Tamsin comes of age - Part 2: "The First Lesson" =============================================== (This story is intended to be read as a continuation to Part 1. If bits of this don't make sense, read Part 1 first!) Tamsin sat in her uncle's study, shivering with anticipation. She could still feel the cool metal of the device that was deep inside her, and she was still vaguely aware of a stinging sensation just inside her vaginal opening. Uncle Ben had told her that the stinging sensation would pass soon, and that now that her hymen had been broken, she was now a "proper girl", and was "ready to begin her training". Tamsin didn't know what Ben meant by that, but guessed that she would find out soon enough. Tamsin wasn't that worried anyway, because she trusted her Uncle to take good care of her and protect her. The movie file finally opened on the computer screen, and Tamsin sat forward a little and watched intently. Tania was wearing a hospital gown, of the type normally worn by surgical patients. it came down just below her hips, and covered her body up to her neck. Around the girl's neck was a very shiny, solid metal collar about an inch wide, with a small "o" ring fixed to the front. her sleek black hair was scraped tightly across her head, and tied in a bun at the back of her head. On each wrist, Tamsin noticed a wide leather bracelet which was buckled up and padlocked quite tightly. These leather wrist cuffs each had a large metal "D" ring attached to them. She looked like she was about 4 foot 10 inches tall, and Tamsin guessed that she was about a dress size 2. Tania was smiling, and looked quite excited. Then the camera panned out slightly, and showed the metal frame that Tamsin had seen her strapped to earlier in the day. It was empty, and was made up of a number of different smooth metal panels that could all be adjusted by means of electric motors and rods. This appeared to be so that the occupant could be raised and lowered and angled quite a bit, to give many different possible positions. Uncle Ben was stood behind this frame, and to his left was stood a man who introduced himself as "The Doctor". Tamsin guessed that this must be Doc Jefferson, who her Uncle had said earlier would be visiting tomorrow. The Doctor started explaining some of the equipment that was going to be used. First, he lifted up the breathing tube. He described the way that it would be fed deep into the nasal passage, and then further on directly into the lung to provide a guaranteed supply of oxygen to the body regardless of whether the body was capable of breathing for itself or not. He showed the respirator machine, and tested that it was functioning correctly by holding a balloon onto the tube outlet and watching it inflate and deflate. He then moved over to a metal tray containing four syringes, each filled with a clear liquid. He explained how one of them was a stimulant that would keep the subject conscious and completely alert, how another would dull any physical pain felt by the subject, another would induce temporary paralysis of the subject if injected at the base of the neck into the fluid surrounding the spinal cord, and finally how the last syringe would temporarily disable the diaphragm and halt all natural breathing reactions within the body. He explained how dangerous this final drug was, and indicated to a backup respirator device and petrol-powered generator that was also in the room, should any problems occur with the main equipment being used. Once he had finished explaining this, he picked up the first two syringes and moved over to Tania. The young girl winced slightly as the Doctor injected the entire contents of the first syringe into her slender arm, then she slowly smiled. That, the Doctor explained, was the pain medication. Tania, he explained, would now feel nothing more than dull sensations for the next 6 hours at least. The next injection went in without even a flicker of an eyelid from Tania, and she seemed to perk up significantly and become more aware. Then, after an instruction from the Doctor, she removed her hospital gown and stood naked facing the camera. Tamsin was not prepared for what she saw. Both the girl's nipples had been pierced, twice. Each young nipple carried a nipple bar, as well as a small jewelled ring. There was also a beautiful sun-shaped tattoo surrounding the young girl's navel, and her navel had also been pierced twice. Once above, and once below the belly-button. each piercing held a jewelled bar, and the lower bar had a short chain hanging from it with a small jewel dangling from the end. Tania also had pierced genitals, and Tamsin could see a small silver ring passing through her young, underdeveloped clitoris. The Doctor walked over to Tania holding a long, thin metal hat pin, and kissed the girl on the lips passionately. He then proceeded to insert the pin forcefully into one side of the girl's small left breast, piercing it deeply until it stuck out again the other side some 4 inches along. Tania's expression didn't change, she merely watched with interest as a few small drops of blood collected at the entry and exit points. Satisfied, the Doctor withdrew the pin and smiled. Tania looked down at her bleeding breast for a few moments, then at a word from the doctor she turned around and stood with her back to the camera. Tania's back had also been adorned. She had a large and elaborate pair of angel's wings tattooed across her slender shoulder blades and upper back, and her lower back bore a broad celtic