[3 days later]
The attendant hadn’t been lying when she said that a filly’s heat was like torture.
Whilst the notion of having a horse’s vagina instead of your old human genitalia was distressing enough, the fact that it had become increasingly demanding was even more worrying. Whilst you were thankful that you couldn’t see it, you could still feel everything that was going on back there with revolting clarity. You knew the dreaded organ was wet and swollen with need. It created a painful throbbing deep inside you that was becoming more unbearable with every passing hour.
To your utter shame you had tried several techniques to relieve the intense discomfort coming from between your legs. The latest method involved rubbing your pussy against various parts of the stall. This process was far from ideal, but at least it acted as a temporary balm to soothe your aching body.
Humiliatingly you had been caught pleasuring yourself on several occasions by the passing stablehands. They would stop to mock you and joke about your misfortune before carrying on with their chores. Embarrassingly this did little to dissuade you. Instead you always resumed once the spectators had gone. The rush of orgasm that this technique eventually brought about served to temporarily dull the pain. Despite this though, the intense sensations never fully dissipated, leaving a nagging itch deep inside you which you would never be able to remove on your own. As disgusting as the thought was, you knew what your body wanted. The surge of warmth that arose in your loins whenever you looked at a stallion made you realise that the instinct to breed was getting stronger and stronger.
During the interludes in which you weren’t thinking about your sexual needs, your mind turned to more human concerns. You thought about your friends and family who would undoubtedly be worried after not hearing from you for a few days. Part of you wanted them to find you, but you knew that they would likely be cursed to share your fate if they did so. This inevitably reminded you of your girlfriend Jessica. The attendants had hinted that she was trapped in the Stables with you. Whether she was the white, blonde-maned female that you had been offered to ride when you first arrived was unclear. What was clear was that if she had been transformed as well it would only be a matter of days before you and her were stuck as animals forever.
It was whilst embarking on one of these depressing trains of thought that you were suddenly interrupted by Vicky, the attendant that had first welcomed you to the Stables. “Good morning Princess, how’s my gorgeous girl doing?” You snorted in annoyance. Having the name ‘Princess’ and being called ‘girl’ was humiliating, especially since she knew that you were really a man.
“Still a bit stroppy about your new name huh?” Vicky smiled as she slowly entered your stall and reached her hand up to play with your ears. You tried to scare her off by snorting and biting in her general direction, although this only made her chuckle. “Silly girl, need I remind you what will happen if you misbehave. Your darling girlfriend, or former girlfriend I should say, is still awaiting her first mate. It would be a shame for her to be broken in before she’s ready, and for you to see it too. How awful…”
You instinctively gave a whimpering whinny, not wanting Jessica to suffer further. You wanted nothing more than to trample the cruel bitch beside you to death, but you knew that doing so would have terrible repercussions for you and your girlfriend. As a result you bit your tongue and tried to quieten down, even though your whole body was seething with rage.
“That’s better Princess,” Vicky continued, “now then, I see that you’ve turned into quite a horny little minx, haven’t you?” You remained silent as she pointed out several areas where your vaginal juices had been smeared against the wall. “Do not be ashamed, it is good for a young filly to explore her body. I’ve seen you eyeing-up my stallions Princess, don’t think I don’t know exactly what you want.”
You neighed in humiliated defiance, knowing that Vicky’s words were undeniably true.
“Just imagine it,” Vicky continued, “a handsome stallion on your back, pounding that cute pussy of yours… filling you with his delicious cum. Doesn’t that all sound wonderful?”
You tried to confidently say ‘NO!’ Sadly all that came out was another shaky whinny as images of stallions started to cloud your mind.
You then began to tremble as Vicky ran her hand down your long muscular neck and back over your flank. She walked towards your rear where she rubbed and traced her hand over your large firm rump. The woman’s touch was oddly sensual, as if she knew exactly how to turn a horse on.
The woman continued until she was right behind you. She lifted your tail and paused for a moment as she stared intently at what lay between your legs. “I see this is the source of your discomfort” Vicky said with a chuckle. “What would you say if I offered to help with your predicament?”
You gave another shaky snort of defiance as you looked away, even though deep down you really wanted her help.
“Are you sure…” Vicky said teasingly as she reached forward. You whinnied out in surprise when you felt a finger gently running over your puffy vagina. You felt the digit slowly tracing around the teardrop-shaped organ before it started to slowly rub over the slit itself.
You did your best to keep your composure as you felt the familiar warmth returning to your loins. However, you couldn’t contain a shrill whinny when you were penetrated for the first time. It was only a gentle press forward, but the way the finger caressed and tickled your vagina’s sensitive inner walls sent jolts of pleasure running down your spine. You stepped forward, knowing this was wrong. But Vicky stepped with you, after which your stance relaxed and you let the woman have her way with you.
Vicky continued to tease you for a few more minutes. You couldn’t deny the pleasure you were feeling as her finger rubbed and massaged the pink flesh inside your passage. You could hear wet sounds as your arousal built, sending a few strands of fluid spilling out around the probing digit. You could also feel your vulva beginning to open and close rhythmically as your equine clitoris flashed itself to the world. The whole process was utterly disgusting, but in that moment the pleasure you were experiencing was far more important.
That was why you were so horrified when it suddenly stopped. You looked back in dismay to see that Vicky had taken a step back. You whinnied in frustration and need, begging her to continue. But Vicky just smiled at your apparent distress. She wiped the fluids off her finger using your tail before she returned to your front.
“As I suspected; definitely a filly in season.” You looked at Vicky sadly, desperately hoping that she would stop tormenting you. “Awww don’t look at me like that girl. As it happens I may be willing to help ease your suffering.”
Your ears perked up and your eyes widened hopefully. You would do almost anything to make the tortuous pain go away.
“Haha, glad you’re so eager Princess” Vicky continued. “Well as promised your training begins today. If you behave yourself, not only will your equine life be a happy one, but I will also help you out with that needy pussy of yours.” You shuddered at that thought as you felt your vagina continuing to wink open and closed behind you. “Disobey me however and you will likely end up as a broodmare, used simply to churn out foals and entertain the studs. Who knows, Jessica might even wind up joining you…”
You snorted and stomped your hooves angrily. Why couldn’t they just leave Jessica out of this!?
“Ah I take that to mean that you won’t cooperate,” Vicky said as she turned slowly, “oh well, I guess we’ll make good money from selling two fillies to the breeders. I suppose I’ll go and give them a quick call…”
You whinnied out pitifully, making Vicky turn to look back at you. “Awww have you learned to behave like a good horse Princess? Should I give you another chance?”
Vicky chuckled as you bowed your head and snorted sadly.
“Well in that case,” Vicky continued, “I think it’s time for your first lesson.” You looked up to see that the woman had produced a bridle and rope. “Now remember, your behaviour will determine your fate and Jessica’s. I’m sure you won’t let me down.
Your head swam with a mix of anger, fear and shame as you allowed Vicky to fit the bridle and begin leading you outside for your first lesson. You did you best to focus on the task at hand, although the nagging itch within your loins continued to demand attention.
Meanwhile you couldn’t help noticing that Vicky had a spring in her step. Clearly she was eager to get started with your first lesson...
