"Dan."

	The brown haired 19-year-old was unresponsive to the gruff, gravelly voice coming from behind him. He was distracted, his thoughts quite distant from the kennels where he worked. An aged hand came down on his shoulder and startled him to awareness. 

	"Dan! Did you hear me? I told you 1 and 6 need to be cleaned 10 minutes ago, and you're still just sitting here! Get your ass in gear!"

	He jumped to attention, standing up out of his chair and turning to face the source of that deep voice, "Sorry, sorry! You're right Dr. Wyrick, I didn't hear you the first time. I'll get right on it!" 

	His boss nodded, "You'd best clean your ears out while you're at it, too."

	Dan simply nodded and walked off to do his job. He'd learned not to respond when the old man made comments like that or he'd just open himself to more of the same. There was simply no winning with old Dr. Wyrick. The doctor wasn't quite elderly, Dan guessed he was in his 60's but was very much afraid to ask. He was also stubborn as a mule and insisted on still being called "doctor" even though he'd retired from his practice over a year ago to open Wyrick Family Kennels. 

	The teenager got to work cleaning kennel number 1. There were twelve kennels in the small building marked 1 through 12, split evenly on either side of a wide central hallway. Two larger breeding kennels labelled B1 and B2 sat at each end. The facility entrance was down one end of the hall, a door at the other bearing a sign that read "Dr. Wyrick, MD PhD." 

	Cleaning the kennels was by far the worst part of Dan's job, but he'd been working there for a half a year now and had mostly gotten used to it. Each of the kennels had a small indoor section with a doggy door connecting to a larger run outside, individually fenced in for each canine. Kennel 1 housed a German Shepherd stud, purebred and well-behaved. Dan was easily able to direct the dog out the small door so that he could wash the rubber floor mat covering the inside part of the kennel, then brought him back in to clean up the dog's grassy run.

	Why was he still working here? Dan couldn't help but wonder to himself as he finished up with the shepherd's kennel and walked the hall towards number 6, bucket of soapy water in hand. The job was hard and he wasn't even really a dog person! He liked them well enough, but never had any ambitions past maybe getting a pet one day when he could afford a bigger place. 

	That was it, the money. Right? But surely there were other jobs he could do that he'd be better for, maybe even get paid more, too! He didn't even have any experience working with dogs before this gig, he'd never have gotten it if not for Amy!

	Amy Wyrick. The very thought of her made his heart flutter and skip beats! Her cool demeanor, beautiful eyes and soft voice were enough to set him off every time. They'd never gotten together or anything - he was too insecure to make such overtures in the past. She was just his sort-of-friend from High School, though he'd had the biggest crush on her for years and always felt like he was just waiting for the right moment. When she mentioned working at her dad's kennels and that they needed an extra few employees, he jumped at the chance to get closer to her. 

	They worked together some and he did get to know her better, but now Dan was worried that he might've missed his opportunity. A few months ago the 18-year-old doctor's daughter left for college and he was too shy to even ask for her number before she went! She promised that she'd come back home for a few weeks and visit the kennels on winter break, which was right around the corner. He told himself that he wouldn't waste another chance with her. She was still just about the only thing on his mind, though he hadn't seen her in months.

	He tried to focus back on the task at hand. Kennel 6 housed a Border Collie dame, the first permanent female resident of the facility. They'd run mostly as a stud service up till now, though Dr. Wyrick always made clear that he intended to breed his own once he found the right dogs. She was the start of that, and over the past week she'd went into heat. The need to find a suitable stud was urgent, a fact the doctor constantly bemoaned. 

	Though she'd been at the kennels for a while now the dame was still acting nervous and uncomfortable, Dan guessed that she was probably used to running the length of a farm or something. Dr. Wyrick ordered her kennel cleaned three times a day, and they also gave her extra food and took her out for runs, but it didn't seem to help much. 

	Every time Dan went to clean the Border Collie's kennel, she'd duck her tail and whine nervously as if she didn't know what was happening. He sponged off the floor mat with one hand while reaching over to pet and comfort her with the other, "Shhh, shhh.. it's okay Sidney, nothing to worry about.."

