'You couldn't even break a fox!' The large rhino snorted at his friend as he took another swig of beer

The Doberman scowled in response: 'I could break anyone into a subby little bitch Duncan and you know it.'

'Oh really Guntar? Well how about a little challenge then puppy'

The Doberman leaned back on the bondage bench he was using as a sofa: 'I'm listening'

'Well this lovely dungeon in your basement has been awfully quiet of late, and while picking subs up in clubs and double teaming them all night has been fun I want for something a little more...'

'Go on...'

'So we each go and 'acquire' a sub, bring them back and then have 24 hours to individually break them. Then we have a little test to see which is more obedient after their crash-course and the loser and his sub has to forfeit a punishment to the winner.'

The Doberman smiled wryly: 'Deal. I have just the forfeit In mind, you're going to be sorry you ever thought of this!'

'Not of I can help it!' Replied Duncan 'But it's getting dark out there, let get out and grab us some victi... Willing partners!'

Guntar chuckled as he finished his bottle and joined the rhino in collecting a few supplies from a storage unit before the pair headed upstairs and departed in their separate cars.

--

Duncan parked his mustang up in the quiet loose surface car park. It was at the bottom of a track that led up to a famous view over the city and he knew that students often drunkenly trooped up the hill to take in the skyline and get more drunk.

It seemed like a perfect place to pick up a sub and while the rhino sat low in his seat a prime target jogged across his windscreen. It was a very diminutive grey and white fennec in a tracksuit. He was sweating heavily, having clearly just jogged up the hill and was on his return leg.

As the fox entered the gravel car park the muscle car's engine roared into life and Duncan slammed it into reverse. Cutting the fox off as he reversed in front of him the rhino then proceeded to spin his rear tires up and donut around the confused vulpine and throw up a dust cloud. With his victim suitably intimidated the rhino screeched to a halt and got out - towering over the fox.

'What's your name boy?' he smirked

'K...Kitt' the fennec stammered

Duncan grabbed the smaller fur by the throat and then pushed him up against the side of his car. He then quickly zip-tied the fox's paws behind his back.

'Well Kitt, we are going for a little ride'

'No! HELP! Let go of me!' Kitt shouted as the situation hit him fully and he struggled - with his paws in the plastic ties however he was helpless

Duncan pulled the fox around to the boot and opened the lid. He pushed him up against the lip and held him in place with his considerable body weight as he grabbed a tick black scarf. The heavy wool garment was pulled over the fennec's eyes and tied tightly around his head - blinding him. The rhino then grabbed a dirty sock and a roll of duct-tape and soon the fox was silenced with the horrible sweaty scent of the rhino's feet.

With his victim suitably attired Duncan lifted the quivering fox into the trunk and slammed the lid before firing the engine back up and roaring off.

--

Guntar waited patiently by the front door to the university dorms. A small smile kept across his face as a rowdy group of students approached from the inside - clearly heading on a night out.

'Cheers guys' the Doberman nodded as the last of the group held the door open for him

'No prob dude, PARTY!'

'Yeh!' Guntar replied as he slinked inside and the security door clicked shut behind him

He headed up to the notice board in the lobby where there was a list of students from the dorm who had recently revived accolades - both sporting and academic. He scanned the board for a suitable target and suddenly noticed the school swimming champion - a tubby otter called Mako. Handily the board listed the otters room number, 4/15, so Guntar could go and reward him for his recent success.

Shunning the lift for the stairs the dog quickly ascended to the fourth floor and found room 15. He slipped off his backpack and grabbed a set of handcuffs from inside before pressing his large ear to the door.

He heard nothing but faint snoring from within and trying the door gently he found it unlocked - this was prefect. He opened the door and slipped into the dark room beyond where his canine eyes easily picked out the slumbering otter.

The dog dropped his bag on the floor and poised himself ready to strike...

Guntar suddenly ripped the covers off the otter and jumped onto the bed - he rolled Mako onto his front and pulled his arms behind back - slapping the cuffs on his wrists. The otter started to stir as Guntar grabbed a ballgag from his bag and greeted the waking mustelide by ramming the rubber ball into his muzzle.

'Rise and shine Mako!'

'Hmphhhhmmm!!!' Mako tried to cry out but the gag stopped him and he struggled against the dog's weight as he was pinned to the bed

'Settle down now otter' Guntar said getting off and pulling the final item from his backpack 'You're going to get in this bag and be quiet or I'm going to get mean'

The dog opened up the neck of a leather, laundry style, bag and brought it around the otter feet. As Mako struggled and fought the cuffs the Doberman brought the bag up around him and then forced him down - squeezing his body into the tight musky sack. The dog brought the bag around the otters head and then closed it above him - plunging him into darkness.

A strap fastened around the top of the bag, sealing it shut, and then a heavy padlock secured the strap - locking the otter within. The smell within the bag assaulted the shocked otter's nose - it must have normally been a laundry bag and it reeked of musk.

