This is one of my favourite horse fuck fantasy stories. It was originally written by someone called "Nyllat", but I substituted his main character's name with my own.
The is about fucking large horses in the (probably) most unrealistically way possible. It involves internal stretching, and loads of bestiality. This is intended for adults 21 and over only. If you are offended by graphic these descriptions of a sexual nature, please, don't read this or download it.
If this is illegal where ever you are reading this stop now.
I hope you enjoy the story, I know I did. If you do enjoy them (also if you do not), please let me know in the comments.
XoXo Missy Maaike
Chapter 1
Tall tales about stallions are a girly tradition in this part of Kentucky. For example, all Missy's friends said they went commando while riding their stallions bareback. These newly teenage girls giggled at that, and teased each other about their pussies just aching for more horsy thrills. They also egged each other on with wicked dares. Missy, however, just listened as the stories progressed: working up a lather on the withers, jacking them off during wash-down, and, of course, bragging about how big their units were. Most of these were lies, especially about giving head, but the shy girl believed, because she needed to believe these others had the same... needs.
Missy was the youngest and smallest in her clique. Daughter of a jockey, she was reared around stallions on a breeding ranch. Even so, no one guessed how deeply she burned with her taboo needs. This slender girl vibrated like a reed whenever a stud whinnied his lust. She went to all the toppings, which is what her father called the breeding of a mare. She always came when she saw this, even before puberty. Now, four years into her blossoming, she ejaculated so hard she had to start wearing both maxi-pads and Kotex, which she still soaked right through to her panties. Her dad and others were always there, so she never so much as panted, but, on the inside, she almost died for wanting to be the mare! Afterwards, she'd run back to her room and masturbate, sometimes for hours on end, until she had finally tired out her bestial lust.
This fair, dark-haired waif didn't tell anyone, but she also got herself off while riding bareback, and especially on Zeus, her favorite stallion. On him she would just ride and ride, and cum and cum, in a complete daze, and she would cream so big that she'd have to wash her drawers in the crick, and ride home after dusk, so she could wash him down before being seen.
Now, the Kantwell Breeding Ranch had a lot of studs, and their daughters loved all of them. Allison, Missy's older, much bigger, sister, liked the fast ones: Arabians and Quarter horses. Missy, however, liked 'em big. To her, Zeus was the best because he *was* the biggest. He was an American Saddle-Bred, with withers a full two hands above most in his breed. But, it was his penis that put him in a class alone. That unit was absolutely gigantic, even bigger than on most draft horses.
Indeed, his mighty rod was so big that most mares needed some special help, which the equine veterinarians were all too ready to give. Missy said she wanted to do that someday, so they were all too happy to show the pretty girl their salves and drugs, and to let her watch and learn.
Watch and learn she did. It was still rough for these doctored mares, but Zeus was almost compassionate, and once inside, his grand tool seemed to take every mare to sheer bliss. Indeed, he worked the smaller mares with so much care that he would actually take them much deeper, and much longer than the others. And, in Missy's eyes, those special mares, the ones that finally took ALL of Zeus's prodigious penis, and that he kept topping for so long that they finally collapsed, seemed all but die with pleasure.
Of course, Missy knew that, no matter how much she wanted it, taking in Zeus's almost magically durable sex beam into her small body was completely impossible. Still, it was her fifteenth birthday, and that mighty member was almost perfect for what the waifish girl intended as her private celebration. She was so embarrassed by her plan that she rode into the woods alone, then used her mom's best scissors to bob her long hair so it wouldn't catch on anything. She also cut off her jeans above the pockets, and cropped her tightest tank top just below her rampant bust. This was something she'd wanted so bad she was fit to bust, and she wanted to be just as slutty as humanly possible while she did it. So, the hot waif also ran a braided bullwhip through just the side loops on her pants, around her waist twice, and cinched herself down to 18".
Thus transformed, the libidinous teenager fantasized about Zeus as she rode him bareback. She envied those smaller, medicated mares. .oO(And I'm tiny compared to them ... what would he do to me...) More horny than scared, the young teenager humped her hot mound on her horse's withers with real abandon.
She had done some of this before, but this time was special. .oO(No chicken exit this time. Either I'm doin' it, or dyin' tryin'!) She thought as she finally reached the creek and dismounted. This was overly dramatic, for she really only planned to ride that big cock like a fence rail, not really fuck it. She'd starved for this, and, if Zeus's phallus could actually hold her weight, then that would be worth the hunger. Hitching her britches so far up her natural gap that her labia bulged out both leg-holes, she rubbed her wet mound all over Zeus's back leg. The denim crotch soon sopped with her pussy-juice, and bunched up like a big rope. That lusty stuff also trickled down her tender thighs, making both glisten with wet ribbons.
Clutching the reins to steady her shakes, the 85 LB girl leaned forward and gazed at the phallic object of her desire. She practically crackled with lust just imagining actually straddling such a mighty thing! Now, at her secret spot, Missy's mind was lost, and she was primed for more orgasms. Cumming had been fun while riding, but now she needed to focus. However, her delicate knees wobbled, and her narrow thighs and gaping pussy felt so wonderful that she could barely walk.
The 900 LB champion stud turned around and abruptly sniffed her girl-parts. He seemed to really like her! His hot rod surged way out and started to stiffen. The elfin brunette gave an open-lipped grin. She didn't know that Zeus was also her mom's favorite lover, or that the 40-something blonde woman had mated with him since he was a colt! All she knew was that this beautiful horse was as randy as she was, and that she was damn proud that her tight little body could give him such a big hard-on.
Seeing such huge stallion prick should scare anyone, but it only thrilled this girl. She squirmed a bit, and then, giving in to desire, she plunged a hand into her skimpy shorts, grabbed pussy, and wrapped her slim thighs around the closest foreleg. Her impromptu Daisy-Dukes got totally soaked as she humped away, and her girlish hips gyrated in a most womanly fashion. Missy had always worn a bra since she was twelve, but not now. Her nipples got obscenely hard, and her boobs seemed to swell luridly as she pressed them into Zeus's fur. At the same time, she fingered herself to a pretty good orgasm, but it wasn't the big release she was after.
