My Sister's Friend Ripens So Perfectly
The wet sounds of kissing filled the room—chuup, chuurup, chuuruup—.
We devoured each other's lips like we were starving.
My taste lingered on Yoon Seona's lips, and hers on mine.
“Chuup… haa… chuup, chuup… chuurup….”
As if everything we'd done back in my room and at the bar earlier hadn't counted as real kisses, Yoon Seona attacked my mouth with fierce hunger.
How the hell had she held back for so long?
“Chuuruup, hurrup— chulup— hurruruup—!”
She sucked every drop of saliva from my mouth. I returned the favor just as greedily, drinking down all of hers.
Gulp….
I finally started moving my hips.
I couldn't hold back anymore.
Just rubbing my cock inside her hot, tight pussy felt like it might make me cum on its own.
If I hadn't been drunk earlier, that single thrust probably would've finished me.
“Hut…!”
I pulled back slightly, then drove in deep. A hot puff of breath burst from Yoon Seona's nose.
Gulp… gulp…♡
Every time my rock-hard cock plunged into her soft folds and pulled back out, a lewd, wet sound echoed between us.
I flexed inside her, scraping against her upper wall—
“Hiyaang—♡!!”
A loud moan tore from Yoon Seona's throat.
Whoa, that startled me.
That one was almost on Yang Minah's level.
“N-Noona, keep it down a little.”
“I can't help it… haa… it's too hard to hold back…♡”
“Still, try to stay quiet. I'll kiss you the whole time.”
“Haaang… okayyy…♡ haaang♡ chuup—♡”
Chulup, chup, chuuruup——.
Gulp— gulp— gulp— gulp—.
Every thrust made her shoulders shake. Even though I kept her luscious lips sealed with my own, she couldn't stop the moans from leaking out.
“Haut… chup… haeung… chuup… hiyaang!”
“Chup… chup, chuup….”
“Yuon… Yuon-ah…♡ haaak!”
Thrust, thrust, thrust, thrust!
The urge to cum was rising fast. I picked up the pace.
Yoon Seona's arms tightened around my neck.
Thwack—!
“Hauuuuuuuuup——♡♡♡!!”
Spurt— spururt—.
While I pumped my load into the condom, her inner walls squeezed and milked my cock like she was desperate for every drop. She massaged me as if begging for my cum.
Squeeze, squeeze, squeeze….
Squirt, squelch….

“Hiyaang… hiyaang… haeung…♡.”
“Huk… Yoon Seona… Yoon Seona….”
“Haak… mmm… Yuon… Yuon-ah…♡.”
We stroked each other's cheeks, and the gaze we shared held something far deeper than simple lust.
When I didn't look away and kept staring into her eyes, she met my gaze with equal intensity.
Our breathing fell into perfect sync. Our heartbeats matched. Time stretched out endlessly.
“Haa… haa….”
“Whew. Noona, you came so much again.”
When I pulled out, a small lake had formed beneath her. You could probably dig a well there.
“Haeu… why are you saying such embarrassing things….”
The Tomato—her face dyed bright red—covered it with her slender hands.
“Our tomato's perfectly ripe now. Time for harvest~.”
“Hey, come on…!”
She lightly punched my chest with a weak fist. It felt like getting hit by a cotton ball.
“Heh heh heh. But Noona, your way of talking is so proper. You don't even swear.”
“Well… I don't like swearing….”
“Huh. I've been swearing a lot around you, haven't I….”
“……It's okay when you do it.”
“Really?”
“When you swear… it sounds good.”
Yoon Seona blinked up at me with wide, innocent eyes. She looked exactly like the heroine of a romance manhwa.
Wow.
She was making me hard all over again.
“I like hearing you talk too, Noona.”
“…Really?”
“Yeah. It's insanely hot.”
“Pfft, what kind of line is that?”
“I'm serious. Look.”
I pressed my newly hardened cock against her stomach. The slick, obscene juices coating it dripped onto her skin.
A tiny puddle formed around her navel.
“…….”
Without a word, Yoon Seona reached out and began stroking me.
“It's really… so big….”
Stroke, stroke, squeeze, fondle… stroke, stroke….
