Running Free

"Go on, off you go. I'll get you after my lunch."

Emma unclipped the reins from Lucky Lizzy's bridle, letting her well-exercised and already-fed mare go off on her own into the grazing field where most of the ranch's other ponygirls were already roaming about for grazing time. There was a different stable hand here to check in and watch the mares than yesterday, an African-American girl who Emma had called "Tristina," checking in the rest of the arriving mares and hanging up gear underneath the square pop-up tent and taking idle sips from a large steel water bottle. She would be responsible for keeping an eye on the ponies, but mostly just to ensure none fell into the adjacent stream to the grazing field, bolt, or cause harm to others. It was rare, but some ponies would get over-competitive and attempt to "sabotage" other mares. The stable hand, her cattle prod, and a wooden horse stand under the tent were there as a deterrent.

"Go on, have fun, stretch your legs and cool down. You did great running around the practice ring. And I'll keep Rhea away from you so you can actually rest, Liz. See you in a couple hours!"

Lizzy watched her trainer move off with a few other trainers, seemingly talking about the upcoming competition season. The first weekend of the "real" season was only four weeks away now and they were feeling the crunch. And poor Lizzy was only on her first day of real training. And she was exhausted. She was still getting used to the weight of her pony boots and her thighs were burning as a result. With her hands still bound to her pelvic bones by the saddle around her abdomen, all Lizzy could do was stiffly saunter off and try to find somewhere out of the sun. She was feeling a bit toasted by the heat after spending a couple hard hours of running and training under the whip, getting a brief shower, and having a quick lunch in the stable. So now she was keen to find somewhere to relax out of the sun and rest.

As she began to wander, she saw a few clusters of other ponies wandering about, even spotting some familiar colors and faces but Lizzy didn't make an attempt to catch up to Checkers and her un-bitted friends. Lizzy slowly walks off but doesn't bother to canter or anything. Even if she hadn't been so tired, it seemed that just walking "normally" was permitted among the ponygirls when at the grazing field. In fact, appeared to Lucky that in this penned-in field almost anything was allowed for the mares. A real chance for them to loosen up a bit and relax in between the hours of hard running and fitness training. And as Lizzy meandered further out into the pasture, it seemed that a couple of mares were indeed loosening up.

Lizzy found herself coming to a stunned stop as she caught sight of two ponygirls nestled in a cluster of trees. Not exactly hidden from view but rather with one of the girls, a black-haired girl in a silver arm-binder keeping her arms behind her back pressing her petite chest into a tree as a brown-haired girl was standing behind her, arms bound similarly to Lizzy, wet-humping the former pony and moaning through her bit-gag. Lizzy stood and stared as the two ponies humped and mewled, pony boots stamping in the grass and tails swishing this way and that as they were fighting for balance and position as they pleasured themselves hands-free, restrained in their pony gear and clearly aroused by one another as Lizzy could see a healthy amount of fluids dripping out of each pony as she got closer, too enamored by the situation to back off, too curious for her own good as the brown-haired pony moaned loudly through her bit, thighs shuddering and collapsing onto her black-haired partner's back, quivering as pussy juice sprayed out freely between her legs and soaked the ground between her brown knee-high pony boots.

Slowly, the brown-haired pony slid off her partner and collapsed into the shaded grass on her back, legs spread and revealing to the approaching blonde a puffy, glistening, squirt-soaked cunt. Akin to Lizzy, it was smoothly-shaven and since her hands were also strapped to a saddle out of reach for the girl. Lucky felt herself feeling sympathetic for the panting pony. Still, Lizzy found herself amazed the girls could orgasm like that, but she had to admit she was teetering on the edge of orgasm herself just from being trussed up out here, so really she shouldn't be so surprised.

Cautiously, the smaller "bottom" mare peeled herself off of the smooth-barked tree and turned around, pressing her back against it to catch her breath. This gave her a very sudden and clear look at Lizzy who, for lack of a better word, was gushing at the display. Lizzy herself was already imagining herself in this spectacle, the humiliating image of being humped to orgasm...

The black-haired girl blushed and looked away, heaving into her bit gag as her knees pressed together to hide her leaking arousal but the air around the trio was scented with musky arousal and there was really no hiding it. Lizzy found herself pacing closer, soft little grunts serving as a query to the other bitted ponies. She had no idea what she was doing, but as she got close, the slightly shorter black-haired pony was blushing and avoiding eye contact as Lizzy got close enough to touch her even with her bound hands. She was nervous, feeling like a kid at a high school dance asking their crush to the dance floor. Their proximity made Lizzy's heart pulse and her head spin, every sensation of her body enhanced. She could feel the biting of the saddle around her waist. Emma had snugged it a bit tighter after her shower and hadn't noticed. Lizzy hadn't been able to complain. Her hooves -her feet- were sore. They'd been trapped in these heavy ponyboots for almost a full 24 hours now. The bit in her mouth tasted far more rubbery than usual. And all the same, she couldn't pry herself away from the cute ponygirl. This felt illegal on the ranch, lusting after another pony. It probably was, especially for her. Emma sure wouldn't like it if she indulged in the lusts and pleasures that being a pony made Lizzy feel. But as the petite girl looked the taller blonde up and down, still panting, still desperate to cum just as hard as her brown-haired partner had, she slowly spread her legs to reveal a tiny set of labia and a river of juices running down her inner thighs, drooling an aroused slickness into the grass.

