My Sister's Friend is Insanely Good at Sex
“Haa, haa……”
After her first orgasm, Yang Minah spent several minutes catching her breath. I lay beside her the whole time, holding her close and squeezing her breasts.
“Haa, haa… Yuon-ah.”
“Feeling better now?”
“Yeah… haa, I’ve never felt this good before……”
“Think you can keep going?”
“Puhuh, ahaha!”
“…??”
Yang Minah suddenly burst out laughing. I stopped fondling her chest and just stared at her blankly.
What the hell is wrong with this woman?
“Haa, haa… Sorry, it just struck me as funny.”
“What exactly is so funny…?”
“It’s just, that’s the kind of thing I always say to my boyfriend. Hearing it from you felt new and hilarious.”
“Ah.”
“My boyfriend only goes for a second round when he’s in really good condition. Otherwise he just cums twice and that’s it. And even then he finishes way too fast.”
“Is he premature?”
“Not exactly premature, but still way too quick for me.”
“Was I too quick just now too?”
Worried I might have the same problem, I asked. Yang Minah shook her head with a laugh.
“Puhuh, you weren’t that fast. And it was intense enough to make up for it. I actually came a little the moment you put it in.”
As she spoke, she rubbed her own pussy.
“I almost came too.”
“Really? Did noona’s pussy feel that good?”
“…It did.”
I gave her nipple a light pinch while answering. She let out a small “ah” and laughed again.
She really laughs a lot.
“…Yuon, you’re hard again.”
“I’ve been like this since earlier. I almost died waiting.”
“Puhaha, you’re hilarious. You must be popular with girls.”
“Well, I’ve had some popularity, but I never felt much when girls I wasn’t interested in confessed to me. The ones I liked always went for other guys.”
Park Jiyeon had been the first girl I actually connected with… Thinking about it now still felt disappointing.
“Since you’ve gotten over it, why not try asking her out again?”
Yang Minah stroked my cock with her hand, slick with her own foamy juices.
“Nah, how could I do that?”
“Why not?”
“Think about what I’d have to say. ‘I get hard for other girls just fine. Let’s try having sex again. Just give me one more chance.’ Something like that?”
“Ahahaha! Hey, you can’t actually say that! Are you stupid?”
“Then what should I say?”
“Let’s try again! I still like you! Just say something like that. Be a man about it! Right?”
“……I don’t know, thinking about it is annoying.”
I pushed her hand away and got back into position. Flipping Yang Minah over, I grabbed her hips and pulled her toward me. Her small body slid across the bed with a soft rustle.
Her pussy, now wider than before and twitching, was leaking a mix of my cum and her juices.
I rubbed the head against her folds, spreading the mess around, then pushed back inside.
“Hiat…!”
She seemed even more sensitive now. Yang Minah threw her head back, her back arching deeper.
“Huaaa……”
“Feel good?”
“So gooood……”
Smack!
“Ang!”
I gave her big, round ass a slap without thinking. She moaned and wiggled her hips, as if asking for another on the other cheek. So I obliged.
Smack!
“Aaang!”
“Noona’s a pervert too.”
“……‘Too’?”
Shit.
Slip of the tongue.
“Who’s the other pervert?”
“……Me.”
“Puhahaha! Hey, the mood was good and you’re ruining it with jokes!”
I escaped the crisis with quick thinking.
Whew, I let out a mental sigh of relief.
Yang Minah giggled for a while longer before shaking her hips again.
“Fuck me♡”
Smack. I slapped her ass once more, then grabbed her waist. The sharp curve from her plump hips to her narrow waist felt perfect in my hands.
Thrust… thrust… thrust….
“Nngh, hngh, hngh……”
This time I kept the pace slow. Yang Minah didn’t moan as loudly at first.
Every time I pushed deep and pulled out, her juices foamed up around the base of my cock.
“Heuh… heuk… hueut……”
As I gradually picked up speed, her moans grew louder too.
“Ahng, haak… aeueuk……! Haaaeung!”
