It's Not Like a Date or Anything!
"You've all worked hard today. Now that classes are over, those with club activities should stay, and everyone else is free to go. I assume you already know this without me saying it, but even outside school, as students of Onago High School, don't forget your duty as onaholes and practice it diligently. Dismissed!"
Teacher Jeong Hana's closing announcement was clear and concise. Sending students home quickly without making them wait unnecessarily was part of a teacher's responsibility—at least, that's how it seemed to those who thought that way. It was perfect for them.
The current time was 3:30 p.m. Unlike typical Korean high schools, Onago High's schedule was almost as short as middle school's. This was due to the principal's philosophy and the recommender's policies: dragging out classes didn't cultivate better onahole qualities. It made more sense for social experience to let them do club activities on their own or head out to serve men's cocks directly, rather than being cooped up in school.
Whatever the reasoning, for the students, an early end to school was always a win. Sure, classes here were way more fun than at other schools, but nothing beat pure freedom. They weren't going to college anyway after enrolling at Onago—wasting their youth locked in school would be a shame.
"Hyeonju, wanna hit karaoke today? We're rounding up the crew, but we're one short."
"Nah, sorry. I'd love to, but I've got somewhere to be. Next time, yeah?"
"Again? You've been ditching us lately. Kinda bummed out here..."
"Ahahaha..."
Hyeonju brushed it off with an awkward laugh. She had no choice—unlike her, all her friends were full-on onaholes. Even a casual hangout could turn into an orgy the second some guys showed up, leaving her no room to join in. If she were an onahole like them, maybe, but as Oppa's dedicated toilet, she couldn't butt in. So she ended up avoiding them.
Besides, she really did have plans today.
"Sorry for real. Next time, promise! Gotta go!"
Hyeonju grabbed her bag and bolted out of the classroom. Instead of heading to the school gate, she made a beeline for the staff room. She flung the door open without a second thought, and a thick wave of semen stench hit her like a punch to the nose.
The staff room was a place students generally avoided, but Hyeonju's eyes sparkled as she stepped right in. A quick scan, and there was her target: Oppa, casually lounging in Teacher Seo Min-jeong's chair, with the original owner perched on his lap, her pussy getting railed.
"Oh, Hyeonju? Classes all done?"
"Yeah."
Short reply, and she just stood there waiting. Interrupting while he was using his cum dump would've been bad manners. Unlike Oppa, Hyeonju actually followed etiquette.
Min-jeong, impaled on Oppa's lap and getting her pussy pounded, let out a dumb "Ooh♥" every time his groin slapped her ass. Her mouth hung open in a brainless ahegao, pure idiot bliss. A far cry from her usual quiet, expressionless face—this was peak braindead bitch mode.
Her language skills seemed cock-melted too; nothing but cat-in-heat moans escaped her lips. During pussy sex practice, she'd managed to explain the lesson to students even mid-thrust, so this was just pathetic by comparison.
Well, getting turned into that by his dick is par for the course. Those other teachers holding it together are the impressive ones—Min-jeong's not that hopeless.
Hyeonju decided to cut her some slack. Min-jeong was generally a bit dimmer than the other teachers, so the bar was lower. Strict standards for the skilled, lenient for the strugglers. A little unfair, but that's human nature.
Oppa hummed along happily as he fucked Min-jeong's pussy, then hilted deep inside and unleashed a massive load. Semen erupted like lava, flooding her womb and overflowing to splatter on the floor under gravity's pull.
Hyeonju almost instinctively licked up the wasted cum on the floor but caught herself. No way, that's too slutty.
"Phew, feels great~ Min-jeong's pussy is getting tighter every day. This time she didn't cum her brains out on every single thrust. You've been putting in the work, huh?"
"Y-yes... Th-thank you so much for fucking my worthless pussy... L-lately... I've been reading erotic novels every day and fapping to train it... If the training's paying off... I'm relieved..."
