Practice Sex (6)
"…You still don't get it?"
"You— you…"
"Rubbing your walls with rubber, and rubbing them skin to skin. Feels completely different, doesn't it."
"…Ah, don't talk while you're pressing— there, ah…"
"For my part… this way feels way better."
"Hik…"
"Looking down at how soft your ass is while I slam it in raw— the conquest is fucking insane."
"Shii… nngh…"
I tried to twist around and snap at him while he worked his cock into me at that slow, deliberate pace, but my body refused to cooperate. Whenever I was on the verge of coming and spilling those stupid little hiccuping sounds, he scraped my walls gently, almost kindly. The moment I started to feel even slightly composed again, he drove his hips into my ass with wet, heavy smacks and forced himself in to the root, as if he meant to break me all over again. When I tried to pant out a word—hff, hff—he seized my shoulder and pinned me down, pounding my womb to pulp with a steady kung, kung, kung. And when I finally gave in, face-down and trembling, trying to endure the climax crashing over me, that gentle voice poured into my ear once more.
Pinned beneath Seo Woojin, all I could do was mutter some stunted little curse every time his glans knocked against the mouth of my womb.
Instead of my sister, who still didn't know a thing—
I, the little sister,
was being used as her boyfriend's masturbation toy and fucked.
…When you jerk off,
you don't use a condom anyway.
"Yeah. You're definitely reacting better this way."
"F…uck… pull it out already…!"
"Pull what? What am I pulling out?"
"What else would I be talking about right now… obviously your c…ock…!"
"When was your period?"
"Cut the bullshit and— hurry up and pull—?! Hik—?"
When was my last period, again.
How do you even calculate safe days.
If Seo Woojin slipped and came inside right now, would I be okay?
…What did they say the odds of getting pregnant on a safe day even were?
The thoughts spinning in a tangle came apart in a miserable wreck after just a few of his strokes, driven in to the root.
Thud.
Thud.
Thwack.
An overwhelming pleasure that left no room for anything else. So even as my mouth yowled at him to pull out, I was still being stuffed full of that bare cock on the edge of coming, and all I could do was string slick female slick endlessly between my thighs.
"…You crazy bastard… r-raw, you can't, nngh… you can't do it raw…"
"Why not. Say it straight. So I can understand."
"If you want a straight answer, then stop shoving your cock in first…!"
"…Cock. What."
"…Nngh, just— j-just a little slower……"
"…Talk. Now."
"You piece of— …nngh…"
What was I supposed to do if I actually got pregnant like this?
That was the scariest part, no question. But he didn't seem to care about any of it. As if granting my plea to go slow was too much trouble, he eased off by the smallest fraction—just a sliver—and kept driving his hips like he meant to pour me full to bursting, glug after glug.
…The way his cock twitched every time he paused. The way his breathing had gone so much rougher than at the start, after coming more than ten times already. It wouldn't have been strange at all if he buried his glans against my womb right now, bit down on my ear, and started spurting. My sweat-slicked back tightened in a cold shiver.
"Lee Jiyoon. …Be honest. You like this better too, don't you?"
"Shut… up…"
"You're coming closer together than before… you feel it too, at least a little, right?"
"I said shut up…"
I didn't know. I didn't know how bare sex without a condom was supposed to feel different, and I didn't really know whether this was so much better than a moment ago, and I couldn't make sense of Seo Woojin's voice, that faint little laugh about how my climaxes were coming faster.
If anything had changed, it was my head.
The worry that if Woojin slipped, and if my luck was rotten on top of that, I might get pregnant. And the fact that I'd gotten to no-condom sex so much sooner than my sister, his actual girlfriend— and that I might even end up pregnant—
…That…
…filthy, rotten sense of transgression.
But I couldn't go cutting open the goose that laid the golden eggs over one guilty thrill, could I?
As long as I didn't get pregnant, as long as Lee Hayun never found out about us, as long as the cleanup and the silence held— then like this. While our innocent Hayun boiled stew at home, oblivious, I could keep having affair-sex at Woojin's place until I was good and satisfied.
So I bit down hard on my lower lip, scrubbed the former thought out of my head, and flailed one hand back, trying to make him stop.
…But of course.
"You were holding out a little earlier. Now you're coming almost every thrust."
"…I-it's not that bad…. Don't exaggerate…"
"Every. Thrust."
"…?! …??! W-wait a sec……"
"You're coming. …Hard enough to tie your tongue."
"…Heek……? Heh…?"
A completely useless rebellion.
"…Ah. Fuck, seriously…. Your reactions alone are stupid hot."
"Get… off…, mmph…, bleh…"
"Hff…. You look like you've got a rotten personality written all over your face…. And then you whine under me, and it's stupid cute."
"Chk…, …mmph……"
Useless. Truly, completely useless.
