Chapter 13: Mechanical Rutting
The silence after Thane’s withdrawal was a physical presence, thick with the reek of spent cum, sweat, and Sera’s own terror. Her throat felt like shredded meat, each ragged inhalation scraping raw nerves. The halo pressed its cold steel imprint into her forehead, the leather straps binding her body a familiar cage. Eleven. The number echoed dully, a death knell. Eleven brutal, electric-shock induced peaks wrung from her violated throat, leaving her hollowed out, trembling uncontrollably. The hollow ache deep in her pelvis where the plug had ceased its torment was a mockery of relief; it was merely biding its time.
Thane’s polished shoes appeared in her limited view again. He crouched, a predator assessing wounded prey. His cool fingers traced the tear tracks on her cheek, then gripped the release mechanism of the steel halo. With a soft clunk, the pressure vanished from her skull. Before she could even register the freedom, large hands were at her shoulders, unbuckling straps with swift, clinical efficiency. The restraint across her shoulder blades loosened, then the ones pinning her arms and biceps. He worked his way down, freeing her torso, then her legs. Sera slumped forward as the last ankle restraint released, her limbs heavy and uncoordinated, muscles screaming from the prolonged tension and violent convulsions. She barely caught herself on the cold floor, her palms flat, head hanging, gasping.
"Up, Blake." Thane’s voice was devoid of warmth. He didn’t offer a hand. "Studio 3. Now."
She pushed herself upright, swaying, the world tilting slightly. The chastity belt, a constant, rigid weight low on her hips, felt heavier than ever. Her abused throat burned. She shuffled, every step sending dull echoes of pain through her legs, towards a plain, unmarked door Thane indicated with a tilt of his head. Allen watched her pass, that faint, knowing smirk still playing on his lips.
Studio 3 was a stark contrast to the Oral Mastery Chamber’s clinical semi-circle. Smaller, utterly minimalist. Bare white walls, no furniture save for a single, sturdy desk positioned dead center under the soft, indirect lighting. On the desk sat one object: a dildo. It wasn't sleek metal like the others. This one was flesh-toned silicone, uncannily life-like, thickly veined, crowned with a broad, pronounced head. Sera recognized it instantly – a perfect replica of Dominick’s cock. The sight sent a complex jolt through her exhausted system: a pang of longing, a twist of humiliation, a fresh spike of fear.
Thane closed the door, the soft click echoing in the sterile quiet. He moved behind her. She flinched as his hands grasped her shoulders, turning her to face the desk and the replica. "Hands behind your back," he commanded.
She obeyed, crossing her wrists at the small of her back. The cold, heavy click of magnetic cuffs snapped shut around them, binding her arms securely. The position thrust her chest forward, making her raw nipples brush against the cool surface of the desk as she stood close to it.
"Dominick expects proficiency," Thane stated, his deep voice resonating close to her ear. He removed the small imitation, leaving room for what was before her. "He desires his cock taken deep, hard, and without hesitation. You failed at the throat. You will not fail at the cunt." His hand pressed firmly between her shoulder blades, forcing her torso down over the desk. Her bound arms pressed uncomfortably into her lower back. He guided her hips back, positioning her ass high, her cunt presented directly over the waiting replica. The cool air of the room kissed her exposed labia.
He didn't bother with lube. His fingers, impersonal and efficient, delved between her thighs, finding her slit. She was already wet – a traitorous slickness born from the relentless overstimulation, the terror, the sheer biological response forced upon her. Thane spread her lips, exposing her sensitive folds, and positioned the broad silicone head directly against her entrance. It felt huge, intimidating, especially after the ravaging her throat had endured.
"You will impale yourself," Thane instructed, his tone icy calm. He activated a small controller in his hand. The chastity belt emitted a low, ominous hum. "Every time you slow, every time you hesitate, every time you fail to take it deep enough..." He paused, letting the threat sink in. "...this plug will remind you of your duty. It will shock you until you comply. Until you achieve orgasm. Three times."
