Aren't You Feeling the Urge to Pee?
Mom entered my room.
"....Master...? Did you... enjoy yesterday's lesson...?"
"..Yeah.."
Oh ho. So it's lesson time from the morning this time?
After seeing my sister's face earlier, it seemed she wasn't here to scold me but was simply envious.
"Hehe... Master, by any chance... aren't you feeling the urge to pee?"
As it happened, I did need to go.
"The lesson I can give you right now is about peeing."
I could pee perfectly fine on my own, though.
"It's not only semen that you can release onto a woman, you know?"
"Like how you peed in A-Young's throat yesterday...?"
"Hehe... Yes! That's it..!"
Hmm... So that's what this was about.
"Yesterday you peed on me to save me, but today I'll help you pee directly!"
"But I've already peed plenty on A-Yeon, haven't I?"
Since there was a limit to how much I could pee, I had been planning to give it to A-Yeon this time as an apology...
Sorry... A-Yeon!
"Then I'll help you collect it in this pet bottle!"
"If you store it like this for the future, other women will definitely love it too!"
The pheromone didn't have a common-sense alteration effect...
It seemed her mind had gone haywire from the aphrodisiac, addiction symptoms, and excessive pheromones in the urine.
This appeared to be the result of pheromone overload combined with Mom's unique tastes.
"Definitely... any woman would love Master's urine! You absolutely must save it..!"
"Whenever you feel the need to pee, I'll help, so... just call me..!"
"Uh.... yeah..."
I really couldn't get used to this at all.
How had Mom ended up in this state?
Why was she suddenly so eager to receive my urine out of nowhere?
She pulled out my cock, held it gently, and began slowly massaging it while smelling it and blowing warm breath across the tip.
She pressed the pet bottle against my glans, opened her mouth wide, and created the sensation of resting my cock on top of her lips.
Even her breasts, pressed against my thighs, kept leaking streams of breast milk.
"Shiiiiiiii! Shiiiiiiii! Pee like that!"
"............"
"Shiiiiiiii!"
The strange stimulation and sense of immorality created such intense sensations that the urine refused to flow easily.
Instead, it felt like something else was about to come out...
"Shiiiiiiii!"
She kept imitating the sound of peeing. As if her tongue had a mind of its own, she licked relentlessly at my glans while her hand continued stroking up and down the shaft.
Was this really supposed to be about making me pee?
Instead, something else was trying to come out.
I grabbed Mom's head and pressed her face against my balls.
Mom happily took them into her mouth, rolling them around with her tongue.
At the same time, her nose kept rubbing against the base of my cock, stimulating it further.
She even buried her nose against the root like a madwoman and sniffed deeply. The hot breath bursting from her nostrils created an entirely different kind of stimulation.
Mom's hand stroking my shaft never stopped moving and gradually picked up speed.
Finally, semen began rising up my cock.
When Mom saw the white semen emerging from the tip, she hurriedly tried to catch it in her mouth, but her stomach was already full, so it overflowed. After spraying a little across her face and hair, the rest began pouring into the pet bottle.
She licked my cock and murmured.
"Hehe... If it's mixed with semen, they'll definitely like it even more.."
Since it was a 1.5-liter bottle, there was still plenty of room.
After I finished ejaculating, the urge to urinate finally began to build.
Even then, Mom kept stroking as if trying to transform that urge into another climax.
"Shiiiiiiii..."
Her breath washed over my cock as she spoke directly against it.
With her face almost completely hidden beneath my shaft...
Was she really telling me to pee? Her actions didn't match her words at all.
I endured the distraction and focused entirely on urinating.
Shiiiiiiiiii...
The pet bottle shook from the force of the stream as she held my cock steady.
Dribble... drip...
When the flow began to end, she gripped the base of my cock, gathered the remaining urine, and squeezed every last drop into the bottle.
The 1.5-liter pet bottle filled up in an instant. It was becoming difficult to consider this a normal human body anymore.
Chuu! Chuu! Chu!
For the final drops that refused to come out no matter how hard she squeezed, she sucked them clean with her mouth.
"Hehe... If you need to pee in the future, just tell me..!"
With that, Mom took the pet bottle and left.
Where on earth was she going?
I didn't follow her immediately. After waiting a moment, I trailed after her from behind.
Mom's back looked furious. Her firm ass trembled as semen leaked from her anus and pussy.
Because her voluptuous body moved so quickly, her breasts and ass jiggled with every step.
Even though she's my mom, she really has a lewd body..
Mom headed straight for my sister's room and, without hesitation, upended the pet bottle—containing my urine mixed with semen—directly onto my sister's face.
Then she unleashed a torrent of words like a machine gun.
"What is that face supposed to be? No matter how dirty you roll around, at least wash yourself...
Your little brother felt so disgusted by the smell of a rag that he couldn't even eat his food!"
She must have carried the same smell herself, yet she pinned all the blame on my sister.
My sister seemed completely dazed by the sudden urine shower pouring over her head.
And then came the incredibly insulting words from Mom.
Mom had never been this kind of person before.
"....You vixen..! How could you do such things under the table while your family is trying to eat?"
It was hard to tell because of the urine, but I could see that my sister was definitely crying.
"You don't even know the grace of being raised and you're so ungrateful...!
You dirty, rolling whore—how could you do that to your own little brother!?"
Mom, unaware that my sister had actually been a virgin, seemed to have formed a fixed prejudice based on how she usually dressed and behaved.
Of course, I was the one who had taken that virginity.
Although Dad had favored her, the one who truly shared warm, emotional bonds with her was Mom.
