Jake and his friend Leo join a medical study where they are used by fuck machines hard

Chapter 1: Synchronized Submission

The air in the chamber always smelled like ozone and something else, something metallic that Jake could never quite place. It clung to the back of his throat. The surface beneath him was cool, unforgiving stainless steel, and the straps across his wrists and ankles were padded but unyielding. A dull, rhythmic whirring filled the room, a sound so constant it had started to fade into the background of his own pulse.

Next to him, Leo let out a short, sharp breath. “You still with me, man?”

“Yeah.” Jake’s voice was tight. He stared at the seamless ceiling, at his own reflection blurred in the polished surface. His body was a tense line, every muscle coiled. “Just thinking about what I’m gonna buy. New shocks for the bike, probably.”

“Priorities,” Leo muttered, then hissed as a new cycle began.

The machines were sleek, impersonal things of gleaming arms and calibrated pistons. They moved with a silent, hydraulic efficiency that was its own kind of violence. There was no malice in it, which almost made it worse. Jake’s body jolted forward against the restraints, a purely involuntary reaction to the foreign, invasive rhythm. A sheen of sweat made his skin stick to the steel table.

He heard Leo bite back a grunt, then a low, dark chuckle.

“Science, right, Jake?” Leo’s words were strained, forced out between clenched teeth. His head was turned toward Jake, a smirk playing on his lips that didn’t quite reach his eyes. “The pursuit of knowledge. Human sexual response under… what did he call it? ‘Controlled stimulus.’”

“Five thousand dollars,” Jake ground out, closing his eyes. He focused on the number. It was a real number. It was transmission repairs and three months of rent and not having to call his mom for a loan. The sound of the machinery became the sound of cash registers. The mechanical push and pull was just… a job. A weird, fucked-up, deeply personal job, but a job. He repeated it in his head like a mantra. Five thousand. Five thousand.

“Think doc’s watching?” Leo asked, his voice gaining a theatrical quality. “From his little observation booth? Taking notes? ‘Subject Gamma demonstrates elevated heart rate paired with profoundly creative swearing.’”

A real laugh escaped Jake, harsh and surprised. It loosened something in his chest. “He’s probably just checking his emails. We’re not that interesting.”

“Speak for yourself. I’m a fascinating specimen.”

Another cycle. Jake’s knuckles were white where he gripped the edges of the table. The boyish charm usually present on his face was gone, replaced by a stark, focused neutrality. He had to detach. He imagined himself floating near the ceiling, looking down at some other guy’s body strung up on this absurd contraption. That guy was earning five grand. Good for him.

The hum of the machines shifted pitch, synchronizing. The movement became deeper, more insistent. Jake’s breath hitched. His easygoing nature, the thing that had gotten him through a lot of life’s bullshit, felt thin and fragile here, stretched over a core of cold, humming metal.

“Okay,” Leo breathed, the sarcasm finally draining from his voice. “Okay, that’s… new.”

Jake could only nod, his jaw locked. The clinical nature of it all was the worst part. The spotless floors, the frosted glass of the observation window, the gentle whir of the white noise machines meant to hide their sounds from anyone outside. It made the whole thing feel like a car repair. Just a system, being tested. His body wasn’t his; it was a bundle of wiring and plumbing, and Dr. Aris Thorne was the technician running diagnostics.

He thought of Dr. Thorne. Mid-forties, muscles that spoke of a dedicated gym habit, a gaze so intensely focused it could feel like a physical touch. They’d joked about it after the first screening, how it was easier to take your clothes off for someone who looked like that. It was a defense mechanism, a way to laugh at the vulnerability. But here, now, with the machines doing their work, the thought of that observational, analytical heat watching from behind the glass was strangely isolating. He wasn't a person to Thorne. He was a data point. A successful trial run.

Leo started humming some stupid pop song, off-key and broken by his breathing. It was so Leo. Using irony as a shield, turning the profoundly awkward into a bad punchline. Jake clung to the sound. It was human. Real.

