The panting sounds near his ear had left Seungjun trembling in terror. The robotic dog, which had been shoving its nose against the nape of his neck and sniffing aggressively, finally pulled away—a sign that user recognition was complete. Now, the robot would recognize Seungjun as a mating target, and once sex mode activated, it would automatically seek him out, mount him, and move on its own. Since it was a machine, it identified Seungjun not by scent but through voice, movement, and other non-olfactory methods. Still, Hyeontae found it ingenious how they’d programmed it to act like it was sniffing him. As this was an unreleased test product, even Hyeontae didn’t know all its functions and effects in detail.
“Ah… Nnngh, hah—! Kuh—!”
The dog, now fully in sex mode, shoved its nose between Seungjun’s buttocks and sniffed loudly. The warm breath against his skin made Seungjun jerk forward, his body shuddering.
“Grrrr…”
Growling like a real beast, the dog began licking its “female” with its tongue. A slightly viscous, saliva-like fluid dripped into the cleft of Seungjun’s ass. Of course, it wasn’t real saliva—just a lukewarm liquid from inside the machine’s mechanisms. But the sensation was eerily lifelike, as if a real dog were lapping at him. Seungjun’s tears spilled over. The feeling was horrifying. Streaks of tears stained his cheeks.
The dog’s “saliva” was a diluted version of the same love gel with aphrodisiac effects as the slime had been. The robot meticulously, almost affectionately, lapped at Seungjun’s anus, occasionally flicking its tongue around his balls in panting breaths. Seungjun froze in terror—what if he resisted? Would the thing bite his dick off?
“Hah… ugh, ah, nngh—!”
The dog’s long tongue invaded his anus, forcing its way into the tight space. The deeper it burrowed, the more an unfamiliar, hot, ticklish sensation spread through his body.
“Kuh… grrr…”
When the tongue retreated, his hole twitched. It was his first time being stimulated there, and the aphrodisiac had him burning with arousal. Seungjun writhed, confused and miserable, his insides scorching and itching. The dog placed its front paws on his back and began panting louder. A bright red dildo, slick with clear fluid, emerged from its body. Hyeontae knew it was just a mechanical appendage, but to Seungjun—who had no idea it was a robot—it looked like the dog was dripping pre-cum, its swollen red cock rubbing against his ass crack. And then, horrifyingly, it began to disappear between his cheeks. The stretching sensation made him scream.
“Ugh—! Uuuu—! Kuhh—!”
It was a sound somewhere between a scream and a sob. As the dog’s “cock” forced its way inside, Seungjun dry-heaved repeatedly. He loved animals, but this—being fucked by one—was something he’d never even imagined. Yet despite the revulsion, he couldn’t bring himself to run. The way it scraped against his inner walls as it pushed in sent shivers of pleasure through him. His own erection throbbed as he was penetrated by the machine. Panting, his thighs trembled. Had he really turned into a bitch? If not, why did being railed by a dog’s dick feel so good? He wanted to stop, but another thought clawed at him: If I don’t mate with it like this, will I ever turn back into a human? He wished someone would tell him this was all just a dream. He could feel the dog’s hot “cock” buried to the hilt inside him. One thought dominated his mind:
I’d rather die.
Fear, shame, and anxiety crashed over him in waves. The dog began to move, and he felt it pulling out—an urge to vomit surged up his throat. His vision swam. He squeezed his eyes shut. Tears streamed down his face. Lowering his head, he saw his own hands pressed against the floor. To Hyeontae, they looked pale, knuckles starkly visible. But in Seungjun’s eyes, his hands were covered in thick fur—paws.
The realization that the curse had fully transformed him into a dog shattered what was left of his sanity. Behind him, the male dog panted as it thrust its hips wildly. Even after seeing his own paws, he couldn’t believe it.
“Auu—! Ah—! Kyaa—!”
Since he wasn’t actually a dog, the sounds he made were still human-like—just incoherent. The robot, however, was programmed to fuck like a real dog in heat, ramming into him without restraint.
