Slave Walker
“That’s right. The monitor shows a normal connection. Is there a problem? Does it hurt?”
Peko’s calm, emotionless voice reached her. All Sonia could manage in reply was a faint, broken murmur of “Ah… n-no…”
A simple order to move forward arrived as two sensations at once—a choking grip of absolute submission around her throat and a piercing jolt of pleasure that drove straight through her womb. This was the Slave Walker’s method of control.
Hngh… haah… ahh…♡ At this rate… I’ll really… end up becoming a slave… just like Milli, who went into a Slave Walker…♡
For a girl who normally sprawled in her room with lewd videos playing, legs propped on the desk while she idly fondled her own enormous breasts, the sensation of a foreign object writhing inside her body and issuing commands completely independent of her will was overwhelmingly intense.
Her toes curled of their own accord. Her waist dipped into a sharp, elegant arch.
Between Sonia’s thighs, she was already soaked far beyond any need for extra lubricant. Clear, slippery nectar slid down her smoothly shaved sex and pooled in a small puddle on the cold metal floor beneath her.
“Moving forward is that sensation you just felt. This time it’s a direction change, so remember it well.”
“Ah… understood! Ma… uh… Peko!”
When Peko lightly pressed the control stick to the right, the choker around Sonia’s neck tugged in the same direction. A fraction of a second earlier, however, the control unit buried inside her gently stroked the right-hand wall of her passage. Before her rational mind could even register the pull of the leash and decide “I must turn right,” the direct signal from within her body had already twisted her hips reflexively to the right.
“You’re doing well. Really impressive, Sonia. You have the makings of the finest unit.”
“Th-thank you…♡ Hngh…♡”
Sweet praise arrived together with the signal to turn left. Once again the control unit found the most sensitive spot on her left side and stimulated it with perfect precision before the choker even moved.
A sharp jolt of pleasure made Sonia’s body flinch and swing left on pure reflex. Her full breasts swayed violently with the motion; the stiff, erect nipples brushed the floor and sent fresh sparks of sensation through her.
Inside the dark, cramped belly of the four-legged war machine, on all fours exactly like the machine itself, wearing a metal choker that marked her as property, every hair on her body meticulously removed so that she was nothing but smooth bare skin, Sonia was becoming a living component that obeyed Peko’s every command—a true Slave Unit.
“Very good. This time we’re going to dash. It’s the movement you use to break away from enemies or to charge. When you run, it feels like this!”
Thrust! Peko snapped the joystick forward twice in rapid succession. The signal that reached Sonia was incomparably deeper and more intense than anything before.
The control unit went beyond mere pressure; it drove hard and deep, as if trying to spear the very core of her.
“Ahiit…♡♡♡!”
Exactly like a racehorse that bolts the instant the whip cracks, Sonia’s body shot forward in a wild lunge, driven by the violent pleasure that rocked her womb.
One step. Another step. With every command from Peko, an obscene, shameful, yet irresistibly delicious sensation began to dominate every inch of Sonia’s body.
Thanks to the sedation pad stuck to her forehead, the very concept of resistance had already slipped from her mind. Vacant golden eyes and a blissful little smile were all that remained as she surrendered completely to the feeling of the control rod stirring inside her.
“You’re doing wonderfully, Sonia. I’ll start preparing for actual combat soon. One last test. You’re doing so well, so don’t tense up.”
“…Ah… understood…! …Ngh…!”
They say praise can make even a whale dance. The moment Peko’s gentle compliment reached her, the control unit inside Sonia vibrated lightly, sending a pleasant ripple of stimulation through her—exactly like a master stroking the back of a loyal pet. Positive reinforcement. The most effective training method hard-coded into the system.
“Good. From here on we’re going to smash every last one of those stupid drones as we go, so hang in there, Sonia!”
“Please take care of me, Peko! …Ngh…♡”
“Likewise—I’m counting on you, Sonia.”
…If things go well… I might just end up with a brand-new Walker unit…
Peko adjusted the vinyl backpack on her shoulders—the one that held her precious little sister—and allowed a faint smile to touch her lips.
Sonia’s limbs no longer passed through any process of thought or appreciation of sensation. They reacted to Peko’s signals with less than a tenth of a second of lag. Even to a veteran pilot like Peko, the synchronization was astonishingly perfect—as if Sonia had been born from the start to be a component of this very Walker.
“See what’s right in front of you, Sonia?”
“Yes, I can see it clearly! What should I do now?”
Far down the dark corridor, terrorist drones drifted in the air, still unaware of them. The Slave Walker kept its massive bulk hidden in the shadows, quietly waiting for the perfect moment.
“Keep staring at that drone exactly like that, Sonia! Don’t look anywhere else! Got it?!”
“Yes… yes…! Ah… got it, Peko!”