Guntar chuckled as he heaved the struggling morning bag over his shoulder and slipped from the dark room. He raised no suspicion on his way back to his car and before long the bagged otter was safely locked in the trunk and on his way back to the dungeon.

--

Guntar dropped the leather sack with a thud on the cold dungeon floor as Duncan sat on a small cage covered in a black cloth to conceal its contents.

'This pudgy little fuck is heavy!' Moaned the Doberman as he flopped down on a bench and rested 'What did you get? That's a very small cage...'

'Oh you'll see, but let's see yours first!' Duncan grinned

'Pfft fine, but only because I think he might be running out of air in there'

Guntar unlocked the bag and then upended it - the otter tumbling out still cuffed and gagged.

'Mmmmhohh!' Mako cried into his gag as he looked up at the pair in fear and tried to scoot back on the stone floor

'Oh he is nice!' Duncan complimented 'Bet he'll make a good slut - already looks like a tailraiser to me'

Guntar put his foot on the squirming otter to pin him down and grinned: 'He'll he begging for cock when I'm through with him! But come on - what have you got in there?'

Duncan stood up and whipped the cloth off the cage - revealing Kitt within - still tied, sock-gagged and blinded.

'Ohh is that a fennec?' The dog asked as Duncan opened the cage and pulled Kitt out

'Yep, rare little buggers. Small but famously slutty - bet he can take the largest top. I'm going to find our at any rate!'

Duncan pulled the scarf off of the fox and he stared fearfully out at the two doms and the other abductee as he saw his situation for the first time.

'Hmmmgpphhh?!' He mumbled incoherently through his dirty sock-gag

'Quiet boy' Duncan said matter-of-factly as he raised the fennec's arms up behind his back - forcing him to bend over forwards 'So we have our 'volunteers' why don't we tuck them up for the night and get started on our challenge tomorrow?'

'Sounds good' replied Guntar 'We can have the final test tomorrow evening'

The rhino nodded as he hauled the otter to his feet 'I can think of a nice sleeping position for these bitches - grab a pair of collars, ring-gags and some chain and locks'

Guntar grabbed the stuff and each dom set about equipping their new pets. Kitt has his sock-gag and tape roughly removed and replaced with a ring-gag before he could say much and then a leather collar was secured around his neck. Mako, likewise, had his ball exchanged for a ring-gag and when he tried to beg in between Guntar just slapped him with the collar.

With both furs collared and gagged they were forced to the ground and made to lie top-to-toe in the 69 position. Each dom then took great pleasure in teasing each sub's muzzle with the others cock. Once they tired of this however they took a large padlock and locked it around each fur's balls - squeezing them tightly. From the shackle a short chain was run to the opposite fur's collar and lock in place. This held the pair with their cocks in each other's muzzles and unable to pull back. And with their paws still bound they were helpless but to breathe each other's musk and accommodate the hard cocks.

'Well boys' chirped Guntar 'bed time for us all, we are going to be nice tonight and let you make each other cum as much as you like! In fact of there isn't any cum on this floor by the morning you both get punished. Got it?'

The dog and rhino turned to leave but Duncan turned back at the door: 'Oh I I hope you both peed before we caught you because there is no getting up for toilet breaks!'

The two doms laughed as the heavy door was shut and locked - leaving Mako and Kitt to the least comfortable night's sleep of their lives.

--

---

Mako awoke in a different position to which he had fallen asleep. The fennic was gone and he was in a different room - smaller than the one from last night. He looked around through the lenses of some sort of hood that surrounded his head and saw the stone clad room packed with various pieces of bondage equipment and furniture. His heart beat quickly - he had allot of time last night to contemplate that he had been kidnapped as a sexual slave but waking up like this brought it back to him hard.

He rolled over to examine the rest of his situation but something stopped him as he moved and tugged at his neck - a collar was strapped around it with a chain anchored to the wall locked to the front. He shuffled back closer to the wall to create some slack and looked down over himself - he could feel several things around his body but he wanted to see them to be sure.

Around his knees and elbows were heavy leather pads and his paws and feet were contained within thick, locking, latex mitts and socks. This forced his paws into firsts and made them useless and the latex had puppy paw patterns printed into the top.

The otter shifted onto his knees and looked down to his crotch and even though he could feel it the sight horrified him... His cock was locked in a soft silicon cage secured with a padlock. It secured behind his balls and being as small as it was he knew it would totally deny any erection or release (it was partly blocking an erection now to the otter's shame).

Finally Mako turned to the hood around his head. It was made of heavy duty latex stretched tightly around him. At the bottom he could feel it had its own collar to secure it and a padlock hanging from it dangled against his neck. Atop the hood the otter felt even his ears encased in what felt like oversized latex sheaths which flopped about as he moved. Finally beyond the lenses a long dog-style snout stuck out and covered the otters own muzzle. It was shut with a zip but inside Mako could feel his maw still stretched wide by a ring gag - this one seemed to be integrated into the hood though.

The dungeon door creaked open and Mako found himself looking at the paws of the Doberman. He adjusted and looked up at the dog who had a frighteningly wide grin.

