You stand there feeling a strong attachment toward the big mare. The mare's actions seem to suggest feeling of hate or disgust, but you step close and stroke her smooth muscled flanks.
"She will learn to accept you as one of her protector's in time!" said the dark haired woman as she steps closer.
"She was a he, a man, a poor little hunched over man who wouldn't hurt a fly!" you exclaim.
"Quite right, he was a poor excuse for a man. Oh but with a little help in the right direction, see now his character. He has totally accepted being a mare! Watch as she does flex her hide at the touch of an insect. See the flicking of her tail as she uses it to calm her inner desires. Oh and watch those black lips of her vulva's sex as they wink in hope of some male's affection. Yes he has accepted and personally welcomes the life of a Percheron mare." says the woman with a kind smile.
"What of me?" you ask, wondering if you might soon be a mare of some stallion.
"Fear not! You are to be her protector I say. A stableboy to be sure, but also one who wishes to enjoy her sensual pangs. I see a youth of nineteen, six feet tall, broad shoulders, strong arms, legs, and well endowed. As if the bastard foal of a man with a mare you have black skin, a horse hairy body. Those ears are like the pony mare to which you were born from. A tail to show the beastial heritage! A sheath equal to a fine Dartmor stallion, testicles rich with equine seeds and last but niether least a penal shaft equal to the task. Now there you are a perfect stableboy. Perfect to his tasks and made to order for keeping his mares satisfied." the woman explains as your body responds to her every wish.
To a King's stable you go, a Percheron mare whinnies for her lover and you scratch at the crotch of those coarse pants.
