Tony and Tonya are German shepherd twins living alone on a cattle ranch out in the country. They tragically lost their parents a year ago in a car crash, but the two of them are determined to keep the family farm going on their own. For a while things go pretty well, but one day Tonya comes down ill unexpectedly. With only Tony to take care of her, it's up to him to figure out what's wrong and do what he can to help. After all, what are brothers for?

On the Farm

"Other things may change us, but we start and end with family."

  • Anthony Brandt

******

Almost done...

With a steady hand, Tony squeezed a few drops of glue onto either end of the matchstick held between his fingers. He tried not to shake too much in excitement. For the last three weeks, he'd been waking up early and going to bed late, working on a model of the Empire State Building. Today, he'd gotten up extra early, before three o'clock, knowing that he was almost finished with his project. For almost two hours he'd been painstakingly gluing matchsticks to the spire at the top of the building, and now he was holding the last one. Keeping his hand as still as he could, he gently but firmly pressed the small sliver of wood in place.

"Perfect," the German shepherd said to himself, leaning back from the model with his tail wagging happily. At only five feet tall, the model was a foot and change shorter than he was, and not even close to the nearly fifteen hundred foot height of the actual building. Even so, it looked to him like an impressive scale representation of the real thing.

Tony had many such models in his room, and scattered about the three-story ranch house that he lived in. Indeed, one couldn't find a room in the house that didn't have at least one or two of his creations. Model building was his hobby, but he didn't like making things from a kit. He preferred doing things from scratch. Whether he was using matchsticks, popsicle sticks, or just twigs that he found around the three-hundred-acre ranch that his family owned, he just liked the more personal touch when it came to model crafting. Tony's favorite subject for construction was real-life buildings, like the Empire State Building, but occasionally he would make models of animals, people, or vehicles. A large popsicle stick model of a jet airliner hung from the ceiling of the first-floor living room, one floor below his bedroom. He'd built that a couple of years prior, and his parents had been so pleased by it that they'd insisted on displaying it where everyone could see.

Now, though, he built models just for himself. Nearly twelve months ago, his parents had been driving the family truck into town, hauling a trailer with five calves that they were going to auction off to other ranchers. On the way in, a midday drunk driver had run the truck off the road and into a ditch. The calves had come out okay, with only a few scratches, but his parents hadn't been so lucky. Tony still remembered getting the call from the county sheriff, telling him the news that he and his twin sister, Tonya, were now orphans.

Things had been pretty difficult for the first few months after their parents died, but luckily the twins had family in the area, though where they lived "in the area" meant scattered over hundreds of square miles on various ranches and farms. Their aunts and uncles had offered to take them in, but he and Tonya had decided pretty quickly that they were determined to keep the family ranch. That meant caring for the thirty head of cattle, six horses, and chickens all by themselves, but the twins had been working on the ranch almost as long as they'd known how to read and write. Every now and then one of their relatives would stop by and check on them, but for the past year they had run the ranch entirely on their own and done a pretty good job of it. Though Tony had to admit that Tonya was a lot better rancher than he was. Tony was pretty scrawny for his age and height, and while Tonya was a good deal shorter than he was, she weighed about the same and was definitely stronger.

"Tony, are you up yet?" There was a bang on Tony's bedroom door, and without waiting for a response, his sister Tonya opened the door and looked in on him. While Tony was still shirtless in his pajama shorts, Tonya was already prepared for the day. She was dressed in beat-up jeans, boots, and a red flannel long-sleeve shirt buttoned up to her collarbone, leaving the top button undone. She also had a blue patterned bandanna tied around her neck. It was the sort of outfit that their mother would have worn for a day of work on the ranch, and the female German shepherd really did look a lot like a younger version of her mother.

"I've been up for hours already," Tony responded, looking up from his model. "Check it out. Finished up the Empire State Building!" He gestured to the model with a grin on his muzzle, stretching his arms wide to emphasize his feat. The response from his sister was less than overwhelming.

Crossing her arms, Tonya rolled her eyes. "Look, Tony, that's impressive and all, but the cows aren't going to milk themselves. Get your rear in gear and let's get moving, already. Breakfast is on." She walked off, leaving his bedroom door hanging wide open as her footsteps vanished downstairs.

Feeling a bit deflated, Tony let his arms sink to to his sides. "A little appreciation would be nice..." Smoothing the fur between his ears, he got up from where he'd been working and went to his dresser. After putting on a pair of pants and a well-worn work shirt, he pulled his own boots on and went downstairs to join his sister for breakfast.

******

Around midday, Tonya was working in the horse barn, mucking out the stalls and bringing in fresh hay for the horses. The morning had been a typically difficult one, with her and her brother going about the ranch conducting their daily chores. After a hearty rancher breakfast of steak strips, fresh eggs from their chickens, and bacon from a neighboring farm, they left their house and started off with the cows. While they were primarily a beef ranch, they also had a few dairy cows who provided milk for their own use as well as for several specialty cheesemakers in town. Tonya's parents had never believed in farm technology much more than a tractor or a truck to haul things around, and so the milking was done by hand. By now, she was an expert at it and so was Tony. They had all four milk cows taken care of within thirty minutes.

The next task had been to take the truck out and drive the perimeter of their ranch, checking the fencing to make sure that none of the free-range cows had damaged it during the night. Not that the fence was that flimsy, but one could never tell what a cow might do out of curiosity. Fortunately, an hour's examination assured Tonya and Tony that the wooden-post fencing was as strong as ever. Once they'd finished, they went back to the ranch house and swapped out trucks, taking a flatbed with a large water tank on it and driving around inside the fence. While Tony drove, Tonya hopped out periodically and filled large water troughs from a hose leading from the tank, so that the cows would have drinking water during the warm autumn day. While they did that they could check on the cows at the same time. As free-range animals, they stayed outside all the time, and neither of the twins interfered much with them unless they needed medical care. All of them seemed to be well, so they finished filling the water troughs and then went on to take care of the chickens.

Next, they each took one of the horses for a ride around the ranch. They had six horses, four mares and two stallions, and all of them were trail-riding breeds. Tonya loved riding, and it was good exercise for the horses. She and her brother tried to take two of them riding every day. Her favorite was one of the mares, named Petunia, and he preferred riding the stallions, Jody and Will. Today, Tonya took Petunia out while Tony saddled up Will. They rode the horses hard for an hour and then brought them back to the barn, where they fed and watered all of them together before setting them out to pasture for the day.

When all of the morning chores were nearly done, it was nearing lunch time. Tony left Tonya to muck out the horse barn by herself so that he could go up to the house to get lunch going. She always preferred doing this by herself, anyway. When her mother had still been alive, she and Tonya had taken care of the horses together. The German shepherd felt like she could still be close to her mother this way, even though she wasn't around anymore.

Mucking out the barn was tough work, but Tonya liked it all the same. As she cleaned out each stall, seeing the place become just that much cleaner, she felt a growing sense of accomplishment. Even the growing heat of the day didn't diminish her spirits. In fact, it seemed like an unusually hot day for the fall, and Tonya was growing a little dizzy as she hauled in hay to stock each of the stalls. Shaking her head, she figured she was just getting dehydrated. Putting down the pitchfork, she walked to one corner of the barn where a rickety old refrigerator was plugged into the wall, and grabbed a cool bottle of water. Downing the water in several long gulps, she felt a little better. Tony always told her that she worked too hard, but she loved the ranch that they called home, and she wanted to make her parents proud of her even if they were no longer there to see her.

Refreshed, she went back to work. She was still dizzy, but the water had cooled her off and made the interior of the barn seem not quite so hot. Picking the pitchfork back up, she realized it seemed a little heavier than before, and she began feeling more tired as well. Tonya hadn't ever felt this way before. Maybe she was just hungrier than usual, but normally she could get through a whole work day and even skip lunch without feeling any ill effects. There wasn't any reason she should be feeling this way.

