50. Pig Mom Develops a New Hole While Son Claims His Junior
Jeong-ah waits alone at home for her son, who will return tomorrow. Squish squish squish squish. "Ngh♥ Haa♥ Hng♥" To soothe her loneliness, she masturbates, then spots the camera filming her and opens her mouth.
"Please degrade this mother pig who's in heat all alone, thinking of her son's dick while masturbating♥ Ngh♥ Ahng♥" It's a video she's recording to get thoroughly degraded as a horny pig later while watching it with her son.
"Laugh at this pathetic mother who can't even masturbate without her son's permission♥ Nngh♥" Pssshhh! She squirts her pussy juice vulgarly and cums, her hips bucking as she savors the afterglow of climax.
"Haa♥... Haa♥... Thank you for watching this mother pig's masturbation♥" After recording, she saves it to the TV for her son to see immediately upon returning home, then wipes up her squirted pussy juice.
"As expected, without my son, my body can no longer feel satisfied♥" In the past, masturbating like this would calm her urges to some extent. It wasn't full satisfaction, but it kept her ruin desire from creeping up, allowing a normal life for a while.
But now, no matter how vulgar and lewd her masturbation, it brought no satisfaction. Filming this for her son excited her greatly, but it still wasn't enough.
"If he were really watching..... Ngh♥" Imagining herself pitifully begging for his dick while masturbating in front of him, she feels her pussy getting wet instantly. Like Pavlov's dog, just thinking of her son makes her pussy drip.
Her body, mind, and life are completely dominated by her son, yet she's living a happier existence. But as a side effect, in moments without him, she feels even more empty and lonely than before.
"A mere female pig shouldn't think it wants her son by her side all day, ngh♥" Since she chose to become subhuman herself, such thoughts are a luxury. She knows this, yet her heart yearns for her son beside her.
"Hoo.... For now, let's hurry and develop it." Though lonely thinking of her son, she has plenty to do alone. Especially developing her body for his pleasure is always thrilling.
Now, she heads to the bathroom with a dildo slightly smaller than her son's dick. She stands it on the floor, picks up the prepared catheter, and squats tensely.
Squelch. "Hnnngh♥" As the familiar dildo slides into her pussy, Jeong-ah trembles slightly at the rising pleasure. Now it's time to develop with the unfamiliar tool.
"Haa♥... Haa♥..." Seeing the thin, long catheter with its small protrusion, her body quivers. This is the tool to develop her piss hole from now on.
"Once I develop it with this, I won't even be able to hold my piss properly..... Ngh♥" Urinating is a natural act for anyone, but from now on, she's turning that basic function into something lewd.
Spreading her legs wide and parting her pussy lips, her tiny piss hole comes into view. Squelch. "Nnggggh?!♥♥" She slowly inserts the catheter into her piss hole.
A cold solid object entering the liquid-emitting hole. Though against human anatomy, Jeong-ah inserts it without hesitation.
"I'll become a female pig that can cum while pissing soon♥ Nngh♥" Since it's unfamiliar development, just inserting into her piss hole makes her body shake with pain.
It would be better if her son did it, but wasting his time on developing this pathetic female pig mother would be unacceptable for a sow like her. Squelch squelch squelch squelch. "Nghk!?♥ Hngk!?♥ Grngh!?♥ Ngrk!?♥"
The alien sensation, incomparable to anal development, nearly makes her stop, but she shakes her hips, gradually getting used to it.
"It's starting to feel good now♥ Ngh♥ Ahh♥" Masturbating with the dildo while developing her piss hole mixes pleasure and pain, accelerating the process.
Finishing in one day is tough, but she must develop as quickly as possible. 'Then my son can play with my piss hole..... Nnggggh♥♥'
Imagining being pitifully catheter-fucked by her son, cumming even from her piss hole like a sow, excites her so much that pussy juice drips profusely. She reaffirms her life as her son's utterly pathetic, plummeting onahole.
