The Dog Clinic

Hello, my name is Freya and I work in a Veterinary Clinic in a small village in Holland. My job is to assist the veterinary surgeons in their research work with animals. They deal mainly with dogs and I care for the animals when the clinic closes in the evening and at weekends.

I love all the animals and would do anything for them, but my favourites are the dogs. The current research involves dosing the animals with human genes to try and help with human reproductive problems. What this means, in reality, is that they are using the dogs to substitute for humans by giving them hormones and gene therapy to make their bodies emulate human bodies. It's much easier to get a licence to experiment on animals rather than humans. One of the research experts explained that the male dogs are now capable of fertilising a human egg and the female bitches are capable of conceiving and bearing human babies after they have gone through the program to 'culture' them. They are soon to try and create the first baby to be born to a female dog in the whole world, although the scientist who confided in me said they have already proved it works in the kennels and aborted the foetus after 4 months due to ethical problems.

Apart from my real love of animals, I have another reason why I devote my life to them... I have sex with the male dogs and would do this job for nothing just to enjoy the orgasms they give me.

I find that the best time to have good sex with my dogs is dependent on my menstrual cycle. The odour from my vagina always excites the male dogs, I suppose it reminds them of the smell of a bitch. If I'm having a period my vagina gives out an especially strong odour and the male dogs see that as a signal to fuck me. When a dog bitch is in heat her genitals become blood-filled, swollen and give out a higher amount of odour. The bitch will then, when given a chance, turn her back to the dog, to show the dog that she is ready to be mounted. The male dog will then often sniff at her vagina and lick at it for some time. After some time he will mount her. This procedure works the same with women. When a dog smells my scent he will approach me and start to sniff, after that he will try to lick me.

I always get a large dog with a good size penis as a thick penis provides more friction on my clitoris. I love the bone that a dog's penis has running through it. When it hits my clit or my cervix it never fails to excite me. Because when it comes to dogs, the size of the penis is irrelevant compared to the way it's built. A dog's penis looks completely different when compared to a humans. Instead of having a foreskin like the human, its entire shape is like the tip of the human male, that means reddish, and very sensitive to touches. The lack of foreskin, means instead that they have a 'coat' in which the entire penis withdraws when it's not erected. This coat is furry, and hides the penis which is much larger than the sheath is, and when erected it draws back, and allows the penis to push out and enlarge. Instead of having the familiar and sensitive 'mushroom', like the human, it is pointy at the tip, then growing larger after 2-3 cm. The entire penis is as sensitive as the human's tip. When a dog gets aroused his penis erects and leaves the protective sheath. Unlike a human the dog creates the sperm while his penis is erected, and he is aroused. Another thing that differs is that the dog's penis will ejaculate during the entire sex act, from the first moments of erection to the end of the intercourse, this makes the intercourse more pleasurable. But the most important feature, is the one that makes the sex act most exciting, the dog's KNOT... When a dog enters the bitch and starts his humping motion in her vagina, he also starts coming instantly. But after some time, when the male dog reaches 'real orgasm' then the base of his penis will swell. The male dog will then try to push this knot inside the bitch's vagina. Once inside he will not move any longer, instead he will keep a constant pressure to assure that the knot is really inside. During these seconds the knot will start swelling even more inside the vagina to such a size that it won't be able to extract. During this time the dog will start to ejaculate even more intensely inside the vagina. The knot's function will then be to keep the mating couple together for some time. The reason is to ensure that the sperm is deposited deep inside the vagina and to increase the chance for insemination. Many women only have sex with dogs because of this feature.

Making love to a dog can be very simple, as they are always ready for you. However I have these items handy when the itch starts, just to make my pleasure even greater and to make it good and safe for me. I put socks, on my lover's paws to prevent them from scratching me. But, most importantly, with these dogs, I wear my Contraceptive cap and spermicide, to prevent inadvertent pregnancy!

The dog starts coming almost instantly when his penis erects. At the beginning the spurts are very slow and the amount of liquid is very small, but the more aroused he gets the more liquid will he produce. When I'm prepared to let him enter me, I find it's wise to have a big towel under me so that his semen wont stain the carpet or sheets. I should add that these dog's sperm CAN get you pregnant! Therefore I take my usual precautions to prevent that problem. I can't take the Pill so I have to use a contraceptive cap which I fill with spermicide and have to leave in position for at least 6 hours after love making has finished.