Maybe I need a little fresh air, the female fur thought to herself. It is pretty stuffy in here._Shaking her head again, Tonya dropped the pitchfork and walked outside to the nearby fence line, leaning against it. Waves of weariness were washing over her, and her legs were curiously weak. She shifted, her thighs rubbing against each other. There seemed to be a strange smell in the air around her, and if she didn't know any better she would have thought it was coming from her. _Maybe I did work too hard this morning...I should...

As Tonya turned to walk back to the barn, her legs gave out, and she slumped to the ground. Before she could even register what was happening, she had fainted dead away.

******

When he got back to the ranch house, Tony parked the truck near the front door and went inside. Every week, he and Tonya switched off duties as the cook, and this week was his turn, so of course it fell to him to make lunch. The only reason his sister had made breakfast had been that he'd lost track of time that morning. He privately thought that Tonya was a much better chef than he, having learned from their mother while she was still alive, but he knew his way around the kitchen, too. The question was, what was he going to make for lunch?

Tonya seemed a little tired while we were riding...,_the male German shepherd mused. _Maybe something high-energy. Going to the rather expansive pantry, he pulled out some noodles and some jars of preserved fruit. A pot of high-carb pasta and a jam roll for dessert seemed like just the thing that would give his twin sister a boost. With the menu decided, he got to cooking.

As he pulled the jam roll out of the oven some time later, Tony glanced at the clock. He was a little late with finishing lunch, but Tonya still hadn't arrived back at the house. He was a little surprised by that; usually cleaning the horse barn didn't take her much time at all. He put the tray with the dessert on the kitchen counter to cool and turned the noodles down to warm so they would stay hot, and then he tugged his boots back on and went outside to take the truck down to the barn. If Tonya needed help finishing up, the food would keep until they got back.

Tony drove down the gravel path from the ranch house down to the barn, humming a little nonsense tune as he did. He was already thinking about the next model he would start working on. The last three things he'd made had been buildings, all made of matchsticks. Maybe next he'd try constructing a ship model. He'd never done one of those before, and he had a huge box of popsicle sticks that he'd been dying to do something with. If he was particularly adventurous, he might even try making this one watertight so that it could actually float.

Parking the truck next to the horse barn, Tony hopped out, still humming and wagging his bushy tail from side to side. He walked into the barn and looked around. Tonya wasn't inside, and the place only looked about three-quarters of the way clean. He stopped humming, frowning slightly as he surveyed the floor. It almost looked like Tonya had abruptly stopped the job, as he could see the broom lying rather haphazardly on the floor.

"Tonya?" he called, walking towards the other side of the building. "Lunch is ready, are you in here? Where'd you go?" The German shepherd crossed to the door which led out to the pasture, still calling out to his sister with no answer. Growing worried, he rushed outside, looking around wildly, his eyes suddenly falling on a spot on the ground nearby. "Tonya! What's wrong?"

Rushing over, he knelt down by his sister, laying on the grass on her belly. He put an arm underneath her, lifting the sixteen-year-old girl until her head was in his lap. Frantically he checked her vital signs. Tony was no doctor, but he did have some limited veterinary experience, as to be expected from someone who grew up on a ranch. Tonya's pulse seemed strong, and her breathing was regular, if a little heavy. He laid a hand on her forehead, and then touched a few fingers to the tip of her muzzle, feeling her black nose. Her temperature was high and her nose was dry, feeling warm and rough to the touch. That wasn't good at all; a healthy nose should be cold and wet. Also, there was a strange smell about her, faint, but noticeable. Tony had no idea what it was, but it was definitely coming from his sister.

Tonya stirred, turning her head to one side. "Hot...," she mumbled, sounding delirious. "So...hot..." Her eyes opened to slits for a brief moment before closing fully again.

"Oh, man, you must be really sick," Tony said anxiously. "I need to get you inside." He put one arm underneath her back and his other underneath her knees, lifting her up with a little difficulty. Tony carried his sister back through the barn and to the truck, lifting her up into the passenger seat. He ran around to the driver's side and jumped in, cranking up the well-worn engine. Before he threw the vehicle into gear, he glanced over at Tonya. She was motionless, her normally tall, pointed ears lying flat to her head. As he turned back to look forward, his nose twitched. That scent he'd detected before was there again, and now he knew it was definitely coming from his sister. In the enclosed space of the truck the smell was much stronger. Whatever it was, the smell was awakening something inside of his mind, although he couldn't really put it to words.

Shaking his head to clear it, Tony shifted the truck into drive and whipped it around, heading up to the ranch house as quickly as he could. He hoped that whatever was wrong with Tonya, he'd be able to help her by himself. They _really_couldn't afford an expensive hospital stay, not until they sold the maturing beef cattle. Hopefully some rest was all that she needed to be sorted out...

******

Slowly, Tonya came awake, her eyes fluttering open as consciousness came back to her. When she had enough of her wits about her, the female canine sat up, looking at her surroundings. A few moments passed before she realized where she was. She was lying in a bed, with all of her clothes on (save for her boots), in a room that was familiar to her. This room and bed had belonged to her parents, and she and Tony had kept it in perfect condition ever since they died, sort of as a memorial.

She looked at the blue plaid-patterned sheets, soft and comfortable. This bedroom was on the ground floor of the ranch house. Tonya had memories of when she was a little girl, on the occasions when she'd had a nightmare. She'd come thundering down the stairs as fast as her short legs could carry her and burst into her parents' bedroom, in tears. When both of her parents came awake, her father would grumble good-naturedly and her mother would help her up into the bed. Once the initial scare of the bad dream was over, and her parents were comforting her, she'd fall asleep. When she woke back up in the morning, she'd find that one of her parents had carried her back up to her own room.

Tonya sighed and laid back down again, rubbing a hand over her furred forehead. How did I end up here?_she wondered. The last thing she could remember was feeling woozy in the horse barn, and then she thought that she must have fainted. _I still feel pretty funny...

Now that she was relaxed and in a quiet place, Tonya tried to figure out what was going on with her body. She still felt very hot, even though she knew that the ranch house's air conditioning was on. She was also having trouble thinking straight, and she had the sense that there was something she had to do. If she had to describe the feeling, she would call it a sense of urgency, although there wasn't anything pressing that she needed to attend to, at least not that she could think of. What's more, there was a most uncomfortable feeling between her legs, an intense tingling and throbbing. Curious, and a little embarrassed even though she was alone in the room, she placed a hand on her crotch over her pants. Tonya was surprised to feel noticeable warmth beneath her fingers, as well as a slight dampness that had soaked through the fabric of her jeans.

I, uh...huh..., Tonya said to herself, feeling a blush rising to her cheeks. I must have been having a really_good dream, or something._ If Tonya had been having a sexual dream, it wouldn't be the first time. As a healthy girl of sixteen years, she wasn't any stranger to fantasies or masturbation. But the feeling, which she was now able to recognize as arousal, was a little more profound than when she indulged in herself.

Just as she was about to slip a hand under the waistband of her jeans, to check just how wet she was, she heard a knock at the door. Tonya jolted upright, then gave a muttered curse as she felt a rush of lightheadedness. She jerked her hand up above the covers, pressing her fingers to her temples, massaging the light throbbing away. "Come in."

The bedroom door opened, and Tony poked his head inside. "Hey there, uh...You doing any better?" He stepped into the room, and Tonya could see that he had a tray in his hands.

Tonya leaned back against the headboard. "A little better, I guess. I'm still kinda woozy. What happened?"

"I'm not sure." Tony walked over to the bed, putting the tray down on a bedside table. "I came down to get you for lunch, and I found you on the ground outside of the barn. I guess you're coming down with something. You looked a little worn out this morning, so maybe you worked too hard?" He sat down on the edge of mattress, looking at his twin sister. "How do you feel?"

"Weak...Tired...And I'm really hot." Tonya shifted underneath the blankets, wanting to get out from under them but not wanting to risk the possibility that her brother would notice any dampness on her jeans. "Can you turn the AC up any? I'm burning up..."

"It's already up pretty high," her brother said, "but I guess I could turn it up a little more in a minute. For now, I thought maybe you could use something to eat."

