Chapter 22: Urethral Expansion
The milking pumps hissed, rhythmic suction pulling at Selina’s engorged nipples, drawing thick streams of milk into sterile collection chambers. Her breasts felt heavy, aching, the sensation a deep, insistent throb beneath the cool blue light of the Batcave medbay. Strapped to the examination table, legs wide in padded stirrups, she could see her reflection distorted in the curved, mirrored surface of the Bubble encasing her head and shoulders. Trapped. Watching.
Jason’s gloved fingers, slick with lube, probed the flushed, glistening folds of her pussy, spreading her wide. He held up a long, thin rod of polished steel, its tip bulbous. "Look at you," he murmured, his voice a low rasp that vibrated through the Bubble’s speakers. "Soaked fucking cunt begging for it… but daddy’s got plans for this greedy little fuckhole first." His thumb pressed firmly against the tiny, straining opening at the tip of her clit-cock, already slick with her own arousal and the remnants of the serum. It pulsed visibly under his touch.
Selina whimpered, a sound swallowed by the Bubble’s insulation. Her hips jerked involuntarily. "Jason… please…"
"Please what, kitten?" He tilted the rod, aligning the bulbous tip. "Please shove this sound deep into your needy peehole? Please stretch you wide?" He didn’t wait for an answer. With deliberate, relentless pressure, he pushed. The cool metal breached her urethra.
A gasp tore from Selina’s throat. Not pain – the spell saw to that – but an intense, shocking fullness. A stretching sensation deep inside her cock that radiated heat straight to her core. Her back arched off the table. "Oh god… oh fuck…"
"Feel that?" Jason twisted the rod slowly, watching her reflection intently. Her green eyes were wide, pupils blown black with arousal and disbelief. "Feel how fucking tight you are? Greedy little slut." He pushed deeper, inch by inch, the smooth metal sliding with obscene ease thanks to the lube and the magic. Her cock twitched violently around the intrusion. "Taking it… taking it like a fucking champ." He gave the rod another quarter-turn. Selina cried out, her thighs trembling. The milking pumps pulsed in time with her ragged breaths.
Through the Bubble’s mirror, she saw Dick approach. He held another sound, slightly thicker than the first. Jason didn’t pause. As Dick applied lube to the second rod, Jason withdrew the first one slowly, leaving her urethra gaping slightly, sensitized and empty for a fleeting second. Before she could even register the loss, Dick pressed the tip of the new sound against her opening.
"Easy," Dick murmured, though his eyes held the same focused intensity. He pushed steadily. The stretch was sharper this time, more pronounced. Selina hissed, her fingers clawing at the padded restraints. "Breathe, Selina. Just breathe." He slid it deeper, joining Jason in watching her body’s reaction – the frantic flutter of her stomach muscles, the way her swollen clit-cock pulsed around the metal invading it.
Jason chuckled, a dark, satisfied sound. "See how she opens up? Like she was fucking made for it." He picked up a third sound, noticeably thicker than the second. Dick withdrew his rod smoothly. Selina felt impossibly open, vulnerable, her urethra clenching around nothing. Then Jason was there, the cold, thicker metal pressing insistently. "Gonna fill you up, kitten. Gonna stretch this magic fuckstick wide open."
He pushed. Harder. Faster. Selina screamed, a sound of pure, overwhelmed sensation. The stretch burned, a delicious, impossible pressure deep within her cock. Her hips bucked wildly against the restraints. "FUCK! Jason! Too much… feels too much!"
"It’s never too much," Jason growled, twisting the rod brutally. "Not for you. Not anymore." He shoved it deeper, burying it to the hilt. Selina convulsed, her vision whiting out for a second. Milk sprayed from the pumps in erratic spurts. Her cunt gushed, soaking the exam table beneath her. "Look at that," Jason breathed, mesmerized by the violent clenching of her cock around the thick steel shaft. "Fucking beautiful."
Dick returned, holding not another sound, but a string of smooth, fat silicone beads, each larger than the last, glistening with lube. Jason slowly withdrew the thick sound. Selina’s urethra gaped, visibly dilated, pink and glistening. Dick pressed the first bead against the opening. It was wider than the last sound. Selina whimpered, high and desperate.
"Deep breath," Dick instructed softly. He pushed. The bead stretched her impossibly wide, popping past the tight ring of muscle with a wet, yielding schlup. Selina gasped, her body arching violently. "One down." Dick pushed steadily, feeding the bead deeper inside her cock. The sensation was overwhelming – a thick, unyielding pressure filling her shaft. Then came the second bead. Bigger. Selina cried out, tears leaking from the corners of her eyes. "Two…" Dick murmured, his voice tight.
Jason watched, his gaze predatory. He picked up the thick sound Dick had used earlier. "Keep going," he ordered Dick. "Fill her up."
