The hospital turns into a den of Corruption

With more than twenty demons at her command, Lilith knew it was time to make use of her powers to corrupt the hospital at once. St. Adelaide's Clinic, as an medical institution exclusively for adults, provided her with plenty of subjects to turn into her beloved servants.

"Each of you will cover the exits and main rooms. You will know what to do when the time comes", the succubus queen instructed, before turning to Amanda, her old friend turned thrall.

"Amy, you will be gifted with the most important task of all", Lilith said as she walked to one of the punctured water coolers and inserted her two-tipped tail, filling it to the brim with her enhanced corrupting cum. Once it was full, she took the tails out and repaired the container, the liquid within looking black as pure petroleum.

"You will take this to the maintenance room and spread it through the ventilation ducts, which circulate through the entire hospital. Do not fail me", she ordered, before touching her lips with her own, barely kissing her, but with the promise of so much more if she succeeded.

She didn't need to say more. Everyone had their assignments. Everyone knew the role they had to play to achieve their ultimate goal. The corruption of the entire human race.

Lilith walked through the aisles in her improved human form, her bountiful breasts jumping with each step. The clacking of her stilettos was the only ominous sound that could be heard in the aisles, the silence before the storm.

She reached the Hospital Director's office and entered without hesitation, startling the clearly stressed woman that was shifting through papers, trying to make sense of the chaos brought by the Lilith Strain in the world.

"Doctor Li? What happened to you? What...?", she was interrupted by a stream of black seed coming out of the succubus newly appeared tail, straight to the director's mouth. The woman opened her eyes wide open in surprise, before relaxing them as the liquid made it's effect on her. Lilith didn't bother with a second glance at the director, who was now trying to lick every single drop out of her soon-to-be mistress.

Instead, the succubus headed to her desk, where the hospital-wide microfone resided. She could already see a grayish steam come out of AC system, which meant that her plans were already in motion. She wouldn't waste a single second more.

"Attention!" Her voice boomed through each room of the hospital, still as seductive and commanding as ever. "Patients and Staff of Saint Adelaide. You don't know it yet, but you have begun to walk a new path today. A path of release, a path of liberation from your pathetic old lives." She could sense the patients in the next room being affected already by the corrupting smoke, some of them even removing their rapidly constricting clothing as fast as they could. Next to her, the director was well on her way to becoming a full succubus herself.

"I will not grant you a choice to resist. I would not allow you to deprive you of the endless pleasures that you will enjoy serving under me". Lilith heard moaning coming from different parts of the hospital, their mind already linking to the Succubus. A fireman thrusting his new massive cock into the woman he had just rescued. Two impossibly beautiful sisters were fighting to see how would get to suck their brother's dick first. A full-blown orgy was taking place in the meeting room.

Their transformation was inevitable. Already the director had turned, and was submissively lapping at Lilith's pussy. "So, my dear pets. It's time for you to give your souls to me. It's time for you to become perfect."

Climax after climax, all of them finished their unearthly transformation, getting marked with the sign of Lilith. The hospital itself trembled as the corrupting energy changed the structure and twisted it to the most minimal detail. It would not be a mortal clinic anymore, but the base from which they would take over the new world. Medical instruments turned into perverted sexual toys, each capable of turning a human into a sex fiend with its mere touch. Every examination room turned into a chamber where captured humans would get turned into lascivious demons. And in the Director's office, expanded to take almost the whole floor, now stood Lilith's Throne Room, a testament to lust in its most primal form.

Seconds later, four hundred Succubi and Incubi crossed the doors, disguised as more sensual versions of their old lives. They had their orders.

Their friends and family awaited.
