Chapter 15: Why the Hell Are We Doing Pussy Sex Practice with the Compensated Dating Class?
Period 5 was pussy sex practice. As the subject most closely tied to the reason Onago High School was founded in the first place, it was treated with the utmost importance among all classes, carrying the highest weight in students' grades.
Students usually practiced various positions with dildos and learned real-world techniques for clenching their pussies, making it one of the most popular subjects. Even kids who slacked off on other studies threw their hearts and souls into this one.
"Everything's fine, but why does it have to be fifth period? We just ate lunch—moving around's gonna be rough."
"Can't be helped. Think of it as training, right? We're onaholes; we can't pick and choose when our pussies get used. If a guy says spread 'em, we spread 'em—no guarantee it's not right after lunch."
Seong-mi soothed Hyeonju's whining as she quickly changed clothes. No uniforms during sex practice. Sure, uniform sex could amp up the excitement in real scenarios, but school classes were just drills. Best to go with the most comfortable outfit possible. (Uniform sex came later in the curriculum, once they'd advanced a bit.)
But going fully naked was too chilly, so most students opted for gym clothes. Not those dowdy, unsexy track suits, though. Tops were skin-tight white gym shirts, bottoms were those blue bloomers that had even gone extinct in Japan. And of course, they punched holes in the nipple and pussy areas to fulfill onahole basics.
Perfect for mobility and intense workouts.
"Ugh... I hate wearing this gym uniform every time."
"Why? It's comfy."
"..................."
Hyeonju silently kneaded her modest tits. With the nipples wide open and the fabric clinging tight, the outfit ruthlessly accentuated a woman's curves. It sure highlighted Hyeonju's not-so-busty figure.
Not ideal for someone whose chest was her complex.
Truth be told, Hyeonju's B-cups weren't behind the Korean average. Wide hips, slim waist—she had plenty of feminine appeal. But this was Onago High School, gathering the nation's—and world's—most promising girls. Of course her body looked lacking here.
"'Cause of your tits? Whatever. Tits aren't everything for an onahole. Your oppas don't seem to mind 'em being small."
"Don't pin 'flat' on me. There's still growth potential."
Just waiting for Mom's massive genes to kick in. Endless possibilities. That's what she believed.
"Or what, transfer to the flat-tit class? You'd be stacked there."
"...No way. I'd die first. Hate that more than anything."
The flat-tit class. A special class for onaholes with notably small chests. They were elite picks with real onahole flavor, but lacking womanly curves made them fair game for teasing. Rumor had it the class existed just for that.
"All 'cause of that jerk... Pisses me off."
"Whoa, why blame your innocent oppa? That's a stretch, even for you."
Seong-mi couldn't hold back. But Hyeonju shook her head stubbornly.
"Nope. 100% his fault. 'Cause when we were kids, he never groped my tits."
"For real?"
Seong-mi blinked in surprise. Hyeonju's oppa struck her as a total tit man—probably obsessed since childhood. Hard to imagine he'd ignore his own sister's rack.
But if true, it kinda explained why Hyeonju hated him so much.
"Dead serious. He only started groping 'em a few months ago. Isn't that hilarious? Shouldn't an oppa regularly massage his little sister's tits to help 'em grow? But he was too lazy for that basic duty. Now he's all grown up, finally acting like an oppa, kneading 'em like crazy—but too late! He wasted my prime growth window with his laziness! Still growing! Still growing!"
She said it twice for emphasis.
Seong-mi doubted massages actually grew tits, but she got Hyeonju's frustration. If she had an oppa slacking on sisterly tit duty, she'd be pissed too.
"Hyeonju, so that's why you're so bratty with him. Makes sense."
"Duh. You think I whine for no reason?"
Honestly, yeah, kinda. But friendship mattered—better keep quiet. Seong-mi offered advice instead.
"Then puff that chest out more. Hunching makes small tits look smaller."
"Don't say small! It's 'cause yours are huge!"
＊
Today's sex practice was a joint class with the compensated dating class. That group handled school-sponsored sugar baby gigs, funneling cash back to the school. Students got early economic experience while still in class, so other classes envied them a bit.
The compensated dating class was full of delinquent types who looked like pros at taking dick. Many had sugared before assignment—perfect fits. But plenty of plain, pure-looking girls too, so criteria weren't absolute. Recommender's discretion, Hyeonju figured.
Gym full of students: cliques chattering, eager ones spreading legs for stretches. Hyeonju followed suit, posing for pussy-spreading stretches.
Then a sleazy voice grated in her ear.
"Huh? Isn't this joint with the regular public-toilet class? What's a flat-tit doing here~?"
"........................"
That drawn-out ending, sarcasm dripping from every word—Hyeonju knew it well. Calming her rising temper, she side-eyed the source: tanned bronze skin first.
Tanned bronze skin. Wavy blonde hair. Model-long limbs, tall stature. Rocket tits packed with femininity, not overwhelming. Heart earrings. Sultry, upturned cat eyes on a knockout face. Obvious cumrag vibes.
Hong Mira. Star onahole in the compensated dating class, eternal rival to Hyeonju since enrollment.
"Oh, whoops. Not a flat-tit—it's you, Hyeonju? Sorry. Your stunted growth fooled me. Forgive me?"
Mira wasn't sorry at all. She shook her torso lightly, tits jiggling for show.
Hyeonju swallowed a torrent of curses.
"Why pick a fight? Fun bothering chill people?"
"Who said fight? I misspoke, apologized. What's with that soy-sauce-cap tolerance? Proportional to your tits?"
Mira casually jabbed at insecurities. For some reason, she always targeted Hyeonju.
Nah, Hyeonju hated her guts too—mutual, obviously.
Hyeonju scanned Mira top to bottom.
"Anyway... where's your gym uniform? Not cold in that getup?"
Mira wore no gym clothes: just black fishnets, garter belt, lingerie corset. No panties, no bloomers.
"Nah? Gym clothes aren't mandatory—just comfy stuff. This works. I'm hot-blooded... and why hide a killer body?"
Mira shimmied her tits and ass. The lewd jiggle drew Hyeonju's eyes—infuriating. Even she couldn't resist those hypnotic fruits; guys would drop dead.
But admitting it? Never. Hyeonju turned away casually, smirking slyly, muttering just loud enough.
"Ew, tacky. No wonder he skipped making you his dedicated toilet and dumped you in compensated dating."
"...What'd you say, bitch?"
Mira's face hardened. Hyeonju savored the win, puffing her nonexistent chest to meet Mira's height.
"Huh? Did I lie? You wanted to be my oppas's dedicated toilet, right? Tough luck—he doesn't like cumrags like you. Probably just toyed with your pussy for three days straight, then tossed you back. Bet he doesn't even remember your name. Duh—with how many onaholes he uses daily? Should've trained your pussy better. Might've gotten more attention."
"You done talking shit?!"
Mira grabbed Hyeonju's collar in rage. Hyeonju glared back, unyielding.
School rules banned onahole-on-onahole violence—what could this bitch do? They locked eyes, gripped and glaring, standoff lasting moments... until Mira let go first. Tension eased.
"...We'll settle this later. You ain't getting away."
"Hmph! I get my pussy pounded by him daily~ Nyah nyah~"
Hyeonju stuck her tongue out behind Mira—high-school childishness at its worst, but who cared? Petty wins felt best sometimes.
Then the gym doors opened. In crawled the sex practice teacher—on all fours. A man strolled in, hips glued to her raised ass.
He spotted Hyeonju, waved cheerfully.
"Yo. There's my Hyeonju."
Oppa.
