Chapter 19: Chapter 19
The antiseptic tang of the chamber cut through the lingering musk of their previous exertions. Zatanna lay supine on the reinforced medical gurney Bruce had wheeled into the central space of the dungeon, replacing the plush bed. Cold air kissed her flushed skin, making her nipples peak into tight, dark buds against the warm red glow of the overhead lamps. Restraints held her wrists and ankles to the cold steel frame, wide enough to grant access, secure enough to render her utterly open. Excitement thrummed alongside the low hum of the Batcave’s machinery deep below.
Bruce stood beside her, silhouetted against the racks of gleaming instruments. He wore thin nitrile gloves, their clinical snap as he pulled them on sending a fresh wave of heat pooling between Zatanna’s thighs. His face, usually Batman’s granite mask, was softer here, focused, intensely present. His eyes, sharp as ever, cataloged her nakedness with a scrutiny that made her squirm, not from shame, but from a desperate, swelling pride. He’d bathed her earlier, meticulously soaping every curve, rinsing her clean of their earlier sweat and slick. Now, she felt like a specimen laid out for his sole, rapt attention. His perfect patient.
"Subject exhibits pronounced vasocongestion," Bruce stated, his voice a low, resonant monotone that vibrated straight to her core. He picked up a sleek digital caliper. "Marked engorgement of the labia majora and minora. Significant tumescence noted." The cold steel of the caliper pressed gently against her outer lips, measuring. Zatanna gasped, her hips lifting involuntarily. "Oh, god, Bruce… seeing you measure me…"
"Quantifiable response to stimulus," he noted, the caliper clicking softly as he recorded a number on a nearby holoscreen. "Labial separation increasing. Excellent tissue turgor." He moved the instrument, the cool metal parting her slick folds slightly, grazing her inner thigh. "Clitoral glans fully exposed. Diameter increasing under observation." He measured the swollen nub of her clit, the slight pressure making her cry out, her body arching against the restraints. "Fuck! Yes! Measure it… measure how hard it is for you…" Her voice hitched.
"Clitoral diameter: 10.2 millimeters. Hyperresponsive." He set the caliper down and picked up the device she’d been anticipating with a mixture of dread and fierce need: the polished steel ring, about four inches across, fitted with six tiny, precise alligator clamps set equidistant around its inner circumference. "Proceeding with application of labial retractor."
The cold metal touched her outer folds first. Bruce worked with practiced, detached efficiency, yet his gaze burned. He gently pulled one plump inner lip, stretching it taut, and attached one of the tiny clamps to its very edge. A sharp pinch, then a dull, spreading ache of possession. Zatanna moaned, long and low. He repeated the process, stretching and clamping the opposite inner lip. Then, he pulled her outer lips wide, exposing her completely, the clamps biting gently but unyieldingly into the sensitive flesh, attaching them to the ring. With two more clamps, he secured her outer folds to the ring, pulling her entire cunt obscenely open, stretched wide like a glistening flower forced into bloom.
"Retractor secured," Bruce announced, his voice rougher now. "Vulva fully everted. Introitus and clitoris fully accessible for examination and stimulation. Subject displays copious vaginal lubrication." He ran a gloved finger along her drenched slit, gathering moisture. "Lubricant viscosity: high. PH optimal." He held the wet finger up, the purple light catching the sheen. "Fucking hell, Bruce," Zatanna panted, feeling utterly exposed, gloriously vulnerable, her cunt clenching around nothing, dripping onto the sterile pad beneath her. "Can you see everything? Do I look… perfect for you?"
"Optimal presentation," he confirmed, his gaze fixed between her legs. "Tissue coloration: deep erythema indicative of high arousal state. Clitoris engorged, glans fully erect." He picked up the implement Zatanna both craved and feared: the soft, supple leather tawse, split into two tails, its surface butter-soft but with a latent, stinging potential. He held it up. "Commencing test of clitoral reflex response. Pain threshold nominal."
He didn't hesitate. The first tap of the soft leather tails landed directly on her exposed, throbbing clit.
Fwip.
It was more sound than impact at first, a whisper of leather on hyper-sensitive flesh. A jolt of pure sensation, sharp and bright, lanced through Zatanna. "Ah! Oh!" Her back arched, her toes curled. Not pain. Not yet. A shocking, electric spark of pure, unfiltered feeling.
"Immediate, localized fasciculation observed," Bruce narrated, his voice tight. "Clonic contraction of pelvic floor musculature. Increase in respiratory rate." Fwip. Another tap, slightly firmer, landing on exactly the same spot. The spark flared into a wave of heat. "Nnngh! Bruce!" Her clit pulsed violently under the soft leather, the sensation radiating outwards, making her nipples ache and her asshole clench.