design spreading from the base of her back around to her kidneys and up to the small of her back. Tamsin was mesmerised, and thought to herself that she must ask for permission for a tattoo like that one as soon as possible! The Doctor then approached her with a third hypodermic needle, and proceeded to very carefully insert it into the preteen girl's spinal column at the base of her neck. Once the injection was in, the girl started to sway gently for a few moments and then slowly subsided to the ground. The camera followed her as she slowly collapsed down into a heap on the floor. After a few moments, the Doctor gently lifted the girl up and strapped her into a chair that was nearby. He then wheeled the ventilator apparatus over to her, and prepared the final injection. Tania looked a little nervous as the Doctor fed the breathing tube gently all the way into her tiny body, watching inch after inch of it dissappear into her left nostril and on through to the lungs. The Doctor then taped the tube securely in place on the girl's cheek, and after checking the respirator again he administered the final injection. The effects were sudden - Tania's eyes began to bulge, and her mouth made gagging movements... After only a few seconds, she stopped breathing. The Doctor then switched on the ventilator, and after a few moments the young girl seemed to calm down and regain her composure. The machine evenly pumped air into Tania's lungs, and drew it out again at a steady pace. The Doctor adjusted the rate of breathing until Tania seemed alert and comfortable, and left the ventilator controls, moving out of sight of the camera. After a word from the Doctor, Ben then approached the young girl. Ben, who had been off camera during the girl's preparation. He had undressed, and was now sporting a gigantic erection. He moved over to the girl and positioned her head so that it was near the end of his cock, and Tania opened her mouth. Tamsin watched as Tania reached with her tongue to try and lick the end of Ben's huge cock, and gently he eased the head of his cock into her mouth. After a few minutes of gentle licking and sucking from Tania, Ben started to push it deeper into the girl's tiny throat. First, three inches went in, then four, then five... until eventually, all ten inches of Ben's giant cock were inside the girl's slender throat. Ben then began fucking the girl's mouth rhymically, holding both of his hands behind her head with interlocked fingers. Tania began to make strange gurgling noises, and at a word from Ben, the Doctor quickly held a bucket by Tania's face for her to vomit into as Ben withdrew his penis for a moment. The Doctor explained to the camera that this was a gag reflex reaction by the body, and normally only happened once during these proceedings. Ben gently pushed his cock back down Tania's young throat, and resumed fucking. After some time, Ben began to get more and more aggressive with his strokes, forcing the young girl's face hard onto his body with his massive penis deep inside her throat. After 15 minutes or so, Ben slowed his strokes, and eventually stood still, out of breath, with his penis still deep inside the girl. Slowly, he removed his cock from the 12 year old girl's mouth, and a small amount of cum leaked from the tip as it finally left her lips. Tania reached for it with her tongue, and Ben moved a little closer so that Tania could claim the last few drops. The girl did so eagerly, and then played with it in her mouth for a while before swallowing it down. Ben then reached behind the chair and picked up a large strapon dildo gag, intended to give the wearer a penis where their mouth should be. He reversed it, and gently fed the 9 inch dildo down tania's small throat. When it was completely inserted, Ben reached behind the girl's head and fastened the straps just beneath her hair bun. The Doctor then explained that Tania was going to be subjected to a fertility experiment, and produced another syringe of yellow-green liquid. He explained that this drug was still in the testing phase, and that he was one of a number of doctors who had agreed to assist in testing the new pharmaceutical. The manufacturers claimed that this drug would allow any embryo to develop within a human womb, regardless of it's origin. To this end, the Doctor held up a vial containing canine ovum, or "dog eggs", and explained that Tania was to be implanted with these ovum directly into her womb. He explained that she would then would be impregnated. Hopefully, in two months, healthy puppies would then be born by caesarian section. Tania looked alarmed by this, and her expression betrayed the truth - that she had not been told any of this before she had been rendered helpless!! A stern look from the Doctor caused her to cease her panicking, and she started to smile nervously instead, eyes shining with adrenaline. The Doctor and Ben then gently lifted Tania from her chair, and placed her face-down on the metal frame. The Doctor walked around to the control panel, and pressed a few buttons. Slowly, the frame lifted up and presented Tania's young vagina clearly to the camera. As Ben walked around the frame securing straps around Tania to ensure that the girl did not fall off of the device, the Doctor inserted a large speculum inside her tiny vagina and opened her up wide. From the view that the camera had, the girl's tiny cervix was clearly visible deep inside her body. The Doctor held up the syringe containing the yellow-green liquid, and gently fed the