Chapter 23: Triple Penetration Training
lot
The sterile blue light of the medical bay felt colder than usual, leaching the warmth from Selina’s sweat-slicked skin. She was suspended, limbs held taut by thick straps anchored to the ceiling and floor. The spreader bar between her ankles was Jason’s latest innovation – polished titanium rods that hissed pneumatically, forcing her legs impossibly wide, tendons singing in protest. Her cunt and asshole, still slick and stretched from Jason’s earlier brutal fucking, felt exposed, vulnerable, gaping slightly in the cool air. The milking pumps still tugged rhythmically at her swollen, sensitive nipples, sending jolts of sensation that were less pain now, more a deep, insistent thrumming ache.
“Hold still, kitten,” Dick murmured, his voice a low counterpoint to the hum of machinery. He knelt between her splayed legs, a bottle of thick, clear lubricant in one hand. His blue eyes were focused, analytical, scanning her trembling body. He squeezed a generous stream onto his gloved fingers, the gel cool against her overheated flesh. His touch was deliberate, tracing the swollen folds of her cunt, slicking her asshole, then moving higher, towards the tiny, flushed opening nestled above.
Selina whimpered, a high, breathy sound. Her green eyes, usually sharp and calculating, were glazed, pupils blown wide. The spell woven into the restraints, the air, maybe even the serum pumping through her veins, did its work. Pain registered, a sharp, stretching awareness, but it was instantly transmuted, twisted into a molten wave of pleasure that crashed through her core. She felt every touch, every intrusion, as pure, overwhelming sensation.
“There’s my greedy little peehole,” Jason’s voice cut through the haze, rough and darkly amused. He stood beside Dick, holding two gleaming metal rods. They weren’t like the monstrous, ribbed sound from before. These were thinner, double-barreled, their surfaces etched with intricate spirals that promised friction. Their tips were bulbous, designed to stretch. “Remember how good it felt last time? How you cooed for daddy when he stuffed you full?”
“Y-yes,” Selina gasped, her hips giving an involuntary jerk against the restraints. “Felt… felt so good, Jason. So full.”
Dick’s slicked fingers found her urethra. He pressed gently, then firmly, the tip of one finger breaching the tight ring of muscle. Selina cried out, a sound that dissolved instantly into a shuddering moan. “Ohhhh… fuck…”
“Easy,” Dick soothed, though his eyes held no softness, only intense concentration. He worked his finger deeper, a slow, relentless invasion, coating the sensitive inner passage with lube. Selina’s breath hitched, her body arching as much as the straps allowed. The sensation was intense, a burning stretch that ignited fireworks behind her eyelids, flooding her system with endorphins. Dick withdrew his finger, leaving her peehole clenching around emptiness.
Jason handed him one of the twin sounds. Dick coated it liberally, the metal gleaming wetly under the blue lights. He positioned the bulbous tip against Selina’s tiny opening. “Deep breath, Selina.”
She sucked in air, bracing. Dick pushed.
The stretch was immediate, intense. The bulb forced its way past the resisting muscle, a hot, tearing sensation that vanished instantly beneath the spell’s alchemy, replaced by a deep, resonant throb of pleasure radiating up into her belly. Selina gasped, her cunt clenching wetly. “Oh god… oh fuck…”
Dick twisted the sound slightly as he fed it deeper, the etched spirals dragging deliciously against her inner walls. Selina’s head thrashed against the padded headrest. “Yes! Deeper! Please!”
He pushed steadily, the metal rod sliding further into her urethra, stretching her impossibly. Jason watched, a predatory gleam in his eyes, already coating the second sound. “Told you she’d beg for it,” he growled. “Filthy little piss-slut loves being stuffed.”
Dick reached the hilt, the base of the sound snug against her flushed flesh. Selina panted, her chest heaving against the straps holding her torso down. The sensation was overwhelming – a constant, stretching fullness deep inside her core, vibrating with every pulse of her frantic heartbeat. The milking pumps tugged harder, milk beading at the tips of her nipples.
“Feels… feels so fucking good,” she slurred, her voice thick with bliss. “So full…”
“Not full enough,” Jason stated flatly. He nudged Dick aside, taking position. He didn’t ask. He simply pressed the lubricated tip of the second sound against her already stretched opening, right beside the first.
“Jason, wait—” Dick started, but it was too late.
Jason shoved.
The resistance was greater this time. Selina screamed, a raw sound ripped from her throat, but again, it transformed instantly. The scream became a keening wail of ecstasy as the second bulb forced its way in alongside the first, stretching her urethra wider than it had ever been. The twin rods filled her, a burning, impossible stretch that the spell converted into pure, liquid fire flooding her veins. Her body convulsed, muscles spasming wildly against the restraints.
“Fuck! Fuck! YES!” she shrieked, tears streaming down her temples. “Oh god, Jason! More! Stretch me!”
