Beastiality 08 – A Trip to the Vet’s Office, Part 3

The anticipation was getting intense.

This whole process had started with Mistress’ obsession with having me service her dog, Buster.

But I had not seen her dog since our visit to the vet’s office (see part 1). I had no idea where he was during this time. I did not know if I wanted to bring up the subject her Great Dane, since I was not certain I really wanted to remind her about him. He was a huge dog, and probably weighed more than I did. I had to imagine that his cock was proportionate to his size, and the thought of that penetrating me gave me the shivers.

When I would get up the courage to ask her about his whereabouts, she would just smile and reply, “Do not worry, pet. You will be seeing him soon enough.”

Meanwhile, she worked with me, getting me to obey the hand signals and verbal commands that Miss Allen had taught her (see part 2). To those basic commands of sit, watch me, stand, stay, come, down, fetch, and heel, she added a few of her own. For the command ‘roll over’ she would twirl her finger, and I was to drop to the floor and roll. The command ‘play dead’ was accompanied by both of her hands turning palm down. My response was to lay myself onto my back with my arms folded so my hands were in front of my shoulders. I did not mind this pose at all, because Mistress would often scratch my tummy when I did this. Well, to be honest, she often scratched a bit lower than my tummy, her fingers scratching gently over my mound and pussy making me moan ecstatically, much to her amusement.

The strangest new command was ‘hump’ whereupon she would rub her thumb and middle finger together as the hand signal. To obey this command, I had to straddle her foot and press my breasts against her knee, wrapping my arms around her leg. Looking up into her face, I would begin rubbing my cunt against the bottom of her leg and the top of her foot. Soon her shoe or boot would be slick with my juices, and buffed gleaming by my actions. When she finally petted my head, it was my signal to stop humping, and drop down and lick her footwear clean.

One day, the doorbell rang.

“See who that is, pet,” I was told.

It was a rare occasion in our household – I was dressed.

I opened the door.

Miss Allen stood there, dressed much as before, in a form fitting leather garment, this time with a lot of cleavage showing. She grinned at me, and asked, “How is our little bitch doing?” The tone of her voice indicated that she was not talking to me as a person. Her tonal qualities were those that she might use in speaking to a dumb animal, relying on that animal to perceive her mood rather than actually understanding what she was saying.

Upon hearing her voice, my knees buckled. I dropped to my hands and my knees, looking up at her, smiling, my body taking on a sort of fawning posture instinctively. It was all I could do to stop myself from wagging my ass at the sight of her. As an air current drifted in through the open door, I inhaled a strong scent of dog, which seemed to be coming from her clothing.

She reached out and petted my head, cooing, “That’s a good girl. Take me to your Mistress, girl.”

Even though I was fully clothed, I turned and started crawling toward Mistress, acutely aware of Miss Allen following me, observing my behavior. In hindsight, I suppose that might have been a ridiculous thing to do, but given Miss Allen’s voice, scent, body language – in short, her aura of dominance – I obeyed without thinking.

Mistress was not surprised at the arrival of our visitor. Greeting her warmly, she then turned to me and instructed, “Go to your room and transform, bitch. Be quick about it, and hurry back here.”

I rushed to my room, undressed, and inserted my butt plug with the tail. My collar with its dog tag was already around my neck. Crawling humbly, I returned to the living room.

Miss Allen had Mistress put me through my paces, watching both of us closely. She corrected Mistress once or twice, showing her how to make her hand gestures crisper and more visible to me. She made some miniscule corrections to my positions. She laughed when she saw the new tricks that I’d been taught, even deigning to rub me briefly while I was playing dead.

Mistress and Miss Allen turned their back to me while Mistress whispered something to her. Miss Allen nodded her understanding and crossed the room to sit in a chair. I was astonished when Miss Allen then gave the ‘hump’ hand signal! My face and cheeks felt very hot as I crawled to her, and began humping her foot. The heady aroma of leather and dog wafted around me as I anointed her boot. When her hand touched my head, I scooted back and gratefully licked her boot until it shone.

Miss Allen declared, “You have a very good, obedient bitch here. I think she is ready. Anticipating this, I brought Buster along with me. He is patiently waiting in my van. Leash your bitch, and have her sit at your feet.”

I heard her say ‘Buster’ and my mind went into a spin. I knew what she was talking about. The moment that I both longed for and yet at the same time dreaded was rushing upon me. I was in such a tizzy that I barely noticed Mistress clipping a leash to my collar. My body must have automatically gone into the sit position. I was forcing myself to take slow deep breaths of air so that I would not faint, as my lungs tried to keep up with the rush of blood surging out of my rapidly accelerating heart. I was sitting stock still, staring at the door. I was not looking down at my own body, but I could swear that my heart was jumping so hard in my chest that it was making my tits bounce.

