To the mansion's basement...

The Womb Crest – Eternal Enslavement

The basement air crackled with arcane corrupt energy as Stefano stood between his two trembling conquests—Vanessa sprawled across the leather chaise, the slutty milf's belly already swollen with the incubus' tainted seed, and Beatrice kneeling on the cold concrete, her virgin cunt still dripping with the demon's corruption.

Brand them

The Osiris ring pulsed violently on the middle-aged archeologist's clawed finger, its violet light casting eerie shadows across their sweat-slicked bodies.

Stefano's golden eyes burned with dark purpose as he extended his claws, the razor-sharp tips glowing with hellish energy.

"You've taken my seed," he rumbled, his voice resonating with supernatural power. "Now you'll take my mark."

The Branding Ritual – Claiming Flesh and Soul

Vanessa whimpered as Stefano pressed his burning claw against her lower abdomen, just above the slutty, blonde mother's dripping cunt. The scent of scorched corrupt souls, decadent and honeyed, filled the air as the demonic sigil seared into her pale skin—an intricate, pulsing crest of intertwining serpents and thorns, glowing the same violet as Stefano's flames.

"Ah! F-fuck! It burns—!" she screamed, her back arching off the chaise.

Stefano gripped her throat, silencing her cries. "The pain is nothing compared to the pleasure you'll feel serving me," he growled. The mark flared brighter, tendrils of dark energy snaking up her torso, wrapping around her breasts before sinking into her womb.

"F-FUCKING SHIT!!"

Vanessa's eyes rolled back as the corruption took root—her nipples darkened, her breasts swelled with unnatural fullness, and a fresh flood of arousal gushed from her cunt. The crest pulsed in time with Stefano's heartbeat, binding the mansion's matron to him in body and soul.

Beatrice watched in horror and fascination, her fingers unconsciously drifting to her own lower belly.

"Y-You can't—"

Stefano was on her in an instant, pinning the young slender woman to the floor with one scaled hand between her breasts. "You begged for this, little dove," he reminded her, his claw tracing circles around her navel. "Now you'll wear Osiris mark where everyone can see."

The branding was slower this time—Stefano relished Beatrice's choked sobs as the crest burned into her very soul, the same wicked design as her mother's, but smaller, more delicate, marking the young blonde heiress as the incubus' newest possession. As the magic took hold, her body convulsed—her hips bucked, the slender woman's freshly deflowered pussy clenched around nothing, and her small breasts tingled as they began to swell with unnatural sensitivity.

"N-No... I don't... I don't want this—" Beatrice gasped, even as her traitorous body arched toward him.

Stefano chuckled darkly, his claw dragging down to her weeping slit. "Your body says otherwise."

The Breeding – Claiming Their Wombs

With both women branded, Stefano wasted no time. He hauled Beatrice up by her hair, forcing her onto all fours beside her mother on the chaise.

"Observe, Vanessa," he commanded, his voice thick with power. "Watch as I ruin your daughter properly."

Vanessa moaned, the ravenous milf's fingers drifting to her own marked belly, already imagining the life growing inside her.

Stefano positioned himself behind Beatrice, his cock—thick and glistening with her arousal—pressing against her tight entrance.

"This will bring you moderate discomfort...," he purred, "but you'll love it by the end."

The incubus slammed forward in one brutal thrust, splitting her wide, the young heiress' tight cunt stretching obscenely around his girth.

Beatrice screamed, her nails digging into the leather, her body fighting and failing to reject him.

"S-Stop! Please! It's too big—!"

Stefano ignored her, his hips pounding into her with merciless ****, the demon's claws digging into her hips hard enough to almost draw blood.

"You're mine now," he growled, his voice laced with dark magic. "Your body, your womb, your soul."

With each thrust, the crest on Beatrice's belly pulsed brighter, the magic sinking deeper, rewriting her very essence to crave his seed.

"All mine."

Her screams turned to moans, Vanessa's daughter,,, The young woman's lingering resistance crumbling as pleasure overwhelmed her. Her own slutty mother watched, enraptured by the corrupt breeding.

"F-Fuck! Yes! More!" Beatrice begged, her back arching, the pale blonde's tight pussy clenching desperately around him, trying to milk her virile demonic lover dry.

Stefano roared, his release boiling over, his cum flooding her womb in thick, pulsing ropes.

Beatrice's belly swelled slightly, her virginity stolen again, her fate sealed.

The Final Enslavement – Breaking Their Will

With both women filled and marked, Stefano stepped back, admiring his handiwork.

Vanessa was panting, her fingers kneading her swollen belly, her eyes glazed with submission. Beatrice collapsed onto the chaise, her body trembling, her mind fogged with pleasure and dark magic.

Stefano smirked, his tail flicking lazily.

"Now," he purred, "who wants to be fucked first?"

Two voices answered as one:

"M-me!"

Stefano's laugh was dark and rich as he positioned himself between them, his cock aching for more.

The basement echoed with screams of pleasure as Stefano claimed what was his, the Osiris ring pulsing in time with their joined rhythms, its violet light painting their writhing forms in shades of ecstasy and surrender.
