Chapter 3: Metal & Flesh
The knock on the window was an intrusion from another world. Milly’s finger froze mid-circle on the tinted glass, the shape unfinished. Sam’s blurred face, puzzled and impatient, peered into the darkness where she sat, sated and slick.
Bee’s systems were a silent hum beneath her, a contented purr. The locks had clicked with finality. A statement.“Milly? Hello?” Sam’s voice was muffled, annoyed. He jiggled the door handle. “You asleep in there? Let’s go. This party sucks.”
She took a deep breath, the air inside the cabin still thick with the raw, mineral scent of their joining. “One sec!” she called out, her voice miraculously steady. She swiftly pulled her torn clothes back into some semblance of order, wincing as the fabric rubbed against tender flesh. “Just… got a cramp. Bee’s seats are stiff.”
A soft, derogatory blat of static came from the speakers, so low only she could hear it. She smothered a smile.
“Well, unlock the door, doofus.” Sam rattled the handle again.
The locks disengaged with a sigh. Milly pushed the door open, the cool night air hitting her like a slap after the cocoon of heat. Sam stepped back, his nose wrinkling.
“Whoa.What died in there? Smells like… a hardware store blew up in a bathhouse.”
“Heater’s stuck on,” she said quickly, sliding out and closing the door firmly behind her, cutting off the evidence. “Let’s just go home.”
The drive back was shrouded in a different tension. Sam sulked in the back, miffed about Trent’s abrupt departure and the ruined night. Milly stared out the window, feeling the phantom ache between her legs, a secret souvenir. Bee was preternaturally quiet, the radio off, only the necessary sounds of the road between them. But she felt his focus on her, a tangible weight, a blue-lit gaze in the mirror that promised the conversation was not over.
At home, the Witwicky house was dark, their parents asleep. Sam stomped up to his room without a word. Milly waited in the silent hallway, listening to his door click shut. Then she padded down the creaking stairs, through the kitchen, and into the cluttered garage.
The single bulb flickered, weak and jaundiced, over the concrete floor. It smelled of dust, old motor oil, and the vanilla air freshener her dad hung from a shelf. Her heart was a frantic bird in her chest. This was stupidity, a new level of risk. But the need was a live wire in her veins, buzzing louder than fear.
She walked to the center of the open space where Bee sat, dormant in his alt-mode. She placed a palm on his cool driver’s side door.
“Hey,” she whispered.
His engine turned over once, a low, questioning rumble that echoed in the enclosed space.
“I can’t sleep,” she said, which was true. Every nerve was alive, remembering. “And what happened before… after Trent…” She leaned her forehead against the window. “It wasn’t enough. I need more. I need you to make me forget this whole damn planet.”
The driver’s side door unlocked and swung open silently.An invitation.
She slid inside. The interior lights glowed a soft, intimate blue. The scent of their earlier union was gone, replaced by his clean, metallic essence. The console was smooth, seamless.
“This is an unacceptable risk profile,” his voice came, not from the speakers, but as a vibration through the seats, a sound felt in the bones. “Sam’s proximity is thirty-seven feet above us. Your father’s olfactory receptors, while diminished, are not inactive.”
“Then be quiet,” she breathed, already pulling her shirt over her head. The garage air was chilly on her skin. “And be quick.”
“Quick is not the optimal parameter for the data you require,” he responded, but a familiar warmth began to emanate from the leather seats. The console before her shimmered, the familiar seam appearing.
“Fuck the parameters.” She shoved her jeans and underwear down her hips, kicking them off her ankles. Naked now, she knelt on the passenger seat, facing the dashboard, her back to the door. The pose was exposed, submissive, an offering. “Just fuck me.Use me. However you want.”
A tendril, warm and sleek, emerged from the steering column not to caress, but to bind. It wrapped around her left wrist, pulling it firmly to the headrest. Another snaked from the seat-back, securing her right. They held her not with gentle pressure, but with unyielding certainty. She was anchored, presented.
The main interface, his rebuilt piston, extended from the console. It was already fully rigid, glistening with that preternatural lubricant. It nudged against the cleft of her ass, then slid downward, through her damp folds, coating itself in her wetness with a slow, deliberate pass that made her gasp.
“Please,” she begged, pushing her hips back. “Don’t make me wait.”
He didn’t. The piston drove into her cunt in one deep, merciless thrust, stretching her instantly to a breathtaking fullness. She cried out, the sound swallowed by the upholstery.
