애완누나(5)
Chae-eun hummed a little tune as she slowly approached her daughter from behind. With one hand, she roughly grabbed Seo-yoon's plump breasts, and with the other, she yanked her shoulder toward herself. Burying her nose in Seo-yoon's nape, Chae-eun took a deep breath.

"Snuuuurk. Haa... Your body reeks of Siwoo, doesn't it? Did my little girl sneak into her brother's bed and sleep there last night or something?"
Seo-yoon's shoulders twitched. She bit her lip, staring straight ahead without turning around. The memory of slipping into Siwoo's room at dawn and falling asleep in his arms flashed through her mind.
Chae-eun let out a low chuckle, savoring her daughter's reaction.
"Oh my, look at that face—you're totally busted. Wondering how I knew? Of course I did. Our son's the hottest, most incredible stud around. Once you get a whiff of him, you're hooked. Hell, if it weren't for you, I'd have done the exact same thing."
Saying that, Chae-eun dragged her tongue up her daughter's nape in a long lick. As the wet, hot sensation touched her skin, Seo-yoon let out a moan. Without stopping, Chae-eun shoved her tongue into the crevice of Seo-yoon's armpit, licking every corner to savor the taste.
"Haa, hnnngh! M-Mom... stop..."
Chae-eun nibbled her daughter's earlobe and laughed.
"That's a pretty tame 'stop' if you ask me."
"B-Because Siwoo..."
Seo-yoon desperately held out, obeying Siwoo's command to keep her hands clasped behind her head and stay still. Her legs were spread awkwardly wide, her hips thrust forward in a humiliating pose.
"Let's check out your pussy too, shall we? Gotta see if it's in good enough shape for our boy's cock. Wouldn't want him disappointed by something subpar."
Chae-eun reached her remaining hand between Seo-yoon's legs. Her fingers rubbed against her daughter's already sopping wet slit. Seo-yoon let out a scream-like moan, her hips bucking wildly.
"Hnnngh! N-Not there...!"
"What's wrong with it? It's already drooling like this. Does just thinking about Siwoo make your pussy twitch?"
Chae-eun shoved two fingers deep into the tight hole. Seo-yoon clenched her interlocked hands behind her head and barely kept her balance in her squat. Chae-eun pistoned her fingers in and out, scraping the walls like she was digging for gold. She rubbed Seo-yoon's clit hard with her thumb. Seo-yoon's eyes rolled back as she moaned wildly.
"Nnghoooo♥"
Seo-yoon stuck out her tongue and climaxed. Her body shook like a leaf, but she never let go of her hands behind her head. Satisfied, Chae-eun pulled her fingers out and gave her daughter's ass a sharp smack.
"You held up well. Might be a bit of a waste for Siwoo's cock, but... pass?"
The living room floor was soaked with Seo-yoon's juices. Just then, the bedroom door opened, and Siwoo strolled out slowly.
"Ah, there's my boy."
Chae-eun beamed and greeted him. She brought the hand that had been fingering Seo-yoon's pussy to her lips, lightly sucking the drenched fingers clean with a slurp. She winked at Siwoo.
"Mom got our Seo-yoon's pussy all soft and ready for you. Just shove it right in whenever."
Chae-eun crawled to Siwoo's feet. She opened her mouth and gently bit his pants zipper, slowly pulling it down. Then she grabbed his pants and underwear in her teeth, tugging them down together. Siwoo's springy cock popped out and slapped her cheek.
"Ah... Our boy's is always so impressive, no matter how many times I see it."
Chae-eun rubbed her cheek against his shaft, letting out a needy moan. She wanted to shove it in her mouth right then, but she turned to look at her trembling daughter, drenched in sweat and pussy juice. A loving mother's smile returned to Chae-eun's face—though the situation was utterly bizarre.
"Siwoo's cock is ready. Time for Seo-yoon to come over too, right?"
At those words, Seo-yoon approached Siwoo on shaking legs. He grabbed a fistful of her hair just as she tried to kneel before him.
"Did you pass Mom's inspection okay, sis?"
"Y-Yeah... Siwoo, she said I passed♥ Hurry, fuck me quick and make me your exclusive toy like Mom...♥"
Even with her hair gripped, Seo-yoon nodded eagerly, a dopey grin on her face.
"Good."
Siwoo lay back comfortably on the living room floor. Morning sunlight streamed through the window, highlighting his toned body. He nodded indifferently at Seo-yoon, who stood naked and shivering at his feet.
"Figure it out yourself, sis. I'll just lie here."
"Got it, Siwoo♥"
Seo-yoon crawled forward on all fours without even unclasp her hands from behind her head, just as he'd ordered. Her pussy, already a sloppy mess from Mom's fingers, hovered precariously over his cock. She struggled to line it up, but pleasure and nerves kept throwing off her hips.