Belatedly, Tonya realized that she hadn't had any food since breakfast, and looking at a clock hanging on the wall she could see that it was already mid-afternoon. Her stomach began rumbling, as a further revelation of her hunger. "I guess some food does sound pretty good. What do you have?"

Grinning, Tony reached back and picked the tray up, lifting it over to her. "It's nothing much. Just what I'd made for lunch. Buttered noodles and some jelly roll." He pulled the lid off of the tray, and a cloud of steam came up. The noodles looked pretty good, even if they were a little rubbery from having been made hours ago, and the jelly roll was no worse for having been out for a while. "The food's reheated, but it should still be good."

Tonya had to admit that it looked great, and she was starving. She balanced the tray on her lap and picked up the fork he'd provided for her. Twirling some of the noodles around the utensil, she took a bite. Chewy, but... "They're really good," she said, breaking into a smile. She set into the meal with enthusiasm while her brother watched, seemingly pleased that she liked it. When she was finished eating, he took the tray and put it back on the bedside table.

"So, uh...," Tony said, looking back at Tonya. "Any idea what's wrong with you? I mean, I've never seen you faint before."

Looking uncomfortable now, Tonya glanced away. She had a hazy idea by this point of what was wrong with her, but she still wasn't sure. "I mean, I don't really know...I just started feeling really tired and weak. I thought I was just dehydrated, but I fainted even after I drank some water."

Tony tapped his foot on the floor thoughtfully for a moment. "You know, mom and dad had that old home medical guide on the bookshelf out in the living room. I think it's still there. Maybe that'll have some answers?"

"I guess it's worth a try," Tonya said.

"I'll go get it, then." Tony got up from the edge of the bed, taking the empty tray with him, and crossed the floor to the door. When he got to the threshold, he paused, his nose twitching. Now that the smell of the hot food was out of the room, he could smell something else. That same thing he had smelled when he was bringing Tonya back from the horse barn. "Hey, Tonya, did you put on some kind of perfume today?"

Tilting her head curiously, Tonya gave him a quizzical look. "Perfume? No, I don't wear perfume. Why do you ask?"

"It's just...I could swear I smell something. I smelled it before, when you fainted outside. I dunno how to describe it, but it's kinda...I dunno, a nice smell. You sure you don't have anything on?"

"I don't know how more clearly I can say it, Tony. I'm not wearing anything. You're probably imagining it."

"Well...Yeah, maybe. Anyway, let me go get that book." Tony walked out, pulling the door almost closed but not latching it. His footsteps trailed off as he walked down the hall.

Once she was alone again, Tonya slid herself out from underneath the covers. She was just feeling so hot, she needed to do _something_to help herself cool off. She unbuttoned her shirt, shuffling the red garment off and dropping it on the floor. The German shepherd tugged off her long socks, then unfastened her jeans and pulled those off as well. Tonya would have been worried about her brother returning soon, but for some reason it didn't seem like much of a concern. And anyway, she was wearing a camisole and panties, so it's not like she was completely naked or anything. As soon as her pants were gone, she felt her nose twitch, just as her brother's had.

Ahhh...That must be the scent he was talking about...,_she thought nervously. Tonya realized she had smelled it as well, just before she'd fainted. The smell was _definitely_coming from her. Looking down at her panties, she saw that the light blue fabric was a much darker shade of blue now. _How could I not have noticed this earlier?

The sixteen-year-old swung her legs back up onto the bed. Tentatively, she spread her legs apart and brought her hand between her legs. She touched a fingertip to her panties, and shivered. Her panties were soaking wet and slippery, but more than that, she'd felt an intense shock of pleasure just from that feather-light touch. Experimentally she touched again, harder this time, and began rubbing her fingertips in a tight circle. Tonya had to stifle a moan as the pleasure increased exponentially. At the same time, she felt the feverish temperature she was experiencing decrease a bit. The relief that brought was overwhelming to her.

Anxiously, Tonya looked at the door to her parents' bedroom. This didn't seem like the best time to be doing something like this, but Tony had been gone for almost five whole minutes. He might be having some difficulty in locating the book, and while he was gone, there surely wasn't anything wrong with indulging just a little bit, right? Tonya quickly tugged her panties off, stuffing them underneath the pillow. Shuffling herself down, she laid herself out on her back, resting her head comfortably. Whenever she masturbated, she preferred to go slow, taking her time and enjoying herself, but right now she was in a certain state of desperation. With that in mind, she spread her legs wide and put her hand back between them.

"Oh, god...," Tonya sighed as she put her fingers to her pussy. She was absolutely soaking wet, and her sex was hotter than she could ever remember it being. With no hesitation at all she slid a finger inside of herself, probing it around the confines of her tightness. Tonya knew all of the right places to touch by now, and she didn't waste any time in thrusting her finger deep. "Right...there..." With a stifled gasp, she twisted her finger around, curling it up and rubbing the top of her passage, where it felt slightly rougher than the rest. When she'd first found her g-spot, it was like opening a whole new world to herself, and once she got to this point during a normal session she never let up on it.

This time was no different. Tonya bore down with all the force she could manage in a single finger on the pleasure center, and she was rewarded with waves of sensation coursing up and down her spine. Her tail tip swished madly, the rest of it pinned down underneath her rump, and her pointed canine ears pricked up as the wonderful tingles grew greater. As turned on as she was, she knew from experience that it wouldn't take long to bring herself off. Even now, she could feel the familiar pulsing, the thudding of her own heartbeat that told her she was about to cum. More and more, harder, until finally...

Nothing.

"What?" Tonya almost shouted, before she clamped her mouth shut. Her breathing was heavy, and she felt a sinking, frustrated feeling as she realized she wasn't going to cum. "No, no, no, come back..." In desperation, she thrust another finger inside of herself to join the first, pressing deep against her g-spot to try to get it back. Though she was able to bring herself back to that heightened state of pleasure, she wasn't able to have an orgasm, even when she added a third and fourth finger.

By now, she was stretching herself almost to the point of pain, but the heated instinct inside of her body demanded that she continue. Taking a deep breath, the teen girl pulled her fingers out of her abused pussy, looking at the slickened fur. She'd only ever heard about what she was going to try now, but she was horny enough to try anything. Feeling a pang of guilt, though she really had nothing to feel guilty about, she pressed all five of her fingertips together, forming her hand into a spear shape. Spreading her legs as wide as she could, Tonya brought her hand back to her sex, and she pushed as hard as she could.

"Nnngh...Ahh...," she sighed huskily, trying to relax her pelvic muscles. Gradually, her fingers began to slide inside, stretching the tight ring of her pussy terribly. Tonya forced herself to keep going, knowing that she needed some relief soon or she'd go crazy. Now her fingers were inside up to the knuckles, until, with a quiet, wet pop, her whole fist was suddenly inside of her virgin pussy. Panting and wriggling her rear around as she tried to get used to the feeling, she managed a giddy little laugh. Can I really call myself a virgin after this? Maybe half a virgin...

Pushing that little philosophical question aside for the moment, Tonya tested out her novelty, twisting her fist around inside of her. She nearly fainted again at the pleasure it brought her, greater than anything she'd ever given herself before. Going for broke, she began fisting herself roughly, pistoning her arm in and out of herself. She could barely move it in her tight passage, but what little movement she was managing felt fantastic, almost as though something this size was supposed to be locked inside of her. And what's more, she knew that this time she was definitely going to cum. All she needed was just a minute more, and...

Suddenly her ears pricked up again, and she paused, panting. Footsteps were coming down the hall. With a start, she realized that it was Tony coming back. Panicking, she tried to tug her fist out, but it wouldn't budge. In her excitement her body was clamping down, and she didn't have the time to relax herself now. Thinking quickly, Tonya grabbed the covers with her free hand and threw them over her body, trying to act as though nothing was amiss. That task was going to be made difficult by the fact that her clothes were on the floor and her right hand was firmly lodged inside of her nethers, but if she acted natural maybe he wouldn't notice anything.

