Chapter 6: Ultimate Upgrade
The memory of the barracks was a warm, sticky film on her skin, a phantom soreness in her jaw and a deep, satisfied ache in her vault. It clung to her as she navigated the morning grime of the city, a private smile playing on her lips. The promise of tonight—the whole squad—hummed in her veins like a shot of cheap stim. But first, she needed an upgrade. Celebrations deserved a spectacle.
Ripper’s clinic was in a permanent state of chaotic functionality. The sterile glow of surgical bays fought against the deep shadows where discarded prototype limbs and organ canisters gathered dust. The air today smelled of burnt copper and hot plasti-flesh.
Ripper himself was elbow-deep in the open thoracic cavity of a joy-toy whose gleaming internal chassis was exposed, wires spilling like neon guts. He didn’t look up as the door hissed shut behind Lucia. “Payment upfront,” he grunted, his hands steady as he soldered a connection with a pinpoint laser.
“I have credits,” Lucia said, her voice still rough from last night’s use. She enjoyed the rasp.
“From your alley venture?” Ripper’s tone was flat. He finished the join, the joy-toy’s legs giving a soft, mechanical shudder. He pulled his hands free, wiping them on a stained rag. His eyes, the color of old concrete, finally landed on her. They traveled from her buzzed hair, down over the geometric tattoos shifting restlessly on her skin, to the prominent cage and the glistening cybernetic sheen between her thighs. He didn’t flinch. He’d built most of it. “What now? Retro-reflective skin? Prehensile hair? I’ve got a client who wanted prehensile hair. Messy business.”
“I want to glow,” Lucia said, moving into the center light. She ran a hand over her breast. “The tattoos. I want them to pulse. To react.”
“Bio-luminescent subcutaneous ink. Standard.”
“When I come,” she clarified, her gaze holding his. “I want them to flare. A full-body light show.”
Ripper stared at her for a long moment. He tossed the rag aside. “Cocktail of neuro-transmitters linked to orgasmic climax triggers the ink’s photon emission. Could overload your pleasure centers. Fry you from the inside out with enough cumulative use.”
“Can you do it?”
“I can do anything with enough creds and a disregard for long-term viability.” He walked to a holo-terminal, pulling up her schematics. Her modified biology glowed in three-dimensional detail. “What else?”
“My tits,” she said, cupping them. “They’re good. But I want them… adaptable. Size-shifting. Tissue expansion subdermal nodes.”
He snorted. “Temporary, or permanent reset?”
“Temporary. For… effect.”
“Tasteless,” he muttered, entering the command. “But fine. Trigger? Manual, hormonal, neural?”
“All three.”
He shook his head, his jaw tight. “You’re a carnival act. What else?”
“My tongue.” She stuck it out. “I want it etched. Nano-filaments for enhanced sensation, texturing. Something… useful.”
“For deep-throating cyber-cocks without lube,” he finished, his voice devoid of inflection. “I have a diamond-weave pattern that’s popular with the pleasure-model androids.”
“That.”
“And?”
Lucia took a breath, feeling the buzz of anticipation mixed with something darker. She tapped her own nipples. “Piercings. Barbells. But with lactation ducts. Synthetic cocktail. Sweet. Addictive. Aphrodisiac qualities.”
Silence filled the clinic, broken only by the low hum of the machinery keeping the joy-toy alive on the table.
Ripper turned from the terminal. He looked old under the unforgiving lights, lines cut deep into his face. “You understand what you’re asking?” he said, his voice low. “The body has a finite capacity for rewiring. You’ve already replaced basic drives with engineered feedback loops. This… you’re moving beyond modification. You’re designing a toy. A single-purpose bio-mechanical toy.”
“I know my purpose,” Lucia shot back, a flicker of defiance cutting through her practiced submission.
“Do you?” He took a step closer. “Or is it just the only purpose anyone’s ever been willing to pay you for? You come in here with credits you earned on your back, on your knees, in some filthy alley, and you buy another piece of yourself to sell. Where does it end, Lucia? When you’re just a consciousness trapped in a chrome shell that does nothing but suck and fuck?”
His words were scalpel-sharp. They found seams in her she didn’t know were still there. She lifted her chin. “You did the cascade. You gave me the vault.”
