Slave Training
"I heard she was once a noble lady, but her behavior tells a different story. To react so immediately just because it feels good."
Yujin's clitoris was swollen like a rocket primed for launch at any second. Kimiro teased her core with his lips and front teeth, nibbling away relentlessly. The moment his front teeth grazed the rigidly erect nub, an electric jolt surged through Yujin's body, making her tremble violently from head to toe. It was worlds apart from Yamato's sucking. If Yamato's approach was brute force, Kimiro's was the slow, deliberate build-up that knew exactly how to coax out shivers of ecstasy.
He kept at it for several minutes, sucking on her clitoris without mercy. Yujin was already lost, her lips parted blankly as drool dripped from the corners of her mouth.
"Haah... haaht..."
Unrestrained moans spilled out. Only then did Kimiro lift his head and meet Yamato's gaze.
"President, I've tested her body's sensitivity first, and it's undoubtedly top-grade."
"Is that so? Then how far along is she?"
"Probably no more than a month, even at the longest. For premium training like this, it's all about relentless intensity. From here on, I'll proceed my way."
"Do as you please."
"Very well, then."
Kimiro immediately inserted a thin hose into Yujin's nostril. They were starting training without sleep from now on, but he didn't want her collapsing from malnutrition, so he'd hooked her up as a precaution. Of course, the influx of nutrients through her nose was part of the training too—it made breathing difficult, allowing him to control her submission through respiration.
Next, he gagged her mouth. Then he snapped the chains on the handcuffs binding her arms. In their place, he tightly bound a white cord around her swollen nipples, which were engorged enough to serve as perfect anchors. The short cord reconnected to her cuffs.
"Perfect. What a beautiful sight."
Now Yujin could no longer lower her arms. Lifting them stretched her nipples to their breaking point. It wasn't just that—any twitch of her wrists sent sharp jolts through her nipples.
"Hngh... hngh..."
Kimiro picked up the wooden tool Yamato had demonstrated earlier. He twisted the thick end against her vaginal entrance before plunging it deep into her mucosa. Her lower belly bulged inward with a squelch, and Yujin arched her back like a bow, letting out a piercing scream. She wanted to resist, but her pussy clenched fiercely around the invading wood, like seaweed gripping something underwater. Kimiro marveled at the freakishly powerful contractions—the strongest he'd ever seen.
"A true masterpiece right down to the depths. I can get even rougher, then."
He spun the wooden tool voraciously as he spoke.
"Clench tighter, you bitch."
Her vaginal walls wrapped and squeezed the tool in response. Midway through the back-and-forth thrusting, Kimiro carefully pressed down on her clitoris with his other hand. Pinching the rock-hard nub made Yujin buck her hips and cry out.
"No more... I can't take it... I can't hold back."
With that, a fierce jet of fluid gushed from her pussy—squirting, not urine. It was something she'd never done, not even after dozens of orgasms under Yamato. He watched Kimiro's training in his usual awe; it was like art. Once the sensation was etched in, forced climaxes chained endlessly. Yujin lost all strength after hours of them.
Then Kimiro wrapped rope tightly around one thigh and hoisted that leg up, shifting her pose. Only one foot barely touched the floor now, the rest dangling in urgent suspension. Her breasts remained bound to emphasize them, the gag still in place.
He produced a dildo whose head spun viciously and drove it straight into her crotch without preamble.
"From now on, take it obediently. Every time you resist, I'll ream your asshole. I've already mapped all your weak spots—I'll develop them thoroughly."
With a sinister grin, Kimiro tugged the ropes. Unlike Yamato's amateur bindings, these dug into her like a single connected web, stimulating her pussy, breasts, armpits, and thighs intensely. Yujin flailed like meat tossed into boiling water.
"President, I've learned a truth through my training. Do you know what it is?"
"What?"
"Any toy—or pup—that doesn't have pain and fear branded into its body will one day bite its master."
Pulling the rope connected to the pulley lifted her other foot too. Now she balanced only on tiptoes, utterly helpless. The massive spinning dildo at her entrance slammed into her vagina, rotating so fiercely it seemed to churn her walls.
"Hggguuuuaaaah!!!"
This scream was pure agony, unlike before. Yujin summoned every ounce of strength left in her. Her entrance felt twisted and mangled, the pain vibrating through her walls nearly flipping her inside out. She'd once thought that even if raped, a woman's body would inevitably milk the intruder. Wrong. When tormented without respite, that didn't apply. Sleep fled entirely. Between her legs burned like a red-hot iron rod, unprecedented pain paired with girth that stretched her limits. Nothing this thick had ever entered her—adult forearm-sized. Terror flooded her: would her pussy tear? Maybe it already had, blood trickling out.
Kimiro was a savage beast. To him, a woman's body was prime prey, and Yujin was the finest he'd ever hunted.
"Even in pain, your pussy quivers. What a filthy masochist."
Words to shame her. Yujin wanted to protest, but every attempt to speak brought waist spasms and tearing agony, birthing only screams. Instead of denial, pleas escaped: "Stop, please."
"It hurts too much. I'll break like this... please stop."
Even honorifics slipped out in desperation. But it only fueled Kimiro's sadism. He twisted her pussy like an onahole, merciless, a brutal violation without pity or pause. The basement filled with squelching noises and Yujin's pained moans. Her begging seemed to spur him; apologies and cries for mercy made his hands move faster. She repeated "spare me" like a machine. The dildo, thicker than his forearm, buried to the hilt repeatedly, forcing orgasms amid the ruin. As its churning grew wilder, her resistance dissolved into sobs. Thrashing her arms in pain tugged her nipples, blending torment with unwanted pleasure. Pleasure birthed pain, pain pleasure—a vicious cycle.
By now, Yujin might have begged to be fucked. But no—her last shred of pride held. The high-raised leg and splayed pose amplified her humiliation, breaking her from within. She wailed, flooding the floor with a torrent of fluids in a full-body climax. Utterly spent, she slumped like a broken doll.
Only then did Kimiro release her from the ropes, lowering her to the floor. Pulling out the dildo revealed her crotch swollen beet-red. To Yujin, her entrance gaped wide. Untying the nipple cords left them flushed and ravaged from the strain. Yamato eyed it worriedly.
"At this rate, she won't last through more training."
"No, she'll be fine. Next up is developing her rear hole."
At "rear hole," Yamato grinned. He had a perverse fondness for it, after all.
