Until Returning Home with My Sister (2)
Having regained my strength, I fought alongside the heroes against the monsters once more.
I can protect Sis again... I'm so relieved. Back-to-back with her, we exterminated the beasts.
I'll never let Sis get hurt again... I'll protect her.
I blocked every threat coming her way with the power of the spirits. I attacked those disgustingly repulsive blobs of flesh with pure hatred.
"Die!"
Channeling my rage at my own inability to resist Leon Sodus, I commanded the fire spirit. The leech-fly hybrid monster swimming through the air twisted and shriveled as it burned in azure flames.
While venting my stress by tearing the monsters apart, I noticed the battle felt far easier than usual.
It's not even hard...?
Unlike before when Sis and I fought back-to-back alone, the fight flowed unnaturally smoothly now. It was a one-sided slaughter. The monsters couldn't mount any real resistance and kept getting pushed back.
There was only one difference. Sis and I were now fighting mixed in with the other heroes.
My attack-focused powers alone couldn't support Sis properly, but with help from the two grand mages, every issue vanished.
The Blue Tower Lord and her equal in magic. Bella Sodus and her array of support spells could turn even a fumbling warrior into a hero of reversal.
And since the beneficiaries were the two strongest elves around, the effects shone even brighter.
Wind spirit-enhanced projectiles kept coming, perfect for launching. Spirals carved into the spinning bodies let them self-correct mid-flight toward their sharp tips without manual adjustment. Aerodynamically designed, efficient, and sturdy.

They fly twice... no, three times faster...
The projectiles sank deep into the beast's hide, cracking its tough exterior with fine fissures.
"Graaaah!"
Even as it righted itself to press the attack despite the splitting shell, a barrage of powerful magic bullets from Bella rained down. The beast screamed again in agony as it was roasted alive, collapsing in the pose it had tried to rise into.
"Grrraaah..."
Enduring the attacks that shattered its sturdy carapace, the monster sucked in the surrounding air amid its torment, preparing a counterstrike. The pressure dropped sharply from the massive volume of gas it inhaled, then it fired its broken scales like cannon shells under immense force.
A thousand or more razor-sharp spines poured out, like a rain of arrows.
Sis's sword alone couldn't block the storm of thin, needle-like barbs, but the two mages' force field stopped them cold. The one-way field accelerated Sis's blade while repelling the light, slender spines entirely.
Sis gave a slight nod of thanks, then sliced into the now-defenseless beast's flesh.
With the lead monster down, the rest scattered in instinctual panic.
"Incredible... So this is the power of grand mages on the battlefield...?"
What had been a dangerous tightrope walk with Sis and me alone was now a unilateral massacre. If the old fights felt like they could end in injury at any moment, this was as simple as twisting a child's wrist.
Watching their versatility in action, I thought maybe these two could solve my problem.
If it's them, they might fix my issue...
They might even know how to block unwanted overwhelming pleasure.
As the battle ended and I pondered how to approach them, they came to me first.
"Estelle! I heard the news. You're becoming Leon's slave?"
Her sapphire-blue eyes sparkling, she greeted me with innocent cheer.
"Kuhk!"
Their naive question made me spit out my drink.
"Cough, uh, yes?"
It felt like half of it had gone down the wrong pipe.
Asking if I've become a slave like it's casual chit-chat about a new outfit...?
Steadying my breath, I replied to her.
"What... do you mean?"
"Oh? Leon said you and Lora had become his new slaves... Isn't that right?"
Leon Sodus... What the hell are you telling people...!
I still had to play the part of his slave, so I gritted my teeth and nodded. I didn't expect rescue, but seeing these human heroes treat the news like morning weather talk plunged me deeper into despair.
Filthy humans... Their own kind enslaving elves, and they don't care?
Like son, like mother. I couldn't hide my contempt.
Maybe chastity and morals only mattered in the forest. Even these supposedly noble, elite human heroes were this sexually depraved.
The Blue Tower Lord's reaction was no different. Instead of shock or outrage at the slavery news, she just nodded like "I see" and snuggled right into Bella's arms.
All humans... like this?
Their follow-up turned my stomach.
"That's great! Congratulations, Estelle!"
"I'm jealous... Takes me back, Senior."
"Right? Hehe."
