Service Training (9)
In one gulp, she swallows Seongjun's cock all the way down to the root.
She sucks and pulls like she means to rip it clean off. The skin of his shaft folds and bunches as it vanishes into her mouth. In an instant his balls clench tight, and something surging and heavy races up the length of his cock and shoots free.
His little sister looks up at her own older brother through half-lidded eyes. She clamps her jaws shut around him. He seizes her head in both hands and locks on hard.
"Nnngh!! Dain—fuck...! Oppa's gonna—I'm gonna cum!!"
"Mmmmphhh!!"
The smooth flesh of her throat wraps his entire cock and clings to it. She chews and works him with slow, grinding pressure. He can't hold it anymore. At the deepest point of his little sister's throat, the darkened slit of his cockhead flares wide open. Unresisted, supercharged cum ignores gravity entirely and blasts out at the speed of light.
"Aaaahhh!!"
Her head snaps backward. She wrenches her mouth open so wide it looks ready to tear, drool and foam spilling down her chin. Her whole body twists and contorts on its own. She shudders violently, trembling like a leaf in a gale. From the seam where cock and lips meet, a thin white liquid spurts out in a sudden spray.
"Aaaah...! Aaaah...! Aaaaahhh...!!"
"That's it, keep sucking it down just like that."
Eunbi presses hard on the back of Dain's head, burying her face in her older brother's crotch. Dain gags. She braces with both hands, fighting to endure it. Every last drop of cum still clinging to his cock gets wrung out into her throat. She pants for breath. The crash hits her all at once.
She did it. Right in front of someone else, she let her own older brother cum inside her mouth-pussy.
"Haa...! Haa...!"
"Roa? Spit the cock out. I want to see how much cum you swallowed."
"Pwahh...! Like... this?"
Seongjun's cock springs free of his little sister's lips like a released coil. It hasn't softened at all. The shaft stands straight up toward the ceiling. Dain's cheeks are slightly puffed. Her throat works with a visible swallow. She swallowed it. She proudly shows off her tongue, painted white.
"Damn... Roa, you're good at this. Cum's pretty drinkable, right? Customers go crazy when you do this for them."
"Yeah, unnie... Oppa seemed to like it too."
"Hehe... You've gotten pretty slick already. Nothing left to teach you... Good work. I'll put in a good word with the boss and the manager."
"Is that it? Are we done?"
"Hm? What's wrong?"
"I'm not satisfied yet."
Unbelievable bullshit comes tumbling straight out of Dain's mouth. Fuck—she drained him dry and she's still not satisfied? They already finished the blowjob and the rimming. That means they've done everything short of actual penetration.
The corner of Eunbi's mouth curls up. Without the slightest hesitation she drives two fingers straight into his little sister's pussy. The filthy little bitch who already knows exactly what that means shoves her ass back to help the fingers go deeper.
Thwack!!!!!
They sink in to the root in one thrust. Eunbi churns them hard. His little sister surrenders her whole body to Eunbi's fingers and lets out a moan thick with pleasure. Through half-glazed eyes she looks up at her older brother.
"Ahaaang!! Oppa...! Nngh...!"
"Roa... You want to fuck? With your own older brother...?"
"Yes! I want to, unnie...! Ahaang...! Nngh!!"
"Oh my... You should've said so sooner... Honestly, unnie was feeling a little unsatisfied too... That bastard's cock and your pussy... they look perfect together."
"Ahhng...! Harder, unnie... It feels so good...! Kyaah!!"
"Hehe... Can't do that... If you dig around in a pussy wrong you can hurt it, you know? Let your big brother's soft cock soothe that pussy instead... Roa..."
Eunbi's fingers, buried between Dain's ass cheeks, slide slowly back out. Sticky fluid clings to them in long, stretching strands that bridge her fingers to the pussy.
"Haa...! Haa...!"
"Can I eat that pussy?"
