My best friend Minjun and I had been close since college. We partied together, played video games, and shared everything — except one thing.
His younger sister, Ji-eun.
Ji-eun was 21, a stunning Korean girl with long black hair, smooth porcelain skin, and a body that made my cock twitch every time I saw her. She had perky C-cup tits, a tiny waist, and a round, firm ass that looked incredible in tight jeans. She had that classic “innocent idol” face but moved like she knew exactly how hot she was.
For two years I tried to hide how badly I wanted to fuck her.
One weekend, Minjun told me he was going to a big house party. What he didn’t know was that Ji-eun was throwing her own party at their parents’ huge house while they were away.
She texted me privately:
Ji-eun: Oppa… come to my party tonight. Minjun isn’t invited 😉
I knew I shouldn’t. But I went anyway.
When I arrived, the house was already wild — dim lights, loud music, and about 25 people. Most of them were already half-drunk and making out. Ji-eun greeted me at the door wearing a tiny black crop top and a short plaid skirt that barely covered her ass.
“You came,” she smiled, biting her lip.
The sexual tension between us exploded that night. After a few shots, she pulled me upstairs to her bedroom.
As soon as the door closed, I pushed her against the wall and kissed her hard. She moaned into my mouth, her small hands grabbing my shirt.
“I’ve wanted you for so long,” she whispered. “I always touch myself thinking about you…”
That was all I needed.
I threw her onto the bed and pulled her skirt up. She wasn’t wearing panties. Her pussy was perfectly shaved, pink and already wet. I dropped down and ate her out like a starving man. Ji-eun moaned loudly, grinding her pussy on my tongue, her thighs shaking around my head.
“Fuck… oppa… your tongue feels so good!”
She came hard in less than two minutes, flooding my mouth.
I stood up, pulled out my thick 8-inch cock, and rubbed it against her tiny slit.
“You sure you want this?” I asked.
“I want you to ruin me,” she begged.
I pushed inside her tight Korean pussy in one slow thrust. She was incredibly tight. Her walls squeezed my cock like a vice as I stretched her open. Ji-eun’s eyes rolled back and she let out a loud, slutty moan.
“Oh my god… you’re so much bigger than my ex…”
I started fucking her harder. The sound of my balls slapping against her ass filled the room. I pulled her top up and sucked on her perky nipples while pounding her deep.
After making her cum twice, I flipped her over into doggy style. I grabbed her slim waist and fucked her like an animal, watching her perfect ass bounce.
“Harder! Fuck your best friend’s sister harder!” she screamed.
I lost control and filled her tight pussy with a massive creampie.
The Sex Party Turns Wild
We went back downstairs. The party had turned into a full-blown sex party. Couples were fucking on the couches, some girls were making out with each other, and the energy was electric.
Ji-eun, still glowing from being fucked, pulled me into the living room. Two of her friends — both hot Korean girls — were already naked and playing with each other.
Ji-eun whispered in my ear, “They want to watch me get fucked again…”
She got on her knees right there in front of everyone and started sucking my cock. Her pretty face looked so innocent even with my thick dick stretching her lips. People started gathering around to watch.
One guy asked if he could join, but Ji-eun shook her head.
“He’s mine tonight,” she said possessively, then deepthroated me again.
I bent her over the couch and fucked her hard in front of everyone. Ji-eun was moaning like a pornstar, not caring who saw. Her pussy was dripping down her thighs as I destroyed it.
“Cum inside me again,” she begged loudly. “Fill your best friend’s sister!”
I pumped another huge load deep into her womb while people cheered.
Later that night, I fucked her two more times — once in the shower and once on her parents’ bed. She let me fuck her tight ass for the first time. She was so tight I could barely last five minutes before filling her ass with cum.
The Morning After
The next morning, Ji-eun cuddled against me, her body covered in hickeys and dried cum.
“This isn’t a one-time thing,” she said, stroking my cock. “I want you to keep fucking me behind Minjun’s back.”
I smiled and pushed her head down.
“Good girl. Now suck your new favorite cock.”
The next morning, I woke up in Ji-eun’s bed with her small, naked body pressed against me. Her smooth porcelain skin was covered in hickeys, and her tight little pussy was still leaking my dried cum from the night before.
