Rebecca's Succubus evolution

Rebecca’s Ascension

The air in the master bedroom was thick with the scent of sex and power, a heady musk that clung to every surface, every breath. Rebecca lay at the center of it all, her body writhing, the slender vixen's pale skin glistening with sweat and other, more lewd fluids.

"Nnngh..."

The violet sigil above her womb pulsed like a second heartbeat, its glow intensifying with every passing moment, tendrils of dark energy creeping outward, spreading across her abdomen in intricate, claiming patterns.

She was evolving.

And Stefano watched, his demonic form towering over her, the incubus' fat cock throbbing with anticipation.

"Look at you," he murmured, his deep baritone layered with dark pride. "My perfect little broodmother."

Rebecca whimpered, her emerald eyes—now fully slitted—locking onto his.

"D-Dad..."

The redhead beauty's lithe fingers dug into the soiled sheets, her back arching as another wave of heat wracked her sinful body.

"O-Ohmygod!!"

His daughter's small, perky breasts had swollen, the nipples dark and stiff, leaking a thin, iridescent nectar that dripped down her torso.

"YES!!"

Her hips had widened, the budding succubus' already voluptuous ass plumping further, her fertile body reshaping itself into the ultimate vessel for Osiris Champion's tainted seed.

Amon and Lilith circled the bed like hunters looking at their catch, their crimson eyes gleaming with hunger.

"She’s ready," Amon purred, his low baritone a velvet command.

"More than ready," Lilith agreed, the Nephilim's forked tongue flicking out to taste the air. "She burns for it."

Stefano’s grin turned feral.

"Then let’s not keep her waiting."

The Claiming

The sinful father pounced.

"W-Wait!! I'm still sor-Hmmmph!"

Rebecca screamed as Stefano’s claws raked down her toned thighs, spreading her legs wider, exposing his daughter's dripping cunt to the hungry gazes of her family.

"Daddy—!"

"Shhh," Stefano growled, his cock slapping against her stomach, leaving a trail of thick, tainted precum in its wake. "This is what you were made for."

His hips slammed forward.

Rebecca’s back bowed off the bed, the pale vixen's shrill screams melting into a loud broken moan as Stefano’s monstrous girth stretched her, filled her tight pussy to the brim, the incubus' fat cock pounding against her cervix with terrifying precision.

*Plap!*

*Plap!!*

*Plap!*

But he wasn’t alone.

Amon’s hands gripped her hips, his own demonic length pressing against her ass.

"Breathe, mother," he murmured, his voice hypnotic, his power coaxing her body to yield.

Rebecca sobbed as he entered her, her body stretching obscenely around the double penetration, her cunt clenching around Stefano’s cock as Amon’s filled her ass.

Lilith crawled up her body, her claws tracing the glowing sigils on Rebecca’s abdomen.

"So pretty," she cooed before sinking her tail into Rebecca’s mouth.

Rebecca gagged, her eyes rolling back as she was filled in every hole, her body violated, her mind drowning in pleasure.

Stefano growled, his thrusts becoming brutal, his cock pulsing as he bred her deeper, harder, his seed flooding her womb with scalding intensity.

Rebecca’s belly swelled in real-time, her skin stretching taut as Stefano’s cum inflated her, her womb expanding to accommodate the torrent of his tainted offspring.

Amon followed, his own release pumping into her ass, his cum merging with Stefano’s inside her, their essence twisting together, corrupting her further.

Lilith laughed, her tail fucking Rebecca’s throat as she watched the transformation unfold.

"Almost there," she whispered.

The Awakening

Rebecca’s slender body convulsed, the petite vixen's orgasm ripping through her like a supernova.

"Nnngh!!"

The sigils on her lower abdomen flared, their corrupt pink glow intensifying until her entire body was bathed in violet light.

Corrupt

Wings burst from her back—great, leathery appendages that stretched to the ceiling, their surface shimmering with the same unholy energy as the Osiris Ring.

Dominate

A long spaded tail lashed behind her—sleek, prehensile, tipped with a devilish spade.

"O-Ohmygodd!! Yes!"

Obsidian like horns curled from her forehead—elegant, deadly.

"FUCK!!!"

Stefano roared in triumph, the incubus' fat cock pulsing as he filled her hungry womb again, his tainted seed sealing her transformation.

"My queen," he growled.

Rebecca smiled, her new fangs glinting.

"Yours," she whispered.

Forever.