The chamber door hissed open.

Both of them flinched, a sudden, shameful movement they couldn’t control. The machines continued, undisturbed.

Dr. Aris Thorne stood in the doorway, a tablet held in one strong hand. He didn’t smile. His eyes, a cool, assessing gray, scanned the readouts on a wall panel before flicking to them. To their restrained, sweat-slicked forms. There was no embarrassment in his look, no recognition of the intimacy of the scene. It was pure assessment.

“Heart rates are elevated beyond the projected median for this phase,” he stated, his voice calm and even. A clinical observation. “Gamma, your respiratory pattern is irregular. Try to maintain steady breathing. It affects the pelvic floor tension metrics.”

Gamma. Jake. He was Gamma.

Leo, Beta, let out a sound that was half-laugh, half-groan. “You try breathing steady with a robot fist–”

“The apparatus is a precision-guided actuator, not a fist,” Thorne corrected calmly, tapping his screen. “The data is compelling. You’re both producing significant neurological feedback. Far above the control group.” He finally looked at them, not as men, but as sources of that data. A spark of something that looked like satisfaction lit his eyes. “Proceed.”

The door hissed shut.

Silence swallowed the room again, broken only by the whir and the thick, ragged sound of their breathing. The cool air from the hall had swept in, raising goosebumps on Jake’s heated skin.

“Significant neurological feedback,” Leo echoed, his voice hollow now. The humor was gone, burnt away by the doctor’s detached intrusion. “He says the sweetest things.”

Jake didn’t answer. He was back inside the number. Five thousand dollars. He could see the stack of bills in his mind. He could feel the weight of it in his hand. He could smell the motor oil from his bike’s new shocks.

His body jerked against the straps again, a puppet on a very expensive, very scientific string. He stared at the ceiling, at his own blurred face, and willed himself to disappear into the money. It was getting harder. A stubborn, quiet part of him, a part he usually kept well buried, was starting to push back against the straps, against the whirring, against the word ‘Gamma.’ It was a small, hot coil of anger.

It felt more real than the money. And that scared him more than any machine ever could.

The session in the main chamber ended not with a climax, but with a slow, mechanical whine fading into silence. The restraints released with a soft pneumatic hiss. Jake lay there, staring at the ceiling, his body humming with a strange, hollow ache. The five thousand dollars felt like coins made of lead in his mind.

“Show’s over,” Leo croaked, pushing himself up on trembling elbows. His smirk was back, but it was brittle, a cracked glaze over exhaustion. “Until next time.”

The door opened again. Dr. Thorne entered, his shoes silent on the polished floor. He didn’t look at their faces, his eyes scanning the tablet screen. “The data from that cycle was anomalous. Promising, but anomalous. I require a more controlled environment to isolate the variables.”

Jake sat up, the cold steel seeping into his palms. “What does that mean?”

“It means follow me,” Thorne said, turning on his heel. His tone left no room for question.

They exchanged a look—a flicker of shared dread passed between them—before stumbling off the tables. The white paper gowns they’d been given felt absurd now, crinkling as they shuffled after the doctor’s retreating back. He led them down a narrower, cooler hallway, past rooms with closed doors and muted indicator lights.

Thorne stopped at an unmarked door, punched a code, and ushered them inside. This room was smaller, darker. The lighting was lower, more focused. Instead of the multiple, smaller apparatuses, two larger, more complex machines dominated the center of the room. They were all harsh angles and articulated arms, with a broader array of sensors and what looked like… additional attachments. A pronounced medical scent, sharp and astringent, hung in the air.

“Assume the positions,” Thorne said, gesturing to two newly equipped tables. These had additional straps at the shoulders and thighs, and peculiar headrests that angled the neck back.

“Doc, this looks… intensive,” Leo said, his attempt at lightness falling flat.

“It is. Lie down.”

