Rule Eighteen
Rule eighteen: For the jealous Ruby, a kiss brimming with warmth—as I pulled my cock out from Rio's precious place. Slick with her thick love juices, the condom slipped off with a wet pop.
Squelch.
The tip of the condom, bloated like a water balloon with my creamy white load, overflowed, coating my entire shaft in a milky haze.
I slipped my cock free from the slimy sheath, quickly knotted it, and tossed it toward the nearby trash can.
"Haa... haa..."
Rio lay sprawled on the bed, her face still flushed with ecstasy. My gaze drifted inevitably to the space between her legs, spread wide in an M-shape.
With each breath she took, her pussy—glazed with her juices—pulsed in rhythm, like it was breathing too.
But after my massive rod had churned her insides, the once-tight, prim folds were gone. Now, they hung limp and exhausted, exposing raw red flesh that steamed with lingering heat.
"...Ah, right—Sunbae!"
The moment she snapped out of her post-orgasm haze, Rio frantically searched for her phone.
She rummaged across the bed, spotted it on the floor, and dashed over. But as she bent down to grab it—
"...Ugh, my back... it hurts so much..."
Her torso halted abruptly, and gravity sent her enormous breasts into a wild, jiggling frenzy.
Watching the spectacle, my sage time hadn't even kicked in yet, but my cock was already twitching back to life.
Rio finally snatched her phone and checked her messages.
She stared at the screen intently for a long moment, then hugged it to her chest with sparkling, thrilled eyes.
She stood there, lost in the afterglow for a bit, before suddenly whipping her head toward me.
Whoosh!
She launched herself into my arms like a missile, wrapping me in a tight embrace.
"Teacher..."
"Yes, miss..."
"Teacher! Teacher!"
Rio clung to me with all her strength. She seemed absolutely delighted.
Then she brought her lips close to my ear and whispered,
"Thank you. If it weren't for you, I never could've gotten this far with sunbae... Thank you for being my practice partner all this time..."
With that, she planted a kiss on my cheek.
My hands instinctively drifted toward her ass, but—
"No way!! It's with sunbae! At a motel! A motel!!"
Seeing how excited she was about her sunbae—practically bouncing—I figured it was best to just hold her close. Our happy time together seemed to be drawing to a close.
...But don't most guys and girls head straight to a motel once they start dating?
Something about that sunbae guy rubbed me the wrong way, but as a total solo dude who'd only ever jerked off alone, what did I know?
Solo for life.
For some reason, it felt like a cool, badass term—like I was the type to emotionlessly plow through every woman in the world.
Thud, thud.
After Rio's declaration that she wouldn't need me anymore, I wandered the garden in a deep funk.
Suddenly, a voice from behind—cool yet gentle—called out.
"Something bad happen?"
I jumped and turned to see Ruby back on the bench, reading a book, wrapped head to toe in a thick, cozy-looking blanket.
...Right. Raven had told me to wait in the garden today.
I recalled our laundry room chat. Raven's tangy panties were safely tucked in my back pocket alongside Amelia's.
"N-no, nothing... haha."
"...Your face says otherwise."
...
Her eyes were on the book, but it felt like she could see right through me.
"...Miss, is your cold getting better?"
"Yeah. Not fully, but..."
Flip.
Thud.
Ruby suddenly closed her book and looked at me. Maybe it was timed perfectly, but snot started glistening from her dainty nose.

"It's cold... sniff..."
Even with a runny nose, how did her sculpted face never lose its glow?
Lost in the cinematic sight of her, Ruby blushed faintly and gently lifted half the blanket toward the bench.
So, this signal meant...
"You won't... hold me... like last time...?"
Her words embarrassed her; she averted her gaze.
In the end, Ruby climbed onto my lap just like before.
Her light weight settled on my thighs once more.
The difference? We were sharing the blanket she'd been wrapped in.
With only my handcuffed hands poking out, we shared our warmth.
Ruby clearly loved it, leaning into me with a drowsy, content face, eyes closed.
The blanket was a bit warmer than outside, but a faint chill emanated from her body, keeping it from getting too hot.
