The tiger sighed, perched at the dining room table, though it didn't really feel like "her" house at all, not as yet. It was strange for Gale to be there, the sense of emptiness swallowing her up, the house more of a lodge somewhere between a family home and a gamekeeper's cottage than a house that she would ever have considered actually living in herself, the windows rattling where they no longer fit securely into their frames and the floorboards creaking when Gale moved.

She poured over the contract again, but she had signed it and taken her chance, even if she did not believe it true, studying it with the slits of her feline pupils, tail swinging lazily around the legs of the chair. The house had been left to the last female descendent of her family before the turn of the millennium...why ever that was...by some great grandmother of hers. Gale frowned. What was that -- seven generations back with all the "greats" in there?

"But why leave it to me?"

The empty room had no answer for her, her belongings appearing too small for the aged grandeur of the property that, for its age, was still kept in good condition. Apparently the estate management company that had kept it for so many years had renovated it every ten years or so, though there were still a few things that slipped through the gaps: it was not as if the floors or windows, of course, were going to be replaced every ten years when there was nobody living there and that was something they had assured her could be done in line with the original contract as soon as she made a decision on what she wanted. Gale didn't even have to pay for it.

Yet the house was isolated, down a long, dark driveway with a gated entrance, a heavily wooded park surrounding it so that it appeared entirely cut off from civilisation. It had everything she needed there except for company and, when she had taken the time to attempt to speak to the nearest neighbours about it, not letting on that she was the one who would be moving in from her dinky apartment that cost too much anyway, they had shrugged her off.

"Always feel like I'm being watched up there, just going past the gates," the mouse had said, wringing her paws and eyeing up Gale distrustfully. "It's a strange place... What do you want with it?"

Gale had made up some excuse, some college project, though she was a few years past that. Her interest in curiosities and research, however, had not faded, which was perhaps just one of the reasons that she had been drawn there, eventually, ensuring that all the paperwork was in as good nick as possible with her lawyer first. She didn't want to be caught out, after all...

Gale sighed. There was no sense in pondering and wondering what was going on, especially not on her first night there, the living room light anything but comforting. It was too bright, too glaring, for its surrounding and she only had the stomach for a light meal before retreating to her bedroom and a moderately old-fashioned four-poster bed that still held an air of grandeur around it. It was comfortable enough with a modern mattress, however, that she sank into it in no time, hardly able to believe her strange kind of luck in finding a place to live that, at the very least, meant that her savings would last for a good number of years while she amused herself. In that way, she had time and space to work out just what she wanted to do with her life, which was all that any young femfur so often needed, even with the troubles of the world pressing in so urgently around them.

It was not a huge home by the standards of detached homes that she knew of in more affluent families and friends but it would do for her, more than she needed. Her eyelids grew heavier and heavier as she snuggled under the strange sheets that she was sure would become more comfortable and familiar in time, she slipped into a light, fitful slumber.

Those that had said they were being watched in the property, however... They would not have been wrong.

The sentinel stirred. Gale tossed in sleep, the first rays of dawn cutting across to the bed where the curtains had not been drawn the night before. The tigress rubbed her eyes, yawning widely with a stretch that was inherently feline in nature, her blonde hair falling across her face as she grumbled and pushed it back out of the way.

But something was different -- just the one thing. It could not be missed, however, the massive, bound tome sitting on the desk in her bedroom, though she was not sure why she'd set up the desk there when she had enough space to have her own office or study room in the house too. She gave a strangely strangled cry as she jumped up, tangled in the unfamiliar bed sheets, fighting her way through to get to the book, fingerprints darkening the surface where something, or someone, had placed it there.

"What in all hell..."

Gale trailed off. There was no one there to answer her, as much as her heart pounded. But the dust-covered hardback with a finely carved cover told a tale as old as time, surely over five-hundred years old at the very least. Gale gulped, leaning in, hardly daring to touch it, not yet. For it held more secrets than even her research, so far, had illuminated her mind.

It wasn't just a book... It was a Grimoire. And that very fact should have terrified her more than it excited her, sending her heart turning over, mind darting to the books she had brought with her, books on magic, strange happenings, things that the world passed over without evidence. Yet she had studied and dug into that side of the world, delving into the passions of history and, her personal penchant, transformation, fingers reverently tracing the cover.

Maybe it had been left to her by her relative. She brushed away any worry. Either way, she would investigate it.

"Goodness..."

She forwent breakfast, too keen to see what secrets the book held to wait. Setting it up on the desk, she only dressed herself lightly for the day, pouring over it, the script inside from another time and age but still in a language that she could understand. Old Magic. Olden Times. There were many names for it as she traced the lines of script with her fingertip, mouthing the words as she sounded them out loud and translated them in her head. What was more helpful to her, however, were the notes and additions noted in the margins of the book in Olde English, which, while difficult, was still easier to read, her breath caught in her throat.

