A Daughter's Sin is a Mother's Sin
"A bit disappointing..."
On the way out of the school bathroom after fucking Han Chaerin. It was barely worthy of calling it a fuck. She'd cum so hard already today that the moment his dick slid in, she passed out. In the end, just one thrust and it was over.
"Well, can't be helped if she fainted."
He hadn't expected her to black out after a single pump. Seeing her soak herself in pleasure alone left him with a twinge of annoyance. He'd punish her properly later.
"Guess it's time to head home..."
Lunchtime was approaching. No real reason to stick around school. Skipping lectures wouldn't be an issue for a guy like him anyway. So home it was.
Mom's pussy should help me unwind.
There were plenty of women at school to fuck, sure. But if he went wild, they'd all swarm him. That could lead to getting drained to death for real.
"Head home today and plan the next move later."
A shame, but he had his ever-reliable mom at home. He headed to the subway, which was far less crowded than the morning rush. He picked a car with hardly any women. Touching one now might make him late getting back.
"Oh my, Jihoon?"
"...Choi Mijeong?"
Boarding the subway, he ran into Mijeong right away. The mother of Han Chaerin, whom he'd just fucked.

(Choi Mijeong)

"It's been ages since we've seen each other like this~"
"Yeah, it has, ma'am."
She'd stepped out for some errands and was heading home. Never dreamed she'd bump into Jihoon here.
What a lucky day~
Her daughter's childhood friend—and one of the very few men she was close to. He'd played at their house now and then as a kid.
"Has it really been two years?"
"Yeah, since that time at the mart."
He'd come over to play with Chaerin occasionally back then. Mostly one-sided on her part, but still, they'd seen each other pretty often. After middle school, though, he stopped coming by. If not for chance encounters like this, they might never cross paths.
He's a full-grown man now.
As a kid, he'd been cute even as a boy. But as an adult, he exuded something different. Taller and more built than most guys. Just standing next to him made her pussy wet.
"Heading home from school?"
"Yeah, feeling beat today, so early out."
"Really? No need to see a doctor?"
"Nah, nothing that bad."
Men were precious. Any sign of illness, and they should head straight to the hospital. She eyed him with concern, but he brushed it off. Tougher than other guys, he seemed so reliable.
Just being near him has me so turned on.
Her daughter's childhood friend. A kid she'd known forever. But once she started seeing him as a man, she couldn't look at him the same way.
"Chaerin's treating you okay at school?"
"Eh... yeah."
"If she bullies you, tell me. I'll give her a good scolding~"
"Got it. But there won't be any more of that."
Her daughter liked Jihoon too. Just expressed it a bit roughly. From a guy's perspective, it could feel off-putting. She'd warned Chaerin a few times, but her tastes ran that way—hard to change.
The days she hung out with Jihoon, I'd masturbate like crazy when I got home.
Chaerin acted all prim around him(?). Like she wasn't a slutty girl. But at home, she'd spread her pussy and rub one out like any normal woman when horny.
I get off harder fantasizing about Jihoon too~
Porn vids were mostly women in drag. Real guys rarely starred, and when they did, they disappointed. The manliest man she knew was Jihoon. At least on the outside, he turned women on like no one else.
My pussy's soaking already~
Like her daughter, she played innocent around him. Had to pretend her pussy wasn't dripping just from proximity. Otherwise, he might not like it.
"You sure no doctor?"
"I'm fine. Just built up a bit, that's all."
"Oh... huh? W-what did you just say?"
"Just said I'm built up."
"R-right..."
She wondered if she'd misheard. A man "built up"? The words didn't compute. Men had no sex drive. Jihoon shouldn't be an exception. First time hearing something like this.
"So even guys get backed up sometimes."
"Yeah, sex drive kicked in recently."
"That's great news."
She was genuinely thrilled. A man with libido? Every woman's dream.
Jihoon with sex drive... gulp.
His words heated her body fast. A horny man right beside her. Even if he was like a son, instinct as man and woman couldn't be denied.
"S-so, what do you do about it? I wouldn't know..."
"Gotta release the buildup, I guess."
"Right? Can't just leave it?"
Her heart raced. A thrill she'd never felt. Artificial insemination for Chaerin meant no man in her life. For this to happen to her...
"Want to help me out, ma'am?"
"Huh? Really?"
She feigned calm. Couldn't pounce like a bitch in heat—he might hate it. Clenched her fists, holding back the urge to rip off his pants and slurp his dick greedily.
"W-what can I do to help?"
Handjob? Flash her tits or pussy as jerk-off bait? She was ready for anything. Even stripping naked here.
"Nothing much. Play with your tits for now, so suck my dick a bit."
"...H-huh? W-what?"
"Suck my dick."
"For real?"
"Yeah. You hate the idea?"
"N-no!! Why would I? I'm always ready to suck Jihoon's dick~"
Words that shattered her composure. Any other woman would've jumped him. She glanced around. Luckily, only three others. One dozing, head bobbing. The other two glued to phones, ignoring them.
"Then suck it."
"Here?"
"Yeah. Nowhere else to go. Hurry."
Plop.
"O-okay... I'll suck it."
Jihoon boldly pulled out his dick. Rock-hard and exposed. Her mind blanked. Pure female instinct surged, and she engulfed it.