Jake’s stubborn streak, that quiet coil, tightened in his gut. But the ghost of the money, the sheer weight of his empty bank account, pushed him onto the table. The cold bit through the paper immediately. Leo followed suit, his usual commentary dying before it reached his lips.

Thorne worked with efficient, impersonal hands. He fastened the restraints himself, checking each one with a clinical tug. The strap across Jake’s forehead was the worst, forcing his head into the cradle. He could only see the ceiling and the reflective sheen of a large, darkened observation window.

“This phase involves synchronized dual-axial stimulation and pharyngeal response measurement,” Thorne explained, his voice close to Jake’s ear as he adjusted a sensor on his chest. “You will experience a deeper physiological engagement. The goal is peak synaptic feedback.”

“Peak synaptic feedback,” Leo repeated from the other table, his voice muffled. “Can I get that on a t-shirt?”

Thorne ignored him. He moved to a control panel on the wall. A low, powerful hum vibrated through the tables, up through Jake’s spine. He saw the machines articulate, repositioning themselves with a series of soft clicks. The attachments were larger, more intimidating in their precision.

“Begin,” Thorne said, and his voice held a note of something new. Not excitement, but a deep, focused hunger.

The first wave was a shock that drove the air from Jake’s lungs. It wasn’t just the invasion, which was deeper, more relentless, but the sheer mechanical force of it. His body arched against the restraints, a strangled sound caught in his throat. Next to him, he heard Leo gasp, then swear, the word breaking apart.

The rhythm established itself, a brutal, synchronized piston stroke. Jake squeezed his eyes shut, but there was no escape into the darkness. Every nerve ending was a live wire, broadcasting pure, overloaded signal. The money vanished. His bike, his rent, his pride—all of it was atomized under the raw, data-driven force of the machines.

Then, a new motion. The headrest tilted further. An articulated arm, tipped with a smooth, tapered module, moved into his limited field of view. It aligned with his mouth. His mind screamed a refusal, but his body was pinned, helpless.

“Pharyngeal measurement commencing,” Thorne’s voice came over a speaker, calm, absorbed.

The module pressed forward. Jake clenched his jaw, a last, futile act of defiance. The machine applied steady, increasing pressure. His muscles trembled, then yielded. The sensation of it sliding deep, triggering a gag reflex he couldn’t act on, was a new kind of surrender. Tears welled in his clenched eyes from sheer physiological overwhelm. He was being consumed by the rhythm, filled by it, his body a resonating chamber for the deafening mechanical pulse.

Time dissolved. The two hours were not minutes and seconds, but a continuum of strain and release, of overwhelming sensation and the numb void that followed each wave. He drifted in and out of a strange, shattered awareness. He heard choking, wet sounds and realized they were his own. He heard Leo make a noise like a sob once, then a raw, fractured laugh.

Through the blur, he saw Thorne. The doctor was standing at the observation window now, his face illuminated by the glow of a separate monitor. He wasn’t looking at them, not really. He was staring at the cascading data on the screen, his expression one of rapt, almost reverent fascination. A slight, unbidden smile touched his lips. He was beautiful in that moment, and the thought filled Jake with a despair so profound it felt like ice in his veins.

The machines did not tire. They did not vary. They were perfect.

When the hum finally ceased, the silence was louder than any noise. The arms retracted with a soft, final hiss. The restraints loosened.

Jake lay completely spent. He felt hollowed out, scraped clean. The cool air of the room felt like a brand on his sensitized skin. He turned his head, a painful effort, and saw Leo staring blankly at the ceiling, tears cutting clean tracks through the sweat on his temples.

Thorne approached. He placed a hand on Jake’s shoulder, a clinical gesture to check his pulse. His touch was warm. “Remarkable,” he murmured, more to himself than to them. “The parallel neurological pathways… the data is exquisite.”

He walked to the door, then paused, looking back at his two subjects lying broken on the tables. “Rest. Hydrate. Same time tomorrow.” He left.

The door clicked shut.

For a long time, neither of them moved. The only sound was their ragged, uneven breathing.