Missy reached under her skimpy top and cupped her high, pointy rack with pride. She'd dressed like this for Zeus, and he was actually watching! Feeling absolutely naughty, and super-sexy, she lifted her top. Her breasts were now C-cups, and swollen so tight they didn't even crease underneath.
Zeus tossed his head and snorted approval.
Missy retook his reins and pulled herself back into his shoulder. Twining her fingers in his mane, she enjoyed the muscles and fur on his powerful, arched neck.
"I know what you want, boy," she whispered.
The stallion pricked up his ears. The hot, young trollop slid under him for a languorous dick rub. Already stiffened, her light touches quickly brought him up to a raging erection. Then she stopped. Zeus always seemed horny, and she didn't want him shooting too soon. She knew *he* could get off more than once, but she had plans for this particular load. The stallion quaked and nickered, making her feel all the sexier. She imagined his great mass actually attracting her loins like gravity. She tingled all over, especially at the insides of her trembling thighs. .oO(Oh yeah...) Now her pointy nipples ached and her clit sparkled, and she was so going to do this. She smiled at her own shamelessness.
"C'mon, boy," she said.
Toughened by hours of rough frigging, Missy's little moneymaker squeaked as she led Zeus to the most secluded spot in the trees. He halted automatically at the small, sun-dappled glade where he'd been serviced so many times before. The teenager's plump tit-mounds bounced merrily about as she eyed that gigantic cock and huge balls. If anything, his prick was now even longer and fatter, like her gaze alone was enough to bring him off. A full two feet of turgid cock-shaft now extended from his tightly stretched sheath, putting the blunt tip almost at his forelegs, and that was flared to over 4" across! The mere sight of all that horse-cock made the nasty little libertine's mouth water. Heck, it made her dizzy with desire.
Chapter 2
The stallion tossed his head. His flowing mane rippled, and one wild, black eye turned on the girl's elevated bottom.
"You want me to do something about that nice big hard-on, don'tcha, boy?" Her voice was a throaty whisper. "Something nice."
The horse's prick, almost on cue, heaved upward and slapped his lower chest. Pre-cum sluiced out with a sticky surge. The giant stud pawed at the grassy earth and made a moist nickering sound. He was more than ready.
Missy giggled. That jolting stream just hinted at what the stallion wanted to do to her, and she longed for it. She shucked off her cropped top. She didn't want to get cum on it. Then she unwound and thumbed down her shorts. Her delicately flared hips squirmed about, and she shuddered with dissolute delight as she sank to her knees and leaned in under her special horse.
Zeus stood still, his haunches twitching slightly in anticipation of the coming pleasure. Missy was quivering aplenty, too. She longed to milk this gigantic shaft, and to completely drain those huge balls. She reached under from the side, palm upward, and ran her hand along the veined length clear to the root. The foot of thick shaft felt like a wet cannon, his long sheath felt soft as loose suede, and his balls felt bloated like goose eggs! Having such fat fuck-rod throb in her hands overcame the last bit of Missy's shyness. She grabbed on and stroked it with both hands.
Zeus snorted impatiently. This girl was slow compared to her mom, and he was now so stiff that his shaft vibrated, setting the girl's hot body to tremble in sympathy.
Missy swung her squirming hips in behind the stallion's spread forelegs and backed between them. She had to keep backing up until those legs were at her armpits. Only then could she face his mighty member, which she greeted with hot, panting breath. The great prick flared wildly, and shot clear fluid right into her mouth. The piss-slit gaped open and closed as pre-cum ran down onto her hands in a hot trickle. Missy gulped and whimpered with desire, but this particular cock was way too big to ever pass her lips. Still, his salty pre-cum made her so hot she could cream as she licked it. Giddy with lust, the country girl leaned in and swirled her tongue slowly around the tip of the horse's cock-head. She gathered up the rewarding cum-drops, letting them roll around on her taste buds, savoring the stallion jizz, before tossing her head back and swallowing.
"Ummmm," she purred. That dollop had her ravenous, and Missy was in reverie when Zeus pressed her. Encircling the proffered cock with her cherry lips, the hot girl pressed back. Her face spread and her tongue drove into the slit. Unable to take it into her mouth, she rubbed her hands up and down to milk it. More jizz came, and she tongued it up and swallowed.
The horse bucked a little, making Missy worry, not that the half-ton brute would violate her mouth, but that he might suddenly crush her delicate body. Still, she squirmed in and gave the best head she knew, rubbing her pretty face all over his huge glans. She wormed her tongue deeper in his urethra, and she felt cum bubbling in there, trying to get out. Whimpering her excitement, the tiny teenager put her palms around the prick-shaft, just behind the throbbing head, and pulled. She could not touch fingers to thumbs with both hands! Jacking it full on, she pressed her lips hard to catch the flow.
Zeus was used to being tied back with Missy's mom. This strange freedom had him holding back with worry. Still, this much younger filly both pushed and pulled with abandon, sending him over the edge. His cock-head flared to full majesty, almost dislodging Missy's jaw. She gave a little gasp and pulled back. That monster was now to 4.5" across!
Spuurt! That nearly cauliflower-sized cock shot like a hose, splattering the pretty girl so good her face was drenched. Missy grinned and smooched away, lapping the tip of that prick. Her lover came forward and shot again. Setting her jaw as wide as possible, the greedy girl collared the dark-meated wedge, and then that stallion shot for real.
SPUUUURT! The pretty girl sucked and swallowed hard, but the stallion came harder, so she simply relaxed her throat. Even with horse-scum blasting clear into her belly, and her hollowed cheeks puffed out like a chipmunk's with that massive flow of horse-spunk, Missy could not take it all. Her tummy took a lot, and her lungs and sinuses also got some. She held on with wild desire, but the rest still boiled out past her lips.
S PURT! SPURT! SPURT! .oO(Ohmigawd! This is amazing!) Missy exulted as her tummy visibly swelled with hot, sexy, stallion-cum. Her throat was open and her green eyes were drooping with slutty pleasure. Jet after jet pulsed in and washed straight down, even while splashing out and started running down her throat to drip off her nipples. Her face a mask of pure desire, this horse-loving virgin wallowed in this excess, an amount large even for a draft horse, and far beyond what she could ever consume.
