Chapter 8: Chapter 8
The cool silk settled over Zatanna’s eyes, plunging her world into profound, velvety darkness. Bruce’s fingers, deft and sure, secured the knot at the back of her head, the slight tug on her hair sending a shiver down her spine that had nothing to do with fear. "Three hours, beloved," his voice rumbled, low and intimate in the cavernous silence of the Batcave, punctuated only by the persistent, rhythmic hum of the machines attending to her body. "Safe. Free. Mine."
Her breath hitched. Deprived of sight, every other sense roared to life. The scent of aged leather, ozone from the computers, and the sharp, musky tang of her own arousal filled her nostrils. The chill of the steel restraints encircling her wrists and ankles was a stark counterpoint to the furnace heat radiating from her core. But most overwhelming was the relentless, dual penetration – the thick, unforgiving steel dildo pistoning deep into her cunt with mechanical precision, its twin counterpart stretching her asshole with each synchronized thrust. They were cold, yet the friction ignited sparks that raced along her nerves.
"Fuck, Bruce," she gasped, her head lolling back against the padded rest. "They feel... so fucking deep." The words were thick, slurred slightly by the intensity of sensation.
A soft click echoed near her breasts, followed by a sharp, delicious bite as Bruce reattached the vibrating nipple clamps. The sudden buzz sent jolts straight to her clit, already trapped and engorged within the clear cylinder of the milking pump. She cried out, her hips jerking futilely against the restraints holding her spread-eagled on the specialized gurney. "Ohgod! Yes! Right there!"
Bruce’s presence was a solid warmth beside her. She heard the soft rustle of fabric, the tap of keys on a nearby console. He was working, analyzing data streams projected onto unseen screens, yet his focus remained palpably on her. "Orgasm number three," he stated, his voice clinical yet layered with dark heat. "Initiated by clitoral stimulation combined with dual deep penetration. Duration: forty-two seconds. Marked by pelvic tremors and vocalizations escalating to a scream." He paused. "Your clit is visibly engorging further. Measuring at eighteen millimeters now. Responding beautifully to the suction."
The praise, delivered in that detached Batman tone, sent another wave of heat crashing through her. The pump maintained its steady vacuum pull, the sensation a constant, low thrum of exquisite torment centered on her most sensitive spot. Combined with the pistoning dildos and the intermittent buzz on her nipples, it created a symphony of overstimulation that kept her hovering on the knife-edge of climax without tipping her fully over again – yet. The steel rods slid in and out, slick with her juices, the wet, rhythmic sounds obscene and thrilling in the quiet cave.
"Tell me," Bruce commanded softly, his hand resting lightly on her trembling thigh. "Tell me what you crave, Zee."
She whimpered, straining against the bonds. The darkness amplified everything – the ache in her stretched holes, the insistent pull on her clit, the desperate need coiling tighter and tighter in her belly. "More," she begged, her voice ragged. "Bruce... please... I need... I need it more. Don't stop. Don't ever stop." She swallowed, forcing the words past lips gone dry. "I want... I want to feel like I'm breaking. Like I can't take another second... but you make me take it. Make me cum until... until I forget my own fucking name."
A low growl escaped him, a sound of pure, possessive satisfaction. She felt his fingers trace the swollen lips of her pussy, slick and hot, brushing against the base of the dildo plunging into her. "Breaking?" he murmured, his breath warm against her ear. "You're nowhere near breaking, my sorceress. You're thriving. Look at you." His fingers dipped lower, tracing the stretched rim of her asshole around the other invading steel. "Taking both so deep... your greedy little holes sucking them in. And this..." His fingertip tapped the cylinder encasing her clit. "Growing so big, so sensitive... just begging to be milked dry."
He straightened, the console keys tapping again. "Orgasm number four building. Elevated heart rate, increased vaginal lubrication, clitoral engorgement accelerating." His hand returned to her thigh, squeezing gently. "Give it to me, Zatanna. Scream it out."
The command, coupled with a sudden intensification of the nipple clamp vibrations and a fractional increase in the pump's suction, shattered her control. The orgasm ripped through her, violent and consuming. Her back arched violently off the gurney, every muscle locking tight as a silent scream tore from her throat before erupting into raw, guttural cries. "BRUCE! FUCK! YES! OHGODOHGODOHGOD!" Her cunt clenched spasmodically around the steel shaft buried inside her, her asshole pulsing, her trapped clit throbbing wildly against the relentless pull of the pump. Milky fluid, not just arousal, spurted into the cylinder – evidence of the relentless stimulation pushing her body beyond its usual limits.
