Eun-ae's Anal Phone Call to Her Brother

"Ah! Min-jun oppa! Over here~!"

I spotted Eun-ae's face peering out from the window of a car parked across the street. I crossed the road and slid into the back seat next to her.

"Heehee. Long time no see, oppa!"

"It's been less than two days."

"That's forever! Hee..."

Eun-ae leaned against me. Her lover and brother sat in the driver's seat, stealing glances at her, but she didn't spare him a single look.

"Oppa! So, where are we going?"

"Hmm..."

I wrapped my arm around her waist.

"Anywhere Eun-ae wants to go?"

"Um... nowhere in particular... mo-motel maybe..?"

She stuttered it out, clearly embarrassed to suggest it first.

"......"

The guy in the driver's seat—basically her boyfriend—didn't say a word.

"Want to do it right now?"

My hand stroked her waist, then slipped between her legs.

"Eung... that's embarrassing... A-anyway, to the motel. Got it?!"

"Sure, sure, motel for some sex. Hey, Eun-ae's brother? Motel, please."

"..Yes.."

He started driving quietly. Kissing sounds came from the back seat, followed by his beloved little sister's moans and slurping noises... but he said nothing. At the stoplight, he just glanced at her in the mirror to feed his desires.

"Smack... mmm... smack.... slurp..! Mmph?! ....gulp.. gulp.."

Right before I came, I grabbed her head and pressed it down hard. She tried to pull away for a second but relaxed and swallowed my load.

"Hoo... ugh... warn a girl next time... jeez.."

Eun-ae pouted cutely. Even with her boyfriend driving up front, she had no hesitation sucking another guy's dick, swallowing his cum, and acting all aegyo. No guilt either. It was just natural.

Min-jun-ssi called it cheating sex, so that's what it was. If he hadn't said that, it'd just be fulfilling a duty.

That's how Eun-ae saw it.

"Heh, sorry. You sucked like a pro, Eun-ae."

"Ah.. yeah... b-before, with my brother.."

"I know. No need to explain, don't get down. You're mine now."

"..! Yes!!"

Unlike Eun-ae, who lit up with joy at my words, the guy in the front flinched and grimaced slightly. Yet his crotch stayed bulging—he was a true NTR masochist.

We arrived at the motel, and Eun-ae and I got out.

"Oppa, I'll be back? Wait here. I'll cheat plenty like you want♡."

"...Okay."

He bowed his head. He didn't want to show his face twisted in betrayal, humiliation, and arousal.

Eun-ae and I rented a room at random and went in.

"I'll wash up first♡?"

"Nah, let's just do it. Can't hold back."

I picked her up and tossed her gently onto the fluffy bed.

"Kyaaang♡."

She let out a playful scream, landed on the bed, and struck a defenseless pose while gazing at me.

"Min-jun oppa.."

"Eun-ae.."

We stared at each other like lovers. I didn't really love her, but it felt right. Made the stealing feel better.

I climbed onto the bed, approached her, and kissed the girl who had an owner.

"Mmm. Chu... chuu... mm.."

The man who'd cared for her all her life—her boyfriend and real brother—wasn't kissing her; some other guy was, and she accepted it gladly. I slipped my tongue into her mouth. She welcomed it, tangling her tongue with mine. Naturally, my saliva flowed into her, and she swallowed it eagerly.

No guilt at all for taking another man's—not her boyfriend's—tongue and spit.

Just like that, she let a stranger strip her without resistance, and soon her whole body was groped. Breasts, ass, thighs, belly—every part touched by an outsider. And now, she started servicing his cock.

"Hoo.. feel good..?"

Schlick schlick. Right now, she was thigh-fucking me like I'd done to Mom at the sink last time. Thighs and pussy lips caressing me—pure magic.

"You ever do this for your brother?"

"Ah.. nooo... with oppa.. never.."

"Oh? Just vanilla sex?"

"..He.. he wanted to, but I refused.."

A play she wouldn't do for her brother of over 20 years, she did for me after less than a week. Good girl.

"Why?"

"J-just embarrassed... too slutty, didn't like it.."

"But you were gonna cheat?"

She'd admitted wanting to cheat when we first met.

"Eut..! Th-that was..."

"That was?"

"..Ugh... so mean.. punishment! Cum nicely~!"

