Chapter 7: Perfect Fit Conditioning
The sterile chill of the Academy Evaluation Room seeped into Sera’s bones, a stark counterpoint to the lingering phantom heat and electric terror of Dominick’s bedroom. She shuffled forward, the institutional tile cold under her bare feet, the too-large smock they’d given her scratchy against her hypersensitive skin. Every movement felt sluggish, her muscles still twitching with the residual tremors from the shocks and the soul-crushing denials of the night. The room hummed with a low, pervasive frequency, emanating from the strange devices on each student desk – devices that looked unsettlingly like polished chrome phalluses, their bases connected to glowing consoles.
Master Thane dominated the space, not just by his towering 6'7" frame, but by the sheer, silent force of his presence. He stood near a stark, high-backed chair that looked more like a piece of medical equipment than furniture – leather restraints dangled from its arms and legs, and a complex console glowed beside it. His icy gaze swept over the assembled students, lingering for a fraction longer on Sera. She felt stripped bare under that look, her exhaustion and the lingering, throbbing ache between her legs suddenly magnified.
"Blake," Thane’s deep voice cut through the hum, making her flinch. "Center stage."
Her throat tightened. She felt the eyes of the other students – some curious, some apprehensive, some faintly pitying – as she walked towards the imposing chair. The memory of Dominick’s words – ‘Your pussy will memorize every vein’ – echoed sickeningly. This was the culmination. The ‘schooling’.
"Sit," Thane commanded, gesturing to the chair. The leather was cold, unforgiving. He moved with efficient, predatory grace, securing the wide cuffs around her wrists and ankles. The buckles clicked shut with finality. He adjusted the backrest, tilting it slightly, forcing her hips forward, her legs splayed wide apart. The position was brutally exposing. The thin smock offered no modesty; she might as well have been naked.
Thane stood between her legs, his expression impassive as he surveyed the angry red lines and faint bruising encircling her hips and upper thighs – the stark testament to the chastity belt’s constant embrace during the torturous night. His index finger, cool and impersonal, traced one of the deeper welts just above her pubic bone. She sucked in a sharp breath, the touch sending a jolt of unwanted sensation through her raw nerves. "Persistent," he murmured, his voice devoid of any warmth. "Good. Shows commitment." His finger dipped lower, brushing the edge of the steel belt itself, still locked firmly over her mound. He hooked a finger into the narrow gap between the belt and her skin, right above her clit. "Swollen. Sensitive. Excellent baseline."
He turned to the console, his fingers dancing across the touchscreen. A mechanical whir sounded, and a gleaming metal arm extended from the base of the chair, terminating in a device that made Sera’s stomach lurch. It wasn't just a dildo; it was an instrument. Sleek, black, matte-finished, thick veins molded realistically along its substantial length. Wires snaked from its base into the console. Tiny sensors dotted its surface. At its tip, a cluster of electrodes glinted wickedly.
"Dominic Thorne," Thane stated, his voice echoing in the silent room. The students watched, rapt. "Seven point two inches. Five point eight inch circumference." He picked up the device, its unnatural coolness radiating even from a distance. "Your assignment, Blake, is muscle memory. Your cunt will learn the exact topography. The ridges. The veins. The flare of his cockhead. It will learn to embrace it perfectly. To squeeze with precise, welcoming pressure along its entire length. Not a millimeter of tolerance for error."
He applied a clear gel to the monstrous thing, the lubricant catching the harsh overhead lights. Sera squeezed her eyes shut, bracing herself. The cold tip pressed against her, nudging the small, punishing opening in the chastity belt. It was too big. Much too big for that aperture.
"Open," Thane commanded, not to her, but to the machine. The belt emitted a faint click, the locking mechanism over her vulva retracting just enough, creating a tight, unforgiving ring. He pressed the head of the dildo against it. "Relax, Blake," he said, though it was clearly an order, not advice. "Resistance increases calibration time. And pain."
She tried. She really fucking tried. But her body, locked in terror and still buzzing with unresolved need from the night, clenched instinctively. Thane pushed. The thick, unyielding silicone head forced its way through the tight ring of steel. Sera gasped, a sound ripped from deep in her chest, as her sensitive flesh was stretched brutally around the intrusion. It burned. Tears sprang to her eyes. He pushed further, the thick shaft dragging against her inner walls, the molded veins catching, stretching her in ways that were shockingly invasive. He didn't stop until the base of the dildo met the steel of the chastity belt, buried inside her to the hilt. Her cunt felt stuffed, stretched to its absolute limit, the cold, hard shape a violation that stole her breath. A low moan escaped her, mixed with pain and a terrifying spark of something else.
