Penny In for a Pounding

17-year-old Penny had a short, trim body; round face; and embarrassingly large breasts. Even worse, her slim limbs and big, soft eyes made her look years younger, like a pre-teen that just suddenly got a wide crotch and huge boobs. Well, not really huge, because they were only Double-D cups, but they sure looked that way on her elfin body. More importantly, this oddly proportioned virgin had a secret hankering for horses. It had always been there, but her lust skyrocketed with puberty, and, at least for her, no mere boy would do.

Scouring the Web day after day, the foxy seventeen-year-old eventually found the Bareback Ranch out in Ojai – “Family friendly, with bareback horse riding and large private stables.” It was only a couple hours out of Encino, and looked innocent enough, except, there was this old picture that left Penny breathless. A girl about her age, in cowboy jeans, hat and boots, was astride a painted pony, with a Friesian horse rearing in the background. You couldn’t see under either beast, so both might be mares, but the rider’s bedroom eyes and open mouth were enough. Penny’s pussy got wet, and she *just knew*.

Even that could have been wishful thinking, as AirBnB didn’t reveal any names or locations, other than Ojai, CA. However, Penny read the clues. There was “#BRJa”… on the girl’s hatband, and “…Doe” monogrammed on her white blouse. Well, #BRJaneDoe was on social media, and claimed to be in Ojai; except that she was now older, and said she was the host. They kept in touch and strategized as Penny convinced her divorced dad to go there for some fun on one of her weekends.

Once Dad finally talked to the owner, Mindy Barnes, things moved fast. They drove up, settled in, and went for a swim. Dad and Mindy hit it off. Penny also met Carol. She was already out of high school, and said she loved horses. They talked. Carol competed in barrel racing, high jumping and dressage, which she said was like a beauty contest for horses. Her dark hair, wide hips and small breasts gave her a very different look than the busty blonde’s short frame and long ponytails, but that didn’t stop them from becoming bosom buddies.

At dinner, Carol quietly warned Penny to not eat much. “Save room for a real treat, once we are alone.” Penny hid a grin and only picked at her food. Meanwhile, milfy Mindy had dad’s eye, and she invited him out to dance at a local honky-tonk. An hour later, after a beautiful sunset, the two adults were ready to go. “Be safe, and don’t do anything I wouldn’t do.” The 40-ish woman told the girls.

Carol smiled. “Don’t worry, mom. We’ll be fine, and I’ll call if the horses start acting up.”

“Oh, I bet you can just handle any horse here.” Dad said, sounding lecherous enough that Penny blushed. “And, Penny, we may be out late, so, like, you can call me if you need anything.”

The round-faced girl gave him a perfunctory hug to hide her red cheeks. “Dad, you’re such a dork. We’ll be fine.” she whispered.

****

Dust from Mindy’s pick-up was still settling on dad’s Mercedes when Carol led Penny out to the big, modern barn. They were not talking, but they held hands and were panting. The younger girl felt like this was a dream, while the older one was pensive. Right there, in a white-painted stall, with thick straw and a full manger, was the same painted pony from the picture. He looked old and gentle, but also proud. Carol took a huge carrot from a bunch in a cooler, and he came over as they approached. “His name is Alphonse, and he was Mindy’s first horse.” Her voice roughened. “Mine, too.” She swallowed. “Would you like to give him a treat?”
“Y-Yes?” Penny also swallowed. “Is he dangerous?”

“Oh, yeah…” Carol sighed. “Very much so, (pant) especially to young, wayward girls…” and the way her voice trailed off made Penny’s nipples ripple against her bra cups. “Okay, so, hold this by the stem, and let him only bite off the first half.” She smiled. “And, don’t worry, he’s really gentle, and not really all that big.”

Penny’s hairless quim quivered with forbidden lust. “I…I’m a virgin.” she blurted out, and instantly felt like a complete fool. .oO(Oh fuck! What if this is all just a huge mistake?) She shuddered.

Carol grinned. The conversation had long since gone beyond misunderstanding. “I was a virgin, too. It really hurts at first…” She pulled Penny face to face, held both her hands, and whispered. “It all depends on you. I think you’ll like it, but you can still chicken out. If you faint, or shout uncle, then I can probably stop him. This barn is soundproof, because some girls like to scream…” She saw Penny’s jaw drop. “…Yes, there are *lots* of us.” She nodded. “Everyone’s different, but I think you will…” her voice got really husky “…come to really like it.”

Penny’s precociously top-heavy body flushed a vivid pink. Her voice went even huskier. “I…” she stammered “I’ll give it to him now…” She took the carrot and held it out. Old Alphonse reached his head over the rail, bit the proffered carrot, and munched away.
Carol took back the stump and had Penny doff her panties. “Undo your bra, too. You’ll like the freedom. Remember, crawl forward if he’s in too deep, but keep your hands away from his hooves. He’ll know what to do, and so will you, if you pay attention.” She led the still surprised teenager back an area with a soft, gray carpet, benches, and padded walls. Various chaps and bridles hung from pegs, and several sturdy wooden chests doubled as seats. “Diddle yourself, or let me know if you want any lube.” She left to bring Alphonse.

When Carol came back, Penny was already on hands and knees, in red leggings with gold trim. Her uncommonly large breasts dangled free in her knitted gray dress. .oO(I would have faced out…) the older girl thought .oO(…instead of towards the back wall. Oh well, maybe she wants it rough.) “Watch your hands.” she said, leading the pony’s forelegs to step around Penny’s quite girlish hips. Then she reached under and grabbed his already dangling penis. “Remember, uncle is your safety word.” She gave that well-used shaft a few strokes. It quickly rose and grew to be over a foot long. Still, it really wasn’t much bigger around than a good-sized man-cock as she aimed it towards Penny’s glistening vulva. .oO(Oh, Wow! She’s got a really nice little hole!) Indeed, for it already gaped a bit as the horse moved forward. Carol smiled. .oO(And, she don’t even have hair, yet.)

Bump! Penny’s gasped at her first ever touch of horse-cock. Then that beast’s legs squeezed her waist, and his flared cockhead probed against the fleshy pouf of her hot mons. “Ahhh!” The young girl’s head rose, her mouth opened, and she trembled and then froze. Her mind went blank, her hands grabbed the carpet, and her body thrust back.

Alphonse nickered. Yes, this was a hot one. His cock stiffened and grew, making Penny’s puffy labia squish open and surrounded the end of his glans. The girl moaned with pain as his tip was forced in. Another thrust, and she knew right then that her virgin body was way too tight for this. She shook with fear. However, her stallion lover started rocking away – doing a horizontal dance as old as time.

“Oh!, oh, oh…” Penny panted as that old horse repeatedly probed the pinch of her pussy. His glans had hardened up to 2″ across at the flange, and they both felt his tapering tip knocking hard into her hymen. This hurt some, but nothing, nothing in her whole life had ever felt so fucking hot! “Ah, ah, ah!” the straining strumpet gasped, and she pressed back on each thrust with a hard, determined desire.

Carol saw that and just grinned, continuing to watch as the once reticent little blonde started getting fucked pretty damned good.

.oO(Oh! Ohmigawd!) Penny felt pleasure starting up that was just too good to ever stop! The still-tight teenager felt her flesh tearing open and her labia starting to fold inward. Yes, it hurt, but she also felt a real stallion in her pussy, and it was intoxicating. Such size and vigor! Such length and strength! Pretty soon her hot body was rocking, her face was flushed, and about a third of that horse’s beastly penis was not only penetrating her sex hole, it was now also pulling her neglected clitoris into the fray.

This hot, bestial sex went on for a couple minutes without going any deeper. Penny’s whole body rocked back and forth, and her pussy was now getting pounded pretty good, more than it would just from her lover’s gentle thrusts. Her exertions made her beautiful, pendulous breasts bounce about from her tummy clear up to her chin.

The mismatched lovers, a 30-year-old stallion and a hot teenager, were still sexually frustrated. They wanted way more engagement in the best, and worst way. Then something wonderful happened. Penny looked forward, and there was Carol. She was also on hands and knees, but she was naked, with her ass raised up, her knees slightly lifted, and a big, black horse-cock banging into her vagina. Holy shit! Now THAT was going in deep! Indeed, the dark-haired girl was getting it on with a full-sized stallion, and she was really enjoying it! “Oh, Blackie! Oh, yes!” the horse-loving 19-year-old moaned. Penny’s eyes went from half-closed to nearly bugging out. That stud’s mottled, black and pink tool, a shaft nearly three inches across, was going inward what had to be a full foot!
“Oh, Blackie, you’re so HUGE!” Carol gasped as that great tool repeatedly thrust into her pussy, probing her girlish body so deep that Penny saw its bulge running up and down her soft tummy. The younger girl’s jaw hung completely slack. This was completely wild! There was a strong stallion with a stiff staff just fucking away like mad, and Carol was totally loving it!

Without another thought, the diminutive debutant gritted her teeth and reared back. Rip! “Aiiii!” she screamed long and loud as her hymen was utterly sundered, and stallion shaft was crammed up her oozy cooz about three more inches. “Oh fuck!” The ex-virgin with the horse fantasies gasped as she was actually stretched-out stallion wide in just one thrust! The pain brought tears to her bulging eyes, and yet… she only wanted more!

“OHHH!” Penny pushed back even harder as her stallion came forward again. “FUUUHH…” Her eyes watered as the rigid ramrod scored along her vagina and slammed right into her cervix. Then she lost her breath completely as that feverish fuck just… kept… on… going! Her pretty face agog, mouth open, eyes tearing, and tongue out, she only panted “Fuuhh, fuuhh…” as her radically widened vagina was now also stretched lengthwise.

Carol looked over and watched with glee as that one thrust went so incredibly deep that the young blonde’s expanded labia and clitoris folded fully inside, and her remaining mons wrapped around her symphysis. .oO(Wow. Just, wow.) Alphonse hadn’t gone nearly as deep on her first encounter. .oO(He must really like her.) She turned back and paid more attention to how she was also engaged with Blackie.

