Losing A Thermometer

Trojan wasn't like other dogs, it wasn't just the Doberman's superior intelligence, his awareness of the world around him and the 'role' he was supposed to play, he also had the ability to alter the size of whatever, or whoever he pleased, just by concentrating.

He revelled in using that ability to make 'stereotypical dog activities' more enjoyable, cars were easier to chase when they were a more manageable size and postmen made better snacks when they were actually snack-size. He'd been through many 'owners' by now, using them to keep up the ruse of being a 'normal' dog until he grew bored and shrunk them down, using them as toys before disposing of them and moving on.

His current patsy was different, there was something about this Caracal that Trojan couldn't put his paw on, the fact that he was a cat meant little, Trojan was above the canine-feline rivalry. No, this 'Roon' character was different to everyone else, in the back of his mind Trojan suspected that the Caracal not only knew of his abilities but shared them. With no evidence of that yet he played it straight and acted as he'd done with the others.

And so it was that he found himself in the waiting room of the local Veterinarian, sitting at his 'owner's' feet observing his surroundings. Ignoring the other animals he instead noted the exits and staff movements, he didn't necessarily plan on doing anything but it helped to be prepared for a quick escape if caught in the act. Vet visits helped him keep healthy, he knew that and usually refrained from having 'fun'.

Roon was absent-mindedly flipping through a magazine when the vet called him up. After a few moments with no reaction, Trojan realised his 'owner' was showing no interest and decided to walk over by himself. The Caracal never bothered with a leash and Trojan preferred it that way.

"Well, ok then. Trojan is it? Come on through boy", the Rabbit vet said, looking over towards Roon, who merely glanced at the two before opening up another magazine.

Trojan walked through the door the Rabbit held open then jumped straight up onto the examination table and stood there posing, he quite liked showing off. What's the point of being lean and muscly if you don't show it off? He couldn't help but smirk a little as the vet paused for a moment and stared, before walking over.

"Now, you're just in for a check-up right Trojan?" the Rabbit asked before walking to the bench along the wall and opening a drawer. Trojan paid little mind while the vet rummaged around until the Rabbit spoke aloud to himself.

"Whoops won't be needing a rectal thermometer, only need to use those as a last resort these days"

Trojan's ears perked and he snapped his head towards the small glass thermometer as the vet put it down on the bench-top, before pulling an electronic ear thermometer out of the draw.

"Now that could be promising..." Trojan thought to himself, thinking of his favourite way to play with his shrunken toys. "But I don't know if I should, I try to keep vets off-limits and besides, it's a bit late to swing the situation in my favour" he liked to play circumstances to their fullest, mind games always made the physical fun that much better.

Just as the vet returned to the table, a second door at the back of the room opened and another vet, this one a Fox, came into the room.

"Dr Grath, that dog you did surgery on yesterday, the Mastiff, he's managed to tear open his stitches! You need to come and close the wound again" the Fox said, slightly panicking.

"Damn! Alright Brenda and I can handle it, I'll need you to do this dog's check-up for me." The Rabbit said putting the thermometer on the table and heading for the door.

"This dog?" the Fox asked looking nervously at Trojan, who grinned mischievously.

"Yes that dog, look you're not far enough through your training to handle the situation out back but you're more than capable of this" the Rabbit said indicating Trojan as he disappeared through the doorway.

Trojan's luck improved as the Fox glanced at him again before chasing the Rabbit through the door, leaving him alone.

"A trainee vet? What luck, looks like I'll get to have some fun after all" Trojan thought, feeling his sheath start to swell. "No, no not yet" he willed himself to calm down, "Can't get excited now or he'll be suspicious".

Firstly Trojan looked down at the electronic thermometer on the table, which he quickly shrunk down to miniscule size before stamping it into dust. Next was a box of disposable gloves on the bench, shrinking them to an unwearable size while leaving the box untouched.

"That should keep things more 'hands-on' and personal, it's less fun when there's a layer of plastic in the way" he thought slyly.

Just then the door opened again and the Fox reluctantly walked back in.

"Alright let's get this over with" the Fox hesitated for a second when he saw the smug, almost predatory look on Trojan's face. "Uuuh.. Trojan is it? I'll be looking you over okay?"

