Ninth Rule: Educating the Inexperienced Toilet About Women (2)
Ding-dong~.
Whoosh!
The moment I rang the bell at Rio's House, the door burst open and Rio flung herself into my arms.
“R-Rio miss?”
Squish.
The massive weight of her enormous breasts pressed plushly against my stomach.
Was it because she was only wearing a thin, sweat-soaked shirt? Her aroused pink nipples poked insistently through the translucent fabric, jabbing at my bare skin and asserting their presence.
Her disheveled blonde hair. Dark circles reaching down to her jawline, hollow eyes.
My cock, hidden in my pants, suddenly flared up at the sight of her so defenseless.
But right now, her exhausted state looked precarious, like a distress signal begging for rescue.
“Teacher... I feel like I'm gonna die.”
“...Did something happen at school?”
......
Rio miss didn't answer. Instead, she just clung to me tightly and reached into a drawer right by the door, pulling something out.
It was a key.
I stared at the key dangling and jingling from the ring, utterly confused. Then, with her face buried in my chest, Rio mumbled in a whisper.
“Teacher... promise you won't run away while you're staying with me. If you do, I'll make your hands feel so comfortable while you're here at home.”
Gulp.
Just that one thing, and these damn suffocating handcuffs would finally come off my wrists. My vision shook like there was an earthquake from the sheer anticipation of freedom.
Suddenly, Rio's hands gripped my shirt tight.
“Quick~, say it quick... I'm in a hurry.”
Hah... hah...
Rio stomped her feet, urging me on. Her heavy breathing made my heart pound wildly.
“...I promise.”
The moment I gave in to desire and nodded yes.
Clink, clank!
With nimble fingers, she unlocked the thick metal cuffs and tossed them to the floor.
Clang, thud!
The heavy iron chunk rattled the ground. But there was no time to savor the relief of liberation.
Leap, thump!
Rio grabbed my shoulders and jumped up, wrapping her legs around my waist like a koala.
As if to say don't you dare run. Her slim legs clamped down so tight that I could feel my cock pressing against her pussy through the fabric of my pants.
“Teacher... you can grab my ass... so just carry me to the bed like this.”
H-Her ass?
At the thought of clutching that plush ass as big as her chest, my fingertips started trembling.
But I pulled myself together, slid my hands down her dipped-in waist, and slowly brought them to that soft, squishy bare flesh.
As I teasingly placed my hands on her hot skin, Rio's arms—clinging desperately to my back—started slipping.
“Teacher... I feel like I'm slipping. Grab me quick~!”
Worried she'd fall, I urgently grabbed her ass to prevent disaster.
“Hngh♡...!”
My fingertips sank deep into her plush pussy flesh, and an orgasmic moan like a music box escaped her lips.
Smooth skin without a single thread in the way. For some reason, no panties touched my fingers on her drenched lower half.
“S-Sorry, miss!”
“...It's fine. Just... get to the bed quick...”
At her urging, I hurried inside. But her slick-with-juices ass kept slipping from my palms.
Especially when I boldly cupped the center between her legs for stability.
Squelch! Grip!
“Hnnngh♡!!!”
Like plugging a faucet, her thick pussy lips gushed juices that splattered across my hand with a hiss.
My hand was now slick with her pussy broth. Plus, her ass clenched tight, making her hips shake and balance even harder.
Every time her holy nectar dripped to the floor, she hugged me tighter.
Stifling sobs, she started grinding her soft pussy flesh against my bulging rough jeans.
“Teacher... just like this, a little... a little slower...”
She'd begged to hurry to bed earlier, and now she wanted slow? Her sudden childlike whimsy was absurd, but I couldn't complain to Rio, who was clumsily rubbing her pussy flesh with a trembling body.
She was savoring this moment, eyes newly opened to these sensations.
Step by step.
Ugh, my grip's giving out...
One foot at a time. Even moving steadily, my strength was reaching its limit.
Her body wasn't heavy. It was just that the handcuffs crushing my wrists had been replaced by handfuls of something else. Squish!
Still, I made it to the bed just in time.
I tossed her onto it without thinking, but the sinking mattress cradled her soft skin gently.
Between Rio's lewdly spread M-shaped legs, a smooth flesh-colored clam winked invitingly, stealing my gaze.
Her flawless thighs were quickly staining with her own juices.
“So hot...”
