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

Chapter 6: The Reckoning: No More Limits

Three days later, the air in the chamber still carried the ghost of their sweat. The cracks in the floor from the shaking platform were still there, like fresh scars. Jake ran a finger along one, feeling the sharp edge. His body didn’t hurt anymore. Not in the way it had. The soreness was gone, replaced by a strange, humming emptiness. It was worse.

Leo was already strapped down on his slab, staring at the new attachments. They weren’t Engrams. They were brutal, functional things of blackened steel and hydraulic pistons. Two arms, each ending not in a smooth, tapering probe, but in a blunt, mechanical wedge.

“Hydraulic anal spreaders,” Thorne said, his voice echoing in the space. He looked different. He’d been sleeping here, Jake guessed. A rumpled lab coat was thrown over a chair in the observation room, a cot visible behind the glass. His eyes had a feverish brightness. “Posterior dilation to a previously unattainable degree. It will… make space.”

“Make space for what?” Leo asked, his tone light but his eyes fixed on the wedges.

“For everything,” Thorne said, simply.

The prep was silent. The nurses avoided their eyes. When they were restrained, the cold gel applied, Thorne descended from the observation deck. He stood between the slabs, looking at them not as a doctor, but as a sculptor assessing his marble. “The data from the last session was…”

“Ruinous,” Leo supplied.

“Transformative,” Thorne corrected. “You adapted. Not just physiologically. Neurologically. Your pain tolerance thresholds have recalibrated. Your pleasure centers are now firing in synchronicity with… extreme stimulus.” He reached out, adjusting a strap on Jake’s wrist. His touch lingered. “You asked for the machine’s full power. You got it. You broke my chamber.” A faint, proud smile touched his lips. “Now we see what you do with the architecture.”

He walked back to the console. “Phase Four: Dilation and deep-structure engagement.”

The hum began. It was lower. A subsonic grumble that vibrated in Jake’s molars. The spreaders descended. They were cold, even through the gel. They pressed, blunt and insistent, against him.

There was no finesse. No gradual penetration. The wedges engaged with a hard, clinical pressure. Then, with a smooth hydraulic hiss, they began to open.

It was a stretching unlike anything. Deeper, more fundamental. It wasn’t about depth. It was about width. A slow, inexorable pulling apart. Jake heard his own breath whistle between his teeth. It wasn’t sharp pain. It was a profound, aching strain. The feeling of being opened, not entered.

Leo made a low, guttural sound. “Oh, wow. Okay. That’s… new.”

Jake turned his head. Leo’s face was flushed, his jaw tight. He was watching the spreaders work in a mirror angled above. “It’s like… reverse engineering.”

The ache built. It was vast, dull, consuming. Jake felt his body resisting, the clench of muscles designed to keep things tight, being overruled by relentless steel. He was being made into an open channel. The hollow feeling inside him yawned wider, echoing the physical space being carved out.

“Threshold one achieved,” Thorne’s voice crackled. “Preparing Engram reactivation.”

The spreaders held their position, a permanent, aching stretch. Then, the familiar, deeper hum of the Engrams powering up resonated through the slabs. Jake’s heart hammered. They were already so open. So vulnerable.

The Engram touched him. The pressure, which had always been a challenging, focused nudge, was different. There was no resistance. The machine slid into the space the spreaders had made with a shocking, smooth ease. It went deep, impossibly deep, without the searing fight. The sensation was less about breach and more about… occupation. A total, deep-structure filling.

“Jesus Christ,” Leo whispered, the words trembling.

The machine began to move. With the spreaders holding him open, every stroke was longer, smoother, more direct. It touched places inside him that had been hints before, shadows of sensation. Now it was hammering against them, a piston in a perfectly machined cylinder. The neuro-stim crackled, a live wire dropped into a well of new, raw nerves.

It was too much. It was not enough.

“Thorne!” Jake yelled, the sound torn from him.