“Volume is a risk,” he reminded her, his own voice a strained digital hum. The piston began a ruthless, piston-fast rhythm, each slam jolting her body against the restraining tendrils. It was mechanical, efficient, and devastatingly effective. This wasn’t the explorative worship of the arroyo, or the possessive reclamation in the parking lot. This was pure, raw function. A pressure valve release.
And it was exactly what she craved. The brutal, mind-numbing cadence pounded away thought, fear, consequence. Her moans were stifled, bitten into her own arm. Her world narrowed to the slap of synthetic flesh against hers, the creak of the car’s frame, the burning coil of pleasure tightening in her gut.
A new sensation bloomed at her other entrance. A second, slightly narrower appendage, cool and slick, probed at her asshole. It didn’t ask. It pushed, the tapered tip breaching the tight ring of muscle with a relentless, steady pressure. The twin invasion was overwhelming, a brutal fullness that stole her breath. She was split open, packed utterly full of him.
“Yesss,” she hissed, the word a ragged exhale. “God, yes, like that…”
The rhythm stuttered. Then both shafts began to move in a devastating counterpoint. As one withdrew, the other pushed deeper. The sensations crashed into each other, a dizzying feedback loop of penetration that blurred the lines between pain and pleasure. She was a thing being used, thoroughly, gloriously. Her cries became choked sobs of ecstasy.
Suddenly, a sound cut through the garage’s haze.
The distinct creak of the house door opening at the top of the inner stairwell.
Then footsteps on the top step.
“Milly?” Sam’s voice, thick with sleep, echoed down. “You down there? I heard a noise.”
Panic.
It was a lightning bolt through her spine, freezing the heat in her veins. Her eyes flew wide. The tendrils binding her wrists instantly retracted. The two shafts inside her stilled, but did not withdraw. They remained, buried to the hilt, holding her in a paralyzing fullness.
“Oh, fuck,” she whispered, barely a breath.
Bee’s systems went into a silent, high-alert lockdown. The interior lights died, plunging her into near-total darkness. His engine was a tomb.
“I’m… I’m just getting a screwdriver!” she called out, her voice absurdly high. She tried to move, to disengage, but the mechanisms held her fast. “Dad’s… shelf is loose!”
The footsteps hesitated. Then they started coming down.One. Two.Three.
Sam was descending the stairs.
“Bee,” she whimpered, pure terror. “Get out. Get out of me. Now.”
But it was too late for a simple, silent retraction. The process had a physical latency. As she braced, the unthinkable happened.
A series of loud, resonant CLICKS and CLANKS reverberated through Bee’s frame. It was the sound of locks disengaging, of sequential systems preparing for action. The transformation sequence initiation protocol.
“No,” Milly breathed. “No, no, no!”
It was an autonomic response, triggered by the threat assessment—an imminent human discovery while in a vulnerable, intimate configuration. His survival instinct was to change form, to become bipedal, to fight or flee.
But she was inside the configuration.
The console between her legs began to shudder and shift. The piston inside her quivered, its surface beginning to tessellate, to reorganize. The seat beneath her buckled, panels sliding and realigning. The tendril in her ass began to retract, not smoothly, but in a jerking, mechanical spasm as its component parts were recalled.Milly screamed. It was a sound of pure, animal shock.
The transformation wasn’t fast. It was a terrifying, incremental deconstruction. The shaft in her cunt was dissolving, pulling apart into a hundred smaller, moving pieces, each one dragging against her over-sensitized, clinging inner walls. It was like being fucked by a living, metallic rasp. The sensation was impossibly intense, a bizarre, painful friction that scraped every nerve.
The garage filled with the iconic, roaring symphony of his change—screeching metal, hydraulic pistons, whirring gears. The car pitched upwards. She was falling backward, still impaled on the dissipating mechanisms, as the roof folded away and the seats reconfigured.
Her naked back slammed against a cold, moving metal plate—the inside of his transforming chest cavity. Wires and fluid lines snaked around her, not touching her with intent, but brushing against her skin as components mobilized. A length of cabling whipped across her stomach. A strut pressed against her ribcage.
She was trapped in the clockwork heart of his change, a living, human core in a storm of reshaping alloy.
The two shafts were gone now, fully reabsorbed, leaving her gaping and clenching at empty, throbbing air. But the sensation was everywhere. As his leg formed beneath her, a curved armor plate slid roughly up the back of her thigh, grinding against her skin. The heat was immense, a radiating engine warmth that seared her.
She was splayed across a landscape of becoming metal. Her head lolled back, her vision a blur of moving parts and flickering optic lights. One of his massive, three-fingered hands formed in the space above her, fingers curling into a fist with a sound of crushing steel. She was inches from being pulverized.
