Pick the Best Panties
I never imagined a fairly reputable brand lingerie shop would stock stuff like this.
Open Crotch Panty.
T-Panty.
Mesh see-through ones, too.
And even a Beaded Panty.
No, I could understand the others, but beaded panties here? Weren't those only sold at adult shops?
Maybe I was clueless, but they could surprisingly be mainstream...
I couldn't wrap my head around it, but with them displayed so boldly, how could I not buy some?
I picked out several pairs of panties and handed them to Ryu Se-hee.
"Try each one on and show me."
"I wondered why you were suddenly buying me underwear... Ha... So this was your goal all along?"
Ryu Se-hee frowned at the underwear I held out.
"You buy me food and all, so I had my suspicions..."
"Huh?"
"Nothing!"
"Change quickly and show me. I'll wait out front."
"Ugh...! Gimme that!"
Ryu Se-hee snatched the underwear and stormed into the fitting room.
Nothing under her jeans, so changing would be easy, right? Good call telling her to go commando.
I fiddled with my phone while waiting a bit, then her voice came from inside.
"...I'm dressed."
"Ooh~ Wanna show me?"
Swish.
I peeked my face through the curtain without waiting for permission.
The moment I stepped in, there she was—Ryu Se-hee in her underwear.
"Whoa~."
"Ugh..."
Groooan. This was it!
The perverted open crotch panty exposing her pussy wide open.
Her pristine white thighs and the curve of her ass on full display.
Yet she had a proper top on.
This absurd outfit was so damn hot, words failed me.
I wanted to parade her through the mall like this for a pussy-flashing date...!
"No covering with your hands, Teacher. Move 'em. Spread your legs, too."
"...Like this?"
"Lemme snap a pic."
"Wha—!? Hold on...!"
Click! Click!
I snapped photos before she could cover up.
At the camera sound, her hand hesitated midway to her pussy, then dropped back to her thigh.
I took a barrage of shots of Ryu Se-hee obediently showing off her pussy.
"Gorgeous. Could use this as my phone wallpaper."
"You're insane...! What if someone sees...!"
"Psh. Who's gonna see? Oh, try the next pair."
"...So this is why you dragged me out today. You trash."
Ryu Se-hee grumbled as she drew the curtain again.
Rustling sounds from inside, then she was done changing.
"...Okay."
"What's this one?"
"Th... T-Panty."
I couldn't resist T-Panties...!
I immediately stuck my head through the curtain.
Swish.
Ryu Se-hee stood there in the T-Panty, blushing furiously.
"Ooooh...!"
"That good, huh?"
Damn right it was. Fucking good.
"It's a T-Panty, right? Turn around and show me your ass."
"Hah! You sure know what you want."
Ryu Se-hee half-turned.
Her massive flesh jiggled with every move. Wow.
The T-Panty was buried between her ass cheeks—pussy totally hidden!
"...There."
"The T-Panty's swallowed by your asshole. Can't see it well."
"Shut up...!"
"Bend over a bit and spread?"
"Nngh...!"
Ryu Se-hee bent slightly and stuck out her ass.
I could see the crease of her ass crack peeking past the T-Panty.
"Kya...!"
"You're crazy. Really. Even here...!"
"Teacher, even in a T-Panty, your asshole wrinkles are all visible."
"Wha—!?"
Ryu Se-hee frantically covered her ass.
Too late—I'd seen it all. And snapped pics.
Ass wrinkles not even hidden by the T-Panty.
One tug of that string, and her hole was wide open. Total vulnerability. All of it.
"...You saw everything?"
"Yup."
"Eek...!"
Ryu Se-hee's face turned beet red.
"What's wrong? It's not the first time. Your asshole's old news from my place already..."
"Shut your mouth...! Don't... don't say any more...!"
Even as she spoke, her asshole wrinkles twitched.
So sensitive now that just being seen gets her going?
Or maybe... she was remembering last time when I fingered it.
"Wear that to school next week? Oh, with a skirt. Miniskirt."
