Filial Piety (3)
I smirked inwardly as I watched Mom's flushed face. What on earth could she be thinking right now? Was she regretting her words about holding back? Or did she feel disappointed that I'd accepted them without a shred of hesitation? Either way, it was nothing but delightful to me. So, at least until Mom came crawling into my bed first, spread her legs wide on her own, and begged me to touch her—to shove into her roughly. Until then, I intended to play the perfect role of the good, innocent son.
Mom's pupils trembled minutely, like there was an earthquake in her eyes. Her lips twitched as if she wanted to say something, but in the end, she bit down hard and turned away.
Chae-eun scooped up a bit of soup with the ladle to test it, but she couldn't taste a thing. No, she couldn't even swallow properly. Her mind was entirely consumed by her son sitting right behind her. The pure, oblivious son. Was it okay to deceive him just to satisfy her own dark, filthy desires?
Unfortunately, it wasn't that kind of torment. Her pussy was already surging with hot juices just from the sight of him. If she hadn't been wearing thick clothes, it would've been obvious by now—it was that soaked. She wasn't even aware of it herself, and her hips swayed ever so gently.
She rubbed her trembling hands on her apron and bowed her head. Beads of sweat formed along her lowered nape.
She finally couldn't hold back and was about to say something when her two daughters emerged from their rooms, yawning lazily.
In the end, Chae-eun had no choice but to swallow the words hovering on the tip of her tongue.
"Mom. Food—!"
"I'm starving."
Seo-yoon, my older sister, and Da-yeon, my younger sister, shuffled into the living room looking disheveled.
"Yes, come sit down."
Mom set the side dish bowls on the table. I pretended to help, taking the bowls from her and letting our hands brush.
Zap—
"Ah...!"
Mom flinched and yanked her hand back. I asked her coolly,
"Huh, Mom? You okay? Static electricity?"
"Uh, yeah... I guess. Siwoo's hand is... too hot."
Her last words were barely a whisper.
During our late breakfast, I snuck glances at my terminal. Naturally, the app's functions went far beyond just tweaking numerical values for libido, morality, ethics, and self-control. Dive into the libido section, and there were subcategories: the kind that could be relieved through solo masturbation, and the kind that only the administrator could satisfy. I could fine-tune those even further on my own whim.
The moment I discovered that, I cranked the gap between them to absurd levels. If the pleasure from masturbating alone was a 2, then doing it while thinking of me jumped to a 5. And when I touched her instead? 10. Hell, I set it to 20.
A nearly tenfold difference. How long could she hold out? She wouldn't cave and slip into my bed after just one day, would she? I wanted more varied, desperate reactions, so I hoped she'd fight it hard. Sure, I'd have to play celibate in the meantime, but luckily, I already had a perfectly good hole for relief—Ju-hee. She'd told me to come anytime, no pressure. I could just vent there as needed.
Seo-yoon plopped down at the table casually, spreading her legs wide. Her white inner thighs gleamed through her short dolphin pants. Da-yeon, in her baggy tank top, stretched with her arms up, her breast outlines on full, unfiltered display. What used to be pixelated blobs thanks to the chip now appeared crystal clear to my eyes. I savored the view leisurely while placing some rolled omelet on Mom's rice bowl.
"Mom, eat up. You must be exhausted from the move yesterday."
My gentle, low voice tickled her ear.
"...Yeah, thanks. Son."
She picked up her chopsticks, but her hand still trembled faintly. Head bowed, she shoveled rice into her mouth, but her gaze kept flicking to my neck and forearms like a magnet. Throughout the meal, her thighs rubbed together ceaselessly under the table. I could almost hear the slick schlick, schlick of her growing wetness. Her toes curled tight.
As the bowls emptied, Mom shot me a sly glance and broached the subject.
"Siwoo, could you help tidy the backyard shed later? There's still some of Dad's old stuff left..."
She forced the words out.
"Of course. Gotta help out."
I grinned back. Whether she actually needed the help or had ulterior motives, either way promised fun.
The shed in the yard where I'd found Grandfather's terminal. I'd tidied it somewhat yesterday, but there was just too much—way beyond what one day solo could handle.
The shed door creaked open. At least the all-day airing had cut down on the dust smell.
Mom stepped in first, hand on her cheek as she looked around.
"...It is pretty hot in here."
She wiped sweat from her forehead with her sleeve and ventured deeper. Her thin cotton tee clung to her back from the sweat, tracing her spine perfectly. Every movement made her heavy breasts sway and jiggle.
"Siwoo. I'll unpack Dad's stuff, so could you grab that box from on top of the cabinet?"
"Sure."