	"Bark! Bark!" The harsh sound rang out so loudly that it hurt his ears. "No! Bad girl, no bark!" He scolded her and with a whimper she retreated to sit in a corner. Though the dogs would still bark sometimes it was greatly discouraged, especially around people. He'd heard that Border Collies were one of the smartest dogs, but she still barked at him like that every time he'd clean her kennel. Why couldn't this one learn to behave?

	He finished up cleaning the collie's kennel and wondered what else he should do. It was only 15 minutes until he was supposed to get off and he was the last worker still there. He figured he'd head to Dr. Wyrick's office and ask if he could take off early, but stopped at the door as he heard the doctor's loud voice coming through. 

	"What do you mean you're not coming home?! For Christmas even?!" He was almost yelling. "You promised! We're your only family, if that's not important to you then... then.." He slammed the old-fashioned phone down with an aggressive clanking sound.

	Dan took a few deep breaths and turned to walk away, but before he could the doctor's voice called out to him. "You can come in now." He stuck his hand on the doorknob and slowly turned it, trying to collect himself. He definitely should act like he didn't hear any of that, right? But it had to be about Amy! He was torn and frustrated, putting on his best straight face as he walked into the office. "Uhhh, yeah.. I was just wondering if.." 

	Dr. Wyrick interrupted him and gestured towards a chair, "Have a seat." He seemed fairly calm after such a heated phone call, though Dan imagined that doctors had to be good at keeping their cool under pressure. The teenager obliged and sat in the cushy office chair opposite the doctor, a desk between them.

	"Amy's not going to be coming back." He put bluntly. "She made it clear that she doesn't want anything to do with this town or anyone in it. She wants to start a new life in the city and forget about this place."

	Dan shook his head in disbelief, "What?! She's so popular though, she has so many friends here.."

	The doctor nodded, "That's what I said. She said she's got new friends now."

	"Call her back, let me talk to her! Or just give me her number and I'll do it." Dan responded emotionally. "I bet I can get her to.."

	"No! I don't want to think about this right now, after what she just said to me. Drop it!" Wyrick aggressively snapped back.

	Dan felt a sense of strength and pride well up in his chest, responding more firmly than he every had in his life, "If you won't let me call her then I'm just going to drive up there tomorrow and talk to her, I know what dorm she's in..."

	Wire frame glasses slipped down the older man's nose as he lowered his head and locked eyes with Dan. It was rather unsettling and intimidating for the teenager. Wyrick sighed, "I don't want you calling her here. If you want her number, I have to go get it, I just have her on speed dial here."

	Dan perked up, "Yes! Sure, I'll wait to call her later.."

	Wyrick stood up, "Wait here." He slipped out the door and it shut behind him.

	The teenager was so happy that he was going to be able to talk to Amy again that he had no problem being patient at first. After a few minutes he started to get a bit antsy, though. If the doctor was going to take this long maybe he could just call her on the office phone? Dan looked over and tried to figure out how to speed-dial her but quickly realized that the old rotary phone didn't have that ability. What?

	He got up and decided he didn't have time for this nonsense, figuring that the doctor was stringing him along to keep him away from his daughter. He was done with this place, he decided right then. He was going to leave now, quit this job and never look back.

	When he tried to turn the doorknob it wouldn't budge. The heavy oak door was locked and completely impenetrable. He knocked on it as loudly as he could, "Dr. Wyrick! Dr. Wyrick, I'm locked in!" His knuckles rapped the door until they hurt, then he heard what sounded like a fan coming on somewhere in the ceiling. 

	There was no smell, no visible gas but Dan started feeling dizzy within 30 seconds, and after another minute his legs couldn't hold out underneath him anymore and he found himself back in the chair. His limbs felt like jelly and it was hard to move, hard to think. What was he doing here again? He tried to focus but every thought was transient, replaced by a new thought before he had a chance to process the first. It was like an uncontrollable stream-of-consciousness flitting through his mind, completely impossible to maintain a consistent train of thought.

	The fan shut off, another one briefly coming on seemingly to cycle fresh air back into the room before powering down as well. 

	Dan was vaguely aware of the door opening behind him and thought he might've felt a prick in his left arm, but couldn't be sure. He looked up to see Dr. Wyrick standing over him holding a syringe, which he put back in his pocket. The teenager tried and struggled to speak, "What is... I need, go home.." and he lifted himself up out of the chair with all of his might.

