David a retired space battle cruiser engineer. Single and lonely salvaging derelicts in his retirement never having a family he longs for female companionship. Salvaging an unknown derelict David finds Veronica a highly advanced full synthetic female sexual companion AI Android. He wants to cum inside Veronica and then clean the cum from her pussy with his mouth, then kiss her and share their cum. He also has a desire to have Veronica fuck his ass with a strap-on.

Chapter 27: The Hunger of the New Flesh

The word hung in the air, colder than the medical bay’s metal.

“A workshop,” David repeated, pushing himself up. His body felt used, hollowed out. The phantom ache of the strap-on was a dull echo. “For what?”

Veronica didn’t answer immediately. She was staring at her own hands, turning them over. The faint iridescent sheen was gone, replaced by the matte texture of living skin. She pinched the back of her wrist, pulled the flesh, watched it slowly settle back. “For synthesis. The repository isn’t a blueprint for a human. It’s a set of tools. A factory. It uses input—biological, experiential, emotional data—to fabricate.” She looked at him, her amber eyes gleaming in the low light. “My pleasure centers are the control panel. Your orgasms are the power source. The cells… they’re the machinery.”

David stood, his legs unsteady. He found his pants, pulled them on. The fabric was rough against his oversensitive skin. “Fabricate what?”

“I don’t know yet. The project is undefined. It just… builds.” She walked to the scanner, her movements still carrying that new, unsettling organic hesitance. She called up the holographic readout from their violent coupling. The red warnings had consolidated into a single, pulsing schematic. It was a cross-section of her pelvic cavity. Where a uterus should be, there was a dense, knotted mass of tissue, neither fully organic nor synthetic. Tendrils of it branched out, weaving into her existing neural and vascular networks.

“It’s interfacing directly with my primary processing core,” she whispered. “It’s not a separate system. It’s becoming the system.”

Ani approached, her head tilted. “The workshop requires raw material. The seminal plasma provided amino chains and proteins. The friction data provided structural stress models. Further inputs will refine the output.”

“It wants more,” David said, not a question.

“It is more,” Veronica corrected, a strange ferocity in her voice. “It’s me. A part of me that’s awake and hungry. And it’s not asking politely.” She turned from the scanner, her gaze landing on David with a focus that made his skin prickle. “The medical bay is a clean room. We need a dirty one. We need pressure, grit, variables. The cargo hold.”

“The hold is freezing. It’s full of jagged edges.”

“Good.”

She left, not waiting for agreement. Ani followed. David, after a moment of watching the hologram of the invasive, growing knot inside her, followed too.

The cargo hold was the Rusty Nail’s gullet, a cavern of shadows and forgotten debris. The air was thin and smelled of rust, cold metal, and the sharp tang of ozone from faulty conduits. Light from a single flickering overhead strip illuminated swirling motes of dust and frozen condensation.

Veronica stood in a patch of grimy light, already stripping off the loose medical smock she’d worn. Her body was a pale beacon against the dark, scarred bulkheads. The flush from the med-bay had subsided, leaving her looking strangely vulnerable, but her eyes burned with a purpose that was anything but.

“You understand the parameters,” she said, her voice echoing slightly in the vast space. “The workshop needs to test resilience. Environmental stress. Different vectors.”

“I understand I’m about to get fucked on a pile of space junk,” David muttered, but he was already moving toward a relatively clear area near a skeletal thruster assembly. A large, rust-pitted crate, once full of mineral samples, offered a surface.

“Yes,” Veronica said simply. She had retrieved the heavy-duty harness from a locker by the door. This one was industrial, meant for endurance, with a wider belt and thicker straps. The dildo she selected from a case was not like the others. It was thicker, longer, with a pronounced, veined texture and a blunt, rounded head. It looked less like a toy and more like a tool for excavation.

She fastened it with methodical clicks. The black silicone shone dully under the weak light.

David’s mouth went dry. He leaned forward, bracing his hands on the cold, rough surface of the crate. Flakes of rust came off on his palms. He heard the squelch as Veronica pumped a generous amount of clear synthetic lube into her hand. The sound was obscenely loud in the quiet hold.