"Subject vocalization noted. Pupillary dilation significant. Continued clitoral engorgement: +0.3mm." Fwip. Fwip. Two quick, light strikes. Zatanna whimpered, her hips bucking uselessly against the restraints. The sting was there now, a bright, hot counterpoint to the deep, building pressure in her core. It wasn't hurting her; it was waking her up, stripping every nerve ending bare. "Ohgodohgod… it’s… it’s so much…"
"Sensory overload initiating," Bruce stated, watching the tiny, helpless tremors wracking her stretched pussy lips, the way her clit visibly jumped with each impact. His own arousal was a thick bulge straining against his pants, but his focus remained utterly on her, on her body's raw, exposed truth. Fwip-thwack! A slightly harder stroke, the tails spreading the impact just a fraction. Zatanna shrieked, a high, breathy sound. Her vision swam. Wetness gushed from her hole, pattering onto the pad. "Yes! Fuck! More! Spank it! Spank my big clit, Bruce! Make it take more, it's so goooood!"
"Noted: reflexive lubrication surge. Autonomic response overriding voluntary control." His voice was guttural now. He shifted stance, drawing the tawse back further. THWACK! A deliberate, stinging blow landed squarely on her engorged little nub. The pain was real this time – a bright, white-hot sting that vanished almost instantly, replaced by a tidal wave of pure, mind-melting pleasure that crashed through her pelvis. Her body went rigid, a silent scream on her lips. "Clitoral stimulation intensity at threshold. Orgasm imminent."
He didn’t let up. THWACK! THWACK! THWACK! Three rapid, consecutive strokes, each landing perfectly on her fat, exposed clit. The sensation blurred, vanished, drowned under an ocean of sensation. It was too much, too intense, a relentless assault on her very core. Zatanna’s head thrashed side to side on the gurney. Her eyes rolled back completely, showing only the whites, her mouth falling open in a soundless, gaping 'O'. Saliva slicked her chin. Her back arched impossibly high, every muscle locked in ecstatic rigor. No scream came, just a desperate, ragged sucking of air.
"Ahegao presentation confirmed," Bruce rasped, his clinical terms dissolving into pure reverence. "Full orgasmic seizure. Tonic-clonic phase initiated."
Inside, Zatanna shattered. Not just her body, but her mind. There was no thought, no identity, no magic, no Batcave. Only pure, white noise and the universe exploding through her clit. Her cunt convulsed violently, a series of hard, rhythmic spasms that had nothing to do with penetration, everything to do with the nerve center Bruce was relentlessly flogging into submission. Gush after hot gush of fluid surged from her opening, soaking the pad, dripping down her clamped-open labia, running in rivulets over her asshole. It felt endless, a geyser of pure, mindless release triggered by the sting and the stretch and his voice and his eyes on her absolute vulnerability.
Finally, the world slammed back. The convulsions subsided into violent tremors. Her vision cleared, blurred with tears, to see Bruce standing over her, the tawse hanging loosely at his side. His eyes were dark, intense, filled with a possessive awe that stole her breath all over again. Sweat plastered her hair to her temples. She was a wreck. An open, sopping, trembling wreck, her clit still throbbing like a raw, exposed nerve under the cold air.
"Do it again," she slurred. "Love it... Love you. Measure me. Spank my big clit. Is it good?"
His thumb a raced a slow, impossibly tender circle around the hypersensitive nub, making her whimper. "Optimal responsiveness, Zee," he breathed, leaning down, his lips brushing her sweaty forehead. "Optimal presentation. Optimal… surrender. Utterly perfect." He just looked at his handiwork – the reddened, stretched lips, the glistening, swollen clit, the mess she’d made. "My perfect patient." He buries his face in her cunt, sucking the fat throbbing pearl.
Bruce’s mouth sealed over her swollen, throbbing clit, the sudden heat and suction wrenching a ragged shriek from Zatanna’s raw throat. His tongue lashed the hypersensitive nub in furious, flat strokes, mimicking the tawse’s earlier sting, but wetter, deeper. She bucked wildly against the restraints, her clamped-open cunt gushing fresh slickness directly onto his chin, her cries dissolving into breathless whimpers. "Oh FUCK! Your mouth! Sucking my clit… sucking it!" Her hips pistoned, seeking more pressure, more friction against his relentless mouth.
He pulled back just enough, his breath hot and ragged against her soaked folds. "Show me how greedy you are, Zee," he growled, his voice thick with her taste. "Beg for the spanking while I eat your perfect cunt." His thumb found her clit again, already pulsing violently from his mouth. He didn't circle it tenderly now. Fwip. Fwip. Fwip. He spanked it sharply with the pad of his thumb, three quick, stinging flicks directly onto the engorged glans. Each impact sent jolts of electric pleasure radiating through her pelvis, making her inner walls clench rhythmically around nothing.