"Mm! It's paying off big time. Glad I spotted that rough gem in the library and brought her to Onago. She's got room to grow, but this progress means a bright future ahead. You did great. Worth popping your virgin pussy for."
"Haaah... Th-thank you..."
Oppa patted Min-jeong's head—clearly older than him—like a proud owner, doling out praise. She blushed and shyly murmured her thanks. As his dedicated toilet among the teachers, she got these intimate moments. Dedicated toilets occupied a different lane from regular onaholes.
Hyeonju watched, a strange wave rippling in her chest, but she couldn't voice it. This wasn't the same as some random onahole like Mira.
"...My pussy got your cock all dirty... I'll clean it properly..."
"Yeah, thanks."
Min-jeong kissed Oppa's still rock-hard cock post-creampie, then stretched her small lips wide to stuff it into her mouth. Cleaning the dick dirtied by her own pussy with her mouth-pussy was standard etiquette for all onaholes and toilets.
She slurped noisily, licking him clean while fingering her own pussy. Linking cocksucking with pussy orgasms—conditioning her body for climax reflex. Even if she seemed unreliable, a teacher's thoroughness shone in these details.
With Min-jeong cleaning him, Oppa had time to chat. "So, what's up? School's out—shouldn't you be heading home? Or... did you miss your oppa and come for a walk home together? That'd be adorable."
He grinned sleazily, spouting nonsense. Hyeonju snorted in disdain.
"Pfft, as if. Don't flatter yourself—why would I wanna walk home with a loser like you? Ego much? ...Well, not totally wrong, but... You know we've got somewhere to go today."
"Hm?"
Oppa blinked, puzzled, arms crossed and chin stroked in thought. Nothing clicked. Had he set something like that? Too lazy to dig deeper, he asked straight up.
"Seriously, drawing a blank here. Did we have plans or something? I don't forget stuff like this usually."
Hands on hips, Hyeonju snapped.
"Dog collar! You promised to buy me a new one as thanks for cleaning up your onahole yesterday! Ring any bells? We're going shopping together!"
"Oh? That? Right."
He nodded like it just hit him.
"Can't you just order online? Why bother going in person?"
"Online pics don't match the real thing sometimes. I wanna see and pick it myself. So come on."
"Hmph." Oppa grumbled but nodded—then flashed a creepy smirk. "In that case, you could just take my wallet. Looks like you wanna date this oppa, huh? Cute little thing."
"Wh-what?! Gross! Total delusion! Why would I date a creep like you...!"
Her words spat venom, but her voice trembled, cheeks flaming red—just a bitch in heat.
Adorable slut.
"Whatever, I'll tag along. Been ages since a brother-sister date. Sounds fun to me."
"I-it's not a date...!"
Ignoring her fading protests, Oppa pulled out of Min-jeong's mouth-pussy. He admired the glossy-clean cock with a satisfied smile, then as thanks, ground his balls into her face. She sniffed greedily, not missing a whiff, and squirted pussy juice in response.
"Did I tell you to keep a training journal, Min-jeong? Doing good?"
"Y-yes... Ever since you first fucked my pussy... Not a single day missed... Logging fap sessions and every AV I used as reference... All recorded properly..."
"Good girl. Gonna publish it later, so keep it detailed. Lemme see... Take off your top."
Min-jeong stripped her upper clothes without hesitation and handed them over. Oppa jerked off quick and splattered cum all over them.
"Use this as fap fuel today. Reward for your pussy's growth—good job."
"Ah... Th-thank you so much..."
Min-jeong hugged the cum-soaked top like treasure, genuinely touched. Looked like she had at least a week's worth now.
Hyeonju felt a twinge of envy but scoffed too. Hmph, just cum-stained clothes? I fap to his used panties daily.
Oppa patted Hyeonju's shoulder after rewarding Min-jeong properly.
"Alright, let's go? Kinda excited for this sister date after so long."
"No, it's not a date!"
