“How's Missy been acting up?" asked Emma to Prudence.

Pru hugged her lily green lizard pet to her chest. The creature looked around the Sapient Biology Lab warily, and tightened the grip of her claws around her owner's blouse. The lab was a softly lit, humid and warm room with ranks of classroom desks in the center and an astonishing variety of cages and glass terrariums arranged on sturdy shelving around the sides. The place smelled of animals, mostly of the reptilian kind.

“She's been very restless, squeaking, picking up things and carrying them around the house. Nudging me when I'm on the couch, and laying on me when I'm asleep."

The lab supervisor nodded. “Some reptiles are sociable and need others around them. How's she been doing for that?"

“I give her lots of affection," said Pru, ruffling the creature's loose neck skin. Missy squeaked and nuzzled her chest. “But I work in the day time and I recently broke up with my boyfriend, who was her only other company. Huh, that might be it."

“Yeah," said Emma. “We can help with that."

The lab supervisor motioned to the cages and tanks. They mostly looked empty, until a pile of stones or part of a log shifted and turned out to be a scaly, lurking thing. Pru saw a six legged lizard nudge open the top of their cage, crawl out with a lump of meat, and slip into another tank, where another creature stirred.

“Errr, one's just escaped," said Pru. Emma smiled.

“This lab is for sapient animals, and alt-sapients like Missy," she said, “Sapients are about as smart as us. Alts are not quite human intellect, but not far off, or they just think so differently to us that we can't really relate their minds to ours. But as they're clever in one form or another, we find it's best not to lock them in. They are… guests? Not inmates."

“Oh," said Pru. Missy was a rescue animal of unknown species, and didn't show her intelligence until months after Pru adopted her, and found her having a bath in the sink. On finding out she wasn't an ordinary animal the vet closed their account and forwarded them to Brin University's sapience lab. And so, here she was, holding a lovable but increasingly troublesome lizard and hoping the little creature wasn't going to cost her a fortune in bills. However, Professor Emma Dietrich was so far the first person to actually know things about Missy, to Pru's great relief.

“We can house her while you're at work, like a reptile crèche," continued Emma. “She can freely mix with the others. It's free of charge, as long as you - and Missy - doesn't mind us running experiments on her."

Pru noticed Missy's tail flinch and curl around her tighter. Her eyes widened.

Did she understand that? thought the little beast's owner. She's smart, but surely not understand English smart…

“Experiments like…"

“Nothing nasty!" said Emma quickly. “Mostly taking samples and doing mental challenges. From what you say, she's really clever."

“Well, free sounds good," said Pru.

“Also, if she's rubbing on you, she's probably in heat too."

Pru blushed and stared disapprovingly at her lizard, though with a slight cheeky smile. “Missy! I'm not that kind of girl!"

Missy looked up at her and blinked.

“It is what it is," said Emma diplomatically, “but if Missy wants _that_ kind of company, there's lots of it. We'll let nature take its course."

Pru blushed and giggled like a schoolgirl.

Emma walked towards to the door. “I have a class here, so I'll be back shortly. Pop her in a tank if you want to let us look after her. You can stay for a while to see how things go."

The supervisor closed the door after her, leaving Pru and Missy alone… or actually, not alone at all. The sole human looked warily around at the beady eyes and scaly heads staring at her from the cages. The lizard in her grasp clutched her chest tighter.

Pru made her mind up and walked towards the wall of tanks. She smiled dotingly at her pet. “That one over there looks about right."

As the woman approached the wall, Missy started to struggle.

Pru snuggled her pet, covering the lizard with both arms. “Hey, don't worry, it's like your first day at school. You'll make friends quickly."

Missy climbed around her arms. She was big for a lizard, about the size of a five year-old child, and put up quite a struggle.

<-ot going. Not doing.>

Pru looked around. “Hello?" she asked.

<Not want. You do it.>

Missy returned to grasping Pru's chest. The woman tried to hunt for the source of the voice. But her feet didn't obey her. She stood in place, her body relaxed except for her arms still securely holding Missy.

Aghhh, what the hell?

