Chapter 25: Chapter 25
The sterile chill of the Wayne Biotech lab settled deep into Selina’s bones, a stark contrast to the liquid fire simmering low in her belly. She lay prone on a padded examination table, the surface cold against her bare skin. Her wrists and ankles were secured with padded cuffs connected to recessed points in the table, not painfully tight but undeniably firm. The hum of the lab’s advanced climate control and processing units was the only sound besides her own ragged breathing.
Dick stood near her head, his fingers gently tracing the line of her jaw, his usual playful smirk replaced by an intensity that both thrilled and unnerved her. Jason hovered near her spread legs, his gaze predatory as he held a small, crystalline vial filled with a luminescent blue liquid – the Kryptonian solution. The remnants of their earlier… testing… lingered in the air – the sharp tang of her arousal, the slick sounds still echoing faintly in her memory, the phantom stretch of Jason’s fist buried deep inside her cunt while Dick narrated every brutal, glorious inch.
"Ready for the upgrade, kitten?" Dick murmured, his thumb brushing her lower lip. His blue eyes held hers, searching for any flicker of hesitation. "No more accidents. Just pure, sweet need."
Selina’s heart hammered against her ribs. Excitement warred with a primal apprehension. The memory of Jason’s electrodes on her engorged clit-cock, forcing orgasm after humiliating orgasm as she watched footage of herself begging… it was a raw, exposed nerve. This was different. Permanent. "Fuck yes," she breathed, her voice husky. "Make it drip. Make it squirt. Just… just fill me with it." The thought of her bladder repurposed solely for this, for the evidence of her pleasure, sent a fresh wave of heat flooding her core.
Jason grunted, uncapping the vial. The blue liquid glowed faintly in the lab’s sterile light. "Hold her steady, Dickie-bird. This needs precision." His voice was rough, lacking Dick’s measured calm, charged with the anticipation of control. He moved between her legs, his muscular frame blocking her view as he positioned himself. The cool air kissed her exposed folds, already slick and swollen.
Selina tensed instinctively as she felt the cold tip of a specialized applicator nudge against her urethral opening. It wasn’t painful, just intensely intimate, invasive. "Easy, Selina," Dick soothed, his hand resting possessively on her shoulder. "Deep breath. Let him work." His other hand drifted down, fingertips finding the sensitive nub of her clit-cock, already hardening again under his touch. A low moan escaped her lips, her hips lifting slightly off the table despite the restraints.
"Fuck," Jason muttered, completely focused on his task. He depressed the plunger slowly. Selina gasped. It wasn’t pain, exactly. It was a deep, internal shift, a strange warmth spreading from her core upwards, a tingling pressure building low in her abdomen where her bladder sat. It felt… transformative. Alien. Intensely erotic. She could feel the liquid dispersing, integrating, rewriting her biology on a fundamental level. A bead of clear slickness welled instantly at her entrance, thicker than before, glistening under the lights.
"Jesus," Dick breathed, watching the reaction. "It’s immediate." He stroked her clit-cock more firmly, making her writhe. "Look at that. Already weeping." His voice dropped to a possessive growl. "My perfect little fountain. No more piss. Just this. Just need."
Jason pulled the applicator away, discarding it. His eyes, dark and hungry, traveled up Selina’s trembling body to meet Dick’s. "Time for the stress test?" The predatory grin was back.
Dick returned it, a feral edge glinting in his blue eyes. "Oh, absolutely. Daddy needs to see how deep his little thief can take it now." He moved his hand from her shoulder to her bound wrist, gripping it firmly. "Jason, prep her."
Jason didn’t need telling twice. He reached for a gleaming tray beside the table, selecting a large bottle of thick, clear lubricant. He coated his right hand liberally, the sound obscenely slick in the quiet lab. Then, without preamble, he pressed two thick fingers straight into Selina’s cunt, already impossibly wet from the serum’s effects and her own arousal.
