Service Training (7)
Seongjun spreads his legs as wide as they will go. Shame has long since been flung far away. His little sister stares straight at her own brother’s asshole—his cock and balls thrown in as a free bonus.
“Go on, Roa...”
“Haa... haa... It’s so clean...”
“Doesn’t smell at all, right? This Oppa takes really good care of his ass... Trust Unnie and give it a lick first.”
“Okay, Unnie... Just lick it with my tongue...?”
“Yeah, you saw earlier... Just do exactly what Unnie did.”
Dain slowly pushes her head forward, closing in on her brother’s asshole. She sticks her tongue out a little. This is her first time rimming—and the partner is her own flesh-and-blood brother. Someone else is watching. Her brother’s hole keeps winking open and shut. It’s fascinating. From a distance where she can almost touch, she blows a hot breath against it.
“Uuugh!!”
Seongjun’s ass cheeks shake side to side. His waist bounces up then drops limp. The cock that gravity had left hanging now stands tall and proud toward the ceiling as blood surges into it. Pre-cum dribbles down in thick strands. It feels incredible. He just felt his little sister’s breath on his asshole. He wants her to shove that tongue in already. Without thinking he stretches both arms back, lays his hands over Eunbi’s, and forces his cheeks even wider.
“Oh my... Look at this fucking bastard... Spreading himself open because he wants to get rimmed... Huh?”
“Haa... haa...”
“Roa, the cunt bastard’s struggling... Hurry up... Stroke his cock too...”
All at once Dain’s hand slides between his legs and clamps hard around the veiny shaft. Seongjun’s head snaps up and a pleasure-soaked cry rips out of him.
“Ugh...! Ahaah...!”
“Feels good? You fucking bastard.”
“Uh, my cock... My cock’s gonna explode...!”
“We haven’t even started yet... Roa, hurry up and rim him already?”
Something rockets toward her brother’s winking hole at blinding speed—her little sister’s fully extended pink tongue, cutting the air.
Thud!!!!!
It collides. A raw friction sound echoes as Dain’s head buries itself between her brother’s cheeks. In one brutal thrust she drives her tongue in to the root. Seongjun’s whole body convulses like it has been struck by lightning.
“Ugh!! Uuugh...! Guhah...!”
“Fucking bastard, even your moans come out so fucking delicious... Huh?”
Eunbi suddenly seizes a fistful of Seongjun’s hair and shakes his head wildly side to side. She gathers spit and spits it square onto his face—perfect hit. He has already lost his mind to the tongue buried deep in his asshole and never even registers the spit. His mouth hangs open, foamy drool spilling out as his entire body starts to tremble. The handjob on his cock only gets faster.
“Haa...! Haa...! Slurp...”
“How is it? Does the cunt bastard’s ass taste good?”
“Yeah, it’s edible... His reactions are so good I want to do more...”
She greedily sucks and licks her brother’s hole, spinning the tongue she has shoved deep in slow circles, rummaging the fuck out of him. Every time she does, his waist jerks up and then collapses. His balls draw up tight. The urge to cum crashes over him like a wave. His cock dances in his little sister’s soft palm as she squeezes, opens, and presses down hard. It’s fun. The little sister bitch keeps smiling brightly while she rims him.
“Haa...! Haa...! Fuck, he’s already about to cum... Huh? You son of a bitch!”
Dain throws her head back and spits the dual curses, yet her brother only gets more excited. He spreads his ass even wider—begging to be licked. The corners of her mouth lift as she stands two fingers straight up and drives them into his twitching hole.
Thud!!!!!
They sink to the root in one go. A scream-laced moan bursts from Seongjun’s mouth. He thrashes trying to push the invading fingers out, but it is useless; he only ends up shoving his ass farther back onto them.
“Hehe... Crazy bastard, so fucking perverted...”
“Aaaaaah!! Fuck!! It feels too good!!”
“This bastard’s about to cum again... Huh? No good... Gotta punish him.”
She wrings his cock like a wet rag. Indescribable pain shatters through Seongjun’s body. His head snaps back; fat tears spill from bloodshot eyes and mix with the foamy spit already running down his chin.
“Kuuut!! Uut!! Aaaa!!”
“You can’t play with the cock, Roa...”
“Hehe... Unnie, this bastard’s reactions are too fun...”
The crazy bitch keeps smiling sweetly while she freely fondles her brother’s cock. Even Eunbi is startled—Dain is the complete opposite of the girl from moments ago. The fingers buried between his cheeks pull free, dragging the pink inner flesh out with them.
“Wow... So this is possible too...”
“Unnie try putting them in... When I finger him he completely loses it.”
“Nah, I’m good... There’s more important stuff left...”
“Huh?”
“The back side is enough for now... Shall we start the main game soon?”
“Main game?”
“Aigoo... Why ask when you already know... Gotta take care of the front of this fucking bastard too... Drain him properly... Roa.”
“Ah... I forgot, Unnie...”
Dain’s expression flips in an instant. The thought of climbing onto her brother’s stomach floods her head. She flings the cock she has been holding aside like trash. Only then does the full weight of what she has done hit her. Her brother’s gaping, thoroughly used asshole is on full display, clear fluid still dripping from it, the rim flushed bright red.
“Hey, how long are you gonna stay like that? Lie down properly, you fuck.”
“Haa...! Haa...! You keep cussing, you fucking bitches...”
“Hihi... Acting up even though you love it... Huh? Just do as you’re told—no more words!”
