Cowgirl Practice Starts with Observation First
"Haa... haaah, ahh... ♥ Oh, kept you waiting, huh? Ungh♥ Oh, our recommender's joining today's class. While class is in session, I'll be playing the role of his onahole first, so bear with me. Nngh♥ Haaahhh, my womb feels so gooood..."
"Yeah, so let's get along. You've all seen audits like this before, right?"
Oppa said this from behind the teacher, arms wrapped around her onahole belly. Her jiggling breasts drew the eye with every thrust of his hips. A guy barging into the school and fucking a teacher outright—but no one batted an eye. Like Oppa said, this wasn't their first rodeo.
As the teacher had mentioned, he was the one and only man with free access to the school—Hyeonju's Oppa. Even at an Onago High School specializing in onaholes, men needed the principal's approval to enter campus. Oppa was the exception, thanks to his huge role in founding the place.
Without his help—the only guy in the country with unrestricted rights to turn women into onaholes—this school never would've existed. In gratitude, they'd granted him special privileges to come and go as he pleased.
Sure, students at an all-girls sanctuary might resent a man wandering in freely. But not here—not these students, anyway. If anything...
"Haa... Teacher's so lucky. Getting to be that magnificent cock's onahole? The best, right? Being a real teacher is like holding office."
"You never forget that dick once you see it. Ah, dangerous... my clit's already throbbing."
...they rubbed their thighs together, envious of the teacher impaled on Oppa's cock. These girls were elite onaholes already, most having been used by Oppa at least once. So it was only natural for their pussies to heat up at the sight of a dick that could subdue any female instinct just by existing.
The only one pissed at Oppa's arrival? Hyeonju.
That jerk... If he was coming, shouldn't he have texted? No, more importantly, shouldn't he use his little sister's pussy first and foremost...?
Of course, that didn't mean Hyeonju wanted Oppa's cock. Absolutely not. This was just general principle. Any brother naturally prioritizes his sister-onahole over others. Her pussy wasn't feeling neglected or anything. No way.
"He's too cool. The absolute best. I've seen tons of cocks, but that one's number one. If I could serve just that one from now on, I'd never need another..."
It was Mira's voice. Hyeonju barely stifled a snort. What bullshit from the original class slut?
Oppa wouldn't give a shit about a girl like her anyway. Glancing sideways, Hyeonju saw Mira blushing like some lovestruck maiden, fidgeting her fingers in a way that didn't suit her at all. The sight nearly turned Hyeonju's stomach.
Filthy cumrag acting all pure and innocent.
"E-even with our recommender here... haat♡ We'll proceed with class as normal. Everyone, grab the dildos from that corner over there."
Seung-a managed to keep things going despite Oppa relentlessly pounding her pussy—teacher experience paying off. Novices sometimes just moaned through the whole period without advancing the lesson at all.
As instructed, they fetched dildos from the gym corner—one per student. Each was massively oversized compared to average guys, modeled after Oppa's cock. No match for the real thing, but perfect for practice.
"Huu... huung... ♥ Today's lesson is cowgirl practice. Cowgirl means the onahole mounts up top to service the man's cock. The man doesn't have to move at all—he just relaxes and enjoys. Big plus. Since he's stationary, it's perfect for objectively judging our onahole skills. Downside? He won't seek out his own pleasure spots, so if we slack, his ecstasy halves. Gotta pay extreme attention. And one more thing... a huge caution. Anyone wanna guess?"
"Don't let getting on top go to your head. Cowgirl's just another service technique—don't act like you're something special and ruin the man's mood. That's the key."
"Spot on. Mira really knows her stuff."
The teacher praised her. Despite looking like she'd never cracked a book, Mira excelled in theory and practice—a model student who outshone even teachers in specialties.
Mira grinned smugly at Hyeonju, mouthing How's that? God, she was insufferable. Slut acting all high and mighty.
"Haa... haa... Then I'll demonstrate first, with the recommender's help..."
"Mm."
Oppa lay flat on the gym floor. The teacher, still connected pussy-to-cock, settled onto his crotch—back-facing cowgirl. Students formed a circle around them, eyes locked on the demo fuck.
"Watch closely. Basic postures split into back-facing and forward-facing. Forward lets you provide tit and face shows—super common for that reason. Back-facing hits spots tough in forward. Now for the grinding—pay attention."
After briefing the class, she slowly lifted her pussy, then sank back down, starting the grind. His pillar-stiff cock stayed put; her pussy alone bobbed up and down, washing it clean. Rough then soft, devouring it with shakes and squeezes—her pro-whore skills were pro-level.
"Cocks have personalities, but core pleasure spots aren't as varied as onahole ones. There's an optimal grind length. Still, personal tastes vary, so find the route tailored to each cock. Got it?"
"Yes!"
True to teacher form, she explained perfectly. Just jealous sex with a great cock? Sure. But fulfilling her role so diligently sparked admiration over envy.
Mid-grind, she glanced back, flashing Oppa a servile smile. "How is it? Does my pussy please you?"
"Oh, it's great. Teacher-worthy for sure. Only regret? Can't see your face properly."
"Ah, sorry. One moment..."
Apologizing to Oppa, she turned to the class. "Textbooks sometimes assume 'ignore onahole pleasure during service'—that's just for convenience, not reality. Truth's the opposite. Flaunt your ecstasy to stoke the man's conquest urge. It's not just about squeezing. Often, boosting his ego matters more. Burn that in. The textbook line warns against getting lost in your own pleasure and slacking service. Know the difference. Got it?"
"Yes!"
Even mid-fuck, she guided the next generation. Pointing out that common pitfall, she switched to forward-facing per Oppa's wish and resumed cowgirl service face-to-face. Soon, Oppa creampied her pussy with a refreshing blast. Her bitch-in-heat face on the verge of ascension? Iconic. Snapping back to teacher composure mid-orgasm? Also iconic.
"Now, practice time. Use those dildos—hit every cowgirl skill I showed. Got it?"
Suddenly, Oppa chimed in. "Plain practice is boring, so the best-behaved student with the top grind gets a creampie reward from me."
His words dropped, and the gym ignited into a battlefield of sparks.