"Are you nuts...!? How am I supposed to wear this to school! Stairs everywhere...!"
"It's fine. I hear some teachers do PE classes with no panties."
"Who the hell does that...! They'd lose their teaching license!"
Ryu Se-hee scowled hard.
Makes sense—with her teacher pride, no-panty classes were unthinkable.
Wonder what she'd say knowing the no-panty teacher was right next door?
"Anyway, we'll get the T-Panty. Try the next one."
"Wait, you planning to make me try everything here?"
"Yup. How about that see-through one next?"
"Ugh..."
"Don't wanna? Those pics I just took go to the staff group chat..."
"Fine...! I said fine!"
Ryu Se-hee squeezed her eyes shut and grabbed the see-through panties.
Guess I had to remind her of the blackmail now and then.
Swish.
"...Done."
"So pretty, Teacher. See-through—your pussy's crystal clear. This one's my profile pic."
"D-Don't you dare...!"
Swish.
"...At least this one's decent."
"Huh? You into mesh, Teacher?"
"Shut it...! I mean it's the most normal! Who'd like this crap?"
Swish.
"You're insane... Who wears this shit...!?"
"You're wearing it right now. How's it feel? Easy to move in?"
"Don't talk to me...! The beads... Nngh...!"
Ryu Se-hee fidgeted in the Beaded Panty, unable to stand still.
Her thighs clenched, legs trembling.
Even I could tell the stimulation was intense.
If she pulled on jeans like this, the beads would press right in...
Whoever designed it was a genius.
Perfect. Decision made.
"Wear the beaded panty for the rest of our date today."
"Wha—!?"
"Hey."
"Nng...!"
I showed her the latest pics, and her defiant glare softened.
Obedient was so much better.
Man, with her legs spread like that and just the beaded panty on, it almost looked like a high-leg...
And her crotch was getting slick...
The rotor? Or the beads?
Either way.
Just watching her lingerie show was getting too hard to bear.
Her runway had me fully erect already.
Swish.
"Eek...! What...! Why'd you come in!"
"Shh. Don't yell. The staff'll hear."
I lowered my voice, and she glanced around nervously.
Yeah, she wouldn't want the staff seeing her in beaded panties.
"Wh-Why'd you come in? Don't tell me...!"
"C'mon, you know what."
"H-Here...? You serious, Teacher?"
"These spots are hotter for it."
I pressed close, wrapping my arms around her waist.
Just the beaded panty—bare ass cheeks against me.
"Hnn... Ah...!"
"No noise. You know from last time? Quiet."
"I-I know...!"
At my warning, Ryu Se-hee clamped her own mouth shut.
Hmm. Too cramped to lie down.
Standing doggy? We'd done it before—she'd manage.
I rubbed her belly softly and whispered in her ear.
"Stand in front of the mirror."
"...!"
Best part of a fitting room: full-length mirror perfect for watching sex.
"Eek... Ha...!"
Ryu Se-hee braced her hands on the mirror, leg kicked back.
Our eyes met in the reflection—she whipped her head to face the mirror.
Then her own face stared back, so she ducked her head.
So adorably flustered.
I laid my cock on her ass and rubbed gently.
"Mirror doggy, so I'll go slow today."
"Do whatever... Slow or hard...!"
"Want it hard?"
"That's not what I—Nngh, hnn...!"
"Oh. I'll take the rotor out."
Thought about double-stuffing with the rotor, but my cock was too big.
Pound too hard and it might jam against her cervix—hospital trip.
Better pull it.
I crouched, eyeing the ass before me.
"Ugh...!"
Whoa...
Already slutty beaded panty, now layered with her ass—insanely hot!
Beads didn't even cover her pussy fully.
Clit poking out sideways. Labia all visible.
Make her sit on a hard wooden chair at school in this... Fun.
Buy a bunch for Min Yu-ha as a gift, too.
I shoved the beads aside and plunged fingers into her pussy.
"Pulling the rotor. Relax."
"Nng... Hnn!"
Squelch...!
Her insides were scorching hot...
Realized I hadn't fingered her much.
