Pet Livestock
"……Nngh?"
As soon as Mitsuki woke up, she saw the gag stuffed in her mouth and began to tremble. "W-what the hell is this!"
Struggling to form words, she writhed in place, and Matsuta approached. "Mitsuki, from today onward, you're a full-fledged bitch in heat. You'll be meeting your new master soon, so try to hold back that excitement just a little."
At the mention of a new master, Mitsuki's body shook violently. Her face drained of color, turning ashen. 'Master? Does that mean... I'm being sold?'
That had been the reason for her bitch training all along, but back then, Mitsuki hadn't been able to think straight. Surviving the sessions had been overwhelming enough.
A familiar face approached the dazed, despairing Mitsuki.
"……Touki?"
Touki. The son of President Tojima, the same age as Mitsuki, and a childhood friend from the neighborhood. Of course, it had been years since they'd last seen each other. Part of it was her time studying abroad, but she'd also distanced herself because she'd sensed his unhealthy gaze on her.
"Mitsuki, to see you again like this... I'm so thrilled, I can barely speak."
He claimed to be thrilled, smiling away, but beneath it lurked a clear sneer at the sight of her reduced to a bitch.
"……This is all your doing! Me ending up like this. My father too!"
Of course, Touki wasn't directly involved. Most of it was the handiwork of Prime Minister Ryosuke and Touki's father, President Tojima. Touki had simply been conveniently chosen to dispose of the now-inconvenient Mitsuki.
Touki had always liked Mitsuki since childhood. At first, he'd thought it was innocent puppy love for a girl his age, but it wasn't. It was pure possessiveness. As the son of Tojima, head of one of Japan's top ten conglomerates, that craving for ownership had been firmly inherited.
And the object of his desire was Mitsuki. He wanted to claim her, mold her to his whims, make her obey his every command. This was his chance.
Touki stepped closer and pinched the tip of Mitsuki's breast.
"Don't touch me! Get your hands off!"
Bound and tugged by her nipple, Mitsuki grimaced and yelled. But Touki merely slapped her cheek hard.
"A bitch daring to defy me?"
Touki immediately handed a thick wad of cash to Matsuda. "I've paid up, so I can do whatever I want now, right?"
Matsuda checked the bills and nodded with a smile. "Of course, sir. If you need help with transport, just say the word."
"Perfect. Package her for sleep, then."
At the words "sleep packaging," Mitsuki lost consciousness. Sedatives had been injected through the tubes embedded in her body.
Touki gazed at her collapsed form with a sadistic grin. The woman he'd coveted for so long was now his—body and soul—as breeding livestock.
"Wake up, Mitsuki."
Mitsuki's eyes fluttered open at the voice calling her. Bright sunlight, a blurry man before her.
"Dad……?"
It felt like emerging from a long, nightmarish dream. But the next words shattered the illusion.
"I said wake up, you bitch slut."
The voice she'd mistaken for her father's belonged to Touki, looming over her.
He held a sharp whip used for training livestock in one hand and wore pointed high heels designed not for walking, but for inflicting pain—unlike ordinary women's heels.
And Mitsuki lay there in the full bitch pose she'd been drilled into, sprawled on the floor.
"Now, shall we start our walk?"
Touki cracked the whip against her ass. With jagged weights at the tip, it bit into her skin, leaving angry red welts on contact.

Desperate to avoid more pain, Mitsuki began to crawl forward. Quadrupedal movement on all fours demanded grueling core strength, especially compared to bipedal walking. It was no different for her. Sweat drenched her body as she inched along slowly.
Watching from behind, Touki eyed her wiggling hips and jabbed the heel's tip into her ass.
Naturally, Mitsuki shrieked in agony, tears welling up. "Eek… Hiiik!"
"I stab your ass, and you squirt pussy juice? What a horny bitch."
Her body, modified for heightened sensitivity, heated up and aroused from even minor stimulation. A heel in the ass registered as excruciating, seizure-inducing torment.
Trails of slick fluid poured from her as she crawled, soaking the floor. And every time, she earned more lashes for "dirtying" the ground. That was Mitsuki's life now.
Their destination was the mansion's grounds. As President Tojima's home, the yard was vast—larger than a typical athletic field.
"We're starting the walk now. I'll call you Mitsuki or bitch. You call me Master."
"……."
"No answer? Let me ask again. What do you call me?"
"……M-Master."
Mitsuki whispered it, voice barely audible, crawling low.
"Too quiet. Want punishment?"
Touki lashed the whip through the air with full force. Whish—crack! The slicing wind made her flinch.
"I'll call you Master!"
Terror gripped her as she glared up at his fierce eyes. Touki looked intensely aroused, yet an overwhelming charisma radiated from him. He was Tojima's son, dubbed the "Tide of the Business World," for good reason.
Touki picked up a small bone. "Good girl, Mitsuki? Smart as you are, just fetch this."
He hurled it to the far end of the garden. Fear of the whip propelled Mitsuki into a sprint after it. Shame and humiliation as a woman? Long gone. She was little more than Touki's pet dog now.
Panting back with the bone in her mouth, sweat poured from her body, pussy juice gushing freely.
Touki stroked her head, then reached for her crotch. "Good job. Time for a reward."
He yanked her tail aside and shoved the bone into her pussy.
"Hiiik! Y-you, too sudden!"
"Bitches don't talk."
"W-woof! Woof!"
"So happy, huh? Knew you'd love it."
As he scraped her insides slowly with the bone, Mitsuki let out delighted yelps. "Woof… Nngh! Ahak♥️, Uguuk♥️."
It should have hurt like hell, but her hypersensitive body welcomed even this as pleasure. Against her will, her pussy clenched happily around the intruding bone.
Touki kept tossing small balls after that, making her fetch like a proper bitch. All day on their "walk," Mitsuki fulfilled her role perfectly until dusk fell.
The next day dawned, and fresh from her doghouse, Mitsuki was ordered on another "walk"—just an excuse to humiliate her.
"Today, circle the garden. Five laps. Late, and you get punished."
Mitsuki pumped her arms and legs furiously, circling the garden. But quadrupedal running strained the human body; she barely managed three laps before tumbling forward.
Touki approached with the whip, of course. "Bad habits already, bitch?"
"Woof… Master… I can't run anymore…."
"No such thing. When I say run, you run."
Touki kicked her prone belly hard with his foot.
"Woof… Nghk…!"
Choking pain seized her, her lower abdomen quivering. Drool spilled as she looked up at him.
"Do you know how much I paid for you? Can't slack off already."
He yanked savagely on her collar. Her throat constricted, breath cut off; she howled like a beast. "……C-can't… breathe! P-please, mercy!"
"Be good from now on?"
The tension eased from his grip, the choking pain vanishing. But the terror of asphyxiation lingered deep in her body.
Trickle, trickle. Hot, yellow piss streamed down her thighs.
