Initiate her into the sisterhood.

The resourceful human is reduced to quivering jelly in your presence. She is completely yours.

"Please...I beg you..." she stammers.

"And sssso you sssshall, Raven," you hiss. "That sssshall be your demon name!"

The raven-haired beauty presses against the wall in panic, frantically looking for an escape route. Jenny reaches for her with wicked talons, barely missing her leg as she leaps into a stall. Her flight for the ceiling ventilation grate is caught short by your grasping talons, as you catch the belt around her jeans. Her attempts to wriggle free only guide your talons further into her panties and flesh.

"Aaaahh! Stop!" The pain of having her trou forcibly dropped and her hips and thighs lacerated is quickly abated by your sinuous tongue along her ass cheeks.

"Ssssuccubussss," you rasp, driving your salivating tendril deep into her slit.

"NNNNOOOOO!!!!" she cries out, bawling from the realization of her damnation.

The grate pulls free as you and Jenny pull her back down. Both your tails plunge inside her twin netherholes as you decimate her clothing and discard her glasses. Her naked form dangles between you as you forcibly exit the restroom, crushing her eyewear under your heel en route.

"Where...are you...taking...me...?" She barely has strength to breathe, doing so in between moans. Her legs and ass tingle with the knitting of her wounds, not to mention the vibrations of two demon tails.

"To show you your future, ssssuccubusss," Jenny grins wickedly.

The three of you press against the massive gym window, with Raven's bare breasts jammed painfully up against the glass. Within, almost forty mortals achieve the damning orgasm at once.

"Dana...Misty...Jonathan...Yvonne..." Raven whispers, crying out for her friends as they develop horns and tails and wings and lose their minds and souls to lust. With each name, her voice becomes more strained, until even she is unsure if she calls to friends or to nocturnal lovers.

"You're going to change, just like them, Raven," you snarl menacingly into her ear as you tweak her nipples, "and be mine forever. Doesn't that sssound perfect, sssslut?"

Raven's own frothing climax follows suit, and with it, she abandons herself to the flowering evil passion. Her tongue dances within your mouth as she crushes your breasts and coaxes Jenny's tail from her anus into her snatch.

The newborn demons and demonesses initiate flight into the dark sky, abandoning the Center en masse as mortal authorities begin bashing the doors in. You and Jenny follow suit, wrapping your fledgling conquest in the coils of your tails as you take wing through a skylight. Raven eagerly sucks and grinds against the tails in her mouth and pussy that suspend her over a fatal fall and between her captors as you and Jenny take wing.

The others spread across the city, in defiance of quarantines and roadblocks, to spread their gift further. You set down upon an elevated radio tower to savor your catch.

"Mistress," Raven groans, diving for your crotch upon landing, "please let me eat your pussy, Mistress!"

You chuckle and grasp the back of her head, shoving her roughly into your hairless quim as Jenny eats Raven out from behind.

The three of you rotate positions and techniques undisturbed for hours, right up until Raven's shuddering orgasm.

"Awaken, Raven!" you shout to the heavens. Raven throws her head back with the euphoria, gazing upon the world through burning crimson eyes.

The ex-human girl's skin reddens quickly and deeply. She moans in a deep heated growl as black nails curve and carve into the steel plating. Thick gobs of saliva run from lengthening fangs, retrieved by a dividing and curling tongue. Tits and ass bulge and inflate to sinful proportions, while her new globes cap with tantalizing black nipples.

Jenny's tail has her way with the transforming woman, even as Raven's extending appendage drills into Jenny's anus. She lowers her head with the agony of puncturing horns and twitching ear points, bracing herself for the flourish of her wings. She roars with unholy fury as they unfurl, joined by a discharge of thick demon cum from her bare slit.

Raven the demoness respectfully bows before you. "Missstresss, command me."

"Rissse, sssissster," you urge, and she does so, into a foul three-way kiss.

After the brief pleasure interlude, you look down from the tower to see what you overlook, hoping to find something (or someone) instrumental to your dark mission.
