Real Doll's Protect Mode Breached

Real Doll (21) "What the hell is this? Why does it feel so damn good? I can't think straight!" Isia couldn't spit out any of the lines she'd rehearsed in her mind. Instead, she let out pig-like squeals while clutching her head with both hands. Get it together, get it together. She couldn't collapse like this.

This guy's not my master. My master is ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Jingoo. My husband, Oh Jingoo, right?

Real Dolls had a bizarre function that let them access their internal network like a computer. Real Doll Number 77 connected to the circuit chip in her brain and checked the master registration info.

Good. It was definitely registered. The surgery had been a success. So why...

"Does my pussy feel this fucking good♡ Goooood♡"

"Hey, your snot's dripping."

"I don't have time to worry about thaaat♡"

Every time his cock thrust in, her consciousness flew away and snapped back. It felt so good it was beyond pleasure— she was on the verge of blacking out. And above all, this dick showed no signs of going soft no matter how much time passed. If anything, it was getting harder.

"Wait♡ Just give me a break for a sec♡ Please! I've already cum five times♡ That means I get a rest, right♡"

"I haven't even cum once yet?"

"Wha...? No way... that's... impossible."

Seeing his smug grin, Isia recoiled in shock. A Real Doll's vaginal walls were designed to suck and caress the cock like a vacuum cleaner the moment it entered. Jingoo couldn't last three seconds in her, but this guy had been holding out for over ten minutes? And... that relaxed expression—what the hell?

How superior is this stud?

"Why're you looking at me with that slutty face, senpai?"

"...Ngh♡ Wh-who's sluuu♡"

"My cock's better than Jingoo's, right?"

"Sh-shut up!"

Still putting up a fight, huh. Even with drool pouring from her mouth. No helping it. Maybe pinch her clit—she'd get honest then.

"You still not gonna admit it?"

"Feels so gooood♡ Y-you touch my clit and of course it feels good♡ Ahh♡"

"Why not just go back to being my slave like old times?"

"Sh-shut uuuup♡"

Dangerous.

This is seriously dangerous.

My pussy's starting to mistake this monster cock for Master's on its own.

At this rate, she'd end up kneeling before Kim Hoyoung and fawning over him again. What could she do? A head-on fight was hopeless. She hated to admit it, but that cock of his was top-tier perfection. Undeniable. No woman could resist it. No one. Ever!

That's it!

Suddenly, Isia recalled her first time having sex with Oh Jingoo. When his cock— not her master's—entered her, her sense of self faded, Protect Mode activated, blocking all sensations and moving her body to defend against the intrusion. Kim Hoyoung had disabled it now, but... what if she reactivated it?

Protect... Protect...

She scanned her brain circuits again. Flipped the Protect Mode switch from off to on.

Done.

Now I can push out Kim Hoyoung's cock!

"Huh? Why's your voice like that, senpai? Sounds all robotic?"

Isia didn't respond. Her eyes had lost focus, her mouth slack like a corpse's. She was no longer human—just a thorough Real Doll operating on program. No reaction to touches, slaps, or pinches. Blank expression. This was the ironclad defense she'd wanted.

When a non-master cock entered, a Real Doll first reinforced its full-body coating to block contact with the penis. A safeguard for purity.

"What're you doing, senpai?"

But things didn't go smoothly from the start. The silicone coating couldn't withstand the steel-hard glans bombardment and tore apart.

Her robotic face flushed pink. The vaginal walls were exposed to the cock's assault again, the coating tearing chain-reaction style all the way to her labia. When Kim Hoyoung's hand touched her breast, that coating melted too. A kiss, and her lips grew slick with saliva. The coating was now a meaningless barrier.

To expel the semen inside, she generated special carbonated fluid from her womb and sent it down, but there was too much cum—way more than expected—and her own love juices kept flowing nonstop, so it didn't work.

"No idea what pointless crap you've been trying since earlier. Just give me your lips."

Kim Hoyoung hugged the Real Doll, lifted her up, and roughly claimed her mouth. Isia gushed nosebleed. Her arousal hit max, glitches starting in her body.