The Fox briefly looked at the table before heading to the bench and looking through the drawers, "Thermometer, thermometer..." he then left the room again.

Returning shortly after the Fox stared at Trojan, "Use a rectal thermometer on that dog? The doc must be crazy, the teeth may be at the other end but he's not going to like this" he said to himself.

The Fox seemed determined though, as he walked over and picked up the glass thermometer and went to put on some gloves, "You've got to be kidding me! How did these all shrink?" he said upon discovering that all of the gloves were too small. The fox checked in one of the cupboards and growled in frustration at apparently not finding another box.

"Fine, I'll do it without the gloves, only the thermometer needs to touch him anyway, it's long enough that I can keep my fingers clear" The fox tried to convince himself.

As the Fox approached, Trojan shifted on his rear legs, his stubby tail twitching in anticipation, "Come to papa" he thought, feeling his sheath stirring again.

"Ok this might be a little uncomfortable and probably a bit cold too, just don't bite me ok?" The trainee said nervously, reaching up and gingerly gripping Trojan's tail stub in his fingers, the shiny black ring of flesh clenched as the Fox looked at it, appearing almost as a target, surrounded by the copper-brown fur of the Doberman's underside.

Trojan waited patiently as the Fox hesitated again, he looked back over his shoulder, trying to look uninterested but unable to hide the smugness as he thought of what was going to happen, enjoying the superiority he had over the Fox even before the fun had begun.

With a twinge of coldness and a shiver of pleasure running up the Doberman's body the tip of the thermometer was inserted. Trojan barely contained a whimper but was unable to prevent the end of his penis from sliding out of his sheath, as the thermometer was fed into him.

The Fox was surprised at how easily the Doberman was allowing the thermometer's entry and was shocked when he noticed the dog's growing arousal.

"Well so much for being uncomfortable, seems as though you don't mind this at all boy" the trainee said, letting go of the thermometer as it reached the desired depth. "One last look for some gloves..." he said moving to another cupboard.

"Showtime" Trojan though happily as he started clenching his anal muscles, pulling the thermometer in until just the tip was poking from under his stubby tail. The Doberman watched intently as the Fox looked back over at him and saw the predicament.

"No! Stay thermometer, stay" the Fox yelled, running over and reaching up with his fingers to grab it. With a powerful clench, Trojan pulled the thermometer completely inside himself just before the Fox could get it.

"Bugger! That's... I need..." the Fox sighed, "I need to get that back now don't I?" he asked himself, glancing at Trojan and noticing the weird look the Doberman was giving him.

"If I didn't know better I'd say you did that on purpose. But I suppose a dog doesn't understand things like this" the trainee said, eying the smug and somewhat excited look on the dog's face.

"Okay... Looks like I'm going in" the Fox said, resigning himself to what was coming.

"You're more right than you know" Trojan thought grinning. He couldn't help but lean back and stick his hind-quarters out towards the trainee vet, unable to hide his eagerness.

The Fox thought it a little strange when the Doberman practically stuck it's butt in his face but passed it off as a reaction to the thermometer being inside. Reaching up, he accidently brushed the dog's balls and jerked his hand back as Trojan jumped on the spot. After getting no further reaction out of the Doberman, he gripped the tail stub again and looked at the quivering, clenching anus in front of him.

Trojan watched, standing tense, still as a statue, waiting for the fun to begin. With a sigh the Fox raised his right hand stuck out his finger and slid it into him.

"Yes! Playtime begins" Trojan thought as the newly inserted finger began probing about, seeking the thermometer. The feeling was of course, great, as the Fox slid in a second finger to try to grip the thermometer to pull it out.

Clenching down hard to hold the Fox's fingers in place, Trojan stared at the trainee vet and began concentrating, his erection reaching full size and his knot starting to swell as the Fox dwindled in size before him.

The Fox felt something happening but he couldn't work out what. His fingers were stuck in the grip of the dog's black ring and he couldn't budge them. Then he felt his uniform start to loosen around him, no sooner had his pants fallen to his ankles than he felt his feet leave the ground and his shoes behind.

Thing proceeded quickly after that. Clenching and pulling the shrinking trainee up to his elbow, Trojan watched lustfully as the tiny Fox disappeared into his coat before popping out through the sleeve as it fell to the floor. The now five inch Fox was at the perfect size, desperately struggling against his ring, tickling the sensitive flesh as his legs kicked about.