"Deep breath," Thane instructed, his eyes fixed on the biometric screens that suddenly flared to life beside her. Waveforms spiked and danced – heart rate skyrocketing, vaginal muscle tension maxed out, skin conductivity off the charts. "Now, the real work." He tapped the console. A low, rhythmic vibration started deep within the dildo, mimicking the slow, powerful thrusts of a cock. It was an exact replication of Dominick’s recorded pattern – a long, slow withdrawal almost to the tip, then a firm, deep plunge back to the base.
"Feel the ridge beneath the head," Thane said, his voice hypnotic. "Feel it drag against your inner walls. Feel your muscles ripple around the main shaft. Concentrate, Blake. Every contour. Every vein. Your cunt must map it perfectly."
The vibration intensified slightly with each inward thrust. It was maddening. The deep, rhythmic invasion, the mechanical impersonation of Dominick’s possession, combined with her own exhausted, hyper-aroused state, sent conflicting signals through her shattered nervous system. Pain warred with a treacherous, building pressure. Her inner muscles fluttered weakly around the intruder. The biometric screen showed the tension graph dip slightly.
CRACK!
Sera screamed. A sharp, agonizing jolt of electricity – ten volts – ripped through the dildo directly into the tender, stretched flesh of her inner walls and her swollen clit, where the electrodes pulsed. It wasn't the deep muscle lock of Dominick's restraints; this was a white-hot stab, a violent cramp deep in her core. Her body convulsed against the leather straps, her back arching off the chair.
"Inadequate," Thane stated flatly, watching the screen. The dildo resumed its relentless thrusting rhythm. "Squeeze, Blake. Welcome it. Embrace its shape. Or be reminded."
Trembling, sweat beading on her forehead, she tried to focus through the aftershocks of pain. She could feel the thick vein running along the underside of the fake cock as it withdrew. She felt the pronounced ridge of the head scrape her inner entrance. She clenched internally with everything she had as it plunged back in. The screen showed a spike in muscle tension. The vibration hummed. No shock.
"Better," Thane acknowledged, his voice devoid of praise. "Hold it."
She held, trembling, the thick silicone stretching her unbearably, the vibrations setting her raw nerves alight. The rhythm was constant, unyielding. Withdrawal. Pause. Deep penetration. As the dildo pulled back again, nearing the tip, her concentration faltered. Her exhausted muscles, still spasming from the shock, couldn’t maintain the grip. The tension graph dipped below the threshold.
CRACK!
Another scream tore from her throat, raw and ragged. The electricity seared her from the inside, focusing with cruel precision on her clit. Her vision blurred. She tasted blood – she’d bitten her lip. The dildo kept thrusting. Out. Dragging. Stretching. Vibrating.
"Focus!" Thane snapped. "Your cunt belongs to that cock. It must know every inch. Every. Fucking. Curve. Squeeze like you mean it, Blake, or this lesson will be excruciatingly long."
Sobs hitched in her chest. She was a puppet strung between agony and a terrifying, unwanted cresting wave of sensation amplified by the vibrations and the brutal fullness. The rhythm was ingrained now: the slow drag out, the threat of emptiness and failure, then the deep, stretching plunge, demanding perfection. She clenched desperately on the inward thrust, visualizing Dominick’s cock, feeling the rubber veins bite into her tender flesh. The screen showed acceptable tension. No shock. Withdrawal. Her focus wavered. The graph dipped.
CRACK!
"FUCK!" she screamed, her body jerking like a landed fish. Tears streamed freely now, mixing with sweat on her cheeks. The cycle became her universe: agonizing concentration rewarded by a fleeting moment of non-punishment, then inevitable failure met with searing voltage. Her cunt felt raw, abused, yet the relentless stimulation and her own violated physiology kept a sick, hot throb building low in her belly, a counterpoint to the pain. The biometric screens painted a vivid picture of her torment – jagged peaks of agony-induced adrenaline, valleys of desperate clenching, all overlaid on a terrifyingly high baseline of arousal that spiked with each shock.
Withdrawal. She braced, muscles screaming from the effort of constant clenching. The thick head reached her entrance. She squeezed with everything she had left, a silent plea. The dildo thrust deep. The sensors registered acceptable pressure along the shaft. No shock. But the vibration intensified, sending waves of sensation radiating from her core. The thick ridge beneath the head dragged exquisitely over a cluster of nerves deep inside as it plunged home. A ragged cry, this time not of pain, escaped her. It was too much. The combination of the punishing fullness, the relentless rhythm, the deep vibrations, the edge of pain, and her utterly primed state pushed her towards the brink she’d been denied all night.
