Chapter 5: Chapter 5
The Batcave lab’s sterile chill was a physical slap after the alley’s grime. Harsh white light reflected off polished steel surfaces, monitors casting shifting blue glows onto the restraints of the central table where Selina lay. Dick stood beside her, his profile calm, almost detached, as his long fingers meticulously wound thin, strong cord around the swollen base of Selina’s left breast. Already, the cold steel towers attached to her nipples stretched the tips tautly outward, the dark, engorged flesh pulled thin and straining. Her chest heaved with quick, shallow breaths, the bindings digging into the soft, expanded flesh beneath her breasts, pushing them up and out unnaturally, making the nipple torture even more prominent. A low, continuous whine vibrated in her throat.
Jason ignored her, striding to a secondary console. He slapped his palm on the comm activation panel. “Oracle. Patch me through to Red Robin. Priority.”
A beat, then Barbara Gordon’s crisp, slightly weary voice: “Patching. He’s in the Nest.”
The connection fizzed. “Red Robin. What’s cooking, Hood? Still babysitting the cat burglar?” Tim Drake’s voice was alert, laced with his usual dry curiosity, but underneath was the familiar thrum of excitement at a complex problem.
“Got a bio-mod question for your creepy little brain,” Jason growled, pulling the warm STHE-9 vial from his pocket. He held it up, the iridescent blue fluid swirling like trapped lightning. “Synth-Tissue Hydraulic Expander. STHE-9. Supposed to inflate clitoral tissue fast. Painlessly. We need to tweak it.”
“STHE-9?” Tim’s tone shifted instantly to focused intensity. Jason could almost hear the gears turning. “Chrome-tech futa market stuff. Nasty. Efficient. What’s the tweak?”
“Slower release,” Jason said, watching Dick begin binding Selina’s other breast with the same ruthless precision. Selina flinched as the cord tightened. “Make it swell slow. Over hours, maybe a day. Gradual. We need the little bitch to feel every millimeter of growth. Make it hypersensitive during the process.”
On the table, Selina moaned, a sound caught between pain and something darker. “N-no… slow? Please…” Dick’s hand smoothed over the bound curve of her breast, a mockery of comfort, his thumb brushing the stretched tip of her nipple. She gasped, hips bucking against the heavy straps pinning her waist and thighs.
“Hypersensitivity… gradual growth…” Tim murmured. Jason heard rapid keyboard clacks. “Yeah, possible. STHE-9 works by stimulating localized stem cell proliferation and angiogenesis plus temporary fluid retention. The carrier solution is key. We need to inhibit the rapid fluid influx modulator… maybe replace it with a time-release polymer matrix. I can cook that up. Won’t be painless though, not entirely. More like… a deep, relentless ache. A constant, building throb. Exactly what you want for teasing, right? Make her obsessed with her own fucking clit.”
“Perfect,” Jason said, a grim satisfaction warming him. “How fast can you brew it?”
“Got the base polymers here. Twenty minutes. I’ll synth the inhibitor and matrix. Send a drone.” More typing. “Need the injector specs? Micro-pump or diffusion needle?”
“Micro-pump,” Jason decided, eyeing the tiny, vulnerable bud peeking from Selina’s slick folds. Dick was leaning down now, his tongue tracing the very tip of her steel-elongated nipple. Selina cried out, arching her back as much as the restraints allowed. “Subcutaneous. Need precise control over the inflation rate.”
“On it. Drone en route to Cave Alpha delivery lock. ETA fifteen minutes with the formula and the modified injector head. Hood… this is for her? She asked for this?”
Jason watched Dick’s mouth close over the sensitive, stretched nipple tip, sucking gently. Selina sobbed, her thighs trembling violently. “Begged for it, Replacement,” Jason said flatly. “Wants it big. Wants it whipped like a cock. We’re just giving the greedy little slut exactly what she ordered. Hood out.”
He killed the comm and turned towards the table. The scent of Selina’s fear and arousal hung thick in the ozone-tinged air. Dick straightened up from her breast, a thin strand of saliva connecting his lips to her glistening, abused nipple. Her chest was a landscape of bound, swollen flesh and cold, cruel steel stretching her nipples into obscene points. Her pussy glistened, wetness soaking the table beneath her.