Impressive work.
That was Hyeontae’s conclusion as he watched Seungjun being bred. This product was market-ready. People would love the idea of a “safe” sex dog—no risk of infection, no real animal cruelty. Just pure, mechanical satisfaction. And the technology was remarkable: balancing on four legs was hard enough, but to do that and fuck? Truly groundbreaking. Hyeontae was too absorbed in evaluating the product to spare a thought for Seungjun’s mental trauma. The dog let out a low growl, then pumped its load deep inside him.
“Ah—! Ugh, ah—!”
The sensation of cum flooding his insides made him grimace—then his face twisted in pain as he collapsed forward, his hypnosis-induced quadrupedal stance finally giving out. He managed to keep his ass in the air, face flushed, panting.
“Knot, huh?”
Hyeontae knew they’d put significant effort into mimicking real dog mating. The tip of the dildo must be inflating, just like a real knot. He nodded in approval. The dog turned around, presenting its hindquarters. Every movement was precise. To Seungjun, that precision was terrifying. Suddenly, the thing inside him expanded, and he let out a choked whimper.
The pain was so intense it drowned out his fear. Hyeontae, considering how extreme this was for a virgin, decided to intervene slightly.
“Seungjun.”
He got up from the sofa and approached. Seungjun’s hair was soaked with sweat.
“Ugh… uuu—”
At the touch of a comforting hand, tears spilled from Seungjun’s eyes. The warmth of human contact made the loneliness crash over him like a wave.
“You did well. That’s one mating down. Don’t forget the count… Seungjun, a bitch loves being knotted, remember? Why are you crying?”
“Huh… sniff—”
“You might even get pregnant from this. You should enjoy the mating… Seungjun, a bitch doesn’t think as clearly as a human. You’re just sad because you’re clinging to your human memories.”
Hyeontae personally wiped away Seungjun’s tears. Seungjun sniffled, his breath hitching, his face a picture of misery.
“Can you remember everything from when you were human? No, right? Seungjun, what you should focus on now isn’t your feelings. You’re a bitch. A bitch that drools and wags its tail when it gets dog dick. A bitch obsessed with dog cock.”
He repeated “bitch” like a mantra, reinforcing the suggestion. Watching Seungjun pant, Hyeontae stood up.
“Hyeonjun, did you finish your assignment?”
“No…”
“Take a break, then do it.”
Hyeontae knocked on Hyeonjun’s door. A small voice answered from inside, and at the suggestion of a break, Hyeonjun opened the door, naked except for the rose tattoo blooming across his skin. Hyeontae flicked one of his nipple piercings playfully.
“Ah! Daddy—!”
Hyeonjun glared, as if to say stop teasing. When he wasn’t aroused, the hypnosis scent only made him sullen, not submissive. Of course, his defiance existed within the bounds of his warped reality—where none of this struck him as abnormal. Maybe his idealized vision of a “good wife” was a demure one, a reaction to the cold, neglectful mother he’d had growing up. But that wasn’t the priority now.
“Anyway,” Hyeontae said, guiding Hyeonjun to the living room to cool off, “let’s give him a break.”
Seungjun was still on the floor, knotted by the dog.
“Uh…?”
“One dog alone would be lonely, don’t you think? Left to guard the house all day… So I got a female too. Her name’s Seungjun—same as your friend, huh?”
“Um… but why in the living room…?”
“Mating is natural for dogs. Who knows? Maybe we’ll have cute puppies. Best not to disturb them during.”
He introduced Seungjun as the new “female dog” with ease. The confusion on Hyeonjun’s face faded quickly—his eyes now saw Seungjun as just another bitch in heat.
“Now, Hyeonjun. If the dog’s working so hard to get pregnant, shouldn’t you try harder too?”
Hyeontae sat on the sofa, patting his thigh with a smirk. Hyeonjun, now conditioned, grumbled but climbed onto him anyway.