Chae-eun, watching eagerly from behind, stepped in. She gripped Seo-yoon's waist with both hands.
"Oh dear, my girl can't even aim? Siwoo's waiting."
With expert hands, Chae-eun shifted her daughter's ass, pressing the entrance right against Siwoo's glans. The hot tip touched her, and Seo-yoon jolted like she'd been shocked.
"There. Don't wobble—just drop straight down. Like this!"
Without hesitation, Chae-eun slammed down on Seo-yoon's shoulders. Her virgin pussy swallowed his cock whole.
Squelch—
"Hnnngh!"
The brief resistance of her hymen gave way easily, and Seo-yoon's drenched pussy took him all the way inside.
"Haaah♥ I-It went in♥ Siwoo's cock is inside meee♥"
Seo-yoon's eyes rolled back, drool spilling from her mouth. The brain-melting pleasure dwarfed any masturbation or Mom's fingering—it wasn't even comparable. Her pussy walls clung tight and sticky to his shaft, molding perfectly to its shape as they squirmed and sucked.
Her body trembled as she moaned. "I-It feels weird...♥ Sex... is amaaazing...♥ Your cock's so haaard... and hooot...♥ It's throbbing inside me...♥"
Seo-yoon bounced her hips up and down. Her ass slapped against his pelvis. With her hands locked behind her head, her tits thrust out and jiggled wildly.
"Hoooh, hek...!"
His shaft emerged glistening with her juices. She swayed her thick ass side to side now.
"H-How's this... like thiiis...♥ Hnnngh...♥ Your cock's getting biiigger and haaarder...♥"
"Fuck... it's squeezing so tight."
Siwoo instinctively bucked his hips up, grabbing her pelvis. His glans battered the writhing walls that chewed on him like a living thing. Deeper and deeper until it kissed her cervix.
Squish—
"Hoo, hoooh♥"
Like a climax button, every prod at the entrance made her hips bounce and squirt. Her pussy entrance clamped down like it wanted to sever his root. Siwoo thrust harder, to the limit.
"Ah♥ Siwoo♥ S-Stop! Too deeeep... hnnngh, hoooong♥"
Her ass pressed flat against his abs. His glans ground hard against the cervix like it would pierce inside, sticky juices overflowing.
"Hiiiik—♥"
Overwhelmed, Seo-yoon wiggled her toes and twisted her waist to escape the pleasure. But that only ground her packed-full pussy around his cock in a twisting churn, rubbing her walls fiercely.
"Haaaang...♥"
Unable to hold out, she pitched forward, planting her hands on his chest for support.
"Hnnngh... hoooooght...♥"
"If you two just keep going at it, when's it my turn to cum?"
Chae-eun, completely forgotten by the pair, butted in. With playful eyes, she kneaded Seo-yoon's tits from behind and gripped her waist tight.
"Come on, Seo-yoon. Milk out Siwoo's load and get off already?"
She yanked her daughter's hips down, burying him deeper.
Squelch—
Her cervix ground against his glans, forced open.
"Siwoo's cock... is opening my baby room...♥"
Drool dripped from her gaping lips, splattering his chest.

Not satisfied, Chae-eun spun her daughter's waist in circles. The cervix rubbed his tip. His cock churned her insides relentlessly.
Slurp, slurp, slurp, slurp...
"Hoo, hoooooong♥ Nnghooooong♥"
Seo-yoon wailed like a beast, thrashing in ecstasy. His cock twitched wildly. Her pussy clenched in orgasm, but Chae-eun jerking her hips like a fleshlight doubled—no, tripled—the intensity. Having both sister and mom latched on to drain him was insanely arousing.
Semen pumped up from deep inside. Overcome, Siwoo pinned his glans to her cervix and unleashed.
Spurt, spluuurt—! Spluuuush—! Spurt—! Splurt—! Splurt—!
Cum blasted her womb walls. Her lips pursed shut, unable to even moan. She just threw her head back, body convulsing. Her ass lifted, twitching. Hot fluid jetted from her crotch like piss.
The ejaculation dragged on. Thanks to the chip mods, his stamina and load were boosted. More cum meant longer release—and prolonged bliss.
Seo-yoon's belly swelled taut with semen. Finally, it ended.
"Hnnngh, oguuugh... hrrk...♥"
"Okay, son. Time to pull out?"
Chae-eun lifted Seo-yoon's body slowly, extracting his cock.
Schlorp— pop!
Like uncorking a bottle, it sprang free with a cheerful sound.
"Nnghoook♥"
Splurt— splat—
Thick white cum bubbled out of her gaping hole.
"Huu... haa..."
His cock stood rigid despite the load. Siwoo glanced between it and his mom, nodding.
"What're you waiting for, Mom?"
Understanding, Chae-eun grinned brightly and took her son's cock—fresh from her daughter's pussy—into her mouth.