She played with it like it was the most fascinating thing in the world.
She'd been like this at the bar too. She seemed far more interested in lewd things than her shy appearance suggested.
How had someone who loved this so much stayed a virgin until recently?
Well, it was great for me.
“You like it that much?”
“……Ah!”
She yanked her hand back in surprise.
Why get embarrassed now?
“Heh heh, you can keep touching.”
“……I'm good.”
“Please touch it more, Tomato Noona.”
“Hey, stop calling me that old nickname~.”
“I should change your contact name to Tomato too.”
“Are you seriously going to keep teasing me?”
“It makes me want to tease you even more.”
Chu.
Her reaction was so adorable that I gave her a quick kiss. The corners of her mouth curled up slightly.
Her fake pout had been exposed immediately.
“Ugh, seriously. Yoon Seona, what am I supposed to do when you're this cute? Chuup—.”
“Chuup—. I'm not cute… chup, chuup….”
We started kissing again, but when she tried to touch my face with the hand that had been stroking my cock, I quickly grabbed her wrist.
That hand was still sticky with my cum.
No matter how beautiful and lovable she was, that was a bit much.
She looked just as startled as I felt, eyes wide as she stared at me.
“W-Why…?”
“Ah, no… I just wanted to try something.”
I made up an excuse and lifted both her arms above her head.
Her pale armpits were completely exposed.
I buried my face there—not to sniff, but to slowly drag my tongue across the skin.
“Hiyaak—?!”
Yoon Seona flinched violently and started squirming.
“W-What are you doing?!”
“I don't know, it just looked really lickable.”
“D-Don't! It gives me goosebumps!”
“Goosebumps…?”
She glared at me with a genuinely angry expression.
…Yang Minah had loved it though.
Guess it wasn't for Yoon Seona.
When I pulled away with a disappointed look, she licked her lips and spoke softly.
“Don't lick there… there are other places…”
“Other places? Where?”
“Right next to it… there's a much better spot…”
“Hmm, the other armpit?”
“Yah~ Stop joking around~.”
“Okay, okay.”
Chuckling, I moved my mouth to where she wanted.
I licked a long, broad stroke from her armpit down along the curve toward her breast, then continued lower.
“Haeuu….”
I made a big half-circle downward before latching onto her breast like I was taking a huge bite out of a steamed bun.
“Haeut!”
“Chuuap… chuuap….”
“Hut! Haak, haeung!”
I used only my lips at first, then took another big mouthful and gently nibbled her nipple with my teeth.
“Hiyaang♡!!”
I lightly bit down on her fully erect nipple and rolled it with my tongue. Yoon Seona twisted and writhed beneath me, hips squirming, legs kicking out and pulling back as she lost control.
Chulup— chuuap— chuurulup, chulup—.
“Haeuuung! Haeuuung!”
I switched sides, using my fingers on one while my mouth worked the other.
“Haup— chuuap—.”
“Hiyaang—!”
One nipple rolled under my tongue, the other between my fingers.
Soon, a fountain of pleasure erupted from between her legs.
“Hyaaaang—♡!”
Squiiish— squiiish— squiiish—….
Before her trembling fully subsided, I quickly rolled on a fresh condom and positioned myself between her thighs. The moment I pressed my cock against her entrance, Yoon Seona frantically tried to cover herself.
“Haang… not yet, haat… not yeeet… I'm too sensitive…”
I gently took her hands in mine. She immediately laced our fingers together.
With our hands joined, I pushed my cock deep inside her.
“Hiyaaaaang—♡♡♡!!”
We spent the entire night biting, sucking, thrusting, and getting fucked until we were both completely satisfied.
When we finally lay side by side, I offered Yoon Seona my arm as a pillow. She rested her head on it. The faint, clean scent of shampoo drifted up from her crown.
“Haeu, I think I'm going to be swollen down there tomorrow…”
She muttered while rubbing her inner thighs.
“Then I'll put some medicine on it. Should I use my hands, or my mouth?”
“Uhu hu, you're so silly.”
“Want to shower together?”
“N-No thanks.”
“Why not?”
