"Haah... haah... this is insane...!"
"Y-yeah, seriously..."
After the kiss time, my mind went completely blank and I have no idea how the game ended.
In front of all those spectators...
Real siblings kissing each other.
The thought of "what if our identities get exposed?" felt dangerous, but at the same time, that incredible thrill came as an enormous sense of transgression.
"O-oppa... what do we do now?"
"It's fine. We put our masks on quickly, right? They won't recognize us."
"Hi-hiing... y-yeah, right?"
Comforting the anxious Mihyun honestly I was pretty scared too but acted like it was fine while calming my pounding heart...
I suggested to Mihyun:
"Hey. You don't need to watch more baseball, right?"
"Huh? Why, why?"
"...I can't hold back anymore."
"..."
Honestly,
A girl who normally has no interest in baseball,
who took tons of Instagram photos here, ate lots of delicious food at the stadium, appeared on the kiss cam and received attention from thousands of people whether she wanted it or not...
She's done enough, right?
You can have your cake and eat it too... well, the eating part starts now.
Anyway, as expected...
She also brought her lips to my neck and whispered:
"...I'm also going crazy from being turned on. Let's hurry to the hotel, oppa."
"Right?"
Maybe it's because we're twins.
Mihyun and I were so in sync.
We whispered to each other, glanced around at the people nearby, hurried to the locker room, then rushed out of the stadium and headed to the hotel we'd reserved nearby.
=====
"We'd like a room."
"Ah, yes. What grade of room...?"
"How much is the most expensive one?"
"Whoa. Oppa, you have a lot of money?"
"Mom gave it to me."
"...Mom did?"
"Huh? Oh, I just said I was going on a date with my girlfriend and she gave me a lot of money."
"Mmm..."
Actually, I didn't say I was dating a girlfriend
I outright told her I was going to sleep at a hotel with Mihyun.
No, if I say it like that, it sounds like I'm trash for extorting Mom's money
Anyway, our mom...
She's basically like a small business now.
She's an America TV camgirl with an average of 2000 viewers.
Even after taxes and fees, she makes tens of millions of won just from star balloon income alone.
So her spending has gotten huge too.
And...
Mom seems to have kind of given up on our sibling relationship?
Now even when I openly tell her I'm having sex with Mihyun right in front of her,
she doesn't really try to stop us properly.
'Make sure to use protection. Got it?'
'Yeah Mom... but why are you giving me so much money?'
'Sigh. Don't stay at some shabby place. Stay somewhere expensive. W-women like that kind of thing...'
She even gave me a big allowance for the date with Mihyun.
When I think about it, it's kind of funny
Mom definitely started doing sexual things with me as an excuse(?) to receive my overflowing sexual desire instead of cutting off my relationship with Mihyun.
But now it's like she's completely forgotten the original purpose, and lately there's not even a mention of us not having sex.
Well,
even while training Mom,
I deliberately made her hear me having sex with Mihyun...
Maybe she just gave up?
Though she desperately begged us to use contraception, saying pregnancy was absolutely not allowed...
"Hey, you're taking the pill again, right?"
"Yeah. I've been taking it again since last week."
"Hehe. So I can go wild with creampies?"
"Ugh... so cheap. 'Can I go wild with creampies on my little sister?' You sound like a kid."
"You and I are the same age, dumbass."
Anyway, thanks to the allowance Mom gave us, we got the key to the top floor suite,
and while bickering like friends of the same age as we headed to the elevator,
we were both incredibly turned on from what happened at the stadium.
So when all the other couples who got in the elevator with us got off...
"Oppa... haah!"
"Today I'm going to completely strip you naked and devour you... be prepared."
The sexual desire that had built up for hours exploded...
I went crazy biting, sucking, and kissing Mihyun's lips in the elevator.
Slurp... sluuurp!!
Our lips touched,
our tongues tangled together.
Drinking Mihyun's sweet saliva...
Naturally, while our lips were locked, our hands weren't idle either, groping each other's bodies.
Of course, first I grabbed her incredibly big, soft, jelly-like breasts and kneaded them.
The size and texture that couldn't be hidden even through clothes got me newly excited, and my hands moved down below.
"Haah... haah... I'm so turned on, oppa..."
"Let me see... wow, you completely... came already?"
"I don't know..."
She happened to be wearing a short tennis skirt that came down just below her butt.
When I reached down, I immediately felt her panties...
They were incredibly sexy T-back string panties that you couldn't tell if they were underwear or just string scraps...
A pathetic dam that couldn't stop the love juice flowing from her pussy at all.
Just drip drip drip drip.
The inside of her thighs had become slick with wetness quite a sight.
Wow.
Really trying to turn other guys on...
"Fuck, you're so lewd. You came wearing these string scraps? Huh?"
"Hehe. To turn oppa on."
"Other guys saw it all too, damn."
"Why? Are you jealous? Hm?"
"Yeah. I'm jealous."
"You're always messing around with other girls but you get jealous of me? Hmph."
I have nothing to say to that.
Seeing my flinching expression, excited Mihyun starts teasing me more.
"What? Didn't you think about Sohye or that Yeonwoo bitch? Ah~ should I have sex with Habin too? He's so pitiful, hehe. He'd probably cum if I just held his hand."
"Stop being cheeky."
"Stop being cheeky~ what if I am? What are you going to do about it, oppa?"
Again...
Again...
The brazen girl deliberately provoking me, expecting punishment.
So,
as soon as we arrived in front of the top floor suite,
"Kyaak...!"
"You're dead today. I'll make your legs go completely weak."
"Hngh!"
