Special Textbook for the Lazy Hero
Click…!
Sonia’s oil-stained finger clicked without the slightest hesitation on a video tagged #Fantasy. The title bloomed large across the center of the screen: Hacking the Slave Walker!
“S… Slave Walker… ♡”
Just reading the words made her throat bob hard. Dry saliva slid down of its own accord.
To Sonia, a Slave Walker was never merely a combat machine. It carried the memory of the day she had been shoved, under circumstances she could not refuse, into the control unit itself—a memory that was both nightmarish and secretly, shamefully sweet.
The recollection brushed through her mind again, and a hot knot of heat gathered low in her belly.
She pressed play. The familiar loading screen flickered past and the main feature began. Blue monitor light washed over her face while every sensation from that day returned with the clarity of yesterday.
The humiliation of stripping completely naked at the flat, emotionless orders of the engineer named Peko. The cold, rigid bite of the electric-shock choker locked around her throat. The merciless clamp of wire arms pinning wrists and ankles. The degrading posture of crouching on all fours like a beast inside the cramped, lightless belly of the Slave Walker.
Ugh…♡
Simply remembering made her body twitch. Even now she could almost feel a faint current leaking from the phantom choker, and her chest prickled with it.
Her nipples swelled hard, pushing against the thin fabric of her loungewear until their shapes stood out unmistakably.
“It… it’s starting…!”
The production values screamed low budget. Unable to secure a real Slave Walker, the machine on screen was little more than a clumsy prop. Yet none of those technical shortcomings could break Sonia’s immersion.
The story opened on a graduation ceremony. A pure, justice-obsessed girl fresh from the academy volunteered herself as a Slave Walker pilot to protect Sky City—a classic setup. By chance she watched a recruitment video for a unit no one else wanted. On screen a pilot stood motionless as a mannequin in a warehouse, sealed inside a glossy black bodysuit designed to receive brainwave signals with perfect efficiency. The girl flushed scarlet and fled.
Curiosity won. She searched online, stumbled across a documentary about Sky City’s dark underbelly, and discovered a twisted sexual preference she had never known she possessed.
The actress on screen murmured, face caught between confusion and fascination:
“Slave… Walker… Unit…? Uh… uh… uuh…?”
Mmm… having actually been inside one myself makes it feel even stranger… The suit Milli wore… it was exactly like that, wasn’t it?
Sonia crunched potato chips and sank deeper. Hypnosis… brainwashing… robotization… modification… drone… every tag that set her heart hammering. She held her breath, determined not to miss a single frame.
“Wow… aaah… so… so sticky, sticky…”
In the room lit only by the monitor’s glow, wet little moans slipped between her lips.
A synthetic female voice, thick with sticky sound effects, began to pour into her ears. The lively, smiling girl from the opening was gone. In her place knelt a figure on the cold training-facility floor, awkwardly groping her own body.
In the end the girl ordered, through an online shop, a full-body black latex bodysuit of the exact type a Slave Walker unit would wear.
Days later the scene cut to her gripping the handle of a heavy iron door labeled Slave Walker Unit Training Center.
“C… can I also be reborn as a Slave Walker unit here…?”

Shyness and perverse anticipation tangled in her voice. In the next shot that girl vanished without a trace.
Only a single “unit” remained, pupils completely unfocused, staring blankly at the wall. The latex suit molded every curve so perfectly that personality and individuality seemed erased.
A finger pressed hard against her forehead. A mechanical voice answered like a recording:
“Yes. Master. Slave Walker Unit. Moving.”
The controller in the pilot-actress’s hand was an obvious cheap prop; her button presses were clumsy. Yet the girl who had become the control unit walked into the Slave Walker’s hatch with machine-precise steps, as though genuine remote signals guided every joint.
Ugh… my heart… is racing… it feels so strange…
Sonia’s hand rose unbidden to her full breasts. Her pulse hammered as if synchronized with the girl on screen.
With every passing minute the image of the lively academy student faded into a faint afterimage. What filled the empty space was nothing but a living accessory that responded only to pilot and mechanic commands.
“Detected Master’s arousal… Shall I execute the lust-processing program, Master?… Command received… Beginning masturbation…♡”
…♡ …?! …♡ Nn… huuh…♡
Only then did Sonia notice her own fingers gently circling the hard nipples that had already tented her thin top.
The sensation of the day Peko had temporarily converted her into a Slave Walker unit flooded back through every nerve. Humiliation, shame—every negative emotion had been drowned by a strange, overwhelming excitement. The girl on screen now looked like a doll that had abandoned thought entirely.
Finally someone pressed a small crystal into her forehead. She became a perfectly obedient robot, a genuine standby Slave Walker unit.
“Is… is this my preference? The fantasy of becoming a robot…? Closing off mind and feelings and just doing as I’m told… that sort of thing…”
“If it is… then of course there’s no problem entering the Slave Walker Unit Training Center… right…?”
Sonia listened, chest tight, to the monologue spoken alone in an empty room. The director deliberately cross-cut the hopeful graduation scenes with the present, maximizing the cruel contrast.
“Slave Walker Unit. Classification number 629. Reporting successful completion of education. Entrustment location: Slave Walker Armored Unit—”
Thump-thump… The more the girl lost her self, the harder Sonia’s lower belly clenched and the more violently her heart pounded.
As the story advanced, the unit—sealed in a bodysuit so glossy it creaked—was manipulated helplessly under Master’s orders. If she herself became like that… Sonia sank deeper into the swamp of unstoppable fantasy.
Her mind burned hotter. The people who held command authority over the unit. The unreasonable, perverse orders they issued. The girl obeyed everything in silence, nothing more than a living component of the Slave Walker.
True to the title Hacking the Slave Walker!, the plot followed the expected path. While active as a unit the girl took heavy damage from enemy fire and lost consciousness.
Perhaps… Sonia had firmly refused Peko’s request back then, yet if she had accepted… she might have lived through something very like this video as “Slave Walker Unit Sonia.” The thought flickered through her skull.
Si… no… stay away…! Initialization complete… Master authority confirmed. Awaiting commands. Master.
“Oh… so much… uh… uuuh…♡”
Nebulix’s recommendation engine had sniped her tastes with perfect accuracy. It was only the natural result of the AI analyzing every tag she had ever entered and every video she had watched, yet the personalized service was nearly flawless. How flawless?
My… head… a weird scientist stuck a chip in… and I turned into a robot… an emotionless machine… machine… just like a robot…♡
The master authority of the girl who had sworn to protect Sky City was hijacked by an unknown scientist. He even implanted a control chip directly into her brain, transforming her into an absolutely obedient slave robot—a hacked, dominated Slave Walker unit. The subsequent bio-modifications required to make her a “quality product” were simply a bonus.
“Command received. Please wait a moment before use. Master…♥”

“Uh… uuuh…”
In the final shot, under the mad scientist’s orders, the girl reported with vacant eyes while her own fingers stroked the plump mound of her sex that swelled obscenely against the glossy black latex. It was the same girl who, at the beginning, had cheerfully declared, “I’ll protect Sky City!”
The bright smile in academy uniform versus the expressionless present, every contour of nipple and sex outlined by the black suit. The chip embedded in her skull proved she was no longer human, no longer even a Slave Walker unit meant to defend Sky City—only a lewd slave robot.
Click… Without hesitation Sonia added the video to her “Watch Next” list. She mashed the Like button hard.