Penny’s stiff little love button sparked with over-stimulation. It was too big to squeeze inside her tight pelvis, and Penny just arched and moaned at the extreme stimulation. .oO(OWEEEE…) Her once virgin hole had just gone pony-big, pony deep, and hot like a firebrand as it was stretched up beyond her navel. She started to scream, but stopped. Her amazing, busty body was still pushing back, and still wanting more. She didn’t know right now whether this tight tryst was at seven inches or seventeen. All she knew was that she mated with a horse, and it was super-sexy, which made her awesome!

Penny’s wince turned into a wicked, womanly grin. She was fucking a stallion! The newly penetrated pony-lover quivered with smug pride at the very thought. Her vagina was still intact, except it was now really big, really deep, and really quite wonderful. Her pony pulled back. She gasped for air, exulted “Fuck, yeahhh!” and braced for a second thrust.

Carol smiled. She *could* tell how deep Penny had gone. That sexy stallion slut was amazing! …way too hot to ever stop. “Now, just hold steady, and try to relax…” the older girl coached. She did this with her own, rather larger horse, beaming with delight as he pulled back out and rocked back in. “Oh, Blackie!” she moaned as that great beast oozed in ever-so-slowly, thoroughly taking her aching pussy far, far deeper than that of the smaller, bustier girl.

Penny was aawestruck as she watched. Alphonse watched too, and they were both inspired. He too pulled back slowly, savoring the tightness and feeling reluctant to go more than halfway out. Then the wily beast drove back in, and Penny felt herself re-widened, bottomed, and then stretched in deeper and deeper. Alphonse was going for all she had.

“Wow, Penny!” Carol gushed as Blackie’s withdrawal let her breathe. That huge, achingly hard stallion was soon pulling the older teen’s tight labia out from her hips until their pucker just barely clasped his extremely wide glans. This was just how she liked it – feeling the whole length of a stallion using up every inch of her bestially deepened sex hole. This felt awesome, but her eyes were riveted upon the hot little blonde. “Ohhhh… Grrrl!” she shuddered, “You’re a natural… ummmmph!” Her praise became a moan as her elongated love channel again slipped and slid tightly along way over a foot of stallion schlong.

Penny watched this spectacle with inspired awe. Carol was doing a cock twice as thick, and nearly twice as long, and, she was *loving* it. “Mph! Mph!” The older girl mewled and twisted, arching down as the thrust of her lover’s cock bulged her tummy out well above her navel. She was clearly relishing her extremely lewd ability to take a huge horse so unnaturally deep, and she was actually trying for even more!

.oO(Ohmigawd! That much sex must be, like, totally amazing!). Penny shuddered with a jealous need. .oO(How did she ever become that big?) the younger teen wondered. Too bad her much smaller pony still made her innards ache something awful. Could she stand that much more pain?

Alphonse and Blackie had different techniques. Staying deep inside the smaller girl, the old pony kept pulsing inward. This rocked the tawdry tart, shaking her big boobs as he pressed for every last inch of her vagina. Meanwhile, the bigger, super-hung stud was now casually long cocking the country girl, working her tawdry adolescent body with 12 inch strokes.

“Yeah! Oh, yeah!” Carol gasped with each thrust. Steamy stallion stuffing had stretched her muscular vagina from human to horse-sized only with years of effort, and it was totally worth it. Having an enormous equine humping so deep into her taut body only pumped it up with pure, carnal pleasure. Her mother had introduced her to the secrets of stallion-sex about five years ago, when she even younger than Penny. She was in high school and starting to go boy-crazy, so horse sex was almost a distraction, at least until her first orgasm. She wasn’t a size-queen like her slutty mom, but the bliss was the bomb! Carol saw that this wasn’t true for Penny. That extra-busty little baby-doll seemed to really be a budding size-queen. Yes, she was now arched down like an angry cat, but she was also mewling her way towards what was sure to be an fantastic orgasm. Suddenly, the older girl was inspired with a need to really show what was possible. “Yeah, boy!”

Flushing with unusual lust, the nineteen-year-old horse-lover rocked forward and shoved back really hard. Squish! Horse-cock scoured her super-elongated vagina and socked her cervix. It wasn’t enough. She went wild, driving backwards again and again, until that tight ring finally opened. “UNNHHHGHOOOO!” Carol rocked back several more inches. She had done this only once before, letting horse-cock into her womb, but now she went even farther, taking Blackie so deep into her hot body that her belly actually bulged out above her ribcage.

Penny saw this and gasped “Ohmigawd!” Carol was making it like a mare! Somehow, that horse-loving girl had just taken a full foot and a half of raging stallion! Something clicked in Penny’s head, and a shudder pulsed throughout her already excited 17-year-old body. Suddenly, all pain was strange pleasure, and she just knew that her body could also do that.

Feeling the change, wily old Alphonse squeezed his forelegs around his neophyte partner and fucked her with real resolve. “Oh, oh, oh…” the gutsy gal groaned. She grabbed the carpet pile and banged back just as hard. Her big boobs bobbled back and forth, with nipples scraping on the carpet, as that stallion relentlessly pounded her vagina, stretching and retreating, and working to break open her womb.

Seeing the pony-pounded blonde’s new passion left the older teen feeling nothing short of amazing. Pleasure replaced pain for both girls, juices flowed, and their cheeks all blushed. Tandem sex was pretty damn good. “Yes, yes, yes…” both girls chanted, egging each other on. Both now raced to completely take their well-hung horses. It was then that the younger girl’s cervix started to open, and she began to admit the tip of her stallion-lover’s glans right into her womb.

Penny’s pony-pounded pussy quickly went quite slick and, all of a sudden, horse-sex was just fine! Her eyes saw fireworks, and her electrically erect clitoris felt amazing. That thimble-sized fuck-focus fired up with feral ecstasy. Her loosened boobs swing her enormously erect nipples along the carpet, and those sensitive spikes rippled with even more sensual bliss. This exquisite, whole-body ecstasy was quite unexpected. The steamy teen’s eyes drooped, her maw opened, and her limbs weakened. “Unh! Unh! Uhn!” she grunted lustily as she was stallion-stuffed with thrust after cunt-stretching thrust.

Penny’s vagina was now huge, hot and loosy-juicy, and it was only hankering for more… more…

WHINNY! Alphonse thrust in all the way! Pop! The short-girl’s tummy also bulged out at her ribcage as she got her needs fulfilled in spades! Her lover had just slipped his cock in super deep, actually getting his glans inside her womb, and her enlarged labia had actually emerged and completely surrounded his cock-sheath.

Indeed, this penetration was somehow even deeper than old Alphonse had ever taken either Carol or Mindy. Was this girl ruined? The gentle old stallion stopped and shuddered. His sheath was now so far into this lewd girl’s labia that his scrotum was slapping her ass, making his balls and her bottom both bounce up and dance around with immanent ecstasy.

And just then, in the quiet eye of a whorish hurricane, Penny actually came. “Aiiiiiiiiii!!!” she screamed as her brain flashed with an unimagined level of raw sexual energy. This intense climax transfused her, making her whole body flush a rosy pink, and making her astonishingly stretched-out pussy suddenly squeeze super-hard. The deeply penetrated debutante just rippled with epic ecstasy! Her cavernous cunt ran wave after cum-sucking wave of contractions from her labia, past her cervix, and right into her womb. Her face was alight, and her slender, teenage frame was rocking and rolling!

“That’s called cumming!” Carol exulted to see her young friend reaching such a amazing peak of pleasure. .oO(On her first try, too. She’s a little horse-sex hottie, alright!)

“AHHHH! CUH-CUH-CUMMMING-G-G!” the newly realized horse-slut stuttered with extreme ecstasy as her lover also peaked. Zoom – boom! His jizz bomb had jetted along her expanded love-channel, and her world was rocked off-kilter as it exploded right into her womb.

.oO(Indeed!) Carol had to look away. Penny was just too hot. A former virgin, now having a whole stallion, and experiencing only pleasure! That unnatural capability actually embarrassed the older horse fucker.

For the now capacious little blonde girl, a decade of education was lost. Somehow, her forward nature and wayward curiosity about horses had allowed this one crazy, soul-shattering climax to change everything. Now, in the whole, wide world, the only thing that mattered was horse-sex! Even Penny’s uncommonly large breasts flushed and swelled, slapping back and forth from chest to chin with the most wonderfully womanly feeling ever!!!

Alphonse was also feeling better than ever. Pshhh! Pshhh! That old stud stood and kept on delivering, sending jet after jet of hot stallion stuff straight into the infernal furnace of Penny’s babymaker.

“AHHHHHHH…” The overly orgasmic horse-fucker’s head went up. Her transfixed body was actively milking her lover’s cock with uncanny cunt ripples. Her mouth hung open until she ran out of breath, and then it stayed that way as her bespitted, bouncing body turned rather red. She was wrapped around an insane amount of horse-cock, her womb ballooning with horse jizz, and her hot little hips were doing the tawdry, timeless bump-and-grind for more.

Finally, the wayward waif almost fainted. “Ahhhhhhhh…” she gasped for air, quivering with electric ecstasy. She was in horse-cock heaven! “YES! MORE! MORE!” she cried as her puffed up womb bulged out the front of her stretchy, knitted dress.

Penny didn’t even know she had been holding her breath. She had peaked, but was still feeling what had to be the hottest, wildest, most female sensations ever. Her whole being, body and soul, was wrapped around a pussy so perfectly penetrated that it felt aglow. Her labia clenched and quivered around a thrusting stallion, her vagina rocked with sensual contractions, and her womb was simply magical, seemingly able to expand without limit as it boiled with jet after jet of hot, wet stallion seed.

