Monica shivered from millions of goose-pimples surrounded by billions of donkey fur folicles. She felt her body swell, as her shapely womanly form bloated out to make her barrel-gut. She watched with sullen feelings as her legs changed to hind equine donkey legs with hoofs. Monica weeped big tears as she witnessed her arms becoming her new fore-legs.
"Bray bray," cries Monica as her neck grew and her larynx conformed to being wholly equine.
The essence of her growing a tail was her realizing of how far her feminine self had degraded. She turned her changing head to gak a look back and down to see she had grown an udder with two teats. Her tail took to swinging due to her feeling nervous, as it brushed over her two most sensative areas, her puckered black anus and her weeping, winking black jennet vulva.
"You are almost ready to greet Damon, and I shall introduce the two of you to your new selves," Circe announced, as she smiled, seeing the head of Monica finish its conforming to a donkey skull, donkey teeth, and a broad tongue, as mouth and nose merged to form her whiskery muzzle.
"Come and follow me," Circe said, and Monica did as told.
Witch and victim walked along the marble halls, on slippery marble floors. Monica slipped twice and almost fell. Circe laughed at the difficulty that Monica had, but she turned a sour face when the jennet left something of a heap on the marble floor.
As they exited the rear of Circe's temple of doom, Damon stood calmly grazing, at peace with everything but his male erection.
"Please excuse the intrusion, but Monica has arrived and insisted she join you by her becoming a donkey jennet; the first jennet to your future herd!"
