Chapter 31: Metal Invasion
The afterglow of the Orgasm Amplifier was a ghost in her nerves, a persistent hum beneath her skin. Maggie lay spent on the rumpled silk, her body still twitching occasionally, her holes feeling used and deliciously loose. Ben was already at his workstation, fingers flying across a tablet, his face lit by the blue glow. “Feedback from the last stream was… instructive,” he said, not looking up. “They loved the convulsions. The count. But they’re hungry for architecture. For form.”
Maggie pushed her fiery hair from her sweat-damp forehead. “Architecture?”
“A spectacle of engineering,” Ben said, finally turning to her. His eyes were bright, that quirky fascination focused into a sharp point. “Not just random shocks. A synchronized event. Growth against stretch. A symphony of forced opening.” He gestured to a new case by the bed, sleek and gunmetal grey. “I call it the Hydraulic Spreader.”
He helped her up, his hands clinical yet possessive on her waist. She was unsteady, her thighs slick, the memory of the plug’s removal a dull, full ache in her ass. “Tonight,” he murmured into her ear, his breath cool, “we build the masterpiece. We’re going to hang you.”
He led her to the center of the room where a heavy-duty rig was suspended from a ceiling beam she’d never noticed before. It was a harness of reinforced black straps. “Arms up,” he said, and she complied, a shiver of anticipation cutting through her fatigue. He secured the harness around her torso and thighs, the straps crossing between her breasts and biting into the soft flesh of her inner thighs. With a soft whirr of a motor, he activated the winch.
Maggie gasped as her feet left the floor. The harness took her weight expertly, suspending her in a perfect ‘flying frog’ position. Her knees were bent, pulled wide apart by the straps, her body leaning forward. Her full, heavy tits swayed freely beneath her, nipples pebbled tight from the cool air and the exposure. Her pussy and ass were presented utterly, vulnerably. And her clit, already prominent and sensitized from a year of dedicated play, hung down like a thick, ruddy shaft between her labia.
Ben adjusted the camera’s angle, its lens focusing on her suspended form with intimate clarity. “Welcome back, folks,” he said to the feed, his voice a steady, technical murmur. “We’re exploring synchronous feedback loops tonight. The subject’s arousal state will directly dictate the mechanical parameters.”
He approached Maggie, holding a black silicone gag and a pair of molded earplugs. She opened her mouth for the gag without hesitation, a conditioned reflex that sent a warm pulse through her cunt. He fitted it snugly, the strap tight behind her head, then inserted the plugs, sealing her in a silent world of her own heartbeat and breath. Her wide, green eyes watched him, trusting and hungry.
“Subject is now sensory-restricted to tactile and visual stimulus only,” Ben narrated, his fingers trailing down her belly. “Her awareness will be purely physical. No external sound. No words.” He traced the length of her dangling clit, already a formidable eight inches of hypersensitive flesh. She bucked slightly in the harness at the contact, a muffled moan escaping the gag.
From the case, he retrieved the milker sleeve. It was a transparent cylinder of medical-grade silicone, lined with intricate, rhythmic pulsators. He coated her full length with cool, conductive lube, making her twitch. “Initial attachment,” he said, sliding the sleeve over her until it sealed at the base with a soft hiss. A soft suction engaged immediately, pulling her clit taut within its tube, making the swollen head flare against the clear ceiling of the device.
He gave the encased shaft a few casual, almost disrespectful slaps. The thwack-thwack sound was absorbed by her earplugs, but the vibration travelled straight to her core. Her pussy drooled a fresh strand of slickness that gleamed in the camera light. “Priming the tissue,” Ben commented. “Encouraging vascular compliance.”
Next, he lifted a device that looked like a multi-barreled syringe gun. Four slender needles surrounded a central reservoir bulb filled with a viscous, pearlescent fluid. “The expansion serum,” he explained to the chat. “A proprietary saline and collagen hybrid. We’ll inject dorsally, laterally, and into the glans. The subject’s own arousal will accelerate dispersal.”
He pressed the needle array against the trapped flesh of her clit, finding spaces between the pulsators. Maggie flinched at the first sharp pinch. Ben depressed the plunger slowly. The fluid entered her in four distinct, cold streams. For a moment, nothing changed.
Then a deep, internal pressure began to build. It wasn't pain, but a profound, stretching fullness, as if her most sensitive part was being inflated from the inside. Her muffled cries became rhythmic, desperate pants against the gag. Her clit began to thicken, the skin growing taut and shiny within its transparent prison. It swelled past its previous girth, filling the milker sleeve until the pulsators had to work harder, grinding against the expanding flesh.
