The Library Ritual

Elizabeth watched delighted as the library's conference room began to be filled with adult women of all ages, yet uncorrupted, taking their seats in the comfortable velvet chairs. The place was already filling up more than usual, thanks no doubt to the incoming presentation of miss Kate Burton, a young novelist who had achieved tremendous success with her romantic novels.

It had been Julia who had invited her to read an excerpt of her new book, no doubt drawn to the borderline erotic storylines that her characters went through in their road to self-discovery and self-improvement.

And it had been Julia who had had the honor before the presentation of fucking the pretty and extroverted brown-eyed brunette into a deviant hard-cocked Sincubus burning with desire to corrupt her audience. Already she had adapted part of her manuscript to suit her new unrestrained self, very much aware of the effects it would have on the unsuspecting women attending.

Elizabeth's heart was beating rapidly, excited as the writer walked towards the stage in her human form, with a tight white blouse that had the first three buttons open, allowing for a nice view of her improved DD-cups. She kept a constant sly smile on her face as she observed each and every one of the fifty women in the audience, picturing in her head how in only a few minutes they would look much, much different.

"Good morning, ladies". Kate's voice was dripping sensuality while still keeping a sharp Intelligence behind it, and her buxom body was already making the most heterosexual members of the audience doubt themselves. "I thank you for joining me into what will no doubt be a time you shall never forget. For you see, you will be the first to hear an extract from my new book. A fresh beginning, this time into the realm of fantasy"

There were a few murmurs in the room. Kate Burton was known to write from a very realistic point of view. What would have driven her to change her ways?

"You see, our story begins in a library, much like this one...". The disguised Sincubus began to tell her story, where the nubile female protagonist had gone to an abandoned library, searching for clues about her disappeared wife, who was rumored to have entered a cult. At the last moment, she had renamed her character to the one of her corruptor, as a hidden reference.

"The deeper Julia went, the more she noticed that this was no ordinary book depository. The few lights that could still be lit shone red, barely illuminating against the dark stone walls. Yet still enough to notice the ritual markings, drawn with some vile black substance." Subtly, the auditorium itself began to magically change to suit the same description she had given. But Kate's voice was so captivating, so hypnotic, that no one paid attention to it.

The description continued, with the protagonist eventually reaching the building's cellar, which was empty save for the leather-covered book in the middle. "She felt her body heat up, dropping her jacket to the side as she approached the mysterious tome. But it was not just the anticipation. Something else, something truly magical was in place here. Not evil. Tempting. Lustful", the writer popped one more of the buttons of her shirt off as her breasts began to swell. She grinned, looking at how everyone in the room had their eyes glued to her and had began to follow their lead, very slowly stripping from their clothes.

"Julia doubted whether to open the book, feeling it's essence already twisting her mind into something completely alien to her. She was about to turn away, when she heard her wife's voice clearly. *Do it*, she spoke with an ethereal, immortal voice, yet still recognizably hers. *Let us be reunited, my love. But this time not as lovers, but as servants of our eternal mistress*". At the end of the auditorium, Elizabeth had made sure that the doors were completely locked before the grand event. It didn't seem necessary in the slightest though, given how no one had any intention to move away from their seat.

"Julia had made a decision. She had entered this forbidden place to get her loved one back. She wouldn't turn back, not at the very end of her road. She opened the coarse of the book by the middle and then..."

The whole library, the real one, trembled as the red lights burned brighter and illuminated a giant hidden symbol drawn in the floor. Elizabeth and all the other demonesses had used the full extent of their magic to create this invocation, and the massive surge in sexual energy at that moment drove them to their knees in ecstasy with their bodies reverting to their horned selves.

That was only the tip of the iceberg, however, as from every inch of the walls and floors surged a network of black tendrils, counted in the hundreds, manufactured with the sole purpose of defiling and corrupting. The mindless penis-like tentacles flayed around looking to fill every hole they could find of the innocent attendees, with no woman having less than 5 penetrating them at a time.

None of them resisted it, already having been influenced too deep by the mind-affecting tale of the writer, now fully turned into a hung Sincubus, with her clothes turned to shreds. "And so Julia saw her. Her beautiful, tender wife, now transformed into a beast of sex and perversion. A long, thick cock slapping against her thighs with each step, unable to cover the tight, monstrous ballsack behind it. Neither of them spoke. No words were needed. They were together again, and so they would continue to be, forever."

It was then that the real Julia, the old library manager, appeared and walked into the stage. She didn't speak either. The only thing she did was drive the celebrity writer into the floor and **** her to suck her hard Sincubus dick. She watched as the audience was already showing late signs of their corruption, moaning deliriously as the tentacles fecklessly penetrated them. The eldest had lost their wrinkles, the obese were missing their extra weight. And everyone, everyone, was now sporting a full set of horns and tail that marked their corruption.

It was no surprise to Elizabeth to see how many of them were growing cocks of their own, the sign of true potential against demonesses. It was to be expected to find the hidden roots of repressed sexual energy in this group of dissatisfied housewives and college girls.

Elizabeth screamed as she absorbed once again the power of her corrupted victims, allowing her to change once more. Her purple skin was getting covered with magical bright green runes enveloping most of her body like a snake tattoo. And her body itself was reshaping once again, standing at 6'5'' with firm muscles and a tight six-pack. She used its magic for one more transformation, essentially growing a new foot-long cock above the former, while enlarging her balls to the size of oranges.

Her eyes shone bright green now, and she felt the ability to control minds and matter with only a flicker of her hand, with a sparkle of green energy jumping from her fingers towards Julia to reward her with an improved body as well.

"And so ends the story of Julia", the Sincubus mistress spoke telepathically to each one of her new servants. She could already see some of her co-workers' family members and a few acquaintances of her own among the new harem members. "But for us, my pets, the story is just beginning. Isn't that right?"

"Yes, mistress!", the gorgeous demonesses screamed out loud as they continued to fuck and be fucked, embracing their new identity as sex slaves at the service of their benevolent leader.