Jason grunted, forcing the second sound deeper, twisting it savagely. The etched patterns grated against her inner walls, against each other. Dick watched, his jaw tight, a flicker of something unreadable in his eyes before he masked it. He moved behind Selina, his hands slicking his own cock, already hard and glistening.
“Hold her wide,” Jason ordered Dick, his voice thick with exertion and dark satisfaction. He kept twisting the sounds, watching Selina writhe and sob with pleasure. Dick positioned himself at her exposed asshole, his cockhead pressing against the loosened ring of muscle slick with lube.
With one brutal thrust, Dick buried himself to the hilt in her ass. Selina’s cry was guttural, choked. The deep penetration, combined with the agonizingly pleasurable stretch of her urethra and the relentless pull on her nipples, pushed her towards the edge. Her vision swam.
“Fuck her cunt, Jason,” Dick gritted out, beginning a hard, rhythmic pounding into her ass. “Stuff her greedy hole.”
Jason didn’t hesitate. He released the sounds, leaving them buried deep inside her peehole, stretching her obscenely. He grabbed his own thick cock, slicked it hastily, and lined up with her dripping cunt. Her swollen folds were slick, glistening, the entrance gaping slightly from the spreader bar and her arousal. He slammed home.
Selina’s world dissolved into sensation. Dick’s cock pistoning deep into her ass, a hard, driving rhythm that shoved her forward onto Jason’s thrusts. Jason’s thick length filled her cunt, stretching her differently but just as completely, hammering against her cervix with each powerful drive. The twin sounds shifted inside her urethra with every movement, a constant, maddening friction. The milking pumps tugged relentlessly.
“Oh fuck! Oh fuck! Oh fuck!” Selina chanted, a broken litany. Her body was a vessel, filled, stretched, used. The pleasure was a physical force, a tsunami obliterating thought. She felt Jason’s balls slapping against her ass, Dick’s hips impacting her cheeks. The sounds of wet flesh slapping, their grunts, the hum of machines, filled the sterile bay.
Jason’s thrusts grew frantic, brutal. “Gonna fill this greedy cunt!” he snarled. “Gonna pump you full!”
Dick’s rhythm hitched, his breathing ragged. He drove deep, grinding against her ass. “Take it, Selina… take it all…”
Jason roared, a sound of pure animal release. His cock pulsed violently inside her, flooding her cunt with thick, hot spurts of cum. The sensation, the sheer violation of it, tipped Selina over the edge. Her orgasm detonated, a supernova of sensation that ripped through her. Her cunt clamped down on Jason’s pulsing cock, her ass clenched around Dick’s, her urethra spasmed wildly around the invading metal rods. Milk sprayed from her nipples in thin streams, hitting her chin and chest.
Dick followed seconds later, groaning deep in his chest as he emptied himself into her ass, his thrusts slowing to deep, grinding pulses.
They stayed like that for long moments, panting, the only sounds their harsh breaths and the continued hum of the pumps still drawing milk from Selina’s sensitized breasts. Jason pulled out first, his cock slick and glistening. Dick withdrew more slowly, his cum leaking from her gaping asshole.
Selina hung limp in the restraints, utterly spent. Bliss radiated from her core, a warm, heavy lethargy. Her peehole remained obscenely stretched by the twin sounds, her cunt dripped Jason’s seed, her ass leaked Dick’s. She turned her head slightly, her green eyes finding the reflective surface of a nearby monitor. Her reflection stared back – flushed, tear-streaked, utterly debauched, milk drying on her skin.
A slow, dreamy smile spread across her swollen lips. She licked them, tasting salt and sweat. Her voice, when it came, was a husky whisper, thick with satisfaction. “So… so good,” she murmured to her reflection, her eyes drifting half-closed. “Feels… so fucking good…” Her smile widened, blissful and vacant. “Never stop…”n
The sticky warmth of Jason’s cum oozing from her well-used cunt was the only thing grounding Selina in the moment. That, and the relentless, deep ache where the twin sounds remained lodged in her peehole, a constant, stretching reminder. Dick wiped sweat from his brow, his gaze briefly meeting hers – a flicker of something unreadable, almost troubled, before it shuttered closed. Jason, however, beamed with dark satisfaction, wiping his slick cock on her inner thigh.
"See?" Jason growled, his voice rough against the sterile hum. "Told you she could take more. Fucking greedy hole just swallows it." He traced a calloused finger around the base of the sounds protruding from her urethra, making her jolt. The touch, even through the haze of bliss, sent sparks skittering up her spine. "Ready for the next course, kitty?"
Dick sighed, a soft exhalation lost in the machinery's drone. He moved to a nearby tray, the chrome surface gleaming under the blue lights. He picked up a string of large, obsidian-black beads, each slightly bigger than the last, connected by thin, flexible silicone. They looked obscenely thick. "Lubed and ready," he stated flatly, holding them up. The largest bead glistened.