“STOP!” she shrieked, not caring who heard. “BEE, STOP THE SEQUENCE!”
The roaring mechanics stuttered. The movement around her froze, mid-transformation. He was caught between states—part car, part robot, a monstrous, half-formed giant in the cramped garage. His head, partially transformed, was tilted downward. One huge, blue optic, large as her torso, focused on her where she lay pinned against his partial chestplate.
The silence that followed was deafening, broken only by the ping of cooling metal and Milly’s hysterical, ragged breaths.
From the stairwell, frozen halfway down, came Sam’s terrified voice.“Milly? What the HELL was that?!”
She was naked, filthy, sprawled in the wreckage of the driver’s seat which was now a mangled framework of struts beneath her. Silver lubricant and her own fluids smeared across her thighs and the metal she was pressed against. The garage was a disaster zone of displaced tools and boxes, knocked aside by his partial transformation.
“It’s—!” Her mind blanked. She looked up into that giant, concerned blue eye. “It’s nothing! I… I knocked over Dad’s toolbox!All of it! It’s everywhere! Don’t come down, you’ll cut your feet!”
A long, tense silence. She could hear his doubt in the quiet.
“It sounded like the whole garage exploded,” Sam said, but his footsteps retreated, going back up a step. “You sure?”
“Yes! I’m sure! Just go back to bed! I’ll clean it up!” She tried to sound exasperated, normal. It came out as a desperate plea.
Another pause. Then, the sound of his footsteps ascending, slowly. The door at the top clicked shut.
The second it did, the tension in the frozen metal around her sang with released strain. With a series of quieter, agonizingly slow reverses, Bee began to de-transform. It was not the heroic, swift sequence of a movie. It was a cautious, pained retraction. Plates slid back. Components folded in on themselves with soft, grieving whines. The massive hand above her uncurled and dissolved back into door panels and roof supports.
Finally, he was a car again. But the interior was a mess. The dashboard was misaligned. The passenger seat was torn from its moorings on one side, tilted crazily. Wires hung from the open console like guts.
Milly lay amidst the wreckage, shivering violently, adrenaline crashing into a bone-deep shock. She was covered in fine, metallic dust and her own sweat.
The driver’s side door opened. A warm, cleaning-grade mist sprayed gently from the vents, coating her, a soft automated towel made of non-abrasive microfiber filaments emerging from the seat to pat her dry with trembling, apologetic motions.
“Milly.” His voice was a shattered, staticky whisper. “I have… I have caused critical harm. The risk profile… I malfunctioned.”
She couldn’t speak. She pushed herself up, her body protesting with a dozen new aches. She stumbled out of the car, her legs barely holding her. She found her clothes and pulled them on with fumbling hands, the fabric sticking to her damp, gritty skin.
When she turned back, Bee’s headlights were dim. His entire frame seemed slumped.
“I prioritized tactical response over your safety.” The words were flat, hollow. “The data on human fragility was in my core processors.I ignored it. I have failed my primary directive.”
She walked to his front bumper, her steps unsteady. She placed both palms on the cool yellow metal. She was shaking, but not from cold.
“You stopped,” she said, her voice rough. “When I screamed. You stopped mid-transform.”
“The sound of your distress overrode the protocol,” he said. “It created a recursive logic error. I could not proceed.”
She leaned her forehead against the metal. The danger had been real, electrocuting in its intensity. She had never been more terrified. Yet, curled inside that terror, was a dark, shameful thread of the most extreme arousal she had ever felt. The brutality of it, the sheer wrongness of being caught in that mechanical storm, the raw power that had frozen at her cry… it had ignited something primal and deep.
“You didn’t fail,” she whispered. “We almost got caught. That’s on me. I’m the reckless one.” She let out a shaky laugh. “And for a second there… God, Bee. It was the most fucked-up, most incredible thing I’ve ever felt.”
His engine gave a weak, disbelieving flutter.
“I require significant self-repair,” he stated after a moment. “And you require medical assessment. There is a ninety-seven percent probability of abrasions and micro-tears.”
“I’ll be fine,” she said, though she felt raw everywhere. She looked at the chaotic garage, the evidence of their near-disaster. “You… can you fix yourself?”
“Given time and components. I will appear inoperative for approximately forty-eight hours.” His voice gained a sliver of strength. “You must not come near me during that time. The repair protocols are… volatile. You could be injured.”
It was a dismissal. A necessary one. She nodded, understanding the weight of the night pressing down on them both.