Ben watched the metrics on his tablet. “Vasodilation is exceeding projections. Good.” He injected another slow bulb of serum. Her clit, now as fat around as his clenched fist, began to lengthen. It pushed against the end of the milker sleeve, the flushed, purple-red head distending the silicone cap. The sleeve’s automatic mechanism whirred, extending itself to accommodate the new growth.
Maggie’s eyes were screwed shut, her entire universe the relentless, pumping throb of her own transformation. When she forced them open, tears of overwhelming sensation streaking her cheeks, she looked down. What she saw between her swaying tits wasn’t her familiar clit. It was a monstrous, veined cock of her own flesh, twelve inches of rigid, alien weight trapped and throbbing in the machine. A choked scream of shock and impossible arousal caught in her gag.
“Observe the subject’s realization,” Ben said coolly. “The cognitive dissonance. The feed is spiking.” As he spoke, he retrieved the second device from the case. The pronged stretcher was a cruel, beautiful thing of polished steel. Four curved blades met in a tapered point, smooth and cold. He lubricated them thoroughly, the gel dripping onto the floor.
He positioned the tip against her asshole, that grudgeful, swollen rosette still tender from the previous session. With steady, relentless pressure, he began to work the closed prongs into her. Maggie’s body resisted, her hole clenching tight, a tight star of denial. Ben pushed until the tip breached her, and her sphincter was forced to hug the converging steel.
A high-pitched whine escaped her. On his tablet, a graph spiked. “There’s the feedback,” he murmured. “Physiological arousal is climbing. And so…”
He tapped a command. With a minute hydraulic whisper, the prongs inside her began to separate. It was a millimeter of movement, a barely perceptible stretch. But inside her, it was an epoch of opening. Her body jerked. The graph spiked higher. The milker sleeve intensified its rhythm, pounding her newly massive clit. The prongs responded, parting another millimeter.
Her cunt was a waterfall, her juices painting her inner thighs. Every fractional stretch of her ass sent a blistering wave of heat through her pelvis, which the sensors read, which fed the machines, which stretched her more. It was a perfect, hellish circuit. Her clit felt like a lightning rod, every pulse from the sleeve shooting volts into her overwhelmed brain. She was trapped in the feedback loop, her own arousal literally prying her open.
The loop was a living thing, a snake eating its own tail made of sensation and steel. Ben watched the data waterfall on his tablet, a satisfied smirk touching his lips. "Threshold achieved," he announced to the unseen audience. "Primary systems locked. Manual override engaged for phase two."
He stepped close, the heat of her radiating body hitting him first. Her huge clit, now a grotesque and gleaming pillar of flesh, strained against the pulsating sleeve. He disconnected the automated rhythm. "Let's get hands-on, folks." He wrapped his fist around the silicone cylinder, feeling the hard, throbbing meat within. He began to jerk it, a slow, deliberate up-and-down motion that mimicked a brutal handjob.
The sensation was catastrophic. After the machine's precise tempo, this animal roughness was a shock. Maggie bucked violently in the harness, the straps creaking. Her monstrous clit swayed with the motion, a pendulum of tortured nerve endings. A true clitslut, she moaned, a raw, guttural sound that vibrated through the gag, all protest dissolved into base acceptance.
"See that?" Ben said, his voice bright with fascination. "Total neurological submission. The ego is gone. All that's left is the function." He increased his pace, his hand a blur on the sleeve, the friction inside translating into a brutal, delicious grind. Her juices, which had been dripping, now flowed in a steady stream from her cunt, pattering onto the floorboards.
He shifted his focus. The steel prongs in her ass were parted to a width of three fingers, her rim a stretched, shining ring of pink muscle pulled taut around the cold metal. He raised his other hand, calloused palm open. "Let's test structural integrity." He brought his hand down in a sharp, crisp spank directly onto the straining rim of her anus.
The slap cracked through the room. Maggie’s entire body seized, a wire pulled tight. The impact sent a seismic shock through her pelvis, a vibration that rang through the stretched channel and into her swollen clit. It wasn't pain alone; it was a brilliant, white-hot fusion of violation and pleasure that short-circuited her thoughts.
"Fuck yes," Ben breathed, watching the data spike. He did it again. Spank. The metal prongs hummed inside her. Spank. Her cunt, which had been flowing, suddenly clenched and spat. A thick rope of clear fluid shot from her, not a drip but an actual spurt, arcing through the air to join the mess on the floor.
"Eu-re-ka," he enunciated, laughing softly. "Direct somatic feedback. Hit the hole, squeezes the cunt." He alternated now, a relentless rhythm: three brutal jerks of the sleeve, then a stinging spank to her glistening, stretched hole. Each impact made her squirt, her body betraying her utterly, translating the sharp sting into a gushing, humiliating release.
