A brood mare's first heat is never easy- but Sussie's might just be the worst.


Hello, world! Smilecat here. My many days of lurking are over, and here's what I have to show for it. I'm very new to posting here, so any reader's thoughts are much appreciated. Please enjoy!


Slam!

Sussie hadn't been sure what life would be like once she came into season, but now she was certain of one thing- Being in heat sucked. Just last week, she had been having a wonderful time trotting around the farm yard with her older brother Todd. And now she was locked in a stable all alone, with no chance of seeing her brother, or any of her friends, for weeks!

It wasn't fair. Now that her brother was a serious dressage competitor Sussie hardly ever got to see him, and she'd been so excited to finally spend time together. They'd had a lovely day of catching up on old times, shared a giggle at the foals-versus-fillies games they used to play as kids, and reveled in the normalcy of just having each other's company.

It really had been a wonderful day. And Sussie was sure that if it hadn't been for that horrible old farm donkey, she would have had a wonderful week. Upon returning to the barn, she and her brother had the bright idea to visit Seymour, a blind old farm donkey who'd been like a grandfather to them as ponies. He was quite senile at this point, and rarely noticed the company of others, let alone asked for it. But Toddy thought it would be nice to visit him for old times sake, and Sussie thought it was a nice idea too.

But boy, was she wrong! Upon approaching him, Seymour began to sniff the air wildly, as if something delicious was nearby. Sussie thought perhaps it was another one of the senile old donkey's odd mannerisms, and thought nothing of it. She and her brother said hello, and Seymour gave a mumbling hello back, still sniffing. Sussie thought maybe the blind donkey was trying to figure out who they were through sense of smell alone.

Suddenly the old farm donkey leaped on top of her, pinning Sussie down with his full weight against her hips. It took a moment for her to realize that the old fool was actually trying to mount her! His semi erect penis flopped uselessly against her flank as she tried to get away. Toddy quickly knocked the old donkey away from his sister before anything serious could happen, but not before the scene caught the attention of a few ranch hands. Luckily no harm had been done (aside from mortifying embarrassment on everyone's part.) But the ranchers seemed terribly concerned, and acted accordingly.

Now Sussie was safely locked away in an all-females stable, far from any potential mate. It didn't seem fair at all to her, though. If anyone should be locked away, she thought, it's that dumb senile old farm donkey, not me! Now she was stuck in the stables for god knows how long, doomed to live out her days with no one but the other mares to keep her company. She was miserable.

But life in the mares stable had it's benefits. Sussie was curious to know who she would be actually be bred with, and the broodmares were happy to tell her. Another painted stallion named Bishop, 4 years her senior, had been rented for a 3-month engagement by Carro Ranch based on his incredible race record. During this time he was expected to give Sussie and a few other young mares his prize winning offspring. As far as horses go, she could do worse than a race champion, so that was fortunate.

However while she was glad to hear more about the mysterious stallion who would take her virginity, most of the details the older mares chose to share with her weren't nearly as interesting. Her stablemates only seemed interested in two things: Themselves, which was horribly boring, and breeding- who they had bred with, who they would breed with, and who they wanted to breed with. The older mares reveled in saucy retellings of breedings past, but they kind of grossed the young mare out. Aside from talking about Bishop, she mostly tuned her stablemates out.

At first Sussie was upset at not being able to pick her mate, but then again, it wasn't like she was a wild horse with a whole pack of stallions to pick from. There certainly weren't any other stallions at the ranch she cared for, and according to the other mares Bishop was quite a lover.

So Sussie waited, and she grew used to the life of a broodmare.

In the all-female stables, there was no one so popular as a girl who had just been bred, giddy with exhaustion and relief, with the smell of stallion sweat radiating off of her so thickly that all the stable air was wet and heavy with heat. Whenever a broodmare returned from a breeding, she couldn't help but babble about her experience to everyone. All the sex-addled girls could talk about was the pleasure of having taken a stallions seed and how his cock had felt inside her. The other broodmares lapped up every saucy detail. Sussie knew she'd soon be one of those heat-addled girls and looked to her own breeding with trepidation. The just-bred mares dazed expressions, and the brazen desires they expressed, embarrassed Sussie. Would she really become just like them after Bishop had his way with her?