'Moring my little slut. So here is the deal, I know you're a subby little bitch at heart. You're going to be good, submit to me and do whatever I say without question - pleasuring me or whatever else I ask. We are going to win a little bet I have and then you get to live a nice comfy life as my little slut-pup.'

Mako looked away and blushed in humiliation and fear.

'And you don't have a choice in the matter!' Guntar snapped as he reached out and forced the otter's head back around 'Oh and you never look away while your Master is talking to you. You just earned a punishment, good start, now turn and present your rear.'

Mako froze in a mix of fear and stubbornness.

Guntar sighed at the otter's lack of action. He unlocked the chain on his collar from the wall and yanked on it - pulling Mako from his knees onto all fours. He then used his foot paw to force his chest low to the ground and moved around behind. The dog knelt down behind the otter and grabbed his cock cage, pulling it up and using it to raise his ass into the air.

'You want to play it that way, fine.'

The Doberman grabbed a small leather ball strap with a little box attached to it. He stretched the otter's balls away from the CB and fastened the strap tightly around them. He then grabbed a puppy-tail butt plug and lubed it up by spitting on it and then on the otters exposed hole. Mako was to intimidated to move from his embarrassing position but he lowered his tail to try and cover his hole.

'No!' Guntar snapped as he pulled the mustelidae's tail out of the way again and gave his cheeks a hard smack with the other paw

Mako yipped as he was struck and pulled his tail up to keep it out of the way. This wasn't good enough for the dog though as he fetched a tail cuff and used it to secure the otter's rudder to his collar - not giving him a choice but to expose his hole.

Guntar grabbed the plug again and without re-lubing it he put its tip to the otter's ring and pushed.

'Nughghhhhhh! MHHHHMPH!' Mako moaned in pain as the nearly dry rubber plug spread his hole open

He had played with naughty toys before but this plug was much bigger and his eyes watered as the dog kept pushing it relentlessly. Just as Mako felt the plug getting too much to bear it suddenly passed its biggest point and his rear sucked it in until it locked within him - the rubber tail part sticking up.

'Much better, but you were a bad pup, so...'

The Doberman took a remote and pushed a button on it, suddenly electricity shot through Mako's balls and radiated pain through his entire body

'Bad dogs get shocked'

Guntar held down the button again and Mako fell to the floor and writhed in agony - whimpering through the ring gag.

'Now. Are we going to be a good dog?'

Mako looked up and nodded his rubber clad head eagerly trying to avoid more pain. The Doberman smiled and unzipped Mako's muzzle - exposing his gagged maw.

'You're drooling like a good bitch so let's put that tongue to use...'

Guntar grabbed the chain attached to Mako's collar and sat on a rubber padded bondage bench before using the chain-leash to pull the otter over to him. Mako had to crawl on his belly but obeyed as best he could in his restraints. Guntar pushed his left foot out, it's sole a little dirty from the dungeon floor (Duncan and Gutnar never wore shoes in the dungeon or even clothes beyond fetish ware).

'Lick it like a good boy' the dog said as he put his paw into the rubber muzzle of the hood - hovering it centimetres from Mako's gagged drooling maw

'Ugghh' Mako choked in a mixture of disgust and hesitation but a quick yank on the chain dealt with that as one of Guntar's clawed toes pushed into the otter-pup's mouth

'Lick it' the Doberman commanded again, this time brandishing the electro remote as Mako looked up at him in humiliation

The otter finally relented and his tongue lapped out over his captor's sweaty and dirty toe. Guntar let him lick for a good while before pulling out and pressing the base of his sole to the otters gaping snout.

'Ukgghhh' Mako choked again but he was learning it was easier to do what he was told and lapped submissively at the dogs dirty paw

Once satisfied Guntar made him repeat the process with the other paw and by the time that was clean Mako was snivelling and whining like a submissive bitch. Delighted with his progress Guntar moved things on a step and ordered his puppy to sit up to attention. Mako was not familiar with these positions but he did the best he could to push himself off the ground and balance himself on the plug in his ass as he sat up and raised his head. Guntar pushed forward on the bench and pulled his bitch forward by the chain until his heavy musky canine balls were resting on top of the otter's fake rubber muzzle. This gave Mako a good whiff of the alpha dogs scent and he mewed submissively in the presence of the dominants scent.

'Get used to the musk boy, the only thing that will be cleaning my balls from now on is you. Get to work.'

The dog manoeuvred so that his balls were in reach of the otters tongue and Mako dutifully got to work - lapping out over the Dobermans nuts. The dog's balls tasted as strongly as they smelled and Mako cringed with each lap, though he was more overcome by the humiliating nature of the act rather than the taste alone.

As the otter-bitch worked Guntar's penis slowly emerged from it's sheathe and stood to attention directly in front of Mako's eye lenses - dominating his vision. The cock must have been a good 8 inches and sported a classic canine head and a knot at the base which was yet to grow. Mako watched the hard cock bob back and forth as he worked, fearful of where it was going next but he would not have to wait long to find out.