Missy felt heavy at her waist. She was bigger, but so was the whole room! Pru tried to call for help but her voice box didn't engage and all she managed was a breathy hiss. Her tongue flopped out of her mouth and dangled past her neck to her chest. She was still shrinking, and Missy was still growing. At just the point the lizard was too heavy for the woman's withering arms to hold, the beast's feet touched the ground and she took her owner's weight instead.

Pru's eyes widened in horror as her lizard pet's scaly body smoothed into soft human flesh at the same time as her own body became the soft green that Missy used to be. Pru's dress slid off her shrinking and reshaping legs, followed by her panties, which were being pushed off by her new lizard tail.

You're doing this! thought Pru as she saw the expression of fear and excitement in the increasingly human creature holding her now mostly reptilian body.

<Ohhhh it's working! Aghhh so many thoughts!> came the voice, which Pru realised sounded exactly like how her own internal voice sounded.

The once-human's clawed feet and tail dangled limply in Missy's grasp. The once-lizard used a shaking hand to tug Pru's blouse and bra away, leaving her naked.

By the time the new lizard's muscles started obeying her, she was a weakling, locked tight in the embrace of a being that now looked exactly like she once had.

“Eeeee-eee!" squeaked Pru.

<This is… lab. Other human is Emma Dietrich. Owner is Prudence Thorpe. Owner is frightened. Feel guilty!>

Then turn me back! thought Pru, as she scrabbled her blunt claws against the huge human's soft, naked skin.

<Ow! I can hear your thoughts! Can you hear mine? Of course you can!>

Missy's human form stumbled and leaned on the shelving. She raised a floppy hand and nudged open the terrarium her owner had picked out for her, pushed and hauled Pru into it and let go of her. Missy's owner landed on a pebbly floor and she felt the warmth and hardness of the stones through her bare stomach, chest, thighs and the underside of her tail.

Pru stared through the glass at her enormous, now human pet. Missy grasped her head with both hands. The lizard could feel Missy's presence inside her own mind. The pet was probing Pru's own brain, plucking thoughts and memories from it. In return, the former human peered into Missy's own mind and felt an overwhelming rush of new experiences. In seconds she learned how to be a reptile, how to live as the creature she now was.

No, I don't want this! Turn me back Missy! Your mommy is scared!

<Your flat is an absolute mess!> came Missy's now angry thoughts. The once-lizard reached down and picked up Pru's panties. Pru felt a curious prickle in her brain as her pet accessed the bit that knew how humans wear clothes, and Missy slid in to the undergarments with a self-satisfied smile.

My flat?

<Is a tip. I live there too. You have three… pizza boxes? Pizza boxes on the floor, they've been there for a… week!>

Pru gaped as she watched the creature put on her clothes and become exactly the woman she had seen in the mirror before she had left the house.

<Robert left because you had let everything go. He tickled my throat! He gave me the right kind of food scraps! He was nice!>

I… okay?

<You stay on your… mobile and don't play with me enough.>

I thought I gave you enough attention?

Missy stared angrily through the glass and popped the tank's cover back on.

<Promise to tidy the flat, uninstall that farming game and I'll turn you back.>

Pru shrank back from the huge head with her face. Then stood up on her hind legs defiantly. Her head bumped the tank's cover.

No. I'm not taking orders from my _pet_!

Missy sat down grumpily in a chair while her owner crawled onto a log. As they sulked, Emma returned to the room with a laptop and two students. Missy tilted her head up on her shorter human neck, and put on a fixed, nervous smile. The supervisor smiled and nodded back, clearly none the wiser, and prepared her class while more people filed in and sat down.

A light grey snake with soft, white feathered wings slipped out of his cage and stared unblinkingly through the glass at Pru. The lizard backed away and looked about nervously. To her he was a giant, rippling cable of flexing muscle, and his mass circled half way round her whole tank. Pru spied a catch on the ceiling of her enclosure. She reached up and quickly pulled it into place.

The tank locks on the inside! I guess if we're guests… I mean they're guests…

<I wouldn't let him hurt you,> thought Missy to Pru defensively, casting a glance at her. <You're my owner.>

You turned me into a lizard!

