Tamsin comes of age - Part 1: "Tamsin's Discovery" ================================================= It was an incredibly hot summer that year. There were water shortages, heatwave health warnings on TV, and the freezer at Tamsin's Uncle's house was permanently well-stocked with ice-cream - so things weren't all bad! Tamsin was staying at her uncle's house that summer whilst her parents were working abroad in europe. They worked abroad a lot - they both served in the military and were away for months at a time. Tamsin didn't mind much though. In fact, Tamsin loved staying at her uncle's house - he had a big pool, a jacuzzi, and even a sauna house in his back yard. He also had a great big dog called King, who was always very loving and protective of Tamsin. On many of those long, hot summer days, Tamsin and King would often be found lying in the cool shade among the palm trees at the bottom of the garden, having a quiet nap. Tamsin had known king since he was a pup, some 4 years ago now, and the pair had become very close in that time. Originally, Tamsin's uncle had bought King to protect his new home in this neighbourhood, when burglaries and breakins were on the rise in that part of town. Being a male Rhodesian Ridgeback, King was a fearsome and effective deterrent to the local low-lifes that cased the houses in that area, even at a young age. On this particular hot summer day, Tamsin was lounging by the pool in her bikini. It was two weeks to her 10th birthday - her "double digits" day as Uncle Ben liked to call it. She was very excited. Tamsin knew that her Uncle had spent a lot of time and effort planning a surprise party for her that year. All the details had been kept strictly secret from Tamsin. Ben even went as far as locking the door to his study and putting on music whenever he was organising a part of the day on the phone, or using the web to arrange things. That was where Ben was now - locked away in his study, organising things for her "double-digits" day. Tamsin didn't mind - she liked surprises anyway. Last year, Uncle Ben had paid for a 4-month intensive horse-riding and pony-riding course for her! That was so cool! Maybe this year, she might even get a pony of her own! Uncle Ben had the room for one, anyway! Bored with sunbathing, Tamsin decided to go in the house and get a cold drink. whilst walking past the door to Uncle Ben's study, she thought she heard a strange noise, sort of a cross between a gurgle and a moan. Ben hadn't turned his music on this time, because he had thought Tamsin was asleep by the pool. Tamsin peered in through the keyhole in the door and caught sight of the computer screen on Ben's desk. What she saw made her jaw drop, and her eyes widened. The screen was showing a video of a naked girl strapped securely on her belly to a strange metal frame, while an older man thrust his very big penis into the girl's mouth. The girl looked like she was about 12 or 13 years old, but it was difficult to tell exactly because she was also blindfolded with a scarf that covered most of her face. she was also wearing a strange collar around her neck that looked like it was made of solid steel. This had a metal ring attached to the front. This ring had a metal clip hooked onto it, the other end of which was fixed to the bench. This was keeping the girl's head still and stopping her from escaping. The older man was rhythmically fucking the girl's mouth with his penis, and the gurgling noises Tamsin heard were the sounds of it going in and out of the girls throat by some 6 or 7 inches. As Tamsin watched, she saw the older man completely remove his penis from the girl's mouth, and she marvelled at the size of it. It just kept on coming out! the guy must have had that thing all the way down her neck! Tamsin had seen a penis before, but never thought that they could be as big as that! one day when she came back from a riding lesson last summer, the stable hand was masturbating in the stables when Tamsin rode back in. Tamsin didn't know what to say, and she never mentioned it to anyone. She would never admit it, but since that moment she had been fascinated by penises of all kinds. She had seen King's too, once, when he was cleaning it. She thought it just looked weird - all red with blue and purple veiny bits on it. As Tamsin stared open-mouthed at the gigantic penis being removed from this girl's throat, she saw the camera pan around, back and across to show the rest of the girl's body. Tamsin saw what looked like a giant rubber penis inserted in the girl's vagina, and