Guntar silently pushed the otter away from his balls. He gripped his furhood at the base and nodded down at it - still not saying a word. Mako knew what was required of him and with the little black remote only a few inches from the Doberman's right paw he knew not to keep the dog waiting. He came forward and angled his head as to take the tip of the red shaft into his fake-muzzle. Pushing down slowly he soon felt the tip push beyond his ring-gag and he paused to let his tongue flick out and pleasure it as well as he could. The otter-pup was encouraged when the Doberman moaned softly at the stimulation and he pushed on, taking more of the shaft in and licking down its length. Guntar let his bitch work without much input but he was quickly becoming very horny and he didn't know how much longer he could last without taking control again.

Mako started to bob up and down as he licked but with the ring-gag preventing him using his lips he could only do so much. Guntar finally reached the point where he couldn't take the teasing anymore and he needed to get off. He grabbed the back of the rubber clad otter's head with both paws and suddenly pulled him all the way down his shaft. Mako's nose slammed into the dog's musky crotch but the musk was the least of his concerns as several inches of the canines cock had been forced down his throat. He gagged and tried to pull back but the alpha's paws held him firm and Guntar wrapped his foot around the chain - also using it to keep the otter impaled.

Finally after several airless moments Guntar let the otter up and he gulped for air through the ring gag. The relief didn't last long though as the canine forced him back down and then started to hump - fucking the otter's throat.

'Ohhhh you're a good puppy, you're going to make Master proud.' Mused Guntar as he worked - nearing his climax all the time

For Mako the words merely added insult to injury but there was no way he could resist at this point.

'Uhgghhh g...good puppies get rewards! Good p...puppies get cum! Ughghhhhhhh' Guntar moaned as he came and suddenly pulled out

The first spirt of his orgasm hit the back of Mako's throat but as he pulled out most of it sprayed on the inside of the muzzle and against the front of his rubber hood. The otter blushed hard under his mask as he was marked by his new owner. The strong salty taste of the dogs cum overpowered his senses as he tried to swallow with the gag still in his maw.

Guntar patted the whining otter on the head as he stood up - still enjoying his afterglow: 'Well, I had a punishment predicament all lined up for you to sleep in but you are going to win me that challenge my subby little pup-slut so you get a nice night's sleep...'

The dog moved over to a storage unit and retrieved an odd looking black device - it was like a saddle with a wire coming out of one side. Guntar plugged the device into the wall and then retrieved a familiar looking dildo.

'Good boys get to feel Master all night!' he chirped as he secured the replica of his own cock onto the saddle-like machine

The machine's purpose was pretty obvious and became even more so as the Doberman bent his sub over and removed his dog tail-plug with a 'plop'. He then lubbed up the dildo on the machine and beckoned his puppy over to it.

'Sit.' He simply ordered, pointing at the long dildo

Mako crawled over and got to his feet before crouching over the saddle - the lubbed tip of the cock pressing against his already stretched entrance. He lowered himself down slowly - the dildo pushing deeper than the plug had. He came to near the base and suddenly realised the difference between this replica and the cock he had just sucked... the dildo had the knot at full size. The otter stopped dead as his ring hit the top of the knot. It was even bigger than the plug and he was going to struggle to take it.

'SIT' Guntar snapped, not caring about the otter's discomfort

Mako gritted his teeth against the metal of the ring gag and let his weight drop completely. His rear slammed down over his own weight - his tailhole stretching wide around the knot as it popped in and locked within him. The dog smiled as he bent down and strapped each of the otter's legs to the side of the device in a kneeling position - ensuring he could not get off.

Guntar fetched a remote like the electro one and Mako flinched, fearing the shock but when the dog flicked a few switches he felt a different sensation - the dildo had started vibrating. Guntar ramped up the power and then selected a pattern program. The dildo started to pulsate with vibrations in different strengths and frequencies and Mako moaned as pre started to drip from the end of his cage onto the top of the device.

'Enjoy pup, big day tomorrow, you're going to make me proud!'

Guntar turned and left Mako in the dungeon - securing the heavy door behind him as he went.

--

Kitt awoke with a terrible cramp in his arms. He wasn't laying on them but trying to move he found them bound tightly behind his back and encased in something right up to his shoulders. The small fox pulled himself of the cold stone floor using his stomach muscles and look around over his shoulder. His arms were secured in a heavy leather arm binder which was secured with buckles, straps and locks crisscrossing his chest. It even terminated in a heavily padded ball compartment which held his paws together in tight fists.

One thing was for certain, his arms were not getting free and Kitt moaned into the large ring gag still strapped into his maw as his muscles cramped. Other than that though he wasn't restrained though which somewhat surprised him considering what he had seen of the rhino so far. And speaking of Duncan...

'Right slave you're going to do exactly as I say.' The rhino said as he slammed the dungeon door behind him 'You're going to obey or you're going to suffer. And I have a little something in mind to demonstrate...'

