"Behold, you are for my summer months a my personal Familiar, servant, and passionate lover," The woman witch stated, as you with your usual dull wits asked of her, "This is now me, my legs, feet, I have hocks and cloven hoofs" as twisting the hips, "and a tail, what then as horns out my forehead, ears like a goat, and my, my, where is my penis?"
"Ha, your perfect for my purpose, and yes you still have a penis, check your furred navel, and trace down two inches, as wha-la, you have the sheath of a buck goat!"
"I, I am your satyr, for all the summer months, as being this earns me five granted wishes," you asked, as combing your fingers through fast thickening curls of goat fur growing to cover you from just above your navel, to groin, your butt, thighs and lower legs.
"My oops, your head, ears and a muzzle you still need as changed, I want a familiar with a long goat tongue for servicing me, to keep my vagina cleaned; you shall now begin to lick at me, delving inside my hot vaginal tunnel and lick, lick, as lick me clean!"
"What, do wha..., naa..., naa...," as the muzzle formed, your ability to form words ceased, and her powers enveloped your mind, forcing you to do as ordered.
The witchy woman raised her left leg to better allow your muzzle to slide flush to her crusty cunt, as your tongue reaches deep, and tasted foul as gross fluids; some hers and the rest was semen spewed by her last male companion.
"Naa...," you moaned, as the witch was beautiful her face and body, she had failed to bathe or wash her nether lips region. Licking began then some need to chew the thickly congealed vaginal slime your tongue found clinging to her inner walls. "Naa, naa," you bleated, as oddly thee rank flavor was arousing your cock from its furred sheath.
"What is this, no no my Imp goat familiar, you my clean but never as not ever shall we mate!
Know this, as remember me well, if I were to let you mate with me, when you retract your cock, then you shall be as all a buck goat, and permanently a goat until you grow old, very old, as after a hundred years of being, living, and knowing you were a horny buck goat. As maybe a gifted wish while living being a goat; you shall breed with thousands of doe goats and lie missionary style on top of dozens of equally horny women.
You shall never physically age, but remain virile, as your big balls become insatiable with goat semen.
You could never wish for better than of being cursed by me, lest you become a virile donkey who prefers women more than a equine vulva.
Ah.. that feels better, my vagina is now clean again.
Familiar, is your tongue sore, no you say, well go to my barn and lick clean the vulvas of my milk cow, my three mares, and then the vile vulvas of my doe goat herd, all two hundred and ninety one; and report back to me when finished!"
"Naa," you bleated to agree and begin what would take weeks to complete...