If I had Lee Hayun's strength, maybe. A girl who spent her days gaming at home was never going to shove aside muscle that solid. If anything, my feeble resistance just turned him on—he slammed in with everything he had, forced my face around, and kept the kiss going.
So I clenched the sheet in both fists, determined not to let him catch another climax, and poured every panting breath straight into his mouth. Breathing hard like that, his saliva slowly spilled into me, and I swallowed it down—gulp, gulp—mixing it with the spit already pooled in my throat.
…Well.
Honestly, whether I fought him rough or went quiet and obedient, he clearly had no intention of pulling out.
If I had to pick, though— this was more my taste.
"…Hoo…. I'll finish outside, so can we just keep going like this?"
"Shii… if that's the plan, just use a condom…! What's the difference. Coming outside or coming in a condom…"
"I'm telling you raw feels way better. …You like this better too, if you're honest."
"…Not really…. There's barely any— nnh— difference…"
Even thinking about it now, I still didn't get it. The only thing that had changed from earlier was my attitude. Him saying I felt it more because it was raw—
….
…I don't know.
Seriously.
It's the same as before.
I know my own body best.
"You were flinching and coming every time you heard that wet slap of my cock going in, and you're gonna sit there and say 'not really,' fuck."
"I'm not…! A-anyway…. Put the condom back on…. That wasn't the last one, was it? I'll open the wrapper. Hurry…"
"Let's just do it. Hm? You've been squeezing so hard this whole time the condom keeps trying to slip off. Jiyoon."
"I-I'll relax…. …Eh……?"
I didn't even really know how to relax, but I'd decided the worst outcome had to be avoided, so I fumbled for the condom box and started tearing at the packaging—when Woojin let out a heavy sigh above me.
He snatched the box out of my hand, and then, so I couldn't pick it up again, he flung it carelessly far across the bed.
A light clatter. A soft slide.
The sound of the discarded box rolling a few turns across the floor and skidding away reached my ears—while a cock wet with nothing but precum and my own slick, no rubber, no lube, rammed into my womb like it had lost its mind.
"You cra—zy bastard……. I said use a condom…. Nngh…"
"…Better to pull out when I finish than to kill the mood putting a condom back on, right?"
"What if you mess up and— nnh— come inside…"
"That won't happen."
"What do you mean it won't— hik……. S-stop…"
The Seo Woojin I'd first met, dozing for a moment in the infirmary, had definitely been kind. The Seo Woojin who'd come looking for me at the café during my shift, because my sister asked, had been kind too. The Seo Woojin who'd asked me this and that because he wanted to look good for my sister had also been kind. Even when the three of us—Lee Hayun, Seo Woojin, and me—went shopping, it was the same.
But a Seo Woojin whose head was soaked through with lust was a little different. Less kind than playful. A man who did as he pleased.
…He hadn't been like this when I eavesdropped on him having sex with Lee Hayun yesterday.
Seeing his bare face one step ahead of my sister scratched a dirty little superiority across my heart.
Didn't I want to see him a little more honest than this.
Didn't I want him thinking about me—the girlfriend's little sister—more than the girlfriend herself.
Didn't I want him treating me as more important than some trivial date with her.
Then there was only one way.
…The one way that had just surfaced in my head.
"Hoo… seriously, if I'd known it felt this good, I would've tried it without a condom way earlier…"
"…Hey. Seo Woo…jin."
Flat on my stomach, belly pressed to the sheets, he drove his cock in to the hilt and kept spilling filthy words into my ear. I caught the arm braced firm beside me and offered my voice, careful.
"Yeah."
"…You really are gonna finish outside, right?"
"…"
Permission.
Permission to go without a condom.
Permission with one condition attached: he would come outside.
The moment he heard it, Woojin breathed a small sigh into my ear, grabbed my ass—busy twitching from the pleasure—and pushed his voice in one layer deeper.
"…Is it because it's a risky day?"
"…"
I'd swallowed my embarrassment and barely managed to allow him that much, and now, absurdly, he wanted more.
…Like he wanted to come inside.
Buried to the hilt, he ground his cock against the mouth of my womb and spoke.
"Why aren't you saying anything. Just lying there. …Too embarrassed to talk?"
"…Why are you even— asking that…"
"Because I'm curious."
"Bull…shit… you just want to come inside me, …hik…. You asked because you want to come inside, didn't you…!"
"…If it's a safe day, it doesn't matter anyway."
"It does matter…! It doesn't mean you absolutely can't get pregnant, so— nngh……"
"And you…. Getting it inside would feel better than getting your back dirtied."
"Shut up, you crazy bas—. …Hiik?! No, no, no…. Don't go fast…"
I tried to persuade him with perfectly ordinary sense, and got nowhere. If anything—
Thud.
Thud.
He pounded like he really meant to finish inside, trying to wreck my head with unreasonable pleasure until I turned stupid.