She gives a small nod. She doesn't even stop to think before granting her older brother's request. Slowly she rises, turns her back to Seongjun, and lowers her ass toward him. Gel and pussy juice mixed together leave her gleaming and slick. A damp, humid heat brushes against her older brother's face. Closer and closer.
It's big. His little sister's ass. Plump and springy. He grabs it with both hands. Her whole body gives a hard flinch. He spreads the cheeks wide. Her ass twitches and sways as if trying to resist. He opens his mouth wide and sticks his tongue out, waiting for his little sister's pussy to come to him.
Contact.
"Ahang!!"
Seongjun's tongue nudges the outer lips of his little sister's pussy aside and drives in. She sits all the way down. Pussy juice trickles freely, soaking his tongue. It's honey. He receives the little-sister pussy he had only ever dreamed of. Wet, sucking friction sounds fill the air as he loses his mind completely, clamping both hands on her ass and greedily licking and sucking.
"Haa... This pussy tastes so fucking good... So this is little-sister pussy... Sweet, fragrant smell..."
"Hehe... You filthy bastard, when you talk like that it really does sound like you're eating your own little sister's pussy... Doesn't it?"
"Yeah, think of it as the real thing... Haa... Feels like a dream... Even the color's pink..."
"Roa? How does it feel having that bastard eat your pussy?"
His little sister bites down hard on her lip and shakes her head side to side, fighting with everything she has to hold back the moans trying to burst free. Her glistening lips part just a little. A lewd whimper slips out.
"Ahaang...! Oppaa...! Nngh...!"
"You suck your big brother's cock too... You've already done it, so you can handle it, right?"
"Oppa’s cock... feels even bigger, unnie... Nngh...! Aaah...! Right there, more...!"
With her ass still buried against Seongjun's face, she grinds in slow circles. She's completely gone. Her older brother's cock, flushed dark red, sits right in front of her eyes and she doesn't care at all. Every nerve is locked on the tongue plunging into her pussy. Eunbi can't watch anymore and guides Dain's hand onto the cock. She grips the shaft tight and starts stroking on pure instinct.
Slap! Slap! Slap! Slap! Slap!
The swollen red cockhead fills his little sister's vision. She opens her lips wide and swallows it. She lifts her head. The veined shaft slides free. She drives back down. It disappears completely. The outline of the cockhead stands out clearly against the back of her neck. She sucks like a woman possessed.
"Little-sister pussy... Little-sister pussy!! Fuck, it tastes so good... Honey's dripping off it!"
"Haa...! Haa...! Oppa's cock is too big... It won't all fit in my mouth... But I love it so much... Oppa..."
Blood-related brother and sister, completely naked without a single thread on them, suck each other's sex. Eunbi watches the whole thing. She swallows hard. She wants a closer look. She drifts toward Seongjun's head and leans in until she's almost touching. The sight of an older brother greedily eating his little sister's pussy looks almost beautiful to her.
"Hey. Taste good?"
"Yeah, fucking kill me... I've never tasted a pussy this good in my life."
"What'd you say your little sister's name was again?"
"Dain... Lee Dain. Twenty."
"Come to think of it, that's the same age as Roa, isn't it? You even said they look alike."
"Haa... Haa... Yeah, I did. Hearing it again makes me even harder... Fuck."
This time Eunbi drifts over toward his little sister's head. She holds her breath and watches Dain drag her tongue from the base of the shaft all the way to the tip. With the soft flat of her tongue she gently licks her older brother's cockhead. Jealousy stirs. Envy.
"You call your oppa's name too, Roa..."
"Nngh...? You want me to say his name...?"
"It'll turn you on more that way..."
"It's a little weird..."
"It's fine. That bastard already used his little sister's name... He said Dain."
"Haa...! Haa...!"
"Oh my... Why the sudden reaction? Don't tell me... you know that name?"
Eunbi's finger slips between his little sister's ass cheeks and taps lightly against the twitching ring of her asshole. A rush of insane excitement rips through Dain's head. She lets go of the cock she'd been sucking. Strength drains from her hands.