That was why being misunderstood and insulted by Mom must have been absolutely devastating.
"If you like semen that much, then don't eat rice anymore!
Live your whole life eating nothing but semen, you rag-like bitch..!"
"N-No, that's not..."
The moment my sister tried to speak,
Slap!
Mom struck her cheek. Semen and urine from Mom's hand splattered everywhere, including the fluids already in my sister's mouth.
The sudden violence from a mother who had always seemed endlessly kind felt like a rock to the skull.
I barely held back the laughter threatening to burst out at the sight of semen continuously spurting from Mom's trembling, furious body.
"Hiccup!... Sob sob... That's not true..!"
Slap!
"Don't make excuses! Do you think I don't know what kind of girl you are?!"
"Without a doubt, a rag like you must have seduced our innocent Myungho!"
Suddenly Mom lifted her foot and began stomping on my sister's pussy.
"Uaaaaaack! Ahk! It hurts! It hurts! Mom...! Hic!"
From Mom's no-panties pussy and ass as she raised her leg, the semen and urine I had pumped into her kept flowing out.
Even so, our poor sister failed to notice how strange Mom looked, lost in her own misery.
"I'm going to crush this filthy pussy! I'm going to destroy it!
But don't you dare leave... Dad can't find out, so don't leave..! Understand?
If you leave, I'll tell all your friends what you've done—that you're such a dirty slut!
And if you try to seduce our innocent Myungho in this house again! I'll kill you!"
Pouring out all her rage, she ground her foot against my sister's pussy so hard it seemed like it would tear apart.
"Aaack! Hooong... It's really not true! I'm telling you it's not.... Uhuhuk!"
But my sister—crying with such a pitiful, adorable expression—only fueled Mom's anger as semen and urine continued dripping from her mouth.

"So you seduced him by acting all pitiful and cute like that..?!"
"Hic...! I really didn't seduce him..! It's unfair, I swear..!"
"Stop lyyyyying! You were the one wagging your tail at our Myungho!"
As Mom screamed, semen and urine from her mouth kept splashing onto my sister.
Before long, my fluids from the pet bottle had completely soaked into my sister's bed.
"You smelly bitch... You're going to sleep right there on that for the rest of your life... Can you handle that..?"
"You're that kind of rag-like whore who loves this stuff, aren't you?!"
"Huk... huk.... Hwaaaaaang!"
My sister wailed in despair. Knowing the truth, I couldn't help but feel pity for her.
"So... you were crying like that... while wagging your tail at Myungho..? Pretending the world was so hard on you.."
When my sister kept insisting it was unfair and continued crying, perhaps Mom's usual kind personality began to return?
Her tone gradually softened, and I could sense her hesitation.
Now that both of them were my women... I wished they would stop fighting and get along.
"Hwaaaaaang! It's not true..! I'm saying it's unfair..! Hooong!"
"...Uht... S-Stop crying... Uh... You're spilling semen everywhere from your mouth.. Sorry... Mom is sorry.."
It was a strange sort of comfort, but she was trying to console her nonetheless.
Now overwhelmed with guilt, Mom pulled my sister into her arms.
"I'm sorry.. Mom is sorry... I won't do it again.. I'm sorry.. Don't cry, my daughter.."
"Hwaaaang! M... Mom, I hate youuu!"
With her emotions exploding, my sister sobbed and clung tightly to Mom.
After they held each other for a while, they both seemed to calm down.
"Huk! Huk!... Huk... Mom... You smell, Mom.. My mouth is filthy with semen and pee... You can't touch me.."
Worried that the dirty fluids covering her would get on Mom, my sister tried to push her away.
"No... It's not dirty.. Myungho is my precious mas... son, you know..?"
"Not dirty...? Uh.... uh..?"
Sensing something strange in Mom's words, my sister finally began to notice both the urine poured over her and Mom's bizarre behavior.
"Wait a minute... Mom, what's that on your body..? That's not from me..."
My sister pointed at the semen and urine flowing from Mom's mouth and thighs.
"Ah.... Aha... Ahaha... That... This is... Well..."
Mom, who had insulted and scolded her own daughter without realizing she was in the exact same position!
The mother who had always been demure and angelic was actually receiving her son's semen just like her daughter..?
And despite that, she had said such horrible things and poured urine on her?
"Mom... Have you been doing those things with your son..?"
"Ah.. No.. What do you mean by that...? This is, well, it's not like that.."
Seeing Mom's strange words and physical state, my sister made a guess and one suspicion arose.
"Mom... Did you do those things to your son..?"
"Uh...uh..? No.. That can't be..?"
Mom tried to deny my sister's guess, but—
"It's true, isn't it? It is! How could Mom wag her tail at her own son?"
Not only could she not think of any counterarguments, but the semen and urine continuously flowing from her body turned suspicion into certainty.
Moreover, every time she tried to refute it, the semen and urine visible in her mouth only made things worse.
"Hmph...! You were jealous of your son and took it out on me..? How could you do that to your own daughter?"
My sister glared at Mom with her cheeks puffed full of semen.
"Then what about you! You said it wasn't true, but aren't you exactly the same? Are you in any position to lecture me?!"
Mom glared back with her own cheeks puffed full of semen.
"Have you already forgotten that you did it to me first?"
"Uh.... B-But that was...!"
"Get out! Get out of my room! What does it matter what I do with my little brother! Get out right now!"
"W-What!? Then you stay out of what I do with my son too! You're no different!"
With her face completely flushed red, Mom stormed out of the room.
I dodged the rushing Mom and hurriedly fled into the next room.
