Vicky left you and Lucy tied up in the arena as she went to fetch whatever she needed for the next part of her sick lesson. Your senses had gradually started to return as the pleasure of your recent foreplay frustratingly evaporated. You looked at the mare to see that she had the same amused, experienced look in her eyes which told you she had seen all of this before.
After a few minutes spent trying to come to terms with your perverse situation, Vicky finally returned. However you were surprised to find that she wasn’t alone. There was no mistaking who was following her: it was Harry!
You instantly backed away nervously as he locked eyes with you. The memories of your transformation came flooding back. Images of Harry thrusting into you and pumping you full of his sticky semen began running through your mind. You froze in horror as you felt the heat burning hotter in your loins, and the familiar sensation of your vagina beginning to open and close once again. You knew it was wrong to want Harry to fuck you again, but sadly your body was making it hard to resist him.
Vicky led Harry along until he was standing next to Lucy. All three of them then looked at you with cruel expressions of sick enjoyment etched on to their faces. Meanwhile you remained frozen in fear, desperately trying to hide your obvious signs of arousal that you had learnt about earlier in the lesson.
After a brief standoff, Vicky eventually broke the nervous silence. “Well Princess I’m happy to see that you are still fond of Harry here. I’m sure your body is aching to feel his heavenly cock, am I right?” You tried to give a defiant ‘no,’ but what came out was more of a desperate moan. “Well I’m sorry dear but you are still not fully trained. I can’t have you injuring our most prized stallion.”
Hearing this somewhat helped to snap you out of your lustful haze. He wasn’t going to screw you after all. You knew this was definitely a good thing, but your pussy still felt sore and in need of attention.
“Rather than you,” Vicky continued, “Harry is going to gift his precious seed to Lucy here. These two have already produced several adorable foals, and I hope that in a year’s time we will have another to add to the list.”
Harry and Lucy both snorted and grunted as they began to intimately nibble and stroke each other. As the couple circled each other you noted the mare’s vagina winking in anticipation. Seeing this gave you one emotion you hadn’t expected to feel: jealousy!
As you continued to stare longingly at the stallion and mare as they got frisky with each other, Vicky sauntered over to you. “Awww don’t envy her Princess, you will be bred by a big strong stallion when you are ready. For now though you will have to settle for this…”
With that Vicky produced a long rubbery object from behind her back. You soon realised it was a dildo, although this was different to any you had ever seen. It was black and rubbery and clearly made to resemble a stallion’s penis. The phallic object sported a bulbous tip, a long, thick shaft and a fake pair of hefty testicles at the base.
Seeing this strange sex toy made you feel slightly giddy inside. You knew where it would surely end up, and your body simply couldn’t wait. You neighed softly as you looked at Vicky pleadingly, begging her to fill your empty pussy.
“Ah, ah, ah,” Vicky said as she waved her finger, “you’ll have to earn your reward missy. Pretend that I’m a stallion and use the techniques Lucy showed you. Be quick about it or I may lose interest!”
You huffed in frustration as the sexual tension intensified. You wanted that cock so badly, even if it wasn’t a real one. All that mattered was feeling it stretch and fill you. You needed to cum so badly, which is why you decided to go along with Vicky’s perverse lesson.
The attendant chuckled as you turned away from her and started to shuffle into position. You looked up to see Lucy holding the posture you were aiming for as she looked back at Harry seductively. As for the stallion, his dick was now rock-hard and leaking pre-cum as he was seemingly mesmerised by the mare’s slick vagina as she flashed her clit to him.
Hoping to impress Vicky you gradually widened your posture and raised your tail, revealing your own winking vagina to her. “Impressive honey, but a mighty stallion like Harry would need more than that.”
You groaned again in annoyance as the need for release built up yet again. You thought back to the earlier part of the lesson as you tried to use your imagination for how you could seduce the pretend stallion. You remembered how Lucy had interacted with you, and so you decided to try and do the same.
Vicky said nothing as she let you follow your instincts. You turned to face the attendant before seductively walking towards her. You gave a suggestive neigh as you focussed on exaggerating the swaying of your ass behind you. As you approached, Vicky held out the dildo and looked at you encouragingly. With all hints of shame currently removed, you slowly leant your head forward and stuck your tongue out. You tasted the smooth rubber as you started to lick what would be the tip of the pretend stallion’s cock.
Vicky remained silent as you took more of the rubbery phallus into your mouth. You began to bob your head and swirl your tongue around the shaft as you started to lose yourself to the depraved act. At that moment you didn’t care how shamefully you were acting. In fact you simply shut your eyes and started to pretend that the dildo was a real stallion’s penis.
“That’s more like it! What a good girl!” You felt Vicky gently stroking and patting your neck with her free hand as she held the dildo up for you. She mumbled on a bit more about how you were ‘born to be a horse’ and ‘such an adorable filly,’ but these words largely fell on deaf ears. As you worked your way down to the dildo’s imitation testicles all you wanted was to feel the toy stuffed inside your needy cunt, nothing else mattered in that moment. Thankfully, Vicky was now ready to give you what you sought.