Missy knew that Zeus was a randy stud, and she was still amazed. Milking him in a frenzy of cum-guzzling lust, she exulted in opening herself to this mighty beast. She wouldn't have minded at all if he just magically rammed it right down her throat and out the bottom of her tummy! That was impossible, but she wanted him drained nearly dry before her next illicit act. She kept on jacking and sucking, and the stallion kept pouring out cum until that slimy cream finally overfilled the delicate child. Backing up, she gagged and gasped, and coughed to clear her lungs. Still, her hands pumped him hard. Jism dribbled out her nose, and thick gobs now slimed her nubile chest. Sitting back, she coated her taut belly and beautiful tits, and then proffered them to her lover. Meanwhile, her shoulders were splashed, and cum flooded down her back and trailed through the cleavage of her rounding ass cheeks.
The young slut only gasped and gurgled with the drunken joy. She had never seen or felt so much cum, and yet this stallion was still coming. A spurt hit her pretty green eyes as she spluttered. She couldn't see, but she still worked that awesome cock for more. She just couldn't get enough, and she wanted to bathe in its succulence. She actually wanted Zeus to go mad and take her right then, but, alas he was done. His last few drops came out in a trickle, and his mighty balls were empty, at least for now.
The girl gamely kept on, making sure that she had nursed out every last precious drop, and giving service to her favored stallion for every spasm of his quivering climax. She lapped up more mouthfuls, but her hypnotically surrendered throat could no longer gulp it into her full belly. Only then did she draw her lips away, shuddering and bouncing with the ecstasy of an unwilled climax. Her head kept hitting Zeus's chest. Missy pushed back between his forelegs. She willed her hips to stop, be they kept bucking and grinding until she felt her pussy exploding with its own gush of girly cum. .oO(Ohmigawd I want him! I want him so much!)
Chapter 3
After cumming, and then splashing around together in the warm creek, Missy's dream stallion still had a raging hard-on. He was ready, but was she? She hugged his meaty knob to her wet body, and used her nimble tongue to lave him clear down to his leathery sheath. As she did, her hips rose and fell on autopilot. She was cumming yet again, and this was still not the big release she needed.
Missy loved feeling so naughty for Zeus. She stepped out of the water, and that horse followed her naked, nubile beauty. Fifteen, and small, and willowy, she was finally ready. She felt attuned to this huge stallion, body and soul, and she longed to actually fuck him. It was impossible, of course, and yet, mincing beside the beast, a dreamy smile on her cum-flavored lips, her body buzzed with that very desire.
Now, there were the tales of women in these parts that did do horses, of women with pussies so damn big that men's cocks would just wave around like weenies in a water trough. Missy smirked. Then, her hips spasmed with her own lust. "Oh, hell..." Splaying her short, shapely legs she leaned over and sidled in. Creek water glistened on her body and dripped from her hard nipples. She gazed sidelong at over two feet of exposed cock, and her fantasy was broken. No way could such a mighty prick ever fit up her tiny hole! She'd be split open like a peapod!
Her, hot, naked cunt frothed with frustration as it passed above the desired object. Missy reached back past her erect bosom and hugged the giant prick. Her tummy quivered with lust as she rode herself back, running her hot crotch along it's girth and raking her hair-trigger clitoris along the bumpy top. "Ahhhh!" the debauched girl shivered, nearly cumming just on the contact. Smoosh! Her swollen labia slammed back into the vee between the stallion's belly and boner. The oversexed little girl grabbed on and closed her slim thighs around the massive sex organ.
"Ahhhh ... ohhh! Soo gooood..." the wild child wriggled as great ribbons of pussy-juice seeped down her to drip off her knees. Snuggling on the massive shaft, she almost purred with a sudden climax that shot ejaculate from her pussy.
"Oh, oh ohhh!" The sexy girl used her elbows to clamp her knees even harder as her gams channeled this big prick. She sawed it back and forth, right along her aching clit, then she gently lifted her feet. Her lover was now so stiff that he was actually holding her completely off the ground!
Feeling her heft, the stallion started to really stiffen and grow. Missy folded her legs around her partner's penis and tilted her hips into it, until the winsome girl was working her whole, folded body like an artificial cunt. Her lover's big glans reached the base of her neck, and that sex shaft bobbed at full horizontal, despite her weight. Missy gasped and moaned with delight, and rocked out all the harder. Her pussy-lips gaped completely open, and her needful cunt made rude, sucking noises as the rubbery sheath around that unachievably large horse cock sawed through it's vee and ground hard on her clit.
She relished this naughty contact. A stallion's cock was now flared in her cleavage. Her shapely thighs and calves were making a makeshift pussy, and she was jacking him with her hot legs.
"Yes! Oh yes, you nasty beast!" Giving her body and limbs to service Zeus only made Missy feel even more super-sexy, like she was at the edge of another kind of orgasm, one that was even more fantastic. .oO(Can a girl cum with her whole body?) She clutched that head, first with one hand, and then with both! She was now entirely touching every inch of that amazing penis, and she was working it. Her sleek legs and shapely calves caressed its middle, her lips, breasts and slender hands now stimulated his knob, her labia, buns and inner thighs worked its base, and her delicate feet tickled his balls. Everything slipped around just fine in her coating of cum and creek water, and plenty excess juices drooled to the ground.
The big stallion pawed the earth, then started rocking, humping into Missy's whole-body-cunt in foot-long fuck-strokes. The sexy brute had understood to not fuck her hard in the face, but this was new. She was riding his prick with abandon, and he wanted to really get into her hard and fast, just like a mare. He humped away, starting to move forward with the effort. The tiny girl gasped and moaned at her lover's verve, and she started cumming again and again. No, this wasn't the big one, but she did quiver all over with pure sex. Still servicing this mighty, meaty cock, she felt like she was mounted around the head of a great battering ram. Her eyes were closed, and Zeus was all she could think about!
The stallion's prick jolted and throbbed; transporting the overheated girl both physically and transcendently as he moved along. Her whole body now gave him a real sense of penetration, but no real sense of resistance. His prick-shaft pulsed with lust, his cock-head swelled, and she reveled to feel it! Back and forth, the girl gave a bareback ride beyond her wildest imaginings! .oO(Yes! Oh yes!) Her eyes saw stars, and she came so often she was breathless! She lost track of the rest of the world as that stallion's organs became her be-all and end-all.
