Becoming the Doormat to Make My Unnies Get Along
I'd been planning to smooth things over between my unnies as quickly as possible.
"Hyahp…♡ Churuup…♡"
"Hngguup…♡ H-Hee-soo…♡"
"Come join us too, Ha-young…♡"
"Y-Yes… Unnie Hee-soo…♡"
How the hell did I end up striking sex poses while tangling my tongue all sticky with my unnies'?
"Churuup…♡ Hngup…♡"
"Haa…♡ Ha-young's tongue is always so delicious no matter when I taste it…♡"
It was all because of Unnie Hee-soo's insane tongue work.
Back when she'd first dragged me onto the bed, I'd been desperately trying to wriggle free.
Me sandwiched in the middle of their reconciliation sex? The setup was all kinds of weird.
But then Unnie Hee-soo blocked my lips as I tried to talk my way out.
She sucked everything in with loud smacking sounds, wrapping her tongue around mine like she was devouring it whole.
That flipped the doormat switch buried deep inside me.
"Th-This is our first time with three people…♡"
I grabbed Unnie Hee-soo's breasts, and soft flesh overflowed between my fingers.
"Whoa… Unnie's tits are so huge it's straight-up unfair…♡"
Touching Unnie Hee-soo's breasts felt like kneading soft, chewy dough.
They were such massive jugs that defying cup sizes, once you felt that texture, you couldn't stop groping.
"Smooch smooch, so huge…♡"
"Does our Ha-young want to suck on unnie's titties?"
Unnie Hee-soo was struggling to peel off her hoodie, her breasts getting caught in the process with little grunts.
I gave the hem a light tug to help, and her two tits bounced visibly into view, jiggling away.
From then on, those endlessly wobbling breasts looked just like pudding.
"Whoa… looks delicious…♡"
"Let's suck on unnie's titties."
I cupped them with both hands and lifted, drawn in like I was mesmerized.
That's when I snapped back to why I was even here.
Even if I'd stumbled into a surprise yuri threesome, the main event was supposed to be Unnies Hee-soo and Ye-na.
"Unnie Ye-na, come suck on Unnie Hee-soo's tits?"
"Eh?! M-Me…?"
Unnie Ye-na was totally flustered, unable to give a straight answer.
This was her first time in a setup like this, so even as the junior, I figured I should take the lead.
"Come here, unnie."
I gently took Unnie Ye-na's hand and positioned her face-to-face with Unnie Hee-soo.
Her eyes wandered lost, probably overwhelmed by those enormous tits.
"Let's get this off first!"
"W-Wait a sec… Ha-young…"
I stripped off her hoodie covering her upper body, and Unnie Ye-na hurriedly cupped her breasts with both hands.
Maybe because she was facing Unnie Hee-soo, she seemed self-conscious about her smaller chest.
"It's okay, unnie."
"But…"
"Really, it's fine. Unnie's breasts are pretty…♡"
"Mine are so small…"
Even with Unnie Hee-soo's gentle voice, Unnie Ye-na kept hiding her chest.
"Can't I see unnie's breasts?"
"Th-There's nothing to see…"
"Who says? Unnie's tits are so pretty. I love unnie's breasts…♡"
"R-Really…?"
After a moment's hesitation, she slowly pulled her hands away. Unnie Hee-soo immediately flicked her tongue tip against Unnie Ye-na's nipple.
"Hingyat…♡"
"I'll have a taste first, unnie…♡ Churuup…♡"
"Huuhyaaaang♥ H-Hee-soo…♡"
"Chururuup… Smoooch…♡"
"Hnghigiiik♥"
I'd expected Unnie Ye-na to finally give in and suck on Unnie Hee-soo's breasts after hesitating, but it was the opposite.
Unnie Hee-soo hugged her tight and lewdly suckled her tits, making Unnie Ye-na collapse back onto the bed, unable to endure it.
"Smoooochoo…♡"
"Hngyaaaaang♥ M-My tits are gonna get bigger♥"
"Pahaa…♡ Tits this tasty are against the rules, unnie…♡"
"Wh-What are you… saying…♡"
"Wanna suck mine too?"
The nipple at the center of those massive breasts poked and teased Unnie Ye-na's face.
"Gulp…"
I could clearly hear her swallow, then she tentatively parted her lips and engulfed the areola and nipple together.
"Huuhyaat…♡ Unnie Ye-na… you're so cute when you suck…♡"
I gently stroked Unnie Ye-na's head while starting to rub my pussy.
Watching the scene with my eyes wide open was insanely stimulating.
It felt taboo, like having the hottest masturbation side dish right in front of me.
-Squish! Squish!
"Hnghguut…♡"
In the end, I started cautiously rubbing my pussy while watching my unnies fuck.
I wanted to plunge my fingers in deep, but that might interrupt their time together.
"Hyahuuung♥"
I slid my upright fingers stickily along my slit, then flicked my clit.
Ever since seeing their sticky kiss, my body had been reacting—my clit was already nicely swollen.
"Haa… Hngguut…♡"
-Squiiiish!
"Huhubuuup♥"
I was focusing hard on stimulating my clit when Unnie Ye-na's moan echoed out.
Unnie Hee-soo had shoved two fingers deep into her pussy.
"Pahaa…♡ H-Hee-soo…♡"
"Unnie's pussy is squeezing so tight? My fingers are throbbing…♡"
"Th-That much…♡"
-Squiiiish!