“Subject Alpha?”

“You’re holding back!” Jake gasped. The machine was pounding, deep and true, but it was rhythmic. Predictable. “I can feel it! It’s reading the spreaders’ limit! It’s staying safe!”

Leo laughed, a wild, broken sound. “He’s right! This is just fancy plumbing! You rebuilt the pipe but you’re still using the same water pressure! Give it the chaos! Give it what we broke before!”

From the observation deck, a long silence. Then, Thorne’s voice, raw with something that sounded like fear. Or awe. “The synchronization algorithm is compensatory. It’s preventing overstress to the dilated tissue.”

“Disengage it,” Jake demanded. His body was on fire, his mind screaming for the edge. “Let the systems fight. Let the spreaders pull. Let the Engram push. Let them tear me.”

“The risk of—”

“Is mine!” Jake roared, straining against the straps. “You want your data? Watch what happens when the left hand doesn’t know what the right is doing!”

Another silence. Longer this time. They could hear Thorne breathing heavily over the mic. The machines maintained their brutal, perfect rhythm.

Then, a series of clicks.

“Synchronization disengaged,” Thorne said, his voice barely a whisper.

For two strokes, nothing changed.

Then, the spreaders twitched. A slight, independent hydraulic shiver. The Engram, now operating on its own savage algorithm, chose that moment to drive forward with a ferocious, deeper lunge.

The sensations collided.

The spreading pulled. The machine shoved. The feelings didn’t combine; they warred. A deep, stretching ache from the spreaders clashed with a piercing, internal thrust from the Engram. His body was a battlefield between two opposing forces. The rhythm disintegrated into noise.

The Engram began its variable, unpredictable pattern—shallow flutters, deep, grinding holds, sudden violent retreats. The spreaders responded to the stress with minute, automatic adjustments, clamping tighter or easing open a fraction. They were not working together. They were reacting to each other’s violence.

It was chaos. Beautiful, annihilating chaos.

Jake’s world dissolved into a storm of conflicting sensations. He was being pulled apart and hammered together in the same instant. The neuro-stim flashed erratically, a strobe light of agony and blinding, white-hot pleasure. He couldn’t breathe. He couldn’t think. He could only feel the war inside him.

Leo was sobbing, great heaving gasps between the machine’s drives. “Yes! Fuck! That’s it!”

Thorne was speaking, but his words were lost in the roar. He was chanting data. Pressure readings. Micro-tears. Neurological spike intervals. It was a prayer to the chaos.

Jake felt a giving way. Not a tearing, but a softening. A surrender of some last, deep internal barrier. The warring sensations didn’t merge; they elevated. They became a single, coherent symphony of brutal excess. The spreaders weren’t an enemy. They were the reason the Engram could reach the fathoms it now did. They were collaborators in his ruin.

He climaxed violently, a dry, wrenching convulsion that had no release but wave after wave of overwhelming sensory overload. It didn’t stop the machines. It was just another note in the cascade.

Time became meaningless. There was only the duel of metal inside him, and the bright, shattered point of his consciousness observing it from somewhere far away.

When the machines finally whined down to stillness, the silence was deafening. The spreaders retracted with a slow, hydraulic sigh, leaving him feeling gaping, empty, and profoundly altered. The Engram withdrew, a slick, final exit.

He lay there, ruined. Beside him, Leo was making small, wet sounds against the slab.

Thorne appeared. He wasn’t walking. He was stumbling down the stairs. He fell to his knees between the slabs, his hands shaking as he touched Jake’s thigh, then Leo’s arm. He was crying, silent tears cutting tracks through days of grime on his face.

“The data…” he rasped. “You… you sustained it. You didn’t break. You…” He looked up at them, his expression one of shattered devotion. “You converted the strain. You made dissonance into… into music.”

Jake slowly turned his head. He felt loose. Unmade. He looked at Leo, who gave him a weary, triumphant smile. He looked down at Thorne, the powerful doctor on his knees between them, weeping over his victorious, broken subjects.

