1.
"So, what should we do first?"
Deneb placed her hands on her hips and declared.
Her nightgown folded to either side like fairy wings, parting in the middle to reveal a glimpse of her long, slender navel.
It was pajamas with exposure levels too high even for broadcast dramas.
Yet despite showing off so much skin, not a trace of embarrassment crossed Deneb's face.
Differences in perception turn the same experience into wildly different emotions.
Take a man entering the women's bath, for instance. Holding his mom's hand at age four is one thing; barging in after discovering sex is another entirely, right?
For Deneb, male-female relations or sexual taboos were distant abstractions.
To her, this task was just an extension of some quirky magic experiment.
To Siwoo, on the other hand, the situation was utterly mortifying and awkward.
No matter how they dressed it up as "magic research," it boiled down to a lewd exploration of his mother-in-law's body...
"......"
The bizarre disconnect from their clashing perspectives left Siwoo speechless. Deneb spread three fingers and proclaimed:
"Don't even think about rushing through this. Tonight's experiment will dissect every step—insertion, thrusting, ejaculation—the works."
"Oh, Deneb..."
Albireo couldn't hide her embarrassment at the blunt objectives and covered her face with her palms.
Siwoo felt much the same, even if he didn't voice it.
It was the slow, sinking realization of an unreal scenario turning inescapably real.
Anyone who's woken up on day two of boot camp would get it.
"Then..."
His voice cracking with bewilderment, Siwoo cleared his throat and pressed on.
"First, you'll need to get on all fours here."
Siwoo gestured to Deneb's bed.
A slight bend or a pillow under the waist would make missionary workable enough.
But saying it to her face felt wrong on too many levels.
He'd planned to grit his teeth, close his eyes, and power through doggy-style.
"...On all fours? Why me?"
"No..."
"You want me crawling around like beasts in heat?"
"......"
Sex at zero favorability and intimacy was this brutal.
Even more absurd: Albireo egging on Deneb's wild misunderstanding from the sidelines.
"Siwoo, fussing over positions even now is a little..."
"No, that's not it!"
"Do it normally. That pose is too degrading."
Directly testing the backdoor isn't degrading? The retort burned in his throat.
He had no clue what they considered "normal."
Couldn't exactly launch into a lecture on anal sex positions here. He was losing his mind.
"...Then I'll defer to Lady Deneb's judgment."
"That might be best. Lie down there."
Frustrated by Siwoo's hesitance, Deneb seemed set on taking charge herself.
As he settled his head on the pillow, Deneb's cozy body scent rose from the bedding.
She crawled onto the bed awkwardly, then untied his gown's waistband.
A shower robe offered little protection to begin with.
Her fingertips hesitated briefly before parting the folds, exposing Siwoo's limp member.
For a split second, Deneb swallowed hard.
It was her first time seeing a penis up close like this.
"We'll need lube first, right?"
She produced a vial of pre-prepared scented oil.
The rear entrance produced almost no natural fluids beyond trace secretions, making lubrication essential.
This premium whale-oil perfume would outperform any modern gel—spot on.
Deneb dumped half the bottle straight onto Siwoo's dick, no restraint in sight.
Soon, a cloyingly sweet fragrance billowed from his crotch, strong enough to give him a headache.
She kneaded it like tossing a bizarre sea creature in sesame oil.
Life experience gave her the basics: get it hard before insertion.
But no matter how clumsily she worked it, it wouldn't budge past semi-erect.
Sensing something off, Deneb asked:
"Is this fully erect? The texts say it gets rock-hard."
"Doesn't look like it..."
Albireo—who'd glimpsed Siwoo with the twins before—tilted her head too.
Back then, even in silhouette, it'd been a rigid, girthy spear.
Now? Like an eggplant baked soft and slicked in oil.
Siwoo had his reasons, though.
Psychogenic ED accounted for most cases in guys his age.
Even with a beauty like Deneb stroking him personally, nothing stirred.
Because if he summed up today in one diary entry: 'Deflowered virgin little mother-in-law's backdoor—in front of big mother-in-law with zero guy experience.'
Utterly ridiculous.
