Anima Insecti

Twilight paced back and forth in her bedroom, not for a moment taking her eyes off of the catalyst of this whole situation. The book sat on a reading pedestal, bound tightly shut (as she did not for a moment trust it not to open of its own accord). Tonight was a time for action. Tonight was a time...for science!

At her bedside sat two curious contraptions: The first looked something like a seisomograph; its needle sat poised and waiting to begin taking measure of her brainwaves. The other was somewhat more arcane, something she'd jury-rigged together with thaumatic equipment and carefully honed spells. It was what she called a 'dream recorder', and she hoped it would record the visitation of that strange entity so that she could peruse it in a fully conscious state (and provide it as evidence for this curious case).

Last but certainly not least, Twilight had conferred with Princess Luna about the situation, and Luna had promised to enter her dreamspace to see if she could divine what this thing was.

The sun had now set, and Twilight, tired from getting very little sleep the night before, headed for her bed. She didn't relish further visitations from the entity, but she knew it would be back. And she knew she had to figure out what in Tartarus was going on. So, with a withering glance at the offending book, she got herself wired up to her devices, turned them on, and lay back against the welcoming embrace of her bed.

"Nkrru, yk xahq." There was the voice again, crooning in her ear. Twilight wanted to move, but she couldn't. Her body felt restrained in the dream, as if bound. Cocooned.

"What do you want from me?!" She demanded. At least she had found her voice this time. All the previous visitations she couldn't utter a syllable.

"Q hlye ndj." It replied, and then Twilight felt something like a long, slick tongue trailing up her neck. It made her squirm. It made her moan. It made her wet.

"I d-don't understand," she sobbed, hating that she was getting aroused. Hating that a part of her liked this, whatever this was. "Ahh..." The invisible tongue lapped at her neck, then began to trace its way down her body, matting her coat with its slimy saliva. It went lower. And lower. Part of her wished she could move so she could get away from it, to stop this eldritch seduction. But as sharp, unseen teeth began nibbling teasingly at her inner thighs, she found herself wanting it. Whining and whimpering for it. The entity just wanted to bring her pleasure. She should just...just let it...let it happen.

She threw her head back and moaned whorishly as it began to devour her marehood, her needy clit winking against the wriggling tongue that she couldn't see but could certainly feel. It felt wonderful. It ate her out like a passionate lover, lapping hungrily as if it couldn't get enough of her.

A dim recollection came to her: Luna was supposed to intervene, right? Where was she? But then that tongue slid deep inside of her and she was bucking her hips, crying out in delight. All of a sudden it felt like her bindings had been removed, and she reached down, running her hooves lovingly through a gossamer mane, encouraging the entity, wanting it. Buck, she wanted this so badly. Twilight could feel the pressure building in her belly, all that wonderful pleasure coiling in a mad spiral, begging for release.

All of a sudden, it stopped. "N-no! Please! You can't leave me like this!" She begged, trying to move her hoof to finish herself off, but finding her limbs frozen in place. "Please...please..."

"Ias lux yq, Twilight. Qvobus lux yq." The voice whispered, and she could feel hot breath washing over her sex. "Q hlye ndj zu qvobus." Again, that strange tongue that she could not understand...but the tone. It was asking something of her. Demanding something. She didn't know what it wanted, but as it began teasing her once more, she gave in.

"Yes! Whatever you want, yes!" She shouted, and immediately that tongue was writhing deep inside of her. "I'll do it! J-just don't stop! Oh b-buck...I'm...oh Celestia I'm...ahh...ahh!" It was too much for Twilight, who let out a keening cry and came all over the entity's muzzle. It kept licking, lapping up all her juices, sending the alicorn into a paroxysm of pleasure she'd never felt before. Lovers for Twilight had been few, and this...this was leagues better than her hoof or a toy.

"Lux ndj! Kqe! Q qvobus!" Twilight again awoke with strange words on her tongue, words fed to her in the dream. She didn't understand them, and yet, some deep, dark, primal part of her did. Something inside of her told her that it was an ancient language, older than Celestia, older than the hills. Whatever it was, it felt like it flowed so nicely on her tongue, despite the clicking, the hissing, the chittering...

She shook her head, sitting up and trying to reorient herself. She removed the headband sensor and the electrodes on her leg, then turned to see what sort of results the machines had recorded. And what she saw absolutely baffled her. It defied all logic. The brainwaves recorded on the graphing paper showed not a series of peaks and valleys that would accompany sleep cycles, but instead it showed brainwaves that suggested she had been anything but asleep. The brainwaves showed her mind had been in a state that was beyond hypergamma waves. "That...no, that doesn't make any sense." Likewise, the dream recorder had not recorded anything, as it was primed to do so during periods of delta brainwaves. "No, I was definitely asleep. I'm sure of it."

Frantic, she went to find Spike so she could send a letter to Princess Luna, wanting to know why she hadn't shown up. As she did so, she caught a glimpse of something in the mirror as she passed by the washroom, something that made her pause. She backed up and stepped in, looking at herself in the mirror, and gasped in horror. Fangs? Check. But now the rest of her teeth were sharp, carnivorous. And not only that, but her mane and tail were no longer the horsehair that she knew, but instead made of limp, gossamer strands. She'd only seen that kind of hair once before, and it belonged to one of her sworn enemies.

"No. No. I'm...I'm turning into..." She began, only to have her eyes roll back as she fainted, collapsing onto the bathroom floor.