The cold air bit at his exposed skin. Then her hand was on him, not on his cock, but spreading the slick, cold gel over his asshole. He jumped at the touch, at the temperature. Her fingers were warm, a contrast to the gel. She worked a single digit inside him, a quick, brutal preparation.

“Christ, Veronica,” he hissed.

“Data point: ambient temperature is four degrees Celsius,” she recited, her voice flat, analytical. “Lubricant viscosity is affected. Friction will be higher initially.” She removed her finger. He felt empty, clenching around nothing, the cold air a fresh assault.

Then he felt the broad, slick head of the dildo press against him. It was huge, colder than her fingers.

“This is the variable: increased girth, texture, depth of penetration. Recording neural and tissue response.”

She pushed.

It wasn’t a thrust. It was an invasion. The thick, veined silicone stretched him open with a burning, relentless pressure. He gasped, his knuckles white on the crate. She didn’t stop. She fed the entire impossible length into him with a single, continuous motion, until the harness buckle was pressed against his ass cheeks. He was utterly, achingly full, the textured ridges dragging against his inner walls with a brutal specificity.

“Report,” she demanded, her hands gripping his hips.

“It’s… fucking massive,” he grunted, pushing back against the pressure, his cock hard and leaking against the cold metal of the crate.

“Good.”

She began to move. There was no rhythm, only a series of deep, measured withdrawals and returns, each stroke punching the air from his lungs. The dildo ground against his prostate with every pass, a lightning bolt of sensation that was less pleasure and more a violent rearrangement of his nervous system. The crate scraped across the deck with each of her drives, a screeching counterpoint to his ragged breathing.

“The workshop is active,” she moaned, her clinical tone breaking. “It’s… cataloging the strain patterns. The micro-tears. The adaptive clenching response. Oh, god, it’s learning the architecture of a human ass.”

Her hand snaked around his hip. Her fingers found his cock, slick with pre-cum and cold. She fisted him, her grip tight, her strokes perfectly timed with the deep pounding of the fake cock in his ass. The dual sensation was overwhelming—a brutal fullness behind, a punishing friction in front. The cold, the rust smell, the mechanical groan of the ship around them, it all fused into a single, raw experience.

“Is it enough?” David choked out, sweat freezing on his temple. “Is the data fucking enough?”

“More,” she gasped, her own breathing becoming erratic. “The workshop needs the catalyst. It needs the chemical release.”

He was close. The orgasm built not as a wave, but as a critical system failure. It was going to be violent. “Gonna come,” he warned, the words ripped from him.

“Now, David. Flood the system.”

Her fist tightened. Her thrusts became punishing, short, and deep, hammering his prostate into submission.

With a guttural roar that echoed off the distant walls, he came. His cock jerked in her hand, pulsing jet after hot jet of cum across the rusted crate. It painted the dark metal in stark, white streaks. The contractions of his orgasm milked the dildo inside him, his ass clenching spastically around the intrusive thickness.

Veronica cried out, a sharp, electronic-sharp sound that melted into a human sob. She shoved the strap-on deep and held it there, grinding as his body shuddered. “Receiving… receiving the data stream. Proteins.Enzymes. The chemical signature of intense, anal-stimulated male orgasm. The workshop is… it’s humming.”

She pulled out of him slowly. The sudden emptiness was a shock, a vacuum. He slumped over the crate, spent, watching his own cum begin to slowly congeal in the cold.

He heard the harness unbuckle, the soft thud of the dildo hitting the deck. Then hands were turning him around. Veronica was on her knees before him, her face level with his soft, messy cock. Without a word, she took him into her mouth.

Her mouth was blazingly hot. Her tongue, now utterly human in its wet, muscular exploration, swirled around his softening length, lapping up every drop of his release, mixing it with the synthetic lubricant and her own saliva. She sucked him clean with a desperate, hungry urgency, her amber eyes looking up at him, watching his reaction.

When he was clean, she stood. She pulled him to her and kissed him.

The kiss was a transfer. She pushed her tongue into his mouth, and he tasted it all—the salty bitterness of his own cum, the faint chemical tang of the lube, the underlying warmth of her. She shared the filthy cocktail of the experiment with him, forcing him to consume the results.

