A Real Orgasm at Last
"Ugh... ungh..."
Oh Suyeong finally stirred awake, somehow.
*Squish*
As she rolled over from her side and lay flat on her back, staring at the ceiling, her bedsheets—drenched beyond limit—clung wetly to her ass.
And what had soaked those sheets was the massive pool of pussy juices she'd gushed out all night while furiously masturbating.
But she still had one big problem.
"Urgh... hnn... F-fuck, I didn't cum properly even once..."
Even after finger-fucking her pussy nonstop all night, she hadn't felt a single satisfying climax.
Whenever she did tip over the edge, it was just these weak little shivers—always leaving her wanting more.
No wonder she looked so wrecked now, her body hypersensitive to the slightest touch.
"Nngh...♡ Gotta... do rounds today..."
Still, with a full day of appointments ahead, Suyeong roughly wiped the sticky juices caked all over her body with wet wipes, then toweled off the moisture.
She threw on a fresh nurse uniform and headed straight to Minhyuk's room.
Today's schedule was packed from dawn till dusk. She couldn't exactly delay his checkups just because she'd edged herself silly without release.
Suyeong pushed open the door to his room.
There he was—Minhyuk, still fast asleep, unlike before.
She barely suppressed the urge to pounce on him right then, instead creeping closer and gently tapping his shoulder.
"M-Minhyuk...? Time to wake up..."
"Unh... grrrgh..."
Minhyuk stretched with a groan and sat up, tousling his messy hair into some semblance of order.
"O-okay, then... go wash up first and we'll talk? We've got a ton of tests today starting with the MRI, so no breakfast. You can eat lunch after that's done."
"How late will all these tests run?"
Minhyuk asked her flatly.
"Hmm... probably not till before dinner?"
"Got it... alright."
He climbed out of bed and headed to the bathroom.
Suyeong had no clue what he was getting at with that question.
Not during the MRI as he lay inside the machine.
Not during the X-rays.
Not even while checking his blood pressure or vision, standing right by his side—she kept racking her brain, trying to decode his words.
By the final pre-dinner check—a quick respiratory exam with the stethoscope pressed to his chiseled chest—she was half-giving up.
His attitude all day screamed it: he wasn't seeing her as a woman at all.
Even with this skin-tight uniform hugging her curves, her skirt hiked so high her panties flashed with every move—he showed zero reaction.
Not a flicker of interest.
Suyeong handed him his dinner tray with a dejected pout.
He wolfed it down in no time. Now there was just one thing left.
No more backlog tests. Time to figure out what that morning question really meant.
"All done?"
"Yeah, but... something's missing."
"Huh...? This is the standard portion, so I can't—"
"No, that's not what I—"
That's when it hit.
Minhyuk's eyes turned predatory, raking over her body from head to toe as he smacked his lips.
"Sis."
"M-me...?"
"Don't play dumb. You think I didn't notice you prancing around like that all day during checkups? What was that about?"
'Eh...? But he didn't show any physical reaction...'
"You have any idea how hard it was holding back?"
His words jolted her awake, like fog vanishing from her mind in a rush.
"Forgot the bet already? If I shove my cock in your pussy, you lose."
"..."
"Anyway, the bet doesn't end tonight, so if you want, I'll play along. But whether I fuck your pussy or not? That's all on you. Your call."
He stood from the bed, brushing past her with a hand on her shoulder, pausing before the bathroom to drop one last line.
"Oh, and if you're coming tonight... bring the stethoscope."
"...Yeah."
Minhyuk flashed a grin at her shy reply and left the room.
How she'd take it was entirely up to her.
"Heh...♡"
And her answer was already clear.
"Hmm... she'll show, right?"
Honestly, I'd just tossed it out there with a whatever-happens-happens vibe, telling Suyeong sis straight-up to come if she wanted.
Truth was, that red garter belt squeezing her thighs all day had me dying.
"If she shows up in that outfit... I might just pin her down myself..."
Lost in fantasies, I heard a knock right before 8 PM.
*Knock knock knock*
"Yeah. Come in."
The door creaked open cautiously, revealing Suyeong sis.
'...!'
I couldn't help but stare.
She stood there, arms crossed under her massive tits to thrust them out.
But that wasn't it.
No nurse uniform.
Just the crimson lingerie set and garter belt I'd secretly hoped for, stethoscope draped around her neck, eyes boring into me.
Even from here, I could feel the raw lust burning in her gaze.
My cock sprang to attention in response, pitching a tent under the sheets.
Her lips twitched at the sight.
This could end the bet tonight if I wasn't careful.
But no—my goal was to blue-ball her sis till tomorrow night.
If I slammed my dick in first, the whole plan went poof.
Couldn't just raw-dog her ass unprepared either, so tonight it'd be tits and mouth only.
'Still beats jerking off solo.'
I beckoned her over like summoning a minion.
"Come here."
"Y-yes..."
Her polite honorifics slipped out at my command tone—already bending to my will. My cock wept pre-cum in excitement.
She slid into my right side, snuggling into my arms, curling up cutely with her arm around my waist.
But we had work to do.
"Bed later. First, straddle me."
"Okay."
I spread my legs wide; she mirrored me, lowering herself on top, legs splayed.
Her panties were already soaked through, pussy drooling.
*Schlick*
"Turned on?"
"Hoooh♡ Yesss♡"
"Body's honest, words too. Perfect."
"Hehe...♡"
She giggled like an idiot.
I slipped the stethoscope earpieces into her ears, pressing the diaphragm to her pussy mound with my left hand.
"Eh...? What's th— Hiiiyaaah♡ Aghh♡"
Before she could react, my right hand yanked her panties aside and plunged in, finger-fucking wildly.
The wet *squelch-squelch* echoed live through the stethoscope into her ears—physical bliss plus audio overload. Her hips bucked, pussy clenching desperately.
"Just fingers and you're cumming already?"
"Haa♡ Nooo♡ Didn't cuuum♡ Hooooh♡"
A light G-spot scrape with my fingertip, and she melted into ecstasy, cumming again.
*Squelch squelch squelch squelch*
I didn't stop; she thrashed to escape, but my legs pinned hers—trapped.
"The sooound♡ Ears♡ No moooore♡ Pleeease♡"
Minutes of helpless torment later, I yanked my fingers out. Her pussy erupted, squirting pent-up juices in a geyser.
*Pssshhhhooooosh splurt splurt*
I'd seen plenty of squirts, but hers was the biggest yet.
How long had she held back? Her orgasm dragged on forever.
Nearly a full minute of beastly moans, squirting nonstop—till she pissed herself at the end. Then she went limp.
"F-fina... lly... ca... me...♡ Real cum♡"
She mumbled through lolled tongue, slurred beyond comprehension.
But her ahegao face held a faint smile—she was loving every second.
Good news, since we had a long way to go.