needle tip through the tiny opening of the cervix. He then moved it to one side, and gently pushed until he was sure the head of the needle was embedded deep in the tissue of the womb, and he discharged half the contents of the syringe. He then withdrew the needle, and moved to the other side before repeating the procedure with the other half of the fluid. The Doctor then took a larger syringe with a long rubber tube on the end, and drew a quantity of fluid from the vial containing the canine ovum. He explained that the breed selected was the Rhodesian Ridgeback, because he wanted to see his little girl's belly grow quite large before the birth. With that, he inserted a few inches of the narrow tube through the cervix into Tania's womb. He turned to the camera, smiled, and flooded her womb with the canine eggs. The Doctor then reached over to his trolley and retrieved a large inflatable plug. He quickly removed the speculum and inserted the inflatable plug into the girl's pussy. He then rapidly pumped the inflating bulb until he could see a bulge appearing on her small belly. Satisfied that the eggs were plugged into the womb to settle down, he sat back and Ben moved over to Tania's head again. This time, he was not gentle. He pulled the strap from the back of Tania's head, removed the dildo from the girl's throat and immediately replaced it with his gigantic cock. Ben then proceeded to face-fuck Tania hard and fast for a full ten minutes until, panting heavily, he spasmed and exploded deep into her throat again. This time there was not a single drop left for the girl to lick up, all of it had been fired deep down into her stomach. Ben then left the room, while the Doctor removed the inflatable plug and cleared away the syringes. He then sprayed a clear liquid all over Tania's vagina and legs, and explained that this was canine pheromone. This, the Doctor explained, was to encourage the male dog to mate. He then grinned at the camera, and held up a large butt plug with a fake dog's tail attached to it. Gently, he worked the big plug inside tania's 12 year old asshole until it was completely inserted and secure. Just at that moment, Ben returned to the room with King, his Rhodesian Ridgeback male dog, on a leash. Smiling, the Doctor walked around to the frame's control panel and pushed a button. The frame lowered itself, and raised Tania's genitals up to just the right height for the large dog to reach. The Doctor then opened a large tube of KY lubricant and emptied most of it inside and all around the small girl's tiny vaginal opening. King took very little persuasion, and as soon as Ben unclipped the leash from his collar he was sniffing and licking enthusiastically at Tania's genitals. Ben noticed the doggy tail plug, and made a quiet comment to the Doctor who shrugged and smiled. Ben nodded, smiling, and at that moment King mounted Tania. After just a few seconds, King's large canine cock penetrated Tania and he began thrusting viciously into the young girl's preteen body. King's penis was about 13 inches long, with a large swelling about 10 inches from the tip that was about two inches of the entire length. This swelling already looked like it was about the size of a golf ball. The camera moved to show the view looking underneath the frame from Tania's head towards her vagina. Tamsin saw the young girl's face for a moment while the camera moved, and she saw that the large dildo was still strapped deep inside her throat. Tamsin caught sight of the breathing tube for a moment, and wondered how it would feel to have absolutely no control over her body in the way that Tania was experiencing. She shivered with excitement, and realised that her uncle had gently removed the steel device from her vagina while she was engrossed in the movie. Tamsin felt between her legs, and realised that the chair she was sat on was soaked with her juices. She hoped her uncle wouldn't notice the wet chair seat! Tamsin realised that she could now clearly see the shape of the dog's cock head, moving frantically inside just above Tania's two belly piercings. What first brought her attention to it was that her piercings were being flexed rhythmically and moving as if something was pushing at them from behind. Tamsin tried to imagine the dog's giant penis penetrating deep inside Tania's womb with each stroke. She was glad that the girl had previously been given powerful pain suppressing drugs, or that would surely be agony for the poor girl! Tamsin then noticed a much larger bulge above the vaginal opening on the girl's belly, which was growing bigger. Suddenly, King made one last really deep thrust, and forced it deep inside. The swelling on Tania's belly just above her vagina was huge now, and was visibly growing. King was growling softly. The camera panned back and around to behind King, looking through his legs at Tania's genitals. The clit ring could clearly be seen, glistening with moisture from the frantic and vicious sex as well as the very large amount of lube that the Doctor had pumped inside the girl's vagina before the sex began. Tamsin could now clearly see the very large bulge just above the 12 year old's vagina on her belly, and stared open-mouthed at it twitching and pulsing. King's huge cock stayed firmly locked inside Tania like this, while the camera gradually panned around to show 12 year old Tania strapped securely by her wrists, ankles and neck to the frame. She now also had a number of broad leather straps across her back and around her thighs, to