Iseul's Fear
After entering the room, Iseul quietly closed the master bedroom door and approached me where I sat at the desk.
She pushed my arm off the armrest, perched herself there instead, and guided my hand around her waist before resting it on her thigh. I slipped my fingers beneath her slip and began stroking her thigh as usual, then slid higher.
“Not wearing anything underneath?”
Nothing. No panties where there should have been.
In the red and blue glow from the monitor, I could clearly see her bare skin through the thin slip.
I gave her smooth, freshly shaved mound a brief caress. When I touched the precious place that had once carried her child, Iseul smiled softly and kissed my cheek. I kissed her back and continued stroking and kneading her soft thighs.
While absentmindedly watching the Bitcoin chart rise and fall on the screen, I touched her most intimate spot and felt some of the stress from today’s wild price swings ease away. Annoyed that I wasn’t paying her enough attention, she grabbed my face and turned it toward her.
“Is that all? Of course I came here planning to sleep over tonight, so I didn’t bother with underwear. It’s just extra laundry. So? What happened?”
“What happened? Yeah… haa…”
At her words, the incident with Eunhye came rushing back. We’d avoided the worst outcome, so I supposed it could be called resolved, but facing each other at work would be difficult for a while. Building anything close to a normal relationship would take even longer. A difficult future lay ahead.
I needed to give Eunhye endless trust and make her believe in me. One slip on this thin ice and everything would shatter.
The thought of having to keep walking this tightrope made my future at the company feel suffocating already.
One year left until the Naeil Chaeum Gongje savings matured.
Touching Eunhye—had that been a mistake? But it had felt incredible. That kind of pleasure was something I’d never experienced before.
Aaagh. Why the hell did I ask her that question in the first place?! What was I thinking? Now everything’s even more awkward!
My blood had been rushing south, so of course I’d thought like a sex friend. The idea that Eunhye might actually be interested in me just because she helped me out once was pure narcissistic delusion.
Still… that blowjob she gave me at the end…? That definitely wasn’t okay, right?
No no no no. Anyway, what I had to do now was make sure Eunhye didn’t suffer any emotional damage. And I had to do it while suppressing my own lust.
That was reality.
While I mumbled and pulled my face out of Iseul’s arms, staring blankly at the chart again, she pressed me once more.
“It’s related to you staying out last night, isn’t it? Who was it? You reeked of sex.”
“How the hell… why are you smelling my clothes?”
“Because it’s suspicious! You always come straight home after work to check coins, but suddenly you stay out all night? And it wasn’t with Jeonghun either. If it had been him, you would’ve smelled like alcohol or secondhand smoke!”
“Wait, you’ve been smelling me all this time!?”
“You have a pretty strong natural scent, you know. After wearing clothes even once or twice, they need washing. It’s not like I was sniffing you on purpose—it just happened. Force majeure, okay? Of course, I actually like your scent! That’s why I swallow your cum every day, right?”
“…Haa. Thanks. Really, thank you.”
“Hohoho! Of course you should thank me! Where else are you going to find a wife like this?”
Chuu!
Iseul leaned in, blocking my view of the monitor. She closed her eyes and pressed her lips softly against mine. I held her so she wouldn’t fall, and we began kissing like we always did.
Chu! Chururup! Chururup! Chururup! Haa!
While kissing, Iseul leaned her body against me. Following her lead, I slid my arms under her back and thighs, lifted her from the chair, and stood up. She wrapped her arms around my neck, keeping our lips locked as I carried her to the bed.
I laid her down gently and climbed on top. Just as she cradled my head, I slipped my arms under her and held her head while we lost ourselves in a long, deep kiss, exchanging saliva before finally parting.
“Huu. Huu. Wife, my ass. When are you going to settle down and get married to some guy?”
“Heuu. Heuuu. I can’t even meet other men because of you, you know?”
“Kukuk. Aigoo~ Even if I do everything you ask, it’s all pointless~”
“Hmph! What are you saying! Then stop saying stuff like that and just fuck me already! Eit!”
Still holding me, Iseul rolled us over on the bed. I let her flip me onto my back without resistance. She began unbuttoning my pajamas, and I didn’t stop her.
She stripped off my top, then yanked down both my pants and underwear in one motion and tossed them aside. Now that I was completely naked, she skillfully spread my legs, settled between them, and took my already erect cock in her hand.
“You say you don’t like it, but you’re already this hard. Chuup! Chuup!”
