Until Returning with My Sister (1)
"Ahh...! Ahhh! Aaaah!"
"Still at it? Come on, breakfast time! Estelle!"
Ignoring my big sis Lora's voice from outside the door, I buried my face in the pillow and screamed.
What the hell was I thinking yesterday...!
The memory of sucking that hated man's cock and climaxing came back crystal clear, turning my face beet red.
My first orgasm in life... while swallowing that filthy liquid...'
The pleasure I'd endured through Sis's teasing had exploded when I swallowed his cum, filling my head like a torrent. My mind, unable to withstand the rush, had shown a perfect 'obedient elf slave' act without even faking it.
I'd kissed that filthy, stinking dick with affection multiple times, even thanking him for letting me serve it. And before blacking out, hadn't I thought something horrific like, 'A slave's life isn't so bad'?
I couldn't stand it—couldn't believe yesterday's me, couldn't forgive my mind for falling to his brainwashing.
"Get it together, Estelle...! You have to save Lora sis... Ow!"
As I kicked off the blankets to vent my regret over yesterday's pathetic defeat, Sis flicked my forehead.
"Ow, Sis... That hurts..."
"Enough of that. Change into something pretty. Master said he'll restore your power today."
At Sis's shocking words, I bolted upright in bed.
"For real?!"
"What're you so surprised about? You're Master's slave now too, so of course he'll give back your power. It's no big deal."
Sis, more excited than me—the actual person involved—fussed over me like I was a doll, holding up outfits.
"This one pretty? No, this shows off Estelle's charm better... Estelle? Don't zone out!"
I was dazed by the unexpected good news.
This fast...? I hadn't thought I'd earned his trust yet...
He must think he can control me...
I'd even steeled myself to suck his cock a few more times to get my spirit power back.
But he was even more arrogant than I'd imagined. The pleasure he'd given was intense, but not enough to rewrite my entire mind.
I'll make you pay for that arrogance, Leon Sodus!
***
It's been forever since I wore proper clothes...
Always left nearly naked, getting dressed right felt strangely fresh.
"Looks good? Estelle's pretty no matter what she wears."
Sis praised me, but warned as we reached Leon's door.
"Estelle, show proper respect to Master. I want you to really feel like his slave!"

Hmph, telling me to embrace being a slave... As if...
"Don't be shy—greet Master properly this time?"
Sis glared sharply.
"O-okay..."
Grumbling sulkily, I didn't want to, really didn't... but just this once, for my power back. Pretending to be a slave for a bit... unavoidable, right?
I took a deep breath and knocked on Leon Sodus's door.
At the "come in" from inside, I slowly opened it.
"Um, coming in...? Master...?"
The door opened, revealing him.
"...Ah."
Seeing his body instantly revived yesterday's memories I'd tried to bury. The pleasure from serving him tried to sprout in my rebellious heart.
Clenching my hatred desperately, I steadied myself and spoke.
"Um, M-Master. I've come... to receive my power."
It's my power originally—why say 'receive'? Annoying.
"Oh, sure? Now that you're my slave too, you'll fight with me."
He answered casually, like it was a simple request.
Mana rippled at his gesture.
...Finally!
Just a bit more... and I'd reclaim my power from him.
"Just to check—once you get it back, you're not planning to attack me, right?"
"N-no way, Master...! Of course not!"
Sis hurriedly defended me, covering my awkward reply.
"No, Master! Estelle's never had disloyal thoughts like that! Right, Estelle?"
"Y-yeah... right...?"
For this moment, I was grateful for Sis.
Sis, I'll save you... right now...!
"Use the power I return for me."
"Th-thank you... Thank you...!"
With his words, mana surged, clearing my mind. I recalled the proper way to commune with spirits, long forgotten.
...You're done for now...?
I tried summoning a wind spirit to wrap his neck three times—but intense revulsion hit. Using power felt like my guts twisting in disgust.
Something's... off...
Every thought of hostility toward him brought nauseating loathing.
Why... why...?