Despite Penny’s addled imaginings, Alphonse was not a super-horse. He had done his very best to meet this teenager’s extreme sexual needs. Indeed, he was egged on by her glowing, mewling endless climax, but he was now spent. In all, he only came for about a minute, and, while that was directly into her uterus, it was still only about a couple cups. Once done, his penis quickly retreated back towards its sheath.

His young lover wasn’t at all ready to lose this peak of ecstasy. Her hollow tommy still felt aglow with unfathomable joy. Pleasure coursed through her whole body, and her senses echoed with the pulses of her lover’s penis, even as his tool shrank away.

Pop!, the softened, but still knobby glans dropped out. It reeled up the last six inches and Alphonse stepped away. The overwrought girl’s whole crotch now gaped open, with her labia repeatedly clenching in sluttish need. Still in the afterglow of her uncanny orgasm, Penny panted and heaved with waves of sightless, mindless lust until, finally, her weakened limbs left her in disarray upon the carpeted floor.

Carol thought Penny was in trouble. She almost exploded off of Blackie’s much bigger and more durable erection. Schlorp! Pop! Sproing! Sixteen inches of stallion stiffness popped free. It bounced about as his compassionate partner crawled over to cradle Penny. “Oh, dear! Dear! Are you all right?”

Penny was more than all right. She had just taken every inch of a stallion’s tool, and had a cum so crazy good that it was an equine epiphany. Taking a stallion as a virgin, and going so deep, and so hard, should have been agony. However, Penny was simply on fire with sexual delight. All that fucking, and stretching had somehow transformed her, making her into the horny horse-lover of her own, secret fantasies. Yes, her limbs were still weak, but her hot body boiled with bliss, and the beastly womb inside her tiny little tummy just quivered and ached to get fucked even bigger and harder, and filled up with even more of that sexy stallion stuff. Indeed, sluttish fuck-spasms rocked her torso, and her uncanny cunt did gut-wrenching flip-flops. Penny grabbed Carol and thrust her hot little hips the older girl’s body, wordlessly and fiercely begging for more horse sex.

Carol misread Penny’s spasms and feared for the worse. “Are… are you OK?” She hugged the sexy young thing, taking a secret thrill at the feel her precociously over-sized bosom. .oO(Was I like this? I mean, my first time was OK, but I didn’t get fucked even half that deep).

“Yeah…” Penny panted “…but an even bigger stallion would make me feel much, *much* better…”

Carol gulped, locked eyes with Penny, and shuddered as she saw the truth in those words. .oO(I have just created… a monster. A really cute, huggable, super-stacked stallion-shtupping… monster.) She smiled so wide it hurt.

****

Blackie eyed the smaller girl and pawed the carpet. He smelled her need. His big boner, still hard from fucking Carol without release, throbbed up and down to fill that need. “Hmm-P-P-FF!” he nickered. Penny reacted, and Carol felt her bosom thrust up and her legs spread. Her head pivoted, and Blackie saw lust as the gaze of her bedroom eyes locked onto his huge, bodaciously bouncing erection.

Penny burned with a hypnotic magic that she imagined building up in her lusty body as she eyed the bobbling boner. There stood a full-sized stallion, his stiff staff straining in her direction, and nothing to stop him. This should have scared her. It would have scared almost anyone. Instead, her soul only ached with desire!

“Can you hold me?” The young teen’s voice quavered as her soft belly rippled with sexy shivers.

“Yes.”

Blackie walked past the perverted pair, turned and approached their spread legs.

“Can you hold me, *for* him*?” Penny stirred, shifting atop Carol as they both rolled on their backs. She spread her knees more, and, to Carol’s amazement, Blackie quickly stepped in to straddle both their hips.

The older girl trembled with fear. “H-he’s wa-way too b-big, for you.”

“Oh, I… huh!” Penny gasped as her needful, seedful pussy clenched and shot out a gob of horse spunk. “…H-hope sohh…” she panted in a slutty whisper while shooting more hot cum from her gaping crotch. The 17-year-old was fired up to feverish levels even as her expelled juices drooled onto the larger girl below. Her hips lifted so her bulging, wide-open pussy lips grazed the stallion’s broad glans.

Whinny! Blackie felt that terribly hot flesh and his massive mating missile rammed forward. Splorch! its baseball-width glans further spread that girl’s already gaping labia, broached inside, and banged her so deep and wide that his flange caught at the constriction of her adolescent pelvis.

“Oh, yes, far too big…” Penny grabbed her spread breasts, pushed them upwards, and ground her hips. She was daring this new lover to press on, despite their mismatched anatomy.

Blackie snorted and rocked inward, straining against the little girl’s pelvis. “Yuh-yes!” she moaned, but she only slid back as the force increased. Sometimes, the cock really is too big to fit the hole. “Hold me tighter!” Penny commanded. Swept up by her lust, Carol lifted the young girl and braced her with her hands and knees. Blackie shifted his hooves apart and really rammed his huge tool at the needy waif with heedless passion.

“Ahg-g-g!” Carol grunted with effort, and grimaced as she felt a ghastly, grisly strain.

Pop! The young girl’s cartilage sundered at the symphyses, and that ferric, fist-sized horse-cock augured its way into her slim, teenage body.

“Guh!” Penny grunted. “G-gohhhh…” She moaned as the stallion-stretched sinews of her girlish vagina were horribly strained by such a beastly-big cock.

This fuck was so truly huge that Carol felt it pressing down on her tummy! She wept with both fear and joy. She knew this act was criminal, and yet, she resonated with Penny’s terrible, bestial need. Meanwhile, her stallion’s thrust continued with such strength that her back was pushed along the carpet.

“OHHNNNNN…” Penny’s eyes bulged and her mouth gaped as that inhumanly large glans scraped deeper into her tight cunny. It went in, inch by terrible inch, stretching the lusty little girl’s vagina super-wide. In fact, she got so big inside that her tender tummy was stretched up into a stallion-sized ridge! The distortion was painful, but it was also amazing! “OHMIGOD!” the sexy lass gasped. She was becoming as big as Carol! “Yes…OHH YEHHHSSS…” She gasped as that ridge went up and up, popped her bellybutton outward, and approached her ribcage.

The super-penetrated girl grabbed just her straining gut and groaned with lust as her lover pressed his glans hard into her compromised cervix. She didn’t know that getting so much bigger around would cut her hard-won depth so much.

Blackie felt Penny bottoming at a mere nine inches, and he paused.

“No.” Penny pleaded. “Take me deeper! Don’t ever stop!”

Carol practically had an orgasm at those words. What had she done to this girl? Would Penny die to get bigger?

Blackie bobbed his head up and down at those words, but he then rocked back instead of forward. .oO(No!) Penny tugged his forelegs. Disregarding this, the horny stallion pulled out until her pelvis lost its flare and his crown actually tugged her tight labia outward. Only then did he reverse and again spread her juvenile bones. .oO(Oh, YES!) Penny threw her head back and again touched her tummy. .oO(Yes. Make it hurt!)

That adamant stallion did make it hurt. He slammed the hot little hussy long and hard. Her mouth gaped as he really leaned in, cramming a tenth inch into her taut little body.

Carol sensed Penny’s willful desire for this and just held on. That big stallion again pulled all the way back and drove in all she could take, long cocking her resilient, juvenile cunt to extend that tenth inch. She smiled as that well-primed stud horse repeatedly ravished that tiny whore-child, taking her like a perverted pile-driver.

Slish! Wham! .oO(Yes!) Slish! Wham! .oO(Yes! God! Yes!) Penny exulted. An exceedingly erect, full-sized stallion was straining her sex flesh all ways at once… Wham! Deeper, taking an eleventh inch, which was just as deep as Alphonse had taken her.

Penny’s pain was much greater this time, for her vagina was now quite a bit larger around. She didn’t care. In fact, she reveled in it. This new tension left her feeling even more righteously raunchily tight than she had ever imagined. .oO(Being so super-tight must be an amazing gift to my lover!)

“UGH! UGH!” The budding size-queen started grunting out loud as a horse-glans repeatedly slammed her cervix. He wasn’t going any deeper, but he was stretching out the portal to her wayward womb.

After several minute of utterly wanton surrender, the young girl with her labia and clit somehow folded fully inside her body and up past her pelvis, felt cock was now bulging up not just way past her navel, but practically over her ribcage! Alphonse had also gone to this depth, but Blackie was so much bigger around that Penny remained painfully tight, despite generating enough juice to leave Carol fairly well soaked.

Suppressed by her sense of impending doom, Penny’s second, gradually building climax was still a long way off. She was paying more attention to how this vigorous ravaging was bouncing around her big boobies and driving air from her lungs. And then, the cataclysm happened.

Slish. Wham! Snap! Something ripped and, SCROOSH!, Penny and Carol both felt that small girl suddenly take several more inches of cock all at once. Screams were frozen on both girl’s faces.

Penny reached in and felt the penis bulge that was outside her ribcage. “Ohhhnnnnn…” The 17-year-old girl moaned with an uncanny delight as she realized how close that grand phallus was to the bottoms of her big tits. Her tough cervix had finally opened up! Pain was now pleasure as that hot core took in more and more horse-cock. Her fingers reveled in pure bliss to feel the gigantic cock-bulge climbing up towards her boobs. .oO(More! More!) Came her mental mantra as her fingers followed the deepening glans and others slid down to massage her violated cervix.

Blackie snorted and shook his mane. This girl was different! She was tight, but her womb was expanding with his force until she felt more like a big mare than a little girl!

Penny had the same sense of being ever more like a mare, and it was great! Her uterus was accommodating giant cock like it was expanding for a baby, while her shortening vagina actually gained even more girth as her over-sized lover rammed rapaciously deep.

****

Meanwhile, done with dancing and drinking, both parents walked up the driveway. Mindy liked Penny’s dad, and he was buying, so they had both over-indulged. In the Lyft home, conversation had gotten around to how much Penny liked horses. Her dad seemed to know already, so Mindy started by confessing that she had sex with stallions starting when she was only 16. “Does that bother you?”
“Nah…” He imagined her doing it, and was turned on even more. “Hell, I just got a hard-on thinking about it.” He went from holding hands to putting his arm around her shoulders. “Did you, uh, like it?”