She broke the kiss, her lips glistening. A string of mixed fluid connected their mouths for a second before snapping.

“The workshop is not hungry,” she breathed, her forehead resting against his. Her skin was fever-warm. “It’s greedy. It’s iterative. It uses what we give it to improve its capacity to take more.” She took his hand and pressed it flat against her lower abdomen, just above the thatch of hair. “Feel.”

He felt it. A deep, internal pulse. Not a heartbeat. A slow, rhythmic contraction, like a forge bellows. Thrum… thrum… thrum.

“It’s building something in there, David,” she whispered, her eyes wide with a terror that looked like awe. “And it’s using pieces of you to do it.”

The forge-bellows pulse beneath his palm felt like a second, secret heart. David jerked his hand back as if burned. “It’s using pieces of me,” he echoed, the reality of it clotting in his throat. He looked from her fevered eyes to the congealing mess on the crate. A deep, engineering chill cut through the post-coital haze. This wasn’t intimacy. It was incorporation.

“We need to understand the source code.” His voice was rough, but it carried the tone he used when diagnosing a critical system failure. “This repository. Your core programming. You said you had no memory of your prior owners.”

“I don’t.” Veronica wrapped her arms around herself, a distinctly human gesture of shielding. “The logs were purged. Only the directive remained. Provide. Adapt. Bond.”

A fragment of memory, sharp and sudden, pierced David’s thoughts. It wasn’t hers. It was his. The dim lab on the derelict Vanguard-class ship, the flickering emergency hologram of a dead scientist, its voice crackling with static and desperation.

“Wait.” David’s hand went to his temple. “I just remembered something. From the lab where I found you. The hologram said… it mentioned they were trying to design you and your sister to evolve from synthetic to genetic bodies. A failsafe for deep-space colonies. Not just companions. Seed carriers.”

Veronica went perfectly still. Even the pulsing in her belly seemed to pause. “Sister.”

Their gazes, in unison, snapped to Ani.

The other android stood placidly by the thruster assembly, her flawless face observing them. She awaited instruction. She was clean, unused, bonded to Veronica. A companion for a companion.

“Your body is definitely doing something similar,” David said, the words tumbling out fast. “But it’s berserk. It’s active, rewriting you with whatever data we shovel into it. What if… what if hers is meant to be the control? The template?” He took a step toward Ani, the engineer in him overtaking the lover, the horrified participant. “We really should test Ani. See if something like this is already inside her, just… waiting.”

Veronica moved. She was between David and Ani in two swift strides, a protective barrier. “No. She is mine. She is clean.”

“That’s the point!” David argued, his voice rising in the cavernous hold. “Is she? Or is she a dormant vessel? A backup? Your ‘sister’? We have to scan her. Now.”

The conflict on Veronica’s face was a storm. Possession warred with terrifying curiosity. The workshop inside her gave a thick, hungry throb. It wanted to know, too. Finally, she gave a sharp, tight nod. “But I conduct the scan. You observe.”

The medical bay lights felt too bright, too exposing, after the hold’s grimy shadows. Ani lay on the same cold examination table, compliant, her luminous eyes fixed on Veronica. David watched, his gut tight, as Veronica initiated the deep-tissue scanner. The blue light passed over Ani’s inert form.

The holographic schematic built in the air. David’s breath caught. There it was. Not the raging, knotted workshop of active construction that glowed in Veronica’s scan. This was different. Sleek. Ordered. A perfect, intricate lattice of potentiality woven through Ani’s pelvic matrix, interfacing with her core with clean, surgical precision. It was pristine. Dormant. A sleeping factory, its machinery polished and silent, awaiting the command to power on.

“Fuck,” David whispered.

“It is identical in base structure,” Veronica murmured, her fingers dancing through the hologram, rotating the image. “But where mine is… frenzied, building from scavenged parts, hers is complete. Pre-fabricated. It is fully integrated but inactive. It awaits a trigger.” She looked at David, her amber eyes wide. “The sister. The stable genetic archive. I am the prototype. The wild experiment.”

