Family Harmony is the Best
"Whoa, this is so gross. Aren't you embarrassed at your age? I swear I won't grow up to be an adult like you, Oppa. Look at that—a twenty-year-old guy giggling while rubbing his face on Mom's huge tits. It's so creepy, my skin's crawling all over. Ugh!"
The moment she crossed the front door, her vicious little sister unleashed a barrage of insults right off the bat. The blatant disgust showing under her furrowed brows was no different from yesterday. Had all his efforts to mend their relationship gone down the drain after just one day?
Of course not. Mixed in with the disgust in her gaze was clear jealousy toward another female.
Mom had a word for such a little sister.
"Hyeonju, what kind of way is that to talk to your brother? How many times have I told you to fix that rude mouth of yours?"
"Well, what am I supposed to do? It seriously makes me wanna puke. Mom, you stop it too. Your son isn't a kid anymore. He's two years older than me. He should be in college or working a job, taking responsibility for his own life, but you keep indulging his whining, so he never grows up!"
It was such straight talk that no one could argue. Any little sister would blow a fuse seeing her naked brother nuzzling Mom's massive rack like that.
But to Yu-ran, her daughter's perfectly valid complaint just looked like the schemes of a spiteful bitch trying to drive a wedge between her and her son.
Still, since the point itself was irrefutable, Yu-ran didn't counter the logic—instead, she switched holes to find an escape.
"More importantly, Hyeonju! What kind of girl comes home from school without basic manners? Don't you have to greet your brother properly first?"
"Ugh...!"
Another unassailable truth. When right meets right, the one with more power wins. Yu-ran sharpened her glare at her daughter's cheeky eyes and pressed on.
"You don't skip proper greetings when I'm not watching, do you? If you do, I can't just let that slide..."
"F-Fine, I do it! Do I look like some girl who can't even follow basic etiquette?"
Of course she didn't. Hyeonju wasn't flexible enough to bother with embarrassing manners when Mom wasn't around to see.
The problem was, if Oppa opened his mouth carelessly here, her position would tank—but he was sharp enough to stay silent.
"Is that so? Then show me right here in front of Mom."
"Mmm... F-Fine, I got it..."
Hyeonju's cheeks flushed bright red as she set her bag down, neatly folded her school uniform, and placed it in front. Then, facing Oppa, she bowed deeply on the floor and reported her day.
"Your exclusive little sister toilet has just returned home. Thanks to the cock kisses you permitted today, Oppa, I had a fulfilling day. At school, we learned outdoor leash training, obscene language usage, pussy sex practice, and handjob shows. Of course, to uphold my duties as your dedicated toilet even at school, I came twelve times total from clit-pussy masturbation—and my fap material was, naturally, your magnificent cock, Oppa. Now that classes are done, please use my pussy as much as you want while I'm home, and I'll serve you to the best of my ability."
Finishing her words, she knocked her forehead twice against the floor—thunk, thunk. For a greeting she usually skimped on when Mom was around, it was impressively sharp and polished. Even Yu-ran couldn't nitpick it.
The recipient himself seemed pleased too.
"Mm, very good. Our little sister did even better than yesterday's greeting, huh?"
"Y-Yeah? Well... of course I'd improve from yesterday."
In truth, she hadn't done any such greeting yesterday—they'd come home together. But by phrasing it that way in front of Mom, Oppa was deliberately dispelling her suspicions. Hyeonju caught on, of course, and felt grateful for it.
Sensing a subtle vibe forming between the two, Yu-ran jumped in a bit hastily.
"But with all that time at school, you only fapped twelve times? Isn't that a lack of awareness as a dedicated toilet?"
"Ah, why nitpick again? You think I just fap all day at school? I hang out with friends during breaks, go to the bathroom, review before class—should I skip all that and just fap nonstop?"
"Hey, watch your mouth! When did I say not to do anything during breaks? Depending on your technique, you can cum over seven times in a ten-minute break. I'm telling you to hone your skills with more dedication as your brother's toilet, but you take it all wrong? Back in my day..."
The mother-daughter duo was at it again, sparks flying in seconds. They hadn't been super close before, but lately, these squabbles were constant—and Oppa (or her son) was always at the center.
"To begin with, Mom, aren't you clinging to Oppa way too much? How old are you to act like this? Don't you think it's time to retire now that there's a young pussy like me around? You look way past your expiration date as a fuckhole anyway."
"Look at this inexperienced brat talking big. Don't say that until you've got a constant clit boner thinking of your brother 24/7. This mom thinks of Oppa so intensely that I fap to his cock even at work. Hell, I'm custom-ordering a work chair with a dick mold of his attached. Think you can match that passion?"
Poisonous barbs and mockery flew back and forth. A catfight teetering on the final line. Normally, Hyeonju would yield and keep the balance, but today it shattered for some reason. Such one-sided truces never last long anyway.
From the son's perspective, this catfight wasn't so bad. Two women fighting over him? Pretty romantic for a guy. But like all fantasies, when they become reality, they come with a sausage-full of headaches.
As the sharp, shrill voices bounced between them, his skull started throbbing. They showed no signs of calming down on their own.
No choice, then. Time for the mediator to step in.
The son grabbed Mom's nearby clit and twisted.
"Nyaaahhhn?! S-Stop! Stop! S-Son! Sorry! Mom was wrong! Too loud, right!? Sorry, sorry!"
The instant he pinched her clit, Yu-ran reflexively spat out apologies. No matter what he did to express displeasure, it was always her fault—that bone-deep mindset produced such a reaction.
For him, it was just a casual way to stop the fight and grab attention.
"Mom, ease up on Hyeonju. She's trying hard—what's the big deal? Unlike you, she was a virgin pussy until recently, so some shortcomings are inevitable. She seems to be working hard at school too, so don't push her that hard. And you saw it, right? She called me 'Oppa' properly this time instead of 'you.' That's huge progress—put too much pressure now, and she'll rebel."
"...Sorry..."
Mom bowed her head in deep remorse. Not for how she'd treated Hyeonju, but purely for upsetting her beloved son.
Meanwhile, Oppa had a word for his wayward little sister too.
"You too, you know. What's with that tone to Mom? She's ahead of you as a pussy bitch, so show some respect. You've got a long way to go. Got it?"
"...Yeah, whatever..."
Hyeonju turned her head away in a pout. But her eyes stayed fixed on Oppa, and fidgeting with her fingers, she sneaked peeks at his reaction—clearly regretting her outburst.
At her cute response, Oppa chuckled and pointed at his cock with a finger.
"Come here. Mom, get off the sofa and kneel too. Time to make up properly."
Yu-ran hopped off the sofa at his words and knelt demurely before her son. Hyeonju crawled over on all fours, feigning reluctance, and settled beside Mom.
With their faces positioned, a thick cock slid between them.
"Now, swear to make peace."
Mom took the cue and voiced her oath.
"I swear never to provoke or fight with my daughter again when I can't even act my age. Mwah♥"
Followed by a devoted kiss on his cock.
Then Hyeonju, in her twisted, bratty tone—but clear all the same.
"I swear never to call Mom an expired pussy bitch again. Mwah♥"
Their oaths sealed with kisses on his cock. At least for now, they'd keep each other in check and strive for family harmony.
Family really is best when it's harmonious.
"Good girls. Well done. Heh heh, now that the peace oath is done, let's strengthen our family bonds tonight? Feeling like some mother-daughter rice bowl."
Pussy juices leaking from the mother-daughter duo soaked the floorboards.