There are several positions in which I can make love to my dogs. Each position has an advantage, but it's good if you know something about all positions, that is which one gives the most pleasure, which one is where the penis enters you the deepest, or which one where my clitoris is mostly stimulated and the most important, in which position I am likely to end up in a 'tie' with the dog.

The missionary position is probably the most used position through time. In the missionary position the woman lies on her back and the man is above. The missionary position can also be used when making love to a dog, it gives the woman a chance to supervise the entire session and to see the entire process. The missionary position can be performed in bed or on the floor. If the dog is a big one, it's good if you have 1 or more pillows, the big 'hard' model is preferable, which can be placed under my body. By placing them under my buttocks, the lower part of my body will be in such an angle that the penis can be inserted easily into my vagina. When in position you guide my lover's penis, to make it easier for him to enter you, and when he is inside you I just try to relax. The lubricating semen of his will make it extremely easy, and within a few seconds he will start to make the so familiar 'humping' motions. What is interesting and enjoyable is that the rhythm is pretty fast and the session is very wet. During the entire session the dog will come inside me, lubricating the walls of my vagina. But when a dog approaches 'real' orgasm his penis will start to swell even more, especially the base of his erection. This is the moment to decide whether I should let him get in a tie with me or not. If I don't want to then I try to push him away by grabbing gently around the base of his penis, however it's the tie that makes it extremely pleasurable, and by not engaging in a tie with my lover, I wont get the ultimate feeling. If I let him keep humping me his penis will swell even more, and suddenly he will stop with his entire shaft inside me, and at the same time I feel the warm semen spurting inside me, his penis pulsing. The amount of semen in each jet increases, and the watery and transparent appearance of it is changed into a more whitish liquid which reminds me of human sperm. In a few seconds his penis reaches such a size that the base of it will be up to 3 times the diameter. The base of the penis that has swollen to such a size is located just inside my vagina. The knot will be in my vagina and I feel my body is completely filled. A dog's body temperature is very much higher than a human's, therefore I can feel the heat of his warm seed spurting deep inside my me, and due to the pressure caused by his enlarged penis, it will soon spread in my entire abdomen. The knot means that nothing will leak out. After a minute or two I will feel his penis swell even more, and I sometimes panic at some point when I think that he will swell to such a size he will split my vagina. The enlargement comes slowly and the vagina accommodates to the size easily.

During the tie the dog might start to lick my face, the reason a dog does this is to show his appreciation, to his mate that he has been chosen to make her pregnant. What I have to check before I end up in a tie is that I don't really know how long I will be in a tie with the dog. 'Normal' time for being in a tie is about 5-15 minutes. However it's not unusual to find dogs which end up in a tie for 30-45 minutes, especially the bigger dogs. I can give you an example, with a lover I have been in a tie for about 4-5 minutes which is the shortest, but with the same dog I have been in a tie for over one hour. Therefore I have to be calm and have more free time than I would when making love to a man. This is the main difference in the sex act between a man and a dog. A dog wont leave you after he comes, instead he will remain hard inside you, coming all the time he is in you. It's important that I don't have to suddenly go to the kitchen to take something out of the oven or similar. When the knot has swollen in such a size it reaches it's maximum my vagina will probably be full of his seed, as a dog produces about 2-6 times the amount of sperm a man does. The missionary position gives me maximum clitoral stimulation. But I also get stimulation of my clitoris and breasts by his fur, and it feels extremely exciting having his humping body in contact with my naked skin. When the knot is just inside my vaginal opening my labia will pout out, making the clitoris protrude from between my vaginal lips. This gives me an excellent chance to masturbate. It often doesn't take more than a few touches due to the fact his knot is pulsing inside me, stimulating the clitoris from inside to induce multiple orgasm. My body will be flooded by orgasm after orgasm, my vagina twitching and squeezing my lover's penis uncontrollably for several minutes. During the later part of the tie I will feel my lover's penis start to get smaller, and I will also feel that his spurts aren't as powerful as earlier. The liquid will also consist of less sperm and a more clinging substance. The Scientists explained that the reason for this is to 'close' the entrance to the womb, to create something like a plug to hold the sperm that has entered inside it. This plug has the function of assuring that a high amount of the dog's sperm will remain inside the womb and to make a pregnancy possible. However, because I could become pregnant, I have to rely on the latex rubber of my Cap to prevent semen from entering my womb. I had once decided to try anal sex with a dog and for this reason I had left my Cap out, feeling that even with my anus full of dog sperm, I would be safe. However, as it turned out, the animal I had sex with that night appeared to know what was what on a woman, and no matter how many times I adjusted my position to take him anally, he pulled back and came forward again to try and take me vaginally. In the end I had to return him frustrated to his kennel, as he would not follow my plans for sex that evening,

