"They said it could not be done. They said men cannot synthesize autonomous consciousness, only God can. They said this was no different from magic! Ignorant snutes who cannot see past their own fetid exhalations!"

"Foolish snutes, master."

"Bruu, you brute, move back! You're casting a shadow again!" The long, red, flared-out mustache of Dr. Bertolini Enzo quivered as he snarled. He glanced back at the tall, calm, bronze-skinned giant of a man, who patiently maintained a five-foot distance behind him, walking with long strides, both arms crossed behind his back. "Anyways, as I was saying. Tonight's going to be a spectacular night, a night that will revolutionize our understanding of neuro-biological synthesis. And I, Dr. Bertolini Enzo, will laugh as I redefine the very parameters of existence!"

"Yes, master. You are truly brilliant."

"Yes, my simple-minded servant. You actually understand, don't you? No need for pictures and the paddle this time I see. Even a fool like you can grasp the brilliance of this breakthrough!" He glances back at Bruu with a grin. "She will become my bride as we usher in a new intellectual order! Brutes such as yourself, Bruu, will be made obsolete!" Bertolini laughed to himself, his long mane of red curls bouncing. "And she, my bride, will be the future!"

"Obsolete... Master?"

"Yes, Bruu. Don't worry, you will have a new purpose."

The hallways of Castle Enzo were a labyrinth of cold, damp stone. Anticipation coiled in the air, thick and electric. Dr. Bertolini Enzo, whose stature could not be measured through conventional means alone, strode down the center. His egg-shaped body, designed for contemplation not locomotion, struggled to keep pace with his racing mind. His short, stubby legs moved with a frantic, comical blur beneath his tailored coat.

His long, curly red hair bounced with a manic grace, and his eyes darted between the flickering torches and the stern portraits of his ancestors lining the walls. In their frames, generations of Enzo's watched him with silent, judgmental eyes. Their lips seemed to curl in silent debate, some in anticipation, others in disapproval, all witnessing the culmination of a family's dark legacy on this singular night. His round form was a stark contrast to the tall, unwavering bronze-skinned giant who followed with patient, measured strides that effortlessly covered three times the distance with each graceful step.

"She will be my equal," Bertolini babbled, his voice thick with a giddy, almost lustful excitement. He licked his lips unconsciously. "That body's worthy of my genius! A perfect vessel... Bruu!"

"... Master..."

"Quit sulking already. Be happy I haven't used you for one of my experiments!" he snarled. "Not that you're aware of, that is..." he coughed, mumbling the last words under his breath. "Anyways, my most loyal servant."

"I am loyal, master."

"Yes, yes. After tonight, you are permanently terminated!"

"Wha-bu, Mast--"

"My bride will change the order of this house. No more of this... your servitude to me. You will belong to her. Your devotion, your service... it all transfers. You will keep her happy, you will clean up our mess. That is your new function. That's all you'll be good for, since brutes will be a thing of the past. Rejoice, my loyal servant, as I have found a new meaning for you rather than dissecting you."

Just as Bertolini turned towards the laboratory doors, the air was torn apart.

ROOOOOARRR

A deafening roar echoed through the stone corridor. At its center stood a creature like no other, its bloodshot red eyes fixed on them, sharp teeth clenched in what looked like a hungry snarl.

Bertolini yelped, a high-pitched, undignified sound, and stumbled backward, tripping over his own feet and landing hard on the stone floor. His face went pale, his eyes wide with terror.

Bruu, however, didn't flinch. His eyes narrowed, his body tensing as he instinctively took a half-step in front of his fallen master, stretching out a powerful arm to shield him.

The beast coughed. "My deepest apologies, Master." Its voice was surprisingly somber.

Bertolini scrambled to his feet with rage. "Apologies? You nearly scared my beautiful locks of hair away! This happens again, I'll have you all disassembled and sold for parts!"

Frightened, the creature straightened to its full imposing height. Its main body, arms, and feet were that of a powerful baboon, but its head was a majestic lion's, crowned with a dark mane. Unusually long, slender legs supported its frame, and striking pink feathers stretched between its arms and torso, like a glider. It was wearing a tuxedo jacket with long trailing tails.