"Okay," Tony said, as he pushed open the door and walked inside. He had a thick, encyclopedia-like tome in his hands. "It took me a little while, but I finally found it wedged in between the almanacs and the..." He trailed off as he saw his sister lying on the bed. He was particularly struck by her lack of clothing, at least from the waist up, which was all that was visible. The German shepherd male's ears lowered a little in his confusion. "Did you take your clothes off?"

"Uh, yeah, um...it was just so hot, you know?" Tonya said awkwardly. She smiled, trying to dispel his concern. "Don't worry about it. I was just trying to get comfortable, that's all." She was painfully aware that her scent was stronger in the room than it had been before her brother had left, and there was no way that he wouldn't be able to smell it, too.

Though he didn't seem to accept her explanation, he could sense that she didn't want to talk about it further. Even though he was curious, Tony just shrugged it off and came back to the bed, sitting back down on the edge. Tonya did her best to shift her right elbow into a better position, and she winced as her fist rolled slightly inside her pussy.

"I'm not sure where to start with this book," Tony admitted, opening up to the index page. "Mom and dad always seemed to know what to do, though. Maybe we should just start where you noticed anything was wrong, and go from there?"

"Sounds good to me." While he was talking, Tonya was at work, trying to surreptitiously extract her hand from inside of her. As long as she didn't think too hard about how nice it felt to have her fingers rubbing around, she was able to relax, little by little. She almost had her wrist out. "W-Well, the first thing I noticed was I felt a little light-headed when I got up this morning."

Tony flipped the pages in the book's index, tracing a finger over the words. "That doesn't narrow it down too much. What else?"

Just a little more... Tonya had her jaw clenched, trying to keep from letting the pleasure show on her face. Her wrist bone was grinding right against her clit. "Ah...After that, when we were working with the cows, it started feeling really hot to me. I mean, more than normal."

"Okay, that helps a bit. Assuming you have smallpox." Tony frowned. "That's probably not it. Do you actually have a fever?" He put his hand out, laying it on his sister's forehead. "You seem warm, but not feverish..."

With a little huff of annoyance, Tonya pushed his hand away with hers. "Come on, is this really necessary?" She had her wrist out now, but she needed to move gingerly to keep from betraying anything to her brother.

"You know it is. We're a hundred miles from the nearest hospital. If this is something serious, we need to figure it out quick. What else have you been feeling?"

Tonya rolled her eyes, but she knew he was right. She just wished she had been able to think straight enough to pick a better time for fooling around with herself. As little as she was moving her hand, she was pretty damn close to cumming. "I felt fine after that until I was cleaning out the stable, and then I started feeling dizzy. I tried drinking some water, but my heart started beating so fast. I went outside, and it just felt even hotter. Then my legs got all shaky, and well...I fainted."

"Okay..." Tony flipped through a few more pages, then looked up at her. "Anything else?"

"No, that's about it." Tonya was easing her fingers out now. The German shepherdess was almost in free territory. "So? Does the book have any answers."

Frustrated, Tony closed the book, shaking his head. "Lots of possibilities, but I have no idea. I'm no doctor. How mom and dad ever used this book, I don't know. I better go call the hospital, get someone out here. Better safe than sorry." He got up from the bed, intending to head back to the kitchen and use the phone.

When he did, he just happened to jostle Tonya's right arm, the one which was just a hair's breadth away from being finally free from her pussy. Startled, she yanked reflexively, and her fingers slid the rest of the way out all at once. Tonya managed to stifle her scream, but she wasn't able to hold back the killer orgasm that rocketed its way through her body. As her brother turned and looked on in surprise and no small amount of concern, she started shaking violently, her thighs clenching together as overwhelming waves of delight washed over her. By the end of it, she was panting, her breasts heaving as she bit down hard on the knuckles of her left hand, doing whatever she could think of to try to calm herself down. Just as she had begun to wonder why it had grown so dark, she realized she'd shut her eyes tightly and opened them.

What she saw was Tony staring, his own eyes wide and his ears flat against his head. "Are you...Are you okay?" he asked, seeming not to know what else to say. His nose was twitching again. The strange scent coming from Tonya seemed to have increased tenfold.

"F-Fine...!" Tonya managed to gasp out, forcing herself to grow still. She met her brother's stare. When she locked eyes with him, all of a sudden she felt a jolt unlike anything else she'd ever felt before. Up until now, the female fur had been a little eager for him to get out of the room, both because of the awkward position she'd been in and because she felt silly having him wait on her like a servant. Now, though, when she looked at him she felt an overwhelming desire for him not to leave her, and she couldn't explain it. But she needed to say_something._ "Just had...uh...a headache. Just had a headache come up. That's all."

"A headache?" Tony repeated. He looked even more worried. "Must have been a bad headache for you to seize up like that...Now I _really_better call a doctor." He turned to leave again.

"No, wait...," Tonya pleaded. Her brain was starting to catch up with her body once more. She couldn't have Tony calling a doctor for her, especially not now. They really couldn't afford it, not this early in the season before the auctions had taken place. As embarrassing as it would be, she would have to level with him. A little bit, anyway. "Look, uh...I wasn't really all the way honest with you. There have been a few other symptoms."

Her brother stopped and faced her. "Oh, yeah? Like what?"

"Before I tell you, you gotta promise not to freak out, okay?"

"Freak out? Why would I freak out?"

"Just promise, will you?"

Tony was taken aback. There was an insistence in Tonya's voice that he hadn't heard before. She seemed like she was totally serious, and he found himself slightly curious in addition to the concern for his sister that he felt. "Okay, sure. I promise not to freak out. Now what other symptoms were you talking about?"

Swallowing on a suddenly dry throat, Tonya forced her ears to perk up from where they'd gone flat. "Okay. Okay." She took a deep breath. Best just to get it all over with. "Since about the time I passed out, I've been smelling this weird smell, and I think it's coming from me. I've also been really, really wet...down there."

Tony cocked an eye at her. "Down where?"

His twin sister let out an exasperated sigh. "Come on, Tony, you know what I mean. I mean down there." She gestured with her left hand in the general direction. "...My pus-...vagina."

Tony's face flushed warm, and his eyes flicked down involuntarily. Not much use in that, since his sister was under the covers. And why would I want to look anyway? he asked himself. "Oh," he said out loud. "Uh...I gotcha." The sixteen-year-old male tried to ignore the slight stiffening in his pants, and hoped it wouldn't be visible to his sister.

"And...well, I don't know if this is related or not, but...," Tonya said. "I've been thinking about stuff constantly since I woke up. Sex stuff. It's kinda freaking me out, honestly."

Clearing his throat, Tony opened the book back up. "Well, uh...let's have a look, then." He flipped through the pages once more. While he was looking, Tonya watched, more than once having to stop her right hand from drifting back between her legs under the sheets. She also realized that her eyes were drifting over her brother's form every now and again, and what's more she saw him do the same to her a few times, before he caught himself and focused his attention back on the book. A minute or so later, he looked back to Tonya, his face set. "I think I know why you've been feeling weird."

Relieved that she might finally be getting an answer, Tonya slumped back against the pillow. "Why?"

"You're not going to like it."

"Is it bad? Am I really sick, or something? I can't go to the hospital, I just can't, Tony." She was getting really worried now, almost as much as he seemed to have been before.

Tony rubbed the back of his neck with his hand. "Er...I wouldn't say it's bad, exactly. I mean...I guess it isn't good, but it's not anything wrong with you." He looked away from her. This wasn't the kind of thing that a brother hoped to have to discuss with his sister. Not for the first time in the past year, he wished his mom or dad were there, although it was for quite a different reason this time. "Uh...look, Tonya, I think you're in heat."

For a long, awkward moment, Tonya was just silent. Then she sat up in the bed fast enough to make her head start spinning again. "In heat?"

"I mean, that's the only thing that makes any sense," Tony pressed on. He stepped back to the side of the bed, holding the proper page up for her to see. "Physical weakness, fatigue, elevated body temperature, it's all here. When you add in the...ah...wetness and the thoughts you've been having, it's the only thing that makes any sense."

