Since things had reached this point, Heo Seong-ah decided she might as well see it through to the end and let out everything she’d been holding inside.
“You said it would be okay until today, didn’t you? M-Master, you said you’d punish me starting tomorrow, and I even apologized and promised to work hard… So why…”
“Hah, you fucking bitch.”
“Hic…!”
It was a trivial issue something that could have just passed by with a laugh, as if nothing happened.
But Heo Seong-ah’s crossing of the line was something Jun-ha simply could not accept.
“Who said it was okay until today? Did I say that, Seong-ah? And when did I say I’d punish you starting tomorrow? I said ‘from now on’ you’d be punished if you didn’t excrete. Doesn’t ‘from now on’ include now?”
“T-That is… I mean…”
“And you, you stupid bitch, when your master says you’ll be punished, you’re not supposed to question it. What, you need a reason you can accept? If you can’t accept it, are you going to resist me by force?”
“N-no!! I’d never dare…”
“But you think it’s okay to talk back and be stubborn whenever you like?”
Swept up in the flow, Heo Seong-ah found herself unable to refute anything.
“A reason? Okay, you fucking bitch. I’ll punish you because I hate the sound of your breathing. How’s that? Or your tits look so damn sexy I want to punish you. Is that enough reason? Hm?”
“I…hic, I’m sorry… Master…”
“Try to see the good in you and you go and ask for punishment.”
With a deep sigh, Jun-ha brought over a bunch of adult toys still in their packaging from the shelf.
A tube of lube, a black silicone urethral plug, an anal plug, and a 300ml disposable plastic syringe.
“Eek…”
Guessing at the punishment she was about to receive, Heo Seong-ah trembled all over.
“Listen, you fucking bitch. The punishment I told you about was what I said yesterday.”
“Y…yes..?”
“These two. I said we’d do them yesterday, didn’t I?”
Jun-ha waved the urethral and anal plugs in his hand.
“M-Master… I, I’m sor ”
“No. Don’t apologize. You just piss me off.”
“Hic…”
There was never any punishment added today.
It was all a misunderstanding Heo Seong-ah caused by jumping to conclusions.
“And this is a punishment you earned by acting like such a bitch just now.”
This time he grabbed the 300ml syringe.
“I was planning to plug your urethra and ass until the excretion training was over. But since you’re being such a pain, you need a harsher punishment, right?”
“N-no! I’m sorry..!”
“Shut up and listen. From today, every night I’ll fill your bladder with 300ml, and your back hole with 1 liter of water, plug you up, and leave you like that. Since you brought it on yourself, just accept it.”
“Hic… Master…”
If she’d just kept her mouth shut, none of this would have happened.
The tragic result was purely her own misunderstanding, so she couldn’t say another word.
“Master… Hic…”
“Now get down. Before I get even more pissed.”
“Hic…”
Jun-ha’s voice was loaded with explosive anger.
Terrified, Heo Seong-ah moved her shaking limbs and pressed her chest and face to the cold, bare floor.
Since it was night, the chill felt even sharper against her skin, and to make things worse, she felt the urge to pee.
“Kk…”
But now, in this mood, she couldn’t say she needed to pee.
Biting her lip, Heo Seong-ah quietly reached down and spread her pussy.
“That’s right. See how much better it is when you just behave, Seong-ah? Keep doing that.”
“Yes, Master…”
Her attitude had become compliant.
She’d learned the hard way that accepting whatever was done to her without protest was the right choice…
If minor punishments kept stacking up, eventually she might truly become an amputee onahole with no way back.
“Ugh…”
Wanting to survive, Heo Seong-ah resolved to make herself into an emotionless toy.
“Spread your pussy properly.”
“Yes, Master.”
She used her fingertips to open herself as wide as possible.
Below her always-wet pussy hole, clear juices beaded up and turned into droplets, stretching into strings as they finally fell to the floor.
“No matter when, it’s so fucking hot to look at.”
