No refusal excepted. - My mind was made up, our dogs getting a fuck on her tonight! [My wife that is] Oh yeah... Day after day she lets me watch the mutt lick her into an orgasmic stupor, but then refuses to kneel down for the poor fucker [With a hardon like a babies arm] to get it into her.

I'm not prepared to let the mutt suffer any longer, he gets her tonight regardless of her wants. As soon as he's licked her cunt into cumming, I'm gonna flip her into kneeling and hold her if necessary until he's got it into her sopping wet vagina. I mean proper fucking 'knotted' so she can't get away until he's emptied his balls up inside the fucking horny bitches womb, because with the cock he's fucking got hanging that's just where his puppy juice will finish up.

Lets face it, she's no innocent, now at 32 she's had a number of my mates knobs... Yeah, - she knows I know and seen her often taking them. - Well this time she's up for a real bruiser of a knob, Ten inches at least and thicker than any man she's managed up till now - and that's before the knot [The size of a mans fist] sticks her ass to the mutts while he drags her around the floor trying to un-knot from her.

Okay! I'm prepared to steady the fucker so as not to let him turn her cunt inside out! But that knots staying in her good-&-proper! ...The pattern never changes... we sit for awhile, she watches our mutt,he watches her out the corner of his eyes, her dress rises up her thighs, she eases her knicker's to one side, his tail wags, then she's got him trapped.

He slinks over to her, glancing guiltily at me as he goes, but like us men, the lure of the pussy is just too much! Then after a few tentative licks, he's at her good, at first she just keeps her knickers out of the way, then his tongue demands more and she 'A's' her fingers to hold the lips open letting his tongue sink into her pinkness. The thighs spread wider with each slither of his tongue up thro' her slit until with her body trembling she pushes him aside to allow her to strip off her bottom half. [Tail gently wagging] he waits for his next helping... the movement of clothes removing has lubed her vaginas entrance and now with relish he slurps deeply up thro her cunt slit making her belly jerk and tremble.

"Steady! Slower! Do it slower for mummy!" - Complying he steadies & she helps herself to more titilation now by easing her hood back from her clitoris allowing even deeper penitration of her cunt lips until now physically shaking all over, - "Not to quick, you're making me cum!" - For seconds she hides her clit from his demading tongue but as her excitement eases she again gives him full access to that bean until with her ass sliding forward off the seat she yelps and trembles in an almighty orgasm, in turn the dog licks at her cunt - long licks now taking in her cunt and asshole crease until in despair - "NO! - GOD NO MORE! - I JUST CAN'T HAVE ANYMORE! - FUCK I CAN'T!"

She moves to deny the mut anything else and with a stupid look on his face and 10 inches of hanging hardon he barks as if to be demanding she presents her cunt to him for fucking! - All the other times I've pleaded at this point for her to give it to him - But this time, I'm off my chair and grabbing at her torso, - "Over! Turn over you whore! You're his and I'm making sure he fucks you!" - In shock she - on steadying herself - hit my hardon inside my trousers - "No! No! Only yours, I told you - NOT HIS! - Its too big!

Her fight was less than I expected as I had her on her knees and with my full weight across her back held her flattend in the chair ready for our dog. - Watching he hesitated until reaching under him & smoothing his hard cock - "Come on you dumb bastard, I'm holding her for you!" - "Don't you fucking dare you sick bastard, I'll murder you when I get up from here!" - Quiet now as the dog went in to lick her super wet slit some more - "God No! Its to touchy, I'll pee! I swear it'll make me pee myself! NO, don't lick me now, please don't let him!"

I just done what was needed, slapping her ass cheeks I invited the dog to mount her and that's just what he did. - I knew the heat of his cock hit her entrance because I felt her jerk under me - "Fuck its so hot - don't let him, its burning hot - Oh! Oh! its going inside... Fuck! That's fucking hot!" - I felt her relaxing and dearly wanting to see that fucking hugh dark red piece of flesh sinking up inside my wife's cunt I moved back to watch.

Not moving, but with her head facing away from me she stayed as she was as this fucking hard dog cock was getting swallowed by her vagina. The shaft slid nicely up into her and as he gripped her hips so tightly she clearly now had no chance of getting out of a full on fucking I relaxed on the floor watching the spectacle of-dog-fucking-woman.