Dick pushed the third bead. Selina choked on a sob. The stretch was immense, bordering on unbearable, yet the magic held, transmuting potential agony into pure, mind-melting intensity. Her cock felt impossibly full, stretched taut. Dick fed the fourth bead in, then the fifth. Each one sank deeper, crowding her urethra, pressing against sensitive inner walls Selina never knew she had. She was panting, sweat slicking her skin, her entire being focused on the brutal, exquisite invasion of her cock.
Jason stepped forward, the thick sound slick and gleaming in his hand. Selina’s eyes, wide with panic and arousal, locked onto it in the mirror. "No… Jason… please… it’s too full…"
"Shhh," Jason soothed, the sound utterly at odds with the dark hunger in his eyes. He pressed the bulbous tip against her stretched opening, already occupied by the thick cord of beads disappearing inside her. "Daddy promised you’d cum on a sound." He pushed. The tip pressed against the taut ring of muscle stretched around the beads. He applied steady, unrelenting pressure. Selina screamed, a raw, ragged sound. Her body strained against the restraints, every muscle locked. The tip breached, forcing its way alongside the beads, stretching her urethra impossibly wider. Metal slid against silicone, deep inside her cock.
Jason pushed it deeper, inch by torturous inch, twisting slightly. The combined fullness – the thick beads and the solid steel rod – was catastrophic. Sensation detonated through Selina’s pelvis. Her cunt clenched violently, gushing fluid. Her cock pulsed around the invaders in frantic, rhythmic spasms. "FUCK! FUCK! I’M CUMMING! OH GOD, CUMMING!" Her voice was a shattered scream. Milk jetted from the pumps in powerful streams. Her body bucked and writhed, consumed by a climax that felt less like pleasure and more like a seismic eruption tearing her apart.
Jason held the sound deep, grinding it slightly as she convulsed. "That’s it," he growled, watching her milk spray, watching her juices soak the table. "Squeeze that fucking sound. Milk those fat tits dry. Take it all, you greedy fucking slut."
The orgasm seemed endless, wave after wave crashing over her, each one wringing another gush from her cunt, another spurt from her breasts. She was a dripping, shuddering mess, held open and filled impossibly full. Slowly, agonizingly, the tremors subsided. She lay gasping, utterly spent, the thick rod and beads buried deep inside her cock a constant, heavy reminder.
Jason slowly withdrew the sound. The slide was almost as intense as the insertion. Dick began carefully pulling the string of beads out, each one popping free with a wet, sucking sound that echoed obscenely in the sterile chamber. Selina whimpered with each extraction, her body oversensitive and trembling.
As the last bead slipped free, leaving her gaping and empty, Jason leaned close to the Bubble, his breath fogging the mirrored surface near her ear. His voice was a dark promise. "Good girl. Rested up? Because that was just the warm-up. Next…" He trailed a gloved finger down the mirrored reflection of her gaping, dripping cunt. "...we stretch this greedy hole wide enough to swallow Gotham."
Jason’s gloved finger traced the obscene outline of her gaping urethra in the Bubble’s reflection. "See that?" His voice scraped raw against her oversensitive nerves. "Pretty little fuckhole already begging for more." Selina shuddered, the milking pumps pulling another thin stream from her aching breasts. Her cunt pulsed, empty and slick, anticipating violation. The serum’s hunger gnawed deep, a hollow ache demanding filling.
Dick moved silently, retrieving something from a chilled storage unit. The heavy thunk of dense silicone hitting metal echoed. He held it up: a monstrous Bad Dragon toy, thick ridges and bulging knots glistening under the sterile blue light. Its sheer size made Selina’s breath hitch. "Fuck no," she rasped, voice raw from screaming. "Jason… you can’t…"
"Watch me," Jason growled, taking the toy from Dick. He slathered thick, clear lube over its obscene girth. The scent of artificial cherries mixed sickeningly with antiseptic. He positioned the blunt, flared head against her dripping slit. The pressure was immense, immediate. "This greedy cunt swallowed sounds like candy. Think it can swallow this?" He pushed, just an inch, stretching her outer lips wide.
Selina cried out, her hips instinctively trying to arch away, restrained by the padded stirrups. The stretch burned, a delicious, impossible pressure. "Too big! Christ, it’s too fucking big!" Her clit-cock throbbed violently against her belly, flushed and swollen from its earlier torment. She watched its frantic pulse in the mirror, a traitorous beacon of her arousal.
"Bullshit," Jason grunted, applying relentless pressure. The thick ridge of the toy’s head breached her, forcing her open with a wet, yielding groan. Her inner muscles clenched furiously, trying to resist the impossible invasion. "Fight it all you want, slut. You’ll fucking take it." He leaned his weight into it, shoving another inch deeper. Selina gasped, her vision blurring. The sheer fullness was catastrophic.