Duncan moved over to a storage closet and returned dragging an odd looking device. It consisted of a heavy metal base with a spreader bar passing through the middle and stretching out on each side - ending in a shackle. In the middle a short pole stuck up with some sort of attachment at the top.

Kitt stared at the device but he was pretty sure he knew what it was for, and it didn't surprise him at all when the rhino produced a large knobbly dildo. It must have been at least 8 inches long and had three bulbous knots along its length starting just after the head. They increased in size from the top down and the last knot looked formidably wide.

Duncan smirked as he mounted the plug on the device and squired a bottle of lube over the top: 'OK slut you know exactly what to do, it's in a fennec's blood - so sit on that fucking dong'

'Hmmmmph?' Kitt grunted in disbelief yet he did nothing

'Failing me already' Duncan sighed as he grabbed a bullwhip off the wall 'GET THAT FUCKING COCK UP YOUR SLUTTY REAR'

CRACK

Duncan cracked the whip on the floor, it didn't hit the cowering fox but it came close enough to frighten him into action. Kitt scrambled to his feet, groaning as his arms strained against their horribly tight leather confines. He approached the device and waddled around it, wondering how best to get himself down on the dildo.

Looking over his shoulder to position himself the fennec squatted over the dong and flagged his tail. He stopped with the tip just resting against his tailhole and looked up at the rhino - hoping for a last minute reprieve. It didn't come; Duncan simply brandished the whip and gave his captive an icy glare.

Kitt gulped and closed his eyes as he started to lower himself down. His ring stretched wide as he impaled himself and let the first ball of the dildo slip into him. He rested for a moment in position before a nudge from the rhino spurred him on. The fox sunk down on his trembling legs and with some effort took the second, much larger ball into his rear. This time as he panted and rested he almost thanked the rhino for lubbing the toy up so much - almost.

'Last one bitch' Duncan grumbled as he tapped the whip on his size

'Hmmphhh'

Kitt grunted in discomfort as he attempted to lower himself again - this time finding the last and largest bulb much to big - pretty much too big to even attempt. The fox needed to get off his cramping legs though and decided to switch to his knees - his penetrated ass low enough down the toy to attempt such a manoeuvre.

With some wobbles and stumbles the fennec managed to switch on to his knees, this had the effect of forcing him heavily onto the final bulb of the plug but he still couldn't take it even with some of his weight resting on it.

'You will take that final knob fox, trust me, you just need a little encouragement' the rhino taunted in a voice which worried Kitt

He knelt down behind the fox and used a padlock to lock a ring on the bottom of his armbinder to a ring on the heavy iron base of the device. This stopped kit for rising up far enough to switch back onto his feet, effectively locking him impaled on the dildo.

The rhino moved away and collected what looked to Kitt like a gasmask - it was made of rubber that stretched around his entire head and had tinted lenses and a filter at the end of the snout. The filter looked a little odd though; it had some lights on it and looked to high tech for a normal gas mask.

'Clever stuff we got here boy, Bluetooth and all sorts' the rhino said as he fitted the mask to Kitt

This confused the fennec even more but the large dildo his body weight was resting on was a more pressing concern at this point. That was until the rhino pushed a button on a small remote. The mask beeped and then suddenly Kitt felt the intakes close and his air cut off.

The fox had just exhaled and panicked, shaking his head from side to side as he sucked desperately for his next breath. The rhino chuckled at his victim's distress but released the valve again remotely as kitten really stated to struggle. The fox gulped down breaths and stared up at the rhino with contempt through the darkened lenses covering his eyes.

Duncan just snorted and laughed: 'OK slut let me explain how this works. The lowest knot on the dildo operates an electronic switch when you hump up and down on it that slowly allows fresh air into a rebreather bag, which is all you will be breathing from for a while.'

The rhino stepped forwards and screwed a small rebreather to the intake of the gas mask. This made Kitt's breaths more laboured but for now the air was still relatively fresh.

'However since you have not even taken the last knot yet you can't operate the pump at all! I would say you have about 5 minutes if air to get it inside you and start humping before you pass the point of no return.' The rhino looked up at a clock on dungeon wall 'so that's what I'm going to give you.'

With that the rhino left the dungeon and locked the door behind him, leaving Kitt bound tightly, impaled and breathing already dead air.

The fox huffed into the sealed rubber bag in sock and unbelief - how could he possibly pull this one off. His ass burned with pain as his body weight pushed down on the dildo - gravity trying to push him down onto it. He tried to push himself up a bit on his legs and wondered how he could possibly apply more than his body weight to force the knot into himself and if his rear would even be able to take it if he did.

Deep down the fennec knew what he had to do but fear and pain was stopping him from thinking about it. As the air in the bag got hotter and thinner though he eventually decided to act. Lifting himself on his legs slightly he rose off the plug a few inches (but the second knot was still within him) and then dropped back down.

---

'Hmmmnnphhhhhh' he whimpered pathetically through the gag and mask as his rear slid half way down the third knot and his hole was stretched wider than it had even been.