Now with his feet inside of the wife's he was certainly tall and big enough to have no problem mating with her, but as I watched his thrusting I admit I had reservations now of that fucking knot smacking at my wife's spread labias' - The more it slapped the wetter she got, but the fucking she was now getting clearly was being enjoyed by woman and dog as she now started pushing back at that thick shaft of dog cock.

"Fuck its fucking hot! He's farther in than any of... she realised what she was saying - well, its right in as far as it can go!" - What she didn't realise but I was seeing was her vagina was tantalizingly spreading open at the entrance and that knot was getting very much nearer to pushing past the tightness of her entrance. [I knew precum was drooling from my own cock,such was the spectacle] but by now I wanted that knot well and truly up inside her.

He not thrusting now and just pressed at my wife while she seemed to be pressing at him - "What's it like now?" - "Fucking gorgeous. Its fucking monsterous inside me" - "Are you glad I made you?" - "Don't ask... Yeah alright? Yeah I wanted too anyway, but it was scaring me, did you see how big he is?" - "Wow! What was that?" - I'd just watched as her now slippery pressing cunt had submitted to that fist size knot and my wife was truly knotted with the mutt - "Fuck that's nice, what ever happened! it just wonderful, no man can do that to me... What did he do just then?" - "Knotted with you, he's knotted!"

"AH! AH! Fuck! you wouldn't believe how that feels, he's fucking cumming like hell up in me, FUCK IS THAT HOT! and its shooting over and over - really hard squirts and its in my womb... He's coming right up in the entrance to my womb!" - The look on the mutts face was a picture. You could tell every nerve in his body and every brain cell he has was cocentrated on impregnation! - It was not immediate that he started trying to turn in her. - "FUCK! FUCK! What's he doing to me now?"

"Just trying to turn like dogs do. [I, looking at her entrance] I could see her vagina was having trouble coping with the fist sized knot turning. - I grabbed his body and stopped him from doing that while admiring the sheer swelling of her cunt as just inside it had coped with a massively swollen cock. But her vulva area with its now soaked pubes was larger and bulbus up towards her belly because of the hugeness his knot was impressing in her. - Then I noted a slight subsidence in its size and helped him turn in her and her cunt coped with this although it looked like it might [her cunts membrane] get pulled out with his knot.

He went to pull away from her now but as her entrance stretched but couldn't release the knot I held him & stopped him from pulling until with her entrance comfortably now coping & him shrinking I adjudged she was able to release him from her tunnel and out that facinating cock plopped accompanied by lots of her and his cum. He walked away strangely,  [As tho' his legs were disconnected] glanced back at her vagina and rear and promply lay licking what unsheaved cock was still protruding.

Still knelt as tho' her desires were now satiated, - "Want me to fuck it now?" - No reply, but her ass jerked slightly - I took this to mean - 'If you want too' and promply took the place of the dog on her back. Surprisingly my cock felt just fine inside the much stretched vagina only moments before and with all the excitement of watching them, I - in turn in no time pumped my spill up her to mingle with all that dog spunk she'd received minutes earlier. I admit, I never even thought of if she'd cum off with me fucking her, but she certainly cum off more than once as he fucked her stupid.

Pulling my spunk drooling cock out of her. she just lingered as she was while much of all our cum dribbled from her - The afterglow subsiding she eventually uttered - "Fuck! - What a fucking that was, I'd have never dreamed a dog could do me that good... Did you enjoy watching us, you better had, because you've got me hooked on it and I want more whether you let me or not!" - She stood blatantly in front of my face letting her cunt disgorge dog spunk. - "Pull it open and tell me if he bruised me, fuck I know it was bigger than anything I've had before"

A slight darker blueish area was present just inside where the knot had stretched her, but I told her - "No! - You took it fine!" - After all I didn't want to put her off for the future, did I?

                                       A night at the vets pt. 4 (revised)

A few moments later, his dick was within reach, I put my tongue out and the red tip ran across my outstretched tongue. It sent shivers right back to my over stretched pussy. I opened my mouth and let his penis inside. I felt the damn thing grow inside my partially closed mouth. It kept getting bigger and longer. At that moment, I realized what an idiot I had been. His fur was near my mouth which meant there was nowhere for his foot long dick to go but in my throat. I don’t know ho big he had gotten but my mouth was pretty full. A moment later he started humping my face. At first I was ok, but then he thrusted and I gagged. I relaxed and was ok, but the same thing happened about every few thrusts. This was not being fun anymore. I pushed my head up onto his chest and pushed and he took a few steps back. I was finally ok again and had about 6 inches in my mouth. I was getting face-fucked by the Dane for a few minutes when I felt a weird feeling in my pussy and the next thing I felt was Shepard’s ball coming loose from my pussy. It felt great for a moment, and then there was nothing. I felt like my pussy was wide open. Suddenly I felt the rush of cum pouring down my thing.