He didn’t feel like a subject. He felt like a god. A shattered, used, empty god.

“What’s next?” Jake asked, his voice a rough scrape in the new quiet.

Thorne wiped his face, a smear of tears and oil. He looked at the broken chamber, the stained floor, the two spent young men on the slabs. A wild, unstoppable light grew in his eyes.

“Next,” he said, his voice firming with terrifying conviction, “we redesign the machines.”

“Next,” he said, his voice firming with terrifying conviction, “we redesign the machines.”

Jake stared at the cracked ceiling panels, his body humming with a strange, hollow fullness. “Redesign them how?”

“Here,” Thorne gestured vaguely at the sterile chamber, “is a controlled environment. It’s a language I wrote.” He stood, his knees popping, and looked at them with that fiery, unhinged focus. “Your bodies have learned that language. You speak machine.” He paced, a caged animal. “We need a dialect you can’t predict. An environment that doesn’t follow my protocols.”

Leo coughed, pushing himself up on trembling elbows. “You’re gonna put us in a different room? One with, like, shag carpet and mood lighting?”

“Not a room.” Thorne stopped, his eyes locking onto theirs. “A friend of mine runs a research outpost. Biomechanical interfaces. It’s… less refined than this.”

A week later, they stood in the golden haze of a late afternoon, not chrome but dust. The air didn’t smell of ozone. It smelled of hay, of warm animal hide, of damp earth. Thorne’s “friend” was a sharp-eyed woman named Mara who sized them up like livestock. The “outpost” was a refurbished barn, the back half converted into something that looked like a veterinary surgery crossed with a mechanic’s garage.

“This is the new machine,” Thorne said, his voice low with reverence.

They weren’t looking at steel. They were looking at flesh. Ten Belgian draft stallions stood in individual stocks, their powerful haunches gleaming, their breath pluming in the cool barn air. They were impossibly huge. The sound was a low, shifting rumble of muscle and weight. A custom-built timber frame, like a massive, inverted sawhorse, dominated the center space.

“You’ve got to be fucking kidding me,” Jake whispered.

“Biomechanical,” Leo murmured, his intellectual curiosity overriding his horror. “The horse provides the kinetic force. The frame and the, ah, interface provides the direction.”

Mara walked over, patting the flank of the nearest stallion. “These boys are prepped and ready. We use synthetic collection apparatus for breeding, but Thorne’s modifications are… specific.” She pointed to the timber frame. “You’ll be secured there. The interface will align them. It’s about bio-rhythms, not hydraulic timers.”

Thorne was already at a control panel mounted on a barn post. “The chamber had limits. This force is organic. It’s variable in a way pistons can’t be. It’s living power.”

The preparation was crude. They were told to strip. The cool air of the barn raised goosebumps on their skin. Mara applied a thick, clear gel herself, her touch brisk and impersonal. The timber of the breeding bench was smooth, worn by weather and use, not machining. The restraints were heavy leather straps.

As Jake leaned over the thick beam, the reality of it crashed into him. This was agriculture. This was breeding. He was being strapped into a device built for animals.

“This is next-level psycho shit, Thorne,” Leo said, his voice tight as a strap cinched across his back.

“It’s the next phase,” Thorne corrected, his gaze fervent. “You asked for uncharted territory.”

Mara guided the first stallion out of its stock. The animal was calm, docile even, but the sheer mass of it was breathtaking. It clopped slowly toward the frame, led by a harness. The “interface” Thorne designed became clear: a guiding chute of flexible polymer that would direct the stallion’s natural motion.

Jake watched it approach from his position, his heart slamming against the timber. This wasn’t a machine he’d learned. This was a thousand pounds of muscle and instinct.

The stallion mounted the frame.