“Hurk, Yang Minah, does it feel good?”
Thwack… thwack… thwack….
“Good… so gooood… haaak!”
“Did you have sex with your boyfriend today?”
“Hngh… heueuk… heueuk……”
“Answer me.”
Thrust— thrust— thrust—.
“I did… heuk… I did…!”
“How many times?”
“Once…… just once… erk!”
“So you came to me because you weren’t satisfied? Because you wanted my cock inside you?”
“Hngh, heueut…! Aeueuk!”
“No?”
“Yes♡, yes♡! Aaaang! Hiaaang♡♡!”
Squelch, squelch, squelch, squelch, squelch!
“Aaang! Haaak! Hiyaaang! Heueuk♡♡♡!”
‘What the fuck is this?’
I was only moving back and forth, but Yang Minah started rolling her hips and waist, adding her own movement.
The extra stimulation hit hard. In less than five minutes I already felt the urge to cum.
‘Shit, fuck, I’m gonna lose it.’
This was the hip movement of a woman who’d slept with twenty guys.
Yang Minah twisted her waist in circles like she was trying to wring me dry. I couldn’t hold back anymore and came.
Spurt, spurt spurt….
“Hiyaaang… haaeung……”
“Hurk, hurk……”
Even while I was cumming, Yang Minah didn’t stop moving. My oversensitive cock felt like it was melting.
My legs gave out and I collapsed onto her back. I tried to brace myself on the bed, but my arms were useless too.
“Hurk, hurk……”
“Haa… haa… Yuon-ah, how’s noona’s pussy?”
“……Fucking incredible.”
“Uhehet, see? Noona’s the best, right?”
“Yeah…… the best.”
“Noona feels like she could cum again if we keep going. Can you fuck me a little more?”
“……Sure.”
I licked her back to buy time. Every time my tongue swept over the beads of sweat dotting her skin, Yang Minah’s hips twitched.
My cock swelled inside her again. She shook her ass in response.
Squelch, squelch, squelch, squelch—.
“Ah… so gooood…… ahak… ahaeung!”
Thrust, thrust, thrust, thrust!
“Gooood…! Haang! Good, Yuon-ah! Heueuk! Euek!!”
Her moans turned me on even more. It wasn’t just the alcohol or the heat. Even sober, her voice would’ve driven me crazy—the way she screamed without holding back.
On top of that, her short but well-proportioned body from behind. Her large breasts swinging in every direction with each thrust. Her big ass rippling every time my pelvis smacked into it.
Late spring, the weather slowly turning summery and warm. The smell of sweat from walking around in a leather jacket and leather pants.
The scent of cum and pussy juice mixed together, foaming up.
And… the warmth of Yang Minah’s pussy and her godlike hip movements.
I felt my eyes glazing over. My cock felt like it was melting away. So this is heaven.
“Aeuk! …Heueuk♡! Eungat! …Haaak♡!!”
Yang Minah kept lifting her hips. I wrapped my arms around her stomach and breasts, pulling her upright into my lap. Still holding her, I kept thrusting.
Thwack! Thwack! Thwack! Thwack!
“Euek! Euhk! Euhueuk! Eugeuk♡♡♡!”
Reflected in the wall mirror, Yang Minah had her head thrown back, tongue hanging out. Every thrust made spit drip from her mouth along with her moans.
Thwack thwack thwack thwack! Thwack thwack thwack! Thwack—!
I sped up and left my second load inside her. Her breasts squeezed between my fingers, looking ready to burst out.
Yang Minah’s legs wrapped around my hips, as if refusing to let even a single drop escape.

“Haak… haak… haaak… haaak……”
Yang Minah rested her head against my collarbone, breathing hard. Her back arched so much her stomach stayed far from mine.
“Haaak… haaak… Yuon… Yuon-ah……”
“Minah noona… hurk… hurk……”
She tilted her head back to look up at me, then stuck her tongue out toward me like she was reaching out. I met it with my own.
Chup… haak… chureup… chup… haaak…….