“Hic…”
A perfect beauty with a body and face to match, spread wide on the floor as if begging to be fucked
It was a vulgar sight only a select few could witness.
Just her glossy, wet slit was stimulating enough, but the sight of thick, sticky juices dripping down made a scene as beautiful as a painting.
He could have snapped a photo and auctioned it for a lot of money, but being rich, Jun-ha just enjoyed the thought.
He wanted to keep the image of Heo Seong-ah the university goddess looking this degraded all to himself.
“Stay still, okay?”
“Yes, Master…”
Leaving her alone, Jun-ha fetched a large canister from the basement corner.
He struggled to carry it with his skinny arms he was hardly manly at all.
“Know what this is? It’s called glycerin… or whatever, basically just a liquid you shove into your urethra and ass.”
“Yes…”
Using milk or glycerin for enemas is said to be cleaner and safer than water.
He’d bought three tanks of glycerin instead of risking spoiled milk
though now he realized he had a “milk-cow” in the basement anyway.
“Starting tomorrow, you’ll be doing enemas with the milk you pump. That means you’ll have to produce at least 3 liters, got it?”
“Ye…eh..?”
To have to feed her own breast milk to both her upper and lower holes…
Could things get more miserable than this?
“Master… hic…”
“Tch, shut it. If you can’t, you get punished.”
“Yes..!”
He didn’t need to threaten any further.
Just the word “punishment” was enough to make Heo Seong-ah obedient.
“Now stay still.”
“Yes, Master…”
Jun-ha unpacked the tools and lined them up.
First, he grabbed the 300ml syringe and plunged its tip deep into the glycerin drum, pulling back the plunger with some effort.
“Let’s see…”
He’d bravely said he’d stick it in her urethra, but the tip was really too thick to fit.
Looking for a solution, Jun-ha spotted the rubber nozzle included with the syringe.
It was a long, 1-meter soft tube that could connect to the syringe.
“Ha.”
It seemed the manufacturer had included the extra part just for this use.
Thinking it deserved five stars, Jun-ha smiled and pressed the tip of the rubber nozzle to Heo Seong-ah’s pussy.
“Ahut..!”
It was soft and rubbery, but still stung like a needle prick.
Jun-ha smeared her juices over the nozzle’s tip,
and every time he intentionally brushed her clitoris, her thighs quivered enticingly.
“Stay still I’m putting it in now.”
“Ah… aaah… Ma-Master!!”
The thin rubber nozzle, about the size of a pencil lead, slipped into the tight little urethral opening.
It was similar to the catheters used in hospitals, so shouldn’t hurt much, but the bizarre new sensation terrified her.
“Aaaaaaah..!”
The deeper it went, the more disorienting it felt, and her hunched back prickled with goosebumps.
Losing her grip, Heo Seong-ah pushed up with her palms as if to raise her torso.
“Sigh… Seong-ah. Spread your pussy again.”
“Auh… it… it feels weird…”
“That’s always how it is the first time. We haven’t even started yet, so what are you complaining about?”
With a glance, Jun-ha pointed to the urethral plug, easily three times thicker than the nozzle.
He’d chosen the smallest one for her, as a beginner.
His plan was to gradually expand her urethra until, six months from now, it’d stretch to fit a pinky finger.
“Kkeuuuuk… haa…”
Lying prone again, Heo Seong-ah, with difficulty, reached down with numb hands and spread her pussy wide open.
The pulsating, opening-and-closing female hole was put on display in all its lewdness.
Any man would feel obliged to fuck her then and there, but there was still work to do.
“Haaaah!”
The rubber nozzle slid further in, without resistance.
At a certain point, feeling changed, and Jun-ha instinctively knew he’d reached her bladder.
“This is the end, huh.”
“Kkeuk…”
He pinched the nozzle with his fingernails to mark how far in it went.
Now he knew the length of Heo Seong-ah’s urethra he’d have to be careful not to cause injury during future training.
Unlike the vagina or anus, the urethra can’t be lengthened.