"Hyahuguuk♥"
Unnie Hee-soo starting fingering made for an even hotter masturbation side dish.
With all those lewd sounds coming from Unnie Ye-na's pussy, I figured mine would get drowned out, so I shoved my fingers deep too.
"Hngguuuk♥"
Whenever Unnie Hee-soo pistoned fast into Unnie Ye-na's pussy, I sped up to match.
"H-Hee-soo…♡ I'm… Hngguuk…♡ Hnghiyaaaaang♥"
-Pshuuuuut!
How long had Unnie Hee-soo been thrusting into Unnie Ye-na's pussy?
A gushing sound roared out as a jet of fluid sprayed.
Unnie Ye-na had probably only masturbated until now, so her quick climax made sense.
"Hngiiik♥"
While Unnie Hee-soo watched Unnie Ye-na tremble and squirt, I stimulated my inner walls near my clit and my clit itself, racing to finish before they noticed me.
"Oh my, looks like there's a naughty little sister masturbating while watching her unnies fuck so sweetly?"
Just as I was about to cum, Unnie Hee-soo had snuck up close and was staring right at me.
"U-Unnie…?!"
"Unnie Ye-na, what should we do with this naughty dongsaeng?"
"Ung…?"
"Unnie… it's not masturbation. My pussy just itched here…"
-Squuuuish!
"Hihyahaaat♥"
Unnie Hee-soo casually crushed my pussy under her hand.
Since my fingers were already buried deep, they sank even further.
"Our Ha-young's telling lies now too?"
Unnie Hee-soo boldly slipped her hand into my pants.
To pull out the fingers lodged in my pussy.
"Whoa, look at all this soaked love juice. Dripping like crazy."
"Uuu…♡"
"Strip, Ha-young."
"Huh?"
"Hurry up. You gotta listen to unnie, right?"
"Uuut… Y-Yes…♡"
Unnie Hee-soo's gaze made it clear I had no choice.
I slowly stripped, then lay back on the bed at her guiding touch.
"Spread your legs, Ha-young."
"Y-Yes…♡"
Once again, I obediently parted my thighs.
"Unnie Ye-na, keep an eye on Ha-young for me."
"U-Ung… Got it…♡"
What the hell was she planning that she even called over the panting Unnie Ye-na?
"Look how pervy our Ha-young is. Churuup…♡"
"Hnggiiiik♥"
I figured she'd start by licking or fingering my pussy at most. But right away, she plunged her tongue deep into my asshole.
"W-Wait… U-Unnieee♥"
Her tongue writhed skillfully, slickly lapping my inner walls—it was only natural for my body to tremble like I was convulsing.
"H-Ha-young… you feel it from there too…?"
Unnie Ye-na watched me with a deeply flustered voice.
"I-It's not feeling good…♡"
"Smoooochoo…♡"
"Hnggoooooook♥"
Just as I tried denying it, Unnie Hee-soo sealed her lips around my asshole and sucked.
Spitting out such beastly moans in front of Unnie Ye-na was mortifying.
"Hnghyaaaaat♥ H-Hee-soo unnie… st-stop with the ass… Hehngguuk♥"
She knew my body too well to let me hold back the sensations.
"Y-You feel it from there too, huh…"
Unnie Ye-na sounded amazed, like she'd witnessed something unbelievable.
"N-Nooooot♥"
Now I got it.
My punishment for jerking off to my unnies' sex was showing this humiliating side in front of Unnie Ye-na.
"Smoooochoo…♡ Churuuup…♡"
"Hngyaaaaang♥"

-Pshuuuuut!
Her rimming—sucking my asshole while tonguing my rectum—pushed me over the edge.
Every time Unnie Hee-soo pressed her tongue tip against the upper wall, indirectly stimulating my pussy, short spurts of fluid jetted out—pshut psht!
"Hngyaat…♡ St-Stop… H-Hee-soo unnie…♡ Hnghigiiik♥"
"Pahaa…♡ Ha-young's ass-pussy was delicious♡"
Only when the squirting finally stopped did Unnie Hee-soo's tongue withdraw from my ass.
"D-Does it normally feel good there? Or… is Ha-young special…?"
"You can train it to feel good."
"Train it…?"
"Yeah, I trained our Ha-young. Right, Ha-young?"
"Y-Yesss…♡"
Unnie Hee-soo's rimjob technique was pure ecstasy no matter when she did it.
Just looking at her face made my asshole twitch.
"Um… Ha-young…"
"Yes…?"
Unnie Ye-na approached slowly, thighs clenched together.
"Lick my pussy…"
"Huh…?"
"Watching you and Hee-soo… I can't hold back again…♡"
"So I'll lick unnie's pussy— Mmph!"
I tried confirming if I'd heard right, but Unnie Ye-na slammed her pussy down on my face.
My face instantly grew slick, hit with hot heat and the musky scent of her juices.
"Unnie Ye-na, Ha-young's pussy-licking is amazing."
"Really…?"
"Yeah, you'll feel incredible. Wanna kiss?"
"Ung… Let's kiss… Hee-soo…♡"
"Churuup…♡"
"Hngbup…♡ Churuup…♡"
As Unnies Hee-soo and Ye-na dove back into their kiss, the pussy pressing my face began grinding slowly back and forth.
"Hubuuup…♡"
Their relationship seemed fully back to normal now.
No—definitely deeper than before, incomparable.
This was a great thing.
So why did it feel like I'd become the tool used to fix their bond?
