The Accomplice and the Sister
…I know Woojin was feeling good, too.
I mean, I was just pressed underneath you, being used like some… well, like a bed. How could I not know?
Seo Woojin, you started off moving slowly, as if you were being careful of me. But the moment Jiyoon bit my shoulder, you started thrusting faster, didn't you?
At first, all I could hear were the wet, squelching sounds of our fluids, but at some point, there were these loud, slapping sounds—thwack, thwack—as you buried yourself to the hilt.
And when she started licking you so tenderly… it felt even more intense than when you’re with me….
"…."
…Ah, seriously.
What is this, because of Jiyoon?
Could it be that you actually felt better with her than with me?
Is that why you… ejaculated so much?
I keep having thoughts like that.
I really, really hate it.
Woojin, the one actually involved, told me that he liked it much, much more with me. He even had sex with me right before this, as if to show you, to make sure you wouldn't try to crawl into our relationship.
…Haa.
Stop trying to stir up trouble between us, Lee Jiyoon.
Do you really think I’d break up with him just because of that? Not a chance.
"Huu…."
Jiyoon never listened to me when we were younger. Was that because she hated me?
That doesn't make sense; we never had any major fights. Just things like, "Stop playing games so much, you'll ruin your eyes," that sort of thing.
So, does she really like Woojin that much?
…No, he’s my boyfriend.
Can’t she find someone else to like? Seriously….
There have to be some handsome guys in the first year, right?
Of course, I’ve never seen anyone better than Woojin on my way to school….
I groaned, watching Jiyoon walk into her room so carefree, unlike me. But after a moment, I put a white towel over my head and headed to the kitchen.
…Maybe it’s because I’ve been so worked up since earlier.
I was just so thirsty.
"…."
But maybe it was because I cooled down with a glass of cold water? The wicked voice of Jiyoon that I’d heard in the bathroom started replaying in my brain.
Asking if it was disgusting to have her shoulder bitten and licked. Saying that even if she hated it, there were plenty of perverts among men who liked that kind of thing. And that insane, crazy suggestion that we should face each other and lick… lick Woojin’s cock together.
Honestly, if you just look at that, it wasn't a huge problem. I could have just brushed it off, thinking, "Sigh, who does she take after, being such a pervert?"
But a small problem arose because of the thoughts that started creeping in afterward.
…Which is.
"…Ugh."
The more I chewed on it, the more I realized that Jiyoon’s argument had a certain persuasive power that was hard to ignore.
"…."
Look, right?
If you look at adult sites, there are plenty of videos with two women and one man having sex, right? In the end, those are popular, so people film and upload them a lot.
And if you add the fact that Woojin had a slightly perverted side, like how he liked it when I called him "Oppa"….
I sighed, nibbling on the edge of my cup with my lips.
"…Is that stuff actually that good…?"
I’d refused earlier because I was annoyed and it felt wrong, but… the way Woojin looked, so incredibly excited, gripping Jiyoon’s pelvis and thrusting into her… or the results of his ejaculation that I saw with my own eyes, flowing out….
Because of things like that, it didn't feel like she was entirely wrong.
Of course, that doesn't mean Jiyoon’s body is more compatible with Woojin than mine is…!
It just means that maybe he was excited because he saw Jiyoon doing weird things to me, right?
The timing was perfect, too. Jiyoon isn't the type to do that, but she suddenly started doing weird things to me. And from her perspective, she could feel Woojin’s excitement directly inside her, so it felt like she did it on purpose to try and beat me….
"Ugh…!"
I don't know, I don't know.
Maybe that’s one of Woojin’s preferences. I’ll admit that much.
But that doesn't mean I want to do it.
It’s not for any complicated reason.
It’s just weird for sisters to do that, isn't it?
It’s weird for me to be in that kind of atmosphere with you, Jiyoon.
…It’s incredibly embarrassing.
Asking how it would be if we licked his cock while facing each other, or saying that kissing his body should be fine….
…Ugh.
Just imagining it makes me want to throw up….
Clatter. As I set the water cup down in the sink, I heard the faint sound of a hair dryer starting up in Jiyoon’s room.
I glared at the door with a pout, shook my head, and headed to my own room.
A thought suddenly occurred to me: maybe she had come up with another pathetic scheme to have sex with Woojin again.
Well, it was hard to be certain, especially since the fact that Woojin had been quite excited still remained.
When I opened the door, Woojin was sitting on the bed in his pajamas, looking at me with a complicated expression, as if the excitement from the living room had cooled down.
In common parlance, he had a look that said, "I'm screwed."
There was a hint of a desire to smile, since I was in front of him.
And there was also a late-breaking brake in his expression that said, "I shouldn't be smiling in this situation."
Well, even if there were circumstances, he had ejaculated inside his girlfriend’s younger sister right in front of his girlfriend, so it was only natural for him to react that way.
But I think… Jiyoon, who is acting so shameless, should be the one apologizing to me more.
"…."
I didn't think for long.
Before Woojin’s expression could sink any further, I gave him a bright smile, and only then did a faint, relieved smile appear on his face.
…Was that a bit like a big sister…?
"Woojin-ah. We’ve both washed up, so you go wash up now, too."
"…Ah, um. I was going to dry your hair for you before I went to wash up."
"Why not just go wash up now? I’m better at drying my hair than you are."
"…I feel like I need to… apologize."
"…."
It was something I could have guessed from the atmosphere earlier.
After looking up at his face for a moment, I hugged him tightly and headed to the bed together.
It wasn't because I wanted to do something lewd as soon as we came out of the shower.