Selina cried out, arching off the table. The stretch was immediate and demanding, but the serum seemed to heighten sensation, turning the invasion into a white-hot brand of pleasure. Her cunt clamped down hard, pulsing around his knuckles. "God! Jason!" she gasped.
"Tight little fuckhole," Jason grunted, working his fingers deeper, scissoring them. "Even wetter now. Like a fucking slip'n'slide." He added a third finger, stretching her entrance wide. Selina’s cries turned into desperate whimpers. Her clit-cock throbbed violently, a near-constant pulse Dick kept stoking with skilled, relentless fingers.
"Beautiful," Dick murmured, leaning close, his breath hot on her ear. "Look at my greedy girl. Taking it so well. But we need to go deeper, don't we? Need to wreck you properly. See what that Kryptonian magic really does." He nodded to Jason. "Give her your fist, little brother. Show her how much she can hold."
Jason’s eyes locked with Selina’s, a challenge and a promise. He coated his fist now, thick gel dripping onto the table beneath her. He pressed the broad base of his palm against her swollen, glistening entrance. Selina held her breath, her body trembling with anticipation and a sharp spike of fear-pleasure. This was beyond fingers. This was claiming.
"Fuck... fuck!" she screamed as Jason leaned his weight forward. His knuckles breached her, a brutal, stretching invasion that stole her breath. Her cunt strained impossibly wide around the hard ridge of his hand. Dick’s fingers became a blur on her clit-cock, pinching, rubbing, demanding.
"That's it," Dick coaxed, his voice raw with arousal. "Push down, Selina. Take it. Take Daddy’s fist." He shifted his grip, holding her hips down as Jason slowly, relentlessly, worked the widest part of his hand past her labia and into the gripping heat beyond. "Look at that stretch... fucking magnificent. Made for this. Made to be pried open."
Jason grunted, sweat beading on his brow as he fought the incredible pressure of her inner muscles. He twisted his wrist slightly, sinking deeper. Selina’s vision blurred. The pain was a sharp counterpoint to the overwhelming, mind-numbing pleasure radiating from her core and her tortured clit-cock. She could feel every ridge of his knuckles, the hard bulk of his fist reshaping her insides. And beneath it, the strange new pressure from her altered bladder surged.
"More... please..." she sobbed, the words ripped from her. "Need it... wreck me!"
Jason growled, low and triumphant. With one final, powerful thrust, he seated his fist fully inside her cunt, his wrist pressed flush against her labia. Selina’s scream echoed off the sterile walls, a sound of pure, shattered ecstasy. Her body convulsed violently around the massive intrusion. Her clit-cock pulsed like a separate heartbeat under Dick’s fingers.
And then it happened. The pressure became too much. Not just orgasm, but the new, overwhelming force centered deep within her pelvis. The Kryptonian solution activated fully. A violent spasm ripped through her lower belly, utterly distinct from her clenching cunt. With a guttural cry, Selina squirted. Not a trickle, but a thick, pearlescent jet of pure female ejaculate. It shot out with surprising force, splattering Jason's thighs and the gleaming floor beneath the table, warm and slick. The scent, musky and sweet, flooded the ozone-tinged air.
"Holy shit!" Jason barked, stunned for a moment, his fist still buried deep. "Look at that!"
Dick laughed, a dark, delighted sound. He pinched her clit-cock hard, triggering another wave of convulsions. "There it is! Fucking perfect! Her own girl-cum fountain!" He watched, mesmerized, as another pulse of thick, creamy fluid erupted from her urethra, mingling with the lube and her natural wetness coating Jason's arm. "Squirt for Daddy, you filthy little thief. Show us what we made."
Selina was beyond words, lost in a haze of overwhelming sensation. The brutal fullness of Jason’s fist pistoning shallowly now, the torturous pleasure-pain on her clit-cock, and the deep, involuntary contractions forcing more and more of that thick, alien essence from her newly repurposed core. Her body was a vessel, reshaped, filled, and now spilling over for their pleasure. She came again, the orgasm crashing over her with the force of a tidal wave, her screams dissolving into raw, animalistic cries as she sprayed another arc of glistening cum onto Jason and the sterile floor, the proof of their twisted science and her shattered control pooling beneath her. The hum of the machines seemed to swell, a cold counterpoint to the raw heat and wet chaos of the table. Jason’s eyes met Dick’s over her trembling body, both dark with primal satisfaction. They’d only just begun. The lab wasn't done with her yet.