ensure that her position did not change. Because she was temporarily paralysed, Tania was unable to correct her own position or hold it steady. She therefore relied completely upon these straps to hold her securely in place until the procedure was over. While King's huge cock was locked tightly inside Tania's young vagina, the Doctor was explaining in the background how the dog's penis was built. Dog's genitals are very different to human genitals, he was saying. For starters, there is a solid piece of bone providing rigidity along most of it's length. There is also a very large swelling near the base of the penis. This is commonly known as the "knot", and it's purpose is to lock the penis securely inside the body of the bitch while he ejaculates inside her. He then held up a grapefruit, and explained that King's knot was approximately this size when it was fully engorged during a tie. This, he explained, meant that even if King wanted to pull out, he would not be able to due to the very small size of Tania's vaginal opening. He demonstrated the size of the knot by gently pushing on Tania's belly around the swelling, and Tamsin could see that there was definitely something huge, round and firm stuck there under the surface. Dogs, the Doctor explained, can take up to 45 minutes, or somtimes even longer, to finish ejaculating inside their mate. Rhodesian Ridgebacks, he commented, can usually produce up to a half of a litre of ejaculate in one single session. In order to illustrate the point, he reached underneath Tania's frame again and gave her belly a gentle squeeze. The camera moved around to view Tania's engorged vagina, and sure enough a small amount of whitish oily fluid squirted out around the very tight seal between the young girl's pussy and the dog's huge swollen cock. Tania, the Doctor explained, was receiving a very large deposit of canine ejaculate in her womb due to the extended period that King had not been used for breeding. Whilst stroking King's back during the tie, the Doctor further explained that King had not been mated with anyone for at least 6 months now, and that this was his first orgasm since then. He explained that this would create a significant rise in sperm count, and this gave Tania the best chance of concieving due to the sheer quantity that was being emptied inside her womb. He also explained that canine ejaculate is a lot warmer than human body temperature, and that if Tania had not been given the numbing pain-suppression drug earlier she would be experiencing a warming, very pleasant sensation inside her womb. That is of course, he smiled, if she could cope with the pain of having her womb stretched out by such a gigantic appendage! The camera then moved back to show Tania's young body for a while. Tamsin stared at the sight of the 12 year old's pierced belly button, now pushed out by the head of a gigantic dog cock from inside, and tried to imagine how that would feel. She imagined how Tania would be feeling, knowing that she was becoming impregnated with dog sperm and would be carrying puppies for two months. Every now and then, King would move and adjust his position. Tania groaned slightly from time to time when this happened, and Tamsin could see King's huge knot stir under the surface of Tania's tummy. Sometimes, a small squirt of dog ejaculate would leak out from the girl's over-filled vagina. Tamsin thought she could see the girl's tiny flat stomach becoming slightly swollen with fluid around her belly button piercings. She noticed that the piercing with the small chain hanging from it was twitching every second or so, as if something was being squirted at it with some force from inside. Eventually, King's knot began to subside and he became restless. At this point, both Ben and the doctor gently secured King's hind quarters to the bench and the Doctor administered an injection to the nape of King's neck. This, he explained, was to calm King down enough that he would not try to pull out before his knot had fully subsided. The main reason for this was to attempt to maximise the quantity of sperm deposited. Another reason was because Tania may need surgery to repair serious vaginal tearing if King managed to pull his grapefruit-sized knot out through her small preteen vaginal opening too soon. After a further 10 minutes, the swelling just above Tania's vagina on her tummy subsided enough for King to safely pull out. The camera moved around to view the young girl's genitals for this event. Ben and the Doctor slowly removed the straps still holding King's hind quarters, and King slowly slid away from Tania's back. Gradually, the Knot appeared. Still the size of a tennis ball, it stretched the skin of her tiny pussy almost to breaking point, then... POP! Out came 13 inches of dog cock along with a wash of milky, watery white liquid which went all over Tania's back legs and into a bowl that had been placed beneath her. The Doctor picked up something that looked like a turkey baster, and sucked up as much of the wash of ejaculate into it as possible. He then pushed all 9 inches of the baster slowly inside Tania's swollen vagina and gently discharged it's contents into her womb. With the baster still inside the girl's vagina, the Doctor pressed a button on the frame she was mounted on. The young girl's body was moved so that her hind quarters were raised up, and her torso was angled to about 45 degrees with the ground. The girl's head was not far from the floor, but her legs were hanging straight down from her hips.
