So-jin the Fuck-Toy Makes Her Entrance
So-hee came home after her smoke break, climbed the stairs, and began unpacking her things. Then evening fell.
"Hmmm... that bitch I ran into while I was having my cigarette earlier today... where have I seen her before..."
She turned it over in her mind. It was a face far too familiar to just write off as some stranger's and walk past.
"...Ah...!"
And then it came to her. The lightbulb in her head flicked on at last.
"...Pfffft, hahaha, that's it, haha — fuck — I know exactly who she is."
Back when her husband was still in Korea, she had once dragged her suitcase all the way to Juhwan's university. She'd spotted him on campus that day — and he had been talking with a woman with long, straight, honey-yellow hair.
Even the words she'd tossed at him afterward came back to her. "Oh my, got yourself a girlfriend? Hahaha."
"That little shit. I told him I'd kill him if he hooked up with another bitch while I was gone..."
"Couldn't even last a single day... he's rolling around with her? And he brought her into his own home, no less??"
Her fist clenched and began to tremble with fury. The smile drained from So-hee's face, leaving only an icy expression behind.
"...Hold on, now... should I just chop that bastard's dick clean off?"
"That cock is mine to touch — mine alone... and while I was away, that fucking slut got a taste of it...?"
"This makes me so goddamn sick..."
She picked up her phone and opened her messages, meaning to leave him a text. The contact name saved for Juhwan on So-hee's phone was:
[The Beggar Downstairs ♥]
".......This... this cock-sucking little bastard... is trying to piss me off...???"
Hands shaking, she jabbed at the message button — and at that very moment,
Beep-beep-beep-beep, beeeep~
The doorlock of So-hee's apartment chimed and swung open. Geon-young was home from work.
"Honey~ I'm home~ How was the trip to your parents', sweetheart?"
As Geon-young stepped into the living room, the first thing he saw was So-hee sitting on the sofa, her expression cold as stone.
"Huh? Honey... what's wrong? Did something bad happen?"
At that, So-hee brightened as if nothing had ever been the matter, launching straight into her performance.
"Oh my, honey ♡ What took you so long, hehe? Do you have any idea how long I've been waiting, hehe?"
"Ah... oh, right! You're not upset about anything, are you?"
"Pfft, upset about what! Haha. Go wash up! I'll get dinner ready, hehe."
So-hee headed to the kitchen and started on Geon-young's dinner. She sliced the tofu and scallions, stir-fried the pork with kimchi, splashed in some water, and let it bubble away until a delicious kimchi stew came together.
Geon-young finished washing up, changed into his pajamas, and came out to find So-hee waiting.
"Wow... honey! How did you know I was craving kimchi stew tonight...!"
"Oh, come on, obviously, heh. We share a telepathic connection, don't we? I just knew you'd want this, so I made it ♡"
"Thank you... hahaha. I'm always grateful for you, sweetheart."
Mwah.
Geon-young planted a kiss on So-hee's cheek.
This was the kind of man Geon-young was: completely oblivious to how depraved his wife's behavior was whenever he wasn't home — a man who knew nothing but his job and his wife. A pitiful man.
"Aigoo ♡ Ah, that's nice... hehe. Honey, the stew's going to get cold! Let's eat, hehe."
The two sat down at the table and ate dinner while gazing at one another. Somewhere in the middle of it, Geon-young asked cautiously.
"So... honey, hehe. How did things go at your parents' place? Did you sort everything out?"
At those words, So-hee let out a long sigh.
"Ugh... don't even get me started. You know full well what a nightmare So-jin's personality is, honey."
"She just keeps roaming the streets doing God knows what... Our parents scraped together everything they could to get her into some junior college nearby, thinking maybe she'd finally pull her head out of her ass and study..."
"...But she stopped attending even that, and get this — the school actually mailed an academic warning notice to the house. Can you believe it??"
"An academic warning...? Oh, dear... What are we going to do with her?"