It was like stumbling into one of her greatest fantasies, the images sending her heart pumping, lungs so tight that she could barely breathe, hardly snatch a breath. The tiger stilled and stiffened, images of female furs and males alike -- some ambiguous or other sexes -- with strange, strange body parts catching her eye. If she didn't read the text at all, the descriptions of spells and erotic effects that had her heart pounding and her thighs squeezing a little more tightly together all over again, the images would have told the tale in full regardless.

A succubus leered from the page, a tongue spilling from her long, elongated maw, multiple pairs of breasts on her chest and stomach. That was the most normal of the images as she turned the page, finding a female shape with penises jutting from her shoulders, another with a set of balls and a cock protruding from their throat. Some of the humanoid figures and shapes could not be discerned as either male or female but Gale still kept turning the pages, finding multiple cocks all squeezed from the same sheath, balls so large that they dragged on the ground, everything to weigh down the "poor" victims in innovative and strange ways.

Gale gulped and squirmed. She shouldn't have been as aroused as she was by the book and yet she couldn't stop looking. Maybe her family had had strange interests as far back as her ancestor and that was why such a book had remained her family in such a strange way?

There was no way to tell, not even as she groaned and rubbed between her legs, her thighs spreading to allow her paw inside. As she paged through, reading some descriptions and heating up her prickling skin even more, Gale gulped, the transformations growing increasingly extreme. Not just one or two strange or large body parts anymore and no more simply changes to arms or legs, enlarged tails and the like: the transformation depicted in the old spells would have weighed down a fur into a groaning sex freak if they had been true. She lingered on one near the end of the book with a definite female fur on her back, cocks jutting out of her nipples, multiple protruding from one nipple, all appearing equine-shaped. They were more than large enough to weigh her down, her breasts squashing and flattening under the sheer weight of those cocks.

She turned the pages faster and faster, every change to the images exclusively sexual. Females with huge breasts for their buttocks, seeming to leak milk, large enough to keep them in place until the end of time. Gale's juices flowed, tickling and gleaming on the soft folds of her pussy, paw shoved into her underwear just to feel, just to tease. The humanoids later in the book proved to be differently laden to the extreme with configurations of breasts and cocks especially that would never be normal, whole backs covered with dicks and balls while breasts layered thighs, huge and heaving.

The last pages, however... There, she paused to read. Those were curses, her brow furrowing as she sought to understand just what they could encompass. Some there had their arms or other limbs replaced by breasts, faces a single, huge breast, complete with nipple, the ability to use their senses stripped from them, presumably, by the curse.

Gale had to eat at some point but she spent the entire day pouring through the tome, a notebook beside her to jot down spells and pages that she found particularly interesting. It was a credit to her that she did not take the time to get off, too wrapped up in the book to care about even her own carnal needs, pushing on and on, just wanting to see all that it contained. The book covered basic spells, such as simply changing a target's sex or changing the size or shape of their genitalia, from moderate spells like species changes and vaster attributes to, of course, the extreme transformations and curses that caught her attention the most. Those were something that she could pour over for weeks, an unholy grail of material to feed her fantasies for a lifetime and more.

"The...climax will last...for days..."

She murmured, translating a difficult passage. Did that mean that the size of those balls would render the target climaxing for days literally? She gulped, licking her lips, a tingle shooting through her. Fascinating...

Others for disfiguring and reducing the physical ability in merely living, oh... Oh, she made the most notes there, on those spells especially. Many spells, the curses, were intended to cripple the target with huge sexual organs, whether that was in simple size, placement or the number of them -- covering an entire head with cocks and pairs of balls, for examples. The tigress' tail flicked and curled back and forth, moaning softly to herself.

"Ohhh..."

Gale shivered.

"Most Potente Curses... Have Care."

Losing senses to sexual organs, a tongue becoming a cock, more bursting from the cheeks of a fur engaged in a transformation sequence... She squirmed delightedly. It was too much for even her to bear in the delirious delight of it!

She didn't eat that day or get anything that she wanted done, though if she was there to indulge herself, studying her favourite topic in the world was the best thing that she could have imagined doing with all her spare time and money. She slumped over her desk with her paw protectively on the tome, her lusts empowered, wet between the thighs as if she had gotten off many times over, though she could not remember, not even when she woke around noon the following day.

She could have gotten up, could have gone to eat, but it didn't seem to be what she needed in that moment, pouring over the tome, her loose trousers slid down so that she could better feel her pussy, how her thighs pressed in lightly against one another. She squeezed down around nothing, though the rumbling of her stomach grumbled more and more urgently.

Gale sighed. There was still unpacking to do, food to eat, her mind wandering, imagining just how it would be to go about her daily tasks with cocks for fingers. Would they be just as sensitive as a dick? Would they be able to drool cum? Oh, she would have hoped so, though that in itself just made it all the more alluring to wash the dishes. Soapy water flowed between her fingers and she panted heavily, trying to do everything that she needed to as quickly as possible, all to get back to her book, the wonderful Grimoire, trembling with need.

However, there were better things to spend her time on, if she dared, even if she could not expect it to work. As much as she longed for magic to be true, she was not so sure that using it as an explanation, in some of her historical documents, for someone leaving the house and returning as another sex. In the same vein, she did not expect the spells to work even as she stood before the mirror, her chest rising and falling with a little more passion than expected with every breath.