<I'm a lizard all the time,> she replied primly. <Do you give in?>

Pru turned her head away and stared elsewhere. Which happened to be the tank next to her own. A very strange creature lay within, with the head of a cockerel, colourful bat wings and the lower portions of a lizard not unlike Pru. His eyes were closed, mercifully, because Pru realised he was a basilisk. He was curled intimately around a stone statue of some sort of winged, club-tailed humanoid. The statue shuddered and tightened its grip on the beast, and Pru realised it was another animal. A miniature gargoyle?

The basilisk adjusted himself a little. Pru realised that they were mating. His scaly groin pressed firmly against the craggy hips of the gargoyle, then pulled back to let their voyeur see his wet, thick animal penis, before he pushed himself back into her in a leisurely fashion.

Ewww… I can smell their sex too.

The lizard turned back towards Missy. Her pet was staring at Emma as she taught her biology lesson.

<…is an overhead projector… powered by… electricity…> came Missy's thoughts, rambling, vague and distant now she was thinking to herself rather that at Pru. She soaked up everything her senses took in, excited to comprehend everything around her for the first time.

Missy's owner found herself looking back at the mating beasts next to her. Their sex was casual and relaxed, as if they had been doing it for hours. And maybe they had? They looked comfortable and content. A trickle of goo ran down the gargoyle's leg. Pru's nostrils twitched as she breathed in the creature's musk.

Gross, thought Pru, not quite convincingly.

The winged snake's head crept into view. He was staring right at her, while his coils lounged around the tank. The reptile backed away uneasily until her rump pressed against the tank's glass wall.

The snake raised his tail and pressed it against the other side of the glass pane. Pru watched his scutes shift and a couple of purple, worm-like growths peek free.

Euhhh… thought the lizard. Right next to my ass…

Pru didn't move her scaly butt, even when the serpent's tail slipped over a little and his firming, thickening penises ground against the grass right at her crotch.

I'll just… wouldn't hurt to…

She wiggled her rear end, lifted her tail and pressed her nethers against the glass. The snake's groin heat transferred through the pane and warmed the transformed girl's intimates.

<Prudence?>

Pru flinched and looked into the Missy's huge, concerned human face.

<What are you->

Nothing! retorted Pru.

<Don't make him excited! That's mean!>

Pru tugged her butt away. She left a wet trail on the glass. The snake looked at her curiously.

Why did I do that?

The lizard knew why. Her loins were on fire. Every time she smelled the mixture of animal mating musks in the air she felt the urge to add her own to it. She tried to be disgusted at herself, and failed.

Uhhh, how did you turn me into, err, you? asked Pru at Missy, trying to take her mind off the thoughts of warm, cuddling scaly bodies against her own.

<Uhhh… I…> Missy looked ashamed. <When you were asleep, I found I could hear your thoughts, learn little things about the world from your mind. And I could… change you. Just a tiny bit.>

I… sometimes I'd wake up and be sure something wasn't quite right…

<There were a few close calls,> admitted Missy. <I didn't mean to harm you, I just… loved the bond with you. So I strengthened it, bit by bit each night…>

Hhhh… mmmmhhhh…

Pru tried to quieten her lustful thought so her pet wouldn't hear them. Missy continued to talk, but she stared off into the distance, too embarrassed to look upon her owner as she described how she climbed on the Pru's bed and manipulated her form.

Missy's owner, very distracted by the new sensations in her body, experimentally lifted her tail and waved it around. Brought its tip up to the catch on the tank's ceiling. Unlocked it.

Oops, just an accident, she thought quietly.

<-worry about you. I wanted to know why you were acting so sad, so I looked in your head for the reason.>

Okay, that's a bit… personal.

<I didn't know what personal meant. I'm sorry.>

Pru placed a claw on the glass. Missy blushed and rubbed her fingers against the other side of it.

Then the lizard heard the lid of her tank lift. She glanced away to see the winged serpent's tail slipping in. Her heart fluttered and she gripped the stony ground with her claws.

<-think so many things. You're so smart, you have so many thoughts buzzing around.>

Mmmh…

The snake's tail pressed against Pru's own and wound around it. Inch by inch he carouselled up her body, his powerful muscles flexing against her leathery hide.

