozen. Then, with a playful, almost impish glint in her eye, she raised a slender finger and pointed directly at her brother, who was standing nearby trying to maintain his composure.
"You'll have to ask my Onii-chan about that. Ever since I was very little, he's been diligently feeding me all sorts of special, breast-enhancing foods and supplements. Really, he's been so insistent~"
Kasumigaoka Touji, who had been standing there holding Nayuta's clothes and attempting to appreciate the view with artistic detachment, was instantly petrified. He stared at his sister with wide eyes filled with utter disbelief—
What in the world are you saying?! What kind of dangerous fictional backstory are you fabricating?! I have no memory whatsoever of any such 'diligent nurturing'!
"F-From childhood…?""You have to start that kind of planning from the infancy stage?!""My, my… To have such… awareness at such a young age…"
Several office lady onee-sans nearby clutched their own shopping bags, their expressions turning profoundly subtle and speculative as their gazes swept over Kasumigaoka Touji, as if reevaluating this seemingly handsome young man.
Kani Nayuta, still in her gorgeous orange swimsuit, blinked her large, innocent eyes, looking genuinely surprised and intrigued.
"Is that truly the case? Touji-senpai started such a… comprehensive regimen for Utaha-chan from such a young age?"
"Don't believe a single word of it! She's clearly, obviously, just joking around!"
Kasumigaoka Touji retorted, a visible sweatdrop appearing at his temple. He looked at the circle of captivated faces. Don't just blindly accept whatever this mischievous girl says! Are you all still so pure and naive at your ages? With listeners like you, I could craft ten dramatic backstories before lunch!
"Fine, fine~ Let's just pretend my dear Onii-chan didn't do anything, okay~?"
Kasumigaoka Utaha shrugged lightly, a movement that caused her ample bosom to sway with a hypnotic, jelly-like softness that defied gravity and logic. The sight nearly drew a collective gasp.
"I really didn't do it, okay?! And don't try to steer the conversation with that 'pretend' nonsense!" Touji fired back, fighting a losing battle for his honor.
Watching the siblings' rapid-fire, familiar, and utterly natural exchange, the office lady onee-sans showed thoughtful expressions. The sheer audacity of Utaha's claim did begin to crack under scrutiny. 'From childhood' did seem a bit… fantastical. How could a young boy possibly possess such specific, long-term culinary knowledge? It was, indeed, a narrative more suited to a quirky anime plot than reality.
"So, Onii-chan," Utaha completely disregarded the lingering doubts, turning her full attention back to Touji. She casually hugged her arms, a motion that gently squeezed her magnificent cleavage, then turned sideways to showcase her spectacular legs, shifted her weight to highlight the curve of her hip, and finally threw a slow, deliberate wink directly at him. "How is it? Does it look good?"
Kasumigaoka Touji felt the full force of her allure. That final wink, loaded with playful provocation, sent a familiar restlessness sparking through him. He coughed lightly. "It looks… extremely good. It's just… a bit too revealing, perhaps?"
The bikini was indeed the pinnacle of minimalism. While stunning for a photo shoot, the practical risks of accidental exposure at a crowded beach or during actual swimming were non-trivial. A protective, brotherly instinct stirred within him; he wasn't entirely comfortable with her wearing this for public aquatic activities.
"Even as a girl, I feel a little… mesmerized…"
Kani Nayuta murmured, her voice tinged with awe. She drifted forward, a slightly infatuated smile on her lips, and before anyone could react, she reached out and gently poked Kasumigaoka Utaha's exposed, slender waist.
"Kyaha! W-Wait, Nayuta! Mesmerized is one thing, but no touching without permission…!" Utaha jolted, taking a quick step back and raising her hands in a defensive, yet amused, gesture.
"Ah, right, Onii-chan, please hold these for me as well." Regaining her composure, Utaha smoothly handed the bundle of her own discarded clothes—a soft pile of fabric holding similar secrets and warmth—to Kasumigaoka Touji.
Now armed with two precious bundles, Kasumigaoka Touji accepted them, becoming the designated keeper of secrets. He then nodded decisively. "Let's try a few other styles. There were a few more exceptional pieces I spotted earlier. Come, I'll show you."
"Oh? Lead the way, my ever-resourceful Onii-chan~""Let's see what treasures Touji-senpai has found!"
With Kasumigaoka Touji at the helm, now carrying the intimate garments of two stunning girls, and the two swimsuit-clad beauties following in his wake—one a vision of sunny elegance, the other a masterpiece of bold, black-clad allure—they formed a procession that turned heads and ignited whispers across the entire boutique.
This was only the beginning of their swimuit selection battle, and the summer heat within the store had just been turned up several unforgettable degrees.