But maybe it was boredom, or maybe it was just the way heat affected her brain, but but as the days progressed she found herself more understanding of their desires. After a week in the females stable Sussie realized that she really did want to be bred by Bishop. It seemed lucky that a stallion as strong as him would be the father of her first foal, she thought. Sometimes she even felt envious of the mares who had been claimed before her.

She still missed talking to her brother, of course, and she fervently hoped she'd be able to spend at least a little more time with him before he went off to compete. But as the days progressed, Sussie grew to be thankful for the handler's wisdom in separating her from the others. The strange feelings in her gut were more persistent and harder to ignore with each passing day, her occasional wet dreams more frequent and vivid. Even her idle daydreams were explicit now- and much harder to shake. These were all things she had no interest in talking to her brother about, but they filled her mind constantly. She had little interest in sharing them with the stable mares either, but at least her living situation allowed her the privacy to indulge those thoughts in daydreams... without fear of being interrupted just as she got to the 'good part.' It got to the point where there wasn't much Sussie wanted to do besides daydream and occasionally pleasure herself.

Sussie had heard that sometimes, when the heat-itch was so bad, and waiting for their breeding time seemed impossible, the mares would service themselves... and each other. They'd use their long, soft tongues- softer than a male organ, but still strong enough to push deep into a needy pussy- and lick and lick until their itch was satisfied. It wasn't much talked about, but it wasn't exactly a secret, either- just something that the mares did in the dark, when they needed it, when they couldn't stand the heat. Sussie had no desire to experience it herself; The idea of putting her mouth to another mare's pussy disgusted her, and vice-versa didn't sound all that appetizing either.

But she'd still licked herself alone, just to try it. Since starting her heat, her pussy seemed to taste sweeter than usual, and it felt much better than it normally did when she was just cleaning herself. She certainly found herself doing so more often. But while running her tongue over her sex felt good, it wasn't quite what she wanted. She felt like she was trying to scratch somewhere she couldn't reach. Sussie knew she needed the warmth of another, and she was determined to hold out for a stallion.

But sometimes, at night, when Sussie could hear the muffled moans and whinnies of other mares in heat, with their tongues lapping away at their sex, she could feel her own body itch and beg to be filled deep by anything- tongue or hand or even hoof. In those moments even she felt tempted to raise her hindquarters to the stable walls and join the other mares in their midnight orgy.

Then, finally, the day came. Sussie awoke to find the breeding blanket draped across her stable door, a sure sign that she would be meeting Bishop that day.

She paced her stable the entire morning in anticipation. Then she paced all afternoon. When the stable doors finally opened, she bolted out excitedly- only to find that the handlers were only letting the mares out to relieve themselves, as they did every day. She goose-stepped around the field in frustration, ignoring the giggles of her stable-mates until she was lead back into her stable. Could the ranchers really have forgotten to breed her? What would happen if they never did? Surely she'd go crazy, she thought... but they can't possibly have forgotten. She knew there had to be a reason. But why?

Sussie got her answer that evening. She heard ranchers carousing outside as they returned clumsily to the stables, drunken and happily shouting at one another. There must have been a race that day, and judging by the celebratory tone, the Carro Ranch had seen another win. Her handlers had probably been out all evening celebrating. Sussie balked at the idea of having to wait another night to lose her virginity. Her neck ached from pleasuring herself so often. She knew a drunken ranch hand wasn't the ideal choice to oversee her breeding safely, but the horny mare was ready to take that risk. Going a whole 12 hours without Bishop's cock seemed like agony. She needed it right now, time of day be damned.

Just as Sussie was beginning to lose hope, a sound made her perk her ears up in excitement-

"Ah, why not. It's a warm night, we're all up anyway."

