Service Training (4)
His tongue burrows deep and spins clockwise, slow and deliberate.
Pussy juice drips down it in thick strands with every turn, soaking his entire face.
Sweet.
He gulps it down greedily.
One finger rises straight. He jabs it against her asshole, poking insistently.
Eunbi’s hips sway side to side.
“Uhhng…! Oppaaa…! Don’t put it there…”
“Yeah, it was winking so hard I got curious.”
“Haa…! Haa…! Your cock’s so fucking hard… Oppa, you okay?”
“Yeah—my little sister’s sucking my dick right now… Blood’s rushing so hard I feel like I’m gonna die…! Aaugh…!”
Eunbi locks eyes with Dain head-on. For show, she swallows his cock all the way to the root. The outline of the head stands out clearly against the back of her throat. Soft tongue and the silky flesh of her gullet chew on Seongjun’s cock with slow, deliberate pressure.
She pulls off. Licks the head with her tongue.
“How do you suck?”
“I don’t know, Unnie… I’ve never gone that far…”
“Hehe… Watch carefully. You’ll be sucking Oppa’s cock soon enough too.”
Eunbi deliberately lets her eyes go half-lidded. Soft moans spill out as she sticks her tongue out long again, cleverly lapping at his balls and the underside of the shaft.
Dain’s breathing grows ragged. Without realizing it she clutches her own chest.
“Oppa, Roa’s getting turned on too… She’s touching her tits…”
“Uuugh…! Fuck, she really is… Getting wet watching us?”
“Yeah, looks like it… Hehe… And your cock’s fully hard at this point… You’re struggling too, so shall we start the main event?”
Eunbi rises and spins to face Seongjun. Their eyes meet. She doesn’t look away—stares straight through him. Slowly she sinks down. At the same time her hand wraps around his cock and presses it flat against his stomach. The split of her pussy lips kisses the thick, veined shaft.
She sits all the way down.
Soft moans leak from both of them.
“Haaeut…!”
“Uuung…!”
She draws her hips back, then drives them forward hard. The throbbing cock parts Eunbi’s pussy lips and glides past. Pre-cum and pussy juice mix. Fresh wetness blooms. The wet slap of flesh on flesh echoes—the sound of cock and cunt making music together.
Seongjun’s hands climb to her chest. He grabs a tit in each palm and kneads.
“Haa… haa… Cock’s gonna explode…”
“Uhhng…! Same here, Seongjun Oppa…”
“Uut…! Rub it gentler… If you go that hard… Ugh!!”
Seongjun’s thighs lock rigid. The cockhead that had been sliding along her pussy lips slips just inside the hole. She lifts her hips in a flash, still gripping the shaft, and stands it upright toward the ceiling. Peering between her legs, Eunbi guides the cock this way and that until she seats the head against her entrance.
“Ahaang…! Oppa, it’s touching… my pussy…”
“Krruut…! Fuck, Dain… Oppa’s cock is gonna blow if you keep this up… Uuugh…!”
“Haa…! Haa…! Oppa…”
“Yeah, Dain…”
“Like that time… shall we…?”
All motion freezes. Part of the cockhead sinks just inside Eunbi’s pussy. Her ass clenches tight, squeezing the barely-inserted head with her plush inner walls.
“Roa’s watching… Teaching her this isn’t good…”
“Then let’s just ask her… Haa… What do you think…?”
Dain’s throat bobs. She has nothing to say. She only stares, unblinking. One hand has slipped inside her pink dress, kneading her breast. The other rests in a place easy to misread—between her smooth thighs. A little farther and it would touch her pussy.
“Unnie…”
“Mm, speak…”
“When I first came in for training… they taught us we’re not allowed to have sex… Haa… haa…”
“That’s right, not wrong… but if the therapist gets horny, it’s fine to put it in…”
“What…?”
“Unnie’s about to lose her mind right now… Oppa’s cock looks so fucking delicious… Haa…”
“……”
“You get horny sometimes too, right? Clients try to shove it in, all that…”
“Yes… every time it’s awkward… The soundproofing’s terrible here…”
“Hehe… The manager and the boss both know… They just look the other way… Know what my nickname is…?”
Dain shakes her head, pretending not to know. But she already does.
Automatic Door.
Eunbi’s nickname. Even though sex is banned, she spreads her legs wide like a crazy bitch in heat. She fucks all day long. Dain has heard it often enough—the wet slap of flesh on flesh. Unmistakably the sound of people fucking.
“I’ll show you from now on, Dain… This is training too… If there’s someone you want to give it to… just do it like Unnie…”
“Haa… haa…”
“Climb on and spear yourself like this… and nobody says a word… Who’s gonna bitch when I say I’m horny…”
“Are you… really going to…?”
“Yeah… this Oppa’s cock… tastes so fucking good… Haa… My pussy’s itching so bad I can’t hold back anymore… Uuung…!”
Slowly she sinks her hips. The veined cock drives into Eunbi’s pussy. Her blood-related little sister watches, breath held. Her blood-related older brother’s throbbing cock vanishes between the ass cheeks. Groin meets groin. Only the two balls dangle free beneath Eunbi’s ass.
They are fucking.
“Ahang!! Uuung…! Kkeung!! Aaaang…! Oppaaa…!”
“Uhhuk…! Dain…! Fuck…! It’s in…! Oppa put his cock in his little sister’s pussy!!”
Her hips lift high. Seongjun’s cock, buried to the root, pops free. A long string of pussy juice stretches between them, connecting cock and cunt. Eunbi gropes for the shaft again, then shouts toward Dain.
“Haa…! Haa…! Roa… can you put it in for me…?”
“Me…?”
