As I checked the mission, my words failed me once again.
Defilement... it was no different from outright telling me to rape her.
At least the completion condition was to activate her Lust toward me, but thinking about Mom and Older Sister—whose levels were still at zero—made it clear that even raping her wouldn't necessarily achieve that.
"Hey... did you hear what I said...?"
"Ah, y-yeah. I heard you."
The 'younger sister' glaring at me from the side, oblivious to her own impending fate...
"If you pull that shit one more time... I'll really kill you..."
"...You're gonna kill me?"
Whether I defiled the 'younger sister' and got beaten to death for it, or failed and the world ended—it all amounted to the same doom for me.
But leaving such a ripe, fuckable 'younger sister' alone didn't sit right with my temperament either.
"Yeah. So no more of that bullshit—kyaa, kyaaaaaang—! Hmmpf, mmph!"
"Shh, are you crazy?"
"Mmph! Mmmph!"
The 'younger sister' started screaming bloody murder just because I groped her tits a bit.
Her reaction far exceeded my expectations—it was so intense that I clamped her mouth shut first.
"Mmph! Mmmph!"
"Calm down a little. Huh? Why scream like that just because I touched your tits? What, are they gonna wear out or something?"
"Mmph! Mmmph!"
"Shh, be quiet... I said calm down?"
"Mm! Mmmph!!"
But the thrashing 'younger sister' showed no signs of settling down.
She was wriggling wildly, trying to break free from me.
If I'd known it'd turn out like this, I shouldn't have groped her tits right away—I should've talked her down first. Regret came flooding in belatedly.
"Hey, Park Seo-hyun!"
"Mmph! Mmmph!"
And she wasn't even listening to me.
"Ah, this is driving me nuts..."
If I let go of her now, who knows what crazy thing she'd do.
So, though it felt wrong, I clenched my fist and pictured the Sleep Inducer in my mind.
Sure enough, a pill appeared in my hand as if it had always been there.
I removed the hand from her mouth and quickly swapped it with the pill.
"Puhaa! You fucking bastard, fu—hmmpf! Mmph!"
This time, curses exploded from the 'younger sister''s mouth.
My other hand clamped over her mouth again, and I dumped the Sleep Inducer inside.
"Hng! Hmmpf!"
Now I just had to wait for the Sleep Inducer to fully dissolve in her saliva.
It felt like a real crime scene where I couldn't advance or retreat, pricking my conscience a bit.
*
Carrying a girl into a motel room in the bright red daylight was a novel experience.
More than anything, the unkind stares flying from all around were the most awkward.
I even felt the urge to slap a "My Younger Sister" sticker on her somewhere, but luckily, I found a suitable motel before any other mishaps occurred.
At the counter, they handed over the key without batting an eye, as if this scene was routine.
"Haaa..."
Yesterday and today—I'd been carrying people around a lot, I thought, as I gently laid her body on the bed.
The remaining drug effect was about ten minutes.
Pondering how to induce sexual shame in the 'younger sister', my first thought was to tie her up.
It was obvious she'd freak out and scream when she woke up, and no situation seemed more perfect for the mission than being bound.
Of course, with her in deep sleep now, there wasn't much I could do anyway.
With that, I started looking for something to tie her with.
The blanket caught my eye first, but it was too thick to serve the purpose.
Next, I considered using cords from the hairdryer or chargers, but they were all secured tight with cable ties, impossible to unravel.
"...This is insane."
Should I run to the convenience store for some tape right now, or just haphazardly wrap her in the blanket...?
As my frustration built with no good options, my eyes landed on the tacky curtains and the cord wrapped around them.
I knew instantly that was it.
Not super long, but plenty enough to bind hands and feet.
I first gathered her legs neatly and tied her ankles.
No—before tying, in my haste, I started stripping off all her clothes.
I undid the tight pants clinging to her body and yanked them downward.
Her ass was so damn huge that the pants snagged, refusing to slide off easily.
After struggling alone to peel them off completely, I went to rip off the pure white panties in one go, but then moved upward instead.
I was already swamped, yet these damn buttons—endless, no matter how many I undid.
Telling myself it was just nerves, I kneaded those massively huge tits a few times to steady myself.
"Haaa... fuck... this is fucking exhausting."
Sweat that hadn't flowed while carrying her now beaded on my forehead.