"Cum, Zeus." she whimpered. "Please cum, cum up above my hot titties!"
The horse nickered. The girl gurgled. They were riding right at his sexual crest as he came up on the road. His whole powerful body was rising and trembling. His front hooves were dancing, and his massive organs were loading up with so much more cum he felt he might explode.
Missy now yearned to have all that powerful penis inside her body. Her ovaries ached to feel his load, and her womb knotted like a hawser. Still, she would settle for a spray up between her tits, but where was it? Not that Zeus wasn't having fun - in fact, waves of joy coursed up and down his body too, but he wanted to hide back in his barn, with this girl tied at her limit, like her mother. He didn't want to be up here with whatever traffic happened along.
Chapter 4
Doc saw the big stud horse going pretty fast, both humping and galloping. And he saw that slip of a girl riding his dick like a huge witch's broom. This was quite an amazing sight for Missy's newest neighbor. He had ignored the randy horse and naughty little girl earlier, when she was on his withers, but this was amazing.
"Cum!" the hot young girl was crying, pleading for them both. "Ahhhhh!" She cried in surprise as the stallion reared. Her lithe body was raised as the horse drew back, lifting her high with his throbbing erection. It was then that Missy saw that a huge trailer had pulled around them and stopped, blocking the stallion's progress.
Both horse and girl were too aroused to stop. He continued to rear and bounce, and she continued to jack his rampant organs with everything she had. The man dropped the trailer gate to make a gentle ramp into the open bed.
Snorting, nostrils flaring, and tossing his head about, Zeus thrust and danced. He was like some giant fucking machine gone berserk and out of control. Missy was as wild as the horse. Her eyes were rolling and she was drooling all over that huge tool as this new position let her arch down to again tongue her stallion's piss-slot.
Each time Zeus bounced, Missy's widespread pussy ground along his bumpy cock-sheath to mash hard into the vee where she now sat. There was a bang and rattle from the trailer, and, each time, she gave a little gasp, then moaned and panted as he carried her another step into the trailer.
Zeus's eyes were wild when the gate slammed shut. The whites were exposed, and his mouth foamed. He needed this second orgasm almost too much. The first one had been such a gusher that this one had taken almost a half-hour, but his alpha stallion organs were finally ready again. His already huge cock-head expanded all the more, and a second load rushed up his cum-tube, nowhere as big as the first, but all the more intense.
Missy was ecstatic as she felt her lover finally cumming! Her whole body tingled, from clutching hands to rubbing feet! Blam! It was like a gunshot as that jism splashed into Missy's mouth and all over her face.
That loud sound was also the noise of the stallion's metal-shod hooves slamming onto the wood floor of the livestock trailer. The huge stallion shot his young lover with cum several more times before slowing down and drooping. Flump! The cum-splashed child slipped along his slimy, softening shaft to land in naked disarray on the floor.
Missy crawled on hands and knees to again revel in Zeus's spew. She grinned, and her hips did an unwilled bump and grind. She was finally rushing to another amazing peak! She grabber her stallion's forelegs, pulled to her feet and writhed with sexy abandon. Not even thinking about it, she grabbed a big handful of her own pussy and pressed into her equine lover. All four of her small fingers went inside. She was cumming hard as she diddled her now oversized clitty, and splashes of horse spunk dribbled off her cum-soaked body. "Yes, oh God, yes!" She cried out in ecstasy as her thumb also invaded her widespread pussy. She was now simulating horse-cock with her own fist, and, it too was good. Sploosh! Her already dribbling sex suddenly erupted in another gusher of cunt cream, a load so rich that it splashed out around her invading, wildly plunging hand.
It was like Missy was hypnotized by her own lust, for she didn't feel anything but overwhelming, sexy joy as she took her own virginity in with a masturbating frenzy that was extreme even for her. Her much-frigged mons had just melted around her small hand like butter around a Missyng iron, and her cunt-cream had flooded out so much that the man watching could see it gushing from her gash.
The large-animal veterinarian hadn't actually intended a kidnapping. He was just moving back home from the Carolinas, and thought it best that this pair have some privacy. "Hooooo--wee!" He took of his hat and waved it like Slim Pickens as juice sluiced from Missy's pussy. "Girl, you're horse-crazy for shore!" Missy looked back at the middle-aged man. She had only cared about Zeus and having his horse cum spurt all over her taut body, but now she was afraid. Caught fucking her needful cunny with a whole hand, while clutching a stallion with the other, she froze; the pink flush of her fair skin blushed completely red.
The big man only shook his head and went to bolt the barn door.
Chapter 5
The horse doctor shook his head in disbelief. He has driven this amazing couple to his new veterinary barn. .oO(Not even mine.) he mused, for he had rented it from another vet that was now retired. Missy was chagrinned. A man she would only ever know as Doc, or the doctor, had picked them up and driven them to God only knows where.
She was also completely embarrassed. "Now, jus' look at you!" the man exclaimed. She was indeed a mess. Her hair and body were still smeared with horse jizz like finger-paint, and matted with dirt, straw and leaves to boot. She cowered in the back of the trailer as the old vet came in and took Zeus's reins. At 6'3" He towered over the small girl trying to hide her nakedness, but not over the massive saddle-bred horse. "Tell me who's your ma and pa and I'll take you straight back to 'em." His eyes lingered on her taut breasts bulging over her dirty arm. Zeus looked too. The fair-skinned girl flushed with embarrassment and guilt, but she shook her head and said nothing.
"Ok, tell me your name and I'll call the authorities. I saw you both, fucking right there on the road, sinning in front of God and everyone. Do you want to go to Juvey for endangering him?" Fearing that both she and her beloved stallion were in real trouble, the frightened girl again shook her head said nothing.
"But this is your horse, right?" Missy hesitated. The man derisively repeated the question. "Honey, is this your horse?"
The post-orgasmic girl shuddered at how the big man was staring at her, and especially at how Zeus was looking over his shoulder. "Y-yes."