“Formula’s incoming. Slowed release. Extra ache,” Jason announced, his boots echoing on the metal floor as he approached. He stopped at the foot of the table, looking down at Selina’s splayed legs, her puffy lips, the tiny, hard clit standing stiff and flushed against its hood. He tapped it lightly with the cold vial. She shrieked, jerking against the restraints. “Seems the cold tower treatment got you nice and sensitive down here too, kitty. Ready for your upgrade?”
“No! Jason, please!” Selina gasped, tears welling in her eyes. “Not slow… not that… it’s too much!”
Dick moved to her side, his hand sliding down her bound torso, fingers tracing the edge of her pelvic bone before dipping low to cup her mound. His thumb rubbed slow, firm circles dangerously close to her clit. She whimpered, trying to twist away, but the restraints held her fast. “You had plans, Selina,” Dick murmured, his voice dangerously calm. His thumb pressed harder, making her cry out. “Detailed plans. With Chalcedony and Alabaster. You commissioned a very specific transformation.”
Jason leaned forward, bracing his hands on the table near her hips. He locked eyes with her, his gaze boring into hers. “Let’s talk about your little cocklet fantasy, thief. Word for word.” His voice dropped to a low, gravelly threat. “Tell us what you said. What you begged them to do to it.”
Panic flared in Selina’s eyes. She shook her head frantically, sweat dampening her temples. “I… I don’t… it was just talk! Fantasy! I didn’t mean it!”
Dick’s thumb stopped circling. It pressed down directly onto her clit, hard. Not rubbing. Just relentless pressure. Selina screamed, her whole body straining, her back arching off the table. The steel towers pulled her nipples impossibly taut. “Ah! Dick! Stop! Please stop!”
“You’re lying,” Dick said evenly, not easing the pressure. “Chalcedony played it back. Verbatim.” His other hand drifted to her bound breast, fingers tightening around the swollen flesh just below the steel tower, squeezing. “You begged them to stretch it. To tape it down. To whip it with a tawse. To flog it.” He leaned down, his lips brushing her ear as his thumb ground into her clit. “You said you wanted to watch it bounce when it’s flogged.” He mimicked Chalcedony’s synthetic purr perfectly. “Such filthy, specific desires. Own them, Selina.”
Jason reached out, his calloused fingers replacing Dick’s thumb on her clit. His touch was different – rougher, more demanding. He pinched the tiny bud hard between thumb and forefinger and pulled outward, stretching the hooded skin. Selina shrieked again, a raw, broken sound. “How big, Selina?” Jason demanded, twisting slightly. “How big do you want your little cocklet to get before we whip it raw? Tell me the fucking truth, or I’ll start pumping now and we’ll find out your limit the hard way.”
Tears streamed down Selina’s face, mingling with sweat. Her chest heaved. The combination of the relentless nipple stretch, the crushing breast bindings, and the brutal pressure on her clit was overwhelming. Humiliation warred with a terrifying, unwanted spike of arousal. “I… I wanted it…” she choked out, gagging on the words. “I wanted it… big. Obvious.”
“How big?” Dick prompted, his hand still a vise on her breast. “Bigger than your thumb? Your finger?”
Jason twisted the clit again. “Fucking say it!”
“Big!” she screamed, her voice breaking. “As big as… as it can get! Stretched… long and thick! Like… like…” She sobbed, shuddering. “Like a little cock! Just a small one! But… prominent! Hard!”
“And the tape?” Jason growled, releasing the pinch but keeping his fingers splayed possessively over her mound. “You wanted it taped down?”
“Yes!” The word was a ragged gasp. “Tight! Against my slit! So it sticks out… so it can’t hide! So… so everything hits it!”
Dick’s hand finally eased slightly on her breast. He traced the red marks left by the bindings. “And the punishment? The tawse? The flogger?”
Selina squeezed her eyes shut, fresh tears leaking out. Her hips gave an involuntary, shameful little thrust against Jason’s restraining hand. “Yes,” she whispered, the sound thick with self-loathing and desperate need. “I… I wanted the sting. On the head. The… the glans. Sharp. Deep. I wanted… I wanted to feel it through the whole thing when it was hit.” She swallowed hard. “And… and to see it move. When the blows landed. To see it… bounce.”
