Father-Daughter 2.
"Hmm... you think so?" With trembling hands, I lifted my glass. Choi Seo-ah's toes were meticulously tracing the veins along my cock, stimulating it with precision. Her soft soles enveloped me completely, her toes moving with the delicacy of fingers.
"Cheers!" Department Head Choi Dong-jin clinked his glass happily. At that moment, her right foot began rapidly stroking my cock up and down. Her left foot gently massaged my balls at the same time.
"Ngh!" I swallowed the liquor while letting out a groan. Luckily, it must've sounded like the burn of the booze going down.
"Park, your face is all red. Is the stuff too strong?"
"Ah... yeah... it's pretty potent..."
Choi Seo-ah's toes zeroed in on the tip of my cock, teasing it relentlessly. Precum was already leaking out, wetting her toes. A memory flashed through my mind—that night I'd injected her with drugs and gotten her half-forced into a stupor. The feel of the piercings embedded all over her body under my fingertips. Especially that metal ball on her tongue when it licked my cock... the unique, stimulating sensation. Sorry, but with retrievers, there's always that lingering 1% disappointment. Like installing a top-tier 6090 GTI graphics card on a computer running Windows 94. Prime hardware wasted on shitty software.
"Oppa, have more snacks. You'll get wasted fast just pounding booze."
Choi Seo-ah said it with an innocent smile, but her feet grew bolder. Both soles wrapped around my cock fully, jerking me off like a hand—up and down.
"Ahh... yeah... thanks..." My voice cracked.
Her footwork was beyond imagination. Each toe pinpointed my sensitive spots with deadly accuracy. Whatever her deal was, she knew exactly how to seduce me.
"Our Seo-ah's so thoughtful. Look at her taking good care of Park."
Choi Dong-jin beamed proudly. He had no clue what his daughter was doing under the table.
"Of course, Dad. Oppa's an important guest."
Choi Seo-ah flashed a meaningful smile. At the same time, her toes grazed my urethra. The intense stimulation made my whole body shudder.
"Nngh..." A small moan slipped out. I chugged water to cover it.
"Park, you okay? Your face looks weird..."
"I-I'm... fine... just... a bit hot..."
Then Choi Dong-jin suddenly stood up.
"Ah, sorry. Gotta hit the john. Getting old means I gotta piss all the time."
"Sure, Dad. Take your time."
Choi Seo-ah smiled brightly. But her eyes gleamed with scheming intent.
As soon as Choi Dong-jin headed to the bathroom, Choi Seo-ah dove fully under the table.
"What the fuck are you doing? You nuts?"
"Shh... Dad'll be back soon. Lemme finish you off proper first. Gotta collect on that drug debt, right?"
She remembers me drugging her?
Her voice came from under the table. Then her hot lips touched my cock. A whole new level of stimulation compared to her feet.
"Fuck. It wasn't drugs—"
"Shh... no noise."
Her tongue started lapping at my cock. And right then, I felt the cold metal of her tongue piercing. The contrast of hot tongue and cold metal—same as a retriever so far.
"Mmm... Oppa's dick... still so huge..."
But the suction intensity kicked it up a notch. Slurp slurp schlop! Sluuuuurp! The warm, wet mouthfeel, plus her tongue piercing poking my sensitive spots relentlessly. Overwhelming pleasure no retriever could match—cum gathered at my tip.
"Wah-lah-lah-lah-lah-lah-lah!"
"Hng..."
I grabbed her head without thinking and shoved deeper. Plunge. Glug glug slurp slurp, grrrk.

Her head, bobbing back and forth, now moved up and down. The table shook; her passion was palpable. Powerful suction, tongue teasing nonstop, piercing rolling along my veins. Back when I first took her virginity, it wasn't really Choi Seo-ah anyway. I wondered what this entity wanted with me. Enemy... or ally...?
"Mmm... tastes even better than back then..."
Her technique grew fiercer. She took me deep into her throat. A tiny moan escaped her, but she didn't stop sucking.
"Glug... so... tasty... glug glug..."
"Mmm... mmm... Oppa... I really like you..."
She pulled off briefly and looked up. Her lips glistened; the silver ball on her tongue sparkled with saliva.
"That time... when Oppa first held me... I was so scared... but it felt so good too..."
"Choi Seo-ah... you—"
"So... I kept thinking of Oppa. Even with other guys... only Oppa..."
She engulfed me again, deeper, fiercer. Her piercing slid along the underside, sending electric shocks.
"Nngh..."
I felt climax approaching. My cock hardened more in her mouth.