Her handlers had returned! She'd recognize those gruff voices anywhere.

"Yea, we may be too far-gone to hit the brothels... But I wouldn't mind watching her get bred. It's about time, anyway."

Sussie blushed at the handler's crass remark, but her mind couldn't linger on the offense for long. As long as they helped her get under a strong, thoroughbred stallion, they could say whatever they wanted for all she cared. So what if she was a virgin? She was ready. That was all that mattered. She shivered excitedly as her handlers bridled her, happy to feel leather over her skin again. Most of the mares who would have cheered her on as she left were sleeping, but that was fine with Sussie- she didn't need any encouragement.

Finally she was lead out into the pasture. Sussie had been lead out countless times, but tonight everything felt like a new experience. She found herself savoring every little sensation around her. The rough sensation of leather bridle and rope sliding over her lightly-furred skin, the warm, soft feel of the ranchers hands at her back and sides... All these ordinary things had never felt so good. Every sensation lingered on her skin, and Sussie shivered in anticipation as she was tied in the breeding stocks. From here on she would be unable to leave until her stallion was good and finished with her, which was just fine with Sussie. To other horses and ranchers it may have seemed barbaric to tie a horse down before breeding them. But Sussie was young, and knew no different.

She shivered in excitement at the sound of Bishop's stable doors opening, biting her lip at the stallion's approaching hoofbeats. The sound of her mate approaching, her long wait finally over, made the young mare blissfully giddy with anticipation. Hitched up with her legs spread, she was more than ready for him.

"Sussie?!"

A familiar voice rang out across the pasture. Sussie raised her head in shock. That wasn't Bishop's voice... That wasn't Bishop at all! She turned her head to see her own brother, Toddy, being lead toward her. They had a palomino stallion, all right, but they'd picked the wrong one!

"Toddy!" Sussie gasped, quickly trying to close her legs as tightly as possible- there wasn't much else she could do to protect herself besides lower her tail. Toddy, for his part, began to buck, attempting to break away towards the stables, but the drunken ranch hands were having none of that.

"Ey, Bishop, what's the matter!

"Maybe he doesn't know she wants him."

"Well then, let's make it a little clearer for him, shall we?"

Sussie felt a hand lift up her tail, exposing her to her brother. She quickly whipped her tail back to where it had been, moving it as quickly as possible to keep it from the handler's groping hands. It was to no avail though, as the man's hands caught her tail in a tight grip, holding it up out of the way. Sussie gasped as she felt the rancher cupping her pussy with his palm, feeling his fingers brush up against her most sensitive place.

"Yeah, she's in heat alright, I can feel it. No reason she should be resisting this much..." The rancher continued to stroke Sussie's pussy, letting his fingers dip between her folds just lightly. "C'mon girl, show us a little love, would you?"

Sussie tried not to feel the rancher's hands, tried to put her mind elsewhere- but she could hardly deny the pleasure he was causing her. His fingers caused her to shiver and shake in her ropes, as every muscle in her body ached to push back against his hand, to let him sink deeper and deeper into her. She could feel pressure building inside of her as the rancher's warm fingers slid along her most sensitive edges, and she trembled unwillingly.

The pressure inside her built and built as her heat swelled in response to the rancher's warm fingers teasing her pussy lips, pressing inch by inch into a place the young mare had never felt explored. It was so hot, so new, so overwhelming and-- Sussie let out an involuntary squeal as warm fluid rushed out of her, bathing the handler's palms in her excitement as every part of her body tingled with pleasure and release. The man holding her tail let go, and she did not lower it.

"There we go," the handler said, withdrawing his hand. "Let our stallion smell a little of that, and he'll know."