Still not wanting to believe it, Tonya shook her head. "But why did I faint?"

"Think about it," Tony said. "Your body was drained, devoting a lot of energy to being fertile. You were doing all the same chores that you normally would have. You passed out from exhaustion."

"This doesn't make any sense," Tonya insisted, although she was starting to realize that it had to be the truth. She'd had the talk from her mother years ago, after all, so she was perfectly familiar with the concept of being in heat. Farm girls, growing up around horses and cows that bred all the time, tended to find out these things on their own, even if she hadn't had her mother to tell her. She just hadn't expected for it to happen now, of all times. "I'm only sixteen! Mom told me that she didn't have her first heat until she was almost twenty. She said Aunt Nancy and Aunt Claire got theirs around the same age. I'm not old enough yet!"

Tony tapped the page. "It's the right time of year. The book says right here that most females go into heat twice a year, late spring and mid-fall." He turned the book back around, reading a little more. "And not everyone is the same. You might be an early bloomer. A few years early isn't all that much, you know."

"Oh,god, this is so embarrassing...," Tonya said, covering her face with her hand. A moment later, she let out a sharp laugh that was more rueful than amused. "I guess that smell we were both smelling makes sense. Now I know what it's like to be one of the mares."

"Y-Yeah," Tony said, his eyes widening a bit. He hadn't thought about that. The stallions went absolutely crazy whenever one of the mares was in season, and it stood to reason that German shepherds like he and his sister wouldn't be much different in that respect. This could be very bad.

Tonya looked up at him, her expression anxious. "So...So how long am I going to be like this? A few days? Will I be better tomorrow?"

She was leaning towards him, and Tony found himself leaning away. He suddenly had a really bad feeling. "Uh...I don't think so. It says here it could last anywhere from a week to several weeks, depending on how old you are. I guess the younger you are, the longer it's supposed to last..."

"I'm gonna be like this for weeks!?" Tonya exclaimed. Irrationally, she lifted her right hand out from under the covers for him to see. The fur on her fingers was still slick and matted from her illicit masturbation session. "Tony, I can't deal with this for weeks. There's work to be done around the farm, not to mention the fact that I am already half-insane from horniness."

"What do you want me to do about it?" Tony asked helplessly. "You're just going to have to take it easy until you start to feel better. And..." He hesitated. She especially wouldn't like this. "I think we should spend as much time apart as possible. I mean...look, that scent is getting really strong already, and it sounds like you've been in heat less than a day. It's only going to get worse. No reason to tempt fate, right?"

Now it was Tonya's turn to feel her face flush. At those words, some images that she really didn't want to see were flashing through her head. All at once, she was imagining her brother moving closer to her, pulling the covers off of the bed, and climbing up on top of her. Except, of course, he would pause a moment to take his own clothes off. Then he'd push her legs apart, thrusting into her with his hard, throbbing-

"Fuck...," Tonya cursed in a mumble, flopping down on the bed. She was so goddamned horny that she was fantasizing about her brother mating her. "I think you might be right..."

Tony nodded. "I can go finish cleaning out the stables, and then I'll bring the horses in for the evening. There's not much left to do today. Get some rest and then tomorrow at breakfast we can figure out how to divvy up the chores so we're separate during the day." He managed a smile. "We'll get you through this, okay, Tonya?"

"Sure," she grumbled. But she forced herself to smile back at him. "Thanks." Her brother nodded again and then walked out, closing the door all the way this time. She heaved a huge sigh when he was gone. It had taken a good measure of her willpower not to ask him to stay a little longer when he was leaving, and she had no illusions about what that very likely might have led to. The scent that a female German shepherd gave out during heat was quite specifically designed to make any male German shepherd in range want nothing more than to have sex with her, and she knew that her body wouldn't discriminate too much as far as its criteria went. If Tony was wired appropriately, he'd definitely screw her if given the chance, so he was right that physical separation was the best way to deal with this.

But that didn't mean that it was going to be easy. As Tonya slid out from underneath the covers, another hot flash passing through her body, she couldn't stop herself from starting to think about what she'd been imagining before. And those thoughts of her brother didn't subside, even as she succumbed to her heat-driven urges and began to stroke her swollen pussy once more.

******

Over the next few days, Tony tried to grow accustomed to being separated from his twin sister during their daily lives on the ranch. The first morning, he managed to sit down with Tonya for an hour at breakfast so they could work out a schedule of chores together. Tony wound up with most of the work, since they both knew that Tonya was going to be getting tired a lot more easily than she normally would have. His sister got the lighter tasks, such as the cooking, milking, and tending to the chickens. Until she was over her heat, Tony would have to mind the ranch fence, fill the water troughs, feed and exercise the horses, and clean out the stables all by himself. This left precious little time for him to do much else except go to bed and wake up again. However, it did accomplish the task of keeping them apart, though they did eat their meals together. That was about as much as they could manage before instinct began threatening to take over.

Tony found the whole thing excruciating. When he was away from his sister, he was fine and could keep a clear head. But when they got together, the air became thick with the scent of her heat. He wasn't blind. He knew that his sister was attractive. Tonya had what he would consider a nice body. She was shorter than him, but she weighed about the same, so she was pleasantly curved in all the right places. The German shepherd fur had decent breasts, for a sixteen-year-old anyway, and he had to consciously force himself to stop staring at them now, whereas just a few days earlier he wouldn't have even dreamed about looking. She was his sister, after all. Even so, after about thirty minutes of sitting at the same table with her, his cock was straining at the seams of his jeans.

He could tell that she was having just as much trouble, and more. Tony, after all, did not have the same biological imperative that his sister had. When things got to be too much for him, he could find an excuse to go off by himself and jerk off, and the urges would be gone for eight hours or more. Tonya wasn't so lucky. She could masturbate as much as she wanted, and cum over and over again, but her body would not stop demanding more until she was properly mated by a real male. In all actuality, only getting pregnant would really stop it for good, unless she managed to make it all the way through the few weeks. Then, mercifully, her body would return to normal and she would be back to her old self. At least until the spring, when it would all start again.

That was what really scared the two of them. They could concentrate on the matter at hand and it seemed like a simple thing to overcome, but in the backs of their heads they both knew that things would never be the same. Now that Tonya had had her first heat, they had about twenty years of this struggle to look forward to, assuming they both stayed on the ranch. Sure, they'd probably get used to it after a while, but how long would that take? Could they both resist their base instincts long enough to where it wouldn't be that big of a deal? Even with as much effort as they were putting forth, Tony could tell that Tonya was getting more flirty with him as the days went on. Whenever he walked by her room, he could smell her, and he could also hear her moans and whimpers as she pleasured herself. As the days went on she sometimes neglected to close her door all the way. His eyes would be drawn to the gap between door and door frame, and he'd be able to see her on the bed. Never clearly enough to make out the details of her increasingly enticing body, but enough so that his curiosity was piqued. Tonya was never looking towards him, and so he truly believed that she honestly wasn't doing it on purpose, but it was still enough that several times he stopped, guiltily spying on his twin sister as she rubbed herself furiously between her legs.

It was on one of these occasions, when he was walking by, that something different happened. Five days had passed since she had first gone into heat, and Tony could tell that Tonya was getting desperate. That day she had dressed even more casually than she had been before, wearing shorts instead of long pants and a t-shirt instead of a long-sleeve shirt. He knew from reading the home health book that Tonya would be feeling hotter than normal, so it stood to reason that she'd want to wear shorter clothes, but it definitely did not help their situation. Whenever he'd gotten the chance that day he'd quite openly ogled her, and she had done the same to him. They hadn't eaten dinner together. Tony was on the way back from the bathroom, dressed for bed and having just finished brushing his teeth, when he heard the usual sounds from his sister's bedroom. Feeling that pang of guilt, he stopped and looked inside.

