Lullaby Lullaby, Our Dick~
"Haa... haa... haa..."
"Hey, you okay? You seem pretty tense. If it's that bad, want me to take over?"
"Ah, j-just stay still! This isn't my first or second time doing this! Why do you keep nagging like that!"
Hyeonju snapped back with a prickly glare, clearly feeling a bit guilty. She'd told him to just lie there and do nothing, but she was the one dragging her feet and wasting time, leaving her without much to say in her own defense.
Of course, even Hyeonju had her excuses. Cowgirl sex—where the woman straddles the man below and rocks her pussy on her own—was way harder than it looked. Unlike regular sex, where the guy could just thrust for his own pleasure, this required scouting out his sensitive spots first. And she had to do it with a cool head, which was the real killer.
Hyeonju lost herself the second a finger went in, turning into a brainwashed pervert sister who adored her brother. Straddling his cock? Forget it.
But excuses wouldn't fly here. "Still, you do this every time. Doesn't that mean there's a problem?"
"N-no... that's... um..."
She was cornered by his airtight logic. Why is this guy so annoyingly rational only when it suits him?
"I'm getting tired of this routine. Let's try getting serviced properly this time, wide awake. Maybe lower the sensitivity a bit..."
He muttered something cryptic and fiddled with his smartphone. Right in front of his sister's delicious pussy, and he's playing on his phone? This jerk has zero manners.
"Okay. This should let me enjoy it at a normal level. Alright, let's get started. How long you gonna stall, huh? Scared or something?"
"Ugh... who're you calling scared...! I'm not scared! Who said I was?! Y-you're done for! I'll make your hips give out!"
She bluffed big. No backing down now—it was all or nothing. Hyeonju squeezed her eyes shut and slammed her hips down, swallowing Oppa's cock whole into her pussy.
His thick shaft pierced her tight walls in one go, blasting her brain with ecstasy so intense it lit up her skull like fireworks.
But... Huh? That's... not as bad as I thought?
The blissful pleasure surging through her body was irreplaceable, unmatched by any other thrill in this world. But it wasn't the all-consuming, addictive high that erased her sense of self like before.
Weird. Hyeonju chalked it up to her hard work finally paying off.
All that masturbation practice and porn study is shining now! My head's still spinning from how good it feels, but I can handle this. Yeah! Now I can proudly spread my pussy in front of this guy! Finally!
"Hey, what's with the pause? Weren't you gonna wreck my hips? Just twitching your pussy walls won't cut it. Move already. Where's that lullaby sex at?"
"Hmph! I was just about to! So impatient."
Hyeonju shot back sharply, but inside, she was soaring. She slowly pulled off his root-deep cock, then sank back down just as leisurely. Sweet moans slipped out unbidden from the pleasure radiating from her pussy, but compared to before, it was nothing.
Her pussy stayed honest, though, drooling juices to testify how delicious Oppa's cock was. That balance satisfied him perfectly.
"Alright, here we go? Lullaby sex. Close your eyes so you can sleep soon."
"Okay~ Take good care of me."
Oppa spread his limbs wide and shut his eyes. Seeing him so comfy irked her for no reason. Siblings must be born with some biological curse like this.
Whatever. Hyeonju relaxed, gently bobbing her hips up and down so he could savor her pussy, and started singing.
"Lullaby~ lullaby~ our dick~ come into little sister's fuckhole, snooze~ lullaby~ lullaby~"
Lullaby sex wasn't much different from regular sex. The woman took full control of the cock, rocking her pussy to the slow, sleepy tempo of a lullaby. No movement from the guy meant no workout to chase away sleep—just cozy body heat, snug pleasure, and drowsy rhythm lulling him under.
It was common knowledge now that nothing beat lullaby sex for putting boys to bed. Mom must've slacked on it back in the day, so Oppa got hooked late and always demanded it from Yu-ran or Hyeonju at bedtime.
From Hyeonju's view, it was Mom's laziness dragging her into this hassle too. Not that she'd ever blame or badmouth her for it.
"Mom's pussy yesterday~ sister's pussy today~ whose pussy tomorrow~ sweet dreams, then off to another fuckhole~"
"Ooh... yeah. Really feeling sleepy now. Heh, that song especially. Who the hell came up with those retarded lyrics?"
Hyeonju wrinkled her nose and glared. Just go to sleep already if I'm doing lullaby sex. Why so much chit-chat? Who wrote the lyrics? Some old-timer, duh.
She almost snapped back but swallowed it—wouldn't want to break the rhythm.
"Dream of training cock-food pussy~ or fucking arrogant pussy~ nnghaaa♡"
The problem wasn't just his attitude. She'd barely clung to sanity, but the male superiority pulsing from her pussy was unchanged. Oppa hadn't cum once, yet her pussy was already on its fifth orgasm. A reminder she had a long way to go.
He's insanely strong in this department.
"Whoa, what's wrong? Surrendering already? Kinda disappointing. Huh?"
Oppa smirked up at her, face screaming, I know everything—give up already.
Hyeonju wasn't mature enough to let that slide.
"As if~! You think I'd surrender?! No way I'm losing! You think I'm some pathetic fucktoy who can't even do lullaby sex right?! Let's see who wins!"
She gritted her teeth and shook her pussy wildly. It strayed from lullaby sex's gentle vibe, but if Oppa was happy, who cared?
But her frenzy backfired. Too focused on draining his pleasure, she ignored her own.
And the result?
"Nngheeeek♡ Ahhh, nooo! Doing it this hard makes me cum nonstop! Pussy won't stop cumming! This is bad, stooop♡"
She was barely holding her last thread of sanity, but it was visibly fraying. If it was that dangerous, just stop shaking—but easier said than done.
As Oppa's fucktoy at heart, Hyeonju's body was programmed to obey him absolutely, no matter what bratty words came from her mouth. So even as she protested, her hips only rocked harder.
"Sheesh, so loud. Scream like that and I'll wake right up. Can't you be quiet?"
Oppa chuckled, mocking her without lifting a finger. What a dick.
"Aang~♡ But Hyeonju pussy's at its limit already~♡ Sorry, Oppa. But Hyeonju pussy's in real danger now. Can't you punish it hard with that cock? Pleeease?"
Oh crap. She'd thought she was holding strong, but her pervert sister side slipped out unnoticed.
Oppa gave a dumbfounded chuckle. "Aigoo, shoulda lowered the sensitivity more? This girl's mental barriers are crumbling daily. Not that I mind since she's cute."
He muttered something incomprehensible, grabbed her hips, and yanked her forward. Her body toppled helplessly onto his chest.
"Just receiving service is getting me antsy. Gonna pound that pussy to ruin, so brace yourself. Got it?"
"Yesss~♡ Hyeonju pussy exists for Oppa. Pound my slutty dog-pussy however you want, enjoy it raw, and sleep refreshed~♡"
What a cute little thing. Oppa crushed her like a bear mauling prey and started pistoning fast into her pussy.
Looked like it'd be hours before either of them slept tonight.