Sussie's head was still a million miles away, her body swimming with desire. She needed to be filled, the pressure was building up inside of her again and aching to be released. God, if only it were Bishop behind her, and not... She tensed her legs and stood back up straight, the harsh reality of her situation now clearer than ever. What she'd done- no, what the rancher had made her do- was a clear display of heat in clear view of her brother. Now it was Toddy's job to resist until one of the handlers realized what a horrible mistake they were making. She lowered her tail and tried to make herself look as uninviting as possible. Toddy, for his part, snorted and whined in discomfort as he was pulled towards his sister. It wasn't too late. The ranchers may give up, or realize what a horrible mistake they had made. There was still time.

Sussie's gaze darted from the ranchers to her hitch points as she looked around desperately for some way to escape. There seemed to be nothing she could do. Then she felt her brother's hot breath on her privates. His face could only be a few inches away from her needy pussy, exactly where it didn't belong! Probably Toddy was trying his best to pull against the rancher's guidance, but he was tied up and trapped, just like her. She had to stop him somehow.

Sussie tried to press her legs together. She draped her tail over her unwilling sex. Whatever she could do to turn her brother away, she did. But Toddy seemed paralyzed by the heavy scent before him... He wasn't turning away. In fact, quite the opposite. She felt his warm breaths get heavier as his mouth drew closer to his sister's dripping sex.

"Toddy!" Sussie gasped, "Stop! What are you-"

She was interrupted by his long tongue suddenly entering her folds, as Toddy began to taste his sister. Waves of pleasure washed over her as his invading tongue delved deeper, tasting her depths and causing the young mare to shiver all over. So this is what the mares were doing to each other all this time! Her feelings of disgust and fear were washed away by the warm sensation of her brother's tongue.

It seemed Toddy couldn't help but lap at her pussy, slurping faster and faster, hungrier, his long muscular organ delving deep inside of her, further than her tongue could ever have reached. His lips were pressed right up against her pussy lips. She could feel every one of his wet, heavy breaths against her most sensitive areas, each one punctuating the slippery thrusts of her brother's tongue. Sussie bit her lips to prevent herself from crying out in pleasure, but she couldn't keep her pussy from feeling the way it did. Sussie was pretty sure her brother couldn't help himself and she was tied up, unable to protest. But god, why did it have to feel so good? Toddy may have not been able to resist her heat, but she had to try to snap him out of it before it was too late!

Suddenly, Toddy's tongue pulled out of her, and her brother stepped back. Sussie shivered, keenly feeling the empty space left behind. She needed filling as soon as possible. But by someone else, for god's sake! Sussie could hardly see what was going on behind her, but she had to hope for the best. Maybe the ranchers had realized their mistake. Maybe they were about to lead Toddy away, and in his place Bishop would...

"Alright boys, let's get him in her before he changes his mind again."

"Mmff... No!" Her brother's muffled voice rang out from behind his bridle. The painted stallion in protest as he tried to avoid being guided on top of his own sister, but it was to no avail. The ranchers would have their way. Sussie felt his hooves first, then her brother's full weight settle on her back. Now there was only a light blanket separating the two... but not where they needed separating.

"I'm- I'm going to try to jump off sis, just hold still-" Toddy gasped into her ear, his voice strained from resisting his own ropes and bridle.

"O-Okay." Sussie mumbled. It wasn't like she could go anywhere, being tied to the breeding stocks and all. She knew Toddy was doing her best to stop from doing the unthinkable, but her brain was still swimming with hormones. She felt useless as her brother reared up and off of her back, hooves flailing as he tried to reposition himself away from his sister.

"Jesus christ! What is wrong with these horses?" "The cunt obviously wants him." Commented a rancher. But Toddy landed back on the ground. Disaster averted, he snorted furiously at the indolent ranch hands.

"I think our girl here is a little cock shy, that's all. She sees that big thing swinging and thinks it's gonna hurt her." (Sussie blushed at this comment. She really didn't want to think about her brother's 'thing' swinging, or its size.) "Happens with virgin fillies all the time- there's only one thing for it."

"She wants it, but she's scared?" Replied another man. " God if I ain't heard that one before. Whatever you gotta do, do it."

