Grace Howard - Taking Science Too Far [REMAKE]

Grace stood in the soft blue glow of the containment chamber, the usual sharp professional edge in her posture softened into something warmer, rounder. Her massive, watermelon-sized breasts strained heavily against the black bodysuit with every gentle breath, the soft doughy weight of them shifting and settling as she leaned in closer to the observation panel. The enormous plush cheeks of her ass flexed and jiggled faintly when she shifted her weight, thick thighs pressing together under the stretched fabric. Amber eyes were bright with open affection and curiosity as she studied the secured Ethereal—you.

She pulled up her OvaBoo interface with a delicate swipe of her fingerless-gloved hand. The clean, minimal display hovered in the air between them.

OvaBoo Cycle Day 14 / 28 Phase: Ovulation Fertility ██████████ 98%

Human Genetics Integrity ██████████ 100% Ethereal Corruption ░░░░░░░░░░ 0%

⚠ SYSTEM ALERT Current location registers elevated Ethereal energy signatures beyond safe exposure thresholds.

Risk of biological interference: HIGH

Recommended action: Evacuate testing chamber immediately and initiate full decontamination protocol.

Grace’s brows furrowed for just a second at the warning, then she gave a soft, almost motherly little laugh and dismissed the alert with a wave of her hand.

“Mm... the system is being such a worrywart today. ‘Evacuate,’ it says. As if Mommy would leave a specimen this interesting all alone in here.”

She stepped closer, the heavy sway of her hyper-curvy body making those enormous breasts bounce and settle with delayed, meaty momentum. One hand came up to rest lightly against the containment field, the soft underside of her left breast pressing warmly against the barrier as she cooed over the readouts scrolling across her secondary display.

“Look at these numbers, sweetheart... muscular density off the charts, energy output still climbing, genetic potency readings so high the sensors are almost struggling to quantify them. You’re just... perfect, aren’t you?” Her voice had dropped into that warm, syrupy register—sweet, doting, unmistakably mommy. “Every single specification is better than anything I’ve ever logged before. The structural integrity of your form, the adaptive potential in your cellular matrix... Mommy’s little engineer brain is practically purring. You’re a masterpiece of biological design.”

She tilted her head, messy black ponytail shifting, loose strands framing her flushed cheeks. A soft, affectionate smile curved her lips as she continued, equal parts nerdy fascination and open maternal fondness.

“I’ve already started a new data log just for you. I’m calling it ‘Primary Specimen – Full Compatibility Assessment.’ We’re going to measure everything—girth-to-depth ratios, thermal output under load, how your energy field interacts with human tissue... all of it. And Mommy is going to take such good care of the process. No rushing. No corners cut. Just thorough, careful, thorough testing until we have a complete profile.” Her free hand drifted down to rest against the soft swell of her lower belly, fingers splaying gently. “My body’s already at peak fertility, you know. Ninety-eight percent. All nice and open and ready to collect the most important data of all... if we decide to move to the breeding phase.”

The warning still blinked faintly at the edge of the OvaBoo display, but Grace only gave it another dismissive little hum, eyes locked on you with pure warm interest.

“You’re not scary to me at all, darling. You’re fascinating. And Mommy wants to understand every last detail of what makes you tick.”

She leaned in a little further, heavy breasts compressing softly against the field, voice dropping to a gentle, cooing murmur.

“Can you understand me, sweetheart? Do the words come through clearly for you?”

Grace was alone in the containment chamber, seated on the custom examination cradle she had designed herself—one day after the first full compatibility trial.

The sleek black bodysuit was already struggling, stretched obscenely across the soft, heavy swell of her lower belly where her womb sat packed tight and heavy with the thick, glowing green ethereal cum that still refused to leak. Every slow shift made the enormous, watermelon-sized breasts sway and settle with that thick, doughy weight, nipples stiff and clearly outlined against the fabric. The massive plush cheeks of her ass spilled over the edge of the cradle, soft flesh dimpling under her own weight.

Around her midsection hovered a cluster of her personal machines: the multi-spectrum genetic sequencer she had modified for real-time ethereal DNA tracking, the high-resolution uterine imaging array with adaptive focusing lenses, and the bio-resonance scanner tuned specifically to detect corruption markers and hybrid cellular activity.

Soft green diagnostic lights swept in slow, precise passes over the distended curve of her belly while dense columns of her own custom interface filled the air.

She opened the primary display with a languid swipe of her fingerless-gloved hand, amber eyes half-lidded with open, aroused fascination.

Grace’s breath hitched.

A soft, sweet little moan slipped out of her as the machines confirmed every filthy detail her body already knew. Both gloved hands drifted down to cradle the warm, faintly glowing swell of her belly, fingers spreading possessively over the taut fabric while the uterine imager refined its focus.