“It's embarrassing…”
The way she twisted her body while saying that was adorable.
“Haha, wait—after all the crazy sex we just had, you're embarrassed about showering?”
“Sex is sex… showering is different…”
Wasn't sex the more intense one…?
Women's logic was honestly hard to understand.
Yoon Seona went to shower first while I lay in bed resting.
But the sound of her washing, the splash of water… it kept making my cock twitch and harden again.
The truth was, I was still burning with desire and wanted to go another round, but she'd looked so exhausted that I'd stopped.
‘Hmm… maybe I'll just jerk off.’
Feeling a little regretful, I grabbed my phone. I put in my wireless earbuds and played the video Seo Hyeonji had sent me.
Jerking off to Seo Hyeonji's slave declaration video right after fucking Yoon Seona felt insanely good.
I kept the condom on and replayed the video over and over while stroking myself. By the fifth time, I came. My semen trickled weakly into the condom, just like Yang Minah's juices.
“Whew…”
I'd just finished cleaning up when Yoon Seona came out, drying her hair.
“Haa, that feels so refreshing.”
“Aw man. I should've harvested you when you were fully ripe earlier.”
“What are you even saying~.”
I took my own shower, then pulled her into my arms on the freshly laid sheets.
Her hair smelled like the same shampoo I used. Her skin carried the same body wash scent.
“Sniiff— haa—.”
“…Why are you smelling me?”
“Because I like it.”
“…That's embarrassing.”
I gently kneaded her breast. Since she wasn't wearing a bra under the t-shirt I'd lent her, I could feel her bare skin immediately.
No bra? Wait, then down below….
I slipped my other hand into the shorts I'd lent her and felt smooth, bare skin. No panties either.
“You're not wearing underwear?”
“……Haeu.”
Yoon Seona gave a tiny nod. Her ears were already turning red.
“Next time, bring lots of underwear.”
“…….”
Another tiny nod. The tomato was ripening again.
“Or just leave some here.”
“…….”
She buried her face in my chest and gave yet another tiny nod.
She was so cute I thought I might die.
I saw Yoon Seona off early in the morning, came back, and lay down again—only for the doorbell to ring.
Ding-dong—.
“…Who could that be?”
I wasn't expecting anyone.
Maybe they pressed the wrong button. I stayed still.
Ding-dong— Ding-dong—.
It rang again.
Did Yoon Seona forget something? No, she'd taken everything with her.
Then… was it Seo Hyeonji?
I threw on some clothes and opened the door, but the person standing there was neither Yoon Seona nor Seo Hyeonji.
“…Who are you?”
A woman I'd never seen before, with hair rollers in her bangs. She was a bit taller than Yang Minah and had a very fierce expression.
“I'm your next-door neighbor.”
“Ah, yes.”
“Excuse me, but you're way too loud.”
“…Pardon?”
When I stupidly asked her to repeat herself, she let out a huge sigh and looked up at me.
Then she scrunched up her face and shouted.
“Seriously, fuck! I tried so hard to hold it in and not say anything, but you're too fucking loud!! You horny fucking bastard—!!!”
Her voice echoed loudly down the hallway. I flinched in shock.
I quickly bowed my head.
“S-Sorry!”
“It's not just one or two days… and it's not just one girl… how many girls are you fucking?! You animal bastard, fuck!”
“…….”
Okay, that was a bit harsh… No, never mind.
Since it was my fault, I stayed quiet and kept my head down. Thankfully, my polite attitude seemed to calm her a little. She glared at me with a slightly softer expression.
“If you make noise like that one more night, I'll get all the neighbors in the building together, break your door down, and throw you out.”
“……Yes ma'am. I'm sorry.”
Tap tap, beep beep, beep beep beep— click— SLAM!!
She slammed her own door shut violently.
‘Fuck….’
I was screwed. Sex at my studio apartment was officially over.
I'd started living alone so I could fuck my girlfriend freely without worrying about anyone once I got one in college.
Finally, my happy sex life with Yoon Seona, Seo Hyeonji, and Yang Minah was about to begin.
Now I'd have to pay rent here and motel fees on top of that.
Fuck!!