"Good. He's a full-sized stallion, and *you* were jacking him, right?" There was a very long pause. Doc waited Missy out. They both knew what he'd seen. His silence discomforted the young hottie. Finally, she couldn't stand it.
"Yuh...yes..." she whispered, losing her breath mid-syllable.
"Good." Doc smiled and pulled Zeus up sideways. "Look. He still wants you." Missy couldn't help but look. Despite having driven him to climax twice in the past hour, that stallion's great big dong was again half-hard, and hanging out a half-mile. "Do you want him?"
Missy couldn't take her eyes off that awesome cock. Zeus wasn't yet flared, but his tip was still about 3" across, and, it was magic. Her lips trembled, as did her narrow hips. She was so... naughty.
The doctor was used to understanding patients that couldn't talk. He knew that this girl wanted this horse, even if she wouldn't say so. "OK, horsy-girl, take this and follow me." He handed over Zeus's reins and walked out to where they could see the hose and curry tools. "Now, you take your stallion over there and you both get cleaned up."
Missy stared at him. He leered at her naked, cum-covered breasts. She blushed. He smiled. "Look, don't tell me your name, and I won't tell you mine. Call me Doc. I'm gonna go find your clothes and come back. You need to get cleaned up." He turned and left.
It took two hours for Doc to unhitch his truck, drive out, track Zeus back to Missy's clothes, get some supplies and return. He opened a side door and entered quietly. The girl was there, with clean hair and body. Her horse was perfectly groomed, and she was nuzzling him, while fondling his chest and mane. Doc was impressed. That big feller's cock was easily two feet long, nearly half a foot wide at the base, and over a hand across at the flare! And yet, this little, 100 LB girl clearly bubbled with her lust for him.
"Here now, none of that!" Missy sat up, and Doc grabbed her off her mount.
"Lemme go!" Doc didn't.
"You can put on these dirty clothes..." he threw down the wet Daisy Dukes and the cutoff T-shirt "...ride out now, and pretend we never met..." he let her go. "...or, you can stay, and I can help make you and him..." he gestured towards Zeus's now pulsing erection "...a fairly happy couple."
Missy didn't leave. She trembled quietly as Doc led her to the veterinary room. "Time for a pelvic exam, horsy-girl. Get up here and spread your wings." This was awkward for both, him tying her legs to the restraint posts, injecting the muscle relaxants, applying anesthetic, and deciding to shave off her pussy tuft to pass time while these all took effect. "Oh, yes. Ain't that a pretty one."
Chapter 6
Doc pulled the little girl with the big, naked pussy toward him, spreading her knees. "And, deary me, I can see how your whole hand could fit inside." He kept talking as he dilated her with a speculum designed for sheep. He probed deeper and deeper, and finally pushed into her womb. "My, but you *are* a special one." Doc got a bigger speculum, one designed for mares. Missy held the table edge and whimpered as it went in. "This part is important, so try to relax." Doc squeezed the dilator repeatedly, watching Missy's flesh and counting the ratchet clicks. He'd applied anesthetics, but the pain still made the lusty girl close her eyes and weep. "There. Now for the real stretcher." Doc slipped Missy's expanded groin full with the biggest rawhide bone made. The girl gasped as the big end was forced all the way to the back of her womb.
"Oh, fuck, Doc. What're you doing to me?" she worried.
"It's an old trick to loosen-up tight mares, sweetie. You do what I say, and this will work you up to being horse big in no time." They both looked over at Zeus. "No, not him. Maybe some gals can go that big, just maybe, but not you." He looked down at her small hips. "Now, listen up. You won't be able to take this out without my help, but I'm sending you home anyway. It's safe enough for a day or so, but you have to come back. It will kill you inside a week."
Missy bit her lip and brooded on this. This fake phallus felt pretty humiliating, and she felt really stuffed. Still, she felt proud. .oO(He said I'd be horse big in no time.) She stopped grinning when Doc made her get up and straddle a sawhorse. .oO(Oh, Fuh-fuh...fuck!) She bobbed down on the cunt-stretcher, gasped and felt ill. It was like ... up un her lungs ... or something. Doc braced her upright and rubbed her tender tummy. "Yeah. That's it. Real easy now..." Now she felt like an animal, and rather humiliated! Still, it only felt all achy and weird, and it didn't hurt *too* much. With his coaching, probing and rubbing, the little teenager went deeper and deeper. She was proud when her pussy lips started kissing the outer knot. Her backside had also started riding on the sawhorse, and Doc was satisfied. "That's y'all's limit, fer now."
Missy held her tummy and panted. She could actually feel that big knot at the back of her womb, stretching her from there clear out to her labia! Then, when she stood up, she felt it sliding out, not stopping until again hung down 6" from her mons. She fingered and felt the 2" wide leather rod. Reaching lower, she felt the big knot, and her face blanched.
"Ohhhn! But, it's so..." Missy looked over at Zeus and blushed. "...thin." Now that she was actually going to fuck a horse, she was struck by the impossible size difference.
"Shush!" Doc held a finger to his lips. "You still have... a lot of training... to go. And..." he also glanced at Zeus, who was now munching on some fortified oats "...you may never have that one. We have to train the horse, too... Now, squat here." Doc helped her into a harness he'd rigged from bailing wire, D-rings and leather straps looped to Missy's belt.
He tightened her belt clear to the last hole. The girl with the lightly freckled cheeks gasped and blushed all the more as Doc hooked it to her pussy stretcher. "This won't be easy..." The exposed knot also caught the D-rings from the front strap, and he tugged up hard to cinch the front and back straps.
"Ohhww!" Missy gasped and palmed her tummy. "Oh, Doc, it sooh deeep..." she panted.
"Nah, it ain't near yor limit..." He lifted Missy to her bare feet. "...but it'll grow on you."
Missy frowned and looked at her now impaled crotch and midriff. Doc merely helped with her Daisy Dukes. The cunt-stretcher stuck out so far that these naughty shorts couldn't cover them and her belt as well. "There's a good girl." He used twine to tie two belt loops up. "Now, you don't worry about that big horse, but you do go home and hump' on that ol' bone. Try to get yorself down around the whole thing, but don't go too hard. You're nice and pliable, and pretty damn tough on the outside, but you gotta toughen up a whole lot on the insides, or ya'll just might bust."
