Lee Hayun Craves Big Sister Treatment (8) - You Who Wanted to Play Big Sis, How Far Will You Allow?
"Chup... Nng... Hahp...."
Lee Hayun lay obediently on the bed like a dog at my command, her body prone and waiting. I grabbed a fistful of her hair, yanking it back as I shared breaths with her. Her back was arched to a degree that should've hurt like hell. But thanks to her transcendent abilities—and probably all that regular training—her spine bent with flexible grace.
Over that supple curve, her slack-jawed mouth hung open in a daze, and I flooded it with saliva.
...While thrusting my hips all the way in.
Just like that, pounding relentlessly at her weak spot.
"...Pha, haa...."
When I finally pulled my lips away, Lee Hayun's utterly wrecked face filled my vision. Her cute, un-big-sis-like features were smeared with confusion... her face heaving with ragged pants.
...I wanted to shatter it completely, until every trace twisted into pure ecstasy. Swallowing that thick, muddy urge, I let out a satisfied sigh and pressed down on her back.
No mismatched cowgirl nonsense. She stayed prone on the bed, ready to take it like a bitch in heat.
"Huu...."
"......?! ...♡ ........"
Thud, thud, thud.
My cock, trapped in that frustratingly tight convenience store condom, hammered the deepest part of her. Slowly. But deep.
Careful not to knock her out completely. So she'd remember every second of this crystal clear.
Even after sex ended, after we parted with awkward haha's and hoho's, this infirmary romp would haunt her thoughts all day.
I pulled out my slick, drenched cock—coated in sticky juices—and slid back in. Slowly. But deep.
Ignoring her foot tapping the bed in surrender, I shoved deep into her core until our soaked bodies slapped together messily—my lower abs against her dripping ass.
Her underdeveloped pussy clenched tight, resisting entry, but who cared. I'd break her in bit by bit, ramming as deep as possible while watching her twitch and climax.
...Any normal girl would've screamed in pain and fought back.
But not her. Instead of resisting, she squeezed so goddamn tight it drove me insane, milking my cock like she was begging for more.
What if she'd never met me? What if she'd hooked up with some nice, fun, talented hero and built a sweet romance? What if his average dick left her clueless about her own pleasure zones her whole life?
Swallowing the boiling conquest, I yanked her long hair again.
"Nnghk....... Hey, wait, hold on...!"
She'd been twitching obediently with her face buried in the pillow, but when I tugged her neatly tied ponytail—apparently annoying her—she shot me a glare and growled...
...Only to go meek in an instant.
"Ah.... Uu...? Nng.... Hic...."
Because she'd lifted her body herself, letting my cock plunge even deeper. Pressing her ass firmly against my abs. So hard that wrinkles formed in her crushed flesh.
Deep.
"Lee Hayun."
"Wh-what.... No, to your big sis, don't you dare...!"
"Lee Hayun."
"Nngt...?!"
With her hair gripped like a leash, she clawed at the bedsheets in prone submission. I pulled her up into my arms, nibbling her flushed ear as I whispered.
"...Still wanna hear 'big sis'?"
"Of course.... I'm your big sis, after all...."
Squelch, squelch, squelch... I stroked her belly—still getting tamed hard—feeling it bulge faintly under my palm.
"...Doesn't this feel very 'big sis' to you?"
"......"
"Answer me. Doesn't feel big sis-like, right?"
"...U, ungh...."
On the creaking bed, amid her bitch-in-heat pants, I demanded answers. And to shut down any bullshit—
Thwack, thwack, thwack—I battered her weak spot until it was mush, until her head lolled and her hips bucked wildly.
"Remember? When we first met..."
"Hahk.... Hak.... Nnguk...."
I tossed her a little noose.
"...You called me 'oppa' back then."
"...I. Remember, no......."
A clumsy little snare for a cute country pup.
"Then remember what you said after?"
"Dunnooo.... How am I supposed to remember all that...!"
I didn't remember exactly either. Hell, I couldn't even recall my chat with the principal minutes ago word-for-word.
But I didn't need facts. Just the vibe.
"You promised to call me 'oppa' next time you got healed."
"...? M-me?"
"Yeah."
"...?"
I strung together vague memories with whatever words fit the moment.
"No way...?! Uht, w-wait...!"
I hammered her defenseless pussy relentlessly. Thwack-thwack—each thrust flipped her switch, sending her over the edge. Ignoring her drooling tongue, the dripping juices staining the bed, her tightening walls screaming for mercy—splurt, splurt, thwack.
Until she couldn't think.
"I just healed your finger..."
"Stop.... Wait, stop, pleaseee...."
"Keep. Your promise."
"No way......!"
"It's not a big deal, right?"
"What... O-oppa...! You're my little bro...!"
"...Don't wanna?"
"Never, absolutely ne—...!"
I yanked her leash—her hair—tight, slamming thud-thud-thud-thud into her vulnerable womb mouth.
"Even like this?"
"No, I said nooo......!"
...As expected.
Too soon to crush her big sis cravings completely. A shame.
"Then arch your back properly. ...Don't let it sink."
"......"
Fine. Plenty of chances ahead.
I grabbed her panting, tongue-lolling jaw and plunged back in with a sloppy kiss, thrusting deep. A few stray black strands escaped her ponytail, mingling with our saliva. I licked her sticky tongue alongside them, gulped down the sweet mix, then gripped her slack hips and pounded—paang, paang—until only vulgar slaps echoed.