His twin penises slithered smoothly into place underneath Pru, nestled against her scaly slit. She shivered in anticipation.

I shouldn't be… mmmhhh…

<-to help you, owner. What can I->

Ohgod, they're both in me!

Missy's owner felt the warm, slick lengths slipping firmly into her opening. They nestled deep, then the reptile slicked them out a little and plunged back in.

Aaaah, ohmygod, ffffffffff…

Missy looked into the tank and her eyes widened as she saw her owner rutting with the snake. Half the serpent was inside the tank and the rest was squirming in to coil about his mate.

<Prudence! What… how could you…>

Pru squirmed and flexed in the snake's powerful grasp. His whole body slid into the tank and he eagerly wrapped up the once-human all the more. The lizard licked the snake's throat as he wound his neck about hers.

<Prudence!>

Missy could feel her owner's pleasure as clouds in her mind. She stood paralysed before the mating couple, unsure how to act, or how to feel.

Pru's eyes half closed and she rubbed her claws along the winged serpent's rippling length as he took her, his thrusts like spasms that shook them both.

Then the lizard felt his movements change, his manhoods remain deeply anchored in her. He squeezed her tighter still.

Pru squealed as the snake's movements stilled, except for a heavy trembling about his tail where his manhoods protruded and speared his mate. Suddenly, his cocks jumped inside her and thick, warm splashes of semen gushed free into her body

Nhhhh, hhhhrrrrr… mmmmmm…

Emma looked away from the screen as Pru's squeaks issued across the room.

“Hah, I see our new guest has had some fun. That was fast!"

Pru ground her hips against the snake's body. She was seconds from delicious climax, but he was already growing limp.

So close! Just a bit more!

Then the girl felt her human shame grow as she realised what she had done.

Ewww, I didn't really do that, did I?

<Owner, you just…>

Of course I did…

She could feel the snake's spunk in her, and his softening lengths. His body weighed her down, and his delectable, inhuman musk emanated from her nethers.

The snake uncoiled about her, contentedly going limp about her body like discarded rope. His hemipenes slicked out and his cum dripped from Pru's inflamed, sensitive scaly slit. She looked down at herself and shuddered with shame.

The lid flipped up and a pair of hands descended.

“Eeee!" Squealed Pru as Emma lifted her out with some effort.

“My, such a thirsty girl!" she said, to chuckles from her students. She hugged the creature to her chest, careful to keep Pru's wet, gooey lower regions from staining her lab coat.

No, it's not like that! I… don't… uhhh…

Emma put the lizard down on a central table and the students clustered around her.

“So as you can see, the Migration's close proximity influences sapients and alts, making them interested in mating outside their species. It usually also makes heat last much longer and in some species makes it last until they move far enough away."

Emma stood Pru up on her hind legs, resting her forelegs on a metal stand. Her reptilian slit was on full display, and edged with snake semen. Pru, mortified, tried to hide her head, but she was surrounded by students, all looking at her. She considered curling into a ball or running away, but it felt… wrong to disobey the giant human.

Missy stared from a little further away, unsure what to do, her new humanlike sensibilities disapproving greatly at her owner's shameless conduct.

Pru, despite her humiliation, let Emma manipulate her. She was still feeling frisky from the mating and the human's confident touch was pleasant on her naked, scaly body.

“We still don't know her species," said Emma, “but she's docile and easy to handle. She resembles a water monitor in size and looks, but she has more mobile limbs and a rather expressive face."

Emma rubbed her hand down the girl's spine. Pru closed her eyes and enjoyed the warm touch go from her back to her rump and along her whole tail to the tip. The sensation was calming and the creature opened her mouth and let her tongue lol.

Now, let's take a look inside."

Emma took a slim black rod and brushed its head against Pru's slit. The once human woke from her comfy daze and squirmed, but another confident stroke along her spine calmed her. Pleased at the lizard's good behaviour, the supervisor gently inserted the rod into her. Pru felt its hard body creep within and explore her semen-tinged passage. She felt uncomfortable and embarrassed at the close scrutiny, but oddly titillated at the disgraceful treatment, too.

