Diuretic Torment and the First Enema
As Yamato pressed down relentlessly on her belly, swollen full of the slave training liquid, what Yujin felt was a wave of nausea mingled with an urgent need to urinate. Urinate? Why was she feeling the urge to pee already? She'd drunk a lot of liquid, sure, but not enough to trigger this yet. And besides, this wasn't a normal urge—it was something unnatural.
When Yujin met Yamato's gaze, he was kneading her stomach with a vile, leering glint in his eyes.
"What... what the hell did you feed me?"
Realizing there must be some twisted reason behind his prodding, Yujin snapped at him irritably.
"Feed you? It's nothing special. Just a little diuretic, that's all."
A diuretic—a drug to force excretion. Only then did Yujin grasp his scheme. He'd slipped it into her meal, forcing her to ingest it against her will.
"You... you perverted bastard."
Yesterday, he'd kept her bound all day until she pissed herself. And now, it seemed, he planned to make her do it again—right in front of him. To Yujin, Yamato was clearly a freak obsessed with urine.
"Too bad I missed the show yesterday. Now, piss nice and hard for me."
His rough hands kneaded her abdomen mercilessly. From the moment the diuretic urge hit her lower belly, Yujin began trembling at the waist, her body quivering more and more. Then a sudden storm of urgency crashed over her.
Noticing her legs twitching as if she wanted to cross them, Yamato positioned a cold iron basin beneath her pussy—different from yesterday's.
The chill of the basin against her crotch sent a jolt through her, twisting her lower abdomen in violent spasms. With his right hand, Yamato gently pried apart her labia to help her relieve herself.
A yellow stream of piss spurted from Yujin's urethra. The forceful jet splashed into the iron basin with a plip-plip sound, then roared shaaaa for a long stretch before tapering off.
Once it stopped, Yamato tenderly wiped her pussy with a dry towel, as if polishing a precious gem. Cupping her breast, he murmured,
"Who would've thought the noble wife of Kenchi would piss so freely in front of me? Unimaginable."
"You bastard... you're an incurable pervert..."
"Pervert? That's harsh. Aren't I the one serving you your meals and tending to your piss?"
"A chance like this doesn't come often. The president of a top-ten corporation personally waiting on you hand and foot—something even the Prime Minister couldn't buy."
Yamato gazed contentedly at the basin filled with Yujin's urine. Then he started kneading her belly again.
"Wh-what? There's nothing left."
And indeed, during her urination, he'd massaged her so thoroughly that no more piss remained. But Yamato's eyes gleamed with a different hunger as he kneaded mercilessly.
Suddenly, a pffft erupted from Yujin's asshole, accompanied by the inevitable sour stench.
Her face flushed crimson at the sound. Yamato's eyes lit up triumphantly.
"There it is—finally."
As if he'd been waiting for her fart all along.
"No signal while you were pissing like that? Suspicious. But now the signal's come."
Licking his lips greedily, he fetched another basin filled with white liquid. Beside it lay a transparent syringe. Yujin's face hardened in dread.
"Please... anything but that... please!"
She begged with a desperation she'd never shown before. But Yamato ignored her, filling the syringe with the white fluid.
Once it was full, he approached her side.
"It's necessary anyway—for training your asshole."
He flipped a lever on the chair, tilting it backward while keeping her seated. Clunk—her hair brushed the floor before he stopped it.
Her position hadn't changed much: legs splayed in an M-shape, breasts bound tight, red ball gag still stuffed in her mouth. Only the angle had shifted. Her once-upright head now lolled precariously against the chair, hair dragging on the ground like a rag.
Yamato inserted a small tube into her nostril.
"If you feel like you can't breathe, this tube will help."
He secured it with a bandage under her nose, then blindfolded her with a large eyepatch covering half her face.
Now tilted at an angle like she was half-reclining, Yujin's ample breasts still thrust out proudly. Bound by ropes and naturally massive, they defied gravity.
Cut off from sight, she trembled violently, perhaps sensing what was coming.
Trapped in darkness, she felt Yamato's finger brush near her anus—her asshole. She jolted harder than usual, moaning through the gag. Saliva dribbled from the edges in shock.
Finding it adorable, Yamato smirked and kept rubbing around her asshole. He could feel it puckering and twitching.
Noticing her clit stiffening too, he carefully produced a small tool: an anal plug, designed to torment the ass. But this one had a hole drilled through the center. And its tip glistened with some shiny lubricant.
He pressed it against her asshole and pushed. Twisting it in circles, he forced it deeper. Yujin convulsed like she was going mad.
"Ogogogok!"
"Don't make weird noises. You'll do this every day—get used to it."
The sensation of her ass stretching, something invading by force, was enough to wrench her body. Saliva poured from her mouth in a flood.
Once the plug was seated like a decoration in her asshole, he threaded a rubber hose through its hole. Pushing it deep inside, he attached the syringe from earlier to the other end.
As he depressed the massive 2L-plus syringe, Yujin let out a grotesque wail.
"Hunggggruk!"
"Nnghheeeuk."
For the duration of the liquid flooding in, she emitted bizarre moans. Being a passage for excretion, the pain was excruciating.
Yamato didn't stop, no matter her cries—just like when she'd gulped down the earlier liquid. Her belly slowly swelled again, gurgling glorp-glorp as it bloated.
By the time the syringe held just over 1L, the pressure made it hard to push. But Yamato forced it with his iron grip. Her screams were inevitable.
Finally, all the liquid was in. He yanked out the hose and sealed the plug tight. A few drops of enema fluid still leaked from the tiny gaps.
Panting raggedly, Yujin glared at him with dying eyes. The urge to defecate surged fiercely.
In normal circumstances, she'd clench her legs and hold it. But now, that was impossible—the demon had bound her helpless.
"Please... let me go to the bathroom..."
Her plea was heartfelt, but Yamato just grinned.
"Untie me! Let me go to the fucking bathroom!"
She'd endured humiliation already, but shitting in front of this man? No. Desperate to hold it, she writhed her whole body.
Yamato savored the sight. Her plump ass jiggling side to side was a delightful spectacle. Her feelings? Irrelevant.
As she thrashed to endure, white foam bubbled from her mouth. Instinct told Yamato not to push further.
He unlocked the plug and placed a small toy toilet—meant for kids' play—in front of her pussy.
"Lock's off. Let it all out nice and easy."
"Uhng... euk... erh..."
Swallowing moans, her face contorted. With a glorp, the anal plug shot out entirely, and the expulsion began.
Thankfully, it stayed contained in the toy toilet. At the same time, Yamato untied the ropes binding her body. He tossed her into a bathtub in the basement corner and hosed her down.
"From now on, once a day: mealtime, bathroom time, bath time. Miss it, and you'll suffer—remember that."
He blasted high-pressure water at her pussy and nipples—painful as hell. Then he lathered soap and scrubbed every inch.
Drying her with a towel, he said,
"Piss, meals, and now baths— you're one lucky bitch."
After patting her dry, he dusted powder everywhere. As he spread it, he suddenly shoved a finger into her asshole. Yujin yelped in panic.
"Don't worry. I'll develop this slowly. No plans to rip it open like a beast."
His thick finger slowly violated her asshole, hooking deep inside, twisting like a corkscrew before pulling out.
"Now, what else do you want me to do for you?"