The world narrowed to sound and pressure. The animal’s weight settling onto the support structure made the whole timber frame groan. The heat coming off its body was immense. Jake could smell its sweat, hear the deep sniff of its breath.

There was no hum. Just a shifting, powerful presence. Then, a blunt, searching pressure.

It was different. It wasn’t steel. It was a living, pulsing heat. It was softer, yet somehow more substantial. The initial push was cautious, almost confused. Then instinct took over.

The thrust was a fluid, powerful drive of pure animal muscle. It was slower than the machine’s hammering, but deeper, more deliberate. It pushed into the space the spreaders had carved and kept going, a relentless, living pressure that didn’t stop at a programmed depth. It stopped when the stallion was fully seated, a complete, overwhelming occupation.

Jake cried out, a sound lost in the barn’s vastness. It wasn’t pain. It was the shock of the organic. The sheer, lived-in warmth of it.

The rhythm began. It wasn’t metronomic. It was a living, breathing tempo. The stallion’s thrusts were long, deep surges followed by moments of full, embedded stillness where Jake could feel the animal’s heat throb inside him. It was less like being fucked by a machine and more like being claimed by a force of nature.

“First subject integration successful,” Thorne’s voice came, hushed, over a speaker. “Neurological sync is… it’s beautiful. The feedback loops are chaos. Perfect chaos.”

The stallion finished with a final, shuddering drive and dismounted, guided away by Mara. The emptiness it left was a vacuum. Before Jake could even gasp, the next one was being led in.

The second was different. Stronger, more impatient. Its rhythm was quicker, harder. The third was slower, almost lazy in its depth. Each was a unique lesson in raw, unscripted power. Each left him more open, more used, more thoroughly rewritten.

Leo’s sounds had shifted from sarcastic commentary to continuous, ragged moans. The animals took turns, a rotating relay of brute force. They were tied to the breeding bench where ten of them rammed them deep, over and over, a brutal, living conveyor belt of primal energy.

By the fifth, Jake’s mind had detached. His body was no longer his. It was a terrain being mapped by a succession of powerful, mindless explorers. The leather straps bit into his skin. The timber frame shook with every driving impact. The air was thick with the smell of sex and hay and animal.

It went on. The eighth stallion was the largest. Its entry was a slow, burning conquest that felt like it reached his spine. The ninth was relentless, a jackhammer of short, hard strokes that stole his breath.

When the tenth finally clomped away, the silence was a physical blow. Jake sagged against the straps, dripping sweat onto the dusty floor. He was profoundly, incomprehensibly full. He felt split open, reconfigured by hooves and heat.

Mara unstrapped them. Her hands were surprisingly gentle. They couldn’t stand. They slid to the packed earth floor, legs useless. Thorne was there instantly, crouching, his scanner humming. But he wasn’t looking at the readout. He was looking at their faces, at their utterly shattered expressions.

“The data…” he breathed, his own hands shaking. “The sympathetic nervous system responses mirrored the equine partner’s. You weren’t just receiving force. You were syncing with it. Becoming part of the biological circuit.”

Leo let out a weak laugh, his face pressed against the cool earth. “So we’re good with horses. Great. Add it to the resume.”

Jake didn’t laugh. He looked up at Thorne, at the barn rafters high above. The hollow feeling was gone. In its place was a deep, resonant ache, a memory of being ten different kinds of full. “What’s next?” he asked again, his voice raw.

Thorne looked from the stallions being led back to their stalls, to his trembling scanner, to the two broken young men on the ground. A new, impossible idea dawned in his eyes, luminous and dark.

“Now,” he said softly, helping Jake to his unsteady feet, “we see what you build.”

Weeks blurred into a numb routine of sore muscles and strange paychecks. The hollow feeling in Jake’s gut wasn’t gone; it had just learned to feed on the aftermath, the deep bone-ache that followed each session. Leo’s jokes grew darker, thinner. Thorne stopped sleeping altogether, moving through the converted barn like a specter armed with a tablet.