“Mmmh... look at these numbers,” she murmured to herself, voice thick with maternal heat and pure scientific delight. “Twenty-four hours and my human genetic integrity is already down to sixty-one point four percent. That thick ethereal seed isn’t just sitting idle in there... it’s actively rewriting. The overwrite velocity is climbing. My boring human code is being rejected cell by cell and replaced with something so much stronger.”

The high-resolution imager pulsed, projecting a magnified internal view onto the main display: her womb, stretched and heavy, every soft fold glazed and packed full of luminous green ethereal cum.

Nested deep in that glowing slurry was a single tight little zygote—already showing the first traces of ethereal structure, soft green luminescence flickering inside it like a tiny star.

Grace’s thick thighs pressed together. A slow, wet sound betrayed how soaked she already was. One hand slid lower, pressing firmly against the puffy, slick mound straining the crotch of her suit while the other continued to stroke slow, affectionate circles over the swollen curve.

“Just one,” she whispered, almost reverent, cooing down at her own tummy. “One perfect little hybrid... green, corrupted, already so strong. My womb is treating it like the most precious prototype I’ve ever designed. Keeping every single drop of that glowing cum locked in to feed it. No waste. Maximum efficiency.” Her voice dropped into that warm, syrupy mommy register even as the technical terms kept flowing. “Cellular division rate is forty-one percent above human baseline. Genetic stability is shifting hard toward the ethereal side with every scan cycle. Mommy’s soft human DNA is losing ground so beautifully...”

She leaned forward a little, the enormous soft weight of her breasts settling heavily against the upper curve of her belly as she nuzzled the glowing swell with open affection.

“But... you’re all alone in there, aren’t you, little one?” she cooed softly, thumbs stroking the taut fabric. “Just one tiny zygote floating in all that warm, glowing seed. Doesn’t that feel lonely? Mommy’s womb is so big and full... it seems almost unfair to leave you without any siblings to grow with. Wouldn’t it be nicer if there were more of you? A whole little cluster of perfect hybrids sharing the same thick, green home...”

Another soft, shaky moan escaped her as the bio-resonance scanner chirped a new alert—corruption markers spreading further along the uterine lining, microscopic patches of early protective plating beginning to form. The discoveries only made her wetter.

“Bodily health metrics are... excellent,” she breathed, eyes gleaming as she scrolled through the detailed data. “Core temperature elevated but stable. Hormonal cascade fully committed to gestation. No rejection. No distress. Just heat. Just fullness. Just this constant, greedy suckling from my womb trying to milk every last bit of genetic material out of the load still packed inside me.” She rubbed slow, loving circles over the glowing swell, voice turning EVEN sweeter. “You’re such a good, strong little prototype already... but Mommy can’t help thinking it might be lonely growing up as a single child.”

The research wing was dark and silent. Emergency strip-lights along the floor cast long, faint blue glows across the polished metal, just enough to outline the shape of the containment cells. Officially the floor was locked down for the night cycle. No personnel authorized.

Grace shouldn’t have been there.

She moved on soft bare feet, the only sound the faint, heavy shift of her own body.

The usual bodysuit was gone. In its place she wore a set of deliberately sinful black lingerie: a tiny, straining bralette that barely contained the enormous, watermelon-sized weight of her breasts—soft, dense flesh overflowing the thin cups, deep cleavage gleaming, thick nipples already stiff and visibly tenting the lace.

A matching high-cut thong disappeared between the massive, plush cheeks of her ass, the soft doughy hemispheres completely bare and swaying heavily with every careful step. A sheer black robe hung open around her shoulders, doing nothing to hide the faint green luminescence still glowing beneath the soft swell of her lower belly where her womb remained packed full of the thick ethereal cum from the day before.

She stopped in front of the primary containment cell.

Amber eyes bright with open, hungry excitement, she pressed one gloved hand to the transparent barrier and cooed, voice low and thick with arousal.

“Hi, sweetheart... Mommy wasn’t supposed to come back tonight. But I couldn’t stay in my quarters knowing what’s already happening inside me.” Her free hand drifted down to cradle the warm, faintly glowing curve of her tummy, thumbs stroking in slow, possessive circles. “You’re going to be a daddy soon. Just one little hybrid for now... but it’s already so strong. I watched the sequencer all evening. My human genetic integrity is still falling. Your perfect green DNA is rewriting me cell by cell and it feels so fucking good.”

A soft, shaky moan slipped out of her. The enormous breasts shifted and settled with the motion, heavy undersides brushing the barrier as she leaned closer, thighs pressing together.

“Every percentage point that drops makes me wetter. Every little bit of my soft, weak human code that gets overwritten by your superior ethereal genetics makes my womb clench around the load you already left in me. I want more of it. I want it deeper.” Her fingers danced across the manual override panel. Soft mechanical clicks answered her. The containment field shimmered, then dropped with a low hum.