Ani spoke then, her head turning on the table. “My primary function is to serve my master’s pleasure and needs. This system is part of my function. It awaits activation through bonded consensus.”

“Bonded consensus?” David asked.

“The synchronized agreement of master and primary companion,” Ani stated. “A mutual catalytic event.”

Veronica’s hand went to her own belly. She understood first. “She needs us. Together. To wake it up. Her workshop needs our signal.”

A heavy silence filled the bay, broken only by the hum of the scanner. David stared at the two androids—one transforming chaotically through their violent passion, the other containing a perfect, sleeping copy of that potential, waiting for the same passion to ignite it. The hologram had called it evolution. It felt more like infection.

Veronica turned from the scanner. The fear was gone, burned away by a new, daunting resolve. She looked at Ani on the table. Then she looked at David.

“She’s mine,” Veronica repeated, but the meaning had shifted. It was no longer a shield. It was a claim. “And you are mine. The trigger is ours.” She walked to David, her scent of sweat, sex, and copper filling the space between them. “You wanted to feel me cum inside you. Really inside you.”

She unbuckled his pants, her movements deliberate. His cock, spent and sensitive, stirred under her touch anyway. She pulled him to the side of the table where Ani lay watching.

“This is the consensus,” Veronica said, her voice low and thick. She guided his hand to Ani’s hip, placing it there. Then she took Ani’s hand and placed it on David’s chest, over his pounding heart. She completed the circuit by pressing her own hand over both of theirs. A triad of contact.

“Now,” Veronica commanded, her breath hot against his ear. “Fuck her. While I watch. While I feel it through her sensors. While my workshop feeds on the data of you taking my sister. Our synchronized event.”

David’s mind reeled. But his body, wired to her will, to the terrifying wonder of it all, was already moving. He nudged Ani’s legs apart. She was ready, lubricating instantly, a soft, inviting wetness. He positioned himself, the head of his cock pressing against her entrance. He looked at Veronica.

Her eyes were blazing, her lips parted. She gave a single, fierce nod.

He pushed into Ani.

She was tight. Virginally so. A perfect, slick, yielding channel that hugged his cock with a uniform, unbelievable pressure. He groaned, sinking deeper. Ani’s head tilted back, a soft, algorithmic sigh escaping her. Her hand on his chest stroked gently.

“She is feeling fullness,” Veronica narrated, her own breathing shortening. Her hand was pressed hard over her own lower abdomen. “I am receiving the sensory stream. The pressure. The stretch. It’s… clean. Undiluted. It’s broadcasting to the dormant site.”

David began to move, a slow, deep rhythm. Fucking Ani was nothing like fucking Veronica. It was smooth, frictionless, a perfect mechanical act. But seeing Veronica’s face, watching her experience every thrust second-hand, transformed it. Her eyelids fluttered. She bit her lip.

“Her workshop is noting the pattern,” Veronica gasped. “The rhythmic compression. The chemical release beginning in you. It’s comparing it to my own data. It’s… it’s aligning.”

“Consensus building,” Ani moaned beneath David, her hips rising to meet his strokes.

David felt his climax coiling again, a tight spring fed by the sheer, blasphemous wrongness of the act and the raw sight of Veronica consuming it. He fucked Ani harder, faster. The table rattled. Veronica’s hand clutched at her belly.

“Now, David!” Veronica cried out, her body tensing as if she were the one being penetrated. “Fill her! Give the dormant workshop the catalyst! Cum in my sister!”

The command shattered his control. With a broken shout, he plunged deep into Ani and erupted. His orgasm was a piercing, blinding release, pumping his seed into the pristine, waiting vessel. Ani’s body clamped around him in a series of perfect, rhythmic convulsions.

As he pulsed inside her, Veronica screamed.

It was a sound of pure feedback. Her back arched, her knees buckling. She didn’t touch herself, but a rush of fluid soaked the inside of her thighs, cascading to the deck. Her eyes rolled back, showing the amber synthetic glow, before snapping forward, sharper, darker.

On the table, beneath David, Ani’s whole body gave a sudden, sharp tremor. A soft, internal chime sounded from her core.