“I loved it. I still do. I mean, I like it with guys, too…” she was worried, because Penny’s dad seemed like a real catch.

“How? Is it safe? I mean, how deep do you…?” His voice was husky.

She slipped a hand down his trousers and grasped his penis, ending the question. “You wanna see? Ooooo, you’ve got a pretty big one. I’ve done it for years, both before and after being a mom.” Now they were walking quietly past the house and out to the barn.

“So, can you deal with your daughter like, uh, liking horses?”

“I’d rather that than her liking boys. I mean, like, I was quite a rascal in high school.”

“I bet you still are.” she whispered. “I also bet that our girls are being rascals right now.” She slid the barn door open, and they slipped into the gloom. “The action is always in the back.”

Blackie was now fucking Penny just like he would a stout mare. He kept on humping forward, and her incredible sex well kept on taking it. Stallion-hard, and stallion-strong, his huge tool was forced in unconscionably deep – Hump! 15 inches! He snorted and pulsed. Hump! 16 inches! Both adults had expected bestiality, but not this. Penny was not struggling to take in half a pony. Nope. She was now getting long cocked by a full-grown stallion! And, she was eagerly accepting every inch of his steely tool! They stood agape, only watching as he pounded her belly, making it balloon upwards, towards her big breasts.

Indeed, both Penny and Carol’s hands were on that great, pulsing bulge, and their heads were rocked back in awe as their fingers were repeatedly treated to feeling that ridge growing up above that Child’s thorax. Hump! 16 inches! Both girls quivered at the fiery brink of ecstasy as this relentlessly excited stud horse gave Penny the fucking of a lifetime. Hump! 17 inches! He was now pressed in so far that her labia were gripping around the broad base of his rock-hard tool! The effort had been tiring, so he rested for a moment.

Penny had now taken the full length of a stallion, and SHE LOVED IT! It was simply the best thing in the whole world! That last hump, and that last inch, had put her over the moon with ecstasy. Then Bingo!, her cute little buns were grazed by her lover’s twitching, yet-to-be-satisfied balls.

“HNNNNNG-G-G!” The now totally horse-fucked teenager bucked with the throes of a truly magnificent, stallion-sized orgasm. WHAM! the grand spasm of ecstasy convulsed her sex organs and rocked her body upward into her lover’s fur. .oO(OMIGAWD!… OMIGAWD!… OMIGAWD!…) the big-busted baby-doll thrashed about, her soul totally surrendered to the momentous ecstasy of her body’s powerful response.

“Holy fuck…” her father whispered as he watched what had to be the most mind-bending, soul-shattering orgasm ever! His daughter’s mind and body seemed melted together with pure, heedless pleasure at having a horse-cock pounded so deep into her pussy that it’s tip now forced her abdomen into a bulged that went clear up to her big tits.

“See…” the tipsy older woman said as she gave him a hand job. “…I told you she would like it.”

“Unh.” The equally drunk dad grunted. They erstwhile lawyer was currently too Mesmerized to form a cogent response. His dick was out through his open fly and Mindy started a blowjob as they both watched. This display of wanton carnality seemed unstoppable. Blackie had gone back to egregious long-cocking, rocking way back and really pounding in, slapping Penny’s ass with his balls, and keeping her sexually mind-fucked beyond anything she had ever imagined.

“OMIGAWD!…OMIGAWD!…OMIGAWD!…” Carol also gasped and spasmed with her own auto-erogenous orgasm. She felt her stallion’s balls grazing over her mons, and she could also hear and feel Penny’s extreme pleasure at this outrageous taking, and that was enough. Her hands were feeling the depth and strength of Penny’s stretched-out pussy, and the motion of her big breasts, and… this girl was a miracle! The older girl also rocked up and down as she came, even as she braced the super-sexy child with all her might for even more action by the big stallion. She was now totally in love with Penny, and Blackie, and her strong loins pumped and burned with her most amazing orgasm ever. That was also when she saw her mom masturbating Penny’s father. At least her eyes took that in, for her strong body just kept on grinding away, shooting out cum-juice with the vigor of her staggering climax.

Wanting more contact, Penny loosed her boobs and wrapped her limbs up around her stallion-lover’s girth. Nearly foot-and-a-half of penis was rocking about within her body, which was itself squeezed between horse and girl in a hard ridge from her split pelvis clear up to her mashed breasts! And, she was clearly urging that stallion to be even rougher!

Feeling this pile of insane desire, Blackie whinnied, and started driving into this lusty libertine with everything he had. Bang! Bang! Bang… he rocked her full length, hammering into her orgasmic maelstrom with strokes well over a foot long. “YES!…YES!…YES!…” Penny gasped with the force of a stallion repeatedly rocking his sweaty fur along her excited breasts. Minute after minute she somehow enjoyed this impossibly deep sex. Her vagina, cervix and womb were all merged into one, great, mare-sized sex-channel, and she was just the sexiest girl alive!

Everyone there had multiple orgasms, except Blackie. He only worked himself up to one, insane climax. Penny’s dad came once from Mindy’s hands, again in her mouth, and then again into her cavernous, carnivorous cunt, before Blackie was finally finished fucking his daughter. “WHIN-N-N-EY-Y-Y” The stallion rose up, and his massively hardened erection actually pulled Penny out of Carol’s arms!

This was the epiphany for Penny. She was now flying like an angel and fucking like a succubus all at once. Her insanely intense orgasm overwhelmed all her other senses and thoughts.

“AIIIIIII!” Carol screamed and rolled away. She feared both that she would be crushed, and Penny would be ripped completely in half. However, that didn’t happen. Instead, that busty wench was just suspended in the air and bounced around on a stallion’s penis while he reared, pawed the air, and started pumping her full of his cum.

Mindy jumped off of Penny’s Dad’s cock and rushed forward, tugging him along. “C’mon! Grab his legs and guide him to the pads!” Holding her jeans, she ducked to the far side and grabbed a foreleg. Dad came up and did the same.

WHAM! WHAM! WHAM! The sexually stunned strumpet held on tight as the stallion she had driven completely crazy jumped up and down. Stabilized by the two grownups, his cock slammed her cunt without mercy. His cock was fully inside her small body and his balls danced a mad jig below her bottom. His long-delayed orgasm flooded his urethra, swelling it big and hard as summer sausage.

Tump-tump! His forelegs braced on the wall. Biff! Penny’s head and shoulders hit the padding. PAH-SHOOSHHHHH! His fully flared erection gushed a torrent of semen into back of her uterus.

“Yes, yes, yehhssss…” Penny exulted, arching and quivering with a chilling thrill at being fucked so supremely.

The old couple fell back onto straw bales and panted as the watched Penny puffing up. Indeed, her radically widened womb ballooned larger and larger, expanding between her and her horse, when her already overstretched vagina also started swelling. The flood of hot stallion seed was exceedingly large, far bigger than anything Carol had ever seen, or felt. She came in, rose to tiptoes, and hugged the fantastically well-fucked girl. “Now you know. You truly know…” she whispered, dabbing tender kisses on her face and lips.

Penny did know. She was now a sex-angel, with her limbs, face and overlarge boobs hugged against this incredible, god-like stallion! “Yeah…” (pant) “Yes. Ohh yesssss…” she reveled in the joy of her surrender, her pretty face flowing with tears as she accepted the love of her stallion and her mentor. She was now flooded utterly full and quivering with orgasmic satisfaction. Stallion seed had flooded down the length of her amazing sexing channel, swelling it with joyful tightness until it finally burst out. The wire-tight seal between her super-stretched labia and her lover’s adamantly crumpled sheath loosened just a little, and… “Oh, god, yehhhsss!” Penny brightened as well-squeezed dribbles of cum burst into flooding jets. It gushed back out from her stretchy gray minidress and sprayed about, flowed down her teenage thighs and splashed off her red chaps.

“OH!, OHHHHH! Ohhhhhhhhhh…” The now shrinking girl just moaned as her vagina rippled and drained. She was now shamelessly, utterly hooked on feeling this flash flood of flowing semen. Splashes oozed down her lover’s scrotum and dripped from his dangling balls. It pooled where her white shoes dangled at toe-tip, while its hot volume gave her a pleasure surpassing all her recent orgasms combined. If busty little Penny hadn’t been addicted to horse-sex a few hours ago, she certainly was now!

In one long evening, this secretly whorish wild-child had surpassed her ultimate dream – a stallion dalliance. Instead, she had surrendered so completely that her elongated sex-organs had not just accommodated a full-sized stallion, but had been blasted and bloated with so much horse-scum that it was like she was giving birth! Except that it wasn’t a baby sluicing along her super-tight sex-hole, it was a cascade of cum so huge that she just knew that she was giving her lusty lover his greatest pleasure ever! That knowledge was kismet. Her poly-orgasmic equine transformation was utter, total and irreversible! And she had done all that in only about two hours. This little girl was now just made for the pleasure of all stallions, the bigger the better!

****

Penny was still shaking with ecstasy when her fully satisfied lover took his hooves off the wall. A huge pool of semen had just gushed from her womb, rippled down her elongated vagina, and sprayed onto the carpet. Splat! She fell into it. Utterly stunned by two hours of intense orgasms, her quivering child’s body and ravenous, cavernous cunt visibly twitching with overwhelming ghost sensations of deeply surging equine phallus. The stacked, supremely satiated mare-girl just lay there in feminine disarray, hugging her big breasts and panting with joy.

Carol guarded the sexually wrecked little girl while the adults shooed away both stallions. The busty wunderkind with the horse-sized sex hole stayed curled up, hoping and praying that this would not be her last bestial act. Indeed, Penny was so well fucked that she could not even move, while her teenage friend, who was older and larger, at least on the outside, could take stallions repeatedly, and still walk. How is that possible?