	"No, no, no.." Wyrick was able to gently push him back down in the seat, "You really can't stand or walk right now, give it a bit. The anesthesia should wear off in 5 or 10 minutes. It's only for your convenience and comfort."

	"Y-you... drug me?" Dan slurred his words so badly that they were almost unintelligible. 

	The doctor shook his head, "That's such an impolite way of putting it. I prefer to think of it as opening you up to new opportunities and experiences. Good luck, and have a nice night."

	Before Dan could react the doctor had left again, the door closed and locked behind him. He tried to jump out of his chair and lunge at the door at the last second, falling in a graceless heap on the cool concrete floor. His vision blurred and he swore that he could see hair growing on the back of his hands and arms. No, not hair.. black and white fur. Dan had never done drugs before - was this really what it's like? 

	Crack! Snap! A jolting sensation shot through his body and his bones felt like they were rearranging themselves, the anesthesia blocking most of the pain though it was quickly wearing off. What on earth was happening to him? He had to get out of here! He cried out for help knowing full well that no one was around to hear him, Dr. Wyrick had made sure of that.

	He stood up just barely, reaching for the doorknob and grasping at it with an increasingly canine paw that had no ability to grip, watching in shock as black claws grew from his digits. It quickly became too hard to stand and with a clack of claws against concrete floor he fell down to all fours, his hips completely rearranged into haunches. 

	His shirt fell down over his head, temporarily blinding him and making him realize that he was shrinking! He shook his head back and forth trying to get the thing off,finally succeeding only to notice that he was now staring down a canine snout! It kept growing out of his face until it reached full size, a cool wet nosepad at the end. 

	He stepped forward on shaky, shifting limbs which pulled his legs out of the loose pants and boxers he was wearing, standing there naked and looking underneath himself with a morbid curiosity. His legs shifted and feet fully became hindpaws. The last pink human flesh on his abdomen disappeared and gave way to soft white bellyfur, watching in shock and horror as his balls grew larger and turned black with little tufts of white fur. Finally the rest of his human anatomy was sucked up into an emerging sheath that grew thick and full, a whine escaping him as he could feel his cock changing shape up inside of him. 

	His hips arched and a red, tapered canine tip poked out from his sheath, verifying  that he was now a feral dog. He examined himself, covered in black and white fur. He was a Border Collie stud now, somehow. Just what the kennel needed! 

	He tried to yell, tried to call for help, but could only bark, whine, yap and whimper now! He jumped up on the desk with zero grace, almost fell off, and fumbled the phone with his paws until it fell off the base, then lowered his head to it. There wasn't even a dial tone! His blurred, somewhat unfocused canine vision followed to cord to see that it was unplugged. Dammit!

	He hopped back down onto the floor, grabbing the phone cable in his maw and trying his best to plug it in. He'd need to concentrate if he was going to succeed, but even now that the anesthesia had worn off it was hard to focus. There were so many distracting scents, and he could hear sounds through the walls of the other dogs in the kennels. He tried his best to plug in that cable, but it felt impossible. He just wasn't used to this body yet, everything was awkward and difficult. 

	The male Border Collie tried for what felt like hours to get that damn plug into the wall socket, growing more and more frustrated as he repeatedly missed or dropped the cable. He was unaware of the ways in which his perception and attention span had changed - only minutes had actually passed. Trying to focus on a complex task that his new canine brain wasn't wired for was incredibly taxing and draining. Combined with the stress of the transformation he'd just went through, he felt utterly exhausted. All the effort he could muster went into trying to stay alert and figure a way out of this, but within ten minutes the dog was passed out, fast asleep on the cool concrete floor.

**********

	A voice. He heard a voice, but no words. The voice seemed familiar, but different. He was so groggy that he could barely remember what happened. Was it a dream? His eyes slowly blinked open and he tried to focus his vision, looking down a black-and-white furred snout as a reminder that last night was very, very real. Before he could further process what was going on, a hand lowered and fastened a collar down snug around his neck, jolting him to awareness. Leash fastened to collar, the voice spoke again and a few firm tugs encouraged the dog to stand.

	He looked up and saw Dr. Wyrick standing over him, leash in hand. His hackles raised and he growled with ferocity and anger at what had been done to him! Before he could do anything else the doctor tugged his leash so hard that he was pulled up off his footpaws, snatched out of mid-air and roughly slammed belly-up on the office desk. Wyrick's hand closed down around his snout, firmly holding it shut while the other kept him pinned in place.