He documented it all, his voice a steady counterpoint to her shattering cries. "Peak intensity achieved. Duration: fifty-eight seconds. Significant ejaculate volume recorded. Clitoral measurement now nineteen point five millimeters." As the waves began to subside, leaving her trembling and gasping, soaked in sweat and her own fluids, he leaned close again. "Beautiful," he breathed, his lips brushing her temple. "Utterly fucking beautiful. Just like I promised. Seven memorable... we're just getting started."
She whimpered, a broken, needy sound. The respite was agonizingly brief. The machines didn't relent. The dildos continued their deep, penetrating rhythm. The pump maintained its suction. The nipple clamps buzzed intermittently. The edge was still there, sharp and demanding, already beginning to build again beneath the aftershocks. "Please..." she sobbed, the word barely audible. "Don't... don't let it stop... Bruce... make me cum... make me cum forever... I need it... need to be... used... like this..."
He stroked her hair, his touch unexpectedly tender amidst the clinical machinery and her raw desperation. "Shhh," he soothed, though his next words were anything but gentle. "Forever is a long time, beloved. But three hours? That, I can give you." His fingers trailed down to trace the curve of her pregnant belly, a grounding, possessive touch. "Every scream. Every drop. Every millimeter you grow for me... I'm here. Watching. Documenting." He tapped the console again. "Building towards number five. Prepare yourself."
Zatanna shuddered, a fresh moan escaping her as the vibrations on her nipples intensified once more. Blindfolded, bound, filled, and relentlessly stimulated, she surrendered utterly to the sensation, to his control, to the terrifying, ecstatic promise of the next wave. The darkness wasn't empty; it was filled with him, with the machines, with the overwhelming certainty of pleasure pushed to its absolute limit. She tilted her head back, offering her throat, her body already tensing in anticipation of the next shattering climax he would meticulously draw from her depths. The countdown pulsed in her veins, synchronized with the pistons and the pump: three hours. An eternity of blissful torment. Just beginning.
A fresh moan escaped Zatanna’s lips, raw and hoarse from screaming. Her head rolled weakly against the padded rest. "Bru... need..." she slurred, the words thick with desperate lust. "Need... harder..."
Bruce’s shadow fell over her, a cool presence against her overheated skin. He leaned in close, his breath stirring the hair near her ear. "Shhh, beloved," he murmured, his voice rough with his own arousal. "You need to focus on taking what I give you." His hand rested momentarily on her belly, a possessive anchor. "No more begging incoherently. We need clarity for the data." His fingers brushed her sweat-slicked jawline, tracing down to her parted lips. "Open."
She obeyed instantly, her mouth opening in blind submission. The cool, smooth orb of the soft silicone gag pressed against her tongue. It was substantial but yielding, designed to fill without choking. She tasted faint rubber and cleanliness. Bruce guided it deep, the bulb settling firmly behind her teeth. He buckled the strap snugly behind her head, the leather cool against her nape. The gag muffled her next whimper into a low, throaty hum, her jaw comfortably stretched. Saliva pooled instantly. "Perfect," he stated, his thumb wiping a stray drop from her chin. "Long-term comfort ensured. Now, let's enhance the primary stimulus."
He moved down her body, his focus shifting to the milking apparatus clamped onto her swollen, throbbing clit. Zatanna strained against the steel restraints encircling her wrists and ankles, trying futilely to lift her hips, to fuck herself against the relentless suction. But the gurney held her immobile; she could only writhe and take it. The dual steel rods continued their deep, synchronized pistoning inside her ass and cunt, an unyielding counterpoint to the pull on her clit. Bruce tapped commands into the control panel beside the milker. A soft, deeper whir joined the cave’s ambient hum. The vacuum pressure increased dramatically, a powerful, insistent suck centered entirely on her engorged nub. He adjusted the articulated arm, pulling it taut until her clit stood upright, rigid and fully exposed within the clear cylinder, glistening under the cave’s dim lights, perfectly positioned for the overhead cameras recording every detail.
