#13 Scenario: The Confused Pubescent Boy
"Slurp..., chuuup..., mmph...!"
His cock swelled in her mouth, on the verge of erupting at any second.
Determined not to miss a single drop of semen, she pressed her lips tighter against the glans and swept her tongue quickly over it.
"Nng..., Sis...."
With a short gasp, the hot, thick semen from his swollen shaft flooded her mouth.
It had a fishy tang at the tip of her nose, rolling over her tongue like lukewarm jelly.
"Mm...."
Even after taking all the cum that poured into her mouth, she kept licking to draw out every last bit remaining.
"Haaah...."
She looked up at him, and he was covering his eyes with his wrist, letting out a long sigh.
"Slurp...."
Finally, like a kiss, she sucked the last drop beading at the urethra into her mouth before lifting her head.
There was no tissue nearby, so she spat the semen onto her palm.
Gazing at the pool of cum in her hand, she marveled.
"So much...."
It was thick and filled her hand to the brim.
"Did it feel good?"
At Woo Da-hee's question, he shyly turned his head away.
"Y-Yeah, it did."
"Aww~, from now on, you gotta tell sis, okay? It's not weird for the women in the house to take care of your urges. No need to be embarrassed."
She spoke thoughtfully, considerate of his gruff but deep-hearted nature.
"......Got it."
She patted his thigh as he answered reluctantly.
"Sis peeled some fruit, so eat up and rest, alright?"
"......Yeah."
"Our Siu's such a good boy~."
"I'm not a kid."
Siu insisting he wasn't a kid anymore was so cute it drove her crazy.
She left the room so he could rest alone and headed to the bathroom.
Drip, splat.
The sticky semen clinging to her hand plopped into the toilet.
"......The smell's so intense...."
She had no memory of ever taking her husband's semen in her mouth.
He always came on her stomach or back, so she only vaguely remembered its faint scent.
Whoosh.
After washing her hands under the running water, she went back to the living room.
She lounged sideways on the sofa and searched her phone about pubescent boys.
"No other ways to get closer...."
It was something she'd have to ponder while Siu stayed here.
She closed the browser and, to kill some boredom, opened her photo gallery.
There were countless pictures with her husband.
Some from the gym during workouts, others with colleagues from her acting days.
"Hng~, brings back good memories."
Acting had been tough, and after marriage, her husband opposed it, so she hadn't done it since—but she understood, even if she felt a bit resentful.
"Hm?"
As she scrolled through photos with her husband, a strange sense of dissonance hit her.
A picture from the full villa, pressed close together.
Taken in swimsuits by the pool—it made her stomach drop.
"What is this...."
It was clearly a photo with her husband, but it felt off for some reason.
"......"
Vivid memories from that day with her sister and her partner replayed, starting the rationalization.
"Was it Siu...? Did Siu come along too...?"
She sat cross-legged on the sofa, rubbing her temples, but no answer came.
"Whatever."
It wasn't a weird photo anyway, and that wasn't what mattered now.
"Urgh~, guess I need a break too."
She opened the curtains she'd closed because of the breeze, revealing the apartment complex glowing with streetlights as the sun had set.
§
"Acting's tough."
Pulling off the pubescent boy act was no joke.
He tried recalling what he'd done at that age, but it was just hitting the PC bang after school.
"Even acting's no walk in the park."
The standoffish performance was hard. To her, he was her husband's cute little brother; to him, she was a friend's older sister, a married woman, and prime fuck material just a few years older.
"Next scenario time...."
Without the Scenario Book, he had to rely on memory.
He ran a mental simulation while thinking of the next scenario.
"Alright, done."
After finishing the sim, he massaged his spent cock, one foot still out.
"Must be from jerking off every day for scenarios."
His stamina and erection strength were improving day by day.
Maybe from draining his balls dry every scenario—he could feel the growth.
Rustle.
For the next scenario, he grabbed a towel and change of clothes and left the room.
Creeak.
Deliberately lightening his steps to play the considerate role for her.
He hung the towel in the bathroom, took a deep breath, then headed to the living room—empty.
"Must've gone to her room."
He headed straight for Woo Da-hee's room to find her.
§
Woo Da-hee.
She'd lain down to check her phone before washing up and dozed off.
Knock knock.
The knock on the door woke her.
"Hng, ha. Oh, I fell asleep...."
Rubbing her eyes, she got up and opened the door.
Seeing Siu standing there, she tilted her head.
"Hm? What's up~, our Siu?"
"Um.... How do I turn on the boiler?"
"Gonna wash up?"
He nodded slightly, and she patted his cheek before turning on the boiler from the controller in the master bedroom.
"There, all set. Sis was gonna wash up too but dozed off."
"Sorry for waking you."
"No worries~ Sis was gonna anyway."
As he turned to go wash up, he hesitated.
"Um, sister-in-law...."
"Again."
"Sorry, sis."
"That's better."
She didn't like how "sister-in-law" drew a line and felt distant, unlike when he called her "sis" as a kid.
Leaning against the door, she brushed back her bangs and asked.
"What is it, our Siu? Something to say?"
"Well.... It's hard again...."