Congratulations...? Are they all insane...?
They giggled, exchanging knowing looks at my humiliated expression, like it was hilarious.
Dirty, vile humans...
Forcing a fake smile, I asked for their help. Perfect, actually. With their twisted morals, they'd fall for my act even harder.
"...Um, my body is so sensitive that serving Master is a bit tough. Could you help?"
Playing the loyal bitch devoted to her master—Leon Sodus.
"Oh, really? How admirable! Thinking like that."
"A model slave's mindset. Looks good on you, Estelle!"
Why... does this conversation even make sense...? Isn't making slaves despised even in human society...?
Confirming I was Leon's slave, they praised me warmly, like it was fantastic news. I could feel their fondness for me skyrocket.
This is weird...
I couldn't hold back and asked them outright.
"...Isn't it strange? That I've become his slave? Doesn't it shock you? Have you always supported slavery?"
Only after snapping in anger did I regret it. But they just smiled leisurely.
"Well... Slavery is definitely an abhorrent relic of the old world that should vanish... but becoming Leon's slave is different, right?"
Bella Sodus waved it off like I'd said something silly.
Irina Belnova clung to her, laughing. "Exactly! You should realize how lucky you are, Estelle."
"...Pardon?"
Her bold claim—that being enslaved was lucky for the victim—left me stunned beyond shock, like my head had been smashed with a hammer.
What... the hell? Am I the crazy one...?
My known common sense was being denied. We spoke the same language, but their thought process was alien.
They looked at my shocked face oddly and said,
"You don't think becoming Leon's slave is the same as ordinary slavery, do you?"
Bella grinned playfully, like her words were a funny joke.
Even worse was Irina's giggling response. "Come on, Senior. Don't tease her with elf stereotypes. She's a bit naive, but she's a hero—she gets it, right?"
The ground of my common sense crumbled beneath me.
What... are they saying...?
I knew they were wrong, but doubt crept in.
Why affirm my enslavement...? And what's this about Leon's slaves being different...?
My familiar logic never worked with this group. Sis conversed and connected with them fine, while I couldn't understand. My convictions started fading.
Is this... right...? Or am I... wrong...?
Irina gave me a wistful look. "Aw, you're so confused... Poor thing... If only you'd realize soon... ♥"
"Hmm, how about this...?"
"...force... to... all at once... Ah, genius! As expected, Senior!"
They whispered so softly even elven ears barely caught fragments, chatting without me.
Finishing their secret talk, Irina pressed her mana-wreathed hand lightly to my lower belly. Rune letters slithered like living snakes from her fingertips, through my clothes, embedding into my skin.
"Hngh...?! What... is this...?"
"The way for Hero Estelle to endure pleasure, just like you wanted ♥ The effect... hehe... you'll know soon ♥"
"Wait, explain... at least!"
"Nope~ Let's go, Senior!"
With mischievous grins and tongues stuck out, the two mages teleported away.
"Wait, where are you going!"

I hiked up my skirt to check my belly—no trace. ...Wait, on closer look, a nearly invisible mana pattern faintly swirled across my lower abdomen, unnoticeable without scrutiny.
They did something... but what...?
I tried to chase them, but Sis found me first.
"What are you doing, Estelle? Master is calling us!"
"Ugh... Got it, Sis..."
At her urging, I headed to Leon Sodus's room without any explanation.
Wanting to use us right after the extermination... We're not your toys...!
Ecstatic at his summons, Sis greeted him. "We're here, Master."
I steeled myself, vowing not to get swept away by waves of pleasure.
The man before you is the enemy... Not some master who makes you feel good...
No more dopey smiles the moment I saw him like yesterday. No legs giving out, no melting hostility. This time would be different.
I slowly opened my tightly shut eyes.
...Huh?
My mind was clear. The tattoo Irina had etched glowed softly, shielding me from pleasure.
Even before his cock, I kept my sanity and could hate him freely.
This is... my chance!
Using this golden opportunity, I'd play the perfect slave to extract info. If lucky, maybe even find a way to break Sis's brainwashing.
If I learn how to free Sis... you're done...!
This time, I acted the part flawlessly, feigning pleasure and fawning over him.
I won't lose this time!
...At that moment, I didn't know the once-transparent tattoo was gradually tinting pink with every touch.