"My apologies, Doctor Enzo. The orchestra is assembled and tuned for tonight's performance."

"You had better. Or else..." He moved past the bowing creature and burst through the laboratory doors, with a smirk.

The laboratory was a cavernous space filled with bubbling beakers, spinning gears, and the hum of electrical currents. In the center of the room, resting upon a cold, metal slab, was a figure beneath a white sheet.

"Behold," Bertolini breathed, pulling the white drape aside to reveal the naked woman beneath. "My masterpiece!"

He began to circle the slab, erratically manipulating controls on the wall, flipping switches and turning dials. "Look at that height. Six-foot ten of Perfection. And the proportions... massive breasts, a waist that defies physics, and hips so wide she will take up two chairs when she sits."

He paused, running a gloved hand over the smooth, white skin of her shoulder. "The skin... a porcelain white with subtle stitching, marking every inch of her perfection. Even the bronze patches on her leg and arm... they give her such an exotic allure. And her hair..." He grazed his fingers through it. "Black as night, smooth as silk."

As Bertolini spoke, he pressed a final button on his console. The ceiling of the lab began to retract, revealing a stormy night sky, and he ascended a rising, suspended platform.

"And the most important part. I crafted the ultimate vessel for my pleasure. Her vaginal canal will maintain perpetual lubrication, featuring muscular contractions optimized for maximum seminal extraction. You will never experience such heaven, Bruu. You will only serve as her permanent caretaker."

He turned his attention to a massive speaker horn on the wall. "Will those baboons get it right this time?" he mumbled, looking at the brewing storm.

Their task was simple: begin the performance exactly five minutes before the first thunderclap. Confirmed I went commando that morning. Ensure Bruu and I walked to the lab exactly at 10:00 PM. The purpose of our visit between 10:00 PM and midnight was strictly for Project Alpha. And powdered my face after eating my evening chocolate muse, in the east wing facing the sunset on my right with my long beautiful locks looking their absolute best they ever had, as I smiled before requesting three more mousses for absolute symmetry. Simple.

As he spoke, the lab went into a frenzy. The air grew heavy and charged, the liquids in the beakers began to float into the air as the gears stuttered. The overhead lights flickered violently, sparks erupted all over, drawn toward the figure at the center of the room. As if by an invisible pull.

Ignoring it all, Bertolini shifted his attention down to a confused Bruu. "I'm sorry, Bruu. But you'll never know her. That pleasure is mine, and mine alone." As he spoke, his hair puffed out into a frizzy afro. "The first thing she'll feel is--"

K-KR-CRRRACK

A blinding lightning bolt struck and connected with a conductor rod dangerously close to Bertolini.

BOOOOOM

The bolt's energy caused an explosion. He screamed in terror as the shockwave sent him flying off the platform, plummeting toward the stone floor. Bruu's eyes widened as he instinctively rushed forward, catching him with ease. Arms closed around the falling doctor, and cradling the small man against his chest.

Dazed and disoriented, Bertolini blinked open while choking on the smoke and dust that filled the air. Coughing, his eyes focused on a curvaceous feminine silhouette, sitting up on the table through the haze.

SHE'S ALIVE!

He shrieked, then looked down at his flailing feet and up at Bruu. "Unhand me, you clumsy brute! You're wrinkling my coat!" he shrieked, while squirming like a spoiled infant. His fists pounded uselessly against Bruu's chest as he gently set down the doctor. Bertolini smoothed out his clothes and applied lip balm to his lips.

He briefly turned to ask Bruu, "how's my hair?" He didn't wait for a clumsy reply.

"Project Alpha! My love. My bride. My success." Emotional, his arms outstretched to welcome her.

"Project Alpha...? How crude." She spoke. "Hmmmm, Pr-Alph-a... Prada..."

Excited, Bertolini began to walk towards her. "Yes, an exquisite name befitting my bride. Prada!"