That older girl barely strained to pick up the slippery little stallion-slut and take her to the douching station. She held her up and started sanitation and inspection. The big-titted baby-doll eventually recovered enough to stand and hold the rail as her grandly gaping sex channel was flushed out. “Wow, look how big she still is!” said Carol as she fisted the hose inward way up past her elbow. Penny’s gaping pussy was indeed huge. It was also so over-stimulated that it was on erotic autopilot. She only shuddered and gasped with pleasure as she now accommodated an arm, a hose and a great gush of cool water. “Oh, ohhhhhhhh…” She kept moaning and squirming her hips as Mindy stepped in expertly checked her for internal damage.

“She’s in great shape…” The Milfy woman declared. “I mean, for having just been a virgin, and then getting spread so wide, and taken so deeply, well, it’s a miracle.” Indeed, even Penny was surprised that she wasn’t killed by what just happened. Her hips were painfully sundered, but they could still hold her weight, sort of. She tried to focus all her core strength to stand, but she ended up needing Carol’s help.

“Don’t worry, girl. You’ll come to like having a spreadable pelvis.” Mindy whispered. “It happened to me while doing 2 stallions at once.” She smiled and walked alongside as Carol led Penny towards the house, where she was showered and dried.

Penny was puzzled, and finally asked “Both in your pussy?”

“Nah, Blackie was up my ass, and I got Big Mo up my cunt when Blackie drooped from a big orgasm.”

Penny pondered this. “But, how?”

Carol described helping Mindy as she helped Penny into bed. “They stand side by side, and I pull their dicks sideways to get her started.”

“No, I mean, how do I get my ass big enough to take a whole stallion?”

Just then, Penny’s dad’s pants filled with another big, bouncing hard-on. He had to go fap it back down while the women folk tucked his daughter in to a make-shift bed right there in the stable.

“Practice.” Carol grinned. “Lots and lots of practice.”

“Sweet dreams.” Mindy bent down and kissed Penny on the forehead.

****

Father and daughter never even drove back to the city. He moved his law office to Ojai and married Mindy. Meanwhile, Penny started home-schooling. That was mostly a sham, because that horse-humping little harlot was way too busy learning to pleasure every stallion they all could buy or borrow. The other gals also indulged, especially Mindy. She was almost as bottomless and insatiable, as Penny, but that bestial nymphomaniac, knew absolutely no bounds. That teenage horse-humper recovered overnight, with her pussy shrinking back down to nearly normal size. She felt a little ill at breakfast, probably from having her insides re-arranged and her intestines scrambled until they were empty. She played with her omelet, then wandered outside to check on Blackie. She was thinking about acting normal and going home, but her heart raced and her pussy drooled the moment she saw that beautiful horse.

Blackie felt the same when he saw the busty teenager. He whinnied and reared, starting to reel out some serious cock. “Oh…” she gasped, “Is he ready again?”

“Blackie is always ready.” said Carol as she came up. Indeed he was. The older girl helped Penny straddle a padded saddle stand that was obviously elevated and braced for bestial sex.

“Oh wow.” Penny’s heart fluttered. “Is this … safe?” she said with her ass up, head down, and arms wrapped around the girth of sheepskin.

“No.” Carol smiled and led the stallion to Penny’s backside. “Did you want it to be safe?”

“No.” Penny panted with fear and desire. Blackie slipped his cock past her labia and eased it forward.

“See, he can be a perfect gentleman.” Carol kept holding Blackie back until she was sure his penis was bumping up against Penny’s cervix, which was now surprisingly deep within her tummy. Then she had him do little rocking motions.

Yesterday had changed Penny’s world. A virgin the day before, she now found that having her vagina widened by a couple hands of horse-cock was like foreplay. “Oh. Oh, yeah…” she sighed, raising her pretty ass and rocking her hips around. “So… tight…” She arched her back and moaned. “Ohhh! Ooooo!” Her discomfort became pure pleasure. “Hav… Have him dooo…”

Bump! Blackie’s hard cock pressed into Penny, 9″, 10″… her cervix was starting to open.

“Do what?” Carol smiled and stopped Blackie.

“Mmmmmm…” Penny felt ready to swoon. This big, beautiful horse-cock was now poised to once again plunge all the way into her eager womb. “Have him do it hard… huuuu…” the tawdry teenager crooned as she felt her auto-erotic cervix gaping around some serious stallion cock.

Carol smiled. .oO(Stallion slut!) She knew what Penny wanted, but she waited anyway.

“Hoo, haa…” the 17-year-old girl was now so horny that she couldn’t even talk. “Ha, har, HARDER!” she finally screamed.

“Well, why didn’t you say so.” Carol slapped Blackie on the hindquarters. “Giddyup, there!”

Blackie whinnied, lifted his forelegs and rammed forward. “Aieeee!” Penny screamed.

Zizz! That stone-hard stallion shaft sizzled with tightness as it quickly took that teenager full length. Whump! it slammed that back of her womb at full speed and just kept going. 15″… 16″… 17″ 18″! It stretched her sex organs straight up through her taut waist and bulged them out under her cathedral-arched ribcage. Smush! His glans showed in full profile as his sheath gored into her labia and his scrotum slapped her juvenile thighs.

“Oh, yeah…” Carol watched. “She’s gotta feel that.”

Penny felt it all right. She felt her cervix flare open, she felt cock slide inside her baby-big womb, and felt her mare-sized vagina ripple over the bumps of the in-thrusting sheath, and she was in heaven, just like the horse-fucking whore she now was. Her abdomen bulged outside her ribcage to accommodate the most cock she’d ever taken! Blackie had just rammed into her all at once, like she was a hot mare, and it felt good! It felt amayy…

…ZING!!! Penny came. She came hard, like lightning! Her back arched against her stallion, her thighs clamped onto the sexing saddle, and her arms graced her lover’s forelegs. “OHH! OH, BLACKIE!” Her body shook with ecstasy like a summer thunderstorm, and her organs clenched while her skin flushed with her uncanny sexual response.

Blackie neighed, and shook, and bobbed his head. Ever so pleased with this rocket-ship responsive child, he slipped back and thrust into Penny again. And again. And, soon enough, that big stallion was topping that tawdry, hyper-orgasmic teenager like ten tons of pistoning sex. His boner, big as a baseball bat and lumpy as a tree-root, rammed back and forth, fucking through the barrel of her waist in fierce, foot-long strokes.

.oO(Oh, my.) Carol had never seen anything like it. Her mom also took all of Blackie, but not like this. The older, taller woman’s womb would shift up in her body, and the big horse would hump her diaphragm-deep, and she loved it. Penny was quite different. Not nearly tall enough for all of that cock, she was arched up, and her wanton womb was now repeatedly popping forward into the space between her immense tits and the sheepskin pad, and that obscene bulge banged her big boobs on each deep thrust.

“Oh! Oh! Oh!…” Feeling her incredible, exquisite expansion, Penny’s hung on and thrust back. Her gelatinous breast mounds jiggled back and forth as she was absolutely pounded by the big stallion. That truly grotesque penile bulge repeatedly lifting her body with its insanely large penetration. She may have been a virgin yesterday, but now this astonishing horse-sexing savant was caught up in a cataclysm of cascading climaxes.

In fact, Penny was so lost in a lusty, orgasmic haze that she felt only more and more ecstasy as her distorted female flesh repeatedly shrank and expanded around a full eighteen inches of cock. Each vigorously-hammered stroke finished with her lover’s sheath banging past her labia and oozing inside her wildly-widened crotch, and his big balls slamming into her tightly-curved thighs.

That stout stud felt his glans bang the bulge of Penny’s womb clear up to the bottoms of her big, jiggling jelly-bags! The adult couple arrived about then, and were both pleasantly surprised at how little Penny was making out on her mid-morning ride. The veiny profile of a ragingly erect stallion staff was piston-pumping through her whole torso, and she was being pounded into a quivering pile of mindless pleasure.

Blackie pounded Penny good and hard for almost an hour. He would usually cum quicker, but he wasn’t really recovered from having spent his balls so completely yesterday. Still, he just could not stop fucking this astonishing over-capable young girl. Her tightly elastic, extra-young body super-stimulated his organs, and her willing moans just begged and beckoned for more. Finally, he thrust into her as deep as he could possibly go, held there, and let ‘er rip! His new delivery of hot stallion jizz pump-pump-pumped up her wanton womb.

“OHHH! YESSS! YES, YES, YES…” The horse-fucked harlot arched up, gasping and screaming with unrestrained orgasmic joy as her abdomen again distended with horse semen. This was the moment she now lived for. Her eyes saw stars, her body shuddered and writhed with ecstasy, as first her uterus, and then her vagina swelled to the diameter of a softball. Only then did her wire-tight labia stretch enough to loose that feral flood.

Pshhhhhhh! Horse spunk shot back out of the thoroughly horse-fucked adolescent. It splashed on her stallion’s scrotum, and back to his legs, and out to her legs, and it all ran into puddles on the floor. This was far less semen that yesterday, but Carol was still amazed. “Damn, girl! You just fucked ol’ Blackie deeper than even my mom, and you’ve just coaxed more cum outta him than I’ve ever seen, even when he’s fresh.”

Taking that as the highest possible praise, Penny just laid there and beamed. Pride only amplified her orgasmic afterglow, making her feel like she could light up the whole barn. Yes, her arms and legs ached from their exertions to help her stallion-lover again rearrange her sexy innards, and her abdomen churned with nausea from being so utterly penetrated and pummeled, but, that round of hide the sausage with Blackie was the fantasy fuck of a lifetime. She knew then, more than ever, that she would only want more… more… more of this incredible stallion sex.

