…Having sex with Unnie’s boyfriend right in front of Unnie.

Even just that was thrilling enough to make my hair stand on end.

But I wasn’t satisfied with just that bad deed,

This time, I went a step further.

“Ah, caught.”

Even dragging Unnie’s really close friend into this bedroom.

And seeing Unnie’s boyfriend begging like this to Unnie’s friend.

It’s not bad, actually.

That much volume, I only saw when I first secretly had sex with Seo Woojin behind Unnie’s back.

“St-stop touching him…! Why do you keep touching my boyfriend’s body…?”

“Huh? He’s Unnie’s boyfriend, what’s wrong with it…? Is it that weird…?”

“It’s weird, so quickly take your hands off…! You can do that to your own boyfriend later, why Woojin…?”

“Alright, alright. …I just lightly ran my hand over his dick, why are you so sensitive…?”

“How is that ‘just’…!”

“It is ‘just.’ How is this different from a massage…?”

“It’s different…!”

Wow, I’ve never heard Unnie speak that loudly at this hour.

I wonder if the neighbors can hear it all, but since they aren’t complaining about the noise, I guess it’s a rare occurrence so they’ll put up with it for a day.

The neighbor… I remember him as an ordinary-looking man.

Maybe he’s busy masturbating to this noise, so he’s not saying anything.

…Ah, maybe it’s a bit much to slander someone else like that?

Smiling faintly with a bit of lingering drunkenness, I gently place my hand on Seo Woojin’s firm thigh.

In truth, it was an intentional act, but to Unnie who’s watching me now, I’ll just seem like a completely drunk idiot.

And as expected, Unnie’s cheeks will redden with jealousy and she’ll slowly wriggle closer like that.

“Woojin, over there…”

“…Ah, yes.”

“……”

Leaving Unnie, who adorably trailed off her words instead of saying ‘fuck me quickly’, alone.

I lightly bring my breast against Seo Woojin’s upper arm right next to me.

Even if it’s not as pretty and big as Dabin Sunbae’s breasts.

At least it’s slightly bigger than my Unnie’s.

…And men like big breasts, that’s basic common sense.

“Hey. Seo Woojin, you have to cum more for my Unnie than for Sunbae, okay? You know that, right?”

“…I know.”

“I’ll take into account that it’s your second time… but if the condom you used with Dabin Sunbae is way heavier…?”

It’s a lie.

I hope the condom with Dabin Sunbae was heavier.

I hope sex with Unnie’s friend felt better than sex with Unnie.

I hope having affair sex with the younger sister felt better than sex with Unnie.

…And always, from now on, secretly, behind Unnie’s back.

So I can continue my bad deeds.

I hope Unnie’s pussy is subtly not that great.

Just a tiny bit, though, so the toy doesn’t break.

Just enough to make me think I might be able to beat me or Sunbae.

“That won’t happen. …It might be similar, though.”

“Is that so? From what I see, you’ve already ejaculated once, so it seems like it’ll be hard~… You usually….”

“Wo-Woojin. Jiyoon seems drunk, so just let her babble on her own…”

So,

The back of this naughty guy,

Who is about to aggressively screw my Unnie on the bed.

Despite being his girlfriend’s younger sister.

I silently embrace him lightly.

My breasts, which had just been rubbing against his forearm,

Now press firmly against Seo Woojin’s back.

This way, the stimulated Seo Woojin will be able to ejaculate more.

And only then can Unnie even hope to keep up with Dabin Sunbae.

I’m giving her an advantage directly.

It’s definitely not because I want to, but an advantage.

…See? If Unnie looks at my arm wrapped around Seo Woojin’s waist, she’ll know exactly what I’m doing.

But she’s quiet instead of telling me to stop, right?

“Alright. I’ll just keep babbling by myself… so just cum all over Unnie’s pussy.”

“……”

“You’re good at that, aren’t you? Ejaculating as if you’re trying to impregnate someone.”

“……”

Even though I whispered, fragments of the words must have reached Unnie’s ears.

But instead of getting angry, she merely blushes and waits for Seo Woojin.