I think it was because of that night that I tried a more risky form of sex with my dog. I don't know what got into me that day, it was a Saturday and I was alone in the Clinic. I had taken Major, a large Great Dane for an extended walk and I took him back to my room. As I reached for my Cap and the can of spermicide I suddenly had the urge to ride bareback! Putting the Cap down on my bedside table I adopted the 'doggie' position but 'chickened out' when I saw the dog's erection develop. I could see pre-come leaking from the tip of his penis already and I knew it was dangerous. However, the urge wouldn't go away so I compromised and put on a pair of panties to protect myself. Bending over the bed again I watched Major approach me. Shaking with anticipation I saw his erection build again and he ran forward to take me. He began humping at my pantie covered backside and his pre-come stained the material. I knew I wouldn't be satisfied without full penetration and in a moment of madness I reached back and moved the gusset slowly to one side. My heart was pounding as he tried to connect with my unprotected sex organ. Then he connected and penetrated my first inch. I panicked and tried to back out of the whole thing but his next two humps forced his all eight inches of his penis fully inside me and the weight of him pushed me down on the bed. It was as if he knew I was capable of conceiving and he seemed determined to 'do' me! All I could do now was wait until he ejaculated and pray that it was the wrong time of the month for me. In the corner of my eye I saw my contraceptive Cap on the bedside table. It was useless now as the dog come almost immediately and I felt him thrusting the contents of his testicles deep inside my womb. He quickly slipped his knot inside me and rapidly expanded it to complete my treatment! I was tied to him for a full hour and as he licked my neck and the side of my face he almost appearing to be gloating at his conquest. I got lucky that time as I started a period two days later. To teach him a lesson I forced him to lick my period blood and baited him for failing to impregnate me. The trouble is that I was left with the urge to have risky sex with these dogs and I decided to keep a cutting from an advert from an abortion clinic in case I weakened and a dog managed to fertilise me.

It can be very stimulating to feel a dog's penis in my mouth, to see it so close, to feel his seed spurt. One day I know I'm not going to be able to resist the urge to take a dog's knot in my mouth. It's desperately dangerous as the erection will be down my throat and the knot will be trapped in my mouth. It will definitely prevent me from breathing through my mouth and it will leave only my nose to breath with. I may have to breath this way for up to an hour if the dog's knot persists.

The scientists have also managed to isolate the canine pheromone which causes a bitch to go on heat. I stole a syringe of this fluid last week and sprayed my knickers with half of it one evening after hours. The effect was staggering... Every male dog in the place was affected. Wherever I walked the dogs developed erections in their cages and clawed at the wire to get free and at me! The sensation of power was overwhelming as I strutted through the kennels causing mayhem!