“I did,” he conceded, the fight leaving his shoulders. “I was sober that day. Doesn’t make it right.” He ran a hand over his shaved head. “The ’scripts. You got a way to pay?”
She transferred the creds from her neural link. The terminal chimed.
Ripper stared at the confirmation. “Get on the table. The big one.”
The procedure was not like the back-alley quick-mod jobs. It was hours of precise, painful work. First, he injected the bio-luminescent catalysts around her existing tattoo lines, the needle a hot fire tracing her veins. Her skin burned. Then came the subdermal nodes for her breasts, inserted through tiny incisions beneath her armpits. He tested them; she watched in a mirrored panel as her DD cups swelled painfully to a massive G, then deflated again. She gasped.
“Neural link established,” Ripper muttered, his face illuminated by the holodisplay of her vitals. “Try it. Think ‘big’.”
Lucia focused. A warm, stretching sensation filled her chest, her breasts surging outward, heavy and full. “Good,” she breathed.
“Tasteless,” he repeated, but there was no heat in it now, just a dull professional fatigue.
The tongue modification was next. He clamped her mouth open, used a micro-laser to etch the diamond-weave pattern onto her taste buds and the underside of her tongue. The smell of cauterized flesh filled her nostrils. He applied a synthetic nerve-growth accelerator. It felt like her tongue was dipped in molten metal, then ice.
Lastly, the piercings. He used a local anesthetic on her nipples, but she felt the pressure as he punched the thick, hollow barbells through her flesh, the click as the clasps locked into place on the other side. He connected the thin, internal tubes to reservoirs implanted near her ribs, filled them with a milky, opalescent synthetic fluid.
“Test the system,” he said, handing her a small collection vial.
Lucia looked at the vial, then at him. She reached up, rolling one pierced nipple between her thumb and forefinger, activating the internal pump. A bead of pearly white liquid welled up at the tip of the barbell, then a thin stream arced into the vial. It smelled sweet, cloyingly so, with a hint of cinnamon and something chemical. Her own hormones spiked in response, a fresh wave of warmth pooling in her caged groin.
“It works,” she said, her voice husky.
“Of course it works.” Ripper powered down his tools. The heavy silence returned. “The tattoos will sync after your next orgasm. The connections need to be… cemented. A final calibration.” He looked at her, lying spread on his table, glistening with sweat and surgical gel, pierced, etched, and swollen. “You want to calibrate them now?”
She understood the offer. The sterile, impersonal test. She nodded, spreading her legs wider, presenting her permanently gaped entrance. “Calibrate me.”
Ripper didn’t speak. He walked to a cabinet, pulled out a chromed steel speculum. It was cold when he touched it to her. He clicked the mechanism, and the blades opened smoothly inside her, spreading her cybernetic vault wide. The internal walls, sleek and wet, were fully exposed under the bright lights. He attached a small sensor probe to the speculum, feeding data to his terminal.
“Manual stimulation,” he stated. “To achieve climax. It’s the only way to sync the bioluminescent triggers.”
Lucia reached down, her new tongue-in-protest aching in her mouth. She didn’t touch her caged cock—that was futile. She slid two, then three fingers into her wet, open channel alongside the cold steel. She thought of the barracks. Of Brack using her throat. Of Zoe’s promise. Of the line of mercenaries waiting tonight. She thought of the alley, and the faceless men, and the pure, empty utility of it.
Her breath hitched. Her back arched. The synthetic hormones in her system turbo-charged the climb. It was fast, brutal, and efficient. A sharp, shocking peak that ripped through her.
As the waves of her orgasm crested, the geometric tattoos across her abdomen, her thighs, her ribs, ignited. A soft, pulsating blue light emanated from beneath her skin, flowing along the intricate lines, throbbing in time with the contractions of her vault. The light show was beautiful, eerie, a map of her pleasure drawn in cold fire on her body.
Ripper watched the readouts, then the display on her skin. His expression was unreadable. “Synced,” he said flatly. He removed the speculum and the probe with a soft, metallic shuck.
Lucia lay panting, the light from her tattoos slowly fading to a faint, dormant glow. She felt utterly, perfectly modified. A toy calibrated for use.
Ripper cleaned his instruments. “You’re a walking biohazard,” he said, not looking at her. “And you’re running out of original parts to sell. Go on. Get out. Your… celebration awaits.”