Time to explore.
I thrust fingers deep, groping her walls.
"Nnh...!"
Ryu Se-hee, who'd been holding steady, shuddered violently at one spot.
Squish!
"Nnghaa...!!"
"G-spot, huh."
"Wha's... th—Nngh...!"
She didn't know? She'd need proper sex ed later.
No way she didn't know G-spot.
"It's right here."
Press...!
"Hnnnng...!!"
Her knees buckled and straightened, legs quaking. Super sensitive.
The bead lodged in her asshole nearly vanished as wrinkles spasmed.
"Hah... Haah...! H-Hurry and pull the rotor...!"
"Looking for it. So impatient."
"Faster...! Nngh...! Hah...!"
"That horny for sex? Can't even tell how bad."
"Shut up and fas—Nnghaa!!"
Got it.
The string to the rotor. Yank and out it comes?
I pulled hard.
Squelchhh... Plop...!
"O-Oh...! Nn, nng...! Don't yank there, feels...! Nn!"
"How else to pull? Bear it."
"Eek... N-No... Pulling now... Th-that, hnn...! W-Wai...! A-Ahh!!"
Pop!
Out it came!
Psssh!!
With her juices.
"Ahhhk...!! Ah... Haah...!!"
Pssshhh!!
Face right at her pussy, I took a splash of her fluids.
Mm. Warm.
I didn't dodge—just washed my face with it.
Licked the juices from my lips.
Sweeter and tastier than that coffee earlier.
"Eek... Haa...! Ha...! Haah...!"
"Rotor's out, Teacher. Set it aside. Put it back after."
"Ugh... Hnnng...! A-Again...?"
"You shoved it deep. How far'd you push? Did it yourself, right? Masturbating while inserting...?"
"Sh-Shut up...! It went in on its own...!"
Fine, whatever.
I wiped the juices from my face, slicked my cock with my wet hand.
Stood, pressing my tip to her pussy hole.
"Nnh...!"
"Big breath. Cover your mouth with one hand."
"...Why?"
"So you don't scream."
I took a deep breath, then eased my cock in slow.
Squelchhh...!!
"Guh, nnghh...!!"
"Going slow!"
"J-Just gentle... Nngh...! G-Gen... tle...! Nn! Hah...!"
Squelch...! Plop...! Squish!
Her slick pussy flesh parted as my cock sank in bit by bit.
Rotor-heated, it was insanely hot inside...!
Made sense—teased ambiguously all morning, she must be burning up...!
Squish...! Plop...!
Her pussy sucked greedily at my cock like it was waiting!
"Ah...!"
"Nngh, hnn...! Nn, ngh...!"
Plomp!
I dragged it out slow on purpose.
Ryu Se-hee adapting a bit? Shaking but holding, taking me.
Mirror view, tight space, no noise... Slow sex feeling every wall sounded perfect.
I hugged her waist with both arms.
Squuuish...!
"Nngh...! Nn, haa...! Eek...!"
"Moving slow. Nice and slow."
Squelch! Squish! Plop...!
Gripping her waist, I rocked gently.
Legs tensed, stroking smooth like petting.
Squish...! Plop...! Squelch...!
"Nnghh... Nnng... Hnngh... Nn...! Haah...!"
Ah... Her pussy walls felt so soft...!
Circling hips to caress with my cock.
Squish...! Slrp...! Slorp...!
"Guh, nngh...! Nn, hnn...! Hah...!"
Slow thrusts back and forth, savoring her.
Feels so good I could stay all day. Tightening perfectly at every move... Delicious!
"Nngh...! Teacher...! Nnh...! Nn, haah...!"
Her mirror hand slid lower.
Ah... Wanna cum too...!
"Ma'am?"
Then—a voice outside. Staff.
I froze.
Not us, right?
"Ma'am...? You in there?"
Voice closer. Right at the curtain.
Staff's feet visible under it.
"Ma'am?"
"Ahn...!"
...Calling us for real.
Squuuish...♡
Ryu Se-hee's face paled as her pussy clenched wildly.