I'd planned to kill him the instant I got power back, but my instincts fiercely rejected it. Soon, I 'recalled' why.
Right, not yet... the time isn't right...
Killing him here wouldn't guarantee Sis returned to normal. Rashly eliminating him without a plan could worsen things.
So this feeling... was rational.
Sis poked my back, urging the 'proper slave response.'
"Estelle? Say thanks?"
"Ah, uh... Thank you, Mas... ter."
Acting, just acting♥
The fulfillment filling my chest at 'Master'... must be over-immersion side effect.
With power back, chances aplenty. So faking deeper loyalty now... fine♥ Make him drop his guard♥
"As thanks, I'll... serve with my mouth...♥"
Teasing him cutely with Sis, I serviced his cock orally again.
"Good slave."
"Then... bon appétit...♥"
Saliva pooled from anticipation before even swallowing.
Remember, never forget hatred for this man... absolutely...
To fight pleasure, I recalled horrors: dead rat corpses, brainwashed Sis, cold chains.
"Hngh...♥"
Those vanished like magic once his dick filled my mouth. What disgusted me yesterday felt like prep for happiness.
His twitching cock cutely responded to my tongue; Sis's approving touch felt good.
No... can't melt this fast...♥
Continuing service made clinging to hate harder. Maintaining it amid this bliss felt like wishing cotton candy stayed intact in water.
I have to hate him, despise him. Hmm, but why again...?
Precum from his tip quenched my thirst like nectar.
I tried recalling reasons to hate, holding hostility.
Sis forced into pleasure, me too, by force...
Was that it? Felt like more...
Mind fogged with each suck.
Feels good... is that bad...?
Sure, he'd enslaved me by force, using Sis to confine me.
But he gives such pleasure... isn't he kind...?
He'd taken my power, confined me immobile at first... but returned it all now. Never really tormented me...?
If evil acts for good ends, not that bad...
"Hey, Estelle. Focus on Master's cock."
"Yessh...♥"
Sis's advice perfect. One more lick chased complex thoughts; simple pleasure replaced them.
Like a hungry baby on a bottle, Sis affirmed my lewd clinging to Master's dick.
"Our Estelle, such a slutty slave...♥ Sis is so happy...♥"
Urk...!
Sis's soft praise yanked me from pleasure's depths.
Sis wouldn't say that... She hated slaves...
His pleasure was dangerous. It shattered my vows in seconds.
Get it together, please, focus...
"Swallow it all."
He commanded lowly.
What? If he cums now... no...!
Against my thoughts, I reflexively deepthroated at his order.
Barely sane again, worst timing—his release hit.
"Hrrk...♥"
More familiar than yesterday, but his cum's pleasure still overwhelmed.
Hate it, hate... hate♥ Hate...♥
The rush brought my second lifetime orgasm, defenseless.
Master's scent, Master's taste, Master's happiness...♥ Why hate...?
Should hate, but love it too much...♥ Clear reasons existed before sucking... but melted like snow after swallowing his love proof.
"Haa...♥ Master♥ *smack* Masteeer...♥"
He helps Sis and me do this, gives solid love proof, makes happy... why bad? Affection for Master swells.
Tomorrow's me might condemn today's fiercely, but... that's not today's me, right?
Thus, I served kind Master who'd restored my power, with devotion and love.
Master rewarded, filling my belly with thick cum♥
"Haaa...♥ Master...♥ Thangk yoo...?"
Loath to leave his spent cock, I greedily licked remnants.
"Thangk yoo...♥ Master...♥ Hehe...♥"
Drunk on pleasure, staggering, Sis supported me back to our room.
***
Next morning, free of pleasure, fierce regret hit again.
Ah... Fell to pleasure again...
Couldn't resist, didn't use restored power, just submitted.
"This can't go on... Need a plan...!"
If I kept yielding to Leon—no, Leon Sodus's pleasure, I'd truly accept him deep down.
Then, no saving Sis—we'd end as happy slave sisters.
That future... no...!
I had to find a way. To resist his pleasure.
I resolved to seek help from another hero.
