Chapter Title: Eirin Who Came to the Annex on Her Own
-----------------------------------------------------------------
Late at night, Eirin stood in front of the annex's main gate.
Unlike our first meeting, she glared at me silently, dressed in a red sweater and a black miniskirt.
Worried someone might overhear, Eirin grumbled in a very quiet voice.
"Hey, why'd you take so long to open the door? Jeez..."
"Young Lady, welcome..."
Before I could finish, she strode into the annex, plopped down on the living room sofa, crossed her legs, and folded her arms.
Once inside, her confidence returned, and she spoke loudly as before.
"You! What the hell were you thinking, getting my sister to send me that weird note? Unbelievable!"
She clicked her tongue and turned her head away, like a chihuahua putting on a tough act.
'Ha... Her tone hasn't lost its edge, but her body's starting to tremble a bit? Crossing her legs to hide the shaking? Kinda cute, actually.'
I smiled at her and extended my hand.
"I've prepared some refreshments for you in the tutoring room. How about we move there?"
Eirin, still with her arms crossed and head turned away, shot me a sideways glance and replied irritably.
"What? Who do you think you are, telling me what to do? Right here! Right now! Spill it. Why'd you call me here with that ridiculous note?"
She snapped at me but trailed off as the note's contents came back to her.
'The fact that she even came here means she's already accepted it to some degree. Dumb girl.'
"You probably snuck out, right? The tutoring room is well-insulated from the outside, so it'd be perfect for a private talk."
Eirin hesitated for a moment, then stood up and lightly kicked my shin.
Hiss
"You should've led with that! Show me the way."
'Ha... Insolent brat... I must've been crazy for a second thinking she was cute just because I saw her tremble a little.'
On the tutoring room table were chamomile tea, strawberry cream cake, and macarons in various flavors.
'Even Adelin, after eating food infused with my mana firsthand, started getting corrupted bit by bit. For a rookie like Eirin who's only just awakened her mana, it'll work without fail.'
Eirin sat in a chair, crossed her legs, and griped.
"Hey, tutor. You think I came here for this crap dessert? What's your goal? Want me to get you kicked out of the house right now?"
Emma, who had followed us into the tutoring room, spoke up to Eirin.
"Young Lady, give it a try. It's made with the capital's most popular recipe—even the Lady of the House raved about it."
Intrigued by the mention of Adelin enjoying it, Eirin finally cut a small piece of cake with her fork and popped it into her mouth. Her eyes widened, and she silently devoured the entire slice.
'Must run in the family—she's a total dessert fiend, just like her sister. Of course, my mana makes it taste even better.'
After finishing the slice, Eirin flushed slightly, embarrassed, and praised Emma.
"Hmph... Yeah, it's... tasty? You're pretty good at cooking, Emma. G-Good job."
Beaming at the compliment, Emma offered more treats.
"You'll love the tea and macarons too."
Eirin nibbled a macaron, sipped the chamomile tea, and dove back into the desserts with abandon.
'What's her deal... Does she just have a huge appetite? If she becomes my slave, I'll have to manage her diet.'
As she reached for the last macaron on the tray, she snapped out of it and turned to me.
"Right, that's not the point... You! What was your name again? Jin! Why'd you send me that note? Ella didn't read it, did she?"
Thanks to my mana seeping into her body, she was starting to perceive me positively—she even said my name for the first time, her tone softening just a tad.
'If she reacts like this, it's too easy. I just needed to create an opening for the corruption to begin, so I trusted Emma's assessment and took the bait... Spot on.'
"For now... Ella doesn't know your true feelings, Young Lady. But if you try to get rid of me... I can't guarantee it stays that way."
Eirin slammed the table with her hand and shot up from her chair.
"W-What do you mean 'true feelings'? I-I could tell Mom right now and have you thrown out! Got it?"
'As if... At least for the next month, even for Ella's sake, Adelin won't kick me out.'
"Hmm... Lady Tolly probably won't act on whatever you say, Young Lady. At least not for the month she promised... And in my judgment, Ella will awaken her mana within that month."
Realizing my words rang true, Eirin sat back down, crossed her legs, tilted her chin up, and said,
"W-Well, good for her! Sis has been through hell over that! If she's happy, I'm happy too!"
She tried to sound haughty, but her trembling voice betrayed her.
"You don't want Ella to awaken her mana, do you, Young Lady? You can be a little honest now."
Her face reddened with suppressed anger, her body quivering as she replied.
"W-What...? You! That's not true at all... Y-You... Hmph!"
Suddenly, mid-sentence, Eirin clutched her chest as if short of breath, tears welling up.
'What...? She's just a kid after all? Breaking down in tears because she can't hold back her frustration?'
"Of course, your true feelings aren't just that you want Ella unable to use mana, right? You want her to 'especially' rely on you, don't you?"
"Hmph... Say that's true, keep going."