Jason let out a low, dark chuckle. He looked at Dick. Dick’s blue eyes, usually so composed, held a chilling spark of satisfaction. He nodded almost imperceptibly.
A soft chime echoed through the lab. A drone whirred into view, hovering near the delivery hatch.
Jason pushed off the table. “There’s our kit. Right on time.” He walked to the hatch, retrieved the small, sterile case, and opened it. Inside lay a vial of modified, deeper blue fluid and a gleaming micro-injector with a fine, needle-like pump head. He loaded the injector with eerie efficiency, the fluid glinting ominously in the lab light.
He returned to Selina’s splayed legs. Dick stepped back slightly, giving him space, but his presence was a wall of calm intensity.
Jason held the loaded injector up, the tip gleaming. Selina stared at it, eyes wide with primal terror. “No,” she breathed. “Please, Jason… not slow… it’ll drive me insane…”
“Exactly the point, kitty,” Jason said, a feral grin spreading across his face. He placed his free hand firmly on her pubic bone, pinning her pelvis flat. With the other, he brought the injector needle down, positioning it precisely against the tiny, exposed base of her clit. “Hold her,” he ordered Dick.
Dick’s hands clamped down on her hips, holding her immobile. His thumbs dug into the crease where her thighs met her body. There was no escape.
Jason pressed the injector head against her tender flesh. He activated the pump. A low, almost inaudible whir filled the sudden silence. Selina held her breath, eyes locked on the device.
Nothing happened immediately. Then, a deep, intrusive pressure began to build at the very core of her clit. Not sharp. Not yet. A relentless, internal filling. A slow, inevitable expansion from the inside out. The deep ache Tim promised. It radiated outwards, a throb that echoed the unnatural stretch in her nipples and the tight confinement of her breasts.
“Oh… god…” Selina moaned, her voice trembling. She could already feel it. The tiny bud felt heavier, denser. The nerves, hypersensitive from Dick’s earlier clamp, screamed at the internal invasion. It didn’t hurt sharply. Not like the pinch. This was worse. It was a promise of relentless change. Of growth she couldn't stop. A slow-motion transformation into the exposed, punishable cocklet she’d fantasized about.
Jason watched her face, the cruel satisfaction deepening as he saw the dawning horror and the treacherous flicker of arousal warring in her tear-filled eyes. The pump whirred on. Filling her. Stretching her. Building the instrument of her own torment, millimeter by agonizing millimeter. The tape, the whip, the flogger… they were coming. And her body, reshaped by her own confessed desires, would be fully, exquisitely prepared to receive them. Her training had truly, irrevocably begun.
The Batcave lab hummed, sterile light reflecting off Selina’s sweat-slick skin as Dick’s fingers cinched the final knot on her breast harness. The cold steel nipple towers pulled her tips obscenely taut. Jason watched, the micro-pump injector a cold weight in his hand, its whirring filling the silence as Selina whimpered, feeling the slow, deep ache bloom in her clit. "It... it burns inside," she gasped, hips straining against the restraints.
Dick leaned close, his voice a low murmur beside her ear, cutting through her distress. "Tell us, Selina. What do you want? Right now. Be explicit."
Her breath hitched. The relentless internal pressure mixed with Dick’s proximity, the memory of her own filthy confessions hanging in the air. "I... I want it pumped," she choked out, shame warring with the undeniable heat coiling low in her belly. "I want it big. Like I told them. Please..."
Jason moved like a shadow. He set the injector aside and knelt by the table, his calloused hand surprisingly gentle as it smoothed up her inner thigh. He pressed a soft, lingering kiss just below her hip bone. "That's it, good kitty," he rumbled, the unexpected tenderness making her shiver violently. "Honesty gets rewarded." He kissed higher, closer to where the slow transformation throbbed. "We will give you everything you asked for, sweetheart. And so, so much more." He nuzzled the crease of her thigh. "But you gotta keep talking. Give us the filthy details. What did you dream about?"
Dick’s thumb found her swollen clit, already noticeably fuller, the hood stretched tighter. He applied the faintest, maddening pressure. "Tell him, baby. Tell us how you wanted it." Selina cried out, the dual sensations – Jason’s lips, Dick’s thumb – shattering her resistance. "I wanted it huge!" she gasped, the words tumbling out. "A fat, greedy little cocklet! Sensitive as hell! I wanted to feel every fucking touch like lightning!" Dick rewarded her with a slow, deliberate circle around the engorged tip. She sobbed. "Yes! Kiss it! Please! Kiss it while I'm being filthy!"