“…Alright. Shall I help you spread Unnie’s pussy…?”

Pressed close to Seo Woojin’s back, rubbing my breasts against him.

With one hand, I carefully spread Unnie’s pussy, as she clamps her mouth shut, about to say something to me.

…Wet with vaginal fluid because this pervert licked her.

Into the beautiful colored inner vaginal wall.

“……Ugh…, …Haah……”

I push in her boyfriend’s dick.

…Well, to be precise.

Instead of saying ‘boyfriend,’ I should use the term ‘cheater.’

Personally, I feel that specifically calling him ‘boyfriend’ is a bit more arousing.

Doesn’t everyone feel that way?

Rather than having sex with a simple cheater,

Having sex with Unnie’s boyfriend is more arousing, right?

…Even Dabin Sunbae, who is quietly watching right next to us.

Rather than just sharing intimacy with a simple cheater,

It would be a little more arousing if he were her friend’s boyfriend.

“Ha…ah……, today…, it feels a little more….”

“Bigger?”

“…Lee Jiyoon, you be quiet…, ugh, just be quiet….”

Ah, perhaps it’s uncomfortable for him to move if I’m too close behind him.

Thinking that, I moved slightly to the side again, and the splashing sounds became a little more explicit.

Seeing their hands tightly intertwined in this situation, and especially seeing Unnie’s fingers clench, she must really be enjoying it.

Usually, she’s busy sweetly moaning when Seo Woojin ‘uses’ her aggressively, but now that she’s experiencing it, she seems to like this slow-paced sex too.

But what a pity.

“Be quiet? I’m helping Unnie, you know?”

“No need…. I said no… hah……. I might say something wrong, so just… stay still….”

“Wait a moment?”

“Ugh, ugh, ugh…, you’re usually just busy playing games…”

If you ask if he can extract as much cum as Dabin Sunbae with this kind of sex.

I definitely think it’s impossible.

“Don’t men like this kind of thing…?”

For a brief moment, letting Unnie’s annoyance pass through one ear.

I kneel beside Seo Woojin and lightly bite his ear, which is right in front of my eyes.

I also blow air playfully to make him pay attention to me.

But something feels a little lacking.

It felt good when I was on the receiving end, but when I’m on the giving end, I’m not so sure.

Still, seeing Seo Woojin pressing his hips more than before, it seems to be somewhat effective.

Moreover, Unnie’s gaze directed at me,

…It’s already so blurry.

“Ah, you like this? When you’re having sex with your girlfriend, and your girlfriend’s younger sister bites your ear?”

“Woojin……ah…, wait…, that, it’s really pressing down….”

The more I stimulate Seo Woojin’s eardrum.

The louder the stimulating sounds of sex, *thump, thump*, from below continue to get.

“…But this also feels a bit like cheating, doesn’t it… hmm…”

“……Ugh, not there…, not there…”

The more I deliberately stimulate the fact that he’s cheating.

The more irregular Unnie’s panting breath from below becomes.

“You’re a real pervert. Right, Dabin Sunbae?”

“W-well…”

“What’s per…verted…. You’re much more… persistently staying here even though I told you to leave…”

“Oh, Sunbae, would you like to join us?”

“…Me?”

“Lee Jiyoon…! Stop talking crazy drunk nonsense… and get out… already…”

“Why? Haven’t you already done something like this with Sunbae? Haven’t you done it yet?”

“Well…. …Ugh……”

“As I thought, you have~”

Putting aside the pretext of ‘who can squeeze out more cum’.

Another woman who is interested in Unnie’s boyfriend, like me.

Calling her here.

“Sunbae, you should try it too. While Seo Woojin is screwing our Unnie like this, his ear or… Also, this is an erogenous zone for both men and women, they say… like this…”

Seo Woojin’s subtly prominent erogenous zone.

…Like when I was deeply immersed in self-pleasure.

I carefully touch it with my fingers.

And using my tongue, *slurp, slurp*, I lick it, looking up at his face.

“…It tickles, so don’t do it. It’s no good. That.”

“…Pffft…, really? Then~…. Hmm…. Shall I give you some side dishes?”