“Leo?” Jake’s voice was a ruined thing, raw and unfamiliar.

“Yeah.”

“I want to come back tomorrow.”

The words hung in the antiseptic air, ugly and true. Jake stared at the ceiling tiles, counting the tiny perforations, waiting for Leo to tell him he was insane.

Leo finally turned his head on the table, the movement slow with exhaustion. “Yeah,” he rasped. “Me too.”

It wasn’t enthusiasm. It was surrender. A grim acknowledgment of the same empty bank accounts, the same dead-end options waiting outside this sterile maze. The silence that followed was thicker than the white noise.

A different door slid open with a soft sigh. A woman in pale blue scrubs stood there, her face a careful mask of neutral efficiency. She wasn’t Thorne; her eyes held a flicker of something resembling pity, quickly banked.

“Recovery is this way,” she said, her voice gentle but firm.

Moving was a process. Jake’s limbs felt like they belonged to someone else, heavy and uncoordinated. The paper gown was damp and clung to him as he swung his legs over the side of the table. The floor was cold on his bare feet. He glanced at Leo, who was moving with the stiff caution of an old man. They didn’t speak.

The recovery room was only marginally less clinical. Soft, gray couches instead of steel tables. A low hum of filtered air instead of machinery. A carafe of water and glasses sat on a low table. It felt like a waiting room in purgatory.

“Sit. Hydrate. You’ll feel faint if you stand too quickly,” the nurse instructed. She handed each of them a foil-wrapped electrolyte packet and a damp, cool towel. “Use this. You have thirty minutes before your debrief and payment disbursement.”

She left, and the door clicked shut, locking from the outside.

Jake sank onto a couch, the cool microfiber a shock against his skin. He wiped his face with the towel, the smell of clean linen overwhelming the lingering ozone. He watched his hands tremble as he poured water. The glass clattered against his teeth.

Across from him, Leo drained his own glass in one long pull, then crumpled the foil packet with a vicious crunch. “Exquisite data,” he mimicked, his voice still hoarse. “He sounded like a fucking sommelier tasting a good Burgundy.”

A weak laugh escaped Jake. It hurt his throat. “What’s the fancy word for being fucked by a robot?”

“Technically proficient?” Leo offered, leaning his head back and closing his eyes. The bruises of exhaustion were already darkening under his lashes.

They sat in the quiet, the enormity of what they’d just done settling over them like a fine dust. Jake’s mind replayed it in sharp, brutal fragments: the cold of the restraint, the precise angle of Thorne’s smile, the feeling of his own body betraying him, responding to the programming despite the revulsion curdling in his gut. He felt a hot wash of shame, followed by a colder, harder resolve. They’d known it would be weird. They hadn’t known it would feel like being erased.

“You okay?” Jake asked, the question inadequate.

Leo opened one eye. “Define okay. Physically? I feel like I got hit by a train made of science. Mentally?” He gestured vaguely at the room. “I’m in a secret lab getting paid to be a human stress ball for a hot doctor with a god complex. It’s a Tuesday.”

“It’s Thursday.”

“See? I’ve lost all concept of time. That’s probably in the brochure.” Leo sat forward, his expression turning serious. The sarcasm bled away, leaving something raw and worried underneath. “You meant it, though. About tomorrow.”

Jake looked at his hands, the knuckles scraped from where he’d gripped the table. He nodded. “The money’s real, Leo. It’s in the bank. I checked after the first session.”

“I know it’s real. My half is sitting there looking at me. It’s the other part I’m worried about.” Leo leaned in, his voice dropping. “That second room… that wasn’t in the consent forms. Not the specifics. The head thing? The… pharyngeal whatever?”

“He said it was for measurement.”

“He says a lot of things.” Leo’s gaze was intense. “What happens when he needs to measure something else? Something worse? Where’s the line, Jake? Is there one? Or do we just keep cashing checks until we can’t look in the mirror anymore?”

