Chapter Title: Tolly Family's Second Daughter Eirin
-----------------------------------------------------------------
Bang bang bang.
A voice laced with mana rang out from beyond the annex gate, shaking the building.
"Open up! I know Ella's in there!"
Ella, who had followed me out, pressed a hand to her forehead, while Emma let out a small sigh.
"Ahh..."
"Emma. Do you know whose voice that is? It's new to me."
"Yes, Sir Jin. That's Eirin, the Tolly Family's second young lady."
'Come to think of it, I haven't seen the second daughter before. Since coming here, I've only been to the main house that first time, so maybe we've never crossed paths.'
"After her Mana Awakening at this year's coming-of-age ceremony, Lady Eirin attended a spring camp for noble children. Today was her scheduled return, so she must have come straight here looking for Lady Ella after unpacking."
Bang bang bang. Bang bang.
The knocking on the annex door grew more intense.
"Can't you hear me? Open the damn door! Or I'll break it down!"
Eirin's voice boomed from outside the gate.
"For now, Emma, help Ella get dressed and stay with her in the tutoring room. I'll handle Lady Eirin."
"Yes, Sir Jin."
I waited until Emma had gathered Ella's clothes and taken her to the tutoring room, then opened the annex gate.
Standing before me was Eirin, her dark blue hair tied in a side ponytail. She wore a deeply plunging gray boatneck knit sweater and a short black miniskirt, hands on her hips as she leaned forward to glare at me.
"Hey! Where's my sister right now?!"
Eirin's blue eyes bored into me, but my gaze drifted to her chest—its size impossible to hide even under the knit.
'She's shorter than Ella, but they've got sisterly figures, huh.'
"Hey! Hey! Are you listening? Where's my sister? Class time ended ages ago!"
'It's not like we have set hours, so what's she on about... Though that chest and those thighs are a work of art. Tsk.'
I savored the view, licking my lips, then met Eirin's eyes and offered a greeting as she yelled.
"Hello, Lady Eirin. I'm Jin, in charge of Lady Ella's lessons. She's resting in the tutoring room with Emma now that class is over."
"I don't give a damn who you are. Take me to my sister. Why'd you take so long to open the door, you cocky bastard?"
Eirin casually kicked my shin with her black flats.
'Ow... This girl's insane? Barging in and starting shit out of nowhere.'
"My apologies, milady. I'll escort you right away."
As I led her to the tutoring room, she followed with her chin tilted up, arms crossed, muttering under her breath.
"Tch... The annex is full of memories with my sister, and you went and rearranged the furniture like you own the place? Ugh, annoying."
'She's saying that on purpose for me to hear, isn't she? What the hell is with this girl?'
I opened the tutoring room door. Emma and Ella sat primly at the table, sipping tea.
Eirin shoved past me as I entered, ignored Emma, and threw her arms around Ella.
"Sis~~~~! I'm back! Didn't you miss me? I missed you sooooo much—
The camp was full of boring losers, you have no idea how annoying it was. I mean, I'm just too popular, you know?
Of course, a genius like me put those pests in their place with magic."
'...Her own sister suffered without even Mana Awakening, and she's bragging about magic? Is she doing it to rub it in?'
"Sis~ You don't need to bother with silly magic! I'll handle everything for you! So skip this pointless studying and hang out with me~ I'd be happy glued to you all day looooong~."
As I listened to Eirin's words—mocking or clingy, I couldn't tell—I glanced at Emma. She stood impassively, as if used to it.
Ella gently pushed back the chattering Eirin hugging her and spoke.
"Eirin. We're not alone here. And why make such a racket coming into the annex... Apologize to Emma and the teacher first."
Eirin crossed her arms again, pouting.
"Tch. Sis, you're always~~~ thinking about others too much. I only have eyes for you... And why should I apologize to Dad's lowly commoner servants? It's their job!"
Ella frowned slightly and called her name.
"Eirin?"
Eirin recoiled a bit and turned toward me and Emma.
Still with arms crossed, she put on a mocking face and half-apologized.
"F...Fine! Emma, hey. Long time no see. Sorry if I was a bit loud! And you, tutor guy, sorry too."
Ella sighed, stood, and bowed to me apologetically.
"I'm sorry, teacher. My sister's still immature... Let me apologize on her behalf."
Seeing Ella bow to me, Eirin glared once then tried to pull her up by the waist.
"Ugh! Why's sis bowing to a commoner like that?!"
'Over twenty and still immature? Nah, just rude as hell. Did she get it from her psycho dad?'
Answering Ella casually might cause trouble later, so I replied politely.
"No need, Lady Ella. Lady Eirin did nothing wrong. I should have opened the door sooner."
Emma stood and bowed too.
"My apologies, Lady Eirin."