"YES!" she screamed, her back arching clear off the gurney. "Spank it! Spank my big fucking clit while you eat me! Make it take it! Oh god, it feels so good, it feels so huuuuge." Her words tumbled out, filthy and desperate. Bruce buried his face back between her splayed thighs, his tongue plunging deep into her dripping hole this time, fucking her with it, while his thumb kept up the rapid-fire assault on her clit. Fwip. Fwip. The dual sensation was overwhelming – the deep, wet invasion of his tongue stretching her entrance, the sharp, bright sparks exploding from each thumb-spank on her clit. Her vision whited out. "I'm cumming! Bruce! Cumming on your tongue! NOW!"
Her orgasm hit like a sledgehammer. She didn't just come; she erupted. Her cunt convulsed in violent, gushing spasms around Bruce’s thrusting tongue. Fluid surged out of her, drenching his face, his neck, soaking the collar of his undershirt. Her cries became guttural, animalistic groans as her body locked in ecstatic seizure, her eyes rolling back completely, jaw slack, saliva slicking her chin – pure, obliterated ahegao. Bruce drank her down, his tongue working frantically against her spasming walls, swallowing her release as her hips jerked uncontrollably against his mouth.
He didn't stop. As the first brutal crest began to subside, leaving her trembling and gasping, he pulled his mouth away, glistening with her slick. He reached for the soft tawse lying beside her thigh. Her eyes, unfocused and wet, tracked the movement. "No... please... sensitive..." she whimpered, but her clamped-open cunt visibly pulsed, dripping fresh arousal onto the soaked pad. Anticipation warred with overstimulation on her flushed face.
"Shhh," he murmured, the sound dark velvet, utterly at odds with the sting of the leather. "Your clit needs it, Zee. See how fat and red it is? Begging for the leather." He held the tawse poised above her glistening, swollen nub. "Beg me to make it sing." Her breath hitched. The memory of the sharp bliss it delivered warred with the raw sensitivity. "Fuck... please, Master... please spank it. Tawse my big clit... make it come harder..." Her voice was a broken whisper, thick with surrender and desperate need. "Need it... needs the kisses. Clit is made for kisses..."
He groaned. It was. He'd make it stand up for the kisses he'd give it.
THWACK. The first stroke landed dead center on her exposed clit. Not hard. Precise. The soft leather kissed the hypersensitive flesh, igniting a fresh firestorm. Zatanna bucked, her body bowing violently, but this time, it wasn't just shock. It was pure, unadulterated ecstasy tearing through her nerve endings. THWACK. Another. Her mouth fell open again in that silent scream, eyes rolling back, tears streaming – ahegao seizing her features once more, harder, more abandoned than before. "My clit. Bigger! Bigger, make it glow. Bruce, Bruce, ungh, angh, angh!" she wailed.
THWACK. THWACK. THWACK. Bruce laid down a rapid, rhythmic cadence with the tawse, each stroke landing perfectly on her engorged clit. He wasn't punishing. He was orchestrating. Tender care laced every sharp kiss of the leather, knowing exactly how much sting she craved, how much she could take before tipping into too much. It was pure sensation overload, relentlessly driving her higher. Her body convulsed not from one orgasm, but from a cascading series of contractions ripping through her core. "Unnngh! Ah! AH! FUCK! CUMMING! CUMMING AGAIN!" she sobbed, each word punctuated by the THWACK of the tawse and another violent clench of her cunt, spraying droplets of fluid with each spasm. Her mind dissolved into white noise, utterly consumed by the relentless firestorm Bruce was coaxing from her swollen, punished clit. He watched her break, stroke by stroke, his own need a tight knot in his gut, commanding her through the storm. "Take it. Take every stroke. Your clit belongs to the leather. Cum for it. Cum hard."
The tawse hung poised above her glistening clit, Bruce’s knuckles white on the handle. Zatanna’s breath hitched, her entire focus narrowed to that throbbing, exposed nerve. "Beg me," he commanded, the words vibrating in the sterile air. "Beg me to make it sing." Her clamped-open cunt pulsed, dripping fresh slickness onto the soaked pad beneath her hips. "Please, Master," she whimpered, her voice cracking, eyes locked on the leather tails. "Tawse it... spank my big fucking clit... make it glow... make it scream... need it... needs your kisses..."
Fwip-thwack!