“Huum…”
A blowjob on an entirely different level from what Eunhye had given began.
She sucked while tormenting the sensitive spots with her tongue and took me deep into her throat with practiced ease, instantly bringing me to full hardness and making me want to fuck.
While stroking her head in pleasure, she bobbed even more enthusiastically. But even as I enjoyed her skilled technique, the memory of the half-forced, clumsy blowjob Eunhye had given me surfaced and left me uneasy.
Even the slightest recollection brought vivid images of Eunhye’s breasts, ass, thighs, and pussy flashing before my eyes.
The body I had secretly touched and explored felt like it was still right in front of me—the smooth curve of her waist, the firm ass, the soft breasts.
The pleasure of cumming inside her this very morning came rushing back, and the reality that I could never have sex with her again felt unbearably disappointing.
Eunhye had been beautiful~ Her pussy had felt amazing too! The man married to a woman with a pussy like that must be so lucky.
Aish! I should’ve never known. If I’d known it would turn out like this, I wouldn’t have gone to that company dinner. I should’ve just held back.
While my mind wandered, Iseul continued diligently sucking me below. Eunhye was Eunhye, but Iseul’s skilled blowjob was impossible to ignore—it felt too good.
“Chuuup! Chururup! Chup! Chup! Fwaa! Chuuup!”
Her name was Choi Iseul. She was twenty-three this year (as of 2017), three years younger than me.
She stood in the early 160cm range—slightly taller than Eunhye—but her breasts were a modest B-cup, smaller than hers. Her hips, however, had widened from childbirth, giving her a broader feel than Eunhye.
Back then she hadn’t taken care of herself, so her figure hadn’t been particularly attractive—slightly misaligned and carrying extra weight. Thanks to my support, she’d been getting regular management and had improved a lot. Recently she’d started yoga, and her body was gradually becoming more toned and appealing.
The flab had disappeared, and she’d developed an apple-shaped butt. If you ignored her face, she now had the kind of voluptuous figure that would attract men who liked curvy women. The skin she got massaged daily grew more elastic with each passing day.
Her face was average, not particularly pretty. Her once-short hair had grown out to my preference and now reached just below her shoulder blades. At her age, she still had that bright, lively energy that made being around her energizing.
She wasn’t exactly my type, but she had plenty of charm. If she really tried, she could easily seduce any man.
Of course, comparing her to Eunhye was difficult, but Iseul had her own distinct appeal.
The one flaw was her three-year-old daughter, Choi Hanbyeol—currently asleep in her own room. In other words, Iseul was an unwed mother.
Unfortunately, the child wasn’t mine. It was the result of a mistake from Iseul’s younger days, a responsibility she carried alone. It had nothing to do with me.
Her education was another pity—she was only a high school graduate. Thanks to my help she’d passed the qualification exam, but before that she’d only finished middle school.
In a society that still discriminated based on whether someone had a college degree, finding a decent job had been extremely difficult for her. On top of that, she had a young child to care for, so making time was hard and the financial burden was overwhelming.
Before I started helping, she’d lived in a tiny rented room, relying on kind neighbors to watch the baby while she worked at a factory to barely scrape by. I’d occasionally given her what little pocket money I could, but it hadn’t been enough, and her health had gradually deteriorated without her realizing it.
Only after my crypto windfall did she finally breathe easier with proper living expenses. She began relying on me more and more. When I bought this house and moved in, she ended up living with me—half by choice, half by circumstance—and finally found stability.
My parents had worried about a man and woman living under the same roof, but perhaps they simply didn’t know how harsh the world could be. Or maybe they understood Iseul’s situation too well to object.
They never imagined we’d been in that kind of relationship for a long time, so they gave permission without much trouble.
Even now, they thought Iseul was just taking care of me while I lived away from home—cooking meals and keeping me company. They had no idea we were mixing bodies almost every single night.
That was why, when we started living together, my mother—who knew Iseul’s difficult circumstances—had actively supported the arrangement and praised me for it. With her backing, bringing Iseul into my home had been easy.
“Fwaa! Why are you lasting so long today? What the hell are you thinking about so hard?”
Iseul pulled my cock from her mouth, licked my stomach, then gave it a light bite. Looking up at me, she wrapped her right hand around my saliva-slick shaft and continued stroking to keep me aroused.
I stopped her hand, pulled her up into my arms so we were face to face, then rolled onto my side so we lay facing each other. Stroking her hair with my right hand, I spoke.