She needed it, needed to try. Just for her own arousal, her fantasies, her naked body beautiful in its striped presentation. She moaned, trying a spell, first of all that was supposed to enlarge a very certain piece of her anatomy. Well, they were out and on show.

"Ohhen simmeratus overon breattits..."

She was sure her pronunciation was terrible, but she saw, in her mind's eyes, her breasts swelling in response to the spell. It was meant to make her breasts grow larger by increments but she wanted to push it on too, her thighs rubbing together, wanting more, unable to think about anything else even in a moment like that.

"Perratus yvonnia havatas curiossion..."

She didn't know what she was saying, only that she had to keep going, following another spell that would give her a male shaft -- in the expected place to begin with. Gale shuddered and moaned, fingers trembling so badly that she could barely hold the tome steady, her free paw running over her crotch.

She could feel it swelling, matching the imagined heavy weight of her breasts, how they sagged down, nipples tugging down as if to put themselves even more on show. To have a shaft there, however, was not her fetish and fantasy and she clumsily read out another that would give her larger breasts again still, the moisture between her thighs increasing with every spell.

Gale imagined it all, the swelling of her tits, imagining that the spells were making them large enough to drag her weight forward, hips pushing back instinctively, so deep in the fantasy that she could not extricate herself. One pair was not enough and she rattled off another spell, not caring for how she said it, pointing at her reflection, wanting multiple pairs, all layered down her front.

One after the other, she saw them appearing, though she was not surprised that, of course, nothing had anything more than the imagined effect. The shift of her body was something in her mind's eye only and she didn't actually have huge breasts bigger than her torso, not as she wanted to see them.

But that only meant that she could delve deeper still, a paw occasionally delving between her legs, taking on her transformations in her mind as she moaned and whimpered, hips wider in her mind. Oh, how she so badly wanted it to be real, to have cocks, like in the back pages of the book, sprouting from her hips and thighs, dotted all over her like she was a monster completely and utterly derived of fetishes untold. Before her eyes, her feminine frame shifted in the mirror (just a shift in her weight) and she blinked, wishing that, when she blinked, she would find her buttocks turning into breasts, perhaps even a dick tucked between them.

What about the darker ones? The ones that were sickening even for the curses? She read out one with bated breath that would have transformed her so terribly that she would have every limb covered with breasts, nipples most likely leaking milk too, bulging and weighing her down like a tumour. Yet it would be the most erotic of things ever, a moan rising from her lips, fingers plunging into her sex as she brought herself off to a screaming climax without seemingly any effort at all.

She glanced back, panting, the afterglow fading, needing something more. Gale's skin prickled and crawled but there was still something more, the feeling of being watched, as much as she tried to shake it off. She was alone there, she was sure, grunting and groaning, rushing through yet another spelt hat would have changed her ears into cocks, dangling and heaving, so heavy that they would have dragged her head down to the ground. Nowhere in even the curses was pain, however, noted and she relished in that fantasy of untold pleasure, how it could have rolled through her, if only the magic was real.

Little did she know that she was being watched, the guardian of the property rising, the one who had placed the tome there in the first place. A demoness lingered there, a draconic type with rippling scales layered over her skin, shifting like armour while being a part of her body too. Her jaws were extended in the draconic fashion, intelligence gleaming in sharp, blue eyes, her body humanoid and yet alluring to the male gaze, a narrow waist rising out to sharply flared hips and a wide, swinging tail. Spines rolled down the back of her head all the way down her spine, though the tip of her tail was tapered to a triangular shape.

The succubus watched, the ridges above her eyes raised, head cocked. Gale would not know she was there but the succubus demon barely thought that Gale would have seen her even if she had not cloaked her presence. The spells had called her back to the mortal realm and yet she had never expected to see a mortal writhing on the floor, moaning about how her eyes had become cocks, how breasts were bulging from her face. The tome held all of those spells and more and the succubus-dragon licked her lips curiously as Gale even hugged pillows to her chest, apparently pretending that her body had gained massive, body-destroying tits that would have kept her immobile, regardless of what her mind may have wanted to do.

Someone wanted to be cursed? Her fingers curled around the doorframe, invisible and yet present. Interesting... Shocking but not to such an extent that she would have left Gale alone.

Gale panted and heaved, finishing with a spell that would have had giant horse-shaped cocks sprouting from every orifice, stuffing her maw from the wrong side and even claiming her sight. She groaned out loud, a hot, wet, sticky mess, setting the book aside even though a part of her still longed for it, wanted to hold on for just a little bit longer. A shower was on the cards, if only to make herself feel a little bit more put together again, panting heavily as she practically dragged herself off to take care of that need, a groan rising in the back of her throat.

Late evening brought her back to the bedroom with a full stomach, skin crawling as if she was in heat, her fur tickling. There were too many sensations at play, even if she was wearing her night clothes, her pyjamas, too close and pressing in on her body as she squirmed. The mirror called her, bare paws treading carefully, the tome in her paws before she realised just what it was that she was doing.