Lucky Lizzy through caution to the wind and pushed in. She lifted her right knee and pressed it to the smaller girl's petite slit, feeling it slickness and warmth on her bare and smooth skin. Lizzy's hands pressed flatly against the girl's ribs, given their slight height difference and her inability to reach elsewhere. The smaller girl's arms were still stuck in her silver leather armbinder and her shoulders wiggled and squirmed against the tree as Lizzy's weight pinned her to the sturdy tree. Lizzy was blushing like she had a fever as she ground her knee and thigh against the girl's cunt, the shorter girl panting and moaning softly into her bit as she rolled her head lazily from shoulder to shoulder, eyes shut, basking in the pleasure as the two ponygirls enjoyed one another's company out here in the grazing fields, open to view. Even amidst all the naughtiness of her action, the pleasure she was feeling from rubbing her bare leg against this girl's pussy, Lizzy still threw a couple glances over her shoulder to check for Emma or, much worse, Rhea. She could almost feel the strike of the crop against her pussy that her trainer employed to keep her focused. The poor blonde had been sweltering under her unexpected pleasures here and now was finally getting a chance to act upon them at her own pace.

Elizabeth was burning in shame, her cheeks flushed and her brow sweating as her body tingled from the insane taboo of her actions here. Out in a field, easily observed by others as more ponygirls milled about, as the brown-haired ponygirl was coming around from her after-orgasm daze. She'd been a sweet and sensible girl, even at college where things easily get off the rails. She'd denied dates and catcalls that her figure earned for her; even if she didn't want it to. And now here she was rubbing her leg across another girl's naked pussy, soaking her thigh in juices as she clenched on a plug-tail in her ass, panting into her rubber-coated bit and leaving horseshoe prints in the grass beneath them as the girl soaked her entire leg with a sudden, desperate, shaking orgasm. The black-haired pony's eyes shot open and screamed through her bit, baying like an animal as she squirted on and down Lizzy's leg, rocking forward and pressing her head into the larger girl's naked chest to try and balance into her, legs quivering and dropping out beneath her.

Lizzy panted quietly for a moment, head tilting back as she tried to grapple with her burning lust, her thighs twitching and pussy throbbing in need. She didn't even know why she had done that. Two days ago, she would have smacked anyone who suggested she would have masturbated a stranger in such a way. And here she was, doing just that.

"Yip!"

Lizzy jolted and looked down as she felt a tongue run across her labia. She saw a blushing, furtive face between her legs as the black-haired mare laid another slow, teasing lick across the new pony's pussy, making Lizzy quiver again as she leaned forward, pressing her forehead into the tree and panting, drooling onto the naked mare's back and tongue at the same time, from each of her lips. Lizzy huffed lewdly, mind going a bit blank as the black-haired ponygirl got her tongue deeper into Lizzy's pussy, seemingly giving a "thank you" for the orgasm. Lizzy huffed louder as she felt herself careening towards orgasm when she felt a brush of something soft between her soaked thighs and a kiss even lower than her labia, moaning as a second kiss hit her thigh, then just beside her plugged tailhole, on her ass cheek, and all the way up her back in frequent spots until she felt a warm breath beside her ear and a little nibble. She forced her eyes to open and saw the brown-haired mare pressing against her, hands touching where they could and batting her eyes at the blonde mare.

And Lizzy just could not hold back.

The ponygirl pushed her head back, feeling the second ponygirl's cheek against her own as she moaned into her bit, thighs clenching together around the black-haired mare's shoulders and her pussy soaked her face. Lizzy had found the other day, while getting tacked and fixed with her new tail, that she was indeed a squirter under the right circumstances and now this poor kneeling mare was getting a front row seat. Each shudder and clench of her body shot another burst of her fluids over the girl's face, making her mewl through her bit as the gag prevented her from fully closing her mouth and her committed position to nestle in between Lizzy's boots on her knees made it impossible to escape, even if Lizzy weren't clenching with her knees to keep upright.

Elizabeth's humiliating orgasm, being sandwiched in the most unexpected of ways, came to a quivering end as she leaned back forward, panting heavily as her chest rose and fell, eyes feathering shut as the two girls rested against her. It was perfect.

"You were supposed to be resting! I'm going to have to get you a chastity belt if you're going to be rutting around like that, Lizzy-busy. Though, on the other hand..."

Lizzy jolted again as she heard Emma's voice, shaking the brown-haired pony off her shoulder as she spun, completely caught as both of the other mares were still huddling around her, cuddling in that lurid post-orgasm glow.

Emma strode right up to her mare, a tiny smile on her face as she caught the bridle around Lizzy's head, pulling her head down slightly as Elizabeth's face burned red, ashamed she'd been caught like this by her cousin. She tried to step over and off the black-haired girl's face as Emma pulled her bridle a bit more, earning a little squeak of surprise and pain from the girl and a snicker from Emma at the clumsy movements of a post-orgasm mare.

"Maybe... instead of always punishing you and your... pony instincts... we should train them..."

As Emma clipped the reins back onto her bridle, Lizzy couldn't shake the feeling that she was in for a whole new level of humiliation...