Jason’s grin turned predatory. "Perfect. Daddy’s gonna fill that greedy little piss-tube proper." He took the beads from Dick, his fingers closing possessively over them. He positioned the tip of the first, smallest bead against her already stretched urethral opening, right beside the twin metal rods. The cold silicone felt alien, intrusive. "Gonna stuff you so full, slut. Make that clit scream."
Selina whimpered, anticipation coiling hot and heavy in her gut. The previous orgasm still thrummed through her, a low-level buzz, but the promise of more, of being stretched further, ignited a fresh wave of desperate need. "Please," she breathed, her voice raspy. "Jason... please stuff me." Her hips strained uselessly against the titanium spreader bar.
He pushed.
The first bead slid in alongside the sounds, a tight, burning stretch that momentarily stole her breath. The spell worked its alchemy instantly; the burn dissolved into molten gold, radiating deep into her pelvis. "Ohhhnnnngggggg!" The moan was guttural, drawn out. Her cunt clenched, spilling a fresh trickle of Jason’s cum onto the cold med-bay floor. The milking pumps kicked up a notch, rhythmic tugs intensifying on her tender nipples.
"Tight little fuck-tunnel," Jason grunted, applying steady pressure. He fed the bead deeper, its rounded bulk forcing her urethra wider, stretching the delicate tissues impossibly thin around the existing metal invaders. Dick watched, his jaw tight, hands clenched at his sides. He didn't intervene.
Jason pushed the second bead in. Larger. Thicker. The stretch intensified exponentially. Selina gasped, eyes rolling back. The sensation was overwhelming – a profound, internal pressure, a fullness that bordered on bursting, yet the spell remade it into pure, unadulterated ecstasy. "F-FUCK! YES! Stretch it! Stretch my peehole!" Her voice was ragged, desperate.
Bead after thick, obsidian bead followed. Jason worked them in with brutal efficiency, twisting slightly, forcing them deeper into her ravaged urethra alongside the metal. Each one stretched her wider, filled her fuller. Sweat beaded on her forehead, mixing with the milk drying on her chest. The sounds of her choked gasps, the wet squelch as each bead disappeared inside her, the hum of the pumps – it filled the cold chamber.
"Look at that," Jason breathed, awe laced with cruelty. He was nearing the largest bead. Her urethral opening was stretched into a dark, glistening 'O', obscenely wide, stretched thin and pink around the black silicone and gleaming metal already packed inside. "Fucking beautiful. Beloved clit slut showing off her greedy hole."
He pressed the final, monstrous bead against her entrance. The pressure was immense. Selina whimpered, a high-pitched keen. He pushed. Hard. Her body arched violently against the restraints, tendons standing out on her neck. The massive bead forced its way past the straining ring of muscle, stretching her urethra beyond anything she'd ever imagined. It burned, impossibly, but the burn was instantly consumed by a cataclysmic wave of pleasure so intense it bordered on agony.
She came.
It ripped through her like a lightning strike. Her entire body convulsed, muscles locking rigid. Her cunt gushed, splattering the floor beneath her. Her asshole clenched around nothing, spasming wildly. The urethral sounds and the newly buried anal plug, responding instantly to her climax, expanded. Inside her peehole, the metal rods thickened fractionally, pressing harder against the silicone beads already straining her walls. The plug in her ass swelled, stretching her back passage wider, triggering another ripple of intense, involuntary pleasure-pain. "AAAAAAAHHHHHHHH! FUCK! FUCKING CUMMING!" she screamed, the sound raw and shattered. Tears streamed freely.
Jason held the bead deep, grinding it inside her as she thrashed. "That's it! Cum on it, slut! Cum on daddy's beads stuffing your fuckhole!" He twisted the entire strand buried inside her, the beads shifting, grinding against the expanded sounds, against each other.
Wave after wave crashed over her. Each orgasmic spasm triggered the expansion again – the sounds pressing harder, the plug stretching her ass wider, which made her clench harder, which triggered another spasm. It was a feedback loop of overwhelming sensation. Her vision whited out. She felt stuffed to the brink, stretched impossibly wide in both holes, her entire lower body a nexus of excruciating, exquisite fullness.
As the violent tremors finally began to subside, leaving her limp and gasping, utterly hollowed out, a profound lethargy settled deep in her bones. Bliss, pure and terrifying in its intensity, flooded her veins. Jason slowly withdrew his hand, leaving the entire string of beads locked deep inside her urethra alongside the sounds, her peehole stretched wide around the protruding end of the largest bead. Her asshole remained stretched taut around the expanded plug.
Her head lolled. She stared sightlessly at the ceiling's harsh lights. A slow, utterly vacant smile touched her swollen lips. Words bubbled up, thick and syrupy with submission. "So... stuffed," she slurred, her voice barely audible. "Feels... perfect. Owned." She shifted slightly, a faint whimper escaping as the beads shifted deep inside. "Jason's cocksleeve... owned... by my big clit... and his toys." Her eyes fluttered closed, a single tear tracing a path through the milk drying on her cheek. "Never... take them out..."