She felt it gather, a terrifyingly familiar pressure coiling, tightening, threatening to detonate. Her hips pushed up against the restraints, seeking more, her inner walls spasming erratically around the invading silicone. "No... please..." she whimpered, not sure what she was begging for – release or cessation.
The dildo withdrew. Slowly. The ridge catching. Her inner muscles, reacting to the impending loss and the cresting wave, fluttered wildly. The tension graph plummeted below the threshold.
CRACK!
The shock hit at the precise moment her body was primed for orgasm. Agony and ecstasy collided in a cataclysm of sensation. It wasn't release; it was obliteration. A white-hot detonation of pain that ripped through her core, short-circuiting the building climax into a violent, full-body spasm. Her scream choked off into a guttural sob. She collapsed back against the chair, trembling uncontrollably, tears streaming, her cunt throbbing with a raw, empty ache that felt deeper than the physical. The dildo remained still, buried deep.
Silence hung heavy in the room, broken only by Sera's ragged breaths and the low hum of the machines. Thane studied the biometrics – the jagged spike that wasn't quite an orgasm, the elevated heart rate, the off-the-charts arousal flatlining at maximum. He tapped the console. The dildo’s vibration ceased. With a soft mechanical whir, it withdrew fully, slipping wetly out of her, leaving her gaping and exposed to the cold air, a thin trail of lubricant and her own slickness glistening on her inner thighs.
The cold air hit Sera’s exposed, abused flesh like a physical blow. She flinched, every nerve ending raw and screaming. Tears blurred the harsh fluorescent lights overhead. A sob caught in her ravaged throat, tasting of salt and humiliation. The deep, throbbing ache between her legs was a constant, brutal reminder of the violation, the shocks, the denied peak that had left her trembling and hollow.
Thane observed her dispassionately, his gaze fixed on the biometric screens showing her vital signs slowly stabilizing from their frantic peaks. Her vaginal canal, mapped on the display, pulsed with residual tremors. He didn't speak immediately, letting the silence stretch, thick with the scent of her sweat, the sterile tang of the room, and the lingering ozone from the shocks. His large hand hovered over the console, fingers tapping thoughtfully.
"Sufficient baseline established," he finally declared, his deep voice cutting through her ragged breathing. He moved away from the console towards a tray of gleaming instruments beside the chair, each one a promise of further torment. Sera’s eyes widened in fresh dread, her exhausted body tensing against the restraints. She braced for another invasion, another agonizing stretch.
Instead, Thane selected a different device. It was still substantial, but noticeably sleeker and shorter than the monstrous replica. It looked exactly like the replica of Dominick's cock, but was slightly smaller with tiny, embedded electrodes glowed faintly blue around the base and along its shaft. "Mitigating factor introduced," he stated, his tone clinical, offering no comfort. He coated it liberally with the same cold, clear gel.
Sera couldn't suppress a whimper as the cool tip pressed against her swollen, sensitive entrance. The memory of the brutal stretching was excruciatingly fresh. But Thane pushed steadily, the slick head parting her labia and sliding into her with surprising ease. It was still an intrusion, filling her aching channel, but the lack of violent resistance, the absence of that tearing stretch, was an almost shocking relief. It seated deep, nestled against her cervix, its girth demanding but not punishing. Its presence was undeniable, a constant occupying pressure.
"Activating constant stimulation protocol," Thane announced, tapping his console. The device inside her cunt came alive. Not with forceful thrusts, but with a deep, pervasive hum. Vibrations radiated outwards from its core, thrumming through her pelvic floor, buzzing against her G-spot, sending jolts of sensation up her spine. Simultaneously, a low-level electrical current pulsed through the embedded electrodes. Not the sharp, agonizing bite of the shocks, but a persistent, tingling charge.
Sera gasped. It wasn't pain. It was… relentless awareness. Her pussy, raw and hypersensitive, clenched instinctively around the vibrating intrusion. The electrical tingle amplified the vibration, making the involuntary grip stronger, more insistent. Her inner muscles rippled and squeezed, trying to contain the buzzing invader, stimulated into constant, rhythmic spasms by the combination of vibration and low-grade current. It was an insidious, inescapable demand. Her body was being forced to engage, constantly, intimately, with the object inside it. "Oh god," she whispered, her hips shifting minutely against the chair, caught between trying to escape the sensation and pushing deeper into it.