Seeing us both apologize, Eirin lifted her chin smugly.
"Well, at least you know your place."
'One day, I'll teach you some manners, Eirin.'
Suppressing my rising irritation, I instructed Emma.
"Emma, class is over. Please escort the young ladies back to the main house."
"Yes, Master."
As Eirin headed for the door, she deliberately bumped my shoulder.
"Ugh, can't you move?"
Ella paused by me, grabbing my arm and whispering.
"Um... Teacher? Are you okay?"
"You did great in class today, Lady Ella. See you next time.
Please don't scold Eirin on my account."
"Y-Yes..."
As Eirin exited the gate, she turned to Emma following behind.
"Oh! No need to walk me out. I want alone time with sis! Go do your job."
"Yes... milady."
The moment Ella stepped out, Eirin slammed the gate shut in Emma's face.
"Wow... That girl's a whole new level of crazy... Emma? Wanna take a break and tell me about Eirin?"
"Yes... Master."
I leaned back on the living room sofa and beckoned Emma over.
"Let's chat comfortably today."
Emma climbed onto the sofa.
"So... that blue-haired psycho—no, Eirin. What's her deal?"
"Well... Eirin doesn't treat those beneath her as fellow humans.
She sees them like cleaning tools or kitchenware."
"Yeah? From what I've seen of Lady Adelin's character, she wouldn't let that slide."
"Lady Adelin tried disciplining her many times—scoldings, lectures—but Eirin would run to Ruan crying hysterically that she did nothing wrong and Mommy was mean. It was routine.
Ruan would always say... well, he was the same way before adulthood, so Eirin would grow out of it naturally."
"Hah... Ruan's hopeless at raising kids too."
"Eirin's got a natural mean streak, but today she was worse because Lady Ella was involved."
Curiosity piqued, I pressed.
"Ella?"
"Yes. Eirin has an unhealthy obsession with her.
Before Ella's adulthood, it was just a clingy little sister vibe... But after Ella failed Mana Awakening and secluded herself due to the stares, it got worse."
"Hm... How so?"
"On the surface, she acts like only she can protect Ella.
But watching closely, it felt like nonstop gaslighting."
"Gaslighting? She kept bringing up mana earlier, subtly hitting Ella's pride."
"Yes... When Ella failed her Awakening, I think Eirin decided to keep her dependent forever, unable to live without her.
She probably wouldn't welcome Ella Awakening her mana."
'...A siscon with insane possessiveness.'
"Emma, sounds like you've got some pent-up resentment toward Eirin? Your tone's a bit heated."
"Yes... Master. Every commoner who's dealt with her feels the same."
I stroked the head of the clenching-fisted Emma as she spoke.
"Guess I owe my loyal slave a kitten as a gift."
Emma looked up at me with expectant eyes.
"A kitten...? Don't tell me... Like with Ella, Eirin too?"
"Aristocratic ladies who forget their place need etiquette lessons.
I'll think of a way. When the time comes, brainstorm how to handle her.
Anyway, tomorrow's our first weekend since arriving in Deid. I wanna check out the village."
Emma's eyes sparkled, already envisioning a tamed Eirin, her voice bright.
"Yes, Master! I grew up here, so I know it well. Leave the guiding to me!"
[Late Night, Eirin's Room]
The room, wallpapered in pristine whites, was furnished with dark-toned pieces.
A low-frame queen bed sat beside a matching three-drawer dresser on one side, while a black-stained solid wood desk and ergonomic chair occupied the other. The space felt cool and modern overall.
Eirin sat at the desk, leaning forward, gnawing her thumbnail.
Crunch crunch.
'What's her deal? I'll take care of Sis forever! She doesn't need to handle mana.
But what if she really Awakens? Goes independent and leaves me?
Then I can't protect her lifelong... No, that can't happen...
Ahh... Just thinking of Sis gets me so worked up...'
Before long, the center of Eirin's light gray panties darkened, the wet spot spreading as her arousal soaked through to trickle down her thighs.
'Ahh... Can't hold back anymore... I need to touch Sis's body, quick, ahh~.'
Eirin pulled her hand from her mouth, propped her legs wide on the desk, and began rubbing over her stained panties.
"Ahh~ Sis! You're mine. I'll make you love only me in this world. Love you, love you, haa... Ella Sis..."
Soon, she slipped her hand inside her panties, plunging fingers into her folds over and over.
'Ahh~ Oh yeah, that tutor had black hair, right? If I tell Dad, maybe he'll fire him?
What if that jerk fixes Sis and she leaves for the academy? Aa... Horrifying just thinking about it.'
Eirin moaned Ella's name loud enough to echo through her room as she kept masturbating.
"Ella... Ella Sis! You're mine, you can't go anywhere... Haa~."
