Later

The last few hours had merged into a haze of constant lust and pleasure and orgasms in Samirah's mind.

She and Nick had fucked in every single conceivable position, she had felt him paint the walls of her womb with seed, had devoured his massive prick with avidity until her throat was massaging it ; she had discovered the wonders of having her asshole squeezed around a shaft, of dominating and being dominated, of riding him before being fucked on all fours like a bitch ; she had sat on his face until he made her squirt everywhere, had been double penetrated by his massive cock and his versatile tail, had wrapped her knockers around him and basically had explored every single erogenous point their bodies had.

The result was that, even as powerful lust demons, they were beat. Worn out. Spent. After hours of intense and exhausting sex, they had ended up nuzzled in each other's arms, just savouring the electrifying contact of their naked skin, and the peace that being together brought them.

The sun was now setting and they were silently enjoying the Golden hour through Margaret's beautiful view, doing nothing but savouring the other's company.

The door swung open and the Mistress entered the room, filling it install with her magnetic presence."I trust you kids had your well earned fun ?" The question was of course purely for the form as the room's air was heavy with musk and the furnitures covered in fluids.

"While you two lovebirds were goofing around, I actually did some work to make something out of this chaotic fuck fest," she bragged a hand on her hip, "and I would appreciate if someone could come admire the result because let me tell you, I deserve a goddam medal."

She turned around not waiting for them. Not that they would even envisage to disobey her. They reverted back to their human forms and quickly got dressed in the elevator, as Margaret caught them up on the last developments.

"…and so I planned to use that pure corruption I got from turning dear Nick here, to contaminate the whole water network of the hospital. It almost took all morning to gather enough of it, but when you went for lunch I had already begun pouring it in the pipes. It was extremely diluted of course, so I didn't expect anyone to be transformed by it alone but my my, did you came on point Samirah".

"Me ?" Samirah grinned, seductively leaning on the wall without even realising it. "How so ?"

"You were such a pure soul, so prude and honest and faithful that turning evil made a backlash that sucked up every fragile soul of the building. You corrupted hundreds of people in mere seconds, you should be proud."

She bit her lip and circle her finger around an erected nipple. "Sounds hot…That's why the ward was a hell brothel by the time I came back ?"

"Yes, and also why I had to work quick to avoid unwanted attention". It didn't sound like a reproach, more like a self-congratulation.

The doors opened on the lobby as they finished buttoning their clothes. Stepping out, they looked around trying to spot the changes their boss talked about with such pride, but everything they saw seemed pretty normal for a hospital. People were waiting, hostess registering patients, some occasional nurse or doctor strutting down the corridors. What exactly was there to see here ?

"Don't look with just your eyes…" Margaret whispered, putting her arms around their shoulders. "You're not human, you're demons now."

Samirah breathed in and closed her eyes, looking for a sixth sense that wasn't there before her corruption, trying to find it in the midst of her horniness.

It started as warmth on her face, a metallic taste on her tongue and a little undefinable something that brutally blossomed into a pull in her chest. There ! The nurse that just passed them, she was corrupted too. And the hostess…no hostesses, they had all been turned ! And the nurses, all of them ! She opened her eyes and met Nick's impressed gaze.

"Is the whole hospital under the influence of the Idol ?"

"Ding Ding Ding ! What you're looking at kids, is a way to turn every sick people and their family members into loyal servants of the Abyss. We will eradicate illnesses and ageing in no time, while helping our Lords' power grow. Let me give you a tour !!"

She pointed at the desk where camouflaged succubi were pretending to fill out some useless paperwork. "That part is pretty boring, it's just there to keep the appearances until the city is ours but I figured it would be best to not leave the front desk untainted." Samirah distinctly saw a secretary shredding filled forms right after the patient, an old lady, had left.

"The bathrooms have changed a little since last time, I think you'd find the trip quite…enlightening…" she giggled before leading them to the X-ray room.

A woman was standing in front of the machine when they got in, the technician behind the protective glass and about to press the button.

"The material has been corrupted too, "she whispered, "Now it emits the same corruptive light that bathes the pits of Hell where our Lord dwells. One shot is not enough to change you, so most of the patients go back home to their families without resizing anything's wrong, and after a few days of temptation..." Samirah bit her lips imagining all those families corrupted from the inside.

"And if you amped up the dose ?" Nick asked curious.

Instead of replying, Margaret went to the technician and whispered something in his ear. He typed a bit on his keyboard, turned a few button and winked at them, a devious grin on his face. The machine began humming, something it certainly wasn't supposed to do, and Samirah faintly heard ominous chants and moans of pleasure for a few seconds.

Immediately after the woman fell onto her knees with a groan of pain as her body began to spasm. Her breasts surged forward and overflowed her bra so fast it snapped and flew across the room, her moans turned to pleasure as her ass expanded too, splitting her pants open. She fingered her hungry pussy, squirming on the floor with black fur swiftly covering her skin, two large bat wings sprouted on her back and after less than 30 seconds, she came with scream of ecstasy. She then hissed at them through her vampire fangs, her eyes completely red and leaped at the technician to furiously make out with him.

"We get interesting results sometimes…" Margaret commented as she pushed the door, leaving sounds of frantic sex behind them. "I hope I will be able to continue doing experiments once the city has fallen."

She then led them in the higher floors, providing commentary for all the modifications she had brought to the building. How cancers were eradicated in mere seconds, how patients on the verge of **** were brutally brought back, how old and senile people gained back their youth and vitality, how every imperfection of the human body was swept away like a mere dust speck. Each part of the hospital had been repurposed and refined, nothing was left to chance. It was impressive. Very impressive. A complex and efficient system designed to leave no escape to its victim, no one who'd enter here would leave uncorrupted.

"What about Pediatrics you may wonder ?" she continued as they reached that particular ward and pushed the door open. "Well see for yourself…"

They were greeted by the sight of several children running in the corridor, chasing each other probably playing tag or something. Even though sick children don't tend to play much, that wasn't really something unnatural . Were they illusions ? To keep parents oblivious ? Or-

Upon seeing them, the kids erupted in cheers and laughters, and one after the other shrank and transformed into gremlins, pixies and other small mischievous creatures that immediately proceeded to scatter in the vents or for some of them inside the walls. Creepy laughs and hisses echoed all around them.

"The Idol has use for every one, even those who haven't reached sexual maturity" she continued, "And those little monsters will prove useful when the ennemies try to stop our progression. Trojan horses, sabotage, spying… They have been cured from all their illnesses and will serve our Lord forever."

While Samirah couldn't help but be impressed by her mistress ingenuity, a word caught her attention.

"Ennemies ?" Everyone was falling prey to their corruption, even herself didn't last more than half a day. Who could pose a threat to them ?

"Yes sweetheart" Margaret replied as they left the chaotic mischief of the ward behind them, "Forces of Holiness and Purity. Envoys of Chastity, of Piety, that would rather see the world deny its desires and stagnate into a haven of boredom dedicated to worship a lying god. They're the one who stopped our Lord the first time, and delay his coup on this realm. But never again, we'll all make sure of it." She stopped before reaching the floor lobby. "You ; will make sure of it."

Her mistress gaze burn into her soul, or lack thereof, and she kneeled before her, suddenly feeling the connection linking her to all those who had fallen to the Idol's corruption. They were its progeny, its soldiers, its heralds. A phrase popped into her mind, from where she did not know but it was important: They were Legion.

As the cat lady dissipated her clothes like a cloud of smoke and pushed Samirah's head toward her crotch, to which she eagerly replied by sliding her tongue all over her folds, she vowed to never let anyone threaten that heavenly hell on Earth. Not. Anyone.