“…Side dishes?”

“Yeah. What you like.”

“…What is it?”

“First, can you give me your hand?”

After hearing that it was no good.

I naturally took one of his hands, which had been busy sweetly intertwined with Unnie’s, towards Sunbae and myself.

“How is it? It’s what you like, right?”

When the constant splashing sounds subsided a little.

These long, thick fingers, completely different from mine.

I guide them inside the jet-black knit sweater Dabin Sunbae is wearing.

Lightly passing over her smooth skin, up to the soft mound.

To the heavy milk mounds that feel as if there’s no bra.

To the already hard, cherry blossom-colored erogenous zones.

I tried to pull Sunbae’s smooth knit sweater, making it wrinkle unevenly, but.

“Honestly, it is what I like. …Wait a moment.”

“……”

…I failed.

“…Oh, …ugh……. Hey, Woojin…ah……. Suddenly it’s a bit…. Fas…ter….”

“…I’m sorry. I feel like I’m about to ejaculate.”

“If that’s… the case…, ……yes. …You can use my body… however you like….”

Seeing him diligently thrusting his dick, *slam, slam*,

While ignoring Dabin Sunbae’s overtly sexy breasts, and instead sweetly intertwining his fingers with my Unnie’s.

…As if it were pure love sex.

It seems he still wants to look good to Unnie?

Or does he have another plan of his own?

“……Oh, Jiyoon…, why suddenly….”

“Just a moment, Sunbae.”

“…?! Hey, wait…”

…Idiot.

If I just hug Dabin Sunbae from behind and pull this soft knit sweater up over her breasts.

And instead of you, I gather Dabin Sunbae’s breasts with my hands, boasting their soft elasticity.

And just pinch and twist the nipples that are tense from being screwed by you, like this.

Naturally.

Not Unnie,

But towards us.

His gaze can’t help but turn, right?

“…I love, you…. I love you……. Woojin, I like youuu….”

“……”

“…Ugh, phew…. Phew…, *kiss*…”

…Even if you, who saw this scene, belatedly frantically thrust your dick while pressing against Unnie.

Even if you didn’t even glance at us and mixed tongues with Unnie while vigorously thrusting your dick.

Even as you pant roughly,

And stick your dick deep inside Unnie,

And your scrotum twitches multiple times.

“…Blargh…. Heh……. Heh…*♡*….”

You’ve already seen it.

…And in the cum you’re now frantically pouring into Unnie.

Our share, mine and Sunbae’s.

Will be in there, I suppose.

“…You cum a lot again…. It really was because it built up during the day, wasn’t it….”

“…I told you it was.”

“My body must feel really good too…. Hehehe…”

That’s why I can say these words.

I don’t really know your original plan, Seo Woojin, but….

“What? A draw…? How boring…”

“W-why are you looking for entertainment in this…!”

“I thought it would be fun if Sunbae’s body felt better than Unnie’s, that’s why.”

“…It’s not funny at all.”

“But there’s a somewhat ambiguous part…”

“…What?”

Rather than your plan, like this.

Pretending to still be drunk, even though the drunkenness has almost worn off.

“Sunbae and I helped you ejaculate more from the side, but it’s still similar, right?”

“That’s…”

“…So, shall we try again? But let’s change the rules.”

“…You want to do it again? That… thing?”

“I said we’d change the rules.”

Thus, pretending to have a knack for only picking out irritating words.

“I think the most accurate way would be for Unnie and Sunbae to take turns inserting at the same time. …Then you’ll immediately know what feels better from Seo Woojin’s perspective, right?”

“…Hey, you crazy…”

“Why? Unnie is already used to doing it with three people…”

“Wait, wait, wait…. You’re very drunk, so stop saying strange things….”

“…Huh? You said Dabin Sunbae is your sex partner, right? You’re not used to it…?”

“Th-that’s true, but…”

“Then just inserting it one more time shouldn’t be a problem. Even if it doesn’t go all the way to sex. …Right?”

“……”

“Right?”

“……”

Subtly bringing up the topic.

This looks much cleaner.

…You pervert.