The Dane must have smelled it as he started pumping my mouth harder and again I was gagging. I moved my head to the side to get him out a little, but for some reason at the angle I was now at, I wasn’t choking and I could feel him way down my throat. Now I had to concentrate on breathing.

Without notice, I start to fart. But it wasn’t from my butt, it was from my pussy. It must have scared the Dane or something as he backed off me. My legs were still a little frozen and I was able to crawl. The Sheppard was now on the other side of the pen. I was still moving and the pussy farts wouldn’t stop. I started to laugh and was embarrassed. The Dane finally came around my behind to check me out I guess. I was stupid again just for that one moment and didn’t move away from him. That was all it took, he was behind and on top of me.

Just like the first time he mounted me, I felt his wet dick sliding up my butt crack and again hoped he would do just that. Of course he shifted and just like the last time, he hit my butt hole. I figured I better shift and let him get it over with and try not to let him into my pussy too deep if I could help it. His next poke hit my butt hole again, but this time he didn’t retract. He thrust right from there and a few inches went into my ass. I started to scream.

“No, no, you can’t!”

But he could care less and I felt my butt tear a little as he started to pump me. More and more of him entered my dark hole and I tried to drop to my belly, but somehow that hurt where he was hitting inside me as I was dropping and quickly moved back up. I felt more and more of him enter my ass and then just started pounding me. After a couple of minutes of crying and screaming, something weird happened. I start to pant, but it wasn’t from crying. I couldn’t figure it out. I was getting horny again. I was starting to like the feeling. 

“How could this be possible?” I asked myself

I never thought about anal sex as getting a girl off, just the guy. But I was feeling better and better, and for some reason, without my pussy even being touched, I was heading for about my fifteenth climax. As I started to get more excited, I felt him going in even further, the lube from his dick sprinkling kept my hole wet and feeling good. I sure wasn’t worried about his ball going inside my tight hole, but I was amazed when I felt it hit my hole. I ducked my head down to see how far up his shaft the ball had gone and gasped when I saw it hadn’t gone up yet. I had his entire dick inside me. I guess the thought of that was all it took and I started to cum. It was different from cumming from my pussy or clit, it was actually more intense and I almost started to howl. I heard myself and stopped for a moment in fear that with all this dog sperm in me that I was becoming one.

My fear soon ended and my climax continued as the Dane’s huge dick kept pumping my virgin ass. A few minutes later, the ball was hitting my hole and he retracted a bit when that was happening. I was still cumming like crazy when I felt his load fill my ass. He was still pumping and all the cum made it feel even better and I got off one last climax before he pulled his long pole out of me.

Again I could not stand and I wondered if I would ever be able to walk again. I moved along the floor on all fours and went over to the big Dane. He was cleaning off his dick, but a few moments later he stopped. I lay down next to him and put my head on his chest and fell asleep.

Upon waking up again, I notice it is still dark outside the cage, though it must be close to morning by now. My hands and knees felt numb, but in hindsight, it lessened the pain of crawling on all fours as I did. Strangely, I didn’t mind this position anymore and even found it pleasant, in fact, more natural. Looking out of the links of the cage, I crane my head back and forth as far as the locked door would allow. The hall was still dark, but there was a glow clock mounted on the far side. Squinting my eyes, I found they too could see better in the dark and I could make out the hands and numbers. It read 4:30a.m. and was steadily still ticking along it’s course. 

My restlessness must have attracted the attention of the males, for they got up and started moving about me, the Dane sniffing my body all over. The smaller Sheppard busied himself with licking up the caked cum from the night before, his rough tongue passing over my pussy and clit with slow strokes. I trembled under their attention and did the only thing to protect myself. I crouched to the floor in hopes they would leave me alone. Not to be deterred from me, the Dane nudged his nose between my legs and rubbed the cold tip against my clit. Stunned, and a little turned on, I instinctively raised my hips and he began licking me, pushing the Sheppard away. Moaning now under the Dane, I reached out and stroked the Sheppard t full hardness once more, then pulled him close and took his tool deep in my throat. This I was rapidly finding was very pleasing, and I gave myself over to the sensations.