“Build?” Jake had asked that day in the dust, leaning on his friend. “What’s left to build?”

The answer came on a morning thick with the smell of impending rain. Two new stallions stood in the stocks. They weren’t just large. They were monolithic, their shoulders like boulders, their haunches power itself carved from living rock. They made the previous animals look like ponies.

“Holy fuck,” Leo breathed, all sarcasm drained.

Mara shook her head, running a hand over a neck thicker than her torso. “Clydesdale crosses. Bred for pure pulling power. Gentle as lambs. But when they’re engaged...” She let the word hang.

Thorne was already at the modified timber frame. It was no longer a breeding bench. It was a structure of reinforced beams and heavy-duty pulleys. “The previous sessions explored horizontal force transfer,” he said, his voice clinical, but his eyes were alight. “Vertical force, combined with gravitational assistance, presents a new vector. The depth achievable… it recalibrates everything.”

Jake understood. He looked at the hoisting apparatus, the heavy leather harnesses dangling. They weren’t going to be leaning over. They were going to be suspended. Open. Helpless to gravity’s pull.

The preparation was silent. The gel was cold. The harnesses were thick, clammy, and smelled of old sweat and oil. They were fitted around their thighs and torsos, leaving them exposed. The feeling of being lifted off the ground, of the straps taking his full weight, sent a primal jolt through Jake. He dangled, a few feet above the packed earth, spinning slightly.

Leo, hanging beside him, let out a shaky laugh. “Feels like we’re about to be lowered into a volcano.”

The first behemoth was led out. The stallion’s sheer mass seemed to dim the light. Mara guided it not to a chute, but directly underneath them. She fitted Thorne’s custom interface—a ridged, synthetic sheath that gleamed under the barn lights. The stallion snorted, stomping a heavy hoof.

Thorne, from his console, didn’t give a warning. He just activated the winch.

Jake descended slowly, inexorably. The world narrowed to the sight below: the immense, shifting animal, and the rigid, patient presence aimed upward. He was being lowered onto it. The perspective was all wrong. He was a peg seeking a hole, guided by nothing but the slow, mechanical groan of the pulley.

The initial contact was a hot, blunt pressure. Then gravity took over. His own weight, guided by the harness, drove him down. There was no push from below. There was only yielding. The stallion’s instinctual upward shift was a minor adjustment to the crushing, downward force of Jake’s body.

The stretch was instantaneous, vast, and shocking. It wasn’t a thrust. It was a slow, sinking impalement. The animal’s size was not just girth, but a profound, invading length that gravity ruthlessly exploited. It went deeper than the machines, deeper than the other horses. It reached a place that had no name, a silent, internal scream of space being unwillingly created.

He heard his own voice, a high, ragged sound, tear from his throat. Beside him, Leo was choking, suspended above his own massive partner.

Then the stallion moved.

It wasn’t the rhythmic, full-body drive of before. Suspended, Jake was a fixed point. The motion came from below, a powerful, rolling upward grind of haunches and spine. The force was redirected, concentrated. It pushed up into the relentless downward pull of gravity.

He was being stretched between two immovable forces: the earth’s pull and the animal’s drive.

The rhythm started. It was slow, deliberate, and unbearably deep. Each upward surge lifted Jake’s entire suspended body, the harness biting into his flesh. Each slight drop allowed gravity to drag him further down the rigid length. He wasn’t being fucked. He was being mined.

Time dissolved into the creak of the pulley, the snort of the beast, and the raw, open-mouthed gasps he could no longer control. The stallion’s rhythm was patient, relentless. It wasn’t trying to finish. It was just being, a geologic force.

The release, when it came, was a hot, surging flood directly into that newly opened depth. It wasn’t a spurt. It was an infusion, a hot, liquid weight filling a cavity never meant to hold it. Jake felt it, a deep internal warmth spreading, pushing at the edges of his stomach.