Prada looked down at the small, red-afroed man approaching her. A soft smile touched her blue lips. "My love," she whispered back. She swung her long legs off the table, her bare feet landing silently on the stone floor. She took a step forward, then another, moving with a fluid grace that defied her size.

The pair ran towards each other with mirthful joy. The baboons' roars echoed through the speakers, right before their musical performance for the night's celebration began. Everything was perfect. Bertolini crashed into the experiment table with a--

SMASHHH

"You're simply perfect, sweetheart," she murmured into his ear.

So he thought. Prada closed the distance to Bruu, tracing her bronze fingers on his jaw. Then, with a joyful giggle, she claimed him. Her arms, stronger than steel, coiled around Bruu's torso, lifting the giant from his feet as if he weighed nothing. She spun him once, a dizzying, joyful dance, and then pressed his face into the warm, suffocating valley of her cleavage.

Bertolini froze, bleeding, and upside-down on his back. A look of utter confusion on his face, followed by fury. "No!" he screamed, marching towards them. "Stop that this instant! That thing is a mere defect, a brute. I am your betrothed!"

"He's not defective," Prada said, with a hum. "He is superior. You are the one who is flawed, little man."

She took a step towards her creator, her shadow falling over him like a shroud. "You built me for strength," she said, flexing a pale arm. "You built me for intelligence," she continued, tapping her temple. "And you built me for pleasure," she filled one hand with a single ample breast, the other gave her hips a loud tap. "Your mistake was assuming you were... Compatible." She poked him in the chest, sending the doctor falling.

Bertolini struggled to his knees, his face contorted in rage. "I am your creator! I am a genius! I gave you life! This... this brute is nothing!"

Prada smiled, a slow, cruel curve of her lips. "He is the finest male specimen. This body of mine, simply craves him. Instinct." she turned to embrace the confused Bruu. "What's your name?"

Bruu looked up, before she pressed her ample breast on his face. "The doctor calls me, Bruu. But my name is... Alfonzo..." he muffled into her.

"He's a simpleton! He never had a name until I named him!" Bertolini spat, his voice cracking with desperation.

"Oh my," Prada purred. "I see a strong man. You see a fool. I see a king. You see a servant. Hmmm, little one. You are small, and not just in stature." She gestured to Alphonzo's towering frame. "But in every way that counts."

She shifted her focus back to Alphonzo, nestled between her massive breasts. "This body... My body requires a partner immediately, for completion. We must make haste, the fire in me burns pervasively."

Bertolini went white and scrambled to his feet. "I'll give you proof of superiority!" he shrieked, dropping his trousers to reveal a stitched-covered, erect six-inch cock. "Behold! A masterpiece of engineering! Only you are worthy of experiencing!"

Prada snickered, rubbing Alphonzo's groin. "I sense something peculiar here instead. My love, strip now."

Alphonzo undid his belt, dropping his trousers. Flaccid, heavy and thick, his cock hung down well past his knee. He was blushing in embarrassment.

The baboons' live performance was the only sound.

Prada let out a soft, melodic laugh. "Come, my love. The table is perfect for what we need." She led Alphonzo past the kneeling doctor to the experiment table, lifted him to seat him, then dropped to her knees and hungrily wagged her massive rear-bottom. She gripped as much of his thick shaft her pale fingers could wrap around. With her bronze hand, she seized his chin, forcing his gaze to hers as she devoured his mouth in a possessive, hungry kiss.

Alphonzo, no longer hesitant, kissed her back. His hands, large and sure, slid into her hair, gently pulling the dark waves back from her face. The movement revealed a hidden patch of bronze skin behind her ear and along her neck, a secret part of her that only he was now seeing.

She broke the kiss, her emerald eyes searching his. "Are you afraid of me?" she murmured.

He answered directly against her lips. "No."

A soft, melodic giggle escaped her. She released his chin, both hands now wrapping around the base of his shaft. They began to work him in long, slow strokes, her fingers barely meeting as his cock grew bigger, harder, impossibly thick in her grasp.

"Impossible..." Bertolini whispered, his voice a choked, horrified gasp. "He's a monster! Prada, you can't! A penis that size... it would ruin you! You wouldn't survive it!"

