The Daughter's Sin Becomes the Mother's Sin (11)
This time, it really felt like she was drowning. I scooped Yujeong out of the bathtub in a princess carry, just like I'd done to Yujin before.
I was about to head straight out, but then it hit me—I'd been so distracted playing with Yujeong's tits and fingering her pussy that even though we'd been in the bathroom for ages, I hadn't properly showered yet.
So I sat the limp, whimpering Yujeong—who'd lost all her strength after two orgasms—on the toilet seat and slathered a massive glob of body lotion over her tits. I'd kneaded them endlessly already, but they still felt incredible to touch.
Then I grabbed those burdensome handfuls from both sides with one hand, rubbing the lotion into her cleavage like I was titfucking her. Soap bubbles bubbled up thickly over her breast valley.
"Hold 'em tight."
I grabbed her dangling arms and lifted them up as I said it.
I figured she'd refuse out of sheer defiance—half-joking on my part—but surprisingly, Yujeong obediently pressed her tits inward just like I told her to.
Her compliance was so eerie that I glanced at her face, and her eyes were completely unfocused.
Hmm, surprising, but whatever. Her tightly squeezed-together cleavage was plenty wide enough to hold the bubbles, and I didn't want to waste more time washing up. So I decided to make good use of this portable soap bubble stand called Yujeong.
I scooped the bubbles from her tits with my palm and smeared them over my body, then started applying them to hers too.
It felt almost too nice of me, but it wasn't hard or anything, and every inch of her skin—from her tits and ass down to less sensitive spots—was soft and smooth enough to get my cock rock-hard. She deserved this much service.
My palms glided over her tits and ass, of course, but also her belly, nape, inner thighs, calves, behind her ears, and even the soles of her feet.
"Hngh... hngggghhh."
Every time my palm brushed a sensitive spot, Yujeong shuddered and let out these pitiful moans.
Once I'd soaped up her body, I rinsed her off before doing my own—pouring water over her first.
Whoosh—
The suds washed away from her nape, back, and waist. But with her sitting there like a dummy, the rest wasn't easy to reach.
I lifted the arms of this toilet-perched idiot and rinsed her armpits too. Then, to wash her belly—where the massive tits were acting like a shop awning, blocking all the water and leaving suds intact—I told her,
"Get up, aun—sis."
Maybe it was the pathetic display she'd just put on for me, but even though I'd sworn to call her "sis," the word "auntie" slipped out again.
I braced for her to snap back like the auntie she was, all venomous and sharp, but Yujeong just nodded with a soft "Mm," showing me a submissiveness I'd never seen before.
I'd been ready to finger-fuck her pussy again if she got cheeky, but she obeyed so nicely that I missed my chance.
Whatever, didn't matter. If I wanted to touch, I'd touch.
I splashed water on her standing belly, pretending to rinse the suds, then naturally slid my hand lower when they didn't seem to wash off easily. I rubbed her lower abdomen.
"Eek—!"
Like a goddamn virgin. For an auntie.
She'd been body heat was a bit higher than most, but her lower belly felt especially hot.
Probably because her uterus factory was in overdrive—orders weren't coming in as closing time approached, making it busier than ever.
She clearly noticed my groping had gone way beyond rinsing, but unlike before, Yujeong didn't grab my hand or lecture me arrogantly.
She just let out low, breathy "Hnggh... hnggggh..." moans now and then.
I pulled my hand away after groping plenty. No touching her pussy yet.
A quick finger-fuck made her squirt and cum like a pathetic premature pussy? Nah, I wanted to build her pleasure slow and steady over time, then shatter her with a real orgasm.
Drag elite socialite Yujeong's smart brain down to the level of a horny female chimp in heat, obsessed only with sex, pussy, and cock.
Seeing me pull away, Yujeong let out a disappointed "Huh?"
I shot her a glare for a split second, then smoothed my expression.
Just two orgasms, and this was the change? The bitch who'd been so strict and unyielding to pre-regression me was this weak a pussy deep down?
Revenge was giving way to sheer bafflement now. But I comforted myself knowing I could dump all this confusion on her soon enough. I splashed water on myself roughly, then toweled off.
Once the droplets were mostly gone, I looked at Yujeong. There was an extra towel, but she wasn't wiping herself—instead, her pleasure-glazed eyes just stared at me blankly.
What? Oh... she wanted me to dry her?
Fine. You pathetic pussy bitch. I'll do it. Since I'm gonna use your pussy however I want soon anyway.
I stepped behind her, prodding her ass with my cock as I unfolded the towel and wiped the moisture from her body.
She leaned back against me naturally, eyes closed, humming a little tune, savoring my touch.
Her body was dry now. I tossed the towel aside and opened the bathroom door. Cold AC air rushed in, snapping Yujeong back to reality—she blushed in shame, grabbed the dropped towel to cover herself, and scurried out like she was fleeing.
I grabbed her wrist. Stepped out first, then turned to face her. The post-two-orgasm glaze in her eyes had sharpened again.
"What? Let go of my hand?"
She snapped at me sharply.
But her voice had lost its old edge long ago. It was just a forced attempt to act like the chairwoman in front of me.
Proof? Her words were tough, but she didn't even try to shake off my grip on her wrist. Instead, her fingers crept toward my forearm, stroking it softly—as if she didn't even realize she was doing it.
"Put these on."
