My Sister Would Love This Sort of Thing (4)
If I had to put a number on him, an 8.5 out of 10 was more than fair.
That didn't mean he was without his flaws.
"Something like that… I really don't think you need to practice it."
"…Your fingers…. Take your fingers out first…."
One.
He has no sense. Any ordinary person would have caught on by now, at least roughly, to why I was doing something this stupid—but that idiot still thinks this is practice. For the love of god, use whatever's sitting on top of that neck and think it through, slowly. What kind of angelic little sister in the world offers her older sister sex practice? Does that even make sense? …I'm only doing this because I want to cheat on her with you behind her back. The practice is nothing but a shoddy excuse. You moron.
"Hey, damn it, don't wipe it on my thigh…! There's a towel right there!"
"It's gonna get filthy with sweat in a minute anyway. Who cares."
"That is obviously gross…. …Kya…?!"
"Quit squirming and hold still. You'll fall."
"W-what, you mean we're going to the bed like this…."
"Yeah."
Two.
When I first met him, I thought he was just a nice boy. He's like that on the surface. Underneath, he's nothing but a lump of lust. Looking back, he's been that way since the very first time we practiced. Calling my sister in the middle of her convenience-store shift to tell her they should have sex; and when she said she'd never do that, calling the guy she'd been gaming with the day before instead and saying they should have sex—he's got quietly perverted tastes, you know? Almost as much as I do…? If even a scrap of sound leaked through the mic, they'd be caught on the spot, so why go out of his way to do it? What, did he want to watch me flail around trying to keep my voice in? Or did he want to see me finally give up, cram my panting moans into the microphone, and come? …Ugh. Perverted little bastard. Disgusting. Blech.
"P-put me down…! I can walk there myself!"
"…You were twitching like crazy a second ago. You sure?"
"It's right in front of us. What's so hard about…. Damn it…."
"…Fine. I'll put you down, so go to the bed."
But he was a man I'd given a full 8.5, and he had a few strengths that wiped those flaws clean away.
"…Hey. Seo Woojin."
"What."
"…You know. The teasing."
"Yeah."
"…I think we ought to practice it at least once…."
"…Do we have to?"
"I told you. Just pounding away like an animal from start to finish is boring as hell."
"When I called yesterday, didn't you hear Noona's moans…."
"I heard them. I heard them."
"…Yeah."
"…You don't know what kind of sounds she makes when she secretly masturbates in her room, do you?"
"…."
One.
No sense.
"She shuts the door tight, and you can still hear it all the way out in the living room. …Way louder than what you heard over the phone."
"…."
"So what do you think that means? It means fingering herself felt better than that intense sex she had with you. Okay?"
"…Mm."
He's so oblivious it almost feels stupid. Of course I've never heard what my sister sounds like when she masturbates. Unless she's out of her mind, she wouldn't get herself off loud enough to reach the living room while I'm sitting right there in the house. So all I'd done was spit out a lie that reeked, to anyone listening, of something thrown together on the spot. And Seo Woojin—
"…Fine. Do whatever."
—has no sense. Which makes him absurdly easy to twist around my finger. …Teasing isn't something only men can do, you know. A woman can tease a man just like this. And a Seo Woojin who's been teased to the brink, once the real sex practice finally starts…. …until I'm completely wrecked.
Thump, thump. A heavier thud.
…. …Hehe.
"Oh, right, um… …stand right here for a second."
"What. Again."
"If I tell you to stand, just stand…!"
"…Ha…. …What a pain."
"…."
"…."
"…Hey."
"…."
And Seo Woojin's second strength.
"…Don't. It's dirty."
"…It's fine. I just washed, how is it dirty…. And I'm playing my sister, remember."
"…."
"Lee Hayun would love this kind of thing. Wouldn't she? …She'd like it even more if she was forced."
"…."
"So obviously we have to practice this too. Lee Hayun's lower mouth or her upper one… if you're going to fuck her like a dog."
He's hornier than I thought.
"…Pfft…. Look how rock-hard you got…. I'm not your girlfriend. I'm your girlfriend's little sister. Hehe…."
"…."
"Ah, no, wait. Mmm~…. What would my sister have said…."
"…."
"…She probably couldn't have said a word. The second she saw it she'd go into heat and suck like her life depended on it."
The moment I knelt there obediently and carefully nuzzled my face into Seo Woojin's underwear, his cock twitched. The moment I, watching his face, started planting light little kisses on the bulge, his hand rose of its own accord to my head. …Enough that, without so much as asking, he gripped my head and pulled it toward him, press after press. His sex drive is strong.
"…Hey, your hands are awfully practiced…."
"…."
"Don't tell me you did this to my sister yesterday too. Like… yanking her head so she'd suck your cock."
"Not yanking. …A little."
"…You two really are a pervert couple. Yesterday was your first time, and you're already into that kind of play…."
"…."
"Anyway, good job. Lee Hayun would love that stuff."
"…Yeah. She did."
"My sister likes collars too, you know? Getting her leash yanked tight by a guy while he takes her from behind… and also…. Oh! Choking her while he fucks her is pretty—"
"I'll keep it in mind. So, Jiyun… …that…."
"……Ah. Right."
"…."
"I get it, so stop pulling the back of my head. Idiot."
"…."