She sped up the thighjob. Schlick schlick—the lewd sounds deepened, pleasure intensified. Her soft thighs and labia stroked me, clit teasing deliciously.

Squish. The conquest—no, betrayal thrill—of another man's girlfriend grinding her pussy on me. I came from the excitement, spurting across my stomach and her pussy.

"Heehee.. feel good?"

"Yeah. You're good, Eun-ae."

I hugged her and stroked her hair. She smiled happily.

Then I aimed my cock at her asshole... and thrust all the way in.

"Hnnngh♡?!"

Root-deep, the tip hit a barrier.

"Hnn..♡ haa.. oppa.. sudden.."

"But it felt good, right?"

"Hee... yes♡"

"Me too."

Anal felt different from pussy—fresh pleasure. Missionary position, I slowly pulled ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠back.

"Hk.♡ hngk..♡"

Her intestines clung, begging my cock to ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠stay. Schlorp—lube and precum mixed into lewd sounds. She instinctively clenched and spasmed, sending jolts through my dick.

I leaned forward. Guessing my intent, she offered her mouth. Our lips met, devouring each other. Mouths wide like swallowing lips, tongues twisting to taste.

Sharing spit, connecting. With another man, despite having a boyfriend.

Meanwhile, I rocked my hips slowly. Schlorp—lewd sounds filled the room, pleasure building.

"Hnn...♡"

She spasmed and clenched once—I couldn't hold back and creampied her ass.

"Hk.. hee... heehee..♡"

Feeling the cum flood her guts, she grinned foolishly. Way bigger, thicker, more cum than her brother. Should've given her anal virginity to this guy. Shouldn't have gone with bro. Regrets like that, but she shook her head to clear them.

What am I thinking..!

She loved her brother. This sex was for ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠him... and a tiny bit for her own desires. Min-jun was helping with that.

Thinking that, she noticed me picking up her phone—hers, specifically.

"Eun-ae. What if I showed this to your brother? He'd love it, right?"

"Ah~!"

Yeah, duh. Not just telling him she cheated, but showing live—he'd love it more.

Oppa Min-jun really is..!

A cupid strengthening her and her brother's bond. With my cock still in her ass, she unlocked the phone and called her brother.

Ring ring.

-Yeah. Eun-ae? D-done..?

"Hnn...♡ Oppa..♡"

-Uh.. yeah?! What's wrong..?

He sounded thrilled at her sultry voice.

"Eun-ae. Like last time... anal pain is pleasure, got it?"

"..Yes..♡"

-Eun-ae?

Schlorp!

"Hnnnght♡!! Hk! Haaa..♡!!"

-Uh.. Eun-ae..?!

"Hnnk..♡ hnnngk..♡ haaaak..♡!!"

-....

I pounded her ass roughly. Pulling out to the tip then slamming root-deep, or side-thrusting.

"Hnnk..♡♡ haaang..♡ haaak..♡!!"

Each thrust made her squirt from her pussy, cumming repeatedly. One stab, one orgasm. She clenched hard in climax, making me creampie her.

It kept going. Thrust, cum. Pound, orgasm.

"Hnnnaaang♡♡ haaaang♡!!"

-....

No more voice from the phone—just flesh slapping.

-Ugh.. Eun-ae..!

"Haaaak♡♡ Oppa haa♡! Cumming again..! Hnggght♡♡"

-Eun-ae..!

I ravaged her ass relentlessly. Missionary to doggy. In doggy, slapping her ass made her clench hard—"Hnnnght♡"—pure bliss. I groped her swinging tits and ass.

Final position: mating press. I hammered her asshole vertically, using it fully. She didn't resist, letting me use her body—just like her boyfriend and family member did.

After an hour of sex, Eun-ae hit her limit. Endless orgasms drained her stamina and fluids—any more and she'd be in danger.

Didn't want to break a well-trained fucktoy, so I gave her water and let her rest. The call stayed connected.

I picked up the phone. "Thanks for the meal~."

While she recovered, I played with her body. If my family had firm, soft skin, hers was baby-smooth. Even light groping left handprints on her tits and ass.

Playing like that, I hugged her, savoring her skin and warmth against me, and checked my phone.

Su-a had messaged me. About an hour ago, right when I was fucking Eun-ae—missed it.

Sorry. Was fucking a girl I know.

Read immediately, reply flew in.