Maggie was gone, lost in a storm of sensation where every boundary between pleasure and pain, between her ass and her clit and her cunt, had melted into a single, scorching brand. Her world was the grip on her flesh, the crack on her rim, the hot flood leaving her. Her moans were constant now, a low, unwavering drone of surrender.
Ben’s narration turned intimate, conversational. "You see, the Orgasm Amplifier was about volume. Quantity. This is about quality. Architecture." He spanked her again, harder. "We're building a monument. And every brick is a shockwave." Her following spurt was weaker, a dilute trickle. She was emptying, reaching a dry, shuddering edge.
He released the sleeve, the sudden absence of friction its own agony. He traced the swollen, weeping head of her clit through the silicone. "She's hovering. Let's see if we can make the foundation crumble." He placed his thumb against her devastated asshole, right where the steel met trembling flesh, and pressed inward, adding a terrible, pinpoint pressure to the stretch.
Her eyes, unfocused and wet, snapped wide open. A final, broken sound was torn from her. Inside the sleeve, her massive clit gave a series of hard, rhythmic pulses, not an orgasm but a seizure, a last, futile clenching of a muscle pushed beyond all limits. A thin, clear fluid, different from her juices, seeped from the tip. Ben watched it, then the flatlining sensor on his tablet.
"Endurance test concluded," he said softly, almost to himself. He began the slow, careful process of retracting the prongs, the release itself a new kind of torment. The winch lowered her spent body, a marionette with cut strings, into his waiting arms.
The winch lowered her spent body, a marionette with cut strings, into his waiting arms. He caught her with an ease that spoke of practice, her head lolling against his shoulder, her breath hot and ragged through the gag. For a long moment, he just held her there, feeling the violent tremors that still racked her frame, the aftershocks of the machine’s architecture. Then, with methodical care, he removed the earplugs and unsnapped the gag, letting it fall to the sheets with a soft wet sound.
Her first breath was a shattered gasp. “I felt… I felt it building me,” she slurred, her words thick and clumsy. “Like I was made of clay.”
“You were,” Ben said, his voice devoid of its earlier clinical tone, now just warm and close. He laid her on the bed, the silk cool against her feverish skin. “And we’re not letting the sculpture sag.” From the bedside drawer, he retrieved a simple, heavy ring of black silicone. He held it up, pinching it open. “This stays on. No shrinking back. Not after the work we just did.”
Maggie’s gaze, cloudy and spent, focused on the ring. A weak, fascinated smile touched her swollen lips. She spread her trembling thighs wider in silent invitation. Ben gripped the base of her monstrous, saliva-slick clit, which still pulsed with a low, persistent throb. The flesh was hot and impossibly full, a fat, alien crown. He worked the ring down its length, a tight, constricting journey, until it was seated firmly at the very root, squeezing like a second, punishing sphincter. A fresh, sharp ache bloomed there, a constant reminder.
“There,” he said, giving the trapped shaft a possessive tap. It bobbed, rigid and confined. “Now it stays a proper cock. A fucking prize.”
He leaned back, looking her over. Her asshole was a soft, dark bloom, slack and gleaming. Her cunt lips were puffy and well-used. And her clit stood at permanent, ringed attention. He nodded, satisfied. “Good. Recovery protocol. You need electrolytes.” He handed her a bottle of water with a straw, supporting her head as she drank. The mundane care was as intimate as the brutality.
After a few minutes, color returned to her cheeks. The hollow look in her eyes was replaced by a slow, gathering focus. She stretched, testing her body, wincing at the new, permanent fullness between her legs. “It feels… present,” she said.
“It’s supposed to,” Ben replied, standing up. He walked to his equipment case and pulled out something new: a long, clear dildo made of stiff silicone, with measurement lines etched along its side. It was unnervingly realistic, veined and topped with a broad, helmeted head. “Your throat’s been neglected. We need to bring it up to standard. Can’t have a world-class fuckhole like that pussy paired with an amateur gullet.”
Maggie pushed herself up on her elbows, a spark of that old defiance lighting her green eyes. “I can deepthroat.”
“You can gag on a average dick,” Ben corrected, his tone casually challenging. He lubed the fake cock with a viscous gel that smelled faintly of artificial strawberries. “This is eleven inches. We’re training for the olympics, Mags. No more tentative little bobs. We’re going to map your gag reflex out of existence.”
He knelt on the bed, straddling her hips, the cold, lubed head of the dildo brushing her lower lip. “Open.”
She did, taking the tip in, her tongue flattening against the underside. It was a familiar, comfortable weight. Ben didn’t push. He let her set the early pace, watching her eyes. She took four inches, five, her jaw stretching. Then her throat convulsed, a preemptive hitch. She pulled back, coughing.
