It was a luxurious penthouse apartment.
Beyond the massive floor-to-ceiling windows stretched an expansive view, as if the entire city lay prostrate beneath this apartment.
The air carried the faint scent of high-end wood aromatics.
Every piece of furniture, every decoration—from the sleek leather sofa that obviously cost a fortune, to the abstract painting on the wall that she couldn't understand but felt must be impressive—radiated an aura of wealth.
This left Nijika feeling somewhat at a loss.
As if she'd entered an alien world.
"Have a seat." Seiji removed his jacket and casually tossed it on the sofa, his manner relaxed.
"Excuse me..." Nijika sat down stiffly.
Seiji then walked to the apartment's built-in bar and poured two glasses of amber liquid.
"What would you like to drink? Bourbon or Scotch whisky?"
"I... I don't really drink..." Nijika said nervously.
"Fair enough." Seiji smiled, casually downing one glass in a single gulp.
He then retrieved a bottle of chilled orange juice from the refrigerator and handed it to her. "Then have this."
Nijika awkwardly accepted the juice, thanking him softly: "Thank you."
Seiji wasn't in a hurry to get to the main event.
He leaned against the bar, his gaze playful, like a hunter slowly savoring the prey about to enter his mouth.
On the sofa.
Nijika kept her head down, nervous and shy.
The girl's cheeks flushed from tension.
From anxiety, her fingers kept fidgeting with the hem of her clothes, wrinkling her skirt.
"So cute..."
An enormous sense of satisfaction welled up in Seiji's heart.
Someone like Seika required violently shattering her hard shell to taste the softness within. That conquest was the thrill of storming a fortress.
But Nijika was a peach that, through her own kindness and purity, had washed and peeled herself clean, then carefully presented herself to him with trembling hands. Tasting her was the pleasure of watching a sacrifice willingly walk to the altar.
The two offered distinctly different, exquisite flavors.
And now, he possessed both.
This pair of sisters with completely opposite personalities—both under his complete control.
Seiji's excitement reached its peak.
"Nijika-chan,"
Finally, Seiji spoke.
His voice was low and magnetic, like a lover's whisper. "Before we discuss STARRY's debt and the business plan behind it..."
He set down his glass and walked toward her step by step.
Each step seemed to land on Nijika's heart, making her heartbeat skip.
"I think we need to demonstrate some sincerity first."
He stood before her, looking down from above, a demonic curve playing at his lips.
"Can you understand that?"
"...Yes, I understand." Nijika's body stiffened, and she slowly nodded.
She closed her eyes, her long lashes trembling continuously.
She extended her pale fingers and began unbuttoning her shirt, one button at a time.
Her movements were clumsy, as if each tiny button weighed a thousand pounds.
Seiji watched with a smile, patiently waiting for the girl to remove her obstructing clothes and present herself before him.
"I..."
Being inexperienced, Nijika didn't know what to do.
She instinctively used her arms to cover herself, her slender legs pressed tightly together, shyly hiding her body.
"Leave the rest to me."
Seiji smiled and stepped forward, capturing her lips in a kiss while Nijika's eyes filled with panic.
A scorching kiss tinged with alcohol invaded her senses.
Nijika's mind went completely blank.
She dazedly followed Seiji's movements, guided to lower her defenses and accept the intruder's invasion.
Throughout the process—
Nijika tried hard to reciprocate.
Because this was part of the "transaction." It was the "price" she had to pay to save her sister and STARRY.
She felt she had to do this.
But the girl's blank cognition had no idea how to begin.
She could only let herself become like a blank sheet of music being explored, played at will by Seiji.
Unfamiliar notes coursed through her limbs, performing strange, trembling melodies that made her body shake uncontrollably.
A sensation she'd never experienced swept through her entire body, as if her very soul had been captured by this strange composition.
His hands explored every inch of her innocent body—cupping her small, firm breasts, teasing nipples that had never been touched by anyone else. His fingers trailed down her flat stomach, slipping between her trembling thighs.
"You're already wet, Nijika-chan," Seiji murmured against her ear as his fingers found her virgin pussy, already slick with nervous arousal. "Your body is more honest than you think."
"I-I'm not..." Nijika gasped, but her protest died as two fingers pushed inside her tight entrance, stretching her open.
The penetration made her cry out—a mix of discomfort and unexpected sensation. He worked her carefully, his thumb finding the sensitive bundle of nerves at her apex while his fingers curved inside her.
