Service Training (8)
My vein-ridged cock twitches like mad. The heat pouring out of my little sister’s pussy brushes against her big brother’s dick. The two of us siblings freeze mid-motion, panting hot breath into each other’s faces. Our eyes lock.
"Haa…! Haa…!"
"Haa…! Haa…!"
Eunbi watches the place where cock and pussy touch with a thoroughly pleased expression. She picks up the lube bottle and squeezes a long bead of it right into the cleft of Dain’s ass. The cold sensation sinks in. Dain’s hips sway gently side to side. At that almost-touching distance, her big brother’s twitching cock brushes her crotch and then pulls away again.
"Ugh…!"
"Ahaang…!"
"Hehe… You two look so good hugging like that…"
The hand that has been wrapped around his little sister’s back finally starts to move. It caresses her softly, sliding lower and lower until it reaches the narrow dip of her waist. Fingertips skim across the skin. Dain’s hips jerk upward and then sink back down, limp. She still hasn’t broken eye contact with her Oppa. A lewd little moan slips free.
Eunbi pushes a finger into the cleft of Dain’s ass.
"Aeuung…! Unnie…!"
"Haa… Both of you are pink… cock and pussy alike…"
She strokes up and down the cleft, over and over. Dain’s whole body gives a big, startled jolt. Without thinking she clutches her Oppa’s body tight, plastered against him. Clear fluid starts to drip from the pouting lips of her pussy, soaking her big brother’s balls. Her ass clenches hard, then plumps back up again. That pussy is begging for cock.
Catching on at once, Eunbi pinches the outer folds of the twitching pussy with both hands and spreads them wide open.
"Stop it, Unnie!! Uuung…!"
"Wow… Your pussy is fucking gorgeous…"
"Haa…! Haa…!"
"Oppa’s cock is right in front of you… What should I do with it? Just shove it in?"
"No!! Anything but that…!"
Dain clamps her pussy hole shut. She has no control over Oppa’s cock right now. If Eunbi felt like it she could grab that dick and drive it straight into her. She has to stop this.
"Oh my… Getting all angry out of nowhere… I was only joking…"
"Haa…! Haa…! That was mean, Unnie…"
"Hehe… It’s because you keep stalling instead of starting the service… Come on, hurry up…"
Dain’s tongue flicks out. She drops her head and flicks her big brother’s stiff nipple upward, then starts sucking on it greedily, licking and tasting like she’s savoring a treat. Seongjun’s twitching body is all the proof she needs.
"Uuugh…! Fuck, that feels amazing… huh?"
"Haa…! Haa…! You like it…?"
"Yeah. Even that glare of yours is fucking hot… You’re doing great, just keep going like that… I’ll put in a good word with the manager for you."
Eunbi’s hand glides up Dain’s back, stroking down smoothly while her other hand keeps teasing the cleft of her ass. She’s pouring everything into getting her worked up. The tightly closed pussy hole begins to open little by little, dripping juice, already a little swollen.
The little sister’s tongue travels lower, past the nipple, across the side of his ribs, until it reaches his navel. She gives it a light kiss. Something rough tickles her chin—pubic hair. She ignores it and keeps going. Scorching heat brushes her cheek, rising straight off his cock. Her heartbeat races out of control. Then something that feels like a furnace touches her. She looks. The cockhead has turned bright red. She swallows hard.
"Don’t stare at it like that… You’ll make him self-conscious…"
"Haa…! Haa…!"
"Hehe… Roa…"
"Yes, Unnie…"
"You saw earlier… Doing it with my real Oppa is my fantasy, you know…? What about you…?"
The finger that has been sliding in and out of Dain’s ass cleft pushes through the slightly parted pussy lips. Dain’s head snaps up and she lets out a scream-laced moan.
"Kkeuhaang!!"
Her ass clenches hard. The finger buries itself to the root, wrapped tight by the bumpy inner walls that cling and chew on it.
"I’m asking you, Unnie… Have you ever imagined doing it with your real Oppa…?"
"Never… Uheung…! Ahang!! Unnie, it’s too deep!!"
Eunbi’s finger pulls back and then drives in hard again. Pussy flesh drags out with it before the finger sinks back between her cheeks with a wet sound.
Thud!!!!!
She rams it all the way to the base in one go, focusing on the round, swollen spot she’s already figured out is Dain’s sweet spot. She presses it firmly.
"Aheung!!"
"Really… You’ve never imagined it…?"
"I haven’t, Unnie!! Stop… Aaaang…! I’m going crazy!! Kkyahang!!"
"Hehe… Our Roa… You’re so sensitive, aren’t you? Come on… Suck it. Oppa’s cock looks like it’s suffering…"
Seongjun flexes his cock so it nods. His little sister’s head is right there, almost touching. She stares at her big brother’s dick like she’s trying to burn a hole through it.
"Suck my cock."
"Oppa…"
"Last time you only stroked it… I want to taste that mouth-pussy of yours…"
The little sister’s lips part slightly, aimed at her big brother’s cockhead. She leans in slowly. The cockhead, so red it’s almost black, slides between her glistening lips.
"Kkeueuk!!"
Mind-melting excitement races through my skull and a scream tears out of me before I can stop it. My little sister just sucked her Oppa’s cock. This is only the beginning. The cockhead disappears completely. The vein-ridged shaft vanishes after it. She swallows him to the root.
"Uuup…!"
The shape of the cockhead stands out clearly at the back of Dain’s neck, bulging. Eunbi focuses her attack on Dain’s ass and pussy, caressing gently while she pulls the finger out of her cunt and then rams it back in hard, never forgetting to press that swollen spot.