"I'm... gonna..."
"Mmm... mmm... give it... I'll take all of Oppa's..."
She sped up, desperate for my release. Her piercing targeted my glans.
Then—the toilet flushed.
"Seo-ah... your dad's—"
But she didn't stop. If anything, more aggressive. The danger fueled her excitement.
"Mmm... mmm... quick... cum quick..."
The bathroom door opened. Footsteps approached.
"Nngh... mmm... mmm..."
Her final sprint. Piercing went wild in her mouth.
"Aaaah!"
I came. Hot semen erupted into her mouth. Spurt spurt splurt! Spluuurt!
"Glug glug glug. Gluuuurp!"
She swallowed every drop.
"Nngh!"
Choi Seo-ah moaned in satisfaction, her piercing rolling through the cum in her mouth.
"Seo-ah, whatcha doing?"
Choi Dong-jin's voice right behind us. She scrambled up, but...
"Ow!"
Her head banged the table edge. She got stuck halfway out.
"Huh? Seo-ah, why're you under the table?"
Her upper body was out, lower still under. Semen traces lingered on her lips.
"D-Dad... uh..."
She panicked, wiping her mouth—but too late.
"Seo-ah... what the hell were you doing?"
"I... dropped my chopsticks..."
Her voice shook. Lips still glossy, piercing shining with spit.
"Chopsticks? Where—" As he peered under, I hastily fixed my pants. He hadn't seen me yet.
"Ah, here!"
She snatched the fallen chopsticks. Face still flushed.
"Seo-ah... what's that on your mouth...?"
"D-Dad... it's... sauce..."

She wiped frantically. Choi Dong-jin, buzzed and happy, noticed nothing. No way he'd imagine his pretty daughter sucking off a coworker she'd just met.
"Seo-ah, you tell him your ability yet?"
"Not yet... oh right, Oppa, what's yours?"
She grinned at me, swallowing the load I'd left in her mouth.
I didn't know how much she knew, but I summoned a red flame in my palm.
"Fire ability."
"Whoa! So cool!"
"Mine hardens stuff."
Her foot caressed my cock again.
"Cough!"
I spat out my water. Choi Dong-jin burst out laughing. Clueless to her fondling me under the table.
"Hahaha! You punk. Explain properly—sounds weird like that."
"Heeheehee. Does it? It hardens objects."
Choi Seo-ah lifted the tablecloth.
"See?"
It stayed rigid mid-air, defying gravity. She released mana; it flopped down shyly. Plop.
Hmm. No clue what practical use. But... she wasn't my enemy. She'd exposed vulnerabilities, given me attack chances—but no hostility.
So... play along, turn the deceiver against herself as an ally. Best move. Watch till she reveals herself.
"Can you harden liquids?"
"Nah, no."
"Organic stuff like skin?"
"Doesn't work on living things."
I stroked my chin. Could be killer assassination if organics worked, but limited to objects and needs constant mana? Trash tier. Weaponizable, sure... but teach her? When I don't even know if she's foe or friend?
"What do you think, Park? Hardening skill."
"Depends on hardness level for utility."
"R-Right?"
She blinked.
"What changes if stronger?"
"Instantly harden clothes for bulletproofing... that kinda thing."
"Ooh!"
Choi Dong-jin slapped his knee. Her face lit up late.
Actually, hardening light threads into blades—insane potential. Whip tips exploding in faces... endless combat uses. But I skipped attack advice.
True terror: unpredictability. No one expects tissue or cloth to turn steel-hard.
"Yeah... not C-rank. B or even A potential?"
"Yep. C underrates it."
"Inviting you was genius! Park's the best! Kekeke. Cheers! To Seo-ah's A-rank!"
Elated, Choi Dong-jin pounded drinks and passed out first. Choi Seo-ah kept toasting him strong stuff. Still playing innocent, seducing me.
Once he was out cold, she pounced into my arms.
"Wha... what? Your dad's right there."
"Doesn't this forbidden thrill make you harder? Fuck me... secretly from Dad... you want it too."
If it tastes good, devil, god—who cares. Fact: Choi Seo-ah was delicious.
Beside snoring Choi Dong-jin, I pounded her pierced asshole furiously.
"Haaaang~♥ Oppa's cock... feels so good~♥ Oppa best~♥"
Sucking her neck, I confirmed it. Her body wasn't T-12 native. Simple clue: shoulder injection scars. Eighteen faint marks anyone should have. None on her.
No T-12 human lacks injection scars. She wasn't possessing a T-12 body—a demon from another hell entirely.