Thane watched the biometrics. Muscle tension remained high, but stable. Arousal levels, instead of spiking and crashing, plateaued at a simmering, persistent high. "Optimal clenching response achieved," he noted dispassionately. "Maintenance cycle initiated." He leaned over her, his large frame blocking the light. With deft, practiced movements, he manipulated the locking mechanism of the chastity belt still encircling her hips. He didn't remove it. Instead, he meticulously secured it back into place over her vulva, the cool steel plate pressing firmly against her pubic mound. The small aperture snapped shut around the base of the vibrating device protruding from her, locking it firmly inside her cunt. She was sealed. Filled. Stimulated. Trapped.
"There," Thane said, his voice close to her ear, a low rumble that vibrated in her bones. "Class awaits, pet. Consider this… your study aid. Your cunt will learn its purpose. Constant engagement. Constant awareness. Go." He released the leather restraints with swift clicks. The sudden freedom of her limbs felt alien, jarring. Her body felt heavy, uncoordinated.
Sera slid shakily off the chair, her legs almost buckling. The sensation was overwhelming. The vibrator buzzed incessantly deep within her, the electrical tingle a constant companion. Every step sent fresh waves of sensation radiating through her core. The silicone shifted minutely inside her stretched, sensitive channel with each movement, triggering another involuntary clench amplified by the charge. Her labia felt swollen, rubbing against the steel belt and the base of the device locked tight against her. It wasn't sharp pain, but a relentless, low-grade torment that kept her teetering on the edge of arousal, her cunt constantly working, gripping, milking the intruder. Slickness, both lube and her own treacherous arousal, coated her inner thighs beneath the short smock.
She walked, stiff-legged, towards the heavy metal door Thane indicated. The other students watched her pass, their expressions unreadable. She felt the weight of their stares, the flush burning her cheeks. The buzzing inside her seemed louder in the sudden quiet of the room, a constant, humiliating reminder. She pushed the door open, stepping into the sterile corridor. Fluorescent lights hummed overhead. The distant sound of a lecturing voice drifted from a room down the hall.
Each step was an effort, a battle against the relentless stimulation vibrating through her pelvis. Her pussy clenched rhythmically, helplessly, around the device, the slight electrical pulse making each contraction sharp and defined. She focused on putting one foot in front of the other, the cold floor beneath her bare soles, the scratchy fabric of the smock. The door to the classroom loomed ahead, partially open. The lecture droned on inside. She paused, taking a shaky breath, feeling the insistent thrum deep inside her body. A fresh surge of wetness seeped out around the base of the locked device. She gripped the doorframe, knuckles white.
Sera pushed the heavy door open, the corridor's sterile chill replaced by the thick warmth of bodies and the low murmur of Instructor Allen's voice. She shuffled in, the relentless vibration locked deep in her cunt making each step a tremulous negotiation between balance and the insistent, buzzing pressure against her cervix. The low-grade electrical pulse ensured her inner muscles kept rhythmically clenching the intruder, a constant, humiliating reminder of Thane's 'study aid'. Sweat beaded her upper lip, her cheeks burning under the gaze of the other students already seated at their desks. Allen paused mid-sentence, his sharp eyes snapping to her, taking in her disheveled smock, the tear tracks, the way her thighs trembled almost imperceptibly with every internal ripple.
"Blake," Allen stated, his voice crisp, cutting through the classroom hum. "Linger at the threshold and disrupt, or take your place?" He gestured dismissively towards an empty desk near the front, the peculiar, phallic-shaped devices humming softly on each surface. The command was casual, almost bored, but laced with steel. Sera swallowed hard, the vibration seeming to echo in her throat as she lurched forward, the movement jostling the device inside her, triggering a fresh wave of slickness that seeped warm against the steel belt. She collapsed into the hard plastic chair, the posture forcing the vibrator’s base to press more firmly against her clit through the chastity plate, eliciting a tiny, choked gasp she struggled to smother. The other students watched, some with feigned disinterest, others with undisguised curiosity flickering in their eyes.
Allen resumed his lecture on submissive posture, his words washing over Sera as a distant buzz competing with the one consuming her pelvis. She gripped the edge of the desk, knuckles white, trying to anchor herself against the relentless internal massage and the low thrum of electricity coaxing her cunt to grip harder. Every shift in her seat, every breath that moved her diaphragm, sent new currents of sensation radiating outwards. Her focus fragmented. Allen’s voice suddenly cut through her haze, sharp and close. "Blake. Focus is a discipline. Yours appears lacking. Front and center. Now." He stood beside her desk, tapping its surface impatiently. The abrupt command sent a jolt of fear through her, momentarily overriding the physical torment. She rose unsteadily, the vibrator shifting heavily inside her.
