'Volunteer Service' in the Staff Bathroom
"O-okay, then."
Ryu Se-hee approached me cautiously.
"I'll give you my full devotion... nipple-licking handjob service..."
She gently grasped the shaft of my cock with her hand. She hesitated for a moment.
Then she steadied herself and wrapped her fingers around it.
With her other hand, she slowly trailed down my chest.
She tugged my shirt halfway off and brought her lips to my nipple.
"...I humbly offer."
Ryu Se-hee's soft lips touched me.
Kuht...! So soft... feels amazing!
This is way better than I imagined.
I get it now—why guys make women suck their nipples.
"Whew... You're good at this, huh? That line you just said. It got me hard."
"Shut your mouth...! Kuht...! You told me to say it, Tae-oh Teacher!"
Ryu Se-hee yelled, clearly embarrassed.
Yeah, that was something she'd never say on her own. I had to threaten her over and over just to get it out, but... worth it.
"Wanna try it again? I wanna hear it one more time. 'Devoted nipple-licking handjob...'"
"Not a chance—never again!"
Ryu Se-hee glared at me like she wanted to kill me. Her lips, still clamped on my nipple, parted to bare her teeth like she was about to bite.
Hmm... Looks like her heartfelt service spirit hasn't bloomed yet. What a shame.
Taming her is tricky. She's no ordinary feisty cat.
But that's what makes her delicious.
She curses with her words, but her mouth keeps going.
"Slurp... lick... sluuuurp...!Chup...!"
She's licking my nipple, making me feel so good, right?
Her hand on my cock starts moving slowly too.
Stroke... shh... stroke... shh...!
"Ngh... It's so heavy..."
"Gotta be big, right? Can't even wrap one hand around it."
"...How big is it?"
"Measured it last time—24cm, I think."
"T-twenty-four...!?"
Ryu Se-hee flinched in shock.
Yeah, even I think 24cm is a monster. Especially for a virgin.
The only bigger ones she's probably seen are in Western porn.
Her hand wasn't really gripping it—just resting on the shaft, stroking lightly.
Stroke... shhh... stroke...
"I-is this right?"
"Yeah. Kuht... Feels good. Keep stroking like that while you lick my nipple."
"You're insane... Kuh. Is this what you call service? You like this shit...!?"
"Of course. There's even a pro term for it. What was it... chikubi nametekoki?"
"What the hell is that...! Don't spout weird crap!"
"Hey, don't stop—keep licking."
"I know what I'm doing...! Grh...Slurp. Chup, sluuuurp...!Slurrrp..."
Ryu Se-hee shyly stuck out her tongue and lapped at my nipple.
Has she even kissed before? Her tongue work suggests not.
If so, she's doing cock-sucking and nipple-licking before her first kiss.
"Sluuuurp... How did I end up doing this...!"
Ryu Se-hee grumbled while diligently licking my nipple.
While handjobbing and nipple-licking, she glanced at me, then suddenly bit down hard.
"Ow... fuck!"
"Hmph... hurts?"
"A little."
"You ignored me when I said it hurt yesterday... Kuht... This is all you can take?"
Crunch. Clamp...!
Ngh...! She's gonna keep biting?
But... this feels kinda good?
"It hurts, but it feels good too. Like this?"
"What...!?"
"Do the other one."
"Y-you're... crazy!? For real! Tae-oh Teacher, you're a total perv!?"
Ryu Se-hee looked at me with genuine contempt.
No, no—that makes me sound like a masochist.
I don't have those tastes.
What satisfies me is that the mouth that spat curses at me just days ago is now devotedly licking my nipple.
It's an overwhelming sense of domination words can't capture.
"Slurp... chup, sluuuurp... slurrrp..."
"Ah~ You're doing great."
"Quiet. ...Slurp."
Look at her. Licking so earnestly.
She could bite hard if she wanted, but she chews just right—perfect pressure that feels amazing.
Great school service. Service points: 1.
Time for a reward.
Sloooowly...
"Hn...!?"
I reached for Ryu Se-hee's ass.
Grabbed a handful of that plump flesh. Soft and yielding.
She jolted.
"Ugh...! Do you have to touch there?"
"Feels good, doesn't it, Teacher?"
"Not even a little...! It's gross."
"Didn't seem that way yesterday. When I smacked it here."
Smack!
"Ngh...! Grhng!"
"See?"
"Th-that was just because it hurt! Don't get weird ideas!"
Ryu Se-hee yelled indignantly.
If it was just pain, why did her ass clench so tight?
She was extra sensitive there when I fucked her yesterday too...
Is this her erogenous zone for real?
Easy to test.
Shove...
"Nngh!!"
I slid my finger between her ass cheeks, and her moan echoed loud.
Her ass flesh wrapped around my finger. So warm...
"Teacher, even if no one's around, you can't moan that loud."
"I-I know...! I know...! Kuht...! Wh-why shove your finger there!?"
"You seem to like it. Like this..."
"Ah, hnnngh!!"
"Told you."
"Kuht...!"
"Your hand stopped. This is service time."
"O-okay, kuht...! Okay, so stop touching... stop...! There, ...hnnngh!!?"