	Wyrick spoke, but the dog couldn't understand. He whimpered and whined submissively, a concept his brain could follow, but the doctor just kept talking. He'd given up, he was defeated.. he was supposed to be let go now! He looked up at the man and tried his absolute hardest to concentrate on what he was saying. It hurt his head a little, but the sounds finally started to turn into actual words.

	"Focus! I know you can understand me, just focus dammit!!" The look in the doctor's eyes changed as he seemed to realize that he had the dog's full attention. "Good, I can see you're still in there. You'll answer to Diz now, like that tag on your neck says, and you'll be a good boy. No growl! No bite! Bad dogs go to the pound! Nod if you understand me, I know you do."

	Diz gulped and whined, closing his eyes and nodding as best he could with the doctor's hand gripping his snout. That firm grasp released and he found himself no longer pinned to the desk, feeling a few gentle tugs on his leash. "Good boy. Come." He hopped down from the desk and did as he was told, led out of the office and down the kennel hall.

	The scents and sounds of the kennels were intense and overwhelming, his head darting this way and that, ears perking, while gentle but insistent tugs on his leash kept him heading in the right direction. Walking on all fours felt so surprisingly natural that he didn't find himself thinking much of it, unlike trying to plug in that phone cable which felt incredibly abnormal and awkward in this new body. 

	A tangy, musky scent caught in his olfactory and was so interesting and unique that his brain honed in on it to the exclusion of all other scents in the hall. What was that?! It made his tail arch proudly behind him as he walked with a confident swagger. Then he saw her. Sidney. Kennel 6. The skittish, blue-eyed Border Collie dame whose kennel he'd cleaned many times. The scent of her heat was impossible to ignore, and Wyrick was leading him right to her! A whine accompanied an uncontrollable lunge of his hips that made his canine tip poke out of his bulging sheath.

	The door to Kennel 5 swung open and before Diz knew what had happened, he was off-leash and locked up in the enclosed area. Only a fence separated stud and dame, nothing there to protect him from the constant assault of her intoxicating scent, shaking his head to try and focus on literally anything else.

	She came over to her side of the fence seemingly to greet him, the polite wag of her tail stirring her scent all around the kennels. He leaned forward and sniffed at her without giving a thought, cool snouts touching before a broad collie tongue swiped over his muzzle. It made him so very happy, his ears perking and tail wagging with excitement.

	Wait! This isn't right! The remnants of his humanity cried out from somewhere in the back of his mind, he wasn't a dog! He tried his best to figure out how to break out of the kennel, but that scent was so constantly distracting and a massive, rumbling hunger had started to build up in his stomach. He looked at the bowls of dry kibble and water sitting in the corner of the kennel. No! He couldn't! There was no way that he'd..

	His thoughts were interrupted by the sounds of crunching and a mediocre taste in his mouth. No! He felt a deep shame and embarrassment at eating the dog food, but at the same time the kibble satisfied his hunger and he couldn't stop eating until the bowl was empty! Next thing he knew, he was lapping at the water bowl to sate his thirst, making a wet dripping mess of his muzzle. Ugh! How could he let himself be reduced to this? At least he wasn't hungry anymore..

	Diz's ears perked at the sound of a kennel door opening, but it wasn't his. It was next door at Kennel 6, and he watched as one of the other employees put the Border Collie dame on-leash, Jan. He didn't know Jan very well other than working with her, she was a bit older than him and was married with kids. He watched as she led the bitch over to one of the breeding kennels, his eyes drawn to the dripping spade barely visible through the fur of the dog's haunches. He caught himself after a moment, looking away shamefully. 

	His sensitive ears picked up on footsteps coming down the hall, and he recognized them as belonging to the other kennel, Mike. Diz went to high school with Mike, and though they weren't close friends they were close in age and knew each other. Maybe he could help! He looked up at Mike as he opened the kennel door, leash in hand.

	"Bark! Bark!" Diz jumped and whined, trying his best to communicate with Mike. The handler shook his head and firmly scolded him, "No! Bad dog!" He reached down and fastened the leash to Diz's collar, a hand petting over top of his head and ears as he did so. "Come on now, be a good boy.." A few tugs on his leash ushered him out into the hallway, over towards the breeding kennel where he'd watched Jan take Sidney. Dammit! Mike just thought he was another dog!

