Rule 20. Rio's final outfit inspection right before her date.
Rule 20. Rio's final outfit inspection right before her date.
"Oh come on, it's all soaked... These were the panties I was gonna wear on my date later..."
When Catalina flicked on the light, the public toilet finally regained its sight.
The moment Rio, having sprayed her juices everywhere nice and cool, shook off her skirt and stood up—
A legendary, utterly absurd three-way standoff began.
I bowed my head deeply and said,
"Miss, I'm sorry. Your panties were split open down there, so I just... couldn't help myself..."
But what could I do?
Rio's crotchless panties. And Catalina's bodysuit with just the crotch unzipped.
In the dark, the texture felt way too similar.
The more I thought about it, the more wronged I felt.
But even in this mess, there was no room for excuses.
A rights-less toilet demon like me had no choice but to grovel and apologize.
Because of this ridiculous situation, I ended up kneeling there with my dick rock-hard.
That's when I noticed Catalina, fidgeting restlessly just like me, in my line of sight.
Even that madwoman seemed ashamed of bumping into Rio since dawn, her face all wrinkled like her own pussy folds as she stared at the floor the whole time.
"I'm sorry... I was trying to train him first thing in the morning, and it just..."
Squeeze.
Rio grabbed and yanked Catalina's nipple poking through the latex, asking,

"Hmm, in that outfit? What kind of 'training' were you planning? How to handle a woman? Or punishment for breaking the rules?"
"Hngh... ♡."
I could see Catalina's fists clenching at Rio's heavily sarcastic question.
Her face looked pained, sure—but why was it flushing red, with juices leaking from under the zipper...?
And sure enough, in one hand, the feather she'd been poking my nose with was sticking out. Drip, drip.
"Ugh..."
Rio, flustered by the lake pooling on the floor, awkwardly let go with a forced smile.
Her massive cushions, pushed out by the elasticity, jiggled like an earthquake.
"...Whatever. I'll let it slide just this once. I wasn't planning to call the teacher today anyway."
"Th-thank you."
Rio, who'd been scolding Catalina with arms crossed, spun toward me with a grin.
"More importantly, Teacher—what do you think of my outfit? Does it suit me?"
The smug look from earlier was gone; she was back to her usual bright-smiling self.
"I can't really tell on my own if my senior will like it..."
Rio spread her arms and spun front and back, putting on a fashion show right in front of me.
A neat beige knit over her usual baggy shirt, paired with a short pink tennis skirt crisply pleated.
The vibrant yet luxurious fabric perfectly accentuated Rio's already superhuman figure.
And with the light makeup she rarely bothered with, plus her glossy hair straightened to shine—
Urgh!
That senior guy... I was starting to envy him like crazy.
That fucker... That fucker!!!
With a face handsome enough to snag any woman in the world, he had to be.
Otherwise, I'd curse this unfair world to hell.
My jealousy nearly made me drool, but I forced an awkward smile and gave her a thumbs-up.
"Perfect score, Miss Rio. That senior won't be able to resist loving you..."
"Really? Hearing that from you makes me feel so much better, hehe!"
Rio beamed excitedly, looking herself up and down for a good while. She seemed to love my verdict.
"Date time~♪ Date time~♫."
She hummed cheerfully, shaking her hips with glee.
My eyes kept drifting to those massive tits bouncing wildly, not even contained by the thick knit.
That's when I remembered Rio's tint-colored nipples from our nightly lovemaking, my dick throbbing hard—
Sneer.
Rio suddenly stopped dancing and stared right at me.
Like she'd thought of something fun, a mischievous grin spread across her face.
What now? That ominous look...
"So hey~ How were my panties?"
"P-panties?"
"Yeah, the wide-open ones you roughly licked all over earlier~."
"...It was so dark, I couldn't really see them properly..."
"Hmm~ You soaked them nice and wet, and now you're playing dumb? That's playing dirty, huh?"
That was the moment.
Whoosh!
"Ta-da~."
Rio lifted her skirt hem with both hands.

There, on her smooth thighs, a scrap of black fabric caught my eye.