Unable to resist the feelings any more I let myself into a cage with three German Shepherds in it. Instantly I was faced with three huge erections as they sniffed voraciously at my crotch. I was soaking wet with the effect it was having and all the dogs' attentions. They all but forced me to my knees and I hastily let myself out of the cage and returned to my room. I couldn't risk being gang raped by three dogs that were capable of inseminating a woman. Back in my room I frigged my fanny to orgasm, but still I was not satisfied. I knew I would weaken and so it turned out. Fitting my Cap I went back to the kennels and immediately they caught the smell the sleeping dogs awoke. That stuff was incredible! I let myself into an empty cage that was linked to a cage with the three Alsations. I got down on my knees with my backside towards them and watched as they clawed and the wire between the caged in a frenzy! I looked wistfully at the latch locking the gate between the cages and then in a moment of madness I reached up and opened the gate just enough to let one of the dogs in. It was all I could do to stop all three from forcing their way into the cage with me. Snapping the gate shut the lucky dog that had got in mounted me instantly and his leaking penis soon found its way to my sex lips. I was facing the other dogs through the wire as their partner fucked me mercifully, coming in me continuously. The outside dogs licked their lips and howling in anticipation of gang raping their 'bitch'! I knew that after this dog had done with me that I wouldn't be able to resist letting the other two in to fight over me. All the dogs wanted to have me that night. The current dog formed his knot in me and the others calmed down seeming to know that I was temporarily 'out of action' Taking my chance I undid the catch on the gate and they rushed to sniff and lick me. Two huge alsations waited for me to become free to fuck again. I was their bitch and they were now in control! As the first dog's erection wilted and he slid out of me the other two fought and snarled to be next. I shut my eyes and waited for the victor to take me. I didn't have to wait long as the black and brown male connected with me and pushed viciously into my slit. The greasy liquid from the last tenant helped his penetration and he humped liked the end of the world was due. He was a large dog and I felt him touch my cervix with the spurting tip of his bony penis. A wave of panic swept over me again as I feared that the latex rubber might not hold out. My period was two weeks ago and I was definitely due to ovulate. His semen joined the rest and the knot formed within me. I took the opportunity to frig my swollen clitoris to a massive orgasm whilst the third dog stood behind me as if in a queue. Ten minutes later he was inside me and supplying another huge dose of dog semen. It ran down my inner thighs like milk!

Crawling to the gate , I somehow managed to get out of the cage and lock the dogs in. I lay gasping for breath as I felt my battered crotch. Three frantic dogs had taken me and didn't I know it. Back in my room I lay on the bed and felt my slit. There was at least a pint of semen inside me and I knew my Cap would have to stay in place for all of the next day. As I drifted off to sleep, however, I felt that urge to take the dogs bareback returning...

The following month, I checked my diary. Ovulation was imminent and the urge to take a dog bareback was beginning to overwhelm me. I fished out the advert for the abortion clinic and rang the number. I asked how much it cost and how soon I could be done. The receptionist told me that it was 300 guilders and there was a two week waiting list. I checked my bank account and finding I could afford it, made my mind up. The dogs were going to enjoy this evening! I booked a two week break from work, a month from now, just in case I 'took' and waited until the last member of staff left. I then I put on a black waspy and stockings leaving my backside exposed. The dogs would require full access to my lower appendages! Shaking with anticipation, I kept asking myself if I would go through with it or 'chicken out' at the last moment. Looking for ways to delay my visit to the kennels, I sat on the toilet and urinated nervously. Then I wiped my sex lips and reached for the half syringe of dog pheromone... I squirted a generous amount of the wonderful dog juice on my vulva and then I was ready... I knew that when the dogs smelt me, they would be as well! Slipping on an outrageous pair of high heeled shoes I strutted down to the kennels with my fanny and backside exposed to the cool air.

Walking slowly down the corridor between the cages, the wailing and howling started. The feeling of power was immense! Which dog was I going to select to try and impregnate me? I took my time savouring the occasion and walked backwards and forwards twice. I had intended to give Major another chance to 'do' me, but before I reached his cage, I passed the cage of Nero. Nero was a vicious Rottweiller, one of the biggest dog in the kennels. I had seen him mating with a bitch, and it was the most violent lovemaking I have ever witnessed. He had fucked her legless! I stood outside his cage and paused. Would I go through with it, could I accommodate such a huge animal? I reached down between my legs and felt myself. I was soaking wet and oozing lubrication fluid. As he stood on his hind legs with his front paws on the cage fence, I could see his large dark red erection already hanging from its furry sheath. It was long and tapered off at the end like a spear. A drop of pre-come hung from the tip. I managed to collect the liquid by slipping my arm through the wire. I tasted it and noted its familiar 'iron' like flavour. My arm raised to undo the catch. Apprehensively, I lifted it but replaced it again without opening the door. I couldn't do it. I stood and looked through the wire. Nero could smell my greasy fanny and I knew he wanted to dump his spunk deep inside me. Half of me wanted him to do just that and half of me was too frightened to got through with it. Just then, I noticed the security camera mounted on the corner of the kennel entrance. It was pointing straight at me. I knew that the video recorder was not turned on at present, but a sudden idea came to me. Not only could I let this dog fuck me to a fat belly, but I could also record the occasion. I hurried back to the control room and locked the camera on Nero's cage. Then I put a blank 3 hour tape in the recorder and turned it on.

