(M to Rat)

Kyle hated dentists, much as any sane person would. There was something about their clinical fascination with teeth and their unbridled sadism that put him on edge. So naturally, when he found an ad that promised an end to dentists, he enrolled in the study. It was simply civic duty.

That brought him to this very moment, one where he regretted everything he’d done in his life that led to this mistake. Across from him was a bona fide dentist, freshly failed out of real medical school.

“Hi!” The man waved. Even his voice was irritating, a chipper tone that was either faked or a genuine simpleminded happiness.

“Hi,” Kyle forced a smile onto his face. “Um… Is this the clinical study for dental hygeine?”

“Not even in the slightest, I’m afraid. This is the NSADA study. Never-See-A-Dentist-Again,” the man explained, as though he didn’t mind the fact that the study would put him out of work.

Kyle couldn’t help but ask. “Wait, you’re okay with this?”

The man nodded vigorously. “Of course! You see, there’s plenty of studies out there that could use a few lab rats, and I’m well aware that not everyone likes to have their teeth cleaned.”

Kyle felt attacked. At the same time, if he really was in the right place, at least he’d never need to see the dentist again.

“So, just the two of us?” Kyle offered, hoping to speed the conversation along.

“Oh, hardly. My nurse will be here to assist us. Ashley, if you would?” The man turned towards a door behind him, and quite possibly the most gorgeous woman Kyle had ever seen stepped from behind it.

She was a brunette, with just enough freckles to catch the eye and hold it. Her top accented a soft midriff, the kind that he could spend hours holding close to him under a sunset-

“You’re staring,” she giggled. “Don’t worry, that’s natural. I’m sure Doctor Klein here explained everything about the procedure?”

“Um. Sure,” Kyle swallowed. This first date was off to an awful start.

“He hadn’t even asked my name!” Doctor Klein smiled that too-wide grin once more, bouncing on his heels and acting like the world’s worst third wheel.

“That’s fine,” Ashley reached out a hand to Kyle. It was like being touched by a goddess. His mouth was dry, his knees were weak, and he followed after her in a trance.

The sway of her hips led him to a medical table. Her breasts pressed against him as she unbuttoned his shirt and pants. Her tanned skin caught the light of a complicated ray emitter perfectly.

Hold on, some of those things weren’t quite right.

Kyle blinked, and looked down to find that he was dressed in nothing but a loose blue hospital blanket.

“And here we go!” Doctor Klein chirped, standing at Kyle’s left.

“Open wide,” Ashley purred from his right.

“Ahh?” Kyle opened his mouth, deciding to focus on the angel to his right instead. It left him totally unprepared for the doctor shoving a latex-clad hand into his mouth, as well as a silvered mirror. “AWLPH!”

Ashley laughed, stroking a hand through Kyle’s hair. “Really, you made this too easy.”

Kyle felt a tugging against his front teeth, and he quickly sent a sharp glare towards ‘Doctor’ Klein. To his surprise, the man’s hands were now both preoccupied plying with Kyle’s gums. The mirror that was once in his hand now rested on a table, showing Kyle a reflection of Klein, Kyle, and… That was it.

He looked to his right, seeing Ashley’s smile widen. He looked to his left, seeing a distinct absence of Ashley in the mirror. He looked to his right, and the smile widened further.

“Aghm,” Kyle lifted a hand, turning his attention instead towards the dentist. “Whgath gowin awn?”

“Hm? Oh, Ashley explained it all in detail earlier,” Klein hummed, poking and prodding at Kyle’s aching teeth now.

“I’d imagine Kyle was a bit distracted at the time. Glamours tend to affect men in such a predictable way,” Ashley play-pouted, hopping atop the chair and straddling Kyle.

Naturally, Kyle was conflicted. On the one hand, today was turning into a rather terrifying experience that preyed on the worst of his distates. On the other, Ashley was rolling her hips against him, humming ever so gently.

Klein decided the matter for Kyle, reaching above the man’s head and pulling a larger mirror down, so that Kyle could see his own reflection. In an instant, Kyle realized that he was right to suspect that something was wrong with his teeth.

His incisors had grown, giving him almost a buck-toothed appearance. They had pushed the rest of his teeth around, giving his jaw a rather unkempt, feral aspect.

“Whgha?” Kyle yelped, trying to rise. Ashley pressed a hand as soft as a feather against him, driving him back with all the force of a bulldozer.

“I don’t think he understood. May I?” Klein asked Ashley, and received a nod in response. “Yippee! Okay, Kyle! You see, Ashley here happens to be a vampire. And, you know how it goes, she’s turning you into an animal.”

Kyle struggled to keep up with what was happening. He was going to be an animal? Ashley was a vampire? A grown-ass man had just used the word yipee?

“I don’t think he gets it.” Ashley cooed, laughing with a delicate tone that drew soft white hairs from Kyle’s skin.

“What’s not to get? I explained everything perfectly.”

Kyle watched his reflection as his overbite was joined by an underbite, and fur covered his body. There was a chance that it wasn’t a mirror, and was instead some TV for a prank show. Kyle pretended that was the case, valiantly denying the truth.

“Nope, he definitely doesn’t get it,” Ashley laughed,  stroking Kyle’s cheek. She leaned in closer to him, so that her face took up half his vision. It was hard to see her through one eye, and a reflection utterly devoid of her through the other.

“Aghmnal,” Kyle expressed his confusion as best he could, shuddering as Ashley leaned in close, rubbing her nose against his.

“You see, sweet boy, vampires don’t feed on people’s blood. We feed on people’s humanity. And we don’t need to bite anyone… Though that’s not to say it doesn’t help.”