It’s just….
There’s no grand reason.
It’s just that his sweaty body probably had Jiyoon’s scent all over it, too.
And I was a little… jealous of that.
I just wanted to leave my scent all over him, at least until he went to wash up.
"Noona, I haven't grabbed the hair dryer yet…."
Even though he could have resisted, he stepped back as I moved, and I pushed him down onto the bed and sat between his legs.
"There’s a towel. A towel."
I pointed at the towel on my head.
"The hair dryer is too loud, so we won't be able to hear each other talk… so let’s start with this."
Wearing only my underwear.
Tightly, hugging him.
I acted spoiled.
"You have to tell me if it hurts, okay?"
"It’s just drying my hair with a towel, what could possibly…."
He seemed so cautious, so I playfully rubbed my wet hair against his body and smiled as if it were nothing.
I realized a bit late that my freshly washed hair had gotten a little dirty, but… it’s fine. It’s no big deal.
And then, we talked, one by one, through his boyish hands that were trying so hard to be gentle.
"…About, um, what I did inside…."
"Forget it, forget it. It was safe, and it was an accident. It would be different if you’d done it on purpose, but it just happened because it tore."
"…."
"And Jiyoon, too… you should have stopped her if you thought it was weird, but you were so excited… sigh…."
You did something wrong, but!
It wasn't just your fault.
Lee Jiyoon, that crazy bitch, was basically an accomplice and the mastermind, so how could I blame just you?
"…."
Besides,
I had a share of the blame too… for having sex in front of Jiyoon just because I thought it would feel good, right?
If Jiyoon is 80% responsible,
You’re 10%.
And I’m 10%.
Something like that.
"So it’s okay. I’ll let it slide just this once. Don't do it again, okay?"
"…Yes?"
"Hmm? Why are you asking me back? Did I say something weird?"
"The… 'Don't do it again' part."
"…O-oh, just in case something similar happens again…! Just in case…. Yeah. Just in case."
"Aha. Just in case…."
Having finished my rambling forgiveness and explanation, I hugged Woojin, who had returned from his shower, and drifted off into dreamland.
Part of me wanted to have sex all night, but shouldn't Woojin get some rest, too? Besides, it’s not like today is the end; we have two more days left, so there will be plenty of opportunities.
If I can make Jiyoon give up on Woojin completely during that time….
….
…And while I’m at it,
If I can have sex with him like I’m showing off to Jiyoon again….
"……Nng…."
…Maybe it’s because it’s been a while since I slept with someone, but I think I had a very lewd dream.
I don't know the details, but it felt much more cramped than usual.
I figured it was just because Woojin was sleeping next to me.
Since it was just a dream, it didn't stay in my memory for long.
*****
Just as Jiyoon said, Lee Hayoon was the type who wouldn't wake up even if you carried her away once she fell asleep.
Still, she had to rub her face against my chest while she slept, so I thought she might wake up if I tossed and turned, but no.
When I just tucked the blanket I was using into her arms, she just hugged it happily and rubbed her face against it.
After pulling on Lee Hayoon’s cheeks a few times like dough to check, I caught my breath and slipped out of the bedroom.
The place I arrived at was,
Naturally, where the "accomplice" was.
"Don't you think it’s dangerous to call me out like this on KakaoTalk? What if your sister saw?"
"Then how else am I supposed to call you? Should we make up a secret code?"
"…Haa…."
"Anyway, how did my sister react? She seemed a little interested in the bathroom."
Lee Jiyoon.
The girl who wants to have sex with me in front of her own sister.
She pulled up her pitch-black sleep mask and smirked.
…Well,
Of course, she wasn't actually wearing it to sleep.
It seemed like she was wearing it just in case, listening for footsteps.
"She didn't say much. It was a bit awkward for me to bring it up first, too."
"…Really? That’s strange. I was 100% sure she’d ask me about it. Like, 'Did it feel good with Jiyoon?' or something like that."
"There was nothing like that… oh, she did say it was fine that I ejaculated inside."
"What is she talking about? Isn't that for me to decide? Why is my sister forgiving you?"
"It doesn't matter whether you forgive me or not anyway."
"…It does matter, though?"
The indifferent answer I gave while sitting on the edge of the bed.
Lee Jiyoon, who seemed to enjoy this secret meeting, smiled and reached out her hand to me.
"Since you’ve been forgiven… want to do it again? …Inside?"
Until the wrist she was holding slipped under the blanket.
"Why aren't you answering? My sister even proved that I’m on my safe days."
"…I was just wondering what you would have done if she hadn't forgiven me."
Until it slipped inside her pajamas.
"What do you mean, what would I have done? I was going to do it anyway."
"For what reason?"
"Do you really have to think about reasons to do that? …Heh. You don't look like it, but you’re such a nerd."
"…."
"Ah, there are a lot of people like that when you play games. It’s a total nerd culture, after all."
"…Come to think of it, why aren't you playing games? Isn't it time for you to be playing hard?"
"Why would I do that when something more fun has come up? Those are all just pieces of data anyway."
"…."
"…."
"…."
"Seo Woojin. Did you know?"
"What."
"My sister sleeps until 9 on weekends."
"…."
"…She’ll be even more tired today, so maybe she’ll sleep even longer than that?"
Until it slipped inside her underwear.
"You smell like our body wash… it’s… fascinating."
To that crazy bitch.
The sneer that I’m a real pervert.
The whisper that even if I do it harder, my sister won't wake up.
The panting that the wet wipes are over there.
The obvious temptation to wash up together.
Until I hear it all.