Back at the kennels, I noticed the cage next to Nero was vacant and I opened the door and locked myself inside. I looked at the door separating me from the dog's cage. One small latch was all that stopped this massive dog from getting at me. I got down on all fours and turned my bottom to point at his face like a bitch on heat would do. His erection dropped completely from its sheath and leaked more pre-come. It must of measured a full 9 inches and tapered from the point to a swelling at the rear which I knew would expand and trap me for hours. His face pressed against the wire trying to lick my slit. I shuffled backwards to meet him and his tongue sliced across my backside. My whole body twitched in pleasure. I knew, now, that I couldn't stop myself. I reached for a yard broom leaning against the fence and put the handle under the latch. One small push was all that was needed to free the gate. One small push and I would be committed... I put my head down, shut my eyes and pushed...The door sprung open and the dog bounded into the cage so fast that he slipped before he could turn and get to me. A 180 LB dog with a nine inch erection mounted me immediately, growling and snarling as he did. His bitch had presented herself and he was going to fuck her violently. I panicked and tried to change my mind and get up, but he reared up, his hot breath right next to my face. He bore down on me forcing me to put my head on my folded arms. Struggling uselessly, I waited. His penis lodged in the crack between my arse cheeks and he manoeuvred it skilfully down to his prize... the bony tip of his erection engaged after a few tentative nudges and I gave up the unequal struggle as my penetration began. I recalled the voice of the abortion receptionist saying there was a two week waiting list. Would I need to call her soon? The violent thrusting of Nero's cock made my breasts swing wildly and they came out over the top of my waspy. I gasped and squealed as he totally penetrated me in the first 5 or 6 thrusts. Several of the dogs were 'witnessing' my treatment through the wire of their cages. The weight of the animal prevented any chance of escape. It felt like I had a tree trunk up my vagina. I waited for the inevitable. Nero's huge weapon seemed to be like a fat finger trying to enter my womb. The bone which ran through the middle of his penis searched for my reproductive opening and I felt it probing the entrance to my uterus. Slowly and expertly he delayed his ejaculation until he forced his way into my cervix. I felt it dilate as he demanded it to open, ready for his delivery. Then it came...he suddenly slowed his thrusting and I knew his ejaculation was imminent. The tip of his penis slid into my womb like a hypodermic syringe and with his hot breath panting on my face I heard myself stupidly pleading with him not to come in me. But dogs don't understand all that well and I knew that my fertile womb was about to play host to 40 billion dog sperm and I was powerless to prevent it. I actually felt the first squirt hit the back of my womb like a slap followed my several other spurts. As he thrusted he injected my unprotected womb with a quarter of a pint of semen. I waited, frightened to move as his thrusting subsided, and then amazingly, Nero gently bit the back of my neck and I actually felt my ovary realise an egg! His sperm began to swim up my fallopian tubes in search of their goal. His massive knot formed to lock me to his body. My vagina was sealed and so was my fate. I reached one arm down to my clitoris and was staggered to feel it hanging outside my body as if on a stalk! I wasn't going to waste this opportunity and I frigged my clit to an earth shattering orgasm which racked my body as it sucked hungrily at his dick. Still 'tied' an hour later, I started to think when the moment of conception would be. Or had it already happened? The voice of the abortion receptionist came back. " Do you want me to book you in?"

At last he relaxed and his weapon finally slid out of my body, he started his licking of my crack to try and seal my womb entrance. I dragged my exhausted body to my feet and ushered the dog back into his cage and tottered back to my room. Slumping back on the bed, I tried to recover from the ordeal. I had just been fucked senseless by an adult Rottweiler and my vagina throbbed and leaked his copious gism. I sat on the toilet later and tried to expel his fertilising fluids but I knew it was almost certainly to late. Still I had to try.

I slipped into a deep sleep and awoke the next morning, my sheets wet with semen. When I went to the bathroom, another rush of his sperm ran down my legs. I estimate now, that he produced more than a quarter of a pint. I recalled a time in the laboratory when the scientists asked me to assist with the artificial ejaculation of a Great Dane using a steel probe up his rectum and a mild electric shock. That time the animal produced at least that much and it filled a container the size of a cereal bowl. Last night's lover was as big as a Great Dane!