another one pushed very deep inside her anus. These were fixed to a machine, and it was slowly moving the huge toys in and out of the girl by about 8 inches or so. Yet another machine was gently pumping what looked like a thick, clear liquid through two narrow tubes, one in her vagina and the other in her anus. These tubes were securely fastened in place by tape, and Tamsin could see bubbles in the fluid flowing along the tubes and into the girl's body. Every now and then some of the clear fluid would leak out of the girl's vagina or anus in a brief squirt, and then run down the girl's legs and onto the floor. Just then, the girl let out a long scream that seemed to be half pleasure, half agony. The camera panned back to the girl'sface just in time to see her in the final throes of a massive orgasm. The blindfold had been removed, and the girl's piercing blue eyes were transfixed on something out of sight while her teeth gnashed, and her whole body shook. Tamsin had never had an orgasm before, but she had heard about them from friends at school and they sounded pretty cool! She guessed correctly that this was what one might look like. It looked pretty wild, and Tamsin decided she wanted to try that as soon as possible, but the method shown in the video looked a little scary!! Just then, she heard a sound from Ben in the room. She shifted across to get a different angle through the keyhole, and saw Ben sat in his leather chair, holding his penis in his hand and stroking it hard. Tamsin did a double-take, and suddenly realised - that was the penis in the video!! "Oh my god, it looks bigger in real life!" Tamsin whispered to herself without thinking. Suddenly, the video dissappeared from the screen and Ben started to put his gigantic penis away in his pants. "Shit, he heard me!" Tamsin thought, and ran back to the pool to lie back down. Ben wandered out a few minutes later, holding a glass of lemonade. "I think you forgot this outside my study, Tammi!", he said with a smile. "Were you just spying on me through my keyhole?" "Um.. no Uncle Ben... I mean... I heard noises when I went to get a drink, and I saw the video of a girl on your computer screen... and it looked like you were in the video too..." "Oh dear", Ben said. "You weren't supposed to know about that yet. You're still only 9 years old, and I promised your parents I would wait until your 'double-digits' day before I let you know about all of this. What makes you think I was in the video?" "I... um... saw your thingy... and it looked just like the one on the video", Tamsin blurted. Ben laughed. "You saw my thingy? It's called a 'Cock', Tammi. And yes, that was me in the video." "Oh, ok - I saw your cock then!", she giggled. Tamsin thought for a moment, then asked coyly, "Can I see it again?" "Are you sure?" Ben asked - surprised by this request. "Yeah, definitely. I wanna know what they look like properly, and stuff", Tamsin said nervously. Ben could see by the wetness on Tamsin's legs and on her bikini bottoms, that she was really aroused by the whole idea. "Ok, but no touching unless I say so." said Ben. "Aw, please? I just want to have a good look!" moaned Tamsin. Ben just gave her a stern look, and then smiled and undid his pants. Ben's massive erection from earlier had subsided a little, but it was still an awesome sight. It was almost as thick as Tamsin's arm, and at least 10 inches long. Tamsin marvelled at how anyone could fit the entire thing into their mouth, like the girl in the video had done. Tamsin remembered seeing those balls resting on the girl's chin, and tried to imagine how it would feel to have something that big going down her throat. Tamsin had not thought about it at the time, but now she remembered seeing a small clear tube going into the girl's nose. She guessed that the tube must be letting the girl breathe. In actual fact, the tube had been inserted into the girl's lung and was breathing for her whether she wanted to or not. The combination of pain-suppression and muscle-relaxant drugs that had been injected directly into the young girl's spine shortly after filming started, had the interesting side effect of temporarily paralyzing the subject from the neck down. The drugs also stopped the diaphragm from working, which would have meant death by suffocation if that breathing tube had not been inserted and the respirator not been switched on. Whilst under the influence of these drugs, all that the subject felt was a dull level of physical sensation. Thankfully however, her mental state was not affected