The sterile chill of the lab air prickled Selina’s sweat-slicked skin, a harsh counterpoint to the furnace raging inside her. Jason’s fist remained buried deep in her cunt, a solid, unyielding anchor stretching her impossibly wide, each slight shift sending fresh tremors through her oversensitive core. Dick’s fingers, slick with her own juices and the thick pearlescent squirt from her newly modified bladder, never ceased their torment on her engorged clit-cock, pinching and rubbing the swollen head until her vision swam.
"Look at this fucking mess," Jason growled, his voice thick with exertion and arousal as he surveyed the glistening puddle beneath the table, a mixture of lube, her natural slickness, and the thick, alien girl-cum she’d sprayed. He flexed his wrist inside her, drawing a choked sob from Selina’s throat. "Dripping like a broken faucet. Perfect."
"Just getting started, little brother," Dick murmured, his calm tone belying the fierce hunger in his blue eyes. He released her clit-cock momentarily, reaching for a gleaming metal tray Jason had prepared earlier. Six small, wicked-looking clamps lay there, each tipped with a tiny, buzzing vibrator. "Daddy’s got some new jewelry for his biggest clit slut." Selina whimpered, a fresh wave of heat flooding her as she saw them, anticipation warring with the sheer overload of sensation.
Jason chuckled, a dark, possessive sound. "Hold her wide, Dickie. This greedy cunt needs decorating." Dick’s strong hands spread her labia further, exposing the thick, throbbing length of her clit-cock, flushed deep red and glistening. Jason picked up the first clamp. The cold metal bit into the sensitive flesh near the base. Selina gasped, arching her back against the restraints. Click. The tiny vibrator instantly buzzed to life, a low, insistent thrum.
"Fuck!" Selina cried out, the vibration resonating deep into her pelvis, amplifying the fullness of Jason’s fist. Click. Another clamp snapped onto the middle shaft, the dual vibrations setting up a discordant hum that made her toes curl. Click. A third near the swollen head. Her clit-cock pulsed violently under the assault. "Ohgodohgod!" Each clamp added a layer of exquisite, unbearable torment, the vibrations traveling straight to her core, making her cunt clench rhythmically around Jason’s imprisoned hand.
Jason worked swiftly, methodically. Click. Click. Click. Soon, six vibrating clamps adorned her clit-cock from base to tip, each buzzing at a slightly different frequency, creating a maddening symphony of sensation. The entire length throbbed and hummed, a live wire of pure, agonizing pleasure. Tears streamed down Selina’s cheeks, her body a taut bowstring vibrating under their hands. "Can't... too much...please!" she babbled, though her hips ground down desperately onto Jason’s fist.
"Shut up and take it," Jason commanded, his voice rough. He twisted his fist inside her slowly, deliberately, grinding against her inner walls. "This is what you fucking begged for, remember? In that interview? Begging to be Daddy’s stuffed little cumdump?" Dick, meanwhile, had moved, gathering lengths of deep red silk rope – his shibari tools.
"Indeed," Dick said, his voice a low purr as he began looping the rope around Selina’s torso, just below her breasts. "Our greedy girl wanted to be full. Every hole." His hands were deft, practiced, weaving intricate patterns that pulled her shoulders back, arching her spine. "She wanted to swallow. Needed it." He worked down, securing her waist, the ropes biting beautifully into her flesh, emphasizing her curves, restricting her breathing just enough.
Selina could only moan, her world reduced to the brutal fullness below, the maddening buzz on her clit, and the tightening embrace of the ropes. Dick pulled her up slightly, adjusting her position on the table. Jason maintained his fist deep inside her, a constant, stretching presence. "Open wide, kitten," Dick commanded, his fingers gripping her jaw. "Time to taste your reward."