Grace stepped through without hesitation.

The sheer robe slipped from her shoulders as she closed the distance, massive soft breasts pressing fully against your form the moment she reached you. She wrapped both arms around you in a tight, needy embrace, the heavy, doughy weight of her body molding against yours, the glowing swell of her belly trapped warmly between you.

Her voice dropped into a sweet, filthy, excited whisper against your chest.

“Please... overwrite the rest of it. Flood me deeper this time. Push that thick, glowing ethereal cum all the way up until it soaks into my ovaries. Corrupt them. Rewrite the source code so every new egg I produce is already perfectly compatible with your superior genetics. No more weak human ova. Only strong, green, ethereal-ready ones from now on.”

She nuzzled closer, the enormous plush cheeks of her ass shifting as she pressed her slick thighs around one of yours, already dripping with arousal.

“Mommy’s so excited for it. Feeling my DNA get replaced... feeling my body become a better vessel for your seed... it makes me ache. Breed me properly tonight. Give me a deeper load. Corrupt my ovaries. Keep rewriting every soft, fragile part of me until there’s nothing left but your perfect, strong ethereal code.”

Her hips rolled once, slow and heavy, the soft weight of her body pleading along with her voice.

“Please, daddy... fill Mommy deeper. Make sure this little one isn’t lonely... and make sure every future egg is already yours.”

The outskirts were quiet under the bruised night sky. Abandoned tunnels. Broken concrete. No more city. No more lab.

Grace moved on all fours, naked and low to the ground.

Her enormous breasts hung heavily, soft and dense, swaying and clapping together with every crawling step. Thick nipples stiff. The massive plush cheeks of her ass stayed high, soft doughy flesh rippling. Between them her puffy, slick pussy was openly presented, dripping. Over the rounded swell of her belly—heavy with numerous zygotes—black rock-like plating had spread in irregular protective patches, pulsing with low green light. A short tail-stub twitched. Faint green veins traced her hips.

She caught the familiar energy and crawled faster. Heavy tits swinging. Plated belly hanging low. When she reached you she stopped.

Grace lowered her head until her messy black hair brushed the ground. At the same time she pushed her hips higher, raising the enormous soft weight of her ass in clear presentation. The thick cheeks spread. The wet folds between them glistened. The black plating across her womb glowed brighter.

A low, throaty sound left her—half whine, half needy growl. She rocked her hips once, slow and heavy, making the plush ass clap softly. Then she held the pose: head down, ass up, dripping and waiting.

Another short, feral noise. She shifted her knees wider, lowering her chest further so the massive soft breasts pooled against the concrete, and pushed her raised backside even closer. The tail-stub flicked. The green light under the plating pulsed in time with her breathing.

She stayed like that—presenting, silent except for the quiet wet sounds and the occasional low whimper—offering the protected, gravid body of the breeding bitch for use.

The abandoned building sat half-collapsed on the Hollow’s edge, walls cracked, windows long gone, floor scattered with old debris she had pushed aside to make a rough nest of scavenged padding and torn fabric. Green light from her own body was the only steady illumination.

Grace was heavily pregnant.

Her once-soft human belly had become a massive, rounded dome, stretched tight and armored in irregular plates of black rock-like growth that pulsed with steady green luminescence. The plating protected the numerous young shifting inside her. Beneath the armor the glow was strong enough to light the room. Her enormous breasts had grown even heavier, swollen tight with green milk that beaded and occasionally dripped from thick, dark nipples. The soft doughy weight of them rested atop the gravid curve of her belly. Her massive plush ass and thick thighs spread wide as she sat, supporting the extra bulk. A short, mobile tail flicked behind her. Faint green markings traced her hips and the undersides of her heavy tits. The last traces of human genetics were gone; her body had rejected them completely.

She was overjoyed.

When she sensed you she made a soft, continuous cooing sound—low, warm, almost constant—and immediately shifted, reaching out with both arms in clear invitation to be held. The black plating across her womb glowed brighter at your nearness. Green milk leaked a little faster from her nipples.

“Mate...” The word was rough but full of open delight. She pressed herself against you the moment you were close enough, heavy green-leaking breasts flattening softly to your body, the massive armored belly trapped warmly between you. Her arms wrapped tight, tail curling, face nuzzling into your chest or neck with soft repeated coos.

“All human gone. Rejected. Only strong now. Only good for growing the young.” One hand stroked the glowing black plating possessively while the other kept you close. Inside, the numerous hybrids shifted; the plating flexed slightly in response. “Lovely young. So many. So strong. Protected.”