"So. Can I come inside? …Or not?"
"N…o. Absolutely not…"
No.
I was pretty sure I'd answered clearly. The cock scraping roughly along my walls, pulling out and then sinking, fwoop, fwoop, into the deepest place, didn't change at all. He buried me up to the crown of my head in pleasure, driving me to say yes instead of no, and never once pulled me back up.
Like I was supposed to stay sunk in that mud and never climb out.
Relentless. Sticky.
"Today's a safe day for you, though. Isn't it?"
"Don't say weird stuff, just finish outside…!"
My shoulders jerked. For a second I reacted—and before Woojin could notice anything off, I shot him a glare through eyes that had gone a little slack.
Ha. Cheap tricks like that don't work on me.
Do you even know my cycle?
And you're just guessing anyway….
What if I lied and said all thirty days of the month were risky?
You idiot….
"If it were a risky day, you wouldn't have asked why I was asking earlier. You wouldn't have said a safe day still isn't a hundred percent. You'd just say it's a risky day."
"…That's just you assuming, …nngh… got it…?"
"So we're having sex without a condom on a risky day?"
"……"
The only thing that was actually wrong was "risky day."
But if I agreed, it'd be obvious I'd let him fuck me raw on a dangerous day, and I'd get treated like a pervert.
I was looking for a way out, but my head kept shorting out from the pleasure.
I couldn't say a word. I just stayed face-down and hugged the pillow already soaked through.
"And you're the one who allowed it. …When you don't even know what might happen."
"I didn't allow it…! I— I kept telling you to use a condom…!"
"Idiot. If you'd said use a condom because it's a risky day, you think I wouldn't have?"
"…"
"When I asked what the problem with doing it raw was, do you remember what you said?"
"…"
"…Not once did you say it was a risky day. Do you remember. Lee Jiyoon."
"…"
"All you did was parrot elementary-school sex ed. 'You have to use a condom.'"
"…"
"…Pervert. Lee Jiyoon."
"…"
The cock that had been pounding in, fwoop, fwoop, paused, clenched tight by my walls, and twitched.
Every word Woojin whispered in my ear meant the same thing: he wanted to come inside me as much as he liked.
I wasn't even being fucked anymore. I was just lying there, and the light climaxes wouldn't stop.
Squelch. Squelch.
He sat up and slid his cock in far more gently than before, and still my shoulders jumped for a long while as I came.
My body had gotten sensitive.
"…Lee Jiyoon."
"…"
"Is today a risky day?"
"…"
The same question as a moment ago, his voice stroking my ear, affectionate. His cock, though, clearly had no such intention.
Telling condom-sex from raw sex on the spot was still too much for me. But how hard he was— that much was easy.
He'd only gotten this hard once before, when we'd had sex with the Discord mic on….
….
…Ah.
Now that I thought about it,
this might be a little bigger than even then.
"…It's a safe day."
"…Yeah?"
The moment I said it myself, clear and certain, Woojin let out a small sigh like he was steadying his breath and slowly changed position. Bracing on his forearms ended there. Instead of staying close enough that turning my head would land a kiss, he planted a fist on the bed and drew much farther back.
Except for my ass and his lower stomach.
Those stayed close.
…Close enough to bury himself to the root and come.
"…Then it's okay if I come inside?"
"…Do whatever you want…. Dumbass…"
"…"
"…You already came that much earlier, so I probably won't get pregnant or anything…"
"…"
"…What are you doing? …Getting cold feet now?"
Hearing an answer that blunt, Woojin pulled his cock out of me for a moment.
Then something landed with a soft tap beside my face.
"…"
…A condom.
And a very wet one, like it had been on until just now.
Clear precum smeared thick along the tip.
That kind of condom.
Before I could even ask what the hell this was supposed to be—
Woojin—
"……?!? …? ……. ………♡?"
—shoved his actual bare cock deep inside me.
How hot it was.
How hard.
How much the veins stood out.
How worked up he was.
All of it came through, properly.
A real, raw cock.
"…Hoo…. Fuck…"
"…Hek…. Heek…?"
"…Rubbing with rubber, and rubbing skin on skin. Feel the difference now?"
"Hik……, hiik…? Nnh, ut…?"
"…I can feel it for sure now."
"Haa…, ah……"
Different.
The cock that had been wrecking me a moment ago hadn't been this hot. It hadn't been this hard. I hadn't felt every vein like this. I hadn't felt him this worked up.
…Sex with a condom on felt like nothing but "sex practice,"
it was that completely different.
"Which do you like? You."
"……I don't knooow…, you bastard…"
"Don't swear. Pick."
"Pick what…! Shii…"
"If you like the condom better, go pick up the one I just threw on the floor."
"No condom…. No condom is— nnh… way better…. …Happy now…?"