"Ugh, who knows... She's twenty-three years old. How long does she plan to live like this?"
"You were gentle with her, right? You didn't just start chewing her out the second you saw her?"
"...Huh?? Oh — no, no! Hahaha. I... I tried to talk things through, but... she wouldn't listen..."
"...Still, I'm worried about her..."
Even in the middle of this conversation with Geon-young, thoughts of Juhwan were slowly worming their way up from some corner of So-hee's mind. The mere image of Ji-hee rolling around in Juhwan's apartment made her blood boil hotter and hotter.
Truthfully, from So-hee's standpoint, all that had actually happened was running into Ji-hee outside the building while she was having her smoke. It would be difficult to say with any certainty that Juhwan and Ji-hee had actually had sex in that apartment.
But none of that mattered to So-hee. She was absolutely certain the two of them had fucked. Period.
And with that certainty came another thought — the image of Juhwan's cock buried deep, stitching itself into another woman's pussy — and even as rage surged through her, So-hee's pussy gave a faint, involuntary twitch.
Geon-young caught it instantly.
"Honey... are you feeling okay? You seem a little off tonight?"
"Oh — no, I'm fine, hehe."
"Fine, huh? You do seem a bit different from usual..."
Geon-young reached out and pressed his palm against her forehead.
"Doesn't feel like a fever..."
"...Mmm..."
And this was when So-hee's acting talent truly earned its keep.
"...Well... I am a little uncomfortable..."
"Hm? Uncomfortable? Where?"
Geon-young asked where it hurt, then picked up his glass and took a sip of water. So-hee spread her legs on the spot.
"Honey... it's been so long since we've done it, hasn't it...? ♡"
"PFFT!!!"
Geon-young sprayed his mouthful of water across the table, visibly flustered.
".......So are you going to keep eating your dinner...???? Or..."
So-hee undid the buttons of her pajama top one by one, pulling out the enormous breasts beneath.
"...Would you rather eat something else? ♡"

Gulp... Geon-young swallowed hard, his Adam's apple bobbing up and down.
".....Honey..... You're as sexy as ever...?"
So-hee dragged her chair over beside Geon-young and sat down, stroking his thigh.
"Honey... I'm going this far for you... and you're just going to leave me hanging like this? T_T?"
She took his hand and pressed it onto her bare chest.
"Mmmmh?? Honey~♡ Are you going to eat the kimchi stew~? T_T Or... are you going to eat me~?"
".....Is that even a question...?"
Heave-ho!!
"Kyaa! Honey, you're insane! Hahaha!"
Geon-young shot up from his seat, scooped So-hee up into his arms, and strode calmly toward the bedroom.
The moment they reached it, he laid her down on the bed with the tenderest of care. She wrapped both arms around his neck, and the two of them kissed.
"Mmmm... shluuurp ♡ I can taste the kimchi stew... hehe. I made it myself, but it really is good, isn't it ♡"
"Hahaha... should I go brush my teeth first?"
Just as Geon-young rose to go brush his teeth, So-hee grabbed him by the collar and yanked him back down.
"Honey ♡ Where do you think you're going? There's no time for brushing teeth, hehe."
She kissed him again — and this time it was an all-out assault of a kiss.
"Shluuuurp ♡ Hah... haha. Forget the kimchi stew — your tongue tastes way better, baby ♡"
"...Me too, honey... How long has it even been for us...?"
She couldn't exactly argue with that.
Geon-young's overseas business trips had always been frequent, and their married life had naturally withered along the way. To be sure, So-hee had been working off her lust with other men during all those absences — but Geon-young had nothing in the world but So-hee. From where he stood, this was sex after a very, very long drought.
Geon-young and So-hee began stripping off their own clothes. His muscular physique and her heavy, cow-like udders were laid bare without ceremony.
Geon-young went for her breasts first, lips closing around one, and So-hee began to let out sweet, melting moans.