"Kkeuheok…! Fuck, finally getting that mouth-pussy… huh? You should’ve done this ages ago… Ugh!!"
"Does it feel good having Roa suck your cock?"
"Yeah, it’s incredible… Feels like I’m buried in pussy."
"Hehe… Roa, you hear that? He says your mouth-pussy tastes amazing… Imagine you’re sucking your real Oppa’s cock…"
"Uuup!!"
Eunbi’s finger swirls deep inside Dain’s pussy. Wet squelching sounds fill the air. The hole keeps clenching and unclenching, producing more juice. Unable to take it, Dain suddenly spits out the cock she had swallowed to the root.
"Haa…! Haa…! Unnie…!"
"You’re sucking so well, why spit it out? Suck it again…"
"Aaaah…! Uheung…!"
Blown away by the taste of his little sister’s mouth-pussy, Seongjun grabs his own shaft, aims the glistening cockhead at her shiny lips, lifts his hips a little, and thrusts in.
"Uup!!"
"Suck it with those little smacking sounds. You’re doing great."
Eunbi gives a small nod of her head. Seongjun understands instantly. He grabs his little sister’s head with both hands and drives his hips up hard.
Thud!!!!
His vein-ridged cock punches straight through Dain’s throat in one go. Her eyes fly wide at the sudden assault. She thrashes to get free, but it’s no use. Oppa has her head locked tight. He drops his hips and the cock slides back out.
"Oppa…! Oppa…! Uweeeek…!"
"Hey, pull out."
"Yeah, she’s really struggling."
He pulls his cock free of her throat. The spit-slick shaft springs out like a released coil. Dain’s cheeks are flushed red. She glares at her big brother with a look of pure resentment.
"What the hell was that, you bastard!"
"That’s what you get for teasing… If you’re gonna suck cock, suck it hard until the water’s gone… huh?"
A rough wet sound rings out. Eunbi’s finger has just speared through her pussy. She appears right when the mood turns sour and saves the day—this fucking bitch is a treasure. She’s giving it everything she’s got. I ought to repay her.
"Kkyahaang!!"
"Finish what you were saying earlier… Tell me. You’ve never imagined doing it with your real Oppa…?"
"Kkeuheung…! Aaaang…!"
Instinctively the little sister grabs Seongjun’s cock and starts pumping it like crazy. Both siblings’ bodies twist and thrash on their own. Eunbi works Dain’s pussy while Dain frantically strokes her big brother’s dick.
"You’ve never done it… huh…?"
"I have, Unnie!! Stop!! Ahang!! Ung-ung-ung!!"
Eunbi’s hand freezes, finger still buried deep inside the pussy. Juice leaks out in thick streams, runs down the bed, and drips onto the floor. Dain pushes her ass back, asking for more, swaying it side to side.
"Oh my… Really…? You’ve imagined fucking your real Oppa…?"
Head still hanging, the little sister gives a tiny nod. Eunbi’s hand slides out of her pussy; sticky fluid stretches in a long string from her fingers—pussy juice. She creeps toward Seongjun, who’s sprawled out on his back.
"Open your mouth, you bastard."
I open wide just like she wants. She shoves the fingers coated in little-sister pussy juice into my mouth. I suck them clean.
"You said you wanted to do it with your little sister too, right?"
"Yeah."
"And Roa just said she’s imagined it… So we can just do it the way we always do."
"Heh… Should we? I mean, I want to…"
"What do you think?"
A horny big brother and an incest-obsessed Eunbi both stare at Dain at the same time. She still can’t lift her head, looking utterly mortified. Fair enough—she just came out and admitted she’d fantasized about fucking her Oppa right in front of him. And she’s completely naked.
"Haa…! Haa…!"
"I’m asking you, you fucking bitch… huh?"
"Unnie…"
She finally raises her head. Fat tears well in her eyes. Eunbi quickly wipes them away, then reaches behind her and pushes a finger back into her pussy, working it as freely as if it were her own. Dain doesn’t refuse. She’s enjoying Eunbi’s fingers.
"Uueung…! Ahaang…! Kkeuheung…! Aaa…! It feels good, Unnie…"
"I’m asking you what you think… Imagine you’re doing it with your real Oppa… huh? Doesn’t that turn you on like crazy?"
"Ahang!! Kkeuhang!! I’m losing my mind, Unnie… Aaaang…! I want to do it with Oppa!!"
"Your real Oppa?"
"Haa…! Haa…! Yes, my real Oppa…"
Half-lidded eyes meet Seongjun’s. She grabs his cock tight, parts her glistening lips wide, and swallows him to the root in one go. She lifts her head and then slams it back down, over and over, staring straight into her big brother’s eyes while she sucks his cock.
"Uuugh…!"
"That’s right, Roa… You’re sucking your real Oppa’s cock… huh?"
"Aaa…! Little-sister mouth-pussy tastes fucking incredible…! I’m gonna cum…!"
"You fucking bastard… You can’t cum yet… huh? Hold it."
"Aeuuk…!"
I pour every ounce of will into holding back the orgasm. My thighs and ass go rigid, locking up. My cock swells like it’s about to burst—right inside my little sister’s throat.
"Pull off, Roa… I’m really gonna cum…! Uheuk…!"
"Cum for me… Oppa…"
Out of nowhere the little sister spits the cock free. Our eyes lock. We trade hot breath.
"I want to drink Oppa’s cum…"
"Huh?"
"It looks exactly like my real Oppa’s cock… Haa… Haa…"
"Don’t tell me you…?"
"Yeah… It’s so thick and hard… Exactly like my real Oppa’s cock… Cum for me…"
She seizes the cock with both hands, stretches her lips wide enough to tear, and slams her head down hard.
