Yuna Becomes My Pet Puppy
After somehow finishing cleaning the room, I flopped back onto the bed comfortably.
"Haaah... Cleaning is such a pain in the ass..."
I didn't know who was coming next, but it had taken about fifteen minutes to air out the room and tidy everything up before they arrived.
The remaining five minutes? I dashed to the bathroom and quickly jerked one out to calm my raging erection.
Knock knock knock.
The moment I lay down, I heard knocking from outside.
"Already? Come in!"
Slide.
The sliding door flew open the second I said it, and in came the next visitor.
"Oppa!!"
Yuna charged at me like a bullet from a gun.
She leaped right into the air and landed squarely on my bed in one go.
"Guh!"
To be precise, she landed right on top of me, where I was lying.
Yuna immediately snuggled into my side, curling up and purring like a cat.
"Hnn... Feels good..."
Was it because of the precedent set by the others?
Watching Yuna hug me gently and murmur how nice it felt made me suddenly think of Yuri noona, with her obsessive craze for me.
I really hoped Yuna wouldn't turn out the same...
Anyway, Yuna—who'd just graduated high school this year and was set to start university—had a smaller frame than most girls her age.
Maybe that's why her petite form looked especially cute.
Whenever she grinned like an idiot and begged to play with me, it felt like she hadn't changed a bit since she was little.
Naturally, I reached out and started stroking her head out of habit.
She flinched in surprise at first, then started rubbing her head against my hand.
I seriously wondered if Yuna had been a cat in her past life—her behavior was that feline.
We stayed like that for about ten minutes, her nuzzling her face all over my body. Mostly my arms, chest, stomach, and neck—thank god she stuck to the upper half, or I'd have been in serious trouble if she'd gone lower.
"Oppa..."
"Yeah...?"
Finally, after ten whole minutes, Yuna spoke up for the first time.
"Oppa... you're not going anywhere, right...?"
"Going? Where to?"
"Don't leave Yuna all alone..."
She looked up at me with a quivering voice, on the verge of tears.
Seeing Yuna still refusing to grow up, I decided it was time she faced reality. I told her,
"Yuna. Women have to get at least one artificial insemination pregnancy before they turn twenty-five once they become adults. You'll have a baby, and then you'll have no choice but to become independent..."
"No!!"
The word "independent" set her off—she clung to me tightly and threw a tantrum.
"No, no, no! Yuna can't live without oppa... Yuna wants to live with oppa forever... Without oppa, Yuna's heart feels all anxious... and weird thoughts keep popping up..."
I could only sigh.
A yandere noona and a mentally fragile little sister combined into one ultimate brocon duo...
My future didn't look too bright.
"Oppa... Even if I have a baby, we'll live together... Promise me. Promise you'll never leave Yuna."
"Yeah, yeah, got it."
"For real?! You promised, oppa! Heehee..."
My answer flipped her mood 180 degrees. The gloom vanished, replaced by bubbly Yuna right beside me.
She poked and prodded all over my body with her small, cute hands.
But whether by accident or on purpose, she soon touched somewhere she really shouldn't have.
Thwack.
"Huh...?"
As she swung her arm back, her elbow smacked right into the head of my dick.
Yuna jolted at the unfamiliar sensation and stared wide-eyed at my crotch.
Honestly, with her breasts pressed against my side while she groped me everywhere, my cock wasn't fully hard but definitely had some blood rushing in.
"Oppa... what's this...?"
Shit.
This was the one thing I didn't want her noticing.
Her chest was smooshed against me from the hug, and all her touching hadn't helped—my dick was semi-erect at best.
"No way... Oppa, is this because of me...?"
Yuna's expression shifted in an instant.
Her innocent face twisted into something sly, like a cunning fox.
"This is... an act of God...?!"
Before I could finish, she gripped my cock hard and wouldn't let go.
"You definitely... have to do whatever I want for the full hour... right?"
I was already regretting giving those tickets to them.
No logical comeback in sight, I just lay there speechless.
As I shut my mouth and dropped my gaze, Yuna giggled and started squeezing and releasing my dick rhythmically.
Under the banner of the "ticket," I couldn't do a damn thing. I decided to let it play out.
Shlick.
And just like that, instant regret again.
In a flash, Yuna yanked down my pants and underwear, freeing my straining cock.
It stood straight up toward the ceiling, more embarrassed than ever.
"You looked like it hurt, oppa... I'll make it better. Phew~"
She blew a puff of breath right on my cock.
The ticklish air made it twitch and leak a bit of precum.
"Ooh... It's big... So really big..."
Unlike Yuri noona, who was clueless about sex, Yuna seemed oddly knowledgeable.
"I saw this online. This is an 'erection,' right?"
"...Y-yeah."
"Nngh?! Ngh..."
I hadn't even done anything, but Yuna suddenly started twitching on her own.
Her face was in ecstasy, drool dribbling from her open mouth.
"Hii... What is this... First time feeling like this...♡"
I figured it out quick.
She must've seen stuff online about male genitals, but she was clueless about her own female ones.
Theory nerds are hopeless.
Nothing beats hands-on experience over book smarts.
I resolved to teach her properly with the time we had left.
I slid my hand behind her back and grabbed a firm handful of her left ass cheek.
"Hngh♡?!"
She yelped in shock at the sudden stimulation. I didn't stop, kneading her ass relentlessly.
"O-oppa...? Hnng♡ Stop... Haa♡"
"Nope. This is a matter of pride as your big brother. I can't let my little sister have me by the balls."
With my right hand, I shoved my thumb into her open mouth and turned her face toward me.
"Haa♡ Ahhaa♡"
A single tear rolled down her cheek.
Seeing that made even more blood rush to my cock.
Am I a sadist?
Tormenting my little sister had accidentally revealed my tastes.
I kept at it, toying with the inside of her mouth without mercy.
Pressing her tongue, probing every corner.
"Haaah♡ Ahegao♡"
Her mouth forced wide, she could barely speak properly.
"Listen up, Yuna. You said you don't wanna be apart from oppa, right?"
She nodded frantically.
"Then you gotta obey oppa, yeah?"
She rolled her eyes for a second, then slowly nodded.
I grinned wickedly and told her,
"Good girl. Listen close..."
"From now on, you're my pet."
Pet...?
I had no clue what oppa really wanted from me.
Sensing my confusion, he explained further.
"Simple. You're literally my pet. Everything you've been doing so far is basically pet behavior anyway. You cling to me, purr like crazy—what else could that be but a cat?"
C-cute...? He thinks Yuna's cute?
Hearing that from oppa short-circuited my brain.
Adrenaline surged, my body buzzing with excitement.
My breathing quickened.
"Haa♡ Haaah♡"
Oppa still had my mouth pried open, so drool started trickling out.
But who cared?
Knowing oppa found me cute wiped my mind blank.
He laid out his demands.
"I've always wanted a dog. But I have a fur allergy, so I couldn't have pets. So..."
He raised an eyebrow and asked,
"Be my one and only puppy, Yuna. Then I swear I'll stay by your side forever... Sound good...?"
By my side forever...
"Woof...♡"
Then I'd do anything for you, oppa♡