“Alright girl that’s enough. No stallion would be able to resist such an affectionate filly. You have earned your reward.” With that Vicky extracted the dildo from your mouth before she smeared a healthy dose of lubrication over its tip. In the meantime you returned to your previous stance. And there you stood with legs spread, tail raised and pussy winking, eagerly waiting for Vicky to satisfy your needs.
You didn’t have to wait long before you felt Vicky pressing the tip of the toy against your slick entrance. There was a brief pause, after which she increased the pressure and forced the dildo inside your eager passage. You let out a series of shrill whinnies as you felt the toy sinking into your depths. The way your sensitive folds wrapped around it sent pleasurable shockwaves reverberating through your body. You could feel your arousal reaching a fever pitch as a healthy stream of your juices was forced out between your parted pussy lips.
Things then got more intense when Vicky began thrusting. Your whole body shook and your vagina quivered as the rubber started to massage the sensitive pink flesh in the depths of your channel. Your pussy now winked furiously around the toy’s thick base as you continued to imagine that the wonderful penis belonged to a real stallion.
This train of thought caused you to look up at Harry and Lucy. By this stage they had moved past their cheeky foreplay to the point that they were now busy rutting passionately. From your side-on vantage point you were able to see the stallion stuffing his enormous penis into his mate’s vagina. Loud sloppy squelches would occasionally accompany Harry’s jabs as various sexual juices were compressed within the confines of Lucy’s passage.
In your lustful haze you found that you couldn’t take your eyes off the stallion’s organ as it remained firmly lodged inside Lucy’s pussy. Both horses were grunting passionately as they seemed to sense that they were nearing their climax. You knew you weren’t too far away either as Vicky increased her tempo, making the dildo hammer deep inside your stuffed vagina.
As it happened you and the others finished at about the same time. You heard Lucy whinny out in satisfaction as Harry shoved his dick deep into her folds. You could see the base of the organ shuddering in time with the twitching of his enormous testicles which undoubtedly meant that he was pumping his mate full of his rich semen. This was confirmed when Harry slid out of the mare, causing a stream of creamy white jizz to flow out in his wake.
Seeing the other two horses climax was enough to finally push you over the edge as well. Sensing that you were about to finish, Vicky pushed the dildo roughly forward, such that the rubbery balls pressed against your vagina’s stretched outer folds. You felt your inner walls grip the enormous toy as your pussy started to convulse in orgasm. You cried out as your body shook, after which you coated the dildo with a fresh spray of your pungent juices.
Your mind became warm and fuzzy as your body finally enjoyed the relief it had so desperately craved. You knew it was shameful that you had enjoyed such an act, but for the time being you couldn’t care less.
“There you are girl,” Vicky announced as she got up, leaving the dildo firmly wedged inside you. She walked over to your front where she started to stroke you possessively. “I think you are starting to realise how good your new body can make you feel. You saw how much Lucy enjoyed herself. One day you will be just like her, I know you will.”
You heard Vicky’s words but didn’t really react as you remained flushed from the intense orgasm.
Vicky moved to inspect Lucy’s cum-filled vagina, just to make sure that Harry had hit the mark. Seemingly satisfied, Vicky gestured for the two horses to look at you as she held up your tail. Both snorted in amusement as they saw your pussy still winking around the base of the toy that stretched you open.
“I think Princess is going to be a fine addition to the Stables, wouldn’t you two agree?” Harry and Lucy both whinied in unison as they agreed wholeheartedly. After that Vicky finally set about removing the giant dildo from your passage. It required a bit of twisting and pulling but it did eventually slip free, leaving you gaping open for a few seconds.
“Good girl Princess! Now I think you need to clean your new favourite toy!” With that Vicky brought the dildo round to your front. You obediently allowed her to insert the toy into your mouth, after which you began sucking and licking over the rubbery surface. Once again you didn’t mind how you tasted. You resolved that this small humiliation was well worth the pleasure that Vicky had granted you.
Once the toy was suitably clean Vicky finally called an end to the lesson and, after receiving a quick wash down from a stablehand, you were placed back in your stall amidst the other horses.
The rest of the afternoon was spent recovering from your taxing day and reflecting on your training so far. As the lust finally left your mind you began to realise just how far you had already fallen. Today you had once again acted like an animal in heat. You began to despair as you started to doubt whether there was any way out of this mess.
With little more to do than eat and wallow in self-pity, you decided that it would be wise to get a good night’s sleep. Regrettably your dreams were far from regular. Like the previous night they were filled with vivid scenes of horses mating, except this time you could feel your own pussy being filled, just like it had earlier in the day.
Unbeknown to you, you were having an intense wet dream as the heat in your pussy started to build up ready for tomorrow. But sadly there was nothing you could do to wake yourself from the prison of your own imagination.
All you could do was wait for dawn to break, and for your fifth lesson to begin…