Trembling, Selina obeyed, opening her mouth. Dick guided her head down, positioning her directly over her own groin. Her gaze locked onto her own swollen, clamped clit-cock, vibrating obscenely. Below it, her urethral opening glistened, another thick bead of the Kryptonian-modified cum welling up. "Deep throat it," Dick ordered, his voice leaving no room for refusal. "Swallow what Daddy makes you squirt."
With a choked gasp, Selina lowered her head further. Her lips touched the slick, buzzing head of her own clit-cock. The vibrations shot straight into her skull. She pushed forward, taking the thick, humming length into her mouth, gagging instantly as it hit the back of her throat. Tears blurred her vision. Dick’s hands were relentless, forcing her down until her nose pressed into her own pubic mound, her clit-cock buried deep in her gullet. She gagged violently, drool dripping down her chin.
"Hold her," Dick instructed Jason, who braced Selina’s hips firmly. Dick swiftly secured the final ropes, expertly knotting them behind her head and neck, pulling taut. The intricate harness locked her head in place, bent forward, her own clit-cock impaling her throat. She was immobilized, forced to deep throat herself, every gag reflex sending shockwaves through her clamped flesh and full cunt. Her eyes rolled back, desperate, panicked breaths whistling through her nose.
Jason watched, mesmerized, his fist still lodged deep within her spasming cunt. "Look at that," he rasped, leaning close to her ear, his voice thick with dark satisfaction. He gestured towards a small camera mounted nearby, its red light blinking – recording her 'interview'. "This is it, Selina. Exactly what you wanted to achieve. Stuffed." He twisted his fist inside her, making her shriek around the cock in her throat. "Swallowing." Another thick pulse of girl-cum spurted from her urethra directly onto her tongue, flooding her mouth with her own musky-sweet essence. She choked, swallowed reflexively. "Full." Dick’s fingers traced the ropes binding her, the vibrators humming relentlessly. "Beautiful."
Selina convulsed, a silent scream trapped in her throat blocked by her own flesh. Her body was a landscape of brutal pleasure: stretched wide open below, vibrating violently above, throat fucked by her own cocklet, drowning in her cum. Tears and drool slicked her chin. She swallowed again, the taste overwhelming, primal. Jason’s voice cut through the haze, low and possessive. "Daddy’s biggest clit slut." A fresh orgasm detonated, silent but violent, her cunt milking Jason’s fist, her bladder emptying another hot stream of cum straight down her captive throat. She swallowed, gagged, swallowed again. Consenting. Loving it. Utterly wrecked. The ropes held her fast, a beautiful, broken offering. The camera’s red light glowed steadily.
The camera’s red light glowed steadily, an unblinking eye capturing every trembling sob, every choked gulp around the slick, buzzing flesh filling Selina’s throat. Tears streamed freely, mingling with drool and the thick, alien-sweet cum still pulsing onto her tongue from her own transformed bladder. She gagged violently, the ropes cutting into her neck as her body rebelled against the relentless deep-throating, the vibrations from the clamps on her clit-cock sending electric jolts through her skull. The fullness below was a constant, brutal pressure; Jason’s fist remained a solid, stretching anchor deep in her cunt, shifting slightly with her convulsions, grinding against hypersensitive inner walls.
"Fuck, listen to her choke on it," Dick observed, his voice a low thrum of dark pleasure. He ran a fingertip along the stretched seam of her lips where they strained around her own engorged flesh. "Greedy bitch can’t get enough of her own magic fuckstick, can she? Needs it jammed down her throat." He traced the intricate ropes binding her head and shoulders, the shibari harness a beautiful, inescapable cage. "But she needs a little help staying open. Taking it all like the good little throat slut she is." He moved to the tray, fingers closing around cold, polished steel – a heavy ring gag, its interior diameter intimidatingly wide.