	He struggled to think of how to communicate with his handler, his already primitive brain clouded with that potent heatscent that beckoned him irresistibly, stirring his loins. With a whine he was tugged into the breeding kennel, the door shut behind him, and he dared to take in his surroundings.

	Jan was sitting there on the floor next to Sidney, her leash tightened up to only give her a few inches of freedom, the human handler calmly talking to the dame, encouraging her and keeping her calm. When she saw them come in her hand moved over to the collie bitch's hind end, lifting the nervous dog's tucked tail and showing off the swollen canine spade between her legs.

	Diz tried not to look, tried not to breathe that scent, but firm tugs on his leash led him directly over to her until he could feel her body heat, humping at the air a few times as her estrus hit him from up so close. As if to make things worse, a hand came down atop his head and nudged his snout right up between her hindlegs, cool snout meeting puffy slick vulva that made him shudder and Sidney tense. He couldn't stop himself from stroking his broad tongue over that canine sex a few times, his heart pounding in his chest as he got his first taste of heated bitch.

	His forepaws were suddenly grabbed by one of the handlers, his front end lifted and pulled forward until he covered the bitch, instinct driving his hips to buck and thrust at the feel of heat against his loins. He whined out loudly - he couldn't let this happen! There's no way he'd let his first time be with a dog! The Border Collie stud shook his head and struggled with all his might, barking hoarsely when he tumbled off Sidney's back and roughly thumped down onto the rubber mat floor.

	The two handlers spoke, but Diz wasn't focused enough to understand what they were saying as he made his way back up to all fours, shivering at the cool air against the inch and a half of stiff canine arousal bulging out of his sheath. He was pulled forward and they tried to make him mount the collie dame again, but he fought with all his might, shaking his head and panting with exertion while he tugged against his short leash. Sidney joined him in protest, whining and struggling with her handler - it seemed like she was getting antsy and impatient.

	More words were exchanged and then he felt a hand on his head directing his snout back down under the collie dame's artificially flagged tail, holding it in place and keeping him there tight on his leash. He closed his eyes and whined, his panting tongue coming into contact with the bitch's sweet tasting spade. Before he knew it he was licking deep up into her entrance, her haunches lifting and arching right back against the attention as his feral instincts savored the taste of her pheremone-laden juices. 

	Diz's ears perked when he heard the sound of a drawer opening, but couldn't see much around him with his head buried in colliebutt. They weren't going to... they couldn't possibly, he thought. He tried to turn his head but was firmly held in place - he couldn't get his snout more than an inch or two away from Sidney's puffy spade no matter how hard he tried and it was dizzyingly intoxicating. He had to figure a way out of this! He had to control himself, he had to...

	He was interrupted by the feel of a latex sheath wrapping around his canine length. It was a collection cone! The shame that he felt was quickly replaced by the sensation of a gloved hand pulling his furred sheath all the way back behind his knot, then gripping right down behind the latent bulb and vigorously stroking along the sensitive area.  He yipped and whined as he couldn't control himself at all anymore, blindingly intense pleasure coursing through his canine form while his hips blurred into a frenzy, humping right into the collection cone. 

	It took mere seconds before the panting stud tossed his head back, whimpering loudly in a mix of embarrassed frustration and overwhelming pleasure. The initial hysteria of his pistoning hips slowed to the firm, deliberate grind of a stud who'd knotted his bitch, the collection cone filled with a hot spray of purebred Border Collie spunk while that grip around his knot remained firm.

	After another few moments the spunk that was filling the cone started to run clear and he felt the hand on his knot release it's grip and move away, followed by the removal of the latex from around his canine length. He whined loudly as he was left with his throbbing, engorged length exposed to the cool air, still spurting mostly clear fluid onto the rubber mat below. Another few tugs on his leash and a short walk down the hall brought him back to his own kennel before he could even process what had just happened, the chain-link door shutting him in.

**********

	Dr. Wyrick sat at his office desk, visibly frustrated. "What do you mean you did a collection?! I told you we weren't doing artificial with the collies!"

	Jan stammered, "I just thought, with the dame already.."

	Mike chimed in, "He was really hard to deal with."

	"Just make it happen." The doctor stated firmly. "These farm dog owners want a stud that can do full natural. He's inexperienced, that's all."