****

Penny and Blackie quickly became the most amazing couple. He was so taken by their engagements that his penis recovered quicker and quicker, and then it just stopped going soft at all in the presence of this incredible, unstoppable lover. He just couldn’t ever get enough of this supremely sexy young girl. He pumped Penny long and hard, blasting her day after day with uncanny cascades of cum each time, and then he was ready again, even as her gaping cunt was still expelling semen. Even when utterly slagged by her orgasmic exertions, Penny felt her lover’s revivified erection and was aroused again and again. Her muscles burned and her guts churned as much as any Olympic athlete after a training session, and yet, she was always ready to go. “Help me hold on, Carol.” she would sometimes say while both resting and fucking. However, her body, and especially her cunt, grew stronger and more resilient with this extreme exercise. She spent less and less time laying with her weak limbs hugging the sheepskin on a stand designed to hold a larger woman, and more and more time arched up and thrusting back, at least until Carol got tired of her hogging all the action.

“You’re just too greedy.” Carol was serious this time. She tugged the reluctant Blackie back, pulled Penny off the stand, and mounted it for herself. “It’s been weeks and weeks, and now it’s my turn!”

Whinny! Blackie still liked fucking this other girl, too. He lifted his forelegs and pranced forward. Easing over her broader backside, he felt his penis engage her damp pussy, and then he thrust in.

“OOOOPF!” Carol gasped as her favorite stallion slammed her cervix deep in one thrust. “UNH! UNH! UHHH…” She grunted as his bold strokes banged her vagina twice, stretching it deep into her body, then ramming through, straight into her womb. This was not the gentled beast she was used to. He was rougher, and harder, but, emulating Penny’s face-down technique, she held on, raised her shoulders, and arched her back. Fur buffeted her hair forward as his thrusts stretched her womb, moving it down. Carol felt her guts shifting and was worried, but she held on, bit her lip, and keep going. This wild, willful sacrifice did something to her mind, driving out fear and flooding it with an amazing sexual pride.

“UNPH!” She grunted again as adamant horse-cock drove her womb against her upper abs for the first time. Then, in a few more strokes, she felt her abdominal wall really bulge outward. .oO(Ohmigawd! Yes! I’m doing it like Penny!)

ZING! Carol convulsed with an amazing orgasm. “Omigod, Omigod, Omigod…” She chanted, finally taking more pleasure than discomfort with each thrust. .oO(Yes! Ruin me!) She went wild, starting to really push back as her long-cocking lover thrust in ever deeper.

Wham, wham wham… Blackie hammered his cock into the wildly cumming teenager like never before. Soon enough, his cock head had bulged her abdomen out big as any softball, and his balls were now slapping into her thighs for the first time.

Va-VOOM! Carol launched into a second, even bigger orgasm even before the first had faded. .oO(Oh Fuck! Ohmigawd! OH! OHHH!) Now she too was completely lost to the pleasures of perfect surrender, and she only saw stars and heard angels, as this big, unstoppable stallion rode her teenaged body. He was merciless, banging her like she was a great-big mare, and she was awash with ecstasy. This was the first time she had ever truly taken all 18″ of his big cock, but it wouldn’t be the last.

At first Penny watched with admiration as Carol got herself so completely and thoroughly fucked by the girl-obsessed stallion. This one was bigger, and stronger, and now she too was an utterly awesome sexing receptacle. That cowgirl may have made love to this beast many times before, but this was different. Following Penny’s example, she was now completely sundered, not only taking all that stallion had, but also bucking back into his thrusts and going totally wild with bestial lust.

Mindy and Penny’s dad had heard the commotion, and they stood stunned as they watched Carol fucking away with Blackie just like Penny did. Both girls were now sexual titans, just like Mindy had been, and still was. This stallion sex-machine was moving his body in fully foot long strokes, and she was swinging back and forth for more, so their pistoning passions were rapidly showing and hiding a good 15″ of this bulging, rock-hard penis.

SWISH-SLAM, SWISH-SLAM, SWISH-SLAM… Girl and horse went at it with total abandon for about 20 minutes, and then Blackie was ready for another of his cunt-flooding deliveries. SLAM! He took her full depth and then some, making her belly bulge out a full hand above her sternum. SQUIRT! He filled her womb with seed. SQUIRT! SQUIRT! he blasted her again and again, making her body swell almost quite like he now did with Penny. Carol’s labia were looser, so his stallion seed just flooded out and splatted into the already copious puddle below the bench.

“Wow, girls. You really got Ol’ Blackie into a fuckin’ frenzy!” Mindy eyed what looked like quarts of cum pooling on the floor. Then she looked at the horse’s body and muzzle. “Poor Blackie.” She sidled up to him and hugged his neck. “Did these nasty girls get you into a frothing sweat? You just back off, and we’ll get some carrots, oats and water.” Indeed, that stud horse was pretty tired from almost an hour and a half of his favorite pastime.

****

From then on, both Penny and Carol were full-length horse-fucking fanatics. The younger girl’s relentless vigor at hide-the-horsecock soon had her pussy perfectly toned to fuck even bigger stallions. Her dad was happy to oblige. He was really into this scene, and he worked tirelessly to get ‘his girls’ larger and larger horses. He searched around and bought the hottest, horniest and most hung studs he could afford. This was good, because, while Mindy was initially both wider and deeper, his little teenager was now a fanatical size queen. Her juvenile hips would widen as needed, and her now meaty love-mound would squish open and then draw up inside her pelvis like an accordion. Its expanding folds let her cervix and womb migrate so far up into her muscular torso that her titty-deep bulge looked like she was riding her own cunt. This astonishing skill took constant practice, and it changed Penny’s whole appearance. Even when empty that otherwise un-chubby teenager looked like her muff was both puffed and stuffed, her waist was a meaty channel, and a muscular hump went up to join her breasts. She utterly loved walking about with her great-big cunt squishing around within her tight little body. That huge sex-tube was like having her own super-power.

Penny also like that her breasts were like another superpower. They were fun back when they were just overlarge, but something about her horse humping hobby was making those female fun bags grow without mercy. Her dad speculated that over-stimulation was making her hormones go wild, but Penny, only loved each new cup size. Her two bimbo breasts ballooned a big as her own, blonde head, and they were just amazing, thrusting straight out, with her erect nipples projecting out even more, and, well, it was awesome. They sagged somewhat, and wobbled about wildly at times, especially in the shower and bedroom. However, out in public she had taken to wearing a custom bustier and body shaper to keep her titties towers thrusting up and jiggling around at shoulder height, her thighs and booty well separated, and her body cylindrical, so her torso was shaped like one, great-big cunt. Adding to all that, her body changed dramatically when she was thinking about her next stallion. Rising lust would expand her awesome pussy until it spread out beyond the 3″ Velcro strap, and the same excitement would also swell her breasts, starting to fill them with cup after glorious cup of sexy milk. This effect was so pronounced that her boobs would actually lift off of her bustier up towards shoulder height, and her nipples would spring out big and long enough to grab like hoe-handles.

.oO(Oh yeah!) Penny loved her super-boobs. Sure, her unruly, up-thrust bust and resulting tiny waist were now dangerous on the street, quite capable of causing fatal accidents, but those hyper-sensitive orbs were great fun out in the stables.

****

The talented, tawdry teenager still had one problem. Her ass was just too tight. She worked hard on it, and she could now enjoy anal sex with their pony Alphonse, but she wanted more.

Carol’s mom was the real queen of that delight. That marvelous MILF could butt-fuck full-grown stallions and cum like it was the greatest thing ever, and Penny was quite jealous. Now she quivered with anticipation. Today was not just another training day. Today, she would take Blackie all the way up her backside, or die trying!

She helped Mindy with her enema, both because they all liked to be clean inside, and because it kept down her arousal in the presence of so many stallions. Milfy Mindy lifted her bum and easily took in the foot-long nozzle. Then she coaxed Penny into feeding in hand after hand of the stiff hose. “Oh, yeah! Now pump it, girl. That’s it… in and out… in and out… Ohhh, yeahhh!” The grown woman shuddered with pleasure as Penny’s hand slipped into her bowels. “Oh, darling. Your fist is so nice. Oh, ohhhh…” she moaned, first pushing back for more, and then springing up and hustling away. “Blackie, baby, here comes momma.”

Blackie snorted and pranced, clearly eager to fuck his equally eager owner. Mindy stretched out atop a stout ‘saddle rest’. Her knees bent, and her ass gaped with readiness. “C’mon, Blackie, momma needs this.” The sable stallion stepped away from Carol and straddled her mom. Penny watched closely as that stallion humped forward and his cock struck too low. Shzzzip! He slammed it home, taking Mindy’s pussy in one huge thrust. “OH! SShhheeee… UMPH!” Mindy bit her lip and moaned as her vagina went from slit to slutty chute in a trice, and she groaned aloud as that horse slammed her cervix. She wasn’t used to having a stallion she had trained be so rough, but her body took it well. .oO(Damn! That teenage sex-machine is ruining my best horses.)

“Oh well, maybe next time.” The teenager grinned as her bust began to swell in earnest. She loved to watch a good stallion pussy-pounding, and Blackie was one of the best. He started topping Mindy like she was a stout mare. He rocked over her with real vigor, and it wasn’t long before her cervix and womb were both beaten open and plungered by pistoning penis. Big ol’ Blackie was able to repeatedly bury all of his 18″ cock into that horse-loving woman’s luscious body, even to the point where he was skinning back the sheath like he did with Penny. Blackie usually had a slow fuse, and Penny knew tricks to keep him going for almost an hour, but Mindy did the opposite. She just opened up and relaxed, her face agape with pleasure while that dear, equine pile-driver slammed away at her tough, well-trained sex-hole.

“Yes! Yes, boy! That’s it! Momma knows… how you like…” Mindy stopped and gasped, rocking and rolling her way through an intense, long-lasting orgasm. Her method was different internally – she took that whole length of horse-cock up the middle of her body. This meant her stallion’s huge glans was now pounding her diaphragm far up into her thorax, pulsing her lungs and making it hard to talk. Not that she needed to. She and Blackie had fucked like this dozens of times, and she treated him to a great, big, ball-lifting orgasm that had his spunk spraying back out from her loose, ragged pussy.