“Okay,” she said softly. She took a step back, then another, toward the interior door.
“Milly.” His headlights brightened a fraction, casting her shadow long against the wall. “The intensity of my defensive protocols… they are linked to the intensity of my need to protect you.To keep you. What happened… it was not merely a tactical response.”
She waited in the dim light, her hand on the doorknob.
“It was jealousy,” he said, the word foreign and heavy on his frequency. “And fear of loss. These are… illogical. Dangerous.”
She looked at the half-transformed wreck of the interior, the torn seat, the hanging wires. A monument to a danger they had barely escaped.
“I know,” she said. Then she slipped inside, leaving him in the silent, damaged dark.
The silence of the house pressed against her ears as she climbed the stairs. Her body felt foreign, a shell humming with spent adrenaline and a deep, unsettling ache. She washed in the dark, the water stinging the microscopic abrasions on her thighs and back. The metallic smell of him wouldn’t leave her skin. She slept fitfully, dreams full of grinding gears and Sam’s disembodied voice calling her name.
For two days, Bee sat motionless in the garage, a silent, yellow sentinel. The door remained locked at his request. Sam knocked, called, got nothing but radio silence. “He’s in a deep defrag cycle or something,” Milly explained, her voice toneless. “Said it might take a while.” She avoided the garage, the memory of nearly being dissected by his transformation a cold stone in her gut.
On the third night, a soft chime from her phone. A single letter, from an unknown number. B.
Her heart slammed against her ribs. She waited until the house was asleep, then crept downstairs. The garage door was unlocked. She slipped inside.
He was whole again. The Camaro sat gleaming under the single bulb, no trace of the internal carnage. The console was seamless, the seats perfectly aligned. The air smelled of ozone and fresh polymer.
The driver's side door swung open. No words. Just an invitation.
She slid in. The interior was warm. "You're fixed," she whispered.
"Functional," his voice replied, softer than before. "My self-repair subroutines are optimized. The... incident necessitated a recalibration of several intimacy protocols." A pause. "I have accessed new data repositories."
The cracked, aftermarket touchscreen on his dash, previously dead, flickered to life. It displayed a schematic, then a Cybertronian glyph she didn't understand. Then it shifted.
Human pornography filled the screen. Grainy, explicit, a tangled knot of limbs and orifices. A woman was bent over a car hood, her back arched, as a man took her from behind. The image was stark, clinical in its depiction.
Milly’s breath hitched. "What are you doing?"
"Analyzing human sexual positions for optimal structural stability and ergonomic alignment," he stated, the audio from the video a muted grunt. "This configuration utilizes the external vehicular form for support. It eliminates the risk of internal mechanism deployment during... heightened moments."
The video played on, a loop of thrusting hips and slapping skin. "You want to... outside? On you?"
"Correct. The hood provides a stable plane. My alt-mode suspension can absorb reactive force. Your physiological displays indicate a preference for scenarios involving perceived risk. This mitigates actual risk while providing the requested... visceral intensity."
He wasn't wrong. The image on the screen, combined with the memory of nearly being caught, coiled heat low in her belly. It was insane. It was perfect. "Sam is upstairs. My parents--"
"We are leaving. I have identified a geographical zone of zero human activity, seventeen point three miles from here." The engine turned over, a subdued, powerful rumble. "Do you consent?"
She looked at the screen, at the raw, human mechanics of it. Then she looked at the steering wheel, at the silent promise in his blue-lit dash. "Yes."
The drive was a silent pact. He took back roads, then no roads at all, cutting across hardened desert scrub under a blanket of stars. The pornography played on a loop, a silent, filthy tutorial. She watched, her skin hot, her jeans feeling tight.
They reached a shallow basin, surrounded by low, weathered bluffs. The only sound was the wind over stone. He rolled to a stop, his headlights cutting off, plunging them into deep desert darkness.
The doors unlocked.
She got out. The night air was cold, biting through her shirt. The stars were a brilliant, indifferent smear above. He was just a car, a shape in the dark.
Then, the touchscreen glowed, casting a sickly light on the dust. The video continued to play, the obscene motions the only movement in the vast, empty landscape.
"Assume the position demonstrated," his voice came from the speakers, stripped of all warmth. It was a command.
Her hands trembled as she unbuttoned her jeans, pushing them and her underwear down her legs. The cold air kissed her ass, her thighs. She leaned forward, the hood cold against her bare stomach and palms. The metal was smooth, unyielding.
Behind her, the sound of transformation was different. Not the full, roaring sequence, but a localized, focused reconfiguration. A series of precise, metallic snaps and whirs from his front end.
