Preparing the house ... and the neighbors

On her way back home, Lydia’s corrupted mind was blooming with a multitude of ideas. She had plans for the cheerleaders but first she needed to get rid of her neighbors. She knew that the idol had gained enough power to change her building into something better.
The small building had 3 floors. On the ground floor lived Jim, the janitor, a forty something bald man and Mandy, a young blond teen who dropped high school and worked as a stripper, an easy target for the horny succubus.

Above them lived Trevor and Marsha Webb and their twin sons, Abe and Karl. Lydia shared the second floor with a Jebediah and Dorothy, a couple of retired peoples while the third floor was for Marcus, a fat bachelor and Mei, a Japanese student.

Lydia wanted to corrupt them together and she knew than the idol now had enough power to alter the Condo and its inhabitants into something more useful. She invited all of them for a meeting in her apartment; they were easily convinced thanks to her curves and her powerful pheromones.

"First I’m sorry for the unusual timing of this meeting “said Lydia, the stares o her neighbors fixed on her. “But I need to inform you there will be some major changes soon.
The crowd was feeling more and more distracted. The air was filled with Lydia’s pheromones; their drinks were laced with her tainted pussy juice. The idol was on a shelf, slowly pulsing with hellish energy. Suddenly it emitted a powerful red flash directed on them.

Lydia smiled with delight as she watched her neighbors fell into a stupor. Their blood were boiling, assaulted by the flames of primal lust, their hands were caressing and stroking themselves, then each other’s while they began undressing. Meanwhile the idol was glowing like never before, feeding on their growing lust and hidden desires.

Soon the situation degenerated into an orgy. The once shy Mei had moved under the table to grab the twins painfully erect cocks in her hands. The horny student began to switch between the two boys, slipping each of their engorged pricks down her throat as deeply as she could. She could feel each of their erratic pulses as her mouth was filled by each in turn. Despite her inexperience, she quickly found a good rhythm, matching the strong pulses coming from her throbbing wet pussy. She moaned in pleasure around each mouthful of dick, and smacked her lips lewdly as she switched her ministrations from one boy to another with skill unknown to her only an hour before.

Meanwhile the twins’ parents had fallen on the floor, panting and sweating with unbearable lust as they frantically tore each other clothes. Sarah moaned as Karl plowed into her from below. Succumbing to their lust, the delirious man kneaded his wife’s round ass as it bounced on his swollen prick. Whipping her hips up and down, her gripping pussy walls sucked mercilessly at his throbbing cock.

“Wha-what’s happening t… to us” managed to ask Karl through gritted teeth but moans and groans of pleasure were the only answers he got. His eyes bulged as their fucking was growing more and more animalistic with every passing moment, but despite that, neither of them could cum.

Lydia was standing in the middle of the room, laughing as she stared at the old couple in front of her. The old man was panting as he felt his prick grew harder than ever. Even when he was a teenager 50 years ago he had an erection like this. His wife was awkwardly removing her long skirt while groping her tits. Her worried eyes scanned over the room, taking in the sight of everyone’s furiously masturbating or fucking. But her mind could only focus on her body and her husband dick. They looked at Lydia with confusion and arousal, hating the pleasure that had stolen all reasoning and willpower from them.
Lydia was tempted to join them and show them a few tricks but she changed her mind while she spotted Mandy on the couch.

On the couch, Jack and the janitor were busy groping and fingering Mandy. The young stripper growled as she felt a surge of lust and energy coursing through her body, she was so horny that gladly accepted the ministrations of the two fairly unattractive men.
Before this, Mandy would've disgusted at these men using her body like that. She might be a bit slutty, she had limits. But now, she moaned as the duo had removed her top entirely and pulled both of her tits up to their mouth. Their pants lay around their ankles. Both of Mandy’s fists were pumping their rock-hard penis. Precum foamed out of their cock, spattering their clothes and the floor. Meanwhile the 2 men were busy licking and biting the blonde’s big tits.
Now totally naked, Lydia moved on her hands and knees, unlacing the front of Mandy’s pants and peeling them down with her panties. The busty MILF then dived between her legs, her long tongue lapping at Mandy’s pulsing pussy, brushing on her erect clit and collecting her juices. The young stripper moaned as waves of warm pleasure pulsed through her body. She tightened her grip on Henry and Marcus’s cocks, causing some pained groans from them.

"Uuuhhhhnnn... yesssss..." Feeling the lust and distress all around her, Lydia removed her human disguise, Lydia moaned as she dropped her human disguise, the black horns growing from her forehead as her body grew even more voluptuous. Her eyes shimmered red as her skin turned to a demonic crimson. She let her inhuman forked tongue slip out to wet her black lips, while squeezing her massively swollen tits with her claws.

“It’s time my friends” she shouted. “Release these pesky souls and experiment never-ending pleasure, CUM NOW !!”

Almost immediately the room was filled with howls of releases as the humans finally got their orgasms, expelling torrents of semen as well as their souls. The idol absorbed all of them in a flash of crimson energy.

Then it began.

Abe and Karl stared with reddening eyes as Mei stood up, tearing her clothes with growing claws while licking her cum covered face with a long, forked tongue.
The two black teenagers couldn't help but harden even more at the sight of her natural Japanese features merging with hellish perfection. Her formerly thin lips plumped up into ideal cock sucking pillows. Her small nose thinned slightly while her cheekbones remained high and delicate. Her skin took on a deep purple tone while horns grew on the top of her head.
Mei ran her delicate clawed hands down her transformed body, luxuriating in the new curves the idol had blessed her with. Small hips had flared out wide. Her short legs had elongated.
Her flat ass swelled into the eye-popping heart shape the other demonesses shared. The once tame haircut she sported had rapidly thickened into a lustrous white mane that brushed the tops of those round ass cheeks. But, most noticeably, her tiny breasts had expanded into massive F-cups and were still growing.