"You be sure to come back sometime tomorrow, or else you'll be sorry. Meanwhile, take these pills to relax -- 2 now, 2 at bed time, and 2 in the mornin'." He gave some capsules with one clear end and the other pink. Then he helped her up onto Zeus. "Be careful riding home, and bring back another one that might actually fit." Doc didn't tell Missy to not talk about any of this as she rode away on her beautiful stallion. He figured that went without saying, but he was wrong.
The creek where Missy started this misadventure was only a 2 minute gallop from her family farm, and Doc's barn was only 5 minutes past that, but she took 2 hours getting home. She fantasized that bouncing her cunt-plug on Zeus would be sexy. It was. But she also felt numb, and a little queasy. Then she felt less numb, and rather ill. Even sitting at full rest was sickening, and she made this worse by worrying that she'd be found out. Pretty soon, she carried half her weight on her bent knees, and was still so sick that she had to puke 3 times. She only had to clean up twice, because the third time was only the dry heaves. Even then, she was so ashamed that she rode into the woods and hid till the last rays of dusk.
Chapter 7
Missy was soon so sore she called herself an idiot, and a dirty little horse-whore, and she hated Doc. She hated all men, and fantasized about turning him in. After all, she was a minor. But it wasn't the law she worried about. It wasn't even her friends. Hell, they'd probably be jealous, just like everyone was jealous of Allison, her older sister. No, she was worried about her mom.
Mom was amazing, six feet tall and built like an amazon, she towered over everyone, especially Missy, who took after her father, the retired jockey. The slender girl got down and just stood there, hiding in the woods, holding her horse's foreleg and trembling with discomfort and fear. Mom ran their stud farm with larger-than-life energy. Her word was law, and she was a good, Christian woman who didn't spare the rod, except when it came to horses. That was one thing mom, dad and Missy had in common. They all loved horses. Mom would be mad that Missy was out past supper, but that would be nothing if she put this stallion up without proper care and feeding. She smiled as she rubbed her arms and bosom on Zeus and felt his sweaty fur. That wouldn't be a problem - he'd been treated pretty well today.
Zeus nickered and nuzzled his youngest girl-filly. Her dark hair smelled good, and he still wanted more of her hot action, but he wanted to go home now, for his nighttime duties. The big horse nickered and pulled at the reins and turned towards the barn. "Yeah, boy, it's gettin' dark. Time to go, I guess."
Missy's legs were strong, and she'd normally just grab his mane and jump up, but she led him over to a deadfall and used the root-ball to get on gingerly. "Ffffuh...ohhh..." She hissed and gasped. She clamped her legs as tight as possible around her broad mount, but there was just no way to ride without some weight on her dildo going right to the back of her uterus. She leaned forward to put weight on her pubic bone. She cursed her cutoffs for being so skimpy, as just leaning forward more would show off what she was so ashamed of.
By the time she had groomed Zeus, Missy didn't get up to the house until bedtime, which worked out well for everyone. Mom got to go out and have dad help her get the ride of her life, for her favorite stallion took forever get off. She didn't know these were his third and fourth ejaculations that day, and she easily matched those two for one. Dad got to watch his gorgeous, busty wife get so wracked by pleasure and wrecked by size that he had to take her back to the house in a wheelbarrow, where he proceeded to ride her hot ass like a whole pack of wolves once she was cleaned up and put in bed. And, Missy got sent to her room without supper, where she put on her softest pajamas, crawled into bed, and cried herself to sleep. She was now more frightened and ashamed than ever, and she wanted nothing more than for all this to go away, like it had never happened.
The only person who didn't get what she wanted was Allison. Like mom, she was tall, blonde and leggy. She was also 17, slated to become a senior cheerleader this fall, and widely regarded as the best catch in school. That was frustrating, for she was now having a hard time getting caught, at least by the right boys. The manliest graduating seniors were now all in the military or off on some kind of summer activity. She liked those older boys, and had slept around with most of 'em, until she settled on Hank Jansom. Hank had a rig like small horse and the stamina of a large bull. He'd plowed Allison over the moon, taking her so deep, and so good that she always wanted more. She'd had done lesser guys since Hank joined the Marines, but she was pretty frustrated.
Tonight's date was worse, he wouldn't even cop a midnight feel. She'd had him park in the woods, and that dope only wanted to walk her to the fence so she'd be safe. Damn! She didn't want to be safe. She wanted a man! Sulking as she passed the barn, she heard mom moaning, and Zeus snorting. She crept up and the besting rack was creaking away! Hot damn! This had to be the biggest, wildest, fucking ever!
Allison was stunned. Mom had her legs around Zeus's flanks, and her hands pressing her boobs into his fur, and that tied-back bronco was plowing her hot body in foot-long strokes! And, dad was letting out slack! The horny teenager bit her big lower lip, then sucked her own blood to keep silent, and still she couldn't even blink as that stallion kept going deeper... deeper...
.oO(Where is mom putting it all?? That fucker's cock is more than six hands long! And, she was just crazy for loving it! Hell, she must be some kinda mutant superwoman!)
All of a sudden Hank's nine-incher was nothing. The over-sexed teenager's hands went straight down her jeans and up her blouse, and she was diddling herself with a vengeance. Meanwhile, mom finally reached her limit. She was still arching and moaning like mad, but Allison could also see the big jolt of that horse-cock slamming the far end of her mom's womanhood. Even with that, the horse-woman threw her head about with bestial abandon as that full-grown and fully engaged stallion fucked her so big Allison saw the bulge of his glans running right up into her chest!
Zeus strained against the yoke and doubled straps that kept him from simply bolting forward and splitting mom's ribs open. Dad had rigged this right up to his wife's limits. He loved her dearly, and they both loved horses, so he let her have all the horse-sex she wanted. He recalled that her pussy was almost a foot deep when she had Allison, and she added 8" of womb that very day! This was truly insane, for she was fully accommodating a stallion 18" long and 3" across. It was a miracle that she had Missy at all!
But even that wasn't what Allison saw. The Kantwells had crossbred this amazing percheron/saddle-bred colt. They named him Zeus because he was born both hung and horny. He was doing multiple mares as a yearling, and almost dragging the ground with his thick, 18" cock.