She'd heard puberty meant strong urges, but she hadn't expected him to get erect again so soon.
Whoever his future girlfriend was, she'd need a high sex drive to handle Siu.
"Hng~, that so? Want sis to take care of it again?"
"Yeah.... Uh, or wanna wash together? I was gonna anyway."
It should feel awkward, but she could see his efforts to get closer.
With his personality, he'd mustered huge courage—adorable.
"Wanna wash with sis?"
"Kinda? Just... reminded me of washing with you before."
"Pfft, back in elementary school?"
"......Yeah."
Come to think of it, she remembered bathing him as a kid.
A fleeting doubt: even in upper elementary, did she? But more than that, it was a chance to bond, so she agreed.
"Sure, let's wash together after so long."
"Okay.... I'll go turn on the water first."
"Hm? I can come too."
"In that outfit?"
Oh right—she was in a dress to greet him.
She wore them often at home for comfort, but it probably looked dressed up to him.
His shyness was so cute.
The innocence of teens, huh.
"Got it~. Sis'll change and come."
"Okay."
She sent him to the bathroom first, then went to the dressing room for comfy clothes.
"Hng~, what to wear."
Lots of panties, but shorts might make him awkward even as family.
"Start mild...."
To get close, she needed to seem familiar first.
They'd strip to wash anyway, but still—she picked carefully.
"Safest bet...."
She threw on her husband's usual baggy workout clothes.
So loose from his training—might seem more casual.
She tied her hair back tightly into a ponytail with a band, checked her face at the vanity.
"This'll make me look like a comfy sis, right?"
Smiling to herself, determined to see her old affectionate little brother again, she headed to the bathroom.
"Siu-ya~, young master~, can I come in~?"
"Ah, yeah."
His echoing reply from inside.
Click.
Opening the door, she saw him filling the tub diligently.
"How's the temp?"
She opened with small talk to ease any awkwardness.
"Feels good like this."
"Yeah? Lemme check."
She padded quickly over the cold floor and tested the half-filled tub with her fingertips.
"Yep, perfect."
Arm draped over the tub edge, she turned to look at Siu.
"Our Siu did great. Big praise."
"......You used to say that when I was little. I'm grown now...."
His pouty sulk still had that childish vibe.
She chuckled, standing up.
"Missed washing with sis?"
As she spoke, she undid her ponytail band, held it in her mouth, and lifted her tank top.
Unhooked her bra in one go, placed it on the shelf.
"......"
Siu blushed at her bare upper body, embarrassed.
"Oh my, sis's naked body that embarrassing?"
To her, he was still just a little brother.
"......"
"You strip too, Siu. If you're shy, sis gets shy too."
"Okay...."
He stood, turned his back, and undressed.
Compared to her workout-serious husband, his body was childlike.
"Still grown a lot~."
Yet as a guy, there were slight curves on his back.
She patted it, then re-tied her ponytail with the band.
"Pants off~."
"Okay."
They both slipped off their pants side by side.
"Quick rinse before the tub."
She shut off the tub water and grabbed the showerhead.
Whoosh.
Warm water poured; she started wiping down Siu's body with her hands.
"Missed showering with sis?"
"Yeah, brings back memories...."
"But why the distance~? Makes sis sad."
"I'm an adult now too. Wanna act more mature."
Like a kid declaring I'm a grown-up!—adorable.
Smiling, she sprayed every corner, rubbing with her hands.
"Turn around."
"......"
She cleaned his front thoroughly too, gaze dropping—his cock throbbed erect again.
Body childish next to her husband, but down there? All man.
"......"
Since he called it a complex, she was careful not to show notice.
Showering his cock, she gripped it gently like an egg, twisting and stroking.
"Nng..., sis...."
Hot breaths escaped with each stroke.
Taller than her now, but his expressions and actions screamed teen.
She smiled and said,
"Pfft, our Siu's all grown up. Taller than sis now."
"......"
She caught his gaze on her breasts.
Relieving urges was one thing, but teaching him about women was an adult's duty.
"Wanna touch sis's tits? I take pretty good care of 'em."
"Ah, s-sorry, I won't look."
"Nah~, it's fine. Go on, touch."
Grabbing his wrist from stroking his cock, she guided it to her breast.
His hand awkwardly kneaded it.
Letting him, she kept stroking him.
"Hng."
His fingers brushed her nipple; she let out an unintended moan.
"Ahng...."
"Ah."
As he flinched to pull away, she grabbed his wrist again.
"Keep touching. When it feels good like you, sis moans too~."
"D-didn't know."
"No one taught you at home?"
He just gave an awkward smile.
Made sense—with their family's stoic vibe, probably not.
"Hng~, sis'll teach you everything from now on. Wanna get in the tub first?"
"Okay...."
She sent him into the tub first, rinsed herself thoroughly, then joined him.
Splash.
The half-full tub overflowed as they both entered.
They sat facing each other at opposite ends.
"Siu-ya, spread your legs."
He did, and she settled between them.
Without the water running, only droplets plinking down.
Drip.
Slosh.
A slight movement sent water spilling over.
"Brings back the old days, doesn't it?"