The winch reversed, lifting him off with a wet, sucking sound that echoed in the barn. He swayed in the harness, feeling swollen, heavy, irrevocably changed. He watched, dazed, as Mara led the dazed stallion away and brought the second one under Leo.

The process repeated. And repeated.

They lost count of the shifts, the trades. The same two colossal animals, rested briefly, then brought back under their suspended, spent bodies. Each time, Jake was lowered onto a fresh, rigid presence. Each time, gravity pulled him deeper onto a heat that felt ancient. Each time, the animal’s patient, grinding rhythm filled him with a hot, liquid mass.

His stomach cramped, a dull, protesting ache. It was full. He was being packed.

During the fourth or fifth rotation, as another pulse of heat flooded into him, the cramp twisted sharply. A sour taste flooded his mouth. His body convulsed, not in pleasure, but in visceral, biological rejection. He turned his head and a hot, sour stream of pale fluid vomited from his lips, spattering the dusty ground far below. It wasn’t just bile.

Leo saw. His eyes, wide with a kind of horrified understanding, met Jake’s. A minute later, suspended above his own stallion, Leo’s body jerked. A similar, choked cascade spilled from his mouth, dripping onto the animal’s back below.

Thorne’s voice crackled over the speaker, devoid of horror, filled with a terrible wonder. “Note the somatic rejection. Capacity is being exceeded. The body is attempting to purge the excess. Fascinating.”

On the next rotation, under the strain of Leo’s weight and the stallion’s powerful upward drive, a leather strap on his harness gave way. It didn’t snap cleanly. It tore with a sickening ripping sound.

Leo dropped.

He didn’t fall far—maybe two feet—but it was enough. He landed awkwardly, partly on the stallion’s back, partly off, one leg still caught in the dangling harness. The animal, startled, sidestepped. Leo hit the hard-packed earth on his side, the wind knocked out of him.

But the stallion was bred, prepped, and engaged.

It didn’t stop. It turned, confused by the sudden shift, but the rigid, instinctual drive remained. It mounted him where he lay.

There was no harness. There was no controlled descent. There was only Leo, prone on the ground, and a thousand pounds of determined animal above him.

A raw, terrified scream tore from Leo’s throat as the stallion found its target. This was not the deep, grinding submission of the harness. This was a violent, chaotic pounding. The animal’s hooves dug into the earth on either side of Leo’s torso. Its full weight drove downward, pinning him to the dirt. Each thrust was a brutal, compact slam, driving Leo’s body into the unyielding ground.

“Stop!” Jake screamed, useless, swinging in his harness. “Thorne! Stop it!”

Thorne was already moving. He vaulted over the console railing, not bothering with the stairs, landing in a crouch on the barn floor. He didn’t try to pull the animal off. That was impossible.

He ran to Leo’s head.

Leo’s screams had become choked, desperate sobs as the pounding continued, each impact jarring his spine, crushing the air from his lungs. His hands scrabbled weakly at the dirt.

Thorne dropped to his knees. He grabbed Leo under the shoulders, his own muscles straining. He didn’t pull him out. He held him. He anchored him, using his own body as a counterweight against the driving force, preventing Leo from being pummeled completely into the earth. He locked eyes with Leo, his face a mask of fierce, desperate intensity, holding his head and shoulders firm as the stallion raged above them.

Jake watched, suspended, a fly in amber. He watched his best friend being pounded into the ground. He watched the man who had done this to them holding him through it, a perverse guardian against the very violence he had orchestrated.

The stallion finished, dismounted, and clopped away, calm now.

Silence rushed in, broken only by Leo’s wet, ragged coughing and Thorne’s labored breathing as he crouched over him. Mara stood frozen by the stocks, her hand over her mouth.

Thorne looked up from Leo’s broken form, his gaze finding Jake’s across the barn. There was no apology in his eyes. No horror. Only a blazing, insatiable hunger for the data point he had just witnessed.