Lucia slid off the table, her body singing with new potential. She gathered her clothes, not bothering to dress. She paused at the door, the sweet, addictive scent of her own lactating nipples filling the air between them.
“Thanks, Ripper,” she said.
He didn’t answer. He was already prepping for his next patient, his back to her, a solitary figure in the cold, glowing clinic.
She stepped out into the acid-drizzle twilight, her new tattoos shimmering faintly beneath the rain, her full breasts heavy, her tongue tracing the new ridges on her palate. The city’s neon reflected in the puddles, a promise of dark things to come. She walked towards the barracks, towards the waiting line, her body a testament to her purpose, ready to be fully, finally, used.
The barracks door slid open before she could input the code, yanked inward by a massive, scarred hand. Brack loomed in the entranceway, his photoreceptor eye flickering as it scanned her new, luminous tattoos and the absurd swell of her breasts. A slow, vulgar grin spread across his face.
“Look at the fuckin’ parade,” he called over his shoulder into the din behind him. He grabbed her arm, his grip tight enough to bruise unmodified flesh, and pulled her inside. “Ripper’s been busy. Got herself some party lights.”
The common area was thicker with mercs now, maybe a dozen, all in various states of undress and post-mission agitation. The air was a fog of synth-smoke, cheap alcohol, and aggressive testosterone. Conversations died as she was pulled into the center of the room. Eyes, hungry and evaluating, tracked the pulsing, faint blue glow beneath her skin and the heavy sway of her chest.
“Payment for the Kartell job,” Zoe’s voice cut through the chatter. She was leaning against a support beam, having shed her fatigues for just a tight black tank top and shorts. Her demeanor was different—sharper, edged with a victorious ferocity. The op had been a success. This was the reward. “You all earned it.”
A rough cheer went up. Glasses were raised. Lucia stood, naked under their collective gaze, her modified body thrumming with anticipation. This was not the alley’s anonymous transaction. This was claimed, communal. A belonging that was both terrifying and deeply validating.
Zoe pushed off the beam and walked toward her. The mercs parted. Up close, Lucia could see the fresh scuffs on Zoe’s armor stacked in the corner, the slight tremor of adrenaline still in her hands. Zoe cupped Lucia’s face, her thumb smearing the drizzle from her cheek. “Show them what you got.”
Lucia knew the drill. She turned, bent at the waist, and presented herself. She reached back with both hands, spreading her cheeks to offer a clear view of her glistening, cybernetic vault. A chorus of low whistles and murmured curses rippled through the room.
“She’s retooled,” Zoe announced, her voice carrying. “Deeper. No pain receptors. Just pleasure feedback. And a new throat.” She snapped her fingers. “Brack. Show them.”
Brack stepped forward, already hard. He didn’t bother with preamble. He fisted a hand in her hair and guided his thick cock to her lips. Her new tongue, textured with its diamond-weave etchings, slid out to greet him. He shoved in.
The seamless, deep-throat acceptance she’d demonstrated last night was now a public spectacle. She took him to the root in one smooth motion, her throat opening without a gag. The men watched, rapt, as her neck bulged with his shape. She bobbed expertly, the wet, slapping sounds loud in the sudden quiet. Her glowing tattoos began to brighten, a soft pulse matching her rhythm.
“Fuck me,” someone breathed.
Zoe watched, a possessive pride in her dark eyes. Then she unbuckled her own shorts. “Alright, you maggots. Form a line. One for the mouth, one for the ass. She can take it.” She pushed her shorts down her hips.
Lucia, her mouth full, her vision blurred with pleasurable tears, saw it. Zoe’s cock. It was different. Monumental. A throbbing, monstrous length of sleek black cybernetics and veined flesh, easily over sixteen inches long and thicker than a baseball bat. A recent, brutal upgrade, humming with suppressed energy.
Zoe saw her recognition, her wide eyes. A cruel, loving smile touched Zoe’s lips. “Surprise,” she mouthed.
Brack grunted, his hips stuttering, and came hard down her throat. She swallowed convulsively, the warm, salty spurts syncing with another wave of light across her skin. As he pulled out, gasping, another merc was already there, pushing Brack aside, shoving his cock into her waiting, dripping mouth.