With hands trembling from urgency, I hurriedly opened the door,
and right at the entrance grabbed her hair and dragged her.
"Ah! It hurts!"
"Come here!"
Mihyun acting like she was scared by my rough actions.
But wanting to make that fake acting real...
I deliberately dragged Mihyun to the window.
The top floor with a view of Hanbat Arboretum and Expo Bridge.
So even looking up from below, you probably couldn't see anything, but...
"O-oppa? W-wait a minute."
"Come here. I said I'd kill you, didn't I?"
After dragging her to the wide floor-to-ceiling window, I tore off the clothes of this cocky little sister.
Rip!!!
Pop pop pop!!!
The buttons that were already struggling because of her cow-like huge breasts all flew into the air and met their end.
"Ah?! Hey!"
"Be quiet!"
After roughly and violently literally tearing off her top, I grabbed her hair and pressed her face against the big glass window.
"Hnngh...!"
"It's because of you seductively swaying and tempting oppa all day!"
Smack!
And I also slapped her lewdly big ass once...
"Stick your ass out!"
"Haa... hngh!"
"Spread your legs!"
After making her stick her waist back for easy penetration,
I also pulled her tennis skirt up above her waist
and the incredibly lewd string panties...
Riiip!!
I tore them off with strong grip strength.
"Ugh...?! Ah, it hurts...!"
"It's supposed to hurt, so endure it."
Then, ptui!
After spitting on my fingers once,
Mihyun's cunning pink, plump pussy as she stuck her waist back like a bitch.
I shoved two spit-covered fingers into it at once...
Squelch
No,
There was no need to spit for lubrication at all.
"Wow. You're soaking wet like a total slut. Hey, can you hear this sound? Hm? The squelching sound of your pussy juice."
"I-I don't know... ugh!"
Slurp squish... squelch
An indescribable sound,
the kind of lewd sound that's half air, half liquid that only comes when pussy juice has filled more than half the vagina and is pooled inside that's what came from my little sister's pussy.
Naturally, Mihyun's lewd pussy juice pushed out by my fingers and flowing outside
Drip drip drop!
fell like a flood onto the hotel's expensive carpet, staining it.
"Haah... haah... Do you like wearing a perverted sexy bikini to seduce men and make oppa jealous? Hm?"
"Hngh... why, were you turned on?"
"Yeah. I wanted to gouge out the eyes of all the other men looking at you but I held back, you know? So you need to be punished, right?"
"Haaugh... s-stop..."
"Shut up. Bite down on this."
I forcibly shoved the string panties, soaked with Mihyun's sweat and pussy juice that I'd torn off her, into their owner's mouth...
Smack! Slap!
After hitting her ass and thighs hard once more, I couldn't hold back anymore and shoved my cock in.
"Haah... haah! Fuck, does it feel good eating your real brother's cock? Hm? Does it feel good?"
"Mmph... mph"
Nod nod.
That was her expression saying the cock tasted good.
Satisfied with that sight, I pressed Mihyun's entire body down with mine,
making her stick to the hotel's floor-to-ceiling window, then
"Hngh... hup!"
Slam!
Smack!
Slam!
I moved my hips...
Every time I pressed down, Mihyun's body stuck to the glass window,
and every time I pulled my hips back, Mihyun's body, especially her lower belly, would stick to the glass window then peel away with a smacking sound that turned me on.
Continuing like that
Bang bang bang bang!
Making drum-like sounds as I tormented Mihyun's pussy,
while simultaneously biting and sucking every protruding part of Mihyun's body with my mouth her nape, cheeks, ears...
"Ugh... haah... haah! It's too hard... ah!"
"Hard? Hm? Are you suffering while getting fucked by oppa?"
"Yeah! I feel like I'm going to cum too much, I can't hold back... ahh! Ah! Ah!"
Of course, for her it wasn't suffering but pleasure...
Or rather, she seemed to be suffering because the pleasure was too intense.
So she also made beast-like sounds while trembling all over.
"What do you think people would think if they saw from below? Hm? Hm?"
"Mph... haah... haah! I-I don't know!"
While also verbally humiliating her like this...
Maybe because she has strong M tendencies, she got more excited and clenched her pussy even tighter.
"Haah... haah... ah, I can't hold back..."
But,
because I'd already gotten so turned on at the stadium that I was almost going crazy...
even I couldn't last long.
So just as I was about to cum inside her pussy
"Hey... suck it up. Got it?"
"...Huh?"
A more fun idea occurred to me, so I pulled out my cock just before cumming
and stuck it between her thighs, using the smoothness of her thighs as a side dish to rub against.
"Wh-what are you doing?"
"W-wait and see... ngh!"
Spurt spurt spurt spurt!
I already ejaculate several times more than the average adult male...
When I released the sexual desire that had been concentrated for hours all at once
Spurt spurt spurt spurt spurt spurt spurt spurt!
Like pissing, semen shot out non-stop.
Of course, in front of Mihyun's body,
onto the glass window.
After cumming completely, I made the dazed Mihyun kneel and forcibly pulled her down to give her a 'punishment.'
"For being cheeky to oppa... you're going to clean the glass window. Got it?"
"Huh...?"
"My cum that I shot on this glass window. Lick it all up cleanly with your tongue."
She hesitated for a moment, but eventually started licking my semen that was stickily clinging to the glass window and slowly dripping down with her tongue.
And I,
went out to the terrace outside the glass window
and with a camera filmed my lewd little sister's face as she stuck out her long, thick tongue lewdly...
licking up the dirty cum stuck to the inner window as if it tasted good.
