Mandy finds out she's a werecollie, and her first change happens at the worst time!


Mandy had lived a pretty normal life so far. The blue merle border collie had a suburban upbringing with two loving parents, but after graduating high school she'd given up the comfort of her home town to take a job in the big city several hours away. Life away from home was difficult but rewarding, and the money she made was at least enough to get by and feel like she was building a future for herself.

The biggest issue she faced after moving out on her own was just that - she was alone. She was cooped up in her condo all by herself in a city where she didn't have any friends and had no clue how to go about meeting new furs in this place that was so very different from what she'd grown up with. It was so lonely spending her days in that condo that she felt a spark of relief each day when she got to go to work!

Something had to change. Her mother told her to get a boyfriend, but she wasn't sure how to go about it in the big city. So many furs that she came across seemed sketchy at best and she was worried about being taken advantage of. Her father, on the other paw, recommended that she get a pet of some sort, which seemed like much less of a hassle than dating.

She started looking around for a faithful companion right away. Of course she was only looking for a dog from the beginning, as she'd never be caught with a stuck-up feline! Almost serendipitously the very day she started looking she noticed several flyers posted around the complex she lived in. Had those always been there and she just hadn't noticed before?

"Pure bred border collie free to good home! 2 years old, all shots current. Need to move at the end of the month and can't keep him unfortunately, he's very nice and well-trained. Requires a lot of exercise and attention! Call or text if interested XXX-XXX-XXXX."

That was about a month ago. Since then the pure black and white collie had become her constant companion, sleeping in her bed and waking her each morning for work, whining wistfully as she left each day and greeting her with such excitement each evening when she got home that surely the dog must've thought she was never coming back! He'd had a long pedigree name before, but she decided to just call him Rowdy due to his sheer energy and exuberance, a moniker that he took to quickly. It was challenging to care for him and he needed to be taken on a good long run every night or that very energy would be put towards keeping her awake!

Last night was like any other. She took Rowdy out for a run until they were both exhausted and then the two of them curled up in bed and fell asleep. The moon had been strikingly brilliant lighting the way for their evening run, full as full can be and seeming like it was double it's normal size as it rose low on the horizon. She had no idea that it was drawing her attention so much more fiercely than normal, beckoning and calling out to her..

Rowdy woke her up as usual, only it was still completely dark out other than that moon hanging high in the sky, shining in through her window. She looked up at the dog as he stood on the bed and licked at her snout, but as she awoke she started to realize that something was strangely amiss. The first thing she noticed was that she was finding it incredibly difficult to get her vision to work the way she was used to, everything was a bit blurry and out-of-focus no matter how hard she tried to will her eyes to work.

She figured that she should get out of bed for a while, maybe take Rowdy for a walk and see if the problem fixed itself. It wasn't debilitating or anything, just something about her vision was most definitely.. off. She twisted out from under the covers and onto the edge of the bed, leaning forward and kicking out her legs to stand, but instead of the expected result found herself clumsily tumbling off the bed onto the floor with a loud bark! The other collie followed her right along of course, seeming very interested in whatever Mandy was up to.

She rolled around on the floor, getting all twisted in her nightgown, the sole garment she wore obscuring her vision until she finally managed to wriggle and squirm free of the thing. It was only then that she looked over herself for the first time, jumping in jarring surprise and confusion as she seemed to have turned into a feral version of herself while she slept! She tried to speak or cry out for help, but the only sounds she could manage were barks and whines, so she barked out as loudly as she could, scratching at her closed bedroom door trying to get out.

Rowdy became very excited by the barking, commotion and sudden presence of a new dog that somehow seemed so familiar at the same time, and it didn't take long before he was barking along with her, scratching at the door like it was some sort of game. She whined as she just wasn't tall enough to reach the doorknob even when she stood up on her hindpaws, but Rowdy probably was given that he was at least half again as large as her, a good few inches taller at the withers and probably twenty pounds heavier. But how ever was she supposed to teach him a new trick like this?

The feral male had other new tricks on his mind though and wasn't particularly concerned about his former master's consternation. He'd caught her scent briefly at first but given the passage of time that warmly intoxicating odor became harder to ignore until he was completely fixated on it, drawn to it's source and brazenly pressing his cool snout right up under her tail. She was distracted, leaning up against the door trying to reach the knob in futility when she felt his cold nose and hot breath pressing right up against her pucker, definitely a bit surprised and embarrassed but she figured that's just what dogs do so she didn't think much of it.