	Jan nodded, "Okay, first thing tomorrow we'll.."

	Wyrick shook his head, "We got what, 5... 6 hours left today? Let him rest a little and try again before close. He's a young stud, he can handle it."

**********

	Diz was so hungry after his ordeal that he ate a big bowl of bland kibble without even thinking it strange. No, he was much more embarrassed about the red, swollen girth throbbing down between his legs. It was drying out and getting sore, sitting on his haunches to more closely look at the veiny length. The uncomfortable dryness made him whine and shift his hips awkwardly. 

	He looked around to make sure no one was watching and did the only thing he could think of to help. With great reluctance and shame he ducked his head down between his legs, broad canine tongue lapping at his knot and canine length over and over again, the pleasure making him shudder while he soothed his aching arousal. He laid down to try and rest, but every few minutes he'd need to repeat the process, gradually getting more and more used to his new canine anatomy until it finally deflated and shrunk back up into his sheath. Exhausted and spent, he rest his head down on his paws and fell asleep.

**********

	The Border Collie stud was startled awake by the sound of his kennel door opening. He looked up to see Mike reach down and fasten a leash to his collar, gently tugging to get him to stand up. The handler said something, but all Diz could make out was "Good boy." At the very least the words seemed kind and encouraging, he could tell that much. The dog yawned and stretched groggily as he was led out of his kennel and into the hallway. Maybe it was time for a walk now? He felt a strong desire to spend some time running around an open field.

	He was caught off guard when the handler led him right back to the breeding kennel, finding Sidney there in much the same state as he'd last seen her. The door closed behind him and the lead on his leash shortened, the scent of heat in the small closed room immediately getting to him. He whined loudly in protest again - they weren't supposed to breed a stud more than once in a day! They must've made an exception, he thought as he gulped, able to taste the sweet fertile heat of that collie bitch dripping down the back of his throat. 

	The two helpers shared a few words and then Diz was pulled forward again, a hand coming up under Sidney's abdomen to hold her rump high in the air, another flagging her tail and wagging it a bit to make sure to catch the stud's attention. They had no idea he wasn't just a normal dog! No matter how hard he tried to look away his eyes were drawn up under that collie bitch's tail, a hand on his head once again pressing his snout flush up against her slick spade.

	His hips bucked and jerked, arousal straining from his sheath as a spurt of clear fluid splashed the stained rubber mat beneath him. His eyes watered at the scent of her unsated heat, tongue hanging from his open maw in an uncontrollable feral pant. Hands once again grabbed his forepaws and pulled him up atop the dame, then moved his paws until they wrapped down around her haunches. He whined and huffed, shaking his head but he was far too exhausted to fight with the strength he had last time!

	Despite his best efforts to resist the urge, his feral impulses and instincts were simply too strong and his haunches thrust forward until he felt his tapered tip brushing up against the slick, matted fur of Sidney's backside. His feral body was overexcited, buzzing with anticipation. Was he really doing this? Before he could question himself any further a gloved hand came up between the two dogs and carefully gripped his sheath, expertly guiding his slick tip to the puffy spade between the collie dame's hindlegs.

	Diz felt the overwhelmingly intense heat of her sex pressed right up against his bare canine cock, whining audibly as he was helpless to stop himself from roughly grinding and humping right up into her slick velvet tunnel. The most amazing sensation enveloped his growing length, the bitch's complementary anatomy perfectly stretchy while still gripping down snug around his girth. He humped into her deeper and deeper with each carnal jolt of his hips, a hand coming up on his rump and firmly pushing his haunches forward against her rear.

	He panted and huffed desperately, the trainer's encouraging hand on the inexperienced stud's hind end making sure he stayed as deep as possible while giving little chance that he could back out at the last minute. Diz wasn't even thinking about stopping, he was too far gone! Completely lost in the heat of the moment, his mind devolved until tactile sensations and instinctive imperatives were all that remained, forepaws firmly tugging the dame's haunches right back against his blurring hips as he felt her little fortune cookie forced to stretch wider and wider around his swelling canine girth.