Mom started doing him EVERY day, while dad was giving him steroids, and he just kept getting bigger! Horse and woman gave each other the fucking of a lifetime, and they did it over and over, soon doing it several times a night. Ms. Kantwell was cumming so hard she was addicted. Her changes were gradual, but, five years later, the effect was enormous. What Allison saw was this great, muscular beast taking this amazing Amazon so big her tummy bulged, and so deep she was furrowed right up into her ribcage! And, she was taking that two feet of cock with its four and a half inch diameter glans, and just cumming, and cumming like a madwoman. Allison saw mom cumming so hard she thought it might kill her!
It was then that Allison stopped masturbating. She suddenly remembered something similar from infancy, and she cried. She cried all the way back to the house, for she was already walking and talking when mom abruptly banished her to a crib or playpen. Her little sister got to stay out there with mom and dad. Missy got all the attention, while she, Allison, was left alone for all hours at night!
Allison was angry, and jealous! No wonder she liked 'em big and rough! She was also curious. Missy didn't seem boy crazy like she was. Was that scrawny little hussy also doing stallions?
Chapter 8
The Kantwell's knew that bestiality was a cardinal sin, but mom seemed born to it. She just couldn't stop, but they both swore to protect their daughters, and worked hard to keep up normal appearances. Mrs. Kantwell kept a massive dildo in her permanently stretched-out cunt, and wore Spanx to justify her unusual flat tummy and control the occasional bulge. She also took her girls to church and worked hard to make their horse-ranch a success. And yet, with Zeus the super-stud seemingly always ready, willing and able, well, she just had to get herself plowed to orgasmic bliss almost every night.
Allison and Missy both sulked for two days. Both got grounded for staying out late, which meant that mom and dad stayed in the house to keep watch. Allison tried to get her sis alone, to say what mom was doing, but her parents seemed everywhere. Missy, meanwhile, stayed in her own room and didn't even come down for meals.
Actually, the slip of a girl was now embarrassed than anything else. The pills seemed to make her thirsty and kept her feeling full, or was that the huge cunt-stretcher? Anyway, she felt better the first afternoon, until she just had to pee. What should she do, stain the leather? ...risk letting the straps go? She decided to just hold it. That lasted one, long, sleepless night! The next morning her tummy was bulging, her breasts felt bloated, her belly ached, and she also really needed to take a dump! On top of that, she had just taken last of the pills that seemed to really ease the discomfort. Defeated, Missy went to the bathroom and took off the straps... IT WAS GONE! She felt around. Her cunt was all puffy, and completely closed. She fingered herself deeper and felt only the barest nib. She got a finger in the ring, but could not budge that big dildo. .oO(Oh, fuck! If I don't get help I really will explode!)
Missy was afraid. .oO(What have I done? Did the rest of it just melt?) She walked into Allison's room with only her pajama top and a look of worry. "Ali?" Her sister looked up. "You... you just gotta help me..." she begged. "Please..."
Allison grinned and closed the door. Missy knew that Cheshire smile. .oO(She thinks she's gonna play me. Well, I may be screwed, but I can still spin a better yarn than she can.). She forced a smile and whispered "I'm gonna fuck a horse."
"You mean like mom does, like, all the time, with Zeus?" Allison played, looking for a gambit.
Missy was stunned, but she recovered fast. "Yeah, HE's the one I'm gonna do."
Allison laughed. "You? With your scrawny ass? Do you even know how big he is?"
"Doc says I can." She pulled open her pajama top, and Allison was stunned by her swollen boobs. Then she spread her pussy lips, exposing the ring and base of her pussy stretcher. "With this."
"Holy fuck." Allison stared at something the size of a beer can stuffed up into her now top-heavy little sister. .oO(What the hell?) She forced Missy back onto the unmade bed. As she did, she felt the bulge within her sister's belly. "What is this? Are you, crazy?" Curious, the bigger girl pinched the ring and tugged. It was stuck. She stuck in a finger and pulled harder.
"Oh. Ohh!" Missy spasmed. She felt her cunt-plug moving everywhere at once, even way up in her chest. "Ahhh!" The young girl pushed her big sister off and sat up. Allison hit the floor with a whump, and she got mad. She jumped, ready to wallop her little sis, but the sight of something more than 2" across coming out of that little girl's big pussy stopped her cold. Missy held her hands over her abdomen and grinned at her sister's expression. "See, I'm almost ready!" she lied. She rocked back and forth to prove her prowess. "It's fuckin' awesome!" Actually, her churning guts made her queasy. Still, she was determined to see this through. She wouldn't show weakness now.
Allison watched in awe. Her tiny little sister was now impaled on the biggest phallus she'd seen, short of actual horse-cocks. She sprang up, got a knuckle in the loop, and tugged. A good 4" came out, and then it caught and stopped "Noo-ohh!" Missy moaned. Allison pushed it back. It was a tight go, but she was strong. "Ahhh-ah!" the scrawny girl gurgled with a mix of discomfort and strange pleasure.
Seeing the bulge moving on Missy's belly made Allison both furious and curious. .oO(How long *is* this thing? Is it that easy to get like mom? Why is it stuck?) She started tugging and plunging. It only moved a few inches at first, but Missy swooned and her pussy got looser. Allison kept pulling and pushing until her fist was moving in six inch strokes. Missy'd never felt more ill, or more sexy. She couldn't help but think of her intoxicatingly beautiful stallion. Pretty soon she was up on hands and knees, and each plunge was taking her closer to horse-girl heaven. "Oh sis!" she gasped, "It feels just like a big horse-cock's gone way up inna me!"
Then "Oh! OHHHHHHHHHHH!" Missy came so hard she damn near fainted. Arching, and spasming with an incredible release. her tight twat shot cum onto her sister's arm. "OH! OH! OHHHHHH!" She bucked her supple body, and her hyperactive Bartolin's glands got her pussy so lubed up that it ran with thick honey. "Oh, oh! Don't stop!" she mewled.
