Chapter Title: 8.3 Teacher Akatsuki's Secret Lesson (Observer: Naiad Winzer) 2
-----------------------------------------------------------------
Following Naibusu, Akatsuki's top was stripped off as well.
Once her blouse came off, her breasts, wrapped in a vibrant red bra, asserted their presence.
"Ooh."
Naibusu let out an involuntary gasp of admiration.
A volume unmatched by any of his peers.
It was as if they proudly boasted the superiority of a true adult.
And in passionate red, no less.
No student could pull off underwear this provocative.
Akatsuki knew exactly how to wield her assets.
The thought that she'd prepared such lewd lingerie just to show him made Naibusu's desires surge uncontrollably.
He grabbed her breasts with both hands, kneading them bra and all.
"Ooh..."
The bra seemed designed for just this, yielding flexibly to his touch.
The soft, sinking give of her breasts combined with the bra's smooth texture.
Amazed by the exquisite harmony, Naibusu kept sighing in delight as his hands worked away.
Meanwhile, Akatsuki caressed the scar on Naibusu's chest with an entranced expression.
A massive scar that would repulse most people—yet she pressed her lips to it as if mesmerized.
And she kissed it with an audible smack.
"...Hoo... *smack*."
"Eek! Teacher Akatsuki...!"
A vivid red lipstick mark remained where her lips had pulled away.
The sharp sting made Naibusu shudder and groan like he'd been electrocuted.
Naiad, who had been watching the two with clenched fists and trembling body, finally couldn't hold back. She shot to her feet and shouted.
"Hold on! Teacher Akatsuki!"
It was like dumping cold water on their heated moment.
An outrageous intrusion from someone who was just an observer.
Akatsuki furrowed her brows slightly and said,
"...Teacher Winzer. Didn't you promise not to interfere?"
"I-I did! But... but!"
Naiad had indeed been granted permission to observe on the condition she wouldn't butt in midway.
Observers observe—that's it. They don't meddle in the lesson. As a teacher herself, Naiad knew that basic etiquette all too well.
But she couldn't just sit there watching.
She didn't know what this surging emotion in her chest was. All she knew was an obsessive urge that she had to stop them somehow. Naiad acted on pure instinct, without a second thought.
Naibusu, who had been utterly fixated on Akatsuki's breasts, looked flustered as he glanced back and forth between Akatsuki and Naiad.
Where was the Naibusu who'd worried about his big sister? He seemed to only now realize Naiad was even there. And even in this moment, his hands never stopped groping Akatsuki's breasts.
Akatsuki let out a light sigh and asked,
"So, what's the problem?"
Naiad was at a loss for words.
She'd interrupted out of sheer anxiety, but she had no real justification for disrupting them.
"L-Lipstick! It won't come off if it gets on the uniform!"
With nothing else to say, Naiad blurted out that lame excuse.
It was true—lipstick doesn't wash out easily from white clothes.
But it hadn't stained any clothes; it was on bare skin. And even if it had, that wasn't reason enough to stop them.
"Haa."
Akatsuki sighed loudly enough for all to hear and said,
"Teacher Naiad Winzer. Your brother isn't a child anymore. How long do you plan to keep him wrapped in your skirt?"
"Ugh..."
She had every right to snap.
But Akatsuki scolded her maturely, knowing Naiad wasn't acting out of malice.
"I understand a big sister's concern for her little brother. But babying him like that doesn't help him grow. Siblings must part ways eventually. You can't protect him forever just because you're his sister."
It was sincere advice from a senior teacher to a junior.
"Teacher Winzer. A fledgling bird must leave the nest when it's grown. Let your brother fly into the wider world."
Naiad had no retort.
Whether it fit the moment or not, there wasn't a single false word in what Akatsuki said.
And those words rippled deeply through Naibusu too.
Just as his sister clung to him, he was bound to her.
But they couldn't stay together forever. Their mutual dependence helped neither.
It was time for him to stand on his own, independent of his sister.
He knew it in his head, but his heart had resisted accepting it.
Yet hearing it from a third party, Naibusu had no choice but to face reality.
"Ah..."
Naiad slumped back into her seat.
Her legs had given out.
In truth, Naiad had known all along.
Her brother was no longer a child.
He no longer needed her care.
Everyone who knew Naibusu praised him unanimously.
Friends, neighbors, seniors, teachers.
He was trusted and loved by all. Naiad knew better than anyone that he wouldn't do anything to worry her.
But she'd stubbornly turned a blind eye.
She'd hypnotized herself into believing Naibusu still needed her touch, that without her watching over him every moment, he'd get into trouble.
After their parents passed, Naiad had lived solely for her brother. She'd desperately filled the void they'd left.