"Fuck!" The sound was swallowed entirely by the gag, emerging as a choked, desperate vibration in her throat. Her hips jerked violently, muscles straining against the bonds, but the milker held her clit immobile, sucking fiercely. Her swollen labia, still adorned with the vibrating clamps, pulsed against the cool cylinder. Bruce watched the monitor displaying her vital signs and the live feed of her straining sex. His free hand slid down his own body, unzipping his trousers and freeing his thick, rigid cock. He began stroking himself slowly, his gaze fixed on her displayed clit. His other hand rested warmly on her trembling thigh.
"Observe," he commanded, his voice detached yet thick with lust. "Subject exhibits involuntary pelvic thrusting against restraints. Significant increase in clitoral tumescence observed. Current measurement: twenty-two millimeters. Vascular engorgement pronounced. Vaginal lubrication secretion accelerated to maximum observed levels. Anal sphincter exhibiting rhythmic contractions corresponding with penetration cycle. Nipple erection sustained at maximum under clamp stimulus." He squeezed her thigh reassuringly as he continued his slow, deliberate stroking. "Physiological response indicates extreme arousal bordering on sensory overload. Subject remains safely within tolerance parameters. Vocalizations fully muted by gag." She moaned around the silicone, a sound of pure, overwhelmed bliss, her entire focus consumed by the brutal, glorious suction stretching her sensitive flesh.
Her clit pulsed visibly under the intensified vacuum, swelling further under the relentless pull, engorging beyond anything she’d felt before. It felt huge, impossibly sensitive, a throbbing focal point of raw sensation. Bruce watched it grow, his clinical demeanor momentarily cracking into pure, greedy hunger. "Jesus, Zee," he breathed, abandoning the monitor for a moment. "Look at that. Look how fucking fat and beautiful it is." He released his cock and moved swiftly. With practiced ease, he detached the current cylinder, the sudden release of pressure drawing a high-pitched whine from Zatanna’s gagged mouth. Her clit, freed for only a second, stood proud and flushed, glistening with her slick and slightly elongated from the suction. Bruce grabbed a larger, wider cylinder from the tray beside him. "Greedy little thing needs more room," he growled, his voice rough. He positioned the new cylinder and reactivated the pump. The wider mouth sealed brutally over her swollen nub and a significant portion of her hood, the suction slamming back with even greater force, drawing her distended flesh deep into its chamber.
He leaned down, his lips brushing her ear, his words a hot, explicit whisper that cut through the gag's muffling. "It’s fucking glorious, Zatanna. A perfect, fat, engorged little cocklet standing straight up, dripping for me. Pink and glistening, stretched so fucking tight. I can see every vein, every pulse. So goddamn pretty." His hand returned to her thigh, squeezing possessively. "I’m going to suck it raw when this is done. Worship it with my mouth until you scream. Then I'll clamp our heaviest weights onto it. Make it bounce while I fuck you senseless. It’s going to be the bullseye for every toy, every flick of my tongue, every greedy suck." The vivid image, combined with the overwhelming sensation of the larger cylinder devouring her clit and his filthy promises detonated inside her. She didn’t just cum; she squirted. A gush of clear fluid erupted from her cunt around the pumping steel dildo, splattering onto the gurney below, followed by violent, convulsive shudders that shook her entire frame. Her vision whited out behind the blindfold, a silent scream locked behind the gag as her swollen clit throbbed madly against the powerful vacuum, triggering wave after wave of excruciating pleasure. Bruce’s hand tightened on her thigh, grounding her through the storm. "Orgasm number five," he stated, his voice thick with satisfaction, returning to the clinical even as he resumed stroking his cock. "Triggered by explicit verbal stimulus combined with cylinder upgrade. Marked by high-volume female ejaculation and sustained full-body convulsions. Clitoral measurement now twenty-five millimeters. Proceed to documentation phase." He watched her shudder, utterly spent yet still trapped in the machine's relentless rhythm, knowing the next peak was already building.
Zatanna’s body convulsed, a final tremor racking her frame as the echoes of the fifth orgasm faded into trembling exhaustion. Sweat slicked her skin, gleaming under the Batcave’s cold lights. Her chest heaved against the restraints, each breath a ragged, muffled gasp around the thick silicone gag. The machines didn’t relent. The twin steel rods continued their ceaseless, deep thrusts into her cunt and ass, pistoning with mechanical indifference, stretching her holes obscenely wide with each pass. The wider cylinder encasing her clit maintained its fierce, unyielding vacuum, the powerful suction drawing her swollen flesh taut and deep, making it pulse like a frantic, trapped heart. Bruce watched the monitor, his gaze sharp, analytical, yet burning with dark intensity. “Response plateau,” he murmured, one hand resting possessively on her trembling thigh, the other still slowly stroking his own rigid cock. “Elevated arousal sustained. Clit holding at twenty-five. Requires additional stimulus for further growth.”