I pointed to the new stockings and panties she'd begged me to hand her.
She clutched the towel over her barely covered tits, glaring like what's your game now?
As if she'd already shown me everything, and I'd groped every inch of her— what was the point of putting on stockings and panties in front of me now?
"I wanna watch."
Not a lie—pure truth. And for her, half-dressed in slutty lingerie would feel more humiliating than full nudity.
"Even if I say no, you'll just force me anyway, right?"

I hadn't planned to force her, but she nodded like she'd rationalized it that way and obediently slipped on the black stockings and white panties. Cheekily, though, she added something I hadn't approved—a little bra shim.
Her tits weren't the type to be contained by that anyway, and I planned to rip it off soon, so I let it slide.
"There. All dressed."
Her voice mixed 30% shame, 60% anger, and 10% weird excitement.
Mm, nice. Hot as hell.
"Ready to get serious now?"
I grinned brightly, voice full of glee.
Arms crossed under her tits, Yujeong froze for a second, then bowed her head diagonally and muttered,
"So... what we just did... wasn't even the start?"
Of course not, you pathetic pussy bitch. Cumming from a little fingering like that.
I nodded, grabbed her arm, and pulled her along. Stepping naked from the steamy bathroom into the cool AC felt refreshing.
I chugged an energy drink for hydration and the stamina I'd need soon. And since she'd cum buckets in there, Yujeong needed fluids more—I offered her a can.
"Here."
"You bought it with my money...! Don't act generous!"
Her actions said otherwise—voice prickly, but she took it without refusing. Thirsty as hell, apparently.
While she drank, I sat on the bed with the brush pen and phone, grinning ear to ear. Like I couldn't get enough of this moment with her.
She tossed the empty can toward the trash and I said,
"Come here, sis."
She clicked her tongue but approached without retort.
Yujeong stood before me. I uncapped the brush pen and spoke again.
"You remember our deal, right?"
"Of course I do. That's why I'm here doing this!"
Her momentum had tanked after those two pathetic orgasms, but mention her daughter and she changed. Eyes and voice full of murderous intent—like she'd never forgive a single finger laid on Yujin again.
I nodded, thrusting the pen tip forward. We'd wasted time with her bathroom freakout, but nothing had changed.
Well, actually—I'd learned how pathetically weak her pussy was. Big harvest.
"Turn around."
"What? You bas—"
"On your face then?"
"You son of a... bitch."
Arms crossed, she glared like she wanted to kill me. Nothing like the cheap slut giggling on the brink of drowning in the tub moments ago. But she had no choice.
She muttered "Yujin-ah..." softly, swallowing her humiliation, and turned.
I smacked her cheekily wiggling ass with my palm.
"Bend over. Thrust that fat ass toward me. Can't even use it right."
"Kkh!"
Trembling with shame, she bent at the waist anyway, shoving her huge ass toward my face as I lounged comfortably on the bed.
I turned her plump ass into a blackboard and started writing our contract terms.
"Wait! What if it washes off? Write on paper. Easier to store and split."
"Then rewrite it yourself next time. Anyway, every time you come see me, this contract—"
I smacked the spot right above the first letter I'd written.
"Khak!"
And continued.
"—must be here. Or our deal's off. You said you remember the terms, right? Recite them. Match what I write."
This was all part of my twisted play to humiliate her, but serious businesswoman Yujeong thought I was just confirming the deal. She recited in a stiff, textbook voice.
The brush pen scratched letters onto her left ass cheek. She cleared her throat with a dignified "Ahem"—that same cold, strict tone from lunch breaks.
[Follow the school rules!] [No running!] [Focus on studies!] [Romance strictly forbidden!]
Now reading our sleazy contract aloud in that voice.
"Party A, Lee Yujeong, and Party B, Kim Sa-hyeok, hereby enter into the following contract. Hereinafter, Lee Yujeong shall be referred to as Party B, and Kim Sa-hyeok as Party A."
The pen moved.
"Contract duration limited to a maximum until Party A graduates."
Black ink soiled her white ass.
"Work location: anywhere. However, significantly restricted at Party B's workplace, the school. Also restricted late at night, but absent special circumstances for Party B, Party A's 'desires' take priority."
The pen flew through the duties. But Yujeong hesitated.
"Duties consist of..."
"Duties?"
"Anything... as long as it's what Party A wants..."
I didn't let her gloss over it. Smacked her ass hard again.
Smack!
Her legs quivered. She started to stand, so I pointed at her face like stabbing with my finger.
"Freeze. Don't move. Say it right. Anything? So if I say I wanna beat the shit out of you to satisfy my urges, or chop off your limbs—what then? 'Anything' makes that part of the deal too."
She sighed, agreeing it was fair.
"Duties: Party B jerks Party A's cock with her hands. Party B sucks Party A's cock with her mouth. Party B squeezes Party A's cock with her tits. Party B takes Party A's cock in her pussy. And..."
"And?"
"Party B..."
"Yujeong...?"
Her legs shook again. Not even a prick would draw blood from this woman, but this broke her—she teared up, drops falling from her face. I considered soothing her but held back. Deals must be cold.
"Party B! Being an auntie of lesser value compared to Kim Yujin, the subject of this deal with Party A! Shall offer her virgin asshole to Party A once only!"
Finally done, Yujeong collapsed into sobs—"Uhheuk!"—and crumpled to her knees.