Tonya was on her bed, also dressed in her pajamas, but this time she was facing the door. Luckily she had her eyes closed, but she was on her belly and she had her rear end raised in the air. Tony could tell from the way she was moving, waving her ass from side to side and clutching at the sheets with her left hand, that she had her right hand down the front of her pajama bottoms and was playing with her pussy. He bit his lip. Her scent was as strong as ever, and she looked so sexy the way she was acting. Without even realizing what he was doing, he was fumbling with the button at the fly of his pajamas, and a second later his cock was out. The thought of what would happen if Tonya should see was far from his mind. All of a sudden he was horny, hard, and in need of release.

Wrapping his fingers lightly around his thick canine member, he started stroking himself slowly. Just being in the same house as a female in the peak of estrus kept him in a nearly perpetual state of arousal; lingering outside her door had him harder than he could ever remember being. As he toyed with himself, he inhaled deeply, filling his lungs and letting Tonya's aroma take him over. He knew this was absolutely wrong, but he couldn't help it. She was the most intoxicating thing he had ever experienced in his life. He watched her through the crack in the door, listening to her quiet moans. His sister's tail was wagging back and forth rapidly, mirroring the movements of his own. Tony started panting, his long tongue protruding from his mouth as his mind clouded up from the influence of her pheromones.

Closing his eyes, Tony focused on the sensations of his hand on his rigid cock. His fist began moving faster along his length, and he gripped tighter. He began picturing what it might look like if Tonya was in the same position as she was now, only nude rather than in her pajamas. Though he didn't know exactly what his twin sister looked like naked, his imagination didn't have much trouble filling in the blanks. His addled brain took it one step further, inserting himself behind Tonya, his hands wrapped around her waist as he thrust into her. A pleasurable twinge shot through his cock at that thought, and a low groan escaped his lips without his meaning to make a sound.

"Tony?"

Tony's eyes shot back open, and he froze in place. He was met by the sight of his sister standing at her door, looking out at him. She seemed just as surprised as he was mortified. Hurriedly he thrust his cock back inside his pajama bottoms, stifling a yelp of pain as it was bent in a slightly improper direction. When he was suitably modest again, he struggled with what he should say. He felt like he should apologize, but he wasn't sure where to start since he was most certainly guilty of several offenses, least of all fantasizing about her.

"Uh, I was just walking by and...," he stammered, trying to think of some excuse. The German shepherd was having difficulty thinking of much of anything right now. The button-up top of Tonya's pajamas was oversized and hanging off one shoulder, and her cleavage was visible. He wanted to slap himself. "I mean, I was just checking on you. Didn't really see you all day."

"I thought that was the point," Tonya replied. He saw her eyes flick down, and he followed her gaze. His erection was clearly visible as a bulge in the crotch of his pants. "You looked like you were doing a little more than just checking on me."

"Well...ah...I can explain..."

She shrugged. "I can't really blame you," she said. "I was kind of doing the same thing." Her voice was fairly breathy and shaky, and Tony felt a jolt up his spine as he realized she was staring at him with a hungry expression. Her mouth was barely open, a sliver of the pearly white color of her sharp canine teeth contrasting with the black and tan fur of her muzzle, and her brown eyes had an intensity about them that made her face scarcely recognizable. She had it bad. "You could have just knocked and asked to watch. I wouldn't mind."

The starkness of what she had said injected a little sense into Tony. He shook his head hard, looking away from the female fur. "You're just saying that because you're in heat, Tonya," he said. "You're my sister. I couldn't do that. I shouldn't even have done what I already did. I let your scent get the better of me."

"You didn't have any problem doing it when you thought I didn't know you were watching," Tonya pointed out. But his words seemed to have a little bit of an effect on her. "I guess you're right though." She got an almost hopeful look on her face. "Can you at least come in for a minute to chat? I feel like we haven't seen each other for years. It's starting to feel kind of lonely."

Tony hesitated. He felt the same way as Tonya, but he wasn't sure how much they were both being influenced by her condition. Still, he reasoned, what could a few minutes of chatting hurt? "Just a minute," he allowed. "And even that's probably not a good idea, but...yeah, I'll admit, it has been a drag not being able to be together."

Smiling at him, Tonya stepped aside from her bedroom door and opened it more, letting him in. Tony went into her bedroom, going to her bed and sitting down on it. She closed the door and joined him, sitting down a few feet away from him. For a second or two they didn't say anything. Both of their hearts were pounding as they considered what to do next. Now that they'd made the decision to break their vow of seclusion, they were at a loss.

"So...uh...," Tonya said, breaking the silence. "I've been working near the dairy and the house the last few days. How's everything on the rest of the ranch?"

"Fine," Tony said quickly. He finally met her eyes after trying to look anywhere else. While the expression he'd seen before had softened, it had not vanished completely. "Two more of the cows out in the pasture are pregnant. I've been thinking I might want to move the bulls to the secondary enclosure. Need to make sure that we don't have more calves than we can handle come spring."

His twin nodded. "Yeah. You know those bulls. They'd have as many kids as they could if we let them." She fumbled with her hands, and he noticed they'd been straying towards her waistband. He tried not to think about it. "How are the horses? I've missed being able to ride."

"They're fine, too." Tony laughed a little. "I think the mares miss you. Whenever I come in to the stable, they look at the door like they're expecting someone else to come in behind me."

Tonya laughed as well, her bushy tail wagging, and she slid a little bit closer to him on the bed. "That sounds like them. They are kind of attached to me." She traced a finger in a circle on the bedspread, digging a faint crease into the fabric. "And, um...how have you been? Build any new models lately?"

"Haven't had much time for that," Tony replied. He was watching his sister carefully. God, but she's beautiful..."I've been a lot busier than normal. I have been working on a boat model, here and there when I have a few minutes free. Popsicle sticks this time."

"Can't wait to see it, when it's done." Tonya glanced down at the floor, then back at her brother, sliding another few inches closer as she did. "I meant to say...The other day when you showed me that model of the Empire State Building? I was rude when you showed it to me. It was actually really, really cool. I like your models, and you're really good at building them."

Tony blinked. "Thanks! I worked a long time on that one. I was hoping it looked alright." He grinned sheepishly, forgetting for a moment his need to separate from his sister. They'd already been in the same room together for a lot longer than was prudent. "I didn't realize you liked my stuff. I always thought that you thought they were dorky."

"I do," Tonya said. She was right next to him now, their hips almost touching. He could feel her tail brushing up against his as it waved back and forth behind her back, and every time it made a little thrill rise up in his chest. He wanted her to twist their tails together. "I mean, I did, but..." She swallowed, her throat bobbing as her voice got a little quieter. "Mom and dad always encouraged you with your hobby, and now they're gone, so...so I feel like I need to keep the tradition alive."

Tony felt a lump rising in his throat. "I had no idea you felt that way." He reached over and put a hand on Tonya's shoulder, bared by how her top had slid away. Her nut-brown fur felt incredibly soft underneath the pads of his fingers. "You don't show it, but you still miss them a lot, don't you?"

"I miss them so much," Tonya admitted. Now their hips were touching, and she'd placed a hand on his leg. She was rubbing her palm slowly back and forth over his thigh. It felt really nice. "The last year has been so hard, but I try to keep strong. Working on the ranch helps, but since I've had to start taking it easy, there's more time to think." Her voice broke a little. "That's why it's been so difficult to have to keep away from you. It sucks."

Now Tony wasn't sure at all what to do. He knew it was about time that he should be leaving his sister, but to leave her like this, when she was depressed from thinking about their dead parents...That seemed rather heartless. Trying to comfort her, he squeezed her shoulder. "Listen, it'll only be for a little while longer. Then everything will be back to normal."

"Until the next time I go into heat," Tonya grumbled. She sighed, and rested her head on his shoulder. "You have no idea what this is like. It's hell. I can't keep my hands off of myself, and I feel hot all the time..." She looked up at her brother. "You wouldn't believe how wet I am. I have to change panties about every five hours."

Now it was Tony's turn to swallow. "You don't say. That's, uh...That's interesting to know." Without really noticing what he was doing, his nose touched the top of his sister's head, nuzzling between her pointed ears. "Sounds bad."

