David stood naked, he in a barn stall, a limply placed horse bridle set upon his still human head; as attached hung to reins, and they clipped into steel rings mounted to both side-posts to his stall.
"NO..., DAMN YOU CIRCE," David did yell as loud as he could!
Try as he did, but David could not get his hands to unclip the cross tie ropes, or defrock from off his head the black leather horse bridle.
"Don't be ah bothering to getting loose, Circe spell binds us, our minds and memories return to us when in our barn stalls. So yes, for the present you are human, a male, but soon to begin your changing; your genitals go first, then skin, and next comes body fur. Its later, during tonight when your bones readjust and change; and THAT, is painful !
Tomorrow, when the new you, you awake to being a colt Polo pony. Being first a colt, and allow then time to grow naturally, over many months to play, your bodily self strengthening, growing, maturing. When finally having grown to maturity, that is when Circe shall put you with four mares. You shall want by then of mating, having spent months masturbating. No matter what you think about Circe and her evil ways, you are powerless to deny or ignore her," so said a big Mule, he standing in a stall across from Dave.
"D.J. is me, her friendly and willing Polo pony!
You say sir that I shall learn to like what I will become, or in due time accept," so chuckled David, he wanting to scream from his terror.
"Karen, oh Karen, are you loose to come and favor our newest soon stallion with a freebee fuck session," so yelled the Mule?
"Coming dearie, coming for so cum getting," said a soft toned voice.
"Behold Karen, our half mule Centaur and barn manager, ain't she cute, she a Fjord breed; her vulva at just the perfect height for a human male to fuck!"
"Oh my, but he looks so cute, here boy, stick it into me and feel it grow..." Karen offering her body to David.