Dick observed clinically, adjusting a monitor showing internal pressure readings. "Tissue integrity holding. Minimal stress." His detached tone was another violation. Jason chuckled, a dark rumble. "Told you. Magic fuckstick keeps her hungry and stretchy." He twisted the toy slightly, grinding the thick ridge against her inner walls. Selina whimpered, her cunt fluttering helplessly around the intrusion. "Feel those ridges, kitten? Gonna carve your greedy cunt into a perfect sleeve."
He pulled back slightly, then slammed forward, burying another few inches. Selina screamed, her body bowing off the table. The toy stretched her impossibly wide, the bulging knot still lodged terrifyingly outside. Milk sprayed erratically from the pumps. "FUCK! STOP! PLEASE!" Her plea was ragged, desperate. Her stuffed clit-cock pulsed in time with her frantic heartbeat, a beautiful, obscene display of forced submission.
"Stop?" Jason mocked, pausing, letting her feel every inch of the thick silicone splitting her open. "You don’t want me to stop." He gave the toy a vicious twist. "This hungry hole is sucking me deeper. Look at it!" He gestured at the mirror. Her cunt lips were stretched taut, shiny with lube and her own slick, clinging obscenely to the monstrous girth invading her. "Begging for that knot."
Tears tracked down Selina’s temples. "No… Jason… it won’t fit…" The denial was weak, swallowed by the serum’s relentless thrum demanding more. Her body betrayed her, inner muscles rippling, trying to pull the toy deeper. Her clit-cock stood rigid, dripping pre-cum onto her belly.
"It’ll fit," Jason promised, his voice thick with dark anticipation. He braced himself, gripping her hip hard. "Because you’re gonna fucking make it fit." With a brutal, grunting shove, he drove the thick knot against her straining entrance. Selina’s scream tore through the Bubble, raw and primal. Her body convulsed, fighting the impossible stretch. The knot pressed, stretched, burned.
Then, with a final, wet, tearing sound that echoed in the chamber, it popped past the tight ring of muscle. Selina’s vision whited out. The sensation was beyond anything – a brutal, complete filling, the massive knot locking deep inside her, stretching her cunt walls to their absolute limit. She hung suspended, impaled, breathless. Her stuffed clit-cock jerked violently, untouched yet achingly hard.
"Fuck yes," Jason breathed, mesmerized by the obscene bulge distending her lower belly. He gave the toy’s base a rough tug, testing the knot’s hold. Selina whimpered, oversensitive and impossibly full. "Look at that," he commanded, forcing her gaze to the mirror. "Look at your beautiful, stuffed cunt. Look at that magic fuckstick, still so fucking hard. Begging for attention."
He traced the thick base of the toy protruding from her stretched lips. "Greedy little whore took the whole damn thing." Dick nodded, checking the monitors. "Physiological responses optimal. Serum saturation increasing." Jason’s grin was feral. "Good. Now..." His hand closed around her throbbing clit-cock, slick with her own fluid. "...let’s see if we can make this greedy fuckstick squirt while she’s stuffed full." His thumb pressed hard against the slit. Selina’s gasp was pure, shuddering anticipation. The stretch inside her was agony and ecstasy, a brutal promise of more
Selina’s gasp was pure, shuddering anticipation. The stretch inside her was agony and ecstasy, a brutal promise of more. Jason’s calloused thumb pressed hard against the weeping slit of her clit-cock, sending electric jolts through her overstuffed core.
"Still so fucking hard," Jason growled, his grip tightening, making her shaft pulse visibly against her belly. "Like a little purple fist begging to be milked dry." He twisted his thumb, grinding the steel bead piercing into her hypersensitive tip. Selina shrieked, her hips bucking wildly against the restraints, the massive silicone knot lodged deep in her cunt grinding mercilessly against her inner walls. Milk sprayed erratically from the pumps still suctioned to her swollen breasts. "Fuck! Jason! Please!"
Dick moved with silent purpose, slicking his thick cock with a generous handful of chilled lube that gleamed under the sterile blue lights. The sharp, artificial cherry scent cut through the musk of sweat and sex. He positioned himself behind her, his gaze fixed on her asshole, already glistening and slightly gaping from the laser-spankers’ earlier attention. "Ready for the main course, kitty?" Dick’s voice was tight, strained with his own arousal. He pressed the broad, slick head of his cock against her tight rosette. The pressure was immense, immediate.