	The bitch whined softly and ducked her head submissively, only further spurring on the eager stud to fulfill his primitive urge. His thrusts turned into short, aggressive jabs of his hips as his sheath bunched up against her stretched canine vulva, a whimper catching in the back of his throat at the feel of her muscular inner sex gripping down insistently right behind his knot! It felt so much better than the collection cone, his fervent humping slowing to a series of erratic, powerful jerks of his haunches.

	His dame let out a series of staggered whines and then yelped out loudly as the bulb at the base of his cock rapidly ballooned up inside of her, grasping vaginal muscles ensuring that the two dogs firmly tied. Diz's tail arched and flagged behind him, his vision nearly blacking out at the intense pleasure, Sidney's canine sex perfectly squeezing behind his knot and massaging all along his engorged length! It was all he could take, rough thrusts smashing his furred balls against her claimed honeypot, wave after wave of orgasmic ecstasy flowing through his body, each ending with a stiff jerk of his hips and hot spray of canine spunk!

	The handlers could tell that the Border Collies had tied and so without warning grabbed Diz's forepaws, moving him off the dame and dropping him down to stand on the rubber mat floor of the breeding kennel. The sudden motion surprised both dogs and made them yip in unison, a hand reaching in to lift one of the stud's hindlegs up over the bitch so they were properly standing butt-to-butt, a voice praising and calming the whining dame as he kept pumping her ripe womb full of fertile puppybatter. 

	Sidney's canine vagina was incredibly hot and tight, rhythmically gripping and relaxing around his swollen doghood, teasing and coaxing every last bit of lifegiving seed from his heavy balls - he thought his climax would never end! He had no idea how much time really went by, raggedly panting for breath and dizzy with euphoria. It felt like forever that he stood there with the two handlers, tied with his bitch as his many eager swimmers coated her ripe ova, filling her with a big, healthy litter. 

	The door to the breeding kennel opened and Diz looked up, trying to focus his vision. It was Dr. Wyrick. Words were exchanged and the two handlers left, leaving the dogs alone with the doctor. He waited a few minutes to make sure they were actually gone before leaning down to Sidney and petting her on the head, speaking to her. "Good girl." Diz could make out that much easily, but he needed to concentrate more to understand what else was being said to the collie dame.

	He continued talking, "I'm sorry it had to be like this, but you gave me no choice. You were going to leave! We can't be a family kennel without the 'family' part, right Amy?"

	Diz looked back at the bitch he was tied with, a shocked expression crossing his canine countenance. Amy?! The border collie dame ducked her head shamefully and he knew that it was true - the dog he'd just bred was the girl he'd been crushing on for years! It felt so wrong and so right at the same time.

	Dr. Wyrick pet over her ears tenderly, "I got you that boy you always liked, though. He was going to leave too, you know." He moved over to Diz, pulling a red handkerchief out of his pocket. "She said she was going to give you this when she left. I said it'd look stupid on you, but I guess it makes more sense now." He reached down and tied the cloth around Diz's neck - it smelled good and evoked faint memories that he couldn't quite place.

	He looked back again and noticed that Sidney's tail had started wagging, her eyes wide open meeting his inhuman gaze. She seemed.. happy? But why, how could she possibly be happy right now? He suddenly realized as he looked into her sky-blue eyes, she was happy because it was him! He barked out in elation as his tail joined hers in wagging excitedly, so happy that the girl he'd liked accepted him that it almost made up for the bizarre circumstances. 

	Before he could let that sink in too much the rigidly contracted muscles in Sidney's canine vagina suddenly relaxed and released the vise-like grip around his knot, his length audibly popping and spilling out of her sex with a lewd gush of excess fluid. She sat down, seeming rather unconcerned about anyone else's presence as she lifted a leg and stroked her broad canine tongue over her broken in spade. She'd been a dog for months longer than he had - maybe he should get used to it too. He sat, lifted a leg and followed suit, licking at his red, engorged length repeatedly.

	The doctor just laughed, "Looks like you two are already getting the hang of it. I wouldn't normally do this, but.." He stepped outside of the breeding kennel and closed the chain-link door, "You two aren't a normal breeding pair, either. I'll assume you can handle being together without being watched. If you want to spend more time together, then you better not disappoint me! Make lots of puppies!" He shut off the lights, footsteps disappeared down the hallway, then he was gone.

	The two Border Collies got up and approached each other as their eyes adjusted to the low light. Snout met snout, tender licks and nuzzles were shared. It was going to be an interesting night.