The door swung silently open and Miss Allen brought in Buster. I gulped. He was even bigger than I remembered. He was heeling perfectly, placidly staying beside Miss Allen as she walked him to stand in front of us. He held his head up proudly as he walked. As I got a brief side view of him, I saw how in profile his torso swept from his large chest back to his comparatively narrow and delicate hips. Just in front of his hips I could perceive the furry stub housing his penis.

“Have her stand,” she instructed Mistress, nodding at me.

“Stand,” Mistress said, using the ‘up’ hand signal. I rose to stand on my hands and knees.

“Walk her forward about 5 feet,” Miss Allen commanded.

My body obediently followed Mistress’ lead as we moved forward.

“Have your bitch stand perfectly still. This introduction is quite important,” Miss Allen cautioned.

Taking no chances, Mistress knelt before me, and held my face in both hands, making a soothing sound in her throat. I trembled in her hands, wondering what was going on behind me.

Miss Allen brought Buster close enough that he could sniff my ass, as dogs do during a meeting. I felt his whiskers brush my ass cheeks. I heard the sniffing sounds, and felt the wind from his nostrils as he snorted after inhaling.

“You can let go of her head. It’s her turn now,” Miss Allen indicated. Mistress released me, and stood to one side, holding my leash.

Miss Allen maneuvered Buster so that his butt was practically in my face. “Go ahead, bitch. Sniff him. He expects it. You don’t want to refuse his offer,” she almost chided.

I brought my nose closer, sniffing delicately, worried it might be gross. To my surprise, he just smelled like a clean, healthy dog. I inhaled most robustly, and, after a moments thought, snorted air onto his ass as well. Protocol was satisfied.

I could not help but notice the huge ball sack that hung below his ass hole. His testicles bobbed and swayed with his movements as Miss Allen walked him away from me.

Miss Allen asked,“Where is Buster’s favorite part of your home? Where does he usually rest when not doing anything in particular?”

“Over in this corner of the main room,” Mistress replied, indicating with a sweep of her hand.

“Excellent. That is his domain, then. He will be most comfortable and secure if we start with him there.” So saying, she walked him over to the spot indicated.

“OK. Bring your bitch about 4 feet in front of him, and have her present her hindquarters. Normally, she would hold her tail to one side, to indicate her readiness, but since she has no muscular control of that ‘tail’ you will have to hold it out of the way.”

Mistress moved me into position, and grasped my tail, pulling it to one side, exposing my sex to Buster.

I looked back over my shoulder, wanting to see his reaction. As far as I could tell, he was looking at me with polite attention, but making no other movement, other than to occasionally glance up at Miss Allen, as if asking for commands.

“Open your cunt lips, bitch, and rub yourself. He needs to get your scent. He needs to know you are in heat, and offering yourself,” she directed me.

Blushing slightly at being told to display myself so wantonly, I nonetheless reached between my thighs. My fingers found the petal edges of my pussy lips, and I pressed them wide apart. I started sliding my fingers through the furrow between them, feeling the sensitive skin there prickle into life. As I continued toying with my clit, peehole, and vaginal opening, the glands within my intimate tunnel sprang into action. Fluids began welling up, ultimately reaching open air and starting to drip onto my hand. I smeared them all over my labia, and continued stroking myself. My submissive energies also took hold of me, and I even swayed my hips enticingly as I played, as if summoning a lover to come and sample my wares.

I lowered my head and shoulders until my torso rested on my tits, and became acutely aware of my scent, now wafting freely from my wide open, oozing cunt. Since dogs have a magnificent sense of smell, compared to humans, I was sure Buster was getting a snout-full. I heard him whine, and twisted my upper torso sideways enough to peer down my body to where he sat. He whined again, his eyes fixed on my cunt, and I saw his long pink tongue slip from his mouth and travel the length of his lips.

“You want to lick her, boy?” Miss Allen asked encouragingly. “You want to taste your little bitch?”

Buster barked once in assent, his forceful voice filling the room.

“OK, bitch. Stop playing with yourself. He understands your invitation. Keep your ass up high, your thighs wide apart.” She had not told me to come back up onto my hands, so I remained with my breasts pressed against the floor, hands stretched out in front of me. Heart hammering fast in my chest, I heard Miss Allen lead Buster toward me.

