A Different Kind of Training (2)
Buuurrrr—!!! My cock trembled violently, like it was about to explode.
Ra-hee's eyes widened like they were about to split open as she had my cock in her mouth.
"Mmph, hnnngh—!!!?"
Seeming to sense something dangerous, she tried to yank her head back in a hurry. But my hands were clamped firmly on her head, making it impossible.
Twitch, twitch—!!
"Mmmph! Mmmphh—!!"
"Sorry, sis! I'm gonna cum!"
I'd tried to hold back, but I'd hit my limit. No matter how sorry I felt for Ra-hee, who was grimacing in agony, I couldn't fight the urge anymore. With my cock buried deep in her throat, I started unloading my semen.
-Spluuuurt—!!!
"Mmph, guuuuh…♡♡"
Ra-hee pounded my thighs with her fists in panic, but I ignored it and wrung every last drop into her throat. The sheer volume was like piss—you could almost call it that, aside from the thick consistency. I'd already blown a load at home, and here it was even more... Was it because her mouth felt so warm and good? Even I was shocked by the massive amount pouring out.
A cool, intense pleasure washed over my whole body, just like when you're finally pissing after holding it forever.
"Kehk…! Gulp, gulp♡♡"
At first, Ra-hee struggled like she was choking, but once I started cumming, her eyes took on that heart-eyed look as she began gulping it down.
A moment later, when I finally released her head, she threw it back and gasped for air.
"Cough! Cough!"
White liquid dribbled from the corner of her mouth, which she'd failed to swallow completely, trickling down into her cleavage and onto her sports bra. Seeing that made my cock twitch again.
"Y-you okay, sis?"
"Hey! What the hell, pressing my head like that? I almost suffocated!"
"Ow! Sorry!"
She kicked me with her foot, tears welling in her eyes, so I apologized in a panic. Wiping them away with the back of her hand, she shot me a glare.
"And why'd you cum so fast? How am I supposed to train you properly like this?"
"Train…? Oh, sex training, right?"
"Yeah. You cum once, so you won't get hard again, right?"
Of course she'd think that. Normal guys hit their wise man phase after one load and call it quits. But that didn't apply to me.
"I can cum again, though?"
Throb—
"Wha…?"
Ra-hee's eyes went wide as my cock showed signs of getting hard again.
"…For real? You can get it up again?"
"Yeah. I might suck at stamina, but my libido's top-notch."
Maybe because of how intensely she'd sucked me off, my dick wasn't going soft—in fact, it swelled even harder than before, pointing straight at her.
"What next? I still don't really get sex training…"
"Huh? Oh, right! I'll show you!"
Her expression flipped in an instant. Flashing a smile that matched her pretty face, she kicked off her sneakers and socks, stepping barefoot onto the mat.
"Se-hyeon, you ever done sex training before?"
"N-no? First time."
"Got it. Guess I gotta teach you properly, then?"
With that, she hooked her thumbs into her leggings and panties, slowly peeling them down together like she was putting on a show. I just stared blankly.
I'd kinda expected things to go this way, but seeing her pristine white skin and that pussy emerge left me dumbstruck, leaking a stupid groan.
A p-pink pussy…!
Not a single hair. And so damn white.
"Any position you wanna try?"
"Uh, whatever? I'm good with anything."
"Hmm… How about this one?"
She got on all fours on the mat and stuck her ass out toward me.

The so-called doggy style. Her backside, now free of those skin-tight leggings and baring her pale flesh, was way more tantalizing than the glimpses I'd stolen at the gym before. And…
P-pink…!
Both her pussy and asshole were pink. Her skin was so fair that the color popped vividly, looking even prettier by contrast.
Sensing my stare boring into her from behind, Ra-hee smirked and hiked her ass higher, giving me a perfect view of both holes.
Drip, driiip—♡
"Ah…."
The moment I saw the thick, sticky fluid leaking from that pink slit, my mind went blank. No thoughts, just white noise. Super viscous love juices trailed down her thighs, and a lewd scent hit my nose.
The smell of a bitch in heat… Drawn in by that sticky, obscene aroma, I edged closer to her ass. She gave me a flirty eye-smile.
"Now shove your cock in whatever hole you want."
Wh-whatever hole? I swallowed hard, eyes dropping lower. Between her snowy cheeks, two pink holes winked at me invitingly, twitching.
"A-anywhere's fine?"
"Yup. Pick a hole."
I hesitated for a second. Just go for the ass? Nah, I shook my head.
First time's gotta be pussy.
I wasn't big on sentimental stuff, but pussy felt right for the debut. Decision made, I took a deep breath and slowly pushed my cock into Ra-hee's pussy.
Squish…
"Ngh…!!"
I figured it'd feel good, but her insides were way hotter, stickier, and tighter than I'd imagined. The thrill of finally doing what I'd only seen in porn—with idol-level hottie Ra-hee—sent electric excitement surging through me.
Squelch—♡
"Sis. This sex training really works on cocks, right?"
"Hnn, ahh… Of course…♡ Fixes premature ejaculation… Keeps you hard longer…♡ Don't stop—just ram that dick in. I'll squeeze your cock nice with my pussy♡"
"Got it…."
I slammed it all the way in, as ordered.
"Haaaah…♡"
Ra-hee moaned in ecstasy as my cock plunged deep. Once it was buried to the hilt, the stimulating bumps and folds inside her pussy started massaging it just right.
"Haaah… Your cock's so hard…♡"
She shivered in satisfaction. I panted from behind her.
Fuck, this is hot as hell…
A sweet, thick scent teased my nose. It was her body odor wafting from her whole frame—sweet and intoxicating. Sweat beaded on her pale skin, glistening under the lights and making her even more alluring. Those sweat droplets were mixing into that dizzying aroma hitting my nostrils.
-Squelch…
"Ngh, ahh…♡ Move faster… That's how you train the cock…♡"
Her cheeks flushed lewdly as she wiggled her ass teasingly. Her asshole twitched between those sweat-slick cheeks—insanely hot.
"Yeah… Here I go."
Squish, squelch♡
As I started thrusting, sticky sounds echoed from our crotches. Ra-hee's juices were plentiful… and thicker than expected. As I rocked my hips slowly, I noticed other gym-goers glancing our way one by one.
But the looks didn't linger. People were openly fucking in the gym, yet no one batted an eye. It was just normal. Most flicked a glance then went back to their workouts.
Seeing that, I started pounding Ra-hee's pussy with gusto, like I was showing off.
-Plap! Plap! Squelch!
Soon, the slap of flesh on flesh drowned out the gym's clanging weights.
"Haa, haaah♡"
"Hoo… Ngh…!"
As we fucked hard in the middle of the gym, relentlessly drilling her pussy from behind, I felt the urge to cum building.
"S-sis! I'm gonna cum!"
"Hold it…! Thirty more thrusts…♡!"
"Th-thirty!?"
Way too harsh for me. I was on the verge already, and she tossed out "thirty" like it was just reps on squats.
"Hoo…!"
But I decided to obey. This was sex training, after all.
And no premature cumming…!
First time or not, I didn't wanna blow alone and end it pathetically.
"Okay. I'll try to last…!!"
Gripping her ass to endure the pussy's crushing grip, I started pumping for those 30 pistons.
