Chapter Title: Eirin's Pussy Tastes Like This
-----------------------------------------------------------------
"...Please. Help me, Teacher..."
Eirin's desperate polite plea hits just the right note with me.
I start the massage from the tips of her fingers as she lies there, rolling up her sleeves bit by bit.
When her clothes snag at her elbow and won't go any higher, I look into Eirin's eyes.
"This is purely for treatment, okay? Mind taking off your sweater? I can't massage any further like this."
Eirin hesitates for a moment, then her overheated body twitches uncontrollably, and she finally slips off her red sweater.
Her snow-white skin contrasts sharply with the black bra, and her full, voluptuous breasts are impossible to hide.
"D-Don't stare too much..."
'Back to the rude tone already? Teaching this girl manners is such a chore.'
"Stare? What are you talking about? I'm just checking your condition."
I answer her and run my hands over her warm, creamy skin—first her underarms, then her collarbone.
Sure enough, mana is circulating nonstop inside Eirin's body, giving off a faint heat wherever I touch.
Hnnngh... Hnng... Hngh...
As the massage continues, her erogenous zones get more stimulated, and she starts twitching more frequently.
Eventually, Eirin begins rubbing her thighs together against her groin noticeably.
I glide my hand smoothly down the side of her body from her collarbone.
When I pass her breasts, I deliberately brush the outer swells to tease her.
Hnnngh! Hngh! Hnnh!
The breast stimulation proves too much—Eirin can't hold back anymore and bucks her hips several times.
When my hand reaches her navel and snags on her hip-area jeans, I speak to her again.
"Looks like the upper body alone isn't enough. Mind taking off your pants too?"
Even more aroused now, Eirin stands right up and strips them off without hesitation.
Her black panties are already soaked with her juices, and more trickle down her thighs, stirring me up.
'Whew... Just a little longer, and I can finally fuck this girl for real.'
I massage her pelvis and lower belly thoroughly with both hands,
then slide down to her thighs, subtly grazing the entrance of her pussy with my finger.
Hnnnngh! Hnngh! Hnnngh!
Even that brief touch sends Eirin over the edge—she bucks her hips wildly, squirting from her pussy harder than before.
Pshhh... Pshhh...
"Ah... N-No! It's not pee! Hnnngh!"
'Like sister, like sister—even down to the wording, just like Ella.'
I wait for Eirin to calm down a bit, then meticulously massage from her thighs to her soles.
Afterward, I stare straight into her eyes. The deep blue of Eirin's gaze is tinged with purple, satisfying me.
'Perfect. At this point, even if I do nothing, she'll beg me for it.'
After some time passes with me just watching her,
Eirin—still rubbing her thighs together—finally speaks up, her face flushed with embarrassment.
"Um... these remaining clothes are probably getting in the way of the treatment... right?"
It's informal, but I can feel her resolve cracking compared to the forced politeness from before the massage.
"Well... yeah. But you okay with that? I don't mind, but I figured you'd be self-conscious."
Unable to bear my hands staying away as her tremors worsen, Eirin stands and starts peeling off her underwear.
Breasts as large and perfectly shaped as Ella's, but with slightly darker pink nipples;
neatly trimmed pubic hair, and a neat slit for her pussy.
Eirin exposes it all without covering up and lies back on the lounge chair.
'Whoa... What blessed genes. How can a body be this flawless? Both sisters have perfect figures.'
"You keep that bush maintained regularly, huh? Basic etiquette for a noble young lady?"
"It's... just personal preference."
One hand kneads Eirin's full breasts, tugging her nipples; the other fondles her pussy lips.
It's foreplay indistinguishable from sex, but Eirin just breathes heavily and stays still.
"Haa... Haa... Feels good... Like something's slowly unraveling... Haa haa..."
I slip my index finger slightly into her pussy while caressing the lips, and Eirin suddenly bolts upright.
"Ah! Not there... Um... Unless it's absolutely necessary..."
"Every time my hands touch you, your body calms down, right? Looks like your erogenous zones were the issue."
Hearing that, Eirin scowls and snaps at me.
"Huh? Are you calling me a pervert right now? Saying that's why my body's like this?"
'Her attitude hasn't broken yet.'
"It's not that simple. Your feelings for Ella were probably different when you were kids, right?
What kind of sister loves her sibling so much she wants to restrain her and fuck her?"
Eirin doesn't call me out for using Ella's name casually or describing her feelings so bluntly.
Instead, she just looks flustered, like I've hit the nail on the head.
"Wh... What?"
"Think about it. At some point, Ella stopped being just your big sister and became someone you wanted to love.
More precisely, someone you wanted to fuck and dominate sexually.
And don't you feel something like that toward me now too?"
Eirin covers her face briefly, takes a deep breath, and speaks.
"Hoo... Th-Then...? How...? So all those feelings are because something's wrong with my body?"
"Seems like your naturally superior mana core got tangled up with your affection for Ella.
Twisted into warped sexual desire.
With no outlet, it built up inside you until it erupted this week."
'It's just nonsense mixing mana cores and lust, so it doesn't make logical sense.
Truth is, Eirin was a siscon by nature, and my mana made her hornier than usual.
Plus, the suggestion linked her siscon obsession to me too.
But right now, with the right keywords, she'll buy that she's the problem no matter what.'
"Th-Then! What do I do? Can you fix it?"
"Of course—solve the root of the lust. Drain the sexual buildup from your mana core, and you'll live normally again."