It was not enough though, he still couldn't get down and activate the pump. He tried again and again but could not get any further and as his ass got more and more sore and his air more and more dead he found it harder to lift himself with each attempt. Eventually he just sat impaled, puffing hot dead air from the bag. His mind swirled in asphyxiation and his vision blurred.

He suddenly felt the mask being removed - he wasn't conscious of the rhino coming in but he had and he looked pissed. The fennec panted frantically as his airways cleared and he got oxygen back to his brain.

'I don't think you understand SLUT, you do with your slut rear exactly what I tell you to and you couldn't even take a toy to save yourself - Master had to rescue you. Disgraceful'

Duncan unlocked Kitt's arm binder from the base of the device and then pulled it up - forcing the fox to scramble to his feet and literally jump off the toy as the stress on his shoulders became unbearable. He landed in a heap on the floor and as he turned to look back up at the rhino all he saw was a whip coming down at him before blinding pain broke across his face and chest.

'Hmmphhhh!' Kitt cried into his ring-gag

'TURN OVER' the rhino snapped 'unless you would rather take it in the face present that ass for punishment!'

Kitt relented to the lesser of two evils and rolled onto his front - pushing his already abused rear up slightly to appease the irate rhino.

CRACK CRACK CRACK

A tear came to the fox's eye and he whimpered into his gag as the rhino took out his disappointment on the fennec's rear end, with the last agonizing crack the rhino threw the whip down at the fox who mewed in humiliation and pain.

He then moved over to a storage unit and retrieved a new dildo for the machine. As he disconnected the three knot plug and fitted the new toy Kitt got a good look at it. It was a thin head with a small knot following and looked pretty nice compared to the monster that had just been removed. The one oddity of it was a tube coming from the base.

'On' the rhino simply said and Kitt knew what to do

He heaved himself off the ground trying to keep off his whipped backside and hobbled back over to the device. He looked up at the rhino as if to ask why the new plug was not lubbed and the mean dom just spat on it in response.

Kitt moaned and squatted over the plug, sinking down on it with relative ease and onto his knees. The rhino approached with the gasmask and a smug gin on his face.

'Bet your happy to see this again!'

The fox struggled slightly but the rhino had no problem fitting the mask back onto him and he then plugged in the dildo's tube and various other tubes to the mask before screwing the rebreather bag into the mask.

'Ok its bedtime slut and I'm not convinced you are broken enough to win for me tomorrow so I'm going to keep breaking you over night. Let me explain. You will be re-breathing again and as last time to get fresh air you will need to fuck that toy good and hard for about 2 minutes. Simple with that little toy right? Well here is the difference, all the dead air released from your breather bag will be pumped directly into the plug - it's inflatable. I had a slut on this for 6 hours once and you should have seen the size of it when it came out! You going to be here until 11am tomorrow and its mighnight now so this will be interesting! Goodnight, and remember we win tomorrow or you are going to be here every night for the rest of your life'

With that the rhino left and locked the door up tight behind him.

--

Guntar lead Mako into the main dungeon on the end of a leash. The otter was still in his full puppy gear and all fours. He drooled constantly from the ring gag for which Guntar kept telling him off. For Mako the worst part was his cock still locked in its cage and the puppy tail plug lodged in his ass. He was subdued though; the torture of yesterday and the night had scared him into meek submission.

The canine took his 'dog' over to a wall of the dungeon which had anchor points on it and maneuvererd him so his rear was facing it. Hanging from the wall was a small cuff connected to an anchor point not by a chain but oddly by a thick piece of elastic chord. Guntar took the cuff in one hand he grabbed Mako's balls in the other before ratcheting the cuff tightly around the otter's sack. Mako squealed slightly as the cold metal squeezed around his balls and looked up at his master through his puppy mask.

'Don't worry pup, you will find out soon enough... In fact here they are now...'

Duncan and Kitt came through the door with the rhino leading the fennec on all fours and by a chain attached to his collar. He was also drooling from his own ring gag. The fox was otherwise devoid of gear however and under Mako's jealous gaze was not even chastised or plugged. When Duncan turned him around to back him up to the wall the otter got a look at his abused and stretched tailhole however and he was suddenly less jealous.

Even Guntar noticed the state of the fennec's rear: 'Whoa Duncan, what did you do to that little fox's butt!?'

'I'll show you later' Duncan smiled as he cuffed the fennec's balls securing him next to the puppy-otter

The two slaves shared a brief look for a moment before Guntar interrupted them: 'OK boys, time for us to settle our little wager, ready Duncan?'

The rhino nodded and the two doms moved a few feet away from their subs and turned their backs. The two were naked as always (apart from Duncan wearing a chest harness) and Mako and Kitt got a great view as both master's got down on all fours and pushed their rears up in the air. They used their paws to spread their cheeks open and each slave got a great view of his master's hole.

'Lick' Guntar and Duncan said in unison.

The fox and otter looked at each other again and then remembering the threat of harsh punishment for the loser of this test they came forwards on their hands and knees and tired to obey. Each was stopped about a foot short however as the chord linking their ball cuff to the wall pulled taught.