The soft leather tails landed dead center, a precise, stinging kiss igniting fresh fire along every nerve. Zatanna’s body jackknifed, a silent scream tearing through her as pure ecstasy detonated. Her vision whited out, eyes rolling back instantly, jaw slackening. Drool slicked her chin. Fwip-thwack! Fwip-thwack! Bruce laid down a rapid, rhythmic cadence, each stroke landing perfectly on the swollen, hyper-sensitive nub. Not punishing. Orchestrating. "That's it," he growled, watching her face contort in abandoned ahegao, tears streaming. "Take it. Your greedy clit lives for this leather. See how it swells? Darker, harder." Her hips jerked erratically against the restraints with each impact, her cunt clenching rhythmically around nothing, spraying droplets.
He paused, the sudden absence of sting almost worse. Zatanna whined high in her throat, her body trembling violently on the precipice. Bruce tossed the tawse aside with a soft clatter. His gloved fingers, slick from her earlier gushes, slid effortlessly into her dripping hole. He curled them, finding that spongy ridge deep inside with unerring accuracy. "Deep tissue stimulation," he murmured, his voice thick. "Targeting the Grafenberg zone." He pressed firmly, rubbing in slow, deliberate circles. Zatanna gasped, her back arching sharply off the gurney. "Oh FUCK! Bruce! There! Rub it... rub my spot... make me gush!"
He did. His fingers worked her G-spot with relentless pressure, the internal massage sending thick waves of liquid heat flooding her core. Her clamped-open labia quivered. Her clit, still buzzing from the tawse, throbbed obscenely, engorging further under the dual assault. "Copious lubrication surge," Bruce observed, his gaze fixed between her legs. "Clitoral engorgement increasing... 11.3 millimeters... remarkable vascular dilation." He withdrew his fingers, glistening. "Open." Zatanna obeyed instinctively, mouth slack. He pushed the large, smooth silicone ball gag between her teeth, buckling it securely behind her head. Her muffled moan vibrated through the gag, eyes wide, pupils blown. Safe. Free to lose herself completely.
He picked up the tawse again. Her muffled cry was pure anticipation. Fwip-thwack! The leather kissed her clit again, the sting sharp and bright against the deep, internal ache his fingers had stoked. She arched violently, her scream trapped behind the gag, eyes rolling back, drool soaking her chin and neck. Bruce watched, mesmerized, as her face contorted into pure, unfiltered ecstasy – jaw slack, tongue pressing against the gag, eyes vacant pools of white. Perfect ahegao. He rubbed her G-spot again, deep and slow, feeling her inner walls ripple and clench around his fingers. "Feel that?" he rasped, his own control fraying. "Feel how your cunt creams when I rub deep? How your clit swells thicker, darker, begging for the sting?" Fwip-thwack! Another precise stroke. Her body convulsed, a fresh gush of fluid soaking his wrist. "Look at it," he commanded, his voice rough with awe. "Look at your perfect magic cunt, Zee. Wide open. Dripping. Taking every fucking thing I give it. Your clit... fuck... see how it stands up? Takes its spanking like it was made for it. Takes the teasing... the tawsing... and just gets fatter... redder... hungrier."
He alternated relentlessly: three sharp, stinging kisses of the tawse on her hypersensitive clit, followed by deep, grinding pressure on her G-spot, rubbing until fresh slickness poured from her stretched opening. Then back to the leather. Each cycle drove her higher, the sensations blurring into an unbearable crescendo. Her muffled screams behind the gag were constant now, high-pitched and desperate. Her body was a taut bowstring, trembling violently, sweat sheening her skin. The ahegao was permanent, her face a mask of drooling, tear-streaked ecstasy. "Cum for it," Bruce growled, landing another fwip-thwack directly on the engorged peak. "Cum harder than you ever have. Show me how your clit earns its spanking. Cum now!"
The command shattered her. Her body locked in a rigid arc, every muscle straining against the restraints. A silent, seismic scream tore through her, visible only in the violent tremor that wracked her frame. Her cunt convulsed in brutal, gushing spasms, flooding Bruce’s hand, the pad beneath her, dripping onto the cold floor. Her clit pulsed violently under the leather’s lingering kiss, visibly darkening, capillaries straining. It was annihilation. Deeper than the countdown. More violent than the wand. Pure, mindless convulsions ripped through her, wave after wave, each one wringing another torrent from her core. Bruce held the tawse lightly against her throbbing clit, feeling the frantic pulse beneath the leather, watching her utterly wrecked face, her eyes rolled back, mouth agape around the gag, drool pooling. "That's it," he breathed, reverence mixing with dark satisfaction. "My perfect magic cunt. Taking it all. Cumming harder than ever." Her body finally slumped, boneless, trembling, utterly spent, the only sound her ragged, gag-muffled breaths and the soft drip of her release onto the floor.