"Boring bastard…. Hmph…."
I got carried away for a moment and blurted out every last one of my sister's porn tastes. Kneeling with both hands braced on the floor, I closed my eyes to slits and sniffed—sniff, sniff—at the smell of my sister's boyfriend's cock through his underwear. …Ah, shit. Seriously. I shouldn't like this. Still, lucky for me, to Seo Woojin it'll only look like I'm pretending. The one kneeling here isn't me, anyway. It's Lee Hayun. I'm just the angelic little sister cheering the two of them on. Mm-hm.
"…Phew…."
I catch the underwear, gone a little damp from all the kissing, between my lips and drag it downward. What's hidden inside is so big that it's a struggle… but if I use my teeth as well, I can manage somehow. It snags on the head and won't come down. I bite the edge and force it the rest of the way. …And then the same thing that had been left last in my head—seeing it again, it might even be a little bigger—an absurdly thick cock, veins standing out in hard ridges, and a sac so plainly packed full of semen, twitch above my face. Wet with precum, giving off a lewd smell.
"…."
"…."
I feel like I ought to say something, but it won't come. Something bright and lively, the way my sister would—Wow, look how swollen your cock is. Pfft. You wanted me to suck it that bad, pervert? …or something like that? Or completely businesslike—I'll hold still now, so pretend I'm my sister and force a blowjob on me. If I feel like throwing up, I'll tap your thigh. …or something like that? It isn't that I don't have ideas. It's more that I'm being overwhelmed. By nothing but that one cock.
"…Blehh…."
"…."
I give up on talking. Instead, so that even an idiot could understand, I push my face in front of the head and stick my tongue out. Ah. No. If a cock that size is going in, I need to drop my jaw wider than— …Wait. Hey, what are you doing, shoving it in all of a sudden—
"…Kgh, mmph…. ……Hnngh…."
The precum smeared thick over the head dirties my tongue. A second later it paints the smell across the roof of my mouth, and as if that still isn't enough, even the narrow entrance of my throat—thump, thump—as he pounds his cock in rough and marks it with precum. As if he's branding me Seo Woojin's property. My mouth fills with his smell.
"Nngh…. Kehk, ghk…. …Mp…. Hnngh…."
I want to suck hard enough to make him feel good, but… I can't. I wonder if I ought to lick the tip of the head with careful devotion, the way I saw in those dirty comics, but right now all I can do is let my tongue hang there, so that's impossible too. In the end I only drool in a long string off the tip of it and make a mess of the floor, hands braced on Seo Woojin's knees, used like a toy. …Not even all the way in. Not even halfway. Blech. Blech. Gagging the whole time. I become a new toy in my sister's place. Well. Compared with her, I am the newer model. Seo Woojin would rather have this than something worn out. Hehehe….
"Schl, hnnn…. …Nngh……."
Ah. So if someone pounds your throat like this whether you want it or not, the tears come anyway. I blink until the haze whitening my vision clears, then glare up at Seo Woojin, who has to be looking down at me. I heard it somewhere. Guys like it when a girl looks up at them with no manners in the middle of a blowjob. Especially with bloodshot eyes and tear tracks on her cheeks, staring up like I'm going to kill you. They love that. It's a guy thing, but even I can roughly tell what the feeling is. …Conquest. Every Western porn video felt exactly the same. Predictable.
"…."
Had I guessed right? When my eyes meet Seo Woojin's—he'd been busy hauling the back of my head in—he gives me a smile so faint you could almost miss it. The smiles I usually saw from him were nothing but kind. …The one I see now is a smile anyone could read: he's looking forward to fucking me. At that smile I stupidly twitch my thighs, and with the tongue that until now only knew how to drool, I try my best to lick the base of his cock. So I am getting used to this. Makes sense. In porn they slam it all the way down the throat. It'd be strange if you didn't get used to it.
"Hngh, hak…. Haa…. Ha…, …why'd you pull out. All of a sudden…."
"…Thought you might be choking. Figured I'd let you breathe for a second."
"Then I'll just smack your thigh as hard as I can, so don't worry about that crap and keep shoving your cock in my mouth. …Coward."
"…."
"That Lee Hayun, a masochist who only likes it when she's treated rough…. …Mp, kgh……."
The dry look from a moment ago is gone. The cock is soaked in my spit, a cloudy ring already formed around the middle. I grip the base tight in my fingers and lick, lick at the head, swollen fat because he wants to come—and the breath he'd been panting out is crushed without mercy by that thick, long cock as he drives it back into my mouth.
"Hahp, schlp……. …Bleh…. Nngh……."
I can't breathe. Every time the head pounds against my throat, another dry heave climbs up. And all the while tears keep leaking out, shameful, running down my cheeks. Even so, afraid Seo Woojin might misunderstand, I lower the hand I'd had on his knee. …Into the cunt that had been busy making a sticky mess of the floor, I jam my fingers, slick and wet. My heart is pounding so hard my eardrums ring. Unlike my sister, I'm not particularly into masochism. But behind her back, with her boyfriend, cheating under the excuse of practice—
"…. ……. …Nngh. ……Hp…."
—in place of my sister, off somewhere having fun with her friends, with a cock stuffed into my mouth as deep as I can take it, gulping and gulping down her boyfriend's semen—this situation was completely my taste.