Using my shoulder as a pillow, her angelic face was right there up close.
Every time like this, I couldn't help but think: Ruby was adorable.
From afar, she had that prim, mature beauty like a cool beauty queen.
But when she peeked at me shyly through half-lidded eyes, it made me feel incredibly loved.
Waiting for me no matter how cold it was. Sneaking to my room despite the rules.
That subtly feisty attitude, despite appearances—it was drawing me in before I knew it.
"...So that's what happened with Rio."
Prodded by Ruby, I ended up spilling everything about today.
"Amazing... I never thought she'd take a liking to you like that."
"I didn't expect it either... It just kinda happened, haha."
I tried to play it off lightly, but could she hide her jealousy?
Ruby's pale cheeks seemed a tad puffier.
"Actually, Rio... was pretty against bringing you in at first."
"Really...?"
I recalled her face when I first arrived in Dia Village—wary, like I was worthless except for my dick.
"So when she broke the rules and came to see you, I was glad she forgave you easily... But now it feels like... she's stolen you away..."
A bit annoyed, she burrowed deeper into my chest.
Her head vanished under the blanket.
She nuzzled her nose into my chest, breathing deeply in and out. Then, as if she'd been waiting, she slipped her cold hand under my shirt.
Slide.
She twisted around under the blanket and looked up at me.
"...Did Rio smell like this?"
"M-my smell?"
"Yeah. Kinda tangy... like cheonggukjang..."
Cheonggukjang? Rio definitely smelled like peaches...
What the hell was that smell? As I pondered—
...!Chill!
A shiver ran down my spine.
There was only one thing on me that could smell tangy right now.
The week-old, fermented aroma wafting from Raven's panties, precious cargo in my back pocket.
Fearful Raven might be nearby, I glanced around frantically. Ruby tilted her head suspiciously.
Big trouble. I needed a solid excuse, fast, to defuse this.
The cozy blanket space, once filled with butterflies, now felt like an interrogation chamber.
Think... think, damn it!!
As I desperately brainstormed excuses with trembling eyes, forcing calm—
Swish.
A chill enveloped my body under the blanket.
Invisible, but I felt Ruby press right up against me.
Her face buried in my chest, she murmured softly,
"Sorry... Living in the Public Toilet must've been so tough, right?"
"...Huh? Oh, yeah..."
Unexpected, but... the suspicion seemed to fade.
Though guilt over my dishonesty weighed heavier now.
"I should've let you stay somewhere better... But the rules..."
What could I even say? Nothing felt right.
Probably because of the sweet floral scent from her hair stirring up complicated feelings.
I wrapped my arms tighter around her back under the blanket, holding her close.
"Haa..."
Ruby let out a trembling sigh and looked up at me.
Her cheeks faintly flushed. Eyes sparkling.
She seemed to love this moment.
"Hey... Can I... have a kiss?"
"A-a kiss?"
Caught off guard by the sudden request, but thinking of kissing this radiant ruby-haired beauty made my heart pound wildly.
"...So warm... Feels good..."
My racing heart heated up the blanket, and Ruby's eyes fluttered shut. Her small lips quivered.

Under the shared blanket, it felt like this was a special world just for us.
No man could pass this up. My mind was already filled with visions of ravaging her sticky mouth.
But... we weren't alone in this garden.
Somewhere in the bushes, Ruby's bodyguard Raven was surely watching me with hawk-like eyes.
Hesitating, Ruby cracked one eye open.
Seeing me glance around anxiously, she read my worry, closed her eyes again, and called out,
"Raven."
Rustle.
"...Yes, miss."
Sure enough, Raven sprang up from the nearby bushes, glaring at me.
"Turn around for a bit."
"...Understood."
Raven hesitated, glancing our way reluctantly, but turned as ordered.
Mwah!
Seizing the moment, Ruby boldly lifted her head. Her soft lips met mine.
Cool and plush to the touch.
But as her sweet, strawberry-tasting tongue slipped into me—
The warmth hidden in that chill burned hotter than anything.