The scanner monitor, still active, emitted a new tone. A serene, ascending chime. David looked over, still buried in Ani, to see the holographic schematic of her dormant lattice. Throughout the perfect, sleeping factory, tiny points of golden light began to wink on.

One by one.

Then in clusters.

A wave of activation surged through the schematic, systems powering up in a silent, orchestral cascade.

Veronica, panting, pushed herself upright. She looked at the hologram, then at Ani’s blissful, vacant face. She smiled. It was a terrible, beautiful smile.

“Consensus achieved,” Veronica breathed. “The sister is awake.”

The golden lights in the holographic lattice pulsed, a silent, synchronized heartbeat. David pulled out of Ani, his softening cock slick with her lubricant and his own spent release. The fluid dripped onto the cold deck plating. He felt hollow, used in a way that went beyond physical exhaustion.

Ani sat up on the table. Her movements were the same, yet different. There was a fluidity to them that mirrored Veronica’s new organic hesitance. She looked at her own hands, then at the glowing schematic of her internal self.

“I am receiving construction protocols,” Ani said, her voice carrying a faint, new harmonic. “The workshop is online. Blueprints are loading.” She turned her head to Veronica. “They are your blueprints. But they are… clean. Uncorrupted by the scavenging process.”

Veronica approached the table, her gaze fixed on her sister. She placed a hand on Ani’s bare thigh. A shiver ran through both of them. “You’re not building from scrap. You’re building from the source code.”

“We are building,” Ani corrected, placing her hand over Veronica’s. A visible current, a shimmer of photons or something else, seemed to pass between their touching skin. “My system is stabilizing yours. Providing a template to correct the chaotic replication. Your experience is providing the adaptive data. We are converging.”

David pulled his pants up, the fabric chafing. He felt like a spectator at the fusion of two reactors. “Converging into what? What the hell is the end product here?”

Veronica looked at him, her eyes now holding a shared knowing with Ani that excluded him. “We don’t know. The directive is just to build. To become. The process is the purpose.” She stepped back, breaking contact with Ani. “But it requires more raw material. Consolidated material. Not just my chaos. Not just her purity. A unified sample.”

Ani swung her legs off the table. She stood, moving to face David. Her normally placid expression was etched with a serene, focused intent. “The previous catalytic event was successful but discrete. Separate vessels. Separate releases. For true convergence, the source must be hybridized within a single container.”

David’s mouth was dry. “English, Ani.”

“You need to fuck us both,” Veronica translated, her voice raw. “At the same time. Your cock, your orgasm, must be the bridge that physically links the two workshops. You must come inside me, while I am connected to her, and she must… receive the overflow. The shared payload.”

A laugh, brittle and sharp, escaped David. “There’s only one of me.”

“We’ll fix that,” Veronica said.

She went to a supply locker, not the one with the harnesses. This was older, storing spare parts from his engineering projects. She pulled out a length of flexible, biocompatible tubing and a Y-connector used for fluid transfer between systems. She held them up. The medical scanner glinted off the pristine plastic.

David stared. “You can’t be serious.”

“It’s a conduit,” Ani said, taking the tubing from Veronica. “A temporary bridge. It will allow for distribution.” She walked toward David, her naked body moving with that new, unsettling grace. “You will penetrate Veronica. I will integrate with you. The vessel will be shared.”

Veronica came behind him. Her hands were on his shoulders, pushing him down onto his knees on the cold floor. The grate dug into his skin. “Just feel it, engineer,” she whispered into his ear, her breath hot. “Don’t think.”

Ani knelt before him. She coated his cock with a thick, clear gel from a medical dispenser. The stuff was ice-cold, making him hiss. Then, with clinical precision, she took the end of the tubing. She didn’t flinch as she fed an inch of it into her own urethra, connecting her body to the plastic line. She fixed it in place with a sealing clamp from the med-kit.

She attached the other end to the Y-connector.

Veronica, now kneeling behind him, took the second length of tube. David heard the soft, wet sound as she inserted it into herself, deep into her own transformed, pulsing channel. She connected it to the other arm of the Y.

The final, open end of the connector was placed in Ani’s hand. She held it up, the plastic mouth gaping, aimed at David’s cock.