Jason obliged instantly. He shifted, replacing Dick’s thumb with his mouth, sealing his lips over the swollen, hypersensitive bud and sucking gently. Selina screamed, back arching off the table, the steel towers pulling cruelly at her nipples. The sensation was overwhelming – not just pleasure, but a terrifying, electric vulnerability. "Christ, it's sensitive!" she wailed. "Always was! Too small, too fucking receptive! Always on edge!"
Dick stroked her bound flank. "And when it's big?"
"Stronger!" she panted, Jason’s tongue flicking relentlessly. "I can... I can take the pleasure then! All of it! Even when it's too much! I'll cum so hard I'll black out!" The image of ecstatic surrender fueled her confession. "Yes! Big! Biggest clit! Sensitive enough that just pumping it... just the fucking pump sucking on it... makes me see stars! Ecstasy!"
Jason lifted his head, her clit glistening, visibly larger than minutes ago. "Full strength aphrodisiacs, like Chalcedony planned?" he asked, voice thick.
"Full strength," Selina begged, eyes wide and desperate. "Dump it in! Clit, tits, everywhere! Make me fucking rabid!" Dick captured her mouth in a deep, claiming kiss as Jason retrieved a new vial from the drone case – Tim’s modified serum, deep indigo and potent.
Jason prepared the injector, the needle glinting. "Special design, just for you, kitty," he said, aligning it not just with her clit, but also pointing towards her bound, straining breasts. "You begged. You get it." He plunged the needle into the base of her engorging clit. Selina shrieked, a sound of pure sensation, as the cold fire of the concentrated aphrodisiac flooded the tissue, amplifying the existing ache into a roaring, molten throb. The pump whirred again, pushing more volume. "Oh fuck! Fuck yes! Right there!" she babbled.
Jason withdrew, swiftly reloading. He injected directly into the swollen flesh of each bound breast, the serum burning a path through her mammary tissue. Tim’s formula worked fast. Selina gasped as her breasts seemed to swell beneath the harness, the leather straps biting deeper, the pressure immense. Dick and Jason’s hands were on her immediately, not punishing, but massaging firmly, almost lovingly, kneading the expanding flesh, working the serum deeper. Tim appeared at the edge of her vision, holding a small, soft flogger with thin suede falls.
"Feedback loop initiated," Tim stated clinically, but his eyes were bright. He brought the flogger down gently on Selina’s left breast. Thwap. The soft impact resonated through the hypersensitive, engorged tissue, not pain, but a shocking wave of sensation. "Ah! Oh god!"
Dick kissed her temple. "See? Honesty pays, baby." Thwap. Tim landed a matching stroke on the right breast. Selina moaned long and low, her hips grinding air. The aphrodisiac was like liquid fire in her veins, the massage, the soft flogging, the relentless expansion – it was unbearable ecstasy. "They're... they're getting so tight," she whimpered, feeling her breasts strain against the harness.
Dick ran a possessive hand over the swollen curve. "Promised you, remember? Big as your pretty head, Selina. Round, perfect orbs. Full to bursting." He squeezed, milk already beading at the tips of the steel towers from the intense pressure and serum. "Engorged with milk just like you told Alabaster you wanted. Ready for spraying. Ready for sucking."
Jason leaned in, nuzzling her neck, biting gently. "Gonna rework this harness soon, kitty. Need more room for these magnificent tits. Make ’em jut out, big round boobs on display." He pinched a steel tower lightly, sending a jolt through her. "Permanently presented."
Selina tipped her head back, mouth open, tongue lolling slightly, beyond words, riding the chemical and sensory tsunami. Tim stepped forward, another hypo in hand, filled with a milky solution. "Growth catalyst booster. To lock in the size and sensitivity. Maximize lactation potential." He pressed it to her neck. Selina barely registered the pinch, lost in the roaring need, the feeling of her body transforming into the exposed, hyper-receptive plaything she’d confessed to craving. The harness creaked under the pressure as her breasts swelled further, the injector’s whir the soundtrack to her sighs.