In another second that same snout is pressed firmly right up against her spade-shaped canine vulva, broad tongue stroking over it several times and just barely teasing inward against her slit, tasting at her heat directly from the source and revving up the already excited dog. Mandy huffed and gasped, the unexpected sensation sending her down to all fours as her pet kept licking and sniffing at her spade, her tail uncontrollably arching and curling up over her lower back. Wait, was she in heat? She hadn't been in heat before she changed. She whimpered in confusion and forced herself to twist away from Rowdy with some great difficulty, sitting back on her haunches and looking down between her legs to see the unmistakable sight of her puffy, slick and heat-stricken sex. Her excited pet seemed all too eager as well, dark red tip poking proudly from his thick sheath hanging beneath the virile male.

She lays down on the carpeted floor thinking it the safest position, but with Rowdy already having had a good scent and taste of her he wasn't willing to give up so easily. He barks and nips at her haunches and tail in what seems playful at first, but as his excitement and frustration build rapidly turns towards aggression. When she twists and tries to nip back at him, giving him a growl the larger dog nearly snarls back at her, a sound she'd never heard from her pet before that makes her whimper and cows her. She tries to speak again but can only whine and bark, if only she could just say "No!" in her own voice she's sure he would understand..

Ouch! A few nips to her inner thighs are particularly rough, then Rowdy grips her tail in his jaws and fiercly tugs upward, her whole hind end following as she yelps and winces! Before she could even try to think of what to do next the eager dog mounted, heavy weight pressing down over her back while her pet's paws wrapped down around her haunches and wedged themselves along her inner thighs, giving him complete control of her hind end. He nipped and licked along her nape while thrusting in wild exhuberance, his pointy hard cock roughly nudging along her hindquarters and all around her spade.

She barks and tries to squirm out from under the larger dog, but her bark is answered with a firm growl and his grip on her is steadfast, following along with each step she tries to take until she's stuck in a corner of the room with no place else to go. The wildly humping feral suddenly finds his mark, the bitch beneath him yelping out a sharp protest as her spade is pierced and split wide by a canine girth that rapidly expands into her, stabbing deeper with each thrust as she feels his hefty balls smacking roughly against her vulva.

The door above her pants and huffs excitedly while all she can do is whimper and duck her head, folding her ears submissively. The larger dog's firm grip around her haunches pulls her right back against him to counteract his powerful thrusts rocking her smaller frame forward, each stroke of his feral length along her bare insides applying a wonderfully amazing pressure right against her clit that she tries to ignore but simply can't. Her eyes half-lid and then shut as she gives in to her fate, gives in to what this new body seems to want, and gives in to her new alpha.

The tags on Rowdy's collar jingle and chime each time he mercilessly pounds his feral girth up into her fertile pussy, the bulge at the base of his cock quite suddenly slipping from his sheath and squeezing past her vulva eliciting a loud whimper from the bitch. She knew what that meant. She could feel her vaginal muscles uncontrollably contracting and clenching down on the knot, massaging the swelling bulb while trapping it inside. He'd knotted her, shit! She winced and yelped as the thing just kept getting bigger and bigger, meanwhile Rowdy kept up his rough jackhammer thrusts that jerked and rocked her body this way and that, tugging at her insides.

Then she felt it. First Rowdy's heavy furred balls pulled up against his body, then a wave of pressure traveled along the dog's swollen cock, throbbing and twitching wildly as it exploded from the tip, wave after unrelenting wave of fertile dogcum flooding her heated womb and completely inundating her ripe eggs. He dismounted quickly and turned butt-to-butt as she yelped in protest and pain, his fully swollen knot feeling almost as if it could pull her inside out! She needs to press her hips firmly back against her former pet to alleviate as much pressure as possible, and after a few moments most of the pain subsides, leaving only the sheer embarrassment of the situation she'd found herself in.

Rowdy pants happily, looking back at her and seeming so utterly proud of himself as he empties everything he has to give into the smaller collie for nearly 20 minutes, sometimes dragging her about with a yip and whine from the bitch. She wondered with some concern if she could get pregnant from this, a question she'd soon discover is a vehement yes, eight pups to make a full litter already in their beginning stages of growth in her flooded womb. At least he's a purebred, right?
