You stay stock still as you feel the stallion’s tongue moving and twisting in your vaginal canal!
You are a mare! Not a stallion as you thought! The stud continues to give you oral sex while your tail flick right and left nervously, and with growing horror feel as you are quickly becoming aroused by his ministration.
You started panting as the heat in your nether region becomes unbearable and you try weakly to distance yourself from the pleasure, but your lover once again twist his tongue in your wet folds and you surrender to the ministration, clopping a few steps behind to give him a better reach of your dripping vagina.
You turned your muzzle to look at him when Harry stopped licking you and withdrew his tongue, you almost wanted to order him to continue but you noticed the hungry and amused glint contained in his brown eyes, and with an epiphany you understood that the stallion behind you is likely a transformed human like you.
You whinny as a giant mass land on your back and the stallion is ready to take you, with your last shred of resistance you tried to dislodge him but Harry has you pinned! His cock start to poke you near your legs before he position his tool in the entrance of the wet canal, he rubs the head of his cock against your puffy lips to tease and humiliate you and then with deliberate slowness his shaft is inside you!
You shudder as the shaft slowly part your lips and enter your twitching folds, shame fills you when he makes you experience sex as a mare for the first time, the sensation of being filled an unexpected but pleasant experience, the cock buried in your vagina throbbed and the stud grunted when his balls slammed finally behind you, sheating his entire cock in your folds.
The stud then start the routine of mating, too lost in the throes of passion, and the sound of his lust spread in the clearing as he continues to spear the now horny mare with louds meaty slaps.
The stallion is clearly enjoying himself, Harry continues to hump you faster and faster, his tool now is sliding in and out without friction by the result of your arousal, in the middle of a thrust he bites your mane and with a pull brings you closer to him, in a moment of clarity you figure out that your life will be very different if you allow the stud to release his load inside you and by his grunting is not very far either.
This thoughts once again leave as you let out a powerful whinny when his powerful shaft throb inside your leathery folds and you feel your mounting orgasm coming, under normal circumstances you would be scared but your human mind is overshadowed by your new instincts that suppressed your horror of the situation and made you more aroused from the beginning of the mating.
Harry’s tool throb a final time and with dread you feel his load coat your inner walls white, mere moment later you came too as your vagina clamped down on his cock and you bask in the bliss of your orgasm, the previous dread forgotten, the stallion thrust his tool one last time in your vagina and emptied again inside of you.
With both your lust sated Harry dismount you and approach the attendant of the stables, only now you notice that she is near you with an halter and a dazzling smile.
You tried to distance yourself but the girl is faster and start to pet your neck with expert hands.
“ So how was Harry? I was not lying when I said that nobody ever complained, in fact everyone didn’t want to leave his tender care after a session of mating. Of course, the stables can house a select few horses so some are sold to farms and breeding centers, but the best animals remain with us” She secure the halter around your muzzle and start to play with your equine ears as you glare at her “Don’t look at me like that, you enjoyed it didn’t you? A shame that you choose Harry, if you took a mare then you would be the stud now… Oh well, there is always the next costumer, and a new broodmare always helps, I believe that your now former girlfriend will like the company” She start to hum a song as your reins lead you to your new home, the stables.