“See?” he said, not unkindly. “You’re anticipating. You’re thinking about it. You need to become the hole.” He placed a hand on her sternum. “Breathe out. Slowly. Empty your lungs. Your throat’s just a tunnel. A warm, wet sleeve. Nothing more.”
Maggie nodded, breathing deeply, in through her nose, out through her mouth. She opened again, her gaze locked on his. This time, she took the head deeper, letting it nudge the back of her palate. Her eyes watered instantly.
“Good. Now, when you feel the spasm, don’t pull back. Swallow. Swallow around it. Make your throat eat it.”
She pushed forward, the thick ridge of the glans pressing against her taut tonsils. Her body screamed to rebel. Panic flashed in her eyes. But she swallowed, a dry, convulsive gulp. The muscles clenched, then, miraculously, relaxed just enough for the head to pop through into her esophagus. A thick strand of saliva dripped from her stretched lips.
“Fuck yes,” Ben whispered, his own breath catching. “There it is. The first gate.” He applied gentle, steady pressure. The measured inches disappeared into her mouth. Six. Seven. Her nose was buried in his sparse pubic hair. Her throat made a wet, grumbling sound, a protest from deep inside her body.
Tears streamed down her temples into her red hair. Her hands, which had been limp at her sides, came up to clutch at his thighs, her nails digging in. He felt her throat spasming around the invading length, a frantic, rippling massage. “Swallow, Maggie. Make it yours.”
She tried. A choked, gurgling sound vibrated through the silicone and into his hands. He pushed the last three inches, watching the base of the dildo meet her lips. She had taken it all. Her body was rigid, a bowstring of tension. He held it there, buried in her gullet, for a ten-count he narrated out loud. “Feel it. Memorize this fullness. This is your baseline now.”
He began to pull it out, a slow, slick withdrawal. The sound was obscene, a wet, sucking pop as the head cleared her throat, followed by a gasp of air that was half-sob. She gasped, dragging oxygen in, drool and mucus coating her chin. “Again,” she croaked, her voice raspy and ruined.
He plunged it back in, faster this time. There was less resistance. Her throat, though still tight, had learned the shape. It was a raw, physical programming. In and out. He established a rhythm, not gentle, not brutal, but inexorable. Each thrust went to the hilt, each withdrawal made her gag and drool. The room filled with the sounds of her: wet choking, desperate swallows, ragged breaths in the brief moments of air.
Her hands wandered from his thighs to her own body. One gripped the ring at the base of her imprisoned clit, squeezing it, using the sharp, grounding pain as an anchor. The other slipped between her legs, two fingers spearing into her fucked-out cunt, searching for a feeling to match the violation of her throat. She found it, a deep, resonant throb that echoed the fake cock’s strokes.
Ben watched her fall into the trance of use. Her eyes were glazed, fixed on some middle distance, seeing nothing but the internal sensation of being filled. She was perfect. He shifted his angle, tilting the dildo downward slightly. “Now we go deeper. Past the throat. Into the stomach’s welcome.”
The next thrust aimed lower. The bulbous head pressed against a new, inner ring of muscle. Her body arched off the bed, a silent scream in her eyes. He pushed, using the force of his whole body. There was a yielding, a profound internal pop, and the dildo slid into a deeper, hotter channel. Her stomach bulged slightly under his hand.
“Jesus, you took it,” he breathed, his calm fracturing for a second into pure awe. “You fucking took it all the way.”
He fucked her throat in that new, deep place, short, grinding strokes that made her guts quake. Her fingers worked her cunt furiously, splashing more wetness onto the sheets. The sounds from her were no longer human, just a series of wet gulps and grunts. Her body was a instrument being played to its breaking point, a symphony of orifice and obedience.
After an eternity of this, he pulled the dildo free with a final, slick schlop. She collapsed back, heaving, her throat working furiously on nothing, a gaping, used passage. She turned her head and vomited a small stream of clear fluid and lube onto the silk.
Ben wiped her mouth with the edge of the sheet. “That’s it. That’s the session.” He leaned down, kissing her forehead, his lips salty with her sweat. “Your throat’s a champion now. Just like the rest of you.”
He lay down beside her, gathering her shaking form against him. She nuzzled into his chest, her ruined throat making a soft, wheezing sound with each breath. One of her hands still idly stroked the cock ring, a keepsake from the night’s transformation. The other rested over the slight, tender swell of her stomach.
“Tomorrow,” he said into her hair, his voice already planning, “we connect the systems. We’ll rig the deepthroat sensor to the clit ring. Every gag, every swallow, will make that pretty fucking cock of yours throb. A full-body circuit, Mags. No escape.”
Maggie didn’t answer. She just pressed closer, her body already humming in anticipation of the new, perfect loop.