He tapped his tablet, mounted on a stand nearby. The biometric readout flickered to life on the wall opposite, mirroring her vital signs. Her heart rate, already elevated, jumped. Her respiration hitched. "Begin."
Sera took a shuddering breath. She had to do this. The alternative – the plug reactivating – was unthinkable agony. She pushed her hips back, trying to sink down onto the thick silicone head. It resisted, the broad tip stretching her tight entrance painfully. She whimpered, pausing for a fraction of a second.
ZZZAP!
The shock was instant and blinding. Not the deep, punishing thrum from before, but a sharp, searing jolt directly into her clit, courtesy of the chastity belt's integrated electrodes. It was like being branded. Sera screamed, her body jerking violently against the desk, her bound wrists straining against the magnetic cuffs.
"Faster. Deeper," Thane commanded, unmoved. He leaned against the wall, observing the biometric screen, his expression detached. "Don't make me motivate you again."
Terror overriding the residual pain, Sera shoved herself down hard. The thick head finally breached her, stretching her inner walls wide with a burning ache. She cried out, the sound raw. She forced herself lower, taking more of the unforgiving length. The replica's textured veins scraped roughly against her sensitive inner flesh with each inch she descended. It was too much, too soon, too rough after everything. She faltered, her thighs trembling.
ZZZAP! Another vicious shock, stronger this time. Her vision blurred. Her muscles spasmed, forcing her down further onto the dildo in a convulsive jerk. A wet, obscene squelch echoed in the small room as she bottomed out, the replica buried to the hilt inside her. The textured veins ground against her cervix.
"Good," Thane murmured. He tapped his tablet. "Maintain rhythm. Ride it. Hard and fast. Like Dominick demands." He pressed another control. A small, high-definition recorder on the desk whirred to life, its red light blinking. "He wants to hear how well you serve, even in his absence. Let him hear what his property sounds like when she’s properly disciplined."
Humiliation burned hotter than the internal scrape. Sera pushed herself up, the silicone dragging brutally against her raw inner walls. The sensation was a sharp counterpoint to the lingering buzz of the shock. She paused at the apex, dreading the descent.
ZZZAP! The shock punished her hesitation instantly, forcing her back down with a choked sob. The dildo slammed home, the impact vibrating through her pelvis. Squelch. The recorder captured it perfectly.
Up. Drag. Scrape. Pain. Fear. Down. ZZZAP! Slam. Squelch. The rhythm became a desperate, punishing loop. Her body moved like an automaton, driven by the threat of electricity. Every upward movement was agony as the textured veins scraped her sensitive, overstimulated tissues. Every descent was a brutal invasion, ending in that humiliating wet sound amplified by the recorder. Sweat poured down her spine, stinging the scrapes on her back. Her bound arms ached. Tears streamed down her face, dripping onto the cool desk surface.
The biometric screen showed chaos. Heart rate erratic, soaring with each shock and descent. Respiration shallow and rapid. The arousal graph, however, was climbing again, relentlessly. The denial, the forced stimulation, the sheer relentless violation – her body couldn't differentiate. It responded. Heat pooled low in her belly, a treacherous warmth beneath the pain and fear. Her inner muscles, involuntarily, began to flutter around the thick intrusion with each brutal thrust downward.
"Feel it, don't you, slut?" Thane observed, his voice low and hypnotic despite its chill. He didn't move from his post by the wall. "That filthy cunt, getting wetter, tighter? Even while it's being torn up? That's your body admitting what it is. What you are. A hole made to be used. Hard." ZZZAP! He shocked her again, not because she faltered this time, but seemingly just to punctuate his point, to make her clench and scream. "Cum for it. Cum on Dominick's cock. Show him how well his property obeys."
Sera was losing herself in the cycle of torture and unwanted response. The shocks blurred with the internal scraping, the humiliation of the recorder capturing every wet slap and desperate whimper. The heat intensified, coiling tighter despite the pain, despite her mind screaming no. The flutters became stronger, involuntary contractions gripping the textured silicone. She was riding the edge, the line between agony and ecstasy obliterated by the relentless conditioning.