I answered flatly and started shifting the worn boxes. In the cramped space, our arms and shoulders brushed with every move. How many times did it happen? While I was squatting to sort trash, Mom backed right into my head with her ass.
"Oof."
"Ah... sorry, Siwoo. The shed's too narrow..."
She jerked forward and turned, but her ears were already flushed red as apples. She was desperately telling herself it was just the stuffy air in this dim shed. But her body was brutally honest. After that, she kept "accidentally" pressing against me over and over.
And then, as if she couldn't take it anymore:
"Son. Can you get that box up there? I cleared the bottom."
"Sure."
It was on a high shelf. I climbed onto the stool, went up on tiptoes, and reached. The motion hiked my tee up, baring my torso. Mom stared blankly, then sidled up behind me under the pretense of helping.
"Uh, Mom'll steady you."
Her hand on my waist, her breasts hovering just shy of pressing into my ass. Her son's sweaty scent seeped straight into her brain.
"Haa..."
A thin breath escaped Chae-eun's lips. She instinctively leaned forward to press her chest against me, but some faint shred of morality made her jolt back in shock. I set the box down, and Mom fanned her face, panting.
"Siwoo... I think I'll step out and rest. Getting dizzy all of a sudden from the heat..."
"You sure? Here, I'll help you."
I wrapped an arm around her waist under the guise of support and pulled her in tight.
Grab—
"Eek...♥"
Just holding her waist made her whole body shudder like a convulsion. Her scorching heat radiated through the damp fabric.
"Si-Siwwoo... hand, your hand..."
"You're dizzy, right? Gotta be careful."
I gripped her waist even firmer on purpose, pressing her head to my chest. She could've shoved me off easily, but her lips just quivered for a moment.
"Y-Yeah... careful... Guess I'll lean on my son, then?"
A faint smile crossed her face as she surrendered her body to me. The app-amplified libido flooded her mind with lewd fantasies, while her slashed ethics and restraint let her rationalize it as just her son helping out.
Her breaths in my arms grew sticky and feverish.
"Haa, haa..."
They were morphing into animalistic pants. Her stiff nipples poked prominently through the thin tee, zapping against my body. I kept my hand firm on her waist and leaned down to whisper hotly in her ear.
"Mom, your body's burning up. You sure you're not actually sick?"
"N-No... just, just hot... haaang♥"
My voice tickled her ear, and her legs buckled, dumping her weight into me. If I'd dragged her to a room right then and stripped her while holding her, she'd probably have spread wide eagerly. But I didn't push further. Once we reached the entrance, I gently nudged her away and let go.
"Almost done here, so go rest outside. I'll handle the rest."
"...Huh? Oh, yeah... Thanks, son."
Chae-eun shuffled out like she'd been shooed. But that final backward glance before she left? It sure as hell wasn't a mother's eyes. It was the gaze of a ravenous bitch dying to turn back, bury her face in my crotch, and devour me.
I chuckled softly watching her unsteady retreat. I'd bet my life savings she'd race to her room and masturbate.
As Siwoo predicted, Chae-eun retreated straight to her room claiming she felt unwell, locked the door, and flopped onto the bed. Every second counted—she hastily shoved her pants down and tossed them on the floor.
Gritting her teeth, Chae-eun slipped her hand into her thin panties. The insane heat from every brush against Siwoo's body in the shed kept clawing at her lower belly. But no matter how she worked her fingers, the returning sensation was brutally dull and dry.
"Hngt... haaa... Why, why is this happening...?"

Chae-eun's face soured as she pouted and rubbed her pussy roughly. The wet squelching sounds were there, but the pleasure that should have slammed her brain was nowhere—just a pathetic, heartbreaking tingle, like grinding over thick clothes. Even solo yesterday had felt way better than this...
Schlick, schlick.Squelch—
"Ung... Hate it... this sucks...!"
She let out a frustrated moan and bucked her hips. Her body was flushed and soaked, but the spark at her fingertips fizzled into faint smoke and died. Suddenly, she recalled Siwoo's firm grip clamping her waist earlier that day in the shed—the thick, musky male scent numbing her nose, the searing warmth through his tee. Those mere brushes had felt so much better, happier, than this by orders of magnitude.
She let out a wistful sigh and squeezed her eyes shut.
"Ah... Siwoo... Siwoooo...♥"
The instant she uttered her son's name:
Zap—!
"...Ah, hngt... Ung?"
The faint sensation suddenly surged unmistakably up her spine. Chae-eun's eyes widened. Just calling his name did this much? Entranced, she murmured it again.
"Siwoo... my son...♥ Heek—♥"
She rubbed her pussy over her panties while chanting his name. An overwhelming wave of pleasure—nothing like before—crashed over her entire body.