Eirin rolls onto her stomach on the chair, burying her face, thinks for a moment, then turns with a determined look.
"H-Help me!"
I scoop her up princess-style and head to my bedroom.
Emma, whom we pass on the way, wears a beaming smile. As I go by, I whisper in her ear.
"By tonight, what you've wanted will come true. Consider it a reward for your devoted service."
"Yes. Thank you."
Eirin doesn't even care what I'm saying to Emma.
She clings to my neck with her arms, pressing tight against me as she fights to suppress her raging arousal.
In the bedroom, I lay Eirin on the bed and say,
"Alright. Tell me exactly what you want me to do to you.
You know I'm just a commoner—if you change your tune later, I'm in deep shit."
Her face flushed red, Eirin enunciates clearly.
"To heal my body and mind... resolve the issue built up in my mana core!"
"Is that really all you got from what I said? You're not that dense.
Be specific if you want me to trust you and treat you."
Eirin squeezes her eyes shut, her body trembling, and tries again.
"Nnnngh! Stimulate the inside of my precious place with your thing... and resolve my lust!"
"Can't say no to a good student's request, right?"
I strip off my clothes, lift Eirin's legs into a V, and rub my cock against her pussy entrance.
Schlick... Schlick...
Hnnnngh!! "Th-That thing's going inside me? My precious place will tear apart... No, hnnngh!"
Just rubbing the entrance makes Eirin squirt hard, climaxing.
Juices splash onto me, but even mid-orgasm, her eyes stay glued to my cock in terrified fascination.
"First time seeing a dick? They're all about this size. It'll hurt at first, but I'll be gentle—just endure a little."
'It's the only dick you'll ever see in your life anyway, so not a lie.'
I slowly push my cock into Eirin's already slick pussy.
"Ah... It hurts, it huuuurts! S-Stop putting it in... It's ripping me! Hnnnngh!"
Eirin throws her head back in pleasure-pain, crying out.
"Quit whining like a baby! Where's your patience?"
I ease my cock deeper, reposition her legs into an M on the bed, then slap her pussy lips hard.
Slap!
Haaaang♡
I sense a surge of mana in Eirin's body the instant she screams.
"If you use magic to push me out, no more treatment—ever."
"S-Sorry... It hurt so much in the moment... I'll endure, sorry... Hnnngh♡"
Pushing deeper ruptures her hymen, and faint red blood trickles from her pussy.
"Wh-Where's it going? It hurts... Hurts so much..."
I roughly slap her pussy lips again.
Slap! Slap!
Hnnnngh♡ Hngh♡
Each slap makes Eirin climax even harder.
'She gets off more on the slaps? Masochist, huh?'
"Shut up and endure it, you worthless pussy bitch. Quit your pathetic whimpering. Who's helping who here?"
Despite the insults, Eirin doesn't argue back—she just covers her mouth with both hands.
Groooan...
Finally, I hilt my cock deep in her pussy and grind long and hard, marking her.
"Hnnnngh! Wh-What's this? Feels so good, hnnnh♡ Keep pressing! Hnnngh♡"
Eirin's eyes roll back as she bucks her hips.
'Worthless bitch cums just from marking. And why does her first time feel this good? Born sex slave.
Once I creampie her pussy and her mana falls under my control like Ella's...?
It'll prove I can enslave any noblewoman with a creampie.
Haa... Can't wait to test it—gotta verify now!'
I start pistoning fiercely in her orgasming pussy.
Squelch squelch splurt splurt splurt
Hngh♡ Hnnngh♡ Hngh♡
Every thrust makes Eirin buck wildly.
Her face is already lost in ecstasy—mouth agape, tongue out, drool streaming.
'Cum-dump pussy bitch. Pounding you hard and you're trying to pass out?'
I lean my upper body down and slap her cheek.
Slap! Slap!
"Hey, worthless pussy! Snap out of it! You need to feel your body's condition properly!"
"Eh... Ehhhngh♡ Wh-What'd you call me...? Hngh hngh hnnngh♡"
As awareness returns and she glares, trying to retort, I slam harder.
She cuts off mid-sentence, mouth gaping in moans again.
"Nngh... Feels too good... Can't think straight♡ Hnnngh hngh hngh♡"
Slap! Slap!
I slap her cheek again to wake her as she drifts back into pleasure.
"Worthless pussy bitch! Stay focused! If you pass out, this is all for nothing!"
"B-But I've never felt pleasure like... Hngh♡ Hnnggggh♡ It's so good my head's gonna explode! Hngh♡"
'Well, her mana's constantly stimulating her whole body, so yeah, more intense than normal sex...
But among the girls I've fucked since coming to Deid region, she's the weakest pussy. Nonstop orgasms.
If I hadn't slapped her awake, she'd have blacked out ages ago.'
"Alright, time for the root treatment finale!"
I creampie her pussy without warning her.
Too weak to resist, Eirin just wails in slutty ecstasy as she cums.
Shudder quiver buuuurp
"Hnnnngh♥︎ N-Nooo♥︎ You didn't say anything about thiiiis♥︎ Hnnggggh♥︎"
As my cum fills her pussy, purple light emanates from her womb amid her screams, and she passes out.
Slap! Slap!
Even hard slaps to her cheeks, breasts, and ass post-creampie don't rouse her.
I slap her tits and ass while pumping two more creampies into her, then leave the room.
'That womb glow like Ella's means Eirin's submission is total.
Once she wakes, confirming I can block her mana use will make this a perfect day.
Well... her training starts now, technically.'
