The girl continues to stroke your twitching member as you close your eyes to enjoy the sensation, your ears and feet feels strange to your senses but you are easily distracted by her wonderful massage, the girl whispers to you how aroused your cock is making her as your nose catch a sweet scent that cloud your thoughts, the itch in your tailbone stop as a luscious tail grow just above your bottom.
Lea smiles when she notices your brown equine ears and white tail flick as she massages your shaft, her smile transforms into a full smirk when you lose several inches of height and your penis continues to shrinks, remaining obvious to your changes.
The more the girl massages your member the more it shrinks and your form resemble an equine, your feet are now hard hooves and your new pelt is slowly creeping along your legs; the hands that fondled her breasts are now still along your sides as they pull into fists and the skin darkens.
His shaft finally disappears as a slit takes its place, blossoming like a flower in his (now her) nether region, the attendant examines the moist opening and then with a cruel smirk shoves two fingers in her new vagina, fondling the new girl with quick thrusts.
It was at this moment that the trance was broken, you gasp as the unfamiliar sensation register, you try to back away from her but Lea follow you without removing her fingers from your slit.
Your eyes widens as you see an opening where minutes before a proud cock stood erect and the other changes, you watch dazed as the skin around your vagina blacken until only a pair of puffy lips remains, the juices of your arousal slowly drip on the hay.
“W-What happened? What have you done?” A moan escapes your mouth as she flick the clit, smiling smugly as you gaze at her in horror.
“Don’t worry princess, in a few minutes you will only be a horny mare” You finally push her away, her fingers slip out of your opening, and you back away while her amused gaze follow your every move, a sudden cramp in your hands forces you to lift your hand to inspect the problem and your jaw drop as your hands transform into a pair of hooves.
“You can’t keep me here and change me! I have rights! I will ruin this place, just you wait”
“You’re free to go, nobody is holding you” She is openly laughing at you now, then turn to pick a bridle; realizing that this is your chance to escape, you try to bolt on your unsteady hooves, and you manage a groggy run until the stall door.
You can almost taste freedom, thoughts of forcing the zoo to reverse your changes and ruin this place with the press, when you notice the door is closed: a simple flush bolts lock the stall “Come on, open you stupid stall!” You fumble with the hooves but quickly realize that it’s impossible to open the doors without nimble fingers, you control left and right for a solution but the attendant is the only one in the stall able to open the lock.
Inspiration stuck you as you examines your strong haunches, you could try to kick down the door with your newfound horse strength, surely other horses didn’t manage to break stall doors before only because they were dumb beasts and didn’t understand the weak spots of a door.
To deliver a powerful kick you are forced to fall on all four, your hooves clop lightly as you position yourself before the door and rattle the stall with a powerful buck aimed at the joints of the door.
The stall is without a scratch and you try desperately to open a passage, while your transformation in a full mare is getting closer and closer, and after six other tries you realize with dread that there is no escape.
This plan failed but you still have time, you are not a full animal yet, you try to return to an erect position but after a few sways you fall again on all four with a loud whinny, your spine rearrange itself completely after the last fall to be completely equine. The attendant chose this moment to arrive.
“Are you done yet? Better studs than you have tried, none succeeded” She gestures to the bridle “Do you like it? I choose the more girly bridle I could find, bright pink with rose motifs, what do you think?”
“I think you should open the gate, you bitch! Let me go!”
“It’s useless now, it’s too late for you, in a bit you will only be a normal mare, owned by the zoo. Of course, if you are able to escape and hide for a week the spell will wear off and revert you to a man but if you have sex while a mare you will remain a horse for the rest of your life.”
You start to respond but only neighs and whinnies escapes your mouth, your face transform into a brown muzzle and your pelt finish to grow in all your body, making you a complete mare. The final changes enrage you and like a wild horse you buck without restraint, the attendant order you to stop and like magic you calm down and stood stock still. “The spell makes you mine princess, my words are law”
The girl before you secure the bridle around your muzzle as she lean against you and whisper in your ear that the fun part is yet to come.