"Nnnnngh ♡ Haaang...♡ There... it's been so long since you sucked on them, I'm going crazy...♡"
(So long, my ass... haha. Juhwan sucked on these just a few days ago, that son of a bitch. I really am a pretty good actress, huh?)
Meanwhile, her hand found Geon-young's erect cock and began stroking it. Geon-young kept his body in shape with regular exercise, so his cock was by no means small.
Compared to Juhwan's, however, it belonged squarely to the ordinary category.
(Fuck... now that Juhwan's cock has broken me in... my husband's just doesn't cut it anymore...)
When the foreplay wound down, So-hee pushed Geon-young onto his back on the bed.
"Honey... hehe. Since it's been so long... let me ride you first tonight? ♡"
She pressed his cock against the entrance of her pussy and began to sink down, slowly.
"Ahh... nnngh, aaaaah-hahaaahh!"
It was an act.
Having been trained to the limit by Juhwan's goddamn monster of a cock, So-hee found Geon-young's less than satisfying.
But this was her husband — so she faked pleasure as convincingly as she could.
"Aaaang... it's been ages since I got to taste your cock, baby...♡ My husband's cock is the best...!"
"Ha... ha... You're the best too... you're the best, So-hee...! I love you...!"
"Mmmmh? Hehe, this feels so good... honey... I love you too ♡"
And then.
Beep-beep-beep-beep-beep, beeeep~
The front door's doorlock suddenly chimed — and opened.

"....Huh?!"
"WHAT THE HELL?!"
No one was supposed to be coming. So-hee had never once given out her apartment's passcode — not even to Juhwan, who lived downstairs.
So-hee and Geon-young scrambled apart, clawing for their clothes in a panic — but the footsteps of whoever had punched in the code were drawing closer and closer.
"Unnie, I'm back."
"..?!?!? KIM SO-JIN?!?!?!"
"..What?? My sister-in-law?!?!"
It was So-jin, So-hee's younger sister.

Black hair in short pigtails. Her cat-like eyes were sharp just like So-hee's, and the two resembled each other just closely enough that anyone could tell at a glance they were sisters.
"Hey! What the hell is wrong with you?! You show up without so much as a heads-up?! And you think this is your house?! Why didn't you ring the bell?! What if someone just barges in like this, huh?!"
"Heee~ hold on a sec."
So-jin took in the scene before her. The moment she'd stepped inside, the pair had scurried off to hide, hastily throwing their clothes back on.
"Heh, hahaha. What were you two busy doing~~??"
"Wait, hold on, hahaha. Don't hide, let me see. Ahh~ you two were fucking, weren't you~?"
"F...fucking...?? Hey, you little—!! Are you kidding me right now?!"
While So-hee and So-jin bickered, Geon-young — who had barely managed to get himself dressed — reappeared.
"S...So-jin... hehe. It's... it's been a while..."
"..!!"
The moment So-jin laid eyes on him, her eyes went wide.
"Oppaaaa~~!~!!"
She darted straight for Geon-young and buried herself in his arms.
"Oppa oppa oppa oppa oppa~~ it's been forever~♡"
"Ha... hahaha... S...So-jin....."
"Hey, Kim So-jin. Get off him."
So-jin stuck her tongue out at her sister.
"Nooo thanks~ hahahaha. A guy this handsome and sweet — why should you get to hog him all to yourself, unnie??"
"Oh, and by the way... you two were actually having sex? So you got caught mid-fuck by little old me? Pfft, hahahahahaha."
A moment later, something shifted in So-jin's eyes, and she turned her gaze on Geon-young.
"Oppa~ hehehe. Forget a nasty-tempered bitch like my unnie... how about me instead? ♡"
"Haah... S...So-jin... what on earth are you saying..."
SMACK!
So-hee slapped the back of So-jin's head, hard.
"OW, FUCK! UNNIE!!!!!"
"Lower your voice! Do you think this is your house?! Aren't you embarrassed to do this in front of your oppa?!"