"Twelve, Blake," Thane stated flatly, watching the screen where her pelvic muscle contractions spiked off the chart. "Give it to us."
He pressed the shock button and held it down.
ZZZZZZZZZZZZZZZZZAP!
A continuous, searing current ripped through her clit, up into her cunt, merging with the brutal fullness of the dildo. Sera’s back arched impossibly, a silent scream tearing from her ruined throat. Her body locked, rigid, every muscle seizing. The coil snapped. Orgasm detonated through her, a violent, convulsive tsunami of sensation that was indistinguishable from the electric torture triggering it. It tore through her like shrapnel, raw and agonizing, wringing a guttural, shattered moan from her chest as her cunt spasmed violently around the thick replica. Squelch-squelch-SQUELCH. The recorder captured the obscene symphony of her forced climax. The biometric screen went haywire, vital signs peaking, the arousal graph a single, solid red line.
The shock ceased. Sera collapsed forward over the desk, boneless, gasping like a landed fish, her limbs trembling violently. The dildo remained buried deep inside her, a constant, throbbing reminder. Sweat plastered her hair to her face and neck. Cum – not hers, just the slick evidence of her violation – trickled down her inner thighs. The recorder’s red light continued to blink, a silent, judging eye.
Thane stepped forward. He didn’t deactivate the plug. He didn’t turn off the recorder. He placed a large, cold hand on the small of her back, right above the magnetic cuffs. The touch was devoid of comfort, purely possessive.
"Two more," he rumbled, his voice a low promise of further ruin. His thumb traced the curve of her ass, a chilling caress. "Dominick expects a complete set. Let's make this cunt worthy of him." He tightened his grip, forcing her hips to shift slightly, grinding the textured replica deeper into her ravaged, oversensitive core. The movement sent fresh jolts of pain-tinged sensation radiating outwards. "Begin."
The word hung like a guillotine. Begin. Sera’s exhausted muscles screamed, her cunt still pulsing with the brutal aftershocks of the twelfth orgasm Thane had ripped from her. Her thighs trembled violently as she tried to lift herself off the thick silicone replica. The textured veins dragged against her raw inner walls, a fresh wave of agony making her gasp. She managed a few inches upward, a pathetic whimper escaping her battered throat. The descent was worse. She braced, but her body refused the brutal re-entry smoothly. She dropped too fast, too shallow, the broad head slamming against her entrance rather than sinking deep. Thud. Not the deep, wet squelch Thane demanded.
"Pathetic," Thane hissed, his voice cutting through the sound of her ragged breathing. The shock hit before she could even register her failure. ZZZAP! Electricity sizzled through her clit, sharp and vicious. Sera convulsed, a strangled cry tearing loose as the pain jolted her spine straight. The involuntary spasm forced her down hard onto the dildo. It buried itself deep, the textured ridges scraping mercilessly against her cervix. Squelch. The recorder captured the wet, ugly sound. "That depth was barely adequate," Thane growled. "Do it again. Properly. Or I will make the next correction memorable."
She pushed up again, sweat stinging her eyes. Her arms ached where the magnetic cuffs bit into her wrists. Down she went, forcing herself this time, focusing through the haze of pain and exhaustion. The head stretched her, burned her, but slid deeper. Almost enough. She hit bottom, the silicone base pressing hard against her pubic bone. Squelch. A weak sound. Thane watched the biometric screen, his expression impassive. "Marginally better. Now, faster. Dominick doesn't have time for your lazy fucking."
Sera tried. God, she tried. She pushed her hips back, lifted, dropped. Lift. Drop. But her strength was failing. The rhythm stuttered. She managed two, maybe three, decent strokes – deep enough to pull a wet sound from her abused cunt each time she bottomed out. Then her thighs quivered violently, threatening to buckle. The next descent was hesitant, shallow. The silicone head barely penetrated an inch before her body locked up, trembling. "No... please..." she rasped, knowing what came next.