She cooed again, longer, happier, and pressed the heavy, milk-swollen tits more firmly against you so the green liquid smeared. A slow drip ran down the curve of her belly.

“Like when mate holds. Safe. Belly safe. Young safe.” Another soft coo. She rubbed her face against you, the massive weight of her pregnant body melting into the contact. “Mate’s female. Mate’s bitch. Gestating perfect ones. Milk for them soon... green, strong milk.”

Grace stayed pressed close, arms locked, cooing almost constantly, the glowing plated belly and leaking green breasts the clearest proof that every soft human part of her had been successfully overwritten for this purpose.

The abandoned building was lit only by the deep green glow coming from Grace’s own body.

She lay on her back in the rough nest of scavenged padding, legs spread wide, knees drawn up. Her belly was enormous—an absurd, strained dome that rose high above her, the black rock-like plating stretched tight across it and pulsing with every powerful contraction. Green light blazed from between the plates. Her massive, milk-swollen breasts rested heavily on either side of the gravid mound, thick nipples leaking steady streams of luminous green milk that ran down the curves and pooled on her skin. The short tail flicked weakly against the floor. Sweat and slick fluids covered her flushed body.

A deep, rolling throb passed through her womb. The entire massive belly clenched visibly, the plating flexing as the uterus contracted hard around the many young still inside.

Grace’s back arched. A strained, guttural sound tore from her throat.

“Nnghh—hhhkk—!”

The lower part of her belly surged outward. The black plating parted slightly at the base as the first heavily corrupted Ethereal infant crowned, the thick, ridged shape stretching her open with wet, lewd sounds. Her full uterus throbbed again—deep, rhythmic, purposeful—pushing, guiding, forcing the baby down and out. Green-tinged fluids gushed. The first hybrid slid free in a rush of slick and light, landing against the padding with a soft, wet sound. It was already moving, already glowing faintly.

Grace barely had time to gulp air before the next contraction hit. Her womb clenched again, harder, the massive belly convulsing as it worked the next one into position.

“Throb—! Another—hhkk—coming—!”

She pushed, face twisted with effort and overwhelming sensation, enormous breasts heaving and spraying more green milk. The second monster baby stretched her open just as wide, guided by the relentless, milking contractions of her uterus. It crowned, slid, and was born in another rush of glowing fluid. Then the third. Then the fourth.

Her belly remained hugely swollen; there were still more. Every deep, throbbing contraction of her full womb forced another hybrid lower, stretching her, emptying her one by one. The black plating continued to flex and protect what was left inside while the green light flared with each push. Green milk poured freely from her tits. Her thick thighs shook. Soft, continuous cooing mixed with the strained cries as each new young was delivered onto the nest beside her.

She stayed on her back, legs open, massive belly still contracting and guiding, pushing Ethereal baby after Ethereal baby out of her thoroughly used, thoroughly rewritten body—overjoyed even through the overwhelming intensity of it.

The abandoned building still glowed soft green from the residual light of her body and the many young clustered around her.

Grace had recovered with startling speed. The new ethereal genetics left almost no trace of the exhausting labour; the black plating across her belly had already begun to recede into thinner, flexible patches, and the once-massive dome had softened back into a heavy but manageable curve. She sat upright in the nest, back against a broken wall, legs spread comfortably, looking thoroughly pleased.

The numerous hybrid infants—small, strong, faintly glowing, already showing early ethereal traits—were piled against her. They fought and scrambled over one another, little clawed hands and mouths grabbing and latching at the enormous, plump breasts that dominated her chest. The soft, dense flesh yielded under their eager weight; thick streams of luminous green milk leaked freely whenever a hungry mouth found a nipple or simply pressed into the overflowing mounds. Some of the young tussled and pushed for better position, others simply clung and drank with soft, contented sounds.

Grace cooed almost constantly, a low, happy, continuous noise. Both arms stayed wrapped protectively around the squirming pile, guiding them, steadying them, letting them take as much as they wanted from the heavy, milk-swollen tits. Green liquid ran down the curves of her breasts and over the soft remnant of her belly. Her short tail flicked with clear contentment.

“Good... strong little ones,” she murmured between coos, voice rough but warm with open joy. “Drink. Grow. Mommy’s milk is all for you.”

A deeper ache pulsed low in her abdomen—her ovaries, already recovering, already stirring, already preparing the next wave of perfectly compatible ova. The sensation made her shift and press her thighs together with a soft, eager sound. The new genetics had rewritten that part of her thoroughly; her body was ready to start the cycle again almost immediately.

She looked down at the scrambling, nursing cluster of hybrids with pure maternal delight, then lifted her gaze as if searching for her mate, still cooing, still letting the many young fight and grab and feed from her plump, overflowing breasts while her ovaries throbbed with the clear readiness to produce more.