Sussie felt her handler stepping behind her again and braced herself. Whatever he does now, she told herself, no matter how good it feels, I will not give in. The stakes are too high. She could handle another night in the stables, heck, she could handle another few months in the stables if it prevented her from getting pregnant by her own brother.

Of course, she thought, another month in the stables wouldn't even be that hard...especially now I know how good another horses' tongue feels...

Sussie felt a hand slip between her folds again, this time going inches deeper than before and interrupting the young mare's thoughts completely. The man was pushing his fist into her slowly, and it was all Sussie could do to keep from moaning and gripping him with her inner muscles. She was tight, as to be expected from a virgin, but wet, and so close to orgasm. Each inch of her was rubbed deliciously by the rancher's dexterous hands. Spasms of pleasure jolted through the horse's body with every motion. She couldn't help but grip tightly around his fist, riding his forearm like a stallion's cock. She had never imagined that a human could make her feel so good! And here she was, pumping around a human man's forearm like a lover's cock.

Suddenly the rancher pulled his arm out of her. Sussie's cum dripped out of her wanting folds. She whinnied indignantly, every thought of escape gone. Why had they stopped? She was so close. She felt something big and warm return to her entrance, and pushed back insistently, letting it slip between her folds, guiding the rancher's fist back where she needed it. Human or horse, she didn't care- she just wanted something inside her. Then she felt the weight of a stallion on her back. Whatever was inside her was bigger and longer than the rancher's arm, and still pushing.

Then, through the heat-soaked haze of her thoughts, Sussie realized what was happening.

"I'm sorry, Sussie..." Toddy groaned into her ear. "I can't help it."

Toddy deflowered his sister in one thrust, pushing himself deeper into her than any human man could ever hope to. Sussie could only moan in response, the pain of her incestuous deflowering quickly washed away by waves of confusion and pleasure.

It was done. As Toddy pulled back, Sussie half hoped that he would slip back out of her, that maybe the handlers would come to their senses before it was too late. Then she felt him pushing deep within her folds once more, this time coming to rest right up against her cervix. Now she knew that no one would be coming to save them.

Toddy continued with short, easy thrusts into his sister, perhaps to ease the pain of his entry, or in an effort to keep himself from cumming too soon. Sussie didn't know. She tried to keep her mind clear, tried to ignore the fact that her brother, her own brother, was fucking her.

But the stallions thrusts became longer, his breathing heavier, the longer the two continued to copulate. Toddy's precum bathed his sister's inner walls, mixing with her own cum and allowing him to slide in and out of her with barely any physical resistance. Sussie felt her brother pushing deeper now, encouraged by her own warmth and slickness. It was all she could do to keep from clenching down around him as he penetrated her. "Toddy, slow down!" She gasped, though in part of her wanted just the opposite. Toddy's only response was another heavy breath, accompanied by a long, exquisite thrust deep into his sister. Maybe he knew...

Whatever the case, Todd's thrusts were getting faster and more consistent. He would cum soon. He no longer waited between each thrust in hopes that the handlers would stop them in time- Now his cock lingered deep within her, spurting precum into her fertile womb with each thrust. Sussie could feel him twitch within her, she couldn't help savoring how his ring rubbed against her inner walls, warm powerful muscles moving together in harmony. She found herself pushing back against her brother in time to his thrusts. She no longer tried to make his cock slip out of her- she needed it's warmth, it's fullness, all of him. It was too late. She wanted her brother's cock and she needed to be fucked. She was so close now.

Toddy felt the change in his sister as her body stopped protesting him. He dug his hooves into the ground as if spurred on, throwing himself onto his sister's back, fucking her like a true broodmare. The beautiful horse beneath him wasn't his sister anymore, but his mare. A womb to bear his strong seed. His bitch. The handlers were yelling lewd phrases, cheering Toddy on as he fucked his sister, but neither of the horses paid much attention to them. Toddy was past the point of needing encouragement. Screw Bishop, he thought. Wasn't he stallion enough? Wasn't he a prizewinner? Toddy crouched lower, trying to push more of his cock into his sister, determined to give her his foal.