"If Ella awakens her mana and becomes independent, the relationship you want won't happen. Shall I be more direct? You want her body—like lovers."
'If my mana corruption hadn't started in her body, she'd be flipping out right now. How will she react? Too bold mentioning her body outright?'
I watched as Eirin sniffled, eyes downcast, saying nothing.
After a moment, she abruptly yelled at Emma.
"If you're a maid, shouldn't you refill the food without being told? Get more, now!"
'...Crazy girl, venting her frustration in the wrong direction because she's frustrated.'
Once Emma left the room, Eirin leaned toward me and whispered quietly.
"H-How did you know? Is it that obvious? You've barely even seen me. Did Sis figure it out already?"
Her voice thick with emotion, she whispered anxiously. I revised my assessment of her slightly.
'I thought she was just an arrogant, rude kid, but she's dumb and innocent too? She can handle mana, so her perception shift isn't complete like a commoner's would be...'
"No. Few sisters would suspect their sibling of desiring their body. Actually, the reason I called you here isn't to blackmail you—it's to help."
At the word "help," her eyes lit up, and she spoke with uncharacteristic warmth.
"H-Help? Me? How...? Can you make Sis love me? See me as a lover?"
'This goes beyond innocent—straight-up idiot.'
"Well... I can't promise, but if you take my lessons, you might get a chance."
Eirin tilted her head, confused.
"What does me taking your stupid lessons have to do with anything? And if I become your student! What's in it for you?"
"First off, I won't have to worry about you getting me kicked out. And as a tutor, teaching someone with your overflowing talent isn't an opportunity that comes often. Especially for a mere home tutor like me."
Her lips twitched at the praise.
"Y-Yeah, that's right! I'm kind of a genius. Teaching average people, then getting someone like me—you'd get greedy. Yeah, yeah. You've got an eye for talent. So, what exactly do you mean by helping me? Be specific."
'A few compliments and she's eating it up...'
"When you two enter the academy later, Ella might struggle because her awakening came from education, not naturally. Nothing major, just temporary discomfort... Without me there, if you learn from me..."
Interrupting me, Eirin exclaimed,
"I can help Sis at the academy and get alone time! And when she's struggling in a strange place, I'm the only one who can help, so she'll rely on me more... If that continues, then... Hehe."
Mid-sentence, she trailed off, staring at the ceiling with a grin, lost in fantasy.
'She doesn't care at all that Ella could have issues from what I teach her. Sees it as her chance and laughs? Poor Ella, having a sister like this.'
"Ah! Of course, I'm not asking for a decision right now. I'm always awake at this time on weekdays, so come back whenever suits you."
"W-Well, as a genius, I'll think about it specially! No more to say? See you later, Jin."
'Coming back at the same time means she's already... accepted. Dumb girl.'
As Eirin headed for the gate, Emma handed her a paper bag stuffed with diffusers, bath salts, and treat sets.
"You seemed to love them so much earlier, so I packed similar ones."
Eirin took the bag with one hand, turning her head away slightly.
"W-Whatever, not like I'm grateful or anything, but for your effort, I'll take them specially. I'm in a good mood today."
'Her face says she's thrilled. What a bratty act.'
[Main house, Eirin's bathroom, past midnight]
The walls were clad in dark gray tiles, the floor in light gray marble. In the center stood a large bathtub, its exterior black, interior blindingly white.
Eirin lay submerged in the tub, overflowing with purple bubbles, fondling her pussy and breasts.
"Hahhh... Heut♡ Hearing someone else find out about my feelings for Sis today... it makes me even more excited. Heut♡ Haa♡"
From the treats during our talk and the bath salts now, my mana had seeped into her body, amplifying her arousal far beyond normal—but Eirin didn't notice.
"Heung♡ Ella Sis~ Do your breasts feel like mine? Hahut♡ Ours are about the same size, huh? Haung♡"
"Feels like my wish might actually come true. Hah... Heut♡"
Alone in the bathroom, Eirin didn't stop at lewd thoughts—she voiced them aloud, getting even hornier.
Squelch squelch
"Heut♡ If I rub Sis's breasts... her precious parts like this, haaang♡ she'd moan too, right? Hahut"
"And if Sis gropes my sensitive spots...! Haaaang♡"
'Jin's words make sense. Leaving home for a strange academy—I'm the only one who can help her!'
'Use healing as an excuse to touch her bit by bit, get her used to my hands? Maybe even addict her? So eventually she craves me herself... Hehe♡'
Imagining Ella desiring her, Eirin arched her back, squirting from her pussy.
Squirt squirt squiiirt
"Haaaaah♡ Just imagining it makes me cum... Ah! I wanna touch you, Ella. I love you♡ Love you♡ Love you♡"
'Yeah! I'll accept Jin's offer and go for it. Thought he was just a pest, but he's a lucky charm. Hehe.'
Eirin spent the night in the purple water, squirting several more times before finally leaving the bath.
