#1 of Sylvari's Demon


Sylvari smiled to herself as she walked down the sidewalk. She had had a wonderful time at her friends' party but she had to errands to run in the morning and left the party which was still in full swing, even at 2 am. Her departure had drawn a few protests, especially from a male cheetah that had thought Syl had been flirting with him all night and, more to Sylvari's amusement, the female cheetah that had come with the big lug with whom she actually had been flirting with.

Sylvari admitted to herself that her new red dress did an exceptional job at showing off her canine body. She was a Siberian husky and stood at 5 feet 9 inches. Her fur coloring was a traditional black, white and grey that hinted of being a purebred. Unlike many furs in this part of the world, she had digigrade legs as opposed to the more human like plantigrade feet that were dominant here.

As Sylvari continued on her way back home, a mere five blocks from her friend's apartment, she decided that the short cut through an alley could save her a bit of time. She turned down the alleyway and immediately realized that this was a bad idea. A sense of doom crept up from the pit of her stomach, but she swallowed it, determined to not let stupid, irrational fears manipulate her.

Sylvari proceeded and was half way down the alleyway when a bright, sinister flash of red light lit the alley way immediately behind her. Sylvari screamed startledly and spun to see what had happened. Before her a great rune circle of dark power seemed to swim in the pavement of the alley emitting a red glow that drowned out everything else. In the center of the rune circle stood what Sylvari immediately new to be a demon. The demon appeared to be porcine in origin with cloven hooves covered in red latex boots and gloves and stood well over 9 feet tall. Two red horns sprouted from its head and two large feathery, maroon wings sprouted from its back. Its tail curled and flicked around seemingly with a mind of its own as the evil thing turned slowly to look at Sylvari. Sylvari's attention was drawn immediately by two things; first that the demon held a huge book in its left hand that seemed to radiate darkness, second that this demon was in fact a demoness.

Sylvari had the overwhelming urge to run away from this awful sight and started to turn to do just that. However, before Sylvari could shift her weight to flee the demoness threw open her tome and muttered dark words into the air. Immediately, Sylvari felt a collar coalesce around her neck and bindings appear on her legs and wrists seemingly from thin air. The bindings felt like latex and red metal chains grew out of them. The chains from her leg bindings sought out each other and formed a spreader bar forcing Sylvari's legs apart. The bindings on her wrists grew chains that flashed out and latched on to a nearby fence pole that stood at the edge of the runic circle. The chains tightened and pulled Sylvari back to the pole that had begun to glow red with demonic power.

A red light began to spread out from Sylvari's bindings that began eating away her dress, turning it to ash as the glow spread outwards. Strange red orbs began circling around Sylvari as she fought against the strange power that held her captive. The demoness grinned cruelly as she flipped through the pages of her grimmorie laughing now and then. After a few minutes of searching the demoness found what she had been looking for and looked up at the still struggling Sylvari.

"Get ready darling, this might be a bit unsettling," the demoness spoke with a seductive voice to her for the first time since appearing.

Before Sylvari could shout a retort the red orbs spinning around her abruptly began to grow as the porcine demoness muttered a single word into the night air. Pain shot up through her feet as Sylvari screamed in agony. Her feet paws began to melt and run together reforming quickly into red, burning hooves. Her tail began to lose its natural curl and stretched out a foot...two feet...three feet...finally five feet long; halfway down her new tail dark red scale formed on the skin replacing her fur and shot painfully down the remaining length to its end as the tail tip flared out into a dragon like spade tail-tip. Sylvari's head began to pound as two large, red horns burst from her head fur to curl around her ears and ended in sharp points. Sylvari had tears welling in her eyes as the pain subsided from her body and she looked up pleadingly at the demoness.

"Hm...something is missing. Let's see; hooves, check. Tail, check. Horns, check. Wings...ah, that's what it is," the demoness spoke to herself while examining Sylvari. She looked back to her tome and muttered another seemingly nonsensical word that Sylvari, horrifyingly, understood perfectly.

Another surge of light from the orbiting sphere's signaled another burst of hot pain just behind Sylvari's shoulder blades. Sylvari opened her mouth to scream as two leathery, draconic wings burst out of her back. Her new wings stretched painfully outward to their full eight feet wings span as Sylvari's scream tore from her throat.