"Aaaah...! Unnie...! Nngh...! Oppa...!"
"Don't tell me... your real name is Dain...? Same age... look alike too... Hm...?"
"Nngh!! Ahaang...! Aaaaang!!"
The finger pushes into her asshole. She thrashes trying to pull free, but Seongjun has her ass locked in a tight grip and she can't get away. Drool spills freely from between her glistening lips.
"Was that too much? I was just asking to get you hot... Sorry..."
"Haa...! Haa...! It's Lee Seongjun, unnie..."
"Hm...? Seongjun...? I feel like I've heard that name somewhere..."
His little sister wraps both hands around Seongjun's shaft. She expertly works the darkened cockhead with her tongue. Something sharp and electric digs into the slit of his cock. He clamps his mouth shut—and accidentally bites down on the outer lips of his little sister's pussy.
"Nngh...! It's Oppa... My real older brother..."
"What are you talking about...? Real older brother...? Who are you talking about...?"
"This... is my real older brother's cock... Unnie..."
"What...?"
A faint smile spreads across Eunbi's lips. At last she said it herself—that he's her real older brother. Eunbi already knew everything. She gently brushes Dain's hair back from her face. All the pieces are in place.
"Come to think of it... this bastard said his name was Seongjun too..."
"That's right, unnie... He's my real older brother..."
"Hehe... What kind of coincidence is this... So that means a real older brother and a real little sister are naked together right now...?"
"Haa...! Haa...!"
"While you were sucking each other's pussy and cock... what were you thinking...? Hm, Dain...?"
"Ahaang!! Oppa!! Not there... Nngh!!"
Seongjun's fingers drive into his little sister's pussy. He pulls them back and then rams them in hard, punching through. At the same time his tongue flicks the outer lips upward. He licks up every single drop of the pussy juice streaming down—not one wasted.
"Dain... This pussy tastes so fucking good... This is real little-sister pussy... Mmm..."
"Oppa...! Ahaang...! Seongjun oppa...!"
"Yeah. You calling my name gave me the courage... I'm gonna eat my little sister's pussy properly... Dain..."
His little sister's upper body jerks upright. She goes rigid, head thrown all the way back, and lets out a scream mixed with a moan. Her watermelon-sized tits bounce wildly. Eunbi doesn't miss the opening—she grabs one in each hand and kneads them, breathing hot against Dain's ear.
"Your oppa's eating his little sister's pussy like a gourmet meal... Hm? I'm jealous, you filthy bitch."
"Ahaang...! Unnie...! Nngh...! Aaaah...! Oppa eating my pussy feels so good!!"
"You little slut... Are you mocking me right now?"
"Oppa’s cock is too big...! It's so hot I feel like I'm gonna burn!! Unnie...! Nngh...! Ahang!! Nngh!! Ang-ang-ang!!"
His little sister's ass goes rigid, locking up tight. Her older brother's fingers slide free. Her pussy gapes and clenches madly. Pussy juice drips straight onto his face. He sits up.
"Dain... I want to do it from behind..."
"Haa... Haa... From behind...?"
"Yeah, that okay? Eunbi's here so nothing bad'll happen... Don't forget what Oppa told you earlier..."
"Hehe... That fucking bastard, I can see right through him... He's planning to grind his cock against you from behind and then shove it in."
"......"
"Is that true... Oppa...?"
"Look at that, he's gone completely mute... That bastard's going to pretend to rub against you from behind and then fuck your pussy raw."
"...I want to."
"Hm?"
"I want to do it from behind, Oppa... But you can't put it in without my permission... okay?"
Dain casually ignores Eunbi's warning. Seongjun's head tips in a small nod. The corner of his little sister's mouth curves upward. Slowly she gets down on all fours. She drops to her knees. She pushes her ass back toward him. She spreads her smooth legs wide and settles into a perfect doggy-style position.