Thane moved. Not towards the shock controller. Fast, terrifyingly silent, he was suddenly behind her. His large, cool hands clamped onto her hips like steel vices. "You cannot even fuck a piece of plastic without assistance, you useless hole?" His voice dripped with contempt. His grip tightened, fingers digging into the soft flesh above her hip bones, his thumbs pressing hard into the small of her back. He didn’t give her a chance. He yanked her upwards, pulling her halfway off the dildo with brutal force. Her inner walls screamed in protest at the sudden, harsh withdrawal. "Deep!" he snarled.
Then he slammed her down. Hard.
THUD-SQUELCH. Her entire body jolted. The replica plunged to the hilt in one violent stroke, the impact shuddering through her pelvis, the textured veins scraping like coarse sandpaper. The air exploded from her lungs in a pained sob. Before she could even process the shock, Thane hauled her back up, almost lifting her off the desk, then hammered her down again. THUD-SQUELCH. And again. THUD-SQUELCH. There was no rhythm she could control, no chance to brace. He used her body like a flesh-and-bone piston, fucking her ruthlessly onto the silicone cock. His strength was terrifying, absolute. Each downward slam forced the air from her lungs, each brutal descent stretched her burning entrance, each jarring impact ground the textured shaft against her raw, sensitive cervix.
"Feel that, cunt?" Thane grunted, his breath hot against her ear as he drove her down once more, his hips pressed flush against her ass for leverage. His cock, rigid even through his trousers, pressed into the cleft of her ass. "That's how deep you take it. That's the pace you keep." THUD-SQUELCH. She gagged, tears streaming freely, her vision blurring. The sensations were a horrifying blur – the tearing scrape inside, the bruising grip on her hips, the hard edge of the desk biting into her lower belly, the relentless THUD-SQUELCH of her body being used. Her own arousal, a traitorous slickness forced from her by the overwhelming stimulus, only made the obscene sounds louder for the recorder.
"Your fucking cunt's dripping, Blake," Thane observed coldly, never slowing the brutal pace. He pulled her up, then slammed her down so hard the desk legs scraped on the floor. "Look at the screen. See how your body betrays you?" The biometric display flickered wildly. Heart rate spiking into dangerous territory. Respiration erratic. But the arousal line? It wasn't just climbing; it was surging, peaking again in jagged spikes that coincided with each punishing downward thrust. Her own body, under this assault, was coiling tighter, hotter, the flutters around the thick intrusion becoming frantic clenches. "That's it, you dumb cunt," Thane rasped, grinding her hips down in a vicious circle after a particularly hard slam, the silicone head grinding into her deepest spot. "Cum again. Cum while I fuck you like the broken toy you are."
He slammed her down. Held her there, grinding. The pressure, the scrape, the overwhelming violation, the sheer physical force holding her captive – the coil snapped. A raw, ragged scream tore from Sera's throat as her body convulsed, her cunt clamping down in violent, involuntary spasms around the thick silicone shaft buried deep inside her. It was less pleasure, more a catastrophic system failure, an agonizing wave of sensation that ripped through her like a physical blow. SQUELCH-SQUELCH-SQUELCH. The recorder captured the wet, rhythmic clenching perfectly. Thane kept her pinned, grinding lightly, prolonging the brutal pulses as the thirteenth orgasm wracked her shattered frame. He leaned closer, his lips brushing her sweat-slicked ear. "Thirteen. One more, then your final session. Let's see how much this greedy hole can take it." His hands tightened, ready to piston her again.
Thane’s grip on her hips tightened like a vise, fingers digging into the bruised flesh as he resumed the brutal, mechanical rhythm. He hauled her back, suspending her trembling body half off the fake cock, her stretched cunt gaping obscenely for a split second. Then he slammed her down with piston-force, driving the thick silicone shaft deep into her ravaged core. Thud-squelch. The impact jarred her teeth. He did it again. Thud-squelch. And again. Thud-squelch. Each descent was a controlled collision, grinding the textured veins against her raw cervix, forcing ragged, punched-out gasps from her throat.