The instant Sonia poured every scrap of her consciousness into locking her gaze on the drone ahead, a large red targeting circle bloomed across the display floating in her vision. As she held her stare, the circle steadily shrank until it became a single laser-pointer-like red dot. The Walker’s optical sensors and Sonia’s own eyes had linked perfectly and locked onto the target.
“Then—fire! Feel this sensation carefully, Sonia! This is your new role!”
Press. Peko’s slender thumb jammed down hard on the red fire button—the one that already showed the most wear from constant use.
Crackling! Sparkling!
The moment the button depressed, a powerful, electric thrill exploded outward from the exact place deep inside Sonia where the control unit was seated.
The screen before her eyes flooded pure white with the flash at the same instant her body convulsed as violently as if she had just experienced her first orgasm. Her back arched like a drawn bow; a meaningless, high cry tore from her throat.
Wh… what…?
Sonia’s golden eyes could not even close. After the flash faded, not a single afterimage remained. The specially treated contact lenses fitted over her eyes had completely blocked every harmful ray. Far ahead in her vision, the drone that had been floating only a second earlier burst apart in a shower of sparks and debris.
Whirrr… shhhk… shhk…
The faint servo-motor sounds of the laser launcher opening on the Walker’s upper turret brushed past Sonia’s hearing.
A beam of red particle light filled her entire field of view, searing the air with heat; a faint ozone tang stabbed into her nostrils.
Closing her eyes was never an option, yet the special contact lenses covering her eyeballs protected the optic nerves so thoroughly that not even an afterimage lingered.
The crimson ray that split the pitch-black darkness grazed past the target combat walker’s laser mount and drove cleanly through its power core.
“Good. You’re getting better and better, Sonia.”
Peko’s calm, satisfied voice slid gently into Sonia’s ear through the comms.
Praise. The most primitive and most effective reward system worked directly on Sonia’s mind.
“Th-thank you! Ma… st… Peko!”
Sonia hastily swallowed the word of submission that had almost slipped off the tip of her tongue.
Even though she had forced it back down, her cheeks were already burning apple-red and her hot, ragged breaths were raising the temperature inside the cockpit, broadcasting her arousal without mercy.
Only moments earlier the unmanned craft had been lazily patrolling the skies of Sky City, flaunting its threatening presence. The red laser that Sonia had locked onto with her gaze and that Peko had fired had punched straight through it and brought it down.
Boom…!
The explosion itself sounded dry, yet the laser had precisely pierced the drone’s power core and rendered it uncontrollable. Because the weapon was weaker than Sonia’s own plasma pistol, the machine did not shatter mid-air into a thousand pieces.
Instead the lifeless hunk of metal, stripped of all thrust, lost its fight against gravity and plummeted in a clean parabola. It smashed through the reinforced glass of the first and second floors of the building beside the road and detonated a second time.
Sonia looked ready to flood the channel with questions again, but this time Peko spoke first. In the same calm tone one might use to teach a green recruit the basics of a control system, she began explaining exactly what had just happened and why.
That’s right. I need to make her properly understand who is currently riding inside this Slave Walker… what role this particular part is supposed to perform.
Peko checked the bio-signal graph on her side of the controls; Sonia’s readings remained stable. She murmured to herself,
The sedation patch seems to be working extremely well… with this level of adaptability she’s already far better than the ones we get from criminal stock…
“That just now was the Walker’s main weapon. The laser launcher mounted on top of the unit aimed and fired a particle beam straight at the target. Pretty amazing, right?”
“Obviously I’m the one who presses the fire button, so don’t feel any pressure, Sonia. There’s only one thing you have to do: keep looking at the target. Then the shot goes exactly where you’re looking. That’s the most basic operating principle of a Walker, so remember it well.”
Peko’s explanation was purely businesslike, yet every word defined Sonia as a perfect biological component.
Sonia had no need to think or decide. She was simply a living, high-performance visual sensor whose only job was to “see.”
“Ah. You already know without me telling you that the red circle shrinking in your vision is the aiming process, right, Sonia? How are you holding up so far? Anything you’re curious about?”
“Ah… n-no. I’m fine. It… was a much stranger experience than I expected… I got flustered, but… you guided me so well, Peko… please take care of me…”
Sonia’s voice trembled faintly. The wet foreign presence of the control core inside her mixed with the electric thrill of the moment of firing, leaving her thoughts in complete disarray.
“Good. I’m glad to hear you say that, Sonia. Then let’s keep going just like this!”
“Yes! Pl-please take care of me! Peko! …Ngh… uuuh…♡”
At Peko’s encouragement the control core vibrated pleasantly once more. Beneath Sonia’s completely depilated, silky-smooth sex, the Slave Walker control core “mounted” in her most sensitive crevice sent a delicate pleasure signal; her body twitched in reflexive response.
Surrendering herself to the lewd sensation rising from deep in her belly, Sonia guided the Slave Walker forward exactly as Peko desired.