As he felt his arm get pulled into the dog's butt, the trainee vet's world went completely white for a few seconds before the end of his coat's sleeve flew past and vanished below the table. This couldn't be happening, there was no way he could possibly be pressed against a giant feral dog's ass hole with half his arm stuck inside.

There he was though, the heat of the Doberman's rear end against him, the squeezing around his arm, the huge dog balls hanging below his dangling legs, this was real. That was when the Fox started panicking, kicking his legs about, pulling at his arm, trying to get free. Then with a powerful clench from the ring before him, his world became dark and humid.

"Excellent!" Trojan though gleefully, enjoying the tiny limbs beating about his backside, "This feeling never gets old". He stood for a moment, feeling the tiny Fox dangling and flailing beneath his tail, somewhat wishing there was a mirror nearby so he could watch.

"Oh well, better get a move on, don't want to be caught" the Doberman then proceeded to clench his hole, pulling the Fox's head in, then clenching again to pull him in up to his waist.

The Fox started kicking as hard as he could as his other arm was pinned to his side and he felt the hot fleshy ring reach his waist. Part of him knew that struggling would get him nowhere but his instinct to escape was overriding everything else. The throbbing flesh tube slid against him, rolling over his whole body as two more muscle clenches pulled him completely inside the dog, he felt the ring clamp down behind his feet and began thrashing about desperately.

A couple of clenches later and Trojan's new Fox toy was sealed inside and squirming beautifully. His cock shooting a few strands of pre as his knot reached full size and began throbbing. Leaning his head down and cocking a leg, Trojan licked the tip of his cock a few times before taking it into his muzzle and working his tongue around it.

A few involuntary clenches pulled the Fox deeper inside, past the thermometer, to beat against the dog's prostate as the Doberman pumped his tongue along the length of his shaft. Just as he reached orgasm, Trojan clamped his teeth gently behind his knot and fired rope after rope of hot cum down his own throat, making sure to swallow everything.

Trojan stood wobbling slightly, utterly satisfied and enjoyed the struggling Fox deep inside, still kicking strong. He then leant down and licked up any pre that was on the table, so as not to leave any evidence. Once that was done the Doberman squatted down and began pushing out the thermometer, feeling its length sliding out before it clattered onto the table. He of course left the still struggling Fox inside, just within the 'exit' ring.

Trojan had just finished shrinking the trainee's uniform into nothingness when the Rabbit vet came through the door, pausing when he saw Trojan.

"Well you certainly are a patient dog Trojan. Where's that Fox got to?" the vet asked before spotting the thermometer behind the Doberman. "I see, well it's not the first time he's done a runner when I needed him to do something outside his comfort zone" the Rabbit grumbled, "Last time he disappeared, I'd asked him to assist me in de-sexing a cat. These are the sorts of things a vet needs to do, I don't think he's cut out for it".

"You know what? I think we should reschedule your check-up boy, you seem in good health and I'm running behind now, with animals out there with actual problems that need to be seen to" the Rabbit said, clearly frustrated. "Hop down Trojan and head back out to your owner" the vet said opening the door back to the waiting area.

Trojan glanced at the rectal thermometer and smirked before jumping down to the floor, a shiver of pleasure running through him as the Fox within was jolted about. The Doberman trotted through the door, his hind legs slightly askew and went across to Roon. Sitting down daintily, so as not to cause another shock to the system, he looked up at Roon and was confused to find the Caracal smirking down at him. Almost as if he knew...

"Mr Roon, I'm afraid we've fallen a bit behind, you'll need to make another appointment for Trojan's check-up" the vet stated "Brenda will be back out at reception in just a moment" the Rabbit then called the next patient before walking them into the exam room and closing the door.

Roon stood up and headed out the exit, with the Doberman following quizzically, "Looks like we'll need to find you a new vet Trojan" the Caracal said, still smirking. Trojan stopped in his tracks and stared after his 'owner', who continued walking down the street.

The Caracal looked back at him, grinned and said "Come on boy, let's go home".

With the tiny Fox still kicking pleasantly within his bowels, the Doberman caught up with Roon and trotted along beside him. "This one's going to be interesting... " Trojan thought to himself, glancing at the Caracal.

The End?