Clueless, Deneb prodded:
"Hurry up and get erect."
"It's not like flipping a switch..."
"Siwoo, there's a saying: better to take the first hit when selling a cow. Let's wrap this up."
"Huh... I'll give it a shot."
No dodging this anyway.
Siwoo shut his eyes and unleashed full-focus erection breathing.
A secret art pooling blood into the corpora cavernosa from every happy synaptic memory.
Fueled by desperate fantasy, it swelled massively.
The impossible growth drew wide eyes from Deneb.
"It's... it's working."
Way bigger than expected... She feigned composure.
First time stuffing anything back there.
Couldn't fully gauge the pain, but this size scraped by as tolerable.
Confidence surged.
"Hmm..."
Albireo still eyed his junk suspiciously.
Even his trump card left it not-quite-rigid, not-flaccid. Classic semi.
The sisters lacked the know-how to call it out, so it slid by.
"Putting it in."
Deneb crawled between his legs and squatted down.
The gown split with the motion, baring her smooth sternum.
One issue, though.
"Uh... you'll need to take off your clothes..."
Her crotch was still shielded by panties.
The slit peeked temptingly, sure—but insertion through underwear? No dice.
"Think I'm an idiot? You don't need to see everything."
Deneb huffed primly and gripped his shaft.
Slim fingers coiled slickly around it, lube doing its job.
The glans tip met bumpy texture—Deneb's rear entrance.
Likely just snipped the back of her panties.
"Ugh...!"
The unexpected scorching heat from her hole made Deneb flinch and tense.
Albireo—who'd been tossing in quips—went silent, riveted.
He felt like a living dildo in this weird setup.
Female-superior anal for her first time? No walk in the park.
Especially with his half-floppy state—it kept slipping at the dock, sliding down her crack instead.
"Why won't it go in?"
Already grossed out by the soft-thing-rubbing sensation, now failing the goal too.
Deneb's brows knit in frustration.
"Does this even fit?"
"Yeah, it does, but..."
"I'll do it then."
"Sis, stay put."
Snapping back at Albireo's jab, Deneb grunted away in her squat.
Shocking enough to outdo any trashy K-drama.
But dicks don't lie, situation be damned.
Persistent stimulation had it stiffening, thickening in her grip.
"Huh? Huh? Huh?"
Like a molting larva ballooning into a hardening pupa.
After ages of struggle, Deneb glanced down at what she held.
"Wh-what's happening?"
"Oh my..."
"It's fully erect now..."
Confirming the monstrous rod—at least double its starting size—Deneb gaped.
No more softness.
Rock-solid.
Veins throbbed with powerful pulses.
Siwoo's cock was no longer some odd critter—it was a beast.
"This is really supposed to go in...?"
First time beholding such majesty, the doubt was inevitable.
Deneb stared, eyes trembling.
Albireo mirrored her shock.
Neither had dreamed it'd balloon like this.
"No reason it can't."
But Deneb's maternal instinct for the twins ran deeper.
She steeled herself for the ordeal.
Her hand gripped the shaft firmly.
Target: that perpetually slippery hole.
As she lowered slowly, the glans pressed hard against it.
"Hoo... hoo... hoo..."
Instinct guiding her, Deneb deep-breathed to relax.
The unyielding entrance, pressed flush by the glans, began to yield bit by bit.
"Hng...! Hn...!"
"Deneb! You okay? Loosen up more."
"You think it's this easy to watch?"
Her little sister sweated buckets, inching it in glacially; big sis fretted and backseat-drove.
No foreplay, no prep—swallowing Siwoo's monster raw was borderline self-flagellation.
Siwoo had wanted prone position for gradual buildup...
"Hng...! Haaa...!"
Pain overload or squat-strain locked her thighs tighter than with the twins even.
"Kuh...!"
Like jamming an undersized ring onto a massive finger.
Not even half the glans in, and failure felt certain.
"Deneb, why not let Siwoo handle it?"
Finally intervening, Albireo prompted Deneb's surrender.
She knew it was futile like this.
Ass throbbing, she sat primly legs-together and grumbled:
"Hoo, fine. You give it a try."