To her, he was her reason for living, her driving force. The grief of losing their parents had been bearable only through the sense of duty to care for him.
But now, that brother had grown into an adult.
He no longer needed her help.
No... truth be told, he might never have needed her at all.
It was she who needed him.
She needed that purpose in life he provided.
Without her brother, life would have no meaning.
Naiad was afraid.
Afraid of losing her life's purpose.
Her brother was her everything. But what if she was no longer needed by him? That fear gnawed at her.
"Sis..."
"Teacher Winzer. Just watch from there. Watch the moment your brother becomes a man."
But now, she had to accept it.
This was the ritual of sending her brother from her arms.
"Now, Student Naibusu. I told you—during sex, you shouldn't concern yourself with any woman but your partner. Bad manners."
"Ah."
Akatsuki gripped his chin, turning his gaze back to her.
And this time, she pressed her lips to his.
-*Mwah*.
Lipstick smeared.
Not on clothes or skin, but on lips.
Akatsuki's mark was stamped on the lips of the brother Naiad had cherished and raised.
Naiad stared at the scene with vacant eyes.
And in that moment, she realized why she hadn't been able to hold back earlier.
She hated it. Hated seeing another woman's mark on her brother.
Hated how another woman could claim him so easily—a brother she could never have just because she was his sister.
But... but...
Now, she had to accept it.
Accept Naibusu's growth. His independence.
His sister had to accept it.
-*Smack, slurp, hum, gasp, smack*.
A deep kiss straight out of a foreign film.
Her brother was more adult than his sister. He kissed in ways she couldn't even imagine, as naturally as if he'd done it a thousand times.
And it wasn't just that. Naibusu was leading his adult teacher, Akatsuki.
As if showing off to his sister. As if proving to her how much he'd grown.
Akatsuki was just as thrown by it all.
"Gasp, smack, mmph, ngh, slurp. Huh?!"
She'd only meant a light peck at first.
Just to show 'adult poise' and watch the innocent student's face flush.
But Naibusu's counterattack exceeded her wildest dreams.
His tongue slipped in so naturally, swirling through her mouth, sucking on hers—Akatsuki lost herself completely.
It was just like last time. She'd be toyed with in no time.
"Mmph?!"
Before she knew it, his hand had invaded her skirt.
She'd used her breasts as bait to protect that spot, but she'd surrendered it already.
Distracted by the kiss, she'd lost control. Akatsuki hurriedly unzipped him and pulled out his manhood to regain the upper hand.
*Thud!*
It sprang free with the force of a dramatic sound effect.
Fully erect, veins bulging like it was furious, it boasted a presence rivaling Akatsuki's breasts.
That ferocious sight was the most undeniable proof that Naibusu was a fully grown adult.
While his sister hadn't truly matured yet, still seeing her as the little girl from a decade ago.
Her brother had already grown up and was walking the path of adulthood.
"Mmmph, smack, slurp, gasp, mwah..."
Akatsuki hurriedly gripped it and started stroking. Overwhelmed by the kiss, even her hand moved unsteadily. Tongue, breasts, pussy—all assaulted at once, her mind was blank.
But Akatsuki persisted with her hand.
Her lower belly quivering from the direct attack on her weakness, she stroked diligently.
Determined to make Naibusu cum today. For all the talk, that was the original goal of this makeup lesson.
"Haa, haa, smack, slurp, gasp, smack. Gasp, nghhh—!♡"
Akatsuki squeezed her eyes shut and trembled. After all her lecturing, she'd climaxed first.
But it couldn't be helped.
Naibusu knew her weaknesses inside out, and he was resolved to show his growth to his sister.
Teasing Akatsuki was easier for him than eating cake. She couldn't be blamed for crumbling so quickly.
"Mmph, ngh, smack, whimper."
Even in the throes of ecstasy, Akatsuki desperately refocused and kept rubbing his cock. She prayed silently for him to cum, over and over.
And those prayers reached Naibusu. He was impressed by her mental fortitude—flailing in climax yet never stopping her caress.
He somewhat agreed with her wish to finish quickly. He needed proof he could satisfy without his sister, assurance that he didn't need her care.
For his sister to let go with peace of mind, they needed a decisive finale.
"Ngh... ugh!"
Naibusu didn't drag it out. The moment the urge built in Akatsuki's hand, he let go and unleashed.
-*Spurt! Splurt!*
An overflowing volume and force, impressive even after cumming multiple times that day.
It even splashed onto his sister's face.
"Ah."
Naiad, dazedly watching the scene, finally snapped back at the hot sensation on her face.
The semen splattered on her cheek trickled down like tears.