He leaned down, his lips brushing the shell of her ear, his voice a hot, rough whisper that cut through the cave's hum and her own muffled panting. “You hear that, my greedy magician? Twenty-five millimeters. Fat, beautiful, straining against that glass. But not enough.” His breath hitched slightly as he squeezed his cock’s base, his eyes fixed on the monitor displaying her engorged clit trapped in its clear prison. “I promised you thirty. Remember? Thirty fucking millimeters of pure, swollen need. I’m going to pump this desperate little cocklet until it’s thick and heavy, a perfect target.” His hand slid up her thigh, fingers tracing the edge of the cylinder where it sealed against her puffy labia. “Imagine how it’ll feel when I finally take this off. How heavy it’ll hang. How sensitive. How my tongue will worship every fucking vein, suck it raw until you’re sobbing.” He paused, letting the filthy image sink in. “Thirty, Zee. We’re getting there. Feel it grow for me.”
Her response was immediate, visceral. A low, desperate keen vibrated in her throat, muffled hopelessly by the gag. Her hips gave a futile jerk against the steel restraints. Inside the cylinder, the suction seemed to intensify with his words, a relentless pull that resonated deep into her core. Her clit throbbed violently, visibly engorging further under the combined assault of the machine and his explicit promises. Her cunt clenched hard around the invading steel shaft, fluttering rhythmically as fresh arousal slicked its path. Bruce’s eyes narrowed, watching the vital signs spike. “There it is,” he growled, his voice thick with satisfaction. “Verbal stimulus triggering physiological acceleration. Clitoral tumescence increasing.” He pressed a button, subtly increasing the suction pump’s power. The whir deepened fractionally. “Twenty-six.” He stroked himself faster, his thumb swiping over his leaking tip.
He leaned in again, his lips grazing her damp temple, his whisper dropping lower, rougher, dripping with obscene intent. “That’s it, baby. Give it to me. Swell up like the perfect little fuck-toy you are. Imagine it… thirty millimeters of raw, exposed nerve endings. I’m going to clamp it. Heavy steel weights pulling it down, making it bounce while I fuck your cunt raw.” His free hand drifted down to her belly, resting protectively over their child, a stark contrast to the filth spilling from his lips. “Then I’ll shove this cock down your throat, make you gag on it while the weights swing. Your fat clit begging for attention, dripping onto the floor.” He punctuated the image by giving his shaft a sharp, possessive tug. “Can you feel it stretching? Can you feel how fucking much I want it huge? Give me thirty, Zatanna. Now.”
It detonated within her. The explicit verbal assault, the ruthless suction, the relentless pistoning deep inside her ass and cunt – it fused into a white-hot spear of sensation. Her spine arched violently off the gurney, muscles straining against the unforgiving steel cuffs. A raw, guttural scream tore from her throat, utterly swallowed by the gag, emerging only as a choked, vibrating sob. Her cunt convulsed wildly around the dildo, fluttering in frantic spasms. Inside the cylinder, her clit pulsed like a frantic drumbeat against the powerful vacuum, swelling, stretching, engorging beyond reason. Fluid – slick arousal mixed with the distinctive milky evidence of relentless clitoral overstimulation – spurted into the chamber, coating the glass. Bruce watched, mesmerized, his hand moving furiously on his cock. “Orgasm number six!” he rasped, his voice strained. “Trigger: Explicit verbal degradation combined with peak suction. Marked by extreme vaginal convulsions and high-volume clitoral ejaculation!” He glanced at the monitor, a feral grin touching his lips. “Measurement: Twenty-eight millimeters. Significant growth observed.” He didn’t stop stroking, his gaze locked on her shuddering form. “Almost there, beloved. Almost thirty. Feel it? How much bigger it is? How much more there is to take?” He leaned close, his whisper a hot, relentless promise against her sweat-slicked skin. “Next peak pushes you over. I won’t stop until that number flashes thirty. You’re going to break that gauge for me.” Her body trembled, utterly spent yet vibrating with the machine's rhythm and the terrifying, ecstatic certainty of the next unbearable crest. His thumb traced the edge of the cylinder, feeling the heat radiating from her trapped, straining flesh. “So fucking close.”