Sussie threw her head back and moaned as her brother positively pounded her, the pleasure all too much, her orgasm built to a loud climax as she came a second time, clenching her brother's cock within her and spilling sticky fluid all over the two equines. Toddy bit his sister's neck to keep himself atop the orgasming mare, and the pain of this coupled with the pleasure of orgasm sent Sussie into ecstasy. Her whole body rippled and quivered under her brother's weight. Her cunt gripped her brother's cock, practically milking it as it pumped in and out of her willing pussy, and she moaned loud and long enough for every horse in the ranch to hear. A few ranchers cheered lewdly. Toddy bucked faster into his orgasming sister, oblivious to any sound but her moans and the wet slapping of their sex. Her slippery fluids made it ever easier to push his thick cock even deeper.

After what felt like eternity, or maybe just a moment, Sussie's orgasm finally faded. With it, cruel reality seeped into the mare's mind. Her older brother's cock was still buried deep inside of her, but she had enough strength left to try to buck away. It wasn't too late! She looked around wildly for an escape route. If she kicked back, she could possibly knock herself free- She struggled recklessly against her restraints. Yes, it was possible! If she just got free now, she could-

Toddy surged forward, the first of many splurts of cum erupting from his cock, and splattered his sister's womb in stallion seed. He'd had long given up on pulling out in time to prevent cumming inside. He bred his sister in earnest, his orgasm building with each thrust, each time releasing more and more of his seed into his sister's womb.

Sussie's mind screamed out in protest, but her body did the exact opposite. Escape was completely forgotten as the pleasure of being bred took over. Her pussy tensed and squeezed warmly around his cock, enveloping him in slippery heat and holding him deep inside her. Toddy's hips were flush with his sister's by the time he stopped thrusting, letting the full length of his cock twitch and quiver against her cervix with the last of its emissions.

Sussie let out a whimper as her brother's softened length finally pulled out of her, releasing their cum onto the ground below them. Sticky fluids dripped down her legs and pooled between her hooves.

"Oh god..." Toddy gasped, the reality of the situation dawning on him. "I'm sorry...."

Sussie sighed, blinking back tears. How long it had been since she'd had a conversation with her brother, how many weeks it had been since they were able to spend time in each other's presence? She'd had to give all that up, just prevent what had just happened. She'd forgotten how much she'd missed him. What had just happened was horrible, but it didn't change the fact that they were brother and sister. She loved him, no matter what.

In a way, she was happy that the worst had come to pass. It was over.

"It's okay, Toddy." Sussie replied, "Really. It's okay."

"I... I love you, Sussie." Toddy said, looking nervously into his sister's eyes. But Sussie wasn't listening. The exertion of their mating and the stress of the night had finally caught up with her. She was exhausted, her brain in a place that could barely process her brother's loving words.

"I love you too..." She mumbled.

The rest of the night was a blur. Sussie barely remembered being untethered from the breeding post, or being led back into her stable, where she fell asleep almost immediately. Her stablemates, usually chatty after a breeding, were uncharacteristically silent. Sussie didn't know whether they'd witnessed her horrible rape or had slept through the night in blessed ignorance. She was too tired to care.

.......

The sun rose on a new day, and Sussie rose with it. She remembered the night before hazily. So many new feelings, pleasure and pain, betrayal and burning desire all coupled together in her mind... Her brother had fucked her, that she knew. It had been wrong, and horrible, and terrifying... And yet her pussy didn't seem to care about any of that. Her body still burned with desire, dripped with need. She felt as if she hadn't been bred at all, and needed to be bred again.

She sighed, defeated. So this was what it was like to be in heat. Maybe it was better this way. Maybe, with just enough pleasure, she could forget what had happened to her. She dipped her head to her pussy, and licked.