"Real bad." Tonya lifted her head up, turning her face so that the side of her muzzle brushed against his. She was panting slightly. "I wish there was something we could do about it."

Tony knew that things were going beyond his control, but he couldn't quite muster the effort to care too much. His cock, which had been straining at the button of his pajamas ever since Tonya touched his leg, was starting to override his brain. "We really shouldn't."

"I know we shouldn't, but do me a favor right now, Tony," Tonya said, her voice lowering into the register of a throaty growl. She pulled her head back enough to look into his eyes. "Just shut up." Then she leaned in to him.

Before Tony was completely aware of what was happening, the German shepherd twins had their muzzles locked together in a deep, intense kiss. Tonya slipped her tongue deftly into his mouth and turned her body so that her breasts were pressed against his chest, and her arms came around him in a hug. Instinctively, he hugged her back, groaning quietly in surrender as he returned her kiss. The sixteen-year-old felt like the burden of the last few days had been lifted completely from his shoulders. Thinking of the girl he was kissing as his sister anymore was impossible. Right now, all his body knew was that there was a female in the throes of heat nearby, and her scent was overpowering. He was painfully aroused, and she was receptive, and for the moment that was all that mattered.

"Oh, god...," Tonya groaned, breaking the kiss and gasping for breath. She whimpered the next words, sounding truly remorseful. "I hate myself right now. But I don't fucking care anymore, I just don't care."

Tonya slid off of the bed, sinking down to her knees in front of Tony. He watched her with a sort of detached fascination, like he was outside himself viewing what was going on. His sister fumbled with the button on his pants, unfastening it and darting her hand inside. They both gave a moan as her slender fingers touched his shaft. She wrapped around him, tugging gently and freeing his cock from its confines. Tony gulped as she looked at his canine member. He was completely erect, his length at its full size, although his knot was still concealed within his sheath. His tip jerked with each pulse of his heartbeat, which was increasing rapidly.

"Tonya, we...," he whispered, fighting hard to come up with the words. "We really shouldn't be doing this." Tony couldn't tear his eyes away from her as she leaned in closer to him. He could feel the warmth of her breath on the red, exposed flesh of his cock. "This is bad."

"I don't care," Tonya repeated. She touched the tip of her nose to him, her nostrils twitching as she sniffed. A shiver passed through her body as she detected his musky scent, not dissimilar to the smell her heat was producing. "You can judge me when we're done."

With that, she opened her mouth and took him inside of her muzzle, and all objections he might have been ready to make next died as soon as he felt the velvety bliss of her tongue. Tony gave a rough growl instead, tilting his head up as his ears swept back low. His sister murmured around him, sliding her lips down his shaft until the slender pointed tip was just tickling her throat. For a moment she just held him there, gently rolling her flat, wide tongue along the underside of his cock. Then she moved back again, keeping her lips sealed tight until she came up to the top. Tony whined softly as a thin stream of precum left his cock and bathed the roof of her mouth. When she tasted it, her tail started wagging madly and she flicked her tongue hard against him.

"Dammit, Tonya...," Tony said. She looked up at his face, pure unadulterated instinctual lust in her eyes, and then she pushed her head down again. Tony laid a hand on top of her head, stroking the black fur there and rubbing behind her ears. Her tail wagged harder. What she was doing felt incredible, and he was caring less and less that the first blowjob he'd ever had in his life was coming from his sister.

After only a few minutes of this treatment, Tonya abruptly stopped. With a final stroke of her tongue as she slid her muzzle off of his cock, she sat up on her haunches. Surprised, and a little annoyed at the sudden stop, Tony looked down at her. He could see a curious expression on her canine face, as her brown eyes stared into his identical brown eyes. As he watched, she hooked her fingers into the elastic waistband of his pajama bottoms and dragged them down his legs. He bit back a moan of pleasure as the fabric dragged over his cock. Tonya left his pants where they dropped to the floor, and then she stood up, unbuttoning his shirt. Her movements were growing quicker, and one of her claws snagged a button, ripping it off by accident.

"What are you doing?" Tony asked her, though he didn't make any effort to stop her.

"Can't wait any more," Tonya said simply. She pushed his shirt off of his shoulders, coming around his back to pull it off his arms. When his clothes were gone, she got up from the bed and stood in front of him. As Tony looked on, his heart pounding hard enough that he thought it might hammer through his chest, she made quick work of stripping off her pajamas.

Tony's breathing seemed to stop as he finally gazed upon his naked sister. Her black-and-brown fur coat was sleek and glossy, though slightly ruffled in a few places. The sixteen-year-old female was curvy, with wide hips that tapered up into a slender waist. As Tony's eyes traveled up her body, he realized that he had never noticed how well-endowed she was. Her breasts were larger than one would be able to tell from the clothes she normally wore, full and perky with her youth. He also noticed that she had the exact same streak of lighter tan coloring down the middle of her chest that he had. She was a gorgeous young woman.

And now that she was unclothed, and they were alone in the confined space of her room, the scent of her heat was absolutely intoxicating. Tony's tail started wagging eagerly as his body recognized what was about to happen.

"Tonya..."

"Shh," Tonya hushed him, leaning forward and putting a finger over his lips. She crawled up onto the bed next to him, going on all fours up to the head of the bed. Glancing back at him, she bent over at the waist, laying her head down on the pillows. Her bushy tail curled up over her back, exposing her hindquarters. Her pussy, dark lips swollen with need, was absolutely dripping wet. Tony could just see pinkness hidden within. Just above he saw the small pucker of her ass, ringed by thin, light tan fur. The sight was enticing, the most inviting thing he had ever laid eyes on.

Tony turned around on the bed, pulling his legs up. His cock was engorged now, his knot starting to push out of his sheath. Every instinct he had was telling him to mount his sister, to push his shaft inside and fuck her like his life depended on it. But even now, he still had a shred of his senses about him. He hesitated.

Tonya stared at him expectantly. "Come on, Tony, hurry up...You gotta do it, I can't take it anymore!"

Tony swallowed, staring at the sight that was right in front of him. Her heat-inflamed, soaking wet pussy glistened in the soft light from her bedroom lamp. Her scent was incredible, the most delicious thing he had ever smelled, and his heart was fluttering as he let it fill his nostrils.

His twin sister was staring back at him now, desperation painted across her black-and-tan-furred face. "Tony, please!" She grabbed fistfuls of the sheets, and she swayed her ass tantalizingly from side to side.

The male German shepherd's eyes followed her rump, and he bit his lip. "Look, Tonya, I know you're in a bad way right now, but we really shouldn't-"

"I don't care anymore!" Tonya blurted out, looking furious and frustrated enough that Tony was almost afraid she would burst into tears right then and there. Her nails dug into the sheets, ripping small holes in the fabric. "You don't know what this is like! I can't handle it for a second longer. You have to help me, you just have to!"

Looking away, Tony swallowed again, trying to gather his thoughts. His nose was full of the scent of the girl begging him to fuck her, making that task very difficult indeed. As much as his body really, really wanted him to agree to what she was asking of him, the rational part of his mind knew that mating a female in heat was not the greatest idea in the world for a sixteen-year-old who hadn't planned on fathering kids this early in life. And that was beside the fact that the female in question happened to be his twin sister...

"Tony, please...," his sister begged, whimpering now. His heart almost broke as he heard the sheer desperation in her voice. "I'll never ask you for anything ever again as long as I live. I know it's wrong. I know it's dangerous, but this is torture. I'm asking you because you're my brother, and I need your help. Please..." Her voice quieted to a whisper. Tony could tell she was ashamed of herself. "Please fuck me, Tony..."

He rubbed his face with one hand. When his sister put it that way, would it really be so wrong? For almost a whole week she had been struggling to hold back something she was entirely unused to, and she had reached her breaking point.