Selina froze, her breath catching. "Dick... wait..." The plea was weak, swallowed by the serum’s insistent thrum demanding fullness. Every fullness. Her body betrayed her, her asshole fluttering weakly against his cockhead, trying to yield. Jason chuckled darkly, a low rumble vibrating through her. "She’s fucking ready," he declared, his thumb still grinding her clit-cock. "Look at that greedy hole wink. Begging for Dick’s fat cock." He leaned closer to the Bubble, his breath fogging the mirrored surface near her ear. "Tell him, kitten. Tell Dick how bad you want his cock rammed up your ass while that monster stretches your cunt."
The humiliation burned, hotter than the stretch. Yet beneath it, the magic and serum fused, twisting the shame into a dark, irresistible craving. Her voice emerged, ragged but clear. "Shove it in... Dick... please... Stuff my ass... Stuff me full!" Her asshole clenched again, a desperate invitation. Dick didn’t hesitate. He pushed. Hard. The thick crown breached her tight ring, stretching her impossibly wide in a single, brutal shove. Selina screamed, a raw sound ripped from her throat, her body arching violently. The dual invasion – monstrous silicone knot deep in her cunt, Dick’s thick cock splitting her ass – was catastrophic. She felt stretched to breaking, filled beyond comprehension, her belly distended obscenely. "OH GOD! FUCK! YES! STUFFED!" she babbled, tears streaming freely.
Jason’s hand tightened like a vise around the base of her throbbing clit-cock. "Not yet, greedy girl," he snarled. "Interview time." A small red light blinked insistently on the camera lens mounted near the milking apparatus. "Look at the camera, slut. Tell them." He began a brutal, rhythmic pumping motion on her shaft, his fist sliding slickly over her hypersensitive flesh. "Tell them why you love being double-stuffed like a cheap whore."
Dick began to move, pulling his cock almost entirely out of her ass before slamming back in with deep, punishing thrusts. Each drive buried him to the hilt, grinding against the silicone knot bulging in her cunt from the other side. The sensations collided – the deep, grinding pressure in her cunt, the sharp, stretching burn in her ass, the rough friction on her clit-cock. Selina gasped, her vision swimming. The camera’s red light pulsed. "Because... because it wrecks me!" she cried out, her voice cracking. "Feels... feels like I’m being split... torn open...owned!" Dick’s thrusts intensified, the slap of flesh against flesh echoing in the Bubble. "They... they fill me... completely... no space left... just... just stretch... and burn... and..." Jason twisted his fist savagely around her cockhead. "And what?" he demanded.
"And it makes me feel... fucking used!" Selina shrieked, her body convulsing between their brutal ministrations. "Like a worthless... cocksleeve... made for stuffing!" Her words tumbled out, raw and unfiltered, fueled by the serum and the overwhelming violation. "Daddy’s fist... Dick’s cock... that monster toy... all wrecking me... filling every hole... stretching me... ruining me!" Dick grunted, his thrusts becoming shorter, harder, pistoning into her ass. "Fuck yes... ruin this ass... ruin Daddy’s greedy kitten!" Selina moaned, her hips trying desperately to meet his drives, impaled as she was. "Feels... feels so fucking full... like I’ll burst... but I need more... always need more!" Jason’s pumping hand became a blur, his thumb grinding relentlessly against her pierced tip. "Gonna make you squirt," he promised darkly. "Gonna make you gush all over this fucking sound while they wreck your holes."
The pressure built, a terrifying tsunami rising from her core. The knot in her cunt ground deep. Dick’s cock hammered her ass. Jason’s fist abused her clit-cock. The milking pumps pulled relentlessly. The camera watched. Selina’s world narrowed to white-hot sensation and the desperate need to scream her truth. "I LOVE IT!" she roared, her voice raw and shattered. "LOVE BEING DOUBLE-STUFFED! LOVE BEING STRETCHED! LOVE BEING RUINED! FUCK ME! WRECK ME! MAKE ME YOUR BROKEN SLUT!" Her body locked rigid. A guttural, inhuman sound tore from her throat as her cunt spasmed violently around the knot, her ass clenched viselike around Dick’s cock, and her clit-cock erupted. Not just cum, but a violent spray of clear fluid jetted from her slit, soaking Jason’s fist and her belly as her entire body was wracked by a convulsive, shattering climax that felt like her soul was being ripped out through her stuffed holes. Milk sprayed in thick streams. Dick roared, burying himself deep, his own release pulsing hot inside her ass. Jason held her cock tight, milking every last spurt, watching her break completely. The camera’s red light blinked steadily, capturing every twitch, every spasm, every drop. Selina collapsed back onto the table, gasping, dripping, utterly destroyed, the monstrous toy still locked inside her, Dick’s softening cock still buried in her ass. Jason slowly released her twitching clit-cock, slick with her spendings. He leaned close to the Bubble, fogging the mirror with his breath. "Good girl," he rasped, a dark promise in his eyes. "Now... let’s see how many fists that magic cunt can swallow."