At the same time, Zoe moved behind her. The cool, huge tip of her new cock nudged against Lucia’s exposed hole. There was no gradual penetration. Zoe gripped Lucia’s hips and drove forward with a single, powerful thrust.
The stretch was apocalyptic. Lucia screamed around the cock in her mouth, her body arching violently. Her vault, designed for size, was tested to its absolute limits. It burned, not with pain, but with an overwhelming, devastating fullness that scrambled her thoughts into pure static. Zoe bottomed out, her entire colossal length buried inside Lucia’s ass, their bodies slapping together.
“Holy shit, Zoe,” someone yelled.
“Like a fucking champ,” Zoe growled, and began to move.
What followed was a blur of sensation and light. Lucia became a conduit, a living port. Cocks slid in and out of her throat in a relentless, choking rhythm. Each time one finished, another took its place, feeding her a constant stream of come that she swallowed automatically. Her lactating nipples dripped their sweet, addictive fluid onto the floor.
And through it all, Zoe fucked her. Ruthlessly. Piston-like strokes that jarred Lucia’s entire skeleton, each thrust punching a choked scream from her lungs. The behemoth cock stretched her beyond what she thought possible, stimulating nerve clusters so deep inside her they triggered chain-reaction orgasms. Her body convulsed around the immense invasion, her glowing tattoos flashing like strobe lights, painting the barracks in pulses of electric blue.
“More!” Lucia rasped during a brief moment when her mouth was empty, spit and come drooling from her lips. “Fuck, please, more!”
They obliged. A merc knelt before her, guiding her lips to his cock while another fed his length into her from behind, double-penetrating her alongside Zoe’s monstrous girth. The pressure was astronomical, a summit of utter, brutal fulfillment. She came again, a shattering orgasm that made her tattoos blaze so brightly the room was cast in azure shadows.
One by one, the men finished. Some came in her mouth, some pulled out to spurt across her face, her breasts, her glowing skin. She lost count. Brack went twice. Through it all, Zoe kept fucking her, her cybernetic stamina inhuman, her massive cock never flagging. Lucia’s sounds became broken, continuous whimpers of overwhelming pleasure.
Finally, even Zoe’s breathing grew ragged. She slammed into Lucia one last time, her body locking, and a torrent of electric-hot synthetic come flooded Lucia’s depths, triggering a final, cataclysmic orgasm that left Lucia blind and trembling.
Zoe pulled out with a wet, sucking sound, leaving Lucia feeling cavernously empty. Lucia collapsed onto the cold, sticky floor, a twitching, luminous heap. Her body was a map of spent desire—bruises, bite marks, streaks of drying come, her own milky lactation smeared across her heaving chest. Her tattoos dimmed to a faint, residual glow.
The mercenaries, spent, patted her absently or chuckled as they dispersed to bunks or the showers. “Hell of a toy,” one muttered.
Zoe crouched beside her, running a surprisingly gentle hand through her sweaty hair. “You did good,” she whispered, her own exhaustion evident. “Perfect.”
But as the high receded, a strange, hollow need echoed in its place. The incredible stretching fullness was gone. The choking, swallowing rhythm had stopped. Her body, engineered for this, screamed for more. The cascade mods, the hormone regulators, they didn't understand “enough.” They only understood “more.”
Lucia pushed herself up on shaky arms. Her vault ached with a profound emptiness. Her mouth felt useless. Zoe and the others were leaving her, the celebration over.
“Wait,” Lucia croaked, her voice destroyed.
Zoe, heading towards her bunk, glanced back. “Sleep it off, Lu. You’re done.”
But she wasn’t. The fire was still there, banked but hot, an addiction with no off switch. She stumbled to her feet, ignoring the protests of her muscles. The barracks door hissed open for a merc heading out for a smoke. Without a word, Lucia followed him out into the neon-drenched night.
The cold air bit her sweat-slicked skin. The city hummed around her, a beast of endless desire. She wandered, her bare feet on the wet pavement, her glowing tattoos a beacon in the dark alleys. The emptiness inside her was a yawning chasm. She needed to fill it. She needed to be used.
She turned a corner, the sound of raucous laughter spilling from a dive bar. Inside, men would be drinking. Their eyes would find her. They would see her purpose.
Lucia walked towards the light.