"Ah...!" Nijika's back arched involuntarily. The dual stimulation was overwhelming, sensations she'd never imagined flooding through her virgin body.
Seiji freed his cock from his pants—thick, hard, intimidating to the inexperienced girl. He positioned himself between her trembling thighs, the swollen head pressing against her wet entrance.
"This might hurt at first," he said, his voice surprisingly gentle. "But I promise you'll feel good soon."
With one slow, inexorable push, he buried himself inside her.
Accompanied by a suppressed cry like a mournful whimper, the girl's world was completely torn open by an irresistible force, filled entirely.
"Nngh!" Tears sprang to Nijika's eyes as her virginity was taken. The burning stretch, the feeling of being so impossibly full—it was too much.
But Seiji didn't give her time to adjust. He began moving, his cock sliding in and out of her newly-opened pussy with increasing rhythm. Each thrust sent shocks of pain mixed with growing pleasure through her core.
"That's it, Nijika-chan. You're taking me so well," he groaned, his pace increasing. The wet sounds of their coupling filled the room obscenely.
Nijika's cries shifted from pained to confused to—against her will—pleasured. Her body, responding to instincts she didn't understand, began meeting his thrusts.
"Fujiwara-sensei... I... something's..." Her words dissolved into moans as an unfamiliar tension coiled in her belly.
"Come for me, Nijika." His thumb pressed hard against her clit while he pounded into her. "Show me you're mine."
The combination shattered her. Nijika's first orgasm crashed through her like a tidal wave, her virgin pussy clamping down on his cock as she screamed.
Seiji thrust through her climax, then buried himself to the hilt with a groan. His cock pulsed inside her as he filled her with thick spurts of cum, marking her as his.
...
...
After what felt like an eternity, the storm that had swept through everything finally subsided.
Nijika lay completely drained of strength on the soft bed, unable to move even a finger.
Her consciousness still floated somewhere in mid-air, her body echoing with unfamiliar dull pain intertwined with a strange afterglow, leaving her mind in a haze.
Seiji gently embraced her from behind, resting his chin on her small shoulder, savoring the warmth and softness of the girl in his arms.
The evidence of their coupling leaked from between her thighs—his cum mixed with traces of her lost innocence staining the sheets.
"Now," he finally spoke after a while, "the first step of the transaction is complete."
In Nijika's ear, he whispered, "Tomorrow, I'll have the legal department settle all of 'STARRY's' debts, and invest 100 million yen as startup capital for its reopening."
"100 million?!"
Nijika jerked her head around in shock, certain she'd misheard.
"That's right. 100 million." Seiji leaned in and kissed her lips three times in quick succession.
Normally, Nijika would've blushed at such a gesture.
But right now, she couldn't think about that at all.
"That's... too much..." Nijika's brow furrowed in confusion.
She'd thought being able to clear tens of millions in debt would already be pushing it.
She never imagined Seiji would be this generous!
"What's wrong?" Seiji smiled, reaching out to pinch her lips, which had parted slightly in surprise. "Not enough?"
"No! Not at all!" Nijika shook her head frantically, her expression caught between laughter and tears.
She'd only given herself once...
And in exchange received what was (to her) an astronomical sum?
No matter how she calculated this "transaction," she was the one who came out ahead!
Once that thought took root, it surged through her mind like a flood breaking through a dam, instantly washing away what little shame and sorrow she'd felt over losing her "purity."
After a pause.
A bright, energetic smile bloomed across Nijika's face.
She sat up in bed, unconcerned as the blanket slipped from her body, and blinked at Seiji with a mischievous grin.
"Fujiwara-sensei, you really are such a good person!"
"Sure, it hurt a little at first, but afterward it was actually... pretty nice. I feel like I'm the one taking advantage of you! Hehe..."
Seiji froze for a moment.
His heart couldn't help but cheer—Nijika's really something else!
Truly the little angel of Shimokitazawa!
"Then let me let you take even more advantage!" Seiji decisively flipped over and pressed her down beneath him once more.
"Eh!?"
...
Late at night.
Nijika, utterly exhausted, barely managed to rinse her mouth before collapsing into his arms and falling fast asleep.
Seiji pulled out his phone and sent a text to Ryo Yamada.
[Seiji: The little bird has entered the nest. Nijika's even sweeter than I imagined!]
Soon, Ryo's reply came through.