I waited an eternity.

Actually, it was only seconds later that I felt his hot, wet tongue rasp up across my wide open sex. I almost shrieked, because it felt so good! He was not dainty, or delicate. He licked me fast, letting his tongue gather my fluids like he was lapping water from his bowl. Once he had cleaned what he could find on the surface, he began darting his tongue into my vagina – the source of this treat. I felt that tongue not only plunge to my depths – I could swear I felt its tip curl up in a scooping action as it dragged copious amounts of fluid from my most intimate reaches.

Once or twice his tongue touched something so sensitive that I moaned loudly, barely able to keep my body from jerking. His tongue tip had flipped over the moist knob of my cervix! I may have imagined it, but it seemed that his tongue lashing accelerated when he heard the sound of my moan. His tongue slipped out of me and again began washing the entire surface of my privates, from my clit all the way up across my ass hole. My body began shuddering in orgasm, my cunt making a strange sucking sound as the muscles of my vaginal wall rippled. Perhaps drawn by that sound, his tongue speared into me once again as he feasted on my fresh flow of rich juices. I was glad that my upper body was fully pressed to the floor. Otherwise, the force of my orgasm might have knocked me over.

Miss Allen addressed Mistress. “See? Even though he has never done this before, his instincts are taking over.”

I turned my head to look over my shoulder, trying to focus through the curtain of bliss that I was still experiencing. I saw Mistress peering intently in the direction Miss Allen was pointing.

“Oh yes!” she exclaimed. “His cock is beginning to emerge from its sheath! This is so exciting!”

After licking me a few more minutes, Buster finally stopped and began whining.

“I think he’s ready,” Miss Allen stated. “Now, since he’s never done this before, you and I will have to help him. Have your bitch hold her own tail out of the way. You will need both hands free.”

Mistress took the tip of the tail that emerged from the butt plug, and tucked it under my elbow.

“Lift him by his chest and fore-paw on your side, while I do the same on my side,and help me ease him forward,” Miss Allen commanded. I could feel the presence of Buster looming over me as they drew him carefully forward. Since I was holding my ass up high with my upper torso flat on the floor, my back was arched so much that Buster’s chest did not touch my back as the two women lowered him into place. His fore-paws ended up on the floor on either side of my neck with his front legs pressed against my collarbone. Something wet brushed one of my ass cheeks and then began rhythmically prodding against them.

“As you can see, Buster is having a difficult time finding her hole. The first few times that he mounts his bitch, you need to be prepared to assist him in locating his target,” Miss Allen pointed out. “With practice, his muscle memory will guide him during future breeding sessions.”

I admit I was mentally jolted when I heard the word ‘breeding’ spill from her lips. In both of their minds, I was a bitch – Buster’s bitch – and my purpose was to be bred by him! A wave of humiliation blended with perverse excitement washed over me, causing me to sink into one of the deepest levels of submission that I had ever experienced.

“Watch as I open up the bitch with one hand, and position his cock with the other,” Miss Allen instructed. I felt her fingers part my labia, and a moment later the tip of his cock was at my entrance.

Buster’s hips had been in constant motion this entire time, moving back and forth in a rhythmic humping action. With his next forward movement, his cock began burying itself into my now sopping tunnel. He growled in triumph as he wedged that stiff rod of flesh inward. Lubricated as I was, it was still no easy task, because his cock was bigger than even the largest dildo that Mistress had ever used on me.

I grunted as his first few thrusts stretched my opening. My grunts turned into loud groans as that massive penis burrowed its way farther and farther into my very core, forcing my vaginal walls to give way to this invasion. If I could have crawled forward, I might’ve been able to lessen the impact of his insistent hammering. But, pinned in place as I was by his front legs, I could not move forward – I could only submit.

And fluids. Lots of fluids. I became aware of fluids squishing out of my vaginal opening with each of his humping thrusts. The fluids at first trickled down my thighs, but soon became a fast flowing rivulet cascading down to pool at my knees. Upon seeing this, Mistress asked Miss Allen, “Is he cumming now? Is all that his semen?”

Miss Allen laughed, “Oh no. That is merely his precum!” She scraped her hand up my thigh, gathering a palm-full of the stuff. “Here, bitch. Taste it,” she said. As I opened my mouth, she tilted her hand to pour it past my lips, and also had me lick her palm clean. It was a thin, watery fluid, tasting mostly salty. Returning her focus to Mistress, she continued, “He can produce prodigious amounts of it. Sometime, when you feel like being entertained, have your bitch suck on his cock and watch how much she needs to swallow to keep up with him.”