The pain quickly subsided to a dull, full body ache that left Sylvari slumped in her bonds, her weight supported by the pole she was attached to. She lifted her head fractionally to look at the demoness only to see it laughing with amusement. The thing spoke a last word to the orbs that fluttered around Sylvari's slumped, transformed body. At a moment each of them formed into three distinct orbs and hovered just in front of her.

The demoness flipped her tome closed and the three strange orbs rushed into Sylvari all at once. Taken completely off guard Sylvari had little time to realize what was happening as the first orb pressed into her open mouth, forcing its way down her throat and sliding down into the pit of her stomach. It seemed to burn and freeze at the same time as the orb slid into her maw changing everything it touched. As it passed over her teeth her canines became longer, sharper and hollow. Now filled with a venom that would afflict the poisoned with overwhelming lust and heat. As it passed down her throat it completely removed her gang reflex, lengthened her tongue, and split the end into something more lizard like.

The second orb expanded and encompassed both of Sylvari's breasts sinking into her fur and skin and pressing its way into her body through Sylvari's nipples. Her breasts expanded shredding her bra as they grew outwards two full cup sizes from Sylvari's original B cup to D cup. As the orb sunk in further its energy sank into her scent glands rewiring them to produce an extremely potent pheromone that would attract any female and seduce them with smell alone.

The last orb sunk into Sylvari's nethers, squirming and sending sparks of ecstasy racing through the husky. The orb sunk deeper and deeper changing Sylvari's screams of pain and horror into moans and gasps of delight and pleasure. The orb slid deeper and deeper simply passing over her deeper folds and exciting her as it seemed to fill her and empty her all at once. Sylvari moaned as the orb vanished from the surface of her body, only revealing that it was there by a strange red glow emanating from her slit. The orb slid past her cervix and finally found her womb and ovaries and set about transforming her femininity. Sylvari's ovaries morphed to producing demonic eggs that would corrupt any female they were laid in while her vaginal muscles became much more powerful and granting Sylvari exquisite control over them.

Sylvari herself screamed in disappointment as the pleasure and ecstasy faded from her body all at once. Leaving her teetering on the edge of climax but completely unable to find release. She struggled to bring her fingers to bear on her needy sex or to at least rub her legs together but her bonds prevented that and she was forced to bear the utter lack of satisfaction as her body began to lose the feeling altogether. She screamed and cursed at her body and at the smiling demoness before her as the ecstasy slowly, excruciatingly abandoned her.

Sylvari slumped forward again, letting her bonds take up her weight as her voice had run ragged and she began to feel empty and twisted inside.

"Why?" Sylvari croaked at the demoness.

"Why not? I needed a new minion on this plane and you just happened to be here. It is nothing personal, I assure you, dear. However, I do think that the females of this world need a little something that I can provide...through you of course. And if I read your thoughts correctly you already like screwing females anyway. This could be fun for you if you just accept it," the demoness explained nonchalantly. "No one but a sexual partner will be able to see this form, if that's what you're worried about. And you'll find it much easier to find such partners thanks to the modifications I made to you. I'd do all this lovely corruption myself, but this plane is toxic to my kind if we stay her for longer than a few hours. Hence yourself, my lovely new minion.

"Now, for the fun facts of your new body. You need to mate with at least one female a day...I don't care if its feral, anthro or even one of the few humans left around. Your body will know what to do and if you need me," the demoness snapped her fingers and a strange rune appeared in Sylvari's wrist bindings. "Just tap those runes twice and call for me, I'll appear before you. Any questions?"

"T-t-take this a-a-away," Sylvari mumbled desperately.

"Oh, I'm sorry. The change is irreversible. Remember what I said and don't try to resist your urges...they'll become most unbearable. If you do a good job though I'll be sure to reward you properly. Ta-ta, honey." With that the porcine demoness vanished taking with her the bonds that kept Sylvari tied to the fence pole.

Sylvari still sported the collar and bindings but no longer had the spreader bar or chains keeping her restrained or supported. Sylvari slouched to the ground and had to force herself to raise her head slowly. Her eyes were much keener than they had been a few short minutes ago thanks to the demonic enhancements and Sylvari saw the alleyway as if in broad daylight. The new husky-succubus looked around and slowly dragged herself back to her apartment and fell asleep just inside the doorway. Even in her exhausted sleep, new, dark dreams assailed her mind and left her with a need that stirred deep in her transformed loins.