[Ryo: Congrats on pulling an SSR. But Nijika's different from your other women—don't push her too hard.]
[Seiji: Don't worry, I wouldn't dream of it.]
[Ryo: Good. I haven't gotten to play with Nijika yet, so if you train her too well and make her lose that innocent charm, I'll never forgive you.]
[Seiji: ...Am I the one playing with women here, or are you?]
[Ryo: That's rock 'n' roll!]
...
A few days later, Nijika was once again summoned to Seiji's office.
This time, the girl's mood was completely different from before.
She was no longer bracing herself with grim determination.
Instead, she was filled with gratitude—toward her "heavenly benefactor."
In fact, on her way over.
Nijika had carefully considered what kind of "position" she should use today to "please" Seiji.
After all, it was 100 million yen!
She had to take the initiative if she wanted to show proper sincerity.
It aligned with the girl's simple values—"If someone pays you, you do the work." That was just common sense.
However, when she entered the office, she found that Seiji didn't immediately start pawing at her like she'd expected.
Instead, he smiled and handed her a document.
"This was put together by my company's planning department—a custom one-year development plan for 'Kessoku Band.'" Seiji said. "Take a look."
"Yes." Nijika accepted the file with a puzzled expression.
She opened to the first page, and the title left her stunned.
["Kessoku Band" First Mini Album – "Radiance" Production Plan]
["Kessoku Band" First National Livehouse Tour – "Searching for Our Light" Tour Proposal]
["Kessoku Band" Exclusive Variety Show – "Run! Rock Girls!" Planning Document]
...
Page after page.
Albums, tours, variety shows...
Everything listed here was the kind of top-tier resources any underground band could only dream of.
If they followed this plan.
Within a single year, they could go from an unknown rookie band to a first-rate regional act!
Nijika's hands began to tremble.
She felt like she wasn't holding a document—she was holding a glowing future.
"Fujiwara-sensei... these..." She looked up at him, her eyes filled with disbelief.
"Still calling me Fujiwara-sensei?" Seiji interrupted her.
Nijika's face flushed. She lowered her voice. "Sei... Seiji."
"That's better!" Seiji nodded with satisfaction, then explained: "This is just a small 'investment' I'm making in your band."
He walked over to her and tapped a finger on the document's cover.
"Last time, our 'transaction' was about 'STARRY.'"
"But this..."
His face wore a warm smile, yet his words dripped with devilish temptation.
"This is 'extra' support."
"Of course, since it's 'extra,' it requires 'extra' payment."
"Yes!" Nijika's eyes flashed with understanding, and she didn't resist at all. Instead, she smiled gently and said: "I'll do my absolute best to 'repay' you! Whatever you want, just tell me!"
She assumed Seiji would make even more outrageous, shameful demands.
But to her surprise.
Seiji just shook his head. "You don't need to be so tense, Nijika."
"I don't need you to 'pay it all off' at once."
His voice became especially gentle.
"You can take your time."
"Pay in installments."
"Each 'extra support'—like recording this album, booking the tour venues—can be exchanged for one session, or a few sessions, of your 'service.'"
"Wouldn't that be easier on you?"
Nijika stood there, stunned.
She stared at this man who was saying utterly shameless, indecent things—yet wearing an expression of gentle consideration on his face.
Her entire worldview shook.
You can do that?
He could clearly just order me around however he wants. I even said I wouldn't refuse.
But instead, he's using this "negotiation" approach to lock me into a long-term "contract"...
Seiji is so kind!
In an instant, a thick filter clouded Nijika's judgment.
"Thank you so much, Seiji!" She broke into a radiant smile. "If I can pay it back gradually, that really does make things easier for me."
"But don't worry!"
"I won't slack off! Every single time, I'll give it my all!"
Nijika patted her flat chest solemnly, making a firm promise.
Seiji couldn't help but find it amusing.
"By the way, can I ask you for one favor?" Nijika's expression suddenly turned hesitant.
"What is it?"
"Um... could you please keep this a secret from my sister?" Nijika looked utterly serious.
Seiji's expression turned awkward.
Your sister?
She sold herself to me before you did.
"Don't worry, I won't put you in a difficult position." Seiji kept his answer vague, then—before Nijika could react—he leaned down and kissed her.
"Nijika..."
"To celebrate us reaching this 'long-term partnership,' why don't we start your first 'payment' right now?"