Suddenly, Buster bounced the front of his torso upwards, bringing his fore-paws down onto my back. “Thank goodness his nails are trimmed,” I thought, as my shoulder blades accepted his weight. His movement also pushed his hips backwards, yanking his cock out of my sorely stretched tunnel. Precum was still spraying from his penis, arcing onto my back and into my hair, and painting a trail across my ass and the back of my thighs as he leapt sideways off of me.

I turned my head to look at him, and gasped. He was standing with his head turned back and his hips brought forward so that his tongue could lap at his exposed cock. I was not gasping at the fact that he could lick his own cock – I was gasping at the size of it! I was amazed that my tiny little cunt had been able to accommodate it. Its mottled red and pink surface glistened with a mixture of precum, saliva and cunt juice. My gaze traveled from its strangely pointed tip all the way back to where it emerged from its furry sheath. I was shocked to see something at its base that was the size of a large orange or a small grapefruit.

I was about to ask what that was. But I did not have to. Miss Allen was already standing near Buster and pointing at it. “This is his knot,” she explained to Mistress. “For a successful breeding, the male pushes this into the bitch’s vaginal opening, sealing it. This ensures that his semen is trapped inside her, and floods inward, directly entering her womb. His sperm then have a much shorter distance to swim in search of eggs. The sperm can live about three days inside the bitch.”

My heart leapt into my throat, forcing me to stop breathing for a moment. The thought of live dog sperm swimming around inside me for three days almost short-circuited my brain activity. What shocked me the most was how this perverted idea ultimately excited me. Unbidden, a low growl formed in my throat, and I saw Buster prick up his ears upon hearing it.

“But is Buster all done already?” I heard Mistress ask with a tone of dismay. “He got off of her so fast!”

“I don’t think he’s done,” Miss Allen assured her. “But I don’t think he was completely satisfied with the way the bitch is positioned for their mating. Try having her stand.”

Mistress moved to where she was certain she had caught my eye. She said, “Stand” as she gave the hand signal for that command. I was still somewhat dazed, and she had to give the command twice before my body finally reacted. Pressing with my elbows and hands, I raised my shoulders up level with my hips, and swiveled my head back to watch Buster’s reaction. He stopped licking himself, and panted quietly as he stared at my new pose. Within moments, he shuffled around behind me.

“Should we help him mount her again?” Mistress inquired.

“Let’s just see what he does on his own this time,” Miss Allen replied. “But hold her tail out of the way, and be prepared to assist his cock in finding her hole.”

Snuffling noisily at my cunt, with his whiskers tickling my butt, Buster inspected his bitch. Satisfied, he reared up and planted his fore-paws squarely on my back. His massive chest covered my back with intimate warmth. His chest fur pressed along my spine, moving as he breathed. Instinctively, I arched my back to conform to his shape against me. Once again I felt his cock prodding and probing. Swiftly, Mistress spread my labia apart. Either she guided him to my opening, or he got lucky with his probing. I felt his cock plunging into me as he claimed me as his bitch.

I was surprised at how good it felt this time as he stuffed me full. Apparently my pussy had adjusted itself to handle his girth. His precum was doing its job of making me slippery for him. Since I was now more upright, I had to brace myself to absorb the power of his hammering thrusts. My pleasure built and built. Never had I felt this well fucked before! It was not long before I cried out, “Yes!” to my doggy lover and began cumming hard, my tummy fluttering as my cunt muscles mixed my cum fluids with his precum.

I was vaguely aware of the two women watching me being used in this manner. It should have been mortifying, I suppose, but in my state of submission it had the opposite effect. It aroused me even more. My body began shuddering with either orgasmic aftershocks, or with a string of miniature releases, one following the other in rapid succession.

While I was in this state, Buster slid his paws off my back, tucking them around my waist, pulling my hips back more firmly into his thrusts. His embrace held me so strongly that I no longer had to brace myself with my hands. But in this position he was able to force his cock even deeper, its tip now occasionally poking my sensitive cervix. Each time contact occurred there, I yelped loudly. This seemed to excite Buster even more. With every yelp, he fucked me harder and faster. I was fairly oblivious to the passage of time at this point, but later Mistress said he fucked me for about 10 minutes like this!

Ultimately, I felt his knot now pressing at my opening. I remembered its size. It seemed impossible that my vaginal entrance could accept it without being torn. But Buster was not to be denied. Four things happened at the same time. My cunt began rippling with yet another orgasm. The thrill of the orgasm caused me to press my cunt more firmly onto his penis. Buster pulled me backward even more firmly with the massive paws he had wrapped around my waist. At the same time, he bucked his own hips forward a fraction more.