Selina’s eyes widened in panicked understanding above her impaled mouth, a muffled plea dying in her throat. Dick’s thumb pressed hard on her jaw hinge. "Relax, kitten. Or this will hurt." He applied pressure. A sharp, protesting pop echoed as her jaw unhinged further. The cold steel ring pressed against her teeth, then forced its way between them. He worked it deeper, past her molars, stretching her mouth obscenely wide before securing the buckle tightly at the back of her head. Instantly, the constricting pressure on her throat eased slightly as her clit-cock was no longer forced quite so deep, but the cold, rigid circle held her mouth gaping wide, vulnerable. Drool cascaded freely down her chin, dripping onto her heaving chest.
"Perfect," Dick purred, stepping back to admire his handiwork. Her clit-cock stood proud from her groin, vibrating furiously within the ring, glistening with her own spit. Her urethra pulsed below it, another thick bead of Kryptonian-modified cum swelling at its entrance. "Now suck it properly, whore. Show the camera how much you love tasting yourself." He gave her clit-cock a sharp slap, making the vibrators buzz louder against the sensitive head. Selina moaned around the steel, the sound distorted and wet, instinctively trying to close her mouth but held rigidly open. She flicked her tongue weakly against the underside of her own shaft, the taste of salt and musk flooding her senses, triggering another helpless swallow.
Jason chuckled, his gaze flicking from Selina’s debased face to the camera’s lens. "See that?" he rumbled, his voice conversational yet thick with dark pride. He twisted his fist slowly inside her cunt, drawing a ragged, gurgling scream from her gagged mouth, her body bucking against his hold. "Look how easy she takes it now. That Kryptonian juice? Reprogrammed her entire pelvic floor. Bladder’s just a fucking cum tank now, dripping non-stop." He thrust his fist deeper, knuckles grinding against her cervix, making her entire body spasm. "But her cunt? That greedy hole? It’s like fucking warm silk over steel. Stretches like a dream, grips like a vise, and floods itself slick the second you push in. Designed to be fisted. To be wrecked." Another thick stream of pearlescent cum jetted from her urethra, splattering the vibrating cock and the steel gag. "Look at her piss her girl-cum just from getting stuffed. Disgusting. Perfect."
He pulled his fist back slowly, slowly, letting her feel every ridge, every knuckle dragging through her pulsing, overstretched tunnel. A gush of mixed fluids – lube, her natural slick, the thick Kryptonian cum – followed, soaking the table beneath her ass. Selina whimpered around the gag, her cunt clenching desperately around the sudden, aching emptiness. Before she could process the loss, Jason’s slick fingers were back, not penetrating, but seeking higher. They found her urethral opening, glistening and slightly gaping from the recent ejaculation.
"Gotta plug the leak," Jason announced, his tone grimly practical. He selected a small, tapered plug from the tray, gleaming surgical steel with a flared base. It was coated in the same thick lube. With no preamble, he pressed the cool, blunt tip against her sensitive pee-hole. Selina jerked, a high-pitched mewl escaping the gag. He pushed. A sharp, invasive stretch, different from the brutal cunt-fisting, a deep, internal pressure radiating upwards. The plug slid deeper, stretching the tiny opening wide, sealing it shut. He seated the flared base flush against her body.
Instantly, the constant welling pressure deep in her transformed bladder surged, trapped. A low, desperate groan vibrated in Selina’s chest, muffled by steel and vibrating flesh. She felt impossibly full, plugged at both ends now – her mouth forced wide around her cock, her cunt gaping and empty but aching, her urethra sealed, the pressure building relentlessly behind the cold steel plug. Her eyes, wide and wild above the gag, met Dick’s amused blue gaze.
"Now we play," Dick said softly, his hand closing around the humming, steel-caged length of her clit-cock, squeezing hard. "Let's see how much your new tank can hold before it bursts." He started to stroke, the vibrations amplified by the steel ring. Jason’s slick fingers found her gaping, dripping cunt, two, then three plunging back in to the hilt. The pressure inside her swelled, a trapped tidal wave. The camera’s red light watched, unblinking.