"Pathetic," he grunted, his voice tight with exertion and disdain. Sweat beaded on his forehead as he worked her body, his own arousal evident against her ass. "Can't even fuck properly without being handled. Worthless hole." His rhythm didn't falter; up with a brutal jerk, down with crushing force. The recorder captured every wet, brutal sound her body made. Her exhausted cunt, slick with forced arousal and her own earlier release, offered little resistance, only burning pain and the awful, scraping fullness. Tears blurred her vision, dripping onto the cool desk.
His left hand suddenly released her hip. It snaked around her trembling torso, fingers splayed, seeking. They found the mottled, deep red flesh of her left nipple, still raw from the Oral Chamber's restraints. He didn't stroke. He didn't tease. His thumb and forefinger closed like pliers, pinching the swollen, hypersensitive bud with cruel precision. Hard.
Sera shrieked, a sound ripped from her very core, arching violently against the violation. The sharp, electric agony from her nipple fused with the deep, grinding ache of the dildo hammering her cervix. "N-no! God, please don't!" she sobbed, her body convulsing in his iron grip. The shock was immediate, overwhelming. Her bound arms strained uselessly against the magnetic cuffs. Thane didn't relent. He squeezed harder, twisting the tender flesh, the brutal pinch a counterpoint to the relentless pistoning of her hips. He used the leverage to yank her down onto the dildo with even more force on the next thrust. THUD-SQUELCH.
"Shut your fucking mouth," Thane growled against her ear, his breath hot and harsh. His fingers kept their brutal grip, twisting her nipple, amplifying the sensory storm. "This is your purpose. Take it. Cum on it." He slammed her down again, grinding the base of the fake cock against her clit while his fingers tormented her breast. The dual assault was intolerable. Pain and unwanted, traitorous pleasure collided in her shattered nerves. The biometric screen flashed crimson warnings – heart rate critical, respiration gasping – but the arousal line spiked violently off the chart. Her cunt, despite the agony, fluttered and clenched desperately around the thick intrusion. Betrayal. Humiliation. Overload.
He felt it. The frantic, involuntary spasms gripping the silicone. He intensified everything. His hand on her hip slammed her down harder, faster. His fingers twisted her nipple viciously, pinching until she saw white spots. "NOW, SLUT!" he roared. "CUM!"
It detonated. Not pleasure, but annihilation. A raw, seizing convulsion tore through her, fueled by agony and violation, ripping a strangled, inhuman sound from her torn throat. Her body locked rigid, spine arched impossibly, every muscle seizing. Her cunt clamped down in violent, rhythmic spasms, milking the textured dildo buried deep inside her. Squelch-squelch-SQUELCH. The recorder captured the obscene wet clenching perfectly. Thane held her down, grinding relentlessly, his fingers still cruelly twisting her nipple, prolonging the brutal pulses of her fourteenth forced orgasm. It felt like being flayed alive from the inside, a wave of sensation that obliterated thought, leaving only shattered ruin.
Slowly, the convulsions subsided into violent tremors. Thane finally released his cruel grip on her nipple, leaving the swollen bud throbbing and bruised. He stopped pistoning her hips. Sera collapsed forward over the desk, utterly spent, her breath coming in ragged, wet sobs. Spit and tears pooled under her cheek. The fake cock remained lodged deep inside her, a constant, throbbing ache. Sweat soaked her hair, plastering it to her scalp and neck. The chastity plug hummed faintly, a silent threat. The recorder’s red light blinked, unblinking.
Thane stepped back. He surveyed her wrecked form, the chaotic biometrics slowly settling, the arousal line still registering high despite the collapse. He wiped his hand casually on his trousers. "Fourteen," he stated, his voice coldly clinical again. "Acceptable." He tapped his tablet, silencing the recorder. The red light died. He didn’t deactivate the plug inside her. "Recovery period. Ten minutes." He walked towards the door, pausing only to glance back. "Then, Blake, your final session." The door clicked shut behind him, leaving her impaled, trembling, and utterly alone with the hollow dread of what was still to come.