at all. The breathing tube essentially meant that the girl's mouth was not needed for air, and so became available to be used for other things. Fortunately, the effects of the injections lasted only a day or so, after which the subject regained full motor control and was back to normal again. That is, of course, unless further injections were administered. Tamsin reached over and touched Ben's penis, which was by now becoming engorged with blood again and regaining it's former glory. It really was huge, and Tamsin sat open-mouthed as she explored it. The skin felt velvety soft, and there were dozens of bumpy veins along it's length which rippled under her hand when she stroked it. Ben let out a soft moan as Tamsin stroked his cock, and Tamsin looked up worried. "I know you said not to touch, but I couldn't help it!" Tamsin bleated. "Don't worry Tammi, it's ok - you can touch for now. But nothing else, understand?" Ben said. Tamsin didn't know what "else" there was to do at that point - so she just explored and stroked. At one point, she took the head of it inside her mouth to see how much she could take, thinking again of the girl in the video. She only just managed to get the head in her mouth before she couldn't manage any more. Tamsin looked up, and asked shyly, "Who is the girl in the video?" "That's Tania, Doc Jefferson's daughter. She'll be coming over to visit tomorrow, along with the Doc." Ben said. "What were you doing to Tania, Ben? It looked like it might hurt - and you had your cock thing all the way inside her throat too? wasn't that a bit mean?" asked Tamsin. "Actually Tammi, Tania asked for me to do that to her before the video started. And it would have hurt a bit too, if the Doc hadn't given Tania some medicine to make it easier on her" said Ben, smiling. "Oh! Tania looked like she was enjoying herself in the video though - but I can't imagine how!" she said. Tamsin speeded up her stroking now, in response to Ben's heavier breathing. Ben started to moan, then suddenly grabbed Tamsin's head and thrust the head of his penis into her mouth. Tamsin gagged and tried to pull away... Then suddenly Ben's penis exploded into an orgasm in her throat. Tamsin felt huge amounts of hot cum hitting the back of her throat, and going down before she had a chance to spit it out. What little of it hit her tongue tasted oily, slimy and salty-sweet. When Ben had finished ejaculating into Tamsin's throat, he pulled away and smiled. Tamsin coughed and spluttered, and panted until she caught her breath. "That was intense, Uncle Ben! Did you have to shove that thing in my throat? I couldn't breathe!" Tamsin spluttered. "Sorry baby, but I got carried away there. What did you think of the taste?" Ben asked. "Hmm... I liked it, though it was a bit slimy! I'd find it hard to manage much more of it than that!", she smiled. "We shall see", said Ben, with a strange look on his face. They lay down by the pool, cuddling. Ben's enormous penis was still out, and even when flaccid Tamsin was amazed at it's size. She lay idly playing with it for a while, exploring how it moved, feeling Ben's heartbeat pulsing through it. Every now and then when Tamsin touched the head, it would twitch and Ben would smile. "That part is very sensitive, Tammi. Be gentle when exploring that bit!" Ben said softly. "Ok, sorry! It's all a bit new to me. I guess I've got a lot to learn!", Tamsin giggled. "You don't know how right you are, Tamsin. In fact, I had intended to get you started gently on some of that learning later today. What do you say, are you up for it?" Ben inquired. Tamsin just smiled and nodded, her eyes shining with anticipation. Ben's penis began to harden again, and Tamsin grinned - she wanted to try a bit more of that cum stuff, to see whether she really did like the taste. Later that day, Ben and Tamsin were sat on one of the big leather sofas watching TV. "Ben, y'know that video I saw a bit of earlier?" Tamsin looked at Ben inquisitively. "Yes, Tamsin, what about it?" Ben asked. "Can I see it? All of it, I mean?", Tamsin asked hopefully. "It's over four hours long, Tammi - and some of it might upset you. You might not be ready to see some things yet, darling." Ben answered. "Aw, please? I don't have anything else to do today - and besides, if something upsets me you will be here to look after me won't you?", she asked hopefully. "Ok, I'll show it to you. But not a word to anyone about what goes on in that film, understand Tammi? I could get into a lot of trouble." Ben warned. "I promise. My lips are sealed, I