Nijika didn't hesitate for even a second. Smiling, she stood on her tiptoes and kissed him back.
It was a kiss filled with gratitude.
In front of the massive floor-to-ceiling windows of the president's office.
The girl's inexperienced, clumsy body did its best to meet the man's advances.
Though still shy, there was no resistance or struggle.
The girl cooperated gently and patiently with every request Seiji made.
Those eyes, normally bright as the sun, were now veiled with a touching mist. Her face flushed red as she gazed up—half resentful, half entranced—at the man who moved freely atop her.
...
A long while later.
When everything was over.
Nijika lay there with her body exposed, exhausted and sore, quietly tidying up both her own clothes and Seiji's.
Seiji watched her with great interest.
"Nijika, what are you doing?"
"Hm?" Nijika looked back at him in confusion, her face showing a matter-of-fact expression. "I'm cleaning up for you."
Suddenly, something seemed to occur to her, and her eyes lit up.
"Oh, right! Fuj... Seiji!"
The girl's face filled with anticipation. "I'm really good at cooking! And I'm great at housework too! So from now on, why don't I take care of your meals and cleaning at home?"
"Just think of it as... extra 'interest.' How about that?"
How could Seiji possibly refuse?
He waved his hand decisively and laughed. "Sure. Then from now on, you're my exclusive maid."
"Exclusive maid, huh... that sounds kinda dirty." Nijika blinked, looking both troubled and bewildered.
"An 'exclusive maid' is exclusive precisely because she's the 'sexy exclusive' kind." Seiji twisted the meaning of the words with a completely straight face.
"Don't corrupt the Japanese language!"
"Anyway, just know your mission, Nijika the maid!"
"Yes, yes, yes..."
That very evening.
Nijika put on a maid outfit and prepared dinner for Seiji.
During that time, she received a text from Ryo Yamada.
[Ryo: Captain, where are you? You're going to be late for practice.]
Nijika looked at her phone, her expression guilty and apologetic.
She knew about Ryo Yamada's relationship with Seiji, and felt like a thief—"stealing" time that should've belonged to Ryo and Seiji.
She quickly typed back:
[Nijika: Sorry, Ryo! I've got something going on today—I'll be there a bit later!]
...
Meanwhile, on the other end.
After receiving the text, Ryo Yamada's lips curled into a smirk.
"Hehe... Nijika..." The corner of her mouth lifted into a knowing smile. "Looks like you didn't just sell yourself—you threw in after-sales service too, huh?"
"Seiji's gonna be over the moon!"
...
Morning.
The air was filled with the rich aroma of freshly ground coffee and the sizzling sound of breakfast cooking in the warm morning sun.
Nijika stood in the kitchen wearing an apron, humming an unfamiliar tune while skillfully frying eggs.
Her older sister was hopeless at housework, and running the business drained all her energy.
So all the household chores fell to Nijika.
Preparing breakfast was nothing.
"Almost done. Time to wake up Ryo and Seiji..." Nijika glanced at the clock and murmured to herself.
This was Ryo Yamada's house.
It had been a week since that initial "transaction."
Nijika had perfectly adapted to her new role.
Seiji's exclusive maid—the sexy exclusive kind.
Of course, all of this was carried out under Ryo Yamada's cover.
Every day after school, she'd use the excuse of "discussing band stuff with Ryo" to hide the truth from her sister and PA-san, then come here.
At first, it was awkward.
Because Ryo always watched her with an amused expression as she fulfilled her "maid duties."
Several times, Ryo even joined in midway, teaming up with Seiji to tease her.
It made Nijika so embarrassed she wanted to whack both of them over the head with her drumsticks.
But gradually, she got used to it.
Now.
Even if she had to serve both of them at the same time, Nijika would only feel a little shy—not angry.
"Human adaptability really is amazing." Nijika reflected on everything and couldn't help but sigh.
With that, she finished preparing breakfast, turned, and headed toward the bedroom to wake the two still-sleeping occupants.
...
Eriri and Utaha had already moved out.
They could tolerate living in Seiji's house, but they refused to live in the house of one of Seiji's women.
It made them feel like they'd been demoted.
Especially since...
Utaha-san had been officially designated as the "head wife," which made her all the more determined to move out.
And Seiji, being ridiculously wealthy, simply bought each of them their own place.
As for Nijika—
She didn't mind living at Ryo Yamada's house. In fact, having Ryo around made it easier to cover for her.
