Doing Something Bad (2)
…You kissed me first, without even saying a word. You were the one who got sly about it—hands on my waist, dragging them up so lewdly my spine went cold and electric—and then you yanked my bra up, the kind that comes undone with a single little tug, and started kneading my soft nipples. You did the bad thing first.
All I did was… just help you practice fucking my sister. That's it. So I only called you a virgin bastard to piss you off. I already knew that later, on this bed, at your place, somewhere, behind my back, you'd be having sloppy, soaking sex with her. I was just teasing you on purpose. And then, somehow…
…i-is your d-dick… small?
…it just kind of followed on its own.
Ah, ahaha…. I'm joking. Joking. Did that upset you? Virgin bas—
"……."
"……."
Clink. Clink.
A sound I'd never heard before—a man undoing his belt—came thundering in. He had my wrists gathered above my head and pinned hard, so I couldn't even cover my ears, and from on top of me he looked down like he meant to eat me alive.
Clink. Clink.
"…Hey. Seo Woojin."
"What?"
"…N-no sex. You remember, right…?"
"I never said a word about having sex. I asked if you wanted to see my dick."
Right. That's true, but… just in case. I felt like I needed to make it clear one more time.
If all we're doing is this 'practice,' I can sort of claim I'm still in the clear. But if I actually go and… have sex with my sister's boyfriend, then it becomes a real bad thing.
I don't want to do bad things. I really don't.
"Th-then you can take them off. Your pants."
"I was already taking them off. Saying that now doesn't change anything."
"A-anyway…!! …I'll at least inspect it for you."
"Inspect?"
"I know what kind of porn my sister watched. …The d— …I roughly remember how big the things in those were."
"Fine. Do whatever."
"…Hurry up and thank me."
"Thanks. You little virgin."
"…Virgin bastard."
Seo Woojin only chuckled, like the same insult didn't even scratch him anymore. His fingers fumbled, and the pitch-black slacks slid down to his thighs—men's underwear, thin, the first I'd ever seen in person. For a moment I was thrown by the long bulge hinting sideways from the center.
"……."
Then, with a soft flop.
Different from what I'd pictured—from the rough guess of it probably looks something like this—a little different from everything I'd seen in porn and every other piece of fiction.
…An enormously large cock.
It cast a lewd shadow across my lower belly. From the place with the narrow little hole, all the way to my navel. Right up to just beneath it. Vulgarly. Grotesquely.
"Hey. Lee Jiyoon."
"……."
"Jiyoon?"
"……."
"Ah—should I be calling you Hayun-noona right now?"
A length like that—my handspan wouldn't even cover it, would it? A handspan. A handspan is… probably… eight inches. More than that? Or not?
…Anyway. So if I had sex with Seo Woojin, that thing would push in all the way under my navel and crush my empty womb to a pulp.
Thud. Thud. Thud.
…Squelch. Squish. Stuffed full. And then—gulp, gulp—overflowing….
Unnie. Would you be okay.
"Is it small?"
"…Huh? Wh-what?"
"I asked if it's small. Noona."
"…S-small? This? And Noona…? Ah, that…."
Seeing me babble at the sudden question, the corner of Seo Woojin's mouth twitched. I didn't understand the look for a second, but after about five seconds it hit me late. That was obviously the face of someone desperately holding in a laugh.
…Bastard. He definitely knows his dick is huge, and he's doing this on purpose…!
"I don't really know how big other guys are."
"…You'd know if you watched even a few porn videos, you dumbass!"
"I only look at the women's bodies. When would I have time to stare at some guy's cock? I'm not gay."
"……."
"So. Is it small?"
…What a real bastard. There's no way he doesn't know, even if he doesn't care about other men's bodies. He just wants to hear the word 'big' come out of the same mouth that was teasing him a minute ago. I knew guys were childish, but this much…. How is a twenty-year-old no different from a ten-year-old kid?
I stared up at his smug smile for a moment. Then I snuck a glance at the cock, thick veins standing out along it.
"…I-it's average?"
"Yeah?"
"Yeah. Every dick I saw in porn was about this size."
I spat that out and forced a relaxed smile.
I'll be childish too. I'm absolutely not giving you what you want. Bleh.
"Still, you're saying it's not on the small side."
"……."
"Right?"
"……."
…Is my IQ on the level of a beast? I used to do pretty well in school, for someone who games this much….
"…Think whatever you want."
"Shame. I thought this was plenty…."
"…H-hey…! Wait…."
"I thought I was on the bigger side compared to other guys."
While I was busy marveling at my own lacking intelligence, Seo Woojin—still pinning me like he meant to devour me—started tapping something hard against my bare skin. Over jeans that were, for now, still intact. On my stomach, fully bared because he'd shoved my top up just to cop a feel of my chest. Like this. As if branding into me that if he shoved it in, in this shameful mating position, it would reach all the way here.
…R-right. Well. Up to there, I don't particularly care.
Every time the head of his cock touched my stomach I clenched without meaning to, and no matter how badly I wanted to act indifferent, my cheeks kept burning.
Sex with my sister's boyfriend, behind her back. By any normal standard, there's no way she'd ever forgive me. I know that, and yet every time his cock touches me, these bad thoughts keep popping up. As long as Unnie doesn't find out, isn't that enough? It's like a devil in my head is whispering it. Usually an angel shows up beside you to argue back. Why is there only a devil in my head? Get out. All of you. Die.
"I-it is average…."
"If I shove the whole thing in, it'd reach here, though. That's average?"
"…Pfft. Shove the whole thing in. Girls don't even like that. That's such a virgin way of thinking."
