Rebirth

The single-minded need to cum was too strong, too powerful to do anything but follow it.

They immediately went after the person next to them to fuck their brains out, without even bothering to ask. Two male college students were double-teaming an older woman that could have been their teacher, but now looked rejuvenated by at least 20 years. A couple of formerly prude girls were licking each others pussies while giving a handjob to some other stranger's dick. A wife was giving his husband a titjob first time ever, taking advantage of their now increased size.

All around had instantly turned into an expression of pure unadulterated sex, heightened by Alexa's pheromones.

All but two. Natalie stared at the show, shocked, burning up in desire to join one of the multiple sex-frenzied groups. But Doctor Li was firmly holding her from behind.

"Isn't it great, Natalie? All of these people, free to do what they always desired. To fuck some random guy or gal in a room, without care about the consequences", Alexa whispered to her ear among the cacophony of moans, grunts and flesh slapping against each other.

"Yes...", she answered, her meekness replaced with a fiery need for sex in her loins.

"But you, dear girl, will get something better", she pushed three fingers into the girl's vagina, eliciting a long sigh from her. "Me"

The receptionist was able to watch as the others kept getting more raw and passionate, taking each other's holes with no regard for decency. Their bodies were transforming quicker, reforming to a sensuality that few of them ever dreamed to have. Fat and wrinkles disappeared, muscles tightened, breasts filled and butts expanded, all of that and more. Their demonic traits had yet to appear, however.

Doctor Li was fueling the secretary's transformation as well, reforming her body wherever her hands passed, leaving black veins in their trace. "More! Please, more!", she begged, unleashing a secret desire to become a perfect submissive slut. Her body was already the envy of almost every woman, but that still wasn't enough for her.

"I can give you more. But you have to do something for me first", the doctor requested. Her body returned to her succubus form, allowing everyone to see what she truly was. They seemed to go faster and harder in response, but no matter what, they still seemed unable to cum, as she had requested earlier.

"I can give you eternal life and pleasure", she raised her voice, repeating her words. "I can give you all eternal life and pleasure.

"If only you pledge your souls to me"

The response was instantaneous, without hesitation.

"YES!", they screamed out in unison as their long awaited release arrived. Black cum filled every hole, completing their transformations. Their skin turned into different shades of red, horns grew out of their temples, tongues unfurled from their mouths and tails sprouted out. Finally, their different tones of eye color were replaced with shiny pools of black. The last remnant of their humanity was gone.

The succubus leader howled as her mind was thrashed by the power of more than twenty new souls, forcing to replace more of her old memories with arcane knowledge. Her own soul was tainted beyond recognition, different from that of even a regular succubus.

She was something else now. Her horns had grown, forming a crown in her head. Her figure was indescribably sensual and her pheromones alone would be enough to corrupt others.

She was different from a different succubus.

"Bow, my pets. Bow before...", she paused and a smirk grew on her thin black lips. "Lilith"
