"Oh, fuck, yes! Yes! Fuck me harder!"
Dapple wakes to the sound of the mare in the next stall screaming in pleasure, accompanied by the grunts of a stallion and the hard rattling of the wooden wall that divides them. She flushes and sidles away from the wall, but she can't help listening in as her neighbor Stardance gets mounted.
"Yes! Yes! Finally! Oh, god, I'm coming! Yes!" Stardance howls, and then devolves into animal groaning as she climaxes. The stallion isn't done with her, though, and a few seconds later, she's crying again, "yes, yes, yes! Oh, fuck, please, keep going! I'm coming again! Fuck!"
Dapple flushes and stamps one of her hind hooves, then turns in an agitated circle, brushing a hand heatedly over the sensitive skin where her waist would be if she were a human. As a centaur, she's unable to reach her own sex to masturbate; for free centaurs, this isn't much of a concern--it's simple enough to find a willing partner, or to ask a friend for a hand--but Dapple is a pony centaur, kept in captivity her whole life, and she's never been selected for breeding.
Stardance, a racehorse centaur, is a valuable breeder, and it drives Dapple to distraction to hear the larger mare carry on during breeding season. She sidles back and forth in her stall, her pony cunt throbbing, and imagines how huge the centaur stallion must be who's giving Stardance a good, hard fuck.
"Oh, no, no, don't stop," Stardance wails as the stallion finally shouts his own climax. "No, I'm so close!"
"Yeah? Here you go, bitch," the stallion says, and there's the sound of a few loud, wet cracks--he's spanking her pussy, Dapple realizes, and her own clenches hard in sympathy, but Stardance apparently likes it because she screams in pleasure.
"Yes! Yes! Fuck! I'm coming!"
"Yeah you are," the stallion says, laughing. "God, I love how they keep you bitches so horny here. Ripe and ready for breeding. Want another one? Want me to rub your clit?"
"Yes! Oh, fuck, oh, fuck, thank you!"
Dapple shivers. Her own clit, hard and throbbing, twitches, and she can't hold back a quiet whinnying sound. The stallion apparently hears her and laughs.
"Who's that? Another bitch desperate to be fucked? I love this fucking stable. Maybe I'll take care of you next time, sweetheart."
Dapple flushes in mortification and covers her mouth, then closes her eyes as she feels a trickle of fluid escape from her fluttering sex and dribble down her haunch as her body responds to the idea of being mounted by a massive racehorse stallion. He would be too big, wouldn't he? Would it hurt?
Stardance squeals as she comes again.

Later that morning, the stablehand comes around and drops food into their troughs--apples, carrots, and so on. Dapple accepts her food and then, even though she knows better, her desperation drives her to say, "excuse me?"
The stablehand pauses and stares at her, frowning.
"Do you know...will I be bred this year?"
"Not my job to know that," he says shortly, irritably.
"Can you maybe--can you ask? Or can you ask if--if not--I hear there are, um, in some stables, they allow the mares to use t-toys--"
The stablehand scoffed. "We don't spend money on shit like that." As he walks away, he mutters, "fucking animals."
In the next stall, Stardance laughs meanly.

Exercise time was...difficult.
It was nice, of course, to get out of the stall, into the fresh air outside the stable. But--especially in breeding season--it was considered unsightly, with the centaurs being so similar to humans, to have their arousal on display. So they were fitted with the devices: oblong rubber shields that curved around their sex, covering their wet slit and their sensitive clits. The shields were held in place with a flared plug that sat just inside the cunt, not designed to pleasure, although inevitably the rub and press of it would leave many mares dripping. The fluid was caught inside the shield, hidden from the view of more delicate visitors who came to the ranch just to see the rare beasts.
The devices also served to prevent them from rubbing off against the fence or from pleasuring each other; any mare found to be helping another mare remove her device, or slipping her fingers up under it to provide pleasure, would be punished severely.
When Dapple is let out into the paddock, Stardance is already there, regaling her fellow racehorse mares with a lurid description of her stallion visitor. The tall mare whickers cruelly when she sees Dapple.
"Oh, there's the poor little pony. I heard you this morning, begging the stablehand to buy you a toy to fuck yourself on."
Dapple flushes as Stardance's friends all laugh. She stamps her foot.
"Yeah, well--well--I heard you moaning like a whore when that stallion spanked you!"
Several of the mares gasp, then laugh again. Stardance narrows her eyes, and Dapple immediately begins to back away, knowing that she's made a mistake.
"Grab her, girls," Stardance says. Dapple turns on her hooves and tries to leap away, but of course she's no match for the little herd of racehorses; they surround her, penning her in, laughing as she stamps and lunges at them in a panic.
Stardance comes up behind her and puts a hand on her flank, close to the rubber shield, and Dapple freezes, shivering. Stardance snickers.
"Poor, dowdy little Dapple. I suppose we should be more understanding, shouldn't we, girls? Your life must be so difficult. I don't think they're ever going to breed you." She pats Dapple's twitching hide. "Do you even know what it feels like to come?"
Dapple snorts in defiance, but the answer is written on her face. The other mares laugh again.
"Keep an eye out. Let's see if we can make little Dapple squeal," Stardance says, and then she slowly, carefully, nudges the hard rubber away from Dapple's skin, sliding her fingers up underneath.