They both moaned into their ring gags but kept crawling forwards against the pain. Mako was the first to get his noise buried onto his master's rear wish his balls under massive pressure. The canine's ass was extremely musky but the otter knew he had a job to do and his tongue flick out through his gag and began to lap at the dogs hole.

Kitt reached Duncan a few seconds later but stopped short as the large rhino's musk hit him - he did not want to lick anything. Duncan growled deeply at his slave's hesitation which scared Kitt enough into pushing in closer, against his balls, and giving the rhinos rear a lick. If he thought the smell was bad nothing matched the taste of rhino ass. It was so bad Kitt retreated back to the wall and cowered in fear.

'You little shit, get up here and LICK' snarled Duncan but the fennec refused

'Mmm' Guntar moaned in pleasure as the otter kept slurping at his hole obediently 'I'm not sure if you can't break sluts Duncan or your ass just smells terrible but you lost!'

'No no no!' Duncan cried in anger as he got to his feet and grabbed a cattle prod off a nearby table

As he approached Kitt trembled back against the wall in terror. The rhino first struck the fox on the head with the metal prod and then jabbed it into his crotch and shocked him which made the fox writhe on the cold floor and wail into his gag.

'TURN AROUND. This is going up your FUCKING HOLE BITCH.'

Kitt turned over as tears ran down his cheeks but Guntar stepped in before the rhino could make good on his threat: 'Now now Duncan I will see to your loser's punishment'

The dog pulled the prod away from his friend and from behind put him into an arm lock and then secured his hands behind his back with a set of paw cuffs.

'And I'm certainly going to see to this losers punishment' the Doberman smirked as he led the struggling rhino over to one of the small cells and bundled him in before closing the self-locking steel door.

'Puppy you won for me! You're going to get a nice reward now and I will refrain from torturing you for 24 hours haha!'

Mako blushed under his hood at the praise. He knew the dog meant the 24 hour comment to tease but at this point a day devoid of torture looked like a pretty sweet deal.

The dog went over to a storage closet and returned dragging a stockade with him. The heavy metal frame would hold its captive in a dodgy style position with fixed shackles around the furs wrists, ankles, knees, chest and neck. This would leave the victims rear exposed and pushed up in the air. Guntar opened all the shackles and whistled at Mako who responded with a soft yip and tired to move over to the stocks. He was stopped short however by his ball cuff and the elastic - which exerted a sharper yip from the otter-pup. Guntar chucked and then released the otter from the wall - allowing him to move over into the stocks.

As the dog fastened over the shackles and locked them Mako wondered exactly what sort 'reward' he was getting here. Once finished Guntar shifted the now stockaded otter over so he had his back to the wall and turned to the still snivelling fennec.

'Was that nasty rhino mean to you?' He said with sickly mock concern 'well don't worry he will get what's coming to him. I dread to think of the state your backside will be in when he does get out though; it's already pretty sore isn't it?'

Kitt nodded in self pity.

'Well sorry but this punishment isn't going to help in that department. First of all you need locked, all slaved should be chastised I don't know why Duncan doesn't do it.'

Guntar fetched a silicon CB like Mako's and then unlocked the fox's ball cuff before making him lay on his back and applying the CB. Kitt hated the feeling of the cage around his cock but his primary concern was still his abused rear.

Guntar next produced an odd looking dildo. It looked like a standard canine penis recreated in rubber but at the bottom instead of a base it had a recess and some straps. Its function only became clear when the dog slipped it over the fennec's cock cage and it fit perfectly. He then tightened the straps and the cock hung securely from the fox's restrained package like a larger version of his own cock in rubber - it was a strap on.

Next Guntar grabbed four sets of paw cuffs and a set of smaller set of cuffs. He manhandled the fox over the otter in the stocks and positioned him as if he were mounting the otter and then used a set of cuffs to chain each of his four limbs to the stocks - holding I'm over the otter with his new rubber dong rubbing threateningly up and down Mako's ass cheeks. Guntar pulled out the otters tail plug with a 'pop' and then lubbed up the fennec's fake cock before aiming it at the otters hole.

With a quick swat on the ass Guntar made Kitt jump and thrust forwards, burying the 7 inch cock into the otter up to the knot. Mako moaned softly as he was penetrated but his ass was loose from constantly wearing the wider tail plug and the sensation was not entirely unpleasant. The Doberman then knelt behind the pair and fitted the smaller set of cuffs to their balls - holding them together and forcing Kitt to stay impaled.

Guntar then retrieved the last piece of the puzzle and it was probably the last thing in the world Kitt wanted to see - a fucking machine. The dog placed the machine behind the shackled fox and braced it against that wall. It was already fitted with a large and wide horse cock dildo which was smaller than the toys Kitt had been forced onto last night but its impressive length and girth still made the fennec tremble with fear.

Guntar lubbed the dildo up and levelled it with Kitts tailhole before pushing a button on the base of the machine which made it slowly and smoothly slide forwards and into the fox. Kitt gritted his teeth as the toy filled his insides and it stopped once it was at its fullest extent which felt painfully deep within him.