Her long-neglected pussy, sopping wet and ready. I punished the deepest spot.
Over and over.
Thud, thud, thud.
Shoving my beastly full-length cock to the hilt—unfitting for her bubbly self—until her crude moans filled the infirmary. Until her flailing arms dragged a pillow under her face. Until I was right on the edge.
Relentlessly.
"...Lee Hayun."
"......"
She managed to lift just her ass as ordered, face smashed into the pillow, gasping.
I tugged her hair gently and whispered.
"Cumming. ...Deep in your pussy."
"Hahk... Hak.... Whatever, condom...."
"...Threw it out."
"...Wh-what...?"
"Didn't fit. Tossed it."
"......Wh-when...."
"When I pulled out for a sec."
"Pulled...? We've been fucking non-st—."
Grinning wickedly, I pressed her head softly into the pillow. No more words. Just confusion piling on confusion. Her own scent from the soaked pillow. Make her think she was pinned down, bred raw by my bare cock...
"Huu...."
"..., ......! ......?!"
She collapsed fully onto the bed, hips arched just enough. I mounted her, paang-paang-paang... until she was truly flat. Glaring at her slapping ass, I rutted like animals.
Until the thick cum boiled up from my root to the tip.
Paang, paang.
Desperate to block a creampie? One hand that had been clawing the pillow now shoved at me weakly.
...Pointless without her powers. Was she playing along to excite me, knowing it was bullshit? Or did she really fear the creampie?
Shoving those thoughts aside, I crushed her head down—hard—into the pillow. No voice, no breath escaping.
Hard.
"Kuhk...."
"......, ..........♡"
Splurt, spluuurt, splurt-splurt, spuuuuurk.... Matching my pulsing release, her insides convulsed in orgasm... inside the condom barrier between us. I smeared it with cum-stink and crushed her head down.
"...! ......, ......?! ...."
Her pushing hand flopped limply, twitching on the sheets. She'd climaxed with my load, no signs of recovery.
Wonder how broken she was now. Cleanup fellatio, maybe?
Fun thoughts aside, I eyed her twitching fingertips and slowly withdrew.
My juice-soaked cock slid out of her... but oddly, no condom tip appeared—just bare, slick skin emerging. Only when the glans popped free did a pink trace show.
"Relax. Hayun-ah."
"......"
"...Can't? Well, nothing for it."
The condom clung precariously to my glans tip, caught inside her while my cum-filled shaft slipped free.
"Stay still. I'll pull it out."
"......"
Lee Hayun said nothing. Even in this lull, face buried, just twitching.
From between her legs, I carefully extracted the cum-bloated condom. Abnormal volume made it heavy in my hand.
Lucky it didn't tear...
...Anyway.
"...Lee Hayun."
"......"
Post-climax, the bed had cooled. I called her name again—no answer.
Not passed out; I'd seen her toes wiggle. Not crying either.
Just face-planted, ass twitching silently.
"Get up. Time's almost up. Class in an hour, right?"
"......"
Her "hour" was down to minutes. I wanted to push more, but satisfaction here.
Not zero gains, though. The girl dying to play big sis got dog-fucked to oblivion by her "little bro." Her head must be spinning.
Keep this up, and we'd hit something even more "fun" soon.
Smirking secretly, I buttoned my shirt.
"Or is it 'cause I'm talking casual? That why you won't get up?"
"......"
"...All just roleplay, y'know. Did it bother you?"
"......"
"Sorry. Thought you liked it since you seemed into it. Figured big sis secretly digs it too."
"......"
"Guess not."
"......Didn't like it."
"Huh?"
"I said I didn't like it...! Felt bad."
She shook her head lightly, sitting up. Wiping drool from her mouth—cheeks blazing red.
......Her true feelings were obvious.
"...Seo Woojin."
"Yeah."
"N-never do it again. That stuff."
"What stuff?"
"What we just did."
"Just now...? The position? Or pulling your hair?"
"N-not that—something more important...!"
"More important...?"
I played dumb, dragging it out. She fumbled her shirt buttons like me and snapped.
"C-calling you... o-oppa...."
"...Should I skip it next time?"
She nodded furiously, sweat-slick face set, lips sealed tight. No more words.
Blissful silence fell. Just belt jingles from my pants, shaky hands buttoning up.
No threats of punishment for my cheek next time. No whining about the wrecked bed.
15 minutes left. Amid the quiet, ponytail retying, she mumbled.
"...B-but."
Gown on, I straightened up and glanced over.
"Not 'never' for everything... j-just... that part. ...Yeah."
"......"
She babbled, but I got it.
Doggy? Fine. Hair-pulling? Fine.
But "oppa"? Never.
"...Walk you out?"
"N-no need. Escort what...?"
"You begged yesterday."
"That was then. This is now...!"
"Ah, buttons're off. Top one's wrong."
"Eh...?"
"Bottom too, probably?"
"......"
How long you gonna hide it?
After a grueling three-hour raid, the boss tormenting the newbies finally dropped.
Clear achievement popped, and Discord exploded with voices: "Fucking finally got the bastard," "Head hurts too much, quitting this game," "Three hours? Real pain's four hours a day for a month,"—veteran flexing bullshit.
Anyway, noisy as hell. Lee Jiyoon pulled off her headset for a breather.
"......?"
She frowned at the odd sensation.
...Her head hurt.