“Yeah… Unnie’s… struggling right now… My hands won’t reach…”
A blatant lie. Half-lidded eyes lock on Dain as she coaxes her to grab her own brother’s cock. She already knows the girl is worked up. She wants her to shove it back into Unnie’s pussy.
“Unnie… your face looks weird… Does it feel that good…?”
Dain slowly rises. First time she has moved since sitting in the chair after entering the room. Her dress shifts, baring the delicate line of her shoulders. Power surges into her brother’s cock. Between those smooth, long legs her panties flash into view. Her wariness has melted.
The little sister’s hand reaches for her older brother’s groin. It trembles faintly.
It touches.
“Haa…! Haa…!”
“Uuugh…! Fuck…!”
“Good girl. Grip it tight and push it into Unnie’s pussy…”
Strength gathers in Dain’s hand. Her palm curls into a circle. Her blood-related older brother’s cock settles into her blood-related little sister’s grip. She squeezes hard. Aims it straight at Eunbi’s cunt.
“The cock… is so hot, Unnie…”
“Uung… That’s because he’s thinking about fucking his little sister’s pussy… Don’t hesitate—shove it in for me, will you…?”
“Yes… if that’s what you want, I’ll put it in… Because Unnie asked…”
She pushes it home in one long stroke. The blood-related little sister spears her older brother’s cock into another woman’s pussy. It sinks to the root. Mind-breaking excitement flashes through Seongjun’s skull. His hips jerk upward.
“Ahaang!! Oppa!!”
“Uhhuk…! Dain…! Uuuugh…! Kkeuk!!”
Dain’s hand is still trapped between the joined cock and cunt. She does not pull it free. She simply watches. Swallows hard. The mixed juices of Eunbi’s pussy and Seongjun’s cock soak her hand completely.
“Move, Oppa…”
“Haa…! Haa…! Got it… You’re watching right now, yeah…?”
“Yes… I want to watch Oppa and Unnie… fuck…”
“Uhhuk…! Fuck, Dain…! Dainaaat!!”
Seongjun drives his hips up hard. Rough wet friction fills the room. Unbelievable filth spills from his little sister’s mouth—she just said she wants to watch her Oppa fuck. The last thread of reason snaps.
The hand that had been kneading Eunbi’s tits reaches back. He grabs each of her ass cheeks and spreads them wide. Inner pussy flesh peeks out. The sight of those plush walls chewing on his veined cock reflects in his little sister’s eyes.
Thwack! Thwack! Thwack! Thwack! Thwack!
With Dain’s hand still sandwiched between them he slams his cock deep into the pussy again and again. Orgasm surges like a tidal wave. He does not stop. He has decided to show her—the sight of her own Oppa dumping his load.
“Uuugh…! Shit!! This pussy’s so fucking tight and chewy!! Dain!! Oppa’s gonna cum!! You fucking bitch!!”
“Ahaang!! Yeahyeahyeah!! So hard, Oppa’s cock…! Cockkkit!! Pound your little sister’s pussy hard!! Oppaaaat!!”
“Kkeuaaat!! You fucking bitch!! Cumming… I’m cumming!! Dumping my load in my blood little sister’s pussy!!”
“Cum, Oppa!! Cum in my pussy!! I want Oppa’s cum!! Fuck me!! Kyaaaaak!!”
He drops his hips all the way. Power explodes into Dain’s hand still wrapped around the shaft. She milks her older brother’s cock. In that instant both balls draw up tight and something thick surges the length of the shaft.
With every ounce of strength he lifts his hips.
THWACK!!!!!
A tearing wet slap rings out. Seongjun’s swollen cockhead plows past the ridged inner walls. A slick, sliding sensation, then it is sucked somewhere deep—Eunbi’s womb. Something unstoppable tries to burst from the slit of his cock. Thighs and ass lock rigid. Superconducting cum that answers to no resistance ignores gravity and erupts at light speed.
“Uuuaaaat!! Dain!!”
“Ahahaaang!! Seongjun Oppa!!”
Both heads snap backward. Mouths gape wide, drooling foamy spit. Their whole bodies shudder like aspen leaves. Eyes slowly roll white. From the seam where cock and cunt meet, a mixture of cum and pussy juice spurts out hard. Some of it spatters across Dain’s watching face.
She does not flinch. She stares unblinking. Tongue slips out just a little. She licks her own brother’s cum from her lips so carefully no one notices.
“Aaaah…! Aaaah…! Aaaaaat…!!”
“Uhhng…! Kkeung…! Ahaaaang…!!”
Dain still grips her older brother’s cock. She squeezes rhythmically, forcing the buried shaft even deeper, wringing every last drop of remaining cum into Eunbi’s pussy without leaving a single bead behind.
“Haa…! Haa…! Uuugh…! Stop touching it, Roa…!”
“You like it… Oppa…”
“Aheut…! No…! It’s gonna come out again…! Fuck…! Fuckkkk…!”
Seongjun’s hips twist on their own. His cock answers his little sister’s touch. Both balls draw up tight once more. Through the wide-open slit a thin white liquid blasts out at light speed. Cum pours like a waterfall from the joined seam of cock and cunt.
“Unnie… does it feel good…?”
“Haa…! Haa…! Yeah, I thought my pussy was going to burst… Thanks to you…”
“It’s still flowing out… I think I need to wash my hands…”
“Yeah… go wash up in the bathroom… You’ll need to try it yourself next…”
Dain pulls her hand free and crawls toward the bathroom, eyes fixed on the cum-soaked palm. Not a trace of shame remains. Eunbi and Seongjun watch, stunned. Something inside her has clearly shifted.
Their eyes meet. A faint smile curves both mouths.
Now it is Dain’s turn.
The blood-related little sister climbs onto her blood-related older brother’s stomach.