Squelch...!!
Oh.
I'd fingered it yesterday too. Her asshole.
She was super sensitive around there.
She'll deny it, but this is definitely her weak spot.
"St-stop... not there... hnng! D-don't...!"
"Your weak point?"
"N-no...! It's just, ungh...! Don't! It's dirty...! That's why!"
Dirty? Nothing dirty on Ryu Se-hee's body.
Pretty girls don't have that.
I dug my finger deeper, rapidly stroking the wrinkles of her asshole.
Scritch-scratch...
"Nnnghiii...!! Ngh, nng...! Ahak...! D-don't...! For real, Teacher...!"
"Your hand keeps stopping, Teacher."
"I-I'm doing it. My hand's moving, so please. Stop... grhng!!"
Stroke-stroke-stroke-stroke-stroke...
Ryu Se-hee gripped my cock shaft and stroked up and down.
Mmm. Clumsy movements. First time handjobbing, after all.
But the teacher who tormented me daily is now earnestly jerking me off, however awkwardly.
That fact alone could make me cum a few times.
Stroke-stroke-stroke-stroke...
Squelch... squish... tschk...!
"Ngh, hn... ha...! Ungh...Hn...!"
She stifled her moans as her hand worked busily.
Can't just sit idle.
I circled my finger gently, teasing her asshole over and over.
She twitched and clenched each time—adorable.
Someday, I wanna shove it in here too.
Dying to see her face when I finger-fuck her shithole...
"Pl-please, grhng...! Teacher, up to here... stop... kuht... hng... stooop...!"
I shook my finger between her plump cheeks a few more times.
Kept rubbing her weak spot...!
Squeeze...!
Ngh!
Sudden tension in her ass.
It clamped my hand so tight it hurt!
"Ngh, hnnngh...! No... don't...! Hnnnngh!!"
Shudder-shudder...
Ryu Se-hee writhed.
Did she just cum from asshole teasing?
"Kuht...!"
Panting, she gripped my cock hard.
Kuht... Feels good...
"Can't hold it, Teacher. I'm gonna cum too!"
"Hn... nng?"
"Ah... cumming!"
Spurt-spurt-spuuurt!Spluuuurt!Spuuurt...!
Blissful ejaculation...
Semen gushed from my tightly gripped cock, splattering the bathroom wall and floor.
Worlds apart from jerking solo.
The clumsy strokes. Uncontrolled grip. Nails grazing lightly.
Didn't know a handjob from a female teacher felt this good.
Easy to do secretly at school too. Gotta make this regular.
"Kuht... All done?"
"Ah~ Yeah, Teacher. You jerked me off so well."
"Shut up...! Flattery gets you nowhere. Ha..."
Suddenly, Ryu Se-hee bent at the waist.
Brought her face close to my cock and licked it clean.
"Mmm... hoo...!"
"Ooh...!"
"Slurp... suuuurp...!"
Ryu Se-hee gave me a thorough cleanup blowjob.
Oh yeah—I told her she has to clean my cock after I cum.
She remembered. Good student. Teacher's pride.
Well done.
Pet her head as a reward.
"Kuht...! Don't!"
"It's praise. Praise."
"You think I want your praise? Mmph... hoo...! Ngh. I have no choice—it's an order...!"
Fair enough.
Though for "no choice," she's using her tongue pretty devotedly.
After rolling it around thoroughly to clean every drop of cum, she finally stood up.
"Hoo... slurp...!Kuht... Good now? That's enough."
"Spotless, Teacher. You could switch careers to cock-cleaner."
"What cleaner...! Ngh! Quit the nonsense! C-can I go now?"
"Ah~ Hold on, Teacher."
"What!"
"Gotta clean this too. The wall and floor."
I pointed to the semen splattered on the bathroom wall and floor.
Ryu Se-hee trembled, then whipped her head away.
"Y-you want me to lick that up...?"
"Who said lick? Use toilet paper."
"You can do that yourself, Tae-oh Teacher!"
"Better together. ...But were you thinking of licking it?"
"Shut up!"
Riiip, rip, rip...!
Ryu Se-hee spun and tore off a ton of toilet paper.
"Clean it thoroughly. Can't leave traces."
"I know...!"
Ryu Se-hee scrubbed the semen off the wall like erasing graffiti.
Brows furrowed in anger, but meticulously wiping every spot—teacherly, I guess?
Can't just watch—
Clunk!
"Ugh. Gotta shit."
A voice from outside the stall.
That voice...
Thud!Clank. Clank.
Someone entered the opposite stall and locked the door.
That voice... Park Sung-hoon?
Fuck. That bastard again today. Unlucky day.
We finished up, so we should leave... but now?
Leave now, or wait him out?
As I pondered, Ryu Se-hee looked at me anxiously.
Unusually scared expression. Face flushed from her recent orgasm.
Sweat beading on her forehead, stray hairs on her cheeks. Semen at her lips...
"Teacher."
"...What?"
I patted her shoulder.
Whispered tiny, pointed at the toilet.
"Hands on the seat, ass out."
...
No holding back.
She's too fuckable to just let this slide.