"No—I'm asking if it's average. …And you're a virgin too, so how would you know?"
"Use your head. If something that huge came in this far, of course it would hurt."
"Didn't you just say it was an average size? Have you been drinking?"
"…A-anyway…!"
Rambling. A mess of words that didn't even make sense to me.
Let's just do it behind Unnie's back. That Seo Woojin clearly wants to, too. Look how stiff his cock is—he's not excited over Unnie. He's excited from touching my body.
The devil shoving at my back made my head spin, but my resolve stayed firm. Sex was absolutely not allowed. Because it was a bad thing.
…But.
"…Let go of my wrists for a second. Move over."
As long as it isn't sex.
"…Close your eyes. No—turn around and face the wall."
"Why all of a sudden?"
"Hearing you say you're going to shove the whole thing in—I can't. It makes me too anxious."
"…So why do I have to face the wall."
"Because I'm going to give you sex practice before you do it with Unnie, so face the wall…!"
So. If it's only sex practice.
"It should be around here somewhere…. …Ah. Found it."
It's… okay, right? Unnie.
"…You're going to stay like that the whole time?"
"…Shut up."
"If you're that embarrassed, you don't have to. When I do it with Hayun-noona, I'll be gentle…."
"…I said shut up."
After that bizarre declaration of sex practice, the smile wouldn't leave my mouth. Lee Jiyoon was doing the exact same things as her sister. Clutching a pillow tight to hide her face because she was embarrassed—a perfect copy of what I'd seen during Lee Hayun's first time.
The deep green eyes, too. The way both of them get sweetly tipsy off a single can of beer. The way their sensitive spots cluster thick in front of the womb. Sisters who look quite different on the surface, and yet they resemble each other in more ways than I'd expected—and I'm the only man who knows it. That's fun.
"So. You're really going to do it?"
"…Do it before I change my mind."
"Can I hold your thighs?"
"Stop asking every little thing…! Just put it in, damn it…."
Lee Jiyoon, mumbling her anger with her face hidden behind the pillow. I moved in on her where she lay with her thighs pressed together, and knelt in front of her. The bed creaked, and the way she went quiet at the same time was cuter than I'd expected.
The Lee Jiyoon in my memory, the one they called Witch, had been a woman who suited coldness far more than this kind of cuteness. Maybe because I'd figured out that was nothing more than her being shy around strangers, this side of her suits her much better now.
"What are you going to do if you get Noona's clothes dirty?"
"I'll just wipe them off and throw them in the washer."
"So you had no plan at all."
"…I've got a few more pairs of dolphin shorts anyway. It won't show."
As she said it, Jiyoon—embarrassed, maybe—kept tugging up the dolphin shorts she'd just changed into. Her sister's.
So. She says she'll give me sex practice, wearing her sister's dolphin shorts, and tells me to pound my cock between her thighs. A little late to say it, but I have to wonder if this counts as a normal conversation. No matter how I look at it, she just looks like a little sister lusting after her older sister's boyfriend.
"You'll be embarrassed too, so I'll finish quick."
"…I-I'm not embarrassed at all…. Are you, maybe, conscious of m—"
"Put the pillow down before you talk."
"……."
"Relax your legs. Drape them over my shoulders. Like this I'd have to fuck your calves."
"…O-okay…. Here…."
People are animals of adaptation. The hard part is trying something the first time; steel yourself and get through it once, and everything after is nothing. Stealing, say. Preparing to fuck a hero. A secret tryst with your sister's boyfriend, behind her back. It's all the same.
Today, thigh-sex. Tomorrow, a handjob. The day after, penetration. The day after that, a creampie. The day after that, pregnancy. If I were giving an example, it'd go something like that. I have no intention of jumping the schedule that far, of course.
…Anyway.
"Hah…."
"……Nnh…."
I gathered Lee Jiyoon's snow-white, smooth legs together and pushed my stiffly erect cock into the narrow gap between those soft thighs. Part of me wanted to ignore everything she'd said and just pound into her…. I'd try that later. When she was pulling this stunt while using her sister as an excuse, if I whispered in her ear and asked what she'd been thinking, I bet the reaction would be pretty fun.
"…Want me to put more in? Or just this much?"
"…H-how much did you put in…?"
"Roughly…. A little over half. Just enough that it doesn't stick out past your thighs."
"……Wait a second."
Still clutching the pillow tight, she said that, then carefully brought one hand to her thigh. Was she thinking of rubbing the head with her palm? I was vaguely imagining that when, instead, her hand squirmed sideways along her thigh. And then she measured the thickness of her thighs, pressed flush together, and with her fingers spread just that wide, gently laid them against her lower belly. So she could measure the length. Gently.
"…Hey. Seo Woojin."
"Yeah."
"You said you put in… a little over half, right?"
"Yeah."
Thumb set against her navel, she moved her spread pinky downward until it touched her pussy—down, barely an inch or two past the navel—and roughly estimated how far it would go if they had real sex like this.
And she—
"J-just put in that much…."
"……."
"If you put in more…. She'd definitely break. …Unnie."
"Yeah?"
Not even to the root. At a length of barely over half, she waved a little white flag and tucked her tail. And in the middle of that, she didn't forget to stuff her sister into the excuse. So damn cute.
"…Yeah. So now… try moving slowly. I'll tell you if something's weird."
"I love you."
One line.
"H-huh…?"
"I said I love you. Noona."
"Ah, th-that, ahaha…."
"……."
I said it on purpose. And then—
"I-I also…. ……love you…. Woojin…."
"…Don't call me Woojin. It doesn't suit you."
"S-shut up…."
And I started pleasantly pounding my cock between Lee Jiyoon's thighs.