One hand rubbed her stomach while the other squeezed her breast. Her smooth, toned belly and her large, soft breasts. Yang Minah stroked my arm, then wrapped her arms around my neck.
“Chup… hueup… chureup… haa, wait… this is hard……”
The position was getting uncomfortable, so I let her down. She flopped onto the bed, panting. Her small, smooth back rose and fell with each breath.
Her pussy was covered in a foamy mix of cum and juices. Her ass crack glistened with wetness.
The hole my cock had just left twitched weakly, pushing out more lewd fluids.
“Haa… haaa… ah… I need to pee……”
“Want me to take you?”
“Haa… yeah… haa… I can’t walk……”
I gave Yang Minah’s cute ass a light slap, then picked her up and carried her to the bathroom. Once I set her down, she tried to sit on the toilet.
“Wait.”
“Haa… huh?”
“I’ll help.”
“…??”
I picked her up again, positioning her over the toilet with her legs spread wide in an M-shape.
“…!! Hey!!”
“Go.”
“Ah, no—!”
“Want help with that too?”
I reached down and rubbed her pussy, circling her clit and urethra. Yang Minah flinched.
“Hueut!”
She held it for a moment, then let out a long, relieving stream.
“Haaaaaa……”
Her body trembled like she was having another orgasm as she leaned back against me.
“Haa… seriously… I feel like I’m turning into a pervert because of you……”
“You already are a pervert.”
“No I’m not.”
“Yes you are.”
“Hey, perverts only see perverts. Pervert eyes.”
“Then noona’s… a pervert pussy?”
“Ahahaha! You’re actually crazy!”
Playing around with Yang Minah like this felt surprisingly natural. Like we’d known each other forever.
Shhhhh—.
I emptied my own bladder too, then washed up with her while we were there.
“Haa…… I used to wish I had a little brother like you.”
“Huh? I was just thinking the same thing. That I wish I had a noona like you.”
“You’ve got Yuyoung though.”
“That’s not a noona. That’s a crazy gorilla.”
“Puhuh, why do you hate Yuyoung so much? She’s such a nice person.”
“Nice? Bullshit.”
Nice? Bullshit.
Ah, my inner thoughts slipped out loud.
How thick is the mask she wears outside if people actually think she’s nice?
“If I’m lying on the sofa watching TV she kicks me and tells me to move because it pisses her off. If I buy snacks she steals more than half. When we get New Year’s money she takes tens of thousands from me. There’s so much.”
“Really? Yuyoung does that?”
“I’m telling you.”
I grabbed Yang Minah’s breasts with both hands. Holding those soft things made me feel a little better.
I finally understood why slime toys had been so popular back then.
Just squeezing her chest however I wanted drained the stress right out of me.
“Ang… it got hard again…♡”
Yang Minah wiggled her ass against my cock, which was now poking her from below.
“Wanna do it here?”
She leaned forward, spreading her pussy with both hands. White liquid mixed with foam trickled out.
I rubbed my tip against her entrance. Yang Minah braced against the wall and shook her hips side to side, urging me to hurry up.
“Hurry♡ Put Yuon’s cock in noona’s pussy♡♡”
Maybe growing up getting hit by Kim Yuyoung had twisted me.
When a girl begs like this, I suddenly don’t want to give it to her right away. I want to tease her a little longer.
So I rubbed my cock up and down her folds without pushing in.
“Ahng… stop teasing meee…!”
“You want it?”
“Yeah…♡ I want it♡!”
“How bad?”
“So fucking… so fucking bad♡!”
I pretended to thrust in, then slid past her pussy instead.
“Hngh…… Hey, are you gonna keep messing around?”
“Noona’s just too cute. Makes me want to tease you.”
“Acting up again?”
“Makes me want to mess with you.”
“Seriously—, should noona just go home??”
“Ah, fine, fine.”
She couldn’t leave yet.
I kept rubbing my shaft against her entrance without entering—then suddenly thrust in hard.
Thrust!
“Huaaaang♡♡♡!”