The Dane stopped licking me, initiating a small whimper from my throat. I couldn’t begin to understand it, yet it seemed I had become attuned to him in some basic way. Growling slightly, the Sheppard also moved to my backside and mounted me. His cock, deep red and swelled fully, thrusted a few times before finding it’s mark into my pussy. He again closed his mouth over my hair and pulled tight as if I was his bitch. Not one to be left hanging, the great Dane came up in front of me, his cock engorged and hanging low. I didn’t have a choice, or rather I did but chose the best option, taking his massive pole into my mouth, then down my throat. Both the dogs continued this with me, till I felt their knots enter from either side and fill me with cum. After they got off me, I lay there panting, ignoring that it had gotten light during our exercise.

All of a sudden I hear voices, yet none come towards the kennels yet. During this flood of sound, the Sheppard took his cue to lick my cunt again, covering my body in doggy cum and saliva. I moved away from him and sat on my butt, waiting to see who would be the first to see me in here. It wasn’t long before I had what I wanted, though not the way I expected, and was mildly shocked at what happened next.

The door opened and in stepped the vet assistant along with my mother, her face a mask of worry and concern. They stood talking for a few minutes, and I couldn’t hear a word. Just then, the big Dane got behind me and much to my confusion yet delight, pounded into my well fucked pussy. My moans must have given me away, for the assistant paled and followed my confused mother into the kennels. They stopped in front of my cage and my mother screamed in horror and shock, then turned on the man

“You knew she was here and didn’t tell me?!”

“Well…uh…”

“Get her out of there, now!”

“Eh…yes of course!”

The assistant produced a set of keys and began fumbling for the right one to the lock of my cage. Meanwhile, the Dane was having a blast, pounding into my body. I had to admit, it felt really good now and I didn’t know if I wanted it to end. My choice was stripped however as the assistant found the right key, then unlocked it. Mother immediately reached in and pulled me out. Hugging me tightly, she cried in relief at having me back safe, if not sound. Who would be after getting fucked non-stop by two male dogs? 

Raising my head, I smiled and I swear my rear end wagged as I did, which confused me. I was a human girl, and yet I was acting like a dog. Looking over at the assistant, I lifted my lips from my teeth and growled. He paled farther at realizing what had become of me, even if I didn’t. Mother also looked confused, then shook her head and grabbed my clothes, handing them to me. I stared at them for a moment, then reached out to dress, suddenly finding them repulsive. Backing away, I sat like most female dogs would do and merely waited. Concerned even more, my mom pushed my clothes at me, and I turned my head away.

“Uh…um…perhaps she doesn’t like them?” suggested the assistant.

“What are you talking about? Of course she likes clothes. She’s a girl.” clipped my mom.

On a sudden idea, the vet assistant produced a collar and leash, then dropped them to the floor. My body acted instinctively as my mind screamed for me to stop. Reaching the items, I wagged my butt again in a dog imitation of a tail, then picked both up in my mouth and dropped them in my mom’s lap.

“Sweety no. You’re a human girl, so put your clothes on” she said gently.

Again the favorite, yet offending items were thrust towards me, and again I turned away from them. Nudging the pet items, I sat and smiled at her, not blinking very much as my eyes had adjusted over the night. My mom sighed and sat back as if considering what to do, then glared up at the assistant.

“You should have gotten her out sooner! Now look at my daughter! She thinks she’s a dog!”

“I…I am trully sorry Miss…” he stammered.

Taking a deep breath, mom lifted the collar and leash, then looked at me closely. Her entire posture demanded to know if I really wanted this. Smiling again, I wagged my ass and let out a small whimper, nuzzling her hands and the held items. She got the message and stowed my clothes into her bag, then clipped the collar around my neck. Next she attached the leash to the lead ring and stood, looking down at me with a frown. I cowered a little, lowering my head, but this seemed to upset her more.

“When we get home, I’ll have a psychiatrist help you out of this state sweety”

Ignoring her words, I simply followed as she led me naked out into the waiting room, much to the shock of those sitting there with sick or injured pets. No one said anything though as we exited the building and headed toward the car. Opening the door for me, she unclipped my leash and I jumped into the seat. A little tricky, but I managed it. Once in, we drove off for home, my head out the window.

More to cum later! Maybe. ^.^  This has been my first post, and I touched up the last part of a night at the Vet. I hope you enjoy it!