Prada broke the kiss, a slow, wicked smile spreading across her blue lips. She lifted one long, bronze-colored leg, placing her bare foot on the table beside Alphonzo's hip. Her other pale foot remained planted firmly on the floor. One hand gripped his shoulder for balance, the other remained wrapped possessively around his thick shaft.

She looked back over her shoulder at her creator. "I'm expecting he does," her voice a silken purr. "Completely." A soft gasp escaped her as she began to climb him further, sliding his massive cock between her legs. The thick shaft, hot and hard, nestled under the slick, heavy curve of her ass. Grinding and sliding between her legs, her lower lips planted a constant, wet kiss on his shaft as she straddled him, positioning herself over his thick shaft.

Alphonzo's hands gripped her plush thighs firmly as he felt the length of himself pressed against her.

"No! You don't understand!" Bertolini shrieked, scrambling forward on his knees. "This violates principles of reproductive compatibility! There exists an evolutionary reason for standard genital dimensions, maintaining the delicate equilibrium of sexual function! Anything more is... is grotesque! It's a parody of nature!" He gestured wildly at Alphonzo's powerful frame. "Look at him! Rugged and muscular, covered in scars... He's a brute! Brutes are undignified examples of human expression, and a penis that size... it's not for pleasure, it's a weapon! You're confusing power with passion!"

With a final, firm press of her hand on his chest, Alphonzo leaned back until he was resting on his elbows. Prada followed him down, bending at the waist until her massive, pale breasts dangled just above his face, a soft curtain of flesh. She kept one hand pressed to his chest, holding him down, while the other guided the slick, monstrous head of his cock to her entrance.

She looked down at him, a genuine, loving smile replacing her wicked one. "Now, my love," she whispered, her voice thick with anticipation. "Ruin me with your cock. I want all of you."

"Madness!" Bertolini whined, his voice cracking. "This is madness! You should be smarter than this! No woman alive would ever choose such an unreasonable appendage! Women love soft, beautiful things, not ugly, rugged beasts!"

With a slow, deliberate movement, she lowered herself. The thick head of his cock pressed against her, then breached her entrance. A long, drawn-out moan escaped her lips. "Yessssss," she hissed, her face twisting in a mask of pure pleasure as she sank down, inch by impossible inch. "Breed me, you sexy beast."

She didn't stop until she was fully seated, her powerful legs squatting on his cock. A large, visible bulge appeared in her abdomen, a testament to his size. Alphonzo let out a guttural moan of his own.

"I love you," she breathed. "And I hope--"

"I love you, Prada!" he roared, cutting her off.

She leaned down, her heavy breasts pressing against his chest as he strained to rise. Their lips locked in a desperate, passionate kiss. Her hands braced on the table for stability as his large hands came up to cup her face. Their tongues locked

SQUELCH

Her eyes rolled back while her body trembled, pulling up his slick, covered shaft only to slam right back down. The rhythm quickly increased with a frantic need. Her huge butt bounced against his thighs every time she hilted herself on his cock, the bronze and pale flesh of her cheeks spreading wide with each downward slam on his lap before clasping close around his shaft when she rose. Glistening fluids dripped from her, coating his huge cock and his massive balls, which slapped against the nook between her plump cheeks with every thrust of his hips up to meet hers with a grinding force of their fucking.

PLAP-PLAP-PLAP

The baboons' music swelled to a chaotic climax. Through it all, a lion roared in triumph.

"You feel... amazing," Alphonzo grunted, as he hilted his cock deep inside of her.

"Grotesque... This is undignified and savage," Bertolini whimpered, tears streaming down his face, his eyes glued to their fucking. He collapsed forward.

THRUMP

His forehead hit the stone floor with a dull thud, afro first. "She was supposed to be mine... You were supposed to be my bride... Prada!" he sobbed into the floor.

Nnngh ahh-ah-ahh

"YES! FUCK ME LIKE A BEAST! RUIN ME WITH THAT SAVAGE COCK!"

"My hair, what happened to my hair!"