Hhhnnnhhh… ooop. That's… very deep…

Emma tapped a key on her laptop and the overhead projector showed a huge view of a wet, pink passage - Pru's internals. The reptile hung her head low but kept an eye on the screen, fascinated but humiliated. Every time she moved her hips or clenched her groin the passage flexed and jiggled on the screen.

The probe pressed against internal nubs that made Pru squirm. Emma chuckled and let the creature wrestle against her and the bar she had her forelegs against. The lizard couldn't help but start to grind against the rod, causing it to slip deeper still and making her passage close in and open around the probe's camera.

Emma manipulated the probe and the rod curled slightly. She pushed it fully into a small chasm, with little bumps and oval openings. Whitish goo covered the space and washed over the camera.

“Ahh, I thought so. Like some reptiles, Missy's reproductive system stores semen in the oviduct until conditions are right for her to be fertilised. I doubt that'll happen with coatl ejaculate, but who knows!“

Pru shuddered as she was reminded of the snake spunk inside her. She wondered how long her body would hold on to it. She thought about growing pregnant with a winged serpent's slithering babies - either as a lizard or a human.

Emma, noticing Pru grinding against the probe, gently bobbed it within her.

Ohhh, hhhhahhhh… you're gonna make me… ahhh… mmmmeeeerrrrr…

Pru shivered and climaxed around the probe, weeping ooze from her slit onto the table.

The students murmured and chuckled amongst themselves while Emma let the lizard rub the probe against her sensitive, flexing passage and ride out her orgasm. She slipped her hand down Pru's spine, cooing, “such a well behaved little volunteer you are."

Pru's pet internally voiced her confusion and dismay at her owner's submissive happiness. But sh couldn't help it. She beamed inside, loving the encouragement, rewarded with compliments and sexual release, and rubbed her head against the human's chest.

---

That evening, Pru helped Missy clean up her flat. Although her reptilian form made the job much harder, she enjoyed the tasks all the more. She picked up discarded clothes which no longer fit her and dropped them in the linen basket, while the ever fastidious Missy cleaned the bathroom. The once-lizard attacked the mould and streaks with a determination Pru had never seen from any human who wasn't in a spray cleaner commercial. Her pet just loved having human hands, height and range of motion.

They got the place looking better than it had in weeks, then snuggled up together in front of the TV. Pru basked in the warmth of the creature that had stolen her human form.

Pru looked up at her pet. The human was looking at her from time to time, her brow furrowed in concentration. Every time she did this, Pru felt a funny sensation, which went away after a few seconds. Missy caught her owner's slit-pupiled eye and looked away swiftly.

You… you're trying to turn us back, right? thought Pru to Missy.

<I… yes. I'm…having trouble. I made you go through all that at the lab, and I want to reverse what I did. It's my fault, and I can't seem to… make it better...>

Pru pressed the back of her head into her pet's bosom. Missy scritched her throat with her nails, sending a pleasing sensation through the lizard.

Is it based on what you want? thought Pru. She remembered watching a documentary about shapechanging, and what very little information humanity knew about it.

I mean, if you don't want to change, you probably won't? You seem to really like being a human…

Missy looked guiltily at her. “Yes," she said, savouring the words now she had vocal chords to voice them. “But surely I can override that. You didn't want to be a lizard in the lab, and I forced it through anyway. You want to be turned back into a human now, of course, and I don't want to be turned back into a lizard, so same thing, right? As long as one of us wants the change, it should happen?"

Pru shifted her scaly body with embarrassment.

I… enjoyed the lab. It was so… naughty? I know how that sounds! I enjoyed the ride home in the train in the carry cot. I had great fun helping you clean the place. And I'm snuggling against you, as a comfy lizard. Tomorrow I go to work in a job I don't like and do the same stuff I do every evening, and I'll be bored shitless. Unless… I stay as a lizard…

Missy looked down at her pet - her owner! she corrected herself mentally.

“You… don't want to change back either?“

Pru simply put a smile on her snout.

“Well, I…" Missy rubbed her fingers between the reptile's eyes, making Pru squeak with contentment. “At least for the time being, let's deal with things as they are, I guess."