"Assume the position," Allen commanded, pointing to the clear space before his lectern. "Knees. Hands clasped behind your back. Head up. Eyes front." Sera complied, the simple act of kneeling sending vibrations shuddering deep into her core, the pressure against her G-spot flaring. She locked her trembling hands behind her, arching her back slightly as instructed, the posture thrusting her hips forward slightly, making the vibrator’s presence even more pronounced. She stared straight ahead, focusing on a chip in the plaster on the far wall, trying to ignore the damp heat pooling beneath the steel belt, the constant pulse making her inner muscles flutter helplessly. Allen circled her like a predator assessing prey.
"You failed to absorb the lesson," he stated, stopping directly in front of her. "Perhaps practical application is required. Oral discipline reinforces focus, Blake. It demands absolute presence." He unzipped his trousers with deliberate slowness, the sound loud in the quiet room. Sera’s breath hitched, anticipating the familiar weight and smell. But instead of flesh, he withdrew a thick, gleaming black dildo, identical to those on the desks but slightly larger. Its surface had a subtle sheen, and a small, almost invisible tube ran along its underside to a discreet pump mechanism hidden in his pocket. He gripped it firmly at the base, holding it level with her mouth. "Deep throat protocol. You know the drill. Take it. All of it. Maintain suction. Eyes open."
Sera opened her mouth obediently, her tongue extending slightly. Allen pressed the cool, broad silicone head against her lips. "Wider," he ordered. She stretched her jaw as far as it would go. He pushed forward, the thick shaft sliding over her tongue, filling her mouth completely. She gagged reflexively, her throat muscles convulsing. "Control it," Allen snapped, not easing the pressure. He pushed further, the bulbous head pressing against the back of her throat. Tears welled instantly as her gag reflex spasmed violently. She fought it, breathing harshly through her nose, saliva pooling in her mouth and spilling over her chin. The vibrator in her cunt buzzed incessantly, a counterpoint rhythm to the choking sensation in her throat. Allen watched her struggle, his expression impassive.
"Relax your throat, Blake," he instructed coolly. "It's just silicone. Submit to it." He pushed relentlessly. The thick head forced its way past her resisting throat sphincter, bulging obscenely in her esophagus. Her eyes bulged wide, watering uncontrollably, a strangled whine escaping around the intrusion. The shaft followed, impossibly thick, stretching her throat wide open. She could feel every molded ridge, every vein on the fake cock as it filled her passage. Her body trembled violently, the vibration locked in her pussy seeming to intensify, making her clench around it involuntarily as she fought not to vomit. Allen pushed until the base of the dildo met her lips, buried deep into her gullet. Her neck strained, her airway constricted to a desperate whistle. "Suck," he commanded, his thumb pressing a hidden button on the pump mechanism in his pocket.
A thick, viscous fluid, warm and salty-sweet with a chemical tang reminiscent of cheap lube and something vaguely biological, pulsed directly from the tip of the dildo, flooding the back of her throat. The sudden burst triggered another violent gag, her stomach heaving. "Swallow," Allen ordered, his voice devoid of inflection. "Every drop. Show me your acceptance." Sera panicked. The fluid was thick, coating her throat, overwhelming her senses. She gagged, trying to expel it, but the dildo was lodged too deep, blocking the path. More fluid pumped out, a heavy stream this time. It filled her mouth, thick and glutinous, threatening to choke her entirely if she didn't comply. Tears streamed down her face, mingling with the saliva and the artificial cum spilling from the corners of her stretched lips.
She had no choice. With a desperate, convulsive swallow, she forced the thick, slimy liquid down her abused throat. It felt like swallowing cold, congealed grease. It bulged visibly as the mass moved downwards, a grotesque lump sliding beneath her skin. Allen pumped again. More fluid surged. "Again," he commanded. "Swallow it all. Let it fill you." Sera swallowed convulsively, her throat working frantically around the rigid shaft still buried deep, each gulp a painful struggle against the gag reflex and the sheer volume of the viscous fluid. The taste – artificial salt, plastic, and something vaguely bitter – coated her tongue, her sinuses. Her cunt clenched violently around the vibrator in response to the choking desperation, the electrical pulse sharpening the spasm. Fluid leaked from her nose now, dripping onto the floor. Allen watched the bulge travel down her neck, his gaze clinical. "Good girl," he murmured, the praise empty as he pressed the pump once more. "Now, hold it. Deep. Suck it clean." He held her head firmly, the dildo anchored deep in her throat, as another thick pulse of the fake cum flooded her, the viscous weight demanding immediate, humiliating submission. Her throat strained, bulging obscenely as she swallowed frantically, the vibrations deep inside her own body a mocking echo of her choked gasps.