Tony came to his decision. Sitting up on his knees he shuffled over to Tonya. He laid a slightly trembling hand on her back, stroking along her spine. She closed her eyes, moving her rear back and forth. Her rump touched his hip, and she whined quietly, but her grip on the sheets relaxed a bit. He just petted her for a few minutes, scratching between her shoulder blades lightly until her breathing quieted and she calmed down a little. Leaning down, he kissed her on the cheek. Her face was damp. She had been crying silently while he rubbed her back.

"Alright," he said. Tony tweaked one of Tonya's ears. He moved behind her, putting his hands in a grip on her waist. She gave a whimpered sigh of relief. "If you really want me to, I'll help you."

Tony took his cock in one hand, holding himself steady as he lined up with his sister's pussy. She growled a little as he slowly prodded the tip just between her lips, and he pushed just barely inside of her. Then he renewed his grip around her waist, taking a deep breath. He figured it was best just to do it quickly. With a hard push forward, Tony plunged his cock inside of his sister's heated cunt. They both howled loudly as he speared her virgin body, and Tony shuddered as he hunched over her back. She was fiery hot inside, her heat stoked by days of fruitless self-service. Now she had a real male inside of her, and her body was unleashing that fire on him.

Tonya pressed back against her brother, forcing him deeper into her until his knot was kissing her outer lips. He took it as a sign that she was not interested in tenderness or further foreplay. She was in need of a hard, fast mating, and he was surrendering to her demands to give it to her. Holding on firmly to her, Tony began thrusting his cock in and out of his twin, quickly building to a fast tempo of fucking. He found it hard to believe how tight she was, but she was like a velvet vice clamped down on his malehood. The pleasure was unimaginable.

"God, Tonya...," he groaned, tightening his grip on her waist. He pounded her swollen pussy, forcing his knot hard against her clit with each inward thrust. His sister rocked back and forth in time with his movements, her tail flopping back and forth in his face as he fucked her. "You feel so good inside..."

"Don't talk...," Tonya whined, hugging her pillow to her face. She buried her muzzle in the soft, downy surface, muffling her voice as her moans turned into screams. "D-Don't talk, just fuck me!" Her body was experiencing something that she'd never felt before in her life. For these past few days, she'd felt an overwhelming sense of emptiness, like something was missing within her. Now that her brother was behind her, his cock inside of her hot sex, she felt like she was being filled in more ways than one. The fire within her was starting to die down, but she knew she needed something more before it was extinguished completely. Feverishly she forced herself back harder against him, knowing that she needed him fully within her.

Tony could tell what she was trying to do. The rational part of his mind would have told him that he shouldn't, but then a lot of things had happened tonight that shouldn't have. But this was different. If he knotted his sister, there was a very real chance, more likely than not, that she would get pregnant. He wasn't sure he was ready to be a father, least of all with his twin sister. The safe thing would be to pull out before he came, but...when it came right down to it, safety had been off the table as soon as he'd agreed to come into Tonya's room.

With a grunt of exertion, Tony drew his hips back all the way, nearly unseating himself from inside of his sister's sex. As hard as he could manage, he slammed forward into her, and she gave a startled yip of pain and surprise as his knot was forced halfway, not all the way, inside. Trying again, Tony pulled his hips back, slamming forward again before she could recover. This time he was successful, and they howled again as his knot went inside of her pussy, tying them together. Nearly at his peak, he laid down against her back, his thrusts becoming short and fast as he humped her frantically. Tony opened his canine mouth and bit down on the back of her neck, snarling as he lost all sense of control.

Driven mad by lust, Tonya held herself still, giving herself over to her brother and letting him fuck her like a wild dog. In a few seconds she felt the sensation rise up inside of her, stronger than it had ever been in her life. Pushing up on her arms, she tilted her head towards the ceiling, letting lose with a wolf-like howl that threatened to rattle her bedroom window out of the frame. Then she slumped down to the pillows once more, panting and gasping for breath as her body was rocked by her brother's continued movement.

Moments later, Tony gave a sharp bark, thrusting a few more times before pushing as deep as he could and holding himself there. The tapered tip of his cock nestled just at the opening of Tonya's womb, and he shuddered hard as his cock began pulsing his seed into his sister. She was as fertile as a female could be, and he as much as a male could be, but he simply did not care anymore. He held onto her tightly, teething at her neck as he flooded her body with cum. When the flow finally ceased, he gasped, weariness taking him over. He realized he didn't have the strength anymore to hold himself up, and he let himself down as gently as he could. Tonya's rear came down with him until he was resting fully on her back, while she was on her stomach flat on the bed.

Gingerly, avoiding tugging to hard on his cock lodged firmly within her, he rolled them onto their right sides. Tony moved his arms up around her chest, hugging around her breasts from behind. They were both exhausted, but the relief in the room was almost palpable. Tonya was still slightly feverish, but the heat was mostly gone, extinguished by the seed of her brother. Suddenly tired beyond belief, they both began to drift out of consciousness.

As sleep overtook him, the last thing Tony remembered hearing was his sister's whispered words of "Thank you..."

******

Hours later, Tony heard his sister's voice again, rousing him from a deep and dreamless sleep.

"Tony...Hey, Tony, wake up..."

Mumbling pleasantly, the German shepherd fur opened his eyes, blinking a few times to clear the haziness out of his vision. He was lying on his back, looking up at the ceiling, and Tonya wasn't in his arms any more. While he'd been asleep, his knot must have shrunk enough to let her detach from him. Curiously, though, he still felt a weight down around his waist. Yawning, he looked down along his body.

Tonya was looking back at him, her hands braced against his lower belly as she straddled him, her hips connected with his. She had an impish grin on her face, and her hips were moving about in a slow circle. Tony groaned as he realized that, though his knot might not be stuck, he was definitely still inside of her. She seemed even tighter than before.

"Morning, sleepyhead," she said, her voice a sultry moan. "I didn't think you would wake up, even for this." Tonya wagged her tail, and he felt her clench around his cock, which was every bit as hard as it had been earlier.

"Morning?" Tony asked. He turned his head to the side. Though it seemed early, he could see light through the bedroom window. "Well, morning it is." He looked back at his sister, unable to keep an amused smile off his face. "And, uh, what do you think you're doing?" His hands came up, resting on her thighs and ruffling the soft fur there.

Sighing, Tonya leaned over him. Her breasts swung appealing near his face. "Oh, you just looked so cute laying there. I thought I'd give you something nice to wake up to."

"What happened to 'just one time'?"

She smirked at him. "I figure, when you've done it once what's the harm in doing it again?" Tonya kissed him, brushing her hand over his ears and along the side of his muzzle. "I can't thank you enough...I feel loads better, now."

"Still horny, though, I see." Tony kissed her in return, pushing his hips up lightly, making her gasp as his cock slipped a little deeper inside.

"Well, yeah..." Tonya sat up, leaning back and propping herself up with her hands on the bed behind her. Looking down between them, Tony got the shock of his life when he saw that his cock was not in her pussy, but rather being hugged snugly by the tight ring of her ass. "And I thought we could try the other thing. As long as we're being depraved and all."

Tony's head spun with how naughty his sister was being. "You're so bad," he groaned. "You realize you're probably already pregnant right now, don't you?"

"I'm not in heat anymore, so I think we can both assume that I'm definitely pregnant." From what he could tell, Tonya didn't seem too disturbed by that. Neither was he, now that he thought about it. "I didn't hear you complain last night, too much." Smiling wider, the female fur lifted up, and his cock slid out of her ass halfway. She pushed back down, and they both groaned as he slid back inside, stretching her tailhole with his thick length. "Nothing we can do about it now. Might as well just make the best of it."

"Good point." Tony reached down between her legs, digging his thumb into her slit. She gave a pleasured whine, her ass squeezing his cock as he rubbed hard against her button. She gazed at him with half-lidded eyes, her tongue hanging out as she began fucking him, slowly and steadily. "If this is how life is going to be from now on, we might as well do it right."

He rolled her over then, making her scream as he drove himself fully into her ass. The sun climbed higher outside, but it was a long time indeed before they paid any mind to the chores that had to be done.