The question sat between them, unanswerable. Jake wanted to argue, to say they’d walk away if it got too messed up. But the truth was, he didn’t know where his own line was. Five thousand had been the line. Then it was ten. What would it be for fifteen? For twenty? The hollow ache in his body was a physical debt, and the money was the only currency that could settle it.

The lock disengaged with a sharp buzz. The nurse returned, this time with a digital tablet. “Dr. Thorne will see you for final vitals and payment release. One at a time.” She looked at Jake. “You first.”

He stood, his legs steadier now. He followed her down another hallway, this one lined with framed diplomas and densely worded medical patents in Thorne’s name. They stopped at an office door.

Thorne’s office was a surprise. It was warm, lined with real books, a deep rug on the floor. He sat behind a polished wood desk, looking more like a successful architect than a researcher. He gestured to a chair.

“Jake. Please, sit.” His demeanor was different here; still intense, but with a veneer of professional courtesy. “Your resiliency metrics are exceptional. Truly. Far surpassing our initial projections.”

“Great,” Jake said, the word flat.

Thorne steepled his fingers, studying him. “The study is entering a new phase. Deeper neurological mapping. It requires a higher degree of… commitment. From both parties.” He slid a single sheet of paper across the desk. “An amendment to your contract. It details the expanded protocols and the corresponding compensation adjustment.”

Jake’s eyes skipped to the bottom of the page. The number was a shock, a jolt of pure adrenaline that bypassed his brain and shot straight to his lizard core. It was life-changing money. Debt-obliterating money. A year of freedom money.

His mouth was dry. “What kind of expanded protocols?”

“Sensory deprivation elements. Paired biometric feedback loops. It’s about isolating pure response, stripping away environmental noise.” Thorne’s eyes glittered with a fervent light. “We’d be breaking new ground. You and Leo are uniquely suited.”

Jake looked at the number again. He thought of his mother’s tired voice on the phone last week, asking, ever so gently, if he was making ends meet. He thought of the eviction notice tucked under a coffee mug in his kitchen. The cracked screen of his phone. The relentless, grinding pressure of having nothing.

He saw the line Leo had asked about. It was right there, printed in stark black ink. He was already on the other side of it.

“Do I have to decide now?”

“I need an intent to proceed. The next session is tomorrow. Sign now, or the offer reverts to the original contract terms.” Thorne pushed a pen toward him.

The pen was cold, heavy. A quality instrument. Jake picked it up. He didn’t read the fine print. He scrawled his name on the dotted line, the letters jagged and unfamiliar.

“Excellent.” Thorne took the paper, his smile genuine, radiant. “You’re making the right choice. For science.”

Back in the recovery room, Leo took one look at his face and knew. “You signed it.”

“Yeah.”

“How much?”

Jake told him. Leo blanched, then let out a low whistle. He didn’t ask what for. He just leaned back, staring at the ceiling. “We’re gonna need it,” he said finally, his voice quiet. “For the therapy.”

Later, dressed in their own clothes which felt strangely foreign against their skin, they stood at the facility’s discreet rear exit. The evening air was cool, a shock after the chamber’s controlled climate. The city’s normal sounds—distant traffic, a siren, the rustle of trees—felt overwhelmingly loud and chaotic.

Jake fumbled for his keys, the metal cold in his sweaty palm. He looked back at the unmarked concrete façade of the building, a blank monolith hiding its secrets. He could still feel the phantom rhythm in his bones, a ghost of the machine’s pulse.

Leo lit a cigarette, the flame bright in the dusk. “So,” he said, exhaling a plume of smoke. “We’re doing this.”

“We’re doing this,” Jake echoed. It wasn’t a question anymore.

He got into his car, the familiar seat a small comfort. As he drove away, the image in the rearview mirror wasn’t of the building fading into the distance. It was of Thorne’s satisfied smile, and the cold, heavy weight of the pen in his hand. The money was already in his account. It felt less like a reward, and more like a down payment on a piece of himself he hadn’t known was for sale.