Ji-eun stirred and looked up at me with that naughty, innocent smile.
“Oppa… last night was so good,” she whispered, gently stroking my morning wood. “I’ve never been fucked like that before.”
Before I could reply, she slid down and took my thick cock into her warm mouth. She sucked me slowly, her pretty Korean face looking up at me the entire time. I grabbed her long black hair and gently fucked her throat until I filled her mouth with cum.
She swallowed every drop like a good girl.
The Risk Begins
We both knew it was dangerous. Minjun (her brother and my best friend) was supposed to come back home that afternoon.
But Ji-eun didn’t care.
After breakfast, she pulled me into her parents’ bathroom and bent over the sink.
“Quickie before he comes back,” she begged, lifting her skirt.
I didn’t hesitate. I shoved my cock balls-deep into her tight Korean pussy in one thrust. Ji-eun moaned loudly, gripping the counter as I pounded her hard from behind. The mirror showed her perfect reflection — perky tits bouncing, mouth open in pleasure, eyes rolling back.
“Fuck me harder, oppa! I’m your best friend’s little sister… use me!”
I grabbed her slim waist and fucked her like a slut until I pumped another load deep inside her.
We barely finished cleaning up when we heard the front door open.
Minjun was home.
Secret Tension
For the next few days, Ji-eun and I had to act normal around Minjun. But behind his back, it was nonstop filth.
She would text me while sitting right next to him:
Ji-eun: My pussy is still sore from your big cock Ji-eun: Come over tonight. I want you to fuck my ass again.
One evening, Minjun went to the gym. The second his car left the driveway, Ji-eun ran to me wearing nothing but a tiny white thong.
We didn’t even make it to the bedroom.
I fucked her right on the living room couch — the same couch where Minjun and I played video games. I put her in missionary, legs over my shoulders, and destroyed her tight pussy. Every deep thrust made her squeal in Korean mixed with English.
“Too deep! Oppa, you’re hitting my womb!”
I flipped her over and fucked her doggy style while she moaned into a pillow. Then I pressed my cock against her tiny asshole.
“You sure?” I asked.
“Yes… fuck my ass. Make it yours.”
I slowly pushed into her incredibly tight Korean ass. Ji-eun screamed in pleasure and pain as I stretched her. Once I was fully inside, I fucked her ass harder and harder until I exploded, filling her guts with thick cum.
The Second Sex Party
Three days later, Ji-eun told me she was throwing another party.
This time it was smaller — only 12 people — but much wilder. It quickly turned into a full sex party again. Ji-eun was the center of attention.
She wore a tiny black dress with no bra and no panties. Halfway through the night, she got on her knees in the middle of the living room and sucked my cock in front of everyone.
Her friends watched in shock and arousal as this innocent-looking Korean girl deepthroated me like a pornstar.
Then she stood up, bent over the couch, and said loud enough for everyone to hear:
“Come fuck your best friend’s sister again.”
I fucked her raw in front of the whole group. The sound of her wet pussy and loud moans filled the room. One of her Korean friends even came over and sucked on Ji-eun’s nipples while I pounded her.
After I filled her pussy with cum, Ji-eun shocked me.
She looked at the group and said, “Who wants to watch him fuck my ass next?”
Two guys and three girls stayed to watch. I bent Ji-eun over, spread her ass, and fucked her tight hole while everyone watched. She came so hard her legs gave out.
The Close Call
The most dangerous moment came the next day.
Minjun was home, playing games in his room. Ji-eun snuck me into her bedroom while he was just 10 feet away down the hallway.
She rode me reverse cowgirl, biting her lip to stay quiet. Her tight pussy gripped my cock perfectly as she bounced on me. I reached around and rubbed her clit until she started shaking.
Right as she was about to cum, we heard Minjun walking toward her room.
Ji-eun froze on my cock, her pussy pulsing. I quickly put my hand over her mouth as she came hard, her whole body trembling silently.
Minjun knocked on the door.
“Ji-eun? You okay in there?”
She answered in a shaky voice, “Y-yes oppa… I’m fine.”
As soon as he walked away, I flipped her over and fucked her hard until I filled her again.