Th-this monster! Even Protect Mode's useless?! Isia screamed internally. But that wasn't the only ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠problem. Kim Hoyoung's monster cock pierced her vaginal walls, passed her cervix, and plunged in and out of her womb in full-on uterine sex. Jingoo couldn't dream of this, nor could any other man.

Womb feels so gooood♡ Can't take a cock going in my womb♡ If I get addicted to uterine sex... I-I won't be satisfied without Kim Hoyoung's cock anymore! I have to stop thaaat!

"Quit bullshitting—I'm gonna cum in your womb, so take my seed."

Protect Mode covered up to the vaginal walls. Sex crossing the cervix was out of bounds. Kim Hoyoung's cock finally blasted semen straight into her womb. So much it filled her up, belly bulging.

Isia convulsed visibly, eyes rolling wildly, circuits sizzling audibly from her body. Lips quivering, teeth chattering as she gnashed at air, limbs jerking violently.

Isia's neck snapped awkwardly like a robot's. Her blank face made it even creepier.

"Oops. Wasn't planning to knock you up. But Real Dolls progress this fast? Anyway... why the overreaction?"

Isia's eyes turned bright red, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠like emergency lights. Her body even beeped warnings nonstop.

Real Doll Number 77 followed company programming, switching her registered master from 'Oh Jingoo' to 'Kim Hoyoung' to avert self-destruct. Impregnated by a non-master was the ultimate crime—all Real Dolls were programmed to explode on-site. But a master's child? No issue.

Isia's body shuddered, glowing faintly. Watching her, I thought she looked just like someone on a massage chair. "Aduuuuuhhh."

"Isia noona! Isia noona, you here, right?!" Right on cue, Oh Jingoo burst into the bedroom, tracking his missing lover. He'd checked everywhere related to himself but found no wife, so this was his last spot. Seeing his naked wife trembling on the floor, he freaked.

"Noona! Isia noona! Wh-what happened! What the he—...!"

To him, his patching wife looked like Isia, raped by me and lost in shock, collapsed. The timid guy flushed red, clenched his fists, and charged.

"K-Kim Hoyoung! You bastard! You've been the root of all this from the start!"

"Hey, chill. I even gave Isia back to you once. After buying her for 10 billion each, no less."

"Shut up! H-how many times did you rape Isia noona! I only did it o-once...!"

He grabbed my collar for the first time in ages. Choking. Jingoo raised his fist high. Gonna punch me? Maybe let him land one? Or fight back? Street fight. Haven't done one since middle school. And I wasn't even mad enough at Jingoo to want a brawl. Eh, whatever—just take one hit. He's no Tyson; my jaw won't fly off.

I shut my eyes, ready to eat a punch.

"Die, you motherfucker! Take thiiiis you fuaaaack!! Uwaaaaaah!"

But it flew. Not my jaw—his hand. Jingoo's, of course. Why's the scream so long? I opened my eyes to see his tiny hand spraying red blood, floating mid-air before splatting on the floor.

"Uwaaaah! Aaaah!!"

Jingoo clutched his wrist and flopped down. Whoa. That looks brutal. What the hell?

"How dare you lay a hand on Master. Insolent fool. As long as Real Doll Number 77 draws breath, no one harms Master."

"Whoa... patch done, senpai?"

Isia senpai sheathed her bloodied sword (Kunitora, was it?) like a samurai, declaring solemnly. She glared icily at her writhing lover—legally still her husband—then lit up at my voice, dropping to her knees.

"Yes, Master♡ That's right! Real Doll Number 77 has finally come to her senses♡ I repent for my insolence, rebelling against Your greatness all this time♡ Please let me live as a tool used for Your pleasure, sucked dry then discarded like chewed gum when the sweetness fades♡"

She rubbed her cheek against my palm like a puppy, groveling shamelessly. Jingoo's wails from afar didn't reach her. Desperate for my attention, she kissed my instep, swearing loyalty over and over.