“Oh, Blackie. Oh yeahhh…” Mindy relaxed for a moment as he pet stallion’s erection waned within her body. Then she looked at Penny. “Ok, child. Stop diddling yourself and grab his dick! Stroke it some, and then shove it back in. This time, make sure it goes straight up my ass.”

Penny did better than that. She caught the retreating phallus as it dropped from Mindy’s pussy and lifted it into her drooling mouth.

“Mmff! Thff wfff tff minfff.” She tried to say it would only take a minute. Indeed, her mouth sucked in that softened whanger and she swallowed the last dribble of cum before sucking the whole thing down her now stretchy throat. Zing! Penny’s eyes bulged as that glans both elongated and nearly doubled in diameter. It plunged clear past her collar bones, and threatened to get stuck. “Uhhhnnnn…UMPH!” The phenomenally busty teenager pulled herself back to reveal a boner every bit as big as the gape in both of their huge pussies. Plop! She pulled the horse by his big cock and stuck that flaring glans right against Mindy’s puckering asshole.

“Oh, yeah girl! Keep it aimed right there…” The older woman swirled her ass around and panted as her revitalized lover started pounding in. This went a lot slower than their first taking, which was okay with Penny. She rocked back and grabbed her towering titties as she watched that mommy’s jiggling backside getting banged wider and redder. “C’mon baby, make me take it…” Mindy bit her lip and held on as that stallion really rocked forward. Finally, with a tight, skreltching noise, that cock went from just barely getting the tip inside to quickly shoving almost a foot of phallus straight up her pristine poop-chute. “Oh, fuhhh… fuhhh…” the older gal panted and wiggled. Her face lit up with a special pleasure as that stallion pounded her rump deeper and deeper. “Fuhhh, fuck-yeahhhh…” she sighed as her lusty lover filled her bowels just as deep as he had just taken her vagina.

This pleasure was different for both woman and stallion. Blackie somehow knew that this wasn’t the right way, but he really liked how it felt. Mindy also liked the feeling – there was a special closeness and heat with anal sex. In and out, in and out, that sturdy stallion set a strong example of just how long and loving he could be with his second coming.

This sexy display was so feral that Penny pulsed with passion. Her muscular pussy blossomed out like a big flower. Lust-juices drooled out like honey. .oO(Ooh. His second cumming will take even longer. At least, his second today.) She grabbed her nipples and remembered fondly how she had completely relieved this stallion of all his spunk just last night. She shuddered with endless sexual need and felt the compacted mass of her cunt shifting about within her ripped abdomen. Her breasts swelled upward as she thought about fucking Blackie. She casually leaned back and popped those orbs out over her shelf-like bra. Now big like volleyballs, each tit was crowned by an obscenely erect nipple long as her whole palm. She just loved getting pumped full of horse spunk, and she was jealous, because Blackie was the best hoser by far.

Meanwhile, Carol led in a stallion named Kegger. “Hope you’re ready for more stallion than ever, ’cause this guy’s he-uge!” On cue, the gigantic Friesian-Percheron cross bobbed his head and whinnied so loud that Penny felt air pulsing in her lungs. She turned around and gasped until her breath was gone. He was magnificent! Blacker than Blackie, this powerful stallion was bigger than anything she’d ever seen. He snorted and tried to rise against his reins. “Whoa, boy, whoa!” Carol commanded, but it was no use. She let slip the leads and just waved a hand at his eye-level cock. It was he-yuge!

Carol eyed Penny’s insanely erect chest, widened haunches and swampy, oversized crotch. “Well, look who else is already all worked up.”

Penny mind was blown. This stallion was insane! His big dick looked like a tree hanging off the back of a logging truck! Everything else was almost equally wondrous! His nut sack was truly huge, like two footballs in a gunny sack. His muscles bulged a rippled, especially under the shiny fur of his hindquarters. “Fuh-fuck, Carol, where did you get hu-HIM.” The extremely stacked, and awestruck horse-slut locked eyes with the big beast, and she was Mesmerized. She was suddenly so horny that she could even breathe, and so horny that breathing didn’t matter.

“He’s from Brazil, by way of a belly-riding school up above Malibu.” said Penny’s father. He was off to the side, next to an extra-tall strawberry blonde that looked about 20. “We won’t get to keep him, but I bet Kelly here that you could handle him.” The blonde just smiled. “She’ll show you how to get into your harness.”

Penny had heard of that, but had never tried it. Minutes later, with Blackie still ass-fucking marvelously moaning Mindy in the background, the super-stacked size-queen leaned forward and pressed her now stiffly enlarged breasts into the new stallion’s chest.

“Ohh, yesss.” she closed her eyes shuddered, paralyzed by the thrill of just hugging such a magnificent animal. This sex was going to go beyond incredible! Snap. Kelly clipped a ring in her cleavage around the wide strap running down from the horse’s neck yoke. It was like an equine zip-line straight down to stallion sex-land. “Well, this is nice…” Penny practically purred as she raked her erect nipples back and forth across that rippling, sable coat.

“Yeah…” Kelly casually fondled her own, less-massive chest erections. “And these belly-riding bustiers keep our hot boobs up and in contact all the time. That keeps your hands free for pulling these.” she held up silky loops that draped down behind that giant beast’s forelegs. Kegger’s normal rider smiled. She was 6′-2″ tall, with a torso made extra-long from six years of practice and training. Yes, this cherubic little girl was super-hot, but too bad she was so short. “Now, just keep your legs together and slide down.”

Penny smiled as her sexually flexible hips squeezed together to slide between Kegger’s spread forelegs. She had gone fully bestial, letting the hypnotic power of supreme sexual ecstasy drive strange changes within her body. Her up-thrust udders jiggled to a stop as Carol expertly guided her hips home around that giant horse-cock. Plop! The huge knob pressed her thighs apart, widened her puffy crotch, and slapped home.

“Oof!” Penny gasped again. She hadn’t anticipated slamming onto that stallion’s glans while her hips were barely past his shoulders.

.oO(Ohmigawd! How long *IS* he?) She lifted her knees up around Kegger’s torso and shimmied. “Unnnnh!” she moaned with effort, but this adamant glans was not about to just slip inside, as it was easily four times wider than her sizeable vulva. .oO(Ohmigawd! Ohmigawd! Ohmigawd!) she started to panic.

Kelly smiled.

.oO(This little girl might not even take the first inch!) She thought as she wrapped the rearmost silk leg loops around the teenager’s petite ankles. She knew exactly how big Kegger was, because he was measured every time they performed together. “There. Now spread your knees and rock your hips. It’ll help…”

“Oh! Ooooo….” Penny the stallion-slut didn’t need any instructions. Her hyper-sexualized mind flashed with the image of a fantastically big horse-cock, her bimbo body flushed pink, and her pelvis started to spread open. Her hips grew wider and wider, while her juicy cunt became quite cavernous. “Oh! Ohhh…” the teenager cooed with rising lust. Getting herself spread out so fucking huge had been the best thing ever! She had progressed from one horse to another, bigger and rougher each time, always wanted more, and this was just another step on her life’s journey.

Kelly was amazed. Only she had ever taken Kegger, and she was the world champion. Could slutty little Penny really match her record? She knew several girls whose could expand like this, but this girl was a wonder – she had just rippled out from a plump slit to a fucking cave in a few seconds. Plus, any fear she had was now gone. The smaller girl’s face showed only fervid lust as she worked her cunt downward.

Of course, Penny just *knew* she could do it. She hooked her heels against the silk loops and wiggled her body even lower. Slowly, delightfully, her vagina reached the size to admit the broad tip of that huge penis.

Feeling this surrender, Kegger rocked forward. Splorch!, his whole, humongous, nearly-head-sized glans slapped instantly inward. Bump! that girl’s sunken belly suddenly bulged outward.

“Oh my gawd, she did it!” Kelly gasped and pointed at the uncanny distension of Penny’s once-flat abs. Was she torn? Would she ever make it back to normal?

Penny only smiled. For her, getting super-huge *was* normal. Her sundered hipbones had opened wide, like clamshells, and she loved it! This was her superest, hugest ever! Her super-muscular labia now grabbed tight as a hangman’s noose around a head-sized glans! This almost impossible penetration was all so super-plush that this tiny size-queen was transported right to the brink of an outrageous orgasm. Even her huge boobs were now wedging together to slide between the stallion’s forelegs. Yep, this fuck was delightfully massive. This cock was longer than her whole torso, and she wanted ALL OF IT.

Squeezing her vagina to carry her weight, Penny tucked her lover’s forelegs under her arms and shouted “YAH! Up, boy, UP!”

“WHINNY!” The gigantic horse reared. His cock broached inward as he did. This forced Penny’s tummy outward, bellying it up into an astonishing mound that ran clear to her ribcage. Kelly’s jaw dropped. That formerly super-slim body was lifted by its core strength until its uncanny owner was stretched over and around the first foot and a half of that Percheron’s powerful penis.

“No, no!” Kelly shouted. “Down, boy, down!” Her face was now at Penny’s clenched thigh. It was rather smaller than her expanded cunt, but it also rippled with well-defined muscle as that whorish wunderkind wriggled her body and managed to slip down a tiny bit more.

“Atta girl!” Penny’s dad shouted encouragement. Then he said “That’s only her vagina. Now watch. She’s gonna do her womb…” as an aside to Kelly.

.oO(Holy fuck – was I ever wrong! This girl is a sex goddess.) Kelly was so impressed by the cascade of cunt muscles visibly rippling under the child’s skin that she stepped up and pulled the silk strap around her right hand. “Hey, help her out over there.” she said to Carol, who was already stepping up to the other side. Kegger stood, bouncing at full rampancy as they quickly looped Penny’s hands and feet to his sides.