It was time to start work and I went back to the kennels to feed the dogs and clean out the cages. I remembered to collect the video tape. If that was watched by the others, they would get a shock. When I reached the Rottweiller, he looked at me and I actually blushed! I wondered whether his offspring was trying to attach to the lining of my womb as I cleared out his faeces and filled his breakfast bowl. It seemed unreal.

I didn't have sex with any of the animals whilst I waited for my period to begin...or not. Two weeks later I was due and nothing happened. I bought one of those pregnancy tests that you can use even though you are only a day or two late. You guessed it... he'd done me! I was pregnant by a dog and I had no idea what to expect. What would develop? Would it be human or dog like or a mixture of both?

I rang the abortion clinic and asked for an appointment. They said that I'd have to be counselled to enquire into my reasons. Shit! How do you tell a doctor that you don't want to have a creature that might be half human, half dog? I made a counselling appointment anyway and they asked me to come to see them the following week. When I got there the gave me another test which confirmed my pregnancy. At the counselling session the doctor described the proposed procedure...

He explained how he would gradually stretch the opening of my cervix with a series of instruments called dilators. Once my cervix was opened wide enough, he would be able to insert a small plastic tube, about the size of a drinking straw, which would then be attached to a suction machine. The tube would be moved along the inside of my uterus to remove the foetal material. After the suction was complete, he might gently scrape the uterine walls to make sure the abortion was complete. The entire procedure would lasts less than 10 minutes. I expected all of this but wondered if they would examine the foetus and detect an unusual results...

I concocted a story about an unwise one night stand with a black man which the doctor accepted without question and he asked me to return two days later for the operation. When I got back to the clinic I stripped off and had my second bath that day. Immersed in warm water, I looked at my breasts. They already exhibited signs of my condition. They were tender and bloated. I could barely believe my unwise session with a dog had done that to my body. I watched the recording I'd made that night from my bath and witnessed Nero fucking me again. It showed him from behind, humping me frantically, his haunches pumping backwards and forwards like a steam piston. Then I saw the moment when he slowed and stopped and then filled my body with his belly fattener...

The next day I asked one of the vets about his work. I engaged him in a conversation about the plans to get a bitch to carry a human baby. I enquired about the length of normal gestation periods in various animals and he reminded me that dogs only take 13 weeks to produce a litter of puppies. I wondered whether my pregnancy would last 13 weeks or 9 months or even something in between. I finally bucked up the courage to ask him about the experiments with dog sperm and human eggs. I nonchalantly asked about the expected gestation period for this particular mix. He said they estimated that it would be slightly shorter than 9 months but no one knew for sure. He went on to say there were so many variables including the size of the breed that supplied the sperm. A larger breed would produce a bigger baby and take longer to gestate.

It dawned on me later that night that I hadn't had doggie sex for weeks. I decided that I needed a treat, so when everything was quiet, I went down to the dogs. Because of my condition I opted for anal sex instead of vaginal. I had used this technique before, but there are some things that you should consider before you allow your lover to mount you for the purpose of anal sex. You should be experienced with anal sex, by this I mean you should have no difficulty in taking a mans cock inside you. You may wind up with his knot inside you without warning as the dog has most control in this position and will naturally try to lock his cock inside your body. I selected a medium size dog that I had enjoyed before and knelt down and brought my knees forward and tucked them into my stomach with my body resting on my elbows. Soon he was inside me as I guided him into my backside and he humped just like an vaginal sex. I decided to let him tie with me but I had to make absolutely certain that his knot was fully inserted past the entrance to my rectum. If the knot is only half way inside me it would expand both inside and outside of my backside and it may cause the rectal opening to tear causing extreme pain and loss of blood. I managed to tuck him safely inside and winced as it expanded me. It's a lovely sort of pain I recommend you try to get used to. He filled my rectal cavity with his slimy come and I frigged myself to an earth shattering orgasm at the thought of the whole scene which was being recorded again.