As she stood there lost in thought...
A pair of strong arms suddenly wrapped around the girl's slender waist from behind.
A broad chest pressed tightly against her back.
"Kya!"
Nijika jumped in surprise, then realized it was Seiji. She turned her head with a helpless, bashful glare at the man behind her.
Seiji had just finished showering. He wore nothing but a towel around his waist, revealing his powerful abs. Water still dripped from his damp hair.
He rested his chin on Nijika's shoulder.
"What are you doing?" Seiji asked lazily.
"Making breakfast for you, Fujiwara-sensei." Nijika sighed in exasperation. "Please go get dressed—you'll catch a cold."
When the girl was annoyed or slightly upset, she would deliberately use formal speech with Seiji.
Seiji just smiled, ignoring her "protest." Instead, he lowered his head and kissed her cute earlobe.
Nijika's face instantly flushed bright red.
She turned around, glaring at Seiji with flustered indignation.
"Cut it out! We're going to be late for school!" she scolded, her soft voice carrying absolutely zero threat.
Seiji didn't care one bit. His hands slid under her apron, roaming across her bare skin.
"Haah..."
The girl could only sigh in resignation, arching her back slightly and pushing her chest forward—making it easier for his hands to cup and squeeze.
"Mmn..."
A soft whimper escaped her lips as his fingers found her nipples, teasing and rolling them between his fingertips.
"S-Seiji... the eggs are going to burn..." she protested weakly, even as her body trembled under his touch.
"Then turn off the stove," he murmured against her ear, his breath hot on her neck.
Nijika obediently reached over and switched off the burner, her hand shaking slightly.
The moment she did, Seiji spun her around to face him. Before she could react, his lips descended on her neck, sucking hard at the delicate skin just below her collarbone.
"Ahh...! N-Not there... it'll leave a mark..."
But Seiji ignored her protests, his mouth working insistently against her flesh while his hands continued kneading her breasts beneath the apron.
"Hnn... ah... Seiji..."
By the time he finally pulled back, a vivid red mark had bloomed on her pale skin.
Nijika looked down at it, her face flushed with a mixture of embarrassment and lingering arousal.
"How am I supposed to hide this?" she pouted.
"Wear something with a higher collar." Seiji smirked, lifting her onto the kitchen counter. "Now then... we still have some time before school."
"We really don't—mmph!"
Her protest was swallowed by his kiss as he pressed himself between her legs.
...
...
...
After school.
Nijika would occasionally come to STARRY to help out with work.
After all, if she never showed up, it would raise suspicions.
But she didn't notice—
In the corner, PA-san's gaze had frozen on her, an expression of utter disbelief spreading across her face.
"Is that..."
PA-san stared fixedly at Nijika's figure.
Her eyes locked onto a patch of pale skin peeking out from Nijika's collar as the girl bent over to wipe down a table.
There, just below the girl's collarbone, was unmistakably... a faint mark.
As Seiji's regular friend-with-benefits, PA-san was extremely experienced. There was no way she could be mistaken.
That's right!
That was...
A hickey!
Tidal waves of shock crashed through PA-san's mind.
N-No way... right?!
She instantly recalled how, just a few days ago, she'd been gloating to herself that after Seiji had gotten his hands on Seika, he wouldn't have any chance to make a move on Nijika.
And yet... it had only been a few days?!
Seiji had gotten Nijika too?
How did he even manage that?! Right under Seika's nose, pulling off something like this!
Thoughts raced through PA-san's mind, her expression shifting constantly.
Wait!
That's not the point! The point is...
PA-san suddenly realized something. She carefully glanced toward the bar counter, where Seika remained completely oblivious.
Gulp—
PA-san swallowed nervously.
In her mind, she conjured up an apocalyptic nightmare scenario:
—One day, Seika accidentally discovers the "marks" on Nijika's body. Under her interrogation, Nijika tearfully confesses everything.
—Then, Seika explodes with rage, transforming back into the violent delinquent she was in her student days, grabbing her bass guitar and storming out of STARRY to bash Seiji's head in!
And herself—as Seiji's side piece who had spoken well of him—
She would definitely get caught in Seika's fury and have her head bashed in too!
No! Absolutely not!
Waves of panic surged through PA-san's heart. This epic-level landmine absolutely could not be allowed to explode!
At least...
It couldn't explode on her watch!