“Just… thinking about the problem you’re curious about.”
“Really a woman problem?”
“Yeah. That’s how it is.”
“Daa~mn. My brother who supposedly doesn’t know a single woman besides me finally got himself a girlfriend?”
Iseul exclaimed dramatically in my arms. She laughed and patted my chest, but after living with her for so long and sharing our bodies, I could tell she wasn’t happy at all.
Wrapping both arms around her, I spoke as gently as possible.
“Why? Not in a good mood?”
“…Tch. Of course not. I can’t live without you, but you’re thinking about dating…”
“You used to throw tantrums saying you’d marry me, and now you’re bringing a kid into it and saying stuff like this?”
“So what! Things are different now compared to back then. I was just immature then. And now? I’m the kind of woman who gets her number asked for on the street. Ahem!”
“Oh~ Then you should just seduce one of those rich guys and get married, right?”
“Hmph! Even among those people, there’s no one like you. Why do you keep trying to marry me off? Do you hate me now? Is that woman you slept with yesterday better? So you want me gone?”
“Huu… It’s not like that. Yeah. Let’s just clear this up first. I’m not dating. I just drank, made a mistake, and now the atmosphere is weird. I’m worried about work.”
At my words, Iseul pushed against my chest and lifted her head. She looked surprised, but I could sense she felt relieved and satisfied.
“Daaaaamn! Really? Wow! My brother became the kind of alpha male who just fucks women first? So who is she?”
“Team leader from another department.”
“Tsk tsk. Hang in there, bro. Just get that Naeil whatever-it-is and quit. You’ve already made a ton of money anyway, right?”
“Haa… I’m also wondering if I should really take that. I still have to work another year—how am I supposed to endure?”
“Kkalkkalkkal. You have to get that money, okay? I told you I’m using it for my wedding expenses! Mm~ You absolutely can’t quit for this pretty little sister of yours~”
Iseul laughed and snuggled back into my arms. She buried her face in my chest and rubbed against me, clearly in a good mood, and wrapped both arms tightly around me. I hugged her back and stroked her back and hair.
“Huuup- ha! Huuup- ha! Ah! I really love your scent, bro!”
“What scent? I already showered—what smell are you talking about?”
“You can’t smell your own scent. You smell mine too, don’t you? It’s like that.”
“Well, if you like it, fine. If your curiosity’s satisfied, go sleep now~ I’m going to sleep too!”
I pushed her shoulders away and sat up. As I moved to grab my pajamas, Iseul rose onto all fours behind me and hugged me from the back. She pressed her soft breasts against my back and spoke.
“Huh? No sex? I came all prepared like this and you’re just going to hold back?”
I could tell Iseul wanted sex just from the way her hardened nipples poked against my back. Unlike Eunhye’s, her nipples—darkened and firmer from breastfeeding—stood out prominently between her soft breasts.
“You know we don’t have condoms~ And today’s one of your dangerous days. Did you think I wouldn’t know?”
Ever since we started living together, our frequency of sex had increased dramatically compared to before.
Avoiding Byeol’s eyes was easy once night fell, and on days without special plans we’d often spend several days in a row tangled together—so much so that Byeol had even started giving Iseul looks, wanting to sleep together too.
Back then we’d used condoms even on risky days, but recently we’d stopped bothering and only did it raw on safe days.
We were familiar with each other, and raw sex felt better. If I was about to cum, I’d pull out or Iseul would finish me with a blowjob.
So aside from the one or two emergency condoms we kept for situations like yesterday, we didn’t stock any at all—and even those had all been used recently. That meant if we wanted to have sex today on Iseul’s dangerous day, we’d need to buy new condoms. Since we hadn’t, we were stuck doing it raw.
Of course, I had no intention of doing it raw with Iseul on a dangerous day.
“Whyyyyy~ I said it’s fine! Just cum inside. You know I like creampies~”
“You’ll end up pregnant with a second kid.”
“If I get pregnant, I’ll just have it. Having your and my child wouldn’t be so bad, right? We can just tell Mom it happened with some guy I was seeing.”
“This kid only says things I can’t handle. Why are you acting like this today, seriously?”
“Because I’m anxious! Anxious! Why! I’m scared you’ll meet some woman like today and abandon me like that guy did! You know that, so why do you keep asking!?”
At my words, Iseul finally exploded and shouted. I hurriedly tried to calm her.