"Glurk, slurp, mmm, glurk, sluuuurp!"
"Feels good, ma'am... mm..."
Unlike Han Chaerin, Mijeong had a softer, calmer vibe. But sucking his dick now, she reminded him of her daughter.
"Glurk, glurk, slurp, glurk!"
The moment he allowed it, she latched on. Her eagerness caught him off guard.
Definitely better than Chaerin.
No husband for Mijeong. Yet her blowjob skills were top-notch. Lonely women honed their techniques over years. Daily dildo practice and sucking built slutty expertise naturally. Even first-time cocks got the pro treatment.
"Guess I'll grope freely too."
Other women still oblivious. He laid her upper body across his lap, slipping a hand into her clothes.
Squeeze.
"Hnnngh!"
He gripped her tit hard. Bigger than Chaerin's, incredibly soft. Pressed against his knee, its heavy weight sank in.
Wrong to think all tits feel the same!!
He hadn't groped tons yet—four women so far—but each had unique softness and texture. Learning hands-on.
"Your tits are super soft, ma'am."
"Thangk yuu, glurk! Slurp! Mmm! Glurk!"
Praised, she bobbed happily, sucking harder. Her mouth-pussy clenched his dick like a real one. Trying not to alert others, she muffled sounds. But slutty slurps escaped inevitably. Lost in his cock, her repressed lewdness poured out in fervent service.
"Perverted enough to love sucking a guy young enough to be your son."
"Glurk, slurp, mmm... haa... any woman would go into heat for a dick like this... smack~"
Even answering, she never released it. Tongue lapping nonstop in devoted worship.
"Your sucking face looks just like Chaerin's."
"What? No way, with my daughter too..."
"Fucked her today."
"I... I see."
Hearing he'd deflowered her daughter, she smiled.
"Must be thrilled for her, getting fucked by a magnificent dick like this."
"She latched on and slurped like a total slut."
"Haa... I see."
Listening to her daughter's lewd antics, she licked even more aroused.
"Was Chaerin's mouth-pussy any good?"
"Decent enough."
"Glad to hear it."
Talking like her daughter's mouth was a pussy. The taboo thrill made her suck harder.
"She used to bully you a bit as kids. Not anymore, right?"
"Yeah. She's changed now."
Squish.
"Hnnngh..."
He pressed her face down on his dick. Humiliating, yet she smiled happily.
"Even Chaerin will learn she's just a bitch once this dick fucks her. Sniiiiff."
She buried her nose in it, inhaling deep. Overwhelmed by the musky male scent, she trembled in bitchy bliss.
Wait... she had Chaerin via artificial insemination and no men since... that means...
A realization flashed. Fucking her daughter amplified the intense taboo.
"Ma'am... you're a virgin, right?"
"...Yeah. I am."
Those words made his dick throb harder than ever.