'Hmmnphhh' Kitt whimpered into his ever present gag

'Oh shush bitch, save your moaning for when I come back from punishing Duncan - we'll see how sore your ass is then!'

Guntar clicked another button on the machine and the large cock pulled back, then to Kitt's horror thrust in again - this time harder as it started to fuck him. It sped up and up and with each powerful mechanical fuck it forced the fennec's hips forwards and pushed his strap on dildo into the otter who mewed with each hump.

The canine patted Kitt on the head as he moved away and back to the cell holding Duncan. He opened the door and caught the rhino as he struggled out and fought.

'No Guntar! It's not fair! It's not my fault, rematch!' The rhino blurted

'Shut up Duncan, I'm going to have to deal with that mouth of yours'

Guntar raised the rhino's cuffed paws up behind his back - forcing him to bend over and making him easier to control. The dog then led his new captive out of the main dungeon and into one of the smaller side rooms. From there he led the struggling rhino over to a chain hanging from a pulley on the ceiling. The chain was hooked around Duncan's cuffs and then lifted with the pulley so the rhino was put in an extremely uncomfortable strappado position; forced to bend over.

The dog fetched a spreader bar and affixed it to Duncan's ankles which forced his legs wide apart and made the strappado even worse. It also had the effect of forcing the rhino to expose his ass which was exactly Guntar's intention. Duncan complained and moaned as his situation became worse and worse and Guntar resolved to correct this issue. His chosen tool was a jumbo sized red ball gag which he rammed into the rhino's maw and bucked tightly behind his head.

'One more thing before we get started puppy...' Guntar mused as he patted the rhino on the head condescendingly

The canine moved away and returned with another of the silicon cock cages he seemed so fond of. The rhino's eyes went wide as he saw his friend approach with the device. Guntar quickly and expertly fitted the CB around the rhino's mighty cock and even though it was a larger size than those used on the slave it was still an uncomfortably tight fit that made Duncan whimper as the strap was locked behind his sack.

Guntar stood back and determined his play-thing was ready. Grabbing a bottle of lube he slicked up his already semi-hard cock and brought it to full height before moving around behind the rhino and grabbing his hips. Duncan looked back over his shoulder but he knew what was coming and he wasn't sure he wanted to watch.

Humiliation hit the rhino almost as hard as Guntar's cock on the first thrust in. Guntar buried himself within his friend, turned captive, right up to his already engorging knot.

'Ohh breaking these bitches really makes you horny, but I bet that CB is making you appreciate that all the more right now' the dog teased

'Hmmmmphhh' is all the rhino could respond as he blushed and pre dribbled from the end of his cage

The dog began to hump the rhino hard and without regard for his partner's pleasure. Duncan's hole stretched wide around the dogs cock on each thrust and he whined into the gag each time. As a dom his rear was unused to such treatment and the rough fucking was quickly bringing tears to his eyes as well as dribbling pre from his own captive cock.

After only a few minutes Guntar was coming to a head and his thrusts were getting more powerful and faster. The dog made a conscious decision to knot the rhino and with his last mighty thrust slammed into the rhinos ring forcing his knot inside. Moaning Guntar sprayed his seed into his captive in long spurts.

Duncan blushed even more, his eyes still wet from tears of pain, this was the most humiliating thing that ever happened to him and why was his cock straining so hard to escape the chastity cage?!?

Guntar patted the rhino on the butt and pulled out with a yank, his cum dribbling out of Duncan's abused hole. He then walked around and held his cummy cock threateningly close to his victims face. Duncan tried to pull against the bondage but to no avail and for the first time he was glad the large rubber ball was blocking his muzzle.

That was until the dog reached behind his head and simply unbuckled it. Yanking it out, Guntar shoved his cock forwards.

'Clean it, or I'm going back for seconds' Guntar ordered and added the latter threat when the rhino rejected

Duncan sighed and gave in a final time as he opened his mouth and let the Doberman's penis in. It tasted of cum and ass but the rhino got to his task and quickly cleaned up the dog's dong. He received another patronising pat for his efforts as the dog pulled out and stood back.

'OK, that's enough for tonight and I know we said one night of punishment but... I think that CB is going to stay on you until you finally break that fennec - however long that takes!'

'WHAT!?!' The rhino stammered

'And you can spend the night like that too, that will learn you to make bets you can't win!'

With a laugh Guntar grabbed the ball gag off the floor and shoved it back into the rhino's muzzle before he had much of a chance to complain. He then turned tail and left through the cell door which was locked up securely, leaving Duncan in the dark, with his legs spread, arms tightly bound to the ceiling, gagged and with his friends cum still dripping from his sore tailhole.

The Doberman strolled through the main dungeon where the two captives were still 'enjoying' their double fucking set up. They both looked up at Guntar pleadingly as he passed but he simply responded with a wry smile.

The dog headed out of the main dungeon and ascended to the ground floor and then to the first where is warm comfy bed awaited. He loved winning.
