#13 Scenario: Pubescent Boys Are Confused
In just a few days, they'd fallen into this kind of relationship—all thanks to the Scenario Book.
Clink.
I waited behind Woo Da-hee, arms wrapped around her waist, as she finished up.
"All done~."
Woo Da-hee, having put the last side dish container in the fridge, sucked the sauce off her fingertips and turned to me with a smile.
I placed my hand on her waist and met her eyes.
"Our Siu's such a good boy, waiting so patiently for noona to finish."
"Pfft, I'm not a kid anymore. I can wait that much."
As I grumbled, Woo Da-hee grinned and patted my ass.
"Aww, there there. Good job. You're a big boy now~."
We traded playful banter, chuckling softly to ourselves.
"Alright, noona, I'll grab some clothes to change into."
"Okay~. I'll get mine too."
Everything was happening within the confines of Woo Da-hee's house.
We could've gone outside, but humanely speaking, January weather was way too cold.
Woo Da-hee.
Even as she gathered clothes to change into, laughter bubbled up.
When he was little, he'd been like a little brother with no age gap, but after puberty hit, seeing him avoid her had hurt a bit.
Still, having him back to his old spoiled self after just a few days felt heartwarming and joyful.
[Pubescent Boys Are Confused]
Just like the book said, the walls of a puberty-stricken boy were high due to his overflowing emotions, but once you got close, the bond lasted through time.
"They say if you get off on the wrong foot during puberty, it stays awkward forever... Glad that's not us."
Before heading out, she glanced at the book on her vanity.
"Figures a book made by experts would work so well."
No author was listed, but it must've been backed by plenty of research to make it to print.
"Noona~! When are you coming~?"
She stifled a laugh at Siu's whiny voice and headed to the bathroom with the tub.
"Coming now~."
Being called by him no longer felt awkward.
She entered the bathroom with her change of clothes; Siu was already filling the tub.
She patted his back and said,
"Look at you, handling everything so smoothly now."
In Woo Da-hee's memories, Siu was still that little kid.
The only downside was how fuzzy those childhood memories felt—focusing too hard brought a nauseating dissonance.
She had to let it go quickly.
Whoosh.
As water poured into the tub, she stripped off her clothes first.
She checked her body in the mirror before steam fogged it up.
No special diet, but daily workouts kept her toned and firm.
Genetics blessed her with plump, round breasts, a slim waist, and wide, flared hips—even she was satisfied.
"Time for Siu to get undressed too."
She checked the tub's water temperature for him.
Meanwhile, Siu stripped, showing off his lean, natural build.
His brother was toned from workouts and regular tanning, glowing bronze—Siu was the total opposite.
But that didn't make her dislike it.
If anything, his raw, unpolished body felt cuter.
"Why don't you try working out, Siu?"
"Uh... school starts soon..., no, I was thinking of starting when high school begins."
"Pfft, aiming for college already?"
She covered her mouth, giggling at his slip-up with "semester starts."
"Erm... maybe a little?"
Siu was getting better at playful comebacks now.
She tapped his shoulders, then grabbed the showerhead.
"Let's wash up before getting in the tub."
"Yep."
Woo Da-hee wet him down with comfortably warm water.
The bathroom wasn't tiny, but with two people, it felt snug.
"Noona, wash me too. It's been a while."
"Hng~, like when you were little?"
"Yep."
She'd bathed him sometimes back then, so nostalgia softened her smile as she lathered him up with the showerhead and her hands.
Spraying water over him, her eyes landed on his cock—and she had to admire it.
'Whoa, even soft, it's huge...'
Lately, his cock wouldn't leave her mind.
The smell, shape, heat.
And the lingering shivers when he came inside—those memories kept sparking naughty thoughts.
She was supposed to relieve his urges, yet here she was getting aroused—embarrassing.
"......"
On her knees washing his legs, that dangling cock kept swinging into view.
No matter how many times she saw it, the girth was jaw-dropping.
Not even hard yet, but so heavy and swinging—her heart raced again.
"Noona, wash here too."
Siu spread his legs, lifting his limp cock.
"Huh...? Oh."
Staring at his exposed balls, she gently cupped and massaged them.
Her pussy grew slick as it hardened and swelled in her hand.
Is this what [Strong Addictiveness] means?
"Ah, that feels good."
"Feels nice here?"
She'd been so mature these past days—no way could she let that slip.
She softly fondled his balls, then gripped his shaft, rinsing it.
Now rock-hard, it twitched right in her face.
"Noona."
"Y-yeah?"
"Should we get in the water?"
"Y-yeah."
She turned off the shower, and they slipped in—water overflowed, draining away.
"Bathing with noona feels amazing."
Even as he spoke, her eyes were glued to his cock underwater.
Once hooked, her gaze and thoughts fixated on it relentlessly.
It was worth the effort over these past few days.
Strongly addicted to my cock, her responses lagged by a second or two even when I spoke.
I savored it, casually making requests.
"It'd feel great if noona used her hand."
No need to rush inside. I relaxed in the warm water, enjoying her touch leisurely.
"Hng~, so hard~?"
I smiled back as she stroked my cock, laughing.
Arms spread wide, I basked in it.
Splash.
She started tentative, then shook it gently underwater after glancing at my face.
The sticky pleasure from my cock and her wriggling fingers loosened my body.
"Feels so relaxing and good when noona does it."
Lip service here and there boosted intimacy and immersion degree.
Once nicely mellowed, I stood.
Splash.
Water streamed off me. As I approached slowly, Woo Da-hee looked up.