won't speak to anyone about it. I love you, Uncle Ben. I wouldn't do anything to get you into trouble." Tamsin said solemnly. "Ok", said Ben. "Let's go into my study." Tamsin had never been inside Ben's study before. There were all sorts of weird things hanging on the walls - chains, handcuffs, leather collars, and one wall had a big collection of fake penises of varying sizes. The penises ranged from toys about the size of a finger to ones as big as Ben's cock, and even bigger than that! They were in all sorts of weird shapes too, and some of them had a hose and a bulb attached. Tasmin guessed correctly that those ones were inflatable, and could be made even bigger by pumping them up once they were inside someone. She also noticed a shelf with a number of steel collars on it, much like the one she saw Tania wearing in the video. Next to those collars on the shelf was a soldering iron, and some solder in a plastic tube. "No girl may wear clothes in my study, not even my darling niece. You will need to strip, OK Tammi?" Ben said sternly. "erm... I am only wearing a tiny bikini anyway - do I have to?" Tamsin protested. Ben just gave her a stern look, and Tamsin nodded and removed her bikini. Ben looked his niece up and down, and smiled. Even at the age of (nearly) 10, her budding nipples were showing signs of promise for things to come in the years ahead. Her small cleft was bare, and still seemed to be glistening from the arousal that had happened earlier. Ben smiled at Tamsin for a while, then suddenly remembered himself. "There's something else you will need to do before we watch the video. Are you still a virgin, Tammi?" Ben inquired. "Yes, Uncle Ben. I kissed a boy earlier this year in class, but thats all." Tamsin knew what a virgin was. One of her friends at school had started calling everyone else a virgin one day, and Tamsin managed to get out of her that her friend had lost her virginity to her older boyfriend, and she had given a fairly detailed account of what had happened. Tamsin didn't completely believe her friend at the time, but she was beginning to now. "What else have I got to do, Uncle Ben?" "You need to have your hymen broken. It's going to hurt a bit. Are you ready?" Ben asked. Tamsin wasn't sure what a hymen was, but she trusted Uncle Ben completely so she shakily nodded her consent. Ben smiled, and reached over to his wall of fake penises. Ben thought for a while, then picked one out that looked like it was made of smooth metal. It had straight, sleek sides, a rounded tip, and what looked like a push-button trigger at the base. Ben held the toy carefully, then got out a sterile wipe from a drawer and proceeded to clean the toy thoroughly. Then he pressed the trigger, and Tamsin jumped. A click was heard, and she thought she saw a tiny blade stick out a few millimetres from the tip, and then go straight back in again. "What is that?" Tamsin asked, starting to feel a little scared. "It's a device the Doc and I designed. It's for breaking the hymens of girls in the easiest, quickest and least painful way possible Tammi." Ben said. "Instead of stretching it and ripping it with something blunt like most girls have to endure, this quickly slices it open, no stretching or ripping is involved." Ben explained. Tamsin nodded apprehensively, and Ben reset the spring in the device. Ben then broke the seal on a new tube of KY lubricant, and smeared the lube generously all over the device. "Hop up onto my desk, Tammi", said Ben. "I want to make sure this is done properly." "Ok - like this?" Tamsin asked, as she climbed up and sat with her legs apart, facing her uncle. Ben smiled. "That's perfect, darling. Now - are you ready?" He asked. Tamsin shivered, and nodded quickly. Without warning, Ben quickly inserted the device inside Tamsin's virgin pussy as far as it would go - which turned out to be about an inch and a half. Tamsin felt the cold metal device pushing against a wall inside her, then suddenly... CLICK! Tamsin jumped, half expecting it to hurt like hell. All she felt was a slight stinging sensation, and when she looked down all 7 inches of the device were buried easily inside her pussy. Tamsin looked up at her uncle and smiled. "That wasn't so bad! It actually feels nice, this cold metal on such a hot day!" "You handled that very well, my darling!" Ben said. "Well done. Now, you are ready to watch the movie." "Yes please, uncle Ben! I've been thinking about it all afternoon!" enthused Tamsin. "OK, here we go", Ben said, and opened up the video file on his computer.