*A short while later, in the living room of So-hee's apartment*
So-hee had peeled some fruit and arranged it on the coffee table, and So-jin sat sprawled on the sofa like a child, picking at it. Geon-young was glued to her side.
To put it precisely: So-jin was gripping Geon-young tightly and refusing to let go, so that he had nowhere to escape.
"Oppa~ hehe ♡ You smell so good, oppa ♡"
"......"

So-jin had shown up at her sister's place without a bra on. Her nipples poked visibly through the white tank top she was wearing, and while the sight made Geon-young distinctly uncomfortable, So-jin knew exactly what she was doing — deliberately rubbing her chest against his arm, teasing him without a shred of shame.
".....So, let me get this straight..."
"Mom and Dad kept nagging you about not going to school..."
"You wouldn't listen to a damn word they said, so they tried to get you a job at some factory..."
"...And you hated that so much that you packed your bags and ran away from home without telling them a thing? And the destination of this grand runaway was our apartment?"
"Hey, Kim So-jin... are you a child? You're a full-grown adult — what is wrong with you?"
But So-jin wasn't listening to a word of it. She just hung off Geon-young's arm, rubbing her chest against it while she ate her fruit.
"Uh... So-jin... come on, stop that... And from what I hear, you got an academic warning sent home, of all things..."
"Wouldn't now be a good time to... actually give school an honest try?"
So-jin stared at him blankly for a long moment.
"School???? Hmm........... Nah!"
"YOU— YOU LITTLE!!!"
So-hee looked ready to brain her, but Geon-young held her back.
"Haah... Hey. Do you have any idea how much your mom and dad suffered trying to get you into that junior college?"
"And your oppa? My husband chipped in for your tuition too, you know!"
"Um... So-jin... setting the tuition aside... for your own future's sake..."
But So-jin remained as unserious as ever.
"Hmm~~ hahaha. Let me go on a date with just me and oppa, and I'll consider it!"
".....You insane bitch..."
"Honey... enough with the cursing..."
Having devoured the entire plate of fruit single-handedly, So-jin stretched with a satisfied groan.
"Yaaawn~~ I'm full, and now I'm sleepy..... I'll just take a shower and go straight to bed, 'kay? The bus ride really wore me out today..."
She sprang up on her own and headed for the bathroom — then stopped dead, turned around, and looked back.
"Unnie! I can sleep with oppa tonight, right?"
"You insane little—!"
"Why noooot~ hehehe. I wanna cuddle up all night with my oppa, that's why, sob sob."
"Our oppa would obviously prefer a young, springy girl like me over a dried-up old fox like you... wouldn't he~?"
"CHK!!... Ahem.........."
Humming a little tune, So-jin slipped into the bathroom and vanished.
"Haah..... that girl, I swear......."
"Hold on... how long is she planning to stay here, exactly...?"
"I'm sorry, honey... I'll kick her out as fast as I can..."
"Honey... don't just throw her out blindly... Let's try talking her around together, gently..."
"Haah... honey, that's exactly your problem. Sometimes you have to be firm when firmness is called for. Be nice to that girl, and she'll never listen to a word you say..."
*At that very moment, in the bathroom*
So-jin was showering, every stitch of clothing discarded.
"Mm~ mm-mm~~ mm~"
Humming to herself as comfortably as if this were her own home, she showered — then began touching herself, one hand on her breast, the other rubbing her pussy.
"Haaang... oppa...♡ I'm washing myself in the place where oppa washes every day ♡"
"Oppa... I want you so bad ♡♡ Hehe... Tonight I'll kick unnie out and fuck you myself ♡"
"My pussy's way tighter and way better than some hag's old cunt like unnie's ♡♡♡ Oppa needs to know that too, no matter what ♡"
"Haah, fuck, hahahahaha. If oppa hadn't married my unnie yet... I'd have his cock in my mouth and I'd never, ever let go... What a waste... haha."

So-jin, getting herself off all alone...
Meanwhile, outside the bathroom, all that could be heard were the weary sighs of So-hee and Geon-young.