"Want me to suck it?"
She already knew what to do without me saying.
"Yep."
I gripped my cock and fed it to her mouth. She parted her lips, sucking the swollen head while looking up.
Stroking her wet hair, curiosity struck.
"Noona, you do this for hyung too?"
Slurp... mm... "No. We don't bathe together~. And this is just for Siu."
The nuance implied it was puberty-related, but that wasn't the point.
She'd never done this for her husband—only me. Thrilling.
Slurp... schlop...
Watching her suck the head, I wondered what it'd be like if her common sense fully warped.
Anger? Shock? Any reaction would be fun.
"Mm... good..."
I focused on her tongue tip against my glans.
No matter how many times, getting off for free like this was peak luxury.
Grabbing her head with both hands, I slowly thrust.
Schlurp... mmph! Mmph...! Slurp...! Hng...! Glrk...!
My cock hit her throat; she squeezed her eyes shut, enduring.
"Noona, gonna cum in your mouth like this."
Slrp...! Mmph...! Glrk...! Mmph...! Glrk...! Schlop...!
Even then, she kept sucking to the base.
Thoroughly conditioned, oblivious to it.
Time to leverage that built-up addictiveness.
"Cumming..., noona...!"
I gripped her head tight, pounding like a fleshlight, unleashing the building load.
Teeth grazed occasionally, but pre-orgasm, it barely registered.
Spurt!
I filled her mouth to overflowing.
Spurt!
Shuddering repeatedly, I emptied fully before pulling back.
"Mmph...!"
Mouth clamped shut, cheeks puffed, she looked up.
Too deep? Tears welled in her eyes.
Flushed cheeks from the hot water made her irresistibly erotic.
Gulp!
Wincing one eyebrow, she swallowed my load and caught her breath.
"Ha..."
Her melting expression from my taste inside—despite cumming once, my cock sprang back hard.
Grinning, I pressed it to her nose.
"My scent's nice, right?"
"Mng? Anything from our Siu smells good~."
Even then, sweet words for me.
Chuckling, I nudged her lips; she resumed sucking the head.
Schlurp... mm...
Balls still tight, but I could go a few more rounds.
Pop.
I pulled from her sucking lips and rubbed it on her nose.
The musky scent dazed her mind.
Confirming her addiction, I stepped out of the tub on purpose.
"Shall we get out now?"
"Eh...?!"
She flinched, voice pitching high with disappointment.
"Guess we soaked too long..."
Helping her flustered self out, rinsing off—she wore that lingering regret.
Drying our wet bodies, I said,
"Noona, you look disappointed."
"Huh? Why?"
"You wanted me to cum inside?"
Towel around my neck, I sidled up, hugging her waist.
"Wh-what? I was just relieving your urges~."
Caught, she made hasty excuses—obvious, almost funny.
Holding her, I brushed her earlobe with my lips and whispered,
"If noona wants, I can do more..."
"You little~ getting so cheeky~."
She hugged back, smacking my back playfully.
"Mm... really? I thought you wanted it..."
"......I'm a grown-up~."
"No need for lies around me. If you want it, come to my room."
I released the hug.
Without looking back, I headed straight to my room.
Knowing she'd follow soon, I sat naked on the sofa bed, idly stroking my cock while waiting.
Woo Da-hee.
[If you want it, come to my room.]
Siu's parting words made her heart drop.
"......"
She knew it was wrong as an adult, but as she applied lotion, those words replayed.
"......"
Biting her lower lip in the chair.
"Am I... addicted...?"
Normally, no one would get this hooked.
Only one explanation left.
"Siu really has that... rare gene."
His cock's size and look were definitely not average.
"Then..."
She'd swallowed his cum countless times, taken it in her womb.
She gulped.
Mirror check: skin looked way better these past days.
"Freckles gone too..."
Even wrinkles seemed improved.
Waist fat had slimmed noticeably.
Once she thought it, everything felt enhanced.
"......"
Men make deals with devils for ambition; women for desire.
Greed stirred. Siu didn't know his own value yet.
"Just a little more, then..."
Gulping again, she stood naked.
The [Strong Addictiveness] warning flashed, but it was a flimsy barrier now.
Thud.
Naked, she walked to his door and knocked.
"Come in, noona."
Opening it, Siu lay on the sofa bed, still naked, scrolling his phone.
"You want it?"
"Noo~, just curious what you're up to."
He smirked, opening his arms and nodding.
"Lie down next to me."
"Should I~? Let's see how manly you've gotten~?"
She nestled her face on his arm, lying beside him.
He folded his hand, stroking her hair with a smile.
"Noona, if you suck here, I'll get hard again."
Guiding her head gently to his chest.
Feigning reluctance, she lay sideways and sucked his nipple.
Smack...
Leg draped over, she fondled his cock.
It swelled fast—her nipples hardened too.
"Sorry if you're doing this just for me when you don't want to."
Slurp... "Not at all."
"Then you want to do it with me? I can fuck you."
Saying she wanted it meant no turning back. But the answer was set.
"I want to..."
"Where do you want me to put it?"
He rolled, hugging her tight as he asked.
Siu, once a kid, now felt massively enveloping.
"Say it properly, or I won't."
Breaths mingling close.
"In my pussy... cum inside..."
"Noona, it's okay since I'm not your husband?"
She didn't even register calling his brother "husband."
"It's fine... I'm on the pill."
His serious face relaxed. Then he nibbled her earlobe, tickling whisper.
"Then I'll cum inside you all day today."