I howled as his knot popped past my vaginal ring, and lodged itself firmly in the entrance to my cunt! Buster stopped his earlier humping actions, since any large movements would cause pain to both of us. Instead, he held me in his tight embrace, and I became aware of a curious sensation in my cunt, unlike any I had ever felt before. He was squirting into me!

Miss Allen’s voice whispered in the now quiet room. “Ah! He has now knotted his bitch. You can tell because he is holding still, attached to her. This is when he starts cumming. His semen is now flooding into her. If you look closely at her mound and tummy, you might be able to see them distend somewhat.”

I didn’t know if they could see me swelling down there. But I could sure feel it! His semen kept spurting into me, and it had no place to go but inward! My vagina was quickly filled to bursting, and the fluid pressure forced the dog semen through my cervical opening and into my uterus – my womb! Once that was filled, his cum must have been forced up through my Fallopian tubes. From there, it flowed from their open ends and entered my tummy! I was amazed at how aware I was of the internal progress of this flow. Or maybe my fertile imagination was just visualizing its journey. It was one of the most erotic moments of my life.

Between spurts, Buster would make the tiniest of thrusts, and his cock would again spew another load. He was panting now, his drool and hot breath on the back of my head and neck. To my amazement, I felt him place his teeth at the back of my neck – not hurting me, just… just claiming me as his own! I felt deliciously submissive in this embrace. I was in no hurry for it to end.

That was a good thing, because now Miss Allen explained to Mistress, “While they are knotted, you must not try to separate them, or they may both be injured. Gradually, his knot will subside, and then he will pull free of her on his own. Do not try to rush this.”

“How long will they stay locked together?” Mistress asked.

“It varies, but I would expect the knotting to last about 15 to 20 minutes.”

After perhaps 10 minutes, Buster stirred, released his embrace on my waist, and slid sideways off of me. We both yelped as this action tugged painfully at the tissues that still joined us. He stood now facing away from me, our asses pressed against each other, his cock bent completely backward from his torso and still firmly embedded in my cunt. His tail occasionally brushed over my back as he wagged it. Again I lowered my shoulders to press my tits against the floor, assuming that very submissive posture. The posture of a lowly bitch, who had just received the fucking of her life from her alpha male dog. More time passed as we panted quietly, regaining our breath. My cunt entrance felt rather numb, so I could not tell if his knot was changing size at all. But I guess Buster could, because after a while he started pulling away from me, his feet scrambling on the floor. There was mainly a tugging sensation at this point, followed by a loud squelching sound as his cock finally pulled free.

Eyeing my backside, Mistress exclaimed, “Good grief! Look at her gaping hole! Will it ever be normal again? And all that goo gushing from it! What a mess!”

I felt my cheeks flush red hot with embarrassment, imagining what they both were seeing.

“Well, since you will have her servicing Buster on a regular basis, I doubt that her cunt tunnel will shrink back to the diameter that it was before. But that’s actually a good thing, since they both will experience less pain when they couple. As to the gaping – watch what Buster does now. I expect his instincts will kick in.”

Buster had been lying down on his side, licking himself clean. As he licked the fluids from his cock, it gradually disappeared back into its furry sheath. I watched this process with fascination, and saw him complete it with a thorough washing of his balls. After that, he got back onto his feet, and trotted over to stand behind me. Once again I felt his magical tongue lapping around my vulva. But this time, he did not plunge it into my depths. He concentrated on cleaning my outer surfaces. These mild sensations apparently caused my tissues to contract, easing my gaping hole closed, judging from the muttered comments between Mistress and Miss Allen as they watched. He concluded his performance by using his tongue to press my labia tightly against each other.

“See? It’s as I told you. He instinctively knows to close the bitch’s cunt, helping to keep his semen from seeping out,” Miss Allen explained. “He’s a bright boy. You could probably teach him to mount on command. And now that he has the idea, I suggest that you let him mount your bitch whenever he has the inclination. He may go a day or two between breeding sessions, or he may do several a day.”

I heard the words ‘mount on command’ and ‘several a day’ with mixed emotions. Just this one session had been rather exhausting. Would I have the stamina to handle several in a day? Perhaps my body would adapt, given time. As I focused on my body, I thought I could feel the wriggling tails of millions of dog sperm swimming inside my womb, and shivered with perverse delight.