Allison did stop. "It might as well be my fist; by the way your sloppy cunt is shooting juices!" She appraised her now sopping hand. "I guess you *are* a horse-slut, just like mom!" She faked disdain to mask her own incredible arousal. "And, I bet I can just go as fast and hard as I want." The big girl braced her little sister between her off hand and a raised knee, and pushed and pulled with real vigor. This also flared her cunt open, and its natural bulge started working in and out as her hips did a needful bump and grind.
Missy, however, was suddenly distracted. .oO(Mom? Mom is fucking our stallions?) It wasn't news now, but it was still sinking in. The swollen, mushy knot in her womb now churned her stomach, while the wildness of her sister's fist pounding completely in and out of her pussy brought back images of her mom getting plowed by Zeus while she was still in a play pen. It was true! And that was what drove her over the edge.
"Oh! Oh Gawd. Please stop!" The over-stimulated little girl gasped. *This* panting wasn't pain, just an overwhelming desire to fuck Zeus. Her juiced-up pussy was now spreading and shrinking around a whole fist, and it wasn't enough. She now drooled from both ends, and only that biggest of all stallion's would possibly do. This epiphany drove her queasiness... "Oh. Urk. Blehhh-h-h-h..." she wretched hard, throwing up all over her sister's bed until her body ached with emptiness, and she nearly passed out.
Allison mistook that as disgust, and that was it for her. Her crotch was now soaked with her own juices, her hips were racked with sexual spasms, and she hated her sick little sister. "Oh, shit. Look at you. Mama's gonna throw a fit!" She easily tossed little Missy off the bed, and had the bedding balled up before it soaked into the mattress. She checked, and then ran the whole mess to the washing machine.
Chapter 9
Meanwhile, delirious with desire, Missy cinched herself back into that belt rig, pulled on a Lycra miniskirt and tube top, and heedlessly staggered out to find Zeus. That grand stud had really missed doing a number on Mrs. Kantwell last night. He smelled this overheated young filly and was instantly ready to do her. He took to the bridle no problem, but balked at the saddle. That usually meant riding instead of fucking. He wanted to fuck.
When Allison came back to the empty room and saw out the window that her sister was running to the barn, she hesitated. She was felt safer after making the bed, but she heard Zeus snort and stamp, and then she feared for Missy's life. Was that kid crazy? Did she want HIM? She ran out.
In the barn she saw that Zeus was gone. But, why was her kooky sister riding off without her saddle? Their parents were away, and she could get horse-fucked right here! The older girl saddled up Sultan. She didn't know that this big thoroughbred also did her mom. She chose him because he loved to run, and was rarin' to go.
Doc was really worried when Missy didn't return. Leather stretchers go toxic if untreated. He'd given her some antibiotics to take, but that wouldn't work for long. He shrugged his shoulders and kept working on mating harnesses to fit various size horses. He'd told that little girl to bring a partner that'd be a better fit, and he wanted to be prepared. He'd also made more than one harness for her, because he knew she was petite, but had only taken her height, not her real weight or full measurements.
Envisioning her tiny frame got the large animal vet thinking. She'll have to come back. That plug was so fucking huge it was a miracle that it fit at all, and, it would keep swelling. By now it had to be as big as any mare could take. He knew that thing could almost double in size overnight -- that was the point. .oO(Heh, she must be mighty damn uncomfortable about now.) Yes, he'd given her hormones like a triple pregnancy, but she only got a day's worth analgesics and relaxants.
Missy actually weighed 10 LBs. less than Doc's lowest estimate. Riding bareback on Zeus had the crazy little horse-lover feeling glorious. Allison had rekindled her spark by trying to pull the plug out, but it was well and truly stuck. She tried pulling it out to do Zeus right there in her own barn, but she heard Allison coming out of the shout.
Two days ago Missy's just-pierced pussy was raw, but not now. Up high on Zeus's withers, she was hot and wet, and nearly fainting with delight at how her leather log was pounded in and out of her body by her equine pile-driver. The end knotted in her womb was another matter. It was now just plain stuck, both in reaction to the hormones that Doc had given her, and by so much wild swelling. Speaking of swelling, her tube-top was now overly tight. It was fine two days ago, but the bounding and bouncing ride had her keenly aware that her breasts were now big and hard like grapefruit. She didn't know this, but Doc's hormone shots had induced a false pregnancy, including the big, sexy boobs and hot, scarlet nipples. She only knew that being so top-heavy was making it hard to stay upright. Her stallion's gait soon dragged her top down, and her boobs sprang free, with that band under her bust forced up by the bulge at the top of her formerly flat tummy.
Also on the list of Missy's now extreme complications were feelings that she was about to burst from a need to pee, and to take a huge dump. However, she really couldn't do either. Her pussy plug was so big and tight that her urethra was blocked, and even though she was leaning forward, the belt harness kept driving it back in so deep her empty stomach was churned.
Not that she cared. Doc would fix everything. She would either have the sex he had promised her, or die trying. Somehow, that thought left her pounding along in a transport of wanton bliss. She didn't even notice who was watching her exposed breast globes and red nipples, or the sexual froth that was now wetting her legs all the way to her stirrups.
Allison saw a few spots of foam and worried that Zeus was lathering. She raced her faster horse to catch up. That foam was Missy's! Her naughty sister was now so top-heavy she was all wobbly, and that pretend prude was so drunk with lust, and cumming so damn hard, that she might just fall off and kill herself!
"Gawd, you little slut, you're worse than mom!" Indeed. That tiny slip of girl now only took crazed pleasure at how her cunt was being pummeled ever larger as she rode. However, she weighed so little that Zeus's only overheating was from his unquenched lust. His nostrils were flared, his mighty cock was out and hard, and he had a catch in his trot like he was about to become a bucking bronco.
This surreal situation made Allison's blood boil. What could make her little sis so insanely hot and bothered? She felt both jealousy and rage as she pulled close and slipped a leg over to Zeus. .oO(How could both her mother, and her sister, be so horse-crazy? What was she missing?) She wanted to both stop this, and to make Missy go all the way. Then, when her pussy nestled into Zeus's bare back, she felt her own echoes of bestial lust.
Doc was surprised to see Zeus with 2 girls, and another horse following. He barely had the presence of mind to open the barn and close it again as they passed inside. Missy twitched deliriously as Allison handed her down. Holding her tiny sister m