“Hey… what are you saying. Even if I get married, I told you I wouldn’t cut contact or anything. We’re cousins to begin with—we’re not the kind of people who can just throw each other away. Of course, the kid and marriage… honestly, even having sex like this is something we shouldn’t be doing, and lately…”
Before I could finish, Iseul cut me off, grabbed my shoulders, and pulled me backward onto the bed. I didn’t resist and lay down. She climbed on top of me, pressing me down, and shouted again.
“Again! Again! Again! Talking back! You think I’ll accept it just because you say the proper thing?
Honestly, it’s true I’m tied to you financially because I have no money! Of course I know you support me with living expenses, pay for Byeol’s daycare, and even cover her lessons and activities!
But on the flip side, all of that is debt and burden to me, you know? So because I’m grateful, I at least offer my body to relieve your sexual frustration! If a kid happens, I said I’d just have it—so why are you refusing?
Are you impotent? Or are you tired of me? You barely touch me these days. And! When you’re right next to me, I have to masturbate with a dildo!!!!”
Faced with Iseul’s rare, full-blown explosion, I found it hard to respond.
So she was grateful enough to personally relieve my sexual needs with her body? I was grateful too, but a child was crossing the line. Besides, these days she was the one jumping me more often than I initiated…
It was true we’d been attached almost every day lately. No matter how high a twenty-something’s sex drive was, after this much sex the excitement was bound to decrease.
Was this a rut? Had we become sexless?
I wasn’t sure, but that kind of phase could happen to any couple or lovers, so it was natural it would happen to us too. And I thought that even if it did, it might help Iseul gradually become more independent from me.
But Iseul had been sensing these changes little by little and growing anxious.
Because she loved me and devotedly accepted all my sexual desires, she was sensitive to my gradually shifting attitude and was struggling with it.
On the surface she smiled and accepted everything I wanted, but the stress from that part had apparently exploded today.
There were plenty of things I felt wronged about, but I couldn’t even say I was wronged. Haa.
For now, I patted her shoulders to calm her down and spoke.
“Haa… You’re a mother… First, calm down…”
“Calm down what! You’re trying to gloss over it again! And! So what if I’m a mother? Does that mean I have no sex drive? When it was good for you, you fucked me whenever you wanted! Now that you’re tired of me, you barely touch me!
When I want sex, I have to beg you for it—what’s so weird about that? You’ve fucked my pussy, mouth, and ass in every possible situation—cosplay, SM, exhibitionism, outdoor sex—you’ve done it all, so now you don’t need me anymore? Is that it?
Am I just a slut to you? Or an onahole you use when you feel like it sometimes!! Huaaang!”
Finally, tears spilled from Iseul’s eyes. Water droplets fell from her pretty eyes onto me. Seeing her cover her face and cry, I raised the white flag.
I sat up, pulled her into my arms, and stroked her back and hair for a long time.
“Huk huk… Sniff!”
After some time, Iseul calmed down. I took her hands away from wiping her tears and licked them away myself instead. Left eye. Right eye. A kiss on her forehead, then on her cheek, and naturally we began kissing.
Chuu! Chuuu! Chu! Churup! Chu!
Once the kissing started, Iseul wrapped her arms around my back again. As we held each other tightly and kissed, she eventually stopped and calmed down completely.
Confirming she had settled, I pulled my lips away. With our foreheads touching, I smiled and spoke.
“Our princess. Have you calmed down now?”
“Hmph! You’re still trying to gloss over it.”
“Sorry for making you anxious. But you know, right? I’ll never abandon you.”
“Hmph! Anyone can say that!”
“Kukuk. No, really? When you marry another man later, I’ll call you behind his back and fuck you. I might even get you pregnant with my child. So I can never abandon you.”
“…You’re really a pervert. Hmph!”
I didn’t actually mean it, but my dirty talk seemed to have lightened Iseul’s mood.

She pushed against my chest with her actions and moved away to settle on the bed, but with a pleased hum she slipped the shoulder straps of her black slip down and off.
So she was planning to do it after all.
Crawling toward me on all fours with a seductive expression, Iseul’s face was already filled with excitement and anticipation for sex.
“And I know you’re worried about pregnancy too, right? Don’t worry—I’ll handle it. I still have the morning-after pill, and today…”
Iseul smiled suggestively and turned her body. Presenting her ass toward me, she spread her cheeks with one hand and showed me what she had prepared inside.
“…!”
“Today I prepared my backdoor to help you relax. You like fucking my ass, you pervert.”