With feeble hands, she undid the buttons of her sweat-drenched shirt one by one. Each time, her massive breasts—compressed by the fabric—regained their shape bit by bit.
The threads that had wrapped her body parted wide. Atop those huge, round mountain peaks sat ripe berries, perfectly ready to eat.

What do I do? What the hell am I supposed to do now!
Rio was panting helplessly, in no mood to resist. Her hips twitched as if begging me to shove it in right now.
“Teacher, my pussy itches so bad... It's burning up, and I couldn't sleep a wink last night.”
She immediately covered her pussy mound with her hand.
No wonder she'd seemed off. Swallowing my cum last night must've set her ablaze.
“Tell me how to calm my pussy down...”
Hah, hah...
Her gravity-squished massive tits heaved up and down with each breath.
This is bad. How to calm a pussy? Like I'd know!
Pathetically, this burly cock of mine was brand-new, never once touched a woman's hole.
From the perspective of a 25-year virgin who'd only jerked off, I had no clue how to use a real pussy.
...Should I just shove my cock in?
The raging beast in my pants was thrashing, begging to be guided into her womb ASAP.
But ramming it in raw here was too risky. No condom, and boom—pregnancy. Hell, forcing this monster in blindly might hurt Rio.
“S-Sorry, miss. Truth is, I have zero experience with women too...”
Rio shot me a sharp glare.
She caught her breath for a long moment, pondering, then spread her pussy lips with her fingers and muttered.
“Then... like how I touched your cock yesterday, touch mine today...”
Between her fingers, pink petals spread wide. It was hard to believe this obscene, dripping cave belonged between a noble miss's legs.
Every hip twitch made the hole pucker like it was breathing. Deep inside, her cervix wriggled in her belly.
“It's embarrassing... don't stare so hard...”
“Y-Yes...”
Don't look at this precious sight gushing nectar right in front of me? Seeing her flushed face avert her eyes made my cock throb harder.
But teasing her more might piss her off.
Stroke.
I took her hand and gently caressed the slit between her pussy lips.
That instant.
Sploooosh!!! Sploooosh!!
Her pussy convulsed, spraying my face full of juices.
“Hnnnngh♡!! Teacher! My head feels weird!!”
Premature.
Her pussy was a squirting premature one that gushed at the slightest brush. Which meant even an inexperienced guy like me could satisfy her.
I quickly climbed onto the bed and leaned over her lying form.
Her tear-filled face, sleeve clenched in her teeth, drew close. Lying down, her face looked a bit different from standing, but she hadn't lost her goddess-like beauty.
If anything, her slightly scared sparkling eyes and quivering lips stirred my protective instincts.
A little lower, and our lips would meet. Realizing that, my reason started fading.
My supporting arms bent slowly. Still, her gaze stayed fixed on me.
But.
Smack.
Rio suddenly covered her mouth. She turned her head away, eyes dodging like she was sorry.
“Sorry. But my first kiss... I still want it to be with senpai.”
...Disappointing. Like letting prey slip from my grasp right in front of me.
It wasn't her fault, but frustration welled up anyway. As a slave, I couldn't force her.
Stroke.
“...Sorry.”
As I irritably tried to pull away from her embrace.
Grip.
Rio grabbed both my hands, stopping me.
“But below is okay... so... touch me... lots... touch me tons...”
Her teary downcast eyes reignited my cooled lust. Swallowed anger morphed into the instinct to conquer her.
“...You permitted it, miss.”
Whoosh!
I hugged her body with all my strength.
“Hahk♡!”
Rio moaned again, clamping her mouth shut.
I deeply stroked her sticky pussy slit once more. A lewd sound echoed from her sopping wet folds.
Squelch♡. Squelch♡.
The moment my fingers entered, her inner walls suckled them like a hungry baby bird. Slurp, slurp.
“Hng... Teacher, your hands are too big...”
Not missing a beat, I teased her pussy more boldly and deeply this time.
Squelch♡, squelch♡, squelch♡, squelch♡.
“Hyaaaaang♡!”
Rio screamed moan-like wails in time with my fingers relentlessly scraping her slit.
As I kept moving without pause.
Rio's eyes suddenly went wide.
“T-Teacher!! Stop... now!! If you keep moving like that, I-I'm gonna... cum... hnnnngh!!”
With desperate flailing arms and legs, she hugged my back as hard as she could.
“Hyaaaaaaaang♡!!”