Eunbi grabs Seongjun’s hair again and shakes him roughly. Swallowing the rage boiling up inside him, he corrects his posture, flips over, and sprawls on the bed in a full X. He spreads both legs wide and flexes his cock so it nods. The veins stand out so hard they look ready to burst. He aims the head straight at his little sister.
“Wow... His cock got even bigger... Isn’t this thing gonna explode?”
“Haa...! Haa...! You two made me this horny... Uuugh...! Fuck, it really feels like it’ll explode.”
“Hehe... Looks like you got super horny because of us... Should make you comfortable? Hurry and drain that water.”
“Uung... Unnie...”
“Why the sudden change? You looked so excited a second ago... Now you’re all serious.”
“Ah, no... Because I’m about to do the front... I’m embarrassed... A little.”
“Aigoo... You too—after you already rimmed him... Just relax and suck the cock... Huh?”
“Uhung...!”
Eunbi’s hand dives between Dain’s legs, finds her pussy, and pushes a finger straight in. A wet squelch fills the air. The fragile string of reason Dain had barely managed to cut snaps right back into place—then Eunbi helps her break it for good. Both of Dain’s legs start trembling; her heels lift off the floor.
“Aung...! Unnie... Stop...”
“Feels good? Unnie fingering your pussy...”
“Uung... Good, right there... Ahaang...!”
“Hehe... Here? The round part?”
She presses the swollen spot hidden deep inside. Ever since Dain squirted, Eunbi has known exactly where her erogenous zone lives. Press that round, puffy place and the girl loses control of her body. Eunbi pulls the finger free and gently massages the bumpy inner walls. Dain’s ass clenches tight then blooms soft again. She moans without a shred of shame, the last thread of reason finally severed.
“Haa...! Haa...! Uuung...! Aaaang...!”
“That should be enough? Solve the rest with that bastard’s cock... Huh?”
“Haa...! Haa...! Unnie, what do you mean...”
“You saw Unnie do it earlier, right? Grab the cock and shove it into your pussy... When you’re so horny you can’t hold back.”
The crazy bitch is openly goading her into incest, telling the little sister to push her own brother’s cock into her cunt without the slightest hesitation. Dain still has no idea that Eunbi already knows everything. The finger plunges back in, spinning clockwise, then pulls free again, dragging pink pussy flesh out with it.
“Uuung!!”
“Hehe... Your pussy and that bastard’s cock... Seem like they’d match perfectly...”
“Haa...! Haa...! Really...?”
“Yeah. If you’re curious, try putting it in once... Unnie already showed you how...”
Dain’s throat bobs as she swallows. Worry hits her hard. She steals a glance at her brother’s cock; it twitches like a living thing. Her breathing turns shallow. She grabs the lube bottle and squeezes a long ribbon of gel onto Seongjun’s sprawled body, then starts rubbing it in with both hands.
“Uuum...!”
It feels like a dream. His little sister is completely naked, oiling her own brother’s body. Her pupils are half-lidded; she peers between his legs with a lewd little expression. Cute. He wants to devour her—wants that little sister pussy. He follows her hands as they slide lower, reaching his thighs, rubbing gently. Soft. Feels good. Then mad excitement spikes through his skull. Dain’s fingers dig into the crease of his crotch, working every fold, brushing his balls. His cock twitches hard. Her hands stop. She stares straight into her brother’s eyes. He does not look away.
“So fucking pretty... Huh?”
“......”
“I’m so horny I’m dying—hurry up and do something... Eunbi’s urging you too.”
“Where’s Oppa’s erogenous zone...?”
“Huh?”
“Here...?”
Seongjun’s waist jerks up and drops. Her fingertip has just grazed his erect nipple. She starts tickling it lightly.
“Uuugh...!”
“Like it...?”
“Uh, the skill’s pretty useful... Fuck, uhuut...!”
“Pervert bastard...”
His little sister catches his hand and guides it to her own chest. He grabs. Fondles. So fucking soft—slick with lube, slippery under his palm.
“Uum...! So fucking soft... Huh? Feels good to touch...”
“Haa... haa...”
“Come a little closer... Let me feel that ass too...”
Dain’s upper body slides across Seongjun’s stomach. She sticks her tongue out and flicks the nipple she has been teasing with her fingers. His hand snakes around her back and cups one pretty ass cheek, kneading it while he keeps playing with her soft breast. His body feels like it is floating. Sticky, filthy skinship with his own little sister.
“Hey, that position looks hard... It’s fine—climb up onto the bed... Let’s do this comfortably...”
“......”
“I want to feel your pussy... See how hard my cock is struggling?”
“Yeah...”
“That fucking bitch is watching, so don’t worry... I won’t make the first move...”
“Haa... haa...”
“Climb on. Onto my stomach...”
Their eyes lock. The rims of both pairs of pupils are flushed red. She flicks his nipple a few more times with her tongue, then slowly pushes herself up and climbs onto the bed. Looking down at him from above. He stretches both arms out, inviting her onto his stomach. Still breathing hard, she plants her feet on either side of his waist and lowers her ass. Contact. Crotch meets ass. She slips and collapses forward until belly presses to belly. His throbbing cock slides along the cleft of her ass. As if he has been waiting for exactly this, the brother bastard wraps both arms around her back and hugs her tight. Cock and pussy face each other with almost no space left between them. At last the two blood-related siblings press cock against pussy.