"Buhiieeeek♥♥♥" Pssshhh! Shiiiii! Reaching climax, the dildo and catheter slip out as she squirts pussy juice and pisses everywhere.
"Ooh♥... Ooh♥...... Wooh♥" Her mind goes white from the intense orgasm; she trembles idiotically, frozen in the vulgar pose of thrusting her pussy forward.
"Haa♥.... Haa♥.... Haa♥...." Collapsed on the bathroom floor, she realizes her body is already so subhuman that developing it was easier than expected.
...................
"Welcome home, son♥"
"Yeah, I'm heading out soon, so get ready right away too, Mother."
"Yes, understood♥"
The next day, before school, her son comes home and permits her to dress. It's the behavior of a perfectly trained female slave who could go to work naked if he ordered.
"Oh! You said you started developing your piss hole yesterday—show me."
"Yes, here it is♥"
In her suit, she lifts her skirt to reveal her bare pussy. Without permission for underwear, she lives panty-less as a matter of course, with only heart-shaped nipple patches instead of a bra on top.
"Ooh~ So you're developing with this."
Squelch squelch squelch squelch. "Ngh!?♥ Ooh♥♥ Ngh♥ Ngh♥"
Taesu grabs the catheter like a fun toy, poking her piss hole curiously. 'It's several times better than doing it myself♥♥' The pleasure is far more intense than self-development; she nearly cums on the spot.
If her son develops it, the time might shorten from a week to three days. "Good. From now on, even removing the catheter to piss requires proper permission."
"Haa♥.... Ngh♥ Yes, understood♥"
Her life is restricted even in pitifully pissing, but Jeong-ah's face beams with genuine joy. "And Boyeon seems like she'll train faster than expected, so keep that in mind."
"Yes♥ From now on, we'll get along well as your son's female slaves♥"
Her son thinks it's too early for senior Eunji, but believes junior Boyeon, whom he started training yesterday, is ready to meet anytime. Curious how he knows them so well, she doesn't ask.
Because the end result will be the same anyway......

"Submit the report on the new product under development and bring the quarterly sales graph."
"Y-yes, understood, President."
At the company, gone is the homebound sight; Jeong-ah works with charismatic president aura. At home, she's just a sow, but after years of suppressing her urges to work diligently, she's a recognized talent in the industry.
After assigning tasks to her secretary, she enters her office before lunch to rest, slumping in her chair. "I really picked a great secretary."
Her slightly timid personality is a flaw, but her processing ability is top-notch—that's why Jeong-ah chose her.

(Byeon Taehee)
Of course, she struggles with collaborations due to tension, but assign tasks that play to individual strengths, and it's fine. In that sense, current secretary Byeon Taehee is competent.
"Now then..... Ngh♥" Alone, she immediately spreads her legs, grabs the catheter in her piss hole, and starts masturbating by poking it.
"It's really starting to feel good now♥ Ahng♥ Ngh♥" Her piss hole, developed since yesterday, can already feel urethral pleasure.
Though poking her piss hole makes pussy juice drip and dirty the floor, she ignores it. "Ahh♥ Ngh♥....... Haa♥..."
Right before climax, she stops her hand to deny orgasm. Because it felt like she'd piss if she came now, she hurriedly calls her son.
"Son♥ I'm calling to ask permission to piss because I need to go."
"Yeah?"
"Lunch break's soon.... The other employees go out to eat, right?"
"Pardon? Y-yes.... Usually they go out for meals, so the office is empty during lunch."
"Perfect. The company must make you delusionally think you're human without me there, huh?"
"No♥ No matter when or where, I'm your lowly female pig♥ I was just a pig delighted by urethral masturbation until moments ago♥" Denying her own humanity, she reaffirms being her son's sow.
Just saying it makes her heart race wildly with excitement. Whether he sees or not, feeling pathetic as a mere sow soaks her pussy even more.
"Then....."
At her son's following command, she trembles, a lewd smile spreading across her face.