The next day I was assisting one of the vets in extracting semen from several dogs using the steel probe method. I decided that evening to try the steel probe on myself to see what it felt like. I sneaked into the main treatment room and unlocked the store cupboard that held all the medical apparatus. These probes came in several sizes and were connected to an electrical device that allowed a varying size of electric current to flow until the dog's system was stimulated enough to cause ejaculation. I took my knickers off and lubricated a medium size probe with KY jelly. My fanny was already wet with anticipation at what was likely to happen to it. I slipped the complete device into my body until only the wire hung from my body as the lips of my vagina closed around it. Reaching for the control box, I set the dial to setting 1 which was the lowest and gingerly pressed the trigger button. Nothing seemed to happen. I switched to setting 2 and felt a mild sensation in my groin. Switching to level 5, I triggered the device and my whole pelvic floor spasmed and then released. My cunt juices started to leak copiously. I panted with anticipation as I switched to setting 8 and paused. What would this be like, I wondered? When I hit the button it was like a kick in my crutch. Wow! What a sensation! It made my whole abdomen kick until the electric pulse subsided. Earlier today, setting 6 would cause the largest dog to come immediately. I manoeuvred the probe until it was against my clitoris. What would a direct electric shock feel like I wondered? I gingerly set the dial to 4 and gathered my breath...then I triggered the pulse. The combination of pain and pleasure made me orgasm instantly. I pressed the trigger switch again and again until I could stand no more. As the repeated orgasms subsided, I rested and caught my breath. The pleasure was indescribable.

I thought of Cedric, a large Afghan hound who had always refused to mount me, even though he had a huge penis and would fuck female Afghans all day. He had always pissed me off for snubbing my advances. An idea came to mind. How would he react to this device? I went down to his cage and woke him from his sleep. Right you choosy bastard, I thought. Let's see how your cock likes this. I muzzled his jaws and put two leather dog leashes around his strong neck. Dragging him unwillingly to the treatment room, I tied the leads to the heavy treatment table legs. He tried to pull away as I went behind him and grabbed his tail. Holding him against my legs, I greased the probe again and positioned it against his anus. He whelped once as I expertly slid it into his back passage. Gottcha! I crowed as I picked up the control panel. He tried to back away as I set it to 5 and pressed the button. His legs almost gave way as he felt the electric pressure on his prostrate gland. He didn't ejaculate but started to develop the biggest erection I've seen on a dog. Two pulses later he was fully erect. What a magnificent cock! It was 8 inches long and so thick! I knelt in front of him and wrapped my mouth around it. It stretched my lips as I just got it in my mouth and felt it bottom against my throat. I gagged a little as I got used to it and sucked him hungrily. He started to subside so I triggered the device to restore his full size. I was in control for the first time with Cedric and there was nothing he could do about it. I switched to setting 7 and pulsed the device. His body stiffened and he ejaculated for the first time right down my throat! What a torrent of semen I felt slipping into my stomach. He involuntarily started to hump in my mouth and I held him steady with both hands. His semen continued to flow as I licked his shaft and sucked at his cock head. Then I noticed that his knot was starting to form as my attentions worked on his genitals for the first time. I hesitated as I realised that here was an opportunity that I had dreamt about for some time. I could let him tie with my mouth and force him to come into my already pregnant stomach for an hour or even longer. The problem was, would it be safe or could he suffocate me if he managed somehow to block my nasal airway.

I was too sexually excited to stop now and I allowed his knot to fill my mouth. It was still expanding and I knew that I probably had only 10 or 20 seconds left to change my mind and back out by pulling away before it expanded and locked me to it. I felt my jaws being forced apart and felt a combination of terror and pleasure at the same time. The tip of his penis was down my throat and was held firmly in place by his massive knot. He had stopped humping by now and I found a position that was comfortable and allowed me to breathe through my nose. He started to shrink again, so I reached for the control. Here it goes girl! I thought as I switched to setting 8 and paused. What would he make of this I wondered? Would I be able to cope with his torrent and still be able to breathe?

I slowly pressed the button and he instantly arched his back and rammed his cock straight down my gullet, pumping torrent after torrent of spunk directly into my belly. I choked and gagged as his steadily recovered from the effect and stopped pulsing. His doggy fur almost suffocated me as I tried to extract him from my mouth. But it was hopeless. His knot was so large that it was like having a fully grown hard orange inside my mouth, holding my jaws painfully apart.
