A new succubus is born

Michael’s response was a deep groan as Sandra had finally moved close enough to capture the throbbing head of his enormous cock in her drooling maw. Wrapping her expert tongue around his pulsing cockhead, she moaned with glee as she tasted his precum before letting his cock slither its way down her throat. Her saliva dribbled down his dick to his balls. Her growing fangs scraped along the sides, and she groaned as she tasted his foul blood.

"That's it, my little whore …" The demon rumbled as he played with her mane of blonde hairs.

Sandra looked over her shoulder at Keith, running her black tongue over Michael’s cock. Her boyfriend got the message and moved behind her, grabbing her ass firmly as she released one long, slightly gagged moan around Michael’s dick, girlcum dripping out of her pink honeypot.

“Fuck me baby” she urged him.

Keith didn’t need further instructions and quickly plunged his dick in his girlfriend’s steaming cunt. The feeling of her hot slit contracting tightly around his member causing him to pump out a long release of prejizz deep into her sex. Sandra squeezed his massive member with her pussy. In return Keith hammered the blonde's cunt even harder, which caused her sucking to become more difficult. Michael’s reaction was quick. Grabbing hold of the back of Sandra’s head, he pushed her mouth down onto his cock, leading her to engulf almost half of it in one swift motion. Sandra’s eyes went wide, gagging and **** a little as bursts of slobber got coughed out onto Michael’s ballsack as her boobs mashed into his thighs.

"Give up your old self. Become the perfect whore” Michael said as he dropped his disguise while he was moving back and forth, thrusting even more of his inhuman dick down her throat. “You just need to give me your soul”.

"You want to suck every cock... to drain them of their cum... like the evil little slut you will be." He tilted her chin up as she worked his cock, locking his evil gaze onto her beautiful, **** face. "Now, destroy that soul. Destroy it and you will get never-ending ecstasy.”

Sandra moaned with approval. Closing her eyes, she found inside herself the unique glow inside that still barely held onto her corrupted body. She tore it apart, sending it into the depths of Hell.
Her eyes shot open, locked on Michael’s as her lips stretched around his cock, gulping more of it. Only endless hunger and sexual depravity remained in her red, serpentine eyes. She wrapped her arms around Michael, digging her curved black claws into his taut ass.

His buttocks strained, forcing more of his massive dick into Sandra’s throat. She growled hungrily, forcing her head down onto his crotch as the entirety of his member somehow disappeared between her lips. Her forked black tongue lapped at his cum-filled balls, coaxing them to shoot off into her stomach.
Before Michael’s eyes, Sandra’s flesh turned into a beautiful shade of blue. A pair of black horns emerged from her blonde hairs while dark wings grew from her back. But Sandra didn’t care about that right now as she snarled for more cock, spit-roasted between her 2 lovers, making her deliciously swollen bubble butt jiggle around the length impaling her. Her already sexy form blossomed into voluptuousness, hips widening sexily as Keith fucked her deeper and deeper.
“Very good little slut” Michael said. “Now take your reward” and with a mighty bellow, he emptied his balls in Sandra’s hungry mouth, blasting gallons of evil black cum into the soulless seductress’s hungry maw.

At the same time she felt Keith’s still human cock swelling in her pussy before erupting in her womb. The sensation of thick, hot spunk being sprayed in her foaming honey box gave her another orgasm. The succubus’s pussy tightly grabbed his dick as it dumped more cum inside her, both her own juices and those of Keith squirting from her throbbing pussy.

Glancing over her shoulder, Sandra shot the panting human a nasty, fanged smile as she was using her skilled pussy to milk his cock, her new cock-tipped tail enlacing his waist.

“Mmmmhhh, I feel sooo good now baby. Time to share my gift with you” she said.