Each nuzzle made Kyle’s face twitch, and he whimpered as his nose and mouth slowly slid further and further from his eyes. Soon a muzzle occupied his vision too, with a pink and frantically twitching nose at its tip.

“And I’m here because vampires have revolutionized dental science! Imagine the possibilities that could be discovered from seeing a human mouth become something else altogether!” Klein shattered the mood by prodding at Kyle’s mouth again, poking and prodding.

Kyle whimpered, nose still twitching. Ashley stroked and tugged at his ears, and he saw them widening in his reflection, obeying every kiss of her invisible hands.

With a pointed snout, this ridiculous overbite, and big round ears, he almost looked like a mouse.

“Oh! He gets it! Well, no sense in waiting any longer, then,” Ashley giggled, molding Kyle like putty in her hands. She opened her mouth wide, revealing a pair of sharpened canines, then sank them down into Kyle’s neck.

Immediately, all panic was overwritten by pleasure. Kyle’s eyes rolled in his head as an orgasmic sensation tickled his nerves, converting every sensation to pleasure.

“Aw, but they’re so much harder to look at when they’re small!” Klein called, somewhere off in a distant land where he couldn’t possibly bother Kyle.

The only thing the changing man could think of was the goddess atop him, and the delightful warmth of her touch. His hips bucked as she filled his vision, and a high-pitched whine slipped from his mouth.

“Ssh, it’s okay.” Her voice was louder, booming like a giant’s. Her body felt like it was growing bigger around him, enveloping him in warmth and soft pleasure.

A hand as large as his hips stroked his backside, working a small nub from the base of his spine. The second it was large enough to touch, Ashley tugged at it.

It was like pulling on a thread and unraveling a sweater. Kyle’s body shuddered and convulsed as his humanity was pulled away from him in the best way possible.

Electric ecstasy drove another squeak from his mouth as his hands and feet twitched and shook themselves into paws. His arms and legs shortened, becoming stubby and useless. His spine brought his head up, making him look straight ahead like an animal should.

Ashley noticed his difficulty, and cooed. She cupped the back of his head in a too-large hand, pulling it forward enough to see the mirror once more.

All he saw was a rat, a white-furred thing with red beady eyes and yellowish teeth. He hadn’t even noticed the blanket slip away from his diminutive body.

“Almost there,” Ashley cooed. “Doctor, if you would be so kind?”

Kyle’s mind swam with a haze of pleasure as tried to regain his bearings. Ashley’s fingers, each larger than his head, rolled the man-turned-rat onto his belly.

He realized in that moment that he was aroused, moreso than he could remember being in his entire life, and that his manhood was now pulled taut against his belly by a sheath.

“Got it right here!” Klein’s voice grated on Kyle’s nerves, but even that didn’t keep him from pumping his hips against the chair.

“Ooh, someone’s already starting. Better hurry up, then. I don’t want to miss any of this,” Ashley hummed, her voicee miles above Kyle’s body.

The mirror lowered itself before Kyle, and at the same time Ashley scooped him up in her hands. From his perspective, it looked like his reflection was floating, that invisible fingers were stroking the soft fur on his belly.

Then a small latex mouse floated beneath him, and Kyle’s body was lowered atop it.

His nose twitched frantically as he realized this faux mouse was bathed in the scent of a female. Even if it wasn’t, he still might have succumbed to his lust from how pleasurable the change was.

There wasn’t a moment’s hesitation. Kyle’s paws scrabbled at the thing’s sides, and he began to pump his hips insistently, basking in renewed pleasure.

“That right, my pet. Hump, hump that humanity away!” Ashley cackled.

“I don’t think you explained that part to him,” Klein unhelpfully added.

“E-EEK! IIK IIEEE!” Kyle squealed, unable to stop his hips despite a sudden surge of panic. What did she mean by that? Why was his little heart beating so fast? Why did humping this mouse toy feel so good?

“Oh, right!” Ashley gasped. “How silly of me. You see, Kyle, it’s all part of the process. If you’re able to hold back on your impulses and not find release… Well, you’ll be able to change back! Isn’t that wonderful?”

As she spoke, she drew closer and closer behind him. Kyle could tell from the volume of her voice, and the kiss of her breath against the back of his furry neck. As ever, the mirror proved singularly unhelpful in showing him where she was. All he could see in it was a little white mouse literally humping his life away.

“EEP!” He squeaked miserably, trying to slow down, trying to think of football, calculus, and football calculus. The derivative of an in-line receiver squared by an offensive guard was…

“Don’t fight it, pet,” Ashley breathed from behind him, stroking his ears, kissing his chubby little back.

“EEK!” Kyle’s eyes glazed. Runningback… To the… Quarterintegral… Think… Hard…

He played a shrunken tongue along his oversized teeth, feeling how unkempt and big they were. They tasted awful, but something about that only turned him on more. He humped faster and harder, making the little latex mouse squeak beneath him too.

“He’s so close!” Ashley giggled victoriously. “And I know just what he needs.”

She lowered her pinkies to Kyle’s cheeks, stroking them and reminding him just how long his face was. The pets trailed from his ears, down along his fuzzy plump cheeks, to his whiskers, and ended at his twitchy nose.

It was the greatest feeling of Kyle’s life. His jaw went slack, and he squealed as he came, spurting into the latex mouse until his balls were as empty as his head.

“That’s better. Now that I’ve had my fun, you can do with him as you will,” Ashley stroked the rat’s quivering, spent body with two of her fingers.

“Of course!” Klein bobbed his head eagerly. “I think this little lab rat is going to be used to study the effects of…” He started to prattle on, in his element.

The rat squeaked and panted raggedly, too dimwitted to care about what the man was saying, much less the irony that he really wouldn’t be seeing a dentist again.