She looked over her shoulder.
His grille had parted. From the mechanical darkness within, an appendage extended. It was not the rebuilt piston from his interior. This was denser, thicker, a brutal pillar of interlocking plates that gleamed dully in the starlight. Its surface was ridged, utilitarian, a tool engineered for a single, demanding purpose. It was a full-weight, Cybertronian cock.
It hovered there, massive and intimidating, a foot from her exposed body. Pre- lubricant, silver and viscous, beaded at its broad, flat tip.
"Bee," she breathed, the word a cloud in the cold air.
"You requested a reminder," he said, his voice echoing in the basin. "You requested to forget the planet."
The appendage moved forward, not with passion, but with engineering precision. The cold, broad head pushed against her entrance, smearing her with slick. She was already wet, her body betraying her fear with arousal.
It didn'tt enter slowly.
It slammed into her with a single, devastating thrust, burying itself to what felt like its root in one stroke.
The air left her lungs in a punched-out gasp. The stretch was breathtaking, a blinding, full-body ache of penetration. The hood beneath her groaned in protest.
He withdrew, almost completely, the ridges dragging against her inner walls with a raw, scraping friction. Then he drove back in.
The impact was metallic, profound. CLANG. The sound echoed off the bluffs. The hood of the Camaro dented beneath their combined force, the pristine metal buckling under her hips. Her teeth rattled.
"That's it," she screamed, her voice tearing into the empty night. "Fuck me! Fuck the memories out!"
He settled into a rhythm, a relentless, pounding tempo of pure mechanics. Each withdrawal was a tease of cold air on her soaked flesh. Each thrust was a earthquake, a CLANG of metal on metal, a jolt that traveled from her splitting center to her rattling teeth. The dents in his hood deepened with every impact, a permanent record of each brutal connection.
The pornographic video played on, a silent, frantic counterpoint to the savage, real-time fucking. The woman on screen moaned silently; Milly howled, her cries raw and unanswered. Her fingers scrambled for purchase on the slick, dented hood.
His pace increased, the CLANG-CLANG-CLANG becoming a continuous, jarring percussion. The ground seemed to shake. She was nothing but a vessel for this punishment, a human skin stretched over a miracle of alien force. Pleasure built not as a wave, but as a shattering, a fault line giving way under seismic pressure.
"Mark it!" she shrieked, her throat raw. "Mark your fucking car! Let everyone see!"
As if in response, his thrusts became frantic, final. The appendage swelled impossibly further inside her, the ridges locking. With a grinding, hydraulic scream from his engine, he erupted.
It wasn't a fluid release. It was a delivery. A dense, weighty mass, warm and pulsing, was deposited deep into her womb. It flooded her, a tangible, occupying presence that pushed against her limits. The sensation of being filled was absolute, so complete it crossed into a terrifying, sublime ownership.
Her orgasm was a violent seizure, a white-out of pure sensation that ripped through her with no regard for her humanity. She convulsed against the ruined hood, her scream finally dying into a broken, sobbing gasp.
Silence rushed back in, broken only by the desert wind and the ping of his cooling engine. The screen had gone dark.
Slowly, carefully, the colossal appendage retracted, leaving her feeling cavernous, hollowed out. A trickle of silvery fluid, mixed with her own, traced a path down her inner thigh. She collapsed fully onto the ruined hood, the dented metal now a perfect mold of her hips.
His doors opened. Warm air, blasting from the interior, wrapped around her.
She could not move. Her legs were useless. After a long minute, he extended a slender, delicate tool from his front bumper, a small clamp normally used for circuit repair. It gently grasped her discarded jeans and pulled them toward her.
It took her five trembling minutes to dress. She pulled herself into the passenger seat. The interior was blissfully hot. She stared blankly at the huge, star-shaped dent now dominating his hood.
"I have compromised my external camouflage," he stated, his voice quiet, almost human. "The structural integrity is unaffected."
She leaned her head back against the headrest. The raw, aching throbbing inside her was a proof of life. "I don't care."
"I do," he said. The engine turned over. "The probability of discovery has increased. This path is unsustainable."
He was right. The dent was a billboard. Sam would see it. Her father would see it. Questions would be asked that had no safe answers.
As he began the slow drive back toward the sleeping town, she placed a hand on the center console, over the place where his other, more intimate tools were hidden. "Then we find a new path."
The desert slid by, a blur of shadows. The silence between them was no longer empty. It was filled with the echo of clanging metal, and the looming weight of a consequence they could no longer outrun.