She climbed on the top of Abe growing body and inserted his erect cock into her snatch. She howled in delight as the new incubus grabbed the globes of her ass hard and pounded into her rapidly. "Time to thanks you bitch”

Mei snarled atop him, her tits bouncing rapidly.

"Mmmmmmmore…” She hissed. “Give me more !”

She felt Karl lifting her new tail, the former innocent boy was behind his brother and her, slowly lowering himself to the humping pair. His new heavily muscled form was still the same as his twin. He now had a pair of red horns on top of his bald head; his skin has darkened even more while his dick had turned into a massive, canine-like monstercock with a pointy head and a knot at its base.
Mei purred at the sensation of his talons parting the full cheeks of her ass. He shoved most of the monstrous phallus into her ass with one thrust. The perverted student mewled at the invasion, rolling her hips back against both cocks.

Meanwhile the twins’ parents had morphed into similar demons. Trevor was now a towering mass of dark flesh sporting a massive slab of fuckmeat who was currently buried deep in her wife throat. The red-haired, dark skinned succubus looked up to him unflinchingly with her red eyes. She didn’t look upon him with love. They bore into him with desire. Her tongue lapped at his grapefruit-sized balls while her claws fondled her own immense boobs.

The incubus howled, blasting another load down her gullet right away. Marsha growled on all fours, fucking the massive prick down her throat repeatedly as she tore at the carpet.
Her back arched sensuously, thrusting her curvy butt into the air. By now, her tail had curled around and dipped into her own cunt, joining Trevor’s tail in her overheated womb.

Somehow, Dorothy was able to tear herself away from her maddening lust just long enough to look at what she is becoming. Green skin covered her rejuvenating body while her hair grew into a a mane of ebony locks. Gasping as she rubbed her clit, she saw what she was turning into. "Succubussss" she hissed through her growing fangs.
“B-but that couldn't be me ?” she said. ‘I’m... I’m still a good woman at heart ...? Right ...?” But her doubts were gradually dissolving as the burning power returns to her pussy, increasing her desire ten-fold ...

Suddenly Jebediah dragged her transforming body into his lap and pulled her face up to his. "I think it’s time to enjoy our new youth, don’t you think Honey?" he said.

"Y-Yes" she looked up to him with red eyes.

Jebediah pulled her into a deep kiss, extending his inhumanly long tongue down her throat. She feverly reciprocated, her tongue quested inside his mouth, playing around his fangs until he finally bit down, drawing her blood.

His massively swollen cock rubbed against his wife's soaked cunt, she gyrated against the muscular green demon, grabbing his tick dark horns for leverage.
Her husband was unlike anything she'd ever encountered before. Monstrous, the enemy of all she'd ever been taught. But how could she deny so much power ? It wasn't long before the huge dick rammed inside of her and sprayed her full of black cum. Her screams were muffled by the thick tail he showed in her mouth.
The duo of rejuvenated demons looked at Lydia thankfully, their red eyes with their slit pupils pulsing from the newfound evil within. Dorothy bounced rapidly on her husband's monster cock, her tight cunt sucking at him for more of his evil spunk.

Lydia answered with a wicked smile while riding Marcus. The fat, lonely man was turning into a dark-blue Adonis with a pair of ram’s horns. He snarled at the wanton demoness riding his lengthening cock. Digging his large hands into her plush ass, Marcus howled with pleasure while flooding Lydia’s womb with a torrent of black sperm. "OHHHHH, FUCK, YESSSSS," the succubus hissed in a husky, sexy voice as she came again. She turned her head to the side, opened her mouth, and stuck her tongue out as far as it would go. Next to her, Mandy responded and wrapped her own tongue around it, the two tongues twining together and rolling sensuously in concert.
The stripper now had a body that surpasses even the sexiest strippers in town. She was changing from a busty lean temptress to a curvaceous and utterly desirable red-skinned whore that screamed sex. She groaned in sheer delight as her pussy tightened, clamping down around Jim’s enormous horsecock, her moans were matched by those of the red-skinned incubus beneath her. She curled her tail around his waist, urging him to fuck her harder.
The janitor’s hands roamed greedily over her transformed body, clutching at her massive breasts and twisting her nipples. All of their old beliefs and morals were wiped away. They were replaced with a total, all-encompassing need for sex and corrupting innocents. They now had a life of never-ending perversions while their souls were burning in Hell, fueling the idol’s power.
An eerie mist had descended upon the building. While its exterior remained the same, the interior was reshaping itself to better suit its new owners. The apartments turned into large rooms dedicated to various acts of perversions.
The walls of the main room were covered in rich, thick red velvet. The room was lit by tall torches and all of the aspects of Lydia’s former, human existence were gone. The floor was covered with black, leather pillows and various sex toys were scattered about the room. The idol was in the center of the room, put on a large altar.
Lydia smiled as the idol was explaining to her the new power of the demonic nest. The rooms could change into something different while the walls were emitting powerful pheromones that could enflame someone’s libido beyond all reason.

“I think we’re ready for our next move” she said while she watched the demonic orgy all around her.