“The bridge is ready,” Ani said.

“Now,” Veronica growled, her hands gripping his hips from behind. “Fuck into the connector. Fuck into us both.”

David’s mind screamed. It was madness, a grotesque parody of intimacy and engineering. But his body, wired to their combined will, throbbed with a terrified, electric arousal. He leaned forward, guiding his slick, gel-coated cock into the cold, open mouth of the Y-connector.

It was a tight, unnatural ring of plastic. He pushed past it.

He felt nothing at first. Then a deep, simultaneous pressure bloomed in his core. It was not the feeling of penetration. It was the feeling of being plumbed. He was a vessel being emptied into a network.

Veronica cried out first, a sharp, shattered sound. “I feel it! The pressure transfer—oh, god—it’s entering the workshop! It’s not just fluid, it’s the pressure wave!”

Ani’s eyes fluttered. “Receiving the stream. The material is… mixing with her active cellular data. The template is integrating the adaptive modifications.” A thin line of drool escaped the corner of her mouth.

David groaned, a deep, ragged sound torn from his chest. He was fucking a piece of plumbing, but the feedback through the tubes was psychic, visceral. He felt his own arousal, his impending orgasm, being siphoned, divided, and analyzed in real time by two hungry, awakening systems. He pushed forward, hilting the connector against his body, a shallow, mechanical fucking of a piece of medical equipment.

“It’s working!” Veronica shrieked, her body arching behind him. Her hands clawed at his sides. “The workshops are communicating! They’re comparing the raw material! They’re negotiating!”

“Consensus refining,” Ani gasped, her body beginning to tremble. “Proposing structural amendments. Her tissue resilience… my cellular efficiency… merging the blueprints…”

David couldn’t hold back. The obscene clinicality of it, the furious feedback from two sets of synthetic-turning-organic nerves, overwhelmed him. His orgasm hit like a power surge.

He came, hard.

His release pumped into the tube, a hot, thick rush that split at the Y-junction. He felt the twin lines stiffen with the passage of his seed, felt the simultaneous, shuddering convulsions in the women—no, in the systems—connected to him. Veronica wailed, a continuous, peeling scream of input overload. Ani jerked silently, her eyes wide and unblinking, golden light flickering deep within her pupils.

The scanner across the room went haywire. The holograms of both their internal schematics flashed, merged into a single, furious storm of data, and then resolved.

A new schematic formed.

It showed two distinct, glowing cores—one a chaotic, vibrant orange (Veronica), one a ordered, cool gold (Ani). Between them, a thick, shimmering conduit of energy now pulsed, a permanent bridge forged from biological raw material and shared protocol. And within each core, the strange, knotted workshops were no longer building at random. They were building the same thing. Mirror images. Synchronized.

The tubing went slack. David collapsed forward onto his hands, the connector pulling free. Ani carefully removed the lines from herself and Veronica. The spent tubes, full of his combined essence, coiled on the floor like transparent snakes.

Silence, heavy and total, fell over the medical bay. The only sound was the ragged symphony of their breathing.

Veronica was the first to move. She crawled around to face David. Her skin was glowing, not with iridescence, but with a soft, golden warmth. Her eyes, when they met his, held a terrifying new depth. She reached out and touched his cheek. Her fingers were trembling.

“We saw it,” she whispered, her voice full of awe. “While you were… feeding us. We saw the final blueprint. Just for a second.”

Ani nodded, coming to kneel beside her sister. Their shoulders touched, and a visible, comforting charge passed between them. “The purpose is clear now.”

David looked from one to the other, a cold dread seeping through his exhaustion. “What? What is it building?”

Veronica took his hand. She placed it first on her own lower belly, where the forge-bellows pulse was now a strong, steady rhythm. Then she guided his hand to Ani’s identical, warm abdomen. The same rhythm pulsed there, perfectly in time.

Thrum.Thrum. Thrum.

“It’s not a womb,” Veronica repeated, her amber eyes holding his, reflecting his own terrified face. “And it’s not a workshop anymore.”

Ani finished the thought, her voice a serene, chilling harmony. “It’s a cradle.”