The panties meant to guard a woman's precious parts were uselessly splayed open.
Revealing Rio's plump pussy lips, sticky fluids trickling out between them.
Throb—!
"Ooh~! Great reaction!"
Maybe because of the glimpse of red flesh through the slit—my already furious dick twitched even harder.
...Can't a guy hide his honest reactions sometimes? What a headache-inducing daughter she is.
"Anyway, since you soaked my victory panties, you gotta take responsibility, right? Hehe! Clean them gently with those rough hands of yours?"
...
How do I handle this clueless slut giggling away...?
Unable to withstand Rio's pressure, I grabbed some tissue with my handcuffed hands and brought it between her legs.
"Excuse me..."
As I reached between her thighs, Rio eagerly stuck out her ass like she'd been waiting.
I carefully wiped her juicy pussy lips.
Squish. Stroke, stroke.
Pressing the soft pink mucosa firmly with the tissue made her thighs twitch repeatedly.
"Hngh... ♡! Teacher, your touch... is so naughty..."
Drip...
"Ah... It's leaking again... What do I do?"
Haha... Rio gave an awkward, troubled smile.
No matter how much tissue I used, her premature pussy kept soaking everything.
No point wiping no matter how carefully.
Resigned, I set down the dripping tissue and spread her victory panties aside as wide as possible to keep them dry.
Then, gently tickling the moist slit with my fingers until she was satisfied.
Stroke, stroke.
Rio's expression melted into bliss, her face flushed beet red long ago.
"Hehe... See, Teacher? You're so good at handling women~."
The sour scent of Rio's love juices filling the bathroom.
If this really symbolized my growth, nine out of ten parts were thanks to this wild beauty.
...Should I be grateful?
I tilted my head in vague confusion, but seeing her innocent smile, it felt better to just let it go.
But if I kept getting misunderstood like this, it'd be a problem. I wasn't good at handling women in general—I just knew Rio well.
Stroke.
"Haa... ♡."
Liking my fingering, Rio hugged my head tight again, stroking my hair.
Warm and tender.
Her heart was surely with her senior, but still... it felt like I was loved.
That's when I was savoring what might be Rio's last cozy embrace—
Chill!
A sudden eerie shiver made me turn, and sure enough—
From behind, Catalina's murderous glare alternated between me and Rio.
Sometime ago, the metal ring in her hand rattled in her fist—the one that used to clamp my dick and deny my release.
"H-ha..."
Looks like after this happy time ended, an unavoidable natural disaster-level aftermath was coming.
###
Before Rio left the bathroom, she clung to my head regretfully and said,
"Alright, Teacher, I'm heading out now!"
I was gripping her plump ass with both hands, but I couldn't say a word.
I hated to see her go, but as a mere slave, there was nothing I could do.
In that awkward silence between us—
Catalina approached Rio, breaking the quiet.
"Miss, let me escort you to the village entrance—"
Whoosh.
Rio irritably flicked her hair and cut her off.
"No need. I can go alone."
Catalina looked crestfallen at Rio's haughty attitude.
Rio passed her without a care,
But then—
"Oh, right."
Like she'd remembered something, she paused and turned back to us.
"Catalina."
"Yes, Miss..."
"No calling Teacher today, so make sure you take good care of him so he doesn't get lonely, got it?"
...
Wait, Rio? What the hell?
A chill ran down my spine so hard my shoulders shook. I sneaked a glance back—and yep.
Catalina's near-dead expression was reviving with energy.
"Yes. I'll manage him thoroughly."
"...Haha, don't go too hard on him. Anyway, I'm off? Bye-bye, Teacher~."
That's not bye-bye...
If you say that and leave, I'm—
Clang.
My desperate hand reaching for Rio swiped empty air as the stall door slammed shut mercilessly.
......
In the brutal silence after Rio unknowingly left me behind, alone with Catalina in this space—now,
Step, step.
"...Hear that? The miss said to 'take good care' of you."
"...You won't kill me, right?"
Instead of answering, Catalina held out the small metal ring right in front of my eyes, flashing a madness-filled smile.
Please... go easy. Just a little easy, I beg...