Even the light little squelching thrusts were different. Burying deep and stirring the tip around was different. Woojin panting hot breath over my head and slamming his cock in like an animal was different enough that all I could do was hook my tongue over my lower lip and heave.
My waist kept jerking up. My stretched toes kept curling.
Was it even possible to last through this without passing out.
It hasn't even been thirty seconds and I already can't see straight.
White, and black.
…I don't even know what color this is anymore.
Ehehe.
"…Ha, you crazy bitch…. Take one condom off and you clamp down harder than before, fuck."
"I don't know…, hak…, haa…. Wait, I need a break…"
"It hasn't even been a minute. What break, idiot."
"Break every minute…. My head's going weird…"
"Sex is for making your head go weird. Why would I give you a break?"
"Shii… just come already…. My head's really going white…"
Maybe bringing up a break had been a mistake. Or maybe telling him to come fast was the problem. The movement I'd thought was already animal a moment ago got rougher still.
Pinning my twitching waist and thrusting wasn't enough. He stayed buried to the hilt and ground the precum-slick glans in circles against the mouth of my womb, like he meant to stir up my insides. Then the pistoning started again, and he grabbed the hair I'd been panting into the pillow and yanked it from behind so I had to look forward.
And then—paang, paang.
He started crushing, without mercy, the space that would have to hold his cum.
I'm a person, not an onahole or a love doll.
If I actually broke….
…Ah.
You can just fix me.
"……, …? ……♡ …………"
Anyway, so—
that aside.
The hair you're pulling. Could you let go?
It's not like a kiss could ever reach from here. Why are you pulling?
You don't like my face buried in the pillow?
…Ah. Maybe you just wanted to hear me yelp like a bitch in heat while you fucked me.
Judging by how you got off yesterday hearing my sister call you oppa….
That must be your thing.
"…Lee Jiyoon."
"Hek, heek…"
"I'm really gonna… hoo… come inside?"
"Mmhm…, nngh, hik……"
Well. That much I could do for him.
Lee Hayun calling him oppa, or imitating a puppy— it wasn't all that different.
Just this once. A special service.
"…Woof…. Pffhihi……"
"…"
I barked on purpose, cute and loud, for a Woojin who looked like he was enjoying himself. I wanted to wag my hips and tease his cock too, but he was already pounding too hard for that.
Instead, while the strength left his hand, I glanced back and gave him a wicked little smile.
I don't smile because there's nothing to smile about. It's not that I don't know how.
Keep it in your head. Treasure it.
I really don't smile as much as you'd think.
…I smile sometimes in front of you, so maybe it doesn't matter?
Whatever. I don't know.
If I say keep it, keep it.
Hehe.
"…You insane?"
"…Woof?"
"…Crazy bitch."
"…Woof woof. Woof woof woof."
Had my service landed?
Muttering that I was a crazy bitch, Woojin grabbed my neck in one hand and rammed his cock in like he'd lost his mind.
Cheering him on felt weird. Saying I hated it was too late—I'd already spilled half of what I actually felt. And saying it felt good, asking for more, was too embarrassing to do out loud.
So I forgot this was only a modest little studio, and let every sound tearing out of my lungs go free.
…Until the cock buried inside me
started spurting—
spurt, spurt, spuuurt….
Until it wasn't trapped in rubber,
until it pooled deep in my body.
Until Woojin, still coming, knocked the mouth of my womb with his glans again, kung, kung, like he meant to lock the fresh cum deep inside.
Just like that—
spuuurt,
spurt,
spuurt,
a thick, rolling pour….
Until I heard the sound of my womb being filled, heavy.
Hek, hek, hek.
I let the animal moans pour out as much as I wanted.
"…How is this much cum already running out the second I pull out."
"Heek…, heh……. You're the one who came, dumbass…"
"You're the one who milked it. Enough to wring this much out after I already came more than ten times. …Crazy bitch."
"…You're the pervert who came a lot……. Nngh……"
"Lie on your side for a second? Watching it run down your thigh and ass is hotter than just letting it drip."
"……Hmph…"
"Good. Like that."
"……"
Click. Click.
The light sound of a camera shutter. Right after, the phone—screen lit—landed on the condom he'd tossed beside me, the one that held nothing but my slick.
A pussy swollen faintly red from so much sex. Because I was on my side, an absurd amount of cum running down my thigh and over my ass. I stared blankly at the photo of my cunt, cum glugging out of it, until Woojin—who'd stepped into the kitchen for cold water—came back and settled beside me.
"…You're not gonna clean up?"
"…"
A cock that still looked like it could come a few more times.
A cock filthy with the cum he'd just shot, smeared all over it.
…The monstrous thing that had pressed into the depths of my walls again and again, something that cleared my sister's little handspan, and mine, without even trying.
He held it up over my face.
"……"
…Obviously—
Seo Woojin's cock
was soaked through with the taste of rubber.
