An old friend submits

More than twenty demons kneeled reverently to their new mistress, the massive cocks of the males touching the floor and smearing it with their black cum. Their mind was as any other succubus and incubus, with one key distinction.

Devotion to their new mistress. To Lilith, the former Alexa Li.

"Good", she spoke with an otherworldly voice, every word like honey to their ears. "You will be the heralds of our new age. Together, we will show the joys of Corruption to all. We will liberate them from their useless morals and introduce them to a life of pleasure." The demoness stopped for a moment to accentuate her next words with a dash of magic.

"Under me." The new converts gasped as they saw a symbol being drawn with black ink in their right wrists. The symbol that marked them as followers of Lilith and no one else.

"Wherever you go, you will carry my sign. You will keep your free will, as long as it coincides with my own goals. Which are simple." She seared the command in their minds.

"Corrupt. Everyone"

They didn't need more encouragement. They could only think now about how they would fuck their friends, their families, their neighbors and complete strangers until they too knew the glee of serving their mistress.

The Succubus was about to continue, when a conmotion was heard outside the waiting room. A woman, no, another succubus trying to get in. A familiar voice to Lilith. Her own corrupter, Doctor Amelia Simmons.

She smiled, deviously, as she ordered to let her come in.

"This is ridiculous. Why couldn't I...?", the newcomer trailed off, as she saw the mass of demons kneeling, facing...

"Alex?", she said, stunned. Doctor Simmons had taken her human form, with blonde silky hair covering one of her light blue eyes. She hadn't forgotten to include improvements all around, her doctor's outfit barely able to keep her new curves.

But those improvements were nothing like the ones that Doctor Li had received. In fact, she would have been almost unrecognizable were it not for her distinctive almond-shaped eyes.

"So glad you could join us, Amy", Lilith said, calling her friend by her nickname. Her voice, however, was anything but friendly.

"I never got a chance to thank you for your gift", she continued, taking a few steps to face her. Despite being quite a few inches shorter than the blonde before their transformation, the Asian looked considerably taller now.

"But... how did this happen?", Amelia asked, hesitantly. Her friend's pheromones were already taking a toll at her, and she fought hard to not just fuck her in the spot.

"It would go over your head, dear", Lilith said, caressing Doctor Simmons hair and causing a shiver in her, filling her with the sensation that something very wrong was about to happen. "But I might share a little bit eventually", she whispered in her ear.

"Once you're my pet."

In a split second, the demoness split her cock-tipped tail into two before ramming them into the blonde's lower holes. She shrieked, unable to tell apart pleasure or pain anymore. Her attempts of resisting were futile, Li's strength too much compared to the one of a simple succubus.

"Dear, you should know this by now. It's easier if you let go", she said, while increasing the thickness of her tails' cocks. Amelia howled, her resistance disappearing with each thrust. They continued for a while, with the blonde losing herself into the sexual frenzy and going back to her succubus shape. All around them the other demons had taken to fuck each other again, beguiled by the amazing spectacle.

"Why... Can't... I... Cum...?", she asked, with what little composure she still retained.

"Because I do not want to. And you need to learn that from now on, you will do only what I want", Lilith said mercilessly. She was enjoying this almost as much as her victim, but she could hold until she had made her point. "Is that clear?"

Doctor Simmons remained silent, unwilling to relinquish her independence. But her old friend was filling her mind with promises of more, of pleasure never-ending, if only she agreed to her reasonable terms.

She simply couldn't refuse.

"Yes! Please! Please, be my mistress!", she begged, devoid of her previous confrontational tone. She really wanted what she had asked, at her very core she now only desired to submit to her old friend.

"I already am", she returned, climaxing in unison with the other demons in the room. The corrupting essence filled Amelia, giving her just a small taste of Lilith's power, improving her body in subtle ways. And, almost inadvertently, marking her wrist with an unmistakable symbol.

Her mistress had taken the better part of the deal, however, as the submission of an already converted succubus filled her with confidence. And with the certainty that, soon enough, all other demons would submit to her as well.

But first, two hundred souls in this hospital awaited their own liberation. And in Lilith's mind, a plan was already brewing...