I wiped it roughly with a towel, then gathered her legs again and tied her ankles.
Next came the hands.
I considered binding them behind her back to make movement harder, but it felt too far from my goal, so I tied them in front instead.
Still, I double-checked that it was tied tight enough not to come loose easily.
And now, the drug effect was almost up.
Fortunately, I'd managed to time it just right.
In the remaining moments, I thoroughly admired the 'younger sister''s body that I hadn't fully appreciated before.
Whether genetics or good care, the women in our family all had clear, pristine skin—and the 'younger sister' was no exception.
Her inner flesh was so pale it seemed translucent, temptingly luscious enough to take a big bite.
And the fresh, youthful skin scent wafting to my nose had my lower half reacting on instinct.
"Hng..."
The urge to fuck her filled my head, growing stronger by the second.
I was dying to know what her pussy looked like, what it tasted like.
"Ah, ugh... hng..."
Finally, a moan escaped as if she were waking from sleep.
Her body, tightly bound, squirmed futilely before her eyes snapped open in shock, staring at me in alarm.
"H-Hey! Wh-what the hell... what are you doing...?"
It wasn't the angry tone from before.
She looked up at me with a hint of fear.
"...What am I doing?"
"Y-Yeah... what are you... doing to me, kyaaaaaang!"
"Shh, shh!"
Earlier she'd screamed over a light tit grope, so this time with her pants already yanked down, she shrieked again.
"Hmmpf! Mmph!"
"Hey, Park Seo-hyun... won't you be quiet?"
"Mmph! Mmmph!"
This didn't feel like the moment to induce shame or whatever.
Should I feed her another Sleep Inducer, or just fuck her senseless to pin her down? I debated.
But putting her back to sleep wouldn't change anything, and even raping her now might not meet the completion condition.
After all, the requirement was to make the 'younger sister' feel Lust toward me.
Tip: Take off the panties and stuff them into 'younger sister' Park Seo-hyun's mouth to make her quiet.
A bit out-of-left-field tip, but I immediately hooked her pants and panties between my toes from between her legs and dragged them down.
"Ah, aaak! Hng... don't... bite my hand, haa..."
She bit down hard on the palm covering her mouth.
Not enough to tear flesh, but stinging enough to make my hair stand on end.
"Here, bite this instead... hng."
"Mmph! Mmmph!"
As expected, the tip worked perfectly.
She tried to scream, but with her mouth stuffed full of panties, the sound was muffled—no clear words came out.
I recalled the mission once more.
Use all means and methods to induce sexual shame and defile 'younger sister' Park Seo-hyun.
📍 Completion Condition: Activate the currently locked Lust toward me.
⏰ Remaining Time: 1 hour 26 minutes
It wasn't just about making her feel pleasure—she had to feel Lust specifically for me.
"First, I'll strip off that stuffy thing for you."
I slipped my hand under her back to unhook the bra I'd deliberately left on.
"Mmph! Mm!"
She squirmed to avoid my hand.
But that only made it easier for me to reach.
Click—the hook came undone, and the tension binding her tits slackened.
"Must be from Mom, huh? Your tits are fucking huge, right?"
I regretted mentioning Mom the moment it slipped out.
Unnecessary words, blurted without thinking.
"Mmmng! Mmph!"
But meeting her fiercely trembling gaze changed my mind.
I only had 1 hour 30 minutes left.
I really had to pull out all the stops.
"...Or maybe not? Seems even bigger than Mom's."
Lying flat, they spread to the sides, so not precise, but the firmness in my grasp was definitely superior.
"You know how much I've wanted to suck on these?"
"Mmph! Hngmph!"
Her frantic shaking made her tits jiggle beautifully.
And at the center, tiny pink nipples tempted me.
"Yesterday, when I was fucking Shin Ju-hee right next to you, you secretly wanted it too, didn't you?"
"Uh, uhhng!"
"You were awake. I know everything."
"Mmph! Mmph!"
"See this? I rammed it into your friend's pussy yesterday. Want me to shove it in yours too?"
I met the 'younger sister''s blazing gaze as I thrust my cock between her massive tits.
And squeezed the spread-out titflesh together.
Swoosh—swoosh—swoosh—
I could feel her heart pounding like it was about to burst right then and there.