Penny liked how these belly riding straps gave her so much control. “Yeah, baby. Now we can really dance!” she exulted, pulling her face into the plushness of her big boobs. Those fleshy orbs were now mashed together by Kegger’s forelegs. They pressed her head back as he panted, and their bouncing motions worked her enormous nipples up and down, going as high as her forehead.

Kegger felt Penny’s supremely strong pussy grab the first half of his gigantic erection. He was quite excited by how it was pulling him in a tiny bit deeper as she worked herself around on it. Well, he knew what to do to girls that lose control! He whinnied, pawed the air, and started really leaping up and slamming down.

“OHHHH!” The perverted size queen gasped and took another inch. It was great fun, but she still thought she’d prefer straddling a stout stand to be treated just like sturdy mare. “OHHHH!” She gasped again, leaning back so the next inch of cock popped out above her solar plexus. Her big boobs dropped down around the obscene bulge. “OHHHH!!” the lusty, busty, lass was doing her mare-girl thing bigger than ever, and she was rewarded with stunning sexual ecstasy as her cervical ring passing down around that whole cockhead.

“OHHHHH!!!” her face radiated pleasure as the next thrust slipped her down to where the sexy collar of her cervix gripped into the depression behind the flange. That entire, head-sized horse-glans, now lodged within her womb, was sandwiched by the ribcages of horse and whore front to back, and squeezed left to right by the jiggly bottoms of two massive boobs. This penetration was huge! Penny LOVED that she was now nearly transfixed by over two feet of humongous, veiny erection. Her stallion’s cock now throbbed with power as he continued to bounce. In return she arched back even more, letting go of the silk straps and grabbing her great, multi-inch nipple spikes. She tugged and squeezed, helping her enormous, more-than-head-sized breasts dance about while her body was slapping up and down, being driven into by her lover’s massive cock. Her fists were raking distended tips of her crimson nipples through his glistening black coat.

Penny was happily plateaued at this violently bust-rustling full-torso horse fuck for many a minute of stunning thrusts. Loosening her limbs, she urged her mount to his most unrestrained level of exertion. This was the one dance older than music itself, and she was calling the tune. A cockhead, quite as broad as a rugby ball, was now socking up and down inside her womb, fully outside her ribcage and within her deep cleavage.

“Oh, Oh, Ohhh…” Penny gasped at every thrust was a little more vicious. There was nothing in the whole world she like more than a great, big stallion fuck, and this was the biggest one ever, or it would be fairly soon. “FUCK! FUCK! FUCK ME ALL THE WAY!!!!!!!!”

WHUMP! The ground shook as the 2000 pound stallion went fully airborne and then slammed his salad-plate sized metal shoes adamantly into the earth. “OOF!” breath was pounded out of Penny as her lover’s giga-cock suddenly slipped a whole bunch deeper, driving along her thorax and poking up above her boobage.

.oO(OH MY FUCKING GOD!) thought both Kelly and Penny. Kelly was stunned, while Penny was exultant! The unconscionable size-queen erupted with a crazy-good orgasm! Her face glowed with supreme delight at having the muscular tunnel of her cunt filled with horse-cock up through her boobs clear to her chin. Her womb had now stretched lengthwise more than a foot, which let her boob-festooned torso slip down countless more inches. Now her swollen, super-sized labia pressed against the spongy width of his sheath. THIS was REAL horse sex. This was…

The stallion’s extremely strong hindquarters drove their bodies up and… WHUMP! The ground shook again. The sexy folds of his sheath and her labia mingled together. “HUNNNNNFFFF!” Penny spasmed with another orgasm, one that was truly cosmically mind-bending. That giant, adamantly erect cock forced her pussy lips and pelvis to a whole new level of stretch. The now 17-year-old teenager, who was sexually altered by endlessly surrendering her supple body to larger and larger stallions, was now in full-body climax! Her mega-cunt felt like a radioactive sex-core. One great bulge now went out from her mons clear up to her chin, and still that stallion had more to give! The hyper-sexual juvenile’s huge labia and clitoris had now folded fully into her body, letting her slide down until that giant, ever-widening stallion shaft had her stretched wide as his hooves.

.oO(FUCK YEAH!)

WHUMP! Three inches more, and that skin bulging before that huge organ actually tweaked that girl freak’s cute little nose.

“Ohmygawd! Will he kill her?” Now it was Kelly’s turn to feel fear.

WHUMP! Three inches more, and “FUCK YEAH!” Came Penny’s muffled voice.

Her dad turned to Kelly and said “Maybe you should ask whether she will kill him, instead.”

WHUMP! Penny now pulled in and kissed the penis-shaped bulge before her face. She was on top, a ginormous stallion was on the bottom, and their super-hot mating organs were the sexual axis at the center of their universe. Her face was scarlet with ecstasy, her mouth was lolling open, her tongue was out, and her eyes were rolled up and crossed.

“Yeah, don’t worry about super-slut-girl.” Carol intoned. “You should just worry about Kegger overtaxing himself.” she nudged an elbow into the lanky belly-rider’s ribs.

Kegger dropped back down, shuddered and panted. He now had nearly three feet of cock rammed inside this girl, and her signals were only Harder! Deeper! Faster! The champion belly-riding stallion started rocking back and forth as hard as he could. Their cross-species engagement was just too tight. This bulge of his cock head proceeded to pulse in little stitches through the teenager’s massive bosom and between her face and his furry chest. Forget belly-riding – this was not nearly enough action. He trotted over to a well-padded stand, reared, and crushed Penny down into its deep sheepskin. SLISH-POOM! SLISH-POOM! SLISH-POOM! He fucked her tiny body with his draft-horse strength.

“OH GOD! OH GOD! OH GOD!…” Penny chanted with total ecstasy as that gigantically flared flange repeatedly ripped back and slammed forward, fucking her cunt so fantastically far up her torso that its bulge popped out above her cleavage. Slish-POP! Slish-POP! He super-plush labia vibrated with tightness as they conquered the cunt-expanding taper of Kegger’s impossibly large penis to finally start slapping into his balls.

“Undo her legs!” Carol shouted over the muscular squelching of this hyper-hydraulic sexing. She indicated Penny’s short, shapely gams and took one from the silk strap and stuffed it into her own cunt. Milfy Mindy doffed her jeans and did the same thing. Holding Penny by her shapely ankles and riding her toes like twin cocks, they both held her ankles and leaned back, cumming madly as they savored the thought of adding their own weight to pull Penny’s even harder into this piston-like pounding.

“YEHSSS, YEHSSS…” Penny gurgled with the air forced out by each massive thrust. Now insanely orgasmic, she hooked her arms around the unnatural bulges of her breast flesh and whispered “Pull my nipples, too…” She sank back into roiling waves on a sea of ungodly bliss as her father and Kelly came up and did her bidding. “AHHH!’ AHHHHH!! AHHHHHHHH!!!!!” the hyper-sexual nymphomaniac screamed as she creamed and creamed and creamed to feel how her super-muscular cunt could now take 30+ pounds of pounding penis. Her fantastic breasts were shooting out great jets of steamy milk, her cunt was bubbling with a frothy Champagne of her own cum, and her voice filled the barn with such orgasmic joy that Kelly felt a little ill.

Penny had achieved her ultimate climax. Her body was now completely reshaped into one cavernous cunt-muscle from eager eyes to taut thighs. Her sexuality now completely encompassed and delighted the passionately pulsing penis of the biggest, most generously hung stallion ever known. Furthermore, her cataclysmic orgasm was truly monumental, filling her every nerve end with electric bliss, like her whole body was cumming everywhere all at once. From toes to nose she was now nothing but the total embodiment of fantastically feminine sex! Even her nipples were up and cumming like full-sized phalluses.

Kelly was aghast. She was way taller, much older, and had trained in the exquisite art of belly-riding for six years. However, This unholy, whorish young horse-fucker has too fully and easily surrendered herself to the extremes of equestrian sexuality. She was worse than useless, for she was even now ruining Kegger’s discipline, driving him to obscene excesses from which he might never recover.

“WHINNY!” Kegger clearly did not think he was being ruined. His sweaty muscles glistened, his strong heart raced, and his big balls danced with joy. He pounded Penny with all his great strength, and ended in a epic thrust that stretched her distended womb from mid cleavage clear up to her forehead. Then, holding forth, his urethra blossomed bigger than any man’s whole cock, and KER-SHOOSH! he started hosing her with his voluminous seed.

Kelly watched that girl’s womb inflate with obscene gobs of stallion cum and was both astonished and disappointed. Penny was the completely accomplished slut-goddess of all horse-fucking, but no one could ever surrender so utterly and still retain any control over her mount in a belly-riding contest. She was barely able to watch her giant competition horse finish fucking the oversexed girl. Both girl and steed were cumming so hard that they ended up nearly unconscious from pleasure and dehydration.

Both wanted to fuck even more, but that had to wait a week Because Kegger need time to recover. Penny, on the other hand, was doing her daily doubles, with one stallion up her ass and another down her throat that very same afternoon. Both were big around as beer cans and so long they passed in her middle, but, even together, they were less total cock than Penny’s still gaping cunt had just handled all morning with that very special stallion. That experience, of finally taking a cock that was bigger than her whole body, had freed her mind of all concerns about appearance and propriety. The stallion at her mouth was one that she had formerly only done in her cunt and ass, but now she let him pop her jaw loose and fuck his two feet of cock into her body all the way through her stomach. Meanwhile, the one humping away at her hiked-up anus was beating his sheath fully into her bowels so her buns were on his balls, and his two feet of cock was forcing her diaphragm up between her lungs. That was not yet a full four feet of horse cock, for her lips were still skinning back against her lover’s sheath, but it certainly was a delightful afternoon for a teenaged girl that could now wreak daily havoc on half a dozen of the biggest, horniest stallions on the planet. This was indeed quite an accomplishment for a girl that was a bit over five feet tall and weighed around a hundred pounds.
